Sampling device for detecting water resources

Abstract

The invention provides a sampling device for detecting water resources. The sampling device comprises a test tube fixing hole and a rubber fixing ring, wherein a rotary handle is mounted on a front end face of a wire reeling device; the rotary handle is in rotary connection with an outer end face of the wire reeling device; the wire reeling device is connected with a lifting handle through a pulling rope; the lifting handle is of a circular-arc strip-shaped structure; two ends of the bottom of the lifting handle are mounted on a top end face of a collection bucket; a counter weight block is mounted at the bottom of the collection bucket; the top of a connection block is mounted on a circular-arc end face of the bottom of the counter weight block through a screw; two silt collection hole parts formed in a silt collection cone are of chamfer structures; the silt collection cone is located at the bottom of the collection bucket; water body sample collection is easy to carry out on a riverat a relatively deep part and a water well through the device, people do not need to slide to the water surface and can immediately carry out collection work on a water body sample at a part which isa relatively far away from the height of the water surface, so that the sample collection work is more convenient.

Description

technical field [0001] The invention belongs to the technical field of water resource sampling, and more specifically relates to a sampling device for water resource detection. Background technique [0002] Due to the rapid development of industry and improper disposal of domestic waste, the water pollution in some areas is relatively serious, and the polluted water will cause serious harm to human health. Therefore, it is necessary to monitor the pollution of the water flow. In this process, it is necessary to use a sampler to collect samples of the water flow to be monitored. [0003] Based on the above, the inventor found through retrieval that there is a similar water resource sampling device, such as a hand-held water quality sampler mentioned in patent application number CN207066790U, which includes a casing, a peristaltic pump and a rotating block, and the inside of the casing A motor is installed, and the side surface of the casing is provided with a telescopic rod,...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a sampling device for water resources detection to solve the problem of the existing similar devices, which have poor sample collection efficiency for deep wells and river water bodies with large height drops, and personnel need to fall to the water surface. In order to sample the water quality, the collection is relatively cumbersome; and the samples collected by the device are too single to effectively collect the silt accumulated at the bottom of the water flow, resulting in too simple collection of data, which may easily lead to the problem that the detected data is not accurate enough
