Wherein, the metering tipping bucket assembly 6 comprises: the device comprises a bucket axle 6-1, a middle partition board 6-2, a left bucket 6-3, a right bucket 6-4 and a permanent magnet 6-5; a middle baffle plate 6-2 is arranged between the left tipping bucket 6-3 and the right tipping bucket 6-4, the middle baffle plate 6-2 separates the two tipping buckets into a symmetrical left tipping bucket 6-3 and a symmetrical right tipping bucket 6-4, and a tipping bucket shaft 6-1 is arranged on the bottom surface of the tipping bucket at the lower end of the middle baffle plate 6-2; permanent magnets 6-5 are connected to the side walls of the left tipping bucket 6-3 and the right tipping bucket 6-4.
The left tipping bucket 6-3 and the right tipping bucket 6-4 are mutually a water discharge bucket or a water storage bucket, when one tipping bucket is filled with a certain amount of water, the tipping bucket turns over with the tipping bucket shaft 6-1 as the other axial side, the tipping bucket turns over downwards to be the water discharge bucket, the tipping bucket turns over upwards to be the water storage bucket, and the water bearing mouth of the tipping bucket serving as the water storage bucket is positioned below the water outlet of the water injection funnel 4 in a repeated manner; the permanent magnet 6-5 is arranged on the tipping bucket, the reed pipe 9 is arranged at a corresponding position on the tipping bucket support 5, and in the tipping bucket overturning process, the permanent magnet 6-5 is separated immediately after approaching the reed pipe 9, so that a contact in the reed pipe 9 is closed and opened once, a signal is generated each time of tipping bucket overturning, and a rainfall amount acquisition display instrument and a data processing system display rainfall amount and process data through signal acquisition accumulation.
The precipitation enters the water injection funnel 4 from the rain bearing opening, and then enters the water storage hopper of the tipping bucket through the water injection funnel 4, and when the water storage hopper changes, the total overturning moment M is generated F The total reverse moment M generated by factors such as instantaneous greater than the self weight of the tipping bucket body N When the rain water storage bucket is turned over instantaneously, the received rain water is drained, and the tipping bucket at the other side becomes a water storage bucket and plays a role in water storage, so that the rain water is metered in a reciprocating manner.
The moment dynamic balance principle equation is as follows:
M N =M K. (1)
(1)wherein: m is M K The reverse moment of the weight of the bucket body (comprising the bucket chamber shell, the middle partition plate, the permanent magnet and the tipping bucket shaft) is expressed in grams per centimeter (g per cm). M is M K =F K ×L K ，F K The weight of the hopper body is given in grams (g), L K The physical arm length is the length of the bucket body, and the unit is centimeters (cm);
M F =M S. (2)
(2) Wherein: m is M S The dynamic moment generated by the weight of the water body in the water storage hopper is changed along with the change of the total water storage amount and the external shift of the center of gravity of the water body, and the unit is: gram-cm (g-cm). M is M S =F S ×L S ，F S The unit is gram (g) and L is the weight of the water body S The length of the moment arm of the water body is in centimeters (cm);
in the actual use process, strong wind often damages the theoretical moment dynamic balance, the strong wind enters the sensor from the drainage funnel 13, a moment is applied to the metering tipping bucket assembly 6, so that the metering tipping bucket assembly 6 turns over in advance or turns over in a delayed manner when the rainfall sensor is used for rainfall observation, and the sensor observation data error is larger; when no precipitation exists, strong wind enters the sensor from the drainage funnel 13, blows the metering tipping bucket assembly 6, the permanent magnet 6-5 enters the induction area of the reed pipe 9, and the rainfall sensor misreports data.
Because the rainfall sensor works in the field environment for a long time, insects often enter the sensor, the flexibility of moving parts is affected, and even the blockage of a waterway inside the sensor is caused, so that the reliability and the accuracy of the sensor are affected.
In precipitation observation, the strong wind weather is an important cause for causing the false overturning action of the tipping bucket type rainfall sensor to form an observation error, and meanwhile, the self structure of the tipping bucket type rainfall sensor is damaged to influence the use. The climate in China is complex and various, especially in partial coastal areas, typhoons frequently occur each year, and the precipitation observation is influenced. What is needed is a tipping bucket type rainfall sensor which can be suitable for observing the rainfall under the weather conditions such as storm, typhoon and the like.
To sum up, the tipping bucket type rainfall sensor in the prior art has the following defects:
1. when the strong wind weather works, strong wind enters the sensor from the drainage funnel, and the theoretical moment dynamic balance is destroyed, so that the sensor observation data error is larger or the rainfall sensor misinformation data is caused.
2. The rainfall sensor works in the field environment for a long time, and insects often enter the sensor to influence the flexibility of moving parts and even cause blockage of waterways inside the sensor to influence the reliability and accuracy of the sensor.
