Description

Technical Field

[0001] This utility model relates to the technical field of port and waterway dredging equipment, and in particular to a dredging device for port and waterway. Background Technology

[0002] With the rapid development of waterway transportation and the continuous increase in port throughput, the maintenance of port channels has become increasingly important. Siltation in channels not only affects the normal passage of ships and reduces navigation capacity, but also has adverse effects on the aquatic ecological environment. Therefore, regular dredging of port channels is an essential maintenance measure.

[0003] Currently, traditional port and waterway dredging operations mostly employ suction dredging equipment. This type of equipment uses a dredging pump to suck silt and sediment from the bottom of the water into the hull, where preliminary solid-liquid separation is then performed. However, in actual dredging processes, in addition to fine silt and sand, the bottom of the waterway is often accompanied by a large amount of domestic waste, construction debris, and other large pieces of debris.

[0004] When large pieces of debris are sucked into the dredging pipe along with the silt, their large size or irregular shape can easily cause blockages in the dredging pipe or subsequent transport pipelines. Once a blockage occurs, dredging operations must be immediately interrupted, requiring significant time and effort from staff to clear the blockage. This not only wastes manpower and resources but also severely impacts the continuity and overall efficiency of the dredging work. Furthermore, even if some large pieces of debris manage to pass through, they may cause wear and even damage to the pump and pipelines, increasing equipment maintenance costs and operational risks. Existing dredging equipment generally lacks an efficient and reliable mechanism to effectively handle large pieces of debris mixed in with the silt during dredging, ensuring the continuous unobstructed flow of the dredging pipelines. This has become a prominent problem restricting the improvement of port and waterway dredging efficiency.

[0005] Therefore, this utility model proposes a dredging device for ports and waterways to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a dredging device for port and waterway, which aims to improve the problems of existing dredging devices for port and waterway where the suction pipe is easily blocked by large pieces of garbage during sludge extraction, and the lack of an immediate volume reduction and temporary storage mechanism for the separated garbage.

[0008] The crushing assembly is fixedly connected to the inlet of the sludge suction pipe. The crushing assembly has a rotating blade structure for crushing large pieces of waste. The bracket is fixed above the processing box, and the cylinder is installed below the bracket. The output end of the cylinder is vertically connected to a pressure plate, which is located above the first chamber. Its structure enables the compression of the material in the first chamber.

[0009] The sludge suction pipe, connected to the crushing assembly, pre-treats large pieces of waste mixed in during the extraction process, preventing pipe blockage. The processing box achieves solid-liquid separation through an internal filter, and, combined with the support, cylinder, and pressure plate above, reduces and compresses the solid waste in the first chamber. The compressed waste is then transferred to the second chamber for temporary storage via an opening and closing plate, and finally, centralized cleaning is achieved through the cooperation of the box door and handle.

[0010] Preferably, the crushing assembly includes a placement shell, a motor mounted on the side wall of the placement shell, a first rotating shaft, a first gear, a second gear, a second rotating shaft, and crushing blades; the output shaft of the motor drives the first rotating shaft to rotate, the first rotating shaft is fixed with a first gear, the first gear meshes with the second gear, the second gear drives the second rotating shaft to rotate, and the second rotating shaft is fixed with crushing blades.

[0011] Preferably, the dredging device further includes a collection component, which includes an electric push rod hinged to the inner wall of the treatment tank. The output end of the electric push rod is fixed with a rotating plate, and the rotating plate is rotatably connected to a mounting block at the bottom of the opening and closing plate.

[0012] Preferably, the collection assembly further includes a fixing plate, a fixing rod, and a support plate; the fixing plate is fixed to the inner wall of the processing box, and the fixing rod is supported by the fixing plate; one end of the support plate is fixed to the bottom of the opening and closing plate, and the other end is slidably sleeved on the fixing rod.

[0013] Preferably, a sliding fit structure is provided between the periphery of the pressure plate and the inner wall of the first chamber, and the pressure plate can slide vertically along the inner wall of the first chamber.

[0015] Preferably, the door of the second chamber is connected to one side wall of the second chamber via a hinge mechanism, and the handle is connected to the locking component of the door via a linkage mechanism to control the opening and closing of the door.

[0016] Preferably, the opening and closing plate can rotate about one side of its connection with the first chamber to connect the first chamber and the second chamber.

[0017] This utility model has the following beneficial effects: 1. In this utility model, a crushing component is first fixedly connected at the inlet of the sludge suction pipe. The motor drives the crushing blades to rotate at high speed to pre-crush large pieces of garbage. This solves the problem of sludge removal interruption caused by large pieces of garbage clogging the suction pipe in existing sludge removal devices. This achieves the technical effect of greatly improving the continuity and efficiency of sludge removal operations and ensuring smooth pipeline operation.

[0018] 2. In this utility model, solid-liquid separation is achieved by setting up a filter screen inside the processing box, and the intercepted waste is compressed by using a cylinder to drive the pressure plate. Then, the compressed waste is transferred to the second chamber for temporary storage by the collection component driving the opening and closing plate. This solves the problem in the prior art that waste cannot be reduced in volume, processed and temporarily stored in time, which leads to inconvenience and low efficiency in subsequent waste disposal.

It achieves the technical effect of ensuring the smoothness and reliability of the transfer of compressed waste from the first chamber to the second chamber and improving the stability of equipment operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-6 The present invention provides an embodiment of a dredging device for port channels, which aims to solve the problems of existing dredging devices causing pipe blockage due to their inability to effectively handle large pieces of garbage, and the inability to compress and temporarily store the separated garbage, thereby affecting the continuity of dredging operations.

[0024] The dredging device for the port channel includes a hull 1, which serves as the mobile and load-bearing platform for the entire device. A dredging pump 2 is fixedly installed inside the hull 1. The suction port of the dredging pump 2 is connected to a dredging pipe 3, and the discharge port of the dredging pump 2 is connected to a processing tank 6 through a conveying pipe 5. The processing tank 6 is fixedly installed on the upper surface of the hull 1. A crushing component 4 is fixedly connected at the inlet of the dredging pipe 3. The crushing component 4 includes a placement shell 401, a motor 402 installed on the side wall of the placement shell 401, a first rotating shaft 403, a first gear 404, a second gear 405, a second rotating shaft 406, and crushing blades 407. The output shaft of the motor 402 drives the first rotating shaft 403 to rotate. The first gear 404 is fixed on the first rotating shaft 403. The first gear 404 meshes with the second gear 405. The second gear 405 drives the second rotating shaft 406 to rotate synchronously. The crushing blades 407 fixed on the second rotating shaft 406 rotate at high speed, thereby crushing large pieces of garbage mixed in during the dredging process before they enter the pipe. The interior of the processing box 6 is divided into an upper first chamber 11 and a lower second chamber 15. A filter screen 12 for solid-liquid separation is horizontally arranged in the first chamber 11, and an outlet 13 is opened on the side wall of the first chamber 11 and below the filter screen 12. Another core innovation of this device is its integrated waste compression and transfer structure. A bracket 8 is fixed directly above the processing box 6, and a cylinder 9 is installed below the bracket 8. The output end of the cylinder 9 is vertically connected to a pressure plate 10, which faces the interior of the first chamber 11 and is used to compress the waste intercepted by the filter screen 12. The bottom of the first chamber 11 is formed by an opening and closing plate 14. When the opening and closing plate 14 is closed, it seals the first chamber 11. When it is open, it connects the first chamber 11 with the lower second chamber 15 for transferring the compressed waste. A door is hinged to one side of the second chamber 15, and a handle 16 connected to the opening mechanism of the door is provided on the side wall of the hull 1 for final waste collection.

[0025] The collecting component 7 has an electric push rod 701, which is hinged to the inner wall of the processing box 6. A rotating plate 702 is fixedly connected to its output end. The rotating plate 702 is then rotatably connected to a mounting block 706 at the bottom of the opening / closing plate 14. When the electric push rod 701 is activated, the rotating plate 702 pushes the mounting block 706, causing the opening / closing plate 14 to deflect, thus opening the plate 14.

[0026] Meanwhile, to ensure the stability and guidance of the opening and closing plate 14 during the opening process, the collecting assembly 7 is also equipped with a fixing plate 705, a fixing rod 704, and a support plate 703. The fixing plate 705 is fixed to the inner wall of the processing box 6, and the fixing rod 704 is supported by and extends from the fixing plate 705; one end of the support plate 703 is fixed to the bottom of the opening and closing plate 14, and the other end is slidably sleeved on the fixing rod 704.

[0027] When the opening and closing plate 14 is deflected by the electric push rod 701, the support plate 703 slides along the side wall of the fixed rod 704, providing stable guidance and support for the opening and closing plate 14, preventing the opening and closing plate 14 from shaking or getting stuck during the opening process, and ensuring that the compressed waste can fall smoothly and steadily from the first chamber 11 into the lower second chamber 15. This cooperative working mechanism ensures that the opening and closing plate 14 can perform a controlled and smooth opening operation.

[0028] To ensure that the pressure plate 10 moves stably in the vertical direction when compressing waste and to prevent tilting or jamming, a sliding fit structure is provided between the periphery of the pressure plate 10 and the inner wall of the first chamber 11, such as... Figure 2 and Figure 4 As shown, the edge of the pressure plate 10 may be provided with a guide groove, which cooperates with the corresponding guide rib or track on the inner wall of the first chamber 11. Alternatively, the shape of the pressure plate 10 may be tightly fitted with the shape of the inner wall of the first chamber 11 with an appropriate gap, so that the pressure plate 10 can slide vertically up and down along the inner wall of the first chamber 11. This sliding fit structure ensures that the compression stroke of the pressure plate 10 driven by the cylinder 9 is stable and precise, improving the uniformity and efficiency of waste compression.

[0029] To further optimize the connection stability and integrity between the crushing component 4 and the sludge suction pipe 3, the placement shell 401 of the crushing component 4 extends along the axial direction of the sludge suction pipe 3 and is coaxially and fixedly connected to the inlet end of the sludge suction pipe 3. This coaxial fixed connection method ensures that the crushing blades 407 of the crushing component 4 can efficiently and without eccentricity process the material entering the sludge suction pipe 3, minimizing fluid resistance and wear, while enhancing the structural strength and sealing of the connection, effectively preventing loosening of the connection or leakage of foreign matter.

[0030] To facilitate the centralized disposal of compressed waste, a door is hinged to the side wall of the second chamber 15. The door is connected to one side wall of the second chamber 15 via a hinge mechanism. A handle 16 is provided on the side wall of the hull 1. The handle 16 is connected to the locking component of the door via a linkage mechanism to control the opening and closing of the door. When the handle 16 is pulled, the linkage mechanism releases the door from its locked state, causing it to swing or slide outward along the hinge mechanism, thus allowing the waste in the second chamber 15 to be dumped and disposed of. This design makes the centralized waste disposal process simple, fast, and low in labor costs.

[0031] To facilitate material transfer between the first chamber 11 and the second chamber 15, the opening and closing plate 14 can rotate around its connection point with the first chamber 11 on one side, thus connecting the first chamber 11 and the second chamber 15. This rotation axis of the opening and closing plate 14 is typically achieved through a hinged structure. When the opening and closing plate 14 rotates and opens around this axis under the drive of the collecting assembly 7, the space that was originally closed at the bottom of the first chamber 11 is opened, allowing the compressed waste to fall freely into the second chamber 15 directly below it. This single-sided rotation opening method is simple in structure, easy to control, and ensures that waste can be transferred quickly and effectively from the upper chamber to the lower chamber.

[0032] Working principle: When dredging is carried out, the hull 1 sails to the designated water area, the dredging pump 2 starts, and the dredging pipe 3 extracts the silt and garbage from the bottom of the water. At the same time, the crushing component 4, which is fixedly connected to the inlet of the dredging pipe 3, works synchronously. Its motor 402 drives the first rotating shaft 403 and the first gear 404 to rotate. Through the meshing transmission with the second gear 405, the second rotating shaft 406 and the crushing blade 407 fixed on the second rotating shaft 406 are driven to rotate at high speed, so as to pre-crush the large pieces of garbage entering the dredging pipe 3 and prevent large debris from clogging the subsequent conveying pipe 5.

[0033] The crushed waste and sludge mixture is transported through the conveying pipe 5 to the first chamber 11 of the processing tank 6. The sludge and fine particles pass through the filter screen 12 and are discharged through the outlet 13 located below the side wall of the first chamber 11, while larger solid waste is intercepted by the filter screen 12. After the waste accumulates to a certain amount, the cylinder 9 installed on the support 8 above the processing tank 6 is activated, driving the pressure plate 10 downward to squeeze, dehydrate, and reduce the volume of the waste in the first chamber 11. After compression, the electric push rod 701 of the collection component 7 is activated, pushing the rotating plate 702, which in turn drives the opening and closing plate 14 to open downward around its rotation axis. Under the guidance of the support plate 703 along the fixed rod 704, the opening and closing plate 14 opens smoothly, allowing the compressed waste to fall into the second chamber 15 below for storage under gravity.

[0034] When the second chamber 15 is full of garbage, the operator pulls the handle 16 on the side wall of the hull 1 to operate the opening mechanism and locking component connected to the door, so that the door of the second chamber 15 can be opened, and the garbage can be dumped and cleaned in a centralized manner, completing a complete work cycle.
