[0017] The beneficial effects of the present invention:

[0018] 1. The present invention can support and fix the bottom of the motor by setting up a base mechanism. When the motor is working, several dust-proof cover mechanisms are in a closed state, and the sealing mechanism fixes the several closed dust-proof cover mechanisms to prevent dust from contaminating the motor. The temperature sensor detects the working temperature of the motor and transmits the detection signal to the controller. When the detected temperature is greater than the preset temperature, the heat dissipation structures on the base mechanism and the dust-proof cover mechanism are started for active heat dissipation. When the motor needs to be repaired, the sealing mechanism is removed, and the several dust-proof cover mechanisms are unfolded outward, facilitating the user to disassemble and maintain the motor on the top of the base mechanism.

When the dust-proof cover mechanism is closed, several cover bodies, bending parts and fixing strips fit together to form a circular cover to protect the motor. During the protection process, the heat conduction sheet conducts passive heat dissipation to reduce the temperature of the air in the inner cavity of the dust-proof cover mechanism. When the cover body needs to be unfolded, the cover body is rotated outward, and the cover body drives the rotating rod to rotate on the inner wall of the rotating seat. The fixing piece fixes and supports the rotating seat. After unfolding outward, the motor is exposed to the outside. When the cover body is reset, the rubber sealing strip fits on the top of the fixing piece to seal the connection between the cover body and the fixing piece. When active heat dissipation is required, the chimney exhaust component extracts the hot air in the inner cavity of the dust-proof cover mechanism, and the cold air is discharged from the bottom of the motor, then contacts the surface of the motor, takes away the heat on the surface of the motor, and finally enters the top of the inner cavity of the dust-proof cover mechanism and is quickly discharged through the chimney exhaust component. During the active heat dissipation process, different heat dissipation efficiency levels are set according to the working temperature of the motor, and different numbers of chimney exhaust components are started for different heat dissipation efficiency levels.

Detailed implementation manners

[0031] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0032] As Figures 1 - 10 shown, this embodiment provides a motor bottom fixing seat, including a base mechanism 100, a dust-proof cover mechanism 200 is circumferentially installed on the surface of the base mechanism 100, and a plugging mechanism 300 is installed on the top of the dust-proof cover mechanism 200.

[0033] Furthermore, the motor 400 is fixedly installed on the top of the base mechanism 100 and is located inside the dust-proof cover mechanism 200.

[0034] Furthermore, the number of the dust-proof cover mechanisms 200 is several, and several dust-proof cover mechanisms 200 are movably connected to each other. Several dust-proof cover mechanisms 200 form a circular cover for protecting the motor 400. A through hole is opened on the dust-proof cover mechanism 200 at the output shaft of the motor 400, and a disposable filter screen is pasted inside the through hole to seal the through hole for dust prevention. The output shaft of the motor 400 passes through the disposable filter screen and is equipped with a coupling.

[0035] The motor 400 is equipped with a temperature sensor and a controller.

[0036] The motor 400 is installed on the base mechanism 100, and the base mechanism 100 supports and fixes the bottom of the motor 400. When the motor 400 is working, several dust cover mechanisms 200 are in a closed state, and the blocking mechanism 300 fixes the closed dust cover mechanisms 200 to prevent dust from contaminating the motor 400. The temperature sensor detects the working temperature of the motor 400 and transmits the detection signal to the controller. When the detected temperature is greater than the preset temperature, the heat dissipation structure on the base mechanism 100 and the dust cover mechanism 200 is started to perform active heat dissipation. When the motor 400 needs to be inspected and repaired, the blocking mechanism 300 is removed and the several dust cover mechanisms 200 are unfolded outward to facilitate the user to disassemble and maintain the motor 400 on the top of the base mechanism 100.

[0037] Furthermore, the base mechanism 100 includes a base body 101 , the four corners of the top of the base body 101 are fixedly connected with rubber shock-absorbing seats 104 , an air intake fan 105 is fixedly installed at the center of the bottom of the base body 101 , and an air intake hole 106 used in conjunction with the air intake fan 105 is opened on the base body 101 .

[0038] Furthermore, legs 103 are fixedly connected to the four corners of the bottom of the seat body 101 , and a fixing groove 102 is opened on the surface of the seat body 101 .

[0039] Furthermore, a mounting flange is provided at the bottom of the supporting leg 103, and a flange hole is provided on the mounting flange.

[0040] By setting up the base mechanism 100, the bottom of the motor 400 can be supported and fixed. The motor 400 is fixed to the rubber shock-absorbing seat 104 by bolts. The rubber shock-absorbing seat 104 is installed at the bottom of the motor 400 to absorb the vibration of the motor 400 during operation. The seat body 101 supports the rubber shock-absorbing seat 104 and the motor 400. During the operation of the base mechanism 100, the air inlet fan 105 draws cold air from the bottom of the seat body 101 through the first stainless steel filter 107. The first stainless steel filter 107 filters dust. The filtered cold air passes through the air inlet hole 106 and enters the inner cavity of the dust cover mechanism 200 to take away the heat from the surface of the motor 400. The support leg 103 supports the bottom of the seat body 101, and the bottom of the support leg 103 is fixed to the support platform through the mounting flange.

[0041] Furthermore, the dust cover mechanism 200 includes a cover body 201 and a fixing plate 207 , the fixing plate 207 is fixedly connected to the fixing groove 102 , the top of the cover body 201 is connected to a bending portion 202 , and the top of the bending portion 202 is connected to a fixing strip 204 .

[0042] Further, the bent portion 202 is bent inward, the diameter of the cover body 201 is larger than that of the bent portion 202, and the diameter of the bent portion 202 is larger than that of the fixing strip 204.

[0043] By gradually decreasing the diameter, the space volume inside the cover body 201 can be made large to accommodate the motor 400, so that the chimney exhaust components 203 on the bent portion 202 can be closer to each other for centralized exhaust. The area of the cold air is large at the bottom of the inner cavity of the dust-proof cover mechanism 200 and small at the top of the inner cavity of the dust-proof cover mechanism 200, forming a siphon effect. And it is convenient for the sealing mechanism 300 to fix several fixing strips 204 and seal the openings at the tops of the fixing strips 204, reducing the disassembly difficulty.

[0044] Further, a rotating seat 208 is fixedly connected to the surface of the fixing piece 207, a rotating rod 209 is rotatably connected inside the rotating seat 208, and the top of the rotating rod 209 is fixedly connected to the surface of the cover body 201.

[0045] Further, a chimney exhaust component 203 is fixedly connected to the fixing strip 204, and the bottom of the chimney exhaust component 203 extends to the bottom of the fixing strip 204.

[0046] Further, a rubber sealing strip 206 is fixedly connected to the bottom of the cover body 201, and the bottom of the rubber sealing strip 206 is movably connected to the top of the fixing piece 207.

[0047] Further, a plurality of heat conducting sheets 205 are installed on the cover body 201, one side of the heat conducting sheet 205 extends to the inside of the cover body 201, and the other side of the heat conducting sheet 205 extends to the outside of the cover body 201.

[0048] By setting up the dust-proof cover mechanism 200, the motor 400 can be protected. When the dust-proof cover mechanism 200 is closed, several cover bodies 201, bending parts 202 and fixing strips 204 are attached together to form a circular cover to protect the motor 400. During the protection process, the heat-conducting sheet 205 conducts passive heat dissipation to reduce the temperature of the air inside the dust-proof cover mechanism 200. When it is necessary to unfold the cover body 201, the cover body 201 is rotated outward. The cover body 201 drives the rotating rod 209 to rotate on the inner wall of the rotating seat 208. The fixing piece 207 fixedly supports the rotating seat 208. After unfolding outward, the motor 400 is exposed to the outside. When resetting the cover body 201, the rubber sealing strip 206 is attached to the top of the fixing piece 207 to seal the connection between the cover body 201 and the fixing piece 207. When active heat dissipation is required, the chimney exhaust component 203 extracts the hot air inside the dust-proof cover mechanism 200. The cold air is discharged from the bottom of the motor 400, then contacts the surface of the motor 400, takes away the heat on the surface of the motor 400, and finally enters the top of the inner cavity of the dust-proof cover mechanism 200 and is quickly discharged through the chimney exhaust component 203. During the active heat dissipation process, different heat dissipation efficiency levels are set according to the working temperature of the motor 400, and different numbers of chimney exhaust components 203 are started for different heat dissipation efficiency levels.

[0049] Further, the chimney exhaust component 203 includes an air outlet chimney 210. The air outlet chimney 210 is fixedly installed inside the bending part 202. The bottom of the air outlet chimney 210 extends to the bottom of the bending part 202, and the top of the air outlet chimney 210 extends to the top of the bending part 202. An installation sleeve 211 is installed inside the air outlet chimney 210, and an air outlet fan 212 is installed inside the installation sleeve 211. The top of the air outlet chimney 210 is fixedly connected with a threaded ring 215. A nut 214 is threadedly sleeved on the surface of the threaded ring 215. The inner wall of the nut 214 is fixedly connected with a second stainless steel filter screen 213. The second stainless steel filter screen 213 is located at the air outlet end of the air outlet fan 212.

[0050] During the working process of the chimney exhaust component 203, the air outlet fan 212 extracts the hot air inside the dust-proof cover mechanism 200. The hot air enters through the bottom of the air outlet chimney 210 and is discharged to the outside through the top of the air outlet chimney 210 and the second stainless steel filter screen 213. The second stainless steel filter screen 213 is arranged outside the air outlet fan 212 to prevent dust from entering the inner cavity of the dust-proof cover mechanism 200 through the air outlet chimney 210. When it is necessary to clean the second stainless steel filter screen 213, the nut 214 is screwed out from the surface of the threaded ring 215 to disassemble and clean the second stainless steel filter screen 213. The installation sleeve 211 is threadedly connected with the inner wall of the air outlet chimney 210. When it is necessary to repair the air outlet fan 212, the installation sleeve 211 is screwed out from the inner wall of the air outlet chimney 210 to disassemble and repair the air outlet fan 212.

[0051] Further, the heat conducting sheet 205 includes a sheet body 216. The sheet body 216 is fixedly installed inside the housing 201. One side of the sheet body 216 extends to the inner side of the housing 201, and the other side of the sheet body 216 extends to the outside of the housing 201. A heat conducting liquid cavity 217, a diversion cavity 218, a capillary cavity 219, and a heat dissipation cavity 220 are formed inside the sheet body 216. The heat conducting liquid cavity 217 is located on one side inside the sheet body 216. The diversion cavity 218 is located outside the heat conducting liquid cavity 217 and communicates with it. The capillary cavity 219 is located at the top of the diversion cavity 218 and communicates with it. The number of the diversion cavity 218 and the capillary cavity 219 is several. The heat dissipation cavity 220 is located on the other side inside the sheet body 216 and communicates with the diversion cavity 218.

[0052] Further, the heat conducting liquid cavity 217, the diversion cavity 218, the capillary cavity 219, and the heat dissipation cavity 220 are filled with heat conducting liquid.

[0053] During the operation of the fixing piece 207, the heat conducting liquid cavity 217 is located inside the housing 201. The heat conducting liquid inside the heat conducting liquid cavity 217 absorbs the heat of the air inside the inner cavity of the dust-proof cover mechanism 200, and transfers the heat to the heat conducting liquid inside the diversion cavity 218, the capillary cavity 219, and the heat dissipation cavity 220 in sequence. These heat conducting liquids transfer the heat into the sheet body 216. The sheet body 216 transfers the heat to the cold air outside through its part located outside, to assist in heat dissipation and temperature reduction. By the combined use of the diversion cavity 218, the capillary cavity 219, and the heat dissipation cavity 220, the contact area between the heat conducting liquid and the sheet body 216 can be increased to efficiently transfer the heat of the heat conducting liquid.

[0054] Further, the housing 201 includes a protective layer 221. A wear-resistant and corrosion-resistant layer 222 is sprayed on the surface of the protective layer 221. A low-frequency sound-absorbing layer 223 is fixedly connected to the inner side of the protective layer 221. A high-frequency sound-absorbing layer 224 is fixedly connected to the inner side of the low-frequency sound-absorbing layer 223. A sealing and sound-insulating layer 225 is fixedly connected to the inner side of the high-frequency sound-absorbing layer 224.

[0055] Further, the material of the wear-resistant and corrosion-resistant layer 222 is ceramic coating, the material of the low-frequency sound-absorbing layer 223 is polyurethane foam, the material of the high-frequency sound-absorbing layer 224 is melamine foam, and the material of the sealing and sound-insulating layer 225 is glass fiber-reinforced epoxy resin.

[0056] Further, both the sheet body 216 and the protective layer 221 are made of aluminum alloy material.

[0057] Further, the structures of the fixing strip 204 and the bending part 202 are the same as those of the housing 201.

[0058] By providing the sheet body 216 made of aluminum alloy material and the protective layer 221, heat can be absorbed and the absorbed heat can be dissipated into the external air. The wear-resistant and corrosion-proof layer 222 is provided on the surface of the protective layer 221 to prevent the surface of the protective layer 221 from being corroded and worn, thereby extending its service life. The low-frequency sound-absorbing layer 223 and the high-frequency sound-absorbing layer 224 absorb the low-frequency and high-frequency noises passing through the sealed sound-insulating layer 225. The sealed sound-insulating layer 225 protects the inner side of the high-frequency sound-absorbing layer 224 and prevents dust from entering the inner cavity of the dust-proof cover mechanism 200, avoiding contamination of the motor 400. The sealed sound-insulating layer 225 can also reflect sound waves to enhance the sound-insulating effect.

[0059] Furthermore, the plugging mechanism 300 includes a clamp 301 and a rubber plug 302. The clamp 301 is movably sleeved on the surfaces of a plurality of fixing bars 204. An installation bolt 303 is passed through the clamp 301, and an installation nut 304 is threadedly sleeved on the installation bolt 303.

[0060] Furthermore, the rubber plug 302 is movably installed inside a plurality of fixing bars 204, and the bottom of the rubber plug 302 is conical.

[0061] By providing the plugging mechanism 300, it is convenient to fix and disassemble the dust-proof cover mechanism 200. During the fixing process, the clamp 301 is sleeved on the surfaces of a plurality of fixing bars 204, and then the rubber plug 302 is inserted into the inside of the fixing bars 204 to close the top of the fixing bars 204. After the fixing is completed, the installation bolt 303 is passed through the clamp 301, and the installation nut 304 is screwed onto the surface of the installation bolt 303. Pressure is applied to the clamp 301 through the installation bolt 303 and the installation nut 304, so that the clamp 301 is fastened to the surface of the fixing bars 204. When disassembling, the installation bolt 303 and the installation nut 304 are unscrewed, and the clamp 301 and the rubber plug 302 are moved upward for disassembly to release the fixing of the fixing bars 204.
