Problems solved by technology

[0002] According to different installation locations, helipads are divided into ground helipads, roof helipads, and sea helipads. The roof helipad is installed on the top of the building and is used for landing the helicopter. Before the helicopter lands on the helipad, there will be a lot of noise. Large airflow, the atmospheric airflow generated by the helicopter blows the debris on the helipad to the surroundings. The function of the safety net is to pr...

The invention discloses a recoverable safety net. The recoverable safety net comprises a pre-embedded plate, supporting springs, safety net sheets and supporting arms, wherein the pre-embedded plate is mounted on the peripheral edge of a helipad 1; the supporting springs are mounted on the supporting arms at the two sides of the safety net; the safety net sheets are mounted on the upper surfaces of the supporting springs; and the supporting arms are mounted on the outer wall of the edge of the helipad. The springs are mounted inside the supporting arms to achieve buffer effect while a heavy object drops onto the safety net, so that the safety net can be recovered to the original shape after being impacted by the heavy object, and therefore, the service life of the safety net is effectivelyprolonged.

Example Embodiment

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0015] The present invention provides Figure 1-3 A recoverable safety net shown includes a pre-embedded plate 6, a support spring 3, a safety net piece 4, and a support arm 5. The pre-embedded plate 6 is fixedly connected with embedded steel bars 7, and the embedded steel bars 7 The support arm 5 is fixedly connected to the embedded board 6 by being embedded in the periphery of the helipad 1, the supporting spring 3 is fixedly connected to the surface of the supporting arm 5, and the safety mesh 4 is embedded and fixedly connected On the surface of the support spring 3.
[0016] The working principle of the present invention: figure 1 It is a schematic diagram of the internal structure of a single piece of safety net. The edge of the helipad 1 is composed of several safety nets 2, and each safety net is fixed on the outer wall of the helipad 1 through a support arm 5.
[0017] figure 2 It is a schematic diagram of the structure of a recoverable safety net system, figure 1 The schematic diagram of the internal structure of the single-chip safety net is figure 2 A view in the direction of center A, image 3 It is a schematic diagram of the embedded slab. In the early stage of the construction of the heliport 1, before the concrete is poured, the embedded steel bars 7 on the embedded slab 6 are in a bent state and are tied to the theme steel bars around the edge of the heliport 1. Each safety net is 2 Two embedded slabs 6 are provided. After the embedded slabs 6 are bound, the concrete is poured on the heliport 1 finally, and finally the panels of the embedded slabs are exposed around the heliport 1 and the embedded steel bars 7 are all buried in the heliport 1. In the concrete, each safety net piece 4 has two support arms 5, and each support arm 5 is correspondingly welded to the embedded plate 6. After the welding is completed, first install the support spring 3 to the support arm 5 one by one, and then The safety net 4 is installed on the support spring 3 one by one.
[0018] figure 2 Yes figure 1 Looking at the internal structure diagram of the safety net from the middle A direction, the support spring 3 is installed inside the support arm 5, one end of the support spring 3 is embedded in the surface of the support arm 5 and fixed by welding, and the other end of the support spring 3 is welded to the safety net 4 , The safety net piece 4 moves with the support spring 3 under the action of the force. When the helicopter is about to land on the helipad 1, the huge air current blows to the helipad 1, and the debris on the helipad 1 spreads around and floats. To safety net, there may be heavy objects in it. When the heavy objects hit the safety net 2, the traditional safety net is directly welded to the support arm, causing heavy objects to hit the safety net. When the safety net is severely deformed, and the safety net sheet is severely damaged. The structure of the present invention can effectively solve this problem. When a heavy object hits the safety net 2, the safety net sheet 4 transmits an instant force to the support. The spring 3 and the support spring 3 play a buffering role, which greatly reduces the force of heavy objects hitting the safety net 4, and after the heavy objects are cleaned up, the safety net 2 will return to its original state, achieving the effect of restoring the safety net, effectively preventing The safety net 2 is damaged or deformed by the impact of heavy objects, thereby effectively ensuring that the debris on the helipad 1 does not drift to the periphery, and protecting the life safety of personnel at the bottom of the helipad 1.
[0019] Finally, it should be noted that the above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, it is still for those skilled in the art. The technical solutions described in the foregoing embodiments can be modified, or some of the technical features can be equivalently replaced. Any modification, equivalent replacement, improvement, etc., made within the spirit and principle of the present invention shall be included in Within the protection scope of the present invention.
