[0017] EMBODIMENT

[0018] As Figures 1-2As shown, a fixed upward opening water collecting and guiding type umbrella includes an umbrella cover 1, a cable-stayed umbrella rod 3, a hollow drainage umbrella rod 4, an underground drainage pipe connecting port 7 and a fixed base 9. The umbrella cover 1 adopts a concave upward structure for collecting rainfall, and is in a shallow dish shape or a parabolic shape. An inclined flow guide surface is arranged on the inner side of the umbrella cover 1. The umbrella cover 1 is connected with the cable-stayed umbrella rod 3 through a plurality of umbrella ribs 2. The other end of the cable-stayed umbrella rod 3 is connected with the hollow drainage umbrella rod 4. The cable-stayed umbrella rod 3 provides structural support and stability. The hollow drainage umbrella rod 4 is used for guiding the collected rainwater to flow into the umbrella rod from the umbrella cover 1. Considering that the rainwater can easily flow into the umbrella along the inner side of the umbrella cover 1 after the umbrella cover 1 is concave upward, a drip-proof device 5 is arranged at a position 20-30 cm below the top end of the hollow drainage umbrella rod 4. The drip-proof device 5 includes a water collecting baffle 501 and circumferentially distributed drainage holes 502 to prevent the rainwater from flowing down along the umbrella rod from the inside of the umbrella cover. Raindrops on the inner side of the umbrella cover 1 are collected along the inclined flow guide surface and flow into the hollow drainage umbrella rod 4 in the middle. The water collecting baffle 501 is designed at a position 20-30 cm below the top end of the hollow drainage umbrella rod 4, and the circumferentially distributed drainage holes 502 are arranged, so as to collect the rainwater and flow the umbrella into the hollow drainage umbrella rod 4 through the drainage holes 502. A filter screen 6 is arranged at the opening of the top end of the hollow drainage umbrella rod 4 to prevent blockage. The filter screen 6 is in an annular mesh structure and is arranged at the connection position of the cable-stayed umbrella rod 3 and the hollow drainage umbrella rod 4. The bottom of the hollow drainage umbrella rod 4 is provided with the underground drainage pipe connecting port 7. The underground drainage pipe connecting port 7 is in communication with an underground drainage pipe 8 to form a complete drainage channel. The bottom end of the hollow drainage umbrella rod 4 is provided with the fixed base 9 buried in the ground to ensure that the whole structure is stable and reliable.

[0019] Calculation of the minimum diameter of the hollow drainage umbrella rod 4:

[0020] To ensure that the hollow drainage umbrella rod 4 has sufficient drainage capacity, the minimum inner diameter thereof should be calculated according to the water collecting area of the umbrella cover 1 and the local maximum rainfall intensity. The umbrella cover 1 adopts an upward opening concave structure, and the rainwater is collected in the center and drained through the underground drainage system of the hollow drainage umbrella rod 4.

[0021] Suppose that the effective water collecting projection area of the umbrella cover 1 is A (unit: m 2 ), and the local maximum design rainfall intensity is q (unit: L / s·m 2 ). Then the maximum flow rate of the rainwater flowing into the umbrella rod per unit time is:

[0022] Q=q×A;

[0023] The rainwater is drained in the umbrella rod in a gravity flow manner, and the average flow velocity is v (unit: m / s). Therefore, the inner diameter d of the umbrella rod should satisfy:

[0024] Q=v×(π×d 2 / 4);

[0025] Therefore, the minimum inner diameter of the umbrella rod is:

[0026]

[0027] After calculating the minimum inner diameter, it is also necessary to consider the impact of factors such as the ability of debris to pass through and the blockage of the orifice, and set a certain safety margin according to the actual situation.

[0028] For example, when the horizontal diameter of umbrella surface 1 is 2.5 meters (corresponding to an area of ​​approximately 4.91m²), 2 The design rainfall intensity is taken as 0.03 L / s·m. 2 (Equivalent to a rainstorm level of 108 mm / h), taking the flow velocity inside the umbrella shaft as 1.0 m / s, then:

[0029] The maximum flow rate into the umbrella pole per unit time is:

[0030] Q≈0.03×4.91=0.147L / s=0.000147m 3 / s;

[0031] Minimum inner diameter of umbrella pole:

[0032] d≈[4×0.000147 / (π×1.0)]0.5≈0.0137m≈13.7mm,

[0033] This needs to be multiplied by a certain safety factor before it can be used in practice.

[0034] Working principle: such as Figure 3 As shown, when rainfall occurs, rainwater enters the concave-facing umbrella surface 1 and is guided to the central area along the inclined guide surface on the inner side of the umbrella surface 1. Supported by the umbrella ribs 2 and the inclined umbrella rod 3, the rainwater converges at the hollow drainage umbrella rod 4. At the top of the hollow drainage umbrella rod 4, a drip-proof device 5 prevents external water droplets from falling, and a filter screen 6 (annular mesh structure) is located at the connection between the inclined umbrella rod 3 and the hollow drainage umbrella rod 4, effectively blocking impurities from entering. Rainwater flows into the interior of the hollow drainage umbrella rod 4 through the drainage holes 502 distributed around the water collection baffle 501, and, with the help of gravity, is guided from the underground drainage pipe connection port 7 at the bottom of the umbrella rod into the underground drainage pipe 8, forming a complete drainage channel. Throughout the process, rainwater flows orderly along the umbrella surface 1 and the umbrella rod structure, achieving efficient collection and discharge, reducing the burden of surface runoff, reducing rainwater splashing, and, combined with the rainwater harvesting system, can be used for greywater reuse.

[0035] Therefore, this utility model adopts a fixed upward-opening water-collecting and guiding umbrella with the above-mentioned structure, which realizes rainwater collection, guidance and discharge in one, effectively solves the problem of rainwater splashing in public places, improves the utilization rate of rainwater resources, reduces the urban drainage burden, and has both aesthetics and practicality.

[0036] It should be pointed out finally: the above examples are only the preferred specific embodiments of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art in the technical field disclosed by the present application, according to the technical scheme of the present application and the utility model concept, equivalent replacement or change, should be covered in the protection scope of the present application.
