Description
Technical Field
The invention relates to the field of rainfall measuring instruments, in particular to a tipping bucket structure for a tipping bucket type rain gauge and the rain gauge.
Background
The tipping bucket type rain gauge is a hydrological and meteorological instrument for measuring the rainfall in nature and converting the rainfall into digital information quantity expressed in the form of switching value to be output so as to meet the requirements of information transmission, processing, recording, display and the like. The working principle of the tipping bucket type rain gauge is as follows: rainwater collected by the rainwater collector falls onto the tipping bucket through the funnel, the tipping bucket can rotate around a horizontal shaft, the shaft is located in the middle of the tipping bucket, the middle of the tipping bucket is divided into two parts which are not communicated through a partition plate, when the rainwater on one side of the partition plate reaches a preset weight, the tipping bucket starts to turn over, one side containing the rainwater descends, and the other side ascends. The permanent magnet steel is arranged on the tipping bucket, the reed pipe on the base can measure the overturning times of the tipping bucket, the rainfall required for one overturning of the tipping bucket is fixed, the specific numerical value of the tipping bucket can be determined through presetting, the rain collecting area of the rain collector is known, the overturning times of the tipping bucket in a certain time are recorded, and the rainfall can be obtained through calculation.
The middle part of the tipping bucket of the existing tipping bucket type rain gauge is provided with a vertical baffle, the tipping bucket is divided into a left working cavity and a right working cavity by the vertical baffle, when the rainfall reaches the specified sensing quantity of the tipping bucket on the left side, the tipping bucket overturns to discharge the rainfall in the tipping bucket on the left side, one-time measurement of the rainfall is completed, and meanwhile, the tipping bucket on the right side starts to work. The time when the left tipping bucket starts to bear rainwater is T1, the time when the tipping bucket is unbalanced and starts to rapidly turn over is T2, the tipping bucket turns to a horizontal position, namely the upper hopper stops water injection to the left tipping bucket, the time when the right tipping bucket starts to inject water simultaneously is T3, the water quantity flowing into the left tipping bucket from the hopper in a period from T1 to T2 is W, and the water quantity flowing down from the hopper in a period from T2 to T3 is delta W. According to the working principle of the tipping bucket type rain gauge, the tipping bucket overturns once in the time period from T1 to T3, the measured rainfall W injected into the tipping bucket on the left side in the time period from T1 to T2 is measured, and the actual rainfall is the total rainfall (W +. DELTA.W) flowing down from the hopper in the time period from T1 to T3. Therefore, in the process from the moment that the tipping bucket on one side of the tipping bucket rain gauge reaches the sensing quantity to the moment that the tipping bucket turns over, a part of precipitation still falls into the tipping bucket reaching the sensing quantity, and the part of water quantity cannot be measured, so that a measurement error is generated, and the larger the precipitation intensity is, the larger the precipitation measurement error is. The water in the hopper will start to fall into the other side of the skip bucket after the skip bucket rotates a larger angle, and before that, the water in the hopper falls into the descending side of the skip bucket, which causes measurement errors.
