[0017] (III) Beneficial effects

[0018] The utility model provides a protective device for intercepting falling rocks on a mountain, which has the following beneficial effects:

[0019] 1. The inner and outer protective net components are set from top to bottom along the mountain, and a gap is left between them to allow the falling rocks to fall along the protective net to the edge of the road or remain in the gap space after being intercepted, which is convenient for cleaning;

[0020] 2. The inner protective net of the inner protective net assembly is used to directly intercept falling rocks. It not only receives a large impact, but is also prone to interception and accumulation of falling rocks. The inner protective net is elastically connected to the column through elastic parts. On the one hand, it can buffer the impact and extend the service life of the inner protective net. On the other hand, the inner protective net is lifted outward during the impact buffering process, especially the lower edge, so that the falling rocks after buffering and deceleration can fall to the edge of the road or remain in the gap space, which is convenient for subsequent cleaning. Even if smaller falling rocks cannot break through, they can break through the elastic force of the spring after accumulating to a certain number and weight, lift the protective net, and avoid infinite accumulation.
