[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] Please see Figures 1-9 As shown, the purpose of this embodiment is to provide a garden rainwater collection device, including a collection box 1 for collecting rainwater. A fixing plate 2 is fixedly installed on the top of the collection box 1. The upper surface of the fixing plate 2 is an inverted conical surface inclined towards the center. Collection plates 3 are hinged around the collection box 1. Diversion grooves 31 are opened on the collection plates 3. The collection plates 3 are used to increase the amount of rainwater collected.

[0033] The fixed plate 2 has several guide channels 21 arranged in a ring array. These guide channels 21 start from the outer edge of the fixed plate 2 and are evenly distributed at certain intervals and angles until they approach the center area. The main function of the guide channels 21 is to guide rainwater to the center area, reduce the residence time of rainwater on the surface of the fixed plate 2, and thus reduce the loss of rainwater evaporation. Each guide channel 21 has several through holes 22. A column hole 23 is opened through the center of the fixed plate 2. This column hole 23 is located at the intersection of all the guide channels 21 and is another important channel for rainwater to flow to the collection box 1. The upper surface of the fixed plate 2 is designed as an inverted conical surface inclined towards the center. This design allows rainwater to flow naturally to the column hole 23. The diameter of the column hole 23 is larger than the diameter of the through holes 22. Part of the rainwater enters the collection box 1 through the through holes 22, and the other part of the rainwater enters the collection box 1 through the column hole 23, preventing rainwater from accumulating on the fixed plate 2.

[0034] A filter plate 4 is fixedly installed above the fixed plate 2. The filter plate 4 is used to prevent impurities such as fallen leaves in the garden from clogging the fixed plate 2 and thus hindering rainwater collection. The size of the filter plate 4 is slightly larger than that of the fixed plate 2 to ensure that it completely covers the fixed plate 2. A gap is left between the filter plate 4 and the fixed plate 2 to ensure that rainwater can pass through smoothly.

[0035] A grid-like diversion channel 31 is provided on one side of the collection plate 3, which increases the flow path of rainwater. The diameter of the diversion channel 31 gradually increases from one end to the other, which facilitates the flow of rainwater toward the fixed plate 2. One end of the collection plate 3 is located above the filter plate 4. This design ensures that when rainwater flows through the collection plate 3, it is first filtered by the filter plate 4 and then enters the fixed plate 2. This further ensures the quality of rainwater entering the collection box 1. A symmetrically arranged groove 32 is provided on the other side of the collection plate 3.

[0036] The collecting plate 3 and the filter plate 4 work together to achieve effective rainwater collection and filtration. The collecting plate 3 increases the rainwater collection area, while the filter plate 4 ensures the quality of the collected rainwater. The cooperation between the two makes the entire rainwater collection device more efficient and reliable.

[0037] Each side wall of the collection box 1 is provided with a square groove 11. One end of the collection plate 3 is hinged to one end of the square groove 11, allowing the collection plate 3 to rotate and adjust within the range of the square groove 11, thereby changing its tilt angle and collection area. Each side wall of the collection plate 3 is provided with a plurality of limiting grooves 12, which are connected to the square groove 11.

[0038] Each side wall of the collection box 1 is fixedly provided with two card holders 6. The card holders 6 are located at the bottom edge of the collection box 1. The card holders 6 have card slots 61, and support rods 5 are engaged in the card slots 61.

[0039] Limiting blocks 51 are fixedly installed at both ends of the support rod 5. When using the collecting plate 3, the limiting block 51 on one side is inserted into the limiting groove 12, and the limiting block 51 on the other side is inserted into the groove 32. By inserting the limiting block 51 on one side into the limiting groove 12 at different heights, the tilt angle of the collecting plate 3 can be adjusted. To ensure that the tilt angle of the collecting plate 3 remains stable after adjustment, the limiting blocks 51 at both ends are fixed in the limiting groove 12 and the groove 32 respectively with bolts. Figure 1 As shown, this ensures that the collection plate 3 remains stable and does not shake, even in severe weather conditions such as strong winds or heavy rain.

[0040] By adjusting the tilt angle of the collection plate 3, it can be better adapted to different rainfall conditions. During periods of heavy rainfall, the collection plate 3 can be adjusted to a more steep angle to guide rainwater towards the fixing plate 2 more quickly; during periods of light rainfall, the collection plate 3 can be adjusted to a gentler angle to increase the collection area and prolong the residence time of rainwater on the collection plate 3. Adjusting the tilt angle of the collection plate 3 can also improve rainwater collection efficiency. By optimizing the tilt angle, rainwater can flow more smoothly towards the fixing plate 2 as it passes through the collection plate 3, reducing resistance and loss during the collection process.

[0041] When the collecting plate 3 is not in use, it is engaged in the square groove 11. The collecting plate 3 can be gently pushed in along the direction of the square groove 11 until one side wall of the collecting plate 3 is tightly fitted against the inner wall of the square groove 11. After the collecting plate 3 is engaged in the square groove 11, its surface is flush with the side wall of the collecting box 1. Figure 2 As shown, this not only reduces the overall size of the device, but also prevents the collection plate 3 from shaking and colliding when not in use, thus extending its service life. When not in use, the support rod 5 can also be clipped into the slot 61 of the collection box 1, which not only ensures proper storage of the support rod 5, but also avoids safety hazards caused by the random placement of the support rod 5. Even in severe weather conditions such as strong winds or heavy rain, the support rod 5 will not be lost or damaged by wind and rain.

[0042] The storage design of the collection plate 3 and support rod 5 fully considers user convenience. Both installation and disassembly can be easily completed without complicated procedures or tools. When stored, the collection plate 3 and support rod 5 occupy almost no extra space, greatly improving the space utilization of the device, which is especially important in space-constrained garden environments.

[0043] An overflow outlet 13 is provided through one side wall of the collection tank 1. The overflow outlet 13 is elongated and located at the top of the collection tank 1, but below the edge of the fixing plate 2. This ensures that when the rainwater in the collection tank 1 reaches a certain amount, it can overflow smoothly from the overflow outlet 13 without overflowing from the fixing plate 2 above. The main function of the overflow outlet 13 is to prevent the collection tank 1 from being damaged due to excessive water accumulation during rainwater collection. When the rainwater in the collection tank 1 reaches its design capacity, the excess rainwater will overflow through the overflow outlet 13, thereby protecting the structural safety of the collection tank 1. Furthermore, a water outlet is provided at the bottom of one side wall of the collection tank 1 for easy drainage of the collected rainwater.

[0044] In practical use, when rainwater needs to be collected, the collecting plate 3 is rotated to expose its groove 32. The limiting block 51 at one end of the support rod 5 is inserted into the groove 32 and fixed with bolts. The limiting block 51 on the other side is inserted into the limiting groove 12 at a suitable height and fixed with bolts, thus fixing the tilt angle of the collecting plate 3. Rainwater first falls onto the filter plate 4 in the garden. After preliminary filtration by the filter plate 4, the rainwater continues to flow to the fixed plate 2 below. The rainwater flows in the guide channel 21 of the fixed plate 2 and enters the collecting box 1 below through the through hole 22 and the central column hole 23 on the guide channel 21. Simultaneously, the collecting box 1... The Zhou collection plate 3 also participates in rainwater collection. The diversion groove 31 on the collection plate 3 increases the flow path of rainwater, allowing rainwater to flow more smoothly to the fixed plate 2. When the rainwater in the collection box 1 reaches the specified capacity, the excess rainwater will overflow through the overflow port 13 on the upper side wall of the collection box 1. When it is necessary to discharge the collected rainwater, the outlet at the bottom of the side wall of the collection box 1 can be opened to discharge the rainwater to the specified location or for irrigation and other purposes. When it is necessary to store the collection plate 3, loosen the bolts on the limit blocks 51 at both ends, remove the support rod 5 and snap it into the slot 61, and rotate the collection plate 3 along the hinge point until the collection plate 3 is snapped into the square groove 11.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
