[0022] In one embodiment, referring to Figure 1 , a fixing device for a photovoltaic support foundation cast-in-place pile of the present utility model includes an anchor pulling assembly, an adjusting assembly, and a positioning assembly.

[0023] Among them, the anchor pulling assembly includes an anchor tie rod 1 and a support rod 2 arranged on the anchor tie rod 1. The support rod 2 is provided with a coarse adjustment part and a fine adjustment part. The coarse adjustment part and the fine adjustment part rotate under the action of an external force to change the length of the support rod 2; the positioning assembly includes a positioning plate 3 hinged to the end of the support rod 2, and the positioning plate 3 is provided with a positioning arc groove 4; the adjusting assembly includes a first adjusting rod 5 and a second adjusting rod 6 respectively rotatably connected to the support rod 2 and the positioning plate 3, an adjusting sleeve 7 respectively rotatably connected to the first adjusting rod 5 and the second adjusting rod 6, and an adjusting column 8 movably arranged on the support rod 2. The adjusting column 8 is threadedly connected to the support rod 2 and the adjusting sleeve 7 respectively. The adjusting column 8 rotates under the action of an external force to make the adjusting sleeve 7 move towards or away from the support rod 2, thereby driving the positioning plate 3 to rotate relative to the support rod 2.

[0024] Furthermore, referring to Figure 4 , it further includes an anchor pulling plate 9. The center of the anchor pulling plate 9 is provided with an anchor pulling sleeve 10. One end of the anchor pulling sleeve 10 extends beyond the anchor pulling plate 9 to form a tip with a decreasing outer diameter; the anchor tie rod 1 is detachably installed in the anchor pulling sleeve 10.

[0025] Preferably, the anchor pulling sleeve 10 is a hollow cylindrical rod, and the anchor pulling plates 9 are located on both sides of the anchor pulling sleeve 10.

[0026] Preferably, the thickness of one end of the anchor pulling plate 9 close to the tip of the anchor pulling sleeve 10 is thinner.

[0027] In the above setting, the anchor tie rod 1 is inserted into the ground to connect the anchor tie rod 1 with the ground, providing support for the subsequent concrete foundation of the photovoltaic support; the anchor tie rod 1 can be inserted into the anchor sleeve 10, and the anchor sleeve 10 and the anchor plate 9 are inserted into the ground together. The contact area with the ground is increased through the anchor plate 9, thereby increasing the friction force and holding the stability of the connection between the anchor tie rod 1 and the ground.

[0028] Further, referring to Figure 3 , the support rod 2 includes a support main rod 201 and a support sub-rod 202 actively arranged inside the support main rod 201. A coarse adjustment part is formed between the support main rod 201 and the support sub-rod 202; a locking part 203 is provided on the support main rod 201, and the locking part 203 abuts against the support sub-rod 202 under the action of an external force, thereby fixing the relative position between the support main rod 201 and the support sub-rod 202.

[0029] Preferably, the support main rod 201 is a rectangular rod with a hollow interior, and through holes are arranged at intervals on the support main rod 201; the locking part 203 is a spring piece arranged on the support main rod 201, and a clamping head is provided on the spring piece. The clamping head is clamped with the through holes at different positions on the support main rod 201, thereby adjusting the positions between the support main rod 201 and the support sub-rod 202, and further adjusting the length of the support rod 2. The connection method between the support main rod 201 and the support sub-rod 202 can adopt an existing structure, and the rectangular support main rod 201 and support sub-rod 202 can limit the relative rotation between the two.

[0030] Further, referring to Figure 1 、 2 , the fine adjustment part includes a fine adjustment rod 11 arranged at the end of the support sub-rod 202. The fine adjustment rod 11 is connected to the support sub-rod 202 by threads; the first adjustment rod 5 is rotatably connected to the fine adjustment rod 11.

[0031] Preferably, an adjusting nut 12 is rotatably arranged at the end of the support sub-rod 202 away from the support main rod 201. External threads are provided on the outer wall of the fine adjustment rod 11, and the adjusting nut 12 is threadedly connected to the fine adjustment rod.

[0032] By rotating the adjusting nut 12, the relative position between the fine adjustment rod 11 and the support sub-rod 202 can be adjusted under the action of the threads. During the process of rotating the adjusting nut 12, hold the fine adjustment rod 11 with one hand to prevent the fine adjustment rod 11 from rotating accordingly.

[0033] Further, referring to Figure 1 , ear plates 13 are arranged at intervals on the positioning plate 3, and a rotating shaft 14 is provided on the ear plates 13; the fine adjustment rod 11 is rotatably connected to the rotating shaft 14.

[0034] Preferably, a rotating hole is provided on the fine adjustment rod 11, and the fine adjustment rod 11 is rotatably connected to the rotating shaft 14 through the rotating hole.

[0036] Further, referring to Figure 1 , the positioning plate 3, the fine-tuning rod 11, and the adjusting sleeve 7 are respectively provided with support plates 15 at intervals. The support plates 15 are provided with hinge shafts 16. The two ends of the first adjusting rod 5 and the second adjusting rod 6 are respectively rotatably connected to the hinge shafts 16; the second adjusting rod 6 is a telescopic rod.

[0037] Preferably, the fine-tuning rod 11 is provided with a threaded hole, and the adjusting column 8 is connected to the threaded hole by a thread. One end of the adjusting column 8 passing through the threaded hole is threadedly connected to the adjusting sleeve 7.

[0038] In the above setting, by rotating the adjusting column 8, under the action of the thread, the adjusting sleeve 7 is driven to move towards or away from the fine-tuning rod 11. During the process of the adjusting sleeve 7 moving towards the fine-tuning rod 11, the first adjusting rod 5 pushes the positioning plate 3 to rotate along the rotating shaft 14, and the angle between the positioning plate 3 and the first adjusting rod 5 gradually decreases, and the second adjusting rod 6 is stretched; during the process of the adjusting sleeve 7 moving away from the fine-tuning rod 11, the first adjusting rod 5 pushes the positioning plate 3 to rotate along the rotating shaft 14, and the angle between the positioning plate 3 and the first adjusting rod 5 gradually increases, and the second adjusting rod 6 is compressed; thus, the angle of the positioning plate 3 relative to the support rod 2 is adjusted.

[0039] In this embodiment, the anchor tie rod 1 is connected to the ground to provide stable support for the whole device, and by adjusting the length of the support rod 2, the position of the positioning plate 3 is adjusted. Combining with the adjustment of the adjusting column 8 to adjust the angle of the positioning plate 3, the positioning plate 3 is connected to the column 17 of the photovoltaic support. The positioning plate 3 is held on the formwork 18 around the concrete column. The positioning arc grooves 4 respectively hold the column 17 and the formwork 18, thereby supporting the concrete column and preventing the concrete column from deflecting during the solidification process.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
