[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Example 1, please refer to Figures 1-4The present embodiment provides an angle-adjustable security monitoring device, comprising a mounting base 1; a mounting shaft 2, the mounting shaft 2 being rotatably connected to the inner side of the mounting base 1; a connecting base 3, the connecting base 3 being fixedly sleeved on the outer wall of the mounting shaft 2; a monitoring camera 4, the monitoring camera 4 being fixedly mounted on the upper end of the connecting base 3; an air bag 51 being fixedly connected to the inner side of the mounting base 1, and providing a mechanism for delivering dry air through compression and expansion, one side of the air bag 51 being fixedly connected to a connecting hose 52, the other end of the connecting hose 52 being fixedly connected to an air intake pipe 53, the other end of the air intake pipe 53 being fixedly connected to a drying box 54, the drying box 54 being used to absorb moisture and filter air to ensure that the air entering the air bag 51 is dry, and the air inlet of the drying box 54 being fixedly connected to an air intake hood 55 The upper end of the air intake pipe 53 is connected with a delivery hose 56, and the top of the delivery hose 56 is connected with the surveillance camera 4. A one-way valve is provided at the connection between the air intake pipe 53 and the drying box 54 and the inside of the delivery hose 56. The one-way valve inside the air intake pipe 53 allows air to enter the air intake pipe 53 only from the outside, so that the delivery hose 56 can only deliver air to the inside of the surveillance camera 4. A fixed plate 514 is fixedly connected to the inner side of the mounting base 1, and the outer wall of the fixed plate 514 is rotatably connected to the rotating shaft 57. The outer wall of the rotating shaft 57 is fixedly sleeved with a movable plate 58, and connecting plates 59 are fixedly connected on both sides of the movable plate 58. The side of the connecting plate 59 is fixedly connected to a cross bar 510, and the bottom of the movable plate 58 is fixedly connected to a connecting rod 511, and the bottom of the connecting rod 511 is hinged with a pressure plate 512. A torsion spring 513 is mounted on the outer wall of the rotating shaft 57. The two ends of the torsion spring 513 are fixedly connected to the fixed plate 514 and the movable plate 58, respectively. The torsion spring 513 uses its rebound force to restore the movable plate 58, ensuring the device's self-recovery function after use. A fixed block 515 is fixedly connected to the inner side of the mounting base 1, and the air intake pipe 53 is fixedly connected to the upper end of the mounting base 1 via the fixed block 515. A protective housing 6 is fixedly connected to the outer wall of the surveillance camera 4. A heat sink 9 is fixedly mounted on the rear end of the surveillance camera 4. The heat sink 9 is used to dissipate heat from the surveillance camera 4 to prevent performance degradation or damage to the camera due to excessive temperatures. The upper end of the protective housing 6 is equipped with a cleaning component 7 and a rainproof component 8.

[0026] When in use, a motor needs to be installed on the side of the mounting seat 1, and the output end of the motor is fixedly connected to the mounting shaft 2, so that the mounting shaft 2 can be driven to rotate by the motor and then the connecting seat 3 can be driven to rotate, and finally the monitoring camera 4 can be driven to rotate, thereby changing the tilt angle of the monitoring camera 4. At the same time, when the humidity is heavy, the inside of the monitoring camera 4 can be kept dry by tilting the monitoring camera 4. When the monitoring camera 4 is tilted, it will squeeze the cross bar 510, and then the cross bar 510 will squeeze one side of the movable plate 58 through the connecting rod 511, thereby making the movable plate 58 and the rotating shaft 57 rotate, and then the connecting rod 511 at the bottom of the side of the movable plate 58 tilted downward will drop accordingly, and then the pressure plate 512 at the bottom of the connecting rod 511 will drop accordingly, and then the pressure plate 512 will squeeze the airbag 51 downward, thereby drying the inside of the airbag 51. The air will enter the interior of the air intake pipe 53 through the connecting hose 52. Since a one-way valve is provided at the connection between the air intake pipe 53 and the drying box 54, gas is only allowed to flow from the drying box 54 into the interior of the air intake pipe 53. Then, the gas from the airbag 51 entering the interior of the air intake pipe 53 can only enter the interior of the monitoring camera 4 from the delivery hose 56, thereby replacing the moisture in the monitoring camera 4 and ensuring its internal dryness. When the monitoring camera 4 is reset to a horizontal state, the airbag 51 will restore its shape after being released from the compressed state. At this time, the air can be absorbed into the drying box 54 through the suction hood 55, and then enter the interior of the air intake pipe 53 and the airbag 51 after being dried by the drying box 54. This design can infuse dry air into the interior of the monitoring camera 4 when adjusting the inclination angle of the monitoring camera 4, and can also input dry air for the monitoring camera 4 separately when needed.

[0027] Example 2, please refer to Figures 1-6 Based on Example 1, the cleaning assembly 7 includes a mounting slot 71, which is provided on the outer wall of the protective shell 6. A rotating rod 72 is rotatably connected to the inner wall of the mounting slot 71. A movable rod 73 and a scraper 74 are fixedly sleeved on the outer wall of the rotating rod 72. A sliding slot is provided at the upper end of the protective shell 6, and a slider is slidably connected inside the sliding slot. A movable plate 75 is fixedly connected to the upper end of the slider. A movable slot 76 is provided in the middle of the movable plate 75. A sliding shaft 77 is fixedly connected to the outer wall of the movable rod 73. A telescopic rod 78 is hinged to the side of the movable plate 75. The other end of the telescopic rod 78 is hinged to the protective shell 6. A fixed rod 79 and an arc plate A711 are fixedly connected to the upper end of the mounting base 1. The upper end of the fixed rod 79 is fixedly connected to the arc plate B710. A sliding rod 713 is fixedly connected to one side of the movable plate 75. The sliding shaft 77 is slidably connected to the inside of the movable slot 76, and a spring 712 is movably sleeved on the outer wall of the telescopic rod 78.

[0028] When the front end of the monitoring camera 4 is tilted downward, the sliding bar 713 on the side of the movable plate 75 at its upper end will rotate with the monitoring camera 4. At the same time, the end of the sliding bar 713 away from the movable plate 75 will slide on the outer wall of the curved plate A711, and the distal end of the curved plate A711 gradually widens, so the sliding bar 713 will rotate and gradually drive the movable plate 75 away from the curved plate A711. When the movable plate 75 moves, the position of the movable groove 76 opened on the outside will also change accordingly, and the sliding shaft 77 will slide inside the movable groove 76. When the movable plate 75 slides a certain distance, the sliding shaft 77 will contact the inner wall of one side of the movable groove 76. At this time, the movable plate 75 continues to move, which will drive the sliding shaft 77 to move sideways. At this time, one end of the telescopic rod 78 hinged on the side of the movable plate 75 also moves to be parallel to the hinge point of the other end of the telescopic rod 78 and the protective shell 6. When the movable plate 75 continues to move, the end of the telescopic rod 78 hinged to the movable plate 75 crosses the parallel When the movable plate 75 is reset, the rear end of the monitoring camera 4 is tilted downward, and one end of the movable plate 75 contacts the curved plate B710, and the movable plate 75 is pushed toward the curved plate A711. At the same time, when the hinge point of the telescopic rod 78 and the movable plate 75 passes the hinge point at the other end, the movable plate 75 is quickly pushed back by the spring 712. After the angle of the monitoring camera 4 is tilted to a certain extent, the scraper 74 rotates rapidly to clean the monitoring camera 4, ensuring that the cleaning process is fast and quick without affecting the monitoring effect of the monitoring camera 4.

[0029] Example 3, please refer to Figure 1-Figure 7Based on Example 1, the rainproof assembly 8 includes a hydraulic chamber 81. Hydraulic rods A82 and B83 are slidably connected to the two ports of the hydraulic chamber 81. The other ends of the hydraulic rods A82 and B83 are fixedly connected to a connecting block 810 and a movable rod 84, respectively. The connecting block 810 is fixedly connected to the movable plate 75. A linkage rod A86 is hingedly connected to the rear end of the protective shell 6 via a hinge seat. One end of the movable rod 84 is hingedly connected to a linkage rod B85. The other end of the linkage rod B85 is hingedly connected to the linkage rod A86. A baffle 87 is fixedly connected to the bottom of the linkage rod A86. The outer wall of the baffle 87 is provided with vents 88. The vents 88 are staggered in position transversely with the heat dissipation holes of the heat dissipation plate 9. By providing the vents 88 and staggering them with the heat dissipation holes, the effect of the baffle 87 on the heat dissipation plate 9 is reduced when the baffle 87 is located at the front end of the heat dissipation plate 9. The rainproof effect can also be achieved when the baffle 87 covers the surface of the heat dissipation plate 9. The upper end of the protective shell 6 is fixedly connected to a slide rail 89 , and the moving rod 84 is slidably connected to the upper end of the slide rail 89 .

[0030] During use, when the movable plate 75 moves, it will drive the connecting block 810 to move, and then the connecting block 810 will drive the hydraulic rod A82 to enter the interior of the hydraulic warehouse 81, then the hydraulic rod B83 at the other end of the hydraulic warehouse 81 will move toward the outside, and then drive the movable rod 84 to slide on the outer wall of the slide rail 89, and then the movable rod 84 will drive the linkage rod A86 to rotate around this hinge point through the linkage rod B85, and then the baffle 87 at the bottom of the linkage rod A86 will cover the heat dissipation plate 9 at the rear end of the surveillance camera 4 to prevent it from entering its interior when the rain is too heavy, and then when the rain is too heavy, the adjustment effect of the surveillance camera 4 can be used to realize the rotation of the baffle 87 to achieve a waterproof effect.

[0031] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
