Description

Technical Field

[0001] This invention relates to the field of river management technology, specifically to a river cleaning device and cleaning method for water conservancy projects. Background Technology

[0002] Algae, belonging to the genus Myriophyllum in the family Myriophyllumceae, are perennial aquatic plants found in ponds. They proliferate, especially in eutrophic waters. Algae grow in ponds and rice paddies across various regions. However, in ponds and rice paddies with abundant algae, the dense distribution of algae blocks sunlight, affecting the growth of phytoplankton and other photosynthetic organisms. These organisms need to produce oxygen through photosynthesis. When they die due to the algae blocking sunlight, the depleted oxygen cannot be replenished, exacerbating the oxygen deficiency problem. Insufficient dissolved oxygen in the water affects the respiration of fish, ultimately leading to their death.

[0003] To reduce the pollution and harm of algae to water bodies, workers need to clean the river channels regularly to prevent the spread of algae pollution and its impact on the surrounding environment. Existing algae management methods mostly involve mass dredging by dredging boats. However, algae contain a large amount of water, which not only occupies the carrying capacity of the boats, but also wastes water resources as the algae are usually transported to shore for treatment. Even if the water is transported back, it will increase transportation costs. In view of this, the present invention proposes a river cleaning device and cleaning method for water conservancy projects. Summary of the Invention

The middle of the rear wall of the storage compartment 11 is hinged with a movable door 19.

[0045] The cleaning method of the water conservancy engineering river cleaning device of the present invention comprises the following steps:

[0046] S1. Use the fixing frame 2 to fix the outer shell 1 to the side wall of the ship, and make the lower part of the salvage mechanism 3 submerged below the water surface;

[0047] S2. During the ship's journey, the salvage mechanism 3 retrieves the algae from the river channel and puts it into the shell 1.

[0048] S3. The algae falling into the outer shell 1 will exert downward pressure on the tray 6. Subsequently, under the action of the drive mechanism 8, the dehydration component 5 will squeeze and dehydrate the algae at the bottom inside the outer shell 1.

[0049] S4. The dehydrated water flows back into the river through the outlet 10. The dehydrated algae will be collected in the storage tank 11, and the staff can clean it regularly.

[0050] Working principle: The device can be fixed to a boat using the mounting bracket 2. When fixing it, ensure the retrieval mechanism 3 is positioned away from the boat and its lower part is submerged in water. This allows the mechanism to effectively retrieve algae. The device is then moved along the river by the boat. The motor 52 rotates the upper roller 45. The conveyor belt 46 not only rotates the lower roller 45 but also causes multiple filter plates 48 to rotate along its path. Initially, the filter plate 48 at the bottom of the conveyor belt 46 rotates to the front, retrieval algae as it leaves the water. As the filter plate 48 crosses the highest point of the conveyor belt 46, its concave surface changes from facing upwards to downwards. The conveyor belt 46 is inclined with a lower front and a higher rear, and the feed plate 4 is also inclined with a higher front and a lower rear. Therefore, when the filter plate 48 flips, the algae scooped from the water inside it will be poured onto the feed plate 4. With the cooperation of the inclined structures of the two, the poured algae will fall into the middle of the feed plate 4 and will not leak out from the gap between the front end of the feed plate 4 and the conveyor belt 46. Moreover, the width of the feed plate 4 is much larger than that of the filter plate 48, so the algae will not fall from the sides. When the filter plate 48 moves to the gap between the feed plate 4 and the conveyor belt 46, under the pressure of the front end of the feed plate 4, the filter plate 48 will flip along the hinge position of the sleeve 49 and the central shaft 47 to adapt to the obstruction of the feed plate 4. After standing up, it will pass through the gap between the feed plate 4 and the conveyor belt 46. After passing through, the filter plate 48 will return to its original shape under the rotational force of the second coil spring 50, ready for use when scooping algae again.

[0051] The algae entering the outer casing 1 from the feed plate 4 first fall onto the two trays 6. The water in the algae leaks from the outlet holes 10 on the trays 6 into the inclined trough 9, and then flows back into the river channel from the outlet holes 10 on the bottom of the inclined trough 9. As the amount of algae increases, its weight also increases, causing the two trays 6 to gradually compress the compression spring 23 and tighten. The trays 6 then slide downwards towards the inside of the outer casing 1. During this sliding process, the gear 24 rotates due to the action of the toothed column 38. The ratchet 29 and pawl 30 inside the gear 24 do not restrict the relative rotation of the gear 24 and the rotating rod 25 during this process. However, the rotating rod 25, restricted by the ratchet 29 and pawl 30 on the side away from the trays 6, cannot rotate in the direction of the gear 24's rotation at this time, thus preventing... When gear 24 rotates, friction causes the rotating rod 25 to rotate as well. The rotation of gear 24 during its descent causes the first coil spring 28 to tighten and store force. While the rotational force generated by the first coil spring 28 tends to cause gear 24 to rotate, the hinged toothed column 38 is blocked by the stop block 39 and cannot rotate upwards. When gear 24 is completely out of the area where the multiple toothed columns 38 are located, gear 24 will rotate under the rotational force of the first coil spring 28. Because the multiple pawls 30 corresponding to gear 24 are hinged to the inner wall of gear 24, the rotation of gear 24 will cause the pawls 30 to rotate. Since the rotation direction of the pawls 30 at this time is opposite to the direction of the teeth on the ratchet 29, gear 24 will pass through... The pawl 30 drives the rotating rod 25 to rotate together. The outer ratchet 29 is sleeved on the outer wall of the rotating rod 25, so the outer ratchet 29 is not affected by the outer pawl 30 and can rotate. During the rotation of the rotating rod 25, it will press the bidirectional threaded groove 34 through the guide block 33 in the first circular groove 32. Since the slide rod 26 is slidably connected to the lifting seat 20 and cannot rotate, the pressing of the guide block 33 on the bidirectional threaded groove 34 will cause the slide rod 26 to make linear reciprocating motion. Initially, the guide block 33 will cause the slide rod 26 to translate inward. At this time, the pressing block 37 on the slide rod 26 will cause the pallet 6 to rotate along the rotating shaft 7 by pressing the guide groove 36. Because the drive mechanism 8 is centrally symmetrically arranged, the two pallets The two trays 6 move towards the center and clamp the algae. The first coil spring 28 rotates at an extremely high speed at the beginning stage. At the same time, the span of the middle turn of the bidirectional threaded groove 34 is larger than the span of each of the other turns. This allows the two trays 6 to squeeze the algae at an extremely fast rotation speed. This is to prevent the algae from leaking out between the trays 6 and the inner wall of the outer shell 1. It is also to prevent the algae from being squeezed out of the gap between the two trays 6 by the huge squeezing force applied instantaneously. This ensures that the dehydration component 5 achieves the dehydration effect on the algae in the first time. Subsequently, under the action of the smaller thread at the outer end of the bidirectional threaded groove 34, the two trays 6 will consolidate the dehydration of the algae at a smaller angle, further reducing the water content in the algae.

[0052] After the slide bar 26 moves to its innermost position, the rotating rod 25 is still rotating. At this time, under the continued pressure of the guide block 33 on the bidirectional threaded groove 34, the slide bar 26 will begin to move back. During the movement, the pressing block 37 on the slide bar 26 will first cause the included angle of the two support plates 6 to open at a small angle, thus opening up some space for the algae to slide down along the gap between the two plates, preventing the algae at the top from falling below the support plate 6 due to the opening being too fast. Then, the two support plates 6 will quickly open back to their original state, and the squeezed algae will spread flat on the support plate 6. Then, the guide block 33 will press on one turn of the inner end of the bidirectional threaded groove 34, causing the slide bar 26 to move outward a certain distance (the lifting seat 20 is equipped with a supply for the slide bar 26 to move towards the inner end). (The space for external sliding), at this time the outer end of the tray 6 will deflect downward, and its end will exert downward pressure on the inner end of the baffle 18. The baffle 18 will then descend along the plate groove 16. During this process, because the rotation of the first coil spring 28 is nearing its end, the downward deflection of the outer end of the tray 6 will not occur too quickly. The squeezed algae will have enough time to slide from the through opening 12 into the storage tank 11. The bottom surface of the storage tank 11 is also set as a sloping structure with a lower back and a higher front, and higher sides and a lower middle. The staff only needs to periodically clean out the squeezed algae from the movable door 19 (the up and down movement of the tray 6 is restricted by the sliding fit between the sliding shaft 13 and the shaft groove 14, and its rotation is restricted and guided by the arc groove 15).

[0053] On the other hand, when the lifting seat 20 moves to its lowest position, the pressing groove 44 on the bottom surface of the lifting seat 20 will exert a pressing force on the lower side plate 41, causing it to drive the vertical rod 40 and multiple stops 39 to move away from the lifting seat 20. In this way, the stops 39 no longer restrict the gear column 38. After the tray 6 inputs the dried algae into the storage tank 11, the gear 24 enters the final rotation stage under the action of the first coil spring 28. When the tray 6 returns to its initial angle, because there is no weight of algae on the tray 6, the compression spring 23 can lift the two trays 6 again. At this time, the gear column 38, which is no longer restricted by the stops 39, can rotate upward. The gear 24 can rise smoothly upward without being blocked by the gear column 38. When the lifting seat 20 returns to its original position, it will press the upper side plate 41 through the pressing groove 44 on the top surface, causing the vertical rod 40 and the stops 39 to return to their original positions and limit the gear column 38 for the next operation.
