[0024] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0025] Please refer to Figure 1 A panoramic monitoring device for a downward field of view comprises a shell, a second camera, and at least two first camera groups relatively arranged on the circumference of the shell; each of the first camera groups comprises two first cameras arranged back to back; the angle between the plane where each first camera is located and the horizontal plane is an acute angle; the second camera is arranged at the bottom of the shell, and the second camera is rotatably connected to the shell.

[0026] From the above description, it can be seen that the beneficial effects of the utility model are: by arranging at least two first camera groups on the shell, and each first camera group includes two first cameras arranged back to back, that is, at least four first cameras are arranged to realize panoramic monitoring; and the angle between the plane where each first camera is located and the horizontal plane forms an acute angle, so that each first camera can effectively monitor the field of view below; at the same time, a second camera is also arranged at the bottom of the shell, and the second camera is rotatably connected to the shell to realize tracking of specific targets in the monitoring field of view, thereby improving the monitoring accuracy of the field of view below the panoramic monitoring device.

[0027] Furthermore, the angle between the plane where the first camera is located and the horizontal plane ranges from 22.5° to 62.5°.

[0028] From the above description, it can be seen that by setting the angle between the plane where the first camera is located and the horizontal plane to 22.5°-62.5°, while ensuring that the first camera has a larger monitoring range, it can focus on capturing the field of view below, thereby improving the monitoring accuracy of the field of view below.

[0029] Furthermore, it also includes a rotating mechanism; one end of the rotating mechanism is rotatably connected to the shell and can rotate 360° around the rotation axis of the shell; one end of the rotating mechanism away from the shell is connected to the second camera.

[0030] It can be seen from the above description that by providing a rotating mechanism, the second camera can rotate 360° relative to the rotation axis of the shell, so that a specific target within the monitoring field of view can be effectively tracked.

[0031] Furthermore, the rotating mechanism includes a horizontal rotating component; the horizontal rotating component includes a first conveyor belt, a first motor and a first rotating shaft; the first rotating shaft is parallel to the rotation axis of the shell; the first conveyor belt surrounds the first motor and the first rotating shaft, and the inner side of the first conveyor belt is respectively abutted against the transmission end of the first motor and the circumferential surface of the first rotating shaft; one end of the first rotating shaft is rotatably connected to the shell; the other end of the first rotating shaft is connected to the second camera.

[0032] From the above description, it can be seen that by forming a horizontal rotating assembly composed of a first conveyor belt, a first motor and a first rotating shaft, after the first conveyor belt is driven to rotate by the first motor, the first conveyor belt then drives the first rotating shaft to rotate, thereby effectively realizing the relative rotation of the second camera and the shell, thereby allowing the second camera to rotate 360° relative to the shell.

[0033] Furthermore, one end of the rotating mechanism away from the shell is rotatably connected to the second camera, and the rotation axis of the second camera is perpendicular to the rotation axis of the shell.

[0034] From the above description, it can be seen that by rotatably connecting the second camera to the rotating mechanism and the rotation axis of the second camera is perpendicular to the rotation axis of the shell, the second camera can rotate in the horizontal direction while also being able to rotate in the vertical direction, thereby more effectively tracking specific targets within the monitoring field of view.

[0035] Furthermore, the rotating mechanism includes a vertical rotating component; the vertical rotating component includes a second conveyor belt, a second motor and a second rotating shaft; the second rotating shaft is perpendicular to the rotation axis of the shell; the second conveyor belt surrounds the second motor and the second rotating shaft, and the inner side of the second conveyor belt is respectively in contact with the transmission end of the second motor and the circumferential surface of the second rotating shaft; the end face of the second rotating shaft is connected to the second camera.

[0036] From the above description, it can be seen that the vertical rotating assembly composed of the second conveyor belt, the second motor and the second rotating shaft can effectively realize the relative rotation of the second camera and the rotating mechanism, so that the second camera can be rotated 360° relative to the shell through the first motor, and can also rotate in the vertical direction.

[0037] Furthermore, the flip angle range of the vertical rotating component is -225°-45°.

[0038] It can be seen from the above description that the second camera can be flipped within a range of -225°-45° by means of the vertical rotation component, thereby ensuring that the second camera can track targets within the field of view.

[0039] Furthermore, a connecting piece is provided at one end of the shell away from the rotating mechanism; the connecting piece is used to be connected to the base.

[0040] It can be seen from the above description that by arranging a connecting piece at the top end of the shell, the device can be connected to the base through the connecting piece, which facilitates the installation of the device.

[0041] Furthermore, the shell is a cylindrical body.

[0042] It can be seen from the above description that by setting the shell to be cylindrical, it is possible to avoid the corners of the shell from blocking the camera.

[0043] Furthermore, it also includes two mounting parts; the two mounting parts are symmetrically arranged about the axis of the shell; and each of the mounting parts is provided with two first cameras arranged opposite to each other.

[0044] From the above description, it can be seen that by arranging two mounting parts relatively on the shell and arranging two first cameras relatively on the mounting parts, that is, the two first cameras form complementary angles and monitor relative directions respectively, thereby achieving panoramic monitoring.

[0045] The panoramic monitoring device for the downward field of view provided by the utility model can be applied to scenes such as power monitoring, and is described below through specific implementation methods:

[0052] The rotating mechanism 6 includes a horizontal rotating component 61 and a vertical rotating component 62; wherein, the horizontal rotating component 61 includes a first conveyor belt 611, a first motor 612 and a first rotating shaft 613; the first rotating shaft 613 is parallel to the rotation axis of the shell 1; the first conveyor belt 611 surrounds the first motor 612 and the first rotating shaft 613, and the inner side of the first conveyor belt 611 is respectively abutted against the transmission end of the first motor 612 and the circumferential surface of the first rotating shaft 613; one end of the first rotating shaft 613 is rotatably connected to the shell 1; the other end of the first rotating shaft 613 is connected to the second camera 2.
