Embodiment approach 1

[0024] see figure 1 , 2 , 5. The first embodiment of the present invention provides a foldable pipe network type fire-fighting water mist fire extinguishing system, including a fire alarm controller 9, a fire detector 10, a valve group 7, a pump group 8, a foldable pipe network. The fire detector is connected with a fire alarm controller, the fire alarm device is connected with a valve group, the valve group is connected with a pump group, and the valve group is connected with a foldable pipe network. The fire extinguishing pipe network includes a branch pipe locking device 3 and several branch pipes 2; one end of the branch pipe 2 is connected with the main pipe 1 through a flexible joint 4, and the pipe body of the branch pipe 2 is provided with several nozzles 6; under normal conditions, The branch pipe locking device 3 locks the branch pipe 2, and fixes the branch pipe 2 horizontally or approximately horizontally; The other end rotates on the spot to make the branch pip...

Embodiment approach 2

[0030] The improvement of the first embodiment, the difference is that in the second embodiment, see image 3 , increasing the branch pipe limit device 5; the branch pipe limit device 5 is used to reduce the deformation of the branch pipe caused by the reaction force of the spray, so that when the branch pipe sprays, each nozzle on the pipe is equidistant from the protected object.

[0031] In this embodiment, the branch pipe limiting device 5 can be an elastic member plus a positioning baffle, the elastic member can be a spring, or other devices that can generate tension on the branch pipe 2, the purpose is to limit when the branch pipe is sprayed. deformation.

Embodiment approach 3

[0033] The third embodiment is an improvement on the second embodiment, the difference is that, in the third embodiment, the branch pipe limiting device has a damping deceleration function, see Figure 4 .

[0034] If there is no restriction when the branch pipe falls, the free end will vibrate repeatedly and affect the stability of the system. The branch pipe limit device can be a guide rail with a large friction force. When the branch pipe falls, the friction force slows down the falling speed. Grooves can be provided for fixing branch pipes.

Abstract

The invention provides a foldable pipe network type fire-fighting fine water mist fire extinguishing system, comprising a fire alarm controller, a fire detector, a valve group, a pump group, and a foldable pipe network. The fire detector is connected with a fire alarm controller, the fire alarm device is connected with a valve group, the valve group is connected with a pump group, and the valve group is connected with a foldable pipe network. The foldable pipe network includes a main pipe, a branch pipe, a flexible joint, a branch pipe locking device, and a branch pipe limit device. One end of the branch pipe is connected to the main pipe through a flexible joint, and the body of the branch pipe is provided with several nozzles; Under normal conditions, the branch pipe locking device fixes the branch pipe on one of the six surfaces where the protected object is located; under working conditions, the fire detector sends the fire alarm signal to the fire alarm controller, and the fire alarm controller sends a linkage signal For the valve group, after the valve group is started, the pump group is linked to start to supply water to the fine water mist pipe; the branch pipe lock device is opened, and under the action of external force, the branch pipe is bent to a position that is vertical or nearly perpendicular to one of the surfaces, and the branch pipe The final position of the run is determined by the branch pipe limit device.

Description

technical field [0001] The invention belongs to the field of fire protection, and in particular relates to a foldable pipe network type fire-fighting fine water mist fire extinguishing system. Background technique [0002] Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. At present, the more common fire extinguishing method is to install a water sprinkler system indoors or outdoors, such as figure 1 As shown, the main pipe and branch pipes of the fire extinguishing system are fixed on the bracket, and the nozzles of the branch pipe network are set near the ceiling. Spray fire. This method can meet the general fire protection needs. [0003] However, in warehouses or other similar special occasions, the volume of protected objects is large and it is not allowed to arrange fire extinguishing pipe networks around due to access requirements. The fixed fire extinguishing system can only...
