Description

Technical Field

[0001] This utility model relates to the field of air-supported membrane building technology, specifically to an adaptive pressure control device for air-supported membrane buildings. Background Technology

[0002] Air-supported membrane structures are enclosed space structures made of high-strength flexible membrane materials. They maintain their shape by continuously supplying air through an inflation device, which mainly consists of a fan, a pressure control system, and an intelligent monitoring device. It can automatically adjust the air pressure according to environmental changes and has advantages such as rapid construction, energy saving and environmental protection, and large spatial span. It is widely used in sports stadiums, warehousing and logistics and other fields.

[0003] Traditional air-supported membrane structures lack a high-precision detection structure during inflation, and cannot adjust the blower's operation in real time according to the detected pressure. Their adaptive effect during regulation is not good, and the adjustment accuracy is low. Utility Model Content

[0004] To address the problems in existing technologies, this utility model provides an adaptive pressure control device for air-supported membrane structures. During inflation, it features a detection structure with high precision, which can adjust the operation of the blower in real time according to the detected pressure. This results in better adaptive performance and higher adjustment accuracy during control.

[0005] The technical solution adopted by this utility model to solve its technical problem is an adaptive pressure control device for air-supported membrane structures, including a mounting frame and a detection mechanism. A blower for blowing air onto the air-supported membrane is screwed onto one end of the top of the mounting frame. The detection mechanism includes:

[0006] The switch is located on the top of the mounting bracket, away from the blower.

[0007] Multiple groups are set up for fiber optic testing.

[0008] A fiber optic pressure detector, wherein the signal input end of the fiber optic pressure detector is connected to the detection fiber, and the signal output end of the fiber optic pressure detector is connected to the LAN port of the switch via a LAN port network cable;

[0009] The PLC is located at the top of the mounting bracket, near the switch and the blower, and its signal input terminal is connected to the WAN port of the switch via a network cable.

[0010] The rotating blades and rotating shaft of the blower are driven by a servo motor, and the controlled end of the servo motor is electrically connected to the signal output end of the PLC through a control cable.

[0011] By adopting the above technical solution, the detection optical fibers are distributed on the inner wall of the air film during operation. When the air film is filled with air, the detection optical fibers distributed at various locations on the inner wall of the air film can easily detect the air pressure near their location and transmit the signal to the corresponding fiber optic pressure detector. Each group of fiber optic pressure detectors then transmits the signal to the switch via the LAN port network cable, and then transmits the signal to the PLC via the WAN port of the switch and a set of network cables.

[0012] Specifically, a conical plug is provided around the periphery of the detection optical fiber near the optical fiber pressure detector, and an annular sealing groove is formed around the end of the conical plug away from the optical fiber pressure detector.

[0013] By adopting the above technical solution, a conical sleeve is pre-embedded at the opening corresponding to the detection optical fiber on the inner wall of the air film. The shape of the inner wall of the conical sleeve is the same as the shape of the outer side of the conical plug, and a sealing groove corresponding to the annular sealing groove is opened on the inner wall of the conical sleeve. By arranging a sealing ring in the annular sealing groove, when the detection optical fiber is squeezed by the pressure inside the air film, the head of the conical plug is inserted into the conical sleeve on the inner wall of the air film to seal the threading position of the detection optical fiber on the air film. The sealing effect can be effectively improved by the sealing ring.

[0014] Specifically, multiple sets of fixing plates are provided on the outer side of the detection optical fiber, and the multiple sets of fixing plates are evenly distributed along the length direction of the detection optical fiber.

[0015] By adopting the above technical solution, an internal thread sleeve is also pre-embedded in the inner wall of the air film. The fixing plate can be fixed to the inner wall of the air film by passing an external screw through the mounting hole on the fixing plate and locking it with the internal thread sleeve. The fixing plate can facilitate the limiting of the detection optical fiber.

[0016] Specifically, each of the two sets of L-shaped mounting brackets is fixed with screws at one end of the top of the mounting bracket near both sides. T-shaped guide rails are installed on the inner side of the top of the two sets of L-shaped mounting brackets with screws. A T-shaped slider is fitted inside the T-shaped guide rail. A locking screw is provided on the top of the T-shaped slider through a threaded groove. The locking end face of the locking screw is located on the upper side of the T-shaped guide rail.

[0017] By adopting the above technical solution, the horizontal position of the T-shaped slider can be easily adjusted as needed by sliding the T-shaped slider within the T-shaped guide rail. By tightening the locking screw, the locking surface of the locking screw head contacts the top of the T-shaped guide rail, thereby fixing the horizontal position of the T-shaped slider.

[0018] Specifically, the bottom of the T-shaped slider is connected to a support block, and a reserved slot is opened through one end of the support block. A wire loop is set in the reserved slot, and the LAN port network cable passes through the corresponding wire loop.

[0019] Specifically, the threading ring is made of rubber.

[0020] Specifically, a limiting protrusion is provided on the outer side of the end of the detection optical fiber away from the optical fiber pressure detector.

[0021] Specifically, the fixing plate is made of POM material.

[0022] The beneficial effects of this utility model are:

[0023] (1) The adaptive pressure control device for air-supported membrane structures described in this utility model transmits the signal of the fiber optic pressure detector to the switch via the LAN port network cable. The switch then transmits the signal to the PLC. The PLC adaptively adjusts and controls the speed of the blower, thereby adjusting the air intake speed of the air-supported membrane. This control device has a high-precision detection structure during inflation and can adjust the operation of the blower in real time according to the detected pressure. It has a better adaptive effect and higher adjustment accuracy during control. Attached Figure Description

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To ensure the control device possesses a highly accurate detection structure during inflation, facilitating real-time adjustment of the blower's operation based on the detected pressure, thereby enhancing its adaptive effect and improving adjustment precision, such as... Figure 1-5 As shown, the adaptive pressure control device for air-supported membrane structures according to this utility model includes a mounting frame 1 and a detection mechanism. A blower 4 for blowing air onto the air-supported membrane is screwed onto one end of the top of the mounting frame 1. The detection mechanism includes:

[0033] Switch 3 is located on the top of mounting bracket 1 on the side away from blower 4;

[0034] Fiber 6 is used for detection, and multiple groups are configured.

[0035] The fiber optic pressure detector 5 has its signal input end connected to the detection fiber optic cable 6, and its signal output end connected to the LAN port of the switch 3 via a LAN port cable 12.

[0036] PLC2 is located at the top of the mounting bracket 1, near the switch 3 and the blower 4, and its signal input terminal is connected to the WAN port of the switch 3 via a network cable.

[0037] The rotating blades and rotating shaft of the blower 4 are driven by a servo motor, and the controlled end of the servo motor is electrically connected to the signal output end of the PLC2 through a control cable.

[0038] In use, the detection optical fibers 6 are distributed on the inner wall of the air membrane. When the air membrane is inflated, the detection optical fibers 6 distributed at various locations on the inner wall of the air membrane can easily detect the air pressure near their location and transmit the signal to the corresponding fiber optic pressure detector 5. Each group of fiber optic pressure detectors 5 then transmits the signal to the switch 3 via the LAN port network cable 12, and then transmits the signal to the PLC2 via the WAN port of the switch 3 and a set of network cables, thus completing the transmission of multiple groups of branch detection signals.

[0039] For example, such as Figure 1 , Figure 2 and Figure 5 As shown, the present invention also includes a conical plug 8 disposed around the periphery of the detection optical fiber 6 near the optical fiber pressure detector 5, and an annular sealing groove 9 formed around the periphery of the end of the conical plug 8 away from the optical fiber pressure detector 5.

[0040] In use, a conical sleeve is pre-embedded at the opening corresponding to the detection optical fiber 6 on the inner wall of the air film. The shape of the inner wall of the conical sleeve is the same as the shape of the outer side of the conical plug 8, and a sealing groove corresponding to the annular sealing groove 9 is opened on the inner wall of the conical sleeve. By arranging a sealing ring in the annular sealing groove 9, when the detection optical fiber 6 is squeezed by the pressure inside the air film, the head of the conical plug 8 is inserted into the conical sleeve on the inner wall of the air film to seal the threading position of the detection optical fiber 6 on the air film. The sealing effect can be effectively improved by the sealing ring.

[0041] For example, such as Figure 1-2 As shown, the present invention also includes multiple sets of fixing plates 7 arranged on the outer side of the detection optical fiber 6, and the multiple sets of fixing plates 7 are evenly distributed along the length direction of the detection optical fiber 6.

[0042] During use, an internal thread sleeve is pre-embedded in the inner wall of the air membrane. The fixing plate 7 can be fixed to the inner wall of the air membrane by passing an external screw through the mounting hole on the fixing plate 7 and locking it with the internal thread sleeve. The fixing plate 7 can also be used to limit the movement of the detection optical fiber 6.

[0043] For example, such as Figure 1-4 As shown, this utility model also includes an L-shaped mounting bracket 10 fixed to one end of the top of the mounting bracket 1 near both sides by screws. T-shaped guide rails 11 are installed on the inner side of the top of the two sets of L-shaped mounting brackets 10 by screws. A T-shaped slider 15 is sleeved inside the T-shaped guide rail 11. A locking screw 16 is provided on the top of the T-shaped slider 15 through a threaded groove. The locking end face of the head of the locking screw 16 is located on the upper side of the T-shaped guide rail 11.

[0044] In use, the T-shaped slider 15 slides within the T-shaped guide rail 11, allowing for easy adjustment of its horizontal position as needed. By tightening the locking screw 16, the locking surface of the screw head contacts the top of the T-shaped guide rail 11, thereby fixing the horizontal position of the T-shaped slider 15.

[0045] For example, such as Figure 1 , Figure 2 and Figure 4 As shown, the present invention also includes a support block 13 connected to the bottom of the T-shaped slider 15, a reserved groove being provided through one end of the support block 13, and a wire threading ring 14 being provided in the reserved groove, through which the LAN port network cables 12 pass.

[0046] In use, the T-shaped slider 15 facilitates the fixed connection between the support block 13 and the cable threading ring 14, and the cable threading ring 14 facilitates the threading of the LAN port network cable 12, making the LAN port network cable 12 neater.

[0047] For example, such as Figure 4As shown, the present invention also includes a threading ring 14 made of rubber material.

[0048] During use, a threading ring 14 made of rubber material is used to effectively protect the outer wall of the LAN port network cable 12 when the detection optical fiber 6 passes through the threading ring 14, reducing contact wear.

[0049] For example, such as Figure 1-2 As shown, the present invention also includes a limiting protrusion provided on the outer side of the end of the detection optical fiber 6 away from the optical fiber pressure detector 5.

[0050] During use, the limiting protrusion can effectively prevent the fixed pressure plate 7 from detaching from the inside of the fixed pressure plate 7 when squeezed by the internal pressure of the air film, which would have an adverse effect on the test results.

[0051] For example, such as Figure 1-2 As shown, the present invention also includes a fixing plate 7 made of POM material.

[0052] When in use, the fixing plate 7 made of POM material has good strength. When it is fixed to the inner wall of the air film and subjected to large pressure, it is not easily damaged, does not easily rust, and has good durability.

[0053] When in use, all electrical equipment of this control device is connected to an external power source for power supply.

[0054] An internal thread sleeve is also pre-embedded in the inner wall of the air film. The fixing plate 7 can be fixed to the inner wall of the air film by passing an external screw through the mounting hole on the fixing plate 7 and locking it with the internal thread sleeve. The fixing plate 7 can be used to limit the detection optical fiber 6. The limiting protrusion can effectively prevent the fixing plate 7 from detaching from the inside of the fixing plate 7 when squeezed by the internal pressure of the air film, which would have an adverse effect on the detection results.

[0055] A conical sleeve is pre-embedded at the opening corresponding to the detection optical fiber 6 on the inner wall of the air film. The shape of the inner wall of the conical sleeve is the same as the shape of the outer side of the conical plug 8. A sealing groove corresponding to the annular sealing groove 9 is opened on the inner wall of the conical sleeve. By arranging a sealing ring in the annular sealing groove 9, when the detection optical fiber 6 is squeezed by the pressure inside the air film, the head of the conical plug 8 is inserted into the conical sleeve on the inner wall of the air film to seal the threading position of the detection optical fiber 6 on the air film. The sealing effect can be effectively improved by the sealing ring.

[0056] The T-shaped slider 15 slides within the T-shaped guide rail 11, allowing for easy adjustment of its horizontal position as needed. By tightening the locking screw 16, the locking surface of the screw head contacts the top of the T-shaped guide rail 11, thus fixing the horizontal position of the T-shaped slider 15. The T-shaped slider 15 facilitates the fixed connection between the support block 13 and the cable threading ring 14. The cable threading ring 14 facilitates the threading of the LAN port network cable 12, and the positions of the cable threading ring 14 and the support block 13 can be adjusted as the T-shaped slider 15 slides, making it easier to manage the LAN port network cable 12 and resulting in a neater appearance.

[0057] The detection optical fibers 6 are distributed along the inner wall of the air membrane during operation. When the air membrane is inflated, the detection optical fibers 6 distributed at various points along the inner wall of the air membrane can easily detect the air pressure near their location and transmit the signal to the corresponding fiber optic pressure detector 5. Each group of fiber optic pressure detectors 5 then transmits the signal to the switch 3 via the LAN port network cable 12, and then to the PLC2 via the WAN port of the switch 3 and a set of network cables. After analyzing the pressure value signals detected by the multiple groups of detection optical fibers 6, the PLC2 sends a control signal to the servo motor of the blower 4, thereby adaptively adjusting the speed of the blower 4 according to the pressure detected at multiple points in the air membrane, that is, adjusting the air intake speed of the air membrane. This control device has a detection structure with high precision during inflation and can adjust the operation of the blower in real time according to the detected pressure, resulting in better adaptive effect and higher adjustment accuracy during control.
