[0070] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Specific embodiment 1:

[0072] The present disclosure provides an embodiment:

[0073] As Figure 1 A medium exchange controllable air film device, comprising: an inflatable membrane structure 1, a medium exchange assembly 2; wherein the inflatable membrane structure 1 is used to form a span space after inflation; the medium exchange assembly 2 is arranged on the inflatable membrane structure and is arranged towards the outside; the inflatable membrane structure is provided with a through hole 1A for medium flow; the medium exchange assembly 2 is arranged on the side of the through hole 1A towards the outside, and is used to controllably close / open to control the medium flow in the span space.

[0074] In this embodiment, the main function of the medium exchange assembly 2 is to controllably close / open, so as to change the state of the through hole 1A, and when opened, the medium exchange efficiency in the span space can be improved, and when closed, the air tightness of the span space can be ensured, and energy consumption can be saved.

[0075] Further, the medium exchange assembly 2 comprises a medium exchange member 201, a driving unit 202 and an opening and closing mechanism 203; wherein the medium exchange member 201 is detachably arranged outside the inflatable membrane structure 1 and located on the side of the through hole 1A towards the outside, and is used to provide a passage for medium flow; the opening and closing mechanism 203 is arranged inside the medium exchange member 201; the driving unit 202 is in transmission connection with the moving member 203, and is used to drive the moving member 203 to close / open the passage.

[0076] In this embodiment, the driving unit 202 recorded in this embodiment can be a stepping motor; the driving unit 202 can be connected to a control unit, such as a single-chip microcomputer or other programmable control unit, for drive control; when it is necessary to close / open the channel, a control signal is sent through the control unit to control the driving unit 202 to drive the opening and closing mechanism 203 to move to close / open the channel.

[0077] like Figure 2 In specific embodiment 1, since the medium exchange element 201 is directly installed on the inflatable membrane structure 1, and the inflatable membrane structure 1 itself has insufficient rigidity, this will cause the medium exchange element 201 to shake, and the membrane body at the edge of the through hole 1A is at risk of being torn by external force.

[0078] In order to solve this problem, the air membrane device with controllable medium exchange described in this embodiment also includes: a reinforcement 5; the reinforcement 5 is arranged between the medium exchange component 201 and the inflatable membrane structure 1 to increase the connection area between the membrane body and the exchange component, so as to improve the connection strength of the medium exchange component 201; at the same time, it can also enhance the wear resistance; the reinforcement 5 can be an aluminum alloy flange or other workpiece.

[0079] It should be noted that: Figure 2 In the embodiment, embedded part 1AA is present; embedded part 1AA is formed by folding the inflatable membrane structure 1 after opening 1A. Embedded part 1AA is wrapped around folded part 1B and the inflatable membrane structure 1, and then the excess folded part 1B is welded to the inflatable membrane structure 1. During use, the embedded part 1AA restricts the movement of the medium exchange element 201, and the force of movement is concentrated on embedded part 1AA, ensuring that the inflatable membrane structure 1 is not torn. Optionally, embedded part 1AA is an embedded rope.

[0080] In specific embodiment 2:

[0081] In specific embodiment 1, although a structure for fixing the medium exchange component 201 is provided, it is found in actual use that the structure still has certain hidden dangers, which may cause abnormal conditions such as the medium exchange component 201 being skewed, thus affecting use.

[0082] In view of this, the medium exchange controllable air film device described in this embodiment, such as Figure 3 , also includes: a connecting component 3 for fixing the medium exchange component 2; specifically, the connecting component 3 includes: a first connecting mechanism 301, a connecting member 302 and a second connecting mechanism 303; wherein, the first connecting mechanism 301 is arranged on the outside of the medium exchange member 201; the second connecting mechanism 303 is arranged on the outside of the inflatable membrane structure 1.

[0083] In the embodiment, the medium exchange 201 is reliably fixed outside the inflatable membrane structure 1 by the combination of the first connecting mechanism 301, the second connecting mechanism 303 and the connecting piece 302.

[0084] Further, as Figure 4 , the first connecting mechanism 301 comprises a transition piece 3011, two matching pieces 3012 and a fastener 3013; the transition piece 3011 is arranged outside the medium exchange 201 by welding; the matching piece 3012 is arranged on the transition piece 3011 by welding or other means, used for connecting the connecting piece 302; the fastener 3013 is arranged on the matching piece 3012, used for detachably arranging the connecting piece 302 in the matching piece 3012.

[0085] In the embodiment, as Figure 5 , the matching piece 3012 can be a square tube; the connecting piece 302 is a square piece, and a groove 302A is arranged on the outer surface of the connecting piece 302; the matching piece 3012 is slidably sleeved outside the connecting piece 302; the fastener 3013 can be a groove-in-nut fastening structure to fix the connecting piece 302 and the matching piece 3012 together.

[0086] Further, as Figure 6 , the second connecting mechanism 303 comprises a first crimping piece 3031, a second crimping piece 3032, a fastening structure 3033, a support piece 3034 and two third crimping pieces 3035; the second crimping piece 3032 is arranged in matching with the first crimping piece 3031; one end of the fastening structure 3033 connects the first crimping piece 3031 and the second crimping piece 3032, used for fixing the combination of the first crimping piece 3031 and the second crimping piece 3032 outside the inflatable membrane structure 1; the support piece 3034 is detachably connected with the other end of the fastening structure 3033; the third crimping piece 3035 is arranged on the support piece 3034; the connecting piece 302 is detachably arranged between the third crimping piece 3035 and the support piece 3034.

[0087] Preferably, as Figure 7 , in order to match the requirement that the connecting piece 302 is a square piece, the third crimping piece 3035 is a door-shaped structure, and threaded fixing structures are arranged at both ends of the third crimping piece 3035 and arranged on the support piece 3034. Meanwhile, as Figure 8 , the fastening structure 3033 is a column with threads at both ends, and a certain variable diameter exists at the threaded ends as a connecting limiting structure to fix the first crimping piece 3031, the second crimping piece 3032 and the support piece 3034.

[0088] In specific use, the medium exchanger 201 is fixed on the inflatable membrane structure 1 by the connecting assembly 3, and since the connecting member 302 has a certain length, such as 3 m, the force arm length of the medium exchanger 201 on the inflatable membrane structure 1 is undoubtedly increased, and the use stability of the medium exchanger 201 is increased. Specific embodiment 3:

[0090] It can be predicted that in specific embodiment 2, since the inflatable membrane structure 1 is flexible, even if the connecting assembly 3 is added to increase the force arm length, the medium exchanger 201 will still shake during use.

[0091] In order to solve this problem, in use, in addition to using the inflatable membrane structure 1, each air film device also needs to use a tensioning member 4, such as a steel cable, to tension the inflatable membrane structure 1. The tensioning member 4 itself has good stability. Therefore, in this embodiment, as shown in Figure 8 , a groove 3031B for arranging the tensioning member 4 is arranged on the first crimping member 3031, and the first crimping member 3031 and the tensioning member 4 are fixed together to further increase the connection strength and improve the use reliability.

[0092] However, since the angle of the tensioning member 4 is variable, in order to improve the use range, as shown in Figure 9 , three evenly distributed through holes 3031C and arc-shaped long holes 3031A for arranging the fastening structure 3033 are arranged on the first crimping member 3031; similarly, the second connecting mechanism 303 can be a round plate, which also has the same through holes and arc-shaped long holes as the first crimping member 3031, and the positions and angles thereof are consistent with those of the first crimping member 3031, which plays a role in crimping the tensioning member 4. Specific embodiment 4:

[0094] The opening and closing mechanism 203 described in specific embodiment 1 can be selected from a variety of structures, and two structures are provided in this embodiment for reference.

[0095] Specifically, as shown in Figure 10 , the opening and closing mechanism 203 comprises: a movable member 2031 and a shaft portion 2032; wherein the movable member 2031 is arranged in the medium exchanger 201, and the medium exchanger 201 is cylindrical; the shaft portion 2032 penetrates the movable member 2031 to improve the rotation torque and the rotation effect; the shaft portion 2032 is connected with the output end of the driving unit 202, and is used to drive the movable member 2031 to flip to close the medium flow passage of the medium exchanger 201 by the driving unit 202; in this structure, the movable member 2031 forms a structure similar to a butterfly valve in the medium exchanger 201. Preferably, the arrangement direction of the shaft portion 2032 in the opening and closing mechanism 203 is consistent with the arrangement direction of the connecting member 302, which can increase the running stability.

[0096] In this embodiment, if Figure 11 The air film device with controllable medium exchange further includes: a shielding member 6 arranged on the side of the medium exchange member 201 facing the outside, which can be used to prevent rain; preferably, the shielding member 6 is in a cone-shaped shape, which can effectively improve the rain and dust prevention effects. Specific embodiment 5:

[0098] The medium exchange component 2 in the specific embodiments 1-3 adopts the structure of the medium exchange component 201, the drive unit 202 and the opening and closing mechanism 203; in order to provide more technical solutions, this embodiment provides the following medium exchange component 2, which is connected to the fixing mechanism, and the fixing mechanism can cooperate with the tensioning member 4 for fixation.

[0099] like Figure 12 The medium exchange component 2 includes: at least one blade 204, a frame body 205, and a drive unit 202; wherein the blade 204 is arranged in the frame body 205, and the drive unit 202 drives the blade 204 to move simultaneously, thereby playing an opening and closing role. The end of the frame body 205 is provided with an extension portion 205A; the extension portion 205A is connected to the fixing mechanism through a fastening structure such as a bolt; the fixing mechanism includes a first fixing member and a fixing group; the first fixing member can be a workpiece similar to the connection 302; the structure of the fixing group can refer to the structure of the second connecting mechanism 303; after the first fixing member and the fixing group are connected, similar to the connection between the second connecting mechanism 303 and the connecting member 302, and then connected with the tensioning member 4, the specific structure can be referred to. Figure 6 .

[0100] In order to ensure airtightness, in this embodiment, Figures 13-15 The medium exchange component 2 also includes: a soft connector 206, one end of which is arranged on the periphery of the frame body 205 through a structure such as a bolt, and the other end is arranged near the outer wall or inner wall of the through hole 1A; in this embodiment, if the frame body 205 is square, the soft connector 206 constitutes a square-to-circle structure.

[0101] like Figures 16 If the frame body 205 is circular, then on the side of the circular frame body 205 close to the inflatable membrane structure 1, the frame body 205 is directly connected to the inflatable membrane structure 1 through the first bolt hole 205B1 on the supporting layer 205B, or the inflatable membrane structure 1 is connected after the flexible connection. ​Meanwhile, the support layer 205B is provided with a hole corresponding to the through hole 1A; and the support layer 205B is provided with a plurality of second bolt holes 205B2 corresponding to the connecting piece 302; preferably, the number of the second bolt holes 205B2 can be multiple, such as 12, and are arranged in two rows respectively to connect two different connecting pieces 302; due to the arrangement of the plurality of second bolt holes 205B2, when the frame body 205 shakes, the pulling force caused by the shaking can be dispersed, and the overall structure is more stable. Preferably, the area of the support layer 205B is much larger than the through hole 1A.
