At the same time, the sleeve is driven up and down by the cross spiral groove on the reciprocating screw. The up and down movement of the sleeve pushes the push rod upward. The push rod pushes upward through the sliding groove inside the rain shield to extend the slide plate to both sides, thereby preventing the camera from being damaged by rain in rainy weather.

[0006] Preferably, the drying device includes a roller, a filter box, a rotating rod, a cross fan, and a cam. The circumferential surface of the roller contacts the front of the support column, the rotating rod is fixedly connected to the right side of the roller, the filter box is installed on the top of the movable plate, and the cross fan is fixedly connected to the circumferential surface of the rotating rod. The filter box is driven up and down by the movable plate, and the filter box drives the roller to move up and down when it moves up and down. The roller moves up and down to contact the support column, causing the roller to rotate. The rotation of the roller drives the rotating rod to rotate. The rotation of the rotating rod drives the cross fan to flip the desiccant and increase the contact area between the desiccant and the air, thereby increasing its moisture absorption capacity and preventing the desiccant from agglomerating due to moisture, thereby maintaining its effectiveness. The rotation of the rotating rod drives the cam to rotate. When the cam rotates, it rotates with the contact cross fan to stir the desiccant in the filter box, increasing the contact area between the desiccant and the air.

[0008] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. The video surveillance device for property management operates through the cooperation among a motor 1, a reciprocating screw, a sleeve, a connecting plate, a push rod, a rain shield, a slide plate, a movable plate 1, and a fixed plate 1. When the video surveillance device for property management is started, the motor 1 drives the reciprocating screw to rotate, and the cross-type spiral groove on the reciprocating screw drives the movable plate 1 to move up and down. The up and down movement of the movable plate 1 drives the fixed plate 1 to move up and down, and the up and down movement of the fixed plate 1 drives the camera to move up and down. The up and down movement of the camera enables the monitoring equipment to cover a wider area, reduce blind spots, and improve safety.

The rotation of the rotating rod drives the cross fan to flip the desiccant and increase the contact area between the desiccant and the air, thereby increasing its moisture absorption capacity and preventing the desiccant from agglomerating due to moisture, thereby maintaining its effectiveness. The rotating rod One rotation drives the cam to rotate, and when the cam rotates, it rotates with the contact cross fan, stirring the desiccant in the filter box, increasing the contact area between the desiccant and the air. When the cross fan is turned, it stirs and contacts the contact rod, causing the contact rod to move forward. The forward movement of the contact rod drives the sliding plate forward, and the forward movement of the sliding plate causes the sliding rod to move upward through its internal sliding groove. The upward movement of the sliding rod drives the brush upward to scrape off the rain marks on the camera after rain. Because the rain marks will affect the clarity of the lens, scraping them can significantly improve the quality of the monitoring picture, so that the monitoring image can better capture details and improve the accuracy of event recognition.

[0010] 3. The video surveillance device for property management works in coordination with the L-shaped plate, the cross plate, the oil barrel, the second rotating rod, the toggle plate, the top plate, the second movable plate, the spring telescopic column and the pipeline. When the video surveillance device for property management is started, the contact rod moves forward to drive the L-shaped plate to move forward. When the L-shaped plate moves forward, it contacts the cross plate, causing the cross plate to rotate. The rotation of the cross plate drives the second rotating rod to rotate. The rotation of the second rotating rod drives the toggle plate to rotate. At the same time, the torsion spring in the cross plate resets it, causing the toggle plate to swing back and forth to stir the lubricating oil in the oil barrel, ensuring that the lubricating oil is added. The agent is evenly distributed, thereby optimizing its performance and preventing the lubricant from settling during storage. Agitation can help redisperse the sediment to prevent damage to the equipment. The toggle plate moves upward with the top plate when it swings back and forth. The upward movement of the top plate drives the movable plate 2 to move up and down. The spring telescopic column is extended and retracted up and down to make the movable plate 2 move back and forth, so that the pipeline indirectly applies the lubricant evenly on the reciprocating screw to prevent it from rusting and getting stuck, so that the camera cannot move up and down to adjust the monitored angle. At the same time, oil-absorbing cotton is provided in the pipeline to prevent the lubricant from overflowing and leaking in the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS
