Description
Technical Field
[0001] The utility model relates to the technical field of meteorological observation, in particular to a device for eliminating abnormalities in large evaporation data caused by heavy precipitation or strong wind. Background Art
[0002] Evaporation is a natural meteorological phenomenon. Evaporation observation is an important project in every test site of the water conservancy and meteorological departments. Evaporation is an important way to achieve the exchange of water vapor between the ground and the air. In addition to playing an important role in the balance of water expenditure, the study of evaporation is also of great significance in the fields of climate change, water resource utilization, water conservancy irrigation and agricultural evaporation. The evaporation measured by the meteorological observation station refers to the height of the water layer lost due to evaporation in a certain area of water surface within a certain time interval. The observation quality of the meteorological observation station is closely related to the water level height of the evaporation barrel.
[0003] For example, the patent application number is 202121052383.9, which discloses an automatic maintenance device for an evaporator used in a meteorological observation station. It discloses "including a ball valve, wherein a left water pipe and a right water pipe are fixed to the left and right ends of the ball valve respectively. By setting a water valve, a water pump, an ultrasonic sensor, a measuring barrel, a lower water level line, and an upper water level line, the evaporation barrel and the measuring barrel are connected. The water level in the measuring barrel and the evaporation barrel are at the same horizontal height. By measuring the water level in the measuring barrel, the water level in the evaporation barrel can be measured. The ultrasonic sensor senses the water level in the measuring barrel. When the water level is lower than the lower water level line, the ultrasonic sensor triggers the single-chip microcomputer to control the water valve to open, and water starts to be injected into the evaporation barrel. When the external precipitation causes the water level in the evaporation barrel to rise to a certain level, When the digital level in the measuring bucket reaches the upper water level line, the ultrasonic sensor transmits a signal to the single-chip microcomputer to control the water pump to start pumping out the excess water in the evaporation bucket, thereby achieving the function of automatically controlling the evaporator. "Although the above structure can realize the measurement of the evaporation data of the evaporation bucket, in windy weather, the water surface in the evaporation bucket will be greatly affected by the wind, which will cause a large fluctuation, affecting the measurement of the data; and in precipitation weather, precipitation will also directly enter the evaporation bucket, and the high-speed falling rainwater entering the evaporation bucket will cause a large oscillation of the water surface in the evaporation bucket, affecting the measurement of the data. The above technical solution cannot cope with the above problems. It can be seen that some equipment is urgently needed to ensure that the evaporation bucket can be used normally in windy and rainy weather.
[0004] In order to solve the above problems, we provide a device that can use an evaporation barrel in windy and rainy weather to reduce evaporation data errors and eliminate the abnormality of large evaporation data caused by precipitation or strong wind. Utility Model Content

[0011] Furthermore, one end of each group of rollers is connected to a motor, and the motor is fixed on the connecting seat.
[0012] Furthermore, the length of the roller is greater than the length of the evaporation barrel.
[0013] Furthermore, the precipitation buffer net is made of a material that can be wound and stored, and the length of the precipitation buffer net is greater than the length of the evaporation barrel.
[0014] When the utility model is used, in case of strong winds, in order to prevent the wind from blowing the water in the evaporation barrel to a large extent and causing the water surface to shake greatly, thus affecting the measured data; a protective frame that can move up and down can change the wind direction to enter the evaporation barrel, and the protective frame is a strip-shaped or hole-shaped structure, which can change the wind direction entering the evaporation barrel through the protective frame, thereby preventing the water in the evaporation barrel from being greatly shaken by the wind, and preventing the wind entering the evaporation barrel from directly blowing to the water surface, causing the water surface to shake and fluctuate, thus affecting the measurement of data; the specific strip-shaped or hole-shaped structure is set as the prior art without technical restrictions, and the wind direction entering the evaporation barrel from the protective frame can be changed to avoid direct strong wind blowing on the water surface, for example, by taking the hole-shaped structure and setting it obliquely, the wind entering the evaporation barrel can be blown upward or to the side; that is, by controlling the electric cylinders on all sides to move up and down synchronously, the protective frame can be moved up and down as a whole, and the protective frame is higher than the upper surface of the evaporation barrel, which can effectively change the wind direction entering the evaporation barrel, thereby reducing the influence of strong winds on the measured data. In order to prevent precipitation from affecting the accuracy of data measurement when it rains, a foldable precipitation buffer net can be used to solve the above problem: the precipitation buffer net is designed as a mesh leak structure as needed, and rainwater falling on the precipitation buffer net can drip into the evaporation barrel.

[0022] Embodiment 1, as Figure 1 —4, the purpose of the utility model is achieved as follows: a device for eliminating the abnormality of large evaporation data caused by precipitation or strong wind, comprising a base 1, an evaporation barrel 4 is arranged in the middle position of the base 1, and a protective frame 8 is arranged in the base 1 which can move up and down. When the protective frame 8 is raised, the wind direction in the evaporation barrel 4 can be entered, thereby reducing the inaccuracy of the measured data caused by the fluctuation of the water surface caused by the direct blowing on the water surface. The protective frame 8 is located on the outside of the evaporation barrel 4, and a precipitation buffer net 9 is arranged on the top of the protective frame 8. The precipitation buffer net 9 can be unfolded as needed. The unfolded precipitation buffer net 9 can prevent rainwater from falling directly into the evaporation barrel 4 at high speed, causing the water surface in the evaporation barrel to vibrate and affect the measurement of data.
[0023] An observation platform 3 is fixedly arranged outside the evaporation barrel 4 , so that personnel can stand on the observation platform 3 to observe the inside of the evaporation barrel 4 .
[0024] A plurality of electric cylinder grooves are provided inside the protective frame 8, each of which is provided with an electric cylinder 11. The bottom of the electric cylinder 11 is fixed to the bottom of the base 1, and the top output end of the electric cylinder 11 is fixedly connected to the top of the electric cylinder groove.
[0025] The outer side surface of the protective frame 8 is movable up and down with two groups of rotatable rollers 10 on the left and right, one group of rollers 10 is wound with a precipitation buffer net 9, and the front and rear parts of the other group of precipitation buffer nets 9 are fixedly connected to the traction ropes 5 respectively.
