Guide tank, rectifier stack, downspout strainer, Combined metering weir plate and water stage measurement component；Wherein,
Water inlet, the rectification that setting is connect with the water inlet in the guide tank is arranged in the upper surface of described guide tank
Component；
The downspout strainer is located above the guide tank, covers the water inlet above the guide tank；
The Combined metering weir plate, the upper and lower parts point of the Combined metering weir plate are arranged in the one side of the guide tank
Effluent weir there are two not setting；
The bottom of the guide tank is inclined floor, and the high-end of the inclined floor is arranged described group in the guide tank
The side of total amount weir plate；
The water stage measurement component is located at bottom in the guide tank, can measure water level in the guide tank, be calculated
The weir head of flow.
In above-mentioned measuring device, guide tank is body structure wide at the top and narrow at the bottom, and the height difference of the inclined floor is not less than
40mm, the gradient direction of the inclined floor are opposite with the effluent weir water discharging direction of the Combined metering weir plate.This structure is just
When weep, silt particle sinks to the bottom end of the inclined floor in guide tank, avoids the effluent weir of blocking Combined metering weir plate, and
In mass-flow, the lower part effluent weir of the combined metering weir plate in bottom of the silt particle in guide tank is washed away into discharge, realizes the survey
Measure the auto-flushing of device.
In above-mentioned measuring device, the effluent weir on Combined metering weir plate top is Cipolletti weir, and the effluent weir of lower part is triangular-notch weir,
The area of triangular-notch weir is less than Cipolletti weir (referring to fig. 2), is a kind of up big and down small Combined metering weir plate.By using Combined metering
Weir plate carries out the metering of rainwater flow, solves in the even biggish situation of property of mass flow discrepancy, can obtain enough accuracy and range.
In above-mentioned measuring device, rectifier stack is the group being welded by two vertical cowling panels and four lateral cowling panels
Close frame structure.
In the rectifier stack of above-mentioned measuring device, multiple apertures, each vertical cowling panel are equipped on the vertical cowling panel

Opening diameter on each transverse direction cowling panel is gradually reduced.Preferably, the opening diameter range on vertical cowling panel are as follows: 10mm~
15mm；Opening diameter range on each transverse direction cowling panel are as follows: 15mm~8mm.
In above-mentioned measuring device, water stage measurement component is recorded by sequentially connected pressure sensor, pressure transmitter and data
Transmitter composition is recorded, the pressure sensor is located at the bottom in the guide tank, in the rectifier stack and the combination
It measures between weir plate.
It is recognised that the shape of apparatus of the present invention is not limited by schematic diagram, only shape change is also belonged to of the invention
Protection scope.
The device of the invention is flowed out by determination of pressure sensor water level, the combined metering weir plate metering of rainwater, while
The silt auto-flushing of deposition is discharged when great deal running water, realizes silt auto-flushing, is suitable for roads rain inlet flow
Measurement.
The embodiment of the present invention is specifically described in further detail below.
As shown in Figures 1 to 3, the embodiment of the present invention provides a kind of inlet for stom water flow measurement device of energy auto-flushing, comprising:

Determine component 5 to be made of pressure sensor 5-1, pressure transmitter 5-2, data recording transmitter 5-3.
The working principle of the device are as follows: rainwater is collected after downspout strainer 1 carries out energy dissipating by rectifier stack 3 into guide tank 2,
The effluent weir discharge of combined metering weir plate 4 again；When small rainfall, in 2 bottom of guide tank, rainwater is total by group for sedimentation
The triangular-notch weir 4-1 for measuring the setting of 4 lower part of weir plate goes out to flow；When big rainfall, the triangular-notch weir 4-1 that Combined metering weir plate 4 is divided into is submerged,
Free discharge is flooded in formation, and the Cipolletti weir 4-2 that water level reaches the setting of 4 top of Combined metering weir plate, which is formed out, to flow, through water stage measurement
Component 5 measures water level, obtains weir head, by demarcating the size relation of head and flow, can be obtained inlet for stom water flow；Together
When big rainfall wash away stirring, the silt of 2 bottom precipitation of guide tank is rushed, by the triangular-notch weir of 2 lower part of Combined metering weir plate
4-1 discharge, realizes automatic flushing function.
Water level of the invention is measured by water stage measurement component 5.Rainwater flows into guide tank 2, and different hydraulic pressure make water level
The pressure sensor 5-1 for measuring component 5 issues compliance voltage or current signal, pressure transmitter 5-2 is supplied to, through pressure inverting
Device 5-2 becomes height of water level, sends data record transmitter 5-3 to, can recorde in data record transmitter 5-3, or passes
It is defeated into peripheral hardware.
In above-mentioned apparatus, the effect of downspout strainer is to prevent large-sized branch rotten leaf and solids in rainwater stream from entering flow
Measurement device influences the accuracy of flow measurement.
In above-mentioned apparatus, guide tank 2, rectifier stack 3 and Combined metering weir plate 4 are sheet metal welded connection, and water level is surveyed
Determine component 5 to be fixed in guide tank 2 using engagement thread.
Effective measurement of inlet for stom water flow may be implemented in measuring device of the invention, can also be avoided depositing by auto-flushing
Silt blocks water outlet, and the apparatus structure is uncomplicated, at low cost, easy to use, the flow of energy Accurate Determining inlet for stom water.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Within the technical scope of the present disclosure, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
