Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-4, the utility model provides a protection device for civil engineering, which comprises a support plate 1, a connecting shaft 2 is arranged on two sides of the bottom end of the support plate 1, a separation blade 3 is fixedly connected on one side of the connecting shaft 2, a connecting post 5 is fixedly arranged on the bottom of the support plate 1, a compression spring 4 is arranged on one side of the connecting post 5, the connecting post 5 is fixedly connected with the separation blade 3 through the compression spring 4, a connecting plate 14 is arranged above the support plate 1, a sliding rod 11 is fixedly arranged on the bottom of the connecting plate 14, a sleeve 10 is sleeved on the outer side wall of the sliding rod 11, a first spring 9 is arranged on one side of the sleeve 10, a second rotating shaft 8 is fixedly arranged below the bottom of the first spring 9, a movable rod 7 is fixedly arranged on one side of the second rotating shaft 8, a first rotating shaft 6 is fixedly arranged on the other end of, the bottom of the connecting plate 14 is fixedly provided with a lug 15 at a position corresponding to the groove 16.
