[0003] The working space in the mine is often relatively narrow, and mobile equipment and transport vehicles may collide with the electric control box during operation. The traditional electric control box housing usually focuses on explosion-proof performance in its structural design, and relatively insufficient consideration is given to shock absorption and protection capabilities.

[0026] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the implementation manners of the present utility model in detail with reference to the attached drawings.
[0027] Please refer to Figures 1-4As shown in the figure, this embodiment is a mine explosion-proof electric control box housing, including an electric control box structure 1. A forward shock-absorbing structure 2 is provided at the connection of the electric control box structure 1. The forward shock-absorbing structure 2 can provide front-forward shock protection for the electric control box structure 1. Side protection structures 3 are fixedly connected to both side walls of the electric control box structure 1. The two side protection structures 3 can provide side protection for the electric control box structure 1. A leakage detection device 4 is also provided inside the electric control box structure 1. The leakage detection device 4 can detect leakage in the electric control box structure 1 and will give an alarm when leakage is detected. The forward shock-absorbing structure 2 can absorb the impact force from the forward impact on the electric control box structure 1, thereby realizing the forward protection of the electric control box structure 1. The side protection structures 3 can absorb the impact force from the impacts on both sides of the electric control box structure 1, thereby realizing the protection of both sides of the electric control box structure 1. The leakage detection device 4 can monitor leakage in the electric control box structure 1 and give an alarm when leakage occurs.
[0028] The electric control box structure 1 includes an electric control box body 101. A door panel 102 is hinged to the front of the electric control box body 101. A handle 103 is fixedly connected to the front of the door panel 102. A first magnet 104 is fixedly connected to the back side wall of the door panel 102. Electric control components 105 are provided inside the electric control box body 101. A second magnet 106 is provided on the inner side wall of the electric control box body 101 near the right side. The second magnet 106 is connected to the first magnet 104.
[0029] The front shock-absorbing structure 2 includes two upper and lower connecting seats 201. Two slide rail bodies 202 are provided on each of the two upper and lower connecting seats 201. Limiting grooves 203 are provided on both side walls of the four slide rail bodies 202. Slide block bodies 204 are provided in the four slide rail bodies 202 and the limiting grooves 203. A back plate 205 is connected between the two upper and lower connecting seats 201. A number of buffer springs 206 are fixedly connected to the front surface of the back plate 205. When the electric control box structure 1 encounters a frontal impact, the impact force first acts on the slide block and slide rail system. The cooperative design of the slide rail body 202 and the slide block body 204 allows the electric control box structure 1 to generate a certain relative displacement within the front shock-absorbing structure 2, thereby converting part of the impact energy into the kinetic energy of the electric control box structure 1. At the same time, this relative displacement also creates conditions for the compression of the buffer springs 206. The electric control box structure 1 will be stressed and displace backward through the front shock-absorbing structure 2. At this time, the electric control box structure 1 will slide through the slide block body 204 within the slide rail body 202 and the limiting groove 203, and squeeze the buffer springs 206 backward. At this time, the buffer springs 206 are stressed. The buffer springs 206, as the main energy-absorbing components, are gradually compressed during the displacement process of the electric control box structure 1. According to Hooke's law, the compression amount of the spring is proportional to the force applied. Therefore, a large amount of elastic potential energy is stored in the buffer springs 206 during the compression process. In this process, the impact energy is gradually converted into the elastic potential energy of the springs. When the impact force disappears, the elastic potential energy stored in the buffer springs 206 begins to be released, pushing the electric control box structure 1 back to the initial position along the slide block body 204 and the slide rail body 202. During this rebound process, due to the damping effect of the buffer springs 206 and the friction between the slide rail body 202 and the slide block body 204, part of the energy is converted into heat and dissipated, so that the electric control box finally stabilizes, realizing the effective absorption and buffering of the oncoming impact energy.
[0030] The side protection structure 3 includes an arc-shaped rubber part 301. A number of grooves 302 are provided on the side surface of the arc-shaped rubber part 301. Reflective strips are installed inside the number of grooves 302.
[0031] The leakage detection device 4 includes a leakage detector 401. A connecting wire 402 is provided at the connection of the leakage detector 401. A detection contact 403 is provided at the connection of the connecting wire 402. The detection contact 403 is connected to the bottom inside the main body 101 of the electric control box. When the electric control box structure 1 leaks electricity, the connecting wire 402 of the side protection structure 3 will detect abnormal current changes in the circuit. These changes are captured by the sensor and transmitted to the internal processing circuit. The processing circuit compares and analyzes the detected current signal with a preset safety threshold. Once it is determined that there is a leakage situation, the alarm mechanism is immediately triggered, causing the alarm light 404 to start flashing. After seeing the alarm light 404 flashing, the staff can quickly realize that there is a leakage fault and take corresponding measures, such as cutting off the power supply, carrying out repairs and maintenance, etc., to ensure the safety of personnel and the normal operation of the equipment.
[0032] The leakage detection device 4 further includes two alarm lights 404. The alarm lights 404 are electrically connected to the leakage detector 401, and both alarm lights 404 are installed on the tops of two arc-shaped rubber parts 301.
[0033] Working principle:
[0034] When the electric control box structure 1 encounters a frontal impact, the impact force first acts on the slider-rail system. The cooperative design of the rail body 202 and the slider body 204 allows the electric control box structure 1 to generate a certain relative displacement within the front shock absorption structure 2, thereby converting part of the impact energy into the kinetic energy of the electric control box structure 1. At the same time, this relative displacement also creates conditions for the compression of the buffer spring 206. The electric control box structure 1 will be stressed and displace backward through the front shock absorption structure 2. At this time, the electric control box structure 1 will slide through the slider body 204 within the rail body 202 and the limit groove 203 and squeeze the buffer spring 206 backward. At this time, the buffer spring 206 is stressed. As the main energy-absorbing component, the buffer spring 206 is gradually compressed during the displacement of the electric control box structure 1. According to Hooke's law, the compression amount of the spring is proportional to the force it receives. Therefore, a large amount of elastic potential energy is stored in the buffer spring 206 during the compression process. During this process, the impact energy is gradually converted into the elastic potential energy of the spring. When the impact force disappears, the elastic potential energy stored in the buffer spring 206 begins to be released, pushing the electric control box structure 1 back to the initial position along the slider body 204 and the rail body 202. During this rebound process, due to the damping effect of the buffer spring 206 and the friction between the rail body 202 and the slider body 204, part of the energy is converted into heat and dissipated, so that the electric control box finally stabilizes, achieving effective absorption and buffering of the oncoming impact energy.
[0035] The shock absorption principle of the side protection structure 3 is mainly based on the high elasticity and damping characteristics of the rubber material. When the electrical control box structure 1 is impacted from the side, the arc-shaped rubber block first contacts the impacting object. Due to the low elastic modulus of the rubber, it can rapidly undergo large deformations when subjected to external forces, so as to fully absorb the impact force and achieve the protection of the electrical control box structure 1.
[0036] When the electrical control box structure 1 has a leakage, the connection wire 402 of the side protection structure 3 will detect the abnormal current changes in the circuit. These changes are captured by the sensor and transmitted to the internal processing circuit. The processing circuit compares and analyzes the detected current signal with a preset safety threshold. Once it is determined that there is a leakage situation, the alarm mechanism is immediately triggered, causing the alarm light 404 to start flashing. After seeing the alarm light 404 flashing, the staff can quickly realize that there is a leakage fault and take corresponding measures, such as cutting off the power supply, carrying out repairs and maintenance, etc., to ensure the safety of personnel and the normal operation of the equipment.
