Abstract
Description
Technical Field
[0001] This application belongs to the field of municipal equipment technology, specifically relating to a rainwater harvesting-based urban village flooding mitigation device. Background Technology
[0002] In the specific environment of urban villages, due to their relatively weak infrastructure, the drainage system is often overwhelmed when faced with heavy rainfall, which can easily lead to waterlogging.
[0003] Existing technologies typically alleviate urban flooding in villages by collecting rainwater. This involves collecting runoff from roads and rooftops to reduce pressure on drainage systems. Following this, the collected rainwater undergoes preliminary sedimentation treatment to allow the relatively clean water to flow into storage tanks, thus enabling rainwater resource recycling.
[0004] The inventors discovered that existing flood mitigation devices typically rely on gravity to allow impurities in rainwater to settle naturally. This sedimentation process takes a long time, resulting in rainwater not being able to drain into the storage tank in a timely manner, which affects the stability of the flood mitigation process. Utility Model Content
[0005] This application provides a rainwater harvesting-based urban village flood mitigation device, which aims to improve the efficiency of treating impurities in rainwater to ensure the stability of the flood mitigation process.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0007] A rainwater harvesting-based flood mitigation device for urban villages is provided, comprising:
[0008] A housing for fixing to the outside of a water storage tank; the housing has an upward-facing cavity for holding rainwater, and a drain outlet communicating with the cavity is provided on the side facing the water storage tank; a filter screen is fixedly installed at the drain outlet, and a drain pipe communicating with the water storage tank is also connected thereto.
[0009] A push plate is slidably disposed within the receiving cavity along the axial direction of the drain outlet and is driven by a linear drive component for moving it; the bottom surface of the push plate is in contact with the bottom surface of the receiving cavity, and its two ends are respectively in contact with the two sides of the receiving cavity, so that when the push plate moves, it can push impurities in the rainwater and impurities attached to the sides and bottom of the receiving cavity away from the drain outlet; and
[0010] A sweeping component is disposed at the drain outlet and located on the side of the filter screen facing the receiving cavity, to push the impurities attached to and accumulated on the filter screen to the outside of the drain outlet.
[0011] In one possible implementation, the linear drive component includes:
[0012] A drive screw is rotatably disposed within the receiving cavity, its axis parallel to the axis of the drain outlet, and the drive screw is drively connected to a first rotary motor for driving its rotation; and
[0013] The transmission nut is fixedly mounted on the push plate and threadedly connected to the transmission screw.
[0014] In one possible implementation, the push plate has an upwardly extending protrusion with a mounting hole extending axially along the drive screw, and the drive nut is fixedly fitted into the mounting hole.
[0015] In one possible implementation, the sweeping component includes:
[0016] A swing arm is hinged to the inner wall of the receiving cavity above the drain outlet; the swing arm has a connecting rod coaxially arranged with its hinge axis, passing through the housing and extending outwards, and the extended end of the connecting rod is coaxially connected to a transmission gear; and
[0017] A transmission rack is slidably connected to the outer side of the housing in the horizontal direction, meshes with the transmission gear, and is connected to a reciprocating drive component for driving its reciprocating movement.
[0018] In one possible implementation, the reciprocating drive component includes:
[0019] Driven arm, one end of which is hinged to the transmission rack, and the hinge axis is parallel to the axis of the transmission gear; and
[0020] The second rotating motor is fixedly installed on the outer side of the housing, and its power output axis is parallel to the hinge axis of the driven arm; the power output end of the second rotating motor is connected to a transmission arm, and the swing end of the transmission arm is hinged to the swing end of the driven arm.
[0021] When the second rotating motor is started, the transmission arm rotates around the power output shaft of the second rotating motor to drive the hinge end of the driven arm and the transmission rack to reciprocate in the horizontal direction.
[0022] In one possible implementation, a control valve is connected to the drain pipe.
[0023] In one possible implementation, a guide rod is fixedly disposed inside the receiving cavity;
[0024] The axial direction of the guide rod is parallel to the axial direction of the drain outlet and is slidably connected to the push plate.
[0025] In one possible implementation, the bottom surface of the receiving cavity has a recessed portion on the side away from the drain outlet, and the recessed portion is used to accommodate impurities pushed and settled by the pusher plate.
[0026] In one possible implementation, the urban village flooding mitigation device further includes:
[0027] A rotating roller is rotatably mounted on the side of the push plate facing away from the drain outlet. Its rotational axis is parallel to the horizontal direction and perpendicular to the axis of the drain outlet. Furthermore, the rotating roller is driven by an adjusting drive component for rotating it.
[0028] Multiple propellers are spaced apart on the rotating roller along the axial direction of the rotating roller, and the propellers of any two of them are arranged in parallel to each other.
[0029] When the pusher plate moves, each of the pusher blades can rotate and agitate the rainwater to change the flow direction and velocity distribution of the rainwater on the side of the pusher plate facing away from the drain outlet.
[0030] In one possible implementation, the adjustment drive component includes:
[0031] The transmission worm gear is coaxially connected to the rotating roller; and
[0032] The transmission worm gear is rotatably mounted on the push plate in the up-down direction. It is connected to the transmission worm wheel, and the transmission worm gear is connected to a third rotary motor for driving its rotation.
[0033] In this embodiment, rainwater is centrally transferred through a receiving cavity. When the amount of rainwater entering is large, the rainwater in the receiving cavity needs to be discharged into a storage tank in a timely manner through a drain pipe. During the process of rainwater flowing into the storage tank, a filter screen can prevent impurities from entering the storage tank, and a sweeping component can prevent impurities from clogging the filter screen. Furthermore, a linear drive component moves a push plate, causing impurities in the rainwater and those adhering to the sides and bottom of the receiving cavity to move away from the drain outlet, thereby promptly preventing impurities from affecting the drained liquid.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0051] Please refer to the following: Figures 1 to 10 The present application describes a rainwater harvesting-based urban village flood mitigation device. The rainwater harvesting-based urban village flood mitigation device proposed in this application includes a housing 1, a pusher plate 2, and a sweeping assembly 3.
[0052] The housing 1 is fixed to a horizontal surface outside the water storage tank. The housing 1 has an upward-facing receiving cavity 11 for collecting rainwater, which is connected to a rainwater drainage mechanism. A drain outlet 12, connected to the receiving cavity 11, is provided on the side of the housing 1 facing the water storage tank. A filter screen 121, coaxially arranged with the drain outlet 12, is fixedly installed inside the drain outlet 12, and a drain pipe 122, connected to the water storage tank, is also provided to facilitate the transfer of liquid from the receiving cavity 11 to the water storage tank.
[0053] The push plate 2 is slidably disposed in the receiving cavity 11 along the axial direction of the drain outlet 12, and is driven by a linear drive component 4 for moving it. On this basis, the bottom surface of the push plate 2 is in contact with the bottom surface of the receiving cavity 11, and both ends are respectively in contact with the two sides of the receiving cavity 11, so that when the push plate 2 moves, it can push the impurities in the rainwater and the impurities attached to the sides and bottom surface of the receiving cavity 11 away from the drain outlet 12.
[0054] The sweeping component 3 is located at the drain outlet 12 and on the side of the filter screen 121 facing the receiving cavity 11. It pushes the impurities attached to and accumulated on the filter screen 121 to the outside of the drain outlet 12. On the one hand, it works with the filter screen 121 to prevent impurities from entering the drain pipe 122, and on the other hand, it ensures drainage efficiency.
[0055] In this embodiment, rainwater is centrally transferred through the containment cavity 11. However, when the amount of rainwater entering the containment cavity 11 is large, the rainwater in the containment cavity 11 needs to be discharged into the water storage tank in a timely manner through the drain pipe 122.
[0056] During the process of rainwater being discharged into the water storage tank, the filter screen 121 can prevent impurities from entering the water storage tank, and the sweeping component 3 can prevent impurities from clogging the filter screen 121.
[0057] Based on this, by driving the push plate 2 to move through the linear drive component 4, the impurities in the rainwater and the impurities attached to the sides and bottom of the receiving cavity 11 can be moved away from the drain outlet 12, thereby timely avoiding the impurities from affecting the drained liquid.
[0058] The rainwater harvesting-based urban village flood mitigation device provided in this embodiment can improve the efficiency of removing impurities from rainwater compared with existing technologies, thereby ensuring the stability of the flood mitigation process.
[0059] In some embodiments, such as Figure 9 As shown, the linear drive component 4 includes a transmission screw 41 and a transmission nut 42.
[0060] The transmission screw 41 is rotatably disposed in the receiving cavity 11, and its axial direction is parallel to the axial direction of the drain outlet 12. The transmission screw 41 is connected to a first rotating motor 411 for driving its rotation.
[0061] The transmission nut 42 is fixedly mounted on the push plate 2 and is threadedly connected to the transmission screw 41.
[0062] In some embodiments, such as Figure 9 As shown, the push plate 2 has an upwardly extending protrusion 21, and the protrusion 21 has a mounting hole 211 that passes through the axial direction of the transmission screw 41. The transmission nut 42 is fixedly embedded in the mounting hole 211 to achieve a recessed installation of the transmission nut 42 relative to the protrusion 21.
[0063] In some embodiments, such as Figure 4 and Figure 5 As shown, the sweeping assembly 3 includes a swing arm 31 and a transmission rack 32.
[0064] The swing arm 31 is hinged to the inner wall of the receiving cavity 11 above the drain outlet 12; based on this, the swing arm 31 has a connecting rod 311 that is coaxially arranged with its hinge axis, passes through the box body 1 and extends out, and the extended end of the connecting rod 311 is coaxially connected to a transmission gear 312.
[0065] The transmission rack 32 is slidably connected to the outer side of the housing 1 in the horizontal direction. It meshes with the transmission gear 312, and the transmission rack 32 is connected to a reciprocating drive component 5 for driving its reciprocating movement.
[0066] In some embodiments, such as Figure 3 and Figure 4 As shown, the reciprocating drive component 5 includes a driven arm 51 and a second rotary motor 52.
[0067] Driven arm 51 is disposed on the upper side of transmission rack 32, and one end of driven arm 51 is hinged to transmission rack 32, with its hinge axis parallel to the axis of transmission gear 312.
[0068] The second rotary motor 52 is fixedly mounted on the outer side of the housing 1, and its power output axis is parallel to the hinge axis of the driven arm 51. Based on this, the power output end of the second rotary motor 52 is connected to a transmission arm 521 that extends radially outward, and the swing end (i.e. its extension end) of the transmission arm 521 is hinged to the swing end of the driven arm 51.
[0069] By adopting the above technical solution, when the second rotating motor 52 is started, the transmission arm 521 rotates around the power output shaft of the second rotating motor 52, so as to drive the hinge end of the driven arm 51 and the transmission rack 32 to move back and forth in the horizontal direction.
[0070] In some embodiments, such as Figure 1 As shown, a control valve 7 is connected to the drain pipe 122; in actual use, the drain pipe 122 can be opened or closed by the control valve 7, so as to control the timing and duration of drainage of the drain pipe 122.
[0071] In some embodiments, such as Figure 5 and Figure 10 As shown, a guide rod 13 is fixedly installed inside the receiving cavity 11; in this embodiment, there are two guide rods 13, and the two guide rods 13 are arranged side by side in the horizontal direction. The axial direction of each guide rod 13 is parallel to the axial direction of the drain outlet 12, and both are slidably connected to the aforementioned push plate 2 to limit the sliding position of the push plate 2.
[0072] In some embodiments, such as Figure 10 As shown, the bottom surface of the receiving cavity 11 has a recessed portion 14 on the side away from the drain outlet 12, and the recessed portion 14 is used to receive impurities pushed and settled by the pusher plate 2.
[0073] Meanwhile, since the sinking part 14 is set below the bottom surface of the receiving cavity 11, when impurities move to the sinking part 14 along with the rainwater, the impurities will settle faster as the rainwater converges downwards.
[0074] In some embodiments, such as Figures 5 to 8 As shown, the urban village flooding mitigation device also includes a rotating roller 8 and multiple propellers 81.
[0075] The rotating roller 8 is rotatably disposed on the side of the push plate 2 facing away from the drain outlet 12. Its rotation axis is parallel to the horizontal direction and perpendicular to the axis of the drain outlet 12. Furthermore, the rotating roller 8 is connected to an adjustment drive component 9 for driving its rotation.
[0076] Multiple propellers 81 are spaced apart on the rotating roller 8 along the axial direction of the rotating roller 8, and the propellers 81 of any two of them are arranged parallel to each other.
[0077] By adopting the above technical solution, during the movement of the pusher plate 2, each pusher blade 81 can rotate and agitate the rainwater, thereby changing the flow direction and speed distribution of the rainwater on the side of the pusher plate 2 facing away from the drain outlet 12, thus forming a reasonable water flow trajectory, effectively avoiding dead zones in the water flow, and ensuring that the water in the receiving cavity 11 is in an effective flow state.
[0078] In some embodiments, such as Figure 6 and Figure 7 As shown, the adjustment drive component 9 includes a transmission worm gear 91 and a transmission worm 92.
[0079] The transmission worm gear 91 is coaxially connected to the rotating roller 8 and is arranged to avoid each propeller 81.
[0080] The transmission worm 92 is rotatably mounted on the push plate 2 in the up-down direction and is connected to the transmission worm wheel 91; specifically, the push plate 2 has a groove on the side facing the rotating roller 8, and the transmission worm 92 is embedded in this groove.
[0081] In this embodiment, the transmission worm 92 is connected to a third rotary motor 921 for driving its rotation; when the third rotary motor 921 drives the transmission worm 92 to rotate, the transmission worm wheel 91 rotates synchronously to drive the rotation of the rotating roller 8, thereby adjusting the orientation of the propeller 81.
[0082] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
