Therefore, the existing distribution cabinet needs to be improved to a certain extent. Utility Model Content

[0027] The specific implementation method is as follows: by setting a temperature sensor 4, a gear rod 6 and a gear 10, the temperature sensor 4 is used to drive the piston rod 5 to rise and fall through the temperature change inside the cabinet 1. At this time, the piston rod 5 drives the gear 10 to rotate through the gear rod 6, so that the gear 10 drives the adjusting wheel 13 to rotate through the transmission rod 11, so that the No. 2 adjusting rod 17 is stretched by the adjusting wheel 13 in cooperation with the No. 1 adjusting rod 15, and then the No. 2 adjusting rod 17 drives the No. 2 bearing frame 19 to switch the control switch 20, which solves the problem that the existing distribution cabinet cannot extinguish the fire source inside the distribution cabinet in the first time, thereby facilitating the overall device to extinguish the fire through the temperature change inside the distribution cabinet in the first time, and at the same time preventing the internal components of the distribution cabinet from being damaged by high temperature, thereby improving the safety of the internal parts of the distribution cabinet and reducing the cost of subsequent maintenance of the distribution cabinet by the staff.

[0028] See also Figure 1-4The utility model provides a technical solution: a fireproof power distribution cabinet, the inner wall of the adjusting wheel 13 is fixedly connected with a connecting rod 14, and the outer wall of the connecting rod 14 is movably connected with a No. 1 adjusting rod 15, the inner wall of the No. 1 adjusting rod 15 is fixedly connected with a bearing rod 16, and the outer wall bearing of the bearing rod 16 is connected with a No. 2 adjusting rod 17, the other end of the No. 2 adjusting rod 17 is fixedly connected with a mounting ring 18, and the inner wall bearing of the mounting ring 18 is connected with a No. 2 bearing frame 19, the other side of the No. 2 bearing frame 19 is fixedly connected with a control switch 20, and the inner wall of the control switch 20 is installed with a transmission line 21, and the other end of the transmission line 21 is installed with a dry ice storage tank 22, the inner wall of the cabinet 1 is installed with a shunt pipe 24, and the inner wall of the shunt pipe 24 is penetrated by a nozzle 25.

[0029] The dry ice storage tank 22 forms an integrated structure with the control switch 20 through the transmission line 21, and a delivery pipe 23 is installed through the inner wall of the dry ice storage tank 22, and a shunt pipe 24 is installed at the other end of the delivery pipe 23;

[0030] The shunt pipe 24 forms an integrated conveying structure with the dry ice storage tank 22 through the conveying pipe 23 . There are a plurality of nozzles 25 , and the nozzles 25 are installed at equal distances through the inner wall of the shunt pipe 24 .

[0031] The specific implementation method is as follows: by setting a control switch 20, a dry ice storage tank 22 and a shunt pipe 24, the control switch 20 is used to start the dry ice storage tank 22 through the transmission line 21. At this time, the dry ice storage tank 22 transports the fire-extinguishing dry ice to the shunt pipe 24 through the delivery pipe 23, so that the multiple nozzles 25 installed through the inner wall of the shunt pipe 24 can extinguish the fire inside the cabinet 1, thereby facilitating the staff to quickly extinguish the fire source inside the cabinet 1, improving the efficiency of the staff in extinguishing the fire source inside the cabinet 1, and at the same time, extinguishing the fire through dry ice, thereby reducing the damage to the internal components of the cabinet 1 during fire extinguishing, thereby increasing the practicality of the overall device.

[0032] Working principle: When using the fireproof power distribution cabinet, first install the dry ice storage tank 22 on the inner top wall of the cabinet 1. When a fire occurs in the cabinet 1, the temperature sensor 4 changes through the temperature inside the cabinet 1, so that the temperature inside the temperature sensor 4 rises and pushes the piston rod 5 through steam, thereby driving the gear rod 6 to rise and fall through the piston rod 5, and then driving the gear rod 6 to slide along the slide rail 9 fixed on one side of the fixing frame 8;

[0033] At this time, the gear rod 6 compresses the reset spring 7, and at the same time, the gear rod 6 drives the meshing gear 10 to rotate, thereby driving the transmission rod 11 to rotate through the gear 10, and then driving the adjustment wheel 13 fixed on the outer wall to rotate through the transmission rod 11. Since one side of the adjustment wheel 13 is connected to the first adjustment rod 15 through the connecting rod 14, when the adjustment wheel 13 rotates, the first adjustment rod 15 is pulled through the connecting rod 14;

[0034] At this time, the No. 1 adjusting rod 15 drives the No. 2 adjusting rod 17 to move up and down through the bearing rod 16, so that the No. 2 adjusting rod 17 rotates along the No. 2 bearing frame 19 through the mounting ring 18, thereby pulling the control switch 20 through the No. 2 bearing frame 19, and then starting the dry ice storage tank 22 through the transmission line 21 installed on one side of the control switch 20;

[0035] At this time, the dry ice storage tank 22 transports the dry ice to the shunt pipe 24 through the delivery pipe 23, so that the shunt pipe 24 can evenly spray the dry ice through the nozzle 25 to extinguish the fire source inside the cabinet 1. When the temperature inside the cabinet 1 cools down, the reset spring 7 elastically deforms, and at this time, the reset spring 7 drives the gear rod 6 to rise and fall, and at the same time, the No. 2 bearing frame 19 pulls the control switch 20 again to complete the closing of the dry ice storage tank 22.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
