Description

Technical Field

[0001] The utility model relates to the technical field of trash cleaning, in particular to a trash rack cleaning mechanism which is easy to clean. Background Art

[0002] Trash racks are frame-type structures installed in front of water inlets to block debris such as aquatic plants and driftwood carried by the water flow. The main function of a trash rack is to prevent debris from entering hydraulic structures, such as pumping stations, water diversion channels, and water inlets of hydropower stations, in order to protect the normal operation of equipment such as turbines and pumps and reduce equipment wear and failure. Trash racks are generally composed of bars, frames, and support structures. The bars are usually welded or spliced ​​using materials such as flat steel and round steel, and the spacing between the bars is determined by the size of the dirt to be intercepted. The frame is used to fix the bars, and the support structure is used to install the trash rack at the water inlet. During the long-term operation of the trash rack, the accumulation of dirt will lead to a reduction in the flow area and an increase in head loss, affecting the normal operation of hydraulic structures. Therefore, it is necessary to perform cleaning operations regularly or according to the water level difference before and after the rack to restore its flow capacity.

[0003] For example, Chinese patent publication number CN217325283U discloses a trash rack cleaning mechanism, comprising: a material storage frame, which comprises a frame body, and one end of the left and right side plates of the frame body are respectively provided with a mounting plate; a cleaning roller, which is arranged on the mounting plate, and comprises a roller and multiple rows of cleaning claws arranged on the roller, and a transmission shaft is respectively provided at both ends of the roller, a sprocket is provided on the transmission shaft, a sprocket protective shell is provided outside the sprocket, and the sprocket is connected to a lifting device through a chain, and multiple rows of cleaning claws are evenly arranged in an array on the circumference of the cleaning roller. As the cleaning roller rotates, the cleaning claws can transfer the pollutants on the trash rack into the material storage frame, and the material storage frame is provided with multiple support rods staggered with the cleaning claws, and the length of the support rods is at a predetermined distance from the outer periphery of the cleaning roller, so that the pollutants stuck on the cleaning claws can be cleaned out of the cleaning claws, thereby improving the working efficiency of the cleaning claws. The middle of the cleaning roller is hollow, which can effectively reduce the overall weight of the mechanism and make the mechanism lighter. Multiple rows of through holes are provided on the circumference, so that when entering underwater operation, it will not be affected by buoyancy due to the hollowness.

[0004] Although the above example can remove the dirt intercepted by the trash rack by setting the cleaning claws, the dirt intercepted by the trash rack will accumulate a lot of sludge at the lower end of the trash rack after a long period of accumulation. The existing trash rack cleaning mechanism can only clean large impurities and is difficult to clean sludge, which is inconvenient to use. Utility Model Content

One end is fixedly connected to a rake roller 38, and both ends of the rake roller 38 are rotatably connected to an adjusting piece 39. An adjusting hole 310 is opened on the surface of the mounting shell 11, and a slide groove 311 is fixedly connected to the surface of the mounting shell 11. The internal thread of the slide groove 311 is connected to a threaded rod 312, and the surface of the threaded rod 312 is threadedly connected to an elastic piece 313 for adjusting the tightness of the second synchronous belt 36.

A brush roller 35 is fixedly connected to one side of the second synchronous wheel 34.

[0024] In this embodiment, the mechanism is hoisted onto a lift via the hoisting lugs 12. By adjusting the position of the mechanism, one end of the mounting housing 11 is moved to the side of the waste 5. Subsequently, under the action of the second motor 31, the first synchronous wheel 32 drives the first synchronous belt 33 to rotate the second synchronous wheel 34, thereby causing the brush roller 35 to brush the upper end of the trash rack 4. At the same time, the first synchronous wheel 32 drives the third synchronous wheel 37 to rotate via the second synchronous belt 36, causing the rake roller 38 to rotate. By engaging with the fixed teeth 14, the rake roller 38 breaks up large pieces of waste and simultaneously moves the silt next to the mounting housing 11 into the mounting housing 11.

[0025] Example 2

[0026] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, both ends of the brushing roller 35 are rotatably connected to the inner wall of the mounting shell 11, the top of the mounting shell 11 is fixedly connected with a lifting ear 12, the surface of the mounting shell 11 is fixedly connected with a protective shell 13, the surface of the protective shell 13 is fixedly connected to the surface of the second motor 31, the inner wall of the mounting shell 11 is fixedly connected with fixed teeth 14 meshing with the surface of the rake roller 38, and the inner wall of the mounting shell 11 is fixedly connected with a partition 15 that separates the storage cavity.

[0027] In this embodiment, the spiral blade 24 is rotated under the action of the first motor 22, and the large pieces of dirt 5 and sludge that have been crushed in the installation shell 11 are transported along the conveying pipe 23 to the storage chamber separated by the partition 15 in the installation shell 11 for storage, so that the sludge can be cleaned and it is more convenient to use.

[0028] Example 3

[0030] In this embodiment, by providing a plurality of adjustment holes 310 and elastic members 313, the adjustment member 39 can be installed into different adjustment holes 310, and the threaded rod 312 can be rotated to slide the elastic member 313 along the slide groove 311. In this way, the position of the rake roller 38 can be adjusted while adjusting the tightness of the second synchronous belt 36, making it easier to use. In addition, the provision of the exposed brush roller 35, the rake roller 38 and the open storage cavity makes the mechanism easier to clean and easier to use.

[0031] The working principle of the easy-to-clean trash rack cleaning mechanism is described in detail below.

[0032] like Figure 1-5As shown, when cleaning, the mechanism is hoisted onto the elevator through the hoisting ear 12, and by adjusting the position of the mechanism, one end of the mounting shell 11 is moved to the side of the dirt 5. Then, under the action of the second motor 31, the first synchronous wheel 32 drives the first synchronous belt 33 to rotate the second synchronous wheel 34, and then the brush roller 35 brushes the upper end of the trash rack 4. At the same time, the first synchronous wheel 32 drives the third synchronous wheel 37 to rotate through the second synchronous belt 36, so that the rake roller 38 rotates, and while engaging with the fixed teeth 14 to crush large pieces of dirt, the silt next to the mounting shell 11 is moved into the mounting shell 11. Then, under the action of the first motor 22, the spiral blade 24 rotates to remove the mounting rack 4. The crushed large pieces of dirt 5 and sludge in the shell 11 are transported along the conveying pipe 23 to the storage cavity separated by the partition 15 in the installation shell 11 for storage, so that the sludge can be cleaned, which is more convenient to use. At the same time, the setting of multiple adjustment holes 310 and elastic members 313 can be achieved by installing the adjustment members 39 into different adjustment holes 310, rotating the threaded rod 312, and making the elastic member 313 slide along the slide groove 311.
