DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] As Figures 1-5 shown, a vacuum pumping tank for simulating Mars dust ejection includes a tank body 1, the tank body 1 is installed on a base 2, dry ice can be installed at the bottom end inside the tank body 1, an air outlet valve pipe 7, a gas guiding valve pipe 4, a data detector 8 and a pressure gauge 6 are installed at the top end of a cover body 3 on the top of the tank body 1, the gas guiding valve pipe 4 is connected to a vacuum pump 5 installed on the top of the base 2 through a conduit, a sand spraying device 9 is installed on the top of the base 2, and the spraying end of the sand spraying device 9 is connected to one side of the tank body 1 through a sealed valve pipe. Two irradiation lamps 10 are symmetrically installed at the bottom of the cover body 3, a temperature regulating component is installed on the tank body 1, and a temperature sensor 15 is installed on the outer wall of the tank body 1.
[0022] When this device simulates the Mars environment, dry ice is put in through the sealable inlet at the top of the cover body 3, then the inlet is closed, the valve of the gas guiding valve pipe 4 is opened to start the vacuum pump 5, the inside of the tank body 1 is pumped to a vacuum, and the dry ice volatilizes to form carbon dioxide to simulate the atmospheric composition. Finally, the irradiation lamps 10 are started to simulate solar irradiation, and the temperature is reduced through the temperature regulating component to simulate the temperature of different time periods on Mars. Then the temperature sensor 15 and the pressure gauge 6 are started to carry out integrated monitoring. When the internal pressure is about 600 - 700 Pascals, it meets the standard, ensuring that each parameter is kept within the set range to simulate the stability of the Mars dust environment. Airflow can also be introduced according to needs by installing a fan inside or an air inlet pipe on the side wall to simulate the wind on Mars. A certain amount of fine sand is sprayed into the tank body 1 through the sand spraying device 9. Finally, various data during the experiment, including pressure, temperature, wind speed, dust concentration, etc., are recorded by the data detector 8 to complete the experimental detection. Then the performance and durability of the Mars rover can be effectively and accurately evaluated. After completion, the valve of the air outlet valve pipe 7 is opened to discharge carbon dioxide.
[0023] See Figure 3 , the temperature regulating component includes a spiral liquid nitrogen pipeline 14 passing through the side wall of the tank body 1 at both ends. The spiral part of the spiral liquid nitrogen pipeline 14 is inside the tank body 1, and the docking ports at both ends are outside. A liquid nitrogen generator 13 is installed on the top of the base 2, and the outlet and inlet of the liquid nitrogen generator 13 are docked with the two interfaces of the spiral liquid nitrogen pipeline 14.
[0024] By designing a temperature regulation component, since the temperature on Mars is relatively low and cooling treatment is required, liquid nitrogen can be produced by a liquid nitrogen manufacturing machine 13 at this time and enter the spiral liquid nitrogen pipeline 14. The spiral liquid nitrogen pipeline 14 will absorb a large amount of heat inside the tank body 1, effectively reducing the internal temperature to about minus sixty degrees, which is very convenient. It should be noted that the connection between the liquid nitrogen manufacturing machine 13 and the spiral liquid nitrogen pipeline 14 is an existing design, and its detailed principle will not be elaborated.
[0025] An auxiliary electric heating tube 11 is installed inside the tank body 1, and the auxiliary electric heating tube 11 is electrically connected to a controller 12 on the outer wall of the tank body 1.
[0026] Furthermore, when heating is required, since reducing the power of the liquid nitrogen manufacturing machine 13 results in slow heating by the irradiation lamp 10, the auxiliary electric heating tube 11 can be separately started by a separate controller 12 at this time for additional radiant heat conduction heating, which is very practical. It should be noted that in this case, other devices all have shared or independent start controllers, which will not be elaborated here.
[0027] See Figures 3-4 , a bracket 17 is installed on the top of the base 2, a ring plate 16 is fixed at the top of the bracket 17, the ring plate 16 is nailed to four angle iron plates 18 fixed to the outer wall of the tank body 1, and a gasket 19 is stuffed between the ring plate 16 and the angle iron plates 18, and the gasket 19 is also nailed to the ring plate 16 and the angle iron plates 18.
[0028] During installation, place the gasket 19 at four installation positions on the top of the ring plate 16, and then lift and place the tank body 1 inside the bracket 17, and the angle iron plates 18 are placed on the gasket 19. At the same time, the screw holes of the angle iron plates 18, the gasket 19, and the ring plate 16 correspond, and then installation can be carried out by screws, which is very convenient and stable.
[0029] An extension rod 20 is fixed to the side wall of the ring plate 16, and a display screen 21 is connected to the extension rod 20 by a clamp. Furthermore, the display screen 21 is electrically connected to the temperature sensor 15, the data detector 8, and the pressure gauge 6 in this device, and then the detected and collected data can be limited for convenient viewing.
[0030] This is the working principle of this kind of Mars dust injection simulation vacuum tank.
[0031] The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art.
