However, the seismic resistant structure of the water conservancy dam used in the prior art cannot form a fixed combination with the dam body with high stability, and the dam body needs to be excavated destructively, and cannot achieve good buffering convection and stepped flow slowing functions in the case of earthquake waves. Therefore, a seismic resistant structure of a water conservancy dam is designed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0032] like Figure 1-Figure 9 As shown, a hydraulic dam earthquake-resistant structure provided in this embodiment includes a dam body 1, and a dam top surface 5 with multiple groups of reinforcement members arranged on the top of the dam body 1;

[0033] The reinforcement member is inserted through the dam top 5 into the dam body 1, and cement slurry is injected into the reinforcement member into the dam body 1, so that the dam body 1 is solidified in layers to form a reinforcement layer 2;

[0034] Pull back the reinforcing member, and adjust the reinforcing deformable member engaged on the outer side of the reinforcing member so that it deforms and is pressed against the bottom of the reinforcing layer 2 for reinforcement;

[0035] A hollow step 6 is provided on the upstream slope of the dam body 1, and a filter screen plate 4 is provided on the top of the hollow step 6 and on the side facing the water flow;

[0036] The outer side of the filter screen plate 4 facing the water flow is hinged with a hinged door group that is expanded outwards.

[0037] The general working principle is as follows: the earthquake surges to the upstream slope of the dam body 1, enters the hollow step 6 through the top filter plate 4 of the hollow step 6, collides with the power generation roller 3 in the hollow step to form an internal vortex, and automatically pushes open the hinged door 8, and the water flowing out of the hinged door 8 hits the earthquake surge in the opposite direction. The design of the hinged door 8 and the impact of the reverse water flow form a double obstacle, achieving the effect of controlling water with water and reducing earthquake surges; insert the hollow reinforcement member into the dam body 1, and inject cement slurry into the dam body 1 through the reinforcement member, so that the dam body 1 is layered and solidified to form a reinforcement layer 2, pull back the reinforcement member, and adjust the reinforcement deformation member meshing on its outer side to deform and hold it at the bottom of each reinforcement layer 2, so that the reinforcement skeleton and the dam are integrated, and the technical effect of implementing efficient reinforcement without excavating the dam body 1 is achieved.

[0038] In this embodiment, the reinforcement member includes a reinforcement screw 7, an external gear 15, a hexagonal nut 10 and a slurry outlet hole 14;

[0039] The reinforcing screw rod 7 is a hollow structure, and an external gear 15 is installed on the top of the reinforcing screw rod 7, and a hexagonal nut 10 is integrally formed on the top of the external gear 15;

[0040] The rod body of the reinforcing screw rod 7 is provided with slurry outlet holes 14 at equal intervals.

[0041] Local working principle: multiple groups of hollow reinforcement screws 7 are inserted into the dam body 1 through the dam top surface 5, and cement slurry is injected into the hollow reinforcement screws 7 in layers. The cement slurry enters the dam body 1 through the slurry outlet holes 14 on the rod body and diffuses along the pores to form a reinforcement layer 2, so that the dam body 1 is solidified in layers.

[0042] In this embodiment, the reinforcing deformable member includes a lifting adjustment nut 11, a reinforcing sheet 12, and a rubber layer 13;

[0043] The outer side of the reinforcing screw rod 7 is meshed with multiple sets of lifting and adjusting nuts 11 , and the top ring portion of the lifting and adjusting nuts 11 is integrally formed with a reinforcing sheet 12 , and the two sides and the top of the reinforcing sheet 12 are bonded with a rubber layer 13 .

[0044] Local working principle: The lifting and adjusting nut 11 is sleeved on the outside of the reinforcement screw 7 and adjusted to a certain distance below the slurry outlet hole 14. The reinforcement layer 2 that flows out through the slurry outlet hole 14 and solidifies in the dam body 1 contacts the top of the reinforcement sheet 12. The reinforcement screw 7 is driven to rotate by rotating the hexagonal nut 10. The reinforcement screw 7 simultaneously drives the lifting and adjusting nut 11 to rotate. A relatively large friction force is formed between the reinforcement sheet 12 and the reinforcement layer 2. The reinforcement screw 7 and the lifting and adjusting nut 11 have a speed difference, so that the lifting and adjusting nut 11 moves upward along the reinforcement screw 7, thereby pressing the reinforcement sheet 12 to deform and pulling the rubber layer 13 to rupture, so that the reinforcement sheet 12 is flatly attached to the bottom of the reinforcement layer 2, thereby achieving the technical effect of reinforcement.

[0045] In this embodiment, the hinged door assembly includes a hinged door 8 and a limit block 9;

[0046] A hinged door 8 is provided on the side of the hollow step 6 facing the water flow, and a limiting block 9 is integrally formed on the hollow step 6 at the bottom of the hinged door 8 , and the hinged door 8 is in contact with the limiting block 9 .

[0047] Local working principle: The hinged door 8 is limited by the limit block 9, and the water flows into the hollow step 6 through the filter screen plate 4, collides with the power generation roller 3 in the hollow step to form an internal vortex, and automatically pushes open the hinged door 8, and the water flowing out of the hinged door 8 hits the earthquake wave in the opposite direction.

[0048] In this embodiment, the top of the hollow step 6 is an inwardly inclined structure.

[0049] Local working principle: By designing the top of the hollow step 6 to be inclined inward, the function of efficiently storing water and guiding the water flow to enter through the filter screen plate 4 on the top of the hollow step 6 is achieved. Because the top of the hollow step 6 is inclined inward, the end of the hollow step 6 is a raised structure to increase the flow suppression effect. In addition, the present invention designs multiple groups of hollow steps 6 to form a stepped technical effect of preventing earthquake waves.

[0050] The hollow step 6 is fixed on the upstream dam surface of the dam body 1 by means of screw fixing.

[0051] In this embodiment, a power generation roller 3 is also arranged inside the hollow step 6 via a bearing.

[0052] Local working principle: The kinetic energy generated when the power generation roller 3 rotates is designed to be transmitted to the energy storage battery connected to the insulation plate 3 for storage and use. The energy storage method and the method of converting kinetic energy into electrical energy are prior art and will not be described again.

[0053] The above description is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and concepts of the present invention within the scope disclosed by the present invention, which belong to the protection scope of the present invention.
