Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1 to 4, the protection device of the side-push anti-drag noise reduction device of the embodiment includes a mounting frame 1, a protection cover 2, a sealing member 3, a liquid level switch 4 and a control valve 5.
The mounting frame 1 is welded on the outer shell 100 of the hull and is welded outside the cylinder 201 in the side-push resistance-reducing noise-reducing device, some driving and transmission parts related to the motion executing mechanism 202 needing protection are surrounded in the cylinder, and the motion executing mechanism 202 drives the rotating shaft through the swing type hydraulic cylinder to drive the gate 203 to open and close and rotate. The protective cover 2 is connected to the mounting frame 1, and covers all of some driving and transmission components related to the motion actuator 202 enclosed in the mounting frame 1 in the protective cover 2.
The mounting frame 1 can be firmly fixed by welding to support the protection cover 2. Set up a plurality of screw holes 11 on the installing frame 1, set up on the protection casing with the installing frame on screw hole position, aperture matched with through-hole or screw hole, make protection casing 2 realize threaded connection through bolt and installing frame 1, protection casing 2 forms the connected mode of convenient dismantlement with installing frame 1, conveniently gets into and overhauls or change the protection casing in the protection casing 2.
The mounting frame 1 is made of steel suitable for welding.
The protective cover 2 is made of a composite material with relatively light weight, so that the load of a hull outer plate and a side-thrust anti-drag noise-reduction device cylinder and the dead weight of a ship are reduced, the protective cover is easier to operate when being installed, detached or replaced in a limited space at the position, and meanwhile, the protective cover is more resistant to water corrosion. The composite material may be selected from glass fiber or carbon fiber, or other similar composite materials.
This scheme does not adopt protection casing lug weld on the hull planking, leave out the mode of installing frame, because if protection casing lug weld then the protection casing need adopt to be fit for welded steel, weight is heavier, and the barrel exterior space at the side thrust drag reduction and noise reduction device is very limited, the welding weight is heavy, the protection casing of bulky is operated and is wasted time, hard, it is difficult, and the later stage needs the cutting clearance when changing the protection casing, unsuitable convenient and fast dismantlement.
In order to ensure the connection tightness between the protective cover and the mounting frame, a sealing element 3 is arranged at the contact surface of the protective cover 2 connected with the mounting frame 1, the sealing element 3 is clamped and mounted between the protective cover and the mounting frame to seal the connection part of the protective cover and the mounting frame, so that a relatively closed space is formed in the protective cover, the water quantity permeating into the protective cover is reduced, and the corrosion of water to the driving and transmission parts related to the motion executing mechanism of the side-push resistance-reducing noise-reducing device in the protective cover is reduced.
However, as the time is accumulated, the sealing element and the connecting pipeline are aged, water and oil at the movable connection part are permeated, and permeated water or leaked hydraulic oil is inevitably accumulated in the protective cover. Consequently, still set up the liquid level switch 4 that detects the liquid level in the protection casing in this scheme. The liquid level switch 4 is contact-selectable, and is disposed inside the protective cover, such as a float switch, or non-contact, and may be disposed inside the protective cover, or disposed on the outer wall of the protective cover, such as a capacitive liquid level switch or an ultrasonic liquid level switch.
The bottom of the protective cover 2 is provided with a control valve 5 controlled by a liquid level switch 4.
When the water permeating into the protective cover 2 or the leaked hydraulic oil exceeds a set water level threshold value, the liquid level switch 4 controls the control valve 5 to be opened, and the water or the oil stored in the protective cover 2 is discharged and then closed.
The control valve 5 is a hydraulic valve, a pneumatic valve or an electric valve, and can also be a manual valve for periodically performing manual liquid drainage.
In other embodiments, a bleed valve may also be provided at the bottom of the shroud. When the water or the leaked hydraulic oil in the protective cover reaches a certain height and exceeds the opening pressure of the relief valve, the relief valve is opened, and the water or the oil stored in the protective cover is discharged and then closed.
The protective cover 2 is also provided with an oil way connector 6, so that the hydraulic cylinder in the protective cover can be connected with an external hydraulic pump station through a pipeline penetrating through the oil way connector, and hydraulic oil is provided for the hydraulic cylinder. Or the hydraulic cylinder and the hydraulic pump station are connected to the oil way interface through pipelines, and the oil way interface is communicated.
The protective cover can be provided with other interfaces for the protective connection of other control lines and other lines or pipelines.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
