Description

Technical Field

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

[0002] Most existing mountain photovoltaic panels use fixed photovoltaic brackets to support photovoltaic panels, among which the most common is the plug-in photovoltaic bracket. The bracket uses a galvanized steel pipe with a steel cage welded at the tail as the lower column, which is integrally cast in a concrete micro-porous pile. The concrete micro-porous pile is rooted in the mountain ground. In order to adjust the height of the photovoltaic bracket, a galvanized steel pipe is inserted into the lower column as the upper column of the photovoltaic bracket. After installation, in order to prevent water from entering the steel pipe, a rubber ring is used to seal the interface between the two pipes.

[0003] However, in the actual installation process, due to deformation of the galvanized pipe mouth, damage to the rubber ring, mismatch of the rubber ring, etc., the rubber ring often cannot be installed, resulting in water entering the interface. After the water enters, there will be water accumulation at the bottom of the lower column, which can easily cause the lower column to rust. In addition, in areas with a large temperature difference between day and night, the accumulated water will continue to freeze and melt with the temperature change, which will cause the concrete micro-porous piles to rupture. The corroded bottom pipe and the ruptured micro-porous piles will cause the stiffness and strength of the photovoltaic bracket to fail to meet the wind pressure resistance requirements of the photovoltaic panel. Under the action of strong winds, the photovoltaic panel will collapse. Utility Model Content

[0007] Preferably, the support tail pipe and the steel cage are arranged on a common intermediate axis, and the support tail pipe forms a supporting cooperation with the bottom of the microporous pile through the steel cage.

[0008] As a more preferred embodiment, the upper section of the steel bars of the steel cage are welded to the lower section of the bracket tail pipe.

[0020] Embodiment 1 provides a self-draining photovoltaic bracket, which utilizes the characteristics of water as a self-flowing fluid, and processes a funnel-shaped drainage pipe 2 at the bottom of the bracket tail pipe 1. The water entering the bracket tail pipe 1 enters the conical portion 3 and is then discharged from the liquid outlet portion 4. The water entering the bracket tail pipe 1 is discharged without affecting the strength of the microporous pile 12, thereby avoiding water accumulation in the bottom pipe, thereby greatly reducing the probability of collapse of the photovoltaic panel 8;

[0021] During construction, place the above-mentioned bracket tail pipe 1 as a whole into the microporous pile 12, and pour concrete to the designed height. Be careful not to block the liquid outlet of the liquid outlet part 4 when pouring concrete. After the concrete is completely solidified, pull out the anti-clogging device 6 pre-installed in the liquid outlet. Subsequently, install the photovoltaic bracket according to the normal process.

[0022] As a preferred embodiment 2, the bracket tail pipe 1 and the steel cage 5 are arranged on the same intermediate axis, and the bracket tail pipe 1 forms a support fit with the bottom of the micro-porous pile 12 through the steel cage 5. This ensures the fixed installation of the bracket bottom and facilitates installation in the micro-porous pile 12.

[0023] As a preferred embodiment 3, the upper steel bars of the steel cage 5 are welded to the lower section of the bracket tail pipe 1 to ensure the stability and fixing strength of the installation.

[0024] As a preferred embodiment 4, the included angle between the middle axis of the conical portion 3 and the middle axis of the liquid outlet portion 4 is an obtuse angle, so as to ensure that the liquid outlet portion 4 is tilted downward so that the water flows out along the liquid outlet portion 4 by gravity.

[0025] As a preferred embodiment 5, the liquid outlet of the liquid outlet portion 4 passes through the steel cage 5 and then passes through the micro-porous pile 12. Ensure that the liquid outlet is exposed during cement pouring, so that self-drainage can be carried out by pulling out the anti-clogging device 6, and water flow is prevented from flowing out when the anti-clogging device 6 is installed.

[0026] As a preferred embodiment 6, the middle axis of the tapered portion 3 is coaxial with the middle axis of the bracket tail pipe 1, and the bottom end of the bracket tail pipe 1 is provided with an opening, and the opening of the tapered portion 3 is welded with the bottom end opening of the bracket tail pipe 1 to form a sealed connection, thereby ensuring the fixed installation of the funnel-shaped drain pipe 2.

[0027] As a preferred embodiment 7, the top of the bracket tail pipe 1 is sealed and connected with the upper column 7 through a rubber seal 11, and the upper section of the bracket tail pipe 1 is provided with a clamp 9, and the clamp 9 forms a limited fit with the photovoltaic panel 8 through a connecting rod 10. The normal installation of the subsequent photovoltaic panel 8 and the bracket components is ensured.

[0028] The working principle of this utility model:

[0029] The utility model provides a self-draining photovoltaic bracket, which utilizes the characteristics of water as a self-flowing fluid, and processes a funnel-shaped drainage pipe 2 at the bottom of the bracket tail pipe 1. The water entering the bracket tail pipe 1 enters the conical part 3 and is collected and then discharged from the liquid outlet 4. The water entering the bracket tail pipe 1 is discharged without affecting the strength of the micro-porous pile 12, thereby avoiding water accumulation in the bottom pipe, thereby greatly reducing the probability of collapse of the photovoltaic panel 8;

[0030] During construction, the above-mentioned bracket tail pipe 1 is placed as a whole in the micro-porous pile 12, and concrete is poured to the designed height. When pouring concrete, it is important not to block the liquid outlet of the liquid outlet 4. After the concrete is completely solidified, the pre-installed anti-clogging device 6 in the liquid outlet is pulled out. Subsequently, the photovoltaic bracket can be installed according to the normal process;

[0031] After the photovoltaic bracket is installed, if the seal between the upper and lower columns of the bracket is damaged, when it rains, rainwater will enter the inner cavity of the lower column from the gap between the upper and lower columns. Due to the drainage effect of the funnel-shaped drain pipe 2, the rainwater will be discharged along the funnel-shaped drain pipe 2, so that the rigidity and strength of the photovoltaic bracket column will not be affected by corrosion due to accumulated water.
