Description
Technical field
The present invention relates to unmanned plane aviation plant protection technical field, specifically, be related to it is a kind of it is automatic it is anti-swing stability maintenance nobody
Machine liquid case.
Background technology
Pesticide refers to harmful organism (pest organism mouse etc.) and coordinate plant growth that agriculture forest and husbandry production is endangered for preventing
Chemicals.Pesticide can be destroyed plant diseases and insect pests, increased production, protecting receipts, can also be prevented and be controlled infectious disease etc., to ensure increases in grain production,
Increasing peasant income and agricultural product effective supply play an irreplaceable role, and are the indispensable means of production of agricultural modernization and to rescue
Calamity goods and materials.With the development of social economy and the quickening of modernization, the whole world is still in and day to the demand of pesticide and fertilizer
The situation all increased.And the excessive application of pesticide and fertilizer is a big obstruction of world today's development precision agriculture.Liquid foliar fertilizer
And increasingly attract attention and favor, meanwhile, liquid is carried out by easily operated and highly effective and safe unmanned plane and sprays operation
It is the important development direction of modern agriculture.
With the development of Chinese agriculture production technology, the utilization rate of agricultural unmanned plane also steps up.Agricultural plant protection nobody
Machine has spraying efficiency height, sprays the advantages such as uniform, good, the at low cost and job safety of effect, is increasingly subject to the green grass or young crops of peasant
It looks at.Plant protection unmanned plane spraying efficiency is 2.67~6.67hm2·h- 1, be equivalent to 100 times of artificial spraying efficiency, with spraying swath 60m,
Gait of march 6kmh- 1Large-scale plant protection instrument it is suitable.Liquid case as one of the ost important components in agricultural plant protection unmanned plane,
The reasonability of design directly affects the security and spraying effect of unmanned plane during flying.Existing unmanned plane liquid case is mostly using tradition
Design, under the states such as start-stop, acceleration, deceleration and steering, the liquid in liquid case can become unmanned plane with the state of unmanned plane
Change and vibrate, UAV system entirety center of gravity is caused to shift, directly affect stability or even the production of unmanned plane during flying
Raw safety problem.Therefore, design a kind of unmanned plane liquid case that can mitigate liquid oscilaltion to promoted the safety of agricultural unmanned plane with
Stability has important meaning.
The content of the invention
The purpose of the present invention is to provide a kind of automatic anti-unmanned plane liquid case for swinging stability maintenance, and the liquid that can automatically control liquid case begins
The state being full of is maintained eventually, efficiently solves the problems, such as the unbalance that unmanned plane is generated because of liquid oscilaltion in case.
To achieve these goals, the automatic anti-unmanned plane liquid case for swinging stability maintenance provided by the invention includes babinet and arranged on case

Body flows to outer intracavitary from interior case.
More specific scheme is set for partition plate parallel to head cover；Liquid outlet is arranged on the one side of partition plate, and liquid outlet is connected with
One passes through the conduit of the bottom of box.It is moved up or down with the stretching motion partition plate of electric cylinder push rod.The babinet of the program
It can be cylindrical or cuboid.
Preferred scheme is mounted on the bottom center of head cover for liquid level sensor.Liquid level sensor can monitor closed in real time
Water level information in cavity.With spraying for liquid, the liquid level in closed cavity declines, and easily generates vibration.Liquid level sensor
Set a suitable watermark threshold, when liquid level descends below watermark threshold, liquid level sensor transmit a signal to electric cylinder into
Row work, push rods at different levels stretch out band dynamic dividing plate and move upwards successively, liquid water level lifting, and revert to the state being full of, and vibrate
Mitigate.After water level is more than watermark threshold, electric cylinder is stopped, reciprocal with this.
Another more specific scheme includes the side wall parallel to babinet and two pieces be oppositely arranged, electric cylinder bag for partition plate
Two be symmetrically mounted in babinet opposing sidewalls are included, and two electric cylinders are by same control switch control.It is symmetrical
Two partition plates conformably move in or out simultaneously with the stretching motion of electric cylinder push rod, it is ensured that the center of gravity of babinet
It remains unchanged.The babinet of the program is preferably cuboid.
More specific scheme is arranged on the bottom center of babinet for liquid outlet.To two partition plates with maximum moving range.
More specific scheme is that liquid level sensor includes two be respectively arranged on two partition plates.Two liquid level sensors
Water level information in closed cavity can be monitored in real time.With spraying for liquid, the liquid level in closed cavity declines, and easily generates and shakes
It swings.A suitable watermark threshold is set to liquid level sensor, when liquid level descends below watermark threshold, liquid level sensor transmission
Signal works to electric cylinder, and push rods at different levels stretch out successively drives the inwardly movement simultaneously of two partition plates, liquid water level lifting, and extensive
It is multiple be full of state, vibration mitigates.After water level is more than watermark threshold, electric cylinder is stopped, reciprocal with this.
Preferred scheme is removably mounted on the top of babinet for head cover.Inside clean box body.
Another preferred scheme is connected for liquid outlet by woven hose with nozzle.It can be efficiently by the liquid in liquid case
Extraction is sprayed.
Compared with prior art, beneficial effects of the present invention are：
The unmanned plane liquid case for being automatically prevented from spraying liquid oscilaltion of the present invention utilizes water in the real-time monitoring case of liquid level sensor
Position information simultaneously transmits a signal to actuator, is worked by actuator and babinet internal partition is driven to move, and automatically controls the liquid of liquid case
Always the state being full of is maintained, efficiently solves the problems, such as the unbalance that unmanned plane is generated because of liquid oscilaltion.Meanwhile
The liquid case has the characteristics of intensity is high, and quality is small, and capacity is big, assemble the unmanned plane of the liquid case have the advantages that stablize it is safe.
