For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1-4 As shown, the utility model proposes an anti-seepage and water-stopping structure for use in water conservancy and hydropower projects, including flood control sandbags arranged on the surface of a dam 1 for anti-seepage and water-stopping.

[0027] In this embodiment, the anti-seepage and water-stopping structure further includes a flood control sandbag pressing mechanism 2 for pressing the flood control sandbags in both directions. Figure 3 The flood control sandbag pressing mechanism 2 includes a base rod 21, a bearing seat 22, a screw shaft 23, a pressing plate 24 and a motor 25. A pair of base rods 21 are provided, and the top of the base rod 21 is fixedly connected to the dam 1, and the bottom is inserted into the riverbed for fixing. Two pairs of bearing seats 22 are provided, and the bearing seats 22 at the same level and the bearing seats 22 and the adjacent base rods 21 are fixedly connected by connecting rods 211, so that the base rod 21 and the bearing seat 22 are maintained as an integral structure. A pair of screw shafts 23, pressing plates 24 and motors 25 are provided, and both ends of each screw shaft 23 are rotatably connected to the corresponding single bearing seat 22, and the two screw shafts 23 are respectively screwed with a single pressing plate 24. In addition, the two ends of the pressing plate 24 are respectively movably connected with the corresponding base rod 21, so that the pressing plate 24 can move along the base rod 21. The two bearing seats 22 located above are fixedly connected with a motor 25, and the output shaft of the motor 25 is fixedly connected to the top of the corresponding screw shaft 23. When the motor 25 is working, its output shaft drives the screw shaft 23 to rotate, thereby driving the single pressing plate 24 to move up and down along the base rod 21 to compact the flood control sandbag.

[0028] Furthermore, the anti-seepage and water-stopping structure also includes a pressing and guiding mechanism 3 for guiding the filling of the flood control sandbags and pressing the flood control sandbags on the upper side. Figure 4The clamping and guiding mechanism 3 includes a guiding platen 31, an arc-shaped connecting rod 32 and a cylinder 33. The guiding platen 31 is divided into three parts, and the three parts are fixedly connected as a whole by the arc-shaped connecting rod 32. A rotating shaft 311 is fixedly connected between the two bearing seats 22 located below, and the rotating shaft 311 is rotatably connected to the guiding platen 31. The cylinder 33 is fixed to the top of the dam 1, and the end of the piston rod of the cylinder 33 is fixedly connected to a shaft ring 331. The connecting sleeve rod 312 is fixedly connected to one side of the top of the guiding platen 31, and the connecting sleeve rod 312 is movably sleeved with the shaft ring 331. That is, the guiding platen 31 can be driven to rotate by the extension and contraction of the piston rod of the cylinder 33.

[0029] The working principle of this embodiment is: by adding flood prevention sandbags at the dam 1 and compacting the sandbags through the flood prevention sandbag compacting mechanism 2 and the compacting and guiding mechanism 3 to make them fit more tightly, the dam 1 can be effectively protected from seepage and water stopping; in addition, through the rotatable design of the guide pressure plate 31, the sandbags can be guided and prevented from falling out during the process of filling the sandbags, and the sandbags can be compacted at the end of filling.

[0030] Specifically, refer to Figure 3 One of the motors 25 works to drive the corresponding screw shaft 23 to rotate, and the screw shaft 23 drives the single pressing plate 24 below to move down to the bottom to support the flood control sandbag. The other motor 25 works to move the single pressing plate 24 above to the top by the same principle. Then, the piston rod of the cylinder 33 extends, and the guide pressing plate 31 is moved as shown in the figure through the cooperation of the shaft ring 331 and the connecting sleeve rod 312. Figure 2 As shown, the guide plate 31 is rotated to open a V-shaped gap, and the flood control sandbags are loaded through the gap to be attached to the surface of the dam 1 to prevent seepage and stop water. After the sandbags are loaded, the upper pressure plate 24 moves downward under the action of the motor 25 to press the sandbags, so that the sandbags are in closer contact with each other to enhance their waterproof effect. In this process, since the guide pressure plate 31 is inclined, it can provide guidance for the loading of the sandbags, so that they can reach the correct position and avoid falling out. After the loading is completed, the piston rod of the cylinder 33 contracts, driving the guide pressure plate 31 as shown in FIG. Figure 1 The rotation reset shown can compress the sandbag from the upper side to further increase its compactness and prevent the sandbag from detaching from the embankment 1.

[0031] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
