Description
Technical Field
[0001] The utility model relates to the technical field of ignition contacts, in particular to an improved ignition contact for a rocket launcher for rain enhancement and hail prevention. Background Art
[0002] The ignition contact in the rocket launch track for rain enhancement and hail prevention is a key component of the rocket launch device for rain enhancement and hail prevention. It is located at an appropriate position in the launch track, and its main function is to transmit the ignition electrical energy emitted by the rocket launch controller to the rocket projectile. When the conductive copper sheet on the rocket projectile contacts the ignition contact, the ignition voltage is transmitted to the rocket projectile, igniting the rocket engine to work.
[0003] However, the current ignition contacts have the following deficiencies: The ignition contact can only achieve telescopic movement in the vertical direction by using a spring, and is in rigid contact with the rocket projectile in the horizontal direction, which is easily damaged due to high-speed friction. At the same time, the ignition contact is easily adhered to the residue of the rocket projectile tail flame, resulting in poor contact.
[0004] Therefore, it is necessary to design an improved ignition contact for a rocket launcher for rain enhancement and hail prevention that can avoid rigid contact with the rocket projectile in the horizontal direction and automatically remove the residue. Content of the Utility Model
[0005] In order to overcome the deficiencies that the ignition contact can only achieve telescopic movement in the vertical direction by using a spring, and is in rigid contact with the rocket projectile in the horizontal direction, which is easily damaged due to high-speed friction. At the same time, the ignition contact is easily adhered to the residue of the rocket projectile tail flame, resulting in poor contact, the technical problem is: to provide an improved ignition contact for a rocket launcher for rain enhancement and hail prevention that can avoid rigid contact with the rocket projectile in the horizontal direction and automatically remove the residue.
[0006] The technical solution of the utility model is: an improved ignition contact for a rocket launcher for rain enhancement and hail prevention, which includes a clamping frame, a first ball, a second ball and a scraping frame. The lower part of the clamping frame is movably clamped with the first ball. The lower part of the clamping frame is connected with the scraping frame, and the scraping frame is used to limit the first ball. A plurality of second balls are placed between the clamping frame and the first ball.
[0007] Furthermore, the lower part of the scraping frame is inclined inward to facilitate scraping the residue on the surface of the first ball and discharging it outward.
[0008] Furthermore, the inner wall of the scraping frame is arc-shaped, the inner wall of the scraping frame fits with the first ball, and the thickness of the scraping frame is the same as the diameter of the second ball.
[0009] Furthermore, it also includes a fixing block and a limiting component. The clamping frame is slidably connected with the fixing block, and the fixing block is provided with a limiting component for limiting the position of the clamping frame.
[0010] Further, guiding grooves are formed on both the left and right sides of the fixed block. The clamping frame slides within the guiding grooves on the fixed block. A notch is formed on the front side of the upper part of the fixed block, and the clamping frame can be removed by sliding out through the notch in the upper part of the fixed block.
[0011] Further, the limiting component includes a spring and a resisting plate. A spring is connected to the middle of the fixed block, and a resisting plate is connected to the lower side of the spring. The resisting plate contacts the clamping frame.
[0012] The beneficial effects are as follows: 1. During the movement of the rocket projectile of the present utility model, the first ball is driven to rotate, thus avoiding damage caused by rigid contact and friction with the rocket projectile. The second ball can make the rotation of the first ball smoother.
[0013] 2. Meanwhile, during the rotation of the first ball of the present utility model, it also contacts the scraping frame, so that the scraping frame can scrape off the residues of the rocket projectile tail flame, thereby realizing automatic cleaning and avoiding poor contact during the next use.
[0014] 3. When the first ball is damaged, the present utility model can also squeeze the clamping frame to move upward and then move forward, thereby facilitating the removal of the clamping frame, the first ball, the second ball and the scraping frame for replacement, thus facilitating maintenance and reducing maintenance costs.

[0018] The present utility model will be specifically introduced below in conjunction with the drawings and specific embodiments.
[0019] An improved ignition contact for a rocket launcher for rain enhancement and hail prevention, as Figure 1-2As shown in the figure, it includes a fixed block 1, a clamping frame 2, a first ball 4, a second ball 5 and a scraping frame 6. The lower part of the clamping frame 2 is movably clamped with the first ball 4. The lower part of the clamping frame 2 is connected with the scraping frame 6. The scraping frame 6 is used to limit the first ball 4. The lower part of the scraping frame 6 inclines inwards to facilitate scraping the residues on the surface of the first ball 4 and discharging them outwards. A plurality of second balls 5 are placed between the clamping frame 2 and the first ball 4. The inner wall of the scraping frame 6 is arc-shaped and fits with the first ball 4. The thickness of the scraping frame 6 is the same as the diameter of the second ball 5, and a limiting component 3. The fixed block 1 is slidably connected to the clamping frame 2. The fixed block 1 is provided with a limiting component 3 for limiting the position of the clamping frame 2. Guide grooves are opened on both the left and right sides of the fixed block 1. The clamping frame 2 slides in the guide grooves of the fixed block 1. A notch is opened on the front side of the upper part of the fixed block 1. The clamping frame 2 can slide out and be disassembled through the upper notch of the fixed block 1. The limiting component 3 includes a spring and a pressing plate. A spring is connected to the middle of the fixed block 1. The lower side of the spring is connected with the pressing plate. The pressing plate contacts the clamping frame 2.
[0020] When using this device, first install this device on two launch rails respectively. When the artificial hail suppression and rain enhancement rocket is pushed into the launch rack track, the first ball 4 and the clamping frame 2 will be pressed and retracted inwards, and the spring will be compressed. Due to the action of the spring, the first ball 4 is in close contact with the two conductive copper sheets on the artificial hail suppression and rain enhancement rocket. Press the rocket launch button, and the ignition electrical energy output by the rocket launch controller is transmitted to the copper flat washer through the wire. The copper flat washer then transmits the ignition electrical energy to the electrical ignition device in the rocket through the first ball 4, so that its propellant works. After the rocket is launched into the air, under the action of the spring, the first ball 4 and the clamping frame 2 are reset; during the movement of the rocket, it will drive the first ball 4 to rotate, thus avoiding damage caused by rigid contact and friction with the rocket. The second ball 5 can make the first ball 4 rotate more smoothly. At the same time, during the rotation of the first ball 4, it will also contact the scraping frame 6, so that the scraping frame 6 can scrape the residues of the rocket tail flame, thus realizing automatic cleaning and avoiding poor contact during the next use; when the first ball 4 is damaged, it can also squeeze the clamping frame 2 to move upwards and then move forward, which is convenient for taking out the clamping frame 2, the first ball 4, the second ball 5 and the scraping frame 6 for replacement, thus facilitating maintenance and reducing maintenance costs.
[0021] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
