Description

Technical Field

[0001] This invention relates to the field of water pollution detection equipment, and more particularly to a mechanical device for continuous water pollution detection with a self-cleaning function. Background Technology

[0002] Water pollution detection, also known as water quality monitoring, is a technical process that uses physical, chemical, and biological methods to qualitatively and quantitatively determine the types, concentrations, and trends of pollutants in water bodies such as rivers, lakes, seas, groundwater, and industrial wastewater. This results in the evaluation of water environmental quality and provides data support for pollution prevention and control and water resource management. Its core monitoring indicators cover temperature, pH, dissolved oxygen, turbidity, chemical oxygen demand (COD), ammonia nitrogen, heavy metals, and microorganisms. It is a fundamental and crucial task for water environment governance, drinking water safety, and ecological protection. Throughout the water pollution detection process, sampling is a critical step that determines the accuracy and reliability of the test results. The representativeness, purity, and integrity of the water sample directly affect the authenticity and validity of subsequent indicator analyses. Problems such as sample contamination or depth deviation during sampling will directly lead to distorted test data.

[0003] Existing water pollution detection devices are prone to clogging of their sampling mechanisms by suspended impurities and aquatic plants during long-term use, leading to poor water intake, affecting the continuity of detection work, and impacting the efficiency of water pollution detection. This is especially true in the treatment of flowing water, such as river water and other outdoor water sources, where the inability to conveniently and continuously sample directly affects the continuous detection and comparison of samples. In addition, pollutants easily adhere to the inner wall of the sampling pipe, and long-term accumulation can contaminate subsequent water samples, resulting in inaccurate test results. Existing devices lack effective self-cleaning functions and cannot promptly remove deposits from the inner wall of the pipe. Furthermore, the sampling mechanisms of existing detection devices are mostly fixed-depth sampling devices, which cannot flexibly adjust the sampling depth according to detection needs. When sampling at different depths is required, water samples obtained outdoors on the shore are easily contaminated, and manual sampling is difficult and poses safety hazards. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a self-cleaning mechanical device for continuous water pollution detection. This addresses the issue that existing water pollution detection devices are prone to clogging of their water intake mechanisms by suspended impurities and aquatic plants, resulting in poor water intake and affecting the continuity and efficiency of detection. This is particularly problematic in outdoor water treatment, such as river water, where convenient and continuous sampling is difficult, hindering continuous comparison of water samples. Furthermore, pollutants easily adhere to the inner wall of the water intake pipe, and long-term accumulation can contaminate subsequent water samples, leading to distorted test results. Existing devices lack effective self-cleaning capabilities and cannot promptly remove deposits from the inner wall. In addition, existing sampling mechanisms mostly use fixed-depth sampling, making it difficult to flexibly adjust the sampling depth as needed. Sampling at different depths on outdoor shorelines can easily cause water contamination, while manual entry into the water is difficult to operate and poses safety hazards.

[0005] To address the aforementioned problems, the present invention is implemented through the following technical solution.

The angle between the first and second oblique nozzles and the branch water guide pipe is 30-45°, and the spray angles of the first and second oblique nozzles are opposite. Multiple sets of the first and second oblique nozzles are arranged at equal intervals along the axial direction of the outside of the branch water guide pipe.

[0012] In one embodiment, the auxiliary mobile fixed-point sampling mechanism includes a fixed frame, a rotating shaft, a rotating limiting disk, a fixed block, a limiting rod, an insertion hole, a connecting strip, a scale, a connecting rod, an auxiliary submersible block, a pulley, a mounting threaded hole, a fixed slide, and a slide groove. The bottom of the fixed frame is welded and fixed to the upper end of the frame. The fixed frame is U-shaped. The rotating shaft is provided on the inner side of the fixed frame, and the rotating limiting disk is provided in the middle of the rotating shaft. The connecting strip is wrapped around the outer side of the rotating limiting disk in an annular shape.

[0016] This invention provides a mechanical device for continuous water pollution detection with self-cleaning function. Compared with the prior art, it has the following advantages: 1. The continuous water intake mechanism enables uninterrupted sampling of outdoor flowing water such as river water or other water resources, ensuring continuous testing; the wavy barrier mesh increases the effective interception area compared to the flat mesh, which can effectively block aquatic plants and suspended impurities, and the undulating surface is not easy to trap debris, greatly reducing the probability of adsorption and clogging; combined with the adjustable support structure, it avoids contact with bottom silt, and can be used for a long time without clogging or interruption, significantly improving the testing stability and efficiency of complex water areas such as outdoor areas; 2. The self-cleaning mechanism adopts a reverse oblique tangential spray design. The oblique nozzle one and oblique nozzle two form a 30-45° bidirectional rinsing, which has a larger coverage area and stronger peeling force compared with the forward direct spray rinsing. The jet is reflected by the pipe wall to form a secondary turbulent cleaning, which can thoroughly remove the contaminants attached to the inner wall of the pipe, avoid secondary contamination of the sample, and ensure the accuracy and consistency of data in long-term continuous testing. 3. The auxiliary mobile fixed-point sampling mechanism can freely set and lock the sampling depth through scales and limit structures to meet the needs of different water layers. With the help of pulleys and carriage guides, the sampling component sinks smoothly and without deviation, solving the problems of fixed sampling depth and partial data in traditional devices, and realizing full-depth stratified sampling. The automatic sampling component adopts a hydraulically driven telescopic cover plate and an arc-shaped sealing gasket. After sampling, it automatically closes and seals. The sealing gasket is embedded in the reserved groove to form a reliable seal. During the lifting and movement process, the water sample does not leak or mix, ensuring the authenticity and validity of the water sample. Attached Figure Description

The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0031] Reference Figures 1-11 A continuous water pollution detection mechanical device with self-cleaning function includes: a frame 1, a workbench 2 welded and fixed to the middle of the upper end of the frame 1, and a continuous water intake mechanism 3 provided on the upper end of the workbench 2. An anti-clogging mechanism 4 is provided at the bottom of the continuous water intake mechanism 3. The anti-clogging mechanism 4 is used to prevent clogging during the water intake process of the continuous water intake mechanism 3. A self-cleaning mechanism 5 is provided on the upper end of the workbench 2 corresponding to the side of the continuous water intake mechanism 3. An auxiliary moving fixed-point sampling mechanism 6 is provided on one side of the upper end of the frame 1. An automatic sampling component 7 is provided on one side of the auxiliary moving fixed-point sampling mechanism 6.

[0032] The continuous water intake mechanism 3 includes an inlet riser 301, a water pump 302, an outlet pipe 303, a water intake tank 304, an inlet hole 305, and a threaded connecting ring 306. One end of the water pump 302 is connected to the inlet riser 301, and the end of the water pump 302 away from the inlet riser 301 is connected to the outlet pipe 303. The water intake tank 304 is located below the outlet pipe 303 and is positioned at the corresponding position on the upper end of the frame 1. The inlet riser 301 is used to draw water from the water body, and the inlet end of the inlet riser 301 has multiple inlet holes 305. A threaded connecting ring 306 is located on the outer side of the inlet riser 301 above the inlet holes 305.

[0033] The anti-clogging mechanism 4 includes a first connecting plate 401, a second connecting plate 402, a threaded mounting ring 403, a connecting rod 404, a barrier wire 405, an adjustable screw 406, a base plate 407, and mounting screw holes 408. The first connecting plate 401 and the second connecting plate 402 are connected by the connecting rod 404, and the connecting rod 404 is distributed in a rectangular equidistant manner between the first connecting plate 401 and the second connecting plate 402.

[0034] The second connecting plate 402 has a threaded mounting ring 403 in the middle. The second connecting plate 402, through the threaded mounting ring 403 and the threaded connecting ring 306, forms a detachable structure with the water inlet riser 301. The barrier mesh wire 405 is rectangular and is welded and fixed to multiple connecting rods 404 in sequence. Multiple barrier mesh wires 405 are provided. The barrier mesh wire 405 and the connecting rods 404 form a rectangular mesh structure. The barrier mesh wire 405 is wavy. The bottom of the first connecting plate 401 has at least three adjustable screws 406 distributed in a ring at equal intervals. The bottom of the adjustable screws 406 is welded and fixed with a base plate 407. The first connecting plate 401 has a mounting screw hole 408 at the contact point with the adjustable screws 406. The adjustable screws 406 are used to adjust the relative distance between the first connecting plate 401 and the lowest point of the water intake area.

[0035] The mesh structure formed by the wavy barrier wire 405 and the connecting pole 404 can effectively block suspended impurities, aquatic plants and other debris in the water, preventing debris from entering the water inlet 305 and causing blockage, thus ensuring the normal operation of continuous water intake. Compared with a flat mesh, the wavy barrier wire 405 increases the effective interception area and can better block aquatic plants and suspended impurities; at the same time, the undulating surface is less likely to trap debris, greatly reducing the probability of impurity adsorption, thus making it more efficient at preventing blockage.

[0036] The self-cleaning mechanism 5 includes a clean water inlet pipe 501, a second water pump 502, a branch water pipe 503, a water pipe connector 504, a fixing rod 505, a first oblique nozzle 506, and a second oblique nozzle 507. The inlet end of the second water pump 502 is connected to the clean water inlet pipe 501. The outlet end of the second water pump 502 is provided with a branch water pipe 503. There are two branch water pipes 503, and the two branch water pipes 503 pass through the inlet riser 301 and the outlet pipe 303 respectively, and are set through the middle of the inlet riser 301 and the outlet pipe 303. A water pipe connector 504 is provided where the inlet riser 301 and the outlet pipe 303 pass through the branch water pipe 503.

[0037] The branch water pipe 503 extends into the water inlet riser 301 and the water outlet pipe 303. Fixing rods 505 are provided on both sides of the pipe section. Multiple sets of fixing rods 505 are provided and are arranged at equal intervals along the axial direction of the water inlet riser 301 and the water outlet pipe 303. The end of the fixing rod 505 away from the branch water pipe 503 is welded and fixed to the inner wall of the water inlet riser 301 and the water outlet pipe 303. This is used to position the branch water pipe 503 and keep it at the central axis of the pipe. The first oblique nozzle 506 and the second oblique nozzle 507 are distributed in a ring staggered manner on the outside of the branch water pipe 503. The included angle between the first oblique nozzle 506 and the second oblique nozzle 507 and the branch water pipe 503 is 30-45°. The spray angles of the first oblique nozzle 506 and the second oblique nozzle 507 are opposite. Multiple sets of oblique nozzles 506 and the second oblique nozzle 507 are provided and are arranged at equal intervals along the axial direction of the outside of the branch water pipe 503.

[0038] High-pressure clean water is sprayed onto the inner wall of the pipe through multiple sets of annular staggered nozzles 506 and 507 with opposite spray angles, achieving all-round flushing of the inner wall of the pipe. The angled nozzles 506 and 507 are arranged in opposite oblique spray directions, and the spray direction forms a tangential flushing angle with the inner wall of the pipe. Compared with the direct spray method, it can significantly increase the effective flushing coverage area and enhance the stripping effect of contaminants attached to the pipe wall. At the same time, the jet is reflected by the pipe wall to form a secondary turbulent flushing, which further improves the thoroughness of self-cleaning and avoids local residue.

[0039] The auxiliary mobile fixed-point sampling mechanism 6 includes a fixed frame 601, a rotating shaft 602, a rotating limit plate 603, a fixing block 604, a limit rod 605, an insertion hole 606, a connecting belt 607, a scale mark 608, a connecting rod 609, an auxiliary sinking block 610, a pulley 611, a mounting threaded hole 612, a fixed slide 613, and a slide groove 614. The bottom of the fixed frame 601 is welded and fixed to the upper end of the frame 1. The fixed frame 601 is U-shaped, and the rotating shaft 602 is provided on the inner side of the fixed frame 601. A rotating limiting disk 603 is provided in the middle. A connecting band 607 is wrapped around the outer side of the rotating limiting disk 603 in a ring shape. A fixing block 604 is welded and fixed on one side of the fixed frame 601. An insertion hole 606 is provided through the corresponding position of the fixing block 604 and the rotating limiting disk 603. The insertion hole 606 is used to insert a limiting rod 605. The limiting rod 605 is used to limit the rotation of the rotating limiting disk 603. The connecting band 607 is flat and has a scale mark 608 on its surface. The scale mark 608 is used to locate the sampling depth.

[0040] A connecting rod 609 is connected to one end of the connecting belt 607 away from the limiting plate 603. The connecting rod 609 is U-shaped. An auxiliary sinking block 610 is welded and fixed to the U-shaped open end of the connecting rod 609. At least two sets of pulleys 611 are symmetrically arranged on both sides of the auxiliary sinking block 610. A fixed slide 613 is wrapped around the non-opposite side of the two sets of pulleys 611. The fixed slide 613 has grooves 614 on both sides of the inner wall of the contact pulleys 611. One side of the fixed slide 613 is welded and fixed to the outer side of the water inlet riser 301. An installation threaded hole 612 is opened through the middle of the auxiliary sinking block 610.

[0041] The automatic sampling assembly 7 includes a sampling cylinder 701, a connecting screw 702, a water inlet 703, a reserved groove 704, a hydraulic rod 705, a telescopic rod 706, a telescopic cover plate 707, and an arc-shaped sealing gasket 708. The sampling cylinder 701 is provided with a connecting screw 702 on one side. The sampling cylinder 701 cooperates with the connecting screw 702 and the mounting threaded hole 612 to form a detachable structure with the auxiliary sinking block 610. The sampling cylinder 701 is cylindrical, and a water inlet 703 is provided on one side of the sampling cylinder 701.

[0042] The sampling cylinder 701 has a hydraulic rod 705 longitudinally arranged in the middle of its interior, and the driving end of the hydraulic rod 705 is provided with a telescopic rod 706. The end of the telescopic rod 706 away from the telescopic rod 706 is provided with a telescopic cover plate 707, and an arc-shaped sealing gasket 708 is bonded and fixed to the covering surface of the telescopic cover plate 707. The inner wall of the sampling cylinder 701 on the side with the water inlet 703 has a reserved groove 704 with a matching shape at the position where it matches the arc-shaped sealing gasket 708.

[0043] During use, first, fix the frame 1 in a suitable position in the detection area. Adjust the adjustable screw 406 of the anti-clogging mechanism 4 to maintain a suitable distance between the base plate 407 and the lowest point of the water intake area, preventing silt from clogging and blocking the mesh wire 405. Fix the anti-clogging mechanism 4 to the inlet end of the water inlet riser 301 through the cooperation of the threaded mounting ring 403 and the threaded connecting ring 306. Then, extend the water inlet riser 301 into the water area to be tested, so that the water inlet 305 is at the depth to be tested. Start the water pump 302. The water pump 302 draws water through the water inlet 305 of the water inlet riser 301. The water is then introduced into the water intake tank 304 through the water outlet pipe 303. The detection instrument can be placed in the water intake tank 304. This enables continuous water body monitoring. During water intake, the wavy barrier mesh 405 of the anti-clogging mechanism 4, together with the connecting rod 404, forms a mesh structure that effectively blocks suspended impurities, aquatic plants, and other debris in the water, preventing them from entering the inlet hole 305 and causing blockage. This ensures the normal operation of continuous water intake. Compared to a flat mesh, the wavy barrier mesh 405 increases the effective interception area, better blocking aquatic plants and suspended impurities. Simultaneously, the undulating surface makes it less prone to debris adhesion, significantly reducing the probability of impurity adsorption, thus achieving more efficient anti-clogging. After the continuous water intake mechanism 3 has been operating for a period of time, the second water pump 502 is activated. The second water pump 502 introduces purified water through the purified water inlet pipe 501, and the purified water flows through a branch... Water is delivered through the guide pipe 503 to the inlet riser 301 and outlet pipe 303. Multiple sets of annularly staggered, angled nozzles 506 and 507 spray high-pressure clean water onto the inner wall of the pipes, achieving comprehensive flushing and removing contaminants. The angled nozzles 506 and 507 are arranged in opposite directions, forming a tangential flushing angle with the inner wall of the pipe. Compared to direct spraying, this significantly increases the effective flushing coverage area and enhances the removal of contaminants from the pipe wall. Simultaneously, the jet is reflected by the pipe wall, creating secondary turbulent flushing, further improving self-cleaning thoroughness and preventing localized residue. After self-cleaning, turn off water pump 502 and continue continuous water sampling and testing. Determine the sampling depth according to the testing requirements, pull out the limit rod 605, rotate the limit plate 603, release the connecting belt 607, and assist the sinking block 610 to drive the sampling cylinder 701 to sink under its own weight. The pulley 611 slides in the groove 614 of the fixed slide 613 to ensure that the sampling cylinder 701 moves stably along the water inlet riser 301. Observe the sinking depth of the sampling cylinder 701 through the scale mark 608 on the surface of the connecting belt 607. When the preset sampling depth is reached, stop rotating the rotating limit plate 603, insert the limit rod 605 into the insertion hole 606, and fix the rotating limit plate 603 to fix the sampling depth.At this time, the automatic sampling component 7 is activated. Both the hydraulic rod 705 and the telescopic rod 706 are waterproof. The hydraulic rod 705 activates, driving the telescopic rod 706 to retract. The retraction of the telescopic rod 706 moves the telescopic cover 707 away from the water inlet 703, allowing water to enter the sampling cylinder 701 through the water inlet 703. After sampling, the hydraulic rod 705 is activated again, driving the telescopic rod 706 to extend, causing the telescopic cover 707 to close the water inlet 703. The arc-shaped sealing gasket 708 is embedded in the pre-reserved groove 704, achieving a seal and preventing sample leakage. Then pull out the limiting rod 605, rotate the limiting disc 603 in the opposite direction, retract the connecting belt 607, raise the sampling cylinder 701 above the water surface, disassemble the connecting screw 702, and remove the sampling cylinder 701 for further sample testing. When the anti-clogging mechanism 4 needs cleaning, rotate the threaded mounting ring 403 to remove the anti-clogging mechanism 4 from the water inlet riser 301, clean the debris on the barrier wire 405, and then reinstall and fix the anti-clogging mechanism 4 by cooperating with the threaded mounting ring 403 and the threaded connecting ring 306.
