Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a switch setpoint adjustment device. Background Technology

[0002] With the deepening of smart grid construction, 10kV distribution lines, as a key link in the distribution network, directly affect the power supply reliability and safety level of the entire power system. Against this backdrop, the requirements for monitoring and control of the 10kV distribution network are increasingly stringent, necessitating faster and more accurate responses to line status and equipment operation. Currently, a large number of pole-mounted switches are still configured in the distribution network. These switches require setting adjustments in response to load changes and user capacity increases to adapt to system operation needs. For example, a textile company needs to increase the capacity of its transformer due to production expansion, requiring corresponding adjustments to the pole-mounted switches on its connected 10kV lines. However, when live-line work is not feasible, such adjustments typically require planned power outages, averaging about 80 minutes, which not only affects continuous power supply to users but also increases the abnormal operation time of the power grid. Currently, adjusting pole-mounted switch settings largely relies on traditional manual operation by personnel.

[0003] However, the existing manual operation method has the following problems. First, operators need to work at heights and have close contact with electrical equipment. Even if the power is off and safety measures are in place, there are still safety risks such as falls from heights, mechanical injuries, residual charges, or accidental power restoration. In addition, complex site environments can easily lead to longer operation times and operator fatigue. All operations must be carried out during the planned power outage period, making it difficult to flexibly respond to temporary setpoint adjustment needs. The preparation work is cumbersome and requires coordination with multiple departments such as power outage dispatch and maintenance, resulting in low efficiency of adjustment work and time-consuming preparation. Summary of the Invention

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0028] Reference Figures 1 to 9 As shown, the present invention discloses a switch setting adjustment device for adjusting the switches on the line poles of a high-voltage power grid.

[0029] The switch setting adjustment device includes a main body unit 1, which includes a first main body 11, a second main body 12, and a third main body 13. One end of the second main body 12 along the length direction is rotatably connected to the first main body 11, and the other end of the second main body 12 along the length direction is rotatably connected to the third main body 13. Thus, with the cooperation of the first main body 11, the second main body 12, and the third main body 13, the main body unit 1 can bend at least once and bend into a specified angle and posture to adapt to different operating scenarios. Of course, the first main body, the second main body 12, and the third main body 13 can also form a straight structure.

[0030] During operation, the operator can directly hold the first main body 11 for operation. Of course, if the length is insufficient, an extension rod can be connected to the end of the first main body 11, and the operator can hold the extension rod for operation.

[0031] The switch setting adjustment device further includes a rotation adjustment unit 2, which is disposed on the third main body 13. The rotation adjustment unit 2 can cooperate with the switch to perform adjustment operations on the switch. Specifically, the rotation adjustment unit 2 can rotate the switch to achieve the purpose of adjusting the switch. The switch setpoint adjustment device also includes an image acquisition unit 3, which is disposed on the third main body 13; the image acquisition unit 3 is disposed in parallel with the rotation adjustment unit 2; the image acquisition unit 3 is capable of real-time image acquisition of the working process of the rotation adjustment unit 2.

[0032] The switch setpoint adjustment device also includes a display unit 4, which includes a display screen. The display unit 4 is installed on the main unit 1 and has a communication connection with the image acquisition unit 3 to display the images acquired by the image acquisition unit 3 in real time. This helps operators to understand and master the operation process and ensures the accuracy of the operation.

[0033] The switch setpoint adjustment device also includes a control unit, which is communicatively connected to the main unit 1, the image acquisition unit 3 and the display unit 4 to output control signals to the main unit 1, the image acquisition unit 3 and the display unit 4.

[0034] Furthermore, the switch setting adjustment device also includes a connecting cable 10, which is disposed on the main body unit 1 so that the image acquisition unit 3, the display unit 4 and the control unit are electrically connected.

[0035] Therefore, it can be understood that the switch setting adjustment device protected by this invention comprises a main unit, a rotary adjustment unit, an image acquisition unit, and a display unit. The rotary adjustment unit is located on top of the main unit, and the image acquisition unit is located on the main unit and adjacent to it, facilitating clear image acquisition during operation and enabling operators to monitor the progress. This invention allows for remote adjustment of switch settings on high-voltage power grid poles, enabling operation without power outages or pole climbing, greatly improving reliability, safety, and work efficiency. Using this device allows for necessary training on different types of switchgear to improve work efficiency. Furthermore, the main unit of this invention is bendable for easy portability. During peak electricity consumption periods, the protection settings of multiple downstream switches can be remotely and quickly adjusted, optimizing power grid operation and reducing planned power outage duration. The switch setting adjustment device of this invention allows for flexible scheduling and adjustment as needed. Furthermore, it significantly improves operational safety, reduces the risk of falls from heights for operators, ensures their personal safety, and mitigates electrical safety risks to a certain extent. Operators are located in a safe area on the ground and maintain a sufficient safe distance from live equipment. At the same time, it reduces the physical and psychological burden on operators, reducing the number of people required for operations from at least two to just one, thus reducing manpower input.

[0036] In detail, the first body 11, the second body 12, and the third body 13 are made of rigid materials. As a preferred embodiment, the first body 11, the second body 12, and the third body 13 are made of high-strength aerospace aluminum alloy or carbon fiber composite material. Carbon fiber is the lightest material for the same strength, while aerospace aluminum alloy offers the best balance between performance and cost, allowing the body unit 1 to be both lightweight and robust. Furthermore, the grip area of ​​the first body 11 is structurally optimized to improve grip comfort and weight balance, reducing discomfort during prolonged use.

[0037] Specifically, the main body unit 1 further includes a first reversing mechanism 14, and the first main body 11 and the second main body 12 are rotatably connected through the first reversing mechanism 14; The first reversing mechanism 14 includes a first mounting base 140, a first servo motor 141, a first driving gear 142, a first driven gear 143, a second driven gear 144, a first transmission shaft 145, a second transmission shaft 146, and a first connecting base 147. The first mounting base 140 is connected to the second main body 12. The first servo motor 141 is mounted on the first mounting base 140. The first driving gear 142 is connected to the output end of the first servo motor 141. The first driven gear 143 and the second driven gear 144 are opposite to each other and mesh with the first driving gear 142. The first driven gear 143 is connected to the first connecting base 147 via the first transmission shaft 145, and the second driven gear 144 is connected to the first connecting base 147 via the second transmission shaft 146. The first connecting base 147 is connected to the first main body 11. With this configuration, the first servo motor 141 drives the first drive gear 142 to rotate, which in turn drives the first driven gear 143 and the second driven gear 144 to rotate synchronously. The first driven gear 143 and the second driven gear 144 then drive the first connecting seat 147 to rotate. Thus, depending on the situation on site, the second main body 12 can switch between different angles and postures relative to the first main body 11.

[0038] Furthermore, the main body unit 1 also includes a second reversing mechanism 15, and the second main body 12 and the third main body 13 are rotatably connected through the second reversing mechanism 15; The second reversing mechanism 15 includes a second mounting base 150, a second servo motor 151, a second driving gear 152, a third driven gear 153, a fourth driven gear 154, a third transmission shaft 155, a fourth transmission shaft 156, and a second connecting base 157. The second mounting base 150 is connected to the second main body 12. The second servo motor 151 is mounted on the second mounting base 150. The second driving gear 152 is connected to the output end of the second servo motor 151. The third driven gear 153 and the fourth driven gear 154 are arranged opposite to each other, and the third driven gear 153 and the fourth driven gear 154 respectively mesh with the second driving gear 152. The third driven gear 153 is connected to the second connecting base 157 through the third transmission shaft 155, and the fourth driven gear 154 is connected to the second connecting base 157 through the fourth transmission shaft 156. The second connecting base 157 is connected to the third main body 12. With this configuration, the second servo motor 151 drives the second drive gear 152 to rotate, which in turn drives the third driven gear 153 and the fourth driven gear 154 to rotate synchronously. The third driven gear 153 and the fourth driven gear 154 then drive the second connecting seat 157 to rotate. Thus, combined with the actual situation on site, the third main body 13 can switch different angles and postures relative to the second main body 12.

[0039] In a preferred embodiment, the rotation adjustment unit 2 includes a mounting base 20 and a positioning block 21, wherein the positioning block 21 is connected to the top end of the third body 13 via the mounting base 20. Specifically, the positioning block 21 is provided with a first limiting groove 211 and a second limiting groove 212 that are interconnected; it should be noted that the first limiting groove 211 and the second limiting groove 212 are arranged along the axial direction of the third body 13.

[0040] Preferably, the first limiting groove 211 and the second limiting groove 212 are interlocked to form a "cross-shaped" slot structure to engage with the switch, thereby allowing the operator to adjust the switch by rotating the main unit 1. Furthermore, to accommodate switch knobs of different sizes, the width and depth of the teeth (first limiting groove 211 and second limiting groove 212) of the rotating adjustment unit 2 can be adjusted according to requirements to adapt to switches with different structural styles.

[0041] Furthermore, in order to provide sufficient light so that operators can clearly observe and operate, the switch setting adjustment device also includes a light source assembly 5, which includes a light source 50 and a first connecting rod 51. The light source 50 is connected to the third main body 13 through the first connecting rod 51. The light source 50 is adjacent to the rotation adjustment unit 2, so that the image acquisition unit 3 can clearly capture the operation process, especially in the dark or in poor weather conditions.

[0042] In a preferred embodiment, one end of the first connecting rod 51 is mounted on the third body 13, the first connecting rod 51 is bent to form an L-shaped structure, and the light source 50 is connected to the other end of the first connecting rod 51.

[0043] Preferably, the first connecting rod 51 is made of a flexible, bendable material, which allows for free adjustment of the bending direction and angle for ease of use and operation.

[0044] The image acquisition unit 3 includes a camera 30 and a second connecting rod 31. The camera 30 is connected to the third main body 13 via the second connecting rod 31. The camera 30 is adjacent to the rotation adjustment unit 2. Preferably, the camera 30 can be a high-definition camera.

[0045] In detail, one end of the second connecting rod 31 is installed on the third main body 13, the second connecting rod 31 is bent to form an L-shaped structure, and the camera 30 is connected to the other end of the second connecting rod 31.

[0046] In a preferred embodiment, the light source 50 and the camera 30 are positioned opposite each other on both sides of the third body 13, thereby providing sufficient light while avoiding operational interference.

[0047] In a preferred embodiment, the switch setting adjustment device further includes an extension rod connector 6, which is disposed at the end of the first main body 11 and is used to cooperate with an extension rod. In some applications, an extension rod is mounted on the extension rod connector 6 to effectively extend the length of the switch setting adjustment device to accommodate switches with higher heights.

[0048] In addition, the first main body 11 is also provided with a power switch and a charging connector, the power switch being used to control the start and stop of the switch setting adjustment device.

[0049] Specifically, the switch setting adjustment device can be powered by an external power source or by a built-in battery.
