Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a grab bucket device for dredging river channels in water conservancy projects. Background Technology

[0002] Water conservancy projects are the artificial construction of facilities such as dams, dikes, canals, and pumping stations to manage natural water resources. Regulation, development, utilization and protection Water resources are a comprehensive engineering system designed to serve objectives such as flood control, water supply, irrigation, power generation, navigation, and ecological protection. Its essence lies in coordinating the relationship between humans and water to achieve efficient utilization and sustainable development of water resources.

[0003] In water conservancy construction, single-rope grab buckets are often used when cleaning river channels. However, when grabbing river silt, due to the strong stickiness of the silt, some silt will adhere to the inner wall of the grab bucket after it is lowered. When the cleaning work is finished and the grab bucket is idle, the silt adhering to the inner wall of the grab bucket solidifies, making it difficult for workers to clean. To address this, we have proposed a grab bucket device for river dredging in water conservancy projects. Utility Model Content

[0004] The purpose of this utility model is to provide a grab bucket device for dredging river channels in water conservancy projects. After the grab bucket body has grabbed the silt from the river channel, the grab bucket body can be rinsed in advance by connecting the rinsing structure with an external water pump. During the rinsing process, as the winding mechanism applies force to the rotating sleeve, it can drive the scraper to scrape along the inner wall of the grab bucket body, thereby cleaning the grab bucket body. This not only facilitates the next use, but also reduces the trouble of manual cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grab bucket device for dredging river channels in water conservancy projects, comprising a grab bucket body, an upper crossbeam, and a movable plate. A fixed plate is hinged to the inner side of the grab bucket body on both sides. A sliding rod for sliding the upper crossbeam is fixedly connected to the top of the fixed plate. A limit plate is provided at the top of the sliding rod. Two fixed blocks are provided on both sides of the top of the fixed plate. A rotating sleeve is hinged between the two fixed blocks. A movable rod is slidably connected inside the rotating sleeve. A limit block is fixed to one side of the movable rod. A scraper is fixedly connected to the other end of the movable rod. A spring is fixedly connected to the other side of the limit block, and the other end of the spring is fixed to the inner wall of the rotating sleeve. The diameter of the limit block is larger than that of the movable rod. A tension spring for rebounding after the rotating sleeve is rotated is provided on the other side of the rotating sleeve, and the other end of the tension spring is fixed to one side of the fixed plate. A winding mechanism is provided at the top of the limit plate, and a flushing mechanism is provided inside the scraper.

[0006] Preferably, the rinsing mechanism includes a fixed water pipe, a first water pipe, a second water pipe, and water pipe nozzles. The fixed water pipe is fixed to the inside of the scraper. There are several water pipe nozzles connected to the fixed water pipe. The water pipe nozzles are angled inward. One end of the first water pipe is connected to the fixed water pipe, and one end of the first water pipe on both sides is connected to one end of the second water pipe.

[0007] Preferably, the winding mechanism includes a dual-axis motor, a winding reel, and a pull rope. The dual-axis motor is fixed to the top of the limiting plate, and both ends of the dual-axis motor are connected to the inner sides of the two winding reels. The pull rope is wound around the surface of the winding reel, and the other end of the pull rope is fixed to one end of the rotating sleeve.

[0008] Preferably, folded plates are fixedly connected to both sides of the top of the fixed plate, guide wheels are provided in front of the folded plates, and guide rods are provided on both sides of the upper crossbeam.

[0009] Preferably, square grooves are provided on both the upper and lower sides of the inner cavity of the rotating sleeve, and the upper and lower sides of the limiting block are slidably connected to the inner wall of the square grooves.

[0010] Preferably, two limiting rods are provided on the top of the grab bucket bodies on both sides, and one side of the limiting rod is in contact with the outer side of the scraper.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] After the grab bucket body has finished grabbing the silt in the river channel, the grab bucket body can be rinsed in advance by connecting the rinsing structure with the external water pump. During the rinsing process, as the winding mechanism applies force to the rotating sleeve, it can drive the scraper to scrape along the inner wall of the grab bucket body, thereby cleaning the grab bucket body. This not only facilitates the next use, but also reduces the trouble of manual cleaning. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-5 As shown, a grab bucket device for river dredging in water conservancy projects includes a grab bucket body 1, an upper crossbeam 2, and a movable plate 5. Fixed plates 4 are hinged to the inner sides of the grab bucket bodies 1 on both sides. A sliding rod 3 for sliding the upper crossbeam 2 is fixedly connected to the top of the fixed plate 4. A limit plate 6 is provided on the top of the sliding rod 3. Two fixed blocks 12 are provided on both sides of the top of the fixed plate 4. A rotating sleeve 10 is hinged between the two fixed blocks 12. A movable rod 11 is slidably connected inside the rotating sleeve 10. A limit plate 6 is fixed on one side of the movable rod 11. The other end of the movable rod 11 is fixedly connected to the positioning block 16, and the other side of the limiting block 16 is fixedly connected to the spring 17, and the other end of the spring 17 is fixed to the inner wall of the rotating sleeve 10. The diameter of the limiting block 16 is larger than that of the movable rod 11. The other side of the rotating sleeve 10 is provided with a tension spring 18 for rebounding after the rotating sleeve 10 is rotated, and the other end of the tension spring 18 is fixed to one side of the fixing plate 4. The top of the limiting plate 6 is provided with a winding mechanism 7, and the inner side of the scraper 14 is provided with a rinsing mechanism 9.

[0021] The rinsing mechanism 9 includes a fixed water pipe 91, a first water pipe 92, a second water pipe 94, and water pipe nozzles 93. The fixed water pipe 91 is fixed to the inside of the scraper 14. There are several water pipe nozzles 93 connected to the fixed water pipe 91. The angle of the water pipe nozzles 93 is inclined inward. One end of the first water pipe 92 is connected to the fixed water pipe 91. The two first water pipes 92 are connected to one end of the second water pipe 94. With this configuration, when the scraper 14 cleans the inner wall of the grab body 1, water can be delivered through the water pump connected to the outside of the second water pipe 94. The water is diverted when passing through the two first water pipes 92, so as to rinse the inner wall that needs to be cleaned, thereby improving the cleaning efficiency of the scraper 14.

[0022] The winding mechanism 7 includes a dual-axis motor 71, a winding reel 72, and a pull rope 73. The dual-axis motor 71 is fixed to the top of the limiting plate 6. Both ends of the dual-axis motor 71 are connected to the inner sides of the two winding reels 72. The pull rope 73 is wound around the surface of the winding reel 72, and the other end of the pull rope 73 is fixed to one end of the rotating sleeve 10. After the dual-axis motor 71 is turned on, the pull rope 73 is wound around the surface of the winding reel 72. The pull rope 73 will pull one end of the rotating sleeve 10, and then the scraper 14 moves on the inner wall of the grab body 1, thereby cleaning the inner wall of the grab body 1.

[0023] Both sides of the top of the fixed plate 4 are fixedly connected with folded plates 13. A guide wheel 15 is provided in front of the folded plate 13. Guide rods 19 are provided on both sides of the upper crossbeam 2. This arrangement can adjust the pulling direction of the pull rope 73, thereby adjusting the rotation direction of the rotating sleeve 10 so that it can rotate to the bottom of the inner cavity of the grab body 1.

[0024] Square grooves 8 are provided on both the upper and lower sides of the inner cavity of the rotating sleeve 10. The upper and lower sides of the limiting block 16 are slidably connected to the inner wall of the square grooves 8. In this way, the stability of the limiting block 16 moving on the inner wall of the rotating sleeve 10 can be increased by setting the square grooves 8 and the limiting block 16.

[0025] Two limiting rods 20 are provided on the top of both grab bucket bodies 1, and one side of the limiting rod 20 is in contact with the outer side of the scraper 14. Thus, by setting the limiting rod 20, the movable rod 11 is pushed by the elastic force of the spring 17, so that the limiting rod 20 can be in close contact with the surface of the scraper 14, so that the scraper 14 can be in close contact with the inner wall of the grab bucket body 1, thereby better cleaning work.

[0026] Working principle: When cleaning the river channel, the grab bucket body 1 grabs the silt. After grabbing the silt, it is moved to the desired location. Then, the grab bucket body 1 is opened, and the silt is dropped. Since the grab bucket device is a relatively mature existing technology, its specific operation is not described in this solution. After multiple uses, a large amount of silt remains on the inner wall of the grab bucket body 1. At this time, the second water pipe 94 is connected to an external water pump to supply water to the pipe, and then the water is sprayed out from the water pipe nozzle 93. The sludge on the inner wall of the grab bucket is flushed away. Then, the dual-shaft motor 71 is turned on. As the output end of the dual-shaft motor 71 drives the winding reel 72 to rotate, the pull rope 73 wound on the surface of the winding reel 72 is wound and stretched. As the pull rope 73 is pulled, it will pull one end of the rotating sleeve 10 through the guide wheel 15, causing it to rotate. At this time, through the elastic force of the spring 17 itself, the scraper 14 can always be driven to stick tightly to the inner wall of the grab bucket body 1 to scrape, thus cleaning the sludge attached to the inner wall of the grab bucket body 1.
