Description
Technical Field
The invention belongs to the field of fire fighting, and particularly relates to a fire fighting pipe network.
Background
Among the various disasters, fire is one of the main disasters that threaten public safety and social development most often and most generally. At present, a fire extinguishing mode is that a fixed fire extinguishing pipe network is installed indoors or outdoors, as shown in fig. 1, a main pipeline and a branch pipeline of a fire extinguishing system are fixed on an immovable support, a nozzle of the branch pipe network is arranged near a ceiling, and when an induction element of the nozzle is heated and burst or a fire automatic alarm system detects fire and then a linkage deluge valve is started, the nozzle sprays water to extinguish the fire. The mode can meet the general fire-fighting requirement.
However, in warehouses or other similar special situations, the protected objects are bulky and do not allow the deployment of fire-fighting networks due to the access requirements. The fixed fire extinguishing system can only be arranged on a ceiling, if a fire disaster happens on the lower layer of a protected object, water sprayed by a spray head of the ceiling is difficult to be sprayed to a fire point, and the fire extinguishing efficiency is seriously influenced. Some water sprinkler systems, while also located along a side of the protected object, are still far less effective at extinguishing fires than water spray or mist fire suppression systems.
Disclosure of Invention
In order to solve the problem that the existing fire-fighting pipe network can only spray water to the top or the local side of a goods shelf and has low fire-fighting efficiency for low-rise protected objects, the non-fixed fire-fighting pipe network is provided. The following scheme is adopted specifically:
comprises a main pipeline, branch pipelines, flexible joints, branch pipeline locking devices and branch pipeline limiting devices. One end of the branch pipeline is connected with the main pipeline through a flexible joint, and a plurality of nozzles are arranged on the pipe body of the branch pipeline. Under a normal state, the branch pipeline locking device fixes the branch pipeline on one surface of six-surface space where the protected object is located; under the working state, the branch pipeline locking device is opened, under the action of external force, the branch pipeline radially rotates to a position vertical to or close to one surface of the branch pipeline by taking the flexible joint as an axis, and the final running position of the branch pipeline is determined by the branch pipeline limiting device.
Furthermore, one of the surfaces is an upper top surface, and the branch pipeline is fixed at a horizontal position or a position close to the horizontal position by the branch pipeline locking device in a normal state; under the action of gravity, the branch pipeline rotates to a vertical position or a position close to the vertical position in a radial direction by taking the flexible joint as an axis.
Further, the flexible joint is a pressure rotary joint.
Furthermore, the branch pipeline limiting device is used for final positioning of the operation of the branch pipeline and reducing the deformation of the branch pipeline caused by the reaction force generated by the fire extinguishing agent sprayed by the branch pipeline.
Furthermore, the branch pipeline limiting device is a spring mechanism.
Furthermore, the branch pipeline limiting device is a damping delay mechanism.
Further, the locking device is an electric control clamping device.
Further, the locking device is a hydraulic driving clamping device.
Further, the locking device is a mechanical driving clamping device.
Further, the fire extinguishing agent is water mist.
In this application, through spraying water with present downwards or local side and change into downwards and whole side and spout fire extinguishing agent for when the conflagration breaing out in goods shelves arbitrary part, fire extinguishing agent can both be sprayed closely and put the ignition, promotes the efficiency of putting out a fire.
When no fire occurs, the branch pipelines can be arranged on a horizontal plane parallel to the main pipeline and are buckled by the branch pipeline locking device. When a fire disaster happens, the locking device loosens the branch pipeline after receiving the unlocking signal. The branch pipeline starts to rotate in a fan shape along the rotating direction of the rotating joint under the action of gravity or other power, the fan-shaped motion track is vertical to the ground or parallel to the ground, and the branch pipeline finally falls into the branch pipeline limiting device and is positioned. In the process, the fire extinguishing pipe network can start to spray the fire extinguishing agent at any time from the beginning to the end of the movement.
The branch pipeline limiting device is used for final positioning of the operation of the branch pipeline and reducing deformation caused by reaction force generated by the fire extinguishing agent sprayed by the branch pipeline.
When water, water spray or water mist is ejected, a reaction force is generated on the branch pipe network on the axis of the nozzle. Because one end of the branch pipeline is fixed on the flexible joint and the other end is not fixed, the reaction force can lead the branch pipeline to generate deformation far away from the protected object, thereby leading the spraying of the fire extinguishing agent to be uneven due to different distances between the spray head and the protected object. Therefore, in the application, by designing the branch pipeline limiting device, the device exerts an acting force on the branch pipeline to offset the counterforce generated when the fire extinguishing agent is sprayed, so that the branch pipeline is fixed when being sprayed, and the distance between each spray head on the branch pipeline and the protected object is kept uniform.
