Referring to fig. 5, in some embodiments, the controller 11 is a device for controlling the operation of the driving member 13. In the present application, the operation of the control driving member 13 means: the controller 11 is capable of controlling the start and stop, rotational speed, torque, etc. of the driving member 13. The controller 11 may include an electric control housing 111 and an electric control component 113, where the electric control housing 111 is provided with a receiving cavity 1114. The electric control part 113 is arranged in the accommodating cavity 1114, the electric control part 113 is used for controlling the operation of the driving piece 13, and the cooling fluid is used for cooling the electric control part 113. In this embodiment, the electric control unit 113 includes a central control unit and a driving unit, where the central control unit is electrically connected to the driving unit to manage and control the driving unit to operate, and the driving unit is electrically connected to the driving member 13 to control the driving member 13 to operate. The central control unit is also used for being electrically connected with the remote communication end, the control end and the energy end so as to be responsible for managing and controlling the remote communication end, the control end and the energy end to operate, and interacting with the communication end, the control end and the energy end so as to realize multi-module cooperative operation. The remote communication terminal is a communication module for communicating with external terminal equipment, or a cloud server, or a network data terminal; the remote communication end can be arranged on the electric control part 113 or outside the electric control part 113 and is connected with the electric control part 113 through a cable; the control end is a control module for receiving a user control instruction and feeding back a control state to a user, the control end can be arranged on a control platform of the ship, and the control end can be a part of equipment or a combination of a plurality of equipment including a steering wheel, an electronic throttle lever, a touch control display screen and the like.

Specifically, in the case where the first heat dissipation assembly 23 drives the cooling fluid to flow between the heat exchanger 21 and the driving mechanism 10, the cooling fluid can flow through the electric control part 113 to achieve cooling and heat dissipation of the electric control part 113, whereby damage caused by overheating of the electric control part 113 can be prevented, thereby improving the stability of the operation of the driving mechanism 10. In addition, the arrangement of the electric control shell 111 can prevent the damage of the electric control part 113 caused by the direct contact of external impurities such as water or dust with the electric control part 113, thereby ensuring the normal operation of the electric control part 113 and prolonging the service life of the electric control part 113.

The driving member 13 is a device capable of converting electric energy into mechanical energy and outputting the mechanical energy to the outside. Referring to fig. 7, in the present application, the driving member 13 includes a driving body 131 and a driving housing 133. The driving body 131 is connected to a speed reducer 15, and the speed reducer 15 reduces the torque output from the driving body 131 and increases the torque. The driving housing 133 is sleeved on the driving body 131, and the cooling fluid passes through the driving housing 133 to cool the driving body 131.

Specifically, in the case where the first heat dissipation assembly 23 drives the cooling fluid to flow between the heat exchanger 21 and the driving mechanism 10, the cooling fluid can flow in the driving housing 133 to achieve cooling and heat dissipation to the driving body 131, whereby the driving member 13 can be prevented from being damaged due to overheating of the driving body 131 during operation, and the stability of the operation of the driving mechanism 10 can be improved. It should be noted that, in some embodiments, the driving member 13 may be a motor. The motor comprises, but is not limited to, a direct current servo motor, an alternating current servo motor, a stepping motor and the like.

In addition, in some embodiments, the electric control housing 111 may be connected to the driving housing 133, that is, the controller 11 may be designed integrally with the driving member 13, so that the overall size of the controller 11 and the driving member 13 is smaller than that of the electric control housing 111 and the driving housing 133, which can reduce the volume of the driving mechanism 10, thereby being beneficial to miniaturizing the power device 100; on the other hand, the distance between the controller 11 and the driver 13 can be reduced, thereby reducing the time required for the cooling fluid to flow between the controller 11 and the driver 13, and further improving the cooling efficiency of the cooling mechanism 20 to the driving mechanism 10. It should be noted that, in some embodiments, the electric control housing 111 and the driving housing 133 may be connected by one or more of bolting, fastening, bonding, welding, or the like.

The speed reducer 15 is a device for reducing the rotation speed of the driving member 13 and increasing the torque. Referring to fig. 10 and 11, in the present application, the speed reducer 15 includes a housing 151 and a speed reducer body 153. The housing 151 is provided with a receiving chamber 1513, and the speed reduction body 153 is disposed in the receiving chamber 1513. Wherein, the speed reduction body 153 is connected with the driving body 131, and the cooling fluid is also used for cooling the speed reduction body 153.

Specifically, in the case where the first heat dissipation assembly 23 drives the cooling fluid to flow between the heat exchanger 21 and the driving mechanism 10, the cooling fluid can flow in the housing 151 to achieve cooling and heat dissipation to the speed reduction body 153, whereby damage caused by overheating of the speed reduction body 153 during operation of the speed reducer 15 can be prevented, and the stability of the operation of the driving mechanism 10 can be improved.

In some embodiments, the reducer 15 and the driver 13 may be coaxially connected (i.e., the central axis of the output shaft of the driver 13 coincides with the central axis of the rotating shaft 1533 of the reducer 15), so that the coaxial accuracy of the connection between the driver 13 and the reducer 15 can be improved, and the working stability of the driving mechanism 10 can be improved. In addition, in some embodiments, the housing 151 is connected to the driving housing 133, that is, the speed reducer 15 can be integrally designed with the driving member 13, so that the overall size of the speed reducer 15 and the driving member 13 is smaller than that of the speed reducer 15 and the driving member 13, so that on one hand, the volume of the driving mechanism 10 can be reduced, which is beneficial to the miniaturization of the power device 100; on the other hand, the distance between the speed reducer 15 and the driving element 13 can be reduced, so that the time required for the cooling fluid to flow between the speed reducer 15 and the driving element 13 can be reduced, and the cooling efficiency of the cooling mechanism 20 on the driving mechanism 10 can be improved. It should be noted that, in some embodiments, the housing 151 and the driving housing 133 may be connected by one or more of bolting, snapping, bonding, welding, or the like.

In some embodiments, the heat exchanger 21 is a device capable of transferring a portion of the heat of a hot fluid to a cold fluid. The heat exchanger 21 is typically composed of a series of pipes, plates or other forms of heat transfer surfaces through which the heat of the hot fluid can be transferred to the cold fluid, thereby effecting heat transfer and balancing. In the present application, the heat exchanger 21 is capable of transferring heat in the cooling fluid to the external cooling fluid, thereby allowing the external cooling fluid to cool the cooling fluid. Specifically, after the cooling fluid cools the driving mechanism 10, the temperature of the cooling fluid rises, that is, the cooling fluid flowing into the heat exchanger 21 is a hot fluid, and the temperature of the external cooling fluid flowing into the heat exchanger 21 from the outside is lower than the cooling fluid, that is, the external cooling fluid flowing into the heat exchanger 21 from the outside is a cold fluid, and the external cooling fluid and the cooling fluid can perform non-contact heat exchange in the heat exchanger 21, whereby the external cooling fluid can cool down the cooling fluid, thereby making the cooling fluid flowing out of the heat exchanger 21 become cold fluid again, and further ensuring that the cooling fluid can cool the driving mechanism 10.

Wherein, the non-contact heat exchange can be: the external cooling liquid and the cooling fluid are not in contact with each other in the heat exchanger 21 and heat transfer can be achieved. For example, in the case of having a plurality of pipes in the heat exchanger 21, the external cooling liquid may be located inside the pipes and the cooling liquid outside the pipes, whereby the external cooling liquid and the cooling liquid can achieve heat transfer through the surfaces of the pipes.

The cooling fluid includes, but is not limited to, water, a coolant, or a cooling gas, etc. Wherein the coolant includes but is not limited to ethylene glycol or propylene glycol, etc.; the cooling gas includes, but is not limited to, ammonia or hydrogen, etc. In the present application, impurities are present in the cooling fluid little or no, whereby the cooling fluid does not affect the cooling effect of the cooling fluid on the driving mechanism 10 due to precipitation of impurities when the cooling fluid flows between the heat exchanger 21 and the driving mechanism 10, so that the heat radiation efficiency of the heat radiation mechanism 20 on the driving mechanism 10 can be ensured. For example, in the case where the cooling fluid is water, the water may be purified water.

The external cooling fluid includes, but is not limited to, water, coolant, cooling gas, or the like. Wherein the coolant includes but is not limited to ethylene glycol or propylene glycol, etc.; the cooling gas includes, but is not limited to, ammonia or hydrogen, etc. In the present application, the external cooling liquid may be external natural water, such as sea water or lake water, etc. Because the specific heat capacity of the external natural water is larger, that is, the temperature of the external natural water is not easily influenced by the outside to generate larger change, the external natural water can always maintain a lower temperature, so that the external cooling liquid is the external natural water, on one hand, when the external cooling liquid and the cooling fluid perform non-contact heat exchange in the heat exchanger 21, a larger temperature difference exists between the external cooling liquid and the cooling fluid, thereby improving the heat exchange effect and further improving the cooling effect of the cooling fluid on the driving mechanism 10; on the other hand, the outside natural water can be directly obtained from the outside, for example, when the water area movable apparatus 1000 moves on the sea surface, the outside natural water (sea water) can be directly obtained from the sea, so that the supply amount of the outside cooling liquid can be ensured, and the cooling liquid can be prevented from being effectively cooled due to insufficient outside cooling liquid.

It will be appreciated that in other embodiments, the power device 100 may further include a storage member (not shown) in which the external cooling fluid is stored, so that the second heat dissipation assembly 25 can drive the external cooling fluid in the storage member to flow to the heat exchanger 21, so as to supplement the external cooling fluid in the storage member when the second heat dissipation assembly 25 obtains the external cooling fluid from the external environment with insufficient hydraulic pressure. If the second heat dissipating component 25 cannot obtain the external cooling liquid from the outside for a long time, the open external circulation cooling may be switched to the closed external circulation cooling, that is, the heat exchange with the cooling liquid in the heat exchanger 21 is performed in a non-contact manner and then flows back to the storage part, and the external cooling liquid heat exchanger is disposed in the closed external circulation cooling path, so that the heat of the external cooling liquid in the closed external circulation is temporarily taken away by the external air through the external cooling liquid heat exchanger. The type of the external cooling liquid stored in the storage element is the same as that of the external cooling liquid in the above embodiment, and will not be described herein.

Referring to fig. 2 and 3, in some embodiments, the power device 100 may further include a housing 50, where the housing 50 covers the driving mechanism 10 and the heat dissipation mechanism 20, so that the housing 50 can provide a good protection effect for the driving mechanism 10 and the heat dissipation mechanism 20, and prevent the driving mechanism 10 and the heat dissipation mechanism 20 from being damaged due to collision with an external device, thereby ensuring normal operation of the power device 100.

Referring to fig. 1, in some embodiments, the power plant 100 may be applied to a propeller 300. The power device 100 may be connected to the propeller 310 of the propeller 300, and in the case where the driving mechanism 10 is operated, the driving mechanism 10 may drive the propeller 310 to rotate, so that the water movable apparatus 1000 may move on the water surface. Specifically, the speed reducer 15 in the driving mechanism 10 can be connected to the propeller 310, and in the case where the driving piece 13 is operated, the speed reducer 15 transmits the driving force generated by the driving piece 13 to the propeller 310 so that the propeller 310 can be rotated.

In some embodiments, the heat dissipation mechanism 20 may continuously operate to cool and dissipate heat of the driving mechanism 10 under the condition that the driving mechanism 10 is operating normally, so as to ensure the stability of the operation of the driving mechanism 10. In other embodiments, when the driving member 13 is operated, the heat dissipation mechanism 20 may be intermittently operated to cool and dissipate heat of the driving mechanism 10, that is, the heat dissipation mechanism 20 may be alternately operated and rest at preset time intervals, so that the intermittent operation of the heat dissipation mechanism 20 may not only ensure the heat dissipation effect of the heat dissipation mechanism 20 on the driving mechanism 10, improve the stability of the operation of the driving mechanism 10, but also reduce the power consumption required by the operation of the heat dissipation mechanism 20.

In the power device 100 of the present application, the heat dissipation mechanism 20 includes a heat exchanger 21, a first heat dissipation component 23 and a second heat dissipation component 25, the first heat dissipation component 23 is used for driving a cooling fluid to flow between the heat exchanger 21 and the driving mechanism 10 so as to cool the driving mechanism 10, and the second heat dissipation component 25 is used for driving an external cooling fluid to flow between the outside and the heat exchanger 21 and perform non-contact heat exchange with the cooling fluid in the heat exchanger 21 so as to cool the cooling fluid.

Power plant 100 is further explained below with reference to the drawings.

Referring to fig. 2 to 4, in some embodiments, the driving mechanism 10, the heat exchanger 21 and the first heat dissipation component 23 together form a first heat exchange circuit 30, and the cooling fluid flows in the first heat exchange circuit 30. The heat exchanger 21, the second heat sink assembly 25 and the cooling source of the external environment together form a second heat exchange circuit 40, the external cooling liquid flowing in the second heat exchange circuit 40, the first heat exchange circuit 30 and the second heat exchange circuit 40 being thermally coupled in the heat exchanger 21.

Specifically, in some embodiments, the driving mechanism 10, the heat exchanger 21 and the first heat dissipation component 23 are provided with passages for cooling fluid to flow, and the passages on the driving mechanism 10, the heat exchanger 21 and the first heat dissipation component 23 are communicated with each other to form a first heat exchange circuit 30, so that the cooling fluid can circulate in the first heat exchange circuit 30 to form a closed internal circulation cooling path; accordingly, passages for flowing the external cooling liquid are provided in the heat exchanger 21 and the second heat dissipation assembly 25, and the passages on the heat exchanger 21 and the second heat dissipation assembly 25 communicate with the cooling source of the external environment to form the second heat exchange circuit 40, so that the external cooling liquid can circulate in the second heat exchange circuit 40 to form an open external circulation cooling path.

In this case, since the cooling fluid is able to exchange heat with the controller 11, the driving element 13, and the speed reducer 15 when the cooling fluid flows through the driving mechanism 10, the temperature of the cooling fluid flowing out of the driving mechanism 10 increases, the warmed cooling fluid is able to continue to flow in the first heat exchange circuit 30 and enter the heat exchanger 21, while the temperature of the external cooling fluid is lower than that of the warmed cooling fluid, heat exchange is able to be performed between the cooling fluid in the first heat exchange circuit 30 and the external cooling fluid in the second heat exchange circuit 40 when the external cooling fluid is thermally coupled in the heat exchanger 21, and since the external cooling fluid and the warmed cooling fluid have a temperature difference, the external cooling fluid is able to cool down the cooling fluid, and the cooled cooling fluid is able to continue to flow in the first heat exchange circuit 30 to cool the driving mechanism 10.

In certain embodiments, the flow rate and flow rate of the cooling fluid in the first heat exchange circuit 30 is related to the output power of the drive mechanism 10. Specifically, when the output power of the driving mechanism 10 increases, that is, when the rotational speed of the propeller 310 (shown in fig. 1) increases, the amount of heat generated by the driving mechanism 10 increases, and in this case, if the flow rate and flow rate of the cooling fluid in the first heat exchange circuit 30 do not change accordingly, the cooling fluid cannot effectively dissipate heat from the driving mechanism 10, and the driving mechanism 10 is damaged. Therefore, when the output power of the driving mechanism 10 increases, the flow rate and the flow rate of the cooling fluid in the first heat exchange circuit 30 also increase, so that the heat radiation effect of the cooling fluid on the driving mechanism 10 can be ensured; accordingly, when the output power of the driving mechanism 10 is reduced, that is, when the rotational speed of the propeller 310 is reduced, the amount of heat generated by the driving mechanism 10 is reduced, and in this case, the flow rate and the flow rate of the cooling fluid in the first heat exchanging circuit 30 can be reduced, whereby the energy consumption of the power plant 100 can be reduced while ensuring the heat radiation effect of the cooling fluid on the driving mechanism 10. It will be appreciated that in the event of a change in the flow rate and flow rate of the cooling fluid in the first heat exchange circuit 30, the flow rate and flow rate of the ambient cooling fluid in the second heat exchange circuit 40 will vary. Specifically, when the flow rate and flow rate of the cooling fluid in the first heat exchange circuit 30 are increased, the flow rate and flow rate of the external cooling fluid in the second heat exchange circuit 40 are also increased; as the flow rate and flow rate of the cooling fluid in the first heat exchange circuit 30 decreases, the flow rate and flow rate of the external cooling fluid in the second heat exchange circuit 40 also decreases.

Referring to fig. 3 and 4, in some embodiments, the first heat dissipating component 23 includes a first conveying pipe 231 and a first suction piece 233. One end of the first transfer pipe 231 is connected to the heat exchanger 21, and the other end of the first transfer pipe 231 is connected to the controller 11. The first suction piece 233 is disposed on the first delivery pipe 231, the first suction piece 233 is for sucking the cooling fluid, and the first heat exchange circuit 30 includes an inner cavity of the first delivery pipe 231. It should be noted that, in some embodiments, the first suction piece 233 may be a pump or other device capable of performing suction.

Specifically, in some embodiments, in the case where the first suction piece 233 operates normally, the first suction piece 233 is capable of sucking the cooling fluid (the cooling fluid cooled down by the external cooling liquid) in the heat exchanger 21 into the inner cavity of the first delivery pipe 231 and pumping the cooling fluid in the inner cavity of the first delivery pipe 231 into the controller 11, thereby enabling the cooling fluid to cool down the controller 11.

Referring to fig. 5, in some embodiments, electronically controlled housing 111 includes a top cover 1115 and a base 1117, wherein top cover 1115 and base 1117 combine to form a housing 1114. Specifically, in some embodiments, the top cap 1115 and the base 1117 may be coupled using one or more of an adhesive, a weld, a threaded connection, or a snap-fit connection. The electric control component 113 is accommodated in the accommodating cavity 1114, and under the condition that the first suction piece 233 operates normally, the cooling fluid can flow into the accommodating cavity 1114 through the electric control shell 111 and perform non-contact heat exchange with the electric control component 113.

Further, referring to fig. 6, in some embodiments, the electronic control housing 111 is further provided with a first opening 1111 and a second opening 1113 spaced apart, and the other end of the first conveying pipe 231 is connected to the first opening 1111. The controller 11 further includes a loading member 115, the loading member 115 is provided with a flow channel 1151, one end of the flow channel 1151 is communicated with the first opening 1111, the other end is communicated with the second opening 1113, the electronic control unit 113 is mounted on the loading member 115, the first suction member 233 drives the cooling fluid to flow into the flow channel 1151 through the first opening 1111 and flow out of the second opening 1113, and the first heat exchange circuit 30 further includes the first opening 1111, the second opening 1113 and the flow channel 1151. It should be noted that, in some embodiments, the loading element 115 may be made of a material with good heat conductivity, such as copper, aluminum, or steel, so as to improve the heat exchange efficiency between the cooling fluid and the electric control component 113.

Specifically, in some embodiments, the loading member 115 may be a hollow structure, i.e., the interior of the loading member 115 is hollow, and the hollow is the flow channel 1151. Wherein, in the case of the normal operation of the first suction member 233, the cooling fluid in the first transfer duct 231 can enter the flow channel 1151 through the first opening 1111 and absorb heat generated from the electronic control part 113 mounted on the loading member 115, thereby achieving cooling of the electronic control part 113, and then the cooling fluid flows out of the electronic control housing 111 through the second opening 1113. It will be appreciated that in some embodiments, the cooling fluid can flow in a serpentine manner along the flow channel 1151 to cool the electronic control unit 113. As a possible implementation manner, since the driving unit of the electric control part 113 controls the driving member to operate, the heating value of the driving unit of the electric control part 113 is maximized, and the loading member 115 contacts with the driving unit of the electric control part 113, the temperature of the electric control part 113 can be effectively reduced. The electric control unit 113 comprises two sets of drive units, and the drive member 13 is provided with two sets of motor windings, namely two side-by-side stators and two side-by-side rotors, which are fixed on the same rotation shaft. The two sets of driving units are respectively and electrically connected with the two sets of motor windings to respectively drive the two sets of motor windings to operate, so that the operation power of the driving piece can be improved, and the manufacturing cost of the driving piece 13 can be simplified. The loading member 115 has opposite sides (a first side of the loading member 115 and a second side of the loading member 115), and two sets of driving units of the electric control unit 113 are respectively mounted on the opposite sides of the loading member 115, i.e., one of the sets of driving units is disposed at the first side of the loading member 115 and the other set of driving units is disposed at the second side of the loading member 115, so that the cooling fluid can cool down the two sets of driving units at the same time while the cooling fluid flows through the flow channel 1151, thereby improving cooling efficiency.

In some embodiments, the projection of the electrical control component 113 onto the carrier 115 at least partially coincides with the projection of the flow channel 1151 onto the carrier 115 in the direction of the electrical control component 113 onto the carrier 115, whereby the contact area of the cooling fluid with the electrical control component 113 is greater when flowing through the flow channel 1151 than when the projection of the electrical control component 113 onto the carrier 115 does not coincide with the projection of the flow channel 1151 onto the carrier 115, thereby enabling an increase in the cooling efficiency of the cooling fluid to the electrical control component 113.

Referring to fig. 3-6, in some embodiments, a first opening 1111 and a second opening 1113 are provided in the base 1117 and in communication with the flow channel 1151. Further, in some embodiments, the base 1117 is provided with a first connection channel 1118 and a second connection channel 1119, one end of the first connection channel 1118 is communicated with the first opening 1111, the other end is communicated with one end of the flow channel 1151, one end of the second connection channel 1119 is communicated with the second opening 1113, the other end is communicated with the other end of the flow channel 1151, and the first heat exchange circuit 30 further includes the first connection channel 1118 and the second connection channel 1119.

Specifically, in the case where the first suction piece 233 is normally operated, the cooling fluid in the first conveying pipe 231 can flow out of the electronic control housing 111 after passing through the first opening 1111, the first connection passage 1118, the flow passage 1151, the second connection passage 1119, and the second opening 1113 in this order, thereby achieving cooling and heat dissipation to the electronic control unit 113. The shape of the central axes of the first and second connection passages 1118 and 1119 may be linear or curved, etc., and is not limited herein.

Referring to fig. 3, 4 and 7, in some embodiments, the first heat dissipating assembly 23 further includes a second conveying pipe 235, one end of the second conveying pipe 235 is connected to the second opening 1113, the other end is connected to the driving housing 133, the second conveying pipe 235 is used for conveying the cooling fluid flowing out from the second opening 1113 into the driving housing 133, and the first heat exchanging circuit 30 further includes an inner cavity of the second conveying pipe 235.

Specifically, in the case where the first suction piece 233 is normally operated, the cooling fluid flowing out from the second opening 1113 can be pumped into the inner cavity of the second delivery pipe 235 and flow into the drive housing 133, whereby the cooling fluid can cool and dissipate heat of the drive body 131 in the drive housing 133. It will be appreciated from the foregoing that the drive housing 133 is coupled to the electrical control housing 111, and therefore the distance between the driver 13 and the controller 11 is smaller than if the drive housing 133 were not coupled to the electrical control housing 111, and therefore the length of the second delivery conduit 235 is shorter, thereby reducing the flow time of the cooling fluid in the second delivery conduit 235 and thus improving the cooling efficiency of the driving mechanism 10 by the cooling fluid.

Referring to fig. 8, in some embodiments, the driving housing 133 is provided with a cooling passage 1331, and a cooling fluid flows in the cooling passage 1331 to cool the driving body 131. Specifically, in some embodiments, the drive housing 133 may be a hollow structure, i.e., the interior of the drive housing 133 is hollow, and the hollow is the cooling passage 1331. Wherein, in case that the first suction piece 233 is normally operated, the cooling fluid in the second transfer duct 235 can enter the cooling passage 1331 and flow in the cooling passage 1331 to cool the driving body 131.

In some embodiments, the cooling channels 1331 have a cross-sectional area that is the same as the surface area of the outer peripheral wall of the drive housing 133, whereby the cooling fluid can cover the drive housing 133 in case the cooling fluid enters the drive housing 133, thereby enabling an omnidirectional cooling of the drive body 131.

In other embodiments, the cooling passages 1331 may extend in a serpentine manner along the circumference of the drive housing 133. For example, the cooling channel 1331 may be disposed on a circumference of the driving housing 133 in an "S" structure, so that when the cooling fluid enters the driving housing 133, the cooling channel 1331 bends and extends to increase the flowing time of the cooling fluid in the cooling channel 1331, so that the cooling fluid can exchange heat with the driving body 131 sufficiently, and further the cooling effect of the cooling fluid on the driving body 131 is improved.

Further, in some embodiments, the outer peripheral wall of the driving housing 133 is further provided with a first inlet 1332 and a first outlet 1333, the first inlet 1332 and the first outlet 1333 are both communicated with the cooling channel 1331, the first inlet 1332 is further communicated with the second conveying pipeline 235, the cooling fluid enters the cooling channel 1331 from the first inlet 1332 and flows out of the first outlet 1333, and the first heat exchange circuit 30 further comprises the first inlet 1332, the first outlet 1333 and the cooling channel 1331. It should be noted that, in some embodiments, the driving housing 133 may be made of a material with good heat conductivity, such as copper, aluminum, or steel, so as to improve the heat exchange efficiency between the cooling fluid and the driving body 131.

Referring to fig. 3, 4, 7 and 8, in some embodiments, the drive housing 133 includes opposite first and second ends 1334, 1335, the first end 1334 of the drive housing 133 facing the controller 11 and the second end 1335 of the drive housing 133 facing the decelerator 15. The drive housing 133 further includes a first stopper 1336, one end of the first stopper 1336 being connected to the first end 1334 of the drive housing 133 and the other end being connected to the second end 1335 of the drive housing 133, the first stopper 1336 being configured to partition the cooling channel 1331 to form a first sub-channel 13311 and a second sub-channel 13313 that are not in communication with each other, the first sub-channel 13311 being in communication with the first inlet 1332 and the second sub-channel 13313 being in communication with the first outlet 1333.

Further, in some embodiments, the second end 1335 of the drive housing 133 is provided with a second water outlet 1338 and a second water inlet 1339.

Specifically, in some embodiments, the second water outlet 1338 communicates with the first sub-channel 13311, the second water inlet 1339 communicates with the second sub-channel 13313, and thus, after the cooling fluid enters the first sub-channel 13311 through the first inlet 1332, the cooling fluid can dissipate heat from a portion of the driving body 131, and due to the arrangement of the first blocking member 1336, the cooling fluid cannot directly flow into the second sub-channel 13313, and thus, the cooling fluid can flow out to the outside through the second water outlet 1338 communicating with the second sub-channel 13313, and in addition, since the first end 1334 of the driving housing 133 can be connected with the electric control housing 111, the second end 1335 of the driving housing 133 can be connected with the housing 151, and thus, the cooling fluid can flow into the speed reducer 15 through the second water outlet 1338, and then flow out of the first water outlet 13313 through the second water inlet 1339, thereby enabling the cooling fluid to cool the driving member 13 and the speed reducer 15 at the same time, and improving the cooling efficiency of the cooling mechanism 20.

Still further, in some embodiments, the driving housing 133 further includes a plurality of second barriers 1337 spaced apart, and each of the plurality of second barriers 1337 is disposed in the second sub-channel 13313, and the second barriers 1337 are configured to limit the cooling fluid from flowing in the second sub-channel 13313, so that the cooling uniformity of the cooling fluid on the driving body 131 can be improved, and the cooling effect of the cooling fluid on the driving body 131 can be improved.

One end of the other of the adjacent two second stoppers 1337 is connected to the second end 1335 of the driving housing 133, and the other end is spaced from the first end 1334 of the driving housing 133.

Specifically, one of the adjacent two second stoppers 1337 extends from the first end 1334 of the drive housing 133 toward the second end 1335 of the drive housing 133 and is spaced from the second end 1335 of the drive housing 133, that is, a gap is provided between one of the adjacent two second stoppers 1337 and the second end 1335 of the drive housing 133; the other of the adjacent two second stoppers 1337 extends from the second end 1335 of the driving housing 133 toward the first end 1334 of the driving housing 133 and is spaced from the first end 1334 of the driving housing 133, that is, a gap is formed between the other of the adjacent two second stoppers 1337 and the first end 1334 of the driving housing 133, and under the condition that the first suction member 233 operates normally, the cooling fluid can flow in the second sub-channel 13313 in a bending manner, so that the flow time of the cooling fluid in the second sub-channel 13313 can be increased, thereby enabling the cooling fluid to perform sufficient heat exchange with the driving body 131, and further improving the cooling effect of the cooling fluid on the driving body 131.

In other embodiments, the second blocking member 1337 includes a first end and a second end opposite to each other, the first end of the second blocking member 1337 is connected to the first end 1334 of the driving housing 133, the second end of the second blocking member 1337 is connected to the second end 1335 of the driving housing 133, the second blocking member 1337 is provided with a through hole (not shown), the through hole is disposed at the first end of the second blocking member 1337, or between the second end of the second blocking member 1337, or between the first end of the second blocking member 1337 and the second end of the second blocking member 1337, and the through holes on two adjacent second blocking members 1337 are disposed in a staggered manner, so that the cooling fluid can also flow in the second sub-channel 13313, thereby increasing the flow time of the cooling fluid in the second sub-channel 13313, and further enabling the cooling fluid to exchange heat with the driving body 131 sufficiently, and improving the cooling effect of the cooling fluid on the driving body 131.

Referring to fig. 3, 7, 10 and 11, in some embodiments, the housing 151 is provided with a circulation channel 1511, and a first opening and a second opening in communication with the circulation channel 1511, the first opening being for cooling fluid to flow into the circulation channel 1511, and the second opening being for cooling fluid to flow out of the circulation channel 1511.

Specifically, in some embodiments, the first opening of the circulation channel 1511 is in communication with the second water outlet 1338, the second opening of the circulation channel 1511 is in communication with the second water inlet 1339, the first suction piece 233 drives the cooling fluid to enter the circulation channel 1511 through the second water outlet 1338 and the first opening and flow into the second sub-channel 13313 from the second opening and the second water inlet 1339, and the first heat exchange circuit 30 further includes the second water outlet 1338, the second water inlet 1339, the first opening, the second opening, and the circulation channel 1511. It should be noted that, in some embodiments, the housing 151 may be made of a material with good heat conductivity, such as copper, aluminum, or steel, so as to improve the heat exchange efficiency between the cooling fluid and the electric control component 113.

Specifically, in the case where the first suction member 233 is normally operated, the cooling fluid flowing out of the second water outlet 1338 can enter the circulation passage 1511 through the first opening and absorb the heat generated by the speed reduction body 153, thereby achieving cooling and heat dissipation of the speed reduction body 153, and the cooling fluid flowing out of the circulation passage 1511 can also enter the second sub-passage 13313 through the second opening and the second water inlet 1339 to perform cooling treatment on the driving body 131.

Further, referring to fig. 12, in some embodiments, the speed reducer 15 further includes a cooling oil contained in the containing chamber 1513, the cooling oil is used to cool and lubricate the speed reducer body 153, and the cooling fluid is also used to cool the cooling oil in a case where the cooling fluid flows through the circulation passage 1511. In some embodiments, the cooling oil may be a lubricating oil.

Specifically, in the case that the speed reduction body 153 moves, the cooling oil can directly contact with the speed reduction body 153, so that on one hand, the speed reduction body 153 can be lubricated, and the stability of the operation of the speed reduction body 153 is ensured; on the other hand, the heat generated by the speed reduction body 153 can be absorbed, and the speed reduction body 153 is prevented from being damaged due to overheating. In addition, the cooling fluid flowing through the circulation passage 1511 can cool the speed reduction body 153 while the cooling oil cools the speed reduction body 153, and in addition, the cooling fluid can also water-cool the cooling oil, so that the cooling effect of the heat dissipation mechanism 20 on the speed reducer 15 can be improved, and the utilization rate of the cooling fluid can be improved.

More specifically, in certain embodiments, the reduction body 153 includes a bearing 1531, a rotational shaft 1533, and a gear set 1535. The rotation shaft 1533 passes through the bearing 1531 and is connected to the driving body 131. The gear set 1535 is connected to the rotation shaft 1533, and when the driving body 131 works, the rotation shaft 1533 rotates to drive the gear set 1535 and the bearing 1531 to rotate.

In some embodiments, the bearings 1531 may be disposed on the housing 151, and the bearings 1531 include two bearings 1531, the rotation shaft 1533 rotatably penetrates through the two bearings 1531 and is connected with the propeller 310 of the propeller 300, the gear set 1535 is disposed between the two bearings 1531 and is connected with the output shaft of the driving body 131, and in the case that the output shaft of the driving body 131 rotates, the gear set 1535 can drive the rotation shaft 1533 to rotate so that the propeller 310 rotates together with the rotation shaft 1533, thereby realizing the movement of the water area movable apparatus 1000. The cooling oil can lubricate the gear set 1535 and the bearing 1531, so as to prevent the gear set 1535 and the bearing 1531 from being blocked, and further ensure the normal operation of the speed reducer 15.

Since friction and mechanical movement exist between the parts (including the bearing 1531, the rotating shaft 1533, the gear set 1535, and the like) of the speed reducer body 153 during the normal operation of the speed reducer 15, the speed reducer body 153 generates heat, which causes the air pressure in the accommodating chamber 1513 to rise, thereby increasing the friction resistance between the parts, and further causing the power output of the speed reducer 15 to be limited, and the expected rotation speed or torque output cannot be achieved. Therefore, in the present application, the speed reducer 15 further includes a pressure adjusting member 155, the pressure adjusting member 155 is disposed on the housing 151, and the pressure adjusting member 155 is used for adjusting the air pressure in the accommodating chamber 1513, thereby, on the one hand, the arrangement of the pressure adjusting member 155 can prevent the increase of the air pressure from causing the increase of the friction resistance between the parts, thereby preventing the limitation of the power output of the speed reducer 15 and ensuring that the speed reducer 15 can achieve the expected rotation speed or torque output; on the other hand, the damage to the structure of the speed reducer 15 caused by the excessive air pressure can be prevented, so that the service life of the speed reducer 15 is prolonged.

Referring to fig. 3, 12 and 13, in some embodiments, the housing 151 further includes a pressure release channel 1515, the pressure release channel 1515 is used for communicating the accommodating cavity 1513 with the outside, and the pressure regulator 155 is at least partially disposed in the pressure release channel 1515 to selectively open or close the pressure release channel 1515. Specifically, in some embodiments, in the event that the air pressure in holding chamber 1513 is too high, pressure regulator 155 can vent pressure relief passage 1515 to allow holding chamber 1513 to communicate with the outside world, thereby allowing the air pressure in holding chamber 1513 to be released; with the air pressure in the accommodating chamber 1513 in a normal state, the pressure regulator 155 closes the pressure relief passage 1515 to prevent leakage of the cooling oil in the accommodating chamber 1513.

In some embodiments, pressure relief channel 1515 is located on a side of bearing 1531 facing away from gear set 1535, one end of pressure relief channel 1515 is in communication with receiving chamber 1513, the other end of pressure relief channel 1515 is in communication with the outside, and pressure regulator 155 blocks the other end of pressure relief channel 1515.

Specifically, since the rotation shaft 1533 can rotate along with the output shaft of the driving member 13 when the output shaft of the driving member 13 rotates, and in this case, the gear set 1535 can also rotate and stir the cooling oil, the cooling oil may be sputtered under the stirring action of the gear set 1535, and if the pressure release channel 1515 is located between the two bearings 1531, the cooling oil may leak to the outside of the reducer 15 through the pressure release channel 1515, so that on one hand, loss of the cooling oil will be caused; on the other hand, the cooling oil will pollute the device such as the speed reducer 15. Therefore, in the present application, the pressure release channel 1515 is located on the side of the bearing 1531 away from the gear set 1535, and the pressure regulator 155 seals the pressure release channel 1515, so that on one hand, the normal implementation of the pressure regulator 155 on the air pressure regulating function in the accommodating chamber 1513 can be ensured; on the other hand, leakage of cooling oil to the outside of the speed reducer 15 through the pressure relief channel 1515 can be reduced or even avoided, so that loss of the cooling oil is reduced, and pollution of the cooling oil to the speed reducer 15 and other devices is prevented.

It should be appreciated that in other embodiments, the first suction piece 233 may further include a plurality of first suction pieces 233 disposed on the first conveying pipe 231, the second conveying pipe 235 and the third conveying pipe 237, respectively, so that the arrangement of the plurality of first suction pieces 233 can improve the stability of the operation of the first suction pieces 233, and prevent the cooling fluid from being unable to flow in the first heat exchange circuit 30 due to damage of a certain first suction piece 233, compared to the arrangement of the first suction piece 233 including only one.

It is understood that the walls of the heat exchange tube 213 are heat transfer surfaces for the cooling fluid and the external cooling fluid.

In other embodiments, the housing body 2117 and the two covers 2118 may be connected by a removable connection, such as a threaded connection or a snap-fit connection, so that the components in the heat exchange chamber 2111 may be easily removed for replacement if they are damaged (e.g., the heat exchange tube 213 is corroded, etc.).

Further, referring to fig. 16, in some embodiments, housing body 2117 includes opposite first and second sides 21171, 21173, a first perforation 2112 is provided through first side 21171 of housing body 2117, and a second perforation 2113 is provided through second side 21173 of housing body 2117. Where the water area movable apparatus 1000 is carried on the water surface, the first side 21171 of the case body 2117 is the bottom of the case body 2117 (the lowermost side of the case body 2117 in the heat exchanger 21 shown in fig. 3), and the second side 21173 of the case body 2117 is the top of the case body 2117 (the uppermost side of the case body 2117 in the heat exchanger 21 shown in fig. 3), whereby, in the case where the cooling fluid enters the heat exchanging cavity 2111 through the second perforation 2113, the cooling fluid can flow to the first perforation 2112 by the suction force of the first suction member 233 and the gravity of the cooling fluid itself, the power consumption of the first suction member 233 is smaller than that of the cooling fluid flowing to the first perforation 2112 by the suction force of the first suction member 233 alone, and thus the power consumption of the power apparatus 100 can be reduced.

In some embodiments, the heat exchanger 21 further includes a plurality of spaced barriers 219, where the plurality of barriers 219 are disposed in the heat exchange cavity 2111, and the barriers 219 are configured to limit the bending flow of the cooling fluid in the heat exchange cavity 2111, so as to increase the flow time of the cooling fluid in the heat exchange cavity 2111, and improve the uniformity of contact between the cooling fluid and the heat exchange tube 213, thereby improving the cooling effect of the external cooling fluid on the cooling fluid.

In some embodiments, one end of one of the two adjacent baffles 219 is connected to the first side 21171 of the housing body 2117 and the other end is spaced from the second side 21173 of the housing body 2117. One end of the other of the two adjacent barrier 219 is connected to the second side 21173 of the housing body 2117 and the other end is spaced from the first side 21171 of the housing body 2117.

Specifically, one of the two adjacent baffles 219 extends from the first side 21171 of the housing body 2117 toward the second side 21173 of the housing body 2117 and is spaced from the second side 21173 of the housing body 2117, that is, there is a gap between one of the two adjacent baffles 219 and the second side 21173 of the housing body 2117; the other of the adjacent two barrier members 219 extends from the second side 21173 of the housing body 2117 toward the first side 21171 of the housing body 2117 and is spaced from the first side 21171 of the housing body 2117, that is, a gap is provided between the other of the adjacent two barrier members 219 and the first side 21171 of the housing body 2117, and in the case of normal operation of the first suction member 233, the cooling fluid can flow in a bent manner in the heat exchange chamber 2111, thereby increasing the flow time of the cooling fluid in the heat exchange chamber 2111, enabling the cooling fluid to exchange heat sufficiently with the external cooling fluid, and further improving the cooling effect of the external cooling fluid on the cooling fluid.

Referring to fig. 17, in other embodiments, the barrier 219 includes a first end 2191 and a second end 2193 opposite to each other, the first end 2191 of the barrier 219 is connected to the first side 21171 of the housing body 2117, the second end 2193 of the barrier 219 is connected to the second side 21173 of the housing body 2117, a through hole (not shown) is formed in the barrier 219, and the through hole is located between the first end 2191 of the barrier 219 or the second end 2193 of the barrier 219 or between the first end 2191 of the barrier 219 and the second end 2193 of the barrier 219, and the through holes on two adjacent barriers 219 are offset, so that the cooling fluid can also bend in the heat exchange cavity 2111, thereby increasing the flowing time of the cooling fluid in the heat exchange cavity 2111, so that the cooling fluid can exchange heat with the external cooling fluid sufficiently, and further improving the cooling effect of the external cooling fluid on the cooling fluid.

Referring to fig. 3, 15 and 16, in some embodiments, the heat exchange housing 211 is further provided with a third perforation 2114 and a fourth perforation 2115, the third perforation 2114 of the heat exchange housing 211 penetrates one of the two covers 2118, and the fourth perforation 2115 of the heat exchange housing 211 penetrates the other one of the two covers 2118. The heat exchanger 21 further comprises two spaced mounting plates 215, the mounting plates 215 are abutted to the inner peripheral wall of the heat exchange housing 211 and form a heat exchange cavity 2111 together with the heat exchange housing 211, two mounting plates 215 are respectively arranged at two ends of the heat exchange pipeline 213 in a penetrating mode, a first circulation pipeline 251 of the second heat dissipation assembly 25 is communicated with one end of the heat exchange pipeline 213 through a third perforation 2114, and a second circulation pipeline 255 of the second heat dissipation assembly 25 is communicated with the other end of the heat exchange pipeline 213 through a fourth perforation 2115.

Specifically, the mounting plate 215 abuts against the inner peripheral wall of the case body 2117, and the two mounting plates 215 are respectively pierced at both ends of the heat exchanging pipe 213, whereby both ends of the heat exchanging pipe 213 can communicate with the third perforation 2114 and the fourth perforation 2115 on the two covers 2118, respectively, that is, one end of the heat exchanging pipe 213 can communicate with the first circulation pipe 251 connected to the third perforation 2114, and the other end of the heat exchanging pipe 213 can communicate with the second circulation pipe 255 connected to the fourth perforation 2115. Under the condition that the second suction piece 253 operates normally, the external cooling liquid can flow through the inner cavity 2511 of the first circulation pipe 251, the third perforation 2114, the inner cavity of the heat exchange pipe 213, the fourth perforation 2115 and the inner cavity of the second circulation pipe 255 in sequence and then flow out of the electric control housing 111, so that the external cooling liquid can cool and dissipate heat of the cooling fluid.

Referring to fig. 14-16, in some embodiments, the heat exchanger 21 further includes a seal 217, the seal 217 being disposed between the mounting plate 215 and the inner peripheral wall of the heat exchange housing 211, the seal 217 being configured to seal a gap between the mounting plate 215 and the inner peripheral wall of the heat exchange housing 211.

Specifically, in certain embodiments, the seal 217 may be disposed between the mounting plate 215 and the inner peripheral wall of the housing body 2117, whereby the seal 217 is able to seal the gap between the mounting plate 215 and the inner peripheral wall of the housing body 2117, preventing the cooling fluid in the heat exchange chamber 2111 from flowing out of the heat exchanger 21 through the gap, reducing or even avoiding loss of the cooling fluid. Wherein the material of the seal 217 includes, but is not limited to, rubber, plastic, or silicone, etc. Or the seal 217 may also be a sealing grease.

In certain embodiments, the outer peripheral wall of the heat exchange tube 213 is provided with a plurality of spaced apart protrusions 2131, the protrusions 2131 extending from the outer peripheral wall of the heat exchange tube 213 towards the inner peripheral wall of the heat exchange housing 211. Specifically, the contact area between the heat exchange pipe 213 and the cooling fluid can be increased by the protrusion 2131, that is, the heat exchange area between the external cooling fluid and the cooling fluid is increased, so that the heat exchange efficiency of the external cooling fluid to the cooling fluid can be improved, and the heat exchange effect of the external cooling fluid to the cooling fluid is ensured.

Because the temperature of the cooling fluid flowing from the first perforations 2112 into the heat exchange chamber 2111 is higher, the temperature of the cooling fluid may cause the air pressure in the heat exchange chamber 2111 to increase, resulting in an increase in the flow rate of the cooling fluid in the heat exchange chamber 2111, which in turn causes a decrease in the heat transfer efficiency; also, the increase in air pressure in the heat exchange chamber 2111 may also cause breakage of the structure of the heat exchanger 21 (e.g., the heat exchange housing 211 or the heat exchange tube 213, etc.), resulting in a shortened service life of the heat exchanger 21. Accordingly, referring again to fig. 14 to 16, in the present application, the heat exchanger 21 further includes an adjusting member 218, the adjusting member 218 is mounted on the heat exchange housing 211, and the adjusting member 218 is used for adjusting the air pressure in the heat exchange cavity 2111, thereby, the arrangement of the adjusting member 218 can prevent the air pressure in the heat exchange cavity 2111 from increasing to increase the flow speed of the cooling fluid in the heat exchange cavity 2111, that is, prolong the residence time of the cooling fluid in the heat exchange cavity 2111, so as to improve the heat transfer efficiency; on the other hand, the structural damage of the heat exchanger 21 can be prevented, thereby prolonging the service life of the heat exchanger 21. It should be noted that in some embodiments, the regulator 218 may be a gas permeable cap or regulator 155, or the like.

In some embodiments, heat exchange housing 211 includes expansion space 2116, expansion space 2116 extending from the inner peripheral wall of heat exchange housing 211 in a direction away from the center of heat exchange chamber 2111, expansion space 2116 communicating with heat exchange chamber 2111, cooling fluid entering expansion space 2116 in the event that the temperature of the cooling fluid in heat exchange chamber 2111 is greater than a preset temperature.

Specifically, since the air pressure in the heat exchange chamber 2111 increases in the case where the cooling fluid flows into the heat exchange chamber 2111 through the first perforation 2112, resulting in an increase in the volume of the cooling fluid, the cooling fluid is liable to leak directly from the regulator 218 to the outside of the heat exchanger 21, resulting in a loss of the cooling fluid, thereby affecting the cooling effect of the cooling fluid on the drive mechanism 10. Moreover, leakage of cooling fluid directly through the adjustment member 218 may also cause damage to the adjustment member 218, affecting the useful life of the adjustment member 218. Therefore, in the present application, when the temperature of the cooling fluid is higher than the preset temperature, the cooling fluid can enter the expansion space 2116, and at this time, the air pressure in the heat exchange chamber 2111 can be released to a certain extent, that is, the adjusting member 218 does not need to release the air pressure in the heat exchange chamber 2111, so that the arrangement of the expansion space 2116 can prevent the cooling fluid from directly leaking from the adjusting member 218 to the outside of the heat exchanger 21, thereby on one hand, reducing or even avoiding the loss of the cooling fluid, and ensuring the cooling effect of the cooling fluid on the driving mechanism 10; on the other hand, damage to the adjusting member 218 caused by leaked cooling fluid can be avoided, and the service life of the adjusting member 218 is prolonged.

It will be appreciated that in one embodiment, the regulator 218 is mounted to the heat exchange housing 211 and communicates directly with the heat exchange chamber 2111, whereby the regulator 218 is able to directly release the air pressure in the heat exchange chamber 2111 when the air pressure in the heat exchange chamber 2111 increases to the desired level. In another embodiment, the regulator 218 is mounted to the heat exchange housing 211 and communicates directly with the expansion space 2116, whereby the regulator 218 is able to release the air pressure in the expansion space 2116 when the air pressure in the heat exchange chamber 2111 increases to increase the air pressure in the expansion space 2116 and the air pressure in the expansion space 2116 increases to the point where release is desired.

Referring again to fig. 14-16, in some embodiments, the heat exchange housing 211 is further provided with a fifth perforation 2119, the fifth perforation 2119 is in communication with the heat exchange cavity 2111 and the outside, and the fifth perforation 2119 is used for the cooling fluid in the heat exchange cavity 2111 to flow out to the outside.

Specifically, in some embodiments, the heat exchanger 21 may further include a blocking member 216, where the blocking member 216 is capable of blocking the fifth perforation 2119 in the case where the heat exchanger 21 is operating normally, so that leakage of the cooling fluid in the heat exchange chamber 2111 can be prevented; in the event of excessive cooling fluid or maintenance, the user can open the closure 216 to allow the heat exchange chamber 2111 to be connected to the outside through the fifth perforation 2119, in which case at least part of the cooling fluid in the heat exchange chamber 2111 can flow out to the outside through the fifth perforation 2119.

A regulator 155 is provided to the housing 151, the regulator 155 being for regulating the air pressure in the accommodating chamber 1513. It is to be understood that the configuration of the decelerator 15 in the present embodiment is identical to that of the decelerator in the above embodiment, and the explanation thereof will not be repeated here.

In the speed reducer, the speed reducer 15 comprises the pressure regulating piece 155 arranged on the shell 151, and the pressure regulating piece 155 can regulate the air pressure in the accommodating cavity 1513, so that the arrangement of the pressure regulating piece 155 can prevent the air pressure in the accommodating cavity 1513 from being too high, the damage of the speed reducer 15 can be avoided, the service life of the speed reducer 15 is prolonged, and the normal operation of the speed reducer 15 is ensured.
