Detailed Description
The present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific examples described in the following embodiments of the present invention are merely illustrative of specific embodiments of the present invention and do not constitute limitations on the scope of the invention.
The invention is further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, wherein fig. 1 is a schematic structural diagram of a safety tool for high-pressure nuclear phase according to a preferred embodiment of the present invention.
The embodiment is a safety tool 1 for high-voltage phase checking, the safety tool 1 assists a phase checking device to check a phase of a high-voltage power distribution cabinet 2, the high-voltage power distribution cabinet 2 is provided with a rail wheel 21 and an insulating baffle 22 linked with the rail wheel 21, the insulating baffle 22 is used for separating an upper female seat and a lower female seat of a cabinet body of the high-voltage power distribution cabinet 2, and the upper female seat and the lower female seat are also objects of the phase checking; the rail wheel 21 is linked with the insulating baffle 22, when the rail wheel 21 is pushed to a certain position, the insulating baffle 22 is opened, and workers can check the upper female seat and the lower female seat; when the pushing force of the rail wheel 21 is removed, the insulation barrier 22 rebounds to the original position.
The safety tool 1 comprises a handle 11 and an opening card 12 connected with the handle 11. The rail wheel 21 is pushed by the opening card 12 until the insulating baffle 22 is opened, and the phase checking device carries out phase checking. With the aid of the opening card 12, the worker does not need to directly contact the rail wheel 21 with hands, so that the safety of the worker is guaranteed, the working strength is reduced, the complexity of operation is reduced, and the nuclear phase efficiency is improved.
Further, handle 11 is insulating handle, and insulating handle has the protectiveness more, avoids taking place unexpected electric shock accident. In this embodiment, the handle 11 is manually pushed, but in other embodiments, the handle 11 may be mechanically controlled.
Further, the shape of the opening card 12 matches the rail wheel 21. The function of the opening card 12 is to push the rail wheel 21 and fix the rail wheel, and the shape of the opening card 12 is matched with the rail wheel 21, so that the fixing effect is better.
Further, the inner edge of the opening card 12 is wave-shaped, toothed or arc-shaped. The inner edge of the opening card 12 can be designed accordingly according to the actual situation, so as to fix the rail wheel 21 as the standard.
Further, the opening angle of the opening card 12 is 20-40 degrees, the opening angle of the opening card 12 is matched with the rail wheel 21, and the opening is too large, so that the space is occupied; the openings are too small and the fixing effect is poor.
Furthermore, the opening angle of the opening card 12 is fixed, and the fixed opening angle enables the fixing effect to be better and is not easy to loose.
Further, the opening angle of the opening card 12 is adjustable, and the adjustable opening angle enables one safety tool 1 to be applied to the rail wheels 21 of various specifications, so that the use is more convenient.
