Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterway cleaning technology, and in particular to a dredging and cleaning mechanism for port waterways. Background Technology
[0002] Dredging and cleaning of port and waterway silt is crucial for ensuring the smooth flow of traffic in ports and waterways. Currently, during silt removal, it is impossible to separate the water from the silt, which severely affects the amount of silt that can be carried by ships. This leads to an increase in the number of times silt needs to be removed from ships, resulting in longer dredging periods and increased dredging costs.
[0003] A prior art patent application with publication number CN 222390536 U discloses a dredging and sludge removal device for waterways. The device uses a conveying unit to transport sludge into a guide pipe. Then, a second solenoid valve is opened, allowing the sludge to pass through the guide pipe into a container. Once the container is full, the second solenoid valve is closed. A first cylinder then moves a pressing plate, compressing the sludge and causing water to be discharged through multiple permeable holes. After the water is discharged, the first cylinder returns the pressing plate to its original position, and the first solenoid valve is opened again, allowing the sludge to be discharged from the outlet pipe. After discharge, the first solenoid valve is closed, and the above operation is repeated to separate water from subsequent sludge. This process removes water from the sludge, increasing the sludge carrying capacity of the vessel, reducing the frequency of sludge removal, and lowering the cost of waterway dredging.
[0004] However, in the existing technology, the device can only clean the silt at the same depth. When the channel is deep, the device cannot clean the silt at the bottom of the channel, resulting in poor silt removal effect. Utility Model Content
[0005] The purpose of this utility model is to provide a dredging and cleaning mechanism for port channels, which aims to solve the problem that in the prior art, the device can only clean silt at the same depth, and when the channel is deep, the device cannot clean the silt at the bottom of the channel, resulting in poor silt cleaning effect.
[0006] To achieve the above objectives, this utility model provides a port channel dredging and cleaning mechanism, including a hull and a cleaning mechanism. The cleaning mechanism includes an installation plate, a threaded rod, a threaded cylinder, a limiting component, a mounting frame, a pressure pump, a delivery pipe, and a storage component. The installation plate is fixedly connected to the hull and located at one end of the hull. The threaded rod is rotatably connected to the installation plate and extends below the installation plate. The threaded rod is threadedly connected to the threaded cylinder and located inside the threaded cylinder. The limiting component is located below the installation plate. The mounting frame is fixedly connected to the threaded cylinder and located below the threaded cylinder. The pressure pump is fixedly connected to the hull. One end of the delivery pipe is fixedly connected to and communicates with the input end of the pressure pump. The delivery pipe is fixedly connected to the mounting frame and passes through the mounting frame.
[0007] The limiting component includes a mounting cylinder and two retaining strips. The threaded cylinder has two retaining grooves, which are respectively located at both ends of the threaded cylinder. The mounting cylinder is fixedly connected to the mounting plate, and the threaded cylinder and the threaded rod are located inside the mounting cylinder. The two retaining strips are fixedly connected to both ends of the mounting cylinder, and the two retaining strips are slidably connected to the threaded cylinder and are respectively located in the two retaining grooves.
[0008] The storage assembly includes a connecting pipe, a storage tank, and a drainage kit. The storage tank is fixedly connected to the hull and located above the hull. One end of the connecting pipe is fixedly connected to and communicates with the output end of the pressure pump. The other end of the connecting pipe extends into the storage tank. The drainage kit is disposed inside the storage tank.
[0009] The drainage kit includes multiple partitions and a drain pipe. The partitions are fixedly connected to the storage box and divide the interior of the storage box into multiple spaces. The drain pipe is fixedly connected to one end of the storage box and is located above the storage box.
[0010] The cleaning mechanism further includes a mounting ring and multiple separator rods. The mounting ring is fixedly connected to the end of the delivery pipe away from the pressure pump, and the multiple separator rods are fixedly connected to the mounting ring and located inside the mounting ring.
[0011] This utility model discloses a dredging and cleaning mechanism for port channels. When using this device to clean channel silt, rotating the threaded rod causes the threaded cylinder to move downwards until one end of the conveying pipe extends to the bottom of the channel and is inserted into the silt. The pressure pump is then activated, drawing the silt into the conveying pipe and collecting it through the storage component. This process cleans the channel silt. The height of the conveying pipe inlet can be adjusted to clean silt at different depths, thereby improving the effectiveness of channel silt cleaning. Attached Figure Description

[0020] This utility model provides a dredging and cleaning mechanism for port channels, including a hull 101 and a cleaning mechanism. The cleaning mechanism includes a mounting plate 102, a threaded rod 103, a threaded cylinder 104, a limiting assembly, a mounting frame 110, a pressure pump 108, a delivery pipe 109, and a storage assembly. The limiting assembly includes a mounting cylinder 105 and two retaining strips 106. The threaded cylinder 104 has two retaining grooves 107. The storage assembly includes a connecting pipe 113, a storage tank 114, and a drainage kit. The drainage kit includes multiple partitions 115 and a drainage pipe 116.
[0021] In this embodiment, the mounting plate 102 is fixedly connected to the hull 101 and located at one end of the hull 101. The threaded rod 103 is rotatably connected to the mounting plate 102 and extends below the mounting plate 102. The threaded rod 103 is threadedly connected to the threaded cylinder 104 and located inside the threaded cylinder 104. The limiting component is located below the mounting plate 102. The mounting bracket 110 is fixedly connected to the threaded cylinder 104 and located below the threaded cylinder 104. The pressure pump 108 is fixedly connected to the hull 101. One end of the delivery pipe 109 is fixedly connected to and communicates with the input end of the pressure pump 108. The delivery pipe 109 is connected to... The mounting bracket 110 is fixedly connected and extends through the device. When cleaning channel silt using this device, the threaded rod 103 is rotated, causing the threaded cylinder 104 to move downwards until one end of the conveying pipe 109 extends to the bottom of the channel. One end of the conveying pipe 109 is inserted into the silt. The pressure pump 108 is then activated, drawing the silt into the conveying pipe 109 and collecting it through the storage component. This process cleans the channel silt. The height of the inlet of the conveying pipe 109 can be adjusted to clean silt at different depths, thereby improving the effectiveness of channel silt cleaning.
[0022] Furthermore, the two slots 107 are respectively disposed at both ends of the threaded cylinder 104, the mounting cylinder 105 is fixedly connected to the mounting plate 102, and the threaded cylinder 104 and the threaded rod 103 are located inside the mounting cylinder 105. The two retaining strips 106 are respectively fixedly connected to both ends of the mounting cylinder 105, and the two retaining strips 106 are slidably connected to the threaded cylinder 104 and are respectively located in the two slots 107.
[0023] In this embodiment, when controlling the inlet of the conveying pipe 109 to move up and down, the threaded rod 103 is rotated. The threaded rod 103 drives the threaded cylinder 104 and the inlet of the conveying pipe 109 to move up and down. The two retaining strips 106 on both sides of the mounting cylinder 105 slide in the two retaining grooves 107 respectively, which play a limiting and guiding role in the movement of the threaded cylinder 104 and the conveying pipe 109, ensuring that the conveying pipe 109 will not rotate during the movement.
[0024] Furthermore, the storage tank 114 is fixedly connected to the hull 101 and located above the hull 101. One end of the connecting pipe 113 is fixedly connected to the output end of the pressure pump 108 and is in communication with it. The other end of the connecting pipe 113 extends into the storage tank 114. The drainage kit is disposed in the storage tank 114.
[0025] Furthermore, multiple partitions 115 are fixedly connected to the storage box 114, dividing the interior of the storage box 114 into multiple spaces. The drain pipe 116 is fixedly connected to one end of the storage box 114 and is located above the storage box 114.
[0026] In this embodiment, the sludge is transported to the storage tank 114 through the connecting pipe 113. The arrangement of multiple partitions 115 can prevent the sludge entering the storage tank 114 from causing large disturbances, keeping the sludge in a relatively calm state. At this time, the sludge and water will separate into layers. When the sludge is about to fill the storage tank 114, the water above the sludge is discharged from the storage tank 114 through the drain pipe 116, so that as much sludge as possible can be collected in the storage tank 114.
[0027] Furthermore, the mounting ring 111 is fixedly connected to the end of the delivery pipe 109 away from the pressure pump 108, and the plurality of the separator rods 112 are fixedly connected to the mounting ring 111 and located inside the mounting ring 111.
[0028] In this embodiment, multiple separator rods 112 separate the inlet of the conveying pipe 109, preventing larger stones, garbage, and other debris from being sucked into the conveying pipe 109, ensuring that the conveying pipe 109 will not be blocked, and thus ensuring the normal operation of the device.
[0029] When using this device to clean channel silt, rotate the threaded rod 103. The threaded rod 103 drives the threaded cylinder 104 downward until one end of the conveying pipe 109 extends to the bottom of the channel. One end of the conveying pipe 109 is inserted into the silt. Start the pressure pump 108, which sucks the silt into the conveying pipe 109 and transports it to the storage tank 114 for collection through the connecting pipe 113. This is how channel silt is cleaned. The height of the inlet of the conveying pipe 109 can be adjusted in this way, allowing the conveying pipe 109 to clean silt at different depths, thereby improving the effect of channel silt cleaning.
[0030] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
