Problems solved by technology

The disadvantage is that multiple bolts are often required, and it is difficult to ensure that all bolts are disconnected at the same time
[0004] The structure of the underwater load dumping device is simple, but after the load dumping is completed, the cavity at the original connection cannot be sealed, resulting in a situation where the sealing performance of the equipment itself is greatly affected after the load dumping is completed

Embodiment 1

[0025] see Figure 1-5 , the present invention provides a technical solution: a load dump structure for underwater equipment, including a device body 1, the bottom surface of the equipment body 1 is fixedly connected to the load dump part 2, and a cylindrical sliding cavity 21 is set at the center of the bottom surface of the load dump part 2 , the cylindrical sliding cavity 21 is slidingly connected with the cylindrical heavy object 3, the bottom surface of the cylindrical heavy object 3 is fixedly connected to the heavy object arc-shaped bottom 31, and the top surface of the heavy object arc-shaped bottom 31 contacts the bottom surface of the ejection part 2, and the heavy object arc The top surface of the shaped bottom 31 is evenly fixed to four load dumping columns 32, and the bottom surface of the load dumping part 2 corresponds to the positions of the four dumping columns 32, and four installation column slots 22 are respectively opened;

[0026] The four mounting column...

Embodiment 2

[0028] see Figure 4 , the bottom surface and side wall of the sealed push plate 42 are affixed to the second electromagnet 49, the top surface of the ejection column 32 is fixedly embedded with the first electromagnet 33, and the inner wall of the bottom surface of the ejection sleeve 4 is affixed to the third electromagnet 410. The column 32 and the sealing push plate 42 are fixed to each other by the electromagnet. When dumping, the first electromagnet 33 on the top surface of the dumping column 32 is invalidated. After dumping the load dumping column 32, the sealing push plate 42 falls on the dumping On the bottom surface of the loading chamber 41, the third electromagnet 410 is started at this time, and the sealing push plate 42 is fixed on the bottom surface of the loading chamber 41 for sealing.

[0029] see Figure 4The top surface of the throwing cavity 41 is fixedly connected with a plurality of abutment columns 46, the bottom of the abutment column 46 contacts the ...

Embodiment 3

[0035] When the present invention is in a normal state, the first electromagnet 33 on the top surface of the dumping column 32 is in an open state, the third electromagnet 410 on the inner side wall of the bottom surface of the dumping chamber 41 is in a closed state, and the cylindrical weight block 3 is inserted into the column. In the sliding cavity 21, and the four dumping posts 32 are respectively plugged in the four dumping chambers 41, and the first electromagnet 33 on the top surface of the dumping post 32 and the second electromagnet 49 on the bottom surface of the sealing push plate 42 Absorb and fix, and when carrying out load dumping, power supply 24 is energized, and corroded wire 44 is corroded and fractured, and first spring 45 and second spring 47 apply force to sealing push plate 42 at this moment, can push down and carry out load dumping, in While dumping, the first electromagnet 33 on the top surface of the dumping column 32 is closed, and the third electroma...

Abstract

The load rejection structure comprises an equipment body, a load rejection part is fixedly connected to the bottom face of the equipment body, a cylindrical sliding cavity is formed in the center of the bottom face of the load rejection part, a cylindrical weight block is slidably connected into the cylindrical sliding cavity, and a weight arc-shaped bottom is fixedly connected to the bottom face of the cylindrical weight block. The top face of the arc-shaped bottom of the heavy object makes contact with the bottom face of the load rejection part, four load rejection columns are evenly and fixedly connected to the top face of the arc-shaped bottom of the heavy object, and four installation column grooves are formed in the positions, corresponding to the four load rejection columns, of the bottom face of the load rejection part respectively. The four load rejection columns and the four load rejection sleeves corresponding to the four load rejection columns are uniformly arranged, so that load rejection stress is uniform, the jamming condition is avoided, after load rejection is completed, a sealing push plate is mutually fixed with a third electromagnet on the inner side wall of the bottom surface of a load rejection cavity through a second electromagnet on the side wall, the load rejection cavity is sealed, and the load rejection efficiency is improved. And meanwhile, the hydraulic cylinder is started to push the sealing circular plate down to the bottom surface of the cylindrical sliding cavity, so that the cylindrical sliding cavity is sealed, and the sealing after the load rejection work is completed is ensured.

Description

technical field [0001] The invention relates to the technical field of underwater dumping equipment, in particular to a dumping structure for underwater equipment. Background technique [0002] With the development of my country's ocean exploration technology, ocean exploration instruments, especially deep-sea instruments, are more and more widely used in scientific research and investigation. When marine exploration instruments work underwater, due to the complex operating environment, in case of emergency situations such as failure and power failure, in order to ensure that the instrument can be recovered safely, it is necessary to set up a dumping device to dump the heavy objects carried by the instrument so that The instrument uses its own buoyancy to rise to the sea surface. And it can also increase the sinking and floating speed of the marine instrument by dumping the weight, saving the time for underwater operations. At present, the dumping system mainly includes el...
