[0025] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0026] Example: As attached Figure 1 , 2 , 3, 4, 5, 6, 7 and attached Figure 8 As shown, a device for removing floating objects on the water surface comprises a motor unit 1 which floats on the water surface and provides rotational power, and a rotating plate unit 2 which is connected to the motor unit 1 and is used for collecting floating objects on the water surface.

[0027] In this embodiment, the motor unit 1 is used to provide rotational power to the rotating plate unit 2, and the motor unit 1 has the function of floating on the water surface.

[0028] The motor unit 1 includes a floating board 101 floating on the water surface, a motor bracket 102 arranged on the floating board 101, a motor 103 fixed on the motor bracket 102, a rotating column part 104 arranged on the motor 103 for driving the rotating board unit 2 to rotate, a rotating column hole 105 arranged on the floating board 101 for inserting the rotating column part 104, and a rope 106 arranged on the floating board 101 to fix it on the water surface.

[0029] In this embodiment, the floating board 101 floats on the water surface, the motor bracket 102 supports the motor 103, the motor 103 has waterproof protection measures, and the switch, rotation speed and rotation direction can be controlled by remote control. The rope 106 is used to fix the floating board 101 to the shore to prevent the device from drifting away with the water flow. At the same time, when recovering the device, the staff can complete the recovery operation by pulling the rope 106 on the shore.

[0030] The rotating column portion 104 includes a rotating column 104a arranged on the motor 103 for driving the rotating plate unit 2 to rotate, a support ring 104b arranged on the rotating column 104a and located below the rotating plate unit 2, a horizontal fixing block 104c arranged on the rotating column 104a, and a vertical fixing column 104d arranged on the horizontal fixing block 104c for driving the rotating plate unit 2 to rotate.

[0031] In this embodiment, the support ring 104b is engaged with the rotating plate unit 2, and the rotating plate unit 2 is lifted to allow it to rotate freely, and the vertical fixing column 104d is engaged with the rotating plate unit 2 to drive it to rotate.

[0032] The rotating plate unit 2 includes a rotating plate 201 connected to the support ring 104b, a net bag 202 arranged on the rotating plate 201 for collecting floating objects on the water surface, a rotating plate hole 203 arranged on the rotating plate 201 for inserting the rotating column 104a, an elastic hook 204 arranged on the rotating plate 201 and engaged with the vertical fixed column 104d to enable the rotating plate 201 to rotate unidirectionally, and an annular groove 205 arranged at the bottom of the rotating plate 201 for engaging the top edge of the support ring 104b.

[0033] In this embodiment, the net bag 202 is set on the water surface, with one part above the water surface and the other part below the water surface. The support ring 104b can rotate smoothly in the annular groove 205 while preventing the rotating column 104a from shaking in the rotating plate hole 203.

[0034] The elastic hook portion 204 includes an elastic hook fixing block 204a arranged on the inner side wall of the rotating plate hole 203, an elastic hook fixing column 204b connected to the elastic hook fixing block 204a, an elastic hook 204c connected to the elastic hook fixing column 204b, and an elastic hook hole 204d arranged on the elastic hook 204c for passing through the elastic hook fixing column 204b.

[0035] In this embodiment, the elastic hook 204c can rotate around the elastic hook fixing column 204b, and can only rotate to a certain angle. The elastic hook 204c is L-shaped. When the vertical fixing column 104d rotates toward the inside of the L-shaped opening, the vertical fixing column 104d can drive the elastic hook 204c to rotate, thereby driving the entire rotating plate 201 to rotate. When the vertical fixing column 104d rotates toward the outside of the L-shaped opening, the elastic hook 204c will automatically retract when contacting the vertical fixing column 104d, so that the vertical fixing column 104d cannot drive the elastic hook 204c to rotate.

[0036] The elastic hook portion 204 further includes a fixing column support ring 204e disposed on the elastic hook fixing column 204b, and a fixing block annular groove 204f disposed on the lower surface of the elastic hook fixing block 204a for engaging with the top edge of the fixing column support ring 204e.

[0037] In this embodiment, the fixing column support ring 204e can rotate smoothly in the fixing block annular groove 204f.

[0038] The elastic hook portion 204 further includes a spring baffle 204g disposed on the elastic hook fixing column 204b, a spring 204h disposed on the spring baffle 204g, and an elastic hook baffle 204i disposed on the inner wall of the elastic hook hole 204d and connected to the spring 204h.

[0039] In this embodiment, when the vertical fixing column 104d rotates toward the outside of the L-shaped opening and the elastic hook 204c contacts the vertical fixing column 104d, the elastic hook baffle 204i presses the spring 204h, causing it to shrink under the joint action of the spring baffle 204g, so that the elastic hook 204c will automatically retract when contacting the vertical fixing column 104d. When the elastic hook 204c is separated from the vertical fixing column 104d, the spring 204h lifts up the elastic hook baffle 204i under the action of the spring baffle 204g, and the elastic hook 204c automatically returns to its original position.

[0040] The elastic hook portion 204 also includes a fan-shaped groove 204j arranged on the elastic hook fixing column 204b, an arc-shaped opening 204k arranged on the upper surface of the elastic hook fixing column 204b and connected to the fan-shaped groove 204j, a movable baffle 204t arranged on the fan-shaped groove 204j, a rotating column 204m arranged in the fan-shaped groove 204j and connected to the movable baffle 204t, a rotating column groove 204n arranged on the upper inner side surface and the lower inner side surface of the fan-shaped groove 204j for engaging the rotating column 204m, an active column 204u passing through the arc-shaped opening 204k and connected to the movable baffle 204t, an elastic hook opening groove 204p arranged on the lower inner side surface of the fan-shaped groove 204j and engaging the active column 204u, and an elastic hook closing groove 204q arranged on the lower inner side surface of the fan-shaped groove 204j and engaging the active column 204u.

[0041] In this embodiment, the movable baffle 204t can manually keep the elastic hook 204c close to the inner wall of the rotating plate hole 203. At this time, the vertical fixed column 104d will not contact the elastic hook 204c when rotating. It is generally used when the rotating plate is not used for a long time. When adjusting, the movable column 204u is lifted, pulled out from the elastic hook opening slot 204p, and moved along the arc mouth 204k to the elastic hook closing slot 204q. At this time, the movable baffle 204t drives the elastic hook baffle 204i to compress the spring 204h, thereby driving the elastic hook 204c to rotate. When the movable column 204u moves to the top of the elastic hook closing slot 204q, the movable column 204u is lowered and inserted into the elastic hook closing slot 204q to fix the movable baffle 204t, thereby fixing the elastic hook baffle 204i.

[0042] In addition, if the elastic hook 204c is to be put into operation again, lift the movable column 204u, pull it out from the elastic hook closing slot 204q, and move it along the arc-shaped opening 204k toward the elastic hook opening slot 204p. At this time, the movable baffle 204t drives the elastic hook baffle 204i to release the spring 204h, thereby driving the elastic hook 204c to rotate. When the movable column 204u moves to the top of the elastic hook opening slot 204p, put down the movable column 204u and insert it into the elastic hook opening slot 204p, so that the elastic hook 204c can work again.

[0043] In addition, the movable baffle 204t serves to limit the elastic hook baffle 204i, thereby limiting the elastic hook 204c to rotate only to a certain angle, so that the vertical fixing column 104d will not be separated from the elastic hook 204c.

[0044] The elastic hook portion 204 also includes an active baffle hole 204w arranged on the active baffle 204t for passing through the active column 204u, an active baffle groove 204x arranged inside the active baffle 204t, an active column plate 204r arranged in the active baffle groove 204q, and an active column spring 204s arranged on the active column plate 204r and connected to the active baffle groove 204q.

[0045] In this embodiment, the movable column spring 204s is used to push the movable column plate 204r downward, so that the movable column 204u is engaged with the elastic hook opening groove 204p or the elastic hook closing groove 204q.

[0046] The device for removing floating objects on the water surface is provided with two rotating plate units 2, wherein the radius of the rotating plate 201 included in the rotating plate unit 2 arranged at the bottom is longer than that of the rotating plate 201 included in the rotating plate unit 2 arranged at the top, the mesh of the net bag 202 included in the rotating plate unit 2 arranged at the bottom is larger than that of the net bag 202 included in the rotating plate unit 2 arranged at the top, and the openings of the elastic hooks 204 included in the two rotating plate units 2 face opposite rotation directions.

[0047] In this embodiment, as shown in the attached Figure 1 As shown, the net bag 202 arranged on the rotating plate 201 below is located on the outside of the net bag 202 arranged on the rotating plate 201 above. The purpose of this arrangement is that large floating particles can be preferentially captured by the net bag 202 with large meshes, and the small floating particles that are not captured are then captured by the net bag 202 with small meshes on the inside, avoiding the risk of mesh clogging.

[0048] The above is a detailed description of the embodiments of the present invention, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
