Description

Technical Field

[0001] This utility model relates to the field of sampler technology, and in particular to a river water treatment sampler. Background Technology

[0002] With the continuous acceleration of industrialization, large amounts of wastewater discharged from various chemical plants during production processes are directly discharged into rivers without adequate treatment, resulting in a sharp increase in the concentration of heavy metals, organic matter, and harmful chemicals in the water, which seriously damages the river ecosystem. In order to effectively monitor and control river pollution and protect water resources and the ecological environment, river water samples are collected regularly to analyze the types and concentrations of pollutants.

[0003] Application No. 202420977865.2 discloses a sewage sampling device for sewage treatment, relating to the field of sewage sampling technology. This utility model includes a trolley with two symmetrical supports fixedly connected to its upper surface. A common winding shaft is rotatably connected to one side of the two supports, which are close to each other. A pull rope is wound around the arc surface of the winding shaft, and a sampler is fixedly connected to one end of the pull rope. A solenoid valve is fixedly connected to one side of the sampler. A guide wheel is rotatably connected to the upper surface of the trolley via a support rod, and the pull rope is located on the guide wheel. An observation device is provided at one end of the winding shaft, comprising a circular plate fixedly connected to the end of the winding shaft that passes through the supports. This utility model, through the observation device, facilitates accurate positioning of the sampler's depth in the sewage by the operator, enabling sampling of sewage at a fixed depth and improving the practicality of the sampler.

[0004] The above-mentioned solution has shortcomings in use. Since the water flow speed may gradually increase from the bank to the center, the distribution of pollutants may also be uneven. When adjusting the sampler to sample different locations in the river, the entire device needs to be moved, which is troublesome and will affect the efficiency of river water sampling. Therefore, we provide a river water treatment sampler. Utility Model Content

[0005] This utility model provides a river water treatment sampler that can quickly adjust the sampling position of river water in the river channel, further improving the sampling efficiency of river water.

[0018] Beneficial effects:

[0019] 1. The adjustable components allow for easy adjustment of the sampling tube's position within the river channel, enabling rapid water sampling from different locations and improving the tube's flexibility during sampling. This further enhances the efficiency of river water sampling. The sealing components allow for flexible sealing of the sampling tube's inlet, effectively preventing premature water ingress during entry into the river.

[0029] 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.

[0030] First Embodiment

[0031] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 With appendix Figure 5 As shown: A river water treatment sampler includes a base 1, a winding mechanism 2 disposed above the base 1, a connecting rope 3 disposed on the winding mechanism 2, a sampling tube 4 disposed at the other end of the connecting rope 3, and a water inlet 5 opened on the outside of the sampling tube 4. The winding mechanism 2 can be used to wind and expand the connecting rope 3, so that the sampling tube 4 can fall into the river water at different depths, and the winding mechanism 2 can be used to neatly wind the connecting rope 3.

[0032] A set of sleeve blocks 9 are installed on both the front and back of the base 1. Each sleeve block 9 has a conical insert rod 10 inside. The cooperation between the sleeve block 9 and the conical insert rod 10 can stabilize the base 1.

[0033] Adjustment component 6 is located above base 1 and includes a U-shaped frame 601 located below connecting rope 3 and a first pulley 602 located inside the U-shaped frame 601. The first pulley 602 can support the connecting rope 3, so that the sampling tube 4 is located below the first pulley 602. When the sampling tube 4 falls to collect water, it will pull the connecting rope 3 to expand and contract. At the same time, when the connecting rope 3 is wound up, it will smoothly drive the sampling tube 4 to the top.

[0034] An adjustment structure is located outside the U-shaped frame 601. The adjustment structure of the adjustment component 6 includes a support frame 603 located outside the U-shaped frame 601. A motor 604 is mounted on the inner side of the support frame 603. A threaded rod 605 is mounted on the output end of the motor 604. The other end of the threaded rod 605 extends into the U-shaped frame 601, and the threaded rod 605 is threadedly connected to the U-shaped frame 601. Using the operation of the motor 604, the threaded rod 605 rotates on the U-shaped frame 601, which in turn drives the first pulley 602 to move gradually. Simultaneously, the operator loosens the connecting rope 3. A pulley 602 will pull the connecting rope 3 and the sampling cylinder 4 to move synchronously, thereby quickly adjusting the sampling position of the sampling cylinder 4. The front and rear sides of the U-shaped frame 601 are provided with sliding grooves 606. The two sliding grooves 606 are slidably connected to the support plate 607. The front and rear ends of the support plate 607 are connected to the inner side of the U-shaped frame 601. The other end of the threaded rod 605 is rotatably connected to one side of the support plate 607. The support plate 607 can not only support and reinforce the other end of the threaded rod 605, but also support the protruding U-shaped frame 601, thereby ensuring the stability of its support for the sampling cylinder 4.

[0035] The adjustment structure of the adjustment component 6 also includes a set of guide rods 610 installed on the upper surface of the base 1. Each guide rod 610 is slidably connected to a set of connecting plates 611. The top of each connecting plate 611 is connected to the outer surface of the support frame 603. By pushing the support frame 603, the connecting plate 611 will slide on the guide rod 610, thereby quickly adjusting the position of the sampling cylinder 4 and improving the sampling efficiency.

[0036] The support frame 603 is fixedly connected to the front and rear sides with the frame plate 608. The two frame plates 608 are installed with the second pulley 609 on the side that is close to each other. The second pulley 609 is located below the connecting rope 3, which can form a stable support for the connecting rope 3, ensuring that the connecting rope 3 runs smoothly during the scaling process and avoiding jamming or damage caused by friction or entanglement. This allows the operator to more easily control the lifting and lowering of the sampling cylinder 4.

[0037] Second Embodiment

[0038] As attached Figure 1 With appendix Figure 6As shown: The sealing component 7, located inside the sampling cylinder 4, is used to seal the water inlet 5 to facilitate water sampling from different water layers. The sealing component 7 includes a miniature electric actuator 701 installed inside the sampling cylinder 4. A sealing plug 702 is installed at the telescopic end of the miniature electric actuator 701. The sealing plug 702 is located inside the water inlet 5. First, the retraction time of the miniature electric actuator 701 is adjusted using the control panel. When the sampling cylinder 4 descends to the sampling water layer, the miniature electric actuator 701 retracts, and the sealing plug 702 slides out from inside the water inlet 5, allowing river water to enter the sampling cylinder 4, thus achieving the desired water sampling effect. When sampling a specific water layer, the miniature electric actuator 701 will extend when its retraction time reaches the set time. The sealing plug 702 will then seal the water inlet 5, preventing the river water from submerging the miniature electric actuator 701 and causing it to be damaged. The sealing assembly 7 also includes a filter cover 703 located outside the sampling cylinder 4. The diameter of the filter cover 703 is larger than that of the water inlet 5. The filter cover 703 can be used to perform preliminary filtration of the river water entering the sampling cylinder 4, effectively intercepting suspended particles, algae, silt and other impurities in the water, preventing impurities from clogging the water inlet 5, thereby ensuring the normal operation of the sampling cylinder 4.

[0039] A water outlet 11 is provided at the bottom of the outer surface of the sampling tube 4. A rubber stopper 12 is installed inside the water outlet 11. When the river water sampled inside the sampling tube 4 is discharged, the rubber stopper 12 is removed, and the river water will be discharged from the water outlet 11 at the bottom of the sampling tube 4, so that the staff can collect the sampled river water.

[0040] Third Embodiment

[0041] As attached Figure 1 As shown: A counterweight 8 is installed at the bottom of the sampling tube 4. The counterweight 8 is a steel block. The counterweight 8 can increase the gravity of the sampling tube 4, which can ensure that the sampling tube 4 descends in a vertical posture in the river water, effectively preventing the sampling tube 4 from tilting or overturning, and ensuring that the sampling tube 4 can take normal samples of the river water after reaching the predetermined depth.

[0042] Working principle: When it is necessary to adjust the sampling position of the sampling cylinder 4 in the river, the motor 604 is started, the threaded rod 605 will rotate on the U-shaped frame 601, and the U-shaped frame 601 will drive the first pulley 602 to move gradually. Then, the staff will loosen the connecting rope 3 at the same time, and the first pulley 602 will pull the connecting rope 3 and the sampling cylinder 4 to move synchronously. At the same time, the staff can push the support frame 603 to move on the guide rod 610 to further adjust the position of the sampling cylinder 4, so as to facilitate the staff to take water from different positions and improve the sampling efficiency.

[0043] After the sampling cylinder 4 falls into the water, the descent distance of the connecting rope 3 can be adjusted so that the sampling cylinder 4 is at the corresponding sampling water layer. Then, the miniature electric push rod 701 is controlled to retract, and the sealing plug 702 will slide out from the water inlet 5, allowing river water to enter the sampling cylinder 4. Immediately afterwards, the miniature electric push rod 701 is quickly controlled to extend, and the sealing plug 702 will seal the water inlet 5 to prevent the river water from submerging the miniature electric push rod 701 and causing it to be damaged.
