Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0016] Combine Figure 1 to Figure 3 The UUV submarine mooring device of the present invention consists of four identical parts, the four parts are installed symmetrically in pairs, and each pair includes a right hydraulic drive arm 2 and a left hydraulic drive arm 5, a right anchor 4 and a left anchor The rod 5, the right trowel 3 and the left trowel 6, that is, each part is mainly composed of three mechanisms: a hydraulic drive arm, a trowel and an anchor rod; one end of each hydraulic drive arm is hinged on the UUV body 1, The other end is hinged on the middle of the corresponding anchor rod. When the hydraulic drive arm is extended, the anchor rod can be pushed outward and downward, and when the hydraulic drive arm is contracted, the anchor rod can be pulled upward and inward to retract. One end of each anchor rod It is hinged on the UUV main bo...

Abstract

The invention provides an anchoring device and method for UUV seabed residing. The anchoring device is composed of hydraulic driving arms, retractable anchor rods and sludge grabbing shovels. In the navigation process of a UUV, each anchor rod and the corresponding sludge grabbing shovel are integrally combined and retracted at the two sides of the UUV under the action of the corresponding hydraulic driving arm to keep the streamline appearance of the UUV; when the UUV needs to reside on the seabed, the hydraulic driving arms extend to stretch out the anchor rods and the sludge grabbing shovels, and under the combined action of the hydraulic driving arms and the gravity, the sludge grabbing shovels are embedded into sludge so that the UUV stably resides on the surface of the seabed; when the UUV needs to set sail from the seabed, the hydraulic driving arms retract to drive the anchor rods and pull the sludge grabbing shovels out of the sludge, the anchor rods and the sludge grabbing shovels are retracted gradually to achieve sail setting of the UUV from the seabed. By means of the anchoring device, when resides on the seabed, the risks that the UUV shifts due to the ocean current action or buried by the sludge are avoided.

Description

Technical field [0001] The invention relates to a mooring device and method for UUV seabed staying. Background technique [0002] When UUV performs underwater reconnaissance, submarine ambushes, and acts as an underwater communication node, it needs to be stably stationed on the seabed to achieve high concealment and low energy consumption latent operations. In order to make the UUV energy-saving and easy to maneuver while sailing, the UUV is usually designed to have buoyancy equal to gravity. In this way, UUVs are extremely susceptible to the impact of ocean currents when performing submarine landing missions, causing UUVs to drift away from the bottom position. Therefore, designing a device that can stably fix the UUV to the seabed is very necessary for the UUV to perform the seabed resident mission. [0003] On the one hand, the seabed mooring device can ensure the stability of the UUV staying on the seabed and prevent the UUV from drifting away from the bottom position due to...
