Problems solved by technology

However, the efficiency of this device is low, and it takes 45 days to perform a mission to return to normal
In addition, this kind of device has a single purpose, the revolution speed of the device is 7.9km / s, the linear rotation speed is 1.2km / s, the revolution speed obtained after the load rotates half a circle is the revolution speed of the device plus the linear rotation speed It is 7.9+1.2=9.1km / s, only this value can be obtained and other revolution speeds cannot be obtained
The device also does not have the function of adjusting the rotation speed

Embodiment 11

[0069] A variable diameter device works in space. The reducing device is made up of battery 42, converter, 3 winches. Each hoist winds a cable 4 . Such as figure 1 As shown, the battery 42 and each motor 43 are connected to the converter 41 . The converter is used as a transmission device to realize electric transmission, and electric energy can be freely transmitted between the battery 42 and each motor 43 .

[0070] Between the winch and the winch, and between the winch and the battery 42, the electric drive is realized through the converter, so as to transmit power and energy. For example, the cable 4 wound by the first hoist is connected to the first object, and the first object moves outward, the centrifugal force of the first object drives the motor 43 to generate electric energy, and the electric energy is converted by the converter 41 to drive the second hoist, The second hoist winds the cable 4 and pulls the second object to move inward. Conversely, if it is move...

Embodiment 12

[0072] Such as figure 2 Shown, winch is made up of reel 44, axle etc. The axles of the reels of two adjacent winches are collinear, two reels 44 are at two ends, two motors 43 are in the middle, and two motors 43 merge into a double-rotor motor. Each rotor 33 of the dual-rotor motor is respectively connected to a reel 44, and the stator 32 is connected to the machine base.

[0073] The reel 44 is equipped with a Simpson planetary gear transmission to change speed, and the motor drives the reel through the speed changer. There are 3 gears in the transmission, the minimum transmission ratio is 2, and the maximum transmission ratio is 20.

Embodiment 13

[0075] Such as image 3 As shown, the reel 44 adopts the ring gear 34, and one reel 44 is connected with four motors 43, and the ring gear meshes with the gear of the motor. The circumference of the ring gear 34 is equally divided into 4 points, and each motor 43 is on one of the points. The torque of the motor is relatively small, while the diameter of the reel is large. This design can well adapt to the characteristics of large reels.

[0076] Such as Figure 4 As shown, the web 45 of the reel 44 protrudes and becomes a spherical segment shape. The reel 44 and the web 45 are a continuous sealing structure, and the inside is filled with high-pressure neon gas 46 with a pressure of 10 MPa. The high-pressure gas can make the drum expand, and it is not easy to be crushed by the twisted cable.

Abstract

The invention provides a rapid diameter changing device, a space cable rotating system and an application method of the space cable rotating system. The space cable rotating system works on a near-ground track, whereinthe height of the near-ground point is lower than 200km, and the space cable rotating system rotates and revolves anticlockwise. The system is composed of a middle cabin and two balance weights, each balance weight is arranged at one end, and the balance weights rotate around the middle cabin. The diameter changing device is utilized in the system, the diameter changing device isprovided with a plurality of winches, transmission can be achieved among the winches, and the other winch is driven by electric power generated by one winch. A cable wound by the winches pulls the balance weight A, the balance weight B, loads and the like to carry out diameter changing, the diameter changing speed can reach 10 50m / s and is several times or above faster than that of a solar powersupply manner, and the time of the high centrifugal force stage is greatly shortened. Through diameter changing, linear speed adjustment can be achieved, and the methods of ascending, descending, forward throwing and the like of the system are achieved.

Description

technical field [0001] The invention belongs to the technical field of space, and in particular relates to a diameter reducing device, a space switching cable system, and an application method thereof. Background technique [0002] Ordinary launch vehicles need to accelerate the load to the first cosmic velocity of 7.7km / s or more before they can send the load into space orbit. The average cost per ton is between millions of dollars, which is very high. The payload refers to spacecraft such as satellites and spaceships. [0003] Tethered satellites are a tried-and-tested technology, and there have been several spaceflight trials. One type of tethered device is eg a device that captures a load and throws it (MXER device). The device consists of a counterweight and cables. The launch vehicle goes up into space with the payload, the payload is docked to the end of the cable, and at the same time the rocket separates, discards, and falls to the earth. This device throws the ...
