Description

[Technical Field]

[0001] This invention relates to a security device for distribution boards, and in particular to a distribution board storage device that covers the outer periphery of the distribution board with a shielding body and combines a mesh structure with specified dimensions, door placement, gap control, and multiple locking mechanisms to physically and psychologically deter theft and unauthorized access. [Background technology]

[0002] In recent years, distribution boards installed in power facilities, solar power generation systems, and other equipment have been increasingly subject to theft and unauthorized operation, targeting the copper wires and devices inside. Conventional methods of protection include physical protection using covers or enclosures to cover the distribution board, or systems that detect and report broken copper wires. However, most conventional technologies rely on simple enclosure structures or electrical detection means, which pose a problem: if an intruder breaches one of the defenses, they can easily gain access to the interior. Furthermore, the strength and ease of installation of protective structures are sometimes insufficient depending on the topography and environment of the construction site.

[0003] In view of the above, various proposals have been made to prevent theft of distribution boards and electric wires. For example, Patent Document 1 (JP 2024-174675 A) discloses a cable theft prevention device that detects a break in a detection conductive wire provided in a wiring or cable and activates an alarm device or monitoring device. Furthermore, Patent Document 2 (JP Patent No. 7613784 A) proposes a configuration that utilizes a break in a theft prediction detection conductive wire provided along a cable and activates a warning light or alarm device based on a break signal.

[0004] Furthermore, Patent Document 3 (Japanese Patent No. 7575650) discloses a wiring theft prevention device and its installation method that prevents theft by covering the piping with a case body and lifting the piping above the ground surface with a lifting mechanism.In addition, Patent Document 4 (Utility Model Registration No. 3250508) discloses a power transmission cable theft prevention box that provides supports and panels to surround the lead-in utility poles in a solar power generation facility, making the power transmission cables and current transformers invisible from the outside and thus deterring theft.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-174675 [Patent Document 2] Patent No. 7613784 [Patent Document 3] Patent No. 7575650 [Patent Document 4] Utility Model Registration No. 3250508 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the technologies described in Patent Documents 1 to 4 above still have the following problems. Specifically, the cable anti-theft devices disclosed in Patent Documents 1 and 2 issue an alarm based on the detection of a break in the conductive wire, and do not have a structure that physically prevents intruders from inserting their hands or trying to pry open the door. Furthermore, the anti-theft technologies using enclosure structures described in Patent Documents 3 and 4 simply cover the equipment to prevent it from being seen, and do not have any active deterrent measures such as specifying mesh dimensions or gap dimensions to prevent the intrusion of third parties' hands or tools, or providing multiple locking mechanisms or dummy locks for disruption.

[0007] As such, all of the conventional technologies have issues such as not having a structure that prevents unauthorized entry by strictly specifying the mesh opening dimensions or the distance between the door and the distribution board, not taking measures such as leaving the bottom end uncut or burrs to psychologically discourage trespassers, and not having any ingenuity to make it difficult to operate unauthorized tools by combining a multi-layered locking structure, such as a cylindrical locking mechanism, padlock, or a structure that prevents visibility using stuffing.

[0008] To solve the above problems, this device provides a shielded frame surrounding the distribution board with mesh and door structures of specified dimensions, controlling gaps on the top, bottom, left, and right to prevent the intrusion of hands and tools, while also utilizing the psychological deterrent effect of cutting off the bottom edge. The door is also equipped with multiple locking mechanisms, with dummy locks making unauthorized unlocking difficult, and padlocks that penetrate the cylindrical members and hidden plugs that prevent external tool operation and identification of screw shapes. By combining these physical and psychological deterrent measures, the goal is to provide a distribution board storage device that provides high security in a variety of installation environments. [Means for solving the problem]

[0009] In order to solve the above problems, the distribution board storage device according to the present invention has the following configuration. A distribution board storage device for protecting a distribution board attached to a support from the outside comprises a shielding body, a mesh constituting the shielding body, a door formed in part of the mesh, and a locking mechanism for locking the door, the door being positioned opposite the distribution board to allow inspection and maintenance work on the distribution board.

[0010] In addition, the distance between the door and the distribution board when viewed from the side is set to between 0 cm and 5 cm, and the structure is such that a third party cannot insert their hand into that distance.

[0011] The mesh has diamond-shaped openings, the height of which is 2 cm or less and the width of which is 4 cm or less, so that a third party cannot insert their hands into the openings.

[0012] The mesh at the lower end of the shield body is left uncut (unpolished) where it comes into contact with the ground, and sharp burrs measuring 1 mm to 3 mm in height and at a 90-degree angle are intentionally left behind, which creates a psychological effect of making people who come into contact with it feel uncomfortable and discouraging them from entering.

[0013] The distance between the outer periphery of the distribution board facing the opening of the door and the open end of the mesh is set to 0 to 7 cm in the vertical direction and 0 to 10 cm in the horizontal direction in a plan view.

[0014] In addition to the locking mechanism, the door is equipped with one or more dummy locking mechanisms with a similar appearance, making it difficult for a third party to unlock it illegally.

[0015] The locking mechanism is made up of a cylindrical member with a screw inside, and a padlock that passes through the cylindrical member prevents the entry of a wrench or the like, thereby preventing unauthorized operation of the screw.

[0016] Furthermore, the length of the cylindrical member is set to be between 5 cm and 15 cm, and the structure is such that tools such as screwdrivers cannot easily reach the internal screws.

[0017] In addition, a filler is placed between the ring part of the padlock and the screw, making the shape of the screw invisible from the outside.

[0018] The upper surface of the shield body is covered by an upper cover having through holes formed around the support posts to maintain a predetermined distance, and this distance is specified to be 0 to 8 cm. [Effects of the Invention]

[0019] According to this invention, by constructing the shielding body from mesh and placing the door opposite the distribution board, it is possible to prevent unauthorized intrusion from outside while facilitating inspection and maintenance work.

[0020] By specifying the distance between the door and the distribution board as 0 to 5 cm, third parties are prevented from reaching inside, ensuring safety.

[0021] By specifying the mesh opening dimensions to be no more than 2 cm in height and 4 cm in width, hands can be reliably prevented from entering.

[0022] The bottom end is cut off and a sharp burr with a height of 1 to 3 mm and an angle of 90 degrees is left, which causes discomfort to those who come into contact with it and acts as a psychological deterrent.

[0023] By limiting the distance between the door opening and the outer periphery of the distribution board to 0-7 cm above and below, and 0-10 cm below and to the left and right, it is possible to prevent the insertion of unauthorized tools or entry through gaps.

[0024] By providing a dummy lock mechanism in addition to the locking mechanism on the door, it is possible to confuse intruders and make it difficult to unlock the door illegally.

[0025] The padlock penetrates the cylindrical part of the locking mechanism, preventing wrenches and screwdrivers from getting in. Furthermore, by setting the length of the cylindrical part to 5-15cm, it becomes difficult for tools to reach the screws, improving security.

[0026] By placing a filler between the ring part of the padlock and the screw, the shape of the screw cannot be seen from the outside, making it even more difficult to tamper with it using tools.

[0027] In addition, by placing the top cover at intervals of 0 to 8 cm around the support, it is possible to reliably prevent unauthorized entry from above while ensuring construction errors and breathability.

[0028] As described above, by combining dimensional specifications, cutting processing, multiple locking mechanisms, and a visually obscuring structure, this device increases the physical and psychological deterrent effect of intrusion, and can provide a high level of security even in outdoor installation environments.

[Figure 8] 1 is a top view of the distribution board storage device of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0030] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to these embodiments, and design changes and alternative means for each component are possible. As shown in Figure 1, the distribution board storage device 1 of the present invention is intended to protect a distribution board 4 attached to a support 3 from the outside. The distribution board storage device 1 includes a shielding body 2 made of mesh 21, a door 6 formed in a part of the shielding body 2, and a locking mechanism 61 for locking the door 6.

[0031] As shown in Figure 2, door 6 is positioned opposite distribution board 4. This allows for easy access to distribution board 4 by opening door 6, enabling reliable inspection and maintenance work. Also, as shown in Figure 2, the distance d between door 6 and distribution board 4 is specified as 0 to 5 cm. While allowing for construction error, this dimension is smaller than the thickness of an adult's finger (approximately 2 cm for the index finger and approximately 2.5 cm for the thumb) and the thickness of the palm of the hand (approximately 4 to 5 cm), making it physically impossible for a third party to reach inside by inserting their finger or hand. Therefore, this dimension setting reliably prevents unauthorized interference from outside while maintaining the proximity necessary for inspection and maintenance.

[0032] As shown in Figure 3, the mesh 21 at the bottom end of the shield body 2 is left uncut (unpolished). In addition, sharp burrs 1 to 3 mm high and at a 90-degree angle are intentionally left behind to stimulate a painful sensation the moment they are touched, giving the person who comes into contact with it a strong sense of discomfort and danger. This structure not only psychologically discourages intrusion, but also makes it difficult for those around to "carelessly touch" it.

[0033] As shown in Figure 3, the diamond-shaped openings in the mesh 21 are regulated to a height a of 2 cm or less and a width b of 4 cm or less. These dimensions are significantly smaller than the diameter of an adult's wrist (approximately 5-6 cm) or forearm (approximately 7-8 cm), making it impossible for the entire upper limb to enter. Therefore, the mesh dimensions are rationally set based on the anatomical dimensions of the human body, ensuring high security.

[0034] As shown in Figure 4, the distance c between the opening 62 of the door 6 and the outer periphery of the distribution board 4 is specified as 0 to 7 cm in the vertical direction and 0 to 10 cm in the horizontal direction. This dimension range is narrow enough compared to the shoulder width (average approximately 40 cm), chest circumference (over 80 cm), and head width (approximately 15 cm) of an adult, making it impossible for a person to enter through this gap. Furthermore, compared to the tip of a wire cutter or other illegal tool, this dimension lacks the clearance necessary to effectively insert the tool. Therefore, this dimension specification physically prevents the insertion of illegal tools and the entry of people, thereby enhancing the effectiveness of intrusion prevention.

[0035] As shown in Figure 5, in addition to the locking mechanism 61, the door 6 is equipped with multiple dummy locking mechanisms 62 that look similar. This prevents a third party attempting to unlock the door illegally from immediately identifying the actual locking position, significantly increasing the time required to unlock the door. As a result, the risk of continued crime increases, dramatically improving the deterrent effect.

[0036] 6 and 7, the locking mechanism 61 is made up of a cylindrical member with a screw 63 inside. This cylindrical member is penetrated by a padlock 65, and the presence of the padlock 65 prevents tools such as wrenches from entering the cylindrical member. This prevents unauthorized manipulation of the screw 63. The number of corners of the screw can also be changed randomly.

[0037] The length L of the cylindrical member is set to 5 to 15 cm. This range prevents a typical screwdriver or wrench from reaching the internal screw 63 in a linear fashion. Even if a tool is inserted, the padlock 65 physically interferes, making tampering virtually impossible. Furthermore, the padlock 66 placed between the padlock 65 and the screw 63 completely obscures the shape of the screw head from the outside, making it difficult to select a tampering tool. The padlock 66 placed between the padlock 65 and the screw 63 not only prevents the screw shape from being seen, but also has the secondary effect of creating play at the tip of the tool even if it is inserted, significantly reducing the accuracy of tampering. The padlock 66 is formed, for example, from a metal spacer, a wear-resistant resin block, a rubber-based elastomer, or a filler, and can be shaped in various ways, such as a ring, sleeve, disk, or hollow filler. All of these create play between the tip of the tool and the screw head when the tool is inserted, reducing operation accuracy. Furthermore, the material and shape of the filler 66 are not limited to these, and any structure that makes the screw shape invisible from the outside and makes it difficult to operate an unauthorized tool can be widely adopted.

[0038] As shown in Figure 8, the top surface of the shielding body 2 is covered by a top cover 22. This top cover 22 has through-holes around the support posts 3, maintaining a spacing e of 0 to 8 cm. This structure prevents unauthorized intrusion from above while ensuring construction errors and heat dissipation. The shape of the through-holes can be freely designed, and may be rectangular, polygonal, or circular. Furthermore, the spacing e (0 to 8 cm) formed in the top cover 22 can accommodate variations in support post diameter and uneven ground conditions at the construction site. It also ensures heat dissipation from the distribution board 4 and has a drainage effect to prevent rainwater from accumulating. Furthermore, by setting the spacing e to 8 cm or less, it is physically impossible for a person's entire body to pass through the gap. In other words, the dimension of 0 to 8 cm is significantly smaller than the shoulder width (average approximately 40 cm), chest circumference (over 80 cm), and head width (approximately 15 cm) of an adult, so it is reliably prevented from invading from above through the gap.

[0039] As described above, the distribution board storage device 1 of this embodiment shown in Figures 1 to 8 physically and psychologically deters intrusion by combining specified mesh dimensions and gap dimensions, raw cut processing and residual burrs to provide psychological deterrence, multiple locking mechanisms and dummy locks, a combination of cylindrical members and padlocks, and a packing material to prevent visibility, thereby demonstrating high security in outdoor installation environments. [Industrial Applicability]

[0040] The distribution board storage device of the present invention is constructed by combining multiple means to physically and psychologically deter intrusions in order to protect the distribution board from outside. Therefore, it is widely applicable to the protection of equipment installed outdoors that is at risk of theft or unauthorized operation by third parties, such as power equipment, communication equipment, solar power generation systems, factory facilities, and public infrastructure equipment.

[0041] In particular, by specifying the mesh dimensions of the shielding body and the spacing between the door and distribution board based on the size of the human body, it is possible to physically prevent the intrusion of a person's fingers, arms, or entire body, making it effective in industrial fields that require high levels of security. Furthermore, by introducing the psychological deterrent effect of the cut-off processing, a disturbance structure with a dummy lock mechanism, and a multiple defense structure with a padlock and cylindrical members, it demonstrates significantly higher theft prevention performance than conventional methods.

[0042] The spacing of the top cover and the structure of the shield body can flexibly accommodate differences in post diameter at each site and construction conditions on uneven ground, making it highly versatile for power companies and facility construction contractors.In addition, the structure has excellent wind and weather resistance, so it can be used stably even in harsh natural environments such as strong winds, rain, and direct sunlight.

[0043] For these reasons, the distribution board storage device of the present invention has extremely high industrial value, including for the maintenance and management of power and communication infrastructure, crime prevention for renewable energy facilities, and ensuring security for public facilities.
