Description

Technical Field

[0001] The invention relates to the technical field of vehicle overspeed detection, in particular to a traffic vehicle overspeed detection device. Background Art

[0002] With the increase in the number of cars, traffic accidents occur frequently, among which speeding is one of the important causes of accidents. Speeding not only increases the braking distance, but also reduces the driver's ability to respond to emergencies. Therefore, it is crucial to establish an effective speeding detection system to ensure road safety. Many countries and regions have formulated clear traffic regulations and stipulated speed limit standards for different sections of roads. The application of speeding detection devices helps law enforcement agencies to better enforce these regulations and maintain traffic order. The development of modern science and technology has greatly improved the accuracy and reliability of speeding detection equipment. The application of radar, laser, video surveillance and other technologies has made real-time monitoring and data processing more efficient and accurate. With the increase in public awareness of traffic safety, society's resistance to speeding behavior has become increasingly obvious, which has promoted the research and development and application of traffic vehicle speeding detection devices in order to improve traffic safety levels and reduce the occurrence of traffic accidents.

[0003] When detecting the speed of a vehicle, devices such as lasers and radars are used to test the speed of the vehicle when the vehicle passes through a set road section, which is similar to the detection method recorded in "CN201010504840.3". In some accident-prone areas or sensitive areas such as schools and hospitals, temporary devices are needed to monitor speeding behavior to improve road safety. This detection method is fixed to the ground and cannot be quickly disassembled. Moreover, when a vehicle violates the law, it is necessary to take a photo of the vehicle to facilitate subsequent punishment. The camera installed on the existing speed measuring device that is easy to disassemble is easily contaminated by dust raised by passing vehicles, resulting in unclear photos taken by the camera. Summary of the invention

[0013] Working principle: install the bottom plate 201 on the ground through the installation hole 202, and install the support column 1 on the roadside. Then, when the vehicle travels on the moving plate 203, the moving plate 203 moves down, thereby touching the induction switch set at the upper end of the first slide bar 205. The front and rear wheels of the vehicle press the moving plate 203 to determine whether the vehicle is speeding. When the vehicle is speeding, the induction switch transmits the signal to the stepper motor and the camera 14 through the line. The stepper motor starts to drive the moving rod 8 to move down. The moving rod 8 drives the dustproof door 13 to move downward to expose the camera. The camera takes a picture of the license plate number of the vehicle. If there is overspeed, no reaction will be performed, thereby reducing dust pollution. When the weather is sunny, the solar panel 11 will collect solar energy and store it in the mobile power supply. When it rains, rainwater will flow into the water tank 10 through the rainwater pipe 12 into the porous pipe, and flow out from the holes to the screen of the camera 14 to clean it. At the same time, rainwater flows from the water tank 10 into the mobile water tank 401 in the drain pipe 9. The mobile water tank 401 moves downward, driving the pulling rope 3, thereby driving the rotating cylinder 501 to rotate. The rotating cylinder 501 rotates and drives the scraping device 5 through the rotating cylinder 501 and the connecting rod 503. 04 scrapes up and down, and the scraper 50402 is closely attached to the screen of the camera through the third spring 50404 and the second slide bar 50403. At this time, when a vehicle is approaching and overspeeding, the dustproof door 13 moves downward and drives the mobile water tank 401 to move downward to the blocking rod through the lower plate 406, and the mobile water tank 401 is dumped at the water outlet to make the rainwater therein flow out. At the same time, the rotating cylinder 501 is driven by the pulling rope 3 to pull the scraper 504 to the highest position to prevent obstruction of the camera screen. At the same time, the lower plate 406 moves downward to drive the connecting long rod 607 to move downward, and the water blocking plate 604 Under the action of the fourth spring 603 and the third sliding bar 602, it moves to the inner surface of the rainwater pipe 12, blocking the rainwater and preventing it from continuing to enter the porous pipe. The rain remaining on the camera screen is also hung to the upper end by the scraper device 504 and flows to both sides, which will not hinder the camera from taking pictures. After taking pictures, the dustproof door 13 moves to its original position under the action of the stepper motor. At this time, the water blocking plate 604 and the limit rod 405 also move to their original positions. At this time, there is no rainwater in the mobile water tank 401. The mobile water tank 401 returns to its original position under the action of the second spring 507, and then repeats the cycle.

[0014] (III) Beneficial effects

[0015] The present invention provides a vehicle speeding detection device, which has the following beneficial effects:

[0016] 1. Through the induction switch in the induction device, the speed of the front and rear wheels of the vehicle can be quickly sensed to determine whether the vehicle is speeding, and the speeding vehicle can be photographed for subsequent analysis, which is convenient to use and saves energy.

[0017] 2. The base plate can be quickly installed through the installation holes set in the sensing device, which is convenient for use in some areas where speed measurement is temporarily required.

[0018] 3. The mobile device and the cleaning device are provided to provide power to the scraping device for convenient cleaning of the camera screen. The rainwater pipe is provided to connect to the water tank to collect rainwater for cleaning the camera screen, so that it can be cleaned more thoroughly.

[0019] 4. By setting a stepper motor and a dustproof door to close quickly when a vehicle passes by, dust pollution can be reduced. When a vehicle passes by, the dustproof door moves down and the water blocking device is set to block the middle of the rainwater pipe to prevent rainwater from continuing to flow into the blurry camera. At the same time, the limit plate is pressed down to pull the scraper device to the highest point to prevent the camera from being covered, which is more energy-saving.
