Description

Technical Field

[0001] This invention belongs to the field of lidar technology and relates to a high-speed airflow telescopic dustproof air outlet component for a lidar fixed device. Background Technology

[0002] LiDAR (Light Detection and Ranging) is a radar system that uses laser beams to detect the position, velocity, and other characteristics of targets. When installing an intelligent system independent of the main system on port machinery, a LiDAR detection device needs to be installed on the ship loader equipment. This allows the port machinery to identify the situation on-site using LiDAR, providing decision-making support for the intelligent system. During operation, LiDAR must be exposed to the outside without obstructions to function properly. Therefore, it is easily contaminated by dust, mud, and other pollutants in the air. These contaminants can obstruct the LiDAR, causing discrepancies between the road information collected by the LiDAR and the actual road conditions, thus affecting the safety and performance of various detection applications. Therefore, a cleaning component is needed to clean the LiDAR.

[0003] A traffic condition display device disclosed in Chinese Patent CN115595911A includes a base, a mounting frame on the base, a controller, a camera, a display screen and a communication gateway on the mounting frame, a transparent cover for covering the display screen on the mounting frame, and a drive mechanism on the mounting frame. The drive mechanism is connected to a scraper and can drive the scraper to move along the surface of the transparent cover.

[0004] The device cleans the transparent cover using a scraper, but after a long period of cleaning, impurities or dust accumulate on the scraper, requiring it to be disassembled for cleaning, making it inconvenient to use.

[0005] To address the aforementioned problems, this invention proposes a high-speed airflow telescopic dustproof air outlet component for a fixed lidar device. Summary of the Invention

[0008] Several air outlet pipes are fixedly installed on the protective frame. The air outlet pipes are evenly distributed outside the lidar. A second nozzle is slidably installed at the end of each air outlet pipe. An air outlet hole is opened on the side of each second nozzle facing the lidar.

[0009] Furthermore, the water outlet pipe includes a first connecting pipe, one end of which is fixedly connected to a water pump. A water tank is fixedly connected inside the protective frame, and each water pump is fixedly connected to one side of the water tank. The input pipes of the water pumps extend into the water tank, and the first spray pipe is slidably disposed inside the first connecting pipe.

[0010] Furthermore, a first sliding tube is fixedly connected to one end of each first nozzle, and a first sliding groove is provided on the inner wall of each first connecting tube, with the first sliding tube slidably connected to the interior of the corresponding first sliding groove;

[0011] A first spring is fixedly connected to one end of the first sliding tube near the first nozzle. The first spring is sleeved on the corresponding first nozzle, and the other end of the first spring is fixedly connected to the end face of the corresponding first sliding groove.

[0012] Furthermore, a base is fixedly connected to the bottom surface of the inner cavity of the protective frame, the top surface of the base is arc-shaped, the laser radar is rotatably mounted on the top surface of the base, one end of the laser radar is rotatably connected to the water tank, and a toothed ring is fixedly sleeved on the laser radar.

[0013] A second motor is fixedly connected to the bottom surface inside the protective frame, and a gear is fixedly connected to the output shaft of the second motor, with the gear meshing with a gear ring.

[0014] Furthermore, the air outlet pipe includes a second connecting pipe, which is L-shaped. One end of each second connecting pipe is fixedly connected to the inner wall of the protective frame, and the other end of each second connecting pipe is parallel to the first connecting pipe. The second nozzle is slidably disposed inside the second connecting pipe.

[0015] Furthermore, a second sliding tube is fixedly connected to one end of each second nozzle, and a second sliding groove is provided on the inner wall of each second connecting tube, with the second sliding tube slidably connected to the interior of the corresponding second sliding groove;

[0016] A second spring is fixedly connected to one end of the second sliding tube near the second nozzle. The second spring is sleeved on the corresponding second nozzle, and the other end of the second spring is fixedly connected to the end face of the corresponding second sliding groove.

[0017] Furthermore, each of the protective frames and the second connecting pipes has a through hole at the connection point, and the through hole is connected to the corresponding second connecting pipe. A fan is fixedly installed inside each through hole, a heating plate is fixedly connected inside the end of each second connecting pipe near the fan, and a filter screen is fixedly installed inside the end of each through hole away from the second connecting pipe.

[0018] Furthermore, each second nozzle is rotatably connected by several connecting shafts, and each connecting shaft is fixedly fitted with a swing plate, with the ends of two adjacent swing plates slidingly engaged.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The high-speed airflow telescopic dustproof air outlet component of this lidar fixed device is equipped with a first nozzle and a second nozzle. In use, the water pump is started, and water in the water tank enters the first sliding tube through the first connecting pipe. The water is then sprayed onto the lidar through the water outlet on the first nozzle to rinse the lidar. After rinsing, the fan is started to bring air into the second sliding tube. The air is then blown onto the lidar through the second nozzle to dry the lidar. The rinsed water is directly carried away, reducing the workload of the staff and making it more convenient to use.

[0023] 2. When the high-speed airflow telescopic dustproof air outlet component of the lidar fixing device sprays water using the first nozzle, the water impacts the first nozzle, causing it to slide outwards towards the first connecting pipe. This causes the first sliding tube to slide inside the first connecting pipe and compress the first spring, facilitating the first nozzle's rinsing of the lidar. After rinsing, the first spring pushes the first sliding tube, moving the first nozzle into the first connecting pipe. Similarly, after spraying air, the second nozzle enters the second connecting pipe, sealing the air outlet and water outlet to reduce clogging by impurities. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1-8 As shown, the technical solution adopted by the present invention is as follows: A high-speed airflow telescopic dustproof air outlet component for a fixed lidar device includes a protective frame 1, and a lidar 5 is rotatably mounted inside the protective frame 1. The lidar 5 is an advanced radar system that uses a laser beam for detection and ranging. It uses a laser as the emission light source, and obtains the target's position, velocity, and other characteristic information by emitting a laser beam and receiving the signal reflected back from the target. A transmitter 6 is provided at one end of the lidar 5.

[0035] A mounting base 2 is fixedly connected to the bottom of the protective frame 1 for securing the lidar 5. A protective plate 3 is fixedly connected to one side of the top of the protective frame 1, providing protection for the top of the lidar 5. A camera 7 is fixedly connected to the bottom surface of the inner cavity of the protective frame 1, with the lens of the camera 7 facing the transmitter 6. This allows the camera 7 to monitor the surface of the transmitter 6 and the lidar 5 for dust or impurities, facilitating timely cleaning.

[0036] The protective frame 1 has several water outlet pipes evenly distributed around the outside of the lidar 5. Each water outlet pipe has a first nozzle 12 slidably mounted at its end, and each first nozzle 12 has a water outlet hole on one side facing the lidar 5. This allows water from each first nozzle 12 to be sprayed onto the lidar 5 through the water outlet hole, thus rinsing the lidar 5 and the transmitting end 6.

[0037] The water outlet pipe includes a first connecting pipe 10, and a water pump 9 is fixedly connected to one end of each first connecting pipe 10. A water tank 8 is fixedly connected inside the protective frame 1, and each water pump 9 is fixedly connected to one side of the water tank 8. The input pipe of each water pump 9 extends into the water tank 8. The water pump 9 is started, allowing water from the water tank 8 to enter the first connecting pipe 10. The first spray pipe 12 is slidably disposed within the first connecting pipe 10.

[0038] Each first nozzle 12 is fixedly connected to a first sliding tube 11 at one end, and a first groove is formed on the inner wall of each first connecting tube 10. The first sliding tube 11 is slidably connected to the inside of the corresponding first groove. By sliding the first sliding tube 11 inside the first groove, one end of the first nozzle 12 is positioned inside the first connecting tube 10.

[0039] A first spring 13 is fixedly connected to one end of the first sliding tube 11 near the first nozzle 12, and the first spring 13 is sleeved on the corresponding first nozzle 12. The other end of the first spring 13 is fixedly connected to the end face of the corresponding first sliding groove. In the initial state, the first spring 13 will push the first sliding tube 11 to one end of the first sliding groove, so that one end of the first sliding tube 11 abuts against the end face of the first sliding groove, and the first nozzle 12 is completely located inside the first connecting tube 10.

[0040] A base 4 is fixedly connected to the bottom surface of the inner cavity of the protective frame 1. The top surface of the base 4 is arc-shaped, and the lidar 5 is rotatably mounted on the top surface of the base 4. One end of the lidar 5 is rotatably connected to the water tank 8. The lidar 5 is positioned on the base 4. A toothed ring 22 is fixedly fitted on the lidar 5.

[0041] A second motor 23 is fixedly connected to the bottom surface inside the protective frame 1. A gear 24 is fixedly connected to the output shaft of the second motor 23, and the gear 24 meshes with the gear ring 22. The second motor 23 drives the gear 24 to rotate, the gear 24 drives the gear ring 22 to rotate, and thus the lidar 5 rotates.

[0042] Several air outlet pipes are fixedly installed on the protective frame 1, and these air outlet pipes are evenly distributed on the outside of the lidar 5. A second nozzle 16 is slidably installed at the end of each air outlet pipe, and each second nozzle 16 has an air outlet on its side facing the lidar 5. This allows the air in each second nozzle 16 to be blown onto the lidar 5 through the air outlet, thereby drying the lidar 5 after rinsing.

[0043] The air outlet duct includes a second connecting pipe 14, which is L-shaped. One end of each second connecting pipe 14 is fixedly connected to the inner wall of the protective frame 1, and the other end of each second connecting pipe 14 is parallel to the first connecting pipe 10. A second nozzle 16 is slidably disposed within the second connecting pipe 14. The sliding direction of the second nozzle 16 is the same as that of the first nozzle 12.

[0044] Each second nozzle 16 has a second sliding tube 15 fixedly connected to one end. Each second connecting tube 14 has a second groove on its inner wall, and the second sliding tube 15 is slidably connected to the inside of the corresponding second groove. By sliding the second sliding tube 15 inside the second groove, one end of the second nozzle 16 is positioned inside the second connecting tube 14.

[0045] A second spring 17 is fixedly connected to one end of the second sliding tube 15 near the second nozzle 16, and the second spring 17 is sleeved on the corresponding second nozzle 16. The other end of the second spring 17 is fixedly connected to the end face of the corresponding second slide groove. In the initial state, the second spring 17 will push the second sliding tube 15 to one end of the second slide groove, so that one end of the second sliding tube 15 abuts against the end face of the second slide groove, and the second nozzle 16 is completely located inside the second connecting tube 14.

[0046] Each protective frame 1 has a through hole at its connection with each of the second connecting pipes 14, and the through hole communicates with the corresponding second connecting pipe 14. A fan is fixedly installed inside each through hole to blow air into the second connecting pipe 14. A heating plate 25 is fixedly connected to the end of each second connecting pipe 14 closest to the fan, heating the air blown into the second connecting pipe 14. A filter screen is fixedly installed inside the end of each through hole furthest from the second connecting pipe 14 to filter the air entering the through hole, reducing the possibility of impurities clogging the second nozzle 16.

[0047] The heating plate 25 works primarily by converting electrical energy into heat energy, representing a form of electrical energy utilization. When current passes through the internal resistor or heating alloy wire of the heating plate 25, electrical energy is converted into heat energy. The heating alloy wire heats up and transfers the heat to the surface of the heating plate 25 through conduction and radiation, thereby raising the surface temperature and achieving the heating purpose. The heating plate 25 is an existing product.

[0048] Each second nozzle 16 has several connecting shafts that rotate at intervals, and each connecting shaft is fixedly fitted with a swing plate 19. The ends of two adjacent swing plates 19 are slidably engaged, allowing each swing plate 19 to rotate.

[0049] Each second nozzle 16 is fixedly connected to one side with a first motor 18, which drives the outermost connecting shaft to rotate. Each second nozzle 16 is equipped with a transmission assembly, which cooperates with the first motor 18. When the first motor 18 drives the outermost connecting shaft to rotate, the transmission assembly drives the remaining connecting shafts to rotate synchronously. Through the first motor 18 and the transmission assembly, all connecting shafts within the second nozzle 16 rotate synchronously.

[0050] The transmission assembly includes a first connecting rod 20 and a second connecting rod 21. A first connecting rod 20 is fixedly sleeved on each connecting shaft, and a second connecting rod 21 is hinged between two adjacent first connecting rods 20. The first connecting rod 20 is rotated through the transmission of the second connecting rod 21.

[0051] Working principle:

[0052] When in use, the mounting base 2 is fixed in a suitable position with a wide field of vision and no obstructions by bolts so that the lidar 5 can work.

[0053] If, during the operation of the lidar 5, the camera 7 detects impurities on the transmitter 6 and lidar 5, the lidar 5 and transmitter 6 need to be cleaned.

[0054] Start water pump 9 and second motor 23.

[0055] The water pump 9 will pump the water in the water tank 8 into the first connecting pipe 10, and the water in the first connecting pipe 10 will enter the first sliding pipe 11 and the first spray pipe 12.

[0056] As the water level in the first connecting pipe 10 increases, the water impacts the first nozzle 12, causing the first nozzle 12 to move outward from the first connecting pipe 10. This causes the first sliding pipe 11 to slide inside the first sliding groove and compress the first spring 13.

[0057] The first nozzle 12 will drive the water outlet to move outward of the first connecting pipe 10, so that water can be flushed through the water outlet to wash the lidar 5 and the transmitter 6.

[0058] The second motor 23 drives the gear 24 to rotate, which in turn drives the gear ring 22 to rotate, causing the lidar 5 to rotate. This facilitates water rinsing of different parts of the lidar 5, making the rinsing more thorough.

[0059] After rinsing is complete, turn off the water pump 9 to stop spraying water. The first spring 13 will push the first sliding tube 11 to slide inside the first sliding groove, causing the first nozzle 12 to move into the first connecting tube 10.

[0060] Start the fan to power the heating plate 25, and the temperature of the heating plate 25 will rise.

[0061] Air is introduced into the second connecting pipe 14, and the heating plate 25 heats the air into hot air. The hot air then enters the interior of the second sliding pipe 15 and the second nozzle 16. The air impacts the second nozzle 16, causing it to move outward from the second connecting pipe 14, which in turn causes the second sliding pipe 15 to slide inside the second groove and compress the second spring 17.

[0062] The second nozzle 16 will cause the air outlet to move outwards from the second connecting pipe 14, so that air is blown through the air outlet towards the lidar 5 and the transmitter 6. This dries the lidar 5 and the transmitter 6.

[0063] At the same time, the second motor 23 will drive the lidar 5 to rotate, making the drying effect better.

[0064] During the drying process, the first motor 18 can be activated, causing a connecting shaft connected to it to rotate. The first connecting rod 20 at the end of the connecting shaft rotates, and the other end of the first connecting rod 20 drives one end of the second connecting rod 21 connected to it to rotate. The other end of the second connecting rod 21 then drives the next first connecting rod 20 to rotate. This process continues, causing all the first connecting rods 20 to rotate, which in turn causes all the connecting shafts to rotate, and all the swing plates 19 to rotate. This changes the tilt angle of the swing plates 19, thereby changing the angle of the air outlet of the second nozzle 16 and further improving the drying effect.

[0065] After air drying is complete, turn off the fan to stop blowing air. The second spring 17 will push the second sliding tube 15 to slide inside the second slide groove, causing the second nozzle 16 to move into the second connecting tube 14. This serves to prevent dust from entering the second nozzle 16.

[0066] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
