Description

Technology Field

Background Technology

[0002] Road drains are formed on roads to discharge rainwater or wastewater into sewage treatment plants or rivers through underground sewer pipes. Generally, road drains are formed at the edges of the road, and when the road is separated into a carriageway and a sidewalk, they are installed adjacent to the curbstone forming the boundary between the carriageway and the sidewalk.

[0003] Road drains are typically covered with gratings to prevent water from flowing into them while ensuring that people, the wheels of transport vehicles, and contaminants do not fall in. Gratings are a grid-like structure in the shape of iron bars that prevents foreign objects larger than a certain size from flowing into the road drain, and are also designed to withstand a certain load, allowing pedestrians or vehicles to move safely without falling into the road drain.

[0004] Depending on the size of the drainage holes in the grating, cigarette butts or other small foreign objects may enter, and these foreign objects entering the road drainage system are inevitably discharged directly into the river; this can cause water pollution that destroys the river environment.

[0005] Furthermore, depending on the size of the grating's drainage holes, debris or fallen leaves exceeding a certain size may become clogged and accumulate on top of the grating instead of flowing into the road drains. This not only causes significant inconvenience to pedestrians and vehicles but also increases the risk of accidents due to the obstructed view of the ground below.

[0006] Particularly during the summer rainy season or typhoons, when torrential downpours occur, debris and fallen leaves often block road drains, preventing rainwater from draining and causing flooding on the roads. Although local governments remove debris and leaves from road drains in advance to ensure proper drainage during heavy rainfall, administrative management of road drains faces difficulties due to the significant manpower required and continuous maintenance.

[0059] The motor (310) can generate rotational force for the conveyor belt section (100) to transport foreign matter forward and provide the generated rotational force to the motor pulley (320).

[0060] The motor pulley (320) is coupled to one end of the motor (310) and can be rotated according to the rotational force provided by the motor (310). The plate belt (150) has one end and the other end wound around the motor pulley (320) and the drive pulley (140), respectively, so that the drive pulley (140) can be rotated according to the rotation of the motor pulley (320). The front rotation axis (130) rotates according to the rotation of the drive pulley (140), and the belt (110) can be rotated according to the rotation of the front rotation axis (130).

[0061] The control unit (410) can control the drive unit (300). When the control unit (410) receives a rainwater detection signal from the detection unit (420), it can control the drive unit (300) to provide rotational force to the conveyor belt unit (100). Accordingly, the device (10) for automatically removing rainwater from a road drain according to the present invention can automatically rotate the belt (110) of the conveyor belt unit (100) when it rains to remove foreign matter accumulated on the belt (110).

[0062] The control unit (410) can receive operation control information from the communication unit (430). The control unit (410) can control the driving unit (300) based on the operation control information. Accordingly, the device (10) for automatically removing rainwater from a road drain according to the present invention can remotely rotate the belt (110) of the conveyor belt unit (100) when it rains to remove foreign matter accumulated on the belt (110).

[0063] The above operation control information may include at least one of drive instruction information instructing the rotation of the drive unit (300), drive time information instructing the rotation period of the drive unit (300), and drive stop information instructing the stop of the drive unit (300). When the control unit (410) receives the drive instruction information, it may control the drive unit (300) to provide rotational force to the conveyor belt unit (100). When the control unit (410) receives the drive time information, it may control the drive unit (300) to provide rotational force to the conveyor belt unit (100) for the period indicated by the drive time information. When the control unit (410) receives the drive stop information, it may control the drive unit (300) to stop.

[0064] The detection unit (420) can detect rainwater and output a rainwater detection signal to the control unit (410). The detection unit (420) may include at least one of an optical level switch, a water level control float switch, and a rainwater detection sensor.

[0065] The optical level switch includes an infrared light-emitting diode (LED) and a photosensitive receiver. Light emitted from the LED is transmitted to the lens at the top of the optical level switch. When liquid is immersed in the lens of the photoelectric level switch, the light is refracted by the liquid, and the photosensitive receiver may or may not receive a small amount of light. The optical level sensor and photosensitive receiver in an operating state can drive an internal alarm switch to activate an external alarm or control circuit. If there is no liquid, the light from the LED may be reflected directly from the lens to the photosensitive receiver. The optical level sensor can output a high voltage value or a low voltage value depending on whether the state is water or not. When the prism of the optical level sensor is in a liquid state, the optical level sensor can output a low voltage. When the prism of the optical level sensor is in the air, the level sensor can output a high voltage. Using this, the optical level switch can detect rainwater and output a rainwater detection signal to the control unit (410) based on the principle of operating the switch using the optical level sensor when the height at which rainwater is detected reaches a certain level.

[0066] A liquid level control float switch can consist of a magnetic spring switch, a reed switch, and a float. The float can detect the position of the liquid level by activating the magnetic spring switch when the level of the tested liquid moves up and down. The reed switch can operate by relying on two basic scientific principles: buoyancy and magnetism. Buoyancy raises the float (containing a magnet) along with the liquid, and magnetism can help open and close the reed switch. Since this product was introduced to the market, it has been significantly improved and advanced in terms of convenience and safety, and with reduced costs, the liquid level control float switch has the advantage of being very compact, simple, and easy to install in small locations.
