Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and hydropower project sampling, and particularly to a multifunctional monitoring device for water conservancy and hydropower projects and its usage method. Background Technique

[0002] Water conservancy projects are the general term for various engineering constructions built to control, utilize, and protect surface and underground water resources and the environment. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water volume to meet the needs of people's lives and production for water resources. To ensure water quality safety, the water conservancy industry often needs to sample and analyze water samples.

[0003] There are various types of sampling devices. Due to different sampling objects, different water intake devices have emerged, such as water buckets used for collecting water samples on the water surface and Nansen water samplers commonly used for collecting water samples at various depths below the water surface. In the prior art, for different depth positions on the water surface, marks are usually set at corresponding positions on the suspension rope. The sampling device is sunk into the water until the mark coincides with the water surface for sampling. The mark position is controlled by manually retracting and releasing the suspension rope, and observing the coincidence state between the mark position and the water surface, with poor accuracy. And since each tying can only complete one sampling, for the same detection water area, when sampling at different depth points, multiple tying processes are required, resulting in low sampling efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art of poor accuracy and low sampling efficiency. Since each tying can only complete one sampling, for the same detection water area, multiple tying processes are required when sampling at different depth points.

A moving block is fixedly installed on the surface of the linking rod. A sliding block is connected to the bottom of the moving block. A sliding groove is formed in the support arm, and the sliding block is matched with the sliding groove.

[0011] In order to enable the telescopic pipe to both convey the counterweight material and change its length following the lifting and lowering of the counterweight box, further, the telescopic pipe includes an outer pipe and an inner pipe that are hermetically and slidably sleeved. A limiting groove is formed in the outer pipe. Convex platforms are arranged at both ends of the inner pipe, and the convex platforms are slidably connected in the limiting groove.

[0036] It further includes: a sampling assembly slidably arranged on one side of the fixing frame 1. The sampling assembly includes a towing rope 9 and a collecting bucket 27 connected to one end of the towing rope 9. A sampling port 31 with a solenoid valve is communicated with the top of the collecting bucket 27. A bracket 5 is fixedly installed on one side of the moving plate 4. A winding roller 8 is rotatably connected in the bracket 5 through a winding shaft 6. One end of the winding shaft 6 is drivingly connected to a motor 7.

To ensure the stable towing direction of the towing rope 9, a support arm 14 is provided on one side of the bracket 5. By setting the reinforcing rib plate 16, the stable sinking of the towing rope 9 and the collecting bucket 27 at one end of the towing rope 9 is ensured.

[0039] A counterweight assembly symmetrically arranged on both sides of the sampling assembly. When the self-weight of the counterweight assembly changes, the sampling assembly stays at different depth positions in the water body;

[0040] The counterweight assembly includes two sets of storage pipes 17 for filling counterweight materials and telescopic pipes connected to one end of the storage pipes 17 through elbow pipes 23. The storage pipes 17 are arranged on one side of the support arm 14 through fixed support plates 19 and fixed ear plates 20. The bottom end of the telescopic pipe is connected to a counterweight box 28. A support plate 35 is slidably installed in the counterweight box 28. A push plate 21 is slidably connected in the storage pipe 17. One side of the push plate 21 is fixedly connected to a pull rope 22. One end of the pull rope 22 away from the push plate 21 is fixedly connected to the support plate 35. A support rod 25 is rotatably installed in the elbow pipe 23. A transition pulley 24 is connected to the surface of the support rod 25. The pull rope 22 is fitted and wound around the annular depression of the transition pulley 24.

[0041] In this embodiment, counterweight boxes 28 are connected to both sides of the collection bucket 27. The telescopic pipes are connected to the upper part of the counterweight boxes 28. The top ends of the telescopic pipes are connected to the storage pipes 17. Counterweight materials are placed in the storage pipes 17. During the process of the traction rope 9 being pulled down by the collection bucket 27, the push plate 21 pushes the counterweight materials into the telescopic pipes and then into the counterweight boxes 28, increasing the self-weight of the collection bucket 27, enabling the collection bucket 27 to sink to the water depth required for monitoring. There is no need to repeatedly tie the traction rope 9 to adjust the depth position. According to the dropping of the counterweight materials, it sinks to the corresponding depth position, controls the opening and closing of the solenoid valve in the sampling port 31. After sampling is completed, start the motor 7 and pull the collection bucket 27 up.

[0042] It should be noted that since the support plate 35 is arranged in the counterweight box 28, when the motor 7 drives the traction rope 9 to wind up, the traction rope 9 drives the linkage rod 11 to pull the push plate 21 back to its original position, pulling the support plate 35 to squeeze the counterweight materials back into the storage pipes 17 through the telescopic pipes of the counterweight box 28, and the counterweight materials can be reused.

[0043] Traction blocks 10 are fixedly installed on the surface of the traction rope 9. Linkage rods 11 are symmetrically arranged on both sides of the traction blocks 10. One end of the linkage rod 11 extends into the storage pipe 17 and is fixedly connected to the push plate 21. Through slots that are slidably matched with the linkage rod 11 are opened on the storage pipe 17. Bellows plates 18 are fixedly installed in the through slots. Moving blocks 12 are fixedly installed on the surface of the linkage rod 11. Sliders 13 are connected to the bottom of the moving blocks 12. Sliding grooves 15 are opened in the support arm 14, and the sliders 13 are matched with the sliding grooves 15.

[0044] In this embodiment, traction blocks 10 are arranged on the surface of the traction rope 9. Linkage rods 11 are connected to both sides of the traction blocks 10. The linkage rods 11 are connected to the push plate 21 of the storage pipe 17. Following the movement, it promotes the dropping of the counterweight materials into the counterweight box 28. The linkage rods 11 penetrate through the storage pipe 17 and are connected to the push plate 21. Therefore, bellows plates 18 are arranged in the through slots of the storage pipe 17 to ensure the normal movement of the linkage rods 11 while preventing the leakage of the internal counterweight materials.

[0045] The telescopic tube includes 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 .

[0046] 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.

[0047] 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 .

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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 .

[0052] 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.

[0053] 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.

[0054] In the present invention, a set of sampling components for water conservancy and hydropower project monitoring is provided. The sampling components are slidably arranged on one side of the fixing frame 1. After fixing the equipment with the anchor feet 2, the height of the sampling components is adjusted according to the environment of the monitoring site to prepare for sampling and monitoring.

[0055] Start the motor 7 and loosen the towing rope 9. The collection bucket 27 sinks in the water body by its own weight. To ensure the stable towing direction of the towing rope 9, a support arm 14 is arranged on one side of the bracket 5. By setting the reinforcing rib plates 16, the stable sinking of the towing rope 9 and the collection bucket 27 at one end of the towing rope 9 is ensured.

[0056] During the process of the towing rope 9 sinking under the traction of the collection bucket 27, the pushing plate 21 pushes the counterweight material into the telescopic tube and then into the counterweight box 28, increasing the self-weight of the collection bucket 27, so that the collection bucket 27 can sink to the water depth required for monitoring. There is no need to tie the towing rope 9 multiple times to adjust the depth position. According to the dropping of the counterweight material, it sinks to the corresponding depth position. Control the opening and closing of the solenoid valve in the sampling port 31. After sampling is completed, start the motor 7 to tow the collection bucket 27 up.

[0057] The outer tube 38 and the inner tube 39 are sleeved and slidably arranged 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 lifting and lowering of the counterweight box 28.

[0058] A filter box 32 is arranged in the collection bucket 27. Even if algae impurities enter the collection bucket 27, the filter box 32 can further block them to ensure the accuracy of the water body monitoring results of the sampling.

[0059] Moreover, the barbs 34 are attached to the outer wall of the filter box 32, which can clean the filter holes of the filter box 32, further avoiding the influence of algae impurities on the water sample, improving the sampling efficiency, and ensuring the sampling quality.
