TECHNICAL FIELD

[0001] The application relates to the technical field of construction engineering protection, in particular to a protection device for building safety engineering. BACKGROUND

[0002] In the field of building safety engineering, the high-altitude operation protection device needs to consider rigid support and flexible buffering capacity to cope with falling impact, object collision and other risks. Traditional devices mostly rely on the combination of rigid frames and protective nets, which can provide basic protection but have problems such as passive impact resistance and low energy absorption efficiency.

[0003] Current non-Newtonian fluid protection devices usually encapsulate materials inside the support structure and rely on external force to trigger fluid state changes. For example, the fluid hardens instantly to dissipate energy when an impact occurs, and returns to a soft state after the impact ends.

[0004] However, in actual use, the performance of non-Newtonian fluid is easily affected by temperature. The viscosity decreases at high temperatures, resulting in reduced rigidity, and the fluidity decreases at low temperatures, affecting the buffering response. In addition, it relies on passive triggering and cannot actively adjust the softness according to construction needs.
