Description

Technical Field

[0001] The present application belongs to the field of underwater display technology, and in particular relates to an underwater display device. Background Art

[0002] Virtual filming is a display application scenario that uses the display screen as a backdrop for filming, resulting in realistic footage. Compared to traditional green screen and post-production special effects, virtual filming with a display screen as a backdrop is more efficient, cost-effective, and realistic. Underwater virtual filming involves placing the display screen underwater, using the screen to simulate various deep-sea scenes for deep-sea footage. This not only allows for diverse underwater scenes but also realistically simulates the floating state of people and objects in water, making the footage even more realistic. However, as electronic products, water can cause serious circuit and safety issues when used on display screens. Therefore, ensuring the waterproof seal of the display screen is a crucial challenge for underwater virtual filming.

[0003] In summary, the waterproof level and pressure resistance of existing underwater display technologies cannot meet the requirements of underwater virtual shooting. Summary of the Invention

[0004] In view of this, an embodiment of the present application provides an underwater display device to solve the technical problem that the waterproof level and pressure resistance of existing underwater display technology cannot meet the requirements of underwater virtual shooting.

[0005] A first aspect of an embodiment of the present application provides an underwater display device for use in an underwater area. The underwater display device includes a display screen, an insulating layer, and an insulating sealing liquid. The insulating layer is used to construct a display screen placement cavity in the underwater area. The inside and outside of the display screen placement cavity are isolated from each other. The display screen placement cavity is filled with a sealing liquid. The display screen is arranged in the display screen placement cavity and immersed in the sealing liquid.

[0006] The embodiment of the present application includes a display screen, an insulating layer, and an insulating sealing liquid. The insulating layer is used to create a display screen placement cavity in the underwater area, isolating the interior and exterior of the display screen placement cavity. The display screen placement cavity is filled with a sealing liquid, and the display screen is positioned within the cavity and submerged in the sealing liquid. With this structure, while maintaining a high waterproof rating, the sealing liquid can balance the pressure inside and outside the insulating layer, improving the device's compressive resistance and enabling underwater use of the display device, thus meeting the requirements of underwater photography.

[0007] In one embodiment, the sealing liquid is a colorless transparent liquid, and the insulating layer is made of a transparent material.

[0008] The sealing liquid in the embodiment of the present application is a colorless and transparent liquid, and the insulating layer is composed of a transparent material. Compared with air, the colorless and transparent sealing liquid is a liquid propagation medium with less light loss underwater, ensuring better shooting quality, and the insulating layer composed of transparent material can ensure good light transmittance, further optimizing the shooting quality.

[0009] In one embodiment, the sealing liquid includes dimethyl silicone oil.

[0010] The sealing liquid of the embodiment of the present application includes dimethyl silicone oil, and the refractive index of dimethyl silicone oil is 1.39 to 1.41, which is very close to the refractive index of water (1.333). This close refractive index helps to reduce the Fresnel reflection and total reflection phenomenon that occurs when light passes through the interface of different media, thereby reducing light loss and ensuring the image quality transmitted from the display screen to the camera lens. In addition, dimethyl silicone oil has good wettability, insulation and hydrophobicity, and can fully fill each gap of the display screen, forming a liquid seal layer on the display screen to avoid water vapor damage to the circuit. It can also effectively prevent leakage discharge and protect the safety of deep water areas. In addition, dimethyl silicone oil has a high flash point, low volatility and chemical inertness, and will not cause problems such as explosion and corrosion of circuits. Among them, low volatility also ensures the long-term use of the sealing liquid. Dimethyl silicone oil is biologically inert and non-toxic, which further improves the safety of the device.

[0011] In one embodiment, the insulating layer and the inner side wall and inner bottom wall of the underwater area are combined to form a display screen placement cavity.

[0012] In this embodiment of the present application, the insulating layer, along with the inner sidewalls and inner bottom wall of the underwater area, encloses a display screen cavity. This display screen cavity, constructed using the underwater wall, reduces the surface area in contact with water, ensuring better sealing. Furthermore, the wall can be used to route power-related wiring, ensuring power supply security.

[0013] In one embodiment, the insulating layer is a sealed box, the interior of the sealed box forms the display screen placement cavity, and the display screen is fixed to the inner wall of the sealed box.

[0014] In this embodiment of the present application, the insulating layer is a sealed box, the interior of which forms the display screen placement cavity, and the display screen is fixed to the inner wall of the sealed box. The sealed box is movable, and when placed underwater, the display screen can be placed in any position underwater, providing greater flexibility and adapting to more complex underwater scenarios.

[0015] In one embodiment, a connecting rod, a roller and a roller locking component are provided at the bottom of the sealed box body. The length of the connecting rod is adjustable. One end of the connecting rod is connected to the bottom of the sealed box body, and the other end is connected to the roller. The roller locking component is used to lock or release the roller.

[0016] The bottom of the sealed box in the embodiment of the present application is provided with a connecting rod, a roller, and a roller locking member. The length of the connecting rod is adjustable, one end of which is connected to the bottom of the sealed box and the other end is connected to the roller. The roller locking member is used to lock or release the roller. The roller can be quickly moved to a specified position, and the roller locking member can also be used to lock the roller in a specified position, thereby preventing the sealed box from moving during filming. The roller can be connected to the roller by an adjustable length connecting rod, and the height of the roller can be adjusted to ensure the stability of the sealed box.

[0017] In one embodiment, the insulating layer includes a plurality of insulating plates connected to each other, the insulating plates are connected by sealant, and the refractive index difference between the sealant and the insulating plates is within a preset range.

[0018] The insulation layer of the present embodiment comprises a plurality of interconnected insulation panels, which are connected by a sealant. The difference in refractive index between the sealant and the insulation panels is within a predetermined range. By ensuring that the difference in refractive index between the sealant and the insulation panels is within this predetermined range, Fresnel reflection and total internal reflection are further reduced, thereby improving the overall optical performance of the device.

[0019] In one embodiment, a supporting structure is further included, which is connected to the display screen. The supporting structure includes a sling and a pulley assembly. One end of the sling is connected to the top of the display screen, and the other end of the sling passes through the pulley assembly and is fixed.

[0020] The embodiment of the present application further includes a support structure connected to the display screen. The support structure includes a sling and pulley assembly. One end of the sling is connected to the top of the display screen, and the other end of the sling passes through the pulley assembly and is secured thereto. By providing the sling and pulley assembly at the top of the display screen, the pulley assembly can be used to lift the display screen for easier maintenance.

[0021] In one embodiment, a desiccant placement groove is provided at the bottom of the display screen placement cavity, and the desiccant placement groove is used to place desiccant. The inner wall of the display screen placement cavity is connected to the desiccant placement groove through a sliding component, and the desiccant placement groove is used to move along the length direction of the display screen under the drive of the sliding component.

[0022] In the embodiment of the present application, a desiccant placement groove is provided at the bottom of the display screen placement cavity, and the desiccant placement groove is used to place desiccant. The inner wall of the display screen placement cavity is connected to the desiccant placement groove by a sliding assembly, and the desiccant placement groove is used to move along the length direction of the display screen under the drive of the sliding assembly. Since the density of water is greater than that of sealing oil, when a small amount of water enters the sealing liquid, the water will be deposited at the bottom of the display screen placement cavity. Therefore, by providing a desiccant placement groove at the bottom, the moisture deposited at the bottom can be absorbed, further ensuring electrical safety. By providing a sliding assembly, the desiccant placement groove can be driven to move along the length direction of the display screen, so that the trajectory of the desiccant placement groove can cover the entire display screen to achieve a better water absorption effect.

[0023] In one embodiment, a cover plate is provided on the top of the display screen placement cavity.

[0024] In the embodiment of the present application, a cover plate is provided on the top of the display screen placement cavity, so that the interior of the display screen placement cavity can be waterproof or dustproof, thereby further improving the safety of the device.

[0025] The first aspect of the present application provides an underwater display device for use in underwater areas. The device comprises a display screen, an insulating layer, and an insulating sealing liquid. The insulating layer is used to create a display screen placement cavity in the underwater area, isolating the interior and exterior of the display screen placement cavity from each other. The display screen placement cavity is filled with sealing liquid, and the display screen is disposed in the display screen placement cavity and immersed in the sealing liquid. With the above structure, while ensuring a high waterproof rating, the sealing liquid can balance the pressure inside and outside the insulating layer, thereby improving the device's pressure resistance and enabling the underwater display device to meet the requirements of underwater photography.

[0036] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details.

[0043] The embodiment of the present application provides an underwater display device, which is used in underwater areas. The underwater display device includes a display screen, an insulating layer and a sealing liquid. The insulating layer is used to construct a display screen placement cavity in the underwater area. The inside and outside of the display screen placement cavity are isolated from each other. The display screen placement cavity is filled with a sealing liquid. The display screen is arranged in the display screen placement cavity and immersed in the sealing liquid. The sealing liquid is an insulating colorless and transparent liquid. The insulating layer is made of a transparent material. Through the above structure, under the premise of ensuring a high waterproof level, the sealing liquid can balance the pressure inside and outside the insulating layer, thereby improving the pressure resistance of the device. The sealing liquid is a colorless and transparent liquid. Compared with air, the liquid propagation medium has less light loss underwater, ensuring better shooting quality, so that the underwater display device can meet the needs of underwater shooting.

[0044] In applications, underwater areas can be artificially designed and constructed underwater environments, usually located indoors or in semi-enclosed spaces for easy power supply and maintenance, such as aquarium display tanks, swimming pools, underwater theaters, and underwater studios.

[0045] In applications, the display screen can be a light emitting diode (LED) display screen, a liquid crystal display (LCD) display screen, an organic light emitting diode (OLED) display screen, a quantum dot light emitting diode (QLED) display screen, etc.

[0046] like Figure 1 As shown, the underwater display device 2 provided in this embodiment is arranged in the underwater area 1. The underwater display device 2 includes a display screen 21, an insulating layer 22 and an insulating sealing liquid 24. The insulating layer 22 is used to construct a display screen placement cavity 23 in the underwater area 1. The inside and outside of the display screen placement cavity 23 are isolated from each other. The display screen placement cavity 23 is filled with the sealing liquid 24. The display screen 21 is arranged in the display screen placement cavity 23 and immersed in the sealing liquid 24.

[0047] In practice, the display screen cavity 23 created by the insulating layer 22 in the underwater area 1 can be a closed cavity formed by the insulating layer 22 itself, or it can be a cavity enclosed by the wall 11 of the underwater area 1. The cross-section of the display screen cavity 23 can be triangular, rectangular, circular, semicircular, or any other shape, as long as it can accommodate the display screen 21. The interior and exterior of the display screen cavity 23 are isolated from each other, preventing water from the underwater area 1 from entering the cavity 23, thus ensuring the waterproofing of the display screen.

[0048] In an embodiment of the present application, an underwater display device includes a display screen, an insulating layer, and an insulating sealing liquid. The insulating layer is used to create a display screen placement cavity in the underwater area, isolating the interior and exterior of the display screen placement cavity. The display screen placement cavity is filled with a sealing liquid, and the display screen is positioned within the cavity and submerged in the sealing liquid. A display screen placement cavity 23, formed by the insulating layer 22, is isolated from the underwater area 1, forming the first waterproofing step for the display screen. The display screen placement cavity 23 is filled with an insulating sealing liquid 24, and the display screen 21 is immersed in the insulating sealing liquid 24, thereby forming a second waterproofing step for the display screen 21. Compared to traditional glue sealing processes, liquid sealing methods can provide superior sealing effects. The sealing liquid 24 fills the entire display screen placement cavity 23, forming a continuous liquid barrier that effectively prevents moisture from invading the display screen 21. Furthermore, the insulating properties of the sealing liquid completely prevent leakage discharge, thereby avoiding safety issues caused by leakage into the underwater area. The sealing liquid is in liquid form, and its density is closer to that of water than that of air, which can offset the pressure exerted on the insulation layer in deep water and greatly reduce the mechanical performance requirements of the insulation layer. This characteristic is crucial for maintaining the long-term stable operation of the display screen 21, especially in deep water environments, where the insulation layer 22 may need to withstand greater pressure. The density of the sealing liquid 24 is similar to that of water, which can balance the external water pressure to a certain extent, reduce the pressure burden on the insulation layer 22, and thus extend its service life and reduce the requirements for material strength. In addition, the display screen is immersed in the sealing liquid. The sealing liquid and water are both liquid and have a closer refractive index, which avoids the light loss of the display screen caused by the refractive index difference between air and water, so that the images captured by the camera have better effects and can meet the needs of underwater shooting.

[0049] In one embodiment, the sealing liquid 24 is an insulating colorless transparent liquid, and the insulating layer 22 is made of a transparent material.

[0050] In practice, the sealing liquid 24 is a colorless, transparent silicone liquid, such as at least one of methyl silicone oil, ethyl silicone oil, phenyl silicone oil, methyl hydrogen silicone oil, methylphenyl silicone oil, methylchlorophenyl silicone oil, methylethoxy silicone oil, methyltrifluoropropyl silicone oil, methylvinyl silicone oil, methylhydroxy silicone oil, ethyl hydrogen silicone oil, and hydroxy hydrogen silicone oil. The insulating layer 22 can be made of transparent glass or a polymer material (such as acrylic or polycarbonate). It can be manufactured using an integrated molding process or by assembling multiple insulating panels.

[0051] The sealing liquid in the embodiment of the present application is an insulating colorless transparent liquid, and the insulating layer is made of a transparent material. Using a colorless transparent liquid as the sealing liquid can ensure good insulation. In an underwater environment, the propagation of light between different media (such as from air to water) will be affected by the refractive index, which may cause image distortion or reduced brightness. Using a colorless transparent liquid with a refractive index close to that of water as the sealing liquid 24 can significantly reduce the refractive loss generated when light is transmitted between the display screen 21 and the external water body, thereby ensuring that the light emitted from the display screen can reach the camera lens with higher fidelity, making the captured image clearer and more realistic. The insulating layer composed of transparent material can ensure good light transmittance, further optimizing the shooting quality.

[0052] In one embodiment, the sealing fluid 24 includes dimethyl silicone oil.

[0053] In applications, the sealing liquid 24 may include dimethyl silicone oil, or directly use dimethyl silicone oil.

[0054] The sealing liquid 24 of the embodiment of the present application includes dimethyl silicone oil. Since the density of dimethyl silicone oil is close to that of water (about 0.96-0.97 g / cm 3 ), a property that helps balance external water pressure in deep water environments, effectively alleviating the pressure on the insulation layer. This not only reduces the mechanical properties requirements for the insulation layer material, but also simplifies its design and keeps costs under control. Furthermore, the refractive index of dimethyl silicone oil is 1.39-1.41, very close to that of water (1.333). This close refractive index helps reduce Fresnel reflection and total internal reflection at the interface between different media, thereby reducing light loss and ensuring image quality between the display and the camera lens. This is particularly important for underwater photography, as it ensures clearer and more realistic images. Furthermore, dimethyl silicone oil has excellent wettability, insulation, and hydrophobicity, allowing it to fully fill every gap in the display screen, forming a liquid seal to prevent moisture from damaging the circuitry. It also effectively prevents leakage discharge, ensuring safety in deep water. Furthermore, dimethyl silicone oil has a high flash point, low volatility, and chemical inertness, preventing explosions and circuit corrosion. Its low volatility also ensures the long-term usability of the sealing fluid. Dimethyl silicone oil is biologically inert and non-toxic, further improving the safety of the device.

[0055] In one embodiment, the insulating layer 22 includes a plurality of insulating plates connected to each other. The insulating plates are connected by sealant, and the refractive index difference between the sealant and the insulating plates is within a preset range.

[0056] In application, the insulating layer 22 can be formed by splicing together several prefabricated insulating panels. The insulating panels are seamlessly connected to each other by sealant, and the insulating panels can also be seamlessly connected to the wall by sealant. The sealant is a colorless and transparent sealant with a refractive index close to that of the insulating panels, such as epoxy sealant, polyurethane sealant, silicone-based sealant, acrylic sealant and other sealants. The refractive index difference between the sealant and the insulating panels is within a preset range, such as 8%, 10%, 12%, etc. In addition to the refractive index difference between the sealant and the insulating panels being within a preset range, a material with a refractive index close to that of water is also selected. Among them, the refractive index of the insulating panels is less than 1.6, and the difference between the refractive index of the insulating panels and that of water also needs to meet a preset range, such as 8%, 10%, 12%, etc., to further reduce Fresnel reflection and total reflection phenomena and improve the overall optical performance.

[0057] The insulation layer of the present embodiment comprises several interconnected insulation panels, which are connected by a sealant. The difference in refractive index between the sealant and the insulation panels is within a predetermined range. By ensuring that the difference in refractive index between the sealant and the insulation panels is within this predetermined range, Fresnel reflection and total internal reflection are further reduced, thereby improving the overall optical performance of the device.

[0058] In one embodiment, the insulation board has a thickness of 1 to 20 cm.

[0059] In applications, insulation boards with a thickness of 1 to 20 cm can be lightweight while ensuring sufficient strength.

[0060] In one embodiment, Figures 1 to 3 As shown, the insulating layer 22 and the inner side wall and inner bottom wall of the underwater area 1 enclose a display screen placement cavity 23 .

[0061] In practice, the walls 11 of the underwater area 1 can be used as the side walls of the display screen placement cavity 23. For example, for a rectangular underwater area 1, a corner of the underwater area 1 can be used as the target area. The left and right ends of the insulating layer 22 are seamlessly connected to the two walls using sealant, and the bottom of the insulating layer 22 is connected to the ground of the underwater area 1. Thus, the insulating layer 22 and the inner side walls and inner bottom wall of the underwater area 1 enclose a triangular display screen placement cavity 23.

[0062] In application, the three walls of the underwater area 1 (one end of wall a is connected to wall b, and the other end of wall a is connected to wall c) can also be used as the target area, and the insulating layer 22 is placed facing wall a. The two ends of the insulating layer 22 are seamlessly connected to wall b and wall c respectively through sealant, and the bottom of the insulating layer 22 is connected to the ground of the underwater area 1, so that the insulating layer 22 and the inner side wall and inner bottom wall of the underwater area 1 enclose a rectangular area of ​​the display screen placement cavity 23.

[0063] In applications, a circular or arc-shaped area in the underwater area 1 can be selected as the target area. The insulating layer 22 can be designed into a matching arc shape, seamlessly connecting with the surrounding wall, to suit applications requiring a wider field of view. The curvature radius of the insulating layer 22 must match the curvature of the underwater area 1 to ensure a seamless connection.

[0064] In application, power lines can be pre-arranged inside the wall to ensure the stability and safety of the power supply. The space inside the wall can be used to hide wires and cables to prevent wires from being exposed in the underwater environment, thereby reducing the risk of electric shock. The wall can serve as part of the electrical isolation to help isolate the electronic equipment in the display screen placement cavity 23 from the underwater environment. This isolation not only prevents water from entering the display screen placement cavity 23, but also reduces the risk of current leakage, further ensuring the safe operation of the equipment. The space inside the wall can also be used to install power management systems, such as circuit breakers, switches, etc., to facilitate the control and monitoring of the power supply of the display screen 21. The installation position of these devices close to the display screen 21 can reduce the length of the wires, thereby reducing signal attenuation and power loss.

[0065] In this embodiment, the display screen cavity is formed by enclosing an insulating layer with the inner sidewalls and inner bottom wall of the underwater area. This display screen cavity, constructed using the walls of the underwater area, reduces the surface area in contact with water, thereby ensuring better sealing. Furthermore, the walls can be used to route power-related wiring, ensuring power supply security.

[0066] In one embodiment, the liquid level of the sealing liquid is consistent with the water level of the underwater area 1 .

[0067] In use, the sealing liquid level can be consistent with the water level in underwater area 1, or even higher, effectively balancing underwater pressure. A sealing liquid level higher than the display screen and lower than the insulating layer 22 prevents display screen 21 from being exposed to air, thereby reducing light loss caused by the refractive index difference between air and water and ensuring a good seal. Furthermore, a sealing liquid level lower than the insulating layer 22 prevents the sealing liquid from overflowing and contacting the water surface in underwater area 1, further enhancing the waterproof performance of the entire system.

[0068] In one embodiment, an ultrasonic liquid level sensor is installed in the display screen placement cavity 23 at a certain distance above the display screen 21 to monitor the liquid level of the sealing liquid in real time. The data output end of the ultrasonic liquid level sensor is connected to the control system to convert the liquid level information into an electrical signal and output it to the control system. When the control system receives the signal from the liquid level sensor, it determines whether to start the rehydration program based on a preset minimum liquid level threshold (slightly higher than the highest point of the display screen 21). Once the liquid level is too low, the control system will start the rehydration program.

[0069] In one embodiment, a small water pump is provided near underwater area 1 as a rehydration pump. The rehydration pump is connected to display screen cavity 23 via a liquid inlet pipeline. The pipeline inlet is located in a position (e.g., a cover plate) within display screen cavity 23 that is higher than display screen 21. When the control system initiates the rehydration process, the rehydration pump is activated to pump the sealing liquid from the sealing liquid storage tank into display screen cavity 23.

[0070] In one embodiment, a check valve is installed on the liquid inlet pipeline to prevent the sealing liquid from flowing back.

[0071] In one embodiment, an overflow detection sensor is further provided in the display screen placement cavity 23, and a data output terminal of the overflow detection sensor is connected to the control system. Once the sealing liquid level reaches the highest point predetermined by the control system, the refill pump is immediately turned off.

[0072] In one embodiment, a supporting structure 25 is further included, and the supporting structure 25 is connected to the display screen 21 .

[0073] In use, the support structure 25 is used to support the display screen, allowing it to be stably placed at a specified angle, such as vertically, tilted, or horizontally. The support structure 25 can be a steel structure bracket, steel cable, or other structure. The support structure 25 can be located on the back or side of the display screen 21 to secure the display screen 21 to the wall 11. The support structure 25 can also be located at the bottom of the display screen 21 to secure the display screen 21 to the bottom of the underwater area 1. The support structure 25 can also be located at the top of the display screen 21 to secure the display screen 21 to the top wall of a building, etc. The above are merely examples of securing methods and do not constitute a limitation of this solution.

[0074] In use, a support frame is installed on the back of the display screen 21 and connected to the display screen 21 using fasteners (such as screws). One end of the support frame is connected to a fixed point on the back of the display screen 21, and the other end is connected to the wall 11 using expansion bolts or other fixing methods. Reinforcement ribs can also be installed at key locations on the support frame to improve the stability and compressive strength of the overall structure. Cushioning material can also be used in the contact area between the display screen 21 and the support frame to reduce the impact of vibration on the display screen 21.

[0075] In one embodiment, Figure 2 As shown, the support structure 25 includes a sling 251 and a pulley assembly. One end of the sling 251 is connected to the top of the display screen 21, and the other end of the sling 251 passes through the pulley assembly and is fixed.

[0076] In practice, a lifting lug for the cable 251 to pass through can be installed at the top of the display screen 21. A pulley assembly can be installed on the upper shell of the building's inner roof wall. One end of the cable 251 is secured to the lifting lug, while the other end passes through the lug and around the pulley assembly to secure it at a designated location. By releasing the end of the cable 251, the display screen can be lifted using the pulley assembly for easier maintenance. Alternatively, a fixed structure such as a steel frame of a certain height can be installed in the underwater area 1, and the pulley can be secured to the steel frame. The height of the steel frame must be greater than the sum of the height of the display screen and the depth of the underwater area.

[0077] The embodiment of the present application further includes a support structure connected to the display screen. The support structure includes a sling and pulley assembly. One end of the sling is connected to the top of the display screen, and the other end of the sling passes through the pulley assembly and is secured thereto. By providing the sling and pulley assembly at the top of the display screen, the pulley assembly can be used to lift the display screen for easier maintenance.

[0078] In one embodiment, a cover plate is provided on the top of the display screen placement cavity.

[0079] In application, when the display screen is fixed with the sling 251 , a through hole for the sling 251 to pass through can be opened on the cover plate, and glue can be poured at the through hole to seal the gap between the through hole and the sling 251 .

[0080] In the embodiment of the present application, a cover plate is provided on the top of the display screen placement cavity, which can achieve waterproof or dustproofing of the interior of the display screen placement cavity, further improving the safety of the device.

[0081] In one embodiment, Figure 3 As shown, a desiccant placement groove 26 is provided at the bottom of the display screen placement cavity 23 , and the desiccant placement groove 26 is used to place a desiccant.

[0082] In application, a desiccant placement groove 26 can be set at the bottom of the display screen placement cavity 23, and desiccant can be placed in the desiccant placement groove 26. The desiccant placement groove 26 can be set as one or more. When there is one desiccant placement groove 26, its length is equal to the length of the display screen placement cavity 23, and can also be less than the length of the display screen. The desiccant can be anhydrous sodium sulfate, anhydrous calcium chloride, anhydrous magnesium chloride, anhydrous potassium carbonate, potassium dihydrogen phosphate and other hygroscopic inorganic salts. The desiccant can be placed directly in the desiccant placement groove 26, and a structure such as a drying bag can also be provided to hold the desiccant. In order to allow water to enter the desiccant placement groove 26 and be absorbed by the desiccant, a water hole can be opened on the desiccant placement groove 26. The water hole can be set as one or more and can be distributed on the side or top surface of the desiccant placement groove 26, as long as it can achieve internal and external communication. Since the density of water is greater than that of sealing oil, when a small amount of water enters the sealing liquid, the water will be deposited at the bottom of the display screen placement cavity 23. Therefore, by providing a desiccant placement groove 26 at the bottom, moisture deposited at the bottom can be absorbed, further ensuring electrical safety.

[0083] In this embodiment of the present application, a desiccant slot is provided at the bottom of the display cavity. This slot is used to hold desiccant. Because water has a greater density than sealing oil, even a small amount of water in the sealing fluid will settle at the bottom of the display cavity. Therefore, the desiccant slot at the bottom absorbs any water that settles, further ensuring electrical safety.

[0084] In one embodiment, the inner wall of the display screen placement cavity 23 is connected to the desiccant placement groove 26 via a sliding assembly. The desiccant placement groove 26 is configured to move along the length direction of the display screen 21 under the drive of the sliding assembly.

[0085] In application, when the length of the desiccant placement groove 26 is smaller than the display screen 21, a sliding assembly is provided to drive the desiccant placement groove 26 to move along the length direction of the display screen 21, so that the trajectory of the desiccant placement groove 26 can cover the entire display screen 21 to achieve a better water absorption effect. The sliding assembly can be implemented in a manner that a slide rail and a slider cooperate with each other, such as fixing the slide rail to the wall 11, fixing the slider to the desiccant placement groove 26, and the slider and the slide rail are slidably connected. The slider is connected to the motor through a transmission component, so that the slider can be driven by the motor to achieve the movement of the slider along the slide rail. In addition, limit switches are installed at both ends of the slide rail. When the desiccant placement groove 26 moves to the end of the slide rail, the limit switch will be triggered, sending a signal to the drive motor to stop the motor.

[0086] In this embodiment of the present application, the inner wall of the display screen cavity is connected to the desiccant trough via a sliding assembly. Driven by the sliding assembly, the desiccant trough is configured to move along the length of the display screen. By providing the sliding assembly, the desiccant trough can be driven to move along the length of the display screen, allowing the desiccant trough's trajectory to cover the entire display screen, achieving better water absorption.

[0087] In one embodiment, Figures 4-6 As shown, the insulating layer 22 is a sealed box body, a display screen placement cavity 23 is formed inside the sealed box body, and the display screen 21 is fixed to the inner wall of the sealed box body.

[0088] In practice, the insulating layer 22 can be directly used to form a sealed enclosure, which can then be placed underwater. This allows the display screen to be placed anywhere underwater, providing greater flexibility. The display screen 21 can be secured directly to the inner wall of the sealed enclosure via its back surface, or it can be secured to the inner wall of the sealed enclosure from the side, top, or bottom surfaces. The specific securing method is not limited. When the insulating layer 22 forms a sealed enclosure, the sealing liquid is ensured to fill the entire enclosure.

[0089] In this embodiment of the present application, the insulating layer is a sealed box, the interior of which forms the display screen placement cavity, and the display screen is fixed to the inner wall of the sealed box. The sealed box is movable, and when placed underwater, the display screen can be placed in any position underwater, providing greater flexibility and adapting to more complex underwater scenarios.

[0090] In one embodiment, Figure 4 As shown, the sealed box can be placed horizontally at the bottom of the underwater area 1, and the display screen 21 can be set horizontally, and the back of the display screen 21 can be fixed to the inner wall of the sealed box.

[0091] In applications such as Figure 5 As shown, the sealed box can also be fixed obliquely in the angle area formed by the side wall and the bottom wall of the underwater area 1.

[0092] In applications such as Figure 6 As shown, the sealed box can also be fixed vertically on a wall of the underwater area 1.

[0093] In one embodiment, a connecting rod, a roller and a roller locking component are provided at the bottom of the sealed box body. The length of the connecting rod is adjustable. One end of the connecting rod is connected to the bottom of the sealed box body and the other end is connected to the roller. The roller locking component is used to lock or release the roller.

[0094] To facilitate the movement of the sealed box, rollers can be installed on the bottom of the box, allowing it to be quickly moved to a desired location. A roller locking member can also be used to lock the rollers in a designated position, preventing the box from moving during filming. The rollers are connected by a length-adjustable connecting rod, allowing for adjustable height, ensuring the stability of the sealed box.

[0095] The bottom of the sealed box in the embodiment of the present application is provided with a connecting rod, a roller, and a roller locking member. The length of the connecting rod is adjustable, one end of which is connected to the bottom of the sealed box and the other end is connected to the roller. The roller locking member is used to lock or release the roller. The roller can be quickly moved to a specified position, and the roller locking member can also be used to lock the roller in a specified position, thereby preventing the sealed box from moving during filming. The roller can be connected to the roller by an adjustable length connecting rod, and the height of the roller can be adjusted to ensure the stability of the sealed box.

[0096] In one embodiment, a retractable or foldable support member is provided on a side of the sealed box away from the display screen.

[0097] In application, a retractable support member is provided, and the support member is connected to the back of the sealed box by a hinge, so that the support member can rotate around the hinge to achieve the action of unfolding or folding. The support member is made of lightweight materials, such as aluminum alloy or carbon fiber, to reduce the overall weight. When the sealed box needs to be placed at an angle, the support member can be unfolded from the back of the sealed box to ensure the stability of the sealed box in the tilted state. In addition, in order to further improve the practicality and flexibility of the support legs, the support member is also provided as a retractable structure, which can adapt to different tilt angles by adjusting the length of the support member. A locking mechanism is also provided next to the support member. When the support member is unfolded to the appropriate position, the support member can be locked by the locking mechanism to ensure that the support member will not be accidentally folded during use. The retractable support member is used to achieve stable support for the sealed box when the sealed box is tilted.
