Description

Technical Field

[0001] This utility model relates to the field of urban drainage technology, and in particular to a device for draining water from urban roads. Background Technology

[0002] The widespread hardening of surfaces has prevented rainwater from being absorbed by the soil and instead causes it to enter the sewers, overburdening urban drainage systems and leading to road flooding. Urban road flooding drainage devices primarily guide water from the surface of urban roads to underground drainage networks or water bodies through the drainage system, thereby reducing the height of water accumulation on the road surface. They are important facilities for the effective management and drainage of water accumulation on urban roads, improving the efficiency of urban drainage systems, reducing the probability of urban flooding, mitigating flood risks, and maintaining road traffic safety.

[0003] Existing urban road drainage systems are not suitable for crushing larger impurities in actual use. Larger impurities accumulate and clog drainage pipes, affecting normal drainage.

[0004] A search of existing patents reveals a device for draining urban road flooding (publication number: CN208844698U), comprising a drainage tank, a garbage bin fitted onto the inner wall of the top of the drainage tank, a cross-shaped support plate vertically connected to the bottom of the garbage bin, a support rod fixedly connected to the bottom of the cross-shaped support plate by welding, a water collection tank fixedly connected to the bottom of the support rod by welding, a drainage pipe located on the left side of the bottom of the water collection tank, a float chamber located on one side of the inner cavity of the drainage tank, and a float valve connected to the bottom of the float chamber. This type of urban road flooding drainage device is simple and low-cost, with most of the device not exposed on the ground surface. The float rod, with water level markings, allows for monitoring of the current water level as it rises. The S-shaped drainage pipe enables faster drainage, and the filter screen at the bottom of the garbage bin's inner wall intercepts most of the garbage. Therefore, this type of urban road flooding drainage device has broad application prospects.

[0005] While the aforementioned patent achieves simple equipment and low cost, with most of the device not exposed on the ground surface, and can drain water more quickly through the S-shaped drainage pipe, and can intercept most of the garbage through the filter screen at the bottom of the inner wall of the garbage can, it is not easy to reduce the silt and impurities inside the drainage pipe, which can easily lead to silt accumulation and blockage in the drainage pipe.

[0006] Therefore, it is necessary to invent a device for draining water from urban roads to solve the above problems. Utility Model Content

[0007] The technical problem solved by the utility model is to provide a drainage device for urban roads, which solves the problem mentioned in the background art that it is not easy to reduce the silt and impurities inside the drainage pipe, and that the drainage pipe is prone to silt accumulation and blockage.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: comprising an inlet tank, a sedimentation tank, and a slag discharge bin, characterized in that:

[0009] The inlet of the water inlet tank is provided with a tank cover, the tank cover is provided with a number of filter holes, and a pulverizing component is provided inside the water inlet tank;

[0010] The water inlet tank is connected to the upper part of the sedimentation tank;

[0011] The upper part of the sedimentation tank is equipped with a drainage component, and the bottom of the sedimentation tank is connected to the slag discharge bin through a conveying pipe. The conveying pipe is equipped with a conveying component.

[0012] The upper part of the slag discharge bin is provided with a discharge port, and a lifting component is provided inside the slag discharge bin corresponding to the discharge port. The lifting component lifts the slag inside to the discharge port for discharge.

[0013] The water inlet trough of this solution is set in a low-lying area. After rainwater containing leaves enters the water inlet trough, it is crushed by the crushing component to reduce the volume of the waste and facilitate transportation. Then it enters the sedimentation tank. In the sedimentation tank, solid waste will settle at the bottom, and water will be discharged to the outside through the drainage component. The solid waste at the bottom is transported to the slag discharge bin by the conveying component. The lifting component in the slag discharge bin will discharge the solid waste from the discharge port.

[0014] Preferably, the pulverizing assembly includes a rotating shaft, pulverizing blades, and a synchronizing gear. The two sets of rotating shafts are parallel to each other and rotate in cooperation with the side wall of the water inlet tank. The side wall of the rotating shaft is provided with a plurality of pulverizing blades. The rotating shaft is driven by a pulverizing motor. The ends of the two rotating shafts are respectively provided with the synchronizing gears that mesh with each other.

[0015] Two sets of crushing blades are used. Since the rotating shafts are meshed by synchronous gears, they can rotate synchronously in opposite directions, which improves the crushing effect.

[0016] Preferably, a support base is provided on the outside of the water inlet tank, and the pulverizing motor is fixed to the support base. One of the rotating shafts extends to the outside of the water inlet tank and is fixed to the rotor of the pulverizing motor. This facilitates the fixing of the pulverizing motor.

[0017] Preferably, the inlet tank and the sedimentation tank are connected by a slag discharge pipe. This allows for a more independent installation of the sedimentation tank.

[0018] Preferably, the lower part of the sedimentation tank has a conical structure, which facilitates the transport of solid waste to the slag discharge bin via a conveying pipe.

[0019] Preferably, the conveying assembly includes an auger and a conveying motor, the auger being rotatably fitted inside the conveying pipe, and the rotor of the conveying motor being connected to the auger. This allows for more sufficient conveying power.

[0020] Preferably, the lifting assembly includes pulleys, a synchronous belt, and a conveyor bucket disposed around the synchronous belt. The lower and upper parts of the slag discharge bin are each equipped with pulleys, one of which is driven by a synchronous motor. The synchronous belt is wound around both pulleys. The discharge port is located on the side of the conveyor bucket that is inverted. As the conveyor bucket moves upward, it can scoop up the waste. When the conveyor bucket turns towards the discharge port, inertia allows it to dump the waste towards the discharge port, thus achieving the effect of removing the waste from the slag discharge bin.

[0021] Preferably, the slag discharge bin includes a lower bin and an upper bin that are interconnected. Each bin is equipped with a pulley. The width of the upper bin is adapted to the width of the conveyor bucket. The discharge port is located on the side wall of the upper bin, and a chute is provided outwards along the lower edge of the discharge port. By using an upper bin adapted to the width of the conveyor bucket, waste is less likely to fall from the left or right sides of the bucket. When the bucket turns towards the discharge port, the waste is more easily discharged from the outlet.

[0022] Preferably, the drainage assembly includes a suction pipe extending from the outside of the sedimentation tank to the inside of the sedimentation tank, and the suction pipe is equipped with a high-pressure water pump. This facilitates the extraction of water from the sedimentation tank. During the extraction process, the internal air pressure decreases, which can provide negative pressure for the waste flowing from the inlet tank to the sedimentation tank.

[0023] Preferably, the upper end of the sedimentation tank is provided with a removable maintenance cover. This facilitates maintenance in case of blockages or other problems in the sedimentation tank.

[0024] The beneficial effects of this solution are:

[0025] This utility model provides a device for draining urban road floodwater, which has the following beneficial effects:

[0026] 1. This urban flood drainage device, through the arrangement of conveying and lifting components, allows urban road floodwater mixed with silt to enter the sedimentation tank through the inlet channel during use. This sedimentation causes the drive motor to rotate, pulling the silt from the bottom of the sedimentation tank through the conveying pipe into the collection tank. The output motor then starts, driving the rotating wheel. The conveyor belt on the rotating wheel moves the transport bucket to transport the silt and impurities from the bottom to the protective box. Using inertia, the silt and impurities in the transport bucket are thrown onto the discharge chute for discharge. This reduces the amount of silt and impurities inside the drainage pipes, while also reducing the labor required for cleaning silt and improving the convenience of the urban road flood drainage device.

[0027] 2. This urban road waterlogging drainage device, through the setting of the crushing component, when urban road waterlogging brings impurities into the water inlet tank, the rotating motor is started to drive the rotating gear to rotate. Then, the two sets of rotating gears rotate relative to each other, driving the corresponding rotating rod to rotate. This causes the high-speed rotating crushing blades on the rotating rod to cut and crush the impurities, thereby achieving the effect of crushing larger impurities, preventing large impurities from accumulating and clogging the drainage pipes, affecting normal drainage, and improving the drainage efficiency of the urban road waterlogging drainage device.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0036] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a device for draining urban road waterlogging, comprising an inlet tank 1, a sedimentation tank 2, and a slag discharge bin 3;

[0037] The inlet of the water inlet trough 1 is hinged to a cover 7, which has several filter holes 8. A pulverizing assembly is installed inside the water inlet trough 1. This pulverizing assembly effectively crushes larger impurities, preventing them from accumulating and clogging the drainage pipes, thus improving the drainage efficiency of the urban road flooding drainage system. The filter holes 8 facilitate the entry of road floodwater.

[0038] The water inlet tank 1 is connected to the upper part of the sedimentation tank 2;

[0039] The upper part of the sedimentation tank 2 is equipped with a drainage component, which serves to extract the water accumulated in the sedimentation tank 2. The bottom of the sedimentation tank 2 is connected to the slag discharge bin 3 through a conveying pipe 9. A conveying component is installed inside the conveying pipe 9.

[0040] The upper part of the slag discharge bin 3 is provided with a discharge port, and a lifting component is provided inside the slag discharge bin 3 corresponding to the discharge port. The lifting component lifts the slag inside to the discharge port for discharge.

[0041] In this design, the inlet trough 1 is located in a low-lying area. Rainwater containing leaves enters the inlet trough 1 and is crushed by the crushing component, reducing the volume of the waste and facilitating its transport. The waste then enters the sedimentation tank 2, where solid waste settles at the bottom. Water is drained to the outside through the drainage component, and the solid waste at the bottom is transported to the slag discharge bin 3 by the conveying component. The lifting component in the slag discharge bin 3 discharges the solid waste from the discharge port.

[0042] By incorporating conveying and lifting components, the system effectively reduces silt and impurities inside drainage pipes, thereby minimizing the workload of personnel cleaning up silt and improving the convenience of urban road flood drainage systems.

[0043] Combination Figure 4 As shown, the crushing assembly includes a rotating shaft 10, crushing blades 11, and a synchronous gear 12. The two sets of rotating shafts 10 are parallel to each other and rotate in cooperation with the side wall of the water inlet tank 1. The side wall of the rotating shaft 10 is provided with a plurality of crushing blades 11. The rotating shaft 10 is driven by a crushing motor 13. The ends of the two rotating shafts 10 are respectively provided with the synchronous gears 12 that mesh with each other.

[0044] Two sets of crushing blades 11 are used. Since the rotating shafts 10 are meshed by synchronous gears 12, they can rotate synchronously in opposite directions, thus improving the crushing effect.

[0045] A support base 14 is provided on the outside of the water inlet tank 1, and the crushing motor 13 is fixed to the support base 14. One of the rotating shafts 10 extends to the outside of the water inlet tank 1 and is fixed to the rotor of the crushing motor 13. This facilitates the fixing of the crushing motor 13.

[0046] The inlet tank 1 and the sedimentation tank 2 are connected by a slag discharge pipe 15, which facilitates the more independent installation of the sedimentation tank 2.

[0047] The lower part of the sedimentation tank 2 has a conical structure, which facilitates the transport of solid waste to the slag discharge bin 3 via the conveying pipe 9.

[0048] Combination Figure 3 As shown, the conveying assembly includes an auger 16 and a conveying motor 17. The auger 16 is rotatably fitted inside the conveying pipe 9, and the rotor of the conveying motor 17 is connected to the auger 16. This allows for more sufficient conveying power.

[0049] Combination Figure 5 As shown, the lifting assembly includes pulleys 18, a synchronous belt 19, and a conveyor bucket 20 disposed around the synchronous belt 19. The lower and upper parts of the slag discharge bin 3 are respectively equipped with pulleys 18, one of which is driven by a synchronous motor 21. The synchronous belt 19 is wound around the two pulleys 18. The discharge port is located on the inverted side of the conveyor bucket 20. As the conveyor bucket 20 moves upward, it scoops up the waste. When the conveyor bucket 20 turns towards the discharge port, its inertia allows it to dump the waste towards the discharge port, thus effectively removing the waste from the slag discharge bin 3. This facilitates the discharge of mud and impurities.

[0050] The slag discharge bin 3 includes a lower bin 4 and an upper bin 5 that are interconnected. Each of the lower bin 4 and the upper bin 5 is equipped with a pulley 18. The width of the upper bin 5 is adapted to the width of the conveyor hopper 20. The discharge port is located on the side wall of the upper bin 5, and a chute 6 is provided outwardly along the lower edge of the discharge port. By using an upper bin 5 that is adapted to the width of the conveyor hopper 20, it is less likely for waste to fall from the left or right side of the conveyor hopper 20. When the conveyor hopper 20 turns towards the discharge port, the waste is more easily discharged from the discharge port. Specifically, the width of the upper bin 5 being adapted to the width of the conveyor hopper 20 means that the gap between the two is controlled within 0.3-1 cm.

[0051] The drainage assembly includes a pumping pipe 22 that extends from the outside of the sedimentation tank 2 to the inside of the sedimentation tank 2. The pumping pipe 22 is equipped with a high-pressure water pump 23. This facilitates the extraction of water from the sedimentation tank 2. During the extraction process, the internal air pressure decreases, which can provide negative pressure for the waste flowing from the inlet tank 1 to the sedimentation tank 2.

[0052] The upper end of the sedimentation tank 2 is provided with a removable inspection cover 24. This facilitates maintenance in case of blockages or other problems in the sedimentation tank 2.

[0053] The beneficial effects of this solution are:

[0054] This utility model provides a device for draining urban road floodwater, which has the following beneficial effects:

[0055] 1. This urban flood drainage device, through the setting of conveying and lifting components, allows urban road floodwater mixed with silt to enter the sedimentation tank 2 through the inlet trough 1 during use, causing the silt to settle. Then, the drive motor is activated, causing the conveyor rod to rotate and carrying the silt at the bottom of the sedimentation tank 2 into the collection tank through the conveyor pipe 9. Then, the output motor is activated, causing the rotor to rotate, and the conveyor belt on the rotor drives the conveyor bucket to transport the silt and impurities at the bottom to the protective box. Using inertia, the silt and impurities in the conveyor bucket are thrown onto the discharge chute 6 for discharge, thereby reducing the amount of silt and impurities inside the drainage pipe, reducing the amount of labor required for cleaning silt, and improving the convenience of the urban road flood drainage device.

[0056] 2. This urban road waterlogging drainage device, through the setting of the crushing component, when urban road waterlogging brings impurities into the water inlet tank 1 during use, the rotating motor is started to drive the rotating gear to rotate, and then the two sets of rotating gears rotate relative to each other, driving the corresponding rotating rod to rotate, so that the high-speed rotating crushing blades on the rotating rod cut and crush the impurities, thereby achieving the effect of crushing larger impurities, preventing large impurities from accumulating and clogging the drainage pipes, affecting normal drainage, and improving the drainage efficiency of the urban road waterlogging drainage device.

[0057] It should be noted that this solution is only applicable to a few road sections with a particularly large amount of solid waste such as leaves, or road sections where a lot of solid waste such as leaves requires automated processing. It can significantly reduce the possibility of congestion on such road sections, but due to its mechanical structure and cost issues, it is not applicable to all road sections.
