A kind of compensation method for eliminating rain dynamic error:During original state, on struggle against to side tilt, dumper body to
Opposite side tilts, and rainwater first flows into bucket, and upper bucket can keep in sub-fraction rainwater by temporary room, other rainwater are by upper bucket side
The tipping bucket room with the dumper body of its homonymy is flowed into, when the indoor rainwater of tipping bucket runs up to a certain amount of, this stress of dumper body reaches
Overturn after to borderline balance state, shift fork also drives bucket to overturn at this time, the water in upper bucket continue to flow into dumper body another
In tipping bucket room, so as to reduce the loss of rainwater that top phase dumper body is fallen in dumper body switching process.
In the present embodiment, by adjusting the size of upper bucket water outlet, so as to change product of the different rainfall in upper bucket
Water, rain is bigger, and ponding is more, and ponding is more, will generate the gravity of a bigger to push the overturning of tipping bucket, so as to play
Dynamic error caused by one compensation rainfall difference.
Here is mechanical analysis：
Below without particularly indicating, the unit of quality is g, length unit mm；
If rotation axis is O, the quality of tipping bucket is m1, the center of gravity of tipping bucket is G1, enable OG1=r；
The quality of water by tipping bucket quality m1, upper bucket quality m2, upper bucket center of gravity adjusting screw quality m3, be trapped in
The quality of the quality of water influences in bucket, analyzes the influence value of each factor separately below.
Tipping bucket quality m1Influence (force analysis as shown in Fig. 2)：
The arm of force of tipping bucket is G1P=rsin α；
The then torque M of tipping bucket1=m1grsinα；
If the quality of water is mW1, the center of gravity of water is GW, the tipping bucket center of circle is Q,
Enable OQ=R；∠ EOQ=β；
Then HE=Rsin β cos α；EF=Rcos β sin α
Arm of force HF=HE-EF=Rsin β cos α-Rcos β sin α=Rsin (β-α) of water；
The then torque M of waterW1=mW1gRsin(β-α)
For tipping bucket when will stir, tipping bucket is 0 in the support force that block is subject at this time, our this state is referred to as to face
Boundary's equilibrium state.
In borderline balance state, M1=MW1
That is m1Grsin α=mW1gRsin(β-α)
It can obtain：
Upper bucket quality m2Influence (force analysis as shown in figure 3)：
In order to simplify design, AB=OB=d is taken, mechanical analysis is carried out to upper bucket, if the pivot pin of upper bucket is to the pressure of skip groove
Power is F2If upper bucket center of gravity G2It is b apart from shaft A, then the torque that upper bucket gravity generates is M2=m2Gbsin α, wherein m2For comprising
The quality of adjusting screw.
F2It is M to the upper bucket shaft A torques generatedF2A=F2dcos2α
In borderline balance state, two above torque is equal, i.e. m2Gbsin α=F2dcos2α
F2It is to the upper bucket shaft O torques generated
According to explanation above, water quality W2Generating torque to O is：
Mw2=mW2gRsin(β-α)
In borderline balance state, MF2O=MW2
I.e.
It can obtain
Adjusting screw quality m3Influence (force analysis as shown in figure 4)：
It can similarly obtain, adjusting screw m3Influence to water quality is：
Upper bucket ponding quality m4Influence
When struggling against on water flows to, certain water can be first accumulated in upper bucket, if the centroidal distance shaft of these water is a, then accumulated
Water is to the influence value of water quality：
The quality that water often struggles against is the superposition of above four factors,
That is mW=mW1-mW2-mW4
It is known that mW2、mW4All it is that upper bucket converts dynamics to dumper body by pin, shift fork, and sells in fork slot
Stiction is still had, we ignore in present calculating, and if when we design, and allow mW2+mW4Value connect
Nearly 0, then F values are also zero, and the value of stiction is also close to being 0, then stiction can also ignore.
Because water from it is upper bucket flow into tipping bucket when, overturn after having crossed borderline balance state, water continue from it is upper bucket flow to down
The water of bucket is not involved in breaking balance, our these waters for being not engaged in breaking balance are referred to as water loss, and flow is got over
When big, this water loss is also bigger, and water loss is bigger, and it is fewer than total bucket number of light rain to have resulted in the heavy rain number that always struggles against.For this
A problem, we design water flow to lower hopper opening size be an appropriate value, then, when flow is big, result in
Ponding is more, according to formula：mW=mW1-mW2-mW4
We can obtain, and ponding is more, the water m often to struggle againstWFewer, this has also resulted in the increase of total bucket number, institute
Water loss can be compensated by water accumulating volume, so as to allow rain always struggle against number level off to it is equal.Its value being open can pass through
It tests to obtain.
Above-listed preferred embodiment has been further described the purpose of this utility model, technical solution and advantage,
It should be understood that the above is only the preferred embodiment of the utility model only, it is not intended to limit the utility model, it is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this practicality
Within novel protection domain.
