[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Please refer to Figure 1-2 , the present utility model provides a technical solution: a high-voltage cable fireproof bandage, which includes a base cloth layer 2 and an adhesive layer 1 provided on the base cloth layer 2. An insulating layer 3 is bonded to the side of the base cloth layer 2 away from the adhesive layer 1. A first fireproof layer 4 is bonded to the side of the insulating layer 3 away from the base cloth layer 2. An expansion layer 5 is bonded to the side of the first fireproof layer 4 away from the insulating layer 3. A buffer layer 6 is bonded to the side of the expansion layer 5 away from the first fireproof layer 4. A second fireproof layer 7 is bonded to the side of the buffer layer 6 away from the expansion layer 5. A waterproof layer 8 is bonded to the side of the second fireproof layer 7 away from the buffer layer 6. A wear-resistant layer 9 is bonded to the side of the waterproof layer 8 away from the second fireproof layer 7. A plurality of water guiding blocks 11 are provided on the wear-resistant layer 9, and a plurality of first buffer holes 10 are formed in the buffer layer 6.

[0019] Specifically, the base cloth layer 2 is woven from nylon fibers to ensure the strength of the bandage, and the adhesive layer 1 is made of an organosilicon binder to ensure the bonding effect of the bandage.

[0020] Specifically, the insulating layer 3 is made of PET material to improve the insulation of the bandage. The first fireproof layer 4 and the second fireproof layer 7 are bonded by glass fibers to ensure the fireproof effect of the bandage. The waterproof layer 8 is made of polyethylene material to prevent rainwater from entering the bandage and then into the cable.

[0021] Specifically, the expansion layer 5 is made of expanded perlite material. When the expansion layer 5 is heated, it will collide. At this time, the fireproof bandage is still tightly bonded to the cable, so that the fireproof bandage is more tightly bonded to the cable, preventing the flame from eroding the cable through the bonding gap. The buffer layer 6 is made of elastic foam material. The cross-section of the first buffer hole 10 is oval, and the first buffer hole 10 penetrates the width direction of the buffer layer 6 and is evenly provided with a plurality along the length direction of the buffer layer 6. When the bandage collides with the cable during shaking, through the elastic action of the buffer layer 6 and the deformation of the first buffer hole 10, the impact force is buffered, thereby reducing the loss of the fireproof bandage.

[0022] Specifically, the wear-resistant layer 9 is made of polycarbonate material to ensure the wear resistance of the surface of the fireproof bandage. The cross-section of the water guiding block 11 is conical and the side away from the wear-resistant layer 9 is the tip. A plurality of water guiding blocks 11 are arranged in a rectangular array on the surface of the wear-resistant layer 9. The water falling on the fireproof bandage can quickly drip through the tip of the surface of the water guiding block 11, thereby reducing the accumulation amount of rainwater on the fireproof bandage and improving the waterproof effect. A second buffer hole 12 is formed through the water guiding block 11. When the fireproof bandage collides, the deformation of the second buffer hole 12 can also buffer the impact force, thereby reducing the loss of the fireproof bandage. The water guiding block 11 is made of polycarbonate material to ensure the wear resistance of the water guiding block 11.

[0023] Specifically, fireproof coatings are applied on the surfaces of the base fabric layer 2, the insulating layer 3, the first fireproof layer 4, the expansion layer 5, the buffer layer 6, the second fireproof layer 7, the waterproof layer 8, the wear-resistant layer 9 and the water guiding blocks 11. The fireproof coatings can be made of chlorinated rubber, paraffin wax and various fireproof additives to improve the fireproof performance of the fireproof bandage.

[0024] A specific application example of this embodiment is as follows:

[0025] When the device is in use, when the bandage collides with the cable due to the shaking of the cable, through the elastic action of the buffer layer 6 and the deformation of the first buffer holes 10, the impact force is buffered. The deformation of the second buffer holes 12 can also buffer the impact force, thereby reducing the loss suffered by the fireproof bandage. Through the settings of the first fireproof layer 4, the second fireproof layer 7 and the fireproof coating, the fireproof performance of the fireproof bandage is improved. Through the setting of the insulating layer 3, the insulation of the fireproof bandage is improved. Through the setting of the expansion layer 5, the expansion layer 5 will collide after being heated. At this time, the fireproof bandage still adheres tightly to the cable, so that the adhesion of the fireproof bandage to the cable is closer, avoiding the flame from eroding the cable through the adhesion gap. Through the settings of the waterproof layer 8 and the water guiding blocks 11, the waterproof layer 8 improves the waterproof performance of the bandage, and the water falling on the fireproof bandage can quickly drip through the surface of the water guiding blocks 11, thereby reducing the accumulation amount of rainwater on the fireproof bandage and improving the waterproof effect.
