Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, specifically a coal mine environmental monitoring device. Background Technology

[0002] A coal mine is an area where humans extract coal resources in coal-rich areas, generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, underground tunnels are typically dug to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil is typically stripped away to extract the coal; this is called an open-pit coal mine. The vast majority of coal mines in my country are underground mines. A coal mine encompasses a large area, including both above-ground and underground areas, as well as related facilities. A coal mine is a rationally excavated space created by humans when mining coal-rich geological strata, typically including tunnels, shafts, and working faces. Coal is the most important solid fuel and is a type of combustible organic rock. It is formed from abundant vegetation that grew over a certain geological era, gradually accumulating into thick layers in suitable geological environments, buried underwater or in silt, and undergoing natural coalification over long geological periods.

[0003] In existing technologies, coal mines typically contain harmful gases such as methane and CO. To ensure the safety of coal mining, gas detectors are needed to monitor the gases in the mine. However, in existing coal mine environmental monitoring devices, the display screen is easily obscured by dust, making it difficult for workers to easily observe the data. The screen needs to be wiped clean to view the data, which is inconvenient. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be noted that the terms "vertical", "up", "down", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Please see Figure 1-2 This utility model provides a technical solution: a coal mine environmental monitoring device, including a base 1, a controller 4, a monitoring device body 6, and a cleaning mechanism 7. The controller 4 is fixedly connected to the top rear end of the base 1, and a support rod 5 is fixedly connected to the top center of the base 1. The top of the support rod 5 is fixedly connected to the bottom center of the top seat 9. A sliding sleeve 11 is slidably connected to the surface of the support rod 5, and the monitoring device body 6 is fixedly connected to the front of the sliding sleeve 11.

[0028] Furthermore, threaded holes are provided on both sides of the base 1, and screws 2 are installed through the threaded holes. A knob 3 is fixedly connected to the top of the screws 2.

[0029] Furthermore, an extension block 12 is fixedly connected to the rear end of the sliding sleeve 11. The top of the extension block 12 is connected to the bottom telescopic end of the telescopic cylinder 10, and the top fixed end of the telescopic cylinder 10 is fixedly connected to the bottom of the top seat 9.

[0030] Furthermore, the bottom front ends of the top seat 9 are connected to the top fixed end of the telescopic rod 8, and the bottom telescopic end of the telescopic rod 8 is fixedly connected to the top of the monitoring device body 6.

[0031] Before use, take this utility model to the coal mine and place it in a suitable position. Then, the staff should rotate the knob 3 appropriately. The rotation of the knob 3 will cause the screw 2 to move downward along the threaded hole, thereby inserting the screw 2 into the soil of the coal mine and fixing the utility model.

[0032] Then, the height of the main body 6 of the monitoring device is controlled by the controller 4. Specifically, the telescopic cylinder 10 is activated by the controller 4. The activation of the telescopic cylinder 10 will cause it to extend or retract, thereby changing the height of the extension block 12, which in turn changes the height of the sliding sleeve 11, and thus changes the height of the main body 6 of the monitoring device.

[0033] Considering that the gases that need to be detected in coal mines are mainly methane and CO, which are relatively simple, the height of the main body 6 of the monitoring device can be determined before use. The height also makes it convenient for staff to view the display screen 602. Once the height is determined, it can be used.

[0034] It should be noted that during coal mining, if workers feel that the environment is abnormal but the main body 6 of the monitoring device does not alarm, the height of the main body 6 of the monitoring device can be adjusted to multiple positions through the controller 4 to monitor the air quality at multiple locations and improve the monitoring accuracy.

[0035] Please see Figure 3 An alarm light 601 is provided at the top center of the main body 6 of the monitoring device. A display screen 602 is provided at the top front of the main body 6 of the monitoring device. A main button 603 is provided at the center front of the main body 6 of the monitoring device. A buzzer 604 is provided at the bottom front of the main body 6 of the monitoring device. A blocking ring 605 is provided on the outer surface of the buzzer 604. The blocking ring 605 is fixedly connected to the front of the main body 6 of the monitoring device and will block dust.

[0036] A dust cover 13 is fixedly connected to the outer surface of the display screen 602. The dust cover 13 is made of transparent material and is coated with a high-grade silicone acrylic coating. This coating is a dustproof coating that can protect the dust cover 13 from dust to a certain extent. A cleaning mechanism 7 is fixedly connected to the outer surface of the dust cover 13.

[0037] Specifically, it should be noted that the main body 6 of the monitoring device is based on existing mature technology, and the internal electrical connections and specific circuit structure of the main body 6 of the monitoring device will not be described in detail here.

[0038] In addition, for monitoring purposes, several monitoring devices are installed on the outer surface of the main body 6 of the monitoring device. This is a mature existing technology, and its internal structure and working principle will not be described in detail here.

[0039] It should be noted that during use, when the main body 6 of the monitoring device detects an abnormality, the warning light 601 will flash and the buzzer 604 will give an alarm. The specific connection methods of the main body 6 of the monitoring device, the warning light 601, and the buzzer 604 are existing mature technologies, and the electrical connection relationships and specific circuit structures thereof will not be elaborated in detail herein.

[0040] Please refer to Figure 4 、 Figure 5 , Figure 4 and Figure 5 The cleaning mechanism 7 of the present utility model, wherein the cleaning mechanism 7 is in the shape of a "mouth". On both front ends of the inner surface of the cleaning mechanism 7, sliding grooves 701 are provided. The centers of the top and bottom of the sliding grooves 701 are respectively connected to both ends of a screw rod 702. A slider 703 is sleeved on the surface of the screw rod 702. The slider 703 is fitted and slidably connected to the sliding groove 701. A connecting block 704 is provided between the two sliders 703. A brush is provided on the back surface of the connecting block 704. The brush is in contact with the front surface of the dust-proof cover 13.

[0041] Furthermore, a driving cavity 705 is provided inside the top of the cleaning mechanism 7. The center of the top of the screw rod 702 is fixedly connected to a rotating shaft 709. The top of the rotating shaft 709 is located inside the driving cavity 705. A synchronous pulley 708 is fixedly sleeved on the surface of the rotating shaft 709. The bottom of the synchronous pulley 708 is in contact with the bottom of the driving cavity 705. The two synchronous pulleys 708 are connected by a synchronous belt 707.

[0042] Furthermore, a driving motor 706 is fixedly connected to one side of the top of the driving cavity 705. The bottom output end of the driving motor 706 is connected to one of the rotating shafts 709.

[0043] It should be noted that the inner surface of the cleaning mechanism 7 is in contact with the outer surface of the dust-proof cover 13 and is appropriately sealed by rubber strips to prevent dust from entering the outer surface of the dust-proof cover 13 through the gap between the cleaning mechanism 7 and the dust-proof cover 13, resulting in a more complex cleaning of the outer surface of the dust-proof cover 13.

[0044] During use, the controller 4 will start the driving motor 706 at regular intervals. The staff can set the time threshold through the controller 4. This is an existing mature technology, and the specific working principle thereof will not be elaborated in detail herein.

[0045] When the drive motor 706 starts, it will cause the rotating shaft 709 to rotate. The rotation of the rotating shaft 709 will cause the lead screw 702 to rotate, and the rotation of the rotating shaft 709 will also cause the synchronous pulley 708 to rotate. The rotation of the synchronous pulley 708 will cause another synchronous pulley 708 to rotate through the synchronous belt 707, thereby causing another rotating shaft 709 to rotate. Finally, the drive motor 706 will start to rotate both lead screws 702. The rotation of the two lead screws 702 will cause the slider 703 to move along the slide groove 701, thereby causing the connecting block 704 to move. The movement of the connecting block 704 will cause the brush to move along the dust cover 13, sweeping away the dust on the surface of the dust cover 13, making it convenient for the staff to view the data displayed on the display screen 602.

[0046] It should be noted that the drive motor 706 is a reciprocating motor, which will cause the connecting block 704 to reciprocate. Specifically, the initial position of the connecting block 704 is at the top inside the clearing mechanism 7. Under the drive of the drive motor 706, it moves downward. Because it is a reciprocating motor, after the connecting block 704 is moved to the bottom, it will move upward, so that the connecting block 704 returns to the far end.

[0047] It should also be noted that the bottom of the cleaning mechanism 7 has several dust inlets, from which dust will fall and clean itself.

[0048] It is worth noting that the telescopic cylinder 10 and the drive motor 706 are controlled by the controller 4. Since the controller is a common device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0049] Meanwhile, the telescopic cylinder 10 is also a mature existing technology. The gas structure of the telescopic cylinder 10 is located on the top of the top seat 9. The connection relationship and working principle between other structures of the telescopic cylinder 10 will not be described in detail here.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
