Description

Technical Field

[0001] The utility model relates to the technical field of water environment restoration, in particular to a water sampler for restoration. Background Art

[0002] Water environment restoration refers to reducing or eliminating pollutants in water bodies by taking appropriate measures and technologies. Common water environment restoration methods include physical treatment, chemical treatment, and biological treatment to protect water quality and maintain the health of the ecological environment.

[0003] For water environment testing, common methods include water sampling and laboratory analysis. Water sampling can obtain information about water quality by collecting water samples from different locations and times. Laboratory analysis can detect substances in water samples that affect water quality, such as heavy metals, organic matter, bacteria, and nutrients. Based on the test results, the degree of pollution of the water environment and the source of pollutants can be evaluated, so as to formulate corresponding governance and remediation strategies. The water samples for testing are mainly collected through water samplers.

[0004] Existing water samplers mainly use ropes to lower the sampling tube into the water body for sampling. However, in waters with turbulent water flow, when sampling at deep depths, the rope is hung too long and the water flow can easily impact the sampling tube and the rope into an inclined state, which will cause the depth of the sampling tube to change and affect the accuracy of sampling.

[0030] Furthermore, a water inlet is provided at the upper portion of the sampling tube 4; a sealing mechanism is provided at the top of the sampling tube 4, and the sealing mechanism includes a sealing plug 52 for opening or sealing the water inlet; the sealing mechanism also includes a bracket provided at the top of the sampling tube 4, and the bracket is provided with a guide hole 501, and a guide rod 51 is passed through the guide hole 501, and both ends of the guide rod 51 are respectively connected to the traction rope 6 and the sealing plug 52, and a spring 53 is sleeved on the guide rod 51, and both ends of the spring 53 respectively support the bracket and the sealing plug 52.

[0031] In the utility model, the elastic force of the spring 53 is used to push the sealing plug 52 into the water inlet 401 for sealing. When not sampling, it can prevent water from other places from entering the sampling tube 4 and contaminating the sample, thereby ensuring higher sampling accuracy. When sampling, it is only necessary to pull the traction rope 6 to drive the sealing plug 52 to move up and out of the water inlet 401. The operation is simple and convenient, the structural layout is reasonable, and the practicality is high.

[0032] In detail, when the sampling tube 4 enters the water together with the lower part of the mounting rod 3, the elastic force of the spring 53 is used to push the sealing plug 52 into the water inlet 401, thereby achieving a sealing effect and preventing water from entering the sampling tube 4 when the sampling tube 4 enters the water and moves downward.
