Abstract
The invention relates to a cable leakage stopper of a water flow generator, which mainly solves the technical problem that the cable of the water flow generator has the defect of air tightness. The cable leakage stopper comprises a shell, a plug and an elastic sealing sleeve, wherein the inner side of the shell is provided with a storage cavity, a through hole which is communicated with the storage cavity is formed in the bottom of the shell, the elastic sealing sleeve is embedded into the storage cavity, the plug is fixedly connected with the shell, the plug is matched with the elastic sealing sleeve in a pushing manner, a penetration hole is formed in the plug, a sealing hole is formed in the elastic sealing sleeve, the penetration hole, the sealing hole and the through hole are successively arranged, and the sealing hole is in a conical shape and is gradually narrowed towards the direction of the through hole along the penetration hole. Since the cable leakage stopper of the water flow generator adopts the sealing structure of the elastic sealing sleeve, when the cable is connected into the water flow generator, the sealing performance of the cable can be improved.
Description
Technical field
The present invention relates to the sealing device of a kind of hydroelectric generator, refer in particular to the cable leak stoppage device of a kind of water flow generator.
Background technology
Generating power by water current unit by converting the mechanical energy of the hydraulic turbine to through the hydraulic turbine, and hydraulic turbine pushing generator again generates electricity, and converts mechanical energy into electric energy, it is achieved the function of generating. Water flow generator needs cable transmission electric power, and cable is when being connected with water flow generator, it is necessary to carry out sealing, it is prevented that current enter generator affects its work.
Summary of the invention
In order to overcome shortcoming and the weak point of background technology, the present invention provides the cable leak stoppage device of a kind of water flow generator, and the cable solving water flow generator exists the technical problem of sealing defect.
The technical scheme is that the cable leak stoppage device of a kind of water flow generator, including shell, plug blocks up and elastic seal cartridge, the inner side of described shell is provided with containing cavity, the bottom of described shell is provided with the through hole communicated with containing cavity, described elastic seal cartridge embeds in described containing cavity, stifled the fixing with shell of described plug is connected, and described plug is stifled with the press-fit of elastic seal cartridge top, stifled being provided with of described plug penetrates hole, described elastic packing is arranged with sealing hole, described penetrate hole, seal hole and through hole sets gradually, described sealing hole is cone-shaped, along penetrating hole towards through hole direction in being gradually reduced.
Described hole, sealing hole and the through hole of penetrating sequentially coaxially is arranged.
Being provided with thread groove outside the containing cavity of described shell, described plug blocks up and described thread groove threaded engagement.
Described elastic seal cartridge is made up of elastomeric material.
Described elastic seal cartridge is cone-shaped.
Described plug blocks up and is provided with outwardly extension.
The method have the advantages thatOwing to the cable leak stoppage device of this water flow generator adopts the sealing structure of elastic seal cartridge so that cable is when being connected into water flow generator, it is possible to realize increasing its sealing property.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure, shell 1, plug stifled 2, elastic seal cartridge 3, containing cavity 4, through hole 5, penetrate hole 6, seal hole 7, thread groove 8, extension 9.
Detailed description of the invention
Below for accompanying drawing, embodiments of the invention are described further:
As shown in the figure, a kind of cable leak stoppage device of water flow generator, including shell 1, plug stifled 2 and elastic seal cartridge 3, the inner side of described shell is provided with containing cavity 4, the bottom of described shell 1 is provided with the through hole 5 communicated with containing cavity 4, described elastic seal cartridge 3 embeds in described containing cavity 4, described plug stifled 2 is fixing with shell 1 to be connected, and described plug stifled 2 pushes up press-fit with elastic seal cartridge 3, described plug stifled 2 is provided with and penetrates hole 6, described elastic seal cartridge 3 is provided with sealing hole 7, described penetrate hole 6, seal hole 7 and through hole 5 sets gradually, described sealing hole 7 is cone-shaped, along penetrating hole 6 towards through hole 5 direction in being gradually reduced.During installation, first elastic seal cartridge 3 is encased in containing cavity 4, it is then charged into plug stifled, by fill in stifled elastic seal cartridge carry out top press solidly fixed, penetrate into successively at cable and penetrate hole 6, seal hole 7 and through hole 5, owing to the sealing hole of elastic seal cartridge 3 is taper, therefore, it is deformed by the inner wall deformation of cable extrusion elastic seal cartridge, thus realizing effective sealing.
In the present invention, penetrate hole 6, sealing hole 7 and through hole 5 described in sequentially coaxially to arrange. Penetrate hole 6, sealing hole 7 and through hole 5 sequentially coaxially to arrange, when cable penetrates, it is possible to keep it that stationarity is installed, and be favorably improved the sealing effectiveness of sealing shroud.
In the present invention, being provided with thread groove 8 outside the containing cavity 4 of described shell, described plug blocks up 2 and described thread groove 8 threaded engagement. Plug stifled 2 is threadeded with shell employing, good airproof performance, and stability is high, easy accessibility.
In the present invention, described elastic seal cartridge 3 is made up of elastomeric material. In order to strengthen the sealing property to cable, and elastic seal cartridge 3 adopts elastomeric material to make, and contributes to existing effect in fact and seals.
In the present invention, described elastic seal cartridge 3 is cone-shaped. Elastic seal cartridge 3 generally cone-shaped, easy to process, good airproof performance.
In the present invention, described plug stifled 2 is provided with outwardly extension 9. By arranging extension 9 outside plug stifled 2, convenient operation when contributing to using.
Embodiment is not construed as the restriction to invention, but any spirit based on the present invention is made
Improvement, all should within protection scope of the present invention.
