Description
Technical Field
The utility model relates to the field of monorail crane equipment, in particular to an intelligent charging control system for an underground monorail crane.
Background
A DX series explosion-proof storage battery electric traction monorail crane locomotive is coal mine underground auxiliary transportation equipment which takes a storage battery as a power source and drives a motor to operate by electric power. The storage battery is overcharged to result in the life-span to reduce, and the storage battery is insufficient to cause the equipment to crash. And in the charging process of the storage battery, harmful gases such as fog acid and hydrogen are also released to cause the alarm of the carbon monoxide sensor under the coal mine.
SUMMERY OF THE UTILITY MODEL
The utility model provides an underground monorail crane intelligent charging control system, which aims to solve the problems that in the prior art, a monorail crane storage battery is overcharged, and harmful gas is released in the charging process to cause the alarm of a carbon monoxide sensor.
The technical scheme of the utility model is realized as follows:
an intelligent charging control system of a downhole monorail crane comprises: the device comprises a PLC, a voltage detection element, a carbon monoxide sensor, a remote power-off device, a control relay and a charger, wherein the PLC is connected with the control relay, the control relay is connected with a charging switch of the charger, one connecting end of the voltage detection element is connected with the PLC, the other connecting end of the voltage detection element is connected with the charger, the carbon monoxide sensor is connected with the remote power-off device, and the remote power-off device is connected with the PLC.
Preferably, the PLC controller is connected with a manual switch.
Preferably, the concentration limit value of the carbon monoxide in the PLC is lower than the normal carbon monoxide concentration alarm value.
The utility model has the beneficial effects that: according to the underground monorail crane intelligent charging control system, harmful gas can be generated when a storage battery is charged, the carbon monoxide sensor detects the harmful gas, the PLC controller cuts off a charging switch of the charger when the carbon monoxide sensor detects that the concentration of carbon monoxide reaches a certain numerical value, and the PLC controls to turn on the charging switch of the charger when the concentration of carbon monoxide is reduced to a certain numerical value. When the storage battery is charged, the carbon monoxide sensor under the mine gives a false alarm, and the phenomenon that the storage battery is overcharged or over-deficient is avoided.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural diagram of an intelligent charging control system of an underground monorail crane.
In the figure:
1. a PLC controller; 2. a voltage detection element; 3. a carbon monoxide sensor; 4. a remote power-off device; 5. controlling the relay; 6. a charger; 7. and (4) a manual switch.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example (b): as shown in fig. 1, an intelligent charging control system for a downhole monorail crane comprises: PLC controller 1, voltage detection component 2, carbon monoxide sensor 3, remote power-off device 4, control relay 5 and machine 6 charges, PLC controller 1 connection control relay 5, and control relay 5 connects the switch that charges of machine, and PLC controller is connected to a link of voltage detection component 2, and the machine that charges is connected to another link, and remote power-off device 4 is connected to carbon monoxide sensor 3, and remote power-off device 4 connects PLC controller 1. The PLC controller is connected with a manual switch 7. The manual switch can independently control the PLC controller.
The storage battery can produce harmful gas when charging, and the carbon monoxide sensor detects harmful gas, and after the carbon monoxide sensor detected the concentration of carbon monoxide and reached certain numerical value, the PLC controller can cut off the switch that charges of machine, and after the concentration of carbon monoxide reduced to certain numerical value, PLC control opened the switch that charges of machine. The voltage detection unit detects the voltage of the charger, when the charging voltage reaches a set value, the PLC controller enables the control relay to be attracted, the normally closed point of the control relay is disconnected, and the charger is not charged any more. And if the charging voltage does not reach the set value, continuing charging.
The limiting value of the concentration of the carbon monoxide in the controller is lower than the normal alarm value of the concentration of the carbon monoxide, at the moment, the charger is closed, and harmful gas generated by the storage battery is emitted, so that false alarm of the concentration of the carbon monoxide in the underground coal mine is avoided. And when the concentration of the carbon monoxide is reduced, the PLC opens the charger to continue charging. And overshoot or over deficit can be avoided while avoiding false carbon monoxide alarm.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
