[0019] Methods for detecting regional waterlogging on highways:

[0020] S1. First install the device on the outer wall of the railing;

[0021] S2. When a vehicle passes by, the accumulated water will splash into the water collecting block, and the floating ball will float up to drive the telescopic rod to move. The movement of the telescopic rod will block the infrared signal of the infrared sensor, so that the magnetic block will magnetically absorb the telescopic rod, so that the top rod, the first conductive block and the second conductive block will contact each other, and the electrical signal will be transmitted to the detection terminal to remind the staff that there is water accumulation on this section of the road;

[0022] S3, the telescopic rod, the first movable rod and the second movable rod will move simultaneously under the action of the telescopic rod, and the movement of the telescopic rod will discharge the accumulated water inside the water collecting block, thereby reducing the manual drainage process of the staff;

[0023] S4. When encountering heavy rain, a large amount of water will accumulate inside the water storage basin. The increased deadweight of the water storage basin will drive the pressing rod and the fixing ring to move downward and apply spring pressure. The first gear and the second gear will rotate under the action of the fixing ring to move the rack, the connecting rod and the protective cover downward. The protective cover will cover the outside of the water collecting block to protect the outer wall of the water collecting block to prevent a large number of false alarms in heavy rain.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By setting up a protective mechanism, when it rains, a large amount of water will accumulate inside the water storage basin, and the water inside the water storage basin will gradually flow out through the tiny holes inside it. When the outflow speed is lower than the accumulation speed, the water storage basin will drive the pressing rod and the fixing ring to move downward under the action of gravity, and the water storage basin will give spring pressure, and the fixing ring will drive the first gear and the second gear to rotate. The rotation of the second gear will give the rack thrust, and the rack will drive the connecting rod and the protective cover to move, so that the protective cover covers the outside of the water collection block to prevent rainwater from entering. When the rain stops, the water inside the water storage basin will gradually flow out through the tiny holes, and under the action of the spring, the protective cover will be driven back to its original position, thereby achieving the purpose of protecting the water collection block;

[0026] 2. By setting up an early warning mechanism, when a vehicle passes by on the road and there is a large amount of water on the road, the water will splash into the water collecting block under the impact of the tires, and the float will float up under the action of the water. The movement of the float will drive the telescopic rod to move until one end of the telescopic rod contacts the top of the top rod. At this time, the top rod will drive the first conductive block to contact the second conductive block under the action of the telescopic rod. The first conductive block will be electrically connected to the battery through the second conductive block, thereby transmitting the electrical signal to the detection terminal, thereby achieving the purpose of reminding the staff that there is water accumulation on this section of the road;

[0027] 3. By setting up a drainage mechanism, when the telescopic rod moves, the second movable rod on the outer wall of the telescopic rod will also move upward, and one end of the second movable rod will give a pulling force to one end of the first movable rod until the telescopic rod passes the infrared sensor. The infrared signal emitted by the infrared sensor will be blocked, and the magnetic block will be energized through the PLC controller. The magnetic block will attract the telescopic rod to move. The telescopic rod will drive the float, the telescopic rod, the first movable rod and the second movable rod to move upward under the action of suction. The telescopic rod will enter the interior of the water collecting block to make the accumulated water inside the water collecting block flow out, until the magnetic block is powered off at an interval under the action of the PLC controller. Then the telescopic rod and the float will return to their original positions under the action of gravity of the telescopic rod, the first movable rod and the second movable rod, thereby achieving the purpose of discharging the accumulated water inside the water collecting block.

[0053] Methods for detecting regional waterlogging on highways:

[0054] S1, first install the device on the outer wall of the railing 1;

[0055] S2. When a vehicle passes by, the accumulated water will splash into the water collecting block 501, and the floating ball 503 will float up to drive the telescopic rod 504 to move. The movement of the telescopic rod 504 will block the infrared signal of the infrared sensor 604, so that the magnetic block 605 will magnetically absorb the telescopic rod 504, so that the top rod 505, the first conductive block 506, and the second conductive block 507 will contact each other, and the electrical signal will be transmitted to the detection terminal to remind the staff that there is water accumulation on this section of the road;

[0056] S3, the telescopic rod 601, the first movable rod 602, and the second movable rod 603 will move simultaneously under the action of the telescopic rod 504, and the movement of the telescopic rod 601 will drain the accumulated water inside the water collecting block 501, thereby reducing the manual drainage process of the staff;

[0057] S4. When encountering heavy rain, a large amount of water will accumulate in the water storage basin 402. The increased weight of the water storage basin 402 will drive the pressing rod 401 and the fixing ring 403 to move downward and give pressure to the spring 409. The first gear 404 and the second gear 405 will rotate under the action of the fixing ring 403, so that the rack 406, the connecting rod 407 and the protective cover 410 will move downward. The protective cover 410 will cover the outside of the water collecting block 501 to protect the outer wall of the water collecting block 501 to prevent a large number of false alarms in heavy rain.

[0058] The working principle of the present invention is: when using this device, when a vehicle passes by on the road, if there is a large amount of water on the road surface, the accumulated water will splash into the water collecting block 501 under the impact of the tire, and the float 503 will float up under the action of the accumulated water. The movement of the float 503 will drive the telescopic rod 504 to move until one end of the telescopic rod 504 contacts the top of the top rod 505. At this time, the top rod 505 will drive the first conductive block 506 to contact the second conductive block 507 under the action of the telescopic rod 504. The first conductive block 506 will be electrically connected to the battery 508 through the second conductive block 507, thereby transmitting the electrical signal to the detection terminal, achieving the prompting effect. The staff has the purpose of accumulating water on this section of road, which improves work efficiency. When the telescopic rod 504 is active, the second active rod 603 on the outer wall of the telescopic rod 504 will also move upward, and one end of the second active rod 603 will give a pulling force to one end of the first active rod 602 until the telescopic rod 504 passes the infrared sensor 604. The infrared signal emitted by the infrared sensor 604 will be blocked, and the magnetic block 605 will be energized through the PLC controller. The magnetic block 605 will work to attract the telescopic rod 504 to move, and the telescopic rod 504 will drive the floating ball 503, the telescopic rod 601, the first active rod 602, and the second active rod 603 to move upward under the action of suction. When the telescopic rod 601 moves, the telescopic rod 601 will enter the interior of the water collecting block 501, causing the accumulated water in the water collecting block 501 to flow out, until the magnetic suction block 605 is powered off at an interval under the action of the PLC controller, then the telescopic rod 504 and the floating ball 503 will return to their original positions under the action of the gravity of the telescopic rod 601, the first movable rod 602, and the second movable rod 603, thereby achieving the purpose of draining the accumulated water in the water collecting block 501. When it rains, a large amount of accumulated water will accumulate in the water storage basin 402, and the water in the water storage basin 402 will gradually flow out through the tiny holes therein. When the outflow speed is less than the accumulation speed, the water storage basin 402 The pressing rod 401 and the fixing ring 403 will be driven downward by gravity, the water storage basin 402 will give pressure to the spring 409, and the fixing ring 403 will drive the first gear 404 and the second gear 405 to rotate. The rotation of the second gear 405 will give thrust to the rack 406, and the rack 406 will drive the connecting rod 407 and the protective cover 410 to move, so that the protective cover 410 covers the outside of the water collecting block 501 to prevent rainwater from entering. When the rain stops, the water inside the water storage basin 402 will gradually flow out through the pores, and under the action of the spring 409, the protective cover 410 will be driven back to its original position, thereby achieving the purpose of protecting the water collecting block 501.

A method for detecting regional waterlogging on a highway, characterized in that: The detection is performed using the device according to any one of claims 1 to 6, comprising the following steps: Step S1, first installing the device on the outer wall of the railing (1); Step S2, when a vehicle passes by, the accumulated water will splash into the water collecting block (501), the floating ball (503) will float up and drive the telescopic rod (504) to move, and the movement of the telescopic rod (504) will block the infrared signal of the infrared sensor (604), so that the magnetic attraction block (605) will magnetically attract the telescopic rod (504), so that the top rod (505), the first conductive block (506), and the second conductive block (507) will contact each other, and the electrical signal will be transmitted to the detection terminal to remind the staff that there is water accumulation on this section of the road; Step S3, the telescopic rod (601), the first movable rod (602), and the second movable rod (603) will move simultaneously under the action of the telescopic rod (504), and the movement of the telescopic rod (601) will drain the accumulated water inside the water collecting block (501), thereby reducing the manual drainage process of the staff; Step S4, when encountering heavy rain weather conditions, a large amount of water will accumulate inside the water storage basin (402), and the increased deadweight of the water storage basin (402) will drive the pressing rod (401) and the fixing ring (403) to move downward, and apply pressure to the spring (409), and the first gear (404) and the second gear (405) will rotate under the action of the fixing ring (403), so that the rack (406), the connecting rod (407), and the protective cover (410) will move downward, and the protective cover (410) will cover the outside of the water collecting block (501) to protect the outer wall of the water collecting block (501) to prevent a large number of false alarms in heavy rain weather.
