Description

Technical Field

[0001] This utility model relates to the field of monitoring and sampling technology, and in particular to an environmental monitoring and sampling device. Background Technology

[0002] Water pollution refers to the contamination of water bodies. If pollutants are discharged directly or indirectly into water without being treated to remove harmful substances, it will cause water pollution and environmental degradation. Therefore, the analysis and detection of water pollution is crucial. This is inseparable from the process of sampling polluted water bodies. Data obtained from water samples can be used to classify the pollution level of the entire watershed and take corresponding measures to reduce pollution.

[0003] A search revealed that Chinese Patent Publication No. CN218121499U discloses an environmental monitoring sampling device, including a water suction pipe. The water suction pipe is a hollow circular tube with a circular opening at its upper end. A blocking block is engaged at the upper opening of the water suction pipe, and a threaded sleeve is fixedly connected to the upper end of the blocking block. A movable hole is opened at the upper end of the threaded sleeve, and a movable column is movably installed inside the movable hole. The device moves the movable column and piston block via a connecting handle. When the piston block moves inside the water suction pipe, it generates suction, and water enters from inside the first connecting block. The water tank is obstructed by the first and second blocking blocks and becomes entangled on them. Large stones are blocked by a filter screen to prevent clogging. The second connecting block allows for the movement of the blocking block, filter screen, and the first and second blocking blocks, facilitating disassembly and cleaning and enhancing the practicality of the device.

[0004] However, in the existing technology, when sampling water, it is necessary to sample at different depths. However, in the existing device, when sampling water at different depths, the sampling tube needs to be placed at different depths, which is repetitive, complicated and inconvenient. A solution is proposed to solve the problems mentioned in the background technology. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an environmental monitoring sampling device, which aims to improve the problem that when sampling water bodies, it is necessary to sample at different depths. However, in existing devices, sampling tubes need to be placed at different depths when sampling water bodies at different depths, which is a repetitive, complicated and inconvenient sampling process.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: It includes a first sampling rod, with a second sampling rod slidably connected inside the first sampling rod. First mounting brackets are fixedly connected to both sides of the first sampling rod, and second mounting brackets are fixedly connected to both sides of the second sampling rod. A collection container is slidably connected to one side of each of the two first mounting brackets and one side of each of the two second mounting brackets. A sealing cap is snapped onto the upper end of the collection container. Fixing brackets are fixedly connected to both sides of the upper end of the collection container. Springs are fixedly connected to one side of each of the two fixing brackets. One end of each spring is fixedly connected to one side of the upper end of the sealing cap. Both ends of the cover are slidably connected to one side of the two fixed brackets, and the outer surface of the sealing cover is evenly provided with water inlet holes. The upper end of the sealing cover is rotatably connected to a take-up and release wheel. The outer surface of the take-up and release wheel is wound with a pull rope. One end of the pull rope is fixedly connected to a floating ball. One fastening ring is threadedly connected to one side of the outer surface of the take-up and release wheel. Rectangular grooves are provided on one side of the two first mounting brackets and one side of the two second mounting brackets. Limiting rods are fixedly connected to one side of the four collection tanks. The outer surfaces of the four limiting rods are slidably connected to the interior of the four rectangular grooves, and the outer surfaces of the four limiting rods are threadedly connected to the second fastening ring.

[0007] As a further description of the above technical solution: When sampling water, the second fastening ring on the side of the collection tank can be loosened to release the limit rod. The collection tank can then be moved between the first and second mounting frames. Once each collection tank is moved to the required height, the second fastening ring can be tightened. Then, the first fastening ring is rotated, and the release and retraction wheels are rotated according to the height of each collection tank to release an appropriate length of pull rope. This ensures that the pull rope remains taut after the collection tank is submerged and is about to reach the sampling depth, and that the floating ball on the pull rope remains floating on the water surface. The completed device can then be vertically lowered into the water. Because its floating ball always floats on the water surface, it is continuously connected to the pull rope. When each collection tank is about to reach the sampling depth, the floating ball will taut the pull rope due to the buoyancy of the water. When the collection tank reaches the sampling depth, the pull rope will pull the sealing cover upward under the action of buoyancy. The upward movement of the sealing cover will compress the springs on both sides. After moving upward a certain distance, the water inlet hole on the side of the sealing cover will leak out. At this time, water can enter the collection tank through the water inlet hole. After the collection tank is full, the device can be pulled out of the water. At this time, the pull rope will release the pull of the sealing cover, and the compressed springs on both sides will return to their original position and push the sealing cover to reseal the top of the collection tank.

[0008] Preferably, both sides of the first sampling rod are provided with movable grooves, and the interior of the two movable grooves are slidably connected to the outer surfaces of the two second mounting brackets, respectively.

[0009] As a further description of the above technical solution: the No. 2 mounting bracket can move within the movable slot when the No. 2 sampling rod moves.

[0010] Preferably, the first sampling rod has sliding grooves on both sides inside, and the second sampling rod has sliding blocks fixedly connected to both sides.

[0011] As a further description of the above technical solution: the sliding block can move within the sliding groove when the second sampling rod moves.

[0012] Preferably, the outer surfaces of the two sliding blocks are slidably connected to the interior of the two sliding grooves, and the internal thread of the second sampling rod is connected to a lead screw.

[0013] As a further description of the above technical solution: the movement of the second sampling rod, which is threadedly connected to it, can be controlled by rotating the lead screw.

[0014] Preferably, the upper part of the outer surface of the lead screw is rotatably connected to the upper end of the first sampling rod, and a knob is fixedly connected to the upper end of the lead screw.

[0015] As a further description of the above technical solution: the knob makes it more convenient to rotate the lead screw.

[0016] Preferably, a support frame is fixedly connected to the upper end of the first sampling rod, and a connecting plate is fixedly connected to the upper end of the support frame.

[0017] As a further description of the above technical solution: the support frame can be used to fix the connecting plate and the handle.

[0018] Preferably, a handle is fixedly connected to the upper end of the connecting plate, and an anti-slip sleeve is fitted onto the outer surface of the handle.

[0019] As a further description of the above technical solution: the anti-slip sleeve can be used to increase the friction on the outside of the handle, making the device more stable when gripping.

[0020] Preferably, a spirit level is fixedly connected to the upper end of the connecting plate, and reinforcing ribs are fixedly connected to both sides of the lower end of the connecting plate.

[0021] As a further description of the above technical solution: the level allows the device to be observed in real time whether it is in a vertical state when it is submerged in water.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. In this utility model, when sampling water, the second fastening ring on the side of the collection tank can be loosened first to release the limit rod. Then, the collection tanks can be moved on the first and second mounting frames respectively. After each collection tank is moved to the required height, the second fastening ring can be tightened. Then, the first fastening ring is rotated, and the release wheel is rotated according to the height of each collection tank to release an appropriate length of pull rope. This ensures that the pull rope remains taut after the collection tank is submerged and is about to reach the sampling depth, and the floating ball on the pull rope remains floating on the water surface. The completed device can then be vertically lowered into the water. Because the floating ball remains constantly floating on the water surface, it will continuously connect to the pull rope, allowing the collection tanks to move freely. As the device approaches the sampling depth, the floating ball tauts the pull rope due to buoyancy. When the collection tank reaches the sampling depth, the pull rope, under the influence of buoyancy, pulls the sealing cap upwards. The upward movement of the sealing cap compresses the springs on both sides. After moving upwards a certain distance, the water inlet hole on the side of the sealing cap leaks out, allowing water to enter the collection tank. Once the collection tank is full, the device can be pulled out of the water. At this point, the pull rope releases the tension on the sealing cap, and the compressed springs on both sides reset, pushing the sealing cap to reseal the top of the collection tank. This method allows the device to perform stratified sampling at different depths of water without repeatedly using the sampling device for stratified sampling, significantly reducing the workload of stratified water sampling and improving the efficiency of the sampling work.

[0024] 2. In this utility model, when the water body to be sampled is deep and the device length is insufficient, the screw can be rotated by rotating the knob. The rotating screw will control the second sampling rod, which is threaded to it, to move inside the first sampling rod. As the second sampling rod continues to move, the length of the device can be significantly increased. At this time, sampling work can be carried out in deeper water bodies. This method allows the device to adjust its length in a timely manner when facing different sampling needs, improving the applicability of the device and making it more convenient to use.

[0032] 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.

[0033] Reference Figures 1 to 5As shown, one embodiment of this utility model includes a first sampling rod 1, with a second sampling rod 26 slidably connected inside the first sampling rod 1. First mounting brackets 3 are fixedly connected to both sides of the first sampling rod 1, and second mounting brackets 2 are fixedly connected to both sides of the second sampling rod 26. A collection tank 4 is slidably connected to one side of each of the two first mounting brackets 3 and one side of each of the two second mounting brackets 2. A sealing cap 17 is snapped onto the upper end of the collection tank 4. Fixing brackets 15 are fixedly connected to both sides of the upper end of the collection tank 4. Springs 20 are fixedly connected to one side of each of the two fixing brackets 15. One end of each spring 20 is fixedly connected to one side of the upper end of the sealing cap 17. The two ends of the sealing cap 17 are respectively... The sealing cover 17 is slidably connected to one side of the two fixed brackets 15. Water inlet holes 21 are evenly opened on the outer surface of the sealing cover 17. The upper end of the sealing cover 17 is rotatably connected to the take-up and release wheel 19. The outer surface of the take-up and release wheel 19 is wound with a pull rope 16. One end of the pull rope 16 is fixedly connected to a floating ball 5. One fastening ring 18 is threadedly connected to one side of the outer surface of the take-up and release wheel 19. Rectangular grooves 12 are opened on one side of the two first mounting brackets 3 and one side of the two second mounting brackets 2. Limiting rods 13 are fixedly connected to one side of the four collection tanks 4. The outer surfaces of the four limiting rods 13 are slidably connected to the interior of the four rectangular grooves 12 respectively. The outer surfaces of the four limiting rods 13 are threadedly connected to the second fastening ring 14.

[0034] In this embodiment, when sampling the water, the second fastening ring 14 on the side of the collection tank 4 can be loosened to release the limit rod 13. Then, the collection tank 4 can be moved on the first mounting bracket 3 and the second mounting bracket 2 respectively. After each collection tank 4 is moved to the required height, the second fastening ring 14 can be tightened. Then, the first fastening ring 18 is rotated, and the release wheel 19 is rotated according to the height of each collection tank 4 to release an appropriate length of pull rope 16. This ensures that the pull rope 16 remains taut after the collection tank 4 is submerged and is about to reach the sampling depth, and the floating ball 5 on the pull rope 16 remains floating on the water surface. The completed device can then be vertically lowered into the water. Since the floating ball 5 remains floating on the water surface, it will continuously connect to the pull rope 16. When the sampling depth is reached, the floating ball 5 will taut the pulling rope 16 due to the buoyancy of the water. When the collection tank 4 reaches the sampling depth, the pulling rope 16 will pull the sealing cover 17 upward under the action of buoyancy. The upward movement of the sealing cover 17 will compress the springs 20 on both sides. After moving upward a certain distance, the water inlet hole 21 on the side of the sealing cover 17 will leak out. At this time, water can enter the collection tank 4 through the water inlet hole 21. After the collection tank 4 is full, the device can be pulled out of the water. At this time, the pulling rope 16 will release the pull of the sealing cover 17, and the compressed springs 20 on both sides will reset and push the sealing cover 17 to reseal the top of the collection tank 4. In this way, when the device performs stratified sampling at different depths of the water body, it is not necessary to repeatedly use the sampling device for stratified sampling, which greatly reduces the workload of water stratified sampling and improves the efficiency of sampling work.

[0035] Example 2, as Figure 1 , Figure 4 and Figure 5 As shown, the first sampling rod 1 has movable grooves 23 on both sides. The interior of the two movable grooves 23 is slidably connected to the outer surfaces of the two second mounting brackets 2. The interior of the first sampling rod 1 has sliding grooves 28 on both sides. The two sides of the second sampling rod 26 are fixedly connected to sliding blocks 27. The outer surfaces of the two sliding blocks 27 are slidably connected to the interior of the two sliding grooves 28. The interior of the second sampling rod 26 is threaded with a lead screw 25. The upper part of the outer surface of the lead screw 25 is rotatably connected to the upper end of the first sampling rod 1. The upper end of the lead screw 25 is fixedly connected to a knob 6. The upper end of the first sampling rod 1 is fixedly connected to a support frame 11. The upper end of the support frame 11 is fixedly connected to a connecting plate 7. The upper end of the connecting plate 7 is fixedly connected to a handle 8. The outer surface of the handle 8 is fitted with an anti-slip sleeve 9. The upper end of the connecting plate 7 is fixedly connected to a level 10. The lower end of the connecting plate 7 has reinforcing ribs 22 fixedly connected to both sides.

[0036] In this embodiment, when the water body to be sampled is deep and the device length is insufficient, the knob 6 can be rotated to drive the lead screw 25 to rotate. The rotating lead screw 25 will control the second sampling rod 26, which is threadedly connected to it, to move inside the first sampling rod 1. As the second sampling rod 26 continues to move, the length of the device can be significantly increased. At this time, sampling work can be carried out in deeper water bodies. This method allows the device to adjust its length in a timely manner when facing different sampling needs, improving the applicability of the device and making it more convenient to use.

[0037] Working principle: When sampling water, first loosen the second fastening ring 14 on the side of the collection tank 4 to release the limit rod 13. Then, pull the collection tank 4 to move on the first mounting bracket 3 and the second mounting bracket 2 respectively. After moving each collection tank 4 to the required height, tighten the second fastening ring 14. Then rotate the first fastening ring 18, and rotate the take-up and release wheel 19 according to the height of each collection tank 4 to release the pull rope 16 of an appropriate length. After the collection tank 4 is submerged in water and is about to reach the sampling depth, the pull rope 16 can be taut. The device is positioned such that the floating ball 5 on the pull rope 16 remains constantly floating on the water surface. Then, holding the handle 8, the device is vertically lowered into the water, and the level 10 is observed to ensure the device is vertical. Since the floating ball 5 remains constantly floating on the water surface, it is continuously connected to the pull rope 16. As each collection tank 4 approaches the sampling depth, the floating ball 5 tauts the pull rope 16 due to buoyancy. When the collection tank 4 reaches the sampling depth, the pull rope 16, under the influence of buoyancy, pulls the sealing cap 17 upwards. The springs 20 on both sides will be compressed, and after moving upwards a certain distance, the water inlet 21 on the side of the sealing cover 17 will leak out. At this time, water can enter the collection tank 4 through the water inlet 21. After the collection tank 4 is full, the device can be pulled out of the water. At this time, the pulling rope 16 will release the pull of the sealing cover 17, and the compressed springs 20 on both sides will return to their original positions and push the sealing cover 17 to reseal the top of the collection tank 4. In this way, when the device performs stratified sampling of water at different depths, it is not necessary to repeatedly use the sampling device for stratified sampling, which greatly reduces the cost of stratified water sampling. The increased workload improves sampling efficiency. When the water body to be sampled is deep and the device length is insufficient, the knob 6 can be rotated to drive the lead screw 25 to rotate. The rotating lead screw 25 controls the movement of the second sampling rod 26, which is threaded to it, inside the first sampling rod 1. As the second sampling rod 26 continues to move, the length of the device can be significantly increased. At this time, sampling work can be carried out in deeper water bodies. This method allows the length of the device to be adjusted in a timely manner when facing different sampling needs, improving the applicability of the device and making it more convenient to use.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
