[0031] Preferred embodiments, in combination Figure 3-6 As shown, the control lock 3 includes a housing 4, a rotating arm 5, and a latch 6. The housing 4 is fixed to the upper edge of the protective body 1. A drive assembly 7 is located below the housing 4. A channel 401 is located above the housing 4, and rotating arms 5 are arranged on both sides of the channel 401. The rotating arms 5 are L-shaped, and their lower ends are connected to the housing 4 by a pivot. A contact plate is located at the bottom of the rotating arm 5, which contacts the drive assembly 7. A telescopic head 501 is located at the upper end of the rotating arm 5, which enters the channel 401 and can be displaced when compressed.

[0036] Working principle: First, close the control lock 3 to connect the protective body 1 and the top cover 2. Then, inflate the protective body 1 to make it stand upright. Enter the protective body 1 through the door 102. The protective body 1 has a grounding hole at the center of its bottom surface. Install a grounding wire in the grounding hole. Place the hydrogen balloon into the protective body 1 and connect it through the air hole 101. Fix the protective layer 103 with the fixing ring 104. Then, fill the hydrogen balloon with hot hydrogen. After reaching the required pressure, connect the radiosonde to the rope at the bottom of the hydrogen balloon. Then, operate the control lock 3 remotely to open the top cover 2. With the help of the steel wire rope 202, pull open the top cover 2 and the protective cloth to allow the hydrogen balloon to safely ascend and conduct field meteorological observation.

[0037] Multiple control locks on the protective body 1, with the lower part of the protective layer secured by fixing rings, allow the control lock 3 to be remotely opened when needed, releasing the restriction on the top cover 2 and automatically launching the hydrogen balloon and radiosonde. This device can still be used in strong winds (above level 8), and does not require multiple people to protect the balloon; one person can complete the operation. During inflation, it prevents the balloon from bursting and generating static electricity, avoiding the combustion and explosion of the hydrogen balloon that could injure people. In addition, it solves the problem of balloon bursting due to long distances and strong winds during balloon launch. The balloon is filled inside the protective body, and after inflation, two people can lift the protective body and top cover to the launch point. Once the radar is ready, the automatic balloon launch tent can be remotely controlled from inside the vehicle via computer software, and the balloon is launched synchronously with the radar.

[0038] The steel wire rope 202 above the top cover 2, in conjunction with a rope winding device, such as a winch, can pull up the top cover 2 and open it.

The control locks 3 are installed on the upper part of the cylinder. The mortise locks 6 are attached to the top cover 2 by elastic bands. The mortise locks 6 are inserted into the channel 401 to lock the upper and lower parts. A remote control lock (weighing more than 3 kg) is placed on the canvas inside the protective body 1 to fix the rope holding the balloon. A remote control pull wire device box is located on the ground five meters away from the protective body 1. It is attached to the outside of the top cover by a hook on a steel wire rope. At the same time, the remote control device box also has a control line connected to the protective body. The remote control has four buttons: A, B, C, and D. During operation, press the A, B, and D buttons on the remote control in sequence on the radar vehicle. Pressing the A button opens the three control locks 3 and unlocks the top cover 2. Press and hold the B button to start the reel-in device. When the top cover is pulled down to the appropriate position, release the button to stop the reel-in. Press the D button to open the remote control lock inside the protective body 1, release the balloon cable, and take off with the radiosonde. When the top cover 2 needs to be reinstalled, first unhook it, then place the top cover 2 on the cylinder, align it, and lock it. At this time, pull the hook and press and hold the C button to release the steel wire until the hook can hook the top cover.

[0041] This device consists of two parts: an upper part, a 0.35-meter-high arc-shaped dome (top cover 2), and a lower part, a 2.25-meter-high cylinder (protective body 1). The cylinder frame and the arc-shaped dome frame are constructed using a 10cm diameter cylindrical air column. The frame is covered with two layers of fabric: an outer camouflage fabric for heat insulation, rainproofing, puncture resistance, fireproofing, sun protection, and abrasion resistance, as well as camouflage; and an inner anti-static soft fabric to prevent static electricity from causing combustion or explosion. The bottom of the lower cylinder is covered with thickened canvas for protection. To prevent the balloon from being punctured by sharp objects, the lower cylinder has a zippered door measuring 85cm (width) × 170cm (height) for personnel and equipment to enter, namely the door 102. Above the air column at the bottom of the cylinder, there is an air hole 101 for the inflation tube to extend into the tent. The cylinder is fixed to the ground by six ground pegs at the bottom and six ropes 106 at the top. There is a cloth bag on the outer wall of the cylinder for placing a radiosonde. A conductive thin metal chain, namely the conductive chain 201, hangs under the top cover. One end of the chain will hang down naturally to contact the inflated balloon, and the other end will cross the cylinder and extend to the nearest ground peg.
