Description

Technical Field

[0001] The utility model relates to a salvaging device, in particular to a salvaging device for floating objects on a water conservancy gate, and belongs to the technical field of river garbage cleaning. Background Art

[0002] Water is a precious resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control the flow of water, prevent floods and waterlogging, and regulate and distribute water to meet people's needs for water resources in life and production.

[0003] Gates are control facilities used to close and open water discharge channels and are an important part of hydraulic structures. They can be used to intercept water flow, control water level, regulate flow and floating objects, etc. As water flows toward the gates, floating objects on the river surface will gather toward the gate mouth with the water flow and float concentratedly at the gate mouth, causing dense garbage and seriously affecting the aesthetics of the river and water quality. When the gates are opened, the garbage will also flow downstream with the water flow, causing pollution to the downstream.

[0004] In daily life, in order to prevent floating objects from flowing into the downstream and polluting the downstream, which increases the difficulty and burden of cleaning up the downstream, floating objects need to be fished out manually in a timely manner before and after the gates are opened, resulting in a waste of manpower. Frequent fishing of floating objects poses a safety hazard to the operators and also increases costs. Utility Model Content

[0026] The utility model embodiment provides a device for salvaging floating objects of a hydraulic gate.

[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 , including a filter screen 26, a platform 18 is arranged on the top of the filter screen 26, a grab bucket 14 is arranged on the front side of the filter screen 26, threaded rods 9 are arranged on both sides of the grab bucket 14, three-slot plates 19 are arranged on the outside of the two threaded rods 9, the tops of the two threaded rods 9 pass through the platform 18 and are rotatably connected to the platform 18, a spring base 24 is fixedly connected to the front side of the platform 18, an impact rod 7 and a spring 8 are sleeved on the outside of the spring base 24, and the two ends of the spring 8 are respectively fitted with the spring base 24 and the impact rod 7.

[0028] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4 , the rear ends of both sides of the grab 14 are fixedly connected to the second support rod 13, and the bottoms of the two second support rods 13 are hinged with the first support rod 12, and the angle between the hinge leaves of the hinged first support rod 12 and the second support rod 13 is the flip angle of the grab 14, so that the grab 14 can only flip backwards and cannot flip forward. One side of the two first support rods 12 is fixedly connected to the internal threaded plate 11, and the two threaded rods 9 respectively penetrate the two internal threaded plates 11 and are threadedly connected to the internal threaded plates 11, and the bottom ends of the two threaded rods 9 are fixedly connected to the base 10 to prevent the internal threaded plate 11 from detaching from the threaded rod 9.

[0029] Please refer again Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The top of the platform 18 is fixedly connected with a rotating rod 22, and the outer side of the rotating rod 22 is rotatably connected with the second worm gear 5 and the half gear 23, the top of the half gear 23 is fixedly connected with the second worm gear 5, and one side of the half gear 23 is meshed with a toothed rod 6, and the top of the platform 18 is fixedly connected with the first limit plate 20 and the second limit plate 21, and one side of the toothed rod 6 is fixedly connected with the impact rod 7, and the outer side of the toothed rod 6 penetrates the first limit plate 20 and the second limit plate 21 and is slidably connected with the first limit plate 20 and the second limit plate 21. When working, the impact rod 7 fixed on the toothed rod 6 moves back and forth under the action of the spring 8 to knock the grab 14.

[0030] Please refer again Figure 1 , Figure 2 and Figure 3 The rear end of the grab bucket 14 is hingedly connected with a scraper 15, and the rear end of the scraper 15 is in contact with the filter screen 26. The rear end of the filter screen 26 is fixedly connected with a guide box 27. Two first limit rods 16 arranged opposite to each other are fixedly connected inside the grab bucket 14. The two first limit rods 16 correspond to the two sides of the scraper 15 respectively, and the scraper 15 is limited so that the scraper 15 cannot be flipped forward more than 90 degrees. The two sides of the grab bucket 14 are fixedly connected with second limit rods 25. When the grab bucket 14 rises, it drives the scraper 15 to scrape off the garbage on the filter screen 26 and clean the filter screen 26. At the same time, the guide box 27 allows the garbage to flow directly into the collection container. After the height of the garbage scraped off by the top of the scraper 15 exceeds the filter screen 26 and is not limited by the filter screen 26, it turns downward due to gravity and extends into the inside of the guide box 27.

[0031] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 5 The top of the platform 18 is fixedly connected to a motor 1 and a worm fixing plate 3 , the output end of the motor 1 is fixedly connected to a worm 2 , and the worm 2 penetrates the worm fixing plate 3 and is rotationally connected to the worm fixing plate 3 .

[0032] Please refer again Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7The tops of the two threaded rods 9 are fixedly connected with the first worm gear 4, and the two first worm gears 4 are meshed with the worm 2. The two internal threaded plates 11 are slidably connected with the two three-slot plates 19 respectively. The two three-slot plates 19 have limiting grooves 28 on opposite sides. The two second limiting rods 25 are slidably connected with the two limiting grooves 28 respectively. When the two second limiting rods 25 rise to the top of the two limiting grooves 28 with the grab bucket 14, the grab bucket 14 flips backward with the second limiting rod 25 as the axis. The other sides of the two three-slot plates 19 are fixedly connected with the water passage 30. The rear sides of the two three-slot plates 19 are fixedly connected with the mounting plates 29. The filter screen 26 is arranged inside the two mounting plates 29 and fixedly connected to the mounting plates 29 through bolts.

[0033] See also Figure 1 , Figure 2 and Figure 7 Two support frames 17 are fixedly connected to the bottom of the platform 18, the bottoms of the two support frames 17 are fixedly connected to the water passage 30, and one side of the two three-slot plates 19 is fixedly connected to the water passage 30 respectively.

[0034] When the utility model is in use, garbage follows the water flow into the grab bucket 14, and the output end of the motor 1 is fixedly connected to the worm 2. When it starts working, the two first worm wheels 4 meshing with the worm 2 start to rotate, driving the two threaded rods 9 respectively fixedly connected to the bottom ends of the two first worm wheels 4 to rotate. The two threaded rods 9 drive the two internal threaded plates 11 threadedly connected to the threaded rods 9 to rise, and the outer sides of the two internal threaded plates 11 are slidably connected to the inner sides of the two three-slot plates 19. The first support rods 12 are fixed on the opposite side of the two internal threaded plates 11, and the second support rods 13 are hinged on the upper ends of the two first support rods 12. A grab bucket 14 is fixedly connected between the two second support rods 13. Therefore, when the two internal threaded plates 11 rise, they drive the grab bucket 14 to rise along the direction of the three-slot plates 19. Figure 4Due to the positional relationship between the first support rod 12 and the second support rod 13, the second support rod 13 can only flip backwards, so the grab bucket 14 can only deflect backwards and will not deflect forwards under the gravity of the garbage. The rear end of the grab bucket 14 is hingedly connected with a scraper 15, and the scraper 15 is in contact with the filter screen 26. The scraper 15 is in contact with the filter screen 26 from the beginning. When the grab bucket 14 rises, it drives the scraper 15 and the filter screen 26 to scrape the garbage blocked by the filter screen 26 into the grab bucket 14. After the scraper 15 rises to the top of the filter screen 26 and there is no limit on the filter screen 26, it will flip down through the hinge. At this time, the top of the scraper 15 extends into the guide box 27 fixed on the other side of the top of the filter screen 26, so that the garbage can be diverted. When the garbage flows into the guide box 27, the rear ends of the two three-slot plates 19 are fixed with mounting plates 29, and the two mounting plates 29 fix the filter screen 26 to the rear ends of the three-slot plates 19 by bolts. Both three-slot plates 19 have a limit groove 28. The second limit rods 25 are fixedly connected to both sides of the rear end of the grab bucket 14, and the second limit rods 25 are slidably connected to the limit groove 28. When the grab bucket 14 rises, it drives the second limit rod 25 to move along the limit groove 28. The second limit rod 25 stops when the grab bucket 14 rises to the top of the limit groove 28. At this time, the internal threaded plate 11 continues to rise, which will drive the grab bucket 14 to tilt, so that the garbage is poured into the guide box 27 through the scraper 15 with gravity. A slope is provided inside the guide box 27, and garbage can be collected below the slope.

[0035] When the motor 1 is started, it drives the second worm gear 5 meshing with the worm 2 to rotate, and drives the half gear 23 fixedly connected to the second worm gear 5 to rotate, and the toothed rod 6 is fixedly connected to the impact rod 7. A spring 8 is provided at the rear end of the impact rod 7. When the half gear 23 rotates, the toothed rod 6 meshing with the half gear 23 is driven to move backward, and the impact rod 7 moves backward with the toothed rod 6 and compresses the spring 8. When the half gear 23 and the toothed rod 6 contact side turn to a smooth surface, the spring 8 makes the toothed rod 6 bounce back to the original position with the impact rod 7. Therefore, the front end of the impact rod 7 can repeatedly hit the tilting grab 14, so that the garbage adhering to the grab 14 is shaken off, thereby improving the garbage dropping effect of the grab 14 and improving the cleaning efficiency. A first limiting rod 16 corresponding to the scraper 15 is fixedly connected inside the grab 14. The first limiting rod 16 limits the scraper 15 so that the scraper 15 does not exceed 90 degrees when flipped forward, so that the scraper 15 still adheres to the filter screen 26 with gravity after the grab 14 returns after dumping the garbage.

[0036] Working principle: When the operation starts, the worm 2 rotates through the first worm wheel 4 to drive the threaded rod 9 to make the grab 14 rise along the slot on the three-slot plate 19. When it rises to a certain height, the limit grooves 28 on the three-slot plate 19 limit the second limit rods 25 fixed on both sides of the grab 14, so that the grab 14 flips backward. At the same time, the rotating rod 22 meshing with the worm 2 drives the half gear 23 to rotate, so that the gear rod 6 is repeatedly ejected by the spring 8 under the rotation of the half gear 23, shaking off the garbage on the grab 14, so that the garbage falls cleanly into the guide box 27 along the scraper 15 hinged at the rear end of the grab 14, which is convenient for centralized treatment.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
