Description

Technical Field

[0001] The utility model relates to the technical field of coal mine inspection equipment, in particular to automatic inspection equipment for coal mine safety inspection. Background Art

[0002] Coal is the world's most abundant and widely distributed conventional energy source, a crucial strategic resource, and is widely used in industrial production, including steel, electricity, and chemicals, as well as in residential areas. To ensure safe production, coal mining requires real-time monitoring of gas, oxygen, and other conditions within the mine using patrol devices. Currently, existing track-mounted intelligent patrol robots in coal mines often utilize multiple integrated gas sensors for gas detection.

[0003] Since the air in mines easily contains a lot of impurities, when the gas sensor uses the probe to detect gas, a filter cover is installed on the outside to filter out solid impurities in the gas.

[0004] However, as the usage time increases, impurities are likely to accumulate and embed on the filter cover, affecting the flow rate of gas into the gas probe, and thus causing certain interference with the accuracy of gas composition detection.

[0005] For this reason, we propose to design an automatic inspection equipment for coal mine safety inspection. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] See also Figure 1-3 The utility model provides an automatic inspection device for coal mine security inspection, including an equipment box 1, a driving frame 2 is fixedly connected to the top of the equipment box 1, a driving wheel 3 is provided on the top of the driving frame 2, guide wheels 4 are provided on both sides of the driving frame 2, a monitoring probe 5 is provided at the bottom of the equipment box 1, a gas probe 6 is provided on the side of the equipment box 1 close to the screen of the monitoring probe 5, a cleaning box 7 is fixedly connected to the outside of the gas probe 6, and a filter cover 8 is fixedly connected to the outside of the cleaning box 7.

[0025] The gas probe 6 passes through the cleaning box 7 and is connected to its interior. An air hole 13 corresponding to the gas probe 6 is provided inside the cleaning box 7. The center of the air hole 13 corresponds to the center of the filter cover 8. Under normal conditions, the gas filtered by the filter cover 8 can enter the gas probe 6 through the air hole 13.

[0026] A slide 9 is provided at one end inside the cleaning box 7, and a pump body 10 is fixedly connected to one side of the outer wall of the equipment box 1. The slide 9 is located in the cleaning box 7 at one end close to the pump body 10, and the slide 9 is slidably connected to the bottom of the cleaning box 7 to facilitate the movement of the slide 9 in the cleaning box 7.

[0027] The exhaust end of the pump body 10 is fixedly connected to a transfer tube 11 corresponding to the cleaning box 7. The transfer tube 11 passes through the cleaning box 7 and is fixedly connected to an air nozzle 12. The center of the air nozzle 12 is against the center of the inner wall of the slide 9, which facilitates the pump body 10 to supply high-pressure gas into the cleaning box 7 and push the slide 9 to close the gas probe 6 to prevent damage to the gas sensor connected thereto.

[0028] A spring 14 is fixedly connected between the inner wall of the slide 9 and the inner wall of the cleaning box 7. An opening is provided on the side of the slide 9 close to the spring 14. A guide plate 15 is fixedly connected to the side of the slide 9 away from the opening to facilitate guiding the airflow and making it easier to spray toward the filter cover 8.

[0029] When in use, the pump body 10 is connected to an external power source and started, and a filter element is installed at the air suction end of the pump body 10 to keep the ejected gas clean.

[0030] The pump body 10 is periodically started through external PLC programming. When the pump body 10 is started, high-pressure airflow is supplied to the cleaning box 7 through the transfer tube 11 and sprayed to the slide 9 through the air nozzle 12. Under the action of the high-pressure airflow, the slide 9 is driven to move in the cleaning box 7 and the spring 14 is stretched.

[0031] At the moment of jetting, the slide 9 moves and blocks the air hole 13, which can prevent the high-pressure airflow from damaging the gas sensor corresponding to the gas probe 6. Under the action of the guide plate 15, the airflow is more easily ejected toward the filter cover 8, and the impurities accumulated and embedded on the filter cover 8 are backwashed, so that the impurities fall off to the outside, thereby ensuring the passability of the filter cover 8.

[0032] When the pump body 10 is finally closed, the slide 9 is driven to return to its original position under the elastic force of the spring 14, and the gas probe 6 can be put into operation again.

[0033] Note: During the flushing process, the gas sensor corresponding to the gas probe 6 can be turned off to protect the gas sensor and prevent damage.

[0034] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
