DETAILED DESCRIPTION

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a height-adjustable flood prevention device, including a flood embankment 1, a receiving groove 2 is opened on the top of the flood embankment 1, and a baffle 3 is slidably connected to the inner wall of the receiving groove 2, and a self-adjusting component 4 is arranged inside the flood embankment 1, and the self-adjusting component 4 includes: a piston groove 40, a movable plate 41, a fixed rod 42, a cavity 43, a gear 1 44, a resistance rod 45, an arc-shaped slide groove 46, a connecting cavity 47, a gear 2 48, a worm 400, a reset member 49, a fixed ring 490, a spiral spring 491, a worm wheel 401, and a rotating rod 402.

[0021] The piston groove 40 is provided on the left side of the flood embankment 1, and the inner wall piston of the piston groove 40 is connected with a movable plate 41, and a fixing rod 42 is fixed on the surface of the movable plate 41, and a cavity 43 is provided inside the flood embankment 1, and a connecting cavity 47 is provided inside the flood embankment 1, and the end of the fixing rod 42 away from the movable plate 41 passes through the cavity 43 and the flood embankment 1, and the fixing rod 42 is slidably connected with the flood embankment 1, and the inner wall of the cavity 43 is rotatably connected with a gear 1 44, and the end of the fixing rod 42 away from the movable plate 41 passes through the gear 1 44, and an arc-shaped sliding groove 46 is provided on the surface of the fixing rod 42, and a resisting rod 45 is fixed on the inner wall of the gear 1 44, and the inner wall of the connecting cavity 47 is rotatably connected with a gear 2 48, and the gear 2 48 passes through the connecting cavity 47 and the cavity 43, and the gear 2 48 meshes with the gear 1 44, and the gear A worm 400 is fixed to the surface of the second gear 48, and one end of the worm 400 away from the second gear 48 is rotatably connected to the inner wall of the connecting chamber 47, and the worm 400 is meshed with a worm wheel 401, and a rotating rod 402 is fixed to the top of the worm wheel 401. The self-adjusting component 4 also includes a reset member 49. When the flood suddenly rises, the movable plate 41 moves in the piston groove 40, driving the fixed rod 42 to move right, and the inner wall of the arc-shaped slide groove 46 abuts against the surface of the resistance rod 45. The resistance rod 45 moves along the arc-shaped slide groove 46, driving the first gear 44 to rotate, thereby driving the second gear 48, the worm 400, the worm wheel 401, and the rotating rod 402 to rotate. At this time, the volute spring 491 is wound, and the baffle 3 is raised through the thread, thereby realizing self-adjustment of the height to avoid sudden flood rise and flood leakage.

[0022] The reset member 49 includes a fixing ring 490, which is fixed to the top of the inner wall of the connecting chamber 47. A volute spring 491 is fixed to the inner side of the fixing ring 490. One end of the volute spring 491 away from the fixing ring 490 is fixed to the surface of the rotating rod 402. When the water level drops, the water pressure drops, and the volute spring 491 is released, driving the rotating rod 402, the worm wheel 401, the worm 400, and the gear two 48 to drive the gear one 44 to reverse, and the abutment rod 45 abuts against the arc-shaped slide groove 46, so that the fixing rod 42 drives the movable plate 41 to return to its position and wait for the next use.

[0023] The surface of the rotating rod 402 is provided with a thread, and the top of the rotating rod 402 passes through the baffle 3, and the thread of the rotating rod 402 is threadedly connected to the baffle 3, so that the baffle 3 can be driven to rise or fall when the rotating rod 402 rotates. The piston groove 40 and the surface of the flood control dike 1 are provided with air outlets, and when the piston of the movable plate 41 moves, the air in the piston groove 40 can be discharged through the air outlet holes. The end of the resistance rod 45 away from the gear 1 44 extends into the arc-shaped slide groove 46, and the surface of the resistance rod 45 resists against the inner wall of the arc-shaped slide groove 46. When the fixed rod 42 moves, the gear 1 44 is driven to rotate through the resistance rod 45 and the arc-shaped slide groove 46. The diameter of the gear 1 44 is larger than that of the gear 2 48, so that the gear 1 44 can be rotated, so that the rotation speed of the gear 2 48 is increased, and the lifting height of the baffle 3 is increased.

[0024] When a flood suddenly rises, the water pressure of the flood increases. Water pressure refers to the pressure exerted by water at a point on the surrounding environment of that point. When the flood suddenly rises, the flow rate increases and the water depth becomes deeper, resulting in an increase in water pressure. At this time, the movable plate 41 moves in the piston groove 40, so that the movable plate 41 drives the fixed rod 42 to move right. At this time, the inner wall of the arc-shaped slide groove 46 abuts against the surface of the resistance rod 45, so that the resistance rod 45 moves along the arc-shaped slide groove 46, thereby driving the gear 1 44 to rotate, thereby driving the gear 2 48 and the worm 400 to rotate, thereby driving the worm wheel 401 to rotate, and at this time the volute spring 491 is wound up, and at the same time drives the rotating rod 402 By rotating, the baffle plate 3 rises through the thread, thereby realizing self-adjusting height, avoiding sudden flooding and causing flood leakage. When the water level drops, the water pressure drops, and the volute spring 491 is released, driving the rotating rod 402 to reverse, thereby driving the worm wheel 401 and the worm 400 to reverse, and the reversed gear 2 48 drives the gear 1 44 to reverse, and the abutment rod 45 abuts against the arc-shaped slide groove 46, so that the fixed rod 42 drives the movable plate 41 to return to its position and wait for the next use. The air outlet hole can be set when the piston of the movable plate 41 moves, and the air in the piston groove 40 can be discharged through the air outlet hole, thereby avoiding the phenomenon that the movable plate 41 cannot move.

[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
