Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, in particular to a reinforcement structure for a cofferdam of a water conservancy and hydropower engineering. Background Art

[0002] A cofferdam is a temporary retaining structure built for permanent water conservancy facilities in water conservancy project construction. Its function is to prevent water and soil from entering the construction site of the building so that drainage can be done in the cofferdam, foundation pits can be excavated, and buildings can be built. It is generally used in hydraulic structures. Except as part of a formal building, the cofferdam is generally dismantled after use. The height of the cofferdam is higher than the highest water level that may occur during the construction period.

[0003] The cofferdam reinforcement mechanisms in the prior art are mostly fixed structures, which cannot adjust the impact resistance and pressure resistance according to the actual force intensity, thus having a great impact on their actual use effect. After being dismantled, it is not easy to repeat and recycle them many times, which easily causes waste of resources. For this reason, we propose a reinforcement structure for the cofferdam of water conservancy and hydropower projects. Utility Model Content

[0004] The purpose of the utility model is to provide a reinforcement structure for cofferdams of water conservancy and hydropower projects, which has the advantage of adjusting the impact resistance and pressure resistance according to the actual force strength, and solves the problem that the impact resistance and pressure resistance cannot be adjusted according to the actual force strength, thereby having a great impact on its actual use effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reinforcement structure for a cofferdam of a water conservancy and hydropower project, comprising a connecting mechanism, wherein a plurality of angle fixing mechanisms are fixedly installed inside the connecting mechanism, and an adjustment mechanism is fixedly installed inside every two groups of angle fixing mechanisms, wherein the adjustment mechanism comprises a first mounting seat and a second mounting seat, wherein a screw is fixedly installed on one side of the first mounting seat, and an adjustment knob is threadedly connected to the surface of the screw;

[0006] A limiting rod is fixedly mounted on one side of the second mounting seat, and the limiting rod is slidably mounted inside the screw rod. A spring is fixedly mounted on one side of the second mounting seat.

[0007] As a preferred reinforcement structure for a water conservancy and hydropower project cofferdam of the utility model, the angle fixing mechanism includes a mounting block and a fixing bolt, a rotating block is rotatably mounted inside the mounting block, a connecting shaft is rotatably mounted inside the mounting block, threaded holes are provided on the surfaces of the mounting block and the connecting shaft, an assembly hole is provided inside the rotating block, and a plurality of limit strips are provided on the outer wall of the connecting shaft.

[0008] As a preferred reinforcement structure for a water conservancy and hydropower engineering cofferdam of the utility model, the connecting mechanism includes a mounting frame, a support seat, and pins, and a plurality of mounting holes are provided inside the mounting frame and the support seat.

[0009] As a preferred reinforcement structure for a water conservancy and hydropower engineering cofferdam of the utility model, a plurality of anti-slip grooves are provided on one side of the mounting frame and the supporting seat.

[0010] As a preferred reinforcement structure for a water conservancy and hydropower engineering cofferdam of the utility model, a plurality of weight-reducing grooves are provided inside the mounting frame.

[0011] As a preferred reinforcement structure for a water conservancy and hydropower engineering cofferdam of the utility model, the angle fixing mechanism also includes a first fixing pin, and a second fixing pin is threadedly connected to one side of the first fixing pin.

[0012] As a preferred reinforcement structure for a water conservancy and hydropower engineering cofferdam of the utility model, the outer wall of the adjusting knob is provided with anti-slip grooves.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model limits the contraction direction of the spring by the cooperation between the limit rod and the screw rod, ensuring that the adjustment mechanism as a whole can play a supporting and connecting role, and adjusts the impact resistance and pressure resistance by rotating the adjustment knob to squeeze the spring to adjust the spring contraction degree. The device allows the user to accurately control the supporting force to ensure that the supporting system is always in the best stress state, avoiding safety hazards caused by overload or structural instability caused by underload, and solves the problem that the impact resistance and pressure resistance cannot be adjusted according to the actual force intensity, which has a great impact on its actual use effect.

[0015] 2. The connecting shaft of the utility model ensures that the connecting shaft and the rotating block rotate synchronously inside the mounting block through the cooperation between the limit strip and the assembly hole. The inclination angle of the adjusting mechanism is determined by rotating the mounting block. When the angle is adjusted appropriately, the fixing bolt passes through the threaded hole on the surface of the mounting block and is threadedly installed inside the threaded hole on the surface of the connecting shaft. The angle of the connecting shaft and the mounting hole is fixed to prevent the adjusting mechanism from rotating at one end of the angle fixing mechanism during the force-bearing process of the equipment, resulting in the problem that the angle fixing mechanism cannot play a supporting role. In summary, when installing the equipment, the inclination angle of the adjusting mechanism can be flexibly adjusted according to the situation, so that the adjusting mechanism can adjust the appropriate force angle. At the same time, the equipment can change the angle through the adjusting mechanism to adapt to various installation environments, improve the scope of use, and make the equipment reusable.
