Problems solved by technology

[0005] When the reversing bucket scoop control device adopts switch type control, the movement stroke of the piston rod of the reversing bucket scoop driving oil cylinder is only related to the time when the control handle is operated, so the reversing bucket scoop cannot be positioned at the target position through the position of the control handle, which cannot be realized Accuracy of reverse bucket scoop control

Embodiment 1

[0030] An embodiment of the present invention provides a bucket scoop control device for a water jet propulsion device, see Figure 1 to Figure 4 , the device includes: an installation box 1, a rotating shaft 15 installed in the installation box for connecting with the control handle, a cam plate 16, a limit switch installation plate 12 for fixing on the bucket spoon drive shaft 14, a The ascending limit switch 131 and descending limit switch 132 of control bucket scoop motion, cam plate 16 are fixed on the rotating shaft 15, ascending limit switch 131 and descending limit switch 132 are installed on the limit switch mounting plate 12.

[0031] Wherein, the gap between the ascending limit switch 131 and the descending limit switch 132 matches the width of the raised portion 161 of the cam plate 16, and the cam plate 16, the ascending limit switch 131 and the descending limit switch 132 cooperate with each other, when When the raised portion 161 of the cam plate 16 is aligned w...

Embodiment 2

[0049] The embodiment of the present invention provides a bucket scoop control method of a water jet propulsion device, which can be realized by using the device provided in Embodiment 1, see Figure 5 , the method includes:

[0050] Step 501: Obtain a control instruction issued by the control handle, the control instruction is used to indicate the target position of the bucket;

[0051] In this embodiment, the mechanical arm obtains the control handle through the mechanical flexible shaft to issue a control command, and drives the rotating shaft and the cam plate to move according to the control command, so that the cam plate moves to the target position. target location. The target position is a specified position where the control handle moves and stops. The action of the control handle can be to make the bucket rise or fall, and finally the control handle, mechanical arm, rotating shaft and cam plate are all at the target position.

[0052] Step 502: Detect the actual po...

Abstract

The invention discloses a bucket control device and method of a water spray pushing device, and belongs to the technical field of control over the water spray pushing device. The device comprises an installation box, a rotating shaft, a cam plate, a limiting switch installation plate, a rising limiting switch and a falling limiting switch, wherein the rotating shaft is arranged in the installation box and used for being connected with a control handle, the limiting switch installation plate is used for being fixed to a bucket driving shaft, the rising limiting switch and the falling limiting switch are used for controlling the movement of a bucket, the cam plate is fixed to the rotating shaft, the gap between the rising limiting switch and the falling limiting switch is matched with the width of the protruding portion of cam plate, when the protruding portion of the cam plate is aligned with the rising limiting switch, the rising limiting switch is triggered, and when the protruding portion of the cam plate is aligned with the falling limiting switch, the falling limiting switch is triggered. The cam plate triggers the limiting switches and keeps the bucket in a target position according to the mechanical position difference value between the cam plate and the limiting switch installation plate, the bucket is positioned in the target position according to the position difference, and accuracy of control over the bucket is ensured.

Description

technical field [0001] The invention relates to the technical field of control of a water jet propulsion device, in particular to a bucket and scoop device and method for a water jet propulsion device. Background technique [0002] The water jet propulsion device is a ship propulsion method that uses the reaction force of the water pump to spray water behind the ship to make the ship move forward. The water flow ejected by the water-jet propulsion device changes the spray direction through the reverse bucket scoop mechanically connected with the water-jet propulsion device, thereby changing the sailing direction of the hull. Because of the high propulsion efficiency, water-jet propulsion devices have been widely used in various high-speed ships such as ferries, yachts, and speedboats. Such ships using water-jet propulsion devices have high speeds, requiring fast and stable front and rear operations of ships. sex, precision. Therefore, the control of the reversing bucket sc...
