Description

Technical Field

[0001] This invention relates to the field of dredging robot technology, specifically a multi-functional dredging robot. Background Technology

[0002] Dredging robots are specialized equipment combining automation and robotics technologies, widely used for sludge removal in rivers, culverts, and sewage ponds. These robots are typically deployed into the site and use their built-in pumps to draw sludge into pipes for discharge. An auger is installed at the suction point to break up and gather the sludge, improving suction efficiency. However, during pipe transport, some sections are curved, and the sludge may contain particles of varying sizes. This can cause blockages, especially at bends. Furthermore, because the sludge is pumped, near the pipe outlet, flow resistance and friction from internal particles consume pump energy, reducing transport capacity and increasing the risk of blockages. This process is quite inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a multifunctional dredging robot to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A multi-functional dredging robot includes a robot body, on which a discharge pipe is installed, characterized in that it includes:

[0006] The system comprises multiple connecting pipes, multiple conduits, multiple flushing mechanisms for flushing sludge from inside the connecting pipes, and a housing. The connecting pipes are arranged horizontally in sequence, with one connecting pipe fixedly connected to a discharge pipe via a flange. The outer walls of the multiple conduits are provided with slots, and each conduit is fixedly connected between two adjacent connecting pipes. The multiple flushing mechanisms correspond one-to-one with the multiple conduits. Each flushing mechanism includes a water storage shell located inside an adjacent conduit. The outer wall of the water storage shell is provided with a groove, and an inlet pipe is installed inside the groove, passing through the adjacent slot. Both ends of the water storage shell are provided with spray shells, and multiple fixed pipes are fixedly connected between each spray shell and the water storage shell. Multiple spray heads are fixedly connected to one side of each spray shell. A water pump is installed inside the housing.

[0007] Furthermore, two sealing plates are fixedly fitted onto the outer wall of any water inlet pipe. The two sealing plates on any water inlet pipe are located inside and outside the adjacent conduit, respectively. The length and width of any sealing plate are greater than the length and width of the groove.

[0008] Furthermore, each inlet pipe is fixedly connected to a collar at its bottom, the inside of each collar is slidably sleeved with the outer wall of the adjacent water storage shell, each collar is fixedly connected to a retaining plate on both sides, each slide groove has a retaining groove on its inner side wall, and each retaining plate is slidably engaged with the inside of the adjacent retaining groove.

[0009] Furthermore, each water storage shell has multiple supporting arms rotatably connected to both ends, and the multiple supporting arms at the same end of each water storage shell are arranged circumferentially. A rubber tube is fixedly connected between the multiple supporting arms at the same end of each water storage shell. Each rubber tube has an open structure at one end, and multiple circular holes are opened at the other end of each rubber tube. Each fixed tube is fixedly sleeved with an adjacent circular hole.

[0010] Furthermore, each water storage tank has two sliding rings attached to its outer wall. Each sliding ring has multiple guide rods rotatably connected to its outer wall. Each sliding ring is located near both ends of an adjacent water storage tank. The multiple guide rods on each sliding ring correspond one-to-one with the multiple support arms at the ends of the adjacent water storage tanks. One end of each guide rod is rotatably connected to the outer wall of the corresponding support arm.

[0011] Furthermore, each moving ring is fixedly connected to an adjacent collar with multiple rebound springs.

[0012] Furthermore, each movable ring is fixedly connected to its adjacent ring with multiple pull ropes.

[0013] Furthermore, each water spray shell has a piston plate slidably sleeved inside, each piston plate is fixedly connected to one end of the interior of the adjacent water spray shell with multiple return springs, each water spray shell has multiple insertion holes at one end, each piston plate has multiple positioning rods fixedly connected to one side, each positioning rod is slidably sleeved with the adjacent insertion hole, each adjacent rinsing mechanism is provided with an agitation rope, each agitation rope has fixed plates fixedly connected to both ends, and each fixed plate is fixedly connected to the adjacent positioning rod.

[0014] Furthermore, a counterweight is fixedly attached to the middle of each agitation cable.

[0015] Furthermore, each inlet pipe has a ring fixedly connected to a sealing plate located outside the adjacent conduit, and each conduit has a threaded hole on its outer side wall.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By connecting a connecting pipe to the discharge pipe, multiple conduits and connecting pipes are used to transport sludge. When a blockage occurs, a water pump can be connected to a flushing mechanism near the blockage. The flushing mechanism can then flush water near the blockage and perform forward or reverse flushing to clear the blockage.

[0018] 2. By connecting the water pump to the inlet pipe through a water pipe, water is injected into the inlet pipe using the water pump. By sliding the inlet pipe, the inlet pipe and the collar are pulled by a rope, causing one movable ring to move while the other movable ring remains stationary. As one movable ring moves, it drives multiple adjacent support arms to rotate through a guide rod. The rotating support arms stretch and unfold the adjacent rubber cylinders, so that one spray shell is no longer covered by the adjacent rubber cylinder. The other movable ring remains stationary, causing the adjacent support arms to press the adjacent rubber cylinders to cover another spray shell. This allows water to spray out from the nozzle of one spray shell to flush the blockage and block the sludge inside the pipe by the unfolded rubber cylinder, reducing the flow of sludge.

[0019] 3. By moving the water inlet pipe, any rubber cylinder in the flushing mechanism can be unfolded. Then, the water flow flows along the surface of the unfolded rubber cylinder and rushes into the pipe for flushing. This makes the water flow form a ring-shaped flow to flush the inner wall of the pipe, improving the flushing effect. Furthermore, by controlling the connection between the water pump and the water inlet pipe near the blockage, and pushing and controlling the movement direction of the water inlet pipe near the blockage, the blockage can be flushed in both forward and reverse directions.

[0020] 4. When the water pump injects water into the inlet pipe for flushing, it uses an intermittent water injection method. When the water flows into the spray shell, it pushes the piston plate to move. Then the water flows out from the spray head. At this time, the piston plate drives the positioning rod to move, which loosens the adjacent stirring rope. Then, when the water flows and impacts the sludge, it will simultaneously impact the stirring rope, allowing the stirring rope to move freely and guide the sludge. After the water injection stops, the piston plate resets under the action of the return spring and straightens the stirring rope again. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-9 In this embodiment of the invention, a multifunctional dredging robot includes a robot body 100, and the robot body 100 is equipped with a discharge pipe 110 for discharging the pumped sludge, comprising:

[0033] The system comprises multiple connecting pipes 200, multiple conduits 300, multiple flushing mechanisms 400 for flushing sludge from inside the connecting pipes 200, and a housing 500. The connecting pipes 200 are arranged horizontally in sequence. One connecting pipe 200 is fixedly connected to a discharge pipe 110 via a flange. The outer walls of the multiple conduits 300 are each provided with a slot. Each conduit 300 is fixedly connected between two adjacent connecting pipes 200. The multiple flushing mechanisms 400 correspond one-to-one with the multiple conduits 300. 400 includes a water storage shell 410, which is located inside the adjacent conduit 300. The outer wall of the water storage shell 410 is provided with a groove, and an inlet pipe 420 is provided inside the groove. The inlet pipe 420 passes through the adjacent groove opening. Both ends of the water storage shell 410 are provided with water spray shells 430. Multiple fixed pipes 431 are fixedly connected between any water spray shell 430 and the water storage shell 410. Multiple spray heads are fixedly connected to one side of any water spray shell 430. A water pump is provided inside the box body 500.

[0034] Specifically, the robot body 100 is an existing sludge-clearing robot, which can use its own pump to suck up sludge and discharge it through the discharge pipe 110. The connecting pipe 200 is a flexible hose, which mainly serves to transport sludge. The conduit 300 is a rigid pipe. The water storage tank 410 and the spray tank 430 are both hollow structures. When sludge blockage occurs, the water pump inside the housing 500 can be connected to a water pipe, and then the water pipe can be connected to the inlet pipe 420 near the blockage. The water pump will then pump water through the water pipe into the connected inlet pipe 420, so that the water in the inlet pipe 420 enters the adjacent water storage tank 410 and then enters the adjacent spray tank 430 through the fixed pipe 431. The water is then sprayed from the nozzles on the spray tank 430 to flush the sludge at the blockage, thereby facilitating the clearing of sludge blockage in the pipe and allowing the sludge in the pipe to move with the help of the water flow. This allows the water flow to flush the sludge near the blockage, increasing the impact on the sludge and facilitating the clearing of the pipe.

[0035] Example 1

[0036] like Figures 4-6 As shown, in this embodiment, two sealing plates 421 are fixedly sleeved on the outer wall of any water inlet pipe 420. The two sealing plates 421 on any water inlet pipe 420 are located inside and outside the adjacent conduit 300, respectively. The length and width of any sealing plate 421 are greater than the length and width of the groove. A collar 422 is fixedly connected to the bottom of any water inlet pipe 420. The inside of any collar 422 is slidably sleeved with the outer wall of the adjacent water storage shell 410. A retaining plate 423 is fixedly connected to the opposite sides of any collar 422. A retaining groove is opened on the inner side wall of any sliding groove. The retaining plate 423 is slidably retaining itself in the adjacent retaining groove.

[0037] In this embodiment, the outer surfaces of the two sealing plates 421 are covered with a rubber layer and abut against the surface of the conduit 300, thereby sealing the groove opening with the sealing plates 421 to prevent silt from leaking from the groove opening. The two clamping plates 423 are made of rubber. By embedding the clamping plates 423 into the clamping slots, the clamping plates 423 seal the water storage shell 410 to prevent water from leaking from the chute. The water inlet pipe 420 can move inside the groove opening and the chute. During the movement of the water inlet pipe 420, the sealing plates 421 and the two clamping plates 423 are relatively long and wide, so that the sealing plates 421 always seal the groove opening and the clamping plates 423 always seal the chute.

[0038] like Figures 5-7As shown, in this embodiment, multiple support arms 411 are rotatably connected to both ends of any water storage shell 410. The multiple support arms 411 at the same end of any water storage shell 410 are arranged circumferentially. Rubber cylinders 412 are fixedly connected between the multiple support arms 411 at the same end of any water storage shell 410. Each rubber cylinder 412 has an open end, and multiple circular holes are opened at the other end of each rubber cylinder 412. Each fixed tube 431 is fixedly sleeved with an adjacent circular hole. Two movable rings 440 are slidably sleeved on the outer wall of any water storage shell 410. Multiple guide rods 441 are rotatably connected to the outer wall of each ring 440. Each movable ring 440 is close to both ends of the adjacent water storage shell 410. The multiple guide rods 441 on each movable ring 440 correspond one-to-one with the multiple support arms 411 at the end of the adjacent water storage shell 410. One end of each guide rod 441 is rotatably connected to the outer wall of the corresponding support arm 411. Multiple rebound springs 442 are fixedly connected between each movable ring 440 and the adjacent collar 422. Multiple pull ropes 443 are fixedly connected between each movable ring 440 and the adjacent collar 422.

[0039] In specific implementation, the central axis of the water storage shell 410 coincides with the central axis of the adjacent conduit 300. In any flushing mechanism 400, when the inlet pipe 420 is in its initial state, the collar 422 is located in the middle of the adjacent water storage shell 410, the support arms 411 at both ends of the water storage shell 410 are in a straight state, the two moving rings 440 are close to the ends of the adjacent support arms 411, and the two rubber cylinders 412 are in an unstretched state. The two spray shells 430 are respectively covered by the two rubber cylinders 412. When the user connects the water pipe to the inlet pipe 420 and pushes the inlet pipe 420 to slide along the groove opening... At this time, the inlet pipe 420 can pull one moving ring 440 synchronously via the pull rope 443, while the other moving ring 440 remains stationary due to the compression and contraction of the adjacent rebound spring 442 by the collar 422. This causes one moving ring 440 to move, pulling the adjacent support arm 411 synchronously via the adjacent guide rod 441. The rotating support arm 411 then stretches and expands the adjacent rubber cylinder 412, partially blocking the internal space of the conduit 300. This prevents the rubber cylinder 412 from obstructing the flow of sludge inside the conduit 300 and prevents the expanded rubber cylinder 412 from covering the adjacent water spray. The water is pumped into the shell 430, and then water is supplied to the shell. The water flows into the interior of the water spray shell 430 adjacent to the deployed rubber cylinder 412. The other water spray shell 430 is still covered by the adjacent rubber cylinder 412, and the rubber cylinder 412 adjacent to the other water spray shell 430 is not easily deformed by the pressure of the adjacent support arm 411. This allows the water to flow out from the nozzle on the individual water spray shell 430 and spread along the deployed rubber cylinder 412, causing the water to wash in the deployment direction of the adjacent rubber cylinder 412. The water flow forms a ring-shaped water flow along the deployed rubber cylinder 412, which then impacts the pipeline. The inner wall is flushed to improve the flushing effect of the water flow on the pipe. Since the flushing point is close to the blockage, the flushing effect is improved. The rubber cylinder 412 can be deployed to reduce the amount of sludge flowing in the conduit 300, thereby reducing the amount of sludge entering the blockage and improving the flushing effect of the water flow on the blockage. The direction of movement of the inlet pipe 420 near the blockage can be controlled to perform forward and reverse flushing treatment on the blockage. In actual use, soft isolation materials such as plastic film or rubber film can be wrapped around the two moving rings 440 to prevent sludge from contacting the rebound spring 442.

[0040] like Figures 8-9As shown, in this embodiment, a piston plate 450 is slidably sleeved inside any water spray shell 430. Multiple return springs 451 are fixedly connected between any piston plate 450 and one end of the interior of an adjacent water spray shell 430. Multiple insertion holes are opened at one end of any water spray shell 430. Multiple positioning rods 452 are fixedly connected to one side of any piston plate 450. Each positioning rod 452 is slidably sleeved with an adjacent insertion hole. An agitation rope 460 is provided between two adjacent flushing mechanisms 400. Fixed plates 461 are fixedly connected to both ends of any agitation rope 460. Each fixed plate 461 is fixedly connected to an adjacent positioning rod 452. A counterweight 462 is fixedly sleeved in the middle of any agitation rope 460.

[0041] In practice, initially, the agitator cable 460 is taut. When the water pump injects water into the inlet pipe 420, it uses an intermittent water injection method, so that when the water flows into the spray shell 430, the water pressure pushes the piston plate 450 to move, and then the water flows out from the spray head. At this time, the piston plate 450 drives the positioning rod 452 to move, so that the adjacent agitator cable 460 becomes slack from its original taut state. Then, when the water flows and impacts the silt, it will simultaneously impact the agitator cable 460, so that the agitator cable 460 and the counterweight 462 will move freely inside the adjacent connecting pipe 200 due to the impact of the water flow, which can guide the silt. After the water injection stops, the piston plate 450 resets under the action of the return spring 451 and straightens the agitator cable 460 again.

[0042] Example 2

[0043] Based on Example 1, a ring body is provided to facilitate fixing the position of the water inlet pipe 420.

[0044] like Figures 4-5 As shown, in this embodiment, a ring is fixedly connected to the sealing plate 421 located outside the adjacent conduit 300 on any water inlet pipe 420, and a threaded hole is opened on the outer wall of any conduit 300.

[0045] In practice, when the water inlet pipe 420 is not connected to the water pump, the ring body on the water inlet pipe 420 can be aligned with the threaded hole, and then a bolt can be screwed into the threaded hole after passing through the ring body to fix the position of the water inlet pipe 420, so that the two moving rings 440 can maintain their relative positions under the action of the spring spring 442.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
