[0001] The utility model relates to the technical field of laser rulers, in particular to an integrated laser ruler for a full-sea-depth manned submersible. Background Art

[0002] "The deep sea holds treasures far beyond our understanding and exploration. However, to access these treasures, we must master key technologies in deep-sea access, exploration, and development." Manned submersibles offer significant technical advantages in deep-sea access and exploration, and are a crucial means for humanity to develop and utilize the deep sea. They can quickly and accurately transport scientists, engineers, and various devices and specialized equipment to complex deep-sea environments, enabling efficient exploration, scientific investigation, and development operations.

[0003] (1) Existing technical solutions

[0004] During deep-sea operations, the key to deep-sea operations is for divers to quickly and effectively determine the target size. However, due to factors such as the lack of seabed reference objects and the deviation of the underwater viewing angle, it is impossible to give a precise target size. Currently, there is no laser ruler suitable for full ocean depth on the market. Chinese patent CN113008211A discloses a compact laser ruler for underwater use that can achieve the function of target size determination, but it needs to be used in pairs and installed in parallel; this compact laser ruler adopts the structure of an integrally encapsulated normal pressure laser, and the full ocean depth pressure is a huge test for the front-end glass.

[0005] (2) Disadvantages of existing technical solutions

[0006] The compact laser ruler disclosed in Chinese patent CN113008211A cannot be expanded to apply to the full ocean depth and cannot meet the pressure requirements; its paired working mode requires the submersible to provide two power supply interfaces, and increases the risk of leakage or insulation of full-ocean-depth manned submersibles; its parallel installation method requires the submersible to provide suitable mounting brackets and space, and increases the difficulty of maintenance, making it inconvenient for daily use and disassembly.

[0007] Therefore, the present invention proposes an integrated laser ruler for full-sea-depth manned submersibles, which has the ability to withstand full-sea-depth pressure, has a compact structure, and a convenient interface, and can significantly improve the operating efficiency of manned submersibles.

[0032] Example:

[0033] like Figures 1 to 3 As shown, the utility model provides an integrated laser ruler for a full-sea-depth manned submersible, comprising:

[0034] The pressure-resistant cabin 1 has a first guide groove 11 and a second guide groove 12 formed on its side end;

[0035] A watertight connector 2, detachably connected to one end of the pressure-resistant cabin 1;

[0036] The laser diodes 3 are disposed in the first guide groove 11 and the second guide groove 12, so that the two laser diodes 3 are axially positioned by the first guide groove 11 and the second guide groove 12; the laser diodes 3 are electrically connected to the watertight connector 2; a soft interference fit is formed between the laser diodes 3 and the two guide grooves, and the friction force thereof prevents the laser diodes 3 from rotating within the two guide grooves;

[0037] The end cap 4 is detachably connected to the first guide groove 11 and the second guide groove 12;

[0038] A light-transmitting sheet 5 is provided inside the end cap 4 to allow the laser to pass through;

[0039] The watertight plug 6 is detachably connected to the other end of the pressure-resistant cabin 1 .

[0040] Furthermore, the pressure-resistant cabin 1 of the present invention has an integrated external structural design and has the ability to withstand pressure at full sea depth.

[0041] See also Figure 3 The integrated laser ruler of the present invention also includes a controller 7, which is arranged in the pressure-resistant cabin 1. The controller 7 is electrically connected to the watertight connector 2, and the laser diode 3 is connected to the controller 7 through a wire 9. The utility model is powered by a full-sea-depth manned submersible. The interface type of the watertight connector 2 is consistent with that of the manned submersible. The electric energy is transmitted to the laser diode 3 via the watertight connector 2 and the controller 7. The laser diode 3 emits a point-shaped laser beam, thereby realizing the ruler function. The input voltage of the controller 7 as a control circuit can be 24V, 12V or 5V, and the output voltage is 2.5V. For different input voltages, the input line is connected to the corresponding voltage input port to ensure the universality of the input voltage. The output voltage of the controller 7 is 2-way 2.5V, which is output to the two laser diodes 3 respectively, thereby ensuring the stable operation of the laser diode 3.

[0042] See also Figure 3 , and also includes an "O"-shaped sealing ring 8, which is respectively arranged between the light-transmitting sheet 5 and the first guide groove 11, and between the light-transmitting sheet 5 and the second guide groove 12 to achieve sealing.

[0043] See also Figure 3 The light-transmitting sheet 5 is made of ceramic glass. The ceramic glass is made of transparent ceramic with high light transmittance and has been tested by water pressure. The end cap 4 connects the ceramic glass to the pressure-resistant cabin 1 to ensure that the laser ruler can withstand the full sea depth pressure.

[0044] See also Figure 3 The end faces of the watertight connector 2 and the watertight plug 6 are provided with sealing rings to seal the two ends of the pressure-resistant cabin 1.

[0045] See also Figure 3 The outer circles of the first guide groove 11 and the second guide groove 12 are provided with external threads, and the end cap 4 is detachably threadedly connected to the first guide groove 11 and the second guide groove 12 through the external threads to facilitate disassembly.

[0049] See also Figure 3 A rubber pad is filled between the end cap 4 and the ceramic glass to reduce contact stress.

[0050] See also Figure 4 , shows the control circuit diagram of the controller 7. Specifically, the H1 plug inputs a DC24V power supply, with pins ① and ② connected to the positive side and pins ③ and ④ connected to the negative side. The voltage is stepped down to DC12V by the U1 linear power supply MC7812, and then stepped down to DC5V by the U2 linear power supply MC7805. After being stepped down by 0.7V by IN4007, a DC4.3V voltage source is obtained. Two laser diodes 3 are connected in series, with the positive end of one laser diode 3 connected to pin ① of H2 and the negative end to pin ② of H2. The positive end of the other laser diode 3 is connected to pin ③ of H2 and the negative end to pin 4 of H2, thereby meeting the power supply requirements of the two laser diodes 3.
