Problems solved by technology

[0004] With the setting of the water retaining plate in the existing fire sprinkler, although the radiation range of the water column has been expanded, due to the spraying of water, the water volume directly below is relatively less distributed, resulting in poor fire control there. In the early stage of a fire, it is difficult for people to detect it. When it is detected, the fire often spreads in a large area, which makes it difficult to evacuate the surrounding people and poses a large safety hazard.

Embodiment 1

[0045] see figure 1 , a sinking type double-layer fire sprinkler head, comprising a top plate 1, the upper end of the top plate 1 is connected with a threaded end 2, and the threaded end 2 is provided with an upper water retaining plate 5, and the upper water retaining plate 5 is connected with a base, the base Two connecting columns 3 are connected between the outer end and the top plate 1 , glass columns 4 are connected between the upper end of the base and the lower end of the top plate 1 , and a plurality of evenly distributed water distribution grooves 6 are excavated on the edge of the upper water retaining plate 5 .

[0046] see Figure 2-3 , the upper water retaining plate 5 is excavated with a plurality of evenly distributed inner sink holes, the inner sink hole is provided with a sinking plate, and the sinking plate includes a lower water retaining plate 7, between the lower water retaining plate 7 and the inner wall of the inner sink hole The rubber sealing ring 8 ...

Embodiment 2

[0049] see Figure 6-7 , the outer end of the lower water retaining plate 7 of the sinking plate is fixedly connected with a sinking chain 10, and the edge of the sinking chain 10 away from the lower water retaining plate 7 is fixedly connected with the inner wall of the inner sinking hole, please refer to Figure 8 , through the sinking chain 10, the lower water retaining plate 7 presents a basin shape after sinking, which has a certain water gathering effect, and cooperates with it to connect the base and the upper water retaining plate 5 through an electric rotating shaft, so that it can be used when spraying water. , can be in a rotating state, and then make the water in the lower water retaining tray 7 splash outwards quickly under the action of centrifugal force, and then significantly expand its spray range, so that the fire control effect is better.

[0050] A glue seal layer 81 is poured in the inner sink hole, and the glue seal layer 81 is also made of water-soluble ...

Abstract

The invention discloses a sunken double-layer fire sprinkler, and belongs to the field of fire sprinklers. According to the sunken double-layer fire sprinkler, through the arrangement of a lower water retaining disc, when water overflows, the lower water retaining disc sinks, then two water retaining layers are formed under the sprinkler, on one hand, part of water can directly fall down conveniently; compared with the prior art, the water quantity under the sprinkler is obviously increased, the fire control effect is better, on the other hand, due to a double-layer water retaining effect, the water quantity is effectively dispersed, the radiation range of a water column is expanded, the fire fighting effect is improved, in addition, in cooperation with the arrangement of a sound alarm early warning ball, when a fire occurs, under the action of the high temperature of a thermal explosion ball, the thermal explosion ball is rapidly expanded and exploded. Therefore, harsh blasting sound is made, surrounding people are reminded in time, the situation that the people are trapped is effectively avoided, and then potential safety hazards are remarkably reduced.

Description

technical field [0001] The invention relates to the field of fire sprinklers, in particular to a sunken double-layer fire sprinkler. Background technique [0002] The fire sprinkler is used in the fire sprinkler system. When a fire occurs, the water is sprayed out through the sprinkler splash plate to extinguish the fire. It is divided into a pendant sprinkler, a vertical sprinkler, a common sprinkler, a side wall sprinkler, etc. . [0003] The pendant sprinkler is the most widely used sprinkler. It is installed droopingly on the water supply branch pipe. The shape of the sprinkling is parabolic, and 80-100% of the total water is sprayed to the ground. To protect rooms with suspended ceilings, sprinkler heads should be arranged under the suspended ceiling, and drooping sprinklers or ceiling-mounted sprinklers should be used. [0004] With the setting of the water retaining plate in the existing fire sprinkler, although the radiation range of the water column has been expan...
