Description

Technical Field

[0001] The present application relates to the technical field of rocket launcher ignition devices, and in particular to a novel rolling igniter for a hail-proof and rain-enhancing rocket launcher. Background Art

[0002] In the artificial weather modification operation, the 82-round rocket launch is an important technical means, which is widely used in the fields of hail prevention and rain enhancement. With the frequent occurrence of meteorological disasters and the development of social economy, the demand for artificial weather modification is growing. The existing 82-round rocket launcher mainly relies on the waist ignition method to achieve ignition and launch. This ignition method has the advantages of simple operation and low cost, and has been widely promoted and used in practical applications.

[0003] At present, the waist ignition structure of the 82-round rocket launcher commonly used in the market mostly adopts the ejector form, and the ejector acts as an ignition electrode. Specifically, ejectors are installed on both sides of the rail of the 82-round rocket launcher, and the two ejectors are respectively connected to the positive and negative poles of the power supply. After the 82-round missile is loaded, the two ejectors are respectively pressed against the copper pads at the positive and negative poles of the 82-round missile to form a complete circuit. When the 82-round missile is launched, the power supply is energized, and the two ejectors discharge at the positive and negative poles of the 82-round copper sheet, and the 82-round missile can complete the ignition and launch.

[0004] However, in order to ensure reliable electrical connection between the ejector and the positive and negative copper pads of the 82 bullet, the ejector of the existing ejector-type igniter is usually installed perpendicular to the firing direction, which makes the ejector move perpendicular to the firing direction during the firing of the 82 bullet. Since the 82 bullet moves at a high speed, the ejector vibration frequency is relatively high. For this kind of hole-axis matching movement, there is a risk of deformation of the moving axis under stress, which affects the service life of the igniter, shortens the replacement cycle of the igniter, and increases the cost of use. In addition, it is easy to fail to complete the ignition and firing of the 82 bullet normally due to untimely maintenance of the igniter. Summary of the invention

[0005] In view of the problems existing in the prior art, the present application provides a new rolling igniter for a hail-proof and rain-enhancing rocket launcher.

[0012] Optionally, the two insulating movable plates are also commonly connected with a clamping screw, and the clamping screw is located on the side of the mounting base away from the electric shock connection screw. The limiting sleeve is also sleeved on the clamping screw and located between the two insulating movable plates. The total thickness of the limiting sleeves of the electric shock connection screw, as well as the wiring terminal and the conductive bearing is equal to the thickness of the limiting sleeve on the clamping screw.

DETAILED DESCRIPTION

[0020] The following will be combined with the attached Figure 1 -Attached Figure 2 , the technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0021] The inventor of this application found that the existing 82-round rocket launcher mainly relies on the waist ignition method to achieve ignition and launch, and the traditional ejector-type igniter, during the 82-round launch movement, due to the fast movement speed of the 82-round rocket, causes the ejector to vibrate at a high frequency. For this kind of hole-axis matching movement, there is a risk of deformation of the movement axis under stress, which affects the service life of the igniter, resulting in a short replacement cycle of the igniter, high cost of use, and the failure to normally complete the ignition and launch of the 82-round rocket due to untimely maintenance of the igniter. To this end, this application discloses a new type of rolling igniter for hail-proof and rain-enhancing rocket launchers, which mainly adopts the following scheme: The embodiment of the present application discloses a new type of rolling igniter for a hail-proof and rain-enhancing rocket launcher. Figure 1 , including a mounting seat 1, and an insulating movable sheet 2 rotatably arranged on the mounting seat 1, wherein two insulating movable sheets 2 are provided, and the two insulating movable sheets 2 are symmetrically arranged on both sides of the mounting seat 1. An electric shock connection screw 21 is fixedly provided on the two insulating movable sheets 2, and a wiring terminal 3 and a conductive bearing 4 are sleeved on the electric shock connection screw 21 and located between the two insulating movable sheets 2, and an elastic member 5 for driving the insulating movable sheet 2 to deflect is provided on the mounting seat 1. In this way, by setting the conductive bearing 4 to be rollingly connected with the surface of the 82 bullet, in conjunction with the setting of the insulating movable sheet 2 and the elastic member 5, the conductive bearing 4 can keep pressing the uneven surface of the 82 bullet, thereby ensuring the working reliability of the rolling igniter; at the same time, it avoids the mechanical damage of the rolling igniter caused by high-frequency vibration during the firing process of the 82 bullet, thereby extending the service life of the igniter and reducing the maintenance cost.

[0022] Reference Figure 1As the basic structure of the entire igniter, the mounting base 1 needs to have sufficient strength and stability. The mounting base 1 can be made of cast iron or aluminum alloy. Cast iron has high strength and hardness and is suitable as a basic structural material; aluminum alloy is light and easy to process, and is suitable for occasions with strict weight requirements.

[0023] Reference Figure 1 The insulating movable sheet 2 is one of the core components of the entire igniter, responsible for isolating the current and supporting the conductive bearing 4.

The total thickness of each limiting sleeve 23 of the electric contact connection screw 21, the wiring terminal 3 and the conductive bearing 4 is equal to the thickness of the limiting sleeve 23 on the clamping screw 24. This increases the connection firmness of the two insulating movable plates and ensures that the two insulating movable plates are parallel and have the same spacing.

During the process of pushing the 82 projectiles, the conductive bearings 4 on the two rolling igniters are rollingly connected to the outer surface of the 82 projectiles. At the same time, the insulating movable sheets 2 on the two rolling igniters are adaptively rotated on the mounting seat 1 under the elastic force of the tension spring to ensure that the conductive bearings 4 always press against the outer surface of the 82 projectiles. After the 82 projectiles are pushed into the specified position, the conductive bearings 4 on the two rolling igniters respectively press the positive and negative copper pads of the 82 projectiles. At this time, the wiring terminals 3 on the two rolling igniters respectively form a complete circuit through the conductive bearings 4 and the positive and negative on the 82 projectiles, and the ignition of the 82 projectiles can be realized. The rolling igniter of the present application is connected to the surface of the 82 bullet by setting a conductive bearing 4 in a rolling manner, and cooperates with the setting of the insulating movable sheet 2 and the tension spring, so that the conductive bearing 4 can keep pressing the uneven surface of the 82 bullet, thereby ensuring the working reliability of the rolling igniter; at the same time, it avoids mechanical damage to the rolling igniter caused by high-frequency vibration during the firing process of the 82 bullet, thereby extending the service life of the igniter and reducing maintenance costs.
