Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a safe take-off and landing platform for unmanned aerial vehicles. Background Art

[0002] Before a drone takes off, it will first select a suitable take-off site. In addition to meeting the height and distance requirements of the measurement area, the take-off site must also meet the conditions of a flat ground and open and unobstructed surrounding sky. After meeting the above conditions, a take-off and landing platform carrying a drone is placed at a suitable take-off site, and the drone can be taken off. This can maximize the safety of the drone's take-off.

[0003] However, there are still some defects in the existing UAV landing and take-off platforms. For example, most of the existing UAV landing and take-off platforms are not provided with an adjustment device for adjusting their horizontal state. If aerial surveys are carried out on some complex and rugged terrains, such landing and take-off platforms often cannot be placed on the ground in a horizontal state, resulting in a poor posture of the UAV when taking off. In serious cases, the UAV may even tip over or deviate from the original take-off route and collide with surrounding obstacles, causing damage to the UAV and unnecessary losses. In addition, most of the existing UAV landing and take-off platforms are not provided with an aerial survey device for detecting obstacles in the surrounding sky, and most people will choose to observe whether there are obstacles in the surrounding sky with the naked eye. This method of observation with the naked eye is not rigorous enough and is prone to misjudgment. In addition, the distance between the obstacles in the surrounding sky and the take-off point is difficult to estimate, which will increase the probability of the UAV colliding with the obstacles in the surrounding sky when taking off, which may easily cause the UAV to fail to take off and then fall to the ground, causing irreparable damage to the UAV. Therefore, there is an urgent need for a UAV landing and take-off platform with a horizontal state adjustment function and an aerial survey function to solve the above problems. Utility Model Content

[0004] In order to solve the problems arising from the above-mentioned background technology, the purpose of the present invention is to provide a safe take-off and landing platform for unmanned aerial vehicles. The safe take-off and landing platform for unmanned aerial vehicles is provided with a take-off and landing plate, an adjustment component, and an aerial survey component. The adjustment component is used to solve the problem that the existing unmanned aerial vehicle take-off and landing platform cannot adjust its horizontal state. The aerial survey component is used to replace the traditional method of judging the take-off environment of the unmanned aerial vehicle by naked eye observation.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A safe take-off and landing platform for unmanned aerial vehicles comprises an unmanned aerial vehicle, wherein the safe take-off and landing platform for unmanned aerial vehicles comprises a take-off and landing plate providing a take-off and landing point for the unmanned aerial vehicle, an adjustment component, and an aerial survey component, wherein the adjustment component is arranged on the bottom surface of the take-off and landing plate, and the aerial survey component is arranged on the surface of the take-off and landing plate, and the aerial survey component comprises a central column, a graduated tape measure, and a laser pen, wherein the central column is arranged at the center of the surface of the take-off and landing plate, one end of the graduated tape measure is connected to the central column, and the other end of the graduated tape measure is connected to the laser pen, and the laser pen makes a circular motion around the central column through the graduated tape measure and emits laser upward to detect obstructions above the surrounding area.

[0007] Preferably, the adjustment assembly includes a plurality of tripod rods and a plurality of adjustment screws, one ends of the plurality of tripod rods are arranged in a triangular shape and fixed to the bottom surface of the lifting and lowering platform, the other ends of the plurality of tripod rods are spirally connected to one ends of the plurality of adjustment screws, and the other ends of the plurality of adjustment screws are connected to the ground.

[0008] Preferably, the tripod rod is provided with an empty groove inside, the inner side wall of the empty groove is provided with an internal thread, the outer side wall of the adjusting screw is provided with an external thread, and the tripod rod and the adjusting screw are connected to the inside of the empty groove through the matching spirals of the internal thread and the external thread.

[0009] Preferably, a circular level is fixedly mounted on the surface of the landing plate, a circular level bubble and a correction circle are arranged inside the circular level, and the circular level cooperates with the adjustment component to achieve leveling adjustment of the landing plate.

[0010] Preferably, one end of the graduated tape measure is fixedly connected to the central column via a ring, and the other end of the graduated tape measure is bound and connected to the laser pen via a binding rope.

[0011] The beneficial effects of the utility model are:

[0012] (1) The aerial survey assembly of the utility model includes a center column, a scale tape, and a laser pen. The center column is arranged at the center of the surface of the take-off and landing platform. One end of the scale tape is fixedly connected to the center column through a ring, and the other end of the scale tape is bound to the laser pen through a binding rope. The laser pen can make a circular motion with the center column as the center through the scale tape, and emit laser upward to detect whether there are any obstructions in the surrounding sky. Then, the distance between the center column and the laser pen (that is, the distance between the take-off point of the drone and the obstructions in the surrounding sky) is obtained through the scale tape, and the surrounding environment is accurately detected to facilitate an accurate judgment of the take-off environment of the drone. In this way, the traditional method of using naked eye observation and judgment is replaced, and the probability of the drone colliding with the surrounding obstructions is reduced to the greatest extent, so that the take-off process of the drone can be carried out smoothly, which can effectively avoid the situation where the drone collides with the surrounding obstructions during take-off;

[0013] (2) The surface of the take-off and landing platform of the utility model is also provided with a circular level. The adjustment assembly includes a plurality of tripod rods and a plurality of adjustment screws. The height of the tripod rods is adjusted by rotating and twisting the adjustment screws and the horizontal state of the take-off and landing platform is adjusted by cooperating with the circular level. Thus, the take-off and landing platform can be kept in a relatively horizontal state. Even in some complex and rugged terrains, it can effectively ensure that the UAV can take off in a good posture, avoiding the situation where the UAV tipped over or deviated from the original take-off route and collided with surrounding obstructions due to the uneven take-off and landing platform during take-off. This can maximize the success rate of the UAV take-off and prevent the UAV from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] As attached Figure 1-2As shown, an embodiment of the utility model provides a safe take-off and landing platform for an unmanned aerial vehicle, including an unmanned aerial vehicle 1. The safe take-off and landing platform for the unmanned aerial vehicle includes a take-off and landing platform 2 that provides a take-off and landing point for the unmanned aerial vehicle 1, an adjustment component 3, and an aerial survey component 4. The adjustment component 3 is arranged on the bottom surface of the take-off and landing platform 2, and the aerial survey component 4 is arranged on the surface of the take-off and landing platform 2. The aerial survey component 4 includes a central column 401, a scale tape 402, and a laser pen 403. The central column 401 is arranged at the center of the surface of the take-off and landing platform 2, one end of the scale tape 402 is connected to the central column 401, and the other end of the scale tape 402 is connected to the laser pen 403. The laser pen 403 moves in a circle around the central column 401 through the scale tape 402 and emits a laser 4031 upward to detect obstructions 5 above the surrounding area.

[0019] Specifically, the take-off and landing platform 2 is configured to be made of stainless steel material. Stainless steel material has high strength and hardness, can withstand a large load, and is very suitable as a support platform for the drone 1.

[0020] Specifically, the graduated tape measure 402 is made of a soft material to facilitate operations such as extension or folding.

[0021] The adjustment assembly 3 includes a plurality of tripod rods 301 and a plurality of adjustment screws 302. One ends of the plurality of tripod rods 301 are fixed to the bottom surface of the lifting and lowering platform 2 in a triangular shape, and the other ends of the plurality of tripod rods 301 are spirally connected to one ends of the plurality of adjustment screws 302. The other ends of the plurality of adjustment screws 302 are connected to the ground 6.

[0022] Specifically, the tripod rod 301 and the adjusting screw 302 are both made of stainless steel. The stainless steel material has excellent corrosion resistance, can resist the erosion of most chemicals in the external environment, and is not easy to rust.

[0023] An empty slot 3011 is provided inside the tripod rod 301, and an inner wall of the empty slot 3011 is provided with an internal thread 3012. An outer wall of the adjusting screw 302 is provided with an external thread 3021. The tripod rod 301 and the adjusting screw 302 are connected to the inside of the empty slot 3011 through the matching spirals of the internal thread 3012 and the external thread 3021.

[0024] A circular level 201 is fixedly installed on the surface of the landing platform 2. A circular level bubble 2011 and a correction circle 2012 are arranged inside the circular level 201. The circular level 201 cooperates with the adjustment component 3 to achieve leveling adjustment of the landing platform 2.

[0025] When the utility model is implemented, the adjustment component 3 includes a plurality of tripod rods 301 and a plurality of adjustment screws 302. When the adjustment screw 302 is twisted clockwise, the tripod rod 301 spirally connected thereto will translate upward in the empty slot 3011. When the adjustment screw 302 is twisted counterclockwise, the tripod rod 301 spirally connected thereto will translate downward in the empty slot 3011, thereby adjusting the height of the tripod rod 301. While observing the circular level 201, the plurality of adjustment screws 302 are twisted to make the plurality of tripod rods 301 reach the same height so that the lifting and landing platform 2 can be kept in a relatively horizontal state to the greatest extent. At this time, by observing the circular level bubble 201 in the circular level 201, the height of the tripod rod 301 can be adjusted. 1, if the circular vial 2011 is located inside the correction circle 2012, it means that the take-off and landing platform 2 is in a horizontal state; if the circular vial 2011 is located outside the correction circle 2012, it means that the take-off and landing platform 2 is in a non-horizontal state, continue to twist several adjusting screws 302 for fine adjustment, so that the circular vial 2011 is located inside the correction circle 2012, and the take-off and landing platform 2 is kept in a horizontal state. The utility model enables the entire take-off and landing platform to keep the take-off and landing platform 2 in a horizontal state in some complex and rugged terrains through the cooperation of the adjustment component 3 and the circular level 201, so that the UAV 1 can perform take-off and landing operations in a good posture.

[0026] One end of the graduated tape measure 402 is fixedly connected to the central column 401 via a ring 7 , and the other end of the graduated tape measure 402 is bound and connected to the laser pen 403 via a binding rope 5 .

[0027] Specifically, the tape measure 402 is provided with a distance scale, and the overall length of the tape measure 402 can be adjusted according to actual needs. The binding rope 8 can stably bind the tape measure 402 and the laser pen 403 to prevent the laser pen 403 from being offset during use and thus affecting the detection effect.

[0028] Reference Figure 1-2 The working process of the utility model of a safe take-off and landing platform for unmanned aerial vehicles is as follows:

[0029] When working, first pre-assemble the UAV safe take-off and landing platform and carry the UAV 1, then place the platform on the ground of the target detection area, observe the position of the circular level bubble 2011 inside the circular level 201 on the surface of the take-off and landing platform 2, if the circular level bubble 2011 is located outside the circle of the correction circle 2012, it means that the take-off and landing platform 2 is in a non-horizontal state, then twist several adjusting screws 302 in the clockwise direction, so that several tripod rods 301 move upward in the empty slots 3011 The circular vial 2011 is observed again. If the circular vial 2011 is located inside the calibration circle 2012, it indicates that the landing platform 2 is in a horizontal state, and the landing platform 2 is leveled. If the circular vial 2011 is still outside the calibration circle 2012, the adjusting screw 302 is twisted several times to fine-tune until the circular vial 2011 is located inside the calibration circle 2012.

[0030] After completing the leveling adjustment of the take-off and landing platform 2, a navigation test of the UAV 1 is carried out. The graduated tape measure 402 connected to the central column 401 is stretched horizontally to a set distance. The other end of the graduated tape measure 402 is connected to a laser pen 403. The staff turns on the laser pen 403 to emit a laser 4031 upward, and holds the laser pen 403 in a circle with the graduated tape measure 402 as the center, if the laser 4031 does not irradiate the shielding object 5, it means that the area is suitable for the UAV 1 to take off. If the laser 4031 irradiates the shielding object 5, it means that the area is not suitable for the UAV 1 to take off, and the location can be changed.

[0031] The present invention has been described in detail above. The above description is only the preferred working process of the present invention and cannot limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope of the present invention.
