Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support foundations, specifically to a combined photovoltaic support. Background Technology

[0002] Photovoltaics, short for solar photovoltaic power generation system, is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. The photovoltaic support structure, as the bottom support structure of the photovoltaic power generation device, needs to provide sufficiently stable support for the installation and normal operation of the entire photovoltaic system.

[0003] Existing photovoltaic (PV) mounting systems are generally divided into fixed systems and tracking systems. Tracking systems have the ability to adjust the angle of the photovoltaic panels or supporting panels above, allowing the panels to adjust their tilt angle according to sunlight conditions for maximum power generation efficiency. However, existing tracking systems typically adjust the angle using a drive motor, shaft, and associated auxiliary structures, resulting in a relatively large overall weight. In high-altitude areas, due to significant temperature differences, there are often large areas of swamp. Swamp soil is usually moist and loose, with low bearing capacity and is corrosive. The high moisture content and looseness of the soil can cause excessive weight to lead to ground subsidence or uneven deformation. Therefore, more complex construction procedures are required to meet the ground bearing capacity requirements of tracking PV systems in high-altitude and moist soil conditions.

[0004] To address these technical issues, a modular photovoltaic support system is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a modular photovoltaic support system to solve the problem that existing tracking photovoltaic supports, which rely on a drive motor, rotating shaft, and associated auxiliary structures for angle adjustment when facing high-altitude swampy areas, result in a large self-weight.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A modular photovoltaic support system includes:

[0008] Two first bases are arranged side by side below the head of the bearing plate and driven into the ground. The upper surface is provided with a detachable first support tube. The top of the first support tube is provided with a first hinge support. The lower surface of the head of the bearing plate is provided with a hinge shaft that is hinged to the first hinge support.

[0009] Two second bases are arranged side by side below the rear of the support plate and driven into the ground. The upper surface is provided with a detachable second support tube. An outer sleeve is slidably fitted on the outer side of the top of the second support tube. The two second bases are fixedly connected by a horizontal plate at the top of the outer sleeve. The wall of the second support tube is provided with several vertically arranged first tie holes. The wall of the outer sleeve is provided with second tie holes that mate with the first tie holes. The first tie holes and the second tie holes are used for the first tie bolts to pass through.

[0010] A support rod is set on a horizontal plate, and a second hinge support is provided at the top. A rotating block is hinged in the second hinge support. The rotating block has a sliding groove arranged along the axial direction of the bearing plate. A sliding rod is provided on the lower surface of the tail of the bearing plate and is slidably set in the sliding groove.

[0011] Furthermore, it also includes a stiffening plate, one side of which is fixedly connected to the lower surface of the cross plate, and the other side is fixedly connected to the outer wall of the outer sleeve.

[0012] Specifically, the first base and the second base have the same structure, both including a supporting steel pipe, and the top of the supporting steel pipe also has a vertical slot, and the side wall of the vertical slot is provided with a third tie hole; the bottom of the first support pipe and the second support pipe are respectively provided with a fourth tie hole that cooperates with the third tie hole, and the third tie hole and the fourth tie hole are used for the second tie bolt to pass through.

[0013] Furthermore, the supporting steel pipe includes a lower steel pipe and an upper steel pipe, with spiral fins wound around the outside of the lower steel pipe and a vertical slot disposed on the top of the upper steel pipe.

[0014] Furthermore, a concrete platform extending radially outward from the upper steel pipe is cast on the outside of the upper steel pipe.

[0015] Specifically, the slide rod is a U-shape with inwardly recessed sidewalls on both sides, and the longitudinal cross-sectional shape of the slide groove is the same as that of the slide rod.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] This utility model sets up a first base and a second base, and combines and splices the first base and the second base with the head and tail of the bearing plate respectively by hinge. Then, the height of the tail of the bearing plate is adjusted by using an outer sleeve in conjunction with the second base, so as to adjust the angle of the bearing plate, reduce the overall weight of the device, and thus reduce the requirements for ground bearing capacity.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0030] like Figure 1 As shown, a modular photovoltaic support system includes:

[0031] The first base 1 is driven into the ground below the head of the bearing plate 6. The upper surface is provided with a detachable first support tube 101. The top of the first support tube 101 is provided with a first hinge support 102. The lower surface of the head of the bearing plate 6 is provided with a hinge shaft that is hinged to the first hinge support 102.

[0032] The second base 2 is driven into the ground below the head of the bearing plate 6. The upper surface is provided with a detachable second support tube 201. An outer sleeve 202 is slidably sleeved on the outer side of the top of the second support tube 201. The tube wall of the second support tube 201 is provided with a number of vertically arranged first tie holes 203. The tube wall of the outer sleeve 202 is provided with second tie holes 204 that cooperate with the first tie holes 203. The first tie holes 203 and the second tie holes 204 are used for the first tie bolts to pass through.

[0033] Support rod 3 is set at the top of the second support tube 201. The top is provided with a second hinge support 301. A rotating block 302 is hinged in the second hinge support 301. The rotating block 302 has a sliding groove 303 arranged along the axial direction of the bearing plate 6. A sliding rod 304 is provided on the lower surface of the tail of the bearing plate 6 and is slidably arranged in the sliding groove 303.

[0034] The principle of this utility model is as follows: The first base 1 and the second base 2 are driven into the ground one in front of the other along the axial direction of the bearing plate 6. The top of the first base 1 is hinged to the lower surface of the head of the bearing plate 6 via the first support tube 101 and the first hinge support 102. The top of the second base 2 is slidably connected to the sliding rod 304 on the lower surface of the tail of the bearing plate 6 via the sliding groove 303 of the second support tube 201, the outer sleeve 202, the support rod 3, the second hinge support 301, and the rotating block 302. When it is necessary to adjust the angle of the bearing plate 6, the outer sleeve 202 is slidably moved up and down to align the second tie hole 204 at the bottom of the outer sleeve 202 with the first tie hole 203 at different heights. Then, the first tie bolt is passed laterally through the first tie hole 203 and the second tie hole 204 to lock the relative height between the outer sleeve 202 and the second support tube 201. When the height of the outer sleeve 202 changes, the heights of the second hinge support 301 and the rotating block 302 also change accordingly. Since the rotating block 302 can rotate within the second hinge support 301, the direction of the slide groove 303 can change along with the height change, thus maintaining consistency with the slide rod 304 at all times, thereby achieving adjustment of the height of the bearing plate 6. It should be noted that, in order to avoid interference between the lifting force brought by the rise of the outer sleeve 202 and the cooperation between the slide groove 303 and the slide rod 304 when the bearing plate 6 is inclined to a horizontal position, it is necessary to avoid the bearing plate 6 becoming horizontal as much as possible. Otherwise, the bearing plate 6 needs to be manually lifted for adjustment. The first support tube 101 and the second support tube 201 are detachably connected, and the first support tube 101 and the second support tube 201 can be installed after the first base 1 and the second base 2 are driven into the ground, which facilitates the driving of the first base 1 and the second base 2 into the ground.

[0035] In a preferred embodiment, two first bases 1 are arranged side by side below the head of the support plate 6; two second bases 2 are arranged side by side below the tail of the support plate 6, and the two second bases 2 are fixedly connected by a horizontal plate 4 at the top of the outer sleeve 202, and the support rod 3 is arranged on the horizontal plate 4.

[0036] This embodiment provides an arrangement of the first base 1 and the second base 2, specifically, as follows: Figure 1As shown, a square support structure is formed by setting two first bases 1 and two second bases 2 side by side. The two second bases are fixedly connected by the horizontal plate 4 at the top of the outer sleeve 202, which can effectively increase the stability of the bottom support and optimize the stress on the bearing plate 6, helping the bearing plate to maintain balance during angle adjustment.

[0037] As a further embodiment, it also includes a stiffening plate 401, one side of which is fixedly connected to the lower surface of the cross plate 4, and the other side is fixedly connected to the outer wall of the outer sleeve 202.

[0038] This embodiment provides a structure to strengthen the cross plate 4, specifically, as follows: Figure 1 As shown, the stiffening plate 401 can effectively improve the strength of the horizontal plate 4, which helps to improve the stability of the two second bases 2.

[0039] In a preferred embodiment, the first base 1 and the second base 2 have the same structure, both including a supporting steel pipe 501. The top of the supporting steel pipe 501 also has a vertical slot 502, and the side wall of the vertical slot 502 is provided with a third tie hole 503. The bottom of the first supporting pipe 101 and the second supporting pipe 201 are respectively provided with a fourth tie hole that cooperates with the third tie hole 503. The third tie hole 503 and the fourth tie hole are used for the second tie bolt to pass through.

[0040] This embodiment provides a specific structure for the first base 1 and the second base 2, specifically, as follows: Figure 1 and Figure 2 As shown, the supporting steel pipe 501 is the main structure driven into the ground to provide support for the upper structure. The vertical slot 502 is set on the top of the supporting steel pipe 501 and is used to connect the first supporting pipe 101 and the second supporting pipe 201. The first supporting pipe 101 and the second supporting pipe 201 are locked to the vertical slot 502 by the matching third tie hole 503 and the fourth tie hole and the second tie bolt, so as to firmly fix the first supporting pipe 101 and the second supporting pipe 201 in the vertical slot 502.

[0041] As a further embodiment, the supporting steel pipe 501 includes a lower steel pipe 505 and an upper steel pipe 504. The lower steel pipe 505 is surrounded by spiral fins 506, and a vertical slot 502 is disposed on the top of the upper steel pipe 504.

[0042] This embodiment provides a specific structure for supporting the steel pipe 501, specifically, as follows: Figure 1 , Figure 2 and Figure 3As shown, it is divided into an upper steel pipe 504 and a lower steel pipe 505. The spiral fins 506 on the outside of the lower steel pipe 505 can effectively increase the contact area between the supporting steel pipe 501 and the soft soil layer or the soil layer in the swamp area, thereby reducing the contact area pressure, reducing the possibility of settlement or soil deformation, and effectively improving the bearing capacity provided by the supporting steel pipe 501.

[0043] As a further embodiment, a concrete platform 507 extending radially outward from the upper steel pipe 504 is cast on the outside of the upper steel pipe 504.

[0044] This embodiment provides a structure that further increases the bearing capacity of soil, specifically, as follows: Figure 1 , Figure 2 and Figure 3 As shown, after the lower steel pipe 505 supporting the steel pipe 501 is rotated and driven into the ground, a concrete platform 507 is poured on the outside of the upper steel pipe 504. This can protect the upper steel pipe, improve the stress distribution, enhance the corrosion resistance of the upper steel pipe 504, and improve the overall durability of the foundation.

[0045] As a further embodiment, the slide rod 304 is a U-shape with the left and right side walls recessed inward, and the longitudinal cross-sectional shape of the slide groove 303 is the same as the longitudinal cross-sectional shape of the slide rod 304.

[0046] This embodiment provides a specific structure for the slide rod 304 and the slide groove 303. Specifically, as follows: Figure 3 and Figure 4 As shown, both the slide groove 303 and the slide rod 304 have U-shaped cross-sections, and their left and right side walls are concave inward, making the slide rod appear as an inverted Ω shape. This allows the slide groove 303 to limit the slide rod 304, keeping the slide rod 304 always inside the slide groove 303, thereby ensuring the stability of the upper bearing plate 6 throughout the sliding process.

[0047] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.
