Description

Ventilation and flood protection with manholes {The ventilation and flood protection with manholes}

The present invention relates to a manhole that can be installed power facilities and other facilities in the basement of the road or under the side of the sidewalk, ventilation power for the purpose of heat dissipation and humidity control by embedding power or other facilities inside the manhole acting as an underground storage. In addition, the ventilation is actively guided by the ventilation system, and the ventilation means is installed in the form of chimneys on the ground where the street lamps are erected and the top is used as a street lamp so that the administrative authority can easily obtain the permit for the administration. In addition, the lower part of the manhole has a water tank that collects the water that enters the manhole in a two-story structure, and calculates the amount of water that enters between the manhole cover and the pipeline so that water can be pumped out at regular intervals. Without it, the flooding of power and other equipment inside the manhole is prevented and fresh Since it is possible to ventilate the inside of the bolt with a single air, the present invention relates to a manhole having an effective ventilation device and an anti-immersion function.

With the rapid industrialization and urbanization of modern society, the demand for electricity has exploded, and facilities such as electric power facilities, such as Jeonju, have appeared in many places in the city, impairing the aesthetics of the city and preventing the efficient use of the urban space. It has been a threat to the safety of citizens.

In light of this, in recent years, underground construction has been underway to bury electric power facilities, but the electric wires are buried underground, but related electric power facilities are mostly installed on the ground because they cannot solve problems such as flooding, moisture, and temperature. .

By installing various electric power facilities on the ground, it is difficult for pedestrians to pass, and in the case of the mall, it is difficult to install electric power facilities in front of the mall because it is affected by the commercial area. In addition, the administrative office does not give private use permits on the sidewalks for civil complaints, pedestrian passes, and city aesthetics. Not only was the initial investment cost high, but the maintenance and repair costs were also high.

In order to solve the problem of the existing manhole, the manhole acting as underground storage is buried in the ground and the power and other facilities are stored inside the manhole, and the heat and moisture generated from the power and other facilities are solved. For this purpose, the air intake and exhaust vents on the ground were used to ventilate by natural convection.

However, the existing manhole is formed in the ground of the road or sidewalk because the intake and exhaust vents are formed in the ground of the road or sidewalk, so in the hot summer season, since the heat is introduced into the intake vent, it does not help heat dissipation of the power equipment and other equipment, thereby shortening the life of the power equipment or other equipment. There was a technical drawback that the drainage-related device must be provided because rainwater is introduced into the intake and exhaust vents as the water fills the ground when it rains a lot.

In Korea Utility Registration No. 443588, a method of burying a manhole in the ground and having a power distribution facility therein has been proposed. However, the conventional manhole adopts a method of dissipating heat from the distributor by dissipating heat from the distributor by dissipating heat from the distributor by installing a heat sink having good thermal conductivity on the top of the distributor for the purpose of heat dissipation of the distributor. As it is in contact with the ground, the heat sink does not radiate smoothly when the geothermal heat enters the ventilation hole in summer, which shortens the life of the distributor.The ventilation port is also in contact with the ground, so the distributor may be locked by the inflow of rain. There was this.

The present invention was developed in view of the conventional problems, and the purpose of the present invention is to provide a ventilation means for the purpose of heat dissipation and humidity control by installing electric power or other facilities inside a manhole serving as an underground storage, It actively induces ventilation, and in particular, the means of ventilation is similar to the existing street lamps, so that the top end can be used as a street lamp, so it is easy to receive permission from the administrative office, and a water tank is provided at the bottom of the manhole to provide water into the manhole. The silver flows into the bottom of the two-layer structure, so that the upper part of the power facility, etc., can be flooded or damp-proof, and the electric equipment and the motor pump that discharge water are discharged when the collected water is discharged at regular intervals. It prevents geothermal heat without harming the aesthetics of the road while preventing the inundation of the lower part of water and other facilities. The present invention provides a manhole having a ventilation device and an inundation prevention function that can ventilate the inside of the manhole with good air.

The present invention is to install underground power equipment and other equipment for connecting underground lines such as electric wires and communication lines, the manhole body to solve the problems of flooding, heat dissipation and moisture of power equipment and other equipment built into the manhole body An air inlet is formed through the upper side of one side of the air inlet, and the air inlet is connected to a post standing on the ground, and the inlet is formed with an inlet and an exhaust port respectively connected to the air inlet, so that the hot air inside the manhole is exhaust port. It is discharged to, and the fresh air excluding geothermal heat from the inlet is supplied to the inlet is characterized in that the heat dissipation of the power equipment and other equipment.

The manhole in the present invention is a box-shaped manhole that is embedded in the basement in a closed state of the power equipment including a transformer, a switch and a repeater,

An inlet formed on both sides through which the underground line including the electric line passes, an inlet formed on the rear side through which the air intake pipe passes, and an outlet formed above the inlet on the rear side where the exhaust pipe through which the air is discharged and installed And an inlet formed on the bottom surface, the top of which power equipment or communication equipment is installed therein; Located at the bottom of the upper end, the side is provided with a water level, the lower end is stored rainwater flowing into the inlet; A support for accommodating the suction pipe and the exhaust pipe and having a suction port and an exhaust port respectively connected to the suction pipe and the exhaust pipe at a distance of 1.5 m or more from the ground; A lid having a size capable of flowing in and out of the power facility formed at an upper portion of the upper end;

A manhole cover installed on the lid for the worker's access; And an inner manhole cover installed between the lower end and the upper end to drain rainwater collected at the lower end.

In the case of an electric line or a communication line for supplying electricity, power facilities such as transformers, switchgear and repeaters should be installed at certain distances to maintain a smooth supply and quality of electricity and communication. It had the disadvantage of taking up a lot of space. In the past, most of the ground space was installed in the free space of the sidewalk or the back road, but there were problems such as hurting the aesthetics, impeding passage, and creating a complaint against the installation.

According to the present invention, the manhole, which acts as an underground storage cell, is buried on the road or sidewalk, and the power and other facilities such as a transformer or a switchgear are built in the manhole so that it does not harm the aesthetics and does not need to be installed in a distant installation place. Can be installed in the manhole between each electric line and communication line buried there is an effect that the wiring work of the distributor and the wire and communication line is convenient and the construction cost is reduced.

The present invention has the advantage of extending the life of the device by effectively increasing the heat dissipation of the distribution machine by installing a blower fan in the mandrel inside the manhole by a forced supply and exhaust air supply method, in the form of a street lamp installed in the existing sidewalk By connecting the blower fan to the inside so that the intake and exhaust ports fall from the ground, the ground heat does not flow into the manhole, preventing the deterioration of heat dissipation due to the summer geothermal heat. There is an advantage that the inflow of the manhole is blocked.

Also, at the bottom of the manhole, a water tank was installed to store rainwater when it flowed into the manhole, and the watertight pump was pumped out once in a certain period by reinforcing the sealing of the manhole cover and the duct that may enter the water. Manholes can be installed to prevent immersion without installation. In particular, since the intake and exhaust of the ventilation means is far from the ground, the inflow of rainwater is extremely limited, so even if the water tank is pumped out once a year, the power equipment in the manhole has an advantage of preventing shortening of life due to inundation or moisture.
