Description

Technical Field

[0001] This utility model relates to the field of equipment inspection technology, and in particular to a safety inspection device for mine electrical equipment. Background Technology

[0002] With the development of technology, many mines rely on electrical equipment for operation. This equipment is generally controlled by electrical meters. Existing electrical meters in mines are usually installed outdoors. To ensure the normal operation of the electrical equipment, the meters need to be inspected regularly. As an important power and control core in mine operations, the operating status of mine electrical equipment is directly related to the safety and production efficiency of underground operations. However, the operating conditions in mines are limited by the high dust, high humidity, high temperature difference and complex gas composition.

[0003] However, existing mine electrical equipment safety inspection devices cannot effectively collect and utilize rainwater during use, making it difficult to effectively collect and dissipate heat from rainwater. This results in less than ideal convenience of use for existing mine electrical equipment safety inspection devices. Therefore, a mine electrical equipment safety inspection device is provided to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety inspection device for mine electrical equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safety inspection device for mine electrical equipment, comprising an inspection box, fixing plates on both sides of the inspection box, a switch door in the middle of one end of the inspection box, an assembly plate at the bottom of the inspection box, an equipment inspection mechanism at the top of the assembly plate, and a filter plate at the bottom of the inspection box.

[0006] As a further description of the above technical solution: the inspection box includes a box body disposed at one end of the switch door, a support rod disposed at the top of the box body, an inclined plate disposed at the top of the support rod, water storage cavities disposed on both sides of the box body, an arc-shaped surface disposed at the top of the water storage cavity, a water inlet hole disposed at the top of the arc-shaped surface, and the water inlet hole cooperates with the inclined plate, and a sealing plate disposed at the bottom of the water storage cavity. The cooperation between the support rod and the inclined plate enhances the structural strength of the box body, while the inclined plate guides water flow into the water inlet hole to prevent water from accumulating on the surface of the equipment. Rainwater is collected and stored in the water storage cavity as a redundant measure for cooling, heat insulation or explosion-proof safety. The arc-shaped surface design reduces the accumulation of fallen leaves and dust, and improves the efficiency of rainwater collection.

[0007] As a further description of the above technical solution: A placement cavity is provided in the middle of the housing; several ventilation holes are provided at the top of the placement cavity; a temperature sensor is provided at the bottom inner side of the placement cavity; several placement frames are provided on the outer circumference of the temperature sensor; several heat dissipation holes are provided on one side of each placement frame; placement blocks are provided at the four inner corners of the placement cavity; placement holes are provided at the top of each placement block and these placement holes cooperate with the assembly plate; several exhaust holes are provided at the bottom of the placement cavity; the housing also includes a filter cavity opened at the bottom of the placement cavity, and the filter cavity cooperates with the exhaust holes; several ventilation holes are provided at the bottom of the filter cavity. The filter chamber has a vent hole, and a limiting groove is provided at the end away from the switch door. The limiting groove cooperates with the filter plate. Through the cooperation of the placement chamber and the ventilation hole, the air inside the chamber is kept circulating, maintaining a stable operating temperature of the testing equipment. A temperature sensor is used to monitor temperature changes in real time, avoiding test errors or equipment damage caused by temperature rise. At the same time, the cooperation of the placement frame and heat dissipation holes not only fixes the tested equipment but also enhances heat dissipation and improves equipment durability. Through the cooperation of the exhaust hole, filter chamber and vent hole, a multi-layer filtration and exhaust system is formed to effectively prevent the leakage of harmful gases or dust, while purifying the exhaust gas and ensuring the safety of the mine environment.

[0008] As a further description of the above technical solution: the top of the assembly plate is provided with several through holes, and the four corners of the assembly plate are provided with assembly holes. The assembly holes and the placement holes are connected by assembly bolts. The through holes facilitate the laying of transmission channels for cables, wires, etc., improve heat dissipation efficiency, and improve the electrical connectivity and module expansion capability of the device. At the same time, the assembly holes and placement holes are connected by assembly bolts to ensure assembly firmness, facilitate equipment maintenance and module replacement, and enhance the flexibility and maintainability of the structure.

[0009] As a further description of the above technical solution: the filter plate includes a barrier plate disposed inside the filter chamber, and one end of the barrier plate cooperates with the limiting groove. A protective plate is disposed at the end of the barrier plate away from the limiting groove, and a handle is disposed at the end of the protective plate away from the barrier plate. The protective plate cooperates with the filter chamber, and the protective plate is made of flexible material. Through the cooperation of the barrier plate and the limiting groove, the filter assembly is stably positioned and not easily displaced, thereby improving the overall filtration effect. The protective plate also prevents impurities from entering the main chamber and prevents the operator from directly contacting the filter material, thus enhancing personal safety. The protective plate is made of flexible material, which makes it easy to absorb vibration and reduce the risk of scratching or damaging other components during maintenance.

This improves the practicality and stability of the whole machine in outdoor environments with high dust, high humidity, and high temperature differences. At the same time, the assembly plate set at the bottom of the inspection box forms an assembly platform that can be quickly disassembled and assembled through the precise matching of assembly holes and placement holes, improving the flexibility of equipment installation and system maintenance efficiency.

[0012] This utility model designs a safety inspection device for mining electrical equipment. The top of the inspection box features an inclined plate and support rod forming a stable protective cover, which, in conjunction with the water storage chambers on both sides, creates a natural rainwater drainage and collection system.

[0026] Working principle:

[0027] In the process of using the safety inspection device for mine electrical equipment provided by this utility model, relevant technicians first select the appropriate model of inspection box 1 according to the type of electrical equipment to be inspected and the testing requirements, and place it in the designated inspection area. The fixing plates 2 on both sides are used to firmly connect it to the wall or platform with bolts to ensure the installation stability and vibration resistance of the inspection device during operation. After the device is installed, the user opens the switch door 3 located at one end of the middle of the inspection box 1. The operator accurately places the electrical equipment to be inspected into the placement cavity 111 inside the box through the opening and fixes it on the assembly plate 4 at the bottom of the box. The assembly plate 4 is fixedly connected to the placement hole 117 in the placement cavity 111 through the assembly holes 42 at the four corners and the assembly bolts 43 to form a structural fit, ensuring that the equipment is positioned firmly and does not shake. At the same time, several through holes 41 opened on the top of the assembly plate 4 are used for the passage and laying of cables and test wires, which facilitates the formation of electrical connection paths and improves the connectivity and wiring convenience of the test path.

[0028] After the equipment enters the working state, the placement chamber 111 inside the inspection box 1 achieves natural ventilation through multiple ventilation holes 112 at the top, and the exhaust hole 118 at the bottom is connected to the filter chamber 119 located at the bottom. Combined with the multiple structural designs inside the filter chamber, including the ventilation hole 1110, the limiting groove 1111 and the detachable filter plate 6, the internal air is filtered to prevent harmful dust or gas from escaping, thus maintaining the cleanliness and safety of the mine working environment. The baffle plate 61 inside the filter plate 6 is precisely positioned by the limiting groove 1111, and its end is equipped with a flexible protective plate 62 and a handle 63. The protective plate not only isolates impurities but also prevents accidental contact with the internal filter medium during maintenance.

[0029] Meanwhile, the upper structure of the equipment inspection mechanism 5 works in concert with the inclined plate 13 and support rod 12 set on the top of the box 11, which not only enhances the overall stress stability of the box, but also forms a water collection and guiding structure with the inclined plate 13, which effectively guides external rainwater to the water storage chambers 14 set on both sides of the box. The rainwater enters the upper part of the arc-shaped surface 15 through the water inlet 16. After the arc structure reduces impurities such as leaves and soil clods, it enters the chamber. The bottom of the water storage chamber 14 is equipped with a sealing plate 17, which can be opened to drain the accumulated water during inspection or maintenance. The collected rainwater is used for subsequent cooling, heat insulation or explosion-proof emergency backup, which improves the safety performance of the device and the mine's ability to deal with emergencies. At the same time, the temperature sensor 113 inside the placement chamber 111 monitors the changes in the ambient temperature inside the box in real time. When the temperature exceeds the limit, an early warning signal is issued to prompt the operator to deal with it in time, thereby preventing equipment mis-inspection or damage due to overheating. The placement frame 114, together with the heat dissipation holes 115, not only stabilizes the equipment structure, but also enhances the rapid release of heat, effectively extending the service life of the inspection equipment.
