Shock absorber used in power transmission and distribution cable support devices for power conduits

[0001] The present invention relates to a shock absorption device used in a power transmission and distribution cable support device for a power conduit, and more specifically, to a technology that supports the lower part of a power transmission and distribution cable installed in a power conduit while absorbing shocks such as earthquakes to ensure safety, such as preventing short circuits in the power transmission and distribution cable.

[0002] Typically, a power conduit is buried underground to protect underground power lines, and power transmission and distribution cables are buried inside the power conduit; however, a power transmission and distribution cable support device is installed to support or protect the power transmission and distribution cables more stably.

[0003] Such power transmission and distribution cable support devices are generally composed of a structure in which the lower part of the power transmission and distribution cable can be seated, a structure that wraps the outer side of the power transmission and distribution cable excluding the upper part, or a structure that covers and fixes the upper part after the power transmission and distribution cable is seated.

[0004]

[0005] First, if we look at conventional technologies,

[0006] Registration No. 10-10-2345888 (Patent) As filed by the applicant of the present invention, a power transmission and distribution cable support device for a power conduit comprises: a base plate having an outer shape that is rectangular and divided into two equal parts, wherein the base plate is configured to be disposed on the inner bottom portion of a power conduit and has a rectangular groove formed on its upper portion, and a first groove and a second groove are sequentially formed in the central portion, wherein the second groove is formed larger than the first groove so as to allow the cable seating portion to move, and a plurality of fixing portions on the outer side which are configured to be seated on the groove portion; A cable seating portion comprising: first and second cable seating portions arranged facing each other to form a cable seating groove between them, wherein the lower portion is fitted into the first and second grooves and is formed smaller than the first and second grooves so as to be able to move to one side or the other on the first and second grooves, wherein an elastic member insertion groove is formed on the lower portion and a roller is formed on the upper portion of the surfaces of the first and second cable seating portions facing each other, and an elastic member having a pulling property is formed in the elastic member insertion groove, so that when a cable is drawn into the cable seating groove, it moves downward while riding the roller, is pushed in the opposite direction to the first and second cable seating portions facing each other, is completely seated in the cable seating groove, and then is restored to its original state; and a cover portion is formed on the upper portion of the first cable seating portion, wherein one end is hinge-coupled to rotate around the hinge and a locking projection is formed on the other end, thereby selectively opening or closing the upper portion of the cable seating groove, and the The technology relates to a power transmission and distribution cable support device for a power conduit having a self-fixing force that fixes the first and second cable mounting parts without spreading apart in opposite directions when the cable mounting groove is sealed, such that when the cable mounting groove is closed, the locking projection contacts and is fixed to the outer side of the second cable mounting part.

[0007]

[0008] The aforementioned prior art primarily describes an assembly structure in which, when each power transmission and distribution cable is individually seated, an elastic member is pulled in both directions to create an insertion space, and when the power transmission and distribution cable is seated in the insertion space, the elastic member is restored to secure it.

[0009] However, although the aforementioned technology is a structure in which seating and fixation can be achieved by the elastic force of the elastic member, there is a problem in that it is inevitably vulnerable to earthquakes when applied to power conduits.

[0012] The technical feature is that it further includes an auxiliary elastic body (500) configured in the slide hole (111), between the upper part of the first body (310) and the lower part of the second body (320), and between the upper part of the second body (320) and the lower part of the third body (330).

[0013] The technical feature is that a second elastic pad (600) is formed wholly or partially on the inner surface where the first, second, and third central grooves (311, 321, 331) of the first, second, and third bodies (310, 320, 330) are formed.

[0014] According to the shock absorption device used in the power transmission and distribution cable support device for the present invention, the original purpose of supporting the lower part of the power transmission and distribution cable support device is maintained, and at the same time, due to the elastic members placed between each component, the transmission of shock to the cable support device side when an impact such as an earthquake occurs can be minimized, thereby preventing short circuits in the cable and ensuring safety.

[0042] The present invention provides a shock absorption device used in a power conduit power transmission and distribution cable support device, which supports the lower part of a power transmission and distribution cable installed in a power conduit while absorbing shocks such as earthquakes to ensure safety, such as preventing short circuits in the power transmission and distribution cable.

[0043]

[0044] Hereinafter, the preferred configuration and operation of the present invention for achieving the above objective in relation to the attached drawings will be described with reference to FIGS. 1 to 11 as follows.

[0045]

[0046] First, before describing the present invention, the configuration thereof is shown as illustrated in FIGS. 1 to 5. The device for protecting the lower and side of a power conduit transmission and distribution cable support device comprises: a vertical part (110) having a side formed in an "L" shape and installed in close contact with the side and bottom of the power conduit, with a plurality of slide holes (111) formed in the vertical length direction at a certain distance from the inner side; and a horizontal part (120) formed to extend horizontally from the lower part of the vertical part (110), having an elastic pad groove (121) with a certain depth formed on the upper side, and a plurality of grooves (123) formed on the upper side at a certain distance from the elastic pad groove (121); and a first elastic pad (200) inserted into the elastic pad groove (121). A first body (310) that is slidably coupled to the slide hole (100) on both sides, has a first central groove (311) formed in the central part that is aligned with the elastic pad groove (210), a plurality of first upper grooves (313) formed at regular intervals on the upper part, and a first lower groove (315) formed at the lower part that faces the first upper groove (123); a second body (320) that is slidably coupled to the slide hole (100) on both sides and is positioned on the upper part of the first body (310), has a second central groove (321) formed in the central part that is aligned with the first central groove (311), a second upper groove (323) formed at regular intervals on the upper part, and a second lower groove (325) formed at the lower part that faces the first upper groove (313); and on both sides the A support body (300) comprising a third body (330) that is slidably coupled to a slide hole and positioned on the upper part of the second body (320), wherein a third central groove (331) is formed in the central part and positioned in alignment with the second central groove (321), and a third lower groove (333) is formed in the lower part and faces the second upper groove (323), and includes a support member (335) on both upper sides that supports the sides of the support device (5);An elastic body (400) is composed of: a first elastic member (410) having one side inserted into the groove (313) and the other side inserted into the first lower groove (315); a second elastic member (420) having one side inserted into the first upper groove (313) and the other side inserted into the second lower groove (325); and a third elastic member (430) having one side inserted into the second upper groove (323) and the other side inserted into the third lower groove (333).

[0047]

[0048] To explain the lower fixing plate (100) in more detail, as shown in FIG. 5, the side is formed in an "L" shape and is installed in close contact with the side and bottom (not shown) of the power conduit (not shown) and is composed of a vertical part (110) and a horizontal part (120).

[0049]

[0050] As shown in FIGS. 1 and 2, the vertical part (110) is formed to be long in the vertical direction, and a plurality of slide holes (111) are formed on the inner surface at regular intervals in the vertical direction so that the support body (300) to be described below can be slidably coupled.

[0051] At this time, the slide holes (111) are formed in multiple numbers spaced apart at regular intervals, with at least two or more being formed to provide a strong fixing force, and the present invention is illustrated as having two formed as an example.

[0052] In addition, the slide hole (111) is formed with a vertical length extending from the upper side to the lower side, thereby providing a space into which the support body (300) is inserted, while also providing a flow space in which the support body (300) can move on the slide hole (111) by means of an elastic body (400).

[0053]

[0054] Meanwhile, as shown in FIGS. 2 and 5, the horizontal portion (120) is formed to extend horizontally from the lower part of the vertical portion (110), and an elastic pad groove portion (121) having a certain depth is formed on the upper side, and a plurality of groove portions (123) spaced apart from the elastic pad groove portion (121) are formed on the upper side, so that a space for inserting a first elastic pad (200) is provided in the elastic pad groove (121), and the lower part of an elastic body (400) can be inserted into each of the groove portions (123).

[0055] At this time, the elastic pad groove (121) is formed in the shape of a groove rather than having a completely penetrating shape, so that the first elastic pad (200) does not come into contact with the bottom part of the power conduit, thereby preventing damage to the first elastic pad (200).

[0056]

[0057] In addition, the reason the above-mentioned groove (123) is formed in multiple numbers is to ensure that the elastic body (400) can perform balanced operation when the support bodies (300) absorb shock through elastic restoring force, etc.

[0058]

[0059] As shown in FIGS. 2 and 6, the first elastic pad (200) is formed of urethane rubber material so that it is inserted into the elastic pad groove (121) and substantially contacts and supports the lower part of the cable support device, while absorbing shock so that the shock can be transmitted to the support device side with minimal impact.

[0060] In addition, the first elastic pad (200) may be composed of one or more, and if composed of multiple, the shock absorption effect can be further maximized when an impact occurs due to earthquakes, etc. In the present invention, it is illustrated as being composed of one first elastic pad (200), but the present invention is not limited to an embodiment.

[0061]

[0062] As shown in FIGS. 2, 5, 6, and 7, the support member (300) is composed of first, second, and third bodies (310, 320, 330) and is configured to be slidably coupled to the slide hole (111).

[0063] The first body (310) is slidably coupled to the slide holes (111) on both sides, and a first central groove (311) is formed in the central part and is aligned with the elastic pad groove (210), a plurality of first upper grooves (313) are formed at regular intervals on the upper part, and a first lower groove (315) is formed on the lower part facing the first upper groove (123).

[0064]

[0065] The first central groove (311) performs the function of holding the power transmission and distribution cable support device so that it does not move to one side or the other side while the support device is inserted, and the first upper groove (313) is a space for the lower part of the elastic body (400) to be inserted, and the first lower groove (315) is a space for the upper part of another elastic body (400) to be inserted.

[0066]

[0067] The second body (320) is slidably coupled to the slide holes (100) on both sides and positioned on the upper part of the first body (310). A second central groove (321) is formed in the central part and is aligned with the first central groove (311). A second upper groove (323) is formed at a certain distance from the upper part, and a second lower groove (325) is formed at the lower part and faces the first upper groove (313). This allows the second body to wrap around and protect an outer part of the power transmission and distribution cable support device while preventing the power transmission and distribution cable support device from detaching.

[0068]

[0069] The third body (330) is slidably coupled to the slide holes on both sides and positioned on the upper part of the second body (320), and is configured such that a third central groove (331) is formed in the central part in alignment with the second central groove (321), a third lower groove (333) is formed in the lower part facing the second upper groove (323), and a support member (335) that supports both sides of the support device (5) on both upper sides is included, thereby performing a similar role to the second body (320).

[0070] At this time, the support member (335) additionally supports the outer side of the power transmission and distribution cable support device (5), thereby enabling more stable fixation.

[0071] Here, as illustrated in FIG. 10, a second elastic pad (600) is formed wholly or partially on the inner surface where the first, second, and third central grooves (311, 321, 331) of the first, second, and third bodies (310, 320, 330) are formed, so that when shaking occurs due to a part of the shock transmitted to the power transmission and distribution cable support device by means of an earthquake, the shock can be mitigated by the second elastic pad (600).

[0072]

[0073] As shown in FIG. 2 and 6, the above elastic body (400) is composed of a first elastic member (410) with one side inserted into the groove (313) and the other side inserted into the first lower groove (315), a second elastic member (420) with one side inserted into the first upper groove (313) and the other side inserted into the second lower groove (325), and a third elastic member (430) with one side inserted into the second upper groove (323) and the other side inserted into the third lower groove (333).

[0074] That is, the above elastic body (400) has a first elastic member (410) positioned between the horizontal part (120) and the first body (310), a second elastic member (420) positioned between the first body (310) and the second body (320), and a third elastic member (430) positioned between the second body (320) and the third body (330), so that when an impact or vibration occurs due to earthquakes, the first, second, and third bodies (310, 320, 330) can move up and down according to the elastic restoring force by the above elastic body (400) to mitigate the impact.

[0075] At this time, it is preferable that the elastic body (400) be composed of a number corresponding to the number of the grooves.

[0076]

[0077] Meanwhile, as illustrated in FIGS. 8 and 9, an auxiliary elastic body (500) is further included in the slide hole (111), which is configured between the upper part of the first body (310) and the lower part of the second body (320), and between the upper part of the second body (320) and the lower part of the third body (330). By configuring the portions that are fitted into the slide hole (111) of the support body (300) together with the elastic body (400) in between, the support body (300) can maintain balance on both sides during normal operation and can have a more effective shock absorption effect.

[0078] At this time, in order to form the auxiliary elastic body (500), grooves (h) are formed in the parts facing each other so that both sides of the auxiliary elastic body (500) can be inserted to prevent detachment between the first, second, and third bodies (310, 320, 330), and the auxiliary elastic body (500) is fixed by fitting it into each groove (h). Additionally, to fix the lower part of the auxiliary elastic body (500) located at the lower part of the first body (310), the horizontal part (120) is configured to fix the auxiliary elastic body (500) by forming another groove (h) in the part facing the groove (h) formed at the lower part of the first body (310).

[0079] Due to the above structure, the auxiliary elastic body (500) is also fitted into the groove (h) on both sides and can perform its function smoothly without detachment.

[0080]

[0081] According to the shock absorption device used in the power transmission and distribution cable support device for a power conduit of the present invention, the original purpose of supporting the lower part of the power transmission and distribution cable support device is maintained, and at the same time, due to the elastic members placed between each component, the transmission of shock to the cable support device side when an impact such as an earthquake occurs can be minimized, thereby preventing cable short circuits and ensuring safety. FIG. 12 is a diagram showing a usage state of a preferred embodiment of the present invention.
