Abstract
The utility model discloses an electric shock caution ladder, comprising a ladder main body, a nearly electric induction device on the ladder main body and a caution device for receiving the electric shock hazard information from the nearly electric induction device and sending the caution signal. The electric shock caution ladder can give an alarm when the working range is electric or the electric value exceeds the setting range, thereby reducing the electric shock hidden trouble when using the ladder.
Description
Technical field
The utility model relates to a kind of electric shock caution ladder.
Background technology
The user sometimes can be erected at charging zone with ladder when using ladder, as when ascending a height, eminence is the live wire net often, is easy to touching because of carelessness; When especially the electrician used ladder, in order to keep in repair charging equipment, ladder usually all was erected at electric wire, electrical equipment next door.In order to reduce the generation of electric shock time; the user that electrician etc. are relevant with the electricity operation usually uses the protection against electric shock insulating ladder with insulation protection effect to replace common aluminium alloys ladder; but these insulating ladders also can only have the protection against electric shock effect in certain current value range; after current/voltage arrived above setting value greatly, the use of this protection against electric shock insulating ladder also can be no longer safe.If ladder is provided with the electric shock alarming device, when electric current or electric current were arranged near ladder greater than certain value, the electric shock alarming device can be reported to the police automatically, reminded to make the user note Danger Electric shock risk, then can improve greatly and use terraced safety.
Summary of the invention
The utility model purpose is: a kind of electric shock caution ladder is provided, and whether it can report to the police to having electricity or electricity value whether to surpass setting range in the working range, thereby reduces the electric shock hidden danger of user when using ladder.
The technical solution of the utility model is: a kind of electric shock caution ladder, comprise the ladder body, and described ladder body is provided with nearly electrical induction device and receives Danger Electric shock risk information that nearly electrical induction device sends and the alarming device that sends alarm signal.
For the common ladder that does not have the insulation protection function; nearly electrical induction device is sensed when having electric current to pass through in the working range; then send Danger Electric shock risk information to alarming device; alarming device then is activated and sends information warning; informing in the user job scope has Danger Electric shock risk, gets an electric shock when avoiding the user to ascend a height.
For having protection against electric shock insulation ladder, except to having electric current reports to the police, nearly electrical induction device the working range internal induction to the degree of protection setting value of current value and insulation ladder compare, when the current value of sensing greater than when setting value, surpass the scope Danger Electric shock risk and warn.
Further, in above-mentioned electric shock caution ladder, described nearly electrical induction device is installed in the top of described ladder main body.Often be positioned at eminence because have the position of Danger Electric shock risk, a plurality of nearly electrical induction devices can certainly be set in a plurality of positions of ladder main body.
Further, in above-mentioned electric shock caution ladder, described alarming device is a buzzer.After receiving the Danger Electric shock risk information that nearly electrical induction device sends, buzzer is sounded a buzzer, and the user is away from this zone operation in caution.Certainly, except buzzer, alarming device can also be other audio signal, as the recording of playing Danger Electric shock risk etc.
Further, in above-mentioned electric shock caution ladder, described alarming device is the LED lamp that is arranged on the ladder body surface.Certainly other lamp also can be used in here, but LED lamp brightness height, power consumption are little, are the caution light sources that is fit to more.After receiving the Danger Electric shock risk information that nearly electrical induction device sends, the LED lamp is warned user's ladder and is sitting in the Danger Electric shock risk zone by brightening, glimmer or can being to be aligned to behind the Word message shinnyly.
Preferable, to state in the caution ladder that gets an electric shock above-mentioned, described LED lamp is arranged on the surface toward the outer side of ladder body, the easier position of being seen by the user.
Certainly, described alarming device also can be the acousto-optic warning device with buzzer and the combination of LED lamp, perhaps other other alarming devices of being discovered by people easily.
The utility model has the advantages that:
1. the utility model is provided with the electric shock alarming device on ladder, makes to be erected at ladder to have the Danger Electric shock risk zone and the time can send the Danger Electric shock risk caution, and the Danger Electric shock risk when reducing the user with ladder takes place.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the Facad structure schematic diagram of the utility model specific embodiment one;
Fig. 2 is the side structure schematic diagram of the utility model specific embodiment one;
Fig. 3 is the Facad structure schematic diagram of the utility model specific embodiment two;
Fig. 4 is the side structure schematic diagram of the utility model specific embodiment two.
Wherein: 1 ladder body; 2 nearly electrical induction devices; 31 buzzers; The 32LED lamp.
The specific embodiment
Specific embodiment one:
As depicted in figs. 1 and 2, a kind of electric shock caution ladder comprises ladder body 1, and described ladder body 1 is provided with nearly electrical induction device 2 (electroscope) and receives Danger Electric shock risk information that nearly electrical induction device 2 sends and the alarming device that sends alarm signal.Wherein near electrical induction device 2 is installed on the ladder body 1 top step.
Described alarming device is the buzzer 31 that is installed on the ladder body 1.
Specific embodiment two:
As shown in Figure 3 and Figure 4, other structure of present embodiment is identical with specific embodiment one, but described alarming device is the LED lamp 32 that is arranged on ladder body 1 surface.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
