Description

Technical Field

[0001] The utility model relates to the technical field of nuclear power, in particular to a horizontal charging device for a nuclear power plant robot. Background Art

[0002] In some work areas within a nuclear power plant, due to the large number of pipelines, it is not very convenient for staff to conduct inspections. They often use nuclear power plant inspection robots for inspections. Nuclear power plant inspection robots require charging piles for charging. The charging piles of related technologies usually include two left and right charging plates and a sensing plate arranged between the two charging plates. When the charging interface of the nuclear power plant inspection robot presses the sensing plate, the charging plates on the left and right sides are powered on and charging can begin. However, if this structure deviates from the normal position of the nuclear power plant inspection robot, the middle contact plate may also be pressed down, causing the charging plates on the left and right sides to be abnormally charged, resulting in abnormal charging. In addition, the charging plate and the sensing plate of the charging pile mostly adopt a flat plate structure, and there is a situation where the charging interface and the charging plate and / or the sensing plate are unstable, affecting the charging effect.

Preferably, the first ends of the first mounting plate 31, the second mounting plate 61, the third mounting plate 41 and the fourth mounting plate 51 are connected to the mounting platform 20 by a rotating shaft 70 (such as Figure 5 The first mounting plate 31 is rotatably mounted on the mounting platform 20 (as shown).
