Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a counterweight-stabilized photovoltaic panel mounting base. Background Technology

[0002] Photovoltaic power generation is an important component of renewable resource utilization. Photovoltaic power generation mainly uses solar panels facing the sun to convert solar energy into electrical energy. In order to reduce shading and stabilize power generation, solar panels need a support device to support them. Photovoltaic brackets are the support devices that support and fix solar panels, and the bottom of the photovoltaic brackets usually needs to use mounting bases to provide support.

[0003] Most existing photovoltaic panel mounting bases are fixed using cast-in-place concrete bases or anchored bases. However, in special geological conditions such as soft soil, sandy land, and rock layers, anchored bases are prone to slippage or cannot be drilled in, resulting in a sharp drop in stability. Furthermore, materials such as concrete and steel bars need to be transported on-site, and concrete requires a 28-day curing period, which prolongs the power station construction cycle and causes the optimal grid connection time to be missed. Therefore, this application proposes a counterweight-stabilized photovoltaic panel mounting base. Utility Model Content

[0004] The purpose of this invention is to provide a counterweight-stabilized photovoltaic panel mounting base, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a counterweight-stabilized photovoltaic panel mounting base, including a column base and a base support assembly disposed above the column base.

[0006] The base support assembly includes a grid-shaped support frame and several movable slots on the sides of the support frame. The support frame is fixed above the column base, and support columns are installed inside the support frame. A counterweight system is installed inside the movable slots. The column base is used to contact the ground or other locations where the photovoltaic panels are installed. The grid-shaped support frame not only improves the support effect, but the grooves on the sides of the grid also provide space for the installation of the counterweight system. The support columns are located inside the support frame for connection with the photovoltaic mounting frame. The counterweight system provides gravity to the mounting base, directly pressing the mounting base firmly.

[0007] The counterweight system includes a limiting screw, counterweights, and a locking nut. The limiting screw is vertically fixed to the column base. Several counterweights are arranged overlappingly on the limiting screw. The locking nut is connected to the limiting screw to lock the counterweights. By overlapping multiple counterweights on the limiting screw and finally screwing the locking nut onto the limiting screw, the multiple counterweights are pressed and fixed in place. The number of counterweights can be reduced or added as needed.

[0008] As a preferred embodiment of this invention, the column base has several mounting holes near its side. If anchoring is required during installation, expansion bolts can be used with these mounting holes for installation.

[0009] In a preferred embodiment of this invention, a fixing plate is connected to the top of the support frame. The fixing plate has positioning holes, and positioning bolts are installed in these holes. Several locking screw holes are provided on the side of the support column, and the positioning bolts are connected to the corresponding locking screw holes to fix the support column. The positioning bolts secure the support column. When the height of the support column needs to be adjusted, simply unscrew the positioning bolts from the locking screw holes, and then the support column can be moved in and out of the support frame. After adjusting to a certain height, the positioning bolts can be screwed back into the locking screw holes to re-fix the support column.

[0010] As a preferred embodiment of this invention, reinforcing ribs are provided between the plurality of movable slots. These reinforcing ribs enhance the stability and firmness of the supporting frame and the plurality of movable slots.

[0011] As a preferred embodiment of this invention, a mounting base is fixed above the support column. The mounting base is used to connect the photovoltaic panel mounting bracket.

[0012] In a preferred embodiment of this invention, the counterweight has a limiting hole, through which it is inserted into a limiting screw. A groove is provided on the side of the counterweight, and a handle is fixed within the groove. When installing the counterweight, it is inserted into the limiting screw using the limiting hole, facilitating fixation with a locking nut. The groove and handle primarily facilitate the removal of the counterweight.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention can meet the non-destructive installation requirements of temporary sites and fragile ground (such as roof waterproofing layers) by setting up a counterweight system, and the height adjustment function of the support column can adapt to the needs of photovoltaic panels with different tilt angles and different installation heights.

[0014] Compared to traditional rectangular frames, the "well"-shaped support frame has more even support points and stronger resistance to tipping and deformation. The reinforcing ribs between the movable slots further enhance the overall integrity of the frame, preventing the frame from cracking due to localized stress after the counterweight is installed. The counterweight system is rigidly fixed by limit screws and locking nuts, which can prevent the counterweight from shifting or falling off, ensuring long-term stability of the gravity stabilization effect. Even under the influence of external environments such as strong winds and vibrations, the base can still maintain overall stability. Attached Figure Description

[0020] Please see Figure 1-5 This utility model provides a technical solution: a counterweight stabilized photovoltaic panel mounting base, including a column base 1 and a base support component 2 disposed above the column base 1.

[0021] The base support assembly 2 includes a grid-shaped support frame 201 and several movable mounting slots 202 on the sides of the support frame 201. The support frame 201 is fixed above the column base 1. Support columns 203 are installed inside the support frame 201, and a counterweight system 3 is installed inside the movable mounting slots 202. The column base 1 is used to contact the ground or other locations where the photovoltaic panels are installed. The grid-shaped support frame 201 not only improves the support effect, but the grooves 3022 on the sides of the grid also provide space for the installation of the counterweight system 3. The support columns 203 are located inside the support frame 201 for connection with the photovoltaic mounting frame. The counterweight system 3 provides gravity to the mounting base, directly pressing the mounting base firmly.

[0022] The counterweight system 3 includes a limiting screw 301, counterweight blocks 302, and a locking nut 303. The limiting screw 301 is vertically fixed to the column base 1. Several counterweight blocks 302 are provided, and the counterweight blocks 302 are stacked on the limiting screw 301. The locking nut 303 is connected to the limiting screw 301 to lock the counterweight blocks 302. By stacking multiple counterweight blocks 302 on the limiting screw 301, and finally screwing the locking nut 303 onto the limiting screw 301, the multiple counterweight blocks 302 are pressed and fixed by the locking nut 303. The number of counterweight blocks 302 can be reduced or added as needed.

[0023] Furthermore, the column base 1 has several mounting holes 101 near its side. If anchoring is required during installation, expansion bolts can be used with the mounting holes 101 for installation.

[0024] Furthermore, a fixing plate 2011 is connected above the support frame 201. The fixing plate 2011 has positioning holes 2012, and positioning bolts 2013 are installed in the positioning holes 2012. Several locking screw holes 2031 are opened on the side of the support column 203. The positioning bolts 2013 are connected to the corresponding locking screw holes 2031 to fix the support column 203. The positioning bolts 2013 are used to fix the support column 203. When it is necessary to adjust the height of the support column 203, simply unscrew the positioning bolts 2013 from the locking screw holes 2031, and then operate the support column 203 to extend and retract within the support frame 201. After adjusting to a certain height, the positioning bolts 2013 can be screwed back into the locking screw holes 2031 to re-fix the support column 203.

[0025] Furthermore, reinforcing ribs 2021 are connected between the plurality of movable mounting slots 202. The reinforcing ribs 2021 are provided to improve the stability and firmness between the support frame 201 and the plurality of movable mounting slots 202.

[0026] Furthermore, a mounting base 2032 is fixed above the support column 203. The mounting base 2032 is used to connect the photovoltaic panel mounting bracket.

[0027] Furthermore, the counterweight 302 has a limiting hole 3021, through which it is inserted into the limiting screw 301. A groove 3022 is provided on the side of the counterweight 302, and a handle 3023 is fixed within the groove 3022. When installing the counterweight 302, it is inserted into the limiting screw 301 using the limiting hole 3021, facilitating fixation with a locking nut 303. The groove 3022 and handle 3023 primarily facilitate the removal of the counterweight 302.

[0028] In summary, this mounting base first uses the column base 1 as the contact base with the ground (or other mounting surface). The mounting holes 101 on its side can be fixed in two ways depending on the requirements: if stronger anchoring is required, ground anchoring can be achieved through the mounting holes 101 and expansion bolts; if no destructive fixing is required, it can be directly tightened by the gravity of the subsequent counterweight system 3. A "well"-shaped support frame 201 is fixed above the column base 1. The frame provides a stable support framework for the overall structure, and the movable mounting slots 202 on its side reserve installation space for the counterweight system 3. At the same time, the support column 203 inside the frame serves as the core component connecting the photovoltaic mounting frame, building a vertical support channel for the photovoltaic panels. The counterweight system 3 achieves pressure stabilization through a "limiting-overlapping-locking" process. The limiting screw 301 is vertically fixed on the column base 1, serving as the installation reference for the counterweight block 302. The counterweight blocks 302 with limiting holes 3021 are then fitted one by one onto the limiting screw 301 through the limiting holes 3021. The number of counterweight blocks 302 can be increased or decreased according to the load-bearing requirements of the installation scenario. Finally, the locking nut 303 is tightened to firmly press the overlapping counterweight blocks 302 onto the limiting screw 301. The gravity of the counterweight blocks 302 acts directly on the column base 1, tightly pressing the entire mounting base onto the mounting surface and preventing the base from shifting or shaking. When height adjustment is required, unscrew the positioning bolts 2013 in the positioning holes 2012 of the fixing plate 2011 to allow the support column 203 to freely extend and retract within the support frame 201. After adjusting to the height suitable for the photovoltaic panel installation angle, rescrew the positioning bolts 2013 into the corresponding locking bolt holes 2031 of the support column 203 to fix the position of the support column 203. The mounting base 2032 at the top of the support column 203 directly connects to the photovoltaic panel mounting bracket, completing the complete support link from the base to the photovoltaic panel. At the same time, the reinforcing ribs 2021 between the movable mounting slots 202 of the support frame 201 further strengthen the connection strength between the frame and the mounting slots, preventing structural deformation during long-term use.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
