Description

Technical Field

[0001] The invention belongs to the technical field of cables, and in particular relates to a high and low temperature resistant, pressure resistant and corrosion resistant electric wire and cable. Background Art

[0002] Cables are usually rope-like cables twisted together by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering layer. The cable has the characteristics of internal power supply and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of wires and insulation layers, used to connect circuits, electrical appliances, etc. Cables can be divided into DC cables and AC cables according to the system of photovoltaic power stations. According to different uses and use environments, they are classified as follows: DC cables, series cables between components; parallel cables between strings and between strings and DC distribution boxes (combiner boxes); cables between DC distribution boxes and inverters. The above cables are all DC cables, which are mostly laid outdoors and need to be moisture-proof, sun-proof, cold-resistant, heat-resistant, and UV-resistant. In some special environments, they also need to be resistant to chemicals such as acids and alkalis. AC cables, connecting cables from inverter to step-up transformer, connecting cables from step-up transformer to power distribution device, connecting cables from power distribution device to grid or user.

[0003] Existing cables have poor elasticity and poor resilience. When the cables are squeezed, they are prone to bending at the squeezed part, causing the squeezed part to be unable to automatically relax, which in turn causes the squeezed part of the cable to be easily deformed and damaged.

[0004] Therefore, a cable structure resistant to high-frequency bending is needed for engineering use to solve the problem in the prior art that when the cable is squeezed, it is easy to cause bending at the squeezed part, resulting in the squeezed part being unable to automatically relax, and then causing the squeezed part of the cable to be easily deformed and damaged.

[0023] A specific embodiment of the present invention, as Figure 1-Figure 9As shown, a high and low temperature resistant, pressure resistant and corrosion resistant wire and cable is disclosed, including a cable body 100, the outer wall of the cable body 100 is provided with a plurality of arc-shaped elastic sheets 102 distributed in a circle, connecting strips 103 are respectively fixed at both ends of the arc-shaped elastic sheets 102, and two adjacent connecting strips 103 are fixed close to each other on one side, the outer wall of the cable body 100 is provided with a plurality of storage boxes 200 distributed in a circle, the storage box 200 is provided with a first top opening 203 on a side away from the cable body 100, a plurality of evenly distributed squeezing balls 300 are arranged in the storage box 200, a T-bar 201 is arranged in the storage box 200, the T-bar 201 can move through the first top opening 203, an arc block 202 is fixed at one end of the T-bar 201, and the arc block 202 corresponds to the arc-shaped elastic sheet 102.

[0024] As a further solution of the present invention, the arc-shaped surfaces on both sides of the storage box 200 are elastic surfaces.

[0025] By setting the arc surfaces on both sides of the storage box 200 as elastic surfaces, when the T-bar 201 moves to push the squeezing ball 300, the squeezing ball 300 can push the elastic surface to stretch, thereby buffering the movement of the T-bar 201. At the same time, due to the friction between the T-bar 201 and the first top opening 203 and the second top opening 401, it is equivalent to a damper, which can fully buffer the movement of the T-bar 201.

[0026] As a further solution of the present invention, a plurality of buffer blocks 101 distributed in a circumference are provided on the outer side wall of the cable body 100 , and the buffer blocks 101 are fixed to a side surface away from the cable body 100 and a side surface of two adjacent connecting strips 103 .

[0027] By providing the buffer block 101 , when the connection strip 103 is squeezed by force, the buffer block 101 can be deformed to release the force, thereby protecting the cable body 100 .

[0028] The buffer block 101 is made of rubber.

[0029] As a further solution of the present invention, a high and low temperature resistant layer 700 is fixed to the outer wall of the cable body 100, a corrosion resistant layer 701 is fixed to the outer wall of the high and low temperature resistant layer 700, the buffer block 101 is fixed to the outer wall of the corrosion resistant layer 701 near one side of the cable body 100, and the storage box 200 is fixed to the outer wall of the corrosion resistant layer 701 near one side of the cable body 100.

[0030] By providing the high and low temperature resistant layer 700 , the cable body 100 can be resistant to high and low temperatures, and by providing the corrosion resistant layer 701 , the cable body 100 can be resistant to corrosion.

[0031] This solution has the following working process: when the cable body 100 is impacted by external force and the impacted position is the position of the arc-shaped elastic sheet 102, the arc-shaped elastic sheet 102 is deformed to buffer and release the pressure, thereby protecting the cable body 100. When the pressure is large, the arc-shaped elastic sheet 102 cannot relieve the pressure. At this time, the arc-shaped elastic sheet 102 is deformed to relieve part of the force. The deformation of the arc-shaped elastic sheet 102 pushes the pushing column 500 to move, the pushing column 500 pushes the arc block 202 to move, the arc block 202 pushes the T-bar 201 to move, the movement of the T-bar 201 pushes the squeezing ball 300 to move, and the squeezing ball 300 pushes the arc surface inside the storage box 200 to stretch, so that another part of the force is relieved.

[0032] When the impacted position is at the connection strip 103 , the buffer block 101 is deformed to release the force.

[0033] When the impacted position is at the connection ring 602, part of the pressure pushes the vertical elastic piece 603 to deform and release the force, while another part of the force pushes the connection ring 602 to rotate, so that the force is released by rotation.

[0034] According to the above working process, it can be known that: by setting the buffer block 101, when the connecting strip 103 is subjected to pressure, the buffer block 101 can disperse and relieve the pressure; by setting the arc-shaped elastic sheet 102, when the arc-shaped elastic sheet 102 is subjected to pressure, the arc-shaped elastic sheet 102 can be deformed to relieve the force; by setting the arc block 202, T-bar 201, squeezing ball 300 and storage box 200, the unrelieved force of the arc-shaped elastic sheet 102 can be further relieved, so that the pressure on the arc-shaped elastic sheet 102 can be relieved, thereby avoiding deformation and damage at the squeezed position when the cable body 100 is squeezed.

[0035] By setting up the vertical elastic sheet 603, when the connecting ring 602 receives pressure, the vertical elastic sheet 603 can be deformed to relieve the force, and at the same time, the connecting ring 602 can be rotated to further relieve the remaining force, thereby relieving the pressure on the connecting ring 602 and further avoiding deformation and damage at the extrusion position.

[0036] As a further solution of the present invention, a plurality of evenly distributed stoppers 600 are fixed to the outer wall of the cable body 100 , and a locking ring 601 is movably engaged in the stopper 600 .

[0037] By providing the limiter 600 , the position of the locking ring 601 can be movably limited, thereby facilitating the rotation of the locking ring 601 .

[0038] As a further solution of the present invention, a connecting ring 602 is fixed to the outer side wall of the locking ring 601 , and a plurality of vertical elastic pieces 603 distributed in a circumference are fixed to the outer side wall of the connecting ring 602 .

[0039] By setting up the vertical elastic sheet 603, when the connecting ring 602 is squeezed, the force can push the vertical elastic sheet 603 to deform and release the force, and at the same time drive the locking ring 601 to rotate to release the force, so that the force acting on the connecting ring 602 can be released by the rotation of the connecting ring 602 and the deformation of the vertical elastic sheet 603.

[0040] As a further solution of the present invention, the buffer block 101 is a trapezoidal structure.

[0041] The buffer block 101 is set to a trapezoidal structure, so that when the buffer block 101 is deformed, the force can be transferred to the surface of the corrosion-resistant layer 701 for removal.

[0042] As a further solution of the present invention, a plurality of push posts 500 distributed in a circumference are fixed to the inner side wall of the arc-shaped elastic sheet 102 , and the push posts 500 are cylindrical structures.

[0043] By setting the pushing column 500, the arc elastic sheet 102 can push the pushing column 500 to move after deformation, so that the pushing column 500 pushes the arc block 202 to move, so that the T-bar 201 pushes the squeezing ball 300, and the force that is not completely released by the arc elastic sheet 102 is released.

[0044] As a further solution of the present invention, a plurality of C-shaped frames 400 distributed in a circle are fixed to the outer wall of the corrosion-resistant layer 701 , and a second top opening 401 is opened on a side of the C-shaped frame 400 away from the cable body 100 , and the T-shaped rod 201 passes through the second top opening 401 .

[0045] By providing the C-shaped frame 400 and the second top opening 401 , the position of the T-shaped bar 201 can be further limited.

[0046] As a further solution of the present invention, the arc block 202 is a semi-cylindrical structure.

[0047] By providing the arc block 202 , when the pushing column 500 pushes the arc block 202 , the arc block 202 can push the T-shaped rod 201 to move.

[0048] In summary: when the cable body 100 is impacted by external force and the impacted position is the position of the arc-shaped elastic sheet 102, the arc-shaped elastic sheet 102 is deformed to buffer and release the pressure, thereby protecting the cable body 100. When the pressure is large, the arc-shaped elastic sheet 102 cannot relieve the pressure. At this time, the arc-shaped elastic sheet 102 is deformed to relieve part of the force. The deformation of the arc-shaped elastic sheet 102 pushes the pushing column 500 to move, the pushing column 500 pushes the arc block 202 to move, the arc block 202 pushes the T-bar 201 to move, the movement of the T-bar 201 pushes the squeezing ball 300 to move, and the squeezing ball 300 pushes the arc surface inside the storage box 200 to stretch, so that another part of the force is relieved.

[0049] When the impacted position is at the connection strip 103 , the buffer block 101 is deformed to release the force.

[0050] When the impacted position is at the connection ring 602, part of the pressure pushes the vertical elastic piece 603 to deform and release the force, while another part of the force pushes the connection ring 602 to rotate, so that the force is released by rotation.

[0051] The cable body 100, the high and low temperature resistant layer 700 and the corrosion resistant layer 701 can all be purchased from the market, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
