DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

Unless otherwise specified, a connection is generally a fixed connection, and fixed connections can be either detachable or non-detachable.

[0031] In the absence of mains electricity or when wiring is difficult, traffic management departments face enforcement challenges primarily in areas such as traffic monitoring, information collection, and communication. Current mobile law enforcement equipment overcomes the power supply challenges faced by traditional, pole-mounted monitoring equipment. However, while existing handheld law enforcement equipment is portable, its stability and image quality may be affected during high-speed movement or in complex environments. To address this issue, the present invention provides a mobile monitoring device suitable for traffic enforcement, providing powerful technical support for traffic management departments in special environments, saving resources and improving law enforcement efficiency.

[0032] like Figures 1 to 3 As shown, the movable monitoring device includes: a vehicle body, a power supply component, a hand-cranked lifting pole 4, a cross arm 7 and a monitoring camera 13.

[0033] Among them, the power supply assembly and the hand-cranked lifting pole 4 are both arranged on the movable vehicle body. Specifically, the hand-cranked lifting pole 4 is arranged at the front end of the vehicle body, and the power supply assembly is arranged at the rear end of the vehicle body. The hand-cranked lifting pole 4 can be raised when in use and can be retracted when not in use to facilitate movement and save manpower. The top of the hand-cranked lifting pole 4 is rotatably connected to the cross arm 7 through a rotating connector 16, and the cross arm 7 is also slidably connected to the rotating connector 16. The surveillance camera 13 is arranged at the edge of one end of the cross arm 7, and the power supply assembly is electrically connected to the surveillance camera 13 for powering the surveillance camera 13. The surveillance camera 13 can adopt a high-resolution intelligent infrared surveillance camera, which supports 360° rotation and has night vision function, and can shoot continuously around the clock and automatically capture violations.

[0034] In this embodiment, the installation height of the surveillance camera can be adjusted at any time through the hand-cranked lifting pole, and the installation orientation of the surveillance camera can be adjusted at any time through the horizontal arm. It can also rotate in all directions to achieve all-round monitoring coverage of far and near, high and low, and eliminate monitoring blind spots. The surveillance camera can be flexibly deployed to any place through the movable body, which can meet the requirements of efficient mobility and high-precision recording at the same time, and is suitable for various law enforcement scenarios such as traffic management, security patrols, and environmental monitoring.

[0035] like Figure 1、 Figure 3 and Figure 4 As shown, in a specific embodiment, the rotating connection member 16 includes an upper flange 161 , a lower flange 162 , a first fixing member (not shown in the figure) and a second fixing member 163 .

[0036] The lower flange 162 is fixed to the top of the hand-cranked lifting pole 4 , and the upper flange 161 and the lower flange 162 are detachably connected via a first fixing member.

[0037] The upper flange 161 comprises a flange plate and a shaped member, with the bottom of the shaped member connected to the upper end surface of the flange plate. The shaped member comprises a top plate and two side panels, the tops of which are connected to opposite ends of the top plate. The lower flange 162 is removably connected to the flange plate of the upper flange 161 via a first fixing member. The cross arm 7 passes through the shaped member of the upper flange 161 and is removably connected to the shaped member of the upper flange 161 via a second fixing member 163. Specifically, the cross arm 7 is removably connected to the shaped member of the upper flange 161 via the second fixing member 163.

[0038] In this embodiment, the first fixing member can be a bolt assembly (including a bolt and a nut), and the second fixing member 163 can be a screw. To reduce the friction generated during rotation between the upper flange 161 and the lower flange 162, a bearing can be provided between the upper flange 161 and the lower flange 162. For example, the inner side surface of the lower flange 162 is connected to the outer ring of the bearing, and the lower end surface of the flange plate of the upper flange 161 protrudes into the bearing and connects to the inner ring of the bearing, or vice versa.

[0039] In a specific embodiment, the cross arm 7 is a square tube, the length of the square tube is 3m to 5m, preferably 3m; the wall thickness of the square tube is 1mm to 2mm, preferably 1.5mm.

[0040] In this embodiment, the horizontal arm 7 can adjust the horizontal rotation angle through the rotating connector 16, and can also be adjusted laterally (also called bidirectional adjustment) through the rotating connector 16, which is convenient and practical, and the span of the lateral adjustment can reach 3m to 5m.

[0041] In a specific embodiment, Figure 5 As shown, the hand-cranked lifting pole 4 includes multiple hollow tubes 44, multiple pulleys 43, steel ropes 42 and a hand-cranked wheel 41. The hand-cranked wheel 41 can adopt an existing mechanical winch.

[0042] Among them, multiple hollow tubes 44 are nested in sequence, and their diameters gradually increase. Figure 5For example, a total of four hollow tubes are set, which are the first hollow tube, the second hollow tube, the third hollow tube and the fourth hollow tube (the last hollow tube) from the inside to the outside. The first hollow tube is located at the innermost part, the second hollow tube is sleeved outside the first hollow tube, the third hollow tube is sleeved outside the second hollow tube, and the fourth hollow tube is sleeved outside the third hollow tube. In other words, the first hollow tube is nested inside the second hollow tube, the second hollow tube is nested inside the third hollow tube, and the third hollow tube is nested inside the fourth hollow tube.

[0043] Each section of the hollow tube, except the last, is provided with a corresponding set of pulleys 43. A hand-cranked wheel 41 is located on the upper outer surface of the last section of the hollow tube. One end of a wire rope 42 is connected to the hand-cranked wheel 41. The other end of the wire rope 42 passes through each set of pulleys 43 from bottom to top and is then secured to the bottom of the first section of the hollow tube. The hand-cranked wheel 41 is configured to rotate in a first direction (e.g., clockwise) to gradually tighten the wire rope 42, causing the first to second-to-last hollow tubes to rise sequentially under the action of the tension of the wire rope 42. It is also configured to rotate in a second direction (e.g., counterclockwise) to gradually release the wire rope 42, causing the first to second-to-last hollow tubes to descend sequentially under the action of their respective gravity.

[0044] In this embodiment, the hollow tube sections are connected by wire ropes 42. Clockwise rotation of the hand crank gradually tightens the wire ropes 42, causing the wire ropes 42 to pull the hollow tube sections upward. Counterclockwise rotation of the hand crank gradually releases the wire ropes 42 (also known as reverse tightening), causing the wire ropes 42 to pull the hollow tube sections downward. This structure allows the hand cranked lifting pole 4 to be raised when in use and retracted when not in use, facilitating movement and saving manpower and costs. It offers a three-in-one combination of safety, convenience, and stability.

[0045] Specifically, when the hand-cranked lifting pole 4 needs to be raised, the hand-cranked wheel 41 is shaken in a clockwise direction (also called forward direction), and the wire rope 42 is gradually tightened, first pulling the first hollow tube upward (i.e., extending from the second hollow tube) until it moves to the first limit position of the first hollow tube, and then the wire rope 42 is tightened, pulling the second hollow tube upward (i.e., the second hollow tube extends from the third hollow tube) until it moves to the first limit position of the second hollow tube, and so on, and the wire mesh 42 is tightened again, pulling the penultimate hollow tube upward (i.e., the penultimate hollow tube extends from the last hollow tube) until it moves to the first limit position of the penultimate hollow tube. At this point, all the hollow tubes from the first hollow tube to the penultimate hollow tube are lifted to their respective first limit positions, and the hand-cranked lifting pole 4 is raised to the highest position. When the hand-cranked lifting pole 4 needs to be lowered, the hand-cranked wheel 41 is cranked counterclockwise (also called reverse), and the wire rope 42 is gradually released. The first section of the hollow tube to the penultimate section of the hollow tube freely drops down in sequence under the action of their respective gravity until all of them drop to their respective second limit positions. At this time, the hand-cranked lifting pole 4 falls back to the lowest position.

[0046] In one embodiment, each pulley set includes an upper pulley and at least one lower pulley (not shown). The upper pulley is disposed on the upper portion of the outer surface of the corresponding hollow tube section 44, and the at least one lower pulley is disposed on the bottom portion of the corresponding hollow tube section 44. The wire rope 42 first passes around the upper pulley corresponding to the hollow tube section 44, and then passes around the at least one lower pulley corresponding to the same hollow tube section 44.

[0047] In this embodiment, by shaking the hand crank 41, the wire rope 42 uses the hand crank 41 on the upper outer surface of the last hollow tube (i.e., the hollow tube with the largest diameter) as a support point to drive the lower pulley of the second-to-last hollow tube through the upper pulley of the second-to-last hollow tube, giving the second-to-last hollow tube an upward pulling force. This pulling force is transmitted through the wire rope 42 to use the upper pulley of the third-to-last hollow tube as a support point to drive the lower pulley of the third-to-last hollow tube, giving the third-to-last hollow tube an upward pulling force, and so on, until the tube is pulled out. The force is transmitted through the steel wire rope 42 to the lower pulley of the first hollow tube section, which is driven by the upper pulley of the first hollow tube section. The pulling force generated by shaking the hand crank 41 will be directly transmitted to the first hollow tube section through the steel wire rope 42, so that the first hollow tube section is pulled up to its first limit position. At this time, continue to shake the hand crank 41, and the second hollow tube section will start to be pulled up, and so on, until the penultimate hollow tube section is also pulled up to its first limit position. At this time, the hand-cranked lifting pole 4 is fully raised, that is, the lifting is realized section by section starting from the first hollow tube section.

[0048] In a specific embodiment, Figure 6As shown, the lower hollow tube 442 and the upper hollow tube 441 of the two adjacent hollow tubes 44 are limited by a limiting member 443. The limiting member 443 can be an existing nylon fixing buckle.

[0049] In this embodiment, when the first hollow tube section to the penultimate hollow tube section is raised in sequence, each hollow tube will be limited by the limit member 443 after reaching its first limit position, preventing each hollow tube from falling out of the next adjacent hollow tube section. Correspondingly, when the first hollow tube section to the penultimate hollow tube section is lowered in sequence, each hollow tube will also be limited by the limit member 443 after reaching its second limit position, preventing each hollow tube from falling into the inside of the next adjacent hollow tube section. The limit member 443 can also prevent the hollow tube from shaking left and right during the rising and descending process. It should be noted that for the same hollow tube section, its first limit position is located at the bottom of the hollow tube, and its second limit position is located at the top of the hollow tube, that is, the second limit position is above the first limit position.

[0050] In a specific embodiment, after the first to the penultimate hollow tube sections are all raised to their respective first limit positions, the height of the hand-cranked lifting pole 4 is 6m to 8m, preferably 6m. After the first to the penultimate hollow tube sections are all lowered to their respective second limit positions, the height of the hand-cranked lifting pole 4 is 1.5m to 2m, preferably 1.8m. That is, the height of the hand-cranked lifting pole 4 is adjustable from 1.5m to 8m.

[0051] Each section of the hollow tube can be a square tube, wherein the cross-sectional dimensions of the first section of the hollow tube can be 50 mm × 50 mm, the cross-sectional dimensions of the second section of the hollow tube can be 60 mm × 60 mm, the cross-sectional dimensions of the third section of the hollow tube can be 80 mm × 80 mm, and the cross-sectional dimensions of the fourth section of the hollow tube can be 100 mm × 100 mm. Of course, each section of the hollow tube can also be a round tube, and accordingly, the outer diameter of the first section of the hollow tube can be 50 mm, the outer diameter of the second section of the hollow tube can be 60 mm, the outer diameter of the third section of the hollow tube can be 80 mm, and the outer diameter of the fourth section of the hollow tube can be 100 mm.

[0052] The wall thickness of each hollow tube 44 is 1 mm to 2 mm, preferably 1.5 mm.

[0053] In a specific embodiment, Figure 1 and Figure 2 As shown, the power supply assembly includes a photovoltaic bracket 6, a photovoltaic power generation assembly 5, a photovoltaic controller 9, and an energy storage battery 8. The photovoltaic bracket 6 can be made of carbon steel. The energy storage battery 8 can be an existing colloidal battery.

[0054] The photovoltaic power generation assembly 5 is mounted on a photovoltaic support 6, which converts absorbed light energy into electrical energy through the photoelectric effect of semiconductors. The photovoltaic support 6 is used to sequentially expand and collapse the multiple photovoltaic panels in the photovoltaic power generation assembly 5, as well as to adjust the elevation angle of the expanded photovoltaic power generation assembly 5. Specifically, after the photovoltaic support 6 sequentially expands the multiple photovoltaic panels, the multiple photovoltaic panels are arranged side by side. After the photovoltaic support 6 sequentially collapses the multiple photovoltaic panels, the multiple photovoltaic panels are arranged in a stacked manner. The photovoltaic support 6 can adjust the elevation angle of the multiple photovoltaic panels arranged side by side to 45°, thereby maximizing the amount of stored electrical energy under the same consumable conditions. The photovoltaic controller 9 is electrically connected to the photovoltaic power generation assembly 5 and the energy storage battery 8, respectively. Through the photovoltaic controller 9, the electrical energy generated by the photovoltaic power generation assembly 5 is input into the energy storage battery 8 for storage. The energy storage battery 8 is also electrically connected to the surveillance camera 13. The energy storage battery 8 can also support AC charging.

[0055] The photovoltaic power generation component 5 is set on the back of the vehicle body. The multiple photovoltaic panels therein can convert light energy into electrical energy and store it in the energy storage battery 8. The photovoltaic power generation component is a retractable photovoltaic power generation component that can be unfolded when in use and folded when not in use to reduce space layout. Figure 1 For example, the photovoltaic power generation component 5 includes three 18V200W photovoltaic panels. When the three photovoltaic panels are unfolded, they are arranged side by side. The total unfolded width can be 2.1m. When the three photovoltaic panels are folded, they are arranged in three layers (ie, stacked into three layers).

[0056] In this embodiment, the vehicle body is equipped with high-power and high-efficiency photovoltaic panels and high-efficiency energy storage batteries, which support AC charging and solar-assisted charging, ensuring that the mobile monitoring device can continue to be powered even when there is no sunlight or at night, thereby ensuring the continuous and stable operation of the mobile monitoring device.

[0057] In a specific embodiment, Figure 1 and Figure 2 As shown, the vehicle body includes a traction frame 15, a frame 11, a carriage 14 (also called an equipment compartment) and multiple sets of wheels 3.

[0058] The traction frame 15 can be 0.5m long. The vehicle frame 11 can be 2.2m long and 1m wide. Ventilation holes are provided on at least one side of the vehicle compartment 14. Multiple ventilation holes are evenly distributed along the sides of the vehicle compartment 14. The vehicle compartment 14 can also be self-cleaning. The spacing between each set of wheels 3 can be 1.5m. The vehicle can carry a maximum load of 40kg.

[0059] Among them, the traction frame 15 is detachably connected to the vehicle frame 11. Specifically, the traction frame 15 is a detachable traction frame, which connects the vehicle body to the motor vehicle through the traction frame 15, and the monitoring device can be moved to any application place at any time under the drive of the motor vehicle. The hand-cranked lifting pole 4 and the carriage 14 are both arranged on the vehicle frame 11. Multiple sets of wheels 3 are arranged at the bottom of the frame 11, the photovoltaic bracket 6 and the photovoltaic power generation component 5 are arranged on the top of the carriage 14, and the photovoltaic controller 9 and the energy storage battery 8 are arranged inside the carriage 14. In addition, the placement position of the photovoltaic power generation component 5 can be flexibly adjusted. According to the actual implementation scenario, the photovoltaic power generation component 5 can be placed on the photovoltaic bracket 6, or the photovoltaic power generation component 5 can be placed directly on the top of the carriage 14 at a certain angle (such as 45°).

[0060] In this embodiment, since the entire monitoring device can be flexibly moved, there is no need for fixed points and wiring, which reduces the deployment cost. Moreover, the entire monitoring device is designed to be lightweight and easy to install and disassemble, and can be flexibly deployed in various locations that require temporary monitoring or law enforcement, such as road intersections, large event venues, construction areas, etc.

[0061] In a specific embodiment, Figure 2 As shown, the mobile monitoring device further includes an inverter 10 and an industrial intelligent gateway 12. The photovoltaic power generation component 5, the photovoltaic controller 9, the energy storage battery 8 and the inverter 10 constitute a photovoltaic power generation system.

[0062] Among them, the inverter 10 and the industrial intelligent gateway 12 are arranged inside the carriage 14. The inverter 10 is electrically connected to the energy storage battery 8 and the industrial intelligent gateway 12 respectively. The energy storage battery 8 outputs 220V AC power through the inverter 10 to power the industrial intelligent gateway 12, and can also power other loads.

[0063] The industrial intelligent gateway 12 has an embedded IoT card and is wirelessly connected to the surveillance camera 13 via a wireless network, for example, a 5G wireless network to transmit high-definition video surveillance data. The surveillance camera 13 can rotate in all directions to collect real-time video information from all directions, perform real-time analysis on the collected images to identify one or more of preset behaviors, preset objects, and preset events, and transmit the collected real-time video information and identified information to a cloud server or command center via the industrial intelligent gateway 12. The industrial intelligent gateway can be replaced by an RTU (Remote Terminal Unit).

[0064] In this embodiment, advanced wireless communication technology is used to transmit real-time image and video data captured by surveillance cameras to a cloud server or command center via an industrial intelligent gateway, enabling remote monitoring and analysis. The surveillance camera can rotate 360° to capture video information from all directions. It can also integrate an AI (Artificial Intelligence) algorithm for real-time analysis of captured footage. It can accurately identify preset behaviors (such as traffic violations), preset objects (such as license plates), and preset events (such as specific violations), improving law enforcement efficiency and accuracy.

[0065] After the motor vehicle pulls the movable monitoring device to the scene, it first unfolds the photovoltaic power generation components on the back of the vehicle in sequence, then raises the hand-cranked lifting pole at the front to the required height, and then wirelessly connects the monitoring camera, industrial intelligent gateway and cloud server or command center in sequence, and the monitoring device can be put into use.

[0066] In a specific embodiment, Figure 1 and Figure 2 As shown, the vehicle body further includes a single-wheel support assembly 1 and a parking support assembly 2.

[0067] The wheel support assembly 1 is arranged at the bottom of the traction frame 15 to support the traction frame 15. The parking support assembly 2 is arranged at the bottom of the frame 11, specifically at the four corners of the bottom of the frame 11, to support the frame 11.

[0068] In this embodiment, by arranging a single-wheel support assembly 1 at the bottom of the traction frame in front of the frame and arranging parking support assemblies 2 at the four corners of the bottom of the frame, the entire monitoring device can be effectively supported after the movable monitoring device is in place, thereby increasing stability during parking and reducing the pressure on the wheels.

[0069] In one embodiment, the wheel support assembly 1 includes a universal wheel and a first lever mechanism (e.g., a jack). The first lever mechanism is respectively connected to the universal wheel and the bottom of the traction frame 15, and is used to raise and lower the traction frame 15.
