Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and more specifically, it relates to a photovoltaic support protection device. Background Technology

[0002] During the long-term operation of photovoltaic power generation systems, photovoltaic supports are subject to various external forces such as wind load, snow load, and foundation settlement. Especially under severe weather conditions, they are prone to tilting or collapse. Existing photovoltaic supports typically adopt a fixed design and lack effective auxiliary support methods. When the support columns are subjected to lateral forces or uneven settlement, they cannot provide additional stable support to distribute the load. This leads to deformation or instability of the overall support structure during long-term use, which not only affects the power generation efficiency and service life of the photovoltaic panels, but may also cause equipment damage and safety accidents, seriously threatening the stable operation of the photovoltaic power generation system and investment returns.

[0003] During the installation, commissioning, and maintenance of photovoltaic (PV) brackets, it is often necessary to precisely adjust the support height and angle according to the site terrain conditions and installation accuracy requirements to ensure that the PV panels achieve the best light-gathering angle and power generation effect. Traditional bracket adjustment methods usually use a fixed structure with welding or bolt connections. The adjustment process requires disassembling and reinstalling a large number of connectors, which is not only complicated and time-consuming, but also prone to loosening or falling off of the adjustment components under vibration and impact due to insecure connections, increasing the installation difficulty and maintenance costs.

[0006] The present invention is further configured such that each of the multiple sets of adjusting rods has an adjusting hole, and the multiple sets of sleeves have insertion holes. The insertion rod is inserted into the insertion rod and the adjusting hole, which facilitates flexible adjustment through the cooperation of the insertion rod and the adjusting hole, ensuring the adjustability and applicability of the device.

[0007] The present invention is further provided with an unlocking sleeve that slides on the outside of the card slot. The outer side of the unlocking sleeve is tapered, which provides a simple unlocking operation.

[0008] The present invention is further provided that the inner side of the multiple sets of card blocks and the bottom end of the insertion rod are provided with inclined surfaces. The design of the inclined surfaces helps the card blocks and the insertion rod to fit better, improves the stability of the connection, and ensures the reliable fixation of the insertion rod.

[0009] The present invention is further configured such that a guide groove is provided on the inner side of the card slot, the unlocking sleeve slides in the guide groove, and a compression spring is provided between the unlocking sleeve and the guide groove. The arrangement of the guide groove and the compression spring ensures that the unlocking sleeve slides smoothly, thereby improving the operational stability and comfort of the device.

[0010] The present invention is further configured such that a sliding rod is fixedly provided on the top surface of the unlocking sleeve, and the sliding rod is slidably connected to the insertion rod. The slidable connection between the sliding rod and the insertion rod enables more precise adjustment and improves the flexibility and accuracy of operation.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a photovoltaic support protection device, which has the following beneficial effects: 1. This device achieves stable reinforcement of the photovoltaic support structure through a support mechanism installed on the outside of the support column. The support mechanism adopts a telescopic structure with a fixed frame, multiple sets of sleeves and adjusting rods. The screw drives the support plate to support the ground and provide additional lateral support force to the support column. This effectively disperses the impact of external forces such as wind load, snow load and foundation settlement on the support structure, significantly improving the overturning resistance and overall stability of the photovoltaic support structure under severe weather conditions. It avoids deformation or instability caused by uneven stress on the support structure, ensuring the normal power generation efficiency and service life of the photovoltaic panels, and guaranteeing the stable operation and investment returns of the photovoltaic power generation system.

[0014] 2. The fixing mechanism of this device uses the insertion structure of the plug rod and the fixing sleeve, combined with the locking mechanism of the locking block and the locking groove, to achieve quick fixing of the adjusting rod at any position inside the sleeve. The operator only needs to align the adjusting hole with the plug hole and insert the plug rod to complete the automatic locking. There is no need to use welding or a large number of bolts to connect, which greatly simplifies the bracket adjustment process and shortens the installation and debugging time. At the same time, the elastic pressing action of the push spring ensures the firmness of the connection, effectively preventing the adjusting parts from loosening or falling off under vibration and impact, reducing the installation difficulty and maintenance cost.

[0015] 3. The tapered design of the unlocking sleeve in this device, combined with the beveled structure at the bottom of the locking block and the insertion rod, makes the unlocking process of the adjusting rod extremely convenient. The operator only needs to rotate the hexagonal sleeve to automatically complete the unlocking action of disengaging the locking block and pulling out the insertion rod through the transmission action of the thrust bearing and the sliding sleeve. This avoids the tedious operation of frequently disassembling and assembling connecting parts in traditional fixed structures, effectively reduces the wear and damage risk of connecting parts, extends the service life of the entire support system, improves the reliability and economic benefits of the equipment, and meets the actual needs of photovoltaic power generation systems for efficient maintenance and long-term stable operation.
