Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The cover plate assembly 100 of the present invention is described below in conjunction with fig. 1-7. It should be noted that the wind turbine may be a device for generating wind power, which may include a wind turbine tower and blades. The wind turbine tower barrel can be used for supporting blades, meanwhile, vibration of a machine set is absorbed, after wind blows the blades, the blades rotate, at the moment, wind energy can be converted into mechanical energy, then the mechanical energy is converted into electric kinetic energy, and power generation is achieved.
Further, the cover plate assembly 100 may further include a platform cover plate 120 and a driving device 130.
Specifically, the wind turbine generator system may further include a wind turbine platform 110, and the wind turbine platform 110 may be disposed in a wind turbine tower, and multiple layers of wind turbine platforms 110 are disposed in the wind turbine tower. In the height direction of the wind turbine tower, multiple layers of wind turbine platforms 110 are arranged in sequence, and each layer of wind turbine platform 110 has a platform cover plate 120. Moreover, each layer of the fan platform 110 is provided with an avoidance channel 111, and the avoidance channel 111 is used for the rail 180 to pass through, so that when a crawler or an operator needs to reach a target position, the crawler or the operator can move along the rail 180, pass through the avoidance channel 111 of the fan platform 110, and reach the target position.
As shown in fig. 1 and 6, the platform cover 120 is connected to the fan platform 110. For example, the platform cover 120 may be pivotally connected to the fan platform 110 by hinges. The driving device 130 is connected to the fan platform 110. That is, the driving device 130 is disposed on the fan platform 110, and the fan platform 110 provides an installation location and an installation space for the driving device 130.
Further, as shown in fig. 3 and 5, the driving device 130 includes a gear assembly 140, a driving motor 150, a link assembly 160, and a main control panel 170. The main control panel 170 is in communication connection with the driving motor 150, and the main control panel 170 is adapted to control the driving motor 150 to rotate forward or backward. The term "communication connection" is understood here to mean a wired connection or a wireless connection. That is, the main control board 170 may transmit the control command to the driving motor 150 in the form of a wired signal; of course, the main control board 170 may also transmit the control command to the driving motor 150 in the form of a wireless signal, so that the driving motor 150 may rotate forward or backward according to the control command.
As can be seen from fig. 3, the driving motor 150 is connected to the platform cover 120 through the gear assembly 140 and the link assembly 160, which are connected in sequence, so as to drive the platform cover 120 to move. Specifically, the driving motor 150 is connected to the gear assembly 140, and the driving motor 150 is used for driving the gear assembly 140 to move. The gear assembly 140 is connected to one end of the link assembly 160, and the other end of the link assembly 160 is connected to the platform cover 120, so that when the gear assembly 140 drives the link assembly 160 to move, the link assembly 160 can drive the platform cover 120 to move. Further, the escape passage 111 may be opened or closed during the movement of the platform cover 120. In this way, the motion of the driving motor 150 may be transmitted to the platform cover 120.
Further, as shown in fig. 2, the platform cover 120 is in a closed state for closing the escape passage 111; as shown in fig. 7, the platform cover 120 is in an open state to open the escape passage 111.
When the main control panel 170 transmits a control instruction for opening the avoidance channel 111, the driving motor 150 rotates forward and drives the gear assembly 140 to transmit along the first direction, the gear assembly 140 drives the connecting rod assembly 160 to move, and the connecting rod assembly 160 can drive the platform cover plate 120 to perform an opening action, so that the platform cover plate 120 can open the avoidance channel 111; when the main control panel 170 transmits a control command for closing the avoidance channel 111, the driving motor 150 rotates reversely and drives the gear assembly 140 to drive along a second direction, the second direction is opposite to the first direction, the gear assembly 140 drives the link assembly 160 to move, and the link assembly 160 can drive the platform cover 120 to perform a closing action, so that the platform cover 120 can close the avoidance channel 111.
According to the cover plate assembly 100 of the embodiment of the invention, the platform cover plate 120 is driven to move by the gear assembly 140 and the connecting rod assembly 160, so that the movement can be smoothly transmitted between the driving motor 150 and the platform cover plate 120, and the platform cover plate 120 can be flexibly switched between the opening state and the closing state, thereby not only improving the automation degree of the wind generating set, but also improving the flexibility of switching the state of the platform cover plate 120, reducing the labor intensity of operators and meeting the operation requirements of the operators.
According to some embodiments of the present invention, as shown in fig. 3 and 5, the driving device 130 may further include a base 171, a motor bracket 151, and a gear bracket 145. Wherein, the base 171 is fixedly connected with the fan platform 110, and the main control board 170 is fixedly connected with the base 171. It is understood that the fan platform 110 may provide mounting locations for the base 171, and the base 171 may provide mounting locations for the main control panel 170, the motor bracket 151, and the gear bracket 145.
Referring to fig. 3 and 5, the motor bracket 151 is fixedly connected to the base 171, the driving motor 150 is fixedly connected to the motor bracket 151, the gear bracket 145 is fixedly connected to the base 171, the gear bracket 145 is spaced apart from the motor bracket 151, and the gear assembly 140 is disposed on the gear bracket 145. It will be appreciated that the structure of the cover plate assembly 100 can be simplified by providing the motor bracket 151 and the gear bracket 145, and providing the gear assembly 140 on the gear bracket 145 and the driving motor 150 on the motor bracket 151, so that the driving unit 130 can be modularized to facilitate assembly of the driving unit 130. Further, referring to fig. 4, the lower end edge of the motor bracket 151 is bent to form a bracket flange 1511, and the bracket flange 1511 may be fixedly connected to the base 171 by a screw, so that the connection stability between the motor bracket 151 and the base 171 can be improved.
In addition, by disposing the motor bracket 151 and the gear bracket 145 on the base 171 and disposing the gear assembly 140 on the gear bracket 145 and disposing the driving motor 150 on the motor bracket 151, the driving motor 150 and the gear assembly 140 do not need to be directly mounted on the base 171 and both can be spaced apart from the base 171, whereby the space on one side of the base 171 can be effectively utilized, so that the spatial layout of the driving device 130 can be optimized, the structural compactness can be improved, and the volume of the driving device 130 can be reduced.
In some embodiments, referring to fig. 3 and 5, the main control board 170 and the base 171 have a gap 173 therebetween. It should be noted that a plurality of electrical components may be disposed on the main control board 170, wherein at least some of the electrical components will release heat during operation, and the gap 173 is disposed to facilitate heat dissipation of the main control board 170. In addition, it should be noted that due to the particularity of the wind turbine generator system, the wind turbine generator system is often in vibration, shaking, and other conditions, such as when the driving device 130 drives the platform cover plate 120 to move, or when a crawler or an operator passes through the wind turbine platform 110, or when the wind turbine platform 110 is in a harsh environment. When the fan platform 110 vibrates or shakes, the gap 173 between the main control board 170 and the base 171 can well block the transmission of the vibration, so that the vibration can be prevented from being transmitted to the main control board 170, and the main control board 170 is protected.
In view of the stability of the assembly of the main control board 170, in some examples, as shown in fig. 5, a plurality of spaced support columns 172 may also be disposed within the gap 173, each support column 172 being connected between the main control board 170 and the base 171. It is understood that the supporting column 172 may be supported between the main control board 170 and the base 171, thereby functioning to support the main control board 170 to improve the assembling stability of the main control board 170.
Further, the supporting column 172 may be a cylinder, and one end of the supporting column 172 and the base 171 may be connected by a screw, or a welding process may be used to weld one end of the supporting column 172 and the base 171 together. The other end of the supporting column 172 may be fixedly connected to the main control board 170 by a screw, for example, the screw passes through the main control board 170 and is screwed with the other end of the supporting column 172.
Furthermore, a buffer rubber pad can be arranged between the end faces of the free ends of the main control board 170 and the support columns 172, so that the connection stability and reliability between the main control board 170 and the support columns 172 can be improved, and the vibration transmitted from the base 171 can be absorbed by using the vibration absorption function of the buffer rubber pad, so that the vibration absorption effect is achieved, and the main control board 170 can be protected.
According to some embodiments of the present invention, as shown in fig. 3, 4, gear bracket 145 includes a first bracket 146 and a second bracket 147 that are spaced apart. The first bracket 146 and the second bracket 147 are spaced apart, and the lower end of the first bracket 146 has a first folding edge 1461, and the first folding edge 1461 is fixedly connected to the base 171 by a plurality of screws. Similarly, the lower end of the second bracket 147 has a second flange 1471, and the second flange is fixedly connected to the base 171 by a plurality of screws. Thereby, the connection stability between the first bracket 146 and the base 171 and the connection stability between the second bracket 147 and the base 171 can be improved.
In some embodiments, the gear assembly 140 may be a reduction gear set, so that the platform cover 120 can move smoothly when switching between the open state and the closed state, and interference or collision between the platform cover 120 and other components can be prevented, thereby improving the smoothness of the movement of the platform cover 120.
Further, referring to fig. 4, the gear assembly 140 may include: a primary reduction gear set 141, a secondary reduction gear set 142, an angle sensor 149, and a damper.
Specifically, the first-stage reduction gear set 141 is connected to the driving motor 150 and disposed on the first bracket 146, the second-stage reduction gear set 142 is engaged with the first-stage reduction gear set 141, and the second-stage reduction gear set 142 is disposed on the second bracket 147 and connected to the link assembly 160. After the rotational speed of driving motor 150 passes through first-stage reduction gear set 141, the first-stage speed reduction can be carried out, and after passing through second-stage reduction gear set 142, the rotational speed further reduces, and from this, the second-stage speed reduction can be realized, thereby preventing that platform cover plate 120 from moving too fast and appearing collision and damage.
As shown in fig. 5, the motor bracket 151, the first bracket 146, and the second bracket 147 are sequentially arranged at intervals and are parallel to each other. Therefore, the internal space of the driving device 130 can be further optimized, and the structure of the driving device 130 is more compact and reasonable. In the example shown in fig. 5, a first support rod 152 is connected between the motor bracket 151 and the first bracket 146, and the first support rod 152 can improve the stability between the motor bracket 151 and the first bracket 146, so as to prevent the driving device 130 from shaking the motor bracket 151 and the first bracket 146 due to vibration, and further prevent the components arranged on the brackets from colliding. Further, as shown in fig. 5, a second support bar 153 is connected between the first bracket 146 and the second bracket 147. The second support bar 153 may also function as a support to improve the stability between the first support 146 and the second support 147.
As shown in fig. 5, the angle sensor 149 is provided on the first bracket 146. The angular velocity sensor may be used to detect the rotation angle of the pivot 143 at the output end of the secondary reduction gear set 142, so that the motion state of the deck plate 120 may be monitored. In addition, the first bracket 146 may provide a mounting position for the angle sensor 149, which facilitates the angle sensor 149 to monitor the rotation state of the platform cover 120, and also prevents other components of the cover assembly from interfering with the platform cover 120. Further, as shown in fig. 5, an angle sensor 149 may be provided on a side of the first bracket 146 facing away from the second bracket 147.
In some embodiments, the damper is disposed at the pivot shaft 143 for increasing the rotational damping of the pivot shaft 143, so as to reduce the rotational speed of the pivot shaft 143 and avoid the occurrence of impact due to too fast rotational speed. It should be noted that, when the platform cover 120 performs the opening action, in the last period of the opening action to be finished, the platform cover 120 needs to rapidly reduce the movement speed to avoid the impact, and the damper is provided to rapidly reduce the movement speed of the platform cover 120 before the opening action is completed, until the movement speed of the platform cover 120 is reduced to zero when the platform cover 120 is in the fully opened position, so as to reduce the impact of the inertia of the platform cover 120 on the driving device 130. Similarly, when the platform cover 120 performs the closing action, the platform cover 120 needs to rapidly reduce the moving speed during the last period of the closing action, and the damper is provided to rapidly reduce the moving speed of the platform cover 120 before the closing action is completed, until the moving speed of the platform cover 120 is reduced to zero when the platform cover 120 is in the fully closed position, so as to reduce the impact of inertia of the platform cover 120.
According to some embodiments of the present invention, as shown in fig. 2 and 5, the connecting rod assembly 160 may include: a first link 161 and a second link 162. One end of the first link 161 is connected to the gear assembly 140, the first link 161 is a straight rod, one end of the second link 162 is pivotally connected to the other end of the first link 161, and the other end of the second link 162 is hinged to the platform cover 120.
Thus, the gear assembly 140 can drive the first link 161 to swing, the first link 161 drives the second link 162 to move, and the second link 162 can drive the platform cover 120 to perform an opening or closing action. Further, as shown in fig. 5, the middle portion of the second link 162 has a bent portion 163. It should be noted that the bending portion 163 can change the extending direction of the second link 162, so as to facilitate the end of the second link 162 away from the first link 161 to move to the target position. When the second link 162 moves the platform cover 120, the platform cover 120 can be switched between different target positions, and the end of the second link 162 away from the first link 161 can reach the target position more easily.

A retaining cap 164 covers the outer annular surface of end flange bearing 148.
On one hand, the structural characteristics of the end flange bearing 148 can be utilized to increase the contact area between the first link 161 and the second bracket 147, so that the first link 161 can be stably connected to the second bracket 147; on the other hand, in the process of motion transmission, when the pivot shaft 143 rotates, the first link 161 needs to rotate along with the pivot shaft 143, and by designing the end flange bearing 148 and the positioning cover 164 covering the end flange bearing 148, the positioning cover 164 can rotate around the end flange bearing 148, so that the link assembly 160 can rotate along with the gear assembly 140 under the condition that the requirement that the link assembly 160 is assembled with the gear bracket 145 is met, and therefore the transmission flexibility between the gear assembly 140 and the link assembly 160 can be improved. In addition, in some embodiments, end flange bearings 148 may be installed at both ends of the pivot shaft 143, such that the end flange bearings 148 at both ends of the pivot shaft 143 serve as an axial limit for the pivot shaft 143.
In order to enable the second link 162 and the pivot shaft 143 to rotate synchronously, in some embodiments, as shown in fig. 3 and 4, the positioning cover 164 has a positioning groove 165 therein, and the positioning boss 144 is embedded in the positioning groove 165, so that the positioning boss 144 can perform a key connection function when being fitted in the positioning groove 165, thereby enabling the positioning boss 144 and the positioning cover 164 to rotate synchronously. Further, the positioning cover 164 is fixedly connected to the pivot shaft 143 by a bolt 166. Thus, the linkage requirement between the link assembly 160 and the gear assembly 140 can be satisfied through a simple assembly relationship.
According to some embodiments of the present invention, as shown in fig. 3, the cover plate assembly 100 may further include a shield 174, and the shield 174 may be disposed to cover the driving device 130, whereby the driving device 130 may be protected by the shield 174. Further, as shown in fig. 3, the shield 174 has a mounting hole 175, and one end of the link assembly 160 is inserted through the mounting hole 175 to be coupled with the gear assembly 140. Thereby facilitating connection of the linkage assembly 160 to the gear assembly 140.
Further, as can be appreciated in conjunction with fig. 3, the shield 174 may include a first side panel 176, a second side panel 177, and a cover panel 178.

The cover plate 178 is a U-shaped cylindrical plate, the base 171 can be used for sealing the opening of the U-shaped structure, and the first side plate 176 and the second side plate 177 are used for sealing the ends of the two ends of the cylindrical structure. That is, the inner space of the U-shaped cover plate 178 can be used as a space for accommodating the driving device 130, and the base 171, the first side plate 176 and the second side plate 177 can be used for blocking three sides of the U-shaped column structure to form a closed space, so as to achieve the purpose of protecting the driving device 130.
According to the embodiment of the invention, the wind generating set comprises: a fan platform 110, a track 180, a first door magnet assembly 181, a second door magnet assembly 182, and a cover plate assembly 100 as described above.
Specifically, the rail 180 is disposed through the escape passage 111 of the fan platform 110. The wind turbine platform 110 may be disposed in a wind turbine tower, and in the height direction of the wind turbine tower, a plurality of layers of wind turbine platforms 110 are disposed in the wind turbine tower, and each layer of wind turbine platform 110 has a platform cover plate 120. Each layer of fan platform 110 has an escape passage 111, and the escape passage 111 is penetrated by the rail 180. Thus, when a crawler or operator desires to reach a target location, the crawler or operator may move along the track 180, through the escape path 111 of the wind turbine platform 110, and to reach the target location.
Both the first door magnetic assembly 181 and the second door magnetic assembly 182 can be used for detecting the moving direction of the dynamic object, and both the first door magnetic assembly 181 and the second door magnetic assembly 182 can be arranged on the track 180. The first door assembly 181 is located on one side of the fan platform 110 and the second door assembly 182 is located on the other side of the fan platform 110. The first door magnet assembly 181 and the second door magnet assembly 182 are both communicatively coupled to the main control panel 170 of the cover assembly 100.
It should be noted that, the first door magnetic assembly 181 and the second door magnetic assembly 182 may be used in cooperation, for example, when the first door magnetic assembly 181 detects that a dynamic target approaches the platform cover plate 120, the first door magnetic assembly 181 is triggered, the main control board 170 receives a trigger signal and then sends a control instruction for controlling the driving motor 150 to rotate forward, the driving motor 150 rotates forward, and the connecting rod assembly 160 can drive the platform cover plate 120 to perform an opening action through the transmission function of the gear assembly 140 and the connecting rod assembly 160; when the second door magnet assembly 182 detects that a dynamic target leaves the platform cover plate 120, the second door magnet assembly 182 is triggered, the main control board 170 receives a trigger signal and then sends a control instruction for controlling the driving motor 150 to rotate reversely, the driving motor 150 rotates reversely, and the connecting rod assembly 160 can drive the platform cover plate 120 to close through the transmission function of the gear assembly 140 and the connecting rod assembly 160.
In some examples, the first magnetic gate assembly 181 may include two magnetic gate detecting members, and the two magnetic gate detecting members may be spaced apart along the extending direction of the track 180, so that the moving direction of the dynamic object may be detected according to the detection information of the two magnetic gate detecting members. Similarly, the second door magnet assembly 182 may also include two door magnet detecting members, and the two door magnet detecting members may be spaced apart along the extending direction of the track 180, so that the moving direction of the dynamic object may be detected according to the detection information of the two door magnet detecting members.
It should be noted that the first door magnetic assembly 181 and the second door magnetic assembly 182 are disposed to enable the platform cover 120 to be automatically opened or closed. Therefore, the automation degree of the wind generating set can be improved. In addition, in order to increase the control mode diversity of the wind turbine generator system, referring to fig. 1 and 6, the wind turbine generator system may further include a manual switch assembly. The manual switch assembly is communicatively connected to the main control panel 170. Thus, when the manual switch assembly is triggered, a signal to open the platform cover 120 or a signal to close the platform cover 120 may be transmitted to the main control board 170.
For example, when an operator operates on the fan platform 110, in order to ensure the personal safety of the operator, the platform cover 120 needs to be closed, the manual switch assembly may be manually triggered at this time, and after receiving information sent by the manual switch assembly, the main control board 170 sends a control instruction for controlling the driving motor 150 to rotate reversely, so that the platform cover 120 may be switched to a closed state. For another example, when the wind turbine generator system is in the power-off state and the platform cover 120 is in the open state, the manual switch component sends a closing signal for closing the platform cover 120, so as to control the platform cover 120 to switch to the closed state.
Here, the kind of the manual switch assembly is not particularly limited, and for example, the manual switch assembly may be a mechanical button, a touch button, a mobile terminal, a remote controller, or the like. In order to facilitate the control of the manual switch assembly by the operator, the manual switch assembly may be multiple, for example, one of the manual switch assemblies is a first switch component 183, and the first switch component 183 may be disposed on one side of the platform cover 120 and mounted on the rail 180; for another example, one of the manual switch assemblies is a second switch 184, and the second switch 184 may be disposed on the other side of the platform cover 120 and mounted on the rail 180; for another example, a plurality of manual switch assemblies may be disposed on one side of the platform cover 120, and the manual switch assemblies may be distributed at intervals along the track 180, or may be disposed at any position of the fan platform 110.
According to the wind generating set of the embodiment of the invention, the platform cover plate 120 is driven to move by the gear assembly 140 and the connecting rod assembly 160, so that the movement can be smoothly transmitted between the driving motor 150 and the platform cover plate 120, and the platform cover plate 120 can be flexibly switched between the opening state and the closing state, thereby not only improving the automatic control degree of the wind generating set, but also improving the flexibility of switching the state of the platform cover plate 120 and meeting the operation requirements of operators.
