Description

Technical Field

[0001] This invention relates to the field of water quality testing technology, specifically to an environmental testing device for water conservancy projects. Background Technology

[0002] Water quality testing refers to the work of testing the physicochemical properties and microorganisms contained in groundwater during water supply hydrogeological exploration. It provides data for the development and utilization of groundwater and for determining its corrosiveness to building structural materials. Local water quality testing and analysis are usually required before the construction of water conservancy projects.

[0003] Publication No. CN111649990A discloses a groundwater sampling device, including a groundwater receiving section, which is a pipe body sealed at the top and open at the bottom; a groundwater sampling control section, which is a valve body disposed at the bottom of the pipe body; the bottom inlet and top outlet of the valve body are connected through a valve cavity; a valve core with a spherical bottom is disposed in the valve cavity; the top of the valve core is connected to a support member disposed in the valve cavity through an elastic element; the bottom surface of the valve core matches the spherical structure at the inlet end of the valve cavity; a groundwater inlet section, which is a water inlet net with a cylindrical structure disposed at the bottom of the valve body; a counterweight section, which is a counterweight block disposed at the bottom of the water inlet net; and an impurity sampling section, which is disposed in the pipe body. The device features a permeable cylinder on its top surface, with a filter screen for impurity adhesion fitted to the outside. A suspension part, a perforated connector at the top of the permeable cylinder for connecting to a lifting mechanism, allows for convenient sampling at a fixed water depth, ensuring accurate test results. However, in practical use, this device and existing equipment cannot separate water samples at different depths within the sampling device based on variations in sampling depth. This results in water samples from different depths mixing after sampling, affecting the actual water quality test results. Existing methods require multiple samplings at different depths, which is cumbersome. Therefore, there is room for improvement in the sampling efficiency of this device. Summary of the Invention

This allows the device to separate the samples under the push of air pressure and water level, avoids the mixing of water samples, and ensures the normal operation of the device.

[0052] Working principle: The device is placed on the shore of the lake. A sealing film is then wrapped around the support rod 341 to ensure the internal seal of the sampling device 3. The control center 20 activates the rotary drive assembly 21, which drives the rotating shaft 210 to rotate. The rotating shaft 210 rotates the first movable wheel 22, which in turn rotates the first screw 23. The first screw 23 rotates, causing the push rod 230 to move downwards. This downward movement of the push rod 230 moves the sampling device 3, extraction tube 32, and sampling head 33 downwards, extending them into the lake to the desired sampling depth. The control center 20 then activates the pump 31, which extracts water samples from the lake through the extraction head and extraction tube 32 to the transport pipe 34. The samples are then transported via… The transport pipe 34 transports the water sample to the spray plate. Since the sampling device 3 is a sealed space with constant air pressure, the water sample sprayed onto the bottom sampling device 3 will cause the water level inside to rise continuously. The spring 511 has a relatively small stiffness coefficient. The continuous rise in water level causes the air pressure inside the bottom collection device 5 to increase continuously. The combined effect of air pressure and water level can push the separation plate 52 upward through the slide rod 521 and the slide groove. The spring 511 undergoes elastic deformation. The upward movement of the separation plate 52 moves it downward relative to the toothed plate 510. The downward movement of the toothed plate 510 drives the gear 531 to rotate through the second shaft 53. The rotation of the gear 531 drives the third bevel gear 532 to rotate. The rotation of the third bevel gear 532 drives the fourth bevel gear 531 to rotate. The bevel gear 55 and the second screw 550 rotate. The rotation of the second screw 550 drives the second baffle 56 to extend and move from the separation plate 52. At this time, the telescopic rod 540 and the side plate 54 limit the movement of the second baffle 56 and assist the second baffle 56 in moving. The two second baffles 56 move relative to each other and are engaged by the locking block and the second locking groove. At this time, the water inside the bottommost collecting device 5 is collected, and the middle collecting device 5 and the bottommost collecting device 5 are isolated by the bottommost separation plate 52. Then, the user can adjust the water level sampling at different depths by turning on the rotation drive assembly 21 again. At this time, the bottom of the middle sampling device 3 is isolated by the separation plate 52 inside the bottommost collecting device 5, and the top is isolated by the separation plate 52 inside the bottommost collecting device 5. The spray plate continuously sprays water to prevent air from entering, meaning that the internal environment of the middle collection device 5 is the same as that of the bottom collection device 5. Similarly, the user can collect water samples at different depths and avoid mixing of water samples at different depths. When sampling and testing, the user only needs to pull open the two second baffles 56 at the top collection device 5 to remove the sample. Then, the top collection device 5 can be removed through the connector 50, the clamp 500 and the first clamping slot to remove the water sample from the middle collection device 5. Thus, the device can separate samples at different depths according to the changes in different sampling depths, avoiding mixing of water samples at different depths, which would reduce the accuracy of water quality testing, improve the sampling effect of the device, and make it easier for users to use.

[0053] When the first movable wheel 22 rotates, it drives the second movable wheel 25 to rotate via the movable belt 24. The rotation of the second movable wheel 25 drives the first bevel gear 26 to rotate via the first connecting rod 250. The rotation of the first bevel gear 26 drives the second bevel gear 27 to rotate. The rotation of the second bevel gear 27 drives the first rotating rod 270, the second connecting rod 271, and the gear plate 272 to rotate. The rotation of the gear plate 272 drives the return plate 28 to perform a linear reciprocating motion from top to bottom or from bottom to top. The movement of the return plate 28 drives the second fixed rod 280 and the fixed plate 28. The movable plate 41 and the moving plate 41 reciprocate linearly. The moving plate 41 reciprocates linearly, causing the through rod 411 to continuously penetrate into the filter holes of the filter plate 40. The filter plate 40 is used to remove suspended matter from the surface of the sample. The penetration of the through rod 411 can prevent the filter holes in the filter plate 40 from becoming clogged. At the same time, the through holes can also share some of the filtration effect of the filter plate 40. This allows the device to clean the suspended matter on the surface of the water sample while preventing the device from becoming clogged and reducing the sampling efficiency of the device. This improves the sampling effect and the accuracy of sample detection, making it easier for users to use.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
