Sewage treatment-based sampling device with anti-leakage structure

Abstract

The invention discloses a sewage treatment-based sampling device with an anti-leakage structure, relates to the technical field of sewage sampling, and solves the problems that the existing sewage sampling device is inconvenient to transport, the sampling depth is difficult to confirm and the sampling is inaccurate. The device comprises a main sampling block, two suspension rope connecting bases are fixedly and symmetrically connected to the tops of the two sides of the main sampling block; a connecting frame is mounted on the inner sides of the four guide rods in a sliding manner; the top of the connecting frame is fixedly connected with a main pull rope; the bottom of the connecting frame is fixedly connected with a connecting rod; and the bottom end of the connecting rod is embedded into the inner side of the water inlet base, and the bottom end of the connecting rod is fixedly connected with a sealing plunger. During sampling, the main pull rope is pulled upwards, and the connecting frame can drive the sealing plunger to move upwards again to block the fine hole in the middle of the water inlet seat at the moment, so that after sampling is finished, a sample can be prevented from seeping outwards, sewage at other depths can be prevented from polluting the sample, and sampling is more accurate.

Description

technical field [0001] The invention relates to the technical field of sewage sampling, in particular to a sampling device with an anti-leakage structure for sewage treatment. Background technique [0002] Water pollution sampling, also known as water pollution sampling, refers to the process of taking water samples from polluted water quality according to prescribed methods and a certain proportion. The type and content of substances and other related water quality parameters are used to guide production activities and take relevant measures to reduce water pollution. During the sampling process, a sampler is required for sampling. [0003] For example, the patent application No. 201410596942.0 discloses a mechanical sewage sampler. The upper part of the trigger chamber is provided with a vent hole and a sampling valve. One end of the first piston rod is connected to a trigger needle, and one end of the trigger needle is located outside the casing. The second end of the fi...

Problems solved by technology

[0005] The object of the present invention is to provide a sampling device with an anti-leakage structure based on sewage treatment, so as to solve the problem that the existing sewage sampling devices proposed in the above-mentioned background technology are many It is an integral structure, and some collection devices are large in size and cannot be disassembled, so it is very inconvenient to carry, and it is difficult to confirm the sampling depth of these devices. The sewage is also easy to enter the inside of the device to pollute the sample, and the sample is easy to leak out, which affects the accuracy of sampling.
