Description

Technical Field

[0001] This utility model relates to the technical field of rainwater filtration devices, and in particular to a rainwater collection, filtration and impurity separation device. Background Technology

[0002] In the construction industry, especially in residential buildings, factories, and agricultural greenhouses, collecting rainwater from rooftops via eaves and downpipes is a common and efficient method of rainwater utilization. However, the quality of rainwater from rooftop runoff has its own unique characteristics: the initial rainwater is mixed with a large amount of impurities accumulated on the roof, such as leaves, branches, moss, sand, dust, bird droppings, and degradation products from the roofing materials themselves.

[0003] A removable filter can be installed at the corner of a downpipe or in a vertical pipe. However, during the initial heavy rainfall on a roof, the strong scouring force and high concentration of impurities cause traditional filters to become clogged instantly, rendering them ineffective in handling this most critical and contaminated water flow. Furthermore, rainwater dripping vertically from the eaves or accelerating through the downpipe has a significant impact force, easily breaking up impurities already trapped on the filter screen, allowing fine particles to penetrate and reducing the filtration effect. Therefore, a rainwater collection, filtration, and impurity separation device is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rainwater collection, filtration, and impurity separation device, comprising: The trough includes a water trough installed at the eaves. Two storage buckets are provided at the bottom of the water trough. An embedded stepped groove is provided between the water trough and the storage buckets. A fence plate for intercepting branches and debris is placed inside the stepped groove. The fence plate is detachably installed in the stepped groove to intercept large particles such as leaves and branches and prevent them from entering the subsequent pipes and causing blockage. The pipe assembly includes a guide water pipe that is fixed to the storage hopper. The bottom end of the guide water pipe is provided with a connecting piece. The guide water pipe has a Y-shaped structure design, which is used to guide rainwater from the confluence of two storage hoppers to the filtration section. Its vertical pipe end is an elastic telescopic pipe structure, which can adjust the length and angle according to the installation environment to reduce the impact of rainwater. The filter section includes a cover plate that docks with the connecting piece and is fastened to the top of the filter cylinder. The inner wall of the filter cylinder is connected to a stepped ring plate, and a perforated plate for isolating sand and gravel is placed on the surface of the stepped ring plate. The interior of the filter cylinder is divided by the stepped ring plate and the perforated plate into a sand and gravel layer cavity for rainwater filtration and a water flow transfer cavity. The bottom of the front of the filter cylinder is connected to a water outlet pipe that communicates with the water flow transfer cavity. A sand and gravel layer is laid on the perforated plate to adsorb and intercept fine particulate impurities. The stepped ring plate is used to support the perforated plate and divide the cavity, so that rainwater enters the water flow transfer cavity after being filtered through the sand and gravel layer.

[0006] Preferably, a guide plate is bolted to the top of the water tank. The guide plate is inclined and placed under the eaves. The guide plate is used to accurately guide the rainwater flowing down from the eaves into the water tank. Its inclination angle is adjustable to adapt to different eaves structures.

[0007] Preferably, the back of the guide plate is provided with several seam plates inserted into the gaps in the eaves. The seam plates are used to securely fasten the guide plate into the gaps in the eaves tiles, thereby enhancing overall stability and preventing displacement caused by strong winds or rain.

[0008] Preferably, the guide water pipe has a Y-shaped structure design, and the vertical end of the guide water pipe is an elastic telescopic pipe structure. The elastic telescopic pipe structure allows the guide water pipe to be flexibly adjusted in length during installation, avoiding stress concentration or poor connection due to position deviation.

[0009] Preferably, the connecting component includes a plug pipe that connects to the elastic telescopic tube of the guide water pipe, and the outer diameter of the bottom end of the plug pipe is reduced and inserted into the pipe at the top of the cover plate. A rubber ring is fitted on the surface of the plug pipe through an annular groove, and the rubber ring fits against the inner wall of the cover plate pipe. The plug pipe is used to insert into the cover plate pipe to achieve quick connection.

[0010] Preferably, the insertion tube is movably connected to a locking shaft on both the left and right sides, and a support plate is connected to the end of the locking shaft. A chuck and a spring are sequentially fitted on the surface of the locking shaft from top to bottom, and the two ends of the spring abut against the inner end face of the support plate and the chuck, respectively. A locking plate adapted to engage with the locking shaft is provided on the outer side of the end of the cover plate tube. The locking shaft can rotate and engage in the groove of the locking plate during insertion. The spring pushes the chuck tightly against the locking plate through its elastic force, forming a self-locking structure.

[0011] Preferably, two lifting rods are symmetrically connected to the left and right sides of the top of the perforated plate, and the lifting rod is composed of a rod end and a ring end. The bottom of the cover plate has inner grooves on the left and right sides for the lifting rods to pass through. The lifting rods are used to easily lift the perforated plate during maintenance, which is convenient for cleaning or replacing the sand and gravel layer.

[0012] This utility model has at least the following beneficial effects: 1. This utility model uses the grid plate in the groove to initially intercept large particles of impurities such as branches and leaves, and the sand and gravel layer and perforated plate in the filter section to perform secondary filtration, effectively removing fine particles, preventing the filter screen from clogging instantly, and extending the service life of the device.

[0013] 2. The device uses an elastic telescopic design for the guide water pipe in the pipe assembly to mitigate the impact of rainwater; the connecting parts are locked with springs and clamps to ensure a firm connection, prevent rainwater from washing away the parts and improve the reliability of the device.

[0014] 3. The trough of this device can be quickly fixed to the eaves by guide plates and slotted plates, and the filter section can be easily lifted by lifting rods to facilitate cleaning and replacement of filter media, thus reducing maintenance costs. Attached Figure Description

The inner wall of the filter cylinder 31 is connected to a stepped ring plate 36, and a perforated plate 34 for isolating sand and gravel is placed on the surface of the stepped ring plate 36. The interior of the filter cylinder 31 is divided by the stepped ring plate 36 and the perforated plate 34 into a sand and gravel layer cavity for rainwater filtration and a water flow transfer cavity. The bottom end of the front of the filter cylinder 31 is connected to a water outlet pipe 32 and communicates with the water flow transfer cavity.

[0021] The back of the guide plate 14 is provided with several seam plates 15 that are inserted into the gaps in the eaves.

[0022] The guide pipe 21 has a Y-shaped structure design, and the vertical end of the guide pipe 21 is an elastic telescopic pipe structure.

[0023] The connecting part 22 includes a plug pipe 221 that connects to the elastic telescopic tube of the guide water pipe 21. The outer diameter of the bottom end of the plug pipe 221 is reduced and inserted into the top pipe of the cover plate 33. A rubber ring 222 is fitted on the surface of the plug pipe 221 through an annular groove, and the rubber ring 222 is in contact with the inner wall of the pipe of the cover plate 33.

[0024] Both sides of the insertion tube 221 are movably connected to the retaining shaft 223, and the end of the retaining shaft 223 is connected to the support plate 224. The surface of the retaining shaft 223 is fitted with a chuck 226 and a spring 225 from top to bottom, and the two ends of the spring 225 abut against the inner end face of the support plate 224 and the chuck 226 respectively.

[0025] Two lifting rods 35 are symmetrically connected to the top left and right sides of the perforated plate 34. Each lifting rod 35 consists of a rod end and a ring end. The bottom left and right sides of the cover plate 33 have inner grooves for the lifting rods 35 to pass through.

[0026] The water trough 11 is used to collect rainwater flowing from the eaves, and its width and depth are designed to accommodate different rainfall amounts; the water storage hopper 12 is used to concentrate rainwater and guide it to the pipe assembly 2 to prevent rainwater from splashing; the fence 13 is detachably installed in the step groove to intercept large particles such as leaves and branches and prevent them from entering the subsequent pipes and causing blockages.

[0027] The guide pipe 21 has a Y-shaped structure and is used to guide rainwater from the two storage hoppers 12 to the filter section 3. Its vertical pipe end is a flexible telescopic pipe structure, which can adjust the length and angle according to the installation environment to reduce the impact of rainwater. The connecting piece 22 is used to connect the guide pipe 21 and the filter section 3 to ensure smooth water flow and good sealing. The cover plate 33 is used to seal the top of the filter cylinder 31 to prevent rainwater from overflowing and impurities from entering. The perforated plate 34 is covered with a layer of sand and gravel to adsorb and intercept fine particulate impurities. The stepped ring plate 36 is used to support the perforated plate 34 and divide the chamber, so that rainwater enters the water transfer chamber after being filtered by the sand and gravel layer.

[0028] The guide plate 14 is used to accurately guide the rainwater flowing down from the eaves into the water trough 11. Its tilt angle is adjustable to adapt to different eave structures. The seam plate 15 is used to firmly snap the guide plate 14 into the seam of the eaves tiles to enhance the overall stability and prevent displacement caused by strong winds or rain. The elastic telescopic tube structure allows the guide pipe 21 to be flexibly adjusted in length during installation to avoid stress concentration or poor connection due to position deviation.

[0029] The insertion pipe 221 is used to insert into the cover plate 33 pipe to achieve quick connection; the rubber ring 222 is used to enhance the sealing and prevent rainwater leakage; the retaining shaft 223 can rotate and lock into the groove of the retaining plate 37 during insertion, and the spring 225 pushes the retaining plate 226 to press against the retaining plate 37 through elastic force to form a self-locking structure, ensuring a firm connection and easy quick disassembly; the lifting rod 35 is used to easily lift the orifice plate 34 during maintenance, which is convenient for cleaning or replacing the sand and gravel layer, and its ring end is easy to operate by hand.

[0030] Working principle: According to Figure 1 , Figure 2 and Figure 3 As shown, during the assembly process, the water tank 11 is fixed to the wall surface under the eaves with bolts, so that the guide plate 14 is placed and attached to the lower end of the eaves, and the seam plate 15 is driven to snap into the tile seam of the eaves to fix the water tank 11. At this time, the fence plate 13 is embedded in the stepped groove inside the water tank 11. At this time, the elastic telescopic tube at the bottom of the guide water pipe 21 hangs down. By pulling the plug pipe 221, the plug pipe 221 can be pulled and guided to the top of the cover plate 33. Secondly, according to Figure 5 and Figure 6 As shown, the bottom end of the connector 221 is inserted into the pipe of the cover plate 33, so that the rubber ring 222 abuts against the inner wall of the pipe of the cover plate 33. At this time, the locking shaft 223 can rotate and be embedded into the groove of the locking plate 37. Under the elastic force of the spring 225, the locking disc 226 is pushed, causing the locking disc 226 to abut against the bottom surface of the locking plate 37 during the push, ensuring the connection stability between the connector 221 and the pipe of the cover plate 33, and ensuring that it will not easily break during daily use. When it rains, rainwater carries branches, moss, sand, and dust from the roof. Bird droppings and other debris are moved into the water tank 11. Larger debris such as branches are intercepted by the fence 13. After initial interception, the rainwater enters the water guide pipe 21 through the storage hopper 12 and then enters the sand and gravel layer cavity inside the filter cylinder 31 through the pipe at the top of the cover plate 33. The sand and gravel can intercept small debris in the water flow, allowing the water to enter the water transfer cavity at the bottom of the filter cylinder 31 after passing through the through hole of the perforated plate 34. The water is then guided to the designated water storage tank through the outlet pipe 32 in conjunction with the external water pipe for subsequent use.
