Description

Technical Field

[0001] This application relates to the field of electrical equipment for mining, and in particular to a high-voltage power distribution device. Background Technology

[0002] During the maintenance and repair of high-voltage power distribution equipment, ensuring the safety of operators is the top priority. Traditional combination locks or simple electrical interlocking devices may malfunction during maintenance if, after the maintenance personnel have disconnected the power, someone else accidentally re-energizes the equipment, leading to a dangerous situation.

[0003] Regarding the aforementioned technologies, the applicant believes that there is a lack of functionality to restrict the device to a function that can only be restored by maintenance personnel after a power outage, which poses certain safety hazards. Summary of the Invention

[0004] To improve the safety performance of high-voltage power distribution equipment, this application provides a high-voltage power distribution device.

[0005] This application provides a high-voltage power distribution device, which adopts the following technical solution: A high-voltage power distribution device, characterized in that it includes a metal housing and an operating panel and a protection mechanism mounted on the metal housing. The operation panel includes a camera for collecting information and a display screen for displaying information. The operation panel has a face recognition system and an operation gesture recognition system for recognizing the operator's identity and operation commands. The protective mechanism is used to shield and protect the operation panel when not in operation.

[0006] By adopting the above technical solution, when a power outage is required for maintenance, the operator opens the protective mechanism, exposing the control panel. A camera captures the operator's facial and gesture information. The facial recognition system identifies the operator's face to unlock the panel and then performs a power-off action based on the operator's gestures. After maintenance is completed, only the designated operator can restore power. This process effectively prevents the risk of other personnel accidentally restoring power after the designated operator has restored it.

[0007] Preferably, the protective mechanism includes a central tube disposed on a metal housing, a rotating shaft rotatably connected to the central tube, and a protective cover mounted on the rotating shaft. When the protective cover is not subjected to any other force outside the protective mechanism, the protective cover covers the panel body.

[0008] By adopting the above technical solution, the control panel can be enclosed by a protective cover when not in use. Given the harsh environment inside mines, this protective mechanism effectively protects the control panel and extends the equipment's lifespan.

[0009] Preferably, the central tube is horizontal and the rotating shaft passes through the central tube. The diameter of the rotating shaft is equal to the inner diameter of the central tube. Both ends of the rotating shaft are formed with mounting shafts with a diameter smaller than the rotating shaft. The mounting shafts are semi-cylindrical. The protective cover includes a cover plate and lugs connected to the upper two ends of the cover plate. Each lug is formed with a semi-circular through hole that is adapted to the size of the mounting shaft. The mounting shafts at both ends of the rotating shaft fix the central tube and the protective cover through the through holes of the snap-fit ​​parts on both sides of the protective cover.

[0010] By adopting the above technical solution, the rotating shaft and the central shaft tube can be matched and rotate relative to each other, and the two ends of the rotating shaft are fixedly connected to the support ears of the protective cover through the mounting shaft, so that the rotating shaft rotates together with the protective cover during the rotation process, and the protective cover structure will not be worn during the rotation process.

[0011] Preferably, each end of the rotating shaft is fitted with a torsion spring that applies a force to the protective cover to rotate in the direction of the operation panel.

[0012] By adopting the above technical solution, the torsion spring applies force so that the protective cover covers the control panel when no external force is applied, thus effectively protecting the control panel.

[0013] Preferably, a first connecting hole is formed on the side of the central tube near both the left and right ends, and a groove is formed on the side of the rotating shaft that extends through both ends of the rotating shaft along the length of the rotating shaft. A second connecting hole is formed on the bottom surface of the groove near both ends of the rotating shaft. One end of the torsion spring sleeved on the rotating shaft passes through the groove into the central tube and exits from the first connecting hole of the central tube, while the other end of the torsion spring passes through the second connecting hole.

[0014] By adopting the above technical solution, one end of the torsion spring passes through a groove and then protrudes from the first connecting hole, thus fixing one end of the torsion spring to the central shaft tube. The other end of the torsion spring is fixedly connected to the rotating shaft by passing through the second connecting hole. After both ends of the torsion spring are fixed, since the central shaft tube is fixed to the metal housing, the torsion spring applies a force to the rotating shaft to rotate it, causing the protective cover to cover the operation panel.

[0015] Preferably, a rubber strip is adhered around the perimeter of the protective cover facing the control panel.

[0016] By adopting the above technical solution, the rubber strip around the circumference of the protective cover forms a sealing surface between the protective cover and the metal shell, protecting the control panel and providing better protection for the control panel.

[0017] Preferably, the protective cover is made of insulating material.

[0018] By adopting the above technical solution, the insulated protective cover allows operators to touch only the insulated protective cover during operation, without having to directly touch the potentially energized parts of the high-voltage power distribution device before power is cut off, making the maintenance operation safer.

[0019] Preferably, the central tube is horizontal and the rotating shaft passes through the central tube. The diameter of the rotating shaft is equal to the inner diameter of the central tube, and the length of the rotating shaft is equal to the length of the central tube. The two ends of the rotating shaft are formed with mounting shafts smaller than the rotating shaft. The mounting shafts are non-cylindrical. The protective cover includes a cover plate and first side plates extending from the left and right sides of the cover plate and second side plates extending from the lower side plate of the cover plate. The first side plates and the second side plates are integrally formed. The upper ends of the two first side plates are each formed with a rhomboid through hole at a relative position. The shape and size of the through hole are adapted to the mounting shaft.

[0020] By adopting the above technical solution, the protective cover is installed together with the mounting shaft through the through hole, and the protective cover can rotate along the central tube to complete the opening and closing of the protective cover.

[0021] Preferably, multiple mounting grooves are evenly distributed on the inner wall of the first side plate, and an integrally formed sealing rubber gasket is fitted on the first side plate and the second side plate. The sealing rubber gasket covers the inner side of the first side plate and the second side plate to the side of the first side plate and the second side plate facing away from the cover plate and the outer side of the first side plate and the second side plate. A mounting post is formed in the position of the rubber sealing gasket opposite the mounting groove. The diameter of the mounting post is interference-fitted with the mounting groove and the end is chamfered.

[0022] By adopting the above technical solution, a sealing rubber gasket is installed using an mounting groove. When the protective cover is closed, a sealing surface is formed between the sealing rubber gasket and the metal shell, achieving a more effective dustproof effect. Simultaneously, the rubber gasket acts as a buffer when the protective cover is closed.

[0023] Preferably, the distance between the two first side plates is greater than the length of the shaft, and the portion of the sealing rubber pad located between the shaft, the central tube and the first side plate is compressed to form a seal. A small strong magnet is embedded in the mounting groove near the center of each first side plate.

[0024] By adopting the above technical solution, when power-off maintenance is required, the operator flips the protective cover upwards to expose the control panel. When the protective cover is opened to contact the metal casing, the magnetic force between the small, strong magnet and the metal casing locks the cover in the open position. At this point, the operator's hands are freed. The camera on the control panel captures and recognizes the operator's face to unlock the device and performs a power-off action based on the operator's gestures. After maintenance is completed, the operator restores power and closes the protective cover. When the cover is closed, in addition to its own weight, the magnetic force between the small, strong magnet and the metal casing ensures the cover adheres tightly to the metal casing, providing better dust protection.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When power-off maintenance is required, the operator opens the protective mechanism, exposing the control panel. The facial recognition system identifies the operator's face to unlock the panel and then performs a power-off action based on the operator's gestures. After maintenance is completed, only the designated operator can restore power. This process effectively prevents the risk of other personnel accidentally restoring power after the designated operator has restored it.

[0026] 2. When not in use, the control panel can be covered by a protective cover. Due to the harsh environment inside mines, the protective mechanism can effectively protect the control panel and extend the service life of the equipment.

[0027] 3. One end of the torsion spring passes through a groove and then through the first connecting hole, thus fixing one end of the torsion spring to the central shaft tube. The other end of the torsion spring is fixed to the rotating shaft by passing through the second connecting hole. After both ends of the torsion spring are fixed, since the central shaft tube is fixed to the metal housing, the torsion spring applies a force to the rotating shaft to rotate it, causing the protective cover to cover the operation panel.

[0028] 4. The insulated protective cover allows operators to touch only the cover during operation, rather than directly touching potentially energized parts of the high-voltage power distribution equipment before power is cut off, making maintenance operations safer.

[0029] 5. When power-off maintenance is required, the operator flips the protective cover upwards to expose the control panel. When the cover is fully open and comes into contact with the metal casing, the magnetic force between the small, strong magnet and the metal casing locks the cover in the open position. This frees the operator's hands. The camera on the control panel captures and recognizes the operator's face to unlock the panel and performs a power-off action based on the operator's gestures. After maintenance is completed, the operator restores power and closes the protective cover. When the cover is closed, in addition to its own weight, the magnetic force between the small, strong magnet and the metal casing ensures the cover adheres tightly to the metal casing, providing better dust protection.

[0032] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0033] This application discloses a high-voltage power distribution device. The terms "up," "down," "left," and "right" used in the embodiments are schematic representations of relative directions and are not limitations on the positional relationship.

[0034] Example 1:

[0035] like Figure 1 As shown, the high-voltage power distribution device includes a metal casing 1 and an operation panel 2 and a protection mechanism 3 mounted on the metal casing 1. The operation panel 2 includes a panel body and a display screen and a camera mounted on the panel body. The operation panel 2 has a facial recognition system and an operation gesture recognition system. The facial recognition system identifies the operator's identity, and the operation gesture recognition system identifies the operation commands.

[0036] like Figure 2 As shown, the protective mechanism 3 includes a central tube 4 welded and fixed to the metal housing 1 above the operation panel 2, a rotating shaft 5 connected to the central tube 4, and a protective cover 6 mounted on the rotating shaft 5. A first connecting hole 7 is formed on the side of the central tube 4 near both ends. The central tube 4 is horizontal, and the rotating shaft 5 passes through it. The diameter of the rotating shaft 5 is equal to the inner diameter of the central tube 4. Mounting shafts 8 with diameters smaller than the rotating shaft 5 are formed at both ends of the rotating shaft 5; the mounting shafts 8 are semi-cylindrical. Grooves 9 are formed on the side of the rotating shaft 5, extending through both ends along its length. Second connecting holes 10 are formed on the bottom surface of the grooves 9 near both ends of the rotating shaft 5. A torsion spring 11 is fitted at each end of the rotating shaft 5 where it exits the central tube 4. One end of the torsion spring 11 passes through the groove 9 into the central tube 4 and exits through the first connecting hole 7 of the central tube 4; the other end of the torsion spring 11 passes through the second connecting hole 10. The torsion spring 11 applies a force to the protective cover 6, so that the protective cover 6 covers the operation panel 2 when it is not subjected to other external forces.

[0037] like Figure 2 As shown, the protective cover 6 is made of insulating material, preferably a polymer in this embodiment. The protective cover 6 includes a cover plate 12 and lugs 13 connected to both ends of the upper side of the cover plate 12. Each lug 13 has a semi-circular through hole 14 that is adapted to the size of the mounting shaft 8. The mounting shafts 8 at both ends of the rotating shaft 5 are fixedly connected to the central shaft tube 4 and the protective cover 6 through the through holes 14 of the snap-fit ​​parts on both sides of the protective cover 6. A rubber strip 15 is glued around the circumference of the protective cover 6 facing the operation panel 2. When the protective cover 6 is pressed against the metal housing 1 by the torsion spring 11, the operation panel 2 is located within the circle of the rubber strip 15.

[0038] Specific usage process: When a power outage is required for maintenance, the operator flips up the protective cover 6 to expose the control panel 2. A camera on the control panel 2 captures and recognizes the operator's face to unlock the device, and then the power is cut off based on the operator's gestures. After maintenance, only the designated operator can restore power. This process effectively prevents the risk of other personnel accidentally re-energizing the device after the operator has successfully de-energized it. Furthermore, during operation, the operator only needs to touch the insulated protective cover 6, avoiding direct contact with potentially energized parts of the high-voltage power distribution equipment before the power is cut off, making the process safer.

[0039] Example 2:

[0040] like Figure 3As shown, the only difference between this embodiment and Embodiment 1 is the structure of the protection mechanism 3. The protection mechanism 3 in this embodiment includes a central shaft tube 4 welded and fixed to the metal housing 1 above the operation panel 2, a rotating shaft 5 connected to the central shaft tube 4, and a protective cover 6 installed on the rotating shaft 5.

[0041] like Figure 3 As shown, the central tube 4 is horizontal and the rotating shaft 5 is inserted inside the central tube 4. The diameter of the rotating shaft 5 is equal to the inner diameter of the central tube 4, and the length of the rotating shaft 5 is equal to the length of the central tube 4. At both ends of the rotating shaft 5, there are mounting shafts 8 with a size smaller than the rotating shaft 5. The mounting shafts 8 are prismatic.

[0042] like Figure 3 As shown, the protective cover 6 is made of acrylic and includes a cover plate 12 and first side plates 16 extending from the left and right sides of the cover plate 12, and a second side plate 17 extending from the lower side plate of the cover plate 12. The first side plates 16 and the second side plates 17 are integrally formed. The distance between the two first side plates 16 is slightly greater than the length of the rotating shaft 5. The upper ends of the two first side plates 16 are each formed with a diamond-shaped through hole 14 at a relative position. The shape and size of the through hole 14 are adapted to the mounting shaft 8.

[0043] like Figure 3 and Figure 4 As shown, at least three circular mounting grooves 18 are evenly distributed on the inner walls of the two first side plates 16. A small, circular, strong magnet 19 is embedded in the mounting groove 18 near the center of each first side plate 16. The size of the small, strong magnet 19 matches the size of the mounting groove 18. An integrally formed sealing rubber gasket 20 is fitted onto the first side plate 16 and the second side plate 17. The sealing rubber gasket 20 covers the inner side of the first side plate 16 and the second side plate 17, extending to the side of the first side plate 16 and the second side plate 17 facing away from the cover plate 12, and to the outer side of the first side plate 16 and the second side plate 17. Mounting posts 21 are formed on the rubber sealing gaskets opposite the mounting grooves 18. The diameter of the mounting posts 21 is interference-fitted with the mounting grooves 18, and the ends are chamfered. The portion of the sealing rubber gasket 20 located between the rotating shaft 5, the central shaft tube 4, and the first side plate 16 is compressed to form a seal, and the sealing rubber gasket 20 also acts as a damping element.

[0044] Specific usage process: When a power outage is required for maintenance, the operator flips the protective cover 6 upwards to expose the control panel 2. When the protective cover 6 is opened to contact the metal housing 1, the protective cover 6 is locked in the open state by the magnetic force between the small strong magnet 19 and the metal housing 1. At this time, the operator's hands can be freed. The camera on the control panel 2 captures and recognizes the operator's face to unlock the device and performs a power outage action based on the operator's gestures.

[0045] After maintenance is completed, the operator will power on the device and then close the protective cover 6. When the protective cover 6 is closed, in addition to its own weight, the magnetic force between the small strong magnet 19 and the metal shell 1 will also cause the protective cover 6 to fit tightly against the metal shell 1, thus better protecting it from dust.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
