[0028] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the description of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] In the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0030] The directions or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “front”, “back”, “top”, “bottom”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0031] The terms "first", "second", "third", etc. are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.
[0032] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.
[0033] See also Figure 1 The deep water buoyancy salvage method provided by the present invention comprises the following steps:
[0034] S1, determine the relevant parameters of the object to be salvaged.
[0035] It is understandable that the above steps may further include:
[0036] Determine the location, size, weight, fixing point of the object to be salvaged and the number of floating salvage nets 1 required.
[0037] It can be known that the position of the object to be salvaged can be the coordinate position of the object to be salvaged underwater, which can be obtained through underwater sonar, the size can also be obtained through underwater sonar, the weight can be known data provided by the person who lost the object to be salvaged, and the fixed point can be the center of gravity of the object to be salvaged. For objects to be salvaged with uniform density and regular shape, the fixed point can be the center point of the object to be salvaged.
[0038] S2, bringing the floating salvage net 1 to a location close to the object to be salvaged, and fixing the floating salvage net 1 and the object to be salvaged.
[0039] It is understandable that the above steps may further include:
[0040] S201, determining the number of floating salvage nets 1 and the number of required buoys according to the size and weight of the object to be salvaged.
[0041] It is understandable that the size also affects the number of floating salvage nets. The reason is that the weight determines the number of floating salvage nets 1. The number of buoys 2 that each floating salvage net can accommodate is certain, and the buoyancy of each buoy 2 is certain. Therefore, the number of floating salvage nets 1 required can be calculated based on the weight.
[0042] S202, the underwater robot 3 carries the floating salvage net 1 to approach the object to be salvaged.
[0043] It is understandable that when the underwater robot 3 transports the floating salvage net 1 , the floating salvage net 1 may be in an unfolded state, thereby reducing resistance during carrying.
[0044] S203, fixing the floating salvage net 1 and the object to be salvaged according to the determined fixed points.
[0045] It is understandable that the fixing method may be to connect and fix the floating salvage net 1 through a professional salvage rope.
[0046] S3, prop up the floating salvage net 1.
[0047] It is understandable that the above steps may further include:
[0048] S301, using the underwater robot 3 to pull the corners of the floating salvage net 1;
[0049] S302, and using the underwater robot 3 to prop up the floating salvage net 1 near the middle area to form an umbrella shape.
[0050] It is understandable that the underwater robot 3 can grab the four corners of the floating salvage net 1 and extend it. The area near the middle can be one or more underwater robots 3 that prop up the floating salvage net 1 to form an umbrella shape, which is convenient for the subsequent placement of the float 2.
[0051] S4, after the floating salvage net 1 is propped up, a plurality of buoys 2 are transported into the floating salvage net 1 one by one until the buoyancy is greater than the weight of the object to be salvaged.
[0052] It is understandable that the above steps may further include:
[0053] S401, transporting the floating balls one by one into the floating salvage net 1 by the underwater robot 3;
[0054] S402, evenly increase the floating balls 2 to make the buoyancy between the floating salvage nets 1 uniform.
[0055] It can be known that the buoy 2 can be transported gradually. Under the action of buoyancy, the buoy 2 fits tightly under the floating salvage net 1. The floating salvage net 1 cooperates with the buoy 2 to make the buoyancy greater than the weight of the object to be salvaged, so that the object to be salvaged floats up.
[0056] S5, the salvage object is towed to the shore by the tugboat 4 or hoisted into the ship by a crane to complete the salvage work.
[0057] It is understandable that the objects to be salvaged can be salvaged by using a tugboat 4 or a crane according to actual needs.
[0058] From the above description, it can be known that the deep-water buoyancy salvage method provided by the present invention uses a buoyancy salvage method, which is a gradual process. By gradually increasing the buoyancy, the salvaged object slowly leaves the bottom of the water. During the entire operation, the salvaged object can rise steadily, is highly safe, and is not prone to the risk of falling.
[0059] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
