Description

Technical Field

[0001] This invention belongs to the field of marine surface photography and processing technology, and particularly relates to a self-balancing camera system that is resistant to wave interference. Background Technology

[0002] For capturing information about waves and ships at sea, buoy cameras are typically installed to capture images of the sea surface or vessels. However, these images are often affected by the undulations of the waves, resulting in image shifts, ghosting, and unevenness that make identification difficult. Therefore, how to avoid interference from waves is an urgent problem to be solved. Summary of the Invention

[0003] The purpose of this invention is to provide a self-balancing camera system that is resistant to ocean wave interference. This system can be remotely controlled, and when two metal angular momentum work together, the system can achieve stable monitoring and shooting at a set angle in complex ocean wave scenarios. This is more conducive to monitoring changes in the sea level and avoids blurring of images caused by rapid up-and-down movements.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a self-balancing camera system resistant to sea wave interference, comprising a first support, a second support, a first metal momentum wheel, a second metal momentum wheel, and a camera. The first support is conical, with both ends detachably connected to the two ends of the camera. The second support is rotatably connected to the first support and located below the first support. A plurality of inflatable airbags are fitted on the second support. Two first metal momentum wheels are provided, respectively rotatably connected to both sides of the first support and arranged in a horizontal direction. The second metal momentum wheel rotates on the second support and is arranged in a vertical direction.

[0005] In this application, the applicant drew inspiration from the two-wheeled balance of a bicycle and the way space satellites adjust their attitude. The principle behind this is the conservation of angular momentum in physics. When the angular momentum of an object changes, it will transfer torque to other objects. By applying torque in one direction, the total angular momentum of the camera system is conserved, thereby maintaining the balance of the system at a set angle and avoiding the fluctuations of the camera equipment caused by waves.

[0006] Preferably, connecting blocks are fixed at both ends of the camera, and connecting sleeves are rotatably connected to the first bracket near both ends of the camera, with the connecting sleeves and connecting blocks fixed with screws.

[0007] Preferably, a first brushless motor is connected to the outer end of the first metal momentum wheel facing the first bracket. The first brushless motor is fixed to the side of the first bracket, and the first brushless motor is connected and controlled by the PDA terminal handheld device through a wireless transmission module.

[0008] Preferably, the second bracket includes a crossbar, support rods fixed to both ends of the crossbar, fixing rods fixed on both the upper and lower sides of the support rods, and the inflatable airbag sleeved on the outside of the fixing rods.

[0009] Preferably, the upper end of the crossbar is rotatably connected to a spherical connector, and two spherical connectors are symmetrically arranged. Each spherical connector is fixedly connected to a vertical rod at the end away from the crossbar, and a sleeve shaft is slidably connected to the end of the vertical rod away from the spherical connector. The sleeve shaft is fixedly connected to the first bracket at the end away from the vertical rod.

[0010] Preferably, the second metal momentum wheel is rotatably connected to the bottom of the first bracket, and a second brushless motor is connected to the upper end of the second metal momentum wheel. The second brushless motor is fixed to the bottom of the first bracket, and the second brushless motor is connected and controlled by the PDA terminal handheld device through a wireless transmission module.

[0011] Preferably, connecting plates are welded to both sides of the crossbar, and a battery box is fixed to the bottom of the connecting plates with screws. A battery pack is placed inside the battery box and is used for overall power supply.

[0012] Preferably, a bracket is fixed at the bottom of the battery box, and a propeller shaft is rotatably connected inside the bracket. One end of the propeller shaft is connected to a drive motor, and the other end is connected to a propeller blade. The battery pack supplies power to the drive motor, which is also remotely controlled via a PDA handheld device.

[0013] The beneficial effects of this invention are: it allows for remote control, facilitating the filming of target sea areas; a first bracket is set on both sides of the camera, and a second bracket is set at the bottom of the second bracket for the camera to float; a first metal momentum wheel is set on the first bracket, and a second metal momentum wheel is set on the second bracket, which are driven to rotate at high speed by the first brushless motor and the second brushless motor respectively. When the metal momentum wheels are rotating, according to the law of conservation of angular momentum and further referring to the principle of gyroscope, when all the metal momentum wheels work together, the system can achieve stable monitoring and filming at a set angle in complex sea wave scenarios, which is more conducive to monitoring changes in sea level and avoids blurring of images caused by rapid up-and-down undulations.

[0018] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] Please also refer to Figures 1 to 3 The self-balancing camera system for resisting sea wave interference according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figure 1 As shown, the self-balancing camera system for resisting sea wave interference includes a first bracket 1, a second bracket 2, a first metal momentum wheel 3, a second metal momentum wheel 4, and a camera 5. The first bracket 1 is conical, with both ends detachably connected to the two ends of the camera 5. The second bracket 2 is rotatably connected to the first bracket 1 and is located below the first bracket 1. Several inflatable airbags 6 are fitted on the second bracket 2. There are two first metal momentum wheels 3, which are rotatably connected to both sides of the first bracket 1 and are arranged in a horizontal direction. The second metal momentum wheels 4 rotate on the second bracket 2 and are arranged in a vertical direction.

[0021] In this embodiment, a brushless motor is used to drive the metal momentum wheel to rotate, thereby achieving angular momentum balance. Furthermore, when the metal momentum wheel rotates, the entire structure tends to be balanced in the direction of its rotation axis.

[0022] Meanwhile, the camera, supported by the second bracket, can float on the sea surface using the inflatable airbags 6 on the second bracket 2 to capture images of waves and ships. The inflatable airbags 6 are arranged symmetrically to improve the overall balance of the system. Specifically, the second bracket 2 includes a crossbar 10, support rods 11 fixed at both ends of the crossbar 10, and fixing rods 12 fixed on both the upper and lower sides of the support rods 11. The inflatable airbags 6 are sleeved on the outside of the fixing rods 12.

[0023] As described above, when the device is subjected to oncoming waves, the raised base often causes the camera system to tilt upwards, resulting in the final shooting angle pointing towards the sky and making it impossible to accurately locate the changes in the surrounding waves. Therefore, a second metal momentum wheel 4 is installed. The second metal momentum wheel 4 is driven to rotate by a second brushless motor 16. When the camera 5 is placed on the sea surface, the second metal momentum wheel 4 is driven to rotate at high speed by the second brushless motor 16. Specifically, the second metal momentum wheel 4 is rotatably connected to the bottom of the first bracket 1, and the second brushless motor 16 is connected to the upper end of the second metal momentum wheel 4. The second brushless motor 16 is fixed to the bottom of the first bracket 1. Therefore, the rotation axis of the second metal momentum wheel 4 is in the vertical direction, thus keeping the first bracket 1 in a vertical and stable state when waves hit.

[0024] Furthermore, a spherical connector 13 is rotatably connected to the upper end of the crossbar 10. Two spherical connectors 13 are symmetrically arranged. Each spherical connector 13 is fixedly connected to a vertical rod 14 at the end away from the crossbar 10. A sleeve shaft 15 is slidably connected to the end of the vertical rod 14 away from the spherical connector 13. The sleeve shaft 15 is fixedly connected to the first bracket 1 at the end away from the vertical rod 14. When the first bracket 1 is kept in a vertical state, the first bracket 1 is in a rotating state. Therefore, a rotatable connection is adopted at the connection between the second bracket 2 and the first bracket 1, which is connected through the spherical connector 13. At the same time, the vertical rod 14 and the sleeve shaft 15 are kept in a telescopic state to ensure that the first bracket 1 can rotate.

[0025] Similarly, for the left and right sides of the camera 5, a first bracket 1 that rotates relative to the camera is set at both ends of the camera. A first metal momentum wheel 3 is rotatably connected to the first bracket 1. A first brushless motor 9 is connected to the outer end of the first metal momentum wheel 3 facing the first bracket 1. The first brushless motor 9 is fixed to the side of the first bracket 1. When the first brushless motor 9 drives the first metal momentum wheel 3 to rotate, the camera 5 can be kept in a stable state because the rotation axis of the first metal momentum wheel 3 is in the lateral direction.

[0026] The combination of the first metal momentum wheel 3 and the second metal momentum wheel 4 can effectively ensure that the camera 5 can capture images stably on the sea surface, avoiding the problem of image shift and blurring.

[0027] Furthermore, such as Figures 2-3 As shown, in order to facilitate the installation of the camera 5, connecting blocks 7 are fixed at both ends of the camera 5. The first bracket 1 is rotatably connected to the connecting sleeves 8 near the two ends of the camera 5, and the connecting sleeves 8 are fixed to the connecting blocks 7 with screws.

[0028] After the entire camera system is placed at sea, it is powered by a battery pack. Specifically, the battery pack is installed by welding connecting plates 17 on both sides of the crossbar 10, and fixing battery box 18 to the bottom of the connecting plates 17 with screws. The battery pack is placed inside the battery box 18.

[0029] The bottom of the battery box 18 is also fixed with a bracket 19. Inside the bracket 19, a propeller shaft 20 is rotatably connected. One end of the propeller shaft 20 is connected to a drive motor 21, and the other end is connected to a propeller blade 22. The battery pack supplies power to the drive motor 21, which is also remotely controlled via a PDA terminal handheld device.

[0030] When in use, the camera transmits data via a wireless transmission module and is remotely operated via a PDA handheld device. First, the drive motor 21 is turned on to drive the propeller blade 22 to rotate. The propeller blade 22 can be directly applied to the existing boat drive structure and can perform steering operations at the same time. After driving to the target sea area, the first brushless motor 9 and the second brushless motor 16 are controlled to rotate, thereby stabilizing the overall system during camera operation.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
