Description

Technical Field

[0001] The present application relates to the field of traffic flow prediction devices, and in particular to an urban traffic flow prediction device. Background Art

[0002] Traffic flow refers to the continuous flow of cars on a road, and more broadly, it also includes the flow of other vehicles and pedestrians. Over a certain period of time, on sections of road unaffected by cross-traffic, traffic flow is continuous. However, at intersections with traffic lights, traffic flow becomes intermittent. Traffic flow needs to be monitored and predicted using prediction devices.

[0003] Existing traffic flow prediction devices have problems such as cumbersome installation process, heavy workload for workers, inconvenient angle adjustment and inconvenient disassembly after installation, resulting in low efficiency in installation, adjustment and disassembly of traffic flow prediction devices.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing traffic flow prediction devices have the problem of low efficiency in installation, adjustment and disassembly. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides an urban traffic flow prediction device.

[0006] This application provides an urban traffic flow prediction device, which adopts the following technical solutions:

[0007] A device for predicting urban traffic flow, comprising a mounting plate, a rotation adjustment mechanism arranged on the mounting plate, a camera connected to the rotation adjustment mechanism, a clamping mechanism and a clamping plate arranged on the mounting plate; a clamping groove is provided on the clamping plate, the clamping mechanism comprises an electric telescopic rod connected to the mounting plate, a mounting rod connected to the electric telescopic rod, a mounting block connected to the mounting rod, a clamping block slidably connected to the mounting block, and an adjustment component arranged in the mounting rod for controlling the extension and retraction of the clamping block; the number of the clamping mechanisms is multiple, and the multiple clamping mechanisms are symmetrically distributed on opposite sides of the mounting plate.

[0008] By adopting the above technical solution, the staff inserts the mounting block and the clamping block into the clamping slot. The adjustment assembly drives the clamping block to extend out of the mounting block. The clamping block limits the mounting block, thereby connecting the clamping plate to the clamping mechanism. The electric telescopic rod drives the clamping plate to move, so that the clamping plate and the mounting plate are clamped and fixed in the installation position, thereby completing the rapid installation of the camera. The clamping plate and the clamping mechanism can be separated by controlling the clamping block to retract into the mounting block by the adjustment assembly, thereby achieving rapid disassembly of the camera. The rotation angle of the camera can be adjusted by rotating the adjustment mechanism. The above structure improves the efficiency of camera installation, adjustment, and disassembly.

[0009] Preferably, the mounting block is provided with a mounting slide, the clamping block is slidably connected to the mounting slide, the mounting rod is provided with a mounting cavity connected to the mounting slide, and the adjusting assembly includes an adjusting rod arranged in the mounting cavity, a connecting rod with one end hinged to the adjusting rod, and a tension spring, the connecting rod is hinged to the clamping block at one end away from the adjusting rod, one end of the tension spring is connected to the adjusting rod, and the other end is connected to the mounting block, a limiting rod is provided on the adjusting rod, and a limiting groove connected to the mounting cavity is provided on the mounting rod, the limiting rod is away from the adjusting rod and one end passes through the limiting groove, the limiting rod is slidably connected to the limiting groove, and the sliding direction of the clamping block is perpendicular to the sliding direction of the limiting rod.

[0010] By adopting the above technical solution, the tension spring drives the adjustment rod toward the mounting block, which in turn drives the connecting rod to move. The connecting rod pushes the clamping block out of the mounting slot, thereby achieving the clamping connection between the clamping block and the clamping slot, thereby enabling the camera to be installed. When the camera needs to be removed, the staff can push the limit rod away from the mounting block. The limit rod drives the adjustment rod away from the mounting block, causing the connecting rod to retract the clamping block into the mounting slot, thereby separating the clamping mechanism from the clamping plate and enabling the camera to be removed.

[0011] Preferably, the rotation adjustment mechanism includes a connecting block rotatably connected to the mounting plate, a first gear is provided on the connecting block, a first motor is provided on the mounting plate, a transmission shaft of the first motor is fixedly connected to a second gear, the second gear is engaged with the first gear, a second motor is provided at one end of the connecting block away from the mounting plate, the second motor is connected to the camera, and the rotation direction of the second motor is perpendicular to that of the first motor.

[0012] Preferably, the transmission shaft of the second motor is fixedly connected to a rotating rod, one end of the rotating rod away from the second motor is rotatably connected to the connecting block, and the camera is connected to the rotating rod.

[0013] By adopting this technical solution, the first motor drives the second gear, which in turn drives the first gear, which in turn drives the connecting block, thereby achieving camera angle adjustment. The second motor drives the rotating rod, which in turn drives the camera, further expanding the camera's angle adjustment range.

[0014] Preferably, a first guiding inclined surface is provided at one end of the clamping block away from the connecting rod, and a second guiding inclined surface is provided at the opening of the clamping groove.

[0015] By adopting the above technical solution, the provision of the first guiding bevel and the second guiding bevel improves the connection efficiency between the clamping block and the clamping slot, thereby improving the installation efficiency of the camera.

[0016] Preferably, a first clamping groove is provided on the mounting plate, and a second clamping groove is provided on the clamping plate, and both the first clamping groove and the second clamping groove are arc-shaped structures.

[0017] Preferably, anti-slip pads are provided in both the first clamping groove and the second clamping groove.

[0018] By adopting the above technical solution, the setting of the first clamping groove and the second clamping groove increases the contact area between the mounting plate and the clamping plate and the mounting position, thereby improving the installation stability of the camera, and the setting of the anti-slip pad further improves the installation stability of the camera.

[0019] Preferably, a plurality of positioning rods are provided on the mounting plate, a plurality of positioning holes are opened on the clamping plate, and the positioning rods are slidably connected to the positioning holes.

[0020] By adopting the above technical solution, the positioning rod passes through the positioning hole, so that the clamping groove on the clamping plate is aligned with the clamping block and the mounting block, thereby further improving the installation efficiency of the camera.

[0021] In summary, this application has the following beneficial technical effects:

[0022] 1. The adjustment component drives the clamping block to engage or disengage with the clamping slot to quickly install or remove the camera.

The end of the rotating rod 26 away from the second motor 25 is rotatably connected to the connecting block 21 via a bearing. The camera 3 is fixedly connected to the rotating rod 26.

[0033] The mounting block 43 defines a mounting slot 431, the engaging block 44 is slidably connected to the mounting slot 431, and the mounting rod 42 defines a mounting cavity 421 that communicates with the mounting slot 431. The adjustment assembly 6 includes an adjustment rod 61 disposed in the mounting cavity 421, a connecting rod 62 hinged at one end to the adjustment rod 61, and a tension spring 63. The end of the connecting rod 62 away from the adjustment rod 61 is hinged to the engaging block 44. One end of the tension spring 63 is fixedly connected to the adjustment rod 61, and the other end is fixedly connected to the mounting block 43. A limiting rod 64 is fixedly provided on the adjustment rod 61. The mounting rod 42 defines a limiting slot 422 that communicates with the mounting cavity 421.

The sliding direction of the engaging block 44 is perpendicular to the sliding direction of the limiting rod 64.

[0034] In the embodiment of the present application, two clamping blocks 44 are provided in the installation slot 431 , and the two clamping blocks 44 are symmetrically arranged on opposite sides of the installation slot 431 .
