[0030] See attached document Figure 1 - Appendix Figure 6 This utility model provides a fire prevention device for electrical equipment, comprising:

[0033] Pipeline 2 5 is fixedly embedded in the rear side of gas storage tank 2. A hose 6 is fixedly connected between pipe 2 5 and pipe 1 4. An electronic switch valve 1 7 is installed on pipe 2 5. Pipeline 3 8 is fixedly connected between the two hollow shells 3 and gas storage tank 2. Electronic switch valve 2 9 is installed on both pipes 3 8.

[0034] Two U-shaped frames 10 are provided, and both U-shaped frames 10 are fixedly connected to the bottom of the base plate 1.

The central processing unit 13 is fixedly connected to the top of the base plate 1. The central processing unit 13 is electrically connected to the flame sensor 11, the smoke sensor 12, the electronic switch valve 7, and the electronic switch valve 9.

[0035] In this implementation plan, when the electrical equipment catches fire, the flame sensor 11 and the smoke sensor 12 detect it in time, and then the electronic switch valve 1 7 and the electronic switch valve 2 9 open, so that the carbon dioxide gas in the gas storage tank 2 can enter the pipe 1 4 and the hollow shell 3 and be sprayed onto the electrical equipment, so that there is no need for manual handheld fire extinguisher to extinguish the fire.

[0036] In order to achieve the purpose of gas filling, the device adopts the following technical solution: a gas filling pipe 14 is fixedly embedded on the front side of the gas storage tank 2, and a first switch valve 15 is provided on the gas filling pipe 14;

[0037] To achieve the purpose of reinforcement, the device adopts the following technical solution: two reinforcing rods 16 are fixedly connected between the two hollow shells 3 and the base plate 1.

[0038] To achieve the left-right movement of pipe 4, the device employs the following technical solution: Two support blocks 17 are fixedly connected to the bottom of the base plate 1. A reciprocating screw 18 is embedded in each support block 17. A sliding seat 19 is fitted around the reciprocating screw 18. The sliding seat 19 is connected to the reciprocating screw 18 via a ball screw pair. The sliding seat 19 is fixedly connected to the top of pipe 4. A motor 20 is fixedly connected to the top of the base plate 1. A rotating shaft 21 is fixedly connected to the output shaft of the motor 20. A [missing information - likely a device or component] is fixedly embedded on the base plate 1. There is a housing 22, one side of which is open. The rotating shaft 21 and one end of the reciprocating screw 18 both extend into the housing 22. The motor 20 is electrically connected to the central processing unit 13. The reciprocating screw 18 and the rotating shaft 21 are both fixedly fitted with sprockets 23. The two sprockets 23 are fitted with chains 24. The two sprockets 23 are connected by the chain 24. The chain 24 is located inside the housing 22. The design of the motor 20, chain 24, reciprocating screw 18 and other components allows the pipe 4 to move left and right.

[0039] In order to achieve the purpose of stable movement of the sliding seat 19, the following technical solution is adopted in this device: a limiting rod 25 is fixedly connected to the bottom of the base plate 1, the limiting rod 25 passes through the sliding seat 19 and slides in contact with it, and the limiting rod 25 can make the sliding seat 19 move stably left and right;

[0040] To achieve the purpose of installation, the device adopts the following technical solution: two mounting brackets 26 are fixedly connected to the top of the base plate 1, and two mounting brackets 26 are provided with two mounting holes.

[0041] In order to reduce wear, the device adopts the following technical solution: the reciprocating screw 18 and the support block 17 are connected by bearings, which can reduce wear.

[0042] The usage process of this utility model is as follows: When using this device, first open the first switch valve 15, and then fill the gas storage tank 2 with carbon dioxide gas through the gas filling pipe 14. During the filling process, the pressure in the gas storage tank 2 increases. After the filling is completed, close the first switch valve 15. Then, place this device in the distribution box containing electrical equipment, and then make the two hollow shells 3 contact the inner walls on both sides of the distribution box. Then, with the design of the mounting bracket 26 and the mounting hole, use bolts to install this device in the distribution box. In this way, this device can be fitted onto the outside of the electrical equipment.

[0043] When electrical equipment catches fire, the flame sensor 11 and the smoke sensor 12 will detect it in time and transmit the signal to the central processing unit 13. Then, the central processing unit 13 can control the electronic switch valve 7 and the two electronic switch valves 9 to open. Because the pressure in the gas tank 2 is relatively high, the carbon dioxide gas in the gas tank 2 can enter the pipe 4 and the two hollow shells 3 through the pipe 5, the hose 6, and the two pipes 8 and spray it on the electrical equipment, thereby isolating oxygen to achieve the effect of extinguishing the fire. In this way, there is no need for manual hand-held fire extinguishers to extinguish the fire, and the fire can be extinguished more promptly, which can prevent the fire from continuing to spread.

[0044] When the central processing unit 13 controls the opening of the electronic switch valve 7 and the two electronic switch valves 9, it can also control the motor 20 to work. The motor 20 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the chain 24 to rotate, and the chain 24 drives the reciprocating screw 18 to rotate. This allows the sliding seat 19 and the pipe 4 to move left and right continuously. This increases the spraying range of the pipe 4 when spraying carbon dioxide, thereby increasing the oxygen isolation effect.

[0045] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
