It includes industrial parks, industrial parks, logistics parks, urban industrial parks, science and technology parks, creative parks, etc.

[0003] The known authorized patent with application number: CN202222053607.9 discloses a smart park monitoring camera based on the fire protection Internet of Things, including a base, a support column and a smoke alarm, the support column is provided on the top of the base, a fixing column is provided at one end of the support column away from the base, the fixing column is connected to a rotating block in an embedded form, a support rod is provided on one side of the rotating block, a monitoring camera is provided at one end of the support rod away from the rotating block, the smoke alarm is provided on the side of the monitoring camera away from the support rod, and the smoke alarm is connected to one side of the monitoring camera through a fastener. When a fire occurs in a factory building somewhere in the park, the monitoring camera near the factory building will sound an alarm at the first time through the smoke alarm arranged on one side. Through monitoring, the staff can know the place where the fire occurs at the first time, and can carry out fire fighting in time at the place where the fire occurs, thereby reducing the loss of the factory buildings in the park.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: it is not convenient to protect the camera when in use. Since most monitoring equipment is used outdoors, when objects falling from high altitude collide with the camera (such as tree branches, etc.), the camera is easily damaged. Although some cameras have protective covers, it is inconvenient to buffer the impact force of falling objects. The vibration caused by the collision of falling objects is easy to affect the parts inside the camera, thereby reducing the monitoring effect and the life of the camera. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] See also Figure 1 - Figure 5 The utility model provides a smart park monitoring device based on the fire protection Internet of Things, comprising: a column rod 1, a lifting mechanism is arranged inside the column rod 1, an output end of the lifting mechanism is connected to a mounting plate 2, a camera body 3 is installed at the bottom of the mounting plate 2, wherein the camera body 3 is a smart panoramic camera;

[0028] A fire alarm mechanism is provided on the top of the mounting plate 2, and movable blocks 4 are slidably connected on both sides of the mounting plate 2, and the bottom of the movable block 4 is threadedly connected with a hand-tightened bolt 5 that conflicts with the mounting plate 2;

[0029] A piston cylinder 6 is symmetrically fixedly mounted on the top of the movable block 4, a damping exhaust hole 7 is opened on one side of the surface of the bottom end of the piston cylinder 6, and a spring 8 is fixedly mounted on the inner bottom wall of the piston cylinder 6;

[0030] The top of the spring 8 is fixedly connected to a piston block 9 that fits the inner wall of the piston cylinder 6, the top of the piston block 9 is fixedly installed with a support rod 10 that slides with the piston cylinder 6, and the top of the support rod 10 is fixedly connected to a protective plate 11.

[0031] When in use, the park is monitored through the camera body 3, and the fire alarm mechanism can be used to alarm in the event of a fire, which is convenient for people to leave the danger zone. At the same time, the height position of the camera body 3 can be adjusted through the lifting mechanism, which is convenient for later maintenance. During the monitoring process, the top of the camera body 3 can be protected by setting a protective plate 11 to prevent falling objects from colliding with the camera body 3. When the falling objects collide with the protective plate 11, the impact force of the falling objects drives the protective plate 11 to move downward, so that the support rod 10 drives the piston block 9 to move downward to compress the spring 8. 8 applies a reaction force to the piston block 9, which can buffer the impact force. At the same time, when the piston block 9 moves downward, it can squeeze the gas in the piston cylinder 6 and discharge the gas through the damping exhaust hole 7. Since the aperture of the damping exhaust hole 7 is small, the gas is discharged slowly, which can damp the downward speed of the piston block 9 and achieve the purpose of buffering the impact force again. Therefore, the effect of buffering and protecting the camera body 3 is achieved, preventing the camera body 3 and its parts from being damaged by falling objects, and effectively improving the monitoring effect and service life of the camera body 3.

[0033] Specifically, during the monitoring process, the smoke sensor 12 can be used to monitor the fire in the park. When a fire occurs, the smoke sensor 12 detects the smoke and feeds the information back to the main control box 14. The main control box 14 controls the alarm 13 to sound an alarm. At the same time, the main control box 14 controls the camera body 3 to adjust the angle so that it can collect images of the fire scene. The information is then transmitted to the park management platform for monitoring personnel to watch, so as to understand the situation on the scene and evacuate people from the danger zone, thereby achieving the purpose of fire alarm.

The output end of the motor 24 extends into the column rod 1, and a heat dissipation hole is opened on the inner bottom wall of the mounting box.

[0036] Specifically, the bevel gear 25 is driven to rotate by the motor 24, and the bevel gear 1 23 meshing with it is driven to rotate, thereby driving the screw 20 to rotate, so that the moving block 21 drives the supporting guide rod 22 to move up and down, and then drives the mounting plate 2 to rise and fall, so as to achieve the purpose of lifting and lowering the camera body 3, which is convenient for lowering the height of the camera body 3 and facilitating subsequent maintenance by personnel.
