Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and more specifically, to a fire-fighting robot. Background Technology

[0002] Firefighting robots, as an important branch of special service robots, are developed and applied due to the limitations of human rescue in traditional firefighting operations. With rapid urbanization, fires frequently occur in complex environments such as high-rise buildings and chemical industrial parks. Traditional firefighting methods face multiple risks, including high temperatures, dense smoke, toxic gases, and building structural collapse, directly threatening the lives of rescue personnel. Against this backdrop, firefighting robots, by integrating high-temperature resistant materials, multimodal sensor arrays, autonomous navigation algorithms, and remote control technology, are gradually achieving efficient detection and initial response to fire environments. Existing technologies can already perform tasks such as fire source location, chemical substance detection, and extinguishing small fires, significantly improving the accuracy and safety of firefighting operations and becoming one of the core equipment in intelligent firefighting systems.

[0003] However, in actual rescue operations, firefighting robots still face key technological bottlenecks. When rescue routes contain numerous continuously burning obstacles, it is difficult to quickly clear the burning materials and establish a safe rescue path. For example, stacked burning furniture, overturned burning structural components, or flowing liquid burning materials can create dynamic thermal barriers, causing the robot's navigation system to misjudge passage conditions. At the same time, existing fire extinguishing modules have insufficient coverage of three-dimensional burning materials, which can easily lead to repeated fires.

[0004] Therefore, we made improvements and proposed a firefighting robot. Utility Model Content

[0005] In order to achieve the above-mentioned objectives, this utility model provides a fire-fighting robot to improve the aforementioned problems.

[0006] The application is as follows:

[0007] include:

[0008] A base and a water storage tank installed on the base, wherein a water inlet pipe is connected to the water storage tank and a water pump is installed on the water storage tank;

[0009] The horizontal part is hinged to the free end of the base, and a drive source for the horizontal part to swing horizontally is provided at the hinge.

[0010] The vertical part is hinged to the free end of the horizontal part, and a drive source for the vertical part to swing vertically is provided at the hinge.

[0011] The support leg, hinged to the free end of the vertical section, and driven by the horizontal and vertical sections to generate displacement, has the following characteristics:

[0012] A guide cavity is formed in the support leg, and a pipe is provided between the water pump output end of the water storage tank to guide water flow to the guide cavity;

[0013] The barrier is circumferentially arranged on the contact surface between the elastic ring and the ground, and is spaced out to form channels that divert water flow;

[0014] As the support leg approaches the ground, the water flow through the guide cavity impacts the ground to form a water curtain and pushes the combustibles to both sides of the base.

[0015] Once the support leg contacts the ground, the water flow pushes the combustible materials on both sides through the channel formed by the barrier plate.

[0016] Preferably, the support leg further includes:

[0017] The control valve is located on the support leg and in the water passage path of the guide chamber;

[0018] An elastic ring is disposed on the bottom surface of the support leg, forming a cavity whose volume is reduced when compressed.

[0019] Preferably, the elastic ring has a corrugated tubular structure.

[0020] Preferably, the control valve is a pressure sensing valve, configured such that: when the support leg is not in contact with the ground, water flow is allowed to pass through the guide cavity at a first flow rate to form a water curtain; when the support leg contacts the ground and applies pressure to the elastic ring, the sensing pressure increases, and it is automatically adjusted to allow a second flow rate to pass through the channel formed by the barrier plate, wherein the second flow rate is less than the first flow rate.

[0021] Preferably, the barrier sheets are arranged in a fan shape and have gaps between them along the radial direction.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] In the scheme of this application:

[0024] To address the problems in the existing technology, this application utilizes the internal water flow guiding structure of the support leg, the pressure-sensitive valve, and the synergistic effect of the bottom elastic ring and barrier plate to automatically create an impact water curtain during the robot's descent, pushing away obstacles and fire sources in front of the landing point. After stabilizing the support, it intelligently switches to a low-flow mode, using pressurized water flow through a fan-shaped diversion channel to continuously generate outward radiating thrust, automatically pushing away combustibles on both sides of the robot to form a safety isolation zone, while simultaneously covering and cooling the landing area and surrounding ground.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] For an example, please refer to... Figure 1 , Figure 2 and Figure 3 A firefighting robot, comprising:

[0032] The base 1 and the water storage tank 2 installed on the base 1 are connected to the water storage tank 2, and the water storage tank 2 is equipped with a water inlet pipe 21 and a water pump.

[0033] The horizontal part 3 is hinged to the free end of the base 1, and a drive source for the horizontal part 3 to swing horizontally is provided at the hinge.

[0034] The vertical part 4 is hinged to the free end of the horizontal part 3, and a drive source for the vertical part 4 to swing vertically is provided at the hinge.

[0035] The support leg 5, hinged to the free end of the vertical part 4, and driven by the horizontal part 3 and the vertical part 4 to generate displacement, has the following characteristics:

[0036] The guide cavity 51 is located in the support leg 5, and a pipe is provided between it and the water pump output end of the water storage tank 2 to guide water flow to the guide cavity 51.

[0037] The barrier plate 54 is circumferentially arranged on the contact surface between the elastic ring 53 and the ground, and is spaced out to form channels for diverting water flow;

[0038] As the support leg 5 approaches the ground, the water flow through the guide cavity 51 impacts the ground to form a water curtain and pushes the combustibles to both sides of the base 1.

[0039] When the support leg 5 contacts the ground, the water flow pushes the combustible materials on both sides to be spaced out through the channel formed by the baffle plate 54.

[0040] When the firefighting robot needs to move or perform firefighting tasks, the horizontal part 3 and the vertical part 4 move in coordination under the action of the drive source at their respective hinges, precisely controlling the displacement trajectory of the support leg 5 in space. The support leg 5 begins to press down towards the target ground position. At the same time, the water pump in the water tank 2 starts, and water is pumped into the guide cavity 51 inside the support leg 5 through the pipe. As the support leg 5 falls and approaches the ground, the high-speed water jet from the end of the guide cavity 51 violently impacts the ground. The water jet instantly spreads to form a water curtain covering the area below and in front of the support leg 5. This water curtain not only effectively cools the ground that is about to be contacted and suppresses flames or high temperatures in the area, but more importantly, it generates an outward impact force, strongly pushing flammable materials such as burning debris and debris directly below the support leg 5 and along its path of movement toward the sides of the base 1, creating a relatively clean and unobstructed area for the robot to land safely, and pre-treating any fire sources near the landing point.

[0041] As the supporting leg 5 continues to descend and eventually contacts the ground, its bottom elastic ring 53 deforms due to the pressure from the ground, reducing its volume and increasing its internal pressure. At this moment, water continues to flow from the guide cavity 51. Because the supporting leg 5 has compacted the ground, the water can no longer freely impact and spread downwards to form a large water curtain as it did during the descent. Instead, the water is guided by the spaced channels formed by the baffles 54 distributed circumferentially on the bottom surface of the elastic ring 53. These channels force the water to change direction, transforming its original vertical downward impact into a radial jet that radiates outwards, horizontally, or obliquely to both sides along the channels. This diversion design allows the water energy to be efficiently concentrated and guided.

[0042] Once the support leg 5 is fully pressed onto the ground and becomes a stable fulcrum for the robot, the water flow diverted from the channel of the barrier plate 54 is continuously and stably sprayed powerfully to the left and right sides of the support leg 5, that is, to the far side of the base 1. It continuously pushes combustibles on both sides of the base 1, including debris previously pushed there by the water curtain and new combustibles from the surrounding area, further away from the robot body, creating and maintaining a safe, flame-free, and obstacle-free isolation zone around the robot body. At the same time, due to the increased pressure, these diverted water flows also create gaps between combustibles that have been or have not been pushed away, differentiating the combustion conduction path of the combustibles, thus weakening the combustion effect, suppressing reignition, and protecting the support legs 5 themselves, especially the elastic ring 53, from direct exposure to overheated ground or residual fire. In addition, by adjusting the azimuth angle of the support legs 5 through the horizontal swing drive source of the horizontal part 3, the direction of the diverted spray can be dynamically changed, actively clearing fire sources and obstacles on the sides of the robot's travel route or the side of the target area, greatly enhancing the robot's mobility, stability, and continuous combat capability in complex fire environments, effectively improving the robot's fire extinguishing efficiency and reducing the degree of flame combustion.

[0043] Support leg 5 also includes:

[0044] The control valve 52 is installed on the support leg 5 and located in the water passage of the guide cavity 51. The control valve 52 directly intervenes in the water flow path of the guide cavity 51, providing a core actuator for accurately controlling the water flow state of the support leg 5 at different working stages.

[0045] The elastic ring 53 is set on the bottom surface of the support leg 5, forming a cavity with reduced volume under compression. When the support leg 5 touches the ground and is pressed, it deforms and the volume shrinks. This not only provides good grounding buffer and adaptability, but the compression of its internal space also directly leads to an increase in the pressure of the water flowing through it, providing the necessary boosting power source for the subsequent water flow to be powerfully sprayed laterally through the channel of the baffle plate 54.

[0046] The elastic ring 53 has a corrugated tubular structure, which gives the elastic ring 53 excellent and repeatable axial compression elasticity, ensuring that the expected deformation can be stable and reliable during the repeated contact of the support leg 5 with the ground. Its regular pleated structure can also play a certain role in guiding and suppressing turbulence when water flows through it, helping the water flow to flow more smoothly and concentratedly to the channel formed by the baffle plate 54.

[0047] Control valve 52 is a pressure sensing valve, configured such that: when the support leg 5 is not in contact with the ground, water flow is allowed to pass through the guide cavity 51 at a first flow rate to form a water curtain; when the support leg 5 contacts the ground and applies pressure to the elastic ring 53, the sensing pressure increases and automatically adjusts to allow a second flow rate to pass through the channel formed by the baffle plate 54, the second flow rate being less than the first flow rate;

[0048] During the initial stage before the support leg 5 touches the ground, a low-pressure signal keeps the valve fully open, allowing a large flow of water to directly hit the ground, forming a powerful water curtain to push away combustibles and cool the landing point. Once the support leg 5 touches the ground and compacts, the pressure on the elastic ring 53 causes a significant increase in the water system pressure. A high-pressure signal triggers the valve to automatically reduce its opening. At the same time, the elastic ring 53 deforms and closes the direct spray nozzle of the guide chamber 51, forcing the main water flow to change course and pass through the barrier plate 54 channel with a smaller flow rate. This adaptive switching precisely matches the functional requirements of different stages. Opening the landing point requires impact force, or stable support requires continuous lateral cleaning and water conservation. The pressurization effect generated by the pressure allows even a small flow of water to form an effective lateral jet force within the barrier plate 54 channel.

[0049] The baffles 54 are arranged in a fan shape with gaps between them along the radial direction. When the water flows through the fan-shaped gaps, it will block the flow direction, reduce the damage of the water flow impact to the baffles 54, and extend its service life.

[0050] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
