[0050] The present application will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present application, but the embodiments are not intended to limit the present application.

[0051] Reference Figures 1 to 5 As shown, this application discloses an intelligent traffic control signal light, comprising:

[0052] Bracket 1;

[0053] Light box 2 is connected to the top of bracket 1. The interior of light box 2 is hollow and the top is open.

[0054] Signal indicator 3, at least two signal indicator 3 are provided, the two signal indicator 3 are divided into a working light 31 and a spare light 32. The working light 31 extends vertically from the top of the light box 2 and is used to display traffic control signals. The spare light 32 is built into the light box 2.

[0055] Switching component 4 includes a switching motor 41 and a switching shaft 42. The switching motor 41 is fixedly connected to the light box 2, and the switching shaft 42 is connected to the output end of the switching motor 41. The working light 31 and the spare light 32 are both connected to the switching shaft 42.

[0056] When the working light 31 malfunctions, the switching motor 41 drives the switching shaft 42 to rotate. The switching shaft 42 drives the working light 31 and the spare light 32 to rotate synchronously. The working light 31 rotates into the light box 2, and the spare light 32 rotates out to the outside of the light box 2.

[0057] The intelligent traffic control signal light can intelligently switch between the working light 31 and the backup light 32 in a timely manner after the working light 31 fails, so that the backup light 32 can replace the working light 31 to provide traffic signal indication. This avoids pedestrians and oncoming vehicles losing traffic control signals, quickly overcomes the problem of signal light failure, and ensures the smooth and orderly operation of road traffic in the first instance.

[0058] In this embodiment, refer to Figure 3 As shown, preferably, the intelligent traffic control signal light further includes a quick-release component 5, which includes:

[0059] The adapter block 51 is fixedly connected to the switching shaft 42, and the adapter block 51 is provided with a fixing slot 511;

[0060] The first card plate 52 is slidably connected to one end of the signal indicator 3, and the first card plate 52 is provided with a protruding first insertion part 521.

[0061] The second card plate 53 is slidably connected to one end of the signal indicator light 3, and the second card plate 53 is provided with an outwardly protruding second insertion part 531.

[0062] Spring 54 is disposed between the first clamping plate 52 and the second clamping plate 53. Spring 54 is in a stretched state and is used to drive the first clamping plate 52 and the second clamping plate 53 to move closer together.

[0063] The first card plate 52 and the second card plate 53 are symmetrically arranged, and the first insertion part 521 and the second insertion part 531 are respectively inserted into the fixed card slot 511 from both sides of the adapter block 51.

[0064] While ensuring smooth and orderly road traffic in the first instance, the intelligent traffic control signal light, by incorporating quick-release components 5, can effectively shorten maintenance time during subsequent repairs. Specifically, under normal operating conditions, the first locking plate 52 and the second locking plate 53 are pulled and pressed against the adapter block 51 by the elastic force of the spring 54. The first insertion part 521 and the second insertion part 531 are simultaneously inserted into the fixed slot 511 from both sides, thereby securing the signal indicator 3 firmly to the adapter block 51 and preventing the signal indicator 3 from falling off during rotation. When maintenance personnel subsequently disassemble and repair the faulty signal indicator 3, they only need to pull the first locking plate 52 and the second locking plate 53 away from each other, causing the first insertion part 521 and the second insertion part 531 to disengage from the fixed slot 511, thus reducing the difficulty of maintenance and significantly shortening the maintenance time.

[0065] In this embodiment, refer to Figure 4 As shown, preferably, the intelligent traffic control signal light further includes a disassembly component 6, which includes:

[0066] The first drive cylinder 61, the fixed end of the first drive cylinder 61 is connected to the inner wall of the lamp box 2;

[0067] The gripper cylinder 62 has a fixed end connected to the movable end of the first drive cylinder 61. The movable end of the gripper cylinder 62 includes two actuating grippers 621 that can move away from or move closer to the gripper.

[0068] The first drive cylinder 61 is used to drive the gripper cylinder 62 to move closer to or away from the adapter block 51, and the gripper cylinder 62 is used to drive the first clamping plate 52 and the second clamping plate 53 to move away.

[0069] By setting up the disassembly component 6, the disassembly component 6 can replace the manual disassembly of the signal indicator 3 by maintenance personnel, further reducing the maintenance difficulty. Specifically, when the signal indicator 3 to be disassembled is moved to the designated position, the first drive cylinder 61 drives the gripper cylinder 62 to move until the execution gripper 621 of the gripper cylinder 62 moves between the first clamping plate 52 and the second clamping plate 53; then the gripper cylinder 62 drives the two execution grippers 621 to move away, so that the first clamping plate 52 and the second clamping plate 53 can overcome the elastic force of the spring 54 and move away from each other until the first insertion part 521 and the second insertion part 531 are disengaged from the fixed slot 511, thereby completing the disassembly of the signal indicator 3 and the adapter block 51, assisting maintenance personnel in the disassembly operation and further shortening the maintenance time.

[0070] After the faulty signal indicator 3 is disassembled, maintenance personnel need to remove it. To further shorten the maintenance time and avoid maintenance personnel setting up ladders and obstructing the road, in this embodiment, preferably, the intelligent traffic control signal light also includes a receiving component 7, which includes:

[0071] The receiving guide groove 71 is horizontally connected to the inner cavity of the light box 2;

[0072] The first elastic bellows 72 is connected inside the receiving guide groove 71, and one end of the first elastic bellows 72 is sealed.

[0073] The first air pump 73 is connected to the other end of the first elastic bellows 72. The first air pump 73 is used to drive the first elastic bellows 72 to extend or retract within the receiving guide groove 71.

[0074] The receiving platform 74 is connected to the sealing end of the first elastic bellows 72, and the receiving platform 74 is slidably connected to the end of the receiving guide groove 71.

[0075] The second drive cylinder 75, the fixed end of the second drive cylinder 75 is connected to the receiving platform 74;

[0076] Electromagnet receiving plate 76 is connected to the movable end of the second drive cylinder 75, and the second drive cylinder 75 drives the electromagnet receiving plate 76 to move in the vertical direction.

[0077] The first magnetic absorbing piece 77 is connected to both sides of the signal indicator 3. The first magnetic absorbing piece 77 is used to be attracted by the electromagnet receiving plate 76.

[0078] The third drive cylinder 78 has a fixed end that is fixedly connected to the inner wall of the light box 2, and a movable end that is connected to the first drive cylinder 61. The third drive cylinder 78 is used to drive the first drive cylinder 61 to move along the length direction of the receiving guide groove 71.

[0079] The light box 2 has a first inspection port 21 at the end near the bracket 1, and the first elastic corrugated pipe 72 can push the receiving platform 74 to the first inspection port 21.

[0080] By setting up the receiving component 7, the receiving component 7 can receive the disassembled signal indicator 3 and transport it to the position of the first inspection port 21; specifically, when there is a signal indicator 3 that needs to be disassembled, the first air pump 73 is started, the first air pump 73 inflates the first elastic bellows 72, the first elastic bellows 72 gradually extends along the length direction of the light box 2 under the limiting guidance of the receiving guide groove 71, the first elastic bellows 72 drives the receiving platform 74 to slide to the bottom of the signal indicator 3, and then the second drive cylinder 75 drives the electromagnet receiving plate 76 to rise and abut against one side of the signal indicator 3, the electromagnet receiving plate 76 attracts the first magnetic suction piece 77 and stably supports the signal indicator 3; when the gripper cylinder 62 of the disassembly component 6 drives the first insertion part 5 After the second insertion part 531 disengages from the fixed slot 511, the first elastic bellows 72 continues to extend, and the third drive cylinder 78 drives the disassembly assembly 6 to move as a whole until the first clamping plate 52 and the second clamping plate 53 are completely disengaged from the range of the adapter block 51. Finally, the first drive cylinder 61, the gripper cylinder 62 and the third drive cylinder 78 are reset, the second drive cylinder 75 is reset and drives the electromagnet receiving plate 76 to descend, the first air pump 73 continues to inflate, and the first elastic bellows 72 drives the receiving platform 74 to slide until the signal indicator light 3 on the electromagnet receiving plate 76 is moved to the first inspection port 21. The maintenance personnel can then remove the signal indicator light 3 to be repaired from the first inspection port 21, avoiding the situation of traffic congestion caused by occupying the normal road when removing the signal indicator light 3.

[0081] In this embodiment, refer to Figure 1 and Figure 2 As shown, preferably, when the signal indicator lights 3 are provided in multiple sets at different positions, such as the three sets of six signal indicator lights 3 located in the same straight line direction as shown in this embodiment, a transport distance is left between the upper end of the electromagnet receiving plate 76 and the bottom side of the spare light 32 recycled into the light box 2, so as to facilitate the smooth movement of the signal indicator lights 3 to be repaired from the bottom space of the light box 2 to the first inspection port 21.

[0082] Since the signal indicator 3 is set up with multiple signal indicator lights 3, the distance between the farthest signal indicator light 3 and the first inspection port 21 may be more than ten meters, making transportation difficult. However, in this embodiment, by setting up the first air pump 73 and the first elastic bellows 72, the long-distance transportation of the signal indicator light 3 is cleverly realized. This avoids the high cost and difficult installation problems of using linear movement methods such as traditional lead screws and drive cylinders when transporting the signal indicator light 3 over long distances, and ensures the reliable operation of the receiving component 7.

[0083] In this embodiment, preferably, the bracket 1 has a hollow inner cavity and an open top, and the inner cavity of the bracket 1 communicates with the inner cavity of the light box 2. A lifting assembly 8 is provided in the inner cavity of the bracket 1, and the lifting assembly 8 includes:

[0084] A transfer electromagnet 81 is connected to the inner wall of the bracket 1 and is located at the connection between the bracket 1 and the light box 2.

[0085] The second magnetic plucking piece 82 is connected to the back of the signal indicator 3. The second magnetic plucking piece 82 is used to be attracted by the transfer electromagnet 81.

[0086] The lifting platform 83 is slidably connected to the inner wall of the support 1;

[0087] The second elastic bellows 84 has one end sealed and the sealed end connected to the lifting platform 83, and the other end connected to the bottom end of the bracket 1.

[0088] The second air pump 85 is connected to one end of the second elastic bellows 84 near the bottom of the bracket 1. The second air pump 85 is used to drive the second elastic bellows 84 to extend or retract within the bracket 1.

[0089] The support 1 has a second inspection port 11 on its side wall, and the second elastic corrugated pipe 84 can support the lifting platform 83 to move to the second inspection port 11.

[0090] By setting up the lifting assembly 8, maintenance personnel can retrieve the signal indicator light 3 to be repaired from the second inspection port 11, which is relatively close to the ground. This avoids the need for maintenance personnel to climb or use ladders for high-altitude work, further reducing the difficulty of maintenance and facilitating operation. Specifically, after the first flexible bellows 72 pushes the signal indicator light 3 to be repaired to the first inspection port 21, the transfer electromagnet 81 attracts the second magnetic plate 82, and the receiving assembly 7 is reset. Then, the second air pump 85 inflates the second flexible bellows 84, which extends and drives the lifting platform 83 to rise until the lifting platform 83 moves to the position of the transfer electromagnet 81. The transfer electromagnet 81 is then de-energized, and the signal indicator light 3 to be repaired is placed on the lifting platform 83. Finally, the second flexible bellows 84 retracts until the lifting platform 83 moves to the second inspection port 11, where maintenance personnel can open the second inspection port 11 to retrieve the signal indicator light 3 to be repaired.

[0091] In this embodiment, refer to Figure 5 As shown, preferably, the lifting assembly 8 also includes a rotary motor 86, which is connected to the inner side wall of the bracket 1 and is connected to the transfer electromagnet 81. The rotary motor 86 is used to drive the transfer electromagnet 81 to rotate.

[0092] When the transfer electromagnet 81 attracts the second magnetic clasp 82, the rotary motor 86 drives the transfer electromagnet 81 and the signal indicator light 3 to be maintained to rotate, which can rotate the horizontal signal indicator light 3 to a vertical position, thereby reducing the width of the bracket 1 and reducing the manufacturing cost of the bracket 1.

[0093] In this embodiment, refer to Figure 2 As shown, preferably, the lifting assembly 8 also includes a barrier 87, which is connected to the lifting platform 83.

[0094] By setting up a barrier 87, which surrounds the signal indicator light 3 on the lifting platform 83, the signal indicator light 3 is prevented from falling off, thus improving the reliability of lifting and transportation. Furthermore, the interior of the barrier 87 can also be set with a recessed limiting structure that matches the signal indicator light 3, thereby improving stability.

[0095] In this embodiment, preferably, the intelligent traffic control signal light also includes a protective component 9. The protective component 9 includes a protective cover plate 91 and a protective drive cylinder 92. The protective cover plate 91 covers the top opening of the light box 2. The fixed end of the protective drive cylinder 92 is connected to the light box 2, and the movable end of the protective drive cylinder 92 is connected to the protective cover plate 91. The protective drive cylinder 92 is used to drive the protective cover plate 91 to move.

[0096] By setting up the protective component 9, the protective shielding effect on the inside of the light box 2 is improved. Specifically, when the signal indicator 3 switches between the working light 31 and the standby light 32, the protective drive cylinder 92 drives the protective cover 91 to open, so that the signal indicator 3 can rotate and switch. After the switching is completed, the protective drive cylinder 92 drives the protective cover 91 to close, thereby improving the protection capability.

[0097] Preferably, the intelligent traffic control signal light also includes multiple sensors (not shown in the figure) for detecting the movement of the signal indicator 3 under maintenance inside the light box 2 and the bracket 1.

[0098] In this embodiment, preferably, the intelligent traffic control signal light also includes a controller (not shown in the figure), which is used to issue traffic control signals. Preferably, the circuit connection between the working light 31, the spare light 32 and the controller can be a male and female plug connection method (not shown in the figure), which facilitates insertion and disconnection. Specifically, a driving component such as a cylinder can be used to drive the male and female plugs to move, thereby realizing the connection or disconnection of the circuit.

[0099] The implementation principle of this application embodiment is as follows: The intelligent traffic control light is equipped with a working light 31 and a backup light 32. When the working light 31 malfunctions, the switching component 4 can rotate and switch the working light 31 and the backup light 32 immediately, so that the backup light 32 can start working and provide traffic signal indication, ensuring the smooth and orderly operation of road traffic; the signal indicator light 3 to be repaired and returned to the light box 2 can be quickly removed through the cooperation of the quick-release component 5 and the disassembly component 6; through the cooperation of the receiving component 7 and the lifting component 8, the signal indicator light 3 to be repaired can be automatically moved to the position of the second inspection port 11, further reducing the difficulty of subsequent maintenance and disassembly and shortening the maintenance time.

[0100] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
