Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle devices, and particularly to an unmanned aerial vehicle device based on mine blasting. Background Art

[0002] During the mining process of a mine, the technical department must timely and accurately grasp the geological structure of the mine. At present, the means of studying the geological structure of the mine are plane and section line mapping, which is difficult and has a low visualization degree, and cannot present the structure situation in a visual way. With the development of unmanned aerial vehicle technology, unmanned aerial vehicle technology is currently widely used in agricultural and mining production, especially in terrain surveying, information monitoring, etc., which is more excellent than the old methods. The application of unmanned aerial vehicles in the field of mine exploitation is becoming more and more extensive and very mature.

[0003] When the existing unmanned aerial vehicles for mine operations transport some equipment or blasting materials, the unmanned aerial vehicle hoists the items for high-altitude transportation through the hoisting ropes at the bottom of the airframe. However, when the unmanned aerial vehicle is flying at high altitude, the hoisted items are prone to shaking through the ropes, and the transportation stability is limited, resulting in a stall danger during the flight of the unmanned aerial vehicle and causing it to fall and be damaged. For this reason, we propose an unmanned aerial vehicle device based on mine blasting. Summary of the Invention

[0004] The present invention mainly solves the technical problems existing in the above-mentioned prior art, and provides an unmanned aerial vehicle device based on mine blasting.

[0005] To achieve the above object, the present invention adopts the following technical solution. An unmanned aerial vehicle device based on mine blasting includes an unmanned aerial vehicle main body, wings, propeller blades, a boom assembly, and a bottom support. A storage box is arranged at the bottom of the unmanned aerial vehicle main body, a storage box is arranged inside the storage box, a hoisting mechanism is installed at the bottom of the unmanned aerial vehicle main body, a connecting seat is installed above the storage box, an installation groove is opened at the top of the connecting seat, an installation seat is installed at the bottom of the hoisting mechanism, limiting mechanisms are installed at both sides of the top of the connecting seat, a telescopic clamping member is telescopically arranged inside the limiting mechanism, a pulling groove is opened inside the telescopic clamping member, connecting members are installed on both sides of the telescopic clamping member, and the connecting members and the limiting mechanism are supported and connected by springs in cooperation.

[0006] Preferably, when the telescopic clamping member inside the limiting mechanism is pulled outwards through the pulling groove, the unmanned aerial vehicle main body can be in butt joint and clamping cooperation with the installation groove inside the connecting seat through the installation seat at the bottom of the hoisting mechanism. When the telescopic clamping member is released, the telescopic clamping member is in an elastic reset moving state inside the limiting mechanism by the pulled spring.

[0007] Preferably, when the telescopic clamping member moves above the installation seat, the telescopic clamping member is in a limiting clamping state with the installation seat inside the installation groove.

[0008] Preferably, an adjusting clamping member for limiting the storage box is arranged at one edge position of the storage box. A circular groove is formed inside the adjusting clamping member. A circular shaft is installed at the position of the storage box corresponding to the circular groove. A damping pad is arranged inside the circular groove. The adjusting clamping member is in damping rotation connection and cooperation with the outside of the circular shaft through the damping pad inside the circular groove. A dial is installed on one side of the adjusting clamping member.

[0009] Preferably, when the adjusting clamping member is rotated to the position on one side of the storage box through the dial, the adjusting clamping member is in a state of limiting and fixing the storage box inside the storage box.

[0010] Preferably, a spherical groove is formed on the periphery of the bottom support. A movable clamping ball is movably clamped inside the spherical groove. The movable clamping ball is of a spherical structure. The bottom of the support arm assembly is fixedly connected and cooperated with the movable clamping ball through a connecting shaft. An elastic sleeve is sleeved outside the connecting shaft. The top of the elastic sleeve is fixedly connected to the lower end of the support arm assembly and the bottom of the elastic sleeve is fixedly connected to the surface of the bottom support. The elastic sleeve has elastic characteristics itself.

[0011] Preferably, when the support arm assembly at the bottom of the UAV body lands and is supported by the bottom support, the spherical groove inside the bottom support is in a state of being movably inclined and adjustable outside the movable clamping ball, and the bottom support is in a support buffer state through the elastic sleeve.

[0012] Preferably, the support arm assembly is composed of an upper support arm and a lower support arm. An internal cavity is formed inside the upper support arm. A through groove penetrating the internal cavity is formed at the bottom of the upper support arm. The upper end of the lower support arm is provided with a support shaft penetrating the through groove. One end of the support shaft is in limit cooperation with the inside of the internal cavity through a limiting member. An internal airbag supported and connected to the limiting member is arranged inside the internal cavity.

[0013] Preferably, when the support arm assembly at the bottom of the UAV body lands and is supported by the bottom support, the lower support arm is in a support buffer state for the internal airbag inside the internal cavity through the limiting member at one end of the support shaft.

[0014] The present invention provides a UAV device based on mine blasting. It has the following beneficial effects:

[0015] 1. This is a UAV device based on mine blasting. In this article, when the UAV body is used for cargo transportation, the two sets of telescopic clips are first controlled by the pull groove to be pulled outward inside the limit mechanism. At this time, the lifting mechanism at the bottom of the UAV body can be inserted into the mounting groove inside the connecting seat through the mounting seat for docking. At the same time, the two sets of springs will be elastically stretched. When the telescopic clips are released, the telescopic clips will be elastically reset through the springs on the two sets of connecting parts to limit the mounting seat inside the mounting groove. At this time, the storage box will be docked and fixed, and the material can be directly placed in the storage box for storage. In this way, the UAV body can avoid shaking of the material when driving the storage box for high-altitude transportation, which will cause the overall instability of the UAV body and cause stall and fall, thereby achieving fixed lifting transportation through the storage box, improving the transportation stability of the UAV body, and avoiding stall damage to the UAV body during flight.

[0016] 2. This is a device based on a mining blasting drone. After the storage box is docked and fixed with the mounting seat at the bottom of the lifting mechanism through the connecting seat, the conveyed material can be placed in the storage box for storage, and the storage box can be pushed into the storage box for storage. At this time, the adjustment card can be rotated and adjusted by turning the dial to make the adjustment card rotate to the surface of the storage box to limit and fix the storage box. The same is true when the storage box is opened, thereby achieving the effect of facilitating the placement and removal of materials inside the storage box.

[0017] 3. A mine blasting UAV device, wherein the lower end of the arm assembly is movably assembled with the bottom support, and the lower end of the arm assembly is movably engaged with the inside of the spherical groove through an active snap-in ball at the end of the connecting shaft, and the outer sleeve of the connecting shaft is provided with an elastic sleeve which is mutually connected and supported with the arm assembly and the bottom support. The elastic sleeve itself is elastic. When the main body of the UAV is supported by the bottom support for landing, if it encounters an uneven ground in the mine, the bottom support can be adjusted to the front and rear tilt support according to the inclination of the terrain, and support and buffer are performed through the elastic sleeve, thereby achieving the effect of ensuring the landing stability of the main body of the UAV.

[0018] 4. A mine blasting drone device, wherein the arm assembly is connected and matched by an upper arm and a lower arm, the upper end of the lower arm is telescopically connected to the inside of the through slot through a support shaft, the upper end of the support shaft is engaged with the limit in the built-in cavity through a limit piece and is supported and squeezed with the built-in airbag. When the drone body lands on the ground through the bottom support at the bottom of the arm assembly, the upper arm can be located outside the support shaft and telescopically slide downward under the gravity inertia of the drone body, and the limit piece at the upper end of the support shaft can squeeze the built-in airbag inside the built-in cavity, and the internal air pressure of the built-in airbag can reduce the contact resonance effect of the drone body itself when it lands, thereby reducing the landing pressure of the drone body and avoiding the effect of resonance damage to the drone body's own components.

The bottom of the boom assembly 4 is fixedly connected with the movable clamping ball 23 through a connecting shaft 24. An elastic sleeve 25 is sleeved outside the connecting shaft 24. The top of the elastic sleeve 25 is fixedly connected with the lower end of the boom assembly 4 and the bottom of the elastic sleeve 25 is fixedly connected with the surface of the bottom support 5. The elastic sleeve 25 has elastic characteristics. The boom assembly 4 is composed of an upper boom 26 and a lower boom 27. An internal cavity 28 is opened inside the upper boom 26.

[0037] The working principle of the present invention:

[0038] When the drone body 1 is used for freight transportation, first, the two telescopic latches 12 inside the limiting mechanism 11 are controlled to move outward through the slot 13. At this time, the hoisting mechanism 7 at the bottom of the drone body 1 can be inserted into the mounting groove 10 inside the connecting seat 9 through the mounting seat 8 for butt-joint. At the same time, the two springs 15 will be elastically stretched. When the telescopic latches 12 are released, the telescopic latches 12 will move elastically in place through the springs 15 on the two connecting pieces 14, so as to limit and clamp the mounting seat 8 inside the mounting groove 10. At this time, the storage tank 6 will complete the butt-joint fixation, and the materials can be directly put into the storage box 16 for storage. In this way, when the drone body 1 drives the storage tank 6 for high-altitude transportation, the materials can be prevented from shaking, resulting in the instability of the whole drone body 1 and stalling and falling. Therefore, through the fixed hoisting and transportation of the storage tank 6, the transportation stability of the drone body 1 is improved, and the drone body 1 is prevented from stalling and being damaged during flight.
