Further, the upper baffle is made of plastic, and the water sampling bottle and the lower baffle are made of plexiglass.

Further, the support of the water collector includes an upper panel and a lower panel, both of which are made of iron, which play a role in weighting, and several connecting rods connecting the upper panel and the lower panel; the lower side of the middle part of the upper panel is provided with an upper step The upper side of the middle part of the lower panel is provided with a lower step hole, the top wall of the water collection bottle is against the step surface of the upper step hole, the bottom wall of the water collection bottle is against the step surface of the lower step hole, and the outer side wall of the water collection bottle It fits the hole walls of the upper and lower step holes; the rod of the upper guide bolt connects the upper panel and the top wall of the water collection bottle.

Further, the retractable device is composed of a main rope, a branch rope and more than three eyebolts, the eyebolts are evenly arranged on the peripheral side of the upper panel of the water collector support, branch ropes are connected to the eyebolts, and the upper ends of the branch ropes Converge at the lower end of the main rope.

The beneficial effects of the utility model compared with the prior art are:

The inner side of the bottom wall of the water collection bottle of the utility model is vertically provided with a lower guide bolt, and the lower guide bolt is movable and fitted with a lower baffle plate which can cover the lower water inlet. The outer side of the top wall of the water collection bottle is vertically provided with an upper Guide bolts, the upper guide bolts are set with an upper baffle plate that can cover the upper water outlet, the design of the guide bolts is compared with the design of the traditional inner wall forming retaining ring in the middle of the water collection bottle (the design of the retaining ring is to prevent the water collection bottle The piston at the water inlet of the water bottle is turned over, and the piston is replaced by the lower baffle in this device), and its processing is simple, which can ensure the sealing effect after the device collects water. At the same time, the middle part of the lower side of the lower baffle is provided with grooves The design of the groove makes the lower baffle easier to be lifted up by the water flow when the device sinks;

When the utility model sinks, the lower baffle will be directly lifted up, and only after a certain amount of water enters the water collection bottle and the air pressure in the water collection bottle is greater than the water body pressure on the upper side of the upper baffle, the upper baffle will be lifted. Therefore, designing the upper baffle and the water collection bottle with different materials can make it easier for the water to flow into the water collection bottle; when the device completes the collection of water, the water in the water collection bottle will leave the collection bottle from the lower water inlet. The trend of water bottles, and the water collection bottle and the lower baffle are made of the same material of plexiglass, so it can be well sealed when under pressure, preventing the water in the water collection bottle from flowing out of the lower water inlet. This design makes the sampling of the device more efficient. Accurate and stable.
