Problems solved by technology
[0004] At present, the connection of antenna tension cables at home and abroad is mainly connected directly to the antenna structure. In space, the tension changes greatly due to the influence of temperature, which leads to the deterioration of the stability of the antenna cable network system and the antenna profile.

Embodiment Construction
[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0026] like figure 1 Shown is the exploded view of the structure of the nearly constant tension compensation device of the tension cable of the present invention, figure 2 Shown is the structural assembly drawing of the nearly constant tension compensation device of the tension cable of the present invention. It can be seen from the figure that the compensating device is composed of six parts: a first connecting piece 1, a sliding sleeve 2, a sliding column 3, a compression spring 4, two stop pins 5 and a second connecting piece 6, wherein the first connecting piece 1 is used to connect The external antenna rigid structure, the second connecting piece 6 is used to connect the external antenna tension cable, the specific connection relationship of the compensation device is as follows:
[0027] The first connecting piece 1 includes two lugs wi...

The invention relates to a tension cable close constant tension compensation device, comprising a first connector, a slide sleeve, a slide pillar, a compression spring, two stop pins and a second connector; the first connector is connected with an antenna rigid structure; the second connector is connected with an antenna tension cable; the first connector is connected with the slide sleeve to enable the slide sleeve to freely rotate around the connection position, so the angle change demands when the antenna tension cable is adjusted are met; one end of the compression spring is fixedly arranged at the large-diameter end of the slide pillar and is sleeved at the small-diameter end of the slide pillar; the slide pillar and the compression spring are assembled in the slide sleeve; the two stop pins are fixedly connected with the slide pillar and can freely slide in a stop pin slide slot formed at the slide sleeve; the second connector is fixedly connected with one end of the small-diameter section of the slide pillar, so the tension change of the antenna tension cable is transmitted to the compression spring. The compensation device can overcome the huge tension change of the tension cable under the space temperature change, and the tension stability of the tension cable is kept.
Description
technical field [0001] The invention relates to a near-constant tension compensation device for a tension cable. The invention provides a way to maintain the stability of the pretension of the antenna tension cable under the condition of space temperature variation, and belongs to the technical field of mechanisms. Background technique [0002] The cable net system is an important part and key component of a large-scale mesh deployable antenna. It is mainly composed of flexible tension cables, which are connected to the main body of the antenna structure in a certain way, and the required antenna profile is formed through design. [0003] Among them, the stability of the pretension of the tension cable in the cable net system has a great influence on the forming and maintenance of the antenna profile, the stiffness of the cable net system, the gravity deformation of the cable net system, the temperature deformation of the cable net system, and the deployment power of the ante...
