Description

Technical Field

[0001] This utility model relates to the field of warning equipment technology, specifically a mobile multifunctional intelligent warning device. Background Technology

[0002] The multifunctional smart warning device is a modern safety early warning device that integrates multiple sensing technologies and intelligent algorithms. It aims to provide users with environmental hazard warnings through various means (visual, auditory, tactile, etc.).

[0003] It is commonly used in fields such as industrial safety production and smart city construction. Its location is adjusted in real time according to the requirements of construction. Therefore, the mobility of the warning device is required. However, after analyzing the existing warning devices, it was found that most of them use triangular brackets for support and positioning. When moving them, they are mostly moved manually by hand. The problem is that for some warning devices with larger dimensions or more functional structures, it is inconvenient to move them, and they lack effective fixing functions when stopped.

[0004] Therefore, in view of the above-mentioned problems, this technical solution designs a mobile multifunctional intelligent warning device. Utility Model Content

[0005] The purpose of this invention is to provide a mobile, multifunctional intelligent warning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mobile multifunctional smart warning device includes a base, a warning board, a control box, a monitoring camera, and a photovoltaic panel. A vertical main pole is installed on the top of the base, a control box is installed on the upper side of the main pole, a warning board is set on one side of the control box, a monitoring camera is installed on the main pole located on the upper side of the control box, a photovoltaic panel is installed on the top of the main pole through a photovoltaic panel bracket, and a moving component that can be controlled by stepping on the bottom of the base is provided.

[0008] The photovoltaic panel output is connected to the input of the solar controller / charger inside the control box to convert solar energy into DC power and supply it to the control box. The base is equipped with a storage battery, and the positive and negative terminals of the storage battery are connected to the battery output of the solar controller / charger inside the control box. The solar controller stores the power generated by the photovoltaic panel in the storage battery and prevents overcharging and over-discharging.

[0009] The control box is connected to the warning board via RS-485 bus, network cable (Ethernet), or wirelessly. The control box provides power to the warning board and sends commands to the warning board via communication lines, thereby displaying the corresponding warning messages on the warning board.

[0010] The surveillance camera is electrically connected to the control box via a network cable, and the battery powers the surveillance camera to control its operation, capture images, and receive information from the surrounding environment.

[0011] The control box is connected to the external network and management center via fiber optic, wireless or network cable to enable remote monitoring, management, receiving instructions, and uploading data (such as video clips and status information) to the cloud or central management platform.

[0012] Through the coordinated operation of the above-mentioned structure and components, this device can achieve real-time environmental monitoring and provide safety warnings.

[0013] At the same time, the moving component is moved by the control device under the operation of the construction personnel, and a real-time stop operation is performed simultaneously.

[0014] The moving assembly includes two symmetrically distributed rear steering wheels on the rear side of the base bottom. These rear steering wheels support the movement of the base and can also be adjusted in angle. Two sets of symmetrically distributed front moving wheels are located on the front side of the base bottom. An axle is installed between the centers of the two sets of front moving wheels, and a foot-controlled brake is installed in the middle of the axle. This means that by applying downward pressure with the foot, the rotation of the axle is restricted, and then a lateral thrust is applied to fix the restricting force, thus ensuring that the axle is stably restricted for a long time. To release the restriction, the opposite lateral thrust is applied again with the foot. This allows for stable and convenient starting and stopping by simple foot operation when moving the base and main rod and other structures as a whole.

[0015] Compared with the prior art, the beneficial effects of this utility model are: through the design of the movable components, the device can be moved flexibly, which is suitable for immediate adjustment at the construction site and reduces the burden of manual handling.

[0016] The foot-controlled brake mechanism allows for single-foot operation to limit and unlock the wheel axle, ensuring rapid start-stop and stable fixation during device movement and avoiding the risk of slippage.

[0017] By connecting the photovoltaic panels to the control box and integrating the battery, the device achieves self-powered solar energy, extending its operating time in environments without external power and preventing overcharging and over-discharging.

[0018] By connecting the control box with the warning board and monitoring cameras, real-time monitoring of environmental data, dynamic display of warning information, and data uploading to the remote management platform are realized, thereby improving the level of intelligence in safety early warning.

[0019] By using a return spring to elastically reset the swing plate and a self-locking design of the positioning pin in the positioning hole, the brake state is reliably maintained, reducing the risk of accidental deactivation. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Please see Figures 1-4 A mobile multi-functional smart warning device includes a base 10, a warning board 11, a control box 12, a monitoring camera 13, and a photovoltaic panel 15. A vertical main pole 14 is installed on the top of the base 10, the control box 12 is installed on the upper side of the main pole 14, the warning board 11 is set on one side of the control box 12, the monitoring camera 13 is installed on the main pole 14 located on the upper side of the control box 12, and the photovoltaic panel 15 is installed on the top of the main pole 14 through the photovoltaic panel bracket 16. At the same time, a moving component that can be controlled by stepping is set at the bottom of the base 10.

[0032] The output terminal of the photovoltaic panel 15 is connected to the input terminal of the solar controller / charging controller inside the control box 12, which is used to convert solar energy into DC power and deliver it to the control box 12. The base 10 is equipped with a storage battery, and the positive and negative terminals of the storage battery are connected to the battery output terminal of the solar controller / charging controller inside the control box 12. The solar controller stores the power generated by the photovoltaic panel 15 in the storage battery and prevents overcharging and over-discharging.

[0033] The control box 12 is connected to the warning board 11 via RS-485 bus, network cable (Ethernet), or wirelessly. The control box 12 provides power to the warning board 11 and sends instructions to the warning board 11 through the communication line, thereby displaying the corresponding warning message on the warning board 11.

[0034] The surveillance camera 13 is electrically connected to the control box 12 via a network cable. At the same time, the battery supplies power to the surveillance camera 13 and controls the operation of the surveillance camera 13 to capture and receive information from the surrounding environment.

[0035] The control box 12 is connected to the external network and management center via fiber optic, wireless or network cable to realize remote monitoring, management, receiving instructions, and uploading data (such as video clips and status information) to the cloud or central management platform;

[0036] Through the coordinated operation of the above-mentioned structure and components, this device can achieve real-time environmental monitoring and provide safety warnings.

[0037] At the same time, the moving component is moved by the control device under the operation of the construction personnel, and a real-time stop operation is performed simultaneously.

[0038] The moving assembly includes two symmetrically distributed rear steering wheels 17 on the rear side of the bottom of the base 10. The rear steering wheels 17 support the movement of the base 10 and can also be adjusted in angle. Two sets of symmetrically distributed front moving wheels 18 are located on the front side of the bottom of the base 10. A wheel axle 19 is installed between the centers of the two sets of front moving wheels 18. A foot-controlled brake is provided in the middle of the wheel axle 19. That is, the wheel frames 20 of the rear steering wheels 17 and the front moving wheels 18 are installed on the bottom of the base 10 through the wheel axle 19 and the swing shaft 25. The wheel axle 19 of the front moving wheels 18 has a rotating rod of the foot-controlled brake in the middle. By applying downward pressure to it with a person's foot, the rotation of the wheel axle 19 is restricted. Then, a lateral thrust is applied to fix the restricting force, thereby ensuring that the wheel axle 19 is stably restricted from rotation for a long time. When the restriction is released, the reverse lateral thrust is applied again with the foot. In this way, when pushing the base 10 and the main rod 14 and other structures to move as a whole, stable and convenient start and stop can be achieved by simple foot operation.

[0039] In embodiments of the present invention, such as Figures 4-6As shown, the foot-controlled brake includes a rotating rod with a diameter smaller than that of the axle 19, installed in the middle of the axle 19. A brake wheel 26 is fixedly installed in the middle of the rotating rod. A set of arc-shaped brake plates 27 is oscillatingly arranged above the brake wheel 26. A swing plate 21 is connected to the brake plate 27 in the direction of the rear side of the bottom of the base 10. A swing shaft 25 is installed on one side of the top of the swing plate 21. A rotating shaft 1 is rotatably connected to the middle of the swing shaft 25. A fixing block 23 is rotatably connected to the end of the rotating shaft 1. The top of the fixing block 23 is fixed to the bottom of the base 10 by a fixing rod 24. The top of the swing plate 21 is elastically connected to the bottom of the base 10 by a return spring 22. The elastic action of the return spring 22 controls the swing plate 21 and the brake plate 27 to rotate around the rotating shaft 1. The top of 27 is also rotatably connected to a second rotating shaft via a swing shaft 25. The end of the second rotating shaft extends above the rotating rod and is connected downward to an eccentric outer ring 28 via a triangular connecting plate. An eccentric inner ring 29 is rotatably connected to the inner side of the eccentric outer ring 28. The rotating rod moves through the edge of the eccentric inner ring 29. At the same time, an L-shaped pedal 31 is connected radially outward on one side of the eccentric inner ring 29 via a connecting rod 30. That is, the L-shaped pedal 31 is hinged to the swing plate 21. By applying downward pressure to the L-shaped pedal 31, the eccentric inner ring 29 is driven to rotate downward. Then, the eccentric outer ring 28 is controlled to move downward on the second rotating shaft, thereby controlling the brake plate 27 to swing downward and apply pressure to the brake wheel 26, thereby limiting the rotation of the brake wheel 26 and preventing the wheel axle 19 from rotating, thus achieving rotational limit of the front moving wheel 18.

[0040] Meanwhile, a set of T-shaped telescopic rods 32 are movable on the vertical side wall of the L-shaped pedal 31. A positioning pin 33 is installed at the end of the T-shaped telescopic rod 32. A vertical positioning hole rod 34 is installed at the bottom of the base 10 on one side of the L-shaped pedal 31. Multiple positioning holes 35 are opened in the lower part of the side wall of the positioning hole rod 34. When downward pressure is applied to the L-shaped pedal 31, the L-shaped pedal 31 is controlled to swing. When the brake plate 27 is controlled to contact the brake wheel 26, the T-shaped telescopic rod 32 moves to the side of the corresponding positioning hole 35. Then, the foot applies a lateral pushing force to the T-shaped telescopic rod 32 to insert the positioning pin 33 into the positioning hole 35 and fix the L-shaped pedal 31. Then, with the help of the return spring 22, the return pushing force of the L-shaped pedal 31 is used to keep the positioning pin 33 in the positioning hole 35 with a certain upward pushing force, thereby limiting the risk of the positioning pin 33 easily dislodging from the positioning hole 35. The multiple vertically arranged positioning holes 35 are used to realize the positioning position when the brake plate 27 and the brake wheel 26 are in contact with different forces.

[0041] Specifically, a T-shaped push rod 36 is movably provided at the end of the positioning hole rod 34 away from the positioning pin 33. When it is necessary to disengage the positioning pin 33 from the positioning hole 35, the foot applies a disengagement force to the T-shaped push rod 36 toward the positioning pin 33 until the positioning pin 33 is disengaged from the positioning hole 35.

[0042] In one embodiment of the present invention, corrugated strips are uniformly formed on the outer circumference of the brake wheel 26 to increase the limiting resistance between it and the brake plate 27.

[0043] It should be noted that since the focus of this technical solution is to solve the problem of convenient stopping and moving of the base 10, the specific connection and operation relationship of components such as the warning board 11, control box 12, monitoring camera 13, and photovoltaic panel 15 can be implemented with reference to existing technologies, and will not be elaborated here.

[0044] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control.

[0045] Alert function execution process:

[0046] The photovoltaic panel 15 is installed on the top of the main pole 14 via the photovoltaic panel bracket 16, and converts solar energy into DC power, which is then input into the solar controller in the control box 12.

[0047] The solar controller stores electrical energy in the battery inside the base 10 and powers the warning panel 11, the monitoring camera 13 and the control box 12.

[0048] The control box 12 sends instructions to the warning board 11 via RS-485 bus, network cable or wireless connection, and controls the warning board 11 to display preset warning messages such as construction hazard warnings.

[0049] The surveillance camera 13 is connected to the control box 12 via a network cable to collect real-time video data of the surrounding environment, which is then uploaded to the remote management platform via fiber optic / wireless network through the control box 12.

[0050] The control box 12 receives external commands such as warning message updates, enabling remote monitoring and management.

[0051] Moving and fixing operation process:

[0052] When moving: the construction personnel push the base 10, the rear steering wheel 17 supports the base 10 and adjusts the direction of movement, and the front moving wheel 18 rotates through the wheel axle 19 to drive the overall displacement of the device.

[0053] When fixed: Press down on the L-shaped pedal 31 with your foot, and the L-shaped pedal 31 will drive the eccentric inner ring 29 to rotate through the connecting rod 30.

[0054] The eccentric inner ring 29 drives the eccentric outer ring 28 to move downward, pushing the rotating shaft 2 to press down the brake plate 27.

[0055] The brake plate 27 swings around the swing shaft 25 and presses against the corrugated strips on the side of the brake wheel 26 to increase frictional resistance, restrict the rotation of the wheel axle 19, and thus lock the forward moving wheel 18.

[0056] At the same time, the foot pushes the T-shaped telescopic rod 32 laterally, so that the positioning pin 33 is inserted into the positioning hole 35 of the positioning hole rod 34, fixing the position of the L-shaped pedal 31; the return spring 22 applies an upward elastic force to the swing plate 21 to ensure that the positioning pin 33 is not easy to come out of the positioning hole 35.

[0057] When the device is released from its fixed position: the foot pushes the T-shaped push rod 36 toward the positioning pin 33, pushing the positioning pin 33 out of the positioning hole 35; the return spring 22 pulls the swing plate 21 to return to its original position, the brake plate 27 disengages from the brake wheel 26, the wheel axle 19 resumes rotation, and the device can continue to move.

[0058] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0059] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
