Embodiment
Referring to Fig.1-3, a kind of flow quantity self-adjusting nodal pattern rain perforaled strainer, including support frame 1 and cover board 2, cover board 2 and support frame 1 Upper end offset, the upper end of cover board 2 offers multiple water inlets 3, and the inner wall of support frame 1 is welded with the guiding collected for water flow Device, the bottom of guiding device are welded with hold-up tank 7, and hold-up tank 7 is connected to by drainage tube 8 with guiding device, hold-up tank 7 it is interior Wall slidably connects kickboard 9, and the upper end of kickboard 9 is welded with interior magnetic patch 10, and the two sides outer wall of hold-up tank 7 is welded with one group of connection Spring 11, the every group of one end of connecting spring 11 far from hold-up tank 7 are welded with stripper plate 12, and the upper end of two stripper plates 12 is welded It is connected to outer magnetic patch 13, two symmetrical sides of support frame 1 offer head tank 14, and the inner wall of two head tanks 14 is welded with jointly Pressure pipe 15, for pressure pipe 15 by being connected to hold-up tank 7 multiple communicating pipes 16, the bottom of pressure pipe 15 is equipped with multiple water outlets 17, two symmetrical sides of support frame 1 are equipped with the lifting device for raising cover board 2.
Guiding device includes the guide plate 4 and link block 6 of arc, the both ends of guide plate 4 and the two sides inner wall phase of support frame 1 Welding, the upper end of link block 6 are mutually welded with the bottom of guide plate 4, and the bottom of link block 6 is mutually welded with the upper end of hold-up tank 7, is led Drainage trough 5 is offered to the bottom of plate 4, link block 6 is connected to by drainage trough 5 with guide plate 4, and drainage tube 8 is plugged in link block 6 On side wall;The upper end cambered surface of guide plate 4 can realize effective guiding role to water flow, so that water flow concentration enters link block 6 In, it is drained in hold-up tank 7 convenient for concentrating, and adsorption net is equipped on the upper end inner wall of guide plate 4, to 4 surface of guide plate Water flow is filtered, and the silt carried in water flow and dope are adsorbed, a large amount of silts is avoided to enter further part, It causes to circulate unsmooth, the silt for only needing fixed time cleaning to adsorb can avoid the generation of line clogging.
Lifting device includes mandril 20 and bull stick 22, and the upper end of support frame 1 offers liter slot 18, and the bottom for rising slot 18 opens up There is turn trough 19, turn trough 19 will rise slot 18 and be connected to head tank 14, and the bottom of head tank 14 is rotatably connected to shaft 23 by bearing, The circumferential side wall of shaft 23 is welded with multiple stressed plates 24, and the upper end of shaft 23 is mutually welded with the bottom of bull stick 22, bull stick 22 with The inner wall of turn trough 19 is slidably connected, and the lower end of mandril 20 offers connecting hole 21, and connecting hole 21 is threadedly coupled with bull stick 22, mandril 20 are slidably connected with the inner wall for rising slot 18, and upper end and 2 bottom of cover board of mandril 20 offset;
High pressure water flow in pressure pipe 15 will generate certain impact to stressed plate 24 after entering head tank 14, and then make Obtaining stressed plate 24 drives bull stick 22 to rotate, and bull stick 22 is threadedly coupled with connecting hole 21, and lead angle is greater than working as screw pair Angle of friction is measured, is not in locking phenomenon, the rotation of bull stick 22 can drive the rising of mandril 20, and mandril 20 equally can be at itself Decline under gravity and bull stick 22 is driven to invert the mistake, it can be achieved that the dynamic change between the lifting and water flow pressure of cover board 2 Journey realizes the timely adjusting of self, guarantees the timely discharge of surface flow.
When surface flow flows into urban discharging pipeline through leaf grating for down pipe, the water flow of concentration by by 2 upper end of cover board it is multiple into The mouth of a river 3 enters inside support frame 1, and falls on guide plate 4, enters under the guiding role of guide plate 4 through drainage trough 5 It inside link block 6, then is entered inside hold-up tank 7 by drainage tube 8, and is accumulated upwards by the lower part of hold-up tank 7, and pass through connection Pipe 16 flows in pressure pipe 15, is finally discharged by multiple water outlets 17, flows to subsoil drain.
When encountering the emergency situations such as heavy rain, the water flow that ground is concentrated is larger, with being entered in hold-up tank 7 in the time Water flow is larger, since the displacement of water outlet 17 is limited, so that the water flow entered in pressure pipe 15 can not be discharged in time, most Pressure pipe 15 is full of at last, so that 15 inside water pressure of pressure pipe increases, the water flow that need to only enter in hold-up tank 7 will be in hold-up tank It is accumulated in 7, with the continuous accumulation of water flow, so that kickboard 9 is gradually risen under buoyancy to the top of hold-up tank 7, this shape Under state, the interior magnetic patch 10 of 9 upper end of kickboard and the outer magnetic patch 13 of 12 upper end of stripper plate are close enough, so that interior magnetic patch 10 and outer Mutual attractive force between magnetic patch 13 overcomes the elastic force of connecting spring 11 enough, shrinks and drives crowded so that connecting spring 11 is pressurized Pressing plate 12 is mobile to 7 side of hold-up tank, while stripper plate 12 squeezes communicating pipe 16, so that it is empty to circulate after 16 compression deformation of communicating pipe Between become smaller, the circulating pressure of water flow increases, so that the water flow pressure poured in pressure pipe 15 persistently increases;
When can not water flow be discharged in time in water outlet 17, high pressure water flow will continue into head tank 14 and give stressed plate 24 Enough thrust, so that stressed plate 24 drives shaft 23 to rotate, the further bull stick 22 for driving upper end is rotated, bull stick 22 and even The threaded connection of hole 21 is connect, so the ascending motion of mandril 20 can be achieved in the rotation of bull stick 22, with the rising of mandril 20, so that lid Plate 2 is jacked up upwards, and the gap of cover board 2 and support frame 1 increases, so that outer water flow can be flowed into directly in support frame 1 from gap Portion is no longer only entered inside support frame 1 by water inlet 3, realizes the quick drainage of external water stream, surface flow is avoided to accumulate It causes road obstructed, ensure that the convenience of traffic.
Water flow on the ground is by after quick drainage, when the water flow that water outlet 17 can be timely discharged into, hold-up tank 7 The water that inside is detained reduces, and kickboard 9 is declined by gravity, and distance widens between outer magnetic patch 13 and interior magnetic patch 10, and magnetic force is not It is enough to overcome 11 elastic force of connecting spring, so it is no longer influenced by extruding communicating pipe 16, while the hydraulic pressure in pressure pipe 15 reduces, water flow The impact of stressed plate 24 is reduced, mandril 20 under the effect of gravity, will drive the reversion of bull stick 22 while be contracted to inside liter slot 18, So that cover board 2 is bonded with support frame 1, avoiding cover board 2 from protruding ground and form roadblock influences pedestrian's walking, the rising of cover board 2 and outer The drainage flow of portion's water flow is positively correlated, while the raising of cover board 2 reduces external water flow pressure, influences cover board in turn 2 rising degree, therefore the rising of cover board 2 and external water stream flow are in the process of a dynamic change, cover board 2 can at any time certainly The dynamic height for being adjusted to a balance, realizes the timely drainage of water flow, guarantees the smooth of traffic.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
