Description

Technical Field

[0001] This utility model relates to the field of environmental testing tools, and in particular to a pollution sampling device. Background Technology

[0002] Polluted water sampling refers to the process of extracting water samples from polluted water bodies according to prescribed methods and a certain proportion. By testing and analyzing the extracted water samples, the degree of water pollution, the types and contents of pollutants, and other relevant water quality parameters can be determined. This information guides production activities and enables the implementation of relevant measures to reduce water pollution.

[0003] Existing pollution sampling devices for water quality testing involve drawing water samples into a sampling container, but a single sampling operation can only collect water samples from a fixed range. When it is necessary to collect water samples from different depths, the sampling work needs to be repeated, resulting in low collection efficiency. To solve the above problems, we propose a pollution sampling device. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing pollution sampling devices for water quality testing cannot collect water samples at different depths in a single sampling operation, and to propose a pollution sampling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A contamination sampling device includes a vertical rod with multiple support plates arranged in a circular array fixedly installed at different heights on the vertical rod. A cylindrical body is fixedly installed at the end of each support plate, and an electrically operated telescopic rod is installed inside each cylindrical body. The electrically operated telescopic rod is fixedly installed on the vertical rod, and a piston is fixedly installed at the output end of the electrically operated telescopic rod. The piston is slidably disposed inside the cylindrical body. A suction nozzle is connected to and fixedly installed at one end of the cylindrical body. Multiple movable blocks arranged in a circular array pass through the suction nozzle. Each movable block has a cutting edge at one end inside the suction nozzle. Elastic elements are fixedly connected to both sides of each movable block, and the other end of each elastic element is fixedly connected to the suction nozzle.

[0007] Each vertical pole is fixedly equipped with a controller at its upper end, and each electric telescopic pole is electrically connected to the controller, which is used to control the operation of the electric telescopic pole.

[0008] Preferably, the system further includes a movable plate, through which the vertical rod passes, and the movable plate is slidably mounted on the vertical rod. Limiting plates are provided on both the upper and lower sides of the movable plate, and the limiting plates are fixedly connected to the vertical rod.

[0009] Preferably, each end of the cylinder is provided with a drive assembly, which is used to drive the movable block to move, and the movable plate is provided with a linkage assembly, which is used to drive multiple drive assemblies to move.

[0010] Preferably, the drive assembly includes a plurality of rotating shafts rotatably mounted at the ends of the cylinder, each rotating shaft having an eccentric wheel fixedly mounted on it, each rotating shaft having a friction wheel fixedly mounted at its end, and each cylinder having an annular sleeve rotatably mounted at its end. An inner friction ring is fixedly connected to the inner ring of the annular sleeve, the inner friction ring being in contact with the plurality of friction wheels, and an outer friction ring is disposed on and fixedly connected to the annular sleeve.

[0011] Preferably, the linkage component includes multiple friction strips, which are fixedly connected to the movable plate and are in contact with the outer friction ring.

[0012] Preferably, the surface of the vertical rod is provided with an anti-rust coating.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The device uses a controller to operate multiple electrically operated telescopic rods synchronously. These rods move pistons away from the suction nozzle, reducing the air pressure inside the cylinders and drawing water samples through the nozzle. Because the multiple cylinders are distributed at different locations within the water body, samples can be collected from various depths in a single operation. This eliminates the need for multiple deployments or equipment changes, significantly reducing sampling time, making it particularly suitable for scenarios requiring rapid acquisition of multi-depth data.

[0022] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Reference Figure 1-6 A pollution sampling device includes a vertical rod 1. Multiple support plates 4 arranged in a circular array are fixedly installed at different heights on the vertical rod 1. A cylindrical body 5 is fixedly installed at the end of each support plate 4. Each cylindrical body 5 contains an electrically operated telescopic rod 6, which is fixedly installed on the vertical rod 1. A piston 7 is fixedly installed at the output end of the electrically operated telescopic rod 6, and the piston 7 is slidably disposed within the cylindrical body 5. A suction nozzle 8 is connected to and fixedly installed at one end of the cylindrical body 5. Multiple movable blocks 9 arranged in a circular array pass through the suction nozzle 8. Each movable block 9 has a cutting edge 10 at one end within the suction nozzle 8. Elastic elements 11 are fixedly connected to both sides of each movable block 9, and the other end of each elastic element 11 is fixedly connected to the suction nozzle 8. The surface of the vertical rod 1 is coated with an anti-rust coating to improve its corrosion resistance. A controller 12 is fixedly installed at the upper end of each vertical rod 1. The electrically operated telescopic rods 6 are electrically connected to the controller 12, which controls the operation of the electrically operated telescopic rods 6.

[0025] Staff members hold the device and place multiple cylinders 5 of varying heights into the water. Controller 12 controls the operation of electric telescopic rods 6, which work synchronously. The electric telescopic rods 6 move pistons 7 away from the suction nozzle 8, reducing the air pressure inside the cylinders 5 and drawing water samples through the nozzle 8. Because multiple cylinders 5 are distributed at different locations within the water, samples can be collected from different depths. A single operation can sample water at various depths. This eliminates the need for multiple deployments or equipment changes, significantly reducing sampling time, and is particularly suitable for scenarios requiring rapid acquisition of multi-depth data.

[0026] The controller 12 controls the independent electric telescopic rod 6 to work. The electric telescopic rod 6 drives the piston 7 to move toward the suction nozzle 8. The piston 7 can push the water sample in the cylinder 5 out of the suction nozzle 8.

[0027] Based on Example 1, Example 2:

[0028] Reference Figure 2-6 The system also includes a movable plate 2, through which a vertical rod 1 passes. The movable plate 2 is slidably mounted on the vertical rod 1. Limiting plates 3 are provided on both the upper and lower sides of the movable plate 2, and the limiting plates 3 are fixedly connected to the vertical rod 1. A drive assembly is provided at each end of the cylinder 5 to drive the movable block 9 to move. A linkage assembly is provided on the movable plate 2 to drive multiple drive assemblies. The drive assembly includes multiple rotating shafts 13 rotatably mounted at the ends of the cylinder 5. An eccentric wheel 14 is fixedly mounted on each rotating shaft 13, and a friction wheel 15 is fixedly mounted at each end of the rotating shaft 13. An annular sleeve 16 is rotatably mounted at each end of the cylinder 5. An inner friction ring 17 is fixedly connected to the inner ring of the annular sleeve 16, and the inner friction ring 17 contacts the multiple friction wheels 15. An outer friction ring 18 is fitted and fixedly connected to the outer ring of the annular sleeve 16. The linkage assembly includes multiple friction strips 19, which are fixedly connected to the movable plate 2 and contact the outer friction ring 18.

[0029] When impurities such as aquatic plants and algae are present in the water, they are prone to clogging when passing through the suction nozzle 8. Therefore, when sampling water bodies of this type, the movable plate 2 is moved up and down repeatedly. The limiting plate 3 can limit the movable plate 2. The friction strip 19 on the movable plate 2 drives the outer friction ring 18 to rotate through friction. The outer friction ring 18, the annular sleeve 16, and the inner friction ring 17 rotate synchronously. The inner friction ring 17 drives multiple friction wheels 15 to rotate. The friction wheels 15, the rotating shaft 13, and the eccentric wheel 14 rotate synchronously. The eccentric wheel 14 rotates eccentrically around the rotating shaft 13. The eccentric wheel 14 squeezes the movable block 9. The cutting blade 10 on the movable block 9 moves and cuts the impurities, which can prevent the suction nozzle 8 from being blocked by impurities. The elastic element 11 can drive the movable block 9 and the cutting blade 10 to reset.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
