TECHNICAL FIELD

[0001] The utility model relates to the technical field of protective net, especially with energy dissipation device of protective net with pressure reducing structure. BACKGROUND

[0002] Rockfall is a common natural disaster, which refers to the phenomenon that stones at high places fall to the ground or low-lying places under the action of gravity. The rockfall protective net is an engineering measure for preventing geological disasters such as landslides and rock falling, which has the effect of stabilizing soil and rock and preventing them from sliding or falling.

[0003] At present, most of the existing protective nets use anchor rods in cooperation with supporting ropes to cover and fix the protective nets on the slopes with potential rockfall, which has poor buffer energy dissipation function. When the stones are loose, it is easy to cause local overloading of the protective net and damage the protective net, affecting the safety performance and service life of the protective net.

[0004] Therefore, in view of the problem that the existing protective net has poor buffer energy dissipation function, affecting the safety performance and service life of the protective net, an energy dissipation device with pressure reducing structure can be designed. The protective net is fixed on the slope through the energy dissipation structure, so that it can be effectively buffered and energy dissipated when it is locally impacted, avoiding damage. SUMMARY

[0007] Preferably, the energy dissipation rod and the hook are integrally formed, and the upper end of the threaded rod is fixedly connected with the energy dissipation rod.

[0008] Preferably, the through hole is arranged in a vertical penetrating manner with respect to the sleeve joint, and the energy dissipation rod and the threaded rod are slidably sleeved with the inner side of the through hole.

[0009] Preferably, the energy dissipation spring is sleeved with the outer side of the energy dissipation rod, the upper end of the energy dissipation spring abuts against the lower end of the sleeve joint, and the lower end of the energy dissipation spring abuts against the upper end of the limiting ring.

[0010] Preferably, the limiting ring and the outer side of the energy dissipation rod and the threaded rod are movably sleeved, the lower end of the limiting ring abuts against the upper end of the adjusting nut, and the outer side of the adjusting nut and the threaded rod are threadedly connected.

[0011] Preferably, the energy-dissipating spring, the limiting ring, and the adjusting nut are all compatible with the inner side of the protective sleeve, and the upper end of the inner side of the protective sleeve is provided with an internal thread, which is compatible with the external thread.

[0012] Preferably, the sealing stop and the protective sleeve are integrally formed and interlock with the sealing groove. A sealing ring is fixedly installed on the inner side of the sealing groove, and the upper end of the sealing stop is tightly fitted with the sealing ring.

[0013] The beneficial effects of this utility model are:

[0014] This energy dissipation device for protective netting with a pressure-reducing structure works by hanging hooks at appropriate positions on the protective netting and inserting protective sleeves into the slope to reinforce the netting. When the netting is subjected to force at that position, the hooks pull the energy dissipation rods to slide within the through holes, allowing the energy dissipation springs to buffer the tension on the rods, thereby reducing pressure and dissipating energy on the protective netting. Subsequently, each structure can be removed from the inside of the protective sleeve by rotating the sleeve, and each structure can be disassembled and replaced by removing the adjusting nuts, making it convenient and quick.
