[0021] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0022] Reference Figures 1 to 5 The utility model provides an intelligent traffic signal light, comprising a column 1, a crossbar 3 fixed to the top of the column 1, and a signal light assembly arranged at the end of the crossbar 3, the signal light assembly comprising a first light group 4 and a second light group 5, the inner sides of the first light group 4 and the second light group 5 are both fixedly connected with a mounting plate 6, and the end of the crossbar 3 is also provided with a conversion mechanism matched with the signal light assembly, specifically, as Figure 1 As shown, the first light group 4 and the second light group 5 are respectively arranged on the front and rear sides of the cross bar 3. Under normal circumstances, the first light group 4 is in use and the second light group 5 is used as a backup. When the first light group 4 fails, the first light group 4 and the second light group 5 are driven by the conversion mechanism to rotate and exchange positions, so that the second light group 5 is placed at the front side and used, thereby ensuring that the signal light will not be interrupted and the road traffic will not be affected.

[0023] like Figure 2 As shown, further, the conversion mechanism in the utility model includes a conversion head 8 rotatably arranged at the end of the cross bar 3, a first limit rod 9 fixedly connected to the outside of the conversion head 8, and a second limit rod 14 fixedly connected to the outside of the cross bar 3. The mounting plate 6 is a semicircular shape that matches the conversion head 8. A limit groove 10 that matches the first limit rod 9 and the second limit rod 14 is opened on the inner side of the mounting plate 6. The length of the limit groove 10 is smaller than the first limit rod 9, and a groove 11 is opened on one side of the mounting plate 6. Specifically, four first limit rods 9 and four second limit rods 14 are symmetrically arranged on both sides, and all of them have I-shaped cross-sections. Since the length of the limit groove 10 is smaller than the first limit rod 9, when the mounting plate 6 is installed with the conversion head 8, the limit groove 10 is only slidably connected to the first limit rod 9, and the groove 11 on one side forms a certain space between the mounting plate 6 and the second limit rod 14, thereby preventing the second limit rod 14 from hindering the movement of the mounting plate 6. Therefore, when the conversion head 8 rotates, the mounting plate 6 can rotate with the conversion head 8 to adjust the position of the first lamp group 4 and the second lamp group 5.

[0024] like Figure 2 , Figure 3 As shown, further, in the utility model, one end of the conversion head 8 is fixedly connected to a shaft rod 15, and the shaft rod 15 is rotatably arranged on the inner side of the cross bar 3 through a bearing, and a rotating cylinder 16 is fixedly connected to the inner side of the cross bar 3, and the output shaft of the rotating cylinder 16 is coaxially fixedly connected to the shaft rod 15. Specifically, the shaft rod 15 is driven to rotate by the rotating cylinder 16, and the shaft rod 15 drives the conversion head 8 to rotate, and the rotating cylinder 16 rotates 180 degrees each time, so that the first lamp group 4 and the second lamp group 5 exchange positions front and back.

[0025] like Figure 2 As shown, further, in the utility model, a positioning groove 12 is provided inside the groove 11, a positioning block 13 matching the positioning groove 12 is fixedly connected to the front side of the cross bar 3, a driving block 20 matching the positioning groove 12 is slidably provided inside the cross bar 3, the driving block 20 is connected with a linear moving component, and the outer sides of the positioning block 13 and the driving block 20 are both arc surfaces matching the positioning groove 12. Specifically, the first lamp group 4 on the front side can be limited by the engagement of the positioning groove 12 with the positioning block 13, and the driving block 20 can be moved along the length direction of the cross bar 3 through the linear moving component, and the driving block 20 is engaged in the positioning groove 12 of the second lamp group 5, so that the second lamp group 5 can be pulled to move, and the second lamp group 5 is moved to a position close to the column 1, which is convenient for maintenance personnel to perform maintenance.

[0026] like Figure 3 , Figure 4 , Figure 5 As shown, further, the linear motion assembly in the utility model includes a lead screw 18 rotatably arranged on the inner side of the cross bar 3, a threaded sleeve 17 sleeved on the outer side of the lead screw 18, and a motor 19 arranged at one end of the lead screw 18. The side wall of the cross bar 3 is provided with a limiting slide groove 7 matched with a driving block 20. The driving block 20 is T-shaped, and one end of the driving block 20 is placed on the outer side of the cross bar 3, and the other end is fixedly connected to the threaded sleeve 17. Specifically, both sides of the lead screw 18 are rotatably connected with a bearing seat, the bearing seat is fixedly connected to the inner side of the cross bar 3, and the motor 19 is fixedly connected to the inner side of the cross bar 3. The lead screw 18 can be driven to rotate by the motor 19, and the threaded sleeve 17 cannot be rotated due to the restriction of the driving block 20. Therefore, the rotation of the lead screw 18 will drive the threaded sleeve 17 to move along the axial direction of the lead screw 18, thereby driving the driving block 20 to move.

[0027] like Figure 1 As shown, further, an electric control box 2 is installed on the outer side of the center column 1 of the utility model. Specifically, a PLC controller is arranged in the electric control box 2, and each signal light of the first light group 4 and the second light group 5 is electrically connected to the PLC controller, and the motor 19 and the rotary cylinder 16 are also electrically connected to the PLC controller. When the signal light fails, the PLC controller will start the rotary cylinder 16 to switch the first light group 4 and the second light group 5, and start the second light group 5. It should be noted that the automatic control of electrical components by the PLC controller is a prior art known to those skilled in the art, so its working principle will not be described in detail.

[0028] Working principle: When the first lamp group 4 in normal use fails, the electric control box 2 starts the rotating cylinder 16 to rotate it 180 degrees, and the rotating cylinder 16 drives the conversion head 8 to rotate, so that the first lamp group 4 and the second lamp group 5 exchange positions. At the same time, the electric control box 2 starts the second lamp group 5, so that it is placed at the front side for traffic control, thereby avoiding interruption of the use of the signal light. When maintenance personnel need to maintain the faulty first lamp group 4, they start the motor 19 through the electric control box 2 to drive the threaded sleeve 17 to move, and drag the first lamp group 4 to a position close to the column 1 through the drive block 20, so as to facilitate maintenance by maintenance personnel. After the maintenance is completed, the first lamp group 4 can be reset by the cooperation of the linear moving component and the drive block 20. At this time, the first lamp group 4 can be moved to the front side for use through the conversion head 8, or it can be placed at the back side as a backup.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
