Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a cleaning device for trash racks used in water conservancy projects. Background Technology

[0002] Water conservancy projects refer to projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Trash racks are commonly used equipment in water conservancy projects. They are mainly installed in front of the water inlet to block water plants, driftwood and other debris carried by the water flow. In order to ensure the normal flow of water during the use of trash racks, they need to be cleaned.

[0003] According to the search, the Chinese patent "A cleaning device for trash racks in water conservancy projects" with the authorization announcement number "CN221741200U" cleans the trash rack by rotating a cleaning brush. During the rotation of the cleaning brush, it will contact the limiting tooth plate, and the impurities it cleans will be removed by the limiting tooth plate, thereby improving the overall cleaning quality of the trash rack.

[0004] While the cleaning brush used in the above application can clean the trash rack simultaneously, the impurities retained on the limiting tooth plate gradually increase during the cleaning process, which reduces the cleaning effect of the limiting tooth plate on the cleaning brush and thus affects the cleaning effect of the cleaning brush on the trash rack.

[0005] Therefore, a trash rack cleaning device for water conservancy projects is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a cleaning device for trash racks in water conservancy projects to solve the above-mentioned problems. It improves the problem that when the limiting tooth plate cleans the cleaning brush, the impurities retained on the limiting tooth plate gradually increase, which leads to a decrease in the cleaning effect of the limiting tooth plate on the cleaning brush, thus affecting the cleaning effect of the cleaning brush on the trash rack.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a cleaning device for a trash rack in water conservancy projects, comprising: a fixed frame installed at the top of the trash rack; a cleaning mechanism, the cleaning mechanism including a movable frame slidably connected to one side of the fixed frame, an electric cleaning brush rotatably connected to the inner wall of the movable frame, an installation frame slidably connected to the other side of the movable frame, a fixed plate fixedly connected to the inner wall of the installation frame, a plurality of evenly distributed collection plates fixedly connected to one side of the fixed plate, the collection plates being inclined, a plurality of evenly distributed cleaning plates fixedly connected to the other side of the collection plates, a scraper slidably connected to the top of the collection plates, collection frames embedded in both sides of the inner wall of the installation frame, and a driving component provided on the other side of the fixed plate.

[0008] Preferably, the drive assembly includes a first motor fixedly connected to the surface of the mounting frame. The output shaft of the first motor passes through the mounting frame and is fixedly connected to a reciprocating lead screw. A moving rod is provided on the surface of the reciprocating lead screw. A sliding rod is fixedly connected to one side of each of the plurality of scrapers. The other end of each of the plurality of sliding rods passes through a fixed plate and is fixedly connected to one side of the moving rod. This facilitates the driving of the moving rod to drive the corresponding scraper to reciprocate in the horizontal direction through the multiple sliding rods.

[0009] Preferably, two limiting rods are fixedly connected to one side of the mounting frame, and a sliding groove matching the limiting rods is provided on the other side of the movable frame. This ensures that the mounting frame and the movable frame maintain vertical movement during installation and disassembly, reducing the difficulty of installation and disassembly.

[0010] Preferably, multiple collecting plates are disposed between opposite sides of two collecting frames, and multiple through holes are provided at the bottom end of each collecting frame. This facilitates the drainage of the aqueous solution within the collecting frames when the mounting frame is removed from the water.

[0011] Preferably, the cleaning plate is inclined, and the inclination angle of the cleaning plate is smaller than that of the collection plate. This facilitates the movement of debris on the cleaning plate towards the top of the collection plate.

[0012] Preferably, the surface of the fixing plate is provided with multiple limiting grooves, and the surface of the slide rod is slidably connected to the inner wall of the corresponding limiting groove. This helps to limit the movement path of the scraper and ensures the stability of the scraper when scraping away debris above the collection plate during its movement.

[0013] Preferably, a pull rod is fixedly connected to the top of the mounting frame, and a rubber ring is fixedly connected to the surface of the pull rod. This facilitates the removal of the mounting frame from the water by the operator.

[0014] The beneficial effects of this utility model are:

[0015] 1. The above-mentioned cleaning mechanism uses an electric cleaning brush to clean the trash rack. Multiple cleaning plates simultaneously scrape off the impurities cleaned by the electric cleaning brush. During the scraping process, the inclined surface at the top of the cleaning plate helps to move the debris on the cleaning plate upwards to the collection plate. Through the drive component, multiple scrapers are driven to move back and forth on the corresponding collection plates, pushing the debris on the collection plates into the collection frame for collection. This avoids the accumulation of debris on the collection plates and ensures that the debris cleaned by the cleaning plates can move smoothly to the collection plates, thus preventing the accumulation of debris on the cleaning plates and improving the cleaning effect of the cleaning plates on the electric cleaning brush, thereby ensuring the cleaning effect of the electric cleaning brush on the trash rack.

[0016] 2. When removing the installation frame from the water to clean the collected debris, multiple through holes are provided to facilitate the drainage of the aqueous solution inside the collection frame. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] In practical implementation: such as Figure 1-5As shown, a cleaning device for a trash rack in a water conservancy project includes: a fixed frame 100 installed at the top of the trash rack; a cleaning mechanism 200, the cleaning mechanism 200 including a movable frame 210 slidably connected to one side of the fixed frame 100, an electric cleaning brush 211 rotatably connected to the inner wall of the movable frame 210, an installation frame 220 slidably connected to the other side of the movable frame 210, a fixed plate 230 fixedly connected to the inner wall of the installation frame 220, a plurality of evenly distributed collection plates 240 fixedly connected to one side of the fixed plate 230, the collection plates 240 being inclined, a plurality of evenly distributed cleaning plates 250 fixedly connected to the other side of the collection plates 240, a scraper 260 slidably connected to the top of the collection plates 240, collection frames 270 embedded in both sides of the inner wall of the installation frame 220, and a drive assembly 280 provided on the other side of the fixed plate 230.

[0025] In this embodiment, a lead screw is rotatably connected to the inner wall of the fixed frame 100, and a moving block is threadedly connected to the surface of the lead screw. One side of the moving block is fixedly connected to one side of the fixed frame 100. A second motor is fixedly connected to one end of the fixed frame 100, and one end of the lead screw is fixedly connected to the output shaft of the second motor. When the second motor is started by the controller to drive the lead screw to rotate, the moving block will drive the fixed frame 100 to move horizontally.

[0026] like Figure 2 and Figure 4 As shown, the drive assembly 280 includes a first motor 281 fixedly connected to the surface of the mounting frame 220. The output shaft of the first motor 281 passes through the mounting frame 220 and is fixedly connected to a reciprocating screw 282. A moving rod 283 is provided on the surface of the reciprocating screw 282. A sliding rod 284 is fixedly connected to one side of each of the multiple scrapers 260. The other end of each of the multiple sliding rods 284 is fixedly connected to a through fixed plate 230 and to one side of the moving rod 283.

[0027] In this embodiment, the first motor 281 is started by the controller. The output shaft of the first motor 281 drives the reciprocating screw 282 to rotate. The reciprocating screw 282 is in the form of two threaded grooves with the same pitch and opposite directions of rotation, and the two ends are connected by a transition curve. The rotation of the reciprocating screw 282 causes the side of the spiral groove to push the slider placed in the spiral groove to perform axial reciprocating motion. Therefore, when the reciprocating screw 282 rotates, it will drive multiple sliders 284 to reciprocate through the moving rod 283.

[0028] like Figure 2 and Figure 4 As shown, two limiting rods 221 are fixedly connected to one side of the mounting frame 220, and a sliding groove 212 matching the limiting rods 221 is provided on the other side of the moving frame 210. A pull rod 290 is fixedly connected to the top of the mounting frame 220, and a rubber ring is fixedly connected to the surface of the pull rod 290.

[0029] In this embodiment, in the initial state, the limiting rod 221 is placed in the corresponding slide groove 212, and the mounting frame 220 and the moving frame 210 are fixed by bolts. When the mounting frame 220 and the moving frame 210 are removed, the bolts are released, and the mounting frame 220 is pulled upward by the pull rod 290. Under the action of the slide groove 212 and the limiting rod 221, the mounting frame 220 will move vertically upward.

[0030] like Figure 3 and Figure 5 As shown, multiple collection plates 240 are disposed between the opposite sides of two collection frames 270, and multiple through holes 271 are provided at the bottom of the collection frame 270.

[0031] In this embodiment, a detachable cover plate is provided on the other side of the collection frame 270. The cover plate is fixed to the collection frame 270 by bolts. When the installation frame 220 is removed from the water, the through hole 271 can drain the aqueous solution in the collection frame 270.

[0032] like Figure 4 As shown, the cleaning plate 250 is inclined, and the inclination angle of the cleaning plate 250 is smaller than the inclination angle of the collection plate 240.

[0033] In this embodiment, the overall shape of the cleaning plate 250 is triangular, and the cleaning plate 250 cleans the debris on the electric cleaning brush 211 during the rotation process.

[0034] like Figure 4 As shown, the surface of the fixing plate 230 is provided with multiple limiting grooves 285, and the surface of the slide rod 284 is slidably connected to the inner wall of the corresponding limiting groove 285.

[0035] In this embodiment, the slide bar 284 can move to the inner side of the collection box 270 along the farthest moving distance of the limiting groove 285.

[0036] In use, this invention starts the electric cleaning brush 211 to rotate while simultaneously driving the moving frame 210 to move horizontally to clean the trash rack. While the electric cleaning brush 211 rotates, multiple cleaning plates 250 simultaneously scrape away the debris cleaned by the brush. During this scraping process, the debris on the cleaning plates 250 moves upwards towards the collection plate 240 due to the tilting effect of their tops. At the same time, the controller starts the first motor 281 in the drive assembly 280. The output shaft of the first motor 281 drives the reciprocating screw 282 to rotate, thereby driving the moving rod 283 to move the corresponding scraper 260 horizontally via multiple sliding rods 284. During this reciprocating movement, the scraper 260 pushes the debris above the collection plate 240, which then enters the collection frame 270 for collection. This prevents the debris from accumulating on the cleaning plates 250 and ensures the effective cleaning of the electric cleaning brush 211 by the cleaning plates 250.

[0037] After cleaning the trash rack, when cleaning the debris collected in the collection frame 270, disconnect the installation frame 220 and the movable frame 210, remove the installation frame 220, and then remove the cover plate of the collection frame 270 to clean the debris collected in the collection frame 270.

[0038] It should be noted that the motors and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. The motor can be powered by a built-in power supply or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
