Description

Technical Field

[0001] The invention is an improvement on a tethered balloon launching and retracting system, and in particular relates to a tethered balloon cable guide device, which is used for transferring the buoyancy load of the tethered balloon at different positions in the air to the tethered cable. Background Art

[0002] The tethered balloon is lifted off and loaded with mission equipment through buoyancy. The lower part is connected to the ground cable collection device through a tethered cable to achieve the lift and recovery of the tethered balloon. Since the tethered balloon is affected by the wind direction in the air, it will swing, which will cause the tethered cable to swing. In order to ensure that the cable is always constrained by the ground device during the swing process and does not wear the cable, it is necessary to design a cable guide device to constrain the cable. Traditional cable guide devices have the problem of the cable detaching from the V-groove of the guide device, causing the cable to detach from the V-groove, which poses a major safety hazard. Summary of the invention

[0003] Aiming at the problem that the mooring cable is easy to be entangled in the prior art, the present invention provides a moored balloon cable guide device to improve the stability of the cable when the moored balloon is swaying.

[0004] The present invention proposes a tethered balloon cable guiding device for guiding the tethered balloon cable. The cable guiding device comprises a lower guide wheel mounting frame which can rotate around an X-axis. An upper guide wheel bracket rotating shaft in the Z-axis direction is also provided on the mounting seat of the lower guide wheel mounting frame. A lower guide wheel and an upper guide wheel bracket are mounted on the upper guide wheel bracket rotating shaft. A sleeve is supported at the upper end of the upper guide wheel bracket through a rotating shaft in the Z-axis direction. The sleeve has an upper large guide wheel with rounded corners on both sides of the front and rear of the rotating shaft. A pair of upper small guide wheels are symmetrically arranged at the eccentric position of the upper large guide wheel. The tethered cable passes through the sleeve and then bypasses the lower guide wheel.

[0005] Advantageously, the tethered balloon is tied to a tethered cable through a plurality of tethered riggings, and the other end of the tethered cable is wound around a cable-collecting device.

[0006] Advantageously, the upper guide wheel bracket is a frame structure, and the bottoms of the brackets on both sides are mounted on the rotating shaft of the upper guide wheel bracket.

[0007] Advantageously, the lower guide wheel mounting frame comprises opposite support plates, and the upper guide wheel bracket rotation axis is mounted between the support plates.

[0008] The beneficial effects of the present invention are:

[0009] (1) It can restrain the mooring rope from leaving the V-groove

[0010] Compared with the traditional cable guide device, the present invention adds a guide wheel on the upper part of the traditional guide device, and the mooring cable passes through the upper guide wheel through the lower guide wheel. The upper guide wheel has two small rollers to clamp the cable, and the cable will not fall out of the V-groove of the lower guide wheel.

[0011] (2) Can achieve large-angle deflection in both axes

[0012] Based on the fact that the mooring cable does not leave the V-groove during the swing process, compared with the traditional guide device, the device can achieve a large-angle swing with two degrees of freedom. The swing angle of the traditional guide wheel generally does not exceed 45 degrees, and the present invention can achieve a swing angle of 70 degrees.

[0013] (3) This structure can improve the safety of tethered balloons

[0014] Based on the large swing angle design, the large swing requirements of tethered balloons in strong winds under extreme conditions can be met, which broadens the use boundaries of tethered balloons and improves the safety of tethered balloon use.

[0015] (4) The structure has certain economical

[0016] Based on the improvement of the safety of the tethered balloon, the structure has certain economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] 1. Connection between the cable guide device, the tethered balloon and the cable collection device

[0023] The mooring cable 3 is installed in the cable guide device 4. The cable guide device 4 guides the force transmission direction of the mooring cable 3, and transmits the buoyancy of the moored balloon 1 to the cable collection device 5 through the mooring rigging 2.

[0024] 2. Cable guide device structure

[0025] The cable guide device 4 includes an upper structure and a lower structure, the upper structure is composed of an upper large guide wheel 6, an upper small guide wheel 7 and an upper guide wheel bracket 8, and the lower structure is composed of a lower guide wheel 9, a lower guide wheel mounting frame 10 and an upper guide wheel bracket rotating shaft 11.

[0026] 3. Cable guide function

[0027] The cable guide device 4 rotates around the X-axis through the lower guide wheel mounting frame 10, and the upper guide wheel bracket rotates around the Z-axis through the upper guide wheel bracket rotation axis 11. The Y-axis movement can be achieved through the anchoring vehicle, so the cable guide device 4 can fully meet the design requirements. When the mooring cable 3 has a tendency to rotate around the X-axis, the arc section on the side of the upper large guide wheel 6 can meet the swing function of the mooring cable 3 and will not wear the mooring cable 3. It can solve the technical bottleneck of the small swing angle and limited use of the traditional cable guide device, and lay a technical foundation for the development of large military and civilian aerostats.
