Technical Field

[0001] The present invention relates to the field of cable technology, and in particular to a new energy storage cable with a steering adjustment function. Background Art

[0002] New energy storage cables are widely used in various new energy storage scenarios, such as battery energy storage power stations, power battery systems of new energy vehicles, solar and wind energy storage devices, etc., providing reliable power transmission guarantee for the development of the new energy industry; the characteristics of new energy storage cables include: high current carrying capacity, good temperature resistance, excellent anti-aging and weather resistance, low resistance and reliable insulation performance;

[0003] Energy storage cables are usually thick and heavy due to their large current carrying capacity and high performance requirements, which makes installation more difficult. In addition, in environments with limited space or complex wiring, it is difficult for workers to bend and turn the cables when installing energy storage cables. At the same time, flexible cables need to be fixed to keep the cables in a bent state, which causes limitations.

[0004] Therefore, we propose a bending resistance testing device for cables. Summary of the invention

[0012] By arranging the first block and the second block on both sides of the bending sleeve, the first block and the second block respectively pull and push the two bending sleeves, so that the bending sleeve drives the cable to bend and turn, and the angle of bending and turning is controlled by rotating the first adjusting ring and the second adjusting ring. At the same time, the first block is arranged in an arc shape, so that during the bending process of the cable, the first block guides the bending and turning of the cable, that is, makes the bending and turning of the cable more uniform.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1: Refer to the attached drawings of the specification Figure 1 , 2 and 3, a new energy storage cable with a steering adjustment function, comprising:

[0029] A battery cell, an insulating layer 1 and a terminal 11; a bending sleeve 2 is arranged outside the insulating layer 1; the bending sleeves 2 are connected to each other;

[0030] Tensile mechanisms and pushing mechanisms are respectively arranged on both sides of the bending sleeve 2; the tensile mechanism pulls two adjacent bending sleeves 2 towards each other on one side of the bending sleeve 2; the pushing mechanism pushes two adjacent bending sleeves 2 in the opposite direction on the side away from the tensile mechanism, so that the bending sleeve 2 bends the cable.

[0031] In the present invention, the tensile mechanism includes a first block 3 and a first adjusting ring 31; a first installation groove 32 is opened at one end of the bending sleeve 2, and a first receiving groove 33 is opened at the other end of the bending sleeve 2; one end of the first block 3 is rotatably connected in the first installation groove 32; the other end of the first block 3 is slidably connected in the first receiving groove 33 of the adjacent bending sleeve 2; the first adjusting ring 31 is rotatably connected outside the bending sleeve 2; the inner wall of the first adjusting ring 31 is provided with helical tooth patterns; both sides of the first block 3 are arranged in a helical tooth shape meshing with the first adjusting ring 31;

[0032] The driving mechanism includes the second block 34 and the second adjusting ring 35; both ends of the bending sleeve 2 are respectively provided with a second installation groove 36 and a second receiving groove 37; the second installation groove 36 and the first receiving groove 33 are located at the same end of the bending sleeve 2; the second receiving groove 37 and the first installation groove 32 are located at the same end of the bending sleeve 2; the second adjusting ring 35 is rotatably connected to the outer side of the end of the bending sleeve 2 far from the first adjusting ring 31; the inner wall of the second adjusting ring 35 is provided with helical teeth; both sides of the second block 34 are arranged in a helical shape meshing with the second adjusting ring 35.

[0033] In the present invention, both the first block 3 and the second block 34 are arranged in an arc shape; the first receiving groove 33 and the second receiving groove 37 are also arranged in an arc shape.

[0034] In the present invention, when the staff installs the cable and bends the cable, first hold two adjacent bending sleeves 2, and then rotate the first adjusting ring 31 and the second adjusting ring 35 simultaneously, and the rotation directions of the first adjusting ring 31 and the second adjusting ring 35 are opposite; during the rotation of the first adjusting ring 31, the first block 3 is driven to move towards the inside of the first receiving groove 33 through the helical teeth, so that both ends of the first block 3 pull the two bending sleeves 2 towards the inside, and at the same time, during the rotation of the second adjusting ring 35, the second block 34 is driven to move outwards from the second receiving groove 37 through the helical teeth, so that the second block 34 pushes the other side of the two bending sleeves 2. Therefore, in the present invention, the cable between the two bending sleeves 2 is bent by pulling and pushing on both sides of the bending sleeve 2 at the same time. The more the first adjusting ring 31 and the second adjusting ring 35 rotate, the greater the degree of cable bending;

[0035] In the present invention, the first block 3 and the second block 34 are arranged in an arc shape. Therefore, during the bending of the cable, after the cable contacts the arc-shaped first block 3 and bends along it, the bending of the cable can be made more uniform, reducing local stress concentration, bending more evenly, and reducing the risk of cable damage; at the same time, the arc-shaped first block 3 can provide better guidance for the bending of the cable, ensuring that the bending direction and degree are more in line with expectations;

[0036] In the present invention, by arranging the first block 3 and the second block 34 on both sides of the bending sleeve 2, the first block 3 and the second block 34 respectively pull and push the two bending sleeves 2, so that the bending sleeve 2 drives the cable to bend and turn, and the angle of bending and turning is controlled by rotating the first adjusting ring 31 and the second adjusting ring 35. At the same time, the first block 3 is arranged in an arc shape, so that during the bending of the cable, the first block 3 guides the bending and turning of the cable, that is, makes the bending and turning of the cable more uniform.

[0037] Embodiment 2: On the basis of Embodiment 1, refer to the attached drawings of the specification Figure 3 、 4In the present invention, the outer side of the insulating layer 1 is evenly fixedly connected with connecting rings 4; the connecting ring 4 is provided with a first annular groove 41.

[0038] In the present invention, a second annular groove 42 is provided on the inner wall of the bending sleeve 2; a clamping block 43 is evenly rotatably connected in the second annular groove 42, and an extrusion ring 44 is rotatably connected in the second annular groove 42; a connecting rod 45 is hinged between the extrusion ring 44 and the clamping block 43.

[0039] In the present invention, a through groove 5 is provided on the bending sleeve 2; the through groove 5 is connected to the second annular groove 42, and a fixed block 51 is slidably connected in the through groove 5; the fixed block 51 is fixedly connected to the extrusion ring 44, and the sliding track of the fixed block 51 is an arc shape.

[0040] In the present invention, the staff moves the fixing block 51 to make the fixing block 51 slide in the through groove 5. During the sliding process, the fixing block 51 drives the extrusion ring 44 to rotate, so that the extrusion ring 44 pushes the connecting rod 45, so that the engaging block 43 rotates into the first annular groove 41, and the engaging block 43 engages the connecting ring 4 and the bending sleeve 2, so that the bending sleeve 2 is fixed on the insulating layer 1 of the cable, and the bending sleeve 2 will not slide, which will affect the bending of the cable.

[0041] In the present invention, an ejection groove 6 is provided on the bending sleeve 2; one end of the ejection groove 6 passes through the bending sleeve 2, and the other end is connected to the No. 1 receiving groove 33; an ejection block 61 is slidably connected in the ejection groove 6; the lower end of the ejection block 61 is located in the No. 1 receiving groove 33, and the end of the ejection block 61 close to the No. 1 block 3 is set in an oblique shape.

[0042] In the present invention, an ejection groove 6 is provided on the bending sleeve 2, so when the cable is bent, the No. 1 block 3 moves in the No. 1 receiving groove 33. When the No. 1 block 3 moves to the end of the No. 1 receiving groove 33, the front end of the No. 1 block 3 presses the inclined end surface of the ejection block 61, so that the ejection block 61 moves upward and extends out of the ejection groove 6. When the staff sees the ejection block 61 extending out, they know that the No. 1 block 3 has moved to the maximum distance in the No. 1 receiving groove 33, that is, the bending sleeve 2 drives the cable to bend at the maximum angle.

[0043] In the present invention, three bending sleeves 2 form a group, and the three bending sleeves 2 can bend the cable between any two, thereby increasing the bending angle of the cable in the present invention;

[0044] In the present invention, by providing an ejection groove 6 and an ejection block 61 on the bent sleeve 2, when the angles at which the two bent sleeves 2 bend the cable reach the maximum, the first block 3 pushes the ejection block 61 to move upward, exposing the ejection groove 6, thereby reminding the staff to prevent the situation where, after the angles at which the bent sleeve 2 bends the cable reach the maximum, the staff continues to rotate the first adjusting ring 31 and the second adjusting ring 35, resulting in wear of the teeth between the first block 3, the second block 34, the first adjusting ring 31, and the second adjusting ring 35.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed; the scope of the present invention claimed is defined by the appended claims and their equivalents.
