DETAILED DESCRIPTION

[0026] The following is a further detailed description of a mobile hot work site monitoring device proposed by the utility model in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become more apparent according to the following description and claims.

[0027] See also Figure 1 to Figure 2 This embodiment provides a mobile hot work site monitoring device, which is used to realize hot work monitoring in complex environments and automatically issue alarms based on monitoring results to prevent damage to personnel and property safety.

[0028] A mobile hot work site monitoring device includes a chassis 1, an imaging component and a central control module 12, wherein casters are respectively arranged at the bottom corners of the chassis 1, and a hand-held handle 4 is arranged on the side wall of the chassis 1. The casters are Foma wheels 14, i.e., a horizontally adjustable support type caster, which has a better bearing capacity during the movement and can withstand a large impact and vibration load, thereby ensuring the smooth movement of the monitoring device. At the same time, the Foma wheel 14 can be adjusted in height, so that after the monitoring device is determined to be placed, the Foma wheel 14 can be adjusted to place the monitoring device stably and firmly on an uneven ground environment. Through the cooperation of the casters and the hand-held handle 4, the flexible movement and stable fixation of the monitoring device can be easily achieved.

[0029] A partition is horizontally provided inside the chassis 1 along the height extension direction of the chassis 1. The partition divides the internal space of the chassis 1 into relatively isolated and independent first and second chambers, and provides additional structural support for the chassis 1, thereby enhancing the overall stability and durability of the chassis 1. The first chamber and the second chamber are respectively used to place different electrical equipment, ensuring the independence of the electrical equipment in each chamber and a non-interfering operating environment.

[0030] The imaging component includes a camera 7 and a telescopic component. The bottom of the telescopic component is fixed in the bottom plate of the chassis 1. A partition opening is provided in the center of the partition. The telescopic component extends along the height direction of the chassis 1 and is arranged through the partition opening. The telescopic component is configured to be able to extend or contract a certain length along the height extension direction of the chassis 1. The camera 7 is fixed to the top of the telescopic component. In this embodiment, when the monitoring device is in the storage state, the telescopic component contracts along the height extension direction of the chassis 1, driving the camera 7 to be deployed in the first chamber. When the monitoring device is in the operating state, the telescopic component extends along the height extension direction of the chassis 1, driving the camera 7 to move to the outside of the first chamber, that is, to the upper space of the chassis 1. Specifically, the telescopic assembly includes a telescopic rod 8 and a fixed bracket 2. The fixed bracket 2 is arranged in the second chamber. The bottom of the fixed bracket 2 is fixedly connected to the bottom plate of the chassis 1. The top of the fixed bracket 2 is penetrated by a partition opening and its periphery is fixedly connected to the inner wall of the partition opening, thereby achieving the fixing effect of the fixed bracket 2. A hollow cavity extending along the length direction of the fixed bracket 2 is provided inside the fixed bracket 2. The telescopic rod 8 can be inserted into the hollow cavity and can slide along the hollow cavity. A locking screw is penetrated through the side wall of the tube body at the top of the fixed bracket 2. After confirming that the telescopic rod 8 is in a relative position in the fixed bracket 2, the locking screw can be adjusted to make the bottom surface of the locking screw abut against the outer wall of the telescopic rod 8, thereby achieving the height fixation of the telescopic rod 8 and the camera 7 fixed to the top of the telescopic rod 8. In this embodiment, the maximum adjustment height of the camera 7 is 2.5m.

[0031] Preferably, the camera 7 adopts a dual-spectrum camera, which can be used to realize visible light imaging and infrared thermal imaging functions. Through the dual-spectrum detection technology, the detection accuracy of hot work is better and the scope of application is wider.

[0032] By setting the imaging component with adjustable height in the present embodiment, the imaging component can be stored in the chassis 1 during the transportation of the monitoring device, thereby reducing the space occupied by the monitoring device. During the operation of the monitoring device, the imaging component can flexibly adjust the height of the camera 7 according to the on-site environment. The higher arrangement of the camera 7 can greatly increase the camera field of view of the camera 7, so that it can capture scene information of a larger area, and reduce the obstruction of the field of view by obstacles, so that the monitoring blind area of ​​the monitoring device in the present embodiment is smaller and the monitoring efficiency is higher.

[0033] The central control module 12 is arranged in the second chamber and is electrically connected to the camera 7. It is used to receive the image information taken by the camera 7 in real time, and automatically identify the current image information through the intelligent AI algorithm, automatically judge the image information such as the fire point, illegal fire operation and personnel absence, and issue an alarm, so as to realize the intelligent monitoring function of the monitoring equipment.

[0034] Preferably, the chassis 1 is provided with a first flap 6 and a second flap 10 at the top and the side of the first chamber respectively, and the first edge of the first flap 6 and the opposite edge of the top opening of the chassis 1 can be rotatably connected by a hinge, and the maximum opening and closing angle is 90°. When the first flap 6 is fully opened, the camera 7 can be moved to the space above the first chamber under the drive of the telescopic rod 8. At the same time, the first flap 6 is also fixed with a support member 5 on both side edges adjacent to the first edge, and the other ends of the support member 5 are fixedly connected to the opposite edges of the top opening of the chassis 1 respectively. The support member 5 can use gas pressure or spring force to provide supporting force for the first flap 6, so that when the first flap 6 is not subjected to external force, the support member 5 can support the first flap 6 to maintain a fixed angle to prevent the first flap 6 from falling off by itself and causing damage to the camera 7 and the telescopic rod 8. The second flip cover 10 is arranged on the side wall of the chassis 1. The bottom edge of the second flip cover 10 and the opposite edge of the side opening of the chassis 1 can also be rotatably connected by hinges. The maximum opening and closing angle is 90°. The second flip cover 10 is used to open the first chamber from the side of the chassis 1, which is convenient for the operation and maintenance of the monitoring device. A latch structure 3 is arranged at the edge of the second flip cover 10. When it is necessary to reduce the occupied space of the chassis 1, the second flip cover 10 can be closed and fixed to the side opening of the chassis 1 by the latch structure 3. Furthermore, a hook lock 11 is arranged at the adjacent edge position when the first flip cover 6 and the second flip cover 10 are in the closed state. When the monitoring device is in a stopped state, the imaging component is stored and the first flip cover 6 can be locked by the hook lock 11. When the monitoring device needs to be operated, the hook lock 11 can be unlocked to unlock the first flip cover 6 and then extend the imaging component.

[0035] Preferably, the chassis 1 is provided with a cabinet door 13 on the side of the second chamber, and the cabinet door 13 facilitates the assembly and maintenance of the electrical equipment inside the second chamber. At the same time, when the cabinet door 13 is closed, the interior of the second chamber constructed by the side wall of the chassis 1, the cabinet door 13 and the partition is relatively closed, which can effectively prevent dust in the external environment from entering the second chamber and causing damage to the electrical equipment therein.

[0036] The central control module 12 further includes a video recording device, which is used to store the image data captured by the camera 7 and can be used for subsequent historical query and archiving.

[0037] Preferably, an antenna device 9 is also provided in the first chamber, and the antenna device 9 is electrically connected to the central control module 12, and is used to realize the data connectivity function between the central control module 12 and the remote management platform, including the remote management platform retrieving real-time video and video data, remote alarm reminders, remote control of electrical equipment opening and closing and other functions, wherein the antenna device 9 further includes the use of Ethernet, WIFI, 4G / 5G and other methods to realize data transmission function.

[0038] Preferably, a switching power supply and a leakage protector are also provided in the second chamber, and the switching power supply and the leakage protector are electrically connected to the camera 7 and the central control module 12 respectively, and are used to supply power to the camera 7, the central control module 12 and the antenna device 9 and provide leakage protection function.

[0039] In summary, the present embodiment provides a mobile on-site monitoring device for hot work operations. The monitoring device itself has good flexibility and stability, is easy to transport, and is suitable for realizing monitoring functions in various complex environments. The imaging component of the monitoring device can realize the height adjustment of the camera 7 through structural improvement. By setting a higher monitoring angle of view, the monitoring range and monitoring accuracy can be improved. The height adjustment method of the imaging component is simple and portable. When in the storage state, the overall volume occupied by the chassis 1 remains small. At the same time, in the present embodiment, the monitoring device is further provided with a central control module 12, which can receive the image data captured by the camera 7 in real time and automatically judge the image information, supervise the construction personnel not to perform hot work operations during ordinary construction operations, ensure that at least two people are on duty during hot work operations, and ensure that there are no fire sources or fire hazards on site after the hot work operations, thereby reducing the blind spots in the supervision, inspection and management of hot work operations. When an abnormal situation occurs, an alarm can be issued in time, which is conducive to the formation of efficient and intelligent supervision of hot work operations.
