Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the embodiments of the present invention, it should be noted that the terms "first", "second" and "third" are used for the sake of clarity in describing the numbering of the components of the product and do not represent any substantial difference, unless explicitly stated or limited otherwise. The directions of "up", "down", "left" and "right" are all based on the directions shown in the attached drawings. Specific meanings of the above terms in the embodiments of the present invention can be understood by those of ordinary skill in the art according to specific situations.

It is to be understood that, unless otherwise expressly specified or limited, the term "coupled" is used broadly, and may, for example, refer to directly coupled devices or indirectly coupled devices through intervening media. The specific meaning of the above terms in the embodiments of the present invention can be understood in specific cases by those skilled in the art.

The camera cleaning device provided by the embodiment comprises a host and an air ring connected with the host through a PU (polyurethane) hose 3, as shown in fig. 1, the host comprises a micro inflator pump 22, a one-way valve 23 and an air storage tank 24 which are sequentially connected, the air storage tank 24 is connected with the air ring through the PU hose 3, an air filter 21 is further arranged, one end of the air filter is communicated with outside air, the other end of the air filter is connected with the micro inflator pump 22, an electromagnetic pulse valve 27 is arranged between the air storage tank 24 and the air ring, an MCU (microprogrammed control unit) main control board 28 for controlling the micro inflator pump 22, the air storage tank 24 and the electromagnetic pulse valve 27 is further arranged in the host, the air storage tank 24 is further provided with a pressure gauge 25 and a safety valve 26, and the MCU main control board 28 controls the micro inflator pump 22 to be started and stopped according to a pressure signal of the pressure gauge 25; the wind ring comprises a bottom ring 11 and an upper cover 12, the outer edge of the bottom ring 11 is fixed with the outer edge of the upper cover 12, and a gap with a certain angle is reserved between the inclined planes of the inner edges of the bottom ring 11 and the upper cover, so that a circular seam is formed. An adjusting base 4 for installing a wind ring is further arranged below the camera.

The working principle is as follows: when the MCU main board in the host computer detects that the set cleaning period is reached, the MCU main board is switched from a dormant state to a working state, the micro inflator pump 22 is started, the inflator pump conveys compressed air to the air storage tank 24 through the one-way valve 23, the air pressure in the air storage tank 24 is gradually increased, and when the upper limit pressure (about 2.5bar) of the pressure gauge 25 is reached, the micro inflator pump 22 stops working. After proper time delay, the MCU opens the pulse valve to reach the set pulse width, and then immediately closes the pulse valve to generate pulse airflow, the pulse airflow sweeps the front end glass of the camera through the air ring, the reciprocating operation is carried out, and after the set sweeping times are reached, the host enters the dormant state again until the next sweeping period comes. During purging, if the pressure in the air storage tank 24 is lower than the lower limit pressure of the electric contact pressure gauge 25, the MCU commands the purging stop, and the micro inflator 22 operates again to compensate for the pressure loss in the air storage tank 24. And after the pressure is normal, restarting the purging process until the set purging frequency is reached.

Through the operation panel on the host computer, the cleaning cycle can be set up in a flexible way. If necessary, the purge can be forced manually by a panel button. The intermittent pulse air flow purging is beneficial to pressure recovery in the air storage tank 24, so that the cleaning effect is better than that of continuous purging, the power of the whole system is less than 200W, the whole system is in a dormant state for most of time, and the energy consumption is lower.

The wind ring structure is shown in figure 3: the outer edge of the bottom ring 11 and the outer edge of the upper cover 12 are fixed by continuous welding, and a gap with a certain angle is left between the inclined planes of the inner edges of the bottom ring and the upper cover to form a circular seam. High-speed pulse airflow enters a cavity formed by the bottom ring 11 and the upper cover 12 through the air inlet 13 and is blown out along the annular gap, and the camera glass is cleaned. The central hole of the air inlet 13 is aligned with the small hole on the outer wall surface of the bottom ring 11 and welded together. The upper cover 12 is bonded with a nitrile rubber pad 14 with a certain thickness and used for preventing the wind ring from damaging the lens glass of the camera when the wind ring vibrates accidentally.

According to different use occasions and different shapes of the camera, the wind ring can be in a circular shape, a square shape, an irregular polygon shape or other shapes so as to achieve the best blowing effect.

The camera cleaning device of this embodiment utilizes the high-speed pulse air current that comes out from the wind ring to sweep the adnexed dust above the lens glass repeatedly to the centre all around, can reach the clean effect of ideal and long-term the use can not lead to the fact the fish tail to lens glass, is applicable to the dust more, to the surveillance camera head definition requirement higher, difficult artifical occasion of directly clearing up. The problem of the camera inconvenient clearance has effectually been solved.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
