Background

The fire-fighting sprinkler head is a sprinkler which is automatically started in a preset temperature range under the action of heat or is started by control equipment according to a fire signal and sprinkles water according to a designed sprinkling shape and flow, and the fire-fighting sprinkler head mostly disperses the sprayed water through a splashing disc so as to increase the sprinkling area, but the splashing disc has weak water flow dispersing capacity and limited sprinkling area, so that fire cannot be extinguished in time due to the reason in a big fire;

the spray nozzle in the prior art is additionally provided with the spiral baffle plate inside, so that when the spray water flows through the spray pipeline, the spiral baffle plate exerts a rotating effect on the water flow, the spray water sprayed out of the fire-extinguishing spray nozzle achieves a rotating effect, the spray water is rotationally sprayed out through the centrifugal force of the spray water, the spray area is increased, when a fire disaster occurs, flames can be effectively covered in a spraying mode, the fire spreading speed is reduced, but the sprayed water flow is dispersed through rotation to improve the spray area, so that the water flow sprayed out of the spray nozzle is dispersed, the water flow contacted with the flames in a unit area is reduced, when the fire disaster is large, the fire suppression capability of the liquid sprayed out of the spray nozzle on the fire disaster in the unit area is reduced, the time required by fire extinguishment is prolonged, the fire disaster is difficult to be rapidly controlled, and the individual volume of the spray nozzle is small, the flow of watering is limited, and when the great condition of intensity of a fire appeared, because the discharge of shower water is less, is difficult to produce the suppression effect to the intensity of a fire fast to make the conflagration further cause loss of property to personnel.

Disclosure of Invention

According to the technical problem, the utility model provides an wisdom is rotatory discharge type water spray shower for fire control which is characterized in that includes water pressure reinforcing mechanism, left spray tube, right spray tube, water service pipe, the left end of water service pipe bottom has left spray tube through the screw-thread meshing, the right end of water service pipe bottom has right spray tube through the screw-thread meshing, the water service pipe top is connected with external water pipe, the water service pipe inside wall has been seted up the chute, the chute number is two, this chute is provided with water pressure reinforcing mechanism;

the water pressure enhancing mechanism comprises a baffle, a baffle rotating shaft, an air vent pipeline, telescopic rods, telescopic rod rotating shafts and springs, wherein the inclined grooves formed in the inner side wall of the water service pipe are provided with air vent pipelines, the left side and the right side in the lower pipe wall of each air vent pipeline are respectively provided with a sliding groove, the two sliding grooves are respectively provided with a telescopic rod, one end of each spring is welded at the upper end of each telescopic rod, and the other end of each spring is welded inside the corresponding sliding groove of the air vent pipeline; the top ends of the two telescopic rods are respectively provided with a telescopic rod rotating shaft, and the other ends of the two telescopic rod rotating shafts are respectively connected with the baffle through bolts; the upper side of the baffle is provided with a baffle rotating shaft, the baffle is connected with an air duct through the baffle rotating shaft, and the air duct is connected with an external air pump when the name of the air duct is wrongly written.

The utility model has the advantages that:

the utility model achieves the purposes of supplementing the water spraying amount reduced by rotation and changing the water spraying coverage area by adding the water service pipe, the left spray pipe and the right spray pipe, thereby increasing the liquid flow of the spraying work under the combined action of the left spray pipe and the right spray pipe, supplementing the water spraying amount per unit area reduced by rotation, avoiding the water dispersion caused by rotation, avoiding the phenomenon that fire can not be put out intensively, and accelerating the speed of putting out big fire;

the utility model discloses an increase by the baffle, the baffle pivot, the air vent line, the telescopic link pivot, the water pressure reinforcing mechanism that the spring constitutes, the purpose of further increase discharge has been reached, make can push the baffle under its self atmospheric pressure respectively through the baffle pivot when high strength air current passes through the air vent line, the telescopic link pivot, the telescopic link and the effect of spring, thereby get into in the water service pipe, increase atmospheric pressure with the shower water of downward circulation in the water service pipe, thereby can be under the dual spraying effect of left spray tube and right spray tube, when further increasing the conflagration emergence, the shower water flow that is used for putting out a fire, and then increased the speed of putting out a fire by a wide margin, effectively avoided the conflagration further to cause the condition emergence of personnel loss of property; and because the telescopic link of being connected with the baffle is hindered by the spout, the baffle can't remove to breather pipe one side to can only pass through the gaseous promotion one-way to the water service pipe inside removal of high strength, when spraying work goes on, the baffle can produce certain effect of sheltering from to the breather pipe of slant under shed, thereby in the shower water of downward flow is difficult to see through the baffle and enters into the breather pipe, and then the effectual phenomenon of having avoided the shower water to get into the breather pipe and produce the backward flow takes place, has improved the practicality.
