Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a convenient grab bucket device for underwater slag removal from imported slopes. Background Technology

[0002] During long-term operation, underwater debris, such as gravel and sediment mixtures, is easily formed on the underwater slope at the inlet of the reservoir spillway due to water erosion, siltation, or rockfall. If these debris are not cleaned up in time, they will not only cross the flow section and affect the normal function of the project, but also change the water flow trajectory due to the accumulation of debris, exacerbate slope erosion, and threaten the structural safety of the slope. According to the search, Chinese patent CN217923806U provides a dredging grab bucket suitable for underwater slope excavation. The device reduces the squeezing and scraping disturbance of the slope soil during the excavation process by designing a concave bucket body, multiple sets of support arms and rope wheel structure, thereby reducing the risk of slope collapse and having certain advantages in underwater slope soil protection. However, during use, it was found that the device still did not solve the key adaptation problem of slag removal from the inlet slope. The inlet slope is often diverse due to the influence of engineering design and natural erosion. The angle of the existing grab bucket is mostly fixed, which makes it difficult to adjust flexibly according to the actual slope. If the angle of the grab bucket does not match the slope, it will easily lead to the grab bucket not fitting tightly with the slope, resulting in problems such as slag leakage and low grabbing efficiency. In some cases, the grab bucket may even damage the structure of the treated slope due to hard scraping between the grab bucket and the slope, which is not conducive to the underwater slag removal of the inlet slope. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a convenient grab bucket device for underwater slag removal from inlet slopes. It enables flexible adjustment of the bucket's tilt angle, reduces the leakage of slag from the gap between the bucket and the inlet slope body during grabbing, increases the single grabbing volume, further improves underwater slag removal efficiency, reduces hard scraping between the bucket and the inlet slope body, and protects the treated slope structure.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a convenient grab bucket device for underwater slag removal from an inlet slope, including an inlet slope body, a grab bucket mechanism on one side of the inlet slope body, the grab bucket mechanism including two buckets, a filter assembly inserted into the bucket, and slope adjustment components installed at both ends of the bucket respectively; The slope adjustment assembly includes a rotating shaft, one end of which is rotatably connected to the bucket body. A protective shell is rotatably connected to the rotating shaft and fixedly connected to the outer wall of the bucket body. A worm gear is rotatably connected inside the protective shell, and a worm wheel is meshed on the worm gear. The worm wheel is sleeved on the outer peripheral wall of the rotating shaft. A first servo motor is installed at one end of the protective shell, and the output shaft of the first servo motor is coaxially connected to the worm gear. An actuating tube is fixedly provided at the end of the rotating shaft away from the bucket body. A movable rod is slidably connected inside the actuating tube, and a rotating wheel is rotatably connected to the movable rod.

[0005] Preferably, the outer wall of the first servo motor is equipped with a metal heat dissipation shell, a push block is fixed on the movable rod, a protective cover is fixed on the actuating tube, a lead screw is provided inside the protective cover, and the push block is threadedly connected to the lead screw through a threaded hole.

[0006] Through the above technical solution, the heat generated by the first servo motor during operation is conducted to the outside through the metal heat dissipation shell on the outer wall.

[0007] Preferably, a second servo motor is installed inside the protective cover, the output shaft of the second servo motor is coaxially connected to the lead screw, and a plurality of heat dissipation holes are opened at one end of the metal heat dissipation shell, and the heat dissipation holes are filled with waterproof and breathable valves.

[0008] Through the above technical solution, the heat dissipation holes facilitate the heat dissipation of the second servo motor, while the waterproof and breathable valves filled inside the heat dissipation holes ensure air circulation and heat dissipation while preventing underwater water and sediment from entering the motor, thus reducing the risk of short circuits or damage to the second servo motor.

[0009] Preferably, the filter assembly includes a filter block, a slot is provided at one end of the bucket body, the filter block is inserted into the slot, a filter groove is provided on the bucket body, and a plurality of reinforcing blocks are fixed on the bucket body, the filter block and the reinforcing blocks are slidably connected.

[0010] Preferably, one end of the filter block is fitted with a plurality of hexagonal socket head cap screws, and the threaded ends of the plurality of hexagonal socket head cap screws are respectively threadedly connected to the bucket body.

[0011] Using the above technical solution, the filter block is inserted into the slot at one end of the bucket body. During the process, the filter block slides along the reinforcing block on the bucket body. After insertion, the filter block is fixed to the bucket body by multiple hexagonal bolts.

[0012] Preferably, one end of the filter block is provided with a U-shaped rod, and two grooves are formed at one end of the filter block, with the two ends of the U-shaped rod located inside the two grooves respectively.

[0013] Preferably, one end of the bucket body is provided with a U-shaped groove, and the U-shaped rod is engaged with the U-shaped groove.

[0014] Preferably, two round rods are rotatably connected to both ends of the U-shaped rod, and a torsion spring is sleeved on the outer peripheral wall of the round rod. One end of the torsion spring is fixedly connected to the outer peripheral wall of the U-shaped rod, and the other end of the torsion spring is fixedly connected to the bucket body.

[0015] The above technical solution involves using a U-shaped groove to pull a U-shaped rod to rotate along a round rod. At this point, the U-shaped rod separates from the U-shaped groove, making it easy to pull the U-shaped rod through the round rod to remove the filter block for cleaning or replacement, thus ensuring long-term stable drainage performance.

[0016] The beneficial effects of this utility model are as follows: When it is necessary to adapt to different slopes of the inlet slope body, the output shaft of the first servo motor drives the worm gear inside the protective shell to rotate. Since the worm gear meshes with the worm wheel sleeved on the outer peripheral wall of the rotating shaft, the rotation of the worm gear will be converted into the rotation of the worm wheel, which in turn drives the rotating shaft connected to the bucket body to rotate synchronously. When the rotating shaft rotates, it will drive the actuating tube to adjust the angle. At the same time, the movable rod slidably connected inside the actuating tube extends or retracts with the angle change, so that the rotating wheel on the movable rod fits against the slope surface of the inlet slope body, realizing the flexible adjustment of the bucket body tilt angle. This makes it easy to adapt to the diverse slopes of the inlet slope formed by engineering design and natural erosion. There is no need to replace the grab bucket mechanism or frequently adjust the tooling. This reduces the situation where the slag is missed from the gap between the bucket body and the inlet slope body during grabbing, increases the single grabbing volume, further improves the underwater slag discharge efficiency, reduces the hard scraping between the bucket body and the inlet slope body, and protects the treated slope structure.

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figures 1-7 As shown, this embodiment provides a convenient grab bucket device for underwater slag removal from an inlet slope, including an inlet slope body 100. A grab bucket mechanism 101 is provided on one side of the inlet slope body 100. The grab bucket mechanism 101 includes two buckets 102. A filter assembly 200 is inserted into the bucket 102. A slope adjustment assembly 300 is installed at both ends of the bucket 102. The slope adjustment component 300 includes a rotating shaft 301, one end of which is rotatably connected to the bucket body 102. A protective shell 302 is rotatably connected to the rotating shaft 301 and is fixedly connected to the outer wall of the bucket body 102. A worm gear 303 is rotatably connected inside the protective shell 302, and a worm wheel 304 is meshed on the worm gear 303. The worm wheel 304 is sleeved on the outer peripheral wall of the rotating shaft 301. A first servo motor 305 is installed at one end of the protective shell 302. The output shaft of the first servo motor 305 is coaxially connected to the worm gear 303. An actuating tube 306 is fixedly provided at the end of the rotating shaft 301 away from the bucket body 102. A movable rod 307 is slidably connected inside the actuating tube 306, and a rotating wheel 308 is rotatably connected to the movable rod 307.

[0021] The first servo motor 305 has a metal heat sink shell 309 installed on its outer wall. A push block 310 is fixed on the movable rod 307, and a protective cover 314 is fixed on the actuating tube 306. A lead screw 311 is provided inside the protective cover 314. The push block 310 is threadedly connected to the lead screw 311 through a threaded hole. The heat generated by the first servo motor 305 when it is working is conducted to the outside through the metal heat sink shell 309 on its outer wall.

[0022] The protective cover 314 houses a second servo motor 312. The output shaft of the second servo motor 312 is coaxially connected to the lead screw 311. One end of the metal heat sink 309 has multiple heat dissipation holes 313, and the heat dissipation holes 313 are filled with waterproof and breathable valves. The heat dissipation holes 313 facilitate the dissipation of heat from the second servo motor 312, while the waterproof and breathable valves filled inside the heat dissipation holes 313 ensure air circulation and heat dissipation while preventing underwater water and sediment from entering the motor, thus reducing the risk of short circuits or damage to the second servo motor 312.

[0023] The filter assembly 200 includes a filter block 201. A slot 202 is provided at one end of the bucket body 102, and the filter block 201 is inserted into the slot 202. A filter groove 203 is provided on the bucket body 102. A plurality of reinforcing blocks 204 are fixed on the bucket body 102. The filter block 201 is slidably connected to the reinforcing blocks 204. A plurality of hexagonal socket head cap screws 205 are inserted into one end of the filter block 201, and the threaded ends of the plurality of hexagonal socket head cap screws 205 are respectively threadedly connected to the bucket body 102. The filter block 201 is aligned with the slot 202 at one end of the bucket body 102 and inserted. During the process, the filter block 201 slides along the reinforcing blocks 204 on the bucket body 102. After insertion, the filter block 201 is fixed to the bucket body 102 by the plurality of hexagonal socket head cap screws 205.

[0024] One end of the filter block 201 is provided with a U-shaped rod 206, and two grooves 207 are opened at one end of the filter block 201. The two ends of the U-shaped rod 206 are respectively located inside the two grooves 207. One end of the bucket body 102 is provided with a U-shaped groove 208. The U-shaped rod 206 is engaged with the U-shaped groove 208. Two round rods 209 are rotatably connected to the two ends of the U-shaped rod 206. A torsion spring 210 is sleeved on the outer peripheral wall of the round rod 209. One end of the torsion spring 210 is fixedly connected to the outer peripheral wall of the U-shaped rod 206, and the other end of the torsion spring 210 is fixedly connected to the bucket body 102. By pulling the U-shaped rod 206 along the round rod 209 through the U-shaped groove 208, the U-shaped rod 206 is separated from the U-shaped groove 208. This makes it easy to pull the U-shaped rod 206 through the round rod 209 to remove the filter block 201 for cleaning or replacement, ensuring long-term stable drainage effect.

[0025] Working principle: When it is necessary to adapt to different slopes of the imported slope body 100, the output shaft of the first servo motor 305 drives the worm 303 inside the protective shell 302 to rotate. Since the worm 303 meshes with the worm wheel 304 sleeved on the outer peripheral wall of the rotating shaft 301, the rotation of the worm 303 will be converted into the rotation of the worm wheel 304, which in turn drives the rotating shaft 301, which is rotated and connected to the bucket body 102, to rotate synchronously. When the rotating shaft 301 rotates, it drives the actuating tube 306 to adjust the angle. At the same time, the movable rod 307, which is slidably connected inside the actuating tube 306, extends or retracts with the change of angle, so that the rotating wheel 308 on the movable rod 307 fits against the slope surface of the inlet slope body 100. This realizes the flexible adjustment of the tilt angle of the bucket body 102, which is convenient to adapt to the various slopes formed by engineering design and natural scouring of the inlet slope. There is no need to replace the grab bucket mechanism 101 or frequently adjust the tooling. This reduces the situation where the slag is missed from the gap between the bucket body 102 and the inlet slope body 100 during grabbing, increases the single grabbing volume, further improves the underwater slag discharge efficiency, reduces the hard scraping between the bucket body 102 and the inlet slope body 100, and protects the treated slope structure. After the angle of the two buckets 102 of the grab bucket mechanism 101 is adjusted, they grab the underwater slag. The filter component 200 inserted on the bucket 102 facilitates the filtration and discharge of water entrained in the slag during the grabbing process, reducing the overall load on the grab bucket. When it is necessary to further adapt to the slope undulation or fine-tune the fit between the rotating wheel 308 and the slope, the output shaft of the second servo motor 312 drives the lead screw 311 inside the protective cover 314 to rotate. The rotation of the lead screw 311 is converted into the linear motion of the push block 310, which in turn pushes or pulls the movable rod 307 to slide inside the actuating tube 306, thereby controlling the extension length of the movable rod 307 and ensuring that the rotating wheel 308 fits the slope surface of the inlet slope body 100, thus improving the grabbing effect and grabbing efficiency of the slag. The heat generated by the first servo motor 305 during operation is conducted to the outside through the metal heat sink shell 309 on the outer wall; at the same time, multiple heat dissipation holes 313 at one end of the metal heat sink shell 309 facilitate the heat dissipation of the second servo motor 312, and the waterproof and breathable valves filled inside the heat dissipation holes 313 ensure air circulation and heat dissipation while preventing underwater water and mud from entering the motor, reducing the risk of short circuit or damage to the second servo motor 312. When installing the filter assembly 200, the filter block 201 is aligned with the slot 202 at one end of the bucket body 102 and inserted. During the process, the filter block 201 slides along the reinforcing block 204 on the bucket body 102. After insertion, the filter block 201 is fixed to the bucket body 102 by multiple hexagonal bolts 205. At the same time, the U-shaped rod 206 is rotated to make it snap into the U-shaped groove 208 of the bucket body 102. The torsion springs 210 on the outer periphery of the round rods 209 at both ends of the U-shaped rod 206 will generate elastic tension, fixing the U-shaped rod 206 in the U-shaped groove 208. When removing the filter block 201 for replacement, first separate the hex bolt 205 from the bucket body 102, and then pull the U-shaped rod 206 along the round rod 209 through the U-shaped groove 208. At this time, the U-shaped rod 206 is separated from the U-shaped groove 208, making it easy to pull the U-shaped rod 206 through the round rod 209 to remove the filter block 201 for cleaning or replacement, ensuring long-term stable drainage effect; When grabbing the slag, the filter block 201 cooperates with the filter groove 203 on the bucket body 102 to facilitate the filtration and discharge of water from the slag, thus facilitating the slag discharge of the grab bucket mechanism 101.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
