The signal box 3 is located directly above the equipment housing 1. An adjustment mechanism 6 is located at the bottom of the signal box 3. The adjustment mechanism 6 adjusts the height of the signal box 3 according to the height of the coal mining tunnel to meet the needs of signal transmission and reception. An AC contactor 7 is installed inside the signal box 3. An air-cooling mechanism 12 is installed inside the equipment housing 1. The air-cooling mechanism 12 filters the intake air, so that the lighting control devices inside the signal box 3 can maintain a reasonable temperature during operation and avoid damage from high temperature.
[0022] In this embodiment, the adjustment mechanism 6 includes a signal housing 3, a vertical support arm 5, a fastener 10, a channel steel seat 11, a communication antenna 8, and a four-way WiFi remote control switch 9. The vertical support arm 5 is symmetrically arranged at the bottom of the signal housing 3, and the channel steel seat 11 is connected to the outside of the vertical support arm 5. The four-way WiFi remote control switch 9 is arranged inside the signal housing 3, and the communication antenna 8 is connected to the outside of the four-way WiFi remote control switch 9. The fastener 10 is connected through one side of the channel steel seat 11, and the top of the equipment housing 1 is connected through the bottom of the vertical support arm 5.
[0023] In this embodiment, the device housing 1 is connected to the vertical support arm 5 through symmetrically arranged channel steel seats 11 inside. The channel steel seats 11 are used to position the two sides of the vertical support arm 5, which facilitates the dynamic adjustment of the height of the signal box 3.
[0024] In this embodiment, the channel steel seat 11 is connected to the outside of the vertical support arm 5 through a through fastener 10, and the fastener 10 is inserted and positioned laterally through the channel steel seat 11.
[0025] In this embodiment, the air-cooling mechanism 12 includes a blower 13, a corrugated hose 14, an air filter 15, and an exhaust port 16. The blower 13 is located inside the signal box 3. The input end of the blower 13 is connected to the air filter 15, and the output end of the blower 13 is connected to one end of the corrugated hose 14. The exhaust ports 16 are evenly spaced at the top of the signal box 3. The blower 13 is installed between two sets of vertical support arms 5.
[0026] In this embodiment, the air filter 15, which is connected through the bottom of the device housing 1, is connected to the blower 13. The air filter 15 filters the intake air to prevent moisture in the air from affecting the operational stability of the electrical components.
[0027] In practical applications, this type of underground lighting control box for coal mining includes the following functions:
[0028] Step 1: Before use, according to the height of the coal mine tunnel, the operator pulls the vertical support arm 5 so that the vertical support arm 5 moves vertically at the top of the equipment housing 1, so that the signal box 3 connected to the top of the vertical support arm 5 fits with the top of the tunnel. The operator inserts the fastener 10 into the connection between the channel steel seat 11 and the vertical support arm 5 to lock it. At the same time, the power supply wire for the lamp is fixed at the top of the tunnel, and the power supply wire for the lamp is inserted into the inside of the signal box 3.
[0029] Step 2: The operator connects one end of the light switch button to the live wire and the other end to the common terminal of the four-way WiFi remote control switch 9. This is to enable remote control functionality. Connect the power cord of the four-way WiFi remote control switch 9 to the power supply, and connect the signal line of the receiver to the transmitter of the wireless transmitter. Connect the power cord of the four-way WiFi remote control switch 9 to the AC contactor 7, and connect the signal line of the wireless transmitter to the receiver. Connect the internal wireless transmission module of the four-way WiFi remote control switch 9 to the power supply, and ensure that the other end of the wireless transmission module is connected to the wall switch.
[0030] Step 3: When it is necessary to turn off the lights, the operator uses the corresponding APP set by the four-way WiFi remote control switch 9 to control the four-way WiFi remote control switch 9 and turn off the AC contactor 7. The AC contactor 7 has an electromagnet inside with a control coil. When the coil is energized, the AC contactor 7 is attracted (opened), and when the power is de-energized, the AC contactor 7 is released (closed). In this way, the main contacts and auxiliary contacts act synchronously, thereby turning off the lights.
[0031] Step 4: Simultaneously, the card slots of the four-way WiFi remote control switch 9 and the AC contactor 7 are powered by one end of the AC contactor 7 to power the blower 13. The blower 13 draws outside air into the air filter 15. After the air is filtered by the air filter 15, the flowing air is injected into the signal box 3 through the corrugated hose 14 connected to the output end to cool the internal equipment of the signal box 3. The hot air is then dissipated through the exhaust port 16.
[0032] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
