Description

Technical Field

[0001] This utility model relates to the field of operating lever connections, and more specifically, to a manual operating lever for a disconnector switch that allows for rapid opening and closing. Background Technology

[0002] Operating levers for opening and closing circuit breakers are commonly found in electrical equipment such as circuit breakers and disconnect switches. Conventional operating levers for opening and closing circuit breakers are generally short, which reduces the probability of accidental operation caused by personnel moving near the equipment (such as during inspections and maintenance), thus avoiding safety accidents such as power outages and short circuits.

[0003] Chinese patent application number CN202323240061.9 discloses a switch handle. This design uses a locking structure to lock the handle when it is turned to open or close, preventing it from rotating and maintaining a stable open or closed state, thus reducing the risk of accidental operation. However, in summer or in enclosed power distribution rooms, operators are prone to sweating due to heat. If there is sweat on their hands when operating the lever, the moisture will form a water film on the surface of the skin and the lever, reducing the static friction between the two. When the lever is turned, insufficient friction makes it difficult for the operator to apply enough torque, or even cause the hand to slip and be injured due to excessive force. Secondly, the lever is generally not completely insulated, and sweat may become a conductive medium, increasing the risk of electric shock.

[0004] Therefore, a manual operating lever for a disconnector switch that allows for rapid opening and closing of circuits was proposed to address the aforementioned issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a manual operating lever for a disconnecting switch that allows for rapid opening and closing. Through the insulating strip and anti-slip sleeve of the protective component, as well as the motor and worm gear transmission structure of the connecting component, safe and efficient operation is achieved. The insulating strip isolates current and reduces the risk of electric shock, while the anti-slip sleeve increases friction, ensuring stable operation in complex environments. The worm gear transmission, in conjunction with the motor, enables the automatic opening and closing of the insulating clamping strip, providing stable clamping force and precise control of the action, reducing manual adjustments, avoiding safety hazards, and balancing safety and efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A manual operating lever for a quick-closing disconnector includes a protective component, the front end of which is fixedly connected to a connecting component; the protective component includes a handle, the outer wall of which is fixedly connected to multiple equidistant insulating strips, and the outer wall of each insulating strip is fixedly connected to an anti-slip sleeve; the connecting component includes a housing communicating with the handle, and the interior of the housing is movably connected to multiple equidistant insulating clamping strips.

[0008] Furthermore, a fixed ring is fixedly connected inside the outer shell, a rotating ring is rotatably connected to the front end of the fixed ring, a driven ring is fixedly connected to the front end of the rotating ring, a plurality of equidistant connecting posts are fixedly connected to the front end of the driven ring, a transmission ring is fixedly connected to the front end of the connecting posts, and a worm gear is fixedly connected to the front end of the transmission ring.

[0009] Furthermore, the rear end of the transmission ring is rotatably connected to a plurality of connecting blocks that are staggered with the connecting post, the rear end of the connecting block is fixedly connected to a sleeve block, and the sleeve block is slidably connected to a connecting arm.

[0010] Furthermore, one end of the connecting arm is fixedly connected to a rotating shaft that is rotatably connected to the fixed ring.

[0011] Furthermore, the other end of the connecting arm is fixedly connected to an adapter plate that penetrates the front end of the housing.

[0012] Furthermore, the end of the adapter plate furthest from the connecting arm is fixedly connected to the insulating clamping strip.

[0013] Furthermore, a motor is fixedly connected inside the housing, and a worm gear that is rotatably connected to the transmission end of the motor is fixedly connected to the housing, and the worm gear meshes with a worm wheel.

[0014] In summary, this utility model has the following beneficial effects:

[0015] (1) This solution effectively improves the safety and stability of the operation process through the insulating strip and anti-slip sleeve in the protective components. The insulating strip is made of a material with excellent insulation performance, which fully isolates the handle from the operator's hands and greatly reduces the risk of electric shock. The special texture design on the surface of the anti-slip sleeve, combined with the increased grip area of ​​the insulating strip, can significantly increase the friction even if the operator's hands are sweaty, avoiding operation errors or hand injuries caused by slipping, and ensuring that the operator can operate safely and reliably in complex environments, such as high temperatures in summer and enclosed power distribution rooms.

[0016] (2) This solution utilizes the motor and worm gear transmission structure in the connecting assembly to realize the automated opening and closing control of the insulating clamping strip. The worm gear transmission has the characteristics of speed reduction and torque increase and self-locking. It can not only provide a stable and sufficient clamping force for the insulating clamping strip to ensure that the opening and closing operation rod is firmly clamped and prevent loosening, but also accurately realize the clamping or releasing action by controlling the direction of the motor, reducing the manual adjustment link, greatly improving the opening and closing operation efficiency, and avoiding the safety hazards that may be caused by direct manual contact with the operation rod, thus achieving a dual improvement in safety and efficiency.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0024] Reference Figures 1-4 As shown, the manual operating lever for the disconnecting switch with rapid opening and closing in a preferred embodiment of this utility model includes a protective component 1, with a connecting component 2 fixedly connected to the front end of the protective component 1; the protective component 1 includes a handle 101, with multiple equidistant insulating strips 102 fixedly connected to the outer wall of the handle 101, and an anti-slip sleeve 103 fixedly connected to the outer wall of the insulating strips 102; the connecting component 2 includes a housing 201 communicating with the handle 101, with multiple equidistant insulating clamping strips 214 movably connected inside the housing 201;

[0025] By setting an insulating strip 102 on the outer wall of the handle 101, the insulation performance of the operating rod is improved, preventing electric shock to the operator and ensuring safety. The anti-slip sleeve 103 covers the outside of the insulating strip 102, increasing the surface friction of the handle 101, making it easier for the operator to hold, and improving the stability and comfort of manual operation. The insulating clamping strip 214 is used to clamp the operating rod for opening and closing the circuit breaker. The insulating material prevents conductivity and ensures electrical isolation during operation.

[0026] A fixed ring 202 is fixedly connected inside the outer casing 201. A rotating ring 204 is rotatably connected to the front end of the fixed ring 202. A driven ring 203 is fixedly connected to the front end of the rotating ring 204. A plurality of equidistant connecting posts 206 are fixedly connected to the front end of the driven ring 203. A transmission ring 205 is fixedly connected to the front end of the connecting posts 206. A worm gear 209 is fixedly connected to the front end of the transmission ring 205.

[0027] The fixed ring 202 provides support, and the rotating ring 204 can rotate on it, forming the basis of the transmission structure and realizing the transmission of the rotational motion of the driven ring 203. The driven ring 203 moves in conjunction with the transmission ring 205 through the connecting column 206, which facilitates the linkage of subsequent components. The transmission ring 205 fixes the worm gear 209, and the rotation of the worm gear 209 drives the subsequent mechanical structure, providing a power source for the opening and closing action of the insulating clamping strip 214.

[0028] The rear end of the transmission ring 205 is rotatably connected to multiple connecting blocks 210 that are staggered with the connecting post 206. The rear end of the connecting block 210 is fixedly connected to a sleeve block, and the sleeve block is slidably connected to a connecting arm 211.

[0029] The connecting block 210 is fixed to the transmission ring 205. The sleeve allows the connecting arm 211 to slide, forming a movable connection structure. This allows the connecting arm 211 to swing with the movement of the transmission ring 205. The connecting arm 211 acts as a transmission hub, transmitting the movement of the transmission ring 205 to the adapter plate 213 to realize the transmission of mechanical action and ensure the opening and closing movement of the insulating clamping strip 214.

[0030] One end of the connecting arm 211 is fixedly connected to a rotating shaft 212 that is rotatably connected to the fixed ring 202;

[0031] The pivot 212 provides a pivot point for the connecting arm 211, allowing the connecting arm 211 to swing around a fixed point during transmission, ensuring the stability of the motion trajectory and preventing deviation or jamming during transmission.

[0032] The other end of the connecting arm 211 is fixedly connected to an adapter plate 213 that penetrates the front end of the housing 201;

[0033] The adapter plate 213 serves as an intermediate component between the connecting arm 211 and the insulating clamping strip 214, transmitting the mechanical movement of the connecting arm 211 to the insulating clamping strip 214. At the same time, by penetrating the front end of the housing 201, the insulating clamping strip 214 better clamps the opening and closing operating rod.

[0034] The end of the adapter plate 213 away from the connecting arm 211 is fixedly connected to the insulating clamping strip 214;

[0035] The movement of the adapter plate 213 directly drives the movement of the insulating clamping strip 214, enabling the clamping strip to open or close synchronously, thereby achieving precise clamping or separation of the opening and closing operation rod and meeting the operational requirements for rapid opening and closing.

[0036] A motor 207 is fixedly connected inside the housing 201. The transmission end of the motor 207 is fixedly connected to a worm 208 that is rotatably connected to the housing 201. The worm 208 meshes with a worm wheel 209.

[0037] Power is provided by motor 207, which drives worm gear 208 to worm wheel 209, creating a transmission effect of speed reduction and torque increase. This allows worm wheel 209 to stably drive transmission ring 205 and subsequent structures, achieving automated control of insulating clamping bar 214, improving the efficiency and reliability of opening and closing operations. The precision and self-locking of the worm gear 208 and worm wheel 209 transmission ensure the stability of power transmission. At the same time, the clamping or releasing of the clamping bar can be achieved by controlling the direction of motor 207.

[0038] Specific implementation process: First, when it is necessary to open or close the disconnecting switch, the operator holds the handle 101. The anti-slip sleeve 103 and the insulating strip 102 work together to ensure a stable and safe grip. The operator then controls the motor 207 to run. The rotation of the motor 207 drives the worm gear 208 to rotate. The worm gear 208 meshes with the worm wheel 209, transmitting power to the worm wheel 209. The worm wheel 209 drives the driven ring 203 and the rotating ring 204 to rotate synchronously via the transmission ring 205 and the connecting post 206. Simultaneously, the connecting block 210 at the rear end of the transmission ring 205 moves with the transmission ring, pushing the connecting arm 211 inside the sleeve to swing around the pivot 212. The adapter plate 213 at the other end of the connecting arm 211... This causes the insulating clamping strip 214 to open or close. When the insulating clamping strip 214 is closed, it can tightly clamp the control lever for opening and closing the circuit breaker. Then, the control lever is manually rotated to the closing or opening position by the handle 101. After opening or closing, the motor 207 is driven in reverse to open the insulating clamping strip 214 and disengage it from the control lever to prevent accidental contact. During operation, the insulating strip 102 and the insulating clamping strip 214 provide electrical isolation throughout the process to prevent electric shock to the operator. The anti-slip sleeve 103 increases friction to prevent the hand from slipping due to sweat, improving operational safety and efficiency. The self-locking characteristic of the worm gear drive ensures stable clamping and avoids accidental operation.
