The beneficial effects are that, through a PLC control system, the detection platform can realize height adjustment while automatically tracking coal layer height changes; and coal layer surface parameters measured by the sensors on the detection platform are emitted to a wireless receiving apparatus of the PLC control system through the wireless emitting device on the detection platform, detection data is collected and displayed by the PLC control system through the wireless receiving apparatus, and therefore measurement parameters are close to real values.
Description
Technical field
The utility model relates to a kind of dump automatic tracking, monitoring protective device, and this device can carry out height control from motion tracking coal seam height change by the PLC control system.
Background technology
In recent years, along with industrial expansion, particularly each large thermal power plant and coalification mill coat are in great demand, various large-scale closed coal stores also occur thereupon, owing to large-scale coal store generally all is the tall and big and substantially relatively sealing of warehouse, so the comprehensive monitoring of various potential safety hazards has just become big problem in the coal store, makes that the dump safety monitoring of large-scale closed storage warehouse is more and more important.Tradition coal store dump safety detecting system, various sensors are lifting and coal store top just, and dump is distant in the storehouse, can't truly measure the various parameter values on dump surface, and traditional measurement means all the sensors all be the fixed installation, sensing range is limited, limitation is bigger.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art; the utility model provides a kind of dump automatic tracking, monitoring protective device; detection platform can be carried out height control from motion tracking dump height change by the PLC control system; and by wireless launcher on the detection platform coal store safe operation important parameter is emitted on the detection platform; the PLC control system is gathered demonstration by radio receiver detecting data; and the signal and the master system that receive are shared assurance coal store reliability service.
The utility model is realized with following technical scheme: this installs by the PLC control system, detection platform, guide piece, speed change gear, motor, cord winder and warning system are formed, temperature sensor is housed on the detection platform, carbon monoxide transducer, combustible gas sensor, wireless launcher and tilt switch, and detection platform top links to each other with the fixing hoisting rope of shift fork one end, the hoisting rope other end is by the lower shoe place fixedly behind the guide piece of one stroke upper limit switch, be wrapped on the cord winder, the PLC control system receives the temperature signal that the wireless launcher of the inner detection platform of coal store transmits by the internal wireless receiver, the carbonomonoxide concentration signal, thereby combustable gas concentration signal starter motor drives the landing of speed change gear control platform, and passes to master system detecting numerical value by RS485.It further is: a tilt switch is installed in the detection platform bottom, after the tendency switch is run into the coal of coal store, tilt switch is connected, motor shuts down, when the coal position descends, it is vertical that tilt switch will keep again, motor will start again, transfer detection platform, after tilt switch is run into the coal seam, just can stop operating, arrange a wireless launcher on the detection platform base plate, launch gathering the sensor signal of coming, the hoisting rope that promotes and transfer detection platform must pass through guide piece, and guide piece has two angle sheaves, is divided into angle sheave and following angle sheave.
Beneficial effect is: detection platform can be carried out height control from motion tracking coal seam height change by the PLC control system, and be transmitted to PLC control system radio receiver by the coal seam surface parameter that wireless launcher on the detection platform is measured the detection platform upper sensor, the PLC control system is gathered demonstration by wireless receiver detecting data, makes measurement parameter more near actual value.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model work structuring synoptic diagram;
Fig. 2 is the utility model system principle diagram;
Among the figure: 1, motor, 2, speed change gear, 3, cord winder, 4, hoisting rope, 5, guide piece, 6, stroke upper limit switch, 7, shift fork, 8, detection platform, 9 temperature sensors, 10, carbon monoxide transducer, 11, tilt switch, 12, combustible gas sensor, 13, wireless launcher.
Embodiment
As shown in Figure 1, a kind of dump automatic tracking, monitoring protective device, this device is made up of PLC control system, detection platform, guide piece, speed change gear, motor, cord winder and warning system.The PLC control system receives the temperature signal that the wireless launcher stretch into the inner detection platform of coal store transmits by the internal wireless receiving trap, the carbonomonoxide concentration signal, start and stop and rotating that combustable gas concentration signal and tilt switch signal are controlled motor drive the running of speed change gear main drive shaft, main drive shaft drives the cord winder running be contained on the driven shaft after by gear change, hoisting rope is by on the guide piece, be connected with detection platform behind the following angle sheave, thereby realize rising and the decline of detection platform, the PLC control system can show the detection data on the spot, and passes to master system detecting numerical value by RS485.
The course of work: carbon monoxide transducer is installed on the detection platform, combustible gas sensor, each one of temperature sensor and tilt switch, the signal that detects inserts wireless launcher, the signal that wireless launcher receives sensor is transmitted to the radio receiver of PLC control system, the PLC control system shows on the spot to receiving the data of coming, again by PLC control system design temperature upper limit alarm value, CO concentration is alarming value just, the high alarming value of CO concentration, the data that the first alarming value of combustable gas concentration and the high alarming value of combustable gas concentration and sensor detect compare, when a certain numerical value surpasses warning, can start warning system, send the sound and light alarm prompting.When a certain numerical value surpasses high the warning, automatic starter motor main story is upwards promoted detection platform, run into the stroke upper limit switch that is fixed on the angle sheave lower shoe up to the shift fork that is fixed on the hoisting rope, system stops to promote, up to high alarm release, PLC control system automatic starter motor counter-rotating is again transferred detection platform, the coal in tilt switch is run into coal store, and system stops to transfer.The lifting of system and to transfer be that start and stop and rotating by PLC control system control motor drives the running of speed change gear main drive shaft, main drive shaft drives the cord winder running be contained on the driven shaft after by gear change, realizes the lifting of detection platform and transfers thereby drive by the hoisting rope of guide piece.
The PLC control system is transferred to host computer to data monitored by RS485; by master system temperature, CO concentration and combustable gas concentration change curve are simulated out; when surpassing alarming value, a certain numerical value can jump out the current alarm content of host computer warning interface display; and simulate the realistic animations effect that a kind of dump automatic tracking, monitoring protective device rises and descends at master system, can get information about on-the-spot equipment running status by the pulpit.
