Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to an angle-adjustable photovoltaic bracket. Background Art

[0002] Photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. Since the angle at which the photovoltaic panels are installed on the brackets during the feasibility study phase may not be the optimal angle, small angle adjustments (±5°) are very necessary in actual production. By adjusting the angle of the photovoltaic panels, the power generation efficiency of the photovoltaic panels can be improved.

[0003] For example, the publication number CN106452308A is a fixed and adjustable photovoltaic bracket that can be manually adjusted at multiple angles. It mainly includes photovoltaic modules, pressure blocks, triangular connectors, crossbeams, longitudinal beams, hand cranks and columns. The columns are made of special I-shaped steel columns. The main shaft and the triangular connector can rotate together around the axis of the column top. The crossbeam and the triangular connector are fixedly connected. The crossbeam and the longitudinal beam form a rotating plane. The photovoltaic module is fixed on the longitudinal beam by a pressure block. The hand crank is fixed to the flange of the column by angle steel. The hand crank is connected to the main shaft. When turning the hand crank, it is squeezed inward to release the self-locking state. When the ideal angle is reached, the squeezing of the hand crank ends and the self-locking state is entered under the action of the spring.

[0004] Among them, the above-mentioned existing technologies have the following technical problems: when the existing photovoltaic bracket is manually adjusting the angle, it is not convenient to observe the adjustment angle in real time, which may easily lead to the angle adjustment being too large or too small during the actual angle adjustment process. At the same time, when the photovoltaic bracket is locking and installing the photovoltaic panel, it is not convenient to assist in positioning the photovoltaic panel after placing it on the photovoltaic bracket, which results in the need for external force to assist in lifting the photovoltaic panel when actually locking it, thereby reducing the fixing efficiency between the photovoltaic panel and the photovoltaic bracket.

[0005] Therefore, we proposed an angle-adjustable photovoltaic bracket to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide an angle-adjustable photovoltaic bracket to solve the problem raised in the above background technology that the existing photovoltaic brackets on the market are not convenient for real-time observation of the adjustment angle when manually adjusting the angle, which leads to the phenomenon that the angle adjustment is too large or too small during the actual angle adjustment process. At the same time, when the photovoltaic bracket is used to lock and install the photovoltaic panel, it is not convenient to assist in positioning the photovoltaic panel after placing the photovoltaic panel on the photovoltaic bracket, which leads to the need for external force to assist in lifting the photovoltaic panel when actually locking the photovoltaic panel, thereby reducing the fixing efficiency between the photovoltaic panel and the photovoltaic bracket.

[0007] To achieve the above object, the present invention provides the following technical solution: an angle-adjustable photovoltaic bracket, comprising a positioning pipe pile, a movable seat is installed on the upper end of the positioning pipe pile, and the upper end of the movable seat is fixedly connected to a support arm, the upper end of the support arm is fixedly connected to a connecting arm, and the upper end of the connecting arm is fixedly installed with a photovoltaic panel;

[0008] Also includes:

[0009] A central screw rod is installed inside the support arm, and moving blocks are installed at the front and rear ends of the central screw rod. One end of the moving block extending from the interior of the support arm is connected to each other through a built-in spring and a limit plate.

[0010] A transmission rod is fixedly installed on the movable seat, and the transmission rod is connected to the upper end of the positioning pipe pile through a bearing, and the left end of the transmission rod is fixedly connected to a hand wheel, and a guide pointer is fixedly connected to the transmission rod, and a scale dial is provided on the side of the guide pointer, and the scale dial is fixed to the upper end side of the positioning pipe pile, and a locking screw sleeve is installed on the transmission rod, and a non-slip protrusion is fixedly connected to the side of the locking screw sleeve facing the positioning pipe pile.

[0011] Preferably, the threads at the front and rear ends of the central screw rod have opposite directions, and the central screw rod and the moving block are connected by threads.

[0012] By adopting the above technical solution, the threaded moving blocks can be moved synchronously relative to each other through the reverse threads at the front and rear ends of the central screw rod.

[0013] Preferably, the outer wall of the lower end of the moving block and the inner wall of the support arm are in contact with each other, and the moving block and the support arm are in sliding connection.

[0014] By adopting the above technical solution, the sliding of the moving block on the support arm can prevent the moving block from rotating synchronously with the central screw rod.

[0015] Preferably, the upper end of the moving block is connected to each other through a plurality of built-in springs and a limiting plate, and the limiting plate and the moving block are distributed in parallel.

[0016] By adopting the above technical solution, when the limiting plate contacts the side of the photovoltaic panel, the elastic deformation of the built-in spring can play a clamping and buffering role on the photovoltaic panel.

[0017] Preferably, the guide pointer and the transmission rod are vertically distributed, and the upper end of the guide pointer and the semicircular scale plate are in contact with each other.

[0018] By adopting the above technical solution, the guide pointer can be rotated synchronously by the rotation of the transmission rod, and the rotation angle can be clearly observed by utilizing the rotation of the guide pointer in contact with the surface of the dial.

[0019] Preferably, the locking nut is symmetrically arranged about the transverse center axis of the transmission rod, and the middle portion of the locking nut and the transmission rod are threadedly connected.

[0020] By adopting the above technical solution, the locking screw sleeve can be easily moved on the transmission rod by rotating the locking screw sleeve.

[0021] Preferably, the anti-slip protrusions are evenly distributed on the surface of the locking nut, and the longitudinal section of the anti-slip protrusions is configured as a circular structure.

[0022] By adopting the above technical solution, the contact friction between the locking screw sleeve and the upper end side of the positioning pipe pile can be improved through the anti-slip protrusions evenly distributed on the locking screw sleeve.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the angle-adjustable photovoltaic bracket can facilitate real-time observation of the adjusted angle when adjusting the angle of the photovoltaic panel, thereby avoiding excessive or insufficient angle adjustment, and can provide auxiliary support for the photovoltaic panel when fixing the photovoltaic panel and the photovoltaic bracket;

[0025] 2. A central screw is provided. The rotation of the central screw can make the movable blocks at the front and rear ends move relative to each other. The relative movement of the movable blocks can assist in clamping the front and rear sides of the photovoltaic panel, thereby achieving auxiliary support for the photovoltaic panel. After that, the photovoltaic panel can be conveniently fixed to the connecting arm by bolts;

[0026] 3. A limit plate is set. When the moving block moves to position the photovoltaic panel, the limit plate inside the moving block first contacts the photovoltaic panel after the moving block moves. The elastic deformation of the built-in spring after the limit plate moves can play a clamping and buffering role, avoiding damage to the photovoltaic panel caused by excessive clamping force;

[0027] 4. A transmission rod and a hand wheel are provided. By rotating the hand wheel, the transmission rod can drive the movable seat and the photovoltaic panel thereon to rotate synchronously.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1-6 When manually adjusting the angle of an existing photovoltaic bracket, it is not convenient to observe the adjustment angle in real time, which may easily lead to the angle being adjusted too much or too little during the actual angle adjustment process. In order to solve this technical problem, this embodiment discloses the following technical content;

[0037] An angle-adjustable photovoltaic support comprises a positioning pile 1, a movable seat 2 being mounted on the upper end of the positioning pile 1, the upper end of which is fixedly connected to a support arm 3, the upper end of which is fixedly connected to a connecting arm 4, and the upper end of which is fixedly mounted to a photovoltaic panel 5; a transmission rod 10 being fixedly mounted on the movable seat 2, the transmission rod 10 being connected to the upper end of the positioning pile 1 via a bearing, and a hand-cranked wheel 11 being fixedly connected to the left end of the transmission rod 10, a guide pointer 12 being fixedly connected to the transmission rod 10, and a scale plate 13 being provided on the side of the guide pointer 12, and the scale plate 13 being fixed to the upper side of the positioning pile 1; a locking screw 14 being mounted on the transmission rod 10, and a non-slip protrusion 15 being fixedly connected to the side of the locking screw 14 facing the positioning pile 1. The guide pointer 12 and the transmission rod 10 are arranged vertically, and the upper end of the guide pointer 12 and the semicircular scale plate 13 are in contact with each other. The locking nut 14 is symmetrically arranged about the transverse center axis of the transmission rod 10, and the middle portion of the locking nut 14 is threadedly connected to the transmission rod 10. The anti-slip protrusions 15 are evenly distributed on the surface of the locking nut 14, and the longitudinal section of the anti-slip protrusions 15 is arranged to be a circular structure.

[0038] When the angle of the photovoltaic panel 5 needs to be adjusted, the hand wheel 11 is rotated. After the hand wheel 11 is rotated, the transmission rod 10 fixed to it can drive the movable seat 2 to rotate synchronously. The rotation of the movable seat 2 can make the support arm 3 and the connecting arm 4 at its upper end rotate synchronously, thereby adjusting the angle of the photovoltaic panel 5 on the connecting arm 4. When the transmission rod 10 is rotated, the guide pointer 12 on it can be rotated. The rotation of the guide pointer 12 in contact with the surface of the dial 13 makes it easy to observe the rotation angle in real time. To avoid excessive or insufficient angle adjustment during the adjustment process, after the angle adjustment of the photovoltaic panel 5 is completed, the transmission rod 10 is fixed with external force. At this time, the locking screw sleeve 14 threaded on the transmission rod 10 is twisted to move the locking screw sleeve 14 on the transmission rod 10. The moved locking screw sleeve 14 is tightly pressed against the upper end side of the positioning pipe pile 1, thereby fixing the position of the transmission rod 10 after rotation, and the anti-slip protrusion 15 on the surface of the locking screw sleeve 14 can increase the contact friction with the upper end side of the positioning pipe pile 1.

[0039] Example 2: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Example 1. When the photovoltaic bracket is locking and installing the photovoltaic panel 5, it is not convenient to assist in positioning the photovoltaic panel 5 after placing the photovoltaic panel 5 on the photovoltaic bracket, which results in the need for external force to assist in lifting the photovoltaic panel 5 when actually locking the photovoltaic panel 5, thereby reducing the fixing efficiency between the photovoltaic panel 5 and the photovoltaic bracket. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1-Figure 4 As shown;

[0040] A central screw rod 6 is installed through the interior of the support arm 3, and movable blocks 7 are installed at the front and rear ends of the central screw rod 6. The end of the movable block 7 extending from the interior of the support arm 3 is connected to each other via an internal spring 8 and a limit plate 9. The front and rear ends of the central screw rod 6 have opposite threading directions, and the central screw rod 6 and movable block 7 are threadedly connected. The lower outer wall of the movable block 7 fits against the inner wall of the support arm 3, and the movable block 7 and support arm 3 are connected in a sliding manner. The upper end of the movable block 7 is connected to each other via multiple internal springs 8 and a limit plate 9, and the limit plate 9 and movable block 7 are arranged parallel.

[0041] When installing the photovoltaic panel 5 and the connecting arm 4, place the photovoltaic panel 5 on the connecting arm 4 and rotate the center screw 6. The rotation of the center screw 6 can make the threaded movable block 7 move toward the direction of the photovoltaic panel 5. The photovoltaic panel 5 can be auxiliary clamped by the movement of the movable block 7. After that, the photovoltaic panel 5 and the connecting arm 4 can be conveniently fixed with bolts. When the movable block 7 moves to position the photovoltaic panel 5, the movable block 7 can move so that the limit plate 9 on it first contacts the photovoltaic panel 5. The elastic deformation of the built-in spring 8 after the limit plate 9 is subjected to force can play a clamping and buffering role on the photovoltaic panel 5, thereby avoiding damage to the photovoltaic panel 5 caused by excessive clamping force.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
