Description

Technical Field

[0001] This invention belongs to the technical field of animal husbandry drinking water, specifically a mechanical scraper cleaning device for animal husbandry drinking troughs. Background Technology

[0002] As the name suggests, livestock water troughs are devices specifically designed to provide drinking water for farmed animals such as pigs, cattle, sheep, and poultry. They have evolved from simple "water containers" into comprehensive systems integrating water supply, cleaning, purification, and animal behavior management. Cleaning water troughs is not merely "hygiene," but a core aspect of farm biosecurity, production efficiency, and animal welfare for the following reasons: Ensuring animal health and preventing disease outbreaks: Residual feed, saliva, feces, hair, and other organic matter decompose rapidly in warm water, providing an ideal breeding ground for bacteria (such as E. coli and Salmonella), viruses, and parasites. Animals drinking contaminated water can directly lead to large-scale outbreaks of digestive tract diseases and parasitic diseases. Therefore, cleaning water troughs is essential.

[0003] The prior art discloses a Chinese patent with application number CN220476599U, which discloses a drinking water device for cattle farming. It discloses that when the cattle need to drink water, the main valve on the water injection pipe is opened, and the water injection pipe injects water into the drinking trough. When the water in the drinking trough overflows the float through the connecting pipe, the float is no longer buoyant. Under the action of gravity, the float moves downward through the spring, thereby causing the water injection pipe to start injecting water again. This realizes automatic water injection into the drinking trough, thus avoiding the consumption of a lot of labor.

[0004] While the aforementioned device can provide drinking water for farmed animals, it still has some drawbacks: 1. When animals drink water, impurities and feed adhering to their mouths will fall into the water along with the animals. If not treated, the feed and impurities that fall into the water will affect the water quality when soaked in the water, thus deteriorating the water quality environment in the drinking trough.

[0005] 2. Existing technologies mostly require manual or additional electronic control for cleaning water troughs, making it inconvenient to perform the work while animals are drinking. Summary of the Invention

[0006] The purpose of this invention is to provide a mechanical scraper-type cleaning device for aquaculture drinking troughs to solve the problems mentioned in the background art.

[0007] The objective of this invention can be achieved through the following technical solutions: A mechanical scraper-type cleaning device for aquaculture drinking troughs includes a stabilizing frame with symmetrical trough boxes on both sides. A front box communicating with the inner cavity of the trough box is fixedly installed on the front side of the trough box. A filter plate that slides inside the trough box is installed in the middle of the trough box through an adjustment unit. Cleaning boxes are symmetrically arranged on both sides of the trough box. A rear box communicating with the stabilizing frame is located on the rear side of the trough box. A discharge unit is located in the rear box. A water supply pipe is installed between the two front boxes. A water supply tank is connected to the lower middle side of the water supply pipe. A drain pipe is also provided on the trough box. Two sets of symmetrically arranged guide rods are located below the filter plate in the inner cavity of the trough box. Multiple sets of U-shaped frames are slidably installed between the two sets of guide rods. An activated carbon plate is located in the middle of the U-shaped frame. A brush frame is detachably installed on the outside of the U-shaped frame. A rotating rod is rotatably installed in the middle of the front box. Multiple circumferentially arranged blades are fixed on the outside of the rotating rod. The two sides of the rotating rod are also automatic adjustment units for adjusting the spacing between the multiple U-shaped frames.

[0008] Preferably, the control unit includes four outer edge boxes that are connected to the tank. An L-shaped plate in an inverted L-shape is slidably installed inside the outer edge box. The bottom of the multiple L-shaped plates is detachably connected to the filter plate. A positioning plate that slides inside the outer edge box is provided at the bottom of the L-shaped plate. A spring is installed between the positioning plate and the L-shaped plate. A moving rod that passes through and slides on the bottom of the outer edge box is fixedly installed at the bottom of the positioning plate.

[0009] Preferably, the bottom of multiple moving rods is jointly mounted with an external frame surrounding the outside of the tank, and a cylinder is jointly mounted between the connection point of the external frames outside the two tanks and the stabilizing frame.

[0010] Preferably, the discharge section includes a trapezoidal block fixed to the center of the rear box cavity. The trapezoidal block has symmetrically arranged vertical grooves on the side near the rear box. A symmetrically arranged slide frame is vertically slidably installed in the two vertical grooves. A wedge block that fits the trapezoidal block is horizontally slidably installed in the slide frame. A symmetrically arranged curved rod is installed on the end of each of the two wedge blocks away from the slide frame. A mutually symmetrical external component is installed on each of the two curved rods. A spring is installed between the two external components.

[0011] Preferably, a cleaning plate is fixedly installed at the end of the curved rod away from the wedge block. The two cleaning plates are set with their opposite sides at an angle. A baffle plate is also provided above the cleaning plate. The bottom of the baffle plate is set with an angle. A T-shaped plate with an inverted T-shape is fixed to the inner cavity of the tank above the baffle plate. A spring is slidably installed on the outside of the T-shaped plate and is installed together with the T-shaped plate. A fixing plate is fixedly installed on the bottom side of the fixing plate. The bottom of the fixing plate is fixedly connected to the baffle plate.

[0012] Preferably, a central component is fixedly installed in the middle of the U-shaped frame, and an installation groove is formed at the top of the central component. When the activated carbon plate is located in the installation groove, it is installed on the U-shaped frame. Water-draining holes are also provided on both sides of the activated carbon plate.

[0013] Preferably, the automatic control unit includes take-up and release wheels located on both sides of the blade and fixed to the rotating rod. The take-up and release wheel has a guide wheel that is rotatably connected to the inner wall of the front box on the side of the take-up and release wheel near the tank. A vertical rod is fixedly installed on the side of the guide wheel away from the take-up and release wheel. A limiting member is slidably installed on the outside of the vertical rod. A spring is sleeved on the outside of the vertical rod, and one end of the spring is connected to the limiting member.

[0014] Preferably, a slide bar is fixedly installed on one side of the limiting member, and a steel rope is installed between the top of the slide bar and the take-up and release wheel. The section of the steel rope near the take-up and release wheel is dragged and slid on the guide wheel, and a connecting plate is fixedly installed at the bottom of the slide bar.

[0015] Preferably, the automatic control unit further includes side grooves symmetrically opened in the inner cavity of the slot box, an inner plate is slidably installed in the side groove, a spring is provided in the side groove to connect with the top of the inner plate, a side rod located outside the U-shaped frame is installed between the inner plate and the corresponding connecting plate, and a positioning member fixed to the side rod is provided between two adjacent U-shaped frames, and two inclined plates in a V-shape are rotatably installed on the positioning member and are hinged to the two adjacent U-shaped frames.

[0016] Preferably, when replacing the activated carbon plate during use, the filter plate can be disassembled to open the upper part of multiple U-shaped frames, so as to facilitate the replacement of the activated carbon plate.

[0017] The beneficial effects of this invention are: 1. This invention, when the cylinder extends and retracts, drives the external frame to rise and fall, adjusting the elasticity range of the spring above the positioning plate. When animals drink water and press down on the filter plate, the movement range of the filter plate within the tank is reduced. By moving the filter plate within the tank, different water levels can be achieved to meet the drinking needs of different animals. For young animals with less strength, the elasticity is reduced to decrease the movement range, making it easier to press down the filter plate. For adult livestock, the elasticity is increased to provide sufficient support and rebound force. The final sinking position of the filter plate determines the water depth that the animals can access. By adjusting the movement range, the optimal drinking water level can be actively set, for example, a shallower water level can be set for poultry to prevent drowning or excessive water play.

[0018] 2. This invention achieves its goal by having the filter plate move upwards and reset when the animal finishes drinking. The cleaning plates on both sides then move away from each other on the filter plate, automatically scraping impurities from the filter plate into the cleaning boxes on both sides. The cleaning plates gather in the middle when the filter plate moves downwards and spread out to the sides when it moves upwards, forming a dynamic cleaning area that can effectively handle impurities that fall onto any part of the filter plate when the animal drinks. This avoids the cleaning dead zones that may exist with fixed scrapers. The entire cleaning process of scraping, pushing, and collecting is driven entirely by the animal's natural downward movement while drinking and the upward movement of the filter plate's mechanical reset spring. No sensors, controllers, or external power sources are required. This passive triggering mechanism ensures that the cleaning action is seamlessly connected and completed synchronously with the animal's drinking behavior.

[0019] 3. In this invention, when water enters the front chamber and impacts the blades, the blades drive the rotating rod to rotate. As the rotating rod rotates, it simultaneously drives the take-up and release wheels to rotate. When the take-up and release wheels rotate, they pull the sliding rod through the steel cable. The activated carbon plates in multiple central components continuously change position, thereby increasing the frequency of contact with the water in the tank. When the U-shaped frame moves, it can also simultaneously drive the external brush frame to scrape the inner wall of the tank, preventing scale from adhering to the inner wall of the tank. The activated carbon plates constantly change position in the water in the tank, which is equivalent to a continuous and forced "stirring" of the water, ensuring that the water in all areas has the opportunity to fully contact the activated carbon surface.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-12As shown, this invention is a mechanical scraper-type cleaning device for aquaculture drinking troughs, including a stabilizing frame 1. Symmetrical trough boxes 2 are arranged on both sides of the stabilizing frame 1. A front box 20, communicating with the inner cavity of the trough box 2, is fixedly installed on the front side of the trough box 2. A filter plate 21, sliding within the trough box 2, is installed in the middle of the trough box 2 via an adjustment mechanism. Symmetrically arranged cleaning boxes 22 are provided on both sides of the trough box 2. A rear box 23, communicating with the stabilizing frame 1, is provided on the rear side of the trough box 2. A discharge section is provided inside the rear box 23. A water supply pipe 31 is installed between the two front boxes 20. A water supply tank 3 is connected to the lower middle part of the tank 1. A drain pipe is also provided on the tank 2. The inner cavity of the tank 2 is provided with two sets of symmetrically arranged guide rods 5 located below the filter plate 21. Multiple sets of U-shaped frames 51 are slidably installed between the two sets of guide rods 5. An activated carbon plate 53 is provided in the middle of the U-shaped frame 51. A brush holder 59 is detachably installed on the outside of the U-shaped frame 51. A rotating rod 4 is rotatably installed in the middle of the front box 20. Multiple circumferentially arranged blades 41 are fixed on the outside of the rotating rod 4. The two sides of the rotating rod 4 are also automatic control units for adjusting the spacing between multiple U-shaped frames 51.

[0025] During operation: The trough 2 is symmetrically arranged on both sides of the stabilizer 1, which can meet the needs of the farmed animals to drink water in a dispersed manner and avoid crowding when the animals drink. The downward pressure of the filter plate 21 when the animals drink can make the filter plate 21 move down into the water surface when it moves down in the trough 2, so as to facilitate normal drinking for the animals. The filter plate 21 can block other grass and impurities that adhere to the animals' mouths when drinking, and prevent grass and impurities that fall from the animals' mouths when drinking from entering the bottom of the trough 2, thereby affecting the water quality inside the trough 2. The filter plate 21 descends when the animals drink, but always acts as a barrier, which can effectively prevent the animals' mouths and noses from directly contacting the sludge or high-bacterial areas that may be deposited at the bottom of the trough 2, reducing the risk of disease entering through the mouth, and achieving physical isolation of pollutants. With the discharge section in place, after the animals finish drinking, the pressure on the filter plate 21 is released, and as the filter plate 21 rises in the tank 2, the grass and impurities that fall off the filter plate 21 while the animals are drinking can automatically enter the cleaning boxes 22 on both sides of the tank 2. The discharge section, in conjunction with the rise of the filter plate 21, sweeps the impurities into the cleaning boxes 22, thus realizing the automated and timely separation of solid waste, avoiding the long-term soaking and decay of impurities in the water, which would deteriorate the water quality, and achieving automatic sewage discharge and reducing decay. By adjusting the position of the spring below the filter plate 21, the movement range of the filter plate 21 within the tank 2 when it is squeezed can be adjusted, thereby meeting the drinking needs of different types of livestock. The adjustment unit not only adjusts the stroke of the filter plate 21, but also adjusts the "downward pressure" required by the animals when drinking by changing the spring pressure. This can adapt to the different drinking habits of young animals to adult livestock, and avoid the filter plate 21 being too sensitive or sluggish, adapting to different animal habits and body sizes. By disassembling the filter plate 21 as a whole on the control unit, it is easy to remove the filter plate 21 from the tank 2, which in turn facilitates the replacement of the activated carbon plate 53 after a certain period of use, so as to maintain the ability of the activated carbon plate 53 to continuously purify the water in the tank 2 and ensure the drinking water quality of the animals. The external brush holder 59 of the U-shaped frame 51 is "detachable", the filter plate 21 can be "disassembled as a whole", and the activated carbon plate 53 is placed on the U-shaped frame 51. These designs make the replacement, cleaning and maintenance of the core cleaning and purification components very convenient, without the need for professional tools or complicated operations. By opening the water supply tank 3, the water supply pipe 31 can simultaneously supply water to the two tanks 2, thus facilitating the continuous injection of water into the tanks 2. After the water volume in the tanks 2 reaches a certain standard, the drain pipe on the tanks 2 can be opened to circulate the water in the tanks 2, thereby maintaining the flow of water quality in the tanks 2. Continuous or periodic water flow renewal and circulation can inhibit the excessive reproduction of algae and certain bacteria in a stagnant water environment, maintain good sensory properties of the water body, and inhibit microorganisms through water circulation. Water from the water supply tank 3 is injected into the front tank 20 through the water supply pipe 31. Since the front tank 20 is connected to the tank 2, the water in the front tank 20 flows into the tank 2. When the water enters the front tank 20, it impacts the blades 41. The blades 41 rotate when impacted by the water flow, which in turn drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, the automatic control unit can slide multiple U-shaped frames 51 on the guide rod 5. As the multiple U-shaped frames 51 repeatedly move closer or further apart, they can drive the external brush holder 59 to move, thereby automatically cleaning the inner wall of the tank 2. The brush holder 59 reciprocates under the drive of the U-shaped frames 51, achieving a thorough cleaning of the inner wall of the tank 2, especially the inner wall. It features bidirectional scraping of the side walls and bottom, resulting in higher cleaning efficiency than unidirectional motion. By repeatedly scraping the inner wall of the tank 2, it prevents scale buildup and eliminates the need for manual cleaning of the tank 2's interior. The device utilizes the impact of water flow on the blades 41 to drive the rotating rod 4, directly converting the kinetic energy of the water flow into mechanical energy to drive the cleaning mechanism. This eliminates the need for additional electricity or power sources, achieving true energy saving and self-driving, self-powered cleaning. As long as the water supply continues, even in circulation or drip mode, the cleaning action of the brush holder 59 will occur continuously or intermittently. This enables routine, preventative maintenance of the tank walls, preventing the accumulation and hardening of dirt, rather than waiting until it becomes severe before performing high-intensity cleaning, ensuring continuous cleaning.

[0026] The control unit includes four outer edge boxes 211 that are connected to the tank box 2. An L-shaped plate 212 in an inverted L-shape is slidably installed inside the outer edge box 211. The bottom of the multiple L-shaped plates 212 is detachably connected to the filter plate 21. A positioning plate 213 is provided at the bottom of the L-shaped plate 212 and slides inside the outer edge box 211. A spring is installed between the positioning plate 213 and the L-shaped plate 212. A moving rod 214 that passes through and slides at the bottom of the outer edge box 211 is fixedly installed at the bottom of the positioning plate 213.

[0027] When adjusting the movement range of the filter plate 21 in the tank 2, the cylinder 216 is first activated for extension and retraction. When the cylinder 216 pushes downward and forward, it drives the outer frame 215 to move downward. As the outer frame 215 moves downward, it simultaneously drives multiple moving rods 214 on both sides of the tank 2 to slide down. As the moving rods 214 slide down, they simultaneously drive multiple positioning plates 213 inside the outer edge boxes 211 to move downward. When the positioning plates 213 move downward, the range of the spring force above them is increased. When the animal drinks water and presses down on the filter plate 21, the outer edge box 211 increases the range of movement of the filter plate 21 within the tank 2. Conversely, when the cylinder 216 opens and retracts, the cylinder 216 drives multiple moving rods 214 to move upward through the external frame 215. As the moving rods 214 move upward, they simultaneously drive multiple positioning plates 213 within the outer edge box 211 to move upward. As the positioning plates 213 move upward, the elastic force range of the springs on their upper parts decreases. When the animal drinks water and presses down on the filter plate 21... When the outer edge box 211 moves the filter plate 21 within the tank 2, the range of movement is reduced. By moving the filter plate 21 within the tank 2, it can be placed at different water levels to meet the drinking needs of different animals. Through the continuous adjustment of the spring force range by the cylinder 216, the downward pressure of the filter plate can be steplessly and precisely controlled. This perfectly adapts to the drinking needs of livestock throughout their entire growth cycle, from cubs to adults. For young animals with less strength, the spring force is reduced to decrease the range of movement, making it easier for the filter plate to be pressed down and for easy drinking. For adult animals, the spring force is increased to provide sufficient support and rebound force. Through stepless adjustment of young and adult animals, it precisely adapts to animals at different growth stages. For breeds with special drinking habits, such as pigs that like to root, cattle that use their tongues to roll, or breeds with large differences in body size, this system can find the most suitable resistance and stroke of the filter plate 21, improving the comfort and naturalness of animal drinking, reducing insufficient drinking due to maladaptation, and adapting to the habits of special species. The final sinking position of the filter plate 21 determines the water depth that animals can access. By adjusting the range of movement, the optimal drinking water level can be actively set. For example, a shallower water level can be set for poultry to prevent drowning or excessive water play, while a deeper water level can be set for large livestock to meet their single drinking needs. The range of movement of the filter plate 21 can be linked to the water supply and drainage system. When the shallow water level is reduced by adjusting the range of movement, the inlet flow rate of the water supply pipe 31 or the threshold of the water level sensor can be reduced simultaneously to achieve on-demand water supply and reduce water waste. By adjusting the spring preload, the "buffering" force of the filter plate 21 moving downward can be controlled. When faced with animals pressing down violently, such as in a group crowding or when large animals drink impatiently, the strong elasticity can absorb the impact and prevent the filter plate 21 or its connecting mechanism from being damaged by instantaneous overload. During periods when the animals are not drinking, the spring can be adjusted to the maximum preload and minimum movement range through the cylinder 216, keeping the filter plate 21 in the upper locked or slightly moving state. This can prevent erroneous actions caused by wind or small animals touching it, and also reduce the no-load wear of the internal mechanical structure. The bottom of multiple moving rods 214 is jointly mounted with an external frame 215 that surrounds the outside of the tank 2. A cylinder 216 is jointly mounted between the connection point of the external frames 215 outside the two tanks 2 and the stabilizer 1.

[0028] The discharge section includes a trapezoidal block 231 fixed to the center of the inner cavity of the rear box 23. The trapezoidal block 231 has symmetrically arranged vertical grooves 232 on one side near the rear box 23. A symmetrically arranged slide frame 233 is vertically slidably installed in the two vertical grooves 232. A wedge block 234 that fits into the trapezoidal block 231 is horizontally slidably installed in the slide frame 233. A symmetrically arranged curved rod 235 is installed at the end of each of the two wedge blocks 234 away from the slide frame 233. A mutually symmetrical outer component 236 is installed on each of the two curved rods 235. A spring is installed between the two outer components 236.

[0029] After the animal finishes drinking and leaves the tank 2, the pressure on the filter plate 21 is released. The filter plate 21, no longer under pressure, moves upward under the action of a spring. As the filter plate 21 moves upward, it simultaneously pushes the cleaning plate 220 upward. The cleaning plate 220, in turn, moves the wedge block 234 upward via the curved rod 235. As the wedge block 234 moves upward, it is blocked by the trapezoidal block 231, causing the two trapezoidal blocks 231 to move away from each other. The two trapezoidal blocks 231 move away from each other on the two side slides 233. At this time, the cleaning plates 220 on both sides are on the filter plate 21. The cleaning plates 220 move away from each other, scraping off the grass and impurities that fall onto the filter plate 21 when the animals drink. As the cleaning plates 220 move away from each other, they press against their corresponding barrier plates 224. The barrier plates 224 move upwards after being pressed. As the cleaning plates 220 are about to enter the cleaning box 22, the barrier plates 224, in conjunction with the cleaning plates 220, push the scraped grass and impurities from the filter plate 21 into the cleaning box 22. This upward movement and repositioning of the filter plate 21 completes the cleaning of the grass and impurities on the filter plate 21. The cleaning process keeps the filter plate 21 clean without requiring manual cleaning of the upper part of the filter plate 21. When the animal drinks, pressure is applied to the filter plate 21. Under pressure, the filter plate 21 compresses the spring, causing it to move downwards within the tank 2 until it is submerged. As the filter plate 21 moves downwards, the pushing force on the cleaning plate 220 is released. Without this pushing force, the cleaning plate 220, under the influence of gravity, moves downwards along with the filter plate 21. During this downward movement, the filter plate 21, via the curved rod 235 and the wedge block 234, synchronously drives the slide 233 to slide down within the vertical groove 232. When the two wedge blocks 234... As it moves downward, the pressure exerted by the trapezoidal block 231 on the wedge block 234 gradually decreases. When the contact area between the two wedge blocks 234 and the trapezoidal block 231 gradually decreases, the outer parts 236 on both sides are pulled by the spring. The outer parts 236 on both sides pull the curved rods 235 on both sides to move closer to each other. At this time, the cleaning plates 220 on both sides of the filter plate 21 gradually move closer to each other and are placed in the middle of the filter plate 21. When the animal finishes drinking, the filter plate 21 moves upward and resets. The cleaning plates 220 on both sides move away from each other on the filter plate 21 and automatically scrape the impurities on the filter plate 21 into the cleaning boxes 22 on both sides. The cleaning plate 220 gathers in the middle when the filter plate 21 moves down and spreads out to the sides when it moves up, forming a dynamic cleaning area that can effectively handle impurities that fall onto any part of the filter plate 21 when animals drink water, avoiding the cleaning dead corners that may exist with fixed scrapers. The cooperation between the cleaning plate 220 and the barrier plate 224 is key. It not only scrapes impurities to the edge, but also forms a passage by squeezing the barrier plate 224 upward and then pushing it forward into the cleaning box 22. This action is more proactive and thorough than simple side sweeping, and can effectively prevent light impurities such as grass from scattering or getting stuck at the edge, ensuring a high collection rate of impurities. Since the driving source is the return spring force under the filter plate 21, when there are many impurities on the filter plate 21, part of the energy released by the spring is converted into work to overcome the cleaning resistance. This may form a natural feedback in the machine, ensuring that there is enough force to complete the scraping, but not to damage the mechanism due to excessive force. The entire cleaning process, including scraping, pushing, and collecting, is driven by the natural downward movement of animals drinking water and the upward movement of the mechanical reset spring of filter plate 21. It requires no sensors, controllers, or external power sources (electricity or gas). This passive triggering mechanism is extremely reliable, has a low failure rate, and is suitable for long-term maintenance-free operation in complex environments such as farms. The cleaning action is seamlessly connected with and completed synchronously with the animals' drinking behavior. The cleaning time is "hidden" the moment after the animals leave, without taking up any additional operating time, achieving true "zero-time cost maintenance" in the production process. The clever use of a wedge-trapezoidal mechanism achieves motion conversion. The vertical linear motion of the filter plate 21 is elegantly converted into the horizontal linear motion of the cleaning plate 220 through the engagement of the wedge block 234 and the inclined surface of the trapezoidal block 231. This conversion method is compact and highly efficient. The mechanism cleverly utilizes gravity to automatically reset and converge the cleaning plate 220 as the filter plate 21 descends, and uses spring force to drive the cleaning action as the filter plate 21 ascends. This utilization of natural forces ensures smooth operation and high energy efficiency. The cleaning plate 220 only begins to separate and scrape when the wedge block 234 contacts the trapezoidal block 231 at a specific position on the filter plate 21, and converges before descending to the bottom. This design avoids scraping actions performed in incorrect positions, such as when the filter plate 21 is submerged in water, preventing unnecessary disturbances or mechanical interference.

[0030] A cleaning plate 220 is fixedly installed at the end of the curved rod 235 away from the wedge block 234. The two cleaning plates 220 are set with their opposite sides at an angle. A baffle plate 224 is also provided above the cleaning plate 220. The bottom of the baffle plate 224 is set with an angle. A T-shaped plate 221 with an inverted T shape is provided above the baffle plate 224 and is fixed to the inner cavity of the tank 2. A frame 222 is slidably installed on the outside of the T-shaped plate 221. A spring is installed between the frame 222 and the T-shaped plate 221. A fixing plate 223 is fixedly installed on one side of the bottom of the frame 222. The bottom of the fixing plate 223 is fixedly connected to the baffle plate 224.

[0031] A central component 52 is fixedly installed in the middle of the U-shaped frame 51. The top of the central component 52 has an installation groove. When the activated carbon plate 53 is located in the installation groove, it is installed on the U-shaped frame 51. Drainage holes are also provided on both sides of the activated carbon plate 53.

[0032] The automatic control unit includes take-up and release wheels 42 located on both sides of the blade 41 and fixed to the rotating rod 4. The take-up and release wheel 42 is provided with a guide wheel 43 on the side near the tank 2, which is rotatably connected to the inner wall of the front box 20. A vertical rod 44 is fixedly installed on the side of the guide wheel 43 away from the take-up and release wheel 42. A limiting member 45 is slidably installed on the outside of the vertical rod 44. A spring is sleeved on the outside of the vertical rod 44, and one end of the spring is connected to the limiting member 45.

[0033] A slide bar 46 is fixedly installed on one side of the limiting member 45. A steel rope 47 is installed between the top of the slide bar 46 and the take-up and release wheel 42. The section of the steel rope 47 near the take-up and release wheel 42 is dragged and slid on the guide wheel 43. A connecting plate 48 is fixedly installed at the bottom of the slide bar 46.

[0034] The automatic control unit also includes side grooves 54 symmetrically opened in the inner cavity of the slot box 2. An inner plate 55 is slidably installed in the side groove 54. A spring connected to the top of the inner plate 55 is provided in the side groove 54. A side rod 56 located outside the U-shaped frame 51 is installed between the inner plate 55 and the corresponding connecting plate 48. A positioning member 57 fixed to the side rod 56 is provided between two adjacent U-shaped frames 51. Two inclined plates 58 arranged in a V-shape and hinged to the two adjacent U-shaped frames 51 are rotatably installed on the positioning member 57.

[0035] When the activated carbon plate 53 is to be replaced, the filter plate 21 can be disassembled to open the upper part of multiple U-shaped frames 51, so as to facilitate the replacement of the activated carbon plate 53.

[0036] When water enters the front box 20 and impacts the blade 41, the blade 41 drives the rotating rod 4 to rotate. The rotating rod 4, in turn, drives the take-up and release wheel 42 to rotate. The take-up and release wheel 42, in turn, pulls the sliding rod 46 via the steel cable 47. When the sliding rod 46 moves upward, it causes the limiting member 45 to compress the spring and slide upward on the vertical rod 44. As the sliding rod 46 moves upward, it drives the side rod 56 upward via the connecting plate 48. As the side rod 56 moves upward, it simultaneously drives multiple positioning members 57 to move upward. The positioning members 57, as they move upward... The two inclined plates 58 at the top of the U-shaped frame 51 cause the two adjacent U-shaped frames 51 to slide closer or further apart on the guide rod 5, thereby causing the activated carbon plates 53 in the multiple central components 52 to continuously change position, thus increasing the frequency of contact with the water in the tank 2. When the U-shaped frame 51 moves, it can also drive the external brush frame 59 to scrape the inner wall of the tank 2, preventing scale from adhering to the inner wall of the tank 2. At the same time, the movement of the U-shaped frame 51 can also enhance the flow of water in the tank 2.

[0037] Traditional statically placed activated carbon plates 53 experience rapid saturation of their surface adsorption sites due to localized water flow stagnation, creating "adsorption blind zones." This design forces the activated carbon plates 53 to periodically gather and disperse, constantly changing their position within the water tank 2. This is equivalent to continuous, forced "stirring" of the water, ensuring that all areas of the water have ample opportunity to contact the activated carbon surface. This significantly improves the overall adsorption efficiency and utilization rate of the activated carbon, extending its effective service life. During the reciprocating motion of the activated carbon plates 53, water flows at high speed through the hydrophobic pores on their surface, scouring it. This mechanical action effectively removes larger particles and biofilms that have already adhered to the outer surface of the pores and are about to clog them, keeping the internal micropores of the activated carbon open and maintaining its high adsorption capacity.

[0038] The reciprocating motion of the U-shaped frame 51 itself disturbs the water flow. Combined with the movement of the activated carbon plate 53, it creates beneficial microturbulence in the tank 2. This not only enhances the contact between activated carbon and water, but also promotes the uniform mixing of water in the tank 2, preventing local water quality deterioration.

[0039] The above description is merely an example and illustration of the concept of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the concept of the invention or exceed the scope defined in the claims, they should all fall within the protection scope of the present invention.
