Description

Technical Field

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

[0002] Solar energy is a clean and renewable energy source that can improve the strategic structure of energy and reduce dependence on fossil energy. In most parts of the world, photovoltaic power generation is becoming the most valued power generation method. At present, most building roofs are vacant. Installing photovoltaic panels on them can optimize my country's energy structure and promote sustainable development. However, after installing photovoltaic panels on the roof, because photovoltaic panels usually need to be connected to the roof at a certain height through photovoltaic brackets, and the photovoltaic panels need to be in a certain tilt state, in order to maximize the reception of solar radiation and maximize the conversion of electrical energy. In case of strong winds, the photovoltaic panels tilted on the roof of a high-rise building are easily blown off the roof by strong winds, causing economic losses, and the photovoltaic panels falling from the roof will also cause safety hazards, so it is necessary to make improvements. Summary of the invention

[0003] In order to solve the above-mentioned defects of the prior art, the present application provides a rooftop photovoltaic assembly, which can drive the photovoltaic panels in an inclined state to automatically rotate downward to a horizontal state, thereby preventing the photovoltaic panels from being blown off the roof by strong winds in strong wind weather.

[0004] In order to achieve the above object, the present invention adopts the following technologies: A rooftop photovoltaic assembly, comprising: Two groups of support assemblies are symmetrically arranged, and each group of support assemblies includes a plurality of vertical support rods arranged in an array and with successively decreasing heights. The inner sides of the two vertical support rods with the lowest heights in the two groups of support assemblies are hinged with longitudinal mounting rods, and the inner sides of the remaining vertical support rods are provided with arc-shaped slide grooves, and connecting columns are slidably connected in the arc-shaped slide grooves. The connecting columns are connected to the longitudinal mounting rods on the same side. When the longitudinal mounting rods rotate, the rotation trajectory of the connecting columns matches the trajectory of the corresponding arc-shaped slide grooves. When the connecting columns are at the bottom of the arc-shaped slide grooves, the longitudinal mounting rods are in a horizontal state; A plurality of transverse mounting rods are arranged in an array above the longitudinal mounting rods along the length direction of the longitudinal mounting rods, and are used to install photovoltaic panels; The retracting and releasing mechanism includes a traction mechanism and a traction rope. A transverse support rod is provided between the two highest longitudinal mounting rods, and a connecting rod is provided between a pair of longitudinal mounting rods. The connecting rod is provided at one end of the longitudinal mounting rod close to the highest vertical support rod. One end of the traction rope is connected to the traction mechanism, and the other end of the traction rope passes around the top of the transverse support rod and is connected to the connecting rod.

[0005] Furthermore, the bottoms of the vertical struts are all connected with hinge shafts, which are rotatably connected to the plurality of first fixing seats respectively, and synchronization rods are connected between the hinge shafts connected on the mutually symmetrical vertical struts.

[0006] Furthermore, multiple synchronization rods are respectively connected to one end of multiple push blocks, and a accommodating groove is opened at the other end of the push block. A connecting shaft is provided in the accommodating groove. A strip rod is rotatably connected to the multiple connecting shafts, one end of the strip rod is hinged to the telescopic end of a telescopic mechanism, and the fixed end of the telescopic mechanism is hinged to a second fixed seat.

[0007] Furthermore, the strip rod is arranged below the synchronization rod, and when the telescopic end of the pushing mechanism is fully pushed out, the vertical support rod is in a vertical state, and when the telescopic end of the pushing mechanism is fully retracted, the vertical support rod rotates downward by a preset angle.

[0008] Furthermore, when the telescopic end of the pushing mechanism is retracted, the vertical support rod with the highest height rotates in a direction away from the vertical support rod with the lowest height.

[0009] Furthermore, a stopper is provided at one end of the first fixing seat, and when the vertical support rod is in a vertical state, the stopper abuts against the vertical support rod.

[0010] Furthermore, a vertical plate is provided on one side of the two vertical support rods with the highest height in the two groups of support assemblies, and a first through hole is opened on the vertical plate. The axial direction of the first through hole is parallel to the length direction of the transverse mounting rod and is used to connect a pin. When the longitudinal mounting rod is rotated upward to the maximum limit and a pin is connected to the first through hole, the pin abuts against the bottom of the longitudinal mounting rod.

[0011] Furthermore, a plurality of second through holes having the same diameter as the first through holes are formed on the vertical plate, the plurality of second through holes are arranged below the first through holes, and the plurality of second through holes are arranged in an array along the length direction of the vertical plate.

[0012] The beneficial effects of the present invention are: 1. When encountering a strong wind weather warning, 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 slide groove, the mounting rod will no longer rotate downward. Because the longitudinal mounting rod is in a horizontal state at this time, the photovoltaic panel above it will also be in a horizontal state. Compared with the photovoltaic panel that always maintains a tilted state, the photovoltaic panel that rotates to a horizontal state can effectively avoid being blown off the roof by strong winds.

[0013] 2. When the longitudinal mounting rod is rotated downward to a horizontal state, the synchronous rod can be controlled to rotate to control multiple pairs of vertical support rods to rotate downward synchronously, so that the longitudinal mounting rod can be further lowered while maintaining a horizontal state, thereby further preventing the photovoltaic panel from being blown up by strong winds. In this state, the longitudinal mounting rod can be locked and cannot be rotated upward. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] The present application embodiment provides a rooftop photovoltaic assembly, such as Figure 1-Figure 7 As shown, it includes a support assembly, a longitudinal mounting rod 2, a transverse mounting rod 3, a retractable mechanism, etc.

[0024] Specifically, the support components are divided into two groups and are symmetrically arranged with each other. Each group of support components includes a plurality of vertical support rods 1 arranged in an array and with successively decreasing heights. The longitudinal mounting rods 2 are a pair, one end of which is respectively hinged to the inner side of the two vertical support rods 1 with the lowest heights in the two groups of support components. The inner sides of the remaining vertical support rods 1 except the two vertical support rods 1 with the lowest heights are provided with arc-shaped slide grooves 101, and connecting columns 201 are slidably connected in the arc-shaped slide grooves 101. The connecting columns 201 are connected to the longitudinal mounting rods 2 on the same side. When the longitudinal mounting rods 2 rotate, the rotation trajectory of the connecting columns 201 matches the trajectory of the corresponding arc-shaped slide grooves 101. When the connecting columns 201 are all at the bottom of the arc-shaped slide groove 101, the longitudinal mounting rod 2 is in a horizontal state; there are multiple transverse mounting rods 3, which are arranged in an array above the longitudinal mounting rod 2 along the length direction of the longitudinal mounting rod 2 for installing 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 longitudinal mounting rods 2, a connecting rod 202 is provided between a pair of longitudinal mounting rods 2, and the connecting rod 202 is provided at one end of the longitudinal mounting rod 2 close to the highest vertical support 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 passes around the top of the transverse support rod 5 and is connected to the connecting rod 202.

[0025] During actual use, the bottom of the vertical support rod 1 is fixed to the roof, and the photovoltaic panels are installed on multiple horizontal mounting rods 3. Then the traction mechanism 4 is controlled to retract the traction rope 401, and the traction rope 401 will pull up a pair of longitudinal mounting rods 2 through the connecting rod 202, so that the longitudinal mounting rod 2 is in an inclined state, and then the photovoltaic panels thereon are in an inclined state, thereby improving the utilization rate of solar energy. When encountering a strong wind weather warning, the traction mechanism 4 is controlled in advance to release the traction rope 401, and the longitudinal mounting rod 2 will rotate downward due to its own gravity. When the connecting column 201 on the longitudinal mounting rod 2 abuts against the arc-shaped slide groove 101, the mounting rod no longer rotates downward, because the longitudinal mounting rod 2 is in a horizontal state at this time, and the photovoltaic panel above it will also be in a horizontal state. Compared with the photovoltaic panel that always remains in a tilted state, the photovoltaic panel rotated to a horizontal state can effectively avoid being blown off the roof by strong winds.

[0026] Preferably, see Figure 1 , Figure 3 , Figure 5 The bottom of each vertical support rod 1 is connected with a hinge shaft 102, and the hinge shaft 102 is rotatably connected to a plurality of first fixing seats 104 respectively. A synchronization rod 103 is connected between the hinge shafts 102 connected to the mutually symmetrical vertical support rods 1. Figure 6When the longitudinal mounting rod 2 is rotated downward to a horizontal state, because the heights of the multiple connecting columns 201 are the same at this time, the synchronization rod 103 can be controlled to rotate to control the multiple pairs of vertical support rods 1 to rotate downward synchronously, so that the longitudinal mounting rod 2 can be further lowered while maintaining a horizontal state, thereby further preventing the photovoltaic panel from being blown up by strong winds. After the vertical support rod 1 is rotated downward, the connecting shaft 602 cannot slide upward along the slide groove, thereby preventing the longitudinal mounting rod 2 and the photovoltaic panel from rotating upward, which can improve the stability of the photovoltaic panel in a horizontal state.

[0027] For details, see Figure 5-Figure 7 , multiple synchronization rods 103 are respectively connected to one end of multiple push blocks 6, and the other end of the push block 6 is provided with a receiving groove 601, and each receiving groove 601 is provided with a connecting shaft 602. A strip rod 7 is rotatably connected to multiple connecting shafts 602, and one end of the strip rod 7 is hinged to the telescopic end of a telescopic mechanism 8, and 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 rod 7 to move, multiple synchronization rods 103 can be controlled to rotate synchronously, thereby making multiple pairs of vertical support rods 1 rotate synchronously, thereby improving the stability of the vertical support rods 1 during rotation.

[0028] For details, see Figure 5 In one embodiment, the strip bar 7 is arranged below the synchronization bar 103 to prevent the strip bar 7 from blocking the lowered horizontal mounting bar 3 and the photovoltaic panel, so that the vertical support rod 1 can rotate downward at a larger angle, thereby making the photovoltaic panel lower after being lowered. Under this setting, when the telescopic end of the pushing mechanism is fully pushed out, the vertical support rod 1 is in a vertical state, and when the telescopic end of the pushing mechanism is fully retracted, the vertical support rod 1 rotates downward at a preset angle. More specifically, when the telescopic end of the pushing mechanism is retracted, the vertical support rod 1 with the highest height rotates in a direction away from the vertical support rod 1 with the lowest height. Through this setting, the vertical support rod 1 with the highest height can be prevented from rotating toward the vertical support rod 1 adjacent to it, thereby preventing the vertical support rod 1 from being blocked by the first fixing seat 104 during the downward rotation process due to its excessive height, thereby affecting its maximum downward rotation angle.

[0029] Preferably, see Figure 3 , a stopper 1041 is provided at one end of the first fixing seat 104, and when the vertical support rod 1 is in a vertical state, the stopper 1041 abuts against the vertical support rod 1. Because after the traction rope 401 pulls the longitudinal mounting rod 2 upward to the maximum, the connecting column 201 abuts against the top of the arc-shaped slide groove 101, and the connecting column 201 generates a thrust on the vertical support rod 1. By setting the stopper 1041, support can be provided for the vertical support rod 1, thereby improving the stability of the vertical support rod 1 after the longitudinal mounting rod 2 is pulled up.

[0030] Preferably, see Figure 3 , Figure 5, one side of the two vertical support rods 1 with the highest height in the two sets of support components is provided with a vertical plate 9, and a first through hole 901 is opened on the vertical plate 9. The axial direction of the first through hole 901 is parallel to the length direction of the horizontal mounting rod 3, and is used to connect the pin 10. When the longitudinal mounting rod 2 is rotated 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, prevent the traction rope 401 from being continuously pulled downward by the connecting rod 202, and improve the service life of the traction rope 401. For details, refer to Figure 5 , a plurality of second through holes 902 having the same diameter as the first through hole 901 are provided on the vertical plate 9, the plurality of second through holes 902 are provided below the first through hole 901, and the plurality of second through holes 902 are arranged in an array along the length direction of the vertical plate 9. Because the illumination angles in different regions are different, it is necessary to adjust the inclination angle of the photovoltaic panel to maximize the amount of solar radiation received. After the longitudinal mounting rod 2 is controlled 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.

[0031] The above description is only a preferred embodiment of the present invention, and is not intended to be the only one or to limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
