The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0019] The first embodiment of the present application is:

[0020] See also Figure 1 and Figure 2 ,in, Figure 1 It is a schematic diagram of the overall structure of the indoor fire-fighting robot of the present invention. Figure 2 It is a schematic diagram of the structure inside the cavity 102 of the present invention.

[0021] The present invention provides an indoor firefighting robot: comprising a fire monitor 101, a chassis assembly and a suspension assembly, wherein the chassis assembly comprises a cavity 102, a rear flap 103, a front flap 104, a power component and a water pipe 105, the suspension assembly comprises a driving wheel 106, a fixed suspension 107, an auxiliary wheel component and a crawler track 110, and the auxiliary wheel component comprises a supporting wheel 108 and an induction wheel 109. The above-mentioned solution solves the problem that firefighters face great safety risks when entering indoors to extinguish fires with fire hoses in their hands.

[0022] According to this specific embodiment, the rear flap 103 is hinged to the cavity 102 and is located on one side of the cavity 102, the front flap 104 is hinged to the cavity 102 and is located on a 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 is located inside the cavity 102, the number of the suspension components is two, and the two suspension components are symmetrically arranged on both sides of the cavity 102, and the fire monitor 101 is arranged on the top of the rear flap 103.

[0023] The front flap 104 and the rear flap 103 are connected to the cavity 102 by hinges, and can be flipped open separately, which is convenient for quick assembly and opening for maintenance. The two suspension components are respectively installed on both sides of the cavity 102 and locked with the cavity 102 by screws, which is convenient for assembly and maintenance. The fire monitor 101 is installed on the upper end of the rear flap 103 and locked with screws. The power component drives the suspension component to move forward and backward, and rotate 360° on the spot. The tail of the water pipe 105 adopts a special fire-fighting interface, which can be used directly by plugging in the fire-fighting pipe and connecting with the fire monitor 101. The fire monitor 101 can realize 360° rotation and +60° to -30° rotation in the front and rear directions. The top supports blooming spray and direct current spray, and also supports foam spraying to realize multi-functional fire extinguishing. The fire monitor 101 is a prior art and can be used directly.

[0024] The driving wheel 106 is arranged outside the cavity 102, the fixed suspension 107 is detachably connected to the cavity 102 and is located on a side of the cavity 102 close to the driving wheel 106, and the auxiliary wheel component is connected to the fixed suspension 107. The fixed suspension 107 is installed on the side of the cavity 102 by bolts, and the driving wheel 106 is rotatably arranged on the side of the cavity 102.

[0025] Secondly, the supporting roller 108 is rotatably connected to the fixed suspension 107 and is located below the fixed suspension 107, and the induction wheel 109 is rotatably connected to the fixed suspension 107 and is located above the fixed suspension 107. A bearing is installed on both sides of the supporting roller 108 and the induction wheel 109, and then installed on the fixed suspension 107. The middle of the fixed suspension 107 is locked with the cavity 102 by passing screws.

[0026] At the same time, the track 110 is sleeved on the outer sides of the supporting wheels 108, the inducing wheels 109 and the driving wheels 106. When the driving wheel 106 rotates, the power is transmitted through the track 110, so that the supporting wheels 108 and the inducing wheels 109 rotate. The combination of the supporting wheels 108, the inducing wheels 109 and the driving wheels 106 makes walking more stable.

[0027] Using an indoor fire-fighting robot of this embodiment, first, the two suspension assemblies are symmetrically installed on both sides of the cavity 102, and are locked with the cavity 102 by screws to ensure that the suspension assemblies are firmly connected to the cavity 102. Then, the fire monitor 101 is installed on the upper end of the rear flip cover 103, and is locked by screws to form an integral structure with the cavity 102. Next, the water pipe 105 is placed inside the cavity 102, and it is ensured that the tail thereof adopts a fire-fighting special interface for subsequent connection of the fire-fighting pipe. Finally, the front flip cover 104 and the rear flip cover 103 are connected to the cavity 102 by hinges so that they can be flipped open separately, which is convenient for subsequent assembly and maintenance work. Before the robot is ready to be put into use, it is necessary to connect the fire-fighting pipe to the fire-fighting special interface of the water pipe 105 to ensure that the fire monitor 101 is connected to the fire-fighting pipe to prepare for the fire-fighting operation. At the same time, check whether the connection of each component is firm to ensure the normal operation of the robot. The power component drives the driving wheel 106 in the suspension assembly to rotate, and the driving wheel 106 transmits power through the crawler 110, so that the supporting wheel 108 and the inducing wheel 109 also rotate. The synergistic effect of the supporting wheel 108, the inducing wheel 109 and the driving wheel 106 enables the robot to walk stably in an indoor environment, realize flexible and maneuverable movements such as forward, backward and 360° rotation on the spot, and facilitates the robot to quickly locate the fire source in a complex and changeable indoor environment. Firefighters can control the robot to move to the fire scene through 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 images to the remote controller, providing firefighters with clear on-site images so that they can make accurate fire-fighting decisions. After locating the fire source, the firefighters operate the fire monitor 101 through the remote controller to aim it at the fire source. The fire monitor 101 can realize 360° rotation and +60° to -30° rotation in the front and rear directions, and can flexibly adjust the spray angle to ensure that it is aimed at the fire source. The top supports blooming spray and direct current spray, and firefighters can choose the appropriate spray mode according to the size of the fire and the characteristics of the burning material. Blooming spray is suitable for large-area fires and can quickly reduce the temperature of the fire scene; direct current spray is suitable for concentrated spraying and can effectively extinguish local fire sources. For some special fires, such as oil fires, the fire cannon 101 also supports the foam spraying function. By spraying foam, the air can be effectively isolated and the spread of fire can be prevented. At the same time, the foam also has a certain cooling effect, which further improves the fire extinguishing effect. Firefighters can flexibly switch the spray mode according to the type of fire to achieve multi-functional fire extinguishing. There is no need to enter the fire scene by yourself to ensure your own safety. It is light in weight and can be easily carried away by two people. It can also be easily put into a large fire truck and carried with the car. It is small in size and can easily enter indoors and confined spaces for fire extinguishing, solving the shortcomings of the existing technology.

[0030] The power component of this embodiment includes a motor 201 , a driver 202 , a battery 203 and a control box 204 .

[0031] For this specific embodiment, the driver 202 and the motor 201 are both located inside the cavity 102, and the drive wheel 106 is connected to the motor 201 through a reducer. The two motors 201 independently and directly drive the drive wheels 106 to rotate through the reducers, and the drive wheels 106 then drive the track 110 to rotate, so as to move forward and backward, and rotate 360 ​​degrees in place. The connection between the motor 201 and the driver 202 is mainly realized through electrical lines. The function of the driver 202 is to convert the current of the power supply into the power signal required by the motor 201, and control the speed and direction of the motor 201.

[0032] The battery 203 is located on one side of the cavity 102 near the front flap 104, and the control box 204 is connected to the rear flap 103. The battery 203 provides power for the entire robot, and the front flap 104 can be opened to quickly remove the battery 203 for easy replacement of a new battery 203, thereby improving the endurance. A wifi module and a main controller are arranged in the control box 204 to transmit the captured video images to the remote controller, so that firefighters can remotely control and command through the remote controller, and watch the fire scene in real time, and command the robot to extinguish the fire without having to enter the fire scene themselves, thereby ensuring their own safety.

[0033] In an indoor fire-fighting robot using the present embodiment, the motor 201 is connected to the drive wheel 106 through a reducer to ensure that the drive wheel 106 can rotate independently. The battery 203 is placed on the side of the cavity 102 close to the front flip cover 104, which is convenient for quick replacement to improve the endurance. The control box 204 is connected to the rear flip cover 103, and has a built-in wifi module and a main controller. Before the robot is ready to be put into use, the fire hose is connected to the fire-dedicated interface of the water pipe 105 to ensure that the fire monitor 101 is connected to the fire hose. At the same time, check whether the connection of each component is firm to ensure the normal operation of the robot. The motor 201 drives the drive wheel 106 to rotate through the reducer, and the drive wheel 106 then drives the crawler 110 to rotate, realizing the robot's forward, backward and 360° rotation in place. This design enables the robot to be flexible and maneuverable in an indoor environment and quickly locate the fire source. Firefighters control the robot to move to the fire scene through 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 images to the remote control, providing firefighters with clear on-site images. They do not need to enter the fire scene by themselves, ensuring their own safety. It is also light in weight and can be easily carried by two people.
