Water sampling device for multi-depth water sample collection

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.

Description

technical field [0001] The invention relates to the technical field of water sample collection, in particular to a water collection device for multi-depth water sample collection. Background technique [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 convenienc...

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.
