Description

[0002] With the complexity and diversity of modern construction environments, the reliability of power supply and the effectiveness of emergency lighting are particularly important. At present, the distribution boxes commonly used on construction sites often lack intelligent management capabilities and cannot monitor the status of power supply in real time, resulting in the failure of emergency lighting equipment to start in time in the event of a power outage, affecting the safety of worker evacuation and construction operations.

[0003] Therefore, in response to the demand for dual power distribution boxes at construction sites, the prior art has designed a distribution system that can realize automatic switching of dual power supplies. When the main power fails, this system can automatically switch to the backup power supply and start the emergency lighting components at the same time, thereby ensuring the continuous operation of the lighting system and the safety of the staff.

[0019] 3. The emergency lighting assembly of the present invention adopts common lamps and backup lamps to cooperate with common power supplies and backup power supplies respectively to form a dual-power dual-lamp lighting system, which overcomes the problem that the startup and response time of the low-voltage backup power supply may be slow. It not only avoids the stroboscopic or flickering phenomenon of high-power lamps caused by the unstable current caused by low-voltage power supply, but also can switch the lamps and power supplies appropriately as needed, thereby saving energy and extending the lighting time when full-power operation is not required.

[0020] 4.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 10 The present invention provides a technical solution: an intelligent emergency distribution box, comprising a base 1, a distribution box 2, a common power terminal 3, a single-pole double-throw switch 31, and a backup power supply group 32. The distribution box 2 is provided with an intelligent control module for opening and closing the single-pole double-throw switch 31, and the single-pole double-throw switch 31 is used to switch between the common power terminal 3 and the backup power supply group 32; the backup power supply group 32 is fixedly arranged at the inner bottom of the distribution box 2, the common power terminal 3 extends from the rear side wall of the distribution box 2 and is connected to the single-pole double-throw switch 31, and the rear side wall of the distribution box 2 is provided with an intelligent control module. An electromagnetic coil 4 is provided, and the electromagnetic coil 4 is sleeved on the common power terminal 3. A lifting rod 16 is slidingly limited at the upper end of the distribution box 2. An emergency lighting component is fixedly provided at the upper end of the lifting rod 16. The lower end of the lifting rod 16 extends into the interior of the distribution box 2 and is connected to a pushing mechanism. The pushing mechanism uses the energized electromagnetic coil 4 as power and drives the emergency lighting component to move up and down; when the common power terminal 3 is normally energized, the lifting rod 16 drives the emergency lighting component to move upward; when the backup power supply group 32 is normally energized, the lifting rod 16 drives the emergency lighting component to move downward.

[0034] Furthermore, the intelligent emergency distribution box 2 can quickly switch between the normal power supply and the backup power supply by adopting a single-pole double-throw switch 31, thereby ensuring that the power supply is switched in time and the emergency lighting components are enabled in the event of a power outage, and the emergency lighting components can adaptively adjust the height according to the supply status of different power supplies, achieving the effect of increasing the high voltage and decreasing the low voltage, thereby maintaining the lighting intensity of the lamp.

[0035] like Figure 2-Figure 5 As shown, the pushing mechanism includes an armature block 5, a limit plate 6, a reset spring 7, a vertical rod 8, a main push column 9, a transverse moving plate 11, an active rack 12, a spur gear 13 and a cylindrical cam 14. The limit plate 6 is slidably installed in the distribution box 2. Two groups of reset springs 7 are symmetrically arranged at the lower end of the limit plate 6. An armature block 5 is arranged between the two groups of reset springs 7. One end of the armature block 5 is fixedly connected to the limit plate 6, and the other end of the armature block 5 is arranged to be in an arc shape that matches the electromagnetic coil 4. The transverse moving plate 11 is slidably installed in the distribution box 2. One side of the transverse moving plate 11 is fixedly connected to the active rack 12. The other side of the transverse moving plate 11 is provided with an inclined slot 10. The main push column 9 is inserted into the inclined slot 10. The main push column 9 is fixedly connected to the vertical rod 8, and the vertical rod 8 is fixedly connected to the upper end surface of the limit plate 6. The active rack 12 is meshed with a spur gear 13, which is coaxially fixedly connected to a cylindrical cam 14. The lower end of the cylindrical cam 14 is limited and rotated with a support plate, which is fixedly connected to the inner wall of the distribution box 2. A toggle rod 15 is slidably inserted in the wheel groove of the cylindrical cam 14, and the toggle rod 15 is fixedly connected to the outer wall of the elevator.

[0036] Furthermore, through the design of the limit plate 6, the return spring 7, the vertical rod 8, the main push column 9, the transverse moving plate 11, the active rack 12, the spur gear 13 and the cylindrical cam 14, on the one hand, the magnetic attraction force of the energized electromagnetic coil 4 on the armature block 5 can be converted into an upward pushing force on the lifting rod 16; on the other hand, when the electromagnetic coil 4 is not energized, the lifting rod 16 can be pulled downward, with a high degree of automation and strong mechanical linkage.

[0037] Specifically, when the single-pole double-throw switch 31 is connected to the common power terminal 3, the electromagnetic coil 4 starts to be energized and a magnetic field is generated around it, thereby attracting the armature block 5 to move closer. The armature block 5 drives the limit plate 6 to move downward, and the limit plate 6 acts on the vertical rod 8, so that the vertical rod 8 also moves downward and acts on the inclined groove 10, so that the transverse moving plate 11 is forced to move toward the direction of the lifting rod 16, and the active rack 12 on the transverse moving plate 11 acts on the spur gear 13, so that the spur gear 13 is forced to drive the cylindrical cam 14 to rotate counterclockwise, and the wheel groove on the cylindrical cam 14 acts on the toggle rod 15, so that the toggle rod 15 is forced to push the lifting rod 16 to move upward, and the position of the lamp holder 18 becomes higher, so that the lighting range of the lamp becomes wider; when the single-pole double-throw switch 31 is connected to the backup power supply group 32 When the electromagnetic coil 4 is no longer energized, the armature block 5 is no longer attracted to approach. At this time, under the rebound force of the return spring 7, the limit plate 6 drives the armature block 5 to move upward, and the limit plate 6 acts on the vertical rod 8, so that the vertical rod 8 also moves upward and acts on the inclined groove 10, so that the transverse moving plate 11 is forced to move in the direction away from the lifting rod 16, and the active rack 12 on the transverse moving plate 11 acts on the spur gear 13, so that the spur gear 13 is forced to drive the cylindrical cam 14 to rotate clockwise, and the wheel groove on the cylindrical cam 14 acts on the toggle rod 15 again, so that the toggle rod 15 is forced to push the lifting rod 16 to move downward. At this time, the position of the lamp holder 18 becomes lower, which makes the lighting range of the lamp smaller, and to a certain extent makes up for the light intensity of the low-power standby lamp 21 under the low-voltage state.

[0038] like Figure 1 as well as Figure 2 As shown, the upper end surface of the base 1 is fixedly connected to the distribution box 2, and the lower end of the base 1 is provided with four groups of pulleys distributed in a rectangular array. This arrangement is convenient for massaging the distribution box 2.

[0039] like Figure 1-4 as well as Figure 6-10 As shown, an emergency lighting assembly is applied to an intelligent emergency distribution box, the emergency lighting assembly includes a mounting frame 17, a lamp holder 18, a shading plate 19, a common lamp 20 and a spare lamp 21, the mounting frame 17 is fixedly arranged on a lifting rod 16, the lamp holder 18 is fixedly arranged on the mounting frame 17, a common lamp 20 and a spare lamp 21 are installed on a side of the lamp holder 18 away from the mounting frame 17, the common lamp 20 is powered by a common power terminal 3, the spare lamp 21 is powered by a spare power group 32, the shading plate 19 is driven by a linkage component and is opened or closed on the lamp holder 18 to change the illumination range.

[0040] Furthermore, the emergency lighting assembly adopts a common lamp 20 and a backup lamp 21 to cooperate with the common power supply and the backup power supply respectively, to form a dual-power supply and dual-lamp lighting system, thereby overcoming the problem that the startup and response time of the low-voltage backup power supply may be slow. It not only avoids the possibility of current instability caused by low-voltage power supply, thereby causing frequent flickering or flickering of high-power lamps, but also can appropriately switch the use of lamps and power supplies as needed, thereby saving energy and extending the lighting time when full-power operation is not required.

[0041] like Figure 6-9 As shown, the shading plate 19 is provided with four groups, which are all limitedly rotatably installed on the front end wall of the lamp holder 18. A driven wheel 22 is fixedly provided in the middle of the rotating end of each group of shading plates 19. The linkage parts include a rotating ring 26, an outer gear 27, a vertical rack 28, an auxiliary spring 29 and a trigger bar 30. The rotating ring 26 is limitedly slidably installed in the lamp holder 18. The rotating ring 26 is provided with four arc grooves 25 distributed in a circular array. A cylindrical pin 24 is inserted in each arc groove 25, and the cylindrical pin 24 is fixedly connected to the pushing tooth plate 23. The push gear plate 23 is meshed with the driven wheel 22, the outer wall of the rotating ring 26 is fixedly provided with an outer gear 27, the outer gear 27 is meshed with the vertical rack 28, the lower end of the vertical rack 28 is fixedly connected with a horizontal bar, the upper end of the horizontal bar is fixedly provided with an auxiliary spring 29, the lower end of the horizontal bar is fixedly connected with a trigger bar 30, the lower end of the trigger bar 30 extends out of the bottom of the lamp holder 18 and is connected to the upper end surface of the distribution box 2. There are no less than six groups of common lamps 20, and the spare lamps 21 are arranged in the center of the multiple groups of common lamps 20.

[0042] Furthermore, by using the rotating ring 26, the outer gear 27, the vertical rack 28, the auxiliary spring 29 and the trigger strip 30 in combination, multiple groups of sunshades 19 can be adaptively opened or closed according to the contact state between the lamp holder 18 and the distribution box 2, so that the lighting range of the lamp can be automatically adjusted according to the type of different lamps. When the commonly used lamp 20 is put into use, the sunshade 19 is expanded outward and the lighting range becomes larger. When the spare lamp 21 is put into use, the sunshade 19 is closed inward and the lighting range becomes smaller, thereby ensuring the consistency of light intensity of different light sources.

[0043] During normal use, when the single-pole double-throw switch 31 is connected to the common power terminal 3, the electromagnetic coil 4 starts to be energized and a magnetic field is generated around it, thereby attracting the armature block 5 to continuously approach, and the armature block 5 drives the limit plate 6 to move downward, and the limit plate 6 acts on the vertical rod 8, so that the vertical rod 8 also moves downward and acts on the inclined groove 10, so that the horizontal moving plate 11 is subjected to force and moves toward the direction of the lifting rod 16, and the active rack 12 on the horizontal moving plate 11 acts on the spur gear 13, so that the spur gear 13 is forced to drive the cylindrical cam 14 to rotate counterclockwise, and the wheel groove on the cylindrical cam 14 acts on the toggle rod 15, so that the toggle rod 15 is forced to push the lifting rod 16 to move upward, and the position of the lamp holder 18 becomes higher, so that the lighting range of the lamp becomes wider; at the same time, the common lamp 20 is powered by the common power terminal 3, and at this time, the four sets of sunshades 19 are in an outwardly unfolded state, further expanding the lighting range of the lamp, and at this time the light intensity is soft and the light amplitude is wide;

[0044] When the normal power supply is cut off, the intelligent control module automatically turns on the single-pole double-throw switch 31, so that when the single-pole double-throw switch 31 is connected to the backup power supply group 32, the electromagnetic coil 4 is no longer energized, and thus no longer attracts the armature block 5 to approach. At this time, under the rebound force of the reset spring 7, the limit plate 6 drives the armature block 5 to move upward, and the limit plate 6 acts on the vertical rod 8, so that the vertical rod 8 also moves upward and acts on the inclined groove 10, so that the transverse moving plate 11 is forced and moves in the direction away from the lifting rod 16, and the active rack 12 on the transverse moving plate 11 acts on the spur gear 13, so that the spur gear 13 is forced to drive the cylindrical cam 14 to rotate clockwise, and the wheel groove on the cylindrical cam 14 acts on the toggle rod 15 again. The toggle rod 15 is forced to push the lifting rod 16 to move downward. At this time, the position of the lamp holder 18 becomes lower, which makes the lighting range of the lamp smaller, and to a certain extent compensates for the light intensity of the small-power standby lamp 21 under the low-voltage state; at the same time, the trigger bar 30 on the top of the lamp holder 18 is squeezed by the top of the distribution box 2, so that the vertical rack 28 is forced to move upward, and the vertical rack 28 acts on the outer gear 27 to make the rotating ring 26 rotate, and the arc groove 25 on the rotating ring 26 acts on the cylindrical pin 24, so that the cylindrical pin 24 is forced to push the tooth plate 23 to extend outward, so that the driven wheel 22 drives the shading plate 19 to deflect inward, thereby further gathering the light of the standby lamp 21, thereby ensuring the light intensity of the standby lamp 21.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
