It should be noted that, the supporting mechanisms 300 mounted on the side walls of the protection mechanism 100 connected in a chain structure are identical in structure; when the protection mechanisms 100 are in the double number, taking two as an example, in the advancing process of the integral pipeline dredging device, taking the parallel mechanism 200 in the middle as a distinguishing point to divide the whole into a front section and a rear section, sequentially carrying out shrinkage and extension on the support mechanism 300 on the protection mechanism 100 positioned at the front section in the advancing direction and the support mechanism 300 on the protection mechanism 100 positioned at the rear section in the advancing direction, ejecting the parallel mechanism 200 in the advancing direction, stretching and fixing the support mechanism 300 after the front section protection mechanism 100 reaches a preset position, retracting the support mechanism 300 of the rear section protection mechanism 100, retracting the parallel mechanism 200, completing the advancing action, and carrying out sequential linkage operation among the support mechanism 300 positioned on the protection mechanism 100 positioned at the front section in the advancing direction and the parallel mechanism 200, so that the integral pipeline dredging device is pushed forward to reach a construction position in a peristaltic mode, and simultaneously realizing turning and twisting actions of the integral device through cooperation among the three components; the backward movement is the same. When the protection mechanisms 100 are in the singular, taking three as examples, in the advancing process of the integral pipeline dredging equipment, the distinguishing points of the front section and the rear section are adjusted according to the required advancing speed, when the required advancing speed is slightly higher, the number of the protection mechanisms 100 of the front section is one, the number of the protection mechanisms 100 of the rear section is two, and the advancing and the retreating actions are the same; when the required forward speed is slightly slow, the number of the protection mechanisms 100 at the front section is two, the number of the protection mechanisms 100 at the rear section is one, the parallel mechanism 200 between the protection mechanisms 100 at the front section does not move in the forward process, and the forward and backward actions are the same as the above; the advancing speed is regulated by regulating the distinguishing point of the front section and the rear section of the integral pipeline dredging equipment.

The working principle of the embodiment is as follows: when the integral pipeline dredging equipment advances, hydraulic system 600 provides hydraulic oil for supporting mechanism 300 and parallel mechanism 200 through hydraulic pipeline, and sequentially controls the supporting mechanism 300 of the front-stage protecting mechanism 100 to retract, controls the supporting mechanism 300 of the rear-stage protecting mechanism 100 to extend, controls each hydraulic cylinder group of parallel mechanism 200 to synchronously eject, and controls the supporting mechanism 300 to extend and fix after the front-stage protecting mechanism 100 reaches a preset position, the supporting mechanism 300 of the rear-stage protecting mechanism 100 retracts, and each hydraulic cylinder group of parallel mechanism 200 synchronously contracts to complete the advancing action, so that the cycle is performed until the integral pipeline dredging equipment reaches a specified construction position; when the whole pipeline dredging equipment reaches a designated construction position, the supporting mechanism 300 of the front-stage protection mechanism 100 and the supporting mechanism 300 of the rear-stage protection mechanism 100 are both extended and fixed, so that the whole equipment is fixedly supported, hydraulic oil is provided for the rotating mechanism 500 through a hydraulic pipeline by a control system, the rotating mechanism 500 is controlled to be started, the water jet mechanism 400 is enabled to rotate to adjust a proper jet position of high-pressure water flow, and blockages in the pipeline are cleaned and dredged; when the construction is completed, hydraulic oil is supplied to the supporting mechanism 300 and the parallel mechanism 200 through the hydraulic system 600, and the whole pipeline dredging device is controlled to retreat, and the retreating action is the same as that described above.

In one embodiment, the hydraulic driving assembly 330 includes a first connecting rod 331, a second connecting rod 332, and a first hydraulic cylinder 333;

The extending action of the supporting mechanism 300 is as follows: the hydraulic system 600 is used for conveying hydraulic oil to the first hydraulic cylinder 333 through a hydraulic pipeline to control the telescopic end of the first hydraulic cylinder 333 to retract, because one ends of the first connecting rod 331 and the second connecting rod 332 are rotationally connected with the inner side wall of the protection mechanism 100 through the connecting seat 334, the first hydraulic cylinder 333 can drive the second connecting rod 332 to swing towards the advancing direction of the whole equipment, because 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 towards the advancing direction, the first connecting rod 331 is driven to swing towards the advancing direction of the whole equipment through the support mounting plate 320, after the first connecting rod 331 and the second connecting rod 332 swing towards the advancing direction of the whole equipment, the support mounting plate 320 is driven to tilt upwards, so that the support body 310 is driven to push out towards the outer side direction of the protection mechanism 100, and a fixing force is provided for the support body 310 through the first hydraulic cylinder 333 to fix.

When the whole pipeline dredging device performs a retreating action, the supporting mechanism 300 of the protection mechanism 100 positioned at the front section performs an extending action, and the supporting mechanism 300 of the protection mechanism 100 positioned at the rear section performs a retracting action, and the specific extending and retracting actions are the same as above.

In this embodiment, the first connecting rod 331, the second connecting rod 332 and the first hydraulic cylinder 333 are adopted to cooperate with the support mounting plate 320 and the support body 310, so that the whole support mechanism 300 is in a working mode similar to a link mechanism, and when the whole support mechanism advances or retreats, a fixed thrust is provided by the first hydraulic cylinder 333, so that the whole support mechanism has a fixed supporting force.

When the integral pipeline dredging equipment reaches a construction position to work, the blockage in the pipeline is cleaned and dredged through the water jet mechanism; because the recoil generated by the front water jet mechanism 400 during operation is up to 2000N, i.e., about 200 kg, the first hydraulic cylinder 333 provides a fixed thrust to the first connecting rod 331, the second connecting rod 332, the support mounting plate 320 and the support body 310 to overcome the recoil generated by the water jet mechanism 400, so as to maintain the normal operation of the whole equipment.
