Description

Technical Field

[0001] This utility model relates to the field of inflatable membrane building technology, and in particular to a low-temperature resistant inflatable membrane exhibition hall with photovoltaic power generation function. Background Technology

[0002] An inflatable membrane structure is made of polymer membrane materials (such as PVC and ETFE). Common inflatable membrane buildings consist of an inflatable membrane forming the outer wall. The edges of the inflatable membrane are fixed to the foundation by clamping devices. By continuously inflating the membrane, a stable spatial structure is formed without the need for internal beams and columns. Inflatable membrane buildings are also often equipped with ropes to limit the outward tension of the inflatable membrane and prevent it from constantly inflating and causing the clamping points to loosen. This type of building is suitable for low-cost, rapid construction scenarios that require ultra-large spaces. Since exhibition halls often require large spaces, with the rapid development of inflatable membrane materials in the construction field, it has become possible to quickly construct ultra-large exhibition halls, making the exhibition and preparation of exhibition halls more convenient and faster. They can be quickly assembled, constructed, and disassembled in various locations.

[0003] However, existing inflatable membrane exhibition halls require additional cables and power swapping equipment during construction. Once these devices are used, they are difficult to reuse, resulting in equipment being idle and increased construction costs. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a low-temperature resistant inflatable membrane exhibition hall with photovoltaic power generation function.

[0005] This utility model provides a low-temperature resistant inflatable membrane exhibition hall with photovoltaic power generation function, comprising:

[0006] According to the technical solutions provided in the embodiments of this application,

[0007] According to the technical solutions provided in the embodiments of this application,

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This invention incorporates solar panels. A motor-driven rope guide wheel, under friction, moves the mounting base along the rope, ensuring the solar panels on the base always face sunlight, converting light energy into electrical energy and ensuring high light absorption efficiency. Lightweight rollers are placed between the rope and the inflatable membrane to ensure stable movement, preventing scratches or damage to the membrane's outer surface and maintaining stable air pressure inside and outside the exhibition hall. The energy generated by the solar panels reduces or eliminates the need for cables and other equipment, lowering the demand for electrical equipment and using clean energy, aligning with eco-friendly principles. After the exhibition hall is dismantled, the solar panels can be reused, increasing equipment utilization and reducing construction costs. Furthermore, a labeling layer and light-transmitting holes are included. Since light shines on different positions on the labeling layer at different times, time markings are added to the labeling layer for easy timekeeping by personnel inside the exhibition hall. Finally, the telescopic mechanism allows the four corners of the solar panels to tilt upwards or downwards, facilitating fine-tuning of the panel's angle and maximizing sunlight absorption.

[0010] This invention also includes a cleaning component. When the mounting base moves to the east and west sides of the inflatable membrane, the mounting base pushes the switch column downwards, causing the second sealing plate to move downwards. The gas inside the inflatable membrane enters the gas storage chamber, then enters the elongated channel through the first opening, and finally exits from the vent, thus cleaning the surface of the solar panel and preventing dust from contaminating the solar panel surface, which could reduce the light energy reception efficiency. Furthermore, a first sealing plate, a return spring, and a fixing cylinder are provided. On the one hand, they serve a sealing function to prevent gas from flowing out from the gap between the switch column and the clamping member. On the other hand, they serve a resetting function. When the mounting base is removed after cleaning, the return spring causes the first and second sealing plates to reset, achieving a continuous and effective sealing effect. Furthermore, to prevent the second sealing plate from becoming misaligned after repeated movement, a guide rod, a guide plate, and a vent are provided at the top of the second sealing plate to ensure that the second sealing plate always moves vertically up and down, ensuring the stability of the second sealing plate position and a stable sealing effect.

It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0023] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Please refer to Figures 1-5An embodiment of this utility model provides a low-temperature resistant inflatable membrane exhibition hall with photovoltaic power generation function, comprising:

[0025] The main body of the exhibition hall 1 includes a foundation 12, on which an inflatable membrane 11 is provided. The top edge of the inflatable membrane 11 is provided with a clamping member 13 connected to the foundation 12. The axis of the middle part of the inflatable membrane 11 extends in a north-south direction. Ropes 15 arranged in a north-south direction are provided in the middle part of the inflatable membrane 11. The two ends of the ropes 15 are respectively connected to the top of the clamping member 13. Rope end fixing members 14 are provided on the clamping member 13. The ends of the ropes 15 are connected to the rope end fixing members 14. Optionally, the rope end fixing members 14 are hooks. In addition, a fan 16 is provided at the south or north end of the inflatable membrane 11 to fill the inflatable membrane 11 with gas, increase the air pressure inside the inflatable membrane 11, and ensure that the inflatable membrane 11 inflates.

[0026] The solar module 2 includes a mounting base 21 located on the outer side of the middle of the inflatable membrane 11. The mounting base 21 has a plurality of solar panels 22 at the end away from the inflatable membrane 11, and a plurality of lightweight rollers 27 attached to the outer surface of the inflatable membrane 11 at the other end. The axis of each lightweight roller 27 extends in the north-south direction. The solar module 2 also includes a drive unit located between the lightweight rollers 27 and the mounting base 21. The drive unit is used to drive the mounting base 21 to move along the rope 15.

[0027] like Figure 1 and Figure 2 As shown, the mounting base 21 is driven by the drive unit to move along the rope 15, causing the solar panel 22 to move along the central surface of the inflatable membrane 11. Since the axis of the central part of the inflatable membrane 11 extends in the north-south direction, the solar panel 22 will move in the east-west direction, ensuring that light always shines on the solar panel 22, thereby converting light energy into electrical energy and ensuring high light energy absorption efficiency. A lightweight roller 27 is set between the rope 15 and the inflatable membrane 11 to ensure the stability of the movement, avoid scratching or damaging the outer surface of the inflatable membrane 11, and ensure that the air pressure inside and outside the inflatable membrane 11 remains stable. The energy generated by the solar module 2 can reduce or eliminate the installation of cables and other equipment, which not only reduces the demand for electrical equipment, but also uses clean energy, which is in line with the concept of ecological and environmental protection. Furthermore, after the exhibition hall is dismantled, the solar module 2 can be removed and reused, improving equipment utilization and reducing construction costs.

[0028] In some embodiments, the solar module 2 further includes a power module 211 disposed on one side of the inflatable membrane 11 along the north-south direction. The input terminal of the power module 211 is connected to the output terminal of each solar panel 22, and the output terminal of the power module 211 is connected to the input terminal of electrical equipment in the exhibition hall. Figure 1As shown, the power module 211 is located at the south or north end of the inflatable membrane 11. When the solar panel 22 moves back and forth in the east-west direction, the cable connecting the solar panel 22 and the power module 211 will sway along with it, and the cable will not be tangled. In addition, the power module 211 is existing technology and consists of an inverter, a battery and a controller, etc., to ensure the storage and output of electrical energy.

[0029] In some embodiments, telescopic members 212 are provided at the four corners of the bottom end of the solar panel 22, and the ends of the telescopic members 212 away from the solar panel 22 are connected to the mounting substrate 21; for example Figure 3 As shown, the telescopic component 212 can be used to tilt the four corners of the solar panel 22 up or down, making it easy to fine-tune the tilt angle of the solar panel 22 and receive more light energy. Optionally, the telescopic component 212 is a miniature electric push rod, whose input end is electrically connected to the output end of the power module 211 to ensure the stable operation of the telescopic component 212.

[0030] In some embodiments, the bottom end of the mounting base plate 21 is provided with a partition plate 23 corresponding to one side of each rope 15, and a fixed shaft 26 is provided between each partition plate 23. A lightweight roller 27 is rotatably mounted in the middle of each fixed shaft 26. The driving part includes a motor 24 provided on the partition plate 23. The output shaft of the motor 24 passes through the partition plate 23 and is fitted with a rope guide wheel 25. The fixed shaft 26 located on both sides of the rope guide wheel 25 is provided with a limiting groove 28 corresponding to the rope guide wheel 25.

[0031] like Figure 3 and Figure 4 As shown, the rope 15 is represented by a dashed line. It is located above each fixed shaft 26 and below the rope guide wheel 25. The motor 24 drives the rope guide wheel 25 to rotate. Through friction, the mounting base plate 21 moves along the rope 15. The limiting groove 28 provided on this basis causes the rope guide wheel 25 to press down on the rope 15, improving the stability of the rope 15 and preventing the mounting base plate 21 from moving in the north-south direction.

[0032] In some embodiments, a light-transmitting hole 29 is provided in the middle of the mounting substrate 21, and the light-transmitting hole 29 extends in a north-south direction. Each lightweight roller 27 and each solar panel 22 are divided into two groups and located on both sides of the light-transmitting hole 29. A marking layer 210 is provided at the top of the foundation 12, and time scale lines are provided on the marking layer 210 along an east-west direction. Figure 1 and Figure 2 As shown, since each lightweight roller 27 and each solar panel 22 are divided into two groups on both sides of the light-passing hole 29, they will not block the light passing through the light-passing hole 29. The light passes through the light-passing hole 29 at different times and shines on the marking layer 210 at different positions. Therefore, time scale lines are set on the marking layer 210 to make it easier for people in the exhibition hall to understand the time.

[0033] In some embodiments, the clamping member 13 is provided with cleaning components 3 on both sides along the east-west direction. The cleaning components 3 are used to form an airflow to sweep the surface of the solar panel 22. By cleaning the dust and debris on the surface of the solar panel 22, the situation where the light energy absorption efficiency of the solar panel 22 is reduced due to the obstruction of dust and debris is avoided. In addition, the two cleaning components 3 are respectively set on the east and west sides of the inflatable film 11 to facilitate the cleaning of the two sets of solar panels 22 separately and ensure cleaning efficiency.

[0034] In some embodiments, the cleaning component 3 includes:

[0035] The air storage chamber 314 is located on the side of the clamping member 13 along the east-west direction and communicates with the interior of the air-filled membrane 11;

[0036] The elongated channel 35 has a first opening at the bottom that communicates with the air storage chamber 314, and an air outlet 36 at the top that faces the air inflatable membrane 11.

[0037] The switching unit includes a second sealing plate 37 that can seal the first opening, and a plurality of switching posts 32 disposed between the flat elongated channel 35 and the inflatable membrane 11. The bottom end of the switching post 32 is connected to the bottom end of the second sealing plate 37. When the mounting base plate 21 pushes the switching post 32 downward, the second sealing plate 37 releases the seal on the first opening.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, when the mounting base plate 21 moves to the easternmost and westernmost sides, the mounting base plate 21 pushes the switch post 32 downwards, the second sealing plate 37 releases the seal on the first opening, the gas inside the inflation membrane 11 flows into the gas storage chamber 314, enters the flat elongated channel 35 through the first opening, and finally sprays out from the air outlet 36, thus achieving the purpose of cleaning the surface of the solar panel 22.

[0039] In some embodiments, the switch post 32 is slidably inserted into the top of the clamping member 13 in the vertical direction. The gas storage chamber 314 is provided with a fixing cylinder 31 corresponding to the position of each switch post 32. The bottom end of each switch post 32 is provided with a first sealing plate 33 that can seal the lower opening of the fixing cylinder 31. The first sealing plate 33 and the second sealing plate 37 are connected by a linkage rod 38. The top end of the first sealing plate 33 is provided with a return spring 34. The top end of the return spring 34 is connected to the inner wall of the gas storage chamber 314.

[0040] like Figure 1 , Figure 2 and Figure 5As shown, the mounting base plate 21 pushes the switch post 32 downward, the reset spring 34 deforms and lengthens, and drives the first sealing plate 33, the linkage rod 38 and the second sealing plate 37 downward, releasing the closure of the first opening, so that the airflow can stably enter the interior of the flat elongated channel 35. After the mounting base plate 21 is separated from the switch post 32, under the action of the reset spring 34, the first sealing plate 33 is reset and seals the lower opening of the fixed cylinder 31, and the second sealing plate 37 is reset and seals the first opening of the flat elongated channel 35, preventing the gas inside the gas storage chamber 314 from overflowing outward, and preventing the unstable pressure inside and outside the inflation membrane 11 caused by gas overflow. Furthermore, the flat elongated channel 35 extends in the north-south direction, the second sealing plate 37 is long and narrow, and multiple switch posts 32 are arranged in the north-south direction. Thus, each switch post 32 corresponds to a reset spring 34, ensuring that the second sealing plate 37 can be stably moved.

[0041] In some embodiments, the second sealing plate 37 is provided with a guide rod 39 at its top end, and a guide plate 310 is provided at the top end of the guide rod 39. The side surface of the guide plate 310 fits the inner surface of the flat elongated channel 35, and a plurality of vent holes 311 are uniformly provided on the guide plate 310.

[0042] like Figure 1 , Figure 2 and Figure 5 As shown, when the second sealing plate 37 moves downward, the side surface of the guide plate 310 fits with the inner surface of the elongated channel 35, ensuring the stable vertical movement of the second sealing plate 37 and preventing the second sealing plate 37 from deviating in position and failing to seal the first opening. In addition, the vent hole 311 ensures smooth airflow inside the elongated channel 35 and prevents the guide plate 310 from causing airflow blockage.

[0043] In some embodiments, an externally threaded cylinder 312 is threadedly installed between the clamping member 13 and the inflatable membrane 11, and a sealing ring plate 313 is provided at the end of the externally threaded cylinder 312 away from the clamping member 13; for example Figure 5 As shown, the external threaded cylinder 312 is connected to the pressure member 13 through the inflatable membrane 11 by the thread, so that the sealing ring plate 313 presses the inflatable membrane 11 against the side surface of the pressure member 13 to prevent airflow from leaking from the connection.
