Description

Technical Field

[0001] This disclosure belongs to the field of air-supported membrane equipment technology, and more specifically relates to an air-supported membrane space medium interaction device. Background Technology

[0002] As is well known, the working principle of an air-supported membrane structure is to tension a lightweight membrane material through the pressure difference between the inside and outside, thereby forming an airtight span. However, because the workplace is located in an airtight space, the air flow within the airtight space is relatively slow, and the air quality cannot be fully guaranteed during use.

[0003] Existing air-supported membrane structures use pre-reserved openings in the lower structure with exhaust devices for ventilation. Under pressure, the gas is discharged in an organized manner, thus exchanging air in the airtight space. However, due to the characteristics of air-supported membrane structures, hot air, water vapor, and flue gas accumulated in the upper area cannot be efficiently discharged. This means that the bottom exhaust method cannot effectively exchange the gas medium at the top of the air-supported membrane structure.

[0004] To address this issue, existing air-supported membrane structures also include ventilation ports at the top. Because these ports are located at the top of the airtight space, the gaseous medium within the space can be effectively expelled, accelerating gas flow, improving gas exchange efficiency, and ultimately meeting the environmental quality requirements of the air-supported membrane structure.

[0005] However, because the ventilation vents cannot be closed and controlled, the airtightness of the air-supported membrane equipment is compromised, increasing energy consumption. At the same time, in inclement weather such as rain, the ventilation vents cannot be closed, causing rainwater or other contaminants to enter the airtight space, affecting the use of the work site.

[0006] Therefore, there is an urgent need to develop a controllable device for media exchange between the inside and outside of a gas membrane. Summary of the Invention

[0007] To address the problems in the prior art, this disclosure provides a device for interaction between the internal and external spatial media of an air-supported membrane.

[0027] The flow guide is disposed on the inflatable membrane structure and located on the opposite side of the medium exchange component, and is used to guide the gas discharged within the span space.

[0028] The flow guide includes:

[0029] The first part is a detachable connection at one end to the connecting component;

[0030] The second part is connected to the first part at one end and faces outward from the span space at the other end, and is used to discharge the gas in the span space.

[0031] Both the first and second parts are flexible components and are integrally formed.

[0032] The media switching component includes:

[0051] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0053] This disclosure provides an embodiment:

[0054] like Figure 1 A device for media interaction between the inside and outside of an air-supported membrane space includes: an inflatable membrane structure 1 for forming a span space after inflation, a media exchange component 2, and a connecting component 3; wherein, the media exchange component 2 is disposed on the inner side of the inflatable membrane structure 1; the inflatable membrane structure 1 is provided with a media exchange hole 1A for media flow; the media exchange component 2 is correspondingly disposed to the media exchange hole 1A, for controllably connecting the gas medium in the span space with the outside.

[0055] In this embodiment, the gas medium in the span space is exchanged by opening or closing the controllable medium exchange component 2 according to the gas conditions in the span space, which can improve the airtightness of the air film equipment and reduce energy consumption.

[0056] Furthermore, such as Figure 2 As shown, the connecting component 3 is disposed between the inflatable membrane structure 1 and the medium exchange component 2, and the medium exchange component 2 can be detachably disposed on the inflatable membrane structure 1, ensuring that the medium exchange component 2 is easy to disassemble and install.

[0057] Preferably, the connecting component 3 includes: a first connector 301, a second connector 302, and a third connector 303; wherein, the first connector 301 is disposed on the medium exchange component 2; the second connector 302 is disposed above the inflatable membrane structure 1; and the third connector 303 is disposed between the first connector 301 and the second connector 302, for mounting the medium exchange component 2 on the inflatable membrane structure 1.

[0058] Optionally, the first connector 301 can be an inwardly flanged workpiece made of any metal material, such as aluminum alloy or other metals, and can be fixed to the medium exchange assembly 2 by welding or bolting; the second connector 302 is a flange-shaped workpiece with a diameter larger than the medium exchange hole 1A; the third connector 303 is a bolted part, and a corresponding flange hole is provided on the inflatable membrane structure 1, so as to facilitate the installation of the first connector 301 and the second connector 302 onto the inflatable membrane structure 1 using the third connector 303. Specific Implementation Example 2:

[0060] In specific embodiment 1, the first connector 301 and the second connector 302 are installed onto the inflatable membrane structure 1 by the third connector 303; however, since the medium exchange component 2 itself has a certain weight, when it is installed onto the inflatable membrane structure 1, it is only fixed by the third connector 303, and a relative displacement will inevitably occur between the inflatable membrane structure 1 and the medium exchange component 2; once a relative displacement occurs, it will generate a large tensile force on the inflatable membrane structure 1, causing tearing and affecting the safety of the inflatable membrane structure 1.

[0061] To solve this problem, such as Figure 3-4Based on specific embodiment 1, this embodiment provides a reinforcing mechanism 304 inside the connecting component 3, so that the third connecting member 303 simultaneously connects the first connecting member 301, the second connecting member 302 and the reinforcing mechanism 304, increasing the strength of the air membrane structure 1 at the edge of the medium exchange hole and preventing the air membrane structure 1 from tearing due to excessive force. Furthermore, the reinforcing mechanism can also prevent the air membrane structure from tearing when the air membrane and the medium exchange component move relative to each other.

[0062] Preferred, such as Figure 5 The reinforcing mechanism 304 includes: an embedded part 3041 and at least one flexible part 3042; wherein, the embedded part 3041 is disposed on the side of the inflatable membrane structure facing the outside and close to the medium exchange hole; the flexible part is disposed on the inner wall of the medium exchange hole; the embedded part is disposed between the flexible part and the inflatable membrane structure to form a limiting structure to restrict the movement of the first connector or the second connector.

[0063] Specifically, the limiting structure can be configured as follows:

[0064] like Figure 6 One end of the aforementioned flexible member 3042 is connected to the inner wall of the medium exchange hole 1A; the inflatable membrane structure 1 is provided with a first through hole 1B for the passage of the third connector 303; the end of the flexible member 3042 away from the medium exchange hole 1A is provided with a second through hole 3042A for the passage of the third connector 303, for wrapping the embedded part 3041 through the flexible member 3042 when cooperating with the third connector 303; optionally, the material of the flexible member 3042 is the same as that of the inflatable membrane structure 1, and it is welded to the inflatable membrane structure 1 to ensure strength. The reinforcing mechanism 304 is a reinforcing part of the edge of the medium exchange hole 1A. When the inflatable membrane structure 1 at the edge of the medium exchange hole 1A is subjected to force, the force is transmitted to the embedded part 3041, and the embedded part 3041 prevents the inflatable membrane structure 1 from being torn under the action of external force.

[0065] In specific installations, to save costs and facilitate installation, such as Figure 5 At the location where a medium exchange hole 1A needs to be opened, the inflatable membrane structure 1 is cut along the cutting line S to obtain four fan-shaped areas, which serve as flexible components 3042. A first perforation 1B and a second perforation 3042A are opened at the corresponding locations. Then, after placing the embedded part 3041, the fan-shaped areas are folded over to wrap the embedded part 3041, and then fastened and pressed together using the third connector 303. Due to the presence of the embedded part 3041, it can simultaneously limit the movement and prevent tearing of the first connector 301 and the second connector 302. In this embodiment, the embedded part 3041 can be an embedded rope or other optional workpiece.

[0066] Specifically, the limiting structure can also be configured as follows:

[0067] like Figure 7 The aforementioned flexible element 3042 is a ring-shaped element. When the flexible element 3042 is welded onto the inflatable membrane structure 1, the embedded element 3041 is sandwiched between the flexible element 3042 and the inflatable membrane structure 1. Similarly, the limiting structure is set at the edge of the medium exchange hole 1A. When the inflatable membrane structure 1 at the edge of the medium exchange hole 1A is subjected to force, the force is transmitted to the embedded element 3041. Through the embedded element 3041, the inflatable membrane structure 1 is prevented from being torn by external force. Specific Implementation Example 3:

[0069] Based on specific embodiment 2, since a medium exchange component 2 is provided below the medium exchange hole 1A, and the air pressure inside the inflatable membrane structure 1 is greater than the external air pressure, when the medium exchange component 2 is opened, the medium inside the inflatable membrane structure 1 will be discharged from the medium exchange hole 1A. However, if the medium discharged from inside the inflatable membrane structure 1 may contain dust particles, they will accumulate around the outside of the medium exchange hole 1A, affecting both aesthetics and service life.

[0070] To address this issue, in this embodiment, as follows: Figure 8 The aforementioned air-film space internal and external spatial medium interaction device further includes a flow guide 4. This flow guide 4 is disposed on the air-filled membrane structure 1 and located on the opposite side of the medium exchange component 2, for guiding the gas discharged within the span space.

[0071] In this embodiment, as Figure 9 The flow guide 4 includes a first part 401 and a second part 402; wherein one end of the first part 401 is pressed into the connecting assembly 3; one end of the second part 402 is connected to the first part 401, and the other end faces the outside of the span space for discharging gas in the span space; preferably, the second part 402 is cylindrical; preferably, the first part 401 and the second part 402 can be integrally formed.

[0072] When the medium exchange component 2 is opened and the medium is discharged, the second part 402 is cylindrical in shape, forming a chimney-like structure, thereby accelerating the discharge of particles present in the medium away from the medium exchange hole 1A and reducing the probability of them falling onto the smooth surface of the inflatable membrane structure 1.

[0073] It should be noted that:

[0074] The media exchange component 2 described in specific embodiments 1, 2 and 3 includes: a media exchange unit 201, a drive unit 202 and a control unit 203; wherein, the drive unit 202 is connected to the media exchange unit 201 and is used to drive the media exchange unit 201 to open / close; the control unit 203 is electrically connected to the drive unit 202 and is used to send control signals to control the start and stop of the drive unit 202.

[0075] Among them, such as Figure 10 The media exchange unit 201 can be a structure similar to a louver, with a circular outer frame and at least one blade 201A inside; the blade 201A in the media exchange unit 201 is driven to move synchronously by the drive unit 202 to achieve the purpose of closing or opening.

[0076] During installation, you can use, for example Figure 11 A support layer 201AA is provided on the side of the frame of the medium exchange unit 201 near the inflatable membrane structure 1. A threaded hole for connecting the medium exchange unit 201 is provided on the support layer 201AA, such as at point M. Alternatively, the flexible membrane can be connected via the support layer 201AA before connecting the medium exchange unit 201. The multiple threaded holes disperse the tensile force generated when the medium exchange unit 201 shakes, preventing tearing of the inflatable membrane structure 1. Preferably, the area of ​​the support layer 201AA is much larger than the medium exchange hole 1A.

[0077] In this embodiment, the drive unit 202 can be any actuator, such as a stepper motor; the control unit 203 can be a microcontroller or other programmable control unit.

[0078] It should be noted that all other technologies not covered in this article are existing technologies and will not be elaborated upon.

[0079] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any changes or substitutions made by those skilled in the art within the scope of the technology disclosed in this disclosure are all within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure is determined by the scope of the claims.
