Description

Technical Field

[0001] The utility model relates to the technical field of ultra-high detection, and particularly relates to a sensor for ultra-high detection at highway intersections. Background Art

[0002] Generally, ultra-high detection sensors are installed at highway intersections. The ultra-high detection sensor realizes the ultra-high detection of the object to be measured by installing a single-point lidar on the gantry at the highway intersection, configuring the single-point lidar to emit a laser beam, and determining whether the single-point lidar receives a laser echo signal. However, after long-term use, dust will accumulate on the lens of the sensor. When the accumulated dust is thick, it will block the laser signal and affect the measurement. Moreover, the sensor is generally installed at a high place, making it inconvenient to clean. Therefore, a sensor for ultra-high detection at highway intersections is proposed. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a sensor for ultra-high detection at highway intersections, which can effectively solve the problems mentioned in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

A positioning base is provided at the upper end of the sensor body, and a positioning through hole is opened on the positioning base. A sensor lens is provided at the bottom of the sensor body. A positioning mechanism is provided inside the sensor body. The positioning mechanism includes an installation sleeve fixedly installed inside the sensor body. An installation base is fixedly installed at the bottom of the installation sleeve, and an installation screw hole is opened on the installation base. A lifting plate is movably installed inside the installation sleeve. A sliding support foot is fixedly installed on the lifting plate. A spring is provided below the lifting plate inside the installation sleeve. A cleaning mechanism is provided at the sensor lens. The cleaning mechanism includes a light-shielding plate fixed to the lower end of the sensor body and a driving motor fixed to the lifting plate.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] During use, the vehicle height can be detected by the sensor body. When dust accumulates on the sensor lens, the drive motor can be started.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Such as Figure 1 Figure 2As shown in the figure, a sensor for detecting ultra-high at a highway intersection includes a sensor body 1. A positioning base 2 is provided at the upper end of the sensor body 1. A positioning through hole 3 is provided on the positioning base 2. A sensor lens 4 is provided at the bottom of the sensor body 1. A positioning mechanism 5 is provided inside the sensor body 1. A lens mounting opening 603 is provided on the light-shielding plate 601. The sensor lens 4 is connected to the light-shielding plate 601 through the lens mounting opening 603. By the combined use of the positioning mechanism 5 and the cleaning mechanism 6, the sensor lens 4 can be conveniently and quickly cleaned.

[0020] As Figure 3 shown, the positioning mechanism 5 includes a mounting sleeve 501 fixedly installed inside the sensor body 1. A mounting base 502 is fixedly installed at the bottom of the mounting sleeve 501. A mounting screw hole 503 is provided on the mounting base 502. A lifting plate 506 is movably installed inside the mounting sleeve 501. A sliding support foot 505 is fixedly installed on the lifting plate 506. A spring 504 is provided inside the mounting sleeve 501 below the lifting plate 506. A screw is provided in the mounting screw hole 503. The mounting base 502 is fixed inside the sensor body 1 through the screw. A sliding groove is provided on the inner wall of the mounting sleeve 501. The sliding support foot 505 is movably installed inside the mounting sleeve 501 through the sliding groove. One end of the spring 504 is fixed at the bottom of the mounting sleeve 501, and the other end of the spring 504 is fixed at the bottom of the lifting plate 506.

[0021] The driving motor 602 can be installed inside the mounting sleeve 501 through the lifting plate 506. The spring 504 provides elastic force for the lifting plate 506 to make the lifting plate 506 move upward. After the lifting plate 506 moves upward, it will drive the entire cleaning mechanism 6 to move upward, so that the silica gel scraping strip 606 abuts against the sensor lens 4.

[0022] As Figure 4 shown, the cleaning mechanism 6 includes a light-shielding plate 601 fixed to the lower end of the sensor body 1 and a driving motor 602 fixed to the lifting plate 506. The output end of the driving motor 602 is fixedly connected to a driving shaft 604. A positioning frame body 605 is fixedly installed at the lower end of the driving shaft 604. A silica gel scraping strip 606 is fixedly installed on the positioning frame body 605. A lens mounting opening 603 is provided on the light-shielding plate 601. Screws are provided on the lifting plate 506. The driving motor 602 is fixed to the lifting plate 506 through the screws. A coupling is provided at the output end of the driving motor 602. The driving shaft 604 is fixedly connected to the output end of the driving motor 602 through the coupling. The other end of the driving shaft 604 is fixed to the positioning frame body 605. The positioning frame body 605 is movably installed below the sensor lens 4 through the driving shaft 604.

[0023] Specifically, after the silicone squeegee 606 contacts the sensor lens 4, the drive motor 602 can be started. After starting the drive motor 602, it will drive the drive shaft 604 to rotate. After the drive shaft 604 rotates, it will drive the silicone squeegee 606 on the positioning frame 605 to rotate along the sensor lens 4.

[0024] It should be noted that the present utility model is a sensor for ultra-high detection at highway intersections. During actual use, first, the cleaning mechanism 6 is installed on the positioning mechanism 5. Since the sliding feet 505 are movably installed in the mounting sleeve 501 through the chute, one end of the spring 504 is fixed to the bottom of the mounting sleeve 501, and the other end of the spring 504 is fixed to the bottom of the lifting plate 506. After the cleaning mechanism 6 is installed on the positioning mechanism 5, the spring 504 will provide elastic force to the lifting plate 506, causing the lifting plate 506 to move upward. After the lifting plate 506 moves upward, it will drive the entire cleaning mechanism 6 to move upward, making the silicone squeegee 606 contact the sensor lens 4. After the silicone squeegee 606 contacts the sensor lens 4, the drive motor 602 can be started. After starting the drive motor 602, it will drive the drive shaft 604 to rotate. After the drive shaft 604 rotates, it will drive the positioning frame 605 to rotate. After the positioning frame 605 rotates, it will drive the silicone squeegee 606 to rotate along the sensor lens 4, thus facilitating the rapid cleaning of the sensor lens 4.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
