[0002] In industrial production, cooling towers are important heat exchange equipment and are widely used in industries such as power, chemical, and metallurgy. They are used to dissipate heat from circulating cooling water into the atmosphere. The drainage system is a key component of the cooling tower, and its stable operation directly affects the efficiency and lifespan of the cooling tower. In actual operation, the drainage pipe is easily blocked by the accumulation of impurities, scale, algae and other substances, resulting in poor drainage, or even equipment failure and increased maintenance costs.

[0003] Traditional cooling tower drain pipe structures typically employ simple filter screens or fixed filter devices. While these can intercept some impurities, the filter screens are prone to clogging after prolonged use, making cleaning and maintenance inconvenient and preventing real-time monitoring of drain pipe blockage.

The circulating water of the cooling tower enters the drainage tank 1 through the inlet 2. The water flow first passes through the filter plate 6, and impurities are intercepted on the surface of the filter plate 6 to prevent them from entering the drainage pipe body 5 and causing blockage. When a lot of impurities accumulate on the surface of the filter plate 6, the motor 9 starts, driving the first threaded rod 10 to rotate, causing the moving plate 11 to move along the threaded rod, pushing the filter plate 6 to slide within the fixed frame 3, scraping the blockage off to the collection frame 7, and completing the automatic cleaning.

[0026] In this utility model, preferably, a drain door 12 is symmetrically fixedly connected to one side of the top of the drain tank 1, and a mounting block 13 is symmetrically fixedly connected to one side of the top of the drain door 12. A fixing buckle 14 is rotatably connected between the two sides inside the mounting block 13. The drain door 12 is designed to be openable and closable through the mounting block 13 and the fixing buckle 14 at the top, which facilitates manual inspection or cleaning of the internal components.

[0027] In this utility model, preferably, a water outlet pipe 15 is fixedly connected to the bottom of one side of the drain tank 1, and support feet 16 are fixedly connected to the four corners of one side of the bottom of the drain tank 1. A pressure sensor 18 is fixedly connected inside the drain pipe body 5. The pressure sensor 18 monitors the water pressure inside the drain pipe body 5 in real time. If the pressure rises abnormally, it needs to be cleaned.

[0028] In this utility model, preferably, a first sliding rod 17 is fixedly connected between the two sides inside a groove 8, and the other end of a movable plate 11 is slidably connected to the outside of the first sliding rod 17. The first sliding rod 17 serves to limit the movement of the movable plate 11.

The other end of the fixing buckle 14 is movably connected to one side of a drain gate 12.

[0029] The working principle and usage process of this utility model are as follows: During use, the circulating water of the cooling tower enters the drain tank 1 through the inlet 2. The water flow first passes through the filter plate 6, and impurities are intercepted on the surface of the filter plate 6 to prevent them from entering the drain pipe body 5 and causing blockage. Multiple circular grooves 4 and corresponding filter plates 6 can simultaneously handle large flow rates of water, improve filtration efficiency, and avoid single-path blockage affecting overall drainage. When a lot of impurities accumulate on the surface of the filter plate 6, the motor 9 starts, driving the first threaded rod 10 to rotate, causing the moving plate 11 to move along the threaded rod, pushing the filter plate 6 to slide within the fixed frame 3, scraping the blockages off into the collection frame 7, completing automatic cleaning. The pressure sensor 18 monitors the water pressure inside the drain pipe body 5 in real time. If the pressure rises abnormally, cleaning is required.
