The inner wall of the outer frame 1 is fixed with a supporting beam 16, the upper end of the supporting beam 16 is rotatably connected with two symmetrically arranged ball screws 17, the circumferential side walls of the two ball screws 17 are both in threaded connection with sliding sleeves 18, the ball screws 17 do not have self-locking capacity, so that the sliding sleeves 18 can move downwards under the action of gravity, the circumferential side walls of the two ball screws 17 are both fixed with a plurality of groups of rotating vanes 19, the rotating vanes 19 can intercept filiform matters in the water flow drainage process, accumulation and blockage are avoided, the supporting frame 3 and the sliding sleeves 18 can be taken down, so that the rotating vanes 19 can be conveniently cleaned, a certain filtering function is realized, the tops of the two sliding sleeves 18 are both fixedly connected with the cross beams 4 at corresponding positions, the rotating vanes 19 are driven to rotate by the larger impact force of the water flow, so that the ball screws 17 rotate, the sliding sleeves 18 further push the cross beams 4 to, the effect of high-speed drainage is realized, and drainage can be timely realized during rainstorm.

The piece 15 of starting is the permanent magnet, and the floating block 14 is the cystosepiment, guarantees that floating block 14 can drive the piece 15 of starting to move up under the buoyancy effect, and the quantity of apopore 13 is less than the quantity of inlet opening 12 and the aperture of apopore 13 is less than the aperture of inlet opening 12, when guaranteeing that there is continuous rivers to enter externally, can not accumulate rivers in the measurement chamber 11, thereby guarantee to make the piece 15 of starting to move up when external rivers last to make 6 shrink of closing plate realize quick drainage.

In the invention, when no sewage, rainwater and the like pass through the water grate, each return spring 9 is in the original length, each closing plate 6 extends out of the corresponding sliding groove 5, and the next closing plate 6 is inserted into the sliding groove 5 on the previous cross beam 4, so that each cross beam 4 is combined into a closed platform, the upper part of the outer frame 1 is in a relatively closed state, the condition that articles of pedestrians are carelessly dropped and directly enter the inner part of the outer frame 1 to be taken out is avoided, and the accidental property loss of people is reduced;

when a small amount of rainwater and the like pass through the water grate, water flow firstly enters the measuring cavity 11 from the water inlet holes 12 and then flows out from the water outlet holes 13 at the bottom of the measuring cavity 11, and because the water inlet holes 12 are larger than the water outlet holes 13 in number and multiple pore diameters, when external water flow continuously enters the measuring cavity 11, the water flow in the measuring cavity 11 cannot be discharged in time so as to be accumulated in the measuring cavity 11, when the external water flow is not caused by continuous rainfall but artificially dumped sewage, the sewage quantity is small, the duration is short, so that when the sewage stops dumping, the measuring cavity 11 is not filled so that the sewage flowing along with time is slowly discharged through the water outlet holes 13, and the sealing plate 6 does not move in the whole process, so that the condition that dropped matters cannot be taken out by people when people dump is avoided;

when people continuously dump a large amount of sewage for a long time, the whole drainage process is like continuous rainfall, in this state, the water level in the measuring cavity 11 rises along with the gradual accumulation of water amount, so that the floating block 14 drives the starting block 15 to move upwards under the action of buoyancy, so that the starting block 15 moves upwards to the top of the measuring cavity 11, under this position, the starting block 15 generates magnetic repulsion to the magnetic blocks 10 on the close closing plate 6, so that the closing plate 6 close to the starting block 15 compresses the corresponding return springs 9 to slide towards the corresponding chutes 5 under the action of magnetic force, as the closing plate 6 moves, the magnetic blocks 10 on the closing plate 6 are driven to move towards the close other closing plate 6, so that the magnetic blocks 10 on one end of the closing plate 6 far away from the starting block 15 generate enough magnetic repulsion to the magnetic blocks 10 on the close other closing plate 6, so that the close other closing plate 6 moves into the corresponding chutes 5 under the action of the magnetic repulsion, therefore, linkage response is generated, all the closing plates 6 are contracted to the inner parts of the corresponding sliding grooves 5 under the action of magnetic repulsion force, so that larger gaps are formed among the cross beams 4, continuously flowing water flow is quickly beaten away from the gaps, and the condition that the road surface is polluted after the water flow spreads due to blockage is avoided;

when the rainfall is large, a large amount of rainwater cannot be timely drained only by means of the gap between the cross beams 4, in this state, the cross beams 4 reach the initial maximum drainage speed, the rainwater falls from the gap in a large amount and quickly, so that the rotating blades 19 are subjected to enough water flow impact force, the rotating blades 19 drive the ball screw rods 17 to rotate, the sliding sleeves 18 move upwards along with the rotating rods, the connected cross beams 4 and the support frames 3 are lifted, the upper parts of the outer frames 1 are all opened, a large amount of external rainwater can be quickly drained, road surface pollution caused by untimely water flow drainage is avoided, after the support frames 3 are lifted, water flow directly impacts the rotating blades 19 at high speed, when the external rainfall is continuously large, the rotating blades 19 are continuously impacted, so that the ball screw rods 17 continuously rotate until the support frames 3 are lifted to the highest position, in this state, the drainage quantity of the water grate reaches the maximum value and is enough to treat the drainage quantity of water flow caused by heavy rain, and after the drainage quantity is finished, the weight of the support frame 3 and the cross beam 4 pushes the sliding sleeve 18 to move downwards, so that the whole water grate is restored to the original state, the drainage speed is ensured in the rainfall process, and the property safety of pedestrians is protected in the non-rainfall process.
