Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further described in detail by referring to the following embodiments.
The utility model provides an operating device for earthing switch. As shown in fig. 1 to 5, the operating mechanism of the earthing switch comprises a shutter 60, a position switch 20 of an electric controller and a detecting member 30.
The baffle 60 has an operation hole 601, and an operation handle 40 can be inserted from the operation hole 601 to manually operate the earthing switch located inside the baffle 60 through the operation shaft 50 of the earthing switch. That is, the operating handle 40 is connected to one end of the operating shaft 50 of the earthing switch inside the shutter 60 and manually operates the earthing switch located at the other end of the operating shaft 50. Referring to fig. 1 and 2, after the operating handle 40 extends from the operating hole 601, the operating shaft 50 of the grounding switch can be rotated, so as to open and close the grounding switch. The flap 60 can be located on the door of the switchgear cabinet. The size of the operation hole 601 can be matched with the operation handle 40. In addition, the operation handle 40 may be provided with an extension 401 as shown in fig. 1, and a recess (not shown) may be provided corresponding to the operation hole 601, so that the insertion direction of the operation handle 40 may be determined.
The position switch 20 of the electric controller is used to control the electric operation of the earthing switch. The position switch 20 of the electric controller can be a micro switch, and can also be any position switch of the existing electric controller. The position switch 20 can receive the position signal, and then the grounding switch is controlled to be switched off or switched on by the electric controller. The position switch 20 may be installed below the operation hole 601 and inside the shutter 60. Of course, the position of the position switch 20 can be set according to actual needs, and will not be described in detail herein. The position switch 20 has a button 201, and in the state that the button 201 is pressed, the electric operation of the grounding switch is locked, namely, the electric operation of the grounding switch can not be performed; in a state where the button 201 is not pressed, the electrical operation of the ground switch is unlocked, that is, the electrical operation of the ground switch can be performed. Specifically, it can be understood that, in a state where the button 201 is pressed, it cannot be executed without receiving a position signal or receiving a position signal; in a state where the button 201 is not pressed, it can normally receive the position signal and control the electric operation of the ground switch by the electric controller.
The sensing assembly 30 includes a first end and a second end of the linkage. In addition, the sensing assembly is capable of rotating about a fulcrum. During the process that the operating handle 40 extends into the operating hole 601, the operating handle 40 can push against the first end of the detecting component 30 to rotate the detecting component 30, and then the second end of the detecting component 30 can push against one button 201 of the position switch 20 and press the button 201. That is, the detecting member 30 can lock the electric operation of the earthing switch by rotating and pressing the position switch 20 by pushing of the operating handle 40. As shown in fig. 1, after the operating handle 40 is inserted into the operating hole 601, it pushes the first end of the detecting member 30, so that the detecting member 30 rotates counterclockwise, and the second end of the detecting member 30 can push the button 201 of the position switch 20 in the direction D, so that the button 201 is pressed.
Alternatively, to ensure that the electric controller is locked as quickly as possible, the detection assembly 30 may be located as close to the operation hole 601 as possible, so that the electric operation can be locked when the operation handle 40 is just inserted into the operation hole 601. The sensing assembly 30 may be the inside of the baffle 60 as shown in fig. 2. More specifically, the detection assembly 30 may be located above the position switch 20.
in the operating mechanism, the operating handle 40 pushes the detection assembly 30 to rotate so that the detection assembly 30 can press the position switch 20 in the process of being inserted into the operating hole 601, so that the locking of electric operation during manual operation of the grounding switch can be ensured, misoperation is avoided, and the personal safety of an operator is ensured.
as shown in fig. 1 to 5, the detecting assembly 30 may include a supporting member 301 and a lever 302, the lever 302 is pivotally connected to the supporting member 301, a first end of the lever 302 corresponds to the operation hole 601, and a second end corresponds to the elastic button 201. In such an implementation, the rotatable member is a lever 302. That is, the operating handle 40 can push against a first end of the lever 302, and a second end of the lever 302 can push against the button 201 of the position switch 20. More specifically, the first end has a projection 3021, such as the hook-shaped member shown in fig. 1, 4 and 5, the projection 3021 being for contacting the operating handle 40. As shown in fig. 4, the protruding portion 3021 can be seen from the operation hole 601 toward the inside of the baffle 60. This first end is thus accessible during insertion of the operating handle 40 into the operating hole 601. The end of the projection 3021 has a wedge shape a, the hypotenuse of which is used to contact the operating handle 40. Thus, the operation handle 40 can push the protrusion 3021 more smoothly.
The second end of the lever 302 has a contact plate 3022, the contact plate 3022 being adapted to push against the button 201. The contact plate 3022 has a large contact area, and reliability of the push button 201 can be ensured.
Optionally, the operating mechanism further includes a blocking body 10, the blocking body 10 has a first through hole 101 corresponding to the operating hole 601, the side of the blocking plate 60 facing the detecting assembly 30 has a second through hole 102, the second through hole 102 is communicated with the first through hole 101, and the protrusion 3021 extends from the second through hole 102 into the first through hole 101. The first through hole 101 corresponding to the operation hole 601 indicates that the operation handle 40 can protrude into the first through hole 101 through the operation hole 601. Thus, the operating handle 40 can push the protrusion 3021 of the lever 302 during the insertion. This first through-hole 101 can realize the limiting displacement to protruding portion 3021, and then guarantees that the second end of lever 302 accurately pushes away button 201.
The supporting member 301 may specifically include two opposite side plates 3011, each of the two side plates 3011 has a third through hole, the middle portion of the lever 302 has two protruding portions 3023 protruding toward the side plates 3011, and the protruding portions 3023 protrude into the corresponding third through holes. In this way, the lever 302 can be rotatably suspended on the support member 301. The structure and the process are simple, and the cost is low. In particular, the support member 301 may be fixed to a door of the switchgear.
In addition, the button 201 of the position switch 20 may be an elastic button. Thus, the button 201 is charged during the pressing process, and after the operating handle 40 moves out of the operating hole 601, the button 201 can release the energy to push against the second end, so that the detecting assembly 30 is reset. For example, after the operating handle 40 is moved out of the operating hole 601, the first end of the lever 302 is not pushed any more, and the second end is pushed by the push button 201, so that the detecting member 30 is reset. I.e. back to the position shown in fig. 4. Thus, the detecting assembly 30 can be automatically reset without an additional elastic member.
