Description

Technical Field

[0001] The present invention relates to the technical field of air-film buildings, and in particular to an air-film building with heating and snow-removing functions. Background Art

[0002] As we all know, air-supported buildings are a type of building that uses membrane materials as the main structural material and is supported by air pressure. It has the characteristics of being light, strong and climatically adaptable, and has therefore been widely used in stadiums, greenhouses and exhibition centers. Since air-supported buildings are mainly supported by air pressure, snow easily accumulates on their surface during cold snowy seasons, which may cause structural damage or even functional failure of the buildings. Therefore, the necessity of snow removal in air-supported buildings cannot be ignored.

[0003] After searching, the Chinese patent publication number CN207032490U discloses an air-supported building structure and an air-supported building with a snow removal function, which is roughly described as including a membrane layer, and a track device is provided on the outer surface of the membrane layer along the arc direction, and two groups of sliding cover assemblies are symmetrically provided on the track device along the width direction of the membrane layer, and the two groups of sliding cover assemblies can be opened downward or closed upward along the arc direction of the membrane layer. When it snows, the sliding cover assembly is closed to receive the accumulated snow, and the sliding cover assembly is opened periodically so that the sliding cover assembly brings the accumulated snow down together, and a drooping bag can be formed along one side of the width direction of each membrane layer, and an air supply pipe (not shown in the figure) can be passed through the bag, and the air supply pipe is used to transport hot air to the membrane layer, so that the hot air transported by the air supply pipe can heat the membrane layer, thereby increasing the temperature of the membrane layer, which is beneficial to the accumulation of snow on the membrane layer. Quick melting, the Chinese patent publication number CN215054671U discloses an air film snow removal device and an air film building, which is roughly described as including a snow scraper rod assembly, a sliding mechanism, a first traction device and a second traction device. The sliding mechanism includes multiple sliding vehicles and multiple groups of pull ropes. The multiple groups of pull ropes correspond to the multiple sliding vehicles one by one. Each group of pull ropes includes a first pull rope and a second pull rope. The upper end of the first pull rope is connected to the sliding vehicle, and the other end of the first pull rope extends to one side along the transverse direction of the air film. The upper end of the second pull rope is connected to the sliding vehicle, and the other end of the second pull rope extends to the other side along the transverse direction of the air film. The first traction device is arranged on one side of the transverse direction of the air film and is connected to the other end of each first pull rope. The second traction device is arranged on the other side of the transverse direction of the air film and is connected to the other end of each second pull rope. When in use, the snow scraper rod assembly is used to reciprocate on the top of the air film to remove the snow on the top of the air film.

[0004] Although the above-mentioned existing technical solutions can assist air-supported buildings in reducing snow accumulation and reduce the excessive damage caused by snow accumulation to air-supported buildings, the former is to assist in receiving snowfall through a sliding cover assembly, and to heat the top of the air-supported building by delivering hot air to the membrane layer to assist in melting the accumulated snow. It can be obviously judged that the addition of a sliding cover 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-effectiveness of this measure is low. The latter is to remove snow through a reciprocating motion of a snow scraper assembly on the top of the air membrane. The main structural material of the air-supported building itself is membrane material. Therefore, when the snow scraper assembly is pulled and moved, on the one hand, it will cause the load on the top of the air-supported building to increase, and on the other hand, it will accelerate the consumption of the membrane material, affecting the service life of the air-supported building.

DETAILED DESCRIPTION

The multiple first connecting tubes 9 are all fixedly connected with guide rods 15, and the multiple threaded tubes 11 are respectively slidably connected with the multiple guide rods 15. Through the design of the air pressure lifting component, a structure for driving and lifting the swivel shell 4 in the external ejection system is provided, so that the external ejection system can be used after the mounting seat 3 is raised, and it is also convenient for the external ejection system to be stored relative to the mounting seat 3 after use.

The core tubes 5 are all fixedly connected to the cover tubes 6, and pneumatic linkage components are installed in the multiple cover tubes 6. The multiple pneumatic linkage components are all connected to multiple rubber hoses 7. By injecting compressed gas into the pneumatic linkage components, the rubber hoses 7 can be extended and driven to move. Through the design of the external throwing system, the snowflakes landing on the membrane layer 1 are actively driven and thrown away to avoid the accumulation of snowflakes outside the membrane layer 1. The air film building is used to perform snow removal operations. The power source for throwing is compressed gas, which has better resource utilization, richer throwing forms, more reasonable structural design, and better practicality.

[0038] It should be further explained that the multiple pneumatic linkage components include an inner liner 16, an outer threaded cylindrical shell 17, a primary telescopic ring capsule 18 and a secondary telescopic capsule ring 19. The multiple inner liners 16 are respectively slidably connected to the multiple cover tubes 6, the multiple outer threaded cylindrical shells 17 are respectively threadedly connected to the multiple inner liners 16, the multiple primary telescopic ring capsules 18 are respectively fixedly connected to the multiple cover tubes 6, the multiple primary telescopic ring capsules 18 are respectively fixedly connected to the multiple inner liners 16, the multiple secondary telescopic capsule rings 19 are respectively fixedly connected to the multiple inner liners 16, the multiple secondary telescopic capsule rings 19 are all fixedly connected to the connecting rings 20, the multiple connecting rings 20 are respectively rotatably connected to the multiple outer threaded cylindrical shells 17, and the multiple outer threaded cylindrical shells 17 are all fixedly connected to the multiple quick-connect pipes 21 , multiple rubber hoses 7 are respectively connected to multiple quick-connect pipes 21, a connecting pipe 22 is connected between the primary telescopic ring bag 18 and the secondary telescopic bag ring 19, a one-way pressure relief valve 23 is installed in the connecting pipe 22, the inner liner 16 and the cover tube 6 that are slidably connected to each other are fixedly connected with a primary return spring 24, multiple inner liners 16 and the connecting ring 20 therein are fixedly connected with a secondary return spring 25, multiple first connecting tubes 9 are provided with air supply bends 26, multiple air supply bends 26 are connected with guide pipes 27, multiple guide pipes 27 are respectively connected with multiple center tubes 5, multiple center tubes 5 are respectively connected with multiple primary telescopic ring bags 18, multiple secondary telescopic bag rings 19 are respectively connected with multiple external threaded cylindrical shells 17, through the design of the pneumatic linkage component, Provide movement power for the rubber hose 7. When the rubber hose 7 is in use, the rubber hose 7 can be extended and rotated. After the rubber hose 7 is used, it is also convenient to store it in the cover tube 6, thereby improving the protection effect of the rubber hose 7 and making the rubber hose 7 have a longer service life. Multiple installation ropes 2 are equipped with a first air supply pipe 28 and a second air supply pipe 29. Multiple first air supply pipes 28 are connected to multiple first branch pipes 30, and multiple second air supply pipes 29 are connected to multiple second branch pipes 31. Multiple first branch pipes 30 are respectively rotatably connected to multiple first connecting tubes 9, and multiple first branch pipes 30 are respectively connected to multiple air supply bends 26. Multiple second branch pipes 31 are respectively fixedly connected to multiple second connecting tubes 10. The branch pipes 31 are respectively connected to multiple reset elastic bags 14, which is convenient for synchronously feeding compressed air into multiple air supply bends 26, and also convenient for synchronously feeding compressed air into multiple reset elastic bags 14. The internal heating system includes multiple heating belts 8, and the multiple heating belts 8 are all installed in the membrane layer 1. The multiple heating belts 8 are all covered with membrane sleeves 36. The multiple membrane sleeves 36 are all welded to the inside of the membrane layer 1. The multiple heating belts 8 are all distributed in a serpentine manner. Through the equipment of the internal heating system, the inside of the membrane layer 1 can be heated, and the temperature of the membrane layer 1 can be increased under the action of heat conduction. When snowflakes fall on the membrane layer 1, the melting of snowflakes can be accelerated, the sliding of snowflakes can be promoted, and the accumulation of snowflakes on the membrane layer 1 can be alleviated. The outer sliding connection of the swivel shell 4 is provided with a protective ring 32.The length of the protective ring 32 is greater than the distance between the mutually fitting swivel shell 4 and the cover shell tube 6. A follower return spring 33 is connected between the protective ring 32 and the swivel shell 4. The protective ring 32 is fixedly connected to a traction rope 34. The traction rope 34 is fixedly connected to the mounting seat 3. When the swivel 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 follower return spring 33 to form a movement relative to the swivel shell 4, thereby controlling the gap between the swivel shell 4 and the cover shell tube 6 to be exposed. Multiple swivel shells 4 are all provided with an outward-pushing conical ring surface 35 that matches the rubber hose 7. When the rubber hose 7 is pushed out relative to the cover shell tube 6, the outward-pushing conical ring surface 35 can form a bending guide auxiliary push for the rubber hose 7, so that the rubber hose 7 can better cut into the membrane layer 1, so as to facilitate the subsequent driving and sweeping of the snow accumulated on the membrane layer 1.

[0039] In summary, the working principle of the air-film building with heating and snow removal function is that before use, the membrane layer 1 needs to be installed relative to the ground surface. During the installation stage of the membrane layer 1, the heating tape 8 should be installed in the membrane layer 1. When the heating tape 8 is installed, a membrane sleeve 36 is set on the outside of the heating tape 8, and the membrane sleeve 36 is welded to the inside of the membrane layer 1 to achieve relative installation between the heating tape 8 and the membrane layer 1. Then, the installation rope 2 is laid outside the membrane layer 1. Since the mounting seat 3 is connected to the installation rope 2, and the first air supply pipe 28 and the second air supply pipe 29 are attached to both sides of the installation rope 2 Therefore, when the installation rope 2 is arranged relative to the membrane layer 1, the installation of the mounting seat 3, the first air supply pipe 28 and the second air supply pipe 29 can be realized synchronously with respect to the membrane layer 1. After the installation is completed, the four sides of the membrane layer 1 should be closed and connected to the ground surface, and the two ends of the installation rope 2 should also be fixed to the ground surface. The supporting membrane layer 1 is provided with a fan pump group. The internal pressurization of the membrane layer 1 can be realized by running the fan pump group, thereby realizing the expansion and support of the membrane layer 1. One end of the first air supply pipe 28 and the second air supply pipe 29 is blocked, and the other ends of the first air supply pipe 28 and the second air supply pipe 29 are connected to the fan. In the machine pump group, a first solenoid valve is provided between the first air supply pipe 28 and the fan pump group, and a second solenoid valve is provided between the second air supply pipe 29 and the fan pump group. The first solenoid valve can realize the air supply control of the fan pump group to the first air supply pipe 28, and the first solenoid valve can realize the air supply control of the fan pump group to the second air supply pipe 29. A control circuit is installed for the heating belt 8. Under normal circumstances, the heating belt 8 is not powered and does not generate heat. Under normal circumstances, compressed gas is not supplied to the first air supply pipe 28 and the second air supply pipe 29, and there is no compressed gas in the second air supply pipe 29. When air is pumped in, the threaded cylinder 11 enters the extreme insertion state relative to the second connecting cylinder 10 under the action of the return tension spring 13. Due to the threaded connection between the threaded cylinder 11 and the second connecting cylinder 10, the threaded cylinder 11 is inserted relative to the second connecting cylinder 10 and rotates relative to the second connecting cylinder 10. The rotating threaded cylinder 11 drives the guide rod 15 to rotate synchronously. The rotation of the guide rod 15 drives the first connecting cylinder 9 to rotate. The rotation of the first connecting cylinder 9 drives the swivel shell 4 to rotate. The rotation of the swivel shell 4 causes the cover cylinder 6 to rotate and fall into the mounting seat 3, as shown in the attached Figure 1 In the state shown, the traction rope 34 is in a relaxed state, so the protective ring 32 is pushed by the elastic action of the follower return spring 33 and is inserted relative to the cover tube 6 to block the gap between the cover tube 6 and the swivel shell 4.

[0040] 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. Therefore, 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, and 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 this state, when snow accumulates on the membrane layer 1 due to snowfall, the control circuit of the heating tape 8 is first connected, and then the heating tape 8 is energized 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. The air entering the second air supply pipe 29 will be diverted 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, causing the protective ring 32 to compress the follower return spring 33, prompting the protective ring 32 to rotate the swivel shell 4 relative to the mounting seat 3. 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. Since 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 in sequence by the guide pipe 27 and the center pipe 5 and finally enter the primary telescopic ring bag 18. Since the primary telescopic ring bag 18 will produce elastic extension after being filled with gas, the inner lining tube 16 will be pushed out relative to the cover tube 6. During this process, the rubber hose 7 will also be synchronously pushed out of the cover tube 6.

[0041] Since the one-way pressure relief valve 23 will not allow gas to pass through within a certain pressure range, no gas will enter the secondary telescopic bag ring 19 when the primary telescopic ring bag 18 is filled with gas and pushes the inner liner 16, that is, no rotational movement will be formed in the process of the rubber hose 7 extending out of the cover tube 6. When the length of the primary telescopic ring bag 18 increases to the limit position of the movement of the inner liner 16 relative to the cover tube 6, continuing to pump gas into the primary telescopic ring bag 18 will make the air pressure in the primary telescopic ring bag 18 reach the pressure relief value of the one-way pressure relief valve 23. At this time, a gas channel is formed inside the one-way pressure relief valve 23, and the gas in the primary telescopic ring bag 18 will enter the secondary telescopic bag ring 19. After the gas enters the secondary telescopic bag ring 19, it will prompt the secondary The self-elongation of the secondary telescopic bag ring 19 and the elongated secondary telescopic bag ring 19 will push the external threaded cylindrical shell 17 to move relative to the inner liner 16 through the connecting ring 20. Due to the threaded connection between the external threaded cylindrical shell 17 and the inner liner 16, the relative movement between the external threaded cylindrical shell 17 and the inner liner 16 includes the relative rotation between the external threaded cylindrical shell 17 and the inner liner 16, and finally the multiple rubber hoses 7 located on the same external threaded cylindrical shell 17 are driven synchronously. The multiple rotating rubber hoses 7 will assist in pushing the snow on the surface of the membrane layer 1 and realize 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 gas entering the secondary telescopic bag ring 19 is much greater than the leakage speed of gas, so the secondary telescopic bag ring 19 can be normally extended by pumping in gas, and the staged suspension control of pumping gas into the first air supply pipe 28 is realized by controlling the first solenoid valve, so that the air pressure in the primary telescopic ring bag 18 is first increased to the pressure relief pressure of the one-way pressure relief valve 23, and after the secondary telescopic bag ring 19 is pushed to the limit length, the pumping of gas into the first air supply pipe 28 is suspended. When the air pressure in the primary telescopic ring bag 18 is reduced to the closing critical point of the one-way pressure relief valve 23, the one-way pressure relief valve 23 is closed and no longer allows gas to pass through, so that the extension length of the primary telescopic ring bag 18 can be maintained and gas will not be continuously supplied to the secondary telescopic bag ring 19. The contraction capsule rings 19 are in a state of interconnection, so the gas in the secondary telescopic capsule ring 19 will leak through the rubber hose 7. During the leakage process, the gas in the secondary telescopic capsule ring 19 is reduced, and the secondary telescopic capsule ring 19 contracts again, which can make the external threaded cylindrical shell 17 spirally retract relative to the inner liner 16, prompting the rubber hose 7 to move again, that is, the primary telescopic ring capsule 18 is in a pressure-maintaining state, and the secondary telescopic capsule ring 19 is in a pressure-relieving state. After the gas in the secondary telescopic capsule ring 19 is completely leaked, gas is pumped into the primary telescopic ring capsule 18 again, so that the air pressure in the primary telescopic ring capsule 18 can prompt the one-way pressure relief valve 23 to enter a connected state, that is, the gas in the primary telescopic ring capsule 18 enters the secondary telescopic ring capsule 19, and this is repeated.The reciprocating alternating motion of the external threaded cylindrical shell 17 relative to the inner liner 16 is realized to form a repeated motion of the rubber hose 7, so as to achieve the effect of continuous snow removal on the membrane layer 1. In actual circumstances, the efficiency of melting the snow outside the membrane layer 1 is low due to the simple reliance on the heating belt 8 for heating. In addition, considering the temperature difference between day and night, the snow may freeze again after melting. Such a phenomenon will form a tighter adhesion between the unmelted snow and the membrane layer 1, making it more difficult to remove the snow. When the snow on the membrane layer 1 is simply driven by the rubber hose 7, the snow is hard and irregular in shape because it is solid ice crystal particles. The particles can easily scratch the membrane 1. The heating by the heating cable 8 causes the bottom of the snow on the membrane 1 to melt. The melted water then increases the relative sliding between the snow and the membrane 1, acting as a lubricant, making it easier for the snow to move away from the membrane 1. Even the unmelted snow in contact with the membrane 1 will be affected by the increased temperature, causing its hardness to decrease. In this state, the snow is pushed against the membrane 1, reducing the sliding damage caused by the moving snow to the membrane 1. Furthermore, the gas discharged through the rubber hose 7 also assists in blowing the snow, indirectly improving the snow removal effect.
