In the process of lifting the lifting arc plate 41, the plurality of water inlets 410 on the lifting arc plate 41 sequentially introduce rainwater into the corresponding water inlet holes 203 and the corresponding backflushing holes 202 along the direction from top to bottom. Along the direction of keeping away from filter 2 axis, the recoil hole 202 that each filtration pore 201 corresponds recoil out the rainwater in proper order to this rainwater can be with blockking up the large tracts of land rubbish in corresponding filtration pore 201, and then has realized the mediation to filtration pore 201, ensures that the rainwater on the road surface can in time be discharged into in the secret drainage pipe, has played the effect of environmental protection.
Referring to fig. 3, 4 and 5, it is known that a plurality of water outlet holes are formed in a single pipe in the longitudinal direction thereof, and the strength of the fluid discharged from the water outlet holes is different from each other due to a loss of water pressure when the fluid flows in the pipe, and the strength of the fluid discharged from the water outlet holes is larger as the water outlet holes are closer to the water inlet end of the pipe.
In view of the above problems, the water inlets 410 of two vertically adjacent lifting arc plates 41 are spaced from each other, so that when the back flushing assembly controls rainwater to perform back flushing on large-area garbage blocked in the filter holes 201, only one back flushing hole 202 corresponding to one filter hole 201 performs back flushing action at the same time.
Through the above manner, when any one of the reverse punching holes 202 realizes the reverse flushing, the water pressure in the overflow water chamber 3 when the rainwater flows into the water inlet hole 203 is the maximum water pressure in the time, so that the rainwater in the reverse flushing hole 202 can flush the large-area garbage out of the filtering hole 201 with the maximum stiffness in the time, and further the reverse flushing effect on the large-area garbage is improved.
Referring to fig. 2, after the filter holes 201 are dredged, rainwater above the filter plates 2 is gradually discharged into the underground drainage pipe through the filter holes 201, the water level of the rainwater in the overflow water chamber 3 is gradually lowered, and the lifting arc plates 41 are gradually lowered by gravity.

The guide block 5 cooperates with the guide groove 101 to guide the lifting movement of the lifting arc plate 41.
Referring to fig. 3, the above-mentioned reverse punching 202 mainly functions to dredge the filter holes 201, and does not restrict the large-area garbage, so that the large-area garbage may repeatedly clog the filter holes 201.
Referring to fig. 2 and 6, in this regard, a rotary pipe 7 with an open bottom is vertically rotatably disposed on the filter plate 2, a plurality of water leakage holes 701 communicated with the inner cavity of the rotary pipe 7 are further formed on the pipe body above the filter plate 2, and a plurality of spiral impellers 8 are fixedly disposed in the rotary pipe 7 along the length direction thereof.
The outer side wall of the rotary pipe 7 is fixedly connected with a storage net box 9 with a hollow inside, one side of the storage net box 9 opposite to the rotary direction of the rotary pipe 7 is provided with a feed inlet 901 and is hinged with a baffle 10.
Referring to fig. 2 and 6, in the process of backflushing the filtering holes 201 by the backflushing holes 202, rainwater flows into the rotary pipe 7 through the water leakage holes 701, impacts the spiral impeller 8, and the spiral impeller 8 is stressed to drive the storage net cage 9 to rotate through the rotary pipe 7.
When the storage net cage 9 rotates, the baffle plate 10 rotates under the reaction force, so that the feed inlet 901 is opened, and large-area garbage in rainwater above the filter plate 2 can be filtered into the storage net cage 9.
When the filtering holes 201 are dredged, the rainwater flowing into the rotary pipe 7 through the water leakage holes 701 is gradually reduced, the rotary pipe 7 is gradually stopped, the reaction force of the rainwater to the baffle 10 disappears, and the baffle 10 is used for sealing the feed inlet 901 again, so that the large-area garbage is restrained in the storage net cage 9.
Through above-mentioned recoil hole 202 and the cooperation of accomodating box with a net 9, accomodate the large tracts of land rubbish that blocks up filtration pore 201 in accomodating box with a net 9, and then realize the constraint to large tracts of land rubbish, reduced the repeated many times possibility of blocking up filtration pore 201 of large tracts of land rubbish, be favorable to improving the emission effect to urban road surface rainwater.
Referring to fig. 2 and 6, one side of the storage net cage 9 opposite to the feeding hole 901 is fixedly connected with a shovel plate 11, the shovel plate 11 is located below the feeding hole 901 and is abutted against the filter plate 2, the storage net cage 9 can drive the shovel plate 11 to move, and then large-area garbage on the filter plate 2 is shoveled, so that the storage effect of the storage net cage 9 on the large-area garbage is improved.
Referring to fig. 2 and 6, the inlet 901 is located close to the filter plate 2, so that the large-area garbage can be stored in the storage box 9 at the first time after the large-area garbage is reversely flushed out of the filter hole 201 from the reverse flushing hole 202.
Referring to fig. 2 and 6, the rotary tube 7 is slidably arranged on the filter plate 2, and a limiting ring 12 is fixedly arranged on the outer side wall of the rotary tube 7, and the limiting ring 12 is positioned above the filter plate 2. Limiting ring 12 is to changeing pipe 7 and is realized spacingly, and the municipal administration workman can be through changeing pipe 7 and will accomodate box with a net 9 and propose downcomer 1, and then conveniently clear away the large tracts of land rubbish of accomodating in the box with a net 9.
The implementation principle of the municipal rainwater anti-blocking type discharge system provided by the embodiment of the application is as follows:
when the filter holes 201 are blocked, the more rainwater is accumulated above the filter plate 2.
On the one hand, rainwater overflows from the sewer pipe 1 into the overflow water chamber 3, the water level of the rainwater in the overflow water chamber 3 gradually rises, the floating ball 42 is subjected to the action of buoyancy force in the rainwater and the buoyancy force gradually increases, so that the lifting arc plate 41 is driven to gradually move upwards, and when the lifting arc plate 41 ascends, a plurality of water inlets 410 on the lifting arc plate 41 sequentially introduce the rainwater into the corresponding water inlet 203 and the corresponding backflushing hole 202 along the direction from top to bottom.
