Description

Technical Field

[0001] This invention belongs to the field of anti-siltation dredging technology, specifically an anti-siltation dredging device for port channels. Background Art

[0002] Port channels are waterways specifically designed for ship navigation. Their core function is to ensure the safe and efficient entry and exit of ships, and they are also a critical infrastructure for maritime logistics. Frequent ship traffic increases the velocity and impact of the water flow, leading to the accumulation of silt and sediment at river mouths. This indirectly affects the passage of large ships. When ships reach silted areas, navigation capacity decreases, and insufficient water depth can cause ships to run aground or require unloading. To prevent siltation, port officials regularly organize dredging teams to carry out dredging work using dredging vessels, mud dredgers, or vessels equipped with sand pumps. However, this would remove silt and larger stones from the riverbed, and silt and stones have completely different uses. In subsequent treatment, it may be necessary to spend additional time and money to remove the stones from the silt. Furthermore, the regular cleaning plan would require time to formulate each cleaning plan, which would consume a lot of manpower, material resources, and financial resources, making the project very complicated.

The top of the diversion tubes is connected to a transfer box, and the transfer box is equipped with an independent pipe for discharging sludge outward. The cylindrical storage device has a set of slots circumferentially arranged on the lower circumference of the device. A set of guide tubes is driven and connected to the power assembly. A storage ring is arranged inside the guide tubes. The power assembly drives the guide assembly to draw water and spray it into the storage ring. A set of inclined slots is arranged circumferentially on the side of the storage ring, with the ends of the slots facing the central axis of the storage ring.

[0005] Preferably, the positioning component includes a protective box and a second carrier plate. The protective box and the second carrier plate are connected by a set of positioning cylinders arranged at equal angles in a circumferential direction. The top of the positioning cylinder is designed to be open, allowing a steel pipe to pass through the positioning cylinder and be driven into the riverbed. The cylindrical storage device is fixed to the top of the second carrier plate.

[0006] Preferably, the power assembly includes a motor fixed inside the protective box, a bracket is driven to the output shaft of the motor, the top of the bracket is fixedly connected to the guide tube through a guide plate, and the output shaft of the motor is driven to the screw conveyor shaft.

[0007] Preferably, the protective box includes a waterproof box; The motor is fixed inside the waterproof box, and the waterproof box is movably connected to the bearing plate by a limiting ring, and the bracket passes through the limiting ring.

[0008] Preferably, the positioning component further includes a support connected between the waterproof box and the carrier plate; The support includes a support bucket fixed to a waterproof box and a receiving ring fixed to the bottom of a bearing plate. The support bucket and the receiving ring are movably connected by a limiting ring, and the bracket passes through the limiting ring.

[0009] Preferably, the power assembly further includes a sun gear that is connected to the output shaft of the motor, and a set of planetary gears are arranged circumferentially on one of the bearing disks, the planetary gears meshing with the sun gear; The flow guiding assembly includes a flow guiding pipe fixed on the second bearing disk and corresponding to the planetary gear, and a turbine located inside the flow guiding pipe is drivenly connected to the top of the planetary gear.

[0010] Preferably, the flow guiding assembly further includes an energy storage box, which is movably snapped between the second support plate and the first support plate. A sealing plate is movably snapped onto the inner wall of the energy storage box, and each of the flow guiding pipes is connected between the sealing plate and the energy storage box through a guide pipe. The guide plate has an aperture that communicates with the inside of the energy storage box, and the other end of the aperture is connected to the inside of the storage ring.

[0013] Preferably, the cylindrical memory is fixedly mounted on the second support member, and the output shaft of the motor movably passes through the second support member.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a combination of power components and dredging components. The power component drives the spiral conveyor shaft to rotate, and the grooves in the spiral blades on the shaft reduce the downward sliding tendency of stones when they fall onto the blades. The stones are guided upward by the spiral conveyor shaft, while the silt driven upward by the shaft falls downward through the mesh-like spiral blades. That is, the silt is always located at the bottom inside the cylindrical storage container, while the stones are stuck in the mesh, thus separating the two. It is important to note that the top of the spiral blades in the spiral conveyor shaft is not flush with the top of the cylindrical storage container, so the stones eventually accumulate at the top of the spiral conveyor shaft. This reduces the cost of subsequent separation of sand and silt, and also reduces the time, labor, and economic costs of determining the specific location of silt accumulation, making dredging work simpler and more convenient. This invention, through the coordination of various structures, allows the motor output shaft to drive the planetary gears to rotate via the sun gear. The water pressure generated by the turbine rotation increases simultaneously, and water enters the storage ring through the guide pipe, energy storage box, and holes in the guide plate, causing water to be ejected from the end of the storage ring. The impact force of the water flow can guide the surrounding silt into the interior of the cylindrical storage device. Silt and other debris near the device can also be impacted into the interior of the cylindrical storage device by the water pressure, thereby reducing the area of ​​silt accumulation.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figures 1 to 8 As shown, the present invention provides a dredging device for preventing siltation in port channels, comprising: Positioning component 1 fixed to the riverbed and power component 2 installed inside the positioning component 1; Dredging component 3 is installed on top of positioning component 1; The flow guide component 4 is installed on the positioning component 1; The dredging assembly 3 includes a cylindrical storage 31 fixed on the top of the positioning assembly 1, and a spiral conveying shaft 32 is driven to the power assembly 2. The spiral conveyor shaft 32 is located inside the cylindrical memory 31. The upper half of the spiral conveyor shaft 32 has a mesh design for the threaded blades, and the lower half has equidistant grooves. The lower end of the cylindrical memory 31 is connected to a group of diversion tubes 33 of the circumferential array. The top of the diversion tubes 33 is connected to a transfer box 34. The transfer box 34 is provided with an independent pipe for discharging sludge outward. A set of slots is arranged around the lower periphery of the cylindrical storage 31. A set of guide tubes 36 are connected to the power assembly 2. A storage ring 37 is arranged inside the guide tubes 36. The power assembly 2 drives the guide assembly 4 to draw water and spray it into the storage ring 37. A set of inclined slots is arranged around the side of the storage ring 37, and the ends of the slots face the central axis of the storage ring 37.

[0019] The above-mentioned approach involves first cleaning up the silt and other debris on the riverbed, then placing the device on the riverbed where silt tends to accumulate and securing it in place. Then the power component 2 is activated, which drives the flow guiding component 4 to draw water from the outside and spray it into the storage ring 37. Finally, the water is sprayed outward through the slot on the side of the storage ring 37. When the ship moves and guides the water flow to carry the silt to the periphery of the device, the water flow sprayed on the slot of the storage ring 37 will guide the silt or the stones mixed in it to move outward and backward towards the cylindrical storage 31. Finally, the silt and stones can enter the interior of the cylindrical storage 31 through the slot on the lower outer periphery of the cylindrical storage 31. During this period, the silt and stones will not accumulate excessively. The power unit 2 also drives the guide tube 36 to rotate, which means that the water jet from the storage ring 37 is not limited to a certain axis, but rotates around the cylindrical storage 31, which greatly reduces the range of sludge accumulation.

[0020] The power unit 2 also drives the spiral conveyor shaft 32 to rotate. When too much silt and stones are retained inside the cylindrical storage 31, the grooves of the spiral blades on the spiral conveyor shaft 32 can reduce the downward tendency of the stones when they fall on the blades. However, the silt is always located at the bottom inside the cylindrical storage 31. When the spiral conveyor shaft 32 rotates, the stones can rise, while the silt that may be driven to rise by the spiral conveyor shaft 32 will fall downward through its grid-like spiral blades. That is, the silt is always located at the bottom inside the cylindrical storage 31, while the stones are stuck in the grid and the two are separated. It should be noted that the top of the spiral blades in the spiral conveyor shaft 32 is not flush with the top of the cylindrical storage 31, so the stones will eventually accumulate at the top of the spiral conveyor shaft 32. When the silt and stones inside the cylindrical storage 31 need to be cleaned, the input pipe of the sand pump is connected to the independent pipe at the top of the transfer box 34. At this time, the silt inside the cylindrical storage 31 can be cleaned by the sand pump through the diversion pipe 33 and the transfer box 34. The stones at the top of the spiral conveyor shaft 32 can be cleared by an excavator, which greatly reduces the cost of subsequent separation of sand and silt, and also reduces the time, labor and economic costs of determining the specific location of silt accumulation, making dredging work simpler and more convenient. However, the cleaning cycle needs to be determined based on the actual situation, and there is no fixed interval between each cleaning.

[0021] like Figures 1-4 and Figure 8As shown, the positioning component 1 includes a protective box 11 and a second carrier plate 14. The protective box 11 and the second carrier plate 14 are connected by a set of positioning cylinders 16 arranged at equal angles in a circumferential direction. The top of the positioning cylinder 16 is designed to be open, and the steel pipe can pass through the positioning cylinder 16 and be driven into the riverbed. The cylindrical memory 31 is fixed to the top of the second carrier plate 14.

[0022] Using the above method: the device is placed on the riverbed first. After the position is determined, the steel pipe is inserted through the positioning cylinder 16 and driven into the riverbed. At this time, the device is fixed on the riverbed to prevent the device from drifting with the water flow. However, it should be noted that the above-mentioned fixing device scheme is not the only one. In actual working conditions, it can be changed to a fixing scheme that is more suitable for the actual working environment.

[0023] The power assembly 2 includes a motor 21 fixed inside the protective box 11. A bracket 23 is driven to the output shaft of the motor 21. The top of the bracket 23 is fixedly connected to the guide tube 36 through a guide plate 24. The output shaft of the motor 21 is driven to the screw conveyor shaft 32.

[0024] Using the above scheme: the output shaft of motor 21 drives the screw conveyor shaft 32 into working state. At the same time, the output shaft of motor 21 will also drive the guide plate 24 and the guide cylinder 36 on it to rotate simultaneously through the bracket 23. The storage ring 37 guides the sludge into the cylindrical storage 31 through the sprayed water flow, thereby reducing the range of sludge accumulation.

[0025] like Figures 1-8 As shown, the protective box 11 includes a waterproof box 111; The motor 21 is fixed inside the waterproof box 111. The waterproof box 111 is connected to the bearing plate 113 by a limiting ring 112. The bracket 23 passes through the limiting ring 112.

[0026] With the above solution: when the bracket 23 is driven to rotate by the motor 21, it drives the limit ring 112 to rotate at the same time. However, external mud and sand cannot enter the interior of the waterproof box 111 and come into contact with the motor 21, thereby reducing the impact of external factors on the operation of the motor 21 and extending the service life of the motor 21.

[0027] like Figures 1-8 As shown, the positioning component 1 also includes a support 12 connected between the waterproof box 111 and the carrier plate 113; The support 12 includes a support barrel 121 fixed on the waterproof box 111 and a receiving ring 123 fixed on the bottom of the bearing plate 113. The support barrel 121 and the receiving ring 123 are movably connected by a limiting ring 122, and the bracket 23 passes through the limiting ring 122.

[0028] The above scheme is adopted: when the bracket 23 rotates, the limiting ring 122 is also driven to rotate. However, it should be noted that this does not affect the overall support of the support 12 for the bearing plate 113. Under long-term operation, it can better ensure that the weight of the silt and sand inside the flow guiding component 4 and the cylindrical storage 31 compresses the bearing plate 113 to bend, and further extends the service life of the device.

[0029] like Figures 1-8 As shown, the power assembly 2 also includes a sun gear 22 that is connected to the output shaft of the motor 21, and a set of planetary gears 25 are arranged circumferentially on the bearing disk 113, with the planetary gears 25 meshing with the sun gear 22; The flow guiding assembly 4 includes a flow guiding pipe 41 fixed on the support plate 2 14 and corresponding to the planetary gear 25. The top of the planetary gear 25 is connected to a turbine 411 located inside the flow guiding pipe 41.

[0030] The flow guiding component 4 also includes an energy storage box 44, which is movably snapped between the second carrier plate 14 and the first carrier plate 113. A sealing plate 43 is movably snapped onto the inner wall of the energy storage box 44, and each flow guiding pipe 41 is connected between the sealing plate 43 and the energy storage box 44 through a guide pipe 42. The guide plate 24 has an aperture that communicates with the inside of the energy storage box 44, and the other end of the aperture is connected to the inside of the storage ring 37.

[0031] Using the above scheme: the output shaft of motor 21 drives planetary gear 25 to rotate through sun gear 22. Since the number of teeth of sun gear 22 is greater than the number of teeth of planetary gear 25, the rotational speed of planetary gear 25 is greater than that of sun gear 22, thereby increasing the water pressure generated by the rotation of turbine 411. Water enters the storage ring 37 through the guide pipe 42, energy storage box 44 and the aperture on guide plate 24, so that water is sprayed out from the end of storage ring 37. The impact force of the water flow can guide the surrounding silt into the interior of cylindrical storage 31 and reduce the problem of silt accumulation. When the guide plate 24 is driven to rotate, the energy storage box 44 rotates at the same time. However, since the guide pipe 42 is connected to the energy storage box 44 through the sealing plate 43, the water can also flow smoothly. Furthermore, during the rotation of the guide tube 36, the guide pipe 41 will not always be in the stroke of the storage ring 37 spray, thus not having too much impact on it.

[0032] like Figures 5-7 As shown, a metal filter screen is provided at the top of the guide pipe 41, and the top of the guide pipe 41 is higher than the end of the guide cylinder 36.

[0033] With the above solution, when the turbine 411 draws water from above the guide pipe 41, the metal filter on the guide pipe 41 can effectively reduce the entry of impurities into the interior of the guide pipe 41, thereby interfering with the rotation of the turbine 411 and causing unnecessary wear. Furthermore, when the top of the guide pipe 41 is higher than the end of the guide cylinder 36, the water sprayed by the storage ring 37 guides the sludge to move, which greatly reduces the probability of sludge drifting to the top of the guide pipe 41, further preventing the possibility of the metal filter being blocked.

[0034] like Figures 1-8 As shown, the second carrier plate 14 includes a first carrier 141 and a second carrier 142. The guide pipe 41 is fixed on the second carrier 142. The first carrier 141 is connected to the guide pipe 41 through the positioning plate 15. The guide plate 24 is located between the first carrier 141 and the second carrier 142.

[0035] The cylindrical memory 31 is fixedly mounted on the second support member 142, and the output shaft of the motor 21 is movably passed through the second support member 142.

[0036] The above scheme is adopted: Since the first carrier 141 is connected to the waterproof box 111 through the positioning cylinder 16, and the steel pipe passes through the positioning cylinder 16 and is driven into the riverbed, the first carrier 141 is in a fixed state. The first carrier 141 is also connected to the guide pipe 41 through the positioning plate 15. The guide pipe 41 is fixed to the second carrier 142. Therefore, the second carrier 142 and its structure are also in a fixed state. Only when the cylindrical storage 31 is fixed can the spiral conveying shaft 32 rotate to transport the sand and gravel inside the cylindrical storage 31 to its top, thereby ensuring the smooth operation of the device.

[0037] Working principle and usage process of this invention: First, the silt and other debris on the riverbed are cleared. Then, the device is placed on the riverbed where silt is more likely to accumulate. The steel pipe is inserted through the positioning cylinder 16 and driven into the riverbed. At this time, the device is fixed on the riverbed. The output shaft of motor 21 drives planetary gear 25 to rotate through sun gear 22. The water pressure generated by the rotation of turbine 411 increases, and water enters the storage ring 37 through the guide pipe 42, energy storage box 44 and the aperture on guide plate 24, so that water is sprayed out from the end of storage ring 37. The impact force of the water flow can guide the surrounding silt into the interior of cylindrical storage 31. Motor 21 drives guide plate 24 and guide tube 36 on it to rotate simultaneously via bracket 23, and storage ring 37 guides silt into cylindrical storage 31 through jet water flow; Motor 21 drives the spiral conveyor shaft 32 to rotate. When too much silt and stones are retained inside the cylindrical storage 31, the grooves of the spiral blades on the spiral conveyor shaft 32 can reduce the tendency of sand and gravel to slide downwards when stones fall on the blades. When the spiral conveyor shaft 32 rotates, the stones can rise, while the silt that may be driven to rise by the spiral conveyor shaft 32 will fall downwards through its grid-like spiral blades. The silt is always located at the bottom inside the cylindrical storage 31, while the stones are stuck in the grid, and the two are separated. It should be noted that the top of the spiral blades in the spiral conveyor shaft 32 is not flush with the top of the cylindrical storage 31, so the stones will eventually accumulate at the top of the spiral conveyor shaft 32. When the silt and stones inside the cylindrical storage 31 need to be cleaned, the input pipe of the sand pump is connected to the independent pipe at the top of the transfer box 34. At this time, the silt inside the cylindrical storage 31 can be cleaned by the sand pump through the diversion pipe 33 and the transfer box 34, while the stones at the top of the screw conveyor shaft 32 can be cleaned by an excavator.
