Description

Technical Field

[0001] This utility model relates to the field of power system safety maintenance devices, and in particular to a tool for observing disconnect switches in confined spaces. Background Technology

[0002] In power systems, disconnect switches are crucial electrical equipment, and accurate monitoring of their status is essential for ensuring the safe and stable operation of the power grid. However, in confined spaces, traditional observation methods have many limitations, making it difficult to comprehensively obtain disconnect switch status information. On the one hand, the limited space restricts the operator's range of motion, making it difficult to directly observe various parts of the disconnect switch, especially the details of some key components such as contacts and disconnectors. Furthermore, the three phases (A, B, and C) of the disconnector are very close together, and the observation window is on the side, making observation even more difficult. On the other hand, traditional observation tools, such as simple visual inspection or ordinary handheld devices, are limited by viewing angle and lighting conditions and cannot be flexibly adjusted to adapt to different angles and lighting environments. This results in the inability to accurately and comprehensively obtain key information such as the opening and closing status of the disconnect switch and the contact status, making it difficult to meet the reliability and accuracy requirements of power systems for disconnect switch status monitoring.

[0025] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0027] Reference Figure 1 This embodiment provides a tool for observing disconnect switches in confined spaces, including a moving component 1, a lifting component 2, and an observation component 3. The moving component 1 moves the entire device and the lifting component 2 horizontally within a small range. The lifting component 2 moves vertically. The observation component 3 can move with multiple degrees of freedom. In this embodiment, the moving component 1, the lifting component 2, and the observation component 3 are equipped with signal receiving and transmission devices, which facilitates the operation of the observation tool after it has entered a confined space. The above-mentioned technique for moving the entire device by the operator is existing technology and will not be described in detail here.

[0028] Specifically, the moving component 1 includes an operating table 11 and a moving wheel 12 disposed at the bottom of the operating table 11. The moving wheel 12 facilitates the movement of the device. In this embodiment, the moving component 1 is also provided with a position sensor. The position sensor is the AEAT-8800-Q24 position sensor manufactured by Broadcom. The position sensor can be based on photoelectric, electromagnetic and other principles, and can provide real-time feedback on the position coordinate information of the device in three-dimensional space.

[0029] Specifically, the lifting assembly 2 includes a movable housing 21, a first lead screw 22 rotatably disposed within the movable housing 21, a first moving block 23 movably disposed on the first lead screw 22, and a first motor 24 meshing with the first lead screw 22 and disposed outside the movable housing 21. The rotation of the first motor 24 drives the first lead screw 22 to rotate, thereby moving the first moving block 23 on the first lead screw 22. In this embodiment, the movable housing 21 is vertically disposed on the operating table 11, so the movement of the first moving block 23 on the first lead screw 22 is a vertical movement. The movable housing 21 is movably connected to the operating table 11.

[0030] Specifically, the observation component 3 includes a multi-axis robotic arm 31 and a probe component 32 mounted on the multi-axis robotic arm 31. The probe component 32 observes the disconnect switch in the confined space, while the multi-axis robotic arm 31 can provide multi-degree-of-freedom movement. The multi-axis robotic arm 31 is movably connected to the first moving block 23.

[0031] In use, the confined space is generally the gap between two pieces of equipment in a hydropower station or the space where the equipment is housed. The space is relatively narrow, with a minimum width of 15cm-20cm, but a relatively deep depth. It is inconvenient to operate by hand with the equipment over a long distance. Therefore, the moving wheels 12 facilitate the overall movement of the device and the horizontal movement of the lifting component 2 within a small range. The moving shell 21 is vertically set on the operating table 11. The first motor 24 rotates, driving the first lead screw 22 to rotate, thereby moving the first moving block 23 on the first lead screw 22, realizing the vertical up and down movement of the first moving block 23. The probe component 32 observes the disconnecting switch in the confined space, while the multi-axis robotic arm 31 can provide multiple degrees of freedom of movement, making it more suitable for operation in confined spaces.

[0032] Reference Figure 2 As an optional embodiment, the operating table 11 has a hollow accommodating space A. The operating table 11 includes a table body 111, the interior space of the table body 111 is a hollow accommodating space A, a second lead screw 112 rotatably disposed in the table body 111, a second moving block 113 movably disposed on the second lead screw 112, and a second motor 114 disposed at one end of the second lead screw 112.

[0033] When in use, when the second motor 114 rotates, the second lead screw 112, which is rotatably mounted on the side wall of the platform 111, rotates with the second motor 114. The second moving block 113 moves horizontally with the rotation of the second lead screw 112, so that the moving shell 21 mounted on the second moving block 113 can be adjusted in position within a small range.

[0034] refer to Figure 2 As an optional embodiment, the movable shell 21 includes a shell 211, which is vertically disposed on the platform 111, a first connecting block 212 disposed at one end of the shell 211, and a connecting platform 213 disposed at the other end of the shell 211. The first connecting block 212 is connected to the second movable block 113. In this embodiment, the first connecting block 212 and the second movable block 113 can be connected by a snap-fit ​​or a screw. The specific connection method is not limited. The first motor 24 is disposed on the connecting platform 213.

[0035] Furthermore, a first helical gear 241 is provided on the drive shaft of the first motor 24, and a second helical gear 221 is provided at one end of the first lead screw 22 extending out of the housing 211. The first helical gear 241 and the second helical gear 221 are meshed and connected.

[0036] Furthermore, the platform 111 is also provided with a sliding groove 1111, and the first connecting block 212 is movably connected to the sliding groove 1111.

[0037] In use, the first motor 24 is mounted on the connecting platform 213, and the first helical gear 241 meshes with the second helical gear 221. When the first motor 24 rotates, the first helical gear 241 on the drive shaft drives the first lead screw 22 to rotate, thereby causing the first moving block 23 to move in the vertical direction. The first connecting block 212 is connected to the second moving block 113, which causes the second motor 114 to rotate, driving the moving shell 21 to move within the sliding groove 1111. This movement is within a small range, which facilitates fine-tuning of the position of the probe assembly 32.

[0038] refer to Figures 3-4 As an optional embodiment, the multi-axis robotic arm 31 sequentially includes a second connecting block 311, an arm body 312, and a clamping assembly 313.

The arm body 312 is the main body for the multi-degree-of-freedom movement of the multi-axis robotic arm 31. In this embodiment, the arm body 312 is a multi-axis robotic arm that can realize multi-degree-of-freedom rotation. The arm body 312 is existing technology and will not be described in detail here. The arm body 312 is non-standard customized to meet the requirement of being suitable for operation in a narrow space of at least 15cm-20cm.

[0039] Preferably, the clamping assembly 313 includes a first connecting plate 3131 and a second connecting plate 3134. A support rod 3133 is provided between the first connecting plate 3131 and the second connecting plate 3134. A third motor 3132 is provided between the support rods 3133. A fixing member 3135 is also provided on the second connecting plate 3134. A clamping member 3137 is movably connected to the fixing member 3135. A lead screw 3136 is also provided on the drive shaft of the third motor 3132. One end of the lead screw 3136 is movably connected to the clamping member 3137. That is, the third motor 3132 drives the lead screw 3136 to rotate. When the lead screw 3136 rotates, it drives the clamping member 3137 to form different states of clamping and loosening.

[0040] Furthermore, the fixing component 3135 includes a fixing block 31351 and a support plate 31352. The fixing blocks 31351 are symmetrically arranged on the second connecting plate 3134. In this embodiment, the fixing blocks 31351 can be set on the second connecting plate 3134 by means of screws or other methods, which is not specifically limited here. The support plate 31352 is disposed on the bottom side of the fixing block 31351. The support plate 31352 is used to support the bottom of the probe assembly 32 when the clamping component 3137 clamps the probe assembly 32, so as to make the probe assembly 32 more stable.

[0041] The lead screw component 3136 includes a third lead screw 31361 and a connector 31362. The third lead screw 31361 is mounted on the drive shaft of the third motor 3132. A connecting hole 31341 is provided on the second connecting disc 3134, through which the third lead screw 31361 passes. The connector 31362 is located at the end away from the third motor 3132 and has a threaded hole. When the third lead screw 31361 rotates, it can drive the connector 31362 to move.

[0042] The clamping member 3137 includes a clamping head 31371 and a connecting rod 31372. One end of the connecting rod 31372 is hinged to the fixing block 31351, and the other end of the connecting rod 31372 is hinged to the clamping head 31371. The connecting rod 31372 is also hinged to the connecting head 31362. In this embodiment, a rubber pad can also be provided on the opposite side of the clamping head 31371 to increase the friction between the clamping head 31371 and the camera 321.

[0043] In use, the second connecting block 311 is used to connect the multi-axis robotic arm 31 to the first moving block 23 to realize the vertical height movement of the multi-axis robotic arm 31. The arm body 312 is the main body of the multi-degree-of-freedom movement of the multi-axis robotic arm 31. The rotation of the third motor 3132 drives the third lead screw 31361 to rotate, thereby causing the connector 31362 to move on the third lead screw 31361. When the connector 31362 approaches the second connecting plate 3134, the clamping head 31371 is clamped by pulling the connecting rod 31372.

The illumination lamp 322 is used for illumination in dark environments, and the cleaning assembly 323 is used to clean the camera in a timely manner when dust affects observation in a confined environment. In this embodiment, the camera 321 has an image sensor inside, which is a commercially available SmartSens SC136HGS image sensor. The image sensor converts light signals into electrical signals, and after analog-to-digital conversion and other processing, finally generates a usable digital image. The camera 321 is also equipped with a temperature sensor, which is a commercially available ADT7420 temperature sensor, which can monitor the temperature of the device's operating environment.

[0045] Furthermore, the cleaning component 323 includes a fixing plate 3231. A fourth motor 3232 is disposed on the side of the fixing plate 3231 near the multi-axis robotic arm 31. A first connector 32331 is disposed on the drive shaft of the fourth motor 3232. The first connector 32331 is rotatably disposed on the fixing plate 3231. The first connector 32331 is movably connected to a second connector 32332, and the second connector 32332 is disposed at an eccentric position on the first connector 32331. A wiping strip 3234 is also rotatably disposed on the fixing plate 3231. The second connector 32332 is movably connected to the wiping strip 3234. The wiping strip 3234 is in contact with the lens surface of the camera 321. In this embodiment, a dust sensor is disposed on the cleaning component 323. The dust sensor is a commercially available GP2Y1014AU dust sensor. The dust sensor obtains dust concentration data in the environment by detecting the influence of suspended dust particles in the air on physical properties such as light scattering.

[0046] In use, the first connector 32331 is movably connected to the second connector 32332, the second connector 32332 is set at an eccentric position of the first connector 32331, and the second connector 32332 is movably connected to the wiping strip 3234.
