The burying device for the single seabed mud-entering detector is lowered below a water surface 34 through a crane 35, the underwater posture and the underwater entering depth of the device are judged through two bathymeters 18 and an underwater inclination angle sensor 2, after the device reaches the seabed, the device automatically sinks through self weight, and a nozzle seat 26 is inserted into a mud surface 37.
The working principle of the invention is as follows: the invention relates to a burying device of a seabed mud entering detector, which is characterized in that in use, a detector 31 is firstly installed in a detector installation cavity 29 on a ship, and a spray head preventing sheet 33 is installed to fix the detector 31. The crane 35 lowers the whole device to the seabed, and the underwater posture and the underwater depth of the device are judged through the two bathymeters 18 and the underwater tilt sensor 2. After the device reaches the seabed, the device automatically sinks by self weight, and the spray head device is inserted into soil.
And observing the integral posture of the device on the water surface, closing the top-push high-pressure pipe and the exhaust pipe valve, and opening the sinking high-pressure pipe valve. High-pressure gas enters the spray head device after passing through the annular spaces of the outer side and the inner side ventilation sleeves, and is sprayed out through the spray nozzle through the fluid channel of the spray head device. The three nozzles simultaneously spray high-pressure air downwards to impact and loosen the lower soil body, and slowly sink through the self weight of the device.
In the sinking process, monitoring parameters of the water surface, the posture of the device, the mud penetration depth and the high-pressure gas pressure need to be paid attention to all the time. When the inclination angle of the device exceeds 10 degrees, high-pressure gas is required to be sprayed in a pause mode, the sling is lifted up to enable the posture of the device to be smaller than 10 degrees, and then the high-pressure gas is sprayed. When the above processes are repeated, the inclination angle is still larger than 10 degrees, and the mud entering depth is not increased any more. At the moment, all the hose valves are closed, the exhaust pipe valve is opened, the sinking pipe is connected with the submersible pump and is injected into the water body, the gas in the annular space of the inner sleeve and the outer sleeve is discharged under the self-weight action of the water body, and the annular space is full of the water body through the exhaust pipe to the water surface by observing that no bubbles emerge from the water surface, so that the exhaust pipe valve and the sinking pipe valve are closed, and the sinking pipe is switched to be high-pressure gas. And opening a valve of the sinking pipe to downwards push the water body to be sprayed out through the nozzle by injecting high-pressure gas. The device continues to sink through the high-pressure hydraulic cutting impact action of the nozzle.
And when the sludge enters the preset depth, closing the valves of the sinking pipe and the exhaust pipe. And opening the pushing pipe valve. The pushing pipe gas pushes the upper pushing plate 23, the plunger 24 and the lower pushing plate 28 to move downwards through the inner vent sleeve 21, the detector 31 is pushed out of the detector accommodating cavity 29, the nozzle stopping sheet 33 is pushed away, and the detector 31 is separated from mud of the device. The device is lifted and recovered, and the detector 31 is left in the soil.
The device adopts remote control underwater construction, is simple and easy, can ensure that the detector is not damaged in the process of sinking into mud, can finish mud entering under water without artificial diving, can be repeatedly used, and can recover and continue to construct the next detector after one detector is constructed.
