[0016] A further technical solution of the present invention is: in the water drainage mesh plate, the 2 vertical distance s between 1 and

[0017] The technical solution of the present invention is as follows: A method for salvaging floating garbage on the water surface, which is applied to a floating garbage salvage ship on the water surface. The method is as follows:

[0018] S01. Before salvaging the floating garbage, place the floating garbage salvage ship on the water surface, and drive the electric push rod to shorten, so that the rotating plates A, B, and C all rotate upward above the hull, so that both the rotating plates B and C are above the water surface, and the rotating plate C is in a state of protruding upward, thus making preparations for the floating garbage salvage ship to move on the water surface;

[0019] In this step, since the rotating plates B and C are above the water surface, on the one hand, the moving resistance is reduced, which is convenient for the floating garbage salvage ship to move on the water surface. On the other hand, when the salvage operation is not carried out, the garbage on the water surface is prevented from entering the water drainage grid plate uncontrollably;

[0020] S02. First, start two motors A, and the two motors A respectively drive the corresponding propellers A to operate, so that the floating garbage salvage ship moves to the target water area where the garbage is to be cleaned; then drive the electric push rod to extend, so that the rotating plates A, B, and C all rotate downward below the hull, so as to immerse the rotating plates B and C in the water, and the rotating plate C is in a horizontal state; then the two steering gears act synchronously, driving the water drainage grid plate to rotate downward, so that the water drainage grid plate fits the rotating plate B, thus making preparations for the floating garbage salvage ship to receive floating garbage;

[0021] In this step, the two propellers A operate at different speeds, and the differential steering of the floating garbage salvage ship can be realized;

[0022] S03. First, start the motor B, and the motor B drives the propeller B to operate, so that the water in the target water area continuously flows through the water flow channel, thereby forming a vortex, driving the floating garbage on the water surface to enter the water drainage grid plate through the rotating plate C; when a certain amount of floating garbage is collected, the motor B stops running, and the two steering gears act synchronously, driving the water drainage grid plate to rotate upward. During the upward rotation of the water drainage grid plate, it rotates by itself under its own weight and the weight of the garbage. When the water drainage grid plate rotates above the open mouth of the hull, the garbage on the water drainage grid plate slides into the garbage storage bin, that is, the floating garbage salvage ship realizes the salvage of floating garbage on the water surface;

[0023] In this step, repeat the process of creating a vortex - collecting garbage - transferring garbage several times to fill the garbage storage bin to the maximum load capacity;

[0024] S04. First, drive the electric push rod to shorten, so that the rotating plates A, B, and C all rotate upward above the hull, so that both the rotating plates B and C are above the water surface, and the rotating plate C is in a state of protruding upward; then drive the floating garbage salvage ship to move to the shore, and the staff takes out the garbage storage bin to dump the garbage.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. It can be remotely controlled to move to the target waters and automatically collect the floating garbage in the target waters. After collecting the garbage, it can be remotely controlled to return to the shore. Compared with the traditional method of manually boarding a ship to salvage floating garbage on the water surface, on the one hand, it greatly reduces the workload of manual salvage, on the other hand, it avoids the safety hazards of manual salvage of floating garbage on the water surface. On the other hand, since it does not need to be manned, the size can be designed to be relatively small, and it can easily enter narrow waters to carry out garbage salvage operations.

[0027] 2. The control method is simple and reliable:

[0028] 2.1. The position and posture of the drain screen can be controlled only by the steering gear. When the drain screen rotates to the lower end of its motion stroke, the drain screen can fit the upper surface of the rotating plate B and cover the water inlet of the rotating plate B. At this time, the upper part of the drain screen can receive garbage, and water enters the water inlet of the rotating plate B through the holes on the drain screen. When the drain screen rotates to the upper end of its motion stroke, the drain screen is eccentrically l 2 If the drain mesh is installed as a reference, the drain mesh will automatically deflect under its own weight and the weight of the garbage it carries, so that the long side of the drain mesh that is relatively close to the hull rotates downward, and the long side of the drain mesh that is relatively far from the hull rotates upward. Through the above-mentioned automatic deflection, the garbage carried by the drain mesh can be poured into the inner cavity of the hull.

[0029] 2.2. The position and posture of the rotating plate assembly can be controlled only by the electric push rod. The rotating plates A, B, and C are linked by the cleverly designed connecting rod assembly, thereby realizing the three-way linkage of the rotating plates A, B, and C. The linkage effect is as follows: the extension of the electric push rod drives the rotating plates A, B, and C to rotate downward. On the one hand, the rotating plate B can be submerged in the water, which is convenient for the drain mesh plate to rotate downward and also submerge in the water. On the other hand, the rotating plate C can be flattened, which is convenient for floating garbage to pass through the rotating plate C and enter the upper part of the drain mesh plate; the shortening of the electric push rod drives the rotating plates A, B, and C to rotate upward. On the one hand, the rotating plate B can be above the water surface, which is convenient for the salvage ship in an empty or fully loaded state to move on the water surface. On the other hand, the rotating plate C can be in a nearly vertical state, which is convenient for the salvage ship to be in a state with a fence structure when it does not need to salvage garbage.

[0030] 3. Based on the setting of the vortex creating device, a vortex can be formed around the garbage collection bin. The water flow in the vortex enters the inner cavity of the garbage collection bin from the garbage inlet of the garbage collection bin, and is then discharged from the water permeable holes at the bottom of the garbage collection bin, thereby helping to converge the flow at the garbage inlet of the garbage collection bin on the water surface and improving the efficiency of garbage collection.

[0031] 4. l in the drain screen 2The vertical distance s from l 1 and the rotational resistance F of the water drainage net plate along the two hinge points. These two parameters are related to the flipping speed of the water drainage net plate. The larger s is, the faster the flipping speed is; the larger F is, the slower the flipping speed is. When the value of s is 6%-9% of the short side length of the water drainage net plate and the value of F is 45%-55% of the self-weight of the water drainage net plate, the water drainage net plate can complete the flipping (from the horizontal 0° to the downward 70°) within 3-4 s, thus ensuring that the water drainage net plate stably and continuously transfers the garbage into the inner cavity of the ship. If the water drainage net plate flips too fast, the garbage will slide off the water drainage net plate before the water drainage net plate rotates upward above the ship and cannot accurately fall into the inner cavity of the ship. If the water drainage net plate flips too slowly, the garbage transfer time will be too long, thus reducing the efficiency of garbage salvage.

[0063] The present invention is used for salvaging floating garbage on the water surface, and the working process is as follows:

[0064] 1. Before salvaging the floating garbage, place the floating garbage salvage ship on the water surface, drive the electric push rod 48 to shorten, so that the rotating plates A41, B42, and C43 all rotate upward above the hull 1, so that the rotating plates B42 and C43 are both above the water surface, and moreover, the rotating plate C43 is in a state of protruding upward, thus making preparations for the floating garbage salvage ship to move on the water surface.

[0065] In this step, since the rotating plates B42 and C43 are above the water surface, on the one hand, the moving resistance is reduced, facilitating the movement of the floating garbage salvage ship on the water surface, and on the other hand, it avoids the uncontrolled entry of garbage on the water surface onto the water drainage grid plate 31 when the salvage operation is not carried out.

[0066] 2. First, start two motors A, and the two motors A respectively drive the corresponding propellers A23 to operate, so that the floating garbage salvage ship moves to the target water area to be cleaned of garbage; then drive the electric push rod 48 to extend, so that the rotating plates A41, B42, and C43 all rotate downward below the hull, so as to immerse the rotating plates B42 and C43 in the water, and moreover, the rotating plate C43 is in a horizontal state; then the two steering gears 32 act synchronously, driving the water drainage grid plate 31 to rotate downward, so that the water drainage grid plate 31 fits the rotating plate B42, thus making preparations for the floating garbage salvage ship to receive floating garbage.

[0067] In this step, the two propellers A23 operate at different speeds, and the differential steering of the floating garbage salvage ship can be realized.

[0068] 3. First, start the motor B, and the motor B drives the propeller B54 to operate, so that the water in the target water area continuously flows through the water flow channel 300, thereby forming a vortex, driving the floating garbage on the water surface to enter the water drainage grid plate 31 through the rotating plate C43; when a certain amount of floating garbage is collected, the motor B stops running, and the two steering gears 32 act synchronously, driving the water drainage grid plate 31 to rotate upward. During the upward rotation of the water drainage grid plate 31, it rotates by itself under its own weight and the weight of the garbage. When the water drainage grid plate 31 rotates above the open mouth of the hull 1, the garbage on the water drainage grid plate 31 slides into the garbage storage bin 200, that is, the floating garbage salvage ship realizes the salvage of floating garbage on the water surface.

[0069] In this step, repeat the process of creating a vortex - collecting garbage - transferring garbage several times until the garbage storage bin is filled to the maximum load capacity.

[0070] 4. First, drive the electric push rod 48 to shorten, so that the rotary plates A41, B42, and C43 all rotate upward towards the hull, so that both the rotary plates B42 and C43 are above the water surface, and moreover, the rotary plate C43 is in a state of protruding upward; then drive the surface floating garbage salvage ship to move to the shore, and let the staff take out the garbage storage bin 200 and dump the garbage in it.

The outer sleeve has a cylindrical structure with open ends at both ends. Inside its inner hole, a detachable filter A, a grid-type mounting platform, and a detachable filter B are sequentially arranged from one end to the other end. An installation area A for arranging Motor B and Propeller B is provided between the detachable filter A and the grid-type mounting platform. Motor B is fixedly installed inside the sealed housing, and the shaft of Motor B passes through the top wall of the sealed housing. A dynamic seal is achieved between the shaft of Motor B and the top wall of the sealed housing through a sealing ring. Propeller B is connected to the shaft of Motor B and is located outside the sealed housing. The upper end of the outer sleeve is fixedly connected to the lower end of Rotating Plate B and encloses the water inlet hole on Rotating Plate B, thereby forming a water flow channel between the water inlet hole on Rotating Plate B, the upper port of the outer sleeve, the inner hole of the outer sleeve, and the lower port of the outer sleeve. The garbage containment bin is a container with an open upper end, is adapted to the shape of the inner cavity of the ship, and is detachably installed in the inner cavity of the ship. The method is as follows: S01, Before salvaging floating garbage, place the surface floating garbage salvage ship on the water surface, drive the electric push rod to shorten, so that Rotating Plate A, Rotating Plate B, and Rotating Plate C all rotate upward above the hull, so that both Rotating Plate B and Rotating Plate C are above the water surface, and Rotating Plate C is in an upward-extended state, thus making preparations for the surface floating garbage salvage ship to move on the water surface. In this step, since Rotating Plate B and Rotating Plate C are above the water surface, on the one hand, the moving resistance is reduced, facilitating the movement of the surface floating garbage salvage ship on the water surface, and on the other hand, it avoids the uncontrolled entry of garbage on the water surface onto the draining mesh plate when no salvage operation is carried out. S02, First start the two Motors A, and the two Motors A respectively drive the corresponding Propellers A to operate, so that the surface floating garbage salvage ship moves to the target water area to be cleaned of garbage; then drive the electric push rod to extend, so that Rotating Plate A, Rotating Plate B, and Rotating Plate C all rotate downward below the hull, so as to immerse Rotating Plate B and Rotating Plate C in the water, and Rotating Plate C is in a horizontal state; then the two steering gears act synchronously, driving the draining mesh plate to rotate downward, so that the draining mesh plate fits Rotating Plate B, thus making preparations for the surface floating garbage salvage ship to receive floating garbage. In this step, the two Propellers A operate at different speeds, and the differential steering of the surface floating garbage salvage ship can be achieved. S03, First start Motor B, and Motor B drives Propeller B to operate, so that the water in the target water area continuously flows through the water flow channel, thereby forming an eddy current, driving the floating garbage on the water surface to enter the draining mesh plate through Rotating Plate C; when a certain amount of floating garbage is collected, Motor B stops running, and the two steering gears act synchronously, driving the draining mesh plate to rotate upward. During the upward rotation of the draining mesh plate, it rotates by itself under its own weight and the weight of the garbage. When the draining mesh plate rotates above the open end of the hull, the garbage on the draining mesh plate slides into the garbage containment bin, that is, the surface floating garbage salvage ship salvages the floating garbage on the water surface. In this step, repeat the process of generating eddy current - collecting garbage - transferring garbage several times until the garbage containment bin is filled to its maximum load capacity. S04. First, drive the electric push rod to shorten, so that the rotating plates A, B, and C all rotate upward above the hull, so that both the rotating plates B and C are above the water surface, and the rotating plate C is in a state of protruding upward; then drive the surface floating garbage salvage ship to move to the shore, and the staff takes out the garbage storage bin to dump the garbage.
