Invention content
It is an object of the invention to overcome disadvantages described above, a kind of bolt anti-fall device simple in structure, safe and reliable is provided.
To achieve the above object, the technical solution adopted by the present invention is:A kind of bolt anti-fall device comprising bolt protects Cover, signal conductor, the screw rod of the bolt pair pass through the through-hole on table top in bolt shield, table lower part card in the bolt shield In the nut appearance of bolt pair, the signal conductor is attached to the surface of adjacent bolt shield and is serially connected to form one successively A closed loop is connected with fan monitoring system, and when signal conductor disconnects, fan monitoring system sends out bolt abnormal alarm.
Preferably, the material of the bolt shield is the elastic material of insulation.
Preferably, the signal conductor is in bolt shield.
Preferably, the both sides of the bolt shield are equipped with primary and secondary bell and spigot joint, and the sub-set end of the primary and secondary bell and spigot joint is that nothing is stretched Contracting, inside set signal conductor connector;The mother set end of the primary and secondary bell and spigot joint is the casing of retractility, and mother set end end is equipped with One end of signal conductor external part, signal conductor is connected with signal conductor connector, and the other end of signal conductor passes through master-slave casing The mother set end of connector is connected with the external part of signal conductor, and the external part of signal conductor is inserted into the connector of adjacent signals conducting wire Interior, signal conductor is sequentially connected in series and forms a closed loop to be connected with fan monitoring system.
Preferably, in order to improve the intensity of master-slave casing connection, master-slave casing is buckle structure.
Preferably, in order to ensure signal sensitivity, the connector and external part of signal conductor are earphone plug in construction, and The depth of insertion is no more than 5mm.
The method have the benefit that:Shield is mounted on the nut tightened, then head and the tail connection communication wire portion Point, the bolt group of flange face entire in this way forms a circuit, then in the remote monitoring system for accessing wind turbine itself.Such as bolt pine Dynamic or bolt, which is fallen, can all make communication conductor interrupt, remote monitoring system can and alarm.And be broken bolt due to The Hoop exercising apparatus ring of shield is connected, and will not fall and cause secondary damage.The structure of the device is simple, of low cost, is easy dimension Shield.Manpower inspection trips are avoided, maintenance levels is substantially increased.
Description of the drawings
Fig. 1 is structural schematic diagram of the embodiment of the present invention;
Fig. 2 connection diagrams between adjacent bolt pair of the embodiment of the present invention;
Fig. 3 is operating diagram of the embodiment of the present invention.
Specific implementation mode
Below in conjunction with attached drawing, the present invention will be further described.
With reference to attached drawing, a kind of bolt anti-fall device comprising bolt shield 1, signal conductor 2, the screw rod 3 of the bolt pair The through-hole on table top in bolt shield 1, table lower part is stuck in 4 appearance of nut of bolt pair, the letter in the bolt shield 1 Number conducting wire 2 is attached to the surface of adjacent bolt shield 1 and is serially connected to form a closed loop and fan monitoring system phase successively Connection, when signal conductor 2 disconnects, fan monitoring system sends out bolt abnormal alarm, and the material of the bolt shield 1 is insulation Elastic material, the signal conductor 2 is in the bolt shield 1, and the both sides of the bolt shield 1 are equipped with primary and secondary bell and spigot joint, The sub-set end 1-1 of the primary and secondary bell and spigot joint is inductility, inside sets 2 connector of signal conductor;The mother of the primary and secondary bell and spigot joint The casing that end 1-2 is retractility is covered, the mother set end ends 1-2 are equipped with 2 external part of signal conductor, one end of signal conductor 2 and signal 2 connector of conducting wire is connected, and the other end of signal conductor 2 passes through the external part phase of the mother set end 1-2 and signal conductor 2 of retractility Even, the external part of signal conductor 2 is inserted into the connector of adjacent signals conducting wire 2, and signal conductor 2 is sequentially connected in series and forms one and closes Ring is connected with fan monitoring system, and in order to improve the intensity of master-slave casing connection, master-slave casing is buckle structure, in order to ensure signal Sensitivity, the connector and external part of signal conductor 2 are earphone plug in construction, and the depth being inserted into is no more than 5mm.
The course of work of the embodiment of the present invention is sleeved on whole ring nut 4 by shield 1, and connection signal conducting wire 2 is allowed to be formed One closed loop.The terminal of closed loop can all be made in communication signal conducting wire 2 as bolt looseness or bolt are fallen by computer monitor Disconnected, remote port can be forecast in time.And the bolt being broken will not fall since the Hoop exercising apparatus ring of shield 1 is connected and cause two Secondary damage.The structure of the device is simple, of low cost, is easy to safeguard.Manpower inspection trips are avoided, substantially increases and safeguards water It is flat.
