Description

Technical Field

[0001] The utility model relates to the technical field of radar maintenance equipment, and more specifically, to a laser radar cleaning and protection device. Background Art

[0002] LiDAR uses a laser beam as a detection signal. By measuring parameters such as the time difference between emission and reception and the reflection intensity, it can determine the distance, speed, and shape of a target object. Currently, LiDAR is widely used, such as at construction sites and on vehicles.

[0003] Dirt on the surface of the lidar will have a significant impact on its performance. This is because the lidar perceives the surrounding environment by emitting laser beams and receiving their reflections. If there is dirt on the radar surface, such as dust, dirt or water droplets, these substances may scatter or absorb the laser beam, causing the radar to be unable to accurately receive the reflected signal, thereby affecting its perception ability. Specifically, it will cause the radar's perception of the surrounding environment to become blurred or inaccurate, reducing the accuracy of measurement and positioning. Dirt may also cause damage or failure of the optical components inside the lidar, further affecting its working stability and reliability. Currently, the cleaning and maintenance of lidars are all done manually with detergents or solvents such as alcohol to wipe the radar surface. However, the cleaning interval of radars used in harsh environments is short, which puts great pressure on manual labor and requires auxiliary tools for effective cleaning.

[0004] In summary, how to solve the current problem that laser radar is inconvenient to clean and has no effective dust prevention measures is an urgent problem that needs to be solved by technical personnel in this field. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The core of this utility model is to provide a laser radar cleaning device that can be quickly and efficiently used.

[0036] Please refer to Figures 1-6 A laser radar cleaning and protection device includes a mounting frame 1, a cleaning component 4 and a protection component 3. The mounting frame 1 is used to fix the laser radar 5 and install it in the use position. A protective cover 2 is provided on the outside of the laser radar 5 for protection. The cleaning component 4 includes several nozzles 401 installed on the mounting frame 1 and a water pump 402 connected to the nozzle 401, which is used to spray high-pressure water columns on the laser radar 5 to achieve a cleaning effect. The protection component 3 includes a fan 301 for blowing air on the surface of the laser radar 5 to achieve a cleaning or protection effect by blowing air.

[0037] It should be noted that the material of the protective cover 2 in the embodiment of the present invention is not specifically limited. In some embodiments, glass, plastic, etc. can be used.

[0038] In addition, the installation in the embodiment of the present invention can adopt a telescopic rod structure with a lifting function. Specifically, a multi-section telescopic rod is adopted. The telescopic function facilitates rapid adjustment of the installation height of the laser radar 5, which is conducive to adapting to different usage environments.

[0039] In addition, the embodiment of the present invention does not limit the specific number and installation position of the nozzles 401. The nozzles 401 can be of any number as long as they can effectively flush the protective cover 2.

[0040] In addition, the nozzle 401 of the embodiment of the present invention can adopt a high-pressure nozzle 401, and the fan 301 can adopt a high-pressure fan 301, so as to increase the cleaning effect and the protective effect of the protective cover 2 through the effect of high pressure.

[0041] During use, the mounting frame 1 is installed in the desired position, and the laser radar 5 is installed on the mounting frame 1, and the cleaning component 4 and the protective component 3 are both installed on the mounting frame 1. A protective cover 2 for protection is provided on the outside of the laser radar 5 to protect the laser radar 5. The protective cover 2 is made of transparent material. When cleaning, only the protective cover 2 needs to be cleaned to avoid damage to the laser radar 5. The cleaning component 4 includes several nozzles 401 and a water pump 402 installed on the mounting frame 1, which are used to spray high-pressure water columns on the laser radar 5 to achieve a cleaning effect. That is to say, the nozzle 401 is directly installed on the mounting frame 1. When cleaning is required, only the water pump 402 needs to be turned on to flush the protective cover 2, avoiding the need for manual wiping or flushing, reducing manual labor intensity, and avoiding safety hazards during cleaning. The protective component 3 includes a fan 301, which is used to blow air to the surface of the laser radar 5. The blowing effect of the fan 301 can reduce the dust adhering to the protective cover 2, thereby reducing the pressure and number of cleanings.

[0042] Please refer to Figure 4-Figure 6 In some embodiments, a mounting base 101 is installed on the mounting frame 1, the laser radar 5 is installed on the mounting base 101, the cleaning component 4 also includes a cleaning control cabinet 403, and the water pump 402 is installed in the cleaning control cabinet 403. The control cabinet is provided with buttons and a control panel for controlling the water pump 402. The working time of the water pump 402 is controlled by a control program. That is to say, the water pump 402 only needs to be started during cleaning, and the water pump 402 can stop automatically. Several nozzles 401 are installed on the mounting base 101, and the nozzles 401 are connected to the water pump 402 through pipes, and a water supply is provided inside the cleaning control cabinet 403. The water supply can be a container for cleaning liquid.

[0043] It should be noted that in the embodiment of the present invention, the water pump 402 can also be directly connected to the tap water pipe or the well, and a detergent addition port is provided at the water inlet of the water pump 402 to facilitate the user to add detergent to the cleaning liquid and improve the cleaning effect.

[0044] Please refer to Figure 4-Figure 6 In order to further improve the cleaning effect of the protective cover 2, in some embodiments, the number of the plurality of nozzles 401 is at least four, and they are evenly distributed around the laser radar 5. That is to say, the protective cover 2 is surrounded by four nozzles 401, which increases the area and intensity of cleaning the protective cover 2, thereby improving the cleaning effect of the protective cover 2.

[0045] It should be noted that in the embodiment of the present invention, a single or dual nozzle 401 can be used. By adjusting the position of nozzle 401, when a single nozzle 401 is used, nozzle 401 is positioned directly toward protective cover 2. By adding an electric cylinder structure to drive nozzle 401, the electric cylinder drives nozzle 401 toward protective cover 2 during cleaning. After cleaning, the electric cylinder drives nozzle 401 to return to its original position, thereby avoiding interference with the operation of laser radar 5. When two nozzles 401 are used, they are arranged in a V-shaped structure to increase the cleaning area and strength of protective cover 2.

[0046] Please refer to Figure 4-Figure 6 In order to further improve the protective effect of the protective cover 2, in some embodiments, the protective assembly 3 further includes a fan control cabinet 302 and a wind cover 303. The fan 301 is installed in the fan control cabinet 302. The wind cover 303 is sealed with the mounting base 101 and communicates with the fan 301 through a pipeline. The wind cover 303 is provided with an air outlet 304. The laser radar 5 is located inside the wind cover 303 and passes through the wind cover 303 through the air outlet 304. A gap is left between the laser radar 5 and the wind cover 303. In other words, By setting an air outlet 304 on the wind hood 303, the protective hood 2 is passed through the air outlet 304, and a certain gap is left between the protective hood 2 and the wind hood 303. At this time, the fan 301 provides high-pressure wind to the wind hood 303, prompting the wind to be ejected from the gap between the protective hood 2 and the wind hood 303, thereby forming a protective high-pressure wind wall for the protective hood 2, reducing dust falling onto the protective hood 2 during use, especially when used in a construction environment, avoiding the solution from falling onto the protective hood 2, and greatly extending the cleaning interval of the protective hood 2.

[0047] It should be noted that the protective cover 2 in the embodiment of the present invention is hollow, and the shape of the air outlet 304 on the protective cover 2 can be designed to be a contoured shape according to the protective cover 2 .

[0048] In addition, in the embodiment of the present invention, the pressure of the high-pressure wind wall can be increased by reducing the gap between the protective cover 2 and the wind cover 303, thereby improving the protective effect of the protective cover 2.

[0049] In order to further improve the uniformity of the high-pressure wind wall after formation, in some embodiments, the connection between the fan 301 and the wind cover 303 is located on the side of the wind cover 303 close to the mounting seat 101, and is located at the center of the wind cover 303. That is to say, by setting the pipe connection of the fan 301 at the center of the wind cover 303, the instability of the high-pressure wind wall caused by position deviation is reduced, which is beneficial to improving the protection effect of the protective cover 2.

[0050] It should be noted that, in the embodiment of the present invention, the center position of the air cover 303 is a position corresponding to the air outlet 304 , that is, the air outlet 304 coincides with the center position in projection.

[0051] In addition, in the embodiment of the present invention, the pipe connection position can also be set at other positions to ensure the uniformity of the generated high-pressure wind wall by increasing the pressure of the fan 301.

[0052] In order to further enhance the protective effect of the protective cover 2 and reduce the situation where dust or solution falls on the protective cover 2, in some embodiments, the air outlet 304 is provided with a bent edge facing the laser radar 5, that is, the wind wall is guided by the bent edge so that the wind wall converges above the protective cover 2, thereby achieving complete protection of the protective cover 2, which is conducive to further reducing the cleaning interval of the protective cover 2.

[0053] It should be noted that the bent edge in the embodiment of the present invention can be in a chamfered shape or an arc shape.

[0054] In order to further improve the cleaning effect of the protective cover 2, in some embodiments, a swivel is rotatably installed on the mounting base 101, and several nozzles 401 are installed on the swivel. A driving member for controlling the rotation of the swivel is installed on the mounting base 101. That is to say, the swivel can be used to rotate several nozzles 401 around the protective cover 2, thereby increasing the cleaning area of ​​the protective cover 2, effectively realizing the cleaning of the protective cover 2 without dead angles, and greatly improving the cleaning effect. At the same time, the driving member drives the swivel to rotate back and forth, which can avoid the entanglement of the pipes connected to the several nozzles 401.

[0055] It should be noted that the embodiments of the present invention do not limit the specific structure of the rotary drive member. In some embodiments, the rotary drive member is a motor, such as a DC brushed motor or a stepper motor.

[0056] In order to further improve the cleaning effect of the protective cover 2, in some embodiments, several nozzles 401 are provided with cleaning parts. The cleaning parts can contact the protective cover 2 when the nozzle 401 sprays high-pressure water. The cleaning parts are made of nylon material and are tubular. That is to say, a cleaning part made of soft material is arranged at the position where the nozzle 401 sprays water. The water flow will cause the cleaning part to swing and contact with the protective cover 2, so that the cleaning part can wipe the protective cover 2, which is beneficial to further improve the cleaning effect of the protective cover 2 and can effectively clean stubborn stains on the protective cover 2.

[0057] That is to say, the focus of the embodiment of the present invention is: using the above-mentioned cleaning component 4 and protective component 3, both the cleaning component 4 and the protective component 3 are installed on the mounting frame 1, and a protective cover 2 for protection is provided on the outside of the laser radar 5 to protect the laser radar 5. The protective cover 2 is made of transparent material. When cleaning, only the protective cover 2 needs to be cleaned, thereby avoiding damage to the laser radar 5. The cleaning component 4 includes several nozzles 401 and a water pump 402 installed on the mounting frame 1, which are used to spray high-pressure water columns on the laser radar 5 to achieve a cleaning effect. That is to say, the nozzle 401 is directly installed on the mounting frame 1. When cleaning is required, only the water pump 402 needs to be turned on to flush the protective cover 2, thereby avoiding the need for manual wiping or flushing, reducing manual labor intensity, and avoiding safety hazards during cleaning. The protective component 3 includes a fan 301, which is used to blow air to the surface of the laser radar 5. The blowing effect of the fan 301 can reduce the dust adhering to the protective cover 2, thereby reducing the pressure and number of cleanings.

[0058] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
