Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting robots, in particular to a hidden ejection fire-fighting robot. Background Art

[0002] The fire-fighting robot mainly uses a single-chip microcomputer as the control core, assisted by infrared flame sensors, motor drives, infrared sensor circuits, and ground grayscale sensor circuits. The vehicle is started through a control device, and the fire-fighting bombs are launched through an electromagnetic catapult.

[0003] A type of hidden ejection fire-fighting robot currently in use has an electromagnetic ejection tube in which the electromagnetic ejection tube is mostly not concealed, so that the electromagnetic ejection tube is exposed to the outside for a long time, causing it to easily come into contact with external forces and be damaged, which is not conducive to subsequent fire-fighting operations and reduces the service life of the fire-fighting robot. At the same time, the fire-fighting robot does not have the function of electrically adjusting the electromagnetic ejection tube horizontally. Therefore, when adjusting, the staff needs to perform manual operation, which is time-consuming and labor-intensive, thereby affecting the fire-fighting progress of the fire-fighting robot and is not conducive to subsequent use.

[0004] In summary, the present invention solves the problems in the above-mentioned background technology by designing a hidden ejection fire-fighting robot. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] For examples, see Figure 1-4, the utility model provides a technical solution:

[0027] A concealed ejection fire-fighting robot comprises a mounting base 1 and a barrel 2 mounted on top of the mounting base 1. A crawler base 3 is fixedly mounted on the bottom of the mounting base 1. A ball bearing 4 is disposed on the top of the mounting base 1. A mounting cavity 5 is defined within the mounting base 1. A support shaft 501 and a drive motor 502 are disposed within the mounting cavity 5. A slave gear 5011 is sleeved on the outer side of the support shaft 501. A master gear 5021 is disposed on the output end of the drive motor 502. An electromagnetic ejection cylinder 6 is disposed within the barrel 2. A concealed mechanism 7 is disposed between the electromagnetic ejection cylinder 6 and the barrel 2.

[0028] Specifically, the balls 4 are embedded in the top surface of the mounting seat 1 and are equidistantly distributed in a circular pattern about the top central axis of the mounting seat 1. The outer top surfaces of the balls 4 are in rolling contact with the bottom surface of the cylinder 2. The support shaft 501 is rotatably connected to the inner wall of the mounting cavity 5 via a rotating member, and its top end fits through the top inner wall of the mounting cavity 5 and is fixed to the bottom center surface of the cylinder 2. The main gear 5021 is meshed with the slave gear 5011.

[0029] In this embodiment, the driving motor 502 is mainly used to drive the meshing transmission between the main gear 5021 and the slave gear 5011, thereby realizing the rotation of the support shaft 501, and the ball 4 is mainly used to form rolling contact with the bottom surface of the cylinder 2, thereby achieving the effect of horizontal rotation of the cylinder 2, meeting the adjustment needs of the staff.

[0030] In this embodiment, please refer to Figure 1 、 Figure 3 and Figure 4 , the hidden mechanism 7 includes a fastening seat 701, a square groove 702 and a baffle 703. The fastening seat 701 is fixedly mounted on the bottom end of the inner part of the cylinder 2, and a servo motor 704 is fixedly arranged on the right side thereof. The output end of the servo motor 704 is fixedly sleeved with a number one gear 705. A support bracket 706 is provided on the inner side of the fastening seat 701 for rotation through a pin shaft. A number two gear 707 is fixedly installed inside the support bracket 706 through a fixed shaft. The square groove 702 and the baffle 703 are both arranged on the outer surface of the cylinder 2;

[0031] Specifically, the vertical cross-section of the fastening base 701 is U-shaped. The output end of the servo motor 704 movably penetrates the right side surface of the fastening base 701 and extends to the inner side thereof. The first gear 705 and the second gear 707 are meshed and connected. The front inner wall of the square groove 702 extends to the interior of the cylinder 2, and the outer inner wall size thereof is larger than the outer size of the electromagnetic catapult tube 6. One side of the baffle 703 fits and penetrates the outer surface of the cylinder 2, and its outer surface covers and fits with the inner wall of the square groove 702.

[0032] In this embodiment, the servo motor 704 is mainly used to drive the No. 1 gear 705. Under the transmission cooperation of the No. 1 gear 705 and the No. 2 gear 707, the support bracket 706 drives the electromagnetic catapult tube 6 to rotate vertically, so that the electromagnetic catapult tube 6 is vertically placed inside the cylinder body 2, and the baffle 703 is mainly used to cover the square groove 702, thereby achieving the purpose of hiding and storing the electromagnetic catapult tube 6, meeting the protection requirements of the electromagnetic catapult tube 6.

[0033] The working process of the present utility model is as follows: when a hidden ejection fire extinguishing robot is used, the fire extinguishing robot is first moved to the desired position through the crawler base 3, and then the inclination angle of the electromagnetic ejection tube 6 is adjusted according to the actual situation, and the servo motor 704 is started. The output end of the servo motor 704 drives the No. 1 gear 705 to rotate, and the No. 1 gear 705 drives the No. 2 gear 707 to rotate, and the No. 2 gear 707 drives the support bracket 706 and the fastening seat 701 to rotate, thereby completing the inclination angle adjustment of the electromagnetic ejection tube 6, and then the drive motor 502 is started. The output end of the drive motor 502 drives the main gear 5021 to engage with the slave gear 5011 for transmission, and the slave gear 5011 drives the support shaft 501 and the cylinder body 2 to rotate. At this time, the bottom of the cylinder 2 forms a rolling contact with the outer top surface of the ball 4, thereby realizing the horizontal rotation of the electromagnetic catapult tube 6 and meeting the adjustment needs of the staff. Finally, the fire extinguishing bomb is put into the electromagnetic catapult tube 6. Under the action of the electromagnetic catapult tube 6, the fire extinguishing bomb is ejected toward the fire source, thereby completing the fire extinguishing operation. Further, when it is necessary to hide the electromagnetic catapult tube 6, the servo motor 704 drives the No. 1 gear 705 and the No. 2 gear 707, so that the support bracket 706 drives the electromagnetic catapult tube 6 to gradually become vertical and enter the interior of the cylinder 2, and then pushes the baffle 703 so that the baffle 703 covers the square groove 702, thereby completing the hiding operation of the electromagnetic catapult tube 6, which is convenient for its protection and subsequent use.

[0034] 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
