Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification equipment, in particular to a visual dehumidification device for an optical shield. Background Art

[0002] The main function of the optical cover is to protect the optical device from damage by external objects and the influence of water vapor and dust, ensuring that the optical device maintains a high degree of precision and clarity during operation. In high-precision optical equipment such as lasers and infrared thermal imaging, the role of the optical cover is particularly important, as it can effectively extend the service life of the equipment and improve the stability and reliability of the equipment.

[0003] In order to prevent the electrical components inside the optical cover from being corroded by water vapor and to prevent water vapor condensation on the optical window, a desiccant needs to be set inside the optical cover to remove the water vapor retained inside the optical cover and ensure the dryness of the inside of the optical cover.

[0004] At present, optical cover desiccants are all installed by directly fixing them inside the optical cover, but there are the following problems. First, the inside of the optical cover is a closed space, and the life of the desiccant inside the optical cover cannot be observed at any time; second, when replacing the desiccant, the optical cover needs to be disassembled, which is a lot of work; finally, after the optical cover is disassembled, the risk of the internal components of the optical cover contacting the external environment is increased, which easily leads to a large amount of dust and water vapor from the external environment entering. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a visual dehumidification device for an optical shield, which can observe the life of a desiccant inside a box body in real time through a glass cover, thereby preventing the desiccant in the optical shield from being replaced in time, thereby causing water vapor to remain inside the optical shield. The device is simple, efficient, safe and reliable.

[0006] The utility model is realized by the following technical scheme, and provides a visual dehumidification device for an optical shield, wherein a mounting hole is provided on the optical shield; the utility model comprises a box body which is arranged in the optical shield through the mounting hole, a vent hole is provided on the box body, and the inner cavity of the box body is connected to the inner cavity of the optical shield through the vent hole; an observation port is provided on one side of the box body close to the mounting hole, and a glass cover covering the observation port is provided on the mounting hole; the life of the desiccant in the box body is observed in real time through the glass cover, so as to avoid the desiccant in the optical shield from being unable to be replaced in time, thereby causing water vapor to remain in the optical shield.

[0007] As an optimization, a pressing plate is provided on the side of the glass cover away from the box body, and an observation hole corresponding to the observation port is opened on the pressing plate; a screw hole is opened on the box body, and a through hole corresponding to the screw hole is opened on the pressing plate, and the pressing plate fixes the glass cover to the box body by screws passing through the through hole and the screw hole in sequence; the glass cover is fixed to the box body by the pressing plate, which is convenient for loading and unloading of the glass cover, thereby facilitating the replacement of the desiccant in the box body.

[0008] As an optimization, an upper sealing ring is provided between the glass cover and the box body, and the upper sealing ring extends around the observation port; a lower sealing ring is provided between the box body and the optical shield, and the lower sealing ring extends around the mounting hole; the upper sealing ring and the lower sealing ring ensure that the optical shield is in a sealed state to prevent external dust or water vapor from entering the optical shield.

[0009] The beneficial effects of the utility model are as follows: the life of the desiccant inside the box body can be observed in real time through the glass cover, so that the desiccant in the optical cover cannot be replaced in time, which causes water vapor to remain inside the optical cover; the glass cover is fixed to the box body through the pressing plate, which is convenient for loading and unloading the glass cover, thereby facilitating the replacement of the desiccant in the box body; the optical cover is ensured to be in a sealed state through the upper sealing ring and the lower sealing ring, so as to prevent external dust or water vapor from entering the optical cover.
