Description

Technical Field

[0001] The invention relates to the technical field of explosion-proof motors, and in particular to a cooling type explosion-proof motor. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magnetic-electrical rotation torque. Electric motors are divided into DC motors and AC motors according to the power source used. Most of the electric motors we commonly use are AC motors.

[0003] Explosion-proof motors are a type of electric motor that can be used in flammable and explosive places and do not generate sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, they are also widely used in textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, medicine and other departments. Explosion-proof motors are the main power equipment and are usually used to drive pumps, fans, compressors and other transmission machinery.

[0004] The utility model patent with Chinese patent announcement number: CN207573150U discloses a cooling-type explosion-proof motor, including a casing, a junction box is fixedly connected to the upper part of the side surface of the casing, a box cover is provided on the upper surface of the junction box, a plurality of heat dissipation fins are provided on the side surface of the casing, and a graphene patch is provided on the upper surface of each heat dissipation fin, a hollow copper tube is provided on the upper part of the side surface of the casing, the hollow copper tube is distributed in an S shape on the side surface of the casing, the hollow copper tube is in contact with the side surface of the heat dissipation fin, and the hollow copper tube and the heat dissipation fin are arranged correspondingly up and down, a rear cover is provided on the front surface of the casing, a strip air outlet slot is provided on the front surface of the rear cover, a support plate is provided on the lower surface of the casing, and two fixed plates are provided on the upper surface of the support plate, and the two fixed plates are fixedly connected to the casing.

[0005] In the above patent, although the motor can be cooled by the operation of fans and water pumps, the use of fans and water pumps is not only too costly, but also takes up too much space during installation, which easily leads to the overall structure being too large and insufficient in practicality.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a cooling type explosion-proof motor, which has the following beneficial effects:

[0022] 1. The cooling explosion-proof motor controls the driving motor to rotate the shaft. The shaft rotates through the first thread and the second thread in opposite directions provided on the outer wall thereof to drive the first nut and the second nut to move in opposite directions. When the first nut and the second nut are close to each other, the first connecting plate and the second connecting plate can make the first jacket and the second jacket close to each other. When the first jacket and the second jacket are close to each other, the positioning plate can clamp the motor body and fix the position of the motor body, so as to facilitate cooling of the motor body and make installation more convenient and quick.

[0023] 2. For the cooling explosion-proof motor, when the first connecting plate and the second connecting plate are close to each other, the water bag will be squeezed by the push rod and the clamping plate, so that the water in the water bag cooled by the refrigeration plate assembly flows to the heat dissipation pipe through the water outlet pipe, the hose and the dispersion pipe, thereby reducing the temperature around the motor body, thereby achieving the purpose of cooling the motor body. It is no longer necessary to use electric machinery such as water pumps, which has a lower cost and an excellent cooling effect.

[0024] 3. The cooling explosion-proof motor, the first jacket and the second jacket are both composed of a jacket body and a base plate, and a vertical rod, a pressure plate and a first spring are arranged between the jacket body and the base plate. When the motor body is running, the first spring can buffer the up and down vibration of the motor body, and the shock absorbing effect is better, which can effectively reduce the vibration of the motor body.

[0025] 4. For the cooling explosion-proof motor, when the first jacket and the second jacket approach each other and clamp the motor body through the positioning plate, the positioning plate will gradually approach the first jacket and the second jacket and compress the second spring. At this time, the elastic force of the second spring can buffer the left and right vibrations of the motor body during operation, further ensuring the shock absorption effect of the overall device.

[0026] 5. The cooling explosion-proof motor has several spirally opened silencer holes inside the positioning plate, and the silencer holes and the serpentine channel are interconnected. The noise generated when the motor body is running can be discharged through the silencer holes and the serpentine channel. On the way of discharge, the noise is first reflected by the spirally opened silencer holes and offset each other, and then absorbed by the silencer cotton on the inner wall of the serpentine channel, finally achieving an excellent silencer effect and eliminating the noise generated when the motor body is running.

The first connecting plate 9 and the second connecting plate 10 are close to each other, which will squeeze the water bag 15 through the push rod 11 and the clamping plate 12, so that the water cooled by the refrigeration plate assembly 14 in the water bag 15 flows to the heat dissipation pipe 30 through the water outlet pipe 16, the hose 17 and the dispersion pipe 29, thereby reducing the temperature around the motor body 22, thereby achieving the purpose of cooling the motor body 22, and no longer need to use electric machinery such as a water pump, the cost is lower, and the cooling effect is also very good.

[0043] In this embodiment, the first jacket 18 and the second jacket 19 both include a jacket body 23 and a bottom plate 24, a vertical rod 25 is evenly fixedly installed on the top of the bottom plate 24, a pressure plate 26 is fixedly connected to the top of the vertical rod 25, and a first spring 27 is fixedly connected to the top of the pressure plate 26, and a mounting groove 28 is opened inside the jacket body 23, and the pressure plate 26 and the first spring 27 are arranged inside the mounting groove 28. When the motor body 22 is running, the first spring 27 can buffer the up and down vibration of the motor body 22, and the shock absorbing effect is better, which can effectively reduce the shaking of the motor body 22, and the mounting groove 28 also forms a limiting hole where the vertical rod 25 passes, and a buffer rubber is fixedly installed on the inner wall of the limiting hole. On the one hand, it is to protect the vertical rod 25, and on the other hand, it also has a certain left and right shock absorbing effect.

[0044] In this embodiment, an insertion rod 20 is inserted into the lower part of the first jacket 18 and the second jacket 19, an arc-shaped bracket 21 is provided in the middle of the insertion rod 20, and a motor body 22 is provided on the top of the arc-shaped bracket 21. Even if the first jacket 18 and the second jacket 19 are separated from each other, the motor body 22 can still be placed on the arc-shaped bracket 21 and will not fall off.

[0045] In this embodiment, a slot 31 is further provided inside the first jacket 18 and the second jacket 19, and a movable rod 32 is inserted into the slot 31. A positioning plate 34 is fixedly installed on the inward end of the movable rod 32. The inward side of the positioning plate 34 is an arc surface, and a second spring 33 is fixedly installed between the outer wall of the positioning plate 34 and the inner wall of the first jacket 18 and the second jacket 19.

[0046] In this embodiment, a plurality of silencer holes 35 are evenly opened inside the positioning plate 34, and the plurality of silencer holes 35 are opened in a spiral shape inside the positioning plate 34. A serpentine channel 36 is opened inside the movable rod 32, and silencer cotton is arranged on the inner wall of the serpentine channel 36.

The output end of the temperature sensor is electrically connected to the circuit board. The output end of the circuit board is electrically connected to the input end of the drive motor 3. When the temperature sensor senses that the temperature of the motor body 22 is not high and does not need to be cooled, the drive motor 3 is controlled to operate through the circuit board to separate the first jacket 18 and the second jacket 19 from each other. Although the first jacket 18 and the second jacket 19 are separated from each other, the positioning plate 34 will still be pressed against the motor body 22 under the elastic force of the second spring 33 to fix the position of the motor body 22. At the same time, the push rod 11 and the clamping plate 12 have cancelled the squeezing of the water bag 15, and the water in the heat dissipation pipe 30 will flow back to the water bag 15, and rely on the refrigeration plate assembly 14 to cool the water in the water bag 15 so that it can flow into the heat dissipation pipe 30 to dissipate heat for the motor body 22 next time.

[0048] The working principle and use process of the present invention:

[0049] Controlling the driving motor 3 to run can rotate the rotating shaft 4 fixedly connected to the top of its output shaft, and the rotating shaft 4 can drive the first nut 7 and the second nut 8 to move in opposite directions through the first thread 5 and the second thread 6 in opposite directions provided on the outer wall thereof, and the first nut 7 and the second nut 8 to move in opposite directions can directly drive the first jacket 18 and the second jacket 19 to move in opposite directions through the first connecting plate 9 and the second connecting plate 10;

[0050] When the motor body 22 needs to be installed, the driving motor 3 is first controlled to operate so that the first jacket 18 and the second jacket 19 are separated from each other. At this time, the motor body 22 can be placed on the arc bracket 21. After being placed, the driving motor 3 is controlled to operate again so that the first jacket 18 and the second jacket 19 are close to each other. The first jacket 18 and the second jacket 19 are close to each other and can clamp the motor body 22 through the positioning plate 34 (the second spring 33 is compressed at this time), fix the position of the motor body 22, facilitate cooling of the motor body 22, and make installation more convenient and quick.

[0051] When the first jacket 18 and the second jacket 19 are close to each other, the first connecting plate 9 and the second connecting plate 10 are also close to each other. The first connecting plate 9 and the second connecting plate 10 are close to each other, which will squeeze the water bag 15 through the push rod 11 and the clamping plate 12, so that the water in the water bag 15 cooled by the refrigeration plate assembly 14 flows to the heat dissipation pipe 30 through the water outlet pipe 16, the hose 17 and the dispersion pipe 29, thereby reducing the temperature around the motor body 22, thereby achieving the purpose of cooling the motor body 22, and no longer needing to use electric machinery such as a water pump, the cost is lower, and the cooling effect is also very good;

[0052] When the temperature sensor senses that the temperature of the motor body 22 is not high and does not need to be cooled, the circuit board controls the driving motor 3 to operate, so that the first jacket 18 and the second jacket 19 are separated from each other. Although the first jacket 18 and the second jacket 19 are separated from each other, the positioning plate 34 will still be pressed against the motor body 22 under the elastic force of the second spring 33 to fix the position of the motor body 22. At the same time, the push rod 11 and the clamping plate 12 have cancelled the squeezing of the water bag 15, and the water in the heat dissipation pipe 30 will flow back to the water bag 15, and the water in the water bag 15 will be cooled by the cooling plate assembly 14, so that it can flow into the heat dissipation pipe 30 to dissipate heat for the motor body 22 next time.

[0053] The first jacket 18 and the second jacket 19 are both composed of a jacket body 23 and a bottom plate 24, and a vertical rod 25, a pressure plate 26 and a first spring 27 are further provided between the jacket body 23 and the bottom plate 24. Specifically, the vertical rod 25 is installed on the bottom plate 24, the pressure plate 26 is installed on the vertical rod 25, and the first spring 27 is also installed on the vertical rod 25 and is located inside the jacket body 23. When the motor body 22 is running, the first spring 27 can buffer the up and down vibration of the motor body 22, and the shock absorbing effect is better, which can effectively reduce the vibration of the motor body 22;

[0054] As described above, when the first jacket 18 and the second jacket 19 approach each other and clamp the motor body 22 through the positioning plate 34, the positioning plate 34 gradually approaches the first jacket 18 and the second jacket 19 and compresses the second spring 33. At this time, the elastic force of the second spring 33 can buffer the left and right vibrations of the motor body 22 during operation, further ensuring the shock absorption effect of the overall device;

[0055] It is worth mentioning that a plurality of spirally opened silencer holes 35 are provided inside the positioning plate 34, and the silencer holes 35 and the serpentine channel 36 are interconnected. The noise generated when the motor body 22 is running can be discharged through the silencer holes 35 and the serpentine channel 36. On the way of discharge, the noise is first reflected by the spirally opened silencer holes 35 and offset each other, and then absorbed by the silencer cotton on the inner wall of the serpentine channel 36, finally achieving an excellent silencer effect and eliminating the noise generated when the motor body 22 is running.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
