Description

Technical Field

[0001] This utility model relates to the technical field of anti-fouling and cleaning devices, specifically an anti-fouling and cleaning device for optical lenses of spectral instruments. Background Technology

[0002] Spectroscopic instruments measure the intensity distribution of radiant energy within different wavelength ranges to obtain the radiation spectrum, and then calculate key radiance parameters such as irradiance and radiance. They have wide applications in many fields, such as industrial hazardous gases, safety monitoring of flammable and explosive gases, and atmospheric environmental monitoring. Optical sensors based on tunable laser absorption spectroscopy technology have the advantages of high precision, high selectivity, and non-contact long-distance, large-scale remote sensing.

[0003] The traditional method of manually wiping the surface of optical lenses with alcohol-soaked lint-free cotton swabs is extremely inefficient and cannot meet the needs of mass production. At the same time, due to their high-gloss mirror surface, they are prone to dust accumulation, scratches, and have low surface hardness, so they cannot be wiped clean casually, otherwise physical damage can easily be caused.

[0004] In view of this, we propose a device for cleaning and preventing contamination of optical lenses in spectral instruments. Utility Model Content

[0005] The purpose of this invention is to provide a device for cleaning and preventing contamination of optical lenses in spectral instruments, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for preventing contamination and cleaning optical lenses of spectroscopic instruments includes a base, a bracket fixedly mounted on the base, a lens body snapped into the bracket, and a cleaning mechanism provided on the base. The cleaning mechanism includes:

[0008] An asynchronous motor is fixedly mounted on the base. A rotating rod is fixedly mounted on the output end of the asynchronous motor. One end of the rotating rod is rotatably mounted inside the bracket through a bearing component. A first support plate is fixedly mounted on the outer wall of the rotating rod.

[0009] An air pump is fixedly installed at the top of the first support plate. The air pump outlet is fixedly installed at one end of the air outlet pipe, and the other end of the air outlet pipe is fixedly installed inside the top of the conical cover. A baffle is fixedly installed on the inner wall of the conical cover. The outer wall of the conical cover is fixedly installed on the outer wall of the rectangular plate. The outer wall of the top of the rectangular plate is fixedly installed at the bottom of the first support plate. The arc-shaped side wall of the conical cover is attached to the outer wall of the lens body. A drain port is opened at the bottom of the conical cover.

[0010] A gas collection box is fixedly installed on the top of the first support plate. An air pump inlet is fixedly installed inside one side of the gas collection box. An air inlet pipe is fixedly installed inside the top of the gas collection box. A dry sponge is snapped into the air inlet pipe. An ethanol bottle is fixedly installed on the top of the first support plate. A water pump inlet is fixedly installed inside one side of the ethanol bottle. The water pump is fixedly installed on the top of the first support plate. The water pump outlet is fixedly installed at one end of a mist nozzle. The other end of the mist nozzle is fixedly installed inside the other side of the gas collection box.

[0011] In a further embodiment, the baffle is installed at an angle inside the conical cover.

[0012] In a further embodiment, the side of the cone-shaped cover with the larger diameter is fitted to the lens body.

[0013] In a further embodiment, the dry sponge has through-holes inside.

[0014] In a further embodiment, an auxiliary mechanism is provided on the rotating rod. The auxiliary mechanism includes a second support plate, a sewage box is fixedly installed on the top of the second support plate, one end of a sewage pipe is fixedly installed inside the side wall of the sewage box, a flow guide is fixedly installed inside the sewage pipe, the other end of the sewage pipe is fixedly installed at the bottom of the manifold, and the top of the manifold is fixedly installed inside the bottom of the conical cover.

[0015] In a further embodiment, the air deflector is provided in multiple sets.

[0016] In a further embodiment, the manifold is tapered.

[0017] Compared with the prior art, this utility model provides a device for preventing and cleaning contamination of optical lenses in spectral instruments, which has the following beneficial effects:

[0018] 1. This anti-fouling and cleaning device for optical lenses of spectroscopic instruments, in order to achieve a highly efficient cleaning effect on the lens body, is equipped with a cleaning mechanism. An asynchronous motor drives a rotating rod to rotate, which in turn drives the first support plate to rotate, so that the conical cover tightly fits the outer wall of the lens body and rotates synchronously. At the same time, after the air pump is started, outside air is drawn into the air collection box through the air inlet pipe. The air undergoes preliminary filtration when passing through a dry sponge. Ethanol in the ethanol bottle is drawn by a water pump and mixed into the air in the air collection box in the form of fine droplets through a mist nozzle, forming a mixed gas with a cleaning effect. This mixed gas is delivered to the conical cover through the air outlet pipe and sprayed onto the lens surface at an appropriate angle under the guidance of the inclined baffle, effectively removing stubborn stains.

[0019] 2. This anti-fouling and cleaning device for optical lenses of spectroscopic instruments is designed to effectively collect and discharge dirt and waste liquid generated during the cleaning process. By setting up an auxiliary mechanism, when waste liquid and impurities flow out from the drain port at the bottom of the conical cover, the manifold uses its conical structure to accelerate the liquid flow. In conjunction with multiple sets of guide hoods evenly distributed inside the drain pipe, it ensures that the liquid flows smoothly into the drain box, avoiding backflow and residue, and achieving efficient and coordinated operation of cleaning and sewage discharge.

Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A device for preventing contamination and cleaning optical lenses of spectral instruments includes a base 1, a bracket 2 fixedly installed on the base 1, and a lens body 3 snapped into the bracket 2.

[0033] In one embodiment of this utility model, a cleaning mechanism 4 is provided on the base 1. The cleaning mechanism 4 includes an asynchronous motor 41. The asynchronous motor 41 is fixedly installed on the base 1. A rotating rod 42 is fixedly installed at the output end of the asynchronous motor 41. One end of the rotating rod 42 is rotatably installed inside the bracket 2 through a bearing. A first support plate 43 is fixedly installed on the outer wall of the rotating rod 42. An air pump 44 is fixedly installed at the top of the first support plate 43. The air outlet end of the air pump 44 is fixedly installed at one end of an air outlet pipe 45. The other end of the air outlet pipe 45 is fixedly installed inside the top of a conical cover 46. A baffle 48 is fixedly installed on the inner wall of the conical cover 46. The baffle 48 is installed obliquely inside the conical cover 46. The outer wall of the conical cover 46 is fixedly installed on the outer wall of a rectangular plate 47. The top outer wall of the rectangular plate 47 is fixedly installed on the bottom end of the first support plate 43. The conical cover 46 is arc-shaped. The sidewall is attached to the outer wall of the lens body 3. The larger diameter side of the conical cover 46 is attached to the lens body 3. A drain port 49 is provided at the bottom of the conical cover 46. A gas collection box 410 is fixedly installed at the top of the first support plate 43. The air pump 44 is fixedly installed inside one side of the gas collection box 410. An air inlet pipe 411 is fixedly installed inside the top of the gas collection box 410. A dry sponge 412 is snapped into the air inlet pipe 411. The dry sponge 412 has a through hole inside. An ethanol bottle 413 is fixedly installed at the top of the first support plate 43. The water pump 414 is fixedly installed at the water inlet of the water pump 414 inside one side of the ethanol bottle 413. The water pump 414 is fixedly installed at the top of the first support plate 43. The water outlet of the water pump 414 is fixedly installed at one end of the mist nozzle 415. The other end of the mist nozzle 415 is fixedly installed inside the other side of the gas collection box 410.

[0034] In this embodiment, after the device is started, the asynchronous motor 41 begins to run, and its output end drives the rotating rod 42 to rotate at a stable speed. When the rotating rod 42 rotates, the first support plate 43 fixed to its outer wall rotates synchronously. The rotation of the first support plate 43 drives the rectangular plate 47 at the bottom to move, thereby causing the conical cover 46 fixed to the outer wall of the rectangular plate 47 to rotate along the outer wall of the lens body 3, ensuring that the conical cover 46 can cover all areas of the lens body 3. At the same time, the air pump 44 starts, generating suction to draw outside air into the air collection box 410 through the air inlet pipe 411. When the air flows through the dry sponge 412 inside the air inlet pipe 411, the through holes inside the dry sponge 412 will adsorb dust and other impurities in the air, performing preliminary purification of the air. While pump 44 is working, water pump 414 starts to extract ethanol from ethanol bottle 413. The ethanol is then transported by water pump 414 to mist nozzle 415, which atomizes the ethanol into fine droplets and sprays them into gas collection box 410. The atomized ethanol mixes thoroughly with the air filtered by dry sponge 412 in gas collection box 410 to form a mixed gas with cleaning capabilities. Air pump 44 pressurizes the mixed gas in gas collection box 410 into outlet pipe 45. The mixed gas enters conical hood 46 through outlet pipe 45. Under the obstruction and guidance of inclined baffle 48, the mixed gas entering conical hood 46 changes its flow direction and is sprayed onto lens body 3 at an angle that is closer to the surface of lens body 3, thus rinsing and cleaning the stains on the surface of lens body 3.

[0035] In one embodiment of this utility model, an auxiliary mechanism 5 is provided on the rotating rod 42. The auxiliary mechanism 5 includes a second support plate 51. A sewage box 52 is fixedly installed on the top of the second support plate 51. One end of a sewage pipe 53 is fixedly installed inside the side wall of the sewage box 52. A guide shroud 54 is fixedly installed inside the sewage pipe 53. Multiple guide shrouds 54 are provided. The other end of the sewage pipe 53 is fixedly installed at the bottom of the manifold 55. The manifold 55 is conical in shape. The top end of the manifold 55 is fixedly installed inside the bottom of the conical cover 46.

[0036] In this embodiment, the dirt-laden gas generated during the cleaning process is discharged from the drain port 49 at the bottom of the conical cover 46. At this time, the auxiliary mechanism 5 starts to function. The dirt-laden gas first enters the manifold 55. The conical structure of the manifold 55 guides the gas flow. Subsequently, the gas enters the drain pipe 53 through the manifold 55. Multiple sets of evenly distributed guide covers 54 are fixedly installed inside the drain pipe 53. These guide covers 54 can prevent gas from converging and avoid dirt from returning to the lens due to turbulent gas flow. They play a good guiding and diversion role for the gas. Under the combined action of the manifold 55 and the guide covers 54, the dirt-laden gas can flow smoothly into the drain box 52, realizing the efficient and coordinated operation of cleaning and draining.
