Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water quality monitoring technology, and specifically relates to a water sample collection device for water quality monitoring. Background Technology
[0002] Water quality testing is the process of measuring and analyzing various physical, chemical, and biological properties of water bodies. Its purpose is to ensure that water sources meet safety standards and are suitable for drinking, industrial, agricultural, or ecological use. During water quality monitoring, appropriate sample collection devices are used to collect water samples from the monitored water body. The collected water samples can be qualitatively and quantitatively analyzed for pollutants in the water under laboratory conditions, thereby reflecting the stage-by-stage changes and evolution trends of water quality and providing a strong basis for water quality monitoring work.
[0003] A prior art patent, CN218444640U, discloses a water quality monitoring water sample collection device. This patent includes a base plate, a placement box, a moving assembly, a support assembly, a placement plate, and a telescopic rod. The placement box is located on the base plate, the moving assembly is located on the top of the placement box, the support assembly is symmetrically arranged on the base plate, the placement plate is located on the top of the placement box, and the telescopic rod is located on the placement plate. The moving assembly includes a moving motor, a moving plate, a moving helical rack, a moving support plate, a moving worm gear, a moving worm wheel, a drive plate, and a spray nozzle. The device uses a telescopic rod to move a water pump, changing the pumping depth. A moving component moves the nozzle, spraying water samples from different depths into the sample storage cup, achieving sampling at different depths with a single application. However, in practical use, the following shortcomings exist: Firstly, the device lacks a filtration mechanism during water sample extraction, allowing sand and other foreign matter to easily mix into the sample. Solid particles in the water can cause equipment blockage or damage during testing, increasing maintenance costs and affecting the accuracy of the tests.
[0004] Therefore, a water quality monitoring water sample collection device is needed to solve the problem of the lack of filtration mechanism in the sampling devices of the existing technology. Utility Model Content

[0020] The present invention will be further described below with reference to the embodiments.
[0021] Please see Figure 1-4 This utility model provides a water quality monitoring water sample collection device, including a base plate 1, a plurality of support columns 2 fixedly connected to the bottom of the base plate 1, and universal self-locking wheels 3 fixedly connected to the bottom of each of the support columns 2. A convex frame 4 is fixedly connected to the top of the base plate 1, a water pump 5 is fixedly connected to the top of the convex frame 4, a water pump 6 is fixedly connected to one side of the water pump 5, a telescopic hose 7 is fixedly connected to the bottom of the water pump 6, a sampling head 8 is fixedly connected to the bottom of the telescopic hose 7, two brackets 9 are fixedly connected to the top of the base plate 1, a take-up and release roller 10 is rotatably connected between the two brackets 9, a servo motor 11 is fixedly connected to the rear end of the take-up and release roller 10, two pull cables 12 are fixedly connected to the outer wall of the take-up and release roller 10, and a counterweight ring 13 corresponding to the telescopic hose 7 is fixedly connected to the bottom of the two pull cables 12. A filter mechanism 14 is provided inside the water pump 6, a water outlet pipe 15 is fixedly connected to the top of the water pump 5, a rotating shaft 16 is rotatably connected to the top of the base plate 1, a turntable 17 is fixedly connected to the top of the rotating shaft 16, and a plurality of water storage cylinders 18 are fixedly connected to the top of the turntable 17.
[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the output end of the servo motor 11 passes through one of the brackets 9 and is fixedly connected to the take-up and release roller 10. The servo motor 11 can precisely adjust the rotation angle and speed of the output shaft according to the control signal. By fixing the output end of the servo motor 11 to the take-up and release roller 10, precise control of the take-up and release roller 10 can be achieved, making the take-up and release of the telescopic hose 7 more stable and controllable. At the same time, the output end of the servo motor 11 is directly connected to the take-up and release roller 10 through the bracket 9, avoiding the use of complex transmission devices and simplifying the mechanical structure. This can reduce the wear, failure and maintenance needs of the transmission system.
[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the inner wall of the counterweight ring 13 is fixedly connected to the outer wall at the bottom of the telescopic hose 7. The counterweight ring 13 is fixed to the outer wall at the bottom of the telescopic hose 7, which helps to increase the stability of the telescopic hose 7 and prevents the hose from swinging unnecessarily or moving out of the predetermined position due to factors such as water flow, wind force or equipment vibration during use. This ensures the stability of the water sampling device in different working environments and avoids the telescopic hose 7 swinging, which affects the sampling accuracy. The counterweight ring 13 helps to keep the hose vertical by increasing the weight at the bottom of the hose and prevents the hose from rising or shifting to the side. Especially when sampling in deep water areas, it ensures that the sampling head 8 is always at the predetermined depth and position.
[0024] Further as Figure 1 and Figure 2 As shown, it is worth noting that the inner walls of multiple water storage cylinders 18 are slidably connected to inner water storage tanks. These inner tanks can be removed individually for easy cleaning and replacement. Users do not need to clean the entire water storage cylinder 18; only the inner tank needs to be cleaned or replaced. This greatly improves equipment maintenance efficiency, especially after long-term use, when contaminants or deposits may accumulate in the inner tanks of the water storage cylinders 18. This allows for convenient cleaning, ensuring the equipment maintains good working condition over the long term. Using sliding inner tanks avoids cross-contamination between different batches of water samples. Each time a sample is used, only the inner tank needs to be replaced, preventing the influence of previous water samples remaining on the inner walls of the water storage cylinders 18, thus improving sampling accuracy and reliability. Furthermore, different water samples can be placed in different inner tanks for batch management. Each inner tank can be independently numbered, labeled, and stored, facilitating tracking and recording of different water samples by management personnel. This not only improves sample management efficiency but also effectively avoids confusion and errors.
[0025] As can be seen from the above working process: by setting up the telescopic hose 7 in conjunction with the counterweight ring 13, the servo motor 11 is turned on to drive the take-up and release roller 10 to take up and release, thereby driving the counterweight ring 13 to rise and fall through the pull cable 12, so that the position of the sampling head 8 can be raised and lowered, thus enabling water samples to be collected at different depths, making the sampling more thorough and facilitating subsequent testing.
[0026] Further as Figure 4 As shown, it is worth noting that the filtration mechanism 14 includes a filter port 1401 fixedly connected to the bottom of the pumping pipe 6. A filter cylinder 1402 is slidably connected to the inner wall of the filter port 1401. An installation plate 1403 is fixedly connected to the bottom of the filter cylinder 1402. Multiple fixing bolts 1404 are rotatably connected to the bottom of the installation plate 1403. By setting up the filtration mechanism 14, before the sampling water source enters the water pump 5 from the pumping pipe 6, the filter cylinder 1402 can filter out foreign objects such as sand and gravel in the water, preventing large particles in the water from entering the water pump 5, avoiding wear or blockage of the water pump 5, and extending the service life of the equipment. At the same time, after removing solid matter, the concentration of dissolved pollutants in the water sample can be measured more accurately, avoiding the influence of the presence of solid matter on the test results.
[0027] Further as Figure 4 As shown, it is worth noting that the inner surface of the top of the water pumping pipe 6 is provided with a baffle corresponding to the filter cylinder 1402. The baffle cooperates with the filter cylinder 1402 to separate the inner wall of the water pumping pipe 6, ensuring that solid particles in the water sample are blocked and filtered when they enter the inner wall of the filter cylinder 1402, while the remaining water sample flows out through the through holes on the surface of the filter cylinder 1402 and continues to move forward.
[0028] The solution has the following working process: In actual use, the pusher moves to the designated position and locks the multiple universal self-locking wheels 3 in place. The servo motor 11 is turned on to drive the take-up and release rollers 10 to take up and release, thereby driving the counterweight ring 13 to descend through the pull cable 12, so that the sampling head 8 is lowered. After descending to the designated depth, the water pump 5 is turned on to drive the sampling head 8 to extract water. The filter cylinder 1402 filters out foreign objects such as sand and gravel in the water. The filtered water sample is discharged from the outlet pipe 15 and collected in the water storage cylinder 18.
[0029] In summary: By setting up a telescopic hose 7 in conjunction with a counterweight ring 13, and activating the servo motor 11 to drive the take-up and release roller 10, the counterweight ring 13 is raised and lowered via the pull cable 12, thereby raising and lowering the sampling head 8. This allows for the collection and sampling of water at different depths, resulting in more thorough sampling and facilitating subsequent testing. By setting up a filtration mechanism 14, the filter cartridge 1402 can filter out sand and other foreign objects in the water before the sampling water source enters the water pump 5 from the pump pipe 6, preventing large particles from entering the water pump 5, avoiding wear or blockage of the equipment, extending the service life of the equipment. At the same time, after removing solid matter, the concentration of dissolved pollutants in the water sample can be measured more accurately, avoiding the influence of the presence of solid matter on the test results.
