Description

[0001] DESCRIPTION [0002] The present invention relates to a water-

More particularly, the present invention relates to an installation structure of a water tank and an electric distribution board, and more particularly, And an installation structure of the water distribution board and the switchboard that can prevent breakage of the components installed inside the switchboard and disconnection of the electric wires.

Generally, in collective electric power demand sites such as schools, buildings, apartment complexes, factories, etc., water power distribution devices are installed which receive high voltage power from a substation and transform them to low voltage in order to obtain power required by each.

The water power distribution system can be divided into the water front which receives extra high voltage, the front side which transforms the special high pressure to low pressure and the switchboard (or the distribution board) that distributes the lowered voltage to each accommodation place such as apartment, (LBS), which serves as the inlet of the power transformer, a power fuse (PF), which is a fuse for short-circuit protection of special high-voltage equipment, a transformer (MOF), which transforms the extra- A vacuum breaker (VCB) that cuts off the voltage when an abnormality such as a short circuit is installed inside the water front frame and is installed so as not to be disturbed by the disturbance.

This water power transformer is composed of a large transformer, a load break switch (LBS), a power fuse (PF), a meter transformer (MOF), a vacuum breaker (VCB) In consideration of safety, a sufficient space is provided between the devices in the front panel. Therefore, a wide installation space is required to install the water power supply device including the water front panel. Therefore, in consideration of safety, In the case where vibration such as an earthquake or the like that totally flows the water-front frame is applied even if the respective components are installed apart from each other, the water-front frame 100 can be largely moved left and right as shown in FIG. 1, Since the brackets and the like provided with the components by the flow of the first frame flow together and are deformed, the structures can not be normally fixed to the bracket, Or it may cause a short circuit or the like, there is a problem that severely can cause significant damage, such as a power failure or fire.

In order to solve such a problem, as shown in FIG. 2, there is a case in which the vibration-proof rubber is installed inside to fix the water-front frame. This is because the vibration- So that the vibration of the inner frame is absorbed by the vibration-proof rubber.

However, the seismic oscillation is largely composed of a P wave (primary wave) and a S wave (secondary wave). The P wave acts in the horizontal direction due to the elastic compression and expansion of the medium particles, and the S wave propagates in the propagation direction And the shape of the medium is changed by vibrating the medium in the direction perpendicular to the direction (vertical direction). The vibration-proof rubber has a limitation in its flow width in canceling (absorbing) the vibration P in the horizontal direction.

In addition, there is a fear that the inner frame installed inside the outer frame collides with the outer frame, resulting in an impact, and the damage to the structures installed in the inner frame is increased.

In addition, since the frame is flowed even in a small vibration, the vibration-proof rubber is driven by an external force generated by an operator or the like (force acting by an operator pushing or leaning during maintenance) There is a problem that the structural stability is not secured.

Therefore, it is required to develop the installation structure of the power switchboard which can guarantee the reliability of the water front and the power distribution board, because the water front and the switchboard are not easily deformed or distorted against vibration such as earthquake.

The pair of guide rails 20A and 20B are spaced apart from each other by a predetermined distance so that a pair of fixing brackets 24 protrude downward. Each of the fixing brackets 24 is provided with a second roller R2 do.

At this time, the second roller R2 is installed to rotate in a direction perpendicular to the first roller R1 installed on the bottom surface of the main body 10 and is slidably inserted into the guide groove H of the second rail unit 30 Lt; / RTI >

On the other hand, bolt coupling portions 25 are provided at both ends of the pair of guide rails 20A and 20B, and through-holes 11A formed in the lower panel 11 of the main body 10 by the bolt coupling portions 25 And a nut (not shown) is fastened to a bolt (not shown) provided through the through hole (not shown).

At both ends of the pair of guide rails 20A and 20B, a long hole 26 is formed along the length of each of the guide rails 20A and 20B. A buffer member 40, which will be described later, is inserted into the guide groove H, It is possible to appropriately adjust the position thereof in the longitudinal direction so that the range in which the sliding operation can be freely performed without interference of the buffer member 40 can be appropriately adjusted.

As shown in Fig. 7, the second rail unit 30 provided at the lower portion of the first rail unit 20 and having a length in the direction intersecting the first rail unit 20 has a " A pair of left and right guide rails 30A and 30B formed with guide grooves H are spaced apart from each other by a predetermined distance so as to be symmetrical to each other.

Both ends of the pair of guide rails 30A and 30B as in the first rail unit 20 are provided with bolt coupling portions 31 for fixing the foundation concrete to the foundation concrete, (32) are formed along the length.

8, the second roller unit R2 of the first rail unit 20 is slidable in the guide groove H, Respectively.

8, the guide rails 20A, 20B, 30A, and 30B of the first and second rail units 30 may be provided with separate elastic springs or the like, The first and second rollers R1 and R2 are returned to their initial positions (or center, middle) by their own weight, and then stably supported and held together.

As shown in Figs. 9 (a) and 9 (b), on the basis of the initial positions of the first and second rollers R1 and R2, a gentle "V When the first and second rollers R1 and R2 are positioned at the center (lowest point) of the inclined surface A, the bottom surface of the main body 10 is inclined to the first rail unit 20 and the bottom surface of the first rail unit 20 is held in contact with the upper surface of the second rail unit 30 and is stably supported with respect to each other.

When the main body 10 and the first and second rail units 20 and 30 are positioned at the initial position (or center, middle), the main body 10 and the first and second rail units 20, 30) are held in contact with each other to maintain a state in which they are held in contact with each other. Thus, an earthquake with a low degree of magnitude (a magnitude of 2 or less) The water supply system and the power distribution board are not easily operated by the sliding operation of the water supply panel and the power distribution board.

In the case where an earthquake vibration occurs at a degree of severity (a magnitude of 3 to 4 or more) that is likely to cause property damage, a large force acts in the horizontal direction relatively to the fixing force by the weight of the main body 10, The first and second rollers R1 and R2 of the one-rail unit 20 are slid along the inclined surface A of the guide groove H and as the sliding operation progresses, The spacing G is formed while the bottom surface of the main body 10 and the top surface of the first rail unit 20 or the bottom surface of the first rail unit 20 and the top surface of the second rail unit 30 are spaced apart, As a result, the horizontal sliding operation is performed smoothly.

The cushioning members are provided on both sides of the guide grooves H of the guide rails 20A, 20B, 30A and 30B of the first and second rail units 20 so as to absorb an impact caused by the sliding movement, 10A and 10B, a through hole 41A is formed at one end thereof and is inserted into the guide groove H to be fixed by a fastening member. Upper and lower cutouts 42 and 43 are formed integrally with the fixing portion 41 and have a length and are alternately cut at upper and lower surfaces at regular intervals and elastically contracted by an external force ).

In the present invention as described above, when the pressing force acts on the free end of the buffer member 40 by the upper and lower incised portions 42 and 43, it can be relatively easily and slightly contracted. When the sliding operation is performed, the first or second roller (R1, R2) pushes the free end of the buffer member (40) and the sliding operation proceeds, thereby absorbing the sudden shock due to the sliding operation and continuing the sliding operation A large amount of shrinkage occurs.

That is, the shock absorbing member 40 according to the present invention functions to prevent an impact from being generated due to a sudden sliding operation, and at the same time to secure an appropriate sliding distance in response to vibration.

As shown in FIGS. 11 and 12, when the water front or the switchboard is fixed to the foundation concrete or the like by the installation structure of the water front and the switchgear frame of the present invention as described above, The first rail unit 30 and the first rail unit 20 are slid in an appropriate direction and the flow of the water front panel and the switchboard frame disposed thereon is reduced by this operation, It is prevented from being broken.

After the sliding is caused by the vibration, the first and second rollers R1 and R2 are moved to the relative low point along the inclined surface A of the guide groove H by the self weight acting on the main body 10 When the first and second rollers R1 and R2 reach the relative low point of the guide groove H along the inclined surface A, the bottom surface of the main body 10 and the bottom surface of the first rail unit 20 and the bottom surface of the first rail unit 20 and the upper surface of the second rail unit 30 are brought into contact with each other and are stably fixed in position without sliding.

13, the first and second rail units 20 and 30 may be mounted on the bottom surface of each main body 10 even in such a case that a plurality of main bodies 10 are connected in a single row, The plurality of main bodies 10 may be interlocked and slidably operated by connecting the adjacent main bodies 10 by using separate connection brackets (not shown) And the switchboard.

In addition, as in the prior art, an inner frame is added to the water tank and the cabinet to provide a vibration proof rubber between the outer frame and the inner frame so as to flow in response to the earthquake vibration acting in the vertical direction. As a result, The earthquake vibration in the horizontal direction is canceled by using the first and second rail units 20 and 30 and the earthquake vibration in the vertical direction is absorbed through the vibration insulating rubber.

The present invention can relatively reduce the swing of the main body installed in the upper part thereof, that is, the water front and the distribution board, by sliding operation corresponding to the vibration of a certain degree or more, And safety accidents such as power outage and fire which are caused by breakage of water front and the switchboard by seismic vibration are greatly reduced.
