Description

Technical Field

[0001] The invention belongs to the technical field of underwater equipment, and in particular relates to an anchoring compartment section. Background Art

[0002] When the underwater vehicle sails to the designated standby position, it needs to release the mooring device to change from the navigation state to the stationary state; when the vehicle receives the navigation command again, it needs to separate the mooring device and change from the stationary state to the navigation state. In order to improve the target detection capability of the vehicle in the standby state, the vehicle is usually required to maintain a stable and good stationary posture, and the mooring compartment is required to have the ability to autonomously adjust the attitude; in addition, in order to meet the high-speed navigation requirements when the vehicle enters the navigation state again, it is necessary to have a higher self-preservation ability to reduce navigation resistance and navigation noise. At present, the traditional anchoring compartment of the vehicle does not have the ability to autonomously adjust the attitude; when the vehicle enters the navigation state again, the anchoring device is thrown away as a whole, which destroys its original good hydrodynamic shape and cannot meet the requirements of low resistance and low noise during high-speed navigation. Summary of the invention

[0006] The watertight compartment is equipped with a control system and a transmission device to control the opening of the hatch, the retraction and release of the anchor rope, and the triggering of the first explosive bolt, the second explosive bolt, and the third explosive bolt.

[0007] The working project is:

[0008] 1. When the vehicle reaches the designated position, the control system receives the vehicle's command, drives the door to rotate, and opens the door.

[0009] 2. When the hatch is opened, the control system triggers the third explosive bolt to cause the anchor to fall off.

[0010] 3. The control system controls the rolling release of a certain length of anchor rope to enable the navigation body to stay.

[0011] 4. The control system regularly receives the attitude information of the underwater vehicle, and controls and adjusts the length of the anchor rope according to the attitude information to keep the underwater vehicle's resident attitude stable.

[0012] 5. After receiving the restart command, the control system triggers the first explosive bolt and the second explosive bolt, and throws away the anchor rope coil, so that the anchor rope and the anchor are separated from the underwater navigation body.

[0013] 6. The control system controls the rotation of the hatch door and closes the hatch door to achieve self-preservation of the anchoring compartment of the underwater vehicle.

[0014] On the basis of the above scheme, further, the shell is divided into a watertight compartment and a permeable compartment by a longitudinal watertight bulkhead; the shell is provided with a transverse transparent hole, which runs through the watertight compartment and the permeable compartment to serve as a channel for the overall cable line of the underwater vehicle.

[0015] On the basis of the above scheme, further, the hinged rod fixing bolt connects the hatch to the shell through the hatch hinged rod; a hatch drive motor and a hatch transmission device are provided in the watertight compartment, the hatch drive motor is connected to the control system through a cable, the hatch transmission device is connected to the second watertight gear installed on the watertight bulkhead, and the second watertight gear is engaged with the keyway on the hatch; the control system controls the operation of the hatch drive motor, and drives the hatch to rotate through the hatch transmission device and the second watertight gear to achieve opening or closing.

[0016] On the basis of the above scheme, further, an anchor rope driving motor and an anchor rope transmission device are arranged in the watertight compartment, the anchor rope driving motor is connected to the control system through a cable, the anchor rope transmission device is connected to the first watertight gear installed on the watertight bulkhead, and the first watertight gear is engaged with the keyway on the anchor rope coil; the control system controls the operation of the anchor rope driving motor, and drives the anchor rope coil to rotate through the anchor rope transmission device and the first watertight gear, so as to realize the retraction and release of the anchor rope.

[0017] On the basis of the above scheme, further, the control system is connected to the first explosive bolt, the second explosive bolt and the third explosive bolt through a watertight connector; the watertight connector, the first watertight gear and the second watertight gear are installed on the watertight bulkhead in a through-type manner.
