Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, and more specifically to a water quality sampling device. Background Art

[0002] In the sampling device for water quality detection with the publication number CN218766187U, it is proposed that the pollutants contained in the water environment at different depths are different, and it is necessary to sample the water bodies at different depths. By moving the closing device to open the sampling holes, the sampling work is started, which improves the sampling accuracy. And by arranging two circles of sealing rings on both the inner and outer sides of a circle of sampling holes, the sealing effect is achieved. After the sampling device reaches a certain depth, the closing device can drive the lead screw to rotate through a servo motor, so that the bottom cover moves away from the sampling tank, thereby opening all the sampling holes. Then, the valve and the water pump are opened, so that water quickly enters the sampling tank through the sampling holes. Then, by closing the closing device, the valve and the water pump, the sampling is completed.

[0003] The above patent can sample at a certain depth. However, in the actual use process, when it is necessary to sample at different depths, the above device can only sample at one depth each time. When sampling multiple times, it is necessary to take the device out of the water and place it in the water back and forth many times, which is rather inconvenient. Therefore, we propose a water quality sampling device. Summary of the Utility Model

A pushing block is fixedly connected to the side of the operation bar close to the rectangular frame. And a through hole communicating with the inside of the clamping groove is opened on the side surface of the rectangular frame.

[0007] Furthermore, an adjusting mechanism is installed above the loop-shaped frame. The adjusting mechanism includes a sleeve.
