Description

Technical Field

[0001] This utility model relates to the field of drainage structures, and in particular to a rapid drainage structure for emergency drainage of underground powerhouses in hydropower stations. Background Technology

[0002] Hydropower stations are designed with drainage ditches and pipes in their underground powerhouses for organized drainage. However, after the generating units are put into operation, there may be some unpredictable water sources, such as bedrock seepage or equipment condensate. If these unidentified water sources are not discharged through existing drainage facilities, they can affect the safe operation of the power generation equipment, necessitating emergency drainage.

[0003] This necessitates the use of rapid drainage structures, such as the rapid drainage structure for emergency drainage in underground powerhouses of hydropower stations, as disclosed in prior art (CN 219793972U). This structure utilizes pre-embedded pipes embedded within the floor slab. An emergency drainage pipe is cast and fixed to the center of these pre-embedded pipes via a casting structure. The top of both the emergency drainage pipe and the casting structure features a recessed design, with the inlet of the emergency drainage pipe located at the center of the recessed structure. A flexible drainage hose is connected to the bottom of the emergency drainage pipe. This structure effectively utilizes existing pre-embedded pipes in the underground powerhouse to implement a rapid emergency drainage system. It can effectively divert and treat unknown water sources in emergencies, achieving organized discharge and ensuring the safe operation of power generation equipment while also improving the environment.

[0004] However, in practical applications, this drainage structure has revealed obvious defects. The operating environment of hydropower stations is relatively complex, with a large amount of dust inside the plant and various impurities generated during equipment operation. Due to the lack of an effective filtration device, dust and impurities can easily enter the drainage pipe with the water flow when drainage operations are carried out. These impurities gradually accumulate in the drainage pipe, which will lead to blockage. Once the drainage pipe is blocked, the drainage efficiency will be greatly reduced, or even completely unable to drain, seriously affecting the normal progress of subsequent drainage work and posing a potential threat to the safe and stable operation of the hydropower station.

[0005] Therefore, it is necessary to provide a rapid drainage structure for emergency drainage of underground powerhouses in hydropower stations to solve the above-mentioned technical problems. Utility Model Content

[0034] The top of the drain pipe 2 is fixedly installed on the inner side of the connecting ring 12.

[0035] The top cover 3 is disposed on the inner side of the groove 13, and the top of the top cover 3 has a plurality of through slots 31.

[0036] The filter frame 41 is disposed on the inner side of the collection frame 11. A plurality of support rods 43 are fixedly installed at the bottom of the filter frame 41. The bottom of the support rods 43 abuts against the bottom of the inner side of the collection frame 11. A fixing rod 44 is fixedly installed on the inner side of the filter ring 42.

[0037] The collection box 11 allows for the collection of water during use; the connecting ring 12 facilitates the installation of the collection box 11 and the drain pipe 2; the groove 13 facilitates the installation of the top cover 3; and the through groove 13 on the top of the top cover 3 allows for the rapid discharge of water to the inner side of the collection box 11.
