DETAILED DESCRIPTION

[0021] The present application will be further described below in conjunction with specific embodiments, wherein the drawings are only used for exemplary description, and the representation is only a schematic view, not a physical view, and cannot be understood as a limitation on the present patent, in order to better illustrate the specific embodiments of the present application, some components of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product, it can be understood by those skilled in the art that some known structures and their descriptions in the drawings can be omitted, based on the specific embodiments in the present application, all other specific embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0022] Example 1

[0023] As Figures 1-5 ​As shown, a reservoir drainage outlet with automatic sludge removal function includes a drainage channel 1. A fixed cover 2 is fixedly connected to the top right side of the drainage channel 1. A crankshaft 3 is rotatably connected to the inside of the fixed cover 2. An impeller 4 is fixedly connected to the outside of the crankshaft 3. A rotating rod 5 is rotatably connected to the center of the outside of the crankshaft 3. The other end of the rotating rod 5 is rotatably connected to a fixed rod 6 via a rotating shaft. A fixed sleeve 7 is provided on the outside of the fixed rod 6, and the fixed sleeve 7 is fixedly connected to the drainage channel 1. A scraper 9 is provided on the outside of the fixed rod 6. A gate 16 penetrating the drainage channel 1 is contacted on the right side of the inside of the drainage channel 1. A multi-stage electric push rod 17 penetrating the gate 16 is fixedly connected to the top of the gate 16, and the bottom end of the multi-stage electric push rod 17 is fixedly connected to the drainage channel 1.

[0024] Example 2

[0025] like Figures 2-3 As shown, in order to solve the problem of large friction between the fixed rod 6 and the fixed sleeve 7 during the reciprocating motion, the inner side of the fixed sleeve 7 is rotatably connected with symmetrically distributed balls 8, and the balls 8 are in contact with the fixed rod 6. By making the fixed sleeve 7 contact the fixed rod 6 through the balls 8, large friction between the fixed rod 6 and the fixed sleeve 7 during the reciprocating motion is avoided.

[0026] Example 3

[0027] like Figure 2 As shown, in order to solve the problem of poor scraping effect of silt in drainage channel 1, the scraping frame 9 is in contact with drainage channel 1, and the distance between adjacent scraping frames 9 is equal to the maximum movement distance of scraping frame 9. By making the distance between adjacent scraping frames 9 equal to the maximum movement distance of scraping frame 9, the scraping effect of silt in drainage channel 1 is better when the scraping frame 9 is controlled to scrape the inside of drainage channel 1.

[0028] Example 4

[0029] like Figures 2-4 As shown, to address the problem of inconvenience in replacing the scraper frame 9 when it is worn, broken, or damaged, a bidirectional threaded shaft 10 with opposite thread directions on both sides is rotatably connected to the inner side of the fixing rod 6. Both ends of the bidirectional threaded shaft 10 are helically connected to cuboid-shaped ferrules 11, which are slidably connected to the fixing rod 6. The ferrules 11 are engaged with the scraper frame 9. A rotating block 12 is fixedly connected to the center of the outer side of the bidirectional threaded shaft 10. When the scraper frame 9 is worn, broken, or damaged, the rotating block 12 controls the helically connected bidirectional threaded shaft 10 with opposite thread directions on both sides to the cuboid-shaped ferrules 11, further allowing the ferrules 11 to be retracted within the fixing rod 6 and disengaged from the scraper frame 9. This facilitates the replacement of the damaged scraper frame 9 with a new one.

[0030] Example 5

[0031] As Figure 1 , Figure 2 and Figure 5 shown, in order to solve the problem that the silt inside the drainage channel 1 cannot be conveniently controlled to stop the cleaning mechanism after a certain cleaning time to reduce the wear of the scraping frame 9, the top end of the fixed cover 2 is rotatably connected with a fixed threaded shaft 13 penetrating through the fixed cover 2, the outer bottom end of the fixed threaded shaft 13 is screw-connected with a tooth block 14 slidingly connected with the fixed cover 2, the bottom end of the tooth block 14 is provided with a gear 15, and the gear 15 is fixedly connected with the crankshaft 3. After the silt inside the drainage channel 1 reaches a certain cleaning time, the fixed threaded shaft 13 is screw-connected with the tooth block 14 by rotating, and the tooth block 14 is further meshed with the gear 15 on the outer side of the crankshaft 3, so that the impeller 4 cannot continue to drive the crankshaft 3 to rotate under the impact of water flow, which facilitates the fixed rod 6 to stop driving the scraping frame 9 to reciprocate after the drainage channel 1 completes the fixed-time desilting, and further reduces the wear of the scraping frame 9.

[0032] In this embodiment, when the multi-stage electric push rod 17 is controlled to extend by an external control mechanism, and the gate 16 inside the reservoir drainage channel 1 is further controlled to open for drainage, after the gate 16 is completely opened, the impeller 4 is rotated by water flow impact, and further drives the crankshaft 3 to rotate, so that the fixed rod 6 moves in the fixed sleeve 7 by reciprocating the rotating rod 5, the scraping frame 9 is controlled to reciprocate left and right in the drainage channel 1 by the fixed rod 6 and the clamping sleeve 11, and then the silt at the bottom of the drainage channel 1 is separated from the drainage channel 1 by the reciprocating scraping of the scraping frame 9, and the silt after scraping is impacted by water during the drainage process, which facilitates automatic cleaning of the silt in the drainage channel 1. When the drainage channel 1 completes the fixed-time desilting operation, the tooth block 14 is further meshed with the gear 15 on the outer side of the crankshaft 3 by screwing the fixed threaded shaft 13 and the tooth block 14, so that the impeller 4 cannot continue to drive the crankshaft 3 to rotate under the impact of water flow, and the fixed rod 6 can stop driving the scraping frame 9 to reciprocate after the drainage channel 1 completes the fixed-time desilting, so that the wear of the scraping frame 9 can be reduced, and the service life thereof can be prolonged. When some of the scraping frames 9 are found to be severely worn and broken after a long time of use during subsequent maintenance of the device, the clamping sleeve 11 is further retracted in the fixed rod 6 and disengaged from the scraping frame 9 by screwing the bidirectional threaded shaft 10 with opposite threaded directions on both sides and the clamping sleeve 11 in the shape of a rectangular parallelepiped by the rotating block 12, which facilitates the replacement of the damaged scraping frame 9 after it is removed.

[0033] The above is the preferred embodiment of the present application, the basic principle and main features of the present application and the advantages of the present application are shown and described, those skilled in the art should understand that the present application is not limited by the above examples, the above examples and the description in the specification are only to illustrate the principle of the present application, without departing from the spirit and scope of the present application, the present application will also have various changes and improvements, these changes and improvements all fall within the scope of the present application, the scope of protection of the present application is defined by the appended claims and their equivalents.
