Change the upside plate face of resistance change-over panel and the angle of directional velocity, adjusts the degree of conversion of resistance, and then accurately control increase
Pressure size.
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings:
Fig. 1 is the overall structure diagram of the embodiment of the present invention.
Specific embodiment
Referring to Fig.1, the present invention is that a kind of drag head ground pressure increases device, including the rake pipe 4 hinged with dredger and is set
The drag head main body 1 in rake 4 end of pipe is set, is hinged with resistance change-over panel 2 in drag head main body 1, resistance change-over panel 2 is relative to drag head
The top surface inclination of main body 1, the direction of advance of the epipleural of resistance change-over panel 2 facing towards drag head main body 1, drag head main body 1 and resistance
Telescopic driving device 3 is additionally provided between change-over panel 2, the both ends of driving device 3 are separately connected drag head main body 1 and resistance conversion
Plate 2.
This drag head ground pressure increases device, and due to the inclination of resistance change-over panel 2 and epipleural is facing towards in drag head main body 1
Direction of advance, therefore when drag head main body 1 is advanced under water, the upside plate face of water impact resistance change-over panel 2 can be by water flow pair
A part of resistance of drag head main body 1 is converted to downward pressure, to increase drag head main body 1 to the pressure of sea bottom surface, in addition
It can also be turned by the flexible of driving device 3 to change the angle of the top surface of resistance change-over panel 2 and drag head main body 1 to change resistance
The upside plate face of plate 2 and the angle of directional velocity are changed, the degree of conversion of resistance is adjusted, and then accurately controls the big of increased pressure
It is small.
Water resistance is converted into vertical direction ground pressure value and relatively transverse speed, resistance change-over panel by resistance change-over panel 2
Angle, resistance conversion plate suqare are related, specifically, resistance change-over panel effect pressure P=K*V*S*tg (a) over the ground, wherein K is stream
Body resistance conversion coefficient, V are the relative moving speed of drag head main body 1, and S is the area of resistance change-over panel 2, and a is resistance change-over panel 2
With the angle of the top surface of drag head main body 1.
It is further used as the improvement of technical solution of the present invention, and pressure sensor, pressure sensor are additionally provided in driving device 3
