[0030] In a first aspect, an embodiment of the present invention provides an engineering pipeline dredging mechanism, including a support structure 1, a traveling structure 2, a first rotary drive structure 3, a second rotary drive structure 4, and a cleaning structure 5. The traveling structure 2 and the first rotary drive structure 3 are both mounted on the support structure 1. The support structure 1 is used to reciprocate along a first direction via the traveling structure 2. One end of the second rotary drive structure 4 is mounted on the first rotary drive structure 3. The first rotary drive structure 3 is used to extend and retract along the first direction and drive the second rotary drive structure 4 to reciprocate around the first direction. The other end of the second rotary drive structure 4 is used to move closer to or further away from the first rotary drive structure 3. The cleaning structure 5 is mounted on the other end of the second rotary drive structure 4 and is used to extend and retract along the first direction. The second rotary drive structure 4 is used to drive the cleaning structure 5 to reciprocate around the first direction.

[0031] Specifically, such as Figure 1 As shown, the first direction is the Y-axis direction, which is the front of the engineering pipeline dredging mechanism; the support structure 1 can be a frame structure such as a vehicle frame, or a solid structure such as a block. For example, the support structure 1 is a hollow shell; the traveling structure 2 can be a component that combines a track wheel with a track, or a wheel with elastic tires; the first rotary drive structure 3 and the second rotary drive structure 4 can both be driven by a rotary motor or a servo motor; the cleaning structure 5 can be cleaned by a cleaning brush or a cleaning plate; the first rotary drive structure 3, the second rotary drive structure 4, and the cleaning structure 5 can all be extended or retracted by a telescopic hydraulic cylinder or a telescopic electric cylinder.

[0032] In this optional embodiment, such as Figure 1As shown, a pipeline dredging mechanism is constructed comprising a support structure 1, a traveling structure 2, a first rotary drive structure 3, a second rotary drive structure 4, and a cleaning structure 5. The support structure 1 serves as the main support for the entire mechanism, ensuring its operational stability. The traveling structure 2 is mounted on the support structure 1, allowing the support structure 1 to move back and forth, thus enabling the pipeline dredging mechanism to move quickly between different locations within the pipeline. This facilitates dredging of different areas within the pipeline without the need for manual handling, effectively improving dredging efficiency. The first rotary drive structure 3 is mounted on the support structure 1, and one end of the second rotary drive structure 4 is mounted on the first rotary drive structure 3. The first rotary drive structure 3 can extend and retract, driving the second rotary drive structure 4 to move back and forth. Simultaneously, the first rotary drive structure 3 drives the second rotary drive structure 4 to rotate reciprocally in the forward and backward direction. The cleaning structure 5 is mounted on the other end of the second rotary drive structure 4. Thus, driven by the first rotary drive structure 3, the cleaning structure 5 can move back and forth and along an arc-shaped trajectory on a plane perpendicular to the front and back directions. This configuration not only allows the cleaning structure 5 to clean the inner wall of the engineering pipeline at different positions along the front and back directions without moving the engineering pipeline cleaning mechanism, improving cleaning efficiency, but also allows the cleaning structure 5 to effectively clean the entire arc-shaped inner wall of any cross-section of the engineering pipeline, thereby ensuring the cleaning effect of the engineering pipeline. At the same time, the other end of the second rotary drive structure 4 can move closer to or further away from the first rotary drive structure 3, so that the radius of the arc-shaped movement trajectory of the cleaning structure 5 can be adjusted with the extension and retraction of the second rotary drive structure 4, thereby enabling the cleaning structure 5 to perform layered cleaning of impurities in the same engineering pipeline and to clean engineering pipelines of different sizes, expanding the applicability of the engineering pipeline cleaning mechanism. The second rotary drive structure 4 can also drive the cleaning structure 5 to rotate back and forth around the first direction, so that the cleaning structure 5 can clean the pipe wall of the engineering pipeline through the impact force generated by the rotation, ensuring the cleaning effect of the engineering pipeline.

[0033] It should be noted that, in this embodiment, as Figure 1 and Figure 5 As shown, there are multiple second rotary drive structures 4 and cleaning structures 5. The multiple second rotary drive structures 4 are arranged at intervals along the front-back direction, and the multiple cleaning structures 5 are installed one-to-one on the multiple second rotary drive structures 4, so as to realize the synchronous cleaning of different positions on the inner wall of the engineering pipeline and effectively improve the cleaning efficiency.

[0034] It should be noted that the traveling structure 2 can be connected to control elements, thereby enabling remote control of the operation of the traveling structure 2 via a mobile terminal, realizing remote control of the engineering pipeline dredging mechanism when it moves within the engineering pipeline, without the need for manual pushing.

[0035] Optionally, the traveling structure 2 includes multiple pairs of traveling components 21, which are arranged at intervals along a first direction. Any pair of traveling components 21 is symmetrically arranged on both sides of the bottom of the support structure 1 along a second direction, which is perpendicular to the first direction.

[0036] Specifically, such as Figure 1 and Figure 6 As shown, the second direction is the X-axis direction, that is, the left and right direction of the support structure 1. There are four traveling components 21, and the four traveling components 21 are symmetrically arranged in pairs on the left and right sides of the support structure 1.

[0037] In this optional embodiment, such as Figure 1 and Figure 6 As shown, in order to ensure the movement stability of the engineering pipeline dredging mechanism, multiple pairs of traveling components 21 are set to form a traveling structure 2. The multiple pairs of traveling components 21 are arranged at intervals along the front-back direction, thereby ensuring the support stability of the support structure 1 in the front-back direction. At the same time, any pair of traveling components 21 are symmetrically arranged on both sides of the bottom of the support structure 1 along the left-right direction. This not only ensures the support stability of the support structure 1 in the left-right direction, thus ensuring the movement stability of the engineering pipeline dredging mechanism, but also separates the bottom of the support structure 1 from the inner bottom wall of the engineering pipeline through the supporting effect of the traveling components 21, preventing impurities on the inner bottom wall of the engineering pipeline from hindering the movement of the engineering pipeline dredging mechanism.

[0038] Optionally, the traveling assembly 21 includes a first rotary drive, a first rotary shaft 211, a first telescopic rod 212, and a caster wheel 213. The first rotary drive is mounted on the support structure 1 and is drivenly connected to the first rotary shaft 211, and is used to drive the first rotary shaft 211 to reciprocate around a first direction. One end of the first telescopic rod 212 is vertically mounted on the first rotary shaft 211, and the other end of the first telescopic rod 212 is connected to the caster wheel 213, and is used to move closer to or away from one end of the first telescopic rod 212.

[0039] Specifically, such as Figure 2 As shown, the first rotary drive component is installed inside the support structure 1. The first rotary drive component can be a drive motor or a servo motor. The first telescopic rod 212 can be an electric telescopic rod or a telescopic rod driven by a hydraulic cylinder.

[0040] In this optional embodiment, to ensure the stability of the pipeline dredging mechanism, such as... Figure 1 and Figure 2As shown, a traveling assembly 21 is composed of a first rotary drive unit, a first rotary shaft 211, a first telescopic rod 212, and a caster wheel 213. The first rotary drive unit is mounted on the support structure 1 and is driven to the first rotary shaft 211, thereby driving the first rotary shaft 211 to rotate in the front-back direction. Simultaneously, one end of the first telescopic rod 212 is vertically mounted on the first rotary shaft 211, allowing the other end of the first telescopic rod 212 to move along an arc-shaped trajectory around the axis of the first rotary shaft 211 through rotation of the first rotary shaft 211. The caster wheel 213 is mounted on the other end of the first telescopic rod 212. This arrangement allows the caster wheel 213 to move along an arc-shaped trajectory in the front-back direction. Therefore, when the engineering pipeline dredging mechanism is located inside the engineering pipeline, the caster wheel 213 can... By adjusting its position on the same cross-section of the pipe wall, it avoids impurities inside the engineering pipeline and abuts against the inner wall of the curved engineering pipeline, ensuring smooth forward and backward movement of the engineering pipeline dredging mechanism. When it is removed from the engineering pipeline and needs to be moved on a plane, the rotation of the first rotating shaft 211 can cause the first telescopic rod 212 to be arranged vertically, ensuring the stability of the engineering pipeline dredging mechanism on the plane, thus facilitating the transportation and relocation of the engineering pipeline dredging mechanism. Moreover, the first telescopic rod 212 can also extend and retract axially, thereby adjusting the distance between the universal wheel 213 and the bottom of the support structure 1. In turn, the support of the traveling component 21 adjusts the distance between the bottom of the support structure 1 and the inner bottom wall of the engineering pipeline, making it easier to avoid impurities on the inner bottom wall of the engineering pipeline.

[0041] Optionally, the second rotary drive structure 4 includes a second telescopic rod 41 and a second rotary drive member 42. One end of the second telescopic rod 41 is mounted on the first rotary drive structure 3, and the other end of the second telescopic rod 41 is connected to the second rotary drive member 42 and is used to move closer to or away from one end of the second telescopic rod 41. The second rotary drive member 42 is drivenly connected to the cleaning structure 5 and is used to drive the cleaning structure 5 to reciprocate around the first direction.

[0042] Specifically, such as Figure 1 As shown, the second rotary drive component 42 can be a drive motor or a servo motor, and the second telescopic rod 41 can be an electric telescopic rod or a telescopic rod driven by a hydraulic cylinder.

[0043] In this optional embodiment, such as Figure 1As shown, a second telescopic rod 41 and a second rotary drive component 42 are configured to form a second rotary drive structure 4. One end of the second telescopic rod 41 is mounted on the first rotary drive structure 3, allowing the other end of the second telescopic rod 41 to move along an arc-shaped trajectory in the front-back direction via the first rotary drive structure 3. The second rotary drive component 42 is mounted on the other end of the second telescopic rod 41 and is connected to the cleaning structure 5, thereby driving the cleaning structure 5 to move along an arc-shaped trajectory in the front-back direction. This allows the cleaning structure 5 to move between different positions on the same cross-section of the engineering pipeline. The second rotary drive component 42 can also drive the cleaning structure 5 to rotate in the front-back direction, thus achieving effective sludge removal at different positions on the same cross-section of the engineering pipeline and improving the sludge removal effect. At the same time, the second telescopic rod 41 can extend and retract to adjust the radius of the arc-shaped trajectory of the cleaning structure 5, thereby enabling the cleaning structure 5 to perform layered cleaning of impurities in the same engineering pipeline and to perform sludge removal operations on engineering pipelines of different sizes, thus expanding the applicability of the engineering pipeline sludge removal mechanism.

[0044] Optionally, the support structure 1 includes a support base 11, a traveling structure 2 is installed at the bottom of the support base 11, a first rotary drive structure 3 is installed at the top of the support base 11, and a notch 111 is provided on the side wall of the support base 11. The first rotary drive structure 3 is used to drive the second rotary drive member 42 to move into or out of the notch 111, so that the cleaning structure 5 moves into or out of the underside of the support structure 1.

[0045] Specifically, such as Figure 1 and Figure 5 As shown, the bottom wall of the support base 11 is arc-shaped, and the left and right side walls of the support base 11 are provided with grooves that communicate with the bottom wall. The traveling component 21 is installed in the groove, and the second rotating drive component 42 can pass through the notch 111.

[0046] In this optional embodiment, in order to ensure the sludge removal effect of the cleaning structure 5, such as Figure 1 and Figure 5 As shown, the support structure 1 is provided with a support base 11, wherein the traveling structure 2 is installed at the bottom of the support base 11, and the first rotary drive structure 3 is installed at the top of the support base 11 to ensure the structural stability and movement stability of the engineering pipeline dredging mechanism; on this basis, a notch 111 is provided on the side wall of the support base 11, wherein when the first rotary drive structure 3 drives the second rotary drive component 42 to rotate in the front-back direction, the notch 111 is located on the movement trajectory of the second rotary drive component 42, thereby allowing the second rotary drive component 42 to move into or out of the notch 111. The notch 111 allows the support base 11 to make way for the movement of the second rotary drive component 42, avoiding the support base 11 from obstructing the movement of the second rotary drive component 42, thereby enabling the second rotary drive component 42 to drive the cleaning structure 5 to move into and out of the support structure 1, thereby realizing the dredging operation of the inner wall of the engineering pipeline below the support structure 1.

[0047] It should be noted that, as Figure 1 and Figure 5 As shown, when there are multiple second rotary drive components 42, there are also multiple notches 111. The multiple notches 111 are arranged at intervals along the front-back direction, and two adjacent notches 111 are located on opposite sides of the support base 11. This arrangement not only ensures the structural stability of the support base 11, but also enables all-round cleaning of the inner wall of the engineering pipeline through the cooperation of the cleaning structures 5 on two adjacent second rotary drive components 42, effectively improving the cleaning effect and cleaning efficiency.

[0048] Optionally, the cleaning structure 5 includes a third telescopic rod 51 and a scraper 52. The third telescopic rod 51 is used to extend and retract along a first direction and is connected to the second rotary drive member 42. The scraper 52 has multiple scrapers and is arranged alternately on the third telescopic rod 51. When the trajectory of the third telescopic rod 51 driven by the first rotary drive structure 3 through the second rotary drive member 42 passes through the traveling structure 2, the third telescopic rod 51 is used to shorten along the first direction so that the traveling structure 2 moves away from the trajectory of the third telescopic rod 51.

[0049] Specifically, such as Figure 3 As shown, the third telescopic rod 51 can be a telescopic rod driven by a telescopic electric cylinder or a telescopic rod driven by a telescopic hydraulic cylinder. The third telescopic rod 51 includes a support cylinder and a moving rod. The moving rod extends into the support cylinder through the open end of the support cylinder. The support cylinder has a groove on its wall to facilitate the movement of the scraper 52 on the moving rod into and out.

[0050] In this optional embodiment, such as Figure 3 As shown, a cleaning structure 5 is formed by a third telescopic rod 51 and scrapers 52. The third telescopic rod 51 is connected to the second rotary drive member 42, and multiple scrapers 52 are staggered on the third telescopic rod 51. When the second rotary drive member 42 drives the third telescopic rod 51 to rotate in the front-back direction, it can drive the scrapers 52 to move, thereby generating an impact on the impurities on the inner wall of the pipeline, achieving sludge removal. At the same time, in order to enable the cleaning structure 5 to move in and out of the support structure 1 to achieve sludge removal on the inner bottom wall of the pipeline, when the trajectory of the third telescopic rod 51 driven by the first rotary drive structure 3 through the second rotary drive member 42 passes through the traveling structure 2, that is, when the traveling structure 2 obstructs the movement of the third telescopic rod 51, the third telescopic rod 51 can be shortened in the first direction, so that the trajectory of the third telescopic rod 51 does not pass through the traveling structure 2, that is, the traveling structure 2 is away from the trajectory of the third telescopic rod 51, thereby ensuring that the cleaning structure 5 can move in and out of the support structure 1.

[0051] Optionally, the first rotary drive structure 3 includes a third rotary drive member 31, a fourth telescopic rod 32, and a sleeve 33. The third rotary drive member 31 is mounted on the support structure 1 and is driven to connect with the fourth telescopic rod 32 to drive the fourth telescopic rod 32 to reciprocate around a first direction. The sleeve 33 is fitted onto the fourth telescopic rod 32, and the fourth telescopic rod 32 is used to extend and retract to drive the sleeve 33 to reciprocate along the first direction. The end of the second rotary drive structure 4 is mounted on the sleeve 33.

[0052] Specifically, such as Figure 1 As shown, the third rotary drive component 31 can be a drive motor or a servo motor, and the fourth telescopic rod 32 can be an electric telescopic rod or a telescopic rod driven by a hydraulic cylinder.

[0053] In this optional embodiment, such as Figure 1 , Figure 5 and Figure 6 As shown, a first rotary drive structure 3 is formed by a third rotary drive component 31, a fourth telescopic rod 32, and a sleeve 33. The third rotary drive component 31 is mounted on the support structure 1 and is drivenly connected to the fourth telescopic rod 32, thus ensuring the working stability of the first rotary drive structure 3 and enabling the fourth telescopic rod 32 to rotate in the front-back direction through the driving action of the third rotary drive component 31. The sleeve 33 is fitted onto the fourth telescopic rod 32, and the end of the second rotary drive structure 4 is mounted on the sleeve 33. Thus, the rotation of the fourth telescopic rod 32 drives the sleeve 33 to rotate, thereby driving the second rotary drive structure 4 to move. Based on this, the fourth telescopic rod 32 can extend and retract, thereby driving the sleeve 33 to move in the front-back direction, thereby driving the second rotary drive structure 4 to move in the front-back direction, realizing flexible adjustment of the position of the cleaning structure 5.

[0054] Optionally, the support structure 1 includes a support platform 12 and a sliding seat 13. The support platform 12 and the third rotary drive member 31 are spaced apart along the first direction, and the top end is recessed to form a placement groove. The sliding seat 13 is embedded in the placement groove. The upper end surface of the sliding seat 13 is a smooth arc surface, and its shape matches the shape of the fourth telescopic rod 32. The fourth telescopic rod 32 is placed on the upper end surface of the sliding seat 13.

[0055] In this optional embodiment, in order to ensure the stable rotation of the fourth telescopic rod 32 and the stable movement of the sleeve 33, such as Figure 1 and Figure 4As shown, a support structure 1 is formed by a support platform 12 and a sliding seat 13. The support platform 12 and the third rotary drive 31 are spaced apart in the front-to-back direction. The top of the support platform 12 is recessed to form a placement groove, and the sliding seat 13 is embedded in the placement groove. The upper surface of the sliding seat 13 is a smooth arc surface, and its shape matches the shape of the fourth telescopic rod 32. In this way, after the fourth telescopic rod 32 is driven and connected to the third rotary drive 31, it can be placed on the upper surface of the sliding seat 13. The sliding seat 13 can stably support the fourth telescopic rod 32, ensuring the stable rotation of the fourth telescopic rod 32 and the stable movement of the sleeve 33. Based on this, since the size of the fourth telescopic rod 32 required for dredging different engineering pipelines is different, different sliding seats 13 can be replaced according to the specific size of the fourth telescopic rod 32, thereby meeting the dredging needs of different engineering pipelines.

[0056] Optionally, the engineering pipeline dredging mechanism further includes a recovery structure 6, which is arranged at intervals with the first rotary drive structure 3 along the first direction, and includes a suction head 61 and a negative pressure box 62. The negative pressure box 62 is installed on one side of the support structure 1 along the first direction and communicates with the receiving chamber of the support structure 1. The suction head 61 is installed at the bottom of the negative pressure box 62 and communicates with the negative pressure box 62. The inlet of the suction head 61 faces downwards from the support structure 1.

[0057] Specifically, the negative pressure box 62 is connected to a negative pressure fan, and the receiving chamber of the support structure 1 is located in the impurity box on it. The impurity box can be moved into and out of the support structure 1, and can also be connected to the sewage pipe. The bottom wall of the suction head 61 is an arc shape that matches the inner wall shape of the engineering pipeline.

[0058] In this optional embodiment, to avoid impurities obstructing the movement of the pipeline dredging mechanism, such as... Figure 1 and Figure 5 As shown, a recovery structure 6 is also provided, wherein the recovery structure 6 and the first rotary drive structure 3 are arranged at intervals along the front-back direction, and include a suction head 61 and a negative pressure box 62. The negative pressure box 62 is installed on one side of the support structure 1 along the first direction and is connected to the receiving chamber of the support structure 1. The suction head 61 is installed at the bottom of the negative pressure box 62 and is connected to the negative pressure box 62. The input port of the suction head 61 faces downwards from the support structure 1. With this configuration, after the cleaning structure 5 flushes away the impurities on the inner wall of the engineering pipeline, the impurities will accumulate on the inner bottom wall of the engineering pipeline. At this time, the negative pressure effect generated at the input end of the suction head 61 by the negative pressure box 62 can be used to suck the impurities on the inner bottom wall of the engineering pipeline into the receiving chamber through the suction head 61 and the negative pressure box 62. This avoids the impurities from hindering the movement of the engineering pipeline cleaning mechanism and ensures the stability of the engineering pipeline cleaning mechanism in use.

[0059] Secondly, one embodiment of this utility model provides a maintenance device, including a pipeline repair device and the aforementioned engineering pipeline dredging mechanism.

[0060] The technical effects of the maintenance equipment in this embodiment are similar to those of the engineering pipeline dredging mechanism described above, and will not be repeated here.

[0061] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
