Description

Technical Field

[0001] The utility model belongs to the technical field of live working, and in particular relates to an insulation shielding device. Background Art

[0002] Insulating shielding cloth is a protective material designed specifically for electrical work, protecting workers from electric shock hazards while ensuring the safe operation of cables and energized equipment. Made from a highly insulating synthetic material, this cloth offers excellent electrical insulation and mechanical strength, effectively isolating live parts from the surrounding environment, preventing current leakage and short circuits.

[0003] When using insulating shielding cloth, it must first be evenly placed over the cable to be protected, ensuring electrical isolation between the cable and the external environment, thereby avoiding potential safety hazards. Subsequently, to maintain the stability and reliability of the shielding cloth, it must be firmly secured to the cable using specialized clips. These clips are typically made of metal and feature a well-designed design and moderate clamping force, ensuring that the shielding cloth will not fall off due to wind, contact, or other factors during operation.

[0004] However, although there are certain problems in the use of insulating masking cloth: the step of clamping it with clips is relatively cumbersome and time-consuming, which increases the difficulty and complexity of the operation. Utility Model Content

[0005] In view of this, the utility model provides an insulation shielding device, which can facilitate the use of the insulation shielding device, reduce the working time of construction workers, and improve construction efficiency.

[0006] The utility model is achieved in this way:

[0007] The utility model provides an insulating shielding device, which includes an insulating shielding cloth, wherein an internal clip and an external clip are fixedly connected on both sides of the insulating shielding cloth, the internal clip and the external clip are both "J"-shaped, the long sides of the internal clip and the external clip are fixedly connected to the insulating shielding cloth, and the arc-shaped parts of the internal clip and the external clip are used to hang on the cable line.

[0008] On the basis of the above technical solution, an insulation shielding device of the present invention can also be improved as follows:

[0009] Among them, the internal clip includes a first side clip, a first arc-shaped piece, and a second side clip. The cross-sections of the first side clip and the second side clip are both straight lines. The cross-section of the first arc-shaped piece is arc-shaped. The curvature of the first arc-shaped piece is greater than π. The inner wall is in contact with the cable. The opening of the first arc-shaped piece is fixedly connected to one side of the first side clip and the second side clip respectively, and one end of the first side clip is fixedly connected to the insulating shielding cloth.

[0010] Furthermore, the first side clip and the second side clip are parallel to each other, and a distance between the first side clip and the second side clip is greater than a diameter of the cable.

[0011] Furthermore, the inner wall of the first arc-shaped member is provided with rubber at the contact portion with the cable.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: rubber is an excellent electrical insulating material, which can effectively prevent the leakage of current and reduce the electrochemical corrosion between the cable and the clamp, thereby improving the safety and reliability of the entire shielding device; the rubber material has high elasticity and flexibility, which can provide additional mechanical protection for the cable, and reduce damage to the cable caused by external factors such as friction and impact; the rubber has good wear resistance, and can form a protective layer at the contact point between the cable and the clamp, reducing wear and extending the service life of the cable and the shielding device; rubber has a certain shock-absorbing effect, which can reduce the vibration of the cable when it is under force, reduce noise, and provide a quieter working environment for operators; the rubber surface friction coefficient is high, which can provide better grip, prevent the cable from sliding in the clamp, and ensure the stability of the shielding device during use; rubber materials generally have good chemical corrosion resistance, can maintain stable performance under various environmental conditions, and are suitable for different working environments.

[0013] Furthermore, the external clip includes a third side clip, a second arc-shaped piece and a fourth side clip. The third side clip is rectangular, one side of which is fixedly connected to the insulating shielding cloth, and the other side is fixedly connected to one side of the second arc-shaped piece. The cross-section of the second arc-shaped piece is an arc, and one end of the opening is fixedly connected to the fourth side clip. The fourth side clip is rectangular.

[0014] Furthermore, the third side clip and the fourth side clip are in contact with each other at one end away from the second arc-shaped member.

[0015] Furthermore, an axial protrusion is provided on an outer side of the fourth side clip at one end away from the second arc-shaped member.

[0016] Furthermore, both ends of the inner clip and the outer clip are provided with plug-in grooves, which are radial grooves located on the outside of one end of the inner clip and the outer clip and radial protrusions located on the inside of the other end, and the shapes of the radial grooves and the radial protrusions are adapted to each other.

[0017] Furthermore, the inner diameter of the second arc-shaped member is greater than the outer diameter of the first arc-shaped member.

[0018] Furthermore, the widths of the inner clip and the outer clip are equal to the width of the insulating shielding cloth.

[0019] Compared with the prior art, the beneficial effects of the insulation shielding device provided by the utility model are:

[0020] By setting internal and external clamps, it is convenient for workers to construct, reduce the use of insulation clamps, shorten the working time and improve the working efficiency;

[0021] The "J"-shaped design of the inner and outer clips provides a stable support structure, allowing the insulation shielding cloth to be securely hung on the cable line. This design reduces displacement or shedding caused by external factors such as wind and gravity, and improves the stability and reliability of the shielding device.

[0022] The first and second side clamps are parallel to each other and the distance between them can be greater than the diameter of the cable, allowing the device to adapt to cables of different diameters and increasing its flexibility. This design also allows construction workers to quickly adjust the clamp position according to the actual diameter of the cable, improving construction efficiency.

[0023] The inner wall of the first arc-shaped member is provided with rubber at the contact point with the cable. The excellent electrical insulation properties of rubber are utilized to effectively prevent current leakage, reduce electrochemical corrosion between the cable and the clamp, and enhance the safety and reliability of the entire shielding device.

[0024] The high elasticity and flexibility of rubber provide additional mechanical protection for cables, reducing damage to cables caused by external factors such as friction and impact. The wear resistance of rubber helps to extend the service life of cables and shielding devices;

[0025] Both ends of the inner and outer clips are provided with plug-in slots to facilitate the connection of multiple shielding devices, which not only makes the connection easier but also reduces the exposure of the insulating shielding cloth. BRIEF DESCRIPTION OF THE DRAWINGS
