Abstract
Description
Technical Field
[0001] This utility model relates to the field of water resource sampling technology, and in particular to a hydrological water resource sampling device. Background Technology
[0002] The importance of hydrological and water resource sampling devices is self-evident in water resource research, environmental protection, and numerous water-related industries. Whether tracing the sources of pollution in rivers and lakes to provide a basis for ecological restoration, or ensuring the safety and reliability of urban water supply to meet residents' daily water needs, all rely on the accurate collection of water samples. From vast, open water bodies to harsh industrial environments, sampling devices need to cope with a variety of complex environments and ensure that water samples are not contaminated or leaked during transportation and operation. This guarantees the smooth progress of subsequent complex water quality analysis processes and provides solid data support for water resource-related decision-making.
[0003] Take the hose connection as an example. Generally, one end of a regular rubber or plastic hose is simply slipped onto the interface of the peristaltic pump, and the other end is inserted into the water source. There is no sturdy design for the hose. When the peristaltic pump starts, the hose is prone to shaking due to the vibration generated by the pump and the impact of the water flow. Over time, the connection between the hose and the interface gradually loosens, which not only affects the efficiency of water sampling but also makes the water sampling process unpredictable. As for the placement of the sample bottle, it is usually placed on a simple tray or shelf, relying on the weight of the bottle itself to maintain balance. Once there is a slight external vibration, such as the bumps of the vehicle during transportation or accidental collisions by the operator, the sample bottle will shake. This not only causes water sample to splash out and result in sample loss, but also causes uneven mixing of the water sample inside the bottle due to shaking, changing the original state of the water sample and affecting the accuracy of subsequent water quality analysis results.
[0004] When using a peristaltic pump to extract water samples, the water flow is not constant. Impurities in the water and sudden changes in flow velocity can cause a sharp rise in pressure inside the pipe. Under high pressure, the hose can easily break free from the interface. Once it breaks free, not only will a large amount of the valuable water sample being collected be lost, polluting the surrounding environment, but the entire sampling work will also be forced to stop. The equipment will need to be repaired, cleaned, and prepared again before sampling can resume. This affects the continuity of water sampling work and consumes a lot of manpower, material resources, and time. Therefore, a hydrological and water resource sampling device is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figure 1 - Figure 3This utility model provides an embodiment of a hydrological and water resource sampling device, comprising a body 1, which is integrally injection molded from engineering plastic material, ensuring both the stability of the overall structure and good corrosion resistance, adapting to different water quality environments. A caster wheel 2 is fixedly connected to the bottom of the body 1. The caster wheel 2 is made of high-quality rubber material wrapped around a metal hub, reducing the impact of vibration on the internal components of the device during transportation. A hinge 8 is fixedly connected to the side wall of the body 1. The hinge 8 undergoes special rust-proof treatment to ensure that it will not rust or jam even after long-term use in a humid water environment, thus ensuring... The cover plate 3 opens and closes smoothly. The hinge 8 is fixedly connected to the side wall of the cover plate 3. The main body of the cover plate 3 is also made of engineering plastic material matching the body 1. A connecting platform 5 is fixedly connected to the top of the cover plate 3. The connecting platform 5 is made of aluminum alloy with an oxidized surface, providing a certain degree of anti-slip performance and facilitating the connection of other auxiliary equipment. A peristaltic pump 6 is fixedly connected to one side of the connecting platform 5. The pump body shell of the peristaltic pump 6 is made of wear-resistant and corrosion-resistant polycarbonate material. A flexible tube 11 is installed inside the peristaltic pump 6. The flexible tube 11 is made of medical-grade silicone, possessing flexibility, corrosion resistance, and biological properties. The system is designed to ensure compatibility, guaranteeing that the water sample remains uncontaminated during transport and withstands the prolonged pressure of the peristaltic pump 6 without easily breaking. An operation panel 7 is fixedly connected to the side wall of the connecting platform 5. The operation panel 7 features a high-resolution, waterproof and dustproof LCD screen and a row of touch-sensitive, backlit silicone buttons. Operators can set sampling parameters such as sampling time, sampling volume, and sampling frequency via the operation panel 7. A water inlet 9, made of stainless steel with internal threads, is also fixedly connected to the side wall of the connecting platform 5 for easy connection to external water pipes of different specifications. The machine body 1 has a sliding connection to the side wall of the pull rod 10, which is made of lightweight aluminum alloy tubing with a frosted surface. It is comfortable to hold and not easy to slip. When long-distance movement of the device is required, the pull rod 10 can be pulled out and used with the casters 2 to achieve quick and convenient handling. The side wall of the connecting platform 5 is equipped with a stabilizing component to deal with the situation of the tubing 11 falling off during the sampling process and to ensure the stability of the sampling. The machine body 1 is equipped with a limit component to effectively fix and limit the sample bottle 26, preventing the parts from shifting or colliding during transportation or operation, and further improving the reliability of the device.
[0035] The stabilizing component includes a slide rail 12, made of high-strength aluminum alloy through extrusion and anodized. This provides wear resistance, allowing it to withstand prolonged and frequent sliding friction, and also excellent corrosion resistance, ensuring structural stability even in harsh environments involving moisture and various water samples. The bottom of the slide rail 12 is fixedly connected to the side wall of the connecting platform 5. The side wall of the connecting platform 5 has two support plates 13, injection-molded from engineering plastic with internally distributed reinforcing ribs to further enhance rigidity and withstand pressure and impact. The side wall of the support plates 13 is slidably connected to the top of the slide rail 12. A fixing block 29 is fixedly connected to the side wall of the connecting platform 5. The fixing block 29 is made of stainless steel and is rust-resistant. A rotating block 17 is rotatably connected to the side wall of the fixing block 29. The two are flexibly connected via a pin. The pin surface is hardened to enhance hardness and wear resistance, ensuring the rotating block 17 can rotate around the pin. The side wall of the rotating block 17 is fixedly connected to... The support plate 13 is equipped with a handle 16, which is covered with a soft and non-slip rubber material. This not only provides a comfortable feel and makes it easy for operators to grip and apply force, but also effectively prevents hand slippage in wet environments, ensuring the accuracy and safety of operation. A fixing post 15 is fixedly connected to one side of the support plate 13. The fixing post 15 is also made of stainless steel and has a hollow design to house the spring 14. The spring 14 is made of alloy spring steel and has undergone heat treatment to have an elastic coefficient. It can store sufficient elastic potential energy when compressed and quickly return to its original shape after the pressure is released. Both ends of the spring 14 are fixedly connected to the side walls of the two fixing posts 15. A clamp 18 is fixedly connected to the other side of the support plate 13. The clamping part of the clamp 18 is made of silicone material with a non-slip texture. This design can not only hold the target object to prevent it from loosening or falling off, but also avoid damage to the clamped object, ensuring that the stabilizing component can function in various complex working conditions.
[0036] Specifically, when starting the water intake operation, the first task is to select the placement point of the hydrological and water resources sampling device based on the surrounding environment of the water source, such as a flat open space by the river or a stable embankment by the lake, and ensure that it is in a horizontal and stable state to minimize external vibration interference. Then, the operator inserts one end of the hose 11 into the water inlet 9 and the other end of the hose 11 into the water resource to be sampled, ensuring that the depth is appropriate to obtain a representative water sample. Subsequently, the peristaltic pump 6 is started to drive the hose 11 to operate. As the pump operates, the water flows steadily along the hose 11 and finally flows into the sample bottle 26 on the placement plate for storage. However, during the continuous operation of the peristaltic pump 6, due to fluctuations in water pressure, the hose 11 often shows signs of loosening due to the pressure generated during operation. At this time, the operator needs to turn the handle 16. Since the fixed blocks 29 are fixed on both sides of the support plate 13, they drive the rotating block 17 to rotate, which in turn drives the support plate 13 to move above the slide rail 12. At the same time, the spring 14 inside the fixed column 15 is compressed, pushing the clamps 18 on both sides to clamp in the middle, thus fixing the hose 11. When the sampling task is successfully completed and the sampling device is no longer used, the handle 16 is turned again to drive the rotating block 17 to rotate. The reverse operation causes the support plate 13 to move above the slide rail 12, and the spring 14 retracts, releasing the fixation of the hose 11. This effectively avoids the situation where the hose 11 falls off due to a sudden increase in pressure, avoids water splashing and environmental pollution, and avoids the risk of equipment damage due to accidental component detachment, ensuring the efficiency and safety of each sampling operation.
[0037] Reference Figure 1 , Figure 3 and Figure 5A handle 4 is fixedly connected to one side of the machine body 1. Its main frame is made of extruded aluminum alloy, which is not only lightweight and easy for operators to grip and lift, reducing fatigue during long-term handling, but also ensures the safety and convenience of moving the device. The machine body 1 contains a sample retention bottle 26, which is made of borosilicate glass. This type of glass has a low coefficient of thermal expansion and can withstand rapid temperature changes. It is not easy to break, whether for high-temperature sterilization or storing water samples in cold outdoor environments. The limiting component includes clamp 2 19, which is made of engineering plastic injection molding and has an appropriate amount of glass fiber added inside to enhance its rigidity and wear resistance. The second clamp 19 has its outer wall set inside the machine body 1. A movable clamping plate 21 is fixedly connected to the bottom of the second clamp 19. A limiting groove 28 is fixedly connected inside the machine body 1. The limiting groove 28 is made of stainless steel plate bent and welded, with a smooth and flat surface. The outer wall of the second clamp 19 is slidably connected to it via a low-friction slider, ensuring that the second clamp 19 can slide left and right within the limiting groove 28 to adjust the clamping position. A sliding column 25 is set inside the machine body 1. The sliding column 25 is made of stainless steel and manufactured using high-precision machining technology, with a smooth, mirror-like cylindrical surface. The outer wall of the sliding column 25 is slidably connected inside the movable clamping plate 21, which is also made of engineering plastic. To reduce weight and enhance structural strength, a honeycomb-shaped reinforcing rib structure is designed internally. A limiting block 27, a circular stainless steel sheet, is fixedly connected to one end of the sliding column 25, effectively preventing the sliding column 25 from detaching from the moving clamp 21 during movement. The bottom of the limiting block 27 is fixedly connected to the top of another moving clamp 21. A second spring 23 is fitted onto the outer wall of the sliding column 25. The second spring 23 is made of alloy spring steel and has an elastic coefficient, providing appropriate elastic force according to different stress conditions. One end of the second spring 23 is fixedly connected to the side wall of the moving clamp 21, and the other end is fixedly connected to the side wall of another moving clamp 21. The machine body 1 is internally equipped with… The guide rail 20 is made of high-strength aluminum alloy. After anodizing, it not only has wear resistance but also good guiding properties. The bottom of the movable clamping plate 21 is slidably connected to the top of the guide rail 20. The machine body 1 is rotatably connected to the locking post 22, which is made of stainless steel. The top of the locking post 22 is fixedly connected to the fixing plate 24. Both sides of the fixing plate 24 are flexibly rotatably connected to the bottom of the movable clamping plate 21 through pins. This ingenious connection method enables the components to work together. When the equipment is subjected to external forces such as shaking, it responds quickly and allows the clamp 2 19 to clamp the sample bottle 26, ensuring the safety of the water sample and the accuracy of the test.
[0038] Specifically, if the machine body 1 is moved due to actual operational needs, such as transporting the sampling device to a transport vehicle or moving its position in a confined space, the machine body 1 will shake. This shaking will cause the sample bottle 26 placed inside the machine body 1 to shake violently. To mitigate this hazard, the operator needs to press the sample bottle 26. At this moment, the second spring 23 retracts. As the second spring 23 retracts, it moves along the outer wall of the sliding column 25. The sliding column 25 engages with the inside of the moving clamp 21, thereby causing the sliding column 25 to move within the moving clamp 21. Simultaneously, the moving clamp 21 begins to slide above the guide rail 20. During the sliding of the moving clamp 21, the connected locking pin 22 also rotates around its axis inside the machine body 1. The rotation causes the fixed plate 24 and the movable clamping plate 21 above it to rotate, which in turn causes the clamping fixture 19 above the movable clamping plate 21 to move. The clamping fixture 19 slides inside the limiting groove 28. Since the contact surface between the clamping fixture 19 and the sample bottle 26 is inclined, the clamping fixtures 19 on both sides will push towards the middle, thus clamping the sample bottle 26. The water sample in the sample bottle 26 can be preserved in a relatively stable environment, effectively isolating external shaking, collision and other interference factors. Until the water sample is sent to a professional laboratory for testing, it can maintain its original state to the greatest extent, laying a solid foundation for a series of complex and precise testing processes. This effectively ensures the accuracy and reliability of the water sample test data and provides solid data support for water resource research, environmental monitoring and other work.
[0039] Working principle: When water sampling is required, first place the hydrological water resource sampling device in a suitable position, then insert one end of the hose 11 into the water inlet 9 and the other end into the water resource. Start the peristaltic pump 6, which drives the hose 11 to operate, and the water flows into the sample bottle 26 on the placement plate for storage. When the hose 11 becomes loose due to the pressure generated by the operation of the peristaltic pump 6, the handle 16 needs to be turned. Since the fixing blocks 29 are fixed on both sides of the support plate 13, the rotating block 17 is then rotated, which in turn drives the support plate 13. The device moves above the slide rail 12, simultaneously compressing the spring 14 inside the fixing column 15. This causes the clamps 18 on both sides to clamp towards the center, thus securing the hose 11. When the sampling device is no longer in use, the handle 16 is turned to rotate the rotating block 17, which then moves the support plate 13 above the slide rail 12. Simultaneously, the spring 14 inside the fixing column 15 retracts, releasing the hose 11 from its fixation. This prevents the hose 11 from detaching due to a sudden increase in pressure, thereby reducing the risk of water splashing and equipment damage.
[0040] After sampling is completed, the pushing body 1 will shake, causing the sample bottle 26 to shake. At this time, by placing the sample bottle 26, the spring 23 will be stretched due to the pressure applied to the sample bottle 26, thus moving the spring 23 against the outer wall of the sliding column 25. This then moves the sliding column 25 inside the moving clamp 21. The limiting block 27 limits the sliding column 25 and fixes it to the top of the moving clamp 21 to prevent displacement. The moving clamp 21 then slides above the guide rail 20, simultaneously moving the clamp... The column 22 rotates inside the body 1, which in turn drives the fixed plate 24 and the movable clamping plate 21 above the column 22 to rotate. This allows the clamp 29 above the movable clamping plate 21 to slide inside the limiting groove 28. Since the contact surface between the clamp 29 and the sample bottle 26 is inclined, the clamps 29 on both sides move towards the middle, thus clamping the sample bottle 26. By clamping the sample bottle 26, the water sample can be preserved in a relatively stable environment until testing, ensuring the accuracy and reliability of the water sample test data.
