[0020] In order to make the above objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific implementations disclosed below.
[0021] Please refer to Figs. 1 to 3 The present embodiment is a kind of transmission tower foundation anti-collision device based on foam aluminum material, including anti-collision box 1, outer buffer layer 2, middle buffer layer 3 and inner buffer layer 4. Anti-collision box 1 is surrounded in the iron tower foundation 5, and has anti-collision cavity, and outer buffer layer 2, middle buffer layer 3 and inner buffer layer 4 are sequentially installed from outside to inside in the anti-collision cavity, wherein the material of outer buffer layer 2 and inner buffer layer 4 is foam aluminum material, and the material of middle buffer layer 3 is fabric hollow polyurethane board.
[0022] The first protective barrier is formed by the combination of outer buffer layer 2 and anti-collision box 1, which can effectively withstand the initial impact force from the rolling stone; the impact energy can be effectively dispersed and absorbed by the two outer buffer layers 2 and inner buffer layers 4 of foam aluminum material, reducing the transmission impact on the inner structure; the flexibility and buffering performance of the anti-collision device can be enhanced by setting the middle buffer layer 3 of fabric hollow polyurethane board in the middle layer of the two foam aluminum materials; by reasonably combining the foam aluminum with higher strength and better energy absorption with the stable and effective polyurethane material to form the core energy dissipation material, the advantages of the two can be fully utilized, which can effectively improve the impact resistance and reduce the maintenance cost, and adapt to complex terrain and harsh environment.
[0023] Foam aluminum material is a new type of lightweight high-strength material with excellent energy absorption performance and impact resistance, which has been widely used in aerospace, automobile and other fields in recent years. Its unique honeycomb structure can effectively disperse and absorb impact energy, and has good corrosion resistance and thermal stability, suitable for use in harsh environments. Polyurethane material itself has excellent vibration absorption performance and can be used as damping and buffering material. When external impact force acts on the polyurethane material, it will deform, absorb impact force and gradually recover to its original shape.
[0024] In order to facilitate installation, the anti-collision box 1 comprises an inner side plate 11, an outer side plate 12, a top plate 13 and a bottom plate 14, which are made of steel plates, the inner side plate 11 is attached to the outer surface of the tower base 5, the outer side plate 12 is located at a predetermined distance outside the inner side plate 11, and the top and bottom of the outer side plate 12 are connected with the top and bottom of the inner side plate 11 through the top plate 13 and the bottom plate 14 respectively. During installation, the inner side plate 11 can be first fixed on the outer surface of the tower base 5, then the bottom plate 14 and the outer side plate 12 are welded, the buffer layer is placed in the anti-collision cavity, and finally the top plate 13 is welded.
[0025] In order to adapt to the anti-collision installation of different specifications of tower bases 5, the inner side plate 11, the bottom plate 14 and the outer side plate 12 are fixedly connected to form an installation unit block, and the inner side plate 11 is provided with a fixing hole 15, which can be used to fix the inner side plate 11 on the tower base 5 through bolts, and the outer side plate 12 is provided with a surrounding plate 16 around it, and the surrounding plate 16 is provided with a mounting hole 17, so that each box surface of the anti-collision box 1 can be formed by fixedly connecting a plurality of installation unit blocks through bolts. During installation, the inner side plate 11 can be first fixed on the outer surface of the tower base 5 through the fixing hole 15, and the adjacent outer side plates 12 can be butt-jointed through the mounting hole 17, the buffer layer is installed after each side box surface is installed, and finally the top plate 13 is welded.
