[0002] Expressways are high-grade highways. Although different countries have different names for expressways, they all refer to highways with more than four lanes, separated traffic in two directions, fully controlled entrances and exits, and all grade separations. In addition, many countries also call direct trunk roads with partially controlled entrances and exits and not all grade separations expressways. Currently, vehicle speeds are measured on expressways through radar speed measuring devices, which display the real-time speed of the vehicle and facilitate warnings to moving vehicles.

When the scraper moves downward and separates from the inner wall of the camera, the sealing plate will pop up upward under the action of spring one. When the scraper moves upward, the scraper will scrape the remaining water stains to the top of the scraper. At this time, the raised sealing plate will block the scraped water to make it gather. As the scraper drives the sealing plate to move upward, the sealing plate will first contact the inner wall of the camera. At this time, a closed space will be formed between the sealing plate, the scraper and the camera. The space is filled with air or water, and as the scraper continues to move upward, the air or water in the enclosed space will push the sealing rod upward and compress spring 2. When the sealing rod moves to its bottom and separates from the inner wall of the camera, the water or air in the enclosed space will enter the interior of the camera and can be discharged from both sides of the camera. This design allows the scraper to discharge the scraped water when it moves upward or downward, thereby improving the cleaning efficiency. At the same time, it can prevent the scraped water from being squeezed and splashed between the shield and the scraper after the scraper moves upward to the final position, causing the water to enter the interior of the scraper from the air jet of the scraper and be unable to be discharged, or to flow back to the mirror surface of the camera from the gap between the shield and the scraper, thereby affecting the camera's line of sight.

This design can accelerate the drying of water marks on the camera mirror surface through the air ejected from the scraper jet holes, keep the mirror surface clean, and ensure that the quality of the image taken by the camera is not affected.

[0011] Preferably, the top of spring three is fixedly connected to the inner wall of the camera, the back of sliding rod one is fixedly connected to spring four, the back of spring four is fixedly connected to the inner wall of the camera, the front of sliding rod one is fixedly connected to a baffle, and the bottom of the baffle contacts the lower baffle. When the scraper moves upward until its top contacts the lifting plate, as the scraper continues to move upward, the lifting plate will be pushed upward by the scraper and compress spring three. Spring three will squeeze the air inside the camera during the movement, and the squeezed air will push sliding rod one toward the back. When the scraper moves to the final position, sliding rod one will also drive the baffle to move to the final position, and the baffle will drive the lower baffle to move as a whole. The baffle will block most of the scraper, and the lower baffle will block the lower side of the scraper.

[0012] Preferably, a sliding rod 2 is fixedly connected to the top of the lower shield plate, the outer surface of the sliding rod 2 is slidably connected to the inner wall of the shield plate, a spring 5 is sleeved on the outer surface of the sliding rod 2, the top of the spring 5 is fixedly connected to the outer wall of the sliding rod 2, and the bottom of the spring 5 is fixedly connected to the inner wall of the shield plate.

When the scraper moves downward to a certain position, the shield plate as a whole will be separated from the scraper under the action of spring 4, and the scraper can move downward smoothly. This design can shield the scraper through the shield plate and the lower shield plate to prevent dew from being directly generated inside the scraper through the air jet holes and unable to be discharged, or dew generated on the top of the scraper from falling into the inside of the scraper through the air jet holes on the top of the scraper.

[0013] A method for using a highway radar early warning speed measuring device comprises the following steps:

[0014] S1: When using this device, first install the device to the designated position. When it is necessary to clean the dew on the camera mirror, start the motor to drive the scraper to move up and down to scrape the dew on the camera;

[0015] S2: When the scraper moves downward and separates from the inner wall of the camera, the sealing plate will pop up under the action of spring 1 to block the scraped water. As the scraper drives the sealing plate to move upward, the blocked water will be discharged. When the connecting rod moves downward, the air jet hole will spray air to accelerate the air flow.

[0016] S3: When the scraper moves upward until its top contacts the lifting plate, as the scraper continues to move upward, the lifting plate squeezes the air inside the camera, driving the shield to move toward the back as a whole, thereby shielding the scraper.

[0017] The present invention has the following beneficial effects:

[0018] 1. When it is necessary to clean the dew on the camera mirror surface, the present invention starts the motor to drive the cam to rotate. As the cam rotates and due to the limiting effect of the camera on the hollow rod, the cam will drive the connecting rod to move back and forth up and down through the rotating rod, and the connecting rod will drive the scraper to move back and forth up and down on the camera mirror surface through the hollow rod, and then the dew on the camera mirror surface will be scraped off by the scraper. This design can scrape off the dew on the camera by the scraper, preventing the dew from blocking the camera, interfering with the camera's line of sight, and affecting its normal shooting of the vehicle.

[0019] 2. In the process of the scraper of the present invention moving downward and separating from the inner wall of the camera, the sealing plate will pop up upward under the action of the spring 1. In the process of the scraper moving upward, the scraper will scrape the remaining water stains to the top of the scraper. At this time, the raised sealing plate will block the scraped water to make it gather. As the scraper drives the sealing plate to move upward, the sealing plate will first contact the inner wall of the camera. At this time, a closed space will be formed between the sealing plate, the scraper and the camera. As the scraper continues to move upward, the air or water in the closed space will push the sealing rod upward and press Second, when the sealing rod moves to its bottom and separates from the inner wall of the camera, water or air in the enclosed space will enter the interior of the camera and can be discharged from both sides of the camera. This design allows the scraper to move up and down to discharge the scraped water, thereby improving cleaning efficiency. At the same time, it can prevent the scraper from squeezing and splashing the scraped water between the baffle and the scraper after moving upward to the final position, causing the water to enter the interior of the scraper from the air jet of the scraper and be unable to be discharged, or to flow back to the mirror surface of the camera from the gap between the baffle and the scraper, affecting the camera's line of sight.

[0020] The air in the air filter presses on the upper and lower surfaces of the air intake pipe, and the outside air is sucked into the air intake pipe through the one-way valve. The compressed air enters the connecting pipe through the one-way valve, and the connecting pipe passes the air into the air guide hose, and the air guide hose passes the air into the interior of the hollow rod, and the hollow rod passes the air into the air guide cavity. The air passed into the air guide cavity will be ejected from the air jet holes opened above the scraper, and the ejected air will hit the mirror surface of the camera to accelerate the air flow. When the connecting rod drives the pressure rod to move upward through the fixed rod, the pressure rod will push the air into the scraper and discharge it in the same way as the above process. This design can accelerate the drying of water marks on the mirror surface of the camera through the air ejected from the scraper jet hole, keep the mirror surface clean, and ensure that the quality of the image taken by the camera is not affected.

[0021] 4. When the scraper moves upward to its top and contacts with the lifting plate, as the scraper continues to move upward, the lifting plate will be pushed upward by the scraper and compress the spring three. The spring three will squeeze the air inside the camera during the movement, and the squeezed air will push the sliding rod one toward the back. When the scraper moves to the final position, the sliding rod one will also drive the shield plate to move to the final position, and the shield plate will drive the lower shield plate to move as a whole. The shield plate will block most of the position of the scraper, and the lower shield plate will block the lower side of the scraper. When the scraper needs to move downward, the scraper will push the lower shield plate downward and stretch the spring five to give the scraper space to move downward. When the scraper moves downward to a certain position, the shield plate as a whole will be separated from the scraper under the action of the spring four, and the scraper can move downward smoothly. This design can block the scraper through the shield plate and the lower shield plate to prevent dew from being directly generated inside the scraper through the air jet hole and unable to be discharged, or dew generated on the top of the scraper will fall into the inside of the scraper through the air jet hole at the top of the scraper.

When the scraper 109 moves upward, the scraper 109 will scrape the remaining water stains to the top of the scraper 109. At this time, the raised sealing plate 202 will block the scraped water to make it gather. As the scraper 109 drives the sealing plate 202 to move upward, the sealing plate 202 will first contact the inner wall of the camera 103. At this time, a closed space will be formed between the sealing plate 202, the scraper 109 and the camera 103. As the scraper 109 continues to move upward, the air or water in the closed space will push the sealing rod 203 upward and press The second compression spring 204, when the sealing rod 203 moves to its bottom and separates from the inner wall of the camera 103, the water or air in the enclosed space will enter the interior of the camera 103 and can be discharged from both sides of the camera 103. This design allows the scraper 109 to discharge the scraped water when it moves upward and downward, thereby improving the cleaning efficiency. At the same time, it can prevent the scraper 109 from squeezing and splashing the scraped water between the shield 305 and the scraper 109 after it moves upward to the final position, causing the water flow to enter the interior of the scraper 109 from the air jet of the scraper 109 and cannot be discharged, or to flow back to the mirror surface of the camera 103 from the gap between the shield 305 and the scraper 109, thereby affecting the line of sight of the camera 103;

[0053] When the connecting rod 107 moves downward, it will drive the pressing rod 207 to move together through the fixing rod 206. When the pressing rod 207 moves, it will squeeze the air in the air storage cylinder 208 and inhale the external air into the upper part of the pressing rod 207 inside the air storage cylinder 208 through the air outlet one-way valve 210. The squeezed air will enter the connecting pipe 211 through the air outlet one-way valve 210. The connecting pipe 211 will pass the air into the air guide hose 212. The air guide hose 212 will pass the air into the interior of the hollow rod 108. The hollow rod 108 will suck the air The air passing into the air guide cavity 213 will be ejected from the air jet holes opened on the upper and lower sides of the scraper 109, and the ejected air will hit the mirror surface of the camera 103 to accelerate the air flow. When the connecting rod 107 drives the pressure rod 207 to move upward through the fixed rod 206, the pressure rod 207 will push the air into the scraper 109 and discharge it in the same way as the above process. This design can accelerate the drying of water marks on the mirror surface of the camera 103 through the air jet holes of the scraper 109, keep the mirror surface clean, and ensure that the quality of the image taken by the camera is not affected;

[0054] When the scraper 109 moves upward to its top and contacts the lifting plate 301, as the scraper 109 continues to move upward, the lifting plate 301 will be pushed upward by the scraper 109 and compress the spring three 302. The spring three 302 will squeeze the air inside the camera 103 during the movement, and the squeezed air will push the sliding rod 1 303 to the back. When the scraper 109 moves to the final position, the sliding rod 1 303 will also drive the shield 305 to move to the final position. The shield 305 will drive the lower shield 306 to move as a whole. The shield 305 will block most of the position of the scraper 109, and the lower shield 306 will move the lower side of the scraper 109. When the scraper 109 needs to move downward, the scraper 109 will push the lower shield 306 downward and stretch the spring five 308 to give the scraper 109 space to move downward. When the scraper 109 moves downward to a certain position, the shield 305 will be separated from the scraper 109 as a whole under the action of the spring four 304. At this time, the scraper 109 can move downward smoothly. This design can shield the scraper 109 through the shield 305 and the lower shield 306 to prevent dew from being directly generated inside the scraper 109 through the air jet holes and unable to be discharged, or the dew generated on the top of the scraper 109 will fall into the inside of the scraper 109 through the air jet holes at the top of the scraper 109.
