Description

Technical Field

[0001] The utility model relates to an automatic evaporation measuring device, in particular to a negative pressure difference type water surface evaporation measuring dish, belonging to the technical field of evaporation amount measuring tools. Background Art

[0002] Water surface evaporation is the measurement of the evaporation of water in the atmosphere at certain time intervals. Traditional artificial observation equipment uses a small evaporating dish. A 20-centimeter-deep layer of water is poured into the evaporating dish every day. At night, the remaining water is poured into a measuring cup to measure the remaining water depth. The result obtained by subtracting the remaining water depth from 20 centimeters is the evaporation amount for that day, which refers to the evaporation measured in the 20-centimeter-diameter evaporating dish commonly used in my country's meteorological stations.

[0003] According to the patent number CN219368859U, a negative pressure difference water surface evaporation measuring dish is disclosed, including a transparent sealed tubular container with a millimeter scale, an evaporating dish, a connecting water pipe with a water valve switch, an air pressure measuring chamber, and a disc base; the top of the transparent sealed tubular container is provided with a water filling port and a water filling port sealing cover sealing the water filling port, an exhaust port and an exhaust port sealing cover sealing the exhaust port.

[0004] During the implementation of the above scheme, the principle of atmospheric pressure can be used to closely combine the manual observation and automatic observation of water surface evaporation. However, during the implementation of the above scheme, it is difficult to level the evaporation dish. If the evaporation dish is tilted at an angle when placed, the water surface measurement instrument inside it will cause a certain degree of error in the measurement result of the water surface, which will ultimately affect the accuracy of the device in measuring the water surface evaporation. For this reason, we provide a negative pressure difference water surface evaporation measuring dish to solve the above problem. Utility Model Content

[0026] The utility model embodiment provides a negative pressure difference type water surface evaporation measuring dish.

[0027] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a fixed base 1. The evaporating dish 2, fine-tuning screw 10, electric push rod 301, bubble level 6, wires and leveling button 7 involved in this application are all prior arts, and will not be described in detail in this application. Bolt holes are left inside the fixed base 1, which is convenient for measurement personnel to fix the fixed base 1 in a position suitable for water surface measurement through threaded nails to ensure the stability of the evaporating dish 2.

[0028] An evaporating dish 2 is arranged above the fixed base 1 , and a gap of a certain width is left at the connection between the evaporating dish 2 and the fixed base 1 . When the evaporating dish 2 is leveled above the fixed base 1 , the gap can provide space for the leveling operation of the evaporating dish 2 .

[0029] See also Figure 2 and Figure 3 The bottom surface of the evaporating dish 2 is fixedly connected with an upper support column 4, and the top surface of the fixed base 1 is fixedly connected with a lower support sleeve 5. The upper support column 4 is adapted to the lower support sleeve 5, and the upper support column 4 can rotate inside the lower support sleeve 5. The friction between the two is relatively large, which can provide a certain resistance for the leveling of the evaporating dish 2, thereby preventing the evaporating dish 2 from shaking too much during the leveling operation and causing the water inside the evaporating dish 2 to overflow.

[0030] See also Figure 1 and Figure 2 Two groups of bubble levels 6 are fixedly connected to the outer surface of the evaporating dish 2, and two groups of leveling buttons 7 are fixedly installed on the outer surface of the evaporating dish 2. When the bubbles inside the bubble level 6 are located in the middle position, it means that the evaporating dish 2 is in a horizontal state. If the bubbles inside the bubble level 6 are not located in the middle position, the evaporating dish 2 can be leveled by pressing the leveling button 7. The leveling button 7 is electrically connected to the electric push rod 301 through an electric wire, and the lifting and lowering of the electric push rod 301 can be controlled by the leveling button 7.

[0031] A sealing cover 8 is fixedly connected to the outer surface of the evaporating dish 2, and the bottom end of the sealing cover 8 is fixedly connected to the fixed base 1. The sealing cover 8 is made of rubber, which can prevent a large amount of precipitation from entering the fixed base 1 through the gap between the fixed base 1 and the evaporating dish 2, and will not affect the leveling operation of the evaporating dish 2, thereby preventing water from damaging the components inside the fixed base 1 and extending the service life of the components inside the fixed base 1.

[0032] The outer surface of the evaporating dish 2 is fixedly connected with a connecting water pipe 9, and the outer surface of the connecting water pipe 9 is fixedly connected with a fine-adjusting screw 10. The fine-adjusting screw 10 penetrates the evaporating dish 2 and is fixedly connected with the evaporating dish 2. The connecting water pipe 9 is connected to an external transparent sealed tubular container, and can replenish water and air to the evaporating dish 2 according to measurement requirements. The fine-adjusting screw 10 can fine-tune the water level inside the evaporating dish 2 according to set parameters, so that the water level inside the evaporating dish 2 is maintained at a certain height, which is convenient for accurate measurement of evaporation.

[0033] See also Figure 2 , Figure 3 and Figure 4Two sets of leveling mechanisms 3 are arranged inside the fixed base 1. The leveling mechanisms 3 include an electric push rod 301 and a leveling groove 302 provided on the bottom surface of the evaporating dish 2. The fixed end of the electric push rod 301 is fixedly connected to the fixed base 1. The two sets of leveling mechanisms 3 correspond to the two sets of bubble levels 6 and the leveling button 7, and can adjust the different horizontal directions of the evaporating dish 2, so that the evaporating dish 2 can be kept horizontal to the greatest extent during the measurement process, and the evaporating dish 2 can be prevented from tilting at an angle and affecting the accuracy of the water surface evaporation measurement.

[0034] The interior of the leveling groove 302 is slidably connected to a cross slider 303, and the bottom surface of the cross slider 303 is fixedly connected to a leveling connection block 304. The leveling groove 302 and the cross slider 303 are both cross-shaped designs, which can increase the support of the leveling groove 302 on the cross slider 303, so that the cross slider 303 remains stable during the sliding process. The setting of the leveling groove 302 can provide space for the leveling operation of the device, so that the electric push rod 301 can keep the evaporating dish 2 stable when performing the leveling operation on the evaporating dish 2.

[0035] The leveling connecting block 304 is internally rotatably connected with a leveling rotating rod 305, which passes through the telescopic end of the electric push rod 301 and is fixedly connected to the telescopic end of the electric push rod 301. The staff can control the lifting and lowering of the electric push rod 301 through the leveling button 7. The lifting and lowering of the electric push rod 301 can drive the leveling connecting block 304 to move up and down, thereby lifting and lowering one end of the evaporating dish 2, and finally completing the leveling operation of the evaporating dish 2.

[0036] Please refer again Figure 2 and Figure 3 The top surface of the fixed base 1 is fixedly connected with a stabilizing column 306, and the bottom surface of the evaporating dish 2 is fixedly connected with a stabilizing block 307. The stabilizing column 306 and the stabilizing block 307 are hingedly connected through a pin shaft. The arrangement of the stabilizing column 306 and the stabilizing block 307 can provide support for the lifting and leveling operation of the electric push rod 301, so that the evaporating dish 2 can be stable during the leveling process.

[0037] Working principle: when the surveyor wants to level the evaporating dish 2, he first selects the direction for leveling the evaporating dish 2 according to the position of the bubble in the bubble level 6, and then presses the leveling button 7. The leveling button 7 can control the lifting and lowering of the fixed base 1. The lifting and lowering of the fixed base 1 can drive the leveling connection block 304 to move up and down. The movement of the leveling connection block 304 will drive the cross slider 303 to slide inside the leveling groove 302, thereby providing space for the leveling of the evaporating dish 2. The movement of the leveling connection block 304 will also drive one end of the evaporating dish 2 to rise and fall, and the other end of the evaporating dish 2 will remain stable under the connection of the stabilizing column 306 and the stabilizing block 307. When the bubble inside the bubble level 6 is located in the middle, stop pressing the leveling button 7. At this time, the leveling operation in this direction is completed, so as to avoid the evaporating dish 2 from tilting at an angle when measuring the evaporation of the water surface, and prevent external factors from affecting the measurement data.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
