Optionally, the buoyancy body 17 is made of a non-metallic material and has a positive buoyancy. The invention is made to be zero buoyancy by the balance weight of the balance weight body 2. The installation will not influence the posture of the cable in the water at the cut cable 18, and has high adaptability.
Optionally, the dissolving block 20 is a salt block or a sugar block, and can be dissolved when meeting water. The dissolution speed of the dissolution block 20 determines the delay time of the cable cutting of the present invention, and the delay time can be adaptively adjusted by adjusting the volume of the dissolution block 20.
The invention is sealed by the first sealing ring 3, the second sealing ring 7, the third sealing ring 14, the fourth sealing ring 24, the annular sealing gasket 15, the first sealing gasket 9 and the second sealing gasket 25, so that the actuating mechanisms (the first spring 5, the second spring 12 and the third spring 22) are in a water-free state before the action of the invention, the resistance applied by water before the action is ensured, and the balance of the mechanism force is broken.
When the invention is not immersed in water, the spacing between the base body 1 and the counterweight body 2 is realized through the steel ball 6, and the felting needle 16 and the annular dye box 11 keep a certain distance through the elasticity of the second spring 12. The invention is used by fixing at the cut cable 18 of the underwater equipment. After entering the water, the water passes through the water inlet hole 19 to make the dissolving block 20 contact with the water to start dissolving. When the dissolving block 20 is dissolved, the third spring 22 drives the cutting knife 21 to move downwards, the cutting knife head 21A penetrates through the through groove at the bottom of the central cavity of the buoyancy body 17, cuts off the cut cable 18 and presses the upper part of the top cover 13. The top cover 13 is linked with the control rod 4 to move downwards to compress the second spring 12, so that the puncture needle 16 punctures the annular dye box 11; meanwhile, the annular groove in the middle of the control rod 4 is aligned with the two clamping slot holes of the counterweight body 2, and the steel ball 6 falls into the annular groove. The counterweight body 2 is separated from the substrate 1 under the action of the first spring 5, and the invention starts to float upwards under the buoyancy action of the buoyancy body 17 until water flows out. After the base body 1 and the counterweight body 2 are separated, water enters the upper cavity of the base body 1 from the lower cavity of the base body 1 along a gap between the base body 1 and the control rod 4, so that the coloring agent is dissolved in the water, and the water area near the water outlet point of the invention is colored and displayed, thereby being convenient for fishing and recycling.
According to the invention, after the cut cable 18 is cut off, the counterweight body 2 is separated, thrown and floated, and meanwhile, water reaches the upper cavity through the lower cavity of the substrate 1 and a gap between the control rod 4 and the substrate 1, so that the upper cavity is communicated with outside water. After the puncture needle 16 punctures the annular dye box 11, the striking dye inside the annular dye box 12 is dissolved in water, so as to achieve the purpose of indicating the floating position of the invention.
The invention provides a device for cutting off a cable or powering off an underwater cabled device in a delayed manner. The mechanical cable cutting device is applied to underwater time delay and can automatically float up and recover, dye and indicate the position after cutting the cable. The device is suitable for underwater cable cutting lifesaving equipment, underwater cable cutting floating recovery equipment and underwater equipment needing delayed power failure. It can also be used for underwater lifesaving equipment which can cut off the cable in a delayed way. When the cable is cut off, the counter weight 2 is thrown off and floats to the water surface, and the coloring agent is released to make the surrounding water area show striking color, so that the effective position display is convenient for salvaging and recycling.
It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
