[0012] Therefore, the photovoltaic bracket of the present invention can overcome the defect in the prior art that the photovoltaic system cannot directly receive sunlight in most periods of time, which affects the power generation efficiency of the photovoltaic system, and can improve the power generation efficiency of the photovoltaic system.

[0013] In an optional embodiment, the photovoltaic support further includes:

[0014] The weather acquisition module is suitable for acquiring the current weather. The control device is in communication connection with the weather acquisition module and is suitable for controlling the multiple driving mechanisms to lower the heights of the corresponding lifting columns when the weather acquisition module acquires the preset weather.

[0015] Beneficial effects:

[0016] In strong wind weather, the control device can control multiple driving mechanisms to lower the height of the corresponding lifting columns when the weather acquisition module obtains the preset weather, so that the height of the photovoltaic module is as close to the ground as possible, to prevent the photovoltaic module from swinging greatly under the action of strong wind load and causing damage to the photovoltaic module.

[0017] In an optional embodiment, the photovoltaic support further includes:

[0018] The supporting cables are connected between two adjacent lifting columns in each row of lifting columns. The photovoltaic components are arranged on the supporting cables and connected to at least two supporting cables.

[0021] In an optional embodiment, a connection structure is provided at the top end of the lifting column, and the supporting cable is detachably connected to the connection structure.

[0022] In an optional embodiment, the connection structure includes:

[0023] The U-shaped plate includes a first side plate, a second side plate and a connecting plate, wherein the first side plate and the second side plate are connected to two sides of the lifting column respectively, the connecting plate is located above the lifting column and connected between the first side plate and the second side plate, and a first connecting hole and a second connecting hole are formed on the connecting plate;

[0028] In an optional embodiment, there are multiple photovoltaic components, and the multiple photovoltaic components are arranged at intervals.

[0029] Beneficial effects:

[0030] Because the support cable is a flexible material with a certain strength, after the component cable is tensioned, under the weight of the photovoltaic component, the support cable will inevitably produce a certain downward deflection. Under the action of wind load, the wind will produce an upward force or downward pressure on the photovoltaic component, which can easily cause the component to undulate upward or downward. In the photovoltaic bracket of the utility model, multiple photovoltaic components are arranged at intervals, which can prevent the edges of the photovoltaic components from being squeezed against each other when the support cable is deformed, causing deformation or damage to the photovoltaic panel components.

[0033] Beneficial effects:

[0034] With such an arrangement, when the support cable is stretched and relaxed under the weight of the photovoltaic module, the tensioning mechanism can tension the support cable to avoid the support cable generating a large upward force or downward pressure on the photovoltaic module under the action of wind load, causing the photovoltaic module to fluctuate and deform.

[0035] In an optional embodiment, the tensioning mechanism includes:

[0036] A rotation source, which is arranged on the lifting column;

[0041] When the support cable is loosened, the rotation source can drive the drum to rotate in the direction of tightening the support cable, thereby tightening the support cable. After the rotation source stops rotating, the ratchet wheel can abut against the safety gear, thereby locking the drum, preventing the drum from rotating in the direction of loosening the support cable under the tension of the support cable, causing the support cable to loosen.

[0042] In a second aspect, the utility model further provides a photovoltaic system, comprising the photovoltaic support of the first aspect of the utility model.

[0043] Beneficial effects:

[0044] The photovoltaic system of the second aspect of the utility model includes or uses the photovoltaic bracket of the first aspect of the utility model, and thus has its beneficial effect, namely, it can overcome the defect that the photovoltaic system in the prior art cannot directly receive sunlight in most periods of time, causing an impact on the power generation efficiency of the photovoltaic system, and can improve the power generation efficiency of the photovoltaic system.

[0065] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0066] Combine the following Figures 1 to 9 , describing an embodiment of the utility model.

[0067] According to an embodiment of the utility model, on the one hand, a photovoltaic support is provided, comprising a lifting column 1, a photovoltaic module 2, a time module and a control device 3. Among them, a driving mechanism is arranged in the lifting column 1, which is suitable for extending and retracting in the vertical direction under the action of the driving mechanism. The photovoltaic module 2 is connected to a plurality of lifting columns 1, and the plurality of lifting columns 1 are distributed in at least two rows. The time module is suitable for obtaining the current time. The control device 3 is communicatively connected with the time module and the driving mechanism, and is suitable for controlling the driving mechanism to extend and retract the corresponding lifting column 1 according to the current time, so as to adjust the inclination angle of the photovoltaic module 2 relative to the ground.

[0068] The photovoltaic bracket of the utility model includes a time module and a control device 3, wherein the time module is used to obtain the current time, and the control device 3 can obtain the current solar altitude and azimuth based on the current time, and control the driving mechanism to adjust the height of the corresponding lifting column 1 according to the current solar altitude and azimuth, so as to adjust the inclination angle of the photovoltaic component 2 relative to the ground, so that the photovoltaic component 2 can receive sunlight directly, reduce the efficiency loss of the photovoltaic component 2, and thereby improve the power generation efficiency of the photovoltaic system.

[0069] Therefore, the photovoltaic bracket of the present invention can overcome the defect in the prior art that the photovoltaic system cannot directly receive sunlight in most periods of time, which affects the power generation efficiency of the photovoltaic system, and can improve the power generation efficiency of the photovoltaic system.

[0070] As an optional implementation, sunshine information such as the rising and setting time of the sun and the altitude angle and azimuth angle is stored in the control device 3. The control device 3 can control the extension and retraction of the lifting column 1 by controlling the driving mechanism, so that the photovoltaic panel of the photovoltaic module 2 is always facing the direction of light.

[0071] like Figure 2 As shown, in summer, the altitude angle of the sun is relatively large, and the control device 3 can control the lifting column 1 on the north side to rise and the lifting column 1 on the south side to lower, so that the photovoltaic module 2 forms a smaller inclination angle relative to the ground.

[0072] like Figure 3As shown, in winter, the solar altitude angle is small, and the control device 3 can control the lifting column 1 on the north side to be appropriately raised than in summer, and the lifting column 1 on the south side to be appropriately lowered than in summer, so that the inclination angle of the photovoltaic module 2 relative to the ground is increased, so as to face the direction of light.

[0073] like Figure 4 As shown, in the morning, when the sun is in the southeast, the control device 3 can control the lifting column 1 on the east side to be lowered and the lifting column 1 on the west side to be raised, so that the photovoltaic module 2 faces the southeast.

[0074] like Figure 5 As shown, at noon, the control device 3 can control the height of the lifting columns 1 on the south side to be adjusted to be consistent, the height of the lifting columns 1 on the north side to be adjusted to be consistent, and the height of the lifting columns 1 on the north side is slightly higher than the lifting columns 1 on the south side.

[0075] like Figure 6 As shown, in the afternoon, when the sun is in the southwest, the control device 3 can control the lifting column 1 on the east side to rise and the lifting column 1 on the west side to lower, so that the photovoltaic is tilted toward the southwest. At the same time, in any season, the height of the columns at the four corners of each row of components should be adjusted in combination with complex terrain and the sun's altitude and azimuth information.

[0076] The specific telescopic length needs to be adjusted according to the geographical location of the photovoltaic bracket, the surrounding terrain environment, and the model of the photovoltaic bracket. It can be determined through experiments and is well known to those skilled in the art, so it will not be described in detail here.

[0077] The control device 3 may include a programmable logic control component (such as a PLC or a CPU), a memory, and electronic components connected to the programmable logic control component, which are well known to those skilled in the art and will not be described in detail here. The time module preferably includes, but is not limited to, a timer, etc.

[0078] The lifting column 1 is an electrical lifting column 1. As an optional embodiment, the lifting column 1 includes a sleeve and a telescopic rod arranged in sequence along the height direction, the telescopic rod is inserted in the sleeve, and the driving mechanism is suitable for outputting linear motion. The driving mechanism is connected to one of the sleeve and the telescopic rod, and the power output end is connected to the other of the sleeve and the telescopic rod.

[0079] The driving mechanism may be a device capable of outputting linear motion, such as a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, or a combination of a motor and a gear rack.

[0080] As a modified implementation, the lifting column 1 includes a screw extending in the vertical direction and a lifting rod sleeved outside the screw, the lifting rod is threadedly connected to the screw, the top of the lifting rod is used to connect to the photovoltaic module 2, the driving mechanism is suitable for outputting rotation, and the power output end is connected to the screw. Among them, the driving mechanism can be selected as a device capable of outputting rotation, such as a motor, an engine, a hydraulic motor, or a combination of one of them and a reducer.

[0081] In one embodiment, the photovoltaic support further includes a weather acquisition module. The weather acquisition module is adapted to acquire the current weather, and the control device 3 is in communication connection with the weather acquisition module, adapted to control the plurality of driving mechanisms to lower the height of the corresponding lifting columns 1 when the weather acquisition module acquires the preset weather.

[0082] The preset weather is preferably, but not limited to, strong winds, heavy rains, hail, and other weather that may damage the photovoltaic module 2. For example, in strong winds, the control device 3 can control multiple driving mechanisms to lower the height of the corresponding lifting columns 1 when the weather acquisition module acquires the preset weather, so that the height of the photovoltaic module 2 is as close to the ground as possible, so as to prevent the photovoltaic module 2 from swinging greatly under the action of strong wind loads, thereby damaging the photovoltaic module 2.

[0083] In one embodiment, the photovoltaic support further comprises a supporting cable 4 . The supporting cable 4 is connected between two adjacent lifting columns 1 in each row of lifting columns 1 , and the photovoltaic assembly 2 is arranged on the supporting cable 4 and connected to at least two supporting cables 4 .

[0084] Placing the photovoltaic components 2 on the supporting cables 4 can fully utilize the characteristics of the cable structure such as high strength, strong spanning capacity, and tensioning ability, and can facilitate the application of photovoltaic brackets to rugged mountain terrain, reduce the construction of construction platforms and roads on the slope, avoid damage to the natural ecology of the slope, reduce construction costs, shorten the overall construction period, save land resources, and have obvious economic, social and environmental benefits.

[0085] The supporting cable 4 is preferably but not limited to a steel lock or the like.

[0086] In one embodiment, a connection structure 5 is disposed at the top of the lifting column 1 , and the supporting cable 4 is detachably connected to the connection structure 5 .

[0087] As an optional implementation, Figure 7 , Figure 8 and Fig. 9As shown, the connection structure 5 includes a U-shaped plate 501 and a U-shaped bolt 502. The U-shaped plate 501 includes a first side plate 5011, a second side plate 5012 and a connection plate 5013. The first side plate 5011 and the second side plate 5012 are respectively connected to the two sides of the lifting column 1. The connection plate 5013 is located above the lifting column 1 and connected between the first side plate 5011 and the second side plate 5012. The connection plate 5013 is formed with a first connection hole 50131 and a second connection hole 50132. The two ends of the U-shaped bolt 502 pass through the first connection hole 50131 and the second connection hole 50132 respectively, and are threadedly connected to the connection plate 5013. A through hole is formed between the U-shaped plate 501 and the U-shaped bolt 502, and the support cable 4 passes through the through hole. An anti-slip structure is formed at the end of the support cable 4, and the cross-sectional area of ​​the anti-slip structure is larger than the through hole.

[0088] Therefore, a gap for accommodating the end of the U-shaped bolt 502 can be formed between the U-shaped plate 501 and the top end of the lifting column 1, and the operator can adjust the area of ​​the opening by adjusting the width of the U-shaped bolt 502 passing through the U-shaped plate 501 to allow different types of support cables 4 to pass through the opening.

[0089] In one embodiment, the anti-slip structure includes a P-type anchor 401 .

[0090] In one embodiment, there are multiple photovoltaic modules 2, and multiple photovoltaic modules 2 are arranged at intervals. Because the support cable 4 is a flexible material with a certain strength, after the module cable is tensioned, under the self-weight of the photovoltaic module 2. The support cable 4 will inevitably produce a certain downward deflection. Under the action of wind load, the wind will produce an upward lifting force or downward pressure on the photovoltaic module 2, which can easily cause the module to produce an upward or downward undulating deformation. In the photovoltaic bracket of the utility model, multiple photovoltaic modules 2 are arranged at intervals, which can prevent the edges of the photovoltaic modules 2 from being squeezed against each other when the support cable 4 is deformed, causing deformation or damage to the photovoltaic panel module. Preferably, a pressure block 6 is also provided between two adjacent photovoltaic modules 2, and the pressure block 6 can prevent the distance between the two adjacent photovoltaic modules 2 from being reduced, thereby avoiding squeezing of the edges of the photovoltaic modules 2.

[0091] In one embodiment, the photovoltaic support further includes a tensioning mechanism. The tensioning mechanism is connected to the end of the support cable 4 and is suitable for tensioning the support cable 4. By such an arrangement, when the support cable 4 is stretched and relaxed under the deadweight of the photovoltaic module 2, the tensioning mechanism can tension the support cable 4 to avoid the support cable 4 generating a large upward lifting force or downward pressure on the photovoltaic module 2 under the action of wind load, causing the photovoltaic module 2 to fluctuate and deform.

[0092] In one embodiment, the tensioning mechanism includes a rotation source, a drum, a safety gear and a ratchet. The rotation source is arranged on the lifting column 1. The drum is sleeved on the power output end of the rotation source, and the end of the support cable 4 is wound around the drum. The safety gear is sleeved on the drum. The ratchet is formed at one side of the safety gear, and when the drum rotates in the direction of loosening the support cable 4, the ratchet and the safety gear are against each other.

[0093] When the support cable 4 is loosened, the rotation source can drive the drum to rotate in the direction of tightening the support cable 4, thereby tightening the support cable 4. After the rotation source stops rotating, the ratchet wheel can abut against the safety gear, thereby locking the drum, preventing the drum from rotating in the direction of loosening the support cable 4 under the pulling force of the support cable 4, causing the support cable 4 to loosen.

[0094] When implemented in a convertible manner, the reel can also be optionally mounted on a rotating shaft and driven manually. When the reel loses the manually applied force, the ratchet can lock the reel to prevent the reel from rotating in the direction of loosening the support cable 4 under the tension of the support cable 4, causing the support cable 4 to loosen.

[0095] In summary, the flexible photovoltaic bracket of the utility model can overcome the defect in the prior art that the photovoltaic system cannot directly receive sunlight in most periods of time, which affects the power generation efficiency of the photovoltaic system, and can improve the power generation efficiency of the photovoltaic system.

[0096] According to an embodiment of the present utility model, on the other hand, a photovoltaic system is provided, comprising the photovoltaic support involved in the first aspect of the present utility model.

[0097] The photovoltaic system of the second aspect of the utility model includes or uses the photovoltaic bracket of the first aspect of the utility model, and thus has its beneficial effect, namely, it can overcome the defect that the photovoltaic system in the prior art cannot directly receive sunlight in most periods of time, causing an impact on the power generation efficiency of the photovoltaic system, and can improve the power generation efficiency of the photovoltaic system.

[0098] In addition, the photovoltaic system of the utility model makes full use of the characteristics of the cable structure such as high strength, strong spanning capacity, and tensioning. By adopting a new type of pile foundation, this complex structure is conveniently applied to rugged mountainous terrain, reducing the construction of construction platforms and roads on the slope, avoiding damage to the natural ecology of the slope, reducing construction costs, shortening the overall construction period, saving land resources, and having obvious economic, social and environmental benefits.

[0100] (2) The control device 3 only needs to store the light information in advance and has a weather warning function, so that it can control the rotation of a large number of photovoltaic modules 2 at the same time.
