Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to a power transmission system based on photovoltaic power generation with complementary fishery and photovoltaic power generation. Background Art

[0002] With the advancement of the concept of green and low-carbon energy development, photovoltaic power generation, as an important pillar of national green energy construction, plays a key role in optimizing the power energy structure. Photovoltaic power generation requires a large area of ​​ground or roof for the placement of power generation equipment. However, with the development of projects in recent years, the quality plots available for power station construction have become increasingly scarce, and the concept of complementary power generation between fishery and photovoltaic power generation has emerged.

[0003] Fishery-solar complementarity refers to the combination of fish farming and photovoltaic power generation. By setting up a photovoltaic panel array above the surface of the fish pond, a new model of "generating electricity above and raising fish below" is realized. This model not only makes full use of water resources and provides a good shelter environment for fish and shrimp farming, but also solves the problem of land shortage for photovoltaic power generation to a certain extent.

[0004] At present, fishery photovoltaic power generation projects are often built in remote offshore shallows, inland lakes and fish ponds, and require the construction of long-distance high-voltage power transmission line systems. At the same time, for the southern hilly areas, there are complex topography, undulating terrain, soft soil, etc., especially in areas near water bodies, the natural foundation conditions are poor, often accompanied by water and silt, making equipment installation difficult, and it is easy for equipment to be damaged by natural disasters such as lightning strikes, mud and rock flows, floods, and landslides. In particular, the problem of electric poles being prone to tilt and collapse has brought a series of problems to the promotion of fishery photovoltaic power generation projects.

[0005] In order to effectively protect the electric poles and reduce the losses caused by their collapse, the Chinese invention patent application with publication number CN112985501A discloses a multi-sensor electric pole disaster prevention and mitigation device and method, which includes a microwave radar level sensor, a level sensor, a three-dimensional sensor, a temperature and humidity sensor, a wind speed sensor, a comprehensive processing module, a data output device and a cloud warning platform. The current risk level of the electric pole is predicted by real-time monitoring of the flood level, the degree of collapse of the electric pole, the wind speed data, and the environmental temperature and humidity data, providing strong protection for the regular operation of electricity and the personal safety of local people. However, the above-mentioned device and method can only remotely understand the status of the electric pole. When the electric pole tilts and collapses, the management personnel of the control center need to notify the power maintenance personnel to go to the location of the electric pole for processing after receiving the reminder, which takes a long time, and before making a decision and arriving at the location of the electric pole, the condition of the electric pole can only be allowed to deteriorate over time.

[0039] When the present invention is in use, the gyroscope 6 monitors the angle of the electric pole 4 in real time. When the gyroscope 6 senses that the electric pole 4 is tilted, the controller 5 will send a signal to the cloud data monitoring platform 7, so that the power management personnel can find problems with the electric pole 4 in time. At the same time, the controller 5 controls the sound and light alarm 12 to sound an alarm and according to the tilt angle sensed by the gyroscope 6, according to the preset standard, the hydraulic cylinder 901 drives the cross arm 11 to slide to a suitable position along the strip sliding mouth 404 toward the direction close to the base 10, and when the power management personnel receive the reminder, they can remotely start the locker 801 through the controller 5, wait for the pull rope 803 to be loosened, start the winch 804, drive the pull rope 803 to be wound around the winch 804, and pull the electric pole 4 to reset or keep it stable.
