[0047] When the rotating shaft 14 is working, the second bevel gear 20 will be driven to rotate through the first bevel gear 19, and then the transmission shaft 21 will drive the fan blades 24 to rotate through the plug rod 22 and the plug tube 23, so that the fan blades 24 draw the gas at the top between the partitions 8 into the bottom, so that the gas between the partitions 8 is in a flowing state, and in this process, due to the exhaust and suction operation of the exhaust pipe 33 into the second gas injection pipe 35, and the second gas injection pipe 35 is connected to the fixed sleeve 26, the connecting plate 27 will slide up and down along the fixed sleeve 26 under the action of air pressure, so that the plug tube 23 moves up and down, so that the fan blades 24 move up and down;

[0048] It can ensure the circulation efficiency of the gas inside the measuring tube 1 and the measuring sleeve 2. At the same time, due to the up and down sliding of the plug-in tube 23 on the plug-in rod 22, the fan blades 24 produce a more uniform airflow distribution, which helps to eliminate airflow dead corners and improve the flow efficiency of the gas in the measuring tube 1 and the measuring sleeve 2, thereby ensuring the uniformity of the internal temperature of the measuring tube 1 and the measuring sleeve 2, preventing heat from accumulating between the detector and the sensor, and affecting the service life of the detector and the sensor.

[0050] During the process of exhausting and drawing air from the exhaust pipe 33 into the first air injection pipe 34, the slide plate 37 will slide up and down under the action of the air pressure and the elastic force of the return spring 38, and then the adjustment ring 40 will slide up and down through the lifting rod 39, so that the adjustment ring 40 intermittently reduces the distance between the spiral plates 18;

[0051] The flow rate of the medium is in a changing state, so that the impact force of the medium on the blockage in the drill bit is in a changing state. The changing impact force can cause irregular impact on the blockage, thereby increasing the probability of flushing it open, preventing the drill bit from being blocked, affecting the cooling efficiency of the medium on the measuring system, and thus reducing the temperature of the measuring system during operation.
