[0032] In the existing straight-line smoke exhaust skylight, since the opening and closing rotating shafts are exposed outside, water is likely to accumulate at the rotating shafts in rainy and snowy weather, resulting in water leakage and rusting.
[0033] To solve this technical problem, the present utility model provides a smoke exhaust skylight 1000 to avoid water leakage and rusting at the skylight rotating shaft 22.
[0034] Please refer to Figures 1 to 4 , the smoke exhaust skylight 1000 includes:
[0035] A window frame 1, the window frame 1 is arranged around the opening at the top of the factory building, the window frame 1 is provided with a window 11, and both sides of the window frame 1 are provided with first arc-shaped strips 121, and the openings of the two first arc-shaped strips 121 are arranged opposite to each other;
[0036] Two opening and closing windows 2, the opening and closing windows 2 include a window body 21, a rotating shaft 22, and a second arc-shaped strip 23. The window body 21 covers the window 11 of the window frame 1, the rotating shaft 22 is fixed to one side of the window body 21, the rotating shaft 22 is rotatably connected to the edge of the window frame 1, the rotating shaft 22 is located in the opening of the first arc-shaped strip 121, and the second arc-shaped strip 23 is fixed to the window body 21, and the second arc-shaped strip 23 is located above the rotating shaft 22;
[0037] Among them, the opening and closing window 2 has an open state and a closed state. When in the closed state, the outer wall surface of the top end of the first arc-shaped strip 121 contacts the inner wall surface of the top end of the second arc-shaped strip 23, and the rotating shaft 22 is enclosed in the first arc-shaped strip 121 and the second arc-shaped strip 23. When changing from the closed state to the open state, the rotating shaft 22 rotates, the window body 21 rotates and opens, and the inner wall surface of the second arc-shaped strip 23 rotates and opens along the outer wall surface of the first arc-shaped strip 121.
[0038] By arranging the first arc-shaped strips 121 on both sides of the window frame 1 and arranging the second arc-shaped strip 23 on one side of the window body 21, the rotating shaft 22 of the opening and closing window 2 is covered by the first arc-shaped strip 121 and the second arc-shaped strip 23. On the premise of ensuring that the opening and closing window 2 can be normally opened and closed, the rotating shaft 22 is always in a sealed space, and the rotating shaft 22 will not be contacted by rainwater, avoiding water leakage and rusting at the skylight rotating shaft 22.
[0039] Please refer to Figure 3 , in an embodiment of the present utility model, the window frame 1 includes:
[0040] Two side plates 12, a first arc-shaped strip 121 is arranged at the top of the side plate 12, fixing plates 14 are arranged at both ends of the side plate 12, a circular groove and an annular groove are arranged on one side of the two fixing plates 14 facing each other, both ends of the rotating shaft 22 are arranged in the circular groove, and a second arc-shaped strip 23 is slidably arranged in the annular groove;
[0041] Two end plates 13, the two end plates 13 are located between the two side plates 12, the two side plates 12 and the two end plates 13 enclose to form a window 11, and the two window bodies 21 respectively cover the two halves of the window 11.
[0042] By arranging the circular groove and the annular groove, the rotation of the rotating shaft 22 and the second sliding strip can be guided, so that the opening and closing process of the opening and closing window 2 is more stable and not prone to damage.
[0043] Please refer to Figure 1 , in an embodiment of the present utility model, the middle part of the top surface of the end plate 13 protrudes compared with both sides, so that two inclined surfaces are formed on the top surface of the end plate 13, and both ends of the window body 21 cover the inclined surfaces. With this setting, the window body 21 is inclined from the middle to both sides. In heavy rain and snow weather, the rain and snow will slide along the inclined window body 21, and too much rain and snow will not accumulate on the window body 21, avoiding water accumulation on the window body 21 and also avoiding the opening and closing window 2 being crushed by snow, ensuring that the normal opening and closing of the opening and closing window 2 will not be affected.
[0044] Please refer to Figure 2 and Figure 4 , in an embodiment of the present utility model, a sealing strip 211 is arranged on one side of the window body 21 facing the end plate 13, and a sealing groove 131 is concavely arranged on the top surface of the end plate 13. When the opening and closing window 2 is in the closed state, the sealing strip 211 is located in the sealing groove 131. With this setting, the sealing performance between the window body 21 and the end plate 13 when the opening and closing window 2 is in the closed state is improved, and the phenomenon of water leakage is further avoided.
[0045] Please refer to Figure 3 and Figure 4 , in an embodiment of the present utility model, a drain groove 212 is arranged on the top surface of the window body 21, and the drain groove 212 is arranged adjacent to the second arc-shaped strip 23. By arranging the drain groove 212, the rainwater on the window body 21 can enter the drain groove 212 when sliding along the top surface of the window body 21, and is uniformly discharged by the drain groove 212 to a position where the sealing performance of the window body 21 will not be affected, further avoiding the possibility of water accumulation on the top surface of the window body 21.
[0046] In this embodiment, the drainage trough 212 is inclined from the middle to both sides. With this arrangement, since the drainage trough 212 is inclined, the rainwater entering the drainage trough 212 flows out towards both sides of the drainage trough 212 at an accelerated speed, preventing the drainage speed of the drainage trough 212 from being unable to keep up when the rain is heavy and ensuring that the drainage trough 212 will not overflow due to heavy rain.
[0047] Please refer to Figure 3 , in an embodiment of the present utility model, a water baffle 24 is provided above the connection of the two opening and closing windows 2, and the water baffle 24 is fixed to one of the opening and closing windows 2. When two opening and closing windows 2 are provided, the sealing performance at the connection of the two opening and closing windows 2 is prone to be weak. In this solution, the water baffle 24 is provided to block the rainwater falling towards the connection of the two opening and closing windows 2 and prevent the rainwater from flowing in from the connection of the two opening and closing windows 2. At the same time, since the water baffle 24 is located on one opening and closing window 2, when the opening and closing window 2 is opened, the opening and closing window 2 provided with the water baffle 24 is opened first, and the opening and closing window 2 not provided with the water baffle 24 is opened later. When the opening and closing window 2 is closed, the opening and closing window 2 not provided with the water baffle 24 is closed first, and the opening and closing window 2 provided with the water baffle 24 is closed later. In this way, the normal opening and closing of the two opening and closing windows 2 can be ensured.
[0048] In this embodiment, the water baffle 24 is of an arc structure. The arc-shaped water baffle 24 can guide the rainwater to a position far from the connection of the two opening and closing windows 2.
[0049] Please refer to Figure 2 and Figure 4 , in an embodiment of the present utility model, the smoke exhaust skylight 1000 further includes a driving member. The driving member is located inside the window 11, and the driving member is used to drive the opening and closing window 2 to open or close. By using an electric or pneumatic driving member to drive the opening and closing of the opening and closing window 2, there is no need for manual operation to open and close the skylight, which is convenient to use.
[0050] Among them, the driving member is an electric push rod 3. The number of electric push rods 3 is two. One end of the electric push rod 3 is rotatably connected to the inner wall of the window frame 1, so that the electric push rod 3 swings around the inner wall of the window frame 1 as the axis center. The driving shaft of the electric push rod 3 is rotatably connected to the window body 21. When the electric push rod 3 is started, the opening and closing window 2 is opened. With this arrangement, the opening and closing control of the opening and closing window 2 is relatively convenient. A control module can be set. For example, the electric push rod 3 can be set to open and close the skylight at a fixed time every day. The control module is provided with a sensor to automatically close the skylight on rainy days and automatically open the skylight in case of a fire so that the smoke can be discharged from the skylight. At the same time, since each opening and closing window 2 is controlled by a separate electric push rod, the two opening and closing windows 2 can be opened and closed out of sync to meet the requirement that the two opening and closing windows 2 need to open and close out of sync due to the provision of the water baffle 24.
[0051] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
