Description

Technical Field

[0001] The invention relates to the technical field of transformer nameplate observation, in particular to a high-voltage transformer nameplate observer with adjustable distance. Background Art

[0002] High-voltage transformers have nameplates that indicate important parameters such as the device's rated voltage, rated current, frequency, and capacity. Currently, when performing maintenance on high-voltage transformers, operators need to quickly read the information on the nameplates, typically using a nameplate viewer. Publication No. CN107277441A provides a high-voltage transformer nameplate viewer, which includes an insulating rod with a camera at one end and a display at the other. The insulating rod is internally equipped with a CCD image acquisition device, an image processing module, a battery, and a data serial port socket. This prior art observes nameplates at different locations by moving the insulating rod and camera. However, the angle of the viewer is difficult to adjust. For nameplates that are difficult to access, operators may not be able to view the nameplate at the optimal angle, resulting in blurred text or unclear information, or even complete inability to see the nameplate content, affecting the accuracy of the observation results. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a high-voltage transformer nameplate observer with adjustable distance, which solves the problem in the prior art that nameplates that are difficult to access cannot be observed at the optimal angle, thus affecting the observation results.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: A high-voltage transformer nameplate observer with adjustable distance includes an insulating cross tube, an observer body and a moving mechanism. The moving mechanism is arranged on the insulating cross tube and is used to first move the observer body to an observation position and then adjust its observation angle. The moving mechanism includes an active rod and a driven rod slidably arranged on the upper and lower sides of the insulating cross tube, and the observer body is located on one end of the driven rod, and an adjustment component arranged in the insulating cross tube for adjusting the observation angle of the observer body. A transmission component is arranged between the active rod and the driven rod. When the active rod moves, the transmission component pushes the driven rod to move in a direction opposite to the movement of the active rod. The adjustment component includes a movable seat detachably arranged at the bottom of the observer body and a rotating shaft fixed to the movable seat. A rotating component for driving the rotating shaft to rotate is arranged on the insulating cross tube.

[0005] As a further optimization scheme of the present invention, the rotating assembly includes an active rotating shaft arranged on the bottom side of the active rod, a driven rotating shaft arranged on the top side of the driven rod, and a gear group 1 arranged at one end of the driven rotating shaft and connected to the rotating shaft for transmission. The ends of the active rotating shaft and the driven rotating shaft that are away from each other extend to the outside of both ends of the insulating cross tube respectively. An adjusting dial embedded in one end of the active rod is fixed at one end of the active rotating shaft. An active cross tube is slidably provided on the active rotating shaft, and a driven cross tube is slidably provided on the driven rotating shaft. A gear group 2 is transmitted between the active cross tube and the driven cross tube.

[0006] As a further optimization solution of the present invention, a strip-shaped baffle rod is fixed to one side of the inner portion of the two active cross tubes, a strip-shaped slide groove is respectively provided on the active rotating shaft and the driven rotating shaft, and the two strip-shaped baffle rods are respectively slidably connected to the two strip-shaped slide grooves.

[0007] As a further optimization solution of the present invention, V-shaped frames are fixed to both ends of the interior of the insulating transverse tube, and one end of the two active transverse tubes is rotatably connected to both ends of the V-shaped frame through bearings.

[0008] As a further optimization scheme of the present invention, the transmission assembly includes transmission racks respectively fixed on both sides of the active rod and the driven rod, connecting shafts rotatably arranged at both ends of the inner side of the insulating cross tube through bearings, and transmission gears respectively fixed at both ends of the connecting shafts. The transmission racks on both sides of the active rod and the driven rod are respectively engaged and connected with the transmission gears at both ends of the two connecting shafts. A synchronous belt is provided between the two connecting shafts through synchronous wheel transmission, and a limit assembly for limiting the rotation direction of one of the connecting shafts is provided at the bottom of one end of the active rod.

[0009] As a further optimization scheme of the present invention, the limit assembly includes a ratchet arranged on a connecting shaft near one end of the active rod, a ratchet meshing with the ratchet on one side of the ratchet, and a rotating shaft 1 fixed at one end of the ratchet. The two ends of the rotating shaft 1 are respectively provided with limit seats fixed to the insulating cross tube through bearings.

[0010] As a further optimization scheme of the present invention, the insulating cross tube is provided with an adjustment knob near one end of the active rod, and one end of the adjustment knob is fixed with a rotating shaft 2 that passes through one end of the insulating cross tube, and a gear set 3 is rotatably provided between the rotating shaft 1 and the rotating shaft 2.

[0011] As a further optimization solution of the present invention, support plates fixed to the driven rod are provided on both sides of the bottom of the movable seat, and both ends of the rotating shaft are rotatably connected to the two support plates through bearings.

[0012] By means of the above technical solution, the present invention provides a high-voltage transformer nameplate observer with adjustable distance, which has at least the following beneficial effects compared to the prior art: 1. The present invention provides a moving mechanism to first move the observer body to the optimal observation position and then adjust its appropriate observation angle, so that the observer can adapt to nameplates on high-voltage transformers with different installation positions and different inclination angles. The operator can easily adjust the angle and length of the observer to ensure that the nameplate information can be read conveniently and clearly. At the same time, the adjustable angle allows the operator to view the nameplate at the optimal viewing angle, thereby avoiding blurring or information obstruction caused by an inappropriate angle, which helps to improve the accuracy of information reading.

[0013] 2. The present invention adjusts the observation angle of the observer body by setting an adjustment component. When observing nameplates at special angles, the observer can observe the nameplate from different perspectives by adjusting the angle, ensuring that the nameplate information is unobstructed and clearly visible. Proper angle adjustment can avoid affecting information reading due to poor vision, thereby improving observation efficiency and accuracy.

[0014] 3. The present invention sets a transmission assembly to allow the active rod and the driven rod to be pulled out from the two ends of the insulating cross tube respectively, thereby adjusting the length position of the observer body, which can flexibly adapt to the installation position and structure of different high-voltage transformers. By adjusting the length to ensure the best observation effect, the flexibility and efficiency of observation are improved.

[0015] 4. The active rod and the driven rod of the present invention can be stored in the insulating cross tube, so that the entire observer is generally designed to be more compact and can be shortened or adjusted as needed. When not in use, the observer can be conveniently stored without taking up too much space and is easy to carry. It is particularly suitable for mobile use during on-site inspections, which improves the flexibility of the nameplate observer and extends the service life of the observer.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary operators in this field without making creative efforts are within the scope of protection of the present invention.

[0019] First embodiment By comparing with the nameplate information of the equipment, the observer can help maintenance personnel confirm the technical status of the transformer and ensure the smooth progress of regular maintenance and inspection work. Since the angle adjustment of the currently used observer is not convenient, the accuracy of the observation results is affected for nameplates with difficult angles. In order to Figure 1 - Figure 4 As shown, this embodiment provides a high-voltage transformer nameplate observer with adjustable distance, which consists of an insulating cross tube 1, an observer body 2 and a moving mechanism 3. The observer body 2 is arranged at one end of the insulating cross tube 1. The use of the observer body 2 allows the operator to read the information on the nameplate safely, clearly and comfortably without directly contacting the transformer.

[0020] The moving mechanism 3 is provided on the insulating transverse tube 1 and is used to first move the observer body 2 to the observation position and then adjust its observation angle. The moving mechanism 3 includes an active rod 31 and a driven rod 32 slidably provided on the upper and lower sides of the insulating transverse tube 1. One end of the active rod 31 is provided in an L-shape, which helps to pull the active rod 31 more conveniently, and the observer body 2 is located on one end of the driven rod 32. The active rod 31 and the driven rod 32 can be stored in the insulating transverse tube 1, so that the entire observer is generally designed to be more compact and can be shortened or adjusted as needed. The observer can be conveniently stored when not in use and does not take up too much space. The insulating cross tube 1 is provided with an adjustment component 33 for adjusting the observation angle of the observer main body 2. The adjustment component 33 includes a movable seat 331 detachably arranged at the bottom of the observer main body 2, and a rotating shaft 332 fixed on the movable seat 331. The movable seat 331 is driven to rotate by the rotating shaft 332 to adjust the angle of the observer main body 2 to adapt to the special high-voltage transformer nameplate angle. Support plates 333 fixed to the driven rod 32 are provided on both sides of the bottom of the movable seat 331. The two ends of the rotating shaft 332 are rotatably connected to the two support plates 333 through bearings.

[0021] Second embodiment In order to enable the observer to observe the nameplate from different angles, ensure that the nameplate information is unobstructed and clearly visible, and appropriate angle adjustment can avoid affecting the reading of information due to poor vision, such as Figure 5 As shown, in this embodiment, a rotating assembly 334 for driving the rotating shaft 332 to rotate is provided on the insulating horizontal tube 1. Specifically, the rotating assembly 334 includes an active rotating shaft 3341 provided on the bottom side of the active rod 31, a driven rotating shaft 3342 provided on the top side of the driven rod 32, and a gear set 3343 provided at one end of the driven rotating shaft 3342 and connected to the rotating shaft 332. The gear set 3343 can be provided as a worm gear set. When the driven rotating shaft 3342 rotates, the rotating shaft 332 is driven to rotate. The ends of the active rotating shaft 3341 and the driven rotating shaft 3342, which are away from each other, respectively extend to the insulating horizontal tube 1. On the outside of both ends, one end of the active rotating shaft 3341 is fixed with an adjusting dial 3344 embedded in one end of the active rod 31. By toggling the adjusting dial 3344, it can be driven to rotate, which not only saves the installation position of the adjusting dial 3344, but also makes it more convenient to rotate the adjusting dial 3344. An active cross tube 3345 is slidably provided on the active rotating shaft 3341, and a driven cross tube 3348 is slidably provided on the driven rotating shaft 3342. A gear set 2 is provided between the active cross tube 3345 and the driven cross tube 3348. The gear set 2 can be set to a spur gear set. The active cross tube 3345 drives the driven cross tube 3348 to rotate through the gear set 2.

[0022] By rotating the adjustment dial 3344, the active shaft 3341 and the active cross tube 3345 on its outer side are driven to rotate. The active cross tube 3345 drives the driven cross tube 3348 to rotate through the gear set 2, and then drives the driven shaft 3342 to rotate. The driven shaft 3342 drives the rotating shaft 332 and the movable seat 331 to rotate through the gear set 1 3343, thereby adjusting the angle of the observer body 2. For nameplates that are difficult to access at an angle, the operator can view the nameplate at the best viewing angle, thereby avoiding blur or information obstruction caused by an inappropriate angle.

[0023] A strip baffle is fixed on one side of the interior of the two active cross tubes 3345, and a strip slide groove 3346 is respectively provided on the active rotating shaft 3341 and the driven rotating shaft 3342, and the two strip baffles are slidingly connected with the two strip slide grooves 3346 respectively. When the active rotating shaft 3341 and the driven rotating shaft 3342 slide on the inside of the two active cross tubes 3345 respectively, the strip baffle slides on the inside of the strip slide groove 3346, so that the active rotating shaft 3341 or the driven rotating shaft 3342 can only slide but not rotate on the inside of the active cross tube 3345. When the active rotating shaft 3341 and the driven rotating shaft 3342 rotate, they respectively drive the active cross tube 3345 on the outside thereof to rotate, and a V-shaped frame 3347 is fixed on both ends of the interior of the insulating cross tube 1, and one end of the two active cross tubes 3345 is rotatably connected to the two ends of the V-shaped frame 3347 through bearings, ensuring that the active cross tube 3345 is more stable during rotation.

[0024] Third embodiment In order to flexibly adapt to the installation position and structure of different high-voltage transformers, the length is adjusted to ensure the best observation effect, such as Figure 6 and Figure 7 As shown, in this embodiment, a transmission assembly 34 is provided between the active rod 31 and the driven rod 32. When the active rod 31 is moved, the transmission assembly 34 pushes the driven rod 32 to move in the opposite direction to the movement of the active rod 31. The specific implementation method is that the transmission assembly 34 includes a transmission rack 341 fixed on both sides of the active rod 31 and the driven rod 32, a connecting shaft 342 arranged at both ends of the inner side of the insulating cross tube 1 through a bearing rotation, and a transmission gear 343 fixed at both ends of the connecting shaft 342. The transmission racks 341 on both sides of the active rod 31 and the driven rod 32 are respectively connected to the two connecting shafts 3 The transmission gears 343 at both ends of 42 are meshed and connected, and a synchronous belt 344 is provided between the two connecting shafts 342 through a synchronous wheel transmission. The transmission rack 341 on the active rod 31 drives the transmission gear 343 meshed with it to rotate, and one of the transmission gears 343 drives the other transmission gear 343 to rotate through the synchronous belt 344, driving the transmission rack 341 on the driven rod 32 to move, thereby pushing the driven rod 32 to move, and the driven rod 32 drives the observer body 2 thereon to move, so that observation can be carried out for nameplates at different installation positions, thereby improving the flexibility and efficiency of observation.

[0025] In order to ensure the stability of the active rod 31 and the driven rod 32 when they are accommodated inside the insulating cross tube 1, a limit assembly 345 for limiting the rotation direction of one of the connecting shafts 342 is provided at the bottom of one end of the active rod 31. The limit assembly 345 includes a ratchet 3451 provided on the connecting shaft 342 near one end of the active rod 31, a ratchet 3452 engaged with one side of the ratchet 3451, and a rotating shaft 1 3453 fixed at one end of the ratchet 3452. The two ends of the rotating shaft 1 3453 are fixed to the end of the ratchet 3452. The ends are respectively provided with limit seats fixed to the insulating cross tube 1 through bearings for rotation. An adjusting knob 3454 is provided on the end of the insulating cross tube 1 close to the active rod 31. One end of the adjusting knob 3454 is fixed with a rotating shaft 2 3455 that passes through one end of the insulating cross tube 1. A gear set 3456 is rotatably provided between the rotating shaft 1 3453 and the rotating shaft 2 3455. The gear set 3456 can be set as a turbine worm gear set. When the rotating shaft 1 3453 rotates, it drives the rotating shaft 2 3455 to rotate.

[0026] Before observing the nameplate, first rotate the adjustment knob 3454 to drive the rotating shaft 2 3455 to rotate. The rotating shaft 2 3455 drives the rotating shaft 1 3453 to rotate through the gear set 3456. The rotating shaft 2 3455 drives the ratchet 3452 to rotate, so that the ratchet 3452 moves away from the ratchet wheel 3451. The ratchet wheel 3451 can rotate in the direction of the ratchet 3452, thereby allowing the active rod 31 to move in the direction away from the driven rod 32.

[0027] The present invention unlocks the active rod 31 through the limit assembly 345 so that it can be pulled outward, and then the active rod 31 and the driven rod 32 are respectively pulled out from the two ends of the insulating cross tube 1 through the transmission assembly 34, and then the observer body 2 is adjusted to a position suitable for observing the nameplate, and then the observation angle of the observer body 2 is adjusted through the adjustment assembly 33 to ensure that the nameplate information is unobstructed and clearly visible, which can avoid affecting information reading due to poor vision and improve observation efficiency and accuracy.

[0028] The first step is to rotate the adjusting knob 3454 so that the adjusting knob 3454 drives the second rotating shaft 3455 on one side to rotate, and the second rotating shaft 3455 drives the first rotating shaft 3453 to rotate through the third gear set 3456, and the second rotating shaft 3455 drives the ratchet 3452 on it to rotate, so that one end of the ratchet 3452 is separated from the gear on the ratchet wheel 3451, and the ratchet wheel 3451 can rotate in the direction of the ratchet 3452, and then pull the active rod 31, and the active rod 31 moves from the inside of the insulating horizontal tube 1 to the outside, and the transmission rack 341 on the active rod 31 drives the transmission gear 343 meshed with it to rotate, and one of the transmission gears 343 drives the other transmission gear 343 to rotate through the synchronous belt 344, driving the transmission rack 341 on the driven rod 32 to move, thereby pushing the driven rod 32 to move from the inside of the insulating horizontal tube 1 to the outside, and the driven rod 32 drives the observer body 2 thereon to move.

[0029] Then extend the entire observer into one side of the high-voltage transformer without contacting the high-voltage transformer. According to the position of the high-voltage transformer nameplate, place the observer body 2 on the side of the nameplate, and then rotate the adjustment dial 3344 to drive the active shaft 3341 to rotate. The active shaft 3341 drives the active cross tube 3345 on its outside to rotate. The active cross tube 3345 drives the driven cross tube 3348 to rotate through gear set 2, and then drives the driven shaft 3342 to rotate. The driven shaft 3342 drives the rotating shaft 332 and the movable seat 331 to rotate through gear set 1 3343. Adjust the angle of the observer body 2 so that it corresponds to the nameplate, and the information on the nameplate can be clearly observed.
