[0028] At present, the positioning of courtyard steel piles is complicated and has large errors, which affects the construction and increases the difficulty of construction. Figures 1 to 5 As shown, an embodiment of the present invention provides a photovoltaic support steel pile positioning device for solving the above problems, which includes: A fixed disc seat 5, wherein the fixed disc seat 5 is provided with a fulcrum shaft, and the fixed disc seat can rotate around the fulcrum shaft; The telescopic connecting rod is provided with two telescopic connecting rods, wherein a movable sleeve 3 is provided at the first end of the telescopic connecting rod and a positioning sleeve 4 is provided at the second end, wherein the movable sleeve 3 is connected to the fulcrum rotating shaft, and a corresponding angle is set between the two telescopic connecting rods; The positioning member 6 is provided with a plurality of positioning members 6, the number of which is at least equal to or greater than the number of positioning points. The positioning member 6 passes through the movable sleeve 3 and is nailed into the ground reference point. The positioning member 6 passes through the positioning sleeve 4 and is nailed into the ground to obtain a basic positioning point.

[0029] The fixed disc seat can be made of steel, and the positioning piece can be a positioning steel chisel, and a large number of positioning steel chisels are prepared in advance. In addition, the fulcrum shaft can be a steel casing, and the movable casings on the two telescopic connecting rods are connected to the fulcrum shaft in layers up and down without affecting each other. The positioning steel chisel can pass through the steel casing and nailed into the ground reference point.

[0030] Specifically, the telescopic connecting rod includes a telescopic outer rod 1 and a telescopic inner rod 2. The telescopic inner rod 2 is telescoped inside the telescopic outer rod 1 to adjust the length of the telescopic connecting rod to correspond to the size of the placement point, that is, the distance between the two positioning points.

[0031] Preferably, the telescopic inner rod 2 and the telescopic outer rod 1 are made of steel pipes. The outer wall of the telescopic inner rod has a size scale, and the telescopic length of the telescopic inner rod is measured by the size scale to determine the length of the telescopic connecting rod after adjustment. After the adjustment is completed, the telescopic inner rod 2 is fixed to the telescopic outer rod 1 by fixing the top screw 7 (i.e., the set screw).

[0032] Specifically, the fixed disc seat 5 is provided with an arc-shaped edge with the fulcrum shaft as the center of the circle and two straight edges respectively connected to the two ends of the arc-shaped edge and perpendicular to each other. The two straight edges and the arc-shaped edge enclose a disc surface, and the fulcrum shaft is arranged at the junction of the two straight edges. The telescopic connecting rod is fixed to the fixed disc seat 5 by a fixing bolt 8. The fixed disc seat is provided with a fixing hole (which can be a threaded hole). The fixing bolt is fixed through the fixing hole and fixes the telescopic connecting rod to the fixed disc seat. The upper side of the straight edge is provided with a limiting edge 9 that cooperates with the telescopic connecting rod. Because the commonly used angle is 90 degrees, the two-rod telescopic connecting rod can be quickly fixed by limiting the limiting edge and cooperating with the fixing bolt.

[0033] Furthermore, the fixed disc seat 5 is provided with an angle scale for measuring the expansion angle of the two telescopic links, that is, the angle scale is provided along the arc edge of the upper surface of the fixed disc seat 5. In this way, after determining the pay-off angle, one of the telescopic links is fixed to the fixed disc seat 5 by the fixing bolt 8, and this step is repeated to fix the other telescopic link to the fixed disc seat 5.

[0034] In the above technical solution, the photovoltaic bracket steel pile positioning device is a modular structure, consisting of a fixed disc seat, a telescopic connecting rod and a positioning piece. The fixed disc seat and the telescopic connecting rod can be pre-assembled together or temporarily assembled on site for easy carrying and on-site construction use. In addition, they can all be made of conventional materials, which is easy to manufacture and has low processing costs.

[0035] It is understandable that the device is assembled by determining the point spacing according to the foundation point drawing. The positioning steel chisel in the portable courtyard steel pile positioning device can be equipped with a corresponding length according to the flatness of the on-site ground. The telescopic outer tube and the telescopic inner tube can be equipped with a corresponding length according to the foundation spacing to meet the on-site point placement work.

[0036] Specific implementation: refer to Figures 1 to 5 After the reference point is determined on site, the movable sleeve 3 on the fixed plate seat 5 is placed so that it coincides with the reference point. The positioning member 6 is nailed into the ground reference point through the movable sleeve 3. The device is rotated so that one of the telescopic connecting rods coincides with the reference line. The positioning sleeve 4 at the free end of the telescopic inner rod is the preset basic point. The positioning member 6 is nailed into the ground through the positioning sleeve 4 to obtain the basic positioning point.

[0037] Remove the device, and insert the movable sleeve 3 into the positioning piece 6 corresponding to the previous basic positioning point to obtain a new basic positioning point; Repeat the above steps to complete the on-site point layout and proceed to the next step of piling.

[0038] Since the basic positioning points of the photovoltaic bracket are usually distributed in a rectangular array, the two telescopic links can be in a vertical relationship. The fixed plate seat together with the two telescopic links can locate two basic positioning points each time they are positioned. The telescopic links are set to a fixed length according to the positioning size, which is not only accurate in positioning, but also highly efficient. In addition, the two telescopic links can adjust the length according to the spacing between the two basic positioning points, which is suitable for different positioning data and has universality.

[0039] Therefore, the present invention improves the construction steps through the use of the steel pile positioning device, eliminates the need for measuring and laying out lines, reduces positioning errors, reduces construction difficulty, enables a single person to complete the steel pile positioning work, and reduces construction costs.
