Description

Technical Field

[0001] This invention belongs to the field of electric motor technology, specifically relating to a waterproof three-phase asynchronous motor for use in steel mill roller conveyors. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by an energized coil to act on a rotor, creating a magnetoelectric torque. A three-phase asynchronous motor is a type of induction motor that is powered by three-phase AC current (120 degrees phase difference) simultaneously connected to a 380V circuit. Because the rotor and stator rotating magnetic fields of a three-phase asynchronous motor rotate in the same direction but at different speeds, there is slip, hence the name three-phase asynchronous motor. The rotor speed of a three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor windings generate electromotive force and current due to the relative motion between them and the magnetic field, and interact with the magnetic field to produce electromagnetic torque, thus achieving energy conversion. Compared with a single-phase asynchronous motor, a three-phase asynchronous motor has better operating performance and can save various materials.

[0003] In steel mill roller conveyors, the ground is difficult to keep flat. Although the existing three-phase asynchronous motors have basic waterproof performance, when the rainfall is too heavy and the ground accumulates water to a certain extent, the existing three-phase asynchronous motors are not enough to cope with the soaking of rainwater. Water can easily enter the motor's interior, causing internal parts to rust and making the motor easily damaged, thus reducing the service life of the three-phase asynchronous motor.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a waterproof three-phase asynchronous motor for steel mill roller conveyors. Summary of the Invention

[0005] The purpose of this invention is to provide a waterproof three-phase asynchronous motor for steel mill roller conveyors, in order to solve the problem that existing three-phase asynchronous motors are unable to withstand rainwater immersion, and that water can easily enter the motor's interior, causing damage to the motor.

[0006] To achieve the above objectives, an embodiment of the present invention provides the following technical solution:

[0007] A waterproof three-phase asynchronous motor for steel mill roller conveyors includes a motor body, waterproof components, a water-sweeping mechanism, and a heat dissipation mechanism;

[0008] The motor body is used to convert electrical energy into mechanical energy, and a transmission rod is provided on the motor body;

[0009] The waterproof component is installed on the outside of the motor body to protect the motor body and reduce the probability of parts corrosion caused by rainwater. The waterproof component includes a waterproof bucket with an insertion hole on the inner side wall. A top cover is hinged to the waterproof bucket, and a rubber ring is installed on the top cover. A sleeve is inserted into the rubber ring to protect the transmission rod. A strip-shaped opening is cut on the top cover, and a pair of sliding grooves are cut on a pair of side walls of the strip-shaped opening. A sliding block is installed in the strip-shaped opening, and a sliding element is provided on a pair of side walls of the sliding block. The sliding element is slidably connected in the sliding groove. An insert is connected to the side wall of the sliding block, and the insert penetrates the side wall of the top cover so that the insert can move with the sliding block. The insert is correspondingly set with the insertion hole so that the top cover can be fixed to the side wall of the waterproof bucket. A winding stator is filled in the waterproof bucket to generate a rotating magnetic field.

[0010] The water-sweeping mechanism is installed at the bottom of the waterproof bucket and is used for cleaning up accumulated water.

[0012] Furthermore, a nylon buckle is installed on the inner side wall of the sleeve, and a drying cotton is installed on the nylon buckle, so that the drying cotton can be replaced. The drying cotton is used to absorb moisture inside the sleeve. The raw material of the drying cotton is a blend of polyester fiber and viscose fiber, which has excellent water absorption.

[0013] Furthermore, the top cover is provided with a handle, which is welded to the top cover, improving the installation firmness of the handle. The handle is provided with anti-slip texture to facilitate the user's use of the top cover.

[0014] Furthermore, the waterproof bucket has a pull ring on its side wall, and the outer surface of the pull ring has anti-slip texture to facilitate user use. The pull ring is made of thermosetting plastic and has excellent bending resistance.

A mounting ring is installed on the outer surface of the rotating block, and a base is installed at the bottom of the rotating block.

[0016] Furthermore, the mounting ring is made of hard rubber, which has high strength and a certain degree of ductility, and multiple water-sweeping components are evenly distributed on the outer surface of the mounting ring for cleaning up accumulated water.

[0017] Furthermore, the water sweeping mechanism includes a water collection tank, which is located on one side wall of the waterproof bucket. A pair of connecting pipes are provided on one side wall of the water collection tank, which passes through the waterproof bucket. The other end of the connecting pipe is connected to a heat dissipation component. The connecting pipe guides the rainwater in the water collection tank into the heat dissipation component. The heat dissipation component is in contact with the motor body and absorbs the heat from the outside of the motor body through the rainwater.

[0018] Furthermore, the water collection tank is equipped with a funnel to receive more rainwater, and a filter screen is installed at the bottom of the funnel to filter out particulate matter such as mud, sand and gravel. The mesh size of the filter screen is 500 mesh.

[0019] Furthermore, the heat sink is cylindrical and made of copper, which has excellent heat transfer performance.

[0031] The present invention will be described in detail below with reference to the various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present invention.

[0032] The present invention discloses a waterproof three-phase asynchronous motor for a steel mill roller path. Refer Figures 1-6 as shown, it includes a motor main body 1, a waterproof component 2, a water sweeping mechanism, and a heat dissipation mechanism.

[0033] Among them, the motor main body 1 is used to convert electrical energy into mechanical energy, and a transmission rod 101 is provided on the motor main body 1.

[0034] Refer Figures 1-5As shown, the waterproof component 2 is installed outside the motor body 1 to protect the motor body 1 and reduce the probability of parts corrosion caused by rainwater. The waterproof component 2 includes a waterproof tank 201, with insertion holes drilled in the inner side wall of the waterproof tank 201. A top cover 202 is hinged to the waterproof tank 201 to seal it. A rubber ring 203 is installed on the top cover 202, which has a certain degree of flexibility to facilitate the insertion of the transmission rod 101 into the rubber ring 203. A sleeve 204 is inserted and connected to the rubber ring 203 to protect the transmission rod 101. A strip-shaped opening is drilled in the top cover 202, and a pair of... A sliding groove with a strip-shaped opening has a sliding block 205 installed inside. Each of the two side walls of the sliding block 205 is provided with a sliding element, which is slidably connected to the sliding groove. An insert 206 is connected to the side wall of the sliding block 205. The insert 206 passes through the side wall of the top cover 202, allowing the insert 206 to move with the sliding block 205. The insert 206 is also correspondingly set with the insertion hole, so that the top cover 202 can be fixed to the side wall of the waterproof bucket 201, further improving the protective effect. The waterproof bucket 201 is filled with a winding stator 208 to generate a rotating magnetic field. The winding stator 208 is a technology known to those skilled in the art and will not be described in detail here.

[0035] Preferably, a nylon buckle is installed on the inner side wall of the sleeve 204, and a drying cotton is installed on the nylon buckle, so that the drying cotton can be replaced and is easy to use. The drying cotton absorbs the moisture in the sleeve 204, which improves the protective effect of the sleeve 204 on the transmission rod 101. The raw material of the drying cotton is a blend of polyester fiber and viscose fiber, which has excellent water absorption and can keep the transmission rod 101 drier.

[0036] In addition, a handle 207 is provided on the top cover 202. The handle 207 is welded to the top cover 202, which improves the installation firmness of the handle 207. The handle 207 is provided with anti-slip texture, which effectively improves the friction and makes it easier for users to open or close the top cover 202, thus improving the ease of use.

[0037] The waterproof bucket 201 has a lifting ring on its side wall. The outer surface of the lifting ring has anti-slip texture, which effectively improves the friction and makes it easy for users to lift the waterproof bucket 201 for movement, thus improving ease of use. The lifting ring is made of thermosetting plastic, which has excellent bending resistance and enhances durability.

[0038] In addition, a water-sweeping mechanism is installed at the bottom of the waterproof bucket 201 for cleaning up accumulated water.

[0039] Specifically, the water sweeping mechanism includes a mounting block 3. Inside the mounting block 3, there is a motor 301. The bottom of the motor 301 is electrically connected to an output shaft 302. At the bottom of the mounting block 3, there is a rotating block 303. The rotating block 303 is connected to the output shaft 302, enabling the output shaft 302 to drive the rotating block 303 to rotate. An installation ring 304 is installed on the outer surface of the rotating block 303. At the bottom of the rotating block 303, there is a base 306, which is used to improve the grounding stability of the device. There is a first rotating shaft between the mounting block 3 and the rotating block 303, and a second rotating shaft between the rotating block 303 and the base 306, enabling the rotating block 303 to rotate smoothly between the mounting block 3 and the base 306.

[0040] Among them, the material of the installation ring 304 is hard rubber, which has high strength and certain ductility at the same time, facilitating the installation of the installation ring 304 onto the rotating block 303. And a plurality of water sweeping members 305 are evenly distributed on the outer surface of the installation ring 304. When the rotating block 303 starts to rotate, the water sweeping members 305 will rotate accordingly, effectively cleaning the accumulated water around the base 306, reducing the accumulation amount of rainwater, and improving the protection performance. Since the plurality of water sweeping members 305 occupy a large space, the installation ring 304 can be removed to facilitate the storage of the waterproof bucket 201.

[0041] Specifically, the heat dissipation mechanism is provided on the side wall of the waterproof bucket 201, and is used to help the motor main body 1 perform heat dissipation and cooling work.

[0042] Refer Figure 5 As shown, the heat dissipation mechanism includes a water collection tank 4. The water collection tank 4 is provided on one side wall of the waterproof bucket 201. On one side wall of the water collection tank 4, there are a pair of connecting pipes 402. The connecting pipes 402 penetrate through the waterproof bucket 201, and the other end of the connecting pipe 402 is connected to a heat dissipation member 403. Since the waterproof bucket 201 has strong sealing performance, the heat dissipation member 403 is used to help the motor main body 1 perform heat dissipation work. The connecting pipe 402 guides the rainwater in the water collection tank 4 into the heat dissipation member 403. The heat dissipation member 403 is in contact with the motor main body 1, and absorbs the heat outside the motor main body 1 through the rainwater. When the local heat of the motor main body 1 rises, the rainwater will be locally heated accordingly. When the temperature of the rainwater rises, its density decreases, and the rainwater with low density will float upward. After movement, the heat of the rainwater will gradually become uniform, and effective heat absorption work can be carried out.

[0043] Among them, a funnel member 401 is provided on the water collection tank 4, which expands the area of the water collection tank 4 for receiving rainwater and can receive more rainwater. A filter screen is installed at the bottom of the funnel member 401, which is used to filter out particulate matters such as sand and gravel, reducing the probability of particulate matters wearing the inside of the heat dissipation member 403. The mesh number of the filter screen is 500 meshes, which can effectively improve the filtering efficiency.

[0044] Specifically, the heat sink 403 is cylindrical, which allows it to fit better against the motor body 1 for heat dissipation. The heat sink 403 is made of copper, which has excellent heat transfer performance. A drain pipe 404 is provided on the side wall of the heat sink 403. The drain pipe 404 passes through the waterproof tank 201 and is used to drain rainwater from the heat sink 403 after use. A first-line leak-proof cap is threaded to the opening of the drain pipe 404.

[0045] In addition, a water outlet pipe 405 is provided on one side wall of the water collection tank 4. A second leak-proof cap is threaded to the opening of the water outlet pipe 405. When the rainfall is heavy, the leak-proof cap can be removed, and the water outlet pipe 405 can drain the excess rainwater in the water collection tank 4 to reduce the occurrence of the water collection tank 4 being too full. Preferably, the diameter of the water outlet pipe 405 is 50mm.

[0046] In practical use, place the motor body 1 inside the waterproof bucket 201, then remove the sleeve 204 from the rubber ring 203, slide the sliding block 205 to the end of the strip opening near the rubber ring 203, and then flip the top cover 202 towards the motor body 1 so that the transmission rod 101 passes through the rubber ring 203. Depending on whether the motor body 1 is used, the sleeve 204 can be optionally inserted and connected to the rubber ring 203. When the transmission rod 101 passes through the rubber ring 203, the insertion hole and the top cover 202 are approximately parallel. Push the sliding block 205 to the end of the strip opening away from the rubber ring 203 so that the insert 206 is inserted and connected to the insertion hole, thereby fixing the top cover 202 to the side wall of the waterproof bucket 201, thus sealing the motor body 1 inside the waterproof component 2. When the water accumulation is large, the motor 30 When activated, the water-sweeping component 305 begins to rotate, effectively sweeping away the water accumulated around the base 306, reducing the amount of rainwater accumulation, and thus reducing the contact between the device and rainwater. The water collection tank 4 continuously collects rainwater during rainfall. The rainwater enters the heat sink 403 through the connecting pipe 402. The rainwater in the heat sink 403 begins to absorb the heat emitted by the motor body 1 during operation. When the rainwater in the water collection tank 4 begins to rise rapidly, the second leak-proof cover on the outlet pipe 405 can be removed to drain the rainwater from the water collection tank 4. After the rainwater used for heat absorption in the heat sink 403 has been used for a certain period of time, the first leak-proof cover on the drain pipe 404 can be removed to drain the rainwater from the heat sink 403. Then, the drain pipe 404 is sealed, and rainwater accumulates again in the heat sink 403, continuing to dissipate heat for the motor body 1.

[0047] As can be seen from the above technical solutions, the present invention has the following beneficial effects:

[0048] This invention provides a waterproof device for three-phase asynchronous motors used in steel mill roller conveyors, making the motor less susceptible to component corrosion in environments with large amounts of water accumulation, thereby improving its service life.
