Description

Underwater vehicle cable protection device

Technical Field

The utility model relates to an underwater robot technical field, concretely relates to underwater vehicle cable protection device.

Background

Most underwater vehicles (or underwater robots, ROVs) drag through long cables at present, one end of each cable is connected with the underwater vehicle, the other end of each cable is connected with water surface or on-shore equipment, and communication or power supply and the like are completed through the cables. And after the underwater vehicle returns to the water surface, an operator can drag the underwater vehicle on a ship or on the shore and lift the underwater vehicle out of the water surface to recover the equipment, the process is generally finished by pulling the cable, and when the cable is long, the cable winder can be matched, and the process can be finished through the cable winder. After the underwater vehicle leaves the water surface, the cable needs to bear the whole weight, and the joint of the cable and the underwater vehicle is easy to be broken due to local stress concentration after multiple operations. Therefore, there is a need for a cable protection device for underwater vehicles, especially for protecting the cable and equipment connection interface.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an underwater vehicle cable protection device solves current cable and underwater vehicle junction and easily draws cracked problem because of carrying many times.

In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides an underwater vehicle cable protection device which characterized in that: including the fixed plate, the fixed plate cup joints in the knot department of buoyancy cable, and the fixed plate is fixed through the rubber coating with the knot, and the outer parcel of rubber coating has the layer of moulding plastics, and the fixed plate is detained through rock climbing and is connected with this body of ware of diving under water.

According to a further technical scheme, the fixing plate is a stainless steel plate body, a round hole is formed in the fixing plate, a fixing column extends outwards from the end of the fixing plate, and the fixing column is sleeved on the buoyancy cable.

The further technical scheme is that the injection molding layer is coaxial with the buoyancy cable, an anti-skidding groove is formed in the outer side wall of the injection molding layer, and a net tail is arranged at the top of the injection molding layer.

The working principle is as follows: a rope knot is tied on the buoyancy cable, a fixing plate is sleeved, the fixing plate and the rope knot are solidified together through a rubber coating process, and an injection molding layer is wrapped outside the rubber coating layer through an injection molding process after forming. When the underwater vehicle is used, the buoyancy cable is connected with the underwater vehicle, and the fixing plate is connected with the underwater vehicle through the rock climbing buckle. When the underwater vehicle is pulled out of the water surface, the fixed plate can rotate in a small range, but the buoyancy cable between the underwater vehicle and the fixed plate has small deformation, so that the connection part of the flotation cable and the underwater vehicle is small in stress and not easy to break. At the moment, the bearing force is mainly the buoyancy cable from the fixing plate to the part above the water surface, and due to the arrangement of the knot, the pulling force can be uniformly distributed to the wire skin of the cable and the Kevlar woven net arranged inside, so that the specification of the buoyancy cable can be conveniently designed or selected.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a simple structure's underwater vehicle cable protection device, through cup jointing the fixed plate in buoyancy cable knot department to it is fixed through the rubber coating layer, further fixed through the layer of moulding plastics, when pulling out the surface of water with the underwater vehicle, the buoyancy cable that is in between underwater vehicle and the fixed plate warp for a short time, and flotation cable is little with the underwater vehicle junction atress like this, difficult fracture.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1-3 show a cable protection device for an underwater vehicle, comprising a fixing plate 1. The fixed plate 1 is a stainless steel plate, is strong in corrosion resistance and high in strength, and is provided with a round hole in the plate surface, and the round hole is used for fixing the rock climbing buckle and the underwater vehicle body. 1 lateral wall of fixed plate is toward extending outward there are two fixed columns 101, it has the through-hole to open on the fixed column 101, after calculation and analysis, can make an knot on 2 appointed length of buoyancy cable, overlap fixed plate 1 outside 2 of buoyancy cable in the knot top, fixed plate 1 is fixed through adhesive tape 4 with knot 3, the outer parcel of adhesive tape 4 has the layer of moulding plastics, the layer of moulding plastics is for 2 coaxial settings with buoyancy cable, be provided with anti-skidding slot 5 on the outer lateral wall of the layer of moulding plastics, it is provided with net tail 6 to mould plastics a layer top. The antiskid groove 5 is convenient to carry by hand, and the net tail 6 can resist impact and stress concentration, so that the connection buoyancy cable between the fixing plate and the equipment can be further ensured not to be broken under sudden stress in the lifting process or working process.

A rope knot 3 is tied at the designated position of the buoyancy cable 1, a fixing plate 1 is sleeved at the rope knot 3, the fixing plate 1 and the rope knot 3 are solidified together by using a rubber coating process, and an injection molding layer is wrapped outside a rubber coating layer 4 by using an injection molding process after molding. When the underwater vehicle is used, the buoyancy cable 2 is connected with the underwater vehicle, and the fixing plate 1 is connected with the underwater vehicle through the rock climbing buckle. When the underwater vehicle is pulled out of the water surface, the fixing plate 1 rotates in a small range, but the buoyancy cable between the underwater vehicle and the fixing plate 1 deforms little, so that the connection part of the flotation cable 2 and the underwater vehicle is stressed little and is not easy to break. At the moment, the force bearing is mainly the buoyancy cable 2 from the fixing plate 1 to the part on the water surface, and due to the arrangement of the knot 3, the pulling force can be uniformly distributed to the wire skin of the cable and the Kevlar woven net arranged inside, so that the service life of the buoyancy cable 2 can be greatly prolonged. In addition, because the tension is uniformly distributed, the underwater vehicle can be subjected to stress analysis according to the size and the quality of the underwater vehicle, the size of a sheath of the buoyancy cable, the size of a Kevlar woven net wrapping a wire core and the like can be designed and selected after tension data are obtained, and the buoyancy cable with longer service life is further obtained.
