Description

Technical Field

[0001] This invention relates to the field of rainwater harvesting well technology, specifically a novel rainwater harvesting well. Background Technology

[0002] As a key component of sponge city stormwater management, the development of rainwater harvesting wells reflects a shift in concepts from engineering drainage to ecological water management. Its technological prototype originated from early European rain garden designs, achieving rainwater retention and natural infiltration through a tiered structure. Modern improved harvesting wells adopt modular assembly technology, with internal sedimentation zones and filtration units that can effectively separate suspended solids in rainwater. Combined with intelligent diversion devices, they can automatically identify and intercept rainwater with heavier initial pollution. This structure avoids the scouring and pollution caused by traditional pipe networks directly discharging rainwater into rivers, and also reduces the pressure on urban drainage systems by delaying peak runoff.

[0003] Existing rainwater harvesting wells typically have internal filters to intercept impurities such as leaves, gravel, and plastic products washed in by rainwater. Under normal rainfall conditions, the filters effectively separate solids and liquids. However, during heavy rainfall, the sudden increase in water flow force carries away a large amount of suspended matter and sediment, causing a layer of silt composed of fibrous debris and particulate matter to quickly form on the filter surface. This causes some lightweight debris to be repeatedly adsorbed onto the edges of the mesh under turbulent flow, which easily leads to clogging of the filter and reduces the speed at which the rainwater harvesting well collects rainwater.

[0004] In view of this, we propose a new type of rainwater collection well. Summary of the Invention

[0005] The purpose of this invention is to provide a novel rainwater harvesting well to solve the problem mentioned in the background art: when encountering heavy rainfall, the instantaneous increase in water flow impact force will carry a large amount of suspended matter and sediment, causing the filter screen surface to quickly form a silt layer composed of fibrous debris and particulate matter. Under the action of turbulence, some lightweight garbage is repeatedly adsorbed onto the edge of the mesh, which easily leads to the clogging of the filter screen and thus reduces the rainwater harvesting speed of the rainwater harvesting well. To achieve the above objectives, the present invention provides the following technical solution: a novel rainwater collection well, comprising a filter frame, a collection frame fixedly connected to the bottom of the filter frame, a partition plate fixedly connected inside the filter frame, two support blocks fixedly connected to the front side of the filter frame, a motor fixedly connected to the front side of the right support block, a reciprocating screw fixedly connected to one end of the rotating shaft of the motor, one end of the reciprocating screw rotatably connected to the side of the left support block, a scraping mechanism for cleaning impurities movably sleeved on the side of the reciprocating screw, and two rectangular grooves opened on the lower side of the inner wall of the filter frame, with a cleaning mechanism for filtering impurities slidably arranged inside the two rectangular grooves.

[0006] Preferably, the scraping mechanism includes an L-shaped bar, the vertical rod of which is movably sleeved on the side of a reciprocating screw. A long groove is provided on the front side of the filter frame, the interior of which slides into the interior of the horizontal bar of the L-shaped bar. A 30° bevel is provided on both the left and right sides of the bottom of the horizontal bar of the L-shaped bar, and the bottom of the horizontal bar slides into the top of the partition plate. Through grooves are provided on both the left and right sides of the rear side of the filter frame. The 30° bevel design of the L-shaped horizontal bar not only reduces movement resistance but also produces a cutting effect similar to a blade, significantly removing organic matter such as leaves and algae that adhere to the surface of the partition plate after being soaked by rainwater. The sliding fit between the long groove and the horizontal bar uses a high-density polyethylene wear-resistant bushing, effectively reducing friction loss. The inclined design of the through groove, combined with the movement trajectory of the L-shaped bar, forms a directional conveying channel, allowing impurities to be efficiently collected under the combined action of gravity and scraping force.

[0007] Preferably, two C-shaped plates are slidably connected inside the channel. The bottom of the inner wall of the channel is beveled, and the top of the horizontal plate of the C-shaped plate is on the same parallel plane as the bottom of the inner wall of the channel. A T-shaped scraper is fixedly connected to the rear side of the two horizontal plates of the two C-shaped plates on opposite sides. The C-shaped plates can collect leaves and other impurities that move into the channel. When the impurities are full, the C-shaped plates can be pulled outward to clean the leaves and other impurities inside. At the same time, the two C-shaped plates can drive the T-shaped scraper to move forward and scrape off some gravel and other impurities on the upper side of the filter plate. The inclined channel can collect leaves and other impurities.

[0008] Preferably, the cleaning mechanism includes a filter plate, which is slidably connected to the upper side of the inner wall of two rectangular grooves. Four compression springs are fixedly connected to the bottom of the filter plate, and the bottom ends of the compression springs are fixedly engaged with the lower side of the inner wall of the rectangular grooves. The vertical plate of the T-shaped scraper is made of hard rubber and is slidably engaged with the top of the filter plate. Two square grooves are opened on the left and right sides of the front side of the filter frame. Two support plates are slidably connected inside the square grooves. The rear side of the support plate is fixedly connected to the front side of the filter plate. The T-shaped scraper can scrape off some small stones from the upper side of the filter plate. When the abutment block squeezes the support plate, it can drive the filter plate to move downward and compress the compression springs, causing the filter plate to vibrate. This reduces the possibility of stones and other impurities getting stuck in the holes on the side of the filter plate, thereby ensuring the speed at which the filter plate filters rainwater.

[0009] Preferably, the reciprocating screw has a stop block fixedly connected to both the left and right sides. The sides of the stop block are rounded and slide against the top of the support plate. The rounded stop block generates less friction when it contacts the support plate.

[0010] Preferably, the diameter of the through hole on the top surface of the filter plate is half the diameter of the through hole on the top surface of the partition plate. The filter plate can block small stones and other impurities that flow into the filter frame with rainwater, while the partition plate can block impurities such as leaves and plastic. The dual filtration by the filter plate and the partition plate further enhances the filtration effect on impurities such as leaves and gravel that flow with rainwater.

[0011] Preferably, the inner wall of the channel has a plurality of water outlet holes on its side. The plurality of water outlet holes are equidistantly arranged in a straight line on the lower side of opposite sides of the inner wall of the two channels. The water outlet holes can quickly discharge some of the rainwater flowing to the inner wall of the channel, reducing the possibility of bacteria growing inside the channel.

[0012] Preferably, the collecting frame is an isosceles trapezoid with a fixing groove at the bottom. A protective frame is fixedly connected to the front of the filter frame. The protective frame can protect the motor and the reciprocating screw, preventing damage or jamming and ensuring the overall service life of the motor and the reciprocating screw.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, impurities such as leaves are filtered through a partition plate. A motor drives a reciprocating screw to rotate, and a long groove limits the L-shaped strip. As the screw rotates, it causes the L-shaped strip to move back and forth on the top of the partition plate, quickly moving the leaves and other impurities into the through groove and collecting them through a C-shaped plate. Some of the rainwater that enters the through groove can be quickly discharged through the outlet hole, thus quickly cleaning the leaves and other impurities on the top of the partition plate. This reduces the possibility of clogging in the rainwater collection well and ensures the speed of rainwater collection.

[0014] In this invention, a motor drives a reciprocating screw and two contact blocks to rotate. Simultaneously, a rectangular groove limits the filter plate, causing the contact blocks to contact the filter plate as they rotate. This causes the filter plate to move downwards and compress the compression spring. When the contact blocks rotate to release their contact with the filter plate, the filter plate resets via the compression spring, resulting in continuous vibration of the filter plate. This vibration causes the filter plate to shake out some of the small stones flowing to the upper side and vibrate them out of the holes inside the filter plate, thereby further increasing the speed at which the rainwater collection well collects and filters rainwater.

[0015] In this invention, once the top of the C-shaped plate is full of leaves and other impurities, the two C-shaped plates are moved backward, causing the leaves and other impurities on their upper sides to move out and be removed. At the same time, as the C-shaped plates move, the T-shaped scraper moves forward, and the vertical plate of the T-shaped scraper scrapes off some small stones and other impurities from the top of the filter plate, thereby quickly cleaning the top of the filter plate.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 9 The present invention provides a technical solution: a novel rainwater collection well, comprising a filter frame 1, a collection frame 2 fixedly connected to the bottom of the filter frame 1, a partition plate 3 fixedly connected inside the filter frame 1, two support blocks 4 fixedly connected to the front side of the filter frame 1, a motor 5 fixedly connected to the front side of the right support block 4, a reciprocating screw 6 fixedly connected to one end of the rotating shaft of the motor 5, one end of the reciprocating screw 6 rotatably connected to the side of the left support block 4, a scraping mechanism 7 for cleaning impurities movably sleeved on the side of the reciprocating screw 6, and two rectangular grooves 8 opened on the lower side of the inner wall of the filter frame 1, with a cleaning mechanism 9 for filtering impurities slidably arranged inside the two rectangular grooves 8.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, the scraping mechanism 7 includes an L-shaped bar 701. The vertical rod of the L-shaped bar 701 is movably sleeved on the side of the reciprocating screw 6. A long groove 101 is provided on the front side of the filter frame 1. The interior of the long groove 101 is slidably engaged with the interior of the horizontal bar of the L-shaped bar 701. A 30° bevel is provided on both the left and right sides of the bottom of the horizontal bar of the L-shaped bar 701. The bottom of the horizontal bar of the L-shaped bar 701 is slidably engaged with the top of the partition plate 3. Through grooves 702 are provided on both the left and right sides of the rear side of the filter frame 1. The bottom of the inclined L-shaped bar 701 is relatively sharp, which makes it easy to scrape the leaves and other impurities that have been wetted by rainwater and adsorbed on the upper side of the partition plate 3 into the through groove 702 for collection.

[0021] In this embodiment, as Figure 1 , Figure 2, Figure 3 , Figure 4 , Figures 5 to 9 As shown, two C-shaped plates 703 are slidably connected inside the channel 702. The bottom of the inner wall of the channel 702 is beveled, and the top of the horizontal plate of the C-shaped plate 703 is on the same parallel plane as the bottom of the inner wall of the channel 702. T-shaped scrapers 704 are fixedly connected to the rear side of the two horizontal plates of the two C-shaped plates 703 on opposite sides. The C-shaped plates 703 can collect leaves and other impurities that move into the channel 702. When the impurities are full, the C-shaped plates 703 can be pulled outward to clean the leaves and other impurities inside. At the same time, the two C-shaped plates 703 can drive the T-shaped scrapers 704 to move forward and scrape off some stones and other impurities on the upper side of the filter plate 901. The inclined channel 702 can collect leaves and other impurities.

[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, the cleaning mechanism 9 includes a filter plate 901, which is slidably connected to the upper side of the inner wall of two rectangular grooves 8. Four compression springs 902 are fixedly connected to the bottom of the filter plate 901, with the bottom ends of the springs 902 fixedly engaged with the lower side of the inner wall of the rectangular grooves 8. The vertical plate of the T-shaped scraper 704 is made of hard rubber, and the vertical plate of the T-shaped scraper 704 is slidably engaged with the top of the filter plate 901. Two square grooves 102 are opened on the left and right sides of the front side of the filter frame 1. The internal sliding connection of 02 has two support plates 103. The rear side of the support plate 103 is fixedly connected to the front side of the filter plate 901. The T-shaped scraper 704 can scrape down some small stones on the upper side of the filter plate 901. When the contact block 601 squeezes the support plate 103, it can drive the filter plate 901 to move downward and compress the compression spring 902, causing the filter plate 901 to vibrate, reducing the possibility of stones and other impurities getting stuck in the holes on the side of the filter plate 901.

[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, abutment blocks 601 are fixedly connected to both the left and right sides of the reciprocating screw 6. The sides of the abutment blocks 601 are rounded, and the sides of the abutment blocks 601 slide with the top of the support plate 103. The friction generated when the sides of the abutment blocks 601 with rounded corners abut against the support plate 103 is small.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, the diameter of the through hole on the top surface of the filter plate 901 is half the diameter of the through hole on the top surface of the partition plate 3. The filter plate 901 can block small stones and other impurities that flow into the filter frame 1 with rainwater, while the partition plate 3 can block leaves, plastic and other impurities.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, several water outlet holes 705 are provided on the side of the inner wall of the channel 702. The several water outlet holes 705 are equidistantly arranged in a straight line on the lower side of the opposite side of the inner wall of the two channels 702. The water outlet holes 705 can quickly discharge some of the rainwater flowing to the inner wall of the channel 702.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, the shape of the collection frame 2 is an isosceles trapezoid, and the bottom of the collection frame 2 is provided with a fixing groove. The front side of the filter frame 1 is fixedly connected to the protective frame 104, which can protect the motor 5 and the reciprocating screw 6.

[0027] The method of use and advantages of this invention: The working process of this novel rainwater collection well is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figures 8 to 9 As shown, when the rain is heavy and the turbulent rainwater carries leaves and other impurities into the filter frame 1, the leaves and other impurities are first filtered by the partition plate 3. At this time, the rotating shaft of the motor 5 drives the reciprocating screw 6 on its side to rotate. The L-shaped bar 701 is limited by the long groove 101, so that the reciprocating screw 6 drives the L-shaped bar 701 to move back and forth continuously on the top of the partition plate 3 when it rotates. This quickly moves the leaves and other impurities into the through groove 702 and collects them through the C-shaped plate 703. Some of the rainwater that enters the through groove 702 can be quickly discharged through the water outlet 705, which can quickly clean the leaves and other impurities on the top of the partition plate 3, reduce the possibility of clogging in the rainwater collection well, and ensure the speed of rainwater collection in the rainwater collection well. While the reciprocating screw 6 is rotated by the rotating shaft of motor 5, it also drives the two abutment blocks 601 on its side to rotate. At the same time, the filter plate 901 is limited by the rectangular groove 8, so that the abutment blocks 601 abut against the upper side of the filter plate 901 when they rotate, causing the filter plate 901 to move continuously downward and compress the compression spring 902. When the abutment blocks 601 rotate to release the contact with the filter plate 901, the filter plate 901 returns to its original position inside the rectangular groove 8 by the rebound force of the compression spring 902, so that the filter plate 901 generates continuous vibration. This causes the filter plate 901 to vibrate some of the small stones flowing to the upper side, so that the small stones and other impurities can be vibrated out from the holes inside the filter plate 901, thereby further increasing the speed of rainwater collection and filtration in the rainwater collection well. Once the top of the C-shaped plate 703 is full of leaves and other impurities, the two C-shaped plates 703 are moved backward, causing the leaves and other impurities on their upper sides to be moved out and removed. At the same time, as the C-shaped plates 703 move, they also cause the T-shaped scraper 704 to move forward. The vertical plate of the T-shaped scraper 704 scrapes off some small stones and other impurities from the top of the filter plate 901, thus quickly cleaning the top of the filter plate 901.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
