Description

Technical Field

[0001] This invention relates to the field of dredging technology, specifically to a dredging suction device that utilizes ultrasonic vibration to assist in dredging and mud removal. Background Technology

[0002] With the rapid development of my country's shipping industry, infrastructure projects such as ports and waterways have flourished, leading to a growing demand for dredging vessels. Cutter suction dredgers utilize a rotating cutter head to loosen the soil on the riverbed or seabed, mixing water and mud into a slurry. This slurry is then sucked into the pump body through the suction pipe and transported to the discharge area through the discharge pipe. During operation, cutter suction dredgers integrate dredging, conveying, and unloading, achieving high production efficiency.

[0003] However, due to the high water content and viscosity of seabed silt, it is easy for silt to coat the cutter head and block the suction pipe channel during long-term use of the dredging device, thus affecting the dredging efficiency.

[0004] Therefore, in order to address the above problems, a dredging suction device that uses ultrasonic vibration to assist in dredging and mud removal is proposed. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by developing a dredging cutter suction device that utilizes ultrasonic vibration to assist in dredging and mud removal. This invention can remove silt and mud from the cutter surface when silt accumulates on the cutter during long-term use of the device, enabling the cutter to work efficiently and improving construction efficiency and quality.

[0006] To achieve the above objectives, the present invention employs the following technical solution: A dredging and desludge removal device using ultrasonic vibration-assisted dredging includes a housing. A bidirectional transmission assembly is installed inside the housing, connecting an inner rotating assembly and an outer rotating assembly, causing them to rotate in opposite directions. A fixed seat is fitted around the outer side of the inner rotating assembly and connected to the housing. An ultrasonic cleaning assembly is mounted on the fixed seat and contacts the inner rotating assembly. The inner rotating assembly includes an inner cutter head seat, and the outer rotating assembly includes an outer cutter head seat. The inner cutter head seat is located inside the outer cutter head seat and coaxially arranged. An inner reamer is installed outside the inner cutter head seat, and an outer shredder is installed outside the outer cutter head seat. Several sludge discharge ports are circumferentially opened around the outer cutter head seat. A sludge suction pipe is installed at the bottom of the housing, with its inlet end connected to the sludge discharge ports.

[0007] Preferably, the bidirectional transmission assembly includes a fixed rod, one end of which is mounted on the inner wall of the housing, and the other end of which is mounted on a planetary carrier. Multiple planetary gears are mounted on the planetary carrier, and these planetary gears surround the outer side of the central gear, with each planetary gear meshing with the central gear. A central shaft is coaxially mounted on the central gear, passing through the center of the inner cutter head seat. The end of the central shaft away from the central gear is connected to the outer rotating assembly, so that the inner and outer rotating assemblies rotate in opposite directions, resulting in better crushing of underwater silt and improving the practicality of the device.

[0008] Preferably, the ultrasonic cleaning assembly includes several ultrasonic generators, which are circumferentially arranged around one end of the fixed base near the inner blade disc base, and the vibrating ends of the ultrasonic generators are all in contact with the inner blade disc base. A bearing is sleeved on the outside of the fixed base, and the bearing is coaxially rotatably connected to the outer blade disc base. An air inlet is opened on the side wall of the fixed base, and an air inlet assembly is provided on the outside of the fixed base. The air inlet is connected to the air inlet assembly, which improves the working efficiency of the device.

[0009] Preferably, the inner rotating assembly also includes an inner gear rotating sleeve, which is coaxially arranged inside the fixed base. One end of the inner gear rotating sleeve is connected to the inner cutter head seat, and the other end is coaxially arranged with an outer gear ring. The outer gear ring is sleeved on the outside of the fixed rod and can drive the inner gear rotating sleeve to rotate. An internal gear is arranged on the inner wall of the inner gear rotating sleeve, and the internal gear meshes with the planetary gear, which improves the practicality of the device.

[0010] Preferably, the interior of the internal gear rotating sleeve is connected to the interior of the internal cutter head seat. Several vent holes are evenly spaced around the side wall of the internal gear rotating sleeve. The positions of the vent holes correspond to the positions of the air inlets, and the air inlets can communicate with the vent holes, which improves the stability of the device during use.

[0011] Preferably, the device also includes a power assembly, which includes a power component. The power component is located outside the fixed base, and a gear is coaxially mounted on the output end of the power component. The gear meshes with the external gear ring to drive the external gear ring to rotate, thereby improving the practicality of the device.

[0012] Preferably, the inner cutter head seat is conical, with a contact ring circumferentially arranged at the larger diameter end of the inner cutter head seat. The contact ring contacts the vibrating end of the ultrasonic generator. An annular step is also provided at the larger diameter end of the inner cutter head seat, with several sliding grooves evenly spaced circumferentially arranged on the annular step. The larger diameter end of the inner cutter head seat is coaxially sleeved on the outside of the inner gear rotating sleeve through the annular step, and the inner cutter head seat and the inner gear rotating sleeve are movably connected. A magnetic ring is arranged in the sliding groove and is slidably sleeved on the connecting post. One end of the connecting post is located at the end of the inner gear rotating sleeve, and the other end of the connecting post is provided with a magnetic block, which is slidably arranged in the sliding groove. The magnetic ring is located on the side of the magnetic block closer to the inner gear rotating sleeve, which is used to limit the magnetic block. The magnetic poles of the magnetic ring and the magnetic block on the side closer to each other repel each other, which improves the stability of the device.

[0013] Preferably, the air intake assembly includes an air pump, the air outlet of which is connected to the air inlet, and the air inlet of which is connected to the air inlet pipe for air input. Several exhaust holes are formed through the conical sidewall of the inner cutter head, and the exhaust holes are equally spaced along the spiral direction of the blade gap of the inner reamer. The air outlet of each exhaust hole is provided with a unidirectional foaming component, which improves the cleaning efficiency of the device.

[0014] Preferably, the one-way foaming assembly includes a one-way valve and a foamer. The one-way valve is connected to the interior of the inner cutter disc seat, and the air outlet of the one-way valve is connected to the air inlet of the foamer, which improves the practicality of the device.

[0015] Preferably, the external shredder assembly includes several toothed blades, one end of which is circumferentially and equally spaced on the outer cutter head seat, and the other end is mounted on the drill bit. The drill bit is connected to and coaxially mounted with the central shaft, which improves the stability of the device.

[0016] The effects described in the invention are merely those of the embodiments, and not all the effects of the invention. The above technical solution has the following advantages: 1. This invention sets up an ultrasonic cleaning component and contacts the vibrating end of the ultrasonic cleaning component with the inner blade plate seat to vibrate the inner reamer on the inner blade plate seat. This vibration of the inner reamer shakes off the sludge adhering to the surface of the inner reamer. At the same time, the high-speed vibration of the inner reamer in water also generates cavitation bubbles, which further clean the sludge on the surface of the inner reamer, avoiding affecting the operation of the device and improving the efficiency of the device during use. 2. By setting up a bidirectional transmission component, the inner and outer rotating components are driven to rotate in opposite directions, which improves the crushing effect on the bottom silt, avoids clogging of the suction pipe, and improves the working quality of the device. 3. By setting up an air intake component and a one-way foaming component, the present invention enables the inner blade holder to emit air bubbles towards the inner reamer and the outer shredding component. In conjunction with the ultrasonic cleaning component vibrating the inner reamer and the water, the air bubbles are broken by impact, thus cleaning the sludge on the surface of the inner reamer and the toothed blade, further improving the cleaning quality and the practicality of the device.

Detailed Implementation

[0020] 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.

[0021] like Figure 1-4 As shown, the present invention provides a technical solution: A dredging suction device utilizing ultrasonic vibration to assist in dredging and desludge removal includes a housing 1. A bidirectional transmission assembly is installed inside the housing 1, connecting an inner rotating assembly and an outer rotating assembly, causing them to rotate in opposite directions. A fixed seat 2 is fitted around the outer side of the inner rotating assembly and connected to the housing 1. An ultrasonic cleaning assembly is mounted on the fixed seat 2 and contacts the inner rotating assembly. The inner rotating assembly includes an inner cutterhead seat 17, and the outer rotating assembly includes an outer cutterhead seat 12. The cutter head seat 17 is located inside the outer cutter head seat 12 and is coaxially arranged. An inner reamer 18 is arranged on the outer side of the inner cutter head seat 17, and an outer shredding assembly is arranged on the outer side of the outer cutter head seat 12. Several mud discharge ports 6 are evenly spaced around the outer cutter head seat 12. A mud suction pipe 9 is arranged at the bottom of the outer shell 1. The feed end of the mud suction pipe 9 can communicate with the mud discharge port 6. The distance between two adjacent mud discharge ports 6 is smaller than the diameter of the mud suction pipe 9, so that the mud suction pipe 9 and the mud discharge port 6 are always in a connected state when the outer cutter head seat 12 rotates, thus avoiding blockage of the feed end of the mud suction pipe 9.

[0022] In this embodiment, the bidirectional transmission assembly includes a fixed rod 22. One end of the fixed rod 22 is disposed on the inner wall of the outer casing 1, and the other end of the fixed rod 22 is disposed on a planetary carrier 21. Multiple planetary gears 20 are disposed on the planetary carrier 21. The multiple planetary gears 20 surround the outer side of the central wheel 19, and all planetary gears 20 mesh with the central wheel 19. The outer side of the planetary gears 20 is also meshed with the inner rotating assembly. A central shaft 16 is coaxially disposed on the central wheel 19. The central shaft 16 passes through the center of the inner cutter head seat 17, and the end of the central shaft 16 away from the central wheel 19 is connected to the outer rotating assembly. The central shaft 16 and the center of the inner cutter head seat 17 are in movable contact. Preferably, an elastic ring is disposed at the contact position between the central shaft 16 and the inner cutter head seat 17 as a buffer to prevent damage to the central shaft 16 when the inner cutter head seat 17 vibrates. Through the meshing of the planetary gears 20 and the central wheel 19, the rotation directions of the inner rotating assembly and the outer rotating assembly are opposite, resulting in better crushing effect on the bottom silt, avoiding blockage of the suction pipe, and improving the safety of the device.

[0023] In this embodiment, the ultrasonic cleaning assembly includes several ultrasonic generators 23, which are evenly arranged around one end of the fixed base 2 near the inner cutter disc seat 17. The vibrating ends of the ultrasonic generators 23 are all in contact with the inner cutter disc seat 17. A bearing 14 is sleeved on the outside of the fixed base 2, and the bearing 14 is coaxially rotatably connected to the outer cutter disc seat 12. An air inlet 10 is opened on the side wall of the fixed base 2, and an air inlet assembly is provided on the outside of the fixed base 2. The air inlet 10 is connected to the air inlet assembly. The ultrasonic generators 23 contact the side wall of the inner cutter disc seat 17, and the vibration of the ultrasonic generators 23 causes the inner cutter disc seat 17 to vibrate. The ultrasonic vibration is then transmitted from the inner cutter disc seat 17, forming a large number of bubbles on the inner cutter disc seat 17. The cavitation caused by the bursting of the bubbles is used to clean the sludge on the surface of the inner reamer 18, thereby improving the working efficiency of the device.

[0024] In this embodiment, the inner rotating assembly further includes an inner gear rotating sleeve 3, which is coaxial with the fixed base 2. The internal gear rotating sleeve 3 is installed inside the fixed base 2. One end is connected to the inner cutter head seat 17, and the other end is coaxially provided with an external gear ring 32. The external gear ring 32 is sleeved on the outside of the fixed rod 22, and the external gear ring 32 can drive the internal gear rotating sleeve 3 to rotate. An internal gear is provided on the inner wall of the internal gear rotating sleeve 3. The internal gear meshes with the planetary gear 20, so that the internal gear rotating sleeve 3 acts as the driving member to drive the central wheel 19 to rotate in the opposite direction, which improves the practicality of the device.

[0025] In this embodiment, the interior of the internal gear rotating sleeve 3 is connected to the interior of the internal cutter head seat 17. A plurality of vent holes 11 are evenly spaced around the side wall of the internal gear rotating sleeve 3. The positions of the vent holes 11 correspond to the positions of the air inlets 10, and the air inlets 10 can communicate with the vent holes 11. The distance between two adjacent vent holes 11 is smaller than the diameter of the air inlets 10, so that the air inlets 10 and the vent holes 11 are always in a connected state when the internal gear rotating sleeve 3 rotates, so as to ventilate the interior of the internal gear rotating sleeve 3 and the interior of the internal cutter head seat 17, thereby improving the stability of the device during use.

[0026] In this embodiment, a power assembly is also included, including a power component 8. The power component 8 is a motor and is located on the outside of the fixed base 2. A gear 7 is coaxially mounted on the output end of the power component 8. The gear 7 meshes with the external gear ring 32. A through hole is provided on the fixed base 2 at the position corresponding to the meshing position of the gear 7 and the external gear ring 32 to facilitate power transmission. The power assembly is used to drive the external gear ring 32 to rotate, providing power for the device to crush sludge and improving the practicality of the device.

[0027] In this embodiment, the inner cutter head seat 17 is tapered. A contact ring 30 is circumferentially arranged at the larger diameter end of the inner cutter head seat 17, and the contact ring 30 contacts the vibrating end of the ultrasonic generator 23. An annular step 31 is also provided at the larger diameter end of the inner cutter head seat 17. Several sliding grooves 27 are circumferentially spaced at equal intervals on the annular step 31. The larger diameter end of the inner cutter head seat 17 is coaxially sleeved on the outside of the internal gear rotating sleeve 3 via the annular step 31, and the inner cutter head seat 17 and the internal gear rotating sleeve... The three sections are connected by a sliding groove 27. A magnetic ring 29 is installed in the sliding groove 27 and is slidably sleeved on the connecting post 26. One end of the connecting post 26 is set at the end of the internal gear rotating sleeve 3, and the other end of the connecting post 26 is set with a magnetic block 28. The magnetic block 28 is slidably set in the sliding groove 27. The magnetic ring 29 is located on the side of the magnetic block 28 that is close to the internal gear rotating sleeve 3, which is used to limit the magnetic block 28. The magnetic poles of the magnetic ring 29 and the magnetic block 28 on the side that are close to each other repel each other, which improves the practicality of the device.

[0028] In this embodiment, the starting power component 8 drives the gear 7 to rotate, which in turn drives the outer gear ring 32 meshing with it to rotate. The outer gear ring 32 drives the coaxially connected inner gear rotating sleeve 3 to rotate. Several connecting posts 26 provided on the inner gear rotating sleeve 3 radially limit the rotation of the inner gear rotating sleeve 3 through a sliding groove 27, enabling the inner gear rotating sleeve 3 to drive the inner cutter head 17 to rotate, thereby driving the inner reamer 18 to rotate. At the same time, the rotation of the inner gear rotating sleeve 3 drives several planetary gears 20 to rotate on the planet carrier 21. The planet carrier 21 remains stationary due to the connection between the fixed rod 22 and the outer shell 1. The planetary gears 20 only rotate on their own axis. The rotation of the planetary gears 20 drives the central wheel 19 to rotate. The central wheel 19 drives the outer cutter head 12 to rotate through the central shaft 16 and the outer shredder assembly. Through the inner gear rotating sleeve 3 and several connecting posts 26 provided on the inner gear rotating sleeve 3, the inner cutter head 17 rotates, thereby driving the inner cutter head 18 to rotate. The planetary gear 20 and the central gear 19 cooperate, and the rotation direction of the outer cutter head 12 is opposite to that of the inner cutter head 17. At the same time, the inner cutter head 17 can slide at the end of the inner tooth rotating sleeve 3. The magnetic block 28 and the magnetic ring 29 set in the sliding groove 27 initially repel each other under the action of magnetic force. When the axial vibration generated by the ultrasonic generator 23 causes the inner cutter head 17 to move away from the inner tooth rotating sleeve 3 in the axial direction, the magnetic block 28 and the magnetic ring 29 move closer due to the vibration. The magnetic block 28 slides closer to the magnetic ring 29 in the sliding groove 27, and then moves away again under the repulsive action of the magnetic block 28 and the magnetic ring 29, thereby causing the inner cutter head 17 to move closer to the inner tooth rotating sleeve 3. This process repeats, so that the inner cutter head 17 and the inner reamer 18 act as oscillators to generate cavitation bubbles, which improves the cleaning quality of the device.

[0029] In this embodiment, the air intake assembly includes an air pump 4. The air outlet of the air pump 4 is connected to the air inlet 10, and the air inlet of the air pump 4 is connected to the air inlet pipe 5. The air inlet pipe 5 is used for air input. A plurality of exhaust holes 24 are formed through the conical sidewall of the inner cutter head 17. The plurality of exhaust holes 24 are equally spaced along the spiral direction of the blade gap of the inner reamer 18. The air outlet of each exhaust hole 24 is provided with a one-way foaming assembly 25. The one-way foaming assembly 25 includes a one-way valve and a foamer. The one-way valve is connected to the interior of the inner cutter head 17, and the air outlet of the one-way valve is connected to the air inlet of the foamer. The air pump 4 delivers air... Air is introduced into the air inlet 10, and several vent holes 11 remain connected to the air inlet 10 during rotation, allowing air to enter the interior of the inner cutter head 17. The air is then discharged through several exhaust holes 24. The exhaust holes 24 are equipped with a one-way valve and a foamer. The one-way valve is used to prevent external mud and water from entering, and the foamer is used to split the air into several small bubbles. These bubbles, in conjunction with those generated by vibration, wash the surfaces of the inner reamer 18 and the toothed blade 13. The cavitation phenomenon caused by the bursting of the bubbles separates the adhering sludge from the surfaces of the inner reamer 18 and the toothed blade 13, achieving a cleaning effect.

[0030] In this embodiment, the external shredding assembly includes several toothed blades 13. One end of each toothed blade 13 is circumferentially and equally spaced on the outer cutter head seat 12, and the other end is mounted on the drill bit 15. The drill bit 15 is connected to and coaxially mounted with the central shaft 16, and a gap is provided between two adjacent toothed blades 13 to facilitate the crushing of sludge and allow the sludge to enter the conical space enclosed by the toothed blades 13. The mixture of sludge and water is then sucked out through the sludge discharge port 6 and the sludge suction pipe 9.

[0031] Working principle: First, the device of this invention is placed underwater, and the discharge end of the suction pipe 9 is connected to the suction pump. The device is started, and the bidirectional transmission component of the device drives the inner cutter head 17 and the outer cutter head 12 to rotate respectively. The inner cutter head 17 and the outer cutter head 12 rotate in opposite directions, and respectively drive the inner reamer 18 and the outer shredding component to rotate, which is beneficial to the crushing of seabed silt. At the same time, the ultrasonic cleaning component is started. The ultrasonic cleaning component vibrates the inner reamer 18, and works with the air intake component and the one-way foaming component 25 to surface the inner reamer 18. Remove the sludge adhering to the surface of the shredder and outer shredder assembly to prevent sludge from clogging the shredder and the suction tube during long-term use. Specifically, start the power unit 8, which drives the gear 7 to rotate, thereby causing the outer gear ring 32, which meshes with the gear 7, to rotate around the axis of the fixed rod 22. The outer gear ring 32 drives the inner gear rotating sleeve 3 to rotate, which in turn drives the inner cutter head seat 17 to rotate. The inner side of the inner gear rotating sleeve 3 meshes with the planetary gear 20. Since the planetary gear 20 is fixed on the planet carrier 21, the planetary gear 20 rotates on its own. The movement of the central wheel 19 causes the central wheel 19 to rotate in the opposite direction to the rotation of the internal gear rotating sleeve 3. The central wheel 19 drives the central shaft 16 to rotate, which in turn drives the drill bit 15 to rotate. The drill bit 15 drives the toothed cutting blade 13 and the outer cutter head 12 to rotate. At the same time, the suction pipe 9 extracts the mud-water mixture after the device has loosened the silt through the discharge port 6. Simultaneously, the air pump 4 is started. The air pump 4 draws air through the air inlet pipe 5 and introduces the air into the internal gear rotating sleeve 3 and the inner cutter head 12 through the air inlet 10 and the vent 11. Inside the device 7, the air is discharged outward through the exhaust hole 24 on the side wall of the inner cutter head 17. The air passes through a one-way valve so that the air can only flow outward, and then enters the foamer. The foamer divides the air into several individual bubbles that are discharged outward. This, combined with the vibration of the ultrasonic generator 23, causes the inner cutter head 17 to vibrate. The inner cutter head 17 drives the inner reamer 18 to vibrate, which in turn causes the bubbles to break upon impact. This, combined with the vibration of the inner reamer 18 itself, generates cavitation bubbles, which clean the sludge adhering to the inner reamer 18 and the toothed blade 13, thus improving the working efficiency of the device.
