Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric power fire fighting, especially relates to a maintenance power supply box. BACKGROUND

[0002] In the operation process of the converter station (substation) equipment, the fire-fighting water reservoir must be in the state of full water storage to ensure that the fire-fighting system can be started at any time. In this case, if the new fire-fighting system pipeline is connected to the water pool, only underwater operation can be used to open holes in the pool wall. In the traditional fire-fighting water reservoir pressure opening operation, high-efficiency and safe operation under pressure environment is usually needed through the hole opening device. However, in the traditional fire-fighting water reservoir pressure opening operation, leakage water treatment is a key problem to be solved. The leakage water not only causes wet and slippery and dangerous working conditions for the construction environment, but also directly affects the stability of the water reservoir foundation. If the bottom and surrounding structure of the pool are exposed to the leakage water for a long time, water and soil loss or corrosion of concrete will cause the foundation structure to gradually deteriorate, and even eventually cause the foundation to be damaged. Especially during the pressure operation process, the leakage water pressure increases, which may aggravate the corrosion and damage of the foundation. SUMMARY

[0021] The inner wall of isolation pool 2 is provided with a waterproof layer to prevent water leakage generated in the process of pressure operation.The waterproof layer is made of high-strength waterproof material, such as polyurethane or epoxy resin coating, to ensure its water resistance and pressure resistance;Meanwhile, the reserved sleeve 3 is embedded in the inner wall of the isolation pool 2, which provides a channel for the subsequent installation of the fire pipeline, and ensures that the water flow between the fire reservoir 1 and the isolation pool 2 can be smoothly connected.The reserved sleeve 3 enables the fire pipeline to be connected with the fire reservoir 1 through the side wall of the isolation pool 2, ensuring that the fluid is not hindered.

[0022] The inner wall of the side of the isolation pool 2 close to the fire reservoir 1 is fixed with a steel pipe base 4, which is located at the predetermined tapping position and is concentrically arranged with the tapping position.The steel pipe base 4 has strong compression and tension resistance, which can effectively support the pressure in the tapping operation;The contact surface between the steel pipe base 4 and the inner wall of the isolation pool 2 is sealed by sealing glue to ensure the sealing performance.The sealing glue is made of high-performance polyurethane sealing glue, which can resist the water pressure in the pressure environment and prevent water leakage.The steel pipe base 4 is fixed to the inner wall of the isolation pool 2 by chemical bolts to ensure that it does not loosen or displace during pressure operation.

[0023] The end of the steel pipe base 4 away from the isolation pool is integrally provided with a flange 5 for connecting a stop valve 6 and a tapping device 7.The flange provides a connection interface with the stop valve 6 to ensure stable installation of the stop valve 6 and the tapping device 7.The flange 5 is integrally formed with the steel pipe base 4, avoiding the instability problem that may occur during later installation.

[0028] The working principle and operation steps of this utility model:

[0029] According to the requirements of the pressure drilling operation of the fire water tank, an isolation tank 2 is built at the location where the drilling is planned in the fire water tank 1 according to the space required for the drilling operation and connected to the original fire water tank 1. The newly built isolation tank 2 is cast into a whole with the fire water tank 1 using the solution of embedded reinforcement. The newly built isolation tank 2 needs to be waterproofed, and a reserved casing 3 for the current fire pipeline is reserved at the corresponding position of the tank body. The purpose of building this isolation tank 2 is to prevent leakage at the opening of the fire water tank 1. After the construction of the water tank and the current fire pipelines, valves, etc. is completed, the drilling operation is carried out, and the steel pipe base 4 with flange 5 is fixed to the side wall of the fire water tank 1, that is, the inner wall of the isolation tank 2, by chemical bolts. The steel pipe base 4 and the fire water tank 1 are bonded by structural adhesive, and the surrounding area is waterproofed by sealant.

[0030] Reference Figure 3 、 4 The pressurized tapping process involves installing a water stop valve 6 at flange 5 and keeping it open; installing a tank tapping device 7 and performing the tapping operation; a small amount of water leakage may occur during the tapping process; after the tapping is complete, remove the tapping device 7, close the water stop valve 6, and connect the fire protection pipe to the water stop valve via an elbow 9. Once the connection is complete, the water stop valve 6 can be opened to connect the fire protection system to the fire water reservoir 1. Since the steel pipe is connected to the concrete sidewall using chemical bolts and structural adhesive, leakage is possible, but it does not affect operation. The leaked water will be stored in the isolation tank, and a submersible pump installed at the bottom of the drainage collection chamber 8 will ensure smooth drainage of the leaked water.
