[0029] This embodiment provides a calibration and environment simulation device for carbon flux observation equipment. Compared with the prior art, the utility model includes a pump room 1, multiple sets of standard gas release units, a heating unit 3, an atomizing spray unit and a control unit. The control unit is electrically connected to the multiple sets of standard gas release units, the heating unit 3 and the atomizing spray unit. 4 Calibration gas unit and CO 2 The standard gas release unit 22 controls the release of carbon flux and can also control CH 4 and CO 2 By controlling the different proportions of the contents, and controlling the opening and closing of the heating unit 3 and the atomizing spray unit separately or in combination, the operation of the carbon flux device under high temperature, high humidity or dry conditions can be simulated. The utility model solves the technical problem that the environmental simulation device in the prior art can only control a single variable factor and cannot simulate a close natural environment.

[0033] The atomizer 45 is disposed on the other end of the spray branch pipe 44 , and the atomizer 45 is communicated with the spray branch pipe 44 .

[0034] There are multiple spray branch pipes 44, and the atomizers 45 are arranged one by one corresponding to the spray branch pipes 44;

[0035] A plurality of spray branches 44 are provided to meet the needs of environments with different rainfall amounts and rainfall amounts in different regions, or to spray the carbon flux observation device 100 in all directions without dead angles, so as to check the operation of the carbon flux observation device 100 in harsh environments.

[0037] Please also read Figure 2 The utility model provides a specific implementation method based on the above implementation method as follows: the angle adjustment component includes a connecting member 51, a slider 52, an electric push rod and a driving rod 53. The connecting member 51 is fixedly connected to the side wall of the pump room 1, and a vertically arranged slide groove 511 is provided on the connecting member 51; the slider 52 is arranged in the slide groove 511, and the slider 52 slides along the length direction of the slide groove 511; the electric push rod is fixed on the connecting member 51, and the movable end of the electric push rod can be extended and retracted in the vertical direction and is fixedly connected to the slider 52; and the driving rod 53 is arranged at an angle with the spray branch pipe 44, and the two ends of the driving rod 53 are respectively hinged to the slider 52 and the spray branch pipe 44, and the hinged axes are all arranged horizontally.

[0039] For further information, please also refer to Figure 1 The pump room 1 is provided with a first exhaust hole 11, a second exhaust hole 12 and an air distribution unit 23, CH 4 The standard gas release unit 21 includes CH 4 Gas cylinder 211 and first exhaust pipe 213. 4 A first valve 212 is provided on the body of the gas cylinder 211 , and the first valve 212 is electrically connected to the gas distribution unit 23 ; one end of the first exhaust pipe 213 is connected to the first exhaust hole 11 , and the other end of the first exhaust hole 11 is connected to the CH4 gas cylinder 211 .

[0040] Please also read Figure 1 , CO 2 The calibration gas release unit 22 includes CO 2 Gas cylinder 221 and second exhaust pipe 223. CO 2 A second valve 222 is provided on the body of the gas cylinder 221 , and the second valve 222 is electrically connected to the gas distribution unit 23 ; one end of the second exhaust pipe 223 is connected to the second exhaust hole 12 , and the other end of the second exhaust hole 12 is connected to the CH4 gas cylinder 211 .

[0042] In some embodiments, the hose portion 46 is a bellows. The structure of the bellows makes it easier for the spray branch pipe 44, which is equivalent to the spray main pipe 43, to adjust the angle. The bellows also reduces replacement costs and work intensity.

[0043] Furthermore, the heating unit 3 adopts electric heating, which is more accurate and controllable than other methods, and is clean and pollution-free.

[0044] Furthermore, the first valve 212 and the second valve 222 are both solenoid valves. The solenoid valve itself has a simple structure and a low price, and is easier to install and maintain than other types of actuators such as regulating valves. More significantly, the self-control system formed is much simpler and the price is much lower. Since the solenoid valve is controlled by a switch signal, it is very convenient to connect to an industrial computer. In today's era of popularization of computers and sharp price drops, the advantages of solenoid valves are even more obvious.

[0045] The response time of the solenoid valve can be as short as a few milliseconds, and even the pilot solenoid valve can be controlled within tens of milliseconds. Because it forms its own circuit, it is more sensitive than other automatic control valves. A properly designed solenoid valve coil has very low power consumption and is an energy-saving product. It can also automatically maintain the valve position by simply triggering the action, and it does not consume any power at ordinary times. The solenoid valve has a small size, which saves space and is light and beautiful.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
