Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to an automatic fire protection sprinkler device for buildings. Background Art

[0002] Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the sprinkler head splash plate to extinguish the fire:

[0003] In the existing building fire sprinkler device, when a fire occurs, the temperature of the organic solution rises and expands until the glass body breaks, the ball seat and the seal lose their support and are washed away by the water flow, thus starting to spray water to extinguish the fire;

[0004] There are some problems, for example, the transmission effect of the installation method is not good, glass fragments are likely to splash when a fire occurs, and the sprinkler mouth is prone to being blocked by dust when it is not used for a long time at the construction site. For this reason, we propose an automatic building fire sprinkler device. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a building fire automatic sprinkler device with good protection effect, effectively protecting the sprinkler port, and effectively solving the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic fire sprinkler device for a building, comprising an upper mounting column and a sprinkler blocking mechanism;

[0007] The upper mounting column: the lower side thereof is fixedly connected with evenly distributed telescopic rods, and the lower sides of the telescopic ends of the three telescopic rods are fixedly connected to the bottom inner wall of a bottom protective shell;

[0008] Spray blocking mechanism: It includes an upper inner spiral hole, a screw-on sleeve, an upper outer thread, an upper molten glass tube and a blocking round buckle. The upper inner spiral hole is opened in the middle of the lower surface of the upper mounting column. The upper end of the screw-on sleeve is provided with an upper outer thread. The interior of the upper inner spiral hole is threadedly connected to the upper outer thread. The inner ring of the screw-on sleeve is fixedly connected with evenly distributed upper molten glass tubes. The ends of the three screw-on sleeves facing the center of the upper mounting column are fixedly connected to the outer arc surface of a blocking round buckle. When there is no fire, the spray port is in the protective shell to prevent dust from blocking the spray port.

[0009] Furthermore, the spray blocking mechanism also includes a lower threaded hole, a lower screwing column, a lower external thread and a lower molten glass tube. The lower molten glass tube is fixedly connected to the lower surface of the blocking round buckle, and the lower end of the lower molten glass tube is fixedly connected to the lower screwing column. The outer arc surface of the lower screwing column is provided with a lower external thread, and the lower end of the bottom protective shell is provided with a lower threaded hole. The lower external thread is connected to the internal thread of the lower threaded hole to realize the bottom installation function.

[0010] Furthermore, it also includes springs, which are fixedly connected between the lower surface of the upper mounting column and the bottom inner wall of the bottom protective shell. The springs are movably mounted on the outer surfaces of the three telescopic rods to achieve the function of adjusting the position of the bottom protective shell.

[0011] Furthermore, it also includes a diverter plate, which is fixedly connected to the lower side of the outer arc surface of the bottom protective shell to achieve the function of water flow diversion.

[0012] Furthermore, it also includes a lower water outlet, which is evenly opened on the bottom surface of the bottom protective shell. The outer arc surface of the bottom protective shell is provided with evenly distributed air vents, and the inside of the four air vents are provided with protective nets to achieve the function of bottom water outlet.

[0013] Furthermore, it also includes a mounting plate, which is evenly fixedly connected to the upper surface of the upper mounting column, and the upper surfaces of the three mounting plates are all provided with mounting holes to achieve the installation function.

[0014] Furthermore, it also includes a water inlet pipe, which is arranged in the middle of the upper surface of the upper mounting column. A water guide hole is opened inside the upper mounting column. The lower side of the water guide hole is connected with the lower threaded hole. The lower end of the water inlet pipe is connected with the upper end of the water guide hole. The upper end of the water inlet pipe is connected to an external water supply device to realize the water supply function.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the building fire automatic sprinkler device has the following advantages:

[0016] 1. When you need to install this sprinkler device, manually pick up the lower screw-on column and screw it into the lower threaded hole. The hole pitch of the lower threaded hole is larger than the upper inner spiral hole. The screw-on sleeve can easily pass through the lower threaded hole. Then manually twist the lower screw-on column to screw the lower screw-on column into the lower threaded hole through the lower outer thread. At the same time, the screw-on sleeve is also screwed into the upper inner spiral hole through the upper outer thread. At this time, the sprinkler device can be used normally, and the transmission effect of the installation method is continuous during the building fire protection process.

[0017] 2. When a fire occurs at a construction site, high-temperature gases will be generated. These high-temperature gases will be transmitted to the interior of the bottom protective shell through the vent. At this time, the upper molten glass tube and the lower molten glass tube will break, and the generated glass fragments will fall into the interior of the bottom protective shell. At this time, high-pressure water will be sprayed out through the water guide hole, and the blocking round buckle will also fall into the interior of the bottom protective shell, avoiding the danger caused by the splashing of glass fragments.

[0018] 3. When spraying is needed, the water flow impacts the bottom protective shell. Under the influence of the elastic force of the spring, the three telescopic rods extend, and the high-pressure water flow flushes the bottom protective shell, and then passes through the diversion of the diverter plate to achieve spraying. When there is no fire in the building fire fighting process, the spray port is in the protective shell to prevent dust from clogging the spray port. BRIEF DESCRIPTION OF THE DRAWINGS
