Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, and in particular to a self-controlled photovoltaic panel lifting device. Background Art

[0002] Solar energy is a clean, renewable energy source that is increasingly favored by people. Converting solar energy into electricity that meets various human needs is an effective way to utilize solar energy. Existing solar panels have always had a low photovoltaic conversion rate, especially in mountainous areas with many trees. At present, when installing solar photovoltaic panels, they are directly installed on the roof or the ground without any device that can adjust the height. This leads to the shadow of the trees easily shining on the solar photovoltaic panels as the sun moves in areas with many trees. The automatic photovoltaic panel lifting device is a mechanical device specially designed for solar photovoltaic power generation systems. The device is mainly used to automatically adjust the solar panels to the optimal solar radiation angle to improve the efficiency of photovoltaic power generation.

[0003] Among them, it was found through searching that the patent application number CN201720705694.8 discloses a lifting type solar photovoltaic panel adjustment device, including a solar photovoltaic panel, which is installed on the top of a fixed plate, and a plurality of telescopic frames and compression springs are arranged below the fixed plate, and a plurality of connecting members are fixed on the lower end surface of the fixed plate, and the telescopic frames and the compression springs are connected to the connecting members through axle pins, and the telescopic frames are arranged in a hollow column, and the bottom end of the compression spring is fixed in a fixed tube;

[0004] When this structure is in use, by setting a telescopic frame and a compression spring, when the telescopic frame and the compression spring are extended, the height of the solar photovoltaic panel can be increased, and when the telescopic frame and the compression spring are lowered, the height of the solar photovoltaic panel can be lowered. However, when this structure is in use, it is difficult to ensure the stability of the solar panel when it is being raised or lowered, which makes the solar panel easy to shake, resulting in low stability. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a self-controlled photovoltaic panel lifting device to solve the problem of poor stability of the solar panel during the lifting process in the prior art.

[0007] a first folding frame connected between the support base and the mounting seat;

[0008] A second folding frame, the second folding frame is connected between the support base and the mounting seat and is arranged opposite to the first folding frame;

[0009] A telescopic driver is arranged on the supporting base and its telescopic action end is connected between the first folding frame and the second folding frame to drive the first folding frame and the second folding frame to expand or contract synchronously.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The self-controlled photovoltaic panel lifting device installs the photovoltaic panel on a mounting seat, and the telescopic driver is telescopically adjusted to drive the first folding frame and the second folding frame to expand or contract synchronously to stably adjust the height of the mounting seat, so that the photovoltaic panel can be stably adjusted during the height adjustment process.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below through specific embodiments:

[0021] like Figure 1-Figure 6 As shown, an embodiment of the present invention proposes a self-controlled photovoltaic panel lifting device, including a support base 1, a mounting seat 2 for mounting a photovoltaic panel, and a lifting frame connected between the support base 1 and the mounting seat 2, the lifting frame including a first folding frame 4, a second folding frame 5 and a telescopic drive 8, the first folding frame 4 is connected between the support base 1 and the mounting seat 2; the second folding frame 5 is connected between the support base 1 and the mounting seat 2 and is arranged opposite to the first folding frame 4; the telescopic drive 8 is arranged on the support base 1 and its telescopic action end is connected between the first folding frame 4 and the second folding frame 5 to drive the first folding frame 4 and the second folding frame 5 to expand or contract synchronously.

[0022] The self-controlled photovoltaic panel lifting device installs the photovoltaic panel on the mounting seat 2, and the telescopic drive 8 is telescopically adjusted to drive the first folding frame 4 and the second folding frame 5 to expand or contract synchronously to stably adjust the height of the mounting seat 2, so that the photovoltaic panel can be stably adjusted during the height adjustment process.

[0023] In order to better understand this solution, the structure will be further optimized below.

[0024] like Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, a self-controlled photovoltaic panel lifting device, wherein the mounting seat 2 includes a reinforcing support frame 21 and a supporting cross plate 22, the reinforcing support frame 21 is connected to both the first folding frame 4 and the second folding frame 5; the supporting cross plate 22 has multiple and detachable connections in the cavity formed on the inner side of the reinforcing support frame 21.

[0025] In this embodiment, the reinforcing support frame 21 is square, and the supporting horizontal plate 22 is arranged inside the reinforcing support frame 21 to improve the structural strength of the reinforcing support frame 21 and facilitate stable support of the photovoltaic panel. The supporting horizontal plate 22 can be connected to the reinforcing support frame 21 by clamping or screwing.

[0026] Furthermore, the mounting seat 2 further comprises elastic clamping blocks 23 , and there are a plurality of elastic clamping blocks 23 disposed on the supporting cross plate 22 and the reinforcing bracket 21 . The plurality of elastic clamping blocks 23 cooperate to form a clamping mounting position located at the top of the reinforcing bracket 21 .

[0027] In this embodiment, there are six elastic clamps 23 divided into two rows, and the position between the two rows of elastic clamps 23 is the clamping installation position; when installing the photovoltaic panel, it is placed in the clamping installation position and fixed by the two rows of elastic clamps 23, and the connection method is simple.

[0028] like Figure 1 , Figure 4, Figure 5 as well as Figure 6 As shown, according to another embodiment of the present invention, a self-controlled photovoltaic panel lifting device, wherein the top of the first folding frame 4 and the top of the second folding frame 5 both have two top side connecting ends that move toward or away from each other, the two top side connecting ends on the same side of the first folding frame 4 and the second folding frame 5 are connected by a horizontal axis 7, the horizontal axis 7 is rotationally connected to the mounting seat 2, and the two top side connecting ends on the same side of the first folding frame 4 and the second folding frame 5 are slidingly connected to the mounting seat 2.

[0029] Here, the cross bar improves the assembly stability of the first folding frame 4 and the second folding frame 5 on the one hand, and is conducive to the synchronous movement of the first folding frame 4 and the second folding frame 5 on the other hand; specifically, the cross axis 7, the first folding frame 4 and the second folding frame 5 are connected in cooperation with the reinforcing support frame 21 in the mounting seat 2, and the connection method makes the first folding frame 4 and the second folding frame 5 not restricted during the expansion or contraction process.

[0030] Meanwhile, the connection mode between the first folding frame 4 and the second folding frame 5 and the supporting base 1 may refer to the connection mode between the first folding frame 4 and the second folding frame 5 and the mounting seat 2 .

[0031] like Figure 1 and Figure 4 As shown, according to another embodiment of the present invention, in the self-controlled photovoltaic panel lifting device, the telescopic action end of the telescopic drive 8 is detachably connected to a positioning rod 6 connected between the first folding frame 4 and the second folding frame 5.

[0032] When the telescopic driver 8 is telescopically adjusted, the first folding frame 4 and the second folding frame 5 are synchronously expanded or contracted by driving the positioning rod 6 to move. The connection between the telescopic end of the telescopic driver 8 and the positioning rod 6 can be a shaft pin movable connection.

[0033] like Figure 1 and Figure 3 As shown, according to another embodiment of the present invention, a self-controlled photovoltaic panel lifting device is provided, wherein the support base 1 is provided with a reinforcing frame 10, the reinforcing frame 10 is provided with an inclined rod 9, and the telescopic drive 8 is detachably connected to the inclined rod 9.

[0034] In this embodiment, the support base 1 is a square frame structure, and the reinforcing frame 10 is arranged inside the square frame structure to improve the structural strength of the support base 1. At the same time, the inclined rod 9 provides an installation position for the telescopic drive 8. The inclined rod 9 and the telescopic drive 8 can also be movably connected by an axle pin. Specifically, the telescopic drive 8 can be a hydraulic rod.

[0035] like Figure 1 , Figure 5as well as Figure 6 As shown, according to another embodiment of the present invention, a self-controlled photovoltaic panel lifting device is provided, wherein a plurality of supporting vertical rods 11 are arranged along the vertical direction on the top of the supporting base 1, and when the first folding frame 4 and the second folding frame 5 are retracted, the plurality of supporting vertical rods 11 are supported on the bottom of the mounting seat 2.

[0036] In this embodiment, there are four supporting vertical rods 11. When the telescopic drive 8 contracts to drive the first folding frame 4 and the second folding frame 5 to contract synchronously until the bottom of the mounting seat 2 abuts against the four supporting vertical rods 11, the telescopic drive 8 stops running. At this time, the automatic photovoltaic panel lifting device is in the storage state to ensure the stability of the automatic photovoltaic panel lifting device in the storage state. Specifically, when the automatic photovoltaic panel lifting device is in the storage state, the reinforcing support frame 21 in the mounting seat 2 abuts against the four supporting vertical rods 11.

[0037] The operation of the self-controlled photovoltaic panel lifting device during lifting is as follows:

[0038] The hydraulic rod is started, and the telescopic end of the hydraulic rod drives the positioning rod 6 to drive the first folding frame 4 and the second folding frame 5 to fold or unfold. The first folding frame 4 and the second folding frame 5 drive the mounting seat 2 to move upward or downward to adjust the height of the photovoltaic panel.

[0039] In order to improve the stability of the automatic photovoltaic panel lifting device during use, an anti-slip structure is provided at the bottom of the support base 1. However, in order to enable the automatic photovoltaic panel lifting device to remain stable on a horizontal ground or an inclined bottom surface, two different structures are designed for the anti-slip structure.

[0040] The automatic photovoltaic panel lifting device is stably placed on a flat ground. Figure 5 As shown, according to another embodiment of the present invention, in the self-controlled photovoltaic panel lifting device, the anti-skid structure is an anti-skid bottom frame 121 arranged at the bottom of the supporting base 1.

[0041] For the self-controlled photovoltaic panel lifting device to be stably placed on an inclined ground, such as a 45-degree slope, the anti-slip bottom frame 121 cannot stably place the self-controlled photovoltaic panel lifting device, and another structural design can be adopted for the anti-slip structure, such as Figure 6 and Figure 7As shown, according to another embodiment of the present invention, a self-controlled photovoltaic panel lifting device, in this case, the anti-skid structure includes a connecting plate 131, a transmission wheel 132, a support belt 133 and a receiving box 134, wherein the connecting plates 131 have two and are arranged in parallel and spaced apart at the bottom of the supporting base 1; the transmission wheels 132 have two and are rotatably connected between the two connecting plates 131, and the two transmission wheels 132 are distributed at both ends of the length direction of the connecting plate 131; the support belt 133 is transmission-connected between the two transmission wheels 132 and the bottom of the support belt 133 is passed through the bottom of the two connecting plates 131 to contact the ground; the receiving box 134 is fixedly arranged between the two connecting plates 131 and its bottom end is open to slide against the top of the support belt 133, and an adhesive is stored in the receiving box 134.

[0042] The bottom of the container box 134 is designed to be open and slide against the top of the support belt 133. On the one hand, the bottom of the container box 134 is sealed by the top of the support belt 133, and the liquid adhesive can be stably stored in the container box 134; on the other hand, the top of the support belt 133 can be coated with the liquid adhesive. When the automatic photovoltaic panel lifting device needs to be stably placed on the inclined surface, one of the transmission wheels 132 is rotated to rotate the top section of the support belt 133 to its bottom, and then contact the inclined surface. Since there is liquid adhesive on the top section of the support belt 133, the liquid adhesive is used to form an adhesive force between the support belt 133 and the inclined surface to ensure that the automatic photovoltaic panel lifting device is stably placed on the inclined surface; during the rotation of the transmission wheel 132, a section of the original bottom of the support belt 133 moves to the top of the support belt 133 to seal the bottom of the container box 134, and this section is also in contact with the liquid adhesive, so that it is convenient to rotate and bond with the inclined surface when it is used next time.

[0043] Among them, because the opening at the bottom end of the receiving box 134 slides against the supporting belt 133, only the side wall at the bottom end of the receiving box 134 acts as a scraper on the supporting belt 133, and only a thin layer of liquid adhesive is formed on the supporting belt 133, thereby avoiding the problem that the adhesion force between the supporting belt 133 and the inclined surface is too large, which may cause difficulty in moving the automatic photovoltaic panel lifting device away from the inclined surface.

[0044] Here, one of the driving wheels 132 is connected to a motor 135 to drive the support belt 133 to move. A feeding port is opened on the side wall of the receiving box 134, through which the liquid adhesive can be added to the receiving box 134. A sealing plug 136 is provided at the feeding port to form a sealed environment in the receiving box 134 to prevent the liquid adhesive from failing.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
