A telescopic rod 330 is rotatably connected to one side of the L-shaped rotating plate 310, and one end of the telescopic rod 330 is rotatably connected to one end of the fixed shell 220. When cleaning garbage, the height of the rotating disk 320 is parallel to the horizontal plane, so that the rotating disk 320 is arranged facing the direction of the water flow. Under the impact of the water flow, the spiral blades at the bottom of the rotating disk 320 rotate, driving the rotating disk 320 to rotate, so that the garbage around the rotating disk 320 is driven by the rotating disk 320 to drift toward the first floating platform 110. When the distance between the two sides of the shore becomes narrower, the telescopic rod 330 is started to rotate the L-shaped rotating plate 310, thereby reducing the lateral length of the L-shaped rotating plate 310 to adapt to the water surface.

[0033] In this embodiment, second fixing grooves 131 are provided on both sides of the fixing plate 130, and second motors 340 are fixed on the inner sides of both ends of the protective shell 140. The motor shaft of the second motor 340 passes through the top of the fixing plate 130, and the outer side of the motor shaft of the second motor 340 is fixedly sleeved with a first bevel gear 350. A recycling port 112 is provided in the middle of both sides of the first floating platform 110, and a rotating leaf 370 is rotatably connected between the inner side walls of the recycling port 112. A first rotating shaft is fixed in the middle of the rotating leaf 370, and a second bevel gear 360 is fixedly sleeved on the outer side of one end of the first rotating shaft of the rotating leaf 370. The second bevel gear 360 is meshed with the first bevel gear 350. When collecting garbage, When collecting, by starting the second motor 340, the rotating blade 370 is rotated under the action of the first bevel gear 350 and the second bevel gear 360. When the garbage reaches the outside of the rotating blade 370, the rotating blade 370 rotates to move the garbage to the inside of the first floating platform 110 for preliminary collection. The bottom of the two long inner side walls of the first floating platform 110 are provided with sliding grooves 113. The inner side of the sliding groove 113 is rotatably connected with a screw rod 114. The outer side of the screw rod 114 is screwed and sleeved with a slider 115. One side of the slider 115 is rotatably connected with a toggle pin 116. A second rotating shaft is provided between the toggle pin 116 and the slider 115. The outer side of the second rotating shaft is fixed with a sleeve. A torsion spring is connected, and a first fixed groove 117 is opened at the bottom of the inner wall of the first floating platform 110 corresponding to the end position of the sliding groove 113. A first motor 118 is embedded and fixed inside the first fixed groove 117. The motor shaft of the first motor 118 passes through the first fixed groove 117 and the side wall of the sliding groove 113 and is fixedly connected to the end of the screw rod 114. When the garbage inside the first floating platform 110 is salvaged and collected, the first motor 118 is started to rotate the screw rod 114, driving the slider 115 and the toggle pin 116 to move until the toggle pin 116 reaches the position of the rear end of the sliding bar 430. At this time, when the sieve plate 440 is flipped to the side of the fixed shell 220 After dumping the garbage onto the conveyor belt 230, the end of the sliding bar 430 will drive the toggle pin 116 to rotate, and then when the sliding bar 430 rotates to a certain height, the toggle pin 116 rotates, and then the sliding bar 430 rotates, so that the toggle pin 116 is stuck in the limit block at the end of the sliding bar 430, and then the first motor 118 is started, so that the slider 115 and the toggle pin 116 drive the sliding bar 430 to move, so that the sliding bar 430 drives the screen plate 440 to slide along the sliding groove 113 on the inner side of the rotating rod 420, and after moving to the bottom of the first floating platform 110, the third motor 411 is started again to rotate the sliding bar 430 and the screen plate 440, preparing for the next round of salvage.

[0034] In this embodiment, the height of the rotating disk 320 is flush with the water surface, the bottom surface height of the support column 120 is lower than the water surface, the top surface height of the fixed shell 220 is higher than the water surface, and the rotating shaft 410 is located below the water surface. By limiting the height of the rotating disk 320 and the support column 120, the garbage floating on the water surface can smoothly enter the first floating platform 110 for collection. It can limit the height of the fixed shell 220 and the rotating shaft 410, so that after the garbage enters the first floating platform 110, the sieve plate 440 can salvage the garbage to the storage bin 221 for collection.

[0035] Working principle: When in use, the second floating platform 210 and the first floating platform 110 are placed on the water surface, so that the second floating platform 210 and the first floating platform 110 are placed in the middle of the river channel, and the L-shaped rotating plate 310 and the rotating disk 320 are arranged perpendicular to the water flow direction, so that the rotating disk 320 is flush with the water surface, and then the water flows toward the rotating disk 320. Under the impact of the water flow, the spiral blades at the bottom of the second floating platform 210 will rotate, driving the rotating disk 320 to rotate, so that the garbage on the water surface is moved on the water surface toward the direction of the first floating platform 110 under the action of the rotating disk 320. Through the cooperation of multiple rotating disks 320, the garbage can continue to move to the outside of the first floating platform 110;

[0036] When the garbage moves to the outer edge of the first floating platform 110, the second motor 340 is started, and the rotating blade 370 is rotated under the drive of the first bevel gear 350 and the second bevel gear 360, so that the garbage outside the first floating platform 110 is moved to the inside of the first floating platform 110 through the recycling port 112. After a certain amount of garbage is stored in the first floating platform 110, the third motor 411 is started to rotate the rotating shaft 410, thereby driving the rotating rod 420 to rotate, and then driving the sliding bar 430 and the screen plate 440 to rotate. Under the action of the blocking plate 422, the garbage inside the first floating platform 110 will be concentrated on the side above the screen plate 440 close to the fixed plate 130. When the screen plate 440 rotates upward, the garbage will be salvaged by the screen plate 440. Through the continuous rotation of the screen plate 440, the garbage will be driven to the upper surface of the conveyor belt 230 on the other side, and then the conveyor belt 230 is started to transport the garbage to the storage bin 221 for storage.

[0037] At this time, the toggle pin 116 is placed at the end of the sliding bar 430. When the sliding bar 430 rotates, the toggle pin 116 is rotated, and then the sliding bar 430 continues to rotate for a distance, so that the toggle pin 116 is separated from the sliding bar 430 and restored to its original state, and then the sliding bar 430 is rotated back for a distance, so that the toggle pin 116 just catches the limit block at the end of the sliding bar 430, and then the first motor 118 is started to rotate the screw rod 114, driving the slider 115 to slide inside the sliding groove 113. At this time, the toggle pin 116 will pull the sliding bar 430 to move toward the fixed plate 130, and pull the 30 and the screen plate 440 back to prepare for the next salvage;

[0038] After the toggle pin 116 moves to the other end of the sliding slot 113, when the next salvage is performed, the third motor 411 is started again to rotate the sliding bar 430. At this time, the limit block at the end of the sliding bar 430 will be separated from the toggle pin 116, and the sliding bar 430 and the screen plate 440 will rotate upward together to perform salvage;

[0039] When it is necessary to clean up the garbage on the water surface on a large scale, in order to improve work efficiency, the built-in power of the second floating platform 210 can be started to make the second floating platform 210 move on the water surface, driving the entire device to move in the direction of the water flow, thereby increasing the garbage cleaning speed. When the garbage storage bin 221 is full, the device is moved back to the shore to clean up the garbage inside the storage bin 221, and a round of garbage cleaning is completed.
