[0019] like Figures 1 to 4As shown, the utility model discloses a stable channel flood control device for channel repair and prevention engineering, including a frame 1 and a gate 2, two sides of the frame 1 are provided with slide grooves 101, two ends of the gate 2 are coupled to the slide grooves 101 and can form a sliding fit between the two, the center position of the frame 1 is connected to a lead screw 3 for rotation in the vertical direction, the gate 2 is sleeved on the lead screw 3 and can form a threaded fit between the two, the top of the lead screw 3 is connected to a hand wheel 4, two sides of the gate 2 are provided with mounting frames 5, the mounting frames 5 are connected to a protective plate 6, the protective plate 6 moves with the movement of the gate 2, and when the gate is opened, the protective plate 6 will pile up The debris accumulated in front of the gate 2 is lifted upward to reduce the movement of the debris toward the gate 2. After the gate 2 is closed, the protective plates 6 on both sides can sink to the bottom of the water, so the debris accumulated in front of the gate 2 will be above the protective plates 6. When the gate 2 is opened, as the protective plates 6 move upward with the gate 2, the debris accumulated in front of the gate 2 can be lifted to reduce the movement of the debris in front of the gate 2 toward the closed part of the gate 2, thereby preventing the debris accumulated in front of the gate 2 from blocking the gate 2 or causing blockage of the river flow outlet after the gate is opened, thereby ensuring the overall flood control effect and improving the stability of use.
[0020] In this embodiment, the specific structure of the mounting frame 5 includes a crossbeam 51 and a longitudinal beam 52. The crossbeam 51 is fixed to the surface of the gate 2, and the longitudinal beam 52 is vertically fixed to both sides of the crossbeam 51. One side end of the protective plate 6 is rotatably connected to the crossbeam 51, and a locking device is provided at the end of the crossbeam 51 away from the longitudinal beam 52. The locking device is used to fix the protective plate 6 to the gate. By setting a rotatable connection between the protective plate 6 and the crossbeam 51, the protective plate 6 can be flipped 90°. Therefore, the protective plate 6 can be flipped toward the gate to achieve folding. This can reduce the space occupied by flood control equipment during storage and transportation, so as to facilitate the storage and transportation of flood control equipment. The crossbeam 51 can support the protective plate 6 to ensure the stability of the protective plate 6 when lifting debris. After the protective plate 6 is folded, the locking device locks the protective plate 6, which can improve the stability of the protective plate 6 after folding.
[0021] In this embodiment, the specific structure of the locking device includes a guide block 71, which is provided with an inclined guide side wall 711. The guide block 71 is located on a side close to the gate and is provided with a locking hole 712. The protective plate 6 is located on a side away from the crossbeam 51 and is internally provided with a mounting groove 61 with a notch facing the guide side wall 711. A slidable locking rod 72 is provided in the mounting groove 61. The outer periphery of the locking rod 72 is provided with a flange 721 and a spring 73 sleeved on the outer periphery of the locking rod 72. One end of the spring 73 is fixed to the flange 721, and the other end is fixed to the bottom of the mounting groove 61. The locking rod 72 is located on the side facing the guide side wall 711 and can be coupled with the guide side wall 711, and can slide into the locking hole 712 along the guide side wall 711 to form a limit fit between the two. When needed When the protective plate 6 is to be folded, the protective plate 6 is flipped toward the gate plate so that the locking rod 72 can contact the guide side wall 711. As the protective plate 6 is flipped toward the gate plate, the locking rod 72 can be pushed toward the installation groove 61 under the action of the guide side wall 711 to compress the spring 73. When the locking rod 72 moves to a position opposite to the locking hole 712, the compressed spring 73 can push the locking rod 72 into the locking hole 712 to form a limit fit between the two, thereby completing the locking of the protective plate 6. Similarly, when the flood control equipment is put into the channel for use, the locking rod 72 can be pulled out from the locking hole 712, and the protective plate 6 can be turned in an open state by flipping the protective plate 6 in a direction away from the gate plate.
[0022] In this embodiment, in order to facilitate the pulling out of the locking rod 72 from the locking hole 712, a fixing sleeve 8 is further fixed on the outer periphery of the locking rod 72. The fixing sleeve 8 is located on the outer side of the mounting groove 61. A push rod 9 extending outward is fixed on the fixing sleeve 8. The setting of the push rod 9 can provide a force point to facilitate pulling the locking rod 72.
[0023] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
