Description
Technical field
Rock-fall protection net is the utility model is related to, more particularly to a kind of passive rock-fall protection net automatic warning device.
Background technology
The development of mountain area rockfall, generally use protection network carry out protective reinforcing, and passive protection net is using quite varied,
How the running status of passive protection net is evaluated in Practical Project and early warning turns into one of an important factor for must take into consideration, and has at present
Some researchs and application on passive protection net early warning, but its cost is high, it is big to be affected by the external environment, fails to report and reports situation by mistake
It is more, therefore, a kind of passive rock-fall protection net automatic warning device is urgently needed, and need to be with early warning is simple, cost is low, by the external world
Condition influences the features such as small.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of passive rock-fall protection net automatic early-warning easy device,
Effectively to reduce the cost of passive protection net prior-warning device, reducing external environment influences to avoid reporting by mistake.
Technical scheme is as follows used by the utility model solves its technical problem：
Passive rock-fall protection net automatic early-warning easy device of the present utility model, including fixed tensioning rope and mobile tensioning
Rope, it is characterized in that：It also includes its axial proximal, axial distal end closes the sleeve to form internal cavities, is set in the internal cavities
It is equipped with elastomer, mobile link buckle, alarm and alarm actuating contact；The both ends of the elastomer respectively with mobile link buckle,
Axial proximal is fixedly connected, and fixed tensioning rope is fixedly connected with axial distal end, the front portion of mobile tensioning rope pass through axial proximal and
It is fixedly connected with mobile link buckle, alarm actuating contact is fixedly installed on close to axial proximal side.
The invention has the advantages that the alarm stress threshold values by setting elastomer, can accomplish that protection network is automatically pre-
It is alert, the cost of passive protection net prior-warning device is effectively reduced, reducing external environment influences to avoid reporting by mistake, and can realize and exempt from
Safeguard, therefore there is wide popularizing application prospect.
Brief description of the drawings
This specification includes such as next width accompanying drawing：
Fig. 1 is a kind of structural representation of passive rock-fall protection net automatic early-warning easy device of the utility model；
Component name and corresponding mark are shown in figure：Sleeve 1, elastomer 2, mobile link buckle 3, fixed tensioning rope
4th, mobile tensioning rope 5, alarm actuating contact 6, alarm 7, connecting line 8, solar panels 9.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Reference picture 1, passive rock-fall protection net automatic early-warning easy device of the present utility model, including the fixed He of tensioning rope 4
Mobile tensioning rope 5, in addition to its axial proximal, axial distal end close the sleeve 1 to form internal cavities, are set in the internal cavities
Flexible body 2, mobile link buckle 3, alarm 7 and alarm actuating contact 6.The both ends of the elastomer 2 respectively with mobile link button
Plate 3, axial proximal are fixedly connected, and fixed tensioning rope 4 is fixedly connected with axial distal end, and the front portion of mobile tensioning rope 5 is through axially
Near-end and it is fixedly connected with mobile link buckle 3, alarm actuating contact 6 is fixedly installed on close to axial proximal side.
Reference picture 1, sleeve 1 are the structure of prior-warning device, and elastomer 2 is used as stress deformation and pressure relief mechanism.Elastomer 2
Stress is compressed, and depressurization is provided for fixed tensioning rope 4, mobile tensioning rope 5.When fixed tensioning rope 4, mobile tensioning rope 5
When stress reduces, elastomer 2 extends automatically, and deformation and stress automatic adjusument, elastomer 2 repeats forced compression and stress reduces
Recover deformation, when fixed tensioning rope 4, the mobile stress of tensioning rope 5, which reach, sets threshold values, mobile link buckle 3 and alarm actuating contact 6
Contact, alarm 7 is alarmed under the connection effect of connecting line 8.Protection network automatic early-warning can be accomplished, it is passive effectively to reduce
The cost of protection network prior-warning device, reducing external environment influences to avoid reporting by mistake.
Reference picture 1, alarm actuating contact 6 are connected by connecting line 8 with alarm 7, and alarm 7 is fixedly installed on axial distal end.
Fixed setting provides the solar panel 9 of electric energy for alarm 7 on the outer wall of the sleeve 1, solves power source of alarm length
Phase sex chromosome mosaicism, and it is advantageously implemented the non-maintaining of prior-warning device.
Reference picture 1, the generally use compression spring of elastomer 2, elastic stiffness are selected according to early warning threshold values energy level.
The fixed tensioning rope 4, mobile tensioning rope 5 draw bearer cable for the opinion of passive protection net.Sleeve 1 typically uses anticorrosion square column
Shape hollow body structure, its tensile strength are not less than fixed tensioning rope 4, the 80% of the mobile tensioning intensity of tensioning rope 5.
Some of the utility model passive rock-fall protection net automatic early-warning easy device described above that simply explains through diagrams
Principle, be not intended to by the utility model be confined to shown in and described concrete structure and the scope of application in, therefore it is every it is all can
The corresponding modification that can be utilized and equivalent, belong to the apllied the scope of the claims of the utility model.
