The invention discloses an energy-consuming protection net, comprising a base and columns. The base is fixedly connected with an energy-consuming device above, and the top of the energy-consuming device is fixedly connected with a support rod. The end of the support rod is fixedly connected with the columns. Between the columns are fixed a steel wire mesh. The energy-consuming protection net has reasonable design and can transfer the impact force exerted by the external force on the protective net so that the force is controlled in a range by the folds deformation of the energy-consuming device, and the energy-consuming device absorbs most of the energy, so that the energy is absorbed. The force on the protection net is greatly reduced, while the columns have also been protected, and the energy-consuming device is convenient to replace, economical and feasible after damaged.
