Description

Technical Field

[0001] The utility model relates to the field of optical detection, and more specifically, to an optical instrument for detecting deformation of underwater instrument window glass. Background Art

[0002] Optical instruments have become increasingly common in recent years, particularly underwater imaging equipment. Underwater equipment often utilizes protective glass. When compressed by water pressure, this glass deforms, affecting the overall imaging quality of the device. Therefore, designing and utilizing a protective glass of sufficient strength is crucial. To more quickly and intuitively determine whether a designed protective glass meets these strength requirements, the instrument described in this invention can be used to quickly assess the compressive deformation of the protective glass.

[0003] As people continue to explore the ocean, the water pressure that underwater detection needs to withstand is getting higher and higher. When the protective glass cannot withstand extreme water pressure, it will not only cause image distortion and blur, but in severe cases it may even break, endangering the safety and function of the entire underwater camera system. Therefore, more stringent requirements are placed on the material selection, structural design and strength verification of the protective glass. Traditional methods often rely on long-term pressure testing in the laboratory, which is not only time-consuming, but also difficult to fully simulate the complex and changing underwater environment, limiting R&D efficiency and product iteration speed;

[0004] Therefore, in order to solve the above problems, an optical instrument for detecting deformation of underwater instrument window glass is proposed. Utility Model Content

[0026] Among them: specifically, the main names of the optical instrument for detecting deformation of underwater instrument window glass are light source 1, pressure chamber 2, first protective glass to be inspected 3, cage adjustment structure assembly 4, focusing lens group 5, first optical imaging assembly 6, second plano-convex lens 7, third protective glass 8, inner shell movement 9, and second optical imaging assembly 10.

[0027] Specifically, the underwater lens stress and deformation detection device is placed in deep water and uses the light source 1 to illuminate the first protective glass 3 to be inspected. At this time, other components are protected by the pressure chamber 2 and are not affected by the water pressure and remain in a dry chamber state.

[0028] Specifically, the light source 1 includes a laser fiber 11, an adjustment frame 12, a fiber sealing glass 13, and a U-shaped curved rod support frame 14. One end of the laser fiber 11 is fixed to the adjustment frame 12, and the adjustment knob of the adjustment frame 12 is used to adjust the light output position of the laser fiber 11 to correspond to the center of the first protective glass 3 to be inspected.

[0029] Specifically, the cage adjustment structure assembly 4 includes a cage structure support 15, a first cage structure adjustment frame 16, a second cage structure adjustment frame 17, a third cage structure adjustment frame 18, a fourth cage structure adjustment support frame 19, and a fifth cage structure adjustment support frame 20.

[0030] Specifically, the cage adjustment assembly 4 is adjusted by securing the first cage adjustment frame 16 with the first cage adjustment frame 15. The second cage adjustment frame 17, the third cage adjustment frame 18, the fourth cage adjustment support frame 19, and the fifth cage adjustment support frame 20 are then inserted sequentially. The cage adjustment frame 16 then slides back and forth on the cage adjustment frame 15 to adjust the distance between the support frames. Once the position is adjusted, the support frames are locked in place with screws.

[0031] Specifically, the second cage-type structure adjustment frame 17 is fixed to the third cage-type structure adjustment frame 18 via four small pillars.

[0032] Specifically, the focusing lens group 5 is fixed on the first cage structure adjustment frame 16 in the cage adjustment structure assembly 4. The distance between the focusing lens group 5 and the first inspected protective glass 3 is controlled by adjusting the front and rear positions of the first cage structure adjustment frame 16.

[0033] Specifically, the first optical imaging assembly 6 and the second plano-convex lens 7 are respectively fixed to the second cage structure adjustment frame 17 and the third cage structure adjustment frame 18 in the cage adjustment structure assembly 4. Similarly, changing the position of the second cage structure adjustment frame 17 and the third cage structure adjustment frame 18 changes the relative position of the first optical imaging assembly 6 and the second plano-convex lens 7, that is, their relative positions in the overall underwater lens stress and deformation detection device.

[0034] Specifically, the third protective glass 8 is fixed to the inner shell movement 9, forming a sealed cavity inside the inner shell movement 9. The inner shell movement 9 has a sealing ring groove in which the sealing ring protrudes. When the third protective glass 8 is fixed, the sealing ring is squeezed and fills the gap between the third protective glass 8 and the inner shell movement 9, thus sealing the cavity.

[0035] Specifically, the second optical imaging assembly 10 is composed of a first beam splitter prism 21 , a first optical camera 22 , a second beam splitter prism 23 , a reflective lens 24 , and a second optical camera 25 .

[0036] Specifically, the function of the first beam splitter prism 21 is to split the light entering the inner shell movement 9 and transmit it to the target surface of the first optical camera 22 .

[0037] Specifically, the reflective lens 24 and the second beam splitter prism 23 are used to combine the light generated by the laser optical fiber 11 into the second optical camera 25 .

[0038] Specifically, the laser optical fiber 11, the first optical camera 22, and the second optical camera 25 are powered and exchange data through a watertight joint at the tail of the underwater lens stress and deformation detection equipment.

[0039] Specifically, the principle of underwater lens stress and deformation detection is that when the light emitted by the light source 1 passes through the first inspected protective glass 3, the focusing lens group 5, the first optical imaging component 6, the second plano-convex lens 7, and the third protective glass 8, an image will be formed on the second optical camera 25. When the first inspected protective glass 3 is deformed by water pressure, the image will produce corresponding changes. The changes in the first inspected protective glass 3 can be obtained through data analysis and calculation.

[0040] The working process of this utility model is as follows:

[0041] When this underwater instrument window glass deformation detection optical instrument is in use, the light output position of the laser fiber 11 is adjusted by the adjustment frame 12 to make it accurately correspond to the center of the first protective glass 3 to be inspected, and the cage adjustment structure component 4 adjusts the position of the focusing lens group 5, the first optical imaging component 6 and the second plano-convex lens 7. The front and rear distances and relative positions of these components are adjusted by sliding and fixing each support frame on the cage structure pillar 15. The focusing lens group 5 is fixed on the first cage structure adjustment frame 16, and its position is adjusted to control the distance between it and the first protective glass 3 to be inspected. The first optical imaging component 6 and the second plano-convex lens 7 are respectively fixed on the second cage structure adjustment frame 17 and the third cage structure adjustment frame 18. Their relative positions are changed by adjusting the positions of these frames. The third protective glass 8 is fixed on the inner shell movement 9 and is realized by a sealing ring. It is now sealed to protect the internal components from the influence of water. When the light emitted by the light source 1 passes through the first inspected protective glass 3, the focusing lens group 5, the first optical imaging component 6, the second plano-convex lens 7 and the third protective glass 8, the light will be split inside the inner shell movement 9. The first beam splitter prism 21 transmits the light to the target surface of the first optical camera 22 for imaging. At the same time, the reflective lens 24 and the second beam splitter prism 23 combine the light generated by the laser fiber 11 into the second optical camera 25 for imaging. The laser fiber 11, the first optical camera 22 and the second optical camera 25 are powered and exchange data through a watertight joint. When the first inspected protective glass 3 is deformed by water pressure, the image imaged by the second optical camera 25 will change accordingly. Through data analysis and calculation, the deformation of the first inspected protective glass 3 can be obtained. This is the working process and working principle of the device.
