Technical Field

[0002] When there are a lot of debris such as leaves and branches in the river channel, it will affect the ecological environment of the river channel and may cause other water conservancy equipment in the river channel to be affected by the debris such as leaves and branches. Therefore, ecological restoration sewage treatment equipment will be used to salvage the debris such as leaves and branches floating in the river channel.

The above-mentioned prior art provides a garbage collection component to replace the manual salvage method to clean up river garbage, with high collection efficiency and low cost, and the push plate can flatten the garbage in the rectangular shell to prevent all the river garbage from being piled up in the area within the rectangular shell.

[0004] However, when collecting some longer branches and other debris, these debris will occupy more collection space after salvage, and the river ecological restoration sewage treatment equipment is often floating in the river or fixed in the river. After salvaging longer branches and other debris, it also needs to be transported to the recycling and processing site to process the longer branches and other debris. This results in longer branches and other debris occupying more transportation space when transporting, and the transportation efficiency is reduced. Summary of the invention

[0030] Compared with the prior art, the above technical solutions of the present invention have the following beneficial technical effects:

[0031] The driving device drives the fishing net and plate 1 to salvage the sundries in the river channel into the collection part, and drives the turntable to rotate during the salvage process, thereby driving the piston rod 1 to lift and lower in the inner cavity of the piston cylinder 1, so as to pump the external air into the piston cylinder 1 along the air inlet part, and then squeeze it out from the air outlet part into the inner cavity of the piston cylinder 2, further driving the piston rod 2 in the inner cavity of the piston cylinder 2 to move towards the direction of the cylinder 3. When the air in the inner cavity of the piston cylinder 2 is full, it enters the cylinder 2 along the pipe 1 and the L-shaped pipe, thereby driving the piston rod 3 to descend in the inner cavity of the cylinder 2, and through the resistance of the spring 2 and the resistance ring, the piston rod 3 descends slowly, so as to ensure that the piston rod 3 will not descend past the pipe 2 until the air in the inner cavity of the piston cylinder 2 is full.

[0032] After that, the air enters the inner cavity of the cylinder 3 along the pipe 2. The air entering the inner cavity of the cylinder 3 pushes the piston rod 4. At this time, the elastic force of the spring 3 drives the piston rod 4 to compress the air. As the air increases, the piston rod 4 crosses the connection part of the pipe 3 and the cylinder 3. Subsequently, the air enters the pipe 5 through the pipe 3, and then is blown out to the surface of the fishing net through the blowing head on the pipe 5, so as to blow off the lighter sundries such as leaves stained with water on the surface of the fishing net into the collection part, avoiding their adhesion to the outer surface of the fishing net.

[0033] When some longer sundries enter the inner cavity of the collection part, they will squeeze the trigger part to move towards the housing. First, the round rod will move along the horizontal groove 1. After that, when the horizontal groove 1 is located at the vertical groove, the elastic force of the spring 4 drives the round rod on the blocking part 2 to rise into the horizontal groove 2. At this time, the sundries have fallen on the surface of the conveying unit. The blocking part 2 rises, so that the air in the inner cavity of the cylinder 3 is squeezed by the piston rod 4 and enters the position of the piston cylinder 2 close to the cylinder 3 along the pipe 4, and the blocking part 1 rises, and the air on the side of the inner cavity of the piston cylinder 2 close to the collection part is discharged. Then, the high-pressure gas squeezed by the piston rod 4 and the elastic force of the spring 1 drive the chopping part to chop the longer sundries on the conveying unit, thus realizing the treatment of the longer sundries and avoiding the situation that their large volume affects the transportation efficiency.

[0054] The piston assembly includes a second piston cylinder 15, a first spring 16, and a second piston shaft 17;

The air outlet portion 13 communicates with one end of the second piston cylinder 15 close to the collection portion 14.

[0078] Example 3, as Figures 1 - 5 shown, a sewage treatment device for river ecological restoration proposed by the present invention. Compared with Example 2, the air blowing mechanism in this embodiment includes a third pipe 31, a fifth pipe 47, and an air blowing head 48;

[0079] The pipe three 31 is connected to the cylinder three 28. The pipe five 47 is connected to the pipe three 31 and is located inside the fishing mechanism. The air blowing head 48 is connected to the pipe five 47.

[0080] The pipe five 47 is located inside the fishing net 5, and the air blowing head 48 faces upward above the collection part 14.

[0081] Both the first elastic member 33 and the second elastic member 40 are composed of a telescopic rod and a fifth spring.

[0082] In summary, in the present invention, the frame 1 is installed in the river channel, and the collection part 14 is located above the water surface, or the frame 1 is installed on the hull, and the hull drives the frame 1 to move in the river channel for fishing debris on the river channel.

[0083] The lowermost part of the frame 1 is in the water. Then, the driving device 2 is started to drive the sprocket 3 to rotate. The rotation of the sprocket 3 drives the chain 4 to operate, and the operation of the chain 4 drives the fishing net 5 to operate, so as to convey the floating debris in the water to the inner cavity of the collection part 14. Then, the smaller debris falls between the triggering parts 35 onto the conveying unit 49 and is conveyed into the storage space.

[0084] When the sprocket 3 rotates, it drives the turntable 7 to rotate. The limiting post 8 on the turntable 7 drives the bottom end of the sleeve rod 9, the piston shaft one 10, to move along the axis direction of the piston cylinder one 11. When the piston shaft one 10 rises in the inner cavity of the piston cylinder one 11, the external air is drawn into the inner cavity of the piston cylinder one 11 through the air intake part 12. When the piston shaft one 10 descends in the inner cavity of the piston cylinder one 11, the air in the inner cavity of the piston cylinder one 11 is conveyed from the air outlet part 13 to the side of the inner cavity of all the piston cylinders two 15 close to the collection part 14, thereby pushing the piston shaft two 17 to move towards the direction of the cylinder three 28, making the first spring 16 stretched.

[0085] When there is more air in the inner cavity of the piston cylinder two 15, the high-pressure air enters the inner cavity of the cylinder two 23 along the pipe one 19 and the L-shaped pipe 22, thereby driving the piston shaft three 25 to descend. At this time, due to the elasticity of the second spring 24 and the resistance of the resistance ring 26 to the piston shaft three 25, only high-pressure gas can push it open. When the piston shaft three 25 descends past the pipe two 27, the air enters the inner cavity of the cylinder three 28 along the pipe two 27. At this time, the elasticity of the third spring 29 drives the piston shaft four 30 to compress the air entering the inner cavity of the cylinder three 28. When the piston shaft four 30 passes the connection between the pipe three 31 and the cylinder three 28, the air will enter the pipe five 47 along the pipe three 31, and then be blown out through the air blowing head 48 to the fishing net 5, thereby blowing the debris such as leaves contaminated on the fishing net 5 into the inner cavity of the collection part 14, thus preventing these debris from contaminating the surface of the fishing net 5.

[0086] When some longer sundries enter the collection part 14, thus pushing the trigger part 35 to move towards the inner cavity of the housing 32. At this time, the round rod 46 moves relatively along the first horizontal groove 36. When it is at the vertical groove 37, the elastic force of the fourth spring 44 drives the round rod 46 into the second horizontal groove 38.

[0087] Subsequently, the longer sundries fall on the conveying unit 49. At the same time, the second blocking part 45 moves upward, making the fourth pipe 42 unblocked. The elastic force of the third spring 29 drives the piston shaft four 30 to convey the air in the inner cavity of the third cylinder 28 along the fourth pipe 42 to the side of the inner cavity of the second piston cylinder 15 close to the third cylinder 28. At the same time, the first blocking part 21 rises, so that the air on the side of the inner cavity of the second piston cylinder 15 close to the collection part 14 is discharged from the exhaust hole of the first cylinder 20.

[0088] Subsequently, the high-pressure air entering the inner cavity of the second piston cylinder 15 combines with the elastic force of the first spring 16 to drive the chopping part 18 to split the longer sundries into several segments.

[0089] The trigger part 35 is driven by the elastic force of the first elastic part 33 to reset. The round rod 46 moves from the second horizontal groove 38 to the inclined groove 39, and after squeezing the blocking part 41 into the second elastic part 40, it returns to the first horizontal groove 36, so that the round rod 46 descends, and then drives the second blocking part 45 and the first blocking part 21 to descend. The air on the side of the second piston cylinder 15 close to the third cylinder 28 is slowly discharged, and then the air entering the inner cavity of the second piston cylinder 15 on the side close to the collection part 14 drives the piston shaft two 17 to reset, and then drives the chopping part 18 to reset.

[0090] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to this. Within the scope of knowledge possessed by those skilled in the art to which it pertains, various changes can be made without departing from the gist of the present invention.
