Description

Technical Field

[0001] The present invention relates to a simple installation type lightning strike suppression device for protecting an object to be protected from lightning damage by suppressing lightning strikes, and is capable of being moved to a desired location.

Background Art

[0002] In the protection of infrastructure and the like against lightning strikes, in the conventional lightning protection concept, from the viewpoint that lightning strikes cannot be prevented, most of the methods are to receive lightning strikes by a pointed lightning rod (Franklin rod) and conduct them to the ground. In contrast, the present inventors have proposed a lightning strike suppression device shown in Patent Document 1 in order to protect an object to be protected by suppressing the occurrence of lightning strikes as much as possible.

[0003] This lightning strike suppression device has an inner electrode body and an outer electrode body having a spherical shell shape with the same center point with an insulator interposed therebetween, and is configured by grounding only the inner electrode.

[0004] Then, for example, when a thundercloud with negative charges distributed at the cloud base approaches, opposite charges (positive charges) are distributed on the surface of the ground, and positive charges also accumulate on the grounded inner electrode body. Then, the outer electrode body arranged via the insulator becomes negatively charged due to the action of a capacitor. By this action, the occurrence of upward streamers in and around the lightning protection device is made difficult, and the occurrence of lightning strikes is suppressed.

[0005] In the installation work of the lightning strike suppression device shown in Patent Document 1, when installing using an existing building, fixing work of columns to the building is required, and when using a newly constructed support structure, construction work of the support structure and fixing work of columns to the support structure are required. Furthermore, in any case, laying work of a grounding wire for grounding the electrode body is further required. In addition, the installation position is also restricted by the position of the building or the support structure, and further, since the removal work is complicated, it becomes almost a permanent structure after installation.

[0006] In addition, the infrastructure to be protected from lightning strikes is not limited to buildings, but also includes vehicles parked outdoors and electrical products such as computers. Thus, due to the fact that the objects to be protected by a lightning strike suppression device are inherently those that use electricity regardless of whether they are movable or immovable property, a lightning strike suppression device that can be easily installed outside buildings has come to be desired.

[0007] In response to such problems, the inventors proposed a lightning strike suppression device shown in Patent Document 2. This lightning strike suppression device is provided with a base body that can be connected to the rear of an automobile and moved as a trailer, and at the destination, a support column and the lightning strike suppression device main body are assembled to enable lightning strike countermeasures at any location.

Summary of the Invention

Problems to be Solved by the Invention

[0009] With the lightning strike suppression device described in Patent Document 2, the flexibility in lightning strike countermeasures has been improved, such as installing the lightning strike suppression device in accordance with the aircraft parking location at the airport. However, since this lightning strike suppression device is large, it requires towing by an automobile for movement, and even when not in use, it occupies a large amount of space.

[0010] In addition to the above, in the transportation of the lightning strike suppression device, methods such as stacking on the truck bed or manually holding it are also considered. Also, considering the need to have a configuration for installation separate from the wheels, the configuration of the base body with permanent wheels was inefficient from the viewpoints of handling, equipment costs, and the number of parts.

[0011] In view of the above problems, an object of the present invention is to provide a simple installation type lightning strike suppression device that can be manufactured at a lower cost, suppress the occupied space, can be easily moved and installed manually, and can stably maintain the grounding state.

With such a configuration, it is possible to achieve a lower cost, suppress the occupied space, easily move and install the lightning strike suppression device manually, and stably maintain the grounding state.

[0013] In a preferred form of the present invention, the frame further includes an adjustment member capable of expanding the contact area between the grounding portion and the ground. With such a configuration, it is possible to easily cope with the unevenness of the ground on which the frame is grounded and make the grounding state of the lightning strike suppression device more stable.

With such a configuration, it is possible to easily secure the electrical connection area between the frame and the ground with a small number of parts.

[0016] In a preferred form of the present invention, the frame has a protruding portion protruding in the height direction. With such a configuration, when not in use, multiple frames can be stacked and stored, and they can also be easily carried out.

[0017] In a preferred form of the present invention, the frame has a support mounting portion, and a rotatable joint portion is provided on the support mounting portion. With such a configuration, the support with the lightning strike suppression device main body mounted thereon can be easily erected.

[0018] In a preferred form of the present invention, the joint portion is provided so as to be rotatable about a horizontal axis. With such a configuration, the lightning strike suppression device main body can be easily erected, and in addition, when removing, the direction of tipping is determined, and safety can be easily ensured.

[0019] In a preferred form of the present invention, it further includes a moving mechanism having a rotating shaft, and the frame further has a mounting portion capable of temporarily fixing the moving mechanism. With such a configuration, the lightning strike suppression device can be easily moved and installed manually.

[0020] In a preferred form of the present invention, the mounting portion is provided with a concave portion that fits with a part of the moving mechanism. With such a configuration, the moving mechanism can be easily attached and detached, and the conveyance and grounding of the frame can be easily switched.

[0021] In a preferred form of the present invention, the mounting portion is provided with a shaft joint portion that allows the moving mechanism to rotate about a horizontal axis. With such a configuration, the moving mechanism can be easily rotated, and the conveyance and grounding of the frame can be easily switched.

[0022] In a preferred form of the present invention, a plurality of the moving mechanisms are attached to the frame, and at least one of the moving mechanisms has a rudder portion that can rotate about a vertical axis. With such a configuration, it is possible to easily change the traveling direction even manually when transporting the frame body.

[0023] The invention of the present application for solving the above problems includes an accommodating step of accommodating a lightning strike suppression device main body constituting a main part of lightning strike suppression and a support body for supporting the lightning strike suppression device main body at a predetermined height in a frame body capable of standing and transporting the support body, a transporting step of transporting the frame body in which the lightning strike suppression device main body and the support body are accommodated to an installation location, a grounding step of grounding the frame body, and a supporting step of standing and fixing the support body on which the lightning strike suppression device main body is mounted to the frame body to support the lightning strike suppression device main body at a predetermined height, which is an installation method of a simple installation type lightning strike suppression device. By such a method, it is possible to move and install the lightning strike suppression device more inexpensively, with a reduced occupied space, easily by manual labor, and further stably maintain the grounding state.

[0024] In a preferred form of the present invention, the grounding step includes a ground contact area expansion step of expanding the electrical contact area between the lower surface of the frame body and the ground using an adjustment member whose length can be adjusted in the height direction.

Embodiments for Carrying Out the Invention

[0028] Hereinafter, the simple installation type lightning strike suppression device X according to each embodiment of the present invention will be described with reference to the drawings. The description will be detailed in the order of the configuration of the embodiment, the method of implementation, and other examples. Note that each of the embodiments shown below is an example of the present invention, and the present invention is not limited to the following embodiments.

[0029] ≪First Embodiment≫ The simple installation type lightning strike suppression device X according to the present embodiment is, as shown in Fig. 1(a), Fig. 1(b) or Fig. 7(b), a lightning strike suppression device main body 1, a support 2 that supports the lightning strike suppression device main body 1 at a predetermined height, a frame 3 that can be erected and transported to a predetermined location, and a moving mechanism 4 that can be attached to the frame 3. Further, the "height direction" in the following description is the direction of the coordinate axis shown in each drawing, and any direction in a plane perpendicular to the "height direction" is taken as the horizontal direction.

[0030] Here, the content shown in each drawing will be described in detail.

FIG. 4 is a cross-sectional view showing the configuration of the lightning strike suppression device main body 1 according to the present embodiment. FIG. 5 is a schematic view when the lightning strike suppression device main body 1, the support body 2, and the frame body 3 are prepared in the installation of the simple installation type lightning strike suppression device X according to the present embodiment. FIGS. 6(a) and 6(b) are schematic views showing the state during the installation or disassembly of the simple installation type lightning strike suppression device X according to the present embodiment, and FIGS. 7(a) and 7(b) are schematic views showing the state in which the simple installation type lightning strike suppression device X is installed.

[0031] Here, regarding the form of the simple installation type lightning strike suppression device X shown in the drawings, those shown from FIG. 2 and later conform to FIG. 1(b) for the purpose of explanation, but it is also possible to appropriately convert to the form conforming to FIG. 1(a). This also applies mutatis mutandis to the description of other embodiments.

[0032] The lightning strike suppression device main body 1 is a device that constitutes the main part of the simple installation type lightning strike suppression device X. As shown in FIG. 4, it includes a first electrode body 11 formed in a substantially spherical or substantially spherical shell shape by a conductive material, and a second electrode body 12 formed in a substantially concentric spherical shell shape with a predetermined gap from the first electrode body 11 (which may be divided into two parts, a ground side electrode structure body 121 and a tip side electrode structure body 122, or may be integrally formed). It also has a connection post 13 made of a conductive material that supports the first electrode body 11 and is connectable to the ground G, and a spacer 14 made of an insulating material that maintains the gap between the first electrode body 11 and the second electrode body 12 and supports the second electrode body 12.

[0033] The lightning strike suppression device main body 1 is connected to a support 2, particularly a main support post 21 (described later), by the connection post 13. From the first electrode body 11, the connection post 13, the support 2, and the frame body 3 are all composed of conductive members and assembled into an electrically connected configuration, so that the first electrode body 11 is grounded, the lightning strike suppression device main body 1 generates the action of a capacitor, and the occurrence of lightning strikes is suppressed.

[0034] The support 2 has a main support post 21 that supports the lightning strike suppression device main body 1 at a predetermined height in the height direction, an auxiliary support post 22 that assists to prevent the main support post 21 from falling, and a suspension post 23 used for work when installing the lightning strike suppression device main body 1.

[0035] The main support post 21 is made of a conductive material and, as shown in FIGS. 5, 6(a), 6(b), 7(a), and 7(b), is a plurality of columnar members. By connecting these in series in the length direction, a predetermined height required for the installation of the lightning strike suppression device main body 1 is obtained, and it is further erected on the frame body 3. In the drawings, the main support post 21 is shown in a form composed of three, but the number may be different as long as a predetermined height can be obtained. Also, although omitted in the drawings, the connection between the main support posts 21 is, for example, by a configuration in which flanges or stepped portions provided at the ends are fixed by bolt fastening.

[0036] Among the plurality of main support columns 21, it is preferable that at least one main support column 21 is configured to be provided with a connection flange 211. The connection flange 211 is a flat plate-like member that enlarges the cross-section of the main support column 21, and is provided with an auxiliary support column 22 and an attachment portion to which a working wire W can be attached, which will be described later. With such a configuration, components around the main support column 21 can be easily attached.

[0037] The auxiliary support column 22 is a columnar member that holds the main support column 21 in an erected state. As shown in FIG. 7(b), in the middle of the main support column 21, particularly from the connection flange 211, it is connected in a plurality of diagonal directions toward the frame body 3 to form a cone and support the main support column 21.

[0038] As shown in FIGS. 6(a), 6(b), and 7(a), the suspension support column 23 is a columnar member that is erected obliquely from the frame body 3 at a predetermined elevation angle, and is provided so as to move away from the erected position of the main support column 21 as it goes upward in the height direction. Further, the suspension support column 23 is provided with a pulley 231 at its tip. With such a configuration, by hanging the wire W attached to the connection flange 211 on the pulley 231 and pulling the wire W, the main support column 21 can be easily lifted.

[0039] The frame body 3 is a base frame portion of a conveying means that enables the lightning strike suppression device main body 1 and the support body 2 to be conveyed to a desired location (installation location), and includes a standing frame 31, a bottom plate 32, a main support column attachment portion 33, a suspension support column attachment portion 34, a winch 35, a protruding portion 36, and a moving mechanism attachment portion 37. Thereby, the lightning strike suppression device is made mobile.

[0040] As shown in FIG. 1(a) or FIG. 1(b), the standing frame 31 is a frame member that forms the peripheral edge of the frame body 3 and gives weight. With such a configuration, the strength of the frame body 3 is improved, and the conveyance to the installation location is facilitated and made safe. Also, by increasing the weight of the peripheral edge portion, when the frame body 3 is placed on the ground G, the followability to slight unevenness of the ground G is increased, and it can contact the ground G more stably, and a more stable grounding state can be maintained as a grounding portion.

[0041] The vertical frame 31 of this embodiment is a member that protrudes from the frame body 3 in height and determines the overall size and shape. Also, as shown in Fig. 1(a), the vertical frame 31 is formed by combining H-shaped steel materials (other metal materials, such as combinations of metal beams, metal plates, L-shaped steel materials, square tubular steel materials, etc.) to form a substantially rectangular shape in the horizontal direction. By using H-shaped steel, the weight of the frame body 3 increases compared to a combination of metal plates, so that the frame body 3 can be grounded more stably.

[0042] The bottom plate 32 is a flat plate-shaped member that closes a part or all of the lowermost surface of the vertical frame 31. It is treated as a grounding part that can ground the lightning strike suppression device main body 1, and together with the vertical frame 31 and the bottom plate 32, a receiving box-shaped accommodation part 311 is formed. Thereby, the lightning strike suppression device main body 1 and the support body 2 are accommodated in the frame body 3. With such a configuration, all the components of the simple installation type lightning strike suppression device X can be easily transported to a desired location.

[0043] It is preferable that the vertical frame 31 is not only the outer frame that determines the outer shape of the frame body 3, but also further provided at several locations so as to partition the inside. With such a configuration, it is possible to reinforce particularly parts where the load is concentrated in the frame body 3, such as the main support column attachment part 33 and the hoisting machine 35.

[0044] As shown in Fig. 3(b), the main support column attachment part 33 is a support body attachment part provided at a substantially central part in the horizontal direction of the frame body 3, and is provided with an insertion part 331 for inserting and supporting the main support column 21, a movable bottom plate 332 that closes the bottom of the insertion part 331, and a standing shaft joint part 333 that enables the insertion part 331 and the movable bottom plate 332 to rotate. With such a configuration, the horizontal width of the frame body 3 formed by the vertical frame 31 and the bottom plate 32 can be effectively used in supporting the lightning strike suppression device main body 1 and the support body 2.

[0045] The insertion part 331 is a cylindrical member capable of inserting the main support column 21 and standing it up and supporting it in the height direction, and is provided with ribs for reinforcing the connection part with the movable bottom plate 332. The movable bottom plate 332 is a flat plate member that closes the bottom of the insertion part 331 and further expands, and is rotatably connected to the standing frame 31 or the bottom plate 32 via the vertical shaft joint part 333. Here, the movable bottom plate 332 can be in surface contact with the upper surface of the frame body 3 or the upper surface of the standing frame 31. With such a configuration, when the support body 2 connected to the lightning strike suppression device main body 1, particularly the main support column 21, is lifted and erected, the rotation of the vertical shaft joint part 333 is stopped by the movable bottom plate 332, preventing the operation of lifting the support body 2 from going too far and falling to the opposite side, so that the installation work of the simple installation type lightning strike suppression device X can be carried out safely. Also, when withdrawing the simple installation type lightning strike suppression device X, since the main support column 21 falls only in one direction, it is easier to ensure safety during the operation.

[0046] The vertical shaft joint part 333 is a joint (hinge joint) that can rotate about the axis in the horizontal direction, enabling the insertion part 331 and the movable bottom plate 332 to rotate from the horizontal direction to the height direction. Preferably, as shown in FIGS. 6(a), 6(b), and 7(a), the insertion part 331 is configured to fall facing the longitudinal side of the frame body 3, in other words, the axis of rotation is oriented parallel to the short side of the frame body 3. With such a configuration, the fluctuation of the load generated when the lightning strike suppression device main body 1 and the main support column 21 are erected or laid down can be received throughout the longitudinal direction of the frame body 3, and the work can be carried out more safely.

[0047] The vertical frame 31, the bottom plate 32, and the main support column attachment part 33 are made of conductive materials. With such a configuration, when the support 2 with the lightning strike suppression device body 1 mounted thereon is connected, an electrical connection is established from the first electrode body 11 to the bottom plate 32. Further, at this time, by bringing the bottom plate 32 into contact with the ground G (such as concrete or soil) that can be grounded, the first electrode body 11 can be easily grounded. Also, with the entire horizontal size of the frame body 3, and all the weights of the lightning strike suppression device body 1, the support 2, and the frame body 3, the conductive part can be pressed against the ground G, and the grounding state of the simple installation type lightning strike suppression device X can be easily stabilized. Therefore, even under conditions where it is not possible to dig a hole in the ground G and bury a grounding wire (such as an airport apron, concrete paving, etc.), the lightning strike suppression device body 1 can be surely grounded.

[0048] The suspension support column attachment part 34 is provided adjacent to the main support column attachment part 33, and is composed of a cylindrical member that inserts and supports the suspension support column 23, and a flat rib that reinforces the connection part with the vertical frame 31 or the bottom plate 32. In particular, as shown in FIGS. 3(b) and 6(a), the direction of the cylinder is provided so as to support the suspension support column 23 in an inclined direction and with its tip farthest from the main support column 21. With such a configuration, as shown in FIGS. 6(a), 6(b), and 7(a), the main support column 21 can be easily erected using the wire W.

[0049] The winch 35 is a device for winding or pulling out the wire W, and as shown in FIGS. 1(a) and 1(b), it is provided on the vertical frame 31 or the bottom plate 32 on the side opposite to the main support column attachment part 33 with respect to the suspension support column attachment part 34. With such a configuration, as shown in FIGS. 6(a), 6(b), and 7(a), not only can the wire W be wound to easily erect the main support column 21, but also the work can be done more safely when the main support column 21 is toppled.

[0050] As shown in FIGS. 1(a), 1(b), 2(a), and 2(b), the protruding portion 36 is a columnar member that protrudes in the height direction (upward) in the frame body 3, and its protruding height is higher than that of any other component provided in the upper part of the frame body 3, such as the vertical shaft joint portion 333, the suspension support attachment portion 34, and the hoist 35. With such a configuration, as shown in FIG. 3(c), when the frame bodies 3 in the non-use state are stacked vertically, the protruding portion 36 of the lower frame body 3 receives the bottom plate 32 of the upper frame body 3, so that a gap that can be easily loaded and unloaded by a forklift can be secured while maintaining stability.

[0051] The moving mechanism attachment portion 37 is an attachment portion that can temporarily fix or hold the moving mechanism 4 for easily moving the frame body 3, and has a configuration adapted to the position and the configuration of the moving mechanism 4. In the present embodiment, a concave portion 371 that fits with a part of the moving mechanism 4 is provided on the side where the hoist 35 is provided, and an insertion portion 372 is provided on the opposite side thereof.

[0052] As shown in FIGS. 2(b) and 2(c), the concave portion 371 is a portion that fits with a part of the moving mechanism 4, particularly a component including a fixing portion such as a bearing 43 (described later). For example, the portion corresponding to the bearing 43 has a semi-cylindrical upper side and a rectangular parallelepiped space on the lower side so that the frame body 3 can be easily fitted onto the moving mechanism 4. In addition, the concave portion 371 also includes a portion where the frame body 3 is cut out so as to avoid rotating components of the moving mechanism 4.

[0053] The insertion portion 372 is a hole that penetrates the frame body 3 in the vertical direction (the same as the height direction in the drawing), and a columnar member extending in the vertical direction of the moving mechanism 4 is inserted therethrough. As shown in FIGS. 1(a) and 1(b), the insertion portion 372 is preferably provided over the entire height direction of the vertical frame 31. With such a configuration, the inserted member can be stably held.

[0054] The moving mechanism 4 is a mechanism for easily moving the frame body 3, and is provided with a rotating shaft 41 and a rolling element 42 fixed to the rotating shaft 41. Further, depending on the required functions, one or more of a bearing 43, a retaining plate 44, a journal box 45, and a rudder portion 46 are provided. However, the bearing 43 used in this specification is regardless of the presence or absence of a housing (including those with the bearing 43 exposed), and the journal box 45 refers to an assembly of a bearing portion including a housing and other components.

[0055] The simple installation type lightning strike suppression device X according to the present embodiment includes two types of moving mechanisms 4, namely a first moving mechanism P and a second moving mechanism Q, as shown in FIGS. 2(a), 2(b), and 2(c). The first moving mechanism P has a rotating shaft 41, a pair of rolling elements 42, a pair of bearings 43, and a pair of retaining plates 44. On the other hand, the second moving mechanism Q has a rotating shaft 41, a pair of rolling elements 42, a journal box 45, and a rudder portion 46.

[0056] The rotating shaft 41 is provided in common to the first moving mechanism P and the second moving mechanism Q, and is a cylindrical member that connects the rotating components, to which the rolling element 42, the bearing 43, the retaining plate 44, and the journal box 45 are connected.

[0057] The rolling element 42 is provided in common to the first moving mechanism P and the second moving mechanism Q, is connected concentrically with the rotating shaft 41, and is a disk-shaped or cylindrical member that contacts the ground G and rotates to easily move the frame body 3. Examples include tires, trailers, wheels, etc.

[0058] The first moving mechanism P has a rotating shaft 41 that is longer than the short side of the frame body 3 in the horizontal direction, and the distance between the pair of rolling elements 42 is longer than the short side of the frame body 3. Further, a configuration in which the diameter of the rolling element 42 is about twice the length in the height direction of the standing frame 31 is preferable. With such a configuration, as shown in FIG. 2(b), the first moving mechanism P can stably support the frame body 3 while ensuring the height from the ground G to the lower surface of the frame body 3.

[0059] The bearing 43 is a general bearing that combines a fixed-side annular member and a rotating-side annular member via rolling elements. It is provided concentric with the rotating shaft 41 and with a predetermined gap inside the rolling elements 42, and two such bearings are provided. In the present embodiment, in order to support all the loads of the lightning strike suppression device main body 1, the support 2, and the frame body 3 with a small number of parts, FIGS. 2(b) and 2(c) show the form of a radial roller bearing. However, it may be appropriately changed according to the environment in which the simple installation type lightning strike suppression device X such as a ball bearing or a thrust bearing is moved.

[0060] The pressing plate 44 is a flat plate-shaped member that is fixed adjacent to the bearing 43 and concentric with the rotating shaft 41, and prevents the bearing 43 from shifting in the axial direction of the rotating shaft 41.

[0061] When the first moving mechanism P is attached to the moving mechanism attachment portion 37, the bearing 43 and the pressing plate 44 are fitted into the recess 371. At this time, a stopper or the like for holding the bearing 43 so that it does not come off may be provided on the recess 371 side. With such a configuration, the frame body 3 and the first moving mechanism P can be easily attached and detached.

[0062] As shown in FIG. 2(b), the second moving mechanism Q has a rotating shaft 41 that is shorter than the short side of the frame body 3 in the horizontal direction, and the diameters of the pair of rolling elements 42 are smaller than the height from the ground G to the lower surface of the frame body 3 when the first moving mechanism P is attached to the frame body 3. With such a configuration, the second moving mechanism Q can be housed and attached under the frame body 3.

[0063] The axle box 45 is a box-shaped or cylindrical assembly provided at the center of the second moving mechanism Q, particularly in the middle of the pair of rolling elements 42, and includes a bearing concentric with the rotating shaft 41, a housing that covers this bearing, and a hole portion for attaching the rudder portion 46.

[0064] The rudder part 46 is a member that is connected to the axle box 45 and enables the second moving mechanism Q to rotate about an axis in the vertical direction (the same as the height direction), and includes a transmission part 461 and a control lever 462. With such a configuration, when the frame body 3 moves, the traveling direction can be easily changed manually.

[0065] The transmission part 461 is a columnar member that penetrates the insertion part 372 and whose lower end penetrates into the hole part of the axle box 45, and is fixed to the control lever 462 at the upper end. Further, the lower end of the transmission part 461 and the hole part of the axle box 45 may have any cross-sectional shape other than circular, that is, elliptical, fan-shaped, polygonal, wedge-shaped, etc. if there is a locking part. Furthermore, the transmission part 461 has a cross-section with a slightly smaller radius with respect to the insertion part 372, whereby it can rotate easily with respect to the frame body 3.

[0066] The control lever 462 is a rod-shaped member that is fixed to the upper end of the transmission part 461 and extends in the horizontal direction and away from the frame body 3. By the user gripping the control lever 462 by hand and rotating it around the transmission part 461, the second moving mechanism Q can be easily rotated with a small force, and the traveling direction of the frame body 3 can be changed.

[0067] When the second moving mechanism Q is removed from the frame body 3, as shown in Fig. 3(a), the rudder part 46 is detached from the axle box 45, and when it is attached to the frame body 3, as shown in Figs. 2(a) and 2(b), it is provided by penetrating the insertion part 372 and connecting to the axle box 45. With such a configuration, the second moving mechanism Q can be easily attached to and detached from the frame body 3.

[0068] The simple installation type lightning strike suppression device X according to the present embodiment may have the following configuration. However, the configuration shown below is merely an example, and its presence or absence can be arbitrarily determined unless otherwise specified.

[0069] ≪Modification example≫ The frame body 3 is provided with a grip that can be held by a user's hand. This grip is made of an insulating material (such as rubber, urethane, etc.) having flexibility to follow the shape of a human hand, and is preferably configured to be wound around, particularly, the upper edge of the vertical frame 31 and the vicinity of the upper end of the protruding portion 36. With such a configuration, when the user applies a force to the frame body 3 to move it, no extra force is required, and the simple installation type lightning strike suppression device X can be easily moved to a desired location.

[0070] The bottom plate 32 is provided with one or more holes at one location in the accommodation portion 311 formed together with the vertical frame 31. With such a configuration, even if water enters the accommodation portion 311 due to rain or the like, it can be easily discharged.

[0071] The frame body 3 may have a conductive cable that can be stored and pulled out. This conductive cable is a conductor and a linear member that is electrically connected to the conductive material portion of the frame body 3, is pulled out from the frame body 3 placed on the ground G of the installation location, and assists the grounding state by the vertical frame 31 and the bottom plate 32. In particular, when the installation location of the frame body 3 is a place paved with concrete (such as an apron), since a metal member (such as a reinforcing bar) is embedded in the ground, by connecting the conductive cable to the metal member, the lightning strike suppression device main body 1 can be grounded more stably.

[0072] In the moving mechanism 4, all the rolling elements 42 provided in the first moving mechanism P and the second moving mechanism Q may have the same diameter. With such a configuration, the types of components constituting the moving mechanism 4 can be reduced. Even in this case, as in FIG. 2(a), in the first moving mechanism P, the bearing 43 is fitted and attached to the concave portion 371, and in the second moving mechanism Q, it is attached so as to fit between the bottom plate 32 and the ground G. Therefore, when the frame body 3 is moved, the entire frame body 3 tilts so that the side of the second moving mechanism Q is higher with respect to the ground G.

[0073] Hereinafter, with reference to the drawings, the implementation method of the present embodiment will be described in detail. Also, the implementation method shown below is an example, and the implementation method is not limited to this, and the order may be reversed.

[0074] ≪Implementation Method≫ When the user does not use the simple installation type lightning strike suppression device X, as shown in Fig. 3(a), the moving mechanism 4 is removed from the frame body 3, and as shown in Fig. 5, the lightning strike suppression device main body 1 and the divided support body 2 are stored in the storage portion 311 for storage (storage step). In particular, when there are a plurality of simple installation type lightning strike suppression devices X, as shown in Fig. 3(c), the frame bodies 3 in which each component is stored are stacked in the height direction for storage. Thereby, even at a site where a plurality of simple installation type lightning strike suppression devices X are required, the space for storage during non-use is minimized, and the space can be effectively utilized.

[0075] When the user uses the simple installation type lightning strike suppression device X, from the state shown in Fig. 3(c), the frame body 3 is taken out from above by a forklift, a hand lift, or manual work of a plurality of people, and placed on the ground G together with the moving mechanism 4. Then, the moving mechanism 4 is attached to the frame body 3 in the reverse procedure of the state shown in Fig. 3(a).

[0076] When the user attaches the moving mechanism 4 to the frame body 3, first, the jack is used to lift the side of the hoisting machine 35 of the frame body 3, and the portion between the rolling elements 42 of the first moving mechanism P is inserted thereinto, and the concave portion 371 is placed on the bearing 43 and the pressing plate 44 and fitted. After removing the jack, the user uses the jack again to lift the side of the frame body 3 opposite to the first moving mechanism P and attaches the second moving mechanism Q (moving mechanism attachment step). Here, first, the insertion portion 372 is penetrated through the transmission portion 461, and the lower end portion of the transmission portion 461 that has come out of the lower side of the frame body 3 is penetrated into the axle box 45 and connected. Then the user removes the jack and moves the frame body 3 to a desired location (transportation step).

[0077] When the frame body 3 is moved, the user applies force to the standing frame 31 or the protruding portion 36 manually and operates the rudder portion 46 to change the traveling direction as appropriate. After moving the frame body 3 to a desired location, the user removes the moving mechanism 4 from the frame body 3 in the reverse procedure of the above (detachment step) and places the frame body 3 on the ground G for pressure contact (grounding step).

[0078] Subsequently, the user takes out the support 2 housed in the housing portion 311 and the lightning strike suppression device main body 1. After that, as shown in Fig. 6(a), the user connects the main support columns 21 in series (coaxially), inserts one end thereof into the insertion portion 331 that is laid down horizontally, fixes it, attaches the lightning strike suppression device main body 1 to the other end, and also assembles the suspension support column 23 and the pulley 231, and inserts and fixes them to the suspension support column attachment portion 34. Further, the user extends the wire W from the winch 35, hangs it on the pulley 231, and connects the tip of the wire W to the main support column 21, particularly the connection flange 211.

[0079] After that, the user operates the winch 35 to raise the main support column 21 as shown in Fig. 6(b). Then, as shown in Fig. 7(a), when the main support column 21 stands upright in the height direction, the user stops the winch 35, connects the auxiliary support column 22 to the main support column 21 (connection flange 211) and the frame body 3, and removes the wire W and the suspension support column 23 to make it in the state shown in Fig. 7(b) (supporting step).

[0080] When the user removes the simple installation type lightning strike suppression device X, the user disassembles and houses the lightning strike suppression device main body 1 and the support 2 in the reverse procedure of the above, and moves the frame body 3 to the storage location.

[0081] Hereinafter, with reference to the drawings, the simple installation type lightning strike suppression device X according to the second embodiment of the present invention will be described. For the same configurations as those in the first embodiment, the description will be omitted by using the same reference numerals.

[0082] ≪Second Embodiment≫ In the present embodiment, as shown in Figs. 8(a), 8(c), 9(a), and 9(c), the bottom plate 32 is provided with a bottom portion 321. The bottom portion 321 is a plate-like member having a further thickness downward from the bottom plate 32 and is made of a conductive material. With such a configuration, regardless of the configuration of the moving mechanism attachment portion 37 described later, the frame body 3 can be surely brought into contact with the ground G.

[0083] The first moving mechanism P has a rotating shaft 41, a rolling element 42 and a journal box 45 fixed to the rotating shaft 41. The second moving mechanism Q, similar to the first moving mechanism P, has a rotating shaft 41, a rolling element 42 and a journal box 45 fixed to the rotating shaft 41, and further has a rudder portion 46. In the present embodiment, it is preferable that the first moving mechanism P and the second moving mechanism Q have the same length of the rotating shaft 41 and the same diameter of the rolling element 42, and two rolling elements 42 are provided with the journal box 45 interposed therebetween. Further, the first moving mechanism P is provided at two locations near the corner close to the hoist 35 of the frame body 3, and the second moving mechanism Q is provided at two locations near the corner close to the insertion portion 372 of the frame body 3.

[0084] The moving mechanism mounting portion 37 is provided with a shaft joint portion 373 for the moving mechanism. As shown in FIGS. 8(b) and 9(b), the shaft joint portion 373 for the moving mechanism is provided along the side of the bottom plate 32, and enables the portion excluding the rudder portion 46 of the first moving mechanism P or the second moving mechanism Q to rotate about a horizontal axis. However, it is preferable to provide a stopper such as a screw or a locking tool so that the shaft joint portion 373 for the moving mechanism does not rotate unintentionally during the movement of the frame body 3.

[0085] Here, in the form shown in FIGS. 8(a), 8(b), and 8(c), the shaft joint portion 373 for the moving mechanism is provided outside the mounting position during the movement of the first moving mechanism P and the second moving mechanism Q. In other words, the first moving mechanism P and the second moving mechanism Q rotate outward from the position during movement toward the outside of the frame body 3, and the bottom portion 321 contacts the ground G.

[0086] On the other hand, in the form shown in FIGS. 9(a), 9(b), and 9(c), the shaft joint portion 373 for the moving mechanism is provided inside the mounting position during the movement of the first moving mechanism P and the second moving mechanism Q. In other words, the first moving mechanism P and the second moving mechanism Q rotate inward from the position during movement toward the inside of the frame body 3 and are stored inside the frame body 3, and the bottom portion 321 contacts the ground G.

[0087] Either of the above two configurations can be adopted. With such a configuration, it is not necessary to completely remove the moving mechanism 4 from the frame body 3, and the frame body 3 can be lowered to the ground G and grounded with a simpler operation.

[0088] Hereinafter, with reference to the drawings, the implementation method of the present embodiment will be described in detail. Also, the implementation methods shown below are examples, and the implementation methods are not limited thereto, and the order may be reversed. For the methods similar to the first embodiment, the description will be omitted using the same reference numerals.

[0089] ≪Implementation Method≫ In the simple installation type lightning strike suppression device X according to the present embodiment, when not in use and during installation, as shown in FIG. 8(c) or FIG. 9(c), the moving mechanism 4 is in a state where the rolling element 42 faces upward and the bottom part 321 is in contact with the ground G. When moving the frame body 3 to a desired location from this state, the user rotates the first moving mechanism P and the second moving mechanism Q about the moving mechanism shaft joint portion 373, and switches to a state where only the rolling element 42 is in contact with the ground G, as shown in FIG. 8(a) or FIG. 9(a). When the movement of the frame body 3 is completed and it shifts to a state of not being used or installing the lightning strike suppression device main body 1, the user rotates the first moving mechanism P and the second moving mechanism Q about the moving mechanism shaft joint portion 373 in the reverse direction as described above, and as shown in FIG. 8(c) or FIG. 9(c), the moving mechanism 4 is switched to a state where the rolling element 42 faces the information and the bottom part 321 is in contact with the ground G (rotation step).

[0090] Hereinafter, with reference to the drawings, the simple installation type lightning strike suppression device X according to the third embodiment of the present invention will be described. For the configurations similar to those of the first and second embodiments, the description will be omitted using the same reference numerals.

[0091] ≪Third Embodiment≫ As shown in FIGS. 10(a) and 10(b), in the present embodiment, the protruding portion 36 is configured in a cylindrical shape and incorporates a telescopic portion 361 that can be further telescoped. The telescopic portion 361 is a columnar member that can be telescoped in the direction from the frame body 3 toward the ground G, and is provided stored inside the cylinder of the protruding portion 36 when not in use. Also, the telescopic length of the telescopic portion 361 is longer than the distance from the bottom plate 32 of the frame body 3 to the ground G when the moving mechanism 4 is attached. With such a configuration, when the simple installation type lightning strike suppression device X is in use, the protruding portion 36 can be extended and brought into contact with the ground G, and the first electrode body 11 of the lightning strike suppression device main body 1 can be easily grounded. Furthermore, it becomes unnecessary to attach and detach the moving mechanism 4, and the simple installation type lightning strike suppression device X can be installed more efficiently.

[0092] Hereinafter, the method of implementation of the present embodiment will be described in detail with reference to the drawings. Also, the method of implementation shown below is an example, and the method of implementation is not limited to this, and the order may be reversed. Regarding the same methods as in the first and second embodiments, the description will be omitted using the same reference numerals.

[0093] ≪Method of Implementation≫ When installing the simple installation type lightning strike suppression device X according to the present embodiment at a desired location, the user extends the telescopic portion 361 downward from the state of the frame body 3 shown in FIG. 10(a) as shown in FIG. 10(b), and brings its tip into contact with the ground G (extension step). At this time, it is sufficient that both the moving mechanism 4 and the telescopic portion 361 are in contact with the ground G. However, as shown in FIG. 10(b), the moving mechanism 4 may be lifted off the ground G and only the telescopic portion 361 may be in contact with the ground G. In this case, the user lifts the frame body 3 using a jack. As a result, all the weight of the simple installation type lightning strike suppression device X is concentrated on the telescopic portion 361, so that the telescopic portion 361 is more stably pressed against the ground G.

[0094] Hereinafter, the simple installation type lightning strike suppression device X according to the fourth embodiment of the present invention will be described with reference to the drawings. Regarding the same configurations as in the first, second, and third embodiments, the description will be omitted using the same reference numerals.

[0095] <<Fourth Embodiment>> As shown in FIGS. 11(a) and 11(b), in this embodiment, the frame body 3 has a deployed grounding portion 38. The deployed grounding portion 38 is a member made of a conductive material including a movable beam housing portion 381, a movable beam 382, and an adjuster 383, and expands the contact area of the frame body 3 with respect to the ground G.

[0096] The movable beam housing portion 381 is a pair of flat plate-like members provided along the outer periphery of the standing frame 31, and sandwiches the movable beam 382 in the height direction. In FIGS. 11(a) and 11(b), the movable beam housing portion 381 is configured like fins protruding from the side surface of the standing frame 31. However, when the standing frame 31 is made of H-shaped steel, the internal space of the U-shaped cross-section formed by the web and the flange can be treated as the movable beam housing portion 381. Further, the movable beam housing portion 381 has a joint portion to which the movable beam 382 can be attached.

[0097] The movable beam 382 is pivotally attached to the movable beam housing portion 381 and is a columnar member that can be deployed further outward and horizontally from the outer periphery of the standing frame 31. In FIGS. 11(a) and 11(b), the movable beam 382 rotates on a horizontal plane around a joint portion (rotation axis) provided in the movable beam housing portion 381, and expands the short side direction of the frame body 3. With such a configuration, the occupied area by the frame body 3 can be suppressed during movement or non-use, and the stability of the entire simple installation type lightning strike suppression device X can be improved when the lightning strike suppression device main body 1 and the support 2 are erected.

[0098] The adjuster 383 is a box-shaped or plate-shaped member disposed below the tip portion of the deployed movable beam 382, and electrically connects the movable beam 382 and the ground G. In FIGS. 11(a) and 11(b), the height of the adjuster 383 is configured to be substantially equal to the distance from the lower surface of the movable beam 382 to the ground G in the state where the moving mechanism 4 is attached, but may be adjusted to the distance from the lower surface of the movable beam 382 to the ground G in the state where the moving mechanism 4 is removed. In other words, regardless of the presence or absence of the moving mechanism 4, it is preferable that the frame 3 is grounded simultaneously by both the bottom plate 32 and the adjuster 383. With such a configuration, the frame 3 can be easily and stably grounded.

[0099] The simple installation type lightning strike suppression device X according to the present embodiment may have the following configuration. However, the following configuration is merely an example, and its presence or absence can be arbitrarily determined unless otherwise specified.

[0100] ≪Modification example≫ As a modification example of the deployed grounding portion 38 shown above, a configuration in which the movable beam 382 is slidably attached to the movable beam storage portion 381 can be mentioned. In this case, the movable beam storage portion 381 is a cylindrical member provided parallel to the axial direction of the rotation shaft 41 of the first moving mechanism P, and is configured to store the movable beam 382 therein. In other words, the configurations of the protruding portion 36 and the telescopic portion 361 shown in the third embodiment are provided in the horizontal direction. Thereby, the movable beam 382 is stored during movement or when not in use, and in the state where the lightning strike suppression device main body 1 and the support 2 are erected, the tip of the movable beam 382 is placed on the adjuster 383 as described above, and the frame 3 is installed.

[0101] Hereinafter, with reference to the drawings, the implementation method of the present embodiment will be described in detail. Also, the implementation method shown below is an example, and the implementation method is not limited to this, and the order may be reversed. Note that, for the same methods as in the first, second, and third embodiments, the description will be omitted using the same reference numerals.

[0102] ≪Implementation method≫ When installing the simple installation type lightning strike suppression device X according to this embodiment at a desired location, as shown in Fig. 11(b), the user expands the movable beam 382 in the horizontal direction, and further inserts the adjuster 383 under the movable beam 382 to electrically connect the movable beam 382 to the ground G. Fig. 11(b) shows a state where the deployment grounding part 38 is handled without removing the moving mechanism 4, but the user may remove the moving mechanism 4 from the frame body 3 (detachment process) and ground the movable beam 382 with a thinner adjuster 383. Thereby, the horizontal installation area of the frame body 3 can be expanded, and the lightning strike suppression device main body 1 and the support body 2 can be supported more stably. In addition, since the frame body 3 contacts the ground G with the combined area of the bottom plate 32 and the bottom surface of the adjuster 383, the first electrode body 11 can be grounded more stably.

[0103] Hereinafter, with reference to the drawings, the simple installation type lightning strike suppression device X according to the fifth embodiment of the present invention will be described. Regarding the same configurations as those in the first, second, third, and fourth embodiments, the description will be omitted using the same reference numerals.

[0104] ≪Fifth Embodiment≫ Figs. 12(a) and 12(b) are respectively a right side view and a front view showing the frame body 3 capable of transporting the simple installation type lightning strike suppression device X according to this embodiment, the moving mechanism 4 attached to the frame body 3, and the power device 5, and Fig. 12(c) is an enlarged view showing the moving mechanism 4 in Fig. 12(b) and the configurations of each part related thereto.

[0105] As shown in Figs. 12(a) and 12(b), the frame body 3, particularly the moving mechanism attachment part 37, is provided with an intermediate link 374 connected to the second moving mechanism Q. In addition, the second moving mechanism Q includes a brake 47 in addition to the rotation shaft 41, the rolling element 42, the axle box 45, and the rudder part 46, and further a power device 5 is provided.

[0106] As shown in Fig. 12(a), in order to secure a space for the second moving mechanism Q to provide the power device 5, the height from the bottom plate 32 to the ground G may be higher than that of the simple installation type lightning strike suppression device X according to other embodiments. In this case, the frame body 3 according to the present embodiment is provided with a bottom part 321, and a space for the second moving mechanism Q to enter is secured in a notch-like manner.

[0107] The intermediate link 374 is a member that connects the second moving mechanism Q to the vertical frame 31, and includes a flat plate-like member or a columnar member that is rotatably connected by a shaft joint. With such a configuration, even when the vertical frame 31 has a thickness in the height direction, the second moving mechanism Q can be bounced up to the upper side of the vertical frame 31, and the frame body 3 can be easily grounded. Further, it is preferable that the vertical frame 31 in the present embodiment is provided with a notch for accommodating the intermediate link 374. With such a configuration, a space for the second moving mechanism Q can be secured by the size (width, thickness, etc.) of the intermediate link 374.

[0108] The frame body 3 has a moving mechanism pulley 39 along the side near the second moving mechanism Q. The moving mechanism pulley 39 is a general pulley used by hanging a wire W. In the present embodiment, when pulling up the second moving mechanism Q to the upper side of the vertical frame 31, the wire W extending from the winch 35 is hooked and used. At this time, as shown in Figs. 12(b) and 12(c), the moving mechanism pulley 39 is provided at a position deviated from the center of the frame body 3. Thereby, the wire W from the winch 35 does not interfere with the main support column mounting portion 33, the suspension support column mounting portion 34, and the rudder portion 46.

[0109] The brake 47 is a braking device provided in the second moving mechanism Q, and stops the rotation of the rotating shaft 41 by a handle operation. With such a configuration, the moving frame body 3 can be easily braked and basically or stopped.

[0110] The power device 5 includes an electric motor 51, a motor support 52 that supports the electric motor 51, a battery 53 that can supply power to the electric motor 51, and an electric cable 54 that connects the electric motor 51 and the battery 53 to form a circuit.

[0111] The electric motor 51 is a general electric motor that converts electrical input into rotational motion output, and the output shaft is connected to the rotating shaft 41. Thereby, the rotating shaft 41 is rotated by the electric motor 51. A speed reducer is provided between the output shaft of the electric motor 51 and the rotating shaft 41 (or the rolling element 42), and the rotational motion generated by the electric motor 51 is appropriately decelerated and transmitted to the rolling element 42. With such a configuration, the frame 3 can be moved by self-propulsion. The speed reducer includes a planetary gear mechanism or the like.

[0112] The electric motor 51 may be provided integrally with the rolling element 42. In this configuration, by adopting a wheel motor, the size of the entire second moving mechanism Q can be suppressed, and in addition, the bias of the weight of the entire simple installation type lightning strike suppression device X can be suppressed.

[0113] The motor support 52 is a member including a beam provided between the rolling element 42 and the bottom plate 32 in the height direction, and a column or plate that suspends the electric motor 51 from the beam. The motor support 52 is connected to the rotating shaft 41 via the electric motor 51, and in the beam, it is connected to a column that connects the axle box 45 and the rudder part 46, and rotates horizontally together with the rotating shaft 41 etc. by the operation of the rudder part 46.

[0114] The battery 53 is a battery (which may be a primary battery or a secondary battery) that generates a voltage for the operation of the electric motor 51. Since the present invention is assumed to be used outdoors, as shown in FIGS. 12(a) to 12(c), a configuration in which it is housed in a housing and a circuit is formed with the electric motor 51 by the electric cable 54 is preferable. In addition, the housing that houses the battery 53 preferably has a configuration in which a switch or a reception port for electromagnetic waves or the like is provided on the surface. With such a configuration, the user can easily operate the power supply by the battery 53 by switch operation or remote control operation.

[0115] The electric cable 54 is a linear member that connects the electric motor 51 and the battery 53 to form a circuit, and is a general wiring whose surface is coated with an insulating material. In the present embodiment, as shown in FIGS. 12(a) to 12(c), it is preferably provided in a slightly loose state rather than a tense state. With such a configuration, it is possible to respond to the rotation of the electric motor 51 due to the operation of the rudder unit 46, and it is possible to avoid the risk of disconnection due to pressure contact with the frame body 3.

[0116] The power device 5 preferably has a configuration in which the surfaces of its respective parts are coated with an insulating material. With such a configuration, the entire power device 5 is electrically isolated from each conductor component related to the grounding of the lightning strike suppression device main body 1, preventing malfunctions.

[0117] FIGS. 13(a) to 13(c) are right side views showing the state when grounding the frame body 3, and FIG. 13(d) is an enlarged view showing the state of the second moving mechanism Q and the moving mechanism pulley 39 in the region F of FIG. 13(c). As shown in each figure, the second moving mechanism Q rotates according to the movable range of the intermediate link 374, jumps up above the standing frame 31, and the frame body 3 becomes in a state where it can contact the ground G. At this time, the wire W is connected to any one of the parts (for example, the axle box 45, the electric motor 51, the motor support 52) that can rotate below the intermediate link 374 of the second moving mechanism Q, is hung on the moving mechanism pulley 39, and is wound up by the hoisting machine 35, so that the entire second moving mechanism Q is pulled up above the standing frame 31. The pulled-up second moving mechanism Q is placed or stored on the upper surface of the frame body 3 as shown in FIG. 13(d).

[0118] Hereinafter, the implementation method of the present embodiment will be described in detail with reference to the drawings. Also, the implementation method shown below is an example, and the implementation method is not limited to this, and the order may be reversed. For the methods similar to the first, second, third, and fourth embodiments, the description will be omitted using the same reference numerals.

[0119] ≪Implementation Method≫ Fig. 13(a) shows the state of the frame body 3 and the second moving mechanism Q with the first moving mechanism P removed. When the user removes the first moving mechanism P from the frame body 3, the user lifts and supports the frame body 3 using the jack 6. At this time, the user lifts the frame body 3 with a plurality of jacks 6 so that the second moving mechanism Q is separated from the ground G. Further, the user pulls out and removes the rudder part 46 from the axle box 45.

[0120] Subsequently, the user pulls out the wire W from the hoist 35, hooks the wire W on the pulley 39 for the moving mechanism, and attaches the tip of the wire W to an appropriate position (a part rotatable below the intermediate link 374) of the second moving mechanism Q. Then, as shown in Fig. 13(b), when the wire W is wound up by the hoist 35, the second moving mechanism Q is pulled up so as to jump onto the upper side of the vertical frame 31 according to the movable range of the intermediate link 374.

[0121] As shown in Fig. 13(c), after the entire second moving mechanism Q is pulled up to the upper side of the vertical frame 31, the rolling element 42 is placed on the upper surface of the vertical frame 31 or in the accommodating part 311. At this time, the user supports the second moving mechanism Q by sandwiching a buffer material between the second moving mechanism Q and the frame body 3. Thereby, the second moving mechanism Q, particularly the rolling element 42, can be handled without applying an impact. Examples of this buffer material include a column body provided with an impact absorbing material (shock absorber).

[0122] Finally, the user removes the wire W from the second moving mechanism Q, checks that there is no interference such as the electric cable 54 being entangled with other parts, and contracts the jack 6 to place the frame body 3 on the ground G.

[0123] The user lowers the second moving mechanism Q to the ground G side in the reverse procedure of the above, and switches the frame body 3 to a movable state.

[0124] Hereinafter, the simple installation type lightning strike suppression device X according to the sixth embodiment of the present invention will be described with reference to the drawings. For the same configurations as those in the first, second, third, fourth, and fifth embodiments, the description will be omitted using the same reference numerals.

[0125] <<Sixth Embodiment>> The simple installation type lightning strike suppression device X according to this embodiment includes a lightning strike suppression device main body 1, a support 2, and a frame body 3, as shown in FIGS. 14(a), 14(b), 15(a), and 15(b). The difference from the previous embodiment is that it does not include a moving mechanism 4 and a power device 5. With such a configuration, the number of parts of the simple installation type lightning strike suppression device X can be reduced, and it can be transported and installed at a desired location.

[0126] FIGS. 15(a) and 15(b) show a state in which the lightning strike suppression device main body 1 is erected on the frame body 3 by the support 2 in this embodiment. At this time, the bottom surface of the frame body 3 of the lightning strike suppression device main body 1 contacts the ground G as a grounding portion, so that the first electrode body 11 and the ground G are electrically connected. In this case, if the weight of the frame body 3 is large, it can be more stably pressed against the ground G, and the grounding state can be kept good. Also, thereby, even when wind hits the lightning strike suppression device main body 1 and the support 2 in the horizontal direction, the entire simple installation type lightning strike suppression device X can withstand strong winds without the lightning strike suppression device main body 1 falling easily.

[0127] The frame body 3 preferably has an adjustment member capable of expanding the contact area between the grounding portion and the ground G. As shown in FIG. 15(b), the ground G where the simple installation type lightning strike suppression device X is installed is not always flat and may include unevenness. For example, there are slight unevenness on the concrete paving surface at an airport or the like. At this time, the contact area between the frame body 3 and the ground G becomes smaller than the area of the bottom surface of the frame body 3 or the area of the bottom plate 32, and the area for grounding the lightning strike suppression device main body 1 becomes smaller. In addition to compensating for this, the adjustment member may be configured to be able to further expand the contact area with the ground G determined by the vertical frame 31 to the outside. Also, the adjustment member may be in any form as long as its length can be adjusted in the height direction shown in each figure. Hereinafter, preferred examples of the configuration of the adjustment member will be given.

[0128] As shown in Fig. 16(a), the frame body 3 is provided with a telescopic portion 361 that can expand and contract in the height direction, particularly in the direction of the ground G, as a form of adjustment member. Similar to the telescopic portion 361 shown in the third embodiment, the telescopic portion 361 has a columnar member that can be stored in the cylindrical protrusion 36 and a flat plate-shaped member provided at the end on the ground G side. With such a configuration, the telescopic portion 361 extends toward the gap between the frame body 3 and the ground G, and the contact area can be easily expanded at the portion where the standing frame 31 or the bottom plate 32 does not contact the ground G.

[0129] As shown in Fig. 16(b), the frame body 3 is provided with an adjuster 383 that can be inserted into the gap between the lower surface of the frame body 3 (the lower surface of the standing frame 31 or the bottom plate 32) and the ground G, as another form of adjustment member. At this time, the adjuster 383 is a thin plate-shaped member that can be inserted into the gap between the lower surface of the frame body 3 and the ground G, different from the fourth embodiment. Also, there may be a plurality of types of adjusters 383 with different thicknesses, sizes, or shapes in the surface direction. Thereby, a plurality of types of adjusters 383 can be appropriately combined and used according to the unevenness of the ground G, and the contact area between the frame body 3 and the ground G can be easily expanded. Further, the adjuster 383 in this form may have a shape that is corrugated and folded in the thickness direction based on a flat plate shape. Thereby, the adjuster 383 can be pressed against both the frame body 3 and the ground G based on the principle of a leaf spring, and a more stable grounding state can be achieved.

[0130] As shown in FIG. 16(c), as yet another form of the adjustment member, the frame body 3 has a deployed grounding portion 38. Similar to the fourth embodiment, the deployed grounding portion 38 is provided with a movable beam housing portion 381, a movable beam 382, and an adjuster 383. In this form, the movable beam housing portion 381 is configured to utilize the internal space of the U-shaped cross-section formed by the web and flange of the H-beam forming the vertical frame 31. Further, the movable beam 382 is connected to the movable beam housing portion 381 by a pivot joint extending in the height direction, and is a columnar member that can rotate horizontally from the movable beam housing portion 381. Furthermore, the adjuster 383 is a flat plate-shaped member that can be inserted into the gap between the tip of the movable beam 382 and the ground G, and can expand the contact area between the frame body 3 and the ground G outward. With such a configuration, the grounding of the lightning strike suppression device main body 1 can be made more stable, and in addition, the short side direction in the horizontal direction of the frame body 3 can be easily expanded, improving the stability when the simple installation type lightning strike suppression device X is installed.

[0131] Hereinafter, the method for implementing the present invention will be described in detail with reference to the drawings. Also, the implementation method shown below is an example, and the implementation method is not limited to this, and the order may be reversed.

[0132] ≪Implementation Method≫ When transporting the simple installation type lightning strike suppression device X according to the present embodiment to the installation location, the user manually or places the frame body 3 in which the lightning strike suppression device main body 1 and the support body 2 are accommodated in the accommodation portion 311 on the loading platform of a transport vehicle (such as a truck) and transports it to the desired location. Thereby, it is possible to easily transport the simple installation type lightning strike suppression device X without the need for special devices or the like, and it is also not necessary to attach and detach parts for transportation, reducing the man-hours related to the transportation of the simple installation type lightning strike suppression device X.

[0133] Subsequently, the user places the transported frame body 3 on a desired ground G and, if necessary, uses an adjustment member to expand the contact area between the frame body 3 and the ground G (ground contact area expansion step). Thereafter, the user erects the lightning strike suppression device main body 1 and the support body 2 in the same procedure as in other embodiments. When withdrawing the simple installation type lightning strike suppression device X, the operation is performed in the reverse procedure of the above.
