Underwater hydraulic oil cylinder anti-oil-spilling and waterproof structure and method

Abstract

The invention provides an oil-spill-proof and waterproof structure and method for an underwater hydraulic oil cylinder, the oil-spill-proof and waterproof structure comprises the hydraulic oil cylinder, the hydraulic oil cylinder is fixedly mounted on a water retaining door body, the top end of the hydraulic oil cylinder is provided with an oil-spill-proof and waterproof end cover for preventing oil spill and water leakage, and the oil-spill-proof and waterproof end cover is connected with an oil-water monitoring and alarming device. By means of the structure, hydraulic oil environment pollution and inflow water emulsification caused by damage of the V-shaped sealing piece of the underwater hydraulic oil cylinder can be prevented, the hydraulic oil leakage and inflow conditions of the underwater hydraulic oil cylinder can be monitored and checked rapidly and conveniently, and meanwhile the leakage position of the underwater hydraulic oil cylinder can be judged in an auxiliary mode.

Description

technical field

[0001] The invention relates to an oil spill prevention and waterproof structure and method for an underwater hydraulic oil cylinder, and belongs to the field of underwater hydraulic oil cylinders. Background technique

[0002] For hydraulic cylinders that work underwater, due to the frequent extension or retraction of the piston rod of the hydraulic cylinder, the V-shaped seals at the end cover of the hydraulic cylinder will be worn and other problems, causing the hydraulic oil in the hydraulic cylinder to flow out to the surrounding waters, causing Environmental pollution and other problems will also cause the water in the surrounding waters to enter the hydraulic cylinder, causing problems such as emulsification of hydraulic oil in the hydraulic cylinder, which seriously affects the equipment reliability of the hydraulic cylinder. It is very inconvenient to monitor these problems such as oil spill pollution and hydraulic oil inflow emulsification. The insp...

Examples

Embodiment 1

[0034] see Figure 1-5 , an underwater hydraulic oil cylinder anti-spill and waterproof structure, which includes a hydraulic oil cylinder 1, the hydraulic oil cylinder 1 is fixedly installed on the water blocking door body 4, and the top of the hydraulic oil cylinder 1 is installed with an anti-spill and water-proof end for preventing oil spills and water leakage. The cover 2 and the oil-spill-proof and waterproof end cover 2 are connected with the oil-water monitoring and alarm device 3 . Through the provided anti-spill and waterproof end cover 2, the forward sealing end cover 201 and the reverse sealing end cover 205 of the oil cylinder form a bidirectional sealing combined structure, so as to prevent the hydraulic oil of the hydraulic cylinder from flowing into the surrounding water and prevent the surrounding water from flowing into the hydraulic cylinder the goal of.

Embodiment 2

[0043] The method for preventing oil spilling and waterproofing of a hydraulic oil cylinder with an oil-spill prevention and waterproof structure for an underwater hydraulic cylinder includes the following steps:

[0044] Step 1: The hydraulic cylinder 1 working underwater is in a normal state. When the piston and the piston rod 104 perform the retracting action, the cylinder stroke detection sensor 202 transmits the action position signal of the hydraulic cylinder 1 to the control station through the cable. The upper chamber of the hydraulic cylinder 1 The pressure is in a high pressure state, the pressure in the inner cavity of the cylinder forward sealing end cover 201 is always zero. Leakage; the inner cavity pressure of the forward sealing end cover 201 of the cylinder is always zero, which is less than the water pressure in the surrounding environment of the hydraulic cylinder 1, and the V-shaped seal in the reverse sealing end cover 205 is also in normal working conditio...
