Description

Technical Field

[0001] This utility model relates to the field of power construction technology, and in particular to a cable protection device for power construction sites. Background Technology

[0002] Currently, power construction refers to a series of operational activities involving the construction, installation, commissioning, maintenance, repair, and renovation of facilities and equipment related to all aspects of the power system, including power generation, transmission, substation, distribution, and consumption. These activities include the construction of power plants, the erection of transmission lines, the installation and commissioning of substations, and the installation and maintenance of distribution equipment. The aim is to ensure the safe, stable, and reliable operation of the power system and to provide a continuous and stable power supply to society.

[0003] At the construction site, due to the long length of the cable, it cannot be installed in one go. When the cable is moved, it will twist due to friction with the ground. Because the cable is long, it cannot automatically straighten itself after twisting. Excessive twisting of the cable will make the heat dissipation channel of the cable irregular, affecting the heat dissipation. During power transmission, the cable will heat up due to resistance. If the heat dissipation is not good, the cable temperature will rise. Long-term high temperature will accelerate the aging of the cable insulation layer and reduce the service life of the cable. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cable protection device for power construction sites.

[0005] This utility model is achieved by the following technical solution: a cable protection device for power construction sites, including a cable, on which a protective component is sleeved to prevent the cable from rotating too much, and a fixing component is installed on the protective component to allow the protective component to be quickly fixed to the cable, the protective component including two fixing half rings sleeved on the cable, and an anti-deviation plate is fixedly installed on one side of each of the two fixing half rings.

[0006] With the above technical solution, when installing the protective components, simply close the two fixed half-rings around the cable and fix them with the fixing components. The anti-deviation plate can limit the torsion angle of the cable and prevent it from rotating excessively.

[0007] As a further improvement to the above solution, rubber half-rings are fixedly installed on the inner ring surfaces of both fixed half-rings, and the inner ring surfaces of both rubber half-rings are in contact with the outer surface of the cable.

[0008] Through the above technical solution, the rubber semi-ring increases the friction between the protective component and the cable, enabling the protective component to be installed more securely on the cable. At the same time, the rubber semi-ring has a certain degree of elasticity, which can prevent damage to the outer surface of the cable.

[0009] As a further improvement to the above solution, a rotating shaft is provided at the joint of the two fixed half-rings, and the two fixed half-rings are rotated and engaged through the rotating shaft.

[0010] The above technical solution allows the rotating shaft to be conveniently positioned so that the two fixed semi-rings can open and close around the cable, facilitating the installation and removal of protective components and improving operational convenience.

[0011] As a further improvement to the above solution, the fixing component includes a limiting plate fixedly installed on one of the fixing half rings. The limiting plate is concave and has a fixing groove that penetrates it on one side. A fixing block is provided inside the fixing groove. A fixing strip is fixedly installed on the other fixing half ring, and one end of the fixing strip passes through the limiting plate.

[0012] With the above technical solution, during installation, the fixing strip is passed through the groove of the limiting plate itself, and then fixed by the fixing block inside the fixing groove, so as to achieve a quick connection of the two fixing half rings, thereby fixing the protective component to the cable.

[0013] As a further improvement to the above solution, a plurality of insertion slots are provided on one side of the fixing strip, and one side of the fixing block is located inside the adjacent insertion slot.

[0014] Through the above technical solution, the fixing position of the fixing block can be adjusted according to the actual situation of the cable, so that the protective component can better adapt to cables of different specifications and enhance the versatility of the device.

[0015] As a further improvement to the above solution, limit holes are provided on both sides of the top of the limit plate, and limit posts are provided inside the two limit holes. Limit plates are fixedly installed at the bottom of the two limit posts. One end of the two limit posts passes upward through the limit hole. Pull plates are fixedly installed at the top of the two limit posts. The top of the fixing block is fixedly installed with the bottom of the pull plate. Push springs are sleeved on the two limit posts. The two ends of the two push springs abut against the top of the adjacent limit plate and the inner wall of the limit hole, respectively.

[0016] Through the above technical solution, the push spring plays a role in buffering and assisting in fixing during the installation and removal of the protective components. During installation, the elastic force of the push spring makes the fixing block insert more tightly into the insertion slot, enhancing the fixing effect; during removal, lifting the pull plate compresses the push spring, allowing the fixing block to detach from the insertion slot, facilitating the removal of the protective components.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention effectively limits the cable twisting angle and enables rapid installation and fixation of the protective component by setting up a protective component and a fixing component. During installation, the two fixing half-rings are opened and wrapped around the cable, then secured using the fixing component; the operation is simple and convenient. The cooperation of the anti-deviation plate and rubber half-rings in the protective component, and the limiting post, limiting plate, and push spring in the fixing component, enhances the stability of the connection between the protective component and the cable, effectively preventing excessive cable twisting and ensuring normal heat dissipation and service life of the cable.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figures 1-3 This embodiment of a cable protection device for power construction sites includes a cable 1, on which a protective component is fitted to prevent the cable 1 from rotating too much, and a fixing component is installed on the protective component to allow the protective component to be quickly fixed to the cable 1.

[0026] When installing the protective components, simply close the two fixed half-rings 201 around the cable 1 and fix them with the fixing components. The anti-deviation plate 202 can limit the torsion angle of the cable 1 and prevent it from rotating excessively.

[0027] The protective assembly includes two fixed half-rings 201 sleeved on the cable 1. Anti-deviation plates 202 are fixedly installed on one side of each of the two fixed half-rings 201. Rubber half-rings 4 are fixedly installed on the inner ring surface of each of the two fixed half-rings 201. The inner ring surface of each of the two rubber half-rings 4 is in contact with the outer surface of the cable 1. A rotating shaft is provided at the contact point of the two fixed half-rings 201, and the two fixed half-rings 201 are rotated and engaged through the rotating shaft.

[0028] The rubber semi-ring 4 increases the friction between the protective component and the cable 1, allowing the protective component to be installed more securely on the cable 1. At the same time, the rubber semi-ring 4 has a certain degree of elasticity, which can prevent damage to the outer surface of the cable 1.

[0029] The rotating shaft design facilitates the opening and closing of the two fixed semi-rings 201 around the cable 1, making it easy to install and remove the protective components and improving operational convenience.

[0030] The fixing assembly includes a limiting plate 301 fixedly installed on one of the fixing half rings 201. The limiting plate 301 is concave and has a fixing groove that passes through it on one side. A fixing block 302 is provided inside the fixing groove. A fixing strip 303 is fixedly installed on the other fixing half ring 201. One end of the fixing strip 303 passes through the limiting plate 301.

[0031] During installation, the fixing strip 303 is passed through the groove of the limiting plate 301, and then fixed by the fixing block 302 inside the fixing groove to achieve a quick connection of the two fixing half rings 201, thereby fixing the protective component to the cable 1.

[0032] The fixing strip 303 has multiple insertion slots on one side, and the fixing block 302 has one side located inside the adjacent insertion slot.

[0033] Multiple plug slots allow for adjustment of the fixing position of the fixing block 302 according to the actual situation of the cable 1, enabling the protective component to better adapt to cables 1 of different specifications and enhancing the versatility of the device.

[0034] Limiting holes are provided on both sides of the top of the limiting plate 301. Limiting posts 5 are provided inside the two limiting holes. Limiting plates 6 are fixedly installed at the bottom of the two limiting posts 5. One end of the two limiting posts 5 passes upward through the limiting hole. Pulling plates 7 are fixedly installed at the top of the two limiting posts 5. The top of the fixing block 302 is fixedly installed with the bottom of the pulling plate 7. Pushing springs 8 are sleeved on the two limiting posts 5. The two ends of the two pushing springs 8 abut against the adjacent limiting plate 6 and the top of the inner wall of the limiting hole, respectively.

[0035] The push spring 8 acts as a buffer and auxiliary fixation during the installation and removal of the protective assembly. During installation, the elastic force of the push spring 8 makes the fixing block 302 insert more tightly into the insertion slot, enhancing the fixing effect; during removal, lifting the pull plate 7 compresses the push spring 8, allowing the fixing block 302 to disengage from the insertion slot, facilitating the removal of the protective assembly.

[0036] The implementation principle of a cable protection device for power construction sites in this application embodiment is as follows: When installing the protection component, first open the two fixing half rings 201 around the cable 1 so that the rubber half rings 4 fit against the outer surface of the cable 1, lift the pull plate 7, push the spring 8 to be compressed, then pass the fixing strip 303 through the groove of the limiting plate 301 itself, select a suitable insertion slot, align the fixing block 302 with the insertion slot, release the pull plate 7, push the spring 8 to rebound so that the fixing block 302 is inserted into the insertion slot, and complete the installation of the protection component.

[0037] When cable 1 twists due to friction, it will be blocked by the anti-deviation plate 202 on the fixed half ring 201, preventing cable 1 from twisting itself.

[0038] During disassembly, lift the pull plate 7 again to disengage the fixing block 302 from the insertion slot, then open the two fixing half rings 201 and remove the fixing half rings 201 from the cable 1.

[0039] This setup allows the protective components to be quickly installed on cable 1, preventing cable 1 from twisting automatically. Furthermore, its installation and removal are very convenient and will not significantly affect the speed of electrical construction.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
