The release can be performed at different heights according to the measurement of the height sensor to obtain data of the required height. The sleeve 1 can carry different space detectors according to needs, and collect different information in the same area at the same time for the measurement of the atmosphere, wind speed, temperature, etc. The measurement is convenient, the height can be accurately obtained according to the height sensor, and the unlocking is electrically driven by mechanical means. The structure is simple, the assembly is convenient, the release speed is fast, the stability is good, the reliability is good, and the cost is low.

[0041] Specifically, the assembly process of the electric unlocking and releasing device of the space probe is as follows:

[0042] Step 1) Connecting the two ends of the elastic sheet 14 to the connecting pieces 15 respectively, and each connecting piece 15 is glued to the inner wall of the sleeve 1 by gluing;

[0043] Step 2) Assemble the motor 12 and the chuck 4;

[0044] Step 3) Place the chuck 4 equipped with the motor 12 into the sleeve 1, and the chuck 4 is fixedly engaged with the engaging structure 5 on the inner wall of the sleeve 1. The chuck 4 has a certain weak elasticity, and can be fixedly engaged with the engaging structure 5;

[0049] Step 8) Fix the bottom cover 3 to the sleeve 1 by bolts.

[0050] The process of releasing the space probe by the electric unlocking and releasing device of the space probe:

[0051] The electric unlocking and releasing device of the space probe is transported to a certain height by aircraft or other means, and the measuring height is set. When the height sensor detects the set height, the controller controls the motor to unlock, and the elastic sheet pops out the release cover with the space probe to collect information on the area to be collected.

[0052] like Fig.14 As shown, it also includes a timer, the timer is electrically connected to the controller, and the motor 12 is electrically connected to the timer; the start time can be set by the timer, and when the set time is reached, the controller controls the motor 12 to brake, drive the unlocking disk to unlock, and release the space detector.

[0053] In this embodiment, the gap between the elastic sheet 14 and the corresponding long hole is smaller than the diameter of the space detector, ensuring sufficient elastic force to eject the space detector.

[0054] like Figure 6 , 7 As shown, the mounting bracket 10 of the present embodiment can not only fix the space detector, but also the bottom of each mounting bracket 10 extends to the outside of the release cover 8, and can be used as a snap-in structure to realize the snap-in between the bottom of the release cover and the sleeve 1, thereby ensuring the connection between the bottom of the release cover and the sleeve 1, without adding other structures, to ensure quick release.

[0055] like Figure 2 , Figure 3As shown, the stop structure of this embodiment includes reinforcement plates 13 located on the inner wall of the sleeve 1 and arranged on the left and right sides of each long hole 101.

The inner ends of the reinforcement plates 13 on both sides of each long hole 101 and the lower ends of the cross plate above extend toward the direction of the long hole and are surrounded by stop grooves on the inner walls of the long holes 101. Each release cover 8 is tightly fitted and embedded in the stop groove; the reinforcement plates 13 and the cross plates 16 can reinforce the outer walls of the long holes 101 to avoid deformation problems behind the load-bearing space detector. At the same time, a part of the reinforcement plates 13 and the cross plates 16 extend toward the direction of the long holes 101 to form stop grooves with the inner walls of the long holes 101, which can form a stop for the release plate inside the sleeve to avoid the release cover from tilting inward. The reinforcement plates 13, the cross plates 16 and the sleeve 1 are integrally formed.

[0056] like Figure 5 As shown, the outer wall of the sleeve 1 above each long hole 101 of this embodiment is provided with a plug hole 103 that penetrates the inner wall of the sleeve 1, and the bottom of each plug hole 103 is connected with the corresponding long hole 101, and the horizontal plate 16 located above each long hole 101 is provided with a guide hole 102 corresponding to each plug hole 103 one by one, and the bottom of each guide hole 102 penetrates the bottom of the horizontal plate 16; the lock buckle 9 includes a plug plate 91 that can be inserted into the plug hole 103 and the guide hole 102, and the bottom of the plug plate 91 is connected with The connecting plate 92 and the plug plate 91 are provided with a locking hole 93 which is plugged into the locking pin 11; the design of the plug hole 103 and the guide hole 102 allows the plug plate of the lock buckle 9 to directly enter the sleeve 1 from the plug hole 103 and the guide hole 102 to achieve locking. After unlocking, the plug plate can be directly released from the plug hole 103 and the guide hole 102 without affecting the release of the release cover; at the same time, the connecting plate 92 can also limit the space detector in the longitudinal direction to ensure the stability of the installation of the space detector.

The lower boss 51 and the upper boss 52 are arranged in parallel with each other. The gap between the upper boss 52 and the lower boss 51 is equal to the thickness of the chuck 4. The chuck 4 is made of plastic material; the lower boss 51, the upper boss 52 and the sleeve 1 of this embodiment can be integrally injection molded. The chuck 4 is made of plastic material and has a certain elasticity. When the chuck 4 enters the sleeve, the outer end of the chuck 4 can be clamped between the upper boss and the lower boss. The structure is simple, and quick installation can be achieved and the stability of the clamping can be ensured.

[0061] The outer end of the chuck 4 of this embodiment is provided with arc grooves corresponding to each long hole 101 at intervals, and the upper and lower end surfaces of each arc groove pass through the upper and lower end surfaces of the chuck 4, and the reinforcement plates 13 on both sides of each long hole 101 are located in the corresponding arc grooves.

[0064] In this embodiment, the length of the mounting plate 1002 located outside the release cover 8 is 2-4 cm, which ensures the effect of the clamping connection while preventing the release effect from being affected by being too long.
