Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to a flexible photovoltaic support for soft soil that prevents tilting. Background Technology

[0002] Flexible photovoltaic (PV) support structures are large-span PV panel installation structures composed of foundation piles, steel wire ropes, and pre-tensioning components. They have the advantages of simple structure and convenient installation. Especially in some mountainous and ravine areas where foundation pile construction is difficult, flexible PV support structures can significantly reduce the number of foundation piles and improve installation efficiency.

[0003] Compared to traditional support structures, flexible photovoltaic supports have a greater single pile bearing capacity, making them prone to tilting and collapse, especially in areas with soft soil. Therefore, this invention provides a flexible photovoltaic support for soft soil that is designed to prevent tilting. Summary of the Invention

[0032] refer to Figures 1 to 5 A flexible photovoltaic support for soft soil to prevent tilting includes: a main base 1, a support component 4, a secondary base 2, a channel steel component 3, and a tie rod 5.

[0033] Among them, the bottom end of the support component 4 is fixedly installed on the top of the main base 1. The main base 1 is stably built in the geological layer to ensure the stability of the bottom end of the support component 4. There are two secondary bases 2, which are distributed parallel and equidistantly on both sides of the main base 1. The middle part of the channel steel component 3 is fixedly installed on the side of the main base 1, and the two ends of the channel steel component 3 are respectively located above the two secondary bases 2.

[0034] In this structure, the main base 1 and the secondary base 2 are connected as a whole by the channel steel component 3 to bear the force. When the main base 1 tilts, the channel steel component 3 transmits the force to the secondary base 2, thereby stabilizing the main base 1 by relying on the support of the secondary base 2 and preventing the main base 1 from tilting. Furthermore, the main base and the secondary base are separated, thereby preventing the soft soil from affecting the main base and the secondary base at the same time.

[0035] The first end of the tie rod 5 is fixedly installed with the support member 4, and the second end of the tie rod 5 is fixedly installed with the end of the channel steel member 3. The tie rod 5 is used to reinforce the integrity of the support member 4 and the channel steel member 3 and prevent the support member 4 from tilting.

[0036] In one embodiment, the main base 1 includes a first concrete base 101, which is generally elongated and wider at the top than at the bottom.

[0037] The top of the first concrete base 101 is provided with a shoulder 102. There are two shoulders 102 along the length of the first concrete base 101. The top of the first concrete base 101 at the non-shoulder position forms a protrusion 104. The bottom end of the support member 4 is installed on the top of the protrusion 104. The middle section of the channel steel member 3 is fixedly installed on the inner side of the shoulder 102.

[0038] Specifically, a prefabricated vertical screw 103 is provided on the top of the first concrete base 101. The bottom of the vertical screw 103 is embedded in the first concrete base 101 for more than 2 / 3 of its length. The vertical screw 103 passes through the base 401 at the bottom of the support member 4 and is threaded with a second nut.

[0039] A prefabricated transverse screw 105 is provided on the side of the protrusion 104 and above the shoulder 102. The transverse screw 105 passes through the protrusion 104 and extends out at both ends. The two ends of the transverse screw 105 are located in the two shoulders 102. The transverse screw 105 passes through the channel steel part 3 and is threadedly connected to the first nut 106.

[0040] In one embodiment, the support member 4 includes: a main rod 402, a base 401 fixedly connected to the bottom end of the main rod 402, a reinforcing member 404 fixedly connected between the side of the main rod 402 and the base 401 to increase the connection strength between the side of the main rod 402 and the base 401, and a connecting rod 403 fixedly installed on the top of the main rod 402 for installing a pre-tensioning member, and a steel wire rope for installing photovoltaic panels connected to the pre-tensioning member.

[0041] In one embodiment, the sub-base 2 includes: a second concrete base 201, the top of which is fixedly connected to a protruding shoulder 202, the protruding shoulder 202 being provided in two sets, and the channel steel member 3 being located inside the protruding shoulder 202.

[0042] The channel steel component 3 is restricted by two sets of protruding shoulders 202 to prevent it from detaching from the support of the second concrete base 201.

[0043] In one embodiment, the channel steel component 3 includes: a first beam component 301 and a second beam component 302. The first beam component 301 and the second beam component 302 are distributed in parallel and spaced apart. A connecting frame 303 is fixedly connected between the first beam component 301 and the second beam component 302. There are two connecting frames 303, which are distributed at both ends of the first beam component 301 and the second beam component 302. The first beam component 301 and the second beam component 302 are both channel steel, and the connecting frame 303 is a plate component with a thickness greater than 2 cm.

[0044] To prevent the first beam 301 and the second beam 302 from colliding directly with the top of the sub-base 2, a rubber pad with a thickness of about 5 cm can be added between them.

[0045] In one embodiment, the tie rod 5 includes: a steel wire rope 501, the first end of the steel wire rope 501 is fixedly connected to the bracket 4 through a clamp 502, the second end of the steel wire rope 501 is fixedly connected to the connecting frame 303, and a connecting plate is fixedly connected to the second end of the steel wire rope 501.
