8, manipulation unmanned boat returns correct track, so that the autonomous navigation of unmanned boat is realized, until completing all planning air routes.
Similar with sail mode, the sampling mode of unmanned boat of the present invention is divided into three kinds, and working method is as follows:
Equipment 13 is controlled when static sample point is preset in unmanned boat arrival according to the location information judgement of GPS chip feedback
Automatically the circuit of brushless motor propeller 10 can be disconnected or according to remote control command, unmanned boat stops, and winch 14 discharges towing cable 12,
Towed body 11 enters underwater heavy.According to the water pressure data that pressure sensor 24 returns in real time, towed body 11 is judged by control equipment 13
The locating depth of water.When towed body 11 is deposited to the predetermined depth of water, winch 14 stops working, and suction pump 15 is started to work, and water sample is led to
It crosses the extraction of drinking-water pipe 20 to come up, and is discharged into water sample cabin 16.After reaching water withdrawal, suction pump 15 stops working, and winch 14 is tightened
Towing cable 12, towed body 11 rise reset from water, and unmanned boat starting starts to navigate by water again.
The location information judgement fed back according to GPS chip, when reaching default continuous sampling point, control equipment 13 can be certainly
Power dynamic or that brushless motor propeller 10 is reduced according to remote control command, reduces the unmanned boat speed of a ship or plane and saves to 1-2, then winch 14 is released
Towing cable 12 is put, towed body 11 enters underwater heavy.According to the water pressure data that pressure sensor 24 returns in real time, judged by control equipment 13
The depth of water locating for towed body 11.When towed body 11 is deposited to the predetermined depth of water, winch 14 stops working.Towed body 11 follows nothing at this time
People's ship travels forward, have part water then can flow through monitoring pipeline 25, and by pipeline sensor test and analyze.Analysis gained
Terrestrial base station is transmitted to by communication module after data back to the control backup of equipment 13.When the detection and analysis for completing the default depth of water
After work, winch 14 tightens towing cable 12, and towed body 11 rises reset from water, and unmanned boat, which improves the speed of a ship or plane, to be continued to navigate by water.
In order to realize that operation is analyzed in the continuous sampling on room and time, needs before unmanned boat sets out or executing
During task, sampling analysis operation process is planned, and respective nodes data are transmitted at control equipment 13, the section
Point data is mainly made of preset time nodal value and predetermined depth nodal value two parts.According to the position letter of GPS chip feedback
Breath judgement, when unmanned boat is navigated by water to predetermined continuous sampling analysis site, control equipment 14 can automatically or according to remote control command into
Row sampling analysis operation.The power of brushless motor propeller 10 can be reduced first by controlling equipment 13, make the near 1-2 of the unmanned boat speed of a ship or plane
Section.Then control equipment 13 is issued to winch 14 and is instructed, and winch 14 starts to discharge towing cable 12, towed body downwards with constant speed
11 enter water.Towed body 11 can also travel forward while decline under the dragging of unmanned boat, and be located at 11 surrounding of towed body
The chemistry and related physical biosensor analysis that water understands some therefore flows through monitoring pipeline 25 and wherein installed analyze data
It will be transmitted to after control equipment 13 backs up and terrestrial base station is transmitted to by communication module.When winch 14 discharges towing cable, control
Equipment 13 starts timing, and is compared in real time with the preset time nodal value of storage.The pressure being mounted on towed body 11 passes
Sensor 24 can judge the depth of water locating for towed body 11 whereby, when towed body 11 in real time to control equipment 13 feedback pressure data
When locating depth reaches predetermined depth nodal value, the beginning of winch 14 is rotated backward with identical constant speed, tightens towing cable 12, band
Dynamic towed body 11 rises up to next predetermined depth nodal value, so in cycles.Reach pre- between controlling 13 timing of equipment
If when timing node value, control equipment 13 can issue instruction tightening towing cable 12 to winch 14.After resetting to towed body 11, control is set
The power of standby 13 adjustment brushless motor propeller 10, the raising of the unmanned boat speed of a ship or plane continue to navigate by water.
As described above, unmanned boat needs into the water to carry out towed body 11 continuous sampling in practical work process, and
This will inevitably generate biggish towrope resistance, and then adversely affect to the rapidity and endurance of unmanned boat.
To solve this problem, inventor has found following two solution: looking for solution from the mechanism for generating towrope resistance first
Certainly scheme.In view of the speed of a ship or plane positive correlation of towrope resistance and unmanned boat, so when unmanned boat discharges and recycles towed body
When 11, need to reduce the speed of a ship or plane of unmanned boat, this speed of a ship or plane is preferred with -2 section of 1 section.
On the other hand, inventor's discovery can use wave energy to reduce towrope resistance, this is also towed body 11 of the present invention
The important embodiment of middle torpedo main body 22 and the design of 23 structure of powered by wave energy hydrofoil.Due to the operation waters of unmanned boat be related to from
The farther away region of bank, therefore unmanned boat will certainly encounter relatively large wave.In wave, unmanned boat can generate vertical fortune
It is dynamic, and the movement is passed into towed body 11 by towing cable 12 and is allowed to also make catenary motion.During making catenary motion,
Upper the installed powered by wave energy hydrofoil 23 that can be rotated within the scope of positive and negative 20 degree of towed body 11 will receive the effect of water and
It generates and swings, and effect of the meeting of powered by wave energy hydrofoil 23 with certain angle of attack by front incoming flow after swinging, and then generate
Lift and resistance.At this point, powered by wave energy hydrofoil 23 will receive self gravity, the lift and drag effect of water, and the conjunction of three
Power shows as forward thrust, can further offset towrope resistance suffered by towed body 11 by this part thrust.Wave
Hydrofoil 23 can be driven to have acted in effect as the underwater propeller of towed body 11, and be located at the unmanned boat of the water surface then by brushless motor
Propeller 10 is responsible for propulsion, thus forms propulsion mode multi-level up and down, reduces unmanned boat and towed body to the greatest extent
System internal force between 11 reduces interfering with each other between the two, and be utilized on the whole reproducible wave energy with too
Sun can energize together for unmanned boat system, realize significantly promotion of the unmanned boat in endurance.
To further illustrate that powered by wave energy hydrofoil 23 has acted in effect as the work of the underwater propeller of towed body 11
Principle is made described further below in conjunction with Fig. 9 and Figure 10: setting wave driving hydrofoil as section is NACA0018, and the span is
The standard wing of 1.4m.It will receive the influence of wave when unmanned boat navigates by water on the water and generate heaving, when unmanned boat is met with
When wave wave crest, unmanned boat is moved upwards, and drives towed body to move upwards by towing cable.During moving upwards, wave
Wave driving hydrofoil will receive the downward resistance of water effect, and rotates around the axis to be formed as example is shown in Fig. 9 under the action of resistance
Form.
When unmanned boat meets with trough, unmanned boat is moved downward, at this time towing cable diastole, and towed body is then in self gravity
Under the action of move downward.During moving downward, wave driving hydrofoil will receive water effect upward resistance, and
It rotates around the axis to form legend form shown in Fig. 10 under drag effect.
No matter in Fig. 9 or in Figure 10, using force resolution principle, wave driving hydrofoil can all generate one in level
The size of power on direction, power is:
Propulsive force F=| lift L × sin α-resistance D × cos α |
In formula, α is the angle for closing speed and horizontal direction.In actual moving process, because NACA0018 is the resistance that rises higher
Than aerofoil profile, so lift L is greater than resistance D's always, and according to measured data, the heaving speed V2 of unmanned boat, which is less than, to be come
Flow velocity degree V1's, therefore lift L × sin α is greater than resistance D × cos α always, so wave driving hydrofoil can mention always
For forward propulsive force.
During towing, if towed body does not install wave driving hydrofoil, in order to make towed body follow unmanned boat
Horizontal motion is done, unmanned boat needs through towing cable to be to provide drag, for overcoming towed body and towing cable suffered in water
The resistance arrived.And if being mounted with that wave drives hydrofoil, under above-mentioned principle, wave driving hydrofoil can provide for towed body
Propulsive force horizontally forward, this propulsive force is with drag direction on the contrary, therefore towed body can be offset to a certain extent and dragged
The resistance in cable course in water.According to experiment and numerical simulation as a result, per a piece of wave driving hydrofoil under design conditions, i.e.,
When speed of incoming flow is 2 sections or so, maximum can provide the propulsive force more than 60N, then six hydrofoil maximums can provide and be more than
The propulsive force of 360N, this propulsive force even maximum thrust (about 217N) of separate unit brushless motor propeller, therefore it is mounted with wave
Wave driving hydrofoil can reduce resistance suffered in unmanned boat motion sample analytic process well, be conducive to extend unmanned boat
Voyage and preferably complete sample water intaking task.
