Detailed ways

Below in conjunction with the accompanying drawings, the present invention will be described in the form of embodiments to assist those skilled in the art to understand and implement the present invention. Unless otherwise specified, the following embodiments and technical terms therein should not be understood without departing from the background of technical knowledge in the technical field.

The electric energy meter maintenance device of the present invention, referring to FIGS. 1-4 , includes an electric energy meter homing module 2 , a detection terminal 72 for electrically connecting the electric energy meter maintenance device 7 , and a detection terminal driving mechanism (not shown).

The electric energy meter homing module 2 includes an inclined table 21 and an anti-slip stopper 22 , and the inclined table 21 and the anti-slip stopper 22 cooperate to support the electric energy meter 6 arranged on the inclined table 21 . Since the inclined table 21 is inclined, the anti-slip stopper 22 may be a rough surface on the inclined table 21, or may be a physical structure disposed on the lower side of the inclined table. In order to prevent the electric energy meter from sliding off the inclined platform 21 under the action of gravity. The upper surface of the inclined table 21 is preferably a smooth surface, so the anti-slip stopper 22 needs to be arranged on the lower side of the inclined table, so that the electric energy meter 6 placed on the inclined table 21 will slide to the bottom of the inclined table 21. The lowest position is supported by the anti-slip stopper 22 . Alternatively, the inclined table 21 can also be formed by a plurality of polished rods, and the axes of the polished rods are preferably parallel or perpendicular to the inclination direction of the inclined table 21 . That is to say, the upper surface of the inclined table 21 is not necessarily a complete surface, but may also be a support surface formed by contacting the electric energy meter line. The polished rod can also be formed by a sleeve rotatably connected to the fixed shaft, which can also reduce the resistance of the electric energy meter sliding on the inclined table.

Wherein, a detection terminal through hole is formed on the anti-falling stopper 22 . The through hole of the detection terminal is used to enable the detection terminal to be electrically connected to the connection terminal of the electric energy meter, and it can be any shape that meets the requirements, such as an opening hole and a notch.

Among them, when in use, the detection terminal has two working positions, which are the electrical connection position that is electrically connected to the terminal of the electric energy meter arranged on the inclined table 21, and the avoidance position that does not affect the transfer of the electric energy meter arranged on the inclined table 21. . Referring to FIG. 1, although the detection terminal is electrically connected to the connection terminal of the electric energy meter in the maintenance position provided on the inclined table 21, the electric energy meter can still be slid up obliquely. No need to move. However, when the electric energy meter is transferred from other places to the maintenance position on the inclined table, or when it is transferred from the maintenance position on the inclined table to other places, the detection terminal should be in a position that does not affect the maintenance position set on the inclined table. Avoidance position for energy meter transfer. When the detection terminal 72 is in the electrical connection position, it can be electrically connected to the connection terminal of the electric energy meter arranged on the inclined table 21 through the detection terminal perforation. When the detection terminal 72 is in the avoidance position, it does not affect the electric energy meter arranged on the inclined table. transfer.

Wherein, the detection terminal driving mechanism is used to drive the detection terminal 72 to move between the electrical connection position and the avoidance position. Referring to Fig. 1-4, the detection terminal moves linearly on the axis of the connection terminal of the electric energy meter in the maintenance position on the inclined table 21, that is to say, the detection terminal driving mechanism can be selected as a linear displacement mechanism, such as electric push rod, straight stroke Cylinder, screw mechanism, crank slider mechanism. The linear displacement mechanism includes a casing and a movable member. The movable member can move on a certain straight line relative to the casing, so that the movable straight line of the movable member is parallel to the axis of the connection terminal of the electric energy meter in the maintenance position on the inclined table 21, so that the detection The axis of the terminal and the axis of the connection terminal of the electric energy meter in the maintenance position on the inclined table 21 are fixedly connected to the housing and the fixed frame, and fixedly connected to the movable element and the detection terminal.

Fig. 3 shows a detection terminal unit of an electric energy meter maintenance equipment. The detection terminal unit includes a guide sleeve 71, a detection terminal 72 and a return spring 73. The detection terminal 72 is penetrated in the guide sleeve 71 and can be connected in the electrical connection position, avoid Generally, in the initial state, the detection terminal 72 is set in the avoidance position, and the detection terminal driving mechanism pushes the detection terminal 72 to move to the electrical connection position. The terminals are electrically connected, and the return spring 73 is in a stretched state at this time. It should be understood that the return spring 73 can drive the detection terminal 72 to reset from the electrical connection position to the avoidance position. Therefore, the return spring 73 belongs to a component of a detection terminal driving mechanism. In this detection terminal driving mechanism, the detection terminal driving mechanism There are other components to drive the detection terminal 72 to adjust from the avoidance position to the electrical connection position. It should be noted that if the detection terminal driving mechanism drives more than two detection terminals at the same time, the detection terminal driving mechanism should be insulated from the detection terminals to prevent these detection terminals from forming electrical paths through the detection terminal driving mechanism.
