Description

[Technical field]

[0001] The present invention relates to an easily installed lightning suppression device for protecting an object from lightning damage by suppressing lightning strikes, which can be moved to a desired location. [Background technology]

[0002] In the conventional lightning protection concept for protecting infrastructure against lightning strikes, most methods involve receiving lightning strikes with a needle-type lightning rod (Franklin rod) and directing them to the ground, based on the view that lightning strikes cannot be prevented. In response to this, the present inventors have proposed a lightning suppression device shown in Patent Document 1 in order to protect the protected object by minimizing the occurrence of lightning strikes.

[0003] This lightning suppression device has an inner electrode body and an outer electrode body in a spherical shell shape with the same center point sandwiching an insulator, and only the inner electrode body is grounded.

[0004] For example, when a thundercloud with negative charges distributed at the cloud base approaches, the opposite charge (positive charge) is distributed on the surface of the earth, and positive charges also gather on the grounded inner electrode body. Then, the outer electrode body, which is placed through an insulator, becomes negatively charged due to the effect of a capacitor. This action makes it difficult for upward streamers to occur in the lightning arrester and its surroundings, suppressing the occurrence of lightning strikes.

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

[0006] In addition, infrastructure that needs to be protected from lightning strikes is not limited to buildings, but also includes vehicles parked outdoors and electrical appliances such as computers. Because the objects protected by lightning suppression devices are essentially anything that uses electricity, regardless of whether it is movable or immovable, there is a demand for lightning suppression devices that can be easily installed on things other than buildings.

[0007] In response to these issues, the present inventors proposed the lightning suppression device shown in Patent Document 2. This lightning suppression device is equipped with a base that can be attached to the rear of a vehicle and moved as a trailer, and a support pole and the main body of the lightning suppression device can be assembled at the destination, making it possible to take measures against lightning strikes at any location. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Patent No. 6128539 [Patent Document 2] Patent No. 7405348 Summary of the Invention [Problem to be solved by the invention]

[0009] The lightning suppression device described in Patent Document 2 improves flexibility in lightning countermeasures, such as by allowing the device to be installed in parking areas in accordance with the locations where aircraft are parked. However, because this lightning suppression device is large, it requires a car to be towed to move it, and it takes up a lot of space even when not in use.

[0010] In addition to the above, when transporting the lightning suppression device, it is possible to stack the devices on the bed of a truck or hold them manually, and considering that a structure for installation must be provided in addition to the wheels, a base structure that permanently has wheels attached is inefficient in terms of handling, equipment costs, and number of parts.

[0011] In view of the above problems, the present invention aims to provide an easily installed lightning suppression device that is lower cost, requires less space, can be easily moved and set up manually, and can maintain a stable grounding state. [Means for solving the problem]

[0012] The present invention, which solves the above-mentioned problems, is a portable, easily installed lightning suppression device that comprises a lightning suppression device main body, which constitutes the main part of the lightning suppression, a support body that supports the lightning suppression device main body at a predetermined height, and a frame body on which the support body can be erected and which can be transported.The frame body has a frame member that forms the peripheral portion and provides weight, a housing section that can house the lightning suppression device main body and the support body during transport, and a grounding section that grounds the lightning suppression device main body. With such a configuration, the lightning suppression device can be moved and set up easily by hand at lower cost, while taking up less space, and the grounding condition can be kept stable.

[0013] In a preferred embodiment of the present invention, the frame further includes an adjustment member capable of enlarging the contact area between the ground contact portion and the ground. With this configuration, it is possible to easily accommodate unevenness in the ground on which the frame body is grounded, and to make the grounding state of the lightning suppression device more stable.

[0014] In a preferred embodiment of the present invention, the adjustment member includes an expandable portion that is expandable in the height direction. With this configuration, the main body of the lightning suppression device can be grounded with a simple operation.

[0015] In a preferred embodiment of the present invention, the adjustment member includes an adjustment tool that can be inserted into a gap between the lower surface of the frame and the ground. With this configuration, the electrical connection area between the frame body and the ground can be easily ensured with a small number of parts.

[0016] In a preferred embodiment of the present invention, the frame has a protruding portion that protrudes in the height direction. With this configuration, multiple frames can be stacked for storage when not in use, and can also be easily transported.

[0017] In a preferred embodiment of the present invention, the frame has a support attachment portion, and the support attachment portion is provided with a rotatable joint portion. With this configuration, the support body to which the lightning suppression device main body is attached can be easily erected.

[0018] In a preferred embodiment of the present invention, the joint portion is provided rotatably about a horizontal axis. With this configuration, the lightning suppression device body can be easily erected, and the direction in which it should be knocked down when removed is fixed, making it easy to ensure safety.

[0019] In a preferred embodiment of the present invention, the apparatus further comprises a moving mechanism having a rotation shaft, and the frame further comprises an attachment portion to which the moving mechanism can be temporarily fixed. With this configuration, the lightning suppression device can be easily moved and set up manually.

[0020] In a preferred embodiment of the present invention, the mounting portion is provided with a recess that fits with a part of the moving mechanism. With this configuration, the moving mechanism can be easily attached and detached, and the frame can be easily switched between transportation and grounding.

[0021] In a preferred embodiment 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 this configuration, the moving mechanism can be easily rotated, and the frame can be easily switched between being transported and being grounded.

[0022] In a preferred embodiment of the present invention, a plurality of the movement mechanisms are attached to the frame, and at least one of the movement mechanisms has a rudder portion rotatable about an axis in the vertical direction. With this configuration, the direction of travel can be easily changed even manually when the frame is being transported.

[0023] The present invention, which solves the above-mentioned problems, is a method for installing an easily installable lightning suppression device, including the steps of: housing the lightning suppression device main body, which constitutes the main part of the lightning suppression, and a support body that supports the lightning suppression device main body at a predetermined height, in a frame body that allows the support body to be erected and transported; a transporting step of transporting the frame body housing the lightning suppression device main body and the support body to an installation site; a grounding step of grounding the frame body; and a support step of erecting and fixing the support body to which the lightning suppression device main body is attached to the frame body, thereby supporting the lightning suppression device main body at a predetermined height. This method allows the lightning suppression device to be moved and set up easily by hand at lower cost, while minimizing the space it occupies, and further allows the grounding condition to be kept stable.

[0024] In a preferred embodiment of the present invention, the grounding step includes a contact surface enlarging step of enlarging the electrical contact area between the lower surface of the frame and the ground using an adjustment member whose length is adjustable in the height direction. By using this method, the grounding state of the lightning suppression device body can be made more stable.

[0025] In a preferred embodiment of the present invention, the method further includes a moving mechanism mounting step of fixing a moving mechanism having a rotation shaft to the frame that houses the lightning suppression device main body and the support body. In this manner, the easily installable lightning suppression device can be easily transported to the installation site. Effect of the Invention

[0026] The present invention, which solves the above problems, provides an easily installed lightning suppression device that is lower cost, requires less space, can be easily moved and set up manually, and can maintain a stable grounding state. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] Hereinafter, the easily-installed lightning suppression device X according to each embodiment of the present invention will be described with reference to the drawings. The description will be made in detail in the order of the configuration of the embodiment, the method of implementation, and other examples. It should be noted that the following embodiments are merely examples of the present invention, and the present invention is not limited to the following embodiments.

[0031] Here, the form of the easily installed lightning suppression device X shown in the drawings from Fig. 2 onwards conforms to Fig. 1(b) for the sake of explanation, but it is also possible to convert it appropriately to a form conforming to Fig. 1(a). This also applies mutatis mutandis to the explanation of other embodiments.

[0032] The lightning suppression device main body 1 is a device that constitutes the main part of the easily installed lightning suppression device X, and as shown in FIG. 4, has a first electrode body 11 formed in an approximately sphere or approximately spherical shell shape from a conductive material, a second electrode body 12 (which may be divided into two parts, a ground side electrode body 121 and a tip side electrode body 122, or may be molded as a single unit) formed in an approximately concentric spherical shell shape with a predetermined gap between the first electrode body 11, a connecting post 13 made of a conductive material that supports the first electrode body 11 and enables it to be connected 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 suppression device main body 1 is connected to the support 2, particularly the main support column 21 (described later), by the connection column 13. The first electrode body 11, the connection column 13, the support 2, and the frame body 3 are all made of conductive materials and are assembled in an electrically connected configuration, so that the first electrode body 11 is grounded and the lightning suppression device main body 1 acts as a capacitor, suppressing the occurrence of lightning strikes.

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

[0035] The main support columns 21 are made of a conductive material, and as shown in Figures 5, 6(a), 6(b), 7(a), and 7(b), are multiple columnar members that are connected in series in the length direction to obtain a predetermined height required for installing the lightning suppression device main body 1, and are then erected on the frame body 3. In the drawings, a form consisting of three main support columns 21 is shown, but the number of main support columns may be different as long as the predetermined height can be obtained. In addition, although not shown in the drawings, the main support columns 21 are connected to each other by, for example, fixing flanges or stepped portions provided at the ends with bolts.

[0036] Of the multiple main support columns 21, at least one main support column 21 is preferably configured to have a connection flange 211. The connection flange 211 is a flat plate-shaped member that enlarges the cross section of the main support column 21, and is provided with an attachment portion to which the auxiliary support column 22 (described later) and the working wire W can be attached. With such a configuration, parts around the main support column 21 can be easily attached.

[0037] The auxiliary support columns 22 are columnar members that hold the main support column 21 in an upright position, and as shown in Figure 7(b), are connected in multiple diagonal directions from the middle of the main support column 21, particularly from the connection flange 211, toward the frame body 3, forming a cone to support the main support column 21.

[0038] As shown in Figures 6(a), 6(b) and 7(a), suspension pillar 23 is a columnar member erected obliquely from frame 3 at a predetermined elevation angle, and is provided so as to move away from the erected position of main support pillar 21 as it moves upward in the height direction. Suspension pillar 23 also has pulley 231 at its tip. With this configuration, wire W attached to connection flange 211 is hung on pulley 231, and main support pillar 21 can be easily raised by pulling wire W.

[0039] The frame 3 is a frame portion of a transport means that enables the lightning suppression device main body 1 and the support body 2 to be transported to a desired location (installation location), and has a vertical frame 31, a bottom plate 32, a main support pole mounting portion 33, a suspension pole mounting portion 34, a hoist 35, a protruding portion 36, and a transport mechanism mounting portion 37. This makes the lightning suppression device mobile.

[0040] As shown in Fig. 1(a) or 1(b), the vertical frame 31 is a frame member that forms the periphery of the frame body 3 and provides it with weight. This configuration improves the strength of the frame body 3, making it easier and safer to transport to the installation site. In addition, by increasing the weight of the periphery, when the frame body 3 is placed on the ground G, it becomes more compliant with slight unevenness of the ground G, allowing it to make more stable contact with the ground G and maintain a more stable ground contact state as a ground contact portion.

[0041] The vertical frame 31 in this embodiment is a member that adds height to the frame body 3 and determines the overall size and shape. As shown in Fig. 1(a), the vertical frame 31 is made of H-shaped steel materials (other metal materials, such as metal beams or metal plates, L-shaped steel materials, square tubular steel materials, etc., may also be combined) to form a substantially rectangular shape in the horizontal direction. By using H-shaped steel materials, the weight of the frame body 3 increases compared to a combination of metal plates, so that the frame body 3 can be more stably placed on the ground.

[0042] The bottom plate 32 is a flat member that covers a part or all of the bottom surface of the vertical frame 31, and is used as a grounding section that can ground the lightning suppression device main body 1, and the vertical frame 31 and the bottom plate 32 form a receiving box-shaped storage section 311. This allows the lightning suppression device main body 1 and the support body 2 to be stored in the frame 3. With this configuration, all of the components of the easily installed lightning suppression device X can be easily transported to a desired location.

[0043] It is preferable that the vertical frame 31 is not only an outer frame that determines the outer shape of the frame body 3, but also has several additional frames provided to separate the inside. With this configuration, it is possible to reinforce the portions of the frame body 3 where the load is particularly concentrated, such as the main support column mounting portion 33 and the hoisting machine 35.

[0044] 3(b), the main support pole mounting part 33 is a support pole mounting part provided in approximately the center of the frame body 3 in the horizontal direction, and includes an insertion part 331 into which the main support pole 21 is inserted and supported, a movable bottom plate 332 that closes the bottom of the insertion part 331, and an upright installation shaft joint part 333 that allows the insertion part 331 and the movable bottom plate 332 to rotate. With this configuration, the horizontal width of the frame body 3 defined by the upright frame 31 and the bottom plate 32 can be effectively used to support the lightning suppression device main body 1 and the support body 2.

[0045] The insertion part 331 is a cylindrical member into which the main support pole 21 can be inserted and supported in an upright position in the height direction, and is provided with a rib that reinforces the connection with the movable bottom plate 332. The movable bottom plate 332 is a flat plate-like member that closes the bottom of the insertion part 331 and expands further, and is rotatably connected to the vertical frame 31 or the bottom plate 32 via the vertical installation shaft joint part 333. Here, the movable bottom plate 332 can abut on the upper surface of the frame body 3 or the upper surface of the vertical frame 31. With this configuration, when the support body 2 to which the lightning suppression device main body 1 is connected, particularly the main support pole 21, is raised and erected, the movable bottom plate 332 stops the rotation of the vertical installation shaft joint part 333, and the support body 2 is prevented from being raised too far and falling to the other side, so that the installation work of the easily installed lightning suppression device X can be performed safely. Furthermore, when the easily-installable lightning suppression device X is removed, the main support pole 21 falls in only one direction, making it easier to ensure safety during work.

[0046] The erection shaft joint 333 is a shaft joint (hinge joint) that can rotate about an axis in a horizontal position, and allows the insertion part 331 and the movable bottom plate 332 to rotate from the horizontal direction to the height direction. As shown in Figs. 6(a), 6(b) and 7(a), preferably, the insertion part 331 is configured to fall toward the longitudinal side of the frame body 3, in other words, the axis of rotation is parallel to the lateral side of the frame body 3. With this configuration, the fluctuation in load that occurs when erecting or tilting the lightning suppression device main body 1 and the main support pole 21 can be received by the entire longitudinal direction of the frame body 3, making the work safer.

[0047] The vertical frame 31, the bottom plate 32, and the main support pole mounting portion 33 are made of conductive materials. With this configuration, when the support body 2 on which the lightning suppression device main body 1 is mounted is connected, the first electrode body 11 to the bottom plate 32 are electrically connected. Furthermore, at this time, the bottom plate 32 comes into contact with the ground G (concrete, soil, etc.) that can be grounded, so that the first electrode body 11 can be easily grounded. In addition, the conductive part can be pressed against the ground G by the entire horizontal size of the frame body 3 and the weight of the lightning suppression device main body 1, the support body 2, and the frame body 3, and the grounding state of the simply-installed lightning suppression device X can be easily stabilized. Therefore, even under conditions where it is not possible to dig a hole in the ground G to bury a grounding wire (such as an airplane parking area or concrete pavement), the lightning suppression device main body 1 can be reliably grounded.

[0048] Suspension column attachment portion 34 is provided adjacent to main column attachment portion 33, and is composed of a tubular member into which suspension column 23 is inserted and supported, and a flat rib that reinforces the connection portion with upright frame 31 or bottom plate 32. In particular, the direction of the tube is provided so as to support suspension column 23 in an oblique direction and in a direction in which its tip is farthest from main column 21, as shown in Figures 3(b) and 6(a). With this configuration, main column 21 can be easily erected using wire W, as shown in Figures 6(a), 6(b), and 7(a).

[0049] The hoist 35 is a device for winding or drawing out the wire W, and as shown in Figures 1(a) and 1(b), is provided on the upright frame 31 or the bottom plate 32 on the opposite side of the main support column mounting portion 33 with respect to the suspension column mounting portion 34. With this configuration, as shown in Figures 6(a), 6(b), and 7(a), the wire W can be wound up and the main support column 21 can be easily erected, and the main support column 21 can also be knocked down more safely.

[0050] As shown in Figures 1(a), 1(b), 2(a) and 2(b), the protrusion 36 is a columnar member that protrudes in the height direction (upward) in the frame body 3, and the protruding height is higher than any other parts provided on the upper part of the frame body 3, such as the erection shaft joint part 333, the suspension column mounting part 34 and the hoist 35. With this configuration, as shown in Figure 3(c), when the frames 3 are stacked vertically when not in use, the protrusion 36 of the lower frame body 3 receives the bottom plate 32 of the upper frame body 3, so that a gap that allows easy loading and unloading with a forklift can be secured while maintaining stability.

[0051] The moving mechanism mounting portion 37 is a mounting portion capable of temporarily fixing or holding the moving mechanism 4 that easily moves the frame body 3, and has a configuration that matches the position and configuration of the moving mechanism 4. In this embodiment, a recess 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.

[0052] 2(b) and 2(c), recess 371 is a portion that fits with a part of movement mechanism 4, particularly a part including a fixed portion such as bearing 43 (described later), and for example, the portion corresponding to bearing 43 has a semi-cylindrical upper side and a rectangular parallelepiped space below so that frame body 3 can be placed on movement mechanism 4 and easily fitted. In addition, recess 371 also includes a portion where frame body 3 is cut out to avoid rotating parts of movement 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 drawings), and a columnar member extending in the vertical direction of the movement mechanism 4 is inserted through the insertion portion 372. As shown in Figures 1(a) and 1(b), the insertion portion 372 is preferably configured to be 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 3, and is provided with a rotating shaft 41 and a rolling element 42 fixed to the rotating shaft 41, and further includes one or more of a bearing 43, a retaining plate 44, an axle box 45, and a rudder section 46 depending on the required functions. However, the bearing 43 used in this specification may or may not have a housing (including a bearing 43 that is exposed), and the axle box 45 refers to the assembly of the bearing section including the housing and other components.

[0055] As shown in Figures 2(a), 2(b), and 2(c), the easily installed lightning suppression device X according to this embodiment has two types of moving mechanisms 4, which are referred to as a first moving mechanism P and a second moving mechanism Q. 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 pressing plates 44. On the other hand, the second moving mechanism Q has a rotating shaft 41, a pair of rolling elements 42, an axle box 45, and a rudder section 46.

[0056] The rotating shaft 41 is a cylindrical member that is provided in common to the first moving mechanism P and the second moving mechanism Q and connects each rotating part, and is connected to the rolling elements 42, bearings 43, pressure plate 44, and axle box 45.

[0057] The rolling body 42 is provided in common to the first moving mechanism P and the second moving mechanism Q, is connected to an axis concentric with the rotating shaft 41, and is a disk-shaped or cylindrical member that rotates in contact with the ground G to easily move the frame body 3. Examples of the rolling body 42 include a tire, a trailer, a wheel, 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 bodies 42 is longer than the short side of the frame body 3. Furthermore, it is preferable that the diameter of the rolling bodies 42 is about twice the length in the height direction of the vertical frame 31. With this 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 bottom surface of the frame body 3.

[0059] The bearing 43 is a general bearing in which a fixed-side annular member and a rotating-side annular member are combined via a rotating body, and two bearings are provided concentrically with the rotating shaft 41 and inside the rolling body 42 with a predetermined gap therebetween. In this embodiment, in order to support all of the loads of the lightning suppression device main body 1, the support body 2, and the frame body 3 with a small number of parts, a radial roller bearing is shown in Figures 2(b) and 2(c). However, this may be changed as appropriate to a ball bearing, thrust bearing, or the like, depending on the environment in which the simply-installed lightning suppression device X is moved.

[0060] The presser plates 44 are flat plate-shaped members fixed concentrically with the rotating shaft 41 adjacent to the bearings 43, and prevent the bearings 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 part 37, the bearing 43 and the pressing plate 44 fit into the recess 371. At this time, a stopper or the like for holding the bearing 43 so as not to come off may be provided on the recess 371 side. With this configuration, the first moving mechanism P can be easily attached and detached from the frame 3.

[0062] 2(b), the second movement mechanism Q has a rotation shaft 41 that is shorter than the short side of the frame body 3 in the horizontal direction, and the diameter of the pair of rolling elements 42 is smaller than the height from the ground G to the bottom surface of the frame body 3 when the first movement mechanism P is attached to the frame body 3. With this configuration, the second movement mechanism Q can be attached inside the frame body 3.

[0063] The axle box 45 is a box-shaped or cylindrical assembly located at the center of the second moving mechanism Q, particularly between the pair of rolling bodies 42, and includes a bearing concentric with the rotating shaft 41, a housing which covers the bearing, and a hole for mounting the rudder section 46.

[0064] The rudder section 46 is a member 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 section 461 and a control stick 462. With this configuration, when moving the frame body 3, the traveling direction can be easily changed by human power.

[0065] The transmission part 461 is a columnar member that passes through the insertion part 372, with its lower end inserted into the hole of the axle box 45, and its upper end fixed to the control stick 462. The lower end of the transmission part 461 and the hole of the axle box 45 may have any cross-sectional shape other than a circle, in other words, an ellipse, a sector, a polygon, a wedge, or the like, as long as there is a portion to be engaged. Furthermore, the transmission part 461 has a cross-section with a slightly smaller radius than the insertion part 372, which allows it to rotate easily with respect to the frame 3.

[0066] The control stick 462 is a rod-shaped member that is fixed to the upper end of the transmission unit 461 and extends horizontally and away from the frame body 3. When the user holds the control stick 462 in his / her hand and rotates it around the transmission unit 461, the second movement mechanism Q is easily rotated with a small force, and the traveling direction of the frame body 3 is changed.

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

[0068] The easily-installed lightning suppression device X according to this embodiment may have the following configuration. However, the configuration shown below is merely an example, and the presence or absence of the configuration can be determined arbitrarily unless otherwise specified.

[0069] <Example of change> The frame 3 is provided with a grip that the user can hold by hand. This grip is made of an insulating material (e.g., rubber, urethane, etc.) that is flexible enough to conform to the shape of a human hand, and is preferably configured to be wrapped around the upper edge of the vertical frame 31 or the vicinity of the upper end of the protruding portion 36. With this configuration, when the user applies force to the frame 3 to move it, no extra force is required, and the user can easily move the easily installed lightning suppression device X to a desired location.

[0070] The bottom plate 32 has one or more holes at each location in the storage section 311 formed together with the upright frame 31. With this configuration, even if water gets into the storage section 311 due to rain or the like, it can be easily drained.

[0071] The frame body 3 may have a conductive cable that can be stored and drawn out. This conductive cable is a conductive and linear member electrically connected to the conductive material portion of the frame body 3, and is drawn out from the frame body 3 placed on the ground G at the installation location to assist the grounding state by the upright 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 airplane parking area), metal members (such as rebars) are embedded in the ground, so that the lightning suppression device main body 1 can be grounded more stably by connecting a conductive cable to the metal members.

[0072] In the movement mechanism 4, the rolling elements 42 provided on the first movement mechanism P and the second movement mechanism Q may all have the same diameter. With such a configuration, it is possible to reduce the number of types of parts constituting the movement mechanism 4. Even in this case, as in FIG. 2(a), the first movement mechanism P is attached with the bearing 43 fitting into the recess 371, and the second movement mechanism Q is attached so as to be contained between the bottom plate 32 and the ground G. Therefore, when the frame body 3 moves, the entire frame body 3 is tilted with respect to the ground G so that the second movement mechanism Q side is upper.

[0073] Hereinafter, a method for carrying out the present embodiment will be described in detail with reference to the drawings. Note that the method for carrying out the present embodiment will be described in detail with reference to the drawings. The method for carrying out the present embodiment will be described in detail with reference to the drawings. Note that the method for carrying out the present embodiment will be described in detail with reference to the drawings.

[0074] <Method of implementation> When the easily-installed lightning suppression device X is not in use, the user removes the moving mechanism 4 from the frame 3 as shown in Fig. 3(a), and stores the lightning suppression device main body 1 and the divided support body 2 in the storage section 311 as shown in Fig. 5 (storage process). In particular, when there are multiple easily-installed lightning suppression devices X, the frames 3 containing the respective parts are stacked in the height direction for storage as shown in Fig. 3(c). This minimizes the space required for storage when not in use, making it possible to effectively utilize the space, even at a site where multiple easily-installed lightning suppression devices X are required.

[0075] When using the easily installed lightning suppression device X, the user removes the frame 3 from the top as shown in Fig. 3(c) using a forklift, a handlift, or by manual labor by multiple people, and places it on the ground G together with the moving mechanism 4. After that, the user attaches the moving mechanism 4 to the frame 3 in the reverse order to the state shown in Fig. 3(a).

[0076] When the user installs the moving mechanism 4 on the frame body 3, he or she first uses a jack to lift the hoist 35 side of the frame body 3, slides the portion between the rolling bodies 42 of the first moving mechanism P therein, and places the recessed portion 371 on the bearing 43 and the pressing plate 44 to fit them. 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 installs the second moving mechanism Q (moving mechanism installation process). Here, first, the insertion portion 372 is passed through the transmission portion 461, and the lower end of the transmission portion 461 protruding from the lower side of the frame body 3 is inserted into the axle box 45 to connect it. After that, the user removes the jack and moves the frame body 3 to a desired location (transport process).

[0077] When moving the frame body 3, the user applies force manually to the vertical frame 31 and the protruding portion 36, and operates the rudder portion 46 to appropriately change the direction of travel. After moving the frame body 3 to the desired location, the user removes the moving mechanism 4 from the frame body 3 in the reverse order to the above (detachment process), and places the frame body 3 on the ground G and presses it against it (ground contact process).

[0078] Next, the user takes out the support body 2 and the lightning suppression device main body 1 housed in the housing section 311. After that, as shown in Fig. 6(a), the user connects the main support poles 21 in series (coaxially), inserts one end of the pole into the laid-over insertion section 331 and fixes it, attaches the lightning suppression device main body 1 to the other end, and also assembles the suspension pole 23 and the pulley 231, and inserts it into the suspension pole mounting section 34 and fixes it. Furthermore, the user extends the wire W from the hoisting machine 35 and hangs it on the pulley 231, and connects the tip of the wire W to the main support pole 21, particularly the connection flange 211.

[0079] Thereafter, the user operates the hoist 35 to raise the main support column 21 as shown in Fig. 6(b). Then, when the main support column 21 stands upright in the height direction as shown in Fig. 7(a), the user stops the hoist 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 column 23 to obtain the state shown in Fig. 7(b) (supporting process).

[0080] When the user removes the easily-installable lightning suppression device X, the user dismantles and stores the lightning suppression device main body 1 and the support body 2 in the reverse order to the above, and moves the frame body 3 to a storage location.

[0081] Hereinafter, a simply-installed lightning suppression device X according to a second embodiment of the present invention will be described with reference to the drawings. Note that the same components as those in the first embodiment will be designated by the same reference numerals and will not be described.

[0082] Second Embodiment In this embodiment, the bottom plate 32 is provided with a bottom lower portion 321 as shown in Figures 8(a), 8(c), 9(a) and 9(c). The bottom lower portion 321 is a plate-like member that is thicker in the downward direction than the bottom plate 32, and is made of a conductive material. With this configuration, the frame body 3 can be reliably brought into contact with the ground G regardless of the configuration of the movement mechanism mounting portion 37 described later.

[0083] The first moving mechanism P has a rotating shaft 41, and a rolling element 42 and an axle box 45 fixed to the rotating shaft 41, and the second moving mechanism Q has a rotating shaft 41, and a rolling element 42 and an axle box 45 fixed to the rotating shaft 41, similar to the first moving mechanism P, and further has a steering section 46. In this embodiment, 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 it is preferable that two rolling elements 42 are provided on either side of the axle box 45. Furthermore, the first moving mechanism P is provided at two locations near the corners of the frame 3 close to the hoist 35, and the second moving mechanism Q is provided at two locations near the corners of the frame 3 close to the insertion part 372.

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

[0085] Here, in the form shown in Figures 8(a), 8(b), and 8(c), the shaft joint portion 373 for the moving mechanism is configured to be provided outside the mounting positions of the first moving mechanism P and the second moving mechanism Q during movement, in other words, the first moving mechanism P and the second moving mechanism Q rotate from their positions during movement toward the outside of the frame body 3, and the lower part of the bottom 321 comes into contact with the ground G.

[0086] On the other hand, in the form shown in Figures 9(a), 9(b), and 9(c), the shaft joint portion 373 for the moving mechanism is configured to be provided inside the mounting positions of the first moving mechanism P and the second moving mechanism Q during movement, in other words, the first moving mechanism P and the second moving mechanism Q rotate from their positions during movement toward the inside of the frame body 3 and are stored inside the frame body 3, and the lower bottom portion 321 comes into contact with the ground G.

[0087] Either of the above two types of configurations may 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 touched down with a simpler operation.

[0088] Hereinafter, a method of implementing this embodiment will be described in detail with reference to the drawings. The implementation method described below is an example, and the implementation method is not limited to this, and the order of the implementation may be changed. Note that the same reference numerals are used for the same methods as those in the first embodiment, and the description thereof will be omitted.

[0089] <Method of implementation> In the simple installation type lightning suppression device X according to this embodiment, when not in use or when installed, the moving mechanism 4 has the rolling body 42 facing upward and the bottom lower part 321 in contact with the ground G as shown in FIG. 8(c) or FIG. 9(c). When moving the frame body 3 to a desired location from here, the user rotates the first moving mechanism P and the second moving mechanism Q for the moving mechanism shaft joint part 373 to switch to a state in which only the rolling body 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 the state is transitioned to a state in which it is not in use or the lightning suppression device main body 1 is to be installed, the user rotates the first moving mechanism P and the second moving mechanism Q for the moving mechanism shaft joint part 373 in the opposite direction to the above, and switches to a state in which the rolling body 42 faces upward and the bottom lower part 321 is in contact with the ground G as shown in FIG. 8(c) or FIG. 9(c) (rotation process).

[0090] Hereinafter, a simplified installation type lightning suppression device X according to a third embodiment of the present invention will be described with reference to the drawings. Note that the same components as those in the first and second embodiments are designated by the same reference numerals and will not be described.

[0091] Third Embodiment As shown in FIG. 10(a) and FIG. 10(b), in this embodiment, the protruding portion 36 is configured in a cylindrical shape and further includes an expandable and contractible extension portion 361. The extension portion 361 is a columnar member that is expandable in the direction from the frame body 3 to the ground G, and is stored inside the cylinder of the protruding portion 36 when not in use. The expandable length of the extension 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 this configuration, when the easily installed lightning suppression device X is used, the protruding portion 36 can be extended and brought into contact with the ground G, and the first electrode body 11 of the lightning suppression device main body 1 can be easily grounded. Furthermore, it is no longer necessary to attach and detach the moving mechanism 4, and the easily installed lightning suppression device X can be installed more efficiently.

[0092] Hereinafter, a method for implementing this embodiment will be described in detail with reference to the drawings. The method for implementing this embodiment is merely an example, and the method for implementing this embodiment is not limited to this example, and the order of the steps may be changed. Note that the same reference numerals will be used to refer to the same methods as those in the first and second embodiments, and the description thereof will be omitted.

[0093] <Method of implementation> When installing the easily installed lightning suppression device X according to this embodiment at a desired location, the user extends the expandable portion 361 downward from the state of the frame body 3 shown in FIG. 10(a) as shown in FIG. 10(b) and abuts its tip against the ground G (extension step). At this time, it is sufficient that both the moving mechanism 4 and the expandable portion 361 are in contact with the ground G. However, as shown in FIG. 10(b), the moving mechanism 4 may be lifted from the ground G and only the expandable portion 361 may be in contact with the ground G. In this case, the user uses a jack to lift the frame body 3. As a result, all the weight of the easily installed lightning suppression device X is concentrated on the expandable portion 361, so that the expandable portion 361 is more stably pressed against the ground G.

[0094] Hereinafter, a simplified installation type lightning suppression device X according to a fourth embodiment of the present invention will be described with reference to the drawings. Note that the same components as those in the first, second and third embodiments will be designated by the same reference numerals and will not be described.

[0095] Fourth Embodiment 11(a) and 11(b), in this embodiment, the frame body 3 has an expanded ground section 38. The expanded ground section 38 is a member made of a conductive material including a movable beam storage section 381, a movable beam 382, ​​and an adjustment tool 383, and expands the contact area of ​​the frame body 3 with the ground G.

[0096] The movable beam storage section 381 is a pair of flat plate-like members provided along the outer periphery of the vertical frame 31, and sandwiches the movable beam 382 in the height direction. In Fig. 11(a) and Fig. 11(b), the movable beam storage section 381 is configured like a fin protruding from the side of the vertical frame 31, but when the vertical frame 31 is configured of H-beam steel, the internal space of the U-shaped cross section generated by the web and flange can be treated as the movable beam storage section 381. In addition, the movable beam storage section 381 has a joint section to which the movable beam 382 can be attached.

[0097] The movable beam 382 is a columnar member that is rotatably attached to the movable beam storage section 381 and can be expanded horizontally and further outward from the outer periphery of the vertical frame 31. In Fig. 11(a) and Fig. 11(b), the movable beam 382 rotates on a horizontal plane around a joint section (rotation axis) provided in the movable beam storage section 381, and expands in the short side direction of the frame body 3. With this configuration, the area occupied by the frame body 3 can be reduced when moving or not in use, and the stability of the entire simply-installed lightning suppression device X can be improved when the lightning suppression device main body 1 and the support body 2 are installed upright.

[0098] The adjustment tool 383 is a box-like or plate-like member disposed under the tip of the deployed movable beam 382, ​​and electrically connects the movable beam 382 to the ground G. In Fig. 11(a) and Fig. 11(b), the height of the adjustment tool 383 is configured to be approximately equal to the distance from the lower surface of the movable beam 382 to the ground G in a state in which the moving mechanism 4 is attached, but the height may be set to match the distance from the lower surface of the movable beam 382 to the ground G in a state in which 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 body 3 is configured to be grounded simultaneously by both the bottom plate 32 and the adjustment tool 383. With such a configuration, the frame body 3 can be grounded easily and stably.

[0099] The easily-installed lightning suppression device X according to this embodiment may have the following configuration. However, the configuration shown below is merely an example, and the presence or absence of the configuration can be determined arbitrarily unless otherwise specified.

[0100] <Example of change> As a modification of the above-described deployable grounding section 38, there is a configuration in which the movable beam 382 is slidably attached to the movable beam storage section 381. In this case, the movable beam storage section 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 configuration of the protruding section 36 and the expandable section 361 shown in the third embodiment is provided in the horizontal direction. As a result, the movable beam 382 is stored during movement or when not in use, and when the lightning suppression device main body 1 and the support body 2 are in an upright position, the tip of the movable beam 382 is placed on the adjustment tool 383 and the frame body 3 is installed as described above.

[0101] Hereinafter, a method for implementing this embodiment will be described in detail with reference to the drawings. The implementation method described below is an example, and the implementation method is not limited to this, and the order of the implementation may be changed. Note that the same reference numerals are used for methods similar to those of the first, second, and third embodiments, and the description thereof will be omitted.

[0102] <Method of implementation> When installing the easily-installable lightning suppression device X according to this embodiment at a desired location, the user deploys the movable beam 382 in the horizontal direction as shown in FIG. 11(b), and further inserts the adjustment tool 383 under the movable beam 382 to electrically connect the movable beam 382 to the ground G. FIG. 11(b) shows a state in which the deployed grounding section 38 is handled without removing the moving mechanism 4, but the user may detach the moving mechanism 4 from the frame body 3 (detachment step) and ground the movable beam 382 with a thinner adjustment tool 383. This increases the horizontal installation area of ​​the frame body 3, and enables the lightning suppression device main body 1 and the support body 2 to be supported more stably. In addition, the frame body 3 comes into contact with the ground G over an area that is the sum of the bottom surface of the bottom plate 32 and the bottom surface of the adjustment tool 383, so that the first electrode body 11 can be grounded more stably.

[0103] Hereinafter, a simple installation type lightning suppression device X according to a fifth embodiment of the present invention will be described with reference to the drawings. Note that the same components as those in the first, second, third and fourth embodiments will be designated by the same reference numerals and will not be described.

[0104] Fifth embodiment Figures 12(a) and 12(b) are respectively a right side view and a front view showing a frame body 3 capable of transporting the easily installed lightning suppression device X of this embodiment, a moving mechanism 4 attached to the frame body 3, and a power unit 5, and Figure 12(c) is an enlarged view showing the configuration of the moving mechanism 4 in Figure 12(b) and each related part.

[0105] As shown in Figures 12(a) and 12(b), the frame 3, and particularly the moving mechanism mounting portion 37, is provided with an intermediate link 374 that connects to the second moving mechanism Q. In addition to the rotating shaft 41, rolling elements 42, axle box 45, and rudder portion 46, the second moving mechanism Q includes a brake 47, and is further provided with a power unit 5.

[0106] 12(a), in order for the second moving mechanism Q to secure a space for installing the power unit 5, the height from the bottom plate 32 to the ground G may be higher than that of the easily installed lightning suppression device X according to other embodiments. In this case, the frame 3 according to this embodiment is provided with a bottom lower portion 321, and a space for the second moving mechanism Q is secured like a notch.

[0107] The intermediate link 374 is a member that connects the second movement mechanism Q to the vertical frame 31, and includes a flat plate-like member or a column-like member that is rotatably connected by an axis joint. With this configuration, even if the vertical frame 31 has a thickness in the height direction, the second movement mechanism Q can be bounced up to the upper side of the vertical frame 31, and the frame body 3 can be easily grounded. In addition, it is preferable that the vertical frame 31 in this embodiment is configured to have a notch in which the intermediate link 374 can be accommodated. With this configuration, a space for the second movement mechanism Q can be secured by the size (width, thickness, etc.) of the intermediate link 374.

[0108] The frame 3 has a movement mechanism pulley 39 along the side near the second movement mechanism Q. The movement mechanism pulley 39 is a general pulley used by hanging a wire W, and in this embodiment, it is used by hanging the wire W extending from the hoist 35 when pulling the second movement mechanism Q to the upper side of the vertical frame 31. At this time, as shown in Figures 12(b) and 12(c), the movement mechanism pulley 39 is provided at a position shifted from the center of the frame 3. This prevents the wire W from the hoist 35 from interfering with the main support column attachment part 33, the suspension column attachment part 34, and the rudder part 46.

[0109] The brake 47 is a braking device provided on the second moving mechanism Q, and stops the rotation of the rotating shaft 41 by operating a handle. With this configuration, the frame body 3 can be easily braked and stopped in principle during movement.

[0110] The power unit 5 has 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 an electrical input into a rotational motion output, and its output shaft is connected to the rotation shaft 41. This causes the rotation shaft 41 to rotate by the electric motor 51. A speed reducer is provided between the output shaft of the electric motor 51 and the rotation shaft 41 (or the rolling element 42), and the rotational motion generated by the electric motor 51 is appropriately reduced in speed before being transmitted to the rolling element 42. With this configuration, the frame 3 can be moved by self-propelling. Examples of the speed reducer include a planetary gear mechanism.

[0112] The electric motor 51 may be provided integrally with the rolling body 42. In this configuration, by employing a wheel motor, the size of the entire second moving mechanism Q can be reduced, and in addition, the weight imbalance of the entire easily-installed lightning suppression device X can be reduced.

[0113] The motor support 52 is a member including a beam provided between the rolling elements 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 the beam is connected to a column that connects the axle box 45 and the rudder 46, and rotates in the horizontal direction together with the rotating shaft 41, etc., by operating the rudder 46.

[0114] The battery 53 is a battery (which may be a primary or secondary battery) that generates a voltage for operating the electric motor 51. Since the present invention is intended for use outdoors, as shown in Figs. 12(a) to 12(c), a configuration in which the battery is housed in a housing and a circuit is formed with the electric motor 51 via an electric cable 54 is preferable. Also, the housing that houses the battery 53 is preferably provided with a switch or a port for receiving electromagnetic waves or the like on its surface. With such a configuration, the user can easily operate the power supply from the battery 53 by operating a switch or a remote control.

[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 typical wiring whose surface is covered with an insulating material. In this embodiment, as shown in Fig. 12(a) to Fig. 12(c), it is preferable that the electric cable is provided in a slightly loose state rather than in a tensioned state. This configuration can accommodate the rotation of the electric motor 51 caused by the operation of the rudder section 46, and can also avoid the risk of the wire breaking due to pressure contact with the frame 3.

[0116] The surface of each part of the power unit 5 is preferably covered with an insulating material. With such a configuration, the entire power unit 5 is electrically isolated from each conductor part related to the grounding of the lightning suppression device main body 1, thereby preventing failure.

[0117] 13(a) to 13(c) are right side views showing the state when the frame body 3 is grounded, 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 and jumps up to the upper side of the vertical frame 31, so that the frame body 3 can contact the ground G. At this time, the wire W is connected to any of the parts of the second moving mechanism Q that can rotate below the intermediate link 374 (for example, the axle box 45, the electric motor 51, and the motor support 52), and is hung on the moving mechanism pulley 39 and wound up by the hoist 35, so that the entire second moving mechanism Q is pulled up to the upper side of the vertical 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, a method of implementing this embodiment will be described in detail with reference to the drawings. The implementation method described below is an example, and the implementation method is not limited to this, and the order of the steps may be changed. Note that the same reference numerals are used for methods similar to those in the first, second, third, and fourth embodiments, and the description thereof will be omitted.

[0119] <Method of implementation> Figure 13(a) shows the frame body 3 and second movement mechanism Q with the first movement mechanism P removed. When removing the first movement mechanism P from the frame body 3, the user uses the jacks 6 to lift and support the frame body 3. At this time, the user lifts the frame body 3 with the multiple jacks 6 so that the second movement mechanism Q is separated from the ground G. The user then pulls out the rudder section 46 from the axle box 45 to remove it.

[0120] Next, the user pulls out the wire W from the hoist 35, hooks the wire W on the moving mechanism pulley 39, and attaches the tip of the wire W to an appropriate location (a part that can rotate below the intermediate link 374) of the second moving mechanism Q. Thereafter, 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 up to the upper side of the vertical frame 31 according to the movable range of the intermediate link 374.

[0121] 13(c), after the entire second movement mechanism Q is pulled up above the vertical frame 31, the rolling body 42 is placed on the upper surface of the vertical frame 31 or on the housing section 311. At this time, the user supports the second movement mechanism Q by placing a cushioning material between the second movement mechanism Q and the frame body 3. This allows the second movement mechanism Q, particularly the rolling body 42, to be handled without applying shock to it. An example of this cushioning material is a column provided with a shock absorbing material (shock absorber).

[0122] Finally, the user removes the wire W from the second moving mechanism Q, checks that the electrical cable 54 is not interfering with other parts or getting tangled, and then retracts the jack 6 to place the frame 3 on the ground G.

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

[0124] Hereinafter, a simple installation type lightning suppression device X according to a sixth embodiment of the present invention will be described with reference to the drawings. Note that the same components as those in the first, second, third, fourth, and fifth embodiments will be designated by the same reference numerals and will not be described.

[0125] Sixth Embodiment As shown in Fig. 14(a), Fig. 14(b), Fig. 15(a), and Fig. 15(b), the easily installation type lightning suppression device X according to this embodiment includes a lightning suppression device main body 1, a support body 2, and a frame body 3. The difference from the above-mentioned embodiment is that the moving mechanism 4 and the power unit 5 are not included. With this configuration, the number of parts of the easily installation type lightning suppression device X can be reduced, and it can be transported and installed at a desired location.

[0126] 15(a) and 15(b) show the state in this embodiment in which the lightning suppression device main body 1 is erected on the frame body 3 by the support body 2. At this time, the bottom surface of the frame body 3 of the lightning 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 is more stably pressed against the ground G, and the grounding state can be maintained well. In addition, as a result, even if the wind hits the lightning suppression device main body 1 and the support body 2 in the horizontal direction, the lightning suppression device main body 1 does not easily fall over, and the entire simply-installed lightning suppression device X can withstand and support strong winds.

[0127] The frame 3 is preferably configured to have 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 on which the simple installation type lightning suppression device X is installed is not necessarily flat and may include unevenness. For example, the concrete paved surface of an airplane parking area or the like also has slight unevenness. In this case, the contact area between the frame 3 and the ground G becomes smaller than the area of ​​the bottom surface of the frame 3 or the bottom plate 32, and the area for grounding the lightning suppression device main body 1 becomes smaller. The adjustment member may be configured to compensate for this and to further expand the contact area with the ground G determined by the vertical frame 31 outward. In addition, the adjustment member may be in any form as long as it is possible to adjust the length in the height direction shown in each figure. Below, a preferred example of the configuration of the adjustment member is given.

[0128] 16(a), the frame body 3 is provided with an expandable / contractable section 361 that is expandable / contractable in the height direction, particularly toward the ground G, as one form of an adjustment member. Similar to the expandable / contractable section 361 shown in the third embodiment, the expandable / contractable section 361 is provided with a columnar member that can be stored in the cylindrical protrusion 36, and a flat plate-shaped member at the end on the ground G side. With this configuration, the expandable / contractable section 361 extends toward the gap between the frame body 3 and the ground G, and the contact area can be easily enlarged in the portion where the vertical 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 adjustment tool 383 that can be inserted into the gap between the lower surface of the frame body 3 (the lower surface of the vertical frame 31 or the bottom plate 32) and the ground G as another form of the adjustment member. The adjustment tool 383 at this time is a thin plate-like member that can be inserted into the gap between the lower surface of the frame body 3 and the ground G, unlike the fourth embodiment. In addition, the adjustment tool 383 may be of multiple types with different thicknesses, sizes in the surface direction, or shapes. As a result, multiple types of adjustment tools 383 can be used in appropriate combination 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. In addition, the adjustment tool 383 in this form may be of a shape that is basically flat and is folded in a wave shape in the thickness direction. As a result, the adjustment tool 383 is pressed against both the frame body 3 and the ground G by the principle of a leaf spring, and a more stable grounding state can be achieved.

[0130] As shown in FIG. 16(c), the frame 3 has an expanded ground section 38 as another embodiment of the adjustment member. The expanded ground section 38 includes a movable beam storage section 381, a movable beam 382, ​​and an adjustment tool 383, as in the fourth embodiment. In this embodiment, the movable beam storage section 381 is configured to utilize the internal space of the U-shaped cross section generated by the web and flange of the H-shaped steel that forms the vertical frame 31. The movable beam 382 is connected to the movable beam storage section 381 by a shaft joint that extends in the height direction, and is a columnar member that can rotate horizontally from the movable beam storage section 381. Furthermore, the adjustment tool 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 enables the contact area between the frame 3 and the ground G to be expanded outward. With this configuration, the grounding of the lightning suppression device main body 1 can be more stable, and the short side direction in the horizontal direction of the frame body 3 can be easily expanded, thereby improving the stability when the easily installed lightning suppression device X is installed.

[0131] Hereinafter, a method for carrying out the present invention will be described in detail with reference to the drawings. Note that the method for carrying out the present invention will be described as an example, and the method for carrying out the present invention is not limited to this example, and the order of the steps may be changed.

[0132] <Method of implementation> When transporting the easily installation type lightning suppression device X according to this embodiment to an installation site, the user transports the frame body 3, which contains the lightning suppression device main body 1 and the support body 2 in the housing section 311, to the desired site manually or by placing it on the bed of a transport vehicle (truck, etc.). This does not require special equipment, etc., and allows the easily installation type lightning suppression device X to be transported easily, and does not require the attachment and detachment of parts for transportation, reducing the number of work steps required for transporting the easily installation type lightning suppression device X.

[0133] Next, the user places the transported frame body 3 on a desired ground surface G, and, if necessary, uses an adjustment member to expand the contact area between the frame body 3 and the ground surface G (contact surface expansion process). After that, the user stands the lightning suppression device main body 1 and the support body 2 in the same manner as in the other embodiments. When removing the easily installed lightning suppression device X, the above steps are carried out in reverse. [Explanation of symbols]
