[0038] Specifically, the high temperature causes the heat-sensitive glass tube 25 to break, and the valve plate 28 will fall off, and further the coolant inside the cooling tank 3 will be sprayed out from the nozzle 23 to extinguish the fire.

[0040] Preferably, the fan blades 26 in the nozzle 23 will rotate to drive the screw 10 to rotate, and the rotation of the screw 10 will drive the support plate 9 to move upward. The upward movement of the support plate 9 will drive the cables placed above the support plate 9 to move upward, so that the wires and the bridge body 1 are separated and not in contact, thereby reducing the heat conduction of the bridge body 1 in the event of a fire.

[0041] Please see attached Figure 1 -Attached Figure 8In a preferred embodiment, the cooling component includes: an air box 4, there are two air boxes 4, the two air boxes 4 are fixedly installed on the top of the cover plate 2, each air box 4 is connected to the top and installed with an air inlet pipe 5, each air inlet pipe 5 is installed with a first one-way valve, and the other end of each air inlet pipe 5 passes through the cover plate 2, and a hollow plate 21 is fixedly installed horizontally at the bottom of the cover plate 2, the two air boxes 4 are connected to the hollow plate 21 through a connecting pipe, and a plurality of evenly distributed air outlet pipes 22 are installed in a straight line at the bottom of the hollow plate 21, and each air outlet pipe 22 is installed with a second one-way valve, and each air box 4 is slidably installed inside. There is a piston plate 19, both ends of the top of the cover plate 2 are rotatably mounted with a turntable 8, the outer edge of the top of each turntable 8 is rotatably mounted with a movable plate 7, and the end of each movable plate 7 away from the turntable 8 is rotatably mounted with a connecting plate 6, and the end of each connecting plate 6 away from the movable plate 7 passes through the corresponding air box 4 and is fixedly mounted on the side of the piston plate 19, and both ends of the bottom of the cover plate 2 are vertically rotatably mounted with a turn rod 20, and the top of each turn rod 20 is fixedly mounted on the center of the bottom of the corresponding turntable 8 through a connecting shaft, and a spline groove is opened at the bottom of the turn rod 20, and a spline shaft is installed at the top of the screw 10, and the spline groove and the spline shaft are adapted;

[0042] Furthermore, the gas inside the air box 4 will be ejected from the air outlet pipe 22 through the hollow plate 21, which can not only cool the lifted cable by blowing, but also accelerate the air flow rate inside the bridge body 1, thereby improving the heat dissipation effect on the cable.

[0043] The working principle of the present invention is as follows: firstly, the bridge body 1 is installed at a designated position, and the cable is passed through the bridge body 1, and the cable is placed on the support plate 9, and then the cover plate 2 is clamped on the bridge body 1, and the spline shaft is inserted into the spline groove. It should be noted that when no fire occurs, the coolant in the cooling groove 3 will conduct heat and cool the cable;

[0044] When a fire occurs, the heat-sensitive glass tube 25 is broken due to the high temperature, and the valve plate 28 will fall off. Further, the coolant in the cooling tank 3 will be sprayed out from the nozzle 23 to extinguish the fire, and the fan blade 26 located inside the nozzle 23 will rotate. The rotation of the fan blade 26 drives the rotating rod 20 to rotate, and the rotation of the rotating rod 20 drives the screw 10 to rotate. The rotation of the screw 10 drives the support plate 9 to move upward, and the upward movement of the support plate 9 drives the cable to move upward, further making the cable and the bridge body 1 non-contact, avoiding the overheating of the cable caused by the heat conduction of the bridge. In addition, the support plate 9 The plate 9 moves upward and contacts the slope on the inclined plate 13 to move the inclined plate 13. The movement of the inclined plate 13 drives the baffle 12 to move, so that the baffle 12 can block the heat dissipation groove 11, thereby preventing the external fire from entering the bridge body 1. The rotation of the lead screw 10 also drives the spline shaft to rotate, and the rotation of the spline shaft drives the spline groove and the rotating rod 20 to rotate. The rotation of the rotating rod 20 drives the turntable 8 to rotate, and the rotation of the turntable 8 drives the movable plate 7 to move. The movement of the movable plate 7 drives the connecting plate 6 to reciprocate, and the movement of the connecting plate 6 drives the piston plate 19 to reciprocate. When the piston When the plate 19 moves toward the direction approaching the turntable 8, the first one-way valve on the air inlet pipe 5 opens, and the second one-way valve on the air outlet pipe 22 closes, then the external gas will enter the air box 4 through the air inlet pipe 5. When the piston plate 19 moves toward the direction away from the turntable 8, the first one-way valve on the air inlet pipe 5 closes, and the second one-way valve on the air outlet pipe 22 opens, and the gas inside the air box 4 will pass through the hollow plate 21 and be ejected from the air outlet pipe 22, which can not only blow and cool the lifted cable, but also speed up the airflow rate inside the bridge body 1. , to improve the heat dissipation effect of the cable. It should be noted that only a part of the screw 10 has external threads. After the support plate 9 moves upward a certain distance, the support plate 9 and the screw 10 will no longer be connected by threads. Furthermore, at this time, even if the screw 10 continues to rotate the support plate 9, it will not move upward anymore, ensuring that the airflow inside the bridge body 1 can flow all the time, and the support plate 9 will not drive the cable to move upward and contact the cover plate 2, so that the bridge body 1 and the cover plate 2 will not conduct heat to the cable in the event of a fire, thereby improving the use effect of the equipment.

[0045] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
