Description

Technical Field

[0001] The present invention relates to the technical field of bare soil covering equipment, and more specifically, to a bare soil covering device. Background Art

[0002] Currently, the most common method for covering bare soil at construction sites is still the manual net-pulling covering method. During operation, it is often necessary to manually pull a close-mesh net to cover the bare soil, idle sand, construction waste, etc. within the site. Once faced with a large construction operation area, such as during the basic operation stage or the general leveling construction stage, there are often large areas that need to be covered. At this time, more labor is required on-site, and it takes a long time to complete the covering operation. Especially during the basic construction stage, there are many potholes in the site. When workers are covering the soil, it is not only inconvenient to operate but also poses certain safety hazards. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a bare soil covering device that can effectively solve the problems of inconvenient operation and potential safety risks during the current manual pulling of a close-mesh net for covering.

[0006] When covering bare soil and / or construction waste, through the connection of the hanging rope with the close-mesh net, then control the drone to take off, so that the close-mesh net unfolds and flies above the bare soil, and then control the drone to descend. When it descends to a certain position, the release device drops the hanging rope, so that the close-mesh net is separated from the drone and then falls onto the bare soil to cover the bare soil and / or construction waste below it.

[0007] In some possible implementation manners, in order to effectively realize the connection between the close-mesh net and the drone;

[0009] In some possible implementation manners, in order to effectively remove the close-mesh net automatically;

[0010] The bolt driving device includes a driving motor installed at the bottom of the base, and a rocker arm perpendicular to the output shaft of the driving motor and connected to one end thereof; the rocker arm is slidably hinged to the end of the bolt away from the vertical plate.

[0011] In some possible implementation manners, a waist-shaped hole is provided on the rocker arm along its axis, and the end of the bolt away from the vertical plate is hinged to the waist-shaped hole.

[0012] In some possible implementation manners, two vertical plates are respectively provided with pin holes in the horizontal direction, and the two groups of pin holes are coaxial.

[0013] In some possible implementation manners, in order to effectively limit the rotation amplitude of the rocker arm and avoid the situation of the bolt being stuck due to the over-large rotation amplitude of the rocker arm;

[0014] The bolt driving device further includes limiting blocks arranged on both sides of the rocker arm on the side of the driving motor close to the rocker arm.

[0018] In some possible implementation manners, the unmanned aerial vehicle is a multi-rotor unmanned aerial vehicle.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] Compared with the prior art, the present invention uses a close-mesh net to cover the bare soil in a form of mechanical automation, reducing the time for manually covering the bare soil and the construction cost.

In the implementation of this application, "and / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In the description of the embodiments of this application, unless otherwise stated, the meaning of "a plurality" refers to two or more. For example, a plurality of positioning columns means two or more positioning columns. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The present invention will be described in detail below.

[0028] A bare soil covering device uses a dense mesh to cover the bare soil; it includes a drone 1 and a connecting device 2 installed at the bottom of the drone 1 and used to connect the dense mesh 10; the connecting device 2 includes a release device installed at the bottom of the drone 1 and a hanging rope connected to the release device and used to connect the sealing mesh.

[0029] When covering bare soil and / or construction waste, through the connection of the hanging rope with the dense mesh 10, then control the drone 1 to take off by a remote control adapted to the drone 1, so that the dense mesh 10 unfolds and flies above the bare soil, and then control the drone 1 to descend. When descending to a certain position, the release device drops the hanging rope, so that the dense mesh 10 is separated from the drone 1, and then falls onto the bare soil to cover the bare soil and / or construction waste below it.

[0030] In some possible implementation manners, in order to effectively realize the connection between the dense mesh 10 and the drone 1;

[0031] The connecting device 2 includes a base 21 installed at the bottom of the drone 1, vertical plates 22 symmetrically installed on one side of the base 21 away from the drone 1 along the vertical direction, a pin 23 passing through the vertical plates 22 and inserted into the other vertical plate 22, and a pin driving device for driving the movement of the pin 23; the hanging rope is hooked to the pin 23 and is located between the two vertical plates 22.

[0032] The base 21 is connected to the bottom of the frame 11 of the drone 1. Two vertical plates 22 are installed on the base 21, and there is a gap between the two vertical plates 22. When in use, the pin 23 will pass through one vertical plate 22 from the side away from the other vertical plate 22, pass through the vertical plate 22, the gap in sequence, and enter the other side plate. The part of the pin 23 located in the gap will be used to connect the hanging rope and ensure that the hanging rope can only move along the axis of the pin 23 in the gap, thereby reducing the sway of the safety net 10 connected to the hanging rope during the flight and transportation of the drone 1.

[0033] When in use, in a manual mode, before the drone 1 takes off, after connecting the pin 23, the hanging rope, and the safety net 10, the drone 1 is controlled by a remote controller to transport the safety net 10 to a designated position, and then the safety net 10 is manually removed again to complete the coverage of the bare soil at this position. However, this still requires a large amount of manual labor to remove the safety net 10.

[0034] Therefore, in some possible implementation manners, in order to reduce the use of manual labor and reduce the safety hazards of personnel working at the slope position; an automated method is adopted to remove the safety net 10 to reduce the safety hazards existing in manual work.

[0035] The pin driving device includes a driving motor 25 installed at the bottom of the base 21 and a rocker arm 24 perpendicular to the output shaft of the driving motor 25 and connected to one end thereof; the rocker arm 24 is slidably hinged to the end of the pin 23 away from the vertical plate 22.

[0036] When the drone 1 transports the safety net 10 to a designated position, it is necessary to remove the safety net 10. The controller, which is signal-connected to the driving motor 25, controls the rotation of the output shaft of the driving motor 25, causing the rocker arm 24 perpendicular to the output shaft to rotate, thereby driving the pin 23 to slide out of the vertical plate 22; thus, the hanging rope connected to the pin 23 slides off the pin 23; the hanging rope is no longer hooked to the pin 23. Under the action of gravity, the hanging rope and the safety net 10 move downward to cover the bare soil.

[0037] The pin driving device can adopt a linear electric push rod, a cylinder or a hydraulic cylinder, and its output end is connected to the pin 23.

[0038] In some possible embodiments, in order to effectively enable the pin 23 to move on the vertical plate 22 when the rocker arm 24 rotates;

[0039] The rocker arm 24 is provided with a waist-shaped hole along its axis, and one end of the pin 23 far from the vertical plate 22 is hinged to the waist-shaped hole.

[0040] In some possible embodiments, in order to ensure that the pin 23 can pass through one of the vertical plates 22 and enter the other vertical plate 22, thereby effectively realizing the support for the hanging rope hung on the pin 23;

[0041] The two vertical plates 22 are respectively provided with pin holes in the horizontal direction, and the two groups of pin holes are coaxial.

[0042] In some possible embodiments, in order to effectively realize the effective connection between the hanging rope and the vertical plate 22 and the dense mesh 10;

[0043] The hanging rope includes a ring hooked to the pin 23, a connecting rope connected to the ring, and a hook connected to the other end of the connecting rope.

[0044] In some possible embodiments, in order to effectively limit the rotation amplitude of the rocker arm 24 and avoid the situation that the pin 23 is stuck due to the over-large rotation amplitude of the rocker arm 24;

[0045] The pin driving device further includes limiting blocks arranged on both sides of the rocker arm 24 and on the side of the driving motor 25 close to the rocker arm 24.

[0046] The two limiting blocks are located on both sides of the rocker arm 24, and the included angle formed by their axes is less than 90°. When the rocker arm 24 abuts against the limiting block on the side close to the vertical plate 22, the pin 23 will pass through the vertical plate 22 close to this limiting block and extend into the other vertical plate 22, forming a stable support for the hanging rope to be hooked.

[0047] When the rocker arm 24 abuts against the limiting block far from the vertical plate 22, at this time, the end of the pin 23 far from the rocker arm 24 will be located in the gap. The ring can be put on the pin 23, and then the pin 23 is moved towards the other pin hole by the pin driving device to complete the connection of the hanging rope.

[0048] In some possible embodiments, the drone 1 includes a frame 11 and two sets of landing gears 12 installed at the bottom of the frame 11, and the connecting device 2 is installed at the bottom of the frame 11 and between the two sets of landing gears 12.

[0049] In some possible embodiments, the drone 1 is a multi-rotor drone 1. Preferably, it has at least four rotors which are evenly connected to the frame 11 and are horizontally arranged.

[0050] Preferably, in order to prevent the multi-rotor drone 1 from tipping over when landing, the landing gear 12 is a shock-absorbing landing gear 12;

[0051] The present invention can effectively realize pulling the safety net 10 in the air, with a simple structure and convenient operation. For the construction site environment, the operation range of the multi-rotor drone 1 is more flexible. The insertion and extraction of the pull rod of the bolt 23 are realized by controlling the rotation of the rocker arm 24 connected to the output shaft of the driving motor 25 at the bottom of the drone 1. When the pull rod of the bolt 23 is inserted into the hole of the bolt 23, the safety net 10 is pulled in the air through the hanging rope; when the drone 1 flies to the designated location and the pull rod of the bolt 23 is pulled out, the release of the safety net 10 is realized.

[0052] Embodiment 1:

[0053] As Figure 2 shown, in use, start 1 multi-rotor drone 1, drive the driving motor 25 through the release device on the remote control, control the rotation of the rocker arm 24 connected to the output shaft of the driving motor 25, so that the end of the bolt 23 away from the rocker arm 24 moves into the pin hole of the vertical plate 22 on the side away from the driving motor 25. Hook the hook on the hanging rope to one of the corners of the safety net 10. Additionally, place the ring on the hanging rope in the gap between the two vertical plates 22. Control the bolt 23 to pass through the ring on the hanging rope and enter the pin hole of the vertical plate 22 on the side away from the driving motor 25 through the driving motor 25, thereby realizing the mounting of the safety net 10 on the drone 1.

[0054] Manually assist to fully unfold the safety net 10, stretch the safety net 10 into the air, control the multi-rotor drone 1 to fly to the designated location at the construction site, and use the remote control to pull out the bolt 23 from the pin hole, thereby realizing the release of the safety net 10. Land the multi-rotor drone 1 on the ground. According to the same steps, use the drone 1 to pull the other corners of the safety net 10 to unfold the safety net 10, so as to realize the complete coverage of the areas such as the bare soil and construction waste that need to be covered by the safety net 10.

[0055] Embodiment 2:

[0056] As Figure 3As shown, during use, two multi-rotor unmanned aerial vehicles 1 are used to connect to two corner parts of the safety net with closely spaced mesh 10. Here, the two corner parts cannot be symmetric corner parts. Control the two multi-rotor unmanned aerial vehicles to pull the entire safety net with closely spaced mesh 10 into the air, adjust the flight postures of the two multi-rotor unmanned aerial vehicles 1 in the air, and fully unfold the safety net with closely spaced mesh 10 in the air. The two multi-rotor unmanned aerial vehicles 1 fly to the bare soil coverage area that needs to be covered at the construction site, lower the heights of the two multi-rotor unmanned aerial vehicles 1, make the other side of the safety net with closely spaced mesh 10 touch the ground first, and the two multi-rotor unmanned aerial vehicles 1 slowly move forward simultaneously to fully unfold the safety net with closely spaced mesh 10 in the horizontal direction. Control the remote controller to pull out the bolt 23 from the bolt hole to complete the delivery of the safety net with closely spaced mesh 10, thereby realizing the coverage of the bare soil by the safety net with closely spaced mesh 10.

[0057] Embodiment 3

[0058] During use, first spread out the safety net with closely spaced mesh 10, use four unmanned aerial vehicles 1 to connect to four corner parts of the safety net with closely spaced mesh 10 respectively, control the four unmanned aerial vehicles 1 to take off simultaneously, and then transport the unfolded safety net with closely spaced mesh 10 above the bare soil. Lower the heights of the four multi-rotor unmanned aerial vehicles 1, and simultaneously separate the safety net with closely spaced mesh 10 from the four unmanned aerial vehicles 1 through the release device, thereby completing the coverage of the bare soil in this area.

[0059] The present invention is not limited to the foregoing specific embodiments. The present invention extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
