[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Embodiment 1

[0042] like Figure 1-Figure 7 As shown, this embodiment provides a salvage device 100, including a supporting platform 1, a traction element 2, a salvage element 3 and a loading element 4. The supporting platform 1 can float and be fixed on the water surface of different salvage areas, so as to facilitate the salvage of grass residues or sediments in salvage areas at different positions, and the position of the salvage device 100 is fixed during the salvage process, thereby improving the stability during the salvage process. The loading element 4 is installed at one end of the supporting platform 1, and the traction element 2 is fixed on the supporting platform 1. The traction element 2 is fixedly connected to the salvage element 3 and can be disassembled, so as to facilitate the maintenance and replacement of the salvage element 3. And the rearrangement of the salvage element 3, the salvage element 3 is used to salvage grass residues or sediments in the water body, and the traction element 2 can drive the salvage element 3 to move to the loading element 4, and the salvage element 3 drives the grass residues or sediments in the water body to move to the loading element 4. When unloading is required, the grass residues or sediments on the loading element 4 can be unloaded. The salvage element 3 is directly driven to move by the traction element 2, avoiding manual dragging of the salvage element 3, saving labor, and the machine pulling method can provide greater traction force than manual pulling, thereby accelerating the salvage speed and improving the salvage efficiency.

[0043] Specifically, the supporting platform 1 includes a fixed platform 11 and two floating platforms 12. The floating platform 12 is a pontoon. The buoyancy of the floating platform 12 is utilized. When the supporting platform 1 needs to be moved, the supporting platform 1 is driven by a ship to move on the water surface so as to salvage different salvage areas. The movement is convenient. After arriving at the designated salvage area, the fixed platform 11 is directly anchored or otherwise fixed at a designated position, thereby facilitating the salvage operation. An installation platform 13 is fixed on each side of the fixed platform 11. One end of the installation platform 13 away from the fixed platform 11 is fixedly connected to each floating platform 12. By supporting both sides of the fixed platform 11, the support stability is improved. The salvage element 3 can be recovered between the two floating platforms 12. The loading element 4 is installed on one side of the fixed platform 11, that is, the loading element 4 is located on a side wall where the floating platform 12 is not installed.

[0044] The fishing element 3 is a fishing net, such as Figure 8-10 As shown, the salvage net includes a blocking net 31, a supporting net 32, a floating body 33 and a weight 34. The blocking net 31 and the supporting net 32 ​​are overlapped and fixedly connected to form the main body of the salvage net, and the supporting net 32 ​​is used to support the blocking net 31, thereby improving the overall strength. The supporting net 32 ​​and the blocking net 31 can be deformed for easy recovery. The aperture of the supporting net 32 ​​is larger than that of the blocking net 31. The floating body 33 is fixed on a long side of the main body, and the two ends of the floating body 33 extend to the two short sides of the main body respectively. The two ends of the floating body 33 are respectively fixedly connected to a traction rope. The weight 34 4 is fixed on the other long side of the body, and the two ends of the weight 34 extend to the two short sides of the body respectively. The float 33 is used to float on the water surface, and the weight 34 is used to fall into the water body, so that the salvage net is in an unfolded state, which is convenient for salvage and avoids the situation that the salvage net can only be completely laid on the water surface during the salvage process and cannot be salvaged. Preferably, the size of the salvage net is designed according to the water depth of the salvage area, and the salvage net can be driven to recover and salvage grass residues or sediments by pulling the two ends of the traction rope. Preferably, the weight 34 can be an iron chain, a sinker, etc.

[0045] The traction element 2 includes two first winches 21 and two fixed pulleys 22. The two first winches 21 are fixed on different floating platforms 12 respectively. The first winches 21 are fixed on the floating platform 12 through the mounting base 14, and the first winches 21 are located on the side of the floating platform 12 away from the loading element 4. When the first winches 21 rotate, the salvage net can be driven to be recovered, and the recovery length of the salvage net can be extended, which is convenient for cleaning grass residues or sediments. The brackets of the two fixed pulleys 22 are fixed on the two mounting platforms 13 respectively, and the steel wire of the first winches 21 is fixed on the two mounting platforms 13. The ropes are passed around different fixed pulleys 22 respectively, and the fixed pulleys 22 provide stable support for the wire ropes. Preferably, the wire ropes of the two first winches 21 are cross-arranged, so that when the two first winches 21 are working, the two ends of the salvage net can move toward the loading element 4 and also move toward each other, so that the salvage net can drive grass residues or sediments into the top of the loading element 4. The traction ropes at both ends of the salvage net are fixedly connected to the wire ropes on different first winches 21 and can be disassembled, and the salvage net can be recovered under the drive of the two first winches 21.

[0046] The fixed platform 11 is a rectangular platform, and the fixed platform 11 has two fixed side walls and two salvage side walls, the fixed side walls are parallel to the salvage direction of the salvage element 3, and the salvage side walls are perpendicular to the salvage direction of the salvage element 3;

[0047] A mounting platform 13 is fixed on each of the two fixed side walls. The loading element 4 is hinged on one of the salvage side walls to ensure the normal rotation of the loading element 4, so as to facilitate the outflow of water on the loading element 4 by changing the angle between the loading element 4 and the horizontal plane. An unloading element 5 is hinged on the other salvage side wall. The unloading element 5 can rotate. The unloading element 5 and the loading element 4 are arranged relative to each other, that is, during the salvage process, the salvage net first reaches the upper end of the loading element 4, and then the loading element 4 is tilted to drain the water in the grass residue or sediment, and then the salvage net is continued to be dragged to drive the grass residue or sediment to move until it moves to the unloading element 5. By tilting the unloading element 5 in the direction away from the loading element 4, the lower end of the unloading element 5 is close to the transport ship and located at the upper end of the transport ship, so that the grass residue or sediment in the salvage net can be pushed into the transport ship with the help of manpower, so as to realize the centralized treatment of the grass residue or sediment after salvage.

[0048] The loading element 4 includes a loading plate 41 and two baffles 43. One end of the loading plate 41 in the length direction is hinged on the fixed platform 11. One end of the two baffles 43 is fixed on the two long sides of the loading plate 41 respectively. The other end of the baffle 43 extends upward in a direction perpendicular to the loading plate 41. The salvaging element 3 can be recovered to the area between the two baffles 43. The two baffles 43 are used to block the two ends of the loading plate 41 so that the salvage net can be recovered through the upper end of the loading plate 41 to prevent the salvage net from extending outside the baffle 43 and affecting the rotation of the loading plate 41.

[0049] The loading element 4 also includes an extension plate 42 and two limit plates 44. The extension plate 42 is an isosceles trapezoidal plate, and the upper bottom of the extension plate 42 is fixed to one end of the loading plate 41 away from the unloading element 5, and the upper bottom length of the extension plate 42 is equal to the length of the side wall of the loading plate 41 for installing the extension plate 42. The two limit plates 44 are respectively fixed on the two waists of the extension plate 42 and extend vertically upward from the extension plate 42, that is, one end of the loading element 4 has a large opening and the other end has a small opening. During the recovery process, the end with a large opening on the loading element 4 first contacts the salvage net, and then can guide the salvage net to facilitate recovery.

[0050] A second winch 6 and a hanger 7 are respectively fixed on each mounting platform 13. The second winch 6 is fixed on the mounting platform 13 through a mounting base 14. The steel wire ropes of the two second winches 6 pass through the upper ends of the hangers 7 respectively and are fixedly connected to the two limit plates 44. The hanger 7 is used to support the steel wire rope of the second winch 6. The second winch 6 can drive the loading element 4 to fold around the fixed platform 11 toward the direction close to the unloading element 5. The steel wire rope is supported and changed in direction by the hanger 7, so that the second winch 6 can drive the extension plate 42 and the loading plate 41 to fold, thereby reducing the pulling force required for folding and improving efficiency.

[0051] The unloading element 5 includes a mounting frame, an unloading plate 51 and a lifting element 52. The upper end surface of the unloading plate 51 is higher than the upper end surface of the fixed platform 11, so that the unloading plate 51 can be rotated to the downward end to be located above the transport ship, thereby realizing the collection and cleaning of grass residues or sediments. The mounting frame is fixed on the mounting platform 13, and the lifting element 52 is fixed on the mounting frame. The action end of the lifting element 52 is hinged to the end of the unloading plate 51 away from the fixed platform 11. One end of the unloading plate 51 is hinged to the fixed platform 11 through a hinge shaft, and the lifting element 52 can drive the unloading plate 51 to rotate around the hinge shaft. Preferably, the lifting element 52 is a hydraulic cylinder.

[0052] Embodiment 2

[0053] like Figure 7-10As shown, this embodiment provides a salvage method, using the salvage device 100 in the first embodiment, the area to be cleaned is divided into relatively independent areas by gridding and numbered, and then the zoned salvage and cleaning is performed according to the implementation plan, including the following steps:

[0054] S1: Assemble the salvage device 100, transport it to the corresponding salvage area by ship and fix it, use a motor boat to arrange the salvage net, pull the traction ropes at both ends of the salvage net, and connect them to the two first winches 21 respectively;

[0055] S2: Start the two first winches 21 to recover both ends of the salvage net at the same time, and tighten the salvage net to move it in the direction close to the loading element 4. During the recovery process, the salvage net salvages and collects the grass residue or sediment in the area. Preferably, before the salvage net moves to contact the loading plate 41, the end of the loading plate 41 away from the unloading plate 51 is controlled to flip downward to facilitate the movement of the salvage net to the loading plate 41. When the salvage net drives the grass residue or sediment to move to the upper end of the loading plate 41, the loading plate 41 is controlled to tilt by the second winch 6, and the water in the grass residue or sediment is drained into the water body along the loading plate 41, so as to achieve preliminary dehydration of the grass residue or sediment for collection and treatment;

[0056] S3: When unloading grass residue or sediment, the first winch 21 continues to drive the salvage net to move, and the salvage net drives the grass residue or sediment to move to the upper end surface of the unloading element 5, and a transport ship is moved to the end of the unloading element 5 away from the loading element 4. Under the action of the lifting element 52, the unloading plate 51 is driven to rotate and tilt, and the end surface of the unloading element 5 used for carrying grass residue or sediment is away from the loading element 4, so that the grass residue or sediment on the unloading plate 51 can be sent to the transport ship through manual processing, so as to realize the unloading and collection of grass residue or sediment;

[0057] If the same salvage area needs to be salvaged multiple times, the salvage net is rearranged after the last salvage is completed, the wire rope of the first winch 21 is released, and the salvage net is moved in the direction opposite to the recovery direction, one end of the salvage net is removed and connected to a motor boat, and the movement of the motor boat drives one end of the salvage net to move, and the salvage net is unfolded, so that the two ends of the salvage net are respectively connected to the wire ropes of the two first winches 21, and the above steps are repeated to achieve the next salvage.

[0058] The present specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
