Description

Technical Field

[0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a drone support frame for environmental monitoring. Background Art

[0002] Environmental monitoring is to track changes in environmental quality and determine the level of environmental quality by testing the content and emissions of various substances that have an impact on humans and the environment, providing a basis and guarantee for environmental management, pollution control and other work. Simply put, understanding the environmental level and conducting environmental monitoring are the prerequisites for carrying out all environmental work. Environmental monitoring usually includes background investigation, determining plans, optimizing locations, on-site sampling, sample transportation, experimental analysis, data collection, analysis and synthesis, etc. In general, it is a process of obtaining information through planning-sampling-analysis-synthesis.

[0003] Environmental monitoring is mostly carried out by drones, which are usually equipped with support frames. The support frames play an important role in the take-off and landing of drones.

Thanks to the arrangement of the extension shaft 3, the two groups of bearing base plates 1 can be pulled in opposite directions, so that the extension shaft 3 extends out from the bearing base plate 1, and the bearing base plate 1 and the extension shaft 3 are fixed by screwing the cross bolt into the threaded hole 301, which is convenient for adapting to the installation requirements of different drones and has strong applicability.

[0027] A sliding groove 102 is provided on one side of the lower end surface of the two groups of the bearing base plates 1, and a group of sliding shafts 5 are fixedly arranged in the sliding groove 102. A sliding block 501 is slidably installed on the outer edge surface of the sliding shaft 5. The lower end surface of the sliding block 501 extends out of the sliding groove 102 and is symmetrically fixedly connected with two groups of connecting ears 6 in the center. The connecting ear 6 is a plate structure with an arc-shaped structure at one end, and a group of first springs 502 mounted outside the sliding shaft 5 are hingedly installed between the two sides of the sliding block 501 and the end of the sliding groove 102.

[0028] Specifically, a group of circular shafts are movably arranged between the two groups of connecting ears 6, and a U-shaped support frame 7 is movably arranged on the outer edge surface of the circular shaft, and roller bearings are arranged at the connection between the outer edge surface of the circular shaft, the U-shaped support frame 7 and the connecting ear 6.

A placement bin for movably installing the extension column 1001 is opened in the two groups of the support columns 10, and a buffer spring is hingedly provided between the bottom of the placement bin and the extension column 1001 (in specific implementation, the end of the extension column 1001 away from the bearing base plate 1 is movably connected with a universal wheel through a pin shaft. When the UAV lands, the universal wheel can abut the ground, so that the buffer spring installed in the extension column 1001 abuts the ground, which is convenient for further enhancing the buffering function, better protecting the internal parts of the UAV, and further improving the service life of the UAV).

[0032] Specifically, two groups of rectangular grooves 19 are symmetrically opened on both sides of the bearing base plate 1, and two groups of anti-tilt devices 11 are symmetrically arranged on both sides of the bearing base plate 1, a roller 20 is fixedly arranged in the rectangular groove 19, and an adjustment block is slidably installed on the outer edge surface of the roller 20, and a rectangular groove 19 extends from the fast adjustment side and two groups of ear plates 2001 are symmetrically fixedly connected in the center.

[0033] Specifically, the anti-roll device 11 includes a support rod 12 and an extension rod 13, a movable shaft is installed between the two groups of ear plates 2001, a round hole is opened in the extension rod 13 for matching the movable shaft installation, and one end of the extension rod 13 extends into the support rod 12 and is fixedly connected with an abutment plate 1301, support feet 1201 are constructed on both sides of the lower end surface of the support rod 12, and a shock-absorbing chamber is opened in the support rod 12, and a group of shock-absorbing springs 14 are hingedly arranged between the bottom of the shock-absorbing chamber and the lower end surface of the abutment plate 1301. Thanks to the setting of the support feet 1201, when the drone is landing, the abutment plate 1301 connected to the extension rod 13 squeezes the shock-absorbing spring 14, so that the shock-absorbing spring 14 is deformed to provide buffering, and at the same time the support feet 1201 abut the ground to prevent rollover during landing, which is convenient for providing anti-roll protection and has strong practicality.

[0034] Specifically, vertical plates 15 are fixedly provided on both sides of the upper end surface of the supporting base plate 1 , a through slot 1501 is centrally provided in the vertical plate 15 , and a rotating wheel 16 is provided on the upper end surface of the vertical plate 15 , and the rotating wheel 16 is connected to a group of adjustment shafts 1601 movably provided in the through slot 1501 .

[0035] Specifically, a movable block is threadedly installed on the outer edge surface of the adjusting shaft 1601, a through slot 1501 extends from one side of the movable block and is fixedly connected to an adjusting plate 1602, a fixed plate 17 is arranged below the adjusting plate 1602, and two groups of fixed shafts 18 passing through the adjusting plate 1602 are symmetrically arranged on the upper end surface of the fixed plate 17, and a third spring 1801 sleeved on the outside of the fixed shaft 18 is hingedly arranged between the upper end surface of the fixed plate 17 and the lower end surface of the adjusting plate 1602 (in specific implementation, the rotating wheel 16 can be rotated to make the adjusting shaft 1601 rotate to drive the movable block to move in the through slot 1501, so that the adjusting plate 1602 moves up and down, driving the fixed plate 17 to move up and down, and the lower end surface of the fixed plate 17 abuts against the top of the drone, so as to improve the firmness of the drone fixation).

[0036] Working principle: When using the environmental monitoring drone support frame, the two sets of bearing base plates 1 can be pulled in opposite directions to make the extension shaft 3 extend from the bearing base plate 1, and the cross bolts are screwed into the threaded holes 301 to fix the bearing base plate 1 and the extension shaft 3, so as to adapt to the installation requirements of different drones. The base of the drone is installed in the installation hole 201, and the fixing bolts 202 are screwed to fix the drone. At the same time, the rotating wheel 16 can be rotated to make the adjusting shaft 1601 rotate and drive the movable block to move in the through groove 1501, so that the adjusting plate 1602 moves up and down and drives the fixing plate 17 to move up and down. The lower end surface of the fixing plate 17 abuts against the top of the drone, so as to further improve the firmness of the drone fixation. When the drone is landing, the roller installed on the lower end surface of the U-shaped support frame 7 abuts against the ground, so that the U-shaped support frame 7 flips over. When the U-shaped support frame 7 is flipped over to a certain angle, the sliding block 501 will slide on the outer edge surface of the sliding shaft 5. When the sliding block 501 slides, the first spring 502 will be deformed to provide a buffer, so as to provide a better buffering effect when the UAV lands. When the U-shaped support frame 7 is flipped over to a certain angle, the second spring 801 will be deformed by the pulling force of the buffer shaft 9, thereby further realizing the buffering effect. When the UAV lands, the abutment plate 1301 connected to the extension rod 13 squeezes the shock-absorbing spring 14, so that the shock-absorbing spring 14 is deformed to provide a buffer. At the same time, the supporting foot 1201 abuts against the ground to prevent rollover during landing, thereby providing anti-tilt protection. The UAV support frame for environmental monitoring has a reasonable structure, is easy to adapt to the installation requirements of different UAVs, and is easy to provide a certain degree of buffering when the UAV lands, while providing anti-tilt protection, and has strong practicality.
