Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation pile foundation, and more specifically, to a photovoltaic power generation pile foundation and a construction method thereof. Background Art

[0002] At present, in the construction of large-scale photovoltaic power stations on flat land, concrete piles are usually used as pile foundations to support photovoltaic brackets, and the photovoltaic bracket system is installed and fixed on prefabricated concrete pile foundations. Concrete piles are widely used in the field of photovoltaic power generation due to their low cost and convenient construction. In addition, the photovoltaic pile foundation is an important part that supports photovoltaic brackets and components. Therefore, the construction quality of the photovoltaic pile foundation will directly affect the installation quality of the photovoltaic brackets and components, and further affect the power generation efficiency of photovoltaic components.

[0003] However, over time, pile foundations may settle due to factors such as soil settlement, humidity changes or temperature fluctuations. This settlement phenomenon will directly affect the stress condition of the photovoltaic support, resulting in uneven stress distribution around the support, which in turn causes the displacement and tilt of the support.

[0004] Specifically, the settlement of the pile foundation will cause some of the support columns to be subjected to excessive pressure, while other parts may be relatively loose, resulting in distortion and deformation of the support structure. This local imbalance not only reduces the overall stability of the support, but may also cause material fatigue or cracks, and ultimately damage the support. If it is not repaired for a long time, the degree of damage may be further aggravated, which will not only affect the power generation efficiency of the photovoltaic system, but also may cause safety hazards, such as support collapse or photovoltaic module shedding.

At the same time, the bearing frame moves synchronously, and the bearing frame is supported by the cooperation of a plurality of plug plates and the insertion gap, thereby compensating for the settlement displacement of the pile basic body, effectively solving the technical problem that the pile foundation may sink due to factors such as soil settlement, humidity change or temperature fluctuation, resulting in uneven stress distribution around the bracket, thereby causing displacement and tilt of the bracket.

DETAILED DESCRIPTION

[0036] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0037] Embodiment 1: According to Figure 1 and Figure 2 As shown, a photovoltaic power generation pile foundation includes a pile basic body 100 and a photovoltaic power generation module 500 arranged above the pile basic body 100, the pile basic body 100 is provided with a first connecting column 200 and a second connecting column 300, and a photovoltaic bracket 600 is installed on the photovoltaic power generation module 500, and the photovoltaic bracket 600 is connected to the second connecting column 300.

[0038] It should be understood that during construction, a hole is drilled using a rotary drilling rig and then cleaned, and a pile driver is used to drive the prefabricated concrete pile base 100 into the soil. After the pile base 100 is constructed, the position, verticality and burial depth of the pile base 100 are inspected to ensure that they meet the design requirements.

[0039] After the construction of the pile base 100 is completed, the first connecting column 200 and the second connecting column 300 are arranged on the pile base 100, and the second connecting column 300 is fixed to the leg part of the photovoltaic bracket 600 with bolt threads to fix the photovoltaic bracket 600, thereby facilitating the installation of the photovoltaic power generation module 500 on the photovoltaic bracket 600.

[0040] Among them, a balancing unit 400 is provided between the pile basic body 100 and the first connecting column 200. When the pile basic body 100 undergoes settlement changes, the balancing unit 400 adaptively changes so that the force points around the photovoltaic bracket 600 can be supported, thereby maintaining the balance around the photovoltaic bracket 600 for stably supporting the photovoltaic power generation module 500.

[0041] Specifically, according to Figure 3 and Figure 4 As shown, the balancing unit 400 includes a connection plate 401 disposed on the pile basic body 100, the connection plate 401 and the pile basic body 100 are threadedly connected by bolts, a base 402 is installed on the connection plate 401, and two groups of side panels 403 are symmetrically distributed on the base 402, and the base 402 and the side panels 403 are fixedly connected. The base 402 is connected to the inside of the side panels 403 to form a connecting cavity. An internal bracket 404 is provided in the connecting cavity, and the internal bracket 404 is fixedly connected to the connection plate 401 and the base 402. In this embodiment, the base 402, the side panels 403 and the internal bracket 404 form a supporting member with the connection plate 401, which is used to stably support the first connecting column 200 and the second connecting column 300, and maintain the stability of the installation of the photovoltaic bracket 600.

[0042] Further, according to Figures 4 to 6 As shown, a carrier 405 is provided between the connection plate 401 and the built-in bracket 404, and the two ends of the carrier 405 pass through the built-in bracket 404 to install the limit block 406, and the built-in bracket 404 is slidably connected with the carrier 405. In this embodiment, the carrier 405 can move up and down inside the built-in bracket 404, so as to adjust the horizontal position of the first connecting column 200 and the second connecting column 300, so as to avoid the horizontal position of the pile basic body 100 to change in value when geological settlement occurs, resulting in deformation of the photovoltaic bracket 600, so that the force points of the photovoltaic bracket 600 are unevenly stressed, thereby affecting the stability of the photovoltaic power generation module 500. In addition, by adjusting the horizontal positions of the first connecting column 200 and the second connecting column 300, the photovoltaic power generation module 500 is not easily damaged, thereby improving the service life of the photovoltaic power generation module 500.

[0043] It should be noted that according to Figures 5 to 7As shown, the first connection column 200 includes a column 201, and the column 201 is installed on the support frame 405. A first spring 407 is provided outside the column 201, and one end of the first spring 407 is fixedly connected to the built-in bracket 404, and the other end of the first spring 407 is fixedly connected to the support frame 405. When the support frame 405 moves upward inside the built-in bracket 404, the first spring 407 generates elastic deformation, providing an outward supporting force to the support frame 405, so as to prevent the support frame 405 from shaking inside the built-in bracket 404.

[0044] Among them, the first guide sleeve 408 and the second guide sleeve 409 are slidably connected to the column 201, and the movement of the first connecting column 200 is guided by the first guide sleeve 408 and the second guide sleeve 409. The setting of the first guide sleeve 408 and the second guide sleeve 409 can prevent the first connecting column 200 from getting stuck when moving. The first guide sleeve 408 is fixedly connected to the built-in bracket 404, and the second guide sleeve 409 is fixedly connected to the base 402.

[0045] according to Figure 8 and Fig. 9 As shown, a receiving plate 410 is symmetrically installed inside the built-in bracket 404, and a plurality of plug plates 411 are slidably connected inside the receiving plate 410. Specifically, the carrier 405 is located between the plurality of plug plates 411 on both sides, and the ends of the plurality of plug plates 411 on both sides that are close to each other abut against the outer wall of the carrier 405. When the carrier 405 moves upward, an insertion gap is formed between the carrier 405 and the connecting plate 401. At this time, the carrier 405 abutting against the plug plates 411 changes in position, causing the plug plates 411 corresponding to the insertion gap to quickly enter the insertion gap, thereby supporting the carrier 405, avoiding deformation of the photovoltaic bracket 600 when settlement occurs, resulting in damage to the photovoltaic power generation module 500.

[0046] Further, according to Fig.10 and Fig.11 As shown, connecting shafts 412 are symmetrically provided on both sides of the plug plate 411 close to the built-in bracket 404, and the connecting shafts 412 are bearing-connected to the built-in bracket 404. A plurality of swing arms 413 are provided on the connecting shaft 412, and sliders 414 are installed at the ends close to each other of the swing arms 413. A slideway 415 is installed on the plug plate 411, and the slideway 415 is slidably connected to the slider 414.

[0047] In addition, one end of the connecting shaft 412 passes through the built-in bracket 404 and extends to the outer surface of the side panel 403. A knob is installed on the end of the connecting shaft 412 that passes through the side panel 403. The connecting shaft 412 can be rotated by the knob to realize manual control. The implementation of manual control facilitates operations such as initial resetting of the swing arm 413.

[0048] Among them, the connecting shaft 412 and the swing arm 413 are connected by a one-way bearing or a ratchet mechanism, so that the swing arm 413 can utilize the one-way bearing or the ratchet mechanism to move toward the carrier 405 without resistance and can rotate normally. When the swing arm 413 needs to be driven to reset, the knob needs to be manually driven to rotate to achieve the reset of the swing arm 413, so that the swing arm 413 can be manually reset while rotating autonomously, which is convenient for changes with changes in the use environment.

[0049] Furthermore, when the swing arm 413 rotates around the connecting shaft 412, it is slidably connected to the slider 414 through the slideway 415 to provide space for the rotation of the swing arm 413, thereby controlling the plug plate 411 to move toward the position of the support frame 405, filling the bottom of the support frame 405, and providing stable support for the photovoltaic bracket 600.

[0050] It should be noted that a second spring 416 is also installed on the swing arm 413, and one end of the second spring 416 away from the swing arm 413 is fixedly connected to the side panel 403, and a partition 417 is provided between every two swing arms 413. The partition 417 can be provided to block each group of second springs 416 to avoid interference between the second springs 416, and the partition 417 is installed on the outer wall of the built-in bracket 404. In this embodiment, the initial state of the second spring 416 is a compressed and force-storing state. When the limit on the plug 411 is released, the elastic restoring force of the second spring 416 controls the plug 411 to be quickly inserted into the bottom of the carrier 405, supports the carrier 405, and improves the stability of the carrier 405.

[0051] according to Figure 7 As shown, a first hydraulic oil chamber 202 is also opened in the column 201, and a first piston rod 203 is slidably connected in the first hydraulic oil chamber 202. The first piston rod 203 is fixedly connected to the second connecting column 300, and a first piston block 204 is installed at one end of the first piston rod 203 away from the second connecting column 300.

[0052] In addition, according to Figure 7 ,as well as Figures 10 to 12 As shown, a plurality of hydraulic oil tanks 418 are installed on the connecting plate 401, and the hydraulic oil tanks 418 correspond to the positions of the swing arm 413, a plurality of second hydraulic oil chambers 419 are opened in the hydraulic oil tank 418, and a second piston block 420 is provided in the second hydraulic oil chamber 419, a second piston rod 421 is installed on the second piston block 420, and a connector 422 is installed at one end of the second piston rod 421 away from the second piston block 420.

[0053] It should be understood that both the first hydraulic oil chamber 202 and the second hydraulic oil chamber 419 are filled with hydraulic oil. When the second piston rod 421 moves in the second hydraulic oil chamber 419, it pushes the second piston block 420 to move synchronously, thereby squeezing the hydraulic oil in the second hydraulic oil chamber 419 and injecting the hydraulic oil into the first hydraulic oil chamber 202, thereby compensating the oil volume of the hydraulic oil in the first hydraulic oil chamber 202, thereby driving the first piston block 204 to move slightly in the first hydraulic oil chamber 202 to reduce the cumulative deviation caused by the plug plate 411 adjusting the horizontal height of the carrier 405.

[0054] Specifically, a guide rod 423 is installed on the connecting head 422, and a guide groove 424 is opened at the end of the swing arm 413 away from the slider 414, and the guide groove 424 is slidably connected to the guide rod 423. Through the movement of the swing arm 413, the guide rod 423 can be driven to slide in the guide groove 424, thereby driving the second piston rod 421 to move synchronously.

[0055] Furthermore, a flow divider 425 is installed on the hydraulic oil tank 418, and a plurality of flow dividers 426 are installed on the flow divider 425, and the flow dividers 426 are respectively connected to the second hydraulic oil chamber 419, and an oil outlet pipe 427 is also installed on the flow divider 425. Two groups of oil inlet pipes 428 are symmetrically installed on the column 201, and two groups of connecting pipe heads 429 are installed on the oil inlet pipes 428, and the positions of the connecting pipe heads 429 correspond to the positions of the oil outlet pipes 427 one by one, and a hose 430 is installed between the connecting pipe heads 429 and the oil outlet pipes 427. In this embodiment, the hydraulic oil in the first hydraulic oil chamber 202 and the second hydraulic oil chamber 419 can be connected by the arrangement of the oil outlet pipe 427 and the oil inlet pipe 428.

[0056] It should be noted that when the swing arm 413 drives the plug plate 411 to move to the insertion gap position below the support frame 405, the end of the swing arm 413 away from the side plate drives the second piston rod 421 to move synchronously, so that the second piston block 420 moves in the second hydraulic oil chamber 419, and the hydraulic oil in the corresponding group of hydraulic oil chambers is pumped into the first hydraulic oil chamber 202, so as to hydraulically compensate for the slight deviation caused by the plug plate 411 adjusting the position of the support frame 405, thereby achieving stable support for the photovoltaic bracket 600.

[0057] according to Fig.13As shown, in other embodiments, a stabilizing unit 700 is further provided in the column 201, and the stabilizing unit 700 includes a buffer oil chamber 701 opened inside the first hydraulic oil chamber 202, and a buffer oil plate 702 is slidably connected in the buffer oil chamber 701, and a third spring 703 is installed between the buffer oil plate 702 and the buffer oil chamber 701. The buffer oil chamber 701, the buffer oil plate 702 and the third spring 703 are always in a standby state, and can absorb sudden external forces, such as vibrations caused by earthquakes or strong winds, to protect the overall structure.

[0058] The inner wall of the column 201 is symmetrically provided with spring grooves 704 , and abutment plates 705 are slidably connected in the spring grooves 704 . A fourth spring 706 is installed between the abutment plates 705 and the spring grooves 704 .

[0059] Specifically, by setting the buffer oil chamber 701, the hydraulic system is divided into two circulation loops. When one loop is compressed by external force, the hydraulic oil will be pressed into the other loop and drive the abutment plate 705 to perform reverse support adjustment, thereby realizing automatic pressure balance and energy recovery.

[0060] When the hydraulic system is adjusted and reaches a balanced state, the outer wall of the first piston rod 203 is abutted and fixed by the abutment plate 705, and the first piston rod 203 is abutted and supported, thereby automatically locking the support position, reducing the burden on the hydraulic system, and avoiding hydraulic oil leakage or fatigue damage.

[0061] Embodiment 2: According to Figures 1 to 13 As shown, a construction method of a photovoltaic power generation pile foundation, used for a photovoltaic power generation pile foundation provided in Example 1, comprises the following steps:

[0062] S1. Drilling a hole with a rotary drilling rig and cleaning the hole at the drilling location;

[0063] S2, using a pile driver to drive the prefabricated concrete pile basic body 100 into the soil;

[0064] S3, detecting the position, verticality and burial depth of the pile basic body 100;

[0065] S4. When settlement occurs, the bottom of the support frame 405 is inserted through the insert plate 411, and the support is adaptively adjusted so that the support is stably supported on all sides;

[0066] S5. While the plug plate 411 is adaptively adjusting the carrier frame 405 , hydraulic oil is injected into the first connecting column 200 and the second connecting column 300 , so that the first connecting column 200 and the second connecting column 300 are adaptively changed to eliminate the slight deviation caused by the adjustment of the plug plate 411 .

[0067] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
