Description

Earthquake-resistant electric pole with anti-fall function

The present invention relates to a seismic type telephone pole, and more particularly, it has an elastic deformation capable of efficiently absorbing vibrations generated during an earthquake, and a fall prevention function capable of minimizing damage by preventing fall. It relates to an earthquake-resistant telephone pole.

The power produced by the power plant is transmitted to each regional substation through transmission lines including large-scale transmission towers, etc., and then is supplied to demanders such as neighboring factories, buildings, or apartments through various stages of transformation process at the substation.

The most common method for supplying electric power to a consumer is to install a power pole on the ground at necessary intervals, and hang a cable on the pole and fix it. In order to connect the cable to the telephone pole, the end of the cable is fixed to the insulator installed on the top of the telephone pole, and the cables are connected with jumper wires. An insulator is an electrical component that maintains electrical insulation and maintains a physical gap or provides support.

On the other hand, telephone poles are mostly made of reinforced concrete structures and have a length of 14 to 16 meters. The lower part is embedded in the ground and fixed, and at the upper part, wancheol, insulators and transformers are installed. Since the tension of the power cable or communication cable is always applied to the telephone pole, a design is applied to prevent breakage due to the tensile force.

However, when a strong external force is applied due to a natural disaster such as an earthquake or a large typhoon, the telephone pole is often broken. The reason why the telephone pole breaks is that the stress corresponding to the applied force accumulates and exceeds the critical limit. For example, if the stress does not accumulate and is relieved momentarily, the fracture phenomenon does not occur. However, conventional telephone poles have a simple rod structure and have little function of distributing stress against external force, so they are easily broken.

As a background technology related to a telephone pole having a seismic function, Korean Patent Publication No. 10-2145792 (distribution telephone pole installation system with a seismic function) has been disclosed.

The disclosed installation system is installed in close contact with the outer circumferential surface of the telephone pole, and the protective cover is formed with a sliding groove; It is fixed to the ground by piles, and rollers are fixed to both sides of the upper floor guide plate on which the guide groove is formed and on both sides of the square frame to be connected to the sliding groove and the guide groove, and flow along the sliding groove and the guide groove due to external impact. In the electric distribution pole installation system with a seismic function consisting of a reinforcing rod, it further includes a detachable portion for fixing the pile to the ground or separating the pile from the ground, the pile has a groove portion formed at the top, and fastening holes at both sides forming the groove Is formed, the detachable portion is disposed on the upper portion of the pile, a fixed bar in which a hollow communicating with the groove portion is formed; A guide bar having both ends passing through both sides of the fixing bar and having a central portion positioned in the hollow; A binding member for binding the guide bar to the fixing bar; It is coupled to the guide bar to be movable in the longitudinal direction so as to be positioned in the hollow, and includes a pair of pressure bars having a fastening protrusion leading into the fastening hole at the bottom and a spring coupled to the outside of the guide bar to be positioned between the pair of pressure bars. And, the spring contracts as the pair of pressure bars is pressed in the opposite direction so that the lower part of the pair of pressure bars is drawn into the hollow, while the pair of pressure is released while releasing the pressure on the pair of pressure bars. The bar is bound with a fixed bar, and the fixed bar has a structure in which the pile is rotated according to the rotation and fixed to the ground or separated from the ground.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

The seismic type telephone pole having a fall prevention function of the present invention has a structure that does not fall or break even when natural disasters such as earthquakes or typhoons occur. This is possible because the telephone pole is assembled with a plurality of standing pipes and a cover member, and because the standing pipe can move relative to the inside of the cover member, no stress is accumulated.

The basic structure of the seismic telephone pole of the present invention comprises: a support means fixed on the ground and providing a support force; A plurality of standing pipes that extend upwardly while being fixed to the support means, and which are symmetrical to each other; A column assembly having a plurality of cover members enclosing the standing pipe in a mutually assembled state at the top of the supporting means, and opening the upper end of the standing pipe to the top; A coupling portion surrounding and tightening the cover member to maintain a coupled state of the cover member; A filler filling the inner space of the cover member to prevent penetration of foreign substances; An insulating body mounted on the upper end of the column assembly and having a receiving space for receiving and fixing the upper end of the column assembly, a lightning rod fixed to the outside of the insulating body, and located in the receiving space of the insulating body and electrically at the upper end of the standing pipe.

In addition, FIG. 3 is a cross-sectional view taken along line A-A of FIG. 1, and FIG. 4 is a cross-sectional view showing the internal structure of the upper cap shown in FIG. 1. And, Figure 5 is an exploded perspective view showing the configuration of the fall prevention part of Figure 1, Figure 6 is a view for explaining the operation method of the fall prevention part of FIG.

As shown, the seismic type telegraph pole 10 having a fall prevention function according to the present embodiment, a support means, three standing pipes 21, a column assembly 12, a coupling part 17, a filler 23 , The upper cap 25, and includes a fall prevention part (31).

The supporting means is fixed on the ground (G) and provides a supporting force, and takes the form of a hollow pipe having a constant diameter. The supporting means in this embodiment is a hollow supporter (19). The hollow supporter 19 has a certain diameter, the lower part is buried in the ground, the upper part is exposed to the ground and extends vertically to the upper part.

The hollow supporter 19 maintains a vertical state by receiving earth pressure. The outer diameter of the hollow supporter 19 is the same as the diameter of a general telephone pole. In addition, the depth buried in the ground by the hollow supporter 19 is the same as in the case of the previous telegraph pole.

The standing pipe 21 is a structure extending in the longitudinal direction and has a vertical extension part 21a, a horizontal extension part 21c, and a bending part 21e. The vertical extension part 21a is a part extending vertically upward through the inside of the hollow supporter 19, and the three vertical extension parts 21a are in line contact with their backs.

The three vertical extensions 21a are in line contact but are not fixed. For example, when a lateral force is applied to the upper end of the vertical extension 21a, the vertical extension 21a can move each other. This means that when a force is applied from the outside, it absorbs the applied force. If the vertical extension 21a is fixed by welding or the like, the vertical extension 21a will be bent.

The bending portion 21e is a curved portion connecting the vertical extension portion 21a and the horizontal extension portion 21c and is elastically deformable. That is, when an external force is applied, the curvature of the bending portion 21e can be elastically deformed. In other words, as shown in FIG. 6, when the telephone pole 10 is inclined in the direction of the arrow z, it is elastically deformable.

The horizontal extension part 21c is a part extending in the horizontal direction from the bending part 21e. The horizontal extension part 21c extends in a radial direction around the hollow supporter 19 from the lower part of the hollow supporter. The horizontal extension 21c suppresses the movement of the standing pipe by receiving earth pressure while being buried in the ground. That is, to prevent the vertical extension (21a) from falling over in a state that maintains the vertical.

In addition, the anchor block 22 is fixed to the extension end of each horizontal extension 21c. The anchor block 22 is a block formed of concrete and more stably fixes the standing pipe 21 to suppress movement.

The column assembly 12 is formed by connecting a plurality of cover members 14, and surrounds the standing pipe in a mutually assembled state. Each cover member 14 takes the shape of a partial cylinder of the same size and is connected in a circumferential direction. In this embodiment, three cover members 14 are attached to take the shape of a single cylinder. A protrusion 14a and a groove 14b are formed at both ends of each cover member 14, respectively. This cover member 14 is molded and manufactured from concrete.

The protrusion 14a is fitted into the groove 14b of the adjacent cover member 14. Since the protrusions 14a are fitted into the grooves 14b, there is no misalignment between the cover members 14. In addition, as shown enlarged in FIG. 3, a seal 15 is interposed between each cover member 14. The seal 15 prevents the cover member 14 from hitting directly, thereby preventing the cover member 14 from being broken or broken.

In addition, the cover member 14 forms a two-layer structure in the vertical direction. That is, three cover members 14 are located on the upper portion of the hollow supporter 19, and the other three cover members 14 are installed thereon. It goes without saying that the number of layers of the cover member 14 varies depending on the height of the telephone pole 10.

The upper end of the column assembly 12 composed of the cover member 14 is open. The standing pipe 21 is exposed to the top. The reason for exposing the standing pipe 21 to the top will be described later.

This column assembly 12 is mounted on the top of the hollow supporter (19). In addition, a transmission facility is fixed to the upper end of the column assembly 12. The transmission facility includes a wancheol 61, a plurality of insulators 63 installed in the wancheol 61 and connected to the cable 65, and a plurality of transformers 67 connected to the cable 65. These transmission facilities correspond to the transmission facilities installed in the existing telephone poles and can be changed. In addition, communication facilities may be installed together with transmission facilities, or only communication facilities may be installed without transmission facilities.

The coupling portion 17 surrounds and tightens the cover member 14 to maintain the coupling state of the cover member, and includes a coupling band 17a, a bolt 17c, and a nut 17d.

The coupling band 17a is formed by bending a strip-shaped iron plate having a certain width and thickness, and has bent ends 17b at both ends. A hole (no reference numeral) through which the bolt 17c passes is formed in the bent end portion 17b. With the coupling band (17a) surrounding the cover member (14) and facing the bent end (17b), by inserting a bolt (17c) to the bent end (17b) and filling the opposite side energy nut (17d), The band 17a binds and fixes a plurality of cover members 14 into one. The installation spacing of the coupling band 17a may vary as much as necessary.

In addition, a filler 23 is filled inside the column assembly 12. The filler 23 is an interior material made of soft silicone or rubber and seals the standing pipe 21. In addition, each of the standing pipes 21 is separated from the cover member 14 by a filler 23. As described above, since the pillar assembly 12 is filled with the filler 23, the impact transmitted to the cover member 14 is absorbed by the filler 23 and is hardly transmitted to the standing pipe 21.

On the other hand, the upper cap 25 is covered on the upper end of the column assembly 12 to protect the standing pipe 21, an insulating body (25a), a lightning rod (25g), a connecting member (25f), a connection wire (25e) It consists of

The insulating body 25a is molded of synthetic resin and has a receiving space 25b at the bottom. The accommodation space 25b is a space for accommodating the upper end of the column assembly 12. The insulating body 25a may be made of rubber or ceramic in addition to synthetic resin.

The connection member 25f is built in the accommodation space 25b. The connecting member 25f is a conductive member electrically connected to the standing pipe 21. As long as it can be electrically connected to the standing pipe 21, the shape of the connecting member 25f may be different. The connecting member 25f can be made of copper.

In addition, the lightning rod 25g is fixed in the upper center of the insulating body 25a. The function of the lightning rod (25g) itself is the same as that of a general lightning rod. The lightning rod 25g is connected to the connection member 25f through a connection wire 25e. Eventually, when lightning strikes the lightning rod 25g, the current of the lightning flows into the ground through the connection wire 25e, the connection member 25f, and the standing pipe 21. By installing the lightning rod (25g) in this way, the transformer 67 is not hit by lightning.

On the other hand, the fall prevention part 31, as shown in FIG. 6, opens when the telephone pole is inclined sideways, and serves as a pedestal to prevent further inclination of the telephone pole. For example, it operates when the telephone pole 10 passes in the lateral direction due to a severe earthquake or typhoon.

The fall prevention part 31 is installed at the periphery of the part exposed to the ground of the hollow supporter 19. To this end, an upper hinge 19a and a fixed hinge 19d are installed on the outer peripheral surface of the upper end of the hollow supporter 19. The upper hinge (19a) and the fixed hinge (19d) are spaced apart from each other up and down, and support the rotating cover (31a) and the support rod (31f) so as to be rotatable. Four of the upper hinges 19a and the fixed hinges 19d are equiangularly arranged in the circumferential direction of the hollow supporter 19.

The fall prevention part 31 includes a support rod 31f, a ground block 31g, and a rotation cover 31a.

The support rod (31f), the upper end is linked to the fixing hinge (19d) with a connection pin (19e), it is rotatable around the connection pin (19e). The support rod 31f is subjected to the action of gravity, and is perpendicular to the ground when the telephone pole is erected vertically, and is widened from the hollow supporter 19 when the telephone pole is inclined as shown in FIG. 6.

The ground block 31g is an arc-shaped member fixed to the lower end of the support rod 31f, and when the support rod 31f is open, it contacts the ground and receives a support force from the ground. The ground block 31g is spaced apart from the ground when the pole 10 is vertical, but gradually approaches the ground as the support rod 31f opens, and is finally grounded to the ground. It goes without saying that it is possible to stably support and support the support rod 31f by applying the ground block 31g. Without the ground block 31g, the support rod 31f would penetrate the ground.

The rotating cover 31a serves to cover and protect the support rod 31f and the ground block 31g, and the upper end is hingedly connected to the hollow supporter and moves together with the support rod. That is, when the support rod 31f is opened, it is opened together.

A cover hinge 31b connected to an upper hinge 19a and a connection pin 19c is provided at the upper end of the rotating cover 31a. In addition, a space portion 31c is provided in the rotation cover 31a. The space part 31c accommodates the fixed hinge 19d, the support rod 31f, and the ground block 31g.

6 is a view showing a state in which the telephone pole 10 is inclined. As shown, as the telegraph pole 10 is inclined, the bending portion 21e of the standing pipe 21 is elastically deformed and primarily responds to the inclination of the telegraph pole. In fact, if there is no physical change in perception, and only the telephone pole 10 is shaken back and forth, left and right, the telephone pole 10 is automatically restored to the vertical position after the lateral load applied to the pole 10 disappears. This is because the standing pipe 21 has elastic restoration properties.

In addition, the support rod 31f is receiving a support force from the ground G through the ground block 31g in a state that is open in the direction of the arrow k. Since the support rod 31f is supporting the telephone pole 10 in a state supported on the ground, it is possible to block the transmission of the telephone pole 10 once.

In the above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical idea of the present invention.
