[0017] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0018] Embodiment 1:
[0019] See also Figure 1As shown, the utility model provides an air defense alarm for civil air defense projects with high safety performance and a protective cover, comprising a base 1, a support column 2 is fixedly installed on the top of the base 1, a support frame 4 is fixedly installed on the upper end of the support column 2, a top plate 6 is fixedly installed on the top of the support frame 4, an alarm body 5 is fixedly installed inside the support frame 4, buffer springs 7 are welded on both sides of the top of the top plate 6, a buffer plate 8 is fixedly installed on the upper end of the buffer spring 7, protective covers 9 are fixedly installed on both ends of the buffer plate 8, a special-shaped spring 12 is fixedly installed on the top of the protective cover 9, and a shielding cover 13 is fixedly installed on the upper end of the special-shaped spring 12.
[0020] The application of the protective cover 9 and the shielding cover 13 in the present technical solution can effectively protect the upper part and form a protective structure. At the same time, the buffer spring 7 and the shielding cover 13 are added to the top and bottom of the protective cover 9, which can shield and buffer the falling objects thrown from high altitude or unknown objects, and prevent the protective cover 9 from being damaged by direct collision.
[0021] Embodiment 2:
[0022] On the basis of embodiment 1, the utility model is as follows Figure 3 As shown, reinforcement rods 3 are welded on both sides of the top of the base 1 , and the upper ends of the reinforcement rods 3 are fixedly installed on the outside of the support column 2 .
[0023] Use Figure 1 In the technical solution shown, the reinforcement rod 3 can reinforce both sides of the support column 2 to increase the firmness.
[0024] Secondly, in the technical solution, rubber support pads 10 are fixedly installed on both sides of the top of the buffer plate 8, and the upper end of the rubber support pad 10 is connected to the bottom of the shielding cover 13; side baffles 11 are welded on both sides of the bottom of the buffer plate 8, and the lower end of the side baffle 11 extends to the bottom of the top plate 6, and the lower end of the side baffle 11 is bent.
[0025] Its use is as Figure 1 In the technical solution shown, the rubber support pad 10 supports and buffers the bottom of the protective cover 9, further enhancing the overall anti-collision ability, and the side baffle 11 can limit the two ends of the buffer plate 8 to ensure that it will not produce a large offset when moving. At the same time, the bend at the lower end of the side baffle 11 can form a limiting structure with the bottom of the top plate 6 to prevent the buffer plate 8 from moving too much.
[0026] Embodiment three:
[0027] The utility model Figure 1-Figure 3As shown, it is disclosed that buffer pads 14 are fixedly installed on both sides of the top of the protective cover 9, and the top of the buffer pad 14 is fixedly installed with the bottom of the shielding cover 13; the shielding cover 13 and the protective cover 9 are both funnel-shaped, and the shielding area of the protective cover 9 is larger than the length of the alarm body 5.
[0028] By adopting the above technical solution, the buffer pad 14 can be used together with the special-shaped spring 12 to achieve the purpose of shock-proof buffering and enhance the shock-proof strength of the shielding cover 13. At the same time, the protective cover 9 can shield the upper part of the alarm in a large range.
[0029] The working principle of the utility model is that the base 1 can reinforce the bottom of the support column 2. During the long-term use of the alarm, the protective cover 9 on the top can protect the alarm from wind and rain. When the upper part of the shielding cover 13 is hit by objects thrown from high altitude or unknown objects, the impact force generated will squeeze the special-shaped spring 12 and the buffer pad 14 through the shielding cover 13, and at the same time, the impact squeezing force will be transmitted to the protective cover 9 and the buffer plate 8. The buffer plate 8 squeezes and supports the buffer spring 7 downward, thereby achieving the effect of buffering and shock resistance, and ensuring the normal use of the internal alarm.
