Description

Technical Field

[0001] The utility model relates to the technical field of inspection robots, and in particular to a smart park inspection robot. Background Art

[0002] With the popularization of intelligence and informatization, park management has also shifted from traditional manual patrols to intelligent inspections. In order to improve park safety, improve inspection efficiency and reduce the workload of inspectors, more and more companies have begun to use security inspection robots to inspect the park.

[0003] The inspection robot uses advanced sensor technology and artificial intelligence algorithms, and can perform real-time environmental detection, image analysis, face recognition, intelligent navigation, voice recognition and other functions. During the inspection process, it can timely grasp the safety status of the park. Due to the back and forth walking of staff inside the smart park, the air flow rate around the soles of the staff increases, causing the dust on the soles to float in the air. When the staff passes by the inspection robot, the dust in the air is easily attached to the lens of the inspection machine under the action of static electricity. If the dust is not cleaned in time, the clarity of the camera will be greatly reduced, which will affect the normal operation of the inspection robot.

[0004] At present, the lens part of the inspection robot is equipped with a reciprocating cleaning plate. When a large amount of dust adheres to the lens part, the cleaning plate is started to swing back and forth to scrape off the dust attached to the lens part. However, since the dust is composed of fine particles and has high strength, when the scraper cleans the lens, the dust will adhere to the cleaning end of the scraper. As the scraper swings back and forth, it is easy to cause friction between the dust particles and the outer wall of the lens, causing the lens to be scratched, reducing the clarity of the lens and affecting the normal operation of the inspection robot. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a smart park inspection robot, which aims to improve the problem in the existing technology that dust is composed of fine particles and has high strength. When the scraper cleans the lens, the dust will adhere to the cleaning end of the scraper. As the scraper swings back and forth, it is easy to cause friction between the dust particles and the outer wall of the lens, causing the lens to be scratched, which reduces the clarity of the lens and affects the normal operation of the inspection robot.

[0006] In order to achieve the above objectives, the present invention adopts the following technical solutions: a smart park inspection robot, comprising:

[0009] The mounting bar is rotatably connected to the lens end of the camera, and a scraper for cleaning the lens is fixedly installed on the side close to the camera lens. A transmission shaft is installed on the top of the camera through the rotation of the drive motor, and the end of the transmission shaft away from the drive motor is fixedly connected to one end of the mounting bar.

[0010] A water tank is fixedly installed on the top of the camera, and a water pump is fixedly installed in the inner cavity. A connecting hose is fixedly installed on the water outlet end of the water pump. A spray pipe is fixedly installed along the longitudinal direction on the side of the mounting strip close to the camera lens. A plurality of spray heads connected to the inner cavity of the spray pipe are fixedly installed on the outer wall of the spray pipe. The end of the connecting hose away from the water pump is fixedly connected to the outer wall of the spray pipe.

[0011] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:

[0016] The length of both ends of the scraper should not be less than the diameter of the camera lens.

[0017] As a further description of the above technical solution:

[0018] A mounting box is fixedly installed on the top of the camera, and a through hole is opened at the end of the mounting box close to the camera lens.

[0030] 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.

[0031] Reference Figure 1-5 , an embodiment provided by the present utility model: a smart park inspection robot, comprising;

[0032] The robot body 1 adopts advanced sensor technology and artificial intelligence algorithms, and can achieve real-time detection of the environment, image analysis, face recognition, intelligent navigation, voice recognition and other functions. During the inspection process, the robot body 1 can accumulate data through equipment such as laser radar and ultrasonic sensors, and perform power consumption and temperature detection on the equipment, thereby increasing the service life of the equipment and reducing the cost of manpower maintenance. In addition, the robot body 1 can also communicate and exchange with personnel through voice interaction, intelligent voice recognition and other technologies, making it convenient for personnel to view real-time inspection records with the robot (this is the working process and working principle of the robot body 1 and the advantages of using the robot body 1. It is a technical means well known to those skilled in the art and will not be elaborated on here).

[0033] The outer wall of the camera 2 is fixedly connected to the rotating part of the robot body 1, wherein the rotating part is installed on the top of the robot body 1, and the outer wall of the camera 2 is fixedly connected to the rotating part. The lens direction of the camera 2 can be adjusted through the rotating part, which is conducive to shooting and detecting equipment located in different directions in the park.

[0034] The mounting bar 6 is rotatably connected to the lens end of the camera 2. A scraper 12 for cleaning the lens is fixedly installed on the side close to the lens of the camera 2. The side of the scraper 12 away from the mounting bar 6 is in contact with the lens of the camera 2. The top of the mounting bar 6 is rotatably connected to the outer wall of the camera 2. When the mounting bar 6 swings at one end, one side of the scraper 12 scrapes off the dust on the outer wall of the lens, thereby cleaning the dust attached to the outer surface of the lens.

[0035] A transmission shaft 11 is installed on the top of the camera 2 through the rotation of the drive motor. The transmission shaft 11 is away from the drive motor (the drive motor controls the rotation direction of its own rotor through the H-bridge circuit. The H-bridge circuit is the most common method to control the direction of a DC motor. It is composed of four switches (usually transistors or relays). These switches can control the flow direction of current at both ends of the motor. When the current flows to the motor from one direction, the motor rotates in one direction. When the current direction changes, the motor rotates in the opposite direction. By alternately changing the direction of the current, the reciprocating motion of the motor can be achieved. ‌) is fixedly connected to one end of the mounting bar 6. After starting the drive motor, one end of the mounting bar 6 rotates with the power output end of the drive motor. When the mounting bar 6 rotates to a certain position, the direction of the current flowing through the drive motor is changed, thereby changing the rotation direction of the power output end of the drive motor, thereby achieving reciprocating swinging of the mounting bar 6, which is beneficial for scraping off dust attached to the outer surface of the lens.

[0036] The water tank 3 is fixedly mounted on the top of the camera 2, and a water pump 15 is fixedly mounted in the inner cavity, a connecting hose is fixedly mounted on the water outlet end of the water pump 15, a spray pipe 13 is fixedly mounted on the side of the mounting strip 6 close to the lens of the camera 2 along the longitudinal direction, a plurality of spray heads 14 connected to the inner cavity of the spray pipe 13 are fixedly mounted on the outer wall of the spray pipe 13, and one end of the connecting hose away from the water pump 15 is fixedly connected to the outer wall of the spray pipe 13. When the driving motor is started, the water pump 15 is started accordingly. At this time, the cleaning liquid inside the water tank 3 enters the water pump 15 through the water inlet end of the water pump 15 and enters the connecting hose through the water outlet end. The cleaning liquid after entering the connecting hose enters the inside of the spray pipe 13. The water pressure inside the spray pipe 13 continues to increase, and the cleaning liquid inside the spray pipe 13 is sprayed on the outer surface of the lens through multiple spray heads 14. At this time, the degree of aggregation of the cleaning liquid on the outer surface of the lens is greater than its own tension, and then falls along the outer surface of the lens under the action of gravity. At this time, the cleaning liquid that falls from the dust on the outer surface of the lens is separated from the outer surface of the lens, and the dust remaining on the outer surface of the lens expands to a soft state after absorbing the cleaning liquid, thereby reducing the hardness of the dust. When the scraper 12 swings with the mounting bar 6, the cleaning liquid and dust remaining on the outer surface of the lens can be scraped off, preventing the outer surface of the lens from being scratched, improving the clarity of the lens, and reducing the adverse effects on the normal operation of the robot body 1.

[0037] The side of the scraper 12 away from the mounting strip 6 is set to a conical structure, which can reduce the contact area between one side of the scraper 12 and the outer surface of the lens, thereby greatly reducing the friction between the scraper 12 and the outer surface of the lens when it swings left and right, and improving the smoothness of the scraper 12 when it swings left and right.

[0038] A water inlet pipe 5 connected to the inner cavity of the water tank 3 is fixedly installed on the top of the water tank 3, and a sealing plug 4 is movably installed on the top of the water inlet pipe 5. Cleaning liquid can be added to the inside of the water tank 3 through the water inlet pipe 5, which is conducive to timely filling of the cleaning liquid. After the cleaning liquid is filled, the sealing plug 4 is inserted into the inside of the water inlet pipe 5 from the top of the water inlet pipe 5, which effectively prevents the cleaning liquid inside the water tank 3 from spilling to the outside of the water tank 3 through the water inlet pipe 5 when the camera 2 rotates with the rotating part.

[0039] Furthermore, the sealing plug 4 is made of rubber material, which can increase the friction between the outer wall of the sealing plug 4 and the inner wall of the water inlet pipe 5, thereby improving the stability of the sealing plug 4 when installed inside the water inlet pipe 5.

[0040] The length of both ends of the scraper 12 is not less than the diameter of the camera 2 lens, and the length of both ends of the scraper 12 is greater than the diameter of the camera 2 lens. When the scraper 12 swings, it can fully cover the outer surface of the lens, effectively preventing dust from remaining on the outer surface of the lens.

[0041] A mounting box 7 is fixedly installed on the top of the camera 2. A through hole is provided at one end of the mounting box 7 close to the lens of the camera 2. The end of the transmission shaft 11 away from the mounting bar 6 passes through the through hole and extends into the inner cavity of the mounting box 7, and a worm gear 9 is fixedly installed on the end of the transmission shaft 11 extending to the inside of the mounting box 7. The driving motor is fixedly connected to the inner wall of the mounting box 7, and a worm 8 meshing with the worm gear 9 is fixedly installed at the power output end of the driving motor. When the driving motor is started, the worm 8 at the power output end of the driving motor rotates accordingly. At this time, the worm wheel 9 rotates with the worm 8, and the worm 8 plays a one-way limiting role on the worm wheel 9. When the worm 8 stops rotating, the worm 8 can position the worm wheel 9, effectively preventing the scraper 12 from rotating again under the action of gravity.

[0042] The outer wall of the transmission shaft 11 is fixedly sleeved with a driving bearing 10, and the outer wall of the driving bearing 10 is fixedly connected to the inner wall of the through hole. The driving bearing 10 can support the transmission shaft 11, prevent the transmission shaft 11 from shaking when rotating, reduce the resistance of the transmission shaft 11 when rotating, and improve the stability and smoothness of the rotation of the transmission shaft 11.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
