Description

Technical Field

[0001] The utility model belongs to the technical field of laser communication, and particularly relates to a laser communication transmitter alignment device. Background Technique

[0002] A laser communication transmitter is an important communication device. It uses a laser beam as an information carrier to directly perform two-way transmission of information such as voice, data, and images in space. The working principle of the laser communication transmitter is based on the process of optical amplification, mainly including three key steps: excitation, amplification, and optical output. When excitation energy is added to the laser medium, the excited electrons will transition from a low energy level to a high energy level, forming an excited state with an energy difference. Subsequently, through the stimulated emission process in light, the excited state electrons transition back to the low energy level and release a beam of photons with the same energy as the stimulated emission process. These photons are amplified in the optical resonator and concentrated in the same wavelength, phase, and direction. Finally, through the action of optical devices such as mirrors or gratings, a collimated, monochromatic, and highly coherent laser beam is formed and output. And the laser communication transmitter needs to be aligned with the receiving end to complete signal transmission, so a laser communication transmitter alignment device is required.

[0003] However, there are some problems in the existing technology: the existing laser communication transmitter alignment device usually uses a tripod to fix the laser communication transmitter, and then continuously adjusts the position of the tripod to align with the receiving end. However, this alignment device requires manual lifting of the tripod to adjust the position and then putting it down. It often needs to be repeatedly lifted and put down many times to align the laser communication transmitter with the receiving end, which is very troublesome and easily causes the laser communication transmitter to be knocked or dropped, resulting in damage to the laser communication transmitter. Therefore, we propose a laser communication transmitter alignment device. Content of the Utility Model

[0004] Aiming at the problems existing in the existing technology, the purpose of the utility model is to provide a laser communication transmitter alignment device, which adjusts the position of the laser communication transmitter through an adjustment structure, so as to avoid the need to frequently move the tripod for adjustment and prevent the laser communication transmitter from being knocked or dropped, resulting in damage to the laser communication transmitter.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 6 shown, an alignment device for a laser communication transmitter provided by an embodiment of the present utility model includes a base 1. The base 1 is rectangular and made of stainless steel. The main function of the base 1 is to support the laser communication transmitter.

[0025] A regulating seat 2 is slidably connected to the base 1, and a regulating component 3 is arranged inside the base 1. The regulating component 3 is used to drive the regulating seat 2 to slide. The regulating component 3 includes a threaded rod 301. A chute is opened at the upper end of the base 1, and the threaded rod 301 is rotatably connected in the chute. One end of the threaded rod 301 is fixedly connected with a regulating knob 302.

[0026] The regulating seat 2 is slidably connected in the chute of the base 1. A threaded hole is opened in the middle of the regulating seat 2, and the threaded rod 301 is threadedly connected in the threaded hole. The threaded rod 301 is used to drive the regulating seat 2 to slide.

[0027] Rotate the regulating knob 302. The regulating knob 302 drives the threaded rod 301 to rotate. After the threaded rod 301 rotates, it will drive the regulating seat 2 to slide in the chute on the base 1, so that the laser communication transmitter moves, and the horizontal position of the laser communication transmitter is adjusted.

[0028] A rotating groove is opened at the upper end of the regulating seat 2, and a bracket 4 is rotatably connected in the rotating groove. A locking component 5 is arranged on the regulating seat 2. The locking component 5 is used to limit the rotation of the bracket 4. The locking component 5 includes a rotating shaft 501. The rotating shaft 501 is fixedly connected to the upper end of the regulating seat 2. A first fixing member 502 and a second fixing member 503 are rotatably connected to the rotating shaft 501. The first fixing member 502 and the second fixing member 503 are arranged in an alternating manner. Rubber rings are arranged on the first fixing member 502 and the second fixing member 503 to strengthen the friction between the first fixing member 502 and the second fixing member 503 and the bracket 4, avoiding the deviation of the bracket 4 and at the same time reducing the friction loss between the first fixing member 502 and the second fixing member 503 and the bracket 4, and extending the service life of the present utility model.

[0029] A fixing block 504 is rotatably connected to the first fixing member 502. Sliding grooves are opened on both sides of the fixing block 504, and a clamping block 505 is slidably connected in the sliding grooves. A limiting groove is opened on the second fixing member 503, and a clamping groove is opened on the inner wall of the limiting groove. The clamping block 505 is clamped in the clamping groove.

[0030] The inner wall of the slideway of the fixed block 504 is fixedly connected with a first spring 506. The first spring 506 is fixedly connected to the clamping block 505. The fixed block 504 is provided with a locking groove. A second spring 507 is fixedly connected in the locking groove. The second spring 507 is fixedly connected with a push block 508. One end of the push block 508 is fixedly connected with a button 509. The push block 508 is used to push the clamping block 505.

[0031] Press the button 509 to make the push block 508 stretch the second spring 507 and move inward, so that the clamping block 505 no longer receives the thrust of the push block 508. It will contract due to the resilience of the first spring 506, so that the clamping block 505 is retracted into the slideway. After the fixed block 504 tightens the first fixing member 502 and the second fixing member 503, release the button 509, and the push block 508 will retract due to the resilience of the second spring 507, thereby pushing the clamping block 505 to stretch the first spring 506 and move outward of the slideway, so that the clamping block 505 is clamped in the card slot to tighten and fix the first fixing member 502 and the second fixing member 503, avoiding the need to recalibrate due to the offset of the laser communication transmitter.

[0032] A transmitter body 6 is rotatably connected to the bracket 4. An adjusting rod 8 is fixedly connected to the outer wall of the transmitter body 6. The adjusting rod 8 is rotatably connected to the bracket 4. One end of the adjusting rod 8 is fixedly connected with a knob 11. A fixing groove is provided on one side of the bracket 4. A clamping seat 9 is slidably connected to the fixing groove. The clamping seat 9 is also provided with a rubber ring to strengthen the friction between the clamping seat 9 and the adjusting rod 8, avoiding the offset of the adjusting rod 8 while reducing the frictional loss between the clamping seat 9 and the adjusting rod 8, and extending the service life of the present utility model. A groove is provided on one side of the clamping seat 9. A fixing screw 10 is rotatably connected in the groove. The fixing screw 10 is threadedly connected in the fixing groove.

[0033] After loosening the fixing screw 10, the clamping seat 9 no longer locks the adjusting rod 8. At this time, rotate the knob 11, and the knob 11 drives the adjusting rod 8 to rotate, so that the transmitter body 6 rotates to adjust the position of the laser communication transmitter in the vertical direction. After the adjustment is completed, tighten the fixing screw 10, and the clamping seat 9 will clamp the adjusting rod 8 again.

[0034] The lower end of the base 1 is fixedly connected with a tripod 7, and the tripod 7 is used to support the whole device.

[0035] The working principle of the present utility model is as follows:

[0036] The utility model can first place the tripod 7 at the initial alignment position of the laser communication transmitter and the receiving end, then adjust the horizontal position of the laser communication transmitter by rotating the adjustment knob 302, then adjust the direction of the laser communication transmitter by rotating the bracket 4, and finally adjust the vertical position of the laser communication transmitter by rotating the knob 11, so as to quickly adjust the emission position of the laser communication transmitter, enabling the receiving end to better receive information. There is no need for staff to frequently lift and lower the tripod 7 for adjustment, avoiding damage to the laser communication transmitter caused by bumping or dropping it.

[0037] After adjusting the direction of the laser communication transmitter, the utility model clamps the first fixing member 502 and the second fixing member 503 on the surface of the bracket 4, then presses the button 509 to retract the latch 505 into the slideway, and then rotates the fixing block 504 to tighten the first fixing member 502 and the second fixing member 503. Then, release the button 509. At this time, the latch 505 just engages in the card slot to lock the first fixing member 502 and the second fixing member 503, thus fixing the bracket 4. At the same time, after adjusting the vertical position of the laser communication transmitter, by rotating the fixing screw 10, the clamping seat 9 can clamp the adjusting rod 8. Compared with the existing method of only tightening with the fixing screw 10, the utility model can be fixed more firmly after adjusting the laser communication emission angle, avoiding the need for recalibration due to deviation during the use of the laser communication emission.

[0038] The description of the above embodiments is only used to help understand the method and its core idea of the utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the utility model, several improvements and modifications can be made to the utility model, and these improvements and modifications also fall within the protection scope of the claims of the utility model.
