Description

Technical Field

[0001] The present application relates to the field of air films, and in particular to an air film device having a snow falling guiding device. Background Art

[0002] Air membrane equipment is a structural system that uses membrane material as the outer shell, and provides positive air pressure inside the membrane material shell by equipping the outer shell with intelligent electromechanical equipment, thereby providing support for the outer shell. Usually, the bottom of the air membrane is fixedly connected to the retaining wall. In snowy weather, due to the influence of factors such as the net cable, wind load and temperature on the air membrane, snow of varying thickness will form on the top and slope of the air membrane. As the temperature warms up, the part of the snow in contact with the surface of the air membrane begins to melt, causing the snow in different areas to slide along the surface of the air membrane. In the process of snow sliding, due to gravity, the snow will collide with the retaining wall connected to the bottom of the air membrane, bringing a certain impact to the bottom of the air membrane, so that the membrane surface around the bottom of the air membrane, bridges and fans and other facilities and equipment may be damaged by the impact. Furthermore, when there is too much snow on the surface of the air membrane, it is necessary to manually clear the snow from the membrane surface. The falling snow slides down the membrane surface to the lower part of the membrane, which may also cause damage to the membrane surface around the bottom of the air membrane. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the present application provides an air film device with a snow falling guiding device to solve at least one of the above-mentioned technical problems. The specific structure is as follows:

[0004] An air film device with a snowfall guiding device comprises an air film, a first connecting member, a second connecting member and a planar guiding member made of a hard plate material and / or a soft film material. A retaining wall is connected to the lower part of the air film; one end of the guiding member is fixedly connected to a preset first position of the air film through the first connecting member, and the other end is fixedly connected to the retaining wall through the second connecting member.

[0005] There is a buffer space between the guide, the air film and the retaining wall, and the guide covers the connection between the air film and the retaining wall so that the connection is located in the buffer space.

[0006] Under normal circumstances, since the air film usually has a smooth surface, when foreign objects such as falling snow fall on the surface of the air film, they can slide along the surface of the air film to the ground. When the falling snow slides from the top of the air film to the edges of the air film, it will cause impact and damage to the connection between the edges of the air film and the retaining wall. Therefore, when setting a guide on the surface of the air film, in addition to making the guide completely cover the connection between the air film and the retaining wall so that the falling snow does not directly contact the connection, it is also necessary to make sure that the impact force of the falling snow does not affect the connection. Therefore, there is a buffer space between the connection between the air film and the retaining wall and the guide. In practical applications, the buffer space can be an airtight enclosed space to reduce the impact of external air pressure or wind on the stability of the guide.

[0007] In some specific embodiments, mounting holes are provided at both ends of the guide member. The first connecting member fixes one end of the guide member at a first position through the mounting hole, and the second connecting member fixes the other end of the guide member to the retaining wall through the mounting hole.

[0008] In some specific embodiments, the edges of both ends of the guide member connecting the air film and the retaining wall are provided with reinforcement edges, and the reinforcement edges protrude relative to the guide member. In practical applications, when the guide member is made of a flexible membrane material or the like, the reinforcement edge is a rope-embedded structure provided on the edge of the guide member, and the rope-embedded structure can play a role in reinforcing the edge of the guide member.

[0009] In some specific embodiments, the reinforced edge is in close contact with one side of the first connecting member and / or the second connecting member. When the reinforced edge is in close contact with the first connecting member and / or the second connecting member, it can absorb the force from the first connecting member and / or the second connecting member, increase the friction between the connecting member and the guide member, and play an anti-slip role.

[0010] In some specific embodiments, when the guide member is a hard plate, it can be a metal plate or a non-metal plate. In practical applications, as long as the guide member can cover the connection between the air film and the retaining wall and a buffer space can be formed between the guide member and the connection between the air film and the retaining wall, the material of the guide member can be selected according to actual conditions. When the guide member is a hard plate, it is not necessary to strengthen the edge, and only the corresponding mounting holes need to be provided on the guide member.

[0011] In practical applications, there are many ways to fix the guide member to the air membrane. The guide member may be directly connected to the air membrane through a first connecting member, or indirectly connected through a buckle, a track or an auxiliary member.

[0012] In one of the connection methods between the guide and the air film, a steel cable for limiting the position of the air film is also provided on the outer surface of the air film; a plurality of steel cables have an intersection at a first position, and buckles for fixing the steel cables are provided at at least some of the intersections, and the connecting line of the plurality of buckles is parallel to the extension direction of the latitude of the air film, and the first connecting member fixes one end of the guide at the first position through the buckle. In practical applications, the buckle can be a cross-shaped buckle, and the cross-shaped buckle is provided with mounting openings at the four ends of the cross, and at the same time, the mounting hole at one end of the guide fixedly connected to the air film is arranged corresponding to the position and number of the mounting openings of the cross buckle, and the first connecting member can fix the guide to the cross-shaped buckle along the mounting opening, and further, the guide is fixed to the first position on the outer surface of the lower part of the air film through the cross-shaped buckle.

[0013] In another connection method between the guide member and the air film, a guide rail member is further included, the guide rail member is connected to a plurality of buckles, so that the plurality of buckles are connected at a first position to form a track. A through hole is provided on the guide rail member, and the first connecting member fixes one end of the guide member to the track through the through hole.

[0014] In some specific embodiments, the guide rail member includes a hoop and a guide rail body, the hoop includes a connecting portion and a tightening portion, the connecting portion is fixedly connected to the buckle, and the tightening portion is used to sleeve the guide rail body into the hoop, wherein a through hole is arranged at the top of the tightening portion, and a first connecting member passes through the through hole to fix one end of the guide member to the hoop.

[0015] In some specific embodiments, an auxiliary member is further included, one end of the auxiliary member is fixedly connected to the first position, and the other end of the auxiliary member is fixedly connected to the guide member through the first connecting member.

[0016] In some specific embodiments, the auxiliary member includes a reinforcing membrane and an auxiliary membrane, the reinforcing membrane is fixedly connected to the first position, one end of the auxiliary membrane is fixedly connected to the reinforcing membrane, and the other end is fixedly connected to the guide member through the first connecting member. In practical applications, the reinforcing membrane can be fixedly attached to the inner or outer surface of the first position of the air membrane by welding or welding a reinforcement plate. In a specific embodiment, the air membrane is a membrane material composed of a base fabric and a coating, wherein the base fabric is woven from mutually perpendicular wefts and warps. In the process of welding the reinforcing membrane, the reinforcing membrane is also woven from mutually perpendicular wefts and warps, and the extension direction of the warp and weft of the reinforcing membrane is consistent with the extension direction of the warp and weft of the air membrane, which can improve the connection strength between the air membrane and the reinforcing membrane and the strength of the air membrane itself, and further prevent the air membrane from tearing.

[0017] In some specific embodiments, a fixing member is further included, and there is an overlapping area between the auxiliary film and the guide member, and the fixing members are respectively located on both sides of the overlapping area, and the first connecting member passes through the fixing member in the overlapping area to fix the auxiliary film and the guide member in the overlapping area. In a specific embodiment, the fixing member is a fixing plate, and the reinforcement edge is close to one side of the fixing member, and the protruding part of the reinforcement edge can provide support for one side of the fixing member, increase the friction between the fixing member and the guide member, and make the connection between the guide member and the auxiliary film tighter.

[0018] In a specific embodiment, when the guide member is a hard plate material, the guide member can be a curved panel, and the curved panel is convex relative to the connection. In practical applications, the falling snow can slowly slide down along the curved panel, and the buffer space formed between the guide member, the air film and the retaining wall can further offset the impact force of the falling snow in the process of sliding down. In practical applications, further optimization effects such as waterproofing and dustproofing can be provided for the connection. When the guide member is a soft membrane material, no curved convexity will be generated, and the guide member forms a curtain at the connection between the retaining wall and the air film, wherein a closed buffer space is formed between the curtain, the retaining wall and the air film, which can effectively guide the movement of the falling snow.

[0019] In some specific embodiments, the second connecting member may be a bolt pre-embedded in the retaining wall, or an expansion bolt and / or a chemical anchor bolt.

[0020] Beneficial effects: The present application provides an air film device with a snowfall guiding device, wherein a guide is provided outside the connection between the lower outer surface of the air film and the retaining wall, and a buffer space can be formed between the guide, the air film and the connection to prevent the impact of falling snow. The guide can effectively guide the falling snow to slide down from a position far away from the connection between the air film and the retaining wall, effectively preventing the falling snow from impacting and damaging the air film surface in the process of sliding down along the air film surface, and also preventing the accumulation and erosion of rainwater and dust at the connection.

[0040] Example

[0041] The present application provides an air film device with a falling snow guiding device, which can guide the sliding of snow on the air film, reduce the impact of snow on the bottom of the air film and the connection between the retaining wall 5, and protect the air film device. The specific scheme is as follows:

[0042] An air film device with a snowfall guiding device comprises an air film 1, a first connecting member 3, a second connecting member 4 and a planar guiding member 2 made of a hard plate material and / or a soft film material. A retaining wall 5 is connected to the lower part of the air film 1; one end of the guiding member 2 is fixedly connected to a preset first position of the air film 1 through the first connecting member 3, and the other end is fixedly connected to the retaining wall 5 through the second connecting member 4. Figure 1 As shown in the middle area A, the connection position of the guide member 2 and the retaining wall 5 is shown as follows Figure 1 As shown in the middle area B, the corresponding side view is as follows Figure 2 As shown, the specific details of area A are as follows Figure 8 shown.

[0043] There is a buffer space between the guide 2, the air film 1 and the retaining wall 5, and the guide 2 covers the connection between the air film 1 and the retaining wall 5 so that the connection is located in the buffer space. Figure 2 shown.

[0044] Under normal circumstances, since the air film 1 usually has a smooth curved surface, when foreign objects such as falling snow fall on the surface of the air film 1, they can slide along the curved surface of the air film 1 to the ground. When the falling snow slides from the top of the air film 1 to the edges of the air film 1, it will cause impact and damage to the connection between the edges of the air film 1 and the retaining wall 5. Therefore, when the guide 2 is set on the surface of the air film 1, in addition to making the guide 2 completely cover the connection between the air film 1 and the retaining wall 5 so that the falling snow does not directly contact the connection, it is also necessary to make sure that the impact force of the falling snow does not affect the connection. Therefore, the buffer space set between the connection between the air film 1 and the retaining wall 5 and the guide 2 can play a buffering role. In practical applications, the buffer space can be an airtight enclosed space to reduce the influence of external air pressure or wind on the stability of the guide 2.

[0045] In some specific embodiments, both ends of the guide member 2 are provided with mounting holes 21. The first connecting member 3 fixes one end of the guide member 2 at the first position through the mounting hole 21, and the second connecting member 4 fixes the other end of the guide member 2 to the retaining wall 5 through the mounting hole 21.

[0046] In some specific embodiments, the edges of the guide member 2 connecting the air film 1 and the retaining wall 5 at both ends are provided with a reinforcement edge 22, and the reinforcement edge 22 protrudes relative to the guide member 2. In practical applications, when the guide member 2 is made of a flexible membrane material, the reinforcement edge 22 is a buried rope structure provided at the edge of the guide member 2, specifically, Figure 6 As shown, this buried rope structure can play a role in reinforcing the edge of the guide member 2.

[0047] In some specific embodiments, the reinforcing edge 22 is in close contact with one side of the first connecting member 3 and / or the second connecting member 4. When the reinforcing edge 22 is in close contact with the first connecting member 3 and / or the second connecting member 4, the force from the first connecting member 3 and / or the second connecting member 4 can be taken up, the friction between the connecting member and the guide member 2 can be increased, and the anti-slip effect can be achieved. Figure 8 shown.

[0048] In some specific embodiments, the guide member 2 is a flexible membrane material and / or a hard plate material. When the guide member 2 is a hard plate material, the guide member 2 can be a metal plate material or a non-metal plate material. In practical applications, as long as the guide member 2 covers the connection between the air film 1 and the retaining wall 5 and a buffer space is formed between the guide member 2 and the connection between the air film 1 and the retaining wall 5, the material of the guide member 2 can be selected according to actual conditions. When the guide member 2 is a hard plate material, it is not necessary to strengthen the edge, and only the mounting hole 21 needs to be provided.

[0049] In practical applications, there are many ways to fix the guide member 2 to the air membrane 1 . The guide member 2 can be directly connected to the air membrane 1 through the first connecting member 3 , or indirectly connected through the buckle 61 , a track or an auxiliary member 8 .

[0050] In one of the connection methods between the guide member 2 and the air membrane 1, a steel cable 6 for limiting the air membrane 1 is also provided on the outer surface of the air membrane 1; multiple steel cables 6 have an intersection at the first position, and at least some of the intersections are provided with buckles 61 for fixing the steel cables 6, and the connecting line of multiple buckles 61 can form a straight line, and the first connecting member 3 fixes one end of the guide member 2 to the first position through the buckle 61.

[0051] In actual applications, the buckle 61 can be a cross-shaped buckle 61, and the cross-shaped buckle 61 is respectively provided with installation openings at the four end points of the cross. At the same time, the installation hole 21 at one end of the guide member 2 fixedly connected to the air membrane 1 is set corresponding to the position and number of the installation openings of the cross buckle 61. The first connecting member 3 can be used to fix the guide member 2 on the cross-shaped buckle 61 along the installation opening. Further, the guide member 2 is fixed to the first position on the lower outer surface of the air membrane 1 through the cross-shaped buckle 61.

[0052] The position of the mounting hole 21 on the guide member 2 corresponding to the mounting hole 21 of the cross buckle 61 is set as follows: Figure 4 In practical applications, the first connecting member 3 may be a bolt, and a nut matching the bolt may be provided on the mounting opening.

[0053] It should be noted that, in this embodiment, the number of installed buckles 61 is not limited, nor is it limited to providing a buckle 61 at every intersection at the first position.

[0054] In another connection mode between the guide member 2 and the air film 1, a guide rail member 7 is further included. The guide rail member 7 is connected to a plurality of buckles 61, so that the plurality of buckles 61 are connected at a first position to form a track. The guide rail member 7 is provided with a through hole 71, and the first connecting member 3 is used to fix one end of the guide member 2 to the track through the through hole 71. The relative position of the track is as follows: Figure 3 shown.

[0055] In some specific embodiments, the guide rail member 7 includes a hoop 72 and a guide rail body 73, the hoop 72 includes a connecting portion 721 and a tightening portion 722, the connecting portion 721 is fixedly connected to the buckle 61, and the tightening portion 722 is used to sleeve the guide rail body 73 in the hoop 72, wherein the tightening portion 722 is an end of the hoop 72 protruding outward, and the through hole 71 is arranged at the top of the tightening portion 722, such as Figure 5In a specific embodiment, the connecting portion 721 of the hoop 72 can be fixed to the buckle 61 by the connecting bolt 62, and then the first connecting member 3 is passed through the through hole 71 to fix one end of the guide member 2 to the hoop 72, wherein one end of the first connecting member 3 extends into the through hole 71 and is fixed relative to the guide rail body 73. In practical applications, the guide rail body 73 can be a steel rail, and the cross-sectional internal structure of the guide rail body 73 is as shown in FIG. Figure 5 shown.

[0056] In another connection mode between the guide member 2 and the air membrane 1 , an auxiliary member 8 is further included. One end of the auxiliary member 8 is fixedly connected to the first position, and the other end is fixedly connected to the guide member 2 .

[0057] In some specific embodiments, the auxiliary member 8 includes a reinforcing film 81 and an auxiliary film 82. The reinforcing film 81 is fixedly connected to the first position. One end of the auxiliary film 82 is fixedly connected to the reinforcing film 81, and the other end is fixedly connected to the guide member 2 through the first connecting member 3. In practical applications, the auxiliary film 82 can have multiple layers, and the reinforcing film 81 can be fixedly attached to the inner or outer surface of the first position of the air film 1 by welding or welding a reinforcement plate. Figure 7 , the reinforcing film 81 is welded on the inner surface of the air film 1. In a specific embodiment, the air film 1 is a film material composed of a base fabric and a coating, wherein the base fabric is woven with mutually perpendicular wefts and warps, and the reinforcing film 81 is also woven with mutually perpendicular wefts and warps. In the process of welding the reinforcing film 81, the extension direction of the warp and weft of the reinforcing film 81 is consistent with the extension direction of the warp and weft of the air film 1, which can improve the connection strength between the air film 1 and the reinforcing film 81 and the strength of the air film 1 itself, and further prevent the air film 1 from being torn.

[0058] In practical applications, the reinforcement film 81 can be fixedly connected to the inner side of the air film 1, or fixedly connected to the outer side of the air film 1. In one embodiment, the reinforcement film 81 can also be a layer of film fixedly connected to one side of the outer surface of the air film 1 through multiple buckles 61 on the surface of the air film 1, wherein one end of the auxiliary film 82 is fixedly connected to the reinforcement film 81, and the other end is fixedly connected to the guide 2. Thus, the guide 2 can be indirectly connected to the outer surface of the air film 1 to guide the falling snow.

[0059] In some specific embodiments, a fixing member 31 is further included, and there is an overlapping area between the auxiliary film 82 and the guide member 2. The fixing members 31 are respectively located on both sides of the overlapping area. The first connecting member 3 passes through the fixing member 31 in the overlapping area to fix the auxiliary film 82 and the guide member 2 in the overlapping area. Figure 7As shown, at the same time, the edge of the auxiliary film 82 is also provided with a reinforcing edge 22. The reinforcing edge 22 of the auxiliary film 82 and the reinforcing edge 22 of the guide member 2 are respectively located on both sides of the fixing member 31, and the installation of the overlapping area can be further limited and stabilized during use. In a specific embodiment, the fixing member 31 is a fixing plate, and the reinforcing edge 22 is close to one side of the fixing member 31, such as Figure 7 As shown, the protruding portion of the reinforcing edge 22 can provide support for one side of the fixing member 31, increase the friction between the fixing member 31 and the guide member 2, and make the connection between the guide member 2 and the auxiliary film 82 tighter.

[0060] In a specific embodiment, when the guide member 2 is a hard plate material, the guide member 2 can be a curved panel, and the curved panel is convex relative to the connection. In practical applications, the falling snow can slowly slide down along the curved panel, and the buffer space formed by the guide member 2, the air film 1 and the retaining wall 5 can further offset the impact force of the falling snow during the sliding process. When the guide member 2 is a soft film material, no curved convexity will be generated, such as Fig. 9 As shown, the guide member 2 forms a curtain at the connection between the retaining wall 5 and the air film 1, wherein a mounting hole 21 is provided on the film material at a position corresponding to the steel cable 6, and the steel cable 6 passes through the mounting hole 21 and is fixedly connected to the retaining wall 5. A closed buffer space is formed between the curtain, the retaining wall 5 and the air film 1, which can effectively guide the falling of the accumulated snow. In practical applications, the shielding of the connection by the guide member 2 can also provide further optimization effects such as waterproofing and dustproofing for the connection.

[0061] In some specific embodiments, the second connecting member 4 may be a bolt pre-buried in the retaining wall 5, or an expansion bolt and / or a chemical anchor bolt. Figure 8 As shown, it also includes a fastener 41 for pressing the guide member 2 , and the second connecting member 4 passes through the fastener 41 and the mounting hole 21 to fix one end of the guide member 2 on the retaining wall 5 .

[0062] This embodiment provides an air film device with a snowfall guiding device, by covering the connection between the lower outer surface of the air film and the retaining wall with a guide, and a buffer space can be formed between the guide, the air film and the connection to prevent the impact of falling snow. The guide can effectively guide the falling snow to slide from a position away from the connection between the air film and the retaining wall, and can adjust the position where the falling snow slides to the ground, effectively preventing the falling snow from causing damage and destruction to the air film surface in the process of sliding along the air film surface, and can extend the life of the air film device. In rainy and snowy weather, the accumulated snow can be prevented from accumulating close to the retaining wall, which can further simplify the cleaning and sweeping of the accumulated snow.

[0063] The above is a specific description of the preferred implementation of the present application, but the invention of the present application is not limited to the embodiments.
