[0002] Household photovoltaics are often installed on household roofs, but the shapes of roofs are not exactly the same. For sloping roofs, photovoltaic mounting brackets are usually laid along the sloping roof, with the same angle as the sloping roof, or the photovoltaic installation angle can be changed by designing the bracket structure. However, most of the brackets installed in existing structures need to be customized according to the outer contour of the roof, and the angle of receiving light energy is not easy to adjust immediately. In addition, the stability of the bracket must also be considered to prevent it from being blown down by wind. [Utility Model Content]

[0004] To solve the above technical problems, the utility model adopts the following technical solutions: a rooftop installation mechanism for household photovoltaics, comprising a base and a lifting column assembly vertically arranged on the base, the lifting column assembly comprising at least two first lifting columns arranged on the left side of the base and arranged side by side, and at least two second lifting columns arranged on the right side of the base and arranged side by side, the first lifting column and the second lifting column correspond to each other on the left and right, and the lifting column assembly is connected with a photovoltaic panel installation assembly for installing photovoltaic panels; the first lifting column and the second lifting column are provided with lifting components, and a reverse synchronous drive component is provided between the first lifting column and the second lifting column corresponding to each other on the left and right, and the reverse synchronous drive component is used to synchronously drive the first lifting column and the second lifting column, and the lifting directions of the lifting components on the first lifting column and the second lifting column are opposite.

[0005] Preferably, the reverse synchronous drive assembly includes a drive motor and a transmission shaft disposed on a base, the transmission shaft is connected to a transmission component, the drive motor drives the drive shaft to rotate, and the transmission component drives the lifting component to rise and fall.

[0006] Preferably, the first lifting column and the second lifting column include a sleeve with an inner thread groove on the inner wall, and the lifting component is a screw rod threadably connected to the inner thread groove.

[0007] Preferably, the transmission component is a transverse bevel gear, and the tooth surfaces of the transverse bevel gears at both ends of the transmission shaft are arranged face to face, the lower end of the sleeve is provided with a longitudinal bevel gear, the transverse bevel gear is meshed with the longitudinal bevel gear for transmission, and the sleeves on the first lifting column and the second lifting column rotate in opposite directions.

[0008] Preferably, the photovoltaic panel mounting assembly comprises a card frame and a mounting plate hinged to the card frame.

[0009] Preferably, the card frame is provided with a movable chamber for enabling the mounting plate to rotate up and down; and / or, a rotating cylinder for locking and fixing the mounting plate is installed on the card frame.

[0010] Preferably, the mounting plate is provided with slots, and an extension plate is inserted between the slots of the mounting plates on the left and right sides.

[0011] Preferably, a rectangular slide is provided on the mounting plate, a positioning block is movably connected inside the rectangular slide, a long rod is connected to the outside of the positioning block, the long rod moves left and right along the rectangular slide with the positioning block, a baffle is connected to the outside of the long rod, and a spring is provided between the outside of the long rod and the mounting plate.

[0012] Preferably, a frosted surface layer is provided on one side of the baffle plate that is connected to the long rod.

[0013] Preferably, support frames are fixed at both ends of the left side of the base, and a lap plate is hinged between the two support frames. A third bolt is provided between the support frame and the lap plate, and the third bolt locks the lap plate and the support frame after the lap plate adjusts its angle. The lap plate is connected with a second bolt, and the base is connected with a first bolt. The first bolt and the second bolt are used to install the roof mounting mechanism on the roof.

[0014] The utility model adopts the above technical solution and has the following beneficial effects:

[0015] 1. A reverse synchronous driving assembly is arranged between the first lifting column and the second lifting column corresponding to the left and right sides to drive the lifting component to lift. Since the lifting directions of the lifting components on the first lifting column and the second lifting column are opposite, the photovoltaic panel installation assembly connected to the lifting column assembly can be in a state of left low and right high, left high and right low, or horizontal through the driving adjustment of the reverse synchronous driving assembly, and the photovoltaic panel carried is also the same, which facilitates the adjustment of the form of the photovoltaic panel absorbing light energy and solves the problem that the posture of the photovoltaic panel installed on the roof is inconvenient to adjust after installation.

[0016] 2. The driving motor is used to synchronously drive the first lifting column and the second lifting column, so that the angle of the photovoltaic panel can be accurately adjusted according to the change of the sun's angle.

[0017] 3. Since the tooth surfaces of the transverse bevel gears at both ends of the transmission shaft are arranged face to face, the longitudinal bevel gears of the respective meshing transmissions are in opposite directions, resulting in one sleeve on both sides pushing out the screw rod upward and the other sleeve sinking the screw rod downward, thereby achieving the opposite lifting directions of the first lifting column and the second lifting column; in addition, the advantage of using gear transmission and screw nut lifting is that the transmission accuracy is high, which can realize the precise adjustment of the angle of the photovoltaic panel.

[0018] 4. The mounting plate can be rotated up and down relative to the card frame to keep the mounting plate and the photovoltaic panel parallel and fitted together to ensure stable installation of the photovoltaic panel.

[0019] 5. During the lifting process of the first lifting column and the second lifting column, the mounting plate flips up and down in the movable chamber. After the first lifting column and the second lifting column are lifted, the rotating cylinder locks and fixes the mounting plate to ensure the stable placement of the photovoltaic panel.

[0020] 6. Since slots are reserved on the mounting plate, extension plates are inserted between the slots of the mounting plates on the left and right sides, so that the mounting plates on the left and right sides can rotate synchronously and keep the same angle during the reverse lifting process of the first lifting column and the second lifting column.

[0021] 7. Under the tension of the spring, pull the long rod, and the long rod drives the baffle to press the side of the photovoltaic panel. In addition, the frosted surface can increase the friction between the photovoltaic panel and the baffles on the left and right sides cooperate to clamp the two sides of the photovoltaic panel to ensure that the photovoltaic panel is placed stably and avoid falling.

[0022] 8. When installing the roof mounting mechanism on the roof, first loosen the third bolt on the support frame, adjust the hinge angle on the left side of the base to match the roof shape, then tighten the third bolt again and place the roof mounting mechanism at the upper corner of the gable roof. Finally, tighten the first and second bolts to quickly fix the base and the lap plate to prevent them from sliding off, and also help the roof mounting mechanism adapt to different roof styles.

[0023] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0037] Embodiment 1

[0038] Reference Figures 1 to 6 As shown, this embodiment provides a roof installation mechanism for household photovoltaics, including a base 1 and a lifting column assembly vertically arranged on the base 1, the lifting column assembly includes at least two first lifting columns arranged side by side on the left side of the base, and at least two second lifting columns arranged side by side on the right side of the base, the first lifting columns and the second lifting columns correspond to each other on the left and right, and the lifting column assembly is connected to a photovoltaic panel installation assembly. Here, taking the arrangement of two first lifting columns and two second lifting columns as an example, four lifting columns are arranged at the four corners of a rectangle, and the photovoltaic panel installation assembly connected by the four lifting columns forms a rectangular photovoltaic panel installation space, corresponding to the rectangular shape of the photovoltaic panel. The first lifting column and the second lifting column are both provided with lifting components, and a reverse synchronous drive assembly is provided between the first lifting column and the second lifting column corresponding to each other on the left and right. The reverse synchronous drive assembly is used to synchronously drive the first lifting column and the second lifting column, and the lifting directions of the lifting components on the first lifting column and the second lifting column are opposite.

[0039] Of course, it is understandable that the at least two first lifting columns arranged side by side on the left side of the base have the same lifting speed and height, and the at least two second lifting columns arranged side by side on the right side of the base also have the same lifting speed and height; at the same time, in the entire roof installation mechanism, the lifting speeds of the lifting components on all the first lifting columns and the second lifting columns are the same, but in opposite directions, so that the left and right sides of the photovoltaic panel can achieve the same lifting speed but in opposite directions.

[0040] Therefore, in the above technical solution, a reverse synchronous driving assembly is provided between the first lifting columns and the second lifting columns corresponding to the left and right sides to drive the lifting components to lift and lower. Since the lifting directions of the lifting components on the first lifting columns and the second lifting columns are opposite, the photovoltaic panel mounting assembly connected to the lifting column assembly can be in a state of left low and right high, left high and right low, or horizontal through the driving adjustment of the reverse synchronous driving assembly, and the same is true for the photovoltaic panels carried, which facilitates the adjustment of the form of the photovoltaic panels absorbing light energy and solves the problem that the posture of the photovoltaic panels installed on the roof is inconvenient to adjust after installation.

[0041] As an implementation mode, the reverse synchronous drive assembly includes a drive motor 2 and a transmission shaft 6 provided on a base 1, the transmission shaft 6 is connected with a transmission component, the drive motor 2 drives the drive shaft 6 to rotate, the transmission component drives the lifting component to lift, and the lifting directions of the lifting components on the first lifting column and the second lifting column are opposite. That is, the first lifting column and the second lifting column corresponding to the left and right share a drive motor and a drive shaft. Still taking the setting of two first lifting columns and two second lifting columns as an example, two drive motors need to be set accordingly. The first lifting column and the second lifting column are synchronously driven by a drive motor, and the angle adjustment principle of the prior art is referred to. The drive motor is controlled through program setting, and the angle of the photovoltaic panel can be precisely adjusted according to the change of the sun angle.

[0042] Specifically, the first lifting column and the second lifting column include a sleeve 11 with an internal thread groove 12 on the inner wall, and the lifting component is a screw 24 threadedly connected to the internal thread groove 12. The transmission component is a transverse bevel gear 4, and the tooth surfaces of the transverse bevel gears 4 at both ends of the transmission shaft are arranged face to face, and the lower end of the sleeve 11 is provided with a longitudinal bevel gear 5, and the transverse bevel gear 4 and the longitudinal bevel gear 5 are meshed for transmission. Since the tooth surfaces of the transverse bevel gears at both ends of the transmission shaft are arranged face to face, the longitudinal bevel gears that are meshed for transmission are in opposite directions, resulting in the sleeves on both sides pushing out the screw rod upwards at one end and sinking the screw rod downwards at another end, thereby achieving the opposite lifting directions of the first lifting column and the second lifting column; in addition, the advantage of using gear transmission and screw nut lifting is that the transmission accuracy is high, and the angle of the photovoltaic panel can be accurately adjusted.

[0043] It is understandable that the first lifting column and the second lifting column may also be conventional lifting columns with telescopic tube structures, and each lifting column may also be provided with an independent driving motor.

[0044] As an implementation method, the photovoltaic panel mounting assembly includes a card frame 25 and a mounting plate 17 hinged to the card frame. The mounting plate can rotate up and down relative to the card frame to keep the mounting plate and the photovoltaic panel parallel and fitted to ensure stable installation of the photovoltaic panel.

[0045] Specifically, the clamping frame 25 is reserved with an active chamber 26 for enabling the mounting plate to be turned up and down. A rotating cylinder 20 is installed between the clamping frame 25 and the mounting plate 17. During the lifting process of the first lifting column and the second lifting column, the mounting plate is turned up and down in the active chamber. After the lifting of the first lifting column and the second lifting column is completed, the rotating cylinder locks and fixes the mounting plate to ensure the stable placement of the photovoltaic panel.

[0046] Furthermore, the mounting plate 17 is provided with a slot 19, and an extension plate 18 is inserted between the slots of the mounting plates on the left and right sides. In this way, the mounting plates on the left and right sides can realize synchronous rotation and keep the same angle during the reverse lifting process of the first lifting column and the second lifting column.

[0047] Embodiment 2

[0048] like Figure 4 As shown, compared with the first embodiment, the mounting plate 17 is provided with a rectangular slide 16, the interior of the rectangular slide 16 is movably connected with a positioning block 21, and the outside of the positioning block 21 is connected with a long rod 22, and the two can be welded. The long rod 22 moves left and right along the rectangular slide 16 with the positioning block 212, and the outside of the long rod 22 is connected with a baffle 13, and the two can be welded. Specifically, two long rods 22 are symmetrically welded at both ends of the side of the baffle 13, and the long rod 22 and the baffle 13 form a 90-degree vertical connection structure. A spring 15 is provided between the outside of the long rod 22 and the mounting plate 17. Under the tension of the spring, the long rod is pulled, and the long rod drives the baffle 13 to press the side of the photovoltaic panel, and the baffles on the left and right sides cooperate to clamp the two sides of the photovoltaic panel to ensure that the photovoltaic panel is stably placed to prevent it from falling.

[0049] Furthermore, a fourth bolt 23 is movably connected between the positioning block 21 and one end of the rectangular slideway 16. A frosted surface layer 14 is provided on the side where the baffle plate 13 is connected to the long rod. The frosted surface layer can increase the friction between the baffle plate and the photovoltaic panel to ensure the stable placement of the photovoltaic panel.

[0050] The positioning block 21 is pushed outward along the rectangular slide 16 on one side of the mounting plate 17, and the externally welded baffle 13 is translated by the long rod 22. The same is true for the other side. After the photovoltaic panel is placed between the baffles 13 on both sides, the positioning block 21 can be loosened so that the frosted surface layer 14 can shrink under the tension of the spring 15 and clamp the two sides of the photovoltaic panel, which is convenient for installation and fixation, and can also be quickly disassembled and carried.

[0051] Embodiment 3

[0052] like Figure 1 As shown, on the basis of the above-mentioned embodiment 1 and embodiment 2, in order to install the roof mounting mechanism on the roof, the two ends of the left side of the base 1 are fixed with support frames 7, and a lap plate 9 is hinged between the two support frames 7, and a third bolt 10 is provided between the support frame 7 and the lap plate 9, and the third bolt 10 locks the lap plate 9 and the support frame 7 after the lap plate 9 adjusts the angle. The lap plate 9 is connected with a second bolt 8, and the base 1 is connected with a first bolt 3, and the first bolt 3 and the second bolt 8 are used to install the roof mounting mechanism on the roof.

[0053] When installing the roof mounting mechanism on the roof, first loosen the third bolt 10 on the support frame 7, adjust the hinge angle on the left side of the base 1 to match the roof shape and keep the roof mounting mechanism stable, then tighten the third bolt 10 again, and place the roof mounting mechanism at the upper corner of the gable roof. Finally, tighten the first bolt 3 and the second bolt 8 to quickly fix the base 1 and the lap plate 9 to prevent them from sliding off, and also help the roof mounting mechanism adapt to different roof styles.
