[0002] Pipeline unblocking devices, especially small and medium diameter pipelines, are usually used in liquid or gas conveying systems in various fields. Whether it is industrial production, medical treatment, medicine, or food processing industry, etc., small and medium diameter pipelines are almost needed to convey liquid or gas. However, after a long time of use, some dirt, deposits, biomass, and other attachments will be deposited on the inner wall of the pipeline, which will seriously affect the transmission efficiency and service life of the pipeline. At present, the dredging construction of small and medium diameter pipelines mainly adopts manual holding of related equipment into the pipeline for construction operation. For the construction personnel, the environment inside the pipeline is very poor, and the working environment inside is relatively poor, which increases the construction difficulty; some harmful substances in the pipeline are harmful to the human body under the disturbance of air flow, and there is a certain safety risk; in terms of cleaning efficiency, the traditional construction needs to arrange corresponding rest time each time, and the quality of manual holding equipment unblocking is not the same, and some very firm blockages cannot be cleaned.

According to the advancing direction of the dredging and dredging device, the front protection mechanism 100 is placed into the pipeline, after the front protection mechanism 100 is placed into the pipeline for a certain distance, the parallel mechanism 200, the flexible sleeve 700 and the corresponding line are installed at the rear end of the front protection mechanism 100, after the installation is completed, continue to be placed into the pipeline, until the front protection mechanism 100 completely enters the pipeline; after the front protection mechanism 100 enters the pipeline, the rear protection mechanism 100 is connected to the rear parallel mechanism 200 and the flexible sleeve 700 of the front protection mechanism 100, after the installation is completed, the rear protection mechanism 100 is placed into the pipeline, until the whole dredging and dredging device enters the pipeline; the corresponding pipeline in the dredging and dredging device is connected to the external control terminal 900, to complete the installation of the whole device.

[0068] When the dredging and dredging device enters the pipeline, the running state information of the dredging and dredging device in the pipeline is acquired in real time and is fed back to the control terminal 900 to judge whether the device has fault information, so as to avoid low work efficiency caused by failure in the working process. If the device has fault information, the control terminal 900 sends the execution instruction of the fault mode to the dredging and dredging device in the pipeline, so that the dredging and dredging device executes the fault mode to complete the recycling work of the whole.

[0069] S1, the dredging and dredging device acquires the pipeline feature and calculates the distance between the dredging and dredging device and the dredging area, generates the work information, and the work information includes the pipeline environment information and the distance information of the dredging area.

[0070] In the embodiment, specifically, when the dredging and unblocking device enters the pipeline, the sensing mechanism 1000 installed at the front end of the front protection mechanism 100 is used to scan and obtain the pipeline topographic features and the distance between the dredging and unblocking device and the unblocked region, so as to generate the operation information, which includes the pipeline environment information and the distance information of the unblocked region. The pipeline environment information is the shape (straight or curved) of the pipeline, and also includes the pipeline environment of the unblocked region. The distance information is the distance required by the current dredging and unblocking device from the blockage of the unblocked region. The operation information is obtained in advance, so that the dredging and unblocking device can move according to the specific mode according to the specific information obtained, so as to improve the efficiency of construction and the high-precision control of the device.

[0071] S2, the generated operation information is transmitted to the control terminal 900. The control terminal 900 matches the received operation information with the pre-stored movement mode to determine the movement mode of the dredging and unblocking device. The movement mode includes the operation movement mode and the rapid movement mode.

[0072] In the embodiment, specifically, the scanned and generated operation information is transmitted to the external control terminal 900. The control terminal 900 pre-stores the related information of multiple movement modes. The control terminal 900 matches the received operation information with the matching algorithm to obtain the most matched movement mode under the current operation information, so that the dredging and unblocking device moves to the unblocked region according to the mode. The embodiment matches and selects the most suitable movement mode of the dredging and unblocking device under the current state according to the obtained operation information, so as to improve the efficiency of construction.

[0073] S3, when the control terminal 900 determines the movement mode of the dredging and unblocking device, the control terminal 900 sends the execution instruction corresponding to the movement mode to the dredging and unblocking device. The dredging and unblocking device moves to the unblocked region according to the received execution instruction.

[0074] In the embodiment, specifically, when the control terminal 900 determines the movement mode of the dredging and unblocking device (operation movement mode or rapid movement), the control terminal 900 sends the execution instruction corresponding to the operation movement mode or the rapid movement mode to the dredging and unblocking device. The dredging and unblocking device moves to the unblocked region according to the received execution instruction. By determining the execution mode of the dredging and unblocking device, the dredging and unblocking device moves to the unblocked region according to the execution mode, so as to improve the efficiency during construction.

[0075] S4, when the dredging and dredging equipment moves to the set distance of the dredging area, feedback to the control terminal 900, the control terminal 900 sends the execution instruction of support operation mode to the dredging and dredging equipment according to the received feedback information, and the dredging and dredging equipment performs corresponding action according to the received execution instruction to dredging operation in the dredging area.

[0076] In this embodiment, specifically: when the dredging and dredging equipment moves to the set distance of the dredging area, the front end of the protection mechanism 100 of the front section acquires the current information and feedback to the control terminal 900; when the control terminal 900 receives the information, it sends the execution instruction of support operation mode to the dredging and dredging equipment, and the dredging and dredging equipment performs the related action of support operation mode according to the received execution instruction to dredging operation in the dredging area.

[0077] And the support operation mode is specifically:

[0078] The support mechanism 300 on the front section of the protection mechanism 100 and the rear section of the protection mechanism 100 is ejected, and the front section and the rear section of the protection mechanism 100 is supported and fixed. First, the hydraulic system 600 sends hydraulic oil to the first hydraulic cylinder 333 through the hydraulic pipeline to control the retraction of the first hydraulic cylinder 333. Since one end of the first connecting rod 331 and the second connecting rod 332 is connected with the inner side wall of the protection mechanism 100 through the connecting seat 334, the first hydraulic cylinder 333 will drive the second connecting rod 332 to swing in the forward direction of the whole device. Since the first connecting rod 331 and the second connecting rod 332 are fixedly connected with the support mounting plate 320, when the second connecting rod 332 swings in the forward direction, it will drive the first connecting rod 331 to swing in the forward direction of the whole device through the support mounting plate 320. When the first connecting rod 331 and the second connecting rod 332 swing in the forward direction of the whole device, the support mounting plate 320 is tilted and ejected upward, thereby driving the support body 310 to be ejected in the direction outside the limiting groove of the protection mechanism 100. The first hydraulic cylinder 333 provides a fixing force for the support body 310 to be fixed, so as to complete the support and fixation of the front section and the rear section of the protection mechanism 100.

[0079] When the support mechanism 300 completes the support and fixation of the protection mechanism 100 of the front section and the rear section, the water jet mechanism 400 at the front end of the protection mechanism 100 of the front section adjusts the jet position of the water jet according to the specific position of the blockage, including the circumferential rotation adjustment of the overall water jet mechanism 400 by the rotating mechanism 500, and the radial movement adjustment of the water jet mechanism 400 itself. When the jet position of the water jet is adjusted in the circumferential rotation, the hydraulic system 600 delivers hydraulic oil to the drive motor 510 through the hydraulic pipeline and controls the drive motor 510, the drive motor 510 drives the driving gear 520 to rotate, the driven gear ring 530 is engaged with the driving gear 520 to rotate, the first cover 410 is driven by the driven gear ring 530 to rotate circumferentially, so that the second cover 420 and the jet head 430 and the adjusting assembly 440 in the second cover 420 follow the circumferential rotation, to complete the circumferential rotation adjustment of the jet position of the water jet. When the jet position of the water jet is adjusted in the radial movement by the water jet mechanism 400 itself, the second hydraulic cylinder 442 drives the jet head 430 to slide on the linear slide rail 441 to adjust the position of the jet head 430 on the rectangular water outlet 421, to complete the radial movement adjustment of the jet position of the water jet. Through the cooperation between the rotating mechanism 500 and the adjusting assembly 440, the jet position of the water jet is accurately adjusted, the blockage can be cleaned and dredged according to the specific position of the blockage, and the dredging work of the to-be-dredged area is completed.

[0080] In one of the embodiments, the distance information includes long distance and short distance; in step S2, the following steps are specifically included:

[0081] S21, the control terminal 900 analyzes and confirms the distance between the dredging and dredging equipment and the to-be-dredged area according to the received work information, and selects the movement mode of the dredging and dredging equipment according to the determined distance;

[0082] S211, if the distance between the dredging and dredging equipment and the to-be-dredged area is a long distance, the control terminal 900 sends an execution instruction corresponding to the fast movement mode to the dredging and dredging equipment, and the dredging and dredging equipment moves to the to-be-dredged area according to the received execution instruction in the fast movement mode;

[0083] S212, if the distance between the dredging and dredging equipment and the to-be-dredged area is a short distance, the control terminal 900 sends an execution instruction corresponding to the work movement mode to the dredging and dredging equipment, and the dredging and dredging equipment moves to the to-be-dredged area according to the received execution instruction in the work movement mode.

[0084] In the embodiment, the control terminal 900 analyzes and confirms the distance between the dredging and cleaning equipment and the region to be dredged and cleaned according to the distance information obtained by the sensing mechanism 1000, so as to select the moving mode corresponding to the dredging and cleaning equipment according to long distance or short distance. If it is long distance, the fast moving mode is selected, and if it is short distance, the working moving mode is selected.

[0085] In one of the embodiments, the pipeline environment information includes straight pipeline environment and curved pipeline environment, the working moving mode includes straight walking mode and peristaltic turning mode, and the fast moving mode includes wheel train straight walking mode and wheel train peristaltic turning mode.

[0086] After the step S21, the following steps are further included:

[0087] S22, the control terminal 900 further analyzes and confirms the pipeline environment according to the received working information based on the determined moving mode, so as to further select the moving mode of the dredging and cleaning equipment according to the determined pipeline environment;

[0088] S221, if the determined pipeline environment is straight pipeline environment, the control terminal 900 sends the execution instruction corresponding to the straight walking mode or the wheel train straight walking mode to the dredging and cleaning equipment, and the dredging and cleaning equipment moves to the region to be dredged and cleaned according to the straight walking mode or the wheel train straight walking mode according to the received execution instruction;

[0089] S222, if the determined pipeline environment is curved pipeline environment, the control terminal 900 sends the execution instruction corresponding to the peristaltic turning mode or the wheel train peristaltic turning mode to the dredging and cleaning equipment, and the dredging and cleaning equipment moves to the region to be dredged and cleaned according to the peristaltic turning mode or the wheel train peristaltic turning mode according to the received execution instruction.

[0090] In the embodiment, since the obtained pipeline environment information includes straight pipeline environment and curved pipeline environment, when the dredging and cleaning equipment executes the working moving mode or the fast moving mode, the corresponding moving mode (straight walking mode or wheel train straight walking mode, peristaltic turning mode or wheel train peristaltic turning mode) needs to be further selected according to the pipeline environment, so as to improve the construction efficiency. If part of the obtained pipeline environment information is straight pipeline environment, and the region to be dredged and cleaned is curved pipeline environment, the dredging and cleaning equipment is controlled to move according to the straight walking mode or the wheel train straight walking mode in the straight pipeline environment, and the dredging and cleaning equipment is controlled to move according to the peristaltic turning mode or the wheel train peristaltic turning mode in the curved pipeline environment.

[0091] In one of the embodiments, when the dredging and dredging equipment moves to the dredging area according to the received execution instruction, the control terminal 900 transmits the execution instruction to the hydraulic system 600, the hydraulic system 600 receives the execution instruction and controls the extension and retraction of the support mechanism 300 of the front protection mechanism 100, the synchronous extension and retraction of the parallel mechanism 200 and the extension and retraction of the support mechanism 300 of the rear protection mechanism 100 in sequence to complete the straight line walking of the dredging and dredging equipment.

[0092] In this embodiment, when the dredging and dredging equipment is executed according to the straight line walking mode in step S221, specifically:

[0093] The straight line walking of the dredging and dredging equipment is realized by the cooperation between the support mechanism 300, the parallel mechanism 200 on the front protection mechanism 100 and the support mechanism 300 on the rear protection mechanism 100. The hydraulic system 600 provides hydraulic oil to the support mechanism 300 and the parallel mechanism 200 through the hydraulic pipeline, and controls the retraction of the support mechanism 300 of the front protection mechanism 100, the extension of the support mechanism 300 of the rear protection mechanism 100, the synchronous extension of each hydraulic cylinder group of the parallel mechanism 200 in sequence. After the front protection mechanism 100 reaches the predetermined position, the support mechanism 300 is extended and fixed, the support mechanism 300 of the rear protection mechanism 100 is retracted, and each hydraulic cylinder group of the parallel mechanism 200 is retracted synchronously, so that the dredging and dredging equipment advances forward in the form of peristalsis, completes the straight line walking action, and the cycle is repeated until the whole pipeline dredging and dredging equipment reaches the specified construction station of the dredging area.

[0094] The extension and retraction of the support mechanism 300 and the synchronous extension and retraction of the parallel mechanism 200 are as follows:

[0095] The extension of the support mechanism 300 is that the hydraulic system 600 delivers hydraulic oil to the first hydraulic cylinder 333 of the support mechanism 300 on the front protection mechanism 100 through the hydraulic pipeline to control the retraction of the extension end of the first hydraulic cylinder 333. Since one end of the first connecting rod 331 and the second connecting rod 332 is rotatably connected to the inner side wall of the protection mechanism 100 through the connecting seat 334, the first hydraulic cylinder 333 will drive the second connecting rod 332 to swing in the forward direction of the whole equipment. Since the first connecting rod 331 and the second connecting rod 332 are fixedly connected to the support mounting plate 320, when the second connecting rod 332 swings in the forward direction, it will drive the first connecting rod 331 to swing in the forward direction of the whole equipment through the support mounting plate 320. When the first connecting rod 331 and the second connecting rod 332 swing in the forward direction of the whole equipment, the support mounting plate 320 is tilted and pushed out upward, thereby driving the support body 310 to be pushed out to the outside of the limiting groove of the protection mechanism 100. The retraction is the same.

[0096] Synchronous ejection of parallel mechanism 200: hydraulic system 600 simultaneously delivers hydraulic oil to six independent third hydraulic cylinders 230 through hydraulic pipelines to control third hydraulic cylinders 230 to synchronously eject towards the advancing direction of the dredging and unblocking device, so that the front section protection mechanism 100 moves towards the advancing direction of the dredging and unblocking device. The retraction is the same.

[0097] In one embodiment, when the dredging and unblocking device moves to the area to be dredged according to the received execution instruction in the wheel train straight line walking mode, the control terminal 900 transmits the execution instruction to the hydraulic system 600, and the hydraulic system 600 receives the execution instruction and controls the front section protection mechanism 100 and the rear section protection mechanism 100 on the support mechanism 300 to retract, and drives the walking mechanism 800 on the front section protection mechanism 100 and the rear section protection mechanism 100 to rotate towards the advancing direction, so as to complete the wheel train straight line walking of the dredging and unblocking device.

[0098] In this embodiment, when the dredging and unblocking device is executed in the wheel train straight line walking mode in step S221, specifically:

[0099] The support mechanism 300 on the front section protection mechanism 100 and the support mechanism 300 on the rear section protection mechanism 100 retract at the same time, and the walking mechanism 800 on the front section protection mechanism 100 and the walking mechanism 800 on the rear section protection mechanism 100 drive the front section protection mechanism 100 and the rear section protection mechanism 100 to move at the same time, so as to realize the whole device to complete the wheel train straight line walking of the dredging and unblocking device. The hydraulic system 600 provides hydraulic oil to the support mechanism 300 and the walking mechanism 800 through the hydraulic pipeline, and controls the support mechanism 300 on the front section protection mechanism 100 and the rear section protection mechanism 100 to retract at the same time, and the support mechanism 300 retraction principle is the same as above; and controls the walking mechanism 800 on the front section protection mechanism 100 and the rear section protection mechanism 100 to rotate towards the advancing direction of the dredging and unblocking device, until the whole pipeline dredging and unblocking device reaches the designated construction station of the area to be dredged, so as to complete the wheel train straight line walking of the dredging and unblocking device.

[0100] In one embodiment, when the dredging and unblocking device moves to the area to be dredged according to the received execution instruction in the peristaltic turning mode, the control terminal 900 transmits the execution instruction to the hydraulic system 600, and the hydraulic system 600 receives the execution instruction and controls the support mechanism 300 of the front section protection mechanism 100 in the advancing direction of the dredging and unblocking device to extend and retract, the parallel mechanism 200 to extend and retract asynchronously, and the support mechanism 300 of the rear section protection mechanism 100 to extend and retract, so as to complete the turning walking of the dredging and unblocking device.

[0101] In the embodiment, when the dredging and unblocking device is executed according to the peristaltic turning mode in step S222, specifically:

[0102] The turning walking of the whole device is realized by the cooperation among the support mechanism 300 on the front protection mechanism 100, the parallel mechanism 200 and the support mechanism 300 on the rear protection mechanism 100. The hydraulic system 600 provides hydraulic oil to the support mechanism 300 and the parallel mechanism 200 through the hydraulic pipeline, and controls the support mechanism 300 on the front protection mechanism 100 to retract, controls the support mechanism 300 on the rear protection mechanism 100 to extend, controls the non-synchronous extension of each hydraulic cylinder group of the parallel mechanism 200 in turn (the extension order is selected according to the actual curvature range of the pipeline), the support mechanism 300 on the front protection mechanism 100 extends and fixes when the front protection mechanism 100 reaches the predetermined position, the support mechanism 300 on the rear protection mechanism 100 retracts, and each hydraulic cylinder group of the parallel mechanism 200 is non-synchronously retracted in turn, so that the dredging and unblocking device advances in a peristaltic manner, and the turning advancing action is completed. The support mechanism 300 cooperates with the non-synchronous extension and retraction of the parallel mechanism 200 to make the device smoothly pass through the curved pipeline with a certain curvature range. The extension and retraction of the support mechanism 300 and the synchronous extension and retraction of the parallel mechanism 200 are the same as above.

[0103] In one of the embodiments, when the dredging and unblocking device moves to the unblocked area according to the received execution instruction, the control terminal 900 transmits the execution instruction to the hydraulic system 600, the hydraulic system 600 receives the execution instruction and controls the support mechanism 300 on the front protection mechanism 100 and the rear protection mechanism 100 of the advancing direction to retract, and drives the walking mechanism 800 on the front protection mechanism 100 and the rear protection mechanism 100 to turn towards the advancing direction and controls the non-synchronous extension and retraction of the parallel mechanism 200, so as to complete the wheel train turning walking of the dredging and unblocking device.

[0104] In the embodiment, when the dredging and unblocking device is executed according to the peristaltic turning mode in step S222, specifically:

[0105] The support mechanism 300 on the front section of the protection mechanism 100 and the support mechanism 300 on the rear section of the protection mechanism 100 are simultaneously retracted, the walking mechanism 800 on the front section of the protection mechanism 100 and the walking mechanism 800 on the rear section of the protection mechanism 100 are simultaneously driven to move the front section of the protection mechanism 100 and the rear section of the protection mechanism 100, and each hydraulic cylinder group of the parallel mechanism 200 is sequentially pushed out in an asynchronous manner, so as to realize the turning walking of the overall device by the dredging and unblocking device. The hydraulic system 600 provides hydraulic oil to the support mechanism 300 and the walking mechanism 800 through the hydraulic pipeline, and sequentially controls the support mechanism 300 on the front section of the protection mechanism 100 and the support mechanism 300 on the rear section of the protection mechanism 100 to be retracted at the same time. The retraction principle of the support mechanism 300 is the same as above; and the walking mechanism 800 on the front section of the protection mechanism 100 and the walking mechanism 800 on the rear section of the protection mechanism 100 are controlled to rotate towards the advancing direction of the dredging and unblocking device, and each hydraulic cylinder group of the parallel mechanism 200 is sequentially pushed out in an asynchronous manner (the pushing out sequence is selected according to the actual curvature range of the pipeline), until the overall pipeline dredging and unblocking device reaches the designated construction station of the unblocked area. The walking mechanism 800 cooperates with the asynchronous extension and retraction of the parallel mechanism 200 to make the device smoothly pass through the curved pipeline with a certain curvature range, so as to realize the turning walking of the overall device.

[0106] In one embodiment, when the dredging and unblocking device executes the fault mode recovery according to the received execution instruction, the control terminal 900 transmits the execution instruction to the hydraulic system 600, and the hydraulic system 600 receives the execution instruction and controls the support mechanism 300 on the protection mechanism 100 to be retracted and controls the walking mechanism 800 on the protection mechanism 100 to drive the dredging and unblocking device to complete the overall recovery work.

[0107] In this embodiment, when the dredging and unblocking device executes the fault mode according to step S03, specifically:

[0108] The hydraulic system 600 is depressurized to make the support mechanism 300 on the front section of the protection mechanism 100 and the rear section of the protection mechanism 100 retract, and the independent hydraulic motor drives the walking mechanism 800 to make the walking mechanism 800 drive the overall device to retreat. If it is at a curved pipe, the walking mechanism 800 cooperates with the asynchronous extension and retraction of the parallel mechanism 200 to make the device smoothly pass through the curved pipeline with a certain curvature range, so that the overall device retreats, so as to avoid low work efficiency caused by failure during operation.

[0109] According to the needs, step S3 further includes:

[0110] S31, the dredging and dredging equipment moves to the area to be dredged according to the received execution instruction, continuously acquires pipeline environment information and sends it to the control terminal 900, and the control terminal 900 judges whether the movement mode of the dredging and dredging equipment needs to be switched according to the received pipeline environment information.

[0111] In this embodiment, the dredging and dredging equipment moves to the area to be dredged in a straight line walking mode, for example, according to the received pipeline environment information to judge whether the peristaltic turning mode, wheel train straight line walking mode or wheel train peristaltic turning mode needs to be switched. The switching condition is that when the dredging and dredging equipment moves to the area to be dredged in a straight line walking mode and completes the dredging work, the pipeline environment information of the next area to be dredged is acquired, when the real-time acquired environment information of the area to be dredged changes to a curved pipe, the peristaltic turning mode is switched; when the real-time acquired environment information of the area to be dredged changes to a long distance, the wheel train straight line walking mode is switched, and when it is a curved pipe, the wheel train peristaltic turning mode is switched. By acquiring the pipeline environment information in real time, and switching the movement mode of the dredging and dredging equipment according to the specific situation, the working efficiency is improved.
