Abstract
The utility model discloses an electricity cabinet door mistake is opened power protection system, including electric cabinet door, mechanical handle, bee calling organ, mechanical handle and bee calling organ setting on the electric cabinet door, mechanical handle connect the power protection module, the power protection module is provided with three contact, machine tool system module is connected to first contact, bee calling organ is connected to the second contact, time delay power-off relay series system shutdown button are connected to the third contact. The utility model discloses can avoid operating personnel mistake to open the electric cabinet and lead to people's personal safety such as electric shock, prevent that the starting personnel maloperation from leading to lathe trouble etc. simultaneously.
Description
Technical Field
The utility model relates to a power-off protection technical field especially relates to an electric cabinet door mistake is opened power-off protection system.
Background
The electric cabinet door of lathe on the present market does not set up power-off protection module, opens by the maloperation when the electric cabinet door is careless, can appear the risk of electrocuteeing, may produce the potential safety hazard to the user. In addition, machine tool data cannot be stored in time, so that machine tool faults are caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned not enough, provide an electricity cabinet door mistake and open power protection system.
In order to achieve the above object, the technical solution of the present invention is: the utility model provides an electricity cabinet door mistake is opened power protection system, includes electric cabinet door, mechanical handle, bee calling organ, mechanical handle and bee calling organ setting on electric cabinet door, mechanical handle connect the power protection module, the power protection module is provided with first contact, second contact and third contact.
Preferably, the mechanical handle is provided with two gears.
Preferably, the power-off protection module is provided with three contacts, the first contact is connected with the machine tool system module, the second contact is connected with the buzzer, the third contact is connected with the delayed power-off relay, and the delayed power-off relay is connected with the system shutdown button in series; if the mechanical handle is in a normal closing state, the machine tool system receives a signal X00 that voltage passes through the first contact point, and the system does not have any action; if the mechanical handle is screwed to the first gear, the machine tool system receives a signal X01 that voltage passes through the second contact, the buzzer buzzes, and the system outputs an alarm; if the mechanical handle rotates to the second gear, the machine tool system receives a signal X02 that voltage passes through the third contact, the system outputs an alarm, and the main power supply is disconnected in a delayed mode.
The utility model discloses owing to adopted above technical scheme, have apparent technological effect: when the mechanical handle is screwed to the first gear, the buzzer buzzes and sends a signal X01 to the system, and the system outputs an alarm and the like; when the mechanical handle is screwed to the second stop, the coil of the delay power-off relay is electrified, the power supply of the system is turned off in a delayed mode, the main power supply is turned off at the same time, the time is used for processing and storing data by the system and sending a signal X02 to the system, the system outputs alarm and the like, personal safety such as electric shock caused by the fact that a person opens the electric cabinet is avoided, and machine tool faults caused by misoperation of a starting person are prevented.

FIG. 2 is a schematic diagram of the power-off protection module of the present invention;
FIG. 3 is a schematic diagram of the power-off button of the present invention;
description of the main reference numerals: 1. an electric cabinet door; 2. a mechanical handle; 3. a buzzer.
Detailed Description
The invention is further described with reference to the following figures and specific examples.
As shown in fig. 1-3, the utility model provides an electricity cabinet door mistake is opened power protection system, including electricity cabinet door 1, mechanical handle 2, bee calling organ 3, mechanical handle 2 and bee calling organ 3 set up 1 on the electricity cabinet door, mechanical handle 2 be provided with two fender position, mechanical handle 2 connect the power protection module, the power protection module be provided with three contact, including first contact I, second contact II and third contact III, first contact I connects machine tool system module, second contact II connects bee calling organ 3, third contact III connects time delay power off relay KT, time delay power off relay KT series system shutdown button S.
The utility model discloses an operating principle does, keeps off position SA when the mechanical handle and is in initial condition, and the mechanical handle SA is connected first contact I, and the voltage passes through first contact I sends a signal X00 and gives machine tool system, and the system does not have any action. When the gear SA of the mechanical handle is rotated to the first gear, the voltage passes through the second contact II and sends a signal X01 to a machine tool system, a buzzer P1 buzzes, and the system outputs an alarm. When mechanical handle keeps off position SA and revolves to two, the voltage passes through third contact III sends a signal X02 and gives machine tool system, and time delay outage relay KT coil circular telegram, time delay disconnection system power, and this time is used for system processing to preserve data and uses, and system output reports to the police, and time delay disconnection main power avoids personnel to open electric cabinet door 1 and leads to people's personal safety such as electrocuteeing, prevents that the start personnel maloperation from leading to lathe trouble etc. simultaneously.
The above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited to the above description, and all the equivalent changes and decorations made according to the claims of the present invention should still fall within the scope covered by the present invention.
