Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and in particular to a distribution box with a maintenance lighting structure. Background Art

[0002] The distribution box is a commonly used electrical auxiliary equipment in industry. During the inspection or repair process of the distribution box, since the distribution box cannot be powered by itself, the inspection or repair personnel need to carry additional lighting equipment to provide lighting so that they can clearly see the status of the electrical accessories inside the distribution box for maintenance or replacement of the electrical accessories. The inspection or repair personnel carry lighting equipment by themselves, which not only increases the overall weight of the maintenance tools, but also makes it inconvenient to use conventional lighting equipment to adjust the light source irradiation position of the components inside the distribution box, which is not convenient when inspecting or repairing the distribution box. Summary of the invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a distribution box with a maintenance lighting structure to solve the problem that maintenance or emergency repair personnel carrying lighting equipment by themselves not only increases the overall weight of the maintenance tools, but also it is inconvenient to use conventional lighting equipment to adjust the light source irradiation position of the internal components of the distribution box, resulting in inconvenience during the maintenance or emergency repair of the distribution box.

[0004] According to an embodiment of the present application, a distribution box with a maintenance lighting structure includes: a distribution box main body, a lighting adjustment part and a lighting main body part.

[0005] The main part of the distribution box includes a box shell with an open top structure and a box door, and the box door is installed on the front of the box shell; the lighting adjustment part includes an outer cover shell, a lower cover plate, a top plate, a back cover plate, a transmission belt and a handle, the top plate is fixed to the top of the outer cover shell, the back cover plate is arranged on the back of the outer cover shell, the outer cover shell is installed on the top of the box shell, the lower cover plate is arranged on the bottom of the outer cover shell on the front side of the box shell, the transmission belt passes through and circulates around the outside and inside of the outer cover shell, and the handle is located on the outside of the outer cover shell and fixedly connected to the transmission belt; the lighting main part includes a battery, a push button switch and a lighting part, the battery is installed inside the box shell, the push button switch is arranged on the front side of the box shell, and the lighting part is installed on the side of the transmission belt located inside the outer cover shell.

[0006] When the box door is closed on the front of the box shell, the box door can press the button switch on the front of the box shell. At this time, the circuit connection between the battery, the button switch, and the lighting unit is a closed circuit setting. When the internal circuit of the distribution box is powered off, the maintenance personnel need to inspect or repair the electrical accessories inside the distribution box. The operator first needs to open the box door on the front of the box shell. When the box door is opened, the box door removes the pressure on the button switch. At this time, a closed circuit is formed between the button switch, the battery, and the lighting unit. The battery supplies power to the lighting unit for lighting inside the distribution cabinet. This design can ensure that when the power distribution cabinet is powered off, the maintenance personnel do not need to carry additional lighting equipment. The lighting provided inside the distribution box will automatically light up the inside of the distribution box when the box door is opened, which is convenient for the operator to inspect and maintain the electrical components inside the distribution box. When the lighting unit provides lighting for the inside of the box shell, since the multiple electrical components inside the box shell are in different positions inside the box shell, the lighting unit can also be adjusted appropriately according to needs. The specific adjustment method is as follows: the maintenance personnel pinch the handle outside the transmission belt with one hand outside and push the handle to move along the outer ring of the outer cover shell. The moving handle will drive the transmission belt to move synchronously along the outside and inside of the outer shell, and finally drive the lighting part on the transmission belt inside the outer shell to move and adjust the position. Since the lighting part moves along the transmission belt in the area of ​​the inner wall of the outer shell, the projection position of the lighting light source of the lighting part can be adjusted appropriately according to the different positions of the electrical components inside the box shell, ensuring that the electrical components in the repaired area have better lighting conditions, and further facilitating the maintenance personnel to repair or maintain the electrical components in the corresponding area inside the box shell.

[0007] In some embodiments of the present application, the lighting unit includes a support and a lighting lamp, the support is connected to a transmission belt inside the outer cover, and the lighting lamp is installed on a side of the support.

[0008] In some embodiments of the present application, an upper guide groove and a lower guide groove are respectively provided at the top and bottom of the inner side of the outer cover shell, an upper roller cooperating with the upper guide groove is provided at the top of the support, and a lower roller cooperating with the lower guide groove is provided at the bottom of the support.

[0009] In some embodiments of the present application, the lighting unit further includes a reflector, which is disposed on the top of the lighting lamp and connected to the support.

[0010] In some embodiments of the present application, a mounting opening is provided on the support, and the transmission belt passes through the mounting opening and is fixedly connected to the support.

[0011] In some embodiments of the present application, avoidance grooves are provided at the top and bottom of the support.

[0012] In some embodiments of the present application, the lighting adjustment part further includes an inner limit block, and the inner limit block is arranged on the outer side of the outer cover shell to limit the transmission belt.

[0013] In some embodiments of the present application, the lighting adjustment part further includes an outer limit block, and the outer limit block is arranged on the inner side of the outer cover to limit the transmission belt.

[0014] In some embodiments of the present application, a guide wheel is rotatably provided at one end of the outer cover shell close to the back sealing plate, and the transmission belt passes through the outer side of the guide wheel.

[0015] In some embodiments of the present application, a groove for installing a guide wheel and passing a transmission belt is provided at the end of the outer cover shell close to the back sealing plate.

[0016] The distribution box with maintenance lighting structure also includes a reflection enhancement part, which includes a lower reflector and an upper reflective enhancement component. The lower reflector is fixed to the upper surface of the lower sealing plate, and the upper reflective enhancement component is located above the lower reflector. The upper reflective enhancement component includes a back plate, a connecting plate and an upper reflector. Multiple back plates are tilted and fixed at the bottom of the top plate, and the connecting plate connects two adjacent back plates. A card slot is provided below the back plate, and the upper reflector is fixedly embedded in the card slot.

[0017] When the lighting unit is adjusted and moved to the front end of the outer shell between the lower sealing plate and the top plate, the downward light of the lighting unit will be projected onto the lower reflector on the upper surface of the lower sealing plate. The lower reflector reflects the light source to the upper reflector tilted above, and multiple tilted upper reflectors reflect the light source to the lower reflector, until the upper reflector near the top area of ​​the box shell finally reflects the light source to the electrical components on the front inside the box shell. Similarly, the upward light emitted by the lighting unit will be directly projected onto the upper reflector, and the upper reflector will reflect the light source to the lower reflector. After reflection by multiple groups of upper and lower reflectors, the upper reflector near the top area of ​​the box shell finally reflects the light source to the electrical components on the front inside the box shell. That is, when the lighting unit is in the inner area of ​​the outer shell above the lower sealing plate, through the cooperation of the reflection enhancement part, the light source projected by the lighting unit can also be projected more on the electrical components on the front inside the box shell. During inspection and maintenance, operators can see the electrical components in the front of the box shell more clearly, making it easier for operators to inspect and maintain the internal electrical components.

[0018] The distribution box with an inspection lighting structure also includes a reflective adjustment part, which includes a backrest plate, a reflective plate, a shaft rod, a damping bearing and a knob. The backrest plate is located on one side of the upper reflective enhancement component, and the reflective plate is fixedly arranged below the backrest plate. The shaft rod is fixedly connected to the top of the backrest plate. Two groups of damping bearings are respectively installed on both sides of the outer cover shell, and both ends of the shaft rod are respectively rotated to pass through the side walls of the outer cover shell and connected to the damping bearings. The knob is installed at one end of the shaft rod.

[0019] When the lighting unit is located inside the outer cover above the lower sealing plate. In addition to the upper reflector that can directly project most of the light onto the electrical components on the front of the interior of the box shell, part of the light projected from the lower reflector to the top plate will be converted to be projected onto the reflective plate at the bottom of the top plate. The reflective plate then projects the light onto the electrical components on the front of the box shell. By turning the knob at the end of the shaft rod, the rotating knob drives the shaft rod to rotate, that is, the shaft rod drives the back plate and the reflective plate at the bottom to rotate, that is, the light source reflection angle of the reflective plate can be slightly adjusted, so that the light reflected from the lower reflector to the reflective plate is adjusted to be reflected at the angle to the electrical components in the designated area on the front of the interior of the box shell. The area caused by the light reflection is more accurate and bright, which can further improve the illumination brightness, and facilitate the operator to inspect and maintain the electrical components on the front of the interior of the box shell.

[0020] The beneficial effect of the present application is that the present application obtains a distribution box with a maintenance lighting structure through the above design. This design can ensure that when the power distribution cabinet is powered off, the maintenance personnel do not need to carry additional lighting equipment. The lighting provided inside the distribution box will automatically light up the inside of the distribution box when the box door is opened, which is convenient for the operators to inspect and maintain the electrical components inside the distribution box. When the lighting unit provides lighting for the inside of the box shell, since the multiple electrical components inside the box shell are in different positions inside the box shell, the lighting unit can also be appropriately adjusted according to the needs. The projection position of the lighting light source of the lighting unit can be adjusted appropriately to ensure that the electrical components in the repaired area have better lighting conditions, which further facilitates the maintenance personnel to repair or maintain the electrical components in the corresponding area inside the box shell.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0035] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0037] A distribution box with a maintenance lighting structure according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0038] See also Figure 1-Figure 9 According to an embodiment of the present application, a distribution box with a maintenance lighting structure includes: a distribution box main body part 10, a lighting adjustment part 20 and a lighting main body part 30.

[0039] Among them, the top of the distribution box main body 10 can provide lighting when the distribution box is powered off through the arrangement of the lighting adjustment part 20 and the lighting main body part 30, so that operators can carry out inspection and emergency repairs, making it convenient for operators to complete the inspection or emergency repairs of the distribution box.

[0040] See also Figure 1-Figure 5The main body 10 of the distribution box includes a box shell 110 with an open top structure and a box door 120. The box door 120 is installed on the front of the box shell 110. The lighting adjustment part 20 includes an outer cover shell 210, a lower sealing plate 220, a top plate 230, a back sealing plate 240, a transmission belt 250 and a handle 260. The top plate 230 is fixed to the top of the outer cover shell 210 by welding, and the back sealing plate 240 is set on the back of the outer cover shell 210 by welding. The outer cover shell 210 is installed on the top of the box shell 110, and the lower sealing plate 220 is set at the bottom of the outer cover shell 210 on the front side of the box shell 110. The transmission belt 250 runs through the outer and inner sides of the outer cover shell 210, and the handle 260 is located on the outer side of the outer cover shell 210 and is fixedly connected to the transmission belt 250. The main lighting part 30 includes a battery 310, a button switch 320 and a lighting unit 330. The battery 310 is installed inside the housing 110 , the button switch 320 is arranged on the front side inside the housing 110 , and the lighting unit 330 is installed on the side of the transmission belt 250 located inside the outer cover 210 .

[0041] The working principle of the distribution box with maintenance lighting structure is as follows: when the box door 120 is closed on the front of the box shell 110, the box door 120 can press the button switch 320 on the front of the box shell 110, and the circuit connection between the battery 310, the button switch 320, and the lighting unit 330 is a closed circuit setting. When the internal circuit of the distribution box is powered off, the maintenance personnel need to inspect or repair the electrical accessories inside the distribution box. The operator first needs to open the box door 120 on the front of the box shell 110. When the box door 120 is opened, the box door 120 removes the pressure on the button switch 320. At this time, a closed circuit is formed between the button switch 320, the battery 310, and the lighting unit 330, and the battery 310 supplies power to the lighting unit 330 for lighting inside the distribution cabinet. This design ensures that when the power distribution cabinet is powered off, maintenance personnel do not need to carry additional lighting equipment. The lighting provided inside the distribution box will automatically light up the inside of the distribution box when the box door 120 is opened, making it convenient for operators to inspect and maintain the electrical components inside the distribution box.

[0042] When the lighting unit 330 provides lighting for the inside of the box shell 110, since the multiple electrical components inside the box shell 110 are located at different positions inside the box shell 110, the lighting unit 330 can also be appropriately adjusted according to the needs. The specific adjustment method is as follows: the maintenance personnel pinch the handle 260 outside the transmission belt 250 with one hand outside, and push the handle 260 to move along the outer ring of the peripheral cover shell 210. The moving handle 260 will drive the transmission belt 250 to move synchronously along the outside and inside of the peripheral cover shell 210, and finally drive the lighting unit 330 on the transmission belt 250 inside the peripheral cover shell 210 to move and adjust the position. Since the lighting unit 330 moves along the transmission belt 250 in the area of ​​the inner side wall of the peripheral cover shell 210, according to the electrical components inside the box shell 110 are in different positions, the projection position of the lighting light source of the lighting unit 330 can be adjusted appropriately, ensuring that the electrical components in the repaired area have better lighting conditions, and further facilitating the maintenance personnel to repair or maintain the electrical components in the corresponding area inside the box shell 110.

[0043] In the above specific implementation, please refer to Figure 6 and Figure 7 The lighting unit 330 includes a support 331 and a lighting lamp 332. The support 331 is connected to the transmission belt 250 inside the outer shell 210 by bolts. The lighting lamp 332 is installed on the side of the support 331. The movable handle 260 can drive the transmission belt 250 around the outer shell 210 to move. The moving transmission belt 250 will synchronously drive the support 331 to move, that is, drive the lighting lamp 332 on one side of the support 331 to move and adjust the lighting position. The top and bottom of the inner side of the outer shell 210 are respectively provided with an upper guide groove 211 and a lower guide groove 212. The top of the support 331 is provided with an upper roller 333 that cooperates with the upper guide groove 211, and the bottom of the support 331 is provided with a lower roller 334 that cooperates with the lower guide groove 212. The upper roller 333 rolls inside the upper guide groove 211, and the lower roller 334 rolls inside the lower guide groove 212. This cooperation is to improve the stability of the support 331 when moving.

[0044] Furthermore, the lighting unit 330 further includes a reflector 335, which is arranged on the top of the lighting lamp 332 and fixedly connected to the support 331 by bolts. The reflector 335 can reflect the light source emitted by the lighting lamp 332 that diffuses upward downward, and can reflect more light brightness to the electrical components inside the box shell 110 below, thereby improving the lighting effect of the lighting lamp 332.

[0045] For further information, see Figure 5 , Figure 6 and Figure 7The support 331 is provided with a mounting opening 336, and the transmission belt 250 passes through the mounting opening 336 and is fixedly connected to the support 331 by bolts. The support 331 is provided with avoidance grooves 337 at the top and bottom, and the avoidance grooves 337 are provided to avoid the inner limit block 270 inside the outer cover 210. The lighting adjustment part 20 also includes an inner limit block 270. The inner limit block 270 is arranged on the outer side of the outer cover 210 to limit the transmission belt 250, and the inner limit block 270 is used to limit the part of the transmission belt 250 inside the outer cover 210. The lighting adjustment part 20 also includes an outer limit block 280, and the outer limit block 280 is arranged on the inner side of the outer cover 210 to limit the transmission belt 250, and the outer limit block 280 is used to limit the part of the transmission belt 250 outside the outer cover 210.

[0046] Specifically, a guide wheel 290 is rotatably provided at one end of the outer casing 210 close to the back sealing plate 240, and the transmission belt 250 passes through the outer side of the guide wheel 290. A notch for installing the guide wheel 290 and passing the transmission belt 250 is provided at the end of the outer casing 210 close to the back sealing plate 240. The guide wheel 290 is provided so that the transmission belt 250 can move smoothly through the guide wheel 290, thereby reducing the friction force when the transmission belt 250 moves.

[0047] When the light source emitted by the lighting part 330 in the above-mentioned distribution box with maintenance lighting structure is on both sides of the outer cover shell 210, it can well illuminate the electrical accessories on both sides of the interior of the box shell 110 for maintenance. However, when the lighting part 330 moves to the arc position area at the front end of the outer cover shell 210, the lower cover plate 220 will block part of the light source, and the electrical components on the front side of the box shell 110 cannot be illuminated by more light, which results in the light source on the front side of the box shell 110 not being strong enough.

[0048] See also Figure 4 , Figure 8 and Fig. 9 The distribution box with the maintenance lighting structure also includes a reflection enhancement part 40, which includes a lower reflector 410 and an upper reflector enhancement component 420. The lower reflector 410 is fixed to the upper surface of the lower sealing plate 220 by gluing. The upper reflector enhancement component 420 is located above the lower reflector 410, and the upper reflector enhancement component 420 includes a back plate 421, a connecting plate 422 and an upper reflector 423. A plurality of back plates 421 are tilted and fixed to the bottom of the top plate 230, and the connecting plate 422 connects two adjacent back plates 421. A card slot is provided below the back plate 421, and the upper reflector 423 is fixed and embedded in the card slot by gluing.

[0049] When the lighting unit 330 is adjusted and moved to the front end of the outer casing 210 between the lower sealing plate 220 and the top plate 230, the downward light of the lighting unit 330 will be projected onto the lower reflector 410 on the upper surface of the lower sealing plate 220. The lower reflector 410 reflects the light source to the upper reflector 423 tilted above, and the multiple tilted upper reflectors 423 reflect the light source to the lower reflector 410, until the upper reflector 423 near the top area of ​​the box shell 110 finally reflects the light source to the electrical components on the front inside the box shell 110. Similarly, the upward light emitted by the lighting unit 330 will be directly projected onto the upper reflector 423, and the upper reflector 423 will reflect the light source to the lower reflector 410, and after being reflected by multiple groups of upper reflectors 423 and lower reflectors 410, the upper reflector 423 near the top area of ​​the box shell 110 finally reflects the light source to the electrical components on the front inside the box shell 110. That is, when the lighting unit 330 is in the inner area of ​​the outer cover shell 210 above the lower sealing plate 220, the light source projected by the lighting unit 330 can be projected more on the electrical components on the front inside the box shell 110 through the cooperation of the reflective enhancement part 40. The operator can see the electrical components on the front inside the box shell 110 more clearly during inspection and maintenance, which is convenient for the operator to inspect and maintain the internal electrical components.

[0050] Part of the lower reflector 410 near the box shell 110 in the above-mentioned distribution box with maintenance lighting structure will also reflect part of the light source to the bottom surface of the top plate 230 above the box shell 110, resulting in a certain loss of projected light.

[0051] See also Figure 3 , Figure 4 and Figure 8 The distribution box with maintenance lighting structure also includes a reflective adjustment part 50, which includes a back plate 510, a reflective plate 520, a shaft 530, a damping bearing 540 and a knob 550. The back plate 510 is located on one side of the upper reflective enhancement assembly 420, the reflective plate 520 is fixedly arranged below the back plate 510, the shaft 530 is fixedly connected to the top of the back plate 510, two groups of damping bearings 540 are respectively installed on both sides of the outer cover 210, and the two ends of the shaft 530 are respectively rotated to penetrate the side wall of the outer cover 210 and connected to the damping bearing 540. The knob 550 is installed at one end of the shaft 530.

[0052] When the lighting unit 330 is located inside the outer casing 210 above the lower sealing plate 220, in addition to the upper reflector 423 being able to directly project most of the light onto the electrical components on the front inside the casing 110, part of the light projected from the lower reflector 410 onto the top plate 230 will be converted to be projected onto the reflector 520 at the bottom of the top plate 230. The reflector 520 then projects the light onto the electrical components on the front of the casing 110. By rotating the knob 550 at the end of the shaft 530, the rotating knob 550 drives the shaft 530 to rotate, that is, the shaft 530 drives the rear back plate 510 and the reflector 520 at the bottom to rotate, that is, the reflection angle of the light source of the reflector 520 can be slightly adjusted, so that the light reflected from the lower reflector 410 to the reflector 520 is reflected at an adjusted angle to the electrical components in the designated area on the front side of the box shell 110. The area caused by the light reflection is more precise and bright, which can further improve the illumination brightness, making it convenient for operators to inspect and maintain the electrical components on the front side of the box shell 110.

[0053] It should be noted that the specific models and specifications of the above-mentioned battery 310, button switch 320, and illuminating lamp 332 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail. The button switch 320 is electrically connected to the battery 310 and the illuminating lamp 332 respectively. The power supply and principle of the battery 310, button switch 320, and illuminating lamp 332 are clear to those skilled in the art and will not be described in detail here.
