[0002] Environmental protection generally refers to the general term for various actions taken by humans to solve real or potential environmental problems, coordinate the relationship between humans and the environment, protect the living environment of humans, and ensure the sustainable development of the economy and society. In environmental protection operations, the detection of water bodies is also crucial. When carrying out environmental protection work in a certain water body, it is necessary to use a water sampling device to regularly collect water samples from the water body and send them to the laboratory for component testing to ensure that the water in the water body is uncontaminated.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in the technology: most of the water sample collection devices currently used in environmental protection detection work can only collect water samples from a specified depth in the water area at one time. If water samples at multiple different depths need to be collected, multiple collections can only be performed, resulting in low collection efficiency.

[0004] To this end, we propose a water sample collection device for environmental protection testing to solve the above problems. Utility Model Content

[0008] A plurality of water inlets evenly spaced in the vertical direction are provided on one side wall of the collecting tube, top grooves are formed upwardly inside the collecting tube where the multiple water inlets are located, storage chambers corresponding to the multiple top grooves are formed inside the collecting tube, servo motors are horizontally installed in the multiple storage chambers, and inner shafts are coaxially connected to the ends of the output shafts of the multiple servo motors, side sealing doors for closing the multiple water inlets are fixedly mounted on the multiple inner shafts, and the lifting motor and the servo motor both require power supply from external power facilities.

[0009] As a preferred embodiment, a through hole is formed on the support plate and passes through the top wall and the bottom wall thereof, wherein the cable passes through the through hole and extends toward the bottom of the support plate; thereby facilitating the smooth lowering of the cable from the support plate.

[0010] As a preferred embodiment, both ends of the storage cylinder are rotatably connected to two lifting motors respectively, so that the storage cylinder can operate stably and the cable on the storage cylinder can be released or retracted.

[0011] As a preferred embodiment, track plates are symmetrically welded on both sides of the bottom wall of the support plate, and the two opposite side walls of the collection tube are respectively fitted with the two track plates; so that the collection tube can be raised and lowered with the two track plates, so that the raising and lowering of the collection tube remains stable.

[0012] As a preferred embodiment, the inner shaft is horizontally arranged and rotatably connected to the collecting barrel, so that the inner shaft can operate stably.

[0013] In summary, the technical effects and advantages of the utility model are as follows:

[0014] The water sample collection device for environmental protection detection drives the lifting motor to lower the cable, so that the collection tube sinks to a specified depth in the water along the track plate, and then drives multiple servo motors to open multiple water inlets, so that water samples at different depths can enter different water inlets respectively, and multiple side sealing doors can close the multiple water inlets, so that water samples at different depths can be collected at one time, thereby improving the water sample collection efficiency.
