Abstract
Gradually-opening spiral line grate well lid belongs to municipal water supply and drainage technical field, including base, setting boss that puts at the base central point and use the boss as the protruding muscle of central axial array on the base, protruding muscle is gradually-opening formula spoke structure, sets gradually the base hole that leaks on the groove structure that forms between adjacent protruding muscle from inside to outside, sets gradually protruding muscle hole that leaks on protruding muscle from inside to outside, the base hole area that leaks and protruding muscle hole that leaks grow in proper order from inside to outside. Through improving the overall structure to the well lid, improve well lid drainage efficiency, the pleasing to the eye of reinforcing well lid.
Description
Technical Field
The utility model belongs to the technical field of municipal administration plumbing, concretely relates to involute helix comb well lid.
Background
The collection and the discharge of rainwater are important links in municipal water supply and drainage systems, and with the proposal of the concept of 'sponge city', urban construction design practitioners pay more attention to the collection and the discharge of rainwater. In a municipal water supply and drainage system, a structure for rainwater to flow into on a road surface is called a rainwater port, a rainwater grate is covered above the rainwater port and is used for preventing foreign matters from falling and pedestrians from falling, and the design principle of the rainwater port and the rainwater grate is radial flow as large as possible and blocking rate as small as possible.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a gradually-opened helix comb well lid, improve through the overall structure to the well lid, improve well lid drainage efficiency, strengthen the pleasing to the eye of well lid.
The utility model adopts the technical proposal that: gradually-opening spiral line grate well lid, including the base, set up the boss that puts at the base central point and use the boss as the protruding muscle of central axial array on the base, protruding muscle is gradually-opening line formula spoke structure, sets gradually the base hole that leaks on the groove structure that forms between adjacent protruding muscle from inside to outside, sets gradually protruding muscle hole that leaks on protruding muscle from inside to outside, the hole area in base hole that leaks and protruding muscle hole that leaks is the grow in proper order from inside to outside.
Furthermore, reinforcing ribs are arranged on the bottom surface of the base between the water leakage holes of the base and the water leakage holes of the convex ribs, the reinforcing ribs are involute spoke structures, and the reinforcing ribs are axially arrayed to form a turbine structure by taking the central shaft of the base as the center.
Further, the base, the boss and the convex rib are integrally cast and formed, and the heights of the boss and the convex rib are equal.
Further, the boss is annular.
Furthermore, the number of the convex ribs is 8-14, and the number of the reinforcing ribs is the same as that of the convex ribs.
Further, the total hole area of the base water leakage holes and the convex rib water leakage holes is larger than 1/5 of the area of the base.
Adopt the utility model discloses the beneficial effect who produces: through improving the overall structure to the well lid, improve well lid drainage efficiency, the pleasing to the eye of reinforcing well lid.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a bottom schematic view of the present invention.
Detailed Description
Referring to the attached drawings 1-2, the gradually-opened spiral grate well cover comprises a base 1, a boss 2 arranged at the center of the base 1 and a convex rib 3 axially arrayed on the base 1 by taking the boss 2 as a center, wherein the convex rib 3 is an gradually-opened spoke structure, a base water leakage hole 4 is sequentially arranged on a groove structure formed between adjacent convex ribs 3 from inside to outside, a convex rib water leakage hole 5 is sequentially arranged on the convex rib 3 from inside to outside, and the hole areas of the base water leakage hole 4 and the convex rib water leakage hole 5 are sequentially enlarged from inside to outside. The bottom surface of the base 1 between the base water leakage hole 4 and the convex rib water leakage hole 5 is provided with a reinforcing rib 6, the reinforcing rib 6 is of an involute spoke structure, and the reinforcing rib 6 forms a turbine structure by taking the central shaft of the base 1 as a central axial array.
The base 1, the boss 2 and the convex rib 3 are integrally cast and formed, and the height of the boss 2 is equal to that of the convex rib 3. The boss 2 is circular.
The number of the convex ribs 3 is 8-14, and the number of the reinforcing ribs 6 is the same as that of the convex ribs 3.
The total hole area of the base water leakage holes 4 and the convex rib water leakage holes 5 is larger than 1/5 of the base area.
In specific implementation, when shallow water exists, the water leakage holes 4 of the base leak water; in deep water, the base water leakage holes 4 and the convex rib water leakage holes 5 leak water simultaneously, and the involute spiral line grooves form vortex; the vertical projection area of the base water leakage holes 4 and the convex rib water leakage holes 5 accounts for about 20 percent of the well lid. Referring to the specific embodiment of the attached figure 1, the well cover is composed of a base 1, convex ribs 3, a boss 2, base water leakage holes 4 and convex rib water leakage holes 5, the whole body is in an equally divided array spiral shape, the convex ribs 3 are 10, 100 water leakage holes are arranged, wherein the round base water leakage holes and the strip-shaped base water leakage holes are arranged on the base 1
Each convex rib 3 is provided with circular water leakage holes
And (4) respectively.
