Description

Technical Field

[0001] This invention belongs to the field of farmland water conservancy engineering technology, and in particular relates to a device for cleaning irrigation canals in farmland water conservancy projects. Background Technology

[0002] In the field of farmland water conservancy projects, irrigation canals serve as crucial equipment for agricultural irrigation and drainage, enabling targeted regulation and efficient utilization of water resources while also providing functions such as drainage and ecological protection. However, over long-term use, irrigation canals accumulate various debris such as silt, weeds, straw, and plastic waste. This not only reduces the cross-sectional area of ​​the canals, lowering water conveyance and drainage efficiency, but also easily breeds mosquitoes and causes rotting and foul odors, impacting the farmland's ecological environment. Furthermore, the accumulation of debris can cause localized blockages in the canals, leading to overflows, damage to farmland, and other problems, causing inconvenience to agricultural production.

[0003] Existing commonly used canal cleaning equipment is mainly divided into two categories: manual cleaning and simple mechanical cleaning. Manual cleaning mostly involves workers using tools such as hoes, shovels, and long-handled nets to manually remove silt and debris. This is not only inefficient and labor-intensive, but also poses a safety risk due to the slippery conditions in the canals, making it unsuitable for comprehensive cleaning of long-distance, large-section canals. Existing simple mechanical cleaning devices are mostly small dredging boats or towing equipment with scrapers, which consume a lot of energy and have high cleaning costs. Another method involves using debris-blocking nets to intercept debris in the canals, but this is prone to clogging and requires frequent manual cleaning. This increases the workload; moreover, most mechanical cleaning devices only have a single cleaning function and cannot simultaneously sample and test the water and silt in the canal, requiring additional sampling equipment, which is cumbersome and increases operating costs; the cleaning direction adjustment is not flexible enough, mostly fixed direction or single-dimensional movement, making it difficult to adapt to the cleaning needs of different canal structures such as straight canals, curved canals, and canal openings with varying widths; in addition, after cleaning debris, existing devices cannot compress and dehydrate the debris, and the cleaned debris carries a large amount of mud and water, increasing the transportation weight, raising transportation costs, and easily causing secondary pollution.

[0004] To address the shortcomings of the existing technologies, it is necessary to design a compact, stable, functionally integrated, and easy-to-operate irrigation canal cleaning device for farmland irrigation projects, so as to improve canal cleaning efficiency, reduce operating costs, and meet the needs of farmland irrigation project canal maintenance. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a farmland irrigation project water channel cleaning device, which at least partially solves the above technical problems.

[0006] The technical solution adopted in this invention is as follows: a farmland water conservancy project water channel cleaning device, including an installation plate, a fixed rod installed on the installation plate, an adjustment component movably installed on the fixed rod, a first cleaning component and a second cleaning component movably installed on the adjustment component, the first cleaning component and the second cleaning component being symmetrically installed on the adjustment component; The first cleaning component and the second cleaning component have the same structure. The first cleaning component includes a telescopic component, a cleaning component, and a collection component. A plug rod is installed on the telescopic component of the first cleaning component, and a sleeve rod is installed on the telescopic component of the second cleaning component. Both the plug rod and the sleeve rod are movably assembled to the adjustment component, and the plug rod is movably sleeved inside the sleeve rod. The cleaning component is connected to the bottom wall of the telescopic component, and the collection component is movably installed on the cleaning component.

[0007] The telescopic assembly includes a fixed sleeve, a telescopic sleeve, and a first hydraulic rod. The fixed sleeve is a hollow structure with one open end. The fixed sleeve on the first cleaning assembly is connected to the insertion rod, and the fixed sleeve on the second cleaning assembly is connected to the sleeve rod. The fixed end of the first hydraulic rod is installed on the inner side of the fixed sleeve away from the open end, and the movable end extends in the direction of the opening. The telescopic sleeve is provided in multiple sets, forming a multi-level nested structure. Except for the innermost telescopic sleeve, the other sets of telescopic sleeves are hollow structures with one open end. The sets of telescopic sleeves are nested and assembled in sequence. The outermost telescopic sleeve is movably assembled in the fixed sleeve and can extend outward. The inner adjacent telescopic sleeve is movably assembled in the outer telescopic sleeve and can extend outward. They are nested and linked in this way. The movable end of the first hydraulic rod passes through each of the outer telescopic sleeves in sequence and is fixedly connected to the innermost telescopic sleeve to drive all telescopic sleeves to extend and retract synchronously.

[0008] As a preferred embodiment of the present invention, a first groove is provided at the center of the bottom wall of the fixed sleeve. Except for the innermost telescopic sleeve, a corresponding groove is provided at the center of the bottom wall of each group of telescopic sleeves on the outer side. Each group of grooves is arranged to pass through the axial direction of the corresponding component and is positioned accordingly, thus forming an assembly channel for the cleaning component.

[0009] Preferably, the number of cleaning components and telescopic sleeves are the same, and they correspond one-to-one and are linked. The cleaning component corresponding to the outer telescopic sleeve passes through the first sliding groove and is movably connected to the bottom wall of the outer telescopic sleeve. The cleaning component corresponding to the inner telescopic sleeve passes through the sliding grooves on all the outer telescopic sleeves and the fixed sleeve in sequence and is movably connected to the bottom wall of the corresponding inner telescopic sleeve. The assembly in this way achieves synchronous linkage.

[0010] The bottom wall of the fixed sleeve is also equipped with a third tooth condition, which is placed near the opening end of the fixed sleeve and located on the outside of the cleaning component and the side of the slide groove.

[0011] Furthermore, the cleaning component includes a connecting shaft and a cleaning net. The connecting shaft on the cleaning component corresponding to the outer telescopic sleeve passes through the first sliding groove and is movably connected to the bottom wall of the outer telescopic sleeve. The connecting shaft on the cleaning component corresponding to the inner telescopic sleeve passes through the sliding grooves on all its outer telescopic sleeves and fixed sleeves in sequence and is movably connected to the bottom wall of the corresponding inner telescopic sleeve. The lower end of each connecting shaft extends out of the bottom wall of the fixed sleeve. The cleaning net is installed at the lowest end of the connecting shaft. A third gear is installed on the connecting shaft. The third gear is located outside the fixed sleeve. During the stretching or compression of the telescopic rod, the third gear on the cleaning component can mesh with the third gear, causing the cleaning component to rotate 90 degrees in both directions, thereby changing the opening direction of the cleaning net.

[0012] The collection assembly includes connecting rings and collection components. The number of connecting rings corresponds to the number of connecting shafts, and each connecting ring is movably mounted on the corresponding connecting shaft and positioned between the third gear and the cleaning net. The collection component connects two adjacent sets of connecting rings. The collection component is made of elastic material and has a hollow internal structure. A collection tube is installed at the lower end of the collection component, and the collection tube is connected to the bottom wall of the collection component. A switch is installed at the connection between the collection component and the collection tube to control the connection state between the collection component and the collection tube. The collection tube is positioned between two adjacent sets of cleaning nets.

[0013] In a preferred embodiment of the present invention, a first gear is installed on the outer wall of the insertion rod, and a second gear is installed on the outer wall of the sleeve rod, wherein both the first gear and the second gear are located within the adjustment assembly.

[0014] The adjustment assembly includes a placement shell, a motor, a third hydraulic rod, a connecting frame, a first gear condition, and a second gear condition. The placement shell is movably connected to the upper end of a fixed rod via a bushing. An arc-shaped limiting block is fixedly mounted on the outer side of the upper end of the fixed rod. A limiting groove is correspondingly provided on the bottom wall of the placement shell, and the limiting block is embedded in the limiting groove. This is prior art and is not shown in the figure. The sleeve rod and the insertion rod are movably mounted on the side wall of the placement shell. The upper end of the fixed rod has a placement cavity, and the motor is installed in the placement cavity. The output end of the motor is connected to the bottom wall of the placement shell via a coupling. The fixed end of the third hydraulic rod is installed on the upper inner wall of the placement shell. The connecting frame is connected to the movable end of the third hydraulic rod. The first gear condition and the second gear condition are respectively installed at both ends of the connecting frame, and the first gear condition meshes with the first gear, and the second gear condition meshes with the second gear.

[0015] The beneficial effects of the present invention after adopting the above structure are as follows: (1) By adjusting the dual-drive structure of the components, the cleaning direction can be adjusted in two dimensions. The motor drives the cleaning components to rotate in a circular motion, expanding the cleaning coverage of the water channel. The third hydraulic rod drives the insertion rod and sleeve rod to rotate in the opposite direction, accurately adjusting the orientation of the cleaning net, which can adapt to the cleaning needs of debris in different locations such as the straight section, curved section, both sides of the channel wall, and the center of the channel bottom.

[0016] (2) The telescopic rod and the cleaning net open and close synchronously. Compared with suction and scraping cleaning, passive rotation cleaning causes less disturbance to the canal wall and bottom, does not damage the canal lining structure, and protects the original facilities of the canal.

[0017] (3) By setting the telescopic components, the telescopic amplitude and expansion range can be controlled. The degree of telescopic expansion can be flexibly adjusted according to the width, depth and debris distribution range of the water channel. It is suitable for narrow channels, wide channels, shallow channels, deep channels and different debris distribution densities. After the multi-level telescopic sleeve is fully expanded, it drives multiple sets of cleaning components to expand synchronously. With the symmetrical setting of the first and second cleaning components, the water channel cleaning area is greatly expanded. Compared with the existing device, it can efficiently complete the debris cleaning of long-distance and large-section water channels, significantly improving the work efficiency. At the same time, by using the telescopic expansion action of the telescopic components, the cleaning components are rotated 90 degrees synchronously through the meshing of the third gear and the third tooth condition, realizing the telescopic expansion and opening and closing at the same time. No additional drive components are needed to control the opening and closing of the cleaning net bucket, simplifying the device structure.

[0018] (4) During the retraction process, the multi-level telescopic sleeves are nested and retracted into the fixed sleeve, which greatly reduces the space occupied by the device and facilitates operation and equipment storage in narrow water channels. At the same time, each group of cleaning nets approaches and squeezes each other, compressing the silt, weeds, garbage and other debris captured between the cleaning nets, efficiently squeezing out the mud and water carried inside the debris, reducing the weight of debris transportation, reducing transportation costs, further improving work efficiency, and also reducing debris falling during the retraction process, further improving cleaning reliability.

[0019] (5) The collection component and the cleaning component are linked. The negative pressure is automatically generated by the stretching / compression action of the telescopic component, so as to achieve efficient sampling, sealing and discharge of water samples in the canal. No additional sampling equipment is required, which simplifies the operation process and reduces the operating cost. At the same time, the collection pipes of the first and second cleaning components have different lengths, which can be adapted to the water sampling needs of different depths in the canal.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0025] like Figures 1-9 As shown, a farmland irrigation canal cleaning device includes an installation plate 1. A counterweight is fixed to the bottom of the installation plate 1, and multiple sets of anchor bolts are installed through it. The anchor bolts are inserted into the bottom layer to achieve fixation, adapting to different bottom environments and ensuring stable installation of the device. A fixing rod 2 is installed on the installation plate 1, and an adjustment component 3 is movably installed on the fixing rod 2. A first cleaning component 4 and a second cleaning component 5 are movably installed on the adjustment component 3. The first cleaning component 4 and the second cleaning component 5 are symmetrically installed on the adjustment component 3. The first cleaning component 4 and the second cleaning component 5 have the same structure. The first cleaning component 4 includes a telescopic component 6, a cleaning component 7, and a collecting component 8. A rod 9 is installed on the telescopic component 6 of the first cleaning component 4, and a sleeve rod 10 is installed on the telescopic component 6 of the second cleaning component 5. Both the rod 9 and the sleeve rod 10 are movably assembled to the adjusting component 3, and the rod 9 is movably sleeved inside the sleeve rod 10. The cleaning component 7 is connected to the bottom wall of the telescopic component 6, and the collecting component 8 is movably installed on the cleaning component 7.

[0026] The telescopic component 6 includes a fixed sleeve 11, a telescopic sleeve 12, and a first hydraulic rod 13. The fixed sleeve 11 is a hollow structure with one end open. The fixed sleeve 11 on the first cleaning component 4 is connected to the insertion rod 9, and the fixed sleeve 11 on the second cleaning component 5 is connected to the sleeve rod 10. The fixed end of the first hydraulic rod 13 is installed on the inner side of the fixed sleeve 11 away from the open end, and the movable end extends in the direction of the opening. The telescopic sleeve 12 is provided in multiple sets, forming a multi-level nested structure. Except for the innermost telescopic sleeve 12, the other sets of telescopic sleeves 12 are hollow structures with one open end. The sets of telescopic sleeves 12 are nested and assembled in sequence. The outermost telescopic sleeve 12 is movably assembled in the fixed sleeve 11 and can extend outward. The inner adjacent telescopic sleeves 12 are movably assembled in the outer telescopic sleeve 12 and can extend outward. They are nested and linked in this way. The movable end of the first hydraulic rod 13 passes through each of the outer telescopic sleeves 12 in sequence and is fixedly connected to the innermost telescopic sleeve 12 to drive all the telescopic sleeves 12 to extend and retract synchronously. It should be noted that the inner wall of the fixed sleeve 11 is provided with a guide groove along the axial direction, and the outermost telescopic sleeve 12 has a corresponding guide block on its outer wall. The guide block slides into the guide groove. Each set of telescopic sleeves 12 has a fixed limiting ring at its open end, and the inner adjacent telescopic sleeves 12 have a corresponding limiting boss at their ends. The limiting boss abuts against the limiting ring to achieve telescopic limiting. Through the cooperation of the guide groove and the guide block, the multi-stage telescopic sleeves 12 are ensured to telescopically extend and retract precisely, ensuring stable meshing between the third gear 18 and the third gear condition 15.

[0027] The bottom wall of the fixed sleeve 11 is provided with a first groove 14. Except for the innermost telescopic sleeve 12, the bottom wall of each group of telescopic sleeves 12 on the outer side is provided with a corresponding groove. Each group of grooves is provided through the axial direction of the corresponding component and is positioned accordingly, thus forming the assembly channel of the cleaning component 7.

[0028] The number of cleaning components 7 and telescopic sleeves 12 are the same and they correspond one-to-one and are linked. The cleaning component 7 corresponding to the outer telescopic sleeve 12 passes through the first slide groove 14 and is movably connected to the bottom wall of the outer telescopic sleeve 12. The cleaning component 7 corresponding to the inner telescopic sleeve 12 passes through the slide grooves on all the outer telescopic sleeves 12 and the fixed sleeve 11 in sequence and is movably connected to the bottom wall of the corresponding inner telescopic sleeve 12. The assembly is synchronized and linked in this way. It should be noted that when the telescopic assembly 6 is working, the first hydraulic rod 13 extends to push the innermost telescopic sleeve 12 outward, thereby sequentially driving each group of telescopic sleeves 12 on the outside to extend in conjunction, so that the telescopic assembly 6 is in a fully stretched state; when the first hydraulic rod 13 retracts, it pulls the innermost telescopic sleeve 12 back, thereby driving each group of telescopic sleeves 12 to retract into the fixed sleeve 11, completing the reset.

[0029] The bottom wall of the fixed sleeve 11 is also equipped with a third tooth condition 15, which is placed near the opening end of the fixed sleeve 11 and located on the outside of the cleaning component 7 and the side of the slide groove.

[0030] The cleaning component 7 includes a connecting shaft 16 and a cleaning net 17. The connecting shaft 16 on the cleaning component 7 corresponding to the outer telescopic sleeve 12 passes through the first sliding groove 14 and is movably connected to the bottom wall of the outer telescopic sleeve 12. The connecting shaft 16 on the cleaning component 7 corresponding to the inner telescopic sleeve 12 passes through the sliding grooves on all the outer telescopic sleeves 12 and the fixed sleeve 11 in sequence and is movably connected to the bottom wall of the corresponding inner telescopic sleeve 12. The lower end of the connecting shaft 16 extends out of the bottom wall of the fixed sleeve 11. The cleaning net 17 is installed at the lowest end of the connecting shaft 16. A third gear 18 is installed on the connecting shaft 16. The third gear 18 is located outside the fixed sleeve 11. During the stretching or compression of the telescopic rod, the third gear 18 on the cleaning component 7 can mesh with the third gear condition 15, driving the cleaning component 7 to rotate 90 degrees in both directions, thereby changing the opening direction of the cleaning net 17. It should be noted that when the telescopic assembly 6 is working, the first hydraulic rod 13 extends to push the innermost telescopic sleeve 12 outward. When the innermost telescopic sleeve 12 moves the cleaning component 7 on it to the position of the third tooth condition 15, the third gear 18 on the cleaning component 7 meshes with the third tooth condition 15, causing the cleaning component 7 to rotate 90 degrees and adjust the opening of the cleaning net 17. The innermost telescopic sleeve 12 sequentially drives each of its outer telescopic sleeves 12 to extend in conjunction. During the extension process, the third gear 18 meshes with the third tooth condition 15, causing the cleaning component 7 to rotate 90 degrees sequentially and adjust the opening of the cleaning net 17. When the first hydraulic rod 13 retracts, it pulls the innermost telescopic sleeve 12 back, thereby causing each of the telescopic sleeves 12 to retract into the fixed sleeve 11, completing the reset. During this process, the third gear 18 on the cleaning component 7 meshes with the third tooth condition 15 again, causing the cleaning component 7 to rotate 90 degrees in the opposite direction and adjust the opening of the cleaning net 17 again.

[0031] The collection component 8 includes connecting rings 19 and collection parts 20. The number of connecting rings 19 is the same as that of connecting shafts 16, and they correspond one-to-one. The connecting rings 19 are movably installed on the corresponding connecting shafts 16 and are located between the third gear 18 and the cleaning net 17. The collection parts 20 connect two adjacent sets of connecting rings 19. The collection parts 20 are made of elastic material and have a hollow internal structure. A collection tube 21 is installed at the lower end of the collection parts 20. The collection tube 21 is connected to the bottom wall of the collection parts 20. A switch is installed at the connection between the collection parts 20 and the collection tube 21 to control the connection state between the collection parts 20 and the collection tube 21. The collection tube 21 is located between two adjacent sets of cleaning nets 17. It should be noted that the length of the collection tube 21 on the first cleaning component 4 and the length of the collection tube 21 on the second cleaning component 5 are different, in order to adapt to the water sample collection needs at different depths of the canal. When the telescopic sleeve 12 is in a stretched state, the connecting shaft 16 stretches the collecting component 20 through the connecting ring 19. At this time, the switch is in the closed state, the internal volume of the collecting component 20 increases, and the pressure decreases. When it is necessary to sample the cleaned water channel, the switch is opened, and the negative pressure inside the collecting component 20 draws the water in the channel through the collecting pipe 21. After sampling is completed, the switch is closed, and the sample is sealed. When the telescopic component 6 is in a compressed state, the collecting component 20 is released from the stretched state, and the collecting component 20 containing the sample is in a bulging state. When the staff takes a sample, the switch is opened, and the sample inside the collecting component 20 is discharged through the collecting pipe 21, completing the sample collection.

[0032] A first gear 22 is installed on the outer wall of the insertion rod 9, and a second gear 23 is installed on the outer wall of the sleeve rod 10. Both the first gear 22 and the second gear 23 are located within the adjustment assembly 3. The adjustment assembly 3 includes a placement shell 24, a motor 25, a third hydraulic rod 26, a connecting frame 27, a first gear condition 28, and a second gear condition 29. The placement shell 24 is movably connected to the upper end of the fixed rod 2 via a bushing. An arc-shaped limiting block is fixedly installed on the outer side of the upper end of the fixed rod 2. A limiting groove is correspondingly provided on the bottom wall of the placement shell 24, and the limiting block is embedded in the limiting groove. This is prior art and is not shown in the figure. The sleeve rod 10 and the insertion rod 9 are respectively movably installed on the side wall of the placement shell 24. The upper end of the fixed rod 2 is provided with a placement cavity. The motor 25 is installed in the placement cavity. The output end of the motor 25 is connected to the bottom wall of the placement shell 24 through a coupling. The fixed end of the third hydraulic rod 26 is installed on the inner upper wall of the placement shell 24. The connecting frame 27 is connected to the movable end of the third hydraulic rod 26. The first tooth condition 28 and the second tooth condition 29 are respectively installed at both ends of the connecting frame 27. The first tooth condition 28 meshes with the first gear 22, and the second tooth condition 29 meshes with the second gear 23. It should be noted that the operation of motor 25 can drive the placement shell 24 to rotate. The placement shell 24 drives the first cleaning component 4 and the second cleaning component 5 to rotate through the insertion rod 9 and the sleeve rod 10. The operation of the third hydraulic rod 26 pushes the connecting frame 27 to move. The connecting frame 27 drives the first tooth condition 28 and the second tooth condition 29 to move. The first tooth condition 28 drives the insertion rod 9 to rotate through the first gear 22. The second tooth condition 29 drives the sleeve rod 10 to rotate in the opposite direction through the second gear 23. The insertion rod 9 drives the first cleaning component 4 to rotate. The sleeve rod 10 drives the second cleaning component 5 to rotate in the opposite direction, which can adjust the cleaning direction of the cleaning net 17.

[0033] The specific usage is as follows: First, the device is fixed to the bottom of the target water channel by the counterweight block at the bottom of the mounting plate 1 and multiple sets of anchor bolts that run through it, ensuring that the device does not shake or shift during subsequent operations. The telescopic component 6 is placed on the water surface, the lower end of the cleaning net 17 is placed in the water and the upper end is exposed above the water surface, and the lower end of the collection pipe 21 is placed in the water.

[0034] The first hydraulic rod 13 of the control telescopic assembly 6 extends, pushing the innermost telescopic sleeve 12 outward. The limiting boss at the end of the innermost telescopic sleeve 12 abuts against the limiting ring on the inner wall of the opening end of the adjacent outer telescopic sleeve 12, thereby driving the outer telescopic sleeve 12 to extend. In this way, all the multi-stage telescopic sleeves 12 extend in sequence, so that the telescopic assembly 6 is in a fully stretched state. During the unfolding of the telescopic sleeve 12, the third tooth condition 15 on the bottom wall of the fixed sleeve 11 meshes with the third gear 18 on each group of cleaning parts 7 in sequence, driving the cleaning parts 7 to rotate 90 degrees and adjusting the opening direction of the cleaning net 17.

[0035] The third hydraulic rod 26 is activated, which pushes the connecting frame 27 to move. The connecting frame 27 drives the first tooth condition 28 and the second tooth condition 29 at both ends to move synchronously. The first tooth condition 28 drives the insert rod 9 to rotate through the first gear 22, and the second tooth condition 29 drives the sleeve rod 10 to rotate in the opposite direction through the second gear 23. This, in turn, drives the first cleaning component 4 and the second cleaning component 5 to rotate in the opposite direction, aligning with the distribution position of debris in the water channel and adjusting the cleaning direction.

[0036] Then, the motor 25 is started. The output end of the motor 25 drives the placement shell 24 to rotate through the coupling. The placement shell 24 drives the first cleaning component 4 and the second cleaning component 5 to rotate in a circular motion through the insertion rod 9 and the sleeve rod 10, so as to comprehensively grab and clean up weeds, straw, plastic waste and other debris in the ditch.

[0037] After the debris is cleared, the first hydraulic rod 13 is continuously contracted, causing the multi-stage telescopic sleeve 12 to retract into the fixed sleeve 11. During the retraction, the cleaning nets 17 move closer and squeeze each other, compressing the debris captured between the cleaning nets 17 and efficiently squeezing out the mud and water carried inside the debris, reducing the weight of the debris during transport. At the same time, during the retraction, the third gear 18 on the cleaning component 7 meshes with the third gear condition 15 again, causing the cleaning component 7 to rotate 90 degrees in the opposite direction, realizing the reset of the opening of the cleaning net 17 and reducing the amount of debris falling during the retraction. After the telescopic sleeve 12 is fully retracted and the debris is compressed, all power components are turned off to complete the device reset, and the staff can then remove the debris.

[0038] When the telescopic sleeve 12 is fully stretched, the connecting shaft 16 stretches the collecting component 20 through the connecting ring 19. At this time, the switch at the connection between the collecting component 20 and the collecting pipe 21 is closed. The internal volume of the collecting component 20 increases and the pressure decreases, resulting in a stretched and unfolded state. When it is necessary to sample the corresponding cleaned water channel, the switch is opened, and the negative pressure inside the collecting component 20 draws the water in the water channel through the collecting pipe 21. After sampling, the switch is closed to seal the sample. Then, the first hydraulic rod 13 is controlled to retract, and the telescopic sleeve 12 is nested back into the fixed sleeve 11. The collecting component 20 is reset and bulges under the reset action of its own highly elastic material. When the staff opens the switch, the sample inside the collecting component 20 can be discharged through the collecting pipe 21, completing a single sampling.

[0039] The sampling method is as follows: Keeping the expansion range of the telescopic sleeve 12 unchanged and the position of the third hydraulic rod 26 unchanged, the cleaning component is rotated as a whole by the motor 25. After switching to the set sampling position, the switches on the collection component 8 are turned on in sequence, and the basic sampling operation is repeated. Keeping the expansion range of the telescopic sleeve 12 unchanged, the direction is adjusted by the third hydraulic rod 26, thereby changing the sampling depth. The cleaning position is changed by rotating the motor 25. Switching to different sampling positions, the switches on the collection component 8 are turned on in sequence, and the basic sampling operation is repeated. The expansion range of the telescopic sleeve 12 can also be adjusted to achieve sampling at different locations.

In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the invention, such designs should fall within the protection scope of the present invention.
