Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a net cleaning device. Background Technology

[0002] In marine ecological protection and fishery resource maintenance, underwater interception nets serve as crucial facilities, making regular cleaning and maintenance essential. Traditional cleaning methods primarily employ high-pressure water rinsing, which has significant limitations: firstly, simple water rinsing is insufficient to effectively remove stubborn stains and biological deposits adhering to the nets; secondly, the wastewater and grime generated during cleaning cannot be effectively collected and treated, easily causing secondary pollution. Furthermore, existing cleaning equipment often only provides a simple rinse to the surface of the nets, failing to achieve deep cleaning, particularly in removing dirt from inside the mesh. Simultaneously, the cleaning equipment itself is prone to accumulating dirt, affecting cleaning effectiveness over long-term use. These problems result in unsatisfactory cleaning results for the interception nets, often necessitating frequent replacements and increasing operating costs. Summary of the Invention

[0003] This invention provides a net cleaning device. By rotating the first and second dials together inside the cleaning drum, and combining them with brush bristles and water outlets, the cleaning effect on the net and the inner wall of the cleaning drum is improved, thus solving the problems of insufficient cleaning caused by simply rinsing the net and the accumulation of dirt in the cleaning device itself.

[0004] This application provides a net cleaning device, including a cleaning cylinder, a first dial wheel, a second dial wheel, and a drive device; the first dial wheel extends axially through the cleaning cylinder and to the outside of the cleaning cylinder, and is suspended in the internal space of the cleaning cylinder; the second dial wheel is installed axially inside the cleaning cylinder and contacts the cylindrical inner wall of the cleaning cylinder; the drive device is installed on the axially outer side of the cleaning cylinder and is connected to the first dial wheel through its drive shaft; wherein, the first dial wheel and the second dial wheel are connected so that when the first dial wheel rotates inside the cleaning cylinder, the second dial wheel revolves around the first dial wheel along the inner wall of the cleaning cylinder.

[0005] In one embodiment of the present invention, bristles are provided on the outer walls of the first and second dials, the bristles are arranged along the axial direction of the first and second dials and are spaced apart in the circumferential direction of the first and second dials.

[0009] In one embodiment of the present invention, the cooperating mechanism includes a cooperating wheel and a cooperating bracket.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0022] In existing technologies, underwater interception nets, when immersed in the marine environment for extended periods, easily accumulate large amounts of biological fouling and sediment. Traditional cleaning methods primarily rely on high-pressure water jets, but the force of the water flow is insufficient to thoroughly remove tightly adhered contaminants. Fixed cleaning devices often have blind spots and cannot adapt to interception nets of different sizes and shapes; furthermore, the wastewater generated during the cleaning process is difficult to collect and treat effectively.

[0023] Please see Figures 1 to 3 , Figure 1A cleaning device comprising a cleaning cylinder 10, a first dial wheel 30, a second dial wheel 31, and a drive device 20 is provided according to an embodiment of the present invention. The first dial wheel 30 extends axially through the cleaning cylinder 10 and extends to the outside of the cleaning cylinder 10, and is suspended in the internal space of the cleaning cylinder 10. The second dial wheel 31 is installed axially inside the cleaning cylinder 10 and contacts the cylindrical inner wall of the cleaning cylinder 10. The drive device 20 is installed on the axially outer side of the cleaning cylinder 10 and is connected to the first dial wheel 30 through its drive shaft. The first dial wheel 30 and the second dial wheel 31 are connected so that when the first dial wheel 30 rotates inside the cleaning cylinder 10, the second dial wheel 31 revolves around the first dial wheel 30 along the inner wall of the cleaning cylinder 10.

[0024] In this embodiment of the invention, the cleaning cylinder 10 refers to a cylindrical container that holds the intercepting net. It can be made of stainless steel and welded together, with removable end caps at both ends for easy maintenance. The first dial wheel 30 refers to a rotating component that axially penetrates the cleaning cylinder 10. Its bearing seat can be fixed to the end plate of the cylinder, and the wheel diameter can be 10%-40% of the inner diameter of the cylinder. The second dial wheel 31 refers to a rotating component that circumferentially contacts the inner wall of the cylinder. Its rim can be provided with a wear-resistant rubber layer, and its diameter maintains a gap of 1-5mm with the inner diameter of the cylinder. The drive device 20 refers to a power output mechanism, which can be a geared motor connected to the first dial wheel 30 with a coupling. The connection between the first dial wheel 30 and the second dial wheel 31 means that they are rigidly connected, so that when the first dial wheel 30 rotates, it drives the second dial wheel 31 to revolve around it.

[0025] Specifically, after the drive unit 20 is started, it drives the first dial wheel 30 to rotate around its own axis, and through a rigid connection, pulls the second dial wheel 31 to move in a circular motion along the inner wall of the cleaning cylinder 10. The first dial wheel 30 is suspended in the air to form the central cleaning area, while the second dial wheel 31 is close to the cylinder wall to form the edge cleaning area. When the interception net is placed into the cleaning cylinder 10, the two dial wheels rotating in different areas drive the net surface to move in multiple directions, removing the attached substances on the net surface through various vibrations. The rigid connection structure maintains a relatively constant rotation between the two dial wheels, ensuring the coordination of the cleaning action.

[0026] Compared to traditional cleaning equipment that often employs a single-shaft agitation structure, resulting in limited contact area between the cleaning components and the screen, this embodiment utilizes a dual-wheel synergy to create a three-dimensional cleaning space. The main cleaning wheel handles deep cleaning of the main area, while the auxiliary cleaning wheel simultaneously cleans the cylinder walls and edges. The connection structure ensures relative motion between the two cleaning wheels and allows for multi-directional friction between the brush bristles 32 on the two rotating wheels and the screen surface. This friction, combined with the centrifugal force generated by rotation, enhances the removal of contaminants from the screen surface.

[0027] Thus, this embodiment of the application achieves bidirectional brushing and cleaning of the intercepting net, solving the problem of incomplete decontamination in traditional water pressure rinsing methods. The three-dimensional cleaning space formed by the rotating dial can adapt to the cleaning needs of intercepting nets of different sizes, and the transmission mechanism ensures coordinated and stable cleaning actions. The sealed cleaning cylinder 10 effectively collects and treats cleaning wastewater, avoiding secondary pollution.

[0028] Please see Figure 2 and Figure 3 In one embodiment, bristles 32 are provided on the outer walls of the first dial 30 and the second dial 31. The bristles 32 are arranged along the axial direction of the first dial 30 and the second dial 31 and are spaced apart in the circumferential direction of the first dial 30 and the second dial 31.

[0029] In this embodiment of the invention, the axial arrangement of the bristles 32 means that the bristles 32 extend and are arranged along the axis of the dial wheel. Specifically, this can be achieved by using multiple rows of bristle groups 32 parallel to the axis, with each row of bristle groups 32 spaced apart circumferentially. The circumferential arrangement of the bristles 32 means that gaps are formed between adjacent bristle groups 32. Specifically, this can be achieved by arranging them at equal angles, for example, by setting a row of bristles 32 at 60-degree or 90-degree intervals.

[0030] Specifically, the bristles 32 extend axially to cover the longitudinal area of ​​the outer wall of the deflector wheel, and are arranged at circumferential intervals so that the bristles 32 form periodic contact with the surface of the intercepting net during rotation. When the first deflector wheel 30 and the second deflector wheel 31 rotate, the axially arranged bristles 32 continuously brush along the surface of the intercepting net, and the circumferentially spaced arrangement prevents too many bristles 32 from tangling or obstructing the net surface during rotation. At the same time, the gaps between adjacent bristle groups 32 allow water flow to pass through, reducing the resistance when the bristles 32 contact the intercepting net, and the water flow washes away the detached dirt.

[0031] Compared to traditional net cleaning equipment where the bristles 32 are typically randomly distributed or arranged in a single direction, leading to uneven cleaning coverage or insufficient cleaning power in certain areas, this application achieves a stable cleaning trajectory for the bristles 32 during rotation through a regular arrangement in both the axial and circumferential directions. This not only expands the contact area with the net but also avoids water flow obstruction caused by excessively high bristle density.

[0032] Thus, the embodiments of this application achieve uniform removal of dirt from the surface of the interception net. The axially arranged bristles 32 cover the longitudinal area of ​​the interception net, and the circumferentially spaced arrangement ensures smooth water flow and reduces wear on the bristles 32. The combination of the two improves the cleaning efficiency of the mesh structure and fiber surface.

[0033] Please see Figure 2 and Figure 3In one embodiment, the bristles 32 are evenly distributed in the axial and circumferential directions of the first dial 30 and the second dial 31. The diameter of the first dial 30 is larger than the diameter of the second dial 31, and the length of the bristles 32 on the first dial 30 is greater than the length of the bristles 32 on the second dial 31.

[0034] In this embodiment of the invention, axial uniform arrangement means that the bristles 32 are arranged at equal intervals along the axial direction of the first dial wheel 30 and the second dial wheel 31. Specifically, this can be achieved by providing equidistant annular grooves or mounting holes on the outer wall of the dial wheel to ensure that the bristles 32 cover the entire axial area. Circumferential uniform arrangement means that the bristles 32 are distributed at equal angular intervals along the circumference of the dial wheel. Specifically, this can be achieved by providing mounting holes at equally spaced angles on the outer wall of the dial wheel, so that the bristles 32 form a continuous and gapless coverage area when rotating.

[0035] Specifically, the outer walls of the first and second gear wheels 30 and 31 are respectively provided with multiple sets of bristles 32. Each set of bristles 32 extends axially, and adjacent sets of bristles 32 are spaced at a fixed angle in the circumferential direction. When the drive device 20 drives the first gear wheel 30 to rotate, the evenly distributed bristles 32 form continuous contact with the surface of the intercepting net during rotation. The axial uniform distribution ensures that the bristles 32 fully cover the intercepting net along its length, and the circumferential uniform distribution allows the bristles 32 to repeatedly brush the intercepting net at a fixed frequency within the rotation cycle. In conjunction with this, the water outlet holes 33 between the bristles 32 are evenly distributed axially and circumferentially, allowing the high-pressure water flow to evenly cover the surface of the intercepting net, avoiding localized cleaning dead zones caused by uneven distribution of the bristles 32.

[0036] Furthermore, the first deflector 30 is located in the axial center of the cleaning cylinder 10. Compared to the second deflector 31 located on the cylinder wall, it has a larger diameter and longer bristles 32. On the one hand, it is easier to bear the interaction forces during the cleaning process of the intercepting net in the cleaning cylinder 10. On the other hand, the first deflector 30 itself and the longer bristles 32 provide a sufficiently large partition structure in the internal space of the cleaning cylinder 10 to control the posture of the intercepting net placed in the cleaning cylinder. The intercepting net placed in the cleaning cylinder 10 is initially located above the first deflector 30. Under the action of gravity, it interacts with the rotation of the first deflector 30 and its bristles 32 to achieve initial cleaning. After falling into the space below the first deflector 30, the first deflector 30 in the middle of the cleaning cylinder 10 and the second deflector 31 moving along the cylinder wall clean its two sides to maintain the cleanliness of the intercepting net.

[0037] Compared to traditional net cleaning equipment where the bristles 32 are typically arranged in a non-uniform, dense pattern, making it difficult for them to penetrate the mesh of the net during cleaning and resulting in blind spots, this embodiment uses a dual uniform arrangement design in both the axial and circumferential directions. This allows the bristles 32 ample space during rotation to achieve full coverage of the net surface, solving the problem of incomplete cleaning caused by the dense or uneven distribution of bristles 32 in traditional equipment.

[0038] Thus, the embodiments of this application enable the bristles 32 to make uniform contact with the surface of the interception net during rotation, and with the uniformly distributed high-pressure water jet, the removal efficiency of stains on the surface of the interception net is significantly improved, avoiding fluctuations in cleaning effect caused by excessively large or small gaps between the bristles 32, and ensuring that all areas of the interception net can receive consistent cleaning treatment.

[0039] Please see Figure 2 and Figure 3 In one embodiment, a cooperating mechanism 40 is installed between the first dial 30 and the second dial 31, and the second dial 31 rotates around the first dial 30 through the connected cooperating mechanism 40.

[0040] In this embodiment of the invention, the coordinating mechanism 40 refers to a mechanical component used to transmit power and control the motion trajectory. Specifically, it can adopt a rigid connection structure such as a wheel, which is used to pull the second wheel 31 to revolve around it by the rotation of the first wheel 30. Alternatively, it can adopt a flexible connection structure such as a support component with elastic deformation capability, which can be made of rubber or spring steel material. Its elastic deformation direction is along the axial direction between the first wheel 30 and the second wheel 31, and its function is to buffer the motion impact and maintain the relative position between the second wheel 31 and the cylinder wall.

[0041] Specifically, the cooperating mechanism 40, through a combination of a rigid cooperating wheel and an elastic cooperating bracket, transmits the rotational power of the first dial wheel 30 to the second dial wheel 31. When the drive device 20 drives the first dial wheel 30 to rotate, the cooperating wheel and the cooperating bracket are linked, causing the second dial wheel 31 to maintain contact with the inner wall of the cleaning drum 10 while revolving around the first dial wheel 30. The elastic cooperating bracket deforms during the movement, adapting to the dynamic changes in the internal space of the cleaning drum 10, ensuring that the second dial wheel 31 always remains in close contact with the drum wall.

[0042] Compared to traditional cleaning devices where auxiliary cleaning components typically employ fixed structures or independent drives, making coordinated movement of the primary and secondary components impossible, this embodiment establishes a linkage between the two gear wheels through a coordinating mechanism 40. This enables the second gear wheel 31 to revolve under a single drive source, simplifying the equipment structure and enhancing motion synchronization.

[0043] Thus, this embodiment of the application achieves continuous contact cleaning of the inner wall of the cleaning cylinder 10, while expanding the cleaning coverage area through a composite motion trajectory. The elastic support characteristics of the cooperating mechanism 40 can automatically compensate for mechanical assembly errors, ensuring that the two dials are always in an effective working position during the cleaning process, avoiding a decrease in cleaning efficiency due to vibration or wear.

[0044] In one embodiment, the second dial 31 is rotatably connected to the cooperating mechanism 40.

[0045] In this embodiment of the invention, the rotatable connection refers to the power transmission between the second dial wheel 31 and the cooperating mechanism 40 through a rotatable mechanical structure. Specifically, it can be achieved by rotatable installation, so that the second dial wheel 31 can both revolve around the first dial wheel 30 and rotate around its own axis under the drive of the cooperating mechanism 40. This allows the second dial wheel 31 and its bristles 32 to roll along the cylinder wall and rotate relative to the intercepting net, just like the first dial wheel 30. This gives the first dial wheel 30 and the second dial wheel 31, which are in contact on both sides of the intercepting net, similar cleaning functions.

[0046] Specifically, the second dial wheel 31 is mounted at the end of the cooperating mechanism 40 via a rotatable connection. When the first dial wheel 30 rotates under the drive of the drive device 20, the cooperating mechanism 40 transmits rotational power to the second dial wheel 31, causing it to rotate on its own axis while revolving around the first dial wheel 30. This composite motion mode allows the bristles 32 on the second dial wheel 31 to move circumferentially along the inner wall of the cleaning cylinder 10, and also to apply multi-directional brushing action to the contact area through its own rotation. The rotatable connection structure allows the second dial wheel 31 to adaptively adjust the contact angle according to the shape of the inner wall of the cleaning cylinder 10 or the position of the intercepting net during movement, avoiding motion interference caused by rigid connections.

[0047] Compared to traditional cleaning equipment where auxiliary cleaning components typically only achieve translational or rotational movement in a single direction, this embodiment utilizes a rotating connection to enable the second deflector 31 to simultaneously revolve and rotate, forming a dynamic brushing path. This significantly increases the coverage area and frequency of contact between the bristles 32 and the intercepting net. Furthermore, the rotating connection structure avoids cleaning blind spots caused by positional deviations in traditional fixed auxiliary cleaning components.

[0048] Thus, this embodiment of the application achieves stability in the compound motion of the second deflector 31 during the cleaning process, enabling the dirt on the surface of the intercepting net and the inner wall of the cleaning cylinder 10 to be brushed and removed from multiple angles. The rotating connection structure ensures that the second deflector 31 can autonomously adjust its rotation state during revolution, adapting to the cleaning needs of intercepting nets of different shapes, while reducing wear on the mechanical structure. The rotation of the second deflector 31 also enhances the coverage of the water jet from the water outlet 33, creating a rotating flushing effect.

[0049] Please see Figure 2 and Figure 3 In one embodiment, the cooperating mechanism 40 includes a cooperating wheel and a cooperating bracket. The cooperating wheel is a rigid structure, and the cooperating bracket is an elastic structure. The elastic deformation direction of the cooperating bracket is the direction of the line connecting the first gear wheel 30 and the second gear wheel 31. The first gear wheel 30 and the second gear wheel 31 are connected by a cooperating wheel or a cooperating bracket.

[0050] In this embodiment of the invention, the cooperating wheel refers to a rigid connecting component used to transmit power, forming a hard connection between them. Specifically, it can be implemented using a wheel disc structure. Its function is to ensure the stability of power transmission between the first dial wheel 30 and the second dial wheel 31. The cooperating bracket refers to a flexible connecting component with elastic deformation capability. Specifically, it can be implemented using spring steel plates or rubber-based composite materials. Its function is to adjust the relative position between the first dial wheel 30 and the second dial wheel 31 through elastic deformation to adapt to changes in the size of the inner wall of the cleaning cylinder 10 or the placement of the intercepting net. The design that the elastic deformation direction is along the line connecting the two dial wheels ensures that the cooperating bracket only extends and contracts in this direction when under force, avoiding interference from displacement in other directions. Figure 2 and Figure 3 The diagram shown is a schematic of a co-drive wheel with a rigid structure.

[0051] Specifically, when the drive device 20 drives the first dial wheel 30 to rotate, it drives the second dial wheel 31 to revolve around the first dial wheel 30 via a co-drive wheel or co-drive bracket. When a co-drive wheel is used, the second dial wheel 31 maintains a constant contact pressure with the inner wall of the cleaning cylinder 10 under rigid constraint. When a co-drive bracket is used, the elastic deformation allows the second dial wheel 31 to make radial minor adjustments during its revolution, compensating for manufacturing errors in the inner wall of the cleaning cylinder 10 or spatial changes caused by the deformation of the intercepting net. For example, when the intercepting net is against the cylinder wall, the elastic deformation of the co-drive bracket can absorb the spatial dimension changes caused by the intercepting net, preventing the second dial wheel 31 from having a hard collision with the intercepting net, and as the second dial wheel 31 continues to run, it pulls the intercepting net away from the contact state with the cylinder wall.

[0052] It should be noted that when using a flexible co-movement support structure, the first deflector 30 can be eccentrically mounted on the axial direction of the cleaning cylinder 10, ensuring that the second deflector 31 remains in contact with the cylinder wall. The eccentrically mounted first deflector 30 divides the interior of the cleaning cylinder 10 into irregularly shaped spatial regions. This allows for the adaptation of different sized interception nets within the cleaning cylinder 10, and also enables control over the orientation and position of the interception net within the cleaning cylinder 10. For example, by eccentrically positioning the first deflector 30 towards the lower part of the cleaning cylinder 10, the interception net is prevented from falling below it. This allows the interception net to rotate under gravity along with the bristles 32 on the first deflector 30, improving the cleaning effect on the interception net.

[0053] Compared to traditional cleaning equipment where the rollers on the cylinder wall are typically fixedly connected, making it impossible to dynamically adjust their contact with the cylinder wall and leading to cleaning dead zones or equipment wear, this embodiment uses a combination of rigid co-drive wheels and flexible co-drive supports. This ensures efficient power transmission while achieving adaptive adjustment of contact pressure, making it particularly suitable for cleaning different sizes of interceptor nets.

[0054] Thus, this application solves the problem of unstable contact between the auxiliary dial wheel and the cylinder wall, ensuring that the second dial wheel 31 always effectively contacts the inner wall of the cleaning cylinder 10 during its revolution. At the same time, the flexible selection of two connection methods takes into account both the stability of equipment operation and the adaptability to working conditions, significantly improving the uniformity of the interception net cleaning and the service life of the equipment.

[0055] Please see Figure 2 and Figure 3 In one embodiment, the first dial 30 and the second dial 31 are hollow structures. The end of the first dial 30 away from the drive device 20 is connected to a water inlet pipe. The first dial 30 and the second dial 31 are connected by a coordinating mechanism 40. The first dial 30 and the second dial 31 are also provided with water outlet holes 33, which are opened between the bristles 32.

[0056] In this embodiment of the invention, the hollow structure refers to the cavity formed inside the dial wheel that can accommodate fluid. This can be achieved using metal tubing or injection molding to construct a water flow channel. The cooperating mechanism 40 is connected, meaning a fluid transmission path is formed through rigid or elastic connecting components. For example, the cooperating mechanism 40 can be a shell structure, or a through hole can be provided inside the cooperating wheel, or a water guide pipe can be embedded in the cooperating bracket, allowing water flow to be transmitted from the first dial wheel 30 to the second dial wheel 31. The water outlet 33 is located between the bristles 32, meaning the holes are distributed in the gap area between adjacent bristles 32. This can be achieved using drilling or in-mold molding processes to prevent interference from water flow during the movement of the bristles 32. The water inlet pipe is not shown in the accompanying drawings.

[0057] Specifically, the inlet pipe introduces external water into the hollow cavity of the first deflector wheel 30, and the water flow enters the second deflector wheel 31 through the connecting structure inside the cooperating mechanism 40. When the drive device 20 drives the first deflector wheel 30 to rotate, the water flow is ejected from the water outlet holes 33 of the first deflector wheel 30 and the second deflector wheel 31 under the action of centrifugal force. High-pressure water flow can also be provided to make the water outlet holes 33 eject jets to enhance the scouring effect on the inside of the cleaning cylinder 10 and the intercepting net. The water outlet holes 33 of the first deflector wheel 30 can spray water radially to directly impact the surface of the intercepting net; and with the rotation of the first deflector wheel 30 and the second deflector wheel 31, the sprayed water flow can be made to wash the intercepting net and the cylinder wall at multiple angles. The bristles 32 and the water outlet holes 33 work together, and the mechanical scraping of the bristles 32 combined with the impact cleaning of the water flow can effectively remove stubborn stains in the pores of the intercepting net.

[0058] Compared to traditional cleaning equipment that typically uses single mechanical brushing or fixed-direction water rinsing, which is insufficient for thoroughly cleaning the mesh structure, this embodiment utilizes a combination design of a hollow dial wheel and a cooperating mechanism 40. This allows the two dial wheels to rotate independently while simultaneously transmitting water flow, achieving a combined effect of brushing and multi-angle rinsing. The rotational effect generated by the tangential water outlet 33 of the second dial wheel 31 expands the water flow coverage area, avoiding cleaning blind spots.

[0059] Thus, this embodiment of the application can simultaneously achieve the dual cleaning effect of mechanical brushing and dynamic water rinsing. The rotational motion generated by the tangential water flow enhances the cleaning effect on the inner wall of the cleaning cylinder 10. The water flow transmission path design between the dials ensures that the equipment maintains a stable water supply pressure during rotation, ensuring that the spray intensity of each water outlet 33 is uniform. The alternating arrangement of the bristles 32 and the water outlets 33 not only avoids the water flow being blocked by the bristles 32, but also forms alternating cleaning zones, improving the cleaning efficiency for the complex structure of the interception net.

[0060] In one embodiment, the water outlet 33 on the second dial 31 is arranged tangentially thereon.

[0061] In this embodiment of the invention, the tangential setting means that the central axis of the water outlet 33 is aligned with the circumferential tangential direction of the second dial wheel 31. Specifically, this can be achieved by opening an inclined channel on the outer wall of the second dial wheel 31, with the extension direction of the channel forming an angle with the tangential direction of the second dial wheel 31 during rotation. This design ensures that the water jet direction matches the movement trajectory of the second dial wheel 31, generating a tangential impact force during rotation.

[0062] Specifically, when the second deflector 31 revolves around the first deflector 30, it rotates under the drive of the cooperating mechanism 40. At this time, the direction of the water flow from the tangentially positioned water outlet 33 dynamically matches the rotation direction of the second deflector 31, and the water flow continuously washes the inner wall of the cleaning cylinder 10 and the surface of the intercepting net along the circumferential tangential direction of the second deflector 31. For example, the water outlet 33 can be designed to be inclined at a 15-45 degree angle to the outer wall of the second deflector 31, so that the water flow forms a tangential scouring force when it contacts the intercepting net, stripping off the attached dirt. At the same time, the reaction force generated by the tangential water flow can assist the rotation of the second deflector 31, reducing the energy consumption of the drive device 20. The tangential water flow of the second deflector 31 can also be used to further expand the spray angle of the water jet from the water outlet 33 inside the cleaning cylinder 10, enhancing the cleaning effect on the intercepting net and the cylinder wall.

[0063] Compared to traditional cleaning equipment where the water outlet 33 is typically vertically positioned, resulting in water flow impacting the interceptor mesh at a fixed angle and creating blind spots, the tangential water outlet 33 dynamically adjusts the water jet angle, allowing the water flow coverage to change with the movement trajectory of the second deflector 31. This creates a multi-angle rinsing effect, effectively removing accumulated dirt, especially in complex areas where the cylinder wall meets the interceptor mesh.

[0064] Thus, this application solves the problem of low cleaning efficiency caused by the single water flow impact angle in traditional cleaning equipment. The dynamic flushing water flow generated by the tangential water outlet 33 can cover a larger cleaning area. Combined with the combined motion of the rotation and revolution of the second deflector 31, it enhances the dirt removal effect on the surface of the interception net and the cylinder wall, while reducing water flow resistance and improving the stability of equipment operation.

[0065] Please see Figure 1 and Figure 2 In one embodiment, the upper and lower sides of the cleaning cylinder 10 are provided with a placement port and a removal port for the intercepting net, and a cover plate 11 is provided on the placement port and the removal port.

[0066] In this embodiment of the invention, the placement port refers to the opening structure formed on the top of the cleaning cylinder 10 for inserting or removing the interceptor net. Specifically, it can be a rectangular, circular, or irregularly shaped opening adapted to the shape of the interceptor net. The edge of the opening can be provided with a sealing groove or a positioning buckle. The cover plate 11 refers to the openable and closable structure covering the placement port. Specifically, it can be a hinged flip cover, a sliding cover, or a flat structure with locking bolts. A sealing strip can be provided on the inner side of the cover plate 11.

[0067] Specifically, the netting is vertically inserted into the cleaning cylinder 10 through the top placement opening, and the cover plate 11 closes to form a sealed structure with the placement opening. The placement opening is positioned in the center of the top of the cleaning cylinder 10, allowing the netting to fall naturally under gravity into the cleaning area between the first and second dial wheels 30 and 31. When the cover plate 11 closes, it presses against the top surface of the cleaning cylinder 10 through a rubber sealing ring to prevent water splashing during cleaning. When the netting needs to be removed, the cover plate 11 rotates open along the hinge axis, allowing the operator to remove it directly from the top or bottom, preventing the netting from getting tangled with the dial wheel bristles 32. Simultaneously, in some light cleaning conditions, the netting can be simultaneously inserted and removed through the placement opening at the top of the cleaning cylinder 10, eliminating the need to drain any underutilized cleaning fluid inside the cleaning cylinder 10 and avoiding waste.

[0068] In some specific embodiments, the cover plate 11 can be integrated with a transparent observation window to facilitate real-time monitoring of the cleaning process; a guide slope is provided at the edge of the placement port to prevent cleaning fluid residue; the locking mechanism of the cover plate 11 adopts a magnetic snap or a rotary snap to achieve quick opening and closing.

[0069] Thus, this embodiment of the application achieves rapid positioning and loading of the intercepting net within the cleaning cylinder 10, preventing displacement of the intercepting net due to water flow impact during the cleaning process. At the same time, the top sealing cover 11 effectively isolates water mist from overflowing, maintaining a clean working environment.

[0070] Please see Figure 1 and Figure 3 In one embodiment, the cleaning cylinder 10 is provided with a water injection hole 12 and a drain hole 13 on its upper and lower sides, respectively.

[0071] In this embodiment of the invention, the water injection hole 12 refers to a through hole formed on the upper side of the cleaning cylinder 10 for introducing cleaning water or cleaning agents. Specifically, it can be implemented using a tubular structure with a threaded interface or flange connection, and its function is to provide a continuous flow of water or chemical cleaning medium for the cleaning process. In this embodiment of the invention, the drain hole 13 refers to a through hole formed on the lower side of the cleaning cylinder 10 for discharging wastewater and solid residue. Specifically, it can be implemented using a tubular structure with a filter screen or valve control, and its function is to separate wastewater from the clean area to prevent secondary pollution.

[0072] Specifically, the water injection hole 12 is located on the upper side of the cleaning cylinder 10, facilitating the injection of cleaning water or disinfectant into the cylinder through an external pipeline. The injected liquid is evenly distributed onto the surface of the interception net by the vortex generated by the rotation of the dial. The drain hole 13 is located on the lower side of the cleaning cylinder 10, using gravity to collect and discharge the wastewater and detached dirt after cleaning. For example, a removable filter screen can be installed inside the drain hole 13 to intercept solid impurities and achieve dry and wet separation. During the cleaning process, the water injection hole 12 and the drain hole 13 form a circulation path, ensuring continuous renewal of the cleaning medium and preventing wastewater stagnation from affecting the cleaning effect. Furthermore, placement and removal ports can be provided on the upper and lower sides of the cleaning cylinder 10 to simultaneously perform operations such as cleaning residual dirt and maintaining components inside the cleaning cylinder 10.

[0073] In summary, the interception net cleaning device provided by the present invention drives the second wheel to revolve around it by the rotation of the first wheel, and the combination of brush bristles and water outlet holes forms a multi-dimensional angle cleaning of the interception net in the cleaning cylinder, effectively removing stubborn stains from the surface of the interception net and the inside of the mesh.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
