's；Automatic turning barrel is the moving component of the system, is formed by turning over bucket 1, support 2, limit rope 3, and it is water storage container to turn over bucket 1,
It is installed on support 2, at middle part, upper position is provided with eccentric shaft, and bucket bottom is furnished with weight 6, and the weight 6 is strip iron block, if
It is placed in and turns over a barrel bottom circular diameter position, through whole bucket bottom, its direction is vertical with eccentric shaft axis, and weight records close to switch
Lay particular stress on the side of device, it is ensured that empty barrel rolls tiltedly in original state to switch tape deck is provided with.Power is followed during operation
Learn principle voluntarily to overturn, turn back, limit rope 3 can aid in turning over bucket rapid time just；Switch tape deck 4 is the record of the system
Part, it is made up of switch and switching value record instrument, float moves up and down proximity switch action, switching value record instrument during operation
Record on off state and corresponding date, moment simultaneously；Flow integrator is the calculating unit of the system, and recorder can be read and deposit
The data of storage, and by the calculating of certain algorithm, output flow data.
Running, data acquisition situation and the method for calculating flux of system is described in detail below：
During actual use, the horizontal segment of tube fit device 7 insertion fluid line, it is true that the two contact portion smears sealing material
Guarantor spills without fluid, and what the alignment of vertical section notch was installed on lower section turns over the bung of bucket 1, and the two vertical spacing, which should be greater than turning over bucket 1, to be overturn
Required spacing, fluid turn over bucket 1 and start water storage, when inner bucket water position reaches certain altitude, float is in buoyancy from after being fallen notch
Upper limit is displaced downwardly to, switch is opened, and switching value record instrument is recorded, and with the increase of inner bucket water amount, is turned over bucket 1 and is more gradually sloped up to
Overturning, liquid in bucket all spills, turns over bucket and then quickly turned back in the presence of bottom weight 6, and under the auxiliary of limit rope 3
Initial position is rapidly returned back to, while float drops back into lower limit, switch is closed, and recorder is synchronously recorded, at this moment, a motion
End cycle, turn over the water storage activity that bucket starts next round.
Switching value record instrument have recorded open and-shut mode (or perhaps the float of switch as data acquisition device
High and low position) and corresponding date and time, the record data that certain experiment obtains by figure as shown in figure 3, can be found that：Float is opened
Close in being periodically opened and closed, corresponding float periodically moves up and down.By taking certain cycle a~a ' in scheming as an example, a~b periods, switch
By closing out, now turn over bucket and just start water storage, float is gradually floating to upper limit；Overturned assuming that turning over bucket at the c moment, b~c periods,
Switch is opened all the time, turns over the rising of inner bucket water position, and ladle body gradually tilts, and float is always positioned at upper limit；C~a ' periods, float
Sub switch is closed by reaching, and the corresponding bucket that turns over is overturned, turned back, and liquid spills, and float finally drops down onto lower limit.
Obviously, a~c periods correspondingly turn over a barrel water receiving process, and c~a ' periods correspondingly turn over a barrel switching process, and through measurement, it is every to turn over bucket
The secondary liquid quality poured out is certain value, and title turns over water, uses mfRepresent, then the water that a~c period current flow down is to turn over
Bucket turns over water, therefore a~c periods are referred to as Tf, must be turned over bucket by testing and turned back time-consuming 3~4s, when this duration corresponds to c~a '
Section, claim Tl。
But there are two kinds of special circumstances should be noted：
First, the first cycle of bucket operating is turned over, when being not used, float is always positioned at lower limit, and recorder does not record this
Signal, therefore first cycle duration can not obtain complete documentation, the process should be cast out during data processing；Second, as shown in figure 3,
Float the cycle junction quick situation about stirring up and down occurs, this is due to turn over bucket to rock there occurs front and rear when turning back,
Can not immediate stability get off, the duration that now float stirs should also be included in TlIn.
Therefore, the instantaneous delivery G and integrated flux m of partly-filled pipe-flowTCalculation formula is as follows：
In above formula,
T --- cycle duration, s；
Tf--- the water receiving stage takes, s；
Tl--- the upset stage takes, s；
G --- water flow, m3/h；
mf--- turn over water, m3；
mT--- the water under n-th of periodic stream, m3。
In summary, the basic process of non-full pipe intermittent current instantaneous delivery measurement is as follows：
(1) selection of pipeline section is measured：There are enough installing spaces down stream outflow port, pipeline lower section；
(2) measuring system installation dimension determines：Pipe under test basic size, pipeline and surrounding environment barrier need to be obtained
Spacing, and determine that the installation dimension of system (has been carried out in detail in embodiment for specific scene according to site specific
Describe in detail bright), it is ensured that turn over bucket and be not blocked in switching process；
(3) measuring system is installed, is fixed, can barrel is turned in observation continuously run under fluid impact, flow accumulation
Can instrument normally export fluid flow；
(4) gathered data and calculating：Fluid flows into automatic turning barrel during detection, and switch tape deck is read automatically
Data, flow integrator calculates and output flow data.
Embodiment 1：
The system is applied to the measurement of certain university dormitory building sanitary sewage flow, and the construction drainage pipeline is dirty positioned at one
In water inspection shaft, well bore internal diameter 980mm, drainage pipeline internal diameter 280mm, pipeline away from well head 1550mm, the water surface away from well head 3500mm,
For field condition as shown in figure 4, drainage pipeline material is PVC bellowss, stretching borehole wall length is shorter, is installed on if will directly turn over bucket
Below pipeline, turning in barrel switching process to be rebuffed, therefore monitoring field simply need to be transformed：
Present case determines the material of tube fit device and specific size for the scene, because sanitary sewage has corruption
Corrosion, the device are made of galvanized steel, and horizontal segment pipe external diameter is slightly less than draining bore, including inserting paragraph and section of stretching out,
Section of stretching out is approximately equal to well bore radius, it is ensured that drainage pipeline is extended into the center of bilge well 8；Vertical section guiding gutter cross section chi
Very little foundation is turned over barrel bung size and determined, it is ensured that notch edges are no more than bucket edge, guiding gutter vertical direction chi under initial mounting state
It is very little to have references to drainpipe design discharge and design degree of filling, under estimating that sewage maximum horizontal flow velocity is determined in its drop process
Relation between drop height degree and forward travel distance, before drawn size of the guiding gutter in current direction of advance, it is anti-according to the size
Sewage height of drop is pushed away, then the size of guiding gutter vertical direction should be greater than the height, and increase a small amount of surplus.During actual use,
One end of tube fit device is stretched into drainage pipeline and fixed, and turns over barrel and is installed on below guiding gutter, through site observation, sewage
Bucket is turned in impact guiding gutter vertical baffle pasting board inflow lower section, and water conservancy diversion, rollover effect are good.Because the field pipes are deeper, dress
It is longer to put mounting bracket, to avoid support front and rear shaking amplitude when turning over bucket upset excessive, spy installs in well above extension tube
Crossbeam 9 carries out spacing.
After installing, measurement apparatus can the continuous running under sewage flow action, measure sanitary sewage flow one day such as
Shown in Fig. 5.It can be speculated by figure：When the dormitory building students concentrate on the morning 9, remaining period is relatively scattered with water, but during evening 19
~0 hourly water consumption is bigger, and almost nobody uses water when early 5, and the above tallies with the actual situation, therefore the present apparatus measures sanitary sewage
Data on flows is credible.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
