Detailed description of the invention
Below with reference to Figure of description and specific embodiment, this utility model is described in further details.
Fig. 1 to Fig. 6 show this utility model for single-column both arms vertical-telescopic disconnecting switch combined floodgate dead point instruction device a kind of embodiment, this instruction device includes dynamic instruction parts 1 and quiet instruction parts 2, dynamic instruction parts 1 are installed on the drive flange 3 of disconnecting switch and can be with drive flange 3 synchronous axial system, the transmission case 4 that dynamic instruction parts 1 are positioned at disconnecting switch is outside, quiet instruction parts 2 are installed on transmission case 4, when active connecting lever 5 contacts with caging bolt 6 and to be positioned at dead-centre position, dynamic instruction parts 1 turn to and the contact position of quiet instruction parts 2.In this structure, instruction device of the present utility model can be assembled into only with external dynamic instruction parts 1 and quiet instruction parts 2, its simple in construction, easy for installation, in disconnecting switch making process, active connecting lever 5 dead point the most excessively that can be pointed to the most intuitively in sealed transmission case is made and clearly being judged, be conducive to analyzing further and detection and isolation switchs whether in-place closing, it is to avoid due to the equipment caused not in place and the personal safety accident of closing a floodgate.
In the present embodiment, dynamic instruction parts 1 include anchor ear 11 and dynamic indicating arm 12, dynamic indicating arm 12 is affixed with anchor ear 11 outer wall, and anchor ear 11 hoop is located on drive flange 3, and anchor ear 11 is with drive flange 3 synchronous axial system and drives dynamic indicating arm 12 to turn to and the contact position of quiet instruction parts 2.During disconnecting switch moves to "on" position from gate-dividing state, dynamic indicating arm 12 remains and actively connecting lever 5 synchronizes to rotate clockwise, when active connecting lever 5 turns to combined floodgate dead-centre position, disconnecting switch feed motion completes, but "on" position keeps and contact clamping force needed dead point to ensure, so actively connecting lever 5 may proceed to turn an angle, until encountering combined floodgate caging bolt 6, whole making process completes.Now, dynamic indicating arm 12 is just struck against quiet instruction parts 2.As long as so dynamic indicating arm 12 is kept at an angle with actively connecting lever 5 and is synchronized with the movement, such that it is able to directly observe the position relationship between dynamic indicating arm 12 and quiet instruction parts 2 from outside, analyze detection and isolation and switch dead point of whether closing a floodgate.
In the present embodiment, anchor ear 11 is provided with opening, and opening part is provided with tension boss 111, turnbuckle 13 threaded on tension boss 111.So arrange, on the one hand ensure that the adjustability of anchor ear 11, it can be ensured that dynamic indicating arm 12 is kept at an angle with actively connecting lever 5 and is synchronized with the movement；On the other hand ensure that the detachability of anchor ear 11, it is simple to dismantle and change.
In the present embodiment, quiet instruction parts 2 include quiet indicating arm 21 and fastening bolt 22, quiet indicating arm 21 is installed on transmission case 4 by fastening bolt 22, when active connecting lever 5 contacts with caging bolt 6 and to be positioned at dead-centre position, dynamic instruction parts 1 turn to and the contact position of quiet indicating arm 21, its simple in construction, are easily achieved.
In the present embodiment, quiet indicating arm 21 is installed on the sidewall of transmission case 4 by fastening bolt 22.So arranging, quiet indicating arm 21 can vertically stretch to bottom transmission case 4, is beneficial to and the contacting of dynamic indicating arm 12.
In the present embodiment, quiet indicating arm 21 is installed on transmission case 4 on the sidewall installing caging bolt 6 and near caging bolt 6.So arrange, it is ensured that dynamic indicating arm 12 reaches unanimity with actively connecting lever 5, the rotary state of active connecting lever 5 is reflected into dynamic indicating arm 12 well, further increases intuitive.
Although this utility model discloses as above with preferred embodiment, but is not limited to this utility model.Any those of ordinary skill in the art, in the case of without departing from technical solutions of the utility model scope, technical solutions of the utility model are made many possible variations and modification by the technology contents that all may utilize the disclosure above, or are revised as the Equivalent embodiments of equivalent variations.Therefore, every content without departing from technical solutions of the utility model, according to this utility model technical spirit to any simple modification made for any of the above embodiments, equivalent variations and modification, all should fall in the range of technical solutions of the utility model are protected.
