Description

Technical Field

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

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating water quality conditions. In the field of water environment monitoring, in order to obtain true, accurate and complete water quality monitoring data, it is first necessary to use a sampling device to collect water quality samples for monitoring water bodies.

[0003] In the prior art, there is a sampling device for water quality monitoring with announcement number CN220084391U, which includes: a float and a control system; two sets of drive components are arranged at the rear end of the float, and the drive components are used to drive the float to move on the water surface; the upper surface of the float is connected with a retractable component, and the lifting end of the retractable component is connected with a sampling bottle; when working, the float is placed in the detection water area, and the control system controls the drive component to drive the float to move, and the float is moved to the detection point, and then the sampling bottle is driven to fall by the retractable component until it falls to the specified sampling depth. After sampling with the sampling bottle, the sampling bottle is lifted up by the retractable component, and then the float is brought back to the shore by the drive component, and the sampling bottle is removed to complete the remote sampling.

[0004] However, in the above scheme, the sampling bottle arranged under the retractable assembly can only collect one water quality sample at a time. When the sampling device collects multiple water quality samples in the same water area, the sampling device has to return to the shore to replace the sampling bottle each time it collects one water quality sample. This process is relatively cumbersome and inconvenient for collecting multiple water quality samples. Utility Model Content

[0005] The utility model aims to provide a water quality detection sampling device, which can be convenient for collecting a variety of water quality samples.

[0007] The working principle and effect of the above scheme are as follows: the floating seat and the floating ball are both hollow structures, and the buoyancy generated by the floating seat and the floating ball can make the sampling device float on the water surface, the driving component can drive the sampling device to move, and the retracting component can adjust the length of one end of the water inlet pipe extending out of the floating seat; when working, the sampling device is placed on the detection water area, the driving component is started, the driving component drives the sampling device to the detection point, the retracting component is started, so that one end of the water inlet pipe is located within the depth range of the water body to be detected, and all reversing valves are closed. At this time, the water distribution pipe and the water outlet pipe are not connected, and the water pump is started. Water flows from the water inlet pipe through the water pump to the water outlet pipe and flows out at the other end of the water outlet pipe. When the water in the water inlet pipe and the water outlet pipe is the water of the water area to be detected, one of the reversing valves is opened. At this time, the water outlet pipe is not connected here, and the water outlet pipe is connected to the corresponding water distribution pipe.
