Description

Technical Field

[0001] The present invention relates to the technical field of line loss detection in a transformer area, and in particular to a line loss detection device in a transformer area. Background Art

[0002] Line loss in the power distribution area refers to the energy loss caused by physical characteristics such as resistance, inductance, and capacitance during the transmission and distribution of electricity. It is not only directly related to the economic benefits of power companies, but also poses a potential threat to the safe and stable operation of the power grid. Therefore, it is necessary to use a detection device to perform real-time detection of key parameters in the power distribution area, and to judge line loss abnormalities through real-time detection. However, this detection device has the following defects after specific use and comparison with existing technologies:

[0003] Since the height of the distribution box is generally high, and the staff needs to hold the detection device to operate at high altitude, the staff needs to insert the connecting wire into the bottom of the detection device for connection. Since the staff is standing in the air and needs to stabilize themselves with one hand, they can only perform wiring with one hand. When wiring with one hand, the detection device will slide inside the distribution box, making it difficult to insert the connecting wire into the correct hole. When the staff uses both hands to connect the wires, they cannot stabilize themselves, which can easily cause shaking or loss of balance during the operation, greatly increasing the risk of falling.

[0004] Therefore, the present invention proposes a transformer area line loss detection device to make up for and improve the deficiencies of the prior art. Summary of the invention

The guide plate 55 is used to limit the sliding rod 54 from sliding inside the guide plate 55. By pushing the two sides of the bottom of the sliding member 52, the detector 1 can be lifted upward inside the distribution cabinet, thereby ensuring that the staff has enough space to install the connecting wires and avoiding incorrect connection of the connecting wires.

[0045] The complete working principle and steps of the above embodiment are as follows:

[0046] refer to Figures 1 to 4 As shown, when the device is in the initial state, the outer surface of the push member 13 is attached to the side of the holding member 11 away from the detector 1, the push frame 15 is slidably connected to the outer end of the inner side of the guide member 16, the bottom of the positioning frame 18 is clamped to the inner side of the top of the fixing frame 19, and the first elastic telescopic member 110 is in a compressed state;

[0047] When using the device, the staff places the detector 1 inside the distribution cabinet and presses the pressing piece 12. At this time, the pressing piece 12 will slide downward on the upper surface of the holding piece 11. Since the side of the pressing piece 12 close to the upper surface of the holding piece 11 is symmetrically inclined inward, and the upper surface of the pushing piece 13 is squeezed and matched with the inclined surface of the pressing piece 12, as the pressing piece 12 slides downward, it can drive the pushing piece 13 to slide toward the side close to the detector 1, and the bottom of the pushing piece 13 is rotatably connected to the top of the multi-stage telescopic tube 14. As the pushing piece 13 slides on the inner side of the holding piece 11 toward the side close to the detector 1, it will drive the multi-stage telescopic tube 14 to slide at the same time, and when the multi-stage telescopic tube 14 slides inward, it will drive the pushing frame 15 fixedly connected to the inner side of the bottom of the multi-stage telescopic tube 14 to slide at the same time, causing the pushing frame 15 to slide on the inner side of the guide piece 16 toward the center of the bottom plate 17, and when the pushing frame 15 slides inward, the first force storage spring 151 will be moved to the extruded state, and the right The inner side of the bottom of the multi-stage telescopic tube 14 is fixedly connected to the inner side of the positioning frame 18. As the multi-stage telescopic tube 14 moves forward, the positioning frame 18 will be driven to move to the left. When the positioning frame 18 moves to the left, it will be disengaged from the card connection with the top of the fixing frame 19. The first elastic telescopic member 110 in a compressed state will drive the fixing frame 19 to extend outward. At this time, the staff releases their hands, and the first force storage spring 151 in a compressed state will drive the pushing frame 15 to move outward on the inner side of the guide member 16. When the guide member 16 moves outward, it will drive the multi-stage telescopic tube 14 to move outward at the same time. As the multi-stage telescopic tube 14 moves outward, the positioning frame 18 will be prompted to move to the right. At this time, the outer surface of the positioning frame 18 can be attached to the left side of the top of the fixing frame 19. After the fixing frame 19 is extended, the outer surface of the fixing frame 19 can be stuck on the inner side of the distribution cabinet for fixation, so that the detector 1 can be fixed in the distribution cabinet, so that the staff can more accurately insert the connecting wire into the detector 1, thereby improving the accuracy and reliability of wiring.

[0048] refer to Figure 5 and Figure 6 As shown, as mentioned above, the fixing frame 19 can be stretched to the front and rear sides to fix the detector 1 inside the power distribution cabinet. When the staff needs to take the detector 1 out of the power distribution cabinet, the fixing frame 19 needs to be manually pushed inward so that the clamping frame 18 can clamp the top of the fixing frame 19. Only in this way can the detector 1 be taken out from the inside of the power distribution cabinet. Since the outer surface of the fixing frame 19 is attached to the bottom of the inside of the power distribution cabinet, it is difficult for the staff to squeeze the fixing frame 19 inward. If the outer surface of the fixing frame 19 is not separated from the inside of the power distribution cabinet, the detector 1 will be difficult to take out from the inside of the power distribution cabinet. Therefore, the following components are provided to enable the fixing frame 19 to be easily retracted inward:

[0049] When the staff needs to take the detector 1 out of the distribution cabinet, they can pull the pull rope 2 upwards, and the pull rope 2 will move upwards inside the limit sleeve 21 and the drag reduction component 22, and the end of the pull rope 2 close to the drag reduction component 22 is fixedly connected to the inner side of the fixing frame 19. As the pull rope 2 moves upwards, the fixing frame 19 can be pulled. At this time, the fixing frame 19 can slide inward on the upper surface of the bottom plate 17, thereby causing the outer surface of the fixing frame 19 to be separated from the inside of the distribution cabinet. At this time, the staff can easily take the detector 1 out of the distribution cabinet, so that the staff does not need to directly contact the distribution cabinet, thereby reducing the risk of electric shock, and also enabling the staff to quickly evacuate the live area.

[0050] refer to Figures 7 to 10 As shown, when the device is in the initial state, the compression spring 31, the second force storage spring 331 and the pressure spring 35 are all in a naturally relaxed state, and the inner side of the sliding frame 33 is slidably connected to the top of the extrusion frame 32 away from the trigger member 3;

[0051] When the staff places the detector 1 inside the distribution cabinet for wiring, there will be some impurities inside the distribution cabinet. When the detector 1 is placed inside, it is easy to block the wiring hole at the bottom of the detector 1, which affects the staff's wiring of the detector 1. Therefore, the inside of the distribution cabinet should be cleaned first and then the detector 1 is placed. When the detector 1 is placed inside the distribution cabinet, the bottom of the trigger 3 can preferentially contact the inside of the distribution cabinet, and the staff can press the detector 1 downward, and the detector 1 will drive the bottom plate 17 to press downward at the same time. As the bottom plate 17 moves downward, the four corners of the bottom plate 17 will be pressed downward on the outer surface of the trigger 3, and when the bottom plate 17 is pressed downward, the compression spring 31 will be squeezed into a compressed state. Since the outer surface of the bottom of the bottom plate 17 is slidably connected to the inner side of the sliding frame 33, as the bottom plate 17 moves downward, it will drive the sliding frame 33 to move slightly downward at the same time. When the sliding frame 33 moves downward, it will cause the outer surface of the bottom of the sliding frame 33 to face the inside of the cylindrical sleeve 34. When the sliding frame 33 slides toward the two sides of the bottom plate 17, the second force storage spring 331 will be moved to a compressed state, and the sliding frame 33 will also drive the cylindrical sleeve 34 to move at the same time. When the cylindrical sleeve 34 slides toward the left and right ends of the bottom plate 17, the scraping piece 36 fixedly connected to the bottom of the cylindrical sleeve 34 and the rolling piece 37 rotatably connected to the bottom of the cylindrical sleeve 34 will slide at the same time. When the scraping piece 36 slides to both sides, the debris at the bottom of the inner side of the distribution box 30 can be scraped off to the left and right sides, so that the wiring ports at the bottom of the detector 1 are all in a clean state without debris blocking, ensuring that the wiring holes are in good contact, and preventing impurities from clogging the bottom of the detector 1.

[0052] When the staff lifts his hand upward, the compression spring 31 in the compressed state will drive the bottom plate 17 to move upward, and the second force storage spring 331 in the compressed state will drive the sliding frame 33 to slide toward the center of the bottom plate 17. As the sliding frame 33 slides inward on the upper surface of the extrusion frame 32, the cylindrical sleeve 34 will be driven to slide at the same time. When the cylindrical sleeve 34 slides inward, the scraping member 36 and the rolling member 37 at the bottom will be driven to slide at the same time and return to the initial state.

[0053] refer to Fig.11As shown, when the detector 1 is not in use, the staff can push the locking plate 41 downward and wrap the connecting wire around the outer surface of the storage wheel 4. At this time, due to the elasticity of the torsion spring 42, the outer surface of the locking plate 41 can fit the outer surface of the connecting wire. When the staff wraps the connecting wire around the outer surface of the storage wheel 4, the end of the connecting wire can be clamped on the inner side of the limiting member 43, thereby reducing the space occupied by the connecting wire, making the detector 1 more convenient to carry and transport, and the front wire head is clamped inside the limiting member 43 to prevent the connecting wire from being entangled during transportation.

[0054] When the connecting wire needs to be used, it is only necessary to take out the end of the connecting wire from the inside of the limiting member 43 and pull the limiting member 43 outward, and then the connecting wire can be taken out from the outer surface of the storage wheel 4 for easy use.

[0055] refer to Figure 12 to Figure 14As shown, when the detector 1 is placed inside the power distribution cabinet, the sliding rod 54 can be squeezed inwards. At this time, the sliding rod 54 will be squeezed on the inner side and toward the middle of the guide plate 55. As the sliding rod 54 slides inwards, it will drive the second elastic telescopic member 58 fixedly connected to the upper surface of the sliding rod 54. When the second elastic telescopic member 58 moves inwards, it will drive the top moving rod 56 to move at the same time. As the moving rod 56 slides inwards, it will slide backwards on the upper surface of the one-way rack 57. Since the upper surface of the one-way rack 57 is tilted backwards, the moving rod 56 will move upwards when sliding on the upper surface of the one-way rack 57. As the moving rod 56 moves upwards, it will drive the second elastic telescopic member 58 to move inwards. When the sliding rod 54 is pushed outward, the second elastic telescopic member 58 will drive the moving rod 56 to move at the same time, and the moving rod 56 will be stuck by the one-way rack 57 when sliding outward, and the sliding rod 54 will drive the folding lifting frame 53 to move inward at the same time when moving inward. When the folding lifting frame 53 is squeezed inward, the top of the folding lifting frame 53 will move upward. At this time, when the sliding rod 54 is released, the moving rod 56 will be stuck by the one-way rack 57, and the sliding rod 54 will not move outward. , and the folding lifting frame 53 will not move downward, and the top of the folding lifting frame 53 is rotatably connected to the inner side of the sliding member 52, and as the folding lifting frame 53 moves upward, the sliding member 52 is driven to move at the same time, and as the sliding member 52 moves upward, the guide frame 51 slidably connected to the top of the sliding member 52 is driven to move at the same time, and the top of the guide frame 51 is rotatably connected to the bottom of the fixing member 5, and when the guide frame 51 moves upward, it can drive the fixing member 5 to move at the same time, and as the fixing member 5 moves upward, it drives the detector 1 to move upward at the same time through the holding member 11, thereby ensuring that the staff has enough space to install the connecting line at the bottom of the detector 1, and can also avoid To avoid incorrect connection of connecting wires, when the staff needs to adjust the wiring angle of the detector 1, they can rotate the adjusting knob 511 threadedly connected to the outer surface of the fixing part 5, causing the adjusting knob 511 to move outward on the inner side of the fixing part 5. As the adjusting knob 511 moves outward, the left side of the adjusting knob 511 will disengage from the circular hole on the outer side of the guide frame 51. At this time, the staff can adjust the angle of the fixing part 5, and the fixing part 5 drives the detector 1 to rotate at the same time through the holding part 11, so that the detector 1 can be adjusted at multiple angles, so that the detector 1 can better adapt to different environments and conditions, ensuring that the detection work can be carried out smoothly in various distribution cabinets.

[0056] When the angle of the detector 1 is adjusted, the adjusting knob 511 can be rotated in the opposite direction to cause the adjusting knob 511 to move to the left and re-engage in the circular hole on the outside of the adjusting knob 511, so that the angle of the detector 1 can be fixed. When the detector 1 needs to move downward, the staff can pull the second elastic telescopic member 58 upward. As the second elastic telescopic member 58 moves upward, it will drive the moving rod 56 to move at the same time. At this time, the outer surface of the moving rod 56 will be disengaged from the one-way rack 57. At this time, the sliding rod 54 will drive the folding lifting frame 53 to slide outward, and when the folding lifting frame 53 slides outward, it will drive the guide frame 51 to move downward through the sliding member 52. As the guide frame 51 moves downward, it will drive the holding member 11 and the detector 1 to move downward at the same time through the fixing member 5 for reset.
