Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a device for dredging water channels used in water conservancy and hydropower construction. Background Technology

[0002] Water conservancy and hydropower projects are widely used in daily life, especially water canals, which are widely used in agricultural irrigation. However, during long-term use, a large amount of silt and debris will accumulate inside the canals, affecting the water flow. At the same time, a large amount of silt will be carried into the farmland, affecting the growth of crops. In order to ensure the water flow of the canals, it is necessary to dredge them. During the dredging process, some sewage is present in the canals, which can facilitate the extraction of silt and improve the fluidity of the silt.

[0003] As shown in the reference case "A Dredging Device for Water Conservancy and Hydropower Construction Canals" (Announcement No. CN221142896U), this utility model uses a hydraulic cylinder to extend and retract, causing a slider to slide inside a slide rail rod. This causes the base plate and moving wheels to move closer together, ensuring that the moving wheels on both sides are positioned at the edge of the canal body. This activates the moving wheels, propelling the top plate forward. The top plate's movement then propels the connecting rod and push plate forward along the inner wall of the canal body. The width can be adjusted, allowing the device to adapt to canals of different widths and thus have a wider range of applications.

[0004] The aforementioned patent uses movable wheels to push and scrape the silt accumulated inside the water channel. However, during use, the filter holes on the surface of the push plate are easily blocked by the silt scooped up by the shovel, causing silt to accumulate inside the push plate and shovel. Under long-term high-load operation, the internal equipment of the drive device that drives the movable wheels overheats, causing damage to the drive device and affecting the normal use of the equipment. Utility Model Content

[0005] Therefore, it is necessary to provide a dredging device for water conservancy and hydropower construction canals to address the problem that the filter holes on the surface of the push plate are easily blocked by the silt scooped up by the shovel plate during use, resulting in silt accumulation inside the push plate and shovel plate. Under long-term high-load operation, the internal equipment of the drive device that drives the moving wheels overheats, causing damage to the drive device and affecting the normal use of the equipment.

[0006] A dredging device for water conservancy and hydropower construction canals includes: a dredging device, which is installed above the main body of the canal and is used to clean the silt accumulated inside the main body of the canal. The dredging device includes a top frame, a moving component, and a sludge scraping component. The moving component is installed below the top frame. The sludge scraping component includes a push plate and a scraper. The push plate is installed on the bottom surface of a fixed frame. The top of the fixed frame is fixedly installed to the top frame. A hydraulic telescopic rod is provided on the top surface of the push plate. The working end of the hydraulic telescopic rod passes through the top surface of the push plate and is connected to the scraper. The end sidewall of the scraper is slidably connected to the sidewall of the push plate. An auxiliary mud scraping assembly is provided on the back side wall of the push plate.

[0007] In one embodiment, guide rods are provided on both sides of the top surface of the scraper at the working end of the hydraulic telescopic rod. The ends of the guide rods pass through the top surface of the fixing frame and are slidably connected to the top surface of the push plate. A shovel plate is provided on the bottom side wall of the push plate, and the shovel plate is slidably connected to the inner bottom surface of the water channel body.

[0008] In one embodiment, the auxiliary sludge scraping assembly includes a scraper blade disposed at the end of a rotating shaft. The end of the rotating shaft passes through a protective cover and is connected to a side bevel gear. The top of the side bevel gear meshes with an upper bevel gear. The top of the upper bevel gear passes through the top surface of a mounting bracket and is keyed to the output shaft of a rotary motor disposed on the top surface of the mounting bracket.

[0009] In one embodiment, the bottom surface of the fixing frame is provided with a protective cover outside the upper bevel gear.

[0010] In one embodiment, the scraper and scraper strip are respectively disposed on both sides of the push plate.

[0011] In one embodiment, the inner bottom surface of the top frame is provided with a sliding groove, and a bidirectional screw is rotatably arranged inside the sliding groove. One end of the bidirectional screw passes through the side wall of the top frame and is keyed to the output shaft of the drive motor. The drive motor is fixedly installed on the outer side wall of the top frame. Adjustment frames are threaded on the outer arc surfaces on both sides of the bidirectional screw, and wheels are provided at both ends of the outer side walls of the two sets of adjustment frames.

[0012] In one embodiment, the end sidewalls of the two sets of adjustment frames are slidably connected to the inner wall of the slide groove.

[0013] In one embodiment, a controller is provided on the top of the top frame, and handrails are provided on the two side walls of the top frame. Beneficial effects

[0014] 1. The above-mentioned dredging device for water channels has liftable scrapers installed on both sides of the push plate. When the top frame is driven forward by the wheels below to clean the silt accumulated inside the water channel, the scraper scoops up the silt in the water channel, and the sewage in the silt is discharged through the filter holes on the surface of the push plate. The liftable scraper removes the silt adhering to the mud-facing side of the push plate, which can prevent the filter holes on the surface of the push plate from being blocked and ensure its normal use. 2. The above-mentioned dredging device also has a rotatable scraper on the back of the push plate. The upper bevel gear is driven to rotate by a rotary motor, which in turn drives the side bevel gear to rotate, so that the scraper rotates along the surface of the push plate to scrape off and clean the silt flowing out of the filter holes on the surface of the push plate, thus preventing the silt from clogging the filter holes.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-5 This utility model describes a device for dredging water channels used in water conservancy and hydropower construction.

[0020] In one embodiment, a dredging device for a water conservancy and hydropower construction canal includes: a dredging device 200, which is installed above the canal for cleaning the silt accumulated inside the canal. The dredging device 200 includes a top frame 201, a moving component, and a scraping component. The moving component is installed below the top frame 201. The scraping component includes a push plate 205 and a scraper 207. The push plate 205 is installed on the bottom surface of a fixed frame 210. The top of the fixed frame 210 is fixedly installed with the top frame 201. A hydraulic telescopic rod 208 is provided on the top surface of the push plate 205. The working end of the hydraulic telescopic rod 208 passes through the top surface of the push plate 205 and is connected to the scraper 207. The end sidewall of the scraper 207 is slidably connected to the sidewall of the push plate 205. An auxiliary mud scraping component is provided on the back side wall of the push plate 205; like Figure 2 , Figure 3 and Figure 4 As shown, guide rods 209 are provided on both sides of the top surface of scraper 207 at the working end of hydraulic telescopic rod 208. The end of guide rod 209 passes through the top surface of fixed frame 210 and is slidably connected to the top surface of push plate 205. A shovel plate 206 is provided on the bottom side wall of push plate 205. The shovel plate 206 is slidably connected to the inner bottom surface of water channel. In this embodiment, by connecting the top of the scraper 207 to the working end of the hydraulic telescopic rod 208, when the scraper 206 scrapes and cleans the silt inside the water channel, the scraper 206 scoops up the silt, and the silt is pushed and squeezed against the side wall of the push plate 205. The sewage inside the silt is discharged through the filter holes opened on the surface of the push plate 205. The controller 100 controls the extension frequency of the hydraulic telescopic rod 208, and then the hydraulic telescopic rod 208 pushes the scraper 207 to move up and down repeatedly, so as to scrape the silt accumulated on the surface of the push plate 205 through the scraper 207, so as to avoid the silt clogging the filter holes on the surface of the push plate 205, which would prevent the sewage from being discharged and affect the normal use of the push plate 205. like Figure 3 and Figure 4As shown, the auxiliary sludge scraping assembly includes a scraper 215, which is disposed at the end of a rotating shaft. The end of the rotating shaft passes through a protective cover 211 and is connected to a side bevel gear 214. The top of the side bevel gear 214 meshes with an upper bevel gear 213. The top of the upper bevel gear 213 passes through the top surface of a fixing frame 210 and is keyed to the output shaft of a rotary motor 212 disposed on the top surface of the fixing frame 210. In this embodiment, a rotatable scraper 215 is provided on the back of the push plate 205. The controller 100 controls the rotary motor 212 to drive the upper bevel gear 213 to rotate, and the side bevel gear 214 is driven to drive the scraper 215 at the end of the rotating shaft to rotate, so as to scrape off the sludge on the back side wall of the push plate 205. like Figure 4 As shown, a protective cover 211 is provided on the bottom surface of the fixed frame 210 outside the upper bevel gear 213, and the scraper 207 and scraper strip 215 are respectively provided on both sides of the push plate 205. In this embodiment, a protective cover 211 is provided on the outside of the upper bevel gear 213 to protect the upper bevel gear 213 and the side bevel gear 214, so as to prevent silt from clogging the upper bevel gear 213 and the side bevel gear 214 and affecting their normal use. In addition, a scraper 207 and a scraper 215 are respectively provided on both sides of the push plate 205. The scraper 207 and the scraper 215 scrape the silt on both sides of the push plate 205, thereby increasing the efficiency of cleaning the silt on both sides of the push plate 205. like Figure 5 As shown, a sliding groove 216 is provided on the inner bottom surface of the top frame 201. A bidirectional screw 217 is rotatably installed inside the sliding groove 216. One end of the bidirectional screw 217 passes through the side wall of the top frame 201 and is keyed to the output shaft of the drive motor 218. The drive motor 218 is fixedly installed on the outer side wall of the top frame 201. Adjustment frames 203 are threaded on the outer arc surfaces on both sides of the bidirectional screw 217. Wheels 204 are provided at both ends of the outer side walls of the two sets of adjustment frames 203. The end sidewalls of the two sets of adjustment frames 203 are slidably connected to the inner wall of the slide 216. A controller 100 is provided on the top of the top frame 201, and handrails 202 are provided on the two sidewalls of the top frame 201 respectively. In this embodiment, during use, the bidirectional screw 217 is driven to rotate by the drive motor 218, which causes the adjusting brackets 203, which are threaded on the outside of both ends of the bidirectional screw 217, to move relative to each other or in opposite directions. This allows the distance between the two sets of adjusting brackets 203 and the outer wheels 204 to be adjusted according to the width of the water channel. At the same time, a controller 100 is provided on the top of the top frame 201. The controller 100 controls the drive device inside the wheels 204 to drive the wheels 204 forward. During the driving of the wheels 204, the shovel plate 206 shovels up the silt inside the water channel. Working principle: When in use, the worker controls the drive motor 218 to start through the controller 100, which drives the bidirectional screw 217 to rotate, thereby causing the two sets of adjustment frames 203 to move relative to each other or in opposite directions, so as to adjust the distance between the wheels 204. After adjustment, the controller 100 controls the drive device inside the wheel 204 to drive the wheel 204 to rotate and move forward. The wheel 204 drives the push plate 205 set at the front end of the top frame 201 to move forward. The shovel 206 set at the bottom of the push plate 205 shovels up the silt inside the water channel. The sewage in the shoveled silt is discharged through the filter holes on the side wall of the push plate 205. However, when there is a lot of silt, the hydraulic telescopic rod 208 drives the scraper 207 to move up and down. The scraper 207 scrapes off the silt accumulated on the surface of the push plate 205 to avoid silt and garbage clogging the push plate 205, affecting the discharge of sewage in the silt and affecting the dredging efficiency. Furthermore, a rotatable scraper 215 is provided on the back of the push plate 205. The scraper 215 is used to scrape and clean the sludge seeping out from the back of the push plate 205, further ensuring that the push plate 205 can be used normally.

[0021] Additional notes: It should be noted that the hydraulic telescopic rod 208, rotary motor 212, drive motor 218, and wheel 204 with built-in drive device mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the hydraulic telescopic rod 208, rotary motor 212, drive motor 218, and wheel 204 with built-in drive device can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0022] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
