Description

Technical Field

[0001] This application relates to the technical field of unmanned aerial vehicle (UAV) layout equipment, and particularly to a UAV-based layout device. Background Art

[0002] The UAV layout technology refers to the process of using UAVs to quickly locate, determine height, and positioning angle on-site, and transmit data to the corresponding software system for processing and calculation, ultimately generating control points and ground markers. This technology combines the flexibility of UAVs and the advantages of high-precision positioning technology, and is widely used in multiple fields such as surveying and mapping, construction, and agriculture.

[0003] Currently, when using UAV layout technology to survey a mountain, before conducting UAV layout on the mountain, it is necessary to place layout markers at appropriate positions on the mountain with reasonable density, and then control the UAV to fly. Through multiple layout markers placed on the mountain, the situation of the mountain can be surveyed and measured.

[0004] However, currently, it is necessary to manually place layout markers on the mountain. The accuracy of manually placing layout markers is relatively low, and the placement efficiency is also low, which will affect the efficiency of surveying the mountain.

[0005] Therefore, there is an urgent need for a UAV layout device that can quickly place layout markers on the mountain. Summary of the Utility Model

[0006] This application provides a UAV-based layout device that can quickly place layout markers on the mountain, thereby effectively improving the efficiency of surveying the mountain.

[0007] This application provides a UAV-based layout device, adopting the following technical solution:

[0008] A UAV-based layout device is arranged at the bottom of the UAV, and the bottom of the UAV has several support feet, including a body, a cover, several support members, and a placement component;

[0009] The interior of the body has a cavity for storing layout markers, and the cavity penetrates through one side of the body to form an opening for the layout markers to enter and exit; the cover is arranged outside the body, is movably connected to the body, and can control the opening and closing of the opening;

[0010] The lofting marker is a spherical structure. Below the cavity inside the body, there is also a feeding channel and a discharging channel for a single lofting marker to move through. One end of the feeding channel communicates with the cavity, one end of the discharging channel communicates with the other end of the feeding channel, and the other end of the discharging channel penetrates the bottom of the body and communicates with the space below the body;

[0011] The support member is elastic. The support member is arranged at one end of the discharging channel close to the feeding channel. After the lofting marker moves along the feeding channel and enters the discharging channel, several support members support the lofting marker from below; after the support member undergoes elastic deformation, the lofting marker can enter the discharging channel;

[0012] The placing assembly is arranged inside the body, above the discharging channel, and there is an installation space for installing the placing assembly inside the body; the placing assembly includes a cylinder and a piston rod, and the installation space communicates with the discharging channel; the cylinder can control the piston rod to move along the extending direction of the discharging channel. During the process that the cylinder controls the piston rod to move downward, the piston rod can contact the lofting marker above several support members.

[0013] By adopting the above technical solution, before using the unmanned aerial vehicle, the user first loads a sufficient number of lofting markers into the cavity through the opening; then, after controlling the unmanned aerial vehicle to fly to the position where the lofting is to be marked and making the unmanned aerial vehicle land on the mountain, then control the placing assembly to control the piston rod to move, so that the lofting marker supported by the support member can be forced to deform the support member and leave through the discharging channel, land on the mountain and can partially sink into the mountain, improving the position stability of the lofting marker after being placed on the mountain, so that the lofting marker can be quickly placed on the mountain, and thus the efficiency of surveying and mapping the mountain can be effectively improved.

[0014] Optionally, the bottom of the cavity is in a flared shape towards the direction close to the feeding channel.

[0015] By adopting the above technical solution, it is convenient for the lofting markers in the cavity to enter the feeding channel, so that the lofting markers can continuously complete feeding through the feeding channel to facilitate the subsequent placement of the lofting markers.

[0016] Optionally, the extending direction of the feeding channel is a spiral line and encloses the placing assembly.

[0017] By adopting the above technical solution, the process of the lofting marker moving along the feeding channel can be made smoother, reducing the probability of the lofting marker getting stuck in the feeding channel.

[0018] Optionally, it further includes an elastic buffer member disposed at the communication between the installation space and the discharge channel; the buffer member is located above the lofting marker above several of the support members, and the piston rod can contact the buffer member when moving downward.

[0019] By adopting the above technical solution, when the placing assembly applies a force to the lofting marker through the piston rod to drive it to leave along the discharge channel, the buffer member can play a buffering effect between the two, thereby reducing the probability of damage to the piston rod and the lofting marker during the above process.

[0020] Optionally, it further includes several first elastic members; the buffer member is slidably connected to the machine body along the extending direction of the discharge channel and can slide in and out of the discharge channel; both ends of the first elastic member are respectively connected to the machine body and the buffer member, and can drive the buffer member to slide upward to the limit position and stay.

[0021] By adopting the above technical solution, it can facilitate the buffer member to transfer the impact force of the piston rod to the lofting marker, so that the lofting marker can fall onto the mountain body under a certain force and partially sink into the mountain body; at the same time, the buffer member can quickly reset after transmitting the impact, facilitating the placement of the next lofting marker.

[0022] Optionally, it further includes a sleeve disposed at the bottom of the machine body; the inside of the sleeve has a protection channel adapted to the lofting marker, the protection channel communicates with the discharge channel, and the extending direction of the protection channel is parallel to the extending direction of the discharge channel.

[0023] By adopting the above technical solution, the sleeve can play a protective role in the process of the lofting marker leaving the machine body and falling onto the mountain body, reducing the influence of external factors on the landing point of the lofting marker on the mountain body, thereby effectively improving the placement accuracy of the lofting marker;

[0024] Optionally, it further includes several second elastic members, the sleeve is slidably connected to the machine body, and the sliding direction of the sleeve is parallel to the extending direction of the protection channel; both ends of the second elastic member are respectively connected to the machine body and the sleeve, and can drive the sleeve to slide downward to the limit position, and at this time the bottom of the sleeve is lower than the support feet.

[0025] By adopting the above technical solution, the sleeve can adapt to different terrains on the mountain body, facilitating the landing of the drone on different terrains on the mountain body, reducing the influence of the sleeve during this process, and at the same time enabling it to maintain a protective effect on the delivery of the lofting marker.

[0026] Optionally, a plurality of ventilation openings are formed in the sleeve, and two ends of each ventilation opening communicate with the protection channel and the outer space of the sleeve respectively.

[0027] By adopting the above technical solution, the protection channel can be kept communicating with the outside during the process of placing the lofting marker, so that the internal and external air pressures are kept balanced, and the probability that the process of the lofting marker falling due to the air pressure difference is affected is reduced.

[0028] To sum up, the present application includes at least one of the following beneficial effects:

[0029] 1. It can effectively improve the accuracy of the lofting marker, and at the same time can quickly place the lofting marker on the mountain body, so as to effectively improve the efficiency of surveying and mapping the mountain body;

[0030] 2. It can improve the position stability of the lofting marker after being placed on the mountain body, and at the same time can adapt to different terrains of the mountain body, so that the lofting marker can be stably and reliably placed;

[0031] 3. It can reduce the probability of damage to the lofting marker during the placement process, and at the same time can enable the lofting marker to be stably loaded one by one, improving the reliability of repeatedly placing the lofting marker on the mountain body by the unmanned aerial vehicle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] The following will further describe the present application in detail Figures 1-3 with reference to the accompanying drawings.

[0037] An embodiment of the present application discloses a lofting device based on a drone. The drone carries a certain amount of lofting markers, and then by controlling the drone to fly and move on the mountain body, the lofting markers are placed at the required positions on the surface of the mountain body, facilitating subsequent lofting surveying through multiple lofting markers placed on the surface of the mountain body by the drone.

[0038] Referring to Figure 1 and Figure 2 The lofting device is fixedly installed at the bottom of the drone 1. The bottom of the drone 1 also has several support feet 11 for its stable landing, and the lofting device is surrounded by several support feet 11. In this embodiment, since the drone 1 is an existing technology in the art, it will not be elaborated herein, and it is only briefly shown in the drawings.

[0039] Referring to Figure 2 and Figure 3 The lofting device includes a body 2, a cover 3, several support members 4, and a placement assembly 5.

[0040] The body 2 is generally in a cylindrical structure. One end in the axial direction of the body 2 is fixedly connected to the bottom of the drone 1, and the axis of the body 2 is vertical; when the drone 1 lands on a plane, there is a gap between the bottom of the body 2 and the plane.

[0041] A cavity 21 for carrying the lofting marker 10 is provided at a position near the top of the body 2 inside the body 2. The overall shape of the cavity 21 is cylindrical, and the axis of the cavity 21 coincides with the axis of the body 2. In this embodiment, it is preferred that the shape of the lofting marker 10 is spherical; since the lofting marker 10 is an existing technology in the art, it will not be elaborated herein, and it is only briefly shown in the drawings.

[0042] An opening 22 for the lofting marker 10 to enter and exit is formed through one side of the body 2 along the radial direction of the body 2, allowing the user to replenish the lofting marker 10 into the cavity 21 or take out the lofting marker 10 in the cavity 21 through the opening 22.

[0043] Referring to Figure 1 and Figure 3 The cover 3 is generally in an arc-shaped plate structure. The cover 3 is installed on the outside of the body 2. The cover 3 is movably connected to the body 2, and the relative movement of the cover 3 with respect to the body 2 can control the opening and closing of the opening 22. In this embodiment, it is preferred that one side of the arc track of the cover 3 is rotatably connected to the body 2, and the rotation axis of the cover 3 is parallel to the axis of the body 2.

[0044] When the control cover 3 rotates towards the opening 22 to the extreme position, the arc surface of the cover 3 will be in contact with and against the outer side surface of the body 2. At this time, the cover 3 can cover the opening 22 to prevent substances from passing in and out through the opening 22; when the control cover 3 rotates away from the opening 22 to the extreme position, the opening 22 will be in an open state, facilitating the user to control the access of the lofting marker 10. In this embodiment, preferably, a lock is further installed on the cover 3 so that it can be fixed in a relative position with the body 2 after rotating towards the opening 22 to the extreme position; since the lock with the above functions is a common prior art, it will not be elaborated here, and it is only briefly shown in the drawings.

[0045] Referring to Figure 2 and Figure 3 , below the cavity 21 inside the body 2, a loading channel 23 for loading the lofting marker 10 and a discharging channel 24 for discharging the lofting marker 10 are further provided, and both the loading channel 23 and the discharging channel 24 can only allow the lofting marker 10 to move one by one along their extending directions.

[0046] The discharging channel 24 extends downward along the axis direction of the body 2 and penetrates the bottom of the body 2, and the axis of the discharging channel 24 coincides with the axis of the body 2, so that the lofting marker 10 entering the discharging channel 24 can move along the discharging channel 24 under its own gravity and leave the body 2.

[0047] The extending direction of the loading channel 23 is a spiral line. One end at the top of the loading channel 23 communicates with the bottom of the cavity 21, and the other end at the bottom of the loading channel 23 communicates with one side at the top of the discharging channel 24, so that the lofting marker 10 in the cavity 21 can first enter the loading channel 23 and then enter the discharging channel 24 through the loading channel 23.

[0048] Further, preferably, the bottom of the cavity 21 is in a necked shape towards the position close to the top of the loading channel 23, facilitating the movement of the lofting marker 10 in the cavity 21 into the loading channel 23 under its own gravity to improve the continuity of loading the lofting marker 10. In this embodiment, preferably, the bottom end face of the cavity 21 is an inclined plane, and the end close to the top of the loading channel 23 is the lower side of the inclination.

[0049] A number of support members 4 are all installed on the groove wall at the top of the discharging channel 24, and the number of support members 4 is circumferentially arrayed with the axis of the discharging channel 24 as the axis.

[0050] When the lofting marker 10 enters the discharging channel 24 through the loading channel 23, a number of support members 4 will support the lofting marker 10 below it to prevent it from directly moving away through the discharging channel 24 under its own gravity.

[0051] The support member 4 is elastic. After a certain downward acting force is applied to the lofting marker 10 supported by a plurality of support members 4, the support member 4 can be elastically deformed, enabling the lofting marker 10 to pass downward through between the plurality of support members 4 and then move away through the discharge channel 24. In this embodiment, it is preferred that the support member 4 is made of rubber material.

[0052] The machine body 2 is provided with an installation space 25 for installing the placing assembly 5 above the discharge channel 24. The installation space 25 is located below the cavity 21, surrounded by the feeding channel 23, and its bottom communicates with the discharge channel 24.

[0053] The placing assembly 5 includes a cylinder 51 and a piston rod 52. The cylinder 51 is fixedly installed at a position in the installation space 25 away from the discharge channel 24. The piston rod 52 is movably installed on the cylinder 51, and the end of the piston rod 52 can enter and exit the discharge channel 24 during the movement process. In this embodiment, it is preferred that the cylinder 51 can be remotely controlled by the user. Since both the cylinder 51 and the piston rod 52 are common existing technologies, that is, the above-mentioned placing assembly 5 is a common existing technology, so it will not be elaborated here, and only a brief representation is made of it in the drawings.

[0054] The machine body 2 is also provided with a buffer member 6 and a plurality of first elastic members 7 at the position where the installation space 25 communicates with the discharge channel 24.

[0055] The buffer member 6 is slidably connected to the machine body 2, and the sliding direction of the buffer member 6 is parallel to the axis of the machine body 2; when the buffer member 6 slides upward to the limit position, the space between the buffer member 6 and the plurality of support members 4 is just enough for a lofting marker 10 to stay. At this time, the plurality of support members 4 support the lofting marker 10 below, and at this time, the buffer member 6 is located above the lofting marker 10, and the space between the buffer member 6 and the plurality of support members 4 is only enough for the lofting marker 10 to enter and stay alone.

[0056] Both ends of the first elastic member 7 are fixedly connected to the buffer member 6 and the machine body 2 respectively, and can make the buffer member 6 have a tendency to slide upward to the limit position and stay. In this embodiment, it is preferred that the first elastic member 7 is a tension spring, and the first elastic member 7 is installed above the buffer member 6.

[0057] The buffer member 6 is elastic. In this embodiment, it is preferred that the buffer member 6 is made of rubber material.

[0058] When the cylinder 51 drives the piston rod 52 to move downward to the limit position, the end of the piston rod 52 will drive the buffer member 6 to slide downward a certain distance against the acting force of the first elastic member 7. At this time, the piston rod 52 will apply a downward acting force on the lofting marker 10 through the buffer member 6, driving the lofting marker 10 to squeeze several support members 4 to move downward and away. And at this time, the lofting marker 10 has a certain speed when leaving the body 2, and can partially sink into the mountain body after falling onto the mountain body, having a certain positioning effect.

[0059] When the cylinder 51 drives the piston rod 52 to move upward to the limit position, there is a distance between the end of the piston rod 52 and the buffer member 6 at this time; each time the cylinder 51 is controlled, it will control the piston rod 52 to move back and forth once, and normally the piston rod 52 will maintain the state of moving upward to the limit position.

[0060] A sleeve 8 and several second elastic members 9 are also installed at the bottom of the body 2.

[0061] The sleeve 8 is integrally in the structure of a hollow cylinder. The sleeve 8 is slidably connected to the bottom of the body 2. The axis of the sleeve 8 coincides with the axis of the body 2, and the sliding direction of the sleeve 8 is parallel to the axis of the body 2.

[0062] The inside of the sleeve 8 has a protection passage 81 for the lofting marker 10 to pass through. The overall shape of the protection passage 81 is also cylindrical, and the axis of the protection passage 81 coincides with the axis of the sleeve 8; during the process of the sleeve 8 sliding relative to the body 2, the protection passage 81 remains in communication with the bottom of the discharge passage 24. The lofting marker 10 moving away through the discharge passage 24 can enter the protection passage 81 and then continue to move through the protection passage 81.

[0063] When the sleeve 8 slides upward relative to the body 2 to the limit position, the position where the bottom of the sleeve 8 is located will be higher than the position where the bottom of the support foot 11 is located at this time; when the sleeve 8 slides downward relative to the body 2 to the limit position, the position where the bottom of the sleeve 8 is located will be lower than the position where the bottom of the support foot 11 is located at this time.

[0064] The two ends of the second elastic member 9 are respectively fixedly connected to the body 2 and the sleeve 8, enabling the sleeve 8 to have a tendency to slide downward relative to the body 2 to the limit position and remain. In this embodiment, preferably, the second elastic member 9 is a compression spring, and the second elastic member 9 is installed above the sleeve 8.

[0065] When the drone 1 is in a flying state, the second elastic member 9 can drive the sleeve 8 to slide downward relative to the body 2 to the limit position and remain; when the drone 1 lands on the mountain body, the bottom of the sleeve 8 will abut against the mountain body and slide upward relative to the body 2 against the acting force of the second elastic member 9 until several support feet 11 are all in contact with the mountain body surface, enabling the drone 1 to land smoothly on the surface of the mountain body.

[0066] Further, a plurality of air vents 82 are formed on the circumferential side of the sleeve 8. Both ends of each air vent 82 communicate with the protection channel 81 and the circumferential space of the sleeve 8 respectively, so that the air pressure inside and outside the sleeve 8 is balanced. When the bottom of the sleeve 8 is blocked by the soil after contacting the soil, when the setting-out marker 10 enters the protection channel 81 under the action of the placing assembly 5 and lands on the soil surface to complete the placement, the air flow generated by the movement of the setting-out marker 10 can smoothly discharge through the air vents 82, reducing the influence of the air pressure difference on the downward movement of the setting-out marker 10. In this embodiment, preferably, the air vents 82 are arranged in a circumferential array on the sleeve 8 with the axis of the sleeve 8 as the axis.

[0067] The implementation principle of a setting-out device based on a drone according to an embodiment of the present application is as follows:

[0068] First, open the cover 3, load a sufficient number of setting-out markers 10 into the cavity 21 through the opening 22, and then close the cover 3. At this time, the setting-out markers 10 in the cavity 21 can move one by one through the feeding channel 23 to the discharging channel 24, and the foremost setting-out marker 10 will stay above a plurality of support members 4.

[0069] Then, control the drone 1 to fly to and land at the required position on the mountain surface. During the landing process, when the bottom of the sleeve 8 contacts the mountain surface, the sleeve 8 will receive an upward acting force to overcome the second elastic member 9 and slide upward until a plurality of support feet 11 all contact the surface of the mountain, so that the drone 1 lands stably on the mountain surface.

[0070] Next, control the placing assembly 5. The cylinder 51 will drive the piston rod 52 to move, and apply a downward acting force to the setting-out marker 10 above a plurality of support members 4 through the buffer member 6, so that the setting-out marker 10 continues to move downward and lands on the soil to complete the placement. The process of placing the setting-out marker 10 at other positions on the mountain is repeated in this cycle.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
