Technical Field

[0001] This invention relates to the field of rainwater treatment technology, and more specifically, to an integrated rainwater filtration, collection and utilization device and its usage method. Background Technology

[0002] Existing rainwater harvesting and utilization systems often suffer from problems such as inadequate filtration, low collection efficiency, and low automation. Traditional rainwater harvesting devices mostly employ simple filtration structures, which are insufficient to effectively remove impurities from rainwater, resulting in low-quality collected rainwater unsuitable for direct use in irrigation, toilet flushing, and other domestic purposes. Furthermore, collection tanks often require immediate manual replacement, increasing labor intensity and reducing harvesting efficiency. In addition, most existing rainwater harvesting devices lack automatic control and regulation functions, failing to automatically adjust collection strategies based on rainwater collection conditions for continuous collection, thus hindering the effective utilization of rainwater resources. Summary of the Invention

[0003] 1. The technical problem that the invention aims to solve

[0004] To address the shortcomings and deficiencies of existing technologies, this invention aims to solve the problems of existing rainwater harvesting devices, which mostly employ simple filtration structures, making it difficult to effectively remove impurities from rainwater. This results in low-quality collected rainwater that cannot be directly used for irrigation, toilet flushing, or other domestic purposes. Furthermore, the collection boxes often require immediate manual replacement, increasing labor intensity and reducing rainwater harvesting efficiency. In addition, most existing rainwater harvesting devices lack automatic control and adjustment functions, failing to automatically adjust collection strategies based on rainwater collection conditions for continuous collection, thus hindering the effective utilization of rainwater resources. Therefore, this invention proposes an integrated rainwater filtration, collection, and utilization device and its usage method.

[0006] To achieve the above objectives, the technical solution provided by this invention is as follows:

[0007] The present invention provides an integrated rainwater filtration, collection and utilization device, including a housing, a second circular groove on the top of the housing, a first circular groove inside the housing, the first circular groove being directly below the second circular groove, and a filter component for filtering rainwater being disposed inside the second circular groove.

[0008] A fixed circular plate is fixedly connected to the top inner wall of the first circular groove. A circular hole is opened inside the fixed circular plate. A rotating circular plate is rotatably connected to the bottom inner wall of the first circular groove. Multiple collection boxes are placed on the top of the rotating circular plate through a placement component.

[0009] The bottom of the outer casing is provided with a control component for controlling the rotation of the rotating disc.

[0010] Furthermore, the filter assembly includes a second annular groove fixedly connected to the inner wall of the top of the second circular groove. A first annular block is engaged inside the second annular groove. An arc-shaped strainer is fixedly connected inside the first annular block. Multiple second fixing screws are threaded through the inner wall of the first annular block. The second fixing screws are used to fix the outer shell and the first annular block. An annular filter screen is fixedly connected to the bottom of the arc-shaped strainer. An arc-shaped plate is fixedly connected to the bottom of the annular filter screen. The annular filter screen, the arc-shaped strainer, and the arc-shaped plate are connected at their middle positions.

[0011] Furthermore, a fixing ring is fixedly connected to the bottom inner wall of the second circular groove, and a top block slides through the inside of the fixing ring. The top of the top block is conical, and the top of the top block passes through the arc plate and extends into the interior of the arc plate. A first spring is fixedly connected between the bottom of the top block and the bottom inner wall of the second circular groove.

[0012] Furthermore, the placement assembly includes multiple placement slots opened on the top of the rotating circular plate, a support plate slidingly passing through the interior of the placement slots, two symmetrically arranged second springs fixedly connected between the bottom of the support plate and the bottom inner wall of the placement slots, a collection box placed on the top of the support plate, and a rotating shaft fixedly passing through the interior of the rotating circular plate.

[0013] Furthermore, the bottom of the fixed circular plate is provided with multiple pawls, and a ratchet is fixedly sleeved on the outer wall of the rotating shaft. The ratchet and pawls are used in conjunction.

[0014] Furthermore, the inner wall of the second circular groove is provided with a connected annular hole, the inside of the outer shell is provided with an annular cavity, the annular cavity is connected with the annular hole, the bottom inner wall of the annular cavity is inclined, one side of the bottom inner wall of the annular cavity is provided with a connected inclined groove, the top of the first circular groove is provided with a connecting hole, and the top of the connecting hole is connected with the bottom of the inclined groove.

[0015] Furthermore, the control component includes two fixed rods fixedly connected to the bottom of the housing and symmetrically arranged. The bottom of the two fixed rods is fixedly connected to the same base plate. A mounting circular plate is rotatably passed through the middle of the bottom of the housing. A torsion spring is fixedly connected between the top of the mounting circular plate and the top of the rotating shaft. A hexagonal plate is fixedly connected to the bottom of the mounting circular plate. The hexagonal plate is located below the housing. Multiple threaded grooves are opened at the bottom of the hexagonal plate. Multiple first fixing screws pass through the internal threads of the base plate. The first fixing screws are threadedly connected to the threaded grooves.

[0016] Furthermore, a rectangular hole is provided on one side of the first circular groove, a door panel is hinged inside the rectangular hole, a buckle is fixedly connected to one side of the door panel, a hook is fixedly connected to one side of the outer shell, the hook and buckle are used together, and multiple legs are fixedly connected to the bottom of the outer shell.

[0017] A method for using an integrated rainwater filtration, collection, and utilization device specifically includes the following steps:

[0018] S1. Rainwater slides down from the top of the arc-shaped leak plate and is filtered by both the arc-shaped leak plate and the annular filter. Impurities are left in the annular filter. The filtered rainwater enters the annular cavity through the annular hole and then flows into the connecting hole through the inclined groove. The collection box is placed on the rotating circular plate and supported by the support plate and the second spring. Rainwater enters the collection box.

[0019] S2. When impurities increase in the annular filter screen, the top block moves downward under pressure, and the impurities fall below the arc plate. When cleaning the impurities, unscrew the second fixing screw and take out the arc plate, annular filter screen and arc plate as a whole for cleaning.

[0020] S3. After the collection box is filled with water, it drives the support plate to move down, squeezing the second spring. When the collection box moves to the bottom of the fixed circular plate, the rotating circular plate rotates under the action of the torsion spring, turning the next empty collection box to the bottom of the connection hole. The second spring returns to its original position, and the support plate drives the empty collection box to move up to the circular hole of the fixed circular plate to collect water.

[0021] S4. Open the door panel using the buckle and hook, remove the full water collection box and put in the empty collection box, unscrew the first fixing screw, release the hexagonal plate brake, rotate the hexagonal plate in the opposite direction to maintain the torsion spring torque, and use the ratchet and pawl to prevent the rotating shaft from reversing, ensuring that the collection boxes are replaced in sequence.

[0022] 3. Beneficial effects

[0023] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0024] This invention achieves multi-stage filtration of rainwater through a set of filtration components such as an arc-shaped perforated plate, a ring-shaped filter screen, and an arc-shaped plate, effectively removing impurities from the rainwater and improving the quality of the collected rainwater. Simultaneously, the collection box is automatically placed on a rotating circular plate by a placement component, and is automatically replaced as rainwater is collected, requiring no manual intervention and greatly improving collection efficiency.

[0025] This device uses a control component to automatically rotate the disc. When the collection tank is full of water, it automatically rotates the next empty collection tank to the bottom of the connection hole, thus achieving automatic tank replacement. Simultaneously, the ratchet and pawl design prevents the rotating shaft from reversing, ensuring the accuracy and stability of the collection tank replacement.

[0026] The filter components, including the arc-shaped filter plate, ring-shaped filter screen, and arc-shaped plate, are fixedly connected to the outer casing by a second fixing screw. When it is necessary to clean impurities, simply unscrew the second fixing screw to remove the entire filter component, facilitating cleaning and maintenance. In addition, the door panel is connected to the outer casing by latches and hooks, making it easy to open the outer casing for internal inspection and maintenance.

[0027] The device's interior is cleverly designed with multiple functional areas, including a filtration area, a collection area, and a control area. These areas work together to achieve functions such as rainwater filtration, collection, and automatic collection box replacement. Meanwhile, support legs at the bottom of the casing ensure the device's stability and safety. Attached Figure Description

[0049] Example 2

[0050] from Figure 1-9 As can be seen, in this embodiment of the integrated rainwater filtration and collection device, a rectangular hole 19 is provided on one side of the first circular groove 17. A door panel 5 is hinged inside the rectangular hole 19. A buckle 4 is fixedly connected to one side of the door panel 5. A hook 3 is fixedly connected to one side of the outer shell 1. The hook 3 and the buckle 4 are used together. Multiple support legs 2 are fixedly connected to the bottom of the outer shell 1.

[0051] This equipment can be installed in a drainage ditch, with multiple sets of equipment arranged at intervals on the ground 40 of the drainage ditch. When it rains, rainwater enters the arc-shaped drain plate 6 through the perforated holes of the drainage ditch perforated cover plate 39. The drainage ditch perforated cover plate 39 is removable for easy maintenance in the future.

[0052] Example 3

[0053] from Figure 1-9 As can be seen, the method of using the integrated rainwater filtration, collection, and utilization device of this embodiment specifically includes the following steps:

[0054] S1. Rainwater slides down from the top of the arc-shaped leak plate 6 and is filtered by the arc-shaped leak plate 6 and the annular filter 16. Impurities are left in the annular filter 16. The filtered rainwater enters the annular cavity 22 through the annular hole 20 and then flows into the connecting hole 24 through the inclined groove 23. The collection box 12 is placed on the rotating circular plate 11 and supported by the support plate 32 and the second spring 33. Rainwater enters the collection box 12.

[0055] S2. When impurities increase in the annular filter screen 16, the top block 25 moves downward under pressure, and the impurities fall below the arc plate 15. When cleaning the impurities, unscrew the second fixing screw 27 and take out the arc plate 6, the annular filter screen 16 and the arc plate 15 as a whole for cleaning.

[0056] S3. After the collection box 12 is filled with water, it drives the support plate 32 to move down and squeezes the second spring 33. When the collection box 12 moves to the bottom of the fixed circular plate 13, the rotating circular plate 11 rotates under the action of the torsion spring 38, and the next empty collection box 12 is rotated to the bottom of the connecting hole 24. The second spring 33 is reset, and the support plate 32 drives the empty collection box 12 to move up to the circular hole of the fixed circular plate 13 to collect water.

[0057] S4. Open the door panel 5 through the buckle 4 and hook 3, take out the full water collection box 12 and put in the empty collection box 12, unscrew the first fixing screw 7, release the braking state of the hexagonal plate 36, rotate the hexagonal plate 36 in the opposite direction to maintain the torque of the torsion spring 38, and prevent the rotating shaft 30 from reversing, ensuring that the collection boxes 12 are replaced in sequence.

[0058] In this application, during use, rainwater slides down through the top of the arc-shaped drain plate 6. At this time, the rainwater is filtered through the arc-shaped drain plate 6 and enters the interior of the second circular groove 18. Impurities enter the interior of the annular filter screen 16 and can be filtered again through the annular filter screen 16. The filtered rainwater passes through the surface of the arc-shaped plate 15 and enters the interior of the annular cavity 22 through the annular hole 20. The inner wall of the annular cavity 22 is higher on one side and lower on the other side, so that the rainwater enters the interior of the connecting hole 24 through the inclined groove 23 and is then collected by the collection box 12.

[0059] As the impurities inside the annular filter 16 gradually increase, the pressure on the top of the top block 25 gradually increases. When it reaches a certain weight, the top block 25 compresses the first spring 26 and causes the lower half of the top block 25 to move down into the interior of the fixing ring 14. At this time, the impurities accumulate inside the annular filter 16 and are collected. When it is necessary to clean the impurities, the arc-shaped strainer 6 can be unscrewed through the second fixing screw 27. At this time, the arc-shaped strainer 6, the first annular block 9, the annular filter 16 and the arc-shaped plate 15 can be taken out from the inside of the outer shell as a whole, which is convenient for cleaning the internal impurities.

[0060] The top of a collection box 12 located below the connection hole 24 is inserted into the circular hole inside the fixed circular plate 13 to collect water. As the weight of the rainwater gradually increases, the collection box 12 drives the support plate 32 to move down and squeeze the second spring 33. When the collection box 12 moves to the bottom of the fixed circular plate 13, the rotating shaft 30 drives the rotating circular plate 11 to rotate under the torque of the torsion spring 38. At this time, the next collection box 12 is rotated to the bottom of the connection hole 24. At this time, the second spring 33 drives the support plate 32 to move up and drives the collection box 12 to move up into the circular hole of the fixed circular plate 13 to collect water.

[0061] As the number of collection boxes 12 increases, they need to be removed. At this time, the door panel 5 can be opened using the latch 4 and hook 3. After opening, the corresponding collection box 12 can be taken out and an empty collection box 12 can be placed in. At the same time, multiple first fixing screws 7 can be unscrewed, which releases the braking state of the hexagonal plate 36, allowing the hexagonal plate 36 to rotate in the opposite direction. This ensures the torque of the torsion spring 38. Meanwhile, the ratchet 29 and pawl 28 prevent the rotating shaft from reversing, making it convenient to use.

[0062] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
