[0037] Example 1

[0038] like Figures 1-6 As shown, this utility model discloses a safety protection structure for water conservancy construction, comprising:

[0039] The protective net 2 is wound outside the winding rod 14 rotatingly installed in the inner cavity of the storage cylinder 1, the side of the storage cylinder 1 is provided with an inlet and outlet 11 for the protective net 2 to pass out, the storage cylinder 1 is designed in a cylindrical shape, and the inlet and outlet 11 is designed as a rectangular opening extending from the top of one side of the storage cylinder 1 to the bottom of the same side.

[0040] The limiting frame 3 is provided outside the protective net 2 and is designed as a rectangular frame capable of sliding outside the protective net 2.

[0041] The positioning rod 33 is provided at the bottom of the limiting frame 3 and is used to position the bottom of the limiting frame 3.

[0042] The fixing mechanism is provided outside the limiting frame 3 and is used to fix the position of the limiting frame 3 on the protective net 2 after the position of the limiting frame 3 is adjusted.

[0043] The water conservancy construction safety protection structure disclosed in the application can release the protective net 2 by pulling the protective net 2 to drive the axial rotation of the winding rod 14 during safety protection, can accurately align the unfolded protective net 2 with the boundary of the protection area during the deployment process, can quickly fix the limiting frame 3 by inserting the ground into the ground by using the ground-inserting positioning rod 33, can fix the position of the limiting frame 3 by using the fixing mechanism, can effectively eliminate the asymmetric deformation of the traditional protective net 2 due to the self-weight, can ensure that the protective net 2 maintains the best form in the vertical dimension, can wind the protective net 2 outside the winding rod 14 in the storage cylinder 1 when in the non-operation period, can make the protective net 2 compactly stored in the cavity of the storage cylinder 1, can realize the space optimization rate, and can significantly improve the environmental adaptability of the device. While maximizing the protection efficiency, the deployment efficiency and storage convenience are also considered.

[0044] The water conservancy construction safety protection structure disclosed in the application can adjust the unfolded length according to the actual area of the protection area by pulling the protective net 2, can realize perfect adaptation to the construction environment, can significantly improve the mobility of the protection operation by using the quick unfolding and flexible winding mechanism, can make the device respond to the engineering demand in real time, and such operation design not only greatly improves the protection efficiency, but also effectively reduces the labor intensity of the operation personnel, thereby providing more convenient protection for the construction site.

[0045] As a preferred example of the application, the fixing mechanism includes a movable fixing bolt 31 penetrating the limiting frame 3 and threadedly connected with the limiting frame 3, and the end of the fixing bolt 31 close to the protective net 2 is abutted with the protective net 2 by friction.

[0046] By rotating the fixing bolt 31, it can be pushed into the limiting frame 3, so that the end of it close to the protective net 2 is against the protective net 2 through friction, thereby fixing the limiting frame 3. This effectively eliminates the asymmetrical deformation caused by the weight of the traditional protective net 2, and ensures that the protective net 2 maintains the best shape in the vertical dimension.

[0047] As a preferred example of this application, flexible rubber strips 21 are fixedly connected to both the upper and lower ends of the protective net 2. By setting the flexible rubber strips 21, on the one hand, the strength of the upper and lower ends of the protective net 2 is increased, avoiding the breakage of the protective net 2 caused by traction, and further improving the tensile strength of the protective net 2. On the other hand, when the fixing bolt 31 limits the upper part of the protective net 2, it is used to increase the friction between the fixing bolt 31 and the protective net 2, thereby improving the firmness of the fixing bolt 31 in limiting the upper part of the protective net 2, and further improving the effect of preventing the protective net 2 from sagging and bending.

[0048] As a preferred example of this application, a baffle 22 is fixedly connected to the side of the protective net 2 away from the winding rod 14.

The width of the baffle 22 is greater than the width of the inlet and outlet 11, and the curvature of the side closer to the protective net 2 matches the outer curvature of the storage cylinder 1. With the setting of the baffle 22, when the protective net 2 is wound up, the baffle 22 is limited to the outside of the storage cylinder 1 and fits against the outside of the storage cylinder 1, so as to prevent one end of the protective net 2 from entering the storage cylinder 1 through the inlet and outlet 11 when the protective net 2 is wound up inside the storage cylinder 1, so as to facilitate the pulling of the protective net 2 for the next use.

[0049] As a preferred example of this application, the bottom of the limiting frame 3 is provided with a slot 32, and a threaded hole is provided in the slot 32. The positioning rod 33 at the bottom of the limiting frame 3 is threadedly connected to the threaded hole. By turning the positioning rod 33, the length of the positioning rod 33 placed below the limiting frame 3 can be adjusted, thereby adjusting the depth of the positioning rod 33 inserted into the ground, ensuring the stability of the positioning rod 33 in limiting the limiting frame 3. In conjunction with the design of the slot 32, when the protective net 2 is rolled up, the bottom of the positioning rod 33 is screwed into the slot 32 to prevent the positioning rod 33 from being unable to roll the protective net 2 into the storage cylinder 1 through the inlet and outlet 11.

[0050] As a preferred example of this application, the end of the baffle 22 away from the protective net 2 is fixedly connected to a connecting rod 23, which is shaped like a "7". The end of the storage tube 1 away from the inlet / outlet 11 is fixedly connected to a connecting tube 24. By inserting the connecting rod 23 into the connecting tube 24, multiple identical devices can be connected in series. By adopting the plug-in design, the coverage of the protective net 2 can be quickly expanded, and the overall spatial adaptability of the device can be improved.

[0052] As a preferred example of the present application, the receiving cylinder 1 is fixedly connected with a bottom plate 5 at both ends, the bottom of the bottom plate 5 is on the same horizontal plane as the bottom of the receiving cylinder 1, and a fixed rod 51 is movably penetrated through the bottom plate 5, the fixed rod 51 is arranged in a T shape, and through the arrangement of the fixed rod 51 and the bottom plate 5, when the receiving cylinder 1 is used, the fixed rod 51 is inserted into the ground, and the bottom plate 5 supports the receiving cylinder 1, further improving the stability of the receiving cylinder 1 when it is used.

[0053] As a preferred example of the present application, the top of the receiving cylinder 1 is provided with a driving disc 13, the bottom of the driving disc 13 is fixedly connected with a driving shaft 12, and the driving shaft 12 is rotatably penetrated through the receiving cylinder 1 and fixedly connected with the top end of the winding rod 14, through the arrangement of the driving disc 13, the operator can conveniently hold and rotate, and then conveniently drive the winding rod 14 to rotate to wind the protective net 2.

[0054] The water conservancy construction safety protection structure disclosed in the present application converts the traditional fixed frame type protection structure into a stretchable and retractable net winding type design, quickly pulls out the protective net 2 when needed, and realizes accurate positioning and fixing through the limiting frame 3 and the ground-inserted positioning rod 33, so that the protection range can flexibly adapt to construction areas of different shapes and sizes, while avoiding the defects of large occupation and difficult transportation of the fixed frame. During the non-operation period, the protective net 2 can be compactly retracted into the cylindrical receiving cylinder 1, the built-in driving disc 13 and winding rod 14 cooperate with the baffle 22 and the permanent magnetic adsorption structure to ensure the neatness and reliability during winding, to reduce the physical exertion of the operator while ensuring the stability of the protective net 2 in the vertical direction, and the flexible rubber strip 21 improves the tensile strength and durability of the net body. The support of the bottom plate and the T-shaped fixed rod 51 further improves the stability of the device in complex terrain, and the plug-in design of the connecting rod 23 and the connecting cylinder 24 enables multiple units to be quickly spliced and expanded to cover a larger area, thereby significantly enhancing the mobility and reliability of on-site protection on the basis of improving deployment efficiency, environmental adaptability and storage convenience.

[0055] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
