Description

Technical Field

[0001] This utility model relates to the field of urban transportation, and in particular to a traffic flow monitoring device. Background Technology

[0002] With the continuous improvement of urban transportation networks, traffic flow monitoring has become a crucial link in traffic management, road condition optimization, and accident early warning. Currently, the mainstream monitoring methods mostly rely on fixed devices equipped with surveillance cameras. However, existing traffic flow monitoring devices have significant shortcomings: Firstly, the installation angle of surveillance cameras is mostly fixed. If the monitoring direction needs to be adjusted to adapt to different road sections (such as turning lanes at intersections or widening areas of the road), the device often needs to be disassembled and reassembled, which is cumbersome and affects the continuity of monitoring. Secondly, the cables connecting the camera to the power supply are often exposed to the external environment and are subject to long-term corrosion from wind, rain, ultraviolet rays, and vehicle exhaust, which can easily lead to aging and damage, resulting in frequent device malfunctions. Utility Model Content

[0003] The purpose of this invention is to provide a traffic flow monitoring device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a traffic flow monitoring device, comprising a pole, an installation unit mounted on the top of the pole, the installation unit consisting of an installation cylinder and a limiting plate, the installation cylinder being rotatable relative to the pole, and the position of the installation cylinder being fixed by the limiting plate, monitoring cameras being provided on both sides of the installation cylinder, and a fixed bracket being fixedly installed between the bottom of the monitoring camera and the installation cylinder; A cable is inserted inside the fixed bracket. One end of the cable is connected to a monitoring camera. A connection port is opened on the outside of the pole. The other end of the cable extends into the mounting cylinder, enters the pole through the connection port, and is connected to an external power source.

[0005] Preferably, a rotating ring is embedded at the top of the mounting cylinder, a rotating groove is formed on the outer side of the top of the rod, and the rotating ring is rotatably disposed on the inner wall of the rotating groove.

[0006] Preferably, the bottom of the mounting cylinder is equipped with a plurality of positioning posts, and the plurality of positioning posts are distributed in a circumferential array.

[0007] Preferably, the limiting plate includes a plate body and a positioning ring, the positioning ring is slidably disposed on the inner wall of the plate body, and a plurality of positioning holes adapted to the positioning posts are provided above the positioning ring.

[0008] Preferably, a pull rod is fixedly connected to the lower part of the positioning ring, and the bottom end of the pull rod extends downward through the disc body.

[0009] Preferably, a plurality of return springs are fixedly connected between the lower part of the positioning ring and the inner bottom wall of the disc.

[0010] The technical effects and advantages of this utility model are as follows: 1. This traffic flow monitoring device achieves smooth rotation of the mounting cylinder relative to the pole by engaging the rotating ring at the top of the mounting cylinder with the rotating groove at the top of the pole. This, in turn, drives the monitoring cameras connected to the fixed brackets on both sides to adjust their angles synchronously. At the same time, the positioning hole of the positioning ring in the limit plate matches the positioning post at the bottom of the mounting cylinder. Combined with the automatic reset function of the return spring, simply pulling down the lever unlocks the rotation and releases it to automatically lock it. No special tools are required, which solves the problems of cumbersome adjustment and easy misalignment of existing devices. It can flexibly adapt to the monitoring needs of different road sections.

[0011] 2. In this traffic flow monitoring device, the cable of the monitoring camera is plugged into the fixed bracket to avoid direct exposure of the cable; and the cable extends from the inside of the mounting tube to the connection port of the pole, and finally passes into the inside of the pole to connect with the external power supply, forming a fully enclosed cable path, which effectively isolates the cable from wind, rain, ultraviolet rays and external impact, significantly extends the service life of the cable and reduces the probability of device failure.

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model provides, for example Figures 1-2 The traffic flow monitoring device shown includes a pole 1, with an installation unit 2 installed on the top of the pole 1. The installation unit 2 consists of an installation cylinder 21 and a limiting plate 23. The installation cylinder 21 can rotate relative to the pole 1, and the position of the installation cylinder 21 can be fixed by the limiting plate 23. Monitoring cameras 3 are provided on both sides of the installation cylinder 21, and a fixing bracket 31 is fixedly installed between the bottom of the monitoring camera 3 and the installation cylinder 21. A cable 32 is inserted inside the fixed bracket 31. One end of the cable 32 is connected to the monitoring camera 3. A connection port 11 is opened on the outside of the pole 1. The other end of the cable 32 extends into the mounting cylinder 21, enters the pole 1 through the connection port 11, and is connected to an external power source.

[0016] The cable 32 of the surveillance camera 3 is inserted into the fixed bracket 31 to avoid direct exposure of the cable 32; and the cable 32 extends through the inside of the mounting tube 21 to the connection port 11 of the pole 1, and finally passes into the inside of the pole 1 to connect with the external power supply, forming a fully enclosed wiring path, effectively isolating wind, rain, ultraviolet rays and external impact, significantly extending the service life of the cable 32 and reducing the probability of device failure.

[0017] like Figure 2 As shown, a rotating ring 22 is embedded at the top of the mounting cylinder 21, and a rotating groove is opened on the outer side of the top of the rod 1, and the rotating ring 22 is rotatably mounted on the inner wall of the rotating groove.

[0018] like Figure 3 As shown, multiple positioning posts 211 are installed at the bottom of the mounting cylinder 21, and the multiple positioning posts 211 are distributed in a circular array.

[0019] like Figures 4-5 As shown, the limiting disk 23 includes a disk body 231 and a positioning ring 232. The positioning ring 232 is slidably disposed on the inner wall of the disk body 231, and a plurality of positioning holes 233 adapted to the positioning post 211 are provided above the positioning ring 232.

[0020] A pull rod 234 is fixedly connected to the lower part of the positioning ring 232, and the bottom end of the pull rod 234 extends downward through the disc body 231.

[0021] Multiple return springs 235 are fixedly connected between the lower part of the positioning ring 232 and the inner bottom wall of the disc body 231.

[0022] By engaging the rotating ring 22 at the top of the mounting cylinder 21 with the rotating groove at the top of the rod 1, the mounting cylinder 21 can rotate smoothly relative to the rod 1, thereby driving the monitoring cameras 3 connected to the fixed brackets 31 on both sides to adjust their angles synchronously. At the same time, the positioning hole 233 of the positioning ring 232 in the limit plate 23 matches the positioning post 211 at the bottom of the mounting cylinder 21. Combined with the automatic reset function of the return spring 235, the rotation can be unlocked simply by pulling down the pull rod 234, and it will automatically lock after being released. No special tools are required, which solves the problems of cumbersome adjustment and easy displacement of the existing device, and can flexibly adapt to the monitoring needs of different road sections.

[0023] Working principle: Two surveillance cameras 3 are symmetrically fixed on both sides of the mounting cylinder 21 by fixing brackets 31, ensuring that the camera lenses face the monitoring target. Then, one end of the cable 32 is connected to the power interface of the surveillance camera 3, and the other end is inserted into the mounting cylinder 21 through the reserved channel inside the fixing bracket 31, and then inserted into the cavity inside the pole 1 through the connection port 11 opened on the outside of the pole 1. Finally, it is led out from the bottom of the pole 1 and connected to the external power supply to complete the power supply circuit of the camera.

[0024] When the monitoring angle of the surveillance camera 3 needs to be adjusted, the operator pulls down the lever 234 of the limit plate 23. The lever 234 drives the positioning ring 232 to slide down along the inner wall of the plate 231. At this time, the return spring 235 is compressed, and the positioning hole 233 above the positioning ring 232 disengages from the positioning post 211 at the bottom of the mounting cylinder 21, thus unlocking the rotation function of the mounting cylinder 21. The operator pushes the mounting cylinder 21 to rotate around the axis of the rod part 1. Through the smooth sliding of the rotating ring 22 in the rotating groove, the fixed bracket 31 and the surveillance camera 3 rotate synchronously until the camera lens is aligned with the target monitoring area. After the angle adjustment is completed, the lever 234 is released, the return spring 235 returns to its deformation, and pushes the positioning ring 232 to slide upward, so that the positioning hole 233 on the positioning ring 232 is precisely inserted into the corresponding positioning post 211 at the bottom of the mounting cylinder 21, locking the position of the mounting cylinder 21. At this time, the surveillance camera 3 maintains a fixed angle for traffic flow monitoring.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
