Description

Technical Field

[0001] The utility model belongs to the technical field of water sampling, and particularly relates to a water body sampling mechanism for environmental detection. Background Technique

[0002] Environmental detection water body sampling refers to the process of collecting a certain amount of water samples from natural environmental water bodies (such as rivers, lakes, reservoirs, and groundwater, etc.) during environmental monitoring, which can represent the entire water body or a certain part of the water body, in order to conduct subsequent analyses of physical properties, chemical compositions, biological indicators, etc.

[0003] Currently, when sampling water bodies, it is often done by staff directly filling water into a container. However, this method can only sample the water body on the water surface and cannot take out the water body in the deep water area, and it is extremely easy to cause mixing, which is not conducive to data analysis during environmental operations and affects the accuracy of detection results.

[0004] To solve the above problems, a water body sampling mechanism for environmental detection is proposed in this application. Content of the Utility Model

[0005] The purpose of the utility model is to provide a water body sampling mechanism for environmental detection, which solves the problems raised in the above background technique.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a water body sampling mechanism for environmental detection, including: a water intake tube and a tube cover; a filter screen is provided between the tube cover and the water intake tube, and a pressing plate is provided inside the tube cover. By blocking the filter screen through the sealing ring on its outer side, the effect of controlling the water inlet state is achieved, so as to facilitate deep water sampling; a partition is provided inside the water intake tube in the region adjacent to the upper end, and a communicating path with the outside is formed by docking the water guiding pipe below it with the conduit below the pressing plate, which is convenient for quantitative water intake for detection and is also convenient for retaining water samples for subsequent comparison.

[0008] Further, a limiting frame is provided above the tube cover, and a pulling rope is installed above it. An electric telescopic device is provided inside the limiting frame, which is used to drive the pressing plate to move up and down.

[0009] Further, a ring frame is provided above the outer ring region of the tube cover, which is used to accommodate the protruding structure above the sealing ring when the pressing plate is retracted.

[0010] Further, a guide rod is provided below the pressing plate, which is docked with the positioning hole inside the partition to achieve a sealing effect to prevent the water in the deep water area from mixing with the water in the shallow water area when the water intake tube is being recovered.

[0011] Furthermore, a convex tube is provided inside the cylinder cover, and a folding tube is provided below the cylinder cover to connect with the convex tube and the water diversion pipe.

[0012] Furthermore, a sealing gasket is provided inside the water diversion pipe adjacent to the upper end, which is used to automatically block the passage to form a seal.

[0013] Furthermore, when the water intake cylinder is at the bottom, the sealing ring is blocking the filter screen. When the water intake cylinder is taking water, the sealing ring is recovered to the upper interior of the cylinder cover. When the water intake cylinder is recovered to the water surface, the sealing ring still blocks the filter screen. At the same time, the guide rod docks with the positioning hole to form a secondary seal.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can drive the sealing ring to move up and down through the electric expansion joint to switch the water intake state of the water intake tube at any time, which is convenient for underwater water intake operation. At the same time, the water intake area can be blocked by the cooperation of the guide rod and the positioning hole to achieve the effect of sealing the internal water body, which is convenient for subsequent transportation and other processing uses;

[0016] The utility model can not only seal the water inlet area, but also drive the catheter to press against the sealing pad to expand it to form an opening. At this time, the water extraction pipe can be directly probed into through the convex pipe to achieve the effect of quantitative extraction without affecting the internal water body, so as to facilitate the use of batch sampling and other processing.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0027] Please refer to Figures 1-4 As shown in the figure, the present invention is a water sampling mechanism for environmental detection, including: a water intake tube 1 and a tube cover 2; a filter screen 3 is provided between the tube cover 2 and the water intake tube 1, and a pressing plate 8 is provided inside the tube cover 2. By blocking the filter screen 3 with the sealing ring 11 on its outer side, the water inlet state can be controlled to facilitate deep water sampling;

[0028] A partition board 10 is provided inside the adjacent upper end area of the water intake tube 1. The conduit 13 below the partition board 10 is docked with the water diversion pipe 16 below the pressing plate 8 to form a passage communicating with the outside, which is convenient for quantitative water sampling for detection and also convenient for retaining water samples for subsequent comparison;

[0029] This embodiment provides a sampling mechanism that can prevent the mixing of deep and shallow water. While using the sealing ring 11 to block the water intake depth, it can also prevent the mixing of water in the deep and shallow areas from affecting the sampling effect. In addition, during the detection operation, the water body can be sealed throughout the process, which is convenient for retaining samples and subsequent data analysis such as comparison, and avoids the problem of waste caused by a one-time input of water samples.

[0030] Among them, a limit frame 4 is provided above the tube cover 2, and a pull rope 5 is installed above it. An electric telescopic device 9 is provided inside the limit frame 4, which is used to drive the pressing plate 8 to move up and down, and different use effects of the sampling tube 1 can be achieved by adjusting its use height.

[0031] Among them, a ring frame 7 is provided above the outer ring area of the barrel cover 2, which is used to accommodate the protruding structure above the sealing ring 11 when the pressing plate 8 is retracted. When the sealing ring 11 moves up and down, it will automatically scrape and clean the filter screen 3 to prevent large particle impurities from blocking the mesh holes.

[0032] Among them, a guide rod 12 is provided below the pressing plate 8, which is docked with the positioning hole 15 inside the partition plate 10, achieving a sealing effect to prevent the water in the deep water area from mixing with the water in the shallow water area when the water intake barrel 1 is being retracted, so that the sampled water is sealed inside the area below the partition plate 10 of the sampling barrel 1.

[0033] Among them, a convex pipe 6 is provided inside the barrel cover 2, and a folding pipe 14 is provided below the barrel cover 2, which is docked with the convex pipe 6 and the water inlet pipe 16, through which the water sample can be taken out by connecting an external water extraction pipe at any time.

[0034] Among them, a sealing gasket 17 is provided inside the water inlet pipe 16 near the upper end, which is used to automatically block the passage to form a seal.

[0035] Among them, when the water intake barrel 1 is in the lower position, the sealing ring 11 blocks the filter screen 3. When the water intake barrel 1 is taking water, the sealing ring 11 is retracted to the upper part inside the barrel cover 2. When the water intake barrel 1 is retracted to the water surface, the sealing ring 11 still blocks the filter screen 3, and at the same time, the guide rod 12 is docked with the positioning hole 15 to form a secondary seal.

[0036] It can be understood that the utility model can control the water intake depth, prevent the water body in the deep and shallow areas from mixing and affecting the sampling effect, and can also keep the water body sealed throughout the detection operation, which is convenient for retaining samples and subsequent data analysis such as comparison, avoiding the problem of waste of a one-time investment of water samples.

[0037] A specific application of the operation process of this embodiment is as follows: When in use, first, by using the sealing ring 11 to block the filter screen 3, the water intake barrel 1 can take water in the deep water area. Then, the electric telescopic device 9 drives the pressing plate 8 to press down, so that the guide rod 12 is inserted into the positioning hole 15 to form a seal, preventing it from mixing with the water on the water surface during retraction and ensuring the accuracy of subsequent detection data. In addition, by further pressing down the pressing plate 8, the conduit 13 can press against the sealing gasket 17 to form an opening inside it. At this time, the water extraction pipe can be directly inserted into the water inlet pipe 16 through the convex pipe 6 to extract the water sample, avoiding the situation where a sample cannot be retained due to a one-time investment.
