The left end of the rack 41 passes through the through groove on the limiting ring 52, and the through groove is opened from the left end surface of the limiting ring 52 to the right end surface. In addition, four gears 51 are rotatably installed on the right end of the cavity screw groove column 5 by using a support rod, and the gears 51 are meshed with adjacent racks 41. An internal thread is opened from the left end of the cavity screw groove column 5 to the inside, and on the left An adjusting screw 6 is rotatably installed at the end, and the left end of the adjusting screw 6 is located outside the cavity screw groove column 5, and a connecting ring 7 is rotatably installed at the left end of the adjusting screw 6, and four L-shaped vertical rods 71 ​​are fixedly installed on the circumferential surface of the connecting ring 7, and a first connecting rod 72 is fixedly installed at one end of the L-shaped vertical rod 71 away from the connecting ring 7, and a detection device 10 is fixedly installed at one end of the first connecting rod 72 away from the L-shaped vertical rod 71, and then, four connecting shafts 9 are fixedly installed at the edge of the opening at the left end of the cavity column 3, and a sliding groove rod 8 is fixedly installed at both ends of the connecting shaft 9, and then, cylinders are fixedly installed on both sides of the detection device 10, and the ends of the cylinders that are away from each other extend to the inside of the sliding groove rod 8;When in use, the cavity column 3 is slidably installed with the detection device 10 inside the combustion chamber 2, and the threaded column 33 is rotated to make the threaded column 33 and the threaded rod 34 in a vertical state, and then the threaded rod 34 is manually rotated to make the ends of the two threaded rods 34 away from each other fit with the inner wall of the shell 1, so that the cavity column 3 maintains a horizontal temperature stable state, and then the combustion chamber 2 is started to operate. When the combustion chamber 2 is operating, the detection device 10 will detect the temperature, so that the detected data can be transmitted to the computer terminal, and then in the process of use , the right end of the cavity column 3 gradually moves away from the shell 1, and in the process of moving away from the shell 1, it will move synchronously with the slide rod 8, and then, in the process of use, the rotating rod 4 also starts to slide to the right. At this time, the rotating rod 4 will move synchronously with the rack 41 during the sliding process, so that the rack 41 can drive the gear 51 to slide the cavity screw groove column 5 to the left, so that the cavity screw groove column 5 can move synchronously with the adjusting screw 6, and in the process of synchronous movement of the adjusting screw 6, it will slide synchronously with the L-shaped vertical rod 71 and the first connecting rod 72 to the left, and During the sliding process, the first connecting rod 72 will move the detection device 10 to the left synchronously, so as to change the position of the detection device 10.

[0036] Specifically, Figures 1 to 7As shown, a limiting ring 52 is fixedly installed on the circumferential surface of the cavity screw groove column 5, and four through grooves are evenly opened from the left end surface to the right end surface of the limiting ring 52. Four gears 51 are rotatably installed on the right end circumferential surface of the cavity screw groove column 5. A rotating rod 4 is slidably installed inside the cavity column 3, and four racks 41 are fixedly installed on the left end surface of the rotating rod 4. The four racks 41 are meshed with adjacent gears 51, and the left end of the rack 41 passes through the through groove on the limiting ring 52. The rack 41 The left end is located on the left side of the limit ring 52, and the end of the L-shaped vertical rod 71 away from the connecting ring 7 is rotatably installed with a first connecting rod 72, and the end of the first connecting rod 72 away from the L-shaped vertical rod 71 is fixedly connected to the detection device 10, and four connecting shafts 9 are fixedly installed on the left end surface of the cavity column 3, and the two ends of the four connecting shafts 9 are fixedly installed with sliding groove rods 8, and cylinders are fixedly installed on both sides of the detection device 10, and the end of the cylinder away from the detection device 10 is slidably installed inside the sliding groove rod 8.

[0037] By adopting the above technical scheme, most of the traditional temperature detection devices 10 on the market can only detect data at one position during use, and in order to obtain average data, the construction personnel need to install multiple temperature devices to obtain the temperature data of the desired position. However, most of the traditional devices on the market are still in a fixed state during use. Therefore, although multiple devices are added during use, they are still essentially in a fixed state and can only detect a certain area, so that the average data of the device has errors; while the present device only needs to rotate the rotating rod 4 during use (wherein, since the temperature inside the combustion chamber 2 is relatively high, and the right end of the combustion chamber 2 is in an open state, therefore, during use, the rotation and adjustment of the rotating rod 4 can be externally provided with a hydraulic telescopic device and a motor, so that the rotating rod 4 can be driven in two different ways: sliding and rotating. The hydraulic device allows the rotating rod 4 to slide, and the motor drives the hydraulic device and the rotating rod 4 to rotate, according to actual needs. Installation of the device), when the rotating rod 4 rotates, it can rotate synchronously with the limit ring 52, and the limit ring 52 will rotate synchronously with the cavity screw groove column 5, so that the length of the adjusting screw 6 can be adjusted, and the adjusting screw 6 can bring the detection device 10 close to or away from the cavity screw groove column 5. Secondly, during use, since the cavity column 3 and the outer rotating shell 35 are in a rotationally connected relationship, during use, the first connecting rod 72 can carry the detection device 10, and the detection device 10 can rotate synchronously with the slide rod 8, so that the slide rod 8 can rotate synchronously with the cavity column 3, so as to realize the rotation of the detection device 10; under the action of the cavity screw groove column 5, the adjusting screw 6 and other structures, the detection device 10 can be rotated in real time, so that multiple detection devices 10 can obtain different temperature data, and then the data of multiple detection devices 10 can be compared to obtain the final average data inside the combustion chamber 2, so as to reduce the error between the data.

[0038] Working principle: First, the threaded column 33 and the threaded rod 34 are in a vertical state, and then the threaded rod 34 rotates so that it can fit with the inner wall of the shell 1, so that the device is in a horizontal and stable state.

[0039] Then, the detection device 10 operates, and the position of the detection device 10 is adjusted. The outer rotating shell 35 slides with the cavity column 3, so that the slide rod 8 can slide synchronously, and then the rotating rod 4 moves in the opposite direction, and then can move with the rack 41, so that the gear 51 moves the left end of the cavity screw groove column 5 to the left.

[0040] Secondly, the rotating rod 4 rotates with the rack 41, and the rack 41 rotates synchronously with the cavity screw groove column 5, so that the adjusting screw 6 can fine-tune the position of the detection device 10.

[0041] Finally, during use, the cavity column 3 inside the outer rotating shell 35 can rotate, so it can rotate synchronously with the slide rod 8, and then the slide rod 8 and the detection device 10 can rotate synchronously.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
