Abstract

The invention relates to fire-fighting equipment, in particular to a fire extinguishing system for a stay cable tower end. The system comprises a spraying fire extinguisher and a controller, wherein the spraying fire extinguisher comprises a water tank fixed inside a cable tower; a water outlet pipe is arranged at the bottom of the water tank; the inlet end of the water outlet pipe communicates with the water tank; a water outlet main is arranged at the outlet end of the water inlet pipe; a plurality of branch pipes communicating with the water outlet main are arranged at the outlet end of the water outlet main; a plurality of nozzles directly facing stay cables and cable tower anchorage points are arranged on the branch pipes; the controller comprises a ball valve mounted on the water outlet main and a control cabinet used for controlling the opening-closing of the ball valve; and the ball valve is electrically connected with the control cabinet. According to the system provided by the invention, the comprehensive and detailed fire-fighting design is adopted for an anchorage area of the stay cable tower end, so that a fire disaster can be effectively prevented from occurring in course of both bridge construction and post-stage operation. By utilization of the control cabinet, a smoke signal is acquired, a spraying instruction is issued, fire is automatically and timely extinguished, and the fire disaster is prevented from spreading and endangering the bridge safety.

Description

technical field [0001] The invention relates to fire-fighting facilities, in particular to a fire-extinguishing system at the end of a cable-stayed cable tower. Background technique [0002] The cable-stayed bridge is a very common bridge structure in modern bridges and has many advantages. The upper ends of the stay cables of the cable-stayed bridge are usually anchored on the tower, and a fixed structure is arranged inside the tower to fix the stay cables, so that the weight of the bridge can be stably transferred to the tower. Generally speaking, considering that the interior of the cable tower and the stay cables are non-combustible materials, no fire protection facilities are installed in the current cable-stayed bridge structures. But in fact, fires may still occur on the tower. For example, on October 29, 2014, a fire accident occurred on the Chenzhou Bridge in Hunan. The cause of the accident was that the construction personnel inside the cable tower caused the acc...
