The precipitation enters the water collecting funnel from the rain bearing port and then enters the water storage hopper of the tipping bucket through the water collecting funnel, and when the water body of the water storage hopper changes, the total overturning moment M is generatedFThe total reverse torque M is instantaneously greater than the total reverse torque M generated by the factors such as the self weight of the bucket body of the tipping bucketNThe rainwater on the other side is converted into a water storage bucket to play a role in water storage, and the rainwater is measured in a reciprocating mode.

The tipping bucket type rainfall sensor is a fixed shaft type bistable mechanical device based on a moment dynamic balance principle, and measures precipitation in a mode of measuring tipping bucket overturning times.
The moment dynamic balance principle equation is as follows:
∑MS=Md+MP…………………………………(1)
in the formula: mdThe counter torque of the weight of the bucket body (comprising the bucket chamber shell, the middle partition plate, the permanent magnet and the bucket shaft) is gram-centimeter (g-cm). Md=Wd×Ld，WdIs the weight of the bucket body and has the unit of gram (g), LdThe length of the force arm of the bucket body is in centimeters (cm);
MP-counter torque of the counterweight, in units: gram-cm (g-cm). MP=WP×LP，WPIs the weight of the balance weight, and the unit is gram (g), LPThe length of the force arm of the counterweight body is in centimeters (cm);
(1) in the formula: mSThe dynamic moment generated by the weight of the water body in the water storage hopper changes along with the change of the total water storage amount and the outward movement amount of the center of gravity of the water body, and the unit is as follows: gram-cm (g-cm). MS=WS×LS，WSIs the weight of water body and has the unit of gram (g) and LSIs the length of the force arm of the water body and has the unit of centimeter (cm).
The known tipping bucket type rainfall sensor is realized by changing the size of a deflection angle phi of a partition plate in the tipping bucket by adjusting the height of an inclination angle support column in an inclination angle component, wherein the inclination angle adjusting component comprises a stud, the inclination angle support column and a locking screw, and the inclination angle adjusting component is symmetrically arranged on a horizontal support plate at the bottom of the tipping bucket or symmetrically arranged on a vertical support through a fixing screw.
The tipping bucket type rainfall sensor needs to be subjected to accuracy adjustment no matter when the tipping bucket type rainfall sensor is subjected to factory debugging or field use calibrationThe method comprises the following steps: according to the requirements of the national standard GB/T21978.2-2014 tipping bucket type rainfall sensor, the detection is carried out under three specified rainfall intensity conditions of large, medium and small, and the rainfall amount is specified to be 10mm each time (namely, the rainfall amount is 314.16ml for a rain bearing port with the inner diameter of phi 200). The detection is carried out at the height h set by the inclination angle supportxThe process is carried out as follows. The debugging method comprises the following steps: the left inclination angle strut is lifted, and the water turning amount of the right bucket is reduced; the left inclination angle strut is lowered, and the water turning amount of the right bucket is increased. Similarly, the right inclination angle pillar is raised, and the water turning amount of the left bucket is reduced; the right dip angle strut is lowered, and the water turning amount of the left bucket is increased. People who are not familiar with the above rule are easy to operate by mistake.
After the standard steps are completed, if the accuracy is still ultra-poor, the method and the steps must be repeated, and the rainstorm intensity is tested until the rainstorm intensity is qualified, so that the method is very tedious and time-consuming.
The biggest defect of adopting the method for adjusting the height of the inclination angle strut to adjust the overturning water quantity of the tipping bucket is as follows: the accuracy of the adjustment step is extremely coarse and the adjustment step is determined by the existing low-inclination construction of the tipping bucket rainfall sensor.
The measuring accuracy and stability of the known rainfall sensor directly correspond to the size of the inclination angle of the measuring tipping bucket, and the accuracy is high when the inclination angle is small, but the stability and the repeatability are poor; the accuracy is poor when the inclination angle is large, but the stability and the repeatability are good. In order to give consideration to the accuracy and the repeatability, the current situation of the installation inclination angle of the tipping bucket type rainfall sensor is recognized as follows:
the inclination angle phi of the tipping bucket of the 0.5mm resolution rainfall sensor is optimized to be in the range of 15 +/-2 degrees;
the tipping bucket inclination angle phi of the 0.2mm resolution rainfall sensor JD-02 is optimized to be in the range of 12 +/-2 degrees.
The tipping bucket rainfall sensor with the small inclination angle structure necessarily has the result of large overturning quantity adjusting step pitch, and fig. 4 is a structural diagram of a metering tipping bucket assembly in the prior art.

The known techniques are characterized in that: when the height value of the tipping bucket inclination angle support is increased by delta h, the delta M of the tipping bucket body is reduced at the same timedAnd a counterweight body Delta MpTwo moments and simultaneously increase the overturning moment Delta M of the water bodysThe three variable moments are added, so that the adjustment step is particularly coarse.
In addition, Δ M is adjusted onlypIn the known technology, when the height Δ h of the tipping bucket inclination angle strut is adjusted, because the inclination angle phi corresponding to the inclination angle Δ h is an acute angle of 12-15 degrees, the length variability of the corresponding force arm is large and the generated moment variability is also large when the height of the inclination angle screw changes Δ h according to the trigonometric function rule, and the result also enables the adjusting step pitch to be thicker.
Experiments prove that the rainfall sensor with 0.5mm resolution has the h0When the water volume is increased/decreased by 1mm, the water volume of the tipping bucket is changed by +/-5-10 percent. The results also demonstrate the obvious disadvantage of the known technique of extremely large step sizes.
The known mode for adjusting the overturning quantity of the tipping bucket has the following defects and shortcomings: the height of the left and right inclination angle adjusting screws needs to be symmetrically and synchronously adjusted every time the overturning amount of the tipping bucket is adjusted, which is difficult;
the equipment of the prior art has complex structure and high manufacturing cost.
The above disadvantages and shortcomings are inherent in the construction of the prior art and cannot be overcome.
Disclosure of Invention
In order to overcome the defects and shortcomings in the prior art, the invention provides the fixed-inclination-angle type tipping bucket rainfall sensor which has a simpler structure, can finely, accurately and conveniently change the water overturning amount of the left and right bucket chambers and can adjust the height of the tipping bucket counterweight body.
For the above purpose, the object of the present invention is achieved by: a fixed-tipping-bucket rainfall sensor for adjusting the height of a tipping-bucket counterweight body comprises a rain bearing port assembly, a tipping-bucket bracket, a metering tipping-bucket assembly, a tipping-bucket shaft support, a leveling device, a left tipping-bucket inclination strut assembly, a right tipping-bucket inclination strut assembly, a reed pipe, a water injection funnel, a base and an outer barrel; wherein, measurement tipping bucket subassembly include: the tipping bucket shaft, the middle partition plate, the left tipping bucket, the right tipping bucket and the permanent magnet;
the method is characterized in that: the measurement tipping bucket subassembly still including the counter weight body subassembly, the counter weight body subassembly be adjustable high formula counter weight body subassembly, adjustable high formula counter weight body subassembly include: the screw rod support, the screw rod, the counterweight threaded sleeve and the locking nut; the screw rod support is positioned on the same vertical surface on one side of the middle partition plate of the tipping bucket, the screw rod is coaxially arranged on the screw rod support, and the counterweight threaded sleeve and the locking nut are coaxially arranged on the screw rod;
the left tipping bucket inclination angle strut assembly and the right tipping bucket inclination angle strut assembly are fixed height struts, and the height h of the struts, the tipping bucket middle partition plate deflection angle phi and the tipping bucket standard capacity value V are fixed height struts0And (4) adapting.
The tipping bucket type rainfall sensor has the beneficial effects that due to the adoption of the scheme, the advantages of simple structure, high reliability, low manufacturing cost, no power consumption in working and the like of the known tipping bucket type rainfall sensor can be reserved.
The skip bucket sensing quantity adjusting method of the scheme of the invention is characterized in that the height of a screw rod of the lifting counterweight body component on a screw rod support is adjusted, or the height of a counterweight threaded sleeve on the screw rod support is adjusted, and the synchronous adjustment of left and right bucket sensing quantities can be completed by locking a nut. The screw rod is adjusted upwards or the balance weight threaded sleeve is adjusted and locked, so that the sensing quantities of the two water storage hoppers are increased synchronously; and the screw rod is adjusted downwards or the balance weight screw sleeve is adjusted and locked, so that the sensing quantities of the two water storage hoppers are reduced synchronously.
Because the proposal of the invention only adjusts the moment variable Delta M of the counterweight bodypWithout changing the dynamic moment DeltaM of the bucket body and the water bodydAnd Δ MsThese two parameters, and therefore the adjustment step, are finer.
In addition, when the height of the balance weight body on the screw support is adjusted, the balance weight body is operated on the bevel edge of the acute angle of the triangle (12-15 degrees), the corresponding moment arm variability is finer when the height of +/-1 mm is adjusted, the length variability of the moment arm is smaller, and therefore the step pitch is finer to adjust. This can be proven from the corresponding relationship rule of the corner of the trigonometric function.
Experiments prove that the tipping bucket sensitivity variability of the scheme of the invention is 0.5-1% when the height of the tipping bucket is adjusted by 1 mm.
The advantages are that: in conclusion, the invention greatly simplifies the structure of the instrument, reduces the manufacturing cost, and can accurately, finely and conveniently change the water turnover quantity of the left bucket chamber and the right bucket chamber. Meanwhile, the assembly and factory debugging efficiency is obviously improved, the accuracy and calibration efficiency of on-site installation of the instrument is improved, and the use accuracy of the instrument is improved.
