Technical Field

[0001] The utility model relates to the technical field of hydraulic dams, in particular to a multi-stage water retaining hydraulic dam. Background Art

[0002] A hydraulic dam refers to a hydraulic concrete lifting dam, which is a relatively simple movable dam technology in water conservancy technology. When in use, the hydraulic dam is driven by the hydraulic system to rotate the hydraulic dam to achieve the purpose of raising the dam to block water and lowering the dam to discharge floodwater. In the prior art, there is a hydraulic dam with a multi-level water-blocking effect. During the working process, the height of the hydraulic dam is changed by the rotation of the hydraulic dam to achieve the multi-level water-blocking effect of the hydraulic dam. During installation, sometimes the support mounting seat of the hydraulic cylinder is deviated due to the staff's mistake, which causes the hydraulic cylinder to push the dam surface steel plate and the adjacent dam surface steel plate to be misaligned, so that the staff needs to reinstall the support mounting seat of the hydraulic cylinder, and even the hydraulic dam cannot be used, resulting in economic losses.

[0003] Therefore, it is necessary to provide a new multi-stage water-retaining hydraulic dam to solve the above-mentioned technical problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0020] See also Figures 1 to 3 An embodiment of the utility model provides a multi-stage water-retaining hydraulic dam, which includes: a base 1, a dam surface steel plate 3, a multi-stage hydraulic cylinder 4 and an adjustment component 5.

[0021] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 A rotating shaft 2 is fixedly mounted on the base 1, and a rotatably connected dam surface steel plate 3 is sleeved on the rotating shaft 2. A multi-stage hydraulic cylinder 4 for supporting the dam surface steel plate 3 and an adjusting component 5 for adjusting the position of the multi-stage hydraulic cylinder 4 are installed on the base 1, and the adjusting component 5 includes a fixed plate 51, the fixed plate 51 is fixedly mounted on the base 1, and a mounting frame 52 is fixedly mounted on the fixed plate 51, a rotatably connected threaded rod 53 is mounted on the mounting frame 52, and a threaded bearing seat 55 is threadedly connected on the threaded rod 53, and a rotatably connected multi-stage hydraulic cylinder 4 is mounted on both sides of the upper surface of the threaded bearing seat 55, and the output end of the multi-stage hydraulic cylinder 4 is rotatably connected to the back side of the dam surface steel plate 3, and a knob 54 is fixedly mounted on the end of the threaded rod 53.

[0022] It should be noted that: when installing the multi-stage hydraulic cylinder 4 on the base 1, the fixing plate 51 is first fixed on the base 1 on the dam surface, and then the multi-stage hydraulic cylinder 4 is installed on the back of the dam surface steel plate 3 and the fixing plate 51, and the threaded bearing seat 55 is driven to adjust along the threaded rod 53 by rotating the knob 54, so as to adjust the installation position of the multi-stage hydraulic cylinder 4, so as to avoid the hidden danger of misalignment between the bottom installation of the multi-stage hydraulic cylinder 4 and the adjacent dam surface steel plate when the multi-stage hydraulic cylinder 4 pushes the dam surface steel plate due to installation errors of the staff;

[0023] Among them, the limiting rods 56 are fixedly installed on the mounting frames 52 on both sides of the threaded rod 53, and the limiting rods 56 pass through the through holes opened in the threaded bearing seat 55 and are slidably connected with the through holes, thereby improving the stability of the threaded bearing seat 55 when sliding along the threaded rod 53;

[0024] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 The front end surface of the dam surface steel plate 3 is provided with an arc surface 31, and a water guide component 6 is installed on the arc surface 31 of the dam surface steel plate 3, and the water guide component 6 includes a sleeve rod 61, and both ends of the sleeve rod 61 are fixedly installed with fixed brackets 62, and the fixed bracket 62 is fixedly installed on the dam surface steel plate 3, and the sleeve rod 61 is sleeved with a rotatably connected sleeve 63, and a plurality of annularly distributed arc blades 64 are fixedly embedded on the sleeve 63.

[0025] It should be noted that when the water in the reservoir is discharged from the curved surface 31 of the dam surface steel plate 3, the water drives the curved blades 64 on the sleeve 63 to rotate, so that the curved blades 64 drive the outflowing water parabola to increase its height, thereby avoiding the impact of the water on the regulating component 5.

[0026] The working principle of the multi-stage water-blocking hydraulic dam provided by the utility model is as follows:

[0027] When installing the multi-stage hydraulic cylinder 4 on the base 1, first fix the fixing plate 51 on the base 1 on the dam surface, and then install the multi-stage hydraulic cylinder 4 on the back of the dam surface steel plate 3 and the fixing plate 51, and drive the threaded bearing seat 55 to adjust along the threaded rod 53 by rotating the knob 54, so as to adjust the installation position of the multi-stage hydraulic cylinder 4, so as to avoid the hidden danger of deviation in the bottom installation of the multi-stage hydraulic cylinder 4 due to installation errors of the staff, thereby causing the multi-stage hydraulic cylinder 4 to push the dam surface steel plate and the adjacent dam surface steel plate. When the water in the reservoir is discharged from the curved surface 31 of the dam surface steel plate 3, the water drives the curved blade 64 on the sleeve 63 to rotate, so that the curved blade 64 drives the outflowing water parabola to increase in height, thereby avoiding the impact of the water on the adjustment component 5.
