Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] A bladder type storage tank indicator device used in a microgravity environment, the bladder 4 is provided in the housing of the bladder tank 3, the upper end of the housing is provided with a liquid port 2 for replenishing liquid into the bladder 4, and the lower end of the housing is provided with a bladder 4 The air port 8 inflated between 4 and the housing also includes a liquid port Hall element 1 arranged near the liquid port 2, an air port Hall element 9 arranged near the air port 8, and n magnets 5 arranged at the bottom of the bladder 4 ; n is an integer not less than 5.

[0022] The magnetic steel 5 is arranged on the surface of the bottom of the leather bag 4 facing the air port 8; wherein, a circular area is divided on the surface with the center of the bottom of the leather bag 4 as the center of a circle, and a central magnetic steel 5...

Abstract

The invention discloses a bag-type storage box indication apparatus for a microgravity environment. A leather bag is arranged in a shell of the bag-type storage box, a liquid opening which is used for supplementing liquid into the leather bag is formed in the upper end of the shell, an air opening which is used for charging air between the leather bag and the shell is formed in the lower end of the shell, a liquid opening hall element is arranged nearby the liquid opening (2), an air opening hall element is arranged nearby the air opening, and the bottom of the leather bag is provided with n pieces of magnetic steel; a hall element measurement storage box empty-full indication apparatus can be used for indicating the empty state and full state of the bag-type storage box, by adopting a hall probe and the magnetic steel, whether a signal is sent out or not is determined according to the distance between the magnetic steel and the probe, both the magnetic steel and the hall probe do not contact a storage medium, the medium is prevented from being polluted; moreover, the hall probe and the magnetic steel are small in size and light in weight, so that the additional weight is light; meanwhile, the hall probe is accurate in signal indication, and the empty and full situation of liquid in the storage box can be effectively tested.

Description

technical field [0001] The invention relates to the field of microgravity measurement, in particular to a Hall element-based capsule storage tank empty and full indication device, which is used to send a full or empty indication when the filling and discharge of the storage tank are about to be completed in a microgravity environment. signal indication. Background technique [0002] The measurement of the remaining liquid in the storage tank is a difficult problem in the design of the storage tank. Due to the irregular distribution of the liquid in the space microgravity environment, it is impossible to accurately measure the liquid interface. Bladder storage tanks sometimes need to be repeatedly added when the space is used. During the process of adding and discharging, it is necessary to measure the empty and full of the storage tank, so as to facilitate the start and stop of adding and discharging. At present, the bladder tanks used in orbit in China do not have empty an...
