Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone pole fixture cleaning and cooling device,

The present invention relates to an installation cleaning and cooling apparatus for managing various installations installed in a telephone pole, and more particularly, to a system and a method for removing pollutants during installation of a fixture and reducing the temperature of the installation, And a cooling device.

Power generated by a power plant is transmitted to a substation in each region through transmission lines including large-scale transmission towers, and then transformed at various stages in a substation to be supplied to a customer in a nearby factory, building, or apartment.

One of the most common transmission methods for supplying power to consumers is to install the poles at necessary intervals and to support the cable wires on the poles. To connect a wire cable to a telephone pole, the insulator is fixed to the wire rods of various structures fixed to the upper end of the telephone pole, and the wire cable is connected to the insulator. At this time, wire cables are connected to each other through a jumper wire.

An insulator is an electric part installed between the high-voltage power cables, between the power cable and the pylon or between the power cable and the transmission / distribution equipment, for maintaining the electrical insulation, It is made of synthetic resin and wrinkles are formed on the other surface to improve the electrical insulation property.

In recent years, a polymer insulator having a relatively good insulation and mechanical characteristics, light weight, and easy processing and installation has been used more than a ceramic insulator. The polymer insulator is formed of a polymer as a main body, and has a plurality of polymer shoulders formed on the outer circumferential surface thereof, and has a clevis or mouth type coupling metal at both ends of the main body.

However, the polymer insulator can be destroyed at any moment due to excessive electrical and mechanical stress or by heat generated by a large power arc, and can be damaged due to changes in temperature through the summer and winter, pollutants in the air, , And may be easily deteriorated by an abnormal voltage caused by lightning or an outdrive.

On the other hand, the insulator gradually deteriorates the insulation function because foreign matter sticks to the surface of the insulator as the time after installation becomes long. Particularly when salt or dust begins to adhere to the surface, the moisture is very easily coated and the dielectric strength is greatly reduced.

If the electric insulation leaks due to a decrease in the dielectric strength, an electrical safety accident such as a power failure occurs, resulting in a great economic loss. As such, the contamination of the insulator is associated with major power outages or safety accidents, so regular or irregular cleaning and management of insulators is essential.

Conventional insulator cleaning has been carried out in such a manner that a worker rides up a staircase of a steel tower, or rides on a basket of a work boom, and injects wash water using a spray gun while approaching the insulator.

However, this type of manpower is very difficult and difficult in itself, and there is a problem that the risk of electric shock and fall is very high. For example, in the case of a double insulated insulator, it is difficult to wash two insulated insulators at the same time, so that a lot of time is consumed in the washing work. In addition, in the course of washing a series of insulated insulators, If the flashing phenomenon occurs due to the indirectly sprayed washing water or contaminated dust, it may be killed by the electric shock.

On the other hand, there is a transformer in addition to the above-mentioned bullet and insulator as described above. A transformer is a device for raising or lowering a voltage. A transformer, which is commonly seen in the vicinity, functions to distribute high voltage currents flowing through a power cable to the home.

However, the longer the transformer is used, the lower the internal insulation strength, the lower the insulation resistance due to deterioration, and the more likely it is to explode. Especially during a hot period, the temperature is higher up to the outside temperature and the probability of explosion becomes bigger. The explosion of the transformer, which is actually reported by the media, is caused by the overheating of the transformer.

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

Basically, the poles of the present invention can be cleaned by spraying cleaning water or cooling water to various fixtures installed on a telephone pole, for example, insulators or transformers. For example, it is possible to prevent the explosion of the transformer by injecting cooling water to the transformer during the hot period.

The washing and cooling apparatus of the present invention includes a spraying unit disposed close to the installation and spraying water toward the installation; A temperature sensor installed in the telephone main body for sensing a temperature around the telephone main body; A controller for controlling the supply of the water supplied from the outside to the sprayer, wherein the controller is configured to supply the water supplied from the outside to the sprayer, A pump for supplying the water passing through the cooler and the heater to the sprayer, and a control unit for controlling the cooler and the heater based on temperature information, connected to the temperature sensor.

FIG. 1 is a view for explaining a configuration of a device for cleaning and installing an electric pole fixture according to an embodiment of the present invention, and FIG. 2 is a sectional view showing the internal structure of the electric pole shown in FIG.

As shown in the figure, the apparatus for cleaning and installing a telephone pole fixture according to the present embodiment includes a water supply unit 30 embedded in a side of a telephone pole 10, first and second ejector units 40 and 40 mounted on a telephone pole 10, 50, an upper nozzle unit 21, a temperature sensor 63, and a communication module 61.

The washing and cooling device of the present embodiment as described above requires a telephone main body provided with an inner pipe 11 therein.

2, the electric wire rod 10 includes a hollow main body 10a having a through hole 10b with a predetermined inner diameter formed in the central shaft portion and an inner pipe 11 fixed to the through hole 10b . The hollow main body 10a is made of concrete in the same manner as a general telephone pole, and is supported on a ground G by being vertically erected.

The inner pipe 11 is a hollow pipe extending along the longitudinal direction of the main body 10 in close contact with the inner circumferential surface of the through passage 10b and the upper and lower end portions thereof are exposed to the upper and lower portions of the hollow main body 10a.

A female screw portion 11b is formed on the inner peripheral surface of the lower end portion of the inner pipe 11 and is sealed by the lower end cap 12. [ The lower end cap 12 has a male threaded portion 12a as a stopper for closing the inner pipe. And the lower end of the inner pipe 11 is sealed by engaging the male screw portion 12a with the female screw portion 11b.

Also, a female screw portion 11b is formed on the inner peripheral surface of the upper end portion of the inner pipe 11 as well. The upper end of the inner pipe is closed and closed by the upper end cap (13). The upper cap 13 is a cap having a male threaded portion 13a. The upper end of the inner pipe 11 is clogged by screwing the male screw portion 13a to the female screw portion 11b. The inner pipe 11 may be a metal pipe or a synthetic resin pipe.

In addition, an upper nozzle unit 21 is mounted on the upper end of the main body 10. The upper nozzle portion 21 has an introduction tube 21a whose lower end portion passes downward through the upper cap 13 and communicates with the vertical passage 11a, a head 21b connected to the upper end portion of the introduction tube 21a, And a plurality of nozzles 21c disposed on the periphery of the nozzles 21b.

The upper nozzle unit 21 serves to inject pressurized water into the inside of the vertical passage 11a. That is, a part of the water injected into the vertical passage 11a is injected in four directions by the nozzle 21c after passing through the inlet pipe 21a and the head 21b in order. Sprayed water is used to wash contaminants accumulated in facilities supported by telephone poles.

In addition, an injection tube 36 is installed at the lower end of the inner pipe 11. The injection tube 36 is a hollow pipe for leading the water pumped in the water supply portion 30 into the interior of the inner pipe 11.

Further, a plurality of branch tubes 15 are located on the side of the inner pipe 11. The branch tube 15 is a part of a jetting portion to be described later, one end of which is horizontally connected to the inner pipe 11, and the other end is clogged with the side cap 14. [ The inner pipe 11 and the branch tube 15 communicate with each other so that the water supplied into the inner pipe 11 is also filled into the branch tube 15. [

A female thread (not shown) is formed on the inner circumferential surface of the branch tube 15, and a male screw portion 14a is provided on the side cap 14. [ The sealing state of the branch tube 15 is maintained by screwing the side cap 14 to the branch tube 15. When the side cap 14 is detached, it means that the branch tube 15 is opened and water injected into the inner pipe 11 is horizontally ejected.

Basically, all the branch tubes 15 are sealed by the side caps 14. The side cap is removed to connect the injection section to the branch tube. The branch tube 15 at the point where the jetting section is not provided stands by with the side cap 14 closed.

The water supply unit 30 is embedded in the side of the telephone main body 10 and mechanically supplies water to the inner pipe 11 by heating or cooling the water supplied through the water pipe 31a.

The water supply unit 30 includes a box-like container 30a buried in the bottom of the paper G, a cooler 32 and a heater 33 installed inside the container 30a, first and second pumps 32a and 32b, A control unit 34, and a communication unit 35.

First, the container 30a is a box-like case that can be opened to the ground through a check lid 37 taking the form of a manhole cover. Normally, the inspection lid 37 is closed to completely block the inner space of the container 30a.

The cooler 32 is a conventional mechanical cooling device that cools water supplied through the water pipe 31a. The water cooled by the cooler 32 is pumped by the first pump 32a and pressured into the inner pipe 11 through the injection tube 36. [

The heater 33 has a configuration such as a gas boiler or an oil boiler, and heats the supplied water through the water supply pipe 31a. The water heated by the heater 33 is pumped through the second pump 33a. The pumped heated water is injected into the inner pipe 11 through the injection tube 36.

The cooler 32 and the heater 33 are controlled by the control unit 34. The cooling temperature and the heating temperature of the water are controlled by the control unit 34. [ In addition, the cooler 32 and the heater 33 selectively operate. The heater 33 does not operate when the cooler 32 operates and the cooler 32 does not operate when the heater 33 operates.

The communication unit 35 transmits the temperature information wirelessly connected to the communication module 61 to be described later and received from the communication module 61 to the control unit 34. The control unit 34 operates the cooler 32 to eject the coolant through the first and second sprayers 40 and 50 when the current temperature is higher than a set temperature, for example.

In addition, the communication module 61 is wirelessly connected to the portable terminal of the administrator. The manager can operate the water supply unit 30 by connecting to the control unit 34 through his / her portable terminal. The cooler 32 and the heater 33 can be operated.

1, a temperature sensor 63 and a communication module 61 are provided at the upper end of the main body 10. The temperature sensor 63 senses the temperature around the electric pole and transmits the detected temperature to the communication module 61. The communication module 61 transmits the temperature information received from the temperature sensor 63 to the communication unit 35 so that the control unit 34 performs appropriate operations.

The insulator 71 and the transformer 75 are fixed to the electric pole 10. The insulator 71 and the transformer 75 are objects to be cleaned and cooled as fixtures supported by the electric pole.

One end of the insulator 71 is supported on the main body 10 through the connection bracket 72 and the other end is connected to the power cable 73. The mounting manner of the insulator 71 is general. The transformer 75 is also supported on the pole 10 via suitable fastening means.

A first spray part (40) is installed below the insulator (71). The first jetting section 40 injects cooling water or heating water toward the insulator 71 and the connection bracket 72. For example, in order to clean the insulator 71, the hot water is sprayed or the coolant is sprayed to cool the insulator 71.

The first jetting section 40 includes a receiving body 41 fixed to be inclined upward by the receiving frame 47 and a plurality of nozzles 44 and a connector 46. The inclination angle &thetas; of the receiving body 41 with respect to the horizontal plane may be about 10 to 15 degrees.

The reason why the receiving body 41 is inclined is that the supplied water does not remain in the receiving body 41 but flows backward to be returned to the inner pipe 11. That is, after the injection of water is completed, the water remaining in the receiving body 41 is discharged to the outside of the receiving body 41.

Fig. 3 is a diagram showing the structure of the first jetting section 40 in more detail, and Fig. 4 is a perspective view of the first jetting section.

As shown, the first jetting section 40 includes a branch tube 15, a connector 46, a receiving body 41, and a nozzle 44.

The branch tube 15 is a horizontal pipe communicating with the inner pipe 11 as mentioned above. The connector 46 removes the side cap 14 that was sealing the branch tube 15 and connects the branch tube 15 and the receiving body 41 as an integral part thereof. To this end, male threads 46a are formed at both ends of the connector 46. [

The one male threaded portion 46a is screwed to the branch tube 15 and the other male threaded portion 46a is screwed to the inlet 41a of the receiving body 41. [ In addition, a through hole 46b is formed in the connector 46. [ The passageway (46b) is a passage for guiding the water inside the inner pipe (11) to the receiving body (41).

The receiving body 41 takes the form of a rod extending in the longitudinal direction and has an internal passage 41b therein. It goes without saying that water having passed through the connector 46 flows into the internal passage 41b. The shape of the receiving body 41 depends on the shape and size of the installation.

The nozzle 44 is disposed on the upper surface of the receiving body 41 and injects upwardly the water supplied through the internal passage 41b. The water jetted from the nozzle 44 reaches the insulator 71 and the connection bracket 72. [

If the water to be sprayed is heated water, it is possible to effectively remove foreign matter such as bird droppings adhering to the insulator 71 or the connection bracket 72. Further, if the cooling water is cooled, the overheated insulator 71 and the connection bracket 72 are cooled together. The cooling water serves both to clean the object and to cool it. Especially when cooling water is applied to the overheated insulator 71, explosion of the insulator can be prevented.

As shown in FIG. 4, a charging type battery 42 is incorporated in the receiving body 41. The rechargeable battery 42 is installed in a mounting space (not shown) provided in the receiving body 41 and outputs electric power to the outside. Reference numeral 41c denotes a door. The door 41c serves to open and close the mounting space.

A plurality of LED lamps 43 and a speaker 45 are disposed on the side of the receiving body 41. The LED lamp 43 receives electric power from the battery 42 and is turned on.

The operation of the LED lamp 43 can be controlled through the control unit 34 described above. The LED lamp 43 is turned on when the first jetting section 40 is operated. The manager can remotely determine whether the water dispenser 30 and the first sprayer 40 are operating through the fact that the LED lamp 43 is turned on.

The speaker 45 outputs sound when the first jetting section 40 is operated. That is, when the water is sprayed through the first sprayer 40, the sound is output to inform people who pass around the telephone pole.

Meanwhile, a second jetting unit 50 is installed below the transformer 75. The second jetting section 50 serves to inject cooling water or heated water pressurized into the inner pipe 11 into the transformer 75.

The basic structure of the second jetting part 50 is the same as that of the first jetting part 40, except that the shape of the receiving body 51 is different. The receiving body 51 of the second jetting section 50 takes the form of a disk.

FIG. 5 shows the second jetting section 50 separately.

As shown in the figure, the second jetting section 50 includes a branch tube 15, a connector 56, and a receiving body 51. The receiving body 51 takes the form of a disk and has a plurality of nozzles 55 on its upper surface. The nozzle 55 serves to jet the water flowing into the receiving body 51 through the branch tube 15 and the connector 56 to the transformer 75.

At both ends of the connector 56, a screw portion 56a is formed, and a through passage 56b is formed therein. The water of the inner pipe 11 can be injected upward through the nozzle 55 by connecting the receiving body 51 to the branch tube 15 through the connector 56. [

The receiving body 51 is supported through the receiving frame 57 and is inclined in the same manner as the receiving body 41 of the first jetting section 40. That is, it is inclined upward in the direction away from the telephone pole. The inclining angle of the receiving body 51 is the same as the receiving body 41 of the first jetting section.

The receiving body 51 is also equipped with a rechargeable battery 52 and a space (not shown) accommodating the battery 52 is also opened and closed by the door 51a. It goes without saying that the battery 52 can be replaced through the door 51a.

In addition, a plurality of LED lamps 54 and a speaker 53 are installed on the side of the receiving body 51. The LED lamp 54 and the speaker 53 are operated when the second jetting portion injects the water, as in the case of the first jetting portion.

The cooling water injected from the second jetting section (50) cleans and cools the transformer (75). In particular, during a hot period, the transformer is overheated and the risk of explosion increases. Therefore, the cooling water is frequently injected through the second injection part 50 to prevent the transformer 75 from overheating.

As a result, the electric wire fixture cleaning and cooling apparatus of the present invention as described above ejects cooling water or heating water toward an insulator or a transformer to remove contaminants contaminating the part, and in particular, So that the explosion accident can be prevented.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
