[0021] 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.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A flood control wall for water conservancy projects includes a flood control base plate 1. A lifting mechanism is provided on the surface of the flood control base plate 1. The lifting mechanism includes a bidirectional lead screw 2, which is rotatably connected to the inner surface of the flood control base plate 1. A square nut 21 is threaded onto the surface of the bidirectional lead screw 2. A support rod 22 is rotatably connected to the surface of the square nut 21. A heightening plate 23 is slidably connected to the surface of the flood control base plate 1. The end of the support rod 22 away from the square nut 21 is rotatably connected to the bottom of the heightening plate 23. A motor 24 is fixedly connected to the surface of the flood control base plate 1. A first conical nut 25 is fixedly connected to the output shaft of the motor 24. A second conical nut 26 is fixedly connected to the surface of the bidirectional lead screw 2. This lifting mechanism can change the protection height of the flood control wall, improve the environmental adaptability of the flood control wall, and enhance the flood control capacity of the flood control wall during the rainy season.

[0024] Furthermore, a seepage-proof mechanism is provided at the bottom of the flood control base slab 1. The seepage-proof mechanism includes a fixing plate 3, which is fixedly connected to the bottom of the flood control base slab 1. A connecting rod 31 is fixedly connected to the bottom of the fixing plate 3. A seepage-proof plate 32 is inserted into the surface of the fixing plate 3. A connecting horizontal plate 33 is fixedly connected to the top of the seepage-proof plate 32. There may be gaps at the bottom of the flood control base slab 1, which may cause a small amount of water to seep out from the bottom of the flood control base slab 1. The two sets of seepage-proof plates 32 of this seepage-proof mechanism, together with the connecting rod 31, are inserted into the soil at the bottom of the flood control base slab 1, which reduces the amount of water seeping from the top of the flood control base slab 1 and improves the effectiveness of the flood control wall.

[0025] Furthermore, a guide groove is provided on the surface of the flood control base plate 1. The heightening plate 23 slides and rises and falls on the guide groove of the flood control base plate 1. The heightening plate 23, together with the flood control base plate 1, realizes the change of the overall height of the flood control wall. The two-way screw 2 is rotatably connected to the bottom of the guide groove of the flood control base plate 1. The two-way screw 2 restricts the position of the square nut 21 in the guide groove of the flood control base plate 1.

[0026] Furthermore, the square nut 21 is in contact with the bottom of the guide groove of the flood control base plate 1. The bidirectional screw 2 drives the square nut 21 to slide at the bottom of the guide groove of the flood control base plate 1 by rotation. There are two sets of square nuts 21, and the sliding directions of the two sets of square nuts 21 are opposite. The square nut 21 drives the heightening plate 23 to slide and rise on the guide groove of the flood control base plate 1 through the support rod 22. The square nut 21 supports the heightening plate 23 through the support rod 22, ensuring the relative positional relationship between the flood control base plate 1 and the heightening plate 23.

[0027] Furthermore, the first conical nut 25 and the second conical nut 26 mesh with each other. The motor 24 drives the first conical nut 25 to rotate through the output shaft. The first conical nut 25 drives the bidirectional lead screw 2 to rotate on the guide groove of the flood control base plate 1 through the second conical nut 26. This eliminates the need for manual adjustment of the height of the raised plate 23, making the height adjustment of the raised plate 23 convenient. In addition, a water outlet is provided on the bottom guide groove of the flood control base plate 1. A sealing gasket is used to seal the guide groove of the flood control base plate 1 and the raised plate 23. Water that penetrates into the guide groove of the flood control base plate 1 through the raised plate 23 will be discharged through the water outlet at the bottom of the flood control base plate 1.

[0028] Furthermore, there are two sets of fixing plates 3, and the two sets of fixing plates 3 are symmetrically located inside the bottom of the flood control base plate 1. There are two sets of plug rods 31 on each set of fixing plates 3. The bottom of the plug rods 31 and the impermeable plate 32 are in the shape of an isosceles triangle, so that the plug rods 31 and the impermeable plate 32 can be easily inserted into the soil.

[0029] Furthermore, the surface of the fixing plate 3 is provided with insertion holes, and the seepage-proof plate 32 is inserted into the insertion holes of the fixing plate 3. The two sides of the seepage-proof plate 32 are in contact with the surface of the insertion rod 31. The connecting horizontal plate 33 and the seepage-proof plate 32 are perpendicular to each other. The insertion rod 31 and the seepage-proof plate 32 cover the bottom of the flood control base plate 1 in the soil, reducing the amount of water seepage at the bottom of the flood control wall.

[0030] Working principle: The output shaft of motor 24 drives the first conical nut 25 to rotate. Motor 24 drives the bidirectional lead screw 2 to rotate on the guide groove of the flood control base plate 1 through the second conical nut 26. The bidirectional lead screw 2 drives two sets of square nuts 21 to slide on the guide groove of the flood control base plate 1 through rotation. The square nuts 21 drive the raising plate 23 to rise and fall on the surface of the flood control base plate 1 through the support rod 22, thereby changing the protection height of the flood control wall, improving the environmental applicability of the flood control wall, and enhancing the flood control capacity of the flood control wall in the rainy season.

[0031] The flood control base plate 1 at the bottom of the fixed plate 3 is inserted into the soil, and the seepage-proof plate 32 is inserted into the insertion hole of the fixed plate 3. The seepage-proof plate 32 is driven into the soil at the bottom of the fixed plate 3 by the connecting horizontal plate 33, so that the seepage-proof plate 32 and the insertion rod 31 are in contact and connected together. The two sets of seepage-proof plates 32 and insertion rods 31 cover the bottom of the flood control base plate 1 in the soil, reducing the seepage at the bottom of the flood control wall and improving the use effect of the flood control wall.
