Title:
WATER QUALITY SAMPLING DEVICE FOR ENVIRONMENTAL PROTECTION TECHNOLOGY DEVELOPMENT
Document Type and Number:
WIPO Patent Application WO/2021/174449
Kind Code:
A1
Abstract:
A water quality sampling device for environmental protection technology development, comprising a floating main board (1). A bottom plate (2) is fixedly provided on the bottom surface of the floating main board (1), a lifting and lowering base (21) is provided on the bottom of the bottom plate (2); mounting plates (3) are provided on both the front and rear surfaces of the floating main board (1); a drive box (4) is provided on the outer surface of each mounting plate (3); a control device (5) is provided on the top surface of the floating main board (1); the top of the control device (5) is connected to a signal receiver (6) by means of a transmission cable; and top plates (7) are provided on two sides of the control device (5). In the water quality sampling device, the lifting and lowering base (21), detection plates (8), and sampling tubes (9) are provided; hydraulic lifting and lowering rods (22) push the lifting and lowering base (21) to move downward; during the movement, ultrasonic distance measuring sensors (23) measure the depth of the detection plates (8) to determine the depth of sampled water; after reaching a specified depth, miniature water pumps (91) operate and suck water into the sampling tubes (9); the water would not flow out after entering the sampling tubes (9) from check valves (92), and the multiple sampling tubes (9) can work separately, thereby achieving the sampling of water quality at different depths and different positions and improving the work efficiency.
