Description

Road Stand {STAND FOR STREET}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road stand, and more particularly, to a road stand that is vertically erected by a strut in which a lower part is embedded in the ground.

Generally, roads are equipped with stands such as street lamps, traffic lights or posts with signs. These stands are made of struts and are erected perpendicular to the ground as the lower end of the struts is buried in the ground. Therefore, the stand provides lighting or traffic signals or guides the destination while standing on the road.

These common stands are typically buried in the ground and the bottom of the strut is fixed to a concrete foundation whose surface is exposed to the ground. At this time, the stand is fixed integrally to the base object by the anchor bolt. Therefore, the stand is fixed to the ground in a solid state by the load of the base.

On the other hand, in recent years, heavy rains have occurred frequently in Korea due to climate change. These heavy rains can cause flooding, flooding of rivers, or flooding in lowlands. Thus, in recent years, road stands such as street lights, traffic lights or posts are often flooded with rainwater. In particular, road stands installed on riversides or lowlands are flooded with rainwater very often.

In this way, the stand submerged in the rainwater is stored in the rainwater by the submerged water level. However, these stands do not easily escape the stored rain even after several days of heavy rain. This is because these stands are drained only between the gaps of the base and the lower end of the landfill embedded in the ground. Therefore, in the case of a street light or a traffic light, there is a problem that cannot be used until the rain drops. In addition, in the case of a traffic light street lamp, an electric shock accident occurs due to the stored rain.

The present invention was created to solve the above-mentioned conventional problems, and an object of the present invention is to provide a stand for a road provided with a member which prevents the external rainwater from flowing into the landlord while draining the rainwater stored in the landlord. .

In particular, it is an object of the present invention to provide a road stand provided with a member for automatically draining rainwater by water pressure of rainwater.

On the other hand, the disk 30 may be provided with an outer protrusion 36 projecting outward as shown by the broken line. The outer protrusion 36 is an element which prevents the lower end of the disk 30 from entering the inside of the body frame 20 while being caught by the body frame 20. That is, the outer protrusion 36 is an element that plays the same role as the protrusion 26 of the body frame 20 described above.

Referring to Figures 3 and 4 attached to the operation of the road stand according to an embodiment of the present invention configured as described above are as follows.

Referring to FIG. 3, the disk 30 shields the drain hole 22 of the body frame 20 when rainwater is not stored in the pillar 10, that is, as shown in the usual case. At this time, the disk 30 tightly closes the drain hole 22 by the weight of the weight 39.

The disk 30 firmly closes the drain hole 22 so that water stored in the outside of the column 10 does not flow into the drain hole 22 when the column 10 is flooded. At this time, the disk 30 closes the drain hole 22 more firmly by the water pressure (WP) applied from the outside.

Meanwhile, the packings 40 seal around the flange 24 corresponding to the edge of the body frame 20 and the protrusions 26 of the body frame 20 corresponding to the inner edge of the disc 30. Therefore, the external rainwater does not flow further into the pillar 10. These packings 40 normally prevent the outside moisture from entering through the edge or the drain hole 22 of the body frame 20.

Referring to FIG. 4, the disk 30 opens the drain hole 22 of the body frame 20 when the support 10 is submerged and water drops are stored in the support 10. At this time, the disk 30 opens the drain hole 22 by the water pressure WP of rainwater stored in the support 10 as shown. The disk 30 smoothly drains rainwater as the inner surface 30a is streamlined. That is, the rainwater is discharged along the inner surface 30a of the disk 30 as the inner surface 30a of the disk 30 is streamlined. Therefore, the disk 30 is easily uniaxially rotated about the hinge HG by the rain and opens the drain hole 22.

When the disk 30 is opened by the water pressure WP and the water pressure WP is attenuated, the disk 30 returns to its original position while rotating back again about the hinge HG by the weight of the weight 39. Thus, the disk 30 firmly closes the drain hole 22 of the body frame 20 again.

In conclusion, the illustrated check valve is a kind of flap valve operated in one direction by the water pressure WP. These check valves may be provided in a single number in the support 10, as shown, alternatively may be provided in a plurality of support 10.
