Description

Technical Field

[0002] With the development of society, rivers, as an important part of the ecosystem, have attracted much attention for their ecological environment. Various garbage, such as plastic bottles, packaging bags, branches, and abandoned fishing gear, are often piled up at the bottom of rivers. These garbage not only affect the beauty of the river, but also cause serious harm to the river ecology. Plastic garbage is difficult to degrade and will remain at the bottom of the river for a long time, continuously releasing harmful substances, polluting the water body, affecting the living environment of aquatic organisms, and may cause fish to die from accidental ingestion, destroying the water ecological balance; branches and other debris will hinder the flow of water, affect the normal hydrodynamic conditions of the river, cause local water flow to slow down, silt to accumulate, and further deteriorate the riverbed environment.

[0003] However, the existing manual cleaning method of riverbed garbage requires a lot of manpower and time. For river areas with large areas and more garbage, cleaning work is often difficult to carry out in an all-round way. In addition, the cost of manual cleaning is high, which increases the economic burden of river management. At the same time, manual cleaning operations are difficult, and workers need to operate underwater or with the help of special tools. There are certain safety risks, such as drowning and being scratched by sharp garbage. This also limits the effective implementation of cleaning work to a certain extent, making it difficult to solve the riverbed garbage problem in a timely and thorough manner, and the river's ecological environment continues to deteriorate.

[0034] The driving mechanism 6 also includes a fixed frame 604 and an air bag 605. The fixed frame 604 has multiple symmetrically distributed on both sides of the outer wall of the planting box 1. The fixed frame 604 provides an installation base for the air bag 605. The air bag 605 has two fixedly installed inside the fixed frame 604 on both sides. The air bag 605 can provide buoyancy to keep the device floating on the water surface.

[0035] A first filter plate 101 is fixedly installed at both the front and rear ends of the planting box 1. The first filter plate 101 can prevent the silt inside the planting box 1 from leaking and protect the aquatic plants in the planting box 1. A sieve plate 102 is fixedly installed inside the planting box 1. The sieve plate 102 is located on the top of the mounting block 501. The sieve plate 102 can prevent the aquatic plants from being discharged along with the silt.

[0036] A cleaning port 201 is provided at the bottom of the filter box 2, and the cleaning port 201 is located between the sealing cover 301 and the crushing wheel 401. The cleaning port 201 is convenient for cleaning the debris in the filter box 2. Two symmetrically distributed sealing doors are movably installed inside the cleaning port 201.

A second filter plate 202 is fixedly installed inside the filter box 2, and the second filter plate 202 is located between the sealing cover 301 and the cleaning port 201. The second filter plate 202 can filter out garbage fragments to prevent them from entering the planting box 1.

[0037] Working principle: Before use, first place silt suitable for aquatic plants inside the planting box 1, and then plant aquatic plants with the ability to purify harmful substances above the screen plate 102. When working, the buoyancy of the airbag 605 can be adjusted by inflating it, so that the device can float stably on the river surface. When it is necessary to move the device to a designated location to clean up riverbed garbage, start the two fourth drive motors 602, and the fourth drive motors 602 drive the drive paddles 603 to rotate. By changing the rotation speed of the two drive paddles 603, the device can be moved and turned on the water surface, so that it can flexibly reach the riverbed garbage cleaning areas at different locations in the river.

[0038] When the river bottom garbage needs to be cleaned, the second drive motor 315 is started, and the second drive motor 315 drives the take-up wheel 312 to rotate, and the take-up wheel 312 releases the pull rope 313. At this time, the counterweight block 314 loses the pulling force of the pull rope 313, and falls downward under its own gravity, and drives the suction head 310 to move downward synchronously, and at the same time stretches the steel wire telescopic tube 309 until the suction head 310 reaches the river bottom.

[0039] Then, the first drive motor 303 is turned on, and the first drive motor 303 drives the first drive shaft 302 and the paddle 304 to rotate at high speed. The paddle 304 rotates rapidly in the sealing cover 301, so that a negative pressure environment is formed inside the sealing cover 301. Under the action of the negative pressure, the suction head 310 generates suction to suck the silt and garbage on the riverbed into the suction head 310, and then transports them to the inside of the filter box 2 through the steel wire telescopic tube 309, and moves in the direction of the feed pipe 305.

[0040] While the first drive shaft 302 rotates, the gear grooves 403 at both ends of its outer wall and the outer wall of the top crushing wheel 401 support shaft transmit power to the two crushing wheels 401 through the cooperation of the driving belt 404 and the driving gear 402, driving the two crushing wheels 401 to rotate in opposite directions at the same time. When the garbage enters the filter box 2, it is broken into smaller pieces under the crushing action of the two crushing wheels 401, and the crushed garbage and sludge continue to move toward the feed pipe 305. During this process, the second filter plate 202 can block the garbage fragments to prevent them from entering the subsequent links, while the sludge and river water can smoothly pass through the second filter plate 202. The sludge and river water that pass through the second filter plate 202 enter the interior of the sealing cover 301 through the feed pipe 305, and then pass through the first discharge pipe 306, the second discharge pipe 307 and the discharge block 308 in turn, and finally are discharged into the interior of the planting box 1 from both sides of the top of the planting box 1.

[0041] With the long-term use of the device, a certain amount of silt will accumulate inside the planting box 1. When some of the silt needs to be removed, the third drive motor 508 is started. The third drive motor 508 drives the third drive shaft 506 to rotate, and through the meshing transmission of the first bevel gear 505 and the second bevel gear 507, it drives multiple second drive shafts 503 to rotate at the same time, thereby starting the auger 504 to start working. During the rotation of the auger 504, the silt at the bottom of the planting box 1 is transported out from the mud outlet block 502.

[0042] When the silt at the bottom of the planting box 1 is cleared, the silt on the top will naturally fall under the action of gravity and pass through the sieve plate 102 to reach the bottom of the planting box 1. Due to the presence of the sieve plate 102, the aquatic plants can be effectively prevented from falling with the silt, thereby ensuring the normal growth of the aquatic plants in the planting box 1.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
