[0002] The circulating water pump unit in a power plant is one of the important auxiliary equipment in the power plant. It is mainly used to transport and circulate cooling water to maintain the normal operation of the equipment and improve thermal efficiency. When the circulating water pump unit in a power plant is running, a monitoring device is needed to track the operating status of the pump, so as to discover and solve potential efficiency problems, thereby ensuring that the pump operates under optimal working conditions.

[0003] For example, an energy-saving monitoring device for a circulating water pump unit in a thermal power plant with publication number CN216665897U includes a base plate, the top of the base plate is fixedly connected to a frame and is arranged horizontally, a water pump is installed inside the frame and is arranged horizontally, one side of the water pump is fixedly connected to a connecting pipe and is arranged horizontally, the end of the connecting pipe away from the water pump is fixedly connected to a first water inlet pipe and is arranged vertically, the top of the first water inlet pipe is threadedly connected to a second water inlet pipe and is arranged vertically, a threaded screw is provided inside the second water inlet pipe and is arranged vertically, the outer side of the threaded screw is threadedly connected to a threaded connecting long pipe and is arranged vertically, the outer side of the threaded connecting long pipe is fixedly connected to a number of equally spaced hollow connecting blocks and are arranged vertically, a slot is provided inside the hollow connecting block, and impurities and garbage in the water flow are filtered through a filter net to prevent impurities and garbage from entering the first water inlet pipe and causing blockage, thereby affecting subsequent work.

[0004] The above patent proposes that impurities and garbage in the water flow can be filtered to ensure smooth water flow and allow the water pump unit to operate normally.

[0024] The mounting structure 4 includes an annular frame 41 and a bracket 47 arranged at the front end of the annular frame 41. The bracket 47 is provided with screws, which can fix the bracket 47 on the pipe 3, so that the annular frame 41 is placed at the connection between the pump body 2 and the pipe 3. A fixing frame 42 is provided on one side of the annular frame 41. A motor 43 is provided on the fixing frame 42.
