Description

Technical Field

[0001] The utility model belongs to the technical field of substation fire safety, and particularly relates to a substation fire safety device. Background Art

[0002] A substation is a crucial component in the power system, mainly responsible for voltage and current transformation, as well as the reception and distribution of electric energy. Substation equipment usually has a long service life and long operating time, making problems such as equipment wear, corrosion, and power loss increasingly complex and serious. These aging devices may experience short circuits or overloads, thus triggering fires. Therefore, automatic fire extinguishing devices are usually installed in substations. Among them, the fire detection tube automatic fire extinguishing device is a frequently used fire extinguishing device. The substation fire detection tube automatic fire extinguishing device is an independent automatic fire extinguishing system that realizes automatic fire detection and extinguishing through a pressurized fire detection tube and a set of fire detection bottle groups. The fire detection tube is ingeniously arranged above the possible location of the fire source. It relies on many detection points (linear type) along the fire detection tube for omnidirectional detection. Once a fire source is detected, the fire detection tube will be quickly softened and burst at the high-temperature part, releasing the fire extinguishing medium. After receiving the detection signal, the controller will quickly open the fire extinguishing bottle head valve, releasing the fire extinguishing agent and its driving gas in the storage bottle. These fire extinguishing agents are transported through the pipeline to the fire area and sprayed out by the nozzle, thus achieving the effect of quickly extinguishing the fire.

[0003] The problem existing in the prior art is that the container storing the fire extinguishing agent needs to be frequently inspected and replaced during long-term operation to ensure its normal operation and safety. However, the container is usually directly installed on the surface of the substation cabinet using screws and fixing straps, making the inspection and replacement work overly cumbersome.

A fixed rod 9 is fixedly connected to the rear side of the linkage rod 8. A linkage arm 10 is arranged on the front side of the fixed rod 9.

[0026] Adopting the above solution: By setting the linkage rod 8, when the linkage rod 8 is pulled, the linkage rod 8 can slide in the linkage groove 6 to drive the fixed rod 9 to move synchronously, thereby driving the linkage arm 10 to rotate.

[0027] Reference Figure 4 , the middle of the linkage arm 10 is rotationally connected to the inner wall of the fixed block 3 through a rotating shaft. The rear side of the linkage arm 10 is attached to the surface of the fixed rod 9. A sliding groove 11 is formed on the surface of the linkage arm 10. A moving rod 12 is sleeved in the sliding groove 11. A sliding rod 13 is arranged at the bottom of the linkage arm 10.

[0028] Adopting the above solution: By setting the linkage arm 10, when the fixed rod 9 moves, it squeezes the surface of the linkage arm 10 to drive the linkage arm 10 to rotate. When the linkage arm 10 rotates, it squeezes the moving rod 12 through the sliding groove 11, thereby driving the moving rod 12 to move.

[0029] Reference Figure 4 , both ends of the sliding rod 13 are fixedly connected to the front and rear sides of the inner wall of the fixed block 3 respectively, and the sliding rod 13 cooperates with the moving rod 12.

[0030] Adopting the above solution: By setting the sliding rod 13, when the moving rod 12 drives the moving block 14 to move, it can slide according to the stroke provided by the sliding rod 13.

[0031] Reference Figure 4 , the outer surface of the moving rod 12 is attached to the inner wall of the sliding groove 11.

[0034] Adopt the above solution: By setting the fixed arm 16, when the fixed arm 16 moves, it can slide in the moving groove 7, and at the same time move away from the connection groove 504 to release the fixed limit on the positioning block 503.

[0035] Working principle of the utility model:

[0036] When in use, pull the linkage rod 8 forward. The linkage rod 8 slides in the linkage groove 6 and drives the fixed rod 9 to move. During the movement of the fixed rod 9, it squeezes the linkage arm 10, causing the linkage arm 10 to rotate. While rotating, it squeezes the movement of the moving rod 12 through the sliding groove 11. The moving rod 12 simultaneously drives the moving block 14 to slide on the surface of the sliding rod 13. The moving block 14 slides and compresses the fixed spring 15, and at the same time drives the fixed arm 16 to move backward, thereby moving away from the connection groove 504 and releasing the fixed limit on the positioning block 503. Subsequently, rotate the positioning arm 502 and remove the fire extinguishing agent container 101 to perform maintenance work or replacement operation on it. After completion, place the fire extinguishing agent container 101 back on the base 5, and rotate the positioning arm 502 to secure the fire extinguishing agent container 101. Pull the linkage rod 8 again so that the positioning block 503 can be inserted into the positioning groove 501. Then release the linkage rod 8 to reset the fixed spring 15, and push the moving block 14 to slide forward, driving the fixed arm 16 to move and be inserted into the connection groove 504, thereby fixing and limiting the positioning arm 502 through the positioning block 503 to complete the installation and fixation of the fire extinguishing agent container 101.

[0037] In summary: For this substation fire safety device, through the coordinated work of the cabinet 1, the connection structure 2, the fixed block 3, and the fixing component 4, it solves the problem that the container storing the fire extinguishing agent needs to be frequently maintained and replaced during long-term operation to ensure its normal operation and safety. However, the container is usually directly installed on the surface of the substation cabinet using screws and fixing straps, making the maintenance and replacement work too cumbersome.
