[0041] Please refer to Figures 1 to 9 , a preferred embodiment of the marine floating garbage collection device, the marine floating garbage collection device, it includes the hull 100, negative pressure suction mechanism 200, garbage storage warehouse 300, separation mechanism 400 and two groups of interval arrangement of the anti-pushing tail spray mechanism 500.

[0042] The hull 100 is provided with two floating bodies 110 arranged at intervals. As shown in Figure 1 The hull 100 is also provided with a roof 120 connected to the top end of the two floating bodies 110. The roof 120 can shield the separation mechanism 400, the garbage storage warehouse 300, etc.

[0043] The negative pressure suction mechanism 200 is installed on the ship body 100, and comprises a flow guide plate 210 and two negative pressure assemblies. Each negative pressure assembly comprises a negative pressure cavity 220, a propeller 230 and a suction motor 240. The flow guide plate 210 is located between the two floating bodies 110 and is provided with a plurality of suction holes 211 which can simultaneously communicate with the inside of the negative pressure cavity 220 and the outside. The two propellers 230 are respectively installed in the two negative pressure cavities 220 and are respectively connected with the two suction motors 240. The suction motor 240 drives the propeller 230 to rotate, so that negative pressure is generated in the negative pressure cavity 220. Under the action of the negative pressure, seawater and garbage enter the flow guide plate 210, and the seawater can be discharged after entering the negative pressure cavity 220 from the suction hole 211.

[0044] Specifically, as shown in Figure 4 and Figure 5 , the suction motor 240 and the propeller 230 are connected through a transmission belt 250 and a transmission rod 260. The transmission rod 260 transversely passes through the negative pressure cavity 220 and is connected with the propeller 230. The transmission rod 260 and the negative pressure cavity 220 need to be sealed to ensure that negative pressure is generated in the negative pressure cavity 220.

[0045] As shown in Figure 2 and Figure 4 , the left and right sides of the front end of the flow guide plate 210 are provided with circular connecting blocks 212. The inner sides of the two floating bodies 110 are provided with upward and downward extending sliding grooves 111, and a sliding block (not shown) is further provided. The sliding block can be fixed with the corresponding connecting block 212 and is in sliding cooperation with the sliding groove 111. Therefore, the front end of the flow guide plate 210 can be floated up and down according to the water depth. In addition, the density of the flow guide plate 210 is slightly greater than that of seawater, and the floating effect is better. In the embodiment, the inside of the negative pressure cavity 220 is connected with the outside in addition to the suction hole 211. Therefore, when the flow guide plate 210 is floated upward, seawater can also enter the negative pressure cavity 220 from below the flow guide plate 210, so as to reduce the water flow resistance and increase the water inflow to improve the power performance.

[0046] The garbage storage bin 300 is installed on the ship body 100 and is located behind the flow guide plate 210.

[0047] The separation mechanism 400 is installed between the flow guide plate 210 and the garbage storage bin 300, and can transport the garbage entering the flow guide plate 210 into the garbage storage bin 300.

[0048] In the embodiment, the separating mechanism 400 comprises a separating motor 410, a separating rotor 420, separating claws 430 and a filter seat 440. The separating motor 410 is installed on the ship body 100. The filter seat 440 is connected between the flow guide plate 210 and the garbage storage bin 300. The separating rotor 420 is drivingly connected with the separating motor 410. The separating claws 430 are drivingly connected with the separating rotor 420. Garbage flows from the flow guide plate 210 to the separating claws 430 and is driven by the rotation of the separating claws 430 to enter the garbage storage bin 300.

[0049] In the embodiment, the separating rotor 420 comprises two rotor end portions 421 and three separating connecting rods 422. The cross section of the rotor end portion 421 is a Luro triangle. The three vertices between the two rotor end portions 421 are fixedly connected by the three separating connecting rods 422 respectively. The inner sides of the two floating bodies 110 of the ship body 100 are respectively provided with a square shaft hole 112. The two rotor end portions 421 respectively extend into the square shaft holes 112 so that the separating rotor 420 rotates in an eccentric center. The separating claws 430 are provided in three groups. Each group of the separating claws 430 comprises a plurality of separating claws 430 arranged at intervals. Each separating claw 430 is a hollow long strip. Each group of the separating claws 430 is movably sleeved on the outer sides of the adjacent two separating connecting rods 422. The separating rotor 420 rotates to drive the separating claws 430 to rotate and move up and down.

[0050] In the embodiment, the bottom surface of the filter seat 440 is substantially flush with the flow guide plate 210. The bottom surface of the filter seat 440 is provided with a plurality of filter grates 441 which are connected with the inside of the negative pressure cavity 220. The filter grates 441 can prevent garbage from falling into the negative pressure cavity 220 and causing the negative pressure cavity 220 to be blocked. Meanwhile, the separating claws 430 can extend into the filter grates 441 to make room during the rotation. The rear end of the filter seat 440 is further provided with an L-shaped rear seat 442. When the bottom end of the separating claws 430 abuts against the L-shaped rear seat 442 during the rotation, the top end of the group of the separating claws 430 remains to extend upward under the abutment of the L-shaped rear seat 442. When the bottom end of the separating claws 430 rotates to the filter grates 441, the separating claws 430 extend downward into the filter grates 441 under the action of the gravity of the separating claws 430 until the top end of the separating claws 430 is sleeved on one of the separating connecting rods 422. The separating claws 430 realize the process of extension and retraction through the circulation. When the separating claws 430 are in the horizontal position, garbage can move to the separating claws 430 in the horizontal position. The separating claws 430 rotate to drive the garbage to rotate. When the garbage moves close to the garbage storage bin 300, the separating claws 430 start to retract. The garbage falls into the garbage storage bin 300.

[0051] In the embodiment, the separating rotor 420 further comprises a plurality of separating plates 423 in the shape of a Luro triangle, three separating connecting rods 422 respectively penetrating through three vertices of the separating plates 423, and the separating plates 423 separating the three groups of separating claws 430.

[0054] In the embodiment, the reverse thrust port 511 is provided with a reverse thrust rotating shaft 513 connected with the rudder driving assembly, the reverse thrust plate 520 is fixed to the reverse thrust rotating shaft 513, and the rudder driving assembly comprises a rudder 530, a first rocker 531, a second rocker 532, a swing rod 533 and a pull rod 534, the two ends of the first rocker 531 are connected with the rudder 530 and one end of the second rocker 532 respectively, the other end of the second rocker 532 is connected with the top end of the swing rod 533, the lower end of the swing rod 533 is connected with the pull rod 534, the middle segment of the swing rod 533 is in rotational fit with the ship body 100, so that the upper and lower ends of the swing rod 533 can swing forward and backward, the pull rod 534 can move forward and backward under the action of the swing rod 533, and the reverse thrust rotating shaft 513 is in transmission connection with the pull rod 534.

[0055] In the embodiment, the side edge of the pull rod 534 is provided with a pull rod rack 535, the end of the reverse thrust rotating shaft 513 is provided with a reverse thrust gear 514, the reverse thrust gear 514 is in meshing fit with the pull rod rack 535, the forward and backward movement of the pull rod 534 drives the reverse thrust rotating shaft 513 to rotate in opposite directions, thereby driving the reverse thrust plate 520 to rotate in opposite directions.

[0056] In the embodiment, each of the anti-pushing tail spray seats 510 is provided with an anti-pushing opening 511 on the left and right sides, the anti-pushing shafts 513 are provided with two anti-pushing shafts respectively arranged at the two anti-pushing openings 511, the anti-pushing gears 514 are also provided with two anti-pushing gears respectively corresponding to the two anti-pushing shafts 513, and the pull rods 534 are provided with the pull rod racks 535 on the left and right sides, and the two anti-pushing gears 514 are respectively engaged with the pull rod racks 535 on the left and right sides.

[0057] In the embodiment, the anti-pushing plate 520 includes an anti-pushing straight plate 521 and an anti-pushing arc plate 522 fixedly connected with the anti-pushing straight plate 521, and the anti-pushing arc plate 522 is reversely bent at the end thereof towards the positive outlet 512.

[0058] In the embodiment, the anti-pushing tail spray seat 510 is provided with an anti-pushing limiting groove 515 on the bottom surface, and the anti-pushing straight plate 521 is provided with a limiting rod 523 at the bottom end, the limiting rod 523 extends into the anti-pushing limiting groove 515 and is movable along the anti-pushing limiting groove 515.

[0059] In the embodiment, the ship body 100 is provided with a swing rod shaft sleeve 101, and the middle section of the swing rod 533 is provided with a swing rod rotating shaft 536, which is rotationally matched with the swing rod shaft sleeve 101.

[0060] The working process of the garbage collection device is as follows:

[0061] The suction motor 240 of the negative pressure suction mechanism 200 is started to drive the propeller 230 to rotate, at this time, the negative pressure is generated in the negative pressure cavity 220, and the garbage near the drainage plate 210 is sucked into the negative pressure cavity 220 together with the seawater under the action of the negative pressure, wherein the seawater enters the negative pressure cavity 220 from the suction hole 211 and below the suction hole 211, and flows out from the positive outlet 512 or the anti-pushing opening 511 of the anti-pushing tail spray seat 510 after flowing through the propeller 230; the garbage is sucked into the drainage plate 210 and further moves inward to a group of separation claws 430 arranged horizontally, the separation claws 430 carrying the garbage are rotated towards the garbage storage bin 300 under the action of the separation rotor 420, when the group of separation claws 430 moves close to the garbage storage bin 300, the group of separation claws 300 is retracted downward, at this time, the garbage falls into the garbage storage bin 300. The group of separation claws 430 continues to rotate to the horizontal position, and the above-mentioned action is repeated.

[0062] When the seawater enters the anti-thrust tail nozzle 510, the forward, backward, hovering or steering actions of the ship body 100 can be realized by controlling the anti-thrust tail nozzle mechanism 500. When fast forward is needed, the steering engine driving assembly is controlled to drive the anti-thrust rotating shaft 513 to rotate, so that the anti-thrust plate 520 completely closes the anti-thrust port 511. At this time, the seawater in the negative pressure cavity 220 flows out from the positive outlet 512 backward, realizing fast forward. When slow forward is needed, the anti-thrust plate 520 can be controlled to open the anti-thrust port 511 partially, so that a small amount of seawater flows out from the anti-thrust port 511 forward. At this time, the water flow thrust flowing out from the positive outlet 512 is greater than that flowing out from the anti-thrust port 511, so that the ship body 100 can move forward slowly. When the ship body 100 needs to move backward, the anti-thrust plate 520 can be controlled to close the positive outlet 512. At this time, the anti-thrust port 511 is completely opened, and the seawater in the negative pressure cavity 220 flows out from the anti-thrust port 511 forward, realizing the backward action of the ship body 100. When the ship body 100 needs to hover, the positive outlet 512 and the anti-thrust port 511 can be opened simultaneously, and the water flow thrust flowing out backward is the same as that flowing out forward, so that the ship body 100 can keep in a stationary state.

[0063] The above merely describes the preferred embodiments of the present application, and therefore cannot limit the scope of the present application. Any equivalent changes and modifications made according to the scope and content of the present application should still fall within the scope of the present application.
