Description

Technical Field

[0001] This utility model relates to the field of water quality samplers, and in particular to an anti-clogging self-cleaning device for water quality samplers. Background Technology

[0002] A water sampler is a type of water sampler used for sampling water sources. It is a common anti-clogging and self-cleaning device in existing technologies.

[0003] Existing technologies, such as the utility model patent with publication number CN210442134U, disclose a rapid water sampling and automatic cleaning device. This patent uses a barrel body with fixed blocks on both sides. A handle is movably connected between the two fixed blocks. A float plate is placed on the top of the bottom plate of the barrel body. A water storage tank is fixed on the top of the functional cover. The bottom of the water storage tank is connected to the inlet of a water pump through a guide pipe placed inside the functional cover. The outlet of the water pump is connected to the inside of a rotating nozzle through the guide pipe. This utility model, a rapid water sampling and automatic cleaning device, uses a water storage tank on the top of the functional cover. When the water pump is turned on, the cleaning liquid in the water storage tank is sprayed into the inside of the barrel body through the guide pipe and the rotating nozzle to clean it. By setting up an electric hydraulic rod and cleaning blocks, dirt on the inner walls of both sides of the barrel body can be effectively scraped off. The combination of the two can make the inside of the sampler more thoroughly cleaned, and the operation is convenient and quick.

[0004] In their daily work, the inventors discovered that during the sampling process using the water sampler body, there was a problem: because the existing sampler body did not have an anti-clogging self-cleaning device installed inside, a lot of impurities would enter the sampler body during the water sampling process, interfering with the detection and affecting the representativeness of the sample.

[0005] Therefore, it is necessary to provide a new anti-clogging self-cleaning device for water quality samplers to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where the sampler body lacks an anti-clogging self-cleaning device, resulting in numerous impurities entering the sampler body during water sampling, interfering with detection and affecting the representativeness of the sample. Therefore, this invention proposes an anti-clogging self-cleaning device for water quality samplers.

[0007] To solve the above-mentioned technical problems, this utility model provides an anti-clogging self-cleaning device for a water quality sampler, comprising: a pull rope, a pull ring fixedly connected inside the pull rope, a connecting post rotatably connected to the arc surface of the pull ring, an auxiliary structure on the lower surface of the connecting post, the auxiliary structure including a sampler body, the sampler body rotatably connected to the connecting post, a guide tube fixedly and throughly connected inside the sampler body, a counterweight ring and a fixing plate fixedly connected to the arc surface of the sampler body, a limit groove formed on the inner wall of the fixing plate, a moving block slidably connected to the inner wall of the limit groove, and a connecting rod fixedly connected to the side of the moving block away from the sampler body. The sampler body has a sliding plate connected to its inner wall. Two floats and a fixed block are fixedly connected to the side of the sliding plate away from the connecting column. A connecting plate is fixedly connected to the side of the fixed block away from the sliding plate. The connecting plate is fixedly connected to the connecting plate. A positioning plate is fixedly connected to the side of the sampler body away from the connecting column. A fixed disk is fixedly connected to the inner wall of the sampler body. Several filter holes are opened on the inner wall of the fixed disk. A rotating column is rotatably connected to the side of the fixed disk away from the connecting column. Several turbine blades and two mounting plates are fixedly connected to the arc surface of the rotating column. A cleaning brush is fixedly connected to the side of the mounting plate near the fixed disk.

[0008] The aforementioned components achieve the following effect: when personnel need to sample the water source, the water entering the sampler body can be filtered through the filter holes inside the water collection cylinder, and impurities attached to the fixed plate can be cleaned by the cleaning brush. This prevents excessive impurities from entering the sampler body and interfering with the detection and affecting the representativeness of the sampling.

[0009] Preferably, a limiting rod is fixedly connected to the inner wall of the limiting groove, and the limiting rod is slidably connected to the moving block.

[0010] The effect achieved by the above components is that the limiting rod can limit the movement of the moving block and prevent the moving block from becoming misaligned during the sliding process on the inner wall of the limiting groove.

[0011] Preferably, a sealing gasket is fixedly connected to the side of the movable plate near the positioning plate, and the sealing gasket is slidably connected to the sampler body.

[0012] The effect achieved by the above components is that the sealing gasket can increase the sealing between the moving plate and the positioning plate, and can prevent water from flowing out between the moving plate and the positioning plate.

[0013] Preferably, a protective pad is fixedly connected to the side of the connecting plate near the sampler body, and the protective pad has a rectangular cross-section.

[0014] The effect achieved by the above components is that the protective pad can protect the connecting plate and the sampler body, and can prevent the connecting plate from directly contacting the sampler body.

[0015] Preferably, a handle is fixedly connected to the arc surface of the sampler body, and the handle is U-shaped.

[0016] The effect achieved by the above components is that the handle makes it easy for personnel to move the sampler body, which can improve the ease of operation for personnel.

[0017] Preferably, the movable plate is an ABS plastic plate.

[0018] The effect achieved by the above components is that the ABS plastic sheet is lightweight, high-strength, and corrosion-resistant, which can prevent the moving sheet from deforming during short-term use.

[0019] Compared with related technologies, the anti-clogging self-cleaning device for water quality samplers provided by this utility model has the following beneficial effects:

[0020] By setting up an auxiliary structure, when personnel need to use the sampler body to sample the water source, the auxiliary structure can assist personnel in sampling the water source. This can prevent excessive impurities from entering the sampler body and interfering with detection and affecting the representativeness of the sampling, thereby improving the accuracy of sampling and increasing the sampling efficiency of personnel.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figure 1 The present invention provides a self-cleaning anti-clogging device for a water sampler, comprising: a pull rope 1, a pull ring 2 fixedly connected inside the pull rope 1, a connecting post 4 rotatably connected to the arc surface of the pull ring 2, and an auxiliary structure 3 provided on the lower surface of the connecting post 4.

[0031] In the embodiments of this utility model, please refer to Figures 2 to 6The auxiliary structure 3 includes a sampler body 301, which is rotatably connected to a connecting column 4. A guide tube 302 is fixedly and continuously connected inside the sampler body 301. A counterweight ring 305 and a fixing plate 306 are fixedly connected to the arc surface of the sampler body 301. A limit groove 307 is formed on the inner wall of the fixing plate 306. A moving block 309 is slidably connected to the inner wall of the limit groove 307. A connecting plate 310 is fixedly connected to the side of the moving block 309 away from the sampler body 301. A moving plate 314 is slidably connected to the inner wall of the sampler body 301. Two floats 315 and a fixing plate 315 are fixedly connected to the side of the moving plate 314 away from the connecting column 4. Block 313, a connecting plate 311 is fixedly connected to the side of the fixed block 313 away from the moving plate 314, the connecting plate 311 is fixedly connected to the connecting plate 310, a positioning plate 317 is fixedly connected to the side of the sampler body 301 away from the connecting column 4, a fixed plate 318 is fixedly connected to the inner wall of the sampler body 301, a number of filter holes 303 are opened on the inner wall of the fixed plate 318, a rotating column 319 is rotatably connected to the side of the fixed plate 318 away from the connecting column 4, a number of water turbine blades 320 and two mounting plates 321 are fixedly connected to the arc surface of the rotating column 319, and a cleaning brush 322 is fixedly connected to the side of the mounting plate 321 near the fixed plate 318. When personnel need to sample the water source, the water entering the sampler body 301 can be filtered through the filter holes 303 inside the water collection cylinder. Then, the cleaning brush 322 cleans impurities adhering to the fixed plate 318, preventing excessive impurities from entering the sampler body 301 and interfering with detection or affecting the representativeness of the sampling. A limiting rod 308 is fixedly connected to the inner wall of the limiting groove 307, and the limiting rod 308 is slidably connected to the moving block 309. The limiting rod 308 can limit the moving block 309, preventing misalignment during sliding within the limiting groove 307. A sealing gasket 316 is fixedly connected to the side of the moving plate 314 near the positioning plate 317, and the sealing gasket 316 is slidably connected to the sampler body 301. The sealing gasket 316 increases the seal between the moving plate 314 and the positioning plate 317, preventing water from flowing out between them. A protective gasket 312 is fixedly connected to the side of the connecting plate 311 closest to the sampler body 301. The protective gasket 312 has a rectangular cross-section. The protective gasket 312 protects the connecting plate 311 and the sampler body 301, preventing direct contact. A handle 304 is fixedly connected to the arc surface of the sampler body 301. The handle 304 is U-shaped. The handle 304 facilitates movement of the sampler body 301, improving ease of operation. The moving plate 314 is made of ABS plastic. ABS plastic is lightweight, high-strength, and corrosion-resistant, preventing deformation of the moving plate 314 during short-term use.

[0032] The working principle of the anti-clogging self-cleaning device for a water sampler provided by this utility model is as follows: When a person needs to use the sampler body 301 to sample a water source, the person can hold the pull rope 1 with one hand and then put the sampler body 301 into the water. The counterweight ring 305 will drive the sampler body 301 to move vertically downward until the sampler body 301 is completely submerged in the water. After the sampler body 301 is completely submerged in the water, the two floats 315 will generate buoyancy. At this time, the two floats 315 will drive the moving plate 314 to move upward. The moving plate 314 will drive the sealing gasket 316 and the handle 304 to move upward. The fixing block 313 will drive the connecting plate 311 to move upward. The connecting plate 311 will drive the protective gasket 312 and the connecting plate to move upward. 310 moves upward, and the connecting plate 310 drives the moving block 309 to move upward. The moving block 309 slides on the arc surface of the limiting rod 308. The limiting rod 308 can limit the moving block 309 and prevent it from being misaligned during sliding on the inner wall of the limiting groove 307 until the protective pad 312 abuts against the sampler body 301. The protective pad 312 can protect the connecting plate 311 and the sampler body 301 and prevent the connecting plate 311 from directly contacting the sampler body 301. At this time, water will pass between the positioning plate 317 and the moving plate 314. During the process of the water source entering the sampler body 301, the water source will drive several water turbine blades 320 to rotate. The blade 320 drives the rotating column 319 to rotate, which in turn drives the two mounting plates 321 to rotate. The mounting plates 321 then drive the cleaning brush 322 to rotate. The cleaning brush 322 rotates on the lower surface of the fixed plate 318. Water then enters the sampler body 301 through the filter hole 303. When the sampler body 301 is full of water, the operator pulls the rope 1. The rope 1 moves the pull ring 2 upward, which in turn moves the connecting column 4 upward. The connecting column 4 then moves the sampler body 301 upward. During this upward movement, the water inside the sampler body 301 generates a counterforce, which in turn moves the moving plate 314 downward. The sampler is made of ABS plastic, which is lightweight, high-strength, and corrosion-resistant. This prevents deformation of the moving plate 314 during short-term use until the sealing gasket 316 abuts against the positioning plate 317. The sealing gasket 316 increases the seal between the moving plate 314 and the positioning plate 317, preventing water leakage. When personnel need to divert water from inside the sampler body 301 to the sampling bottle, they can rotate the sampler body 301 using the handle 304, causing the pull ring 2 to point downwards. The guide tube 302 can then be inserted into the sampling bottle for collection. The handle 304 facilitates movement of the sampler body 301.This can improve the ease of operation for users.
