Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a photovoltaic bracket. Background Art

[0002] Photovoltaic power generation system refers to a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. A typical solar photovoltaic power generation system consists of solar cell arrays (modules), cables, power electronic converters (inverters), energy storage devices (batteries), loads, or users, etc. The modules are installed on photovoltaic brackets, facing the sun, to convert solar energy into electrical energy, and the generated DC power is converted through inverters, and finally stored in batteries for subsequent use. Since the components are usually installed in areas with harsh geographical environments or complex climatic conditions such as deserts, coastal areas, polar regions, mountains, and wind outlets, in order to prevent the components from being damaged, the requirements for photovoltaic brackets that fix the components will be higher. Usually, metal brackets with a certain strength and conducive to fixing and supporting are used. For example, the prior art: CN219041697U, a photovoltaic bracket, including left and right vertical support rods, left and right oblique support rods, lateral connecting rods and transverse reinforcement rods, characterized in that the vertical support rods and the upper parts of the oblique support rods are rotatably connected, the lateral connecting rods are rotatably connected between the vertical support rods and the oblique support rods, the transverse reinforcement rods are rotatably connected between the left and right vertical support rods and between the left and right oblique support rods, the lateral connecting rods include a first connecting rod and a second connecting rod that are rotatably connected, and the transverse reinforcement rods include a first reinforcement rod and a second reinforcement rod that are rotatably connected.

[0003] There are other existing technologies:

[0004] CN219697522U, a photovoltaic support;

[0005] CN218771898U, a photovoltaic support;

[0006] The above-mentioned support frame of the prior art is firm and reliable, and can effectively reduce the possibility of damage to the components by the external environment. The disadvantage is that the entire frame cannot be adjusted to the angle with the ground. In actual use, due to the difference in longitude and latitude, the angle of direct sunlight in different regions will be different. The most important thing is that if it is built in an area with an angle between the ground and the horizontal plane, such as a slope, the fixed inclination angle of the bracket will cause the battery component to be incorrectly positioned at the angle with the sun, and the best solar energy absorption effect cannot be achieved.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1 , the utility model provides a technical solution: a photovoltaic bracket.

[0023] Among them, a rotating head 105 is fixedly connected to the left side of the bracket 1, and the rotating head 105 is arranged inside the support plate 2, a beam frame 4 is connected between the two support plates 2, and a beam frame 2 5 is arranged between the two brackets 1, a connecting frame 6 is connected to the right side of the support plate 2 near the bottom, a socket 601 is opened through the front of the connecting frame 6, and a pin is arranged inside the socket 601, a support frame 2 3 is arranged on the right side of the connecting frame 6, a connecting frame plug block 301 is fixedly connected to the left side of the support frame 2 3, a sliding shaft 302 is fixedly connected to the top of the support frame 2 3, a movable frame 9 is installed at the bottom of the bracket 1, and a sliding cavity 901 is opened through the front of the movable frame 9.

[0024] In this embodiment, there are two brackets 1, which are locked in the middle by a crossbeam frame 2 5. Similarly, there are two support frames 1 2, which are locked in the middle by a crossbeam frame 4. A through hole is opened on the front of the rotating head 105, and a rotating shaft is connected inside. The rotating shaft is fixed on the support frame 1 2. The width of the sliding cavity 901 is the same as that of the sliding shaft 302. The connecting frame plug block 301 can be inserted into the square hole in the middle of the connecting frame 6. At the same time, a hole with the same size and position as the plug hole 601 is also opened on the connecting frame plug block 301. The bottom surfaces of the support frame 2 3 and the support frame 1 2 are flush To adjust the distance between the support frame 2 3 and the connecting frame 6, the sliding shaft 302 slides in the sliding cavity 901, pulling the movable frame 9 and then pulling the bracket 1 to rotate, so that the bracket 1 connected to the rotating head 105 can rotate around the rotation axis to adjust the position of the bracket 1 and the ground. When adjusted to a suitable position, align the two holes on the socket 601 and the connecting frame plug block 301, insert the pin, and the distance between the support frame 2 3 and the connecting frame 6 can be fixed, thereby locking the distance between the support frame 1 2 and the support frame 2 3, and also locking the angle between the bracket and the ground.

[0025] Among them, the materials of the bracket 1, the support frame 1 2, the support frame 2 3, the beam frame 1 4, the beam frame 2 5 and the connecting frame 6 are all square steel pipes.

[0026] In this embodiment, the square tube is cheap and lighter than square steel. It is also easy to process and can be cut and installed internally.

[0027] Among them, a top block 101 is fixedly connected to the inside of the bracket 1 near the left side, a double-headed screw 104 is set on the right side of the top block 101, a knob 102 is sleeved on the outside of the double-headed screw 104 near the left side, and a movable stopper 103 is sleeved in the middle of the outside of the double-headed screw 104 near both sides.

[0028] In this embodiment, the top block 101 is provided at two locations, one is close to the right side of the rotating head 105, and the other is in the middle of the bracket 1 near the right side. A double-headed screw 104 is provided between the two top blocks 101. The thread directions of the two ends of the double-headed screw 104 are different, while the thread directions of the movable stops 103 engaged on the double-headed screw 104 are the same. Therefore, when the double-headed screw 104 rotates, the distance between the two movable stops 103 will shorten or increase as the rotation changes. At the same time, the knob 102 on the right side of the left top block 101 passes through the opening at the corresponding position of the bottom of the bracket 1, and a part of the knob 102 is exposed from the bracket 1, so that the operator can directly touch the knob 102. When the knob 102 is turned, the double-headed screw 104 rotates with it, and the distance between the movable stops 103 becomes smaller, thereby clamping the battery panel assembly between the movable stops 103.

[0029] Among them, an extension frame 7 is installed inside the bracket 1 and extends from the front. A fixed foot 8 is installed on the front of the extension frame 7. A limiting axis 701 is fixedly connected to the inside of the bracket 1 near the right side. A limiting groove 702 is penetrated through the top of the extension frame 7. A rotating shaft 703 is fixedly connected to the right side of the extension frame 7.

[0030] In this embodiment, when the bracket 1 is fixed, the extension frame 7 extends from the inside of the bracket 1, and the fixing feet 8 are placed on the ground. The extension frame 7 is fixed to the ground by driving ground nails into the fixing holes 1, so that the extension frame 7 plays an auxiliary supporting role.

[0031] Among them, the support frame 1 2 and the beam frame 1 4, the bracket 1 and the beam frame 2 5, and the support frame 1 2 and the connecting frame 6 are connected by fasteners.

[0032] In this embodiment, the two ends of the crossbeam frame 1 4, the crossbeam frame 2 5 and the connecting frame 6 are fixedly connected with connecting plates. Holes are punched in the connecting plates and fasteners are used to install them on the corresponding support frames and brackets 1 to fix the entire bracket 1 and improve stability.

[0033] Working principle: When the operator turns the knob 102, the double-headed screw 104 rotates accordingly, and the distance between the movable blocks 103 increases. The photovoltaic panel assembly is placed between the movable blocks 103. The knob 102 is turned in the opposite direction, and the distance between the movable blocks 103 decreases, thereby clamping the panel assembly between the movable blocks 103. The pin on the socket 601 is unplugged, and the distance between the support frame 23 and the connecting frame 6 is adjusted. The sliding shaft 302 slides in the sliding cavity 901, pulling the movable frame 9 and then pulling the bracket 1 to rotate, so that the connecting rotating head 10 The bracket 1 of 5 can be rotated around the axis to adjust the position of the bracket 1 and the ground. When adjusted to a suitable position, the two holes on the socket 601 and the connecting frame plug block 301 are aligned, and then the pin is inserted to fix the distance between the supporting frame 2 3 and the connecting frame 6, thereby locking the distance between the supporting frame 1 2 and the supporting frame 2 3, and also locking the angle between the bracket and the ground. Finally, the extension frame 7 extends from the inside of the bracket 1, and the fixing foot 8 is placed on the ground. By driving a ground nail into the fixing hole 1, the extension frame 7 is fixed to the ground, so that the extension frame 7 plays an auxiliary supporting role.
