Description

Technical Field

[0001] This utility model relates to the technical field of underwater dredging equipment for water conservancy projects, and in particular to a high-efficiency grab bucket device for cleaning underwater silt in water conservancy projects. Background Technology

[0002] In water conservancy projects, siltation in rivers, lakes, reservoirs, and other water bodies has long been a problem. Silt not only reduces the water body's storage capacity and affects navigation safety, but it can also lead to water quality deterioration due to the release of pollutants.

[0003] A silt dredging grab bucket is a type of mechanical equipment specifically used in water conservancy projects (such as rivers, lakes, reservoirs, ports, and other water bodies) to remove underwater silt. It is a key tool in dredging operations. Its core function is to remove silt deposited on the bottom of the water body from the riverbed or pond bottom through mechanical grabbing, in order to restore the water body's storage capacity, navigation capacity, or improve water quality.

[0004] Existing devices require manual cleaning of residual silt inside the grab bucket after use. Manual cleaning involves close contact with the grab bucket's mechanical structure, which may lead to accidents such as pinching or crushing due to accidental equipment startup or loose parts, increasing the risk of personnel injury. Moreover, manual cleaning requires multiple processes such as stopping the machine, disassembling, shoveling, and rinsing, taking up to several hours per operation. Therefore, we propose a high-efficiency grab bucket device for cleaning underwater silt in water conservancy projects to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a high-efficiency grab bucket device for cleaning underwater silt in water conservancy projects, which can effectively solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1-5 As shown, a high-efficiency underwater silt cleaning grab device for water conservancy projects includes a connecting plate 1. A box 11 is fixedly connected to the top of the connecting plate 1. Two rotating rods 12 are rotatably connected to the inner walls of the left and right sides of the connecting plate 1. Grab buckets 13 are rotatably connected to the inner walls of the two rotating rods 12 on the left side and the two rotating rods 12 on the right side away from the connecting plate 1. A cleaning component 2 is provided below the connecting plate 1, and a sealing component 3 is provided below the connecting plate 1.

[0026] Specifically, in order to achieve the goal of automatically cleaning the inner wall of the grab bucket, refer to... Figure 2 and Figure 3 In this embodiment, the cleaning component 2 includes two reciprocating threaded rods 21. The front and back outer surfaces of the two reciprocating threaded rods 21 are rotatably connected to the inner wall of the grab bucket 13 on the same side. The two reciprocating threaded rods 21 are arranged symmetrically about the center of the connecting plate 1. Motors 211 are fixedly connected to the front of the two grab buckets 13. The output ends of the two motors 211 are fixedly connected to the front of the reciprocating threaded rods 21 on the same side.

[0027] Further reading Figure 2In this embodiment, two rotating frames 212 are fixedly connected to the outer surface of the reciprocating threaded rod 21, and the ends of the two rotating frames 212 that are far apart from each other are in contact with the inner wall of the grab bucket 13.

[0028] Further reading Figure 2 In this embodiment, a cleaning frame 22 is threadedly connected to the outer surface of the reciprocating threaded rod 21, a fixed rod 23 is fixedly connected to the inner wall of the grab bucket 13, a movable rod 231 is fixedly connected to the outer surface of the cleaning frame 22, the inner wall of the movable rod 231 is slidably connected to the outer surface of the fixed rod 23, and the outer surface of the cleaning frame 22 away from the fixed rod 23 is in contact with the inner wall of the grab bucket 13.

[0029] Further reading Figure 3 In this embodiment, a diversion box 24 is fixedly connected to the inner wall of the connecting plate 1, and a water inlet pipe 241 is fixedly connected to the top of the diversion box 24. The outer surface of the top front of the water inlet pipe 241 is fixedly connected to the inner wall of the box body 11, and a plurality of nozzles 242 are fixedly connected to the bottom of the diversion box 24.

[0030] During implementation, when the two grab buckets 13 need to be cleaned after the device has finished working, first connect the water pipe to the inlet pipe 241 so that water can enter the diversion box 24. The water entering the diversion box 24 will be sprayed onto the inner walls of the two grab buckets 13 through several nozzles 242. At the same time, turn on the two motors 211 to drive the corresponding reciprocating threaded rods 21 to rotate. When the reciprocating threaded rods 21 rotate, they will drive the two rotating frames 212 to rotate and clean the inner walls of the front and back of the corresponding grab buckets 13. While rotating, the cleaning frame 22 moves back and forth on the inner wall of the grab bucket 13 to clean the inner wall of the grab bucket 13. When the cleaning frame 22 moves, the moving rod 231 slides on the outer surface of the fixed rod 23, so that the cleaning frame 22 does not rotate with the reciprocating threaded rod 21. This not only eliminates the need for personnel to approach the mechanical parts of the grab bucket, thus completely eliminating the risk of pinching and squeezing accidents caused by accidental equipment operation and reducing the risk of personnel injury, but also allows for quick cleaning of the inner wall of the grab bucket 13, reducing the time spent on cleaning and improving cleaning efficiency.

[0031] Example 2: This example is based on Example 1, with the addition of a sealing component.

[0032] Specifically, in order to achieve the goal of sealing the gap between the two grabs, refer to... Figure 4 and Figure 5 In this embodiment, the sealing assembly 3 includes a sealing plate 31. The left end of the sealing plate 31 is fixedly connected to the right side of the grab bucket 13 located on the right side, and a fixing plate 32 is fixedly connected to the left side of the grab bucket 13 located on the left side.

[0033] Further reading Figure 4In this embodiment, a plurality of sliding rods 33 are slidably connected to the inner wall of the fixed plate 32, and a movable plate 34 is fixedly connected to the bottom of the plurality of sliding rods 33.

[0034] Further reading Figure 5 In this embodiment, a circular plate 331 is fixedly connected to the top of each of the sliding rods 33, a spring 332 is sleeved on the outer surface of each of the sliding rods 33, the top of each of the springs 332 is fixedly connected to the bottom of the fixed plate 32, and the bottom of each of the springs 332 is fixedly connected to the top of the moving plate 34.

[0035] During implementation, when the device is working, the hydraulic cylinder is activated to drive the corresponding grab bucket 13 to rotate. As the two grab buckets 13 rotate, they can grab underwater silt. During the rotation of the two grab buckets 13, they will drive the sealing plate 31 and the fixed plate 32 to rotate respectively. When the two grab buckets 13 rotate to a certain angle, the outer left surface of the rotating sealing plate 31 will contact the top right side of the rotating moving plate 34. As the two grab buckets 13 continue to rotate, the sealing plate 31 will push the moving plate 34 to move closer to the fixed plate 32. When the moving plate 34 moves, it will drive several sliding rods 33 to slide in the inner wall of the fixed plate 32. When the sliding rods 33 slide, they will squeeze the spring 332 to deform it. The deformed spring 332 will push the right surface of the rotating moving plate 34 to press tightly against the left surface of the rotating sealing plate 31 due to the elastic force. This can seal the gap at the bottom of the two rotating grab buckets 13, prevent silt from leaking out of the gap during grabbing, ensure the maximum amount of silt grabbed at one time, and improve the working efficiency of the device.

[0036] The working principle of this utility model is as follows: When the device is working, the hydraulic cylinder is activated to drive the corresponding grab bucket 13 to rotate. As the two grab buckets 13 rotate, they can grab the silt underwater. During the rotation of the two grab buckets 13, they will drive the sealing plate 31 and the fixed plate 32 to rotate respectively. When the two grab buckets 13 rotate to a certain angle, the outer left surface of the rotating sealing plate 31 will contact the top right side of the rotating moving plate 34. As the two grab buckets 13 continue to rotate, the sealing plate 31 will push the moving plate 34 to move closer to the fixed plate 32. When the moving plate 34 moves, it will drive several sliding rods 33 to slide in the inner wall of the fixed plate 32. When the sliding rods 33 slide, they will squeeze the spring 332 to deform it. The deformed spring 332 will push the right surface of the rotating moving plate 34 to stick tightly to the left surface of the rotating sealing plate 31 due to the elastic force. This can seal the gap at the bottom of the two rotating grab buckets 13, prevent the silt from leaking out of the gap during grabbing, ensure the maximum amount of silt grabbed at one time, and improve the working efficiency of the device.

[0037] When the device finishes its operation and the two grab buckets 13 need to be cleaned, first connect the water pipe to the inlet pipe 241 so that water can enter the distribution box 24. The water entering the distribution box 24 will be sprayed onto the inner walls of the two grab buckets 13 through several nozzles 242. At the same time, turn on the two motors 211 to drive the corresponding reciprocating threaded rods 21 to rotate. When the reciprocating threaded rods 21 rotate, they will drive the two rotating frames 212 to rotate and clean the inner walls of the front and back sides of the corresponding grab buckets 13. Simultaneously, the cleaning frame 22 will move back and forth on the inner wall of the grab bucket 13 to clean the inner wall of the grab bucket 13. When the cleaning frame 22 moves, the moving rod 231 will slide on the outer surface of the fixed rod 23, so that the cleaning frame 22 will not rotate with the reciprocating threaded rod 21. This not only eliminates the need for personnel to approach the mechanical parts of the grab bucket, thus completely eliminating the risk of pinching and squeezing accidents caused by accidental equipment operation and reducing the risk of personnel injury, but also allows for rapid cleaning of the inner wall of the grab bucket 13, reducing the time spent on cleaning and improving cleaning efficiency.
