AI Technical Summary
During long-term use, existing submersible pumps are prone to rust due to the lack of protection at the connection between the pump body interface and the water pipe, and the bottom sand and sludge enter the pump, resulting in a decrease in the rate of water delivery, and the maintenance personnel cannot be reminded in time to check.
A submersible pump is designed, adopting the rapid disassembly design of the first protective plate and the second protective plate. Through the coordination of the limit rod and the spring, the water outlet is avoided from being connected to the water pipe for a long time and preventing rust. At the same time, the flow rate sensor is located at the center of the inner wall of the water inlet, and is used to detect the flow rate of the water source. When the rate is slow, the maintenance personnel are reminded to check whether there are any sand and mud and other debris blocked.
It effectively prevents rust from the pump body interface, extends the service life of the equipment, and uses real-time monitoring of the flow rate sensor to timely detect and deal with debris in the pump, ensuring the stability and efficiency of water source transportation.

[0010] As a preferred technical solution of the utility model, the output end of the controller is electrically connected to the flow rate sensor and the input end of the solenoid valve respectively, and the flow rate sensor is located at the center of the inner wall of the water inlet.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The submersible pump utilizes external force to pull the limit rod, and the limit rod drives the circular plate to compress the spring, so that the limit rod is separated from the inner wall of the second protective plate, thereby allowing the first protective plate and the second protective plate to be quickly disassembled. When the first protective plate and the second protective plate are fitted together, the limit rod releases the pressure through the elastic force of the spring, and the limit rod penetrates into the inner wall of the second protective plate for quick installation, thereby preventing the water outlet from being connected to the water pipe for a long time, causing the water outlet to rust, the water pipe mouth to rupture, and reducing the service life of the equipment.

When the pump body delivers water, the flow rate sensor is used to test the water flow rate of the inner wall of the pump body. When the rate is slow, the flow rate sensor blocks the debris at the water inlet, thereby reminding the maintenance personnel to check whether the water inlet is blocked by sand, mud and other debris.

In the above structure, the other end of the spring 11 is fixed to the inner wall of the first protective plate 5, and the limiting rod 9 is pulled by external force. The limiting rod 9 drives the circular plate 10 to compress the spring 11, so that the limiting rod 9 is detached from the inner wall of the second protective plate 12, thereby allowing the first protective plate 5 and the second protective plate 12 to be quickly disassembled.
