Description

Technical Field

[0001] The present invention relates to the technical field of meteorological detection devices, and specifically to a magnetic force controlled automatic release device for meteorological balloons. Background Art

[0002] In a balloon made of rubber, hydrogen or helium with a density smaller than that of air is filled to carry an instrument into the air, which can be used for meteorological observation and detection of the atmospheric temperature, humidity, wind direction, wind speed and air pressure at high altitudes. These meteorological data are the basic basis for weather forecasting. Since the moment of releasing the balloon and the starting time of the sounding software need to be synchronized, currently conventional detection requires two people to cooperate. One person operates the computer balloon releasing software in the control room to control the sounding radar, and the other person releases the sounding balloon outdoors. The cooperation of two people not only wastes manpower, but also inevitably causes a time difference in the operation of the two people, resulting in inaccurate detection.

[0003] Therefore, a device can be used to replace the person who releases the sounding balloon outdoors, enabling one person to complete the work that originally required two people, saving half of the manpower. Therefore, through the existing evolution, a mechanical release device has emerged. However, the mechanical release device also has several problems: 1. The mechanical device still requires a certain buckle structure to limit the meteorological balloon; 2. Meteorological balloons are generally relatively large. The mechanical release device simply removes the limitation on the meteorological balloon and allows it to be freely released, and the balloon is easily interfered; 3. Before the meteorological balloon is released, the meteorological balloon will be affected by the wind, and the wind will cause the balloon to swing strongly from side to side, making it difficult to achieve precise release. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies of the prior art and provide a magnetic force controlled automatic release device for meteorological balloons.

[0005] To achieve the above purpose, a magnetic force controlled automatic release device for meteorological balloons is designed, which is characterized by including a vertically arranged reversing support rod with an upper opening and a through hole on one side; a horizontally arranged automatic release device, the automatic release device including a rocker arm and an electromagnet, the opening end of the automatic release device being arranged on the side away from the reversing support rod, a magnetic absorber being provided in the middle of the rocker arm to cooperate with the electromagnet, and an extension section being provided on the rocker arm towards the opening side; a balloon tying rope, one end of the balloon tying rope being formed into a loop and connected to the extension section of the rocker arm, the balloon tying rope passing through the side wall through hole and the upper opening of the reversing support rod, and the other end being connected to the meteorological balloon.

[0006] The positions of the electromagnet and the magnetic absorber can be interchanged with each other.

[0007] The device further includes a base, the reversing support rod and the automatic release device being installed on the base, and the extension section of the rocker arm not contacting the base.

[0008] The base is also provided with a damper, which cooperates with the rocker arm.

[0009] Compared with the prior art, the advantages of the present invention are as follows:

[0010] 1. The equipment is powered by 12V DC, ensuring the safety of personnel operation.

[0011] 2. The rocker arm is controlled by magnetic force, eliminating mechanical contact and making the release of the rocker arm faster and more efficient.

[0012] 3. The direction of the balloon string hanging on the rocker arm always maintains an upward oblique pull of about 45 degrees. In cooperation with the reversing bracket, the balloon can be released even in strong winds, and the influence of the wind on the automatic balloon release device can be minimized by the reversing bracket.

[0013] 4. The hydraulic damper design is adopted to reduce the impact on the electromagnetic lock when the rocker arm falls, extending the service life of the equipment.

[0014] 5. The control circuit is designed with a 5-second delay to ensure that after each button press, the electromagnet is powered on with a delay, and the armature will not be affected by the strong suction force of the electromagnet during the reset process after the balloon is released, thus avoiding the impact of the armature on the electromagnet.

[0015] 6. There is no need for a special person to manually release the balloon, enabling the meteorological sounding operation to be independently completed by one person and reducing labor costs.

[0016] 7. The operation is simple, and the person hanging the balloon can complete the balloon tying operation with one hand. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below with reference to the accompanying drawings. The structure and principle of the present invention are very clear to those skilled in the art. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] See Figure 1, the present invention provides a magnetic control meteorological balloon automatic release device. The bottom is a base, on which a reversing support rod is vertically installed. The top of the reversing support rod is open, and through holes are opened on the side of the reversing support rod. A horizontally arranged automatic release device is also installed on the base. The automatic release device includes a rocker arm and an electromagnet. The open end of the automatic release device is arranged on the side away from the reversing support rod. A magnetic absorber is provided in the middle of the rocker arm to cooperate with the electromagnet, and an extension section is provided on the rocker arm towards the open side. The meteorological balloon is tied by a balloon string. One end of the balloon string is annular and is sleeved on the rocker arm. A damper is also installed on the base to reduce the impact of the rocker arm falling on the electromagnetic lock and extend the service life of the equipment.

[0022] The working principle is as follows: When in use, the electromagnet and the magnetic absorber are separated, the rocker arm rises around the hinge, the balloon string becomes slack, and the balloon rises.
