When the coal seam is far from the surface, it is generally chosen to excavate tunnels underground to extract coal. This is called an underground coal mine. Therefore, during the construction of a coal mine, it is necessary to connect the electromechanical equipment. Junction boxes are one of the electrical auxiliary materials. The wires pass through conduits, and junction boxes are used as transitions at the joints of the wires. The conduits are connected to the junction boxes, and the wires inside the conduits are connected in the junction boxes, which serves to protect and connect the wires.

A heat dissipation component extending into the box body 1 is detachably installed inside the heat dissipation box 2. A dust cover 5 is detachably installed at one end of the heat dissipation component located inside the box body 1.
[0023] When the coal mine electromechanical junction box is in use, the heat dissipation components on both sides of the box 1 are activated. The heat dissipation components can efficiently dissipate heat from the inside of the box 1. The rear end of the heat dissipation components is equipped with a filter plate 4, and the front end of the heat dissipation components is equipped with a dust cover 5. This can effectively prevent a large amount of dust from entering the inside of the box 1 and also facilitate the dust removal inside the box 1. At the same time, the filter plate 4 and the dust cover 5 are also easy to install, remove, replace or clean. The dust-blocking parts of the filter plate 4 and the dust cover 5 can be made of air-permeable dust-filtering materials available in the prior art.
[0024] In one embodiment, a fixing plate 6 for supporting the filter plate 4 is welded inside the cover 3. A fixing screw 7 is welded on the fixing plate 6. A collar 8 is slidably connected to the fixing screw 7. Two sets of stop bars 9 are integrally formed on the outer ring of the collar 8. A first knob 10 for locking the collar 8 is threadedly connected to the fixing screw 7. The filter plate 4 is snapped against the fixing plate 6. The collar 8 slides to the stop bars 9 on both sides and abuts against the filter plate 4. Rotating the first knob 10 can lock and fix the collar 8, which can facilitate the quick installation and removal of the filter plate 4.
[0025] The inner wall of the box cover 3 is welded with multiple sets of inclined baffles 11 arranged at equal intervals. The inclined baffles 11 are located on the side of the fixed plate 6 away from the heat dissipation components, which can conveniently protect the coal mine electromechanical junction box installed outdoors from rain, and at the same time provide shielding and protection for structures such as the filter plate 4.
[0026] In one embodiment, the connector includes two sets of fixing blocks 12 welded to the rear end of the heat sink 2. The interior of each of the two sets of fixing blocks 12 is hinged with a connecting block 13 welded to the cover 3. Specifically, the fastener includes two sets of upper and lower support plates 14 welded to the front end of the heat sink 2. A sleeve 15 is rotatably connected between the two sets of support plates 14. A fastening screw 16 is welded to the sleeve 15. A second knob 17 is threaded onto the fastening screw 16. Two sets of upper and lower positioning rods 18 are welded to the front end of the cover 3.

When the servo motor 22 is started, it drives the cooling fan 23 to rotate, and the cooling fan 23 can efficiently dissipate heat from the inside of the housing 1.
[0029] The support tube 20 is located inside the housing 1 and is connected to the dust cover 5 by a thread. This prevents the wiring inside the housing 1 from getting tangled with the cooling fan 23 and also facilitates further dust removal inside the housing 1. The side of the dust cover 5 is welded with a cross bar 24, which makes it easy for staff to rotate the dust cover 5 to install and remove it.
