Description

Technical Field

[0001] This utility model belongs to the field of rainwater harvesting technology, specifically relating to a hard paving rainwater harvesting system. Background Technology

[0002] When rain falls on a city, timely collection of rainwater can prevent rainwater from being wasted through drainage. At the same time, the collected rainwater can be treated and used for needs such as toilet flushing, cleaning, and irrigation, alleviating the problem of urban water shortage.

[0003] Chinese patent CN221255094U discloses a permeable pavement structure for roads. This design includes a soil base layer, a permeable pavement, a permeable layer, and drainage channels. A water-absorbing membrane is laid on the soil base layer, and a flexible mortar is applied over the membrane. The permeable layer is positioned above the flexible mortar. Drainage channels are located on both sides of the permeable pavement, with the top of the channels flush with the top of the soil base layer. Support walls are installed on the vertical sidewalls of both ends of the drainage channels, and permeable holes are formed on the vertical sidewalls of these support walls, penetrating both ends of the support walls. The top of the support walls is lower than the permeable pavement. This design allows rainwater to pass through the permeable pavement and permeable layer before flowing into the drainage channels.

[0004] In some urban areas, there is a need to support vehicles. When laying permeable pavements, existing technologies generally use permeable bricks, permeable concrete, or bricks with permeable holes. However, these materials have low strength, which makes it difficult for the above solutions to meet the requirements of supporting vehicles when collecting rainwater. Utility Model Content

[0005] The present invention aims to provide a hard-paved rainwater harvesting system to solve the problem of vehicles being able to carry rainwater when the above-mentioned solutions are in use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hard-surfaced rainwater harvesting system, installed on a subgrade layer, includes a U-shaped drainage ditch and a manhole. The U-shaped drainage ditch is placed on the subgrade layer, and an installation frame is fixedly installed on the top of the U-shaped drainage ditch. A slotted drainage ditch cover is fixedly installed on the top of the installation frame. Reinforced concrete layers are provided on the outer side of the U-shaped drainage ditch and on the top of the slotted drainage ditch cover. The manhole is located on one side of the end of the U-shaped drainage ditch and has an inner cavity. A platform is provided on the inner wall of the inner cavity. The inner cavity above the platform is connected to the U-shaped drainage ditch through a drain pipe. A intercepting frame is slidably installed in the inner cavity above the platform. An overflow pipe is connected to the inner wall of the inner cavity below the intercepting frame.

[0008] The principle and effects of this technical solution:

[0009] In its initial state, the intercepting frame is placed on the platform, and the output end of the drain pipe is located above the intercepting frame. When rainfall occurs, rainwater on the surface of the reinforced concrete layer flows into the U-shaped drainage ditch through the gap drainage ditch cover, and then flows into the inner cavity through the drain pipe. When the rainwater passes through the intercepting frame, the intercepting frame intercepts impurities mixed in with the rainwater. When the water level in the inner cavity overflows the lower edge of the overflow pipe, this part of the rainwater flows into the municipal rainwater pipe through the overflow pipe. When a vehicle drives over this device, the foundation soil layer, the U-shaped drainage pipe, the mounting frame, and the gap drainage ditch cover provide support for the adjacent components above in sequence.

[0010] With the above-mentioned configuration, a reinforced concrete layer is installed above the mounting frame and the gap drainage ditch cover to improve the structural strength of the device, enabling it to carry vehicles while collecting rainwater. By installing a sewage interception frame, the collected rainwater can be filtered, improving the water quality of the collected rainwater.

[0011] In this utility model, the inner wall of the inner cavity is provided with a groove above the shelf, the output end of the drain pipe extends through the inner wall of the groove, a crossbar is fixedly provided in the groove below the drain pipe, and a sludge intercepting plate is rotatably sleeved on the crossbar.

[0012] The principle and effects of this technical solution:

[0013] When the intercepting frame is placed on the shelf, one side wall of the intercepting plate contacts the bottom wall of the groove, and the intercepting plate is located above the intercepting frame. When it is necessary to clean the impurities in the intercepting frame, lift the intercepting frame upwards. The top of the intercepting frame pushes the intercepting plate to rotate. When the top of the intercepting frame moves above the crossbar, the other side wall of the intercepting plate fits against the inner side wall of the groove. At this time, the intercepting plate intercepts the impurities in the rainwater into the drain pipe. After the impurities in the intercepting frame are cleaned, move it downwards to the shelf. The rainwater in the drain pipe pushes the intercepting plate to rotate, and the impurities intercepted by the intercepting plate fall into the intercepting frame.

[0014] With the above-mentioned design, the intercepting plate is rotated within the groove, which prevents impurities from falling into the inner cavity below the intercepting frame during the lifting process, thus ensuring the purification effect of the device on rainwater.

[0015] In this invention, a protrusion is fixedly provided on the top of the inner sidewall of the intercepting frame. This design allows maintenance personnel to easily lift the intercepting frame.

[0016] In this utility model, the top of the outer wall of the intercepting frame is provided with a sliding groove extending to the protrusion, and the end wall of the sliding groove is provided with a pin hole that penetrates to the inner wall of the protrusion. A limiting block is slidably arranged in the sliding groove, and a pin rod that slides through the pin hole is fixedly arranged on the side wall of the limiting block.

[0017] In this invention, the outer sleeve of the pin is provided with a tension spring, and the two ends of the tension spring are respectively connected to the end of the pin and the protrusion.

[0018] The principle and effects of this technical solution:

[0019] When the intercepting frame is placed in the inner cavity, the inner wall of the inner cavity pushes the slider to move into the chute. At this time, the tension spring has elasticity. When the intercepting frame is lifted up until the bottom wall of the chute is flush with the top surface of the inspection well, the tension spring pulls the pin to move deeper into the chute. When the end of the pin presses against the protrusion and tightens the tension spring, one end of the limiting block is above the inspection well, and the other end is inside the chute.

[0020] With the above settings, the intercepting frame can be automatically hung on the top of the inspection well when it is lifted, making it convenient for maintenance personnel to clean the impurities inside the intercepting frame.

[0021] In this invention, the intercepting frame has a vertically penetrating channel. A filter screen is fixedly installed at the bottom of the channel, and a through hole is provided in the middle of the filter screen. A filter cover is fixedly installed on the top of the filter screen around the through hole. This design allows rainwater to seep downwards through the side wall of the filter cover and the through hole, even when impurities accumulate on the top of the filter screen. This reduces the frequency of manual cleaning of the intercepting frame and saves manpower.

[0022] In this invention, a manhole cover is rotatably mounted on the top of the inspection well. This design effectively shields the inner cavity, preventing impurities from falling into it from the top and ensuring the device's effectiveness in purifying rainwater. Attached Figure Description

[0030] As attached Figure 1-4 As shown, this utility model discloses a hard-paved rainwater collection system, which is installed on the base soil layer 21 and includes a U-shaped drainage ditch 10 and an inspection well 40. The U-shaped drainage ditch 10 is placed on the base soil layer 21, and an installation frame 30 is fixedly installed on the top of the U-shaped drainage ditch 10. The installation frame 30 is welded from square steel pipes, and a slotted drainage ditch cover plate 31 is fixedly installed on the top of the installation frame 30. Reinforced concrete layers 22 are provided on the outer side of the U-shaped drainage ditch 10 and the top of the slotted drainage ditch cover plate 31. The inspection well 40 is located on one side of the end of the U-shaped drainage ditch 10 and has an inner cavity 41. A platform 42 is provided on the inner side wall of the inner cavity 41. The inner cavity 41 above the platform 42 is connected to the U-shaped drainage ditch 10 through a drainage pipe 50. A intercepting frame 60 is slidably installed in the inner cavity 41 above the platform 42. An overflow pipe 70 is connected to the inner side wall of the inner cavity 41 below the intercepting frame 60.

[0031] In this embodiment, the inner wall of the inner cavity 41 is provided with a groove 43 above the platform 42, the output end of the drain pipe 50 extends through the inner end wall of the groove 43, a crossbar 44 is fixedly provided in the groove 43 below the drain pipe 50, and a dirt intercepting plate 45 is rotatably sleeved on the outside of the crossbar 44.

[0032] In this embodiment, a protrusion 61 is fixedly provided on the top of the inner sidewall of the dirt interception frame 60.

[0033] In this embodiment, the top of the outer side wall of the intercepting frame 60 is provided with a groove 62 extending to the protrusion 61, and the end wall of the groove 62 is provided with a pin hole 63 that extends to the inner side wall of the protrusion 61. A limiting block 64 is slidably arranged in the groove 62, and a pin 65 that slides through the pin hole 63 is fixedly arranged on the side wall of the limiting block 64.

[0034] In this embodiment, a tension spring 66 is provided on the outer sleeve of the pin 65, and the two ends of the tension spring 66 are respectively connected to the end of the pin 65 and the protrusion 61.

[0035] In this embodiment, the trap frame 60 has a vertically penetrating channel, a filter screen 67 is fixedly installed at the bottom of the channel, a through hole is provided in the middle of the filter screen 67, and a filter cover 68 is fixedly installed on the top of the filter screen 67 around the through hole.

[0036] In this embodiment, a manhole cover (not shown in the figure) is rotatably provided on the top of the inspection well 40, and the manhole cover is used to cover the inner cavity 41.

[0037] The specific implementation process is as follows:

[0038] In the initial state, the intercepting frame 60 is placed on the platform 42, and the output end of the drain pipe 50 is located above the intercepting frame 60. When it rains, rainwater on the surface of the reinforced concrete layer 22 flows into the U-shaped drainage ditch 10 through the gap drainage ditch cover 31, and then flows into the inner cavity 41 through the drain pipe 50. When the rainwater passes through the intercepting frame 60, the intercepting frame 60 intercepts the impurities mixed in with the rainwater. When the water surface in the inner cavity 41 overflows the lower edge of the overflow pipe 70, this part of the rainwater flows into the municipal rainwater pipe through the overflow pipe 70. When a vehicle drives over this device, the foundation soil layer 21, the U-shaped drainage pipe 50, the mounting frame 30 and the gap drainage ditch cover 31 provide support for the adjacent components above in sequence.

[0039] When the intercepting frame 60 is placed on the shelf 42, one side wall of the intercepting plate 45 contacts the bottom wall of the groove 43, the intercepting plate 45 is in a horizontal state, and the intercepting plate 45 is above the intercepting frame 60. When it is necessary to clean the impurities in the intercepting frame 60, lift the intercepting frame 60 upwards. The top of the intercepting frame 60 pushes the intercepting plate 45 to rotate. When the top of the intercepting frame 60 moves above the crossbar 44, the other side wall of the intercepting plate 45 is in contact with the inner end wall of the groove 43. At this time, the intercepting plate 45 intercepts the impurities in the rainwater into the drain pipe 50. After the impurities in the intercepting frame 60 are cleaned, move it downwards to be placed on the shelf 42. The rainwater in the drain pipe 50 pushes the intercepting plate 45 to rotate, and the impurities intercepted by the intercepting plate 45 fall into the intercepting frame 60.

[0040] When the intercepting frame 60 is placed in the inner cavity 41, the inner wall of the inner cavity 41 pushes the slider to move into the slide groove 62. At this time, the tension spring 66 has elasticity. When the intercepting frame 60 is lifted up until the bottom wall of the slide groove 62 is flush with the top surface of the inspection well 40, the tension spring 66 pulls the pin 65 to move in the direction of going deeper into the slide groove 62. When the end of the pin 65 presses the tension spring 66 with the protrusion 61, one end of the limiting block 64 is located above the inspection well 40, and the other end is located in the slide groove 62.
