Description

Technical Field

[0001] This utility model belongs to the field of mechanized laying technology of photovoltaic medium and high voltage cables, specifically involving an unmanned new energy vehicle for laying photovoltaic medium and high voltage cables in remote deserts. Background Technology

[0002] Photovoltaic power generation utilizes the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. The directly generated direct current (DC) is converted into alternating current (AC) by an inverter, and finally, after being connected in series and parallel through transformer substations to form a circuit, it is uniformly sent to the step-up substation. Transformer substations are typically connected by 35kV medium- and high-voltage cables. Individual cable reels have large diameters and weigh up to 10 tons. Currently, cranes and manual labor are commonly used for cable laying. Traditional construction methods are inefficient, pose significant safety risks to personnel, and result in a high rate of localized damage to the cable sheath due to mechanical operations, affecting finished product protection and subsequent operation and maintenance safety.

[0003] To address the issues of low efficiency and significant safety and quality hazards in the laying of medium and high voltage cables, this paper proposes an unmanned new energy vehicle for laying photovoltaic medium and high voltage cables in remote deserts. This vehicle enables safe and efficient laying of photovoltaic medium and high voltage cables, reduces the number of laying personnel, lowers the cable sheath damage rate, and achieves the goal of cost reduction and efficiency improvement.

It is powered by electricity, is environmentally friendly, and is equipped with an unmanned driving system for automatic driving within the site. It can operate simultaneously on multiple cable reels depending on the number of cables to be laid, enabling parallel construction on multiple work surfaces and solving the aforementioned technical problems.

[0005] An unmanned new energy vehicle for laying medium and high voltage photovoltaic cables in remote deserts includes three parts: a cable transport vehicle, a 360° rotating cable bracket, and a cable laying shock absorption system. The cable transport vehicle's cargo bed is equipped with a 360° rotating cable bracket, and a cable reel is located above the 360° rotating cable bracket.

The upper pressure roller base is a rotating support that can rotate 90° and remain parallel to the horizontal ground when not in operation. The electric roller base is a fixed support that can rotate actively, with the rotation speed matching the cable laying speed, and the cable is pressed back by a spring.

[0010] The aforementioned unmanned new energy vehicle for laying high-voltage photovoltaic cables in remote deserts comprises a 360° rotating cable bracket consisting of a vertical bearing, a power system, ball bearing grooves, and spherical balls.
