Description

Technical Field

[0001] The present application relates to the field of air membranes, and in particular to a protective cover. Background Art

[0002] An air membrane structure is a structural form that uses air pressure to support the structure. Due to its flexibility and mobility, it is widely used in art projects, exhibitions, pavilions, temporary shelters and other fields. Among them, the large-span air-ribbed air membrane adopts a modular design, which can be easily deflated and inflated, convenient for transportation and reuse, and can be quickly assembled and disassembled. It is self-supporting, lightweight, energy-saving and low-consumption.

[0003] In the field of spacecraft, large equipment such as rockets and manned spacecraft often require specialized protective devices to prevent damage and contamination during transport or during technical preparations for launch. Existing protective covers for large equipment, such as rockets, are typically steel structures with protective towers. These have drawbacks such as the numerous rods, heavy steel material, large footprint, difficulty in land and sea transportation, numerous steel structure nodes, complex assembly and disassembly, and poor sealing of the structure. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the present application provides a protective cover to solve at least one of the above-mentioned technical problems. The specific structure is as follows:

[0005] A protective shield includes a shield body. The shield body includes at least one flexible air fin tube; the at least one air fin tube is provided with at least one air inlet, through which the shield body can be switched between a retracted state and an expanded state; and when in the expanded state, a storage space is formed within the shield body for accommodating a predetermined protection target.

[0006] In some specific embodiments, an air guide port is provided between two adjacent air fin tubes, and an air guide channel is formed between the air inlet and the air guide port; a one-way air intake valve or a two-way air intake valve is provided at the position corresponding to the air guide port between adjacent air fin tubes.

[0007] In some specific embodiments, the air inlet includes a one-way air inlet. When a one-way air inlet valve is provided on the air guide port and the air inlet is a one-way air inlet, at least one air rib tube is provided with at least one air outlet. The air outlet can be provided in the air inlet direction of the one-way air inlet and the one-way air inlet valve, so that the user can quickly inflate or deflate the air rib tube.

[0008] In actual application, adjacent air rib tubes can be fixedly connected by a reinforcement structure. In a specific embodiment, it also includes a fastener provided on the surface of the air rib tube, and the two ends of the reinforcement structure respectively pass through the fasteners at different positions on the surface of the air rib tube to be fixedly connected to the surface of the air rib tube, so as to achieve fixed connection of adjacent air rib tubes. By arranging the reinforcement structure at intervals, adjacent air rib tubes can be fixedly connected, effectively improving the surface tension of the air rib tubes, making the overall structure of the protective cover more stable, and further providing a connection position for the external fixing rope. One end of the external fixing rope is connected to the fastener on the surface of the air rib tube, and the other end is connected to the plane or the ground where the protective cover body is located through a rope tensioning device.

[0009] It should be noted that the present application does not specifically limit the specific number, arrangement direction and arrangement position of the reinforcement structure. For example, in a specific embodiment, multiple reinforcement structures are arranged at intervals along the vertical direction on the surface of the air fin tube to enhance the surface tension of the air fin tube in the vertical direction and the structural strength of the protective cover. Figure 5 Zhongzai Figure 3 The cross-sectional diagram on the bb line is shown.

[0010] In practical applications, the reinforcement structure can also be arranged at intervals on the surface of the gas fin tube by welding. Adjacent gas fin tubes can be fixedly connected by welding. Openings are formed between the welding points of adjacent gas fin tubes. The reinforcement structure passes through the openings to further strengthen the connection between the upper and lower adjacent gas fin tubes. One or more reinforcement structures alternately pass through the openings to be arranged and covered on the surface of the gas fin tube, such as Figure 2 shown.

[0011] In some specific embodiments, the air fin tube is an annular air fin tube, and multiple annular air fin tubes are stacked and arranged along a preset first direction. Under this arrangement, the shape of the protective cover body in the retracted state is more regular, which is more conducive to overall storage.

[0012] In some specific embodiments, the protective cover body further includes a mounting chassis, wherein one or more first positioning connectors are provided on the mounting chassis, and second positioning connectors corresponding to the first positioning connectors are provided on a side of the protective cover body facing the mounting chassis. The second positioning connectors are detachably connected to the first positioning connectors to achieve connection between the protective cover body and the mounting chassis.

[0013] In actual applications, when the preset protection target is a spacecraft, one side of the mounting chassis is used to connect to the external launch pad, and the other side is used to be detachably connected to the protective cover body to further form a closed accommodation space with the interior of the protective cover body.

[0014] In some specific embodiments, the shape of the accommodating space can be consistent with the outer shape of the preset protection target. When the preset protection target is a spacecraft, the outer shape of the preset protection target may show a changing trend from top to bottom, and at least one gradient area is provided on the protective cover body; the projection area of ​​the air fin tube located in the gradient area in the preset first direction continuously shrinks or increases from the bottom to the top of the gradient area.

[0015] In some specific embodiments, at least some adjacent air fin tubes are provided with connecting ports, and a connecting surface is formed between the connecting ports of multiple air fin tubes; the air fin tubes located on one side of the connecting surface can be connected to the air fin tubes located on the other side of the connecting surface in an openable and closable manner.

[0016] In some specific embodiments, a stabilizing and retaining structure is further included, with one end of the stabilizing and retaining structure connected to the air fin tube on one side of the connection surface, and the other end connected to the air fin tube on the other side of the connection surface. By connecting the two ends of the stabilizing and retaining structure to the areas on both sides of the opening and closing structure, the connection between adjacent air fin tubes or the areas on both sides of the opening and closing structure of the air fin tubes can be further stabilized. In practical applications, the stabilizing and retaining structure includes a fixing strap structure.

[0017] In some specific embodiments, the stabilizing and limiting structure can also be used to connect an external fixing rope. One end of the external fixing rope is connected to the stabilizing and limiting structure, and the other end is connected to the plane or ground where the protective cover body is located, which can further stabilize the protective cover body on the placement plane.

[0018] In some specific embodiments, the fastener can also be set on the stable limiting structure, and the fastener is used to connect the external fixing rope. One end of the external fixing rope is connected to the fastener, and the other end is connected to the plane or ground where the protective cover body is located through a rope tensioning device.

[0019] In some specific embodiments, the bottom of the protective cover body is connected to a mounting chassis; it also includes a controller and a sensing detection system; the controller is communicatively connected to the sensing detection system; the sensing detection system is arranged on one or any multiple of the mounting chassis, the inner surface of the protective cover body, and the outer surface of the protective cover body.

[0020] In some specific embodiments, a ventilation system is further included, comprising ventilation channels and ventilation devices. The ventilation channels are disposed on the protective cover body and connect the external atmosphere to the internal storage space of the protective cover body. The ventilation devices are connected to the ventilation channels and are in communication with a controller for adjusting the ventilation of the storage space. In practical applications, the ventilation devices include a fan that effectively exchanges air between the internal storage space of the protective cover and the external atmosphere.

[0021] In some specific embodiments, a lighting system is also included, which includes one or more lighting devices, at least some of which are communicatively connected to a controller; the lighting device is located in the accommodation space, on one or any more of the outer surface of the protective cover body facing the outside world, and the inner surface of the protective cover body facing the accommodation space.

[0022] Beneficial effects: The present application provides a protective shield, comprising a protective shield main body, wherein the protective shield main body comprises at least one flexible air rib tube. By setting an air inlet, the protective shield main body can be switched between a retracted state and an expanded state. A storage space for accommodating a preset protection target is formed in the protective shield main body in the expanded state, which can form an effective protective outer surface layer for the preset protection target. By adopting the flexible air rib tube, the possible signal interference problem when protecting the preset protection target is greatly reduced, and the installation process of the overall protective shield is quick and convenient. The protective shield in the retracted state can be folded, stored and reused, which is more environmentally friendly and can effectively reduce manpower and material resources.

[0042] Example

[0043] This application provides a protective cover, the specific scheme is as follows:

[0044] A protective shield includes a shield body 1. The shield body 1 includes at least one flexible air fin tube 11; at least one air fin tube 11 is provided with at least one air inlet 21, so that the shield body 1 can be switched between a retracted state and an expanded state through the air inlet 21; and when in the expanded state, the shield body 1 has a storage space 3 formed therein for accommodating a predetermined protection target.

[0045] In some specific embodiments, an air inlet 22 is provided between two adjacent air fin tubes 11, and an air guide channel is formed between the air inlet 21 and the air inlet 22. A one-way air inlet valve 221 or a two-way air inlet valve 222 is provided at a position corresponding to the air inlet 22 between adjacent air fin tubes 11. The air inlet 21 includes a one-way air inlet and / or a two-way air inlet.

[0046] In some specific embodiments, the air inlet 21 includes a one-way air inlet. When a one-way air inlet valve is provided on the air guide port 22 and the air inlet 21 is a one-way air inlet, at least one air rib tube 11 is provided with at least one air outlet 23. The air outlet 23 can be provided in the air inlet direction of the one-way air inlet and the one-way air inlet valve, so that the user can quickly inflate or deflate the air rib tube 11.

[0047] In one embodiment, the protective shield body 1 is integrally formed. The user can quickly inflate the protective shield body 1 through the one-way air inlet 21. When the protective shield body 1 needs to be disassembled, the user can quickly deflate the protective shield body 1 through the air outlet 23 or the two-way air outlet, and then fold the deflated protective shield body 1 for storage. Compared to traditional protective devices, the protective shield is smaller and lighter, has multiple functions such as wind, sand, and water resistance, and is low-cost, effectively reducing the manpower and material costs associated with protecting large-scale equipment.

[0048] In some specific embodiments, Figure 2 and Figure 5 As shown, the air fin tube 11 further includes a reinforcement structure 41, which is provided on the surface of the air fin tube 11 to enhance the surface structural strength of the air fin tube 11. In practical applications, the reinforcement structure 41 can be an elastic reinforcement band. By adopting the elastic reinforcement structure 41, the surface strength and elasticity of the air fin tube 11 can be effectively enhanced.

[0049] In practical applications, adjacent air fin tubes 11 can be fixedly connected by a reinforcement structure 41. In a specific embodiment, it also includes a fastener 43 provided on the surface of the air fin tube 11. The two ends of the reinforcement structure 41 pass through the fasteners 43 at different positions on the surface of the air fin tube 11 to be fixedly connected to the surface of the air fin tube 11, and the adjacent air fin tubes 11 are fixedly connected, such as Figure 8 By providing reinforcement structures 41 at intervals, the surface tension of the air fin tube 11 can be effectively increased, making the overall structure of the protective cover more stable and further providing a connection location for the external fixing rope 45. One end of the external fixing rope 45 is connected to the fastener 43 on the surface of the air fin tube 11, and the other end is connected to the plane or ground where the protective cover body 1 is located through a rope tensioning device 44.

[0050] It should be noted that the present application does not specifically limit the specific number, arrangement direction, and arrangement position of the reinforcing structures 41. As long as the surface strength of the air fin tube 11 can be improved, the reinforcing structures 41 can be arranged on the surface of the air fin tube 11 in areas other than the air inlet 21 and / or the air guide port 22. For example, in a specific embodiment, multiple reinforcing structures 41 are arranged on the surface of the air fin tube 11 at intervals along the vertical direction to enhance the surface tension of the air fin tube 11 in the vertical direction and the structural strength of the protective cover. Figure 5 in Figure 3 The cross-sectional diagram on the bb line is shown.

[0051] In practical applications, the reinforcement structure 41 can also be arranged at intervals on the surface of the air fin tube 11 by welding. Adjacent air fin tubes 11 can be fixedly connected by welding. Openings are formed between the welding points of adjacent air fin tubes 11. The reinforcement structure 41 passes through the openings to further strengthen the connection between the upper and lower adjacent air fin tubes 11. One or more reinforcement structures 41 alternately pass through the opening to be arranged and covered on the surface of the air fin tube 11, such as Figure 2 shown.

[0052] In some specific embodiments, the air fin tube 11 is an annular air fin tube 11, and multiple annular air fin tubes 11 are stacked and arranged along a preset first direction. Under this arrangement, the shape of the protective cover body 1 in the retracted state is more regular, which is more conducive to overall storage.

[0053] In some specific embodiments, Figure 6 As shown, it also includes a mounting chassis 5, on which one or more first positioning connectors 511 are provided, and a second positioning connector 512 corresponding to the first positioning connector 511 is provided on the side of the protective cover body 1 facing the mounting chassis 5. Figure 7 The connection between the protective cover body 1 and the mounting chassis 5 is achieved by detachably connecting the second positioning connector 512 to the first positioning connector 511. In practical applications, the first positioning connector 511 and the second positioning connector 512 may include a lock, a magnetic fixing, or the like.

[0054] In a specific embodiment, a placement area 52 and a connection area 51 are provided on the mounting chassis 5. The connection area 51 in the mounting chassis 5 is arranged around the placement area 52. The shape of the placement area 52 is consistent with or larger than the bottom contour of the preset protection target 7. The first positioning connector 511 is located in the connection area 51. Figure 6 shown.

[0055] In actual application, when the preset protection target 7 is a spacecraft, one side of the mounting chassis 5 is used to connect to an external launch platform, and the other side is used to be detachably connected to the protective cover body 1 to further form a closed accommodating space 3 with the interior of the protective cover body 1.

[0056] In some specific embodiments, Figure 1 and Figure 3 As shown, the shape of the accommodating space 3 can be consistent with the shape of the preset protection target 7. When the preset protection target 7 is a spacecraft, the shape of the preset protection target 7 may show a trend of shrinking from top to bottom. In a specific embodiment, at least one gradient area 31 is provided on the protective cover body 1; the projection area of ​​the air fin tube 11 located in the gradient area 31 in the preset first direction shrinks continuously from the bottom to the top of the gradient area 31, which enables the protective cover body 1 to better adapt to the shape and size of the preset protection target. Among them, the preset first direction is as follows Figure 1 Shown in the middle direction A.

[0057] In some specific embodiments, Figure 4 As shown, at least some of the adjacent air fin tubes 11 are provided with connecting ports 12, and a connecting surface 111 is formed between the connecting ports 12 of multiple air fin tubes 11; the air fin tube 11 located on one side of the connecting surface 111 and the air fin tube 11 located on the other side of the connecting surface 111 can be opened and closed for connection.

[0058] In some specific embodiments, Figure 4 As shown, the structure further includes a stabilizing and retaining structure 42, one end of which is connected to the air fin tube 11 on one side of the connection surface 111, and the other end is connected to the air fin tube 11 on the other side of the connection surface 111. By connecting the two ends of the stabilizing and retaining structure 42 to the two side areas of the opening and closing structure, the connection strength of the air fin tubes 11 on both sides of the connection surface 111 can be further stabilized. In actual applications, the stabilizing and retaining structure 42 includes a fixing belt structure.

[0059] In some specific embodiments, the stabilizing and limiting structure 42 can also be used to connect an external fixing rope 45. One end of the external fixing rope 45 is connected to the stabilizing and limiting structure 42, and the other end is connected to the plane or the ground where the protective cover body 1 is located, which can further stabilize the protective cover body 1 on the placement plane.

[0060] In some specific embodiments, the fastener 43 can also be set on the stabilizing limiting structure 42, and the fastener 43 is used to connect the external fixing rope 45. One end of the external fixing rope 45 is connected to the fastener 43, and the other end is connected to the plane or ground where the protective cover body 1 is located through the rope tensioning device 44.

[0061] In some specific embodiments, the bottom of the protective cover body 1 is connected to the mounting chassis 5; it also includes a controller 61 and a sensing detection system 62; the controller 61 is communicatively connected to the sensing detection system 62; the sensing detection system 62 is arranged on one or any multiple of the mounting chassis 5, the inner surface of the protective cover body 1, and the outer surface of the protective cover body 1.

[0062] In practical applications, such as Figure 9 As shown, the sensing detection system 62 may include a contact sensor 623 and a position sensor 624 arranged on the mounting chassis 5, which are used to detect whether the protective cover body 1 and the mounting chassis 5 are tightly connected; it may also include an air pressure detection component 621 arranged on the inner surface or outer surface of the protective cover body 1, which is used to detect whether the air pressure of the air rib tube 11 in the protective cover body 1 is at a normal level; it may also include a temperature and humidity detection component 622 arranged on the inner surface of the protective cover body 1, which is used to detect whether the temperature and humidity of the accommodating space 3 inside the protective cover body 1 are in line with normal levels. It can detect the protective cover as a whole from various aspects, and promptly feedback the detection results to the user through the controller 61.

[0063] In some specific embodiments, a ventilation system 63 is further included, comprising a ventilation channel 631 and a ventilation device 632. The ventilation channel 631 is disposed on the protective cover body 1 and connects the external atmosphere to the accommodation space 3 within the protective cover body 1. The ventilation device 632 is connected to the ventilation channel 631 and is communicatively connected to the controller 61 to adjust the ventilation of the accommodation space 3. In actual use, the ventilation device 632 includes a fan that can effectively exchange air between the accommodation space 3 within the protective cover and the external atmosphere, keeping the air in the accommodation space 3 fresh and unobstructed.

[0064] In some specific embodiments, a lighting system 64 is further included. The lighting system 64 includes one or more lighting devices 641, at least some of which are communicatively connected to the controller 61. The lighting devices 641 are located in the receiving space 3, on one or more of the outer surface of the protective cover body 1 facing the outside, and on the inner surface of the protective cover body 1 facing the receiving space 3. The lighting system 64 can provide supplementary lighting when the light inside the receiving space 3 and outside the protective cover is insufficient.

[0065] In actual application, the user can remotely control the lighting system 64 and the ventilation system 63 through the controller 61, and quickly obtain the installation status between the mounting chassis 5 and the protective cover body 1 to achieve remote control of the protective cover body 1.

[0066] In a specific application process, the user can first place the mounting chassis 5 in the corresponding area. For example, when the preset protection target 7 is a spacecraft, the mounting chassis 5 can be placed on the launch pad; then the preset protection target 7 is moved onto the mounting chassis 5, and the first positioning connector 511 on the mounting chassis 5 is connected to the second positioning connector 512 provided at the bottom of the protective cover for connection with the mounting chassis 5. At this time, the protective cover can be placed on the preset protection target 7. Furthermore, the present application does not limit the specific installation time of the protective cover and the installation order between the various components. As long as the preset protection target 7 can be located in the accommodation space 3 inside the protective cover and the protective cover is tightly connected to the mounting chassis 5, the protective cover can be inflated first and then hoisted to the position corresponding to the mounting chassis 5, or the protective cover can be pre-hoisted to the position where the mounting chassis 5 is located, and then inflated after being connected to the mounting chassis 5. There are many different installation methods, which can be arranged from different aspects.

[0067] This embodiment provides a protective shield, including a protective shield body, which includes at least one flexible air fin tube. By providing an air inlet, the protective shield body can be switched between a retracted state and an expanded state. A storage space for accommodating a preset protection target is formed within the protective shield body in the expanded state, thereby forming an effective protective outer layer for the preset protection target. By using flexible air fin tubes, the potential signal interference problem when protecting the preset protection target is greatly reduced. Furthermore, the overall protective shield is lightweight, has a good isolation effect, and is quick and convenient to install. In the retracted state, it can be quickly folded, stored, and reused, making it more environmentally friendly and saving a significant amount of manpower and material resources.
