Description

Technical Field

[0001] This utility model relates to a mobile video monitoring device. Background Technology

[0002] In numerous fields, especially at construction sites for hydropower, thermal power, and building projects, the demand for monitoring specific areas is increasing. However, these areas often present numerous inconveniences or dangers, posing significant challenges to traditional monitoring methods. For example, in inspecting corrosion prevention in underground oil tanks, workers must first empty the tank, then conduct prolonged ventilation to remove oil and gas, followed by using an oxygen meter to check the oxygen concentration. Only after ensuring safety can they enter the tank for photographic inspection. This process is not only cumbersome and time-consuming but also carries potential safety risks. Another example is the inspection of blockages and welds in underground pipelines, which typically relies on industrial endoscopes. However, these endoscopes usually have only 5 megapixels, making it difficult to achieve the required high precision in terms of image clarity. They also struggle to focus on distant objects and lack wide-angle capabilities, thus limiting the monitoring range. Furthermore, the inspection of deep well equipment is even more complex. Workers must use fall arrest hooks while slowly descending into the well, which is not only inefficient but also carries the risk of falling. Therefore, there is an urgent need for a flexible, reliable, and highly efficient monitoring device to meet the monitoring needs in complex environments. Utility Model Content

[0003] The purpose of this invention is to provide a mobile video monitoring device to solve the problems of existing monitoring technologies in dangerous environments or complex terrains, such as safety risks, insufficient flexibility, low clarity, low efficiency, and lack of remote monitoring capabilities.

[0004] To solve the above problems, the technical solution of this utility model is as follows:

[0005] A mobile video monitoring device includes a robot chassis with a through hole and a bracket. A guide wheel is installed on one side of the through hole, and a winch is mounted on the bracket. A winch wire rope passes through the through hole and is connected to a first pan-tilt unit. The winch wire rope overlaps the guide wheel. A first camera is mounted on the first pan-tilt unit. An electrical box is located on the robot chassis, containing a controller and a switch. The electrical box has a touch screen and multiple control buttons. The first camera and the first pan-tilt unit are connected to the switch and the controller sequentially via network cables. The touch screen is connected to the controller's video output interface via a video cable, and the control buttons are connected to the controller's input terminals. The robot chassis is connected to the controller via cables, and the winch is connected to the controller's output terminal.

[0006] Furthermore, a multi-stage electric telescopic rod is installed on the robot chassis, a second gimbal is installed on the top of the multi-stage electric telescopic rod, a second camera is installed on the second gimbal, the second camera and the second gimbal are connected to a switch, and the multi-stage electric telescopic rod is connected to the controller output.

[0007] Furthermore, the winch has two wire ropes and two guide groove wheels, which are respectively arranged on both sides of the through hole.

[0008] Furthermore, the winch includes a frame and a hollow drum. The two sides of the hollow drum are connected to bearing seats on the frame via rotating shafts. The rotating shafts are hollow, and electric slip rings are mounted on the rotating shafts. Steel wire ropes and network cables are wound around the drum. One end of the network cable is connected to the first camera and the first pan-tilt unit. The other end of the network cable passes through the drum and the hollow rotating shaft and is connected to one end of the electric slip ring. The other end of the electric slip ring is connected to a switch via a cable.

[0009] Furthermore, the steel wire rope and the network cable are wrapped with a rubber protective layer.

[0010] Furthermore, the robot chassis is a tracked robot chassis.

[0011] Furthermore, a wireless communication module is installed inside the electrical box, through which the controller wirelessly connects to the terminal device.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Using a robotic chassis as a mobile platform, it can move autonomously in hazardous areas or hard-to-access locations without human intervention, thus significantly reducing the risks faced by workers. For example, in hazardous environments such as underground oil tanks and deep wells, the robotic chassis can carry cameras and, with the assistance of winches, penetrate deep into the interior to conduct monitoring, avoiding direct contact between personnel and potential hazards.

[0014] 2. The robot chassis adopts a tracked design, providing excellent maneuverability and stability, easily handling complex terrains such as muddy roads, steps, and slopes. Simultaneously, the combination of a winch and a multi-stage electric telescopic mast allows the camera to be raised, lowered, and extended over a wide range vertically, further expanding the monitoring range. For example, in monitoring equipment at heights, the multi-stage electric telescopic mast can raise a second camera to a higher position, achieving wide-area monitoring.

[0015] 3. Compared to traditional industrial endoscopes, the camera in this device provides clearer and more stable images, supporting high-resolution and wide-angle shooting, and can capture details more accurately to meet high-precision monitoring needs. For example, in the inspection of underground pipeline welding, the high-pixel camera can clearly capture weld details, helping technicians to detect potential problems in a timely manner.

[0016] 4. By installing a wireless communication module inside the electrical box, the controller can wirelessly connect to terminal devices (such as remote controls, mobile phones, tablets, or computers). Operators can remotely control the movement of the device, the shooting angle and focus of the camera, and view the monitoring footage in real time from a safe area. This function not only improves the convenience of operation but also removes the time and space constraints on monitoring work, greatly improving work efficiency.

[0017] 5. Traditional monitoring methods often require a significant investment of manpower, resources, and time. For example, inspecting underground oil tanks requires the collaboration of multiple people, and the preparation work is cumbersome and time-consuming. In contrast, the mobile video monitoring device of this invention can be deployed quickly and complete monitoring tasks autonomously, reducing manpower investment and preparation work, thereby effectively reducing monitoring costs and time.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5As shown, a mobile video monitoring device includes a robot chassis 1. A through hole 13 and a bracket are provided on the robot chassis 1. A guide wheel 5 is installed on one side of the through hole 13 to guide a steel wire rope 14 and prevent it from deviating from its track during movement. A winch 6 is installed on the bracket. The winch steel wire rope 14 passes through the through hole 13 and connects to a first gimbal 12. The steel wire rope 14 of the winch 6 is attached to the guide wheel 5. A first camera 11 is installed on the first gimbal 12. The shooting angle is adjusted by the rotation and tilt functions of the first gimbal 12. An electrical box 8 is installed on the top, containing a controller and a switch. The electrical box 8 has a touchscreen 9 and multiple control buttons 10. The first camera 11 and the first pan-tilt unit 12 are connected to one of the switch's RJ45 ports via a network cable 17 (e.g., RS-485). The other RJ45 port of the switch is connected to the controller. The touchscreen 9 is connected to the controller's video output interface via an HDMI video cable. The control buttons 10 are connected to the controller's input terminals. The robot chassis 1 is connected to the controller via a CAN bus and a power cable. The winch 6 is connected to the controller's output terminal via a relay. Below the through-hole 13, the robot chassis 1 has a space to accommodate the camera. When the robot chassis 1 moves, the winch 6 pulls the camera back into this space to avoid interfering with the robot chassis 1's movement. A battery is located inside the robot chassis 1 to power the entire monitoring device.

[0027] The controller used is an Advantech UNO series industrial computer, which is highly stable, has strong anti-interference capabilities, and is suitable for industrial environments.

[0028] The switch should be either a TP-LINK TL-SG105E 5-port Gigabit model or a Mercury network security switch to meet the network data transmission needs of multiple devices.

[0029] The camera selected is the Hikvision DS-2CD3T47WD-L HD wide-angle model, equipped with a fill light to ensure the clarity of the monitoring image.

[0030] The gimbal uses Uniview's USG6260, which allows for flexible adjustment of the shooting angle.

[0031] The Touchscreen 9 is compatible with Guangzhou Dacai serial port resistive touchscreens, and the former is easy to operate via serial port connection.

[0032] The wireless communication module selected is the Quectel EC20 4G module (remote transmission).

[0033] Robot chassis 1 uses Leishen Intelligent LM-AGV industrial chassis.

[0034] The working process of this utility model is as follows: Taking the corrosion inspection of underground oil tanks as an example, such as... Figure 4As shown, the robot chassis 1 is moved above the manhole of the oil tank by the control buttons, so that the through hole 13 is aligned with the manhole. Then, the winch 6 is controlled to lower the steel cable 14 to lower the first gimbal 12 and the camera into the oil tank. Then, the staff controls the first gimbal 12 and the camera to take pictures and inspect the inner wall of the oil tank through the touch screen 9. After the inspection is completed, the winch 6 and the steel cable 14 pull the first gimbal 12 and the camera back into space, completing the inspection of the oil tank.

[0035] A multi-stage electric telescopic mast 2 is mounted on the robot chassis 1. A second gimbal 3 is mounted on top of the multi-stage electric telescopic mast 2, and a second camera 4 is mounted on the second gimbal 3. The second camera 4 and the second gimbal 3 are connected to the RJ45 port of a switch, and the multi-stage electric telescopic mast 2 is connected to the controller output. When it is necessary to inspect equipment at a high position, the multi-stage electric telescopic mast 2 can be raised via the touch screen 9, and then the second gimbal 3 and the second camera 4 can be controlled to take pictures and inspect the equipment at the high position.

[0036] like Figure 1 As shown, the winch 6 has two steel wire ropes 14, and two guide pulleys 5, which are respectively arranged on both sides of the through hole 13. The two steel wire ropes 14 simultaneously raise and lower the first gimbal 12 and the camera, which can prevent the first gimbal 12 and the camera from rotating on their own and facilitate operation.

[0037] like Figure 2 As shown, the winch 6 includes a frame and a hollow drum 15. The hollow drum 15 is connected to bearing seats on the frame via rotating shafts on both sides. The rotating shafts are hollow, and electric slip rings 16 are mounted on them. A steel wire rope 14 and a network cable 17 are wound around the drum 15. One end of the network cable 17 is connected to the first camera 11 and the first pan-tilt unit 12. The other end of the network cable 17 passes through the drum 15 and the hollow rotating shaft and connects to one end of the electric slip ring 16. The other end of the electric slip ring 16 is connected to a switch via a cable. The design of the hollow drum 15 and the electric slip ring 16 prevents the network cable 17 from getting tangled or damaged during the winch process, ensuring stable transmission of video signals. At the same time, combining the steel wire rope 14 and the network cable 17 simplifies the structure of the device and improves its overall compactness.

[0038] The steel wire rope 14 and the network cable 17 are wrapped with a rubber protective layer 18. The rubber protective layer 18 protects the network cable 17 and prevents it from being damaged during the winding process of the drum 15.

[0039] The robot chassis 1 is a tracked robot chassis 1. It has good passability and stability, and can easily cope with complex terrain, such as muddy roads, steps, slopes, etc.

[0040] A 4G wireless communication module is installed inside the electrical box 8, through which the controller wirelessly connects to the terminal device. By installing the wireless communication module inside the electrical box 8, the controller can wirelessly connect to the terminal device (such as a remote control, mobile phone, tablet or computer). Operators can remotely control the movement of the device, the shooting angle and focus of the camera, etc., from a safe area, and view the monitoring screen in real time.

[0041] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
