DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 2 、 Figure 3 and Figure 5 The utility model provides an embodiment of a stabilization and protection device for a foundation pit of a water conservancy project, comprising a protective plate body 1, the bottom of which is rotatably connected to a side plate 2, so that the side plate 2 can flexibly rotate relative to the protective plate body 1. An adjustment component is provided on the outside of the side plate 2, and mounting grooves 5 are respectively provided on both sides of the protective plate body 1. A support mechanism 3 is provided inside the mounting groove 5, providing storage and installation space for the support mechanism 3. The support mechanism 3 is located on both sides of the side plate 2, providing a stable supporting force to the protective plate body 1 from the side, thereby enhancing the stability of the overall structure;

[0033] The adjustment assembly includes two diagonal braces 21, which are rotatably connected to the outside of the side panels 2. The diagonal braces 21 can change their angles as the side panels 2 rotate. The ends of the two diagonal braces 21 away from the side panels 2 are rotatably connected to connecting blocks 22, and the angles change when the diagonal braces 21 rotate.

[0034] The connecting block 22 is fixedly connected to two fixing blocks 23 on the outside. A first adjustment screw 24 is rotatably connected to the internal parts of the two fixing blocks 23, which is used to secure the diagonal support rod 21 to the protective plate body 1. The protective plate body 1 is provided with multiple threaded grooves 27 on the outside. The first adjustment screw 24 is externally threaded into the internal parts of the threaded grooves 27. The multiple threaded grooves 27 are arranged in a rectangular shape on the outside of the T-slots 26. Once the protective plate body 1 is attached to the base surface, it can be secured by screwing the first adjustment screw 24 into the threaded grooves 27. The fixing blocks 23 are slidably connected to the outside of the protective plate body 1. The connecting block 22 is fixedly connected to the outside of the T-slots 26 on the outside of the protective plate body 1. The T-slots 25 are slidably connected to the inside of the T-slots 26, providing a stable position for the movement of the connecting block 22. Multiple ground spikes 6 are fixedly connected to the bottom of the protective plate body 1 and the side panels 2. These spikes can be inserted into the ground to enhance the friction and anchoring force between the device and the ground.

[0035] Reference Figure 1 and Figure 4The supporting mechanism 3 comprises two first supporting rods 31, one end of the two first supporting rods 31 being rotatably connected to the inside of the mounting groove 5, so as to realize quick unfolding and storage of the supporting mechanism 3. The inside of the first supporting rod 31 is fixedly connected with a spring 32, one end of the spring 32 being fixedly connected with a plug post 33. By utilizing the elastic potential energy of the spring 32, when the plug post 33 is pressed by external force, the spring 32 is compressed to store energy, and after the external force disappears, the plug post 33 can be popped out again. The outside of the first supporting rod 31 is slidably connected with a second supporting rod 34, so that the second supporting rod 34 can be extended and retracted relative to the first supporting rod 31, thereby changing the overall length of the supporting mechanism 3. The outside of the second supporting rod 34 is provided with a plurality of plug holes 35, and the plug post 33 is inserted into the inside of the plug hole 35. Under the action of the spring 32, the plug post 33 can be inserted into the plug hole 35 at different positions, thereby realizing the fixation of the extension and retraction position of the second supporting rod 34.

[0036] The second supporting rod 34 is provided with a fixing assembly 4 away from the bottom of the first supporting rod 31, and the fixing assembly 4 comprises an adapter block 41 rotatably connected to the bottom of the second supporting rod 34, so that the adapter block 41 can better adhere to the ground and adapt to changes in different terrains. The inside of the adapter block 41 is threadedly connected with a second adjusting screw 42, and the bottom of the second adjusting screw 42 is fixedly connected with a protruding block 43. The outside of the plug post 33 is slidably connected to the inside of the first supporting rod 31. When the second adjusting screw 42 is screwed downward, the protruding block 43 can penetrate into the ground, thereby further increasing the friction and anchoring force between the adapter block 41 and the ground, strengthening the supporting effect of the supporting mechanism 3 on the protective plate body 1, and preventing the protective plate body 1 from tilting or collapsing when subjected to external force. The outside of the second supporting rod 34 is arranged in the inside of the mounting groove 5, which can effectively protect the supporting mechanism 3 in the non-use state.

[0037] Working principle: first, move the protective plate body 1 to the position needing protection in the foundation pit, then rotate the side plate 2 downward, so that the ground peg 6 is inserted into the ground. At this time, the movement of the inclined supporting rod 21 makes the T-shaped block 25 slide in the T-shaped groove 26. After adjusting the angle of the protective plate body 1 to make it adhere to the base surface, the fixing assembly 4 is rotated and screwed into the T-shaped groove 26, thereby fixing the protective plate body 1 so that it can adhere to different inclined base surfaces of the foundation pit;

[0038] Secondly, the supporting mechanism 3 is rotated out of the mounting groove 5, and then the plug post 33 is pressed into the first supporting rod 31, so that the spring 32 is compressed to store energy, thereby moving the second supporting rod 34 downward from the outside of the first supporting rod 31. When the adapter block 41 contacts the ground, the plug post 33 is inserted into another plug hole 35 by the tension of the spring 32. Then, the second adjusting screw 42 is screwed downward, so that the second adjusting screw 42 drives the protruding block 43 to penetrate into the ground, thereby supporting the protective plate body 1 by the supporting mechanism 3, so that it can stably protect the foundation pit.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
