The cable winch 16 can tighten the mooring cable 12, so that the mooring balloon 1 is anchored on the mooring ring 24, and can also release the mooring cable 12, so that the mooring balloon 1 is released from the mooring state and starts to lift off. 16 can be linked or controlled individually.
 The generator 17 and the power supply battery 18 are electrically connected to the mooring cable 3, the main winch 15, and the cable winch 16 to provide system power, and a mains interface is provided. 15 side of the winch (eg figure 2 , 5 shown). Specifically: the generator 17 and the power supply battery 18 are arranged on the back side of the main winch 15 , the gas cylinder 22 is arranged on the front side of the main winch 15 ; the equipment storage box 20 is arranged on the right side of the main winch 15 , the electrical control box 19 is arranged on the left side of the main winch. The front, rear, left, and right above are based on a person sitting in the cab as a reference. The equipment storage box 20 and the electrical control box 19 are located at the upper end of the gas cylinder 22 provided at the bottom of the main winch 15 .
 like figure 1 , 3 As shown, a tearing web 7 is installed on the captive balloon 1, and a safety rope 8 is fastened on the tearing web 7. The safety rope 8 is connected to the mooring cable 3 when the mooring balloon 1 is lifted and suspended, and the safety rope 8 is connected to the load-bearing box 14 when anchored. In emergency situations such as the escape of the tethered balloon 1, the tethered balloon 1 is torn through the safety rope 8, so that the tethered balloon 1 is deflated and quickly falls to the ground.
 The mooring balloon 1 is installed with a cable assembly, and the cable assembly includes a shape cable 9 , a hanger cable 10 , a windbag cable 11 and a mooring cable 12 . The forming cable 9 converges from the top of the balloon along the rope loop on the ball to the mooring point of the mooring cable 3 under the ball, and the balloon is drawn into a full shape by the tension of the forming cable 9 . One end of the hanger cable 10 is connected to the mooring balloon 1 , and one end is connected to the hanging point of the load hanger 6 . One end of the windbag cable 11 is connected to the bottom of the windbag tail 5 , and one end is connected to the mooring point of the mooring cable 3 or the formed cable 9 , for restricting the movement of the windbag tail 5 . The number of the mooring cables 12 corresponds to the number of the mooring brackets 25 and the cable winches 16 . The three mooring cables 12 are evenly distributed on the side surface of the mooring balloon 1 , and the lower ends of the three mooring cables 12 are connected to the mooring cable winch 16 for mooring the mooring balloon 1 .
 The load pylon 6 is internally provided with a power conversion module and a structural interface, and is electrically connected with the mooring cable 3 and the task load 2 . The upper side of the load hanger 6 is provided with three hanging points evenly distributed above the load hanger 6, two of which are connected to the mooring balloon 1 through two hanger cables 10, and the other hanging point is connected to the tethered balloon 1. At the mooring point of the mooring cable 3.

According to the load requirements, it can also be in other shapes.
 The mission load 2 includes cameras, communication equipment, lighting loads, etc., and the type and combination of loads are also selected according to usage requirements. The task load 2 is installed on the lower side (bottom) of the load rack 6, and can also be installed in other positions according to the requirements of use.
 The mooring cable 3 selects a power supply composite cable or a photoelectric composite cable, one end of which is connected to the main winch 15, and the other end is connected to the mooring balloon 1 through a formed cable 9, which is used for pulling and mooring the balloon 1, and providing equipment on the ball. For power transmission, it can also be used for communication between the mooring balloon 1 and the ground when the optoelectronic composite cable is selected.
 When performing the task, the anchor car 4 is powered on through the mains or generator 17, the mooring balloon 1 is deployed near the load-bearing box 14, the main winch 15 is activated to release the mooring cable 3, and the mooring cable 3 passes through the mooring ring 24. Connect with the mooring balloon 1, connect the mooring balloon 1 and the inflation tube to inflate, transfer the mooring balloon 1 to the top of the mooring car 4 after the inflation is completed, unfold the mooring arm 25, and pass the end of the mooring cable 12 through the guide wheel 26 is connected to the cable winch 16, controls the cable winch 16 to recover the mooring cable 12, lowers the height of the mooring balloon 1 until the operator can reach the pylon cable 10, installs the load pylon 6 and the task load 2, in turn Release the mooring cable 12 and mooring cable 3, so that the mooring balloon 1 is gradually lifted to the working height and enters the information support state.
 During the task waiting process or after a single task is completed, when the main winch 15 is controlled to recover the mooring cable 3 to near the ground, the end of the mooring cable 12 is connected to the cable winch 16 through the guide wheel 26, and the cable winch 16 is controlled to recover Tie down the mooring cable 12, lower the mooring balloon 1 until it is in contact with the mooring ring 24, and connect the bottom tab of the mooring balloon 1 to the mooring ring 24 to assist in fixing the mooring balloon 1. During the descending process of the mooring balloon 1, the entire mission load 2 and the load hanger 6 are placed on the load bracket 21.
 When the mission is no longer performed, remove the mission load 2 and put it into the packing box, deflate the mooring balloon 1, disconnect it from the mooring cable 3, fold it and place it on the anchor car 4, fold the mooring arm 25, and the system is disconnected. Electricity can be transported or stored.
