[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flows, prevent floods and waterlogging, and regulate and distribute water to meet people's needs for water resources in life and production. In order to ensure water quality safety, the water conservancy industry often needs to sample and analyze water.

[0003] There are many kinds of sampling devices. Due to the different sampling objects, different water sampling devices are derived, such as buckets used to collect surface water samples and Nansen water samplers commonly used to collect water samples from layers below the water surface. In the prior art, for different depths of the water surface, it is usually necessary to set marks at the corresponding positions of the lifting ropes, and sampling is performed by sinking the sampling device into the water until the mark coincides with the water surface. The mark position is controlled by manually retracting and releasing the lifting rope, and the coincidence state of the mark position with the water surface is observed.

[0024] In this embodiment, a bracket 5 is provided, and a winding shaft 6 is rotatably installed in the bracket 5. A winding roller 8 is connected to the surface of the winding shaft 6. A traction rope 9 is wound around the winding roller 8. The traction rope 9 is used to connect a group of collecting barrels 27 to enter the water body for sampling.

[0025] Start the motor 7, loosen the traction rope 9, and the collecting bucket 27 sinks in the water body by its own weight. In order to ensure the stability of the traction direction of the traction rope 9, a support arm 14 is provided on one side of the bracket 5. By providing a reinforcing rib plate 16, the stable sinking of the traction rope 9 and the collecting bucket 27 at one end of the traction rope 9 is ensured.

[0026] The counterweight components are symmetrically arranged on both sides of the sampling component. When the counterweight components change their own weight, the sampling component stays at different depths in the water body; The counterweight assembly includes two groups of storage pipes 17 for filling counterweight materials and a telescopic tube connected to one end of the storage pipe 17 through a bent pipe 23. The storage pipe 17 is arranged on one side of the support arm 14 through a fixed support plate 19 and a fixed ear plate 20. The bottom end of the telescopic roller is connected to a counterweight box 28, and a support plate 35 is slidably installed in the counterweight box 28. A push plate 21 is slidably connected in the storage pipe 17, and a pull rope 22 is fixedly connected to one side of the push plate 21.

[0027] In this embodiment, counterweight boxes 28 are connected to both sides of the collecting barrel 27, and a telescopic tube is connected above the counterweight box 28. The top of the telescopic tube is connected to a storage tube 17, and counterweight materials are placed in the storage tube 17. When the traction rope 9 is pulled down by the collecting barrel 27, the pushing plate 21 pushes the counterweight material into the telescopic tube and then into the counterweight box 28, which increases the dead weight of the collecting barrel 27 and enables the collecting barrel 27 to sink to the water depth required for monitoring. There is no need to tie and release the traction rope 9 multiple times to adjust the depth position. The collecting barrel 27 sinks to the corresponding depth position according to the placement of the counterweight material, and the solenoid valve in the sampling port 31 is controlled to open and close. After sampling is completed, the motor 7 is started to pull the collecting barrel 27 up.

[0028] It should be noted that since a support plate 35 is provided in the counterweight box 28, when the motor 7 drives the traction rope 9 to reel in, the traction rope 9 drives the connecting rod 11 to pull the pushing plate 21 to reset, and the support plate 35 is pulled to squeeze the counterweight material back into the storage tube 17 through the telescopic tube of the counterweight box 28, and the counterweight material can be reused.

[0029] A traction block 10 is fixedly installed on the surface of the traction rope 9, and connecting rods 11 are symmetrically arranged on both sides of the traction block 10. One end of the connecting rod 11 extends into the storage tube 17 and is fixedly connected to the push plate 21. The storage tube 17 is provided with a through groove that slides with the connecting rod 11, and an accordion plate 18 is fixedly installed in the through groove. A moving block 12 is fixedly installed on the surface of the connecting rod 11, and a slider 13 is connected to the bottom of the moving block 12. A slide groove 15 is provided in the support arm 14, and the slider 13 and the slide groove 15 are matched.

[0030] In this embodiment, a traction block 10 is provided on the surface of the traction rope 9, and connecting rods 11 are connected on both sides of the traction block 10. The connecting rod 11 is connected to the pushing plate 21 of the storage tube 17, and pushes the counterweight material into the counterweight box 28 along with the movement of the heel. The connecting rod 11 penetrates the storage tube 17 and is connected with the pushing plate 21. Therefore, an accordion plate 18 is provided in the through groove of the storage tube 17 to ensure the normal movement of the connecting rod 11 while avoiding the leakage of the internal counterweight material.

[0031] The telescopic tube comprises an outer tube 38 and an inner tube 39 which are sealed and slidably connected. A limiting groove 41 is provided in the outer tube 38 , and bosses 40 are provided at both ends of the inner tube 39 . The bosses 40 are slidably connected in the limiting grooves 41 .

[0032] In this embodiment, the outer tube 38 and the inner tube 39 are arranged to slide in sequence to ensure that during the sinking of the counterweight box 28, the telescopic tube can not only transport the counterweight material, but also change its length following the rise and fall of the counterweight box 28.

[0033] A rotating shaft 36 is rotatably connected inside the counterweight box 28 , both ends of the rotating shaft 36 pass through the outside of the counterweight box 28 , and both ends of the rotating shaft 36 are fixedly connected to impellers 37 , one set of impellers 37 is rotatably arranged on one side of the sampling port 31 .

[0034] In the water body, the water flow has a certain flow rate. When the water flow passes through the rotating shaft 36, it can drive the impeller 37 to rotate. During the rotation of the impeller 37, the algae impurities can be entangled to prevent them from entering the sampling port 31 as much as possible to cause blockage.

[0035] An anti-blocking component for sampling and dredging is provided in the sampling component, and the anti-blocking component includes a barbed wire 29, and barbs 34 are equidistantly and cross-arranged on the surface of the barbed wire 29. One end of the barbed wire 29 is fixedly connected to a positioning frame 30, and the positioning frame 30 is fixedly installed on the outer wall of the outer tube 38 at the top of the telescopic tube. The barbed wire 29 passes through the sampling port 31 and extends into the collecting bucket 27, and the barbed wire 29 passes through the collecting bucket 27 and extends to the outside of the collecting bucket 27. A limiting ball 33 is fixedly installed at one end of the barbed wire 29.

[0036] In this embodiment, a positioning frame 30 is fixedly installed on the outer wall of the outer tube 38 at the top of the telescopic tube, and one end of the barbed wire 29 is fixedly connected to the positioning frame 30. When the bottom end of the telescopic tube sinks and is stretched following the counterweight box 28, the barbed wire 29 generates a sliding rod relative to the sampling port 31. Barbs 34 are provided on the surface of the barbed wire 29, so that algae impurities that may be deposited in the sampling port 31 can be effectively discharged, thereby further preventing the sampling port 31 from being blocked and ensuring the sampling efficiency.

[0037] A filter box 32 is fixedly installed at the center of the collection barrel 27 , and the tip of the barb 34 is fitted to the outer wall of the filter box 32 .

[0038] In this embodiment, a filter box 32 is provided in the collection barrel 27. Even if algae impurities enter the collection barrel 27, the filter box 32 can be used to further block them, thereby ensuring that the monitoring results of the sampled water body are accurate.

[0039] Moreover, the barbs 34 fit the outer wall of the filter box 32, so as to clean the filter holes of the filter box 32, further preventing the water sample from being affected by algae impurities, improving the sampling efficiency, and ensuring the sampling quality.

[0040] In the present invention, a set of sampling components for monitoring water conservancy and hydropower projects is provided. The sampling components are slidably arranged on one side of a fixing frame 1. After the equipment is fixed by using a foot 2, the height of the sampling components is adjusted according to the environment of the monitoring site to prepare for sampling monitoring. Start the motor 7, loosen the traction rope 9, and the collection bucket 27 sinks in the water body by its own weight. In order to ensure the stability of the traction direction of the traction rope 9, a support arm 14 is provided on one side of the bracket 5. By providing a reinforcing rib plate 16, the traction rope 9 and the collection bucket 27 at one end of the traction rope 9 are ensured to sink stably; When the traction rope 9 is pulled down by the collecting barrel 27, the push plate 21 pushes the weight material into the telescopic tube and then into the weight box 28, which increases the deadweight of the collecting barrel 27, so that the collecting barrel 27 can sink to the water depth required for monitoring, without the need to tie and release the traction rope 9 multiple times to adjust the depth position. According to the sinking to the corresponding depth position of the weight material, the electromagnetic valve in the sampling port 31 is controlled to open and close, and the sampling is completed. Then, the motor 7 is started to pull the collecting barrel 27 up. The outer tube 38 and the inner tube 39 are arranged to slide in sequence to ensure that during the sinking process of the counterweight box 28, the telescopic tube can not only transport the counterweight material, but also change its length following the rise and fall of the counterweight box 28; A filter box 32 is provided in the collection barrel 27. Even if algae impurities enter the collection barrel 27, the filter box 32 can be used to further block them, thereby ensuring that the monitoring results of the sampled water body are accurate.
