Description

Technical Field

[0001] The utility model relates to the technical field of motors, and specifically to a motor for controlling the opening and closing of a valve. Background Art

[0002] A motor, commonly known as a motor, is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. Motors are widely used and applied in various fields, and the use of motors has also brought many conveniences to people's lives.

[0003] A motor can convert electrical energy into mechanical energy. Through the magnetic device inside the motor, the conversion of the two types of energy is realized. Motors can be used to make fans, switches, driving structures of trams, etc. However, in actual use, the motor is not overly protected. When the motor is used to control the opening and closing of a valve, if the valve is locked due to some situation, such as sundries jamming the switch, the valve rusting, etc., resulting in the motor shaft being unable to rotate, the process of converting electrical energy into mechanical energy stops, and electrical energy accumulates, thus causing energy overload. As a result, the internal coil of the motor will be directly burned out, finally leading to the damage of the motor.

[0004] In view of the above problems, we provide a motor for controlling the opening and closing of a valve to solve the problems mentioned above. Content of the Utility Model

Specific implementation manners

[0022] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0023] In one embodiment, as Figures 1 - 3 shown, a motor for controlling the opening and closing of a valve includes a motor body 100. One side of the motor body 100 penetrates and outputs a rotating shaft 106. The rotating shaft 106 is used to provide a rotating power for subsequent connecting structures. A first fixing plate 101 is vertically installed at the horizontal middle position of the rotating shaft 106 for supporting and fixing it. A cooling component 200 is installed outside the motor body 100. The cooling component 200 is used to cool the inside of the motor body 100. The output end of the rotating shaft 106 is connected to a valve drive component 400 for controlling the valve through an overload protection component 300. The overload protection component 300 is used to provide overload protection for the motor body 100.

[0024] In one embodiment, as Figure 1As shown, the cooling component 200 includes a heat dissipation sleeve 201, a water pump 202, a liquid storage tank 203, a liquid supply pipe 204, an infusion pipe 205 and a liquid return pipe 206. The heat dissipation sleeve 201 is installed around the outer surface of the motor body 100. The heat dissipation sleeve 201 is used to fill the coolant to cool the motor body 100. The filling method of the heat dissipation sleeve 201 with the coolant is from bottom to top. One side of the bottom of the heat dissipation sleeve 201 is provided with an infusion pipe 205 in a penetrating manner, and the top of the heat dissipation sleeve 201 is provided with a liquid return pipe 206 in a penetrating manner. The water pump 202 is connected to the heat dissipation sleeve 201 through the infusion pipe 205. The liquid storage tank 203 is connected to the heat dissipation sleeve 201 through the liquid return pipe 206. A liquid supply pipe 204 is also connected between the liquid storage tank 203 and the water pump 202. The liquid storage tank 203 and the water pump 202 are installed near the motor body 100. Under the action of the water pump 202, the coolant in the liquid storage tank 203 enters the water pump 202 through the liquid supply pipe 204, and then enters the heat dissipation sleeve 201 through the infusion pipe 205. When the heat dissipation sleeve 201 is filled with the coolant, it returns to the liquid storage tank 203 through the liquid return pipe 206, thus forming a circulating flow of the coolant, and further continuously cooling the motor body 100.

[0025] In one embodiment, as Figures 1 - 3As shown, the overload protection component 300 includes a first transmission gear 301, a second transmission gear 302, a sliding shaft 303, a limiting mechanism, an elastic mechanism, a sliding sleeve 306, and a first connecting shaft 308. The left end of the first transmission gear 301 is fixedly connected to the right end of the rotating shaft 106. The first transmission gear 301 rotates synchronously with the rotating shaft 106. The right end of the first transmission gear 301 is meshed with the second transmission gear 302. The second transmission gear 302 is used to receive the rotational power from the first transmission gear 301. The second transmission gear 302 is connected to the sliding shaft 303 through the first connecting shaft 308. An elastic mechanism is provided outside the sliding shaft 303. The elastic mechanism is a compression spring 305. A sliding sleeve 306 is also sleeved on the right end of the sliding shaft 303. The compression spring 305 is wound around the sliding shaft 303 and is located between the first connecting shaft 308 and the sliding sleeve 306 and provides a tension force for both of them. A plurality of limiting mechanisms are provided between the sliding shaft 303 and the sliding sleeve 306. The limiting mechanisms are anti-rotation limiting keys 304 and limiting grooves 307. There are a plurality of anti-rotation limiting keys 304 and they are installed around the sliding shaft 303. The limiting grooves 307 are opened on the inner side of the sliding sleeve 306 corresponding to the positions of the anti-rotation limiting keys 304. Under the cooperative action of the anti-rotation limiting keys 304 and the limiting grooves 307, the sliding shaft 303 can only slide in the sliding sleeve 306 and cannot rotate. A second fixing plate 102 is vertically installed on the outside of the sliding sleeve 306 to support and fix it. The specific principle of the overload protection component 300 is as follows: When the subsequent device gets stuck in rotation, causing the second transmission gear 302 unable to rotate, at this time, the force between the first transmission gear 301 and the second transmission gear 302 is too large, so that the second transmission gear 302 drives the first connecting shaft 308 to move to the right. At the same time, the first connecting shaft 308 compresses the compression spring 305 and drives the sliding shaft 303 and the anti-rotation limiting keys 304 to slide in the sliding sleeve 306 until the first transmission gear 301 and the second transmission gear 302 are separated, so that the rotating shaft 106 can drive the first transmission gear 301 to continue rotating, preventing overload inside the motor body 100.

[0026] In one embodiment, as Figure 1 and Figure 3As shown, the valve drive assembly 400 includes a worm 401 and a worm gear 402. The worm 401 is fixedly connected to the right end of the sliding sleeve 306. A third fixing plate 103 is vertically installed on the outer side of the right end of the worm 401 for supporting and fixing it. A worm gear 402 is meshed and connected above the worm 401. The inner side of the worm gear 402 is fixedly connected to a second connecting shaft 501. The worm gear 402 and the worm 401 are used to transfer the rotational power on the rotating shaft 106 to the second connecting shaft 501. A fourth fixing plate 104 is vertically installed on the outer side of the second connecting shaft 501 for supporting and fixing it. Both ends of the fourth fixing plate 104 are fixedly connected to the tops of the second fixing plate 102 and the third fixing plate 103. The output end of the second connecting shaft 501 is fixedly connected to a valve stem 502. The other end of the valve stem 502 is fixedly connected to a butterfly valve 503. The worm gear 402 and the worm 401 drive the butterfly valve 503 by converting the rotational power on the rotating shaft 106. And the worm 401 and the worm gear 402 have self-locking property, specifically manifested as the worm 401 can drive the worm gear 402 to rotate, but the worm gear 402 cannot drive the worm 401 to rotate. Utilizing this property to lock the butterfly valve 503.

[0027] During use, the motor body 100 starts to operate. At this time, the externally installed cooling component 200 also starts to operate. Under the action of the water pump 202, the coolant in the liquid storage tank 203 enters the water pump 202 through the liquid supply pipe 204, and then enters the heat dissipation sleeve 201 through the liquid infusion pipe 205. When the heat dissipation sleeve 201 is filled with coolant, it returns to the liquid storage tank 203 through the liquid return pipe 206, thus forming a circulating flow of coolant, and then continuously cooling the motor body 100. A rotating shaft 106 is output on one side of the motor body 100. The rotating shaft 106 drives the subsequent overload protection component 300 and valve drive component 400 to operate. The valve drive component 400 drives and controls the butterfly valve 503 by converting the rotational power on the rotating shaft 106 through the worm gear 402 and the worm 401, and then locks the butterfly valve 503 through the self-locking function of the worm 401 and the worm gear 402. When the valve is locked due to reasons such as rust and foreign matter jamming, the overload protection function of the overload protection component 200 is triggered. At this time, since the valve is locked and cannot rotate, the second transmission gear 302 cannot rotate either. At the same time, the force between the first transmission gear 301 and the second transmission gear 302 becomes larger, so that the second transmission gear 302 drives the first connecting shaft 308 to move to the right. At the same time, the first connecting shaft 308 compresses the compression spring 305 and drives the sliding shaft 303 and the anti-rotation limit key 304 to slide in the sliding sleeve 306 until the first transmission gear 301 and the second transmission gear 302 are separated, so that the rotating shaft 106 can drive the first transmission gear 301 to continue rotating, preventing overload inside the motor body 100.

[0028] The above embodiment discloses a motor for controlling the opening and closing of a valve, in which an overload protection component provides overload protection for the motor. Specifically, when the controlled valve is locked, the rotating shaft can continue to rotate under the action of the overload protection component, avoiding the occurrence of energy overload inside the motor, effectively preventing the damage of the motor, and solving the problems raised in the above background art.

[0029] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
