Problems solved by technology
[0004] In the process of water quality testing, it is generally necessary for the testing personnel to take samples through the sampling device and then use the instrument for testing, but the existing sampling devices have the following disadvantages: 1. Manual extraction is required by the testing personnel, and the samples need to be discharged into the water storage bottle after extraction storage in the middle, complex operation, poor practicability, 2, the extraction position of the existing sampling device is not easy to control

The present invention relates to the technical field related to water resource detection, in particular to a sampling structure and water resource utilization detection equipment. The sampling structure includes a sleeve and a handle fixed at one end of the sleeve. The sleeve is far away from the handle. One end is provided with a sampling head assembly, and the sampling head assembly is connected to a telescopic assembly arranged in the sleeve, and the telescopic assembly can be used to adjust the position of the sampling head assembly; the sampling head assembly includes a The sampling head connected to the rod assembly and the sampling tube fixed at the end of the sampling head away from the connecting rod assembly, a suction assembly is also provided inside the sampling head, and the suction assembly is used to extract samples. Control the movement of the drive assembly through the set control device, thereby driving the movement of the connecting rod assembly, so that the sampling head can meet different sampling requirements in different states of the connecting rod assembly, with strong practicability, and the required sampling can be achieved at the sampling head through the set suction assembly Sampling is implemented after the position.
Description
technical field [0001] The invention relates to the related technical field of water resource detection, in particular to a sampling structure and water resource utilization detection equipment. Background technique [0002] Water is the source of life, scientific and reasonable protection of water resources requires investment in advanced technology and equipment. [0003] Water resources monitoring is used by the water affairs department to monitor water intake from self-provided wells, monitor water flow in and out of water plants, monitor open channel flow, monitor groundwater levels, monitor water quality in water sources, and conduct remote water sales management of water resources, etc. It has played an important role in effectively protecting water resources, rationally utilizing water resources, and strengthening social awareness of water conservation. [0004] In the process of water quality testing, it is generally necessary for the testing personnel to take samp...
