Adjustable depth sampling frame structure for environmental engineering water quality monitoring

Abstract

The invention provides an adjustable depth sampling frame structure for environmental engineering water quality monitoring, which comprises a base bracket, a gearbox and sampling pipe heads. The top of the base bracket is fixedly connected with one set of gearbox; a rotating shaft of the gearbox is coaxially and fixedly connected with one set of gear; the lower parts of telescopic rods are tightlyconnected with a set of sampling pipe heads by pipe brackets; and the sampling pipe heads are connected with sampling pumps. By arranging a gear and rack drive mechanism and a driving belt drive mechanism and arranging sliding connection plates and fixed connection plates, when four sets of sampling pipe heads regulate a depth, distances among the sampling pipe heads can be guaranteed to be equal, so that a water body can be uniformly sampled, thereby improving sampling accuracy, reducing an error and facilitating accurate detection management on water quality; and the adjustable depth sampling frame structure can be driven by the gearbox, so that automatic regulation of the sampling depth is implemented and manual labor is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and more specifically relates to an adjustable-depth sampling rack structure for monitoring water quality in environmental engineering. Background technique [0002] In the process of environmental governance, the water quality of the water body needs to be monitored, and the water body needs to be sampled in the process of water quality monitoring. The existing sampling equipment has a variety of structures of manual extraction and automatic extraction. During the sampling process, due to the depth of the water body Different water quality will have certain differences, and it is necessary to sample water quality at different depths. [0003] For example, the application number: CN201510418564.1 pull-type lake water quality research sampler at different depths, which belongs to the technical field of lake water ecology, consists of a sampling unit (1), a lead weight (2...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides an adjustable depth sampling frame structure for environmental engineering water quality monitoring, to solve the problem that the existing sampling device cannot adjust the sampling depth range during the sampling process, and the water at different depths needs to be sampled in stages , In the sampling process, the sampling depth cannot be accurately controlled, and the depth difference of the sampling point is different, resulting in deviations in sampling accuracy, increasing monitoring errors, and inability to accurately analyze and reflect the water quality of the water body.
