Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly workboat technology, and in particular to an environmentally friendly multi-functional workboat. Background Technology

[0002] To purify water quality, improve the environment, and dredge waterways, dredging vessels are commonly used. There are many types of dredging vessels, with cutter suction dredgers, consisting of a cutter head and a mud pump, being widely used. These dredgers operate by rotating and swinging a cutter head mounted at the front of the cutter head, and by using a mud pump to suction pollutants above the design elevation to a designated area. Cutter suction dredgers manufactured in conventional shipyards, whether domestically produced or imported, generally exhibit the following similar problems during daily use:

[0003] Conventional cutter suction dredgers lack environmental protection devices and can only perform simple cleaning of riverbed silt during construction. They cannot completely remove domestic waste from the riverbed and can only achieve a preliminary remediation effect.

[0004] When conventional cutter suction dredgers are used for construction in urban inland rivers, the cutter head and mud pump are easily entangled or damaged by the large amount of domestic waste, bricks and tiles on the riverbed, which affects the construction progress.

[0005] Conventional cutter suction dredgers typically use rotary scraper cutters to cut river mud, which can easily cause large-scale turbidity and pollution of the water in the construction area. The mud pumps extract mud with high water content and low concentration.

[0006] Conventional cutter suction dredgers have low slurry concentration and low efficiency.

[0007] In response to the aforementioned problems, the applicant has conducted research and improvements, providing an environmentally friendly, multi-functional work vessel that not only meets the requirements of environmentally friendly dredging but also achieves integrated obstacle removal and silt removal. This significantly improves overall construction efficiency, ensures reliable quality, and avoids secondary pollution.

[0008] Therefore, we propose an environmentally friendly, multi-functional work vessel. Utility Model Content

[0009] To address the shortcomings of existing production technologies, the applicant provides an environmentally friendly, multi-functional work vessel. This vessel utilizes a high-speed rotating environmentally friendly cutter head to convey river and lake bottom sediment via a spiral conveyor to a high-concentration conveyor frame. The internal spiral and mud pump suction then transport the high-concentration mud to the mud inlet. The mud pump effectively removes the sediment, ensuring efficient operation and improving overall work efficiency.

[0010] The technical solutions adopted in this utility model are as follows:

[0011] An environmentally friendly, multi-functional work vessel, comprising:

[0012] The hull serves as the support platform for the entire working vessel;

[0013] The sludge treatment and conveying equipment, installed on the hull, is used to cut and transport river and lake bottom sludge. It includes an environmentally friendly high-concentration hydraulic reamer, a high-concentration conveying cutter holder, and a lifting and lowering hydraulic cylinder for the sludge. The environmentally friendly high-concentration hydraulic reamer is connected to the high-concentration conveying cutter holder, and the lifting and lowering hydraulic cylinder for the sludge is used to control the raising and lowering of the high-concentration conveying cutter holder.

[0014] The mud pump, connected to the high-concentration conveying cutter holder, is used to pressurize and convey the cut mud to achieve dredging operations;

[0015] The environmentally friendly, highly concentrated hydraulic cutter cuts the mud at the bottom of rivers and lakes, and then transports the cut mud to a highly concentrated conveying cutter holder. The mud is then pumped to remove silt, achieving integrated construction of environmentally friendly dredging, obstacle removal and silt removal.

[0016] As a further improvement of the above technical solution:

[0017] The high-concentration conveying cutter holder is rotatably connected to one side of the hull and is equipped with a spiral conveying device inside, which is used to efficiently transport the cut mud to the mud pump.

[0018] The high-concentration conveying cutter holder is equipped with a cutting port for docking with the environmentally friendly high-concentration hydraulic reamer, and docks with the environmentally friendly high-concentration hydraulic reamer through a flexible joint to ensure smooth flow of mud.

[0019] The lifting hydraulic cylinder of the gantry is fixed to one end of the hull by a bracket, and its movable end is hinged to the high concentration conveying cutter holder to control the lifting and lowering of the high concentration conveying cutter holder to adapt to river and lake bottom mud of different depths.

[0020] It also includes a chain drive mechanism, which is connected to the screw conveyor and is responsible for transmitting the power of the motor to the screw conveyor, driving it to rotate inside the high-concentration conveying knife holder.

[0021] It also includes positioning piles and positioning pile lifting and lowering hydraulic cylinders. The positioning piles are movably inserted into the hull in the vertical direction. The insertion depth of the positioning piles is controlled by the positioning pile lifting and lowering hydraulic cylinders to fix the hull and ensure stability and safety during construction.

[0022] It also includes a trolley and a trolley hydraulic cylinder. The trolley is connected to the hull through the trolley hydraulic cylinder to push the hull to move, realize cyclic swing dredging, and improve construction efficiency.

[0023] It also includes a ship swing winch, which is used to control the swing of the ship. The rotation of the winch drives the steel wire rope to be released and tightened, so as to realize the swing of the ship for dredging.

[0024] The environmentally friendly, highly concentrated hydraulic reamer includes a motor and a reamer. The motor controls the reamer to rotate and cut, which can reduce noise and vibration while cutting river and lake bottom mud, thus reducing pollution to the surrounding water bodies.

[0025] The mud pump is sealed to the other end of the conveying cutter holder via a rubber hose, ensuring smooth mud transport and efficient processing.

[0026] The beneficial effects of this utility model are as follows:

[0027] This utility model has a compact and reasonable structure and is easy to operate. The environmentally friendly cutter head rotates at high speed to transport the river and lake bottom mud to the high concentration conveying cutter holder through the spiral conveying device. The high concentration mud is transported to the mud inlet by the internal spiral and the suction of the mud pump. The mud pump sucks up the mud for effective dredging. This device ensures the high efficiency of the mud pump's inlet mud concentration, improving the work efficiency. Compared with traditional hulls, the mud concentration can be increased by 10-15%.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0032] like Figure 1 As shown in the illustration, this embodiment discloses an environmentally friendly multi-functional work vessel, aiming to solve the problems of traditional work vessels, such as lack of environmental protection devices, susceptibility to riverbed garbage and rubble, turbidity and pollution of the water in the construction area, and low slurry concentration and efficiency. This work vessel achieves integrated environmentally friendly dredging, obstacle removal and silt removal, improving the overall construction efficiency and effectively avoiding secondary pollution.

[0033] Its structure includes an environmentally friendly high-concentration hydraulic reamer 1, a high-concentration conveying cutter holder 2, a lifting and lowering hydraulic cylinder 3, a chain drive mechanism 4, a ship swing winch 5, an operating room 6, a trolley hydraulic cylinder 7, a positioning pile lifting and lowering hydraulic cylinder 8, a positioning pile 9, a hydraulic station 10, a hull 11, a mud pump 12, a rubber hose 13, a screw conveyor device 14, and a flexible joint 15. This environmentally friendly multi-functional work vessel adopts an advanced design concept, perfectly combining environmental protection, high efficiency, and durability. The overall structure is compact and the layout is reasonable.

[0034] Specifically, such as Figure 1 As shown, the hull 11 in this embodiment serves as the support platform for the entire work vessel and is made of high-strength materials, capable of withstanding harsh aquatic environments.

[0035] Simultaneously, the positioning pile 9 is vertically inserted into the hull 11, and is connected to the hull 11 via a positioning pile lifting and lowering hydraulic cylinder 8. The insertion depth of the positioning pile 9 can be controlled by the positioning pile lifting and lowering hydraulic cylinder 8. The positioning pile 9 is used to fix the hull 11 and is made of high-strength material, capable of withstanding harsh aquatic environments. During operation, by lowering the positioning pile, the stability and safety of the hull 11 can be ensured, avoiding construction errors and safety hazards.

[0036] It also includes a trolley, which is connected to the hull 11 via a trolley hydraulic cylinder 7. The trolley propels the hull 11 to move and is made of high-strength materials, capable of withstanding the weight of the hull 11 and the impact forces during movement. During operation, after the mud in the swinging area is cleared, the trolley can move backward a certain distance and then push the hull 11 forward again to achieve cyclic swinging dredging, improving construction efficiency and ensuring the continuity and stability of the dredging operation.

[0037] The sludge treatment and conveying equipment in this embodiment includes an environmentally friendly high-concentration hydraulic reamer 1, a high-concentration conveying cutter holder 2, and a lifting hydraulic cylinder 3 connected to each other. It can move up and down in the water to cut the sludge at the bottom of the pool and also transport the sludge at the bottom of the pool.

[0038] Specifically, the high-concentration conveying cutter holder 2 is rotatably connected to one side of the hull 11. The high-concentration conveying cutter holder 2 is equipped with a spiral conveying device 14 to realize the transfer of sludge. It adopts a special design that can efficiently transport the cut sludge to the subsequent treatment equipment while cutting the river and lake bottom mud.

[0039] The high-concentration conveying cutter holder 2 is equipped with a cutting port that connects with the environmentally friendly high-concentration hydraulic reamer 1. The high-concentration conveying cutter holder 2 connects with the environmentally friendly high-concentration hydraulic reamer 1 through a flexible connector 15, ensuring smooth flow of mud.

[0040] The hydraulic cylinder 3, which controls the lifting and lowering of the lifting frame, is fixed to one end of the hull 11 via a bracket. Its movable end is hinged to the high-concentration conveying cutter holder 2, and it controls the lifting and lowering of the high-concentration conveying cutter holder 2 to ensure that the cutter holder can accurately cut into the river and lake bottom sediment. The hydraulic cylinder is designed to balance stability and durability, and can operate stably for a long time in harsh working environments. By precisely controlling the extension and retraction of the hydraulic cylinder, the height of the cutter holder can be easily adjusted to adapt to river and lake bottom sediments of different depths.

[0041] The environmentally friendly, highly concentrated hydraulic reamer consists of a motor and a reamer. The motor controls the reamer's rotation for cutting, reducing noise and vibration while cutting river and lake bottom mud, thus minimizing pollution to the surrounding water. The reamer's design also considers the impact of riverbed debris and rubble, easily handling these obstacles and preventing entanglement or damage to the reamer head and mud pump.

[0042] The chain drive mechanism 4 and the screw conveyor 14 together constitute the mud conveying system of this utility model. The chain drive mechanism is responsible for transmitting the power of the motor to the screw conveyor, driving it to rotate inside the high-concentration conveying cutter holder. The screw conveyor is responsible for conveying the cut mud from the cutter holder to the mud pump 12. This system adopts an efficient and durable design, ensuring smooth mud conveying and efficient processing.

[0043] The mud pump 12, which is sealed to the other end of the conveying cutter holder 2 via a rubber hose 13, is responsible for pressurizing and conveying the mud supplied to the mud pump to achieve dredging operations. The mud pump is designed considering the mud concentration and flow rate, and adopts advanced pumping technology and materials to ensure efficient and stable operation. By optimizing the parameter settings of the mud pump, the efficiency and quality of dredging operations can be further improved.

[0044] The ship swing winch 5 is used to control the swing of the hull 11. It adopts advanced winch technology and materials, and can precisely control the swing angle and speed of the hull 11. By rotating the winch, the steel wire rope can be tightened and loosened, thereby realizing the swing of the hull 11 for dredging, improving construction efficiency, and ensuring the uniformity and thoroughness of the dredging operation.

[0045] It also includes an operator's cab 6 and a hydraulic station 10, which enable control and power transmission.

[0046] The high-concentration conveying cutter holder 2 is lowered by the lifting hydraulic cylinder 3. The environmentally friendly high-concentration hydraulic cutter 1 cuts the river and lake bottom mud and conveys the cut mud to the high-concentration conveying cutter holder 2. The motor drives the chain transmission mechanism to drive the screw conveyor to rotate inside the high-concentration conveying cutter holder 2, conveying the mud to the mud pump 12 for dredging. The hull 11 is fixed by lowering the positioning pile 9. The ship swing winches 5 on both sides of the hull 11 are started. The ship swing winches 5 rotate, and the steel wire rope is loosened and tightened to make the hull 11 swing for dredging. After the mud in the swing area is cleared, the trolley moves backward to push the hull 11 forward a certain distance, and then the swing dredging cycle is repeated.
