Description
Technical field
The utility model relates to a kind of water column impelling cylinder, relates in particular to a kind of high speed water column inertia impelling cylinder.
Background technology
Development and use along with various rigid padded coamings (such as rubber, rigid aluminium etc.), cushion cylinder or cylinder etc., the buffering of high speed load and recovery technology be comparative maturity, so that the application of inertia impelling is very extensive, such as aircraft carrier ejector, various weighted platforms etc.The impelling cylinder drives cut after parabolic obtains certain initial velocity, treats that parabolic realizes emission process under the effect of inertia.The water column inertia impelling of existing water column impelling cylinder goes out in the process of impelling cylinder, owing to be structure as a whole between cylinder base and the upper shell or be fixedly connected with, so after water column begins impelling, negative pressure will be formed on impelling cylinder bottom, this negative pressure will cause the destruction of shape in the interior water column course of injection of impelling cylinder, even can't eject with the form of water column.
Summary of the invention
The purpose of this utility model impelling cylinder bottom when being to provide a kind of water column impelling in order to address the above problem does not have the high speed water column inertia impelling cylinder of negative pressure.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises upper shell, cylinder base and spacing ring, the upper end-face edge of described cylinder base is evenly distributed with the cylinder base projection that raises up, form groove between the adjacent described cylinder base projection, the lower edge of described upper shell is evenly distributed with the upper shell projection of outside projection, described upper shell projection places in the described groove, the thickness of described upper shell projection is less than the height of described cylinder base projection, and described spacing ring is set in the upper surface of described cylinder base boss.Under power source promotes, impelling cylinder integral body is straight up motion in bore, when beginning the buffering recovery, because the height of cylinder base projection and the thickness of upper shell projection is poor, cylinder base and spacing ring at first are cushioned material and block, stop to move upward, water and upper shell in the impelling cylinder continue to move up under the effect of inertia, holder is opened between upper shell and the cylinder base, and the water column bottom is communicated with atmosphere, thereby has avoided forming negative pressure in the water column bottom, when running into spacing ring, the upper shell projection also stops to move upward, water in the cylinder continues to move upward under effect of inertia, until the impelling cylinder of all dishing out, the emission process of realization water column.
Further, described spacing ring is connected with described cylinder base projection by screw, and described upper shell projection can be in axial direction mobile between the groove that forms between the cylinder base projection and spacing ring.Because spacing ring passes upper shell, is installed on the cylinder base projection upper surface, makes can not hold in the palm fully between cylinder base and the upper shell and holds, be convenient to the impelling cylinder and repeat to install and whole taking-up.
Described spacing ring comprises the rubber ring of lower end and the spacing steel loop of upper end.Begin buffering when reclaiming when whole impelling cylinder runs into padded coaming, cylinder base and spacing ring at first are cushioned material and block, and the upper shell projection impinges upon on the rubber ring of spacing ring lower end subsequently, thereby effectively the spacing steel loop of protection upper end is not damaged.
Contact-making surface between described upper shell and the described cylinder base is taper surface.Assemble and separate for the ease of automatically repeating between upper shell and the cylinder base, both contact-making surface places are designed to pyramidal structure, and contact-making surface place, upper shell bottom is cone boss, and cylinder base contact-making surface place is conical socket.
Be provided with the O RunddichtringO on the taper surface that contacts between described upper shell and the described cylinder base.Arrange by O type seal groove on the cone boss circumferencial direction of upper shell bottom contact-making surface, place the O RunddichtringO in the groove, utilize the weight of upper shell self that the O RunddichtringO is compressed, prevent the leaked water in the impelling cylinder.
Described cylinder base projection and described upper shell number of slugs are equal, between the two arranged in dislocation.
Little 2cm～the 10cm of height of the described cylinder base projection of the Thickness Ratio of described upper shell projection; The best is 8cm.
The beneficial effects of the utility model are:
The utility model adopts separate type by upper shell and cylinder base, goes out in the process of impelling cylinder at water column, and the bottom of impelling cylinder is communicated with atmosphere, eliminates the negative pressure bottom the impelling cylinder, thereby has realized the emission process of regular water column.Concrete advantage is as follows:
1, the impelling cylinder is separate type in the utility model, can separate between upper shell and the cylinder base, realizes in the water column emission process, and the water column bottom communicates with atmosphere, thereby has avoided the impact of water column bottom negative pressure on the water column shape.
2, impelling cylinder upper shell and cylinder base all are designed to the arranged in dislocation projection cube structure, and the bump height on the upper shell is lower than the bump height on the cylinder base, can realize that upper shell separates automatically with cylinder base in the bump removal process.
3, the contact-making surface place of impelling cylinder upper shell and cylinder base is designed to pyramidal structure, between place the O RunddichtringO, utilize the weight of upper shell self that sealing ring is compressed, prevent the leaked water in the impelling cylinder.
4, by spacing ring is set, can self-return after impelling cylinder bump reclaims, realize that the impelling cylinder reuses and be convenient to whole the taking-up.
