Description

Technical Field

[0001] The invention relates to the technical field of marine antifouling, and mainly relates to a disposable antifouling mechanism for a small underwater docking station. Background Art

[0002] Underwater docking stations are common in the marine industry, and are mainly used for information exchange with underwater unmanned vehicles and energy replenishment. To achieve the above functions, the unmanned vehicle needs to enter the internal channel of the docking station through sound and light guidance, and the docking station will plug, unplug, lock and fix it. However, in the marine environment, the docking channel of the exposed aircraft is often contaminated by marine organisms, resulting in docking failure. Especially for some special-purpose disposable docking stations, the information value is huge, and docking failure will cause huge cost losses. For this reason, a reliable protection technology is needed for the anti-fouling of the docking station channel, at least to ensure effective protection of marine organisms before the first docking. And on small underwater docking stations, there is often not enough space and electrical interfaces to deploy an additional channel covering mechanism. Generally, only anti-fouling paint is used, and the effect is poor. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a disposable anti-fouling mechanism suitable for a small underwater docking station.

[0004] The purpose of the present invention is achieved through the following technical solutions. A disposable anti-fouling mechanism suitable for a small underwater docking station, comprising a channel guide port and a channel cover plate, wherein the channel guide port is arranged at the channel port of the docking station, and the channel cover plate shields the channel port in the form of a cover plate; the channel cover plate comprises an anti-rotation structure, a hinge structure and an adapter, and a hinge structure is arranged at the bottom of the channel cover plate, and a hinge point that can be rotatably detached is formed between the hinge structure and the channel guide port; the latch connected to the docking station locks the channel cover plate through the adapter, and the adapter is also fixed with a compression spring; in the locked state, the compression spring is compressed, and once the latch is unlocked, the upper part of the channel cover plate is instantly subjected to a turning force under the action of the compression spring, and rotates around the bottom hinge point and falls off the docking station.

[0005] As a preferred technical solution, there are two rectangular anti-rotation structures on the inner side of the channel cover plate, which are used to limit the left and right shaking of the channel cover plate.

[0006] As a preferred technical solution, the hinged structure is a protruding hemispherical structure, which is in hinged contact with a hemispherical pit on the channel guide port of the docking station.

[0007] As a preferred technical solution, the latch is fixedly connected to the plug-in and pull-out motion module of the docking station, and the locking and releasing of the latch is achieved by means of the plug-in and pull-out motion, without adding an additional power source.

[0008] As a preferred technical solution, the channel cover is made of engineering plastics, which has a density greater than seawater. It is manufactured in large quantities at low cost using an injection molding method and is no longer recycled after being dropped.

[0009] As a preferred technical solution, the outer side of the channel cover is coated with antifouling paint to suppress the impact of marine organisms on the docking station.

[0010] As a preferred technical solution, the compression spring is made of rust-proof stainless steel.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0019] like Figure 1 , Figure 4As shown, the present invention provides a disposable anti-fouling mechanism suitable for a small underwater docking station, including a channel guide port 7 and a channel cover plate 3. The channel guide port 7 is arranged at the channel port of the docking station, and the channel guide port 7 is in a trumpet shape. The channel cover plate 3 shields the channel port in the form of a cover plate.

[0020] like Figure 2 , Figure 3 As shown, the channel cover plate 3 includes an anti-rotation structure 4, an articulated structure 5 and an adapter 2. The channel cover plate 3 is made of engineering plastics with a density greater than that of seawater. It is manufactured in large quantities at low cost using an injection molding method. It is no longer recycled after falling. The outer side of the channel cover plate 3 is coated with an anti-fouling paint to inhibit the impact of marine organisms on the docking station. The bottom of the channel cover plate 3 is provided with an articulated structure 5. The specific structure of the articulated structure 5 is a protruding hemispherical structure, which is in hinged contact with the hemispherical pit on the channel guide port 7 of the docking station. The channel guide port provides an upward support force, and a hinge point that can be rotatably detached is formed between the protruding hemispherical structure and the hemispherical pit. The anti-rotation structure 4 is specifically a rectangular structure with two places on the inner side of the channel cover plate 3, which is used to limit the left and right shaking of the channel cover plate 3, and when fixed in the channel, the mechanism is limited to rotate in the horizontal plane. The anti-rotation structure 4 is inserted into the inner side of the channel, and is limited with the plane on the front side of the channel. The size is a clearance fit to avoid jamming when falling off.

[0021] The latch 6 is fixedly connected to the plug-in and pull-out motion module of the docking station, and the locking and unlocking of the latch are achieved by means of the plug-in and pull-out motion, without the need to add an additional power source. The latch 6 connected to the docking station locks the channel cover 3 through the adapter 2. The adapter 2 is also fixedly connected with a compression spring 1. The compression spring 1 is made of stainless steel rust-proof material to avoid rapid corrosion. The compression spring 1 is fixed in the mounting hole of the adapter 2 by an interference fit. A latch hole is also reserved on the adapter. The latch 6 is inserted into the latch hole on the adapter 2, and the channel cover 3 is completely locked. In the locked state, the compression spring 1 is compressed. Once the latch 6 is unlocked, the upper part of the channel cover 3 is instantly subjected to a flipping force under the action of the compression spring 1, and it rotates around the bottom hinge point and falls off the docking station.

[0022] The working principle of the present invention is described below:

[0023] Before docking begins, the docking station uses the anti-fouling mechanism proposed by the present invention to physically protect the passage. Figure 4 As shown, the docking station plug-in module moves to avoid the position in the channel, and the latch 6 of the anti-fouling mechanism moves accordingly (no additional power source is required) to release the lock. Under the thrust applied by the compression spring 1, the channel cover 3 quickly rotates around the hinge point on the channel guide opening 7 and falls to the seabed, and the docking channel opening is no longer covered.

[0024] 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 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 based on the protection scope of the claims.
