Description

Technical Field

[0001] The utility model belongs to the field of microgravity, and specifically relates to a microgravity test bench. Background Art

[0002] Microgravity, also known as zero gravity, is not caused by the gravity of the earth, but is caused by factors such as the residual atmosphere in space. Strictly speaking, it should be "zero weight" rather than zero gravity.

[0003] The patent application with publication number CN113697135A discloses a microgravity deployment device, including: a gantry, a servo hoist assembly and a hanging structure; the servo hoist assembly is installed on the top of the gantry, and the servo hoist assembly balances the weight of the object to be measured while following the movement; the hanging structure includes a wire rope, a movable pulley, a center of mass lead-out hanging structure and a whole-wing lifting frame, the wire rope is lifted with the servo hoist, the wire rope is wound on the movable pulley, and the two servo hoists are subjected to the same force through the rolling of the movable pulley, the bottom of the support frame of the movable pulley is connected to the center of mass lead-out hanging structure, the center of mass lead-out hanging structure is connected to the whole-wing lifting frame through a two-dimensional adjustment shaft, and the whole-wing lifting frame is connected to the object to be measured. The present invention can effectively solve the ground simulation deployment problem of a certain type of space station large-load mechanism, and has the functions of large-load gravity balance, following movement, etc.

[0004] However, the above-mentioned comparative documents have the following disadvantages when used:

[0005] From the description in paragraph 0038 of the above-mentioned comparative document that "the servo hoist assembly 2 is installed on the top of the gantry 1, and the hanging structure 3 and the object to be measured 4 are unloaded by gravity as a whole through the servo hoist assembly 2", it can be seen that the test piece needs to be clamped and lifted by the hanging structure 3. Since the existing hanging structure 3 has a complex structure and high cost, and due to technical limitations, the object will generate a lot of friction during the falling process, which leads to large errors in the experimental data obtained, which can no longer meet people's needs.

[0006] Therefore, a microgravity test bench is proposed to solve the above drawbacks. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a microgravity test platform.

[0009] A microgravity test bench comprises an operating panel, wherein two inclined grooves are provided on the upper side of the operating panel, one end of the two inclined grooves are connected, and a collecting tube is connected to the bottom of the inclined groove;

[0011] The sample matched with the inner wall of the suction cup facilitates the adsorption of the sample by the suction cup.

[0012] Optionally, two through holes are provided on the upper side of the operating panel, and the adjacent through holes are connected to the inclined groove. A C-shaped plate is installed inside the inclined groove to facilitate the installation of the C-shaped plate on the inclined groove. The upper end of the collecting tube is located below the through hole, and the other ends of the two collecting tubes are connected.

A motor is installed inside the slideway, which facilitates the installation of the motor inside the slideway. One end of the threaded rod is installed on the output end of the motor, which facilitates the installation of one end of the threaded rod on the output end of the motor. Two sliding blocks are installed on the U-shaped plate, which facilitates the installation of the sliding block on the U-shaped plate. The sliding block is slidably fitted inside the slideway, which facilitates the sliding block to slide inside the slideway. The stability of the sliding block is improved when sliding.
