Description

Technical Field

[0001] This utility model relates to the field of road traffic flow monitoring technology, and in particular to a novel portable road traffic flow monitoring device. Background Technology

[0002] Road traffic flow data is a crucial foundation for traffic planning and management. Traffic flow monitoring helps identify congested and accident-prone road sections, enabling targeted measures to reduce accidents. For example, on highways, traffic flow data collected by monitoring equipment can be used to analyze accident-prone areas and develop corresponding preventative measures.

[0003] In existing technologies, traffic flow monitoring devices are needed to cope with short-term traffic demands or special situations, such as traffic accidents, natural disasters, and large-scale events. However, most existing traffic flow monitoring devices are fixed installations with poor overall mobility, which is not convenient for temporary monitoring of traffic accidents, natural disasters, and large-scale events. Therefore, we propose a new type of portable road traffic flow monitoring device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel portable road traffic flow monitoring device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-4 As shown, a novel portable road traffic flow monitoring device is disclosed, comprising a base 1, with multiple foot holes on the outer wall of the base 1, a docking sleeve 2 fixedly connected to the top of the base 1, a support column 3 threadedly connected to the inner wall of the docking sleeve 2, a T-shaped groove on the top of the support column 3, a T-shaped column 4 rotatably connected to the inner wall of the T-shaped groove, and a vertical sleeve 5 fixedly connected to the top of the T-shaped column 4, the vertical sleeve 5 rotating through the T-shaped column 4 and the T-shaped groove.

[0023] The outer wall of the vertical sleeve 5 is fixedly fitted with a first ring 6, and the support column 3 is slidably fitted with a second ring 7. The outer walls of the first ring 6 and the second ring 7 are both fixedly connected with ring teeth 8. The inner wall of the vertical sleeve 5 is slidably connected with a rectangular rod 12. The outer wall of the rectangular rod 12 is provided with multiple through holes 13. The rectangular rod 12 moves up and down along the inner wall of the vertical sleeve 5. The inner cavity of the vertical sleeve 5 is rectangular.

[0024] The bottom of the second ring 7 is provided with a rotation limiting mechanism, which includes a T-shaped sleeve 9. The bottom of the second ring 7 is fixedly connected to the top of the T-shaped sleeve 9. A rectangular sleeve 10 is fixedly sleeved on the outer wall of the support column 3. The inner wall of the rectangular sleeve 10 is slidably connected to the outer wall of the T-shaped sleeve 9. The T-shaped sleeve 9 can only move up and down inside the rectangular sleeve 10.

[0025] A spring 11 is fitted on the outer wall of the support column 3. The top of the spring 11 is fixedly connected to the bottom of the T-shaped sleeve 9, and the bottom of the spring 11 is fixedly connected to the inner wall of the rectangular sleeve 10. The spring 11 provides support for the T-shaped sleeve 9 and the second ring 7.

[0026] The top of the vertical sleeve 5 is provided with a support mechanism, which includes two round sleeves 16. The outer wall of the vertical sleeve 5 is provided with a threaded hole, and the inner wall of the threaded hole is threaded with a bolt 14. One end of the bolt 14 is located inside one of the through holes 13. The bolt 14 fixes the rectangular rod 12 inside the vertical sleeve 5. The height of the rectangular rod 12 can be adjusted through multiple through holes 13.

[0027] A connecting rod 15 is fixedly connected to the top of the rectangular rod 12. The outer wall of the connecting rod 15 is slidably connected to the inner wall of the two circular sleeves 16. The outer walls of the two circular sleeves 16 are fixedly connected to the same microwave traffic flow monitor 18 (SM-SDCLL-5G). The microwave traffic flow monitor 18 (SM-SDCLL-5G) transmits frequency-modulated microwaves to the road surface through a transmitting antenna. These microwaves are reflected back after being blocked by vehicles and are received by a receiver. Through high-speed real-time digital processing and analysis such as filtering and Fourier transform of the echo signal, basic traffic flow information such as traffic flow, occupancy rate, average speed and vehicle type is detected. The top of the connecting rod 15 is provided with a mounting hole. The inner wall of the mounting hole is threadedly connected to a limit post 17. The outer wall of the limit post 17 is pressed against the top of one of the circular sleeves 16.

[0028] Working principle: In use, the base 1 is placed on the ground to support the support column 3 and the microwave vehicle flow monitor 18. The existing foot nails are then driven into the ground through multiple foot holes to increase the stability of the base 1. When it is necessary to adjust the angle or height of the microwave vehicle flow monitor, the second ring 7 is moved downward to overcome the elastic force of the spring 11, thereby disengaging the annular teeth 8 between the first ring 6 and the second ring 7. The vertical sleeve 5 is rotated to drive the rectangular rod 12 and the connecting rod 15 to rotate, which in turn drives the microwave vehicle flow monitor 18 to rotate. To adjust the rotation angle, the bolt 14 is rotated so that one end slides out of the through hole 13, releasing the position fixation of the rectangular rod 12. The rectangular rod 12 moves up and down along the vertical sleeve 5 to change the height adjustment of the microwave vehicle flow monitor 18.

[0029] When carrying, rotate the support column 3 to disengage it from the inside of the docking sleeve 2, release the position fixation between it and the base 1, rotate the bolt 14 to release the position fixation of the rectangular rod 12, slide the rectangular rod 12 out of the vertical sleeve 5, rotate the limiting column 17 to release the pressure on the top of one of the circular sleeves 16, so that the microwave vehicle flow monitor 18 slides out of the connecting rod 15 through the two circular sleeves 16. The whole can be disassembled into multiple parts for easy carrying.

[0030] All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.
