[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model discloses an electric automatic control safety device, comprising an electric automatic control box 1 and a safety device 2, wherein the electric automatic control box 1 comprises a box body 11, a box door 12, a base 13, a wiring rack 14 and a fixing frame 15, wherein the box door 12 is hingedly connected to the front end of the box body 11, the base 13 is welded to the bottom of the box body 11, and a wiring rack 14 is welded to the rear end of the box body 11, the wiring rack 14 is arranged in the box body 11, and the wiring rack 14 is used to arrange various lines of the electrical control box, the fixing frame 15 is welded on both sides of the box body 11, and the fixing frame 15 is used to fix the safety device 2, and the safety device 2 comprises an explosion-proof part 21, an anti-electric shock part 22, a dehumidification part 23 and a monitoring part 24, and the explosion-proof part 21 is arranged outside the box body 11, and the safe use of the equipment is guaranteed in an explosive environment with a high risk factor, and serious accidents such as fire caused by explosion or high temperature are prevented. The anti-electric shock part 22 is fixed in the box body 11, which prevents the occurrence of electric shock accidents and protects the life and property safety of the staff. A dehumidifier 23 is provided on the right side of the box 11, and the dehumidifier 23 is connected to the fixing frame 15 to prevent the insulation performance of the box 11 from being reduced due to excessive humidity, thereby causing leakage due to equipment failure. The monitoring unit 24 is embedded in the box door 12, and is used to monitor the internal situation of the electrical automatic control box 1, and can also monitor the temperature and humidity inside and outside the box 11 in real time. The outer bolts of the box door 12 are connected with an insulating handle 16. When the staff opens and closes the box door 12, the insulating handle 16 isolates the possibility of electric shock. The explosion-proof part 21 includes a flameless explosion vent 211 and a reflective plate 212. The flameless explosion vent 211 is bolted to the left side of the box body 11. The flameless explosion vent 211 is mainly composed of an explosion venting plate and a flameless discharge flame extinguishing net. When the flameless explosion vent 211 is operating normally, the explosion venting plate is in a closed state. Once a dust explosion occurs in the environment where the electrical automatic control box 1 is located, the force of the explosion overpressure on the explosion venting plate exceeds the opening pressure of the explosion venting plate, and the explosion venting plate will rupture and open along the seam, and the explosion pressure will leak out from the gap of the fire-blocking net, and the flame will be quenched by the "snuffling" effect of the flame extinguishing layer to prevent the explosion pressure and the high temperature generated by the flame from causing harm to the surrounding personnel and the electrical automatic control box 1. The flameless explosion vent 211 can not only effectively block flames and heat, provide a safe place for the electrical automatic control box 1, buildings and staff, but also effectively collect dust and reduce pollution to the environment. When the electric automatic control box 1 is operated outdoors, it is usually exposed to strong light, which causes the internal temperature of the electric automatic control box 1 to be too high, which may easily cause the internal components of the equipment to fail and performance to decline. Therefore, a reflector 212 is provided, which is embedded in the top of the box body 11. The reflector 212 prevents light from directly hitting the electric automatic control box 1, reduces the internal heat of the electric automatic control box 1, and avoids the internal components of the box body 11 from being damaged by high temperature. Figure 1 , Figure 2 .

[0025] The electrical automatic control equipment involves high-voltage power systems. Once a fault occurs, it may cause serious accidents such as fire or electric shock. Therefore, the equipment adds an anti-electric shock unit 22 to protect the life and property safety of the staff. The anti-electric shock unit 22 includes a water-immersion anti-electric shock protector 221 and a grounder 222. The AXB2-32-2LD water-immersion protector is connected to the right side of the box 11. The water-immersion anti-electric shock protector 221 is snapped onto the fixing frame 15. The water-immersion anti-electric shock protector 221 can effectively block the circuit. When a humid environment or water pollution causes electric shock to the equipment, the water-immersion anti-electric shock protector 221 can close the circuit in the shortest time, thereby preventing electrical accidents. There are three grounders 222, all arranged in an array at the bottom of the electrical automatic control box 1. The grounding device 222 includes a grounding rod 2221, a connecting piece 2222 and a grounding plate 2223. The bottom end of the grounding rod 2221 is embedded in the base 13. The grounding rod 2221 passes through the base 13 and the bottom of the box 11. The top of the grounding rod 2221 is set on the bottom of the box 11. The top of the grounding rod 2221 is fixed with a connecting piece 2222 to connect the line with the connecting piece 2222. The grounding plate 2223 is fixed to the bottom of the base 13. The bottom end of the grounding rod 2221 is welded to the grounding plate 2223. The grounding plate 2223 contacts the ground to introduce current into the ground. The grounding rod 2221 reduces the risk of the electrical automatic control box 1 being charged and reduces the possibility of electric shock injury. In addition, the grounding rod 2221 can protect the equipment from electromagnetic interference and static electricity, reducing the failure rate and maintenance cost of the equipment. See details. Figure 3 .

[0026] The long-term operation of the electrical automatic control box 1 in a high humidity environment will cause corrosion, rust and insulation aging of the electrical equipment components. Therefore, the equipment is added with a dehumidification unit 23, which includes a dehumidifier 231 and an alarm 232. The dehumidifier 231 is bolted to the fixing frame 15. The dehumidifier 231 can improve the humid environment in the box body 11 and extend the service life of the equipment. The alarm 232 is connected to the top of the dehumidifier 231. When the dehumidifier 231 detects that the humidity is high, the alarm 232 is controlled to sound an alarm. The monitoring unit 24 includes an explosion-proof glass 241 and a thermometer and hygrometer 242. The explosion-proof glass 241 is embedded in the box door 12. The explosion-proof glass 241 can monitor the internal situation of the electrical automatic control box 1 from the outside when the box door 12 is closed. The thermometer and hygrometer 242 is embedded in the box door 12 and is set below the explosion-proof glass 241. The hygrometer monitors the temperature and humidity inside and outside the box body 11 in real time to ensure that the electrical automatic control box 1 is maintained at a safe temperature and humidity. See Figure 4 .
