Description
Technical Field
[0001] This utility model relates to the field of image transmission device technology, and in particular to a portable wireless underwater image transmission device. Background Technology
[0002] A portable wireless underwater image transmission device is a miniaturized underwater equipment that integrates image acquisition, signal processing, and wireless transmission functions. It mainly achieves real-time transmission of underwater images through underwater acoustic channels or optical communication links. It is widely used in marine scientific research, underwater rescue, pipeline inspection, and unmanned underwater vehicle scenarios. The device needs to meet the portability design to be suitable for manual carrying or small carriers, while overcoming the impact of complex underwater environments on image transmission quality. Its core function is to achieve stable end-to-end image data transmission through hardware integration and algorithm optimization.
[0003] Early underwater image transmission equipment employed a discrete hardware architecture, consisting of an underwater camera, independent source coding modules, channel coding modules, and transducers. This structure, due to the independent design of each module, could not adaptively adjust to the characteristics of the underwater channel, often resulting in the dual problems of image compression distortion and high transmission error rates. To address these shortcomings, existing equipment has gradually adopted an embedded integrated design, embedding the encoding and decoding algorithms into an ARM microprocessor and implementing end-to-end feature mapping through mutual information-optimized neural networks, effectively improving transmission robustness in low signal-to-noise ratio environments. However, existing devices still face the critical challenge of insufficient adaptability to underwater environments, and their outer shells mostly employ fixed, sealed structures. Although basic waterproofing is achieved through O-rings or sealant, it cannot automatically adapt to dynamic changes in underwater water pressure. As the equipment dives deeper, the external water pressure continues to increase. The pressure resistance of the fixed shell depends on the preset material strength. Once the design pressure threshold is exceeded, seawater will seep in through the joints or weak points, causing short circuits and damage to the internal circuitry. Although some equipment delays damage by thickening the shell or adding pressure sensor alarms, the lack of dynamic pressure compensation, i.e., the inability to automatically adjust the internal cavity volume or pressure balance mechanism according to real-time water pressure, means that the equipment is still at risk of being damaged by sea pressure in deep sea or areas with sudden changes in water pressure, which seriously limits its operating depth and environmental adaptability. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a portable wireless underwater image transmission device, which aims to improve the problem that the existing technology cannot automatically adjust the internal cavity volume or pressure balance mechanism according to real-time water pressure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable wireless underwater image transmission device, comprising a pressure-resistant shell, an adaptive pressure mechanism provided on the front right side of the pressure-resistant shell, an auxiliary installation mechanism provided on the top of the pressure-resistant shell, the auxiliary installation mechanism being used to assist in the installation of the device and a quick-install bracket, a shooting component provided on the front left side of the pressure-resistant shell, and a heat dissipation component provided on the front of the pressure-resistant shell; The adaptive pressure mechanism includes a pressure-resistant cylinder, the rear end of which is connected to the front side of the pressure-resistant housing. A bellows is provided on the inner wall of the pressure-resistant cylinder, the rear end of which is connected to the front side of the pressure-resistant housing. A sliding ring is fixedly connected to the front end of the bellows. A conical extrusion block is slidably connected to the inner wall of the sliding ring. An inclined ring is slidably connected to the rear side of the inner wall of the sliding ring. A sealing ring is fixedly connected to the outer wall of the sliding ring. A pipe cap is threadedly connected to the front end of the outer wall of the pressure-resistant cylinder. Multiple connecting holes are opened on the front side of the pipe cap.
[0006] As a further description of the above technical solution: The auxiliary installation mechanism includes an inclined pressure plate, the outer wall of which is located at the top of the inner wall of the pressure-resistant housing. A limiting plate is fixedly connected to the top of the inclined pressure plate, a rotating bar is rotatably connected to the top of the limiting plate, and a U-shaped plate is rotatably connected to the top of the rotating bar. A signal transceiver is fixedly connected to the top of the inner wall of the U-shaped plate, and a fixing screw is threaded to the front side of the inner wall of the U-shaped plate. An auxiliary component is provided on the outer wall of the U-shaped plate, and slots are provided on both the upper and lower sides of the pressure-resistant housing.
[0007] As a further description of the above technical solution: The auxiliary component includes two buffer plates, the bottom ends of which are fixedly connected to the left and right sides of the bottom of the inner wall of the U-shaped plate, respectively. The front left and right sides of the U-shaped plate are provided with strip holes.
[0008] As a further description of the above technical solution: The shooting component includes a camera, the rear end of which is fixedly connected to the front left side of the pressure-resistant housing, and the front end of which is fixedly connected to an illumination ring.
[0009] As a further description of the above technical solution: The heat dissipation assembly includes two heat dissipation ports, the outer walls of which are respectively opened on the left and right sides of the front part of the pressure-resistant housing, and multiple heat dissipation fins are fixedly connected to the inner walls of the heat dissipation ports.
[0010] As a further description of the above technical solution: A side lens is fixedly connected to the right side of the pressure-resistant housing, and the side lens is designed to withstand high pressure.
[0011] As a further description of the above technical solution: The bottom end of the limiting plate engages with the inner wall of the slot, and both the upper and lower ends of the rotating bar are designed with damping.
[0012] As a further description of the above technical solution: The rear end of the conical extrusion block has the same dimension as the front side of the inner wall of the inclined ring, and the outer wall of the sliding ring is slidably connected to the inner wall of the pressure-resistant cylinder.
[0013] This utility model has the following beneficial effects: 1. In this utility model, the pressure-resistant cylinder is sealed by a pipe cover, and the connecting hole allows seawater to enter the cylinder. When the equipment is submerged, the external water pressure acts on the front end of the sliding ring through the connecting hole, pushing it to slide backward along the inner wall of the pressure-resistant cylinder. At this time, the bellows is pulled back and its elastic reaction force is initially balanced with the external water pressure. At the same time, the inclined ring inside the sliding ring contacts the conical extrusion block. The sliding ring moves backward and pushes the conical extrusion block to move towards the pressure-resistant outer shell, further extruding the bellows. The sealing ring prevents seawater from seeping into the main body of the equipment, thereby enabling the equipment to automatically adapt to water pressure changes in deep water and avoid damage to the outer shell due to pressure difference.
[0014] 2. In this utility model, the inclined pressure plate is fixed to the top of the pressure-resistant shell, and the limiting plate restricts the swing range of the rotating bar. When installing auxiliary equipment or brackets, the rotating bar rotates around the limiting plate to adjust the angle of the U-shaped plate. The U-shaped plate is locked in position by fixing screws, thereby adjusting the orientation of the signal transceiver. After the signal transceiver is started, it transmits and receives signals through the underwater acoustic transducer or optical module. The slot allows the quick-plug bracket to be fixed to the upper and lower sides of the equipment through the buckle structure, thereby realizing multi-scenario installation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model is provided: a portable wireless underwater image transmission device, including a pressure-resistant shell 1, an adaptive pressure mechanism 2 provided on the front right side of the pressure-resistant shell 1, an auxiliary installation mechanism 3 provided on the top of the pressure-resistant shell 1, the auxiliary installation mechanism 3 is used to assist in the installation of the device and a quick-install bracket, a shooting component 4 provided on the front left side of the pressure-resistant shell 1, and a heat dissipation component 5 provided on the front of the pressure-resistant shell 1. The adaptive pressure mechanism 2 includes a pressure-resistant cylinder 21, the rear end of which is connected to the front side of the pressure-resistant outer shell 1. A bellows 22 is provided on the inner wall of the pressure-resistant cylinder 21, with its rear end connected to the front side of the pressure-resistant outer shell 1. The bellows 22 is pulled backward and compressed by a sliding ring 23, and the reaction force generated by its elastic deformation forms a preliminary balance with the external water pressure. A sliding ring 23 is fixedly connected to the front end of the bellows 22. The external water pressure acts on the front end of the sliding ring 23 through the connecting hole 28, pushing the sliding ring 23 along the pressure-resistant cylinder 21. 1. The inner wall slides backward. A conical extrusion block 24 is slidably connected to the inner wall of the sliding ring 23. An inclined ring 25 is slidably connected to the rear side of the inner wall of the sliding ring 23. A sealing ring 26 is fixedly connected to the outer wall of the sliding ring 23. The sealing ring 26 is tightly attached to the inner wall of the pressure-resistant cylinder 21 to ensure that seawater does not seep into the main body of the equipment during the sliding process. A pipe cover 27 is threadedly connected to the front end of the outer wall of the pressure-resistant cylinder 21. Multiple connecting holes 28 are opened on the front side of the pipe cover 27. The front end of the pressure-resistant cylinder 21 is closed by the pipe cover 27. The connecting holes 28 allow seawater to enter the cylinder. Specifically, the front end of the pressure-resistant cylinder 21 is sealed by the pipe cap 27, and the connecting hole 28 allows seawater to enter the cylinder. When the equipment submerges, the external water pressure acts on the front end of the sliding ring 23 through the connecting hole 28, pushing the sliding ring 23 to slide backward along the inner wall of the pressure-resistant cylinder 21. At this time, the bellows 22 is pulled backward by the sliding ring 23 and compressed. The reaction force generated by its elastic deformation forms a preliminary balance with the external water pressure. At the same time, the inclined ring 25 on the inner wall of the sliding ring 23 contacts the conical extrusion block 24. As the sliding ring 23 moves backward, the inclined ring 25 slides along the inclined surface of the conical extrusion block 24, pushing the conical extrusion block 24 to move towards the pressure-resistant outer shell 1, further extruding the bellows 22, reducing the volume of the internal cavity of the bellows 22 and increasing the internal air pressure, thereby dynamically compensating for the external water pressure. The sealing ring 26 is tightly attached to the inner wall of the pressure-resistant cylinder 21 to ensure that seawater does not seep into the main body of the equipment during the sliding process, so that the equipment can automatically adapt to water pressure changes in deep water and avoid damage to the outer shell due to pressure difference.
[0019] Reference Figure 2 , Figure 3 and Figure 5 The auxiliary installation mechanism 3 includes an inclined pressure plate 31. The outer wall of the inclined pressure plate 31 is set at the top of the inner wall of the pressure-resistant housing 1. The inclined pressure plate 31 is fixed to the top of the pressure-resistant housing 1. A limiting plate 32 is fixedly connected to the top of the inclined pressure plate 31. The limiting plate 32 limits the swing range of the rotating bar 33. The top of the limiting plate 32 is rotatably connected to the rotating bar 33. The top of the rotating bar 33 is rotatably connected to the U-shaped plate 34. A signal transceiver 35 is fixedly connected to the top of the inner wall of the U-shaped plate 34. A fixing screw 36 is threadedly connected to the front side of the inner wall of the U-shaped plate 34. The rotating bar 33 can rotate around the limiting plate 32. The angle of the U-shaped plate 34 can be adjusted to realize the orientation adjustment of the signal transceiver 35. An auxiliary component 37 is provided on the outer wall of the U-shaped plate 34. Slots 38 are provided on the upper and lower sides of the pressure-resistant housing 1. The slots 38 allow the quick-plug bracket to be fixed to the upper and lower sides of the equipment through the buckle structure. The auxiliary component 37 includes two buffer plates 371. The bottom ends of the two buffer plates 371 are fixedly connected to the bottom left and right sides of the inner wall of the U-shaped plate 34, respectively. The front left and right sides of the U-shaped plate 34 are provided with strip holes 372. When the device is hit, the buffer plates 371 absorb the impact force and protect the signal transceiver 35. The strip holes 372 are used to insert data cables or fix ropes, and can be connected to external sensors or brackets. Specifically, the inclined pressure plate 31 is fixed to the top of the pressure-resistant housing 1. The inclined angle design guides the water flow and reduces the resistance when the equipment moves. The limiting plate 32 restricts the swing range of the rotating bar 33. When auxiliary equipment or brackets need to be installed, the rotating bar 33 can rotate around the limiting plate 32 to adjust the angle of the U-shaped plate 34 and realize the orientation adjustment of the signal transceiver 35. After the signal transceiver 35 is started, it transmits and receives signals through the underwater acoustic transducer or optical module. In the auxiliary component 37 on the outer wall of the U-shaped plate 34, the buffer plate 371 is made of elastic rubber. When the equipment is hit, the buffer plate 371 absorbs the impact force and protects the signal transceiver 35. The strip hole 372 is used to insert data cables or fixing ropes and can connect external sensors or brackets. The slot 38 allows the quick-plug bracket to be fixed to the upper and lower sides of the equipment through the buckle structure to realize multi-scenario installation.
[0020] Reference Figure 1 , Figure 2 and Figure 3 The imaging component 4 includes a camera 41, the rear end of which is fixedly connected to the front left side of the pressure-resistant housing 1, and the front end of which is fixedly connected to an illumination ring 42. The camera 41 performs image acquisition in the high-pressure underwater environment. The illumination ring 42 is a circular ring surrounding the lens, and multiple LED light sources are evenly distributed inside, which can provide sufficient illumination in the low-light underwater environment. The heat dissipation component 5 includes two heat dissipation vents 51, the outer walls of which are respectively opened on the front left and right sides of the pressure-resistant housing 1. Multiple heat dissipation fins 52 are fixedly connected to the inner walls of the heat dissipation vents 51. The symmetrical opening of the heat dissipation vents 51 is conducive to uniform heat dissipation on both sides of the device, avoiding local heat accumulation. The heat dissipation fins 52 are made of high thermal conductivity metal material and have a large surface area, which can quickly absorb the heat generated by the internal components of the device. A side lens 6 is fixedly connected to the right side of the pressure-resistant housing 1. The side lens 6 adopts a high-pressure resistant design. The setting of the side lens 6 can expand the shooting angle of the device, so that the device can not only shoot the scene in front of it when operating underwater, but also observe and record the environment to the right, thereby improving the environmental monitoring capability and operational safety of the device. Specifically, in the shooting component 4, the camera 41 acquires images in a high-pressure underwater environment; while the illumination ring 42 surrounds the lens in a circular shape, with multiple LED light sources evenly distributed inside, providing sufficient illumination in low-light underwater environments, solving the brightness problem of shooting in deep sea or dimly lit areas, and ensuring that the camera 41 obtains clear images. In the heat dissipation component 5, the symmetrical opening of the heat dissipation vents 51 facilitates uniform heat dissipation on both sides of the device, avoiding local heat accumulation. Furthermore, the heat dissipation fins 52 are made of high thermal conductivity metal material and have a large surface area, which can quickly absorb the heat generated by the internal components of the device and dissipate the heat to the external environment through heat exchange with the seawater flowing through the heat dissipation vents 51, effectively reducing the internal temperature of the device. In addition, the setting of the side lens 6 can expand the shooting angle of the device, so that when the device is operating underwater, it can not only shoot the scene directly in front, but also observe and record the environment to the right, improving the environmental monitoring capability and operational safety of the device.
[0021] Reference Figure 3 , Figure 4 and Figure 5 The bottom end of the limiting plate 32 engages with the inner wall of the slot 38, securing the limiting plate 32 firmly onto the pressure-resistant housing 1, ensuring that the limiting plate 32 will not loosen or fall off during equipment operation. The upper and lower ends of the rotating bar 33 are both designed with damping, so that the rotating bar 33 can remain fixed after being adjusted to a specific angle. The rear end of the conical extrusion block 24 has the same size as the front side of the inner wall of the inclined ring 25, so that the inclined ring 25 can fit tightly against the rear end of the conical extrusion block 24 to achieve the extrusion action on the bellows 22. The outer wall of the sliding ring 23 is slidably connected to the inner wall of the pressure-resistant cylinder 21, so that the sliding ring 23 can move smoothly back and forth in the pressure-resistant cylinder 21, while maintaining good sealing through the sealing ring 26. Specifically, the bottom end of the limiting plate 32 engages with the inner wall of the slot 38, securing the limiting plate 32 firmly onto the pressure-resistant housing 1. This ensures that the limiting plate 32 will not loosen or fall off during equipment operation, thus providing a stable support foundation for the rotating bar 33 and ensuring the reliable implementation of the rotating bar 33's rotation adjustment function. Both the upper and lower ends of the rotating bar 33 employ a damping design, which increases the resistance during rotation, allowing the rotating bar 33 to remain fixed after adjustment to a specific angle. This prevents the rotating bar 33 from rotating on its own due to equipment shaking or water flow impact, thereby ensuring the stability of the U-shaped plate 34 and the signal transceiver 35, and ensuring signal transmission. The accuracy of the direction is ensured. At the same time, the rear end of the conical extrusion block 24 is the same size as the front side of the inner wall of the inclined ring 25, so that the inclined ring 25 can fit tightly against the rear end of the conical extrusion block 24 to realize the extrusion action of the bellows 22, ensuring the normal operation of the pressure compensation mechanism. Furthermore, the outer wall of the sliding ring 23 is slidably connected to the inner wall of the pressure-resistant cylinder 21, allowing the sliding ring 23 to move smoothly back and forth within the pressure-resistant cylinder 21. At the same time, it can maintain good sealing through the sealing ring 26, ensuring that seawater will not seep into the equipment from the gap between the sliding ring 23 and the pressure-resistant cylinder 21. This enables the adaptive pressure mechanism 2 to work normally in the underwater environment and realize dynamic compensation of the internal pressure of the equipment.
[0022] Working principle: First, the front end of the pressure-resistant cylinder 21 is sealed by the pipe cover 27, while the connecting hole 28 allows seawater to enter the cylinder. When the equipment submerges, the external water pressure acts on the front end of the sliding ring 23 through the connecting hole 28, causing the sliding ring 23 to slide backward along the inner wall of the pressure-resistant cylinder 21. At this time, the bellows 22 is compressed backward by the pull of the sliding ring 23, and the reaction force generated by its elastic deformation reaches a preliminary balance with the external water pressure. Simultaneously, the inclined ring 25 on the inner wall of the sliding ring 23 contacts the conical extrusion block 24, and then... As the sliding ring 23 moves backward, the inclined ring 25 slides along the inclined surface of the conical extrusion block 24, pushing the conical extrusion block 24 toward the pressure-resistant outer shell 1, thereby further extruding the bellows 22, causing the volume of the internal cavity of the bellows 22 to shrink and the internal air pressure to rise, thereby dynamically compensating for the external water pressure. The sealing ring 26 fits tightly against the inner wall of the pressure-resistant cylinder 21 to ensure that seawater does not seep into the main body of the equipment during the sliding process, so that the equipment can automatically adapt to water pressure changes in deep water and avoid damage to the outer shell due to pressure difference. Furthermore, through the auxiliary installation mechanism 3, the inclined pressure plate 31 is fixed to the top of the pressure-resistant housing 1. The inclined angle design guides the water flow to reduce the resistance generated when the equipment moves. The limiting plate 32 is used to limit the swing range of the rotating bar 33. When auxiliary equipment or brackets need to be installed, the rotating bar 33 can rotate around the limiting plate 32, thereby adjusting the angle of the U-shaped plate 34. The U-shaped plate 34 is locked in position by the fixing screw 36, thereby adjusting the orientation of the signal transceiver 35. After the signal transceiver 35 is started, it transmits and receives signals through the underwater acoustic transducer or optical module. In the auxiliary component 37 on the outer wall of the U-shaped plate 34, the buffer plate 371 is made of elastic rubber. When the equipment is hit, the buffer plate 371 can absorb the impact force, thereby protecting the signal transceiver 35. The strip hole 372 is used to insert data cables or fixing ropes, which can realize the connection of external sensors or brackets. The slot 38 allows the quick-plug bracket to be fixed to the upper and lower sides of the equipment through the buckle structure, thereby realizing multi-scenario installation.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
