Description

Exposed cable protection device Technical Field The utility model relates to the technical field of new energy power generation equipment, in particular to an exposed cable protection device. Background In a photovoltaic power generation system, an inverter is an important device for converting direct current generated by a solar panel into alternating current. The bottom of the inverter case is typically provided with a plug for electrical connection with an external cable. These plugs need to maintain a stable and reliable connection during normal use, while also taking into account convenience during later maintenance. At present, the protection of the inverter plug mainly adopts the following modes: One is to directly expose the plug to the bottom of the inverter case, and only rely on the protection level of the plug itself to resist the influence of the external environment. The mode is simple in structure, but the plug is easily influenced by factors such as rainwater, dust and the like when being exposed to the external environment for a long time, so that the reliability of connection is reduced. Meanwhile, due to the lack of effective management of the connection cable, maintenance often encounters problems of too long or too short cables. Another is to add a simple protective cover on the outside of the plug. Although the protection level of the plug is improved to a certain extent, the protection cover can only cover the plug body, and the problem of cable management cannot be solved. Especially in the maintenance process, if the plug is required to be replaced or the cable length is required to be adjusted, the rewiring is often required, the operation is complex, and the cable is easy to damage.
