Description

Technical Field

[0001] This utility model relates to the field of ship dredging, and in particular to a dredging vessel. Background Technology

[0002] A sand dredging vessel is a type of vessel that uses the suction power of a sand pump to draw up river sand or sludge from underwater and then discharge it to a designated location through an upper discharge pipe. Sand dredging vessels are suitable for dredging and sand extraction projects in reservoirs, major rivers, artificial lakes, and coastal ports.

[0003] However, the sand dredging vessels currently in use are designed as a whole and are very expensive. The hull of the sand dredging vessels is large and difficult to use for dredging in narrow spaces. In addition, the sand dredged by the sand dredging vessels needs to be temporarily stored on the ship. After the capacity limit of the ship is reached, it needs to go back and forth to the riverbank to discharge the sand, resulting in low sand dredging efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing sand dredging vessels, such as high cost, inconvenience of dredging in confined spaces, and the need to travel back and forth to the riverbank during the dredging process, and to provide a sand dredging vessel.

[0005] This utility model provides a sand dredging vessel, including

[0006] The vessel includes a hull, deck, dredging frame, power unit, dredging device, and a dredging pipeline for discharging sand to the riverbank. The deck is detachably connected to the hull, and the dredging frame is detachably connected to the hull. The power unit is connected to the top of the deck. The dredging device is connected to the dredging frame, the dredging pipeline is connected to the dredging device, and the power unit is connected to the dredging device. The power unit is used to drive the dredging device.

[0007] This utility model discloses a sand dredging vessel. Because the deck and hull are detachably connected, and the sand dredging frame is also detachably connected, the vessel can be used as a regular ship after the deck and dredging frame are removed. The sand dredging frame allows adjustment of the position of the sand dredging device, moving it away from the hull to improve dredging efficiency. The power unit is installed on top of the deck for easy maintenance by operators. One end of the discharge pipeline extends to the shore, allowing direct discharge of sand to the shore, preventing sand from being stored on the hull and thus avoiding the need for the sand dredging vessel to travel back and forth during dredging. This utility model also discloses a sand dredging vessel that can be modified from a small vessel, enabling it to be used for dredging in confined spaces and reducing the cost of dredging equipment.

[0008] Preferably, the hull has a receiving space and an opening, the opening being located on the top side of the hull and communicating with the receiving space, the deck covering the opening, and the deck being adapted to and connected with the opening.

[0009] After the deck and dredging frame are dismantled, the hull can be used to carry gravel and silt, enabling the hull to be used for rock dumping and dredging; by adapting the shape of the deck to the shape of the opening, the deck is installed and embedded into the opening, so that the deck is firmly fixed to the hull.

[0010] Preferably, the deck includes a first plate and a second plate, the first plate and the second plate are hinged together, and the power unit is connected to the first plate.

[0011] After the second plate rotates to a certain extent, some openings are exposed, allowing workers to retrieve stones encountered during the dredging process and store them in the storage space, thus enabling the dredging vessel to perform both dredging and stone dumping functions.

[0012] Preferably, the accommodating space is provided with a support column, which abuts against the deck.

[0013] The support columns increase the support area of ​​the deck, change the stress distribution on the deck, reduce deck deformation, prevent deck collapse, and make the sand dredging vessel safer to use.

The base is connected to the bow of the hull, the adjusting rod is hinged to the base, the sand dredging device is connected to the end of the adjusting rod, and the sand discharge pipeline is connected to the adjusting rod.

[0015] The operator controls the position of the sand dredging device by adjusting the lever, enabling the device to move vertically and descend to the designated depth for sand dredging operations. The middle part of the adjusting lever is hinged to the base, allowing the operator to stand on the hull and control the depth of the sand dredging device by adjusting the end of the lever.

[0016] Preferably, the base includes a first seat and a second seat, the first seat is located on top of the second seat, the first seat and the second seat are rotatably connected, the first seat is connected to the adjusting rod, and the second seat is connected to the hull.

[0017] The first and second seats are rotatably connected, allowing the adjusting rod to rotate in the horizontal direction, thereby adjusting the horizontal position of the sand-dredging device and improving the sand-dredging efficiency.

[0018] Preferably, the end of the adjusting rod away from the sand-dredging device is provided with a counterweight, and / or the hull is provided with a hydraulic device connected to the adjusting rod.

[0019] By configuring a block to balance the weight of the sand-dredging device, operators can more easily adjust the position of the sand-dredging device; the hydraulic device makes it easier to adjust the adjusting rod.

[0021] A first power supply mechanism and a second power supply mechanism are installed on the deck. A first sand pump and a second sand pump are installed at the end of the sand pumping frame. The first sand pump is driven by the first power supply mechanism, and the second sand pump is driven by the second power supply mechanism, forming two independent sand pumping devices. One sand pumping device is used as a backup. If the sand pump in use fails during the sand pumping process, it can be switched to the other sand pump to continue the operation, reducing the impact of sand pumping equipment failure on sand pumping efficiency.

The sand dredging device 5 is connected to the sand dredging frame 3. The sand discharge pipeline 6 is connected to the sand dredging device 5. The power unit 4 is connected to the sand dredging device 5 and is used to drive the sand dredging device 5.

[0046] Because the deck 2 and the hull 1 are detachably connected, and the sand dredging frame 3 and the hull 1 are detachably connected, the hull 1 can be used as a regular vessel after the deck 2 and the sand dredging frame 3 are removed. The sand dredging frame 3 can adjust the position of the sand dredging device 5, moving it away from the hull 1 to improve dredging efficiency. The power unit 4 is installed on top of the deck 2 for easy maintenance by operators. One end of the sand discharge pipeline 6 extends to the shore, allowing the sand discharge pipeline 6 to discharge sand directly to the shore, avoiding the storage of silt on the hull 1 and thus avoiding the sand dredging vessel having to travel back and forth during the dredging process. This utility model provides a sand dredging vessel that can be modified into a small vessel, enabling it to be used for sand dredging in confined spaces and reducing the cost of sand dredging equipment.

[0047] Specifically, the sand drainage pipeline 6 is a flexible hose.

The second base 322 is fixedly connected to the hull 1, so that the sand dredging device 5 can move horizontally.

[0053] In some embodiments, a counterweight 33 is provided at the end of the adjusting rod 31 away from the sand dredging device 5. The weight of the counterweight 33 is equal to the weight of the sand dredging device 5, allowing the operator to move the adjusting rod 31 more easily. In other embodiments, the counterweight 33 is detachably connected to the adjusting rod 31. By replacing the counterweight 33 with a different weight, the balance effect on the sand dredging device 5 can be changed. In some embodiments, the counterweight 33 is slidably mounted on the adjusting rod 31. By controlling the distance between the counterweight 33 and the hinge point, the weight balance effect of the counterweight 33 on the sand dredging device 5 can be adjusted.
