[0002] In order to protect the marine ecological environment and marine fishery resources, achieve sustainable development, and meet people's demand for various high-quality seafood, marine ranches came into being.

During the production process of artificial fisheries, in order to fully understand the situation of the fisheries, regular inspections are required.

[0028] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] In the present invention, by means of the angle adjustment mechanism, the driving motor can be started to drive the rotating cap to rotate, and at this time, the supporting assembly can be driven to move, so that the shooting directions of the two cameras can be adjusted, so that when shooting the fishing environment, the shooting range can be expanded;

At this time, when the sealing plate moves upward along the inner wall of the buoyancy box, the amount of seawater that can enter the buoyancy box will increase, so that the draft of the buoyancy box will be deepened, and the height of the two cameras can be lowered. When the sealing plate moves downward along the buoyancy box, the water in the buoyancy box can be discharged to the outside, reducing the draft of the buoyancy box, thereby raising the height of the two cameras upward, so that when the camera is used to shoot the picture of the fishing ground, the height of the camera can be conveniently adjusted;

[0032] In the present invention, by means of the connection mechanism, the support spring can be used to elastically support the connection rod, so that after the rotating ring is respectively connected to the plurality of fixing mechanisms, when the height of the camera is finely adjusted, a margin of activity can be provided, and when the rotating ring and the connection plate are rotationally connected, the plurality of fixing mechanisms can be prevented from being entangled;

[0033] In the present invention, by means of the fixing mechanism, after the mounting frame is mounted on the seabed, the length of the traction rope can be adjusted according to the height of the sea surface, and the rotating ring can be towed by the traction rope, so that the entire device can be in a relatively stable position on the sea surface, and after the length of the traction rope is adjusted, the two limit assemblies can be driven at the same time to drive the two arc-shaped racks to mesh with the positioning gear, so that the positioning gear can be braked, thereby the reel can be braked, and the length of the traction rope can be limited;

[0034] The present invention utilizes the buoyancy principle to adjust the height of the camera and stably support it, so that when used for security monitoring in a fishery, the purpose of real-time monitoring can be achieved. In addition, during the monitoring process, the device can rotate and adjust the camera, so that when monitoring the fishery, the shooting range can be increased, so it is convenient for use in the fishery.

[0048] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0049] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0050] Reference Figure 1-Figure 11 A multi-angle monitoring security device of this embodiment includes a support ring 1, a cross 2, a mounting tube 3, an angle adjustment mechanism, a buoyancy adjustment mechanism, a connecting mechanism and a plurality of fixing mechanisms.

[0051] First, a cross 2 is fixedly installed at the inner center position of the support ring 1, and a mounting tube 3 is fixedly connected to the top of the cross 2. The mounting tube 3 is vertically arranged and is used to install the subsequent angle adjustment mechanism.

[0052] A partition 15 is fixedly installed inside the mounting tube 3 , a driving motor 16 is fixedly installed on the top of the partition 15 , an output shaft of the driving motor 16 passes through the partition 15 and extends upward, and finally a rotating cap 5 is fixedly installed.

[0053] The bottom of the rotating cap 5 is connected to the first limiting ring 4 through a rotating connection such as a bearing, and the first limiting ring 4 is fixedly sleeved on the outer wall of the mounting tube 3 to ensure that the rotating cap 5 can rotate freely around the central axis of the mounting tube 3.

[0054] A connecting plate 6 is fixedly mounted on the top of one side of the rotating cap 5, and a mounting cover 7 is fixedly mounted on the other side of the connecting plate 6. A transparent baffle 9 is arranged at the opening of the mounting cover 7 to close the mounting cover 7 and protect the internal equipment. Two cameras 8 are symmetrically mounted on the inner wall of one side of the mounting cover 7.

[0055] Two mounting rods 10 are symmetrically fixedly installed at the bottom of the mounting cover 7, and the bottom ends of the two mounting rods 10 are connected to a slide rail 12. A slip ring 11 is fixedly installed on the top of the support ring 1, and the slide rail 12 is slidably connected to the slip ring 11 to ensure that the mounting cover 7 can remain stable while rotating.

[0056] When the driving motor 16 is started, its output shaft drives the rotating cap 5 to rotate around the central axis of the mounting tube 3. Since the connecting plate 6 is fixedly connected to the rotating cap 5, the mounting cover 7 and the camera 8 mounted thereon will also rotate accordingly. By adjusting the rotation direction and angle of the driving motor 16, the shooting direction of the camera 8 can be adjusted, thereby expanding the shooting range and covering multiple directions of the fishing ground.

[0057] At the same time, since the mounting cover 7 is slidably connected to the slip ring 11 via the slide rail 12, this structure not only provides stable support for the camera 8, but also allows the camera 8 to remain stable during rotation, thereby ensuring the clarity and stability of the captured image.

[0058] Below the support ring 1, a plurality of pontoons 14 are arranged at equal intervals, and two support rods 13 are symmetrically fixedly installed on the top of each pontoon 14. The top ends of the two support rods 13 are fixedly connected to the bottom of the cross 2, thereby ensuring that the pontoons 14 can stably support the entire device.

[0059] Inside each buoyancy box 14, a sealing plate 17 is tightly slidably connected, and a transmission rod 22 is fixedly installed on the top of the sealing plate 17. The top end of the transmission rod 22 passes through the top of the buoyancy box 14 and extends above it.

[0060] At the top of the cross 2, a stepper motor 18 is fixedly installed. The stepper motor 18 is located in the mounting tube 3. The output shaft of the stepper motor 18 extends downward, and a screw 19 is fixedly installed. The bottom end of the screw 19 is connected to the first mounting plate 23 through a rotating connecting member such as a bearing. The first mounting plate 23 is fixedly connected to multiple buoyancy boxes 14 to ensure that the screw 19 can stably drive the components in the buoyancy boxes 14.

[0061] A moving frame 21 is fixedly installed at the top of the multiple transmission rods 22, and a nut 20 is fixedly installed on the top of the moving frame 21. The nut 20 is threadedly connected to the screw 19, so that when the stepping motor 18 drives the screw 19 to rotate, the moving frame 21 and the multiple transmission rods 22 can be driven to move longitudinally through threaded transmission.

[0062] When the height of the camera 8 needs to be lowered, the stepper motor 18 is started to drive the screw 19 to rotate clockwise (assuming that clockwise rotation is the descending direction). At this time, the movable frame 21 and multiple transmission rods 22 will move downward, thereby pushing the sealing plates 17 in each pontoon 14 to move upward. As the sealing plates 17 rise, the space in the pontoon 14 increases, and seawater enters through the opening of the pontoon 14, increasing the draft depth of the pontoon 14, thereby lowering the height of the camera 8.

[0063] On the contrary, when the height of the camera 8 needs to be raised, the stepper motor 18 drives the screw 19 to rotate counterclockwise, the movable frame 21 and the transmission rod 22 move upward, and the sealing plate 17 is pulled downward to discharge part of the seawater in the buoyancy box 14, reduce the draft depth, and thus raise the height of the camera 8.

[0064] On the top inner wall of one side of each buoyancy box 14, a ventilation pipe 24 is fixedly installed, the top end of the ventilation pipe 24 extends to the top of the mounting cover 7, and a support cover 25 is fixedly installed, a retaining ring 26 and two positioning plates 28 are arranged in the support cover 25, a limiting rod 29 is fixedly installed on the positioning plate 28, a movable plate 27 and two second limiting rings 30 are slidably mounted on the limiting rod 29, and a compression spring 31 is installed between the second limiting rings 30.

[0065] When the sealing plate 17 moves, the change in air pressure in the float box 14 will push or pull the movable plate 27 to slide on the limit rod 29, thereby controlling the ventilation state of the support cover 25, ensuring the balance of air pressure inside and outside the float box 14, and avoiding excessive air pressure affecting the movement of the sealing plate 17. At the same time, the action of the compression spring 31 enables the movable plate 27 to automatically reset when the sealing plate 17 is not adjusted, thereby maintaining the sealing state of the support cover 25.

[0066] The connection mechanism includes a second mounting plate 32 fixedly connected to a plurality of buoyancy boxes 14, and a connecting rod 33 is slidably connected to the second mounting plate 32. A connecting plate 34 is fixedly installed at the bottom end of the connecting rod 33, and a rotating ring 35 is rotatably sleeved on the connecting plate 34. Multiple fixing mechanisms are connected to the bottom of the rotating ring 35 as described in detail later.

[0067] A support spring 36 is sleeved on the connecting rod 33 and is located above the second mounting plate 32. The top and bottom ends of the support spring 36 are fixedly connected to the top of the connecting rod 33 and the top of the second mounting plate 32 respectively. In this way, the elasticity of the support spring 36 can be used to elastically support the connecting rod 33, so that after the rotating ring 35 is connected to multiple fixing mechanisms, it is possible to provide room for movement when fine-tuning the camera height. At the same time, the rotating connection design between the rotating ring 35 and the connecting disk 34 can effectively prevent multiple fixing mechanisms from being entangled.

[0068] In order to ensure that the whole device is in a relatively stable position on the sea surface and to achieve accurate adjustment and fixation of the length of the towing rope, the fixing mechanism is designed as follows:

[0069] The fixing mechanism includes a connecting ring 37 fixedly mounted on the bottom of the rotating ring 35, and a traction rope 38 is fixedly mounted on the connecting ring 37. In addition, it also includes a mounting frame 39, the top of which is rotatably connected to a support shaft 40, and a reel 41 is fixedly sleeved on the support shaft 40, and the traction rope 38 is fixedly wound around the reel 41. A positioning gear 42 located below the reel 41 is also fixedly sleeved on the support shaft 40.

[0070] Two limit assemblies are symmetrically installed on the mounting frame 39, each of which is connected to an arc-shaped rack 45, and the two arc-shaped racks 45 are movably engaged with the positioning gear 42. During installation, the mounting frame 39 is installed on the seabed, and the length of the traction rope 38 is adjusted by rotating the reel 41 to adapt to changes in the sea level. After the adjustment is completed, the two limit assemblies are driven at the same time to make the two arc-shaped racks 45 engage with the positioning gear 42, thereby achieving braking of the positioning gear 42, and further braking the reel 41 to achieve the purpose of limiting the length of the traction rope 38.

[0071] In order to ensure that the arc-shaped rack 45 and the positioning gear 42 can maintain stable meshing after the adjustment is completed, the limit assembly is designed as follows:

[0072] The limiting assembly includes two L-shaped plates 43 symmetrically fixedly mounted on the top of the mounting frame 39, and the same adjustment plate 44 is slidably connected to the two L-shaped plates 43, and the adjustment plate 44 is fixedly connected to the corresponding arc-shaped rack 45. In addition, the same fixing frame 46 is also fixedly mounted on the top of the two L-shaped plates 43.

[0073] A plug rod 47 is slidably connected to the top inner wall of the fixing frame 46, and a slot is provided on the top of the adjusting plate 44. After the adjusting plate 44 is pushed to make the arc-shaped rack 45 mesh with the positioning gear 42, the plug rod 47 corresponds to the slot. At this time, the tension spring 48 sleeved on the plug rod 47 and located above the fixing frame 46 is in a stressed state, which can pull the plug rod 47 to move downward and insert the plug rod 47 into the slot, thereby limiting the adjusting plate 44 and ensuring that the arc-shaped rack 45 and the positioning gear 42 maintain a stable meshing state.

[0074] Through the above-mentioned specific implementation methods, the multi-angle monitoring security device can achieve precise adjustment and fixation of the camera height, while ensuring the stability of the entire device on the sea surface.

[0075] The present invention provides a method for using a multi-angle monitoring security device, comprising the following steps:

[0076] S1. After the mounting frame 39 is installed on the seabed, the device can use the buoyancy provided by the multiple buoyancy boxes 14 to stably support the camera 8;

[0077] S2. Adjust the length of the traction rope 38 according to the height of the sea surface, and use the traction rope 38 to pull the rotating ring 35 so that the entire device can be in a relatively stable position on the sea surface. After the length of the traction rope 38 is adjusted, the adjustment plate 44 can be pushed to drive the arc-shaped rack 45 to move, so that the arc-shaped rack 45 is meshed with the positioning gear 42, so that the support shaft 40 can be braked. At this time, the insertion rod 47 can correspond to the slot, so the tension spring 48 in a stressed state can pull the insertion rod 47 downward and insert the insertion rod 47 into the slot, so that the adjustment plate 44 can be limited, so that the arc-shaped rack 45 and the positioning gear 42 maintain stable meshing. By pulling the rotating ring 35 with multiple traction ropes 38, the device can be stably set on the sea surface;

[0078] S3. During the shooting process, the driving motor 16 can be started to drive the rotating cap 5 to rotate. When the connecting plate 6 rotates with the rotating cap 5, the mounting cover 7 can be driven to rotate and adjust around the central axis of the rotating cap 5, so that the camera 8 can be used to conveniently shoot pictures of different directions of the fishing ground;

[0079] S4, when the stepper motor 18 is started to drive the screw 19 to rotate, the movable frame 21 can be driven to move longitudinally under the action of the threaded transmission of the nut 20, thereby driving multiple transmission rods 22 to move longitudinally, so as to be able to adjust the position of the sealing plate 17 in the corresponding pontoon 14. At this time, when the sealing plate 17 moves upward along the inner wall of the pontoon 14, the amount of seawater that can enter the pontoon 14 will increase, so that the draft of the pontoon 14 will be deepened, and the height of the two cameras 8 can be lowered. When the sealing plate 17 moves downward along the pontoon 14, the water in the pontoon 14 can be discharged to the outside, reducing the draft of the pontoon 14, so that the height of the two cameras 8 can be lifted upward, so that when the camera 8 is used to shoot the picture of the fishing ground, the height of the camera 8 can be conveniently adjusted;

[0080] S5. When the sealing plate 17 moves upward in the buoyancy box 14, the gas located above the sealing plate 17 can enter the support cover 25 through the ventilation pipe 24. Under the action of the air pressure, the movable plate 27 can be pushed to move upward, so that the retaining ring 26 is in a ventilated state, so that the gas in the buoyancy box 14 can be discharged, so that the air pressure in the buoyancy box 14 is prevented from being too high and causing the sealing plate 17 to be unable to move upward. When the sealing plate 17 moves downward, the air pressure in the buoyancy box 14 will be reduced. At this time, the air pressure in the support cover 25 will be reduced synchronously, and the movable plate 27 will move downward, and the retaining ring 26 will be in a ventilated state. The ring 26 is out of contact, so the external gas can be transported to the float 14 through the support cover 25 and the vent pipe 24, so as to increase the buoyancy of the float 14, and when the movable plate 27 moves upward or downward, the compression spring 31 in the same direction can be compressed. Therefore, when the position of the sealing plate 17 is not adjusted, the compression spring 31 in a stressed state can drive the movable plate 27 to reset through the corresponding second limit ring 30, so as to continuously block the support cover 25 and prevent seawater from entering the float 14 through the support cover 25 and the vent pipe 24.
