Description

Technical Field

[0001] The utility model relates to the technical field of fire prevention and control, in particular to a throwing device for forest fire prevention and extinguishing bombs. Background Technique

[0002] When a fire breaks out in some places in the forest, due to the large number of trees in the forest, the traffic is inconvenient. Generally, it takes a long time for a fire truck to reach the scene. Often when it arrives at the fire site, the fire has got out of control. Moreover, the temperature near the fire site is relatively high. When firefighters are fighting the fire, if they are too close, they are easily burned, and if they are too far away, the fire fighting efficiency is relatively low. As a relatively convenient fire fighting equipment, as long as the fuse of the extinguishing bomb is opened and it is thrown into the fire field, the fire can be effectively controlled.

[0003] At present, the extinguishing bombs are mainly transported by hanging under the unmanned aerial vehicle. During the transportation process, due to the hook connection, the extinguishing bombs will shake due to the air flow resistance, and there is a problem of insufficient stability. Based on this, we propose an improvement on a throwing device for forest fire prevention and extinguishing bombs. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a throwing device for forest fire prevention and extinguishing bombs, which can effectively solve the technical problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A throwing device for forest fire prevention and extinguishing bombs includes a mounting frame, a mounting plate and an extinguishing bomb body. Guide plates are fixedly connected to the inner walls of the front and rear plates of the mounting frame near the lower end. The extinguishing bomb body is arranged on the guide plates. Side baffles are fixedly connected to the other ends of the two guide plates. A connecting plate is fixedly connected between the front and rear plates of the mounting frame. One end of the connecting plate is fixedly connected with a driving motor. The output end of the driving motor is fixedly connected with a driving shaft. A mounting roller is fixedly sleeved on the outer wall of the driving shaft. A plurality of dial plates are fixedly connected to the outer wall of the mounting roller.

[0007] As a further scheme of the utility model, the mounting plate is fixedly connected to the upper end faces of the mounting frame and the connecting plate, and a plurality of mounting holes are formed in the mounting plate.

[0008] As a further scheme of the utility model, the other end of the driving shaft is rotatably connected to the side baffle, and the plurality of dial plates are rotatably arranged between the mounting plate and the side baffle.

[0009] As a further scheme of the utility model, the minimum linear distances between the lower ends of the connecting plate and the driving motor and the guide plate are both greater than the diameter of the extinguishing bomb body.

[0010] As a further solution of the present utility model, multiple said deflector plates are evenly distributed on the outer wall of the mounting roller, and the fire extinguishing bomb body is arranged between two adjacent deflector plates.

[0011] As a further solution of the present utility model, a fixing plate is fixedly connected to the inner wall of the side plate body of the mounting frame away from the side baffle. A buffer pin and a buffer spring are respectively fixedly connected to the upper end surface of the fixing plate, and a support plate is fixedly connected to the upper ends of the buffer pin and the buffer spring.

[0012] As a further solution of the present utility model, the buffer spring is movably sleeved on the outer end of the buffer pin, and the buffer pin and the buffer spring are arranged between two front and rear guide plates.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By providing structures such as a mounting frame, guide plates, side baffles, drive shafts, mounting rollers, deflector plates, and drive motors, the drive motor can drive the drive shaft to rotate, and then the mounting roller can drive the deflector plates to rotate, so as to push the fire extinguishing bomb body out from between the side baffle and the mounting frame for throwing. After throwing one fire extinguishing bomb, the guide plates can be used to guide the movement of the second fire extinguishing bomb body to complete rapid loading. Through the combined action of the mounting frame, guide plates, side baffles, and deflector plates, the fire extinguishing bomb body can be stably transported, preventing it from being affected by air flow and causing shaking, which affects its stability.

[0015] By providing a fixing plate near the lower part between two guide plates and arranging a buffer pin and a buffer spring on the upper end of the fixing plate to support the support plate, when loading the fire extinguishing bomb into the mounting frame, mechanical buffering can be provided for the fire extinguishing bomb falling on the support plate, protecting the fire extinguishing bomb from buffering and facilitating rapid loading, which has practicality.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figures 1-4 shown, a fire extinguishing bomb delivery device for forest fire prevention includes a mounting frame 1, a mounting plate 2 and a fire extinguishing bomb body 10. Guiding plates 4 are fixedly connected to the inner walls of the front and rear plates of the mounting frame 1 near the lower end position. The fire extinguishing bomb body 10 is arranged on the guiding plates 4. The other ends of the two guiding plates 4 are fixedly connected with side baffles 5. A connecting plate 6 is fixedly connected between the front and rear plates of the mounting frame 1. One end of the connecting plate 6 is fixedly connected with a driving motor 15. The output end of the driving motor 15 is fixedly connected with a driving shaft 7. A mounting roller 8 is fixedly sleeved on the outer wall of the driving shaft 7. Multiple dial plates 9 are fixedly connected to the outer wall of the mounting roller 8.

[0023] In this embodiment, the mounting plate 2 is fixedly connected to the upper end faces of the mounting frame 1 and the connecting plate 6. Multiple mounting holes 3 are formed in the mounting plate 2. The mounting plate 2 is fixedly installed at the lower end of the unmanned aerial vehicle by sleeving bolts through the mounting holes 3, which facilitates driving the mounting frame 1 to move by the unmanned aerial vehicle. Considering that the installation of the unmanned aerial vehicle and the bomb dropping frame is a well-known technology in the art, it will not be described in detail here.

[0024] In this embodiment, the other end of the driving shaft 7 is rotatably connected to the side baffle 5. Multiple dial plates 9 are rotatably arranged between the mounting plate 2 and the side baffle 5. The horizontal height of the upper end face of the mounting plate 2 is greater than the height of the upper end face of the dial plate 9 when it rotates to the uppermost position.

[0025] In this embodiment, the minimum linear distances between the lower ends of the connecting plate 6 and the driving motor 15 and the guiding plate 4 are both greater than the diameter of the fire extinguishing bomb body 10, so as to prevent the fire extinguishing bomb body 10 from colliding with the connecting plate 6 or the driving motor 15 when moving on the guiding plate 4.

[0026] In this embodiment, multiple dial plates 9 are evenly distributed on the outer wall of the mounting roller 8. The fire extinguishing bomb body 10 is arranged between two adjacent dial plates 9. When the mounting roller 8 rotates, the fire extinguishing bomb body 10 can be driven to move out from the gap between the mounting frame 1 and the side baffle 5 by driving the dial plates 9 to rotate. And it can facilitate the next fire extinguishing bomb body 10 to move to between the two dial plates 9 under the guiding action of the guiding plate 4 after the previous fire extinguishing bomb body 10 moves out, waiting for the next delivery.

[0027] In this embodiment, a fixing plate 11 is fixedly connected to the inner wall of the side body of the mounting frame 1 away from the side baffle 5. A buffer pin 12 and a buffer spring 14 are respectively fixedly connected to the upper end surface of the fixing plate 11. The upper ends of the buffer pin 12 and the buffer spring 14 are fixedly connected to a support plate 13. The buffer pin 12 and the buffer spring 14 are used to mechanically buffer the fire extinguishing bomb body 10 that falls on the support plate 13.

[0028] In this embodiment, the buffer spring 14 is movably sleeved on the outer end of the buffer pin 12. The buffer pin 12 and the buffer spring 14 are arranged between two front and rear guide plates 4. The support plate 13 is also arranged between the two guide plates 4. And like the guide plate 4, the upper ends of the support plate 13 are all arranged as inclined downward arc surfaces.

[0029] It should be noted that the present utility model is a fire extinguishing bomb delivery device for forest fire prevention. When in use, the mounting frame 1 is loaded with bombs, and the fire extinguishing bomb body 10 will fall on the support plate 13. The buffer pin 12 cooperates with the buffer spring 14 to mechanically buffer the impact force of the fire extinguishing bomb body 10, avoiding the impact force being too large and affecting the fire extinguishing bomb body 10. As the fire extinguishing bomb bodies 10 are loaded into the mounting frame 1 one by one, under the guidance of the guide plates 4, they are arranged in a row in a straight line. Then the mounting frame 1 is fixedly installed at the lower end of the unmanned aerial vehicle by bolts passing through the mounting holes 3 on the mounting plate 2. Then the fire extinguishing bomb body 10 can be delivered to the operation area by the unmanned aerial vehicle. When the unmanned aerial vehicle delivers the bomb, the driving motor 15 is started to drive the driving shaft 7 to rotate, and then drive the mounting roller 8 to rotate, and then drive the dial 9 to laterally push the fire extinguishing bomb body 10 out from between the mounting frame 1 and the side baffle 5, completing the delivery of the fire extinguishing bomb. After one is delivered, another one enters between the two dials 9 under the guidance of the guide plate 4 and waits for the next delivery, which is convenient and time-saving.

Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
