In the prior art, application number is CN201720552638.5, and technical scheme name is a patent application file of automatically cleaning type cloud platform structure, discloses one kind and has self-cleaning function, including arc elasticity brush-holder stud and two motors that drive the motion of arc elasticity brush-holder stud, the motor is as the power unit of dust on the clean camera lens of arc elasticity brush-holder stud. The application number is CN202121487428.5, and technical scheme name is an inspection unmanned aerial vehicle's with infrared imaging lens self-cleaning function patent application file, discloses one kind and has self-cleaning function, including clean motor, rotor plate, the cotton technical scheme of cleaning, clean motor is rotatory through the drive rotor plate, changes the relative position of clean cotton and camera lens. Application number is CN202210051725.8, and technical scheme name ground disaster cruise unmanned aerial vehicle safety compels to fall the patent application file of device, discloses a technical scheme including clean cotton, hydrojet portion, the power source of clean cotton is the motor, the power source of hydrojet portion is the pump. The technical scheme is used for solving the problem of cleaning the camera lens in the flight process of the unmanned aerial vehicle, and the self-cleaning mechanisms in the unmanned aerial vehicle are respectively provided with an independent motor; for solutions involving clean fluids, it is necessary for the drone to carry clean water, configure special pumps for the fluids, etc.
Corresponding with above prior art, this scheme provides a steady image cloud platform including automatically cleaning mechanism, lies in with prior art's difference: through set up at the particular position and clean the pad, utilize the necessary every single move motor on the cloud platform to solve the camera lens and clean the contact problem of pad, like this, can needn't set up special motor for automatically cleaning mechanism again, when reaching the clean purpose of camera lens, can reduce unmanned aerial vehicle machine and carry weight, be favorable to prolonging unmanned aerial vehicle's time of endurance, increase the mileage of endurance, promote unmanned aerial vehicle's flight performance.
More in detail, in the scheme, the pitching motor shaft is the axis of the pitching motor rotor, and the axis of the arc plate and the axis of the pitching motor shaft are collinear, so that after the camera is rotatably installed on the roll arm through the pitching motor shaft, the distance of the lens relative to the axis and the position of the lens on the axis are controlled, the lens can be contacted with the wiping pad installed on the sunken side when rotating upwards, and the dust attached to the lens can be wiped through the relative motion between the lens and the wiping pad, so that the image stabilizing holder has a self-cleaning function. Above in-process, carry out relevant clean action and can accomplish under every single move motor's action, for prior art, because every single move motor generally is the essential equipment on the cloud platform, need not set up special motor for wiping the pad work promptly, so this scheme can effectively alleviate unmanned aerial vehicle's the weight of carrying on. The arc-shaped plate is fixed on the transverse rolling arm, so that the course action and the transverse rolling action of the cradle head do not influence the action of the wiping pad on the lens, and the lens is downward in normal aerial photography, so that the self-cleaning mechanism does not influence the normal shooting of the camera. Through setting up the arc for carrying on and cleaning the pad simultaneously through injecing corresponding axis relation, under the little condition of arc weight, can obtain great sunken side area and be used for the installation and clean the pad, so this scheme is a technical scheme who considers guarantee clean effect under the self-cleaning mechanism weight prerequisite.
Because the relative position of the arc-shaped plate and the pitching motor in the scheme is a fixed relation, the camera can rotate under the action of the pitching motor and cannot move along the radial direction of the arc-shaped plate, and in order to obtain enough contact force between the wiping pad and the lens to ensure the cleaning effect, an elastic material is preferably adopted as the wiping pad. The current pad of cleaning adopts the cloth usually, but the cloth application generally can not obtain sufficient contact force through self on this scheme, when adopting materials such as rubber to assist the required contact force of obtaining as the bed course between pad and the arc as cleaning, rubber density is great and the elastic coefficient is great, is unfavorable for the lightweight design of this cloud platform, leads to the every single move motor electric current too big easily when the arc vibrates, based on this, preferred, clean the pad for being curved block structure, clean the pad for the foam pad, clean the axis of pad and the axis collineation of every single move motor axle, clean the pad through hot melt adhesive paste in the sunken side. In this scheme, it is right the shape of cleaning the pad is injectd the rotation orbit that is used for matcing the camera lens, and the characteristics of foam pad porous, changeability make the camera lens can smoothly rotate and have better clean effect, adopt the hot melt adhesive to accomplish corresponding connection and be used for solving following problem: the foam is fragile under the extrusion of camera lens, for conveniently changing the foam provide one kind easily operate, need not add other connecting elements specially and lead to the connected mode that unmanned aerial vehicle machine carried weight increases. In a specific application, if the cambered surface on the inner side of the wiping pad is defined as an inner circular surface and the cambered surface on the outer side is defined as an outer circular surface, the camera needs to be installed such that the rotation track is located between the inner circular surface and the outer circular surface when the lens rotates to face the wiping pad under the action of the pitching motor. In order to facilitate the lens to sink into the foam pad, a chamfer is arranged at the position where the wiping pad is attached to the front end of the arc-shaped plate, so that the thickness of the front end of the wiping pad is smaller than that of the rear end of the wiping pad, the force required by the lens to sink into the wiping pad at the initial moment is reduced, and the purpose of prolonging the service life of the wiping pad is achieved.
In the prior art, the course arm is connected with the roll arm through the roll motor, so that the gravity center of the arc plate is close to the axis of the roll motor, the stress of the roll motor during working is optimized, and the precision of the roll deflection angle is improved.
When specifically implementing, as this steady image cloud platform batch production preparation to the technical scheme of accurate control arc position on the horizontal roll arm intermediate lamella sets up to: the arc-shaped plate is installed on the transverse rolling arm through welding connection or screw connection, and in the specific implementation, the screw connection mode is preferably adopted, so that the arc-shaped plate can be detached from the holder when a lens does not need to be cleaned in an aerial photography task, and the aim of reducing the mounting weight of the unmanned aerial vehicle is fulfilled; as a kind of originally reequip on current steady image cloud platform, obtain this scheme through the mode of installation arc on the intermediate lamella steady image cloud platform's technical scheme, set up to: the arc-shaped plate is fixed on the transverse rolling arm through a clamping seat and a connecting arm, the clamping seat is an anchor ear, one end of the connecting arm is connected with the clamping seat, and the other end of the connecting arm is connected with the arc-shaped plate.
As a light in weight, the arc material itself has better elasticity and is used for increasing the contact force of camera lens and wiping pad, the material weatherability is better, the convenient technical scheme who dismantles of wiping pad, sets up to: the arc-shaped plate is of a sheet structure made of polyethylene; the wiping pad and the arc-shaped plate are connected in a detachable mode.
For reducing to clean the dust on the pad itself and adhere to, do benefit to and promote clean effect and protection lens surface, set up to: the surface of one side that is used for wiping the camera lens on wiping the pad still bonds there is the protection film, the bonding strength of protection film and wiping the pad satisfies: the protective film can be separated or broken from the wiping pad when being scratched at the side surface of the lens barrel. In the scheme, the protective film can be paper or a plastic film and is used for preventing dust from being directly adhered to the wiping pad with a porous structure, and when the protective film is paper, the protective film can be broken under the rubbing action, and when the protective film is a plastic film, the protective film can be separated under the rubbing action. Can the concrete application for clean the pad and include evagination side, indent side, front end and rear end, evagination side and arc laminating, indent side orientation pitch motor axle, the front end is close to the front end of arc, and the rear side is close to the roll motor, the protection film only covers the indent side, like this, when the camera lens is rotatory, during the camera lens was embedded into by the front end of cleaning the pad and is cleaned the pad, utilizes the extrusion of lens barrel side to the protection film, breaks away from or the purpose of breaking more than can realizing.
Because the camera lens with wipe the pad when acting on mutually, inevitable can lead to the coating on the dust granule friction camera lens, thereby reach the purpose that reduces the influence to the lens surface for reducing the granule, set up as: the one end that is used for linking to each other with the roll arm on the arc is the rear end of arc, still installs the blast pipe on the front end of arc, be provided with the gas vent on the blast pipe, the orientation of gas vent satisfies: a purge gas may be provided to the camera lens. By adopting the scheme, when the lens rotates to the front end of the arc-shaped plate, part of dust particles on the lens can be swept by exhaust of the exhaust pipe, so that the number of dust particles introduced into the lens and between the lens and the wiping pad through the lens is reduced. Be different from adopting wasing water, gaseous density is less, when adopting the gas cylinder to carry purge gas, if purge gas only is used for sweeping of camera lens single, the gas cylinder weight that needs to carry is very little, simultaneously the power supply come from gaseous pressure that has can to need not dispose the pump, so this scheme when the protection camera lens, can realize unmanned aerial vehicle carry weight lightweight design. As a more complete scheme corresponding to the above scheme, the following scheme is set: the device is characterized by further comprising a gas cylinder for providing gas to the exhaust pipe, the gas cylinder is connected with a gas inlet of the exhaust pipe through a pipeline, and the heading arm is further provided with a hanging frame for carrying the gas cylinder.
This scheme is when specifically using, and the blast pipe discharge sweeps gaseous the emergence constantly of needs, and the technique of control circuit break-make among the prior art is more, but in this application, if for following control valve sets up solenoid valve, dedicated driving motor etc. also do not benefit to unmanned aerial vehicle machine and carry weight control, based on this design, set up to: the pipeline is also provided with a control valve for controlling the on-off of the pipeline, and the control valve further comprises a pitching motor arranged on the transverse rolling arm, the control valve comprises a valve rod and a linkage mechanism, and the pitching motor drives the valve rod to move through the linkage mechanism. In this scheme, because camera lens turned angle is controlled by every single move motor when needs are clean, so every single move motor's turned angle and camera lens have fixed relation for wiping the position of pad, blast pipe, on this basis, adopt every single move motor as the power unit of control valve switching, can make every single move motor control valve open when rotating under specific angle, not only need not set up special actuating mechanism for the control valve, adopt mechanical connection to reach required purpose simultaneously. As a person skilled in the art, alternatively, the control valve may be configured to perform on-off control adjustment by lifting a valve rod, such that a cam may be connected to a rotor of the pitch motor, and when the cam is rotated by the pitch motor until a protruding point thereon can act on the valve rod, the cam presses the valve rod to lift or lower along an axis of the valve rod to open the control valve, and when the protruding point on the cam is further rotated to be disengaged from the action of the valve rod, the valve rod is retracted to a state of closing the control valve by a return spring, and a specific form of the control valve may be a one-way valve in which a small ball provides a sealing surface; the gear that only has the teeth of a cogwheel on partial periphery of installation also can be on pitch motor's rotor, when the gear is rotatory to the teeth of a cogwheel contact on its teeth of a cogwheel and the valve rod, drives the valve rod rotation, opens for the control valve of forms such as ball valve, stop valve, discharges the gas in the gas cylinder through the blast pipe, is different from above cam form, and the gaseous single use in this scheme is fit for the gas cylinder: if the valve rod is provided with the reset mechanism, the valve rod rotates, the structure of the reset mechanism is relatively complex, and the lightweight design of the tripod head is not facilitated, so that the valve rod is preferably directly lifted, more preferably, a labor-saving lever can be arranged between the cam and the valve rod for reducing the valve opening load of the pitching motor, and the salient point on the cam drives the valve rod to move through the labor-saving lever. In addition, the above gear and cam schemes need to be installed as follows: when the lens of the camera rotates to the blowing position of the exhaust port on the exhaust pipe, the control valve is opened; the cam, the labor-saving lever and the gear are the components of the linkage mechanism.
The invention has the following beneficial effects:
this scheme provides an including steady image cloud platform of automatically cleaning mechanism, lies in with prior art's difference: through set up at the particular position and clean the pad, utilize the necessary every single move motor on the cloud platform to solve the camera lens and clean the contact problem of pad, like this, can needn't set up special motor for automatically cleaning mechanism again, when reaching the clean purpose of camera lens, can reduce unmanned aerial vehicle machine and carry weight, be favorable to prolonging unmanned aerial vehicle's time of endurance, increase the mileage of endurance, promote unmanned aerial vehicle's flight performance.

Corresponding with above prior art, this scheme provides a steady image cloud platform including automatically cleaning mechanism, and the difference with prior art lies in: through set up at the particular position and clean pad 3, utilize the necessary every single move motor on the cloud platform to solve the camera lens and clean the contact problem of pad 3, like this, can needn't set up special motor for automatically cleaning mechanism again, when reaching the clean purpose of camera lens, can reduce unmanned aerial vehicle machine and carry weight, be favorable to prolonging unmanned aerial vehicle's time of endurance, increase the mileage of endurance, promote unmanned aerial vehicle's flight performance.
More specifically, in the present solution, the pitching motor shaft 7 is the axis of the pitching motor rotor, and the axis of the arc-shaped plate 2 and the axis of the pitching motor shaft 7 are collinear, so that after the camera is rotatably mounted on the horizontal rolling arm 4 through the pitching motor shaft 7, the camera lens can contact the wiping pad 3 mounted on the concave side when rotating upwards by controlling the distance between the camera lens and the axis and the position of the camera lens on the axis, and the camera lens can wipe off dust attached to the camera lens through the relative movement between the camera lens and the wiping pad 3, so that the image stabilizing pan/tilt head has a self-cleaning function. Above in-process, carry out relevant clean action and can accomplish under every single move motor's action, for prior art, because every single move motor generally is the essential equipment on the cloud platform, need not set up special motor for wiping 3 work of pad promptly, so this scheme can effectively alleviate unmanned aerial vehicle's the weight of carrying on. By fixing the arc-shaped plate 2 on the cross rolling arm 4, the course action and the cross rolling action of the tripod head do not influence the action of the wiping pad 3 on the lens, and the lens is downward in normal aerial photography, so that the self-cleaning mechanism does not influence the normal shooting of the camera.

Because the relative position of the arc-shaped plate 2 and the pitching motor in the scheme is a fixed relation, the camera can rotate under the action of the pitching motor and can not move along the radial direction of the arc-shaped plate 2, and in order to obtain enough contact force between the wiping pad 3 and the lens to ensure the cleaning effect, an elastic material is preferably adopted as the wiping pad 3. Present clean pad 3 usually adopts the cloth, but the cloth application generally can not obtain sufficient contact force through self on this scheme, when adopting materials such as rubber to assist the required contact force of obtaining as the bed course between clean pad 3 and the arc 2, rubber density is great and the coefficient of elasticity is great, is unfavorable for the lightweight design of this cloud platform, leads to the every single move motor electric current too big easily when the arc 2 vibrates, based on this, preferentially, clean pad 3 for being curved massive structure, clean pad 3 for the foam pad, clean the axis of pad 3 and the axis collineation of every single move motor axle 7, clean pad 3 through hot melt adhesive paste in the sunken side. In this scheme, it is right the rotation orbit that is used for matching the camera lens is prescribed a limit to the shape of cleaning pad 3, and the characteristics that the foam pad is porous, yielding make the camera lens can smoothly rotate and have better clean effect, adopt the hot melt adhesive to accomplish corresponding connection and be used for solving following problem: the foam is fragile under the extrusion of camera lens, for conveniently changing the foam provide one kind easily operate, need not add other connecting elements specially and lead to the connected mode that unmanned aerial vehicle machine carried weight increases. In a specific application, if the cambered surface on the inner side of the wiping pad 3 is defined as an inner circular surface and the cambered surface on the outer side is defined as an outer circular surface, it is necessary to mount the camera such that the rotation track is located between the inner circular surface and the outer circular surface when the lens is rotated to face the wiping pad 3 under the action of the pitching motor. In order to make things convenient for the camera lens to sink into the foam pad, set up the chamfer in the position that wipes pad 3 and arc 2 front ends and paste for the thickness of wiping pad 3 front end is less than the thickness of rear end, in order to reduce the camera lens and sink into the required power of wiping pad 3 initial moment, reaches the purpose of extension wiping pad 3 life.
