[Effects of the Invention]

[0006] The electrical equipment fixing base of the present invention is easy to install because it can be assembled in a factory or the like and then transported to the site for installation. Furthermore, since large-scale civil engineering work such as cable burying is not required for installation, the installation work of the electrical equipment can be completed more easily and in a shorter time. Furthermore, since the fixing base of the present invention has a simple structure, it is easy to attach and detach the electrical equipment. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0008] Preferred embodiments of the present invention will be described with reference to the drawings. 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. In addition, the terms "up and down," "front and back," and "left and right" in the text refer to the directions shown in the drawings.

[0009] A specific example of the fixed base for electrical equipment of the present invention (hereinafter simply referred to as "fixed base") is shown in Fig. 1. The fixed base 1 of Fig. 1 includes a base member 2 having a flat surface at least on its upper side, a spacer member 3 installed on the upper flat surface of the base member 2, a cover member 4 that covers at least the spacer member 3 while leaving a space around the spacer member 3, and a fixing member 5 that protrudes substantially vertically from the upper flat surface of the base member 2 and penetrates the cover member 4 to be exposed to the outside. Another example of the fixed base 1 of the present invention is shown in Fig. 7. 7 includes a base member 2 having a flat surface at least on its upper side, a spacer member 3 placed on the flat upper surface of the base member 2, and a cover member 4 that covers at least the spacer member 3 while leaving a space around the spacer member 3, with holes 23 and 41 formed in the base member 2 and the cover member 4, respectively, and the center of hole 23 in the base member 2 overlaps with the center of hole 41 in the cover member 4 when viewed from the planar direction. Each component will be described in detail below.

[0010] 1. Base member 2 The base member 2 is a member having a flat surface at least on its upper side. The base member 2 is a base that supports the spacer member 3 (described later) and also 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. The base member 2 also serves as a base for fixing the cover member 4 (described later) as needed. The shape of the base member 2 can be adjusted appropriately depending on the topography of the location where the electrical equipment is to be installed. For example, as shown in Figures 2(A) to 2(C), the planar shape of the base member 2 may be rectangular, and the underside of the base member 2 may be flat if the installation location of the electrical equipment is flat. Furthermore, if the installation location of the electrical equipment is sloped, the base member 2 may be sloped in the left-right and / or front-to-back directions, for example, as shown in Figures 2(D) to 2(E). Furthermore, if the installation location has small irregularities, the underside of the base member 2 may be provided with small irregularities (not shown). The shape of the base member 2 as viewed from a plane may also be a triangle, a quadrangle including a rectangle, a polygon such as a pentagon or a hexagon, or a circle including an ellipse. The shape of the base member 2 as viewed from a plane may also be a shape that has length in the front-to-back or left-to-right direction, such as a rectangle or an ellipse. The upper side of the base member 2 may have protrusions or irregularities (not shown), provided that it has a flat surface large enough to accommodate the spacer member 3, as will be described later.

[0011] There are no particular restrictions on the material of the base member 2, 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, it is more preferable to use concrete material, as it is less susceptible to environmental influences such as humidity at the installation location and is relatively easy to process.

[0012] The base member 2 used in the present invention may also include a groove 21 on its upper surface and a hook 22 protruding from near the upper end of the groove 21 toward the center of the groove. FIG. 3 shows an example of a base member 2 including the groove 21 and the hook 22. As shown in FIGS. 3(A) to 3(C), the groove 21 extending in the front-rear direction is provided in approximately the center of the base member 2 in the left-right direction. Furthermore, the hook 22 protrudes from near the upper left and right ends of the groove 21 toward approximately the center of the groove 21 in the left-right direction. The groove 21 and the hook 22 are used when fixing the fixing member 5 to the base member 2, as described below. The shape of the hook 22 is not particularly limited as long as it allows the fixing member 5 to be fixed using a nut or the like, as described below. The groove 21 and the hook 22 may be formed by cutting or the like after manufacturing the base member 2, or a mold for forming the groove 21 and the hook 22 may be used when molding the base member 2. The shape of groove 21 when viewed from above may be linear as shown in Fig. 3, or may be a bent line. Furthermore, the shape of groove 21 when viewed from the front may be polygonal, such as a square as shown in Fig. 3, or may be semicircular. Note that base member 2 having groove 21 and hook portion 22 may be used when fixing fixing member 5 as described above, or may be used when fixing spacer member 3 as described below.

[0013] 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 the 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 the cable 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. Further, it may be a rod-shaped member having a length and having a shape that can secure more space so that the shape seen from the front direction looks like a "工" character or a "コ" character (a "工" character in FIGS. 4(E) and (F)).

[0014] 3. Cover member 4 The cover member 4 is a member that covers at least the spacer member 3 while leaving a space around the spacer member 3. The material of the cover member 4 can be selected appropriately, provided that it can withstand the weight of the electrical equipment installed on the fixed base 1. Examples of such materials include metals such as iron, steel, and aluminum, glass, concrete, resins such as acrylic, and wood. The shape of the cover member 4 is not particularly limited, provided that it is a shape that can at least cover the spacer member 3. For example, it may be a plate-like member whose shape when viewed from above is polygonal (e.g., triangular, rectangular, pentagonal, or hexagonal), or circular (including elliptical). The cover member 4 has a hole 41 for passing the fixing member 5, as described below. Furthermore, the cover member 4 can have a hole 41', as needed, for passing cables and the like of the electrical equipment fixed to the fixed base 1. The holes 41 and 41' can be drilled in advance, or they can be drilled after the cover member 4 is fixed to the fixed base 1, as described below. Furthermore, by providing the cover member 4 with an uneven surface at least, the possibility of an accident such as a worker's slipping when fixing the electrical equipment to the fixing base 1 can be reduced.

[0015] 4. Fixing member 5 The fixing member 5 protrudes substantially vertically from the upper flat surface of the base member 2 and penetrates the cover member 4 to be exposed to the outside. Here, "substantially vertical" refers to an angle at which the fixing member 5 penetrating the cover member 4 can secure electrical equipment. Therefore, this includes not only cases where the angle between the flat surface 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 can secure electrical equipment using the fixing member 5. The fixing member 5 is a member for fixing electrical equipment to the fixed base 1, as described below. Specific examples of such members include screw fasteners such as bolts, and members for pin fastening. The material of such fixing member 5 can be selected appropriately as long as it can support the electrical equipment installed on the fixed base 1 without movement. Examples of such materials include metals such as iron, steel, and aluminum, glass, concrete, and resins such as acrylic.

[0016] 5. Specific Example 1 of Fixed Base 1 FIG. 1 shows a specific example 1 of a fixed base 1. The fixed base 1 in FIG. 1 has two spacer members 3, which are H-shaped steel beams, installed parallel to one another on the top surface of a concrete base member 2, which has flat upper and lower surfaces. The spacer members 3 are fixed to the base member 2 with fasteners 31 (bolts in FIG. 1). A fixing member 5 (bolt in FIG. 1), which is composed of a shaft 51 and a head 52, is embedded in the base member 2 with the head 52 facing downward. The shaft 51 of the fixing member 5 extends from the upper flat surface of the base member 2 in a direction approximately perpendicular to the plane. The base member 2 and spacer members 3 are surrounded by a cover member 4, leaving space around the spacer members 3. Although the cover member 4 surrounds the base member 2 and the spacer members 3 together in FIG. 1, the cover member 4 may surround only the spacer members 3. In this case, it is preferable that a sufficient space be secured between the cover member 4 and the spacer member 3 so that cables such as electric wires of the electrical equipment fixed to the fixed base 1 can be passed through, as will be described later. More preferably, as described above, it is more preferable that the cover member 4 surrounds the spacer member 3 together with the base member 2. By doing so, it is possible to reduce the irregularities of the fixed base 1, further increase the overall strength of the fixed base 1, and prevent accidents such as workers tripping during installation work.

[0017] The cover member 4 in FIG. 1 is a rectangular box-shaped member made by welding checkered steel plates together. It is installed over the base member 2 and the spacer member 3. The cover member 4 is secured to the side of the base member 2 with fasteners 42 (bolts in FIG. 1). Note that the fasteners 42 are not used when the cover member 4 does not need to be secured. The fixing member 5 protrudes outward from a hole 41 drilled in the cover member 4. A nut 53 is fastened to the shaft 51 of the fixing member 5 at the point where the inner surface of the cover member 4 and the shaft 51 of the fixing member 5 meet. The provision of the nut 53 improves the strength of the cover member 4 near the hole 41, thereby improving durability against the weight of electrical equipment when it is secured to the fixing base 1. A hook may be provided on the top surface of the fixing base 1 to facilitate movement of the fixing base 1 using a rope or the like. Specifically, a hole may be drilled through the spacer member 3 and the cover member 4, and the hook may be fastened with a bolt (not shown).

[0018] 6. Specific Example 2 of Fixed Base 1 A further specific example of the fixed base 1 is shown in FIG. 5. In FIG. 5, parts with the same numbers as those in FIG. 1 are the same as those in FIG. 1 unless otherwise specified. In the example shown in FIG. 5, the concrete base members 2 have a length when viewed from above, and at least two (three in FIG. 5) are arranged in parallel. The spacer members 3 are made of steel, have a length when viewed from above (H-beams in FIG. 5), and are installed so as to span the base members 2 in a direction perpendicular to their longitudinal direction (two in FIG. 5). This configuration reduces the mass of the fixed base 1 and further reduces the burden on the worker when installing the fixed base 1. Although three base members 2 are installed in parallel in FIG. 5, these base members 2 do not necessarily need to be installed parallel, and their positional relationship can be adjusted as needed depending on the installation location, etc. Furthermore, although the spacer members 3 are vertically spanned across the base members 2 in FIG. 5, this angle does not necessarily need to be perpendicular, and this angle can be adjusted as needed depending on the installation location, etc.

[0019] 7. Specific Example 3 of Fixed Base 1 FIG. 6 shows a further specific example of the fixing base 1. In FIG. 6, parts that are assigned the same numbers as in FIGS. 1 and 5 are the same as those in FIGS. 1 and 5 unless otherwise specified. In the example shown in FIG. 6, a base member 2 having a groove 21 and a hook 22 is used as the base member 2 for fixing the fixing member 5 (the central base member 2 shown in FIG. 3(C)). The head 52 of the fixing member 5 (a bolt in FIG. 6) is placed in the groove 21 and hooked by the hook 22. By screwing the fixing member 5 to the base member 2 from the opposite side of the head 52 using a nut 54, the hook 22 is sandwiched between the head 52 and the nut 54, and the fixing member 5 can be fixed to the base member 2 at a desired position in the groove 21. By using the base member 2 described above, the position of the fixing member 5 can be adjusted on-site depending on the conditions of the location where the electrical equipment is installed. When adjusting the position of the fixing member 5 on-site, after the position of the fixing member 5 has been determined, holes 41 can be drilled on-site in the cover member 4 at locations corresponding to the positions of the fixing member 5. Also, in FIG. 6, the spacer member 3 is fixed to the base member 2 without the grooves 21 and the hooking portions 22 using the fasteners 31, but the spacer member 3 may also be fixed to the base member 2 that includes the grooves 21 and the hooking portions 22. In this case, for example, the spacer member 3 can be fixed by drilling holes in predetermined locations, hooking the head of the fastener 31 onto the hooking portions 22, and passing the shaft portion through the hole in the spacer member 3 and fastening with a bolt.

[0020] 8. Specific Example 4 of Fixed Base 1 A further specific example of the fixing base 1 is shown in FIG. 7. In FIG. 7, parts that are assigned the same numbers as those in FIGS. 1, 5, and 6 are the same as those in FIGS. 1, 5, and 6 unless otherwise specified. In the example of FIG. 7, instead of the fixing member 5, a hole 23 is drilled in the base member 2. A fixing member fixing portion 24 (a nut in the example of FIG. 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 drilled in the cover member 4 overlap on line α (see FIGS. 7(B) and (C)). In the example of FIG. 7, the fixing member 5 (e.g., a bolt) can be inserted into the hole 23 via the hole 41 on-site and fixed using the fixing member fixing portion 24 (a nut in the case of FIG. 7) (screw fastening in the case of FIG. 7).

[0021] 9. Fixing electrical equipment using the fixing base 1 8 and 9 show a specific example of fixing electrical equipment EE using the fixing base 1 of the present invention. A hole is drilled in the bottom of the housing HO of the electrical equipment EE, and the shaft 51 of the fixing member 5 protruding from the cover member 4 is inserted into the hole and screwed in with a nut 55 (see FIGS. 8 and 9(A)). At the installation location of the electrical equipment EE, for example, the bottom of the housing HO of the electrical equipment EE can be removed, and the bottom can be fixed to the fixing base 1 by screwing in the nut 55, and then the housing HO can be reassembled to fix the electrical equipment EE to the fixing base 1. Further holes 41′, 41′ can be drilled in the fixing base 1, so that the cable CA of the electrical equipment EE can be routed through the inside of the fixing base 1 and further out. Inside the fixing base 1 of the present invention, a space surrounded by the cover member 4 is secured at least around the spacer member 3, and the cable CA can be passed through this space. The cable CA is enclosed by the cover member 4 and can be passed over the base member 2, eliminating the need for burying the cable and minimizing damage caused by animals. When removing the electrical equipment EE, it can be easily removed by reversing the installation steps. The fixing base 1 of the present invention has a simple structure, making it easy to attach and detach electrical equipment.

[0022] Fig. 9(B) shows a configuration in which electrical equipment EE is fixed using the fixing base 1 of Fig. 7. In the example of Fig. 9(B), the bottom of the housing HO is removed as in the case of Fig. 9(A), and the bottom of the housing HO is fixed to the fixing base 1 by screwing a fixing member 5 (a bolt in Fig. 9(B)) to a fixing member fixing portion 24 (a nut in Fig. 9(B)) embedded in the upper part of a hole 23 drilled in the base member 2 via a hole drilled in the bottom of the HO and a hole 41 in the cover member 4. After the bottom of the housing HO is fixed to the fixing base 1, the housing HO is reassembled in the same manner as in the case of Fig. 9(A).

[0023] When multiple pieces of electrical equipment are to be installed on-site (for example, when an EV charger, a power distribution unit, and a transformer are to be installed in the same location), it is possible to fix these pieces of electrical equipment to a single fixed base 1 by increasing the planar area of ​​the fixed base 1 and the number of fixing members 5 used. By fixing multiple pieces of electrical equipment to a fixed base 1 with such a large area, when connecting the individual pieces of electrical equipment with cables, the cables can be connected through the internal space of the same fixed base 1, eliminating the need for burying the cables. It is also possible to prepare a fixed base 1 for each piece of electrical equipment and fix each piece of electrical equipment to a separate fixed base 1. In this case, by placing each fixed base 1 close to each other, it is possible to minimize the frequency with which the cables connecting each piece of electrical equipment are exposed to the outside. Furthermore, a fixed base 1 without any electrical equipment installed can be used in place of a pipe for passing cables, etc. [Industrial Applicability]

[0024] The fixing base of the present invention can be assembled in advance at a factory or the like and then transported to the site for installation. Furthermore, since its structure is not complicated, it is easy to attach and detach electrical equipment. This significantly reduces the amount of work required at the site where the electrical equipment is installed, and can make a significant contribution to the spread of industries that require electrical equipment, such as EVs.
