Abstract
Description
Technical Field
[0001] This application relates to the field of high-voltage protection technology for locomotives, specifically to a door and window protection structure for a high-voltage chamber, a high-voltage protection door, and a high-voltage protection window. Background Technology
[0002] Electric locomotives have various high-voltage equipment in the machine room. There are multiple perforated doors and windows between the machine room and the corridor. The main function of these doors and windows is to draw cold outdoor air into the machine room under the action of exhaust fans to dissipate heat for various motors, auxiliary machines and other high-voltage equipment, so as to ensure the normal operation of the high-voltage equipment.
[0003] Meanwhile, during their corridor patrols, locomotive crew members and testing personnel can easily observe the status of equipment inside the machine room through pre-drilled holes in the doors and windows. Furthermore, the doors and windows, along with their metal mesh panels, prevent personnel from accidentally touching the high-voltage equipment inside the machine room, thus protecting their safety and preventing electric shock.
[0004] However, during operation or testing of high-voltage equipment in the machine room, a malfunction due to the high voltage can cause localized burns or sparks to fly, resulting in the splashing of iron filings or other components. The metal protective mesh on doors and windows cannot prevent these sparks, iron filings, or components from flying from the machine room into the corridor, thus posing a safety hazard. Utility Model Content
[0005] The purpose of this application is to provide a door and window protection structure for a high-pressure chamber, a high-pressure protective door, and a high-pressure protective window to improve the protection effect between the machine room and the corridor.
[0006] To achieve the above objectives, this application adopts the following technical solution:
[0007] In a first aspect, some embodiments of this application provide a door and window protection structure for a high-pressure chamber, including a positioning frame, a first protective plate, and a second protective plate. The positioning frame has an observation opening, and the first protective plate is disposed at the observation opening and connected to the positioning frame, and the first protective plate has a plurality of first vent holes. The second protective plate is disposed at the observation opening and connected to the positioning frame, and the second protective plate has a plurality of second vent holes. The second protective plate and the first protective plate are spaced apart, and the second vent holes are offset from the first vent holes in the vertical projection of the first protective plate.
[0008] In some embodiments, the door and window protection structure of the high-pressure chamber further includes a third protective plate, which is disposed at the observation port and connected to the positioning frame. The third protective plate has multiple third vent holes. Along the axial direction of the third vent holes, the third protective plate is spaced apart from the first and second protective plates. The first and / or second vent holes adjacent to the third protective plate are offset from the third vent holes in their vertical projections on the third protective plate.
[0009] In some implementations, the light transmittance of the first protective plate is 60%-80%, 80%-90%, 90%-95%, or above 95%.
[0010] In some implementations, the light transmittance of the second protective plate is 60%-80%, 80%-90%, 90%-95%, or above 95%.
[0011] In some implementations, the light transmittance of the third protective plate is 60%-80%, 80%-90%, 90%-95%, or above 95%.
[0012] In some embodiments, along the axial direction of the first vent hole, the third protective plate and the second protective plate are spaced apart and positioned on opposite sides of the first protective plate. The third vent hole is offset from the first vent hole in its vertical projection onto the first protective plate.
[0013] In some embodiments, the third vent hole overlaps with the second vent hole in the vertical projection of the second protective plate.
[0014] In some embodiments, a plurality of third vent holes are provided in a one-to-one correspondence with a plurality of second vent holes, and a third vent hole is coaxially arranged with a second vent hole.
[0015] In some embodiments, the diameter of the second vent is larger than that of the first vent.
[0016] In some embodiments, the diameter of the first vent is larger than that of the third vent.
[0017] In some embodiments, the first protective plate, the second protective plate, and the third protective plate are made of materials including glass, plexiglass, or acrylic sheets.
[0018] In some embodiments, the protective structure for the doors and windows of the high-pressure chamber further includes a metal mesh, which is disposed at the observation port and connected to the positioning frame. Along the axial direction of the first vent, a first protective plate and a second protective plate are disposed on the same side of the metal mesh.
[0019] In some embodiments, a metal mesh is spaced between the first protective plate and the second protective plate along the axial direction of the first vent hole.
[0020] Secondly, some embodiments of this application provide a high-pressure protective door, including a door body and a door / window protection structure for the high-pressure chamber mentioned in the first aspect. The door body has a first notch, and a positioning frame is installed at the first notch and connected to the door body.
[0021] Thirdly, some embodiments of this application provide a high-pressure protective window, including a window body and a door and window protective structure for the high-pressure chamber mentioned in the first aspect. The window body has a second notch, and a positioning frame is installed at the second notch and connected to the window body.
[0022] Because the observation port of the positioning frame is provided with a first protective plate and a second protective plate, the first protective plate is provided with a plurality of first vent holes and the second protective plate is provided with a plurality of second vent holes, so that an airflow channel is formed between the spaced first protective plate and the second protective plate by the first vent holes, the gap and the second vent holes, so that air can flow from the outside of the positioning frame 0 through the metal mesh and the airflow channel into the inside of the positioning frame to cool down the high-voltage equipment.
[0023] Furthermore, because the second vent is offset from the first vent in the vertical projection of the first protective plate, the first and second vents are prevented from being coaxially aligned, ensuring that the direction of the connecting channel between the first and second vents forms an angle with the axial direction. Thus, the first and second protective plates with offset vents can effectively shield and protect against sparks, metal filings, or parts ejected from the inner side. Attached Figure Description

[0045] The engine room of an electric locomotive is an area used to install various high-voltage equipment. To protect personnel, multiple doors and windows with mesh panels are installed between the engine room and the corridor. For example... Figure 1 As shown, the high-voltage room doors and windows currently in use are made of woven or welded wire mesh with a mesh diameter of approximately 3-4 cm. During operation or testing under high voltage conditions, the electric locomotive's pantograph introduces the 25KV voltage from the contact network into the locomotive through equipment. After processing by high-voltage equipment such as the main transformer and rectifier in the mechanical room, the high-voltage electricity is output to supply power to the corresponding equipment.
[0046] For example, in related technologies, taking the SS4 type (SS4G type / SS4B type) electric locomotive as an example, there are twenty high-voltage chamber perforated doors and windows between the machine room and the corridor of this electric locomotive. The main function of these doors and windows is to draw cold outdoor air into the machine room under the action of the exhaust fan, so as to dissipate heat for various motors and auxiliary machines to ensure normal operation.
[0047] Meanwhile, during their corridor patrols, locomotive crew members and testing personnel can easily observe the status of equipment inside the machine room through pre-drilled holes in the doors and windows. In this way, the doors and windows isolate the high-voltage equipment inside the machine room from personnel in the corridor, protecting personal safety and preventing close-range electric shock. In short, by centrally installing high-voltage equipment within the machine room and providing enclosed isolation through perforated doors and windows, the personal safety of crew members and locomotive testing personnel is protected.
[0048] However, when high-voltage equipment malfunctions due to the high voltage, the high-voltage current can discharge to components or cause localized burning, sparks, and flying metal filings or parts. Since the protective netting on doors and windows cannot prevent sparks, metal filings, or parts from flying from the machine room into the corridor, if personnel are passing through or near the machine room, the flying sparks, metal filings, or parts can cause cuts, punctures, or burns, leading to safety accidents. Therefore, this application provides a door and window protection structure for a high-voltage chamber, a high-voltage protective door, and a high-voltage protective window to solve the above problems. The following is a detailed explanation... Figures 2 to 7 This application describes in detail the door and window protection structure of the high-pressure chamber, the high-pressure protection door, and the high-pressure protection window in the embodiments of this application.
[0049] Firstly, such as Figure 2 and Figure 3 As shown, the door and window protection structure of the high-pressure chamber (hereinafter referred to as door and window protection structure 100) includes a positioning frame 10, a first protective plate 20, and a second protective plate 30. (Refer to...) Figure 4 The positioning frame 10 has an observation port 11. A first protective plate 20 is positioned at the observation port 11 and connected to the positioning frame 10. The first protective plate 20 has multiple first ventilation holes 21. A second protective plate 30 is positioned at the observation port 11 and connected to the positioning frame 10. The second protective plate 30 has multiple second ventilation holes 31. The second protective plate 30 is spaced apart from the first protective plate 20, and the second ventilation holes 31 are offset from the first ventilation holes 21 in the vertical projection of the first protective plate 20. Therefore, the positioning frame 10 facilitates the positioning and installation of the first protective plate 20 and the second protective plate 30, among other protective structures.
[0050] The positioning frame 10 can be part of the door or window structure. For example, if the positioning frame 10 is an integral structure with the door (or window), it has better stability. Alternatively, the positioning frame 10 and the door (or window) are independent components, and the positioning frame 10 is then installed at the notch in the door (or window), which facilitates the production and transportation of parts.
[0051] Alternatively, the positioning frame 10 can be directly set as the main structure of the door (or window), that is, the positioning frame 10 can be directly installed at the location where the door (or window) is installed, which is simple in structure.
[0052] Based on this, since the observation port 11 of the positioning frame 10 is provided with a first protective plate 20 and a second protective plate 30, the first protective plate 20 is provided with a plurality of first vent holes 21, and the second protective plate is provided with a plurality of second vent holes 31, so that an airflow channel is formed between the spaced first protective plate 20 and the second protective plate 30 by the first vent holes 21, the gap, and the second vent holes 31, so that air can flow from the outside of the positioning frame 10 through the metal mesh 50 and the airflow channel into the inside of the positioning frame 10 to cool down the high-voltage equipment.
[0053] Furthermore, because the second vent 31 is misaligned with the first vent 21 in the vertical projection of the first protective plate 20, the first and second vents 21 are prevented from being coaxially aligned, ensuring that the connecting channel between the first and second vents 21 forms an angle with the axial direction. Thus, the first and second protective plates 20 and 30, with their misaligned vents, provide effective shielding against sparks, metal filings, or parts ejected from the inner side. Moreover, the arrangement of the first and second vents 21 allows personnel on the outer side (e.g., in a corridor) to inspect and observe high-voltage equipment and other devices on the inner side from a certain perspective, resulting in a simple structure with good protective effect.
[0054] In the embodiments of this application, staggered distribution means that two structures are spaced apart or have no overlapping parts in their corresponding planes. Taking the first vent 21 and the second vent 31 as examples, the vertical projection of the second vent 31 on the first protective plate 20 is staggered from that of the first vent 21. That is, in the plane where the first protective plate 20 is located, the vertical projection of the second vent 31 is spaced apart from or adjacent to the first vent 21, meaning that there is no overlapping part between them.
[0055] Among them, there are multiple ways to shield and protect flying objects through the door and window protection structure 100.
[0056] Taking the installation of a first protective plate 20 and a second protective plate 30 at the positioning frame 10 as an example, the gap width between the first protective plate 20 and the second protective plate 30 can be adjusted along the axial direction of the first vent hole 21 so that the gap width is smaller than the radial dimension of the first vent hole 21 (and the second vent hole 31).
[0057] Taking the first protective plate 20 located on the inner side of the second protective plate 30 as an example, the first vent 21 is axially aligned with the body of the second protective plate 30. Even if a flying object passes through the first vent 21 at a large angle and is ejected outward, due to the small gap between the first protective plate 20 and the second protective plate 30, the object flying into the gap will collide with the body of the second protective plate 30, thus preventing the flying object from flying to the outside of the second protective plate 30. This provides good protection.
[0058] Or, such as Figure 5 As shown, the door and window protection structure 100 also includes a third protective plate 40, which is located at the observation port 11 and connected to the positioning frame 10. The third protective plate 40 has multiple third ventilation holes 41. Along the axial direction of the third ventilation holes 41, the third protective plate 40 is spaced apart from the first protective plate 20 and the second protective plate 30. The first ventilation hole 21 and / or the second ventilation hole 31 adjacent to the third protective plate 40 are offset from the third ventilation hole 41 in their vertical projection.
[0059] The third protective plate 40 is provided with multiple third vent holes 41, and the third protective plate 40 is spaced apart from the first protective plate 20 and the second protective plate 30 along the axial direction. This allows the gaps between the first protective plate 20, the second protective plate 30, and the third protective plate 40 to form a conductive airflow channel with the first vent holes 21, the second vent holes 31, and the third vent holes 41, for air exchange between the inner and outer sides of the positioning frame 10.
[0060] Furthermore, by setting the structure of the first vent 21 and the second vent 31 adjacent to the third protective plate 40, the vertical projection of the third protective plate 40 and the third vent 41 are staggered, so that the vent on the other plate can be blocked by one plate, thereby forming a double-layer shielding protection structure, which further improves the shielding and protection effect of the door and window protection structure against flying objects from both the inside and outside.
[0061] like Figure 5As shown, along the axial direction of the first vent 21, the third protective plate 40 and the second protective plate 30 are spaced apart on opposite sides of the first protective plate 20. Taking the third protective plate 40 located on the inner side of the second protective plate 30 along the axial direction as an example, the third vent 41 is misaligned with the first vent 21 in its vertical projection on the first protective plate 20, and the second vent 31 is also misaligned with the first vent 21 in its vertical projection on the first protective plate 20.
[0062] Thus, as the hot-temperature items splashing from the inner side fly towards the third protective plate 40, even if the splashed items can pass through the third vent 41, they will be blocked by the first protective plate 20 located outside the third vent 41. Even if some of the splashed items can continue to pass through the first vent 21 at a specific angle, they will be blocked by the second protective plate 30 located outside the first vent 21. In this way, through double-layer protection, the hot-temperature items splashing from the inner side can be effectively prevented from splashing to the outside through the door and window protection structure 100, thereby improving the protection effect and providing better safety.
[0063] In some embodiments, the light transmittance of the first protective plate 20, the second protective plate 30, and the third protective plate 40 is set to be greater than or equal to 60%. This allows personnel located outside the door and window protection structure 100 to directly observe the operation of high-voltage equipment and other items inside through the first protective plate 20, the second protective plate 30, and the third protective plate 40.
[0064] For example, the light transmittance of the first protective plate 20 can be set to 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99%. If the light transmittance of the first protective plate 20 is less than 60%, the three layers of plates are stacked to ensure that the inner and outer sides of the door and window protection structure 100 have low light transmittance, which is not conducive to visual observation between the inner and outer sides. For example, the light transmittance of the first protective plate 20 can be set to 60%-80%, 80%-90%, 90%-95%, or 95%.
[0065] The light transmittance of the second protective plate 30 can be set to 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99%. If the light transmittance of the second protective plate 30 is less than 60%, the three layers of plates are stacked to ensure that the inner and outer sides of the door and window protective structure 100 have low light transmittance, which is not conducive to visual observation between the inner and outer sides. For example, the light transmittance of the second protective plate 30 can be set to 60%-80%, 80%-90%, 90%-95%, or 95%.
[0066] Correspondingly, the light transmittance of the third protective panel 40 can be set to 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99%. If the light transmittance of the third protective panel 40 is less than 60%, the three layers of panels are stacked to ensure that the inner and outer sides of the door and window protection structure 100 have low light transmittance, which is not conducive to visual observation between the inner and outer sides. For example, the light transmittance of the third protective panel 40 can be set to 60%-80%, 80%-90%, 90%-95%, or 95%.
[0067] For example, the materials used to make the first protective plate 20, the second protective plate 30, and the third protective plate 40 include glass, plexiglass, or acrylic sheets. That is, by using the above materials to make the first protective plate 20, the second protective plate 30, and the third protective plate 40, they can achieve a light transmittance of 85% or more, or even exceeding 95%, so that personnel located outside the door / window protection structure 100 can have a better observation effect on high-voltage equipment and other items inside.
[0068] Taking the first protective plate 20, the second protective plate 30, and the third protective plate 40 as examples, which are made of acrylic sheets, the first protective plate 20, the second protective plate 30, and the third protective plate 40 have good toughness and high impact resistance. This prevents the sheets from breaking when hot, flying objects are blocked by the first protective plate 20, the second protective plate 30, or the third protective plate 40, thus effectively shielding and protecting flying objects.
[0069] In some embodiments, such as Figure 3 and Figure 5 As shown, the diameter of the second vent 31 is larger than that of the first vent 21.
[0070] For example, the aperture size (i.e., diameter) of the second vent 31 can be set to 9-11 cm. The aperture size of the first vent 21 can be set to 7-9 cm. For instance, the aperture size of the second vent 31 is 10 cm, and the aperture size of the first vent 21 is 8 cm.
[0071] Thus, by setting the second vent 31 on the outer side to have a larger aperture size and the first vent 21 on the inner side to have a smaller aperture size, the larger aperture size of the second vent 31 on the outer side reduces airflow resistance as external air flows inward through the second vent 31. This allows more air to flow quickly into the gap between the first protective plate 20 and the second protective plate 30, thereby increasing the amount of air flowing inward.
[0072] Furthermore, by setting the inner first vent 21 to have a smaller aperture size, the proportion of the opening area on the first protective plate 20 can be reduced, so that the first protective plate 20 has a higher shielding and protection efficiency against items splashing outward from the inside.
[0073] Correspondingly, in the case where a third protective plate 40 is also provided inside the first protective plate 20. For example... Figure 5 As shown, the diameter of the first vent 21 is larger than that of the third vent 41.
[0074] For example, the diameter of the third vent 41 can be set to 5-7 cm. For instance, the diameter of the third vent 41 is 6 cm, and the diameter of the first vent 21 is 8 cm.
[0075] Thus, from the outside in, the aperture sizes of the second vent 31, the first vent 21, and the third vent 41 decrease sequentially, that is, the aperture size of the outermost second vent 31.
[0076] By designing a larger diameter second vent 31 on the outer side and a smaller diameter first vent 21 on the inner side, external air flows inward through the second vent 31. The larger diameter of the outer vent 31 reduces airflow resistance, allowing more air to flow quickly into the gap between the first and second protective plates 20, thus increasing the inward airflow. Furthermore, by designing a smaller diameter third vent 41 on the inner side, the proportion of the opening area on the third protective plate 40 is reduced, resulting in higher shielding efficiency for objects splashing outward from the inner side.
[0077] Thus, from the inside out, the aperture sizes of the second vent 31, the first vent 21, and the third vent 41 at the second protective plate 30, the first protective plate 20, and the third protective plate 40 can decrease sequentially. This allows the larger aperture vents on the outer side to increase the airflow, while the smaller aperture vents on the inner side can improve the protective plate's efficiency in blocking and protecting against objects splashing outwards from the inside.
[0078] Therefore, in the process of arranging the second protective plate 30, the first protective plate 20, and the third protective plate 40 at axial intervals, the axial spacing between the second protective plate 30 and the first protective plate 20 can be less than or equal to 5-7 cm. The axial spacing between the first protective plate 20 and the third protective plate 40 can also be less than or equal to 5-7 cm.
[0079] For example, the axial spacing between the second protective plate 30, the first protective plate 20, and the third protective plate 40 is 6 cm, meaning the axial width of the gap is less than or equal to the diameter of the third vent 41. This allows air to flow rapidly inwards through the gap between the two protective plates while simultaneously creating a large angle of inclination between the vents of adjacent protective plates relative to the axis. This significantly reduces the probability of splashing objects passing through both vents sequentially, thereby improving the effectiveness of shielding against splashing objects.
[0080] In some embodiments, such as Figure 5 As shown, the third vent 41 is positioned such that its vertical projection on the second protective plate 30 overlaps with that of the second vent 31. That is, the vertical projections of the second vent 31 and the third vent 41 on the first protective plate 20 overlap, and the two overlapping vertical projections are staggered from the first vent 21. This improves the staggered distribution of vents between adjacent protective plates, thereby enhancing the shielding efficiency against splashed objects.
[0081] For example, multiple second vent holes 31 and multiple third vent holes 41 can be provided on the second protective plate 30 and the third protective plate 40, respectively, and one second vent hole 31 and one third vent hole 41 are coaxially arranged. That is, at least the second protective plate 30 and the third protective plate 40 are arranged parallel and spaced apart, so that one second vent hole 31 can be coaxially arranged with one third vent hole 41.
[0082] Thus, on both the inner and outer sides of the first protective plate 20, the line connecting the third vent 41 and the first vent 21 and the line connecting the second vent 31 and the first vent 21 are approximately "V" shaped structures.
[0083] During the process of a high-temperature object splashing under high pressure or high current and approaching the door and window protection structure 100, the above-mentioned structure can reduce or prevent the high-temperature object splashing at a certain angle from passing directly through the three ventilation holes, so that one or more protective plates can play a better protective role.
[0084] In some embodiments, such as Figure 3 and Figure 5 As shown, the door and window protection structure 100 also includes a metal mesh 50, which is located at the observation port 11 and is connected to the positioning frame 10.
[0085] Thus, by installing a metal mesh 50 at the observation port 11 of the positioning frame 10, the inner and outer sides of the positioning frame 10 (or the door and window protection structure 100) are protected and isolated by the metal mesh 50. Since the metal mesh 50 is a mesh structure formed by metal weaving, welding, or stamping, it will not affect or obstruct the ventilation and observation of the door and window protection structure. Furthermore, the metal mesh 50 can also provide electromagnetic shielding, preventing the electromagnetic field from the high-voltage equipment inside the positioning frame 10 from affecting the outside.
[0086] It should be noted that during the improvement of the isolation structure, including the metal mesh, the original metal mesh can be retained, and corresponding protective plate structures can be installed on one side of the metal mesh or on both the inner and outer sides to form a new door and window protection structure.
[0087] For example, such as Figure 3 and Figure 5 As shown, along the axial direction of the first vent 21, the first protective plate 20 and the second protective plate 30 are disposed on the same side of the metal mesh 50, so that the metal mesh 50 is part of the door and window protection structure 100.
[0088] For example, the first protective plate 20 and the second protective plate 30 can be located inside the metal mesh 50. Alternatively, the first protective plate 20, the second protective plate 30, and the third protective plate 40 can all be located inside the metal mesh 50. This avoids the first protective plate 20, the second protective plate 30, and the third protective plate 40 encroaching on the corridor space outside the metal mesh 50, thus providing personnel with ample space for inspection and movement.
[0089] Alternatively, the first protective plate 20 and the second protective plate 30 can be positioned outside the metal mesh 50. Or, the first protective plate 20, the second protective plate 30, and the third protective plate 40 can all be positioned outside the metal mesh 50. This allows the structurally strong metal mesh 50 to provide initial shielding against larger flying objects from the inside, thereby improving the overall stability of the door and window protection structure 100.
[0090] In addition, along the axial direction of the first vent hole 21, the metal mesh 50 can also be spaced between the first protective plate 20 and the second protective plate 30. Alternatively, the metal mesh 50 can be spaced between the first protective plate 20 and the third protective plate 40.
[0091] In this way, the metal mesh 50, spaced apart along the axial direction, will not obstruct the airflow between two adjacent protective plates. It also facilitates the flexible arrangement of the first protective plate 20, the second protective plate 30, and the third protective plate 40.
[0092] In some other embodiments, the door and window protection structure 100 may not require the installation of a metal mesh at the positioning frame 10. That is, the first protective plate 20, the second protective plate 30, and the third protective plate 40 can also provide good shielding against the view of hot objects splashing from the inside, thereby preventing people on the outside from being stabbed or burned.
[0093] Secondly, such as Figure 6 As shown, this application embodiment also provides a high-pressure protective door 200, which includes a door body 201 and the door and window protective structure 100 mentioned in the first aspect. The door body 201 is provided with a first notch 202, combined with... Figure 3 The positioning frame 10 is installed at the first notch 202 and connected to the door body 201.
[0094] Thus, when the door 201, which is installed by rotation or by sliding, is in the closed state, airflow can be achieved on both the inside and outside sides of the door 201 through the door and window protection structure 100 at the first notch 202. The door and window protection structure 100 also allows personnel to observe the high-voltage equipment inside the door 201 from the outside.
[0095] Since the high-pressure protective door 200 includes the door and window protection structure 100 in the first aspect, the high-pressure protective door 200 has all the beneficial effects of the aforementioned door and window protection structure 100, which will not be elaborated here.
[0096] Thirdly, such as Figure 7 As shown, this application embodiment also provides a high-pressure protective window 300, which includes a window body 301 and the door and window protective structure 100 mentioned in the first aspect. The window body 301 is provided with a second notch 302, combined with... Figure 3 The positioning frame 10 is installed at the second notch 302 and connected to the form 301.
[0097] Thus, when the window 301, whether rotated, pushed, or fixed, is in a closed state, the airflow channels on both the inside and outside of the window 301 can be realized through the door and window protection structure 100 at the second notch 302, and personnel can observe the high-voltage equipment inside the window 301 from the outside through the door and window protection structure 100.
[0098] Since the high-pressure protective window 300 includes the door and window protection structure 100 in the first aspect, the high-pressure protective window 300 has all the beneficial effects of the door and window protection structure 100 mentioned above, which will not be elaborated here.
