The utility model relates to a Chinese patent of fixed-inclination type tipping bucket rainfall sensor for adjusting the height of a tipping bucket counterweight body, which has the following patent application numbers: 202110890249.4, patent publication No.: CN 113484938A. Disclosed is a dump bucket rainfall sensor, comprising: the device comprises a rain bearing port assembly 1, an outer barrel 2, a base 3, a water injection funnel 4, a tipping bucket support 5, a metering tipping bucket assembly 6, a left tipping bucket inclination angle support assembly 7, a right tipping bucket inclination angle support assembly 8, a reed pipe 9, a horizontal bubble 10, a horizontal support plate 11 and a support plate horizontal adjusting device 12; wherein, the measurement tipping bucket assembly 6 comprises: a tipping bucket shaft 6-1, a middle clapboard 6-2, a left bucket chamber 6-3, a right bucket chamber 6-4 and a permanent magnet 6-5.
The tipping bucket type rainfall sensor is the most extensive rainfall measuring instrument used in various countries in the world at present, and the known tipping bucket type rainfall sensor has the outstanding advantages of simple structure, long service life, low price and no power consumption, can be used for remote measurement, and is widely used in various fields of hydrology, water conservancy, agriculture, meteorology, flood control, disaster reduction, transportation and the like.
The working principle of the known tipping bucket type rainfall sensor is as follows: a tipping bucket type mechanical bistable weighing mechanism based on a balance weighing principle.
The known water injection method is a water injection method at the root of the hopper chamber, and water columns are injected into the root of the hopper chamber along the axle center of the tipping bucket through the axial lead of a water injection funnel. The water injection method is adopted in the known tipping bucket type rainfall sensor without exception.
The mechanical bistable structure is a structural form used by a common tipping bucket rainfall sensor, and the mechanical bistable structure comprises the following components: the error is Δ Vx.
The bistable tipping bucket type rainfall sensor is installed by utilizing the left and right inclination of a tipping bucket component, the swing angle theta between the central line of a water injection column and the central line of a middle partition plate of the tipping bucket is = 11-22 degrees, and the weight of the sensor in the vertical direction is as follows: wLeft side of、WRight sideThe weight is used for measuring the weight of water bearing in the tipping buckets on the right side and the left side of the opposite side. When the water inlet amount of the water storage bucket reaches the preset weight W, the tipping bucket overturns and pours water until the other empty tipping bucket enters a water storage state, and the tipping bucket continuously enters water in a section of area with a time period t when the tipping bucket starts to overturn until rainwater is injected into the other bucket chamber, so that the error Vx without being metered occurs.
∆Vx=V0-VP...................（1）
In the formula:
the absolute error amount generated by the bucket in each turnover is called as the device difference, and the unit is ml;
V0the unit is ml which is the theoretical value of the tipping bucket in a certain corresponding sensing quantity;
VPmeasured drainage quantity value, unit is ml;
the current Vx is the inevitable metering error of the tipping bucket type rainfall sensor, and the magnitude is related to the injection intensity Q and the water injection switching time t of the bucket chamber, and the formula is as follows:
∆Vx=Q·∆t...................（2）
in the formula: the time to switch the water injection is the time to switch the two chambers. The size of the Δ t is related to the size of the tipping bucket water overturning transition angle and the size of the self mass of the tipping bucket body.
The motion equation is as follows:
m-type upper hopper chamber rainwater turnover kinetic moment
I-moment of inertia of the tipping bucket component;
omega-tipping bucket component turnover angular velocity;
t-switching time of water injection of the tipping bucket component.
Relative error E of tipping bucket type rain intensity sensor in national standardbThe calculation formula of (2) is as follows:
in the formula:
E bskip bucket metering error (relative error);
The measurement accuracy grade of the tipping bucket rainfall sensor in China is shown in the following table:
TABLE 1 sensor accuracy rating
| Grade of accuracy | Rain intensity range | Skip bucket metering error Eb |
| Ⅰ | 0.01mm/min～4.0 mm/min | ≤±2% |
| Ⅱ | 0.01mm/min～4.0 mm/min | ≤±3% |
| Ⅲ | 0.01mm/min～4.0 mm/min | ≤±4% |
The known tipping bucket rainfall sensor has four resolutions, namely 1mm, 0.5mm, 0.2mm and 0.1 mm.
Wherein the optimized value of the swing amplitude angle theta of the tipping bucket rainfall sensor with the resolution of 1mm is 22 degrees.
The optimized value of the swing amplitude angle theta of the 0.5mm resolution tipping bucket rainfall sensor is 15-16 degrees.
The optimized value of the swing amplitude angle theta of the 0.2mm force-distinguishing tipping bucket rainfall sensor is 11 degrees.
The 0.1mm resolution tipping bucket rainfall sensor is of a multilayer tipping bucket type structure.
The measuring error of the tipping bucket rainfall sensor with the resolution of 1mm can reach the I-grade range of the national standard of less than or equal to +/-2 percent, but the tipping bucket is abandoned because the sensor is not suitable for measuring the rainfall day and the intercepting amount of the tipping bucket is too large.
Wherein the 0.1mm resolution single-layer tipping bucket rainfall sensor has the error of more than or equal to plus or minus 8 percent in the rainfall intensity range of 0.01mm/min to 4.0 mm/min due to too large relative error, and is abandoned by far exceeding the national standard grade III range.
Today single layer skip rain sensors with resolution of only 0.5mm and 0.2mm are in mass production and application.
When the rainfall intensity is changed within the range of 0.01 mm/min-4.0 mm/min, the measurement error of the tipping bucket rainfall sensor with the resolution of 0.5mm can reach the level II of the national standard of less than or equal to +/-3%, the measurement error of the tipping bucket rainfall sensor with the resolution of 0.2mm can reach the level III of the national standard of less than or equal to +/-4%, and the tipping bucket rainfall sensor belongs to a low-grade product with accuracy.
The reliability and the stability of the tipping bucket type rainfall sensor are positively correlated with the swing amplitude angle theta and the quality of the bucket body, and the larger the swing amplitude angle theta is, the larger the reverse moment is, and the higher the stability and the reliability are.
The swing amplitude angle theta of the known 0.5 mm-resolution tipping bucket rainfall sensor is 15-16 degrees, and the swing amplitude angle theta of the known 0.2 mm-resolution tipping bucket rainfall sensor is 11 degrees, which belong to the range with poor reliability and stability. In particular, a small swing angle θ rainfall sensor mounted on a high pole is most problematic in that the sensor shakes when a strong wind is encountered, and false alarm signals without precipitation easily occur.
At present, the world climate changes violently, extreme high-intensity rainfall frequently occurs, the extreme value of the rainfall intensity is far beyond the range of 4.0 mm/min, particularly, the typhoon storm rainfall frequently occurs in coastal areas in the south, the instantaneous rainfall intensity can reach 10 mm/min or even more, the rainfall intensity range of the existing single-layer tipping bucket rainfall sensor is only 0-4 mm/min, and when the rainfall intensity exceeds 4mm/min, the error range rises straightly and the normal work cannot be realized.
In summary, the prior art tipping bucket rainfall sensor has the following disadvantages and shortcomings:
1. the rain intensity range is small, and the normal work can not be realized when the rain intensity range exceeds 4 mm/min.
2. The accuracy is poor, and the accuracy can only reach the II-level or III-level accuracy standard within the 0-4 mm/min rain intensity range.
3. The stability and the reliability are poor, and the rainfall amount false alarm is easy to generate under the strong wind environment.
