Description

Technical Field

[0001] The utility model relates to the technical field of surface water sampling, in particular to a surface water monitoring and sampling device. Background Art

[0002] Surface water exists on the earth's surface and is water exposed to the atmosphere. It is the general term for four water bodies: rivers, glaciers, lakes, and swamps, also known as "terrestrial water". It is one of the important sources of human domestic water. Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) and various industrial wastewaters, etc. When monitoring surface water, a surface water sampling device is needed to sample the water source.

[0003] The existing surface water sampling device cannot perform stratified sampling of surface water during use and needs to take samples in this way to complete. Moreover, when the sampling container tilts during the process of taking out the water sample, the water inside will overflow. Therefore, we design a surface water monitoring and sampling device. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a surface water monitoring and sampling device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A surface water monitoring and sampling device includes a sampling pipe, an outer sleeve is sleeved on the outer wall of the sampling pipe, the sampling pipe and the outer sleeve are rotationally connected, a number of first sampling ports are equidistantly arranged on the outer wall of the sampling pipe, second sampling ports corresponding to the first sampling ports are equidistantly arranged on the outer wall of the outer sleeve, a manual drain valve is installed below each first sampling port on the outer wall of the sampling pipe, and a sliding groove for the manual drain valve to move is arranged on the outer wall of the outer sleeve.

[0007] As a further scheme of the utility model, a screw head is fixed at the bottom of the sampling pipe, a hole for the screw head to pass through is arranged at the bottom of the outer sleeve, and the screw head is threadedly connected with a torsion cap.

[0008] As a further scheme of the utility model, a fixing ring is fixed on the outer wall of the top of the sampling pipe, a torsion spring is fixed on the outer wall of the fixing ring, and the bottom of the torsion spring is fixed with the top outer wall of the outer sleeve.

[0009] As a further scheme of the utility model, an upper handle rod is fixed on the outer wall of the top of the sampling pipe, and a lower handle rod is fixed on the top outer wall of the outer sleeve.

[0010] As a further solution of the utility model, in the natural state of the torsion spring, the first sampling port and the second sampling port are in a blocked state. A cavity is provided in each second sampling port, and a filter sleeve is arranged in the cavity. By providing a cavity on the inner wall of the outer sleeve, the filter sleeve is located inside the cavity, and the filter sleeve can filter impurities in the water body to prevent blockage. At the same time, the filter sleeve can be toggled to facilitate sliding upward to open, so as to clean the outer wall and inner wall of the filter sleeve including the inside.

[0011] As a further solution of the utility model, a toggle block is fixed at the bottom of the outer wall of the filter sleeve.

[0012] The beneficial effects of the utility model are as follows:

[0013] For the utility model: due to the adoption of the sampling tube, upper handle, first sampling port, outer sleeve, lower handle, second sampling port, chute, manual drain valve and the filter sleeve arranged in the chute, when sampling, it can penetrate into the water, so that the first sampling port and the second sampling port correspond, and the water body enters the inside of the sampling tube through the second sampling port and the first sampling port, above each partition board, and the sampling is completed. Take out the device, release the restriction on the upper handle and the lower handle, the torsion spring resets, the first sampling port and the second sampling port are misaligned, and the outer sleeve blocks the first sampling port, playing a certain blocking role. At the same time, the corresponding manual drain valve can be opened to drain the liquid, so as to realize multi-stage sampling and selectively discharge the water body of the required stage, which is convenient and practical;

[0022] Referring to Figures 1 - 4 , a surface water monitoring and sampling device includes a sampling tube 1. An outer sleeve 2 is sleeved on the outer wall of the sampling tube 1. The sampling tube 1 and the outer sleeve 2 are rotatably connected. A plurality of first sampling ports 103 are equidistantly arranged on the outer wall of the sampling tube 1. A plurality of second sampling ports 203 corresponding to the first sampling ports 103 are equidistantly arranged on the outer wall of the outer sleeve 2. A manual drain valve 6 is installed below each first sampling port 103 on the outer wall of the sampling tube 1.

[0026] In this embodiment, in the natural state of the torsion spring 4, the first sampling port 103 and the second sampling port 203 are in a blocked state. A cavity opening 10 is formed in each second sampling port 203, and a filter sleeve 9 is arranged in the cavity opening 10. By forming the cavity opening 10 on the inner wall of the outer sleeve 2 and arranging the filter sleeve 9 inside the cavity opening 10, the filter sleeve 9 can play a role in filtering water impurities, preventing blockage. At the same time, the filter sleeve 9 can be toggled, which is convenient to slide up and open to realize the cleaning of the outer wall and inner wall of the filter sleeve 9 included inside.

[0027] In this embodiment, a toggle block is fixed to the bottom of the outer wall of the filter sleeve 9 .

Through the above-mentioned structural design, when sampling, the device can be first immersed in water, and then the upper handle bar 101 and the lower handle bar 201 are moved to make the sampling tube 1 and the outer sleeve 2 relatively close. Rotate, the first sampling port 103 and the second sampling port 203 correspond, the water enters the interior of the sampling tube 1 through the second sampling port 203 and the first sampling port 103, and is located above the inner partition 5, and the sampling is completed. The restrictions on the upper handle 101 and the lower handle 201 are released, and the torsion spring 4 is reset.
