Abstract
Description
Technical Field
[0001] This utility model relates to the field of road early warning technology, specifically a road merging and diverging early warning safety guidance system detected by millimeter-wave radar. Background Technology
[0002] Highways are relatively closed driving areas. On basic sections, traffic flow is relatively smooth, and the capacity and service level generally meet the design standards. However, in some special sections, such as merging and diverging areas, long downhill slopes, or sharp turns, the probability of accidents increases several times over, posing a great safety hazard to drivers who follow traffic rules.
[0003] For example, patent publication number CN212750093U discloses a real-time traffic flow monitoring and diversion guidance device for highways. Specifically, it includes multiple early warning devices installed on one side of the highway, which are connected to the highway monitoring center system. The early warning devices mainly consist of a diversion information electronic screen, a speed limit sign electronic screen, a millimeter-wave radar, and a monitoring camera. The diversion information electronic screen, speed limit sign electronic screen, millimeter-wave radar, and monitoring camera are all connected to a controller. The controller has a built-in communication module and communicates with the highway monitoring center system through the communication module. This utility model has a simple structure, is easy to use, and can guide the diversion of vehicles behind in real time according to road conditions and monitor road traffic flow in real time.
[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

The movable clamping plate 7 clamps on one side of the highway warning device or intelligent warning guidance light and is U-shaped with the first clamping brackets 3. By locking the first adjusting threaded rod 5, the first limiting nut 6, the second adjusting threaded rod 10, and the second limiting nut 11, the highway warning device or intelligent warning guidance light can be installed. The lamp is clamped and fixed, which can clamp and fix highway warning devices or intelligent warning guidance lights of different sizes. Then, two second clamping frames 4 are placed on the side of the guardrail post. By rotating the third adjusting threaded rod 14, the threads of the third adjusting threaded rod 14 on the inner side of the second sliding groove 13 are symmetrical and opposite. When the third adjusting threaded rod 14 rotates, it drives the two second sliding blocks 12 to move towards each other in the second sliding groove 13. The two second clamping frames 4 are clamped and fixed on the side of the guardrail post. The third limit nut 15 is locked. It can clamp on the side of guardrail posts of different thicknesses, which is convenient for the installation and fixing of highway warning devices or intelligent warning guidance lights. At the same time, it can fix highway warning devices or intelligent warning guidance lights of different sizes, reducing the installation cost of highway warning devices or intelligent warning guidance lights. The shape of the second clamping frame 4 or the first clamping frame 3 can be determined according to the shape of the highway warning device, intelligent warning guidance light and guardrail post in the actual situation.
