Description

Technical Field

[0001] The utility model relates to the technical field of cable protection devices, in particular to a cable connection protection device for electric power engineering. Background Art

[0002] A cable is a conductor used to transmit electrical energy, electrical signals or optical signals. There are many types of cables, including power cables, control cables, compensation cables, etc. In power engineering, cables are usually wired to ensure that multiple cables are connected. At the same time, after the cables are wired, they need to be protected by protective devices to avoid damage to the cables. However, existing cable protection devices can only fix two cables and cannot buffer the tension generated by the outside, so that when the tension is large, the connection is easily pulled, causing damage to the connection.

[0003] In order to address the above problems, a Chinese patent with an existing announcement number of CN215732429U proposes a power engineering cable wiring protection device, which fixes the cable by two sets of relatively arranged fixing devices. A set of fixing devices located on the outside is slidably connected to the protective shell, and the bottom of this set of fixing devices is connected to the protective shell through a second spring. When the cable moves outward due to external force, the cable pulls the fixing device located on the outside to slide along the T-slot and squeeze the second spring, thereby avoiding the pulling force from damaging the cable connection.

[0004] However, although the above-mentioned power engineering cable wiring protection device can slide along the T-slot through the outer fixing device and squeeze the second spring to buffer the cable, thereby avoiding the phenomenon of pulling force damaging the cable connection, the power engineering cable wiring protection device needs to reserve part of the cable between the outer fixing device and the inner fixing device. When the outer fixing device slides along the T-slot, this part of the cable will be entangled and collided with other electrical equipment inside the protective shell, thereby causing damage to the internal electrical equipment. Therefore, the utility model provides a cable wiring protection device for power engineering to meet the needs. Utility Model Content

[0034] Specifically, first, the cable is fixed by two clamping members 3. When the cable moves, the cable drives the pulley 9 to rotate, the pulley 9 drives the first rotating shaft 7 to rotate, the first rotating shaft 7 adjusts the bevel gear four 65 to rotate, the bevel gear four 65 drives the bevel gear three 63 to rotate, the bevel gear three 63 drives the bevel gear two 62 to rotate through the second rotating shaft 64, the bevel gear two 62 drives the bevel gear one 20 to rotate through the connecting rod 61, the bevel gear one 20 drives the double-headed screw 4 to rotate, and the double-headed screw 4 drives the two relatively arranged clamping members 3 to move relative to each other, so that the two clamping members 3 are in contact with each other. The clamping force of the cable is improved, which prevents the cable from moving when pulled by external force, ensures the stability of the cable interface, and the overall device structure is simple, does not need to reserve extra cables, avoids the phenomenon of cables colliding and entangled with electrical equipment in the protective shell 1, and also avoids damage to the electrical equipment. It solves the problem that the existing cable wiring protection device needs to reserve part of the cable in the protective shell 1, and this part of the cable will be entangled and collided with other electrical equipment inside the protective shell 1 when the outer fixing device slides, thereby causing damage to the internal electrical equipment.

[0035] It should be noted that the protective shell 1 can be a protective box, equipment box, etc. in the prior art. Two cables extend into the protective shell 1 and are then clamped and fixed by two sets of clamping mechanisms. When the clamping mechanism fixes the cable, the drive assembly 6 does not contact the double-headed screw 4, or the pulley 9 does not contact the cable. At the same time, the pulley 9 is installed at the connection between the cable and the protective shell 1, so that it can be ensured that the pulley 9 can continue to contact the cable.

The rubber pad 17 can prevent the clamping end 32 from causing damage to the cable when clamping, and plays a buffering role. The anti-slip groove 18 can increase the friction between the rubber pad 17 and the cable, so that the clamping member 3 can clamp the cable more stably.

It should be noted that the fixed rod 611 is penetrated and rotatably arranged on the support plate 2 15.

[0040] like Figure 6 As shown, in this embodiment, protrusions 13 are evenly distributed on the outside of the pulley 9. Specifically, the protrusions 13 can increase the friction between the pulley 9 and the cable, thereby ensuring the rotation of the pulley 9.

[0041] Working principle:

[0042] First, the telescopic rod 612 is controlled to be located at the position of the fixed rod 611 through the positioning pin 10 and the positioning hole 11, so that the telescopic rod 612 controls the distance between the bevel gear 2 62 and the bevel gear 1 20, and then the double-headed screw 4 is adjusted by the handle 12 to drive the clamping part 3 to clamp and fix the cable. When the cable moves, the cable drives the pulley 9 to rotate, the pulley 9 drives the first rotating shaft 7 to rotate, the first rotating shaft 7 adjusts the bevel gear 4 65 to rotate, the bevel gear 4 65 drives the bevel gear 3 63 to rotate, the bevel gear 3 63 drives the bevel gear 2 62 to rotate through the second rotating shaft 64, the bevel gear 2 62 drives the bevel gear 1 20 to rotate through the connecting rod 61, and the bevel gear 1 20 drives the double-headed screw 4 The double-headed screw rod 4 rotates and drives the two relatively arranged clamping parts 3 to move relative to each other, thereby enhancing the clamping force of the two clamping parts 3 on the cable, avoiding the cable to move when being pulled by external force, ensuring the stability of the cable interface, and the overall device structure is simple, without the need to reserve extra cables, thus avoiding the phenomenon of cables colliding and entangled with electrical equipment in the protective shell 1, and also avoiding damage to the electrical equipment, solving the problem that the existing cable wiring protection device needs to reserve part of the cables in the protective shell 1, and this part of the cables will be entangled and collided with other electrical equipment inside the protective shell 1 when the outer fixing device slides, thereby causing damage to the internal electrical equipment.
