AI Technical Summary
Existing prefabricated pumping stations cannot effectively collect floating debris with a density lower than that of clean water, leading to pump malfunctions. Furthermore, existing automatic collection devices are complex in structure and have high maintenance costs.
Design an automatic collection device for floating debris on the surface of a pumping station. The device uses a float and the negative pressure of the water pump to drive the float plate to open and close the water inlet. Combined with a lightweight design and a PLC controller, it can automatically collect floating debris and prevent leakage. The device can be lifted to the maintenance platform for cleaning.
It achieves effective automatic collection of floating objects, reduces failure rate and maintenance cost, has a simple structure, and is reliable in operation. The design of the device, through the self-adaptability of the float, solves the problem of liquid level regulation of the floating device, realizes the design of the automatic collection device for floating objects, solves the problems of automatic collection of floating objects and prevention of leakage, and achieves effective automatic collection of floating objects, reducing failure rate and maintenance cost.
