Technical Field
The invention relates to the technical field of underwater operation tools of manned submersible vehicles, in particular to an ink-jet tracing device for dam underwater leakage detection.
Background
After the reservoir dam is used for a period of time, the underwater part of the dam body may crack under the action of water flow scouring and self weight, so as to cause leakage. When the leakage is serious, the safety of the dam can be seriously influenced. Consequently, dam bodies require frequent maintenance and inspection to find these crack leakage points and to deal with them accordingly.
The traditional leak detection method is that ink is prepared on the shore, a diver carries a hose connected with a pressure device on the shore to submerge into water, after the diver reaches a target point, the diver opens a valve on the hose, meanwhile, a worker on the shore starts the pressure device to press the ink into the water around the target point through the hose to dye the water body near the target point, if a crack exists in the position, pressure difference exists between the inside and the outside of the crack, and the dyed water body flows into the crack, so that the position of the crack is visually displayed.
The traditional leak detection method has the following defects:
1) the shore equipment and a diver need to be connected by using a hose, and when the working depth is deep, the hose reaches a very long length, so that the equipment is large in size and heavy in weight;
2) the hose submerges along with a diver, and the hose is wound, twisted and the like in water, so that the operation of the diver is greatly influenced, and even the life of the diver can be threatened when the hose is serious;
3) the diver carries the hose to move underwater, which causes great physical consumption to the diver;
4) the shore-based personnel and the diver are required to be matched, the working efficiency is low due to the limitation of communication means.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, the inkjet tracing apparatus for underwater leakage detection of a dam of the present embodiment includes an air source 1, an output end of the air source 1 is connected to a pressure reducer 5 through a first pipeline 3, the first pipeline 3 is provided with a first stop valve 2 and a first pressure measuring device 4, an output end of the pressure reducer 5 is connected to a liquid storage tank 9 through a second pipeline 8, the second pipeline 8 is provided with a second stop valve 6 and a second pressure measuring device 7, an output port of the liquid storage tank 9 is connected to an output pipe 10, and the output pipe 10 is provided with a spray head 11; the liquid storage tank 9 is filled with a tracer liquid 12.
The top of the liquid storage tank 9 is connected with a second pipeline 8, and the bottom of the liquid storage tank 9 is connected with an output pipe 10.
The spray head 11 is a one-way valve.
The tracer liquid 12 is ink.
The air source 1 is a power source of the device, and high-pressure air is filled in the air source;
the first stop valve 2 of the invention is a switch of a power source;
the first pressure measuring device 4 is used for indicating the residual pressure of the gas cylinder;
the pressure reducer 5 is used for reducing the pressure of high-pressure air in the air bottle and preventing the high-pressure air from being directly blown into the liquid storage tank 9;
the second stop valve 6 is used as a switch for switching on and off the gas path after pressure reduction;
the first pipeline 3 and the second pipeline 8 are gas circuit connecting elements of the whole set of equipment;
the liquid storage tank 9 is a pressure-resistant container, can resist the pressure of the external water depth, and can be used for filling tracer liquid 12;
the spray head 11 is a one-way valve which is used as an outlet of the tracer liquid 12 and can prevent external water from entering the device;
the tracer liquid 12 is ink, is generally made of colored pigment and is used for indicating the existence of cracks;
the second pressure measuring device 7 of the present invention is used for measuring the pressure of the decompressed gas and also for guiding the setting of the decompression pressure of the decompressor 5.
When the device works, a diver or a submersible carries the whole device to enter water, and after the device reaches a target operation area, the first stop valve 2 is opened, and the indicated value of the first pressure measuring device 4 is observed, wherein the indicated value is the rated working pressure of a gas cylinder. Then the second stop valve 6 is opened, the gas flows through the pressure reducer 5, the second stop valve 6 and the second pressure measuring device 7, at the moment, a diver or a submersible can finely adjust the outlet pressure of the pressure reducer 5 according to the depth of the target operation area and the reading of the second pressure measuring device 7, so that the outlet pressure is slightly larger than the water depth pressure of the target area, and the trace liquid 12 and high-pressure gas are prevented from being wasted due to overlarge pressure of the decompressed gas. Then, high-pressure gas flows to the top of the liquid storage tank 9 through the second pipeline 8, under the action of pressure, the tracer liquid 12 is extruded out of the bottom of the liquid storage tank 9, the extruded tracer liquid 12 flows out of the equipment through the spray head 11, and at the moment, a diver or a submersible observes the diffusion condition of the extruded tracer liquid 12 in water by enabling the spray head 11 to be close to a suspected crack area, so that the crack can be judged.
The above description is intended to be illustrative and not restrictive, and the scope of the invention is defined by the appended claims, which may be modified in any manner within the scope of the invention.
