[0002] Water conservancy projects refer to various projects built to control, regulate and utilize natural surface water and groundwater in order to achieve the purpose of eliminating harm and promoting benefits. They include a wide range of application areas and are widely used in projects such as water storage projects, water diversion projects, water lifting projects, water transfer projects, and groundwater source projects. In the construction of embankments, reservoirs, flood storage and diversion areas, culverts and other projects, diversion channels are usually used for diversion in the above-mentioned projects. In the application of diversion channels, cleaning screens are used to intercept solid debris in the fluid, such as branches, leaves, paper, plastic bags, etc. These debris will cause blockage in the diversion channel, thereby affecting the normal operation of the water conservancy project.
[0003] The traditional cleaning grille for diversion channels will have the problem of grid clogging after being used for a period of time. At this time, workers need to dismantle and remove the grille for cleaning or replacement. The removal requires professional workers to operate, which takes a lot of time and workload, and is dangerous, which is not conducive to the personal safety of workers. Moreover, the traditional cleaning grille is a single grille structure. During the period of time when the grille is removed for cleaning, the water flow in the diversion channel cannot be cleaned due to the lack of a cleaning device in the diversion channel. Therefore, the water flow can only be cut off, and the grille must be dismantled, removed, cleaned or replaced, which reduces the cleaning efficiency of the cleaning grille.

[0016] By adopting the above technical solution, the utility model has the following beneficial effects:
[0017] 1. The utility model provides a sewage cleaning grille for water conservancy projects. The sewage cleaning grille is arranged in combination with a lifting mechanism and a sewage blocking assembly. The lifting mechanism enables the front grille plate in the sewage blocking assembly to move up and down. When the front grille plate is lowered, the water flow in the canal is cleaned. When the front grille plate is raised above the operating table, the staff can clean the front grille plate, avoiding the staff from disassembling the grille next to the canal, taking it out for cleaning or replacement, preventing the staff from slipping, improving the safety of the staff, reducing the disassembly steps, solving the problem of inconvenient grille cleaning, and improving work efficiency.
[0018] 2. The utility model provides a sewage cleaning grille for water conservancy projects.

The grille mesh body is sequentially provided with multiple rows of sewage scooping teeth from top to bottom. The sewage scooping teeth have a triangular cross-section along their own length. The sewage scooping teeth are tilted upward at an angle of 20-60 degrees. The triangular cross-section of the sewage scooping teeth along their own length increases the contact area between the sewage scooping teeth and debris in the water, thereby enhancing the sewage cleaning effect of the sewage cleaning grille. The sewage scooping teeth are sequentially provided with multiple rows of sewage scooping teeth from top to bottom. The use of multiple rows of sewage scooping teeth further enhances the sewage cleaning effect of the sewage cleaning grille. The sewage scooping teeth are tilted upward at an angle of 20-60 degrees. With this arrangement, when the front grille plate of the sewage cleaning grille needs to be cleaned, when the lifting mechanism drives the front grille plate to rise, debris on the front grille plate will not fall off, thereby facilitating the cleaning of the sewage on the grille.

[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0032] The present invention will be further explained below in conjunction with specific implementation methods.
[0033] like Figure 1-Figure 3As shown, the present embodiment provides a sewage cleaning screen for water conservancy projects, comprising an operating platform 1, with a first support column 2 and a second support column 3 disposed above the operating platform 1. Preferably, the first support column 2 and the second support column 3 are both located on the centerline of the operating platform 1, with the first support column 2 located on one side of the second support column 3 and a lifting mechanism 4 disposed on the other side of the second support column 3. The bottom of the lifting mechanism 4 is connected to a sewage blocking assembly 5. A front grille plate 8 is disposed horizontally and symmetrically in front of a rear grille plate 7 in the sewage blocking assembly 5. The front grille plate 8 can be moved up and down through a through hole 6 in the operating platform 1 to clean debris. The lifting mechanism 4 allows the front grille plate 8 in the sewage blocking assembly 5 to move up and down. When the front grille plate 8 is lowered, the water in the canal can be cleaned. When the front grille plate 8 is raised above the operating platform 1, the front grille plate 8 can be cleaned. This avoids the need for workers to disassemble the grille for cleaning or replacement near the canal, prevents workers from slipping, improves worker safety, reduces disassembly steps, solves the problem of inconvenient grille cleaning, and improves work efficiency.
[0034] like Figure 5-Figure 7 As shown, in this embodiment, the front grille 8 primarily consists of a grille mesh 11 and mounting plates 10, which are mounted around the grille mesh 11. A scooping mechanism 9 is positioned on the front side of the grille mesh 11, tilted upward at an angle of 20-60 degrees. This arrangement allows the front grille 8 to be cleaned by a lifting mechanism 4, preventing debris from falling off the grille 8 and facilitating cleaning. Multiple rows of scooping mechanisms 9 are arranged from top to bottom throughout the grille mesh 11, enhancing the cleaning efficiency of the cleaning grille. The scooping mechanisms 9 have a triangular cross-section along their length, increasing the contact area between the scooping mechanism 9 and debris in the water, further enhancing the cleaning efficiency of the cleaning grille. The thickness of the front grille 8 varies depending on the tilt angle of the scooping mechanism 9. To ensure smooth passage of the front grille 8 through the through-hole 6, the inner diameter of the through-hole 6 on the operating table 1 must be larger than the scooping mechanism.
[0035] like Figure 1-Figure 3As shown, in this embodiment, the rear grille 7 is composed of a grille mesh 11 and mounting plates 10. The mounting plates 10 are mounted around the grille mesh 11, and the mounting plates 10 on the left and right sides of the grille mesh 11 are fixed to the inner wall of the water channel. To facilitate the flow of water in the water channel, the rear grille 7 and the front grille 8 are installed at least 20 cm apart, and the mesh openings of the grille mesh 11 of the rear grille 7 and the front grille 8 correspond. The rear grille 7 remains fixed in the water channel unless damaged or blocked. The cleaning screen is primarily cleaned through the front grille 8. When cleaning is required, the front grille 8 is raised above the operating table 1 via the lifting mechanism 4. At this time, the rear grille 7 can still temporarily clean the water in the water channel without interrupting the water flow, thereby improving cleaning efficiency. If the rear grille 7 becomes blocked or damaged, staff can be dispatched to remove and clean it.
[0036] like Figures 1-4 As shown, in this embodiment, the lifting mechanism 4 includes a first rotating shaft 12 and a second rotating shaft 13, and the first rotating shaft 12 and the second rotating shaft 13 are respectively arranged at the upper ends of the first support column 2 and the second support column 3, and a guide rail 15 is provided at the lower part of the body of the second support column 3. The guide rail 15 is adapted to the sliding lifting block 16, and the lifting block 16 is fixed on the lifting plate 17. The lifting plate 17 passes through the operating table 1 and is adapted to move, and the lifting plate 17 is integrated with the front grille plate 8; a guide rope 19 is installed on the top of the lifting block 16, and the other end of the guide rope 19 is fixed to the second rotating shaft 13; a rotating handle 18 is provided on one side of the first rotating shaft 12, and the rotating handle 18 drives the first rotating shaft 12. The first rotating shaft 12 is connected to the second rotating shaft 13 through a belt 14 and rotates synchronously.
[0037] The staff rotates the rotary handle 18 to drive the first rotating shaft 12 to rotate. The first rotating shaft 12 drives the second rotating shaft 13 to rotate via the belt 14. When the second rotating shaft 13 rotates, it winds up the guide rope 19, thereby causing the lifting block 16 below the guide rope 19 to move upward along the guide rail 15. The lifting block 16 is fixed to the lifting plate 17, and the lifting plate 17 is integrated with the front grille plate 8, thereby driving the front grille plate 8 to move up and down. The use of the lifting mechanism 4 prevents staff from disassembling the grille next to the canal and then removing it for cleaning or replacement, preventing staff from slipping, improving staff safety, and reducing the number of disassembly steps. Only by turning the rotary handle 18 can the front grille plate 8 be raised above the operating table 1, and then dirt on the front grille plate 8 can be cleaned, thereby facilitating the cleaning of dirt on the grille and improving cleaning efficiency.
[0038] like Figure 3-Figure 4As shown, in this embodiment, the lifting plate 17 is in an inverted T-shape and is fixed to the lifting block 16. The lifting plate 17 is in an inverted T-shape, and the upper portion of the vertical section of the lifting plate 17 is fixedly connected to the lifting block 16 via bolts and an L-shaped plate. The horizontal section of the lifting plate 17 is fixedly connected to the mounting plate 10 on the upper side of the front grille plate 8. The inverted T-shape of the lifting plate 17 increases the fixed mounting area with the front grille plate 8, thereby increasing the stability of the front grille plate 8 when it moves up and down.
[0039] The working principle of the sewage cleaning grille for water conservancy projects of the utility model is as follows:
[0040] First, in the canal that needs to be cleaned, the mounting plates 10 on the left and right sides of the grille net 11 on the rear grille plate 7 are respectively fixed to the inner wall of the canal, and then the operating platform 1 is installed and fixed to the ground on both sides of the canal by pre-embedding. When the amount of dirt accumulated on the front side of the grille plate is small, there is no need to operate the cleaning grille. When cleaning is required, the staff rotates the rotating handle 18 to drive the first rotating shaft 12 to rotate. The first rotating shaft 12 drives the second rotating shaft 13 to rotate through the belt 14. When the second rotating shaft 13 rotates, it will roll up the lead rope 19, so that the lifting block 16 under the lead rope 19 moves upward along the guide rail 15. The lifting block 16 is fixed on the lifting plate 17, and the lifting plate 17 is integrated with the front grille plate 8, so that the front grille plate 8 can be driven to move upward. Then the staff cleans the front grille plate 8. After cleaning, the front grille plate 8 is placed back in the canal by rotating the handle 18.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
