Operation principle：The dell of one and present apparatus same size are set first on bridge pavement, then by the present apparatus
It is placed in dell and fixes, this sample device can carry out the use of next step, when sleety weather, with the stream of rainwater
Dynamic, road surface mountain has accumulated many water, and at this moment water will enter along the first through hole 3 on case lid 2 in babinet 1, in sludge box 4
Top baffle 5 parallel to the ground is installed, the running car on bridge pavement will not be interfered in this way, with a large amount of in rainwater
Silt, the rubbish of bulk can be obstructed by case lid 2 on top, but silt can enter babinet 1 with rainwater, the setting in babinet 1
There is the first orifice plate 9 of sliding, has third through-hole 12, such silt can be by third through-hole 12 and the second through-hole 11 on the first orifice plate 9
It is filtered, rainwater will flow to 1 bottom of babinet along the fourth hole 17 on the second orifice plate 16, then be flowed along drainpipe 24
Go out, this sample device can normally carry out drainage works, with the increase of use time, because 10 top of fixed block is arranged
To be skewed, the silt accumulated in this way can be deposited in 9 both sides of the first orifice plate, when silting is to constant weight, will give the
One orifice plate, 9 gravity makes the first orifice plate 9 move down, and drum sliding slot 26 is provided in the first orifice plate 9, is had in drum sliding slot 26
The drum sliding block 25 of sliding drives hinge bar 14 also can be in the first sleeve 18 downwards as the first orifice plate 9 moves down in this way
Mobile, because the first sleeve 1 and second sleeve 21 are hinged, and connecting rod 19 stretches into T-type sliding block 20 and the second sliding block 27 is solid
Fixed connection, is provided with cavity 30 in T-type sliding block 20, because of moving downward with hinge bar 14, under the action of lever principle,
Second sliding block 27 can slowly squeeze second spring 28, and T-type sliding block 20 can also move down in T-type sliding slot 29, thus can be slow
Slow makes two fixed blocks 10 be moved to both sides, as center-pole 15 drives the first sliding block 22 to move down, at the first spring 23
In confined state, when the first orifice plate 9 drops to V-type mouth pipe 8, silt will be forced into sludge box with fixed block 10
In 4, T-bar 13 is installed at 9 both ends of the first orifice plate, while ensureing that the first orifice plate 9 will not shift, moreover it is possible to play gear
The effect of block prevents fixed block 10 from stretching into V-type mouth pipe 8, and in this way after silt enters sludge box 4, the gravity of the first orifice plate 9 subtracts
It is small, in the first sleeve 18 the first spring 23 will homing, two such fixed block 10 also can be slow under the action of elastic force
Slowly it is restored to original position, the present apparatus can also continue drainage works, be effectively reduced sanitationman and often clear up the present apparatus
The time of waste, only needing regular check, once whether the present apparatus works normally.
Silt can be precipitated slowly on filter screen 6 after entering sludge box 4, and the moisture in silt can slowly be fallen in sludge box
4 bottom ends are provided with the soakaway trench 7 being connected to babinet 1 in sludge box 4, and such moisture will be flowed into along soakaway trench 7 in babinet 1,
It is discharged eventually by drainpipe 24, opens baffle 5 and periodically clear up the silt in sludge box 4, guarantee to be continuing with next time.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe the originals of the present invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
