Technical Field

[0001] The utility model relates to the technical field of water conservancy grille covers, in particular to a water conservancy grille. Background Art

[0002] Urban water conservancy projects are water conservancy projects carried out to solve urban flood control, water supply, drainage and urban wastewater treatment. In the pedestrian and vehicle areas of garden landscapes or roads, drainage systems are often arranged at intervals. They mainly use drainage ditches and drainage grille covers to achieve water drainage. The current drainage facilities have stainless steel or galvanized grille covers. The transverse and longitudinal ribs are fixed by welding. The surface forms a rectangular drainage hole, which discharges rainwater into the drainage ditch through the drainage holes.

[0003] There are still some problems when using the existing grille cover:

[0004] 1. There are many welding points between the transverse and longitudinal ribs of the grille cover, which is not beautiful;

[0005] 2. The horizontal and longitudinal ribs of the grille cover are in a vertical plate structure, and its top cross-section is small. When used in parks or squares, when pedestrians step on the grille cover, the small cross-section will cause great force on the feet and discomfort. In severe cases, it may also injure the pedestrians' feet or shoes, resulting in a poor customer experience. Based on this, a water conservancy grille is provided. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By setting up a grille assembly, through the curved part above the curved support spacer and the "Ω"-shaped structure of the curved support spacer, the contact area is larger when pedestrians step on the grille. Compared with the traditional grille cover structure in which the horizontal and longitudinal ribs are vertical plates, the squeezing force on the pedestrian's feet can be effectively reduced, making it safer to use and effectively improving the user experience.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 6 In an embodiment of the present invention, a water conservancy grille includes a rectangular outer frame 1, a grille assembly 2, and the grille assembly 2 includes a wave-shaped grille plate 201, a bottom drain port 202, a first side drain port 203, and a second side drain port 205;

[0027] The corrugated grating plate 201 is welded and fixed to the inner side of the rectangular outer frame 1. The bottom drain port 202 is provided in the arc-shaped portion below the corrugated grating plate 201 and completely passes through the bottom of the corrugated grating plate 201. The first side drain port 203 and the second side drain port 205 are respectively provided in the vertical portion of the corrugated grating plate 201 and completely pass through both sides of the vertical portion.

[0028] Drainage is achieved through the bottom drain port 202, the first side drain port 203, and the second side drain port 205. At the same time, the bottom curved portion of the wave-shaped grating plate 201 is used to intercept large particles of impurities. The top curved portion of the wave-shaped grating plate 201 effectively increases the contact surface between the wave-shaped grating plate 201 and pedestrians' feet, thereby reducing the squeezing force on pedestrians' feet.

[0029] An arc-shaped support spacer 204 extending to the concave area of the corrugated grating plate 201 is fixed to the inner side of the first side drain outlet 203, and the top of the arc-shaped portion of the arc-shaped support spacer 204 is flush with the top of the arc-shaped portion above the corrugated grating plate 201 and the top of the rectangular outer frame 1;

[0030] A snap-fitting notch 207 is formed on the vertical portion of the corrugated grating plate 201 above the second side drain outlet 205, and a limiting piece 206 is formed by the snap-fitting notch 207 and the second side drain outlet 205.

[0031] The horizontal cross-section of the arc-shaped support spacer 204 is in an "Ω" shape. The lateral portion of the arc-shaped support spacer 204 away from the first side drain outlet 203 is inserted into the inner side of the snap-fitting groove 207. The limiting piece 206 is used to provide support for the arc-shaped support spacer 204.

[0032] There are multiple groups of bottom drain outlets 202, first side drain outlets 203, arc-shaped support spacers 204, second side drain outlets 205, limiting plates 206, and snap-in grooves 207 evenly arranged along the longitudinal direction of the corrugated grating plate 201, and the bottom drain outlets 202 and the first side drain outlets 203 and the arc-shaped support spacers 204 are staggered along the longitudinal direction.

[0033] In this embodiment: It should be noted that: this grille is mainly used for drainage ditches in parks, squares and other places;

[0034] When in use, the grid-like structure composed of multiple arc-shaped support spacers 204 and the corrugated grid plate 201 can realize rainwater drainage operation through the bottom drain port 202, the first side drain port 203, and the second side drain port 205, and the lower arc portion of the corrugated grid plate 201 can intercept large particles of impurities;

[0035] At the same time, the arc-shaped portion above the arc-shaped support spacer 204 and the "Ω"-shaped structure of the arc-shaped support spacer 204 provide a larger contact area when pedestrians step on the grille. Compared with the traditional grille cover structure in which the horizontal and vertical ribs are vertical plates, this can effectively reduce the squeezing force on the pedestrian's feet, making it safer to use and effectively improving the user experience.

[0036] It should also be noted that the limiting piece 206 supports the bottom of one side of the arc-shaped support piece 204, and the arc-shaped support piece 204 and the wavy grille plate 201 squeeze and limit each other, so that the grille assembly 2 as a whole has strong pressure resistance and can meet the safety requirements of pedestrians.

[0037] Please refer to Figures 1-2 Cleaning openings 3 are provided at positions where both ends of the outer wall of the rectangular outer frame 1 are aligned with the arc-shaped portion below the wave-shaped grid plate 201 .

[0038] In this embodiment: when a large amount of impurities accumulate on the inner side of the arc-shaped portion below the wavy grating plate 201, the grating can be taken out as a whole with the cleaning port 3 facing downward. Then, a tool can be used to scrape and clean the inner side of the arc-shaped portion below the wavy grating plate 201. The impurities can fall out through the cleaning port 3 or the top opening of the wavy grating plate 201, thereby achieving the impurity cleaning operation.

[0039] Please refer to Figures 1 to 6 The bottom drain outlet 202, the first side drain outlet 203, the arc-shaped support spacer 204, the second side drain outlet 205, the limit plate 206, and the snap-in groove 207 are formed by punching and stamping of steel plates, and the wavy structure of the wavy grid plate 201 is formed by a stamping and bending process.

[0040] In this embodiment, when the grille assembly 2 is produced and processed, the bottom drain port 202, the second side drain port 205, the limiting piece 206, and the snap-in slot 207 are sequentially formed on the steel plate by a punching process, and then the first side drain port 203 and the arc-shaped supporting spacer 204 are formed by a stamping process. Finally, the steel plate is bent into a wave structure by a stamping and bending process.

[0041] The overall structural forming process is simple and does not require welding. Finally, the grille assembly 2 is welded and fixed to the rectangular outer frame 1. This welding is concentrated on the lower surface of the wave grille plate 201, so that the entire grille has no welding points when viewed from above, and the overall appearance is more beautiful.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
