However, picking up the water pipe after each use and putting it back when using it can effectively solve the above problem, but this method will result in time-consuming and labor-intensive. Summary of the invention

[0004] The purpose of the present invention is to provide a water quality detection device for monitoring aquatic biological resources.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0018] A water quality detection device for monitoring aquatic biological resources, comprising a pipeline 2 connected to a detection pool 1, wherein a water pump 13 is arranged on the pipeline 2, and a water pump 4 is also arranged at the end of the pipeline 2, and the water pump 4 is arranged on a floating plate 5:

[0019] The floating plate 5 is provided with a sleeve 6 for the insertion rod 7 to pass through, wherein the floating plate 5 is also provided with a plastic cylinder 8, wherein the upper opening of the cylinder 8 is provided with a mounting plate 9 for fixing the upper and lower ends of the water pump 4, wherein a liquid storage chamber 10 is constructed in the cylinder 8 between the two sets of mounting plates 9, wherein the liquid storage chamber 10 is provided with a water inlet hose 11 and a water outlet hose 12 connected to the water pump II13, wherein the water inlet hose 11 and the water outlet hose 12 are respectively connected to the three-way pipe I14 and the three-way pipe II15 on the inlet and outlet ends of the water pump II13, and a drainage pipe 16 and a connecting pipe 17 connected to the water source are respectively provided on one end of the three-way pipe I14 and the three-way pipe II15, and solenoid valves are provided at the inlet and outlet of the three-way pipe I14 and the three-way pipe II15;

[0020] A filter cartridge I18 connected to the lower mounting plate 9 is suspended at the bottom of the cylinder 8, wherein the filter cartridge I18 is jacketed on the bottom end of the water suction pipe 4, and a conical seat 19 is provided at the bottom of the filter cartridge I18, wherein the filter cartridge I18 and the conical seat 19 are also jacketed with a filter cartridge II20 with a bottom sealing arrangement.

[0021] In this embodiment, the inner diameter of the sleeve 6 is greater than the diameter of the insertion rod 7 , wherein the sleeve 6 is fixedly connected to the floating plate 5 .

[0022] like Figure 1 , 2 As shown, the bottom end of the filter cartridge II20 is not lower than the horizontal plane of the bottom end of the floating plate 5, wherein the pore size of the side wall of the filter cartridge II20 is larger than the pore size of the side wall of the filter cartridge I18, and the top end of the filter cartridge I18 and the filter cartridge II20 are fixedly connected to the lower mounting plate 9, wherein the side wall of the bottom sealing end of the filter cartridge II20 is a mesh structure, and a spiral tube threadedly connected to the inner top wall of the filter cartridge II20 is also provided at the bottom of the lower mounting plate 9.

[0023] When the float 5 is placed on the water surface and is affected by the buoyancy, it suspends the cylinder 8 and components such as the filter cartridge I18 and the filter cartridge II20 and makes them float on the water surface, preventing the above components from being immersed in water for a long time and breeding moss, etc., which would affect their subsequent normal use.

[0024] like Figure 1 , 2 As shown, the side wall of the cylinder 8 above the lower mounting plate 9 is tilted outwards and is provided with an expansion portion. The capacity of the liquid storage chamber 10 is expanded by the expansion portion.

[0025] like Figure 1 , 2 As shown, the rod 7 is inserted into the ground of a lake or river, and the floating plate 5 can slide up and down on the rod 7 through the sleeve 6, so that the floating plate 5 floats on the water surface. At this time, the rod 7 plays a positioning role for the floating plate 5 to prevent it from floating and displacing due to the influence of water surface fluctuations;

[0026] The lower floating plate 5 floats on the water surface under the influence of buoyancy, so that the filter cartridge I18, filter cartridge II20 and water pumping pipe 4 and other components are suspended above the water surface, so that the above components do not need to be taken off the water surface when not in use, and the above components will not breed moss due to long-term immersion in water, thereby effectively ensuring the safety of subsequent use;

[0027] When it is necessary to extract and test the liquid in the water, open the solenoid valve at the connection between the three-way pipe I14 and the water inlet hose 11, and the solenoid valve at the connection between the three-way pipe II15 and the connecting pipe 17, and the other solenoid valves are in the closed state. Then the water pump II13 works to pump the liquid in the water source through the connecting pipe 17 and the three-way pipe II15 into the liquid storage chamber 10 through the three-way pipe I14 and the water inlet hose 11 to fill it. Under the pressure of the gravity of the liquid in the liquid storage chamber 10, the float 5 sinks into the water, and then drives the filter cartridge I18, the filter cartridge II20 and the water pumping pipe 4 to slide into the water. Then the water pump I3 works to pump the liquid into the detection tank 1 through the pipeline 2 and the water pumping pipe 4 for detection. In the above process, the filter cartridge I18 and the filter cartridge II20 can filter the impurities and aquatic organisms in the liquid to prevent them from entering the detection tank 1 and affecting the detection work;

[0028] When the extraction is completed, the solenoid valve at the connection between the three-way pipe I14 and the water outlet hose 12 and the solenoid valve at the connection between the three-way pipe II15 and the drain pipe 16 are opened, and the other solenoid valves are in a closed state. Then the water pump II13 works to return the liquid in the liquid storage chamber 10 to the water source through the water outlet hose 12 and the drain pipe 16. Then, after the liquid in the liquid storage chamber 10 is drained and loses its gravity squeeze, the floating plate 5 will drive the sleeve 6 to slide upward on the plug rod 7, and then float on the water surface, so as to suspend the filter cartridge I18, filter cartridge II20 and the water pumping pipe 4 and other components above the water surface. It should be noted here that the reason why the water pump II13 is not used through the connecting pipe 17 and The water inlet hose 11 directly draws liquid into the detection tank 1 for detection, because it does not have a filtering mechanism to filter the extracted liquid, which will cause impurities to enter the detection tank 1 and affect the detection work. If a filtering mechanism is set at its inlet end, the situation described in the technical background will also occur. At the same time, when the connecting tube 17 is used to directly draw liquid into the detection tank 1, it also needs to be taken out of the water after use and put back in when used. Otherwise, moss will grow due to long-term immersion in liquid. In this embodiment, the liquid containing impurities is pumped into the liquid storage chamber 10 through the connecting tube 17 via the water pump II13 for counterweighting, which will not affect the detection work.

[0029] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
