Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic brackets, and in particular relates to a roof photovoltaic module. Background Art

[0002] Solar energy is a clean and renewable energy source, which can improve the energy structure and reduce the dependence on fossil energy. In most parts of the world, photovoltaic power generation is becoming the most important power generation method. Currently, most building roofs are vacant, and installing photovoltaic panels above them can optimize the energy structure and promote sustainable development. However, after installing photovoltaic panels on the roof, since the photovoltaic panels usually need to be erected at a certain height above the roof through photovoltaic brackets and need to be in a certain inclined state to maximize the reception of solar radiation and maximize the conversion of electrical energy. In case of strong wind weather, the inclined photovoltaic panels on the high-rise roof are easily blown by the strong wind and separated from the roof, causing economic losses, and the falling of the photovoltaic panels from the roof will also pose a safety hazard. Therefore, it is necessary to make improvements. Summary of the Invention

[0003] To solve the above-mentioned defects of the prior art, the present application provides a roof photovoltaic module, which can drive the inclined photovoltaic panel to automatically rotate downward to the horizontal state to prevent the photovoltaic panel from being blown off the roof by strong wind in strong wind weather.

[0004] To achieve the above purpose, the present invention adopts the following technologies:

[0005] A roof photovoltaic module, comprising:

[0006] Two groups of support components, symmetrically arranged. Each group of support components includes a plurality of vertically arranged struts arrayed and decreasing in height in sequence. The inner sides of the two lowest vertically arranged struts in the two groups of support components are both hinged with longitudinal mounting rods. The inner sides of the remaining vertically arranged struts are both provided with arc-shaped chutes. Connecting columns are slidably connected in the arc-shaped chutes. The connecting columns are connected to the longitudinal mounting rods on the same side. When the longitudinal mounting rod rotates, the rotation trajectory of the connecting column matches the trajectory of the corresponding arc-shaped chute. When the connecting columns are all at the bottom of the arc-shaped chutes, the longitudinal mounting rod is in a horizontal state;

[0007] A plurality of transverse mounting rods, arrayed above the longitudinal mounting rod along the length direction of the longitudinal mounting rod for installing photovoltaic panels;

[0008] A retracting and releasing mechanism, including a traction mechanism and a traction rope. A transverse strut is provided between the two highest vertically arranged struts. A connecting rod is provided between a pair of longitudinal mounting rods. The connecting rod is arranged at one end of the longitudinal mounting rod close to the highest vertically arranged strut. One end of the traction rope is connected to the traction mechanism, and the other end of the traction rope bypasses the top of the transverse strut and is connected to the connecting rod.

[0009] Further, hinge shafts are connected to the bottoms of the vertical struts, and the hinge shafts are respectively rotatably connected to a plurality of first fixing seats. A synchronizing rod is connected between the hinge shafts connected to the mutually symmetrical vertical struts.

[0010] Further, a plurality of synchronizing rods are respectively connected to one ends of a plurality of push blocks. A receiving groove is formed at the other end of the push block. Connecting shafts are arranged in the receiving grooves. A strip-shaped rod is rotatably connected to the plurality of connecting shafts. One end of the strip-shaped rod is hinged to the telescopic end of a telescopic mechanism, and the fixed end of the telescopic mechanism is hinged to a second fixing seat.

[0011] Further, the strip-shaped rod is arranged below the synchronizing rod. When the telescopic end of the pushing mechanism is fully extended, the vertical strut is in a vertical state. When the telescopic end of the pushing mechanism is fully retracted, the vertical strut rotates downward by a preset angle.

[0012] Further, when the telescopic end of the pushing mechanism retracts, the highest vertical strut rotates in a direction away from the lowest vertical strut.

[0013] Further, blocks are arranged at one ends of the first fixing seats. When the vertical strut is in a vertical state, the block abuts against the vertical strut.

[0014] Further, vertical plates are arranged on one sides of the two highest vertical struts in the two groups of support assemblies. First through holes are formed in the vertical plates. The axial direction of the first through holes is parallel to the length direction of the transverse mounting rod and is used for connecting pin bolts. When the longitudinal mounting rod rotates upward to the maximum extent and a pin bolt is connected in the first through hole, the pin bolt abuts against the bottom of the longitudinal mounting rod.

[0015] Further, a plurality of second through holes with the same diameter as the first through holes are formed in the vertical plate. The plurality of second through holes are arranged below the first through hole and are arranged in an array along the length direction of the vertical plate.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. When a strong wind weather warning is received, the traction mechanism can be controlled in advance to release the traction rope. The longitudinal mounting rod will rotate downward due to its own gravity. When the connecting column on the longitudinal mounting rod abuts against the arc-shaped chute, the mounting rod will no longer rotate downward because at this time the longitudinal mounting rod is in a horizontal state, and the photovoltaic panel above it will also be in a horizontal state. Compared with the photovoltaic panel that always remains in an inclined state, the photovoltaic panel rotated to the horizontal state can effectively prevent it from being blown off the roof by strong wind.

[0018] 2. When the longitudinal mounting rod rotates downward to the horizontal state, the synchronizing rod can be controlled to rotate to control the synchronous downward rotation of multiple pairs of vertical struts, so that while the longitudinal mounting rod remains in a horizontal state, the height is further reduced, thereby further preventing the photovoltaic panel from being blown off by strong wind, and in this state, the longitudinal mounting rod can be locked and cannot rotate upward.

Detailed Embodiments

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will describe the embodiments of the present invention in detail with reference to the drawings. However, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] An embodiment of the present application provides a roof photovoltaic module, as Figures 1-7 shown, including a support assembly, a longitudinal mounting rod 2, a transverse mounting rod 3, a retracting and releasing mechanism, etc.

[0029] Specifically, there are two sets of support components, which are symmetrically arranged with each other. Each set of support components includes a plurality of vertically supporting rods 1 arranged in an array and decreasing in height in sequence. There is a pair of longitudinally mounting rods 2, one end of which is respectively hinged to the inner sides of the two lowest vertically supporting rods 1 in the two sets of support components. Arc-shaped sliding grooves 101 are formed in the inner sides of the remaining vertically supporting rods 1 except the two lowest vertically supporting rods 1. Connecting columns 201 are slidably connected in the arc-shaped sliding grooves 101, and the connecting columns 201 are connected to the longitudinally mounting rods 2 on the same side. When the longitudinally mounting rods 2 rotate, the rotation trajectories of the connecting columns 201 match the trajectories of the corresponding arc-shaped sliding grooves 101. When the connecting columns 201 are all at the bottoms of the arc-shaped sliding grooves 101, the longitudinally mounting rods 2 are in a horizontal state. There are a plurality of transversely mounting rods 3, which are arranged in an array above the longitudinally mounting rods 2 along the length direction of the longitudinally mounting rods 2 for mounting photovoltaic panels. The retracting and releasing mechanism includes a traction mechanism 4 and a traction rope 401. A transverse support rod 5 is provided between the two highest vertically supporting rods 1, and a connecting rod 202 is provided between the pair of longitudinally mounting rods 2. The connecting rod 202 is arranged at one end of the longitudinally mounting rod 2 close to the highest vertically supporting rod 1. One end of the traction rope 401 is connected to the traction mechanism 4, and the other end of the traction rope 401 bypasses the top of the transverse support rod 5 and is connected to the connecting rod 202.

[0030] During actual use, the bottoms of the vertically supporting rods 1 are fixed to the roof, and the photovoltaic panels are installed on the plurality of transversely mounting rods 3. Then, the traction mechanism 4 is controlled to retract the traction rope 401. The traction rope 401 will pull up the pair of longitudinally mounting rods 2 through the connecting rod 202, making the longitudinally mounting rods 2 in an inclined state, and thus the photovoltaic panels thereon are in an inclined state, improving the utilization rate of solar energy. When a strong wind weather warning is received, the traction mechanism 4 is controlled in advance to release the traction rope 401. The longitudinally mounting rods 2 will rotate downward due to their own gravity. When the connecting columns 201 on the longitudinally mounting rods 2 abut against the arc-shaped sliding grooves 101, the mounting rods will no longer rotate downward because at this time the longitudinally mounting rods 2 are in a horizontal state, and the photovoltaic panels above them will also be in a horizontal state. Compared with the photovoltaic panels that always remain in an inclined state, the photovoltaic panels rotated to the horizontal state can effectively prevent being blown off the roof by strong winds.

[0031] Preferably, referring to Figure 1 、 Figure 3 、 Figure 5 ,hinged shafts 102 are connected to the bottoms of the vertically supporting rods 1, and the hinged shafts 102 are respectively rotatably connected to a plurality of first fixing seats 104. A synchronizing rod 103 is connected between the hinged shafts 102 connected to the symmetrically arranged vertically supporting rods 1. Referring to Figure 6, when the longitudinal mounting rod 2 rotates downward to the horizontal state, since the heights of multiple connecting columns 201 are the same at this time, the synchronous rod 103 can be controlled to rotate to control the synchronous downward rotation of multiple pairs of vertical struts 1, so that the longitudinal mounting rod 2 can further reduce its height while maintaining the horizontal state, thereby further preventing the photovoltaic panel from being blown up by strong winds. After the vertical strut 1 rotates downward, the connecting shaft 602 cannot slide upward along the chute, and further, the longitudinal mounting rod 2 and the photovoltaic panel cannot rotate upward, which can improve the stability of the photovoltaic panel in the horizontal state.

[0032] Specifically, refer to Figures 5-7 , multiple synchronous rods 103 are respectively connected to one end of multiple push blocks 6. A receiving groove 601 is formed at the other end of the push block 6. A connecting shaft 602 is provided in each of the receiving grooves 601. A strip-shaped rod 7 is rotatably connected to multiple connecting shafts 602. One end of the strip-shaped rod 7 is hinged to the telescopic end of a telescopic mechanism 8. The fixed end of the telescopic mechanism 8 is hinged to a second fixed seat 801. By controlling the telescopic end of the telescopic mechanism 8 to drive the strip-shaped rod 7 to move, the synchronous rotation of multiple synchronous rods 103 can be controlled, and further, the synchronous rotation of multiple pairs of vertical struts 1 can be controlled, improving the stability of the vertical strut 1 during the rotation process.

[0033] Specifically, refer to Figure 5 , in an implementation manner, the strip-shaped rod 7 is arranged below the synchronous rod 103, avoiding the strip-shaped rod 7 from blocking the lowered transverse mounting rod 3 and the photovoltaic panel, enabling the vertical strut 1 to rotate downward at a larger angle, and further reducing the height of the photovoltaic panel after it is lowered. In this setting, when the telescopic end of the pushing mechanism is fully extended, the vertical strut 1 is in a vertical state. When the telescopic end of the pushing mechanism is fully retracted, the vertical strut 1 rotates downward by a preset angle. More specifically, when the telescopic end of the pushing mechanism retracts, the highest vertical strut 1 rotates in a direction away from the lowest vertical strut 1. Through this setting, it can be avoided that the highest vertical strut 1 rotates towards the adjacent vertical strut 1, and further, it can be avoided that because the vertical strut 1 is too high, it is blocked by the first fixed seat 104 during the downward rotation process, affecting the maximum angle of its downward rotation.

[0034] Preferably, refer to Figure 3 , a stop block 1041 is provided at one end of each of the first fixed seats 104. When the vertical strut 1 is in a vertical state, the stop block 1041 abuts against the vertical strut 1. Since after the traction rope 401 pulls the longitudinal mounting rod 2 upward to the maximum extent, the connecting column 201 will abut against the top of the arc-shaped chute 101, and the connecting column 201 will generate a thrust on the vertical strut 1. By providing the stop block 1041, support can be provided for the vertical strut 1, improving the stability of the vertical strut 1 after the longitudinal mounting rod 2 is pulled up.

[0035] Preferably, refer to Figure 3 , Figure 5, on one side of the two vertical struts 1 with the highest height in the two groups of support components, there are vertical plates 9. The vertical plates 9 are provided with first through holes 901. The axial direction of the first through holes 901 is parallel to the length direction of the transverse mounting rod 3 and is used to connect the pin 10. When the longitudinal mounting rod 2 rotates upward to the maximum limit and the pin 10 is connected in the first through hole 901, the pin 10 abuts against the bottom of the longitudinal mounting rod 2, which can provide support for the longitudinal mounting rod 2, avoid the continuous downward pulling force of the connecting rod 202 on the traction rope 401, and improve the service life of the traction rope 401. Specifically, refer to Figure 5 , the vertical plates 9 are provided with a plurality of second through holes 902 having the same diameter as the first through holes 901. The plurality of second through holes 902 are arranged below the first through holes 901, and the plurality of second through holes 902 are arranged in an array along the length direction of the vertical plates 9. Since the light irradiation angles in different regions are different, it is necessary to adjust the tilt angle of the photovoltaic panel to maximize the received solar radiation. After controlling the longitudinal mounting rod 2 to rotate to the corresponding angle, the pin 10 can be inserted into the second through hole 902 at the corresponding height to provide support for the longitudinal mounting rod 2.

[0036] The above are only the preferred embodiments of the present invention and do not represent the only or limit the present invention. Those skilled in the art should understand that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
