[0002] The traditional water inlet collects rainwater from the road through rainwater grilles and flows it into the rainwater pipe network. However, in the process of rainwater collection, the water body will be mixed with road garbage such as leaves, fruit cores, mud, plastic bags, etc. If it is not cleaned in time, it will easily cause pipe blockage, and in severe cases it will lead to urban flooding.

[0003] In order to solve the above problems, the prior art provides the following pollution blocking measures on the rainwater outlet:

The water flow guide bottom plate is arranged at the open end of the water flow guide side plate assembly, and is respectively connected to the first side plate and the second side plate. A gap is provided between the water flow guide bottom plate and the connecting plate to form a sedimentation bag mounting groove, and the rainwater filtration sedimentation bag is installed in the sedimentation bag mounting groove.

[0005] CN202020572481.4 discloses a concrete vertical single-grate rainwater inlet structure, which includes a base, a well wall, a rainwater inlet connecting pipe, a manhole cover, and a hanger; the base is constructed with a well wall on the top surface, and the bottom of the well wall is opened with circular holes around, and the rainwater inlet connecting pipe runs through the circular holes; a manhole cover seat is constructed on the top of the well wall, and a circle of grooves is arranged on the top of the manhole cover seat toward the center, and the manhole cover is placed in the groove; a leveling stone is constructed on one side of the manhole cover seat, and the top surface of the leveling stone is provided with a slope toward the center of the well wall, and a water inlet channel is arranged on the corresponding manhole cover seat, and a vertical grate is arranged on the upper cover of the water inlet channel opening; a hanger is installed on the manhole cover, and the four sides of the hanger are provided with upward convex limiting edges, and vertical hanging rods are connected to both sides of the hanger, and the top end of the hanging rod is bent and inserted into the gap between the manhole cover and the manhole cover seat; a sewage interception hanging basket is placed on the hanger.

[0033] like Figure 1-Figure 5As shown, a sewage intercepting vertical rainwater inlet comprises a base 2 fixed to the top of a well chamber 1, a top cover 3 opened and closed on the base 2, and a water inlet grate 6 arranged on one side of the base 2, and also comprises an active sewage intercepting mechanism, the active sewage intercepting mechanism comprises a telescopic sewage clamping unit 4 arranged at the bottom end of the base 2 and a water-driven sewage crushing unit 5 linked to the telescopic sewage clamping unit 4, a sewage collecting basket 7 is hung below the telescopic sewage clamping unit 4, and the sewage collecting basket 7 in this embodiment is hung on the base 2 by a hanging rope and a hanging ring, so that after opening the top cover 3, the sewage collecting basket 7 can be pulled out to pour out the pollutants.

[0034] The telescopic dirt clamping unit 4 includes a horizontal telescopic hydraulic cylinder fixed to the bottom end of the water inlet grate via a suspension rod 44 and a telescopic clamping assembly connected to the piston rod of the horizontal telescopic hydraulic cylinder. The telescopic clamping assembly is also linked to the water-driven dirt crushing unit. The telescopic clamping assembly includes a sliding rod 43 connected to the horizontal telescopic hydraulic cylinder 41 at one end and a connecting block 47 fixedly connected to the other end of the sliding rod 43. The bottom end of the connecting block 47 is horizontally rotatably connected with a positioning clamp 48. One end of the positioning clamp 48 is slidably connected to a guide groove 461 provided on a guide plate 46 via a guide head, and a clamping head is provided at the other end. The guide plate 46 is fixed to the outer circumference side of the guide cylinder 45, and a guide groove 461 is provided at the top end of the guide plate 46. The guide groove 461 includes an inclined section 4611 and a horizontal section 4612 that are connected to each other. The inclined section 4611 and the horizontal section 4612 are sequentially arranged from the horizontal telescopic hydraulic cylinder 41 to the connecting block 47, and the inclined section 4611 extends outward near one end of the horizontal telescopic hydraulic cylinder 41. The water-driven garbage crushing unit 5 includes a connecting rod 53 with one end horizontally rotatably connected to the bottom end of the connecting block 47, a sliding block 52 horizontally rotatably connected to the other end of the connecting rod 53, and a water-driven cutting assembly 51 arranged on the sliding block 52. The sliding block 52 is slidably arranged on an arc-shaped slide rail 54, and the arc-shaped slide rail 54 is fixed on the inner wall of the well chamber 1 below the water inlet grate 6.

[0035] The water-driven cutting assembly 51 includes a second water-driven impeller 511 vertically rotatably disposed at the top of the slider 52 and a cutter 512 fixed to the blade edge of the second water-driven impeller 511 .

[0036] In this embodiment, it is configured as follows: when the positioning clamp 48 extends from the side of the base 2 below the water inlet grate 6 to clamp large pieces of pollutants, the water drives the waste crushing unit 5 to move away from the positioning clamp 48; when the positioning clamp 48 retracts to clamp the large pieces of pollutants into the water inlet grate 6, the positioning clamp 48 opens, and at the same time, the water drives the waste crushing unit 5 to move in the direction of the positioning clamp 48, and under the action of the water flow, the second water-driven impeller 511 drives the cutter 512 to rotate, and the clamped large pieces of pollutants are cut off by the cutter 512, and the cut pollutants fall into the waste collecting basket 7 under the action of their own gravity, and the operation is cyclically operated until the large pieces of pollutants are completely chopped up to avoid clogging the water inlet grate 6.

[0037] Two water-driven cutting assemblies 51 are slidingly arranged on the arc-shaped slide rail 54 and at positions symmetrical to the connecting block 47. The cutters 512 of the two water-driven cutting assemblies 51 are arranged alternately, and the length of the cutter 512 is not less than the length of the inclined section 4611. The alternately arranged cutters 512 are convenient for cutting large pieces of pollutants that are blocked in front of the water inlet grate 6 into small pieces, and then the small pieces of pollutants fall into the sewage collecting basket 7 under the action of their own gravity and water flow.

[0038] The water inlet grate 6 includes a corrugated trash-blocking plate vertically slidably arranged on the side of the base 2, and the corrugated trash-blocking plate is fixedly connected to the base 2 via positioning bolts. The top cover 3 is fixed to the top of the base 2 via embedded bolts, and the top cover 3, the base 2 and the corrugated trash-blocking plate are all made of ductile iron. Patterns are carved on the corrugated trash-blocking plate and the top.

[0039] Working principle: When water accumulates on the road surface, under the action of the terrain difference, water flows through the water inlet grate 6 into the well chamber 1, and then is discharged through the drainage pipe connected to the well chamber 1. In this process, small pieces of pollutants are directly intercepted by the sewage collecting basket 7, and large pieces of pollutants accumulate on the water inlet grate 6. At this time, the horizontal telescopic hydraulic cylinder 41 is started to drive the sliding rod 43 to extend and retract. While the sliding rod 43 drives the positioning clamp 48 to extend, the guide head on the positioning clamp 48 moves from outside to inside along the inclined section 4611 until the positioning clamp 48 extends out of the water inlet grate 6. At this time, the positioning clamp 48 clamps the large pieces of pollutants accumulated on the water inlet grate 6, and then the sliding rod 43 drives the positioning clamp 48 to retract, and during the retraction process, the large pieces of pollutants are clamped into the water inlet grate 6. The positioning clamp 48 opens, and at the same time drives the water-driven cutting assembly 51 to move in the direction of the positioning clamp 48 to cut off the clamped large pieces of pollutants, and the cycle action is repeated until the large pieces of pollutants (flexible plastic bags) are completely shredded, thereby avoiding the large pieces of pollutants blocking the water inlet.

[0040] Therefore, the present invention adopts the above-mentioned structure of the sewage intercepting vertical rainwater inlet. By setting up an active sewage intercepting mechanism, the pollutants that block the water inlet grate side can be clamped and crushed and collected, avoiding the blockage caused by the accumulation of pollutants at the water inlet, thereby effectively alleviating urban waterlogging.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
