Description

Technical Field

[0001] The present application relates to the field of air membranes, and in particular to an air membrane device for lightning protection. Background Art

[0002] Air film equipment is a structural system that uses membrane material as the outer shell, and provides positive air pressure inside the membrane material shell by equipping the shell with intelligent electromechanical equipment, thereby providing support for the shell. Air film equipment has a wide range of applications in various fields due to its flexible use, short construction period, low requirements for construction foundation, and low cost. However, due to the flexible surface characteristics of the air film, for the safety needs of lightning protection, air film equipment always has problems such as difficulty in setting up and installing lightning arresters. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the present application provides a lightning protection air film device to solve at least one of the above-mentioned technical problems. The specific structure is as follows:

[0004] A lightning protection air film device includes an air film, a steel cable and a conductive connector, wherein a plurality of steel cables cross the outer surface of the air film to form a cable net system for limiting the shape of the air film, a plurality of cross points are formed on the cable net system, and the outer surface of the steel cables is covered with an insulating layer.

[0005] The conductive connector is located at some intersections and connects at least two steel cables. A protrusion is provided in the conductive connector, which is used to fix and squeeze the steel cables under the pressure of the outer surface of the air film, thereby reducing the thickness of the insulating layer of the steel cables in the conductive connector, so that the crossed steel cables in the conductive connector form a conductive structure and conduct each other; wherein grounding wires extend from both ends of the steel cables, and the grounding wires are directly or indirectly grounded.

[0006] The present application uses a conductive connector to fix different steel cables in the cable net system on the outer surface of the air membrane. Since the air membrane material is fully inflated by inflation, the cable net system and the conductive connector will be tightly connected to the outer surface of the air membrane. Since the conductive connector is provided with a protrusion inside, under the tightening effect of the conductive connector itself and the pressure of the external air membrane bulging, the insulating layer of the steel cable in the conductive connector will be squeezed and thinned, so that the mutually contacting steel cables in the conductive connector form a structure that can be mutually conductive, thereby forming electrical penetration. The conductive connector and the steel cables crossed in the conductive connector form a lightning arrester. During use, the lightning strike can be directed to the ground through the grounding wire in the steel cable, thereby enabling the air membrane equipment to meet the lightning protection requirements.

[0007] In actual applications, the interior of the steel cable is a steel bundle, and the outer surface of the steel cable is covered with an insulating layer of a polyethylene protective layer, wherein the thickness of the polyethylene protective layer ranges from 1.5 to 2.0 mm. In actual practice, for conventional 16# and below steel cables, the polyethylene protective layer thickness is 1.5 mm; for 18# and above steel cables, the polyethylene protective layer thickness is 2.0 mm. In one embodiment, the height of the protrusion in the conductive connector ranges from 1.5 to 2.0 mm. When the protrusion is tightened to the steel cable, the thickness of the polyethylene protective layer on the steel cable can be reduced to 0 to 0.5 mm, so that this part of the steel cable can be conductive.

[0008] In some specific embodiments, the cable net system is divided into a preset lightning strike zone and a preset safety zone; the lightning strike zone at least covers the top of the outer surface of the air film. Among them, the installation density of the conductive connectors in the lightning strike zone is higher than the installation density of the conductive connectors in the safety zone. In practical applications, the installation density of the conductive connectors refers to the ratio of the number of intersections in the area where the conductive connectors are installed to the total number of intersections in the area. It should be noted that the present application does not limit the total number and number ratio of conductive connectors installed in the cable net system. The user can divide the lightning strike zone and the safety zone according to the actual situation, and determine whether the conductive connectors need to be installed at the intersections of the steel cables in the cable net system according to the actual situation.

[0009] In practical applications, there are many installation and arrangement rules for conductive connectors. A conductive connector may be installed at every intersection on a steel cable to form a densely arranged layout; or a conductive connector may be installed at every one or more intersections, and the conductive connectors on multiple steel cables may be staggered to form a plum blossom-shaped layout.

[0010] In some specific embodiments, the conductive connector includes a first clip and a second clip. The first clip is provided with a first through slot, and the second clip is provided with a second through slot.

The two steel cables pass through the first through slot and the second through slot respectively and are mutually conductive in the conductive connector.

[0011] In a specific embodiment, the first buckle and the second buckle in the conductive connector can form a cross buckle, wherein the first through slot is arranged perpendicular to the second through slot, so that the two steel cables in the conductive connector can be perpendicular to each other.

[0012] In some specific embodiments, at least one reinforcing rib is disposed on the outer surface of the conductive connector to improve the strength of the conductive connector itself and the connection strength of the steel cable in the conductive connector.

[0013] In some specific embodiments, each edge of the conductive connector is rounded and chamfered to reduce damage to the outer surface of the air film caused by the conductive connector.

[0014] In some specific embodiments, a retaining wall is further included, and both ends of the steel cable are fixedly connected to the retaining wall. A pre-buried conductor is arranged at the retaining wall, and both ends of the steel cable are connected to the retaining wall. The steel cable is connected to the pre-buried conductor through a grounding wire to ground the cable net system.

[0015] In practical applications, the retaining wall is a concrete retaining wall used to fix the air membrane.

[0016] In some specific embodiments, the embedded conductor includes a lightning protection metal mesh and a conductive member, the lightning protection metal mesh is located in the retaining wall, one end of the conductive member is connected to the lightning protection metal mesh, and the other end is exposed from the retaining wall and connected to the ground wire. In practical applications, the lightning protection metal mesh can be a steel mesh.

[0017] In some specific embodiments, a metal fixing is connected to the upper surface of the retaining wall, the embedded conductor portion is exposed from the retaining wall and fixedly connected to the metal fixing, and the grounding wire is connected to the metal fixing.

[0018] In some specific embodiments, at least part of the grounding wire is connected to the embedded conductor via a connecting metal fixture.

[0039] Example

[0040] The present application provides an air film device for lightning protection. The specific structure is as follows Figure 1 to Figure 7 The specific plan is as follows:

[0041] A lightning protection air film device comprises an air film 1, a steel cable 2 and a conductive connector 3. A plurality of steel cables 2 cross the outer surface of the air film 1 to form a cable net system for limiting the shape of the air film 1, a plurality of intersections are formed on the cable net system, and an insulating layer 21 is coated on the outer surface of the steel cables 2.

[0042] The conductive connector 3 is located at some intersections and connects at least two steel cables 2. A protrusion 33 is provided in the conductive connector 3. The protrusion 33 is used to fix and squeeze the steel cables 2 under the pressure of the outer surface of the air film 1, which can reduce the thickness of the insulating layer 21 of the steel cables 2 in the conductive connector 3, so that the crossed steel cables 2 in the conductive connector 3 form a conductive structure and conduct with each other, such as Figure 2-3 As shown. Among them, grounding wires 22 extend from both ends of the steel cable 2, as shown in FIG. Figure 7 In practical applications, the grounding wire 22 is directly or indirectly grounded.

[0043] The present application fixes different steel cables 2 in the cable net system on the outer surface of the air film 1 by using the conductive connector 3. Since the air film material is fully inflated by inflation, the cable net system and the conductive connector 3 will be tightly connected to the outer surface of the air film 1. Since the conductive connector 3 is provided with a protrusion 33 inside, under the tightening effect of the conductive connector 3 itself and the pressure of the external air film 1 swelling, the insulating layer 21 of the steel cable 2 in the conductive connector 3 will be squeezed and thinned, so that the mutually contacting steel cables 2 in the conductive connector 3 form a structure that can be mutually conductive, thereby forming electrical penetration. The conductive connector 3 and the steel cables 2 crossed in the conductive connector 3 form a lightning arrester. During use, the lightning strike can be directed to the ground through the grounding wire 22 in the steel cable 2, thereby enabling the air film equipment to meet the lightning protection requirements.

[0044] In actual applications, the interior of the steel cable 2 is a steel bundle, and the outer surface of the steel cable 2 is covered with an insulating layer 21 which is a polyethylene protective layer, wherein the thickness of the polyethylene protective layer ranges from 1.5 to 2.0 mm. In actual practice, for conventional 16# and below steel cables 2, the polyethylene protective layer thickness is 1.5 mm; for 18# and above steel cables 2, the polyethylene protective layer thickness is 2.0 mm. In one embodiment, the height of the protrusion 33 in the conductive connector 3 ranges from 1.5 to 2.0 mm. When the protrusion 33 is fastened to the steel cable 2, the thickness of the polyethylene protective layer on the steel cable 2 can be reduced to 0 to 0.5 mm, so that this part of the steel cable 2 can be conductive.

[0045] In a specific embodiment, the protrusion 33 can be a transverse convex line similar to threaded steel, and multiple protrusions 33 are arranged in the first through groove 311 and the second through groove 321, so that the protrusion 33 can not only squeeze the insulating layer of the steel cable 2, but also further increase the friction between the conductive connector 3 and the steel cable 2, so that the conductive connector 3 has a stronger tightening effect on the steel cable 2.

[0046] In some specific embodiments, the cable net system is divided into a preset lightning strike zone and a preset safety zone; the lightning strike zone at least covers the top of the outer surface of the air membrane 1. Among them, the installation density of the conductive connectors 3 in the lightning strike zone is higher than the installation density of the conductive connectors 3 in the safety zone. In practical applications, the installation density of the conductive connectors 3 refers to the ratio of the number of intersections in which the conductive connectors 3 are installed in the area to the total number of intersections in the area. It should be noted that the present application does not limit the total number and number ratio of conductive connectors 3 installed in the cable net system. The user can divide the lightning strike zone and the safety zone according to the actual situation, and determine whether the conductive connectors 3 need to be installed at the intersections of the steel cables in the cable net system according to the actual situation.

[0047] In practical applications, there are also various installation and arrangement rules for the conductive connectors 3. The conductive connectors 3 may be installed at each intersection on a steel cable 2 to form a densely arranged layout, such as Figure 1 A region layout is shown; it is also possible to install a conductive connector 3 at each one or more intersections, and the conductive connectors 3 on the multiple cables 2 are staggered to form a plum blossom-shaped layout, such as Figure 1 The layout of area B is shown in the figure.

[0048] In some specific embodiments, the conductive connector 3 includes a first latch 31 and a second latch 32. The first latch 31 is provided with a first through slot 311, and the second latch 32 is provided with a second through slot 321. The protrusion 33 is located in the first through slot 311 and the second through slot 321. Figure 4The first snap fastener 31 and the second snap fastener 32 are arranged opposite to each other and fixedly connected by the connecting member 36, and the first through slot 311 is not parallel to the second through slot 321. The two steel cables 2 pass through the first through slot 311 and the second through slot 321 respectively and are connected to each other in the conducting connector 3.

[0049] In a specific embodiment, the first buckle 31 and the second buckle 32 in the conductive connector 3 can form a cross buckle, wherein the first through slot 311 is arranged perpendicular to the second through slot 321, so that the two steel cables 2 in the conductive connector 3 can be perpendicular to each other. In practical applications, the first buckle 31 and the second buckle 32 can be two identical one-line buckles with symmetrical structures, and mutually symmetrical connecting ports 35 are arranged at both ends of the one-line buckle, so that when the first buckle and the second buckle are arranged opposite to each other, and the first through slot 311 of the first buckle and the second through slot 321 of the second buckle are arranged perpendicular to each other, the connecting ports 35 of the two can also correspond to each other, and finally form a cross buckle, such as Figure 6 In a specific embodiment, the connecting member 36 is a bolt, and the first buckle and the second buckle can be connected to form a cross buckle by screwing the bolt into the connecting openings 35 corresponding to the first buckle and the second buckle, as shown in FIG. Figure 3 and Figure 6 shown.

[0050] In some specific embodiments, at least one reinforcing rib 34 is disposed on the outer surface of the conductive connector 3 to improve the strength of the conductive connector 3 itself and the connection strength of the steel cable 2 in the conductive connector 3. Figure 4-5 As shown, four reinforcing ribs 34 may be symmetrically arranged on the conductive connector 3 .

[0051] In some specific embodiments, each edge of the conductive connector 3 is rounded and chamfered to reduce damage to the outer surface of the air membrane 1 caused by the conductive connector 3 .

[0052] In some specific embodiments, a retaining wall 4 is further included, wherein both ends of the steel cable 2 are fixedly connected to the retaining wall 4, a pre-buried conductor is provided at the retaining wall 4, both ends of the steel cable 2 are connected to the retaining wall 4, and the steel cable 2 is connected to the pre-buried conductor via a grounding wire 22, so that the cable network system is grounded. The pre-buried conductor includes a lightning protection metal mesh 41 and a conductive member 42, wherein the lightning protection metal mesh 41 is located in the retaining wall 4, one end of the conductive member 42 is connected to the lightning protection metal mesh 41, and the other end is exposed from the retaining wall 4 and connected to the grounding wire 22.

[0053] In some specific embodiments, at least part of the grounding wire is connected to the embedded conductor via the connecting metal fixing piece 5 .

[0054] In some specific embodiments, a metal fixing 5 is connected to the upper surface of the retaining wall 4, the embedded conductor part is exposed from the retaining wall 4 and fixedly connected to the metal fixing 5, and the grounding wire 22 is connected to the metal fixing 5. In some specific embodiments, the metal fixing 5 is a galvanized angle steel, and the conductive member 42 is a screw rod, which is arranged perpendicular to the lightning protection metal mesh 41, one end of the screw rod is connected to the lightning protection metal mesh 41, and the other end is exposed from the upper surface of the concrete retaining wall and connected to the galvanized angle steel.

[0055] Furthermore, a steel cable joint 23 is provided at one end of the steel cable 2 connected to the retaining wall 4 , one end of the grounding wire is connected to the steel cable joint 23 , and the other end is connected to the metal fixing piece 5 .

[0056] In some specific embodiments, the metal fixing part 5 may also be a cable embedded part. In some cable net systems with larger spans, the steel cable joint 23 may be connected to the cable embedded part, wherein the grounding wire is connected to the cable embedded part.

[0057] In an actual application process, when the cable net system is struck by lightning, the electricity generated by the lightning strike will be quickly introduced into the conductive connector 3 in the cable net system that is closest to the lightning strike point. The current enters the steel cables 2 crossing in the conductive connector 3 through the conductive connector 3, and is introduced into the earth through the grounding wire 22 extending from the end of the steel cables 2, or is further dispersed and introduced into other steel cables 2 through other conductive connectors 3, and then introduced into the earth through the grounding wire 22 at the end of the steel cables 2.

[0058] The retaining wall 4 is a concrete retaining wall for fixing the air film 1. The concrete wall is connected to the ground. A lightning protection metal mesh 41 and a screw are embedded in the concrete wall. The upper part of the screw is exposed and enters the galvanized angle steel provided on the upper surface of the retaining wall 4 and is fixedly connected to the angle steel. In practical applications, the lightning protection metal mesh 41 can be a steel mesh.

[0059] In the process of conducting electricity into the earth, since a steel cable joint 23 is also provided at the end of the steel cable 2, the grounding wire 22 at the end of the steel cable 2 is connected to the steel cable joint 23. The steel cable joint 23 and the grounding wire 22 on the steel cable 2 are further connected to the pressed galvanized angle steel provided on the upper surface of the retaining wall 4. Since the angle steel has a conductive property and the angle steel is actually connected to the lightning protection metal mesh 41 in the concrete wall through a screw rod, the current can be conducted into the earth through the sequence of steel cable 2-grounding wire 22-steel cable joint 23-angle steel-screw rod-lightning protection metal mesh 41, so that the air film device in the present application finally realizes the lightning protection function of protecting the air film 1 and conducting lightning strikes into the earth.

[0060] This embodiment provides a lightning protection air film device, which connects the crossed steel cables in the cable net system by setting a conductive connector, and uses the squeezing force of the outer surface of the air film on the steel cables to reduce the thickness of the insulating layer on the surface of the steel cables in the conductive connector, so that the intersections between the steel cables can be mutually conductive to form a conductive structure, and together with the conductive connector, form a lightning receptor, which is further grounded. The connection structure of this lightning receptor is simpler and easier to install, and a simpler grounding structure is used, which can effectively achieve the safety effect of lightning termination and lightning protection.

[0061] When the portion of the steel cable other than the intersection can be made a safe insulator, the intersections between the steel cables can be connected to each other and form a lightning rod together with the conductive connector. The connection structure of this lightning rod is simpler and easier to install. It also uses a simpler grounding structure, which can effectively achieve the safety effect of lightning termination and lightning protection.
