Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
According to the earth connection of the embodiment of the present invention, as shown in Figure 1 or 2, comprising: earth connection body 10 and suggestion device 20; Suggestion device 20 is arranged on earth connection body 10, for sending cue when earth connection body 10 is articulated on grounding apparatus.
Apply the earth connection of technical scheme of the present invention, by earth connection body 10 arranges suggestion device 20, this suggestion device 20 is for sending cue when earth connection body 10 is articulated on grounding apparatus, thus prompting operation maintenance personnel removes the earth connection in power failure equipments before starting power transmission after carrying out sealing hanging earthing conductor operation to power failure equipments night, start power transmission under avoiding occurring in Grounding, cause very serious security incident.Solve the earth connection in prior art, power failure equipments being sealed extension and be difficult to be observed the technical problem causing line power transmission with ground at night.
During concrete enforcement, as shown in Figure 1 or 2, suggestion device 20 comprises: position switch 21, power supply 22 and Tip element 23; Tip element 23 is connected with power supply 22 by position switch 21, position switch 21 for when earth connection body 10 is in vertical state by Tip element 23 and power supply 22 conducting, make Tip element 23 send cue.Particularly, position switch 21 comprises: chute 211, first predeterminated position of chute 211 has the first conductor plate 212 and is connected with power supply 22 with the second conductor plate 213, first conductor plate 212 that the first conductor plate 212 is oppositely arranged, and the second conductor plate 213 is connected with Tip element 23, Metal Ball 214 is rollably arranged in chute 211, as shown in Figure 2, when earth connection body 10 is in vertical state, namely when earth connection body 10 is articulated on grounding apparatus, Metal Ball 214 be rolled into the first predeterminated position by the first conductor plate 212 and with the second conductor plate 213 conducting, thus make Tip element 23 and power supply 22 conducting, Tip element 23 continues to send cue, enable operation maintenance personnel in night observation to the earth connection be articulated in power failure equipments, thus after operation terminates, point out the earth connection of operation maintenance personnel starting to remove before power transmission in power failure equipments, power transmission is started under avoiding occurring in Grounding.
In order to ensure that earth connection is from when grounding apparatus is pulled down, Tip element 23 and power supply 22 can disconnect by position switch 21 in time, prevent Tip element 23 from after pulling down, sending cue always, waste power supply 22 electricity.Second predeterminated position of chute 211 has the first non-conductor plate 215 and the second non-conductor plate 216 relative with the first non-conductor plate 215, wherein, first non-conductor plate 215 is connected with the first conductor plate 212, second non-conductor plate 216 is connected with the second conductor plate 213, chute 211 is dovetail groove, first predeterminated position is near the upper base of dovetail groove, second predeterminated position is near the bottom of dovetail groove, Metal Ball 214 can Free-rolling in dovetail groove, as shown in Figure 2, when earth connection body 10 is in vertical state, Metal Ball 214 under gravity, be rolled into the first predeterminated position by the first conductor plate 212 and with the second conductor plate 213 conducting, thus make Tip element 23 and power supply 22 conducting, as shown in Figure 1, when earth connection body 10 is in level, Metal Ball 214 is rolled the second predeterminated position, namely the position between the first non-conductor plate 215 and the second non-conductor plate 216 is rolled into, the end of the second predeterminated position of chute 211 has baffles 217, and baffles 217 can be used in restriction Metal Ball 214 and skids off from chute 211, now, first conductor plate 212 and disconnecting with the second conductor plate 213, thus Tip element 23 and power supply 22 are disconnected.Therefore, operation maintenance personnel by earth connection from when pulling down until grounding apparatus, only earth connection need be lain in relevant position can just Tip element 23 and power supply 22 disconnect, and power supply 22 electricity of avoiding waste, uses very simple.
Tip element 23 one of can select loudspeaker or luminescent device at least as required, and particularly, loudspeaker can be buzzer, and luminescent device can be LED photoflash lamp.LED photoflash lamp can be used alone to reach at night points out effect preferably, although buzzer also can reach point out the effect of operation maintenance personnel at night, preferably with LED photoflash lamp with the use of, point out effect better.
Generally, daytime is after grounding apparatus mounts earth connection, operation maintenance personnel can both be observed, suggestion device 20 can not be needed to work, in order to reduce the waste of power supply 22, as shown in figure 3 or 4, suggestion device 20 also comprises photo resistance 24, photo resistance 24 is arranged between power supply 22 and position switch 21 or between position switch 21 and Tip element 23, photo resistance 24 needs light secretly could start work to a certain extent, therefore, when using earth connection by day, the circuit not conducting of suggestion device 20, effectively reduces the waste of power supply 22 electricity.
Earth connection is in the long-time not used time, make the circuit of suggestion device 20 to conducting to prevent the change of earth connection position, as shown in Figure 3, suggestion device 20 also comprises: main switch 25, main switch 25 is arranged between power supply 22 and position switch 21, and main switch 25 is closed when not using by earth connection, even if earth connection position changes, suggestion device 20 also can not work, and avoids the unnecessary waste of power supply 22.Before earth connection uses, only need in advance main switch 25 to be opened.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
