Description

Technical Field

[0001] This utility model relates to the field of dredging technology, and in particular to a cutter head device for a cutter suction dredging vessel and a cutter suction dredging vessel. Background Technology

[0002] A dredger is a vessel specifically designed for underwater dredging operations, primarily used to remove sediment from waterways, ports, and lakes to maintain channel depth and improve the aquatic environment. A cutter suction dredger is a type of dredger that works by using a cutter head to loosen sediment at the bottom of the water, then using a suction pipe to pump the dredged material onto the dredger. However, in existing cutter suction dredgers, the operators cannot directly monitor the underwater dredging process. They can only indirectly determine if the cutter head has encountered rocks by observing the pressure parameters fed back from the cutter head. Direct contact between the cutter head and rocks results in significant impact, easily damaging the cutter head. Furthermore, when rocks are sucked into the suction pipe, it can cause blockages, affecting the smoothness of the dredging operation. Utility Model Content

[0003] The main purpose of this utility model is to propose a cutter head device for a cutter suction dredger and a cutter suction dredger, aiming to solve the technical problems in the prior art where cutter head is easily damaged and suction pipe is easily blocked when encountering rocks, affecting the smoothness of dredging operations.

[0004] To achieve the above objectives, this utility model proposes a cutter head device for a cutter suction dredger, comprising a cutter head assembly, a crushing assembly, and a monitoring assembly. The cutter head assembly includes a cutter head, a first driving member, and multiple spaced-apart cutters, each cutter head being rotatably connected to the cutter head. The first driving member drives each cutter head to rotate relative to the cutter head. The crushing assembly includes a crusher, a mounting frame, and a second driving member. The mounting frame is connected to the cutter head and spaced apart from each cutter head. The crusher is mounted on the end of the mounting frame away from the cutter head. The second driving member drives the crusher to crush rocks. The monitoring assembly is mounted on the mounting frame and includes a camera, a lighting lamp, and a communication module. The camera and the lighting lamp are both oriented towards the crusher. The communication module is electrically connected to the camera and communicatively connected to a backend system.

[0005] In one embodiment, the cutter head is strip-shaped, and a plurality of the augers are spaced apart along the extension direction of the cutter head, so that the cutter head and the plurality of augers form a rake-like structure.

[0006] In one embodiment, each of the reamers includes a cutting edge side and a back edge side, and the multiple cutting edges of the plurality of reamers face the same direction.

[0007] In one embodiment, each of the augers has a plurality of teeth spaced apart on its blade side, and each tooth is serrated.

[0008] In one embodiment, each of the blades is detachably connected to the reamer.

[0009] In one embodiment, the reamer is a high-strength alloy reamer, and the surface of the cutting teeth is coated with a wear-resistant coating.

[0010] In one embodiment, the cutter disc is provided with suction holes, which are staggered with each of the augers. The crusher includes multiple crushing blades, which are arranged around the suction holes.

[0011] In one embodiment, the cutter head is provided with a protective cover, and a plurality of the cutters are located inside the protective cover. The protective cover is provided with a plurality of through holes and a plurality of clearance holes spaced apart. A plurality of the crushing cutters are correspondingly inserted through the clearance holes and extend to the outside of the protective cover. Each of the through holes is connected to the sludge suction hole.

[0012] In one embodiment, the lighting lamp is an angle-adjustable LED lamp.

[0013] This utility model also proposes a cutter suction dredger that uses the aforementioned cutter head device.

[0014] This invention proposes a cutter head device for a cutter suction dredger and a cutter suction dredger. During the process of the cutter head assembly loosening and excavating sediment at the bottom of the water, a camera captures the underwater dredging operation. An illumination lamp provides underwater lighting for the camera, ensuring clear images. A communication module transmits the camera footage to a backend system for real-time monitoring of the underwater dredging operation. This allows operators to promptly detect and handle any abnormalities during the dredging process, thereby improving safety. When the cutter head assembly encounters a large rock, the operator uses a second drive unit to activate a pulverizer to break the rock into smaller particles. These smaller particles are then sucked onto the cutter suction dredger via the suction pipe, preventing direct impact from the rock to the cutter head, effectively protecting the cutter head, and preventing rock blockage of the suction pipe, thus improving the smoothness of the underwater dredging operation.

[0024] During underwater dredging operations, the operators on board existing cutter suction dredgers cannot directly know the underwater dredging situation. They can only indirectly judge whether the cutter has encountered rocks by the pressure parameters fed back by the cutter head. Direct contact between the cutter head and rocks causes the cutter head to be subjected to a large impact, which can easily damage the cutter head. Moreover, when rocks are sucked into the suction pipe, they can easily cause blockage of the suction pipe, affecting the smoothness of the dredging operation.

[0025] This utility model proposes a cutter head device for a cutter suction dredger, including a cutter head assembly 100, a crushing assembly, and a monitoring assembly. The cutter head assembly 100 includes a cutter head 10, a first drive member, and multiple spaced-apart cutters 20. Each cutter 20 is rotatably connected to the cutter head 10. The first drive member drives each cutter 20 to rotate relative to the cutter head 10. The crushing assembly includes a crusher, a mounting frame, and a second drive member. The mounting frame is connected to the cutter head 10 and spaced apart from each cutter 20. The crusher is mounted on the end of the mounting frame away from the cutter head 10. The second drive member drives the crusher to crush rocks. The monitoring assembly is mounted on the mounting frame and includes a camera, a lighting lamp, and a communication module. The camera and the lighting lamp are both oriented towards the crusher. The communication module is electrically connected to the camera and communicatively connected to a backend system.

[0026] Please see Figure 1 The cutter head device proposed in this utility model is used in a cutter suction dredger 200. The cutter suction dredger 200 is equipped with a suction pipe 210, and the cutter head device is located at the end of the suction pipe 210. When the cutter suction dredger 200 is performing dredging operations, by extending the suction pipe 210 underwater, the cutter head device is brought deep into the bottom of the water. The first drive unit drives multiple cutter heads 20 to rotate relative to the cutterhead 10. The multiple cutter heads 20 loosen and excavate the sediment at the bottom of the water, so that the suction pipe 210 can pump the loosened sediment onto the cutter suction dredger 200. The camera transmits the underwater images captured by the camera to the backend via the communication module, so as to facilitate real-time monitoring of the underwater dredging operation. When the cutter head device encounters a large rock, the second drive unit drives a crusher to crush the rock into fine particles, so that the suction pipe 210 can pump the fine particles onto the cutter suction dredger 200. It should be noted that the driving methods of the first driving component and the cutter 20, as well as the driving methods of the second driving component and the crusher in this utility model, all adopt existing technologies.

[0027] The cutter head device for a cutter suction dredger proposed in this utility model, during the process of loosening and excavating sediment at the bottom of the water, captures underwater dredging operations via a camera. A lighting system illuminates the underwater footage, ensuring clear images. A communication module transmits the camera's images to a backend system for real-time monitoring of the underwater dredging operation. This allows operators to promptly detect and address any abnormalities during the dredging process, thereby improving safety. When the cutter head assembly 100 encounters a large rock, the operator uses a second drive unit to activate a crusher to break the rock into smaller particles. These particles are then sucked onto the cutter head 200 via the suction pipe 210, preventing direct impact from the rock and effectively protecting the cutter head 20. This also prevents rocks from clogging the suction pipe 210, thus improving the smoothness of the underwater dredging operation.

[0028] In one embodiment, the cutter head 10 is strip-shaped, and a plurality of augers 20 are spaced apart along the extending direction of the cutter head 10, so that the cutter head 10 and the plurality of augers 20 form a rake-like structure.

[0029] Please see Figure 2 Multiple cutter heads 20 are spaced apart along the extension direction of the cutter head 10, enabling multiple cutter heads 20 to simultaneously extend into the bottom of the water and uniformly loosen and excavate the sediment within the extension direction of the cutter head 10, effectively expanding the coverage area of ​​the cutter head assembly 100, improving the loosening efficiency of the sediment, and thus improving the dredging efficiency of the cutter head device.

[0030] In one embodiment, each reamer 20 includes a cutting edge side 22 and a back edge side 23, and the multiple cutting edge sides 22 of the multiple reamers 20 face the same direction.

[0031] Please see Figure 2 The cutting edges 22 of multiple cutter heads 20 all face the same direction. During the movement of the cutter suction dredger 200, the cutting edges 22 of multiple cutter heads 20 all face the front side of the moving direction of the cutter suction dredger 200. This allows the multiple cutter heads 20 to loosen and excavate the sediment located in front of the cutter suction dredger 200, while avoiding wear on sediment in other directions. This makes the movement of the cutter head assembly 100 smoother, reduces vibration and wear caused by uneven force on the cutter heads 20, and thus extends the service life of the cutter heads 20.

[0032] In one embodiment, each reamer 20 has a plurality of teeth 21 spaced apart on its blade side 22, and each tooth 21 is serrated.

[0033] Please see Figure 2The blade side 22 is provided with multiple blade teeth 21 at intervals, and each blade tooth 21 is serrated, so that the blade can form multiple cutting points when cutting the sediment. The multiple cutting points are distributed at intervals along the blade side 22, which can act on the sediment within the blade range at the same time, effectively expanding the dredging range of the cutter assembly 100 and significantly improving the dredging efficiency of the cutter device.

[0034] In one embodiment, each blade 21 is detachably connected to the reamer 20.

[0035] Understandably, the detachable connection of the cutter teeth 21 allows operators to quickly replace the cutter teeth 21 when they are worn or damaged, without having to replace the entire cutter head 20. This reduces the time and cost required for the maintenance of the cutter head assembly 100, thereby improving the efficiency of the cutter head dredging operation.

[0036] In one embodiment, the reamer 20 is a high-strength alloy reamer 20, and the surface of the blade teeth 21 is coated with a wear-resistant coating.

[0037] Understandably, the high-strength alloy material of the reamer 20 possesses excellent impact resistance and mechanical strength, enabling it to maintain its integrity and stability when facing hard deposits or rocks. The wear-resistant coating on the surface of the cutting teeth 21 further enhances their wear resistance. During cutting, the cutting teeth 21 frequently come into contact with deposits and generate friction; the wear-resistant coating effectively reduces wear on the surface of the cutting teeth 21, extending their service life.

[0038] In one embodiment, the cutter head 10 is provided with suction holes, which are staggered with each auger 20. The crusher includes multiple crushing heads, which are arranged around the suction holes.

[0039] It should be noted that the staggered distribution of the suction holes and the cutter head 20 ensures that the operation of the cutter head 20 and the suction process do not interfere with each other. This also ensures that during the cutting process by the cutter head 20, the loosened sediment can flow smoothly into the suction holes, preventing sediment from accumulating between the cutter head 10 and the cutter head 20. Multiple crushing blades of the pulverizer are arranged around the suction holes. When large stones or hard sediments are sucked near the suction holes, the crushing blades can quickly crush them into fine particles, ensuring that these fine particles can smoothly pass through the suction holes into the suction pipe 210, preventing blockage of the suction pipe 210.

[0040] In one embodiment, the cutter head 10 is covered with a protective cover, and multiple cutters 20 are located inside the protective cover. Multiple through holes and multiple clearance holes are spaced apart on the protective cover. Multiple crushing cutters are correspondingly inserted through the clearance holes and extend to the outside of the protective cover. Each through hole is connected to the suction hole.

[0041] Furthermore, a protective cover is installed over the multiple cutter heads 20, which can effectively prevent large sediments from directly impacting the cutter heads 20, thereby protecting the cutter heads 20 from wear and extending their service life. Multiple crushing cutter heads extend outside the protective cover through corresponding clearance holes to facilitate the crushing of rocks. The crushed fine particles then pass through through holes into the suction holes and are thus pumped onto the cutter suction dredger 200.

[0042] In one embodiment, the lighting is an angle-adjustable LED light.

[0043] Understandably, angle-adjustable LED lights can flexibly adjust the lighting direction according to the actual dredging operation needs, ensuring that the camera obtains the best lighting effect when shooting underwater. In complex underwater environments, such as when sediment is suspended, light is insufficient, or visibility is low, operators can remotely control the angle of the LED lights to ensure that the light accurately illuminates the dredging area, thereby improving the clarity and visibility of the captured images.

[0044] This utility model also proposes a cutter suction dredger 200, which uses the cutter head device described above. The specific structure of the cutter head device is as described in the above embodiments. Since this cutter suction dredger 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0045] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
