Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and in particular to a leveling device for installing a double-column photovoltaic bracket. Background Art

[0002] The double-column photovoltaic bracket uses two columns to fix the photovoltaic modules. By adjusting the height and angle of the columns, the photovoltaic modules can receive solar radiation at the optimal angle to improve the photoelectric conversion efficiency. Photovoltaic brackets are usually installed on mountain slopes. During the installation of the double-column photovoltaic bracket, it is necessary to ensure the verticality of the two sets of columns and the centration between the two sets of columns, so as to ensure that the photovoltaic panels are located on the same plane after installation.

[0003] During the common installation of double-column photovoltaic brackets, after the foundation of the photovoltaic bracket is poured on the ground, the columns are usually connected and fixed with embedded bolts. However, during the installation process, since the two groups of columns are installed separately, if there is a position deviation in one group of columns when connected with the embedded bolts, it will inevitably cause deviation from the other group of columns. That is, the centers of the two groups of columns are difficult to be located on the same plane, affecting the concentricity between the two groups of columns; at the same time, it is difficult to ensure the verticality of the columns during the installation process.

[0026] Preferably, a locking hole is provided on the supporting main rod 101, and the locking member 103 comprises a locking stud, which is installed in the locking hole through a thread.

[0027] For further information, see Figure 1 A support plate 10 is provided on the end of the supporting main rod 101 and the supporting auxiliary rod 102, and screw holes 11 are provided on the supporting plate 10 at intervals; the leveling rod 4 is installed in the screw hole 11 through threads.

[0028] Preferably, adjustment plates 12 are provided on both sides of the bottom end of the support plate 10 , and the screw holes 11 are located on the adjustment plates 12 .

[0029] Preferably, a supporting base plate 13 is provided on the end of the leveling rod 4 .

[0030] In the above-mentioned setting, the position of the supporting sub-rod 102 in the supporting main rod 101 is moved to adjust the length of the supporting rod 1, and the locking column is moved downward under the action of the thread to abut against the supporting sub-rod 102, thereby fixing the position between the supporting sub-rod 102 and the supporting main rod 101. By adjusting the length of the supporting rod 1, it is convenient to overlap the supporting main rod 101 and the supporting sub-rod 102 on the concrete foundation of the two groups of columns respectively; the supporting base plate 13 on the leveling rod 4 abuts against the concrete foundation of the two groups of columns respectively, and the adjusting plate 12 is driven to move up or down by rotating the leveling rod 4 under the action of the thread, so that the two sides of the axis of the supporting main rod 101 or the supporting sub-rod 102 move up or down, and the level bubble 3 is used to provide a reference, so as to adjust the horizontality of the supporting main rod 101 and the supporting sub-rod 102, thereby ensuring that the first infrared emitting unit 8 and the second infrared emitting unit 9 are located on the same horizontal plane.

[0031] For further information, see Figure 3 The center tangent of the base 5 in the vertical direction coincides with the center tangent of the supporting main rod 101 in the vertical direction; the adjusting member 6 includes an adjusting screw 14, a light rod portion 15 is provided in the middle of the adjusting screw 14, and the adjusting screw 14 is rotatably connected to the base 5 through the light rod portion 15.

[0032] Preferably, the base 5 is a block structure, a through hole 16 is provided on the base 5, a bearing is provided in the through hole 16, and the smooth rod portion 15 of the adjusting screw 14 is fixedly connected to the inner ring of the bearing.

[0033] For further information, see Figure 1 \2, slide grooves 17 are symmetrically arranged on both sides of the base 5; the sliding sleeves 7 are slidably installed in the slide grooves 17, and the sliding sleeves 7 on both sides of the base 5 are threadedly connected with the adjusting screw 14 through positive thread and negative thread respectively.

[0034] Preferably, the slide groove 17 is formed as a rectangular body with one end open and a concave middle portion; both ends of the adjusting screw rod 14 are rotatably connected to the side ends of the slide groove 17 .

[0035] Preferably, the sliding sleeve 7 is a block structure, and a hole 18 is provided on the sliding sleeve 7, and a thread is provided in the hole 18.

[0036] In the above arrangement, the two groups of sliding sleeves 7 are driven to move in the sliding groove 17 by rotating the adjusting screw 14 under the action of the thread. Since the sliding groove 17 limits the sliding sleeve 7, the sliding sleeve 7 can only move but cannot rotate with the adjusting screw 14. In the process of the sliding sleeve 7 moving toward or in the opposite direction, the two groups of second infrared emitting parts 9 are driven to move toward or in the opposite direction.

[0037] In this embodiment, the length of the support rod 1 is adjusted by adjusting the positions of the main support rod 101 and the auxiliary support rod 102, and the length of the support rod 1 is fixed by the locking member 103, so that the main support rod 101 and the auxiliary support rod 102 can be overlapped on the concrete foundation of the two groups of columns; and the support rod 1 is pushed to flip horizontally along its axis by rotating the leveling rod 4, so that the left and right sides of the support rod 1 are located in the same horizontal plane, and the position of the leveling rod 4 is determined by the leveling bubble 3, thereby ensuring that the first infrared emitting part 8 and the second infrared emitting part are located in the same horizontal plane; when installing the photovoltaic bracket When erecting a column, the vertical ray emitted by the first infrared emitting unit 8 is used to align (coincide) with the center line of the column, and the vertical ray emitted by the second infrared emitting unit 9 is used to fit with the two sides of the column. By having two groups of second infrared emitting units 9 fit with the two side edges of the column, the verticality of a single column can be ensured during installation, and the center line of the column can be determined. When two groups of columns are installed, the installation positions of the two groups of columns can be determined based on the rays emitted by the first infrared emitting unit 8 and the second infrared emitting unit 9. While ensuring the verticality of the two groups of columns, it is ensured that the center lines of the two groups of columns are located on the same horizontal plane, thereby ensuring the installation accuracy.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
