Abstract

Disclosed are an automatic remote water supply system in a low gravity environment, which includes a water supply unit, an environment detection unit and a control unit. The water supply unit includes a water bag, an air inlet pipe, a water pipe and a water pump on the water pipe. The bottom of the water bag has an air inlet and a water outlet. The air inlet pipe is communicated with the water bag through the air inlet. The water pipe is communicated with the water bag through the water outlet. The environment detection unit is configured to detect environmental information in the ecosystem to which the water supply system belongs in the low gravity environment. The control unit is configured to control the starting state of the water pump according to the environmental information, so that water in the water bag flows out through the water pipe.

Claims (15)

1 . An automatic remote water supply system in a low gravity environment, comprising:

a water supply unit, comprising a water bag, an air inlet pipe, a water pipe and a water pump provided on the water pipe, wherein the water bag is provided with an air inlet and a water outlet at a bottom of the water bag, the air inlet pipe is communicated with the water bag through the air inlet, and the water pipe is communicated with the water bag through the water outlet;

an environmental detection unit, configured to detect environmental information in an ecological circle to which the water supply system belongs in the low gravity environment, wherein the environmental information comprises temperature and illumination; and

a control unit, configured to control a starting state of the water pump according to the environmental information, so that water in the water bag flows out through the water pipe; wherein

a first blocking medium is provided in a pipeline of the air inlet pipe, the first blocking medium is configured to separate an air inlet from an air outlet of the air inlet pipe, and the first blocking medium is driven to move inside the air inlet pipe through a negative pressure in the water bag created by a water extraction of the water pump; a second blocking medium is provided in a pipeline of the water pipe, the second blocking medium is configured to separate an inlet water from the water outlet of the water pipe, and the second blocking medium is driven to move inside the water pipe; and

lengths of both the first blocking medium and the second blocking medium are configured as lengths of blocking mediums after the pipeline is stabilized for 48 hours and water is not discharged from the water bag.

2 . The automatic remote water supply system in the low gravity environment of claim 1 , wherein the first blocking medium or the second blocking medium is filled according to the following method:

placing the blocking medium in a container with good thermal conductivity and placing the container on a hot water surface; after the blocking medium is melted into a liquid state, using a syringe to extract a liquid blocking medium and injecting the liquid blocking medium into the air inlet pipe or water pipe; then letting the liquid blocking medium stabilize and wait for the blocking medium to slowly cool down, wherein a temperature of hot water is higher than a melting point of the blocking medium.

3 . The automatic remote water supply system in the low-gravity environment of claim 1 , wherein both the first blocking medium and the second blocking medium are made of lipid-like chemicals.

4 . The automatic remote water supply system in the low gravity environment of claim 1 , wherein the water pump is provided on the water pipe close to the water outlet.

5 . The automatic remote water supply system in the low gravity environment of claim 1 , wherein the water pump is an electromagnetic water pump.

6 . The automatic remote water supply system in the low gravity environment of claim 1 , wherein the environmental information comprises temperature and illumination, and the control unit is further configured to:

a, determine whether the temperature is greater than or equal to a preset temperature and whether the illumination is greater than or equal to a preset illumination, in response to that the temperature is greater than or equal to the preset temperature and the illumination is greater than or equal to the preset illumination, start the water pump and proceeding the next step, and in response to that the temperature is less than the preset temperature or the illumination is less than the preset illumination, not start the water pump; and

b, determine whether a water pressure on an outlet side of the water pump is less than a preset pressure, in response to that the water pressure on the outlet side of the water pump is less than the preset pressure, the water pump is configured to stop working, and in response to that the water pressure on the outlet side of the water pump is greater than or equal to the preset pressure, the water pump is configured to work continuously and extract water in the water bag, so that the water flows out from the water outlet of the water pipe.

7 . The automatic remote water supply system in the low gravity environment of claim 1 , wherein the water supply unit further comprises a plastic slot for fixing the water bag, a base for fixing the water pump and tie lines spaced around the water pipe.
