Description

Technical Field

[0001] This utility model relates to the field of speed measuring devices, specifically a high-speed tunnel speed measuring device. Background Technology

[0002] Highways, or expressways for short, are roads specifically designed for high-speed automobile travel. Highway tunnels are also a part of highways. Highways control vehicle access throughout their entire length. They are fully enclosed roads dedicated solely to automobiles, and in order to ensure driving safety, speed limits are generally set for different sections of highways. To serve a supervisory and management function, speed measuring devices, or speed cameras, are usually installed in highway tunnels.

[0003] Existing high-speed tunnel speed measurement devices often have some problems during use. First, they are inconvenient to adjust. After the speed camera is installed in the designated location, it is impossible to readjust its direction and angle of use as needed. When adjustment is required, it needs to be disassembled and reinstalled. Second, there is no automatic cleaning function for the speed camera probe. When vehicles pass by, a lot of dust is raised. Dust adhering to the speed camera probe will affect the clarity of the image and is not conducive to the subsequent use of the speed camera. Utility Model Content

Limiting components 8 are fixedly connected to both sides of the bottom of the mounting plate 1. A cleaning mechanism 9 is provided on the surface of the adjustment box 6. A first fixing block 10 is fixedly connected to the bottom of the turntable 3. A screw 11 is rotatably connected to the surface of the first fixing block 10. A handwheel 12 is fixedly connected to one end of the screw 11. A threaded sleeve 13 is threadedly connected to the surface of the screw 11. An adjustment frame 14 is rotatably connected to both sides of the threaded sleeve 13 via a rotating shaft. The bottom of the adjustment frame 14 is rotatably connected to the adjustment box 6 via a rotating shaft.

[0024] The cleaning mechanism 9 includes a motor 901 and two cleaning brushes 902. The bottom of the motor 901 is fixedly connected to the top of the adjustment box 6. The cleaning brushes 902 are located on the surface of the speed camera body 7. The output end of the motor 901 extends through the inner cavity of the adjustment box 6 and is fixedly fitted with a cam 903. Push plates 904 are provided on both sides of the cam 903. Three first springs 905 are fixedly connected between one side of the push plate 904 and the inner wall of the adjustment box 6. A movable frame 906 is fixedly connected to the surface of the push plate 904. One end of the movable frame 906 extends through the adjustment box 6 and is connected to the cleaning brush 902. The brush 902 is fixedly connected. By setting up the cleaning mechanism 9, the motor 901 can be turned on to drive the cam 903 to rotate. The rotation of the cam 903, in conjunction with the first spring 905, can drive the two push plates 904 to move back and forth. The push plates 904, in conjunction with the moving frame 906, can drive the cleaning brush 902 to move left and right to clean the surface of the speed camera body 7. The direction and angle of use of the speed camera body 7 can be adjusted as needed, thus saving the time of reinstalling the speed camera body 7, which is convenient and quick.

[0025] Reference Figure 1 and Figure 2The limiting component 8 includes a limiting box 801. The tops of the two limiting boxes 801 are fixedly connected to the two sides of the bottom of the mounting plate 1, respectively. A lifting block 802 is provided in the inner cavity of the limiting box 801. One side of the lifting block 802 extends to the outer side of the limiting box 801. A second spring 803 and a plug rod 804 are fixedly connected to the top and bottom of the lifting block 802, respectively. One end of the plug rod 804 extends through the limiting box 801 and into the inner cavity of the insertion hole 4. The top of the second spring 803 is fixedly connected to the inner wall of the limiting box 801. By setting the plug rod 804, it can be inserted into the insertion hole 4 to fix the turntable 3 and prevent the turntable 3 from continuing to rotate. By setting the second spring 803, the lifting block 802 will squeeze the second spring 803 when it moves upward. The design of the second spring 803 can facilitate the lifting block 802 and the plug rod 804 to move downward for reset.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The bottom of the rotating block 2 is rotatably connected to the turntable 3 through a first bearing. The top of the mounting plate 1 has four mounting holes 15. The surface of the screw 11 is fitted with a second fixing block 16. The surface of the screw 11 is rotatably connected to the first fixing block 10 and the second fixing block 16 through the second bearing. By setting the first bearing, the rotation of the turntable 3 can be facilitated, and the stability of the turntable 3 can be improved. By setting the mounting holes 15, it can be used with external bolts to quickly fix the mounting plate 1. By setting the second bearing, the rotation of the screw 11 can be facilitated, and the screw 11 can be supported, improving the stability of the screw 11 in use.

[0027] Reference Figure 1 and Figure 3 The surface of the turntable 3 is fitted with four positioning frames 17. The surface of the positioning frames 17 is fixedly connected to the mounting plate 1. Two slide rails 18 are slidably connected to both sides of the top of the screw sleeve 13. The top of the slide rails 18 is fixedly connected to the bottom of the turntable 3. By setting the positioning frames 17, the range of use of the turntable 3 can be limited, the stability of the turntable 3 can be improved, and the tilting of the turntable 3 can be avoided. By setting the slide rails 18, the range of movement of the screw sleeve 13 can be limited, the stability of the movement of the screw sleeve 13 can be improved, and the tilting of the screw sleeve 13 can be avoided.

[0028] Working principle: The user can install the mounting plate 1 in the designated position by using the external bolts and mounting holes 15. If it is necessary to adjust the usage direction of the speed camera body 7, first adjust the lifting block 802 upwards. The lifting block 802 compresses the second spring 803, and at the same time, the lifting block 802 will drive the insertion rod 804 to move upwards and move out of the insertion hole 4. Then, the turntable 3 can be rotated, and the turntable 3 will drive the speed camera body 7 to rotate. After the adjustment is completed, release the restriction on the lifting block 802, and the second spring 803 will reset. With the cooperation of the lifting block 802, the insertion rod 804 can be driven downwards to insert into the insertion hole 4, fixing the turntable 3 and the speed camera body 7. When it is necessary to adjust the usage angle of the speed camera body 7, the user can use the external bolts and mounting holes 15 to install the speed camera body 7. The screw 11 can be rotated by the handwheel 12. The rotation of the screw 11 can drive the screw sleeve 13 to move for adjustment. The screw sleeve 13 can drive the connecting block 5 and the adjustment box 6 to adjust the angle through the adjustment bracket 14. The adjustment box 6 drives the speed camera body 7 to adjust the operating angle. When it is necessary to clean the surface of the speed camera body 7, the motor 901 can be turned on to drive the cam 903 to rotate. The rotation of the cam 903 can drive the two push plates 904 to move back and forth left and right through the first spring 905. The push plates 904 can drive the cleaning brush 902 to move left and right through the moving bracket 906 to clean the surface of the speed camera body 7, so as to avoid the dust adhering to the surface of the speed camera body 7 from affecting the shooting clarity.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
