Description

Technical Field

[0001] The utility model belongs to the field of control of beacon balloons, and particularly relates to a timed automatic needle - ejecting balloon self - destructing device. Background Art

[0002] When it is necessary to calibrate equipment by releasing beacon balloons at sea, a beacon capable of transmitting radio signals is fixed inside the balloon through a rubber band. The balloon is filled with helium so that it floats in the air, and the measurement and control equipment calibrates the equipment by tracking the beacon and the balloon. After the beacon balloon is released, it rises into the air under the action of air buoyancy and gradually moves away from the release position under the influence of the wind. The balloon is no longer controlled after being released, and it may fly into the airspace of other countries or fall in densely populated areas, posing potential safety hazards. Therefore, it is necessary to detonate and self - destruct the beacon balloon so that it falls into the sea to solve the above problems. However, the current beacon balloons do not have an automatic detonation function, and the current balloon detonation devices have problems such as complex structures and complex disassembly and assembly.

[0032] In addition, the technical solutions between various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0033] As shown in the attached Figure 1 - attached Figure 6 As shown, the present utility model provides a timed automatic needle - ejecting balloon self - exploding device, which includes a beacon balloon, a beacon ball arranged inside the beacon balloon, and a needle - ejecting device 1 arranged inside the beacon ball. The beacon ball is equipped with a beacon device capable of emitting radio signals, and the beacon balloon is a carrier for carrying the beacon ball to float in the air. The beacon balloon is filled with helium and can rise into the air and float in the air. The measurement and control equipment calibrates the equipment by tracking the beacon ball. Both the beacon balloon and the beacon ball are existing equipment;

[0034] The beacon ball includes a spherical shell 2, and the spherical shell 2 is generally made of aluminum material. An emission hole 21 is arranged on the spherical shell 2;

[0035] The needle - ejecting device 1 includes a launch tube 11 with one end sealed 111 and the other end having an opening 112, and a spring 12, a needle - ejecting push slider 13, and a needle 14 arranged in the launch tube 11 in sequence along the direction from the sealed end 111 to the opening 112;

[0036] The opening 112 is in communication with the emission hole 21. The needle - ejecting device 1 further includes a control device 15 for locking or unlocking the position of the needle - ejecting push slider 13. When the control device 15 locks the needle - ejecting push slider 13, the needle - ejecting push slider 13 is in a state of compressing the spring 12. When the control device 15 unlocks the needle - ejecting push slider 13, the needle - ejecting push slider 13 is released from the restriction, and the spring 12 will push the needle - ejecting push slider 13 to move quickly. Then, the needle - ejecting push slider 13 pushes the needle 14 to shoot out at high speed from the emission hole 21, and then pierces the inner side of the skin of the beacon balloon, and the beacon balloon explodes under the internal pressure.

[0037] The timing automatic needle - ejecting balloon self - destructing device provided by the utility model can control the beacon balloon to explode and self - destruct, enabling the beacon balloon to explode and fall in advance after the equipment calibration is completed, avoiding the beacon balloon floating away from the target area, further avoiding the situation of being unable to be recovered and thus affecting the environment, or avoiding the beacon balloon flying into the airspace of other countries, or avoiding potential safety hazards when the beacon balloon falls in densely populated areas, etc. Specifically, the cooperation relationship between the needle - ejecting device 1 and the beacon balloon can combine the needle - ejecting device 1 with the beacon balloon, simplifying the installation difficulty of the needle - ejecting device 1. In addition, the launch hole 21 of the beacon balloon is at a certain distance from the balloon skin of the beacon balloon, which can effectively improve the detonation effect of the beacon balloon. The needle - ejecting device 1 stores energy through the spring 12 and then realizes the launch of the ejector pin 14, having the advantages of simple and reliable structure, easy control, and high detonation success rate.

[0038] In one embodiment, the needle - ejecting device 1 further includes a needle - ejecting guide block 16 arranged on one side of the opening 112 of the launch tube 11. A guide hole 161 for the ejector pin to slide is provided on the needle - ejecting guide block 16. In this embodiment, when the ejector pin pushes the slider 13 to push the ejector pin 14, the launch directivity of the ejector pin 14 can be improved, thereby ensuring that the ejector pin 14 is launched from the launch hole 21.

[0039] In one embodiment, the size of the guide hole 161 is smaller than the size of the needle - ejecting slider 13. In this embodiment, the needle - ejecting guide block 16 can be used to limit the further movement of the needle - ejecting slider 13, that is, the needle - ejecting slider 13 can only move between the spring 12 and the needle - ejecting guide block 16.

[0040] In one embodiment, a through - hole 113 is provided on the launch tube 11, and a hole 131 is provided on the needle - ejecting slider 13;

[0041] The control device 15 includes a limiting rod 151 and a driving mechanism 152 for driving the limiting rod 151 to move. The limiting rod 151 can pass through the through - hole 113 and penetrate into the hole 131 to limit the needle - ejecting slider 13. At this time, the needle - ejecting slider 13 is limited by the limiting rod 151 and compresses the spring 12. When the driving mechanism 152 drives the limiting rod 151 to leave the hole 131, the limit on the needle - ejecting slider 13 is released. At this time, the spring 12 releases the restoring force, thereby driving the needle - ejecting slider 13 to move in the launch tube 11.

[0042] Preferably, two through - holes 113 are coaxially arranged on the opposite wall surfaces of the launch tube 11, and the hole 131 on the needle - ejecting slider 13 is also a through - hole. At this time, the limiting rod 151 first passes through one through - hole 113, then completely passes through the hole 131, and finally passes out from the other through - hole 113, thereby improving the limiting stability of the needle - ejecting slider 13 and at the same time facilitating the assembly personnel to observe whether the limiting is stable.

[0043] In one embodiment, the driving mechanism 152 is a servo motor fixedly arranged on the outer wall of the launching tube 11; the limiting rod 151 is made of a deformable material, such as deformable metal materials like copper wire or iron wire. At this time, one end of the limiting rod 151 is fixedly connected to the swing arm of the servo motor, and the other end passes through the through hole 113 and the hole 131. When the swing arm of the servo motor rotates, the limiting rod 151 can be disengaged from the through hole 113 and the hole 131, thereby releasing the restriction. In this embodiment, the structures of the driving mechanism 152 and the limiting rod 151 are simple and reliable in use.

[0044] In one embodiment, a film 17 is provided on the opening 112 of the launching tube 11. The film 17 can prevent the firing pin 14 from slipping out from the opening 112 and the launching hole 21 when the firing pin pushes the slider 13 to be in the position locking state. When the firing pin pushes the slider 13 to unlock the position, the firing pin 14 can pierce the film 17 for launching.

[0045] In one embodiment, the control device 15 further includes a power supply 153, a relay 154, and a timer 155;

[0046] The power supply 153, the relay 154, and the driving mechanism 152 are connected in series in sequence to form a circuit;

[0047] The power supply 153, the relay 154, and the timer 155 are connected in series in sequence to form a circuit.

[0048] The connection relationships of the power supply 153, the relay 154, the timer 155, and the driving mechanism 152 are as shown in the appendix Figure 6 As shown, during the timing process of the timer 155, the relay 154 is in the attracted state, the output part between A and B of the relay 154 is conducting, and the part between B and C is in the off state. No current passes through the driving mechanism 152 and it is in the initial state. When the set time is reached, the timing control outputs a signal to cut off the power supply of the relay 154. The relay 154 disconnects, the part between B and C is in the conducting state, the driving mechanism 152 is powered on, and the swing arm rotates. The swing arm drives the limiting rod 151 to leave the hole 131 and the through hole 113, releasing the restriction on the firing pin pushing the slider 13. The spring 12 pushes the firing pin pushing the slider 13 to move inside the launching tube 11, and drives the firing pin 14 to pierce the film 17 and launch from the launching hole 21. The firing pin 14 finally breaks through the skin of the new beacon balloon (breaking through from the inside of the beacon balloon), a crack appears on the skin, and the beacon balloon 4 explodes under the internal gas pressure.

[0049] In one of the embodiments, the main body of the launch tube 11 is a cylindrical tube structure. At this time, the ejector pin pushes the slider 13, which is a cylindrical structure slidably arranged in the circular hole of the launch tube 11. A rectangular platform 114 is provided on the outer wall of the middle of the launch tube 11, and the servo motor is fixedly arranged on the rectangular platform 114. In this embodiment, it can greatly facilitate the fixation of the servo motor and improve the installation stability of the servo motor. In a specific embodiment, mounting holes are provided on the rectangular platform 114, and the launch tube 11 is fitted onto the mounting holes. At this time, the limiting rod 151 completes the relative position fixation of the launch tube 11 and the rectangular platform 114, thereby simplifying the fixation of the rectangular platform 114 and the launch tube 11.

[0050] In one of the embodiments, the spherical shell 2 is formed by detachably connecting two hemispheres, which facilitates the installation of the beacon and the ejector pin device 1.

[0051] In one of the embodiments, the beacon ball is arranged in the middle of the interior of the beacon balloon. At this time, the gravity balance of the beacon balloon can be ensured, and it can be ensured that the ejector pin 14 can fly a certain distance after being launched from the launch hole 21 and then break through the skin of the beacon balloon.

[0052] The above is only this embodiment and does not impose any limitations on the present invention. Any person skilled in the art can make many possible changes, modifications or equivalents to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
