Description

Technical Field

[0001] The invention relates to the technical field of photoelectric sensors, and in particular to an infrared light beam dynamic tracking and positioning device. Background Art

[0002] The infrared beam dynamic tracking and positioning device is a device that uses infrared beams to track and locate the target object or the motion trajectory of the object. The working principle is based on the emission, reflection and reception process of infrared light. By calculating the spatial position and motion trajectory of the target object relative to the sensor, accurate dynamic tracking and positioning are achieved. This device is usually used in application scenarios that require high-precision position detection, such as virtual reality, robot navigation, motion capture, drone control, and security monitoring. Using an infrared beam dynamic tracking and positioning device on a construction site can help achieve high-precision measurement and positioning, such as for robot navigation, precise positioning of buildings, and path planning for material handling.

[0003] However, the special conditions in the construction site environment make the use of such devices face many challenges, especially the influence of dust and the difficulty of maintenance. Infrared beams need a clear propagation path to work effectively, and the construction site environment is usually full of dust. Dust particles absorb or scatter infrared light, causing signal attenuation or interference, which affects the positioning accuracy and the normal operation of the system. In order to keep the equipment running properly, dust needs to be cleaned regularly, especially the optical components. This is a big challenge on the construction site, and the surface of the optical components is easily scratched due to the adhesion of fine quartz stones during the cleaning process. It is very inconvenient to use.

[0004] Therefore, an infrared beam dynamic tracking and positioning device is proposed to solve the above-mentioned problems. Summary of the invention

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides an infrared beam dynamic tracking and positioning device, which has the following beneficial effects:

[0022] 1. The infrared beam dynamic tracking and positioning device uses a continuous dust removal mechanism to turn on the drive motor, so that the air enters the air outlet through the pipe, so that the gas enters the annular protection frame and is discharged outward. At this time, the air is blown out from the inner wall of the annular protection frame, and the right side of the annular protection frame is closed by the machine body. The air will form a certain positive pressure inside the annular protection frame. This positive pressure can effectively prevent external dust from entering the pipe. The air continuously flows into the annular protection frame and maintains a positive pressure state. A protective barrier will be formed inside the annular protection frame to prevent dust from entering, which plays a role in continuous dust prevention during use and is convenient to use.

[0023] 2. The infrared beam dynamic tracking and positioning device is set up with an optical device protection mechanism. When the transmission shaft rotates, the transmission shaft drives the main shaft to rotate through the belt, and the main shaft drives the driving gear to rotate. The driving gear drives the rack plate meshing with it to move upward. At this time, the return spring is compressed and stored, and the rack plate drives the driven shaft to rotate, and the driven shaft drives the protective cover to rotate half a circle. At this time, the smooth part of the rack plate is opposite to the driving gear. At this time, the driving gear cannot drive the rack plate to continue to move upward, so that the driven gear, the driven shaft and the protective cover no longer rotate. At this time, the left side of the annular protective frame is opened, air can pass through, and the machine body can also work normally. When the machine body stops working, the drive motor is turned off. At this time, the return spring drives the rack plate to move downward, and the rack plate drives the driven gear to rotate half a circle in the opposite direction, so that the driven gear drives the driven shaft and the protective cover to rotate half a circle in the opposite direction. At this time, the protective cover covers the left side of the annular protective frame to prevent dust from entering when the device is not in use, thereby further playing a role in dustproof protection.

[0024] 3. The infrared beam dynamic tracking and positioning device is set by a filtering mechanism. When the driving motor is turned on, the rack plate drives the sealing plate to move upward until the sealing plate is located at the upper part of the air inlet. At this time, the outside air can enter the air inlet through the cavity between the connecting frame and the protective shell, and then enter the inner wall of the protective shell. The filter screen plays a role in preventing dust from entering. When the driving motor is turned off, it can be seen from the above that the rack plate moves downward, and the rack plate drives the sealing plate to move downward, so that the sealing plate moves to the lower part of the air inlet, preventing the outside dust and impurities from entering the protective shell through the air inlet. At the same time, the sealing plate compresses the air in the cavity and drives the air to be discharged through the bottom filter screen. When the air passes through the filter screen, a certain pressure difference will be generated. This pressure difference can help remove dust particles stuck in the pores of the filter screen. It plays a role in cleaning the filter screen 53, preventing the filter screen 53 from being blocked by dust, causing poor air entry, thereby further affecting the positive pressure state in the annular protective frame 34, and further improving the dust prevention effect.

[0025] 4. The infrared beam dynamic tracking and positioning device uses a continuous dust removal mechanism. The output shaft of the driving motor drives the transmission shaft to rotate, and the transmission shaft drives the fan blades to rotate, so that the air flows toward the machine body, which plays a role in heat dissipation for the machine body.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-7 , an infrared beam dynamic tracking and positioning device, comprising a body 1, a protective shell 2 is fixedly connected to the body 1, a continuous dust removal mechanism 3 is arranged on the inner wall of the protective shell 2, and the continuous dust removal mechanism 3 comprises a driving motor 31; the output shaft of the driving motor 31 is fixedly connected to a transmission shaft 32, and the end of the transmission shaft 32 away from the driving motor 31 is fixedly connected to a fan blade 33, and the left side of the protective shell 2 is fixedly connected to an annular protection frame 34, and the inner wall of the annular protection frame 34 is fixedly connected to a pipe 35, and the outer wall of the pipe 35 is fixedly connected to an air outlet 36; an optical device protection mechanism 4 is arranged on the inner wall and the outer wall of the protective shell 2, and a filtering mechanism 5 is arranged on the inner wall and the outer wall of the protective shell 2. When in use, the driving motor 31 is turned on, the output shaft of the driving motor 31 drives the transmission shaft 32 to rotate, and the transmission shaft 32 drives the fan blade 33 to rotate, so that the air flows in the direction of the body 1, and at this time, the air enters the air outlet 36 through the pipe 35, so that the gas enters the annular protection frame 34, and the air will form a certain positive pressure inside the annular protection frame 34. Air continuously flows into the annular protection frame 34 and maintains a positive pressure state, so that a protective barrier is formed inside the annular protection frame 34 to prevent dust from entering.

[0036] The optical device protection mechanism 4 includes a main shaft 41, which is connected to the transmission shaft 32 through a belt 43. A driving gear 42 is fixedly connected to the outer wall of the main shaft 41, and a driven shaft 44 is rotatably connected to the inner wall of the annular protection frame 34. A driven gear 45 is fixedly connected to one end of the driven shaft 44, and a protective cover 46 is fixedly connected to the other end of the driven shaft 44. One end of a return spring 47 is fixedly connected to the inner wall of the protective shell 2, and a rack plate 48 is fixedly connected to the other end of the return spring 47. When the body 1 stops working, the return spring 47 drives the rack plate 48 to move downward, and the rack plate 48 drives the driven gear 45 to rotate half a circle in the opposite direction, so that the driven gear 45 drives the driven shaft 44 and the protective cover 46 to rotate half a circle in the opposite direction. At this time, the protective cover 46 covers the left side of the annular protection frame 34 to prevent dust from entering when the device is not in use. The filter screen 53 serves to prevent dust from entering. When the drive motor 31 is turned off, the return spring 47 drives the rack plate 48 to move downward, and the rack plate 48 drives the sealing plate 54 to move downward, so that the sealing plate 54 moves to the lower part of the air inlet 52 to prevent external dust and impurities from entering the protective shell 2 through the air inlet 52. At the same time, the sealing plate 54 will compress the air in the cavity, driving the air to be discharged through the filter screen 53 at the bottom. When the air passes through the filter screen 53, a certain pressure difference will be generated. This pressure difference can help remove dust particles stuck in the pores of the filter screen 53.

[0037] The filter mechanism 5 includes a connection frame 51, a filter screen 53 is fixedly connected to the inner wall of the connection frame 51, an air inlet 52 is opened on the outer wall of the protective shell 2, and a sealing plate 54 is fixedly connected to the outer wall of the rack plate 48.

[0038] The inner wall of the annular protection frame 34 is fixed to the outer wall of the body 1, and the left side of the annular protection frame 34 is an opening. The body 1 is located on the inner wall of the annular protection frame 34, so that when a collision occurs, the annular protection frame 34 can collide with an external object first, which plays a role in protecting the body 1. One end of the pipe 35 is connected to the inner wall of the protective shell 2, and the other end of the pipe 35 is connected to the air outlet 36, and the air outlet 36 is a truncated cone. The smooth surface and gradual structure of the truncated cone air outlet 36 help to reduce the resistance of the air flow and reduce the formation of turbulence. This can not only improve the efficiency of the system, but also reduce noise. The air blown by the fan blades 33 is discharged through the pipe 35 and the air outlet 36. The truncated cone air outlet 36 helps to evenly diffuse the air flow to the surrounding space, so that the inner wall of the annular protection frame 34 forms a stable positive pressure, and can effectively suppress the backflow phenomenon of the air flow, ensuring that the gas flows in a predetermined direction. This is very important for ensuring the normal operation of the ventilation system and preventing air pollutants from entering the clean area.

[0039] The main shaft 41 is rotatably connected to the inner wall of the protective shell 2. The main shaft 41 rotates stably, and the outer wall of the rack plate 48 is slidably connected to the inner wall of the protective shell 2. The rack plate 48 can slide up and down stably, and a smooth part is provided on the front of the rack plate 48. After the active gear 42 drives the rack plate 48 to move upward for a certain distance, the active gear 42 and the rack of the rack plate 48 are no longer engaged, the outer wall of the protective shell 2 is fixedly connected to the outer wall of the connecting frame 51, the bottom of the connecting frame 51 is connected to the outside, the outer wall of the sealing plate 54 is piston-connected to the inner wall of the connecting frame 51, and the outer wall of the sealing plate 54 is slidably connected to the inner wall of the protective shell 2. The inner wall of the connecting frame 51 forms a cavity with an empty bottom on the right side of the outer wall of the protective shell 2, and the cavity is piston-connected to the outer wall of the sealing plate 54, and a sliding groove is provided on the right side of the outer wall of the protective shell 2, so that the connecting piece on the left side of the sealing plate 54 can slide up and down stably, which is convenient for the rack plate 48 to drive the sealing plate 54 to slide up and down.

[0040] The body 1 appearing in this article is an infrared beam dynamic tracking and positioning device. The device is based on the emission, reflection and reception process of infrared light, and achieves accurate dynamic tracking and positioning by calculating the spatial position and motion trajectory of the target object relative to the sensor. It is a prior art and will not be described in detail in this specification.

[0041] Working principle: when the machine body 1 is working, the drive motor 31 is turned on, the output shaft of the drive motor 31 drives the transmission shaft 32 to rotate, and the transmission shaft 32 drives the fan blades 33 to rotate, so that the air flows in the direction of the machine body 1, which has a cooling effect on the machine body 1, and at this time, the air enters the air outlet 36 through the pipe 35, so that the gas enters the annular protection frame 34 and is discharged outward. At this time, the air is blown out from the inner wall of the annular protection frame 34, and the right side of the annular protection frame 34 is closed by the machine body 1, and the air will form a certain positive pressure inside the annular protection frame 34. This positive pressure can effectively prevent external dust from entering the pipe 35, and the air continuously enters the annular protection frame 34 and flows and maintains a positive pressure state. A protective barrier will be formed inside the annular protection frame 34 to prevent dust from entering, which plays a role of continuous dust prevention during use and is convenient to use.

[0042] When the transmission shaft 32 rotates, the transmission shaft 32 drives the main shaft 41 to rotate through the belt 43, the main shaft 41 drives the driving gear 42 to rotate, and the driving gear 42 drives the rack plate 48 meshing therewith to move upward. At this time, the return spring 47 is compressed and stored, and the rack plate 48 drives the driven shaft 44 to rotate, and the driven shaft 44 drives the protective cover 46 to rotate half a circle. At this time, the smooth part of the rack plate 48 is opposite to the driving gear 42. At this time, the driving gear 42 cannot drive the rack plate 48 to continue to move upward, so that the driven gear 45, the driven shaft 44 and the protective cover 46 are 6 no longer rotates, at this time the left side of the annular protection frame 34 is opened, air can pass through, and the body 1 can also work normally. When the body 1 stops working, the drive motor 31 is turned off, and the return spring 47 drives the rack plate 48 to move downward, and the rack plate 48 drives the driven gear 45 to rotate half a circle in the opposite direction, so that the driven gear 45 drives the driven shaft 44 and the protective cover 46 to rotate half a circle in the opposite direction. At this time, the protective cover 46 covers the left side of the annular protection frame 34 to prevent dust from entering when the device is not in use, thereby further playing a role in dust protection.

[0043] When the drive motor 31 is turned on, it can be seen from the above that the rack plate 48 moves upward. At this time, the rack plate 48 drives the sealing plate 54 to move upward until the sealing plate 54 is located at the upper part of the air inlet 52. At this time, the outside air can enter the air inlet 52 through the cavity between the connecting frame 51 and the protective shell 2, and then enter the inner wall of the protective shell 2. The filter screen 53 plays a role in preventing dust from entering. When the drive motor 31 is turned off, it can be seen from the above that the rack plate 48 moves downward. The rack plate 48 drives the sealing plate 54 to move downward, so that the sealing plate 54 moves to the lower part of the air inlet 52 to prevent external dust and impurities from entering the protective shell 2 through the air inlet 52. At the same time, the sealing plate 54 will compress the air in the cavity, driving the air to be discharged through the filter screen 53 at the bottom. When the air passes through the filter screen 53, a certain pressure difference will be generated. This pressure difference can help remove dust particles stuck in the pores of the filter screen 53. It plays the role of cleaning the filter 53, preventing the filter 53 from being blocked by dust, causing poor air entry, and further affecting the positive pressure state in the annular protection frame 34, further improving the dustproof effect.

[0044] In summary, the infrared light beam dynamic tracking and positioning device can solve the problem of needing to regularly clean the dust on the surface of the optical element of the infrared light beam dynamic tracking and positioning device in a construction site environment.
