Abstract
The utility model discloses a sealing device at the lifting place of an underwater telescopic and full circle swinging electric propeller for the ship. The sealing device comprises a bushing bearing support arranged at the outer side of a bushing, wherein, the inner wall of the bushing bearing support is provided with a gap block, the bushing bearing support is provided with a sealing filler seat, and sealing filler is filled in the space formed between the inner wall of the sealing filler seat and the bushing. The sealing device prevents seawater from leaking into the cabin from the cabin plate lifting place.
Description
Technical field
The utility model relates to marine equipment, relates in particular to the sealing arrangement at the propelling unit of telescopic electric under water cover piping support peculiar to vessel place.
Background technology
Adopt the boats and ships of electric plating propulsion driving at present; its electric plating propulsion has the dual-use function that power and rudder are provided concurrently; the general suspension rod supporting electric plating propulsion that adopts; captiveed joint with electric plating propulsion in the lower end of suspension rod, play the effect of supporting electric plating propulsion, for the protection suspension rod is not subjected to marine denudation; skin at suspension rod is set with sleeve pipe; the lower end of sleeve pipe extends to the junction of suspension rod and electric plating propulsion, and between suspension rod and sleeve pipe sealing arrangement is installed, and prevents that seawater is from this intrusion.Because the electric plating propulsion that disposes on the common ship only need possess propulsion functions and revolute function, thereby the upper end of sleeve pipe is fixed in the sleeve pipe supporting base, the sleeve pipe supporting base is a split type structure, its inwall is the face of cylinder, outside face adopts spiral to connect or the method for welding is fixed on the cabin plate of hull, the upper end of the suspension rod in the sleeve pipe is rotatably supported on the hull, makes that suspension rod can be around self rotational, thereby realizes the revolute function of electric plating propulsion by rotating suspension rod.Different with general boats and ships is, be symmetrically installed with a plurality of electric plating propulsions around the semi-submersible offshore auxiliary vessel, its radical function is used in ocean balance hull and short range running fix, thereby the degree of depth under water in electric plating propulsion when work is greater than the degree of depth under water of hull bottom, this just makes the semi-submersible offshore auxiliary vessel dragged in the navigation by other Power Vessels, because the degree of depth under water of electric plating propulsion touches submerged reef and other obstacle easily greater than hull bottom, cause the accident, thereby require the function that electric plating propulsion not only has provides power and full circle swinging, also to have scalable function under water, make electric plating propulsion when auxiliary vessel is worked, extend, when navigating by water, shrinks by auxiliary vessel, this just requires suspension rod and sleeve pipe to rise together or to descend along boom axis, make the electric plating propulsion of captiveing joint rise synchronously or descend with suspension rod, thereby sleeve pipe can not be fixed in the sleeve pipe supporting base, and to slidably be bearing in the sleeve pipe supporting base, in addition, be in partially surfaced condition during ocean engineering vehicle work, the sleeve pipe supporting base is immersed in the seawater, this just requires at sleeve pipe supporting base position, i.e. lifting place installing sealing arrangement, in the prevention seawater bleeds the cabin from lifting, do not find the data and the product of this respect at present as yet.
The utility model content
Technical problem to be solved in the utility model is that a kind of flexible under water, full circle swinging electric plating propulsion lifting place sealing arrangement peculiar to vessel will be provided, and the sealing device can stop in seawater bleeds cabin from cabin plate lifting.
The scheme that the utility model technical solution problem adopts is: a kind of flexible under water, full circle swinging electric plating propulsion lifting place sealing arrangement peculiar to vessel, comprise the sleeve pipe supporting base of being located at outside of sleeve, the inwall of described sleeve pipe supporting base is equipped with bearing shell, on this sleeve pipe supporting base the gland packing seat is installed, is filled with gland packing in the formed space between the inwall of sealing filler seat and the described sleeve pipe.
Owing to adopt such scheme, the sleeve pipe lifting of can in the sleeve pipe supporting base, sliding, and in lifting process, owing to be filled with gland packing between gland packing seat and the sleeve pipe, seawater can not enter in the cabin, satisfied the telescopic requirement of ocean engineering vehicle electric plating propulsion under water, again owing in the sleeve pipe supporting base bearing shell is housed, sleeve pipe there are location and supporting role, so no matter sleeve pipe is in lifting process, still in the process of transmitting electric plating propulsion thrust, sleeve pipe can not damage gland packing, has guaranteed the normal operation of gland packing.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
Fig. 2 is the enlarged drawing of local A in the structure shown in Figure 1.
The specific embodiment
Fig. 1, among Fig. 2, be welded with sleeve pipe supporting base 7 on the cabin plate 11 of hull, the inwall of sleeve pipe supporting base 7 is equipped with the bearing shell 6 that the Polymer graphite material is made, installation method is that the outside from sleeve pipe supporting base 7 is fixed on bearing shell 6 with screw on the inwall of sleeve pipe supporting base 7 (screw does not draw the figure), the top of sleeve pipe supporting base 7 also is equipped with gland packing seat 1, be filled with the graphite grazing filler 4 of 6 circle rope forms in the gap between the inwall of gland packing seat 1 and the sleeve pipe 3, the top of gland packing seat 1 is equipped with gland packing gland 2, be used for pinch-off seal filler 4, have circular groove 8 on the inwall of the gland packing seat 1 of close bearing shell 6, have hole 12 on the periphery of circular groove 8, and and pressurized air gas circuit connection.Be embedded with opening air bag 9 in the circular groove 8, branch compression ring 10 is housed in the opening air bag 9, block material ring 5 is equipped with in the bottom of sleeve pipe supporting base 7.
During work, bearing shell 6 carrying sleeves 3 of sleeve pipe supporting base 7, because the material of bearing shell 6 is the Polymer graphite material, its decay resistance and every physical and chemical performances such as high-temperature behavior, self-lubricating property and crocking resistance all are better than the plain bearing that white alloy or other material are made bearing shell, have prolonged the service life of plain bearing greatly.Gland packing 4 in the gland packing seat 1 is pressed on the outer wall of sleeve pipe 3, prevention continues to enter in the cabin from the seawater that bearing shell 6 infiltrates, the effect of opening air bag 9 is when gland packing 4 lost efficacy, make its expansion by pressurized air, and be pressed on the sleeve pipe 3, play the effect of emergency leakage blocking, block material ring 5 is used to remove the outer field ocean of sleeve pipe attachment.
