Stage structure
The invention discloses a stage structure comprising a rocket body, a pneumatic reduction mechanism and a pneumatic anti-collision mechanism. The pneumatic reduction mechanism comprises a pneumatic head and an ablation resisting layer. The pneumatic head is a second gas bag capable of being shrunk and spread. The second gas bag covers the head of the rocket body. The pneumatic anti-collision mechanism is provided with a first gas bag capable of being shrunk and spread. The first air bag covers the tail of the rocket body. After being inflated, the second gas bag is of a symmetrical structureand has good pneumatic stability. The outer wall of the second gas bag is provided with an ablation resisting layer, so that the second gas bag cannot be burned during flying aloft at high temperature. The second gas bag can reduce the speed of the rocket body at high temperature in high altitude; besides, during landing in low altitude, the second gas bag can achieve a buffering function on the rocket body; the second gas bag has the foldable capacity, so that the occupied space on the rocket body and the weight of the second gas bag can be reduced. Meanwhile, the first gas bag can achieve the flexible buffering function on the tail when the tail of the rocket body lands, and therefore the rocket body is prevented from being damaged.

Anti-slurry-pollution method for spray tower observation window
ActiveCN107327259ADoes not affect airtightnessNo need to change the structureDoor/window applicationsWindow cleanersAgricultural engineeringSlide plate
The invention discloses an anti-slurry-pollution method for a spray tower observation window. The anti-slurry-pollution method comprises the following steps that an inner sliding plate and an outer sliding plate are installed, the left sides and the right sides of the inner sliding plate and the outer sliding plate are provided with limiting devices, an inner sliding plate cleaning part is installed, a spray preparing phase is observed, spray is observed, and the upper half part of an inner transparent plate is cleaned. According to the anti-slurry-pollution method for the spray tower observation window, under the premise that an existing spray tower body structure is not changed and the gas-tightness of a spray tower is not influenced, a spray rod, a nozzle angle and the spray effect are observed conveniently through an existing observation window, the observation effect of the observation window is clear, and the observation window is not prone to being polluted.
