A protective underwater photography device

Abstract

This utility model discloses a protective underwater photography device, relating to the field of underwater photography technology. The device includes a protective component, inside which a camera is housed. A storage component is located on the back of the protective component, and a squeezing component is located inside the storage component. A sealing component is located at the bottom of the storage component. By opening the sealing component and driving the squeezing component, water inside the storage component can be expelled through the sealing component under pressure. Once the weight of the storage component is adjusted to a suitable value, the squeezing component stops operating, and the sealing component is closed again. This design allows the overall weight of the device to be adjusted according to different water depths, thereby achieving adaptive buoyancy control. This effectively avoids the need for operators to continuously adjust the magnitude and direction of applied force, and also significantly reduces the complexity and difficulty of operation.

Description

Technical Field

[0001] This utility model belongs to the field of underwater photography technology, and specifically relates to an underwater photography device with protective function. Background Technology

[0002] With the booming development of marine exploration, underwater engineering operations, ecological observation, and underwater recreation, the application scope of underwater photography technology continues to expand. However, the underwater environment presents multiple complex challenges, including high pressure, strong currents, corrosive media, and suspended sediment, which can easily lead to damage to camera equipment or a decline in image quality. Therefore, equipping the equipment with specialized protective devices has become an important prerequisite for ensuring the reliability of underwater photography operations and the quality of images.

[0003] Because water pressure varies significantly at different depths, the buoyancy of the entire equipment, including the protective gear and camera, changes depending on the depth. In shallow water, the buoyancy is greater, requiring operators to apply downward force to maintain stability. In deeper water, increased hydrostatic pressure can cause slight deformation of the protective shell, reducing the volume of water displaced and significantly decreasing buoyancy. In this case, operators must then apply upward force to prevent the equipment from sinking. This dynamic buoyancy characteristic, changing with water depth, requires operators to continuously adjust the magnitude and direction of applied force, significantly increasing the complexity and difficulty of actual operation. Utility Model Content

[0004] To address the issue that the buoyancy of the entire equipment consisting of a protective device and a camera varies when taking photos at different water depths, this invention proposes an underwater photography device with protective functions to overcome the aforementioned technical problems existing in related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an underwater photography device with protective function, including a protective component, a camera is installed inside the protective component, a storage component is installed on the back of the protective component, a compression component is installed inside the storage component, and a sealing component is installed at the bottom of the storage component.

[0007] The storage component is used to store water, and the squeezing component is used to squeeze the water inside the storage component so that the water is discharged from the inside of the storage component through the sealing component, while the overall weight of the storage component changes.

[0008] Furthermore, the protective assembly includes a lower shell and an upper shell, the upper shell being disposed on top of the lower shell, a lens protective cover being fixedly connected to the front end of the lower shell, the camera being disposed inside the lower shell, the upper shell and the lens protective cover, connecting plates being fixedly connected to both sides of the lower shell and the upper shell, and a connecting bolt being threadedly connected to the top of the connecting plate on the outer side of the upper shell, the connecting bolt passing through the two connecting plates.

[0009] Furthermore, a sealing groove is provided on the top of the lower shell, and a sealing strip is movably connected inside the sealing groove. The sealing strip is fixedly connected to the upper shell. Sealing rings are threadedly connected to the front ends of the lower shell and the upper shell. The sealing rings are threadedly connected to the lens hood. Limiting rings are fixedly connected to the outer surfaces of the lower shell, the upper shell, and the lens hood.

[0010] Furthermore, the storage component includes a connecting frame, which is fixedly installed at the rear end of the lower shell, and a storage box is fixedly installed on one side of the mounting frame.

[0011] Furthermore, the extrusion assembly includes an extrusion screw, which is rotatably connected to the storage box. An extrusion plate is threadedly connected to the outer surface of the extrusion screw, and the extrusion plate is movably connected to the storage box. A guide rod is fixedly connected inside the storage box, and the extrusion plate is movably connected to the guide rod. The top end of the extrusion screw extends to the outside of the storage box and is fixedly connected to a control panel.

[0012] Furthermore, the sealing assembly includes a conical groove, which is formed at the bottom of the inner wall of the storage box. A conical plug is fitted onto the inner wall of the conical groove. A mounting bracket is fixedly connected to the bottom of the storage box. An adjusting screw is threadedly connected to the bottom of the mounting bracket. The top end of the adjusting screw passes through the mounting bracket and is fixedly connected to the bottom of the conical plug.

[0013] Furthermore, a discharge pipe is fixedly connected to the top of the storage box, and a sealing cap is threaded onto the outer surface of the discharge pipe. A handle is fixedly connected between the lower shell and the storage box.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model allows water in the collection component to be discharged through the sealing component under the squeezing action by opening the sealing component and driving the squeezing component. When the weight of the collection component is adjusted to a suitable value, the operation of the squeezing component is stopped and the sealing component is closed again. The above settings enable the overall weight of the device to be adjusted according to different water depths, thereby achieving adaptive control of buoyancy, effectively avoiding the need for operators to continuously adjust the magnitude and direction of the applied force, and also significantly reducing the complexity and difficulty of operation.

[0016] 2. This utility model achieves a reliable seal by placing the upper shell on top of the lower shell, allowing the sealing strip to be inserted into the sealing groove as the upper shell is pressed down; then, rotating the connecting bolts secures the upper and lower shells together via the connecting plates on both sides; finally, rotating the sealing ring tightly covers the connection between the upper shell and the lens cover, ensuring a reliable seal. The assembly process is simple and convenient, effectively ensuring easy installation of the camera inside the lower shell, upper shell, and lens cover, and guaranteeing good sealing performance at the connection points.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-7 As shown, this utility model is an underwater photography device with protective function, including a protective component 1, a camera 2 is arranged inside the protective component 1, a storage component 3 is arranged on the back of the protective component 1, a compression component 4 is arranged inside the storage component 3, and a sealing component 5 is arranged at the bottom of the storage component 3.

[0031] The storage component 3 is used to store water, and the squeezing component 4 is used to squeeze the water inside the storage component 3 so that the water is discharged from the inside of the storage component 3 through the sealing component 5, and at the same time the overall weight of the storage component 3 changes.

[0032] Water is poured into the housing component 3, and the operator holds the device, causing the protective component 1 to sink the camera 2 into the water under the gravity of the housing component 3. When the appropriate water depth is reached and filming is to be performed, the sealing component 5 is opened, and the squeezing component 4 is driven. The downward-moving squeezing component 4 can squeeze the water inside the housing component 3, allowing the water to be discharged through the sealing component 5. When the operator feels comfortable supporting the device, the driving of the squeezing component 4 is stopped, and the sealing component 5 is closed. Then, filming is performed at the water depth.

[0033] By opening the sealing assembly 5 and driving the squeezing assembly 4, the water in the receiving assembly 3 can be discharged through the sealing assembly 5 under the squeezing action; when the weight of the receiving assembly 3 is adjusted to a suitable value, the operation of the squeezing assembly 4 is stopped, and the sealing assembly 5 is closed again; the above settings enable the overall weight of the device to be adjusted according to different water depths, thereby achieving adaptive control of buoyancy, effectively avoiding the need for operators to continuously adjust the magnitude and direction of the applied force, and also significantly reducing the complexity and difficulty of operation.

[0034] In one embodiment, the protective component 1 includes a lower shell 101 and an upper shell 102. The upper shell 102 is disposed on top of the lower shell 101. A lens protective cover 103 is fixedly connected to the front end of the lower shell 101. The camera 2 is disposed inside the lower shell 101, the upper shell 102, and the lens protective cover 103. Connecting plates 104 are fixedly connected to both sides of the lower shell 101 and the upper shell 102. A connecting bolt 105 is threadedly connected to the top of the connecting plate 104 on the outer side of the upper shell 102. The connecting bolt 105 passes through the two connecting plates 104.

[0035] By moving the camera position of camera 2 inside the lens cover 103 and placing the main body of camera 2 inside the lower shell 101, then placing the upper shell 102 on top of the lower shell 101, and making the front end of the upper shell 102 contact the rear end of the lens cover 103, and then rotating the connecting bolt 105, the connecting bolt 105 can be used to connect the upper shell 102 and the lower shell 101 together through the two connecting plates 104.

[0036] In one embodiment, for the lower shell 101, a sealing groove 106 is provided on the top of the lower shell 101, a sealing strip 107 is movably connected inside the sealing groove 106, the sealing strip 107 is fixedly connected to the upper shell 102, a sealing ring 108 is threadedly connected to the front end of the lower shell 101 and the upper shell 102, the sealing ring 108 is threadedly connected to the lens protective cover 103, and a limit ring 109 is fixedly connected to the outer surface of the lower shell 101, the upper shell 102 and the lens protective cover 103.

[0037] When the upper shell 102 is placed on top of the lower shell 101, the sealing strip 107 can be directly inserted into the sealing groove 106. At this time, the sealing strip 107 and the sealing groove 106 cooperate to ensure the sealing performance at the connection between the upper shell 102 and the lower shell 101. After the connection between the upper shell 102 and the lower shell 101 is completed, the sealing ring 108 is rotated so that the sealing ring 108 contacts the limiting ring 109 provided on the outer surface of the lower shell 101 and the upper shell 102. At this time, the sealing ring 108 can seal the connection between the upper shell 102 and the lens protective cover 103. In summary, the lower shell 101, the upper shell 102 and the lens protective cover 103 cooperate to protect the camera 2, and the overall sealing performance is guaranteed after the three are connected.

[0038] In one embodiment, the storage component 3 includes a connecting frame 301, which is fixedly installed at the rear end of the lower shell 101, and a storage box 302 is fixedly installed on one side of the connecting frame 301.

[0039] The weight of the water inside the storage box 302 and the buoyancy generated by the weight change can be transmitted to the lower shell 101 through the connecting frame 301. In this design, the connecting frame 301 isolates the weight adjustment function from the protective structure, so that the protective part of the device is not affected at all when adjusting the amount of water in the storage box.

[0040] In one embodiment, the extrusion assembly 4 includes an extrusion screw 401, which is rotatably connected to a storage box 302. An extrusion plate 402 is threadedly connected to the outer surface of the extrusion screw 401. The extrusion plate 402 is movably connected to the storage box 302. A guide rod 403 is fixedly connected inside the storage box 302. The extrusion plate 402 is movably connected to the guide rod 403. The top end of the extrusion screw 401 extends to the outside of the storage box 302 and is fixedly connected to a control disk 404.

[0041] The extrusion screw 401 can be rotated via the control panel 404. At this time, the extrusion plate 402 can move downward under the drive of the extrusion screw 401 and the guidance of the guide rod 403. The downward-moving extrusion plate 402 can squeeze the water inside the storage box 302, so that the water can be discharged from the inside of the storage box 302. The extrusion screw 401 is rotatably connected to the storage box 302 through the bearing, and rubber pads are provided on the upper and lower sides of the bearing. The rubber pads are connected to the extrusion screw 401. With the seal of the two rubber pads, external water is not easy to seep into the bearing, and thus it is also prevented that external water will seep into the inside of the storage box 302 through this point.

[0042] In one embodiment, the sealing assembly 5 includes a tapered groove 501, which is formed at the bottom of the inner wall of the storage box 302. A tapered plug 502 is fitted onto the inner wall of the tapered groove 501. A mounting bracket 503 is fixedly connected to the bottom of the storage box 302. An adjusting screw 504 is threadedly connected to the bottom of the mounting bracket 503. The top end of the adjusting screw 504 passes through the mounting bracket 503 and is fixedly connected to the bottom of the tapered plug 502.

[0043] When adjusting the weight of the storage box 302, the adjusting screw 504 is rotated. The rotating adjusting screw 504 can move on the mounting bracket 503. At this time, the conical plug 502 can move out of the conical groove 501 under the pushing action of the adjusting screw 504. This allows the water to be discharged from the storage box 302 through the conical groove 501 when the squeezing plate 402 squeezes the water inside the storage box 302. After the weight of the storage box 302 is adjusted to a suitable level, the adjusting screw 504 is rotated in the opposite direction, allowing the conical plug 502 to move back into the conical groove 501. The conical plug 502 prevents water inside the storage box 302 from continuously seeping to the top of the squeezing plate 402 under the action of external water pressure during underwater photography, thus avoiding changes in the weight of the storage box 302.

[0044] Furthermore, in specific applications, the surfaces of the adjusting screw 504, the pressing screw 401, and the connecting bolt 105 are all treated with a hot-dip galvanizing process to form a dense zinc protective layer. This coating, through the cathodic protection mechanism of the sacrificial anode, can continuously protect the internal substrate from corrosion even in the event of localized damage, thereby significantly improving the corrosion resistance of the parts in seawater environments.

[0045] In one embodiment, for the storage box 302, a discharge pipe 6 is fixedly connected to the top of the storage box 302, a sealing cap 7 is threadedly connected to the outer surface of the discharge pipe 6, and a handle 8 is fixedly connected between the lower shell 101 and the storage box 302.

[0046] Water will inevitably seep into the upper side of the extrusion plate 402. When this happens, the operator can open the sealing cover 7 and let the water on the upper side of the extrusion plate 402 drain out through the drain pipe 6. This setting can effectively prevent the water on the upper side of the extrusion plate 402 from accumulating more and more. The lower shell 101 and the storage box 302 can be supported by the handle 8.

[0047] Through the above technical solution, 1. By opening the sealing component 5 and driving the squeezing component 4, the water in the receiving component 3 can be discharged through the sealing component 5 under the squeezing action; when the weight of the receiving component 3 is adjusted to a suitable value, the operation of the squeezing component 4 is stopped, and the sealing component 5 is closed again; the above setting allows the overall weight of the device to be adjusted according to different water depths, thereby realizing adaptive control of buoyancy, effectively avoiding the need for operators to continuously adjust the magnitude and direction of the applied force, and also significantly reducing the complexity and difficulty of operation; 2. When the upper shell 102 is placed on top of the lower shell 101, the sealing strip 107 is inserted into the sealing groove 106 as the upper shell is pressed down; then the connecting bolt 105 is rotated to tightly connect the upper shell 102 and the lower shell 101 through the connecting plates 104 on both sides; finally, the sealing ring 108 is rotated to tightly cover the connection between the upper shell and the lens protective cover 103, achieving a reliable seal. The above assembly process is simple to operate, effectively ensuring the ease of installation of the camera 2 inside the lower shell 101, upper shell 102 and lens protective cover 103, and ensuring good sealing performance at the connection of the three.
