Utility model content
The deficiency that the utility model exists for prior art just, provides a kind of overhead ground wire suspension clamp, when there is overhead ground wire suspension clamp damage, can more be conducive to power grid maintenance and upkeep operation personnel find in time.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of overhead ground wire suspension clamp, comprise: hull, hanger, described hanger is connected in the middle part of described hull by rotating shaft, on described hanger, be provided with warning device, described warning device comprises induction part, warning part and is controlled break-make and for making the warning circuit of described warning part work, when described hull deflects, can be contacted described induction part by described induction part.
Improvement as technique scheme, described induction part comprises having the outer tube of blind hole and be fixedly arranged on the rod-like members on described hanger, described outer tube is two and is set with the two ends in described rod-like members, and is provided with elastomer between the blind hole end wall of the end of described rod-like members and described outer tube.
Improvement as technique scheme, described warning circuit comprises power supply, connects two static contacts of described power supply positive and negative electrode and for connecting the movable contact spring of two described static contacts, described power supply, described warning part, two described movable contact springs and described static contact are connected mutually respectively.
As the improvement of technique scheme, described movable contact spring is arranged on described outer tube, and described static contact is arranged in described rod-like members.
As the improvement of technique scheme, described warning part is equipment that can be luminous, equipment that can sounding, the equipment that maybe can transmit.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
A kind of overhead ground wire suspension clamp described in the utility model, when indivedual overhead ground wire suspension clamp damage, adjacent overhead ground wire suspension clamp can be warned power grid maintenance and upkeep operation personnel by luminous, sounding or the mode of sending signal, make it to find in time the damage of overhead ground wire suspension clamp, thereby the situation of avoiding overhead ground wire suspension clamp in blocks to damage occurs.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of a kind of overhead ground wire suspension clamp described in the utility model;
Fig. 2 is a kind of overhead ground wire suspension clamp side-looking structural representation described in the utility model;
Structural representation when Fig. 3 is a kind of overhead ground wire suspension clamp deflection described in the utility model;
Fig. 4 is warning device structural representation described in the utility model.
Embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figures 1 to 4, be a kind of overhead ground wire suspension clamp structural representation described in the utility model.A kind of overhead ground wire suspension clamp described in the utility model, comprise: hull 1, hanger 2, described hanger 2 is connected in the middle part of described hull 1 by rotating shaft 3, on described hanger 2, be provided with warning device 4, described warning device 4 comprises induction part 41, warning part 42 and is controlled break-make and for making the warning circuit of described warning part 42 work, when described hull 1 deflects, can be contacted described induction part 41 by described induction part 41.Particularly, described induction part 41 comprises having the outer tube 411 of blind hole and be fixedly arranged on the rod-like members 412 on described hanger 2, described outer tube 411 is two and is set with in the two ends of described rod-like members 412, and is provided with elastomer 413 between the end of described rod-like members 412 and the blind hole end wall of described outer tube 411.Further, described warning circuit comprises power supply 43, connects two static contacts 44 of described power supply 43 positive and negative electrodes and for connecting the movable contact spring 45 of two described static contacts 44 respectively, and described power supply 43, described warning part 42, two described movable contact springs 45 and described static contact 44 are connected mutually.Further, described movable contact spring 45 is arranged on described outer tube 411, and described static contact 44 is arranged in described rod-like members 412.Particularly, described warning part 42 is equipment that can be luminous, equipment that can sounding, the equipment that maybe can transmit.
As shown in Figure 1, under normal condition, under elastomer 413 effect, blind hole end wall and the described rod-like members 412 of outer tube 411 have longer distance, thereby make between two static contacts 44 in off state, and warning part 42 is not worked.When indivedual overhead ground wire suspension clamp damage, because variation has occurred overhead ground wire local height, make the hull 1 of the adjacent overhead ground wire suspension clamp in overhead ground wire suspension clamp both sides of damage produce deflection, as shown in Figure 3, thereby make movable contact spring 45 connect two static contacts 44, warning circuit is started working warning part 42; Particularly, as shown in figures 1 and 3, in order to make the alarming effect of warning device 4 better, in hanger 2 both sides, be respectively provided with a warning part 42, and be provided with the break-make controlling organization of two warning circuits---i.e. two groups of movable contact springs that cooperatively interact 45 and static contact 44, correspond respectively to two outer tubes 411, no matter when hull 1 is deflection left or deflection to the right, can both make warning circuit be switched on.
Particularly, described warning part 42 refers to that for can luminous equipment referring to bulb, equipment that can sounding loudspeaker, the equipment that maybe can transmit refer to the sender unit of fixed frequency, can be more specifically radio signal launcher, as the oscillating circuit of emitting electromagnetic wave.
Above content is the detailed description of in conjunction with specific embodiments the utility model being done, and can not assert that the concrete enforcement of the utility model only limits to these explanations.For the utility model person of ordinary skill in the field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to the scope of the utility model protection.
