Abstract
An airtight sealing device for the dredger elbow sucking port, relates to a sealing device for a dredger elbow sucking port, solving the sealing problem induced between an elbow and a hull sucking port. The utility model including an air-filled tube, an inflation latex sealing ring, a U look latex sealing ring, and a connecting bolt, is characterized in that the sealing device is provided with a fixing ring with air-filled pore and step look cross section; air-filled pore of outer ring of the fixing ring is connected with the air-filled tube; inner ring of the fixing ring is beset with a inside lining ring which is provided with a convex ring outside the annular wall; the annular ring formed between the outside annular wall of the inside lining ring and the step of the fixing ring is provided with the inflation latex sealing ring, whose charging mouth is connected with the air-filled tube in the inner ring of the fixing ring; one side of the convex ring of the inside lining ring is closed to the side that install the inner ring step of the fixing ring, and is provided with the U look latex sealing ring connected by the bolt. The utility model is designed to seal the joint between a dredger elbow and a hull sucking port.
Description
Technical field:
The utility model relates to the sealing device of dredging vessel bend pipe suction inlet.
Background technology
The rake pipe that trailing suction hopper dredger needs will be positioned on the boats and ships main deck when ship dredging construction hangs into carrying out operation under water, the rake pipe is made up of bend pipe, intervalve, drag head three parts usually, wherein bend pipe is glided along the hull chute by the bend pipe slide block and hangs onto the suction inlet position, needs to engage between the bend pipe that therefore has a rake pipe and the hull suction inlet and guarantees effective sealing problem.Be provided with the underwater dredge pump device on the deepwater dredging working ship rake pipe, sealing load is a malleation between bend pipe slide block and the hull suction inlet like this, and pressure is about+2bar; And tradition adopts the trailing suction hopper dredger of dredge pump in the cabin, and sealing load is a negative pressure between bend pipe slide block and the hull suction inlet, pressure pact-0.6bar; Both have essential distinction in this place's sealing.Adopt the trailing suction hopper dredger of dredge pump in the cabin, sealing device mainly is made up of rubber ring, pressing plate, set bolt between bend pipe slide block and the hull suction inlet; After slide block puts in place, the rubber ring of the sealing device sealing that is squeezed between bend pipe slide block and the hull suction inlet, owing to be negative pressure in the pipe, seal request is not high, this form can meet the demands.The deepwater dredging working ship is owing to be provided with the submersible pump device on the rake arm, the discharge pressure of submersible pump is+2bar, in the pipe is malleation, this requires to seal between bend pipe slide block and the hull suction inlet reliable, at bend pipe and hull suction inlet joint as can not positiver sealing, the fluid (silt particle) that certainly will take place in the piping produces leakage at joint, causes problems such as efficiency of construction decline and generation environment pollution.Therefore require positiver sealing between bend pipe slide block and the hull suction inlet, could guarantee the normal of stowage system.
The utility model content
It is the trailing suction hopper dredger bend pipe of barotropic fluid (silt particle) and the sealing problem between the hull suction inlet that the utility model need solve between bend pipe and the hull suction inlet.
The utility model comprises the employing gas tube, the pneumatic rubber seal circle, U-shaped rubber seal and connecting bolt, it is characterized in that having in the sealing device cross section one-tenth step and have the erection loop of inflating the duct, air-filled pore with the erection loop outer shroud connects gas tube, the interior ring of erection loop is inlayed the inner bushing ring that there is a convex circle in a ring wall outside, in the annular groove that constitutes between the step of the inner bushing ring ring wall outside and erection loop the pneumatic rubber seal circle is installed, the inflation duct of ring in the charging connector connection ring of pneumatic rubber seal circle, convex circle one side of inner bushing ring is near a side of ring step in the erection loop, and with bolt the U-shaped rubber seal is installed in a side of the convex circle of inner bushing ring.
The utility model can be installed in bend pipe slide block mouth with nut, after hull suction inlet position is arrived in the slide block slippage, compressed air is inflated the pneumatic rubber seal circle through gas tube, erection loop, charging connector, make pneumatic rubber seal circle inside be subjected to compression swelling, between bend pipe slide block and hull suction inlet plane, produce closely and mediate, guarantee positiver sealing between bend pipe slide block and hull suction inlet.This device is through the construction application of time more than a year, prove this device effectively, reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the utility model is installed in the schematic diagram on the bend pipe slide block.
The specific embodiment
Implement best way of the present utility model below in conjunction with description of drawings:
The utility model (see figure 1) comprises employing gas tube 1, pneumatic rubber seal circle 3, U-shaped rubber seal 5 and connecting bolt, a cross section one-tenth step is arranged in the sealing device and have the erection loop 2 of inflating the duct, air-filled pore with erection loop 2 outer shrouds connects gas tube 1, the interior ring of erection loop 2 is inlayed the inner bushing ring 4 that there is a convex circle in a ring wall outside, in the annular groove that constitutes between the step of the inner bushing ring 4 ring walls outside and erection loop 2 pneumatic rubber seal circle 3 is installed, the charging connector of pneumatic rubber seal circle 3 is connected with the inflation duct of ring in the erection loop 2, convex circle one side of inner bushing ring 4 is near ring step one sides in the erection loop 2, and with bolt U-shaped rubber seal 5 is installed in a side of the convex circle of inner bushing ring 4.
The utility model is installed in bend pipe slide block 6 (see figure 2) mouths at erection loop outer shroud adapted bolt, U-shaped rubber seal 5 that is provided with in the sealing device and bend pipe mouth are along sealing, after hull suction inlet position is arrived in the slide block slippage, compressed air is inflated pneumatic rubber seal circle 3 through gas tube, erection loop, charging connector, 7 mouthfuls of edge sealings of pneumatic rubber seal circle 3 and hull suction inlet; Equipped sensor and control device, the blowing pressure Failure Alarm device on the loading line replenish air automatically in case the generation air leaks, and can guarantee all the time that the blowing pressure is constant.When ship dredging construction finishes the rake arm to be risen when winching on the boats and ships main deck, air in pneumatic rubber seal circle 3 inflatable chambers discharges through loading line, make the rubber retraction, between bend pipe slide block and hull suction inlet, produce to break away from gap (being about 1mm), the rubber that guarantees sealing device bend pipe break away from the hull suction inlet rise to do not drawn in the motion process of main deck bad.
