Embodiment 1

[0033] Such as Figure 1 to Figure 3 As shown in the figure, a hoop device for preventing misoperation of the brake knife includes a hoop body 1 and an operating rod 2. The diameter of the operating rod 2 is adapted to the diameter of the operating hole 3.1 on the knife transmission shaft 3. The hoop body 1 It includes a cylindrical hoop 1.1, a square hoop 1.2, an elastic opening 1.3, an operation opening 1.4, a first fastening piece 1.5, and a second fastening piece 1.6. The square hoop 1.2 is fixed and connected with the cylindrical hoop 1.1. Enclosing a fixed cavity 1.7, the two ends of the fixed cavity 1.7 communicate with the outside world; the operation opening 1.4 is arranged on the position opposite to the outer wall of the cylindrical hoop 1.1 and the square hoop 1.2, and the diameter of the operation opening 1.4 is larger than the operation The diameter of the hole 3.1; the elastic opening 1.3 is arranged between the square hoop body 1.2 and the operation opening 1.4...

Embodiment 2

[0036] Such as Figure 4 and Figure 5 As shown, on the basis of Embodiment 1, the square hoop body 1.2 includes a first side wall 1.2.1 and two second side walls 1.2.2, and the two second side walls 1.2.2 are respectively connected to the first side The wall 1.2.1 is connected, the second side wall is connected with the cylindrical hoop body 1.1, the first side wall 1.2.1 is opposite to the operation opening 1.4, and the inner wall of the second side wall is provided with an elastic buckle 5, and the elastic protrusion The buckle 5 includes a base 5.1, a compression spring 5.2 and a telescoping head 5.3, the base 5.1 is fixed to the first side wall 1.2.1, the telescoping head 5.3 is slidingly connected to the base 5.1, one end of the compression spring 5.2 is in contact with the base 5.1, and the other end of the compression spring 5.2 Contact with telescoping head 5.3.

[0037] The side wall of the operating rod 2 is provided with a card hole 2.2, a chute 2.3 and an elasti...

Embodiment 3

[0040] On the basis of Example 2, a rubber sheet 1.8 is provided on the inner wall of the cylindrical hoop 1.1. The first fastening sheet 1.5 is provided with a first strip-shaped hole 1.5.1, and one side of the first strip-shaped hole 1.5.1 communicates with the outside world; the second fastening sheet 1.6 is provided with a second strip shaped hole 1.6.1, one side of the second strip-shaped hole 1.6.1 communicates with the outside world, the first strip-shaped hole 1.5.1 and the second strip-shaped hole 1.6.1 are set at opposite positions, and the fixing bolt 4 passes through the second strip-shaped hole 1.6.1 A strip of holes 1.5.1 and a second strip of holes 1.6.1. The strip-shaped hole can ensure that the fixing bolt 4 can still be installed within a certain installation error. At the same time, it is convenient to fix and take out the bolts.

Abstract

The invention discloses a hoop device and method for preventing knife switch misoperation. The hoop device comprises a hoop body and an operating rod, wherein the hoop body comprises a cylindrical hoop body, a square hoop body, an elastic opening, an operating hole, a first fastening piece and a second fastening piece. The square hoop body and the cylindrical hoop body are fixed and jointly definea fixing cavity. An operating aperture is formed in the position, opposite to the square hoop body, of the outer side wall of the cylindrical hoop body, and the diameter of the operating aperture islarger than that of an operating hole. The first fastening piece and the second fastening piece are fixed through a fixing bolt. The invention provides a hoop device and method for preventing knife switch misoperation. The hoop device is simple in structure of a dismounting tool and low in manufacturing cost. The dismounting method is simple; the reliability is high. The hoop device can be additionally arranged on an existing knife switch without replacing the existing knife switch, so that the transformation is convenient and the cost is low.

Description

technical field [0001] The invention relates to the technical field of power equipment maintenance tools, in particular to a hoop device and method for preventing misoperation of a switch knife. Background technique [0002] Anti-misoperation of substation has always been a common topic. From the past lessons, it is not difficult to find that many misoperations will bring danger to people, power grids, and equipment, and cause huge losses. For the current manual operation of the switch knife, the aperture of the operating handle is double-passed. During the operation, due to the different operating habits of different people, the operation of the grounding switch knife, from the perspective of the secondary auxiliary contact, can only be correct according to the regulations. After the direction is operated, the monitoring background can monitor the grounding, otherwise the information displayed on the monitoring background is still incorrect, and it shows that there is no g...
