Description

Technical Field

[0001] The utility model relates to the technical field of aerial survey mark templates, in particular to an assembled aerial survey mark template. Background Art

[0002] Aerial survey ground marks are marks for laying out image control points on the ground during aerial photogrammetry. When conducting aerial photogrammetry, a number of image control marks need to be laid out on the ground to be used for aerial photo point puncture and error correction during later data processing. Publication No. CN210089690U discloses a modular assembled aerial survey image control point ground mark, including a template. A pair of first color areas and a pair of second color areas are provided on the template. The first color areas and the second color areas are arranged crosswise, and the first color and the second color are contrasting colors. The template is formed by splicing at least two template blocks. In actual application of the above technology, the connection between the two color blocks is simple. After the color blocks are assembled, the corners are easy to fall off and are not stable enough, which can easily cause aerial survey errors. Improvements are needed. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical scheme: an assembled aerial survey mark template, including a first color block and a second color block, the surface of the first color block is provided with a groove, the surface of the first color block is fixedly installed with an extension block, the surface of the first color block is provided with a screw hole, the surface of the first color block is provided with an angle sleeve, a bolt is threadedly connected between the screw hole and the angle sleeve, and a turning handle is fixedly installed on the surface of the bolt.

[0005] Preferably, the extension block is matched with the groove. Here, when the logo template is assembled, the extension block on the surface of the second color block is aligned with the groove of the first color block. When the extension block fits with the groove, the assembly of the first color block and the second color block can be completed. The extension block can fit the groove just right, so that the logo template will not be misplaced during use, increasing the stability of the logo template, and also can quickly find the installation position during installation, reducing the installation time.

[0006] Preferably, the shape of the turning handle is valve-shaped. Here, when the two first color blocks and the two second color blocks are combined, they can be fixed with a corner sleeve, which is placed at a corner of the first color block and the second color block. After the installation is completed, the corner sleeve is connected to the screw hole with a bolt. When the bolt is screwed into the screw hole, the valve-shaped turning handle can be easily screwed in, saving installation and combination time, and greatly improving the use efficiency of the aerial survey mark template.

[0007] Preferably, the number of the first color blocks and the second color blocks are both two, the two first color blocks are symmetrically distributed, and the two second color blocks are also symmetrically distributed. Here, the entire aerial survey sign template is composed of two first color blocks and two second color blocks, and the four color plates are cross-diagonally distributed. After assembly, the color blocks of the same color are diagonally symmetrically distributed, thereby realizing the function of the aerial survey sign.

[0008] Preferably, the number of the corner sleeves is four groups, and the four groups of corner sleeves are symmetrically distributed in pairs at the four corners of the color block. Here, after the four color plates are installed, the four groups of corner sleeves can be used to fix the color plates, and the corner sleeves can just fit with the same end corners of the first color block and the second color block, and then the corner sleeves are fixed with bolts, which can greatly improve the stability of the aerial survey sign template.

[0009] Preferably, a fixing block is fixedly installed on the bottom surface of the first color block, a rotating shaft is rotatably connected to the surface of the fixing block, and an anchor bolt is fixedly installed on the surface of the rotating shaft. Here, the environment in which the aerial survey is required is different, the anchor bolt is installed on the rotating shaft, the rotating shaft is rotated, and the anchor bolt is inserted into the soil, which can increase the stability of the aerial survey sign template when it is placed. When it is on a flat ground, the anchor bolt can be rotated and placed horizontally, thereby improving the environmental applicability of the aerial survey sign template.

[0010] Preferably, a non-slip pad is fixedly mounted on the surface of the fixed block. Here, when the aerial survey mark template is placed on a flat ground, the non-slip pad at the bottom of the fixed block can increase the friction between the template and the ground to prevent the aerial survey mark template from moving due to weather influences, resulting in inaccurate aerial survey data.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, by setting the first color block, the second color block, the extension block, the groove, the screw hole, the corner sleeve, and the bolt structure, the extension block can fit the groove exactly, so that the sign template will not be misplaced during use, thereby increasing the stability of the sign template. Four sets of corner sleeves are used to fix the color plate, and the corner sleeve can fit the same end corner of the first color block and the second color block, and then the corner sleeve is fixed with bolts, which effectively avoids the problem of easy falling off of the corners of the aerial survey sign template, greatly increases the stability of the template, and thus increases the stability of the aerial survey.

[0013] 2. In the utility model, by setting a turning handle, a fixed block, a rotating shaft, and an anchor bolt structure, the valve-shaped turning handle can be convenient for personnel to screw in, saving installation and assembly time, and greatly improving the use efficiency of the aerial survey sign template. The aerial survey environment is different. The rotating shaft is installed with the anchor bolt, and the rotating shaft is rotated to insert the anchor bolt into the soil, which can increase the stability of the aerial survey sign template when placed. When on a flat ground, the anchor bolt can be rotated and placed horizontally to improve the environmental applicability of the aerial survey sign template. When placing the aerial survey sign template on a flat ground, the anti-slip pad at the bottom of the fixed block can increase the friction between the template and the ground to prevent the aerial survey sign template from moving due to weather influences, resulting in inaccurate aerial survey data.
