[0002] In the current market, water well covers can be divided into four categories according to material, namely metal well covers, high-strength steel fiber cement concrete well covers (cement-based composite materials), recycled resin well covers (recycled resin-based composite materials), and polymer-based composite material inspection well covers. In the current market, water well covers can be divided into circular and square shapes according to shape.

[0043] II. Equipment Assembly Process First, complete the pouring construction of drainage well 1, and reserve cavity B, installation groove and filter screen plate 5 fixing steps. After the concrete strength reaches the standard, fix filter screen plate 5 to the steps with bolts.

[0044] Install the lifting assembly 8 in the cavity B on the right side: fix the screw 81 through the bearing seat, install the synchronous pulley at the lower end and sleeve the synchronous belt 811, fix the servo motor B82 at the bottom and connect it to the rear screw 81; insert the threaded sleeve B83 into the screw 81, insert the sliding plate 831 into the sliding rod 832, and the upper end of the L-shaped lifting rod 84 passes through the reserved hole at the top of the drainage well 1.

[0047] Install sensing and control components: fix hydraulic sensor 9 to the inner wall of drainage well 1, fix alarm 4 to the bottom of cavity A, fix control panel 7 to the left cavity B, complete the cable connection of each component and waterproof it.

[0048] Finally, the manhole cover frame 2 is fitted and installed on the top of the drainage well 1, ensuring that the upper ends of the L-shaped lifting rod 84 and the upright rod 61 are fixedly connected to the bottom of the manhole cover frame 2, thus completing the overall assembly.

[0049] III. Drainage Methods and Work Process (a) Scenario of light rain in daily life (water level not reaching hydraulic sensor 9) Rainwater flows into the drainage well 1 through the gap between the movable drainage plate 37 and the fixed drainage plate 38 inside the manhole cover frame 2, and is discharged after being filtered by the filter screen plate 5. Impurities are trapped on the filter screen plate 5.

[0050] Adjustment component 3 and lifting component 8 are in their initial state, the distance between the movable drainage plate 37 and the fixed drainage plate 38 remains at the initial value (50mm), and the alarm 4 is not working.

[0051] (ii) Moderate to heavy rain scenario (water level close to hydraulic sensor 9) When the water level on the road increases and the drainage pressure of the manhole cover frame 2 increases, the hydraulic sensor 9 detects the rise in water level (but does not reach the trigger threshold). The control panel 7 can control the servo motor A31 to start according to the preset program (before the lifting component 8).

[0052] Servo motor A31 drives turntable 32 to rotate, fixed shaft 33 slides in sliding frame 34 and pushes sliding frame 34 to move backward (limit telescopic rod 341 extends to guide), L-shaped connecting rod 35 drives moving plate 36 to move backward, fixed rod 371 pulls moving drainage plate 37 closer to fixed drainage plate 38, the distance between the two increases to 100mm, the drainage outlet expands, and the drainage rate is accelerated.

[0053] (III) Heavy rain scenario (water level reaches the trigger threshold of hydraulic sensor 9) Signal Triggering and Warning: The hydraulic sensor 9 transmits the water level signal to the control panel 7, which immediately activates the alarm 4, emitting an audible and visual alarm to remind passersby to pay attention to the water accumulation area and the status of the manhole cover.

[0054] Manhole cover lifting: Control panel 7 starts servo motor B82, which drives the rear screw 81 to rotate. The front screw 81 rotates synchronously through synchronous belt 811. The threaded sleeve B83 moves upward under the action of screw 81 (sliding plate 831 is guided along sliding rod 832). L-shaped lifting rod 84 pushes manhole cover frame 2 upward to a height of 100-150mm from the top of drainage well 1, realizing the large opening and closing of drainage well 1, greatly improving drainage efficiency.

[0055] Impurity removal: During the rising of the manhole cover frame 2, the upright 61 drives the moving rack plate 62 to move upward, meshing with the driving gear 63 to rotate, and the threaded rod 64 rotates accordingly. The threaded sleeve A65 moves to the right under the guidance of the U-shaped guide rod 652, and drives the scraper 67 to slide to the right along the top of the filter screen plate 5 through the L-shaped rod 671, scraping the trapped impurities to the right edge of the filter screen plate 5 (for easy subsequent manual cleaning), avoiding impurities clogging and affecting drainage.

[0056] (iv) Reset scene after rain As rainwater drains and the water level on the road decreases, hydraulic sensor 9 detects that the water level has dropped to a safe value and sends feedback to control panel 7.

[0057] Control panel 7 controls servo motor B82 to reverse, driving manhole cover frame 2 to move downwards and reset, fitting the top of drainage well 1; synchronously driving moving rack plate 62 downwards, and through gear transmission, scraper 67 moves to the left and resets.

[0058] Servo motor A31 reverses, causing the movable drainage plate 37 to reset, restoring the initial distance between it and the fixed drainage plate 38; alarm 4 stops working, and the device returns to its normal standby state.

[0059] IV. Precautions and Maintenance Requirements After installation, the device needs to be debugged to ensure that the movements of each component (adjustment component 3, lifting component 8, wall scraping component 6, etc.) are coordinated, and that the sensitivity of the sensor (hydraulic sensor 9), the stroke of the motor (servo motor A31, servo motor B82), and the volume of the alarm 4 meet the requirements of the actual scenario.

[0060] Regularly (once a month) check the filter screen 5 for impurity buildup and promptly clean the impurities scraped to the edge by the scraper 67; check the lubrication and wear of each transmission component (synchronous belt 811, movable gear 63, screw 81, threaded rod 64), and replenish grease or replace parts if necessary.

[0061] Every quarter, waterproof and functional tests are conducted on servo motor A31, servo motor B82, hydraulic sensor 9, and control panel 7 to ensure stable operation in humid environments; enhanced inspections are required before the rainy season to prevent circuit failures.

[0062] When the device malfunctions (such as false alarm of alarm 4 or component jamming), the control panel 7 can record the fault information to facilitate troubleshooting by maintenance personnel. During maintenance, the power supply to the device must be disconnected first to ensure operational safety.

[0063] This implementation method achieves automatic adjustment of drainage, anti-clogging, safety warning and intelligent reset functions of the well cover through the collaborative work of multiple components. It can effectively cope with different rainfall scenarios, improve urban drainage efficiency, reduce the risk of waterlogging and meet actual use needs.

[0064] Working Principle: During use, the drainage well 1 and the well cover frame 2 work together to facilitate rainwater drainage, effectively clearing accumulated water from the road during rainy days. Furthermore, the filter screen 5 filters impurities from the rainwater, preventing blockages in the drainage pipes. When the water level reaches the hydraulic sensor 9, it sends a signal to the control panel 7. The control panel 7 then controls the servo motor B82, which in turn drives the rear screw 81 to rotate. Under the transmission of the synchronous belt 811, this drives the front and rear screws 81 to rotate synchronously. The rotation of the screw 81 drives the adjacent threaded sections... When the threaded sleeve B83 moves upward, it drives the adjacent L-shaped lifting rod 84 to move upward. This, in turn, moves the manhole cover frame 2 upward, thus opening and closing the drainage well 1 and accelerating rainwater drainage. As the manhole cover frame 2 moves upward, it also drives the moving rack plate 62 upward via the upright rod 61. The upward movement of the moving rack plate 62 drives the movable gear 63 to rotate, which in turn drives the threaded rod 64 to rotate. The rotation of the threaded rod 64 then drives the threaded sleeve A65 to move to the right. The rightward movement of the threaded sleeve A65, in turn, drives the L-shaped rod 671 to... The scraper 67 moves to the right on the filter screen 5, scraping impurities from the filter screen 5 to the top right side of the filter screen 5, further improving the rainwater drainage rate. Furthermore, before moving the manhole cover frame 2 upwards, the servo motor A31 can be activated. When the servo motor A31 operates, it drives the turntable 32 to rotate. The rotation of the turntable 32, in turn, drives the sliding frame 34 to move backwards via the fixed shaft 33. The backward movement of the sliding frame 34 also drives the L-shaped connecting rods 35 on both sides to move backwards. The backward movement of the L-shaped connecting rods 35 drives the adjacent moving plate 36 to move backwards. When in motion, the adjacent fixed rod 371 will drive the adjacent movable drainage plate 37 to move backward, which will move the movable drainage plate 37 to the side closer to the fixed drainage plate 38, thus opening the drain outlet and allowing rainwater to drain. In addition, when the water level reaches the hydraulic sensor 9, it will transmit a signal to the control panel 7, and at this time the control panel 7 will also control the alarm 4 to run. When the alarm 4 is running, it will sound an alarm to alert passers-by. After the rainwater drains, the hydraulic sensor 9 will also transmit a signal to the control panel 7, which will then drive the manhole cover frame 2 to move downward and return to its original position, resulting in excellent drainage.

A drainage method for a well cover with automatic opening and closing and warning functions, characterized in that, A water well cover with automatic opening and closing and warning functions as described in any one of claims 1-9, wherein the drainage method includes the following steps: S1: When in use, the cooperation between the drainage well (1) and the well cover frame (2) facilitates the drainage of rainwater and plays a role in clearing water accumulation on the road surface during rainy days; S2: In addition, the filter screen (5) is set to filter impurities in the rainwater to avoid blockage of the drainage pipe. When the water level reaches the hydraulic sensor (9), it will transmit the signal to the control panel (7). The control panel (7) will control the servo motor B (82) to run. When the servo motor B (82) runs, it will drive the screw (81) on the rear side to rotate. Under the transmission of the synchronous belt (811), it will drive the screws (81) on the front and rear sides to rotate synchronously. When the screw (81) rotates, it will drive the adjacent threaded sleeve B (83) to move upward. When the threaded sleeve B (83) moves upward, it will drive the adjacent L-shaped lifting rod (84) to move upward. At this time, it can drive the manhole cover frame (2) to move upward together, so as to realize the opening and closing of the drainage well (1) and speed up the drainage of rainwater. S3: When the manhole cover frame (2) moves upward, it will also drive the moving rack plate (62) to move upward through the upright (61). When the moving rack plate (62) moves upward, it will drive the movable gear (63) to rotate. When the movable gear (63) rotates, it will drive the threaded rod (64) to rotate. When the threaded rod (64) rotates, it will drive the threaded sleeve A (65) to move to the right. When the threaded sleeve A (65) moves to the right, it will drive the scraper (67) to move to the right on the filter screen plate (5) through the L-shaped rod (671). This will scrape the impurities on the filter screen plate (5) to the right side of the top of the filter screen plate (5), further improving the rate of rainwater drainage. S4: In addition, before the manhole cover frame (2) is moved upward, the servo motor A (31) can be run. When the servo motor A (31) is running, it will drive the turntable (32) to rotate. When the turntable (32) rotates, it will drive the sliding frame (34) to move backward through the fixed shaft (33). When the sliding frame (34) moves backward, it will also drive the L-shaped connecting rods (35) on both sides to move backward. When the L-shaped connecting rods (35) move backward, they will drive the adjacent moving plate (36) to move backward. When the moving plate (36) moves backward, it will drive the adjacent moving drainage plate (37) to move backward through the adjacent fixed rod (371). This will drive the moving drainage plate (37) to move closer to the fixed drainage plate (38), thus opening the drain outlet and allowing rainwater to drain. S5: In addition, when the water level reaches the hydraulic sensor (9), it will transmit the signal to the control panel (7), and at this time the control panel (7) will also control the alarm (4) to run. When the alarm (4) runs, it will sound an alarm to alert passersby. S6: After the rainwater is drained, the hydraulic sensor (9) will also transmit the signal to the control panel (7), which will then drive the manhole cover frame (2) to move downwards to restore its original position, resulting in a good drainage effect.
