A telescopic rod for underwater vehicle salvage and rescue

Abstract

This invention relates to a telescopic boom for underwater vehicle salvage and rescue. The boom body has a front mechanical claw with a power source fixed at its front end and a rear mechanical claw with a power source fixed at its middle. A buoyancy rope turntable is fixed on the boom body. A buoyancy rope is folded in half at the middle and wound around the buoyancy rope turntable, with a pair of rope ends connected to a front buoyancy ball and a rear buoyancy ball, respectively. When the front mechanical claw closes, it hooks the front buoyancy ball to prevent it from floating; when the rear mechanical claw closes, it hooks the rear buoyancy ball to prevent it from floating. The rear mechanical claw is connected to one end of a steel wire, and the other end of the steel wire is connected to a ratchet catch. The ratchet catch hooks onto a ratchet to prevent it from reversing. The ratchet and the buoyancy rope turntable are coaxially fixed and can rotate synchronously. During the extension of the boom body, the buoyancy rope, under tension, can drive the buoyancy rope turntable and ratchet to rotate forward. When the rear mechanical claw opens under the power source, it drags the steel wire to disengage the ratchet catch from the ratchet.

DETAILED DESCRIPTION

[0038] The present invention is described below in conjunction with the accompanying drawings and specific embodiments.

[0039] Embodiment 1:

[0041] In this embodiment, see Figure 1-2 And 5-6, also include: a straight connecting piece; the straight connecting piece is provided with a blaster 3 at the front end, and the rear end can be axially detachably connected to the front end of the telescopic rod body, and the front mechanical claw 2 and the front buoyancy ball 1 are fixed on it; it is suitable for when the vehicle is in an upright posture underwater, so that the blaster blasts the window horizontally, and the telescopic rod body passes through the vehicle body horizontally.

[0042] In this embodiment, see Figure 8 The buoyancy rope rotating disc 8 is provided with a buoyancy rope disc clamping opening 8.1 for hooking the buoyancy rope at the part folded in half from the middle.

[0043] In this embodiment, the front buoyancy ball 1 and the rear buoyancy ball 6 are each connected to a rope ring, and the front mechanical claw 2 is closed by clamping the rope ring to hook the front buoyancy ball 1; the rear mechanical claw 7 is closed by clamping the rope ring to hook the front buoyancy ball 1; in addition, Figure 3 As shown, the top of the front buoyancy ball 1 is provided with a self-luminous light source 1.1. The rear buoyancy ball 6 is also provided with the self-luminous light source, which is not shown in the drawings.

[0044] In this embodiment, the blaster 3 is provided with a rotating motor for enhancing the blasting effect, which is not shown in the drawings.

[0045] Preferably, the rotation and telescopic power source is an underwater motor 11 arranged at the end of the telescopic rod body.

[0046] In this embodiment, see Figure 4The underwater motor 11 is fixedly connected to the first telescopic rod 9 through a motor hinge flange 10 .

[0047] In this embodiment, the front end of each telescopic rod is provided with a limit switch for telescopic limit. Figure 4 shown.

[0048] The working method of the telescopic rod for underwater vehicle salvage and rescue, the buoyancy rope winding direction:

[0049] Make sure that when the ratchet rotates in the positive direction, the buoyancy rope tends to unfold;

[0050] When the telescopic rod body does not rotate, the ratchet clamp 27 clamps the ratchet 8.2, and the buoyancy rope drum does not rotate;

[0051] When the telescopic rod body rotates and extends, the front mechanical claw 2 and the rear mechanical claw 7 respectively pull the steel wire 26, and the ratchet clamp 27 is lifted; at the same time, the two ends of the buoyancy rope are pulled to drive the buoyancy rope turntable 8 to rotate so that the buoyancy rope is separated from the buoyancy rope disc clamp 8.1, completing the release of the buoyancy rope;

[0052] The front buoyancy ball 1, the rear buoyancy ball 6 and the buoyancy rope float upward under the action of their own buoyancy.

[0053] Working principle of buoyancy rope drum:

[0054] 1. Fold the buoyancy rope in half, hang it on the buckle in the middle of the buoyancy rope drum, and wind the rope in the direction of the ratchet. The two ends of the rope are placed on the buoyancy balls of the front and rear ends of the telescopic rod body.

[0055] 2. When the telescopic rod is not working, the ratchet is stuck and the buoyancy rope drum does not rotate; when the telescopic rod is working, the clamp on the servo pulls the wire, the ratchet is lifted, and the buoyancy rope drum rotates with the movement of the cable driven by the telescopic rod and the buoyancy of the cable itself. When it rotates to the end, the cable will fall off from the buckle in the middle of the buoyancy rope drum, completing the release of the cable.

[0056] Before the claw is released, the rope guide drum relies on the telescopic rod to drive the movement of the rope to achieve counterclockwise rotation. The ratchet structure has a certain pre-tightening force, and the ratchet card can prevent the rope from loosening or falling off as the ratchet reverses; when the front end float is sent out of the other side of the bus window by the telescopic rod, the two claws release the float at the same time, and the claws on the rear end rope guide drum release the ratchet card at the same time. The rope guide drum is in a follow-up state, relying on the floating action of the rope on the float to drive the rope guide drum to rotate, thereby releasing the rope by inertia.

[0057] This embodiment is suitable for when the vehicle is in an upright position underwater, after the blaster blasts the vehicle window horizontally, the telescopic rod body horizontally passes through the vehicle body. The accompanying drawings do not show the vehicle falling into the water.

[0058] It should also be noted that the telescopic rod for underwater vehicle salvage and rescue can be used in conjunction with an underwater rescue robot, and the underwater rescue robot itself is already a prior art and will not be described in detail herein.

[0059] Embodiment 2:

[0060] The difference between this embodiment and the first embodiment is that the straight connecting piece at the front end of the telescopic rod body is replaced with a single-side hook connecting piece, such as Figure 10-12 shown.

[0061] The front end of the single-sided hook connector is provided with a blaster 3, and the rear end can be axially detachably connected to the front end of the telescopic rod body, and the front mechanical claw 2 and the front end buoyancy ball 1 are fixed thereon; it is suitable for when the vehicle is standing sideways underwater, and the blaster is used to blast the window downward, and the hook part of the single-sided hook connector hooks the cross bar inside the vehicle.

[0062] like Fig.12 As shown, the blaster at the front end of the single-sided hook connector is provided with a rotating motor 31 for enhancing the blasting effect.

[0063] Continue to see Fig.12 The hook portion of the single-sided hook connector has a telescopic anchor arm 29 for adjusting the length.

[0064] The rest of the structure of this embodiment is the same as that of the first embodiment.

[0065] This embodiment is suitable for when the vehicle is standing sideways underwater. After the blaster blasts the window horizontally, the telescopic rod body passes through the vehicle body downward. Then the single-side hook connector at the front end rotates a certain angle to hook the column of the sunken vehicle, and then releases the buoyancy ball. Fig.14 As shown, the accompanying drawings do not show the vehicle that has fallen into the water.

[0066] Working principle of the telescopic rod on the side of the sunken vehicle falling into the water:

[0067] The bus tilted due to the water falling into it, penetrating 3 to 4 windows on one side.

[0068] 1. The telescopic method and glass breaking method at the rear end of the telescopic rod are consistent with the upright working principle. The main difference lies in the structure of the front mechanical claw 2. The telescopic anchor arm 1 of the mechanical claw 2 is a single arm, and the corresponding applicable length can be adjusted according to the column size of the water truck.

[0069] 2. After the glass is broken, the motor of the second mechanical claw at the front end of the telescopic rod rotates 90 degrees (or the front telescopic rod rotates 90 degrees), and the anchor hook is used to fix the bus column. The claw is loosened to release the buoyancy ball, and the buoyancy ball rises with the buoyancy rope.

[0070] The above two items are optional embodiments of the present invention. Ordinary technicians in this field can also make various changes or improvements on this basis. Without departing from the overall concept of the present invention, these changes or improvements should fall within the scope of protection required by the present invention.
