[0002] High-pressure thermogravimetric experiments are based on the principle of thermogravimetric analysis. They analyze the thermal properties and chemical changes of samples by measuring the mass changes of samples during programmed heating or constant temperature. Under conditions within 10MPa, the experiment can simulate the environment of the material in actual application and provide data that is closer to the actual situation.

A second limiting shaft 1042 is provided, and a first conveyor belt 103 is wrapped around the first limiting shaft 1041 and the two second limiting shafts 1042. Open grooves 110 are provided at the edge positions on both sides of the upper scraper 11 and the lower scraper 12 along the conveying direction. The cleaning rod 101 is connected to the first conveyor belt 103 below through the connecting block 102. The driving shaft 109 drives the second limiting shaft 1042 at the end of the upper scraper 11 to rotate through the second conveyor belt 108. A plurality of transmission components are provided in a circumferential array on the outer edge of the slide plate 203. The transmission component includes a connecting shaft 2 fixedly connected to both ends of the driving shaft 109 and fixedly connected to the upper scraper 11, and a rack 202 vertically arranged between the driving shaft 109 and the slide plate 203. A tooth root 201 meshing with the rack 202 is provided on the driving shaft 109. The rack 202 moves vertically through the rotation of the rotating handle 801.

[0023] The specific implementation process of the present invention is that when cleaning the pipeline, the handle 801 can be first turned to make the first screw 501 move down along the threaded sleeve 5. At this time, the threaded sleeve 5 is fixed to the first screw 501. At this time, the handle 801 is slid down and turned to drive the rack 202 on the slide plate 203 to engage with the annular gear 201, thereby driving the rotation of the drive shaft 109. The rotation of the drive shaft 109 can drive the second transmission belt 108 to drive the rotation of the second limiting shaft 1042. The rotation of the second limiting shaft 1042 can drive the first conveyor belt 103 to transmit During the transmission process, the cleaning rod 101 on the scraper 1 cleans the inclined surface that is not in contact with the inner wall of the pipe. At this time, the rack 202 is meshed with the upper side of the annular gear 201 to lock the drive shaft 109, and the first screw 501 is continuously rotated so that the first screw passes through the threaded sleeve 5. At this time, the second screw 505 and the water pipe 6 move downward. During the downward movement of the water pipe 6, the stopper 604 on the water storage tank 605 abuts against the gravity block 603 to slide the water stop plate 602, thereby releasing the cleaning liquid, so that the cleaning liquid The brush 702 is soaked through the through hole 701 through the water storage tank 605 to clean the inner wall of the pipe; when the cleaning liquid is discharged, the movable frame 902 can be pressed down to slide, and the sliding of the movable frame 902 drives the pressing block 903 to slide. During the sliding process of the pressing block 903, the cleaning liquid inside the water inlet pipe 8 is squeezed out, and then enters the inner wall of the movable plate 904 through the water inlet 912, and then enters the inner wall of the movable plate 904 along the channel between the first adjusting plate 909 and the second adjusting plate 908 to the water outlet 910, and flows along the The water outlet 910 enters the first screw 501 for cleaning. After cleaning, in order to prevent the sewage from flowing back, the limit block 9 can be pressed downward to drive the pull rod 901 and the movable plate 904 fixedly connected thereto to slide downward. During the downward sliding of the movable plate 904, the limit groove 911 set on its inner wall and the driving rotation shaft 905 rotate, thereby driving the first adjustment plate 909 and the second adjustment plate 908 to rotate, so that the distance between the adjustment plates becomes smaller until it is closed, thereby blocking the sewage and preventing it from flowing back. The beneficial effects of the present invention are as follows: the rack on the sliding handle slide is meshed with the teeth, thereby driving the rotation of the rotating shaft, and the rotation of the rotating shaft can drive the transmission belt to drive the rotation of the limiting shaft, and the rotation of the limiting shaft can drive the first conveyor belt to transmit, and during the transmission process, the cleaning rod on the scraper cleans the inclined surface that is not in contact with the inner wall of the pipe; the block on the water storage tank abuts against the gravity block to achieve the sliding of the water stop plate, and then the release of the cleaning liquid is achieved, so that the cleaning liquid passes through the water storage tank through the through hole to soak the brush, thereby cleaning the inner wall of the pipe; by sliding the movable plate downward, the limiting groove on its inner wall is rotated with the driving rotating shaft, thereby driving the first adjustment plate and the second adjustment plate to rotate, so that the distance between the adjustment plates becomes smaller until it is closed, thereby blocking the sewage and preventing it from flowing back.

[0024] In the present invention, both ends of the limiting shaft 104 are rotatably connected to the fixing block 105 , and the first limiting shaft 1041 and the second limiting shaft 1042 are movably connected to the inner walls of the upper scraper 11 and the lower scraper 12 through the fixing block 105 .

A movable shaft 4 is fixedly connected to the side of the spring rod 303 away from the slide plate 203, and the two ends of the movable shaft 4 are rotatably connected to the connecting shaft 2, there are multiple movable shafts 4, and the multiple movable shafts 4 are rotatably connected to the connecting shaft 2 to form a closed loop. The collecting trough 3 arranged on the upper surface of the slide plate 203 is used to collect scraped foreign matter. After the cleaning rod 101 cleans the foreign matter on the scraper 1 on the upper inclined surface, it is scraped to the collecting trough 3 for collection. The multiple slide grooves 301 in the annular array on the outer surface of the slide plate 203 can facilitate the sliding of the slider 302. The slider 302 is used to connect the spring rod 303, and the spring rod 303 is used to connect the movable shaft 4 and the slide plate 302. In addition, during the adjustment process, the spring rod 303 can be retracted to prevent the scraper 1 from getting stuck during the adjustment process. The movable shaft 4 fixedly connected to the spring rod 303 away from the surface of the slide plate 203 is used to connect the shaft 2 and support it.

[0026] In the present invention, the upper surface of the slide plate 203 is fixedly connected with a threaded sleeve 5, the inner wall of the threaded sleeve 5 is threadedly connected with a first screw rod 501, the lower end of the first screw rod 501 is fixedly connected with a reducer 502, the outer surface of the reducer 502 has a plurality of blocks 503 in an annular array, the inner wall of the slide plate 203 is provided with a slot 504, and the lower end of the reducer 502 is fixedly connected with a second screw rod 505.

The lower surface of the gravity block 603 abuts against the block 604. The side of the block 604 away from the water pipe 6 is fixedly connected to the water storage tank 605. The block 604 abutted against the lower surface of the gravity block 603 can realize the release of the cleaning liquid in the water pipe 6. When releasing, the water hanging pipe 6 slides downward, causing the gravity block 603 to abut against the baffle 604, thereby causing the water stop plate 602 to slide, so that the opening 601 is enlarged, and the cleaning liquid inside the water pipe 6 is released. The cleaning liquid enters the flushing plate 7 and enters the brush 702 through the through hole 701 to be soaked.
