Description

Technical Field

[0001] The present invention relates to charging equipment, mainly to charging equipment for electric vehicles (hereinafter referred to as EVs).

Background Art

[0002] There are cases where electrical equipment such as chargers and transformers is installed outdoors. Especially in recent years, with the popularization of EVs, the opportunities for installing EV chargers outdoors have been increasing. When installing such electrical equipment as chargers outdoors, a method of installing a base of hard and heavy concrete blocks and fixing the electrical equipment thereon is generally adopted. For example, Patent Document 1 discloses a fixing method characterized by including steps of: arranging each of a plurality of support members for supporting the housing from below at a position corresponding to a fixing portion of a bottom cover in a state where the detachable bottom cover is removed from the bottom surface of the housing; attaching the fixing portion to each of the arranged plurality of support members; and attaching the bottom surface of the housing to the bottom cover to which the fixing portion has been attached to each of the plurality of support members.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The fixing method described in Patent Document 1 requires complex processes such as positioning support members and attaching fixing parts at the site where the electrical equipment is installed. Furthermore, when electrical equipment is fixed using this fixing method, cables such as power lines connected to the electrical equipment are exposed and are often susceptible to damage from wildlife. In addition, while burying cables underground is a common practice to mitigate such damage, such cable burial work requires large-scale civil engineering work using specialized equipment, making the installation of electrical equipment even more difficult. [Means for solving the problem]

[0005] As a result of diligent research by the inventors, it was discovered that the above problems can be solved by EV charging equipment fixed to a fixed base of a specific structure, and thus the present invention was completed. In the following explanation, charging equipment may sometimes be described as electrical equipment, a broader concept. This is because, although this invention was completed through the study of charging equipment for EVs, which are expected to become the mainstream eco-cars in the future, it is not limited to charging equipment and can be broadly applied to electrical equipment as well. On the other hand, it can also be applied to hydrogen supply equipment in hydrogen fueling stations for hydrogen-powered vehicles.

[0006] [1] That is, the present invention relates to a fixed base having a base member, a spacer member, a cover member and a fixing member, The base member has a spacer member on its upper side, The spacer member has a cover member on its upper side, There is a space inside the base member, spacer member and cover member, The charging device cable is located in that space. This is a car charging system characterized in that the base is fixed to the mounting surface by anchors, and the car charging device is fixed to the base by anchors. [2] The present invention is a vehicle charging equipment as described in [1] above, characterized in that the fixing member penetrates the cover member from above the base member to fix the charging device. [3] The present invention is a vehicle charging device according to [1] or [2] above, characterized in that the fixing member supports the charging device. [4] The present invention is a charging device according to [1] or [2], characterized in that a member having a height adjustment function is installed on a fixed base. [5] The present invention is a charging equipment according to [1] or [2], characterized in that the charging equipment has a support column portion and the charging device is fixed to the support column portion with a fixing member. [6] The present invention is a charging device according to [1] or [2], characterized in that the cable is arranged without touching the ground. [7] The present invention is a charging device according to [1] or [2], characterized in that the cable is arranged horizontally in the space. [8] The present invention is a charging device according to [1] or [2], characterized in that a plurality of units (2, 3, 4, 5, 6, 7, 8, 9, 10 units, etc.) are installed on the fixed base. [9] The present invention is a charging system according to [8], characterized in that a cable for connecting multiple charging devices is connected through the space.

[10] The present invention is a charging device according to [1] or [2], characterized in that it does not require the burial of cables for the electrical equipment. [Effects of the Invention]

[0007] The mounting base used in this invention can be assembled in a factory or similar facility and then transported to the site for installation, making installation easy. Furthermore, since there is no need for large-scale civil engineering work such as cable burial during installation, the installation of electrical equipment, specifically EV charging equipment, can be carried out much more easily and quickly than when using conventional mounting bases. In addition, because the mounting base used in this invention has a simple structure, the charging device can be easily attached and detached. Furthermore, the charging equipment can be installed with a strong connection to the mounting surface using anchors. Therefore, there is no need to make the base heavy, and a lightweight mounting base can be used, for example, one with a ladder structure and reduced thickness. The advantage of making the mounting base lighter is extremely significant in terms of transportation and installation. [Brief explanation of the drawing]

[0009] Preferred embodiments of the present invention will be described with reference to the drawings. The present invention is a charging device in which a fixed base, as described below, is fixed to an installation surface with arbitrary anchors. It goes without saying that the present invention is not limited to the following embodiments and aspects, and various modifications are possible within the technical scope of the present invention. Also, "up and down," "front and back," and "left and right" in this text refer to the directions shown in each drawing.

[0010] Figure 1 shows a specific example of a fixed base (hereinafter simply referred to as "fixed base") used in electrical equipment (in this specification, car charging equipment may be simply referred to as "electrical equipment") of the present invention. The fixed base 1 in Figure 1 includes a base member 2 having at least an upper surface, a spacer member 3 installed on the upper surface of the base member 2, a cover member 4 covering at least the spacer member 3 while leaving space around the spacer member 3, and a fixing member 5 protruding substantially vertically from the upper surface of the base member 2 and penetrating the cover member 4 to be exposed to the outside. Further embodiments of the fixed base 1 of the present invention are shown in Figure 7. The fixed base 1 in Figure 7 includes a base member 2 having at least an upper plane, a spacer member 3 installed on the upper plane of the base member 2, and a cover member 4 that covers at least the spacer member 3 while leaving space around it. Holes 23 and 41 are provided in the base member 2 and the cover member 4, respectively, and the centers of the holes 23 in the base member 2 and the holes 41 in the cover member 4, as viewed from the planar direction, coincide. The components will be described in detail below.

[0011] 1. Base member 2 The base member 2 is a member having at least a flat surface on its upper side. The base member 2 is a base that supports the spacer member 3, which will be described later, and is also a base that supports the cables of the electrical equipment fixed to the fixing base 1 so that they do not come into direct contact with the ground. Furthermore, the base member 2 is a member that serves as the foundation for fixing the cover member 4, which will be described later, as needed. The shape of the base member 2 can be adjusted as appropriate according to the terrain of the place where the electrical equipment is to be installed. For example, if the planar shape of the base member 2 is made rectangular as shown in Figures 2(A) to (C), and the place where the electrical equipment is to be installed is flat, the lower side of the base member 2 may be made a flat surface. If the place where the electrical equipment is to be installed is sloped, for example, it may be sloped in the left-right direction and / or in the front-back direction as shown in Figures 2(D) to (E). Also, if there are fine irregularities at the installation site, fine irregularities may be provided on the lower surface of the base member 2 (not shown). Furthermore, the shape of the base member 2 as viewed from the planar direction may be a polygon including a triangle, a rectangle, a square, a pentagon, and a hexagon, or a circle including an ellipse. Also, the shape of the base member 2 as viewed from the planar direction may be a shape that has length in the front-to-back or left-to-right direction, for example, a rectangle or an ellipse. The upper side of the base member 2 may have protrusions or indentations (not shown), provided that it has a flat surface that allows for the installation of the spacer member 3, as described later. The base may be a ladder structure base installed on the lower surface of the spacer member, as long as it can support the electrical equipment. In other words, this embodiment has a structure in which the base is bridged with spacer members (which may be referred to as a ladder structure in this specification). In this case, since the members of the ladder structure are the base or have the function of a base, it is not necessarily required to provide a concrete base below them. If the materials that make up the ladder structure are, for example, relatively thin steel frames, then the weight of the base can be reduced.

[0012] The material of the base member 2 is not particularly limited, provided that it can withstand the mass of the electrical equipment to be installed and the spacer member 3 described later. Examples of such materials include metal materials such as iron, steel, and aluminum, glass materials, concrete materials, resin materials such as acrylic, and wood. Among these, concrete is more preferable because it is less affected by the humidity and other environmental factors of the installation site and is relatively easy to process.

[0013] Furthermore, the base member 2 used in the present invention may include a groove 21 on its upper surface and a latching portion 22 that protrudes from near the upper end of the groove 21 toward the center of the groove. Figure 3 shows an example of the form of the base member 2 including the groove 21 and the latching portion 22. As shown in Figures 3(A) to (C), a groove 21 extending in the front-rear direction is provided approximately in the left-right center of the base member 2. In addition, the latching portion 22 protrudes from near the left and right upper ends of the groove 21 toward approximately the left-right center of the groove 21. The groove 21 and the latching portion 22 are used when fixing the fixing member 5 to the base member 2, as will be described later. The shape of the latching portion 22 is not particularly limited as long as it is a shape that allows the fixing member 5 to be fixed using a nut or the like, as will be described later. Furthermore, the groove 21 and the latching portion 22 may be formed by cutting or the like after the base member 2 is manufactured, or a mold may be used to form the groove 21 and the latching portion 22 when forming the base member 2. The shape of the groove 21 when viewed from the planar direction may be a straight line or a bent line, as shown in Figure 3. Similarly, the shape of the groove 21 when viewed from the front may be a polygon, such as a quadrilateral as shown in Figure 3, or a semicircle. The base member 2 having the groove 21 and the latching portion 22 may be used to fix the fixing member 5 as described above, or it may be used to fix the spacer member 3 as described later.

[0014] 2. Spacer member 3 The spacer member 3 is a member installed on the upper plane of the base member 2. By installing the spacer member 3 on the base member 2, a space is secured between the base member 2 and a cover member 4 described later. The material of the spacer member 3 can be appropriately selected on the condition that it can withstand the mass of the electrical equipment installed on the fixed base 1. Examples of such materials include metal materials such as iron, steel, and aluminum, glass materials, concrete materials, resin materials such as acrylic, and wood. Regarding its shape, it can be appropriately adjusted according to the material on the condition that it can withstand the mass of the electrical equipment installed on the fixed base 1 and a space for arranging cables of the electrical equipment can be secured as described later. As a specific shape of the spacer member 3, for example, as shown in FIGS. 4(A) and (B), it may be a rod-shaped member having a length. Also, as shown in FIGS. 4(C) and (D), it may be a plate-shaped member having a thickness with an elliptical planar shape. Furthermore, it may be a rod-shaped member having a length with a shape that can secure more space so that it looks like a "工" character or a "コ" character when viewed from the front direction (a "工" character in FIGS. 4(E) and (F)).

[0015] Incidentally, the spacer member may also be referred to as a connecting member in that it connects the base member and the cover member to form a space for accommodating the cable of the charging equipment, which is a feature of the present invention, and the scope of the present invention is not limited by this name.

[0016] The spacer member (also referred to as a connecting member) can use H-beams or C-beams. It may be arranged to surround the periphery of the base, or may be arranged in a part thereof. For example, when the base member is an object having a three-dimensional structure such as a cube, a rectangular parallelepiped, or a polyhedral structure, it may be arranged to surround all its sides, or may be arranged only on any side that is a part thereof, or on a part of any side. Incidentally, the spacer member may be integrally formed with the base member and / or the cover member described later. The cross-section of the space formed by these three members is not limited. This cross-section is preferably a quadrilateral, including a square. It is also preferably a polygon. It may be a circle or a semicircle. It may also have lines and curves.

[0017] 3. Cover member 4 The cover member 4 is a member that covers at least the spacer member 3 while leaving space around it. The material of the cover member 4 can be appropriately selected, provided that it can withstand the mass of the electrical equipment installed on the fixing base 1. Examples of such materials include metal materials such as iron, steel, and aluminum, glass materials, concrete materials, resin materials such as acrylic, and wood. The shape of the cover member 4 is not particularly limited, provided that it can cover at least the spacer member 3. For example, it may be a plate-shaped member whose shape when viewed from a planar direction is a polygon such as a triangle, square, pentagon, or hexagon, or a circle including an ellipse. The cover member 4 has holes 41 for passing the fixing member 5 through, as will be described later. In addition, the cover member 4 may have holes 41' for passing cables of the electrical equipment fixed to the fixing base 1, if necessary. The holes 41 and 41' can be made in advance, or they can be made after the cover member 4 is fixed to the fixing base 1, as will be described later. Furthermore, by applying an uneven surface to at least the surface of the cover member 4, the possibility of accidents such as workers slipping when fixing the electrical equipment to the fixing base 1 can be reduced.

[0018] 4. Fixing member 5 The fixing member 5 is a member that fixes the charging equipment. Bolts are preferred. The number of bolts used for fixing is not limited. It is preferable to fix it in one place (one bolt in the case of bolts). It is also possible to fix it in multiple places (for example, two, three, four, five, six, seven, or eight bolts). The relative positions of the bolts are not particularly limited. A structure that allows them to be fixed by passing through the cover member is preferred. It is also acceptable if they are fixed without passing through the cover member, but are located on its upper surface (the surface with the electrical equipment to be fixed), and can support the weight of the charging device. As shown in Figure 1, it is also preferable that the member protrudes substantially vertically from the upper plane of the base member 2 and penetrates the cover member 4 to be exposed to the outside. Here, "substantially vertical" means an angle that allows the electrical equipment to be fixed by the fixing member 5 that penetrates the cover member 4. Therefore, it is not only the case that the angle between the plane of the base member 2 and the axial direction of the fixing member 5 is a right angle, but also angles other than vertical that allow the electrical equipment to be fixed by the fixing member 5. The fixing member 5 is a member for fixing the electrical equipment which will be fixed to the fixing base 1 as described later. Specific examples of such a member include, for example, a member for screw fastening such as a bolt, or a member for pin fastening. The material of such a fixing member 5 can be appropriately selected, provided that it can support the electrical equipment installed on the fixing base 1 so that it does not move. Examples of such materials include metal materials such as iron, steel and aluminum, glass materials, concrete materials and resin materials such as acrylic.

[0019] 5. Specific example of the fixed base 1 Figure 1 shows a specific example of the fixed base 1. In the fixed base 1 of Figure 1, two spacer members 3 made of steel H-beams are installed parallel to each other on the upper surface of a base member 2 made of concrete, which has flat upper and lower surfaces. The spacer members 3 are fixed to the base member 2 by fasteners 31 (bolts in Figure 1). A fixing member 5 (bolt in Figure 1), consisting of a shaft portion 51 and a head portion 52, is embedded in the base member 2 with the head portion 52 facing downwards. The shaft portion 51 of the fixing member 5 extends from the upper plane of the base member 2 in a direction substantially perpendicular to the direction of that plane. The base member 2 and the spacer members 3 are surrounded by a cover member 4, and space is secured around the spacer members 3. In Figure 1, the spacer members 3 are surrounded together with the base member 2 by the cover member 4, but the cover member 4 may be used to surround only the spacer members 3. In this case, it is preferable to ensure a space between the cover member 4 and the spacer member 3 sufficient to allow cables such as electric wires of electrical equipment fixed to the base 1, as described later, to pass through. More preferably, as mentioned above, it is preferable that the cover member 4 surrounds the base member 2 and the spacer member 3 together. By doing so, the unevenness of the base 1 is reduced, the overall strength of the base 1 is increased, and accidents such as workers tripping during installation can be avoided.

[0020] In Figure 1, the cover member 4 is made of steel checkered plate with a rectangular planar shape, welded together to form a box shape without a bottom, and is installed by placing it over the base member 2 and spacer member 3. The cover member 4 is fixed to the side of the base member 2 by fasteners 42 (bolts in Figure 1). Note that the fasteners 42 are not used when it is not necessary to fix the cover member 4. The fixing member 5 protrudes outward from a hole 41 made in the cover member 4. A nut 53 is fastened to the shaft portion 51 of the fixing member 5 so that it is located where the inner surface of the cover member 4 and the shaft portion 51 of the fixing member 5 come into contact. By providing the nut 53 as described above, the strength of the cover member 4 near the hole 41 is improved, and the durability against the mass of the electrical equipment when the electrical equipment is fixed to the fixing base 1 can be further improved. In addition, by providing a hook on the top surface of the fixing base 1, it may be made easier to move the fixing base 1 using a rope or the like. Specifically, holes may be drilled through the spacer member 3 and the cover member 4, and the hook may be bolted in place (not shown).

[0021] 6. Specific example of the fixed base 1 (2) Figure 5 shows a more specific example of the fixed base 1. In Figure 5, parts numbered the same as in Figure 1 are described in the same way as in Figure 1 unless otherwise specified. In the example of Figure 5, the concrete base members 2 have a length when viewed from the planar direction, and at least two (three in Figure 5) are arranged in parallel. The spacer members 3 are made of steel, have a length when viewed from the planar direction (H-beams in Figure 5), and are installed perpendicular to the length direction of the base members 2 (two in Figure 5). This configuration makes the mass of the fixed base 1 lighter and reduces the burden on workers when installing the fixed base 1. In Figure 5, the three base members 2 are installed in parallel, but these base members 2 do not necessarily have to be installed in parallel, and their positional relationship can be adjusted as appropriate depending on the installation location. Also, in Figure 5, the spacer members 3 are stretched perpendicular to the base members 2, but this angle does not necessarily have to be perpendicular, and the angle can be adjusted as appropriate depending on the installation location.

[0022] 7. Specific example of the fixed base 1: 3 Figure 6 shows a more specific example of the fixed base 1. In Figure 6, parts numbered the same as in Figures 1 and 5 are described in the same way as in Figures 1 and 5 unless otherwise specified. In the example of Figure 6, a base member 2 having a groove 21 and a latching portion 22 is used as the base member 2 for fixing the fixed member 5 (the middle base member 2 shown in Figure 3(C)). The head 52 of the fixed member 5 (a bolt in Figure 6) is fitted into the groove 21 and latched in place by the latching portion 22. By screwing it in from the opposite side of the head 52 using a nut 54, the latching portion 22 is sandwiched between the head 52 and the nut 54, and the fixed member 5 can be fixed to the base member 2 at the desired position in the groove 21. By using a base member 2 as described above, the position of the fixed member 5 can be adjusted on site according to the conditions of the place where the electrical equipment is to be installed. Furthermore, if the position of the fixing member 5 needs to be adjusted on-site, the position of the fixing member 5 can be determined first, and then a hole 41 can be drilled on-site at a location in the cover member 4 corresponding to the position of the fixing member 5. Also, in Figure 6, the spacer member 3 is fixed to the base member 2, which does not have a groove 21 and a latching portion 22, using a fastener 31. However, the spacer member 3 may also be fixed to the base member 2, which includes a groove 21 and a latching portion 22. In this case, for example, a hole can be drilled in a predetermined location on the spacer member 3, the head of the fastener 31 can be hooked onto the latching portion 22, and the shaft can be passed through the hole in the spacer member 3 and bolted in place to secure it.

[0023] 8. Specific example of the fixed base 1 (4) Figure 7 shows a more specific example of the fixed base 1. In Figure 7, parts numbered the same as in Figures 1, 5, and 6 are described in the same way as in Figures 1, 5, and 6 unless otherwise specified. In the example of Figure 7, instead of a fixed member 5, a hole 23 is made in the base member 2. A fixed member fixing part 24 (a nut in the example of Figure 7) is embedded near the upper end of the hole 23. The center of the hole 23 in the base member 2 and the center of the hole 41 made in the cover member 4 overlap along line α (see Figures 7(B) and (C)). In the example of Figure 7, the fixed member 5 (for example, a bolt) can be inserted into the hole 23 through the hole 41 at the site and fixed using the fixed member fixing part 24 (a nut in the case of Figure 7) (screw fastening in the case of Figure 7).

[0024] 9. Fixing of electrical equipment using the fixing base 1 Figures 8 and 9 show specific examples of fixing electrical equipment EE using the fixing base 1 of the present invention. A hole is made in the bottom of the housing HO of the electrical equipment EE, and the shaft portion 51 of the fixing member 5 protruding from the cover member 4 is inserted into the hole and fastened with a nut 55 (see Figures 8 and 9(A)). At the installation site of the electrical equipment EE, for example, the bottom of the housing HO of the electrical equipment EE can be removed, fixed to the fixing base 1 by fastening the bottom with a nut 55, and then the housing HO can be reassembled to fix the electrical equipment EE to the fixing base 1. Furthermore, by making additional holes 41', 41' in the fixing base 1, the cable CA of the electrical equipment EE can be routed through the inside of the fixing base 1 to the outside. Inside the fixing base 1 of the present invention, at least a space surrounded by the cover member 4 around the spacer member 3 is secured, and the cable CA can be passed through this space. The cable CA is enclosed by the cover member 4 and can also be routed over the base member 2, eliminating the need for burial work and minimizing damage from animals, etc. When removing the electrical equipment EE, it can be easily removed by performing the reverse of the installation procedure. The fixing base 1 of the present invention has a simple structure, making it easy to attach and detach electrical equipment.

[0025] Figure 9(B) shows the configuration when the electrical equipment EE is fixed using the fixing base 1 of Figure 7. In the example of Figure 9(B), the bottom of the housing HO is removed, as in the case of Figure 9(A), and the bottom of the housing HO is fixed to the fixing base 1 by fastening a fixing member fixing part 24 (nut in Figure 9(B)) embedded in the upper part of a hole 23 made in the base member 2 through a hole 41 in the cover member 4, using a fixing member 5 (bolt in Figure 9(B)). After fixing the bottom of the housing HO to the fixing base 1, the housing HO is reassembled in the same way as in the case of Figure 9(A).

[0026] When there are multiple electrical devices to be installed on site (for example, EV chargers, power distribution equipment, and transformers installed in the same location), these multiple electrical devices can be fixed to a single fixing base 1 by increasing the area of ​​the fixing base 1 in the planar direction and increasing the number of fixing members 5 used. By fixing multiple electrical devices to a fixing base 1 with a large area in this way, when connecting individual electrical devices with cables, the cables can be connected through the internal space of the same fixing base 1, eliminating the need for cable burial work. Alternatively, a fixing base 1 can be prepared for each individual electrical device, and each electrical device can be fixed to its respective fixing base 1. In this case, by placing each fixing base 1 close together, the frequency with which the cables connecting each electrical device are exposed to the outside can be minimized. Furthermore, a fixing base 1 without any electrical devices installed can be used as a substitute for conduit for cables, etc.

[0027] Embodiments in which a fixed base has a portion that can be considered a support column, and electrical equipment is fixed thereto by a fixing member, are also within the scope of the present invention. In other words, the claim that the electrical equipment or cover member is a part of the electrical equipment or cover member confirms that the support column is considered to be part of the electrical equipment or part of the cover member and falls within the scope of the present invention. Furthermore, even if the support column is considered a separate component, Claim 1 does not exclude the presence of a support column, and since the component is an open claim, it goes without saying that it falls within the scope of the present invention.

[0028] The present invention is achieved by fixing the mounting base on which the above-mentioned charging device is installed to the mounting surface with anchors. The explanation is as follows.

[0029] The installation surface is not limited as long as the charging equipment can be installed on it. The installation surface may be the ground surface, concrete, asphalt, brick, cobblestone, gravel, wood, or a combination of these. In short, the installation surface is not limited as long as the charging equipment can be fixed and installed with anchors. Furthermore, the installation location is not limited to the surface of the earth; it may also be underground. Regardless of whether it is above or below ground, the mounting base can be secured with anchors, and as long as it is possible to charge a vehicle, the charging equipment of the present invention can be installed on any mounting surface or in any location. The devices to be charged are preferably electric vehicles (EVs), and the present invention is preferably used as an EV charging facility. This is because the cables are thick and the number of eco-friendly EVs is expected to increase in the future. The present invention is useful regardless of the charging speed, whether it is a fast charger, a medium charger, or a slow charger. In particular, the usefulness of the present invention is further increased when installing a fast charger with the thickest cables, or when installing multiple charging devices with many cables on a fixed base. This is because the large internal space of the fixed base allows for easy storage of thick cables and multiple cables, and because the theft of cables, which is more costly if stolen, can be prevented because the cables are housed inside a fixed base with a cover that cannot be easily opened. On the other hand, it can be used not only for EVs but also for vehicles with electric motors and energy storage devices, such as plug-in hybrid vehicles. The vehicle is not limited as long as it is powered by an energy storage device. For example, it can be used to charge electric scooters and electric-assist bicycles. It can also be used in electric tractors. Furthermore, this invention can be used not only for vehicles but also for machines that have rechargeable batteries. For example, it can be the battery itself. In addition, if the charging device is replaced with a filling device, for example, by installing a hydrogen filling device on the fixed base, it can be used as a hydrogen station. The anchors used in this invention are not limited. For example, bolts, screws, screw piles, mega anchors, single-pipe piles, piles of various materials, and wooden piles can be used as long as they can secure the electrical equipment to the installation surface. This makes it possible to eliminate or reduce the risk of movement caused by strong winds or earthquakes. In particular, it is preferable that the base is not a hard and heavy concrete block, but rather a ladder structure connecting two or more spacer members (such as H-beams, C-beams, or steel frames). This is because it reduces weight and simplifies installation. In this case, the anchors used in the present invention are especially useful to prevent the base from shifting due to external factors (such as strong winds or impacts). The anchors used are those that have pull-out strength using frictional force or those that have pull-out strength due to their weight, and are driven into the installation surface by any means. This may be done manually with power tools or a hammer. When the electrical equipment is small and the number of anchors is small, it is preferable to drive in mega anchors using power tools, and when the electrical equipment is large and has multiple charging devices (such as 2, 3, 4, 5, 6, 7, 8, 9, or 10 units), it is preferable to drive in screw piles using heavy machinery.

[0030] Furthermore, the fixing member may also serve as the base, in which case a separate member is not necessarily required as the base. The fixing member, which also functions as a base, is fixed to the installation surface using an anchor. The case in which the spacer member also serves as the base is also within the scope of the present invention. These cases (where the base and the fixing member are the same, or where the spacer member is the same as the base) also satisfy the requirements of the present invention, which state that there is a base, a fixing member, and a spacer member.

[0031] The present invention may also be installed using a member with a height adjustment function on the installation surface and the charging equipment, for example, by using a jack-up member.

[0032] When we say that charging equipment has a support column, it means that, for example, the cover member may have a support column, or the charging device may have a support column.

[0033] The essence of this invention lies in the fact that the mounting base for fixing the charging device has sufficient space inside to house the charging device's electrical cable. Conventional mounting bases are concrete blocks such as rectangular or cubic prisms, and the concrete base must be able to withstand the weight of the charging device, so there is no space inside. In other words, the cable was either buried underground or left exposed above ground. It is also conceivable to house the cable in a duct box or duct pipe to protect it, but this requires extra installation area, and it is not easy to house the cable in a duct pipe. This is especially true when multiple charging devices are installed on the mounting base. From this point of view, the usefulness of this invention increases even more for charging facilities having at least four or more (preferably five, six, seven, eight, nine, eleven, or twelve) charging devices. Furthermore, its usefulness increases even more in the case of fast charging devices with thick electrical cables. This usefulness allows the remarkable effects of this invention (for example, the construction period is remarkably shorter compared to the installation of conventional electrical equipment) to be more fully realized. This is because it eliminates the need to combine a duct box or duct pipe with the mounting base, and also eliminates the need to bury the cables underground.

[0034] Furthermore, a key feature of this invention is that it can be firmly fixed to the installation site using anchors, which makes it an extremely safe device even after many years of use.

[0035] The charging equipment of the present invention can be installed more easily by any means compared to conventionally known charging equipment. [Industrial applicability]

[0036] The charging equipment of the present invention, specifically a vehicle charging device, which uses a fixed base having a specific structure, can be assembled in advance at a factory or the like and then transported and installed on-site. Furthermore, because its structure is not complex, the electrical equipment can be easily attached and detached, significantly reducing the amount of work required at the site where the electrical equipment is installed. This can greatly contribute to industries that require electrical equipment such as charging devices, such as the spread of electric vehicles (EVs). Specifically, charging facilities, whether they are fast-charging facilities, medium-speed charging facilities, or low-speed charging facilities, are extremely useful. Since the cables for charging equipment are thicker than the cables for other general electrical equipment, the present invention is highly useful in this respect. Furthermore, the more cables there are, the greater their usefulness becomes. From this perspective, a fast-charging system with the thickest cables is preferable. Furthermore, the usefulness of this invention increases as the number of charging devices installed on fixed bases such as 4, 5, 6, 7, 8, 10, and 12 increases, including multiple charging equipment with multiple cables, in fast, medium, and low-speed electrical equipment. This invention can be used not only for charging equipment but also for a wide range of electrical equipment. [Explanation of Symbols]
