Technical Field
[0001] This utility model relates to the field of isolation equipment technology, and in particular to a safety isolation device for protecting coal mine electromechanical equipment. Background Technology
[0002] In the current booming development of the coal mining industry, electromechanical equipment, as the core driving force of coal mine production, is directly related to the production efficiency, economic benefits, and personnel safety of coal mines through its safe and stable operation.
[0003] The heat dissipation methods of the safety enclosures for large motors used in some mining crushers and conveyor belts are relatively inefficient. In the high-temperature, high-dust environment of coal mines with limited ventilation, it is difficult to quickly remove the heat generated by the motors during operation. The motors are in a high-temperature state for a long time, which will lead to the deterioration of the performance of internal components and the accelerated aging of insulation materials. In order to solve the above problems, this utility model provides a safety isolation device for protecting coal mine electromechanical equipment. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety isolation device for protecting coal mine electromechanical equipment.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A safety isolation device for protecting coal mine electromechanical equipment includes a base and a mining motor. A protective box is fixedly connected to the middle of the upper surface of the base, and the mining motor is fixedly installed inside the protective box. A protective cover is fixedly installed on the upper end of the protective box. A water-cooling jacket is fitted over the surface of the mining motor. A circulation component is provided on the upper surface of the protective cover. A cooling box is fixedly connected to one side of the upper surface of the base, and a circulation box is fixedly connected to the other side of the upper surface of the base. An air-cooling component is fixedly installed at one end of the upper surface of the base. Several cooling pipes are fixedly connected to the back of the circulation box, and the other ends of the cooling pipes are fixedly connected to the cooling box. A fixing component is fixedly connected to the lower surface of the base.
[0007] As a further improvement of this utility model, the circulation component includes a first mounting groove formed at one end of the upper surface of the protective cover. A micro pump is fixedly installed inside the first mounting groove. An inlet pipe is fixedly connected to the inlet end of the micro pump. The other end of the inlet pipe is fixedly connected to the cooling box. An outlet pipe is fixedly connected to the outlet end of the micro pump. The other end of the outlet pipe is fixedly connected to the water cooling jacket.
[0008] As a further improvement of this utility model, a circulation pipe is fixedly connected to the back of the water cooling jacket, and the other end of the circulation pipe passes through the protective cover and is fixedly connected to the circulation box.
[0009] As a further improvement of this utility model, the air-cooling component includes a mounting base fixedly installed at one end of the upper surface of the base. A second mounting groove is provided on the back of the mounting base. Several cooling fans are fixedly installed inside the second mounting groove. First threaded holes are provided on both sides of the upper surface of the base. First mounting bolts that are compatible with the first threaded holes are threaded to both sides of the lower end of the base.
[0010] As a further improvement of this utility model, several heat dissipation slots are provided on the back of the protective box.
[0011] As a further improvement of this utility model, the upper ends of both sides of the protective box are fixedly connected to a lower mounting plate, and the lower ends of both sides of the protective cover are fixedly connected to an upper mounting plate.
[0012] As a further improvement of this utility model, the lower mounting plate has second threaded holes on both sides of its upper surface, and the upper mounting plate has second mounting bolts that are adapted to the second threaded holes on both sides of its upper surface.
[0013] As a further improvement of this utility model, a bearing is fixedly connected to the front of the protective cover, and a coupling is rotatably connected inside the bearing. The coupling is fixedly installed on the power end of the mining motor.
[0014] As a further improvement of this utility model, the fixing component includes support seats fixedly connected to both ends of the lower surface of the base. Each of the two support seats has a sliding groove at its lower end. Two movable blocks are movably connected inside each of the two sliding grooves. Two fixing plates are fixedly connected to the lower ends of the four movable blocks. Third threaded holes are opened on both sides of the upper surface of each of the two fixing plates. Third mounting bolts adapted to the third threaded holes are threadedly connected to both sides of the upper surface of each of the two fixing plates. A threaded screw is rotatably connected inside one of the sliding grooves. Adjusting bolt holes adapted to the threaded screws are opened inside the two movable blocks. The threads of the two adjusting bolt holes are opposite. A buffer pad is fixedly connected to the lower end of each of the two fixing plates. A knob is rotatably connected to one side of one of the support seats, and the knob is connected to the threaded screw.
[0015] As a further improvement of this utility model, a thermally conductive patch is fixedly installed on the inner wall of the water-cooling jacket, and the thermally conductive patch is made of graphene.
[0016] The beneficial effects of this utility model are:
[0017] By setting up a circulation component, the graphene thermally conductive patches on the inner wall of the water-cooling jacket can quickly transfer the heat generated by the motor to the coolant during use. Then, a micro-pump drives the coolant to circulate between the cooling tank, the water-cooling jacket, and the circulation tank, continuously removing heat. At the same time, the cooling fan not only provides air cooling for the motor through the heat dissipation slots, but also cools the cooling pipes, accelerating the cooling of the coolant. This multi-dimensional heat dissipation method effectively avoids problems such as performance degradation or efficiency reduction caused by motor overheating, ensuring the stable operation of the motor under the complex working conditions of coal mines, extending the service life of the equipment, and reducing production downtime and maintenance costs caused by equipment failure.
[0018] By installing a protective enclosure, the motor is effectively isolated from dust, moisture, and debris in the coal mine environment during use, preventing these harmful substances from entering the motor. The protective cover and the protective enclosure are tightly connected by a lower mounting plate, an upper mounting plate, and a second mounting bolt, forming a closed space. The detachable design of the protective enclosure and cover makes daily inspection, maintenance, and upkeep of the mining motor more convenient, saving time and labor costs. Furthermore, the coupling is connected to the protective cover via bearings, ensuring power transmission while reducing direct impact from external factors on the coupling and motor. This significantly reduces the risk of motor damage during coal mine operations, improving the safety and reliability of the equipment.
[0019] By setting a fixed component, during use, rotating the screw with a knob drives two movable blocks to move in opposite directions or away from each other along the screw. This allows the fixed plate to be precisely adjusted according to the width of the mounting frame, enabling the device to flexibly adapt to mounting frames of various sizes and widths in coal mines. This improves the versatility and practicality of the device. At the same time, the buffer pad can absorb and disperse the vibration and impact from the mounting frame, reducing the risk of damage to the equipment caused by vibration and impact.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figures 1-4 A safety isolation device for protecting coal mine electromechanical equipment includes a base 1 and a mining motor 2. A protective box 3 is fixedly connected to the middle of the upper surface of the base 1. The mining motor 2 is fixedly installed inside the protective box 3. A protective cover 4 is fixedly installed at the upper end of the protective box 3. A water-cooling jacket 5 is fitted onto the surface of the mining motor 2. A circulation component is provided on the upper surface of the protective cover 4. A cooling box 6 is fixedly connected to one side of the upper surface of the base 1. A circulation box 7 is fixedly connected to the other side of the upper surface of the base 1. An air-cooling component is fixedly installed at one end of the upper surface of the base 1. Several cooling pipes 8 are fixedly connected to the back of the circulation box 7. The other ends of the cooling pipes 8 are all fixedly connected to the cooling box 6. A fixing component is fixedly connected to the lower surface of the base 1. The cooling pipes 8 are all made of copper, which has excellent thermal conductivity.
[0027] In this invention, the circulation assembly includes a first mounting groove formed at one end of the upper surface of the protective cover 4. The first mounting groove provides a dedicated mounting space for the micro pump 9, ensuring that the micro pump 9 can be securely mounted on the protective cover 4 and preventing shaking or displacement during operation. The micro pump 9 is fixedly installed inside the first mounting groove. As the power source for coolant circulation, the micro pump 9 continuously provides power for the flow of coolant. An inlet pipe 10 is fixedly connected to the inlet end of the micro pump 9, and the other end of the inlet pipe 10 is fixedly connected to the cooling tank 6. The inlet pipe 10 connects the micro pump 9 and the cooling tank 6, allowing coolant to flow smoothly from the cooling tank 6. The coolant flows into the micro pump 9, and the outlet end of the micro pump 9 is fixedly connected to the outlet pipe 11. The other end of the outlet pipe 11 is fixedly connected to the water cooling jacket 5. The water cooling jacket 5 tightly wraps the mining motor 2. After the coolant enters the water cooling jacket 5, it can directly contact the surface of the motor and quickly remove the heat generated by the motor. The back of the water cooling jacket 5 is fixedly connected to the circulation pipe 12. The circulation pipe 12 provides a return channel for the coolant after absorbing heat, so that the coolant can flow out of the water cooling jacket 5 smoothly. The other end of the circulation pipe 12 passes through the protective cover 4 and is fixedly connected to the circulation box 7. The circulation box 7 can temporarily store the coolant and perform preliminary cooling, preparing for the recirculation of the coolant.
[0028] The air-cooled assembly includes a mounting base 13 fixedly installed on one end of the upper surface of the base 1. A second mounting groove is provided on the back of the mounting base 13. Several cooling fans 14 are fixedly installed inside the second mounting groove. The simultaneous operation of several cooling fans 14 can generate stronger airflow, accelerate air flow, and improve heat dissipation efficiency. First threaded holes are provided on both sides of the upper surface of the base 1. First mounting bolts 15 that are compatible with the first threaded holes are threaded to both sides of the lower end of the base 1. Several heat dissipation slots 16 are provided on the back of the protective box 3. The heat dissipation slots 16 increase the air circulation inside the protective box 3, so that the air generated by the cooling fans 14 can better enter the protective box 3 to dissipate heat from the mining motor 2.
[0029] The upper ends of both sides of the protective box 3 are fixedly connected to the lower mounting plates 17, and the lower ends of both sides of the protective cover 4 are fixedly connected to the upper mounting plates 18. The upper surfaces of the lower mounting plates 17 are provided with second threaded holes on both sides, and the upper surfaces of the upper mounting plates 18 are threaded with second mounting bolts 19 that are compatible with the second threaded holes. The second mounting bolts 19 serve to fix the protective box 3 and the protective cover 4, making it convenient to inspect and maintain the mining motor 2 inside the protective box 3.
[0030] A bearing 20 is fixedly connected to the front of the protective cover 4. A coupling 21 is rotatably connected inside the bearing 20. The coupling 21 is used to connect the power end of the mining motor 2 and other transmission components to realize the transmission of power. The coupling 21 is fixedly installed on the power end of the mining motor 2. The mining motor 2 outputs power to other equipment through the coupling 21 to drive the operation of the coal mine production equipment.
[0031] The fixing assembly includes support seats 22 fixedly connected to both ends of the lower surface of the base 1. Each support seat 22 has a groove at its lower end, and two movable blocks 24 are movably connected inside each groove. The surfaces of the movable blocks 24 are smoothed to reduce friction with the inner walls of the grooves. Two fixing plates 25 are fixedly connected to the lower ends of the four movable blocks 24. The fixing plates 25 are made of high-strength metal material, possessing sufficient load-bearing capacity to support the weight of the coal mine electromechanical equipment and safety isolation devices. They are fixedly connected to the movable blocks 24 by welding, ensuring a strong connection. Third threaded holes are provided on both sides of the upper surface of each fixing plate 25, and third mounting bolts 28, matching the third threaded holes, are threaded onto both sides of the upper surface of each fixing plate 25. A threaded screw 26 is rotatably connected inside one of the grooves, and the two movable blocks 24 have openings that correspond to the threaded screw 26. The two adjusting bolt holes 27 are matched and have opposite threads. This opposite thread design allows the two movable blocks 24 to move in opposite directions along the threaded screw 26 when the screw 26 rotates, thereby achieving precise adjustment of the distance between the two fixed plates 25 to accommodate different sizes of mounting brackets. The lower ends of the two fixed plates 25 are fixedly connected to buffer pads 29, which are fixedly connected to the fixed plates 25 by adhesive, ensuring the firmness of the buffer pads 29. A knob 30 is rotatably connected to one side of one of the support seats 22. The knob 30 is connected to the threaded screw 26. By rotating the knob 30, the threaded screw 26 can be directly driven to rotate. A heat-conducting patch 23 is fixedly installed on the inner wall of the water-cooling jacket 5. The heat-conducting patch 23 is made of graphene. The graphene heat-conducting patch 23 can quickly conduct the heat generated by the mining motor 2 to the coolant, ensuring the normal operation of the mining motor 2.
[0032] In use, the mining motor 2 is fixedly installed inside the protective box 3, which is fixed to the middle of the upper surface of the base 1. The protective cover 4 is fixed to the upper end of the protective box 3. In the circulation assembly, the micro pump 9 is installed in the first mounting groove at one end of the upper surface of the protective cover 4. The micro pump 9 draws coolant from the cooling box 6 through the inlet pipe 10 and delivers it to the water-cooling jacket 5 fitted onto the surface of the mining motor 2 through the outlet pipe 11. The inner wall of the water-cooling jacket 5 is fitted with a graphene thermally conductive patch 23, which can quickly conduct the heat generated by the mining motor 2 to the coolant. The coolant that absorbs heat is delivered to the circulation box 7 through the circulation pipe 12. Several cooling pipes 8 connected to the back of the circulation box 7 deliver the coolant back to the cooling box 6, realizing the circulation of the coolant. At the same time, several cooling fans are fixedly installed in the second mounting groove of the mounting base 13 at one end of the upper surface of the base 1. 14. Upon startup, the mining motor 2 is cooled by air through several heat dissipation slots 16 on the back of the protective box 3, and the cooling pipe 8 is cooled to accelerate the cooling speed of the coolant. The lower mounting plates 17 on both sides of the protective box 3 and the upper mounting plates 18 on both sides of the protective cover 4 are connected by the second mounting bolts 19 to fix the protective box 3 and the protective cover 4. Finally, the threaded screw 26 is rotated by the knob 30. Since the threads of the two adjusting bolt holes 27 are opposite, the two movable blocks 24 will move in opposite directions or away from each other along the threaded screw 26, so that the fixing plate 25 can be precisely adjusted according to the width of the mounting frame, which improves the adaptability of the device to motor mounting frames of different widths. The front of the protective cover 4 is fixedly installed with the power end of the mining motor 2 through the coupling 21 rotatably connected by the bearing 20 to achieve power output.
