[0028] In this embodiment, the fixing mechanism includes two fixing seats 5, two extrusion rods 8, two pressing blocks 9, two first springs 10, two connecting plates 11, two second springs 13 and two locking blocks 14. The two fixing seats 5 are fixedly installed on the left and right sides of the tube body 1 respectively. The tops of the two fixing seats 5 are both provided with locking grooves 6. The two locking grooves 6 are provided with through holes 7 on the sides away from each other. The two extrusion rods 8 are respectively slidably installed in the two through holes 7. The sides away from each other of the two extrusion rods 8 extend to the outside of the corresponding through holes 7 respectively. The two pressing blocks 9 are respectively fixedly installed on the sides away from each other of the two extrusion rods 8. The two first springs 10 are respectively sleeved on the two extrusion rods 8. The two first springs 10 are used to push the two pressing blocks 9 and the two extrusion rods 8 away from each other, so as to facilitate the two locking blocks 14. Slide into the two through holes 7, the ends of the two first springs 10 that are away from each other are fixedly connected to the two pressing blocks 9 respectively, and the ends of the two first springs 10 that are close to each other are fixedly connected to the two fixing seats 5 respectively, the two connecting plates 11 are fixedly installed on the left and right sides of the arc cover plate 3 respectively, and the bottoms of the two connecting plates 11 are slidably installed in the two locking grooves 6 respectively, and the two connecting plates 11 are provided with a receiving groove 12 on the side away from each other. The two second springs 13 are fixedly installed in the two receiving grooves 12 respectively, and the two second springs 13 are used to push the two locking blocks 14 away from each other.

[0029] In this embodiment, the tops and bottoms of the two through holes 7 are each provided with a first limiting groove 17, the tops and bottoms of the two extrusion rods 8 are each fixedly installed with a first limiting block 18, and the four first limiting blocks 18 are respectively slidably installed in the corresponding first limiting grooves 17, the tops and bottoms of the two storage grooves 12 are each provided with a second limiting groove 19, the tops and bottoms of the two locking blocks 14 are each fixedly installed with a second limiting block 20, and the four second limiting blocks 20 are respectively slidably installed in the corresponding second limiting grooves 19.

[0030] In this embodiment, arc-shaped fixing plates 21 are fixedly installed on the inner walls on both sides of the front and rear sides of the above-mentioned incision groove 2, the tops of the two arc-shaped fixing plates 21 are in close contact with the arc-shaped cover plate 3, and arc-shaped sealing strips 22 are fixedly installed on the tops of the two arc-shaped fixing plates 21. Two symmetrically distributed strip sealing strips 23 are fixedly installed on the bottom inner wall of the incision groove 2, and the two strip sealing strips 23 are connected end to end with the two arc-shaped sealing strips 22. A sealing groove 24 is provided at the bottom of the arc-shaped cover plate 3, and the two arc-shaped sealing strips 22 and the two strip sealing strips 23 are slidably installed in the sealing groove 24. Through the above-mentioned arrangement, the compressive strength of the arc-shaped cover plate 3 can be greatly improved, and the sealing performance of the arc-shaped cover plate 3 can be improved.

[0031] Two pressure sensors 25 are fixedly installed on the annular inner wall of the pipe body 1. The two pressure sensors 25 are respectively located on the front and rear sides of the sieve plate 4 and are symmetrically distributed. By setting a display screen connected to the two pressure sensors 25 in the control room that controls the pipeline transportation, the pressure on the front and rear sides of the sieve plate 4 can be intuitively understood, which is convenient for maintenance workers to judge whether the pipe body 1 is blocked. If the two pressure values ​​are close, the pipe body 1 is not blocked. If the two pressure values ​​are very different, the pipe body 1 has been blocked and needs to be unblocked immediately. A positioning groove 26 is opened on the bottom inner wall of the pipe body 1, and the bottom of the sieve plate 4 is slidably installed in the positioning groove 26.

[0032] In this embodiment, a control switch is provided in the central control room for controlling pipeline transportation. The control switch, the sealed drive box 15, and the two pressure sensors 25 are electrically connected to the power line in sequence through wires. The operation and shutdown of the sealed drive box 15 and the two pressure sensors 25 can be controlled by the control switch.

[0033] When the pipe is blocked or fails, the two connecting plates 11 can be easily unlocked and the curved cover plate 3 can be opened for processing. When the pipe is operating normally, the sieve plate 4 can be cleaned by using a plurality of brush rods 16, so that the pipe can operate normally and the curved cover plate 3 can be avoided to be opened, thereby improving the anti-blocking performance of the pipe. When in use, the sealing drive box 15 is controlled to operate periodically, and the sealing drive box 15 drives a plurality of brush rods 16 to rotate to clean the sieve plate 4 and the curved cover plate 3 can be avoided to be opened, thereby ensuring the normal operation of the pipe. When the on-duty personnel find that the pressure values ​​of the two pressure sensors 25 are greatly different, it indicates that the pipe is blocked. The delivery valve is closed and a maintenance worker is called to arrive at the pipe body 1 where the two pressure sensors 25 are set. The two pressing blocks 9 are pressed at the same time. The two pressing blocks 9 are close to each other and push the two locking blocks 14 to retract into two storage containers. The two first springs 10 and the two second springs 13 are in a compressed state at this time, and the lock of the two connecting plates 11 is released. The arc cover plate 3 is lifted upward by the handle 27 to open the cutout groove 2. Under the push of the two first springs 10, the two pressing blocks 9 return to the initial position, and the sieve plate 4 is taken out of the tube body 1 along with the arc cover plate 3. The sieve plate 4 is carefully cleaned. After the inner wall of the tube body 1 is cleaned, the arc cover plate 3 is snapped into the cutout groove 2 again and the sieve plate 4 is removed. The bottom of the plate 4 is slidably installed in the positioning groove 26. As the arc cover plate 3 descends, the bottoms of the two connecting plates 11 slide into the two locking grooves 6 respectively, and the two locking blocks 14 are pushed and retracted into the two receiving grooves 12, while squeezing the two second springs 13. When the two receiving grooves 12 are respectively aligned with the two through holes 7, the two locking blocks 14 slide into the two through holes 7 under the push of the two second springs 13, completing the locking of the two connecting plates 11, that is, completing the installation and fixation of the arc cover plate 3.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
