Description

Technical Field

[0001] This invention relates to the field of intelligent fire protection technology, specifically to an unmanned indoor fire-fighting robot. Background Technology

[0002] Unmanned indoor firefighting robots are intelligent firefighting equipment that can perform fire extinguishing, monitoring, and alarm tasks in specific indoor environments without direct human operation. These robots can walk autonomously, explore and navigate to the fire source, and extinguish fires without human intervention. They can identify fires, smoke, and other potential hazards through sensors and cameras, respond to fires in a timely manner, and are equipped with necessary fire extinguishing devices. They can communicate with the central control system or other equipment to transmit on-site information in real time and execute tasks according to instructions. They are mainly used in places that require rapid fire response, such as data centers, large warehouses, and museums. Current mobile firefighting robots move along the ground during fire source monitoring and patrol. However, they cannot detect fire sources in a timely manner when there are obstructions in indoor spaces or when the fire source is located at a high position. This results in a lack of timeliness in fire monitoring. Furthermore, they cannot quickly and accurately reach the designated location or quickly isolate the fire area during firefighting response, thus compromising firefighting efficiency and effectiveness. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an unmanned indoor firefighting robot. This solves the problem that current mobile firefighting robots, while moving along the ground during fire source monitoring and patrol, cannot detect fires in a timely manner when there are obstructions or the fire source is high in the indoor space. This results in a lack of real-time fire monitoring and an inability to quickly and accurately reach the designated location and isolate the fire area during firefighting response, thus compromising firefighting efficiency and effectiveness.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an unattended indoor fire-fighting robot, comprising a longitudinal electric slide rail, with guide rails arranged parallel to each other on the longitudinal electric slide rail, and a transverse electric slide rail vertically connected to the top of the longitudinal electric slide rail and the guide rail, with the same end of the longitudinal electric slide rail and the guide rail connected to a fixed frame, and a mounting plate connected to the bottom sliding end of the transverse electric slide rail; a storage box for winding and storing fire hoses is provided on one side of the fixed frame, with the fire hoses passing through and out of the storage box; A pressure box is connected to the top side of the mounting plate via a support box. A fire extinguishing nozzle is connected to the discharge end of one side of the pressure box. A monitoring box is installed on the other side of the top of the mounting plate. A monitoring instrument for fire monitoring is installed at the bottom of the monitoring box.

[0005] As a preferred technical solution of the unattended indoor fire-fighting robot of the present invention, a rotary motor is installed inside the support box, a sleeve is connected to the bottom transmission end of the rotary motor, a drive motor is embedded in the top of the inner side of the sleeve, a threaded cylinder is connected to the bottom transmission end of the drive motor, a threaded seat is threadedly connected to the threaded cylinder, and a support rod is fixedly connected to the bottom end of the threaded seat. A sliding square plate that fits and slides along the inner wall of the sleeve is connected to the bottom of the support rod. The bottom side of the support rod is rotatably connected to a rotating tube via a swivel. The bottom of the rotating tube is evenly provided with distribution holes. The side of the sleeve is provided with a through groove corresponding to the rotation path of the rotating tube. A traction cable is tied to one end of the rotating tube, and the other end of the traction cable is limited and wound in the limiting winding box at the top of the threaded cylinder. A connecting hose is connected to one end of the rotating tube. The connecting hose passes through the bottom of the sleeve and is connected to the conveyor box fixed to the side of the sleeve.

[0006] As a preferred technical solution of the unattended indoor fire-fighting robot of the present invention, the longitudinal electric slide rail, guide rail and fixing frame are all installed on the indoor ceiling according to the indoor layout, and the longitudinal electric slide rail and the transverse electric slide rail are both lead screw slide rails, driven by a drive motor. The monitoring instruments specifically include a visible light camera, an infrared thermal imager, and a smoke detector. The visible light camera, infrared thermal imager, and smoke detector are all connected to the central controller inside the monitoring box. The fire water pipe is connected to the booster pump inside the booster box, and the output end of the booster pump is connected to the fire extinguishing nozzle through a steel pipe. The delivery box delivers fire extinguishing dry powder to the connecting hose in the form of gas-solid two-phase flow through the high-pressure gas cylinder inside. The high-pressure gas cylinder is filled with high-pressure inert gas. Both the fire water pipe and the connecting hose are made of flexible metal braided hose.

[0007] As a preferred technical solution of the unattended indoor fire-fighting robot of the present invention, the side of the sliding square plate is provided with a slot corresponding to the rotating pipe, the threaded cylinder drives the limiting winding box to rotate synchronously, and a guide groove for the traction cable to pass through is provided on one side of the limiting winding box. The bottom of the threaded cylinder is provided with a limiting seat to limit the threaded seat. When the threaded seat contacts the limiting seat, the rotating tube deflects to a horizontal position under its own weight. After the support rod is fully retracted into the threaded cylinder, the rotating tube rotates to a vertical position under the traction of the traction cable.

[0008] As a preferred technical solution of the unattended indoor fire-fighting robot of the present invention, a guide ring for traction and guidance of fire water pipe is connected to the top side of the horizontal electric slide rail, a roller for winding and storing fire water pipe is provided in the storage box, end boxes are installed on both sides of the inner side wall of the storage box, the two ends of the roller are rotatably connected to the storage box through a coupling shaft, and a torsion spring is sleeved on the outer side of the extension end of the coupling shaft, and an end cap is provided on the outer end of the storage box at the position outside the torsion spring. A rotating gear disk is connected to the connecting shaft at a position inside the end box. A magnetic block is installed on the helical teeth of the rotating gear disk. An internal gear ring is installed on the inner wall of the end box. An electromagnet is installed on the helical teeth of the internal gear ring corresponding to the magnetic block. A support plate is rotatably connected to the inner side of the end box to limit and support the rotating gear disk. An adsorption block is provided on the edge of the support plate corresponding to the electromagnet.

[0009] As a preferred technical solution of the unattended indoor fire-fighting robot of the present invention, the bottom of the guide ring is connected to the top of the transverse electric slide rail through the universal ball joint seat, one end of the fire water pipe is inserted into the storage box and coiled on the roller, and the other end is inserted out of the storage box and connected to the fire hydrant water pipe. When the connecting shaft rotates, it drives the torsion spring on its outer side to rotate, and the connecting shaft synchronously drives the rotating gear disk to rotate in the end box. The support plate resists and restricts the oblique teeth of the rotating gear disk in a natural hanging state.

[0010] As a preferred technical solution of the unattended indoor fire-fighting robot of the present invention, when the electromagnet is energized, it drives the magnetic block and the rotating toothed disk to deflect through magnetic repulsion, and attracts the adsorption block through magnetic attraction, thereby releasing the adsorption block from restricting the rotating toothed disk.

[0011] As a preferred technical solution of the unattended indoor fire-fighting robot of the present invention, the top of the longitudinal electric slide rail and the guide rail is provided with a rubber sheet, and the longitudinal electric slide rail and the guide rail are driven by the drive slider inside to move the transverse electric slide rail. The sides of the longitudinal electric slide rail and the guide rail are provided with side boxes, and the side boxes are embedded with detachable panels. A liquid storage bladder is embedded in the inner side of the panel, and a cotton block is provided at the extrusion end position on one side of the liquid storage bladder at the edge of the panel. Extrusion grooves are evenly arranged in the cotton block, and protrusions are provided on both sides of the drive slider.

[0012] As a preferred technical solution of the unattended indoor fire-fighting robot of the present invention, the rubber sheet is set at the top two sides of the longitudinal electric slide rail and the guide rail, the side box is provided with a groove, the panel is tightly embedded in the groove, and the contact position between the panel and the groove is provided with an anti-slip sheet.

[0013] As a preferred technical solution of the unattended indoor fire-fighting robot of the present invention, the liquid storage bladder is provided with viscous lubricating fluid, and fine holes are uniformly arranged on the side of the liquid storage bladder near the cotton block. The extrusion groove penetrates the interior of the cotton block. When the drive slider slides, the protrusions on both sides of it squeeze the cotton block.

[0014] Compared with existing technologies, the present invention provides an unattended indoor firefighting robot, which has the following advantages: 1. The rotary motor drives the sleeve to rotate, and the drive motor drives the threaded cylinder to rotate, which facilitates the raising and lowering of the threaded seat, support rod, sliding square plate and rotating seat. This allows for easy adjustment of the height of the rotating tube to reach the fire extinguishing position, improving the fire extinguishing effect. The threaded seat drives the limit winding box to rotate, realizing the winding and unwinding of the traction cable. By unwinding the traction cable, the rotating tube automatically deflects to a horizontal position under its own weight. The fire extinguishing dry powder is then delivered into the rotating tube and evenly distributed to the fire extinguishing area through the distribution holes. Combined with the rotation of the rotating tube, the fire extinguishing dry powder is sprayed to the fire extinguishing position in a circumferential distribution, so that the fire extinguishing dry powder can surround the fire position in a cylindrical shape, improving the use effect of the fire extinguishing dry powder, expanding the actual fire extinguishing isolation area, realizing rapid isolation of the fire area, preventing the fire from spreading and reducing losses. The threaded seat drives the limit winding box to rotate in the opposite direction, winding up the traction cable and rotating the tube to a vertical position, making it easy to store it in the sleeve and reducing space occupation.

[0015] 2. The fire hose is easily wound and stored using a roller. The connecting shafts at both ends of the roller drive the torsion springs to store energy, facilitating the winding of the fire hose. The connecting shafts also drive the rotating gear disc to rotate. The positioning of the support plate restricts the rotation of the gear disc, preventing the roller from rotating back and ensuring the stability of the fire hose during traction. By energizing the electromagnet in the inner gear ring, the magnetic attraction causes the support plate to deflect, releasing the rotation restriction of the gear disc. With the help of the magnetic block, the magnetic repulsion drives the gear disc to rotate actively. This, combined with the torsion force of the torsion spring, facilitates the rotation of the roller, enabling the orderly unwinding and winding of the fire hose and preventing the fire hose from becoming scattered and affecting its use.

[0016] 3. The cotton block is squeezed by the protrusions on the side of the drive slider. The cotton block transmits pressure to the reservoir, causing the viscous lubricant to be squeezed out through the fine holes. The viscous lubricant passes through the extrusion groove and comes into contact with the drive slider, thus lubricating the drive slider and ensuring its smooth sliding. This prevents jamming and avoids affecting the fire extinguishing response speed. By placing the reservoir and cotton block in the panel and connecting it to the side box, the panel and side box can be quickly disassembled and connected, making it easy to remove and replace the reservoir and cotton block in the panel. This makes it easier to replenish the viscous lubricant. In addition, there are multiple sets of panels, reservoirs, and cotton blocks, which can provide lubrication for the drive slider for a long time. Attached Figure Description

[0032] Example: Please refer to Figure 1-10The present invention provides the following technical solution: an unattended indoor fire-fighting robot, including a longitudinal electric slide rail 1, a guide rail 2 arranged parallel to each other on the longitudinal electric slide rail 1, a transverse electric slide rail 3 vertically connected to the top of the longitudinal electric slide rail 1 and the guide rail 2, the same end of the longitudinal electric slide rail 1 and the guide rail 2 being connected to a fixed frame 4, and a mounting plate 5 connected to the bottom sliding end of the transverse electric slide rail 3. The longitudinal electric slide rail 1, the guide rail 2 and the fixed frame 4 are all installed on the indoor ceiling according to the indoor layout, and the longitudinal electric slide rail 1 and the transverse electric slide rail 3 are both screw slide rails, driven by a drive motor, which facilitates the movement of the mounting plate 5 and the fire monitoring components and fire extinguishing components on it along the indoor ceiling area, so that the fire monitoring components and fire extinguishing components can reach the fire source in a timely and accurate manner, and the movement process is not obstructed by spatial obstructions, ensuring that the fire is detected and extinguished in a timely manner. A storage box 6 for winding and storing fire water pipes 7 is provided on one side of the fixed frame 4, and the fire water pipes 7 pass through the storage box 6. A pressure box 8 is connected to the top side of the mounting plate 5 via a support box 13. A fire extinguishing nozzle 9 is connected to the discharge end of one side of the pressure box 8. A monitoring box 10 is installed on the other side of the top of the mounting plate 5. A monitoring instrument 11 for fire monitoring is installed at the bottom of the monitoring box 10. The monitoring instrument 11 specifically includes a visible light camera, an infrared thermal imager, and a smoke alarm. The visible light camera, infrared thermal imager, and smoke alarm are all connected to the central controller inside the monitoring box 10 for communication. This facilitates timely detection of fires and rapid response to fire extinguishing. When a fire occurs, the visible light camera, infrared thermal imager, and smoke alarm upload data to the central controller. The coordinates of the fire point are estimated using a positioning algorithm. The central controller moves the fire extinguishing components directly above the fire point using the longitudinal electric slide rail 1 and the transverse electric slide rail 3, thus activating the fire extinguishing mechanism.

[0033] A rotary motor 14 is installed inside the support box 13. The bottom transmission end of the rotary motor 14 is connected to a sleeve 12. A drive motor 15 is embedded in the top of the inner side of the sleeve 12. The bottom transmission end of the drive motor 15 is connected to a threaded cylinder 16. A threaded seat 17 is connected to the threaded cylinder 16. A support rod 18 is fixed to the bottom end of the threaded seat 17. A sliding square plate 19 that fits and slides along the inner wall of the sleeve 12 is connected to the bottom of the support rod 18. A rotating tube 21 is rotatably connected to one side of the bottom of the support rod 18 via a rotating seat 20. A limiting seat is provided at the bottom of the threaded cylinder 16 to limit the movement of the threaded seat 17. When the threaded seat 17 contacts the limiting seat, the rotating tube 21 deflects to a horizontal position under its own weight. After the support rod 18 is fully retracted into the threaded cylinder 16, the rotating tube 21 rotates to a vertical position under the traction of the traction cable 24, facilitating the deflection and retraction of the rotating tube 21. Distributed holes 23 are evenly distributed at the bottom of the rotating tube 21. A through groove 22 is provided on the side of the sleeve 12 corresponding to the rotation path of the rotating tube 21. A traction cable 24 is tied to one end of the rotating tube 21, and the other end of the traction cable 24 is limited and wound within the limiting winding box 25 at the top of the threaded cylinder 16. A slot is opened on the side of the sliding square plate 19 corresponding to the rotating tube 21. The threaded cylinder 16 drives the limiting winding box 25... 5. The limit winding box 25 is rotated synchronously. A guide groove is provided on one side for the traction cable 24 to pass through, so that the limit winding box 25 can drive the traction cable 24 to wind and unwind. A connecting hose 26 is connected to the inlet end of the rotating pipe 21. The connecting hose 26 passes through the bottom of the sleeve box 12 and is connected to the conveying box 27 fixed to the side of the sleeve box 12. The fire water pipe 7 is connected to the booster pump inside the booster box 8, and the output end of the booster pump is connected to the fire extinguishing nozzle 9 through a steel pipe. The conveying box 27 delivers fire extinguishing dry powder to the connecting hose 26 in the form of gas-solid two-phase flow through the high-pressure gas cylinder inside. The high-pressure gas cylinder is filled with high-pressure inert gas, which is nitrogen. Both the fire water pipe 7 and the connecting hose 26 are flexible metal braided hoses. The tensile strength of the fire water pipe 7 and the connecting hose 26 is considered.

[0034] A guide ring 28 is connected to the top side of the horizontal electric slide rail 3 to guide the fire water pipe 7. A roller 29 is installed inside the storage box 6 to wind and store the fire water pipe 7. The bottom of the guide ring 28 is connected to the top of the horizontal electric slide rail 3 through a universal ball joint. One end of the fire water pipe 7 enters the storage box 6 and is wound on the roller 29. The other end of the fire water pipe 7 passes out of the storage box 6 and is connected to the fire hydrant water pipe. This facilitates the guide ring 28 to guide the position of the fire water pipe 7 and allows the guide ring 28 to rotate flexibly. End boxes 30 are installed on both sides of the inner side wall of the storage box 6. The two ends of the roller 29 are rotatably connected to the storage box 6 through a connecting shaft 31. A torsion spring 33 is sleeved on the outer side of the extension end of the connecting shaft 31. An end cap 32 is provided on the outer side of the storage box 6 at the position outside the torsion spring 33. A rotating gear disk 34 is connected to the connecting shaft 31 at a position inside the end box 30. Magnets 35 are mounted on the helical teeth of the rotating gear disk 34. An internal gear ring 36 is installed on the inner wall of the end box 30. Electromagnets 37 are mounted on the helical teeth of the internal gear ring 36 corresponding to the positions of the magnets 35. A support plate 38 is rotatably connected to the inner side of the end box 30 to limit and support the rotating gear disk 34. When the connecting shaft 31 rotates, it drives the torsion spring 33 on its outer side to rotate, and the connecting shaft 31 synchronously drives the rotating gear disk 34 to rotate inside the end box 30. The support plate 38, in a naturally suspended state, resists and limits the helical teeth of the rotating gear disk 34. The torsion spring 33 is driven to rotate by the connecting shaft 31 at both ends of the roller 29, facilitating energy storage for use in the fire water pipe 7. During rapid winding, the rotation direction of the rotating toothed disk 34 is restricted by the positioning of the support plate 38, preventing the automatic rotation of the winding roller 29. An adsorption block 39 is provided on the edge of the support plate 38 corresponding to the electromagnet 37. When the electromagnet 37 is energized, the magnetic repulsion drives the magnetic block 35 and the rotating toothed disk 34 to deflect, attracting the adsorption block 39 and releasing its restriction on the rotating toothed disk 34. When the electromagnet 37 is energized, the magnetic attraction drives the support plate 38 to deflect, releasing the rotation restriction of the rotating toothed disk 34. The magnetic repulsion then drives the rotating toothed disk 34 to rotate, forming a combined force with the torsional force of the torsion spring 33, facilitating the rotation of the winding roller 29.

[0035] The top of the longitudinal electric slide rail 1 and the guide rail 2 is provided with a rubber sheet 40, and the longitudinal electric slide rail 1 and the guide rail 2 drive the transverse electric slide rail 3 to move through the internal active drive slider 41. The sides of the longitudinal electric slide rail 1 and the guide rail 2 are provided with side boxes 42, and the side boxes 42 are embedded with detachable inserts 43. The rubber sheet 40 is provided at the top two ends of the longitudinal electric slide rail 1 and the guide rail 2. The side boxes 42 are provided with grooves, and the inserts 43 are tightly embedded in the grooves. The contact position between the inserts 43 and the grooves is provided with anti-slip pieces. The rubber sheet 40 can protect the top of the longitudinal electric slide rail 1 and the guide rail 2 and facilitate quick and detachable connection between the inserts 43 and the side boxes 42. A liquid reservoir 44 is embedded and connected to the inner side of the panel 43. A cotton block 45 is provided at the extrusion end position on one side of the liquid reservoir 44 on the edge of the panel 43. Extrusion grooves 46 are evenly arranged in the cotton block 45. Protrusions 47 are provided on both sides of the drive slider 41. The liquid reservoir 44 is filled with viscous lubricating fluid, and fine holes are evenly arranged on the side of the liquid reservoir 44 near the cotton block 45. The extrusion grooves 46 penetrate the interior of the cotton block 45. When the drive slider 41 slides, the protrusions 47 on both sides of the drive slider 41 squeeze the cotton block 45, which facilitates the contact of the viscous lubricating fluid with the drive slider 41, so as to achieve lubrication during the active driving process of the drive slider 41 and ensure its sliding flexibility.

[0036] The working principle and usage process of this invention are as follows: During fire monitoring, the longitudinal electric slide rail 1, guide rail 2, and transverse electric slide rail 3 are respectively installed on the indoor ceiling through the fixing frame 4. The longitudinal electric slide rail 1, guide rail 2, and transverse electric slide rail 3 form a multi-directional motion mechanism, which drives the mounting plate 5 and the fire monitoring component and fire extinguishing component on it to move along the indoor ceiling area. This enables the fire monitoring component to monitor the indoor space without blind spots. When the fire monitoring component detects a fire, the monitoring data is transmitted to the central controller. The central controller estimates the coordinates of the fire point through a positioning algorithm, plans the optimal path, and drives the longitudinal electric slide rail 1 and transverse electric slide rail 3 to move the fire extinguishing component directly above the fire point. At the same time, the fire extinguishing component is activated to extinguish the fire. During the fire extinguishing process, the rotary motor 14 first drives the sleeve 12 to rotate, and the drive motor 15 drives the threaded cylinder 16 to rotate, which facilitates the lifting and lowering of the threaded seat 17, support rod 18, sliding square plate 19 and rotating seat 20. The height of the rotating tube 21 is adjusted so that the rotating tube 21 reaches the fire extinguishing position. The threaded seat 17 synchronously drives the limit winding box 25 to rotate, and the traction cable 24 is wound up and unwound. When the rotating pipe 21 is lowered for fire extinguishing, the traction cable 24 is unwound, causing the rotating pipe 21 to automatically deflect to a horizontal position under its own weight. The fire extinguishing dry powder is then transported into the rotating pipe 21 through the connecting hose 26 and the delivery box 27, so that the fire extinguishing dry powder is evenly distributed to the fire extinguishing area through the distribution hole 23. At the same time, the rotating pipe 21 is rotated by the sleeve 12, so that during the fire extinguishing process, the fire extinguishing dry powder is sprayed to the fire extinguishing position in a circumferential distribution through the rotation of the rotating pipe 21. This allows the fire extinguishing dry powder to surround the fire position in a cylindrical shape, improving the use effect of the fire extinguishing dry powder, expanding the actual fire extinguishing isolation area, and achieving rapid isolation of the fire area. This can prevent the fire from continuing to spread and reduce losses at the first moment of the fire. Simultaneously, the fire extinguishing components drive the fire hose 7 to move synchronously, and the booster box 8 and fire extinguishing nozzle 9 are used to further extinguish the fire. When the fire hose 7 is stretched and moved, the roller 29 in the storage box 6 winds and stores the fire hose 7, making it convenient for the fire hose 7 to follow the fire extinguishing components to move. The guide ring 28 guides the position of the fire hose 7. When the fire hose 7 is stretched, the connecting shafts 31 at both ends of the roller 29 drive the torsion spring 33 to store energy, so that the fire hose 7 can be quickly wound up when it retracts. When the roller 29 rotates, the connecting shafts 31 drive the rotating toothed disc 34 to rotate. When the fire hose 7 is used for traction, the position of the support plate 38 restricts the rotation direction of the rotating toothed disc 34 to prevent the roller 29 from rotating automatically. When the drive slider 41 slides automatically along the longitudinal electric slide rail 1 and guide rail 2, the rubber sheet 40 shields and protects the top of the longitudinal electric slide rail 1 and guide rail 2 to prevent debris from falling in. When the drive slider 41 slides, the protrusion 47 on its side squeezes the cotton block 45, so that the cotton block 45 transmits pressure to the reservoir 44. Under the squeezing action, the viscous lubricating liquid in the reservoir 44 is squeezed out through the fine holes on its side, so that the viscous lubricating liquid passes through the evenly distributed extrusion grooves 46 in the cotton block 45, and finally the viscous lubricating liquid comes into contact with the drive slider 41, so as to achieve lubrication treatment during its active driving process. After the fire is extinguished, the threaded seat 17 drives the limit winding box 25 to rotate in the opposite direction, thereby winding up the traction cable 24. After the fire is extinguished, the rotating tube 21 is rotated to a vertical position, making it easy to store it in the sleeve box 12 and reducing space occupation. When the winding roller 29 winds up the fire water pipe 7, the electromagnet 37 in the inner toothed ring 36 is energized. First, the magnetic attraction drives the support plate 38 to deflect, releasing the rotation restriction of the support plate 38 on the rotating toothed disc 34. At the same time, in conjunction with the magnetic block 35, the magnetic repulsion drives the rotating toothed disc 34 to rotate actively. This, together with the torsional force of the torsion spring 33, forms a resultant force, which facilitates the rotation of the winding roller 29, realizing the orderly unwinding and winding of the fire water pipe 7 and preventing the fire water pipe 7 from being scattered and affecting its use. When viscous lubricant needs to be replenished, a side box 42 is provided on the side of the longitudinal electric slide rail 1 and the guide rail 2, and the reservoir 44 and cotton block 45 are placed in the panel 43. The quick and detachable connection between the panel 43 and the side box 42 makes it easy to remove the panel 43 so that the reservoir 44 and cotton block 45 can be taken out and replaced. This makes it more convenient to replenish the viscous lubricant.
