Description

[Technical Field]

[0001] The present invention relates to a wire theft prevention fence. [Background technology]

[0002] Ground-mounted solar power plants are being installed for the purposes of environmental conservation activities and effective land utilization. In many ground-mounted solar power plants, the solar power generation system that generates electricity is located away from the distribution board, so the solar power generation system and the distribution board are connected by copper wires buried underground. The distribution board is stored in a cabinet attached to a utility pole. In recent years, there have been cases of wire theft, where underground electric wires have been pulled out and stolen.

[0003] There are known guard fences that enclose an object with barbed wire or galvanized iron to prevent theft of electric wires. For example, as disclosed in Patent Document 1, a guard fence that encloses the perimeter of a building as a crime prevention measure is known. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2017-160630 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, since utility poles equipped with cabinets are often already installed on the ground, it is difficult to install a conventional protective fence that surrounds the object later.Furthermore, it is desirable that the protective fence can be attached to utility poles equipped with cabinets of various shapes.

[0006] To provide an electric wire theft prevention fence which can be easily attached later, has a simple structure, and can suitably prevent the theft of electric wires. [Means for solving the problem]

[0007] The wire theft prevention fence of the embodiment is attached to a utility pole equipped with a cabinet. The wire theft prevention fence of the embodiment includes a plurality of unit reinforcing bars, each of which is made of metal rods assembled in a lattice pattern. The combination of the unit reinforcing bars forms a fence section that surrounds the periphery of the utility pole. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide an electric wire theft prevention fence that can be easily installed later, has a simple structure, and is capable of effectively preventing theft of electric wires. [Brief explanation of the drawings]

[0012] [Configuration of 200 utility poles] A utility pole 200 to which an electric wire theft prevention fence 100 according to an embodiment is attached will be described with reference to Figure 1. However, the utility pole 200 does not need to have all of the components described below, and some components may be omitted as appropriate.

[0013] FIG. 1 is a perspective view showing a utility pole 200 to which an electric wire theft prevention fence 100 is attached. 1, the utility pole 200 includes a cabinet 210. The utility pole 200 is grounded to the ground and extends upward.

[0014] The cabinet 210 includes a distribution board cabinet 211, an electric meter cabinet 212, and a CT board cabinet 213. The distribution board cabinet 211 houses a distribution board (not shown). The electric meter cabinet 212 houses an electric meter (not shown). The CT board cabinet 213 houses a CT board (not shown). The distribution board cabinet 211 is attached to the rear side of the utility pole 200. The electric meter cabinet 212 is attached to the front side of the utility pole 200. The CT board cabinet 213 is attached to the front side of the utility pole 200. The electric meter cabinet 212 is attached above the distribution board cabinet 211. The CT board cabinet 213 is attached above the electric meter cabinet 212.

[0015] In this embodiment, the distribution board cabinet 211 has a substantially rectangular shape when viewed from the rear, a vertical length of 730 mm, a horizontal length of 410 mm, and a lower end located 600 mm from the ground. In this embodiment, the electric meter cabinet 212 has a substantially rectangular shape when viewed from the front, a vertical length of 650 mm, a horizontal length of 300 mm, and a lower end located 270 mm from the upper end of the distribution board cabinet 211. In this embodiment, the CT board cabinet 213 has a substantially rectangular shape when viewed from the front, a vertical length of 460 mm, a horizontal length of 470 mm, and a lower end located 75 mm from the upper end of the CT board cabinet.

[0016] The utility pole 200 on which the electric wire theft prevention fence 100 is attached is not limited to the above, and for example, the distribution panel cabinet 211 may be attached to the front side, the left side, or higher than the CT panel cabinet, and the shape of the distribution panel cabinet 211 may be different from that in this embodiment. The positions at which the electric meter cabinet 212 and the CT panel cabinet 213 are attached to the utility pole and the shapes of the electric meter cabinet 212 and the CT panel cabinet 213 may also be different from those in this embodiment.

[0017] [Configuration of the electric wire theft prevention fence 100] 2 to 12, the electric wire theft prevention fence 100 of this embodiment will be described. First, the overall configuration of the electric wire theft prevention fence 100 will be described. However, the electric wire theft prevention fence 100 does not need to have all of the components described below, and some components may be omitted as appropriate.

[0018] 2 is a perspective view showing the electric wire theft prevention fence 100. The electric wire theft prevention fence 100 is an invention that can prevent theft of electric wires in a distribution board attached to an electric pole by surrounding the outer periphery of the pole with multiple unit reinforcing bars 10. The electric wire theft prevention fence 100 comprises a unit reinforcing bar 10, an electric pole fixing band 11, and a pole guide 12. The electric wire theft prevention fence 100 is attached to an electric pole 200 equipped with a cabinet 210.

[0019] As shown in FIG. 2, the unit reinforcing bar 10 is formed by assembling metal rods 10a in a lattice pattern. The unit reinforcing bar 10 is a lattice-like combination of vertical bars 10b extending in the up-down direction and stirrups 10c extending in the width and depth directions. The vertical bars 10b and the stirrups 10c are fixed by welding. The unit reinforcing bar 10 is coated with hot-dip galvanization. The vertical bars 10b and the stirrups 10c are positioned such that the vertical bars 10b are on the inside and the stirrups 10c are on the outside. The inside is the side of the utility pole 200 when the electric wire theft prevention fence 100 is installed around the utility pole 200, and the outside is the side opposite the utility pole 200 when the electric wire theft prevention fence 100 is installed around the utility pole 200.

[0020] In this embodiment, reinforcing bars with a diameter of 10 mm are used for the vertical reinforcement bars 10b and the stirrups 10c. The largest gap between the openings in the lattice of the unit reinforcing bars 10 is 127 mm or more and 156 mm or less. The shape of the lattice formed by the vertical reinforcement bars 10b and the stirrups 10c is a square with a side length of 100 mm. Note that the unit reinforcing bars 10 are not limited to the above. For example, the shape of the lattice formed by the vertical reinforcement bars 10b and the stirrups 10c may be a square with a side length of 100 mm or less, or the lattice shape may be triangular or round, or reinforcing bars with a radius of 10 mm or more may be used. It is preferable that the lattice of the unit reinforcing bars 10 be large enough to prevent the insertion of tools for cutting electric wires, such as cable cutters.

[0021] By combining a plurality of unit reinforcing bars 10, a fence section 1 is formed that surrounds the outer periphery of a utility pole 200, as shown in Fig. 2. In this embodiment, the height of the fence section 1 from the ground is 3000 mm or more.

[0022] In this embodiment, the unit reinforcing bars 10 include a lower main body portion 5, a lower door fence 6, an upper main body portion 7, an upper door fence 8, and a top fence 9. In this embodiment, the outer periphery of the utility pole 200 is surrounded by combining the lower main body portion 5, the lower door fence 6, the upper main body portion 7, the upper door fence 8, and the top fence 9. However, the electric wire theft prevention fence 100 is not limited to the above, and may, for example, have only one door or three or more doors, or may have a middle fence portion that can be connected to the lower fence portion 3 and the upper fence portion 4. In other words, it is sufficient to combine multiple unit reinforcing bars 10 to surround the outer periphery of the utility pole 200.

[0023] The fence section 1 has a lower fence section (first fence section) 3 and an upper fence section (second fence section) 4. The lower fence section 3 is formed by combining multiple unit reinforcing bars 10 and surrounds the outer periphery of the utility pole 200. The upper fence section 4 is formed by combining multiple unit reinforcing bars 10 and surrounds the outer periphery of the utility pole 200. The lower fence section 3 and upper fence section 4 can be connected in the vertical direction.

The left rear fence 55 has a hook bolt 5a. The right rear fence 56 extends leftward from the rear end of the right fence 54. The right rear fence 56 has a door support rebar 5b. The right end of the left rear fence 55 and the left end of the right rear fence 56 are not connected.

[0026] The front fence 51 is rectangular, measuring 1660 mm ± 10 mm in the vertical direction and 800 mm ± 10 mm in the horizontal direction. The left fence 53 is rectangular, measuring 1660 mm ± 10 mm in the vertical direction and 700 mm ± 10 mm in the depth direction. The right fence 54 is rectangular, measuring 1660 mm ± 10 mm in the vertical direction and 700 mm ± 10 mm in the depth direction. The left rear fence 55 is rectangular, measuring 1660 mm ± 10 mm in the vertical direction and 100 mm ± 10 mm in the horizontal direction. The right rear fence 56 is rectangular, measuring 1660 mm ± 10 mm in the vertical direction and 100 mm ± 10 mm in the horizontal direction.

[0027] The hook bolt 5a extends rearward from the left rear fence 55 and has a ring-shaped portion through which a hook 6a, described below, can be passed. The hook bolt 5a is fixed so that the hole in the ring-shaped portion faces vertically. The hook bolt 5a is fixed by welding to the left rear fence 55. Two hook bolts 5a are provided, spaced apart in the vertical direction. The lower hook bolt 5a is located 360 mm above the bottom edge of the left rear fence 55. The upper hook bolt 5a is located 300 mm below the top edge of the left rear fence 55.

[0028] The door support rebar 5b is a rod-shaped member extending rearward from the right rear fence 56. The door support rebar 5b limits the movement of the lower door fence 6 when it is closed. The door support rebar 5b is welded and fixed to the right rear fence 56. Two door support rebars 5b are provided, spaced apart in the vertical direction. The lower door support rebar 5b is provided 360 mm above the bottom end of the right rear fence 56. The upper door support rebar 5b is provided 300 mm below the top end of the right rear fence.

[0029] Fig. 6 is a perspective view showing the upper and lower connecting guide 5c, and Fig. 7 is a perspective view showing the upper fence part 4 being attached to the lower fence part 3 by the upper and lower connecting guide 5c. The upper and lower connecting guides 5c are components that allow the upper fence section 4 to be assembled to the lower fence section 3 by fitting the upper fence section 4 into them. As shown in FIG. 6, the upper and lower connecting guides 5c are composed of two reinforcing bars extending in the vertical direction, and the two reinforcing bars are installed from above the lower fence section 3 so as to sandwich two stirrups 10c. The reinforcing bars of the upper and lower connecting guides 5c and the stirrups 10c of the lower fence section 3 are fixed by welding. As shown in FIG. 7, the upper fence section 4 can be attached to the lower fence section 3 by fitting the stirrups 10c at the lower end of the upper fence section 4 between the two reinforcing bars of the upper and lower connecting guides 5c. Two upper and lower connecting guides 5c are provided on the left fence 53 and two on the right fence 54. The upper and lower connecting guides 5c use reinforcing bars with a diameter of 10 mm and a length of 200 mm.

[0030] In this embodiment, reinforcing bars with a diameter of 13 mm are used for the stirrups 10c at the upper end of the lower fence section 3. The stirrups 10c at the upper end of the lower fence section 3 are thicker than the second stirrups 10c from the top of the lower fence section 3 and the stirrups 10c at the lower end of the upper fence section 4. This widens the gap between the two reinforcing bars of the upper and lower connecting guides 5c, making it easier to fit the upper fence section 4 into the upper and lower connecting guides 5c.
