[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The first embodiment of this application is as follows:

[0020] Please see Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the overall structure of the indoor fire-fighting robot of this utility model. Figure 2 This is a schematic diagram of the internal structure of the cavity 102 of this utility model.

[0021] This utility model provides an indoor firefighting robot, including a fire monitor 101, a chassis assembly, and a suspension assembly. The chassis assembly includes a cavity 102, a rear flip-up cover 103, a front flip-up cover 104, a power component, and a water pipe 105. The suspension assembly includes a drive wheel 106, a fixed suspension 107, an auxiliary wheel assembly, and tracks 110. The auxiliary wheel assembly includes a support wheel 108 and an inducer wheel 109. The aforementioned solution solves the problem of the great safety risks faced by firefighters who rely on hand-held fire hoses to enter indoor areas for firefighting.

[0022] In this specific embodiment, the rear flap 103 is hinged to the cavity 102 and located on one side of the cavity 102; the front flap 104 is hinged to the cavity 102 and located on the side of the cavity 102 away from the rear flap 103; the power component is connected to the cavity 102; the water pipe 105 is connected to the fire monitor 101 and located inside the cavity 102; there are two suspension assemblies, which are symmetrically arranged on both sides of the cavity 102; and the fire monitor 101 is located on the top of the rear flap 103.

[0023] The front flip cover 104 and the rear flip cover 103 are connected to the cavity 102 via hinges and can be opened independently for quick assembly and maintenance. The two suspension assemblies are respectively installed on both sides of the cavity 102 and locked to the cavity 102 with screws for easy assembly and maintenance. The fire monitor 101 is installed on the upper end of the rear flip cover 103 and locked with screws. The power component drives the suspension assembly to move forward, backward, and rotate 360° in place. The tail of the water pipe 105 adopts a fire-specific interface, which can be directly used by inserting a fire hose and is connected to the fire monitor 101. The fire monitor 101 can rotate 360° and rotate forward and backward by +60° to -30°. The top supports both open-spray and direct-flow spraying, and also supports foam spraying for multi-functional fire extinguishing. The fire monitor 101 is existing technology and can be used directly.

[0024] The drive wheel 106 is located on the outer side of the cavity 102. The fixed suspension 107 is detachably connected to the cavity 102 and is located on the side of the cavity 102 near the drive wheel 106. The auxiliary wheel component is connected to the fixed suspension 107. The fixed suspension 107 is bolted to the side of the cavity 102, and the drive wheel 106 is rotatably mounted on the side of the cavity 102.

[0025] Secondly, the support roller 108 is rotatably connected to the fixed suspension 107 and located below the fixed suspension 107, while the guide roller 109 is rotatably connected to the fixed suspension 107 and located above the fixed suspension 107. Each of the support roller 108 and the guide roller 109 is equipped with a bearing on both sides before being mounted on the fixed suspension 107. The fixed suspension 107 is then locked to the cavity 102 by screws passing through it.

[0026] Meanwhile, the track 110 is fitted over the outer side of the support roller 108, the idler wheel 109, and the drive wheel 106. When the drive wheel 106 rotates, the rotation is transmitted through the track 110, causing the support roller 108 and the idler wheel 109 to rotate. The combination of the support roller 108, the idler wheel 109, and the drive wheel 106 makes the movement more stable.

[0027] Using an indoor firefighting robot according to this embodiment, firstly, the two suspension assemblies are symmetrically installed on both sides of the cavity 102 and locked to the cavity 102 with screws to ensure a firm connection between the suspension assemblies and the cavity 102. Then, the fire monitor 101 is installed on the upper end of the rear flip cover 103 and locked with screws to form an integral structure with the cavity 102. Next, the water pipe 105 is placed inside the cavity 102, ensuring that its tail end uses a fire-specific interface for subsequent connection to fire hoses. Finally, the front flip cover 104 and the rear flip cover 103 are connected to the cavity 102 via hinges, allowing them to be flipped open independently for convenient subsequent assembly and maintenance. Before the robot is put into use, the fire hose needs to be connected to the fire-specific interface of the water pipe 105 to ensure that the fire monitor 101 is connected to the fire hose, preparing for firefighting operations. Simultaneously, the connections of all components are checked for firmness to ensure the normal operation of the robot. The power component drives the drive wheel 106 in the suspension assembly to rotate. The drive wheel 106 transmits power through the track 110, causing the support roller 108 and the idler wheel 109 to also rotate. The coordinated action of the support roller 108, idler wheel 109, and drive wheel 106 enables the robot to walk stably in an indoor environment, achieving flexible and maneuverable movements such as forward, backward, and 360° rotation in place, facilitating the robot's rapid location of fire sources in complex and changing indoor environments. Firefighters can control the robot to move to the fire scene via a remote controller and use the camera and lighting in front of the robot to observe the fire scene in real time and accurately locate the fire source. The camera transmits the captured video footage to the remote controller, providing firefighters with clear images of the scene to make accurate firefighting decisions. After locating the fire source, firefighters operate the fire monitor 101 via the remote controller to aim it at the fire source. The fire monitor 101 can rotate 360° and rotate forward and backward by +60° to -30°, flexibly adjusting the spray angle to ensure it is aimed at the fire source. The top supports both wide-area spraying and direct-flow spraying, allowing firefighters to select the appropriate spray mode based on the fire size and the characteristics of the burning material. Wide-area spraying is suitable for large-scale fires, rapidly reducing the temperature at the fire scene; direct-flow spraying is suitable for concentrated spraying, effectively extinguishing localized fires. For some special fires, such as oil fires, the fire monitor 101 also supports foam spraying. By spraying foam, air can be effectively isolated, preventing the spread of fire. Simultaneously, the foam also has a cooling effect, further improving the fire extinguishing effect. Firefighters can flexibly switch spraying modes according to the type of fire, achieving multi-functional fire extinguishing. Firefighters do not need to enter the fire scene themselves, ensuring their own safety. Furthermore, it is lightweight, easily carried by two people, and easily placed inside a large fire truck for transport. Its compact size allows for easy entry into indoor and enclosed spaces for fire extinguishing, overcoming the shortcomings of existing technologies.

[0028] The second embodiment of this application is as follows:

[0029] Based on the first embodiment, please refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the overall structure of the indoor fire-fighting robot of this utility model. Figure 2 This is a schematic diagram of the internal structure of the cavity 102 of this utility model.

[0030] The power components in this embodiment include a motor 201, a driver 202, a battery 203, and a control box 204.

[0031] In this specific embodiment, both the driver 202 and the motor 201 are located inside the cavity 102. The drive wheel 106 is connected to the motor 201 via a reducer. The two motors 201 independently drive the drive wheels 106 to rotate via the reducers. The drive wheels 106 then drive the track 110 to rotate, achieving forward and backward movement, as well as 360° rotation in place. The connection between the motor 201 and the driver 202 is mainly achieved through electrical wiring. The driver 202 converts the current from the power supply into the electrical signal required by the motor 201 and controls the speed and direction of the motor 201.

[0032] The battery 203 is located inside the cavity 102 near the front flip cover 104, and the control box 204 is connected to the rear flip cover 103. The battery 203 provides power to the entire robot. Opening the front flip cover 104 allows for quick removal of the battery 203 for easy replacement, improving battery life. The control box 204 contains a Wi-Fi module and a main controller, transmitting captured video footage to a remote controller. Firefighters can remotely control and command the robot, monitor the fire scene in real time, and direct it to extinguish the fire without entering the fire area themselves, ensuring their own safety.

[0033] In this embodiment of an indoor firefighting robot, the motor 201 is connected to the drive wheel 106 via a reducer, ensuring that the drive wheel 106 can rotate independently. The battery 203 is placed on the side of the cavity 102 near the front flip cover 104 for easy and quick replacement to improve battery life. The control box 204 is connected to the rear flip cover 103 and has a built-in Wi-Fi module and main controller. Before the robot is put into use, the fire hose is connected to the fire-specific interface of the water pipe 105 to ensure that the fire monitor 101 is connected to the fire hose. At the same time, the connections of each component are checked to ensure the normal operation of the robot. The motor 201 drives the drive wheel 106 to rotate via the reducer, and the drive wheel 106 then drives the track 110 to rotate, realizing the robot's forward, backward, and 360° rotation in place. This design allows the robot to move flexibly in indoor environments and quickly locate fire sources. Firefighters control the robot to move to the fire scene via a remote controller and use the camera and lighting in front of the robot to observe the fire scene in real time and accurately locate the fire source. The camera transmits captured video footage to a remote control, providing firefighters with clear images of the scene. Firefighters don't need to enter the fire scene themselves, ensuring their safety. It's also lightweight, easily carried by two people, and can be easily placed inside a large fire truck for transport. Its compact size allows for easy entry into indoor and enclosed spaces for firefighting, overcoming the shortcomings of existing technology.
