Description

Technical Field

[0001] The present invention belongs to the technical field of highway cross-section measurement, and more specifically, particularly relates to a highway cross-section measurement device based on an unmanned aerial vehicle-borne laser radar. Background Art

[0002] In the process of highway survey and design, especially in the reconstruction and expansion projects of existing highways, highway cross-section measurement devices are needed to improve the accuracy of cross-section measurement, so that the highway can meet the design safety requirements after construction, coordinate with the layout requirements of buildings and public facilities along the road, and improve the rationality of the design.

[0003] For example, in the patent with application number: CN202210527234.6, a highway cross-section measurement device based on an unmanned aerial vehicle laser radar is disclosed, including a body wing frame, a motor and a fan blade, the side wall of the body is fixedly provided with a wing frame at equal angles in the circumferential direction, and the end of the wing frame is fixedly installed with a motor, and the output end of the motor is fixedly installed with a fan blade; the upper surface of the movable seat is fixedly connected to the output end of the motor inside the body, and the lower surface of the movable seat is fixedly installed with a fixed frame, and the lower end of the fixed frame is movably connected with a movable leg; a rotating plate is fixedly installed on the shaft end of the roller, and the lower surface of the rotating plate is provided with flexible bristles; it can perform efficient shock absorption during use, and the lens can be automatically cleaned and defogged, thereby improving the measurement effect and measurement accuracy.

[0004] Based on the above, the currently used highway cross-section measurement devices still have the following problems: 1. Generally, there is a lack of bird-repelling structure, which makes it easy for drones to collide with birds when flying at high altitudes. When the wind is strong at high altitudes, it is impossible to remind the staff in time, making it inconvenient to retrieve the drone in time; 2. Although some laser measuring instruments are also installed on the buffer structure, when the drone drives the laser measuring instrument for measurement, the laser measuring instrument will move, reducing the measurement accuracy; 3. Drones are usually placed on the ground for takeoff. When there is a lot of loose dust or the ground is dry, the airflow generated by the drone taking off will impact the ground and draw the dust on the ground into the air, causing the dust to easily adhere to the drone and laser measuring instrument, which not only affects the measurement effect, but also increases the difficulty of subsequent cleaning.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the drone body drives the laser measuring instrument to move, the wind-powered reflective bird repeller can automatically rotate, which drives away birds and prevents them from approaching the drone body, thus avoiding collisions between the drone body and birds. When the drone body is flying, the wind-powered reflective bird repeller has the effects of rotation and slight shaking, which can automatically change the irradiation position of the reflective lens, thus improving the bird repeller effect. In addition, when the wind speed at high altitude is less than level five and meets the flight requirements, the circular mounting rod will only swing slightly and the conductive ring will not contact the U-shaped conductive frame; when the wind speed at high altitude is greater than level five and does not meet the flight requirements, the swing amplitude of the circular mounting rod becomes larger and the conductive ring can contact the U-shaped conductive frame; when the conductive ring contacts the U-shaped conductive frame, the alarm will work, which is convenient for reminding the staff that the wind speed at high altitude is strong, making it convenient for the staff to retract the drone body in time.

[0017] In the present invention, when the two T-shaped support frames are in an open state, the two T-shaped support frames can push the two movable positioning rods to move inward; when the two T-shaped support frames are in a stored state, the two spiral springs C can drive the two movable positioning rods to move outward; In addition, the resistance of the interference fit connection between the two T-shaped support frames and the two U-shaped connection seats is greater than the elastic force of the two spiral springs C plus the gravity of the drone body, the bird-repelling mechanism, the wind force detection mechanism and the laser measurement mechanism, ensuring that the two T-shaped support frames will not rotate automatically after being opened with force; the setting of the two circular limit shafts has a limiting effect on the rotation angle of the two T-shaped support frames, which is convenient for the opening and storage of the two T-shaped support frames; In addition, when the two T-shaped support frames push the two movable positioning rods to move inward, the inner ends of the two rubber positioning blocks are in close contact with the movable mounting frame, which plays a positioning role for the movable mounting frame, so that the laser measuring instrument is in a stable state when the drone body is flying, thereby ensuring the measurement accuracy; when the two coil springs C drive the two movable positioning rods to move outward, the inner ends of the two rubber positioning blocks are automatically separated from the movable mounting frame. At this time, the movable mounting frame has the effect of moving up and down under the action of the eight coil springs B, so that when the drone body is not in use, the laser measuring instrument has an automatic buffering effect, thereby avoiding damage to the laser measuring instrument due to collision during carrying or moving.

[0018] When the drone body of the present invention is not in use, the staff can place the drone body, the bird-repelling mechanism, the wind force detection mechanism, the laser measurement mechanism and the support mechanism in a protective storage box, which is convenient for the staff to carry through the circular gripping rod. At the same time, the stored drone body, the bird-repelling mechanism, the wind force detection mechanism, the laser measurement mechanism and the support mechanism are located between the protective storage box and the support plate, thereby achieving all-round protection. The airflow generated when the drone body takes off can be absorbed by the support plate and the inclined wind shield, thereby preventing the airflow generated when the drone body takes off from causing dust on the ground to fly.

At the same time, the drone body 100 after storage The human-machine body 100, the bird-repelling mechanism 200, the wind force detection mechanism 300, the laser measurement mechanism 400 and the support mechanism 500 are located between the protective storage box 605 and the support plate 601, thus achieving all-round protection. Furthermore, because the top of the support plate 601 is in contact with the two T-shaped support frames 502, and the inclined windshield 603 is fixedly installed on the top of the support plate 601, the airflow generated when the drone body 100 takes off can be absorbed by the support plate 601 and the inclined windshield 603, thus preventing the airflow generated when the drone body 100 takes off from causing dust on the ground to fly.

[0037] The specific usage and function of this embodiment are as follows: When the present invention is used, the drone body 100, the bird-repelling mechanism 200, the wind force detection mechanism 300, the laser measurement mechanism 400 and the support mechanism 500 are first taken out of the protective storage box 605, and then the two T-shaped support frames 502 are rotated outward to make the two T-shaped support frames 502 in an open state. When the two T-shaped support frames 502 are in an open state, the two T-shaped support frames 502 can push the two movable positioning rods 406 to move inward; when the two T-shaped support frames 502 push the two movable positioning rods 406 to move inward, the two T-shaped support frames 502 can push the two movable positioning rods 406 to move inward. When the drone body 100 moves inward, the inner ends of the two rubber positioning blocks 409 are in close contact with the movable mounting frame 403, which plays a positioning role for the movable mounting frame 403, so that when the drone body 100 is flying, the laser measuring instrument 404 is in a stable state, ensuring the measurement accuracy; then the two T-shaped support frames 502 are placed at the top center of the supporting plate 601, and then the drone body 100 is controlled to take off. The airflow generated when the drone body 100 takes off can be absorbed by the supporting plate 601 and the inclined windshield 603, so as to avoid the airflow generated when the drone body 100 takes off from driving the ground to fly dust; when the drone body 100 drives the laser measuring instrument 404 to move, the wind-powered reflective bird repellent 205 can automatically rotate, which plays a driving role on birds, prevents birds from approaching the drone body 100, and avoids the situation where the drone body 100 collides with birds; when the drone body 100 is flying, the wind-powered reflective bird repellent 205 has the effect of rotating and slightly shaking, and can automatically change the irradiation position of the reflective lens, thereby improving the bird repelling effect; when the drone body 100 is in the high altitude When the wind force is less than level 5 and meets the flight requirements, the circular mounting rod 203 will only swing slightly, and the conductive ring 305 will not contact the U-shaped conductive frame 303; when the wind force in the air is greater than level 5 and does not meet the flight requirements, the swing amplitude of the circular mounting rod 203 becomes larger, and the conductive ring 305 can contact the U-shaped conductive frame 303; when the conductive ring 305 contacts the U-shaped conductive frame 303, the alarm 302 works, which is convenient for reminding the staff that the wind force in the air is strong, so that the staff can retract the drone body 100 in time; After the measurement is completed, the staff will place the drone body 100, the bird-repelling mechanism 200, the wind force detection mechanism 300, the laser measurement mechanism 400 and the support mechanism 500 in the protective storage box 605, which is convenient for the staff to carry through the circular gripping rod 602. At the same time, the drone body 100, the bird-repelling mechanism 200, the wind force detection mechanism 300, the laser measurement mechanism 400 and the support mechanism 500 after storage are located between the protective storage box 605 and the support plate 601, achieving all-round protection. When the two T-shaped support frames 502 are in the storage When the two spiral springs C410 are in the state, the two movable positioning rods 406 can be driven to move outward; when the two spiral springs C410 drive the two movable positioning rods 406 to move outward, the inner ends of the two rubber positioning blocks 409 are automatically separated from the movable mounting frame 403. At this time, the movable mounting frame 403 has the effect of moving up and down under the action of the eight spiral springs B405, so that when the drone body 100 is not in use, the laser measuring instrument 404 has an automatic buffering effect, thereby preventing the laser measuring instrument 404 from being damaged due to collision during carrying or moving.
