Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Example Reference Figures 1-5 This is an embodiment of the present invention, which provides a giant sun umbrella that collects rainwater and prevents rainwater splashing, comprising: The load-bearing mechanism 100 includes a column 110, an auxiliary functional component 120 disposed on the outside of the column 110, a support component 130 disposed at the bottom of the column 110 in contact with the ground, and a drain pipe 140 fixedly installed in the inner cavity of the column 110. The sunshade mechanism 200 includes a hollow column 210 fixedly installed on the top of the column 110, a double-layer linkage umbrella rib 220 hinged to the top of the hollow column 210, a main umbrella surface 230 fixedly installed on the top of the double-layer linkage umbrella rib 220, and a support umbrella rib 240 hinged to the center of the top of the double-layer linkage umbrella rib 220. The drain pipe 140 coaxially passes through the axial cavity of the column 110, and its top end forms a sealed flange connection with the central water receiving part of the main umbrella surface 230.

[0020] The coaxial drainage pipe 140 inside the column 110 is connected to the sealed flange of the main umbrella surface 230, ensuring a continuous flow path for rainwater from the center of the umbrella surface to the ground, thus avoiding the problem of disorderly splashing of rainwater in traditional sun umbrellas. The hinged structure of the double-layer linkage umbrella ribs 220 and the hollow column 210 provides an axially connected spatial channel for the drainage system while ensuring the stable unfolding of the umbrella surface.

[0021] Specifically, the sunshade mechanism 200 also includes a secondary umbrella surface 250 fixedly installed on the top of the supporting umbrella rib 240, a drainage channel 260 opened on the outside of the hollow column 210, and a sealing sleeve 270 fixedly sleeved on the outside of the hollow column 210.

[0022] The secondary canopy 250 intercepts splashed water droplets from the edge of the main canopy 230, while the drainage channel 260 directs the condensate adhering to the surface of the hollow column 210 outwards. The sealing sleeve 270 effectively prevents rainwater from seeping into the hinge of the umbrella ribs. The combination of these three components significantly improves the robustness of the anti-drip system, making it suitable for heavy rain conditions and solving the problem of edge overflow of a single-layer canopy under extreme precipitation.

[0023] Furthermore, the auxiliary functional component 120 includes a mounting base 121 fixedly installed on the top of the column 110, and an illumination lamp body 122 fixedly installed on the outside of the mounting base 121. The auxiliary functional component 120 also includes a searchlight body 123 fixedly installed on the outside of the mounting base 121, and a scrolling screen 124 fixedly installed on the bottom of the mounting base 121 and arranged in a ring on the outside of the column 110.

[0024] The integrated design of the mounting base 121 and the lighting body 122 not only provides basic sunshade functionality but also expands nighttime lighting capabilities. The mounting base 121 serves as an installation platform for the functional modules, and its top positioning structure ensures that the light projection angle of the lighting body 122 is not affected by the opening and closing of the umbrella. The spatial separation of the lighting body and the drainage system avoids the risk of moisture damage to the electrical system, making the sunshade umbrella usable in all weather conditions and suitable for places such as commercial plazas that require continuous lighting. The addition of the searchlight body 123 and the scrolling screen 124 gives the sunshade umbrella multimedia interactive features. The searchlight body 123 provides directional strong light illumination, and the scrolling screen 124 achieves 360° information display through a ring distribution. The modular connection between the two and the mounting base 121 facilitates functional expansion and maintenance.

[0025] Preferably, the support mechanism 100 further includes a filter assembly 150 disposed in the inner cavity of the support assembly 130, and a ventilation grille 160 fixedly installed on the outside of the column 110. The support assembly 130 includes a support shell 131 fixedly installed on the bottom of the column 110, a rectangular groove 132 opened inside the support shell 131, a drain hole 133 opened at the bottom of the support shell 131, and a ventilation groove 134 opened on the outside of the support shell 131.

[0026] The filter assembly 150 and the ventilation grille 160 constitute the umbrella self-maintenance system. The filter assembly 150 separates impurities from the collected rainwater to prevent the drain pipe 140 from being blocked. The ventilation grille 160 promotes air exchange inside and outside the column 110 and avoids negative pressure generated by the closed rectangular groove 132, which affects the opening and closing of the umbrella. This structure greatly reduces the frequency of facility maintenance and is suitable for areas with a lot of dust or high humidity. The multi-functional cavity design of the support shell 131 achieves a balance between structural strength and drainage efficiency. The rectangular groove 132 provides installation space for the filter assembly 150. The drainage hole 133 and the ventilation groove 134 form a bottom cross airflow, which accelerates rainwater discharge and prevents ground water back seepage.

[0027] Furthermore, the filter assembly 150 includes a box 151 that is movably engaged in the rectangular groove 132, a slot 152 formed on the inner wall of the box 151, a filter screen 153 that is movably engaged in the inner cavity of the slot 152, a limiting plate 154 fixedly installed on the outside of the filter screen 153, and a handle 155 fixedly installed on the outside of the limiting plate 154.

[0028] The drawer-type structure of the filter assembly 150 significantly improves maintenance convenience. Through the cooperation of the slot 152 and the limiting plate 154, the filter screen 153 can be quickly removed and cleaned. The non-slip design of the handle 155 facilitates application of force by operators in wet environments. This design effectively reduces the time required for daily maintenance of the rainwater filtration system.

[0029] It should be noted that the curved surface of the main umbrella 230 is prestressed to form an inverted conical drainage topology, and its radius of curvature decreases from the edge to the center, so that surface rainwater can achieve directional convergence under the condition that the contact angle is less than 15°.

[0030] The inverted conical drainage topology of the main umbrella surface 230 achieves zero residual drainage through fluid dynamics optimization. Its gradual curvature design allows rainwater to autonomously converge towards the center under the action of surface tension, completely eliminating the phenomenon of water accumulation on the umbrella.

[0031] During use, when rainfall occurs, the inverted conical curved surface structure of the main umbrella 230 causes rainwater to flow towards the center along the curvature gradient, and enters the coaxial drain pipe 140 through the sealed flange connection. At the same time, the secondary umbrella 250 intercepts splashed water droplets at the edges, and the drainage channel 260 drains condensate from the surface of the column. Under the action of gravity, the rainwater flows vertically down the drain pipe 140 to the cavity of the support shell 131. After being filtered for impurities by the filter screen 153, it is discharged into the municipal pipe network through the drain hole 133. The convection formed by the ventilation slot 134 and the ventilation grille 160 prevents the cavity from becoming damp. During this process, the lighting body 122 and the searchlight body 123 on the fixed base 121 keep working around the clock, and the scrolling screen 124 displays information around the perimeter. The various functional modules achieve parallel operation of the hydraulic system and the electrical system through structural isolation.

[0032] In summary, the cooperation between the supporting mechanism 100 and the shading mechanism 200 forms a three-level rainwater management system. The inverted conical drainage topology of the main umbrella surface 230 achieves primary rainwater collection, the secondary umbrella surface 250 constitutes a secondary splash barrier, and the drain pipe 140 and filter assembly 150 complete the final purification and discharge. The modular layout of the auxiliary functional components 120 spatially isolates the lighting body 122, searchlight body 123, and scrolling screen 124 from the drainage system, ensuring electrical safety and enabling functional expansion. The rectangular groove 132 design of the support component 130, together with the ventilation grille 160, forms an active air circulation, effectively solving the problem of moisture and corrosion in large umbrella structures.
