Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in figure 1, the utility model discloses a metal mesh plate 2 for holding fire and examining optic fibre 1, two rows of spacing rollers 3 around being equipped with at metal mesh plate 2's upper surface, fire is examined optic fibre 1 and is located around two rows between the spacing roller 3, and two rows of spacing rollers 3 can examine optic fibre 1 to the fire and play limiting displacement around, avoid the fire to examine optic fibre 1 and drop from metal mesh plate 2. And the fire detection optical fiber fixing mechanism is arranged along the arrangement direction of the limiting rollers 3. The fire detection optical fiber fixing mechanism comprises a micro portal frame 4 fixedly connected with the upper surface of the metal mesh plate 2, a screw rod 6 is in threaded connection with an upper beam of the micro portal frame 4, the lower end of the screw rod 6 is fixedly connected with a pressing disc 5 used for pressing the fire detection optical fiber 1, and the upper end of the screw rod 6 is fixedly connected with a handle 7.
The metal mesh plate 2 is connected with a chassis 11 provided with walking wheels through supporting legs 10, a supporting plate 9 is arranged between the metal mesh plate 2 and the chassis 11, a cooling fan 12 is arranged on the supporting plate 9, and the air supply direction of the cooling fan 12 faces to the metal mesh plate 2.
