Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to an environmental monitoring polluted water sampling device. Background Art

[0002] Water pollution is caused by harmful chemicals that reduce or lose the use value of water and pollute the environment. Acids, alkalis, oxidants, compounds such as copper, cadmium, mercury, arsenic, and organic toxins such as benzene, ethylene dichloride, and ethylene glycol in sewage can poison aquatic organisms and affect drinking water sources and scenic spots. When organic matter in sewage is decomposed by microorganisms, it consumes oxygen in the water, affecting the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobically decomposition, producing unpleasant gases such as hydrogen sulfide and mercaptans, which further deteriorate the water quality. Patent application number CN202020399090.7 is a contaminated water sampling device, and its content is: The utility model discloses a contaminated water sampling device, which includes a liquid guide tube with a closed lower end, a mounting plate fixed to the upper end of the liquid guide tube, and a portable rod fixed to the top of the mounting plate, the lower end of the liquid guide tube is fixed and connected with multiple transverse tubes along the circumferential direction, and the other end of the transverse tube is fixed and connected with a vertical outer sleeve, the inner side of the outer sleeve is movably plugged with an inner sleeve, and the lower end of the outer sleeve is threadedly connected with a locking screw with one end pressed on the inner sleeve, the lower side of the transverse tube is fixed and connected with a vertical liquid outlet pipe, the lower end of the liquid outlet pipe is threadedly sleeved with a liquid collecting bottle, and a valve is installed on the liquid outlet pipe, and a driving motor is fixed on the mounting plate. The utility model can not only extract multiple bottles of water samples at one time, but also extract water samples of different depths at one time, with high sampling efficiency and good flexibility of use, simple structure of the whole device, low manufacturing cost, and easy to carry.

[0053] The water is transferred to the interior of the flow guide tube 33, and then passes through the flow guide tube 33 and the area of ​​the built-in access rubber tube 48 to the suction tube seat 47 and the branch pipe joint 46;

[0054] The output end of the shunt pump motor 42 rotates when it is powered on, driving the impeller to rotate, generating attraction from the water inlet to the position of the shunt joint 46, and then the water is shunted through the receiving hose 44 and transported to two independent sample storage tanks 591 to complete the water sample collection by standing beside the river or at a high-rise small bridge. Moreover, various pipe fittings are set up once and can be disassembled to ensure that when extracting different rivers, the influence of sample variables is considered and the variables are limited.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
