Description

Technical Field

[0001] The utility model relates to the field of sprinkler heads, in particular to an adaptive concealed intelligent sprinkler head. Background Art

[0002] Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the splash plate of the sprinkler head to extinguish the fire. They are divided into drooping sprinkler heads, upright sprinkler heads, ordinary sprinkler heads, side wall sprinkler heads, etc. Under the action of heat, they will start automatically within a predetermined temperature range, or be started by a control device according to a fire signal, and spray water according to the designed sprinkler shape and flow rate. Therefore, many large factories, workshops, halls, theaters and other buildings are equipped with fire sprinklers.

[0003] Concealed sprinkler heads usually refer to embedded fire sprinkler heads. They have beautiful structures and can prevent accidental touches. Therefore, they are widely used in shopping malls, office buildings and some factories. However, during use, concealed sprinkler heads are embedded in the wall, and the temperature conduction is delayed to a certain extent, resulting in the sprinkler heads not being sensitive enough to open. Often, the sprinkler heads will sense the external temperature and start spraying water to extinguish the fire only after the fire reaches a certain level. The use effect is poor, affecting the fire extinguishing efficiency. Therefore, it is urgent to develop an adaptive concealed intelligent sprinkler head that can hide and protect the sprinkler head from damage, and at the same time better sense the external ambient temperature to ensure the sprinkler head opening sensitivity. Utility Model Content

[0004] In order to overcome the disadvantage that concealed sprinkler heads are not sensitive enough to open, and the sprinkler heads often sense the external temperature and start spraying water to extinguish the fire only after the fire reaches a certain degree, resulting in poor use effect, the technical problem to be solved by the utility model is to provide an adaptive concealed intelligent sprinkler head that can hide and protect the sprinkler head from damage, and at the same time better sense the external ambient temperature to ensure the sprinkler head opening sensitivity.

[0020] Working principle:

[0021] The sprinkler head connection shaft 1 of the utility model is connected to the pressurized water network pipe through the pipe thread, and the sprinkler head is installed in the ceiling wall, which improves the aesthetics and can effectively prevent the sprinkler head from colliding with external objects, causing the thermal glass ball to break and spray by mistake; at the same time, the splash plate 8 of the sprinkler head of the utility model is arranged above the thermal glass column 7, and the thermal glass column 7 is arranged below the splash plate 8, located at the lower end opening of the protective cover 10, so that the thermal glass ball can better sense the temperature of the external environment, thereby ensuring the sensitivity of the sprinkler head to be opened.

[0022] When a fire occurs, the temperature above the fire source rises accordingly. When the temperature in the air reaches a certain height, it is quickly transmitted to the thermosensitive glass column 7. The liquid inside the thermosensitive glass column 7 begins to expand under the action of high temperature. When it expands to a certain extent, the liquid will squeeze the glass column. When the thermosensitive glass column 7 breaks, the top block 6 and the sealing block 5 lose their support. Under the impact of the water flow, the sealing block 5 and the top block 6 fall downward, and the splash plate 8 slidably mounted on the sliding frame 3 and fixedly connected to the top block 6 slides downward. The splash plate 8 slides down. To the lower end of the sliding frame 3; when the splash plate 8 slides downward, the inner surface of the slide groove of the splash plate 8 no longer abuts against the block 91, and the push block 92 pushes the block 91 outward under the action of the spring 93, so that the end of the block 91 that is stuck in the mounting hole of the fixed frame 2 is disengaged from the mounting hole, and the fixed frame 2 and the sliding frame 3 are no longer engaged, and then the sliding frame 3 slides downward along the fixed frame 2, so that the splash plate 8 extends out of the protective cover 10, and then the water flow hits the splash plate 8, and the splash plate 8 evenly sprays the water flow onto the fire source below to extinguish the fire.

[0023] Although the present disclosure has been described in detail with reference to the exemplary embodiments, the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the present disclosure.
