Description

Technical Field

[0001] This utility model relates to the field of throwing device technology, specifically to a fire extinguishing bomb and its throwing device. Background Technology

[0002] Forest fire extinguishing grenades are suitable for extinguishing large-scale fires in mountains, forests, grasslands, etc., and are one of the cutting-edge weapons for large-scale forest fire extinguishing. Hand-held throwable fire extinguishing grenades are the most common type of forest fire extinguishing grenades, but the throwing efficiency of hand-held throwable fire extinguishing grenades is relatively low.

[0003] To improve the throwing efficiency of forest fire extinguishing bombs, a utility model patent with publication number CN218106615U discloses a bomb-throwing frame for forest fire extinguishing bombs. This frame incorporates a catapult mechanism and a loading tube. When throwing fire extinguishing bombs using this device, the push block in the catapult mechanism is first pulled backward to the innermost end of the loading tube. Multiple fire extinguishing bombs are then placed inside the loading tube, and the device can be aimed at the target and launched. While this design facilitates automatic launching of fire extinguishing bombs, it has limited adjustment of the throwing angle. When throwing at distant targets, it is not convenient to adjust the throwing height and angle of the fire extinguishing bombs appropriately, resulting in significant limitations in the throwing process.

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Please see Figures 1 to 4 A fire extinguishing grenade and a throwing device are disclosed. The throwing device includes a base plate 1, a connecting frame 2, a mounting frame 3, a throwing tube 4, a throwing plate 5, and an elastic spring 6. A movable component is provided at the bottom end of the base plate 1. The connecting frame 2 is lifted and installed on the upper side of the base plate 1 via a lifting component. The mounting frame 3 is rotatably installed on the upper side of the connecting frame 2 via a drive seat. The throwing tube 4 is fixedly connected to the top end of the mounting frame 3. The throwing plate 5 is slidably connected to the throwing tube 4 via a throwing component. The throwing plate 5 has a throwing groove that matches the fire extinguishing grenade 23, which can increase the stability of the contact between the fire extinguishing grenade 23 and the throwing plate 5. The elastic spring 6 is fixedly connected between the throwing plate 5 and the inner side wall of the throwing tube 4. Two limiting blocks 21 are symmetrically connected on the throwing plate 5. The throwing tube 4 has a limiting groove for the limiting blocks 21 to slide, which facilitates the limiting of the sliding of the throwing plate 5 in the throwing tube 4.

[0049] Please see Figures 1 to 4The throwing assembly includes a protective cylinder 7, a first electric cylinder 8, a pulling plate 9, and a sliding plate 10. The protective cylinder 7 is fixedly connected to the top of the throwing cylinder 4. The first electric cylinder 8 is installed on the inner side wall of the protective cylinder 7. The pulling plate 9 is fixedly connected between the output end of the first electric cylinder 8 and the throwing plate 5. The throwing cylinder 4 has a through-hole for the pulling plate 9 to move. The sliding plate 10 is fixedly connected to the top of the pulling plate 9. The inner top wall of the protective cylinder 7 has a sliding groove for the sliding plate 10 to slide, which facilitates increasing the stability of the sliding plate 10 sliding inside the protective cylinder 7.

[0050] By pulling the first electric cylinder 8 to pull the pull plate 9, the throwing plate 5 can be moved inside the throwing tube 4 by the elastic force of the elastic spring 6, so as to throw the fire extinguishing bomb 23.

[0051] Please see Figures 1 to 4 The moving assembly includes a base rod 11, a self-locking wheel 12, a pedal 13, and a fixed cone 14. Multiple base rods 11 are provided, and all base rods 11 are fixedly connected to the bottom end of the base plate 1. The self-locking wheel 12 is installed at the bottom end of each base rod 11. The pedal 13 is slidably connected to each base rod 11. The friction between the pedal 13 and the base rod 11 is large, so the pedal 13 will not move arbitrarily on the base rod 11. The fixed cone 14 is fixedly connected to the bottom end of each pedal 13.

[0052] The base plate 1 is easily moved by the cooperation of multiple base rods 11 and multiple self-locking wheels 12. When it is necessary to fix the base plate 1, the self-locking wheels 12 are locked and force is applied to the pedal 13, so that the pedal 13 drives the fixed cone 14 to move, so that the fixed cone 14 can be embedded into the ground, thereby increasing the stability of the placement of the base plate 1, connecting frame 2, mounting frame 3 and throwing tube 4.

[0053] Please see Figures 1 to 4 The lifting assembly includes a second electric cylinder 15, a lifting plate 16, a support cylinder 17, a support rod 18, and a locking rod 19. There are two second electric cylinders 15, which are symmetrically installed on the top of the base plate 1. The lifting plate 16 is fixedly connected to the output end of each second electric cylinder 15, and both lifting plates 16 are fixedly connected to the connecting frame 2. There are two support cylinders 17, which are symmetrically connected to the base plate 1. The support rod 18 is slidably connected to each support cylinder 17, and the support rod 18 is fixedly connected to the connecting frame 2. The locking rod 19 is connected to each support rod 18. The support cylinder 17 has a slot for the locking rod 19 to slide, which can increase the stability of the support rod 18 sliding in the support cylinder 17.

[0054] By pushing the two lifting plates 16 with the two second electric cylinders 15, the two lifting plates 16 can drive the connecting frame 2 to move. At the same time, the two support cylinders 17 and the two support rods 18 facilitate the smooth movement of the connecting frame 2.

[0055] Please see Figures 1 to 4 The drive base includes a motor 20 and a drive rod. The motor 20 is mounted on one side of the connecting frame 2 through a mounting sleeve. The drive rod is fixedly connected between the output end of the motor 20 and the mounting frame 3, and the drive rod is rotatably connected to the connecting frame 2.

[0056] The motor 20 rotates the drive rod, which in turn drives the mounting frame 3 to rotate, thereby allowing the mounting frame 3 to rotate the throwing tube 4 and thus adjust the throwing angle of the fire extinguishing bomb 23.

[0057] In summary, when the throwing height of the fire extinguishing grenade 23 needs to be adjusted, the two second electric cylinders 15 push the two lifting plates 16, causing the connecting frame 2 to move the mounting frame 3 and the throwing tube 4. When the throwing angle of the fire extinguishing grenade 23 needs to be adjusted, the motor 20 and the drive rod rotate the mounting frame 3, causing the mounting frame 3 to rotate the throwing tube 4 to the appropriate angle. Then, the first electric actuator pulls the pulling plate 9, causing the throwing plate 5 to move inside the throwing tube 4 by the elastic force of the elastic spring 6. The throwing plate 5 pushes and throws the fire extinguishing grenade 23.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
