When the submersible vehicle is seated or sails near the seabed, the propeller of the submersible vehicle can stir up seabed sediments and silt, so that the turbid visibility of the nearby seawater is greatly reduced. However, the diffusion conditions of the turbid seawater are poor due to the approximate still water environment, and the seawater can be recovered clearly within several weeks. This causes great trouble to the observation of the surroundings by the optical equipment of the submersible, even leading to a task failure.

as shown in fig. 4, 5 and 6, the structure of the single stay bar assembly 2 is: including four connecting pieces 202 of interval distribution, the upper surface of single connecting piece 202 can the smooth surface, the lower fixed surface has cross communicating pipe 203, the upper surface of two connecting pieces 202 that the diagonal set up is upwards, the upper surface of two other connecting pieces 202 that the diagonal set up is downwards, articulated rigid hollow vaulting pole 201 on the cross communicating pipe 203 on the connecting piece 202, twelve rigid hollow vaulting poles 201 and four connecting pieces 202 are articulated to form "well" style of calligraphy structure altogether, flexible water pipe 204 has been arranged to the inside of every rigid hollow vaulting pole 201, each flexible water pipe 204 communicates each other in the inside of cross communicating pipe 203, wherein four flexible water pipe 204 stretch out in the outside of rubber water pocket 1, a flexible water pipe 204 passes through check valve 3 and is connected with high pressure water pump, three other flexible water pipe 204 are sealed with the end cap.
The connection between the rubber water bag 1 and the brace rod component 2 adopts a vulcanization process for connection.
A brace rod component 2 is arranged in the rubber water bag 1.
The rubber water bag 1 is internally provided with a plurality of brace rod components 2 which are communicated with each other.
The specific structure and function of the invention are as follows:
mainly comprises a rubber water bag 1, a brace rod component 2, a check valve 3 and other connecting fasteners such as pin shafts and bolts.
Wherein the rubber water bag 1 is connected with the stay bar component 2 through a vulcanization process, and the rubber water bag 1 can be synchronously unfolded and folded along with the unfolding and folding of the stay bar component 2.
Wherein the stay bar component 2 comprises a flexible water pipe 204, a rigid hollow stay bar 201, a connecting piece 202 and a cross-shaped communicating pipe 203,
each flexible water pipe 204 is arranged in twelve rigid hollow support rods 201, the twelve rigid hollow support rods 201 are hinged with cross-shaped communication pipes 203 on four connecting pieces 202 through pin shafts respectively, so that a support rod assembly 2 is formed, and the flexible water pipes 204 are fully distributed on the twelve rigid hollow support rods 201 and are mutually communicated at the connecting pieces 202.
Wherein the check valve 3 is connected with one of the flexible water pipes 204 by a threaded connector, and the other flexible water pipes 204 are blocked.
Wherein the flexible water pipe 204 is connected with the rubber water bag 1 in a vulcanization process mode, so that water can be injected into the rubber water bag 1.
The device for inhibiting the raised dust and the silt on the seabed can be expanded by increasing the rigid hollow support rods 201 and the connecting pieces 202 as required, so that the coverage area of the seabed is increased, and the effect of inhibiting the raised dust and the silt is increased.
In the actual use process:
initially, the support rod assembly 2 of the device for suppressing dust and sand from the sea bottom is in a retracted state and carried by the operation submersible. When the operation submersible needs to sit on the bottom, the device is arranged on the bottom of the sea.
After the device is arranged in place, the device is connected with the check valve 3 through a high-pressure water pump system carried on the submersible, water is injected into the flexible water pipe 204 through the high-pressure water pump, the flexible water pipe 204 is gradually changed into hard from the flexible body after water is injected, and the collected rigid hollow support rod 201 is unfolded through the connecting piece 202 until the device for inhibiting the dust and the silt on the seabed is completely unfolded.
After the device is completely unfolded, water is continuously injected into the flexible water pipe 204 until the rubber water bag 1 is filled with water. After the water injection is finished, the high-pressure water pump system carried by the submersible vehicle is separated from the check valve 3, the seabed dust and sediment inhibiting device is arranged, and the submersible vehicle can be directly seated on the rubber water bag 1 to prevent sediment and sediment from being stirred up.
The vulcanization process of the invention is as follows:
crosslinking of sulfur occurs during vulcanization, which refers to the attachment of one or more sulfur atoms to the polymer chain to form a bridge. As a result of the reaction, an elastomer is formed, which may be sulfur or other related substances.
With the development of the rubber industry, crosslinking can be carried out with a variety of non-sulfur crosslinking agents. The more scientific meaning of vulcanization is therefore "crosslinking" or "bridging", i.e. the process of forming a network of macromolecules by crosslinking linear macromolecules. Crosslinking of sulfur occurs during vulcanization, which refers to the attachment of one or more sulfur atoms to the polymer chain to form a bridge. The result of the reaction is an elastomer whose properties are altered in many ways, the vulcanizing agent being sulfur or other related substances. The process of converting plastic rubber into elastic rubber or hard rubber is the physical property. The meaning of "vulcanization" encompasses not only the process of actual crosslinking, but also the process by which crosslinking occurs.
The above description is intended to be illustrative and not restrictive, and the scope of the invention is defined by the appended claims, which may be modified in any manner within the scope of the invention.
