Description

Technical Field

[0001] The present application relates to the technical field of dam body earthquake resistance, and specifically to a dam body earthquake resistance structure with soft and hard rock filling. Background Art

[0002] Dam body soft and hard rock filling refers to the use of soft and hard rocks for filling during the dam construction process. The rock materials are eroded, which will continuously carry away the fine particles on the surface of the dam body, causing the dam body to gradually lose its protective layer, increasing the speed and depth of erosion. Long-term erosion may cause the dam body to become partially or completely thinner, reducing its bearing capacity.

[0003] The existing patent (publication number: CN220725003U) discloses a dam body soft and hard rock filling earthquake-resistant structure, including a dam body, the inner wall of the dam body is wrapped with columns, the outer ends of the columns are fixedly connected to a plurality of triangular brackets, the triangular brackets are inside the dam body, the outer ends of the dam body are provided with a reinforcement mechanism, and the other side of the dam body is provided with a stabilizing mechanism. The utility model uses the triangular brackets inside the dam body to make the structure lightweight, improve the structural strength of itself and the dam body, thereby improving the earthquake resistance of the dam body, through the cooperation of nuts and threaded rods, the steel plate and the side protective plate are firmly fixed on the surface of the dam body, and the water flow impact resistance of the dam body is improved, the upper protective plate is fixed to the column by a connecting piece, so that the structure forms a whole, and the structural strength of the dam body is improved, and the reinforcement mechanism can not only reduce the impact of water flow on the upstream slope, but also reduce the situation where external rainwater penetrates into the dam body through the downstream slope, thereby improving the service life of the dam body.

[0004] The upper protective plate is fixed to the column by the connecting parts, so that the structure forms an integral whole, and the structural strength of the dam body is improved. The reinforcement mechanism can not only reduce the impact of water flow on the upstream slope, but also reduce the infiltration of external rainwater into the dam body through the downstream slope, thereby improving the service life of the dam body. However, it is found in the process of use that although the steel plate and the side protective plate are firmly fixed on the surface of the dam body, thereby improving the dam body's ability to resist water flow impact, the continuous beating of the water flow can easily cause the steel plate to be subjected to hard collision, and the dam body is frequently vibrated through the transmission of force, resulting in redistribution of stress inside the dam body, which may cause cracks at the junction of soft and hard rocks or in soft rock layers. These cracks not only affect the integrity of the dam body, but may also become infiltration channels for water flow, aggravating erosion and damage to the dam body. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a dam body soft and hard rock fill earthquake-resistant structure, which has the advantages of buffering, energy absorption and power generation, and solves the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a dam body soft and hard rock filling earthquake-resistant structure, comprising a dam body, a notch is opened inside the right bottom end of the dam body, a fixed rib is rotatably connected between the front and rear inner walls of the notch, a buffer plate is fixedly connected to the outer surface of the fixed rib, the top end of the buffer plate is in a right-turned curling shape, and a plurality of dampers arranged at equal distances are provided between the buffer plate and the bottom end of the dam body at an angle;

[0007] A plurality of energy absorbing components are provided between the dam body and the buffer plate;

[0008] Each of the energy absorbing components comprises two springs, two fixed plates, a sliding rod, a moving sleeve and a connecting rod;

[0009] A plurality of arc-shaped incomplete tooth rings are fixedly connected to one side of the buffer plate close to the dam body, a power generation shaft is provided on the right side of the dam body, and a plurality of equally spaced gears are rotatably connected to the outer surface of the power generation shaft via a one-way bearing, and each of the arc-shaped incomplete tooth rings is meshed with a gear close to it.

[0010] Through the above scheme, the top of the buffer plate is set to be curled to the right, which can effectively prevent the water from hitting the buffer plate and rushing to the surface of the dam body through inertia during the tide, effectively avoiding the scouring of the dam body. When the buffer plate is washed, the dynamic potential energy can squeeze the buffer plate to flip to the left, and absorb energy through the setting of the buffer component. In conjunction with the damper, the dynamic potential energy is effectively buffered to avoid the transmission of force and improve the protection performance of the dam body. The arc-shaped incomplete gear can drive the gear and the power generation shaft to rotate when the buffer plate flips. In conjunction with the external power generation device, the tidal potential energy can be used to generate electricity, effectively improving the overall practicality.

[0011] Furthermore, the bottom end of each damper is hinged to the dam body, and the top end of each damper is hinged to the buffer plate.

[0012] Through the above solution and the provision of the damper, the purpose of buffering can be achieved.

[0013] Furthermore, the buffer plate is made of corrosion-resistant material, and a folding protective plate is fixedly connected between the bottom end of the dam body and the top end of the buffer plate.

[0014] Through the above scheme, by setting the buffer plate to be corrosion-resistant material, the service life of the buffer plate can be effectively improved, and the setting of the folding protective plate can prevent people from falling between the dam body and the folding protective plate.

[0015] Furthermore, each of the fixed plates is fixedly connected to the dam body, both ends of each sliding rod are respectively fixedly connected to the fixed plates adjacent to it, each of the movable sleeves is slidably sleeved to the sliding rod adjacent to it, the bottom end of each connecting rod is hinged to the movable sleeve adjacent to it, the top end of each connecting rod is hinged to the buffer plate, and both ends of each spring are respectively fixedly connected to the fixed plate and buffer sleeve adjacent to it.

[0016] Through the above scheme, the purpose of energy absorption can be achieved through the arrangement of the connecting rod, the buffer sleeve and the spring.

[0017] Furthermore, a plurality of brackets arranged at equal distances are fixedly connected to the right side surface of the dam body, and the power generation shaft is rotatably connected to the plurality of brackets.

[0018] Through the above scheme and the setting of the bracket, the purpose of supporting the power generation shaft can be achieved.

[0019] Furthermore, both ends of the power generation shaft are connected to external generator devices.

[0020] Through the above scheme, by setting the power generation shaft, the rotational kinetic energy can be converted into electrical energy.

[0021] Furthermore, each of the springs is sleeved with a sliding rod adjacent to it.

[0022] Through the above solution, the spring is prevented from bending during the stretching or compression process by the sleeve connection between the spring and the slide rod.

[0023] Furthermore, when each of the gears rotates clockwise, the one-way bearing is in a locked state, and when each of the gears rotates counterclockwise, the one-way bearing is in an active state.

[0024] Through the above solution, by setting the one-way bearing, it is possible to avoid the gear driving the generator shaft to intermittently reciprocate and reverse.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] The soft and hard rock filled earthquake-resistant structure of the dam body can effectively prevent the water from hitting the buffer plate and rushing to the surface of the dam body through inertia during the tide period by setting the top of the buffer plate to be turned to the right, thereby effectively preventing the dam body from being washed away. When the buffer plate is washed away, the dynamic potential energy can squeeze the buffer plate to turn to the left, and absorb energy through the setting of the buffer component, and cooperate with the damper to effectively buffer the dynamic potential energy, avoid the transmission of force, and improve the protection performance of the dam body. The arc-shaped incomplete gear can drive the gear and the power generation shaft to rotate when the buffer plate turns over. In cooperation with the external power generation device, the tidal potential energy can be used to generate electricity, effectively improving the overall practicality.

A power generation shaft 8 is provided on the right side of the dam body 1. The outer surface of the power generation shaft 8 is rotatably connected to a plurality of equally spaced gears 9 through a one-way bearing. When each gear 9 rotates clockwise, the one-way bearing is in a locked state. When each gear 9 rotates counterclockwise, the one-way bearing is in an active state.

[0039] In the present embodiment, a dam body 1 is a soft and hard rock filled earthquake-resistant structure.
