Description

Technical Field

[0001] This utility model belongs to the field of fire-fighting skylight technology, and in particular relates to a rapid drainage structure for fire-fighting skylights. Background Technology

[0002] Fire-fighting skylights are special windows installed on the roof or walls of buildings. They possess multiple functions, including fire prevention, smoke extraction, and lighting, playing a crucial role in emergencies such as fires. During a fire, smoke and toxic gases rapidly fill the building, posing a serious threat to lives and property. Fire-fighting skylights can be opened promptly to create smoke extraction channels, effectively removing smoke and toxic gases, reducing temperature and smoke concentration within the fire area, and providing favorable conditions for firefighting and rescue operations. The design of rapid drainage structures is crucial for fire-fighting skylights, especially fire-fighting smoke extraction skylights, to ensure rapid drainage of accumulated water and prevent leakage under severe weather conditions, such as heavy rain.

[0003] The problem with existing technology is that long-term water accumulation may cause the sealing material of the skylight to age or be damaged, thus losing its waterproof performance. Furthermore, water that remains on the skylight for a long time will cause continuous pressure and erosion on its structure. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a rapid drainage structure for fire skylights, which has the advantage of quickly cleaning up water accumulated on the skylights. It solves the problem that long-term water accumulation may cause the sealing material of the skylight to age or be damaged, thus losing its waterproof performance, and that long-term retention of water on the skylight will cause continuous pressure and erosion on its structure.

[0005] This utility model is implemented as follows: a rapid drainage structure for a fire-fighting skylight includes a base, a window body, and a skylight. The window body is fixedly connected to the top of the base, and the skylight is rotatably connected to the top of the skylight via a pivot. Drainage grooves are provided on both the front and rear sides of the top of the base, with the edges of the drainage grooves flush with the edges of the window body and the skylight.

Detailed Implementation

[0021] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 5As shown, the rapid drainage structure of the fire skylight provided in this embodiment of the utility model includes a base 1, a window 2 and a skylight 3. The window 2 is fixedly connected to the top of the base 1, and the skylight 3 is rotatably connected to the top of the skylight 3 via a pivot. Drainage grooves 4 are provided on both the front and rear sides of the top of the base 1. The edges of the drainage grooves 4 are flush with the edges of the window 2 and the skylight 3. Placement racks 5 are fixedly connected to both the left and right sides of the top of the base 1, and the placement racks 5 are located directly above the drainage grooves 4. A screw rod 6 is rotatably connected between the placement racks 5, and a cleaning device 7 is threaded onto the surface of the screw rod 6. A driving device 8 is fixedly connected to the left side of the top of the base 1.

[0024] refer to Figure 1 , Figure 4 and Figure 5 The cleaning device 7 includes a crossbar 701, two push rods 702, two electric cylinders 703, and a push plate 704. The crossbar 701 is threaded to the surface of the lead screw 6. The two push rods 702 are fixedly connected to the front and rear sides of the bottom of the crossbar 701, and the position of the push rods 702 corresponds to the position of the drainage trough 4. The push rods 702 extend to the bottom of the drainage trough 4. The two electric cylinders 703 are fixedly connected to the front and rear sides of the top of the crossbar 701, and the output end of the electric cylinder 703 passes through and extends out of the bottom of the crossbar 701. The push plate 704 is fixedly connected to the output end of the two electric cylinders 703, and the length of the push plate 704 is the same as that of the skylight 3.

[0025] The above solution is adopted: by setting up a cleaning device 7, rainwater on the surface of the skylight 3 can be cleaned by the cleaning device 7, and then the cleaned rainwater falls into the drainage channel 4 and is pushed out by the push rod 702 for drainage.

[0026] refer to Figure 1 and Figure 4 The drive device 8 includes a motor 801, a pulley 802, two driven wheels 803, and two transmission belts 804. The motor 801 is fixedly connected to the left side of the top of the base 1. The pulley 802 is fixedly connected to the output end of the motor 801. The two driven wheels 803 are rotatably connected to the left side of the two placement frames 5 respectively, and the driven wheels 803 are fixedly connected to the lead screw 6. The two transmission belts 804 are both sleeved on the surface of the pulley 802, and the other end of the transmission belt 804 is sleeved on the surface of the two driven wheels 803.

[0027] The above solution involves setting up a drive device 8 to move the cleaning device 7, thereby cleaning the rainwater on the sunroof 3.

[0028] refer to Figure 2 and Figure 3 Two support frames 12 are fixedly connected to the left side of the base 1. A protective cover 9 is fixedly connected to the top of the support frame 12, and the protective cover 9 covers the drive device 8.

[0029] The above solution is adopted: by setting up a placement rack 5 and a protective cover 9, the protective cover 9 can be placed on the placement rack 5, and then the drive device 8 can be protected by the protective cover 9.

[0030] refer to Figure 2 Inspection doors 10 are provided on one side of the protective cover 9 corresponding to the pulley 802 and the driven pulley 803 via a rotating shaft.

[0031] By adopting the above solution, by setting up the inspection door 10, it is convenient for users to inspect and maintain the pulley 802 and the driven pulley 803.

[0032] refer to Figure 1 Both sides of the drainage trough 4 are chamfered.

[0033] The above solution involves chamfering the drainage trough 4 to drain the accumulated water and prevent backflow after the water is pushed out.

[0034] refer to Figure 5 The top of the crossbar 701 is fixedly connected to the cover 11, which covers the electric cylinder 703.

[0035] By adopting the above solution, the electric cylinder 703 can be protected by setting up the cover 11, so as to prevent the electric cylinder 703 from malfunctioning after being exposed to rainwater.

[0036] The working principle of this utility model:

[0037] In use, the motor 801 is started, which drives the pulley 802 to rotate. When the pulley 802 rotates, it drives the other two driven pulleys 803 to rotate via the transmission belt 804. Then, the rotation of the driven pulleys 803 drives the two lead screws 6 to rotate. When the lead screws 6 rotate, they drive the threaded crossbar 701 to move. When the crossbar 701 moves, it drives the two electric cylinders 703 to move. Then, the electric cylinders 703 are started, and they drive the push plate 704 to move. When the push plate 704 moves, it cleans the surface of the skylight 3 and pushes the accumulated water. At this time, the accumulated water falls into the drainage grooves 4 on both sides of the base 1. Then, the push rod 702 pushes it into the drainage grooves 4.

[0038] In summary, the rapid drainage structure of this fire skylight, through the coordinated use of a base 11, window 2, skylight 3, drainage channel 4, placement rack 5, screw rod 6, cleaning device 7, drive device 8, protective cover 9, inspection door 10, and machine cover 11, solves the problem that long-term water accumulation may cause the skylight's sealing material to age or be damaged, thus losing its waterproof performance, and that long-term water retention on the skylight will cause continuous pressure and erosion on its structure.
