Description

Hinged underground waterproof device of hinged type

The present invention relates to a hinged underground waterproof box device, in detail, electrical distribution panel, fractional distribution box, street lamp control panel, manhole pump control panel, rectifier base, distribution panel or water and sewage measurement panel, traffic signal control panel, communication relay base, optical cable distribution panel, cctv Control panel, TM / TC panel, remote monitoring control panel, etc. are built in waterproof manhole for easy maintenance, low manufacturing cost, hinged underground with no external power, waterproof and drainage It is to provide a waterproof box device.

The electric and communication boxes installed on the ground are equipped with street light control boxes and traffic signal control panels. With the development of IT, numerous electric and communication boxes such as optical cable distribution boxes, communication relay bases, etc. have been installed outdoors to improve the urban aesthetics. Injury is caused by traffic accidents and electric shock accidents. In addition, the electrical and communication box has a number of problems, such as high-end expensive equipment is installed outdoors to operate in a harsh external environment, excessive energy used, corrosion caused by external moisture occurs, shortening the life of the device.

In addition, the bicycle road is provided on the side of the road facing the sidewalk recently, the bicycle traffic is inconvenient due to the street lamp control panel, switchgear, traffic signal control panel, etc. installed on the side of the road, and accidents collide with the bicycle.

As the domestic technology for underground distribution box for the distribution and management of electricity as described above, if the distribution box installed in the ground is excellent, the distribution panel is lifted in the housing as a domestic patent No. 10-0816866 'inundation prevention and insulation Although there is a technology for 'type underground cable distribution box', there is no watertight solution for the distribution box in the malfunction of the rain sensor.

In addition, the Korean Patent Registration No. 10-0922869 'underground distribution box linked to the electric manhole' is installed in the ground distribution box, but the distribution box storage part and the manhole portion formed with a drain trench on the bottom, but also the distribution box for the flooding It is a technology that does not have a separate watertight plan other than the drain trench.

As another domestic technology, domestic patent registration No. 10-0947101 'underground electrical installation container system' has a buried box structure in which the side and the bottom of the front direction are sealed and the top is open; A moving part for moving the electrical equipment box installed on the inner floor to the outside of the buried box through the opening of the upper surface of the buried box, a control box having an interface for controlling the movement of the electric lying box by the moving part, and an upper open part It is a technology that consists of a cover that seals the sealing box, watertight means, or when the rainy season when the cover is open to prevent rainwater from entering the inside of the buried box, if the malfunction of the electrical equipment box system installed on the bottom of the inner top plate In this case, it is difficult to lift the electric box because the internal equipment cannot be repaired, and the motor or electric box that drives the hydraulic pump is not watertight, so it is flooded when there is a problem with the waterproof packing of the cover. Damage is foreseen.

In addition, there is a concern that the cable covering may be damaged when the backfill is installed after the installation of the buried box, and the upper part protrudes to the ground, which may cause traffic jams. It is difficult to construct.

Meanwhile, in the applicant's Korean Patent Registration No. 10-0978210, 'Distribution box underground lifting device', a watertight box and a watertight box selected from steel structures or synthetic resins on all side walls except for the upper part of the rectangular box and the buried box. And a grounding plate which is integrally attached to the outer bottom of the buried box through each floor inside the buried box, the top cover of the rectangular box provided on the top of the buried box, the waterproof manhole cover on the disc, and the bolt assembly below the top of the facility box Installed inside the buried box through the installed equipment box, the hydraulic cylinder which is the means of lifting and lowering the equipment box installed on the inner bottom of the buried box, the heat collecting pipe and the heat dissipation pipe penetrated between the inside and the outside of the buried box, and the line protection pipe assembled through the side wall of the buried box. The distribution box underground lifting device, which consists of the cable chain introduced at the bottom of the equipment box through the cable gland, is registered. The.

In addition, the applicant's application No. 10-0024191, 'Measuring, monitoring, and underground lifting device of switchgear' is integrally assembled with the watertight box part and the watertight box part upper edge where the rectangular side wall except the upper part is selected as the steel structure. Frame frame with fixed length guide bar guided to guide rail grooves assembled at regular intervals on both inner side walls of gas spring cylinder part assembled at the center of watertight box packing step and the bottom of watertight box 'The instrument is composed of a control panel unit which is attached to both sides of the enclosure frame frame part by a hinge is assembled to the watertight box top hatch part and the watertight box top hatch part assembled by the upper part and the housing frame frame part and bolts and nuts. 'Underground lifting and lowering device of the measurement remote monitoring and switchboard' has been applied for.

The method of raising and lowering using the hydraulic and electrical equipment of the underground mines as described above increases the manufacturing cost by the configuration of the hydraulic and electrical equipment, and the method using the gas spring as the gas spring rises and falls vertically over the entire control panel weight. It is foreseeable that the length of the stroke will make the manufacturing cost of the gas spring uncomfortable, and if the material used to waterproof the cable loses its function, it will foresee considerable cost and time to repair the sidewalk and soil for replacement.
