Description

Technical Field

[0001] This invention relates to the field of trash rack technology, and in particular to an anti-jamming rotary trash rack filter device. Background Technology

[0002] A trash rack is a fence-like structure installed at the inlet of a water conservancy project, hydropower station, or pumping station. It typically consists of metal bars, a frame, and a cleaning device. Its main function is to intercept floating debris, suspended solids, and various other contaminants (such as branches, weeds, garbage, and ice floes) in the water flow. By intercepting floating debris, it prevents them from entering water conveyance structures such as water diversion tunnels and pressure pipelines, thus maintaining flow capacity and ensuring the normal operation of power generation and water supply functions. It also improves water quality to a certain extent through preliminary filtration. To prevent these floating debris from clogging the inlet and affecting water intake capacity, existing trash racks need to be cleaned regularly to avoid debris accumulation and blockage, which would impede water flow.

[0003] A search revealed Chinese invention patent CN121205133B, which discloses a hydraulic debris barrier device. The device includes a channel, a debris barrier fixed within the channel, and a collection mechanism located on one side of the debris barrier. Two opposing mounting plates are fixed to the top of the channel, each equipped with a traction component. Slide assemblies are located on the inner walls of both mounting plates. A cleaning mechanism and a filter mechanism connected to the cleaning mechanism are located within the channel. In this hydraulic debris barrier device, when accumulated debris needs to be cleared, the traction component pulls the cleaning mechanism upwards along the slide assemblies, clearing the debris from the water surface. During this process, the filter mechanism intercepts debris flowing below the cleaning mechanism, preventing it from accumulating at the debris barrier. Furthermore, the filter mechanism assists the cleaning mechanism in pouring the debris into the collection mechanism.

[0004] Existing debris-blocking devices mostly adopt static debris-blocking structures, relying solely on the screen to passively intercept debris. Large floating debris and solid waste easily accumulate at the inlet, causing blockage of the inlet channel and reduction of flow rate. Furthermore, traditional cleaning transmission structures have insufficient torque and poor operational stability, easily leading to transmission slippage and discontinuous cleaning. In addition, traditional fixed screen structures have fixed gaps and no adaptive adjustment capability. Under fluctuating water flow velocity conditions, small debris and flocculent dirt are easily stuck between the screen gaps and cannot be released on their own, which can cause screen blockage and equipment overload shutdown. At the same time, the screens are mostly fixed installations, making disassembly, cleaning, and replacement difficult after blockage and siltation, resulting in maintenance dead zones and high maintenance costs.

[0005] Therefore, the existing anti-jamming rotary trash rack filter device cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an anti-jamming rotary trash rack filter device, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

The outer surface of the reciprocating rod is provided with reciprocating threads. The reciprocating rod passes through the adjusting block and is threadedly connected. A reciprocating motor is fixedly connected to the rear end of the mounting frame located at the lower part of the reciprocating rod. The lower end shaft of the reciprocating rod is fixedly connected to the output end of the reciprocating motor.

[0012] Preferably, the transverse grid includes a limiting frame fixedly connected to the middle of the inner cavity of the first mounting frame. The limiting frame is movably engaged with the second mounting frame on one side of the water inlet end. A longitudinal dividing grid is fixedly connected to the middle of the inner cavity of the second mounting frame. A retractable grid is symmetrically and uniformly rotated and connected to the inner cavity of the second mounting frame with the longitudinal dividing grid as the center line. A micro-motion structure matching the retractable grid is rotatably connected to the upper end of the second mounting frame.

[0013] Preferably, the micro-motion structure includes a transmission link symmetrically rotatably connected to the upper end of the mounting frame two with the longitudinal dividing grid as the neutral line. The upper end of the retracting grid has a rotating shaft that passes through the mounting frame two and is fixedly connected to the transmission link. A transmission rod is rotatably connected to the upper end of the transmission link away from the retracting grid. A spring is connected between the two transmission rods.

[0014] Preferably, the cleaning structure includes two pulleys symmetrically rotatably connected to the mounting frame on one side of the water inlet end. The two pulleys are inclined and a belt is driven to the outer surface of the two pulleys. Water-permeable grooves are evenly opened on the outer surface of the belt. A cleaning plate is evenly fixedly connected to the outer surface of the belt. The outer surface of the cleaning plate is specifically provided with anti-slip texture.

[0015] Preferably, the cleaning drive structure includes a worm gear rotatably connected to the lower front end of the mounting frame, a shaft at the front end of the lower pulley passing through the mounting frame and fixedly connected to the worm gear, a worm being rotatably connected to the front end of the mounting frame located below the worm gear via a bracket, the worm gear and the worm meshing with each other, a cleaning motor being fixedly connected to the front end face of the mounting frame located on one side of the worm, and a shaft on one side of the worm being fixedly connected to the cleaning motor.

[0016] Preferably, the waste storage structure includes rollers slidably connected to the inner cavity of the guide groove, a storage rack is fixedly connected between the two rollers via a coupling, a connecting cable is driven between one side of the storage rack and the reversing shaft, and the inner cavity of the connecting cable matches the cleaning plate.

[0017] The present invention has the following beneficial effects:

[0018] 1. This invention utilizes a front-mounted active cleaning mechanism with a worm gear and belt drive. Traditional debris-blocking devices are mostly static and passive, easily accumulating floating debris at the inlet, causing flow channel blockage and unstable flow. Furthermore, conventional transmissions have poor resistance to load interference and are prone to slippage and jamming. This invention leverages the speed reduction, torque increase, and self-locking stability of the worm gear to drive the belt and cleaning plate in a cyclical motion, actively scraping away and collecting large solid debris and suspended pollutants on the inlet side, achieving graded separation of wastewater. This structure prevents inlet blockage at the source, stabilizes the flow rate, and reduces the load on the downstream filtration system. This invention effectively improves the stability and efficiency of continuous operation of the equipment by adopting a pull-out sludge storage structure with cable reversal and roller guidance. Existing equipment has a fixed sludge storage structure, which requires shutdown and disassembly for sludge removal, resulting in cumbersome maintenance, low efficiency, and high risks of underwater operations. This invention drives the reversing shaft to rotate through cable traction, and with the help of rollers and guide grooves for limiting and guiding, the storage rack can be pulled out and opened smoothly. The equipment can quickly remove sludge without stopping the flow or disassembling the whole machine, reducing equipment start-up and shutdown losses and operating condition fluctuations, significantly reducing maintenance difficulty and operational risks, and extending the continuous operation time of the equipment.

[0019] 2. This invention utilizes a spring-linked adaptive retractable bar anti-jamming mechanism. Traditional fixed bar screens cannot adapt to dynamically changing flow rates, and debris easily gets stuck in the screen gaps, causing downtime. Furthermore, water flow impacts exacerbate bar wear and shorten service life. This invention, through the linkage of the retractable bar screen, transmission link, and telescopic spring, allows the bar screen to adaptively adjust its angle and swing according to the water flow impact force and debris compression force, automatically releasing stuck debris. This solves the hard jamming problem at its structural root. Simultaneously, the spring buffers water flow impact and reduces structural vibration and wear, dynamically adapting to high and low flow rate conditions, balancing filtration accuracy and flow capacity, significantly improving adaptability and structural durability. By adopting a modular bar screen structure with separate limiting assembly, this invention addresses the challenges of disassembling and cleaning existing integrated bar screens, which are difficult, have cleaning dead zones, and require disassembly of core transmission components for maintenance, resulting in high maintenance costs and low efficiency. The combination of the limiting frame and the detachable mounting frame enables independent and rapid disassembly, cleaning, and replacement of the bar screen while ensuring its operational stability and filtration accuracy. This eliminates the need to disturb the core drive transmission structure of the equipment, solving the problems of cumbersome maintenance and incomplete cleaning associated with traditional bar screens. It ensures the long-term stable filtration and anti-clogging performance of the equipment. By configuring a reciprocating dynamic water flow turbulence flushing mechanism, traditional static debris-blocking structures are prone to sediment and scale buildup on the screen surface and in the screen gaps, requiring manual or additional equipment for cleaning and exhibiting poor automated anti-sludge performance. The reciprocating drive component drives the baffle plate to swing at high frequency, dynamically changing the water flow direction and impact angle to form a full-area flushing water flow field, comprehensively removing sediment and dirt from the screen surface and in the screen gaps without the need for additional power equipment or manual intervention. This constructs a long-lasting mechanical self-cleaning system, significantly improving the equipment's anti-sludge and maintenance-free operation capabilities while ensuring filtration accuracy.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] Please see Figure 1-8 As shown, this embodiment is an anti-jamming rotary trash rack filter device, including a base plate 1, an installation structure 2 fixedly connected to the upper end of the base plate 1, a transverse turbulence structure 3 rotatably connected to the inner cavity of the installation structure 2 on the side of the outlet, a reciprocating drive structure 4 provided on the outer surface of the installation structure 2 near the side of the transverse turbulence structure 3, a transverse grid 5 provided in the middle of the inner cavity of the installation structure 2, a micro-motion structure 6 rotatably connected to the upper end of the transverse grid 5, a cleaning structure 7 provided on the inner cavity of the installation structure 2 on the side of the inlet, a cleaning drive structure 8 provided on the front end of the base plate 1 near the cleaning structure 7, and a waste storage structure 9 provided on the upper part of the inner cavity of the installation structure 2 on the side of the inlet.

[0034] Furthermore, the installation structure 2 includes a mounting bracket 21 fixedly connected to the middle of the upper end of the base plate 1. The inner cavity of the mounting bracket 21 has guide grooves 22 on both the front and rear sides of the inner cavity near the water inlet end. The inner cavity of the mounting bracket 21 is rotatably connected to a reversing shaft 23 above the water inlet end. Through the installation structure 2 on the base plate 1, the transverse turbulence structure 3, reciprocating drive structure 4, transverse grille 5, cleaning structure 7, and waste storage structure 9 are installed and placed during use. Then, the guide grooves 22 and the reversing shaft 23 guide and adjust the replacement of the waste storage structure 9.

[0035] Furthermore, the transverse turbulence structure 3 includes a transverse connecting shaft 31 uniformly rotatably connected to the inner cavity of the mounting frame 21 on the side of the outlet. A turbulence plate 32 is symmetrically fixedly connected to the outer surface of the transverse connecting shaft 31. The turbulence plate 32 is made of elastic material. A drive connecting rod 33 that matches the transverse connecting shaft 31 is uniformly rotatably connected to the rear end face of the mounting frame 21. A reciprocating drive structure 4 is provided on the side of the rear end face of the mounting frame 21 near the drive connecting rod 33. The rotating shaft of the rear end face of the transverse connecting shaft 31 passes through the mounting frame 21 and is fixedly connected to the drive connecting rod 33. Through the transverse turbulence structure 3 on the mounting structure 2, the transverse water flow formed by the reciprocating swing of the turbulence plate 32 and the transverse connecting shaft 31 during use can optimize the water flow pattern, reduce the local resistance when the water flows through the device, reduce head loss, avoid the problem of sudden increase in head loss and increased energy consumption caused by siltation in traditional trash racks, and improve the operating efficiency of the entire water conservancy system. It is especially suitable for scenarios such as pumping stations and hydropower stations that are sensitive to head loss.

[0036] Furthermore, the reciprocating drive structure 4 includes a connecting rod 41 rotatably connected to the rear end face of the mounting bracket 21 on one side of the drive link 33. An adjusting block 42 is fixedly connected to the middle of the side of the connecting rod 41 away from the drive link 33. A reciprocating rod 43 is rotatably connected to the rear end of the mounting bracket 21 near the adjusting block 42 via a bracket. The outer surface of the reciprocating rod 43 has reciprocating threads. The reciprocating rod 43 passes through the adjusting block 42 and is threadedly connected. A reciprocating motor 44 is fixedly connected to the rear end of the mounting bracket 21 at the lower part of the reciprocating rod 43. The lower end shaft of the reciprocating rod 43 is fixedly connected to the output end of the reciprocating motor 44. The reciprocating drive structure 4 is driven by the reciprocating... The reciprocating drive structure 4, during use, drives the drive connecting rod 33 to rotate back and forth through the reciprocating rod 43, adjusting block 42, and connecting rod 41, thereby causing the baffle plate 32 and the transverse connecting shaft 31 to swing back and forth, directly changing the direction and angle of water flow and forming a transversely disturbed flow field. This dynamic flow field can continuously flush the grid gaps, preventing the deposition and adhesion of mud, sand, and flocculent dirt at the grid gaps. Furthermore, through the active flushing by transverse turbulence, even with smaller grid gaps, it can effectively prevent clogging, ensuring the interception accuracy of small debris and solving the core contradiction of grid gap clogging, thus achieving a balance between "high-precision debris interception" and "high anti-clogging performance".

[0037] Furthermore, the transverse grille 5 includes a limiting frame 51 fixedly connected to the middle of the inner cavity of mounting frame 1 21. Mounting frame 2 52 is movably engaged with the limiting frame 51 on one side of the water inlet end. A longitudinal dividing grille 53 is fixedly connected to the middle of the inner cavity of mounting frame 2 52. A retractable grille 54 is symmetrically and uniformly rotated within the inner cavity of mounting frame 2 52 about the longitudinal dividing grille 53 as its center line. A micro-movement structure 6, matching the retractable grille 54, is rotatably connected to the upper end of mounting frame 2 52. Through the transverse grille 5 on mounting structure 2, the retractable grille rotates relative to the longitudinal dividing grille 53 during use, achieving left-right swinging of the retractable grille. This "elastic obstacle avoidance" mechanism breaks the traditional "hard-on-hard" interception mode of fixed grilles—when debris gets stuck, the grille actively releases the jamming force through angle micro-adjustment, rather than relying on a rigid structure to forcibly block it, eliminating hard jamming failures from the root of the mechanical structure, especially for small debris such as branches, plastics, and fibers that are easily entangled and jammed.

[0038] Furthermore, the micro-motion structure 6 includes a transmission link 61 symmetrically rotatably connected to the upper end of the mounting frame 52 with the longitudinal dividing grid 53 as the neutral line. The upper end of the retracting grid 54 has a rotating shaft that passes through the mounting frame 52 and is fixedly connected to the transmission link 61. A transmission rod 62 is rotatably connected to the upper end of the transmission link 61 away from the retracting grid 54. A spring 63 is connected between the two transmission rods 62. Through the micro-motion structure 6 on the transverse grid 5, the spring 63 is extended and retracted by the transmission link 61 and the transmission rod 62 during use, which not only realizes the swing of the retracting grid, but also plays a buffering role, absorbing the impact force generated by the squeezing of debris, avoiding deformation and breakage of the grid, transmission link 61 and other components due to rigid stress, reducing equipment wear, extending the service life of key components, reducing equipment failure rate, and reducing downtime maintenance.

[0039] Furthermore, the cleaning structure 7 includes two pulleys 71 symmetrically rotatably connected to the mounting frame 21 on the side of the water inlet. The two pulleys 71 are inclined, and a belt 72 is drivenly connected to the outer surface of the two pulleys 71. The outer surface of the belt 72 is evenly provided with water-permeable grooves, and a cleaning plate 73 is evenly fixedly connected to the outer surface of the belt 72. The outer surface of the cleaning plate 73 is specifically provided with anti-slip texture. Through the cleaning structure 7 on the mounting structure 2, the separated waste is directly introduced into the storage rack 92 by gravity through the cleaning plate 73. Waste collection can be completed without additional power. This not only achieves efficient solid-liquid separation, but also prevents waste from entering the downstream with the water flow, reducing the load on subsequent treatment equipment. At the same time, it prevents waste from lingering and tangling in the inner cavity of the device, further reducing the probability of jamming.

[0040] Furthermore, the cleaning drive structure 8 includes a worm gear 81 rotatably connected to the lower front end of the mounting bracket 21. A shaft at the front end of the lower pulley 71 passes through the mounting bracket 21 and is fixedly connected to the worm gear 81. A worm 82 is rotatably connected to the front end of the mounting bracket 21 below the worm gear 81 via a bracket. The worm gear 81 and the worm 82 mesh with each other. A cleaning motor 83 is fixedly connected to one side of the worm 82 on the front end face of the mounting bracket 21. A shaft on one side of the worm 82 is fixedly connected to the cleaning motor 83. This is achieved through the mounting structure 2. The cleaning drive structure 8 on the top drives the pulley 71 and belt 72 to rotate continuously through the worm gear 81 and worm 82. When water flows through the water permeable channel of belt 72, solid waste is intercepted by the belt. The cleaning plate 73 further separates the waste attached to the surface of the belt, realizing "filtration-separation" at the same time. Compared with the traditional fixed trash rack, the rotational motion breaks the limitations of static interception and avoids solid waste from accumulating on the grid surface to form a "clogging layer", reducing the risk of blockage caused by debris accumulation from the source.

[0041] Furthermore, the waste storage structure 9 includes rollers 91 slidably connected to the inner cavity of the guide groove 22. A storage rack 92 is fixedly connected between the two rollers 91 via a coupling. A connecting cable 93 is connected to one side of the storage rack 92 and the reversing shaft 23. The inner cavity of the connecting cable 93 matches the cleaning plate 73. The reversing shaft 23 drives the rollers 91 to roll, causing the storage rack 92 to slide outward along the guide groove 22, allowing the waste to be directly exposed. Personnel can complete the waste processing without entering the inner cavity of the device. The entire process does not require machine shutdown and does not affect the continuous filtration of the device. It avoids the cumbersome process of traditional trash rack cleaning, which requires machine shutdown and manual cleaning, greatly improving cleaning efficiency and reducing manual labor intensity.

[0042] Working principle:

[0043] During operation, water flows into the inner cavity of the mounting frame 21 through the inlet side. At this time, the cleaning drive structure 8 is activated, causing the output end of the cleaning motor 83 to rotate. As a result, the worm 82 rotates, which in turn meshes with the worm wheel 81, causing the worm wheel 81 to rotate. Since the worm wheel 81 is fixedly connected to the lower pulley 71, the pulley 71 and the belt 72 rotate. When the water flows through the permeable groove on the belt 72, the sewage solid waste is filtered and separated by the belt 72. The waste is further separated from the sewage by the cleaning plate 73 on the outer surface of the belt 72. Then, under the action of gravity, the waste enters the inner cavity of the storage rack 92 after being separated by the cleaning plate 73.

[0044] After the cleaning structure 7 has been working for a certain period of time, the connecting cable 93 is pulled. Since the connecting cable 93 is connected to the outer surface of the reversing shaft 23, the reversing shaft 23 rotates, which further causes the roller 91 to roll. Therefore, the storage rack 92 slides outward along the guide groove 22, which makes it convenient for personnel to carry out subsequent processing of the separated and stored waste.

[0045] Water flowing through the permeable trough enters the inner cavity of the transverse bar 5. When the water flow velocity increases, the retractable bar 54 rotates relative to the longitudinal dividing bar 53, causing the transmission connecting rod 61 to rotate. This causes the two transmission rods 62 on both sides to slide relative to each other, resulting in the extension and retraction of the spring 63. This allows the retractable bar 54 to swing left and right. Simultaneously, due to the left and right swing of the retractable bar 54, when small debris in the sewage squeezes the retractable bar 54, the retractable bar 54 can adaptively and finely adjust its angle, automatically releasing the stuck debris and eliminating hard jamming failures from the root of the mechanical structure. At the same time, personnel can remove the second mounting bracket 52, separating the second mounting bracket 52 from the limiting bracket 51, thus realizing the replacement and cleaning of the transverse bar 5.

[0046] Furthermore, the water flows into the inner cavity of the transverse turbulence structure 3, at which point the reciprocating drive structure 4 is activated, causing the output end of the reciprocating motor 44 to rotate. As a result, the reciprocating rod 43 rotates, causing the adjusting block 42 and the connecting rod 41 to slide up and down under the action of the reciprocating rod 43. This, in turn, causes the drive connecting rod 33 to rotate up and down, which in turn causes the turbulence plate 32 and the transverse connecting shaft 31 to swing back and forth. This achieves the transverse swing of the water flow, thereby changing the direction and angle of the water flow and flushing the grid gaps. This significantly reduces the probability of silt and flocculent debris accumulation, balancing the accuracy of debris interception and the performance of anti-clogging.
