[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-11 The present invention provides the following technical solution: a river water environment sampling device, comprising: a sampler body 1 and a collection chamber 10 disposed inside the sampler body 1, an inlet 11 is provided at the bottom of the sampler body 1, an inlet pipe 12 is provided inside the sampler body 1, the inlet 11 and the inlet pipe 12 are vertically aligned, water can flow into the collection chamber 10 through the inlet pipe 12, an outlet is provided on the sampler body 1, and a gate cover 29 is provided at the outlet, opening the gate cover 29 can pour out the water inside the collection chamber 10.

[0035] A gripping rod 27 is installed on the top of the sampler body 1, allowing the operator to insert the sampler body 1 into the water surface. A filter plate 13 is installed at the connection between the water inlet pipe 12 and the water inlet 11. The filter plate 13 filters the water flow, preventing impurities from flowing into the water inlet pipe 12. The sampler body 1 can be disassembled and closed (e.g., ...). Figure 1 As shown in the figure, the sampler body 1 is fixedly connected together by a shaft and a hole (not shown in the figure). The shaft and the hole are interference fit, so that the shaft and the hole can be locked together. The sampler body 1 is made of polytetrafluoroethylene material, and its interior is equipped with a fluororubber-polytetrafluoroethylene composite sealing ring to ensure the overall sealing of the sampler body 1. This is the existing technology and will not be described in detail here.

[0036] The gripping rod 27, the moving shaft 26, and the indicator rod 28 are all telescopic rod structures and can be fixed at a certain height. The lengths of the gripping rod 27, the moving shaft 26, and the indicator rod 28 can be adjusted according to the actual use, thereby improving the practicality of the device. This is existing technology and will not be elaborated on here.

[0037] Please see Figure 1 and Figure 4 The sampler body 1 has a water outlet pipe 16 installed on its top. A connecting column 17 is slidably provided inside the water outlet pipe 16. A cover plate is provided on the top of the connecting column 17 to block the water outlet pipe 16. A sealing ring (not shown in the figure) is provided between the cover plate and the top of the water outlet pipe 16 to seal the water outlet pipe 16 and prevent water from flowing back into the water inlet pipe 12 when the sampler body 1 moves downward. A warning rod 28 is installed on the top of the cover plate.

[0038] The outlet pipe 16 corresponds vertically to the inlet pipe 12. The connecting column 17 extends into one end of the inlet pipe 12 and is equipped with a buoyancy element 18. The buoyancy element 18 is a hemispherical buoyancy ring structure. The sampler body 1 has a channel inside for connecting the inlet pipe 12 and the collection chamber 10. The indicator rod 28 and the cover plate can be made of brightly colored materials to facilitate observation by the operator. This is existing technology and will not be described in detail here.

[0039] After the water fills the collection chamber 10, the buoyancy component 18 can drive the cover plate to move upward through the connecting column 17. The connecting column 17 drives the indicator rod 28 to move upward through the cover plate. When the operator observes that the indicator rod 28 extends out of the water or the indicator rod 29 moves upward, it indicates that the collection chamber 10 is full of water and the device can be recovered.

[0040] The sampler body 1 has a groove 14 at the bottom, which is connected to the water inlet pipe 12. A sealing plate 15 adapted to the water inlet 11 is slidably installed inside the groove 14. The sealing plate 15 is used to open or close the water inlet 11, thereby controlling the water flow into the water inlet pipe 12. A sealing structure (not shown in the figure) is provided between the sealing plate 15 and the water inlet 11. This is the prior art and will not be described in detail here.

[0041] Please see Figure 1-7 The top of the sealing plate 15 is equipped with a cleaning brush, and the sampler body 1 is equipped with a left and right translation mechanism. The left and right translation mechanism is used to drive the sealing plate 15 to move left and right inside the slide groove 14, thereby opening or closing the water inlet 11. At the same time, the sealing plate 15 can clean the filter holes on the filter plate 13 through the cleaning brush to prevent impurities from clogging the filter holes.

[0042] The sampler body 1 has a drive groove 19 inside, which is connected to the inside of the slide groove 14. The left and right translation mechanism is set inside the drive groove 19. The left and right translation mechanism includes a drive gear 21, a drive rack 22, a connecting block 23 and a U-shaped plate 24. The drive gear 21 is rotatably installed inside the drive groove 19, and the drive rack 22 is slidably installed inside the drive groove 19. The drive gear 21 and the drive rack 22 mesh with each other.

[0043] The connecting block 23 and the U-shaped plate 24 are slidably disposed inside the slide groove 14. The U-shaped plate 24 is connected to the sealing plate 15, and the connecting block 23 is connected to the U-shaped plate 24. The drive rack 22 extends into one end of the slide groove 14 and is connected to the connecting block 23.

[0044] Please see Figure 1-3 The forward and reverse rotation of the drive gear 21 enables the drive rack 22 to move left and right. At the same time, the drive rack 22, through the connecting block 23 and the U-shaped plate 24, can drive the sealing plate 15 to move left and right, thereby closing or opening the water inlet 11.

[0045] The sampler body 1 has a drive hole and a through hole inside. The sampler body 1 also has a connecting groove inside for connecting the drive hole and the through hole. The drive hole has a drive component inside, which drives the left and right translation mechanism to perform left and right reciprocating motion. The drive component is connected to the drive gear 21, which drives the drive gear 21 to rotate in both directions.

[0046] The driving component includes a drive shaft 25 rotatably mounted inside the drive hole. A connecting shaft is mounted at the bottom of the drive shaft 25. One end of the connecting shaft rotatably extends into the drive groove 19 and is connected to the drive gear 21. A movable shaft 26 is provided inside the through hole. A spiral groove 251 is provided on the outer circumferential surface of the drive shaft 25. A transmission shaft 261 is provided on the outer circumferential surface of the movable shaft 26. The transmission shaft 261 is inserted into the spiral groove 251.

[0047] Pull the movable shaft 26 upward, and the movable shaft 26 will drive the transmission shaft 261 to move upward within the spiral groove 251. The transmission shaft 261 will drive the drive shaft 25 to rotate through the spiral groove 251. The drive shaft 25 will drive the drive gear 21 to rotate through the connecting shaft.

[0048] Please see Figure 1-10 Working principle: When in use, the operator can insert the sampler body 1 into the river water by holding the rod 27. After it is inserted into the designated position, the operator can pull the moving shaft 26 upward. The moving shaft 26 drives the transmission shaft 261 to move upward in the spiral groove 251. The transmission shaft 261 drives the drive shaft 25 to rotate through the spiral groove 251. The drive shaft 25 drives the drive gear 21 to rotate through the connecting shaft.

[0049] The drive gear 21 drives the drive rack 22 to move. The drive rack 22 can drive the sealing plate 15 to move through the connecting block 23 and the U-shaped plate 24, thereby opening the water inlet 11 and allowing water to enter the water inlet pipe 12. The filter plate 13 filters the water.

[0050] After waiting for a period of time, if the operator does not observe that the connecting column 17 drives the indicator rod 28 through the cover plate or that the indicator rod 28 extends out of the water, the operator can push the moving shaft 26 up and down. The moving shaft 26 drives the drive shaft 25 to rotate in both directions through the transmission shaft 261. The drive shaft 25 drives the drive gear 21 to rotate in both directions through the connecting shaft.

[0051] The drive gear 21 drives the drive rack 22 to move back and forth. The drive rack 22, through the connecting block 23 and the U-shaped plate 24, can drive the sealing plate 15 to move back and forth. The sealing plate 15 can clean the filter holes on the filter plate 13 with a cleaning brush until the indicator rod 28 moves upward or extends out of the water surface, and then the moving shaft 26 is pushed to the bottom (e.g. Figure 3 As shown), at this time, the inlet 11 is closed, and the device is moved out of the water surface by holding the lever 27. Opening the gate 29 can bring out the water inside the collection chamber 10.
