Description

Technical Field

[0001] The utility model belongs to an unmanned aerial vehicle (UAV) - launched self - vertical measuring scale. Background Art

[0002] The topographic surveying and mapping at the construction site is extremely important for the construction of urban subways, buildings, mountain roads, etc. Especially, the surveying and mapping under complex field conditions is extremely important for monitoring the construction quality and preventing geological disasters from damaging the construction site. The measuring scale is usually required to be set perpendicular to the horizontal plane at the measuring point. For complex field areas such as mountains, swamp uninhabited areas, and other wild complex areas where people cannot reach, it is very difficult and dangerous to arrange the measuring scale. Therefore, UAVs have been used to launch the measuring scale, that is, the UAV first determines each measuring point in the wild complex area, and then the UAV flies over each measuring point to launch the measuring scale, and the bottom of the measuring scale pierces into the ground. Although this UAV - launched measuring scale solves the problems of the inability of people to reach complex areas to set up measuring scales and the slow speed of setting up scales, the launched measuring scale cannot meet the requirement of being perpendicular to the horizontal plane at the measuring point, and the verticality rate of the launched measuring scale is less than 10%, resulting in inaccurate positioning and poor accuracy in measurement. Summary of the Invention

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model. The construction methods in the following embodiments are all conventional methods unless otherwise specified. The materials, devices, equipment, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0020] As Figures 1 to 4 shown, a self - hanging measuring scale for UAV delivery consists of a scale rod 2. A grounding tip 10 is provided at the bottom end of a fixed rod 7. A limiting disk 8 is provided between the upper end of the grounding tip and the lower end of the fixed rod. The diameter of the limiting disk is larger than that of the fixed rod. The function of the limiting disk is to prevent the lower end of the fixed rod from being inserted into the ground 12. The fixed rod is a metal tube, such as an aluminum tube. The grounding tip is made of steel. The weight of the grounding tip and the limiting disk is greater than the weight of the metal tube, so that after the UAV delivers it, the lower end of the fixed rod remains downward and the grounding tip is inserted into the ground 12. The upper end of the grounding tip 10 is fixedly connected to the middle part of the lower end of the limiting disk 8 by welding. The middle part of the upper end of the limiting disk is fixedly connected to the lower end of a screw rod 14. An internal thread through - hole is provided at the lower end of the fixed rod. The grounding tip and the limiting disk are screwed to the lower end of the fixed rod through the screw rod screwed into the internal thread through - hole. A counterweight 13 can be sleeved at the lower end of the fixed rod. The counterweight is a frustum with a through - hole in the middle for the fixed rod to pass through, made of cast iron, and each weighs 1 Kg, which is used to increase the weight of the lower end of the fixed rod to ensure that the grounding tip has enough weight to be inserted into the ground 12, so as to fix and support the fixed rod.

[0021] As Figure 2 shown, the upper end of the fixed rod 7 is axially connected to the lower part of a ball rod 5 through a bearing 6. The ball rod is obliquely arranged. The included angle between the axis line of the fixed rod and the axis line of the ball rod is 35 0 ~45 0。The top of the cue 5 is provided with a cue tip 4. On one side of the upper part of the scale rod 2, there is a shaft bowl 11 axially connected to the cue tip. The fixed rod 7 is axially arranged in the shaft bowl through the cue tip at the top of the cue and axially connected to the scale rod. Obviously, the cue tip and the shaft bowl serve as the fulcrums for the scale rod to be suspended. The lower end of the scale rod should be located above the upper end of the limit disc 8. The lower end of the scale rod is provided with a scale rod counterweight 9, so that the center of gravity of the scale rod is at the lower end. The scale rod counterweight and the counterweight are made of iron blocks. The upper end of the scale rod is provided with a collar 1 for the drone suspension to hoist. The scale rod is made of luminous plastic, which can be self-luminous plastic or stimulated luminescent plastic. They can emit fluorescence for a certain period of time after being stimulated (such as sunlight), which is beneficial for night illumination and measurement. Scale lines 3 and numbers for elevation are provided on the outer wall of the scale rod, which is beneficial for measurement.

[0022] During use, the drone suspension hoists the collar at the upper end of the scale rod, and carries the present utility model to fly to a height of 10 - 15 m above the ground where the measurement punctuation is laid out, and then drops the present utility model. The present utility model utilizes gravity, and the ground-piercing tip pierces into the ground 12 to fix and support the fixed rod. Whether the fixed rod is perpendicular to the horizontal plane when it pierces and is fixed on the ground or not, the scale rod is suspended on the inclined lower end side of the fixed rod through the cue tip and the shaft bowl. That is, under the action of the bearing 6, the cue always swings and hangs towards the inclined lower end side of the fixed rod (the angle between the fixed rod and the ground), and under the action of the scale rod counterweight and the cue tip and the shaft bowl at the lower end of the scale rod, the scale rod always stands perpendicular to the horizontal plane; that is, the ball bowl of the scale rod can rotate arbitrarily around the cue tip of the fixed rod. Under the action of the scale rod counterweight, the scale rod always stands perpendicular to the horizontal plane, so as to ensure that the placed measurement scale can meet the requirement of being set perpendicular to the horizontal plane at the measurement point.

[0023] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
