Description

Technical Field

[0001] The utility model relates to the technical field of coal mine safety, in particular to a safety isolation device for coal mine electromechanical equipment. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. In coal mine production operations, the safe and stable operation of electromechanical equipment is crucial to ensuring the continuity and stability of the entire production system. However, due to the particularity of the coal mine working environment, such as the presence of a large amount of dust, moisture, vibration and other factors, electromechanical equipment is easily damaged or fails during operation. In addition, once the equipment fails, if it is not isolated in time, it may also trigger a chain reaction, causing the entire production system to be paralyzed. These electromechanical equipment are usually installed in isolation boxes;

[0003] The isolation box can better protect electromechanical equipment and has better airtightness. However, when electromechanical equipment is working, heat is often generated. If the temperature inside the isolation box is too high, it will affect the normal operation of the electromechanical equipment. While dissipating heat, a large amount of dust will be sucked in, which can easily clog the filter. Failure to clean it manually in time may cause the electromechanical equipment to malfunction.

[0024] See also Figures 1 to 7 In an embodiment of the utility model, a safety isolation device for electromechanical equipment in a coal mine comprises an isolation box 100, wherein the isolation box 100 comprises a box body 110, wherein a plurality of shock absorbers 140 are fixedly connected to the bottom surface of the box body 110, and a fixing plate 150 is fixedly connected to the top surface of the plurality of shock absorbers 140, and a box door 120 is provided on the front side wall of the box body 110, wherein two hinges 122 are rotatably connected between the box door 120 and the box body 110, and an arc-shaped handle 121 is fixedly connected to the outer wall of the box door 120, and a transparent plate 130 is provided on the rear side wall of the box door 120 and the box body 110, and four support units 160 are fixedly connected to the bottom surface of the box body 110 at equal distances, and two dovetail grooves 111 are provided on the left and right side walls of the box body 110, and a heat dissipation mechanism 200 is slidably inserted in the dovetail groove 111.

[0025] Specifically, the electromechanical equipment is fixed to the fixing plate 150 with bolts. During mining operations, vibrations are inevitable. By fixing the shock absorber 140 on the bottom surface of the fixing plate 150, the shock absorber 140 can absorb these vibrations, disperse and reduce the impact force on the electromechanical equipment.

[0026] Embodiment 1

[0027] like Figure 3-5As shown, in this embodiment, the heat dissipation mechanism 200 includes a left side plate 210 and a right side plate 220, the center position of the left side plate 210 is fixedly connected to a heat dissipation box 211, the side wall of the left side plate 210 close to the box body 110 is provided with two plug-in blocks 216, the two plug-in blocks 216 and the two dovetail grooves 111 located on the left side of the box body 110 are slidably plugged, the interior of the heat dissipation box 211 is fixedly connected to a connecting frame 213, the interior of the connecting frame 213 is fixedly connected to a motor 214, the motor shaft of the motor 214 is drivingly connected to a fan blade 215, the side wall of the heat dissipation box 211 away from the box body 110 is fixedly connected to a filter screen 212, the outer wall of the filter screen 212 is sleeved and fixed with a cleaning mechanism 300, and the right side Two plug-in blocks 221 are provided on the side wall of the plate 220 close to the box body 110, and the two plug-in blocks 221 are slidably plugged into the two dovetail grooves 111 located on the right side of the box body 110. A square frame 222 is fixedly connected to the center position of the right side plate 220, and a strip groove 223 is provided on the top surface of the square frame 222. A filter screen 225 is slidably plugged into the inside of the strip groove 223, and the top surface of the filter screen 225 is fixedly connected to a limiting plate 224, and the bottom surface of the limiting plate 224 is in contact with the top surface of the square frame 222. The top surfaces and side walls of the right side plate 220 and the left side plate 210 are screwed together with a number of bolts, and dustproof strips are bonded and fixed to the gaps after the box body 110 and the left side plate 210 and the right side plate 220 are plugged together.

[0028] In this embodiment, after the electromechanical equipment is installed on the fixing plate 150, the plug-in block 1 216 and the plug-in block 221 are respectively plugged into the dovetail groove 111, and the left side plate 210, the right side plate 220 and the box body 110 are fixed together by fastening bolts. This connection is convenient for disassembly and assembly, and is convenient for subsequent maintenance operations. Dust-proof strips are bonded and fixed at the gaps between the three to ensure sealing and prevent external dust from entering the box body 110 through the gaps. When the electromechanical equipment in the box body 110 is running, heat is generated, which will cause the temperature inside the box body 110 to rise. When the internal temperature rises to a preset value, the motor shaft of the drive motor 1 214 is transmitted to the fan blade 215, so that the fan blade 2 15 rotates at a high speed, and the external cold air is sucked into the box body 110 after being filtered by the filter screen 1 212, and then filtered and blown out through the filter screen 2 225, so as to cool the interior of the box body 110 to prevent the temperature in the box body 110 from being too high and affecting the normal operation of the electromechanical equipment. The filter screen 1 212 and the filter screen 225 block the external dust and prevent the influence of excessive dust on the electromechanical equipment. The position of the filter screen 225 is the air outlet, and the filter screen 225 and the square frame 222 are slidably connected. When the dust on the filter screen 225 is accumulated enough, the limit plate 224 can be held to pull the filter screen 225 out of the square frame 222 for cleaning or replacement.

The four support units 160 can be adjusted separately to improve the stability of the entire device. The adjustment process is relatively simple, and the operator can quickly complete the adjustment work.

[0031] Embodiment 2

[0032] On the basis of Example 1, in order to compensate for the fact that when the fan blades 215 are driven to rotate for heat dissipation in Example 1, external dust will be adsorbed on the filter 212, a large amount of dust will easily adhere to the surface of the filter 212 over a long period of time. If it is not cleaned in time, the filter holes of the filter 212 will be clogged, affecting the heat dissipation efficiency.

[0033] like Figure 6 As shown, in this embodiment, the cleaning mechanism 300 includes a dust removal frame 310, the inner wall of the dust removal frame 310 and the outer wall of the heat dissipation box 211 are sleeved and fixed, the interior of the dust removal frame 310 is located on the left and right sides and is fixedly connected to racks 320, the interior of the dust removal frame 310 is symmetrically fixed with two motors 2, the motor shafts of the two motors 2 are both transmission-connected with rotating rods 340, the outer walls of the two rotating rods 340 are sleeved and fixed with gears 330, and the two gears 330 are respectively connected to the two racks 320 meshing transmission, the outer walls of the two rotating rods 340 are rotatably connected with square rods 351, and a cleaning brush 350 is fixedly connected between the two square rods 351. The bristles of the cleaning brush 350 are in contact with the surface of the filter 212. A sliding groove is provided on the inner wall of the dust removal frame 310, and the end of the rotating rod 340 is slidably connected to the inside of the sliding groove. An empty groove is provided at the bottom of the dust removal frame 310, and a dust box 360 is slidably inserted in the empty groove, and a handle is fixedly connected to the end side of the dust box 360.

[0034] During the specific implementation, the cleaning cycle is set in advance, and the motor shafts of the two motors 2 are driven to transmit to the two gears 330 in reverse direction, so that the two gears 330 rotate and mesh with the two racks 320 respectively, so that the rotating rod 340 slides in the slide groove of the dust removal frame 310. By controlling the forward or reverse rotation of the motor shaft of the motor 2, the cleaning brush 350 can be driven to move up and down. The bristles of the cleaning brush 350 will brush the surface of the filter 1 212, so that the dust adhered to its surface falls into the dust box 360, so as to avoid excessive dust clogging the filter 1 212. The swept dust is stored in the dust box 360. The dust box 360 can be pulled out after a period of time, and the dust inside can be cleaned.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
