[0001] This utility model relates to the field of water conservancy planning and design technology, specifically to a water conservancy planning, design and construction cofferdam device. Background Technology

[0002] In the planning, design, and construction of water conservancy projects, cofferdams play a crucial role. A cofferdam is a temporary water-retaining structure primarily used to protect construction pits, preventing water and soil from entering the construction site and ensuring the effective construction of water conservancy facilities. It is typically built in hydraulic engineering projects. While some projects utilize cofferdams as permanent structures, most are dismantled after construction. Cofferdams can be classified by material into earth-rock cofferdams, concrete cofferdams, straw-soil cofferdams, wooden cage cofferdams, bamboo cage cofferdams, and steel sheet pile lattice cofferdams.

[0003] Most existing cofferdam devices are integral units, which means they require a lot of space to transport, making them inconvenient and reducing transport efficiency. In addition, some existing devices require diagonal supports for support, but these external diagonal supports are inconvenient to install and remove, further reducing the installation efficiency of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, a cofferdam device for water conservancy planning, design, and construction includes a baffle plate 1. A reinforcing rib 2 is fixedly connected to one side of the baffle plate 1, increasing its strength and effectively reducing deformation and bending. Mounting frames 3 are fixedly connected to two points on both sides of the baffle plate 1. A movable frame 4 is mounted on one side of the mounting frame 3, and a positioning groove 5 is formed on one side of the movable frame 4. The inner cavity of the positioning groove 5 and the cross-sectional shape of one side of the mounting frame 3 are both T-shaped. The surface of the mounting frame 3 slides against the inner wall of the positioning groove 5, allowing the movable frame 4 to be shaped accordingly. The limit switch prevents the movable frame 4 from easily detaching from the surface of the mounting frame 3 when sliding, effectively improving the stability of the movable frame 4. A movable plate 6 is rotatably connected to the inner cavity of the movable frame 4. Positioning holes 7 are provided on the surface of the movable plate 6, facilitating the fixation of the device through the cooperation of the movable plate 6 and the positioning holes 7, thus making the device more stable during use. A fixing frame 8 is fixedly connected to the surface of the blocking plate 1. Two blocking rods 9 are fixedly connected to each other on one side of the fixing frame 8. The surfaces of the blocking rods 9 are movably connected to the surface of the movable plate 6. Under this action, the two blocking rods 9 can be used to... When the movable plate 6 is stored, it will not easily rotate. When the movable plate 6 needs to be unfolded, the movable frame 4 can be slid to the other side by cooperating with the mounting bracket 3 and the positioning groove 5. Then, the position of the movable frame 4 is not aligned with the blocking rod 9, and the movable plate 6 can be rotated. After rotation, the movable frame 4 is moved back to its original position, which facilitates the installation of the device. With the cooperation of the lower blocking rod 9, the movable plate 6 can be limited, so that the movable plate 6 will not easily shift its position, making the device more stable when fixed. A magnet 13 is embedded on one side of the fixing bracket 8. The movable frame 4 is made of iron. The magnet block 13 works in conjunction with the movable frame 4. Under this action, the movable frame 4 can be limited by the cooperation of the movable frame 4 and the magnet block 13, so that the movable frame 4 will not easily have a large positional deviation, effectively improving the stability of the movable frame 4 during use. A support shell 10 is fixedly connected to one side of the blocking plate 1. A positioning mechanism 11 is installed in the inner cavity of the support shell 10. With the cooperation of the positioning mechanism 11, the blocking plate 1 can be inclinedly supported, so that the device can be more stable after installation, further improving the applicability of the device.

[0022] The positioning mechanism 11 includes a movable rod 111 that slides within the inner cavity of the support shell 10. A support rod 112 is fixedly connected to the surface of the movable rod 111. The surface of the support rod 112 is slidably connected to the inner wall of the support shell 10. A blocking groove 113 is provided on one side of the inner cavity of the support shell 10. The blocking groove 113 has an inclined structure design. The inner wall of the blocking groove 113 is slidably connected to the surface of the movable rod 111. Under this action, the movable rod 111 can be embedded into the blocking groove 113 at a suitable position according to the ground conditions, thereby limiting the support rod 112. This allows the support rod 112 to provide oblique support for the blocking plate 1, effectively improving the stability of the device. Qualitatively, a locking groove 12 is provided at the bottom of the inner cavity of the support shell 10. The inner wall of the locking groove 12 is slidably connected to the surface of the support rod 112. Under this action, the support rod 112 can be limited by the cooperation of the movable rod 111 and the locking groove 12, so that it will not easily detach from the inside of the support shell 10, effectively improving the stability of the support rod 112. A movable frame 14 is fixedly connected to one side of the support rod 112. The movable frame 14 is used in conjunction with the support rod 112. Under this action, after the support rod 112 is embedded in the inside of the support shell 10, the movable frame 14 facilitates the movement of the support rod 112 by the staff.

[0023] Working principle: First, when the device needs to be installed, the operator pushes the movable frame 4 to prevent the movable plate 6 from contacting the blocking rod 9. Then, the movable plate 6 is rotated 90 degrees, and then the movable frame 4 is used to move the movable plate 6 back to its original position. The blocking rod 9 limits the movable plate 6. Then, the operator fixes the device with the help of the positioning hole 7. This method reduces the space required for the device during transportation, making it convenient for transport. Then, with the help of the movable frame 14, the support rod 112 is taken out from the inside of the locking groove 12. Then, the support rod 112 is rotated and its position is moved. The movable rod 111 is inserted into the blocking groove 113 in the appropriate position according to the required support position. Then, the other end of the support rod 112 is fixed. The support rod 112 provides diagonal support for the blocking plate 1, which effectively improves the stability of the device during use.
