DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] A preferred embodiment 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 each drawing.

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

[0010] 1. Foundation member 2 The base member 2 is a member having at least a flat surface on the upper side. The base member 2 is a base for supporting the spacer member 3 described later, and is also a base for supporting the cable of the electrical equipment fixed to the fixing base 1 so that it does not come into direct contact with the ground. The base member 2 is also a base member for fixing the cover member 4 described later as necessary. The shape of the base member 2 can be adjusted appropriately according to the topography of the location where the electrical equipment is installed. For example, as shown in Figs. 2(A) to (C), the planar shape of the base member 2 may be rectangular, and the lower side of the base member 2 may be a flat surface if the location where the electrical equipment is installed is flat. If the location where the electrical equipment is installed has an incline, the base member 2 may be inclined in the left-right direction and / or the front-back direction, for example, as shown in Figs. 2(D) to (E). If the installation location has fine irregularities, the lower surface of the base member 2 may be provided with fine irregularities (not shown). The shape of the base member 2 as viewed from the planar direction may also be a polygon such as a triangle, a square including a rectangle, a pentagon, or a hexagon, or a circle including an ellipse. The shape of the base member 2 as viewed from the planar direction may also be a shape having a length in the front-back or left-right direction, for example, a rectangle or an ellipse. The upper side of the base member 2 may have protrusions or irregularities (not shown) on the condition that the upper side has a flat surface large enough to accommodate the spacer member 3, as described below.

[0011] 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 below. Examples of such materials include metal materials such as iron, steel, and aluminum, glass materials, concrete materials, resin materials such as acrylic, and wood, etc. Among these, it is more preferable to use a concrete material, since it is less susceptible to the effects of the environment such as humidity at the installation location and is relatively easy to process.

[0012] The base member 2 used in the present invention may include a groove portion 21 on its upper surface and a hook portion 22 protruding from the vicinity of the upper end of the groove portion 21 toward the center of the groove. FIG. 3 shows an example of the base member 2 including the groove portion 21 and the hook portion 22. As shown in FIG. 3(A) to (C), the groove portion 21 extending in the front-rear direction is provided at the approximate center in the left-right direction of the base member 2. The hook portion 22 protrudes from the vicinity of the upper left and right ends of the groove portion 21 toward the approximate center in the left-right direction of the groove portion 21. The groove portion 21 and the hook portion 22 are used when fixing the fixing member 5 to the base member 2, as described later. The shape of the hook portion 22 as described above 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 described later. The groove portion 21 and the hook portion 22 may be formed by cutting or the like after the base member 2 is manufactured, or a mold for forming the groove portion 21 and the hook portion 22 may be used when molding the base member 2. The shape of the groove 21 as viewed from the planar direction may be a straight line as shown in Fig. 3, or a bent line. The shape of the groove 21 as viewed from the front direction may be a polygon such as a square as shown in Fig. 3, or a semicircular shape. The base member 2 having the groove 21 and the hook portion 22 may be used when fixing the fixing member 5 as described above, or may be used when fixing the spacer member 3 as described later.

[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 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. Further, it may be a rod-shaped member having a length and having 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 (it is 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 appropriately selected on 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. The shape of the cover member 4 is not particularly limited on condition that it is a shape that can cover at least the spacer member 3. For example, it may be a plate-shaped member whose shape when viewed from the planar direction is a polygon such as a triangle, a square, a pentagon, and a hexagon, or a circle including an ellipse. The cover member 4 has a hole 41 for passing the fixing member 5 therethrough, as described later. In addition, the cover member 4 can have a hole 41' for passing cables of the electrical equipment fixed to the fixed base 1, as necessary. The holes 41 and 41' can be opened in advance, or can be opened after the cover member 4 is fixed to the fixed base 1, as described later. Furthermore, by providing at least the surface of the cover member 4 with an uneven surface, 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 is a member that protrudes in a substantially vertical direction 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" means an angle at which the fixing member 5 penetrating the cover member 4 can fix the electrical equipment. Therefore, it includes not only a case 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 an angle other than vertical at which the electrical equipment can be fixed by the fixing member 5. The fixing member 5 is a member for fixing the electrical equipment fixed to the fixing base 1 as described later. Specific examples of such members include, for example, members for screw fastening such as bolts, such as bolts and members for pinning. The material of such fixing member 5 can be appropriately selected on the condition 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.

[0016] 5. Specific Example 1 of Fixed Base 1 FIG. 1 shows a specific embodiment 1 of the fixing base 1. In the fixing base 1 of FIG. 1, two spacer members 3, which are H-shaped steel bars, are installed in parallel 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 FIG. 1). A fixing member 5 (bolts in FIG. 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 downward. The shaft portion 51 of the fixing member 5 extends from the upper flat surface of the base member 2 in a direction approximately perpendicular to the direction of the plane. The base member 2 and the spacer member 3 are surrounded by a cover member 4, and a space is secured around the spacer member 3. In FIG. 1, the cover member 4 surrounds the spacer member 3 together with the base member 2, but the cover member 4 may be used to surround only the spacer member 3. In this case, it is preferable that a space is provided between the cover member 4 and the spacer member 3 so that cables such as electric wires of electrical equipment fixed to the fixed base 1 can be passed through as described below. 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. In this way, the irregularities of the fixed base 1 are reduced, the overall strength of the fixed base 1 is increased, and accidents such as a worker tripping during installation work can be avoided.

[0017] The cover member 4 in FIG. 1 is a box-shaped cover with no bottom, made by welding checkered steel plates having a rectangular planar shape, and is installed so as to cover the base member 2 and the spacer member 3. The cover member 4 is fixed to the side of the base member 2 by fasteners 42 (bolts in FIG. 1). When it is not necessary to fix the cover member 4, the fasteners 42 are not used. The fixing member 5 protrudes outward from a hole 41 formed in the cover member 4. A nut 53 is fastened to the shaft portion 51 so as to be located at the point where the inner surface of the cover member 4 and the shaft portion 51 of the fixing member 5 come into contact with each other. By providing the nut 53 as described above, the strength of the cover member 4 near the hole 41 can be improved, and the durability against the mass of the electrical equipment can be further improved when the electrical equipment is fixed to the fixing base 1. In addition, a hook may be provided on the upper surface of the fixing base 1 to make it easier to move 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 bolted (not shown).

[0018] 6. Specific Example 2 of the Fixed Base 1 A further specific embodiment of the fixed base 1 is shown in FIG. 5. In FIG. 5, the parts with the same numbers as those in FIG. 1 are the same as those in FIG. 1 unless otherwise specified. In the embodiment of FIG. 5, the concrete base member 2 has a shape having a length when viewed from a planar direction, and at least two (three in FIG. 5) are arranged in parallel. The spacer member 3 is made of steel, has a shape having a length when viewed from a planar direction (H-shaped steel in FIG. 5), and is installed so as to span in a direction perpendicular to the length direction of the base member 2 (two in FIG. 5). By adopting such a form, the mass of the fixed base 1 can be made lighter, and the burden on the worker when installing the fixed base 1 can be further reduced. Although the three base members 2 are installed in parallel in FIG. 5, the base members 2 do not necessarily need to be installed in parallel, and the positional relationship between them can be appropriately adjusted depending on the installation location, etc. Furthermore, in FIG. 5, the spacer member 3 spans the base member 2 in a vertical direction, but the angle does not necessarily need to be perpendicular, and the angle can be appropriately adjusted depending on the installation location, etc.

[0019] 7. Specific Example 3 of Fixing Base 1 A further specific embodiment of the fixing base 1 is shown in FIG. 6. In FIG. 6, the parts having the same numbers as those in FIG. 1 and FIG. 5 are the same as those in FIG. 1 and FIG. 5 unless otherwise specified. In the embodiment of FIG. 6, a base member 2 having a groove portion 21 and a hook portion 22 is used as the base member 2 for fixing the fixing member 5 (the base member 2 in the middle shown in FIG. 3(C)). The fixing member 5 (bolt in FIG. 6) has its head 52 placed in the groove portion 21 and hooked by the hook portion 22. The head 52 and the nut 54 are screwed together from the opposite side of the head 52 to sandwich the hook portion 22, and the fixing member 5 can be fixed to the base member 2 at a desired position of the groove portion 21. By using the base member 2 as described above, the position of the fixing member 5 can be appropriately adjusted on-site according to the conditions of the place where the electrical equipment is installed. When the position of the fixing member 5 is adjusted on-site, after the position of the fixing member 5 is determined, a hole 41 can be drilled on-site at a location on the cover member 4 that corresponds to the location of the fixing member 5. In addition, although the spacer member 3 is fixed to the base member 2 without the groove portion 21 and the hook portion 22 by using the fastener 31 in Fig. 6, the spacer member 3 may be fixed to the base member 2 that includes the groove portion 21 and the hook portion 22. In this case, for example, the spacer member 3 can be fixed by drilling a hole at a predetermined location, hooking the head of the fastener 31 onto the hook portion 22, and passing the shaft portion through the hole in the spacer member 3 and bolting it.

[0020] 8. Specific Example 4 of the Fixed Base 1 A further specific embodiment of the fixing base 1 is shown in FIG. 7. In FIG. 7, the parts having the same numbers as those in FIG. 1, 5, and 6 are the same as those in FIG. 1, 5, and 6 unless otherwise specified. In the embodiment of FIG. 7, instead of the fixing member 5, a hole 23 is formed in the base member 2. A fixing member fixing part 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 formed in the cover member 4 overlap on the line α (see FIG. 7(B) and (C)). In the embodiment of FIG. 7, the fixing member 5 (e.g., a bolt) can be inserted into the hole 23 through the hole 41 at the site and fixed using the fixing member fixing part 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 the electrical equipment EE using the fixing base 1 of the present invention. A hole is provided 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 with a nut 55 (see FIGS. 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 is removed, and the bottom is fixed to the fixing base 1 by screwing with the nut 55, and then the housing HO is reassembled to fix the electrical equipment EE to the fixing base 1. In addition, holes 41', 41' are further provided in the fixing base 1, so that the cable CA of the electrical equipment EE can be further sent out to the outside through the inside of the fixing base 1. 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 the space. The cable CA is surrounded 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, etc. When removing the electrical equipment EE, it can be easily removed by reversing the steps taken during installation. The fixing base 1 of the present invention has an uncomplicated structure, making it easy to attach and detach electrical equipment.

[0022] Fig. 9(B) shows a form in which the 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 in the same manner as in Fig. 9(A), and the bottom of the housing HO is fixed to the fixing base 1 by screwing the fixing member 5 (bolt in Fig. 9(B)) to the fixing member fixing portion 24 (nut in Fig. 9(B)) embedded in the upper part of the hole 23 opened in the base member 2 through the hole opened in the bottom of the HO and the 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 Fig. 9(A).

[0023] When multiple electrical equipment are installed on-site (for example, an EV charger, a power distributor, and a transformer are installed in the same location), the multiple electrical equipment can be fixed to one fixed base 1 by increasing the area of ​​the fixed base 1 in the planar direction and increasing the number of fixing members 5 used. By fixing multiple electrical equipment to a fixed base 1 with such a large area, when connecting individual 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. Also, a fixed base 1 can be prepared for each individual piece of electrical equipment, and each piece of electrical equipment can be fixed to each fixed base 1. In this case, by placing each fixed base 1 close to each other, the frequency with which the cables connecting each piece of electrical equipment are exposed to the outside can be reduced as much as possible. Also, the fixed base 1 without electrical equipment installed can be used as a substitute for piping 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, electrical equipment can be easily attached and detached. This significantly reduces the amount of work required at the site to install the electrical equipment, and can greatly contribute to the spread of industries that require electrical equipment, such as EVs.
