A self-control switching sewage sampling device with adjustable sampling depth

Abstract

The invention discloses a self-control switch type sewage sampling device capable of adjusting the sampling depth. The invention relates to the technical field of factory sewage treatment. The deviceincludes a shell, a liquid storage cavity is formed in the middle of the shell, the middle of the shell is fixedly connected with an electric push rod; and the bottom of the electric push rod is fixedly connected with a piston block matched with the liquid storage cavity. Two symmetrical electromagnets are fixedly connected to the bottom of the shell, a first spring is fixedly connected to an inner wall of the bottom of the shell, a blocking block is fixedly connected to the inner side of the first spring, a magnetic block is fixedly connected to the middle of the blocking block, a liquid inlet is formed in the middle of the bottom of the shell, and two symmetrical second springs are arranged at the inner bottom of the middle of the shell. According to the self-control switch type sewage sampling device capable of adjusting the sampling depth, the electric push rod and the piston block are used in cooperation, when the electric push rod is powered on, the electric push rod can move thepiston block upwards to automatically suck sewage into the liquid storage cavity through the liquid inlet, and therefore, the automatic sampling effect is achieved, the direct contact with the sewageis avoided, and the sewage sampling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of factory sewage treatment, in particular to an automatic control switch type sewage sampling device which can adjust the sampling depth. Background technique [0002] Factory sewage is the industrial sewage produced by the factory in the process of industrial production. The sewage produced in the production process needs to be treated in a centralized manner before it can be discharged into the river. Before the treatment, the sewage needs to be sampled and analyzed, which is convenient and efficient. Treat sewage. [0003] When the current sewage sampling devices are used, most of them are extracted manually, the efficiency of manual extraction is low, and the sewage will get on the hands, which will pollute the hands and cause certain damage, and it is difficult to determine the extraction depth by manual extraction, resulting in The extracted samples are difficult to carry out accurately, and the diff...
