Description

Technical Field

[0001] This utility model relates to the field of inflatable device technology, and in particular to an inflatable device for assembling air-supported membrane structures. Background Technology

[0002] An air-supported membrane structure refers to a building structure system that uses special architectural membrane materials as its outer shell and is equipped with a set of intelligent electromechanical equipment to provide positive air pressure inside the air-supported membrane structure to support the main body of the building. When the air-supported membrane structure is inflated, it needs to use air-inflating equipment to blow air into the structure and make the membrane expand. By properly adjusting the air pressure inside the membrane structure, it can resist wind and other external forces.

[0003] In the prior art, a combined inflatable device for air-supported membrane structures, disclosed in CN216894998U, includes a housing and a support frame mounted on the lower surface of the housing. Two sets of protective frames are installed on the inner bottom wall of the housing. A main fan, fixed to the inner wall of the housing, is located inside the front protective frame, while a backup fan, fixed to the inner wall of the housing, is located inside the rear protective frame. This combined inflatable device for air-supported membrane structures achieves its function through the main fan, enabling the intake of external air into the air-supported membrane structure, thus improving its practicality. The backup fan provides protection; if the main fan fails, the backup fan can take over, maintaining the pressure of the air-supported membrane structure and preventing collapse, further enhancing its practicality.

[0004] In the aforementioned device, the air outlet pipe between the blower body and the housing lacks guide pipes or other devices, and the bottom of the housing is equipped with a return air grille. In actual use, the air blown out by the blower first accumulates inside the housing and cannot be directly introduced into the air-supported membrane structure. Furthermore, the accumulated air may be discharged from the return air grille, making it impossible to pressurize the air-supported membrane structure. The aforementioned device has certain deficiencies in pressurizing the air-supported membrane structure, such as the inability to adjust the air volume ratio and the inability to control the blower load and voltage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an air-inflating device for assembling air-supported membrane structures, which has the advantages of fluid acceleration and compact, adaptable structure, thus solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: an air-supported membrane building assembly inflation device, comprising a box body, wherein protective frames are symmetrically fixedly installed inside the box body, and centrifugal fans are fixedly installed inside each of the protective frames. There are two centrifugal fans, one of which is a main fan and the other is a backup fan. One side of the box body is provided with heat dissipation holes evenly arranged in a linear array on one side of the protective frame. A rectangular groove is provided on the top of the box body, and an energy storage power supply is movably installed inside the rectangular groove. The bottom of the energy storage power supply is located above the protective frame. Inverters are fixedly installed inside both sides of the box body diagonally above the protective frame. The frequency converters are electrically connected to the centrifugal fans. A Venturi tube is fixedly connected to the output end of the centrifugal fan.

[0007] With the above structural setup, the cooperation between the centrifugal fan and the venturi tube can accelerate air circulation and introduce more air through the riser, thereby blowing more air into the air-supported structure. Two centrifugal fans are set up, one as the main fan and the other as the backup fan.

[0008] Preferably, the centrifugal fan includes a fan body, an air inlet pipe on one side of the fan body, the air inlet pipe communicating with the outside of the housing, an air outlet pipe on the top of the centrifugal fan, and the air outlet pipes of the two fans are connected to each other.

[0009] With the above structural design, the centrifugal fan is fixedly installed inside the protective frame. The protective frame can protect the centrifugal fan and make it easier to fix the centrifugal fan in place during installation.

[0010] Preferably, the energy storage power supply has symmetrical support legs on both sides of its bottom, with the bottom of the support legs located above the protective frame, and handles are symmetrically fixedly installed on the top of the energy storage power supply.

[0011] With the above structural design, the energy storage power supply can quickly dissipate the heat generated during operation. The heat can be discharged from the inside of the enclosure through the heat dissipation holes, achieving a heat dissipation effect. The energy storage power supply can be quickly placed into or removed from the inside of the enclosure by lifting it, achieving rapid installation.

[0012] Preferably, the venturi tube is connected to the air outlet tube. The venturi tube includes a receiving section, a throat section, a diffuser section, and a riser. The receiving section is connected to the air outlet tube. The diffuser section is installed on the side wall of the housing. The throat section is located between the receiving section and the diffuser section. The receiving section, the throat section, and the diffuser section are connected. A riser is provided at the top of the throat section, and the end of the riser extends outside the housing.

[0013] With the above structural design, when air passes through the throat section, it can accelerate the flow of air inside the riser, and then diffuse and discharge through the diffuser section, thereby accelerating air circulation while blowing more air into the air-supported structure.

[0014] This utility model has the following advantages:

[0015] 1. The air-supported membrane structure assembly inflation device accelerates airflow and introduces additional air by incorporating a centrifugal fan, venturi tube, and riser. The air inlet of the membrane structure is sealed to the diffuser section using connecting pipes and other devices. Then, the centrifugal fan and frequency converter are started. The fan body draws in external air through the inlet pipe and blows it into the outlet pipe. The outlet pipe transmits the airflow to the venturi tube. After compression in the storage section, the airflow is rapidly introduced into the throat section. Simultaneously, air from inside the riser is introduced into the structure, increasing the airflow volume and velocity into the membrane structure, thus achieving the effect of rapidly inflating more gas.

[0016] 2. This air-supported membrane structure assembly inflation device achieves precise airflow guidance and control through the installation of a frequency converter, air outlet duct, and venturi tube. Since the air outlet duct and venturi tube are sealed, the airflow from the centrifugal fan is guided, avoiding waste and maximizing the benefits of airflow into the membrane structure. Simultaneously, the frequency converter can adjust the voltage and frequency ratio of the centrifugal fan in real time according to actual load requirements, achieving precise control of the fan body and ensuring that the airflow from the venturi tube best meets current environmental needs. Users can also adjust parameters such as the voltage of the centrifugal fan via the frequency converter, thus achieving precise airflow guidance and control. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-2 An air-supported membrane structure assembly inflation device includes a housing 1. A protective frame 2 is symmetrically fixedly installed inside the housing 1. A centrifugal fan 3 is fixedly installed inside each protective frame 2. This device has two centrifugal fans 3: one is the main fan, and the other is a backup fan. This prevents the main fan from malfunctioning due to prolonged use during air supply; the backup fan can continuously supply air to the membrane structure, maintaining its stability. One side of the housing 1, located on one side of the protective frame 2, has evenly spaced heat dissipation holes 11 arranged in a linear array. The drive unit of the centrifugal fan 3 is located at the heat dissipation hole 11. The drive unit of the conventional centrifugal fan 3 is a motor, which generates heat during operation. This heat can be dissipated through the heat dissipation holes 11. One outlet is provided for heat dissipation. A rectangular slot is provided on the top of the housing 1, and an energy storage power supply 4 is movably installed inside the rectangular slot. The bottom of the energy storage power supply 4 is located above the protective frame 2. Inverter 5 is fixedly installed on both sides of the housing 1, diagonally above the protective frame 2. Inverter 5 is electrically connected to centrifugal fan 3, and the connecting wires between inverter 5 and centrifugal fan 3 can pass through the protective frame 2. In actual operation, inverter 5 can control the speed of centrifugal fan 3 to adjust the air volume and air force, avoiding the energy waste of traditional constant speed fans under low load conditions. Inverter 5 can also adjust the ratio of output voltage and frequency in real time according to the load requirements to achieve precise control of centrifugal fan 3. A venturi tube 6 is fixedly connected to the output end of centrifugal fan 3.

[0023] In practical applications, this device, through the coordination between the centrifugal fan 3 and the venturi tube 6, can accelerate air circulation and introduce more air through the riser 64, thereby blowing more air into the air-supported membrane structure. By setting two centrifugal fans 3, one as the main fan and the other as the backup fan, it avoids the main fan suddenly stopping during the blowing operation, which would prevent the air-supported membrane structure from being blown. In normal use, the main fan and the backup fan can be turned on simultaneously to accelerate the blowing of the air-supported membrane structure, or the main fan can be used alone for blowing, depending on the user's choice.

[0024] Please see Figures 1-3The centrifugal fan 3 is fixedly installed inside the protective frame 2. The protective frame 2 can protect the centrifugal fan 3 and make it easier to fix the position of the centrifugal fan 3 during installation. The centrifugal fan 3 includes a fan body 31. An air inlet pipe 32 is provided on one side of the fan body 31. The air inlet pipe 32 is connected to the outside of the box 1. An air outlet pipe 33 is provided on the top of the centrifugal fan 3. The two fan air outlet pipes 33 are connected to each other.

[0025] Please see Figures 1-2 The energy storage power supply 4 has symmetrical support legs 41 on both sides of its bottom. The bottom of the support legs 41 is located above the protective frame 2, so that there is a certain gap between the energy storage power supply 4 and the protective frame 2. The energy storage power supply 4 will generate a certain temperature when inputting and outputting current. If the energy storage power supply 4 and the protective frame 2 are installed on top of each other, the heat of the energy storage power supply 4 will not be able to dissipate quickly. The setting in this device allows the heat generated by the energy storage power supply 4 to be dissipated quickly. The heat can be discharged into the interior of the housing 1 through the heat dissipation holes 11 to achieve the heat dissipation effect. The top of the energy storage power supply 4 is symmetrically fixed with handles 42. When the user takes the energy storage power supply 4, he / she can lift the energy storage power supply 4 to quickly put or take it into the interior of the housing 1 to achieve quick installation.

[0026] Please see Figures 1-3 The venturi tube 6 is installed between the air outlet ducts 33, and the venturi tube 6 is connected to the air outlet ducts 33. The other end of the venturi tube 6 is located on one side of the housing 1 and can be connected to the air-supported structure through a connecting pipe. The venturi tube 6 includes a storage section 61, a throat section 62, a diffuser section 63, and a riser 64. The storage section 61 is connected to the air outlet duct 33. The diffuser section 63 is installed on the side wall of the housing 1 and communicates with the outside of the housing 1. The throat section 62 is located between the storage section 61 and the diffuser section 63, and the storage section 61, the throat section 62, and the diffuser section 63 are connected. A riser 64 is provided at the top of the throat section 62. The end of the pipe 64 extends outside the box 1 and is in communication with the outside air. When the Venturi pipe 6 is actually working, the continuous blowing of the fan body 31 causes the air to be discharged from the air outlet pipe 33 into the interior of the Venturi pipe 6. After the air is compressed by the collection section 61, it can accelerate the air flow inside the riser 64 when it passes through the throat section 62. Then it is diffused and discharged through the diffuser section 63. When the Venturi pipe 6 is used for exhaust, its original air force is compressed and discharged through the throat section 62, and at the same time, it can induce the air inside the riser 64 to join it, thereby accelerating the air circulation and blowing more air into the air-supported structure.

[0027] Working Principle: During operation, the air inlet of the air-supported membrane structure is sealed to the diffuser section 63 using connecting pipes and other devices. Then, the centrifugal fan 3 and frequency converter 5 are started. The fan body 31 draws in external air through the inlet pipe 32 and blows it into the outlet pipe 33. The outlet pipe 33 transmits the airflow to the venturi tube 6, where it is compressed by the collection section 61, causing it to flow rapidly at the throat section 62. Simultaneously, air from the riser 64 is introduced, increasing the airflow volume and velocity into the air-supported membrane structure, achieving rapid airflow. Since the outlet pipe 33 and the venturi tube 6 are sealed, the airflow from the centrifugal fan 3 is guided, preventing waste and maximizing the efficiency of airflow into the air-supported membrane structure. Simultaneously, the frequency converter... The inverter 5 can adjust the voltage and frequency ratio of the centrifugal fan 3 in real time according to the actual load requirements, so as to achieve precise control of the fan body 31 and make the air force blown by the venturi tube 6 best meet the current environmental requirements. Users can also adjust the voltage and other parameters of the centrifugal fan 3 through the inverter 5. When blowing air into the air-supported structure, different gases, such as hydrogen, can also be introduced into the riser 64 to adjust the weight of the gas in the air-supported structure. If the main fan fails and cannot work, the backup fan will be started immediately. Both the main fan and the backup fan are connected to the inverter 5, and the inverter 5 can also control the backup fan in real time. In case of emergencies such as power failure, both the main fan and the backup fan can be powered by the energy storage power supply 4. The energy storage power supply 4 is convenient for users to quickly take and replace.
