Description

Technical Field

[0001] This utility model belongs to the field of fire extinguishing equipment, and specifically relates to a low-profile fire extinguishing robot. Background Technology

[0002] Firefighting equipment and devices are crucial tools for protecting people's lives and property. With technological advancements, firefighting equipment and devices have become increasingly sophisticated and diverse, with a wide variety of fire trucks and firefighting systems available, and large fire trucks boasting advanced equipment and powerful functions. However, fires are not limited to high-rise buildings. Low-ceilinged and confined spaces, such as under car engines, are also increasingly problematic. With the rise of new energy vehicles, car fires have also increased significantly. In such situations, the confined space, poor heat dissipation and air circulation, and the inability of people to enter, coupled with the large amounts of dust generated during operation, pose a significant danger to the lives of firefighters. Currently, there are relatively few devices and equipment available for extinguishing fires in low-ceilinged and confined spaces. Using large firefighting equipment is not only costly but also wastes resources to some extent.

[0003] Patent document CN116726433A discloses a patent application for "a fire truck for extinguishing fires in confined spaces," which includes a fire truck body, a cryogenic working fluid storage tank, a fire extinguishing working fluid storage tank, a pipeline reversing device, and a water spray nozzle. The height of the fire truck body is less than 1.9 meters. Even at 1.9 meters high, the overall size of this fire truck is still quite large, making it unsuitable for use in low-ceilinged and confined spaces. Summary of the Invention

[0004] To address the aforementioned problems, this utility model proposes a fire-fighting robot for low-ceilinged spaces, solving the problem of the lack of fire-fighting devices for low-ceilinged spaces.

[0005] This utility model is implemented as follows: a low-profile fire-fighting robot includes a walking track, a flat box-shaped body, fire-fighting nozzles, and fire hose connecting pipes. The body panel is provided with multiple nozzle outlets, and the multiple fire-fighting nozzles extend from the body panel. The body length is less than the length of the walking track. The overall height of the robot is less than 35 cm, the width is less than 50 cm, and the length is less than 100 cm.

[0006] Furthermore, eight fire extinguishing nozzles are provided, evenly and symmetrically arranged on the side of the fuselage panel near the walking track, including an inner nozzle and an outer tube, with a gap between the outer tube and the inner nozzle to form an annular water outlet.

[0007] Furthermore, the track is provided with a track guard that covers the track at the top and outside, and the length of the upper panel of the track guard is greater than the length of the track.

[0008] Furthermore, the length of the fuselage is less than the length of the upper panel.

[0009] Furthermore, one end of the fuselage is flush with one end of the track guard, and the other end forms a recessed structure with the other end of the track guard.

[0010] Furthermore, the fire hose connection pipe is installed on the body of the fire-fighting robot at the recessed end.

[0011] Furthermore, the outer side plate of the track guard is an inverted trapezoid that is wider at the top and narrower at the bottom, and the lower edge of the outer side plate is irregularly serrated.

[0012] Furthermore, the upper panel and outer side panel of the track guard are provided with reflective strips.

[0013] Furthermore, reflective strips are provided around the four sides of the fuselage panel.

[0014] Furthermore, a drag ring handle is provided at one end of the fuselage and the track guard.

[0015] The beneficial effects of this utility model are: It is compact and low-profile, allowing it to extinguish fires directly by spraying water onto objects above them via a fire-extinguishing nozzle mounted on the panel, effectively stopping the fire at its source. This utility model is particularly effective at extinguishing fires originating from very low-lying locations, such as electric cars.

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0028] A low-profile firefighting robot, such as Figures 1 to 3 As shown, it includes a walking track 1, a flat box body 2, fire extinguishing nozzles 3, a fire hose connecting pipe 4, and a body panel 21 with multiple nozzle outlets 22. The multiple fire extinguishing nozzles 3 extend from the body panel 21. The body length is less than the length of the walking track. The overall height of the robot is less than 35 cm, the width is less than 50 cm, and the length is less than 100 cm.

[0029] The fire extinguishing nozzle 3 includes an inner nozzle 31 and an outer sleeve 32. The surface of the inner nozzle 31 is similar to a shower head structure, which can spray water vertically upward. The thickness of the water jet depends on the size of the nozzle. There is a gap of a certain size between the outer sleeve 32 and the inner nozzle 31, forming an outward annular water outlet 33. The adjacent surfaces of the outer sleeve 32 and the inner nozzle 31 have a slope, and the water sprayed outward has an angle, which can expand the coverage area of ​​the water spray and improve the fire extinguishing efficiency, as shown in the figure.

[0030] The track 1 is equipped with a track guard 5, which covers the track 1 at the top and outside. The length 03 of the upper panel of the track guard 5 is greater than the length 01 of the track, and the length 02 of the machine body is less than the length 03 of the upper panel. One end of the machine body 2 is flush with one end of the track guard 5, and the other end forms a concave portion 7 with the other end of the track guard 5, similar to a U-shape. Figures 1 to 2 As shown.

[0031] A fire hose connecting pipe 4 is installed on the body 2 at the recess 7 end of the fire-fighting robot, and a drag ring handle 6 is installed on the other end of the body 2, flush with the track guard 5. There are three drag ring handles 6, including a short drag ring handle 62 in the middle and two long drag ring handles 61 symmetrically arranged on both sides. Figure 2 As shown. The purpose of the long drag handles 6 on both sides is to allow the robot to be towed by a rescue vehicle when it malfunctions or runs out of power and cannot move. Because it is a tracked robot, dragging it with a single rope will cause uneven force on the tracks when the robot moves, making the wheels and tracks prone to deviating or even falling off, resulting in damage to the robot.

[0032] The outer side plate 52 of the track guard 5 of this fire-fighting robot is an inverted trapezoidal design, wider at the top and narrower at the bottom, with an irregularly serrated lower edge 521. Because the robot is small and easily overlooked in dark environments, potentially causing unnecessary injury or trouble, reflective strips 23 are provided on the four edges of the body panel 21. Reflective strips 53 are also provided on the outer edge of the upper panel 51 and the edges of the outer side plate 52 of the track guard 5, serving as a warning and reminder. Additionally, reflective strips can also be installed at fire hose connection points, etc.

[0033] The walking track 1 of this utility model is made of high temperature resistant and flame retardant rubber on the outer wall and an all-metal frame inside. It is designed to withstand high temperatures and can be remotely controlled to move forward, backward, and turn.

[0034] It should be noted that the above embodiments are only used to illustrate the preferred embodiments of this utility model, and are not intended to limit it. It should be pointed out that those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model, such as the arrangement method of waterway branch pipes. Therefore, all improvements and modifications made without departing from the scope of this utility model are also within the protection scope of this utility model.
