Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

As shown in fig. 1 and 2, an embodiment of the present invention provides a motor apparatus including a motor body 10, a cooling assembly, a flow pipe 20, and a spray head 30. The cooling assembly is used for providing cooling fluid; the circulating pipe 20 is annular, the circulating pipe 20 is sleeved on the outer side of the motor body 10, the circulating pipe 20 is provided with an inlet and an outlet which are oppositely arranged, and the cooling assembly is communicated with an inlet 21 of the circulating pipe; the spray head 30 is disposed at the outlet 22 of the flow pipe, the spray head 30 communicates with the flow pipe 20, and a nozzle on the spray head 30 is disposed toward the motor body 10. The shape of the circulating pipe 20 is matched with the outer peripheral surface of the motor body 10, so that the circulating pipe 20 is stably sleeved on the motor body 10. The nozzle may be a high pressure nozzle, so that the cooling fluid flows toward the motor body 10 at a high speed, thereby further improving the heat dissipation effect. Alternatively, the cooling fluid may be in a liquid or gaseous state. The cooling fluid may be in a normal or low temperature state. In this embodiment, the cooling assembly may be designed as a compressed air pipeline 60 disposed in a mine, and a connecting pipe may be disposed between the compressed air pipeline 60 and the inlet 21 of the circulating pipe to communicate the compressed air pipeline 60 and the circulating pipe 20, so that the motor body 10 is cooled by the cold air provided by the compressed air pipeline 60.

By applying the technical scheme of the utility model, the circulation pipe 20 is sleeved on the outer side of the motor body 10, the cooling assembly is communicated with the inlet 21 of the circulation pipe, the spray head 30 is arranged at the outlet 22 of the circulation pipe, the spray head 30 is communicated with the circulation pipe 20, cooling fluid flowing out of the cooling assembly flows out from the nozzle of the spray head 30 towards the motor body 10 through the circulation pipe 20, so that the motor body 10 is cooled through the cooling fluid, and meanwhile, the temperature of the environment where the motor body 10 is located can be reduced, thereby reducing the failure rate of each part of the motor body 10 and prolonging the service life of the motor body 10. In addition, the technical scheme has the advantages of simple structure, low manufacturing cost, convenience in installation and the like.

In this embodiment, the number of the outlets 22 of the circulation pipes is plural, and the outlets 22 of the plural circulation pipes are uniformly distributed on the sidewall of the circulation pipe 20; the motor means comprises a plurality of spray heads 30, which spray heads 30 are arranged in one-to-one correspondence with the outlets 22 of the flow-through ducts. With the above structure, the cooling fluid can uniformly flow around the motor body 10, so that the motor body 10 can be cooled better, and the hot air around the motor body 10 can be blown away better.

Specifically, the motor body 10 has a first end and a second end which are oppositely arranged, the first end 11 of the motor body is a driving end, the circulation pipe 20 is sleeved at the second end 12 of the motor body, and the nozzle 30 is arranged at one side of the circulation pipe 20 close to the first end 11 of the motor body. The first end 11 of the motor body generates more heat, and by adopting the structure, the first end 11 of the motor body can be effectively cooled, and hot air around the first end 11 of the motor body can be blown away to a greater extent. In actual use, the motor is placed in the chamber 80 of the mine, the first end 11 of the motor body is arranged on one side, close to the roadway 70, of the chamber 80, the spray head 30 is arranged on one side, far away from the roadway 70, of the chamber 80, cooling fluid sprayed by the spray head 30 can flow towards the roadway 70, and then hot air in the chamber 80 is driven into the roadway 70 through the cooling fluid, so that the temperature in the chamber 80 is effectively reduced, and the motor body 10 is prevented from being in a high-temperature state for a long time.

In particular, the spray head 30 has a conical structure, the diameter of the end of the spray head 30 connected to the flow-through pipe 20 gradually decreasing towards the nozzle. The spray head 30 is tapered so that the cooling fluid flows through the spray nozzle at an increased velocity, thereby enabling the cooling fluid to better drive the flow of hot air around the motor body 10.

In the embodiment, the axis of the nozzle 30 intersects with the axis of the flow pipe 20 at an included angle α, which is 50 ° α 10 °. If α is smaller than 10 °, the cooling fluid sprayed from the spray head 30 cannot or less flows to the motor body 10, and the motor body 10 cannot be cooled; if α is greater than 50 °, the cooling fluid ejected from the ejection head 30 has a slower flow speed in the direction toward the first end 11 of the motor body, thereby causing the cooling fluid not to drive out the hot air around the motor body 10 well. Therefore, the setting of 50 ° α ≧ 10 ° enables the cooling fluid ejected from the head 30 to flow toward the motor body 10 and the flow speed of the cooling fluid toward the first end 11 of the motor body to be fast, thereby enabling the cooling effect to be improved.

Specifically, the circulation pipes 20 are circular, the included angle between the central points of the outlets 22 of two adjacent circulation pipes and the connecting line of the central points of the circulation pipes 20 is beta, and the included angle is not less than 90 degrees and not less than 12 degrees. If beta is smaller than 12 degrees, the number of the outlets 22 of the circulating pipes is too large, the processing difficulty is high, and the installation difficulty of the spray head 30 is increased; if β is greater than 90 °, the number of outlets 22 of the flow-through duct is too small, so that the flow-through duct 20 discharges less cooling fluid, and the hot air around the motor body 10 is not well dissipated.

In this embodiment, the motor device further includes a connection pipe 40, one end of the connection pipe 40 is connected to the inlet 21 of the circulation pipe, and the other end of the connection pipe 40 is connected to the cooling unit. By providing the connecting pipe 40, the communication of the flow-through pipe 20 with the cooling module is facilitated.

In the present embodiment, the connection pipe 40 is provided with a control valve 50. The control valve 50 is used to control the cooling module to increase the cooling fluid to the flow-through pipe 20 or to control the cooling module to stop the supply of the cooling fluid to the flow-through pipe 20.

In this embodiment, a connection is provided between the outlet 22 of the flow-through pipe and the spray head 30. Through setting up the joint, can conveniently connect runner pipe 20 and shower nozzle 30, and then can improve whole motor device's packaging efficiency. In particular, the nipple may be provided with a screw structure to screw-couple the nipple to the flow-through pipe 20 and the spray head 30, respectively.
