Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-Figure 9 , the present invention provides a technical solution: like Figure 1 and Figure 2 As shown, a temperature-controllable irradiation experimental device includes a control base 100, an irradiation box 200 is arranged on the upper surface of the control base 100, and a temperature-controlled carrier 400 and a driving unit 300 are arranged in the irradiation box 200 for carrying multiple irradiation samples. The driving unit 300 can realize two-dimensional position movement and multi-angle rotation of the temperature-controlled carrier 400, which is convenient for researchers to quickly adjust the sample position and angle according to experimental requirements, adapt to experiments with different irradiation directions and different sample layouts, improve the convenience and efficiency of experimental operations, and reduce experimental preparation time. An adjustment unit 500 for adjusting the radiation dose received by each irradiated sample is arranged on the temperature-controlled carrier 400. Furthermore, the control base 100 includes a base 101, in which a control system 102 and a gas circulation system 103 are arranged. The control system 102 is responsible for coordinating the operation of various components of the device, such as controlling the opening and closing of the irradiation source, adjusting the temperature, driving the motor, etc.; the gas circulation system 103 is used to adjust the air inside the irradiation box 200 to ensure the stability of the environment inside the box, for example, by circulating purified air to remove impurities and moisture that may affect the experiment, or adjusting parameters such as air humidity and oxygen content to meet different experimental requirements. Among them, a temperature control system is also provided in the control base 100 for adjusting the temperature inside the irradiation box 200.

[0017] Furthermore, the irradiation box 200 includes a box 201, and an irradiation source system 202 is arranged on the top of the box 201.

[0018] like Figure 3 As shown, the driving unit 300 includes a driving frame 301 and a moving seat 302 located in the middle of the driving frame 301, two driving rods 303 are sleeved on the moving seat 302, the two driving rods 303 are arranged up and down and the horizontal projections are perpendicular to each other, and moving blocks 304 are arranged at the ends of the driving rods 303, and the moving blocks 304 are slidably connected to the inner wall of the driving frame 301. Two cylinders 305 are arranged on the driving frame 301, which respectively drive the moving blocks 304 connected to different driving rods 303, so that the moving seat 302 can realize two-dimensional movement on the horizontal plane, thereby accurately adjusting the position of the temperature control carrier 400.

[0019] A mounting platform 306 is provided on the upper surface of the movable seat 302, and two fixed plates 307 are provided on the upper surface of the mounting platform 306. The fixed plates 307 are rotatably connected with drive shafts 308, and one end of the two drive shafts 308 is provided with a motor 312. The other ends of the two drive shafts 308 are socketed, and an adjustment seat 309 is fixedly connected to one of the drive shafts 308, and a rotating shaft 310 is rotatably connected to the adjusting seat 309. The bottom end of the rotating shaft 310 and the other drive shaft 308 are provided with a bevel gear 311, and the two bevel gears 311 are meshingly connected. The motor 312 drives the drive shaft 308 to rotate, and through the meshing connection of the bevel gears 311, the rotating shaft 310 is driven to rotate, thereby realizing the angle adjustment of the temperature control carrier 400 to meet the experiments requiring different irradiation angles.

[0020] like Figure 6-Figure 8 As shown, the temperature-controlled carrier 400 includes four carrier platforms 401, which are respectively located in four installation cavities. A placement groove 405 is opened on the upper surface of the carrier platform 401, and the inner wall of the placement groove 405 is coated with a sticky coating, which can effectively fix the sample to prevent it from moving during the experiment and avoid the damage to the sample that may be caused by traditional clamps.

[0021] like Figure 4 and Figure 5 As shown, a heat conducting pipe 402 is provided in each of the carrier platforms 401, a heating wire 403 is provided in the heat conducting pipe 402, a heat conducting sleeve 404 is coated on the outer periphery of the heat conducting pipe 402, a liquid outlet pipe 406 is provided on the water outlet side of the heat conducting pipe 402, the ends of the four liquid outlet pipes 406 extend into the control base 100 and are provided with a collector 407, the water outlet of the collector 407 is connected to a liquid storage tank 411 through a pipe, a liquid inlet pipe 408 is provided on the water inlet side of the heat conducting pipe 402, the ends of the four liquid inlet pipes 408 extend into the control base 100 and are provided with a collector 407, the water outlet of the collector 407 is connected to a liquid storage tank 411 through a pipe, It extends into the control base 100 and is provided with a diverter 409, the water inlet of the diverter 409 is connected to the pump body 410 through a pipeline, the water inlet of the pump body 410 extends to the liquid storage tank 411 through a pipeline, and the liquid inlet pipe 408 is provided with a solenoid valve, and the liquid storage tank 411 is provided with a refrigeration unit. The circulating water system composed of the liquid inlet pipe 408, the liquid outlet pipe 406, the diverter 409, the collector 407, the pump body 410 and the liquid storage tank 411, combined with the refrigeration unit, can achieve accurate temperature control of the sample. The heating wire 403 can quickly provide heat when the temperature needs to be raised, and the circulating water system can efficiently dissipate heat or maintain a constant temperature to meet the experimental needs of different temperature conditions.

[0022] like Fig. 9As shown, the adjustment unit 500 includes a base 501, and a partition 502 is arranged on the upper surface of the base 501. The partition 502 is in a cross-shaped structure. The base 501 is divided into four installation cavities for placing irradiated samples respectively through the partition 502. The setting of the partition 502 can effectively avoid the influence caused by the temperature difference between two adjacent carriers 401, and improve the accuracy of the experimental results. A carrier frame 503 is arranged on the upper surface of the base 501, and a driving motor 504 is arranged on the top of the inner wall of the carrier frame 503. The output shaft of the driving motor 504 extends to the top of the carrier frame 503 and is provided with an adjustment platform 505. The adjustment platform 505 is in a cross-shaped structure. The side of the adjustment platform 505 is plugged with a particle radiation absorber 507 through a plurality of slots 506. The adjusting platform 505 is driven by the driving motor 504 to rotate, and the particle radiation can be flexibly changed. The position of the radiation absorber 507 is adjusted to adjust the radiation dose received by the sample. For example, when conducting a particle irradiation experiment, according to the experimental design, the particle irradiation absorber 507 is inserted into different slots to block or weaken the particle irradiation in a specific direction, wherein the thickness of the particle irradiation absorber 507 is set according to the experimental design to achieve fine regulation of the irradiation dose of each sample. In one embodiment, such as in a high-energy electron irradiation experiment, aluminum foil of different thicknesses is used as the particle irradiation absorber 507. The aluminum foil absorbs part of the energy of the electrons, so that the energy of the electrons irradiated on the sample after passing through the aluminum foil is reduced, and the dose is reduced; in another embodiment, such as in an irradiation experiment related to photosynthesis, filters of different colors and optical densities are used to simulate the lighting conditions in different environments, adjust the light irradiation dose, and study the response of plants to different light qualities and light quantities.

[0023] The working process of this embodiment is as follows: the samples to be irradiated are placed in the placement grooves 405 of the four carriers 401 of the temperature-controlled carrier 400 respectively, and the samples are fixed by the adhesive coating to ensure that the samples are in close contact with the carriers 401. The irradiation parameters of the irradiation source system 202 are set according to the experimental requirements, such as irradiation intensity, irradiation time, the start mode of the irradiation head (single or multiple coordinated), etc., and the temperature parameters of the temperature-controlled carrier 400 are set, including the target temperature, heating rate, cooling rate, etc. At the same time, according to the requirements of the sample for the irradiation dose, the control system 102 controls the driving motor 504 of the adjustment unit 500 to adjust the position of the particle irradiation absorber 507, preliminarily set the irradiation dose adjustment plan for each sample, and start the device. The gas circulation system 103 is first operated to adjust the air environment in the irradiation box 200. Then, the irradiation source system The system 202 starts irradiation according to the set parameters, and the temperature-controlled carrier 400 performs heating or cooling operations according to the temperature setting. The driving unit 300 adjusts the position and angle of the temperature-controlled carrier 400 in time according to the experimental progress. During the experiment, the control system 102 monitors various parameters in real time, such as irradiation dose, sample temperature, gas environment parameters, etc., and automatically adjusts the operating status of the device according to the feedback information to ensure that the experiment is always carried out according to the predetermined plan. When the set irradiation time or other experimental end conditions are reached, the irradiation source system 202 stops irradiation, and the temperature-controlled carrier 400 maintains the current temperature for a period of time, and then gradually stops heating or cooling. The gas circulation system 103 continues to operate for a period of time to discharge the gas or impurities generated during the experiment that may affect subsequent experiments. Finally, the power of the device is turned off, the sample is taken out, and subsequent detection and analysis are carried out.
