[0002] According to the investigation, the number of fire accidents in my country has been on the rise in recent years. After a fire occurs, the fire department should conduct corresponding fire investigations, give investigation conclusions, and issue corresponding reports. The main purpose is to determine the cause of the fire, reproduce the fire process, and verify casualties and property losses. In addition, through the investigation and statistics of a large number of fire accidents, relevant laws can be found to accumulate cases and experience for future fire prevention and fire fighting. Therefore, fire investigation is necessary and of great significance. At present, the investigation after the fire usually sends a large number of investigators to survey the scene of the fire accident. In this process, on-site evidence collection is required, such as taking photos. However, the on-site environment after the fire is relatively harsh, with certain hidden dangers, and some narrow terrains are inconvenient for investigators to enter. Therefore, drones are introduced into the field of fire investigations with their small size and flexible operation. However, the existing fire investigation drones have fixed rotors, and the cameras used for taking photos are always exposed to the air, making the overall carrying inconvenience and the camera easily damaged. Moreover, the camera is always exposed to the air and is easily contaminated with soot and other debris, affecting the clarity of the photos.

[0003] To this end, we propose a portable firefighting drone for fire investigation to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] like Figure 1-5 As shown, a portable fire-fighting drone for fire investigation includes a fuselage 1, a storage box 3 is fixedly connected to the upper end of the fuselage 1, a control box 2 is fixedly installed on the upper end of the storage box 3, two storage chambers 5 are symmetrically provided in the storage box 3, the storage chamber 5 is limitedly slidably connected to a limit block 6, the opposite ends of the two limit blocks 6 are fixedly connected to a rotor arm 4, a plurality of magnetic blocks 8 are embedded in the storage box 3, magnets 7 are embedded at both left and right ends of the two limit blocks 6, and the rotor arms 4 of the storage chamber 5 are limited by the magnetic force cooperation of the magnets 7 and the magnetic blocks 8, so that it is easy to carry.

[0027] A flight motor 41 is fixedly installed on the upper end of the rotor arm 4, and a plurality of rotors 42 are rotatably connected to the output end of the flight motor 41. A horizontal plate 9 is fixedly connected to the inner side walls of the fuselage 1. Two vertical plates 10 are fixedly connected to the lower end of the horizontal plate 9 at intervals. Two slide grooves 11 are symmetrically provided at the opposite ends of the two vertical plates 10. A lifting plate 12 is slidably connected to the two slide grooves 11. A camera 16 is fixedly installed on the lower end of the lifting plate 12 through a mounting plate. A first spring 13 is fixedly connected between the lifting plate 12 and the horizontal plate 9. A first movable groove 14 connected to the slide groove 11 is provided on the vertical plate 10 on the left. The width of the first movable groove 14 is smaller than the width of the slide groove 11 to prevent the lifting plate 12 from shifting.

[0028] The left end of the lifting plate 12 is fixedly connected with a connecting rod 15, and the connecting rod 15 is arranged through the first movable groove 14. The lower wall of the fuselage 1 is provided with a sliding cavity 18 and an extension port 29 from left to right. The length of the sliding cavity 18 is h4, and the length of h4 is greater than or equal to the total length of h3 and h5, ensuring that after the baffle 17 slides into the sliding cavity 18, the sliding cavity 18 has enough length for the baffle 17 to continue sliding, and will not affect the extension of the camera 16.

[0029] The length of the extended opening 29 is h3, the sliding cavity 18 is slidably connected with a baffle 17, a second spring 19 is fixedly connected between the baffle 17 and the sliding cavity 18, a rope groove connected to the sliding cavity 18 is provided on the inner bottom wall of the fuselage 1, the left end of the baffle 17 and the lower end of the first connecting block 27 are connected with a pull rope 20 through a guide wheel, an installation box 21 is fixedly connected to the left side of the fuselage 1, two dovetail grooves 22 are provided on the inner walls of both sides of the installation box 21, the two dovetail grooves 22 are respectively limited and slidably connected with a first tooth plate 23 and a second tooth plate 24, a second movable groove 25 is provided on the installation box 21, the distance between the connecting rod 15 and the bottom end of the second movable groove 25 located on the right side is h2, and the length of h2 is greater than or equal to the length of h5, and the height of the camera 16 is h5, which ensures that the camera 16 can be fully extended for taking pictures.

[0030] The width of the second movable groove 25 is smaller than the maximum width of the dovetail groove 22 , so as to prevent the first tooth plate 23 and the second tooth plate 24 from being separated from the dovetail groove 22 .

[0031] The second movable groove 25 is connected to the dovetail groove 22, and a rotating motor is fixedly installed in the installation box 21. The output shaft of the rotating motor is fixedly connected to a gear 26 meshing with the first tooth plate 23 and the second tooth plate 24. A first connecting block 27 is fixedly connected to the lower side of the left end of the first tooth plate 23, and a second connecting block 28 is fixedly connected to the upper side of the right end of the second tooth plate 24. The distance between the second connecting block 28 and the connecting rod 15 is h1, and the length of h1 is greater than or equal to the length of h3, so as to ensure that when the second tooth plate 24 and the first connecting block 27 move upward, the baffle 17 completely enters the sliding cavity 18 before the camera 16 moves, so as to avoid obstruction of the camera 16 from extending from the baffle 17.

[0032] The first connecting block 27 and the second connecting block 28 are both disposed through the second movable groove 25 .

[0033] The working principle of the present invention is as follows:

[0034] It should be noted that the distance between the second connecting block 28 and the connecting rod 15 is h1, the length of the protruding opening 29 is h3, and the length of h1 is greater than or equal to the length of h3; the distance between the connecting rod 15 and the bottom end of the second movable groove 25 located on the right side is h2, the height of the camera 16 is h5, and the length of h2 is greater than or equal to the length of h5;

[0035] When in use, the flight motor 41 drives the rotor 42 to rotate to perform flight work. When arriving at a location where photographing is required for evidence collection, the rotating motor drives the gear 26 to rotate, driving the first tooth plate 23 and the second connecting block 28 to move downward, and the second tooth plate 24 and the first connecting block 27 to move upward. When the length of the upward movement is h1, the baffle 17 is driven by the pull rope 20 to slide to the left and completely enter the sliding cavity 18, the second spring 19 is compressed, and the second connecting block 28 contacts the connecting rod 15. When the length of the upward movement continues to be h2, the second connecting block 28 presses the connecting rod 15, driving the camera 16 to move downward through the extension port 29 to the outside of the fuselage 1 to perform photographing work;

[0036] When the photo is taken, the rotating motor drives the gear 26 to rotate in the opposite direction. Under the elastic force of the first spring 13 and the second spring 19 (the original can be easily obtained from reading and using, and will not be repeated here), the camera 16 first moves upward and retracts into the body 1, and then the baffle 17 draws the sliding cavity 18 to the right to close the extension port 29 to protect the camera.

[0037] After the work is completed, each rotor arm 4 is pushed into the storage box 3, and the magnet 7 at the opposite end of each rotor arm 4 cooperates with the magnetic block 8 located in the middle of the storage box 3 to limit the position of each rotor arm 4, thereby reducing the size of the present invention, and the camera 16 is retracted into the inside of the fuselage 1 for easy carrying.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
