Technical Field

[0001] This utility model relates to the field of fire extinguishing robot technology, and in particular to a three-dimensional fire extinguishing robot. Background Technology

[0002] In fire rescue scenarios, timely and effective firefighting is crucial to reducing casualties and property damage. As an intelligent device capable of autonomous or remote-controlled firefighting operations, the 3D firefighting robot can replace manual labor in complex and dangerous fire environments, improving firefighting efficiency and safety.

[0003] Chinese patent document CN221412096U discloses a fire-fighting robot, including a base, a water tank at the top of the base, a tracked moving assembly at the bottom of the base, a rotating assembly on the right side of the top of the base, a fixed frame at the top of the rotating assembly, a swinging assembly within the inner cavity of the fixed frame, a nozzle on the swinging assembly, a water pump at the top of the water tank, an input end of the water pump extending to the bottom of the inner cavity of the water tank, and an output end of the water pump connected to the nozzle via a water hose. This fire-fighting robot, through the combined action of the rotating and swinging assemblies, allows the nozzle to swing up, down, left, and right, improving the flexibility of the device during use and solving the problem that existing fire-fighting robots cannot swing the nozzle up and down in actual use, resulting in significant limitations.

[0004] The existing technology has the following problems: Although the above-mentioned utility model allows the nozzle to swing up and down and left and right, it lacks effective lifting and lowering adjustment capabilities, cannot adapt to fire sources at different heights, and is difficult to meet diverse fire extinguishing needs. Furthermore, the direct up-and-down swinging of the nozzle by the motor results in insufficient adjustment precision, making it difficult to cope with complex fire source locations. Utility Model Content

[0005] This utility model provides a three-dimensional fire extinguishing robot to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A three-dimensional fire extinguishing robot includes a drive box, a support frame mounted on the upper part of the drive box, a liquid storage tank installed inside the support frame, a feed inlet mounted on the upper part of the liquid storage tank, a pump body mounted on the lower part of the liquid storage tank, a support plate installed inside the support frame, a lifting mechanism installed on the outer side of the support plate, an angle adjustment mechanism I installed on the upper part of the support plate, a fixing block installed above the angle adjustment mechanism I, and a nozzle installed on the outer side of the fixing block. The drive box has a drive wheel at the bottom, heat dissipation fins on the outside of the drive box, an alarm on the outside of the support frame, a sensor array in the middle of the drive box, and a camera above the sensor array.

[0007] Preferably, the angle adjustment mechanism includes a support platform, which is installed in the middle of a support plate. The fixing block is installed on the upper part of the support platform. A second motor is installed inside the support plate. A reciprocating lead screw is installed at the output end of the second motor. A second slider is provided on the outer periphery of the reciprocating lead screw. A toothed plate is installed on the upper part of the second slider. The toothed plate meshes with the outer periphery of the support platform. The angle adjustment mechanism is provided on the upper part of the support platform.

[0008] Preferably, the second angle adjustment mechanism includes an electric push rod, which is installed inside the support platform. A connecting plate is installed at the telescopic end of the electric push rod. A support rod is installed on the outside of the nozzle. The end of the support rod away from the nozzle is installed on the outside of the fixing block. A sliding plate is installed inside the support rod. The lower end of the sliding plate is installed above the connecting plate.

[0009] Preferably, the lifting mechanism includes a slider, which is installed on the outside of the support plate. A threaded rod is provided in the middle of the slider, and a transmission wheel is installed on the upper part of the threaded rod. A toothed belt is meshed with the outer periphery of the transmission wheel. A motor is installed on the upper part of the support frame, and the threaded rod is installed at the output end of the motor.

[0010] Preferably, a slide rod is installed inside the slider, and buffer plates are installed at both ends of the slide rod, and a buffer spring is installed on the outer periphery of the slide rod.

[0013] Preferably, a pressure gauge is installed on the upper part of the liquid storage tank, and a liquid level gauge is installed on the outer side of the liquid storage tank.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a three-dimensional fire extinguishing robot. By setting up a lifting mechanism, a motor drives a threaded rod to rotate, and through a transmission wheel and toothed belt, multiple threaded rods rotate synchronously, driving the slider to rise and fall smoothly along the sliding rod. This allows for flexible adjustment of the height of the support plate and its components, enabling it to adapt to fire sources of different heights and meet the fire extinguishing needs of fires at different heights. At the same time, the sliding rod provides guidance for the movement of the slider, and the buffer plate and buffer spring work together to reduce the impact of the slider's movement, prevent violent collisions, protect the lifting mechanism components, and extend their service life.

[0015] 2. This utility model provides a three-dimensional fire extinguishing robot. By setting up angle adjustment mechanism one and angle adjustment mechanism two, motor two drives the reciprocating screw to rotate, so that the slider drives the toothed plate to move linearly, driving the support platform to rotate around the central axis, thereby realizing the horizontal angle adjustment of the nozzle; the electric push rod pushes the slide plate to slide inside the support rod through the connecting plate, thereby driving the nozzle to finely adjust the vertical spray angle around the installation point. The two work together to flexibly adjust the spray direction, expand the fire extinguishing coverage, enhance the adaptability to fire sources of different heights and locations, and improve the fire extinguishing effect.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1 - Figure 5 As shown, the three-dimensional fire extinguishing robot includes a drive box 1, a support frame 2 installed on the upper part of the drive box 1, a liquid storage tank 7 installed inside the support frame 2, a feed inlet 8 installed on the upper part of the liquid storage tank 7, a pump body 9 installed on the lower part of the liquid storage tank 7, a support plate 3 installed inside the support frame 2, a lifting mechanism 4 installed on the outer side of the support plate 3, an angle adjustment mechanism 5 installed on the upper part of the support plate 3, a fixing block 10 installed above the angle adjustment mechanism 5, and a nozzle 11 installed on the outer side of the fixing block 10. The lower part of the drive box 1 is provided with drive wheels 16, the outer side of the drive box 1 is provided with heat dissipation fins 18, the outer side of the support frame 2 is provided with an alarm 19, the middle part of the drive box 1 is provided with a sensor array 14, and the upper part of the sensor array 14 is provided with a camera 15.

[0020] It should be noted that the drive box 1 is the core basic component of the three-dimensional fire extinguishing robot. It provides the power required for operation and supports many key components, serving as a crucial support for the robot's stable operation. The support frame 2 provides a stable mounting framework for other components, ensuring the orderly installation and coordinated operation of each component. The liquid storage tank 7 stores the fire extinguishing liquid, and the inlet 8 facilitates quick replenishment, ensuring the robot is always ready to extinguish fires. The pump body 9 is the power source for delivering the fire extinguishing liquid, capable of extracting, pressurizing, and spraying the liquid into the fire area. The support plate 3 provides an installation platform for the lifting mechanism 4 and the angle adjustment mechanism 5, ensuring their stable operation. The lifting mechanism 4 can flexibly adjust the height of the support plate 3 and its components to adapt to fire sources of different heights. The angle adjustment mechanism 5 can adjust the angle of the fixing block 10, changing the horizontal spray angle of the nozzle 11 and expanding the fire extinguishing range. The fixing block 10 provides a stable installation position for the nozzle 11, preventing shaking during spraying. The nozzle 11 is the final spray outlet for the fire extinguishing liquid, enabling precise fire extinguishing.

[0021] The drive wheels 16 are the robot's movement actuators, propelling the robot across the ground to quickly reach the fire scene. Heat dissipation fins 18 increase the heat dissipation area of ​​the drive housing 1, rapidly dissipating internal heat, preventing component performance degradation or damage, and ensuring stable operation over extended periods. The alarm 19 sounds an alarm when a fire or anomaly is detected, alerting nearby personnel to take appropriate measures. The sensor array 14, composed of various sensors, can detect ambient temperature, smoke concentration, and other information in real time and transmit this data to the main controller, providing a basis for fire assessment and action planning. The camera 15 captures environmental images and videos, allowing operators to observe the scene remotely and direct firefighting operations, improving efficiency and accuracy.

[0022] like Figure 4 and Figure 5As shown, the angle adjustment mechanism 5 includes a support platform 51, which is installed in the middle of the support plate 3. A fixing block 10 is installed on the upper part of the support platform 51. A motor 55 is installed inside the support plate 3. A reciprocating screw 54 is installed at the output end of the motor 55. A slider 53 is provided on the outer periphery of the reciprocating screw 54. A toothed plate 52 is installed on the upper part of the slider 53. The toothed plate 52 meshes with the outer periphery of the support platform 51. An angle adjustment mechanism 6 is provided on the upper part of the support platform 51.

[0023] It should be noted that the support platform 51 provides the mounting base for the fixed block 10 and enables angle adjustment. Motor 2 55 can precisely control the rotation speed and direction, providing power for the rotation of the reciprocating screw 54. The reciprocating screw 54 rotates under drive, causing slider 2 53 to perform reciprocating linear motion. Slider 2 53 connects the reciprocating screw 54 and the toothed plate 52, converting the rotation into linear motion of the toothed plate 52. Both ends of the axis of the reciprocating screw 54 are equipped with spiral steel strip protective sleeves. The toothed plate 52 meshes with the outer peripheral gear structure of the support platform 51, causing the support platform 51 to rotate around its central axis during movement, thus achieving horizontal angle adjustment of the fixed block 10 and its nozzle 11. This allows the robot to flexibly adjust the spray direction. A protective sleeve is installed above the support plate 3 to protect the internal transmission components. Angle adjustment mechanism 2 6 can further adjust the vertical spray angle of the nozzle 11, enhancing adaptability to fire sources of different heights and positions.

[0024] like Figure 4 As shown, the angle adjustment mechanism 26 includes an electric push rod 62, which is installed inside the support platform 51. A connecting plate 63 is installed at the telescopic end of the electric push rod 62. A support rod 61 is installed on the outside of the nozzle 11. The end of the support rod 61 away from the nozzle 11 is installed on the outside of the fixing block 10. A sliding plate 64 is installed inside the support rod 61. The lower end of the sliding plate 64 is installed above the connecting plate 63.

[0025] It should be noted that the electric push rod 62 provides power to the connecting plate 63. The connecting plate 63 transmits the telescopic motion to the sliding plate 64, realizing motion transmission and conversion. The support rod 61 provides stable support for the nozzle 11, preventing it from wobbling or falling off during angle adjustment. The sliding plate 64 slides within the support rod 61, changing its relative position with the support rod 61, driving the nozzle 11 to rotate around the mounting point, achieving fine-tuning of the vertical angle, enabling the robot to spray extinguishing liquid more accurately and improving the fire extinguishing effect.

[0026] like Figure 3 and Figure 4As shown, the lifting mechanism 4 includes a slider 45, which is installed on the outside of the support plate 3. A threaded rod 44 is provided in the middle of the slider 45, and a transmission wheel 42 is installed on the upper part of the threaded rod 44. A toothed belt 43 is meshed with the outer periphery of the transmission wheel 42. A motor 41 is installed on the upper part of the support frame 2, and the threaded rod 44 is installed at the output end of the motor 41.

[0027] It should be noted that slider 45 is the lifting actuator for support plate 3. It moves up and down along threaded rod 44 as the threaded rod rotates, thus lifting support plate 3. Transmission wheel 42 is connected to motor 41 via toothed belt 43, transmitting power to threaded rod 44, causing multiple threaded rods 44 to rotate synchronously, ensuring smooth lifting of support plate 3. Toothed belt 43 accurately transmits power to motor 41, causing transmission wheel 42 to rotate synchronously. Motor 41 can control the rotation speed and direction, providing power to lifting mechanism 4, enabling flexible lifting of support plate 3 to meet fire extinguishing needs at different heights.

[0028] like Figure 4 As shown, a slide rod 46 is installed inside the slider 45, and buffer plates 47 are installed at both ends of the slide rod 46. A buffer spring 48 is installed on the outer periphery of the slide rod 46.

[0029] It should be noted that the slide bar 46 guides the movement of the slider 45, ensuring its stable movement along a straight line and preventing deviation or jamming. The buffer plate 47 acts as a buffer when the slider 45 moves to its extreme position. The buffer spring 48 absorbs and releases energy, generating elasticity when compressed to reduce impact and prevent the slider 45 from violently colliding with the support frame 2, thus protecting the lifting mechanism 4 components. During reverse movement, the buffer spring 48 releases its elasticity, helping the slider 45 move smoothly, reducing impact, and extending the service life of the lifting mechanism 4.

[0030] like Figure 2 As shown, the drive box 1 contains a main controller and a battery, and a charging interface 17 is provided on the outside of the drive box 1.

[0031] It should be noted that the main controller is the robot's "brain." It receives information such as ambient temperature, smoke concentration, and on-site images from components like the sensor array 14 and camera 15. After analysis and processing, it sends precise control commands to various actuators (such as motor 41, motor 55, electric push rod 62, and pump 9) to enable automated robot operation. This allows the robot to autonomously perform actions such as movement, angle adjustment, and spraying fire extinguishing liquid according to the fire scene conditions. The battery is the robot's energy storage device. During charging, it converts electrical energy into chemical energy for storage. During operation, it provides stable power support to various components, ensuring the robot can continuously operate and complete firefighting tasks. The charging interface 17 is the connection channel between the battery and an external power source. Operators can use it to charge the battery with a suitable charger, ensuring the robot always has sufficient power for operation.

[0032] like Figure 1 As shown, a flexible hose is installed at the output end of the pump body 9, and a spring tube is installed inside the fixing block 10.

[0033] It should be noted that the hose has good flexibility and pressure resistance, enabling it to smoothly guide the extinguishing liquid delivered by the pump body 9 from the storage tank 7 to the spring tube inside the fixing block 10. The spring tube has a certain degree of elasticity and flexibility, and can freely deform according to the angle of the nozzle 11, keeping the extinguishing liquid delivery channel unobstructed, ensuring a stable and continuous delivery of the extinguishing liquid to the nozzle 11, and guaranteeing the normal operation of the fire extinguishing work.

[0034] like Figure 2 As shown, a pressure gauge 13 is installed on the upper part of the liquid storage tank 7, and a liquid level gauge 12 is installed on the outside of the liquid storage tank 7.

[0035] It should be noted that pressure gauge 13 can display the real-time pressure of the extinguishing liquid in the storage tank 7. Operators can observe the reading to understand the liquid pressure and determine whether the pump 9 is working properly. If the pressure is too low, timely measures should be taken, such as checking whether the liquid is insufficient or whether the pump 9 is malfunctioning. Liquid level gauge 12 can visually display the liquid level in the storage tank 7. Operators can use the display to understand the remaining amount in a timely manner and add liquid when it is insufficient, ensuring that the robot can continue to carry out firefighting operations and avoiding the impact of liquid depletion on the firefighting effect.

[0036] The working principle of this invention is as follows: The main controller acts as the "brain" of the robot. It acquires information such as ambient temperature and smoke concentration in real time through the sensor array 14, and combines this with on-site images captured by the camera 15 to analyze and judge the fire situation and plan the action path. When a fire is detected, the main controller instructs the drive wheels 16 to drive the robot to the scene quickly, while the heat dissipation fins 18 continuously dissipate heat from the drive box 1 to ensure stable operation of the equipment.

[0037] During fire extinguishing, the extinguishing liquid stored in the storage tank 7 through the inlet 8 is pressurized by the pump body 9 and then delivered through a hose to the spring tube inside the fixed block 10, and finally precisely sprayed onto the fire source by the nozzle 11. Motor 41 drives the threaded rod 44 to rotate, achieving synchronous operation of multiple threaded rods through the transmission wheel 42 and toothed belt 43, which in turn drives the slider 45 to smoothly rise and fall along the slide rod 46, thereby adjusting the height of the support plate 3 to adapt to different fire source positions. The buffer spring 48 and the buffer plate 47 work together to reduce the impact of slider 45 movement and extend the equipment's lifespan.

[0038] For angle adjustment, motor 2 55 drives reciprocating screw 54 to rotate, causing slider 2 53 to drive toothed plate 52 to move linearly, which in turn drives support platform 51 to rotate around the central axis, realizing horizontal angle adjustment of nozzle 11; electric push rod 62 pushes slide plate 64 to slide within support rod 61 through connecting plate 63, driving nozzle 11 to finely adjust vertical spray angle around the installation point, and the two work together to expand the fire extinguishing coverage. Pressure gauge 13 and liquid level gauge 12 monitor the status of liquid storage tank 7 in real time to ensure sufficient fire extinguishing liquid and normal operation of pump body 9. Alarm 19 sounds an alarm when abnormality is detected, and charging interface 17, together with battery, continuously powers all components, ensuring that the robot can autonomously complete fire extinguishing tasks such as movement, spraying, and multi-angle adjustment.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
