Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and specifically to a trash rack cleaning device for water conservancy projects. Background Technology

[0002] In water conservancy and hydropower projects, it is usually necessary to install trash racks at the inlet of pumping stations and hydropower stations to intercept floating objects such as aquatic plants and garbage carried in the water flow, thereby reducing debris flowing into the waterway.

[0003] Existing trash racks typically consist of a frame, diaphragms, and bars. The ends of the diaphragms and bars are usually set parallel to the frame. When long aquatic plants are blocked by the diaphragms and bars, the two ends of the plants will flow with the water into the other end of the trash rack, causing the plants to get stuck on the rack. This makes cleaning the trash rack troublesome, wastes a lot of manpower, and has low cleaning efficiency.

[0004] The prior art proposes a Chinese patent with publication number CN217781914U to solve the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: A trash rack, belonging to the field of water conservancy engineering technology, to solve the problems of existing trash racks being troublesome to clean, wasting a lot of manpower, and having low cleaning efficiency. It includes a trash rack body, a baffle, a control screw, a sliding block, a scraper, a collection basket, and a connecting plate; the baffle is fixedly connected to the front end of the trash rack body; the control screw is rotatably connected to the front end of the trash rack body; the sliding block is slidably connected to the front end of the trash rack body; and the scraper is rotatably connected to the sliding block. The inner side; the connecting plate is fixedly connected to the left and right end faces of the collection basket; the collection basket is slidably connected to the lower end of the main body of the trash rack; the present invention effectively reduces the cleaning burden of the staff, ensures the interception effect of the trash rack, saves cleaning time, improves cleaning efficiency, and is simple and quick to operate, improving disassembly efficiency. However, its simple hand-cranked scraping cleaning is time-consuming and laborious, and if the scraper used encounters a part with good toughness when scraping up and down, it will cause blockage. Its maintenance is more inconvenient, and the lack of regular maintenance is also an increased risk factor for blockage, which will cause the accumulated suspended matter in the water tank to aggravate the degree of blockage. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning device for trash racks in water conservancy projects to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A cleaning device for a trash rack in water conservancy projects includes a trash rack frame, trash rack bars, a servo motor, serrated hanging strips, a synchronous horizontal plate, a tilting support bar, a tilting shaft, and a controller. The trash rack bars are welded to the inner side of the trash rack frame and are arranged in a plurality of evenly spaced strips. The servo motor is fixedly embedded in both sides of the inner wall of the trash rack frame. The serrated hanging strips are movably installed at the bottom of the synchronous horizontal plate, with one side close to the trash rack bars and fitting against them. The bottom of the serrated hanging strips is serrated. A screw is fixedly installed at the output end of the servo motor via a coupling. The servo motor is electrically connected to the controller via wires. The screw surface is threaded with a drive sleeve at the top. The drive sleeve is welded and fixed to both ends of the synchronous horizontal plate on one side. The two ends of the flip support bar are welded and fixed to the top of the drive sleeve on one side. Mounting shaft brackets are welded to both sides of the top of the flip support bar. The flip shaft is rotatably installed inside the mounting shaft brackets. Several cleaning claws are welded to the surface of the flip shaft. The cleaning claws are evenly distributed and fit with the gap of the trash rack. The controller is fixedly installed on the top side of the trash rack frame. The controller has a built-in time relay and a water flow pressure sensor.

[0008] A flipping drive cleaning mechanism is fixedly installed on one side of the top of the flipping support bar. The flipping drive cleaning mechanism is used to drive the flipping shaft to rotate in both directions.

[0009] A saw tooth drive mechanism is welded to the side of the synchronous horizontal plate away from the trash rack. The saw tooth drive mechanism is used to drive the saw tooth hanging strip to move horizontally to both sides to cut off dirt that is not easy to scrape off.

[0010] A further improvement of the technical solution of the present invention is that: the flip-drive descaling mechanism includes a second motor, a second drive disk, a mounting support frame, a limiting frame, a second drive frame, a mounting strip, a second slide rod, and a reciprocating synchronous assembly. The mounting support frame is fixedly installed on the left side of the flip support strip away from the trash rack strip by bolts. The second drive disk is fixedly installed on the output end of the second motor. The second motor is fixedly installed on the top of the mounting support frame. The second motor is electrically connected to the controller by wires, and its connecting wires are installed through a flexible flexible tube sleeved on the surface. The limiting frame is set on both sides of the second drive disk. The second drive frame is slidably installed on the opposite side of the limiting frame. The slide rod is welded to the side of the second drive frame away from the second motor. The second slide rod is welded to the bottom of the second drive disk away from the second motor. The reciprocating synchronous assembly is set on the side of the mounting support frame close to the flip support strip.

[0011] In the above technical solution, after the second motor starts, it can drive the second drive disk to rotate. The second drive disk drives the second slide rod fixed to it to rotate. When the second slide rod rotates, the second drive frame is limited by the limit frame and then works with the second slide rod to reciprocate up and down. The reciprocating drive of the second drive frame drives the reciprocating synchronous component to rotate the flip shaft.

[0012] A further improvement of the technical solution of the present invention is that: the reciprocating synchronous assembly includes a drive rack limiting unit, gear one, gear two, and a stabilizing shaft frame. The drive rack is detachably mounted on the side away from motor two by bolts. The limiting unit is located on the side of the mounting support frame near the flipping support bar. Gear one is keyed to the surface of the flipping shaft near motor two. Gear two is rotatably mounted inside the mounting shaft frame on the side away from the flipping support bar by a rotating shaft. Gear one meshes with gear two, and gear two meshes with the drive rack. The stabilizing shaft frame is welded to the top of the flipping support bar near gear one and rotates with gear one and gear two.

[0013] Using the above technical solution, the drive rack can move up and down reciprocally following the drive frame 2. After the drive rack moves up and down, it can drive the gear 2 meshing with it to rotate in both directions. Gear 2 drives the gear 1 meshing with it to rotate in both directions. Gear 1 drives the flipping shaft to rotate in both directions continuously. When the flipping shaft rotates in both directions, it can drive the cleaning claw to rotate and cooperate with the cleaning grid to remove dirt from the gaps inside the cleaning grid. At the same time, the stabilizing shaft bracket can cooperate with the mounting shaft bracket to ensure the stability of gear 2 and gear 1 when they rotate.

[0014] A further improvement of the technical solution of the present invention is that: the limiting unit includes a rack limiting frame and a limiting groove. The rack limiting frame is fixed to the side of the flip support bar near the motor two by bolts. The bottom of the limiting frame is welded and fixed to the top two sides of the rack limiting frame. The limiting groove is opened on the side of the rack limiting frame away from the motor two, and the limiting groove slides with the driving rack.

[0015] Using the above technical solution, the rack limit frame can cooperate with the limit rack groove to make the drive rack slide up and down stably, preventing the drive rack from tilting and loosening during continuous flipping, which would cause it to jam with the gear two.

[0016] A further improvement of the technical solution of the present invention is that: the sawtooth drive mechanism includes a support plate, a mounting plate, a motor, a drive disc, a limiting support frame, and a transverse reciprocating linkage assembly. The support plate is welded to the side of the synchronous horizontal plate away from the trash rack. Two limiting support frames are provided, and the two limiting support frames are respectively welded to the top of the support plate away from the trash rack and the top of the synchronous horizontal plate. The mounting plate is welded to the top of the limiting support frame away from the synchronous horizontal plate. The motor is fixedly installed to the mounting plate by bolts. The motor is electrically connected to the controller by wires, and its connecting wires are installed through a flexible conduit sleeve on the surface. The drive disc is fixedly installed at the output end of the motor. The transverse reciprocating linkage assembly is located on the opposite side of the limiting support frame.

[0017] Using the above technical solution, the support plate can provide support for the limiting support frame, and the limiting support frame, together with the mounting plate, can fix the motor one. When the motor one starts, it can drive the drive disk one to rotate. After the drive disk one rotates, it can drive the sawtooth hanging strip to move laterally back and forth through the transverse reciprocating linkage component to cut off the dirt.

[0018] A further improvement of the technical solution of the present invention is that: the transverse reciprocating linkage assembly includes a slide rod, a drive frame, and a connecting plate. The slide rod is welded to one side of the bottom of the drive disc. The drive frame is slidably installed on the opposite side of the limiting support frame, and the interior of the drive frame slides in cooperation with the surface of the slide rod. The top of the connecting plate is welded and fixed to the bottom of the drive frame near the synchronous horizontal plate. The connecting plate is slidably installed in the slot of the synchronous horizontal plate. The bottom of the connecting plate is detachably installed to the top of the serrated hanging strip by bolts.

[0019] In the above technical solution, the slide bar can rotate with the drive disc. When the slide bar rotates, the drive frame can be driven to move left and right by the slide bar through the limit support frame. The drive frame can drive the connecting plate to move along with it, and the connecting plate drives the serrated hanging strip to move laterally.

[0020] A further improvement of the technical solution of the present invention is that: an air jet is provided inside the cleaning claw, and the side of the cleaning claw away from the dirt-blocking grid bar is connected to an external air source through an air pipe connector.

[0021] Using the above technical solution, the jet nozzle can be electrically controlled to spray air through an external air source and an external solenoid valve connected via an air pipe, thereby removing dirt from the inside of the cleaning claw through the jet nozzle.

[0022] A further improvement of the technical solution of the present invention is that: limit blocks are welded to both sides of the top of the serrated hanging strip, and slide bars are welded to the opposite side of the limit blocks; anti-fall blocks are welded to both sides of the bottom of the synchronous horizontal plate, and the anti-fall blocks slide in cooperation with the slide bars.

[0023] Using the above technical solution, the limiting block can make the serrated hanging strip more stable when it moves back and forth by sliding with the sliding strip and the anti-falling block, and will not shake or tilt at both ends. In addition, the serrated bottom can improve the efficiency of cutting off the dirt wrapped around the surface of the trash rack.

[0024] A further improvement to the technical solution of the present invention is that the cleaning method includes the following steps;

[0025] S1, through the preset start time of the controller's built-in time relay, sets a time threshold for timed start. When the time threshold is reached, the servo motor, motor two, and motor one pair start the dirt-blocking grid bars for cleaning.

[0026] S2 connects to the water flow pressure sensor via the controller, and the water flow pressure sensor monitors the water flow pressure status in real time. The maximum threshold of the water flow pressure sensor is set, and when the pressure threshold is reached, the servo motor, motor two, and motor one pair start the trash rack bars for cleaning.

[0027] S21, when the servo motor, motor 2 and motor 1 are started by reaching the maximum pressure threshold, the next start time in step S1 is reset;

[0028] S3, after the servo motor starts, it drives the screw to rotate and drive the drive screw sleeve up and down. When the drive screw sleeve moves, it drives the synchronous horizontal plate and the flip support bar to move synchronously.

[0029] S4, start motor two, drive drive disk two to rotate and drive slide rod two in a ring. The slide rod two driven in a ring is limited by drive frame two and then moves up and down. The up and down drive frame two drives drive rack to move up and down. Drive rack drives gear two to rotate. Gear two drives gear one to rotate. Gear one drives flip shaft to flip. The flip shaft drives dirt removal claw to flip and clean the gaps of dirt barrier.

[0030] S41, the flip-up cleaning claws connect to an external air source through internal air nozzles to perform air cleaning and remove cut residue.

[0031] S5, the start motor drives the drive disc to rotate, the drive disc drives the slide bar to rotate as well. When the slide bar rotates, the drive frame slides with it and is limited by the limit support frame to move left and right back and forth. The reciprocating drive frame drives the connecting plate to move back and forth. The connecting plate drives the serrated hanging strip to move back and forth to cut and remove the dirt on the surface of the trash rack, ensuring its cleaning effect. At the same time, the high-speed reciprocating movement can shake off the dirt to prevent it from continuing to stick.

[0032] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0033] 1. This invention provides a cleaning device for trash racks in water conservancy projects. It comprises a trash rack frame, trash rack bars, a servo motor, serrated hanging bars, a synchronous horizontal plate, a flip support bar, a flip shaft, a controller, a flip drive cleaning mechanism, and a serrated drive mechanism. The flip drive cleaning mechanism drives the flip shaft to rotate in both directions, working with the cleaning claws to remove dirt from the gaps in the trash rack bars. The serrated drive mechanism drives the serrated hanging bars to continuously move laterally to cut off dirt that is difficult to scrape off. Simultaneously, the servo motor enables the cleaning structure to move up and down for cleaning operations. This solves the problem of the simple hand-cranked scraping cleaning method proposed in the prior art, which is time-consuming and labor-intensive. Furthermore, the scraper used in that method may become stuck when encountering a tough section during up-and-down scraping, making maintenance more inconvenient. The lack of regular maintenance also increases the risk of clogging, leading to the accumulation of suspended matter in the water tank, which exacerbates the clogging.

[0034] 2. This invention provides a cleaning device for trash racks in water conservancy projects. By setting up a second motor, a second drive disc, a mounting support frame, a limiting frame, a second drive frame, a mounting strip, a second slide rod, and an up-and-down reciprocating synchronous assembly, the second motor can drive the second drive disc to rotate after starting. The second drive disc drives the slide rod, which is fixed to it, to rotate. When the slide rod rotates, the second drive frame, after being limited by the limiting frame, cooperates with the slide rod to perform up-and-down reciprocating drive. The reciprocating drive of the second drive frame drives the up-and-down reciprocating synchronous assembly to rotate the flipping shaft.

[0035] 3. This invention provides a cleaning device for trash racks in water conservancy projects. By setting up a support plate, a mounting plate, a motor, a drive disc, a limiting support frame, and a transverse reciprocating linkage assembly, the support plate can provide support for the limiting support frame. At the same time, the limiting support frame, together with the mounting plate, can fix the motor. When the motor starts, it can drive the drive disc to rotate. After the drive disc rotates, it can drive the sawtooth hanging strip to move laterally back and forth through the transverse reciprocating linkage assembly to cut off the dirt.

[0044] The present invention will be further described in detail below with reference to embodiments:

[0045] Example 1

[0046] like Figure 1-7As shown, this invention provides a cleaning device for a trash rack in water conservancy projects, including a trash rack frame 1, trash rack bars 2, a servo motor 3, serrated hanging bars 4, a synchronous horizontal plate 5, a flipping support bar 6, a flipping shaft 7, and a controller 9. The trash rack bars 2 are welded to the inner side of the trash rack frame 1 and are arranged in a plurality of equally spaced positions. The servo motor 3 is fixedly embedded in both sides of the inner wall of the trash rack frame 1. The serrated hanging bars 4 are movably installed at the bottom of the synchronous horizontal plate 5, and are close to the trash rack bars 2 on the side closest to them. The bottom of the serrated hanging bars 4 is serrated. Limiting blocks 41 are welded to both sides of the top of the serrated hanging bars 4, and sliding strips 42 are welded to the opposite sides of the limiting blocks 41.

The two ends of the flip support bar 6 are welded and fixed to the top of the side of the drive screw sleeve 32 that is close to the two ends. The top two sides of the flip support bar 6 are welded with mounting brackets 87. The flip shaft 7 is rotatably installed inside the mounting brackets 87. Several cleaning claws 71 are welded on the surface of the flip shaft 7. The cleaning claws 71 have air nozzles 711 inside. The side of the cleaning claws 71 away from the trash rack 2 is connected to an external air source through an air pipe connector. Several cleaning claws 71 are evenly distributed and match the gap of the trash rack 2. The controller 9 is fixedly installed on the top side of the trash rack frame 1. The controller 9 has a built-in time relay and a water flow pressure sensor.

[0047] A tilting drive descaling mechanism is fixedly installed on one side of the top of the tilting support bar 6. The tilting drive descaling mechanism includes a second motor 8, a second drive disc 81, a mounting support frame 82, a limit frame 83, a second drive frame 84, a mounting bar 841, a second slide bar 85, and an up-and-down reciprocating synchronous assembly. The mounting support frame 82 is fixedly installed on the left side of the tilting support bar 6 away from the trash rack bar 2 by bolts. The second drive disc 81 is fixedly installed on the output end of the second motor 8. The second motor 8 is fixedly installed on the top of the mounting support frame 82. The second motor 8 is connected to the controller 9 via wires. The connection is made so that the connecting wires are installed through a flexible flexible tube sleeved on the surface. The limiting frame 83 is set on both sides of the drive plate 81. The drive plate 84 is slidably installed on the opposite side of the limiting frame 83. The mounting strip 841 is welded to the side of the drive plate 84 away from the motor 8. The slide rod 85 is welded to the bottom of the drive plate 81 away from the motor 8. The up-and-down reciprocating synchronous assembly is set on the side of the mounting support frame 82 near the flipping support strip 6. The up-and-down reciprocating synchronous assembly includes a drive rack 86, a limiting unit gear 871, a gear 872, and a stabilizing unit. The shaft bracket 873 includes a limiting unit comprising a rack limiting bracket 861 and a limiting groove 862. The rack limiting bracket 861 is bolted to the side of the flip support bar 6 near the motor 8. The bottom of the limiting frame 83 is welded to the top sides of the rack limiting bracket 861. The limiting groove 862 is located on the side of the rack limiting bracket 861 away from the motor 8, and the limiting groove 862 slides with the drive rack 86. The drive rack 86 is detachably mounted on the side of the mounting bar 841 away from the motor 8 by bolts. The limiting unit is located on the mounting support bracket. On the side of the flip support bar 6, gear 871 is keyed to the surface of the flip shaft 7 on the side near the motor 8. Gear 872 is rotatably mounted inside the mounting bracket 87 on the side away from the flip support bar 6 via a rotating shaft. Gear 871 meshes with gear 872, and gear 872 meshes with the drive rack 86. The stabilizing bracket 873 is welded to the top of the flip support bar 6 on the side near gear 871 and rotates with gear 871 and gear 872. The flip drive cleaning mechanism is used to drive the flip shaft 7 to rotate in both directions.

[0048] A saw tooth drive mechanism is welded to the side of the synchronous horizontal plate 5 away from the trash rack 2. The saw tooth drive mechanism is used to drive the saw tooth hanging strip 4 to move horizontally to both sides to cut off dirt that is not easy to scrape off.

[0049] In this embodiment, the flip-drive dirt removal mechanism drives the flip shaft 7 to rotate in both directions to cooperate with the dirt removal claw 71 to remove dirt from the gaps in the dirt-blocking grid 2. The saw tooth drive mechanism drives the saw tooth hanging bar 4 to continuously move laterally to cut off dirt that is difficult to scrape off. Simultaneously, the servo motor 3 is activated to perform up-and-down cleaning operations on the aforementioned cleaning structure. After the second motor 8 is started, it drives the second drive disk 81 to rotate. The second drive disk 81 drives the slide rod 85, which is fixed to it, to rotate. When the slide rod 85 rotates, the second drive frame 84, after being limited by the limit frame 83, cooperates with the slide rod 85 to perform up-and-down reciprocating drive. The reciprocating drive of the second drive frame 84, through the mounting strip 841, drives the up-and-down reciprocating synchronous component to rotate the flip shaft 7. The drive rack 86 can follow the second drive frame 84 to move up and down reciprocally through the mounting strip 841. After the drive rack 86 moves up and down, it drives the gear 872 meshing with it to rotate in both directions. The gear 872 drives the gear 871 meshing with it to rotate in both directions. Wheel 871 drives the rotating shaft 7 to continuously rotate in both directions. During this rotation, the rotating shaft 7 drives the cleaning claw 71 to rotate and cooperate with the dirt-blocking grid 2 to remove dirt from the gaps inside the grid 2. Simultaneously, the stabilizing shaft bracket 873, in conjunction with the mounting shaft bracket 87, ensures the stability of the rotation of gear 872 and gear 871. The rack limiting bracket 861, in conjunction with the limiting groove 862, stabilizes the up-and-down sliding of the drive rack 86, preventing it from tilting or loosening during continuous rotation, thus avoiding contact with... Gear 2 872 is interlocked and locked. The jet nozzle 711 can achieve electric control of jet operation by connecting an external air source and an external solenoid valve through an air pipe. The jet nozzle 711 sprays away the dirt inside the cleaning claw 71. The limit block 41 can slide and connect with the slide bar 42 and the anti-drop block 43, making the serrated hanging bar 4 more stable when it moves back and forth, and preventing the ends from shaking or tilting. In addition, the serrated bottom can improve the efficiency of cutting off the dirt wrapped around the surface of the dirt barrier bar 2.

[0050] Example 2

[0051] like Figure 1-7As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the sawtooth drive mechanism includes a support plate 51, a mounting plate 52, a motor 53, a drive disc 54, a limiting support frame 57, and a transverse reciprocating linkage assembly.

Two limiting support frames 57 are provided, and the two limiting support frames 57 are respectively welded to the top of the support plate 51 away from the trash rack 2 and the top of the synchronous horizontal plate 5. The mounting plate 52 is welded to the top of the limiting support frame 57 away from the synchronous horizontal plate 5. The motor 53 is fixedly installed to the mounting plate 52 by bolts. The motor 53 is electrically connected to the controller 9 by wires, and its connecting wires are... The drive disc 54 is fixedly installed at the output end of the motor 53 by means of a flexible flexible sleeve on the surface. The transverse reciprocating linkage assembly is set on the opposite side of the limit support frame 57. The transverse reciprocating linkage assembly includes a slide rod 55, a drive frame 58 and a connecting plate 56. The slide rod 55 is welded to one side of the bottom of the drive disc 54. The drive frame 58 is slidably installed on the opposite side of the limit support frame 57, and the interior of the drive frame 58 slides in cooperation with the surface of the slide rod 55. The top of the connecting plate 56 is welded and fixed to the bottom of the drive frame 58 near the synchronous horizontal plate 5. The connecting plate 56 is slidably installed in the slot of the synchronous horizontal plate 5. The bottom of the connecting plate 56 is detachably installed to the top of the serrated hanging strip 4 by bolts.

[0052] In this embodiment, the support plate 51 can provide support for the limiting support frame 57. At the same time, the limiting support frame 57, together with the mounting plate 52, can fix the motor 53. When the motor 53 starts, it can drive the drive disk 54 to rotate. After the drive disk 54 rotates, it can drive the serrated hanging strip 4 to move laterally back and forth through the lateral reciprocating linkage component to cut off the dirt. The slide rod 55 can follow the rotation of the drive disk 54. When the slide rod 55 rotates, the drive frame 58 can be driven left and right by the slide rod 55 through the limitation of the limiting support frame 57. The lateral reciprocating drive frame 58 can drive the connecting plate 56 to move accordingly. The connecting plate 56 drives the serrated hanging strip 4 to move laterally back and forth.

[0053] The cleaning method includes the following steps;

[0054] S1, by using the preset start time of the built-in time relay of the controller 9, a time threshold for timed start is set. When the time threshold is reached, the servo motor 3, motor 8 and motor 53 are started to clean the trash rack 2.

[0055] S2, the controller 9 connects to the water flow pressure sensor, and the water flow pressure sensor monitors the water flow pressure status in real time. The maximum threshold of the water flow pressure sensor is set. When the pressure threshold is reached, the servo motor 3, motor 8 and motor 53 are started to clean the trash rack 2.

[0056] S21, when the servo motor 3, motor 2 8 and motor 1 53 are started by reaching the maximum pressure threshold, the next start time in step S1 is reset;

[0057] S3, after the servo motor 3 starts, the servo motor 3 drives the screw 31 to rotate, which drives the drive screw sleeve 32 up and down. When the drive screw sleeve 32 moves, it drives the synchronous horizontal plate 5 and the flip support bar 6 to move synchronously.

[0058] S4, start motor 2 8, drive drive disk 2 81 to rotate and drive slide bar 2 85 in a ring. The slide bar 2 85 driven in a ring is limited by drive frame 2 84, which is limited by limit frame 83 and moves up and down. Drive frame 2 84 moves up and down through mounting strip 841 and drives drive rack 86 to move up and down. Drive rack 86 drives gear 2 872 to rotate. Gear 2 872 drives gear 1 871 to rotate. Gear 1 871 drives flip shaft 7 to flip. The flip shaft 7 drives dirt-removing claw 71 to flip and clean the gaps of dirt-blocking grid bar 2.

[0059] S41, the flipped cleaning claw 71 connects to an external air source through an internal air nozzle 711 to perform air cleaning and remove cut residue.

[0060] S5, the start motor 53 drives the drive disc 54 to rotate, the drive disc 54 drives the slide bar 55 to rotate as well. When the slide bar 55 rotates, the drive frame 58 slides with it and is limited by the limit support frame 57 to move left and right back and forth. The reciprocating drive frame 58 drives the connecting plate 56 to move back and forth. The connecting plate 56 drives the serrated hanging strip 4 to move back and forth to cut and remove the dirt on the surface of the trash rack 2, ensuring its cleaning effect. At the same time, the high-speed reciprocating movement can shake off the dirt to prevent it from continuing to stick.

[0061] The working principle of the trash rack cleaning device used in this water conservancy project will be explained in detail below.

[0062] like Figure 1-7As shown, the controller 9 has a built-in time relay with a preset start time. A time threshold is set for the start time. When the threshold is reached, servo motors 3, 8, and 53 are activated to clean the debris rack 2. After servo motor 3 starts, it drives the screw 31 to rotate, which in turn drives the drive sleeve 32 up and down. As the drive sleeve 32 moves, it drives the synchronous horizontal plate 5 and the flip support bar 6 to move synchronously. Simultaneously, motor 53 starts, driving the drive disc 54 to rotate. The rotation of drive disc 54 drives the slide bar 55 to rotate. When slide bar 55 rotates, drive frame 58 is limited by the limit support frame 57 and moved by slide bar 55 for left-right reciprocating drive. The reciprocating drive frame 58 drives the connecting plate 56 to move accordingly. The connecting plate 56 drives the serrated hanging strip 4 to reciprocate laterally, cutting the dirt below and preventing further accumulation and entanglement. Then, motor 8 starts... Then, motor 28 drives drive disk 281 to rotate through its output end, which in turn drives slide bar 285 in a ring. The slide bar 285 driven in a ring is limited by drive frame 284, which is then limited by limit frame 83 and moves up and down. Drive frame 284 moves up and down through mounting strip 841, which drives drive rack 86 to move up and down. Drive rack 86 drives gear 2872 to rotate, gear 2872 drives gear 1871 to rotate, gear 1871 drives flip shaft 7 to flip, and flipping shaft 7 drives cleaning claw 71 to flip and clean the gaps of the debris barrier 2. The flipping cleaning claw 71 is connected to an external air source through internal air nozzle 711 and is opened by an external solenoid valve that controls the air source to perform air cleaning, removing the cut residue and ensuring the cleaning efficiency of debris barrier 2. When the water flow pressure sensor pressure threshold is too high, servo motor 3, motor 28 and motor 153 are started to clean debris barrier 2.

[0063] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
