Description

Technical Field

[0001] This utility model relates to the field of pressure special equipment technology, specifically to an explosion-proof pan-tilt structure and an underwater pan-tilt camera. Background Technology

[0002] In the field of deep-sea exploration, underwater probes are typically equipped with pan-tilt cameras to acquire underwater images. The high-pressure environment of underwater operations requires sufficient waterproofing and sealing performance, and the lack of adequate light sources in this environment results in unclear images, necessitating supplemental lighting.

[0003] To protect the camera and prevent water damage, existing special underwater cameras typically have a transparent explosion-proof dome around the camera. In addition, supplementary lights are usually installed to supplement the light. However, the supplementary lights are usually designed around the perimeter of the camera. On the one hand, there is the problem of heat dissipation of the LEDs inside the explosion-proof dome. On the other hand, when the light from the supplementary light is emitted, some of the light is reflected by the explosion-proof dome, which causes reflections. These reflections can interfere with the camera's imaging and affect normal image formation.

[0004] To address this, we propose an explosion-proof PTZ structure and an underwater PTZ camera. Utility Model Content

[0005] This application provides an explosion-proof PTZ structure and an underwater PTZ camera to at least solve the problems of existing special cameras in the prior art, such as heat dissipation of LEDs inside the explosion-proof dome, and reflection of some of the light emitted by the supplementary light being reflected by the explosion-proof dome, which interferes with the camera's imaging and affects normal image formation.

[0006] In a first aspect, this application provides an explosion-proof pan-tilt structure, including an integral shell, which is hollow cylindrical and has a spherical cover fixedly mounted at its first end, and a bottom cover embedded at its other end; it also includes a supplementary lighting component radially fixed to the outside of the integral shell to provide supplementary lighting for video recording, the supplementary lighting component including:

[0007] The number of lamp mounting holes is several and arranged in a ring array on the radial shell of the integrated housing, and the wall of the lamp mounting holes is formed with several ring steps.

[0008] The transparent lamp housing is provided in several parts, and each part has several claws in the middle of the side near the integrated housing. The outer wall of each claw has a snap-fit ​​groove that fits with an annular step to fix the transparent lamp housing. A lamp cavity is opened in the middle of each claw.

[0009] Several infrared LED beads are disposed within the lamp cavity.

[0010] A heat sink, which is ring-shaped and disposed in the inner cavity of the integrated housing, and several infrared LEDs are fixed to the upper part of the heat sink.

[0011] Optionally, a first sealing ring is provided between the spherical cover and the integrated outer shell, and between the bottom cover and the integrated outer shell.

[0012] Optionally, a plurality of second sealing rings are embedded on the side of the transparent lamp housing near the integrated housing.

[0013] Optionally, the integrated housing has an assembly step corresponding to several of the transparent lamp housing positions, and the outer wall of the assembly step is recessed to form several slope grooves that match the transparent lamp housing.

[0014] Optionally, a gimbal bracket is provided in the inner cavity of the integrated housing, which is located in the inner cavity of the integrated housing and fixed to the bottom cover by a number of isolation copper pillars.

[0015] Optionally, the lower part of the heat sink is bent and abuts against the side of the integrated housing cavity near the bottom cover.

[0016] Secondly, this application provides an underwater pan-tilt camera, including the explosion-proof pan-tilt structure described in the first aspect, and further including...

[0017] The gimbal camera is installed inside the cavity of the explosion-proof gimbal structure, and the gimbal camera can rotate freely inside the spherical cover to take pictures from multiple angles through the spherical cover.

[0018] Optionally, an electrical interface is inserted into the bottom cover to power the gimbal camera and the fill light assembly.

[0019] Compared with related technologies, the explosion-proof pan-tilt structure and underwater pan-tilt camera provided in this application have at least the following technical advantages:

[0020] The assembly of the spherical dome, integrated housing, and bottom cover forms a sealed chamber that isolates the inside from the outside, preventing the entry of external high-pressure environment and seawater, thus effectively protecting the PTZ camera from normal imaging and free angle adjustment on the underwater detector; at the same time, the semi-embedded design of the supplementary lighting component in the radial direction of the integrated housing enables the supplementary lighting function to cooperate with the PTZ camera, and the light will not cause reflection of the spherical dome, ensuring clear imaging.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In related technologies, existing special cameras typically feature a transparent explosion-proof dome around the probe to protect it and ensure good explosion-proof protection. They also often include supplementary lighting, but these lights are usually positioned around the perimeter of the camera. This presents challenges: firstly, there's the issue of heat dissipation for the LEDs inside the dome; secondly, some of the light emitted by the supplementary light is reflected by the dome, creating glare that interferes with the camera's imaging and affects normal image capture.

[0030] Based on the above, this utility model provides an explosion-proof pan-tilt structure and an underwater pan-tilt camera, which will be described in detail below with reference to specific embodiments and accompanying drawings.

[0031] Example 1

[0032] This utility model embodiment provides an explosion-proof gimbal structure. Figure 1 This is a schematic diagram of an underwater gimbal camera structure according to an exemplary embodiment. Figure 2 This is a cross-sectional view of an underwater gimbal camera according to an exemplary embodiment. Figure 3 yes Figure 2 Enlarged schematic diagram of structure A in the middle. (See diagram below.) Figure 1-3 As shown, the explosion-proof gimbal structure includes an integrated housing 20, which is hollow cylindrical in shape and has a spherical cover 50 fixedly mounted at its first end. A bottom cover 10 is embedded at its other end. First sealing rings are provided between the spherical cover 50 and the integrated housing 20, and between the bottom cover 10 and the integrated housing 20, ensuring that after assembly, the spherical cover 50, the integrated housing 20, and the bottom cover 10 form a sealed chamber within the integrated housing 20, isolating the interior and ensuring the installation of the gimbal camera 60. Further, a gimbal bracket 70 is provided within the inner cavity of the integrated housing 20, which is fixed to the bottom cover 10 by several insulating copper pillars. It also includes a supplementary lighting assembly 30 radially fixed to the outside of the integrated housing 20 to provide supplementary lighting for the camera, comprising:

[0033] The number of lamp mounting holes is several and arranged in a ring array on the radial shell of the integral outer shell 20, and the wall of the lamp mounting holes is formed with several ring steps 306.

[0034] There are several transparent lamp housings 301, and several claws 302 are provided in the middle of the side of the transparent lamp housing 301 near the integrated outer shell 20. The annular outer wall of the claws 302 has a snap-fit ​​groove 307 that matches the annular step 306 to fix the transparent lamp housing 301. A lamp cavity 303 is opened in the middle of the several claws 302. In this embodiment, several second sealing rings are embedded in the side of the transparent lamp housing 301 near the integrated outer shell 20.

[0035] Infrared lamp beads 304, there are several of them and they are respectively disposed in the lamp cavity 303;

[0036] The heat sink 305 is ring-shaped and disposed in the inner cavity of the integrated housing 20, and several infrared LEDs 304 are fixed to the upper part of the heat sink 305.

[0037] In the above embodiment, the assembly step is to first insert the transparent lamp housing 301, and then the claw part 302 of the transparent lamp housing 301 is deformed and inserted into the lamp mounting hole until the annular step 306 and the snap-fit ​​groove 307 cooperate to snap-fit, thereby realizing the assembly and fixation of the transparent lamp housing 301.

[0038] The infrared LED 304 is fixed on the upper part of the heat sink 305 and directly installed into the inner cavity of the integrated housing 20. Then, the position of the infrared LED 304 is adjusted and it is snapped into the lamp cavity 303 to realize the installation of the supplementary lighting component 30.

[0039] Next, assemble the gimbal camera 60 onto the gimbal bracket 70, then fix the gimbal bracket 70 to the bottom cover 10, and finally install the gimbal camera 60 and the gimbal bracket 70 into the inner cavity of the integrated housing 20 and fix the bottom cover 10. Then install the spherical cover 50 to complete the assembly.

[0040] In this embodiment, after the spherical cover 50, the integrated housing 20, and the bottom cover 10 are assembled, a sealed chamber is formed inside the integrated housing 20, isolating it from the outside and preventing the ingress of external high-pressure environment and seawater. This effectively protects the gimbal camera 60 from normal imaging and free angle adjustment on the underwater detector. Based on the pressure-resistant and sealed design, it can be used at a depth of 100 meters underwater. At the same time, the supplementary lighting component 30 is semi-embedded in the radial direction of the integrated housing 20, thereby realizing the supplementary lighting function in conjunction with the gimbal camera 60. Moreover, the light will not cause reflection of the spherical cover 50, ensuring clear imaging.

[0041] In this embodiment, please continue to refer to Appendix Figure 1 The integrated housing 20 has an assembly step corresponding to several transparent lamp housings 301. The outer wall of the assembly step is recessed to form several sloping grooves that match the transparent lamp housings 301. This allows the transparent lamp housings 301 to be partially hidden relative to the recessed part of the assembly step. The sloping structure of the grooves does not obstruct the diffusion of light, effectively expanding the supplementary light and improving the image quality of the camera.

[0042] In this embodiment (not shown in the figure), in order to ensure the sealing of the chamber, the infrared lamp 304 and the heat sink 305 are both located inside the sealed integrated housing 20, where heat is not easily dissipated. Therefore, after the lower part of the heat sink 305 is bent, it abuts against the side of the integrated housing 20 near the bottom cover 10. The integrated housing 20 is made of metal, and the heat sink 305 abuts against the integrated housing 20. The heat dissipation requirement is fully considered, and heat dissipation is achieved through heat exchange between the integrated housing 20 and the water in contact.

[0043] In summary, the explosion-proof gimbal structure provided in this embodiment of the present invention, through the assembly of the spherical cover 50, the integrated housing 20, and the bottom cover 10, forms a sealed chamber that isolates the inside and outside, preventing the entry of external high-pressure environment and seawater, thereby effectively protecting the gimbal camera 60 from normal imaging and free angle adjustment on the underwater detector. Based on the pressure-resistant and sealed design, it can be used at a depth of 100 meters underwater. At the same time, the semi-embedded design of the supplementary lighting component 30 in the radial direction of the integrated housing 20 enables it to provide supplementary lighting for the gimbal camera 60, and the light will not cause reflection of the spherical cover 50, ensuring clear imaging.

[0046] The gimbal camera 60 is installed inside the explosion-proof gimbal structure cavity, and the gimbal camera 60 can rotate freely inside the spherical cover 50 to capture images from multiple angles through the spherical cover 50. The circular rotation and vertical rotation of the gimbal camera 60 are existing technologies that have been widely used in market products and can be obtained through market procurement, so they will not be described in detail here.

[0047] Furthermore, in this embodiment, an electrical interface 40 is inserted on the bottom cover 10 to supply power to the gimbal camera 60 and the supplementary lighting component 30. Several feet 101 are provided on the edge of the bottom cover 10. The feet 101 are fixed to the underwater detector by several screws, thereby realizing that the electrical interface 40 is hidden in the underwater detector mounting part and protecting the circuit safety.

[0048] Other undescribed structures are described in Example 1.

[0049] In summary, the explosion-proof gimbal structure and underwater gimbal camera provided in this embodiment of the present invention, through the assembly of the spherical cover 50, the integrated housing 20 and the bottom cover 10, form a sealed chamber that isolates the inside and outside, preventing the external high-pressure environment and seawater from entering, thereby effectively protecting the gimbal camera 60 from normal imaging and free angle adjustment on the underwater detector. Based on the pressure-resistant and sealed design, it can be used at a depth of 100 meters underwater. At the same time, the semi-embedded design of the supplementary lighting component 30 in the radial direction of the integrated housing 20 enables it to provide supplementary lighting for the gimbal camera 60, and the light will not cause reflection of the spherical cover 50, ensuring clear imaging.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
