Technical Field

[0001] The utility model relates to the technical field of lightweight air film structures, in particular to a lightweight air film structure. Background Art

[0002] Lightweight air-film structure is a new type of building structure and an important branch of lightweight space structure. Air-film building uses special building membrane materials as the outer shell and is equipped with a set of intelligent electromechanical equipment to provide positive air pressure inside the air-film building to support the main body of the building. The entire structure is lighter than traditional buildings.

[0003] For example, a Chinese patent (publication number: CN207032490U) discloses an air-supported building structure and an air-supported building with a snow removal function, comprising: a membrane layer, wherein a track device is provided on the outer surface of the membrane layer along the curvature direction, and two groups of sliding cover plate assemblies are symmetrically provided on the track device along the width direction of the membrane layer. The two groups of sliding cover plate assemblies can be opened downward or closed upward along the curvature direction of the membrane layer, thereby solving the technical problem that snow is easily accumulated in the top area of the existing air-supported building.

[0004] However, the above-mentioned search patent still has some shortcomings. Its membrane layer structure is relatively simple, which makes the heat insulation effect of the air-film building structure poor. When exposed to the sun for a long time, the heat will slowly penetrate the membrane layer, making the activity space inside the air-film structure stuffy and inconvenient to use. Therefore, a lightweight air-film structure is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lightweight air film structure, comprising a base frame, on which an air film mechanism is arranged;

[0007] The air film mechanism includes an inner film layer fixed on the outer peripheral wall of the base frame, a plurality of support bars are fixed on the side of the inner film layer facing away from the base frame, an outer film layer is fixed on the side of the support bars facing away from the inner film layer, a mounting hole is provided on the top surface of the base frame, an annular plate is slidably connected in the mounting hole, a mounting assembly for fixing the annular plate is provided in the mounting hole, a fan is fixed between the inner walls of the annular plates, a circular hole is provided on the top surface of the inner film layer, a plurality of ventilation pipes are fixed on the outer peripheral wall of the outer film layer, and a heating wire is fixed between the inner walls of the annular plates.

[0008] Further, the installation assembly includes two U-shaped plates fixed on the inner top wall of the base frame. A support plate is fixed between the front and rear inner walls of the U-shaped plate. A reset rod is slidably connected to the top surface of the support plate. The bottom end of the reset rod is hinged to a flip plate. A limiting block is fixed on one side of the flip plate facing the annular plate. A limiting groove is formed on the bottom surface of the annular plate. A limiting plate is fixed to the top end of the reset rod. A spring is sleeved on the outer peripheral wall of the reset rod.

[0009] Further, the base frame, the inner membrane layer and the outer membrane layer are all semi-circular structures, and the inner walls of the inner membrane layer and the outer membrane layer are both hollow structures.

[0010] Further, the support bars are arc-shaped plates, and a plurality of the support bars are equidistantly distributed along the circumferential direction of the circular hole. The top end of the annular plate extends into the circular hole.

[0011] Further, the ventilation pipes are close to the bottom surface of the outer membrane layer, and a plurality of the ventilation pipes are circularly and equally angularly distributed.

[0012] Further, the openings of the U-shaped plates face the annular plate. The two U-shaped plates are respectively located on the left and right sides of the installation holes.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] Please refer to Figure 1 , a lightweight air film structure in this embodiment includes a base frame 1, and an air film mechanism 2 is arranged on the base frame 1. When in use, the air film mechanism 2 forms a double-layer structure, which cooperates with the base frame 1 to make the structure more firm. At the same time, there is a certain space for ventilation and heat insulation between the double-layer structures, which can effectively reduce the high temperature brought by direct sunlight, avoid the sultriness of the internal activity space of the structure, improve the heat insulation effect of the air film mechanism 2, and has better practicability and is more convenient for popularization and use.

[0025] It should be noted that the control method of this application is controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in the art, and this application is mainly used to protect mechanical devices, so the control method and circuit connection of this application will not be explained in detail.

[0026] Please refer to Figures 1 to 3, the air film mechanism 2 includes an inner film layer 201 fixed on the outer peripheral wall of the base frame 1. On the side of the inner film layer 201 facing away from the base frame 1, a plurality of support bars 202 are fixed. On the side of the plurality of support bars 202 facing away from the inner film layer 201, an outer film layer 203 is fixed. The base frame 1, the inner film layer 201, and the outer film layer 203 are all semi-circular structures. The interiors of the walls of the inner film layer 201 and the outer film layer 203 are both hollow structures. When in use, by inflating the interiors of the inner film layer 201 and the outer film layer 203, the internal air supports the inner film layer 201 and the outer film layer 203. The inner film layer 201 and the outer film layer 203 are connected and fixed by the support bars 202, and cooperate with the base frame 1 to form a stable structure. At the same time, the double-layer structure is more conducive to heat insulation. An installation hole 204 is opened on the top surface of the base frame 1. A circular plate 205 is slidably connected in the installation hole 204. An installation component 3 for fixing the circular plate 205 is provided in the installation hole 204. A fan 206 is fixed between the inner walls of the circular plate 205. A circular hole 207 is opened on the top surface of the inner film layer 201. A plurality of ventilation pipes 208 are fixed on the outer peripheral wall of the outer film layer 203. When the sun shines for a long time in summer, the fan 206 is started, and air is blown through the circular plate 205 and the circular hole 207 into the gap between the inner film layer 201 and the outer film layer 203. Further, a ventilation duct is formed by the support bars 202, and the air is discharged from the ventilation pipes 208, so that the heat on the outer film layer 203 can be discharged in time when transferring to the inner film layer 201, achieving a good heat insulation effect. A heating wire 209 is fixed between the inner walls of the circular plate 205. The fan 206 and the heating wire 209 cooperate to achieve the effect of conveying hot air, which can heat the outer film layer 203 in snowy days, and then quickly melt the snow to avoid crushing the air film mechanism 2 and ensure the safe use of the air film mechanism 2.

[0027] The support bar 202 is an arc-shaped plate. Such a structure is convenient for dividing the ventilation space between the inner film layer 201 and the outer film layer 203 into multiple ventilation channels, facilitating the discharge of heat. The plurality of support bars 202 are evenly distributed along the circumferential direction of the circular hole 207. The top end of the circular plate 205 extends into the circular hole 207. The ventilation pipes 208 are close to the bottom surface of the outer film layer 203. The plurality of ventilation pipes 208 are circularly and equally angularly distributed.

[0028] Please refer to Figures 1 to 5, in this embodiment, the installation component 3 includes two U-shaped plates 301 fixed to the inner top wall of the base frame 1. A support plate 302 is fixed between the front and rear inner walls of the U-shaped plate 301. A reset rod 303 is slidably connected to the top surface of the support plate 302. The bottom end of the reset rod 303 is hinged to a flip plate 304. A limiting block 305 is fixed to the side of the flip plate 304 facing the annular plate 205. A limiting groove 306 is formed in the bottom surface of the annular plate 205. The opening of the U-shaped plate 301 faces the annular plate 205. The two U-shaped plates 301 are respectively located on the left and right sides of the mounting hole 204. A sliding hole for the reset rod 303 to pass through and be slidably connected thereto is formed in the top surface of the support plate 302. When it is necessary to disassemble the annular plate 205 for overhauling the fan 206, the two flip plates 304 are pulled downward, driving the reset rod 303 and the limiting block 305 to move downward, so that the limiting block 305 disengages from the limiting groove 306. When the bottom end of the reset rod 303 extends to the bottom of the U-shaped plate 301, the flip plate 304 can be flipped at this time, and then it is convenient to slide the annular plate 205 downward to disengage from the mounting hole 204 to complete the disassembly. A limiting plate 307 is fixed to the top end of the reset rod 303. A spring 308 is sleeved on the outer peripheral wall of the reset rod 303. The spring 308 is arranged between the limiting plate 307 and the support plate 302. The flip plate 304 is a rectangular plate and is slidably connected to the inner wall of the U-shaped plate 301. When the reset rod 303 moves downward, it will also drive the limiting plate 307 to move downward to compress the spring 308, so as to reset the flip plate 304 through the spring 308 during installation, and then limit and install the annular plate 205 through the cooperation of the U-shaped plate 301, the flip plate 304 and the limiting block 305.

[0029] The working principle of the above embodiment is as follows:

[0030] (1) During use, by inflating the inner membrane layer 201 and the outer membrane layer 203, the internal air supports the inner membrane layer 201 and the outer membrane layer 203. The inner membrane layer 201 and the outer membrane layer 203 are connected and fixed by the support bars 202, and cooperate with the base frame 1 to form a stable structure. At the same time, the double-layer structure is more conducive to heat insulation. When the sun shines for a long time in summer, the fan 206 is started, and the annular plate 205 cooperates with the circular hole 207 to blow air into the gap between the inner membrane layer 201 and the outer membrane layer 203. Further, the air duct is formed by the support bars 202, and the air is discharged from the ventilation pipe 208, so that the heat on the outer membrane layer 203 can be discharged in time when it is transferred to the inner membrane layer 201, achieving a good heat insulation effect;

[0031] (2) When it is necessary to disassemble the annular plate 205 for maintenance of the fan 206, pull the two flip plates 304 downward, driving the reset rod 303 and the limit block 305 to move downward, so that the limit block 305 disengages from the limit groove 306. When the bottom end of the reset rod 303 extends to the bottom of the U-shaped plate 301, the flip plate 304 can be flipped at this time, and then it is convenient to slide the annular plate 205 downward out of the mounting hole 204 to complete the disassembly. When the reset rod 303 moves downward, it will also drive the limit plate 307 to move downward to compress the spring 308, so as to reset the flip plate 304 through the spring 308 during installation, and then limit and install the annular plate 205 through the cooperation of the U-shaped plate 301, the flip plate 304 and the limit block 305.
