[0022] The guide rail 2 is made of a flexible material, and the guide rail 2 is made of a rubber material, and can be used on a curved wall.

[0023] Embodiment 2: like Figure 7 , Figure 8 As shown, the front inner wall of the inspection cover 801 is fixedly connected with a telescopic rod 3 824 and a spring 2 825, the rear ends of the telescopic rod 3 824 and the spring 2 825 are fixedly connected with a mounting plate 826, the rear side of the mounting plate 826 is fixedly connected with a connecting rod 827, the rear end of the connecting rod 827 is fixedly connected with a clamping piece 828, the front side of the trigger plate 831 is provided with a friction slope 832, the rear side of the mounting plate 826 is provided with a moving groove 833, the inner side of the moving groove 833 is slidably connected with a moving block 835, the rear side of the moving block 835 is fixed A push rod 836 is connected, a spring three 834 is fixedly connected between the outer side of the moving block 835 and the inner wall of the moving groove 833, the rear side of the push rod 836 is slidably connected to the friction slope 832, the clamping piece 828 is an arc-shaped structure, the U-shaped airbag 813 is located on the outer side of the clamping piece 828 and the rear side extends to the front side of the arc plate 839, when the trigger plate 831 is used in conjunction with the mounting plate 826, the spring two 825 is in a compressed state, the clamping piece 828 is located between the card slots 806 on both sides, and the moving block 835 is an I-shaped structure. The moving block 835 is arranged inside the moving groove 833. The moving block 835 of the I-shaped structure prevents the push rod 836 from being separated from the moving groove 833. When the U-shaped airbag 813 expands, the U-shaped airbag 813 drives the trigger plate 831 to move forward, and the trigger plate 831 drives the friction slope 832 to move backward. The friction slope 832 squeezes the push rod 836 to move. When the push rod 836 moves to the rear end of the friction slope 832, the push rod 836 separates from the friction slope 832. Since the spring 825 is in a compressed state at this time, when the push rod 836 and the friction slope 832 are pressed, the push rod 836 and the friction slope 832 are pressed. When the slope 832 is separated, the friction force between the push rod 836 and the trigger plate 831 is smaller than the elastic force of the second spring 825, and the friction force between the friction slope 832 and the push rod 836 is greater than the elastic force of the second spring 825. Therefore, the elastic force of the second spring 825 drives the mounting plate 826 to move backward, and the mounting plate 826 drives the connecting rod 827 to move backward. The connecting rod 827 drives the clamping plate 828 to move backward, so that the clamping plate 828 clamps the burning wire, supports the wire, prevents the wire from burning and falling, and controls the fire.

[0024] Embodiment three: like Figure 7 , Figure 8 As shown, a trigger switch 837 is fixedly connected to the rear side of the mounting plate 826, a pressing block 838 is fixedly connected to the upper side of the trigger plate 831, and the clamping plate 828 is in contact with the wire. When the temperature of the wire continues to rise, the U-shaped airbag 813 continues to expand, and the trigger plate 831 drives the pressing block 838 to move forward and backward. When the pressing block 838 contacts the trigger switch 837 (the sealing plate 805 is closed at this time), the prompt light bar 10 and the alarm light 9 are started at the same time, so as to facilitate double alarm.

[0025] Working principle: When in use, the line monitor monitors the power line. When a fire occurs in the line, the motor 11 drives the conveying wheel 7 to rotate, so as to control the alarm body 1 to move to the fire position. As the line fire temperature rises, the U-shaped airbag 813 expands, and the U-shaped airbag 813 drives the abutment plate 817 to move. Under the action of the control rod 818, the trapezoidal block 819 is controlled to move forward. Under the action of the arc block 823, the horizontal rod 820, and the moving plate 815, the control blocks 810 on the left and right sides are controlled to move toward each other. Under the action of the connecting plate 808, the sealing plates 805 on the upper and lower sides are controlled to move closer to each other, so that the sealing plates 805 and the inspection cover 801 are connected. The arc-shaped plates 839 are combined to form a sealed cavity, which is convenient for isolating the external air and extinguishing the fire on the line, and providing sufficient time for the staff to carry out maintenance. At the same time, the U-shaped airbag 813 drives the trigger plate 831 to move forward, and the trigger plate 831 drives the friction slope 832 to move backward. When the friction slope 832 is separated from the support rod 836, under the action of the spring 2 825, the clamping plate 828 is controlled to clamp the line, so that the line is quickly extinguished, and the line is supported to prevent the line from burning and falling, causing accidents, thereby increasing safety. Under the action of the alarm light 9 and the prompt light bar 10, it is convenient for the staff to quickly locate the fire position and facilitate maintenance.
