Description

Technical Field

[0001] The present invention relates to the technical field of trash rack cleaning, and in particular to a self-cleaning trash rack based on smart water conservancy. Background Art

[0002] Smart water conservancy is the innovative application of relevant advanced concepts and high-tech in the water conservancy industry generated in the construction of a smart society represented by smart cities. It is a comprehensive application of cloud computing, big data, the Internet of Things, sensors and other technologies, and is widely used in pumping stations, hydropower stations, etc. Trash racks are generally installed at the water inlets of pumping stations, hydropower stations and ship lock water delivery corridors to block water plants, driftwood and other dirt carried in the water flow, so that the dirt is not easy to flow into the waterway, so as to protect the unit, gates, valves and pipelines from damage and ensure the safe operation of equipment and structures such as the unit. When the upstream water contains too much debris, the dirt is attached to the surface of the trash rack, making the dirt passing capacity insufficient, resulting in frequent excessive pressure difference of the trash rack and high frequency of cleaning.

[0003] There are two main ways to clean trash racks: manual cleaning and mechanical cleaning. Manual cleaning mainly relies on manual use of tools for cleaning. Although this method is flexible to operate, it is time-consuming, labor-intensive and inefficient. Since trash racks are usually located in aquatic environments, manual cleaning is not only labor-intensive, but also poses safety hazards. Mechanical cleaning uses mechanical equipment for automated or semi-automated cleaning. Although mechanical cleaning improves cleaning efficiency to a certain extent, existing mechanical cleaning equipment is often complex in structure, cumbersome to operate, and the cleaning effect is not ideal, making it difficult to meet the actual use needs of staff. Therefore, the present invention proposes a self-cleaning trash rack based on smart water conservancy. Summary of the invention

Due to the action of water flow, some small sludge impurities will pass through the trash rack 2. Therefore, the first driving mechanism 7 is provided to intercept the small sludge, and then the second driving mechanism 8 and the second cleaning mechanism 9 are provided to cooperate so that the small impurities piled on the front side of the trash plate 708 are adsorbed by the adsorption holes 903, and then the impurities adsorbed on the second cleaning mechanism 9 are cleaned out by the action of the second driving mechanism 8, thereby achieving comprehensive cleaning and optimization of the trash rack 2, which is helpful to promote water conservancy, environmental protection and sustainable development.

[0022] In another embodiment provided by the present invention, Figure 4-6 As shown, the first cleaning mechanism 4 includes a first mounting frame 401, and the first mounting frame 401 is internally rotatably connected to a first screw rod 402, and a first motor 403 that drives the first screw rod 402 to rotate is provided on one side of the first mounting frame 401, and the first screw rod 402 is externally threadedly connected to a first movable member 404, and a sliding hole 405 is provided on the first movable member 404, and mounting grooves 406 are provided on both sides of the sliding hole 405 of the first movable member 404, and buffer rods 407 are linearly distributed inside the mounting grooves 406 on both sides along the groove body direction, and pulleys 408 are connected to the opposite sides of the plurality of buffer rods 407 on both sides.

[0023] Furthermore, the first cleaning mechanism 4 also includes a pneumatic push rod 409, which is fixedly installed on the top of the first movable part 404, and the output end of the pneumatic push rod 409 is fixedly connected to a movable head 410, and the bottom of the movable head 410 is fixedly connected to a first connecting rod 411, and the bottom of the first connecting rod 411 is fixedly connected to a movable frame 412, and a top column 413 is provided between the upper and lower plates on the back side of the movable frame 412, and the front side plate of the movable frame 412 is provided with a cleaning brush 414 that cooperates with the trash rack 2, and a number of cleaning brushes 414 are arranged along the direction of the plate body, and a propulsion frame 415 is provided at the bottom of the side of the front side plate of the movable frame 412 that is opposite to the cleaning brush 414.

[0024] Furthermore, the movable head 410 is slidably engaged with the upper surface of the first movable member 404 through the first connecting rod 411 , the outer surface of the first connecting rod 411 is in contact with the outer surface of the pulley 408 , and a plurality of cleaning brushes 414 are arranged corresponding to the grid plates on the trash rack 2 .

[0025] Furthermore, a monitor 10 is fixedly mounted on the top of the propulsion frame 415 .

[0026] In this solution, when the monitor 10 detects that there is too much dirt on the front side of the trash rack 2, the pneumatic push rod 409 first drives the movable head 410 to slide on the upper surface of the first movable member 404, and the movable head 410 drives the first connecting rod 411 to follow the movement under the action of the pulley 408, and then adjusts the movable frame 412 so that the cleaning brush 414 on the front side plate of the movable frame 412 fits the grid plate on the trash rack 2, and then drives the first screw rod 402 to rotate through the first motor 403. Since the first movable member 404 is threadedly connected to the first screw rod 402, the first movable member 404 is connected to the first screw rod 402. The movable member 404 will move along the axial direction of the first screw rod 402, and the first movable member 404 drives the movable frame 412 to move along the grid direction of the trash rack 2, thereby pushing the dirt floating on the front side of the trash rack 2 to the discharge mechanism 5 on one side, and at the same time, the cleaning brush 414 cleans the sludge attached to the grid of the trash rack 2, and the pushing frame 415 set at the bottom of the front side plate of the movable frame 412 pushes the sludge accumulated at the bottom of the trash rack 2 to the discharge mechanism 5 on one side, and then cooperates with the discharge mechanism 5 to discharge the dirt. The monitor 10 is a mature existing technology and will not be described in detail here.

[0027] In another embodiment provided by the present invention, Figure 7-9As shown, the discharge mechanism 5 includes a fixed frame 501, which is arranged on one side of the interior of the water channel 1, and the front side of the fixed frame 501 is arranged to be open. A second screw rod 502 is rotatably mounted inside the fixed frame 501, and a guide rod 503 is arranged on the side of the second screw rod 502. A second movable member 504 is connected to the outer surface of the guide rod 503 by a thread on the outside of the second screw rod 502. The second movable member 504 is slidably connected to the outer surface of the guide rod 503. A connecting member 505 is connected to the side of the second movable member 504 facing the open door of the fixed frame 501. A limiting frame 506 is arranged on one side of the interior of the fixed frame 501, and a Hose 507, and the side of the limit frame 506 close to the connecting piece 505 is set to open the door, the hose 507 passes through the connecting piece 505 The connecting hole 508 is opened, and the other end of the connecting hole 508 is connected to the water channel 1. The top of the fixed frame 501 is fixedly installed with a second motor 509 for rotating the second screw rod 502. The end of the hose 507 away from the connecting piece 505 is fixedly connected to the output end of the sewage pump 510 provided at the top of the water channel 1. The output end of the sewage pump 510 is connected to a sewage pipe 511. A sewage trough 512 is opened on one side of the top of the water channel 1, and the sewage trough 512 is correspondingly arranged below the sewage pipe 511.

[0028] In this solution, after the first cleaning mechanism 4 pushes the dirt, the second motor 509 drives the second screw rod 502 to rotate, so that the second movable member 504 moves along the path of the second screw rod 502 and the guide rod 503 to the place where the dirt floats, ensuring that the connecting hole 508 is always aligned with the position of the dirt that needs to be discharged, and then the sewage pump 510 is started to suck the floating dirt through the hose 507 connected in the connecting hole 508, and discharge the dirt into the sewage tank 512 through the sewage pipe 511. When the dirt floating on the front side of the trash rack 2 is discharged, the second motor 509 is started again to drive the second movable member 504 to the bottom of the canal 1, and the sludge pushed by the propulsion frame 415 is sucked in through the hose 507, thereby cleaning the sludge deposited on the front side of the bottom of the trash rack 2.

[0029] In another embodiment provided by the present invention, Fig.10 and 11 As shown, the adjustment mechanism 6 includes a slide rail 601, which is fixedly installed on the top of the mounting frame 3, and the slide rail 601 is symmetrically arranged on the left and right. A movable platform 603 is movably installed on the slide rail 601 through a movable rod 602. A connecting plate 604 is correspondingly arranged at the top of the mounting frame 3 and at the front and rear of the middle of the slide rails 601 on both sides. A third screw rod 606 is rotatably connected between the front and rear connecting plates 604. A third motor 605 for driving the third screw rod 606 to rotate is fixedly installed on the rear connecting plate 604. The external thread of the third screw rod 606 is connected to a third movable member 607, and the third movable member 607 is fixedly connected to the bottom of the movable platform 603.

[0030] In this solution, the third motor 605 drives the third screw rod 606 to rotate, so that the third movable member 607 moves along the axial direction of the third screw rod 606. The third movable member 607 is fixedly connected to the moving platform 603, so the moving platform 603 will move with the third movable member 607, and then the position of the first driving mechanism 7 on the moving platform 603 is adjusted.

[0031] In another embodiment provided by the present invention, Fig.10 and 11 As shown, the first driving mechanism 7 includes a mounting seat 701, which is fixedly mounted on the top of the moving platform 603, a reel 702 is mounted on the mounting seat 701, and a fourth motor 703 is fixedly mounted on one side of the mounting seat 701, the output end of the fourth motor 703 is fixedly connected to the reel 702, a steel rope 704 is wound around the outside of the reel 702, a support frame 705 is arranged at the top of the moving platform 603 and at the front side of the mounting seat 701, a rotating wheel 706 is movably mounted on the top of the support frame 705, the steel rope 704 is wound around the rotating wheel 706 and fixedly connected to a dirt blocking plate 708, a fixing piece 707 is arranged between the steel rope 704 and the dirt blocking plate 708, movable wheels 711 are arranged on the upper and lower parts of both sides of the dirt blocking plate 708, a vertical plate 709 is vertically arranged corresponding to the front side of the mounting frame 3, and a sliding groove opening 710 along the direction of the plate body is opened on the vertical plate 709, and the movable wheel 711 cooperates with the sliding groove opening 710.

[0032] In this solution, the fourth motor 703 is started to drive the drum 702 to rotate, so that the steel rope 704 is released around the drum 702. After the steel rope 704 changes direction through the rotating wheel 706, it is connected to the dirt-blocking plate 708 through the fixed part 707. After the first driving mechanism 7 is fine-tuned by the adjusting mechanism 6, the movable wheel 711 is matched with the sliding groove mouth 710, so that the dirt-blocking plate 708 is lowered by using the steel rope 704 to intercept small silt impurities. Among them, it should be specifically explained that the self-locking mechanism is arranged in the drum 702.

[0033] In another embodiment provided by the present invention, Fig.12 and 13 As shown, the second driving mechanism 8 includes a lifting column 801, which is fixedly installed on the front side of the moving platform 603 through a fixing plate 802 provided on the rear side, and the lifting column 801 is symmetrically arranged on the left and right sides, and a linear opening 803 is opened on the front side of the lifting column 801, and the interior of the lifting column 801 is connected to a second connecting rod 804 through the linear opening 803, and the second connecting rod 804 is fixedly connected to a transversely arranged second installation frame 805, and the interior of the second installation frame 805 is rotatably connected to a bidirectional threaded rod 806, and the outer side of the second installation frame 805 is fixedly installed with a fifth motor 807 for driving the bidirectional threaded rod 806 to rotate.

[0034] Furthermore, the second cleaning mechanism 9 includes a movable plate 901, which is threadedly connected to the outer surfaces of both ends of the bidirectional threaded rod 806, and the bottom of the movable plate 901 is rotatably connected to a rotating rod 902, and a plurality of adsorption holes 903 are evenly provided on the outer surface of the rotating rod 902. The outer ring of the movable plate 901 extends outward with a plurality of extension blocks 904, and the ends of the plurality of extension blocks 904 away from the movable plate 901 are fixedly connected with an arc-shaped baffle plate 905, and the inner side of the bottom of the arc-shaped baffle plate 905 is connected with a ring 906, and the ring 906 is sleeved on the bottom of the rotating rod 902.

[0035] In this solution, the second connecting rod 804 is driven to descend to a suitable position by the lifting column 801, thereby driving the second cleaning mechanism 9 to descend, and then the fifth motor 807 is started to drive the bidirectional threaded rod 806 to rotate in the second mounting frame 805. Since the movable plate 901 is threadedly connected to the outer surface of the bidirectional threaded rod 806, as the bidirectional threaded rod 806 rotates, the movable plates 901 on both sides will move oppositely along the axis of the bidirectional threaded rod 806. The movement of the movable plate 901 drives the rotating rod 902 at its bottom to move together. When the rotating rod 902 contacts the water body and rotates, the adsorption holes 903 evenly opened on the outer surface of the rotating rod 902 can adsorb the sludge in the water body, and when the rotating rod 902 rotates in the water, the water flow may adsorb it. An impact force is generated. If this impact force acts directly near the adsorption hole 903, it may weaken or even destroy the adsorption effect. The setting of the arc baffle 905 effectively blocks the water flow that directly impacts the adsorption hole 903, thereby protecting the adsorption process from being disturbed by the water flow. When the adsorption hole 903 is fully adsorbed, the second cleaning mechanism 9 is moved up by the lifting column 801, and then the rotating rod 902 is moved to the two sides of the two-way threaded rod 806 in opposite directions by the fifth motor 807. The sludge in the adsorption hole 903 is thrown out by the rotating rod 902, which is much larger than the rotational torque in the water, thereby further realizing the cleaning of small sludge in the water body and improving the sludge treatment effect. Among them, it should be specifically noted that a polymer adsorption resin is provided in the adsorption hole 903.

[0036] Working principle: The present invention cleans out the dirt stuck on the front side of the trash rack 2 by setting up the cooperation of the first cleaning mechanism 4 and the discharge mechanism 5, and the first cleaning mechanism 4 can penetrate into every gap of the trash rack 2 to remove the dirt such as sludge and impurities attached to the rack plate, so that the sludge and other impurities on the trash rack 2 are cleaned. Through the action of water flow, some small sludge impurities will pass through the trash rack 2. Therefore, the first driving mechanism 7 is provided to intercept the small sludge, and then the second driving mechanism 8 and the second cleaning mechanism 9 are provided to make the small sludge piled on the front side of the trash plate 708 adsorbed by the adsorption hole 903, and then the sludge adsorbed on the second cleaning mechanism 9 is cleaned out by cooperating with the second driving mechanism 8, thereby realizing the comprehensive cleaning and optimization of sludge and impurities in the water body, which is helpful to promote water conservancy, environmental protection and sustainable development.
