Abstract
The invention discloses a close-distance safety reminding device of an electrical cabinet, comprising a distance detection sensor for detecting the distance between a moving object and a high-voltage charged body, a sensor signal processing unit for processing signals from the distance detection sensor and outputting control signals outwards and an alarm unit for outputting alarm signals outwards, wherein the signals output by the distance detection sensor are connected with the sensor signal processing unit; the signals output by the sensor signal processing unit are connected with the alarm unit; and a power supply unit is connected with the sensor signal processing unit and the alarm unit respectively. The close-range safety reminding device can detect the close-distance state between the moving object and the high-voltage charged body, sends the alarm signals for reminding in real time, reduces the electric shock hidden dangers and guarantees the safe running of the electrical cabinet.
Description
Technical Field
The invention relates to a close-range safety reminding device for an electric control cabinet.
Background
The electric components of electric cabinet internally mounted are various, and some electric components are connected to the high-voltage incoming line end that enters into the electric cabinet, if: high-voltage electric control cabinet. There is a possibility that the low voltage is changed into the high voltage by processing of the internal circuit, such as: high-voltage dust removal device, step-up transformer, etc.
When people work in the electric control cabinet, the incoming line switch or the breaker entering the electric control cabinet is cut off for safety. Sometimes, one may forget to switch off the switch or circuit breaker, or intentionally do so with power, which is generally not problematic if the safety measures are properly protected.
However, particular attention should be paid at this time to: tools used by operators or the bodies of the operators must be kept at a certain distance from the exposed charged bodies to meet the requirements of safety protection. When a person is busy, attention may be distracted, and therefore, the person may forget to use a tool or may have his body in too close proximity to a bare charged body, particularly a high voltage charged body. Therefore, there is a need for a device capable of reminding a moving object approaching a high-voltage charged object in a short distance, and unfortunately, the existing electric control cabinet does not have such a device.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the close-range safety reminding device for the electric control cabinet, which can detect the close-range state of a moving object and a high-voltage electrified object and can send out an alarm signal in time.
The technical scheme of the invention is as follows:
closely safe reminding device of automatically controlled cabinet, its characterized in that: comprises a distance detection sensor for detecting the distance between a moving object and a high-voltage charged object; the sensor signal processing unit is used for processing the signal of the distance detection sensor and outputting a control signal to the outside; the alarm unit is used for outputting an alarm signal to the outside; the output signal of the distance detection sensor is connected to the sensor signal processing unit, the output signal of the sensor signal processing unit is connected to the alarm unit, and the power supply unit is connected with the sensor signal processing unit and the alarm unit respectively.
The distance detection sensor can be an ultrasonic distance measurement sensor or an infrared distance measurement sensor.
Further, the alarm unit is a sound device or a light device, and preferably, the alarm unit is a sound and light integrated device.
The invention has the following good technical effects:
the invention can detect the close range state of the moving object and the high-voltage charged object, and can send out an alarm signal in time to remind, thereby reducing the hidden danger of electric shock and providing guarantee for the safe operation of the electric control cabinet.
Drawings
The invention is further described below with reference to the figures and examples.
The figure is a schematic block diagram of an embodiment of the present invention.
In the figure: 1. the device comprises a distance detection sensor 2, a sensor signal processing unit 3, an alarm unit 4 and a power supply unit.
Detailed Description
Referring to the attached drawings, the close-range safety reminding device of the electric control cabinet comprises a distance detection sensor 1, a sensor signal processing unit 2, an alarm unit 3 and a power supply unit 4. The output signal of the distance detection sensor 1 is connected to the sensor signal processing unit 2, the output signal of the sensor signal processing unit 2 is connected to the alarm unit 3, and the power supply unit 4 is respectively connected with the sensor signal processing unit 2 and the alarm unit 3.
The distance detection sensor 1 is installed at a charged body which is easily touched by the human body or a tool in the electric control cabinet, in particular to a high-voltage and exposed charged body. These places cannot be in live contact and need to be reminded to the operator.
An ultrasonic sensor composed of a piezoelectric transducer device can be used for measuring distance. The transmission and reception of the infrared sensor can be converted into a measurement of the distance. Therefore, the distance detection sensor 1 may use an ultrasonic ranging sensor or an infrared ranging sensor.
The power supply unit 4 can use the commercial power in the electric control cabinet, and for safety, the commercial power can be transformed into low-voltage safe voltage.
