[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model proposes: a water conservancy construction cofferdam reinforcement structure, including a shell 1, an arc-shaped rubber baffle 2, a fixed pressure strip 3, a counterweight 4, a limit rod 5 and a connecting frame 6, the shell 1 is fixedly connected with the arc-shaped rubber baffle 2, and the edge of the arc-shaped rubber baffle 2 is pressed with a fixed pressure strip 3, which is convenient for stably installing the arc-shaped rubber baffle 2 on the shell 1, so that the two can be stably used together, and a buffer component for blocking and alleviating the impact of water waves is formed on the water-facing surface of the shell 1, which alleviates the impact of water waves and avoids the water-facing surface of the cofferdam being damaged by water waves, and the water-facing surface of the cofferdam is effectively strengthened, and the shell 1 is equipped with the following components inside. The spaced-apart limiting struts 7 are used to limit the deformation of the arc-shaped rubber baffle 2 to ensure that the arc-shaped rubber baffle 2 can be used stably. A counterweight 4 is arranged at the bottom of the shell 1 to ensure that the entire structure can be stably suspended in the water to effectively block the waves. A connecting frame 6 is fixedly connected to the side of the shell 1 away from the arc-shaped rubber baffle 2. A limiting rod 5 is arranged on the connecting frame 6. One end of the limiting rod 5 is fixedly connected to the limiting plug rod 501. The shell 1 and the arc-shaped rubber baffle 2 are placed in the water on the water-facing side of the cofferdam by means of the cooperation of the connecting frame 6 and the limiting rod 5. The length of the limiting rod 5 is determined according to actual usage requirements to effectively protect the cofferdam.

[0024] like Figure 1 and Figure 2As shown, in some embodiments, an overlap groove for matching with the fixed pressure strip 3 is opened at the edge of the arc-shaped rubber baffle 2, and the fixed pressure strip 3 is fixedly connected to the corresponding part of the shell 1 by screws. The arc-shaped rubber baffle 2 is stably connected to the shell 1 by the fixed pressure strip 3, and an arc plate for blocking water waves is formed on the water-facing surface of the shell 1. When the water waves hit the arc-shaped rubber baffle 2, the water waves are thrown upward through the diversion on the surface of the arc plate, thereby alleviating the impact of the water waves. In this process, the water waves hit the water surface of the arc plate. When the impact force acts on the arc-shaped rubber baffle 2, the arc-shaped rubber baffle 2 will produce appropriate deformation to mitigate the impact of water waves and prevent the cofferdam from being damaged by water waves. The water-facing surface of the arc-shaped rubber baffle 2 is provided with spoiler bars 201 distributed at equal intervals to enhance the effect of the arc-shaped rubber baffle 2 on intercepting water waves. The other side of the arc-shaped rubber baffle 2 does not contact the limiting support rod 7 inside the shell 1, and a blocking member is formed on one side of the arc-shaped rubber baffle 2 to avoid excessive deformation of the arc-shaped rubber baffle 2 and ensure stable use.

[0025] like Figure 2 and Figure 3 As shown, in some embodiments, a connecting strip 101 is fixedly connected to the bottom of the shell 1, and a plug-in board 401 integrally arranged at the upper edge of the counterweight block 4 is plugged between the two connecting strips 101 at the bottom of the shell 1. The counterweight block 4 is stably installed at the bottom of the shell 1 by utilizing the cooperation between the two, so that the entire structure can be stably suspended in the water to effectively block the waves. The counterweight block 4 gradually becomes thinner from the middle part to the four sides, ensuring that the center of gravity of the counterweight block 4 is in the middle position, avoiding the center of gravity shift causing the entire structure to tip over, thereby improving the stability of the entire structure during use.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, a sealing plug 104 is embedded in the perforation opened on the side wall of the shell 1, so that when adjusting the suspension depth of the shell 1 in the water, the sealing plug 104 can be removed, so that water can flow into or out of the shell 1 from the perforation, thereby changing the weight of the entire structure and completing the adjustment operation of the suspension depth. Air holes 103 are opened on the upper part of the two side walls of the shell 1 to balance the air pressure in the internal cavity during the process of filling or draining water in the shell 1, thereby ensuring smooth water filling and drainage, and the middle position of the two side walls of the shell 1 is fixedly connected with a lap buckle 102 to facilitate the stable connection of two adjacent shells 1 together, thereby forming a stable belt-shaped protective structure on the water-facing surface of the cofferdam, thereby providing stable and effective protection for the cofferdam.

[0027] like Figure 2As shown, in some embodiments, both ends of the connecting frame 6 are fixedly connected to the outer wall of the shell 1 through a rod seat 601, and the connecting frame 6 is stably installed on the shell 1, so that the connecting frame 6 can be used together with the limiting rod 5 to limit the entire structure in the water on the water-facing surface of the cofferdam, thereby effectively protecting the water-facing surface of the cofferdam. The connecting ring 502 arranged at the end of the limiting rod 5 is sleeved on the connecting frame 6, and the connecting ring 502 is slidably connected to the connecting frame 6, so that the limiting rod 5 can slide on the connecting ring 502 to adjust the position, so that after the suspension depth of the shell 1 in the water changes, the connection position of the limiting rod 5 and the connecting frame 6 will be appropriately changed, ensuring that the suspension depth of the shell 1 in the water can be flexibly adjusted at any time after installation and fixation.

[0028] like Figure 2 As shown, in some embodiments, a water storage cavity is formed between the shell 1 and the arc-shaped rubber baffle 2, and the water storage cavity is connected to the perforation formed on the shell 1, so that water can be introduced into the water storage cavity through the perforation, and the water in the water storage cavity can also be discharged from the perforation, and the weight of the entire protective structure can be adjusted to adjust the depth of the entire protective structure suspended in the water to adapt to different usage requirements. It can be used together with the counterweight block 4 so that the entire structure can be stably suspended in the water to block the waves and prevent the waves from impacting and damaging the water-facing surface of the cofferdam.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
