Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air-supported structures, and particularly to an air-supported structure with a heating and snow removal function. Background Art
[0002] As is well known, an air-supported structure is a building form mainly made of membrane materials and supported by air pressure. It has characteristics such as light weight, firmness, and good climate adaptability, so it has been widely used in fields such as stadiums, greenhouses, and exhibition centers. Since an air-supported structure is mainly supported by air pressure, in the cold snowing season, snow is likely to accumulate on the surface of the air-supported structure, which may cause damage to the structure of the air-supported structure or even failure of its functions. Therefore, the necessity of snow removal for air-supported structures cannot be ignored.
[0003] After retrieval, the patent with the Chinese patent publication number CN207032490U discloses an air-supported structure and an air-supported building with a snow removal function. It is generally described as including a membrane layer, and a track device is also provided on the outer surface of the membrane layer along the arc direction. Two sets of sliding cover plate assemblies are symmetrically arranged on the track device along the width direction of the membrane layer. The two sets of sliding cover plate assemblies can be opened downward or closed upward along the arc direction of the membrane layer. In its use state, when it snows, the sliding cover plate assemblies are closed to receive the snow, and the sliding cover plate assemblies are regularly opened, so that the sliding cover plate assemblies drive the snow to fall together. And a drooping pocket can be formed on one side along the width direction of each membrane layer, and an air supply pipe (not shown in the figure) can be passed through the pocket. The air supply pipe is used to supply hot air to the membrane layer, so that the hot air conveyed by the air supply pipe can heat the membrane layer, and then increase the temperature of the membrane layer, so as to facilitate the rapid melting of the snow on the membrane layer. The patent with the Chinese patent publication number CN215054671U discloses an air-supported snow removal device and an air-supported building. It is generally described as including a snow scraping rod assembly, a sliding mechanism, a first traction device and a second traction device. The sliding mechanism includes a plurality of sliding carts and multiple sets of pulling ropes. The multiple sets of pulling ropes correspond to the plurality of sliding carts one by one. Each set of pulling ropes includes a first pulling rope and a second pulling rope. The upper end of the first pulling rope is connected to the sliding cart, and the other end of the first pulling rope extends along the transverse direction of the air-supported structure to one side. The upper end of the second pulling rope is connected to the sliding cart, and the other end of the second pulling rope extends along the transverse direction of the air-supported structure to the other side. The first traction device is arranged on one side of the transverse direction of the air-supported structure and is connected to the other ends of the respective first pulling ropes. The second traction device is arranged on the other side of the transverse direction of the air-supported structure and is connected to the other ends of the respective second pulling ropes. When in use, the snow scraping rod assembly is used to reciprocate on the top of the air-supported structure to remove the snow on the top of the air-supported structure.
[0004] Although the above-mentioned prior art solutions can assist the air-supported building in reducing snow accumulation and reducing the excessive harm caused by snow accumulation to the air-supported building, the former realizes the auxiliary reception of snowfall through the sliding cover plate assembly and heats the top of the air-supported building by conveying hot air to the film layer to assist in melting the snow accumulation. It is obvious that the addition of the sliding cover plate assembly not only increases the construction cost but also makes the air-supported building lose its original advantages to a certain extent. Moreover, the proportion of snowfall time in winter is also limited, so the cost performance of this measure is relatively low. The latter removes snow by the reciprocating movement of the snow scraping rod assembly on the top of the air-supported building. The main structural material of the air-supported building is the film material. Therefore, during the process of the snow scraping rod assembly being driven to move, on the one hand, it will increase the load on the top of the air-supported building, and on the other hand, it will also accelerate the consumption of the film material, affecting the service life of the air-supported building.

[0023] For the embodiments, please refer to Figures 1 - 14 , a pneumatic film building with a heating and snow removal function, including a film layer 1 of the pneumatic film building, further including an external throwing-off system and an internal heating system.

The power source for throwing off is compressed gas, with better resource utilization rate, richer throwing-off forms, more reasonable structural design, and better practicability.
[0024] It should be further noted that multiple pneumatic linkage components all include inner lining cylinders 16, external threaded column shells 17, primary telescopic ring capsules 18 and secondary telescopic capsule rings 19. Multiple inner lining cylinders 16 are respectively slidably connected in multiple housing cylinders 6. Multiple external threaded column shells 17 are respectively threadedly connected in multiple inner lining cylinders 16.

A communicating pipe 22 is connected between the primary telescopic ring capsule 18 and the secondary telescopic capsule ring 19. A one-way pressure relief valve 23 is installed in the communicating pipe 22. Primary return springs 24 are fixedly connected between the mutually slidable inner lining cylinders 16 and housing cylinders 6. Secondary return springs 25 are fixedly connected between multiple inner lining cylinders 16 and the connecting rings 20 therein. Air supply bent holes 26 are arranged in multiple first connecting cylinders 9. Multiple air supply bent holes 26 are all communicated with guide pipes 27. Multiple guide pipes 27 are respectively communicated with multiple central pipes 5. Multiple central pipes 5 are respectively communicated with multiple primary telescopic ring capsules 18. Multiple secondary telescopic capsule rings 19 are respectively communicated with multiple external threaded column shells 17. Through the design of the pneumatic linkage components, motive power is provided for the rubber hoses 7. When the rubber hoses 7 are in use, the extension and rotational drive of the rubber hoses 7 can be realized. After the rubber hoses 7 are used, it is also convenient to store them in the housing cylinders 6, improving the protection effect of the rubber hoses 7 and enabling the rubber hoses 7 to have a longer service life. Multiple first air supply pipes 28 and second air supply pipes 29 are provided outside multiple installation ropes 2. Multiple first branch pipes 30 are communicated on multiple first air supply pipes 28. Multiple second branch pipes 31 are communicated on multiple second air supply pipes 29. Multiple first branch pipes 30 are respectively rotatably connected with multiple first connecting cylinders 9. Multiple first branch pipes 30 are respectively communicated with multiple air supply bent holes 26. Multiple second branch pipes 31 are respectively fixedly connected with multiple second connecting cylinders 10.

The internal heating system includes multiple heating tapes 8. Multiple heating tapes 8 are all installed in the film layer 1. Multiple film sleeves 36 are sleeved outside multiple heating tapes 8. Multiple film sleeves 36 are all welded to the inside of the film layer 1. Multiple heating tapes 8 are all distributed in a serpentine shape. Through the provision of the internal heating system, the inside of the film layer 1 can be heated, and the temperature of the film layer 1 is increased under the action of heat conduction. When snowflakes fall on the film layer 1, the melting of the snowflakes can be accelerated, promoting the sliding of the snowflakes and alleviating the accumulation of snowflakes on the film layer 1. A protective ring 32 is slidably connected outside the rotating body shell 4.The length of the protective ring 32 is greater than the distance between the rotating body shell 4 and the cover shell cylinder 6 that cooperate with each other. A follow-up reset spring 33 is connected between the protective ring 32 and the rotating body shell 4. The protective ring 32 is fixedly connected with a traction rope 34, and the traction rope 34 is fixedly connected in the mounting seat 3. When the rotating body shell 4 rotates and rises relative to the mounting seat 3, the traction rope 34 will be tightened, thereby forming a pulling effect on the protective ring 32. The protective ring 32 will overcome the follow-up reset spring 33 and move relative to the rotating body shell 4, and then control the gap between the rotating body shell 4 and the cover shell cylinder 6 to be exposed. Each of the plurality of rotating body shells 4 is provided with an outer pushing conical ring surface 35 that matches the rubber hose 7. When the rubber hose 7 is pushed out relative to the cover shell cylinder 6, the outer pushing conical ring surface 35 can form a bending guiding auxiliary push on the rubber hose 7, so that the rubber hose 7 can better cut into the film layer 1, so as to facilitate the subsequent driving and sweeping of the snow on the film layer 1.
[0025] In summary, the working principle of the air-supported building with the function of heating and snow removal is as follows. Before use, the installation of the film layer 1 should be completed relative to the ground surface. During the installation stage of the film layer 1, the heating tape 8 should be installed inside the film layer 1. When installing the heating tape 8, a film sleeve 36 should be sleeved outside the heating tape 8, and the film sleeve 36 should be welded to the inside of the film layer 1 to achieve the relative installation between the heating tape 8 and the film layer 1. Then, the installation ropes 2 should be arranged outside the film layer 1. Since the mounting seat 3 is connected to the installation ropes 2, and both the first air supply pipe 28 and the second air supply pipe 29 are attached to both sides of the installation ropes 2, when the installation ropes 2 are arranged relative to the film layer 1, the synchronous installation of the mounting seat 3, the first air supply pipe 28, and the second air supply pipe 29 relative to the film layer 1 can be achieved. After the installation is completed, the four sides of the film layer 1 should be hermetically connected to the ground surface, and both ends of the installation ropes 2 should also be fixed to the ground surface. A fan pump unit is provided in support of the film layer 1. By operating the fan pump unit, the internal pressure of the film layer 1 can be increased, thereby realizing the unfolding and support of the film layer 1. One end of the first air supply pipe 28 and the second air supply pipe 29 should be blocked, and the other ends of the first air supply pipe 28 and the second air supply pipe 29 should be connected to the fan pump unit. At the same time, a first solenoid valve is provided between the first air supply pipe 28 and the fan pump unit, and a second solenoid valve is provided between the second air supply pipe 29 and the fan pump unit. Through the first solenoid valve, the air supply control of the fan pump unit to the first air supply pipe 28 can be realized, and through the first solenoid valve, the air supply control of the fan pump unit to the second air supply pipe 29 can be realized. A control circuit is installed in support of the heating tape 8. Under normal circumstances, the heating tape 8 is not powered on and does not generate heat. Under normal circumstances, no compressed gas is supplied into the first air supply pipe 28 and the second air supply pipe 29. When no compressed air is pumped into the second air supply pipe 29, under the action of the return spring 13, the threaded cylinder 11 enters the limit insertion state relative to the second connecting cylinder 10. Due to the threaded connection between the threaded cylinder 11 and the second connecting cylinder 10, when the threaded cylinder 11 is inserted relative to the second connecting cylinder 10, it will rotate relative to the second connecting cylinder 10. The rotating threaded cylinder 11 will drive the guide rod 15 to rotate synchronously. The rotating guide rod 15 will drive the first connecting cylinder 9 to rotate. The rotating first connecting cylinder 9 will drive the rotating body shell 4 to rotate. The rotating rotating body shell 4 will cause the cover shell cylinder 6 to rotate and fall into the mounting seat 3, that is, as shown in Figure 1 the state shown. In this state, the towing rope 34 is in a relaxed state. Therefore, under the elastic action of the follow-up return spring 33, the protective ring 32 is pushed and sleeved relative to the cover shell cylinder 6 to block the gap between the cover shell cylinder 6 and the rotating body shell 4.
[0026] Furthermore, since no compressed gas is pumped into the first air supply pipe 28, there is no compressed gas filled in the primary telescopic ring bag 18 and the secondary telescopic ring bag 19, so the primary telescopic ring bag 18 and the secondary telescopic ring bag 19 are both in a compressed state. In this state, the inner liner 16 will be fully inserted relative to the cover tube 6, so that the rubber hose 7 is pulled into the cover tube 6, the primary return spring 24 will also put the primary telescopic ring bag 18 in a compressed state, the external threaded column shell 17 will spirally move to the deepest limit position relative to the inner liner 16, and the secondary return spring 25 will also put the secondary telescopic ring bag 19 in a compressed state In the state, when snow accumulates on the membrane layer 1 due to snowfall, the control circuit of the heating belt 8 is first connected, and then the heating belt 8 is powered on to generate heat, which can promote the increase of the temperature around the membrane layer 1 and accelerate the melting of the snow outside the membrane layer 1. Then, compressed air is pumped into the second air supply pipe 29, and the air entering the second air supply pipe 29 will be divided and guided by multiple second branch pipes 31 and enter the multiple reset elastic bags 14 respectively. Since the multiple reset elastic bags 14 are filled with gas, their own length will increase. Therefore, under the transmission action of the rotating disk 12, the threaded cylinder 11 will be pushed out of the second connecting cylinder 10 During this process, the threaded cylinder 11 will move relative to the second connecting cylinder 10. The moving threaded cylinder 11 will eventually rotate and lift the swivel shell 4 relative to the mounting seat 3 through the transmission of the guide rod 15 and the first connecting cylinder 9. By maintaining the air pressure in the second air supply pipe 29, the swivel shell 4 can be kept in the rotation and lifting state relative to the mounting seat 3. Since the swivel shell 4 will be rotated and lifted relative to the mounting seat 3, the traction rope 34 will enter a straightened state. Therefore, the traction rope 34 in the straightened state will form a traction drive on the protective ring 32, so that the protective ring 32 compresses the follower return spring 33, prompting the protective ring 32 to rotate the swivel. The shielding effect of the gap between the shell 4 and the cover tube 6 fails, and then compressed air is pumped into the first air supply pipe 28. The air entering the first air supply pipe 28 will be diverted and guided by multiple first branch pipes 30 and enter multiple air supply bends 26 respectively. The compressed air entering the air supply bends 26 will be guided by the guide pipe 27 and the center pipe 5 in sequence and finally enter the primary telescopic ring bag 18. After the primary telescopic ring bag 18 is filled with gas, it will produce elastic elongation, so the inner lining tube 16 will be relatively pushed out relative to the cover tube 6. In this process, the rubber hose 7 will also be synchronously pushed out of the cover tube 6.
[0027] Since the one-way pressure relief valve 23 will not allow gas to pass through within a certain pressure range, during the stage when the primary telescopic ring bladder 18 is filled with gas and pushes against the inner liner cylinder 16, no gas will enter the secondary telescopic bladder ring 19. That is, no rotational movement will be formed during the process of the rubber hose 7 extending out of the housing cylinder 6. When the length inside the primary telescopic ring bladder 18 increases to the limit position of the relative movement of the inner liner cylinder 16 with respect to the housing cylinder 6 and gas is continuously pumped into the primary telescopic ring bladder 18, the air pressure inside the primary telescopic ring bladder 18 will reach the pressure relief value of the one-way pressure relief valve 23. At this time, a gas passage will be formed inside the one-way pressure relief valve 23, and the gas inside the primary telescopic ring bladder 18 will enter the secondary telescopic bladder ring 19. After the gas enters the secondary telescopic bladder ring 19, it will cause the secondary telescopic bladder ring 19 to elongate itself. The elongated secondary telescopic bladder ring 19 will push the external thread column shell 17 to move relative to the inner liner cylinder 16 through the connecting ring 20. Due to the threaded connection between the external thread column shell 17 and the inner liner cylinder 16, the relative movement between the external thread column shell 17 and the inner liner cylinder 16 includes the relative rotation of the external thread column shell 17 with respect to the inner liner cylinder 16. Finally, multiple rubber hoses 7 located on the same external thread column shell 17 will form synchronous rotational drive, and the rotating multiple rubber hoses 7 will assist in pushing the snow on the surface of the membrane layer 1 and achieve the throwing away of the snow. Since the inner cross-section of the rubber hose 7 is much smaller than the ventilation cross-section of the one-way pressure relief valve 23, when the one-way pressure relief valve 23 allows gas to pass through, the speed of the gas entering the secondary telescopic bladder ring 19 is much greater than the gas leakage speed. Therefore, the secondary telescopic bladder ring 19 can normally elongate by pumping gas. By controlling the first solenoid valve, the staged pause control of pumping gas into the first gas supply pipe 28 is achieved, so that the air pressure inside the primary telescopic ring bladder 18 first increases to the pressure relief air pressure of the one-way pressure relief valve 23. After the secondary telescopic bladder ring 19 is pushed to the limit length, the pumping of gas into the first gas supply pipe 28 is paused. When the air pressure inside the primary telescopic ring bladder 18 drops to the closing critical point of the one-way pressure relief valve 23, the one-way pressure relief valve 23 closes and no longer allows gas to pass through. In this way, the extended length of the primary telescopic ring bladder 18 can be maintained and no gas is continuously sent into the secondary telescopic bladder ring 19. Since the rubber hose 7 and the secondary telescopic bladder ring 19 are in a mutually connected state, the gas inside the secondary telescopic bladder ring 19 will leak through the rubber hose 7. During the leakage process, the gas inside the secondary telescopic bladder ring 19 decreases, and the secondary telescopic bladder ring 19 contracts again, enabling the external thread column shell 17 to be screwed into the inner liner cylinder 16 relative to the inner liner cylinder 16, prompting the rubber hose 7 to move again. That is, the primary telescopic ring bladder 18 is in a pressure-holding state, and the secondary telescopic bladder ring 19 is in a pressure-relief state. After the gas inside the secondary telescopic bladder ring 19 is completely leaked, gas is pumped into the primary telescopic ring bladder 18 again, so that the air pressure inside the primary telescopic ring bladder 18 can cause the one-way pressure relief valve 23 to enter a connected state, that is, the gas inside the primary telescopic ring bladder 18 enters the secondary telescopic bladder ring 19. This process is repeated,The reciprocating and alternating movement of the external thread column shell 17 relative to the inner lining cylinder 16 is realized, forming the repeated movement of the rubber hose 7, achieving the effect of continuously removing snow from the film layer 1. In actual situations, due to solely relying on the heating of the heat tracing belt 8 to promote the melting of the snow outside the film layer 1, the efficiency is relatively low. And considering the reason of the day-night temperature difference, there will also be a phenomenon that the snow freezes again after melting. Such a phenomenon will cause the un-melted snow to form a tighter adhesion with the film layer 1, increasing the difficulty of snow removal. When solely driving the snow on the film layer 1 through the rubber hose 7, since the snow is solid ice crystal particles, the hard and irregularly shaped particles are likely to form scratches on the film layer 1. While heating through the heat tracing belt 8 will promote the melting of the bottom of the snow on the film layer 1, and the melted water will improve the relative sliding effect between the snow and the film layer 1, that is, the melted water will play a lubricating role, making it easier for the snow to be driven away relative to the film layer 1. Even the part of the un-melted snow in contact with the film layer 1 will be affected by the temperature rise, resulting in a decrease in hardness. In this state, when pushing the snow relative to the film layer 1, the sliding damage of the moving snow to the film layer 1 is reduced. And the gas discharged outside the rubber hose 7 will also assist in blowing the snow, indirectly improving the snow removal effect.
