Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a stable photovoltaic bracket with a counterweight mechanism. Background Art

[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of operation: independent operation and grid-connected operation. Photovoltaic is divided into two categories, one is centralized, such as large-scale northwest ground photovoltaic power generation systems; the other is distributed, such as residential rooftop photovoltaic power generation systems. Photovoltaic panels require mounting brackets when installed, so this has led to the emergence of photovoltaic brackets. However, since photovoltaic panels are more commonly used in the northwest and the northwest has strong winds and sand, we need to increase the weight of the brackets to a certain extent to avoid the collapse of the brackets in strong winds. Therefore, the existing stable photovoltaic bracket with a counterweight mechanism has been continuously innovated and developed. Therefore, it can be seen that the current stable photovoltaic bracket with a counterweight mechanism still has some problems.

[0003] For example, patent publication CN216356571U discloses a counterweight-stabilized photovoltaic support. The support comprises a base frame, to which a support is hingedly connected; an adjustable connector is provided on the support frame, to which an auxiliary support rod is hingedly connected; and a box is placed on the base frame, with reinforcement members fixedly mounted at each of the four corners. This utility model proposes a counterweight-stabilized photovoltaic support, which facilitates counterweighting and transportation. The adjustable connector facilitates adjustment of the support position of the auxiliary support rod, allowing for flexible adjustment of the support's operating angle.

[0004] However, when the above device is actually used, although it can support and install the photovoltaic panels, the weight of the weight-increasing device is a fixed weight, which makes it difficult to move the device, thereby bringing great pressure to the workers' carrying work. Therefore, there is an urgent need for a stable photovoltaic bracket with a counterweight mechanism to solve the above problem. Utility Model Content

[0014] Preferably, the top of the L-bottom plate is threadedly connected to a first ground nail, and the top of the auxiliary plate is threadedly connected to a second ground nail.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0027] A stable photovoltaic bracket with a counterweight mechanism includes an L-type base plate 1, which is used to support the device for work. A first extension block 2 is slidably connected to the inside of the L-type base plate 1. The first extension block 2 is used to extend longitudinally, thereby extending and adjusting the size of the device. An auxiliary plate 3 is fixedly connected to one side of the first extension block 2. The auxiliary plate 3 is convenient for connecting the L-type base plate 1 and the first extension block 2, so that the device can form a whole. A weight-increasing box 4 is threadedly connected to the top of the auxiliary plate 3. The weight-increasing box 4 can be disassembled. At the same time, the weight-increasing box 4 is equipped with weight-increasing blocks. The weight-increasing blocks can be added or subtracted according to needs. A placement bin 5 is opened inside the weight-increasing box 4. The placement bin 5 is convenient for placing weight-increasing blocks therein. A top cover 6 is provided on the top of the weight-increasing box 4. The top cover 6 can close the top of the weight-increasing box 4, thereby facilitating the removal of weight-increasing blocks.

[0028] The first extension plate 7 and one side of the L base plate 1 are fixedly connected with the first extension plate 7, which facilitates the device to extend horizontally. A first sliding groove 8 is provided on the top of the first extension plate 7, which facilitates the sliding bolt 10 to slide inside. The inside of the L base plate 1 is slidably connected with the second extension block 9, which can slide inside the first extension plate 7 to adjust the size of the device. The top of the second extension block 9 is fixedly connected with the sliding bolt 10, which facilitates the ability to limit the extension of the second extension block 9. The surface of the sliding bolt 10 is threadedly connected to the limiting nut 11, which can be tightened to fix the second extension block 9 inside the first extension plate 7.

[0029] Furthermore, a second sliding groove 12 is provided on the top of the L-bottom plate 1, and the second sliding groove 12 facilitates the sliding of the supporting triangle block 13 therein. The interior of the second sliding groove 12 is slidingly connected with the supporting triangle block 13, and the supporting triangle block 13 can support the bottom of the support plate 16, thereby performing triangular clamping support on the bottom of the support plate 16, thereby increasing the stability of the device.

[0030] Furthermore, a support block 14 is fixedly connected to the surface of the auxiliary plate 3, and the support block 14 is used to assist the device in installing the photovoltaic panel. An electric telescopic rod 15 is fixedly connected to the inside of the support block 14. As an existing technology, the electric telescopic rod 15 can provide power for the adjustment of the support plate 16.

[0031] Furthermore, the output end of the electric telescopic rod 15 is fixedly connected to a support plate 16, which can be adjusted to adjust the angle of the photovoltaic panel installation support. At the same time, the support plate 16 is a bracket for supporting the installation of the photovoltaic panel, which is convenient for the installation of the photovoltaic panel. The surface of the support block 14 is provided with a third sliding groove 17, which can facilitate the support plate 16 to slide inside.

[0032] Furthermore, a first rotating groove 18 is opened on the top of the L base plate 1, which facilitates the support plate 16 to rotate during adjustment. Rotating blocks 19 are fixedly connected to both sides of the first rotating groove 18, and the rotating blocks 19 are easy to be snapped into the second rotating groove 20.

[0033] Furthermore, second rotation grooves 20 are opened on both sides of the support plate 16, and the rotation block 19 rotates inside the second rotation groove 20. The rotation block 19 can move inside the second rotation groove 20, so that the device can work flexibly.

[0034] Furthermore, two auxiliary block extension blocks 21 are fixedly connected between the support blocks 14, and the two auxiliary block extension blocks 21 are respectively located at the upper and lower parts of the support blocks 14.

The first ground nail 22 and the second ground nail 23 have the same function, which can fix the four corners of the device to the ground, thereby further increasing the stability of the device.

[0036] Working principle: When using the device to stabilize photovoltaic support, the staff first moves the auxiliary plate 3 according to the installation angle, so that the first extension block 2 can be extended, and at the same time, the electric telescopic rod 15 is turned on, so that the electric telescopic rod 15 can drive the support plate 16 to slide in the third sliding groove 17. At the same time, the rotating block 19 can rotate in the second rotating groove 20, so that the support plate 16 can be adjusted to a suitable position, and then push the supporting triangle block 13 so that the supporting triangle block 13 can slide in the second sliding groove 12, and then contact the bottom of the support plate 16, thereby increasing the stability of the support plate 16, and then make an estimate based on the size of the photovoltaic panel, and then screw the limit nut 11, and then move the L bottom plate 1 once, so that the second extension block 9 can be extended, thereby increasing the working length of the device. When the device is deployed, the first ground nail 22 and the second ground nail 23 are screwed to help increase the stability of the device.
