Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to a fire protection device for a remote control box of a substation. Background Art

[0002] With the rapid development of electrification in my country in recent years, there are increasingly higher requirements for ensuring the safe operation of the power system and improving the economic benefits of the system. In particular, the transformer control box needs to be protected. Once a fire hazard occurs, the flame enters the control box, causing damage to the components in the control box, which will cause failures and even serious accidents. The cable fireproofing of the transformer control box has also become an important part of the fire protection system in safe operation.

[0003] In the prior art, there is a cable fireproof plugging device for a transformer control box with a Chinese patent number of CN213879178U, which includes a mounting plate, a blocking box fixedly connected to the front of the mounting plate, a sealed cabin fixedly connected to the left and right sides of the blocking box, two fixed blocks fixedly connected to the top of the blocking box, and a screw rod movably connected to the top of the two sealed cabins, one end of which penetrates and extends into the sealed cabin and is movably connected to the inner bottom wall of the sealed cabin. The cable fireproof plugging device for the transformer control box, by setting a limit rod, the two movable blocks at the top and the two movable blocks at the bottom respectively drive the sealing ring to move toward the side close to the cable body, so that the two sealing rings on the left squeeze each other, and the two sealing rings on the right squeeze each other, thereby improving the sealing performance of the cable body for fireproof plugging, and preventing moisture, water and even insects from entering through the gap to cause safety hazards.

[0004] However, in the prior art, although the above patent has the above technical advantages, the disadvantage is that the equipment can only be protected at a fixed point and cannot be easily disassembled. For example, when a fire occurs, the equipment at the disaster site is damaged, and the fire protection devices elsewhere need to be disassembled to protect the equipment at the disaster site. In addition, although the above patent can achieve sealing performance, it cannot protect the internal electrical appliances from the high temperature generated during a fire, and the electrical appliances will still be damaged by the high temperature in a high temperature environment.

[0025] Working principle:

[0026] When in use, when a fire occurs, the main housing 1 of the device plays a fire prevention role. When the flame roasts the main housing 1, the flame forces the water inside the main housing 1 to boil, generating water vapor. The water vapor is ejected through the jet nozzle 3. When the water vapor is sprayed onto the blade 11 fixed on the outer surface of the transmission shaft 12, the blade 11 is forced to rotate. At the same time, a guide plate 4 is provided below the blade 11. When the water vapor is sprayed onto the surface of the blade 11, the generated distilled water falls onto the outer surface of the guide plate 4, flows into the guide pipe 5 along the groove in the guide plate 4, and flows back into the main housing 1 through the guide pipe 5. When the blade 11 drives the transmission shaft 12 to rotate, the housing 1 is driven 0, the impeller 13 is fixed on the outer surface of the impeller 14, thereby driving the impeller 13 to rotate. When the impeller 13 rotates, the coolant in the housing 10 is driven to flow. According to the special shape of the impeller 13, when the impeller 13 rotates, centrifugal force is generated, forcing the coolant in the water inlet pipe 9 to be drawn into the water outlet pipe 8. Under the continuous rotation of the impeller 13, the coolant is forced to enter the cooling pipe 7. The cooling pipe 7 is fixed on the outer surface of the fixing block 6. The fixing block 6 is connected to the main housing 1. At the same time, the fan blades 15 are connected below the transmission shaft 12. The transmission shaft 12 drives the fan blades 15 to rotate, thereby continuously cooling the coolant in the water inlet pipe 9 and the water outlet pipe 8.

The top ball 19 and the base 2 are connected by a top spring 20. Under the elastic force of the top spring 20, the top ball 19 is forced to support the hole above the base 2. When the base 2 completely slides into the main shell 1, the top ball 19 contacts the plug block 18. Under the interaction of the top ball 19 and the plug block 18, the base 2 is connected to the main shell 1.
