Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electrical switchboard, and more particularly, to an electrical switchboard having a power generating and cleaning function for automatically generating solar electricity through sunlight and cleaning the solar panel with developed electrical energy.

In general, the switchboard is an electrical equipment for securely supplying a relatively high electric power, and a box-shaped switchboard is installed at a specific position on the ground in a state of being disconnected from the outside, such as a concrete structure It is installed on the base. In addition, distribution panels are installed to supply power to collective electricity demand such as buildings, apartment complexes, and factories.

Such switchboards are mostly made of steel and are made of closed enclosures with doors for maintenance on one side. Inside the switchboard are transformers that generate high heat, current transformers, breakers, breakers, operation power breakers, fuses Various electric devices for power distribution of the holder and the like are provided.

Since the internal temperature of the switchboard is relatively higher than the external temperature due to geothermal heat as well as the heat discharged from the device itself, when there is an abrupt temperature difference between the inside and the outside of the switchboard, . Condensation phenomenon leads to corrosion of the line, which causes problems such as maintenance cost and shortage.

And since the electric devices generating high heat are built in, the internal temperature rises. Furthermore, the switchboard is mainly installed in the outdoors, and the internal temperature of the enclosure made of steel is directly received by the solar heat. Excessive temperature rise in the switchboard lowers the operation efficiency and function of various parts and electric devices, and furthermore, it is difficult to maintain due to high temperature, short circuit, etc. Particularly, Thereby shortening the life span.

Therefore, an air inlet hole is formed in the lower portion of the cabinet of the switchboard to cool the inside of the cabinet by introducing the outside air into the cabinet, and an exhaust port is formed at the upper portion of the cabinet so as to discharge the high- .

However, since the heat dissipation structure of such an ASSEMBLY relies on the heat exchange due to the temperature difference between the inside air and the outside air of the ASSEMBLY and the natural convection phenomenon that the hot air rises and the cold air descends, the thermal efficiency is very low, I can not lower it. As a result, problems such as deterioration, failure, short circuit, and shortened life span of the built-in electric device can not be solved. In summer, fire in the switchboard often occurs.

For this purpose, a separate blower is installed in the switchboard to forcibly discharge the high-temperature heat to the outside, but there is a disadvantage that extra power is consumed for driving the blower.

Accordingly, in order to overcome such disadvantages, Korean Utility Model Application No. 20-2009-0001665 (hereinafter referred to as "Prior Art Document 1") discloses an air conditioner in which, when the blower for driving the internal temperature is discharged by forcibly discharging the high- It is possible to use the stored power by storing the power generated from the solar panel, and to use the stored power when necessary such as at night, and by detecting the internal temperature, There is disclosed a heat dissipating device for a distribution board using a solar cell that can control a blower to be driven or stopped and to efficiently operate a heat dissipating function.

However, since the solar panel disclosed in the prior art document 1 is formed so as to be limited to the upper surface of the blower assembly locally provided on the upper surface of the housing, the solar light incident area is too small and the generated power is relatively low There is a disadvantage that sufficient power can not be supplied to drive the blower.

Since the amount of generated power depends on the amount of light incident on the solar panel, the amount of generated power is significantly reduced even when the solar panel is contaminated. Therefore, although the surface of the solar panel has to be cleaned periodically, the prior art reference 1 has a disadvantage that the amount of power generated by the solar panel is inevitably lowered because there is no cleaning means for cleaning the solar panel, There is another disadvantage that a lot of manpower must be mobilized when cleaning the surface of the solar panel by using a separate workforce.

A detailed description of the heat dissipating device of the power distribution board using the solar cell as described above is described in the following prior art documents, and therefore, a detailed description thereof will be omitted.

2 to 4, a cover unit for covering the solar panel 200 is provided on the base frame 220 on the upper part of the cleaning bar 300 .

The cover means includes a pair of fixed caps 350 which are fixed on the upper surface of the base frame 220 on the upper portion of the cleaning bar 300 so as to face each other and a rotary shaft And the other end is fixed to the cleaning bar 300 while the other end of the cleaning bar 300 is being wound around the rotation axis 330. The cleaning bar 300 is rotated by the rotation of the cleaning bar 300, And covers the cover member 320.

A fixed shaft 351 protrudes from a surface of each of the fixed caps 350 provided on the base frame 220. The fixed shaft 351 is inserted and coupled to both ends of the rotating shaft 330 The rotary shaft 330 is rotated in a state of being engaged with the fixed shaft 351 of both the fixed caps 350. The fixed shaft 351 is provided with a cutout portion 352 which can be engaged by inserting one end of the laterally-wound spring 340 in the axial direction of the fixed shaft 351, The spring 350 having one end connected to the spring 352 is fixed and fixed to the fixed shaft 351.

The rotation shaft 330 between the both fixing caps 350 is provided as a hollow tube and the fixing shaft 351 of the fixing cap 350 is inserted into both ends of the rotation shaft 330. The fixing shaft 351 As shown in Fig. In addition to the fixed cap 350 and the spring 350 to be described later, the receiving portion 332 to which the fixed cap 350 is coupled is formed at both ends of the rotating shaft 330 in a shape corresponding to the fixed cap 350 . The rotation shaft 330 is provided with a fixing base 331 which is rotated together with the rotation shaft 330 and to which the other end of the spring 350 is fixed.

The cover member 320 is provided at an area that can completely cover the solar panel 200 and is provided with a fixing bar 321 at one end thereof drawn out from the rotary shaft 330, And the bar 300 is engaged and fixed to the moving body 360 to which the bar 300 is coupled and fixed. Therefore, the fixing bar 321 of the cover member 320 is pulled or retracted from the rotation shaft 330 by the movement of the moving body 360, thereby preventing the cover member 320 from being completely curled on the rotation axis 330 .

5, a spring 350 is disposed between the housing 332 of the rotary shaft 330 and the fixed cap 350, and the spring 350 is inserted into the recess 350 of the fixed cap 350, And the other end wound around the fixing portion 331 of the receiving portion 332 of the rotating shaft 330 is fixed. When the cover member 320 is pulled out from the rotation shaft 330, the spring 340 is compressed to provide the cover member 320 with a restoring force.

In particular, the winding spring 340 is formed by bending a bent portion 341 at its inner end, and at its outer end, a "⊂" -shaped fitting portion bent at the same curvature as that of the winding spring 340 342 are formed. The bent portion 341 of the spring 350 is inserted and fixed in the cutout portion 352 formed on the fixed shaft 351 of the fixed cap 350 and the fitting portion 342 is engaged with the cutout portion 352 of the rotation shaft 330 The spring 340 is wound and compressed when the rotation of the rotation shaft 330 (the cover member 320 is pulled out) by the fixing member 331 protruded toward the pouring portion 332, And serves as a restoring force for restoring the member 320 to its original state.

The operation of the cleaning means and the cover means as described above is as follows.

6, when the motor 390 is operated in a state where the cleaning bar 300 of the cleaning means is provided on the upper part of the solar panel 200, the screw shaft 370 is rotated forwardly on the bearing block 380, And the movable body 360 screwed to the screw shaft 370 is moved from the upper portion to the lower portion of the solar panel 200 by the forward rotation of the screw shaft 370 as shown in Fig.

Of course, the moving body 360 fitted to the guide shaft 371 is also moved in the same manner as the moving body 360 of the screw shaft 370, and the cleaning bar 300 provided between the both moving bodies 360 is also moved to both the moving bodies 360. [ .

Accordingly, the cleaning brush 310 provided on the lower surface of the cleaning bar 300 is washed while being in contact with the upper surface of the solar panel 200 by the movement of the cleaning bar 300 as described above.

At this time, the cover means is operated in conjunction with the movement of the cleaning bar 300 as described above.

That is, when the cleaning bar 300 descends, the cover member 320 fixed to the fixing bar 321 of the cleaning bar 300 is pulled as the cleaning bar 300 and is pulled out of the rotation shaft 330.

At this time, the rotation shaft 330 is rotated in the same direction as the cover member 320 to be drawn out, and the rotation of the rotation shaft 330 causes the winding spring 340 in the fixed cap 350 to be wound and compressed.

8, the cover member 320 taken out along the cleaning bar 300 may completely cover the solar panel 200, and in particular, the solar panel 200 can not be used after sunset The cover member 320 is fully drawn out to completely cover the solar panel 200, thereby preventing contamination of the solar panel 200 due to unnecessary exposure.

In this state, the upper surface of the solar cell panel 200 is entirely swept away in a state where the cleaning bar 300 is completely moved downward from the upper portion of the solar cell panel 200, And the cover member 320 covers the solar panel 200 in this state. Thus, the cleaned solar panel 200 can be safely protected from pollution sources.

Thereafter, when the motor 390 is operated in reverse, the screw shaft 370 is rotated in the opposite direction, and the two moving bodies 360 are moved upward from the lower part of the solar panel 200 to sweep the solar panel 200 again Cleaned.

At this time, the spring 350 compressed in the fixed cap 350 quickly reversely rotates the rotating shaft 330 by the restoring force that is unscrewed and the reverse rotation of the rotating shaft 330 causes the cover member 320 to rotate The cover member 320 is moved upward as the cleaning bar 300 moves to the upper portion of the solar panel 200 and is smoothly wound around the rotary shaft 330 and stored.

Thereafter, when the operation of the motor 390 is stopped, both the movement of the cleaning bar 300 and the winding operation of the cover member 320 wound on the rotary shaft 330 are all stopped.

The shroud 110 of the switchboard 100 having the solar panel 200 may be provided with shading means that is operated by rotating the door 130 in the housing 110.

As shown in FIG. 9, the switchboard 100 having the above-mentioned shading means is described as an example in which a door 130 having a single structure is provided on the housing 110 in a hinged manner. However, In this case, it is preferable that the shading means is provided to be interlocked with the outer door of the dual structure door.

The ventilation openings of some of the plurality of ventilation openings 111 may be provided with the ventilation openings 112 through which rainwater is drained by a drainage member 160, which will be described later.

A roof 120 covering the upper surface of the housing 110 is provided on the upper portion of the housing 110. The roof 120 is formed to have a larger diameter than the outer diameter of the housing 110, As shown in Fig. Accordingly, the rainwater is drained away from the enclosure 110 when raining by the roof 120, and the shade is formed around the enclosure 110 by covering the sunlight at the time of standing.

An entrance 113 is formed in the upper portion of the enclosure 110 between the roof 120 and the door 130 to receive the access door 140 by inserting the access door 140.

9, the awning means includes an awning member 140 provided so as to be able to move in and out of the entrance 113 of the enclosure 110. Such an awning member 140 is inserted into the entrance 113 And one end of the first end portion of the shielding member 140 is inserted into the housing 110 and the other end of the first end of the shielding member 140 protrudes outward from the housing 110.

In particular, the rear end of the sheath member 140 inserted in the housing 110 is connected to the housing 110 as a spring 145, which can be provided with a compression coil spring, A force is always applied to the inside of the housing 110 by the elastic force of the covering member 140.

A guide portion 141 is formed at the tip end of the flange member 140 so as to be bent downward and an outer surface of the guide roller 170 provided at the upper end of the door 130, And is guided by the cloud.

Therefore, the opening angle of the door 130 can be adjusted each time the guide roller 170 of the door 130 is inserted into the locking part 144 and locked.

Although not shown in the drawings of the present embodiment, the top surface of the awning member 140 is formed to have a "∧" -shaped cross section on both sides in a state of being viewed from the front so that rainwater flows to both sides of the awning member 140 It can also be done. In particular, at this time, it is preferable that the guiding structure of the guiding portion 141 and both side guiding structures of the side shield 140 are formed so that only the upper surface of the guide structure 140 is bent in a "? &Quot; shape while maintaining the structure and form of the above-

A guide rail 150 is provided on both sides of the inner side of the housing 110 into which the awning member 140 is inserted and the guide rails 140 are inserted and guided at the center of both guide rails 150 The guide grooves 151 are formed to face each other.

A guide roller 170 is rotatably mounted on the upper end of the door 130, which is opened / closed in a hinged manner in the housing 110. The guide roller 170 protrudes outward from the front surface of the door 130 on the opposite side of the hinge 131 of the door 130, that is, on the upper end of one side of the door 130 where the locking device 132 is provided, And is firmly in contact with the inner surface of the guide portion 141 of the member 140.

The outer surface of the guide roller 170 rotates in contact with the guide portion 141. The outer surface of the guide roller 170 is provided with a magnetic body 171 so that the guide roller 170 is guided by the guide portion 141 The engaging portion 144, and the stopper 143 by a magnetic force. In particular, the magnetic body 171 may be formed of a permanent magnet made of a rubber material, and the magnetic body 171 made of rubber may be firmly fixed to the outer surface of the guide roller 170 by an attachment means such as an adhesive.

The guide roller 170 is fixed to the guide portion 141 of the sheath member 140 by the elastic force of the spring 145 that pulls the sheath member 140 into the housing 110 together with the magnetic body 171. Therefore, And in response to the operation of opening the door 130, the awning member 140 is pulled out from the housing 110 by interlocking with the guide roller 170.

A drain member 160 in the form of a plate is sloped downward toward the drain port 112 formed at the upper portion of the rear surface of the housing 110 and the drain member 160 is provided in the housing 110 below the awning member 140, The outer circumferential surface in contact with the inner circumferential surface of the housing 110 is welded and fixed to the inner circumferential surface of the housing 110 to firmly maintain the water tightness of the housing 110.

Therefore, when the awning member 140 is pulled back into the enclosure 110 after raising the awning member 140 in a rainy period, the rainwater on the awning member 140 falls to the upper surface of the water drainage member 160, (100) can be protected from the rainwater by being discharged to the outside through the drain port (112) of the cabinet (110).

When the door 130 is closed on the housing 110 of the switchboard 100, the guide roller 170 of the door 130 is guided by the guiding portion 141 And the other end thereof.

In this state, when the door lock mechanism 132 of the door 130 is released and the door 130 is opened and rotated by the housing 110 of the cabinet 100, the door 130 is rotated about the axis 131 of the hinge portion 131, So that the housing 110 is opened.

At this time, the guide roller 170 at the upper end of the door 130 is rotated in the state of being in surface contact with the guide portion 141 of the oblique member 140, rotated like the door 130, , The jaw member 140 is pulled out of the housing 110 and pulled out as shown in Fig.

That is, since the external force (rotational force) for rotating the door 130 is larger than the elastic force of the spring 145 restricting the inside of the housing 110, the spring 145 is pulled, The guide roller 170 of the door 130 that is pulled out of the housing 110 and pulls out the awning member 140 is attached to the guide portion 141 of the awning member 140 by a magnetic force, And moves along the guide portion 141 by the amount of rotation of the guide portion 130 while being rotated.

The guide roller 170 of the door 130 is moved along the guiding portion 141 of the covering member 140 and inserted into the guiding portion 144 bent and bent into the guiding portion 141, The door 130 is supported and fixed by the guide roller 170 engaged with the locking part 144 in a state where the door 130 is opened at a predetermined angle from the housing 110 as shown in FIG.

Therefore, by forming a plurality of the latching portions 144 in the guide portion 141, the opening angle of the door 130 to be opened can be adjusted at various angles.

The guide roller 170 of the door 130 rides over the locking portion 144 and is guided by the guide portion 141 by the external force (rotational force) of the door 130, And is stopped by the bent stopper 143 at the end of the guide portion 141 to stop the movement.

11, the door 130 is opened in an obtuse angle range exceeding a right angle of 90 degrees from the housing 110 and the guide roller 170 is attached to the stopper 143 by a magnetic force The door 130 is not easily closed even when an external force due to wind or the like acts on the door 130, thereby making it possible to firmly maintain the opened state.

When the guide roller 170 of the door 130 is pulled out from the housing 110 by the guide roller 170 of the door 130 and the guide roller 170 is hooked on the stopper 143, 140 are maximally drawn out from the housing 110.

Therefore, since the entrance of the housing 110 opened by the shoehorn member 140 which is maximally drawn out from the housing 110 is obscured, it is possible not only to block the inflow of rainwater at the time of rainy weather but also to provide a wide shade at the standstill, It is possible to provide a safe and pleasant work environment to the workers even in the climatic conditions.

Thereafter, after the maintenance and maintenance of the switchboard 100 is completed, the operator rotates the door 130 in the above-described direction to close the door 130 to the housing 110 and lock the door 130 with the locking device 132.

In the process of closing the door 130 in the reverse direction, a compression force (restoring force) is generated in the spring 145 which has been pulled up most by the pulled-away shade member 140, 140 are pulled into the inside of the housing 110 and automatically drawn in.

The rainwater remaining in the shingling member 140 may fall into the enclosure 110 and the dropped rainwater may fall over the drainage member 160 sloped in the enclosure 110 below the shingling member 140, 110 to the outside of the housing 110 through the drain port 112 of the housing 110.

Therefore, even if a part of the rainwater falls into the enclosure 110 according to the use of the shingling member 140, the rainwater can not flow into the electrical equipment inside the enclosure 110, And is discharged to the outside through the drain hole 112, so that the awning member 140 can be safely used in a rainy day.
