Description

Technical Field

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

[0002] When carrying out ecological environmental protection, a water quality sampling device is needed to sample the water quality.

[0003] However, most of the existing water quality sampling devices for ecological environment protection are difficult to adjust when sampling water quality. Relevant staff are required to move the entire device during adjustment. At the same time, the sealing of the sampling tube cannot be guaranteed when sampling water quality at different depths, and water quality at other depths is easily mixed in, resulting in mediocre sampling effect and certain limitations. It can be seen that there is an urgent need for a water quality sampling device for ecological environment protection to solve the above-mentioned technology.

[0004] For example, Chinese patent CN216771149U discloses a water quality sampling device for ecological environmental protection, comprising a sampling seat, an adjusting mechanism fixedly mounted on the top of the sampling seat, a sampling mechanism disposed on the side of the adjusting mechanism, the adjusting mechanism comprising an adjusting cylinder fixedly mounted on the top of the sampling seat, the extended end of the adjusting cylinder fixedly connected to the adjusting seat. This water quality sampling device for ecological environmental protection, by providing a sampling mechanism and a structure at the sampling mechanism, enables the sampling mechanism to ensure the sealing of the sampling tube before sampling when performing relevant water quality sampling, thereby avoiding sampling water quality at an unnecessary position and ensuring the final sampling effect. At the same time, when the sampling tube reaches the appropriate position, the sealing state of the sampling tube can be easily released by driving a motor, thereby performing rapid sampling, having advantages such as good sampling effect, and solving the problem of mediocre sampling effect in existing devices.

[0005] However, the device cannot achieve accurate sampling and cannot precisely control the amount of sampling. Utility Model Content
