Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 As shown:

[0023] A cleaning device for trash racks used in water conservancy projects includes a base frame 101.

[0024] In this implementation plan: The existing device {publication (announcement) number}: CN214194399U discloses a cleaning device for trash racks in water conservancy projects. To solve the technical problems existing in this prior art, such as the background art disclosed above, "When the above design is used, although it cleans one side of the trash rack by setting a cleaning brush, the device can only clean one side of the trash rack at a time and cannot clean the other side at the same time. During use, it is necessary to manually flip the trash rack over and clean it again, which reduces work efficiency." In combination with the use, this problem is obviously a real and difficult problem to solve. The electrical equipment involved in this product is all powered by an external power source. The solution also includes an electrical control cabinet, which is set on the base frame 101. During use, each electrical device can be started and operated separately through the electrical control cabinet. The power connection method of each electrical device is an existing mature technology and is well known to those skilled in the art. It will not be described in detail here.

[0025] Furthermore:

[0026] like Figures 1-3 As shown:

[0027] Based on the above: multiple sets of equidistantly arranged first rollers 102 are rotatably mounted on the base frame 101 via a rotating shaft;

[0028] A cleaning mechanism 2 for cleaning both sides of the trash rack is installed on the base frame 101. The cleaning mechanism 2 includes two sets of drive motors 203 and a brush rod 205 fixed to the output end of the drive motors 203.

[0029] The cleaning mechanism 2 also includes a bracket 201 fixed on the base frame 101 and arranged symmetrically, and a mounting base 202 set on the top of the bracket 201. The drive motor 203 is fixed on the upper surface of the mounting base 202, and the output end of the drive motor 203 is rotatably connected to the mounting base 202 through a bearing.

[0030] The base frame 101 is also equipped with a flushing mechanism 3 for flushing both sides of the trash rack. The flushing mechanism 3 includes two sets of U-shaped tubes 304 fixed to the surface of the base frame 101 and multiple sets of nozzles 303 fixed and connected to the surface of the U-shaped tubes 304. A water pump 301 is provided on one side of the base frame 101. A connecting pipe 302 is fixed to the output end of the water pump 301. Both ends of the connecting pipe 302 are fixed and connected to the two sets of U-shaped tubes 304. The two sets of U-shaped tubes 304 are located on both sides of the two sets of brackets 201. The input end of the water pump 301 is connected to the external water supply system.

[0031] A guide mechanism 4 for guiding and moving the trash rack is installed on the base frame 101. The guide mechanism 4 includes support plates 401 arranged symmetrically on both sides of two sets of U-shaped tubes 304. Electric push rods 402 are fixedly installed on the side of the symmetrically arranged support plates 401 that are close to each other. A U-shaped seat 403 is fixedly installed at the output end of the electric push rod 402. Multiple sets of second rollers 404 arranged at equal intervals are rotatably connected to the U-shaped seat 403 through a rotating shaft. The support plates 401 and the base frame 101 are fixedly connected.

[0032] In this implementation plan: the trash rack cleaning equipment used in this water conservancy project, when cleaning the trash rack (not shown in the figure), such as Figure 1 As shown: First, the trash rack is placed vertically on the base frame 101 at the position of the first roller 102. Due to the rolling design of the first roller 102, by pushing the trash rack, the trash rack comes into contact with the first roller 102, and the resulting friction drives the first roller 102 to roll, making the trash rack move more smoothly.

[0033] After the trash rack is placed at the position of the first roller 102, the electric push rod 402 is activated to drive the two sets of U-shaped seats 403 to move towards each other, and at the same time drive the second roller 404 to move synchronously until the two sets of second rollers 404 on both sides contact the sides of the trash rack. The two sets of second rollers 404 located on both sides of the trash rack can play a limiting and guiding role for the trash rack, so that the trash rack can be stably and vertically placed on the first roller 102.

[0034] Next, the water pump 301 and the drive motor 203 are started respectively. The operation of the drive motor 203 drives the brush rod 205 to rotate. At the same time, the operation of the water pump 301 draws water from the external water supply system and delivers it to the connecting pipe 302. The water is then discharged through the connecting pipe 302 into the U-shaped pipe 304 and discharged through the nozzle 303 on the U-shaped pipe 304.

[0035] Then, the trash rack is pushed to move on the first roller 102, while the second roller 404 can roll on the U-shaped seat 403, thereby reducing the friction between the second roller 404 and the trash rack. As the trash rack moves, it is initially rinsed by water discharged from the nozzle 303 on one side, which wets the trash rack. As the trash rack continues to move, the wet trash rack is cleaned by the rotation of the brush rod 205. At the same time, the trash rack continues to move, and the cleaned trash rack is rinsed again by water discharged from the nozzle 303 on the other side. When the trash rack passes the last set of nozzles 303 for rinsing, one end of the trash rack enters the guide mechanism 4 on the other side to continue the guide operation on the other end of the trash rack. When the trash rack is completely separated from the guide mechanism 4, the cleaning operation is completed.

[0036] This solution, by setting up double-sided cleaning, allows the device to clean both sides of the trash rack simultaneously, eliminating the need for manual turning, greatly improving the efficiency of the cleaning work, enhancing the effectiveness of the device, and meeting actual usage requirements.

[0037] Furthermore;

[0038] In an optional embodiment, the top of the bracket 201 is provided with a groove 204 that is adapted to the mounting base 202. The mounting base 202 can slide in the groove 204 provided in the bracket 201. A screw 206 is rotatably connected to one side of the mounting base 202 via a bearing. The bracket 201 is threadedly connected to the screw 206 via a threaded hole.

[0039] In this embodiment: as follows Figure 2 As shown: By rotating the screw 206, the mounting base 202 can be moved, and the mounting base 202 can slide within the groove 204 opened in the bracket 201. The groove 204 can limit the movement of the mounting base 202, making the movement of the mounting base 202 more stable. The position of the mounting base 202 can be adjusted by the screw 206, which in turn can adjust the distance between the two sets of brush rods 205, so that the distance between the two sets of brush rods 205 is adapted to the thickness of the trash rack, thereby improving the cleaning effect.

[0040] Furthermore;

[0041] In an optional embodiment, a water collection housing 103 for collecting sewage is placed at the bottom of the base frame 101. A drain pipe is fixedly connected to one side of the water collection housing 103, and a control valve is installed inside the drain pipe.

[0042] In this embodiment: a water collection shell 103 is provided at the bottom of the base frame 101, which can collect the flushing sewage, making it convenient for secondary filtration and reuse, thus saving water resources. A drain pipe is provided on the water collection shell 103, and a control valve is provided inside the drain pipe. By turning the control valve, the sewage inside the water collection shell 103 can be discharged from the drain pipe.

[0043] The working principle and usage process of this utility model are as follows: When using this water conservancy project trash rack cleaning equipment, to clean the trash rack (not shown in the figure), first, the trash rack is vertically placed at the position of the first roller 102 on the base frame 101. After the trash rack is placed at the position of the first roller 102, the electric push rod 402 is activated to drive the two sets of U-shaped seats 403 to move towards each other, while simultaneously driving the second roller 404 to move synchronously until the second rollers 404 on both sides contact the sides of the trash rack. Two sets of second rollers 404 are located on both sides of the trash rack, which can limit and guide the trash rack, thus ensuring that the trash rack is stably and vertically placed on the first roller 102. Then, the water pump 301 and the drive motor 203 are started respectively. The operation of the drive motor 203 drives the brush rod 205 to rotate. At the same time, the operation of the water pump 301 draws water from the external water supply system and delivers it into the connecting pipe 302. Through the connecting pipe 302, it is discharged into the U-shaped pipe 304 and sprayed through the U-shaped pipe 304. The nozzle 303 discharges water; then it pushes the trash rack to move on the first roller 102, while the second roller 404 can roll on the U-shaped seat 403, thereby reducing the friction between the second roller 404 and the trash rack. Through the movement of the trash rack, it is initially rinsed by water discharged from the nozzle 303 on one side, wetting the trash rack. As the trash rack continues to move, the wetted trash rack is cleaned by the rotation of the brush rod 205. Simultaneously, as the trash rack continues to move, the cleaned trash rack is passed through the water discharged from the nozzle 303 on the other side. The mud and dirt on the trash rack are rinsed again. When the trash rack passes the last set of nozzles 303 for rinsing, one end of the trash rack enters the guide mechanism 4 on the other side to continue guiding the other end of the trash rack. When the trash rack is completely detached from the guide mechanism 4, the cleaning operation is completed. This solution, by setting up double-sided cleaning, can clean both sides of the trash rack at the same time, avoiding the need for manual turning, greatly improving the efficiency of the cleaning work, improving the use effect of the device, and meeting the actual use needs.

[0044] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
