Description

Technical Field

[0001] This utility model belongs to the field of disconnecting switch technology, specifically a disconnecting switch driving structure. Background Technology

[0002] The main function of a disconnecting switch is to reliably isolate the equipment that needs maintenance from the live parts, forming a clear disconnection point to ensure the safety of maintenance personnel. In order to ensure safety during use, the conductive arm needs to be able to smoothly maintain connection or disconnection.

[0003] Meanwhile, a disconnector drive structure with application number CN202323334065.3 includes a support frame, a fixed platform on the upper surface of the support frame, and the fixed platform is welded and fixed to the support frame. Insulators are installed on both sides of the upper surface of the fixed platform. It also includes: a rotating seat, which is fixedly installed on the upper surface of the insulators. One of the rotating seats has a first contact installed inside, with a fixing member integrally formed at one end. The other rotating seat has a second contact installed inside. A drive mechanism is fixedly disposed at the front end of the other rotating seat and is fixed to both the rotating seat and the fixed platform. A worm gear is rotatably installed on the upper end of the drive mechanism, and the shaft at one end of the worm gear is fixed to the second contact. This disconnector not only achieves convenient adjustment while ensuring a secure connection between the two contacts.

[0004] However, the following problems were found in the implementation of the relevant technology: Although the existing device can maintain the connection or disconnection smoothly, once the main structure driving the lifting and lowering of the conductive arm is damaged, the conductive arm cannot be manually raised or lowered. The conductive arm can only be raised or lowered after the main structure is maintained, which affects the progress of subsequent work. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a disconnecting switch drive structure, which has the advantage that even after the electric telescopic rod that drives the lifting and lowering of the conductive arm is damaged, the lifting and lowering of the conductive arm can still be driven by manually controlling the lifting and lowering of the connecting rod, thus providing multiple ways to control the conductive arm and avoid affecting the progress of subsequent work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a disconnecting switch driving structure, including a base frame and two insulators mounted side by side on the top of the base frame. A main conductive base and a stationary contact base are respectively mounted on the top of the two insulators. A conductive arm is movably mounted on the inner side of the main conductive base. An electric telescopic rod and a connecting cylinder are also mounted on the top of the base frame. A connecting rod is movably inserted into the inner side of the connecting cylinder, and a first support frame supporting the bottom of the conductive arm is connected to the top of the connecting rod. A push plate is connected to the bottom of one side of the connecting rod, and a strip groove for accommodating the push plate is constructed on one side of the connecting cylinder. Corresponding fixing holes are opened between corresponding sides of the connecting rod and the connecting cylinder, and fixing rods are inserted between the corresponding fixing holes. A circular handheld component is connected to the side of the fixing rod away from the connecting rod.

[0007] Preferably, the top of the output end of the electric telescopic rod is connected to a second support frame, and the second support frame is supported on the corresponding side of the bottom of the conductive arm.

[0008] Preferably, rubber pads are adhered to the inner bottom of both the first support frame and the second support frame, and the rubber pads are supported on the corresponding side of the bottom of the conductive arm.

[0009] Preferably, the side wall of the electric telescopic rod is fixedly fitted with a fixing seat, and multiple fixing screws are screwed in a ring shape between the fixing seat and the top of the base frame.

[0010] Preferably, the bottom of both sides of the symmetrical base frame are connected to a reinforcing plate, and the top of the reinforcing plate is provided with multiple reinforcing holes arranged in a row.

[0011] Preferably, a dustproof plate is connected to the top of one end of the conductive arm, and the dustproof plate is supported on the top of the static contact base.

[0012] Preferably, the top of the base frame is provided with a threaded groove, and the bottom of the connecting cylinder is screwed into the inner side of the threaded groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, after the electric telescopic rod of the conductive arm is damaged, since there is a danger of direct contact with the conductive arm, the conductive arm can be raised or lowered by controlling the linkage. After the raising or lowering is completed, the current state can be maintained by inserting a fixing rod. The raising and lowering of the conductive arm can be manually controlled to avoid affecting the progress of subsequent work.

[0015] 2. This utility model can lift the conductive arm to disconnect the circuit by controlling the second support frame to lift it with an electric telescopic rod, and lower the conductive arm under the action of gravity to connect the circuit. The circuit can be quickly opened and closed when the electric telescopic rod is not damaged. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a disconnecting switch driving structure, including a base frame 1 and two insulators 2 mounted side-by-side on the top of the base frame 1 by bolts. A main conductive base 3 and a stationary contact base 4 are respectively mounted on the top of the two insulators 2 via mounting seats. A conductive arm 5 is movably mounted on the inner side of the main conductive base 3. This structure constitutes the main structure of a conventional disconnecting switch. The circuit is connected when the corresponding end of the conductive arm 5 falls into the stationary contact base 4. An electric telescopic rod 12 and a connecting cylinder 6 are also mounted on the top of the base frame 1. A connecting rod 7 is movably inserted into the inner side of the connecting cylinder 6. The top of the connecting rod 7 is connected to a first support frame 11 supported at the bottom of the conductive arm 5 via screws. By controlling the lifting and lowering of the connecting rod 7, the conductive arm 5 can be raised or lowered via the first support frame 11 at the top of the connecting rod 7. A push plate 8 is glued to the bottom of one side of the connecting rod 7, which facilitates the application of force to move the connecting rod 7 up and down. A strip groove for accommodating the push plate 8 is constructed on one side of the connecting cylinder 6. Corresponding fixing holes 9 are opened between the corresponding sides of the connecting rod 7 and the connecting cylinder 6, and fixing rods (not shown in the figure) are inserted between the corresponding fixing holes 9 to fix the connecting rod 7 to the ground. Figure 2When the connecting rod 7 moves upward until the push plate 8 abuts against the top of the strip groove, the fixing rod can be supported at the bottom of the connecting rod 7 to keep it in its current position. A circular handpiece 10 is glued to the side of the fixing rod away from the connecting rod 7, and the handpiece 10 can be used to easily control the insertion or removal of the fixing rod.

[0023] Specifically, the top of the output end of the electric telescopic rod 12 is connected to a second support frame 13 by screws, and the second support frame 13 is supported on the corresponding side of the bottom of the conductive arm 5. The conductive arm 5 can be raised or lowered by controlling the second support frame 13 through the electric telescopic rod 12.

[0024] Furthermore, rubber pads 15 are glued to the inner bottom of the first support frame 11 and the second support frame 13, and the rubber pads 15 are supported on the corresponding side of the bottom of the conductive arm 5, which can prevent the corresponding sides of the first support frame 11, the second support frame 13 and the conductive arm 5 from wearing each other.

[0025] Furthermore, a fixed seat 14 is fixedly sleeved on the side wall of the electric telescopic rod 12, and multiple fixing screws are screwed in a ring between the fixed seat 14 and the top of the base frame 1, which increases the stability of the electric telescopic rod 12 and ensures that the conductive arm 5 can be raised and lowered smoothly.

[0026] It is worth noting that the bottom of the two symmetrical side walls of the base frame 1 are connected to the reinforcing plates 17, and the top of the reinforcing plates 17 is provided with multiple reinforcing holes arranged in parallel. Bolts can be installed in the reinforcing holes for reinforcement, thereby increasing the overall stability of the device.

[0027] It is worth noting that a dustproof plate 16 is connected to the top of one end of the conductive arm 5, and the dustproof plate 16 is supported on the top of the static contact base 4, which can prevent dust from entering the inside of the static contact base 4.

[0028] It is worth mentioning that the top structure of the base frame 1 has a threaded groove, and the bottom of the connecting cylinder 6 is screwed into the inside of the threaded groove, which facilitates the disassembly and assembly of the connecting cylinder 6 for maintenance.

[0029] The electric telescopic rod 12 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle: The electric telescopic rod 12 controls the second support frame 13 to raise or lower the conductive arm 5, thereby disconnecting or connecting the circuit. When the electric telescopic rod 12 is damaged, the fixed rod can be pulled out first, and the connecting rod 7 can be moved upward by the push plate 8 until the push plate 8 touches the top of the strip groove. The fixed rod can be supported at the bottom of the connecting rod 7 to keep it in its current position. At this time, the conductive arm 5 will be raised and the circuit will be disconnected by the push of the first support frame 11. The fixed rod connected to the handpiece 10 can be pulled out again, and the connecting rod 7 will fall under the action of gravity. The conductive arm 5 will also fall to connect the circuit. Then the fixed rod can be inserted into the corresponding fixing hole 9 to fix the connecting rod 7. The raising and lowering of the conductive arm 5 can be manually controlled to avoid the subsequent work progress being affected by the damage to the electric telescopic rod 12.
