Embodiment Construction

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

[0016] to combine Figure 1 to Figure 3 , a UUV seabed mooring device of the present invention is composed of four identical parts, and 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 rod 4 and a left anchor Rod 5, right grabbing trowel 3 and left grabbing trowel 6, that is, each part is mainly composed of three mechanisms: hydraulic drive arm, grab trowel and anchor rod; one end of each hydraulic drive arm is hinged on UUV main body 1, The other end is hinged on the middle part 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 retracted, the anchor rod can be pulled upward and inward. One end of each anchor rod It is ...

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 an anchoring device and method for UUV seabed residence. Background technique [0002] When UUV performs tasks such as underwater reconnaissance, submarine ambush, and acting as an underwater communication node, it needs to be stably parked on the seabed to achieve latent operations with high concealment and extremely low energy consumption. In order to make the UUV energy-saving and easy to control when sailing, the UUV is usually designed so that the buoyancy is equal to the gravity. In this way, when the UUV performs a submarine landing mission, it is extremely vulnerable to the influence of ocean currents, causing the UUV to drift away from the bottom position. Therefore, it is very necessary to design a device that can stably fix UUV to the seabed for UUV to perform the task of staying on the seabed. [0003] On the one hand, the seabed mooring device can ensure the stability of the UUV staying on the seabed and prevent ...
