[0038] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] The rainwater collecting and filtering device for garden engineering provided by the embodiments of the present application solves the problem that rainwater takes away planting soil and the like in the garden and reduces the nutrients in the soil, and realizes separation of sundries and planting soil and the like in rainwater, thereby achieving primary filtering of rainwater.

[0040] The technical solutions in the embodiments of the present application are as follows to solve the above technical problems:

[0041] The wave part 201 is used to make the planting soil and the like flow through the through hole 202, and then the filter bag 302 is used for filtering, so that the planting soil and the like are retained in the filter bag 302, facilitating subsequent use. Meanwhile, rainwater is also primarily filtered, facilitating subsequent use of the collected rainwater.

[0042] For better understanding of the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings and specific embodiments of the specification.

[0043] Referring to Figures 1-7 A rainwater collecting filter for garden engineering, comprising a water inlet part 100 and a channel part 200, the water inlet part 100 is communicated with the channel part 200, and a wave part 201 is arranged in the channel part 200, a through hole 202 is arranged in the trough section 2024 of the wave part 201, a mounting part 300 is arranged in the channel part 200, a current collecting part 301 corresponding to the through hole 202 is arranged in the mounting part 300, a limiting frame 400 is arranged in the mounting part 300, a filter bag 302 is arranged on the limiting frame 400, and the position of the filter bag 302 corresponds to the current collecting part 301, an opening is arranged on the side of the mounting part 300 close to the water inlet part 100, a sealing plug 303 is arranged in the opening, the size of the opening is arranged to allow the limiting frame 400 and the filter bag 302 to pass through, and a drain port 304 is arranged on the other side of the mounting part 300, the drain port 304 is communicated with the channel part 200.

[0044] The limiting frame 400 comprises a plurality of limiting parts 401, the upper end of two adjacent limiting parts 401 is rotatably connected through a rotating shaft, and the lower end side wall of the limiting part 401 is in contact with each other, an annular sleeve 402 is clamped on the limiting part 401, and the side wall of the annular sleeve 402 is connected with the filter bag 302, so that the bag opening of the filter bag 302 is opened.

[0045] Referring to Figure 7 The filter bag 302 comprises an annular part 3021 and a conical part 3022, the annular part 3021 and the conical part 3022 are integrally connected, the annular part 3021 is connected with the annular sleeve 402, and the lower end of the conical part 3022 is projected as an acute angle.

[0046] By setting the lower end of the filter bag 302 as a prism or a pyramid, the sundries, silt and the like can be left at the bottom, and the rainwater can be discharged through other areas, so that the drainage speed of the filter bag 302 is increased.

[0047] Referring to Figure 2 and Figure 3The waveform portion 201 includes a base 2021 and several peak sections 2022. The base 2021 is connected to the channel portion 200. The base 2021 includes a plane portion 2023 and a trough section 2024. The end of the peak section 2022 is rotatably connected to the plane portion 2023 through a rotating shaft. The side wall of the channel portion 200 is also provided with a sealing portion 500. A connecting rod 501 is connected to the sealing portion 500. The connecting rod 501 extends to the outside of the sealing portion 500 and is connected to the rotating shaft. A self-driving component 600 is also provided in the sealing portion 500. The self-driving component 600 is connected to the connecting rod 501 for driving the connecting rod 501 to rotate.

[0048] By providing the sealing portion 500 and providing a movable seal at the connection between the connecting rod 501 and the sealing portion 500, the rotation of the connecting rod 501 is not hindered, while also ensuring the sealing effect and preventing rainwater from entering the sealing portion 500.

[0049] The self-driving component 600 can make the crest section 2022 and the trough section 2024 fit together, thereby transforming the entire waveform portion 201 into a flat portion 2023 , which will not hinder the flow of rainwater and is convenient for use in heavy rainy weather.

[0050] The height of the peak section 2022 is less than or equal to the height of the trough section 2024 , and the curve projection of the peak section 2022 and the curve projection of the trough section 2024 are located on the same parabola.

[0051] This is to ensure that the crest section 2022 and the trough section 2024 can be more perfectly matched. In addition, the crest section 2022 and the trough section 2024 can be set to the same height, so that the height of the plane portion 2023 is the lowest, which facilitates rainwater to flow out of the channel portion 200 quickly.

[0052] Reference Figure 4 、 Figure 5 and Figure 6 The self-drive component 600 includes an elastic part 601, which is connected to a rack 602. The rack 602 is slidably connected to the sealing part 500. A gear 603 matching the rack 602 is rotatably connected in the sealing part 500. The gear 603 is sleeved on the connecting rod 501 and is configured to drive the connecting rod 501 to rotate. The other end of the rack 602 is connected to a pull rope 604. A sealing sleeve 605 is provided in the sealing part 500. The pull rope 604 passes through the sealing sleeve 605 and extends to the water inlet part 100. A wheel group 700 is provided in the water inlet part 100. The pull rope 604 is wound around the wheel group 700, and the other end of the pull rope 604 is connected to the buoyancy part 606.

[0053] The wheel assembly 700 includes a supporting wheel 701 and a reversing wheel 702 . The supporting wheel 701 is installed on the outside of the sealing portion 500 , and the reversing wheel 702 is located at the bottom of the water inlet portion 100 .

[0054] The elastic part 601 can be configured as a torsion spring or a linear spring, so as to ensure that the elastic part 601 is deformed when the rack 602 moves. Even a spring sheet or an elastic rope can be used.

[0055] The buoyancy part 606 can be made of a float, plastic, foam, etc.

[0056] The support wheel 701 can protect the pull rope 604 and reduce the wear and tear. The reversing wheel 702 can make the buoyancy part 606 rise and pull the rack 602 to move outside the sealing part 500, thereby driving the gear 603 to rotate clockwise and the peak section 2022 to rotate clockwise, thereby being retracted into the trough section 2024.

[0057] In addition, after the crest section 2022 is partially pulled up and rotated, the crest section 2022 and the trough section 2024 can be quickly fitted together under the impact of the water flow.

[0058] The sealing sleeve 605 allows the drawstring 604 to extend smoothly to the outside world, while preventing water in the water inlet 100 from entering the sealing portion 500. The sealing sleeve 605 can be a hollow cylinder filled with a sealing material such as rubber or capillary thread. The drawstring 604 is made of a hard material that is not easily torn, such as fishing line.

[0059] Reference Figure 7 The collecting portion 301 includes a rectangular portion 3011 and a trapezoidal portion 3012. The rectangular portion 3011 and the trapezoidal portion 3012 are integrated. The rectangular portion 3011 is connected to the mounting portion 300. The trapezoidal portion 3012 is configured to be narrow at the bottom and wide at the top. The opening of the trapezoidal portion 3012 is configured to be covered by the inlet of the filter bag 302, and the rectangular portion 3011 is configured to cover all the through holes 202 located in the same trough section 2024.

[0060] The rectangular portion 3011 can cover all the through holes 202 , so that more through holes 202 can be provided, and the trapezoidal portion 3012 can collect rainwater to prevent it from falling outside the filter bag 302 .

[0061] Reference Figure 4 The lower side wall of the peak section 2022 is connected to the first magnet 800, and the plane portion 2023 is connected to the second magnet 801 corresponding to the position of the first magnet 800, and the first magnet 800 is set to be in the same plane as the lower side wall of the peak section 2022, and the second magnet 801 is set to be in the same plane as the plane portion 2023, and the first magnet 800 and the second magnet 801 are set to attract each other.

[0062] Through the attraction of the first magnet 800 and the second magnet 801, when the buoyancy part 606 is subjected to a certain buoyancy, the wave crest section 2022 cannot be separated from the flat section 2023, so when the buoyancy is greater than the attraction of the first magnet 800 and the second magnet 801, the wave crest section 2022 and the flat section 2023 are suddenly separated, the magnetic attraction is lost, the buoyancy part 606 quickly rises, thereby driving the wave crest section 2022 to quickly adhere to the wave trough section 2024, so that the wave crest section 2022 cannot be in an inclined state for a long time, thereby enabling the water flow to more easily pass through the channel part 200.

[0063] The water inlet part 100 is provided with a filter screen 900, and the bottom of the water inlet part 100 is lower than the bottom of the channel part 200.

[0064] The side of the buoyancy part 606 away from the channel part 200 is provided as an inclined surface, and the inclined direction is downward from the channel part 200 to the water inlet part 100.

[0065] By providing the side of the buoyancy part 606 as an inclined surface, the debris in the rainwater entering the water inlet part 100 is more easily affected by the inclined surface and falls to the side away from the channel part 200, thereby reducing the possibility of entering the channel part 200, and the buoyancy part 606 and the wave-shaped part 201 can also play a blocking role to block the debris from entering the channel part 200.

[0066] The buoyancy part 606 can adopt a sphere or a triangular prism, and when the buoyancy part 606 adopts a triangular prism, the side projection of the triangular prism can be a right triangle, an isosceles triangle, or any triangle, but the length of the line segment of the inclined surface part should not be less than the length of the line segment of the other two side surfaces.

[0067] When rainwater in the garden needs to be treated, the rainwater can enter the water inlet part 100 through the filter screen 900, and the rainwater first falls to the bottom of the water inlet part 100. Similarly, the filter screen 900 filters branches, stones, and the like, and the branches and stones passing through the filter screen 900 also fall to the bottom of the water inlet part 100. Thus, the amount of debris entering the channel part 200 is reduced.

[0068] After the rainwater enters the channel part 200, the rainwater flows through the wave-shaped section, and when the rainwater is less, the rainwater flows along the wave-shaped section and gradually passes through the through hole 202 and the flow collecting part 301 and enters the filter bag 302. After being filtered by the filter bag 302, the silt, dust, and the like in the rainwater can be filtered out, so that the debris in the rainwater can be completely filtered out, thereby ensuring the cleanliness of the rainwater and facilitating subsequent use. In addition, the collected silt, planting soil, and the like can be directly placed in the garden after being dried or without being dried, thereby ensuring that sufficient nutrients are provided for plants in the garden.

[0069] The rainwater passing through the filter bag 302 will pass through the drain port 304 and mix with the water in the channel portion 200. In addition, the corrugated portion 201 can also block debris such as stones and branches, further reducing the debris in the channel portion 200 and preventing the channel portion 200 from being blocked after long-term use.

[0070] When the filter bag 302 needs to be removed, it is only necessary to remove the sealing plug 303 and then take out a limiting part 401. The multiple limiting parts 401 can be rotated. After taking out a limiting part 401, the limiting part 401 can be rotated, and then the taken-out limiting part 401 moves upward, and the limiting part 401 in the installation part 300 continues to enter the water inlet part 100 and is taken out. In this way, multiple limiting parts 401 can be quickly taken out.

[0071] During installation, the same method is used to make the limiting portion 401 close to the drain outlet 304 press against the side wall of the drain outlet 304, and a movable limiting block is provided on the limiting portion 401 close to the water inlet portion 100, and a limiting groove is opened on the installation portion 300, so that after the limiting block is inserted into the limiting groove, the positions of multiple limiting portions 401 can be fixed.

[0072] The filter bag 302 can be easily installed on the limiting portion 401. The limiting portion 401 can be provided with a slot, and the annular sleeve 402 can be provided with a latch rod, which can be inserted into the slot. The filter bag 302 can be connected to the annular sleeve 402 by heat melting or sewing to ensure that the filter bag 302 will not be separated from the annular sleeve 402 when rainwater hits. After installation, the sealing plug 303 can be installed to prevent rainwater from entering the installation portion 300 through the water inlet 100.

[0073] When there is heavy rain, the amount of water in the water inlet 100 increases, causing the buoyancy portion 606 to float. The buoyancy portion 606 then drives the pull rope 604, pulling the rack 602 to move. The rack 602 drives the gear 603 to rotate, which in turn drives the connecting rod 501 to rotate. The connecting rod 501 then drives the crest section 2022 to rotate, causing the crest section 2022 to rotate 180 degrees and fall into the trough section 2024. This exposes the flat section 2023, reducing the resistance to rainwater flow and allowing it to drain quickly. This prevents clogging of the channel 200 due to heavy rain and other weather conditions. Furthermore, the entire process does not consume additional energy, thus saving energy and being environmentally friendly. Simultaneously, the elastic portion 601 is pulled, generating elastic force.

[0074] When the rainwater decreases and the water in the water inlet part 100 becomes less, the buoyancy part 606 drops, the pull rope 604 is loosened, and the rack 602, the gear 603 and the connecting part return to the original position under the rebound force of the elastic part 601, so that the wave crest section 2022 and the wave trough section 2024 are combined into the wave-shaped part 201 again. Thus, the separation of sundries in the rainwater is continued.

[0075] In summary, compared with the prior art, the present application has the following beneficial effects:

[0076] 1. The wave-shaped section can block the speed of the rainwater, so that the rainwater and the silt flow through the filter bag 302 first, so as to retain the planting soil and silt, and then flow out, and when the rainwater is large, the rainwater can directly pass through the wave-shaped part 201 and flow out along the channel part 200 for subsequent collection, so as to avoid blockage.

[0077] 2. The position of the filter bag 302 can be quickly fixed by the limiting frame 400, and the filter bag 302 is also convenient to take out, so that the soil in the filter bag 302 can be taken out for subsequent use and recycling.

[0078] It should be noted that, in the present text, relational terms such as first and second and the like can only be used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations.
