Abstract
Description
Technical Field
[0001] This invention relates to the field of air-supported membrane technology, and more specifically, to an air-supported membrane structure for a rotary opening and closing roof. Background Technology
[0002] The full name of an air-supported membrane structure is air-supported membrane structure. It is a new type of building that has emerged with the development of new materials and technologies. An air-supported membrane stadium is a building structure system that uses special architectural membrane materials as its outer shell.
[0003] Currently, different sports venues can be set up according to the corresponding sports projects. Most of the traditional air-supported membrane stadiums are now enclosed buildings. For example, patent application 201721664467.1 discloses a stadium based on a combination structure of a statically indeterminate ring truss and a cable dome, which includes an outer statically indeterminate ring truss structure and a cable dome structure. The outer statically indeterminate ring truss structure includes load-bearing piers, load-bearing columns, struts, and truss rods; the cable dome structure includes an upper chord ridge cable, a lower chord inclined cable, an outer ring beam, an inner ring beam, and compression members; the outer statically indeterminate ring truss structure is fixed to the ground, providing the necessary constraint force to balance the huge tensile force generated by the cable dome structure roof. The cable dome structure forms a self-stressed spatial structure system through the upper chord ridge cable, the lower chord inclined cable, and the compression members; the outer ends of the outer upper chord ridge cable and the lower chord inclined cable in the cable dome structure are fixed to the outer statically indeterminate ring truss structure, and the outer ring beam, inner ring beam, and compression members in the cable dome structure fix the shape of the overall structure.
[0004] When there are many people inside the stadium and the stadium is closed, the internal temperature will rise and it will become stuffy. At this time, it is necessary to increase the ventilation and cooling equipment of the stadium, which will result in greater energy consumption. If this continues for a long time, the ventilation equipment may overheat and fail to operate normally, which may make the stadium too stuffy. In addition, the traditional open stadium cannot effectively resist wind and rain. Summary of the Invention

[0011] Optionally, one end of the first air membrane is fixedly connected to the side wall of the mounting frame, the first air membrane is connected to the mounting frame, and an inflation port connected to the first air membrane is provided inside the mounting frame.
[0012] Optionally, the first air film may be provided in several forms.
[0013] Optionally, a protective plate is fixedly connected to the side wall of the support frame, and the protective plate is located on one side of the movable groove.
[0014] Optionally, the opening and closing mechanism includes a fixed plate, a movable frame, a first guide rod, and a mounting plate. The mounting frame has a through hole inside, the mounting plate is disposed inside the mounting frame, the fixed plate is fixedly connected inside the mounting frame, the movable frame is located between the bottom of the fixed plate and the top of the mounting plate, the mounting plate has a limiting groove inside, the bottom of the movable frame is fixedly connected to a limiting block that matches the limiting groove, the fixed plate has a first guide groove inside, the top of the movable frame is fixedly connected to a first guide rod that matches the first guide groove, and the movable frame is movably connected between the fixed plate and the mounting plate through the limiting block and the first guide rod.

One end of the hydraulic rod is movably connected inside the fixing component, and the other end of the hydraulic rod is movably connected to the side wall of the second guide rod.
[0019] 3. Beneficial effects
[0020] Compared with the prior art, the advantages of this invention are:
[0021] (1) This solution uses an automatic storage mechanism. When the air-supported membrane structure needs to be adjusted to an open structure, the inflation is stopped first. Then, the servo motor is started to rotate the gear shaft. When the gear shaft rotates, the first air-supported membrane can be rolled up to the top of the support frame inside the movable slot, thus adjusting the air-supported membrane structure to an open structure. When the open structure needs to be adjusted to a closed structure, the servo motor is simply driven to rotate the gear shaft to lower the first air-supported membrane. Then, the first air-supported membrane is inflated through the inflation port. This allows the structure to be freely converted between closed and open structures, so that it can be converted according to needs.
[0022] (2) By setting an opening and closing mechanism, when it is necessary to open the roof of the building, by setting a hydraulic rod, when the hydraulic rod is retracted, it can drive the second guide rod at one end of the hydraulic rod to move inside the second guide groove, so that the mounting plate rotates inside the mounting frame. When the mounting plate rotates, since the first guide rod at the top of the movable frame is located in the first guide groove inside the fixed plate, and the limiting block at the bottom of the movable frame is located in the limiting groove inside the mounting plate, the movable frame will move between the bottom of the fixed plate and the mounting plate, and under the guidance of the limiting block and the first guide rod, it will slide obliquely to the outside of the through hole along the limiting groove and the first guide groove, so that the through hole is leaked out, allowing external air to enter the equipment through the through hole, so that it can achieve the function of freely opening and closing the roof.
[0023] (3) By setting up baffles, rainwater can be prevented from flowing into the first guide groove when it rains, and the top of the fixed plate can be protected. The movable frame has an inlet, which matches the limiting groove. The limiting groove has a connecting port, and the support frame has an outlet, which corresponds to the connecting port. When it rains, the rainwater falling on the top of the mounting frame will flow to the ground through the outer wall of the first air membrane under the guidance of the baffle. The rainwater falling on the second air membrane will flow into the limiting groove through the inlet. When the movable frame is closed, the rainwater in the limiting groove will flow into the outlet inside the support frame through the connecting port and then be discharged from the outlet, preventing rainwater from flowing into the interior from the top when it rains.
[0024] (4) By setting matching parts and matching slots, when the six movable frames move, the matching parts on one side of one movable frame will slide into the matching slot inside another movable frame, which plays a guiding role and prevents the movable frame from tilting when it moves. By setting matching parts and matching slots, rainwater flowing in through the gaps between the movable frames can be reduced when the movable frames are closed on rainy days.

[0039] Please see Figures 1-10This invention provides a rotary opening and closing air-supported membrane structure for roofs, including a mounting frame 1 and several support frames 2 arranged in a circular array on the side wall of the mounting frame 1. The air-supported membrane structure includes: an automatic storage mechanism, located inside the support frames 2, for storing and unfolding a first air-supported membrane 5; and an opening and closing mechanism, located inside the mounting frame 1, for opening and closing the roof.

The support frame 2 has a connecting groove 9 inside, and the gear shaft 8 is movably connected inside the connecting groove 9. By setting the connecting groove 9, the movement trajectory of the gear shaft 8 can be limited. The gear end of the gear shaft 8 is located inside the movable groove 6, and the gear at one end of the gear shaft 8 meshes with the teeth 7. By making the gear shaft 8 mesh with the teeth 7, it can move inside the movable groove 6 when the gear shaft 8 rotates. By setting an automatic storage mechanism, the first air membrane 5 can be retracted or lowered by controlling the operation of the servo motor 12, thereby freely switching between closed and open buildings.
[0040] In some embodiments, see Figure 1 , Figure 4 One end of the first air membrane 5 is fixedly connected to the side wall of the mounting frame 1. The first air membrane 5 is connected to the mounting frame 1. An inflation port 22 connected to the first air membrane 5 is provided inside the mounting frame 1. By setting the inflation port 22, when the first air membrane 5 needs to be supported, air only needs to be inflated into the inflation port 22 to support the first air membrane 5. There are several first air membranes 5. There are six first air membranes 5. The six first air membranes 5 are respectively set between two adjacent support frames 2. A protective plate 3 is fixedly connected to the side wall of the support frame 2. The protective plate 3 is located on one side of the movable groove 6. By setting the protective plate 3, the components inside the movable groove 6 of the support frame 2 can be protected, and the strength of the support frame 2 can be enhanced.
[0041] In some embodiments, see Figure 5 , Figure 6 , Figure 7 , Figure 8The opening and closing mechanism includes a fixed plate 13, a movable frame 15, a first guide rod 16, and a mounting plate 18. The mounting frame 1 has a through hole 20 inside. The mounting plate 18 is located inside the mounting frame 1. The fixed plate 13 is fixedly connected inside the mounting frame 1. The movable frame 15 is located between the bottom of the fixed plate 13 and the top of the mounting plate 18. The mounting plate 18 has a limiting groove 19 inside. A limiting block 30 matching the limiting groove 19 is fixedly connected to the bottom of the movable frame 15. The fixed plate 13 has a first guide groove 14 inside. A first guide rod 16 matching the first guide groove 14 is fixedly connected to the top of the movable frame 15. The movable frame 15 is movably connected between the fixed plate 13 and the mounting plate 18 via the limiting block 30 and the first guide rod 16. The opening and closing mechanism also includes a fixing element 24, a hydraulic rod 25, and a second guide rod 26. The mounting frame 1 has a second guide groove 23 inside. The second guide rod 26 is fixedly connected to the bottom of the mounting plate 18, and the second guide rod 26 is aligned with the second guide groove 24. 3. Matching, the fixing part 24 is fixedly connected to the bottom of the mounting frame 1. One end of the hydraulic rod 25 is movably connected to the inside of the fixing part 24, and the other end of the hydraulic rod 25 is movably connected to the side wall of the second guide rod 26. By setting the hydraulic rod 25, when the hydraulic rod 25 is retracted, it can drive the second guide rod 26 at one end of the hydraulic rod 25 to move inside the second guide groove 23, so that the mounting plate 18 rotates inside the mounting frame 1. When the mounting plate 18 rotates, since the first guide rod 16 at the top of the movable frame 15 is located in the first guide groove 14 inside the fixed plate 13, and the limiting block 30 at the bottom of the movable frame 15 is located in the limiting groove 19 inside the mounting plate 18, the movable frame 15 will move between the bottom of the fixed plate 13 and the mounting plate 18, and under the guidance of the limiting block 30 and the first guide rod 16, it will slide obliquely to the outside of the through hole 20 along the limiting groove 19 and the first guide groove 14, so that the through hole 20 leaks out, allowing external air to enter the equipment through the through hole 20, so that it can achieve the function of opening and closing the roof.
[0042] In some embodiments, see Figure 9 , Figure 10The movable frame 15 has a second air membrane 17 fixedly connected inside. There are six movable frames 15 in total. A baffle 4 is fixedly connected to the top of the fixed plate 13. The baffle 4 prevents rainwater from flowing into the first guide groove 14 during rain and protects the top of the fixed plate 13. The movable frame 15 has a water inlet 27 that matches the limiting groove 19. The limiting groove 19 has a connecting port 21. The support frame 2 has a water outlet 10, with the connecting port 21 corresponding to the water outlet 10. When it rains, rainwater falling on the top of the mounting frame 1 will be guided by the baffle 4 and flow down the outer wall of the first air membrane 5 to the ground. Rainwater falling on the second air membrane 17 will flow through the water inlet 27 to the limiting groove. Inside the 19, when the movable frame 15 is closed, rainwater inside the limiting groove 19 will flow into the outlet 10 inside the support frame 2 through the connecting port 21, and then be discharged from the outlet 10. A matching part 28 is fixedly connected to one side of the movable frame 15, and a matching groove 29 matching the matching part 28 is opened on the other side of the movable frame 15. By setting the matching part 28 and the matching groove 29, when the six movable frames 15 move, the matching part 28 on one side of the movable frame 15 will slide into the matching groove 29 inside the other movable frame 15, which plays a guiding role and prevents the movable frame 15 from tilting when it moves. By setting the matching part 28 and the matching groove 29, when the movable frame 15 is closed on rainy days, the amount of rainwater flowing in through the gaps between the movable frames 15 can be reduced.
[0043] The servo motor 12 and hydraulic rod 25 involved in this embodiment can be freely configured according to the actual application scenario, and the operation of the servo motor 12 and hydraulic rod 25 adopts the methods commonly used in the prior art.
[0044] The workflow and principle of this invention are as follows: When the air-supported membrane structure needs to be adjusted to an open structure, inflation is stopped. Then, the servo motor 12 is started, causing the gear shaft 8 at its output end to rotate. By engaging the gear shaft 8 with the teeth 7, the gear shaft 8 can move inside the movable slot 6 during rotation. The movement trajectory of the gear shaft 8 can be limited by the connecting slot 9. The fixing frame 11 is fixedly installed inside the first air-supported membrane 5. When the servo motor 12 inside the fixing frame 11 moves, it can drive the first air-supported membrane 5 to move. When the gear shaft 8 rotates to the top of the movable slot 6, the first air-supported membrane 5 will roll up to the top of the support frame 2, thus adjusting the air-supported membrane structure to an open structure. When the open structure needs to be adjusted to a closed structure, simply rotate the gear shaft 8 driven by the servo motor 12 to cover the first air-supported membrane 5 between the two connected support frames 2, and then inflate. Inflation can be performed by filling the first air film 5 with air through port 22. When it is necessary to open the roof of the building, a hydraulic rod 25 is installed. When the hydraulic rod 25 is retracted, it can drive the second guide rod 26 at one end of the hydraulic rod 25 to move inside the second guide groove 23, so that the mounting plate 18 rotates inside the mounting frame 1. When the mounting plate 18 rotates, since the first guide rod 16 at the top of the movable frame 15 is located in the first guide groove 14 inside the fixed plate 13, and the limiting block 30 at the bottom of the movable frame 15 is located in the limiting groove 19 inside the mounting plate 18, the movable frame 15 will move between the bottom of the fixed plate 13 and the mounting plate 18. Under the guidance of the limiting block 30 and the first guide rod 16, it will slide obliquely outward along the limiting groove 19 and the first guide groove 14 towards the outside of the through hole 20, so that the through hole 20 leaks out, allowing external air to enter the equipment through the through hole 20, so as to achieve the function of opening and closing the roof.
