Description

Smart seismic device of distribution panel, solar connection panel, motor control panel}

The present invention relates to a smart seismic device for a distribution panel, a solar connection panel, and a motor control panel for preventing damage due to earthquake vibration.

In recent years, as the frequency of earthquakes increases due to changes in the natural environment, seismic protection equipment has to be installed over a certain scale.

In particular, facilities that use electricity, such as distribution boards, solar connection boards, motor control boards, etc., have many problems, such as when electricity is cut off due to an earthquake, the operation of the facility is stopped, and electric shocks occur. do.

In order to solve this problem, the "seismic structure" of Korean Patent Registration No. 10-2057536 (announced on December 20, 2019) has been disclosed.

The conventional seismic structure is a seismic structure fixedly installed under a seismic target object, and includes a lower plate having an inner receiving space of a hollow portion; An upper plate having an upper plate supporting the seismic object, spaced apart from the lower plate, and including a support post protruding toward an open surface by the hollow portion at a center thereof; And an elastic member installed on a lower surface of the support post, a side surface of the support post, and a lower surface of the upper plate corresponding to the outer periphery of the support post, and elastically supporting between the lower plate and the upper plate.

In the conventional seismic structure of this configuration, elastic members are installed on the lower surface, side surfaces, and outer edges of the support post to perform seismic resistance in response to vibrations occurring in various directions.

However, because the conventional seismic structure supports the seismic target object only with the elastic member, the elastic member easily swings even with small vibrations, and fatigue accumulates in the elastic member and is easily damaged, and it performs seismic resistance only by the elastic force of the elastic member, which is a spring. When a relatively large vibration occurs, the seismic structure is easily detached from the elastic member and can be buffered while easily moving up and down, left and right, but there is a problem in that it is difficult to buffer because there is a limitation on the behavior in the front and rear directions.

In addition, since the elastic members are installed in all directions, there is a problem in that manufacturing is difficult and manufacturing cost is increased.

In addition, there is a problem in that it is difficult to take measures according to the occurrence of vibration because it is difficult to grasp the vibration acting on the seismic structure from the outside.

The present invention was conceived to solve the above problems, and the problem to be solved by the present invention is to connect the upper plate member and the lower plate member by a flexible steel wire, so that the X-axis, Y-axis, and Z-axis directions within a preset range By ensuring the free movement of the ship, it is possible to perform seismic resistance in response to vibrations occurring in various directions, and the flexible steel wire firmly supports the upper plate member and the lower plate member to prevent separation of the enclosure. Its purpose is to provide a smart seismic device for optical connection panels and motor control panels.

In addition, vibrations that are relatively smaller than earthquakes are buffered by the flexible steel wire and the fatigue buffer member to reduce fatigue due to frequent oscillations of the seismic spring, thereby minimizing damage to the seismic spring, and reducing the manufacturing cost with a relatively simple structure. It is an object of the present invention to provide a smart seismic device of a distribution panel, a solar connection panel, and a motor control panel that can improve earthquake resistance by effectively buffering vibration by the elastic force of the earthquake-resistant spring, fatigue buffer member, and bending direction guide ball.

The flexible steel wire may include a screw portion formed at one end to be screwed to one of the upper plate member and the lower plate member, and a straddling head portion having a circumference larger than the thickness of the flexible steel wire so as to span the other. .

According to the present invention, since the upper plate member and the lower plate member are connected by a flexible steel wire and can move freely in the X-axis, Y-axis, and Z-axis directions within a preset range, they effectively respond to vibrations occurring in various directions.

The flexible steel wire 130 may connect the lower plate member 120 and the upper plate member 110 to freely move.

The flexible steel wire 130 can connect the lower plate member 120 and the upper plate member 110 in a spaced state, and the flexible steel wire 130 is flexible according to the behavior of the lower plate member 120 and the upper plate member 110 It is bent so as to guarantee a free movement, and at the same time, it is possible to prevent the lower plate member 120 and the upper plate member 110 from being separated from each other by limiting the range of motions of the lower plate member 120 and the upper plate member 110.

Here, the free motion means a motion in the X-axis, Y-axis, and Z-axis within a preset range, and the preset range may be set according to the length of the flexible steel wire 130.
