Description

Technical Field

[0001] The present invention relates to the technical field of cables, and particularly to an anti-interference cable for multi-power split transmission. Background Art

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Anti-interference means setting a shielding layer made of the same material as the conductor on the outer side of the insulator to absorb the influence of the electromagnetic field. Multi-power split transmission means transmitting power under different frequency conditions.

[0003] According to the search, a Chinese patent with the patent number CN114496377A discloses a cable and a cable assembly, including a wrapping layer, a cable line arranged in the wrapping layer, two aggregate sleeves arranged outside the wrapping layer, and a fixing plate located outside the wrapping layer between the two aggregate sleeves. The fixing frame is an L-shaped bent frame that extends away from the rear side of the wrapping layer and then bends downward, and a fixing groove is opened at the downward bending end of the fixing frame; the fixing plate is a circular plate, and an annular sliding rail is opened on its end face. When lightning strikes the cable and causes the fire to spread along the cable and is about to enter the house, it forces the sprinkling holes at the bottom of the functional seat to melt. When a fire occurs, this assembly can also swing above the cable line, so that the fire extinguishing medium is evenly sprinkled on the fire source to extinguish the fire, achieving the purpose of fire prevention and extinguishing and reducing the loss of people's property.

[0004] Aiming at the deficiencies of the above device, in the above device, the fusible plug is blocked by the heat of the high-temperature fire of the cable, causing it to melt, forcing the sprinkling holes to open and the fire extinguishing medium to be sprinkled on the aggregate sleeve. If it encounters a high-temperature environment, the fusible plug can also melt, resulting in waste of the medium being spilled; the functional seat swings back and forth above the aggregate sleeve to make the spilled fire extinguishing medium evenly sprayed. The cable needs to be extinguished in a short time when it burns. By swinging the functional seat to spray the medium to extinguish the fire, the fire extinguishing effect is relatively poor, and the swinging spray needs to be uniform enough to cover the fire range; the above device is fixed on the cable, and for different specifications of cables, it needs to be redesigned and installed, with cumbersome operations.

[0005] Aiming at the above problems, the present invention provides an anti-interference cable for multi-power split transmission. Summary of the Invention

The sleeve 15 rotates around the cable 1, thereby driving the air injection holes 18 to rotate around the cable 1 and spray carbon dioxide for fire extinguishing. The purpose of this design is to detect the situation of the in-house cable 1 in real time through the smoke sensor 42. If a fire is detected, it is timely fed back to the device for fire extinguishing; the adjustable arc-shaped pressing plate 10 on the circular ring body 2 centers and clamps different specifications of cables 1, which not only plays a role in fixing the fixing device, but also provides positioning for the subsequent device to spray gas while rotating for fire extinguishing; the rotation of the cam column 30 not only realizes the repeated supply of fire extinguishing gas into the sleeve 15, but also drives the sleeve 15 to rotate, realizing spraying gas while rotating, so that the fire is relatively effectively controlled.

[0044] In summary, when installing the device for different cables 1, the end of the incoming cable 1 passes through the middle of the sleeve 15 on one side, passes through the middle of the fixing sleeve 3, and passes out through the middle of the sleeve 15 on the other side. By using a tool to rotate the external thread ring body 4 within the gap on the side of the sleeve 15, the external thread ring body 4 rotates on the arc-shaped frame 11. The external thread ring body 4 rotates and moves along the axis direction of the fixing sleeve 3. The rotation of the external thread ring body 4 drives the first cylinder 8 to move radially along the circular ring body 2, and drives the arc-shaped pressing plate 10 on the U-shaped frame 9 to move radially inward along the circular ring body 2 through the rectangular block 7, clamping different cables 1. Then, the second box body 40 is fixedly installed on the wall through bolts. When lightning strikes cause the cable 1 to catch fire and the fire spreads along the cable 1 into the room, the smoke sensor 42 detects the smoke concentration and feeds back the signal to the data processing module. After processing, the data processing module feeds back the signal to the control module. The control module controls the motor 31 to start. The rotation of the motor 31 drives the cam column 30 to rotate, thereby driving the first telescopic rod 21 and the second telescopic rod 34 to reciprocate vertically. The movement of the first telescopic rod 21 drives the second cylinder 29 on the two side sliders 27 to move away from or towards each other horizontally, driving the two sleeves 15 to rotate synchronously in the positive or negative direction. At the same time, the movement of the second telescopic rod 34 drives the lifting plate 36 to reciprocate vertically. The carbon dioxide in the second box body 40 is pumped into the first box body 33 through the first telescopic hose 38, and then the carbon dioxide in the first box body 33 is pumped into the ventilation pipe 17 through the second telescopic hose 39, and then sprayed out through the air spray holes 18 to extinguish the fire on the cable 1. The sleeve 15 rotates around the cable 1, thereby driving the air spray holes 18 to rotate around the cable 1 and spray carbon dioxide for fire extinguishing. The purpose of this design is to detect the situation of the incoming cable 1 in real time through the smoke sensor 42. If a fire is detected, it is timely fed back to the device for fire extinguishing; the adjustable arc-shaped pressing plate 10 on the circular ring body 2 centers and clamps different specifications of cables 1, which not only plays a role in fixing the fixing device, but also provides positioning for the subsequent device to spray gas while rotating for fire extinguishing; the rotation of the cam column 30 not only realizes the repeated supply of fire extinguishing gas into the sleeve 15, but also drives the sleeve 15 to rotate, realizing spraying gas while rotating, so that the fire is relatively effectively controlled.
