[0023] It is worth noting that, referring to Figure 1 , the top of the front and rear ends of the base body 1 is installed with a limiting block 3, the surface of the limiting block 3 is provided with a circular groove, and a support rod body 301 is inserted into the circular groove, according to the actual distance between the plurality of base bodies 1, the operator needs to select the appropriate length of the support rod body 301, the length of the support rod body 301 should be slightly larger than the distance between the two base bodies 1, to ensure that it can be firmly inserted into the circular groove of the limiting block 3, and provide enough support force, the selected support rod body 301 is inserted into the circular groove of the limiting block 3 on the surface of the two base bodies 1 respectively, the support rod body 301 will be stably limited in the circular groove, after the insertion of the support rod body 301 is completed, the operator needs to install a threaded rod 302 in the threaded hole 305 on the surface of the support rod body 301, the threaded rod 302 and the support rod body 301 are connected through threads, and can be rotated up and down to adjust the position, by rotating the threaded rod 302, it can move up and down along the threaded hole 305 of the support rod body 301, the top of the threaded rod 302 is connected with the support plate body 303 through the bearing 304, therefore, with the up and down movement of the threaded rod 302, the support plate body 303 will also move up and down accordingly, when the support plate body 303 moves to the appropriate height, it can closely fit and support the photovoltaic support located in the area between the plurality of column bases, can provide additional support force for the photovoltaic support, thereby enhancing the overall stability and carrying capacity of the entire photovoltaic support system, solving the technical problem that the photovoltaic support is usually supported by a plurality of front column bases, but the area between these bases lacks support structure, resulting in the photovoltaic support being in a suspended state in this area, lacking sufficient stability, making the photovoltaic support prone to deformation when bearing external pressure or its own gravity, thereby affecting the stability and safety.

[0024] It is worth noting that, referring to Figure 1The threaded hole 305 is internally penetrated by a threaded rod 302, and the penetration position of the threaded rod 302 and the threaded hole 305 is threadedly connected.

[0025] It is worth mentioning that, referring to Figure 3 The threaded rod 302 is rotationally connected with a bearing 304 at the top, and the bearing 304 is installed with a support plate body 303 at the top.

[0026] In the front pillar base using a photovoltaic support, in the normal working state, two clamping plates 201 are fixed on both sides of the concave plate body 202, the clamping rods 210 on the clamping plates 201 are clamped into the clamping grooves 211 on the inner wall of the concave plate body 202, which ensures the stable installation of the concave plate body 202. At this time, the second fixing cylinder 208 is connected with the connecting plate body 207, and the connecting plate body 207 exerts a certain pre-tightening force on the spring 206 in the first fixing cylinder 205, so that the spring 206 is kept in a compressed state but does not deform excessively. When the concave plate body 202 needs to be replaced, the operator presses the two clamping plates 201 with his hands. This action, through the direct connection of the clamping plate 201 and the second fixing cylinder 208, makes the second fixing cylinder 208 move inward together with the clamping plate 201. With the movement of the second fixing cylinder 208, the connecting plate body 207 also moves, further pressing the spring 206 in the first fixing cylinder 205. The compression of the spring 206 releases the locking force of the clamping rod 210 on the clamping groove 211, so that the clamping rod 210 gradually slides out of the clamping groove 211 on the inner wall of the concave plate body 202. When the clamping rod 210 is completely separated from the clamping groove 211, the concave plate body 202 loses the fixation of the clamping plate 201. At this time, the concave plate body 202 can be directly taken out from the installation position, completing the removal process. When a new concave plate body 202 needs to be installed, the bottom position of the new concave plate body 202 is aligned and extended to the outside of the two clamping plates 201. At this time, the inner wall clamping groove 211 of the concave plate body 202 should be opposite to the position where the clamping rod 210 enters. After releasing the manual pressing of the clamping plate 201, the spring 206 in the first fixing cylinder 205 begins to gradually restore its original length, pushing the connecting plate body 207 and the second fixing cylinder 208 to move outward. This movement drives the clamping plate 201 to expand outward until the clamping rod 210 is aligned and clamped into the clamping groove 211 on the inner wall of the concave plate body 202. After the clamping rod 210 is successfully clamped into the clamping groove 211, due to the elasticity of the spring 206 and the cooperation between the clamping rod 210 and the clamping groove 211, the concave plate body 202 can be adjusted in angle through the sliding of the clamping rod 210 in the clamping groove 211. According to the actual distance between the plurality of base bodies 1, the operator needs to select the appropriate length of the support rod body 301, which should be slightly larger than the distance between the two base bodies 1 to ensure that it can be firmly inserted into the circular groove of the limiting block 3 and provide sufficient support. The selected support rod body 301 is inserted into the circular groove of the limiting block 3 on the surface of the two base bodies 1 respectively. The support rod body 301 will be stably limited in the circular groove. After the insertion of the support rod body 301 is completed, the operator needs to install the threaded rod 302 in the threaded hole 305 on the surface of the support rod body 301. The threaded rod 302 is connected with the support rod body 301 through threads and can be adjusted in position by rotating up and down. By rotating the threaded rod 302, it can move up and down along the threaded hole 305 of the support rod body 301. The top of the threaded rod 302 is connected with the support plate body 303 through the bearing 304,Therefore, with the up and down movement of the threaded rod 302, the support plate body 303 will also move up and down accordingly, when the support plate body 303 moves to the appropriate height, it can closely fit and support the photovoltaic support located in the area between the plurality of column bases, can provide additional support for the photovoltaic support, thereby enhancing the overall stability and carrying capacity of the entire photovoltaic support system.
