Description

Complete ring main unit for secondary fusion Technical Field The application relates to the technical field of ring main units, in particular to a secondary fusion complete ring main unit. Background In an electric power distribution system, a secondary fusion complete ring main unit is used as key equipment, is widely applied to outdoor scenes, and bears important tasks of electric power distribution and control. The operational stability is directly related to the reliability of the regional power supply. However, long-term exposure of outdoor ring main units to the elements is challenging with many environmental factors, where rain effects are prominent. When the traditional ring main unit is used for coping with rainwater, an effective resource utilization means is lacked, so that not only is the water resource wasted, but also potential damage to equipment is caused due to rainwater accumulation. Therefore, development of the outdoor ring main unit with the rainwater recycling function becomes an important research direction for improving the environmental adaptability and the resource utilization efficiency of equipment. Currently, an outdoor ring main unit with a rainwater recycling function has appeared. The ring main unit consists of a box body and a box door arranged on the box body, and the bottom of the box body is fixed on a concrete base formed on the ground through screws. The top of the box body is provided with an upward bent water collecting eave, the inside of the base is provided with a water collecting cavity in advance, and the outside of the base is provided with a water intake pipe communicated with the water collecting cavity. Meanwhile, a water collecting pipe is arranged outside the box body, and the bottom of the water collecting eave is communicated with the water collecting cavity. In rainy days, rainwater is collected to the water collecting eaves, and rainwater passes through the water collecting pipe and gathers into the water collecting cavity. When the water in the water collecting cavity is needed to be reused, only the external water suction pipeline is connected with the water intake pipe, so that the rainwater can be recycled to a certain extent. Although the ring main unit structure can effectively realize the cyclic utilization of rainwater, the rainwater is directly collected into the water collecting cavity without any filtering or purifying treatment, and broken leaves, insects or other solid particles may be mixed in the ring main unit structure. After the impurities enter the water collecting cavity, the effective volume of the water collecting cavity can be occupied, and the available water quantity is reduced. When the rainwater is reused, the equipment contacted with the rainwater can be blocked, the normal operation of the equipment is influenced, the service life of the equipment is even shortened, and there is room for improvement. Disclosure of Invention The application aims to provide a secondary fusion complete ring main unit, which solves the problems that in the related art, although rainwater can be recycled by utilizing a water collecting cavity, corresponding external pipelines can be blocked in later use, and there is room for improvement. The application provides a secondary fusion complete ring main unit, which adopts the following technical scheme: A two-time fusion complete ring main unit comprises a box body and a box door arranged on the front side of the box body, wherein a plurality of radiating ports are formed in vertical surfaces on the left side and the right side of the box body, a base is fixedly arranged at the bottom of the box body, a rain guiding eave which is inclined downwards is arranged at the top of the box body, a rain collecting groove with an upward opening is formed in the periphery of the rain guiding eave, a water collecting cavity for rainwater injection and a connector communicated with the water collecting cavity are formed in the base, a filter box positioned on the left side and the right side of the box body is arranged on the upper side of the base, a flow guiding piece for injecting rainwater in the rain collecting groove into the water collecting cavity is arranged outside the box body, a connecting pipe for communicating the filter box and the water collecting cavity is arranged outside the box body, a cleaning port is formed in the upper side of the filter box, a cover plate for sealing the cleaning port is detachably arranged on the upper side of the filter box, and a filter screen is fixedly arranged on the end face of the connecting pipe, which is inserted into the filter box. Through adopting above-mentioned technical scheme, carry out preliminary filtration to the rainwater through the filter screen that the connecting pipe terminal surface set up in the rose box, effectively intercept solid particle impurity such as garrulous leaf, insect, avoid impurity direct water collecting cavity in the base stati
