Description
Technical Field
The invention relates to a monitor, in particular to a spherical monitor.
Background
The monitor is widely applied to various industries, can assist a traffic department in managing road traffic, can help an enterprise to manage a factory, know the operation of a production line in time, and can help an individual to monitor the condition of a house and ensure the safety of the house; in order to ensure the monitoring range of the monitor, the monitor is mostly arranged at a higher position, which is inconvenient for cleaning; during daily use, dust in the air is accumulated on the surface of the protective cover, and the definition of the monitor is easily influenced; more seriously, the sealing degree of the monitor is not enough, and fog or frost is easily generated inside the protective cover due to water vapor and the like in the long-term use process, so that the visual field of the monitor is fuzzy and grey, and the monitoring effect is seriously influenced; if say that the outside dust of protective housing is clean easily relatively, the steam, fog, the frost of protective housing internal surface will be difficult to clear away, and the dismouting is then more loaded down with trivial details again, and influences normal use.
Disclosure of Invention
Aiming at the problems, the invention provides the high-definition spherical monitor which can effectively remove dust and water vapor on the inner surface and the outer surface of the protective shell without being detached, prolong the maintenance period and effectively improve the definition of the monitor.
In order to solve the problems, the technical scheme adopted by the invention is as follows: the high-definition spherical monitor comprises an organism, a camera and a protective shell, wherein the protective shell is made of a hemispherical transparent material; the protective shell is covered outside the camera,
an annular sliding groove is formed in the inner annular wall of the round edge of the protective shell, an annular bulge matched with the annular sliding groove is formed in the machine body, and the protective shell is detachably assembled on the machine body through the matched annular sliding groove and the matched annular bulge;
the outer ring wall of the protective shell is provided with transmission teeth,
the machine body is provided with a driving motor which is electrically connected with the controller and the power supply; a driving gear is arranged on a driving shaft of the driving motor and is in meshed contact with the transmission teeth on the protective shell;
the protective shell is made of a hemispherical base material with equal thickness, a circular groove is formed in the inner cavity wall of the hemispherical base material, the central axes of the groove and the hemispherical base material are collinear, and the depth of the groove is larger the closer to the central axis; transparent cleaning liquid is injected into the protective shell;
and a liquid level monitoring column is also arranged on the central shaft of the groove and is electrically connected with the controller.
The invention has the beneficial effects that: the camera freely rotates in the protective shell and monitors surrounding conditions, and light rays penetrate through the protective shell and then enter the camera to form images; in the normal working process of the camera, the driving motor drives the protective shell to rotate through the driving gear, the annular chute slides relative to the annular bulge, and the protective shell directionally rotates at a constant speed around the central shaft of the protective shell; in the rotating process of the protective shell, the cleaning solution in the groove is spread and diffused along the inner cavity wall under the action of centrifugal force, so that a liquid film is formed in the groove, the rotating liquid film can continuously wash the inner cavity wall of the protective shell, and then the water vapor and mist layer on the liquid film can be eliminated, so that the inner cavity wall of the protective shell is ensured to be clean;
the liquid level monitoring column arranged on the central shaft of the groove can monitor the thickness of a liquid film formed by cleaning liquid in the groove in real time, when the sum of the thickness of the liquid film and the thickness on the central shaft of the protective shell is equal to the thickness of the round edge of the protective shell, the liquid level monitoring column transmits a position signal to the controller, and the controller adjusts the driving motor to stop accelerating the driving gear, so that the driving gear is maintained to rotate at a constant speed, and the liquid film is maintained in a fixed shape; the liquid film that the rotatory formation of cleaning solution can supply just in the recess this moment to make liquid film and protective housing form the transparent protective layer of hemisphere type of equidistance, can effectively reduce the distortion of picture when light printing opacity protective housing, thereby guarantee the picture quality.
In addition, as the protective shell is in continuous rotation motion, large-particle dust adhered to the outer surface of the protective shell cannot block the view of the same place for a long time; therefore, in the actual shooting video of the monitor, the uneven large-particle dust distributed on the outer surface of the protective shell only flashes periodically in the screen, and the video is in a clear state for a longer time; meanwhile, due to the phenomenon of vision persistence of human eyes, although the particles of the dust moving fast on the outer surface of the protective shell are large, normal shooting and monitoring cannot be influenced in the invention.
In conclusion, in the invention, the outer surface of the protective shell is easy to contact dust, dust or large-particle dust, but the protective shell is in a fast rotating state, so that the influence of the dust on the image shot by the camera can be greatly reduced; the inner surface of the protective shell is not easy to contact with dust, but can generate a large amount of water vapor due to temperature difference, air tightness and the like, and the cleaning solution can effectively eliminate the water vapor and effectively avoid the atomization inside the protective shell; therefore, compared with the traditional monitor, the invention has better effects of removing fog and dust under the condition of ensuring the image quality, thereby improving the definition of the image; the high-definition shooting of the camera can be kept for a longer time, the maintenance period of the monitor is effectively prolonged, and the monitoring quality is improved.
Preferably, the liquid level detection column comprises a supporting rod which is collinear with the central shaft of the protective shell, a contact induction sheet which extends along the axial direction is arranged on the surface of the supporting rod, and the contact induction sheet is electrically connected with the controller; when the liquid level submerges the contact induction sheet, the corresponding contact induction sheet transmits a signal to the controller; when the liquid level reaches the critical height, the controller adjusts the driving motor to work at a constant speed; the structure enables the controller to monitor the thickness of the liquid film formed by the regulating liquid in real time, so that the controller can conveniently regulate the rotating speed; the liquid film that the conditioning fluid formed can supply the sunken of recess department for the thickness of protective housing everywhere tends to the same, and the light refraction degree everywhere is close when light passes, thereby effectively reduces the distortion of picture.
Preferably, the cleaning solution is purified water.
Preferably, a cleaning strip is arranged outside the protective shell, two ends of the cleaning strip are fixed on the machine body, and a cleaning surface of the cleaning strip is in contact with the outer surface of the protective shell; the structure can wipe the outer surface of the protective shell in the rotating process of the protective shell, so that the protective shell is further cleaned.
