Referring to fig. 1-5, in an embodiment of the present utility model, a multi-stage water rocket separating device, a separator assembly includes an inner sleeve 1 and an outer sleeve 2, the outer sleeve 2 is movably sleeved outside the inner sleeve 1, the upper portion of the inner sleeve 1 is connected with a water rocket upper rocket body, the lower portion of the inner sleeve is provided with an inner sleeve base 13, the inner sleeve base 13 is provided with a first through hole 12, the side wall of the inner sleeve is uniformly provided with a second through hole 14, balls 11 are installed in the holes, the outer sleeve 2 is provided with a first step surface 21 along the inner circumference, and since the inner sleeve 1 and the outer sleeve 2 are relatively movable, when the outer sleeve 2 moves upwards, the first step surface 21 presses the balls 11 installed in the second through hole 14, in order to prevent the first step surface 21 from falling off from the second through hole 14 when the balls 11 are pressed, and the diameter of the balls 11 in this embodiment is required to be larger than the diameter of the second through hole. The inner sleeve 1 and the outer sleeve 2 required here cannot be completely disengaged during the relative movement, so that a clamping spring 15 is provided between the inner sleeve 1 and the outer sleeve 2, the clamping spring 15 being able to now be disengaged from the inner sleeve 1 by the outer sleeve 2.
The lower part of the inner sleeve 1 is abutted with a supporting piece 3, the supporting piece is composed of a base 31 and supporting columns 32, the number of the supporting columns 32 is the same as that of the first through holes 12, the number of the supporting columns 32 and the first through holes 12 in the embodiment is four, and the supporting columns 32 penetrate through the first through holes 12 to be abutted with the bottom of the outer sleeve. The supporting member 3 is mounted in the base assembly and can freely move, the base 31 of the supporting member 3 is abutted against the bolt cap 41 of the connecting bolt 4 in the base assembly, the connecting bolt 4 is mounted in the outer barrel 5 of the base assembly and can move in the outer barrel 5, the inner wall of the outer barrel 5 is provided with a second step surface 51, the bolt cap 41 of the connecting bolt 4 is positioned on the second step surface 51, and the second step surface 51 limits the moving range of the connecting bolt 4. When the connecting pin 4 moves upward under the action of pressure, the pin cap 41 pushes the base 31 of the support member, so that the support column 32 pushes the outer sleeve 2 through the inner sleeve 1, and the outer sleeve 2 moves upward, so that the step surface 21 applies a pressing force to the balls 11.
The inner sleeve base 13 is fixedly connected with the outer cylinder 5 of the base assembly, and the inner sleeve base 13 can bear pressure from the lower part of the inner sleeve base, so that the inner sleeve base and the outer cylinder 5 are firmly connected to be ejected under the action of pressure, and ultrasonic welding or strong glue bonding can be used. In the whole operation process of the separating device, the inner sleeve 1 and the outer sleeve 5 always keep a relatively static state, the connecting bolt 4 pushes the supporting piece 3 to move, the supporting piece 3 pushes the outer sleeve 2 again, the outer sleeve 2 moves upwards relative to the inner sleeve 1, so that extrusion force of the step surface I21 to the balls 11 is generated, the step surface I21 in the embodiment is a sloping surface, and the sloping surface is arranged because the step surface is smoother when extruding the balls 11, and clamping stagnation is not easy to occur.
The lower part of the connecting bolt 4 is connected with a lower water rocket, so the bolt 42 part of the connecting bolt is also provided with a sealing ring 43 to prevent water leakage and air leakage.
The inner sleeve 1 is connected with an upper water rocket, in this embodiment, a sealing structure is not arranged in the inner sleeve 1, and the sealing structure can be arranged at the joint of the upper water rocket body.
The outer sleeve 2 is further provided with a limit bump 22, the outer sleeve 2 can rotate relative to the inner sleeve 1, when the limit bump 22 rotates to the position of the through hole II 14, the limit bump 22 applies extrusion force to the ball 11, the ball 11 protrudes towards the inner part of the inner sleeve 1 and serves as a safety mechanism, when the outer sleeve 2 is required to be launched after the preparation work is finished, the limit bump 22 is enabled to be staggered from the position of the through hole II 14, namely, safety is relieved, and normal launching can be performed.
As an embodiment of the utility model, a return spring 6 is provided between the inner sleeve 1 and the cap 41, the return spring 6 not producing a substantial force against the compression of the balls 11, which acts to return the parts to their rest position after the firing has been completed.
Before the water rocket is launched, the water rocket needs to be filled with water and pressurized, before the water rocket is not pressurized, the ball 11 arranged in the through hole II 14 is in a free state, the upper water rocket body is connected with the inner sleeve 1, at the moment, the water rocket body can be easily separated from the inner sleeve 11, the joint of the upper water rocket body and the inner sleeve 1 is provided with a boss structure, the boss structure is a conventional design in the field, the connection is not in the protection scope of the patent, and the water rocket is not described in detail in the prior Chinese patent CN202715249U of the inventor. The lower part of the connecting bolt 4 is connected with the lower water rocket body, the lower water rocket body is pressurized at first, the pressure born by the connecting bolt 4 is the same as the pressure in the water rocket body, therefore, under the action of the pressure, the connecting bolt 4 moves upwards relative to the outer cylinder 5, the connecting bolt 4 pushes the supporting piece 3, the supporting column 32 of the supporting piece 3 pushes the outer sleeve 2 to move upwards, the step surface 21 presses the balls 11, the balls 11 protrude inwards to form a locking mechanism, and the inner sleeve 1 and the upper water rocket body form locking connection. After the lower water rocket is pressurized, pressurizing the upper water rocket body.
After the pressurization of each level of rocket body is completed, the rocket body is launched, in the flying process of the rocket, firstly, the lower level rocket body provides flying power, after the lower level rocket body loses pressure, the lower level rocket body does not have pressure on the connecting bolt 4, the step faces 21 are linked, the extrusion force on the balls 11 is also lost, and because the upper level rocket body also has pressure at this time, the upper level rocket is separated from the inner sleeve 1 under the action of the pressure of the upper level rocket body, and the separation of the rocket is completed.
The separation device can expand the stage number of the water rocket, has simple structure, easy pressure control and high success rate.
