Description

Technical Field

[0001] The present invention relates to the technical field of substation operation and maintenance, and specifically provides a portable substation operation and maintenance auxiliary terminal system. Background Technique

[0002] Substation operation and maintenance is an important link in the operation and management of the power system. The main work contents of substation operation and maintenance include: equipment inspection, equipment maintenance, switching operation, fault handling and safety management. Among them, equipment inspection refers to regularly inspecting electrical equipment such as transformers, circuit breakers, disconnectors, instrument transformers, and busbars in the substation, checking for abnormal phenomena such as damage, oil leakage, and discharge on the appearance of the equipment, and recording parameters such as the operating temperature, pressure, voltage, and current of the equipment, which can effectively ensure the normal and safe operation of various electrical equipment.

[0003] Currently, the inspection system for substations usually installs a pan-tilt camera on the top of a vertical pole to monitor the opening and closing of the substation switchgear and the appearance of electrical equipment. Macro-instrument cameras are installed in front of multiple ammeters and voltmeters to irradiate the current and voltage parameters of the ammeters and voltmeters in the substation. The pan-tilt camera and the macro-instrument camera form an automatic inspection system for the substation with the supervision background. However, due to the large floor area of the substation and the complex installation structure of each electrical equipment, when the pan-tilt camera obtains an image, the front-side equipment is likely to block the rear-side equipment, and the height of the pan-tilt camera is fixed and cannot be changed. There are too many detection dead spots in the inspection by installing the pan-tilt camera at a fixed point, and there is a lack of a terminal that can walk in the substation and switch positions on multiple vertical poles for multi-point inspection.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This portable substation operation and maintenance auxiliary terminal system is equipped with an upper climbing frame and a lower climbing frame. The air pump inflates the airbag through the air pipe. When the airbag inflates and expands, it pushes the clamping block out of the rectangular groove, causing the clamping block to squeeze the outer wall of the vertical rod. By borrowing the frictional force generated by the clamping block squeezing the vertical rod, the lower climbing frame and the vertical rod remain relatively stationary. At the same time, the electric telescopic rod extends, and the upper climbing frame is subjected to the reverse force of the electric telescopic rod and moves upward on the vertical rod relative to the lower climbing frame. Then, the air pump is switched to drive the clamping blocks in the upper climbing frame and the lower climbing frame to clamp, and in cooperation with the telescopic movement of the electric telescopic rod, the upper climbing frame and the lower climbing frame automatically climb to the top of the vertical rod, and the height of the pan-tilt camera can be adjusted arbitrarily, changing the existing method of fixing the pan-tilt camera with bolts at fixed points. In addition, after the electric telescopic rod contracts, it pulls the upper climbing frame downward, and the upper climbing frame and the lower climbing frame approach each other, reducing the overall volume of the device, facilitating holding through the lower fixing ring and the upper fixing ring, and making the device easy to carry.

[0016] 2. This portable substation operation and maintenance auxiliary terminal system is equipped with a U-shaped frame. When the U-shaped frame is placed on the ground, the first motor is started to drive the wheel shaft to rotate, and the wheel shaft drives the two rear wheels to rotate. In cooperation with the two front wheels, the U-shaped frame is driven to move forward. By the rear-drive method, after the U-shaped frame comes down from the vertical rod, it can carry the upper climbing frame and the lower climbing frame and walk stably on the substation ground, completing the two-dimensional walking function and achieving the effect of moving within the substation for full-range inspection.

[0017] 3. This portable substation operation and maintenance auxiliary terminal system is equipped with a toothed arc plate and a connecting plate. The second motor drives the driving gear to rotate, and the driving gear drives the toothed arc plate to move in the arc groove. The toothed arc plate drives the T-shaped block to rotate around the center of the lower climbing frame through the connecting plate. The T-shaped block drives the vertical plate to move through the T-shaped groove, and the vertical plate drives the pan-tilt camera to move through the L-shaped plate, and it can move along a semi-circular path outside the upper climbing frame. At the same time, the third motor drives the pan-tilt camera to rotate 360 degrees in the vertical direction. In cooperation with the lifting and lowering of the upper climbing frame and the lower climbing frame on the vertical rod, the image acquisition range of the pan-tilt camera can be greatly improved, and the image acquisition dead angle can be reduced.

[0018] 4. This portable substation operation and maintenance auxiliary terminal system is equipped with a lower movable ring and an upper movable ring. By dialing the upper movable ring outward, the upper movable ring drives the connecting block to rotate relative to the slider through the spindle, causing the upper movable ring to rotate relative to the upper fixing ring. At the same time, the upper movable ring drives the lower movable ring to rotate relative to the fixed seat through the electric telescopic rod, thereby enabling the upper climbing frame and the lower climbing frame to be quickly installed and disassembled on the vertical rod, achieving the effect of rapid disassembly and assembly of the device, and avoiding the trouble of manually climbing to the top of the vertical rod for manual disassembly and assembly of the traditional pan-tilt camera.

[0024] As Figures 1 to 7 shown, the portable substation operation and maintenance auxiliary terminal system of this embodiment includes a U-shaped frame 1. The U-shaped frame 1 is in a U shape. A fixed seat 2 is vertically connected to the upper surface of the U-shaped frame 1 near the rear side edge. A lower climbing frame 3 is installed on the front side of the fixed seat 2. An upper climbing frame 4 is installed on the front side of the fixed seat 2 above the lower climbing frame 3. The upper climbing frame 4 and the lower climbing frame 3 alternately clamp the vertical pole and cooperate with the telescopic movement of the electric telescopic rod 411 to achieve the effect of automatically climbing to the vertical pole for image acquisition. A lower moving slot 21 is opened on the front side wall of the fixed seat 2 to provide space for the rotation of the moving block 14 connected to the lower moving ring 32. A sliding slot 22 is opened inside the fixed seat 2 above the lower moving slot 21. A slider 23 is slidably connected inside the sliding slot 22. The slider 23 can slide up and down in the sliding slot 22 to adapt to the lifting of the upper climbing frame 4 relative to the fixed seat 2 during the climbing process. An upper moving slot 24 is opened inside the slider 23 to provide space for the rotation of the moving block 14 connected to the upper moving ring 42; The lower climbing frame 3 includes a lower fixed ring 31 installed on the front side wall of the fixed seat 2. A lower moving ring 32 is provided on one side of the lower fixed ring 31. The bottom of the lower fixed ring 31 is fixedly connected to the U-shaped frame 1. The lower moving ring 32 is movably connected to the U-shaped frame 1; The upper climbing frame 4 includes an upper fixed ring 41 installed on the front side wall of the slider 23. An upper moving ring 42 is provided on one side of the upper fixed ring 41. The upper fixed ring 41, the upper moving ring 42, the lower fixed ring 31, and the lower moving ring 32 are coaxially arranged. And electric telescopic rods 411 are installed through the inside of both the upper fixed ring 41 and the upper moving ring 42. The electric telescopic rods 411 are electrically connected to the control system 27 through a circuit; The inner walls of the upper fixed ring 41, the upper movable ring 42, the lower fixed ring 31 and the lower movable ring 32 are all provided with grooves 8. Rollers 9 are installed inside the grooves 8. During the climbing process of the upper climbing frame 4 and the lower climbing frame 3 on the vertical pole, the rollers 9 contact the outer wall of the vertical pole and roll relative to the vertical pole, reducing the friction during the movement of the upper climbing frame 4 and the lower climbing frame 3. Rectangular grooves 10 are opened on the inner walls of the upper fixed ring 41, the upper movable ring 42, the lower fixed ring 31 and the lower movable ring 32 on one side of the groove 8. Air bags 11 are installed inside the rectangular grooves 10. The air bags 11 are inflated and expanded and deflated and compressed. A clamping block 12 is connected to one side of the air bag 11. A ventilation pipe 13 is connected to the top of the air bag 11. Movable blocks 14 are integrally connected to the front side walls of the upper movable ring 42 and the lower movable ring 32. The two movable blocks 14 are respectively inserted into the upper movable groove 24 and the lower movable groove 21 and are provided with a pin shaft 15 passing through. A torsion spring is sleeved outside the pin shaft 15 for driving the movable block 14 to reset.

[0025] Specifically, the upper fixed ring 41, the upper movable ring 42, the lower fixed ring 31 and the lower movable ring 32 are all in a semi-circular ring shape. The lower fixed ring 31 and the upper fixed ring 41 are respectively combined with the lower movable ring 32 and the upper movable ring 42 to form a ring shape. The inner diameter dimensions of the upper fixed ring 41, the upper movable ring 42, the lower fixed ring 31 and the lower movable ring 32 are adapted to the outer diameter dimensions of the vertical poles in the substation. The vertical poles for the device to climb can be installed at specific positions in the substation or can be the vertical poles for installing electrical equipment. The sizes of the upper climbing frame 4 and the lower climbing frame 3 are customized according to the pre-measured outer diameter dimensions of the vertical poles. The upper movable ring 42 and the lower movable ring 32 are respectively rotationally connected to the slider 23 and the fixed seat 2 through the pin shaft 15. The upper movable ring 42 and the lower movable ring 32 can respectively rotate relative to the upper fixed ring 41 and the lower fixed ring 31, enabling the upper climbing frame 4 and the lower climbing frame 3 to be disassembled and assembled on the vertical pole. The number of the electric telescopic rods 411 is eight, and they are arranged at equal circumferential intervals on the upper fixed ring 41 and the upper movable ring 42. The telescopic ends at the bottoms of the electric telescopic rods 411 are connected to the upper surfaces of the lower fixed ring 31 and the lower movable ring 32. When the climbing frame and the vertical pole are kept relatively stationary under the action of the clamping block 12, by the elongation of the electric telescopic rods 411, the upper climbing frame 4 is subjected to the reverse acting force of the electric telescopic rods 411 and moves upward on the vertical pole relative to the lower climbing frame 3. By switching the inflation by the air pump 28 and cooperating with the telescopic movement of the electric telescopic rods 411, the upper climbing frame 4 and the lower climbing frame 3 can automatically climb to the top of the vertical pole, enabling the device to not only walk horizontally on the ground but also walk in the vertical direction.

[0026] Further, the inner wall of the clamping block 12 is provided with anti-slip lines for anti-slip between the clamping block 12 and the outer wall of the vertical rod. The width dimension of the clamping block 12 is adapted to the width dimension of the inner wall of the rectangular groove 10. The clamping block 12 is slidably connected to the rectangular groove 10. The roller 9 is rotatably connected to the upper fixed ring 41, the upper movable ring 42, the lower fixed ring 31, and the lower movable ring 32. The air pump 28 inflates the airbag 11 through the ventilation pipe 13. The inflated airbag 11 pushes the clamping block 12 to extend out of the rectangular groove 10, so that the clamping block 12 presses against the outer wall of the vertical rod. The frictional force generated by the clamping block 12 pressing against the vertical rod is used to keep the lower climbing frame 3 stationary relative to the vertical rod.

[0027] Further, two front wheels 101 are installed at the bottom of the U-shaped frame 1 near the front side edge, and two rear wheels 102 are installed at the bottom of the U-shaped frame 1 near the rear side edge. A wheel axle 103 is connected between the two rear wheels 102. The two rear wheels 102 are rotatably connected to the U-shaped frame 1 via the wheel axle 103. According to actual applications, an existing wheel steering system can also be installed on the rear wheels 102 for the U-shaped frame 1 to walk and turn. A secondary gear 104 is sleeved in the middle of the wheel axle 103. A main gear 105 is meshed and connected above the secondary gear 104. One side of the main gear 105 is connected with a first motor 106. The first motor 106 is installed inside the U-shaped frame 1. A laser distance sensor 107 is embedded and installed at the bottom of the U-shaped frame 1. The number of the front wheels 101 and the rear wheels 102 is two each, and the two front wheels 101 and the two rear wheels 102 are symmetrically arranged relative to the U-shaped frame 1. The front wheels 101 and the rear wheels 102 are both rotatably connected to the U-shaped frame 1. By starting the first motor 106 to drive the wheel axle 103 to rotate, the wheel axle 103 drives the two rear wheels 102 to rotate, and together with the two front wheels 101, it drives the U-shaped frame 1 to move forward. By means of rear-wheel drive, after the U-shaped frame 1 comes down from the vertical rod, it can carry the upper climbing frame 4 and the lower climbing frame 3 to walk stably on the substation ground.

[0028] Further, the rear side wall of the fixed seat 2 is vertically connected with a mounting plate 25. A mobile power source 26 is installed on the upper surface of the mounting plate 25 to provide power for the device. A control system 27 is installed on the upper surface of the mobile power source 26. The control system 27 includes a processor and a remote control for inputting instructions. The remote control communicates remotely with the processor for remote control. An air pump 28 is installed on the upper surface of the mounting plate 25 on one side of the mobile power source 26. The air outlet of the air pump 28 is connected to the ventilation pipe 13, and the air inlet of the air pump 28 is communicated with the external environment. The ventilation pipes 13 on the upper climbing frame 4 and the lower climbing frame 3 are connected to the air pump 28 in a converging manner, and a solenoid valve is installed at the converging place, which is used to control the switching of the ventilation pipes 13 in the upper climbing frame 4 and the lower climbing frame 3 for inflation and also to control the exhaust of the ventilation pipe 13. The laser distance sensor 107 is electrically connected to the control system 27 through a circuit. When the upper climbing frame 4 and the lower climbing frame 3 descend to the ground along the vertical rod, the distance from the U-shaped frame 1 to the ground is detected by the laser distance sensor 107 to achieve automatic landing.

[0029] Furthermore, arc-shaped grooves 33 are formed in the outer sidewalls of the lower fixed ring 31 and the lower movable ring 32. A toothed arc-shaped plate 34 is slidably connected in the arc-shaped groove 33 in the lower fixed ring 31. When the toothed arc-shaped plate 34 moves in the arc-shaped groove 33, it rotates around the center of the lower climbing frame 3. When the toothed arc-shaped plate 34 moves in the lower fixed ring 31, the side away from the connecting plate 37 will insert into the arc-shaped groove 33 of the lower movable ring 32. One side of the toothed arc-shaped plate 34 is meshed with a driving gear 35. A second motor 36 is installed inside the U-shaped frame 1 below the driving gear 35. The upper surface of one side of the toothed arc-shaped plate 34 protrudes from above the lower fixed ring 31 and is vertically connected with a connecting plate 37. A T-shaped block 38 is connected to the sidewall of the connecting plate 37. The top of the arc-shaped groove 33 protrudes from the upper surfaces of the lower fixed ring 31 and the lower movable ring 32. The toothed arc-shaped plate 34 is in the shape of an arc-shaped plate. The toothed arc-shaped plate 34 is slidably connected to the lower fixed plate and the lower movable plate through the arc-shaped groove 33. The second motor 36 drives the driving gear 35 to rotate, and the driving gear 35 drives the toothed arc-shaped plate 34 to move in the arc-shaped groove 33.

[0030] Furthermore, a card slot 43 is formed in the outer sidewall of the upper fixed ring 41. A card block 44 is slidably connected inside the card slot 43. An L-shaped plate 45 is connected to the sidewall of the card block 44 for installing a third motor 46. The third motor 46 is installed on the upper surface of the L-shaped plate 45. The shaft end of the third motor 46 is connected with a pan-tilt camera 47. The third motor 46 rotates to drive the pan-tilt camera 47 to rotate in a full circle. A fill light 48 is installed on the upper surface of the pan-tilt camera 47 for filling light for the image collected by the pan-tilt camera 47. The bottom of the L-shaped plate 45 is vertically connected with a vertical plate 49. A T-shaped groove 410 is formed on the side of the vertical plate 49 close to the upper fixed ring 41.

[0031] Furthermore, the card slot 43 is in the shape of an arc with a T-shaped cross-section. The sidewall of the L-shaped plate 45 is slidably connected to the upper fixed ring 41 through the card block 44. When the toothed arc-shaped plate 34 moves in the arc-shaped groove 33, it supports and drives the L-shaped plate 45 to rotate along the same trajectory. The bottom of the L-shaped plate 45 is connected to the vertical plate 49. The pan-tilt camera 47 and the fill light 48 are rotationally connected to the L-shaped plate 45 through the third motor 46.

[0032] Furthermore, the bottom of the connecting plate 37 is connected to the toothed arc-shaped plate 34. The cross-sections of the T-shaped block 38 and the T-shaped groove 410 are both in the shape of a T. The T-shaped block 38 is clamped inside the T-shaped groove 410 and slides up and down. The sidewall of the connecting plate 37 is connected to the vertical plate 49 through the T-shaped block 38. When the toothed arc-shaped plate 34 moves in the arc-shaped groove 33, the toothed arc-shaped plate 34 drives the T-shaped block 38 to rotate around the center of the lower climbing frame 3 through the connecting plate 37. The T-shaped block 38 drives the vertical plate 49 to move through the T-shaped groove 410. The vertical plate 49 drives the pan-tilt camera 47 to move through the L-shaped plate 45, and it can move along a semi-circular path outside the upper climbing frame 4.

[0033] Further, insertion blocks 5 are integrally connected to the side walls of the upper movable ring 42 and the lower movable ring 32. A limiting slot 6 is formed through the middle of the insertion block 5. Slots corresponding to the width dimensions of the insertion blocks 5 are formed in the upper fixing ring 41 and the lower fixing ring 31 near the insertion blocks 5. Electromagnets 7 are installed on the upper surfaces of the upper fixing ring 41 and the lower fixing ring 31 above the slots. The upper movable ring 42 and the lower movable ring 32 are movably inserted into the upper fixing ring 41 and the lower fixing ring 31 through the insertion blocks 5 respectively. The movable ends of the electromagnets 7 are movably inserted into the limiting slots 6. The electromagnets 7 are of the push-pull type. When energized, the movable ends contract. When de-energized, the movable ends extend and are inserted into the limiting slots 6 to lock and close the insertion blocks 5. The upper climbing frame 4 and the lower climbing frame 3 are stably closed by the locking of the electromagnets 7.

[0034] The usage method of this embodiment is as follows: When the user actually uses the substation operation and maintenance auxiliary terminal to conduct inspections in the substation, first place the U-shaped frame 1 on the ground, control the first motor 106 to start through the control system 27. The start of the first motor 106 drives the wheel shaft 103 to rotate, and the wheel shaft 103 drives the two rear wheels 102 to rotate. Cooperating with the two front wheels 101, the U-shaped frame 1 is driven to move forward, enabling the U-shaped frame 1 to carry the upper climbing frame 4 and the lower climbing frame 3 to stably walk on the substation ground. At the same time, the second motor 36 drives the driving gear 35 to rotate, and the driving gear 35 drives the toothed arc plate 34 to move in the arc groove 33. The toothed arc plate 34 drives the T-shaped block 38 to rotate around the center of the lower climbing frame 3 through the connecting plate 37. The T-shaped block 38 drives the vertical plate 49 to move through the T-shaped groove 410. The vertical plate 49 drives the pan-tilt camera 47 to move through the L-shaped plate 45, and it can move along a semi-circular path outside the upper climbing frame 4. At the same time, the third motor 46 drives the pan-tilt camera 47 to rotate 360 degrees in the vertical direction, enabling the pan-tilt camera 47 to collect images of the substation from multiple angles, irradiate the opening and closing conditions of the substation circuit breakers and the appearance of electrical equipment, and transmit the image data to the supervision background. Since the ground height is too low to observe the electrical equipment installed at high places, the U-shaped frame 1 is controlled to move to the vertical pole. By dialing the upper movable ring 42 outward, the upper movable ring 42 drives the connecting block to rotate relative to the slider 23 through the spindle 15, enabling the upper movable ring 42 to rotate relative to the upper fixed ring 41. At the same time, the upper movable ring 42 drives the lower movable ring 32 to rotate relative to the fixed seat 2 through the electric telescopic rod 411, and then the upper climbing frame 4 and the lower climbing frame 3 are opened and installed on the vertical pole. At this time, the rollers 9 are in contact with the outer wall of the vertical pole. Then, dial the upper movable ring 42 to rotate back to its original position, and the insert block 5 on the upper movable ring 42 is inserted into the slot in the upper fixed ring 41. Control the electromagnet 7 to cut off the power and extend, and the movable end of the electromagnet 7 is inserted into the limit slot 6(6) to limit the insert block 5, so that the upper movable ring 42 and the lower movable ring 32 are respectively locked and closed with the upper fixed ring 41 and the lower fixed ring 31. Then start the air pump 28, and the air pump 28 inflates the airbag 11 through the air pipe 13 inside the lower climbing frame 3. The inflated airbag 11 pushes the clamping block 12 to extend from the rectangular groove 10, so that the clamping block 12 presses against the outer wall of the vertical pole, and the friction force generated by the clamping block 12 pressing against the vertical pole is used to keep the lower climbing frame 3 relatively stationary with respect to the vertical pole. Then the electric telescopic rod 411 extends, and the upper climbing frame 4 is subjected to the reverse force of the electric telescopic rod 411 and moves upward on the vertical pole relative to the lower climbing frame 3. Then control the air pump 28 to inflate the air pipe 13 inside the upper climbing frame 4 to clamp the clamping block 12 inside the upper climbing frame 4. Then control the airbag 11 inside the lower climbing frame 3 to deflate, and cooperate with the contraction of the electric telescopic rod 411, so that the electric telescopic rod 411 pulls the lower climbing frame 3 upward to approach the upper climbing frame 4. Then repeat the above operations multiple times, so that the upper climbing frame 4 and the lower climbing frame 3 drive the U-shaped frame 1 to move upward on the vertical pole, enabling the upper climbing frame 4 to drive the pan-tilt camera 47 to rise and collect height images, and the height of the pan-tilt camera 47 can be adjusted arbitrarily to reduce the image collection dead angle.
