Description

Technical Field

[0001] This utility model relates to the field of robotics technology, and in particular to a security patrol sentry robot. Background Technology

[0002] With the continuous and rapid development of my country's construction industry, the issue of safety management at construction sites has become increasingly prominent, placing higher demands on the safety and management efficiency of the construction environment. Traditional construction site safety management methods mainly rely on manual inspections and fixed video surveillance, which have shortcomings such as slow response speed, low inspection efficiency, and limited coverage. Especially in special environments such as complex terrain, inclement weather, or nighttime operations, it is difficult to achieve all-weather, all-round safety monitoring and early warning.

[0003] In recent years, with the continuous maturation of new technologies, new technical support and solutions have been provided for the construction of smart construction sites. As an important carrier of intelligent management, inspection robots have been gradually introduced into the safety management of construction sites, promoting the development of construction site inspection work towards automation and intelligence.

[0004] However, most existing inspection robots employ a wheeled locomotion structure, exhibiting significant adaptability limitations in complex outdoor environments. For instance, on challenging terrains common at construction sites, such as barren slopes, grasslands, and gravel areas, naturally growing grass stalks or scattered gravel can easily become stuck between the drive wheels, obstructing or even jamming the robot. If the robot comes to a sudden stop after jamming, it may tip over due to inertia. Furthermore, it is prone to sinking into soft, muddy, or rugged terrain. This not only affects the continuity of inspection tasks but also reduces the stability and applicability of the equipment, limiting its widespread application in complex construction site environments. In addition, existing inspection robots are overly simplistic in function, lacking positioning and on-site monitoring capabilities, and are unable to record inspection trajectories or monitor the environment and personnel behavior in real time.

[0005] In other words, existing technologies need to be improved to enhance the stability and reliability of robots in complex construction environments, as well as their functional versatility. Utility Model Content

[0037] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0038] like Figures 1 to 9 As shown, this application discloses a security patrol sentry robot, including a chassis 1, a body 2 mounted on the chassis 1, and a robotic arm 3 mounted above the body 2. The chassis 1 provides support and movement for the robot. In this embodiment, the robotic arm 3 is a six-axis robotic arm with six degrees of freedom and high flexibility. An image acquisition module 4 is connected to the robotic arm 3. The image acquisition module 4 is a camera. Through the flexible rotation of the robotic arm 3, it can monitor images from various angles on site.

[0039] The design of robotic arm 3 allows the robot to cover a large area, ensuring comprehensive on-site data collection. The acquired image data is transmitted to a data storage unit for recording, providing a basis for subsequent analysis and review.

[0040] The robot body 2 is equipped with a navigation and positioning module. The navigation and positioning module can build an environmental map and realize the robot's real-time positioning. The robot's position in space is determined by the navigation and positioning module and transmitted to the data storage unit for recording, thereby generating a detailed environmental map. This helps the robot to autonomously plan its inspection path and accurately reach the designated location to carry out inspection work.

[0041] The data storage unit is electrically connected to the navigation and positioning module and the image acquisition module 4, and is used to record the inspection trajectory and image data. The data storage unit saves the robot's running trajectory information and a large amount of acquired image data. This data is of great value for subsequent data analysis, troubleshooting, and safety assessment. For example, analyzing the inspection trajectory can help determine whether the robot's working path is reasonable, and reviewing the image data can help identify any abnormalities on-site.

[0042] The track 5 is composed of several articulated track plates 501, each track plate 501 having a receiving portion 5011. The upper surface of the track plate 501 is flat, and the lower surface has reinforcing ribs 9 extending along the width direction. The reinforcing ribs 9 enhance the structural strength of the track plate 501, enabling it to withstand various pressures and frictions during robot operation, thus ensuring the normal service life of the track 5.

[0043] The drive unit includes a first power wheel set 6 and a second power wheel set 7. A motor is installed inside the chassis 1 and connected to a drive shaft. The first power wheel set 6 and the second power wheel set 7 are connected to the drive shaft, thereby driving the first power wheel set 6 and the second power wheel set 7 to rotate through the action of the motor and the drive shaft. Each of the first power wheel set 6 and the second power wheel set 7 has several support positions 601 on its circumference. The support positions 601 are arc-shaped grooves, and the receiving parts 5011 form matching arc-shaped outer surfaces. When the first power wheel set 6 and / or the second power wheel set 7 rotate, the engagement of the support positions 601 and the receiving parts 5011 pushes the track plates 501 to move. This special connection method ensures effective power transmission, enabling the track 5 to run smoothly.

[0044] Tracked walking mechanisms are provided on both sides of the chassis 1. These mechanisms also include several support wheel sets 8, which rotatably contact the inner surface of the track 5. The support wheel sets 8 support the track 5, improving its stability during movement. The first power wheel set 6, the second power wheel set 7, and the support wheel sets 8 are all rotatably connected to the chassis 1.

[0045] like Figure 5 As shown, in this embodiment, the center line connecting the first power wheel set 6 and the second power wheel set 7 is parallel to the center line connecting the support wheel set 8. This layout makes the track walking mechanism more evenly stressed and more stable when walking.

[0046] like Figure 5 as well as Figure 6 As shown, the first drive wheel set 6 and the second drive wheel set 7 protrude laterally from the corresponding support wheel set 8, causing the corresponding track section 5 to have an inclined structure. This design facilitates the robot's ability to climb obstacles of a certain height, enhances its obstacle-crossing capability, and expands its working range.

[0047] A protective cover 10 is installed on the outside of the chassis 1, and the tracked walking mechanism is enclosed within the protective cover 10. The body 2 is mounted on the upper part of the protective cover 10. Side plates 1001 are provided on both sides of the protective cover 10, and a gap is left between the side plates 1001 and the tracked walking mechanism. The protective cover 10 serves to protect the tracked walking mechanism, preventing it from being collided with and damaged by external objects. At the same time, the gaps ensure that the tracked walking mechanism has sufficient space during operation and is not obstructed by the protective cover 10, thus ensuring the normal operation of the robot.

[0048] The chassis 1 is equipped with a lidar 11 and a tilted control display screen 12. The control display screen 12 is positioned above the lidar 11 for easy observation and operation. The lidar 11 is used to acquire environmental information around the robot, assisting the navigation and positioning module in achieving more accurate positioning and environmental perception. The control display screen 12 provides the operator with an intuitive interface, facilitating the setting of various robot parameters, operation of functions, and viewing of the robot's operating status.

[0049] The chassis 1 houses a rechargeable battery that powers the LiDAR 11, control display screen 12, navigation and positioning module, robotic arm 3, image acquisition module 4, data storage unit, and warning lights. The use of a rechargeable battery frees the robot from the constraints of a power cord, enabling it to operate mobilely.

[0050] The communication module 15, mounted on the robot body 2, is used for bidirectional data transmission with the backend system, enabling remote monitoring and command issuance. During robot inspection, the communication module 15 transmits data in real time to the backend system, including robot position information acquired by the navigation and positioning module, on-site image data collected by the image acquisition module 4, and inspection trajectory recorded by the data storage unit. Backend operators can view this information intuitively through monitoring software, enabling remote monitoring of the robot's inspection work.

[0051] Meanwhile, the backend system can also send instructions to the robot through the communication module 15. The bidirectional data transmission function of the communication module 15 enables the robot to be closely connected with the backend system, greatly improving the management efficiency and flexibility of the inspection work.

[0052] The robot body 2 is also equipped with a voice broadcast module and a remote intercom module, with the remote intercom module communicating with the backend system. The voice broadcast module can provide various information prompts during the robot's inspection process, such as playing notices, advertisements, safety slogans, and event introductions, meeting the information delivery needs of different scenarios.

[0053] The remote intercom module enables real-time voice communication between the robot and the back-end system. Back-end operators can communicate with the robot through the remote intercom module to understand the actual situation on-site. For example, when the robot encounters complex situations during inspections and cannot accurately determine the cause, operators can use the remote intercom module to directly inquire about the situation from nearby staff or provide further operational instructions to the robot, ensuring the smooth progress of the inspection work.

[0054] The chassis 1 is equipped with a power on / off switch 13 and an emergency stop switch 14. The power on / off switch 13 controls the overall power supply to the robot. When the robot needs to be started for inspection work, the operator operates the power on / off switch 13 to turn on the robot's power and put it into working mode. After the inspection work is completed, the power on / off switch 13 can be turned off to cut off the robot's power supply, saving energy and ensuring equipment safety. The emergency stop switch 14 is designed to deal with sudden emergencies. During robot operation, if a situation arises that endangers personnel safety, causes equipment damage, or other emergencies, the operator can immediately press the emergency stop switch 14. At this time, the robot will quickly stop all movement. The emergency stop switch 14 is usually designed with a conspicuous color and a large button, allowing the operator to operate it quickly and accurately in an emergency.

[0055] This utility model adopts a tracked walking mechanism, which can adapt to various complex construction site environments, enabling it to easily adapt to various complex construction site environments and possess excellent obstacle crossing capabilities; it also has an image acquisition module 4, a navigation and positioning module, and a data storage unit. The image acquisition module 4 can perform real-time image monitoring of the site, the navigation and positioning module records the inspection trajectory, and the data storage unit is responsible for storing relevant information, providing strong support for construction site management and monitoring.

[0056] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the 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. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
