Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and more specifically, to a sampling device for water conservancy engineering construction. Background Technology

[0002] The water conservancy engineering major cultivates senior engineering and technical personnel with comprehensive abilities in surveying, planning, design, construction, scientific research and management, serving the planning, construction and management of water conservancy, hydropower and soil and water conservation fields. With the increasing demand for water quality testing, the existing sampling devices have obvious shortcomings: first, it is difficult to sample from a distance, resulting in insufficient sample representativeness; second, it lacks the function of multi-sample dispensing, affecting the sampling efficiency; and third, it is impossible to sample from multiple sites, so it is necessary to use this method.

[0003] A search revealed that Chinese Patent Publication No. CN215178884U discloses "a sampling device for water conservancy projects, including a base plate, a placement cabinet on the upper surface of the base plate, and a rotating plate on the lower inner surface of the placement cabinet. This sampling device for water conservancy projects, by setting up a motor, a rotating shaft, a sampler, and a pressure sensor, allows water samples to be fed into the sampler through a connecting pipe during sampling. When the amount of water sample inside the sampler reaches a certain level, the pressure sensor senses the weight of the sampler. When the weight reaches a certain level, the motor starts, driving the rotating shaft to rotate, thereby rotating the empty sampler directly below the connecting pipe for the placement of the next water sample. This structure allows for the placement of multiple samples, making it convenient for testing personnel to use and enabling them to collect water samples from multiple sources for testing, thus improving the testing efficiency." However, the following drawbacks still exist:

[0004] The device has several shortcomings in the sampling process. It is equipped with only a single sampling container and delivery pipeline for multiple sampling operations, which can easily lead to cross-contamination of samples due to incomplete cleaning. Secondly, when sampling at different depths, the sampling process needs to be frequently interrupted to clean the equipment, which seriously affects the sampling efficiency. In addition, it has poor adaptability to samples containing impurities and is prone to pipeline blockage. The lack of effective sealing and temperature control devices for sample storage can lead to the loss of volatile components or sample deterioration, ultimately affecting the accuracy of the test data.

[0005] Therefore, we made improvements and proposed a sampling device for water conservancy engineering construction. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] like Figure 1-5 As shown, this embodiment proposes a sampling device for water conservancy engineering construction, including a housing 1, a sampling component 2 at the bottom of the housing 1, and a storage component 3 on one side of the housing 1.

[0034] like Figure 2 and Figure 3As shown, the sampling assembly 2 includes an electric winch 201, a support frame 202, a rope 203, a roller 204, a counterweight 205, a bracket 206, a cap 207, a spring 208, a sampling container 209, a fixing ring 210, and a braided rope 211. The electric winch 201 is located inside the housing 1. Two support frames 202 are fixedly connected to opposite sides of the outer wall of the housing 1. The rope 203 is wound around the outer wall of the electric winch 201. Two rollers 204 are rotatably connected to opposite sides of the outer wall of the housing 1. The counterweight 205... 5. The other end of the rope 203 is fixedly connected to the other end. The four supports 206 are all fixedly connected to the top of the counterweight 205. The four caps 207 are rotatably connected to the bottom of the four supports 206 respectively. One end of each of the multiple springs 208 is fixedly connected to the bottom of the support 206 and the other end is fixedly connected to the top of the cap 207. The four sampling containers 209 are all slidably connected to one side of the counterweight 205. The fixing ring 210 is sleeved on the outer wall of the counterweight 205. One end of each of the four braided ropes 211 is fixedly connected to the top of the cap 207. The housing 1 is moved to the target sampling point and secured to the external support using the support frame 202. The sampling container 209 is then assembled into the counterweight 205 and locked in place using the retaining ring 210. During operation, the electric winch 201 is activated, and the counterweight 205 is slowly lowered into the water via the rope 203. When the sampling device reaches the predetermined depth, the braided rope 211 at the corresponding position is pulled, and the roller 204 provides an upward force to the braided rope 211, thereby pulling the cap 207 upward and causing the spring 208 to contract. This allows the target water sample to flow into the corresponding sampling container 209, effectively preventing cross-contamination between samples from different sampling points. After sampling, the braided rope 211 is released, and the spring 208 rebounds, resetting the cap 207 to prevent non-target samples from entering and ensuring the purity and representativeness of the sample. This not only facilitates sample collection but also improves sampling efficiency and ensures the quality of sample collection.

[0035] like Figure 4As shown, the storage component 3 includes a trolley 301, a folding arm 302, a buckle 303, a storage box 304, a box door 305, a sampling plate 306, a fixing plate 307, and drawers 308. The trolley 301 is disposed on one side of the housing 1. One side of the folding arm 302 is hinged to one side of the housing 1, and the other end is hinged to the top of the trolley 301. Multiple buckles 303 are fixedly connected to one side of the trolley 301. The storage box 304 is fixedly connected to the top of the trolley 301. The box door 305 is hinged to one side of the storage box 304. The sampling plate 306 is slidably connected to the inner wall of the storage box 304. The fixing plate 307 is fixedly connected to the inside of the storage box 304. Three drawers 308 are slidably connected to the top of the fixing plate 307. The housing 1 is fixed to the folding arm 302 on the trolley 301, enabling convenient movement; the storage box 304 and the sampling plate 306 not only significantly improve the efficiency of field sampling, but also stabilize the sampling pot 209 to prevent it from tipping over and ensure the safety and no leakage of samples; multiple buckles 303 can limit one end of the braided rope 211, facilitating sampling operations; the combination of the fixing plate 307 and the drawer 308 provides classified storage space for temporary testing tools and other sampling accessories, realizing the orderly storage and quick access of tools, greatly improving the smoothness and efficiency of field operations.

[0036] like Figure 5 As shown, a storage box 4 is fixedly connected to the top of the trolley 301. Two fixing brackets 5 are fixedly connected to the inner wall of the storage box 4, and a cover plate 6 is slidably connected to the top of the storage box 4. When the housing 1 and the counterweight 205 are not in use, first pull out the cover plate 6 of the storage box 4, then remove the connection between the housing 1 and the counterweight 205, and put them into the storage box 4. Through the fixing brackets 5 set in the box, the housing 1 and the counterweight 205 can be stored independently in separate areas, which not only ensures that the equipment is stored neatly and orderly, but also effectively avoids collisions between components during transportation.

[0037] like Figure 5 As shown, a cable management box 7 is fixedly connected to the top of the trolley 301, and a winding post 8 is fixedly connected to the inner bottom wall of the cable management box 7. A baffle 9 is slidably connected to the top of the cable management box 7. When the sample collection in the current area is completed, the ropes 203 and braided ropes 211 used in the collection work can be quickly wound up through the winding post 8 and neatly stored in the dedicated rope 203 box. This not only ensures that the ropes 203 and braided ropes 211 required for sampling are placed in an orderly manner, but also significantly improves the safety and convenience of the overall movement.

[0038] like Figure 4 As shown, the bottom of the counterweight 205 is threadedly connected to a threaded post 10, and the bottom of the threaded post 10 is fixedly connected to a weight block 11. When the water flow is rapid at the sampling location, the weight block 11 can be fixed to the bottom of the counterweight 205 through the threaded post 10, which facilitates stable sample collection.

[0039] like Figure 4 As shown, a perforated plate 12 is slidably connected to the inner wall of the storage box 304, and the perforated plate 12 is located above the sampling plate 306. The perforated plate 12 built into the storage box 304 provides multiple fixation for the sampling container 209, avoiding liquid sloshing from affecting the testing efficiency. It provides stable support and protection for field sampling in complex terrains such as mountains and mining areas.

[0040] like Figure 4 As shown, a plastic pad 13 is provided on the inner bottom wall of the sampling plate 306, and multiple fixing grooves 14 are provided through the plastic pad 13. The fixing grooves 14 inside the plastic pad 13 can provide limiting support for the bottom of the sampling container 209, so as to prevent the bottoms of multiple sampling containers 209 from colliding and being damaged when the trolley 301 moves on uneven ground.

[0041] Specifically, when using the sampling device for this water conservancy project: When sampling on the lake surface, the device is secured to the external support 206 via the support frame 202. The sampling container 209 is then assembled into the counterweight 205 and locked in place using the fixing ring 210. During operation, the electric winch 201 is activated, and the counterweight 205 is slowly lowered into the water via the rope 203. When the sampling device reaches the predetermined depth, the corresponding braided rope 211 is pulled, and the roller 204 provides an upward force to the braided rope 211, thereby pulling the cap 207 upward, causing the spring 208 to contract, and allowing the target water sample to flow into the corresponding sampling container 209, effectively avoiding cross-contamination between samples from different sampling points. After sampling is completed, the braided rope is released... The braided rope 211 and spring 208 rebound to reset the cap 207, preventing non-target samples from entering and ensuring the purity and representativeness of the samples. The housing 1 is fixed to the folding arm 302 on the trolley 301, enabling convenient movement. The storage box 304 and sampling plate 306 significantly improve field sampling efficiency. The strip-shaped perforated plate 12 and plastic pad 13 can stabilize the sampling container 209, ensuring sample safety and no leakage. Multiple buckles 303 not only allow the braided rope 211 to be quickly positioned and firmly fixed, but also facilitate sampling operations. The drawer 308 inside the storage box 304 provides classified storage space for temporary testing tools and other sampling accessories, enabling orderly storage and quick access to tools, greatly improving the smoothness and efficiency of field operations.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
