[0007] By adopting the above technical solution, the flexible adjustment of the underwater monitoring range of the monitoring unit is achieved through the rotation connection design of the mounting base and the mounting shell. The power storage unit in the mounting shell provides power support for the monitoring unit to ensure long-term stable operation. The design of the transparent shell not only protects the monitoring unit from the influence of the underwater environment, but also ensures the clarity of the monitoring field of view. The setting of the drive assembly enables the mounting shell to be automatically or manually controlled to rotate, thereby adjusting the monitoring angle. The design of the mounting ring and the cleaning bristles realizes the automatic cleaning function of the outer wall of the transparent shell, effectively reducing the possibility of blurred vision caused by underwater biological attachment or dirt accumulation, which is conducive to improving the monitoring effect.

This design improves the automation of the monitoring device and facilitates remote control and intelligent management.

[0010] Optionally, the bearing portion includes a connecting bar, a connecting shaft and a connecting belt; The connecting strip is arranged on the mounting ring, and the connecting strip is formed with connecting holes located near the mounting ring, and the connecting holes are symmetrically arranged; The connecting shaft rotates on the connecting strip, the connecting shaft is located in the connecting hole and corresponds to the connecting hole one by one, the connecting belt is connected to the first position and sleeved on the connecting shaft, and the inner peripheral side wall of the connecting belt slides on the inner concave side wall and the outer convex side wall of the connecting strip; There are a plurality of cleaning bristles which are evenly arranged on the outer wall of the connecting strip, and the connecting strip is provided with a guide member for guiding the connecting strip to slide on the concave side wall of the connecting strip; The mounting ring is provided with a transmission assembly, and when the mounting shell rotates, the transmission assembly drives the connecting shaft to rotate.

[0011] By adopting the above technical solution, the bearing part includes a connecting strip, a connecting shaft and a connecting belt. This design enables the cleaning bristles to automatically clean the outer wall of the transparent shell as the connecting belt moves, thereby improving the cleaning efficiency and effect.

[0012] Optionally, a plurality of sliding blocks are evenly spaced apart on the outer convex side wall of the connecting strip, and a curved surface structure is formed on a side of the sliding block away from the connecting strip.

[0013] By adopting the above technical solution, multiple sliders are arranged on the convex side wall of the connecting strip, and the sliders are given a curved surface structure, which further improves the smoothness of the sliding of the connecting belt. The design of the slider reduces the friction resistance between the connecting belt and the connecting strip, making the cleaning process smoother and more efficient. At the same time, the design of the curved surface structure also increases the wear resistance of the slider and prolongs the service life of the overall structure.

[0014] Optionally, the guide member is a guide block, so the guide block is in a "T"-shaped structure; The guide block is arranged on the concave side wall of the connecting strip. There are a plurality of guide blocks which are evenly spaced along the extension track. The inner peripheral side wall of the connecting strip is formed with a guide groove for the guide block to slide.

[0015] By adopting the above technical solution, the specific form of the guide member is a guide block of a "T"-shaped structure, and the guide block slides in the guide groove. This design allows the connecting belt to be more stably guided and supported during the sliding process, reducing the possibility of reduced cleaning effect or equipment damage caused by unstable sliding.

[0017] By adopting the above technical solution, the transmission assembly includes a transmission shaft, a connecting bevel gear, a transmission bevel gear, a transmission gear and a transmission rack. This design realizes the function of driving the connecting shaft to rotate through the transmission assembly when the mounting shell rotates, thereby driving the cleaning bristles to clean the outer wall of the transparent shell. The precise matching and efficient transmission of the transmission assembly ensure the stability and reliability of the cleaning process, and improve the cleaning efficiency and effect.

[0018] Optionally, a monitoring lens is provided on the side wall of the monitoring part, the bottom of the mounting seat slides up and down and is symmetrically provided with push columns, and the mounting seat is provided with an elastic driving member; A push block adjacent to the mounting seat is symmetrically arranged on the outer circumference of the mounting shell, the push block has a sliding surface on the side facing the mounting seat, the push block is inclined to form a guide surface for guiding the push column to slide to the sliding surface, and the push block is inclined to form a push surface on the side away from the guide surface; When the push column slides from the guide surface to the sliding surface, the push column slides into the mounting seat; When the monitoring lens is facing the concave side wall of the connecting strip, the pushing column slides to a position where the pushing surface is close to the sliding surface. At this time, the elastic driving member drives the pushing column to slide on the pushing surface, and drives the mounting shell to rotate until the monitoring lens is misaligned with the connecting strip.

[0019] By adopting the above technical solution, the mounting seat is provided with a push column, an elastic driving member and other structures. These designs enable the monitoring device to automatically adjust the rotation angle of the mounting shell under certain conditions (such as when the monitoring lens is facing the concave side wall of the connecting strip), reducing the possibility of the monitoring field of view being blocked. The cooperation of the push column, the push block and the elastic driving member realizes this automatic adjustment function, and improves the intelligence level and adaptability of the monitoring device.

[0020] Optionally, the elastic driving member includes a driving spring, and the driving spring is installed in the mounting seat, and the driving spring pushes the driving column to protrude out of the mounting seat.

[0021] By adopting the above technical solution, the installation of the driving spring enables the push column to automatically protrude out of the mounting seat when not acted upon by external forces, thereby maintaining continuous pressure on the push block. When the monitoring lens is facing the concave side wall of the connecting strip, the push column slides to a specific position under the action of the guide surface and the push surface. At this time, the elastic force of the driving spring drives the push column to continue sliding on the push surface, thereby driving the mounting shell to rotate to a position where the monitoring lens and the connecting strip are misaligned. This design not only realizes the automatic adjustment function of the monitoring field of view, but also improves the adaptive ability and stability of the monitoring device.

The bearing part includes a connecting strip, a connecting shaft and a connecting belt. This design enables the cleaning bristles to automatically clean the outer wall of the transparent shell as the connecting belt moves, thereby improving the cleaning efficiency and effect.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-5 This application is described in further detail.

[0026] The embodiment of the present application discloses an underwater monitoring device.

[0027] See also Figure 1 and Figure 2 The underwater monitoring device comprises a mounting base 1, a mounting shell 2, a monitoring unit 22, a power storage unit 21, a transparent shell 3 and a driving assembly 4. The mounting base 1 is the cornerstone of the entire device and is stably installed in an underwater environment.

[0028] The mounting shell 2 is a cylindrical structure, and the mounting shell 2 is rotatably connected to the mounting seat 1. A mounting groove is formed in the mounting shell 2, and the notch of the mounting groove is located at the bottom of the mounting shell 2. The monitoring unit 22 and the power storage unit 21 are installed in the mounting shell 2 and located in the mounting groove. The power storage unit 21 is located above the monitoring unit 22. The monitoring unit 22 and the power storage unit 21 are electrically connected, and the power storage unit 21 provides energy to the monitoring unit 22.

[0029] The monitoring part 22 is provided with a monitoring lens 221 on the side wall. The monitoring lens 221 protrudes out of the mounting groove. When in use, the monitoring lens 221 forms a monitoring field of view in the horizontal direction to monitor the underwater ecological environment. The transparent shell 3 is fixed to the side of the mounting shell 2 away from the mounting seat 1. The transparent shell 3 blocks the mounting groove and covers the monitoring part 22, which plays a role in protecting and isolating water. The transparent shell 3 is made of transparent plastic or transparent glass. The monitoring part 22 can monitor the underwater ecological environment through the transparent shell 3.

[0030] The driving assembly 4 is arranged on the mounting seat 1, and is used to drive the mounting shell 2 to rotate, so as to adjust the monitoring range of the monitoring unit 22. The driving assembly 4 includes a driving motor 41 and a controller 42. The driving motor 41 is fixedly mounted in the mounting seat 1, and the output shaft of the driving motor 41 is fixedly connected to the mounting shell 2 and coaxially arranged, and the output shaft of the driving motor 41 is rotationally connected to the mounting seat 1. The driving motor 41 can be connected to an external power source through an electric wire, or a battery can be used to provide energy for the driving motor 41. The controller 42 is fixedly mounted in the mounting seat 1, and the controller 42 is electrically connected to the driving motor 41. The controller 42 controls the start and stop of the driving motor 41, and can control the forward and reverse rotation state of the output shaft of the driving motor 41, so as to adjust the monitoring range of the monitoring unit 22.

[0031] The underwater monitoring device also includes a mounting ring 5, which is sleeved on the outer peripheral side wall of the mounting shell 2, and the mounting ring 5 is rotatably connected to the mounting shell 2. A plurality of limiting columns 51 are symmetrically fixed at the bottom of the mounting seat 1, and the limiting columns 51 extend downward. The bottoms of the limiting columns 51 are fixed to the top end surface of the mounting ring 5. When in use, the limiting columns 51 support the mounting ring 5 and limit the rotation of the mounting ring 5, ensuring that the mounting ring 5 remains relatively still when the mounting shell 2 rotates.

[0032] See also Figure 2 and Figure 3 The underwater monitoring device further includes a bearing portion 6, which includes a connecting strip 61, a connecting shaft 62, and a connecting belt 63. The connecting strip 61 extends along an arc track, so that the connecting strip 61 is a semicircular strip structure. The two ends of the connecting strip 61 are respectively fixedly connected to the bottom of the mounting ring 5, the arc-shaped concave side of the connecting strip 61 faces the outer wall of the transparent shell 3, and the middle position of the arc-shaped convex side of the connecting strip 61 is located on the side of the transparent shell 3 away from the mounting seat 1.

[0033] See also Figure 3 and Figure 4The connecting strip 61 is formed with connecting holes 611, which are two and symmetrically arranged. The connecting holes 611 are located near the mounting ring 5. The connecting shaft 62 is rotatably connected to the connecting strip 61, and the connecting shaft 62 is located in the connecting holes 611 and corresponds to each other. The connecting belt 63 is connected end to end, and the connecting belt 63 passes through the connecting hole 611 and is sleeved on the connecting shaft 62. The inner peripheral side wall of the connecting belt 63 is in sliding contact with the arcuate inner concave side wall of the connecting strip 61, and the outer peripheral side wall of the connecting belt 63 is in sliding contact with the arcuate outer convex side wall of the connecting strip 61.

[0034] The cleaning bristles 64 are fixed on the outer wall of the connecting belt 63, and there are a plurality of cleaning bristles 64 that are evenly arranged on the connecting belt 63. The mounting ring 5 is provided with a transmission assembly 7. When the mounting shell 2 rotates, the connecting shaft 62 is driven to rotate through the transmission assembly 7, thereby driving the connecting belt 63 and the cleaning bristles 64 to move together. When the mounting shell 2 rotates, the cleaning bristles 64 clean the impurities attached to the outer wall of the transparent shell 3, and at the same time, the connecting belt 63 is made to circulate through the transmission assembly 7, thereby improving the cleaning effect of the cleaning bristles 64 on the impurities attached to the outer wall of the transparent shell 3.

[0035] The transmission assembly 7 includes a transmission shaft 71, a connecting bevel gear 72, a transmission bevel gear 73, a transmission rack 74 and a transmission gear 75. One end of the connecting shaft 62 protrudes out of the connecting bar 61, and the connecting bevel gear 72 is fixed to the end of the connecting shaft 62 and is located outside the connecting bar 61. The transmission shaft 71 is rotatably mounted on the mounting ring 5, and both ends of the transmission shaft 71 protrude out of the mounting ring 5 respectively, and the transmission shaft 71 extends in the vertical direction. The transmission bevel gear 73 is fixed on the transmission shaft 71 and is located below the mounting ring 5, and the connecting bevel gear 72 is meshed with the transmission bevel gear 73. The transmission rack 74 is an annular structure, and the transmission rack 74 is fixed on the outer peripheral side wall of the mounting shell 2. The transmission gear 75 is fixed on the outer peripheral side of the transmission shaft 71, and the transmission gear 75 is located above the mounting ring 5, and the transmission rack 74 is meshed with the transmission gear 75.

[0036] When the mounting shell 2 rotates, the transmission shaft 71 can be driven to rotate through the meshing action of the transmission gear 75 and the transmission rack 74. At this time, the connecting shaft 62 is driven to rotate through the meshing action of the transmission bevel gear 73 and the connecting bevel gear 72, so that the connecting belt 63 enters a circulating motion state, driving the cleaning bristles 64 to clean the outer wall of the transparent shell 3.

[0037] The connecting strip 61 is also provided with a guide member for guiding the connecting strip 63 to slide on the concave side wall to ensure that the cleaning bristles 64 can evenly clean the outer wall of the transparent shell 3. The guide member is a guide block 613, which is fixed on the concave side wall of the connecting strip 61. The guide block 613 is in a "T"-shaped structure, and there are multiple guide blocks 613 that are evenly spaced along the extension track of the connecting strip 61. The inner peripheral side wall of the connecting strip 63 is a guide groove 631 in a "T"-shaped structure, and the guide block 613 slides in the guide groove 631 to guide and limit the sliding track of the connecting strip 63.

[0038] In addition, the outer convex side walls of the connecting strip 61 are respectively fixedly connected with sliders 612, and there are multiple sliders 612 arranged at intervals. The sliders 612 are formed with an arc surface structure on the side facing the transparent shell 3, so that the sliders 612 are in a hemispherical block structure. The arc surface structure of the slider 612 is in sliding contact with the inner peripheral side wall of the connecting belt 63. This design can reduce the friction generated when the connecting belt 63 slides.

[0039] See also Figure 1 and Figure 2 A push groove 11 extending in the vertical direction is formed at the bottom of the mounting seat 1, and a push column 12 is provided on the mounting seat 1. The push column 12 slides up and down in the push groove 11. A limiting block is fixedly connected to the outer wall of the push column 12, and a limiting groove is formed on the side groove wall of the push groove 11. The limiting block slides up and down in the limiting groove to limit the push column 12 from leaving the push groove 11.

[0040] The mounting seat 1 is provided with an elastic driving member, which includes a driving spring 24, and the driving spring 24 is installed in the pushing groove 11. The bottom of the driving spring 24 abuts against the top of the pushing column 12, and the top of the driving spring 24 abuts against the groove wall of the pushing groove 11 away from the groove. When the driving spring 24 is elastically released, the pushing column 12 is pushed to protrude out of the pushing groove 11.

[0041] See also Figure 5 A push block 23 is fixedly connected to the outer peripheral side of the mounting shell 2. There are two push blocks 23 and they are symmetrically arranged. The push block 23 has a side adjacent to the mounting seat 1. The side of the push block 23 facing the mounting seat 1 is a sliding surface 231, and the push column 12 slides on the sliding surface 231. The push block 23 is inclined to form a guide surface 232, and the push column 12 slides on the guide surface 232, guiding the push column 12 to slide to the sliding surface 231. When the push column 12 slides on the guide surface 232, the push block 23 pushes the push column 12 to slide into the push groove 11, and squeezes the drive spring 24.

[0042] See also Figure 4 and Figure 5The pushing block 23 is inclined away from the guide surface 232 to form a pushing surface 233. When the monitoring lens 221 is facing the concave side wall of the connecting strip 61, the pushing column 12 slides to a position where the pushing surface 233 is close to the sliding surface 231. At this time, the driving spring 24 drives the pushing column 12 to slide on the pushing surface 233, pushing the mounting shell 2 to rotate to a state where the monitoring lens 221 and the connecting strip 61 are misaligned, so that the monitoring unit 22 can maintain the state of monitoring the underwater ecological environment.

[0043] The implementation principle of an underwater monitoring device in the embodiment of the present application is: Before use, the mounting frame is installed first, and the mounting frame extends under the water surface. Then, the mounting seat 1 is fixed on the mounting frame. At this time, the monitoring unit 22 is at the bottom side of the mounting seat 1. When in use, the monitoring unit 22 monitors the underwater ecological environment. The controller 42 can control the drive motor 41 to start, drive the mounting shell 2 to rotate, and increase the monitoring range of the underwater environment by the monitoring unit 22. When the mounting shell 2 rotates, the cleaning bristles 64 clean the outer wall of the transparent shell 3, which is conducive to maintaining the clarity of the monitoring.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
