Problems solved by technology

[0002] Existing mobile power boxes are usually equipped with a roller structure, and the pull rod is used to drive the whole box to move. Since the power jack is provided, it is suitable for power maintenance and construction operations, especially for construction and maintenance sites with relatively harsh conditions. When in use, it is easy to be damaged, and in bad weather, the exposed power port is easy to cause safety hazards due to moisture

Embodiment 1

[0025] In this embodiment, in order to facilitate the movement of the end cover, preferably, a card slot 116 is provided on the lower end surface of the mounting plate 108, and the upper end surface of the housing 101 is provided with a position corresponding to the card slot 116. Corresponding to the positioning groove 117, the mounting plate 108 is provided with two through holes communicating with the card groove 116, and the mounting plate 108 is provided with a handrail 118, and both ends of the handrail 118 Bend to the same side and penetrate through the corresponding through holes to form a U-shaped structure. The two ends of the opening side are respectively inserted into the two through holes on the mounting plate. The end of the armrest 118 is provided with The pressing rod 119 connects the two ends of the opening side of the armrest, and enables the pressing rod to be embedded inside the positioning groove, and the pressing rod 119 can be inserted into the inside of t...

Embodiment 2

[0028] In order to make the bottom plate relatively fixed on the inner side of the stepped groove and keep the end cover stable, in this embodiment, preferably, a counter groove 125 is provided on the inner end surface of the stepped groove 110, and the length direction of the counter groove is parallel to the rotating shaft. In the axial direction of the sink groove, the sink groove opens to one side of the bottom plate. Two rubber pads 126 are provided on the opening side of the sink groove 125. The rubber pads are respectively symmetrically arranged on the two end surfaces of the sink groove opening side to form a strip structure. Two flanges 127 are provided at one end of the bottom plate 109 away from the end cover 106, and the flanges 127 can be clamped inside the sink groove 125.

[0029] When the end cover is attached to the shell, the flange on the bottom plate is clamped to the inside of the sink groove, and the rubber pad is used to prevent the flange from moving relati...

Embodiment 3

[0031] In this embodiment, in order to facilitate the easy rotation of the end cover to expose the operation panel after the boss is moved out of the through groove, preferably, a torsion spring 120 is provided on the rotating shaft 111, and the two torsion springs The ends are respectively fixedly connected to the rotating shaft, the middle of the torsion spring 120 abuts on the bottom plate 109, and the torsion spring 120 assumes the maximum torsion angle state when the boss 107 is embedded inside the through groove . When the boss is moved out of the through groove, the mounting plate is separated from the upper end surface of the shell. At this time, under the elastic force of the torsion spring, the end cover rotates relatively to make the end cover move to the outside quickly. The opening of the trough allows you to easily and intuitively see the operation panel.

[0032] Under the elastic force of the torsion spring, when the end cover is rotated to the outside, the end c...

Abstract

The present invention discloses a mobile maintenance power source box for a power grid. The mobile maintenance power source box comprises a shell and a charging box body arranged in the shell; two end surfaces of the charging box body, which face each other, are respectively provided with operation panels; one side of the shell is provided with a telescopic pull rod; two through slots are formed in the shell; the through slots are respectively corresponding to the operation panels; the inner sides of the through slots are provided with baffles; the outer side of the shell is provided with end covers; bosses which can be embedded into the through slots are formed at the middle portions of the end covers; the upper end surfaces of the end covers are provided with installation plates; the lower end surfaces of the end covers are provided with bottom plates; the lower end surface of the shell is provided with stepped grooves; and the inner sides of the stepped grooves are provided with rotation shafts. According to the mobile maintenance power source box for the power grid of the invention adopted, the charging box body is arranged at the inner side of the shell, so that the charging box body can be protected. The mobile maintenance power source box is especially suitable for being applied to electric power construction or maintenance processes.

Description

Technical field [0001] The invention relates to a special mobile maintenance power box for power grids. Background technique [0002] The existing mobile power box is usually equipped with a roller structure, and the whole box is driven by a tie rod to move. Because of the power jack position, it is used for power maintenance and construction operations, especially for construction and maintenance sites with poor conditions. When in use, it is easy to be damaged, and in bad weather, the exposed power port is likely to cause safety hazards due to moisture. Summary of the invention [0003] The purpose of the present invention is to provide a special mobile maintenance power box for power grids, which can protect the charging box body by placing the charging box body inside the shell, and is particularly suitable for use in electric power construction or maintenance processes. [0004] The present invention is realized through the following technical solutions: [0005] A special mobi...
