Description

Technical Field

[0001] This invention relates to the field of substation ranging technology, specifically to an intelligent three-dimensional safe distance ranging device for substations. Background Technology

[0002] A substation is a place in a power system that transforms voltage and current, receives electrical energy, and distributes electrical energy. Substations in power plants are step-up substations, whose function is to step up the electrical energy generated by the generator and feed it into the high-voltage power grid. There are several dangerous areas in a substation, and a three-dimensional positioning system is formed using base stations to demarcate danger fences in dangerous areas of the substation. Distance measuring devices are usually needed to measure the distance between safe and dangerous areas.

[0003] When personnel enter a substation, they need to wear positioning badges to indicate their three-dimensional location within the substation. However, traditional ranging devices are not convenient for measuring distances between safe and hazardous areas using the location provided by the badges. This results in a complex structure for traditional ranging devices, which are also not easy to stabilize after being moved, potentially leading to errors in the ranging data. Furthermore, traditional ranging devices may generate static electricity when operating in a substation, which could pose a danger if personnel come into contact with them.

[0004] To address the aforementioned issues, an intelligent three-dimensional safety distance measuring device for substations is proposed. Summary of the Invention

The improved measuring device facilitates the measurement of safe and dangerous areas using the position provided by the positioning badge. The improved measuring device has a simpler structure, is easier to stabilize after movement, and the measuring data is error-free. When the improved measuring device is working in the substation, it does not generate static electricity, and there is no danger when personnel come into contact with it, thus solving the problems in the background art.

Through strip grooves are opened through the four corners inside the supporting chassis, and the through strip grooves are not on the same vertical line as the traveling wheel. A second connecting shaft is also provided inside the supporting chassis.

[0011] Furthermore, the second connecting shaft includes a first linkage wheel disposed on the outer side of one end, and a second linkage wheel is engaged on one side of the first linkage wheel. The second linkage wheel is connected to a third linkage wheel via a shaft, the third linkage wheel is connected to a fourth linkage wheel via a shaft, and the fourth linkage wheel is connected to a fifth linkage wheel via a shaft.

[0012] Furthermore, the lifting platform includes a fitting block disposed at the lower end of the lifting platform and a lifting frame disposed at the lower end of the fitting block, with one end of the lifting frame disposed inside the component groove. The lifting platform also includes a lifting column disposed at the lower end of the fitting block, with the lifting column fitted inside the lifting bar groove. One end of the lifting column meshes with the fifth linkage wheel, and the position of the lifting column is inside the lifting frame.

[0013] Furthermore, the drive box includes a first motor disposed at the upper part inside the drive box and a drive wheel and lifting assembly disposed at one end of the first motor.

[0014] Furthermore, the lifting assembly includes a rotating shaft and a pulley disposed on the outside of the rotating shaft. The lifting assembly also includes a threaded post disposed at one end of the rotating shaft, a lifting block being threaded on the outside of the threaded post, a support post being disposed at the lower end of one side of the lifting block, and one end of the support post being fitted into the through groove.

[0015] Furthermore, a drive belt is arranged around the outside of the pulley, the drive belt is wrapped around the inside of the four sets of drive boxes, and the drive belt is arranged inside the connecting strip.

[0016] Furthermore, the length of the transmission slot is equal to the length of the positioning badge. The QR code recognition component is used to recognize the QR code. The QR code recognition component is electrically connected to the ranging module. The supporting chassis, lifting platform, ranging box and drive box are all equipped with insulating shells.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention provides an intelligent three-dimensional safety distance measuring device for substations. When three-dimensional safety distance measurement is required in a substation, personnel wearing positioning badges pull the device into the substation, place the device at the location to be measured, and take out the positioning badge to fit into the transmission groove. The positioning badge is then transported into the transmission groove by two sets of transmission belts. At this time, the QR code recognition component is positioned directly above the QR code, and the distance measuring module is positioned directly above the pulse module. When the QR code recognition component recognizes the QR code as the correct personnel QR code, the distance measuring module starts working, emitting pulses to measure the distance to the danger zone. The distance can be measured, and the distance can be moved to the critical point of the safe area in the base station's three-dimensional positioning system according to the positioning badge. At this position, the distance to the dangerous area can be measured. The position of the ranging module can be changed according to the actual situation to measure the distance between the actual location and the dangerous area. The fifth linkage wheel can be driven to rotate as needed. Since the fifth linkage wheel is engaged with the lifting column, the lifting column can be raised and lowered. Since one end of the lifting column is connected to the lower end of the interlocking block, the raising and lowering of the lifting column can drive the raising and lowering of the lifting platform and the ranging box, thereby changing the ranging height of the ranging module. Since one end of the lifting frame is set inside the component slot and the other end is set at the lower end of the interlocking block, the raising and lowering of the lifting platform is stabilized.

[0019] 2. The present invention provides an intelligent three-dimensional safety distance measuring device for substations. Because the lower end of the supporting chassis is equipped with four sets of wheels, the device can be moved via these wheels, facilitating distance measurement at multiple locations. When the device reaches a designated position for distance measurement, the first motor drives the rotating shaft and threaded column to rotate. Since the threaded column is threadedly connected inside the lifting block, its rotation causes the lifting block and support column to rise and fall. When the support column descends to a certain position, it contacts the ground. Only one of the four drive boxes contains a lifting assembly, a driving wheel, a first driven wheel, a second driven wheel, a third driven wheel, a first connecting shaft, and a first electric motor. The other three groups are only equipped with lifting components. When the pulley of one group rotates, the support columns inside the four drive boxes all descend under the action of the transmission belt, thereby supporting the entire device and preventing the traveling wheels from contacting the ground. This stabilizes the entire device and prevents it from shifting or shaking. The rotation of the drive wheel will drive the first driven wheel, the second driven wheel, the third driven wheel and the first connecting shaft to rotate. Since the first connecting shaft is connected to the second connecting shaft, the first linkage wheel, the second linkage wheel, the third linkage wheel, the fourth linkage wheel and the fifth linkage wheel will all rotate. A linkage structure for the lifting of the jacking column and the lifting of the support column is set up to reduce energy consumption.

[0020] 3. The present invention provides an intelligent three-dimensional safe distance measuring device for substations. When the device is in operation, due to the substation environment, the entire device may become contaminated with static electricity. Insulating shells are provided for the supporting chassis, lifting platform, distance measuring box, and drive box to reduce the damage of static electricity to personnel. When the device is working, the second motor drives the third transmission wheel to rotate, so that the fan can blow away the charge generated inside the ion fan chamber. Due to the rotation of the third transmission wheel, the second transmission wheel, the first transmission wheel, the third gear, the first gear, and the second gear can be rotated. At this time, the lifting door is driven to rise, so that the air blown by the fan can carry the charge and blow it towards the flow equalization plate. The flow equalization plate has evenly distributed through holes, so that the air can be evenly blown into the distance measuring box to eliminate static electricity. When the device is not working, the second motor drives the third transmission wheel to rotate. At this time, the fan absorbs the heat inside the distance measuring box and dissipates it through the ventilation mesh, and the lifting door slowly descends. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To address the technical problem that traditional ranging devices are inconvenient for using the location information provided by positioning badges to measure distances between safe and hazardous areas, such as... Figure 1-2 and Figure 5-7 As shown, the following preferred technical solutions are provided:

[0032] An intelligent three-dimensional safety distance measuring device for substations includes a support chassis 1, a lifting platform 2 and a drive box 4 mounted on the upper end of the support chassis 1, a distance measuring box 3 mounted on the upper end of the lifting platform 2, and four sets of drive boxes 4. Each distance measuring box 3 includes a transmission groove 31 formed on one side of the distance measuring box 3 and transmission belts 32 mounted on the upper and lower ends of the inner wall of the transmission groove 31. The distance measuring box 3 also includes a positioning badge 33 fitted inside the transmission groove 31 and an ion fan cavity 36 located at one end of the distance measuring box 3. A measuring device is also provided at the upper end of the transmission groove 31. The ion fan cavity 36 contains a gear assembly 37 located at the upper end of module 35 and QR code recognition component 34. Positioning badge 33 includes a pulse module 331 inside the badge and a QR code label 332 on the upper side of the badge. The supporting chassis 1 includes a traveling wheel 11 at the lower end and a component groove 12 on the upper end of the traveling wheel 11. The supporting chassis 1 also includes a connecting strip 13 on the upper end and a lifting strip groove 14 inside the chassis 1. Four sets of connecting strips 13 are provided, and the connecting strips 13 of one set are connected to the drive boxes 4 of two sets. Through slots 15 are provided through the four corners inside the bearing chassis 1, and the through slots 15 and the traveling wheels 11 are not on the same vertical line. A second connecting shaft 16 is also provided inside the bearing chassis 1. The second connecting shaft 16 includes a first linkage wheel 161 provided on the outer side of one end, and a second linkage wheel 162 is engaged on one side of the first linkage wheel 161. The second linkage wheel 162 is connected to a third linkage wheel 163 through a shaft. A fourth linkage wheel 164 is connected via a shaft, and a fifth linkage wheel 165 is connected via a shaft to the fourth linkage wheel 164. The lifting platform 2 includes a fitting block 21 disposed at the lower end of the lifting platform 2 and a lifting frame 22 disposed at the lower end of the fitting block 21. One end of the lifting frame 22 is disposed inside the component groove 12. The lifting platform 2 also includes a lifting column 23 disposed at the lower end of the fitting block 21. The lifting column 23 is fitted inside the lifting bar groove 14. One end of the lifting column 23 meshes with the fifth linkage wheel 165. The position of the lifting column 23 is inside the lifting frame 22.

[0033] Specifically, when three-dimensional safety distance measurement is required in a substation, personnel wearing positioning badges 33 pull the device into the substation, place the device at the location to be measured, and take out the positioning badge 33 to fit it into the transmission groove 31. The positioning badge 33 is then transported into the transmission groove 31 via two sets of transmission belts 32. At this time, the QR code recognition component 34 is positioned directly above the QR code identifier 332, and the distance measuring module 35 is positioned directly above the pulse module 331. When the QR code recognition component 34 recognizes the QR code identifier 332 as the correct personnel QR code, the distance measuring module 35 starts working, emitting pulses to measure the distance to the danger zone. It can also move to the safety zone boundary point in the base station's three-dimensional positioning system based on the positioning badge 33, and measure the distance at this location. The distance to the danger zone can be measured by changing the position of the ranging module 35 according to the actual situation. The fifth linkage wheel 165 can be driven to rotate as needed. Since the fifth linkage wheel 165 is engaged with the lifting column 23, the lifting column 23 can be raised and lowered. Since one end of the lifting column 23 is connected to the lower end of the fitting block 21, the raising and lowering of the lifting column 23 can drive the raising and lowering of the lifting platform 2 and the ranging box 3, thereby changing the ranging height of the ranging module 35. Since one end of the lifting frame 22 is set inside the component groove 12 and the other end is set at the lower end of the fitting block 21, the raising and lowering of the lifting platform 2 is stabilized. The length of the transmission groove 31 is equal to the length of the positioning badge 33. The QR code recognition component 34 is used to recognize the QR code and is electrically connected to the ranging module 35.

[0034] To address the technical problem of traditional distance measuring devices being difficult to stabilize after movement, which could lead to errors in distance measurement data, such as... Figure 2-4 As shown, the following preferred technical solutions are provided:

[0035] The drive box 4 includes a first motor 47 disposed at the upper end of the drive box 4, a drive wheel 42 disposed at one end of the first motor 47, and a lifting assembly 41. The drive box 4 also includes a first driven wheel 43 meshing with one side of the drive wheel 42. A second driven wheel 44 is connected to one side of the first driven wheel 43 via a shaft. A third driven wheel 45 is connected to one side of the second driven wheel 44 via a shaft. A first connecting shaft 46 is disposed at one end of the third driven wheel 45. One end of the first connecting shaft 46 is connected to the second connecting shaft 46. The lifting assembly 41 includes a rotating shaft 411 and a lifting assembly 41. The lifting assembly 41 also includes a threaded post 414 at one end of the rotating shaft 411, a lifting block 413 threaded on the outside of the threaded post 414, a support post 415 at the lower end of one side of the lifting block 413, and one end of the support post 415 is fitted into the through groove 15. One end of the rotating shaft 411 is connected to the first motor 47. A transmission belt 48 is arranged around the outside of the pulley 412. The transmission belt 48 is arranged inside the four sets of drive boxes 4 and is located inside the connecting strip 13.

[0036] Specifically, because the lower end of the supporting chassis 1 is equipped with traveling wheels 11, the device can be moved by four sets of traveling wheels 11, which facilitates distance measurement at multiple positions. When the device reaches the designated position for distance measurement, the first motor 47 drives the rotating shaft 411 and the threaded column 414 to rotate. Since the threaded column 414 is threadedly connected inside the lifting block 413, the rotation of the threaded column 414 will cause the lifting block 413 and the support column 415 to rise and fall. When the support column 415 descends to a certain position, it will contact the ground. Only one of the four sets of drive boxes 4 is equipped with a lifting assembly 41, a driving wheel 42, a first driven wheel 43, a second driven wheel 44, a third driven wheel 45, a first connecting shaft 46, and a first motor 47. The other three sets are only equipped with... The device is equipped with a lifting assembly 41. When one set of pulleys 412 rotates, the support columns 415 inside the four sets of drive boxes 4 all descend under the action of the transmission belt 48, thereby supporting the entire device and preventing the walking wheels 11 from contacting the ground. This stabilizes the entire device and prevents it from shifting or shaking. The rotation of the drive wheel 42 will drive the first driven wheel 43, the second driven wheel 44, the third driven wheel 45 and the first connecting shaft 46 to rotate. Since the first connecting shaft 46 is connected to the second connecting shaft 16, the first linkage wheel 161, the second linkage wheel 162, the third linkage wheel 163, the fourth linkage wheel 164 and the fifth linkage wheel 165 will all rotate. A linkage structure is set up for the lifting of the lifting column 23 and the lifting of the support column 415.

[0037] To address the technical problem that traditional ranging devices may generate static electricity when operating in substations, posing a danger to personnel upon contact, such as... Figure 7-8 As shown, the following preferred technical solutions are provided:

[0038] The supporting chassis 1, lifting platform 2, distance measuring box 3, and drive box 4 are all equipped with insulating shells. The ion fan cavity 36 includes a lifting door 361 movably disposed inside the ion fan cavity 36 and a first transmission wheel 362 disposed at the upper end of the ion fan cavity 36. A second transmission wheel 363 is meshed at one end of the first transmission wheel 362. Two sets of second transmission wheels 363 are provided, and the two sets of second transmission wheels 363 are connected by a shaft. A third transmission wheel 365 is meshed at the lower end of one set of second transmission wheels 363. The ion fan cavity 36 also includes a second motor 364 disposed at one end inside the ion fan cavity 36 and a transparent... The air network 366 and the third transmission wheel 365 are located on the outer side of one end of the second motor 364. A fan 367 is also provided at one end of the second motor 364. A flow equalization plate 368 is provided on one side of the ion fan cavity 36 and is located inside the distance measuring box 3. The gear assembly 37 includes a second gear 372 meshing on one side of the lifting door 361 and a first gear 371 connected to one side of the second gear 372 via a shaft. A third gear 373 is meshed on one side of the first gear 371. The lifting door 361 is fitted inside the distance measuring box 3. The third gear 373 is connected to the first transmission wheel 362 via a shaft.

[0039] Specifically, during operation, the entire device may become contaminated with static electricity due to its substation environment. Insulating shells are installed on the supporting chassis 1, lifting platform 2, distance measuring box 3, and drive box 4 to reduce the risk of static electricity damage to personnel. Furthermore, during operation, the second motor 364 drives the third transmission wheel 365 to rotate, allowing the fan 367 to blow away the charge generated inside the ion fan chamber 36. The rotation of the third transmission wheel 365 also drives the second transmission wheel 363, the first transmission wheel 362, and the third gear 37. 3. The rotation of the first gear 371 and the second gear 372 drives the lifting door 361 to rise, so that the air blown by the fan 367 can carry the charge and blow towards the flow equalization plate 368. The flow equalization plate 368 has evenly distributed through holes inside, so that the air can be blown evenly into the distance measuring box 3 to eliminate static electricity. When the device is not working, the second motor 364 drives the third transmission wheel 365 to rotate. At this time, the fan 367 absorbs the heat inside the distance measuring box 3 and dissipates it through the ventilation net 366. At this time, the lifting door 361 slowly descends.
