Description

Technical Field

[0001] The utility model relates to the technical field of disconnectors, and particularly relates to a disconnector operating mechanism. Background Art

[0002] A disconnector, also known as a "switch blade", is a switching device that plays an isolating role in a circuit. Its main functions are to isolate the power supply, perform switching operations, and connect and disconnect small current circuits. A significant feature of the disconnector is its lack of arc extinguishing ability, which means it can only open and close the circuit under no load current. In terms of working principle, the disconnector physically disconnects the circuit to ensure safety. The operator manually or electrically operates the disconnector to open it, thereby physically disconnecting the circuit to ensure no current flow. In addition, when the disconnector is in the open state, it provides an obvious physical break point to ensure that the operator can see that the circuit is disconnected.

[0003] The disconnector is generally considered safe under correct operation, but any operation involving high-voltage equipment poses certain risks. For example, when the disconnector fails to correctly disconnect the circuit, or the operator mistakenly believes that the circuit has been disconnected, an electric shock accident may occur. Therefore, there are great potential safety hazards in the operating mechanism of traditional disconnectors.

[0004] In view of this, a disconnector operating mechanism is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a disconnector operating mechanism to solve the problem that an electric shock accident may occur when the disconnector fails to correctly disconnect the circuit or the operator mistakenly believes that the circuit has been disconnected.

A sleeve is detachably sleeved on the outer frame. A plurality of pairs of hinge blocks hinged to the hinge rod are arranged in pairs on the sleeve. The middle of the sleeve is hollow and a rotating cylinder is rotatably connected to the middle thereof. A switch groove adapted to the size of the knob is formed on the rotating cylinder. The rotating cylinder is used to drive the knob to rotate when rotating to control the disconnector.

[0007] Further, the number of locking rods is adapted to the number of the plurality of locking grooves, and locking blocks adapted to the locking grooves are fixedly connected to the locking rods. The locking blocks are used to fixedly connect the sleeve and the switch body after being inserted into the locking grooves.

[0008] Furthermore, a hinge rod is fixedly connected to the locking rod, and a plurality of locking blocks hinged to the hinge rod are correspondingly provided on the sleeve. One end of the locking rod away from the locking block is fixedly connected to a spring, one end of the spring is fixedly connected to the locking rod, and the other end of the spring is fixedly connected to the surface of the sleeve.

[0009] Furthermore, a connecting rod is fixedly connected to a side of the rotating drum away from the switch body, a first bevel gear is fixedly connected to the connecting rod, a second bevel gear is meshingly connected to the first bevel gear and is staggered with the first bevel gear, and the second bevel gear is used to drive the rotating drum to rotate when rotating to complete the adjustment of the isolating switch.

[0010] Furthermore, a bracket is fixedly connected to the bottom of the sleeve, a rotating rod is rotatably connected to the bracket, the rotating rod is made of insulating material, the rotating top is fixedly connected to the bottom of the second bevel gear, an adjusting ring is fixedly connected to the bottom of the rotating rod, and the adjusting ring is used to adjust the isolating switch during rotation.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 .

[0025] The isolating switch operating mechanism of the present utility model includes a switch body 1 and a knob 3 provided on the switch body 1 for controlling the isolating switch. An outer frame 2 fixedly connected to the switch body 1 is provided on the outside of the knob 3. A plurality of locking grooves 21 are formed on the outer frame 2. A sleeve 4 is detachably sleeved on the outer frame 2. A plurality of locking rods 5 are rotatably installed on the sleeve 4. The middle of the sleeve 4 is hollow and a rotating cylinder 6 is rotatably connected to the middle thereof. A switch groove 61 adapted to the size of the knob 3 is formed on the rotating cylinder 6. The rotating cylinder 6 is used to drive the knob 3 to rotate when rotating to control the isolating switch.

[0026] Among them, the number of locking rods 5 is adapted to the number of multiple locking grooves 21, and the locking rods 5 are fixedly connected with locking blocks 51 adapted to the locking grooves 21, the locking blocks 51 are used to fix the sleeve 4 and the switch body 1 after being inserted into the locking grooves 21, and the locking rods 5 are fixedly connected with hinged rods 52, and the sleeve 4 is provided with multiple pairs of hinged blocks 53 hinged to the hinged rods 52 in pairs, and the end of the locking rod 5 away from the locking block 51 is fixedly connected with a spring 54, one end of the spring 54 is fixedly connected to the locking rod 5, and the other end of the spring 54 is fixedly connected to the surface of the sleeve 4.

[0027] That is to say, when the sleeve 4 and the switch body 1 are installed or disassembled, it is necessary to first press down the end of the locking rod 5 away from the locking block 51, and then the locking rod 5 will return to its initial state under the action of the spring 54, making the disassembly and assembly of the sleeve 4 and the switch body 1 very convenient. In addition, through the arrangement of multiple locking rods 5 and locking grooves 21, the connection between the switch body 1 and the sleeve 4 is more secure.

[0028] In addition, a connecting rod 62 is fixedly connected to the side of the rotating drum 6 away from the switch body 1, and a first bevel gear 7 is fixedly connected to the connecting rod 62. The first bevel gear 7 is meshingly connected to a second bevel gear 8 that is staggered with the first bevel gear 7. The second bevel gear 8 is used to drive the rotating drum 6 to rotate when rotating to complete the control of the isolating switch.

[0029] Again, the bottom of the sleeve 4 is fixedly connected to a bracket 10, and the bracket 10 is rotatably connected to a rotating rod 9, the rotating rod 9 is made of insulating material, and the rotating top is fixedly connected to the bottom of the second bevel gear 8, and the bottom of the rotating rod 9 is fixedly connected to an adjusting ring 14, and the adjusting ring 14 is used to adjust the isolating switch during rotation, and the bracket 10 is fixedly connected to a motor 11, and the output end of the motor 11 is fixedly connected to a first gear 12, and the first gear 12 is meshed with a second gear 13, and the second gear 13 is fixedly connected to the rotating rod 9.

[0030] That is to say, there are two ways to adjust the rotation of the knob 3 by controlling the rotation of the drum 6. One is that under normal conditions, the direction of the drum 6 and the knob 3 can be controlled by controlling the forward or reverse rotation of the motor 11 during use. When the motor 11 is damaged, the drum 6 and the knob 3 can still be controlled by manually rotating the adjustment ring 14. The motor 11 can be set to a remotely controlled motor 11, so that the operator can operate in a safer operating environment.

[0031] In addition, if Figure 2As shown, on one side of the rotary drum 6 away from the switch body 1, there is a direction indicator 15 for indicating the rotation direction of the knob 3, enabling the operator to judge the direction of the knob 3 according to the direction of the direction indicator 15. It should be noted that when specifically setting, the bracket 10, the connecting rod 62 and the rotating rod 9 should all be made of insulating resins or plastics such as polyethylene to further improve the safety during operation.

[0032] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
