In formula: S
k---hydraulic giant fulling water columm length (m);
L---hydraulic giant is exported to water receiving vessel inlet projector distance (m) on the ground;
A---hydraulic giant axis and horizontal angle (elevation angle).
The principle of work of native system jetting system is as follows: before test, first the blue laser alignment clamp 1-2-1 on opening installation interface 1-2, penetrates the upper-lower height at the level angle of the orientation adjustment mounting interface 1-2 of water receiving vessel inlet circular hole and vertical angle or adjustment mounting interface 1-2 according to laser.When needing the level angle adjusting mounting interface 1-2, adjusting handle 1-3-6 is horizontally rotated by rotating, make the first straight-tooth worm gear 1-3-4 drive the first fan-shaped spur gear 1-3-2 to realize horizontally rotating within the scope of 0-90 °, the horizontal rotating disc 1-3-7 being simultaneously fixed on gear shaft upper end also rotates thereupon; Be connected to mounting interface 1-2 in vertical rotating mechanism 1-4 along with the first fan-shaped spur gear 1-3-2 horizontally rotates simultaneously together, when mounting interface 1-2 rotates to required level angle, rotation horizontally rotates locking handle 1-3-5 and is locked on upper shell 1-1 by horizontal rotational shaft dish 1-3-7, thus fixed installation interface 1-2 level angle.When needing the vertical angle adjusting mounting interface 1-2, second straight-tooth worm gear 1-4-4 is along with the rotation of vertical rotary adjusting handle 1-4-6, the second fan-shaped spur gear 1-4-2 is driven to realize vertical rotary within the scope of 0-90 °, mounting interface 1-2 is along with the second fan-shaped spur gear 1-4-2 vertical rotary together simultaneously, when mounting interface 1-2 rotates to required vertical angle, rotate vertical rotary locking handle 1-4-5, underframe 1-4-8 is locked by the second coupling shaft 1-4-10, thus fixed installation interface 1-2 vertical angle.When needing the upper-lower height adjusting mounting interface 1-2, helical teeth worm gear 1-5-4 in leading screw and worm gear seal shell 1-5-1 is along with the rotation of lift adjustment handle 1-5-8, leading screw 1-5-2 is driven to move up and down, realizing up-down adjustment scope is ± 250mm, leading screw 1-5-2 drives mounting interface 1-2 to move up and down by underframe 1-4-8, when mounting interface 1-2 moves to required height, rotate lifting locking handle 1-5-7, by shell 1-1 in lower casing 1-6 locking, thus secure the height of mounting interface 1-2.
The structure criteria of right and wrong shell of the upper shell 1-1 in jetting system 1, its effect horizontal rotary mechanism 1-3, vertical rotating mechanism 1-4, mounting interface 1-2 and elevating mechanism 1-5 is connected to one by gear shaft and coupling shaft.
Native system adopts jetting system that the jet of hydraulic giant can be made to aim at the import of water receiving container accurately.Because the setting height(from bottom) of water receiving container is higher, its below is connected with volumometer measuring tank by the pipeline that catchments, when jet due to hydraulic giant injects water receiving container, its impulsive force is very large, therefore being fixed on firm water receiving container carrier in its below by water receiving container support post, this bracket is not only equipped with moveable wheel but also have the push rod can fixed with ground.
According to the above description, scheme of the present utility model can be realized in conjunction with art technology.
