Specific embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
It is a kind of can desanding current limliting shutoff type inlet for stom water, as shown in FIG. 1 to 3, including water inlet grate 1, water inlet grate 1 around have
The gradient, rainwater is entered in well along the gradient by grate 1 of intaking, and rainwater passes sequentially through the string bag 4 and hand basket 5, hand basket 5 include pull bar 6,
Folding rod 7, trip lever 16, base plate 8 and side panel, early-stage rainwater through the blowdown of intercepting sewer 3 to outside sewage network, dirt of damming
The front end of water pipe 3 sets current limiter 9, and current limiter 9 includes chamber 10, sewage aperture 13, ball float 11 and flashboard in chamber 10
12, sewage aperture 13 is connected with intercepting sewer 3, and linkage unit is connected between ball float 11 and flashboard 12, and ball float 11 rises
Or drive flashboard 12 down or up when declining.After water level reaches the ttom of pipe of rain pipe 2, stormwater overflow is entered to rain pipe 2
River course.
The string bag 4 in the present embodiment is arranged on the top of inlet for stom water main body, can effectively intercept polybag in rainwater,
The isometric larger impurity of branch.
Hand basket 5 in the present embodiment is used for intercepting the impurity such as the gravel in rainwater, including pull bar 6, folding rod 7, trip lever
16 support frames 17 and base plate 8.Pull bar 6 and base plate 8 are connected, and trip lever 16 and folding rod 7 are directly connected to, and trip lever 16 is located at pull bar
6 inside.Hand basket 5 is placed on support frame 17, and the side panel of base plate 8 and hand basket surrounding has all been covered with circular hole, and rainwater passes through
During hand basket 5, water can pass freely through circular hole, and gravel is retained on base plate 8.The side panel bottom of hand basket can cross water, when base plate 8
When being plugged, water freely can cross water from hand basket side panel bottom.When needing to empty hand basket 5, lifting device and pull bar 6 are connected
Connect, hand basket 5 is pulled out, untie the trip lever 16 in pull bar 6, base plate 8 folds opening, gravel meeting under the drive of folding rod 7
Fallen from bottom.After emptying and be over Deng hand basket 5, then on the support frame 17 put back in inlet for stom water, into next round work.
The surrounding of hand basket 5 does buckle supporting construction, convenient that hand basket is proposed from well.
Hand basket 5 is made of fiberglass or HDPE material.
The appearance and size of hand basket 5 can be 1m*1m*0.5m, and effective volume is 0.5m3.
Current limiter 9 is unpowered current limiter in the present embodiment, without external power during operation, saves electric energy.Sewage aperture
13 bore is identical with the internal diameter of intercepting sewer 3.Chamber 10 is designed to cover structure of diving under water, the bottom of chamber 10 be it is open,
There is certain air all the time in chamber 10, during operation, the air in chamber 10 is caught in and will not flow out, due to the work of air pocket
With, pressure in chamber 10 is consistently lower than external water level more than outside pressure, the water level in chamber 10, by outside liquid level and
Air in chamber 10 jointly controls the height of ball float 11, so that the open degree of flashboard 12 is controlled, by liquid level and sewage aperture
13 areas realize out the constant control of stream.Linkage unit includes swing rod 14, the mobile jib 15 through swing rod 14, the two ends point of swing rod 14
It is not connected with ball float 11, flashboard 12, the two ends of mobile jib 15 are separately fixed on the inwall of chamber 10, when ball float 11 rises, pendulum
One end of bar 14 declines so as to drive flashboard 12 to decline；When ball float 11 declines, one end of swing rod 14 rises so as to drive flashboard 12
Rise.Because ball float 11, flashboard 12 and linkage unit are arranged in chamber 10, it is to avoid because external water level exceedes ball float 11
The risk of the current limliting failure that maximum movement highly causes, in addition, in well during SEA LEVEL VARIATION, the ball float 11 in chamber 10 need not
Mobile identical distance, because closed compressed air gives ball float 11 downward pressure in chamber 10, this allows for limit
Stream device 9 can be adapted to smaller well body, applied widely.
When current limiter 9 needs to significantly alter flow, it is not necessary to change whole equipment, it is only necessary to change and be responsible for current limliting
Flashboard 12, it is convenient and swift, it is time saving and energy saving, save cost.
A diameter of DN100 of current limiter 9, current limliting flow is 2-10l/s.
Current limiter 9 is made of fiberglass or HDPE material.
The use pattern of current limiter 9 mainly include small-sized rainfall during and heavy rain during two kinds of pattern：
(1) under pattern during small-sized rainfall, flashboard 12 is in rest position, and early-stage rainwater enters well by grate 1 of intaking
Interior, sewage aperture 13 is completely unimpeded, and the ball float 11 in chamber 10 is similarly in the rest position of the top of sewage aperture 13.
(2) during heavy rains under pattern, early-stage rainwater is entered in well by grate 1 of intaking, and Well Water Level rises, in chamber 10
Water level can also rise therewith, and water level once reaches the position of the inner float ball 11 of chamber 10, and controlling mechanism starts immediately, ball float 11 it is upper
Rising causes flashboard 12 to decline, therefore reduces the cross-sectional area in sewage aperture 13, the size in limitation sewage aperture 13, so as to limit
Flow processed.
The above-mentioned description to embodiment is to be understood that and use practicality for ease of those skilled in the art
It is new.Person skilled in the art obviously can easily make various modifications to these embodiments, and illustrating herein
General Principle be applied in other embodiment without by performing creative labour.Therefore, the utility model is not limited to above-mentioned
Embodiment, those skilled in the art according to announcement of the present utility model, do not depart from improvement that the utility model category made and
Modification all should be within protection domain of the present utility model.
