Description

Technical Field

[0001] This utility model relates to a switch operating tool, and more particularly to a telescopic multi-functional switch operating insulating tool. Background Technology

[0002] During the operation and maintenance of hydropower station power systems, it is frequently necessary to perform opening and closing operations on various switches. However, due to the limitations of the hydropower station's installation environment, the installation locations of switches are often obscured by other equipment, preventing operators from making close-range contact with the switches. Secondly, the potential for electrical hazards posed by the switches and surrounding equipment also prevents operators from directly inserting their hands into gaps in the electrical equipment to operate the switches, further increasing the difficulty of switching them on and off.

[0003] Based on this, existing hydropower station electrical operators create specialized insulated operating tools for different switch locations and switch types. Each tool has a specific length and interface shape, allowing operators to hold it and reach inside electrical equipment to perform opening and closing operations. However, this approach has drawbacks. Firstly, because there are many switches in hydropower stations that cannot be accessed at close range, and each switch requires a corresponding insulated operating tool, operators need to carry a large number and variety of insulated operating tools, significantly increasing the difficulty of carrying and searching for them.

[0004] On the other hand, because the length of the rod of the insulated operating tool is fixed, it cannot be operated in the normal way if special circumstances occur, such as when the operator is blocked by external objects and cannot reach the operating position, which increases the difficulty of operation and maintenance for the operator.

[0005] Therefore, existing insulating operating tools used for electrical switches in hydropower stations suffer from poor versatility and inconvenience in operation. Utility Model Content

[0006] The purpose of this invention is to provide a telescopic, multi-functional switch operating insulation tool. It features good versatility and ease of operation.

[0007] The technical solution of this utility model: a telescopic multi-functional switch operating insulating tool, including a telescopic rod, the end of which is detachably connected to a multi-functional operating head, and the multi-functional operating head is provided with push-button switch operating components, single-phase circuit breaker operating components, multi-phase circuit breaker operating components and rotary switch operating components around its perimeter; the telescopic rod includes multiple tubes arranged in an inner and outer nested manner, and adjacent tubes are connected to each other by limiting parts, which are used to adjust the telescopic position of adjacent tubes along the length direction; The push-button switch operating component is cylindrical in shape and is used to press the push-button switch. One end of the single-phase circuit breaker operating component extends to the outside of the multi-functional operating head and has two parallel grooves. The two grooves are located on the upper and lower sides of the single-phase circuit breaker operating component and are used to engage with the handle of the single-phase air switch. One end of the multi-phase circuit breaker operating component extends to the outside of the multi-functional operating head and is provided with two symmetrical arc grooves. The two arc grooves are located on the upper and lower sides of the multi-phase circuit breaker operating component and are used to engage the handle of the multi-phase circuit breaker with each other. The rotary switch operating component is U-shaped and located on one side of the multi-functional operating head. The rotary switch operating component is used to engage the knobs of the rotary switch.

[0008] In the aforementioned telescopic multi-functional switch operating insulating tool, the limiting part includes external threads and internal threads respectively provided on adjacent tubes, and the adjacent tubes are connected to each other through the external threads and internal threads.

[0009] In the aforementioned telescopic multi-functional switch operating insulating tool, one end of the tube is connected to an external thread via a stepped portion; a retaining ring is provided on the tube at the end of the internal thread, and the retaining ring is used to axially limit the stepped portion.

[0010] In the aforementioned telescopic multi-functional switch operating insulation tool, an annular mounting cavity is formed between adjacent tubes. The limiting part includes a first friction band, a second friction band, and a third friction band. The first friction band is disposed on the outer wall of the tube inside the mounting cavity and located on the bottom side of the tube. The second friction band is disposed on the inner wall of the tube outside the mounting cavity and completely covers the inner wall of the tube along its length. The first and second friction bands are staggered relative to each other along the circumference of the tube. The third friction band is disposed on the inner wall of the tube outside the mounting cavity and on the top side of the tube. After the third and second friction bands are closed, they completely cover the inner wall of the tube along the circumference of the tube. The thickness of one side of the mounting cavity is the same as the thickness of the first, second, and third friction bands.

[0011] In the aforementioned telescopic multi-functional switch operating insulating tool, the telescopic rod and the multi-functional operating head are connected to each other via a threaded block and a threaded groove. The threaded groove is located at the bottom center of the multi-functional operating head, and the threaded block is fixedly connected to the end of the telescopic rod.

[0012] In the aforementioned telescopic multi-functional switch operating insulating tool, a push-pull molded case circuit breaker operating component is rotatably connected to one side of the multi-functional operating head via a pin. The push-pull molded case circuit breaker operating component has a rectangular opening at the end away from the pin, which is used to engage with the handle of the push-pull molded case circuit breaker.

[0013] In the aforementioned telescopic multi-functional switch operating insulating tool, the inner wall of the rectangular opening is provided with anti-slip pads around its perimeter.

[0014] Compared with the prior art, this utility model has the following characteristics: (1) By limiting the structure of the multi-functional operating head, the present invention enables the operation components of the multi-functional operating head to be used for opening and closing operations of push-button switches, single-phase air switches, multi-phase air switches and rotary switches respectively. This allows the operator to select different operation components according to the type of switch, thereby realizing the opening and closing operation of different types of switches and improving the versatility of the present invention. By setting multiple tubes in an inner and outer nested manner and connecting them with each other through the limiting part, the operator can adjust the length of the telescopic rod as needed, thereby further improving the versatility of the present invention and making it convenient for the operator to carry and operate. (2) By connecting adjacent pipes with external and internal threads, the pipes can expand and contract by rotation, and the pipes will not be squeezed to form axial sliding after they are rotated into place, thereby improving the expansion and contraction stability of the telescopic rod. (3) By connecting adjacent pipes through the mounting cavity, the first friction belt, the second friction belt and the third friction belt, the operator can extend the pipe to a specified length and then rotate it to make the first friction belt and the second friction belt overlap each other, thereby using the contact between the two to form an interference fit between the adjacent pipes, that is, to realize the axial limiting function of the pipe and effectively improve the operator's ease of operation of the telescopic rod; on this basis, by setting the third friction belt, on the one hand, the pipe can be fitted and limited after the first friction belt and the second friction belt overlap each other, improving the limiting stability of the pipe; on the other hand, it can also play an axial limiting function for the first friction belt, preventing the first friction belt from sliding directly out from the adjacent pipe with the pipe, thus improving the stability of the use of this utility model; Therefore, this utility model has the characteristics of good versatility and convenient operation.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example 1. Telescopic multi-functional switch operating insulating tool, configured as follows: Figure 1-2 As shown, the device includes a telescopic rod, with a multi-functional operating head 1 detachably connected to the end of the telescopic rod. The multi-functional operating head 1 is equipped with a push-button switch operating component 2, a single-phase circuit breaker operating component 3, a multi-phase circuit breaker operating component 4, and a rotary switch operating component 5 around its perimeter. The telescopic rod includes multiple tubes 6 arranged in an inner and outer nested configuration. Adjacent tubes 6 are interconnected via limiting parts, which are used to adjust the telescopic position of adjacent tubes 6 along their length. The push-button switch operating component 2 is cylindrical in shape, and the top of the push-button switch operating component 2 forms a spherical surface. When operating, the operator uses this spherical surface to press the button of the push-button switch, thereby realizing the opening and closing of the push-button switch. One end of the single-phase circuit breaker operating component 3 extends to the outside of the multi-functional operating head 1 and is provided with two parallel grooves. The two grooves are located on the upper and lower sides of the single-phase circuit breaker operating component 3, respectively. When operating, the operator can engage one side of the groove with the handle of the single-phase air switch, and then push and pull the telescopic rod to open or close the single-phase air switch. One end of the multi-phase circuit breaker operating component 4 extends to the outside of the multi-functional operating head 1 and is provided with two symmetrical arc grooves. The two arc grooves are located on the upper and lower sides of the multi-phase circuit breaker operating component 4, respectively. When operating, the operator can engage one side of the arc groove with the handle of the multi-phase air switch, and then push and pull the telescopic rod to open or close the multi-phase air switch. The arc grooves ensure that the handle remains in contact with the multi-phase circuit breaker operating component 4 during rotation, preventing the handle from snapping back due to changes in their relative positions. The rotary switch operating component 5 is U-shaped and located on one side of the multi-functional operating head 1. When operating, the operator can engage the U-shaped groove with the knob of the rotary switch, and then rotate the telescopic rod to drive the knob to rotate to achieve the opening and closing action.

[0019] The limiting part includes an external thread 7 and an internal thread 8 respectively provided on adjacent tube bodies 6, and the adjacent tube bodies 6 are connected to each other by the external thread 7 and the internal thread 8; the operator can adjust the length of the telescopic rod by screwing in or out of the tube body 6.

[0020] One end of the tube body 6 is connected to the external thread 7 via the stepped portion 9; a retaining ring 10 is provided on the tube body 6 at one end of the internal thread 8, and the retaining ring 10 is used to axially limit the stepped portion 9.

[0021] The telescopic rod and the multi-functional operating head 1 are connected to each other via a threaded block 15 and a threaded groove. The threaded groove is located at the bottom center of the multi-functional operating head 1, and the threaded block 15 is fixedly connected to the end of the telescopic rod.

[0022] One side of the multi-functional operating head 1 is rotatably connected to a push-pull molded case circuit breaker operating component 17 via a pin 16. The push-pull molded case circuit breaker operating component 17 has a rectangular opening at the end away from the pin 16. When operating, the operator puts the handle of the molded case circuit breaker into the rectangular opening, and then pushes and pulls the telescopic rod to move the end of the push-pull molded case circuit breaker operating component 17 closer to the pin 16.

[0023] The inner wall of the rectangular opening is provided with anti-slip pads to prevent the handle from slipping out during the pushing and pulling of the telescopic rod.

[0024] In this embodiment, the operator first adjusts the length of the telescopic rod according to the switch position and selects the required operating component according to the switch type. After the telescopic rod length is adjusted to the correct position, the operator can insert the multi-functional operating head 1 into the electrical equipment and operate the switch to open or close it using the corresponding operating component.

[0025] Example 2. Telescopic multi-functional switch operating insulating tool, configured as follows: Figure 3-5 As shown, it includes a telescopic rod, and a multi-functional operating head 1 is detachably connected to the end of the telescopic rod. The multi-functional operating head 1 has the same shape as in Embodiment 1. The telescopic rod includes multiple tubes 6 arranged in an inner and outer nested manner. Adjacent tubes 6 are connected to each other by a limiting part, which is used to adjust the telescopic position of adjacent tubes 6 along the length direction.

[0026] The outer diameter of the inner tube 6 is smaller than the inner diameter of the outer tube, forming an annular mounting cavity 11 between adjacent tubes 6. The limiting part includes a first friction band 12, a second friction band 13, and a third friction band 14. The first friction band 12 is disposed on the outer wall of the tube 6 inside the mounting cavity 11 and located on the bottom side of the tube 6. The second friction band 13 is disposed on the inner wall of the tube 6 outside the mounting cavity 11 and completely covers the inner wall of the tube 6 along its length. The first friction band 12 and the second friction band 13 are staggered with each other along the circumference of the tube 6. The third friction band 14 is disposed on the inner wall of the tube 6 outside the mounting cavity 11 and on the top side of the tube 6. After the third friction band 14 and the second friction band 13 are enclosed, they completely cover the inner wall of the tube 6 along the circumference of the tube 6. The thickness of one side of the mounting cavity 11 is the same as the thickness of the first friction band 12, the second friction band 13, and the third friction band 14.

[0027] The tube body 6 is made of epoxy resin glass fiber; the first friction band 12, the second friction band 13 and the third friction band 14 can all be made of adhesive tape and adhered to the tube body 6.

[0028] The telescopic rod and the multi-functional operating head 1 are connected to each other via a threaded block 15 and a threaded groove. The threaded groove is located at the bottom center of the multi-functional operating head 1, and the threaded block 15 is fixedly connected to the end of the telescopic rod.

[0029] The telescopic rod and the multi-functional operating head 1 are connected to each other via a threaded block 15 and a threaded groove. The threaded groove is located at the bottom center of the multi-functional operating head 1, and the threaded block 15 is fixedly connected to the end of the telescopic rod.

[0030] Compared to Embodiment 1, this embodiment adjusts the structure of the limiting part. By forming a mounting cavity 11 between adjacent tubes 6 to accommodate a single-layer friction band, when the first friction band 12 is misaligned with the second friction band 13 and the third friction band 14, the tube 6 can slide and extend freely within the mounting cavity 11. When the friction band 12 partially or completely overlaps with the second friction band 13 or the third friction band 14, an interference fit is formed between the inner and outer tubes 6, thereby achieving axial limiting of the tube 6 through friction.

[0031] Based on this, when it is necessary to adjust the length of the telescopic rod, the operator can extend the inner tube 6 to the specified length, and then rotate the inner tube 6 so that the first friction strip 12 at its end overlaps with the second friction strip 13 on one side, thereby achieving the positioning of the tube 6.
