DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0029] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0031] In the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0032] The application of PHC piles as photovoltaic supports in brine pools has brought a series of new anti-corrosion challenges. The environment of brine pools is mainly corrosive elements such as chloride ions and sulfate ions, which are particularly unfavorable to alkaline concrete structures. The erosion of acidic water not only quickly reduces the physical properties of concrete, but also accelerates the corrosion process of internal steel bars, thus seriously threatening the overall durability of the concrete structure.

[0033] For the anti-corrosion measures of PHC pipe piles in brine environment, the method of applying anti-corrosion coating on the surface of PHC pipe piles is adopted. For the research on the protective performance of anti-corrosion coating, it is necessary to conduct thickness change test and measure the thickness change of coating at regular intervals. This requires marking the measuring points on the surface of PHC pipe piles coated with anti-corrosion coating. Since PHC pipe piles are cylinders, cylinders are curved surfaces. Unlike planes, the drawing of lines on curved surfaces needs to consider factors such as curvature and deformation. How to accurately draw axial lines parallel to the center line of the shaft and radial lines perpendicular to the center line of the shaft in space on the curved surface to ensure the continuity and smoothness of the lines is a technical challenge.

[0034] At present, there are several common methods for drawing lines on the surface of a cylinder. One is to directly use a ruler and pencil to mark the starting point and end point of the straight line on the surface of the cylinder along the axial direction and connect them with a ruler. Since the surface of the cylinder is a curved surface, this may cause the straight line drawn on the surface of the cylinder to be curved and inconvenient to operate. At the same time, this method cannot achieve radial line drawing; the second is to achieve axial and radial line drawing on a lathe, but it is not suitable for operation at the test site. At the same time, the cylinder is a curved surface, and it is inconvenient to use cutting equipment such as a toothless saw to directly cut the drawn axial and radial lines, and the continuity and smoothness of the lines cannot be guaranteed.

[0035] Based on the problems existing in the existing technology, such as Figure 1 As shown, this embodiment provides a sample measuring point marking device for drawing axial lines (straight lines) and radial lines (arcs) on the surface of a PHC pile within a preset diameter range, comprising a base 1, a support platform 2 rotatably connected to the base, a first vertical rod 3 connected to the base 1, and a second vertical rod 4 connected to the support platform 2; a slider 5 capable of sliding along the first vertical rod 3 is provided on the first vertical rod 3, and a marking pen 6 is provided on the slider 5.

[0036] In a specific implementation, a scale 7 is provided on the first vertical rod 3; an angle ruler 8 is provided at one end of the second vertical rod 4, and the angle ruler 8 is a disc-shaped structure. A slideway is provided on the first vertical rod 3, and the second vertical rod 4 is provided with a telescopic rod. A small angle grinder 11 can also be provided on the slider 5.

[0037] In a specific implementation, the first vertical rod 3 is located at one side of the base 1. The second vertical rod 4 is located at one side of the support platform 2, and the first vertical rod 3 and the second vertical rod 4 are arranged in parallel.

[0038] like Figure 2 As shown, the marking device described in this embodiment is made of steel material with greater rigidity. A circular groove of a preset size (in this embodiment, a diameter of 75 mm and a depth of 20 mm) is provided at the center of the base 1 for accommodating the bearing 14. A first vertical rod 3 with a height of 110 mm is welded to the side of the base 1 so that the first vertical rod 3 is fixed on the base 1 and remains vertical. The first vertical rod 3 has a first slideway 13 along the height direction, as shown in FIG. Figure 3 As shown, the first slideway 13 is used to place the slider 5, and the slider 5 can slide in the slideway along the vertical direction. There is a hole in the middle of the slider to place a pen and a small angle grinder. Figure 4 shown.

[0039] like Figure 5 As shown, the bottom of the support platform 2 has a circular protrusion, and the bearing 14 is sleeved on the protrusion and placed together on the lower base to ensure that the support platform can rotate. The second vertical rod 4 is welded to the side of the support platform 2, so that the second vertical rod 4 is fixed on the support platform and remains vertical. The second vertical rod 4 has a second slideway 15 along the height direction for placing the inner rod 9. The inner rod 9 can slide along the second slideway 15 in the height direction. At the same time, the second vertical rod 4 has a fixing bolt 10 for fixing the position of the inner rod 9, as shown in FIG. Figure 6 The upper part of the inner rod 9 is connected to the angle ruler 8, and the angle ruler is specifically as follows Figure 7 shown.

[0040] For ease of understanding, the following describes the method for using the device described in this embodiment in combination with practical applications:

[0041] First, mark the center of the upper surface of the cylindrical sample with a marker, place the cylinder on the support platform 2, adjust the height of the inner rod 9 so that the hole in the center of the angle ruler 8 coincides with the center of the marked cylindrical sample, and fix the position of the inner rod 9 with the fixing bolt 10.

[0042] Secondly, pass the marking pen 6 through the hole in the center of the slider 5, fix the position of the marking pen 6 as needed, put the slider 5 into the first slideway 13 of the first vertical rod 1, and move the slider 5 according to the scale to draw an axial line on the surface of the cylinder; pass the small angle grinder 11 through the hole in the center of the slider 5, fix the position of the small angle grinder 11 as needed, put the slider 5 into the first slideway 13, and move the slider 5 according to the scale to cut an axial seam on the surface of the cylinder.

[0043] Since there is a bearing 14 between the base 1 and the support platform 2, the support platform 2 can rotate around the central axis of the base 1 and drive the cylindrical sample to rotate, and the radial line or seam can be drawn or cut by comparing the angle ruler 8.

[0044] The sample measuring point marking device provided by the above embodiment can be realized and has broad application prospects.

[0045] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
