Manual salvage is very accurate, but requires a lot of manpower and material resources.

[0003] Through retrieval, CN201821095414.7, an automatic ocean garbage recycling system, uses a water pump to make the garbage can move up and down to generate negative pressure to suck in water surface garbage. The above technical solutions can all achieve unmanned operation, and the water surface garbage is sucked into the garbage can. However, part of the water surface garbage will be stuck near the suction inlet of the recycling barrel wall and cannot be sucked into the garbage can. Moreover, when the garbage is collected to a certain extent, the garbage at the top will gather more and more, hindering the entry of new floating garbage, so that the garbage near the last garbage recycling barrel cannot be sucked in, affecting the usability.

[0030] Please refer to Figure 3 , 4The push-pull assembly 5 includes a push-pull driving half wheel 51 and a push-pull rod 52. The push-pull rod 52 is provided with a rack on both sides and a sliding groove 53 at the middle position. A sliding clamping shaft is installed in the sliding groove 53 and fixedly installed on the central shaft of the first driving gear 41. The racks on both sides of the push-pull rod 52 and the push-pull driving half wheels 51 on both sides are intermittently and alternately engaged. The push-pull driving half wheels 51 are symmetrically installed on the rotating shafts of the paddle driving wheels 42 and synchronously rotate with the paddle driving wheels 42. The first driving gear 41 drives the paddle driving wheels 42 on both sides to synchronously rotate through the motor. Since the push-pull driving half wheels 51 on both sides are installed in a staggered manner, when the left push-pull driving half wheel 51 rotates and the rack on the left side of the push-pull rod 52 is engaged, the push-pull rod 52 moves upward. When the left push-pull driving half wheel 51 rotates to the toothless part, the right push-pull driving half wheel 51 and the rack on the right side of the push-pull rod 52 are engaged, and the push-pull rod 52 moves downward, forming up-and-down reciprocating motion. The lower end of the push-pull rod 52 is provided with a piston part 54. The piston part 54 is sealingly and slidably fitted with the inner wall of the piston cavity 14.

[0031] As shown in Figures 5-7 , the push-pull assembly 5 includes a push-pull driving half wheel 51 and a push-pull rod 52. The push-pull rod 52 is provided with a rack on both sides and a sliding groove 53 at the middle position.

The push-pull driving half wheels 51 are symmetrically installed on the rotating shafts of the paddle driving wheels 42 and synchronously rotate with the paddle driving wheels 42. The first driving gear 41 drives the paddle driving wheels 42 on both sides to synchronously rotate through the motor. Since the push-pull driving half wheels 51 on both sides are installed in a staggered manner, when the left push-pull driving half wheel 51 rotates and the rack on the left side of the push-pull rod 52 is engaged, the push-pull rod 52 moves upward. When the left push-pull driving half wheel 51 rotates to the toothless part, the right push-pull driving half wheel 51 and the rack on the right side of the push-pull rod 52 are engaged, and the push-pull rod 52 moves downward, forming up-and-down reciprocating motion. The lower end of the push-pull rod 52 is provided with a piston part 54. The piston part 54 is sealingly and slidably fitted with the inner wall of the piston cavity 14.

[0032] As shown in Figure 1 , 2As shown, the inner space of the middle barrel body 2 is divided into a suction chamber 12 and a piston chamber 14, the upper end of the suction chamber 12 is communicated with the garbage suction inlet 11, and the two sides of the piston chamber 14 are provided with first one-way flow valves 21, one end of the first one-way flow valve 21 is installed on the inner wall of the piston chamber 14 through a reset shaft 24, and it is to be noted that the reset shaft is a prior art which can be realized by arranging a reset spring on the shaft, and the present application will not be described in detail. The lowermost end of the piston chamber 14 is provided with a second one-way flow valve 22, one end of the second one-way flow valve 22 is installed on the lower inner wall of the middle barrel body 2 through a reset shaft 24, and the lower inner wall of the middle barrel body 2 is provided with a limiting block 23. It is to be noted that the installation position of the first one-way flow valve 21 can be at the bottom of the two sides of the piston chamber 14 or at the middle position.

[0033] As shown in Figure 1 , 5 When the piston part 54 moves upward, the paddle 46 is lifted upward and does not contact the water surface, the second one-way flow valve 22 is closed at the limiting block 23, and the first one-way flow valve 21 is opened into the piston chamber 14, at this time, the suction chamber 12 and the piston chamber 14 are communicated, and the garbage on the water surface is sucked into the suction chamber 12 from the outside.

[0034] As shown in Figure 2 When the piston part 54 moves downward, the paddle 46 is recovered downward and back to the garbage suction inlet 11, and the garbage is pushed into the garbage suction inlet 11 by contacting the water surface, the first one-way flow valve 21 is closed, the second one-way flow valve 22 is opened, the collection chamber 13 space is communicated with the piston chamber 14, the piston part 54 continues to move downward, the garbage is transferred into the collection chamber 13, and then the piston part 54 moves upward to repeat the above process, so as to realize the garbage collection on the water surface.

[0035] In some other embodiments, the paddle 46 can be provided with a round arc rod-shaped pushing claw at the front end.

[0036] In some other embodiments, as shown in Figure 8 , the same as embodiment 1, except that the outer side of the middle barrel body 2 is provided with a floating barrel 6, the floating barrel 6 is provided with an exhaust and inflation valve, the floating barrel 6 floats the garbage collection device on the water surface, and cooperates with the garbage suction inlet 11 and the paddle 46 to complete the garbage collection action.

[0037] In some other embodiments, as shown in Figure 8As shown, a through hole is arranged at the upper end of the piston cavity 14, and a flow guide sleeve 25 is arranged at the lower surface of the upper barrel body 1 and fixed by bolts. The flow guide sleeve 25 is in the shape of a circular arc plate. When the piston part 54 moves upward, the liquid in the upper end of the piston cavity 14 is discharged from the through hole, and the discharged liquid is guided downward by the flow guide sleeve 25 and re-enters the suction cavity 12. The suction cavity 12 forms a downward flow guide, further increasing the suction force of the garbage suction port 11. When the piston part 54 moves downward, the volume of the upper end of the piston cavity 14 increases to suck the water in the suction cavity 12, and the liquid level of the suction cavity 12 decreases, so that the garbage suction port 11 sucks the garbage outside.

[0038] In some other embodiments, as shown in Figure 8 As shown, a solar cell panel 7 is arranged above the upper barrel body 1. The solar cell panel 7 is used to shield the motor from rainwater and can be used to generate electricity. The solar cell panel is electrically connected to the battery panel, the inverter, the control assembly and other power generation components. The solar power generation components are prior art and will not be described in detail. It should be noted that the power generation components can also be connected to other power generation components such as wind power generation, liquid level difference power generation, etc.

[0039] In some other embodiments, in order to make the collection device more intelligent, the upper barrel body 1 is also provided with an electric air pump. The electric air pump is connected to the floating barrel 6 through an air guide pipe. A liquid level sensor is arranged at the position of the garbage suction port 11 of the middle barrel body 2. The liquid level sensor senses the liquid level, and the electric air pump inflates or deflates the floating barrel 6, so that the garbage suction port 11 of the collection device is kept level with the water surface. It should be noted that the liquid level sensor, the electric air pump and other components for inflating and deflating the floating barrel 6 are mature technologies and will not be described in detail.

[0040] In some other embodiments, in order to make the collection device movable, the floating barrel 6 is provided with electrically controlled exhaust valves arranged upward, downward, leftward and rightward. The electrically controlled exhaust valves, the electric air pump and the controller are electrically connected. The movement of the collection device can be realized by controlling the air flow discharge thrust of the electrically controlled exhaust valves through the controller.

[0041] In some other embodiments, as shown in Figure 9 , 10 As shown, the outlet part of the lower end of the flow guide sleeve 25 extends to the first one-way flow valve 21 of the suction cavity 12. The flow guide sleeve 25 can guide the medium in the upper part of the piston part 54 to the first one-way flow valve 21. The guided medium can impact the valve port, which can effectively prevent the garbage from being stuck in the first one-way flow valve 21. Further, the flow guide sleeve 25 includes a circular arc guide section 251, a variable diameter straight section 252 and a circular arc outlet section 253. Figure 9As shown, the upper end of the circular arc guide section 251 is in a circular arc shape, for guiding the unordered water flow downward, the reducing straight section 252 further guides the downward water flow downward, the upper end of the reducing straight section 252 is large in opening and the lower end is small in opening, which can play a role of pressure boosting, the outlet diameter of the circular arc outlet section 253 is further reduced, and the circular arc angle corresponds to the valve port position, so as to improve the outlet water pressure flow rate and flush the valve port.
