Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting ventilation, and in particular relates to a ventilation device for fire-fighting safety. Background Art

[0002] Fire ventilation is an important part of the fire protection system of a building. Smoke exhaust systems usually include natural smoke exhaust and mechanical smoke exhaust. Natural smoke exhaust uses the buoyancy of smoke or wind pressure difference to exhaust smoke through the smoke exhaust port; mechanical smoke exhaust uses fans and duct systems installed in the building to force smoke out. The air supply system is to supplement the negative pressure that may be formed inside the building during the smoke exhaust process, ensure that there is enough fresh air for people to breathe, and prevent smoke backflow.

[0003] During ventilation, traditional ventilation fans are installed in fixed positions on the wall. Therefore, when thick smoke appears at the fire point, the fixed ventilation fans cannot exhaust the smoke in a timely and effective manner. Therefore, there is an urgent need for a fire safety ventilation device that can move to the vicinity of the thick smoke to exhaust smoke. Utility Model Content

[0041] The following is a combination of specific implementation cases and attached Figure 1-3 The present invention is further described below, but the present invention is not limited to these embodiments.

[0042] like Figure 1-3 As shown, the utility model discloses a ventilation device for fire safety, comprising: a side panel 1, a mounting seat 2, a ventilation box 3, an air inlet panel 4, an air inlet port 5, an air inlet pipe bundle 6, a transition section 7, an air guide pipe 8, a pop-up mechanism and an exhaust fan 11 structure; the mounting seat 2 is fixedly mounted on one side of the side panel 1; a mounting groove is provided on one side of the ventilation box 3, and the mounting seat 2 is buckled into the mounting groove; the air inlet panel 4 is mounted on one side of the ventilation box 3; a number of the air inlets 5 are all opened on one side of the air inlet panel 4; a pair of the air inlet pipe bundles 6 are all connected to the inner side of the air inlet panel 4, and a number of the air inlets 5 are all connected to the air inlet pipe bundle 6; a pair of the air inlet pipe bundles 6 are all connected to one side of the transition section 7; a pair of the air guide pipes 8 are respectively connected to the upper and lower sides of the transition section 7, a pair of the air guide pipes 8 are all penetrated through the wall of one side of the ventilation box 3, and a pair of the air guide pipes 8 are connected with a central pipe; the pop-up mechanism is arranged in the mounting seat 2; the exhaust fan 11 structure is connected to one side of the air guide pipe 8.

[0043] In the embodiment of the present utility model, Figure 1-3 As shown, the ejection mechanism includes: an airbag gas generator 9 and an airbag 10 ; the airbag gas generator 9 is fixedly installed in the mounting seat 2 ; and the airbag 10 is connected to the airbag gas generator 9 .

[0044] In the embodiment of the present utility model, Figure 1-3 As shown, the exhaust fan 11 includes a buffer seat 17; the buffer seat 17 is connected to one side of the transition section 7.

[0045] In the embodiment of the present utility model, Figure 1-3 As shown, it also includes: a smoke sensor 18; the smoke sensor 18 is connected to a side wall of the side plate 1.

[0046] In the embodiment of the present utility model, Figure 1-3 As shown, it also includes: a contact 19 and an alarm bell 20; the contact 19 is located inside the guide groove 15; the alarm bell 20 is electrically connected to the contact 19.

[0047] Implementation process: When a fire occurs, a large amount of harmful black smoke will be generated due to the fire. When the black smoke contacts the smoke sensor 18, since the smoke sensor 18 is electrically connected to the airbag gas generator 9 and the exhaust fan 11, the airbag gas generator 9 is activated, and a large amount of gas is instantly filled into the airbag 10, and it expands rapidly in the mounting seat 2, lifting the ventilation box 3, so that the mounting groove of the ventilation box 3 is separated from the mounting seat 2. At this time, the ventilation box 3 is separated from the side panel 1. After it is carried to the place with the most smoke, the exhaust fan 11 exhausts the airbag 10 through the hose. 12 absorbs the black smoke, and the black smoke passes through the air inlet bundle 6, the transition section 7 and the hose 12 from the air inlet 5. Since the exhaust fan 11 is installed on the wall, the smoke is discharged outside the building, and fresh air is replenished into the building to achieve the purpose of fire ventilation. In this process, the ventilation box 3 can be moved arbitrarily within a certain range, and can flexibly discharge black smoke, pushing the slide 14 and the guide column 16 in the slide 14. At this time, the guide column 16 presses the contact 19 in the guide groove 15, causing the alarm bell 20 to sound and an alarm is issued.
