Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a sampling device for water quality testing. Background Technology

[0002] Water quality testing requires the initial extraction of water samples. Existing sampling devices cannot accurately measure or control the sampling depth, hindering subsequent analysis and processing. Furthermore, existing devices lack cleaning capabilities; since some water samples contain significant amounts of sludge, some sludge adheres to the sampling tube during sampling, affecting subsequent use. Therefore, there is an urgent need to develop a water quality testing sampling device that is easy to operate, allows for accurate control of the sampling depth, and facilitates the cleaning of accumulated sludge from the sampling tube, overcoming the shortcomings of current applications and meeting current needs. Utility Model Content

[0003] The purpose of this invention is to provide a sampling device for water quality testing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sampling device for water quality testing includes a base, a display screen, control buttons, a power supply, a lifting plate, a telescopic rope, a first wire, a second wire, a winding wheel, a sampling cylinder, a water inlet pipe, a solenoid valve, a cleaning mechanism, and a water depth sensor. A winding wheel is fixed to the bottom of the base, and a telescopic rope is wound around the winding wheel. The bottom of the telescopic rope is fixed to the lifting plate. A water depth sensor and a sampling cylinder are installed on the lower side of the lifting plate. A water inlet pipe is installed on the sampling cylinder, and a solenoid valve is installed on the water inlet pipe. A display screen and control buttons are installed on the base. A cleaning mechanism is detachably installed on the sampling cylinder. The cleaning mechanism includes a bottom cover, a rotating shaft, a scraper, and an operating rod. The bottom cover is detachably fixed to the bottom of the sampling cylinder via threads. A rotating shaft is rotatably connected to the bottom cover. A scraper is fixed to one side of the rotating shaft, and the scraper is in contact with the inner wall of the sampling cylinder. An operating rod is fixed to the bottom of the rotating shaft.

[0006] Preferably, a handle is fixed on the base, and both the base and the handle are made of aluminum alloy.

[0007] Preferably, a mobile power supply is installed on the base.

[0008] Preferably, the water depth sensor is electrically connected to the display screen via a first wire, and the solenoid valve is electrically connected to the control button via a second wire.

[0009] Preferably, both the first and second conductors are connected to the telescopic rope via waterproof tape.

[0010] The beneficial effects of this utility model are as follows: When using this sampling device for water quality testing, the lifting plate is placed in the water, and the water depth is detected by a water depth sensor and displayed on a screen. Then, the operator can adjust the depth of the lifting plate by extending or retracting the telescopic rope on the winding wheel as needed. Once the desired depth is reached, the solenoid valve is opened via a control button, allowing water to flow into the sampling cylinder through the inlet pipe. The solenoid valve is then closed, and the lifting plate is removed from the water, ensuring accurate control of the sampling depth. After use, the operator manually rotates the operating lever to rotate the shaft and scraper, which cleans away the sludge accumulated on the inner wall of the sampling cylinder. The fallen sludge is collected by the bottom cover, and finally, the bottom cover is removed to empty the sludge. In summary, this utility model is easy to operate, facilitates accurate control of the sampling depth, and makes cleaning the sludge accumulated in the sampling cylinder convenient.
