[0002] The circulating water system of a thermal power plant circulates water through equipment such as cooling towers and condensers to cool the exhaust steam from the steam turbine and other equipment. The system flow is as follows: cooling tower → circulating water pump room → condenser → cooling tower, forming a closed loop. Piping types: the main circulating water pipes mostly use large-diameter welded steel pipes, such as DN2400 prestressed concrete cylinder pipe (PCCP) or D2020x12 welded steel pipes; branch pipes use specifications such as D1620x12.

[0003] Currently, circulating water pipelines in thermal power plants are prone to blockages during use, requiring manual unblocking. Manual unblocking is time-consuming and labor-intensive, cannot quickly remove sludge, has poor functionality, and low unblocking efficiency.

[0004] Therefore, it is necessary to design and modify the sludge dredging equipment to effectively prevent the current circulating water pipelines of thermal power plants from frequently becoming clogged during use. In use, manual dredging is required, which is time-consuming and labor-intensive, cannot quickly remove sludge, has poor functionality, and low dredging efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an automated mechanical device for dredging circulating water pipelines in thermal power plants. This device has the advantage of efficient pipeline dredging and solves the problem that circulating water pipelines in thermal power plants are prone to blockage during use. In current use, manual dredging is required, which is time-consuming and labor-intensive, cannot quickly remove sludge, has poor functionality, and low dredging efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated mechanical device for dredging circulating water pipelines in thermal power plants, comprising an automatic dredging equipment body, a metal pipe fixedly connected inside the automatic dredging equipment body, a nozzle connected to the top of the metal pipe, a fixed frame fixedly connected to the top of the automatic dredging equipment body, a transmission component provided at the bottom of the fixed frame, a rotating rod movably connected to the top of the fixed frame, a dredging component provided at the top of the rotating rod, and a water pipe connected to the bottom of the inlet pipe.

The waterproof motor drives the first gear to rotate, which in turn drives the second gear to rotate, which in turn drives the rotating rod to rotate. The rotating rod then drives the fixed disc to rotate, which in turn drives the crushing teeth to rotate. This process effectively clears sludge from the pipe. Simultaneously, water is transmitted through the pipe to the metal pipe and then sprayed out through the nozzle. This method replaces the existing manual sludge removal method, achieving rapid sludge removal with a high level of safety.

[0015] 2. This utility model achieves effective transmission of the rotating rod through the setting of the transmission component. This design ensures that the rotating rod can drive the fixed disk to rotate stably, thereby enabling the fixed disk to drive the crushing teeth to efficiently clean the sludge in the pipe.

This design ensures that the dredging effect of the pipe is significant, and the silt can be discharged quickly, which greatly improves the smoothness of the pipe. This dredging mechanism not only improves the efficiency of dredging, but also provides great convenience for users, making pipe maintenance simpler and faster.

[0017] 4. By setting a limit frame, this utility model can accurately limit the top of the first gear. This design ensures the stability of the first gear during operation, thereby ensuring the stable operation of the entire transmission system. The setting of the limit frame not only improves the reliability of the equipment, but also provides users with a safer and more convenient operating environment.

[0018] 5. By setting up a protective cover, this utility model can effectively protect the outer sides of the first gear and the second gear. This design ensures stable meshing between the gears and prevents the adverse effects of silt on the meshing process. The use of the protective cover not only improves the protection effect of the gears, but also ensures the stability and durability of the equipment in harsh working environments.

[0019] 6. By setting the number of crushing teeth to several, this utility model can fully impact and crush the sludge. This design ensures that the sludge can be quickly and effectively dredged and discharged, significantly improving the discharge efficiency. The reasonable configuration of the crushing teeth not only speeds up the cleaning process but also improves the efficiency and effectiveness of the entire cleaning process.

[0020] 7. This utility model provides all-round protection for the outer side of the automatic sludge removal equipment body through the setting of the protective ring. This design effectively avoids collisions and damage to the automatic sludge removal equipment body during use, improves the safety of the equipment, and the use of the protective ring not only protects the equipment from external damage, but also provides users with a safer and more reliable operating experience.
