[0028] Currently, the self-cleaning process of trash racks mainly relies on manual operation. Operators regularly inspect and maintain trash racks to ensure their normal function and efficiency. During the manual cleaning process, operators need to use tools such as hooks, shovels or other manual equipment to directly contact the trash racks and carefully remove attached debris, leaves, plastic bags and other accumulations that may clog the grid from the bars.

[0029] However, manual cleaning of trash racks is labor-intensive, inefficient, and has high safety risks, and is difficult to handle when a large amount of trash suddenly accumulates.

[0030] In order to solve this technical problem, the present invention proposes an energy-saving self-cleaning device for a trash rack.

[0031] See also Figures 1 to 3In one embodiment of the present invention, the trash rack 10 includes a waterfront side 11 and a water-receiving side 12 which are arranged opposite to each other. The trash rack energy-saving self-cleaning device includes a cleaning mechanism 100 and a self-cleaning mechanism 200. The cleaning mechanism 100 is arranged at a distance from the trash rack 10. The cleaning mechanism 100 includes a mounting end and a cleaning end. The mounting end is arranged at a distance below the trash rack 10. The cleaning end is slidably arranged against the waterfront side 11 along the extension direction of the trash rack 10. The cleaning end is used to contact and scrape the waterfront side 11 when sliding along the extension direction of the trash rack 10 to clean the trash rack 10. The self-cleaning mechanism 200 is arranged at a distance above the trash rack 10 corresponding to the position of the cleaning mechanism 100. The self-cleaning mechanism 200 is used to clean the cleaning end when the cleaning end moves to the top of the trash rack 10.

[0032] Specifically, the installation end of the cleaning mechanism 100 is arranged below the trash rack 10 at intervals, and the cleaning end can slide along the extension direction of the trash rack 10 and is arranged against the waterfront side 11. In this way, when the cleaning end slides along the trash rack 10, it can contact and scrape the waterfront side 11, thereby realizing automatic cleaning of the trash rack 10, without manual direct contact with the trash rack 10, thereby reducing the labor intensity and safety risks of the operators. At the same time, the self-cleaning mechanism 200 is arranged above the trash rack 10 at intervals, corresponding to the position of the cleaning mechanism 100.

[0033] In order to further improve the cleaning efficiency of the trash rack 10 and ensure the durability of the cleaning mechanism 100, the self-cleaning mechanism 200 is arranged above the trash rack 10 corresponding to the position of the cleaning mechanism 100. When the cleaning end moves to the top of the trash rack 10, the self-cleaning mechanism 200 can clean the cleaning end to avoid the accumulation of dirt on the cleaning end, ensure the cleaning effect, ensure the cleanliness and efficient operation of the cleaning mechanism 100, further reduce the maintenance requirements of the trash rack energy-saving self-cleaning device, and enhance the service life of the trash rack energy-saving self-cleaning device.

[0034] More specifically, the mounting end can be arranged below the trash rack 10 through structures such as rails and slideways to provide reliable support and guidance for the cleaning end. The cleaning end can use structures such as brushes and scrapers to contact and scrape the waterside 11 to remove dirt from the trash rack 10. The cleaning end can be driven by a driving device such as a motor or a hydraulic cylinder to slide back and forth along the extension direction of the trash rack 10 to achieve cleaning and covering of the entire waterside 11. The self-cleaning mechanism 200 can use water spraying, air blowing, etc. to flush or blow away the dirt on the surface of the trash rack 10 when the cleaning end reaches the top of the trash rack 10 to avoid secondary pollution.

[0035] In the technical solution provided by the present invention, the automatic cleaning and self-cleaning functions of the trash rack 10 are realized by arranging the cleaning mechanism 100 and the self-cleaning mechanism 200 at intervals on the trash rack 10. The cleaning mechanism 100 slides along the extension direction of the trash rack 10 without interfering with the structural stability of the trash rack 10, effectively contacts and scrapes the accumulation on the waterfront side 11, thereby improving the cleaning efficiency of the trash rack 10 and reducing the labor intensity and safety risks of the operators. When the cleaning end moves to the top of the trash rack 10, the cleaning mechanism 100 is automatically cleaned by the self-cleaning mechanism 200, which not only maintains the cleaning and efficient operation capabilities of the cleaning mechanism 100, but also reduces the maintenance requirements of the energy-saving self-cleaning device of the trash rack and increases the service life. In addition, the automatic cleaning and self-cleaning method of the trash rack 10 effectively copes with the sudden accumulation of a large amount of dirt, provides an efficient, safe and economical maintenance method for the trash rack 10, not only improves the cleaning efficiency and continuous operation reliability of the trash rack 10, but also reduces the maintenance cost of the trash rack 10 and improves the efficiency of sewage treatment.

[0036] As an optional embodiment, the cleaning end may be, but is not limited to, a metal brush, a rubber knife or a synthetic fiber brush in the related art to adapt to different types of impurities and contamination levels.

[0037] As another optional implementation, an electric heating wire or hot air generator is installed at the cleaning end to heat the cleaning end in a low temperature environment to prevent ice formation and help remove frozen contaminants. A temperature sensor is provided on one side of the cleaning end to automatically adjust the heating intensity according to the ambient temperature to ensure heating efficiency in different temperature environments.

[0038] See also Figure 1 and Figure 2 In an embodiment of the present invention, the cleaning mechanism 100 includes a telescopic driving member 110, a guide rail 120 and a cleaning assembly 130. The guide rail 120 is spaced apart from the trash rack 10, and the extension direction of the guide rail 120 is consistent with that of the trash rack 10. The telescopic driving member 110 is arranged at the bottom end of the guide rail 120, and the cleaning assembly 130 is slidably arranged on the guide rail 120 along the extension direction of the guide rail 120, and the cleaning assembly 130 is arranged on the waterfront side 11; the telescopic driving member 110 forms a mounting end, and the cleaning assembly 130 forms a cleaning end. The telescopic driving member 110 is connected to the cleaning assembly 130 and is used to drive the cleaning assembly 130 to slide along the extension direction of the guide rail 120, so that the cleaning assembly 130 contacts and scrapes the waterfront side 11 when sliding along the guide rail 120 to clean the trash rack 10.

[0039] Specifically, the guide rail 120 is spaced apart from the trash rack 10, and the extension direction is consistent with the trash rack 10, providing a reliable sliding track for the sliding of the cleaning assembly 130. The telescopic driving member 110 is arranged at the bottom end of the guide rail 120 to form a mounting end, providing a driving force for the cleaning assembly 130. The cleaning assembly 130 can be slidably arranged along the guide rail 120, and is arranged against the waterfront side 11 to form a cleaning end. In this way, under the drive of the telescopic driving member 110, the cleaning assembly 130 can slide back and forth along the guide rail 120, and continuously contact and scrape the waterfront side 11 during the sliding process, thereby realizing automatic cleaning of the trash rack 10.

[0040] The cleaning mechanism 100 is spaced apart from the trash rack 10, and its mounting end (i.e., the telescopic driving member 110) is located below the trash rack 10, and the cleaning end (i.e., the cleaning assembly 130) can slide along the extension direction of the trash rack 10. The setting of the guide rail 120 not only provides a track for the sliding of the cleaning assembly 130, but also allows the cleaning assembly 130 to be closer to the waterfront side 11, thereby improving the cleaning effect. At the same time, the connection between the telescopic driving member 110 and the cleaning assembly 130 allows the driving force to be stably and reliably transmitted to the cleaning assembly 130, thereby ensuring the continuity and stability of the cleaning process.

[0041] More specifically, the telescopic drive member 110 may be a hydraulic cylinder, a gas cylinder, an electric push rod, etc., and the cleaning assembly 130 may be driven to slide by telescopic motion. The guide rail 120 may be a steel section, a channel steel, etc., and its cross section may be rectangular, circular, T-shaped, etc., adapted to the connection structure of the cleaning assembly 130. The cleaning assembly 130 may be a brush plate, a scraper, a roller, etc., which contacts and scrapes the waterfront side 11 to remove dirt from the trash rack 10. The cleaning assembly 130 and the guide rail 120 may be matched through a slider, a roller, etc. to achieve smooth sliding.

[0042] Please continue reading Figure 1 and Figure 2 In the embodiment of the present invention, there are two guide rails 120, and the two guide rails 120 are arranged at intervals along the width direction of the trash rack 10, and the trash rack 10 is arranged between the two trash racks 10; the cleaning component 130 includes a brush 131 and an ear plate 132, the brush 131 forms a cleaning end, the brush 131 extends along the width direction of the trash rack 10, and the two ends of the brush 131 along the extension direction are respectively slidably connected to the two guide rails 120 through the ear plates 132, and the telescopic drive member 110 is connected to the ear plate 132.

[0043] Specifically, the two guide rails 120 provide necessary support and guidance for the movement of the cleaning assembly 130. By arranging the guide rails 120 on both sides of the trash rack 10, it can be ensured that the cleaning assembly 130 can stably slide along the guide rails 120 during operation, reducing unnecessary shaking or obstruction, thereby improving the cleaning efficiency. The sliding connection between the ear plate 132 and the guide rail 120 enables the brush 131 to flexibly adjust its position during the cleaning process to adapt to different dirt conditions and cleaning requirements. The brush 131 extending along the width direction of the trash rack 10 can cover a larger area of ​​the trash rack 10, thereby improving the cleaning effect of the trash rack 10. When the telescopic drive member 110 drives the ear plate 132 to move, the cleaning assembly 130 can slide smoothly on the guide rail 120, which is convenient for cleaning the dirt accumulated on the trash rack 10, thereby improving the cleaning efficiency of the cleaning assembly 130 on the trash rack 10.

[0044] Please continue reading Figure 1 and Figure 3 In an embodiment of the present invention, the self-cleaning mechanism 200 includes a rotary drive member 210, a rotating shaft 220, a support 230, a filter plate 240 and a roller brush 250. The filter plate 240 is arranged above the trash rack 10 at intervals corresponding to the position of the waterfront side 11. The filter plate 240 extends along the width direction of the trash rack 10. The filter plate 240 is respectively provided with a rotary drive member 210 and a support 230 at both ends of the filter plate 240 along its extension direction. One end of the rotating shaft 220 is detachably connected to the support 230, and the other end of the rotating shaft 220 is connected to the rotary drive member 210. The roller brush 250 is detachably sleeved on the rotating shaft 220. The rotary drive member 210 is used to drive the rotating shaft 220 to drive the roller brush 250 to rotate. The roller brush 250 is used to clean the cleaning end when the cleaning end moves to the top of the trash rack 10.

[0045] Specifically, one end of the rotating shaft 220 is detachably connected to the support 230, ensuring the convenience of replacement and maintenance of the rotating shaft 220. At the same time, the other end of the rotating shaft 220 is connected to the rotating driving member 210, and the power source input of the rotating driving member 210 can be implemented in a variety of driving modes, such as electric or pneumatic, so as to provide power output for the rotating shaft 220 to drive the roller brush 250 to rotate around the rotating shaft 220, so as to clean the cleaning end when the cleaning end moves to the top of the trash rack 10. The roller brush 250 is detachably sleeved on the rotating shaft 220, which simplifies the daily maintenance work of the roller brush 250 and improves the convenience of operation for operators.

[0046] Please continue reading Figure 1 In an embodiment of the present invention, a plurality of filter holes 241 are provided on the filter plate 240, the filter plate 240 is obliquely arranged above the trash rack 10, the bottom end of the filter plate 240 is connected to the top end of the trash rack 10, the top end of the filter plate 240 is arranged on the side of the backwater side 12 away from the frontwater side 11, and the top end of the filter plate 240 is arranged above the trash rack 10.

[0047] Specifically, the bottom end of the filter plate 240 is connected to the top end of the trash rack 10, so that the filter plate 240 forms an effective filtering interface at the junction with the trash rack 10. Due to the presence of the filter holes 241, when the water flows through the filter plate 240, impurities and particulate matter in the water can be intercepted through these filter holes 241, thereby achieving preliminary filtration of the water flow and ensuring the water quality of the downstream water body.

[0048] The top of the filter plate 240 is arranged on the back side 12, that is, the side away from the front side 11. Since the water flow mainly flows in from the front side 11, the inclined arrangement of the filter plate 240 enables the incoming water to naturally flow to the trash rack 10 by gravity and the kinetic energy of the water flow when passing through the filter plate 240, and is not easy to be retained on the filter plate 240, thereby preventing possible blockage. In addition, the inclined filter plate 240 can further increase the flow speed of the water flow, reduce the risk of water retention, and thus improve the efficiency of the entire self-cleaning process.

[0049] Please continue reading Figure 1 In an embodiment of the present invention, the filter plate 240 is in an arc-shaped structure, and the filter plate 240 is arched upward from the water-facing side 11 toward a direction away from the water-receiving side 12 .

[0050] Specifically, the filter plate 240 with an arc structure is arched from the water-facing side 11 to the direction away from the water-receiving side 12. When the filter plate 240 receives sewage and dirt falling from the self-cleaning mechanism 200 from above, the water flow distribution is more uniform, which can effectively reduce the water accumulation phenomenon on the surface of the filter plate 240 and improve the water flow efficiency.

[0051] In addition, the arc-shaped structure can also enhance the compressive strength of the filter plate 240 and reduce deformation that may be caused by water flow impact, so that the filter plate 240 can maintain a stable shape and effective filtering performance under the continuous water flow, thereby improving the durability and service life of the trash rack energy-saving self-cleaning device.

[0052] More specifically, the arc-shaped filter plate 240 can effectively guide water to flow on its surface. When the water flows through the filter plate 240, it can flow downward along the surface of the filter plate 240 under the action of gravity, effectively reducing the retention of water flow, thereby preventing the blockage of dirt. It is particularly suitable for environments that process a large amount of sewage or solid matter, and improves the filtering effect and efficiency by increasing the passing rate of water flow.

[0053] Please continue reading Figures 1 to 3 , and see Figures 4 to 6In the embodiment of the present invention, the trash rack 10 is obliquely arranged in the sewage treatment chamber 300, and a sewage treatment space 301 is arranged in the sewage treatment chamber 300. A partition wall 400 is arranged at the bottom of the sewage treatment chamber 300, and the partition wall 400 divides the sewage treatment space 301 into a sewage discharge chamber 302 and a drainage chamber 303. A trash-blocking gap 304 is provided between the top of the partition wall 400 and the top of the sewage treatment chamber 300, and the sewage discharge chamber 302 and the drainage chamber 303 are connected through the trash-blocking gap 304; a self-cleaning port 305 is opened at the top of the sewage treatment chamber 300, and the self-cleaning port 305 is arranged on the back water side 12; the bottom end of the trash rack 10 is connected to the top of the partition wall 400, and the top of the trash rack 10 is connected to the top of the sewage treatment chamber 300 corresponding to the position of the self-cleaning port 305; the self-cleaning mechanism 200 is arranged at the self-cleaning port 305, and the cleaning mechanism 100 is arranged on one side of the partition wall 400.

[0054] Specifically, the inclined setting of the trash rack 10 optimizes the functional layout of the sewage treatment chamber 300, facilitating the water flow to flow along the surface of the trash rack 10, thereby effectively intercepting and collecting suspended matter and impurities in the water flow. A sewage treatment space 301 is provided inside the sewage treatment chamber 300 to meet the sewage treatment needs.

[0055] The partition wall 400 is arranged at the bottom of the sewage treatment chamber 300, and the partition wall 400 divides the sewage treatment space 301 into a sewage discharge chamber 302 and a drainage chamber 303. The sewage discharge chamber 302 can effectively collect the sludge and solid particles settled in the sewage, while the drainage chamber 303 provides a direct discharge channel for the treated clean water. At this time, a dirt-blocking gap 304 is arranged between the top of the partition wall 400 and the top of the sewage treatment chamber 300, ensuring that the sewage discharge chamber 302 and the drainage chamber 303 can be fluidly connected through the gap to maintain the overall fluidity of the sewage.

[0056] At the same time, the self-cleaning opening 305 opened at the top of the sewage treatment chamber 300 is arranged on the backwater side 12, providing an opening for convenient operation for the subsequent self-cleaning process. The self-cleaning opening 305 corresponds to the top of the trash rack 10, ensuring that mud and other debris can be properly handled during the cleaning process without hindering the normal liquid flow and sewage treatment process. The bottom end of the trash rack 10 is connected to the top of the partition wall 400 to form an effective connection point, which enhances the stability and effectiveness of the trash rack 10 when working.

[0057] The self-cleaning mechanism 200 is disposed in the self-cleaning opening 305. When dirt is accumulated in the self-cleaning mechanism 200, the self-cleaning mechanism 200 can be cleaned or repaired directly through the self-cleaning opening 305. The self-cleaning mechanism 200 can achieve a continuous cleaning function during the sewage treatment operation by cooperating with the cleaning mechanism 100, thereby preventing dirt accumulation from affecting the working efficiency of the trash rack 10.

[0058] Please continue reading Figure 4 In an embodiment of the present invention, a sewage outlet 306 is provided on the side wall of the sewage treatment chamber 300, and the sewage outlet 306 is connected to the sewage discharge cavity 302. The sewage outlet 306 is arranged near the bottom of the sewage treatment chamber 300, and the cleaning mechanism 100 is arranged in the sewage discharge cavity 302 and near the sewage outlet 306.

[0059] Specifically, a sewage outlet 306 is provided on the side wall of the sewage treatment chamber 300, and the sewage outlet 306 is connected to the sewage discharge chamber 302, and the sewage outlet 306 is arranged near the bottom of the sewage treatment chamber 300. This ensures that the sludge and sediment generated during the sewage treatment process can be effectively discharged, and avoids the reduction of the sewage treatment effect due to sedimentation. By arranging the sewage outlet 306 at the bottom, it is ensured that the sewage can flow directly to the sewage discharge chamber 302 under the action of natural gravity, and the sewage can slide directly into the sewage discharge chamber 302 under the action of natural gravity along the slope of the water-facing side 11, thereby improving the efficiency of sewage discharge.

[0060] The cleaning mechanism 100 is disposed in the sewage chamber 302 and is close to the sewage outlet 306 , so that the cleaning mechanism 100 can be easily maintained.

[0061] Please continue reading Figures 4 to 6 In an embodiment of the present invention, a water inlet pipe 500 is provided at the top of the sewage treatment chamber 300. The water inlet pipe 500 extends vertically. The water inlet pipe 500 is communicated with the trash-blocking gap 304. The water inlet pipe 500 is arranged above the trash rack 10 at a position interval corresponding to the upstream side 11, and the water inlet pipe 500 is arranged between the partition wall 400 and the self-cleaning port 305.

[0062] Specifically, the water inlet pipe 500 extends vertically, and can effectively guide the sewage to be evenly distributed from the top of the treatment chamber to the water-facing side 11 of the inclined trash rack 10. Due to the communication between the water inlet pipe 500 and the trash rack gap 304, when the sewage enters the sewage treatment chamber 300, it will first pass through the trash rack 10 for preliminary solid matter interception. By arranging the water inlet pipe 500 above the trash rack 10, it can be ensured that the sewage flows to the trash rack gap 304 after a certain drop, further promoting gravity sedimentation and separation of solid particles, thereby improving the interception efficiency of clean pollutants and ensuring that the water quality entering the subsequent treatment stage is purer.

[0063] In addition, the water inlet pipe 500 located between the partition wall 400 and the self-cleaning port 305 can effectively prevent sediment accumulation caused by sewage treatment, while the presence of the partition wall 400 helps to maintain the structural separation of the sewage treatment chamber 300 and provides a connection basis for the trash rack 10.

[0064] Please continue reading Figures 4 to 6In an embodiment of the present invention, a battery 600 and a solar photovoltaic panel 700 are arranged on the top of the sewage treatment chamber 300, and the cleaning mechanism 100, the self-cleaning mechanism 200 and the battery 600 are all electrically connected to the solar photovoltaic panel 700.

[0065] It should be noted that the solar photovoltaic panel 700 and the battery 600 are both existing technologies.

[0066] Specifically, the configuration of the solar photovoltaic panel 700 provides a continuous and reliable power supply for the cleaning mechanism 100 and the self-cleaning mechanism 200. The photovoltaic panel can convert light energy into electrical energy through the conversion of solar energy, which is then used for the operation of the entire trash rack energy-saving self-cleaning device.

[0067] The battery 600 is used to store the excess electricity generated by the solar photovoltaic panel 700. It ensures that the trash rack energy-saving self-cleaning device can still operate normally under insufficient sunlight or unfavorable weather conditions. As an energy storage medium, the battery 600 provides stability and continuous support for the system. By arranging the solar photovoltaic panel 700 and the battery 600 on the top of the sewage treatment chamber 300, not only is the sewage treatment process self-sufficient in electricity, but the environmental protection performance of the trash rack energy-saving self-cleaning device is also improved.

[0068] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
