Description

Technical Field

[0001] The invention belongs to the field of detection technology, and in particular relates to a measuring device with a ruler having a buffer support. Background Art

[0002] The application technology of drones has become increasingly mature, and institutions engaged in drone research and development have gathered the world's best talents, but the actual application of drones in the surveying field has not seen a significant increase. The reason is that there are too few technicians who are familiar with both surveying and drones.

[0003] Measuring drones are a rigid demand in many industries. Throughout the world, drone or mobile phone manufacturers have placed great hopes on the expansion of measurement technology on drones or mobile phones, and have made many attempts. However, they cannot be applied because the measurement scale and accuracy cannot meet the regulatory requirements of various industries.

[0004] For example, the Ministry of Transport or the Ministry of Housing and Urban-Rural Development requires a measurement accuracy of 0.01mm, and it can only be measured with a ruler, not an estimate. According to this requirement, it is currently impossible to measure with unmanned equipment. Because the flight or hovering of a drone relies on the forward and reverse rotation of the rotor to stir the air to obtain the corresponding power to support the realization of each action, and when the drone wants to hover and perform zero-distance measurement, the limited space will cause the drone to shake when hovering. At this time, when the ruler is in contact with the surface to be measured, the ruler will also shake, resulting in inaccurate measurement, and due to the reaction force of the ruler, it is easy to make the drone lose balance and cause the drone to crash. Therefore, how to make the drone's jitter when hovering not affect the measurement accuracy and ensure that the drone is not damaged during the measurement process is a difficult problem that technicians in this field have been thinking about. Summary of the invention

[0005] The purpose of the present invention is to provide a measuring device with a scale having a buffer support, so as to solve the technical problems in the above-mentioned prior art that the jitter of the unmanned detection equipment during hovering affects the measurement accuracy, and the drone is easily damaged during the measurement process.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figure 1-3As shown, a measuring device with a scale having a buffer support is installed on a drone for measuring surface defects when the drone is hovering, comprising: a camera body 1, the camera body 1 being connected to an inorganic device, the camera body 1 having a lens 2, a buffered telescopic scale 3 being provided on the outside of the lens 2, the buffered telescopic scale 3 having a scale body 33, a flexible support column 32 being connected to the circumferential outside of the plane where the scale body 33 is located, the flexible support column 32 together with the scale body 33 being retractable into a base 31, the base 31 being connected to the camera body 1 housing and / or the side wall of the lens 2, the flexible support column 32 being extended so that the scale body 33 is located directly above the lens 2, and the scale body 33 is in contact with the surface of the part to be measured when the drone is hovering for measurement, wherein the camera body 1 may be oriented at the top or bottom of the drone, or may be measured in the side direction by means of a mounting bracket, as long as the flexible support column 32 is in contact with the surface to be measured, the shaking of the drone hovering may be avoided to affect the measurement.

[0024] In a preferred embodiment of the present invention, the connection between the flexible support column 32 and the scale body 33 is a door frame and door panel connection structure, and the length of the scale body 33 is smaller than the length of the flexible support column 32. Such a structure is due to the small effective measuring surface of the scale body 33, and the flexible support column 32 has to bear the supporting and buffering functions, so that the height of the scale body 33 is slightly higher than the surface of the lens 2, and the width of the scale body 33 is sufficient to cover the effective working area of ​​the lens 2.

[0025] In a preferred embodiment of the present invention, the plane where the flexible support columns 32 on both sides of the ruler body 33 are located has a bent structure in the middle, so that when the flexible support columns 32 are extended, the upper part of the flexible support columns 32 is parallel to the top surface of the lens 2. When viewed from the side, the flexible support columns 32 have a 7-shaped bent structure, that is, after extension, they reach from the side position of the lens 2 to the top of the lens 2, thereby realizing that only a rough observation of the lens 2 is required during the drone inspection. When a situation requiring precise measurement is found during the rough observation, the flexible support columns 32 are extended to deliver the ruler body 33 to the upper part of the lens 2.

[0026] In a preferred embodiment of the present invention, the flexible support column 32 is connected to an air blowing or water filling device 34, and the air blowing or water filling device 34 is used to stretch the flexible support column 32, and the cushioning effect of the air also achieves a vibration reduction effect.

[0027] In a preferred embodiment of the present invention, a pull rope or elastic rope 36 is provided in the flexible support column 32 on one side or both sides of the ruler body 33, one end of the pull rope or elastic rope 36 is connected to the ruler body 33, and the pull rope or elastic rope 36 is connected to the pull rope retracting device 35. Figure 3For the sake of ease of expression, only the pull rope or elastic rope 36 on one side is drawn, but it can certainly be provided on both sides, and the pull rope 36 or elastic rope can be completely covered by the flexible support column 32, or can pass through the flexible support column 32. When passing through the flexible support column 32, a sealing structure is provided at the passing portion to prevent air leakage during the pulling process of the pull rope or 36, or the air leakage is very small.

[0028] In a preferred embodiment of the present invention, the flexible support column 32 is a rubber tube or bellows structure. As long as the structure of the flexible support column 32 can stretch when the blowing or water filling device 34 is working, it can shrink when it stops working or works in reverse to achieve the recycling effect.

[0029] In a preferred embodiment of the present invention, the pull cord retracting device 35 is an electric roller, and of course it can also be other retracting structures, as long as the line is released when the flexible support column 32 is extended, and the line is retracted when the flexible support column 32 needs to be retracted.

[0030] In a preferred embodiment of the present invention, the actions of the rope retracting device 35, the blowing or water filling device 34, the camera body 1 and the drone are controlled by a controller, so that preliminary observation and precise measurement can be automatically switched, and the measurement data can be saved and transmitted.

[0031] In a preferred embodiment of the present invention, the base 31 is a box-shaped structure with an open top, so that the flexible support column 32 has a storage space to prevent the flexible support column 32 from being affected by the outside world and becoming messy when not in use.

[0032] In a preferred embodiment of the present invention, not shown in the figure, a cover plate is arranged on the top of the base 31, and a hinge axis is provided in the middle part of the length direction of the cover plate and is hinged to the two sides of the length direction of the base 31, so that when the flexible support column 32 is extended, the cover plate is lifted up from one side to flip over, and when the flexible support column 32 is contracted, the cover plate can also be flipped downward, thereby achieving a dust-proof effect without affecting the free extension and retraction of the flexible support column 32.

[0033] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
