Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to safety monitoring technical field, concretely relates to a coal mine stockyard safety monitoring equipment. BACKGROUND
[0002] At present, domestic thermal power plants, coal chemical plants mostly adopt coal stockyard to store coal, but with the storage time of coal increasing, the coal will be heated, and then spontaneous combustion is caused, and even combustible gas is produced due to the spontaneous combustion of the coal, leading to explosion. In order to prevent such situation, it is necessary to use monitoring equipment to monitor and manage the stockyard daily.
[0003] However, some existing coal pile monitoring equipment is relatively simple, and it is difficult to realize full-range monitoring, and frequent manual inspection is required, and the monitoring effect is poor. CONTENT OF UTILITY MODEL
[0004] The utility model discloses a coal mine stockyard safety monitoring equipment.
[0005] The utility model is through following technical scheme realizes: a coal mine stockyard safety monitoring equipment, including base, be equipped with stand on base, its characterized in that, the top of stand is equipped with monitoring platform, is equipped with holder on monitoring platform, is equipped with visible light camera and infrared detector on holder, be equipped with fixing frame on the side above stand, is equipped with air monitoring appearance on fixing frame, be equipped with control box below stand, be equipped with display, temperature sensor and controller in control box, be equipped with alarm on the top of control box, temperature sensor connects a plurality of external temperature measuring probe, and temperature measuring probe is covered with heat shield.
[0006] Further, the heat shield is inserted under the surface layer of the coal pile.
[0007] Further, the visible light camera and the infrared detector are connected to the display, the display, the air monitoring appearance and the temperature sensor are all connected to the controller, and the output end of the controller is connected to the alarm and the remote monitoring PC end.
[0008] The utility model has the advantages that the utility model replaces traditional manual inspection, utilizes visible light camera, infrared detector and temperature measuring probe to carry out real-time, all -round safety monitoring to coal mine stockyard, and the monitoring effect is better, and the danger caused by temperature exceeding the standard or dangerous gas leakage is avoided, and the safety is higher.

[0015] In order to make the purpose, technical scheme and beneficial effect of the utility model more clearly, the technical scheme in the utility model is further explained below in combination with examples.
[0016] As Figures 1 to 5 shown, a coal mine yard safety monitoring equipment, including base 1, the base 1 is equipped with stand 2, the top of stand 2 is equipped with monitoring platform 7, the monitoring platform 7 is equipped with pan-tilt, the pan-tilt usually adopts 360 rotatable pan-tilt, the pan-tilt is equipped with visible light camera 8 and infrared detector 9, the yard picture is monitored using visible light camera 8, the infrared imaging information of the yard picture is monitored using infrared detector 9, the upper side of stand 2 is equipped with fixing frame, the fixing frame provides support, the fixing frame is equipped with air monitor, the air monitor monitors the coal mine yard environment, whether there is dangerous gas in the air is monitored, the lower side of stand 2 is equipped with control box 3, the control box 3 is equipped with display 4, temperature sensor 5 and controller, the top of control box 3 is equipped with alarm 6, the alarm 6 usually adopts audible and visual alarm 6, the temperature sensor 5 is connected with several external temperature measuring probes 10, the temperature measuring probe 10 is equipped with heat shield 11, the heat shield 11 is usually inserted under the coal pile surface layer.
[0017] Visible light camera 8 and infrared detector 9 are connected with display 4, display 4, air monitor and temperature sensor 5 are all connected with controller, the output end of controller is connected with alarm 6 and remote monitoring PC end.
[0018] In use, the temperature measuring probe 10 with the heat conducting cover 11 is inserted below the surface layer of the coal pile, the temperature measuring probe 10 transmits the measured data to the temperature sensor 5, the temperature sensor 5 converts the data into temperature values and transmits the temperature values to the controller; the video pictures and infrared thermal imaging information of the yard monitored by the visible light camera 8 and the infrared detector 9 are transmitted to the display 4 for display, and the display 4 transmits the imaging information to the remote monitoring PC end through the controller, so that the staff can monitor the pictures of the yard in real time at the remote monitoring operation station; the current environment is monitored by the air monitor, and the air monitor sends the monitoring signal to the controller.
[0019] If dangerous gas leakage occurs in the environment or the temperature measured by the temperature sensor 5 exceeds the set value, either of the two signals is triggered, which will make the controller send an instruction to the alarm 6 to alarm on site, and at the same time, the alarm is transmitted to the remote monitoring PC end for warning.
