Detailed implementation mode

[0014] Now, the present invention will be further described in detail through embodiments with reference to the accompanying drawings, but the present invention is not limited to the embodiments.

[0015] As Figure 1-8 shown, the present invention is an intelligent cover for a rainwater catch well, including a manhole cover 1, and further including a lifting part, a power supply part, a control part, a sundries collection net bag 5, and a mounting plate 6 with a central opening for mounting on the well wall of the rainwater catch well.

[0016] As Figure 5 shown, a dust-proof baffle 11 is provided at the water outlet hole of the manhole cover 1. Specifically, a rotating shaft is installed on the bottom surface of the manhole cover 1 at the edge of the water outlet hole, and a torsion spring 12 is sleeved on the rotating shaft. The dust-proof baffle 11 is hinged on the rotating shaft and supported by an arm of the torsion spring 12. When there is no rain, the dust-proof baffle 11 is kept in a horizontal closed state under the support of the torsion spring arm, which can prevent dust and sundries from getting stuck or entering the water outlet hole; when the rainfall is large, the rainwater increases the overall weight of the dust-proof baffle 11. When the rainwater accumulates to a certain amount, the dust-proof baffle 11 is turned downward under the action of the water weight, and the tension of the torsion spring 12 is released, opening the water outlet hole to realize the discharge of rainwater; after the rain stops and the rainwater is drained out, the elastic force of the torsion spring 12 pushes the dust-proof baffle 11 back to the closed position to block the dust and sundries from entering.

[0017] As Figure 2 , Figure 6 , Figure 7As shown in the figure, the lifting part includes a hydraulic scissor lifting platform 21, a rectangular ring-shaped aluminum alloy tabletop 22, telescopic rods 23, and a movable filter screen 24; the hydraulic scissor lifting platform 21 has a top frame 211 and a bottom frame 212. The top of the top frame 211 is installed at the bottom of the tabletop 22, and the bottom frame 212 is installed on the mounting plate 6; the telescopic rods 23 are in two opposite rows. The upper ends of the telescopic rods 23 are installed at the bottom of the tabletop 22, and the lower ends are installed on the mounting plate 6. The hydraulic scissor lifting platform 21 is located between the two rows of telescopic rods 23; the top of the movable filter screen 24 is detachably installed at the bottom of the tabletop 22, and the bottom is detachably installed on the mounting plate 6. The movable filter screen 24 is located between the two rows of telescopic rods 23 and surrounds the hydraulic scissor lifting platform 21; the well cover plate 1 is installed on the top of the tabletop 22, and the opening on the mounting plate 6 is directly below the well cover plate 1. After the lifting part is disassembled, it can allow personnel to enter the well. Warning signs 25 are painted on the circumferential surface of the well cover plate 1, the circumferential surface of the tabletop 22, and the telescopic rods 23. The above warning signs 25 are eye-catching fluorescent signs; the top of the sundry collection net bag 5 is detachably installed on the lower surface of the mounting plate 6 for collecting sundries falling from the opening of the mounting plate 6.

[0018] The above hydraulic scissor lifting platform 21 can refer to the prior art, such as Figure 2 As shown in the figure, it includes components such as hydraulic cylinders 213, hydraulic pumps, hydraulic valves, oil pipes, scissor arms, and cylinder pins 214; the top frame 211 of the hydraulic scissor lifting platform 21 is used for placing items, and the bottom frame 212 is used to support the entire lifting platform.

[0019] Such as Figure 1 As shown in the figure, rubber buffer pads 221 are installed on the edge and four corners of the bottom surface of the tabletop 22. Such as Figure 5As shown in the figure, on both sides of the lower surface of the tabletop 22 (both long sides), a storage groove 222 recessed upward is provided. The upper ends of two rows of telescopic rods 23 are respectively installed in the two storage grooves 222. The telescopic rods 23 are made of stainless steel or aluminum alloy. Each telescopic rod 23 has a multi-section nested structure, and the diameter decreases sequentially from bottom to top, so that they can be nested step by step to achieve the telescopic function. The depth and width of the storage groove 222 can be designed according to the size of the telescopic rod 23 after contraction, but it is necessary to ensure that the well cover 1 does not protrude from the road surface after the telescopic rod 23 contracts. When the well cover 1 is raised, an operation gap (for example, with a height of more than 30 cm) is formed between the short side of the tabletop 22 and the ground. The operator can remove the movable filter screen 24 and directly pick up the sundries at the bottom of the sundry collection net bag 5 or directly remove the sundry collection net bag 5 for cleaning through this gap with a long-handled tool (such as an L-shaped clamp). Daily cleaning only needs to be operated through the gap between the short side of the tabletop 22 and the ground, avoiding the safety risks and time-consuming problems brought by frequent disassembly of the sundry collection net bag 5. The two rows of telescopic rods 23 are only arranged on the long sides of the tabletop 22 as guardrails to protect pedestrians and vehicles. The gap design between the short side of the tabletop 22 and the ground balances safety protection and maintenance convenience. The sundry collection net bag 5 is independently detachable, reducing maintenance costs and increasing the service life of the equipment.

[0020] As Figure 2 , Figure 6 , Figure 7As shown, the mounting plate 6 is formed by butt - jointing two L - shaped plates and is connected by stainless - steel bolts. The bolt head is designed with an internal hexagon, and the pre - tightening force requirement reaches 150 N·m. A positioning pin is set at the butt - joint of the two L - shaped plates to ensure the accuracy and stability during installation. The mounting plate 6 is fixed to the well wall through expansion bolts. Even if a small amount of debris enters through the gap between the movable filter screen 24 and the ground, it will deposit on the upper surface of the mounting plate 6 and will not enter the sewer to cause siltation and blockage. Four hooks are provided at both the top and bottom of the movable filter screen 24. At the bottom of the tabletop 22, there are hanging rings corresponding to the top hooks of the movable filter screen 24, and on the upper surface of the mounting plate 6, there are hanging rings corresponding to the bottom hooks of the movable filter screen 24. The movable filter screen 24 is detachably installed between the tabletop 22 and the mounting plate 6 through the hooks and hanging rings. The positions of the above - mentioned hanging rings are staggered from the telescopic rod 23 to ensure that there is no interference when the telescopic rod 23 expands and contracts. The top of the debris collection net bag 5 is provided with four hooks, and on the lower surface of the mounting plate 6, there are corresponding hanging rings. The debris collection net bag 5 is detachably installed on the mounting plate 6 through the hooks and hanging rings. The above - mentioned hooks are, for example, stainless - steel safety hooks, and the surface is treated with galvanization to enhance its corrosion resistance. The hanging rings are, for example, lifting rings 61, and the lifting rings 61 are made of high - strength alloy steel, with a single - point tensile strength ≥ 200 N. Rainwater naturally flows into the well through the mesh holes of the debris collection net bag 5. The suspended design at the bottom of the debris collection net bag 5 avoids the deposition of debris at the bottom, ensuring the smoothness of drainage. The movable filter screen 24 intercepts larger debris, reducing the burden on the debris collection net bag 5; the debris collection net bag 5 further filters fine particles, providing double protection to prevent sewer blockage. When in - depth maintenance is required, the debris collection net bag 5 can be removed from the lifting ring 61 for a comprehensive cleaning and inspection. After the maintenance is completed, the debris collection net bag 5 is reinstalled in the reverse steps. Four support rods are also provided on the upper surface of the mounting plate 6 to support the lowered tabletop 22.

[0021] As Figure 6 , Figure 7 shown, the size of the movable filter screen 24 matches the inner space between the two rows of telescopic rods 23. After the hydraulic scissor lift platform 21 rises, the movable filter screen 24 unfolds to be perpendicular to the ground, forming a physical barrier. The mesh design allows rainwater to pass through while intercepting large debris such as branches and plastic bags, avoiding the entanglement of debris with the scissor arms or the piston rods of the hydraulic cylinders and reducing the risk of jamming. After the hydraulic scissor lift platform 21 descends in place, the support column 62 cooperates with the bottom of the tabletop 22 to support the tabletop 22, dispersing the weight, preventing the deformation of the bottom of the tabletop 22, ensuring that the tabletop 22 remains horizontal, and avoiding tilting and shaking; the support column 62, together with the hydraulic cylinder 213 and the scissor arms, constitutes a force - bearing system, bearing the vertical load, enhancing the overall load - bearing capacity of the device, and ensuring the safety of the device.

[0022] As Figure 3As shown in the figure, the power supply unit includes a column 31 for installation on the side of the moving walkway, and a solar panel 32 and a power storage device 33 both installed on the column 31. The solar panel 32 and the power storage device 33 are connected by an electric wire 34. The solar panel 32 converts solar energy into electrical energy and stores it in the power storage device 33.

[0023] As Figure 1-3 , Figure 5-7 shown in the figure, the control unit includes a controller 41, a remote control terminal, a force sensor 46 installed on the hydraulic scissor lift platform 21, a rainfall meter 42 installed on the column 31, a remote control signal receiver 43 installed on the manhole cover 1, and a water level sensor for installation on the wall of the rainwater catchment well. The chip model of the controller 41 is STM32. The controller 41 is installed on the side wall of the tabletop 22. The above-mentioned power storage device 33 is electrically connected to the controller 41 and the hydraulic scissor lift platform 21. The controller 41 is connected to the hydraulic scissor lift platform 21, the force sensor 46, the rainfall meter 42, the remote control signal receiver 43, and the water level sensor. The remote control terminal receives signals from the remote control signal receiver 43 and / or sends instructions to the remote control signal receiver 43. The above-mentioned remote control signal receiver 43 can use a single-chip wireless transceiver chip nRF24L01 or a 433MHz / 315MHz wireless receiving module, and can be extended to support wide area network communication (such as a GPRS / 4G module).

[0024] The above-mentioned force sensor 46 is installed at the connection between the piston rod of the hydraulic cylinder 213 and the cylinder pin 214 to monitor the telescopic resistance in real time. When the resistance exceeds the threshold (such as jamming), the force sensor 46 sends a signal to the controller 41. After receiving the signal, the controller 41 sends a control instruction to the actuator (such as a hydraulic pump and a hydraulic valve) of the hydraulic scissor lift platform 21, thereby controlling the hydraulic scissor lift platform 21 to stop the lifting action. At the same time, the controller 41 controls the remote control signal receiver 43 to send an alarm signal to the remote control terminal. After receiving the signal, the remote control terminal notifies the maintenance personnel for maintenance; the force sensor 46 can select Zemic BHR-4 with a measuring range of 0-15kN, which is waterproof, dustproof and has strong anti-impact ability.

[0025] The above rainfall gauge 42 is installed on the sidewalk side of the road, monitors the rainfall during rain, and sends a rainfall signal to the controller 41. The above rainfall gauge 42 can use a tipping bucket rain gauge HY / SW-RG. The water level sensor includes a high water level sensor 44 and a low water level sensor 45. The high water level sensor 44 is installed at a height of 2 / 3 from the bottom of the well and is used to trigger the instruction to raise the well cover plate 1. The low water level sensor 45 is installed at a height of 1 / 3 from the bottom of the well and is used to trigger the instruction to lower the well cover plate 1. The above water level sensor can use a CHZB-S float type water level sensor. The water level sensor can monitor the water level change in the well in real time. When the water level reaches the preset high water level threshold, the water level sensor sends a signal to the controller 41. The controller 41 can use an STM32 controller or a programmable logic controller PLC, such as Siemens' S7-1200, which has a high protection level, dustproof and waterproof, and is suitable for use in harsh environments. The controller 41 makes judgments and decisions according to the received water level sensor signal and the above rainfall signal according to the preset program and logic. If it is judged that the well cover plate 1 needs to be raised, the controller 41 sends a control instruction to the actuator (such as a hydraulic pump and a hydraulic valve) of the hydraulic scissor lift platform 21 to start the raising action; similarly, when the water level drops to the low water level threshold, the controller 41 issues a lowering instruction to lower the hydraulic scissor lift platform 21 back to the initial state; at the same time, the controller 41 controls the remote control signal receiver 43 to send a signal to the remote control terminal. If there are staff near this device, the remote control can be used to send a signal to the remote control signal receiver 43. After receiving the signal, the remote control signal receiver 43 forwards it to the controller 41. After receiving the signal, the controller 41 controls the hydraulic scissor lift platform 21 to lift and lower to complete the opening and closing of the well cover plate 1; if it is remote, a signal can be sent to the remote control signal receiver 43 through a remote networked computer. After receiving the signal, the remote control signal receiver 43 forwards it to the controller 41. After receiving the signal, the controller 41 controls the hydraulic scissor lift platform 21 to lift and lower to complete the opening and closing of the well cover plate 1. The above remote networked computer can communicate with the remote control signal receiver 43 through a 4G / GPRS module + cloud platform. The above water level threshold and response time can be set as needed to adapt to different rainfall intensities and drainage requirements. At the same time, this device can also be networked with other drainage systems or urban management systems to achieve remote monitoring and collaborative work, improving the operation efficiency and management level of the entire drainage system.

[0026] The above remote control uses wireless communication technology, such as radio frequency signals or Bluetooth signals, to communicate with the remote control signal receiver 43 of the well cover plate 1. Basic control buttons such as extend, retract, and stop are provided on the remote control, for example; pairing and coding settings are required between the remote control and the remote control signal receiver 43 to prevent misoperation and signal interference.

[0027] The method of operation of the present invention is as follows.

[0028] Working condition 1: When there is no rain or the rainfall is small When the rainfall meter 42 detects no rainfall or the rainfall is small, the manhole cover 1 is flush with the road surface, and the rubber buffer pad 221 contacts the mounting plate 6 to absorb the impact of the road surface. At this time, the torsion spring maintains the tension, so that the dust baffle 11 is horizontally closed to completely cover the drainage hole.

[0029] When the rainfall is small and the water level does not reach the threshold of the low water level sensor 45, the accumulated rainwater plus the weight of the dust baffle 11 exceeds the spring tension, and the dust baffle 11 flips downward around the rotating axis to open the drainage hole. After the dust baffle 11 is opened, rainwater flows into the well, and the dust baffle 11 still intercepts larger debris. At this time, the controller 41 continues to collect data and does not trigger the action of the hydraulic scissor lift platform 21, which can achieve light rain drainage and take into account the interception function to avoid road water accumulation.

[0030] Working condition 2: When the rainfall increases When the rainfall meter 42 detects that the rainfall increases or the water level reaches the threshold of the high water level sensor 44, a signal is sent to the controller 41. After receiving the signal, the controller 41 automatically controls the hydraulic scissor lift platform 21 to rise until it reaches a preset height. Alternatively, the worker can use a remote control or a remote networked computer to issue a command to the remote control signal receiver 43. After receiving the command, the controller 41 controls the hydraulic scissor lift platform 21 to rise until it reaches a preset height. The manhole cover 1, the table 22, the telescopic rod 23, and the movable filter 24 extend out of the road surface. The movable filter 24 realizes road drainage and prevents debris on the ground from entering the hydraulic scissor lift platform 21. The warning signs 25 on the manhole cover 1, the table 22, and the telescopic rod 23 remind passers-by and vehicles that the manhole cover 1 here has been raised. At this time, rainwater flows in freely, which can cope with heavy rainfall and prevent waterlogging.

[0031] Working condition 3: When the hydraulic scissor lift platform 21 is stuck by debris during the lifting process The force sensor 46 detects that the resistance of the hydraulic cylinder 213 exceeds the threshold value, determines that it is stuck, and sends a signal to the controller 41. The controller 41 controls the hydraulic scissor lift platform 21 to cut off the oil circuit and stop lifting to prevent damage to the device due to forced lifting. The fault code is sent to the remote control terminal through the remote control signal receiver 43, and the maintenance personnel are notified to perform maintenance at the same time. The maintenance personnel remove the obstruction and restart the system after confirming that there is no abnormality.

[0032] Condition 4: After the rainfall decreases When the rainfall gauge 42 monitors a decrease in rainfall or the water level reaches the threshold of the low water level sensor 45, it sends a signal to the controller 41. After receiving the signal, the controller 41 controls the hydraulic scissor lift platform 21 to lower, and the well cover 1, the tabletop 22, the telescopic rod 23, and the movable filter screen 24 also contract accordingly. At this time, the well cover 1 is flush with the road surface.

[0033] For the technologies not specifically mentioned above, reference is made to the prior art.

[0034] Taking the ideal embodiments of the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification.
