Description

Technical Field

[0001] The invention relates to the technical field of throwing training, in particular to a portable combined throwing training device and a use method thereof. Background Art

[0002] Hand grenades are light ammunition thrown by hand. They are powerful weapons for close combat of individual soldiers. They are also small hand-thrown ammunition that can attack and defend. They can be used to kill and wound the enemy, destroy the enemy's manpower, and confuse the enemy to implement cover operations. If necessary, several hand grenades can be tied together to destroy enemy weapons and equipment, tanks, armor, vehicles, fortifications, obstacles, buildings, etc. Hand grenades are small in size, light in weight, powerful, simple in structure, reliable in performance, and easy to use. They can explode even when thrown in rain, snow, mud, or even water, and have played an important role in all previous wars. Generally, they are composed of two parts: the projectile body and the fuse (or ignition piece). The shape of the projectile body is usually cylindrical, oval, barrel-shaped, etc. Some also have a handle, and the projectile body is filled with explosives or other fillings. Generally, delayed ignition parts, percussion (pull) delay fuses, trigger fuses or delay / trigger dual-purpose fuses are used. According to their use, they can be divided into main grenades, special grenades and auxiliary grenades. Main grenades can be divided into offensive grenades, defensive grenades, dual-purpose offensive and defensive grenades and armor-piercing grenades.

[0003] During the grenade throwing training, the partition walls are arranged on the training ground according to a certain training method, and the trainees complete the five grenade throwing methods of swinging, rolling, plugging, tossing and throwing on the training ground. Nowadays, the partition walls used for the layout of grenade training grounds have a single structure, are not easy to fix on the ground, and the layout takes a long time. At the same time, simulated grenades are used in training.

During the throwing process, the first position sensor senses the positional relationship between the second position sensor, the third position sensor, the fourth position sensor, and the first and fifth position sensors respectively. , and transmit the signal to the single-chip computer, which is used to sense the running trajectory of the grenade. When the simulated grenade falls to the ground, it generates vibration. The vibration sensor transmits the signal to the single-chip computer. The single-chip computer controls the stereo effect to emit the explosion sound of the real grenade stored in advance. The sound of gunfire is played continuously by the stereo sound. Then run to the throwing point of the partition wall one, and throw the grenade to the explosion effective area A on the side of the partition wall. Then run to the throwing point of the partition wall two, and throw the grenade to the explosion effective area A on the side of the partition wall two. Then aim at the throwing point of the partition wall three. Throw the grenade through the slot, then throw the grenade above the fourth partition wall at the fourth position of the partition wall, then run to the throwing point at the fifth partition wall and throw the grenade at the target platform. The area between the inner and outer rings is the effective throwing area. The grenade is effective if it is thrown within the effective area. After the grenade on the target platform explodes, the infrared laser automatic timer ends the timing, and the instructor records the time on the timer and resets it. The instructor gives a comprehensive score based on the trainee's grenade landing position, throwing posture, and training time, and then waits for the next trainee to repeat the above training steps.

A portable combined throwing training equipment according to claims 1-7, characterized in that: Here’s how to use it: S1: First, help the officers and soldiers to become familiar with the actual grenade throwing process, and provide psychological counseling for those with poor psychological quality, strengthen the standardized risk avoidance training of live ammunition throwing personnel, set up single-chip microcomputers around, and use MCS51 single-chip microcomputer model, then move the partition wall 1 (1), partition wall 2 (2), partition wall 3 (3), partition wall 4 (4), and partition wall 5 (5) to the designated location, rotate the ground nails (11) at the bottom to make the ground nails (11) vertical, and then arrange the partition wall 1 (1), partition wall 2 (2), partition wall 3 (3), partition wall 4 (4), and partition wall 5 (5) in parallel front and back and fix them to the ground through the ground nails (11), so that the partition wall 1 (1), partition wall 2 (2), partition wall 3 (3), partition wall 4 (4) and partition wall 5 (5) are separated by ten meters; S2: a starting point (6) is set on the side of the partition wall (1) away from the partition wall (2), a target platform (7) is set at a distance of 25 meters from the partition wall (5) away from the partition wall (4), and an infrared laser automatic timer is set at the starting point (6) and the partition wall (5) to automatically record the training time; S3: Draw two concentric sector areas with an angle of 45° on the sides of partition wall 1 (1) and partition wall 2 (2), with an inner diameter of 3M and an outer diameter of 6M. The area between the inner and outer circles is the effective explosion area (A); S4: Cameras are placed at fixed points on the positions of partition wall 1 (1), partition wall 2 (2), partition wall 3 (3), partition wall 4 (4), and partition wall 5 (5) to capture the grenade throwing posture of the trainees and the location of the grenade landing; S5: Place stereo speakers, high-pressure fans and smoke generators at the throwing points of partition wall 1 (1), partition wall 2 (2), partition wall 3 (3), partition wall 4 (4) and partition wall 5 (5). The smoke generator uses the S-595-London-Fogger Super Power Fire Smoke Generator. The stereo speakers play the pre-stored explosion and gunshot sounds of real grenades in real time. The wind direction of the high-pressure fan blows toward the throwing point. The smoke generator is placed at the back of the high-pressure fan. The smoke floats with the wind of the high-pressure fan and blows toward the personnel in training. Tactical backgrounds are interspersed in the organization of actual throwing to create a real combat atmosphere and effectively shorten the "scissors gap" between training and combat. S6: The trainee puts on the training equipment and starts timing at the starting point (6). The hand grenade is a simulated hand grenade. A first position sensor and a vibration sensor are installed in the simulated hand grenade. The vibration sensor adopts a QI-4G wireless vibration sensor. A second position sensor is arranged in the effective explosion area (A). A third position sensor is installed on the partition wall three (3). A fourth position sensor is installed on the partition wall four (4). A fifth position sensor is arranged in the effective throwing area of ​​the target platform (7). The first position sensor, the second position sensor, the third position sensor, the fourth position sensor, and the first and fifth position sensors all adopt NJK-5002C Hall sensors. The first position sensor, the second position sensor, the third position sensor, the fourth position sensor, the first and fifth position sensors, the infrared laser automatic timer, the stereo, the high-pressure fan, the vibration sensor and the smoke generator are all electrically connected to the single-chip computer and connected to an external power supply. During the throwing process, the first position sensor senses the positional relationship between the second position sensor, the third position sensor, the fourth position sensor, and the first and fifth position sensors, and transmits the signal to the single-chip computer. The machine is used to sense the running trajectory of the grenade. When the simulated grenade falls to the ground, it generates vibration. The vibration sensor transmits the signal to the single-chip microcomputer. The single-chip microcomputer controls the stereo sound to emit the explosion sound of the real grenade stored in advance. The gunshot sound is played continuously by the stereo sound. Then, the user runs to the throwing point of the partition wall 1 (1) and throws the grenade to the explosion effective area (A) on the side of the partition wall 1 (1). Then, the user runs to the throwing point of the partition wall 2 (2) and throws the grenade to the explosion effective area (A) on the side of the partition wall 2 (2). Then, the user aims the throwing point of the partition wall 3 (3) at the through slot (12 ) throws a grenade, then throws a grenade above the fourth (4) wall at the fourth (4) position of the partition wall, then runs to the throwing point at the fifth (5) wall and throws a grenade at the target platform (7). The area between the inner and outer rings is the effective throwing area. The grenade thrown in the effective area is effective. After the grenade hits the target platform (7), the infrared laser automatic timer ends the timing. The instructor records the time on the timer and resets it to zero. The instructor gives a comprehensive score based on the grenade landing position, throwing posture, and training time of the trainee, and then waits for the next trainee to repeat the above training steps.

9. The method for using the portable combined throwing training equipment according to claim 7, characterized in that: In S1, partition wall one (1) and partition wall two (2) are arranged in parallel front to back, partition wall three (3) and partition wall four (4) are arranged left to right, and partition wall five (5) is arranged front to back.

10. The method for using the portable combined throwing training equipment according to claim 7, characterized in that: In said S3, the two said effective explosion zones (A) are respectively drawn between partition wall 1 (1) and partition wall 2 (2), and between partition wall 2 (2) and partition wall 3 (3).
