Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1-2, an outdoor antifog dust protected surveillance camera head, includes fixed plate 1, and surveillance camera head 5 is installed to the lower extreme of fixed plate 1, and clearance groove 2 has been seted up to the lateral wall of fixed plate 1, and the equal fixedly connected with cleaning brush 3 of two relative inner walls in clearance groove 2, monitoring camera head 5 is installed at one side edge of fixed plate 1, and cleaning brush 3 is close to one side of transparent section of thick bamboo 4 and is made the arc. The cleaning groove 2 is rotatably connected with a transparent cylinder 4, the side wall of the transparent cylinder 4 is provided with an annular groove 6, and a driving device for driving the transparent cylinder 4 to rotate is arranged in the annular groove 6.
The annular groove 6 is internally connected with sliding plugs 7 in a sealing and sliding way, every two adjacent sliding plugs 7 are elastically connected through a spring, a plurality of guide pipes 10 communicated with the annular groove 6 are arranged in the transparent cylinder 4, and the guide pipes 10 are arranged between the two adjacent sliding plugs 7. The driving device comprises a plurality of electromagnets 8 which are slidably connected in the annular groove 6, specifically, the electromagnets 8 are iron-core-free copper solenoid type electromagnets which cannot attract the energized electromagnets 8 when not energized, and besides, like magnetic poles of adjacent groups of electromagnets 8 are opposite to each other, and magnetic repulsion force can be generated when energized.
The electromagnet 8 is fixedly connected to the side wall of the adjacent sliding plug 7, a plurality of thermoelectric generation pieces 9 electrically connected with the electromagnet 8 are embedded on the transparent cylinder 4, and the electromagnet 8 controls the on-off of the internal current through the temperature sensitive resistor.
It should be noted that, by controlling the on-off of the internal current of the electromagnet 8 with the temperature sensitive resistor, only the electromagnet 8 close to the monitoring camera 5 has a higher temperature to conduct the internal current, so that only one group of electromagnets 8 close to the monitoring camera 5 is in the on state, and the rest electromagnets 8 are in the off state.
This device is in the use, because surveillance camera head 5 can produce a large amount of heats at the during operation, leads to temperature in the transparent cylinder 4 higher, and the temperature is lower relatively outside the transparent cylinder 4, so can make the 9 both ends of thermoelectric generation piece produce the difference in temperature and then produce the electric current and supply power to electro-magnet 8.
As shown in fig. 1, the temperature close to the monitoring camera 5 is high, so the temperature of the two electromagnets 8 adjacent to the monitoring camera 5 is high, when the temperature rises to the threshold value of the internal temperature sensitive resistor, the internal circuits of the two electromagnets 8 adjacent to the monitoring camera 5 are switched on, and the two sliding plugs 7 are pulled to be away from each other (refer to fig. 1) due to the opposite magnetic poles of the two electromagnets 8, so that the overall center of gravity of the transparent cylinder 4 is shifted, so the transparent cylinder 4 rotates under the action of gravity (taking fig. 1 as an example, the sliding plugs 7 and the electromagnets 8 on the left side of the transparent cylinder 4 are sparsely distributed, and the right side of the transparent cylinder 4 is densely distributed, so the right side of the transparent cylinder 4 rotates counterclockwise). After the transparent cylinder 4 rotates, the other group of electromagnets 8 approach the monitoring camera 5 and are heated to electrify the group of electromagnets 8, the transparent cylinder 4 can be pushed to continue to rotate for a certain angle, for the electromagnets 8 away from the monitoring camera 5, when the temperature drops to the threshold value of the temperature-sensitive resistor, the power is cut off immediately, the springs can pull the two sliding plugs 7 and the electromagnets 8 to move back and reset, and the circulation is carried out, so that the transparent cylinder 4 can slowly rotate in the cleaning groove 2 in a circulating manner. Two cleaning brushes 3 in the cleaning groove 2 can clean the inside and outside of the transparent cylinder 4 synchronously, remove water mist and dust attached to the inside and outside of the transparent cylinder 4, and keep the good light transmission effect of the transparent cylinder 4, so that the definition of images shot by the monitoring camera 5 is improved. And through utilizing the inside and outside difference in temperature of camera to produce the electric energy, its energy derives from the produced heat of camera during operation, so still can improve the thermal speed of giving off of camera, can effectively cool down the processing to surveillance camera head 5, prevents that the heat from piling up and producing high temperature.
It is worth mentioning that when a certain group of electromagnets 8 is powered off, the spring can pull the two sliding plugs 7 and the electromagnets 8 to move back and return, so that air between the two sliding plugs 7 can be blown out through the conduit 10, and evaporation of water mist on the inner wall of the transparent cylinder 4 is accelerated.
Example two:
referring to fig. 3-4, the difference from the first embodiment is that a sliding groove 11 is formed in a side wall of the fixing plate 1, a plunger 12 is connected to the sliding groove 11 in a sealing and sliding manner, the plunger 12 is elastically connected to an inner wall of the sliding groove 11 through a conductive spring 13, a plurality of through holes 14 are formed in the inner wall of the sliding groove 11, the cleaning brush 3 is made of a porous sponge material, the through holes 14 are formed in an inner wall of the sliding groove 11, which is close to the cleaning brush 3, the conductive spring 13 is electrically connected to the thermoelectric generation piece 9, specifically, the conductive spring 13 is electrically connected to the thermoelectric generation piece 9 through a thyristor, so that the conductive spring 13 is intermittently energized, and further, the prior art in the electrical field is omitted.
It should be noted that, referring to fig. 4, the through hole 14 is a wedge-shaped hole with a downward inclined direction, so that the airflow blown out from the through hole 14 is inclined downward, and the inclined angle of the through hole 14 is larger than the tangential angle of the transparent cylinder 4 below, so that the dust blown off from the cleaning brush 3 is prevented from being reattached to the outer wall of the transparent cylinder 4.
In this example, the current generated by the thermoelectric generation element 9 can intermittently energize the conductive spring 13, and each time the conductive spring 13 is energized, the conductive spring 13 can contract, thus pulling the plunger 12 to move toward the cleaning brush 3, and when the conductive spring 13 is de-energized, the plunger 12 can be pushed to move back and return under the self-elastic force. So will make conducting spring 13 constantly stretch out and draw plug 12 reciprocating motion back and forth to constantly will blow through-hole 14 to the cleaning brush 3 of clearance transparent section of thick bamboo 4 outer wall dust, because cleaning brush 3 adopts porous sponge material, the air that consequently blows out can be followed cleaning brush 3 and outwards discharged, and will adhere to the dust on cleaning brush 3 and blow down, so can keep cleaning brush 3's cleanliness factor, make cleaning brush 3 can clean the outer wall of transparent section of thick bamboo 4 for a long time.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
