[0002] Water is indispensable for human social life and production activities. The quality of drinking water is closely related to human health. Water used for different purposes, such as industrial use, landscaping, and agriculture, has different quality requirements, making water sampling and monitoring particularly important. By collecting and analyzing water samples, we can evaluate multiple indicators of water bodies, including chemical composition, physical properties, and microorganisms, quantitatively assess the water quality characteristics, and provide timely warnings and responses to water pollution problems.
[0003] When collecting water samples, it is necessary to sample at different depths based on the characteristics of different pollutants. Currently, most commonly used water sampling tools can only sample the upper water layer. However, the amount of pollutants contained in water layers at different depths may vary. Collecting only upper water samples for testing is somewhat accidental and one-sided, and cannot accurately guarantee the precision of water quality testing. Utility Model Content
[0004] To address the aforementioned problem that current water sampling devices can only sample upper-level water sources, resulting in insufficient comprehensiveness and accuracy of the collected samples, this invention proposes a novel water sampling device. The device includes a water collection box with several permeable holes on one side surface. A water outlet groove is formed along the length of the side surface of the water collection box opposite to the permeable holes. Several sampling tubes are also equidistantly arranged on the side surface of the water collection box with the water outlet groove. The inlet of each sampling tube is inserted into the water outlet groove. A baffle plate is slidably connected inside the water collection box, and the inlet of each sampling tube abuts against the baffle plate.
[0005] A further feature of this invention is that: two guide grooves are provided on the surface of the water collection box near the water outlet hole, the two guide grooves are symmetrically arranged about the water outlet hole, and the baffle plate is slidably connected in the two guide grooves; the top of the water collection box is provided with an insertion hole adapted to the baffle plate, the top of the baffle plate extends out of the water collection box through the insertion hole, and the top of the baffle plate is provided with a pull handle.
[0006] A further feature of this invention is that a limiting part is provided at the bottom end of the baffle plate, and the limiting part is provided perpendicular to the baffle plate to prevent the baffle plate from sliding out of the water collection box.
[0007] A further feature of this invention is that: two sliding grooves are provided on the outer surface of the water collection box on one side where the water outlet hole is opened, and the two sliding grooves are symmetrically arranged about the water outlet hole; the water inlet end of the sampling tube is provided with two wing plates adapted to the sliding grooves, and the two wing plates are slidably connected in the two sliding grooves respectively.
[0008] A further feature of this invention is that: a threaded hole is provided on the wing plate, and an avoidance groove is provided on one side wall of the slide away from the water collection box. The avoidance groove is provided corresponding to the threaded hole. A set screw is threaded into the threaded hole, and the nut of the set screw is provided on the outside of the slide.
[0009] A further feature of this invention is that the sampling tube has an outlet hole at one end away from the inlet, and a plug is inserted into the outlet hole.
[0010] A further feature of this invention is that the plug is made of an elastic rubber material.
[0011] A further feature of this invention is that the inlet end of the sampling tube is provided with an inlet portion adapted to the outlet slot, the inlet is provided on the inlet portion, and the sampling tube is set at a certain angle to the inlet portion so that the outlet is set lower than the inlet portion.
[0012] A further feature of this invention is that an extension rod is provided at the top of the water collection box.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. By using the baffle plate, multiple sampling tubes can be sent to the water surface. Since the multiple sampling tubes are equidistant, different sampling tubes are located in different water layers. Pulling the baffle plate upwards can open the inlet of the sampling tube, allowing water to flow into the sampling tube, thus achieving the purpose of sampling different water layers. After sampling is completed, push the baffle plate downwards to block all inlets and prevent water from flowing out of the sampling tube when it is pulled upwards.
[0015] 2. By combining the chute and the wing plate, the height of the sampling tube can be adjusted up and down, thus enabling this application to meet different sampling needs and making it more applicable. Attached Figure Description

Detailed Implementation
[0029] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0030] This invention proposes a novel water sampling device, comprising a water collection box 1, which is rectangular in shape. A plurality of permeable holes 11 arranged in a matrix are formed on one side surface along the length of the water collection box 1, allowing water to flow into the water collection box 1 through the permeable holes 11. A water outlet hole 12 is formed on the side surface of the water collection box 1 opposite to the permeable holes 11, and is parallel to the long side of the water collection box 1, with the outlet hole 12 located in its central part.
[0031] Several sampling tubes are equidistantly arranged on one side surface of the water collection box 1 where the water outlet hole 12 is opened. The inlet of the sampling tube is inserted into the water outlet hole 12 to achieve communication with the water collection box 1. A baffle plate 3 is slidably connected inside the water collection box 1. The inlet of the sampling tube abuts against the baffle plate 3, thus blocking the inlet of the sampling tube.
[0032] Two guide grooves 13 are welded on one side of the water collection box 1 near the water outlet hole 12. The guide grooves 13 are set parallel to the water outlet hole 12. The cross section of the guide grooves 13 is set in an "L" shape. The two guide grooves 13 are symmetrically arranged about the water outlet hole 12. The baffle plate 3 is slidably connected in the two guide grooves 13.
[0033] The top of the water collection box 1 is provided with an insertion hole 14 that is compatible with the baffle plate 3. The baffle plate 3 is provided with an insertion hole so that the top of the baffle plate 3 extends out of the water collection box 1. The top of the baffle plate 3 is integrally connected with a pull handle 31 for pulling the baffle plate 3 to move.
[0034] The bottom end of the baffle plate 3 is integrally provided with a limiting part 32. The limiting part 32 is set perpendicular to the baffle plate 3. When the baffle plate 3 is pulled upward, the limiting part can prevent the baffle plate 3 from being pulled out of the insertion hole 14, that is, prevent the baffle plate 3 from sliding out of the water collection box 1.
[0035] Two sliding grooves 15 are welded to the outer surface of one side of the water collection box 1 where the water outlet hole 12 is located. The sliding grooves 15 are parallel to the water outlet hole 12 and are symmetrically arranged about the water outlet hole 12. The cross-section of the sliding grooves 15 is "L" shaped. Two wing plates 21 adapted to the sliding grooves 15 are welded to the water inlet end of the sampling tube. The two wing plates 21 are symmetrically arranged about the sampling tube and are slidably connected to the two sliding grooves 15 respectively.
[0036] The wing plate 21 has a threaded hole 211, and the slide groove 15 has a relief groove 151 on one side wall away from the water collection box 1. The relief groove 151 is set corresponding to the threaded hole 211. The threaded hole 211 is threaded with a set screw 4. The nut of the set screw 4 is set on the outside of the slide groove 15. The set screw 4 can press the wing plate 21 tightly into the slide groove 15, thereby realizing the positioning of the collection tube 2.
[0037] The sampling tube has an outlet hole 22 at the end opposite to the inlet. A plug 5 is inserted into the outlet hole 22 to block the outlet. The plug 5 is made of elastic rubber material.
[0038] The sampling tube has an integrated inlet section 23 at its inlet end that matches the outlet hole 12. The inlet is located on the inlet section 23, which is inserted into the outlet hole 12 to connect the sampling tube 2 to the water collection box 1. The sampling tube 2 and the inlet section 23 are set at a certain angle so that the outlet hole 22 is lower than the inlet section 23.
[0039] This not only allows water to flow quickly into the sampling tube, but also allows the water in the sampling tube to be released more quickly.
[0040] The top of the water collection box 1 is also welded with an extension rod 16 for holding and extending the water collection box 1 into the water inlet.
[0041] Usage procedure: First, insert the baffle plate 3 into the water collection box 1 so that the baffle plate 3 blocks the water inlet of the collection pipe 2. Then, hold the extension rod 16 and send the water collection box 1 underwater.
[0042] Secondly, after the water collection box is delivered to the designated location, let it stand for a period of time to avoid turbulence that could cause sampling errors when the water collection box 1 is inserted underwater. Then, pull the baffle plate 3 upwards using the handle 31 to open the inlets of all the sampling tubes 2, allowing water to flow into the sampling tubes. Observe the water surface; when no more bubbles emerge from the water surface, it indicates that the sampling tube is full.
[0043] Finally, push the baffle plate 3 downwards to block the inlets of all sampling tubes. Then, pull the water collection box 1 out of the water and release the sampled water from the sampling tubes by removing the plug 5.
[0044] In summary, this invention, through the obstruction of the baffle plate 3, can deliver multiple sampling tubes to the water surface. Since the sampling tubes are equidistantly arranged, different tubes are located at different water layers. Pulling the baffle plate 3 upwards opens the inlets of the sampling tubes, allowing water to flow into them and achieving the purpose of sampling different water layers. After sampling is complete, pushing the baffle plate 3 downwards blocks all inlets, preventing water from flowing out of the sampling tubes when pulled upwards. The cooperation between the slide groove 15 and the wing plate 21 allows for vertical adjustment of the height of the sampling tube 2, thus enabling this invention to meet different sampling needs and enhancing its applicability.
