[0022] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] This embodiment proposes a high-flow-rate rainwater inlet structure, including a foundation 1, a rainwater grate 6, and a water-collecting stone 8;

[0024] like Figures 1-3 As shown, a rainwater channel 2 is provided on the foundation 1, which facilitates the collection and circulation of rainwater;

[0025] A rainwater inlet 3 is provided on the top of the rainwater channel 2, which facilitates the entry of ground rainwater into the rainwater channel 2;

[0026] The side wall of the rainwater channel 2 is covered with pads 4, and support brackets 5 are respectively installed on the pads 4;

[0027] The two ends of the rain grate 6 are fixedly installed on the support bracket 5, and a number of drainage holes 7 are evenly distributed on the rain grate 6; rainwater can pass through the rain grate through the drainage holes 7, and the rain grate 6 can filter the rainwater on the ground to prevent fallen leaves and other items from entering the rainwater channel 2 and causing blockage.

[0028] The water-collecting stones 8 are symmetrically laid on the outer sides of both ends of the rain grate 6. Several water-passing holes 9 are evenly distributed on the water-collecting stones 8. Ground rainwater can enter the lower layer of the water-collecting stones 8 through the water-passing holes 9. A filter layer 10 is set between the water-collecting stones 8 and the foundation 1. After the rainwater passes through the water-collecting stones 8, it can be filtered through the filter layer 10 and enter the rainwater inlet 3 through the gap between the pad blocks 4.

[0029] Furthermore, a slag collection basket 11 is provided at the upper end of the rainwater channel 2. The slag collection basket 11 can filter rainwater and prevent large particles of debris from entering the interior of the rainwater channel 2.

[0030] Furthermore, a molded mesh 12 is provided on the outer side of the filter layer 10, which makes the filter layer 10 a whole, facilitating construction and installation.

[0031] Furthermore, the upper end of the support bracket 5 is provided with a positioning groove 13, and both ends of the rain grate 6 are respectively provided with positioning bosses 14 that can cooperate with the fixed steps. The cooperation between the positioning bosses 14 and the positioning groove 13 makes the rain grate 6 easy to install and prevents it from shifting.

[0032] Furthermore, the pad 4 is provided with a drainage hole 15, which allows rainwater to pass through the filter layer 10 and enter the rainwater inlet 3 more quickly when there is a large amount of rainwater on the ground.

[0033] Furthermore, the diameter of the drain hole 7 is 1-2 cm. The smaller diameter of the drain hole 7 ensures that larger impurities such as fallen leaves cannot enter the interior, thus avoiding clogging of the water collection filter layer.

[0034] Furthermore, the number of water-collecting stones 8 is 4-6, which enables large-scale water collection and improves the overall water collection capacity of the rainwater inlet 3.

[0035] Furthermore, the upper end of the rainwater channel 2 is provided with a fixing strip 16 for fixing the slag collection basket 11. The slag collection basket 11 is mounted on the fixing strip 16 for easy removal and cleaning.

[0036] Working principle: This utility model increases the overall water collection area of ​​the rainwater inlet by setting water collection stones 8 on both sides of the rainwater grate 6; a filter layer 10 is laid under the water collection stones 8 to improve the support strength without affecting the collection of rainwater on the ground; the slag collection basket 11 can filter the rainwater and prevent large particles of debris from entering the rainwater channel 2.

[0037] It is understood that the above embodiments are merely exemplary models used to illustrate the principles of this utility model, and this utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
