A survey device for a photovoltaic system

Abstract

The invention discloses a photovoltaic system installed capacity device, which comprises a solar power generation panel and a guide base, and is characterized by further comprising a tension adjustingmechanism, a unidirectional loose prevention mechanism moving along with the tension adjusting mechanism, a movable steering mechanism, a walking mechanism and a driving mechanism driving the walkingmechanism to move, wherein one side of the top of the guide base is provided with a protective cover, the tension adjusting mechanism arranged inside the protective cover comprises a hydraulic cylinder, a piston rod at the top of the hydraulic cylinder is provided with a lifting plate, the up and down movement of the piston rod drives the lifting plate to move steadily up and down, the top of thelifting plate is provided with two supports arranged side by side, a rotating rod is connected between the two supports, the middle part of the rotating rod is provided with two positioning circularplates which are arranged opposite to each other, and a photovoltaic system surveying cable wound on the rotating rod is arranged between the two positioning circular plates. The photovoltaic system installed capacity device performs photovoltaic system surveying conveniently and quickly, protects the surveying cable from being damaged, improves the service life of the cable, reduces the labor cost and guarantees the personal safety.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a survey device for a photovoltaic system. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. The key element of this technology is the solar cell. Solar cells can be packaged and protected after being connected in series to form a large-area solar cell module, and then cooperate with power controllers and other components to form a photovoltaic power generation device. The power generation capacity of this device is the installed capacity. [0003] When the photovoltaic installed capacity exceeds 25% of the transformer capacity, there will be frequency, voltage or overload operation, which will have an impact on the photovoltaic and grid side. If you leave it alone, it will cause the grid to collapse and direc...

Problems solved by technology

[0003] When the photovoltaic installed capacity exceeds 25% of the transformer capacity, there will be frequency, voltage or overload operation, which will have an impact on the photovoltaic and grid side. If you leave it alone, it will cause the grid to collapse and directly affect the user's safety. Electrical Equipment Safety

[0004] In the existing technology, photovoltaic power generation systems are generally installed on building roofs, grounds, hillsides, and waters, and some of them have huge areas. It is inconvenient to survey special areas. Generally, at least two people are required to coordinate together during surveys, which not only poses great personal safety hazards , while consuming a lot of manpower and material resources, there are great limitations in actual operation
