A smart manhole cover system

Abstract

This invention discloses an intelligent manhole cover system, belonging to the field of manhole cover technology. It includes a mounting base, within which a square ring is fixedly connected. A manhole seat is fixedly connected to the square ring, and a frame is fixedly connected to the top of the manhole seat. A manhole cover body is disposed within the frame, and a guide plate is fixedly connected to the mounting base, with a guide opening on the guide plate. This invention comprises a manhole cover body, a lifting assembly, and a water trough. During rainfall, rainwater continuously flows into the water trough, with only a portion draining through the drainage holes at the bottom of the trough, causing the water level to rise continuously and the overall mass of the trough to increase. When the overall mass of the trough exceeds a critical point, the trough acts on the lifting assembly, causing the lifting assembly to overcome the weight of the manhole cover body, and the trough begins to descend until it reaches its lowest position. The lifting assembly then rotates the manhole cover body by a certain angle, allowing rainwater to drain into the sewer through the opening between the manhole cover body and the manhole seat.

Description

Technical Field

[0001] This invention belongs to the field of manhole cover technology, specifically an intelligent manhole cover system. Background Technology

[0002] Manhole covers are key municipal facilities used to cover the openings of underground pipelines. They are mainly used to protect underground water supply, drainage, power, communication, and gas pipelines, ensuring road traffic safety and the safety of personnel and equipment. Currently, the mainstream manhole covers are made of ductile iron, which is suitable for the complex load conditions of municipal roads due to its high strength, high load-bearing capacity, excellent impact resistance and corrosion resistance. Among them, square manhole covers with a completely closed panel and no perforated grid have strong structural integrity and uniform stress, and can effectively withstand repeated crushing by heavy vehicles. They are widely used in heavy-load scenarios such as municipal main roads and motor vehicle lanes. This type of manhole cover relies on the drainage holes and grooves reserved on the side of the manhole seat to achieve rainwater drainage.

[0003] The existing manhole covers also have the following shortcomings: Since the manhole cover panel of the square manhole cover is completely closed, it relies on the drainage hole groove on the side of the manhole seat to achieve drainage. The drainage capacity is relatively weak. When the rainfall is heavy, water accumulation areas are easily formed on the road surface, affecting the passage of pedestrians and vehicles. It is necessary to manually open the manhole cover to drain the water. The manual response is relatively slow and it is difficult to quickly solve the water accumulation problem. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention comprises a manhole cover body, a lifting component, and a water trough. Initially, the water trough is empty of rainwater, the manhole cover body is placed horizontally, and the bottom of the manhole cover body abuts against the lifting component. The lifting component reacts to the water trough, causing it to be at its highest position. During rainfall, rainwater continuously flows into the water trough, with only a portion of the rainwater draining out through the drainage holes at the bottom of the trough, causing the water level in the trough to rise continuously and the overall mass of the trough to increase. When the overall mass of the trough exceeds a critical point, the trough acts on the lifting component, causing the lifting component to overcome the weight of the manhole cover body, and the trough begins to descend until it reaches its lowest position. The lifting component then rotates the manhole cover body at a certain angle, allowing rainwater to drain into the sewer through the opening between the manhole cover body and the manhole seat, significantly improving drainage efficiency without manual intervention and preventing rainwater from affecting traffic. After the rainfall stops, the rainwater in the trough gradually drains, reducing the weight of the trough. The manhole cover body then presses down on the lifting component, which reacts to the water trough, causing the water trough and the manhole cover body to return to their original positions.

[0016] 2. This invention is equipped with an interception plate, a cleaning component, and a waste collection bin. During rainfall, especially when the manhole cover is opened, rainwater enters the mounting base through the opening between the manhole cover and the manhole seat. The rainwater flows onto the interception plate, effectively intercepting larger debris in the rainwater to prevent it from entering the sewer and causing pipe blockage, thus ensuring smooth drainage. After the rainfall ends, the cleaning component can clean the interception plate and send the debris into the waste collection bin on one side of the interception plate for temporary storage. Workers regularly clean the debris accumulated in the waste collection bin.

[0017] 3. This invention includes a conductivity sensor, a water level sensor, a water collection funnel, a storage battery, a control box, a generator, and an impeller. Rainwater is collected in the water collection funnel and falls into the sewer. The falling rainwater impacts the blades on one side of the impeller, which drives the generator to generate electricity and charge the storage battery. The storage battery provides power to the modules, conductivity sensor, water level sensor, and cleaning components in the control box. The conductivity sensor and water level sensor monitor water quality and water level data in real time, providing data support for urban flooding early warning and sewage monitoring. When the water level sensor detects that the rainwater in the tank has been drained, the control box automatically starts the cleaning components to automatically clean the interception plate.

[0020] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0021] Example 1, referring to Figure 1 - Figure 10 This is the first embodiment of the present invention. This embodiment provides an intelligent manhole cover system that can automatically lift the manhole cover body 5 during heavy rainfall. It also provides an interception structure for rainwater debris and a related cleaning structure, including a mounting base 1, a square ring 2 fixedly connected inside the mounting base 1, a manhole seat 3 fixedly connected to the square ring 2, a frame 4 fixedly connected to the top of the manhole seat 3, a manhole cover body 5 disposed within the frame 4, a guide plate 6 fixedly connected inside the mounting base 1, a guide port on the guide plate 6, a lifting component 7 disposed on the guide plate 6, two pairs of mounting brackets 8 fixedly connected inside the mounting base 1, interception plates 9 fixedly connected to the two pairs of mounting brackets 8, interception nets disposed on the interception plates 9, a cleaning component 10 disposed at the bottom of the guide plate 6, and a water trough 11 disposed at the bottom of the interception plate 9, with fixed sides of the water trough 11. A pair of connecting blocks 12 are connected, and guide rods 13 are slidably connected to each of the connecting blocks 12. Fixing blocks 14 are fixedly connected to the top and bottom of the guide rods 13. One side of the fixing block 14 is fixedly connected to the inner wall of the mounting base 1. A conductivity sensor 15 and a water level sensor 16 are fixedly connected to the inner wall of the water tank 11. A drain hole is opened at the bottom of the water tank 11. A protective cover 17 and a water collection funnel 18 are fixedly connected to the mounting base 1. An energy storage battery 19 is fixedly connected to the bottom of the protective cover 17. A control box 20 and a generator 21 are fixedly connected to the inner wall of the protective cover 17. The input end of the generator 21 passes through the protective cover 17 and is rotatably connected to it. An impeller 22 is fixedly connected to the input end of the generator 21 on the same axis. A garbage collection box 23 is fixedly connected to the mounting base 1. An opening is opened on one side of the garbage collection box 23. It should be noted that the manhole cover body 5 is rotatably connected to the frame 4. Initially, there is no rainwater in the water trough 11, the manhole cover body 5 is placed horizontally, and the bottom of the manhole cover body 5 abuts against the lifting component 7. The lifting component 7 reacts to the water trough 11, making the water trough 11 the highest position. When it rains, rainwater falls through the manhole seat 3 onto the guide plate 6, and then through the guide port on the guide plate 6 onto the intercepting plate 9. The intercepting net on the intercepting plate 9 can intercept larger debris. Rainwater continuously flows into the water trough 11, and only a portion of the rainwater is discharged through the drainage hole at the bottom of the water trough 11, causing the water level in the water trough 11 to rise continuously. The overall mass of the water trough 11 increases. When the overall mass of the water trough 11 exceeds the critical point, the water trough 11 acts on the lifting component 7, causing the lifting component 7 to overcome the weight of the manhole cover body 5, and the water trough 11 begins to descend. The connecting block 12 slides down along the guide rod 13 until the water tank 11 reaches its lowest position. The lifting component 7 drives the manhole cover body 5 to rotate at a certain angle, so that rainwater can be discharged into the sewer through the opening between the manhole cover body 5 and the manhole seat 3, which greatly improves the drainage efficiency. No manual intervention is required, and rainwater is avoided from affecting traffic. The rainwater finally collects in the water collection funnel 18 and falls into the sewer through the water collection funnel 18. The falling rainwater can impact the blades on one side of the impeller 22. The impeller 22 drives the generator 21 to generate electricity and charge the energy storage battery 19. The energy storage battery 19 provides power to the control box 20, conductivity sensor 15, water level sensor 16 and cleaning component 10. The conductivity sensor 15 and water level sensor 16 monitor water quality and water level data in real time, providing data support for urban flooding early warning and sewage monitoring. After the rainfall stops, the rainwater in the water tank 11 will gradually drain out, reducing the weight of the water tank 11. The manhole cover body 5 will press down on the lifting component 7, and the lifting component 7 will react with the water tank 11, causing the water tank 11 and the manhole cover body 5 to reset respectively. When the water level sensor 16 detects that the rainwater in the water tank 11 has been drained out, the control box 20 will automatically start the cleaning component 10. The cleaning component 10 can clean the intercepting plate 9 and send the debris into the garbage collection bin 23 on one side of the intercepting plate 9 for temporary storage. Workers will regularly clean the debris accumulated in the garbage collection bin 23.

[0022] The lifting assembly 7 includes a pair of columnar racks 7a, both of which are slidably connected to the guide plate 6. A lifting rod 7b is fixedly connected to the top of the pair of columnar racks 7a. Two pairs of support blocks 7c are fixedly connected to the inner wall of one side of the mounting base 1. A gear 7d is rotatably connected between each pair of support blocks 7c. The gear 7d meshes with the corresponding columnar rack 7a. Two pairs of racks 7e are fixedly connected to one side of the water tank 11. Each rack 7e meshes with the corresponding gear 7d. A reinforcing rod is fixedly connected to the bottom of the pair of columnar racks 7a. It should be noted that when the water tank 11 drives the connecting block 12 to slide down along the guide rod 13, the rack 7e descends together with the water tank 11. The rack 7e drives the corresponding gear 7d to rotate. The gear 7d drives the corresponding columnar rack 7a to slide up along the guide plate 6. The columnar rack 7a drives the lifting rod 7b to lift the well cover body 5.

[0023] The cleaning component 10 includes a mounting cover 10a, which is fixedly connected to the bottom of the guide plate 6. A servo motor 10b is fixedly connected to one side of the mounting cover 10a. The output end of the servo motor 10b passes through the mounting cover 10a and is rotatably connected to it. A threaded rod 10c is coaxially fixedly connected to the output end of the servo motor 10b. The other end of the threaded rod 10c is rotatably connected to the inner wall of the mounting cover 10a. A nut 10d is threadedly connected to the threaded rod 10c. A connecting rod 10e is fixedly connected to the outer periphery of the nut 10d. A scraper 10f is fixedly connected to the bottom of the connecting rod 10e. A limiting groove is opened at the bottom of the mounting cover 10a, and the limiting groove is adapted to the connecting rod 10e. It should be noted that the protection level of the servo motor 10b is IP65 or higher, which is suitable for humid underground environments. When the control box 20 automatically starts the cleaning component 10, the output end of the servo motor 10b drives the threaded rod 10c to rotate. The threaded rod 10c drives the nut 10d to move. The nut 10d drives the scraper 10f to move through the connecting rod 10e. The connecting rod 10e slides along the limiting groove at the bottom of the mounting cover 10a. The scraper 10f can scrape off the debris on the interceptor plate 9.

[0024] The garbage collection bin 23 is equipped with a lid 31, and several water-permeable holes are opened at the bottom of the garbage collection bin 23. One side of the garbage collection bin 23 is fixedly connected to the well base 3, the square ring 2, the guide plate 6, the mounting cover 10a, and the interception plate 9 respectively. It should be noted that a groove is provided on the top of the lid 31 for placing the lid 31, and the drainage holes at the bottom of the garbage collection bin 23 can prevent water from accumulating in the garbage collection bin 23.

[0025] The control box 20 is equipped with a control management module and a monitoring module. The generator 21 is electrically connected to the energy storage battery 19 to generate and store energy. The energy storage battery 19 is electrically connected to the control management module, the monitoring module, the conductivity sensor 15, the water level sensor 16, and the servo motor 10b to provide power. The monitoring module is connected to the conductivity sensor 15 and the water level sensor 16 to collect monitoring data. The control management module is connected to the monitoring module and the servo motor 10b to receive monitoring data and control the operation of the servo motor 10b. It should be noted that the energy storage battery 19 has a built-in power regulation function, which can stabilize and store the power generated by the generator 21. The control and management module can control the working status of each power component. At the same time, the control and management module integrates a wireless transmission function, which can remotely transmit monitoring data.

[0026] Example 2, refer to Figure 11 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a protective structure for the sliding connection between the columnar rack 7a and the guide plate 6. A first mounting ring 24 is fixedly connected to the columnar rack 7a. A bellows telescopic tube 25 is fixedly connected to the bottom of the first mounting ring 24. A second mounting ring 26 is fixedly connected to the bottom of the bellows telescopic tube 25. The bottom of the second mounting ring 26 is fixedly connected to the guide plate 6. A pair of vent holes are provided on the guide plate 6. It should be noted that the first mounting ring 24 can rise and fall together with the columnar rack 7a, and the bellows telescopic tube 25 extends and retracts accordingly. The bellows telescopic tube 25, together with the first mounting ring 24 and the second mounting ring 26, can cover the sliding connection between the columnar rack 7a and the guide plate 6 to prevent mud and sand in the rainwater from entering. When the bellows telescopic tube 25 extends and retracts, the air inside and outside the bellows telescopic tube 25 can circulate through the vent holes on the guide plate 6. The vent holes are vertical.

[0027] The rest of the structure is the same as in Example 1.

[0028] Example 3, referring to Figure 7 , Figure 9 and Figure 10 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a rainwater guiding structure. A guide strip 27 is fixedly connected to the top of the mounting cover 10a. Both ends of the guide strip 27 are fixedly connected to the guide port. A pair of first guide baffles 28 are fixedly connected to both sides of the mounting cover 10a. A pair of second guide baffles 29 are fixedly connected to both sides of the water tank 11. A guide frame 30 is fixedly connected to the bottom of the interception plate 9. An overflow port is opened on both sides of the water tank 11. It should be noted that the cross-section of the guide strip 27 is an isosceles triangle, allowing rainwater to fall along the side of the guide strip 27. The first guide baffle 28 is tilted, allowing rainwater to fall along the water-facing surface of the first guide baffle 28, preventing rainwater from flowing freely along both sides of the mounting cover 10a when falling. When the water level in the water tank 11 is equal to the overflow outlets on both sides of the water tank 11, rainwater flows out through the overflow outlets. The second guide baffle 29 is vertical, allowing rainwater to fall between the pair of second guide baffles 29 into the water collection funnel 18, preventing rainwater from flowing freely along both sides of the water tank 11 when falling.

[0029] The rest of the structure is the same as in Example 2.
