Description

[Technical field]

[0001] The present invention relates to an anti-theft mechanism for copper cables to be installed on a specified site where solar power generation equipment using copper cables is installed, or a demonstration device using the anti-theft mechanism for copper cables. [Background technology]

[0002] The trends in copper cable theft so far have been as follows: 1) Decide on a target using Google Maps etc. 2) Conduct a preliminary inspection. Before committing a crime, conduct a preliminary inspection to check the following points: Whether or not there is a security system. Is there a lot of foot traffic? Whether the power plant is well looked after by people or not. Is the cable easy to steal? Check vehicle entry / exit routes. Additionally, the following methods have also been reported: Investigate over several days and find times when no one is around. We deliberately break the fence to see how quickly they respond and decide whether to repair it or not. 3) After conducting this reconnaissance, it is believed that multiple perpetrators, including perpetrator A and perpetrator B, will break into solar system S as shown in Figure 8 and commit the crime.

[0003] Incidentally, a conventional anti-theft structure for a cable is known from Japanese Patent No. 5855309 (see Patent Document 1). This prior art is an anti-theft structure for a cable comprising a trough body, a trough lid that covers the upper part of the trough body and is fixed to the trough body, a cable arranged inside the trough body, a cable pressing member that presses the cable, and a pressing force applying member that applies a pressing force to the cable pressing member, wherein the cable pressing member is disposed between the cable and the trough lid, and the cable pressing member is an elastic member that contacts the back surface of the trough lid and the cable, and the trough lid is pressed by the pressing force applying member, thereby pressing the cable pressing member against the cable via the trough lid.

[0004] Although hard or soft cross-linked (chemically cross-linked or electron beam cross-linked) polyethylene resin foam is used as the elastic member, the reality is that this does not provide sufficient cable holding or binding power to prevent theft. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 5855309 Summary of the Invention [Problem to be solved by the invention]

[0013] The copper cable theft prevention mechanism of the present invention is characterized in that it has a pair of retaining frames which clamp the copper wire cable from both sides, and fastening means consisting of bolts and nuts are attached to both sides of the retaining frames, and an elastic sheet to prevent displacement is interposed between the retaining frames and the copper wire cable, and the retaining frames are formed with a number of protrusions which engage with the elastic sheet, so that the retaining frames and the copper wire cable are more strongly prevented from being displaced via the elastic sheet.

[0014] The copper cable theft prevention mechanism of the present invention is also characterized in that the retaining frame is fixed in an appropriate position at the copper wire cable installation position within various facilities, thereby preventing the copper wire cable from being removed. EXAMPLES

[0015] FIG. 1 is a schematic cross-sectional view showing one embodiment of the copper cable anti-theft mechanism of the present invention. In FIG. 1, the copper cable theft prevention mechanism of the present invention has a pair of retaining frames 12a, 12b that clamp the copper wire cable 11 from both sides, and fastening means consisting of bolts 13 and nuts 14 are attached to both sides of the retaining frames 12a, 12b. An elastic sheet 15 to prevent displacement is interposed between the retaining frames 12a, 12b and the copper wire cable 11. Furthermore, the retaining frames 12a, 12b are formed with a number of protrusions 16 that engage with the elastic sheet 15 as shown in FIG. 4. Therefore, the retaining frames 12a, 12b and the copper wire cable 11 are formed so as to be more strongly prevented from being displaced via the elastic sheet 15. Needless to say, the holding frames 12a and 12b can be made of metal, rigid resin, or other appropriate materials. Moreover, it goes without saying that the fastening means consisting of the bolts 13 and nuts 14 attached to the holding frames 12a, 12b may be attached not only to both sides of the holding frames 12a, 12b but also to only one side.

[0016] Figure 2 shows a copper wire cable 11 stored in a bellows-shaped protective cover 21 and clamped on both sides by a pair of arc-shaped holders 22a, 22b, where Figure 2a) shows a conventional copper cable theft prevention mechanism 10, and Figure 2b) shows the copper cable theft prevention mechanism 20 of the present invention in which holding frames 12a, 12b are attached to the gaps provided between the bellows-shaped protective cover 21.

[0017] Between the bellows-like protective covers 21, the copper cable 11 is engaged with the holding frames 22a, 22b, and is firmly fixed in place to prevent theft. Although a bellows-shaped protective cover has been exemplified as the protective cover 21, a cover that does not have a bellows-shaped structure may also be used.

[0018] FIG. 3 shows the anti-theft mechanism for copper cables of the present invention, in which a) shows the holding frame when there is one copper cable 11, b) shows the holding frame when there are two copper cables 11, c) shows the holding frame when there are three copper cables 11, and d) shows the holding frame when there are more than two copper cables 11.

[0019] Next, Figure 4a) shows the details of the method of assembling the copper cable anti-theft mechanism 20. A pair of holding frames 12a, 12b that clamp the copper wire cable 11 from both sides have multiple protrusions 16 formed on the recessed surface 12c that engage with the elastic sheet 15, and these protrusions 16 engage with the elastic sheet 15 to more firmly fasten the holding frames 12a, 12b and the copper wire cable 11 via the elastic sheet 15. In addition, any suitable device can be used in place of the above-mentioned bolts 13 and nuts 14. As shown in Figure 4b), a hinge 17 made of flexible metal (spring metal) or the like can be provided on one side, and the other side can be fixed with bolts 13 and nuts 14. It is of course also possible to use any suitable fastening means in place of bolts 13 and nuts 14. Also, as shown in FIG. 4c), instead of engaging the retaining frames 12a, 12b between the bellows-shaped protective covers 21, it is also possible to firmly attach the retaining frames 12a, 12b at predetermined positions by driving stakes 18 of, for example, about 30 cm to 60 cm into the retaining frames 12a, 12b.

[0020] FIG. 5 is a schematic perspective view showing the copper cable anti-theft mechanism 20 when assembled, in which multiple protrusions 16 formed on the surfaces of the recesses 12c of the pair of retaining frames 12a, 12b engage with the elastic sheet 15, thereby more firmly fastening the retaining frames 12a, 12b and the copper wire cable 11 together via the elastic sheet 15.

[0021] FIG. 6 shows another example of an elastic sheet 21 for preventing misalignment that is interposed between the retaining frames 12a (12b). This elastic sheet 21 has a number of grooves 22 formed in its width direction, and a number of protrusions 23 formed on the surfaces of the recesses 22c of a pair of retaining frames 22a (upper part shown) and 22b are adapted to fit into these grooves 22, so that the elastic sheet 21 and the retaining frame 22a are strongly interlocked and held in place.

[0022] Incidentally, Figure 7 shows three anti-theft mechanisms 30 for the copper cables 31 assembled in parallel, and the holding frames 32a, 32b have multiple (three) grooves 33 formed in the longitudinal direction, and elastic sheets 34 are interposed in each of the grooves 33, so that the copper cables 31 are securely held. In the figure, reference numeral 35 denotes a bellows-shaped protective cover, and between these bellows-shaped protective covers 35, the copper cable 31 is firmly attached at a predetermined position via the holding frames 32a, 32b, thereby preventing theft. Of course, the protective cover 35 need not have a bellows-like structure, and may not have a bellows-like structure.

[0023] FIG. 9 is a schematic cross-sectional view showing a main part of a further embodiment of an anti-theft mechanism for a copper cable according to the present invention, and FIG. 10 is a schematic plan view thereof. 9 and 10, a pair of holding frames 112a, 112b that clamp the copper cable 111 from both sides are shown. On both sides of the copper cable insertion groove 113 of the holding frames 112a and 112b, there are provided screw holes 116 for attaching fastening means consisting of a bolt 114 and a nut 115.

[0024] FIG. 11 is a schematic front view and a schematic side view showing one embodiment of the copper cable anti-theft mechanism of the present invention or a demonstration device for the copper cable anti-theft mechanism. In the schematic front view of Fig. 11, the copper cable anti-theft mechanism of the present invention is a copper cable (copper wire) and an anti-theft mechanism 121 of a copper cable with a flex pipe of a predetermined length connected to both sides are buried in a predetermined site G (ground). The flex pipe is preferably 5 to 8 m long. That is, FIG. 11 shows that a copper cable anti-theft mechanism 121 and a copper cable (C) are buried, with flex pipes of a given length (see FIG. 14 and FIG. 15) connected to both sides. The copper cable anti-theft mechanism demonstration device 131 thus constructed comprises an anti-theft stopper 132 with gate-shaped legs 133, and has a holding frame 134 made of a substantially cylindrical flexible pipe fixed to the upper part of the anti-theft stopper 132, so that a copper cable (C) can be inserted inside the holding frame 134. Then, the copper cable (C) is inserted into the holding frame 134, and the gate-shaped legs 133 of the anti-theft stopper 132 are inserted into the specified site G and fixed therein.

[0025] A partition bar 135 of a specified width is arranged horizontally and fixed to a pair of gate-shaped legs 133 on the left and right sides at approximately the middle position of the cylindrical holding frame 134, and a copper cable (C) is inserted on both the top and bottom sides of the bar to enable simple and space-saving holding.

[0026] 11, the cylindrical support frame 134 is further shown to have a corrugated cross section, the corrugations 136 of which greatly increase the strength of the cylindrical support frame 134.

[0027] More specifically, as shown in the schematic oblique views of Figures 12 and 13, the cylindrical holding frame 134 has a further folded cross section, and by screwing and fixing a band-shaped fastener 137 to this corrugated portion 136 on a support bracket 138 attached to the lower part of the cylindrical holding frame 134, the role of the cylindrical holding frame 134 is greatly improved. In the figure, C is a copper cable.

[0028] Next, reference will be made to the schematic cross-sectional view of FIG. 13, which shows the details of the method of assembling the copper cable anti-theft mechanism of the present invention or the copper cable anti-theft mechanism demonstration device. 14 and 15 show that a depression H (hole) is excavated on a specific site G so as to be slightly wider than the width of the copper cable anti-theft mechanism 121. Excavated soil ES is piled up around the depression H. In this depression H, the copper cable anti-theft mechanism 121 with cylindrical holding frames 134 attached to both sides and the copper cable (C) are arranged so as to be exposed, and then the excavated soil ES is backfilled. By appropriately digging in the above state, the copper cable can be pulled out, which can be useful for preventing theft of the copper cable. Similarly, the copper cable theft prevention mechanism itself serves as a demonstration device 131 for the copper cable theft prevention mechanism. Of course, this copper cable anti-theft mechanism demonstration device 131 is equipped with gate-shaped legs 133 and an anti-theft stopper 132 that allows a copper cable (C) to be inserted inside a holding frame 134 provided on the upper part of the device, and by inserting the copper cable (C) into the holding frame 134 and fixing the gate-shaped legs 133 of the anti-theft stopper 132 into the specified site G, it is possible to prevent the theft of the copper cable. Therefore, it goes without saying that the above-mentioned copper cable anti-theft mechanism demonstration device 131 can be used as an anti-theft mechanism for copper cables as it is.

[0029] FIG. 13 is a schematic cross-sectional view showing the main parts of the copper cable anti-theft mechanism of the present invention, showing a copper cable (C) and a copper cable anti-theft mechanism 121 connected to a holding frame 134 made of a substantially cylindrical flex pipe on both sides. 13, the gate-shaped legs 133 of the anti-theft stopper 132 are inserted and fixed on both sides of the excavated depression H. Between them, the anti-theft mechanisms 121 made of copper cables are set on the upper and lower copper cables (C). In FIG. 13, reference numeral 141 denotes a support plate laid in the excavated depression H, and reference numeral 142 denotes a fixing member for the support plate.

[0030] Furthermore, the demonstration device for the copper cable anti-theft mechanism of the present invention has the above-mentioned configuration, and allows the copper cable anti-theft mechanism to be visually observed in a very easy-to-understand form, allowing users to quickly understand it in a very convenient and beneficial situation. [Industrial Applicability]

[0031] As described above, the present invention makes it possible to provide a more reliable anti-theft mechanism for copper cables using a very simple mechanism, and also to provide a demonstration device for the anti-theft mechanism for copper cables.

[0032] Furthermore, since the copper cable anti-theft mechanism of the present invention or a demonstration device for the copper cable anti-theft mechanism can be installed near the location where the copper cables are arranged, a very easy-to-use product can be obtained. [Explanation of symbols]
