The first embodiment is as follows:

referring to fig. 1, a road surface drainage device is provided under a road surface, and includes: a cover body 100, a sundries filtering chamber 200 and a water drainage tank 300 which are arranged from top to bottom, wherein the cover body 100 is provided with water leakage holes (not shown) for water to penetrate; the drainage channel 300 is connected with a sewage pipeline for drainage; the impurity filtering chamber 200 is provided therein with a filtering member 220 for filtering impurities.

A stop 310 is arranged above the drainage channel 300, the shape and size of the stop 310 are not specifically set, the stop 310 is connected with the side wall of the impurity filtering chamber 200 through a connecting piece 210, specifically, in the embodiment, the connecting pieces 210 are circumferentially distributed along the vertical axis of the impurity filtering chamber 200, and the number of the connecting pieces 210 is 4; in this embodiment, the filtering member 220 is disposed in cooperation with the connecting member 210, specifically, as shown in fig. 3-4, the filtering member 220 is a filtering barrel, the side surface of the filtering barrel is provided with a limiting groove 221 for cooperating with the connecting member 210, the filtering barrel is provided with a through hole 222, and the upper portion of the through hole 222 located on the inner surface of the filtering member 220 is provided with a barb 223 for assisting in fixing the impurities, so as to prevent the impurities from being accumulated at the bottom of the filtering barrel, and the impurities should be poured out in time when the filtering barrel is filled with the impurities, it should be noted that the filtering barrel is only a solution of the filtering member 220 in this embodiment, and in other.

Referring to fig. 1, the upper surface of the stopper 310 forms a zigzag space 320 with the upper surface of the drain groove 300; the folded space 320 is communicated with the sundries filtering chamber 200 and the drainage tank 300; in the contact surface of the reverse-folded space 320, the highest point of the upper surface of the stopper 310 is higher than the lowest point of the upper surface of the drain tank 300, so that the whole reverse-folded space 320 forms a completely sealed water storage tank, and the space between the impurity filtering chamber 200 and the drain tank 300 is sealed by the completely sealed water storage tank, thereby preventing odor in the sewage pipes from being emitted and insects from climbing out; specifically, in this embodiment, the whole zigzag space 320 is formed by combining two arc ends, and the arc is used to reduce the water flow resistance in the whole zigzag space 320, it should be noted that such arc is not certain, and under the functional requirement of the water storage tank is satisfied, a 90-degree zigzag manner may also be adopted to seal, of course, the whole zigzag space 320 may be arranged around the stopper 310 or be arranged discontinuously around the stopper 310, and the arrangement of the discontinuous around stopper 310 means that the whole zigzag space 320 may be locally and directly connected with the upper surface of the water drainage tank 300 to form a plurality of zigzag spaces 320.

Example two:

this embodiment is generally consistent with the first embodiment, and the differences are as follows:

the device is suitable for the ground containing a large amount of silt or granular impurities, and is also provided with a first sedimentation tank 400, wherein the first sedimentation tank 400 is positioned on the side surface of the impurity filtering chamber 200 and below the road surface; the depth of the first sedimentation tank 400 is more than or equal to that of the impurity filtering chamber 200, so that sedimentation of silt is ensured; the upper part of the first settling pond 400 is communicated with the upper part of the impurity filtering chamber 200 through a pipeline 420; the upper part of the first sedimentation tank 400 is contacted with the ground through a water permeable cover 410, and the water permeable cover 410 is provided with water permeable holes (not shown) for water permeability; the aperture of the hole of permeating water (not shown in the figure) is greater than the aperture that leaks the hole (not shown in the figure), guarantees that the sewage that contains silt and large granule flows into the sedimentation tank earlier, in flowing into debris filter chamber 200 through the sedimentation tank, avoids silt direct flow to debris filter chamber 200 in, probably causes the jam.

Specifically, in this embodiment, still be equipped with the blowdown bucket (not shown in the figure) in the first settling basin 400, will subside the silt in first settling basin 400 through the blowdown bucket and take out, conveniently empty.

In addition, a second settling tank (not shown) may be provided for settling the sediment, and the second settling tank may have the same structure as the first settling tank 400 and be arranged symmetrically to the first settling tank 400.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
