Problems solved by technology

[0002] At this stage, water collection devices are widely used in the collection of water samples from rivers and lakes, but the current water collection devices on the market are mainly for single sampling, and they need to be lowered multiple times when used for multi-depth water collection operations, resulting in the efficiency of water sample collection. and low precision
The current patent with the publication number of CN 111473999A discloses "A Water Quality Sampling Device Based on Multi-rotor UAV", which realizes the sampling of water samples in lakes by installing a vertical water sampling device under the UAV. Automatic collection does not require staff to collect water samples by boat, which effectively reduces the labor intensity of staff and brings convenience to lake water sample collection; but it has some shortcomings in practical application, such as: it cannot Collect water samples at different depths internally. After one collection, you need to return to the voyage, and the collection efficiency is relatively low.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0013] A water collection device for multi-depth water sample collection, which consists of an antenna 1, a connecting seat 2, a bearing 3, a pressure plate 4, a set screw 5, a shaft coupling 6, a waterproof motor 7, a piston 8, and a collection bottle 9 , collection bottle fixed frame 10, support base 11, chassis 12, spring 13, blocking strip 14 and water blocking sheet 15 constitute.

[0014] The water sample collection device is connected to the bank, the ship or the turntable of the drone through a rope, and the device is lowered to different depths through the rotation of the turntable.

[0015] The staff sends a signal, and the waterproof motor 7 starts to rotate, and drives the pressure plate 4 to turn over a specified angle, and the breach of the pressur...

Abstract

The invention discloses a water sampling device for multi-depth water sample collection. The water sampling device comprises an antenna, a connecting seat, a bearing, a pressure plate, a set screw, a coupler, a waterproof motor, a piston, a collecting bottle, a collecting bottle fixing frame, a supporting seat, a chassis, a spring, a blocking strip and a water blocking sheet. The upper end of the connecting seat is provided with the antenna, and the lower end is provided with the chassis. An outer ring of the bearing is connected with a circular ring above the connecting seat, and an inner ring of the bearing is connected with an upper side shaft of the pressure plate. One end of the coupler is fixed with a lower side shaft of the pressure plate through a set screw, and the other end is fixed with a motor shaft. The supporting seat is fixed on the chassis, the waterproof motor is mounted in the supporting seat, and the collecting bottle fixing frame is mounted on the outer side of the supporting seat. When the pressure plate rotates by a specified angle, the piston is positioned at a notch and is not blocked by the pressure plate, and the spring pushes the piston to move upwards, so that negative pressure is generated in the collecting bottle, and a water sample is sucked into the bottle. According to the water sampling device, water samples at multiple depths can be respectively collected in single water sampling operation, and the water sampling efficiency is improved.
