Abstract
Description
Technical Field
[0001] This invention belongs to the field of pipeline cleaning technology, specifically relating to a peristaltic high-pressure water jet pipeline dredging and unblocking device. Background Technology
[0002] Urban drainage is an indispensable and crucial infrastructure for modern cities, exerting a comprehensive and leading influence on urban economic development. It is also a backbone project for urban water pollution control, drainage, flood control, and flood prevention. With economic development and the continuous accumulation of urban population, the drainage pressure on urban drainage systems is increasing daily, while the construction and renovation of municipal sewer systems are far from meeting the demand. Problems in the urban drainage sector are becoming increasingly prominent. Poor drainage can, at best, affect residents' daily lives, and at worst, disrupt the normal rhythm of the entire city. Urban drainage facilities are not only a vital prerequisite for maintaining the city's ecological metabolic functions but also an important measure for protecting urban water resources and the living environment.
[0003] Currently, pipeline cleaning robots on the domestic market are mainly divided into four categories: wheeled, crawler, and tracked. However, there are various ways to connect pipelines. Common pipeline connection methods on the market include pipe bending connections and splicing of pipes with different diameters. Traditional wheeled and tracked pipeline cleaning robots have greatly limited attachment and movement at pipe connections and vertical locations, and may even fall off. Therefore, existing cleaning robots are not ideal for connecting pipes of different diameters or adapting to changes in pipe diameter. This may cause the robot itself to get stuck, damage the pipeline, and become a secondary blockage, resulting in low work efficiency and unsatisfactory cleaning effect. Summary of the Invention

[0050] like Figures 1-6As shown, one embodiment of the present invention provides a peristaltic high-pressure water jet pipeline dredging and unblocking device, comprising:
[0051] At least two protective mechanisms 100, which are connected in a single chain by a parallel mechanism 200 to form a chain structure;
[0052] Support mechanism 300, wherein multiple support mechanisms 300 are arranged in a circumferential array on the side wall of protective mechanism 100;
[0053] A water jet mechanism 400 is installed at the front end of the protective mechanism 100 in the forward direction, and is rotatably connected to the protective mechanism 100 via a rotating mechanism 500 to adjust the spray position of the water jet.
[0054] Hydraulic system 600 is installed inside the protective mechanism 100 and is connected to the parallel mechanism 200, the support mechanism 300 and the rotating mechanism 500 through hydraulic pipelines;
[0055] The support mechanism 300 includes a support body 310, a support mounting plate 320, and a hydraulic drive assembly 330.
[0056] One end of the support 310 is located outside the protective mechanism 100, and the other end is located inside the protective mechanism 100; the support mounting plate 320 and the hydraulic drive assembly 330 are both located inside the protective mechanism 100.
[0057] The support mounting plate 320 is fixedly connected to one end of the support body 310 located inside the protective mechanism 100; one end of the hydraulic drive assembly 330 is fixedly connected to the inner wall of the protective mechanism 100, and the other end is hinged to the support mounting plate 320. The hydraulic drive assembly 330 drives the support body 310 to swing and extend through the support mounting plate 320.
[0058] In this embodiment, the device employs a parallel mechanism 200 to connect the protective mechanism 100 in a single chain to form a chain structure, and a support mechanism 300 is arranged in a circumferential array on the side wall of the protective mechanism 100. Through the cooperation of the support mechanism 300 and the protective mechanism 100, the device completes the peristaltic forward, turning and rotating actions in the pipeline, thereby adapting to different pipelines. By setting a water jet mechanism 400 at the front end of the protective mechanism 100 in the forward direction, the blockage in the pipeline can be cleared and dredged during the forward movement. The water jet mechanism 400 is rotatably connected to the protective mechanism 100 through a rotating mechanism 500, and can be adjusted to clear and dredge blockages at specific locations.
[0059] Specifically, refer to Figure 1The pipeline dredging and unblocking equipment consists of at least two cylindrical protective mechanisms 100 connected in a single-chain configuration via a parallel mechanism 200 to form a chain structure. The specific number of protective mechanisms 100 is determined based on actual usage. At least three support mechanisms 300 are arranged in a circular array along the center circumference of each protective mechanism 100 on its sidewall to support it during operation. These support mechanisms 300, in conjunction with the parallel mechanism 200, enable the equipment to move forward, turn, and rotate during operation, allowing it to adapt to different pipeline conditions. A water jet mechanism 400 is located at the front end of the protective mechanism 100 in its forward direction to clear blockages in the pipeline, clearing blockages while moving. A rotating mechanism 500 is located at the connection between the water jet mechanism 400 and the protective mechanism 100, driving the water jet mechanism 400 and the protective mechanism 100 to rotate coaxially, thereby adjusting the high-pressure water flow of the water jet mechanism 400. The spray position allows the water jet mechanism 400 to complete specific and designated construction positions when clearing and unblocking blockages in the pipeline. A hydraulic system 600 is installed inside the protective mechanism 100, which is generally located at the end of the chain-like structure of the protective mechanism 100. The hydraulic system 600 is connected to the parallel mechanism 200, the support mechanism 300, and the rotating mechanism 500 via hydraulic pipes. It provides hydraulic oil to the parallel mechanism 200, the support mechanism 300, and the rotating mechanism 500 and controls them to perform corresponding construction actions. For example, the hydraulic system 600 controls the extension and retraction of the parallel mechanism 200, causing the protective mechanism 100 to move forward or backward; it controls the extension and retraction of the support mechanism 300; and it controls the start of the rotating mechanism 500, causing the water jet mechanism 400 to rotate and adjust the spray position of the high-pressure water flow.
[0060] Furthermore, referring to Figure 2 , Figure 3The support mechanism 300 includes a support body 310, a support mounting plate 320, and a hydraulic drive assembly 330. One end of the support body 310 is located outside the protective mechanism 100, and the other end is located inside the protective mechanism 100. The end located inside the protective mechanism 100 is fixedly connected to the support mounting plate 320. One end of the hydraulic drive assembly 330 is fixedly connected to the inner wall of the protective mechanism 100, and the other end is fixedly connected to the support mounting plate 320. The hydraulic system 600 is connected to the hydraulic drive assembly 330 through hydraulic pipes and is used to provide hydraulic oil to the hydraulic drive assembly 330 and control the hydraulic drive assembly 330 to perform corresponding actions. The hydraulic drive assembly 330 drives the support body 310 to swing and extend. Correspondingly, the side wall of the protective mechanism 100 has a limiting groove corresponding to the maximum swing amplitude of the support body 310 to ensure that the support body 310 can swing normally.
[0061] It should be noted that the support mechanisms 300 installed on the side walls of the chain-connected protective mechanisms 100 all have the same structure. When there are an even number of protective mechanisms 100, taking two as an example, during the forward movement of the overall pipeline dredging and clearing equipment, the entire system is divided into a front section and a rear section using the parallel mechanism 200 located in the middle as a dividing point. After the support mechanisms 300 on the protective mechanism 100 in the front section and the support mechanisms 300 on the protective mechanism 100 in the rear section in the forward direction retract and extend in sequence, the parallel mechanism 200 pushes out in the forward direction, and the front section protective mechanism 100... After reaching the predetermined position, the support mechanism 300 extends and is fixed, the support mechanism 300 of the rear protection mechanism 100 retracts, and the parallel mechanism 200 retracts, completing the forward movement. The support mechanism 300 on the front section of the protection mechanism 100 in the forward direction, the support mechanism 300 on the rear section of the protection mechanism 100 in the forward direction, and the parallel mechanism 200 operate in sequence, so that the entire pipeline dredging and clearing equipment moves forward in a creeping manner to the construction position. At the same time, the turning and twisting movements of the entire equipment are achieved through the cooperation between the three. The backward movement is the same. When the number of protective mechanisms 100 is odd, taking three as an example, during the forward movement of the overall pipeline dredging and clearing equipment, the distinction point between the front and rear sections is adjusted according to the required forward speed. When the required forward speed is slightly faster, there is one protective mechanism 100 in the front section and two protective mechanisms 100 in the rear section, and the forward and backward movements are the same as above. When the required forward speed is slightly slower, there are two protective mechanisms 100 in the front section and one protective mechanism 100 in the rear section. During the forward movement, the parallel mechanism 200 located between the protective mechanisms 100 in the front section does not move, and the forward and backward movements are the same as above. The forward speed is adjusted by adjusting the distinction point between the front and rear sections of the overall pipeline dredging and clearing equipment.
[0062] The working principle of this embodiment is as follows: When the overall pipeline dredging and clearing equipment moves forward, the hydraulic system 600 supplies hydraulic oil to the support mechanism 300 and the parallel mechanism 200 through hydraulic pipelines. This sequentially controls the retraction of the support mechanism 300 of the front protective mechanism 100, the extension of the support mechanism 300 of the rear protective mechanism 100, and the synchronous extension of each hydraulic cylinder group of the parallel mechanism 200. After the front protective mechanism 100 reaches the predetermined position, the support mechanism 300 extends and is fixed, the support mechanism 300 of the rear protective mechanism 100 retracts, and the synchronous contraction of each hydraulic cylinder group of the parallel mechanism 200 completes the forward movement. This cycle continues until the entire pipeline is cleared and cleared. The equipment reaches the designated construction position. After the overall pipeline dredging and unblocking equipment reaches the designated construction position, the support mechanisms 300 of the front protection mechanism 100 and the rear protection mechanism 100 extend and fix, so that the overall equipment is fixed and supported. Then, the control system supplies hydraulic oil to the rotating mechanism 500 through the hydraulic pipeline and controls the rotating mechanism 500 to start, so that the water jet mechanism 400 rotates and adjusts the appropriate spray position of the high-pressure water flow to clean and dredge the blockage in the pipeline. After the construction is completed, the hydraulic system 600 supplies hydraulic oil to the support mechanism 300 and the parallel mechanism 200 and controls the overall pipeline dredging and unblocking equipment to retreat. The retreating action is the same as above.
[0063] In one embodiment, the hydraulic drive assembly 330 includes a first connecting rod 331, a second connecting rod 332, and a first hydraulic cylinder 333;
[0064] One end of the first connecting rod 331 and the second connecting rod 332 are rotatably connected to the inner side wall of the protective mechanism 100 through the connecting seat 334, and the other end of the first connecting rod 331 and the second connecting rod 332 are rotatably connected to the support mounting plate 320 through the connecting seat 334.
[0065] The fixed end of the first hydraulic cylinder 333 is rotatably connected to the connecting seat 334 at the end of the first connecting rod 331 located in the protective mechanism 100; the telescopic end of the first hydraulic cylinder 333 is connected to the second connecting rod 332.
[0066] The hydraulic system 600 is connected to the first hydraulic cylinder 333 via hydraulic pipes.
[0067] In this embodiment, refer to Figure 4The hydraulic drive assembly 330 includes a first connecting rod 331, a second connecting rod 332, and a first hydraulic cylinder 333. The hydraulic system 600 is connected to the first hydraulic cylinder 333 through a hydraulic pipeline. When the overall pipeline dredging and clearing equipment moves forward, the support mechanism 300 of the front protection mechanism 100 retracts, and the support mechanism 300 of the rear protection mechanism 100 extends. The extension action of the support mechanism 300 is as follows: the hydraulic system 600 supplies hydraulic oil to the first hydraulic cylinder 333 through hydraulic pipes to control the retraction of the telescopic end of the first hydraulic cylinder 333. Since one end of the first connecting rod 331 and the second connecting rod 332 are rotatably connected to the inner wall of the protective 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 overall equipment. Since the first connecting rod 331 and the second connecting rod 332 are both 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 overall equipment through the support mounting plate 320. After the first connecting rod 331 and the second connecting rod 332 swing in the forward direction of the overall equipment, they will drive the support mounting plate 320 to tilt upward, thereby driving the support body 310 to push outward in the direction of the protective mechanism 100. The first hydraulic cylinder 333 provides a fixing force to fix the support body 310. The retraction action of the support mechanism 300 is similar. When the overall pipeline dredging and clearing equipment moves backward, the support mechanism 300 of the front protection mechanism 100 extends, and the support mechanism 300 of the rear protection mechanism 100 retracts. The specific extension and retraction actions are the same as above.
[0068] In this embodiment, by employing a first connecting rod 331, a second connecting rod 332, and a first hydraulic cylinder 333, in conjunction with a support mounting plate 320 and a support body 310, the entire support mechanism 300 operates in a manner similar to a linkage mechanism. When moving forward or backward, the first hydraulic cylinder 333 provides a fixed thrust, giving the whole structure a fixed supporting force.
[0069] When the overall pipeline dredging and clearing equipment arrives at the construction site to carry out its work, the water jet mechanism is used to clear and clear the blockages in the pipeline. Because the recoil force generated by the water jet mechanism 400 at the front end is as high as 2000N, or about 200 kg, in order to ensure that the overall equipment can operate normally, 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 force generated by the water jet mechanism 400, thereby maintaining the normal operation of the overall equipment.
[0070] In one embodiment, the water jet mechanism 400 includes a first housing 410, a second housing 420, a jet head 430, and an adjustment assembly 440;
[0071] One end of the first cover 410 is sleeved on the front end of the protective mechanism 100 in the forward direction, and the first cover 410 is coaxially rotatably connected to the protective mechanism 100; the other end of the second cover 420 is fixedly connected to the first cover 410, and the second cover 420 is coaxially rotatable with the first cover 410.
[0072] The spray head 430 and the adjustment component 440 are both located inside the second cover 420. The spray head 430 is disposed on the adjustment component 440 and the spray head 430 is slidably connected to the adjustment component 440.
[0073] The second cover 420 has a rectangular water outlet 421 on its end face away from the first cover 410. The adjustment component 440 drives the spray head 430 to slide and adjust in the length direction of the rectangular water outlet 421, and the sliding adjustment amount of the spray head 430 is equal to the length of the rectangular water outlet 421.
[0074] In this embodiment, refer to Figure 5 The water jet mechanism 400 includes a first cover 410, a second cover 420, a jet head 430, and an adjustment assembly 440. The first cover 410 is connected to the rotating mechanism 500 to drive the entire water jet mechanism 400 to rotate circumferentially. The second cover 420 encloses the jet head 430 and the adjustment assembly 440, providing protection for the jet head 430 and the adjustment assembly 440 and facilitating maintenance and installation. The front end face of the second cover 420 is provided with a rectangular water outlet 421, and the rear end face is flat. The adjustment assembly 440 is installed on the front end face of the first cover 410, and the jet head 430 is slidably installed on the adjustment assembly 440. Both the first cover 410 and the second cover 420 are provided with reserved holes at their centers for connecting water pipes to the jet head 430 to provide high-pressure water flow, and the end of the water pipe extends out from the end of the entire device. When the overall pipeline dredging and unblocking equipment arrives at the construction site to start work, the protective mechanism 100 drives the first cover 410 to rotate circumferentially through the rotating mechanism 500, so that the second cover 420 and the spray head 430 and the adjusting component 440 inside the second cover 420 rotate to adjust the spray position of the water jet. At the same time, the adjusting component 440 can drive the spray head 430 to adjust the spray position of the water jet radially. Through the cooperation between the rotating mechanism 500 and the adjusting component 440, the spray position of the water jet is precisely adjusted to clean and unblock the blockage in the pipeline.
[0075] In one embodiment, there are at least two rotating mechanisms 500 arranged radially symmetrically within the protective mechanism 100. Each rotating mechanism 500 includes a drive motor 510, a drive gear 520, and a driven gear ring 530.
[0076] The drive motor 510 is installed on the inner side wall of the protective mechanism 100, and the drive gear 520 is sleeved on the output end of the drive motor 510 and rotates coaxially with the drive motor 510.
[0077] The driven gear ring 530 is fixedly installed at the end of the first cover 410 away from the second cover 420, and meshes with the driving gear 520 to rotate.
[0078] In this embodiment, as Figure 2 , Figure 5 As shown, at least two rotating mechanisms 500 are provided at the connection between the water jet mechanism 400 and the protective mechanism 100 to ensure stable operation of the water jet mechanism 400 when adjusting the spray position of the water jet. The rotating mechanism 500 includes a drive motor 510, a drive gear 520, and a driven gear ring 530. When the rotating mechanism 500 drives the first cover 410 to rotate circumferentially, the second cover 420 and the spray head 430 and the adjusting component 440 inside the second cover 420 rotate accordingly to adjust the position of the water jet. When the water-saving jet is in the spray position, the hydraulic system 600 supplies hydraulic oil to the drive motor 510 through the hydraulic pipeline and controls the drive motor 510. The drive motor 510 drives the drive gear 520 to rotate. The driven gear ring 530 meshes with the drive gear 520 and rotates. The driven gear ring 530 drives the first cover 410 to rotate circumferentially, so that the second cover 420 and the spray head 430 and the adjustment component 440 inside the second cover 420 rotate accordingly to adjust the spray position of the water jet.
[0079] As needed, an axial grinding plate 540 is provided between the end face of the first cover 410 and the end face of the protective mechanism 100 to prevent axial friction under the action of axial force when the two rotate. A radial grinding plate 550 is provided on the side of the connection between the first cover 410 and the protective mechanism 100 to reduce the friction and wear generated when the two rotate under radial force.
[0080] In one embodiment, the adjustment assembly 440 includes a linear slide rail 441 and a second hydraulic cylinder 442;
[0081] The linear slide rail 441 is fixedly installed on the end face where the first cover 410 and the second cover 420 are connected;
[0082] The injection head 430 is mounted on the end of the second hydraulic cylinder 442 and is slidably connected to the linear slide rail 441;
[0083] The output end of the second hydraulic cylinder 442 is connected to the spray head 430, and the spray head 430 is driven by the second hydraulic cylinder 442 to slide at the upper limit of the linear slide rail 441.
[0084] In this embodiment, as Figure 5 , Figure 6 As shown, the adjustment component 440 includes a linear slide rail 441 and a second hydraulic cylinder 442. The spray head 430 is slidably mounted on the linear slide rail 441. The output end of the second hydraulic cylinder 442 is connected to the spray head 430. When the adjustment component 440 drives the spray head 430 to radially adjust the spray position of the water jet, the second hydraulic cylinder 442 drives the spray head 430 to slide and adjust on the linear slide rail 441.
[0085] In one embodiment, the parallel mechanism 200 includes a first end cap 210, a second end cap 220, and a third hydraulic cylinder 230 disposed between the first end cap 210 and the second end cap 220;
[0086] The protective mechanism 100 has a first end 110 and a second end 120. The first end cap 210 is fixedly installed on the second end 120 of the protective mechanism 100, and the second end cap 220 is fixedly installed on the first end 110 of the next section of the protective mechanism 100.
[0087] The output end of the third hydraulic cylinder 230 is rotatably connected to the first end cover 210, and the fixed end of the third hydraulic cylinder 230 is rotatably connected to the second end cover 220.
[0088] The extension and retraction of the third hydraulic cylinder 230 drives the protective mechanism 100 to extend and retract in the forward direction.
[0089] In this embodiment, as Figure 1 , Figure 4 As shown, the parallel mechanism 200 includes a first end cap 210, a second end cap 220, and a third hydraulic cylinder 230. The first end cap 210 and the second end cap 220 serve as support mounting components for the third hydraulic cylinder 230 and also act as a seal, closing both ends of the protective mechanism 100 and protecting it. A pre-drilled hole is provided between the first end cap 210 and the second end cap 220 for passing through a hydraulic pipe to supply hydraulic oil to the rotating mechanism 500 and the support mechanism 300 within the front protective mechanism 100, and for passing through a water pipe to supply high-pressure water to the water jet mechanism 400 of the front protective mechanism 100. Figure 1For example, the first end cap 210 is installed at the second end 120 of the front protection mechanism 100, while the second end cap 220 is installed at the first end 110 of the rear protection mechanism 100. The third hydraulic cylinder 230 is located between the first end cap 210 and the second end cap 220 to connect the two protection mechanisms 100. The output end of the third hydraulic cylinder 230 is connected to the first end cap 210, and the fixed end is connected to the second end cap 220. When the overall pipeline dredging and clearing equipment moves forward in the pipeline, the support mechanism 300 of the front protection mechanism 100 retracts, and the support mechanism 300 of the rear protection mechanism 100 extends. The driving end of the third hydraulic cylinder 230 pushes the front protection mechanism 100 forward to a predetermined position, after which the support mechanism 300 of the front protection mechanism 100 extends and is fixed, and the support mechanism 300 of the rear protection mechanism 100 retracts. The fixed end of the third hydraulic cylinder 230 retracts forward to drive the rear protection mechanism 100 forward, thereby completing the forward movement.
[0090] In one embodiment, the connection between the output end of the third hydraulic cylinder 230 and the first end cover 210, and the connection between the fixed end and the second end cover 220, are both connected by a cylinder mounting base 240.
[0091] In this embodiment, as Figure 4 As shown, the two ends of the third hydraulic cylinder 230 are rotatably connected to the first end cover 210 and the second end cover 220 through the cylinder body mounting seat 240. When the entire pipeline dredging and clearing equipment moves forward or backward in a creeping manner in the pipeline, if it encounters a curved pipeline, the connection points at both ends of the third hydraulic cylinder 230 can adaptively rotate to complete the turning action. The turning of the entire equipment can be achieved by using the cylinder body mounting seat 240 at the connection point.
[0092] In one embodiment, at least two sets of the third hydraulic cylinder 230 are radially symmetrically arranged around the center of the first end cover 210 and the second end cover 220, and the protective mechanism 100 is driven by the symmetrically arranged third hydraulic cylinder 230 to perform six degrees of freedom of twisting in the forward direction.
[0093] In this embodiment, at least two sets of third hydraulic cylinders 230 are radially symmetrically arranged around the center of the first end cover 210 and the second end cover 220. Two third hydraulic cylinders 230 form one set. This hydraulic cylinder set can extend and retract synchronously and asynchronously, and has six degrees of freedom, such as... Figure 4As shown, this embodiment includes three groups of six third hydraulic cylinders 230. When the entire device moves forward or backward along a straight pipe, the third hydraulic cylinders 230 extend or retract synchronously. When the entire device moves forward or backward along a curved pipe, the third hydraulic cylinders 230 extend or retract asynchronously. The output end of the third hydraulic cylinder 230 is mounted on the first end cover 210 via a cylinder mounting base 240, and the fixed end is mounted on the second end cover 220 via a cylinder mounting base 240. The distance from the installation position of the output end of each third hydraulic cylinder 230 to the center of the first end cover 210 is equal, and the distance from the installation position of the fixed end to the center of the second end cover 220 is equal. That is, the output end of each third hydraulic cylinder 230 is located on the same arc, and the fixed end is located on the same arc.
[0094] In a single group, the distance between the output ends of the two third hydraulic cylinders 230 is a1, and the distance between the fixed ends is a2, while a2 is greater than a1, making the two third hydraulic cylinders 230 in the single group have a design similar to a "V".
[0095] In one embodiment, a flexible sleeve 700 is provided at the connection between the protective mechanisms 100, and the parallel mechanism 200 is surrounded by the flexible sleeve 700.
[0096] In this embodiment, as Figure 1 As shown, a flexible sleeve 700 is provided at the connection between the protective mechanisms 100 to provide protection for the parallel mechanism 200, preventing debris, waste residue, etc. from entering the parallel mechanism 200 and causing damage to the parallel mechanism 200.
[0097] In one embodiment, the protective mechanism 100 is provided with a plurality of wheels 800 arranged in a circumferential array on the side wall.
[0098] In this embodiment, as Figure 1 , Figure 6 As shown, the protective mechanism 100 has multiple walking wheels 800 arranged in a circumferential array on its side wall to increase the moving speed and quickly reach the expected working position when the overall pipeline dredging and unblocking equipment moves inside the pipeline.
[0099] As needed, the above-mentioned installation, setting, or connection methods include, but are not limited to, screws, riveting, welding or sleeve, fixing, etc. The installation, setting, or connection method shall be selected according to the working scenario.
