Large evaporator capable of realizing dual-mode measurement

Abstract

The invention discloses a large evaporator capable of realizing dual-mode measurement. The large evaporator comprises a bottom frame and a box frame arranged above the bottom frame, wherein two sidesof the front side frame edge of the bottom frame and the two sides of the rear side frame edge of the bottom frame are each provided with a cutter ring protruding upwards; a left transverse force armand a right transverse force arm are separately arranged above the front side frame edge and the rear side frame edge; the lower ends of the transverse force arms are provided with cutter ring groovescorresponding to the cutter rings; and the cutter ring grooves on the lower end surfaces and the cutter rings on the bottom frame are correspondingly arranged. According to the large evaporator, allforce arms are arranged reasonably; the weight pressure on longitudinal force arms can be directly transmitted to a force sensor; weight pressure at the four corners is transmitted to middle force arms through the vertical force arms, the lever effect of the transverse force arms and the cooperation of the cutter rings and the cutter ring grooves; and after the middle force arms and the longitudinal force arms converge, the weight pressure is transmitted to the force sensor, and therefore, weight measurement data of an evaporation box are more accurate.

Description

technical field [0001] The invention relates to an evaporation measurement device, in particular to a double-mode measurement large-scale evaporator. Background technique [0002] In the prior art, the lysimeter of the surface is an important component in the surface water balance, and the research on the lysimeter of the surface is of great significance in meteorology and water conservation; The lysimeter device usually includes a lysimeter or an evaporator. Its main working principle is to weigh or measure the box placed outdoors or under certain conditions. After the water in the water tank evaporates, it will produce weight or Therefore, the lysimeter data can be obtained accordingly; however, the measurement data of the existing device is not accurate enough, so there are interferences from various external conditions during weighing, and the contact between the whole box and the weighing device is uneven, etc. will have a very large impact on the measured data.
