TECHNICAL FIELD

[0001] The application relates to the technical field of pipeline cleaning devices, in particular to a municipal drainage pipeline foreign matter breaking and cleaning device under complex geological conditions. BACKGROUND

[0002] In related technologies, when tunneling construction is performed at the bottom of an existing drainage pipeline, due to poor geological conditions of the pipeline and damage of the existing drainage pipeline due to long-term disrepair, holes and water pockets are prone to appear in the soil under the drainage pipeline. In order to reduce the situation that water and silt in the water pockets easily break through the soil layer into the tunnel and cause tunnel collapse during subsequent tunneling construction, after temporarily stopping water in the drainage pipeline, a plurality of bored piles are drilled at the bottom of the drainage pipeline, and the bored piles are used to realize reinforcement and water stopping of the soil above the tunnel.

[0003] In the related technologies, when the bored piles are drilled at the bottom of the drainage pipeline, part of the concrete is prone to flow into the drainage pipeline through the damaged part between the drainage pipelines to form concrete block objects, which seriously affects the water flow of the subsequent drainage pipeline. SUMMARY

[0004] In order to facilitate the cleaning of the concrete block objects formed by the concrete flowing into the drainage pipeline when the bored piles are drilled, the application provides a municipal drainage pipeline foreign matter breaking and cleaning device under complex geological conditions.

[0006] The municipal drainage pipeline foreign matter breaking and cleaning device under complex geological conditions comprises a movable chassis, a breaking assembly and a cleaning assembly. The breaking assembly comprises a plurality of high-pressure water guns arranged at the front end of the movable chassis. The cleaning assembly comprises a slurry pump arranged on the movable chassis. The slurry pump is connected with a water inlet pipe and a water outlet pipe. The water inlet pipe extends out of the front end of the movable chassis and is arranged vertically downward.

[0007] Through the above technical scheme, the movable chassis drives the cleaning assembly and the breaking assembly to move to the position of the concrete block objects in the pipeline. The high-pressure water guns are used to impact and break the concrete block objects. The slurry pump is used to suck and treat the sludge in the drainage pipeline and the broken concrete block objects. In this way, the breaking and cleaning of the concrete block objects in the drainage pipeline are realized, and the problem of the concrete block objects in the drainage pipeline affecting the flow of the drainage pipeline during daily use of the drainage pipeline is reduced.

[0008] Preferably, the movable chassis front end is further vertically provided with a grid plate, the grid plate is located on the side of the water inlet pipe away from the movable chassis, and a projection of the grid plate on a vertical plane covers a projection of the water inlet pipe on the vertical plane.

[0009] By adopting the above technical scheme, larger concrete block-shaped objects can be filtered out by the grid plate, so as to reduce the situation that the larger concrete block-shaped objects are sucked into the water inlet pipe by the slurry pump, thereby causing the water inlet pipe to be blocked.

[0010] Preferably, the top side of the grid plate is provided with a plurality of connecting sleeves corresponding to a plurality of high-pressure water guns, the high-pressure water guns are all arranged in the corresponding connecting sleeves, a plurality of resisting bolts are threadedly arranged on the outer periphery of the connecting sleeves, the resisting bolts extend into the inner cavities of the connecting sleeves and abut against the outer periphery of the high-pressure water guns.

[0011] By adopting the above technical scheme, the high-pressure water guns are inserted into the connecting sleeves and the resisting bolts are tightened, so that the high-pressure water guns are detachably connected to the grid plate, and the high-pressure water guns and the grid plate do not need to be integrally formed, which facilitates the disassembly and replacement of the high-pressure water guns.

[0015] By adopting the above technical scheme, the connecting sleeve can be driven to rotate around the own rotation axis by the extension and retraction of the piston rod of the driving cylinder, the adjustment of the orientation angle of the high-pressure water gun is realized, and the orientation adjustment of the high-pressure water gun is more simple and convenient.

[0016] Preferably, the opposite ends of the grid plate are both provided with a baffle member, the baffle member comprises a support rod, a connecting rod, a flexible rod and a waterproof cloth, the support rod is vertically and rotatably connected to the end of the grid plate and extends to the bottom side of the grid plate, the connecting rod and the flexible rod are respectively perpendicularly connected to the top end and the bottom end of the support rod, and the waterproof cloth is tensioned and connected to the support rod, the connecting rod and the flexible rod; the end of the grid plate is further provided with a secondary driving member for driving the support rod to rotate around the own axis.

[0017] By adopting the technical scheme, before the high-pressure water gun breaks the concrete accumulation, the sub-driving element drives the support rod to rotate until the gap between the movable chassis side and the drainage pipeline is blocked by the baffle formed by the support rod, the connecting rod, the flexible rod and the waterproof cloth, so that the mixed sewage such as the sludge in the pipeline and the broken concrete accumulation fragments flows to and accumulates on both sides of the movable chassis during the movement of the movable chassis or the impact and breaking of the concrete accumulation by the high-pressure water gun, so that the subsequent slurry pump cannot be used for pumping and cleaning; before the slurry pump is used for pumping and cleaning the concrete accumulation fragments and the sludge, the sub-driving element drives the two groups of baffles to swing towards each other, so that the concrete accumulation fragments and the sludge are gathered, and then the slurry pump can be used for pumping the concrete accumulation fragments and the sludge.

DETAILED DESCRIPTION

[0032] The following will be described in detail in combination with the accompanying Figures 1-4 The present application will be further described in detail.

[0033] The embodiment of the present application discloses a municipal drainage pipeline foreign matter breaking and cleaning device under complex geological conditions, referring to Figure 1 and Figure 2 , comprising a movable chassis 1, a breaking assembly, a cleaning assembly, a camera 4, and a terminal control unit.

[0034] Referring to Figure 1 and Figure 2The crushing component includes several high-pressure water guns 2 mounted on the front end of the movable chassis 1; the cleaning component includes a slurry pump 3 mounted on the movable chassis 1, with an inlet pipe 31 and an outlet pipe 32 connected to the inlet and outlet of the slurry pump 3, respectively; the inlet pipe 31 extends to the lower front end of the movable chassis 1 and extends vertically downwards, with a suction hood 33 connected to the end of the inlet pipe 31, facilitating the slurry pump 3 to better suction concrete debris and sludge through the inlet pipe 31. A frame 41 is fixed to the upper surface of the movable chassis 1 corresponding to the camera 4, and the camera 4 is installed at the top of the frame 41, facilitating real-time acquisition of the internal conditions of the pipes through the camera 4.

[0035] In this embodiment, the movable chassis 1 is an existing tracked chassis, which facilitates the movement of the movable chassis 1 in complex environments; the high-pressure water gun 2, the slurry pump 3 and the movable chassis 1 are all electrically connected to the terminal control unit, which is an existing control box, and the control box is equipped with an internal computer control system consisting of a dual-core CPU industrial control motherboard, an LCD display, an SS storage disk and a video acquisition module.

[0036] Reference Figure 1 and Figure 2 A grating plate 5 is also mounted on the front end of the movable chassis 1. The grating plate 5 is located on the side of the inlet pipe 31 away from the movable chassis 1. The vertical projection of the grating plate 5 covers the vertical projections of the inlet pipe 31 and the suction hood 33. The grating plate 5 filters out larger fragments of broken concrete, reducing the likelihood of these fragments clogging the inlet pipe 31 of the slurry pump 3. Two sets of fixing rods 51 are vertically connected to the top side of the grating plate 5. The ends of the two sets of fixing rods 51 away from the grating plate 5 are fixed to the movable chassis 1, thus securing the grating plate 5.

[0037] Several high-pressure water guns 2 are hinged to the top of the grating plate 5, and several connecting sleeves 21 are hinged to them. The rotation axis of the connecting sleeve 21 is perpendicular to its own axis and perpendicular to the travel direction of the movable chassis 1. The high-pressure water guns 2 are inserted into the corresponding connecting sleeves. The outer circumference of the connecting sleeve 21 is also threaded with a clamping bolt 22. The bottom end of the clamping bolt 22 extends into the inner cavity of the connecting sleeve 21 and clamps against the high-pressure water gun 2. Through the above settings, the high-pressure water guns 2 can be detachably connected to the grating plate 5, which is convenient for disassembly and replacement of the high-pressure water guns 2. At the same time, the swing angle of the high-pressure water guns 2 can be adjusted, which is convenient for adjusting the placement angle of the high-pressure water guns 2 in real time according to the volume and position of the concrete pile, so that the several high-pressure water guns 2 can better impact and break the concrete pile.

[0038] A support plate 24 is also provided above the grating plate 5. The support rod 61 is connected between the two sets of fixed rods 51. The main drive component 23 includes a drive cylinder provided on the support plate 24. The drive cylinders are electrically connected to the terminal control unit. The two ends of the drive cylinder are respectively hinged to the support plate 24 and the corresponding connecting sleeve 21. The rotation axis of the two ends of the drive cylinder is parallel to the rotation axis of the connecting sleeve. The connecting sleeve 21 can be swung by driving its piston rod to extend and retract, which facilitates the adjustment of the placement angle of the high-pressure water gun 2.

[0039] Reference Figure 1 and Figure 3 Both ends of the grating plate 5 are provided with baffles 6, each baffle 6 including a support rod 61, a connecting rod 62, a flexible rod 63, and a waterproof cloth 64. Mounting plates 52 are horizontally connected to the top of both ends of the grating plate 5. A support plate 24 is vertically rotatably connected to the mounting plate 52, and the bottom end of the support rod 61 extends to the bottom side of the grating plate 5. The connecting rod 62 and the flexible rod 63 are vertically connected to the top and bottom ends of the support rod 61, respectively. The waterproof cloth 64 is tensioned and connected to the support rod 61, the connecting plate, and the flexible rod 63. The waterproof cloth 64, support rod 61, connecting rod 62, and flexible rod 63 combine to form a plate-like structure. A secondary drive component 65 is also provided at the end of the grating plate 5 to drive the support rod 61 to rotate. The secondary drive component 65 includes a drive motor mounted on the mounting plate 52, and the output shaft of the drive motor is coaxially connected to the top end of the support rod 61.

[0040] Reference Figure 3 and Figure 4 With the above settings, during the movement of the movable chassis 1, the two sets of auxiliary drive components 65 drive the corresponding support rods 61 to rotate, thereby driving the two sets of baffle components 6 to swing in a direction away from each other, until the two sets of baffle components 6 block the gaps between the two sides of the movable chassis 1 and the pipeline, thereby reducing the flow of concrete debris and sludge mixed with sewage to the sides of the movable chassis 1 during the movement of the movable chassis 1 or during the crushing of concrete debris by the high-pressure water gun 2, which would make it difficult for the sludge and concrete debris to be collected and cleaned by the slurry pump 3.

[0041] In this embodiment, the flexible rod 63 is a PVC plastic rod with a rectangular cross-section and a width greater than its thickness. This allows the flexible rod 63 to better adapt to the inner contour of the drainage pipe during the rotation of the baffle 6, enabling the baffle 6 to better seal the gap between the movable chassis 1 and the drainage pipe. Several bristles are fixed to the bottom side of the grating plate 5 and the lower surface of the flexible rod 63. During the downward movement of the movable chassis 1, the bristles of both the grating plate 5 and the flexible rod 63 can brush away the sludge and impurities at the bottom of the drainage pipe, achieving further cleaning of the drainage pipe.

[0042] The implementation principle of this application embodiment is as follows: Before the drainage pipe resumes normal water flow, the movable chassis 1 is placed into the drainage pipe through the inspection well. Two sets of auxiliary drive components 65 drive two sets of baffle components 6 to swing until the two sets of baffle components 6 respectively block the gaps between the movable chassis 1 and the drainage pipe on both sides. Construction personnel control the movable chassis 1 to move inside the drainage pipe through the control system of the control box on the ground. During the movement of the movable chassis 1, the camera 4 feeds back the real-time image inside the pipe to the control box. When the movable chassis 1 moves to the concrete accumulation, the concrete accumulation is impacted and broken by the high-pressure water gun 2. Finally, the two sets of auxiliary drive components 65 drive the two sets of baffle components 6 to swing in a direction closer to each other until the two sets of baffle components 6 form an flared shape, realizing the collection of concrete accumulation fragments, sludge, sewage, etc. At the same time, in conjunction with the continued movement of the movable chassis 1, the concrete fragments, sludge, sewage, etc. are sucked out and cleaned by the slurry pump 3. This achieves the breaking and cleaning of concrete accumulation in the drainage pipe, reducing the impact of concrete accumulation on drainage.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
