Further, described cable slip antiwear device is connected with described cable expansion casing flexibility, and described cable tray is connected with described cable expansion casing stationarity.
Further, described cable slip antiwear device is made up of a pvc pipe and axostylus axostyle, and described pvc pipe is sleeved on described axostylus axostyle, and described axostylus axostyle and the U-shaped hook being welded on cable expansion casing both sides are that flexibility is connected.
Further, described case lid is fixedly connected with by stainless steel bolt nut with described cable expansion casing, and the joint of described case lid and described cable expansion casing is provided with 3MM nylon washer.
Further, described case lid is also provided with a pair handle.
Further, described flowing water plug is distributed in four angles of described cable expansion bottom half respectively.
Beneficial effect: structure of the present invention is simple, can make cable can be freely flexible under ship deformation condition, avoids and causes the construction of cable to be damaged because stretching, seawater can be prevented the erosion of cable simultaneously, ensure that the safe transmission of marine vessel power.

Embodiment
The waterproof cable expansion tank peculiar to vessel of one as depicted in figs. 1 and 2, comprise cable expansion casing 1, sealing coupling device 2, cable slip antiwear device 5 and cable tray 6, described cable expansion casing 1 both sides are run through flexibility by sealing coupling device 2 and are connected with cable tube 3, described sealing coupling device 2 comprises annular flange and the seal washer of strap bolt nut, described cable tube 3 is case of bending in described cable expansion casing 1 inside, cable slip antiwear device 5 and cable tray 6 is also provided with in described cable expansion casing 1, for supporting described cable tube 3, also be provided with several flowing water plugs 7 bottom described cable expansion casing 1, be fixed bottom described cable expansion casing 1 by casing installation adjusting device 8, described cable expansion casing 1 top is also provided with case lid 9.
As the further optimization of technique scheme, in order to ensure that this cable expansion tank has good water resistance and stretch-proof performance, between described sealing coupling device 2 and described cable tube 3, be also provided with electrical continuity device 4.Described electrical continuity device 4 comprises and connects copper sheet and ground strip.It is inner that described cable slip antiwear device 5 and cable tray 6 are symmetricly set on described cable expansion casing 1 respectively.Described cable slip antiwear device 5 is connected with described cable expansion casing 1 flexibility, and described cable tray 6 is connected with described cable expansion casing 1 stationarity.Described cable slip antiwear device 5 is made up of a pvc pipe and axostylus axostyle, and described pvc pipe is sleeved on described axostylus axostyle, and described axostylus axostyle is that flexibility is connected with the U-shaped hook being welded on cable expansion casing 1 both sides.Described case lid 9 is fixedly connected with by stainless steel bolt nut with described cable expansion casing 1, and described case lid 9 is provided with 3MM nylon washer with the joint of described cable expansion casing 1.Described case lid 9 is also provided with a pair handle.Described flowing water plug 7 is distributed in four angles bottom described cable expansion casing 1 respectively.
Above-mentioned waterproof cable expansion tank is carried out flexibility with cable tube be connected by the sealing coupling device casing that to be expanded by cable, and can ensure when ship deformation, the cable tube of insertion cable expansion tank can freely slide.
Above-mentioned cable antiwear device is connected with cable expansion casing flexibility, can ensure in the cable tube shifting process caused at ship deformation, and the cable laid wherein can be freely flexible.
A kind of waterproof cable expansion tank of the present invention, main needs are considered when ship deformation, cable tube and cable expansion tank cannot rigid connections, therefore sealing coupling device is devised, cable tube and cable expansion tank are carried out flexibility connection, can prevent seawater from entering in cable tube by sealing coupling device simultaneously.In order to provide the flexible surplus of cable, the design of cable antiwear device and cable tray is provided with difference in height, and when cable stretches because of ship deformation, the cable of this bend portions can provide flexible surplus.Cable antiwear device is that be enclosed within by a pvc pipe can on free rolling axostylus axostyle, axostylus axostyle and the U-shaped hook being welded on cable box both sides are that flexibility is connected, when cable is moved because of ship deformation, spindle rotation, PVC sleeve pipe also can freely rotate simultaneously, this makes it possible to ensure that cable can not cause damaging because of the friction of movement, cable tray also serves the effect of cable support.The design of electrical continuity device mainly considers that dependency rule requires cable tube entirety to need to keep electrical continuity and ground connection effectively.Should discharge timely in case stop loss bad cable when the design of flowing water plug is importantly considered in cable tube and may be occurred condensed water.The height that casing installation adjusting device is mainly used for when installing connect box and cable tube regulates.
The present invention is in actual boats and ships running, when occur because of expand with heat and contract with cold or ship deformation that Structure stress bends etc. when, cable tube and cable expansion tank carry out flexibility connection by sealing coupling device, the cable be laid in cable tube can freely slide, and seals coupling device simultaneously and can prevent seawater from entering in cable tube.The flexible surplus of cable is realized by this section of cable difference in height between cable antiwear device and cable tray, and when cable stretches because of ship deformation, the cable of this bend portions can provide flexible surplus.Cable antiwear device, when cable is moved because of ship deformation, can ensure that cable can not cause damaging because of the friction of movement.Ensure that the normal transport of electric power on the whole.
Structure of the present invention is simple, can make cable can be freely flexible under ship deformation condition, avoids and causes the construction of cable to be damaged because stretching, seawater can be prevented the erosion of cable simultaneously, ensure that the safe transmission of marine vessel power.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
