[0027] See also Figure 1 The shallow water area buoyancy salvage method provided by the present invention comprises the following steps:

[0028] S1, determining the relevant information of the object to be salvaged.

[0029] It is understandable that the above steps may further include:

[0030] Determine the location, size and weight of the object to be salvaged.

[0031] 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 it can also include fixed points on the object to be salvaged, and the fixed points can be two symmetrical positions of the object to be salvaged.

[0032] S2, fixing the floating salvage net 3 on the object to be salvaged and inflating it.

[0033] See also Figure 3 It is understandable that the above steps may further include:

[0034] S201, using an underwater robot or a submersible to carry a floating salvage net 3 and dive to an area near the location of the object to be salvaged.

[0035] It is known that the underwater robot or submersible dives according to the acquired position of the object to be salvaged, and may dive to a position above the object to be salvaged. The floating salvage net 3 may be formed by splicing a circular air pipe 302 and a plurality of straight pipes 301.

[0036] S202, the underwater robot or submersible connects the floating salvage net to the object to be salvaged.

[0037] It can be understood that the number of the floating salvage nets 3 can be two, which are symmetrically arranged on both sides of the object to be salvaged.

[0038] S203, inflating the floating salvage net by an underwater robot or a submersible.

[0039] It can be known that after the inflation is completed, the floating salvage net 3 can be in an umbrella shape.

[0040] S3, connecting the object to be salvaged to the salvage vessel 1 via the salvage rope 4.

[0041] It can be understood that there are two salvage vessels 1, which are respectively located on both sides of the object to be salvaged. This approach can limit the area where the object to be salvaged floats up, so that its floating state can be controlled.

[0042] S4, the unhooked float component 2 sinks to the bottom of the water along the salvage rope 4, the float 201 of the unhooked float component 2 will fall off, and the float 201 floats to the inside of the floating salvage net 3 until the buoyancy is greater than the weight of the object to be salvaged.

[0043] It can be known that when the unhooked float component 2 sinks to the bottom of the water along the salvage rope 4, the float 201 will be separated from the unhooked float component 2 under the action of gravity. The separated float 201 will float to the inside of the floating salvage net 3 until the number of floats 201 meets the preset requirements.

[0044] See also Figure 2In some embodiments, the unhooking float component 2 includes a float 201, a connecting rope, a first weight ball 204, a second weight ball 206, a connecting rod 210, a rotating rod 203, a spring 208, a cutter head 202, a guide ring 207 and a guide rope. The float 201 is connected to the connecting rod 210 through a connecting rope. A through hole is provided on the first weight ball 204. The connecting rod 210 passes through the through hole and is connected to the second weight ball 206. The rotating rod 203 is rotatably connected to the connecting rod 210, and a portion of the rotating rod 203 is located in the through hole. The cutter head 202 is connected to one end of the rotating rod 203, and the other end of the rotating rod 203 is connected to the connecting rod 210 through a spring 208, so that the cutter head 202 is away from the connecting rope in the initial state. The second weight ball 206 is connected to the guide rope through the guide ring 207, and the guide rope is slidably sleeved on the salvage rope 4.

[0045] It can be understood that under the action of the gravity of the first heavy ball 204 and the second heavy ball 206, the float 201 overcomes the buoyancy of the water and sinks. The through hole on the first heavy ball 204 allows the rotating rod 203 to rotate around the rotating shaft on the connecting rod 210 to a certain extent. When the second heavy ball 206 contacts the bottom of the water, the first heavy ball 204 will continue to move toward the bottom of the water due to the action of inertia. In this case, the first heavy ball 204 will change the initial state of the rotating rod 203, so that the rotating rod 203 overcomes the elastic force of the spring 208. The rotating rod 203 can be rotatably connected to the connecting rod 210 through the rotating shaft 209, so that the cutter head 202 approaches and contacts the connecting rope. When the cutter head 202 contacts the connecting rope, the connecting rope will be cut. After cutting, the float 201 will float to the inside of the floating salvage net 3, thereby realizing the release of the float 201 at a preset position. The structure is simple and the operation is convenient.

[0046] From the above description, it can be known that the shallow water area buoyancy salvage method provided by the present invention does not rely on large-scale equipment, has a short underwater operation time, only needs to complete the fixing work and the inflation work of the floating salvage net 3, and the remaining work is completed on the water surface, which reduces safety hazards, and evenly increases the buoyancy received by the salvaged items, reducing damage to the salvaged items.

[0047] 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. Therefore, the protection scope of the present invention shall be subject to the attached claims.
