Description
Technical Field
[0001] This utility model relates to the field of water conservancy design, and in particular to a debris-blocking device for drainage ditches in water conservancy design. Background Technology
[0002] Drainage ditches are ditches that direct water collected in side ditches, intercepting ditches, and low-lying areas near roadsides, farmland, and residences to areas outside these areas. Their main functions include drainage, irrigation, flood control, and water distribution. During the rainy season, drainage ditches effectively solve urban flooding problems and discharge wastewater, helping to ensure people's daily travel. However, drainage ditches often carry various types of garbage during the drainage process. This garbage, carried by the water flow, not only affects the environment but may also hinder the normal operation of subsequent water conservancy facilities. Some drainage ditches are equipped with barrier nets, but after a period of time, a large amount of garbage accumulates in front of the nets, causing blockages. Therefore, we need to design a device that can clean up garbage in drainage ditches. Utility Model Content
[0003] In view of the shortcomings of the existing technology, this utility model provides a debris interception device for drainage ditches in hydraulic design, which solves the problem that garbage is washed away by water flow and affects the downstream environment or gets stuck in the interception net and causes drainage ditch blockage.
[0004] According to an embodiment of this utility model, a debris-blocking device for a drainage ditch in hydraulic design includes a baffle, a fixed frame, a threaded rod, a first motor, a movable housing, and a drive assembly. The baffle is vertically installed within the drainage ditch, with a mesh structure in the middle. The two sides of the baffle are slidably connected to the two side walls of the drainage ditch in the vertical direction. The bottom of the threaded rod is threadedly connected to the middle of the baffle. The first motor and the fixed frame are fixedly installed, and the output shaft of the first motor is fixedly connected to the top of the threaded rod. The movable housing is a cuboid adapted to the drainage ditch, slidably connected to the two side walls of the drainage ditch in the vertical direction and close to the baffle. The front and left sides of the movable housing near the baffle are open, and the movable housing, except for the bottom, has a mesh structure. The drive assembly drives the movable housing to move vertically and rotate to an inclined state.
[0005] The technical principle of this utility model is as follows: the movable box is placed in the drainage ditch. When there is a certain amount of garbage in the movable box, the driving component causes the movable box to move upward and dump the garbage out of the drainage ditch. During this process, the baffle prevents the drainage ditch from continuing to flow downward.
[0006] Preferably, the drive assembly includes a second motor and a third motor, a first rotating rod, a second rotating rod, two second traction ropes, two third traction ropes, and a pulling unit. The first rotating rod and the second rotating rod are respectively disposed above the left and right sides of the movable box. Both ends of the first rotating rod and the second rotating rod are fixedly provided with winding drums. The first traction rope and the second traction rope are respectively fixedly connected to the winding drums at both ends of the first rotating rod and the second rotating rod. The other ends of the first traction rope and the second traction rope are respectively fixedly connected to the ends of the left and right sides of the movable box. The second motor and the third motor are used to drive the first rotating rod and the second rotating rod to rotate.
[0007] Preferably, an extension plate is slidably provided at the bottom of the movable box, and the extension plate is parallel to the bottom of the movable box; a hook or hanging hole is provided on the left side of the extension plate.
[0008] Preferably, a rotating door panel is provided on the left side of the movable box, and the top of the rotating door panel is hinged to the top of the movable box.
[0009] Preferably, a trash can is provided on the right side of the drainage ditch, near the movable box.
[0010] Preferably, guide rails are fixedly installed on all four vertical sides of the movable box, and four guide grooves are fixedly installed on the side wall of the drainage ditch, with an inlet angle at the top of the guide groove.
[0011] Preferably, the guide groove protrudes upwards from the plane where the drainage ditch is located.
[0012] Compared to existing technologies, this invention offers the following advantages: When water flows downwards from the drainage ditch, the garbage it carries is intercepted inside the movable container. Subsequently, through the action of the drive component, the movable container moves upwards and detaches from the drainage ditch. At this time, the bottom plate rotates upwards, causing the garbage to be discharged from one side to the outside of the movable container. Afterwards, the movable container moves back into the drainage ditch to continue intercepting garbage carried by the flowing water. In this way, garbage is not swept downstream, thereby protecting the environment along the water flow route and ensuring the safe operation of water conservancy facilities.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0018] like Figure 1 As shown in the figure, this utility model embodiment proposes a debris-blocking device for drainage ditches in hydraulic design, including a baffle 14, a fixing frame 2, a threaded rod 15, a first motor 17, a movable box 7, and a drive assembly. The baffle 14 is vertically arranged in the drainage ditch 1. The middle part of the baffle 14 has a mesh structure, and the outer frame of the baffle 14 is a rigid frame. The two sides of the baffle 14 are slidably connected to the two side walls of the drainage ditch 1 in the vertical direction. Guide grooves 19 are provided on both sides of the drainage ditch 1. The thickness of the baffle 14 is adapted to the guide grooves 19. The bottom of the threaded rod 15 is threadedly connected to the middle part of the baffle 14. A vertically positioned threaded sleeve 16 is fixedly arranged in the middle part of the baffle 14. The threaded rod 15 and the threaded sleeve 16 cooperate. The length of the threaded sleeve 16 is the same as the height of the baffle 14. The first motor 17 and the fixed frame 2 are fixedly installed. The output shaft of the first motor 17 is fixedly connected to the top end of the threaded rod 15. When the first motor 17 drives the threaded rod 15 to rotate, the baffle 14 moves vertically. The movable box 7 is a cuboid adapted to the drainage ditch 1. The two side walls of the movable box 7 and the drainage ditch 1 are slidably connected vertically and close to the baffle 14. The front and left sides of the movable box 7 near the baffle 14 are open. When the movable box 7 is in the drainage ditch 1, garbage enters the interior of the movable box 7 from the front. When the movable box 7 moves upward away from the drainage ditch 1, the garbage is discharged from the left side. Except for the bottom, the movable box 7 is a mesh structure, which reduces the weight of the movable box 7 and allows garbage to slide smoothly on the bottom plate 8. The drive assembly is used to drive the movable box 7 to move vertically and rotate to an inclined state. When the movable box 7 moves upward, the left side with the opening abuts against the side wall of the drainage ditch 1, thereby preventing garbage from overflowing. When the movable box 7 leaves the drainage ditch 1, the baffle 14 moves into the drainage ditch 1.
[0019] like Figure 2As shown, preferably, the drive assembly includes a second motor 4 and a third motor 6, a first rotating rod 3, a second rotating rod 5, two second traction ropes 11, two third traction ropes 12, and a pulling unit. The first rotating rod 3 and the second rotating rod 5 are respectively positioned above the left and right sides of the movable housing 7. The first rotating rod 3, the second rotating rod 5, and the fixed frame 2 are rotatably connected. The first rotating rod 3, the second rotating rod 5, and the left and right sides of the movable housing 7 are parallel. A winding drum 18 is fixedly installed at both ends of the first rotating rod 3 and the second rotating rod 5. One end of the first traction rope 10 and the second traction rope 11 are fixedly connected to the winding drums 18 at both ends of the first rotating rod 3 and the second rotating rod 5, respectively. The other ends of the first traction rope 10 and the second traction rope 11 are fixedly connected to the ends of the left and right sides of the movable housing 7, respectively. The second motor 4 and the third motor 6 are used to drive the first rotating rod 3 and the second rotating rod 5 to rotate. The pulling unit is used to pull the base plate 8 to rotate upwards. The second motor 4 and the third motor 6 work synchronously, ensuring a stable state during vertical movement. When the movable container 7 leaves the water surface, the second motor 4 and the third motor 6 rotate asynchronously, causing the movable container 7 to tilt and the garbage to be discharged from the left side.
[0020] like Figure 2 As shown, preferably, an extension plate 21 is slidably provided at the bottom of the movable box 7, and the extension plate 21 is parallel to the bottom of the movable box 7. A hook or hanging hole is provided on the left side of the extension plate 21. The width of the extension plate 21 and the discharge port on the left side of the movable box 7 are the same. When the movable box 7 is above the water surface, the second motor 4 and the third motor 6 rotate asynchronously, causing the movable box 7 to be in an inclined state. Before the garbage falls, the worker pulls the extension plate 21 out by connecting the pull rod and the hook or hanging hole. After the garbage comes out of the movable box 7, it continues to slide along the extension plate 21 for a distance before falling. This prevents the garbage from falling into the drainage ditch. When the movable box 7 returns to the bottom of the movable box 7, the extension plate 21 returns to its original position.
[0021] Preferably, a rotating door panel is provided on the left side of the movable container 7, and the top of the rotating door panel is hinged to the top of the movable container 7. When the movable container 7 continues to rise after leaving the drainage ditch 1, the rotating door panel can close the garbage inside, preventing the garbage from falling from the side during the ascent.
[0022] Preferably, a trash can 13 is located on the right side of the drainage ditch 1, near the movable container 7. After the movable container 7 moves upward beyond the height of the trash can 13, the base plate 8 begins to tilt, allowing the trash to fall into the trash can 13 and then be transported by staff.
[0023] Preferably, guide rails 20 are fixedly installed on all four vertical sides of the movable box 7, and four guide grooves 19 are fixedly installed on the sidewalls of the drainage ditch 1. Each guide groove 19 has a guide angle at its top, which is a trumpet-shaped structure. The guide rails 20 provide support for the movable box 7 when the drainage ditch 1 is impacted by water flow. When the movable box 7 moves upward to discharge the waste and returns to the drainage ditch 1, the guide angles correct any slight deviation.
[0024] Preferably, the guide groove 19 protrudes upward from the plane of the drainage ditch 1 to avoid or reduce the falling of gravel or debris from the top of the guide groove 19, which would affect the smoothness of the guide groove 19.
[0025] Finally, it should be noted that 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 preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
