For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence with the upper, lower, left and right directions of the drawings, and do not limit the structure.

As shown in fig. 1-2, the rainwater grate 1 provided in this embodiment includes a floating ball 2, a well cover 3, a grating 4, a well ring 5, a mounting hole 6, an attachment ring 7, a pillar 8, a filter bin 9, a mounting block 10, a hinge 11, a storage chamber 12, a hole 13, a hauling rope 14, an access hole 15, a water outlet 16, and a water inlet 17.

The well ring 5 is provided with a plurality of mounting holes 6, and the mounting holes 6 are waist-shaped holes. During installation, an outer countersunk groove (the caliber of the countersunk groove is larger than that of the wellhead) is formed in the upper end of the wellhead of the pavement, the well ring is placed on the upper end face of the countersunk groove, and the part below the well ring is located in the wellhead. And then concrete is poured into the countersunk groove to fix the walling crib 5. And concrete is filled in the mounting hole 6, so that the stability of the fixing structure is improved. Thus, the well ring 5 of the mounted rainwater grate 1 is positioned in the mounting hole below the road surface. The well lid 3 covers and locates on the walling crib 5. The top of installation piece 10 with well lid 3 fixed connection, the bottom pass through hinge 11 with curb 5 is connected. The mounting block 10 is of a square structure, and besides a round hole for placing the well cover 3 is arranged on the road surface for mounting the rainwater grate, a square hole for placing the mounting block 10 needs to be arranged beside the round hole. The setting of installation piece 10 can play the fixed action to the rainwater grate, places it and rotates in the round hole, because of well lid 3 connects structure as an organic whole through installation piece 10 again, plays the theftproof effect to well lid 3.

The lower end of the well ring 5 is provided with an attachment ring 7. The support column 8 is connected with the attachment ring 7, and the support column 8 is uniformly distributed on the circumference. A plurality of the supporting columns 8 enclose a bowl-shaped filtering bin 9 with a large upper part and a small lower part. On the bowl-shaped side wall, a plurality of said struts 8 form between them water outlets 16. The bottom of the bowl shape is connected with a storage chamber 12, and the storage chamber 12 is communicated with the filter bin 9. The side wall of the storage chamber 12 is provided with a plurality of holes 13 for draining water in an array mode, and the bottom of the storage chamber 12 is not communicated and used for storing garbage.

The well lid 3 is provided with an access hole 15, a plurality of concentric grids 4 and a plurality of water inlets 17. A plurality of said water inlets 17 are circumferentially distributed between each two grids 4. The structure and the size of the water inlet 17 need to meet the following requirements: firstly, a convenient floating ball 2 is arranged on the floating ball; secondly, a gap which is convenient for water flowing is reserved between the floating ball 2 and the floating ball after the floating ball is placed on the water draining device, so that water can be drained when the floating ball does not float upwards in case of light rain. Every all connect one on the floater 2 haulage rope 14, haulage rope 14 is connected with well lid 3. The floating ball 2 is a hollow ball and can float upwards along with rainwater when meeting rainstorm. The floating ball 2 is made of materials which need to be floated by considering rainwater energy and sink without water energy and are easy to replace after being broken. As shown in fig. 3, when the floating ball 2 is placed on the well lid 3, the grid 4 is embedded, and the height of the grid 4 exceeds the floating ball 2.

Under the condition of small rainfall, the floating ball 2 has small floating degree and can hardly float, and rainwater flows into the rainwater pipe network from the grille 4 and the water outlet 16.

Under the condition of heavy rainfall, the fine garbage flows to the rainwater grate 1 along with the rainwater. At this time, the floating ball 2 floats upwards to a medium height, and rainwater flows into the filtering bin 9 through the grating 4 and the water inlet 17 and finally flows into the storage chamber 12. The rainwater flows into the rainwater pipe network through the holes 13, and the garbage is stored in the storage chamber 12. After the rainfall stops, the floating ball 2 falls back onto the water inlet 17.

Under the condition of rainstorm, large-particle garbage and small-particle garbage flow to the rainwater grate 1 along with rainwater. At this time, the floating ball 2 floats upwards completely (as shown in fig. 4), the water inlet 17 is opened completely, so that garbage and rainwater can smoothly enter, and the phenomenon that the garbage covers the surface of the rainwater grate to lose the drainage function is avoided.

When the rainwater grate 1 is maintained (usually, sunny days are selected), the manhole cover 3 is opened at the position of the manhole 15 by a crowbar, and then a sewage suction pipe orifice of a sewage suction truck extends into the storage chamber to suck out the garbage in the storage chamber.

In addition, it is necessary to conduct certain research on different regions to determine the approximate particle size of the fine solid waste in different regions, such as cement-based roads and asphalt-based roads, and surrounding residential areas or commercial areas, etc., and to customize the size of the holes 13 according to different particle size requirements to ensure that the waste does not flow into the rainwater pipe network.
