Description
Technical Field
The utility model relates to a myopia prevention device, in particular to the technical field of a myopia prevention auxiliary device for workers in submarine environments.
Background
At present, china is the country with the largest global myopia population. In submarine environments, the damage to the eyesight of submarine workers has become a non-negligible problem due to the fact that the workers are in a closed environment for a long time and operate underwater for a long time. The problem of vision damage of submarine personnel in a closed environment is solved from the viewpoints of eye and physical and mental health. It was found by investigation that the refractive error detection rate (70.11%) of the conventional submarine personnel was significantly higher than that of the surface warship group (57.34%). Meanwhile, for the people with low vision, the symptoms of blurred vision, eye soreness, dryness, foreign body sensation, even dizziness, head distension and other asthenopia often appear in work.
In addition to being in a submarine cabin environment, submarines often view video terminals (including electronic instrument screens, computers, mobile phones and the like) in short distance for a long time, and visual fatigue and myopia degree are deepened in the long time. In addition, most myopic submarines refuse to wear eyes because of worry about affecting training work or worrying about wearing glasses to aggravate myopia degrees, and thus rely on self-adjustment for a long time, further causing tiredness of ciliary muscles to aggravate, and further causing the degree to deepen. Therefore, it is important to prevent myopia and asthenopia of the personnel in submarine environment.
Disclosure of Invention
The utility model aims to solve the problems and provide a device for preventing myopia of submarine staff.
Because the space is very narrow under the submarine environment, the daily environment field of vision of the staff is narrow, and the visual fatigue and myopia are deepened in the long term, the technical thought for solving the problem is to increase the visual field range of the staff through specular reflection, so that the staff can look out and relax ciliary muscles in the narrow space.
The technical scheme for solving the technical problems is as follows: the device for preventing myopia of the staff in the submarine environment comprises a bottom plate and a device body, wherein the device body is fixed on the bottom plate;
the device body comprises a front side surface, a left side surface, a right side surface, a rear side surface and a top surface; the front side surface is one-way light-transmitting mirror glass, and the mirror surface of the one-way light-transmitting mirror glass faces the inside of the device; the unidirectional light-transmitting mirror glass has the characteristics of scratch resistance and corrosion resistance and has good perspective.
The inner surface of the rear side surface is provided with a reflecting mirror; the inner surface of the top surface is stuck with blue wallpaper; the upper surface of the bottom plate is stuck with green wallpaper; the inner surfaces of the left side surface and the right side surface are stuck with blue-green gradual change wallpaper which changes from blue to green from top to bottom; the sky green color was simulated.
4 warm look lamp strips (LED light strip) are provided with at 4 corners that top surface, left surface, right flank and bottom plate formed, and device body surface is provided with the lamp strip switch.
Further, the size of the unidirectional light-transmitting mirror glass on the front side is 40 multiplied by 40cm; the size of the reflector on the rear side is 40 multiplied by 40cm; the left side surface, the right side surface and the top surface are 100 multiplied by 40cm in size; the size of the bottom plate is 100X 50cm.
A user stands outside the unidirectional lens, can observe the inside of the device by opening the switch, and can relax eyes by staring outside 20m. The mirror surface of the outer wall unidirectional light-transmitting mirror glass faces the inside of the device, and a user can stand outside the device to see the internal environment of the device through the unidirectional light-transmitting mirror glass.
Further, the bottom plate is provided with the sticky wooden ladder board of ladder figurative visual target in the upper surface of device body coverage, the crossbeam on the sticky wooden ladder board of visual target is used for pasting different visual targets. The ornamental value is increased.
Furthermore, because the submarine has a narrow environment, the requirements on safety and stability of the device are high, and anti-collision silica gel is arranged at each edge of the device. Preventing and treating collision.
Further, in order to prevent jolt of the underwater working device, a clamping plate for fixing the base plate to the table top is also provided. Preventing the device from slipping.
Further, a label attached to the ground for guiding the placement of the foot of the user is also provided.
The utility model provides a device for preventing myopia of submarine staff, which has the following beneficial effects:
according to the utility model, the LED lamplight and structural virtual images such as blue sky green space, visual marks and the like in the device are infinitely reflected between the two mirrors through the reflecting mirror surface and the unidirectional perspective mirror surface glass, and a far virtual image is manufactured in a narrow space, so that relaxation of ciliary muscles of observers is facilitated. According to the principle of specular reflection, standing inside the observation device behind the half mirror, when the 9 th virtual image in the opposite mirror is observed, if the distance between the opposite mirrors is 1m, the observed virtual image is more than 20m from the observer's eye distance. Although specular reflection has a loss of light energy, more than 10 virtual images may be reflected. In the working process of submarine personnel, the space inside a cabin is quite narrow, long-term detection of a fixation instrument screen is required, ciliary muscle tension is easily caused, peripheral retina hyperopia is caused to be out of focus, and myopia degree is increased. According to the ophthalmic 20-20-20 principle, the eye is held at near distance for 20 minutes, and it is necessary to gaze at an external object 20s of 20 feet (6 meters) for visual relaxation. And the remote annotation relaxation rest is difficult to be carried out at any time in the submarine, and the eye relaxation environment with the distance of more than 20m is not available. Through the myopia prevention device, a user can gaze the sight at an object virtual image as far as possible, so that the vision relaxation rest is realized in a narrow space, and the purpose of myopia prevention is achieved.
