Description

Bridge drainage monitoring system

The present invention relates to a drainage monitoring system of a bridge, and more particularly, the rainwater flowing into a manhole installed in a bridge in rainy weather can be drained from a remote location by monitoring only the manhole that is not drained smoothly. It is about the drainage monitoring system of a bridge to prevent it.

In general, manholes installed in bridges are installed at regular intervals so that rainwater does not collect on the road in rainy weather and flows to the edge of the road while collecting rainwater that flows to the edge of the road. Rainwater introduced into the manhole is discharged through the drain pipe connected to the manhole.

For the management of the manhole, the work manager documents the information of each manhole individually, and finds a manhole that matches the data existing on the document one by one, and performs maintenance and cleaning, but with rainwater flowing into the manhole during rainy weather, The drainage pipe was clogged by garbage.

As described above, when the drain pipe is blocked, the rainwater does not flow into the manhole but is accumulated on the road. There is a problem such as an accident occurs.

As a prior art for solving the above problems, Korean Patent Publication No. 1771410 (announced on June 15, 2017) "Water level measurement system provided in the manhole cover" is a manhole cover located on the upper part of the manhole; A water level meter installed on a lower surface of the manhole cover and measuring water level information inside the manhole; And a communication module for transmitting the water level information measured by the water level gauge. And a power supply unit installed on the manhole cover and supplying power to the control unit, wherein the manhole cover is formed with one or a plurality of through holes, and the control unit and the power supply unit are coupled to a bracket provided with a fixing member. It is fixed to the through-hole of the lid, the fixing member is fixed by sliding to a position corresponding to the position of the through-hole along the rail formed in the bracket, is installed in the lower portion of the manhole cover in the inner direction of the manhole from the bottom of the manhole cover The control unit and the power supply unit is formed to be high, and further provided with a damage prevention ring to prevent damage to the control unit and the power supply unit provided on the lower surface of the manhole cover due to the collision with the ground, the control unit is a constant level information measured by the water gauge If it is above the figure, it transmits the final level information measured in the water level and By blocking the inside of the manhole to reduce the resistance value inside the control unit to prevent short-circuit and short-circuit, the power supply is installed on the manhole cover, the solar panel exposed to the outside, light introduced through the solar panel It includes a solar cell module for converting energy into electrical energy and a battery for storing the electrical energy converted from the solar cell module, the solar panel is installed in the through hole of the manhole cover is exposed to the outside, attached to the lower surface of the manhole cover And is inserted into the through hole and installed.

The prior art configured as described above is to supply electrical power to the control unit containing the water level meter, communication module by storing the electrical energy in the battery through the light introduced using the solar panel, the sunlight shines, such as rain or snowy day When it is not possible, the electric energy is not stored in the battery, but only the stored electricity is used, so a situation occurs in which the power is cut off.

That is, most of the manhole backflow occurs because rainwater is not properly discharged, and this phenomenon occurs most of the rainy days.

As described above, the prior art produces electrical energy by the solar panel, through which the measurement by the water level is not performed properly, as well as the communication module does not function properly.

In addition, the prior art constitutes a bracket to install the "water level measurement system provided in the manhole cover," the bracket is fixed to the manhole cover by a fixing member, the bracket is a sliding control unit installed on one side of the battery Combined, the control unit is configured to separate the control unit in the downward direction coupled to the sliding coupling to the bracket is very complicated installation process.

In addition, the prior art has a problem that the installation is difficult and of course a long time because the manhole cover must be removed after installation in order to install the "level measurement system provided in the manhole cover".

It is coupled to the horizontal bar of the locking piece 113 is fixed to the bolt 115 so as not to be separated in a state coupled to the horizontal bar.

The detector 100 installed in the steel grating 11 is installed at a position three quarters from the bottom of the manhole 10.

When rain falls while the detector 100 is installed in the steel grating 11, rainwater falling on the roads and sidewalks of the bridges is collected at the boundary between the roads and sidewalks, and the collected rainwater flows back into the manhole 10.

Rainwater flowing into the manhole 10 is drained to the drain pipe connected to the manhole 10, when more than the amount drained by the drain pipe, a certain amount of rain water is accumulated in the manhole 10, the water level rises, Ascending and positioned within a certain range is detected by the detection sensor 120 of the detector 100.

The detection sensor 120 detects rainwater, and the detection sensor 120 applies the data signal detecting the rainwater to the sub-receiver 200 through the communication unit 134.

When the data signal is applied from the detector 100 to the management server 400 through the sub receiver 200 and the main receiver 300 at a predetermined time interval as described above, the manager simply introduces a lot of rainwater into the manhole 10. It is possible to determine whether the water level is temporarily raised or the rain water is blocked by the waste introduced into the manhole 10 or the like.

In addition, the manager can prevent the rainwater from overflowing into the road by preventing the manhole 10, which is determined to be blocked by rubbish, by inserting a working group to manage the vehicle and preventing pedestrian traffic. .

As described above, the rainwater drainage state is checked by the detector 100 when the rain falls that the manager manages the state of the manhole 10 formed on the bridge with the naked eye, and quickly checks the state of the manhole 10. This makes it easy to manage and prevents wasted personnel from identifying manholes that normally drain smoothly.

In addition, since the state of the manhole 10 is quickly and accurately grasped, unnecessary cleaning or maintenance does not have to be carried out forcibly, so there is an advantage that unnecessary budgets can be prevented.

Although the detailed description of the present invention described above has been described with reference to the configuration of the present invention, the scope of protection of the present invention is not limited to the above configuration, and those skilled in the art will recognize the spirit and technology of the present invention. It will be understood that various modifications and changes can be made without departing from the scope.
