Description

TECHNICAL FIELD

[0001] The utility model relates to a tipping bucket rain sensor technical field, especially an automatic leveling rain receiving port assembly of tipping bucket rain sensor. BACKGROUND

[0002] Tipping bucket rain sensor is the most widely used precipitation measuring instrument in the world, and the known tipping bucket rain sensor has the advantages of simple structure, long service life, low price, no power consumption and remote measurement.

[0003] Rain sensors are widely used in hydrology, water conservancy, agriculture, meteorology, flood control and disaster reduction, transportation and other fields, and are used for measuring precipitation, precipitation intensity and precipitation time data. Its core function is to convert rainfall into digital information that can be recorded and transmitted, providing an important basis for flood control, water supply scheduling, reservoir management and the like.

[0004] Traditional rain receiving ports are designed with an open funnel (usually 200mm in diameter), with an area of about 31416 square millimeters. Every 0.1mm of rainfall is equivalent to 3.14g of rainwater. The tipping bucket rain gauge uses the principle of torque dynamic balance, which means that the water storage bucket has a fixed amount of water storage at the factory. However, in actual use, the rain receiving port is often inclined, causing the area of the rain receiving port to change. With the same rainfall intensity, the inclined rain receiving port has a smaller rain receiving area, resulting in a decrease in the amount of rain received, increasing the measurement error and reducing the accuracy of the rain sensor.

[0005] The torque dynamic balance principle equation is:

[0006] MN=MK…………………………………(1)

[0007] (1) In the formula: MK - the inverse torque of the weight of the bucket (including the bucket shell, the middle partition, the permanent magnet and the tipping bucket shaft), unit: gram-centimeter (g·cm). MK=FK×LK, FK is the weight of the bucket, unit: gram (g), and LK is the length of the force arm of the bucket, unit: centimeter (cm);

[0008] MF=MS…………………………………(2)

[0009] (2) In the formula: MS - the dynamic torque generated by the weight of the water in the water storage bucket, which changes with the total amount of water storage and the amount of water body weight moving outward, unit: gram-centimeter (g·cm). MS=FS×LS, FS is the weight of the water, unit: gram (g), and LS is the length of the force arm of the water, unit: centimeter (cm);

[0010] In actual use, the tipping bucket rain sensor is often installed on a vertical pole, and due to the settlement of the foundation or the deformation of the vertical pole, the rain receiving opening of the tipping bucket rain sensor is in an inclined state without automatic horizontal detection, and the maintenance personnel cannot timely find and adjust the tipping bucket rain sensor to the horizontal state, so that the water receiving area of the rain receiving opening is affected, and the accuracy of the rain sensor is affected.

[0011] The rain receiving opening of the tipping bucket rain sensor installed on the vertical pole is often difficult to be adjusted to be flat, because the vertical pole is high, when a person adjusts the rain sensor by means of a ladder, the ladder pushes the vertical pole to be inclined, even if the person adjusts the rain receiving opening of the rain sensor to be flat at this moment, after the person gets down, the inclination angle of the vertical pole changes, the rain receiving opening of the rain sensor is in an inclined state, and the accuracy of the rain sensor is greatly affected, so that the real rainfall condition is difficult to be reflected.

[0012] In summary, the tipping bucket rain sensor has the following disadvantages and deficiencies:

[0013] 1. Due to the settlement of the foundation or the deformation of the vertical pole, the whole rain sensor is inclined without automatic horizontal detection, the water receiving area of the rain receiving opening is changed, and the accuracy of the tipping bucket rain sensor is affected.

[0014] 2. The rain receiving opening of the tipping bucket rain sensor installed on the vertical pole is often difficult to be adjusted to be flat, and the accuracy of the rain sensor is greatly affected.

[0015] 3. In order to ensure the accuracy of the tipping bucket rain sensor, a large amount of manpower and financial resources are often needed for maintenance, especially many rain stations are arranged in mountainous areas, and a project has hundreds or even thousands of rain stations, even if many people maintain at the same time, it is difficult to ensure the accuracy of the tipping bucket rain sensor.
