Description

Technical Field

[0001] The present disclosure relates to the technical field of pneumatic conveying, and in particular to an anti-blocking suction pipe, a suction vehicle and an anti-blocking control method. Background Art

[0002] Pneumatic conveying is an important way to transport powder, block and non-fluid materials. This method uses airflow as a conveying medium to transport materials from one or more sources to one or more destinations. Using pneumatic conveying equipment for soil suction operations can achieve non-mechanical contact and non-destructive removal. The tank body of the pneumatic conveying equipment (for example, a suction truck) can be used in conjunction with a suction pipe, and is mainly used in landslide, mud and rock flow rescue or silt removal operations. In order to draw soil, gravel, etc. into the tank body, a large wind speed needs to be provided in the suction pipe, so that the soil, gravel, etc. move at high speed in the pipe. Such as Figure 1 As shown, the suction pipe 1' has a bent pipe section 11' near the tank body 2', which causes the water-containing soil to easily adhere to the inner wall of the bent pipe section 11' during high-speed movement. Under the high-speed impact of the water-containing soil, the adhered soil blocks at the bent pipe section 11' are extremely dense and hard, difficult to clean, and gradually block the pipeline, which not only affects the transportation efficiency but also easily causes damage to the equipment.

[0003] In the related art, a connecting rod mechanism with a spring is provided to prevent the suction pipe from being blocked. Figure 2 It is an anti-blocking conveying equipment of related technology. A vibrating mechanism 27 is arranged on the inner wall of the horizontal pipe end of the discharge pipe 26. When the material is conveyed in the discharge pipe 26, the material pushes the vibrating mechanism 27 to vibrate under the action of the first spring 277. The back-and-forth motion caused by the first spring 277 under the impact of the cement drives the puncture structure 278 to repeatedly sprint and vibrate the cement in the discharge pipe 26. In addition, a clearing piece 28 is arranged on the inner wall of the vertical pipe of the discharge pipe 26 opposite to the end of the puncture structure 278. The clearing piece 28 also punctures and clears the cement under the action of the end of the puncture device 278. However, the connecting rod mechanism uses the material driving force as the power source and is not suitable for pneumatic conveying equipment with high-speed airflow as the conveying medium.

[0076] An embodiment of the present disclosure provides a blockage-resistant suction pipe, comprising a pipe body 1 and a blockage-resistant device. The pipe body 1 includes a first pipe section 11, a second pipe section 12, and a curved pipe section 13 connecting the first and second pipe sections 11, 12. The end of the first pipe section 11 distal to the curved pipe section 13 forms an inlet 1A, and the end of the second pipe section 12 distal to the curved pipe section 13 forms an outlet 1B. For example, the first and second pipe sections 11, 12 extend perpendicularly. The blockage-resistant suction pipe draws suction air from the inlet 1A through the curved pipe section 13 to the outlet 1B, thereby transporting water-bearing soil.

[0077] The anti-blocking device is arranged in the bend section 13 and includes at least one dividing part 2. The dividing part 2 includes a dividing driving part 21 and a dividing base plate 22. The dividing driving part 21 can be, for example, a rod-shaped body with a cross-section of any shape. The dividing driving part 21 is driven and connected to the dividing base plate 22, and is configured to drive the dividing base plate 22 to move in a first direction so that the dividing base plate 22 switches between a reset state and a cutting state. For example, the first direction is the same as the extension direction of the second pipe section 12. For another example, the dividing base plate 22 is perpendicular to the first direction. In the reset state, the dividing base plate 22 avoids the internal space of the bend section 13. In the cutting state, the dividing base plate 22 is located in the internal space of the bend section 13.

[0078] Providing an anti-blocking device within the curved section 13 of the pipe body 1 can reduce direct contact between the inner wall of the pipe body 1 and the water-bearing soil, thereby reducing the adhesion of the water-bearing soil to the inner wall of the pipe body 1. Furthermore, the anti-blocking device provided in the anti-blocking suction pipe includes at least one dividing portion 2, and a dividing drive portion 21 of the dividing portion 2 is provided within the curved section 13 of the pipe body 1 to drive the dividing base plate 22 to move in a first direction, thereby facilitating flexible control of the switching of the dividing base plate 22 between a reset state and a cutting state. During the switching process, the dividing base plate 22 of the dividing portion 2 can divide the water-bearing soil adhering to the curved section 13 and remove the water-bearing soil in cooperation with the suction airflow or the suction airflow and the gravity of the water-bearing soil itself, thereby effectively preventing the water-bearing soil from clogging the pipeline and improving the operating efficiency and service life of the anti-blocking suction pipe.

[0079] In some embodiments, the anti-blocking device further includes a first separation portion 3 disposed within the curved pipe section 13. The first separation portion 3 includes at least one first protrusion 31, which is configured to create a porous structure within the water-bearing soil adhering to the inner wall of the curved pipe section 13. This configuration further reduces the strength of the water-bearing soil adhering to the pipe body 1, thereby facilitating separation of the water-bearing soil by the segmentation portion 2.

[0080] In some embodiments, the first separating part 3 comprises a plurality of first protruding parts 31 and a first separating driving part 32. For example, the first protruding part 31 can be a cylinder or a cone with any cross-sectional shape. For another example, the first protruding parts 31 can be arranged in a row. The first separating driving part 32 is drivingly connected with the first protruding part 31 and drives the first protruding part 31 to move in the first direction to switch the first protruding part 31 between the first protruding state and the first avoiding state. In the first protruding state, the first protruding part 31 is located in the inner space of the elbow pipe section 13. In the first avoiding state, the first protruding part 31 avoids the inner space of the elbow pipe section 13. For example, one first separating driving part 32 can correspond to one first protruding part 31. For another example, one first separating driving part 32 can correspond to a plurality of first protruding parts 31.

[0081] The first protruding part 31 is provided and has the first protruding state, which is beneficial to form a pore structure in the cohesive water-bearing soil in the elbow pipe section 13, reduce the structural strength of the cohesive water-bearing soil, and facilitate the separating part 2 to separate and remove the cohesive water-bearing soil. In addition, the first protruding part 31 is provided in the first avoiding state, which is beneficial to reduce the friction of the separating bottom plate 22 in the switching process and provide sufficient flow space for the suction airflow.

[0082] In some embodiments, the separating bottom plate 22 is provided with a bottom plate through hole 22A through which the first protruding part 31 passes. This structure is simple, beneficial to compact the structure of the anti-blocking device, reduce the installation space of the device, and thus facilitate the flow of the suction airflow and the cleaning of the water-bearing soil.

[0083] In some embodiments, the separating bottom plate 22 comprises a plurality of bottom plate through holes 22A, and at least part of the plurality of first protruding parts 31 are provided in one-to-one correspondence with the plurality of bottom plate through holes 22A. The cross section of the first protruding part 31 corresponding to the bottom plate through hole 22A and perpendicular to the first direction is matched with the cross section of the corresponding bottom plate through hole 22A and perpendicular to the first direction, so that the first protruding part 31 moves in the first direction by passing through the corresponding bottom plate through hole 22A during the movement of the first protruding part 31 driven by the first separating driving part 32.

[0084] The cross section of the first protruding part 31 of the first separating part 3 and perpendicular to the first direction is matched with the bottom plate through hole 22A of the separating part 2, which is simple in structure and beneficial to the first separating driving part 32 driving the first protruding part 31 in the first direction. In addition, the first protruding part 31 is arranged to move through the bottom plate through hole 22A, so that the separating part 2 and the first separating part 3 are spatially coincident, which is compact in structure and beneficial to save structural space.

[0085] In some embodiments, the first protrusion 31 includes a short protrusion 311 and a long protrusion 312. The length of the long protrusion 312 is greater than the length of the short protrusion 311. The lengths of the short protrusions 311 may be the same or different. The length of the short protrusion 311 may range from 1 / 6 to 1 / 4 of the longest distance of the inner wall cross section of the first pipe segment 11 along the first direction. The first protrusion 31 on the edge of the dividing bottom plate 22 that is not connected to the inner wall of the tube body 1 and at a position corresponding to the bottom plate through hole 22A closest to the edge is set as the long protrusion 312. The lengths of the long protrusions 312 may be the same or different. The length of the long protrusion 312 may range from 1 / 4 to 2 / 3 of the longest distance of the inner wall cross section of the first pipe segment 11 along the first direction. The provision of the long protrusion 312 is beneficial for separating the water-containing soil into multiple pieces during the bonding process of the water-containing soil, thereby reducing the bonding strength. In addition, the provision position of the long protrusion 312 is beneficial for reducing the shear strength required for the dividing part 2 to cut the bonded water-containing soil, thereby reducing the driving force required for the dividing driving part 21 and saving energy consumption.

[0086] In some embodiments, the long protrusions 312 are arranged in one or more rows. In some embodiments, at least a portion of the long protrusions 312 are evenly spaced. In some embodiments, the first protrusion 31 includes at least two rows of long protrusions 312, and in the at least two rows of long protrusions 312, the length of the long protrusions 312 decreases as they are closer to the inlet 1A.

[0087] The long protrusions 312 are arranged in rows, each row having different lengths, to coordinate with the flow direction of the suction airflow, thereby facilitating the flow of the suction airflow. Furthermore, this arrangement, based on the spatial structure of the curved pipe section 13, places the longer long protrusions 312 where the thickness of the bonded water-bearing soil is greater. This helps reduce the bond strength at locations with greater water-bearing soil thickness, facilitating the cutting of the dividing base plate 22 near thick water-bearing soil.

[0088] In some embodiments, the anti-blocking suction pipe includes a first accommodating cavity 14, located on the side of the curved pipe section 13 away from the second pipe section 12 and communicating with the curved pipe section 13. The inner wall of the first accommodating cavity 14 forms a first accommodating space, within which the splitting drive unit 21 and the first separation drive unit 32 are disposed. This arrangement prevents the splitting drive unit 21 and the first separation drive unit 32 from prolonged contact with water-containing soil in the suction airflow, thereby extending the service life of the device.

[0089] In some embodiments, the anti-blocking device includes at least two dividing sections 2, with the dividing bottom plates 22 of the at least two dividing sections 2 connected to form a dividing section bottom plate. A cross-section of the dividing section bottom plate perpendicular to the first direction is at least partially identical in shape to a cross-section of the inner wall of the first accommodating cavity 14 perpendicular to the first direction, and slidably engages with the inner wall of the first accommodating cavity 14. This arrangement facilitates compatibility of the dividing section 2 with different models of tubular bodies 1, thereby expanding the range of uses of the anti-blocking device. This arrangement also facilitates compactness of the structure and facilitates the segmentation drive unit 21 guiding the movement of the dividing bottom plate 22 in the first direction.

[0090] In some embodiments, the adjacent split bottom plates 22 have open slots on their edges, and two adjacent open slots are joined to form a single bottom plate through hole 22A. For example, the two open slots can be semicircular in shape and size, and join at their openings to form a circular bottom plate through hole 22A. This arrangement is structurally simple, facilitates full utilization of the space in the split bottom plates 22, and facilitates the provision of more first protrusions 31.

[0091] In some embodiments, the first separation portion 3 further includes a first separation frame. The first separation frame can be perpendicular to the first direction, and the first protrusion 31 is arranged on a side of the first separation frame close to the outlet 1B. The first separation drive portion 32 is drive-connected to the first separation frame and is configured to drive the first separation frame to move in the first direction so that the first protrusion 31 switches between the first extended state and the first avoidance state. For example, the first separation frame can be a plurality of long plates, rod-shaped structures or rectangular parallelepipeds arranged side by side, etc., to drive the first protrusion 31 to move in the first direction in different areas. For another example, the first separation frame can be a plate or a cube, etc.

[0092] Providing the first separation frame perpendicular to the first direction facilitates the first separation driving portion 32 to drive the plurality of first protrusions 31 to move simultaneously in the first direction, thereby reducing the number of first separation driving portions 32 provided.

[0093] In some embodiments, the first separation frame includes a first separation plate 33, with the first protrusion 31 disposed on the first separation plate 33. This arrangement facilitates the first separation drive 32 driving the first protrusion 31 to move simultaneously in the first direction and reduces the number of first separation drive 32 components. Furthermore, the first separation plate 33 has a simple structure, facilitating easy manufacture and reducing manufacturing costs.

[0094] In some embodiments, the first accommodating space has a uniform cross-section along the first direction. The segmenting portion 2 further includes a guide connector 23 that connects the segmenting drive portion 21 and the segmenting base plate 22. The guide connector 23 has a surface that mates with the inner wall of the first accommodating cavity 14. This allows the segmenting drive portion 21 to drive the guide connector 23, driving the segmenting base plate 22 in the first direction. This arrangement is simple in structure, facilitates guiding the segmenting base plate 22 in the first direction, and improves the driving stability of the segmenting drive portion 21.

[0095] In some embodiments, at least one guide connector 23 further includes a hole 23A, through which the first separation drive 32 passes, and can drive the first separation frame to move in the first direction. For example, the first separation drive 32 can have a rod-shaped structure with a cross-section that aligns with the shape of the hole 23A, so that the first separation drive 32 drives the first separation plate 33 to move in the first direction. This arrangement is simple and helps ensure that the first separation plate 33 does not deviate from the first direction during movement.

[0096] In some embodiments, a cross-section of the outer wall of the first separation frame perpendicular to the first direction is at least partially identical in shape to a cross-section of the inner wall of the guide connector 23 perpendicular to the first direction, and slides in engagement with the inner wall of the guide connector 23. This arrangement is structurally simple, forming a moving pair between the first separation frame and the guide connector, which helps prevent the first separation frame from deviating from the first direction during movement. This arrangement also facilitates the first separation frame's compatibility with guide connectors having inner walls of varying shapes, thereby expanding the range of uses for the first separation frame.

[0097] In some embodiments, the anti-blocking suction pipe also includes a wind pressure detection device, and the wind pressure detection device includes a first wind pressure sensor 51 and a second wind pressure sensor 52. The first wind pressure sensor 51 is configured to detect the wind pressure at the inlet 1A, and the second wind pressure sensor 52 is configured to detect the wind pressure at the outlet 1B. The segmentation drive unit 21 drives the segmentation base plate 22 to move in the first direction according to the detection result of the wind pressure detection device. The detection result is the wind pressure difference detected by the second wind pressure sensor 52 and the first wind pressure sensor 51. For example, a first wind pressure difference indicating that the anti-blocking suction pipe is blocked can be set. When the detection result is greater than the first wind pressure difference, the segmentation drive unit 21 starts to drive the segmentation base plate 22 to move in the first direction. This setting is conducive to automatically monitoring the blockage of the anti-blocking suction pipe, and is conducive to realizing automated operation of the equipment and reducing labor costs.

[0098] In some embodiments, the anti-blocking suction pipe further includes a controller. The controller is signal-connected to the wind pressure detection device and the segmentation drive unit 21 and is configured to control the operation of the segmentation drive unit 21 based on the detection results of the wind pressure detection device. The provision of a controller facilitates centralized control of the segmentation drive unit 21 and facilitates flexible control of the driving force, driving speed, and driving range of the segmentation drive unit 21 to meet the needs of different blockage conditions.

[0099] In some embodiments, the controller described above can be implemented as a general-purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or any appropriate combination thereof for performing the functions described in the present disclosure.

[0100] In some embodiments, the anti-blocking device includes two or more dividing sections 2. The two or more dividing sections 2 are arranged sequentially from the side closest to the inlet 1A to the side further away from the inlet 1A. The controller is configured to sequentially drive the dividing base plate 22 in a first direction from the side closest to the inlet 1A to the side further away from the inlet 1A to switch between a reset state and a cutting state. This arrangement facilitates flexible control of the cutting operation of the dividing sections 2, reduces the driving force of the dividing drive section 21 in areas with a small accumulation of water-bearing soil, and facilitates the removal of water-bearing soil adhering to the bend section 13 in separate areas.

[0101] In some embodiments, the anti-blocking device further comprises a second separating part 4. The second separating part 4 comprises a plurality of second protruding parts 41 and a second separating driving part 42. The second separating driving part 42 is drivingly connected with the plurality of second protruding parts 41 and is configured to drive the second protruding parts 41 to move in a second direction which is at an angle with the first direction to switch the second protruding parts 41 between the second protruding state and the second avoiding state. For example, the angle can be in a range of 45° to 135°. For another example, one second separating driving part 42 can drive one second protruding part 41, or one second separating driving part 42 can drive a plurality of second protruding parts 41 simultaneously. The second direction can be the same as the extending direction of the second pipe segment 12. In the second protruding state, the second protruding parts 41 are located in the inner space of the elbow pipe segment 13. In the second avoiding state, the second protruding parts 41 avoid the inner space of the elbow pipe segment 13. The length of the second protruding part 41 can be in a range of 1 / 6 to 1 / 4 of the longest distance of the inner wall cross section of the second pipe segment 12 along the second direction.

[0102] The second separating part 4 is also beneficial to reduce the contact between the inner wall of the pipe body 1 and the water-containing soil, thereby reducing the adhesion of the water-containing soil on the inner wall of the pipe body 1. In addition, the second separating driving part 42 is configured to drive the second protruding parts 41 to move in the second direction, which is beneficial to form a pore structure in the water-containing soil adhered to the elbow pipe segment 13, thereby further reducing the structural strength of the adhered water-containing soil, and facilitating the separating part 2 to separate and remove the adhered water-containing soil. The second protruding part 41 has the second avoiding state, which is beneficial to avoid interference between the second protruding part 41 and the separating bottom plate 22, to provide sufficient flow space for the suction airflow, and to avoid the cut water-containing soil from falling and adhering to the second protruding part 41 again.

[0103] In some embodiments, the second separating part 4 further comprises a second separating frame 43, and the second protruding parts 41 are arranged on one side of the second separating frame 43 close to the inlet 1A. The second separating driving part 42 is drivingly connected with the second separating frame 43 and is configured to drive the second separating frame 43 to move in the second direction to switch the second protruding parts 41 between the second protruding state and the second avoiding state. This arrangement is beneficial to drive a plurality of second protruding parts 41 to move in the second direction simultaneously by the second separating driving part 42, thereby reducing the number of the second separating driving part 42.

[0104] In some embodiments, the anti-blocking suction pipe further comprises a second containing cavity 15. The second containing cavity 15 is located on the side of the elbow pipe segment 13 away from the first pipe segment 11 and communicates with the elbow pipe segment 13. The inner wall of the second containing cavity 15 forms a second containing space, and the second separating driving part 42 is arranged in the second containing space. This arrangement is beneficial to avoid the second separating driving part 42 from being in contact with the water-containing soil in the suction airflow for a long time, thereby prolonging the service life of the equipment.

[0105] In some embodiments, the second accommodating space has a uniform cross-section along the second direction. The cross-section of the second separation frame 43 perpendicular to the second direction has at least a partially identical shape to the cross-section of the inner wall of the second accommodating cavity 15 perpendicular to the second direction, and slides in engagement with the inner wall of the second accommodating cavity 15. This arrangement is structurally simple, allowing a portion of the surface of the second separation frame 43 to form a moving pair with the inner wall of the second accommodating cavity 15, which facilitates guiding the movement of the second separation frame 43 and prevents it from deviating from the second direction during movement.

[0106] In some embodiments, the second separating portion 4 further includes a baffle 44. The baffle 44 has a plurality of baffle through-holes 44A, and the plurality of second protrusions 41 are provided in a one-to-one correspondence with the plurality of baffle through-holes 44A. The cross-section of the second protrusion 41 perpendicular to the second direction matches the cross-section of the corresponding baffle through-hole 44A perpendicular to the second direction, so that the second protrusion 41 passes through the corresponding baffle through-hole 44A and moves in the second direction.

[0107] The baffle 44 is provided to reduce the contact area between the water-containing soil and the inner wall of the pipe body 1. The second protrusion 41 is provided to move through the baffle through hole 44A, which is beneficial to guide the movement direction of the second protrusion 41 so that the second protrusion 41 does not deviate from the second direction during the switching process.

[0108] The embodiment of the present disclosure further provides a suction vehicle, comprising the anti-blocking suction pipe of the embodiment of the present disclosure.

[0109] The suction vehicle of the disclosed embodiment has the advantages of the anti-blocking suction pipe of the disclosed embodiment.

[0110] The present disclosure also provides an anti-blocking control method, which includes:

[0111] When the curved pipe section 13 is not blocked, the splitter bottom plate 22 of the anti-blocking device is in a reset state. When the curved pipe section 13 is blocked, the splitter drive unit 21 drives the splitter bottom plate 22 of at least one segment 2 from the reset state to the cutting state and then back to the reset state. This method facilitates the timely removal of water-containing soil adhering to the curved pipe section 13 of the anti-blocking suction pipe, thereby ensuring the normal operation of the anti-blocking suction pipe and the suction vehicle.

[0112] In some embodiments, the anti-blocking control method further includes: determining whether the curved pipe section 13 is in a blocked state based on the detection result of the wind pressure detection device. This method is conducive to timely detection of blockage of the curved pipe section 13 and is conducive to realizing automated operation of the anti-blocking suction pipe.

[0113] In some embodiments, the anti-blocking control method further includes: when the curved pipe section 13 is blocked, the controller controls the segmentation drive unit 21 to sequentially drive the segmentation bottom plates 22 of at least two segmentation units 2 from the reset state to the cutting state and then to the reset state, from the side closest to the inlet 1A to the side farther from the inlet 1A. This method facilitates the removal of water-bearing soil with a small accumulation thickness first, thereby improving the efficiency of water-bearing soil removal.

[0114] In some embodiments, the anti-blocking control method further includes: before the dividing base plate 22 switches from the reset state to the cutting state, the first separation drive unit 32 drives the first protrusion 31 to move in the first direction to switch from the first extended state to the first retracted state. This method helps reduce friction during the switching process of the dividing base plate 22, provides sufficient circulation space for the suction airflow, and prevents water-containing soil in the suction airflow that has just entered the anti-blocking suction pipe from adhering to the first protrusion 31.

[0115] In some embodiments, the anti-blocking control method further includes: before the split bottom plate 22 switches from the reset state to the cutting state, the second separation drive unit (42) drives the second protrusion 41 to move in the second direction to switch from the second extended state to the second avoidance state. This method is conducive to forming a gap structure in the water-containing soil adhered to the inner wall of the curved pipe section 13, and is conducive to providing sufficient circulation space for the suction airflow. Driving the second protrusion 41 to switch from the second extended state to the second avoidance state is conducive to preventing the cut water-containing soil from falling and adhering to the second protrusion 41.

[0116] The anti-blocking control method of the embodiment of the present disclosure has the advantages of the anti-blocking suction pipe of the embodiment of the present disclosure.

[0117] The following combination Figures 3 to 12 The anti-blocking suction pipe and the suction vehicle according to the embodiment of the present disclosure are described in detail.

[0118] like Figure 3 As shown, the anti-blocking suction pipe includes a pipe body 1 and an anti-blocking device. The inner walls of the first and second pipe sections 11 and 12 of the anti-blocking suction pipe are circular in cross-section. The first accommodating space formed by the inner wall of the first accommodating cavity 14 and the second accommodating space formed by the inner wall of the second accommodating cavity 15 are both circular in cross-section.

[0119] The anti-blocking device is arranged in the bend section 13, such as Figure 4As shown, the anti-blocking device includes three segments 2: segment I 2-1, segment II 2-2, and segment III 2-3, arranged sequentially from near inlet 1A to far away. Segment I 2-1 includes segment drive I 211, segment base I 221, and guide connector I 231; segment II 2-2 includes segment drive II 212, segment base II 222, and guide connector II 232; and segment III 2-3 includes segment drive III 213, segment base III 223, and guide connector III 233. Each segment drive I 211, II 212, and III 213 is a rod formed by connecting two cylindrical segments of unequal diameters end to end. The smaller cylindrical segment is connected to each guide connector 23 at one end and to the larger cylindrical segment at the other end. The drive element is mounted within the larger cylindrical segment.

[0120] The dividing bottom plates I 221, II 222, and III 223 are connected to form the dividing bottom plates. The cross-section of the dividing bottom plates perpendicular to the first direction is circular and conforms to the cross-section of the inner wall of the first accommodating cavity 14 perpendicular to the first direction. Each dividing bottom plate 22 has a plurality of bottom plate through-holes 22A, which are evenly distributed on the dividing bottom plates. The edges of the dividing bottom plates I 221 and II 222 that are not connected to the inner wall of the tube body 1 have semicircular openings, and two adjacent semicircular openings are spliced ​​together to form a circular bottom plate through-hole 22A. Similarly, the edges of the dividing bottom plates II 222 and III 223 that are not connected to the inner wall of the tube body 1 also have semicircular openings, and two adjacent semicircular openings are spliced ​​together to form a circular bottom plate through-hole 22A.

[0121] Take the segment I2-1 as an example (segment II2-2 and segment III2-3 and so on), Figure 5 As shown, the splitting drive unit I 211 is drivingly connected to the splitting base plate I 221 via a guide connector I 231. The guide connector I 231 is a downward-facing U-shaped structure (having two wings and a middle portion connecting the wings). Both wings of the guide connector I 231 have surfaces that mate with the inner wall of the first accommodating cavity 14. The splitting drive unit I 211 is located within the first accommodating space and is connected to the middle portion of the guide connector I 231 to drive the guide connector I 231 to slide within the first accommodating cavity 14.

[0122] like Figure 8As shown, the first separation portion 3 includes a first separation plate 33, a first separation drive portion 32 and a first protrusion 31. The first separation plate 33 is a circular plate. The first protrusion 31 is a cylinder along the first direction, one end of which is connected to the side of the first separation plate 33 close to the outlet 1B and is arranged in a one-to-one correspondence with the bottom plate through hole 22A. The diameter of the first protrusion 31 is the same as the diameter of the corresponding bottom plate through hole 22A. The first separation drive portion 32 is connected to the side of the first separation plate 33 away from the outlet 1B, and drives the first separation plate 33 to move in the first direction so that the first protrusion 31 switches between the first extended state and the first avoidance state along the first direction. The first protrusion 31 includes multiple rows of short protrusions 311 and two rows of long protrusions 312. The length of the long protrusions 312 is greater than the length of the short protrusions 311, and the long protrusions 312 are arranged corresponding to the circular bottom plate through hole 22A formed by splicing two adjacent semicircular grooves on the dividing bottom plate 22. The length of a row of long protrusions 312 corresponding to the bottom plate through holes 22A on the edge of the divided bottom plate I 221 and the divided bottom plate II 222 is 1 / 4 of the diameter of the inner wall section of the first pipe segment 11; the length of a row of long protrusions 312 corresponding to the bottom plate through holes 22A on the edge of the divided bottom plate II 222 and the divided bottom plate III 223 is 1 / 2 of the diameter of the cross section of the first pipe segment 11.

[0123] like Figure 9 As shown, the first protrusion 31 can move in the first direction through the corresponding bottom plate through hole 22A. The radius of the first separation plate 33 is the same as the curvature radius of the inner wall of each guide connecting member 23 perpendicular to the first direction, and the first separation plate 33 and each guide connecting member 23 are slidably matched. Figure 6 As shown, a hole 23A is formed in the middle portion of the guide connecting member II 232. The first separation driving portion 32 passes through the hole 23A and drives the first separation plate 33 to move in the first direction.

[0124] like Figures 10 to 12As shown, the second separation part 4 includes a second protrusion 41, a second separation drive part 42, a second separation frame 43 and a baffle 44. The second separation frame 43 is a circular plate. The second protrusion 41 is a cylinder along the second direction, one end of which is connected to the side of the second separation frame 43 close to the entrance 1A, and is evenly distributed on the second separation frame 43. The second separation drive part 42 is connected to the side of the second separation frame 43 away from the entrance 1A, and drives the second separation frame 43 to move in the second direction so that the second protrusion 41 switches between the second extended state and the second avoidance state along the second direction. The baffle 44 is a circular plate with the same diameter as the second separation frame 43, and the baffle 44 has a baffle through hole 44A, which is arranged one-to-one with the second protrusion 41. The diameter of the second protrusion 41 is the same as the diameter of the baffle through hole 44A, and the second protrusion 41 can move in the second direction through the corresponding baffle through hole 44A. The cross sections of the second separation frame 43 and the baffle 44 perpendicular to the second direction are consistent with the cross sections of the inner wall of the second accommodating cavity 15 perpendicular to the second direction, and are slidably fitted with the inner wall of the second accommodating cavity 15 .

[0125] like Figure 3 As shown, a first wind pressure sensor 51 is mounted on the first pipe section 11 to detect the wind pressure at the inlet 1A, and a second wind pressure sensor 52 is mounted on the second pipe section 12 to detect the wind pressure at the outlet 1B. A controller (not shown) is signal-connected to the first and second wind pressure sensors 51, 52, and the splitting drive unit 21. The controller controls the splitting drive unit 21 to switch the splitting base plate 22 between the reset state and the cutting state based on the first wind pressure difference.

[0126] The following describes in detail the anti-blocking control method for the anti-blocking suction pipe applied to the above embodiment:

[0127] When it is detected that the difference between the second wind pressure sensor 52 and the first wind pressure sensor 51 is greater than the first wind pressure difference, it is determined that the curved pipe section 13 is in a blocked state.

[0128] When the bend section 13 is not in a blocked state, the dividing bottom plate 22 of the anti-blocking device is in a reset state, the first protrusion 31 of the first separation portion 3 is in a first extended state, and the second protrusion 411 of the second separation portion 4 is in a second extended state (such as Figure 3 ).

[0129] When the bend section 13 is in a blocked state, first, the first separation drive unit 32 drives the first separation plate 33 to switch from the first extended state to the first avoidance state in the first direction; at the same time, the second separation drive unit 42 drives the second separation frame 41 to switch from the second extended state to the second avoidance state in the second direction; then, the controller controls the splitting drive unit I211, the splitting drive unit II212 and the splitting drive unit III213 to drive the splitting bottom plate I221, the splitting bottom plate II222 and the splitting bottom plate III223 in turn from the reset state to the cutting state and then to the reset state; finally, the first separation drive unit 32 drives the first separation plate 33 to switch from the first avoidance state back to the first extended state; at the same time, the second separation drive unit 42 drives the second separation frame to switch from the second avoidance state back to the second extended state in the second direction.

[0130] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not intended to limit them. Although the present disclosure has been described in detail with reference to preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present disclosure can still be modified or some technical features can be replaced by equivalents, which should all be included in the scope of the technical solutions claimed for protection in the present disclosure.
