Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1-3, a gradually-adjusting self-cleaning infrared monitor comprises a cylindrical housing 1 and a monitor 2, the monitor 2 is mounted at the lower half part of the housing 1, i.e. the monitor 2 is mounted at a position below the axis of the housing 1, the center of the housing 1 is coaxially and rotatably connected with a rotating drum 3, the front end side wall of the rotating drum 3 is fixedly connected with a filter plate 31, the filter plate 31 is formed by splicing a plurality of sector plates with sequentially increasing filter intensity, and the filter intensity of the infrared rays of the plurality of sector plates is sequentially increased along the arrow direction of fig. 2, specifically, the infrared rays can be filtered by pasting an infrared film on the sector plates, and each sector plate can realize different filter intensities by pasting infrared films with different layers, and in an initial state, the sector plate corresponding to the monitor 2 is a transparent plate, in addition, the joint of each sector plate is subjected to transition treatment, so that when the filter plate 31 rotates, the light is more moderate, and obvious cliff type switching is avoided.
An arc-shaped cavity 4 is arranged in the side wall of the shell 1, one end of the arc-shaped cavity 4 is sealed, the other end of the arc-shaped cavity 4 is communicated with a pressure stabilizing channel 5, an arc-shaped friction strip 41 is connected in the arc-shaped cavity 4 in a sliding and sealing mode, expansion liquid 42 is filled between the arc-shaped friction strip 41 and the sealed end of the arc-shaped cavity 4, it is required to be explained that a heat conducting block (copper can be adopted as the heat conducting block) is embedded in the position, corresponding to the expansion liquid 41, of the shell 1, the heat conduction between the external environment temperature and the expansion liquid 41 can be increased, specifically, the expansion liquid 42 is one of mercury or kerosene, when the temperature rises, the mercury or the kerosene is heated to expand, a slot communicated with the arc-shaped cavity 4 is formed in the upper side wall of the shell 1, a friction wheel 6 is connected in the shell 1 in a rotating mode, the friction wheel 6 is provided with a rubber ring along the circumferential direction for improving the friction coefficient.
The working principle of the embodiment is as follows:
in the initial state of the implementation, the monitoring head 2 corresponds to the transparent position of the filter plate 31, the expansion liquid 42 is heated and expanded along with the irradiation of strong sunlight from the outside, the expansion liquid 42 pushes the arc-shaped friction strip 41 to move along the arc-shaped cavity 4, the arc-shaped cavity 4 drives the rotary drum 3 to rotate through the friction wheel 6, the rotary drum 3 drives the filter plate 31 to rotate, the stronger the sunlight is, the higher the thermal expansion degree of the expansion liquid 42 is, namely the larger the amplitude of the rotation of the filter plate 31 is, so that the adjustment of the filtering intensity of the filter plate 31 can be realized according to the strong degree of the sunlight, compared with the cliff type adjustment of the traditional infrared switcher, the accuracy is higher, the switching process is softer, and the better imaging effect is realized; at night, the temperature gradually decreases, and the expansion liquid 42 contracts to reset the arc-shaped rubbing strip 41, so as to drive the filter plate 31 to reset.
