Description

Technical Field

[0001] This utility model relates to the field of piston rod technology, specifically a corrosion-resistant piston rod for photovoltaic brackets. Background Technology

[0002] Solar photovoltaic (PV) brackets are specialized supports designed for placing, installing, and securing solar panels in a solar photovoltaic power generation system. They are typically made of aluminum alloy, carbon steel, or stainless steel. Solar support system products are primarily made of carbon steel and stainless steel, with the carbon steel surface undergoing hot-dip galvanizing for 30 years of outdoor use without rusting. When installing PV brackets in homes, shock-absorbing piston devices are often used for vibration damping, or piston-cylinder or hydraulic cylinders are used for position adjustment. Since PV brackets are commonly installed outdoors, the piston rods require corrosion-resistant treatment.

[0003] Existing piston rods are typically single metal rods that provide support during the movement of the telescopic piston. However, when used for supporting photovoltaic (PV) brackets, the piston rods are prone to corrosion due to their outdoor location and frequent exposure to extreme weather conditions such as high temperatures and heavy rain. Corrosion reduces the rod's telescopic activity, degrades its functionality, and results in relatively poor corrosion resistance and lubrication protection. This makes them ill-suited to adapt to varying working conditions and reduces their overall durability. Therefore, we propose a corrosion-resistant piston rod for PV brackets to address these issues.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 A corrosion-resistant piston rod for photovoltaic brackets includes a steel rigid inner rod 1 and an aluminum corrosion-resistant outer tube 2, wherein the aluminum corrosion-resistant outer tube 2 is wrapped around the outside of the steel rigid inner rod 1.

[0029] The outer side of the aluminum corrosion-resistant outer tube 2 is provided with a zinc-plated layer 3.

Multiple oil discharge holes 6 are evenly arranged in the inner ring of the oil storage ring 4. Rolling lubricating beads 7 are installed in each of the multiple oil discharge holes 6.

[0030] Multiple rolling lubricating beads 7 are evenly distributed in a ring shape on the outside of the aluminum corrosion-resistant outer tube 2;

[0031] The beneficial effects of this solution are as follows: By setting an aluminum corrosion-resistant outer tube 2 on the outside of the steel rigid inner rod 1, the aluminum corrosion-resistant outer tube 2 plays a role in corrosion resistance. The steel rigid inner rod 1 has good rigidity and load-bearing capacity, and has good rigidity, load-bearing capacity and corrosion resistance. The galvanized layer 3 improves the corrosion resistance of the rod. The inner side of the oil storage ring 4 is provided with a storage cavity 5 to store lubricating oil. The inner side of the oil storage ring 4 is provided with uniformly distributed oil outlet holes 6, and rolling lubricating beads 7 are installed inside. By rotating the rolling lubricating beads 7, the oil in the storage cavity 5 is discharged and the oil is lubricated to the aluminum corrosion-resistant outer tube 2 by the rolling lubricating beads 7, so that the rod is always kept with oil and always lubricated. The piston rod has good stability and durability, and the device has excellent corrosion resistance, is not easily affected by external erosion, and has excellent lubrication protection ability and good working tolerance.

[0032] Furthermore, the steel rigid inner rod 1 is a steel metal rod, and the aluminum corrosion-resistant outer tube 2 is an aluminum tube, which is sealed and wrapped around the outside of the steel rigid inner rod 1.

[0033] By setting the steel rigid inner rod 1 as a steel metal rod and the aluminum corrosion-resistant outer tube 2 as an aluminum tube, the aluminum corrosion-resistant outer tube 2 plays a role in corrosion resistance, and the steel rigid inner rod 1 has good rigidity and load-bearing capacity. When combined, they have both rigid load-bearing capacity and good corrosion resistance.

[0034] Furthermore, the zinc layer 3 is hot-dip galvanized onto the surface of the aluminum corrosion-resistant outer tube 2, and the rolling lubricating beads 7 are rolled and connected to the outside of the aluminum corrosion-resistant outer tube 2.

[0035] By setting a galvanized layer 3 to the surface of the aluminum corrosion-resistant outer tube 2, the surface corrosion resistance of the rod is further enhanced. During the rolling process, the rolling lubricating beads 7 can discharge the lubricant and lubricate the outside of the aluminum corrosion-resistant outer tube 2, which is practical.

[0036] Furthermore, an oil switch port 8 is provided on the outer ring of the oil storage ring 4, and a sealing plug 9 is filled in the oil switch port 8.

[0039] By setting the storage cavity 5 to store either oil-based lubricating oil or viscous lubricating oil, the lubricating oil can be freely adjusted or selected according to the usage and conditions of the rod. The rolling lubricating beads 7 are located at the bottom inside the oil storage ring 4, so that the rolling lubricating beads 7 can stably guide the lubricating oil out from the bottom, preventing insufficient lubricating oil and wear and idling of the rolling lubricating beads 7, which is practical.

The aluminum corrosion-resistant outer tube 2 plays a role in corrosion resistance. The steel rigid inner rod 1 has good rigidity and load-bearing capacity. When combined, it has both rigid load-bearing capacity and good corrosion resistance. The aluminum corrosion-resistant outer tube 2 is hot-dip galvanized with a zinc layer 3 on the outside, which further improves the corrosion resistance of the rod.

[0047] An oil storage ring 4 is provided on the outer side of the aluminum corrosion-resistant outer tube 2, and a storage cavity 5 is provided on the inner side of the oil storage ring 4. The storage cavity 5 can store lubricating oil.
