Description

Technical Field

[0001] The present invention relates to a mechanical device for power distribution lines on overhead utility poles, and more specifically, to a spacing damper for maintaining the mutual spacing of power distribution lines installed on overhead utility poles. Background Technology

[0002] The electricity generated by power plants is transmitted to end users via overhead power lines connected between utility poles installed at regular intervals. To improve transmission efficiency, numerous overhead power lines are connected side-by-side between the poles. However, these power lines are susceptible to damage from external factors such as wind, which can cause them to collide and collide. To reduce the vibrational energy that leads to these collisions, spacer dampers are installed at regular intervals to maintain proper spacing between the overhead power lines.

[0003] Currently, overhead power line workers install and remove bay dampers from work vehicles that travel on power distribution lines. However, the design of traditional bay dampers is not suitable for overhead power line workers to install and remove them quickly and easily on overhead power distribution lines. Summary of the Invention

[0004] The purpose of this invention is to provide a spacer damper for overhead power line distribution, which can be fastened and disengaged quickly and easily.

[0005] To accomplish the above-mentioned task, a spacing damper for maintaining the spacing between multiple power distribution lines installed on the ground is provided. The spacing damper includes: a housing having a main body and multiple wire receiving portions, the main body being arranged in the transverse direction of the direction of travel of the power distribution lines, the multiple wire receiving portions being arranged at predetermined positions radially from the main body to maintain the spacing between the multiple power distribution lines, and each accommodating one of the multiple power distribution lines; and multiple locking devices, each disposed in the multiple wire receiving portions, selectively operating between two states: a restricted state, in which the individual wires are prevented from detaching from the wire receiving portions; and a released state, in which the restricted state is released, wherein the multiple wire receiving portions of the housing each have an opening opening in the same direction along the circumference. In the restricted state and the non-released state, each of the locking devices selectively opens and closes the opening.

[0006] The housing may include a cut-off portion that cuts inward relative to the opening, allowing the power distribution wires to enter an outer contour region adjacent to the opening. Therefore, the spacer damper can guide multiple power distribution wires in a single rotation to facilitate insertion into their respective wire receiving portions.

[0007] The spacer damper may further include a fastening part with a fastening operation, wherein the plurality of locks are batch-driven by the fastening operation. Therefore, each power distribution wire inserted into each wire receiving part can be collectively restricted or released.

[0008] According to one embodiment of the invention, the spacer damper has a structure suitable for quickly and robustly securing and separating overhead power line distribution cables. Attached Figure Description

[0023] Explanation of reference numerals in the attached figures Detailed Implementation

[0024] A spacer damper 100 designed according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] Figure 1 A spacing damper 100 is shown, installed to maintain the spacing of overhead power lines 2 connected between utility poles 1. According to one embodiment of the invention, the utility pole 1 is a ground-mounted vertical device for suspending the power lines 2 in the air, including utility poles, towers, etc. of various shapes and materials. Figure 1 An example is given to the case where utility pole 1 is a tower.

[0026] Multiple power distribution lines 2 are suspended in groups between utility poles 1. In one embodiment of the invention, each group has four power distribution lines that extend parallel to each other at predetermined intervals.

[0027] The spacer damper 100 is installed laterally to maintain the spacing between the extensions of the multiple parallel overhead power distribution lines 2.

[0028] Figure 2 This is a diagram illustrating the spacer damper 100 according to a first embodiment of the present invention; Figure 3 This is an explanation Figure 2 A diagram of the internal structure of the spacer damper 100; Figure 4 This is an explanation Figure 3 The diagram shows the spacer damper 100 fixed on the overhead power line.

[0029] Please see Figures 2 to 4 The spacer damper 100 includes (but is not limited to) a rectangular housing 110, a plurality of lockers 120 and a fastener 130.

[0030] Multiple locking devices 120 and fastening parts 130 can be installed inside the housing 110. The housing 110 includes a first housing 110-1 and a second housing 110-2, which are connected by a threaded connection 115, and multiple locking devices 120 and fastening parts 130 are installed therein.

[0031] The housing 110 includes a main body 111 and four wire receiving sections 112, which are positioned to maintain the spacing between multiple power distribution wires 2 extending radially from the main body 111.

[0032] The main body 111 is installed horizontally on the extension line of the overhead power distribution line 2. The main body 111 has a protruding fastening operating part 131 at the center, which can be rotated from the outside.

[0033] Four wire receiving sections 112 may be provided at each corner of the housing 110, i.e., the four wire receiving sections 112 may be arranged symmetrically with respect to the central fastening operating point 131. The number of wire receiving sections 112 is not limited to four and may be determined according to the number of overhead power lines 2. Each of the four wire receiving sections 112 has the same unidirectional opening 113 along its circumference. Each opening 113 provided in the four wire receiving sections 112 opens in a counterclockwise direction. Of course, they may all be designed to be clockwise. The housing 110 includes an inwardly facing cut-off portion 114 in the outer region adjacent to the opening 113 for guiding the overhead power line 2 into the opening 113. Figure 3 As shown, after placing the four wire receiving parts 112 between the four overhead power distribution lines 2, rotating the housing 110 counterclockwise allows the four overhead power distribution lines 2 to move along... Figure 2 The cut-off section 114 shown is guided and enters the four wire receiving sections 112 through the opening 113. In this way, a human operator or unmanned robot can insert the four overhead power lines 2 into the four wire receiving sections 112 simply by rotating the housing 110 counterclockwise.

[0034] Each of the four locking devices 120 is used to open and close each of the four openings 113 of the four wire receiving portions 112 extending radially from the central fastening operating part 131. Each of the four locking devices 120 can be selectively operated between two states: a restricted state, in which each received power cable 2 is not removed from the wire receiving portion 112; and a released state, in which the power cable 2 is released from the restricted state. All four locking devices 120 are similar in structure, therefore only one is described.

[0035] The locker 120 includes a locking part 122 that reciprocates radially from the center of the body 111, a cylindrical operating part 123 that extends from the locking part 122 toward the center, and a spring 124 that surrounds the operating part 123 and is compressed and restored by the reciprocating motion of the locking part 122.

[0036] The wire receiving portion 112 protrudes inwardly with an engaging portion 122. The engaging portion 122 has an engaging groove 121 on the side facing the wire receiving portion 112, which engages a portion of the power distribution wire 2.

[0037] The inner diameter of the operating part 123 has a cylindrical thread, which can be threaded to the drive shaft part 134 of the fastening part 130.

[0038] Spring 124 provides radial elastic force through fastening part 130, enabling engagement part 122 to reliably pressurize and support power distribution cable 2.

[0039] The fastening part 130 includes an operation drive part 131, 132 and a transmission drive part 133, 134. The transmission drive parts 133, 134 are connected between the operation drive part 131, 132 and the plurality of locking devices 120, and are used to transmit the driving force of the operation drive part 131, 132 to each locking device 120.

[0040] The operation drive units 131 and 132 include a fastening operation unit 131 operated by the user and a ring gear 132. The ring gear 132 is arranged relative to the center of the main body 111 and rotates through the operation of the fastening operation unit 131.

[0041] The gearbox drive unit 133 includes four bevel gears 133 arranged circumferentially along the ring gear 132 and fastened to a part of the ring gear 132, and four drive shafts 134 extending from each bevel gear 133 toward the gearbox unit 112.

[0042] The transmission devices 133 and 134 are supported on the main body 111 of the housing 110, and their rotation direction is perpendicular to the rotation direction of the ring gear 132.

[0043] The drive shaft portion 134 is shaped like a shaft with threads on its outer circumference. It is fastened to the threads on the inner diameter of the operating portion 123 of the locker 120 and rotates with the rotation of the bevel gear 133. The operating portion 123 of each locker 120 moves forward or backward with the rotation of the drive shaft portion 134 of the fastening portion 130.

[0044] By operating the fastening operation unit 131, the fastening unit 130 can drive the ring gear 132 and the transmission drive units 133 and 134 to switch the state of the multiple locks 120 together.

[0045] Below, we will refer to Figure 3 and Figure 4 The operation of the spacer damper 100 according to the first embodiment of the present invention is described.

[0046] like Figure 3 As shown, the user clamps four power distribution wires 2 between four wire receiving parts 112, and then rotates the spacer damper 100 counterclockwise to insert each power distribution wire 2 into the four wire receiving parts 112 at each corner.

[0047] The user uses a wrench or similar tool to rotate the fastening mechanism 131. In another example, an unmanned robot equipped with a wrench or similar device can rotate the fastening mechanism 131. Figure 4 As shown, the ring gear 132 rotates in response to the rotation of the fastening operating part 131, each bevel gear 133 rotates in response to the rotation of the ring gear 132, and each drive shaft 134 rotates in response to the rotation of each bevel gear 133. The rotation of each drive shaft 134 causes each operating part 123 fastened thereto to move toward the wire receiving part 112, and causes the engaging part 122 fastened on the operating part 123 to move toward the wire receiving part 112, thereby fastening each engaging groove 121 to the power distribution wire 2 received in each wire receiving part 112. In another example, the operating part 123 and the engaging part 122 can be integrally formed. Therefore, the four locking devices 120 can selectively operate between two states: a restricted state in which each power distribution wire 2 cannot disengage from its respective wire receiving part 112; and an unrestricted state in which the power distribution wire 2 can be released from the restricted state. Furthermore, by rotating the central fastening operating part 131, the four locking devices 120 can be operated in batches between the restricted and unrestricted states.

[0048] In a variant embodiment, the drive shaft portion 134 of the fastening portion 130 can be replaced with a cylindrical shape with threads on its inner circumference, and the operating portion 123 of the locker 120 can be replaced with a shaft shape with threads on its outer circumference.

[0049] Figure 5 This is a schematic diagram of the internal structure of the spacer damper 200 according to the second embodiment of the present invention. Figure 6 yes Figure 5 A schematic diagram showing the spacer damper 200 fixed to the power distribution line 2. (The following text will omit the connection to the diagram.) Figure 3 Description of the same structure as the spacer damper 100 in the first embodiment shown.

[0050] Each of the four locking devices 220 can cover the opening 213 of each of the four wire receiving portions 212 that is radially spaced from the central fastening operating portion 131. The four locking devices 220 can selectively operate between a constrained state and an unconstrained state; in the constrained state, each wire 2 is prevented from detaching from the wire receiving portion 212; in the unconstrained state, the wire 2 is released from the constrained state. All four locking devices 220 have similar structures, therefore only one will be described.

[0051] The locking device 220 includes an arc-shaped locking arm 221 on which a worm gear 221G is mounted, and a drive shaft 222 on which a worm 222G is mounted and fastened to the worm gear 221G. The worm gear 221G of the locking arm 221 can be disposed at least on a portion of the outer circumferential surface of the worm gear of the drive shaft 222.

[0052] The locking arm 221 can be installed in the guide arm 212G of the housing 210 and can rotate along the outer circumference of the power distribution wire 2 installed in the wire receiving part 212.

[0053] The guide arm 212G has an annular recess to receive rotation of the arc-shaped locking arm 221. For example... Figure 5 As shown, the pivot center O' of the locking arm 221 maintains a predetermined distance from the center O of the wire receiving portion 212 in the direction of travel, opposite to the direction of the opening 213. In this way, the locking arm 221 used to open and close the opening 213 can be more closely aligned with the outer peripheral surface of the distribution line 2 of the opening 213.

[0054] The drive shaft 222 has a worm 222G, which is rod-shaped and is fastened to the worm wheel 221G of the locking arm 221, and coupled to the bevel gear 233 of the fastening part 230. The drive shaft 222 can rotate about a radial axis according to the rotation of the bevel gear 233, thereby rotating the locking arm 221.

[0055] The fastening part 230 includes operation drive parts 231, 232 and transmission drive parts 233, 234. The transmission drive parts 231, 232 are connected to a plurality of locks 220 for transmitting the actuation force of the operation drive parts 231, 232 to each lock 220.

[0056] The operation drive units 231 and 232 include a fastening operation unit 231 operated by the user and a ring gear 232. The ring gear 232 is disposed relative to the center of the main body 211 and rotates through the operation of the fastening operation unit 231.

[0057] The transmission drive unit 233 includes four bevel gears 233 arranged along the circumference of the ring gear 232 and fastened to a part of the ring gear 232, and four tapered shaft portions 234 extending from each bevel gear 233 toward the wire receiving portion 112.

[0058] The transmission drive units 233 and 234 are supported on the main body 111 of the housing 110, and their rotation direction is perpendicular to the rotation direction of the ring gear 232.

[0059] The tapered shaft 234 is connected to the drive shaft 222 of the locker 220.

[0060] By operating the fastening operation unit 231, the fastening unit 230 can activate the ring gear 232 and the transmission drive units 233 and 234, thereby jointly switching the state of multiple locks 220.

[0061] The following will refer to Figure 5 and Figure 6 The operation of the interval damper 200 according to the second embodiment of the present invention is described.

[0062] like Figure 5 As shown, the user or unmanned robot inserts each of the four wire receiving parts 212 into the four wire receiving parts 212 at each corner by clamping the four wire receiving parts 212 between the four power distribution wires 2 and rotating the spacer damper 200 counterclockwise.

[0063] Users or unmanned robots use tools such as wrenches to rotate and tighten the operating part 231. Figure 6 As shown, the ring gear 232 rotates with the rotation of the fastening operation part 231, each bevel gear 233 rotates with the rotation of the ring gear 232, the worm 222G of each drive shaft part 222 rotates with the rotation of each bevel gear 233, and the rotation of each worm 222G drives the worm wheel 221G of each locking arm 221 fastened thereto, and the rotation of each locking arm 221 closes the opening 213 of each rolling element 212. In this way, the four locking devices 220 can be selectively operated between two states: a constrained state, in which each power cable 2 cannot detach from its respective wire receiving part 212; and an unconstrained state, in which the power cable 2 can be released from the constrained state. In addition, the four locking devices 220 can be operated in batches between the constrained and unconstrained states by rotating the central fastening operation part 231.

[0064] Figure 7 This is a schematic diagram of the internal structure of the spacer damper 300 according to the third embodiment of the present invention. Figure 8 yes Figure 7 A schematic diagram showing the spacer damper 300 fixed to the power distribution line 2. (The following will omit details regarding the connection between the damper 300 and the power distribution line 2.) Figure 5 The second embodiment shown has the same structure as the spacer damper 200.

[0065] The locking device 320 includes an arc-shaped locking arm 321, with a pinion 321G at its outer circumferential end, and a drive shaft 322, on which a rack 322G is fastened to the pinion 321G.

[0066] The drive shaft 322 has a rack 322G, which is rod-shaped and is fastened to the pinion 321G of the locking arm 321, and is located inside the drive tube 334 of the fastening part 330. The drive shaft 322 can move forward and backward along the radial axis as the drive tube 234 rotates.

[0067] The fastening part 330 includes an operation drive part 331, 332 and a transmission drive part 333, 334. The transmission drive part 331, 332 is connected to a plurality of locks 320 for transmitting the actuation force of the operation drive part 331, 332 to each lock 320.

[0068] The drive components 331 and 332 include a clamping mechanism 331 operated by the user and a ring gear 332. The ring gear 332 is arranged relative to the center of the body 311 and is rotated by the clamping mechanism 331.

[0069] The gearbox drive unit 333 includes four bevel gears 333 arranged circumferentially along the ring gear 332 and mating with a part of the ring gear 332, and four drive tubes 334 extending from each bevel gear 333 toward the gearbox unit 312.

[0070] The transmission drive units 333 and 334 are supported on the main body 311 of the housing 310, and their rotation direction is perpendicular to the rotation direction of the ring gear 332.

[0071] The transmission drive units 333 and 334 are supported on the main body 311 of the housing 310, and their rotation direction is perpendicular to the rotation direction of the ring gear 332.

[0072] The inner circumference of the drive tube 334 is threaded, which can be fastened to the thread on the outer diameter of the drive shaft 322 of the locking device 320, and rotates with the rotation of the bevel gear 333. The drive shaft 322 of each lock 320 can move forward or backward along the radial axis as the drive tube 334 of the fastening part 330 rotates.

[0073] The fastening part 330 can activate the ring gear 332 and the transmission drive parts 333 and 334 through the operation of the fastening operation part 331, so as to switch the state of multiple lockers 320 in batches.

[0074] The tapered shaft 334 is connected to the drive shaft 322 of the locker 320.

[0075] The fastening part 330 can activate the ring gear 332 and the transmission drive parts 333 and 334 through the operation of the fastening operation part 331, so as to switch the state of multiple lockers 320 in batches.

[0076] The following will refer to Figure 7 and Figure 8 The operation of the interval damper 300 according to the third embodiment of the present invention is described.

[0077] like Figure 7As shown, the user or autonomous robot clamps the four wire receiving parts 312 at each corner between the four power distribution wires 2, and then rotates the spacer damper 300 counterclockwise to insert each power distribution wire 2 into each wire receiving part 312.

[0078] Users or unmanned robots use tools such as wrenches to rotate and tighten the operating part 331. Figure 8 As shown, the ring gear 332 rotates with the rotation of the fastening operation part 331, each bevel gear 333 rotates with the rotation of the ring gear 332, each drive tube part 334 rotates with the rotation of each bevel gear 333, the rack 322G of each drive shaft 322 moves forward or backward with the rotation of each drive tube part 334, the pinion 321G of each locking arm 321 is fastened with the forward or backward movement of each rack 322G, the pinion 321G of each locking arm 321 is fastened, and the opening 313 of each wire receiving part 312 is closed by each locking arm 321 as the pinion 321G of each locking arm 321 is fastened. In this way, the four locking devices 320 can selectively operate between two states: a constrained state, in which each distribution wire 2 cannot detach from its respective wire receiving part 312; and an unconstrained state, in which each distribution wire 2 can be released from the constrained state. Furthermore, by rotating the central fastening operating part 331, the four locking devices 320 can be operated in batches between the restricted and unrestricted states.

[0079] Figure 9 This is a schematic diagram of the internal structure of the spacer damper 400 according to the fourth embodiment of the present invention. Figure 10 yes Figure 9 A schematic diagram showing the spacer damper 400 being fastened to the distribution line 2. The following will omit details regarding the method used. Figure 7 The third embodiment of the spacer damper 300 shown has the same structure.

[0080] The locking arm 420 includes an arc-shaped locking arm 421, a connecting rod 422, and a drive shaft 423.

[0081] One end of the connecting rod 422 is hinged to the locking arm 421, and the other end is hinged to the drive shaft 423.

[0082] Now for reference Figure 9 and Figure 10 The operation of the interval damper 400 according to the fourth embodiment of the present invention is described.

[0083] like Figure 9 As shown, the user or unmanned robot inserts each of the four wire receiving parts 412 into the four wire receiving parts 412 at each corner by clamping the four wire receiving parts 412 between the four power distribution wires 2 and rotating the spacer damper 400 counterclockwise.

[0084] Users or unmanned robots use tools such as wrenches to rotate and tighten the operating part 431. Figure 10 As shown, the ring gear 432 rotates in response to the rotation of the fastening operation part 431, each bevel gear 433 rotates in response to the rotation of the ring gear 432, each drive tube part 434 rotates in response to the rotation of each bevel gear 433, each drive shaft 423 advances or retracts along the radial axis in response to the rotation of each drive tube part 434, and in response to the advance or retraction of the drive shaft part 423, the first end of each linkage part 422 is hinged and pivots and advances or retracts. When the other end of the linkage part 422 is hinged and pivots and advances or retracts, each locking arm 421 is hinged and pivots. In response to the pivoting of each locking arm 421, the opening 413 of each wire receiving part 412 closes. In this way, the four locking devices 420 can selectively operate between a constrained state and an unconstrained state. In the constrained state, each distribution wire 2 is prevented from disengaging from each wire receiving part 412, and in the unconstrained state, each distribution wire 2 is released from the constrained state. Furthermore, by rotating the central fastening operating part 431, the four locking devices 420 can be switched in batches between restricted and unrestricted states.

[0085] Figure 11 This is a schematic diagram of the internal structure of the spacer damper 500 according to the fifth embodiment of the present invention. Figure 12 yes Figure 11 A schematic diagram showing the spacer damper 500 fixed to the power distribution line 2. (The following will omit details related to...) Figure 3 Description of the same structure as the spacer damper 100 in the first embodiment shown.

[0086] Each of the four locking devices 520 is arranged to open and close each of the four openings 513 of the four wire receiving sections 512 radially from the central fastening operating section 531. The four locking devices 520 can selectively operate between two states: a restricted state in which each installed distribution tube 2 does not detach from the wire receiving section 512, and an unrestricted state in which the conduit is released from the restricted state. Since all four locking devices 520 have similar structures, only one will be described.

[0087] The joystick 520 includes a locking protrusion 521 that is inserted into a protruding receiving portion 514 extending radially from the center of the body 511 and reciprocates, a spring 522 that is compressed and returns to its original shape during the reciprocating motion of the locking protrusion 521, and an operating portion 523 that reciprocates radially from the center of the body 511 around the locking protrusion 521.

[0088] The locking protrusion 521 is supported by a spring 522 and protrudes to occupy a portion of the opening 513. When the power cable 2 passes through the opening 513 and is inserted into the protrusion receiving portion 514, the locking protrusion 521 is squeezed by the power cable 2. After the power cable 2 is inserted into the wire receiving portion 512, the locking protrusion 521 protrudes into the opening 513.

[0089] The spring 522 can be compressed and restored according to the pressure and decompression of the locking protrusion 521.

[0090] The operating part 523 has a cylindrical thread on its inner diameter, which can be threaded to the drive shaft part 534 of the fastening part 530.

[0091] Fastener 530 and Figure 3 The fastening part 130 in the middle has the same structure, so it will not be described again.

[0092] Now please see Figure 11 and Figure 12 The operation of the interval damper 500 according to the fifth embodiment of the present invention will be described.

[0093] like Figure 11 As shown, the user or unmanned robot clamps the four wire receiving portions 512 at each corner between the four distribution wires 2, and then rotates the spacer damper 500 counterclockwise to insert each distribution wire 2 into each wire receiving portion 512. At this time, the locking protrusion 521 extends from the opening 513, confining each distribution wire 2 within its respective wire receiving portion 512.

[0094] The user or unmanned robot rotates the fastening operating part 531. For example... Figure 12 As shown, the ring gear 532 rotates in response to the rotation of the fastening operating part 531, each bevel gear 533 rotates in response to the rotation of the ring gear 532, and each drive shaft part 534 rotates in response to the rotation of each bevel gear 533. The rotation of each drive shaft part 534 causes each fastening operating part 523 to move toward the locking protrusion 521. The operating part 523 moves forward continuously to push up the locking protrusion 521, thereby completely blocking the opening 513 with the locking protrusion 521 and fixing the locking protrusion 521. In this way, since the locking protrusion 521 is firmly fixed by the fastening part 530, the power distribution cable 2 can be prevented from falling off the wire receiving part 512.

[0095] Figure 13 This is a schematic diagram illustrating the internal structure of the spacer damper 600 according to the sixth embodiment of the present invention. Figure 14 This is an explanation Figure 13 A schematic diagram showing the spacer damper 600 fixed to the power distribution line 2. (The following will omit details related to...) Figure 11 Description of the same structure as the spacer damper 500 in the fifth embodiment shown.

[0096] Four locking devices 620 are used to open and close each of the four openings 613 of the four wire receiving portions 612 extending radially from the central fastening operating part 631. The four locking devices 620 can operate selectively between two states: a restricted state, in which each received power cable 2 will not detach from the wire receiving portion 612; and an unrestricted state, in which each received power cable 2 is released from the restricted state. Since all four locking devices 620 have similar structures, only one will be described.

[0097] The locker 620 includes a locking fastening part 622 and a movable part 623. The former reciprocates radially from the center of the body 611 along the axis from the locking fastening part 622, and the latter extends from the locking fastening part 622 toward the drive shaft part 634 of the fastening part 630.

[0098] The locking engagement portion 622 includes an engagement groove 621 on a first side that engages with a portion of the power distribution wire 2 and is connected to the conductor portion 612, and an engagement protrusion 624 on a second side that engages with the opening 613. The engagement protrusion 624 includes a recessed engagement groove 614 located on a third side opposite to the second side and engaging with the opening 613. When the locking engagement portion 622 moves toward the center of the body 611, the engagement protrusion 624 can be inserted into the engagement groove 614.

[0099] The locking engagement portion 622 forms part of the wire receiving portion 612 and is capable of reciprocating along the radial axis to extend or retract the wire receiving portion 612. At the same time, when the locking engagement portion 622 reciprocates along the radial axis, it can open or close the opening on the wire receiving portion 612.

[0100] The operating part 623 has a cylindrical thread on its inner diameter, which can be threadedly connected to the drive shaft part 634 of the fastening part 630.

[0101] Fastener 630 and Figure 11 The fastening part 530 in the middle has the same structure, so it will not be described again.

[0102] Now please see Figure 13 and Figure 14 The operation of the interval damper 600 according to the sixth embodiment of the present invention will be described.

[0103] like Figure 13 As shown, the user or unmanned robot clamps the four wire receiving parts 612 at each corner between the four power distribution wires 2, and then rotates the spacer damper 600 counterclockwise to insert each power distribution wire 2 into each wire receiving part 612.

[0104] The user or unmanned robot rotates the fastening operating part 631. For example... Figure 14As shown, the ring gear 632 rotates in response to the rotation of the fastening operation part 631, each bevel gear 633 rotates in response to the rotation of the ring gear 632, each drive shaft part 634 rotates in response to the rotation of each bevel gear 633, and the rotation of each drive shaft part 634 causes each fastening operation part 623 to be pulled, and the locking engagement part 626 completely closes the opening 613, thereby confining the power distribution cable 2 within the telecommunications housing part 612.

[0105] Although preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the specific embodiments described above. Those skilled in the art can make various modifications without departing from the spirit of the present invention as claimed in the claims, and these modifications should not be understood in a way that departs from the technical concept or viewpoint of the present invention.
