Water detecting and sampling apparatus for environmental engineering

Abstract

The invention discloses a water detecting and sampling apparatus for environmental engineering, and mainly relates to the field of water detection. The water detecting and sampling apparatus comprisesa movable support which is provided with wheels at the bottom and a telescopic tilt bar on the upper side; a mount plate is arranged at the end of the tilt bar and provided with telescopic rods and amount block is arranged at the bottoms of the telescopic rods; sampling bottles are arranged under the mount block and are provided with openings at side walls; sealing devices are arranged at the openings of the sampling bottles respectively, each sealing device comprises a sealing plate capable of closing the opening of the corresponding sampling bottle, a water inlet is formed at the side, close to the corresponding sampling bottle, of the sealing plate, and each sealing plate is provided with a through groove; a motor, a first lead screw and a first nut are arranged in the through groove,the first nut is provided with a pusher rod which is connected with a seal plug, the pusher rod moves to drive the seal plug to move along the through groove so that the seal plug can seal the waterinlet, and one side of the seal plug is connected with an air inflating hole which is further connected with an air inflating pump. The water detecting and sampling apparatus has the advantages of realizing sampling in the designated area to guarantee sampling accuracy as much as possible so as to meet quality on water detection.

Description

technical field [0001] The invention relates to the field of water body detection, in particular to a water body detection and sampling device for environmental engineering. Background technique [0002] Water is the source of life. Human beings cannot do without water in their daily life and production activities. The quality of drinking water is closely related to human health. With the development of society and economy, the progress of science and the improvement of people's living standards, people's requirements for the quality of drinking water have been continuously improved, and the standards for drinking water quality have also been continuously developed and improved accordingly.

Problems solved by technology

[0003] Existing water sampling tests usually only sample the water on the surface, and the test data is not representative. Under special circumstances, it is necessary to sample the lower water body. It is necessary to manually drive the boat to lower the water pump in the center of the lake or manually dive to take samples, which is troublesome to operate. , time-consuming and labor-intensive, and it is not convenient to sample water at different depths by putting in a water pump to take water samples, and the water quality monitoring is not standard enough

In addition, using the hanging basket to place the sampling bottle into the water sampling, during the descent of the sampling bottle, before reaching the designated water intake area, water often has entered the sampling bottle, resulting in inaccurate sampling

In addition, when sampling, often only one sampling bottle can be put in at a time, so that only one point of water sample can be taken, which has certain limitations for determining the water quality of the water area

If multiple sampling bottles are put in at the same time, it is necessary to drive multiple devices at the same time, which has certain requirements for space, and it is not easy to ensure that multiple sampling bottles arrive at the designated area at the same time. Affect the water quality in the sampling water area and affect the accuracy of sampling
