Description

Technical Field

[0001] The utility model relates to the field of target technology, and in particular to a target device for unmanned aerial vehicle measurement which is easy to install. Background Art

[0002] Drone measurement is to use drones to carry optical cameras and process them to obtain the shape, size, position, characteristics and their relationships of the objects being photographed. The main task of drone measurement is to measure and produce topographic maps of various scales. Targets can be placed on the ground to facilitate drone measurement of precise locations.

[0003] Traditional targets are usually inserted into the ground at the measurement location through a sharp rod at the bottom. The target position usually needs to be detected from different positions, so the target needs to be placed for a long time.

[0004] The above device is in use. Due to the high dust content in the wild, the target is easily covered by dust after being placed for a long time, making it difficult for the drone camera to observe the target in time. Staff are often required to clean the target, which makes the measurement more cumbersome and requires high physical strength. Therefore, improvements are needed from staff. Utility Model Content

[0005] The purpose of the utility model is to overcome the long time consumed by drone measurement in the prior art and provide a target device for drone measurement that is easy to install;

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] include:

[0008] A protection box, wherein a mounting shell is fixedly connected to the back of the protection box, a battery is installed on the inner wall of the mounting shell, an electric telescopic rod is installed on the output end of the battery, and the tail of the electric telescopic rod is fixedly connected to the inner wall of the protection box, a target is fixedly connected to the front end of the electric telescopic rod, and the upper and lower sides of the back of the target are fixedly connected to sliding rods, the upper and lower sides of the inner wall of the protection box are fixedly connected to connecting tubes, and the surface of the sliding rod is slidably connected to the inner wall of the connecting tube, the left and right sides of the front of the protection box are fixedly connected to connecting rings, the middle of the connecting ring is rotatably connected to a rotating rod, the front of the rotating rod is fixedly connected to a protective door, the left and right sides of the rotating rod are connected to torsion springs, and the tail end of the torsion spring is connected to the inner wall of the connecting ring;

[0009] The bottom of the protection box is rotatably connected to a rotating shaft, the bottom of the rotating shaft is rotatably connected to a plug-in rod, the left and right sides of the top of the plug-in rod are fixedly connected to a first limit box, the inner bottom wall of the first limit box is connected to a first spring, the top of the first spring is connected to a first limit block, and the surface of the first limit block is slidably connected to the inner wall of the first limit box.

[0010] The left and right sides of the connecting rod are fixedly connected with a rotating ring, the surface of the rotating ring is rotatably connected with a limiting plate, the left and right sides of the top of the front side of the limiting plate are fixedly connected with a second limit box, the inner wall of the second limit box is connected with a second spring, the top of the second spring is connected with a second limit block, and round holes are provided on the top of the left and right sides of the connecting rod.

[0015] The technical solution provided by the utility model has the following technical effects:

[0016] 1. The utility model provides a target device for drone measurement which is easy to install. By using the target and the protective door together, the protective door is squeezed by the torsion spring so that the protective door is always rotated toward the protection box. When the target is extended, the target will press against the protective door and push it open. When the target is retracted, the protective door is squeezed by the torsion spring and automatically rotates and closes following the retraction of the target, so that the target is in a closed state when not in use, thereby reducing the area covered by sand and dust. This device is squeezed and rotated by the torsion spring, so that the protective door rotates due to the extension and retraction of the target, reducing the operating steps of the staff and having the effect of reducing physical exertion.

[0017] 2. The utility model provides a target device for drone measurement which is easy to install. By using a limiting plate in combination, the plug-in rod is inserted into the ground, so that the soil squeezes the limiting plate. The limiting plate can be rotated and unfolded, thereby increasing the resistance of the plug-in rod in the soil, which has the effect of reducing the probability of the target being hung by the wind.

DETAILED DESCRIPTION

[0027] See also Figures 1 to 7 , a target device for drone measurement that is easy to install; comprising:

[0028] A protection box 1, a mounting shell 2 is fixedly connected to the back of the protection box 1, a battery 3 is installed on the inner wall of the mounting shell 2, an electric telescopic rod 4 is installed on the output end of the battery 3, and the tail of the electric telescopic rod 4 is fixedly connected to the inner wall of the protection box 1, a target 5 is fixedly connected to the front end of the electric telescopic rod 4, and the upper and lower sides of the back of the target 5 are fixedly connected to the sliding rod 6, the upper and lower sides of the inner wall of the protection box 1 are fixedly connected to the connecting tube 7, and the surface of the sliding rod 6 is slidably connected to the inner wall of the connecting tube 7, the left and right sides of the front of the protection box 1 are fixedly connected to the connecting ring 8, the middle part of the connecting ring 8 is rotatably connected to the rotating rod 9, the front of the rotating rod 9 is fixedly connected to the protective door 10, the left and right sides of the rotating rod 9 are connected to the torsion spring 11, and the tail end of the torsion spring 11 is connected to the inner wall of the connecting ring 8;

[0029] The protective door 10 is in a state of being in contact with the protective box 1 when the torsion spring 11 is not squeezed, and when the protective door 10 is rotated, the torsion spring 11 is squeezed, so that the torsion spring 11 pushes the protective door 10 back to its original position;

[0030] When the target 5 is used for UAV measurement, the electric telescopic rod 4 is connected to the battery 3, so that the power of the battery 3 is transmitted to the electric telescopic rod 4, so that the electric telescopic rod 4 extends forward, and the electric telescopic rod 4 drives the target 5 at the front end to move forward, and the target 5 drives the sliding rod 6 at the rear end to slide on the inner wall of the connecting tube 7, so that the target 5 slides out of the inner wall of the protection box 1. When the target 5 overflows the protection box 1, the target 5 supports the protection door 10, and then moves the target 5 forward, so that the protection door 10 rotates and opens, and the protection door 10 drives the rotating rod 9 to rotate, and the rotating rod 9 drives the torsion springs 11 at both ends to rotate and squeeze. When the target 5 is not needed, the electric telescopic rod 4 shrinks, so that the electric telescopic rod 4 drives the target 5 at the front end to shrink toward the inner wall of the protection box 1. At this time, the protection door 10 shrinks through the target 5, so that the torsion spring 11 drives the protection door 10 to rotate, so that the protection door 10 fits on the front of the protection box 1, so that the protection door 10 intercepts dust when it is not in use;

[0031] The bottom of the protection box 1 is rotatably connected to a rotating shaft 12, the bottom of the rotating shaft 12 is rotatably connected to a plug rod 13, the left and right sides of the top of the plug rod 13 are fixedly connected to a first limit box 14, the inner bottom wall of the first limit box 14 is connected to a first spring 15, the top of the first spring 15 is connected to a first limit block 16, and the surface of the first limit block 16 is slidably connected to the inner wall of the first limit box 14;

[0032] When the target 5 is used for drone measurement, the plug rod 13 is inserted into the ground at the target position to fix the target 5, and then the target 5 is rotated, so that the protection box 1 drives the bottom rotating shaft 12 to rotate, so that the protection box 1 squeezes the first limit block 16, so that the first limit block 16 shrinks into the inner wall of the first limit box 14, and the first limit block 16 squeezes the first spring 15, and each rotation of ninety degrees makes the first spring 15 rebound, pushing the first limit block 16 into the hole at the bottom of the protection box 1, thereby fixing the target 5;

[0033] The left and right sides of the plug rod 13 are fixedly connected with a rotating ring 17, the surface of the rotating ring 17 is rotatably connected with a limiting plate 18, the left and right sides of the top of the front side of the limiting plate 18 are fixedly connected with a second limit box 19, the inner wall of the second limit box 19 is connected with a second spring 20, the top of the second spring 20 is connected with a second limit block 21, and the tops of the left and right sides of the plug rod 13 are provided with round holes;

[0034] When fixing the plug rod 13 in the soil, the plug rod 13 is inserted into the soil at the target location. At this time, the soil is squeezed into the inner groove of the limiting plate 18, and then the plug rod 13 is inserted downward, so that the soil is squeezed outward through the oblique edge of the inner groove of the limiting plate 18, so that the limiting plate 18 stretches out in the soil. When the limiting plate 18 is rotated ninety degrees, the second spring 20 pushes the second limit block 21, so that the second limit block 21 is inserted into the circular holes on the left and right sides of the plug rod 13, thereby fixing the limiting plate 18, thereby increasing the resistance of the plug rod 13 in the soil.

[0035] Working principle: the device is placed at the target location, and the plug rod 13 is inserted into the ground. When the plug rod 13 is inserted into the ground, the soil squeezes the limiting plate 18, so that the soil squeezes the limiting plate 19 outward, so that the limiting plate 18 rotates in the soil. After the limiting plate 19 rotates ninety degrees, the first spring 15 pushes the first limit block 16, so that the first limit block 16 is inserted into the circular holes on the left and right sides of the plug rod 13, thereby fixing the limiting plate 18. At this time, the limiting plate 18 is horizontally barred in the soil, thereby increasing the resistance of the plug rod 13 in the soil, and then rotating. The protective box 1 is moved so that the target 5 faces the position to be measured by the drone. When the drone needs to measure, the electric telescopic rod 4 is connected to the battery 3 to extend the electric telescopic rod 4, so that the target 5 moves outward and pushes the protective door 10, so that the protective door 10 is squeezed open, thereby exposing the target 5 to the outside, so that the drone can measure the position of the target 5. When not measuring, the electric telescopic rod 4 drives the target 5 to retract into the inner wall of the protective box 1, so that the torsion spring 11 squeezes and rotates the protective door 10 to the surface of the protective box 1, thereby closing the target 5 and preventing the target 5 from being covered by sand and dust.
