[0050] A method for impregnating a cylindrical carbon-carbon composite material impregnation device, the specific steps of the method are as follows:

[0051] S1. First, a specified amount of impregnation liquid is injected into the impregnation tank 1 by controlling the external solenoid valve to open the liquid inlet pipe 3, and then the cylindrical carbon-carbon composite material body 18 to be impregnated is evenly clamped and placed between the limit clamps 25;

After the treatment is completed, the cylindrical carbon-carbon composite material body 18 is reset and raised, and the drain pipe 4 is opened by controlling the external solenoid valve to discharge the impregnation liquid in the impregnation tank 1.

[0056] Working principle: First, the external electromagnetic valve is controlled to open the liquid inlet pipe 3 to inject a specified amount of impregnation liquid into the impregnation box 1, and then the cylindrical carbon-carbon composite material body 18 to be impregnated is evenly clamped and placed between the limit clamps 25, and the first motor 7 is started to drive a second synchronous rotating wheel 21 and a second adjusting gear 20 to rotate.

After the treatment is completed, the cylindrical carbon-carbon composite material body 18 is reset and raised, and the drain pipe 4 is opened by controlling the external electromagnetic valve to discharge the impregnation liquid in the impregnation box 1. Since an observation window 28 is fixedly provided at the middle part of the outer end of the impregnation box 1, the clamping moving part 17 provided on both sides of the observation window 28 can accurately and conveniently observe the liquid level of the impregnation liquid in the impregnation box 1, which is convenient for accurately adjusting the impregnation liquid to the interior of the impregnation box 1. The device can make the cylindrical carbon-carbon composite material body that needs to be impregnated be provided with a limit support device 5. The carbon composite body 18 is raised and lowered synchronously, and the cylindrical carbon-carbon composite body 18 can be completely immersed in the impregnation liquid in the impregnation box 1, and the cylindrical carbon-carbon composite body 18 will not float in the impregnation liquid, so that the impregnation is sufficient and fast, and the cylindrical carbon-carbon composite body 18 can be conveniently lifted and taken out of the impregnation box 1 during the impregnation process. By setting the clamping and fixing device 6, the clamping and fixing device 6 can complete the impregnation treatment of multiple cylindrical carbon-carbon composite bodies 18 at one time, and the impregnated cylindrical carbon-carbon composite bodies 18 are evenly distributed, so that the cylindrical carbon-carbon composite bodies 18 will not affect each other during the impregnation process, and the cylindrical carbon-carbon composite body 18 can be firmly fixed during the impregnation process.By tightening the fastening bolts 26 and controlling the squeezing force between the fastening bolts 26 and the sliding mounting frame 23, the movable adjustment frame 24 and the limit clamp 25 can be controlled and adjusted along the sliding mounting frame 23. This allows the use position of the limit clamp 25 to be adjusted, thereby allowing the position of the cylindrical carbon-carbon composite material body 18 impregnated in the impregnation tank 1 to be adjusted and controlled.
