Description

Technical Field

[0001] The present invention relates to a photovoltaic power generation system, in particular to a photovoltaic power generation system based on a flexible bracket and applied in the field of photovoltaic power generation systems. Background Art

[0002] Existing photovoltaic equipment is generally installed on the ground, roof, etc. without obstructions through fixed brackets. However, this traditional installation method occupies a large area and requires a large number of positioning columns. On the one hand, a large amount of metal is used and the installation cost is high. On the other hand, due to the dense arrangement of positioning columns, the space under the photovoltaic panel is difficult to reuse.

[0003] Based on the above problems, a photovoltaic power generation device installed by a flexible bracket has emerged in the prior art. It is suspended between two supporting components by flexible cables and is in a suspended state as a whole. For example, the Chinese patent specification with publication number CN217643281U discloses a flexible bracket distributed photovoltaic power generation system for a sewage treatment plant, and the Chinese patent specification with publication number CN107181446A discloses a point-supported flexible cable photovoltaic bracket and its combination array. Since the number of positioning components is small, the space below it is not easily affected by the positioning columns and can be reused. However, this photovoltaic device installed by a flexible cable has a large span between the two positioning components and is easily affected by natural wind and shakes. When the wind is too strong, the support columns on the positioning components are subjected to a relatively concentrated and large force, which easily causes the support columns to tilt toward the middle, affecting the stability of the photovoltaic device. Summary of the Invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the span between the positioning columns is large, the force on them is relatively concentrated, and they are prone to tilting toward one side of the photovoltaic panel, affecting the stability of the entire photovoltaic system.

[0005] In order to solve the above problems, the present invention provides a photovoltaic power generation system based on a flexible bracket, comprising two groups of support assemblies, two flat cables connected between the two groups of support assemblies, and a plurality of photovoltaic panels evenly hung between the two flat cables, the ends of the flat cables are fixedly connected to inclined cables, the ends of the inclined cables are connected to counterweight balancing assemblies, the counterweight balancing assemblies are buried underground, two long keels are commonly provided at the bottom of the plurality of photovoltaic panels, two T-shaped blocks corresponding to the two long keels are respectively provided between two adjacent photovoltaic panels, the T-shaped blocks and the long keels are fixed by bolts, the two flat cables are respectively located at the vertical angle formed by the two long keels and the photovoltaic panels, the downwardly inclined side ends of the long keels are fixedly connected to a plurality of evenly distributed binding straps, and the plurality of binding straps are tied to the outside of the flat cables; The support assembly includes two columns, a support base fixedly connected to the upper ends of the two columns, and two double vertical angle steels fixedly connected to the upper ends of the support bases. The middle parts of the upper ends of the two double vertical angle steels are connected to the support columns by bolts. The ends of the flat cables movably pass through the support columns, and a locking piece is fastened between the end of the support column away from the photovoltaic panel and the flat cable. A flat plate is fixedly connected to the inner wall of the upper end of the support column. A strength compensation unit is provided inside the support column. The strength compensation unit includes a guide rod fixedly connected to the middle part of the lower end of the flat plate, a reinforcement block provided at the lower end of the flat plate, and two reinforcement strips located at the bottom of the support column. The reinforcement block is sleeved on the outside of the guide rod, and two limit ropes are fixedly connected between the reinforcement block and the flat plate. Guide grooves are opened at the upper ends of the two reinforcement strips close to each other, and the lower ends of the reinforcement block and the guide rod extend into the guide grooves.

[0006] In the above-mentioned photovoltaic power generation system based on the flexible support, through the setting of the strength compensation unit, on the one hand, the verticality of the support column can be monitored in real time, so that it can be detected in time when it is deformed due to excessive force. On the other hand, after the force is deformed, the strength compensation unit can spontaneously decompose, thereby forming an inner lining inside the support column to improve the strength of the support column, effectively suppress the deformation amplitude, and provide sufficient time for the staff to carry out maintenance.

[0007] As a further improvement of the present application, the vertical sections of the double vertical angle steels face multiple photovoltaic panels, and the number of bolts used to fix the horizontal sections of the double vertical angle steels away from the photovoltaic panels and the support base is greater than the number of bolts on the other side.

[0008] As a further improvement of the present application, the reinforcement block includes an upper compensation block fixedly connected to the limiting rope, a lower compensation block located below the upper compensation block, and a lower extension shaft fixedly connected to the lower end of the lower compensation block. The upper compensation block, the lower compensation block and the lower extension shaft all moveably pass through the guide rod, and the lower end of the lower extension shaft contacts the inner wall of the guide groove.

[0009] As a further improvement of the present application, when the two reinforcement strips both conflict with the inner wall of the support column, the distance between the two reinforcement strips is greater than the width of the lower compensation block and the upper compensation block, and electromagnetic plates are fixedly embedded inside the left and right side ends of the support column. When energized, the electromagnetic plates generate magnetic attraction on the reinforcement strips.

[0010] As a further improvement of the present application, a sensing unit is installed at the bottom of the support column. The sensing unit includes a groove dug in the support column away from the bottom of the photovoltaic panel and a laser rangefinder installed in the groove. The laser rangefinder and the limit rope are not on the same vertical plane.

[0011] As another improvement of the present application, a moisture-conducting layer is laid on the bottom of the support column, the power-on circuit of the electromagnetic plate is connected in series with two conductive contact plates, the moisture-conducting layer is connected between the two conductive contact plates, and a sensing unit is provided inside each support column and between the reinforcement strip.

[0012] As another improved supplement to the present application, the sensing unit includes a pre-crushing rod fixedly connected between the inner walls of the support columns and a plurality of filling steel rods fixedly connected to the ends of the reinforcement strips. The pre-crushing rod is wrapped with a flexible mesh sleeve. When viewed from above, the pre-crushing rod and the filling steel rod are misaligned. The pre-crushing rod is made of a hollow brittle material and is filled with water.

[0013] As another improved supplement to the present application, the pre-crushing rod and the replacement steel rod have the same diameter, and the replacement steel rod is a hard fixed structure. The replacement steel rod includes two end fixed segments, a through rod fixedly connected between the two end fixed segments, and a micro-motion segment movably sleeved outside the through rod. Adjacent end fixed segments and micro-motion segments, as well as two micro-motion segments, are in contact with each other, and the diameter of the through rod is smaller than the inner diameter of the micro-motion segment.

[0014] In summary, through the setting of the strength compensation unit, on the one hand, the verticality of the support column can be monitored in real time, so that it can be detected in time when it is deformed by excessive force; on the other hand, after deformation by force, the two reinforcement strips in the strength compensation unit can expand away from each other along the arrangement direction of multiple photovoltaic panels under the deformation signal of the support column, and then the reinforcement block disintegrates longitudinally and is embedded between the two reinforcement strips, so that the reinforcement strips and reinforcement blocks form a stable lining in the support column, thereby effectively enhancing the strength of the support column, effectively suppressing its deformation amplitude, and providing sufficient time for staff maintenance, thereby effectively overcoming the stability problems of photovoltaic equipment with flexible brackets.

DETAILED DESCRIPTION

[0017] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0018] The first implementation method: Figure 1-Figure 3 A photovoltaic power generation system based on a flexible bracket is shown, comprising two groups of support components, two horizontal cables 4 connected between the two groups of support components, and a plurality of photovoltaic panels 3 evenly hung between the two horizontal cables 4. The ends of the horizontal cables 4 are fixedly connected to inclined cables 402, and the ends of the inclined cables 402 are connected to counterweight balancing components, which are buried underground. The counterweight balancing components are existing technologies and are not a technical point of this solution, so they are not described in detail.

[0019] like Figure 4, two long keels 302 are commonly provided at the bottom of multiple photovoltaic panels 3, and two T-shaped blocks 301 corresponding to the two long keels 302 are provided between two adjacent photovoltaic panels 3, and the T-shaped blocks 301 and the long keels 302 are fixed by bolts, and the two flat cables 4 are respectively located at the vertical angle below the two long keels 302 and the photovoltaic panels 3, and the downwardly inclined side ends of the long keels 302 are fixedly connected to multiple evenly distributed binding straps 303, and multiple binding straps 303 are tied to the outside of the flat cables 4. Through the T-shaped blocks 301 and the long keels 302, multiple photovoltaic panels 3 can be connected as one, and a stepped vertical groove can be generated on the back of the inclined photovoltaic panels 3, so that multiple photovoltaic panels 3 can be simultaneously clamped on the two flat cables 4, and then the flat cables 4 can be tied by multiple binding straps 303, thereby ensuring the connection stability between the photovoltaic panels 3 and the flat cables 4.

[0020] like Figure 5 The support assembly includes two columns 1, a support base 21 fixedly connected to the upper ends of the two columns 1, and two double vertical angle steels 23 fixedly connected to the upper ends of the support base 21. The middle parts of the upper ends of the two double vertical angle steels 23 are connected to the support column 22 by bolts. The end of the flat cable 4 movably passes through the support column 22, and a locking member 401 is fastened between the end of the support column 22 away from the photovoltaic panel 3 and the flat cable 4. The locking member 401 is used to limit the position of the flat cable 4, making it difficult to pass through the support column 22 and not prone to lateral sliding, thereby improving the stability of the multiple photovoltaic panels 3 loaded thereon. The two support columns 22 have different heights, which makes the two flat cables 4 between the two support assemblies have different heights, so that the photovoltaic panels 3 placed thereon are inclined.

[0021] The vertical section of the double vertical angle steel 23 faces multiple photovoltaic panels 3, and the number of bolts used to fix the horizontal section of the double vertical angle steel 23 away from the photovoltaic panels 3 and the support seat 21 is greater than the number of bolts on the other side. In windy weather or when used for a long time, due to the gravity of multiple photovoltaic panels 3, the support column 22 away from the photovoltaic panel 3 tends to warp when it is subjected to force. At this time, more fastening bolts are set on the double vertical angle steel 23 on the corresponding side to facilitate improving the connection strength and reducing the warping amplitude.

[0022] like Figure 6 , the inner wall of the upper end of the support column 22 is fixedly connected with a flat plate 201, and the flat plate 201 is parallel to the bottom of the support column 22, and a strength compensation unit is provided inside the support column 22, such as Figure 9The strength compensation unit includes a guide rod 8 fixedly connected to the middle part of the lower end of the plate 201, a reinforcement block 6 arranged at the lower end of the plate 201, and two reinforcement bars 5 located at the bottom of the support column 22. The reinforcement block 6 includes an upper compensation block 61 fixedly connected to the limit rope 601, a lower compensation block 62 located below the upper compensation block 61, and a lower extension shaft 63 fixedly connected to the lower end of the lower compensation block 62. The upper compensation block 61 and the lower compensation block 62 are both made of high-density, high-hardness metal materials, so that they have greater gravity under the same volume and high hardness. They are not easy to deform when subjected to force, so that the reinforcement effect of the support column 22 is better. The upper compensation block 61, the lower compensation block 62 and the lower extension shaft 63 all movably pass through the guide rod 8, and the lower end of the lower extension shaft 63 is connected to the guide rod 8. The inner walls of the guide groove 501 interfere with each other, so that when the two reinforcement bars 5 are not separated from each other, the reinforcement block 6 can be stable under the restriction of the reinforcement bar 5 and is not easy to disintegrate prematurely, which facilitates the subsequent stable entry between the two reinforcement bars 5. The reinforcement block 6 is sleeved on the outside of the guide rod 8, and two limiting ropes 601 are fixedly connected between the reinforcement block 6 and the flat plate 201. The upper ends of the two reinforcement bars 5 close to each other are both opened with guide grooves 501, and the lower ends of the reinforcement block 6 and the guide rod 8 extend into the guide groove 501. The guide rod 8 is used for guiding, so that the reinforcement block 6 can move down smoothly along the guide rod 8 after disintegration, and fall stably between the two reinforcement bars 5, thereby limiting the position of the two reinforcement bars 5, and then effectively ensuring that the strength compensation unit reinforces the strength of the support column 22.

[0023] It is worth noting that when the limiting rope 601 is fully extended, the upper compensation block 61 is lower than the guide groove 501, thereby effectively ensuring that the upper compensation block 61 can be stably embedded between the two reinforcement bars 5, and the upper compensation block 61 will fall to the bottom. Under the restriction of the limiting rope 601, the upper compensation block 61 is located slightly above, which can further improve the stability of the reinforcement bar 5 after the reinforcement block 6 is disintegrated, and maintain a good reinforcement effect on the support column 22.

[0024] like Figure 6 A sensing unit is installed at the bottom of the support column 22. The sensing unit includes a groove dug in the support column 22 away from the bottom of the photovoltaic panel 3 and a laser rangefinder 7 installed in the groove. The laser rangefinder 7 and the limit rope 601 are not on the same vertical plane. Under normal circumstances, the laser beam emitted by the laser rangefinder 7 falls directly on the flat plate 201. When the support column 22 is not deformed, its force data remains stable. When deformation occurs, the support column 22 will deviate toward the side of the photovoltaic panel 3. At this time, the flat plate 201 will also deviate to a certain extent, causing it to no longer be parallel to the bottom of the support column 22, thereby causing obvious data changes in the laser rangefinder 7.

[0025] When the two reinforcing strips 5 are in conflict with the inner wall of the support column 22, the distance between the two reinforcing strips 5 is greater than the width of the lower compensation block 62 and the upper compensation block 61, and the span difference between the two does not exceed 5mm, so that the reinforcing block 6 can smoothly enter between the two reinforcing strips 5 after disintegration, and it is not easy to be difficult to move down due to excessive friction with the reinforcing strip 5. At the same time, a certain margin is provided for the micro-deformation of the reinforcing strip 5, so that the reinforcing block 6 is not easy to be difficult to enter between the two reinforcing strips 5 after disintegration due to the deformation. Electromagnetic sheets are fixedly embedded in the left and right side ends of the support column 22, such as Figure 7-Figure 8 When the electromagnetic sheet is energized, it generates a magnetic attraction force on the reinforcing strip 5. When the data on the laser rangefinder 7 fluctuates, it indicates that the support column 22 is deformed. The electromagnetic sheet is immediately energized, so that when the deformation trend just occurs, the two reinforcing strips 5 are controlled to separate, so that the reinforcing block 6 can be smoothly embedded between the two reinforcing strips 5 after disintegration, thereby making the reinforcing strip 5 and the reinforcing block 6 form a stable lining in the support column 22, making it difficult for the support column 22 to continue to deform.

[0026] It is worth noting that in order to reduce the interference of the electromagnetic sheet on the other reinforcement strip 5 after being energized, magnetic shielding material can be embedded inside the reinforcement strip 5 so that the reinforcement strip 5 is only controlled by the electromagnetic sheet on the same side. At the same time, the ends of the two reinforcement strips 5 close to each other are fixedly connected with magnetic patches, so that in the initial state, the two reinforcement strips 5 can be adsorbed on each other and temporarily become one, which is convenient for temporarily limiting the reinforcement block 6.

[0027] In addition, in order to reduce the influence of the electromagnetic sheet on the current transport generated in the photovoltaic system, a magnetic shielding design can be performed outside the support column 22 according to actual needs.

[0028] In summary, by setting the strength compensation unit, on the one hand, the verticality of the support column 22 can be monitored in real time, so that it can be detected in time when it is excessively deformed by force; on the other hand, Figure 10-11 After being deformed by force, the two reinforcing bars 5 in the strength compensation unit can expand away from each other along the arrangement direction of the multiple photovoltaic panels 3 under the deformation signal of the support column 22, and then the reinforcing block 6 disintegrates longitudinally and is embedded between the two reinforcing bars 5, so that the reinforcing bars 5 and the reinforcing blocks 6 form a stable lining in the support column 22, thereby effectively enhancing the strength of the support column 22, effectively suppressing its deformation amplitude, and providing sufficient time for maintenance for the staff, thereby effectively overcoming the stability problem of the photovoltaic equipment with flexible brackets.

[0029] Second implementation method: This embodiment is based on the first embodiment, and another sensing unit and its related structure are provided, and the rest of the parts are consistent with the first embodiment.

[0030] The bottom of the support column 22 is paved with a moisture-conducting layer made of a water-absorbing material. The power circuit of the electromagnetic plate is connected in series with two conductive contact plates, and the moisture-conducting layer is connected between the two conductive contact plates. Figure 12 and Figure 14 As shown, a sensing unit is provided between the interior of each support column 22 and the reinforcing strip 5. The sensing unit includes a pre-crushed rod 91 fixedly connected between the inner walls of the support column 22 and a plurality of filling steel rods 92 fixedly connected to the ends of the reinforcing strip 5. The pre-crushed rod 91 is wrapped with a flexible mesh, which is mainly used to restrain the fragments after the pre-crushed rod 91 is broken, making it difficult to spread and reducing the impact on the movement of the reinforcing strip 5. Figure 12-13 In a top-down view, the pre-crushed rod 91 is misaligned with the replacement steel rod 92. When the electromagnetic sheet is energized, the reinforcing strips 5 are laterally separated and expanded under the action of the magnetic attraction. The pre-crushed rod 91 is not likely to intercept the multiple replacement steel rods 92. The pre-crushed rod 91 is made of a hollow brittle material and is filled with water. When the support column 22 is bent under force, the pre-crushed rod 91 can break quickly. The water inside it overflows, and then the moisture-conducting layer absorbs water, so that the circuit where the electromagnetic sheet is located is turned on, thereby adsorbing the reinforcing strips 5 and quickly separating them.

[0031] The pre-crushing rod 91 and the replacement steel rod 92 have the same diameter, and the replacement steel rod 92 is a hard fixed structure. The replacement steel rod 92 includes two end fixed segments 921, a through rod 923 fixedly connected between the two end fixed segments 921, and a fine-motion segment 922 movably sleeved outside the through rod 923. The adjacent end fixed segments 921 and fine-motion segments 922, as well as the two fine-motion segments 922, are in contact with each other. The diameter of the through rod 923 is smaller than the inner diameter of the fine-motion segment 922, so that multiple fine-motion segments 922 can be offset to a certain extent under the constraint of the through rod 923. When the reinforcement strip 5 moves toward the pre-crushing rod 91, the multiple replacement steel rods 92 can undergo a certain adaptive deformation when blocked by the broken pre-crushing rod 91, so as to reduce the impact of the crushing of the pre-crushing rod 91 on the movement of the reinforcement strip 5.

[0032] In this embodiment, the flat plate 201 and the support column 22 are detachably connected, for example, by bolts, and the connection between the edge of the flat plate 201 and the support column 22 is sealed to prevent external rainwater from penetrating into the support column 22, thereby preventing the moisture-conducting layer from accidentally getting wet and preventing the strength compensation unit from being accidentally triggered.

[0033] Compared with the first embodiment, this embodiment does not require the data transmission, decision-making and execution process of the laser rangefinder 7 when a deformation trend occurs. After its rupture causes the electromagnetic plate to be energized, the operation of separating the two reinforcement strips 5 from each other can be immediately executed, which can reduce the impact of data transmission delay on the reinforcement of the support column 22. During specific implementation, technical personnel in this field can selectively set it according to actual needs.

[0034] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
