[0028] The present application will be further described below in combination with the drawings.

[0029] Embodiment 1

[0031] First connecting plate 2 and second connecting plate 3 are installed in explosion -proof housing 1. First connecting plate 2 is fixedly connected with explosion -proof housing 1. Second connecting plate 3 is fixedly connected with explosion -proof housing 1. A plurality of triangular openwork board 5 are equidistantly installed in explosion -proof housing 1, and the plurality of triangular openwork board 5 are slidably connected with first connecting plate 2 and second connecting plate 3 respectively. Second connecting plate 3 is provided with a sliding groove 8. A plurality of sliders 9 are equidistantly installed in the sliding groove 8 respectively. A plurality of connecting rods 10 are fixedly connected with a plurality of sliders 9 at one end respectively, and are fixedly connected with a plurality of triangular openwork board 5 at the other end respectively. A plurality of rotating arms 11 are rotatably connected with a plurality of connecting rods 10 respectively. Two ends of each rotating arm 11 are rotatably connected with one end of the rotating arm 11 on the two sides respectively. Explosion -proof housing 1 is provided with a through -opening 12. Handle 7 is rotatably connected with second connecting plate 3 through the through -opening 12. One end of handle 7 is rotatably connected with one end of the nearest rotating arm 11. A plurality of triangular openwork board 5 are placed in opposite directions crossing each other. Rotating handle 7, handle 7 drives the nearest rotating arm 11 to rotate, because the two ends of a plurality of rotating arms 11 are rotatably connected with one end of the rotating arm 11 on the two sides respectively, and a plurality of connecting rods 10 are fixedly connected with a plurality of sliders 9 at one end respectively and are fixedly connected with a plurality of triangular openwork board 5 at the other end respectively, a plurality of triangular openwork board 5 are moved back and forth along the direction of sliding groove 8 by rotating handle 7, when a plurality of triangular openwork board 5 are unfolded along sliding groove 8, a plurality of triangular openwork board 5 are not transparent between them, a plurality of triangular openwork board 5 can circulate air between them, improve the protectiveness and energy -absorbing efficiency of protective grid. When the protective grid needs to be transparent or the triangular openwork board 5 needs to be retracted, rotating handle 7 because a plurality of rotating arms 11 two ends are rotatably connected with one end of the rotating arm 11 on the two sides respectively, and a plurality of connecting rods 10 are fixedly connected with a plurality of sliders 9 at one end respectively and are fixedly connected with a plurality of triangular openwork board 5 at the other end respectively, so that a plurality of triangular openwork board 5 retract along the sliding groove 8 towards one side of handle 7, improve the applicability of protective grid. Explosion -proof housing 1 can resist impact, and can effectively prevent the spread of explosion. Explosion -proof housing 1 has strong pressure -resisting and impact -resisting ability. When explosion or impact occurs, explosion -proof housing 1 can limit pressure and energy outside the shell, and can protect the internal parts. Explosion -proof housing 1 can create a relatively stable and safe working environment for the protective grid. This not only can prolong the service life of the protective grid, reduce the maintenance and replacement cost of the protective grid, but also can ensure the stable operation of the protected equipment at the critical moment.

[0032] A plurality of fixed pieces 4 are respectively fixedly connected with the explosion-proof shell 1. A plurality of protective layers 6 are respectively fixedly installed outside the plurality of triangular hollow plates 5. The protective grating can be fixedly installed through the plurality of fixed pieces 4. The triangular hollow plate 5 is easily affected by factors such as wear, corrosion and oxidation on the surface during long-term use. The protective layer 6 can effectively isolate the external erosion medium, reduce the wear rate of the equipment, prolong the service life of the triangular hollow plate 5, and reduce the frequency of repair and replacement of the triangular hollow plate 5, thereby reducing the production cost. At the same time, when the triangular hollow plate 5 is impacted, the protective layer 6 can protect the triangular hollow plate 5. When the hidden equipment needs to be protected, the surface of the protective layer 6 can be coated with a matte stealth layer. Because the triangular hollow plate 5 and the protective layer 6 are designed as a multi-section, the radar scattering cross section can be significantly reduced. The explosion-proof shell 1 can be made of aluminum alloy material. The density of aluminum alloy is much smaller than that of traditional metal materials such as steel. The use of aluminum alloy material can greatly reduce the weight of the shell. At the same time, it can reduce the labor intensity, improve the work efficiency, and make the equipment can be put into use more quickly. Aluminum alloy has excellent heat conduction performance, can quickly conduct heat, can ensure that the protected equipment operates within the appropriate temperature range, prolongs the service life of the equipment, and improves the reliability and stability of the equipment. In some harsh working environments, a dense oxide film can be formed on the surface of the aluminum alloy. This oxide film has good corrosion resistance and can prevent further contact between the external corrosive medium and the aluminum alloy matrix, thereby reducing maintenance costs. Even if the oxide film is damaged to some extent, the aluminum alloy can quickly re-form an oxide film in the air and continue to play its corrosion-resistant role. Aluminum alloy can be used stably in humid and corrosive gas environments for a long time. The alloy has good plasticity and processability, and can be made into various shapes and sizes through various processing techniques.

[0033] The handle 7, the rotating arm 11 and the connecting rod 10 can be made of stainless steel material, which has excellent corrosion resistance. In many environments, ordinary steel is easily chemically reacted with air, water, acid, alkali and other substances, resulting in rust and corrosion, thereby affecting its performance and service life. While stainless steel contains a certain proportion of chromium elements, a dense chromium oxide protective film is formed on the surface, which can effectively prevent further corrosion of the internal steel by external corrosive media. The use of stainless steel material can greatly reduce the cost of maintenance and replacement. Stainless steel material also has high strength and good toughness, can withstand large external forces without deformation or fracture. Can withstand a certain impact force. The parts made of stainless steel can withstand complex working load and ensure the normal operation of the equipment. Stainless steel has a smooth and bright surface, with a modern and technological feel, which can add aesthetic appeal to various products. Stainless steel has good processing performance and can be formed and processed by various processing techniques. Stainless steel material is a recyclable material with high recovery rate. After the product's service life ends, the stainless steel material can be recycled and reprocessed to make new products, reducing the consumption of natural resources and waste emissions. The use of stainless steel material is more in line with the concept of environmental protection and sustainable development.

[0034] The working principle of the adjustable high-efficiency energy-absorbing protective grille will be described below.

[0035] As shown in Figures 1-6 When multiple triangular hollow plates 5 need to be expanded, rotate the handle 7, which drives the nearest rotating arm 11 to rotate. Because the two ends of the multiple rotating arms 11 are respectively rotatably connected with one end of the rotating arms 11 on both sides, and one end of the multiple connecting rods 10 is respectively fixedly connected with the multiple sliding blocks 9, and the other end is respectively fixedly connected with the multiple triangular hollow plates 5, the multiple triangular hollow plates 5 are synchronously moved along the direction of the sliding groove 8. When the multiple triangular hollow plates 5 are expanded along the sliding groove 8, the multiple triangular hollow plates 5 are not transparent to each other, and air can flow between the multiple triangular hollow plates 5, improving the protection and energy-absorbing efficiency of the protective grille. When the protective grille needs to be transparent or the triangular hollow plates 5 need to be retracted, the handle 7 is rotated in the opposite direction. Because the two ends of the multiple rotating arms 11 are respectively rotatably connected with one end of the rotating arms 11 on both sides, and one end of the multiple connecting rods 10 is respectively fixedly connected with the multiple sliding blocks 9, and the other end is respectively fixedly connected with the multiple triangular hollow plates 5, the multiple triangular hollow plates 5 are retracted to one side of the handle 7 along the sliding groove 8, improving the applicability of the protective grille. The protective grille can be fixedly installed through the multiple fixing pieces 4. In general, this protective grille has the characteristics of convenience, agility and high-efficiency energy-absorbing.

[0036] The utility model has made the detailed description to the utility model generally above, but can make some modification or improvement to it on the basis of the utility model, this is obvious to the general skilled person in the technical field.
