[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] Example 1
[0026] like Figures 1 to 6As shown in the figure, a highway rainfall monitoring and early warning device according to an embodiment of the present invention includes a housing 1; the housing 1 has a sedimentation chamber 11 and a monitoring chamber 12 inside, the side wall of the sedimentation chamber 11 is connected to the monitoring chamber 12 through a set of water channels 13, and the monitoring chamber 12 is equipped with a position sensor 14; a fixing hoop 15 is fixedly connected to the side wall of the housing 1; a controller 16 is provided on the side wall of the housing 1; a grid plate 17 is hinged to the top of the housing 1, and a first square groove 18 is opened in both side walls of the sedimentation chamber 11 of the housing 1. A pair of second square grooves 19 are formed inside the first square groove 18. Circulation grooves 2 are formed on both side walls of the first square groove 18, and the first square groove 18 and the second square groove 19 are connected. A sliding column 21 is slidably connected inside the circulation groove 2. A working block 22 is slidably connected between the two side walls of the second square groove 19, and the working block 22 passes through the sliding column 21 and through the first square groove 18. The bottom of the second square groove 19 is fixedly connected to the bottom of the working block 22 by a set of springs. A check valve is provided inside the circulation groove 2, and the direction of the grid plate 17 is controlled by the check valve.
[0027] During operation, when it rains, rainwater first passes through the grating plate 17 at the top of the housing 1 to initially filter large particles of debris, and then enters the sedimentation chamber 11 for secondary sedimentation to prevent impurities from interfering with subsequent monitoring. After sedimentation, the rainwater flows into the monitoring chamber 12 through the side wall water channel 13. As the rainfall increases, the water level in the monitoring chamber 12 rises. The position sensor 14 captures the water level changes in real time and transmits the data to the controller 16. The controller 16 compares the data with the preset rainfall threshold and triggers the warning mechanism when the warning standard is reached. The fixing hoop 15 on the side wall of the housing 1 can securely install the device on the pillars along the highway to ensure stable monitoring position. The sedimentation chamber 11 is designed to avoid the problem of fluctuation in water level monitoring directly through the position sensor 14, and to prevent large particles of impurities from entering the monitoring chamber 12 to disrupt monitoring and cause subsequent blockage of the chamber. In addition, the design of the bottom spring of the working block 22 and the circulation channel 2 ensures that when the top of the grating plate 17 is pressed down due to the accumulation of impurities, the top of the grating plate 17 will bounce back after touching the bottom, ejecting the accumulated debris and achieving a cleaning effect.
[0028] The check valve includes a ring 23, which is rotatably connected to the sliding column 21. A connecting rod 24 is fixedly connected to the ring 23, and both connecting rods 24 are hinged to the bottom of the grid plate 17. The circulation groove 2 is formed by connecting the first groove 25, the first inclined groove 26, the straight groove 27, and the second inclined groove 28 end to end. A barbed spring plate 29 is fixedly connected to the sliding column 21. The side walls of the straight groove 27 and the first inclined groove 26 are provided with locking grooves 3, and the locking grooves 3 and the barbed spring plates 29 are compatible.
[0029] During operation, when rainwater impacts the grating plate 17, the grating plate 17 rotates downwards under force. The connecting rod 24 at the bottom drives the ring 23 to rotate on the sliding column 21, which in turn pushes the sliding column 21 to move gradually along the first section 25 and the oblique section 26 of the circulation groove 2. When the sliding column 21 reaches the straight section 27, the barbed spring plate 29 on it will automatically engage with the locking groove 3 on the groove wall to fix the sliding column 21. When impurities accumulate on the top of the grating plate 17 and are impacted by rainwater, one end of the grating plate 17 can only move downwards. The barbed spring plate 29 moves downwards and hooks the locking groove 3. When the sliding column 21 passes through the oblique section 26 and reaches the first section 25, the barbed spring plate 29 loses the position restriction of the limiting groove. In addition, the supporting force of the spring at the bottom of the working block 22 causes the sliding column 21 to drive the grating plate 17 to rebound quickly after touching the bottom through the connecting rod 24, throwing out the impurities accumulated on the top of the grating plate 17 and preventing them from blocking the water inlet channel on the grating plate 17.
[0030] Both the first inclined groove 26 and the second inclined groove 28 are inclined downwards towards the box 1 at the far end of the monitoring cavity 12; both sides of the bottom of the grid plate 17 are fixed with sealing plates 31, the top of the box 1 is provided with a placement groove, and an elastic membrane 32 is fixed between the top of the placement groove and the bottom of the grid plate 17.
[0031] During operation, the inclined groove 26 and inclined groove 28 in the circulation groove 2 are both inclined downwards towards the box 1 at the far end of the monitoring cavity 12. This design allows the sliding column 21 to move smoothly during opening and closing with the help of gravity, reducing jamming. When the grid plate 17 is closed, the sealing plates 31 on both sides of the bottom can fit tightly against the top edge of the box 1, enhancing the sealing effect and preventing rainwater from seeping in from the gaps. At the same time, the elastic membrane 32 between the top placement groove of the box 1 and the bottom of the grid plate 17 can act as a buffer when the grid plate 17 rotates, reducing the collision damage of the parts and preventing fallen leaves, dust and other debris from entering the placement groove.
[0032] Example 2
[0033] like Figures 1 to 6 As shown, the cross-section of the first section 25 is wavy; the cross-section of the water passage 13 is conical, and the tip of the cone is oriented towards the sedimentation chamber 11.
[0034] During operation, the cross-section of a section 25 in the circulation tank 2 is designed to be wavy. When the sliding column 21 moves in this section of the tank, the grid plate 17 is supported by the spring at the bottom of the working block 22 and rebounds quickly upward. When passing through the wavy section of the tank 25, it is subjected to bumps and vibrations, resulting in more thorough cleaning of impurities on the top of the grid plate 17. The cross-section of the water passage 13 between the sedimentation chamber 11 and the monitoring chamber 12 is set to be conical, with the tip of the cone facing the sedimentation chamber 11. This structure allows rainwater to enter the monitoring chamber 12 more slowly, avoiding large fluctuations in the water depth in the monitoring chamber 12. At the same time, the conical inner wall prevents the impurities deposited in the sedimentation chamber 11 from flowing back to the monitoring chamber 12, ensuring monitoring accuracy.
[0035] The bottom of both the sedimentation chamber 11 and the monitoring chamber 12 is a square pyramid shape, and the bottom of both the sedimentation chamber 11 and the monitoring chamber 12 is provided with a discharge pipe 4, and an electric valve 41 is provided on the discharge pipe 4.
[0036] During operation, the bottoms of both the sedimentation chamber 11 and the monitoring chamber 12 are designed as quadrangular pyramids. This shape allows the accumulated water and sedimented impurities in the chambers to gather towards the center of the bottom under gravity, facilitating centralized cleaning. Both chambers are connected to a drain pipe 4 at the bottom. Operators can periodically open the electric valve 41 on the drain pipe 4 to quickly discharge the accumulated water and impurities in the chambers. Maintenance can be completed without disassembling the device, reducing maintenance costs and operational difficulty. Since the equipment is fixed on a column, which is generally equipped with electrical equipment such as a display screen, it also provides a power source for the control module or electric valve 41 of the equipment.
[0037] The top of the monitoring chamber 12 is inclined towards the side of the chamber 1 at the far end of the sedimentation chamber 11; both sides of the working block 22 are provided with pulleys, and the pulleys are in contact with the second square groove 19.
[0038] During operation, the top of the monitoring chamber 12 is tilted towards the side of the chamber 1 at the far end of the sedimentation chamber 11, and the tilted surface can also reduce the accumulation of dust, fallen leaves and other debris.
[0039] Working principle: During daily use, due to weather conditions, debris floats and accumulates on the grid plate 17. When it rains, rainwater and the large particles it carries are initially filtered by the grid plate 17 on the top of the box 1 before entering the sedimentation chamber 11. The impurities settle in the chamber, avoiding interference with subsequent monitoring. The settled rainwater slowly flows into the monitoring chamber 12 through the conical water channel 13, reducing water level fluctuations.
[0040] The position sensor 14 inside the monitoring chamber 12 captures water level changes in real time and transmits the data to the controller 16. The controller 16 compares the data with a preset rainfall threshold and triggers an early warning when the threshold is reached.
[0041] Meanwhile, when the accumulated impurities on the grating plate 17 move downwards, the sliding column 21 moves along the circulation groove 2 through the check valve, and the spring causes the grating plate 17 to bounce back when it touches the bottom, automatically ejecting the accumulated material; the accumulated water and impurities can be discharged periodically through the electric valve 41 at the bottom of the cavity to complete the maintenance.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
