Abstract
The invention relates to a grounding wire rack capable of alarming, which comprises a grounding wire rack. A grounding wire support plate is arranged at the bottom of the grounding wire rack, a stopping splint corresponding to the grounding wire support plate is arranged in the middle of the grounding wire rack, an elastic restoring device is arranged below the grounding wire support plate, switching nodes are arranged correspondingly on the grounding wire support plate and the stopping splint and connected with an alarm via a guide wire. By using the grounding wire rack capable of alarming, the operators cannot forget the grounding wire again on a device during power transmission operation so as to avoid accidents such as closing of a disconnecting link with the grounding wire.
Description
Technical field
The invention belongs to power industry and be used to deposit the isolated plant of construction tool, relate in particular to a kind of ground connection coil holder that can report to the police.
Background technology
Earth connection is the very general a kind of safeguard protection instrument that uses in the electric power system, is used to protect operating personnel's personal safety in construction or maintenance power failure operation, needs to take off earth connection before end-of-job send electricity.But in use,, cause the band earth connection to close disconnecting link, thereby lead to electric power accident because personnel's carelessness can be forgotten earth connection on equipment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of ground connection coil holder that can report to the police, as long as earth connection in use, be that earth connection is taken out from the shelf of depositing earth connection, depositing the shelf of earth connection will report to the police always, the prompting personnel have earth connection in use also unrecovered, after use end, being placed on the earth connection withdrawal on the shelf, no longer report to the police.
Adopt following scheme in order to solve above technical problem: comprise the ground connection coil holder, ground connection coil holder bottom is provided with the earth connection support plate, ground connection coil holder middle part is provided with the prevention clamping plate corresponding with the earth connection support plate, be provided with elasticity reset device below the earth connection support plate, earth connection support plate and prevention clamping plate are provided with corresponding switching node, and switching node is connected with alarm by lead.
Described prevention clamping plate bottom surface is provided with switching node I, and the corresponding position of earth connection support plate is provided with switching node II, and elasticity reset device is under free state, and switching node I contacts with switching node II.
Be provided with the spring of 4 symmetries below the described earth connection support plate.
Be provided with the hydraulic prop of 4 symmetries below the described earth connection support plate.
Described alarm is fixed on ground connection coil holder top.
Adopt the ground connection coil holder that can report to the police of the present invention, the operations staff does not get on to send the electricity operation with regard to can earth connection not being forgotten at equipment again, takes place thereby will avoid closing the such accident of disconnecting link with earth connection.
Description of drawings
Fig. 1 is a structural representation of the present invention:
Fig. 2 is that the A-A of Fig. 1 is to view.
Embodiment
As shown in the figure, a kind of ground connection coil holder that can report to the police, comprise ground connection coil holder 1, ground connection coil holder bottom is provided with earth connection support plate 3, ground connection coil holder middle part is provided with the prevention clamping plate 2 corresponding with the earth connection support plate, be provided with the spring 4 of 4 symmetries below the earth connection support plate 3, described prevention clamping plate 2 bottom surfaces are provided with switching node I 5a, the corresponding position of earth connection support plate is provided with switching node II 5b, elasticity reset device is under free state, switching node I contacts with switching node II, and switching node is connected with the alarm 7 that is fixed on ground connection coil holder top by lead 6.Carry storage battery or dry cell in the alarm as power supply.
Described spring also can be elasticity reset devices such as hydraulic prop.
Operation instruction, in the time of on earth connection being placed on the ground connection coil holder that the present invention can report to the police, with length of spring compressed, at this moment switching node I and switching node II open earth connection by the earth connection support plate, and alarm can not reported to the police; When using earth connection, earth connection is taken out, spring can upwards push up the earth connection support plate, at this moment switching node I contacts with switching node II, causes circuit communication, and alarm begins to report to the police, alarm is constantly emitted caution sounds such as " earth connection in use; please note withdrawal " by the chip loudspeaker, use up to earth connection and finish, till putting back to again.
