Description

Technical Field

[0001] This utility model relates to the field of water sample sampling technology for total phosphorus detection, and in particular to a quantitative aspirator for total phosphorus detection water samples. Background Technology

[0002] The total phosphorus water sampling device is a key piece of equipment in environmental monitoring and water quality analysis. It is primarily used to collect total phosphorus content data from water bodies. Through precise mechanical design and chemical analysis principles, it ensures a contamination-free and representative sampling process. This device achieves efficient and accurate sample collection through automated or semi-automated operation and is widely used in wastewater treatment, river and lake monitoring, and industrial wastewater testing. Its core functions include sample positioning, quantitative collection, and sealed preservation, ensuring the accuracy and reliability of subsequent laboratory analysis.

[0003] In current water sample testing technologies, the quantitative sampling process for detecting total phosphorus is quite challenging, leading to problems such as low sample collection efficiency, increased containment difficulty, and a heavier testing burden. Because traditional sampling methods cannot achieve accurate quantification, some samples cannot be effectively transferred to subsequent testing equipment due to excessive quantity, resulting in resource waste and reduced testing efficiency. At the same time, excessive sample accumulation may lead to insufficient containment space or increased safety risks. These problems not only affect the convenience of testing operations but also increase laboratory operating costs and staff workload.

[0004] In response to this technical problem, this application proposes a quantitative sampling device for total phosphorus detection in water samples. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quantitative water sample extractor for total phosphorus detection. Water enters the water sampler body through the inlet ring, and after the sealing plate is reset, the water sample flows into the collection bottle, achieving quantitative sampling and improving convenience and accuracy.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] Furthermore, the adjustment assembly includes a screw fixedly connected to the left end of the adjustment column, the inner wall of the right end of the moving rod is threaded to the outer wall of the left end of the screw, a water inlet ring is fixedly connected to the left end of the outer wall of the water dispenser body, and a plurality of springs are fixedly connected to the inner wall of the water inlet ring. Each spring has a blocking ball installed at one end opposite to the other, and the outer wall of the blocking ball is in close contact with the outer wall of the water dispenser body.

[0009] Furthermore, a sleeve is fixedly connected to the left end of the pull rod, the outer wall of the moving rod is slidably connected to the inner wall of the sleeve, and a scale block is fixedly connected to the right end of the adjusting column, with a scale groove formed on the outer wall of the scale block.

[0010] Furthermore, a second sealing plate is fixedly connected to the outer wall of the left end of the movable rod, and a first sealing plate is fixedly connected to the outer wall of the sleeve.

Detailed Implementation

[0024] 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.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a total phosphorus water sample quantitative aspirator, comprising a water sampler body 1, a counterweight 3 fixedly connected to the outer wall of the left end of the water sampler body 1, a connecting ring 4 fixedly connected to the bottom end of the rod of the water sampler body 1, a threaded groove provided on the inner wall of the connecting ring 4, and a collection bottle 5 detachably connected to the connecting ring 4 through the threaded groove, a transition ring 9 rotatably connected to the right end of the water sampler body 1, an adjusting column 10 slidably connected to the inner wall of the transition ring 9, a moving rod 18 connected to the left end of the adjusting column 10 through an adjusting assembly, the adjusting assembly including a screw 13 fixedly connected to the left end of the adjusting column 10, and the inner wall of the right end of the moving rod 18 threadedly connected to the outer wall of the left end of the screw 13. (Refer to...) Figure 4A water inlet ring 2 is fixedly connected to the left end of the outer wall of the water dispenser body 1. Several springs 7 are fixedly connected to the inner wall of the water inlet ring 2. A blocking ball 8 is installed on the opposite end of each spring 7. The outer wall of the blocking ball 8 is in close contact with the outer wall of the water dispenser body 1. A sleeve 12 is fixedly connected to the left end of the opposite end of the pull rod 6. The outer wall of the moving rod 18 is slidably connected to the inner wall of the sleeve 12. A scale block 11 is fixedly connected to the right end of the adjusting column 10. A scale groove is opened on the outer wall of the scale block 11. A sealing plate 2 19 is fixedly connected to the outer wall of the left end of the moving rod 18. A sealing plate 14 is fixedly connected to the outer wall of the sleeve 12. The outer walls of the sealing plate 2 19 and the sealing plate 14 are in close contact with the inner wall of the water dispenser body 1. A spring 3 21 is installed on the outer wall of the sleeve 12. The left end of the spring 3 21 is fixedly connected to the inner wall of the right end of the water dispenser body 1. The right end of the spring 3 21 is fixedly connected to the left end of the pull rod 6.

[0026] Reference Figure 5 Pull rods 6 are slidably connected to the outer walls of both the front and rear ends of the water dispenser body 1. A float ball 17 is connected to the right side of the opposite end of the pull rod 6 via a float assembly. The float assembly includes connecting blocks 22 that are fixedly connected to both the front and rear sides of the right end of the water dispenser body 1. Claws 15 are slidably connected to the inner walls of the connecting blocks 22. The opposite ends of the claws 15 are detachably connected to the opposite end of the pull rod 6. Springs 20 are fixedly connected to the opposite ends of the inner walls of the claws 15. The opposite ends of the springs 20 are fixedly connected to the inner walls of the opposite ends of the connecting blocks 22. A traction rope 16 is installed on the outer walls of the opposite ends of the claws 15. The right end of the traction rope 16 is fixedly connected to the outer wall of the left end of the float ball 17.

[0027] Specifically: First, the collection bottle 5 is installed at the connecting ring 4 through the threaded groove structure to ensure a stable connection. Then, the pull rod 6 is compressed so that it engages with the claw 15 at the connecting block 22. Through the action of the second spring 20, the claw 15 can be firmly embedded inside the pull rod 6, thereby fixing it. Subsequently, according to the scale groove on the scale block 11, the adjusting column 10 is rotated so that the screw 13 drives the moving rod 18 to move inside the sleeve 12. This operation will shorten the distance between the second sealing plate 19 and the first sealing plate 14, thereby reducing the volume cavity they form in the water collector body 1, preparing for subsequent quantitative sampling.

[0028] When the device is thrown into the water, the weight of the counterweight 3 will cause the water dispenser body 1 to sink into the water. At the same time, the length of the traction rope 16 and the floating effect of the floating ball 17 will work together to cause the buoyancy generated by the floating ball 17 to drive the claw 15 to retract relatively through the traction rope 16. This retraction action causes the pull rod 6 to pop out under the elastic force of the spring 21 and move together with the moving rod 18 and the sleeve 12. During the movement of the sleeve 12, the sealing plate 19 will press against the surface of the blocking ball 8 inside the water dispenser body 1, causing the blocking ball 8 to temporarily fall off from the outside of the water dispenser body 1. At this time, under the action of water pressure, the outside water is injected into the water dispenser body 1 through the water inlet ring 2 and distributed into the inner cavity of the sealing plate 19 and the sealing plate 14.

[0029] As the sealing plate 219 continues to move under the elastic force of the spring 321, it will fall off the blocking ball 8. At the same time, under the elastic force of the spring 17, the blocking ball 8 will reset and re-block the outside of the water collector body 1, forming a sealed state. At this time, under the action of the spring 321, the moving rod 18 and the sleeve 12 will cause the water in the inner cavity of the sealing plate 219 and the sealing plate 14 to flow into the collection bottle 5, thereby completing the water sample collection. This design allows the device to perform quantitative sampling of water sample volume according to needs, which greatly improves the convenience and accuracy of sampling work. It is especially suitable for application scenarios that require precise control of water sample volume, such as total phosphorus detection.

[0030] The device uses the fine-tuning mechanism of the scale block 11 to adjust the preset sampling volume of the column 10 / screw 13 from 0.1 to 1L. Rotating the scale block 11 by one division increases the capacity by 0.1L, meeting the total phosphorus detection standards such as GB 11893-89. The blocking ball 8 forms a double dynamic seal with the cooperation of spring 7 and sealing plate 19 to avoid transportation contamination. The balance system of the floating ball 17 and the counterweight 3 supports multi-depth stratified sampling within 50 meters, significantly improving the accuracy of total phosphorus monitoring data in lake / river profiles. At the same time, the elastic force of spring 7 is less than that of spring 20, and the elastic force of spring 20 is less than that of spring 31, thus ensuring the normal operation of the device.

[0031] Working principle: First, the collection bottle 5 is installed at the connecting ring 4 through the threaded groove structure. Then, the pull rod 6 is compressed so that the pull rod 6 is engaged with the claw 15 at the connecting block 22. The claw 15 is engaged with the pull rod 6 by the second spring 20 to achieve the effect of fixing it. Then, the adjusting column 10 is rotated according to the scale groove at the scale block 11 so that the screw 13 drives the moving rod 18 to move in the sleeve 12, thereby shortening the distance between the second sealing plate 19 and the first sealing plate 14, thereby reducing the volume cavity formed by the first sealing plate 14 and the second sealing plate 19 in the water dispenser body 1.

[0032] After the device is thrown into the water, the weight of the counterweight 3 causes the water collector body 1 to sink into the water. Simultaneously, based on the length of the traction rope 16 and the buoyancy of the float 17, the buoyancy generated by the float 17 causes the pawl 15 to retract relatively through the traction rope 16. This causes the pull rod 6 to pop out under the elastic force of the spring 21, moving along with the moving rod 18 and the sleeve 12. As the sleeve 12 moves, the sealing plate 19 presses tightly against the surface of the blocking ball 8 inside the water collector body 1, causing the blocking ball 8 to briefly detach from the outside of the water collector body 1. This allows external water to be forced through the water under pressure. Water is pumped into the water collector body 1 by the inlet ring 2 and distributed into the inner cavities of sealing plate 2 19 and sealing plate 14. As sealing plate 2 19 moves continuously under the elastic force of spring 3 21, it falls off from the blocking ball 8. Under the elastic force of spring 1 7, it drives the blocking ball 8 to reset and block the outside of the water collector body 1 to form a seal. Under the action of spring 3 21, the moving rod 18 and the sleeve 12 allow the water contained in sealing plate 2 19 and sealing plate 14 to flow into the collection bottle 5, thereby completing the water sample collection. This makes it convenient to quantitatively sample water according to the required amount, thus improving the convenience of the sampling work.

[0033] 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.
