Description

Technical Field

[0001] The utility model relates to the technical field of seabed bases, and particularly relates to a main box body for a seabed base. Background Technique

[0002] A seabed base is a small automatic observation platform sunk on the seabed. By using various monitoring instruments carried in the central cabin, it can conduct long-term, continuous, synchronous, fixed-point and automatic measurements on the marine environment, which is of great significance for marine disaster prevention, seaport engineering, deep-sea mining engineering, submarine pipeline engineering, etc.

[0003] A complete set of seabed base systems includes a main box body, a floating body, an instrument cabin, a rope cabin, a recovery rope, a deployment device, a detection instrument and an acoustic release unit. The main box body is an important part of the seabed base. A reasonable seabed base main box body can reduce the influence on the sea current in the seabed sitting state, and prevent the seabed base from having the phenomenon of sediment scouring under the platform or platform overturning due to the action of the sea current.

[0004] However, in the existing seabed bases, due to the relatively thick and soft silt at the bottom of the ocean, and the relatively heavy gravity of the seabed base itself, during the settlement process, the seabed base is extremely easy to sink into the deeper silt when contacting the seabed. The silt at the seabed not only buries the seabed base, but also may affect the operation of the internal structure of the seabed base, which will have a certain impact on marine detection. Content of the Utility Model

[0005] The purpose of the utility model is to provide a main box body for a seabed base to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A main box body for a seabed base, comprising a main box body, floating balls and a water storage tank. An inner cavity is opened inside the main box body. A partition board is arranged in the horizontal direction of the inner cavity. The partition board divides the inner cavity into a first inner cavity and a second inner cavity. The first inner cavity is located above the second inner cavity. Detection instruments are arranged in the first inner cavity. A gas storage tank is fixedly connected to the center of the bottom of the second inner cavity. An air injection pipe is arranged at the center of the top of the gas storage tank. The top of the air injection pipe is located above the top of the main box body. An injection valve is arranged at the top of the air injection pipe. A plurality of connecting pipes are arranged on the surface of the gas storage tank. The other ends of the connecting pipes are connected to the floating balls. A water storage tank is fixedly connected to the bottom of the outer surface of the main box body. The floating balls are located inside the water storage tank.

[0008] Preferably, a waterproof sealing ring is sleeved at the connection between the air injection pipe and the main box body.

[0009] Preferably, the rear side of the surface of the water storage tank is made of rigid material, and the other parts of the surface of the water storage tank are made of rubber material.

The top of the injection pipe 3 is located above the top of the main box body 1. An injection valve is arranged at the top of the injection pipe. The injection valve is a prior art. When injecting gas into it through the injection valve, it can be injected more conveniently. When the injection device is removed, the injection valve will be sealed with the outside to prevent the internal gas from flowing out. Here, the specific structure inside it will not be described in detail. A plurality of connecting pipes 10 are arranged on the surface of the gas storage tank 9. The other ends of the connecting pipes 10 are connected to the floating ball 4. The bottom of the outer surface of the main box body 1 is fixedly connected with a water storage tank 8. The floating ball 4 is located inside the water storage tank 8.

[0022] Furthermore, a waterproof sealing ring 2 is sleeved at the connection between the injection pipe 3 and the main box body 1. The waterproof sealing ring 2 can perform a certain degree of waterproof sealing to prevent seawater from entering the inside of the seabed base main box body 1 and affecting the detection equipment.

[0023] Furthermore, the rear side of the surface of the water storage tank 8 is made of a rigid material, and the other parts of the surface of the water storage tank 8 are made of a rubber material. An exhaust port 12 is arranged on one side of the surface of the floating ball 4. The surface of the exhaust port 12 is connected to a certain place on the other parts of the surface of the water storage tank 8. The other end of the exhaust port 12 is located outside the outer surface of the water storage tank 8.

[0024] The surface of the exhaust port 12 is provided with an exhaust valve. After the exhaust valve is opened, it will cause the internal gas to flow out quickly.

When the seabed foundation is settled, seawater will enter the water storage tank 8 from the side water injection ports 5 and the upper and lower water injection ports 6. When the seabed foundation contacts the seabed ground, the seabed foundation does not directly contact the seabed ground. The water storage tank 8 directly contacts the seabed, preventing the silt on the seabed ground from entering the seabed foundation and protecting the seabed foundation. When it is necessary to retract the seabed foundation, all the gas valves 11 are opened, and the gas in the gas storage tank is input into the floating ball 4 through the connecting pipe. After the floating ball 4 is filled with gas, it will expand and eject the water inside the water storage tank from the water storage tank 8. At this time, the inside of the floating ball will be filled with gas, providing a large buoyancy for the seabed foundation and making the seabed foundation float more quickly and facilitating recovery.
