Detailed Embodiments

[0021] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0022] Embodiment 1

[0023] Referring to Figure 1 and Figure 2 As shown, a photovoltaic bracket with a counterweight of the present utility model includes: a support rod 2, and a plurality of the support rods 2 are connected by a connecting rod 22; a counterweight 1, a plurality of the counterweights 1 are provided, and the counterweight 1 includes a receiving cavity, the counterweight 1 is provided with a connection head communicating with the receiving cavity, and a pipe 11 is connected between the connection heads of adjacent counterweights 1, and the connecting rod 22 penetrates through the counterweight 1.

[0024] For a photovoltaic bracket with a counterweight in this embodiment, one end of the support rod 2 is used to connect with a photovoltaic panel 5, and the other end is used to connect with a roof. When encountering extremely strong wind weather, by injecting liquid into the receiving cavity of the counterweight 1, the weight of the counterweight 1 is increased. Since the connecting rod 22 penetrates through the counterweight 1, the overall weight of the photovoltaic bracket is increased, improving the anti-overturning ability of the photovoltaic bracket. After the extremely strong wind weather, the liquid in the receiving cavity is discharged, so that the house does not need to be under high load for a long time. And by providing a plurality of counterweights 1, the weight distribution on the roof is made uniform, and the stability of the photovoltaic bracket is also improved.

[0025] The photovoltaic bracket with a counterweight further includes a fixing base 21, the fixing base 21 is located on a bottom plate 4, and the bottom plate 4 can be regarded as a roof. The fixing base 21 can be regarded as a concrete casting. The bottom end of the support rod 2 is connected to the fixing base 21. Preferably, a first connecting member 25 is provided in the fixing base 21, the first connecting member 25 is U-shaped, the connecting ends of the first connecting member 25 extend out of the top of the fixing base 21, a connecting plate is further provided on the top of the fixing base 21, the connecting ends of the first connecting member 25 penetrate through the connecting plate, and the outer side walls of the connecting ends of the first connecting member 25 are connected to the connecting plate. The end of the support rod 2 is connected to the connecting end of the first connecting member 25 by bolts, so that the support rod 2 is stably connected to the fixing base 21.

[0026] The counterweight 1 is placed on the bottom plate 4. The counterweight 1 includes a receiving cavity for receiving liquid. The counterweight 1 is provided with a connector communicating with the receiving cavity. The connector includes a first connector 12 and a second connector 13. The first connector 12 is located at the top of the counterweight 1, and the second connector 13 is located on the side wall of the counterweight 1 close to the support rod 2 and at a position close to the bottom. The counterweight 1 can inject liquid into the receiving cavity through both the first connector 12 and the second connector 13. For example, water can be injected into the receiving cavity to increase the weight of the counterweight 1. A pipeline 11 is connected between the connectors of adjacent counterweights 1, and the pipeline 11 is connected to the second connector 13, so that the receiving cavities of multiple counterweights 1 are communicated. By injecting liquid into one of the counterweights 1 through the first connector 12, the liquid can flow into the receiving cavities of each counterweight 1 through the pipeline 11, so that multiple counterweights 1 can be injected with liquid at the same time, and the liquid weights in each counterweight 1 are the same.

[0027] The counterweight 1 is located between adjacent support rods 2, and the number of counterweights 1 between any two support rods 2 in a single direction is equal. Specifically, referring to Figure 3 As shown, in this embodiment, the counterweights 1 and the support rods 2 are alternately arranged longitudinally, so that the distribution of the counterweights 1 on the bottom plate 4 is more uniform, improving the stability of the photovoltaic support. In another embodiment, the counterweights 1 and the support rods 2 are alternately arranged transversely. In another embodiment, the counterweights 1 and the support rods 2 are alternately arranged both transversely and longitudinally. In another embodiment, at least two counterweights 1 are provided between adjacent support rods 2, so as to increase the weight limit of the photovoltaic support. The pipeline 11 passes through the fixing seat 21, so that the counterweights 1 on both sides of the fixing seat 21 are communicated.

[0028] A connecting rod 22 is connected between the support rods 2. The support rod 2 is perpendicular to the bottom plate 4, and the connecting rod 22 is perpendicularly connected to the support rod 2. The setting of the connecting rod 22 makes the support rod 2 more stable. The connecting rod 22 passes through the counterweight 1. Specifically, the counterweight 1 is provided with a passage for the connecting rod 22 to pass through, and the passage is not communicated with the receiving cavity, so that after the liquid is injected into the counterweight 1, the connecting rod 22 can be pressed, thereby increasing the overall weight of the photovoltaic support, improving the stability and anti-overturning ability of the photovoltaic support. In another embodiment, a connecting rod 22 is also connected between the fixing seats 21, and the connecting rod 22 is connected to a position close to the bottom of the side wall of the fixing seat 21. A groove is provided at the bottom of the counterweight 1, and the connecting rod 22 is located in the groove so that the connecting rod 22 passes through the counterweight 1.

[0029] The photovoltaic support with a counterweight further includes a mounting plate 23, which is connected to the end of the support rod 2. The mounting plate 23 is used for mounting the photovoltaic panel 5. Specifically, the mounting plate 23 is connected to the top end of the support rod 2, and the plane where the mounting plate 23 is located forms an acute angle with the plane where the bottom plate 4 is located. A second connecting member 24 is connected to the side of the mounting plate 23 close to the support rod 2, and the end of the support rod 2 is hinged to the second connecting member 24, so that the angle of the mounting plate 23 can be finely adjusted. After the fine adjustment is completed, the support rod 2 and the second connecting member 24 are fixedly connected by bolts, so that the mounting plate 23 is fixed. A top rod 3 is also connected between the mounting plate 23 and the support rod 2. One end of the top rod 3 is hinged to the mounting plate 23 through a third connecting member 31, and the other end of the top rod 3 is hinged to the support rod 2 through a fourth connecting member 32. The third connecting member 31 is located between two adjacent second connecting members 24 on the mounting plate 23, and the fourth connecting member 32 is located at the middle position of the support rod 2, so that the connecting rod 22 can move with the position of the mounting plate 23. The connecting rod 22 can be fixedly connected to the third connecting member 31 and the fourth connecting member 32 by bolts. The setting of the connecting rod 22 makes the overall strength of the photovoltaic support higher.

[0030] When encountering extremely strong wind weather, liquid is injected into the accommodating cavity through the first joint 12 of the counterweight 1. The liquid flows through the pipeline 11 to the adjacent counterweight 1 until it flows to all the counterweights 1. The liquid in all the counterweights 1 increases simultaneously until the liquid level reaches the specified position. After the extremely strong wind weather passes, the second joint 13 of the counterweight 1 close to the edge of the bottom plate 4 is opened, so that all the liquid in the counterweights 1 flows out, thus completing the liquid discharge. At the same time, injecting liquid into the accommodating cavity through the first joints 12 of multiple counterweights 1 can improve the liquid injection efficiency, and discharging liquid through the second joints 13 of multiple counterweights 1 can improve the liquid discharge efficiency.

[0031] Embodiment 2

[0032] The present utility model also provides a photovoltaic module, which includes the photovoltaic support with a counterweight in Embodiment 1, and further includes a photovoltaic panel 5. The photovoltaic panel 5 is connected to the mounting plate 23 of the photovoltaic support. Preferably, a spacer 51 is provided between the photovoltaic panel 5 and the photovoltaic support, so that there is a certain distance between the photovoltaic panel 5 and the mounting plate 23, thereby improving the heat dissipation effect of the photovoltaic panel 5.

[0033] The utility model discloses a photovoltaic support and photovoltaic assembly with a counterweight, wherein a plurality of counterweights 1 capable of applying pressure to a connecting rod 22 are provided. When encountering extreme weather, the overall weight of the photovoltaic support is increased by injecting liquid into the counterweight 1, thereby improving the anti-overturning ability of the photovoltaic support. After the extreme weather passes, the liquid is discharged, so that the house does not need to be under high load for a long time. Since the weight of the counterweight 1 can be adjusted, the photovoltaic support with a counterweight does not need to have its own counterweight, thereby facilitating installation while also reducing the load of the house at ordinary times, and flexibly adjusting the weight of the counterweight 1 under different circumstances. By equidistantly arranging a plurality of counterweights 1, the weight distribution of the roof is uniform, and the stability of the photovoltaic support is also improved. Adjacent counterweights 1 are connected by pipes 11, so that liquid can flow into the accommodating cavity of each counterweight 1 through the pipes 11, so that a plurality of counterweights 1 can be injected with liquid at the same time, and the weight of the liquid in each counterweight 1 is the same.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
