Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a water sample collector for ecological and environmental water sample testing. Background Technology

[0002] Construction projects may pollute surrounding water bodies during the construction process. In order to assess the impact of construction on the ecological environment and ensure compliance with environmental protection requirements, it is necessary to collect water samples from the ecological environment, promptly identify potential pollution risks, and take preventive measures to reduce harm to the environment and public health.

[0003] Sampling devices are required when collecting water samples. Some existing sampling devices collect water samples by setting up water pumps and pumping pipes. However, the purchase and maintenance costs of water pumps and their supporting equipment (such as pipes, power supplies, and controllers) are relatively high, which is not conducive to widespread use. The most common method is still the traditional sampling bucket with an opening. When sampling, the sampling bucket is tilted in the water so that the opening of the sampling bucket is below the water surface, allowing water to enter the sampling bucket to complete the water sample collection. The sampling bucket needs to be tilted constantly during use, which is not only inconvenient to operate, but also only convenient for collecting samples from the upper layer of water. Based on this, a water sampler for ecological and environmental water sample testing is proposed. Utility Model Content

[0004] This utility model provides a water sampler for ecological environment testing, which solves the problem mentioned in the above technical background that the existing sampling buckets need to be tilted constantly during use, which is not only inconvenient to operate, but also only convenient for collecting water samples from the upper layer.

[0005] A water sampler for ecological and environmental testing includes a barrel body. A sampling tube is fixedly installed in the middle of the bottom of the barrel body. A counterweight is installed inside the barrel body. A sealing plug is fixedly installed at the bottom of the counterweight. The sealing plug seals the sampling tube under the gravity of the counterweight. A vertical rod is fixedly installed in the middle of the top of the barrel body. A horizontal plate is fixedly installed at the top of the vertical rod. A handle is fixedly installed at the top of the horizontal plate. A pull rope is fixedly installed at the top of the counterweight. The top of the pull rope passes through the barrel body, the vertical rod, and the horizontal plate in sequence and is fixedly provided with a pull ring.

[0006] Preferably, the inner walls on both sides of the barrel are symmetrically provided with limiting grooves, and limiting blocks are slidably connected in the limiting grooves. A connecting rod is fixedly provided on the side wall of the limiting block, and the connecting rod is fixedly connected to the side wall of the counterweight block.

[0007] Preferably, a first magnetic block is fixedly provided on the bottom inner wall of the barrel, and a second magnetic block is fixedly provided on the bottom of the counterweight block. The first magnetic block and the second magnetic block are magnetically attracted to each other and their positions correspond to each other.

[0008] Preferably, a water collection cover is detachably connected to the bottom of the sampling tube, and a filter screen is fixedly installed at the bottom of the water collection cover.

[0009] Preferably, the vertical rod is configured as a fixed rod and an adjusting rod, the adjusting rod is slidably connected inside the fixed rod, and a fixing bolt for fixing the adjusting rod is provided on one side below the fixed rod.

[0010] Preferably, two mounting plates are fixedly provided on one side of the horizontal plate, and a winding roller is rotatably connected between the two mounting plates. The top of the pull rope passes through the barrel, the fixed rod, the adjusting rod and the side wall of the horizontal plate in sequence and is fixedly connected to the winding roller. One end of the winding roller passes through the mounting plate and is fixedly connected to a rotating handle.

[0011] The beneficial effects of this utility model are:

[0012] (1) This utility model involves immersing the bucket in water, pulling the pull ring upwards to move the pull rope and the counterweight upwards, causing the sealing plug at the bottom of the counterweight to detach from the sampling tube, thus releasing the seal on the sampling tube. Water enters the bucket under external pressure for sampling. After sampling is completed, the pull rope is released by hand, and the counterweight moves the sealing plug downwards under its own weight to seal the sampling tube, thus completing the sampling. This method is not only convenient to operate, but also has a simple structure and low usage and maintenance costs.

[0013] (2) This utility model adjusts the position of the adjusting rod in the fixed rod and fixes it with fixing bolts to adjust the overall length of the vertical rod. While adjusting the length of the vertical rod, the winding roller is rotated to adjust the length of the pulling rope synchronously so that the two are compatible, so as to adjust the depth of the bucket in the water when sampling and collect water samples at different depths.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] like Figure 1-3 As shown, a water sampler for ecological environment testing includes a barrel 1. A sampling tube 2 is fixedly installed in the middle of the bottom of the barrel 1. A counterweight 3 is installed inside the barrel 1. A sealing plug 4 is fixedly installed at the bottom of the counterweight 3. The sealing plug 4 has a conical structure that is wider at the top and narrower at the bottom. The sealing plug 4 is made of rubber. The elasticity of the rubber can improve the sealing performance of the sampling tube 2. The sealing plug 4 seals the sampling tube 2 under the gravity of the counterweight 3. The gravity of the counterweight 3 is greater than the buoyancy it experiences in the water. A vertical rod 5 is fixedly installed in the middle of the top of the barrel 1. A horizontal plate 6 is fixedly installed at the top of the vertical rod 5. A handle 7 is fixedly installed at the top of the horizontal plate 6. A pull rope 8 is fixedly installed at the top of the counterweight 3. The top of the pull rope 8 passes through the barrel 1, the vertical rod 5, and the horizontal plate 6 in sequence and is fixedly connected to a pull ring. A through groove is opened in the top of the barrel 1, the inside of the vertical rod 5, and the middle of the horizontal plate 6 for the pull rope 8 to pass through. The pull rope 8 passes through the through groove and is fixedly connected to the pull ring.

[0023] Holding handle 7, immerse bucket 1 into the water to be sampled, so that the top of bucket 1 is submerged. Pull the pull ring upwards to move the pull rope 8 upwards, causing the counterweight 3 to move upwards. This causes the sealing plug 4 at the bottom of the counterweight 3 to detach from the sampling tube 2, releasing the seal on the sampling tube 2. Water enters bucket 1 under external pressure for sampling. After sampling is completed, release the pull rope 8. The counterweight 3, under its own weight, moves the sealing plug 4 downwards to seal the sampling tube 2, completing the sampling.

[0024] The inner walls of both sides of the barrel 1 are symmetrically provided with limiting grooves 9. Limiting blocks 10 are slidably connected in the limiting grooves 9. A connecting rod 11 is fixedly provided on the side wall of the limiting block 10. The connecting rod 11 is fixedly connected to the side wall of the counterweight 3. By setting the limiting grooves 9, limiting blocks 10 and connecting rods 11, the movement trajectory of the counterweight 3 is limited without affecting the movement of the counterweight 3. This ensures that when the counterweight 3 moves up and down with the pull rope 8, the sealing plug 4 at the bottom of the counterweight 3 always corresponds to the position of the sampling tube 2, avoiding the problem of poor sealing caused by the deviation of the counterweight 3.

[0025] A first magnetic block 12 is fixedly provided on the bottom inner wall of the barrel 1, and a second magnetic block 13 is fixedly provided on the bottom of the counterweight 3. The first magnetic block 12 and the second magnetic block 13 are magnetically attracted to each other and are positioned correspondingly. When the counterweight 3 moves down to the bottom, the first magnetic block 12 and the second magnetic block 13 are attracted to each other under the action of magnetic force, which improves the stability of the counterweight 3 at the bottom, and thus improves the stability of the sealing plug 4 at the bottom of the counterweight 3 when sealing the sampling tube 2.

[0026] The bottom of the sampling tube 2 is detachably connected to a water collection cover 14. A filter screen 15 is fixedly installed at the bottom of the water collection cover 14. The outer wall of the part of the bottom of the sampling tube 2 that protrudes from the barrel is provided with an external thread groove. The inside of the tube above the water collection cover 14 is provided with an internal thread groove. The internal thread groove and the external thread groove are adapted to each other. The water collection cover 14 is threadedly connected to the bottom of the sampling tube 2 through the cooperation between the internal thread groove and the external thread groove. This allows impurities in the water to be filtered through the filter screen 15 at the bottom of the water collection cover 2 during sampling, and it is also easy to disassemble and clean the filter screen 15.

[0027] Example 2

[0028] To achieve water sampling at different depths, the length of the vertical rod 5 needs to be adjusted. Simultaneously, the length of the pulling rope 8 needs to be adapted accordingly. Therefore, this embodiment further improves upon Embodiment 1 in this regard. The improvements are as follows:

[0029] The vertical rod 5 is configured as a fixed rod 501 and an adjusting rod 502. The fixed rod 501 is fixedly connected to the bottom middle of the horizontal plate 6, and the adjusting rod 502 is slidably connected inside the fixed rod 501. The bottom of the adjusting rod 502 is fixedly connected to the barrel 1. A fixing bolt 503 for fixing the adjusting rod 502 is provided on one side below the fixed rod 501. A receiving cavity is opened inside the fixed rod 501. Through grooves for the pulling rope 8 to pass through are opened inside the adjusting rod 502, the top of the fixed rod 501, and the horizontal plate 6. By adjusting the position of the adjusting rod 502 in the fixed rod 501 and fixing it with the fixing bolt 503, the overall length of the vertical rod 5 can be adjusted to adjust the depth of the barrel 1 in the water and collect water samples at different depths.

[0030] Two mounting plates 16 are fixedly provided on one side of the horizontal plate 6. A winding roller 17 is rotatably connected between the two mounting plates 16. The top of the pull rope 8 passes through the barrel 1, the fixed rod 501, the adjusting rod 502 and the side wall of the horizontal plate 6 in sequence and is fixedly connected to the winding roller 17. One end of the winding roller 17 passes through the mounting plate 16 and is fixedly connected to a rotating handle.

[0031] By setting up the take-up roller 17, it is convenient to rotate the take-up roller 17 to pull the counterweight 3 upward by the pull rope 8, and it is also convenient to regularly store the excess pull rope 8. The pull rope 8 can be wound up and unwound according to the length of the vertical rod 5, and the neatness of the pull rope 8 can be guaranteed.

[0032] During use, the position of the adjusting rod 502 in the fixed rod 501 is adjusted according to the sampling depth and fixed by the fixing bolt 503. At the same time, the winding roller 17 is rotated so that the length of the pulling rope 8 is adapted to it, without affecting the sealing of the sampling tube 2 by the sealing plug 4 at the bottom of the counterweight 3. The sampling depth of the bucket 1 is submerged in water. The winding roller 17 is rotated to drive the pulling rope 8 to move the counterweight 3 upward, so that the sealing plug 4 at the bottom of the counterweight 3 is disengaged from the sampling tube 2, releasing the seal on the sampling tube 2. Water enters the bucket 1 under external pressure for sampling. After sampling is completed, the counterweight 3 moves the sealing plug 4 downward under its own weight to seal the sampling tube 2, completing the sampling.

[0033] It should be noted that, for the present invention as fully described, there may be various variations and modifications, and it is not limited to the specific embodiments described above. In summary, the scope of protection of this utility model should include those variations, substitutions, and modifications that are obvious to those skilled in the art, and the appended claims shall prevail.
