Description

Technical Field

[0001] The utility model relates to the technical field of fire protection ventilation, in particular to a fire protection safety ventilation device. Background Art

[0002] In modern architectural design, skylights, as a crucial element, are widely used to enhance indoor lighting and ventilation, improving living and working comfort. However, as buildings age, skylight maintenance becomes increasingly problematic, particularly regarding surface cleanliness, which significantly impacts both lighting quality and the building's appearance.

[0003] Currently, most buildings on the market use fire smoke exhaust skylights installed on the roof to quickly exhaust harmful smoke and ensure the safety of people inside in the event of a fire. However, these skylights are often located at the top of the building, making frequent manual cleaning difficult. This leads to the accumulation of dust, dirt, and other impurities on the glass surface. Over time, these stains not only reduce the light transmittance of the skylights, affecting the indoor lighting, but also have a negative impact on the overall aesthetics of the building.

[0004] In order to solve the above problems, most existing fire smoke exhaust skylight systems only focus on smoke exhaust efficiency and safety performance, but ignore the daily cleaning and maintenance of the skylight. Therefore, in order to solve the above problems, we propose a fire safety ventilation device. Utility Model Content

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0022] Reference Figure 1-4 The fire safety ventilation device includes a roof 1, an opening is opened at the top of the roof 1, a longitudinal beam 2 is fixedly installed at the bottom of the roof 1, two cross beams 10 are fixedly installed between the two longitudinal beams 2, a window frame 3 is fixedly installed at the top of the opening, a rotating shaft 6 is rotatably installed on both sides of the top of the roof 1, and a skylight 4 is fixedly installed on the outer surface of the two rotating shafts 6, and the skylight 4 is adapted to the window frame 3; a driving mechanism is movably installed on the opposite side of the two cross beams 10, a transmission mechanism is rotatably installed between the two longitudinal beams 2, and the driving assembly is connected to the skylight 4 through the transmission mechanism, and a cleaning assembly is slidably installed on the top of the skylight 4, and a linkage mechanism is rotatably installed on both sides of the top of the roof 1, and the rotating shaft 6 is connected to the cleaning assembly through the linkage mechanism.

[0023] The driving assembly can drive the skylight 4 to rotate around the rotating shaft 6 through the transmission mechanism, so that the skylight 4 can move away from or close to the window frame 3, and can be opened and closed. When the skylight 4 is opened, ventilation and smoke exhaust can be achieved in the house to ensure fire safety.

[0024] When the skylight 4 is opened, the skylight 4 will drive the cleaning component to slide through the linkage mechanism, and the cleaning component can wipe the surface of the skylight 4 to clean the skylight 4 and ensure the lighting effect of the skylight 4.

[0025] The transmission mechanism includes a rotating shaft 3 11, two push rods 15 and two connecting rods 14. One end of the connecting rod 14 is rotatably connected to one end of the push rod 15, and the other end of the connecting rod 14 is movably connected to one side of the bottom of the sunroof 4. One end of the push rod 15 is fixedly connected to the outer surface of the rotating shaft 3 11, and the rotating shaft 3 11 is rotatably installed between the two longitudinal beams 2.

[0026] The rotating shaft 3 11 is a core transmission component, and its rotation transmits power to the push rod 1 15. The push rod 15 rotates and pushes or pulls the sunroof 4 through the connecting rod 14 to realize the opening or closing action of the sunroof 4.

[0027] The driving mechanism includes a cylinder 12 and a driving rod 13. The cylinder 12 is rotatably installed on one side of the beam 10. The output end of the cylinder 12 is movably connected to one end of the driving rod 13, and the other end of the driving rod 13 is fixedly connected to the outer surface of the rotating shaft 3 11.

[0028] When cylinder 12 is operating, its output end pushes drive rod 13, which in turn rotates shaft 3 11. As shaft 3 11 rotates, connecting rod 1 145, under the action of push rod 1, pushes or pulls sunroof 4, causing sunroof 4 to move away from or toward window frame 3, achieving an open or closed state.

[0029] The cleaning assembly includes two cleaning plates 5, a connecting rod 18, and four sliders 20. Slide rails 19 are fixedly installed on both sides of the top of the skylight 4, and two sliders 20 are fixedly installed on both sides of the bottom of the cleaning plate 5. The cleaning plate 5 is slidably connected to the two slide rails 19 through the two sliders 20 at the bottom, and a connecting rod 18 is fixedly installed between the two cleaning plates 5.

[0030] The cleaning plate 5 slides on the slide rail 19 through the slider 20 at the bottom to ensure close contact and smooth sliding with the surface of the skylight 4. Common cleaning tools such as a cleaning sponge or a cleaning cloth can be installed at the bottom of the cleaning plate 5.

[0031] The linkage mechanism includes a rotating shaft 27, a push rod 216, a connecting rod 217, a gear 18, and a gear 29. The rotating shaft 27 is rotatably installed on the top of the roof 1. The two rotating shafts 27 are respectively located on one side of the two rotating shafts 16. One end of the rotating shaft 16 is fixedly installed with a gear 18, and one end of the rotating shaft 27 is fixedly installed with a gear 29. The gear 18 is meshed with the gear 29. The push rod 216 is fixedly installed on the outer surface of the rotating shaft 27. One end of the push rod 216 is rotatably installed with a connecting rod 217. One end of the connecting rod 217 is movably connected to the outer surface of the connecting rod 18.

[0032] The linkage mechanism synchronizes the opening and closing of the sunroof 4 through shaft 2 (7), push rod 2 (16), connecting rod 2 (17), gear 1 (8), and gear 2 (9). When the sunroof 4 opens or closes, shaft 1 (6) rotates gear 1 (8), which meshes with gear 2 (9), thereby driving shaft 2 (7). The rotation of shaft 2 (7) drives push rod 2 (16), which, through connecting rod 2 (17), pushes or pulls connecting rod 18, driving cleaning plate 5 to slide along slide rail 19, cleaning the surface of the sunroof 4.
