Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mine safety monitoring technology, and in particular relates to a monitoring device mounted on a mine fire safety patrol drone. Background Technology
[0002] During the mining process, in order to monitor the mine, especially during the high-temperature season when fires are more likely to occur, it is necessary to strengthen the safety monitoring of the mine to avoid the impact of fires on normal mining operations or even serious damage to mining equipment.
[0003] Because mines are often quite large, current monitoring methods, in addition to installing cameras on the ground in the mining area, also include using drones for patrol and monitoring.
[0004] Specifically, drone surveillance not only covers a wide area, but also requires only automated backend operation, resulting in higher monitoring efficiency. While existing drones are equipped with cameras, their fixed installation makes it difficult to detect fires promptly when the drone enters densely wooded areas due to tree cover.
[0005] Meanwhile, when the drone locates the fire, it cannot land in the fire area and flies at low altitude to collect images. As a result, the system can observe the location of the fire, but cannot clearly observe the extent of the fire, and cannot accurately assess the fire.
[0006] Therefore, in practical work, fire safety monitoring in mines requires not only high-altitude aerial surveillance, but also immediate landing to capture monitoring footage once a fire is detected, facilitating accurate assessment of the fire situation by the backend. However, current drones are generally unable to complete these tasks during safety patrols. Utility Model Content
[0007] Based on the above background, the purpose of this utility model is to provide a monitoring device mounted on a mine fire safety patrol drone.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A monitoring device mounted on a mine fire safety patrol drone includes a monitoring and walking mechanism mounted on the drone.
[0010] The mounted monitoring walking mechanism includes a chassis mounted on the drone, with mounted monitoring mechanisms installed on both sides of the chassis; the mounted monitoring mechanism includes a bracket fixedly connected to the chassis, an adjusting arm structure hinged to the bracket, a monitoring adjusting shaft rotatably connected to the adjusting arm structure, and a camera structure mounted on the monitoring adjusting shaft through the adjusting structure.
[0011] The camera structure includes a camera and an electric push rod for adjusting the camera.
[0012] The monitoring device mounted on the mine fire safety patrol drone also includes a walking structure installed on a support frame. After landing, the drone walks on the ground and collects monitoring images through the walking structure.
[0013] Preferably, the chassis includes a chassis frame and a cover installed on the top of the chassis frame;
[0014] The top of the box cover is fixedly connected to several track holders that are pulled to the bottom of the drone.
[0015] Preferably, the bracket includes L-shaped bracket portions arranged symmetrically at the front and rear, and the L-shaped bracket portions are fastened to the chassis frame by bolts;
[0016] The adjusting arm structure includes adjusting arms respectively hinged to the L-shaped bracket portion;
[0017] The monitoring and adjustment shaft is rotatably connected between the adjustment arms.
[0018] Preferably, a first motor for driving the monitoring and adjusting shaft to rotate is fixedly installed on one side of the adjusting arm;
[0019] A second motor that drives the adjustment arm to rotate is fixedly installed on one side of the L-shaped bracket.
[0020] Preferably, the adjustment structure includes a height adjustment screw threadedly connected to the monitoring and adjustment shaft;
[0021] The bottom of the height adjustment screw is fixedly connected to a mounting base, and the electric push rod is fixedly installed at the top of the mounting base.
[0022] Preferably, the walking structure includes walking wheels that are hinged to and mounted on the L-shaped support portion;
[0023] The walking structure also includes electrically telescopic rods that are hinged to the chassis frame;
[0024] The push end of the electric telescopic pole is hinged to the walking wheel.
[0025] Preferably, the walking wheel includes a wheel arm hinged to an L-shaped bracket, and the pushing end of the electric telescopic rod is fixedly connected to a hinge seat, which is hinged to the wheel arm via a pin.
[0026] A roller structure is installed at the lower end of the wheel arm.
[0027] Preferably, the roller structure includes an active roller mounted on one side of the wheel arm, and a hub motor is installed inside the hub of the active roller, with the output shaft of the hub motor fixedly connected to the wheel arm.
[0028] Preferably, the roller structure further includes a driven roller rotatably connected to the other side of the wheel arm.
[0029] This utility model has the following beneficial effects:
[0030] 1. During operation, the second motor initially adjusts the monitoring angle of the camera structure, while the first motor performs further adjustments. The purpose of this method is to allow the drone to continuously adjust the camera angle as it descends to the fire location, facilitating better monitoring of the fire area. In particular, adjusting the camera angle helps avoid obstructions such as trees, enabling the drone to approach the fire and capture clear aerial footage.
[0031] 2. Before landing, the drone's wheels are pushed forward using an electric telescopic boom (normally, the wheels are nearly horizontal to reduce flight resistance). After the boom is pushed, the rollers on both sides separate, allowing the drone to descend and land. The drone then comes to a stop, enabling it to move on the ground. When encountering obstacles, the drone can take off again to overcome them. This method allows for close proximity to the fire's location, facilitating close-range fire monitoring.

[0041] Example 1
[0042] like Figure 1-4 As shown, a monitoring device mounted on a mine fire safety patrol drone includes a monitoring and walking mechanism mounted on the drone.
[0043] By mounting a monitoring walking mechanism, it can be used in conjunction with high-altitude drone monitoring, and also allows for close-range monitoring of the fire from ground-based walking mechanisms when a fire is detected.
[0044] Specifically, the monitoring and walking mechanism includes a chassis 1 mounted on the drone. The chassis 1 includes a chassis 1 frame and a cover 11 installed on the top of the chassis 1 frame. In the existing method, the power supply and controller for the operation of the drone and the following working components such as motors and cameras are installed inside the chassis 1.
[0045] Similar to existing drone mounting methods, the top of the aforementioned box cover 11 is fixedly connected to several L-shaped track holders 12 that are pulled to the bottom of the drone. In the existing method, the track holders 12 are snapped into the track seats at the bottom of the drone, and the track seats are fastened to the track holders with bolts, just as in the existing method.
[0046] The aforementioned chassis 1 has a monitoring mechanism mounted on each of its two sides; the monitoring mechanism includes a bracket fixedly connected to the chassis 1. Specifically, the bracket includes L-shaped bracket parts 21 arranged symmetrically at the front and back, and the L-shaped bracket parts 21 are fastened to the frame of the chassis 1 by bolts.
[0047] Meanwhile, an adjustment arm structure is hinged to the bracket, and a monitoring adjustment shaft 25 is rotatably connected to the adjustment arm structure (specifically, the monitoring adjustment shaft 25 is rotatably connected between the adjustment arms as described below, in the same way as the existing shaft rotation connection). A camera structure is installed on the monitoring adjustment shaft 25 through the adjustment structure.
[0048] Specifically, the adjusting arm structure includes adjusting arms 22 (adjusting arms 22 are hinged to L-shaped bracket portions 21 via pins) that are respectively hinged to L-shaped bracket portions 21. At the same time, a second motor 23 for driving the adjusting arms 22 to rotate is fixedly mounted on the rear L-shaped bracket portion 21. Specifically, the output shaft of the second motor 23 is fixedly connected to the adjusting arms 22 and rotatably connected to the L-shaped bracket portion 21.
[0049] This method enables the second motor 23 to be turned on during the monitoring process to adjust the angle of the camera structure.
[0050] The camera structure includes a camera 26 and an electrically operated push rod 27 for adjusting the camera 26. The electrically operated push rod 27 is a conventional electrically operated telescopic rod disclosed in the prior art.
[0051] The monitoring device mounted on the mine fire safety patrol drone also includes a walking structure installed on a support frame. After landing, the drone walks on the ground and collects monitoring images through the walking structure.
[0052] Meanwhile, a first motor 24 that drives the monitoring and adjustment shaft 25 to rotate is fixedly installed on the upper end of the rear side adjustment arm 22. Similar to existing methods, the output shaft of the first motor 24 is fixedly mounted on the monitoring and adjustment shaft 25.
[0053] During operation, the second motor 23 is used to initially adjust the monitoring angle of the camera 26 structure, and the first motor is used for further adjustment. The purpose of this method is to allow the drone to continuously adjust the angle of the camera 26 structure as it descends to the fire location, thus facilitating the camera's monitoring of the fire area. In particular, adjusting the angle of the camera 26 structure helps avoid obstructions such as trees, allowing the drone to approach the fire location and capture clear monitoring footage from the air.
[0054] The aforementioned adjustment structure includes a height adjustment screw 28 threadedly connected to the monitoring and adjustment shaft 25; the bottom of the height adjustment screw 28 is fixedly connected to a mounting base 271, and the electric push rod 27 is fixedly installed at the top position of the mounting base 271.
[0055] During operation, when the drone approaches the fire location, the electric push rod 27 pushes the camera 26 downwards to further increase the distance between the monitoring camera 26 and the target location, making it easier to clearly monitor the scene.
[0056] The purpose of the height adjustment screw is to adjust the height of the monitoring camera 26 according to the actual situation. For example, before the drone takes off, the distance between the camera 26 and the ground can be adjusted by adjusting the height adjustment screw 28 (the height adjustment screw 28 is threaded to the monitoring adjustment shaft 25. The height can be adjusted by rotating the height adjustment screw 28. At the same time, the angle of the camera 26 can also be adjusted). This makes it easier for the camera 26 to get closer to the ground position (fire point) after the electric push rod 27 is pushed.
[0057] In practical applications, the above structure enables the drone to perform safe monitoring above the forest. When a fire occurs, the drone lowers its altitude and uses the above adjustment method to lower the camera 26 to avoid interference from tree branches and leaves, thus enabling convenient and accurate acquisition of the fire point. This provides accurate and clear images to facilitate the back-end personnel's judgment of the fire situation.
[0058] Example 2
[0059] like Figure 1-4 As shown, based on the structure of Embodiment 1, this embodiment includes a walking structure that is hinged to L-shaped bracket 21 for convenient close-range monitoring of the scene after the drone lands. Specifically, the walking structure also includes an electric telescopic rod 34 (with a lug 341 fixedly connected to the electric telescopic rod 34, and the lug 341 hinged to the chassis 1 frame via a pin) that is hinged to the chassis 1 frame.
[0060] The push end of the aforementioned electric telescopic pole 34 is hinged to the walking wheel.
[0061] Specifically, the traveling wheel includes a wheel arm 351 hinged to the L-shaped bracket portion 21 (the wheel arm 351 is similarly hinged via a pin). The pushing end of the electric telescopic rod 34 is fixedly connected to a hinge seat, which is hinged to the wheel arm 351 via a pin. A roller structure is installed at the lower end of the wheel arm 351.
[0062] The roller structure includes a drive roller 31 mounted on one side of the wheel arm 351. A hub motor 32 is installed inside the hub of the drive roller 31 (during operation, the hub motor 32's motor body is fixed to the drive roller, and its output shaft is fixed to the wheel arm 351, thus driving the drive roller 31 to rotate). The output shaft of the hub motor 32 is fixedly connected to the wheel arm 351. The roller structure also includes a driven roller 33 rotatably connected to the other side of the wheel arm 351.
[0063] The aforementioned structure allows the drone to land by using an electric telescopic boom 34 to push its wheels (normally, the wheels are kept nearly horizontal to reduce flight drag). After the boom pushes, the rollers on both sides separate, allowing the drone to descend and land. The drone then comes to a stop and can move on the ground. When encountering obstacles, the drone can take off to overcome them. This method enables the drone to approach the location of a fire at close range, facilitating close-range fire monitoring.
[0064] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
