Description

Technical Field

[0001] The present invention relates to the technical field of cameras, and in particular to a multi-angle adjustable camera for a street lamp. Background Art

[0002] A camera, also known as a computer camera, computer eye, electronic eye, etc., is a video input device that is widely used in video conferencing, telemedicine, and real-time monitoring. Ordinary people can also use the camera to talk and communicate with each other over the Internet with images and sounds.

[0008] By adopting the above technical solution, the rain shield tube rotates with the camera when the camera rotates, thereby preventing the rain shield tube from blocking the camera's line of sight, and the provision of the rain shield tube can reduce damage to the camera caused by rainy and snowy weather.

[0009] Preferably, a circular wedge strip is fixedly connected to the upper end of the micro-control disk, the circular wedge strip extends into a circular wedge groove and is rotatably connected, and the circular wedge groove is provided on the lower end surface of the top plate.

[0010] By adopting the above technical solution, the arrangement of the circular wedge strip and the circular wedge groove enables the camera to be snapped onto the top plate and to rotate smoothly.

[0011] Preferably, a rectangular groove is opened on one side of the camera, a connecting rod is fixedly connected in the rectangular groove, and the connecting rod passes through the support plate and is rotatably connected.

[0012] By adopting the above technical solution, the connection rod is arranged in the rectangular groove to support and limit the camera.

[0013] Preferably, a bearing is fixedly connected inside the micro-control chamber, and the horizontal rod extends into the bearing and is fixedly connected.

[0014] By adopting the above technical solution, the arrangement of the bearings in the micro-control warehouse enables the horizontal rod to rotate smoothly.

[0015] Preferably, the camera and the camera port match in size.

[0016] By adopting the above technical solution, the camera port does not block the camera's sight when the camera moves in an arc with the connecting rod as the axis.

[0017] Preferably, an air chamber is opened in the micro-control disk, an air bag is arranged in the air chamber, the air bag and the air tube are fixedly connected, the air tube is fixedly connected to the bottom of the micro-control disk and faces the camera at one end away from the air bag, an elastic expansion joint is fixedly connected to the air tube, the elastic expansion joint is arranged in the air chamber, a pressure plate is arranged under the air bag, the pressure plate is arranged in the air chamber and is slidably connected, the pressure plate and the pressure rod are fixedly connected, the pressure rod extends out of a rectangular groove and is slidably connected, the rectangular groove from which the pressure rod extends is opened on the side wall of the lower end of the air chamber, and one end of the pressure rod extending out of the rectangular groove is hinged to the camera.

[0018] By adopting the above technical solution, when the camera moves in an arc with the connecting rod as the axis, the dust on the camera will partially leave the camera due to inertia. When the camera moves in an arc with the connecting rod as the axis, the pressure rod pushes the pressure plate to squeeze the airbag, so that the airbag emits a small amount of wind through the air pipe, thereby accelerating the air flow near the camera, so that more dust leaves the camera, which is practical and convenient.

[0019] Preferably, the connecting slide is annular, and two ends of the connecting slide are respectively fixedly connected to a group of brushes, and the brushes fit in the connecting slide and are slidably connected. The inner side of the rain shield pipe to which the connecting slide is fixedly connected is fixedly connected to an annular rack, and the annular rack is meshed with the gear. There are several groups of gears, and each group of gears is fixedly connected to the upper end of a group of rotating rods, and each group of rotating rods passes through a group of rotating cylinders and is fixedly connected. Each group of rotating cylinders is fixedly connected with a push plate, and each group of push plates on the rotating cylinders has two groups, and each group of push plates fits the upper surface of the chassis and is rotatably connected. A through hole is opened in the center of the chassis, and the through hole and the L hole correspond and are connected, and the corresponding and connected L holes on the through hole are opened at the upper end of the lamp pole, and a discharge port is opened in the connecting slide opened in the chassis, and several groups of the discharge ports are opened and are evenly distributed in an annular manner in the connecting slide.

[0020] By adopting the above technical scheme, when the rain shield pipe rotates following the micro-control disk, the annular rack and several groups of gears in the rain shield pipe are meshed to make the gear rotate, that is, the rotating rod on the gear drives the rotating drum fixedly connected to the rotating rod to rotate, thereby rotating the push plate, and the rotation of the push plate pushes the dust on the chassis to move, and some of the dust leaves the device through the through hole and the L hole, and some of the dust enters the connecting chute. When the rain shield pipe moves, the brush fixedly connected to the connecting slide plate at the bottom of the rain shield pipe rotates in the connecting chute, thereby driving the dust in the connecting chute to leave the device through several discharge ports opened at the bottom of the connecting chute, so that it is not easy for a lot of dust to accumulate in the connecting chute, causing the rain shield pipe to get stuck or even get stuck and unable to rotate.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] During operation, when the monitoring room receives a notification that a traffic accident has occurred near the device, the device is connected to a power source, and the power source supplies power to the slow motor and the micro-control motor respectively. The slow motor causes the micro-control disk to rotate slowly as a whole, thereby causing the camera at the bottom of the micro-control disk to rotate horizontally, thereby adjusting the direction of the camera to face the traffic accident. The micro-control motor causes the horizontal rod to rotate, that is, the reel on the horizontal rod rotates, thereby causing the elastic soft belt on the reel to slowly pull one end of the camera. Due to the limitation of the support plate on the camera, the elastic soft belt pulls the camera to move in an arc with the connecting rod as the axis, thereby aiming at the traffic accident scene, thereby making it easier for people to understand the situation at the traffic accident scene in a timely manner and take targeted measures, and also reduces the problem that the camera cannot adjust the angle when the monitoring personnel in the monitoring room view the traffic accident scene through the camera, thereby affecting the viewing of the traffic accident scene. When the camera rotates, the rain shield follows the camera to rotate, thereby preventing the rain shield from blocking the camera's line of sight, and the setting of the rain shield can reduce damage to the camera in rainy and snowy weather, which is practical and safe.

The inner side of the rain shield pipe 14 to which the connecting slide 19 is fixedly connected is fixedly connected with an annular rack 29, and the annular rack 29 is meshed with a gear 30.
