[0027] The invention is further described below with reference to the accompanying drawings and specific embodiments:

[0028] See also Figure 1-4 According to an embodiment of the present invention, a traffic flow control device for a road intersection includes an intersection 1 and four traffic lights 4. A top frame 3 is provided above the intersection 1, and a moving mechanism 5 for driving the traffic lights 4 to move is provided on the top frame 3;

[0029] The moving mechanism 5 includes a guide rail groove 51 provided below the top frame 3. Two first bidirectional screw rods 52 and two second bidirectional screw rods 56 are installed inside the guide rail groove 51. The two first bidirectional screw rods 52 are distributed in parallel, and the two second bidirectional screw rods 56 are distributed in parallel. The two first bidirectional screw rods 52 and the two second bidirectional screw rods 56 form a square shape. The threads at both ends of each first bidirectional screw rod 52 are threadedly connected to a first slider 53. The first sliders 53 are grouped in twos. A traffic light 4 for controlling different directions is provided below each group of first sliders 53. The threads at both ends of each second bidirectional screw rod 56 are threadedly connected to a second slider 57. The second sliders 57 are grouped in twos. A traffic light 4 for controlling different directions is provided below each group of second sliders 57.

[0030] The rotation of the first bidirectional screw rod 52 can simultaneously drive a set of first sliders 53 to approach each other, thereby driving two sets of traffic lights 4 in opposite directions to approach each other. The rotation of the second bidirectional screw rod 56 can simultaneously drive a set of second sliders 57 to approach each other, thereby driving another two sets of traffic lights 4 in opposite directions to approach each other, so that drivers can clearly see the instructions of the traffic lights 4 in foggy weather or other low visibility weather.

[0031] The top frame 3 is also provided with a driving mechanism 6 for driving the first bidirectional screw rod 52 and the second bidirectional screw rod 56 to rotate, thereby enabling the position of the traffic light 4 to be adjusted;

[0032] The driving mechanism 6 can drive the first bidirectional screw rod 52 and the second bidirectional screw rod 56 to rotate, thereby adjusting the position of the traffic light 4 .

[0033] like Figure 1 As shown, the top frame 3 is fixed to the ground through the support columns 2, and the support columns 2 can support the top frame 3 to ensure its stability.

[0034] like Figure 3 As shown, the first slider 53 is slidably connected to the inside of the guide rail groove 51, and a vertical rod 54 is provided below each group of first sliders 53. A first mounting plate 55 is fixedly installed at the bottom end of the vertical rod 54, and a traffic light 4 is installed at the bottom end of the first mounting plate 55; the second slider 57 is slidably connected to the inside of the guide rail groove 51, and a second mounting plate 58 is provided below each group of second sliders 57, and a traffic light 4 is installed at the bottom end of the second mounting plate 58;

[0035] The four traffic lights 4 are arranged in groups of two. The vertical rods 54 can be used to stagger the two groups of traffic lights 4 so as to avoid mutual interference when the two groups of traffic lights 4 move.

[0036] like Figure 3 and 4As shown, the driving mechanism 6 includes four groups of transmission rods 61 installed inside the top frame 3, and the two ends of each group of transmission rods 61 are respectively connected to the first bevel gear 62 and the second bevel gear 63, and the middle position of the first bidirectional screw rod 52 and the second bidirectional screw rod 56 is installed with a third bevel gear 64, and the second bevel gear 63 is meshed with the third bevel gear 64; four groups of stable seats 68 are installed inside the top frame 3, and the transmission rods 61 are connected to the stable seats 68 through rotation; the driving mechanism 6 also includes a motor box 67 fixedly installed on the top of the top frame 3, and a motor 66 is installed inside the motor box 67. The output end of the motor 66 is installed with a fourth bevel gear 65, and the fourth bevel gear 65 is meshed with the third bevel gear 64;

[0037] The fourth bevel gear 65 is driven to rotate by the motor 66, the fourth bevel gear 65 drives the first bevel gear 62 to rotate, the first bevel gear 62 drives the transmission rod 61 to rotate, the transmission rod 61 drives the second bevel gear 63 to rotate, the second bevel gear 63 drives the third bevel gear 64 to rotate, and multiple groups of third bevel gears 64 respectively drive the first bidirectional screw rod 52 and the second bidirectional screw rod 56 to rotate, thereby realizing the adjustment of the position of the traffic light 4.

[0038] like Figure 3 As shown, connecting seats 7 are fixedly installed at the four corners of the guide rail groove 51, and the top end of the support column 2 is connected to the connecting seat 7.

[0039] The working principle of the traffic flow control device at a road intersection in the present invention is as follows: when heavy fog or other weather with low visibility occurs, the starting motor 66 drives the fourth bevel gear 65 to rotate, the fourth bevel gear 65 drives the first bevel gear 62 to rotate, the first bevel gear 62 drives the transmission rod 61 to rotate, the transmission rod 61 drives the second bevel gear 63 to rotate, the second bevel gear 63 drives the third bevel gear 64 to rotate, and multiple groups of third bevel gears 64 respectively drive the first bidirectional screw rod 52 and the second bidirectional screw rod 56 to rotate. The rotation of the first bidirectional screw rod 52 can simultaneously drive a group of first sliders 53 to approach each other, and then can drive the two groups of traffic lights 4 in opposite directions to approach each other. The rotation of the second bidirectional screw rod 56 can simultaneously drive a group of second sliders 57 to approach each other, and then can drive the other two groups of traffic lights 4 in opposite directions to approach each other, so that the driver can see the instructions of the traffic lights 4 clearly in foggy weather or other weather with low visibility.
