Technical Field

The utility model relates to the technical field of water cables, in particular to an impact-resistant low-water-resistance water cable.

Background

The cable is a product used to transmit electricity and to transmit signals or to perform electromagnetic energy conversion.

Detailed Description

The following description of the technical solutions in the embodiments of the present utility model will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the prior art, each wire 1 is composed of an internal cell and a wire 1, and the key of transmitting power and signals is that the internal cell of the wire 1 is connected with the wire. For use on the sea floor, the main damage to its wires 1 is the impact of water resistance pressure. Thus, there is a need for targeted improvement of the water cable construction for its specific use.

Referring to fig. 1 to 3, the utility model is composed of an inner wire 1 and an outer sheath layer 2, wherein the wire 1 and the outer sheath layer 2 are connected through a plurality of connecting pieces 3, the outer sheath layer 2 is arranged in a quadrilateral diamond shape, and the outer sheath layer 2 and the axis of the wire 1 are positioned on the same axis.

This design mainly consists in the further protection of the inner conductor 1 by the outer jacket layer 2. The wire 1 and the outer sheath layer 2 are integrally formed through the connecting pieces 3, a certain gap exists between the wire 1 and the outer sheath layer 2 through the connecting mode of the plurality of connecting pieces 3 at intervals, meanwhile, the connecting pieces 3 and the outer sheath layer 2 are made of rubber materials, the outer sheath layer 2 and the axis of the wire 1 are in the same axis, so that internal and external stress is uniform, and the structure is firm and stable during connection. The main principle is as follows: under the water resistance pressure, the impact force of the water resistance pressure impact the outer sheath layer 2, the outer sheath layer 2 is extruded to the inner gap under the elastic action, so that the force unloading effect is achieved, and the impact force of the internal lead 1 can be reduced greatly.

Specifically, the outer sheath layer 2 is set to be diamond-shaped, preferably to be diamond-shaped with four sides, the corresponding connecting pieces 3 with transverse sections are four sides matching the diamond-shaped sides of the four sides and more than a multiple of four sides, and the connecting pieces 3 on each side are arranged at intervals. This structural arrangement is such that a gap for buffering the hydraulic shock exists between each adjacent connection member 3 while the wire 1 is connected with the outer sheath layer 2. The number of the connecting pieces 3 is multiple of four, so that one connecting piece is uniformly arranged on each edge. The cable mainly has the advantages that the length of the actual water cable is too large, and the number of the applied connecting pieces is also required to be a certain number, so that the connection fixation of the wires and the outer sheath layer is ensured, and the impact resistance can be achieved for the external water resistance pressure.

Meanwhile, due to the design of the four-side diamond, when the water resistance pressure impacts the outer sheath layer 2 along one direction, partial pressure can also realize force unloading along the edge in a guiding mode, so that the impact resistance of the water cable can be improved to a certain extent. While the edge shape of the four-sided diamond is impacted by water pressure in one direction, the stress conditions of all parts of each side are different, so that the cable on the water can have a rotary shaft action to realize impact force unloading. The four-sided diamond can be a regular four-sided diamond or a symmetrical four-sided diamond, and the difference is that the rotation amplitude of the rotary shaft action is different.

The principle of realizing force unloading through the assembly structure of the outer sheath layer 2 and the lead 1 and the shape setting of the outer sheath layer 2 is adopted.

The expansibility is mainly shown with reference to figures 1 and 3 or figures 2 and 3, each edge of the outer sheath layer 2 is composed of two layers of rubber sleeves 4, two ends between the two layers of rubber sleeves 4 are fixed, and the fixing mode can be realized by an adhesive mode. The middle part of the two layers of rubber sleeves 4 is provided with a gap, the gap is the largest at the right center of the two layers of rubber sleeves 4, and the gap is gradually reduced along the directions of two sides at the right center. The effect of water resistance impact force can be achieved on the outer sheath layer 2 by the aid of the design, the size of gaps between the middle of the two layers of rubber sleeves 4 and the two sides is different, the rubber sleeves 4 of the outer surface layer can be extruded to form an radian by components under the impact force of the water resistance in one direction, water pressure can flow along the radian, and compared with straight-face performance, the effect of impact resistance is better.

When the impact resistance of the water cable is improved, the shaking degree of the water cable in the same horizontal direction is effectively relieved due to the clamping of the unloading force, and the unloading force is in all directions, so that the water cable shakes in a range close to a circle. Meanwhile, the direction of the unloading force is realized in a certain guiding mode, namely, the impact of the water resistance does not totally impact the cable on water to fix one direction, but part of the direction is scattered, so that the unloading force effect is realized. Therefore, the shaking amplitude degree of the water cable caused by hydraulic impact and the damage degree to the inner wire of the water cable body can be greatly reduced.

The present utility model is not limited to the preferred embodiments, but is intended to be limited to the following description, and any modifications, equivalent changes and variations in light of the above-described embodiments will be apparent to those skilled in the art without departing from the scope of the present utility model.
