Abstract
An intelligent protection device for a coupler comprises a display control box, a temperature sensor, a carbon brush and a relay switch. The temperature sensor is fixed to the coupler. When the surface temperature of the coupler is higher than a set value, the relay switch is disconnected under the control of the display control box, and power of a motor is cut off. When the surface temperature of the coupler is lower than the set value, the relay switch is connected, and the power of the motor is connected. Thus, the purpose of protecting the coupler is achieved.
Description
Technical field
The present invention relates to a kind of intelligent protection device, specifically, relate to a kind of coupling device intelligent protection device.
Background technology
For make to automatically terminate and be connected when motor automatically engages, overloads when starting with reductor, the electromechanical equipments such as mining scraper machine, ribbon conveyer adopt coupling device more.At present, the coupling device of main flow has fluid-flywheel clutch or friction clutch.These coupling devices all adopt mechanical technique, do not possess intelligent.Market demand is a kind of can show clutch surface temperature in real time, and the coupling device protective device of Based Intelligent Control motor.
Summary of the invention
The object of the invention is: a kind of coupling device intelligent protection device is provided, can shows in real time coupling device surface temperature range, and according to unlatching and the disconnection of coupling device surface temperature automatic control motor, realize the defencive function to coupling device.
Technical scheme of the present invention is:
An intelligent protection device, comprises and shows control box, temperature sensor, carbon brush and relay switch.Wherein, show that control box is core component of the present invention, according to the connecting and disconnecting of thermorelay switch; Temperature sensor is for perception coupling device surface temperature; Carbon brush is for connecting power supply circuits to temperature sensor; Relay switch is for the mains switch of motor.
Further, show that control box comprises Single Chip Microcomputer (SCM) system, temperature sampling circuit, display control circuit, LED lamp, buzzer and ON-OFF control circuit.Wherein, Single Chip Microcomputer (SCM) system is control centre, reception is from the signal of temperature sampling circuit, by the real-time displays temperature scope of LED lamp, by buzzer, send heat alert information, when temperature is during higher than set point, by ON-OFF control circuit relay switch in good time, when temperature is during lower than set point, by ON-OFF control circuit engage relay switch.
The invention has the beneficial effects as follows:
1. criterion is clear and definite.Country's peace mark regulation, the clutch surface temperature of using under coal mine must not surpass 200 ± 2 ℃, and collecting temperature of the present invention, from coupling device surface, is strictly carried out by national standard.
2. protected mode is compound.The present invention adopts demonstration, two kinds of modes of buzzing to point out coupling device surface temperature, makes operating personnel monitor at any time coupler rotor state.
3. protection is timely, startup is rapid.The present invention adopts single-chip microcomputer process temperature information, adopts relay switch as electric power switch, is switched on or switched off the time used all at Millisecond, and protection and startup are in time.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present invention.
Fig. 2 is the theory diagram of demonstration control box of the present invention.
Embodiment
As shown in Figure 1, a kind of coupling device intelligent protection device, comprises and shows control box, temperature sensor, carbon brush and relay switch.Wherein, show that control box is core component of the present invention, according to the connecting and disconnecting of thermorelay switch; Temperature sensor is fixed on coupling device, for perception coupling device surface temperature; Carbon brush is for connecting power supply circuits to temperature sensor; Relay switch is for the mains switch of motor.
As shown in Figure 2, show that control box comprises Single Chip Microcomputer (SCM) system, temperature sampling circuit, display control circuit, LED lamp, buzzer and ON-OFF control circuit.Wherein, Single Chip Microcomputer (SCM) system is control centre, reception is from the signal of temperature sampling circuit, by the real-time displays temperature scope of LED lamp, by buzzer, send heat alert information, when temperature is during higher than set point, by ON-OFF control circuit relay switch in good time, when temperature is during lower than set point, by ON-OFF control circuit engage relay switch.
LED lamp is one group totally 5, in temperature, is between 160 to 200 ℃, and 10 ℃ of the every increases of temperature, light a lamp.
Buzzer warning value is made as 180 ℃, when temperature is during higher than this setting, and buzzer warning.
