Under, it is possible to it is present with crack, so as to cause to leak.The safety of dam can be caused to seriously affect when leaking serious.Therefore, greatly
Dam dam body needs to safeguard and check regularly, so as to find these crack leak sources and carry out respective handling.
Traditional leakage inspection method is to prepare ink on the coast, and diver's carrying one is connected soft with pressurized equipment on the bank
Pipe pulls the plug, and after reaching target point, diver opens the valve on hose, meanwhile, staff's startup pressurization on the bank is set
It is standby, by ink via in the water around hose press-in target point, the water body near target point is dyed, is split if the place has
Seam, the inside and outside of crack can will make the water body after dyeing flow into crack, so as to intuitively show the position in crack there are pressure difference.
Traditional leakage inspection method shortcoming following points：
1) need that shore facilities is connected with diver using hose, when working depth is deeper, hose is up to one
Very long length so that the volume of equipment is bigger than normal, weight is laid particular stress on；
2) hose follows diver's dive, and hose has situations such as winding, distortion in water, to the j ob impact of diver
It is larger, the life of diver can be even threatened when serious；
3) diver carries hose and moves under water, larger to the physical demands of diver；
4) bank base personnel is needed to be coordinated with diver, are limited by means of communication, work efficiency is low.

It puts, the delivery outlet connection efferent duct of the fluid reservoir, nozzle is installed on the efferent duct；There is traced fluid in the fluid reservoir.
Its further technical solution is：
The top of the fluid reservoir connects the second pipeline, the bottom connection efferent duct of the fluid reservoir.
The nozzle is check valve.
The traced fluid is ink.
Beneficial effects of the present invention are as follows：
The present invention is compact-sized, reasonable, easy to operate, passes through entire ink-jet tracer equipment, it may be convenient to realize and examine
Tracer means are provided when surveying the leakage of dam body underwater portion.
The present invention possesses the sealability in the case of deep water, can resist the extraneous hydraulic pressure of maximum 3MPa；
The present invention is autonomous device, aids in, can also may be used by diver's independent operation without bank base equipment and bank base personnel
It is easy to use to be equipped on the work of the underwater research vehicles such as manned underwater vehicle；
It is of the invention compared with traditional tracer equipment, small volume, lighter in weight can effectively improve diver or diving
Device carries out work efficiency during underwater tracer work；
It is of the invention compared with traditional tracer equipment, this patent single dive continuous working period is long, can save work
Cost.
The present invention can mountability it is superior, can be also equipped on manned underwater vehicle by diver's independent operation and be carried out work
Make.
The present invention is coordinated without bank base by diver or submersible independent operation, in addition, integration of the present invention is high, is avoided
The harmful effects such as the underwater distortion of hose, winding in conventional method.
The use of the present invention disclosure satisfy that the demands on examination of the underwater dam body of most dams from the limitation of the depth of water.

Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is illustrated.
As shown in Figure 1, the ink-jet tracer equipment for the underwater leakage detection of dam of the present embodiment, including source of the gas 1, source of the gas 1
Output terminal connects pressure reducer 5 by the first pipeline 3, and the first shut-off valve 2 and first pressure measuring device are equipped on the first pipeline 3
4, the output terminal of pressure reducer 5 connects fluid reservoir 9 by the second pipeline 8, and the second shut-off valve 6 and second is equipped on the second pipeline 8
Device for pressure measurement 7, the delivery outlet of fluid reservoir 9 connect efferent duct 10, nozzle 11 are equipped on efferent duct 10；Have in fluid reservoir 9
Traced fluid 12.
The top of fluid reservoir 9 connects the second pipeline 8, the bottom connection efferent duct 10 of fluid reservoir 9.
Nozzle 11 is check valve.
Traced fluid 12 is ink.
Source of the gas 1 of the present invention is the power source of device, and pressure-air is loaded in the inside；
The first shut-off valve 2 that the present invention tells a story is the switch of power source；
First pressure measuring device 4 of the present invention is used to refer to the residual compression of gas cylinder；
Pressure reducer 5 of the present invention is used for depressurizing the pressure-air in gas cylinder, and high pressure gas is prevented directly to be blown into liquid storage
Tank 9；
Switch of second shut-off valve 6 of the present invention as gas path on-off after decompression；
