Problems solved by technology

[0002] The water quality sampler is a necessary device for collecting water quality samples. It is widely used in the field of environmental protection monitoring. It is used for sampling and testing the water quality of rivers, rivers, lakes, and enterprise discharge water, such as ammonia nitrogen, total nitrogen, total phosphorus, and heavy metals. In order to more accurately understand the water quality conditions at that time, it is necessary to accurately sample within a certain water area or at different water depths to make the collected water samples more representative. Containers such as glass bottles continue to sample, and sampling at different depths cannot be achieved, so the practicability is not strong

Embodiment Construction

[0021] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0022] Such as figure 1 As shown, a sampling device with good sealing effect includes a fixed box 1, a moving plate 2, a sealing mechanism and a limit mechanism, the fixed box 1 is vertically arranged, and the moving plate 2 is horizontally arranged in the fixed box 1, The moving plate 2 is slidingly connected with the fixed box 1, the top of the fixed box 1 is provided with a communication hole, the sealing mechanism is arranged above the moving plate 2, and the limit mechanism is arranged at the bottom of the fixed box 1 .

[0023] Here, the sealing of the fixed box 1 is realized by the sealing mechanism, and the fixed box 1 is sampled in waters of differe...

Abstract

The invention relates to sampling equipment with a good sealing effect, the sampling equipment comprises a fixed box, a moving plate, a sealing mechanism and a limiting mechanism, the sealing mechanism comprises a first spring, a tension meter, a sealing plate, an ejector pin and an adjusting assembly, and the limiting mechanism comprises a push rod, a sliding rod, a floating ball and a moving assembly. According to the sampling equipment with the good sealing effect, the fixed box is sealed through the sealing mechanism, and the restoring force of the first spring is controlled by adjusting the distance of the movable plate, so that sampling is performed on the fixed box in water areas with different depths, the use practicability is improved, and a floating ball is moved through the buoyancy of water. At the moment, the buoyancy of the floating ball is greater than the restoring force of the first spring and the pressure of water, so that the fixed box can be sealed, the volume of the main body in the fixed box can be controlled, and meanwhile, the main body at other depths is prevented from entering the fixed box in the moving-out process to influence the detection effect, and the detection accuracy is improved.

Description

technical field [0001] The invention particularly relates to a sampling device with good sealing effect. Background technique [0002] The water quality sampler is a necessary device for collecting water quality samples. It is widely used in the field of environmental protection monitoring. It is used for sampling and testing the water quality of rivers, rivers, lakes, and enterprise discharge water, such as ammonia nitrogen, total nitrogen, total phosphorus, and heavy metals. In order to more accurately understand the water quality conditions at that time, it is necessary to accurately sample within a certain water area or at different water depths to make the collected water samples more representative. Containers such as glass bottles continue to sample, and sampling at different depths cannot be achieved, so the practicability is not strong. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sampling device w...
