Description

Technical Field

[0001] The present invention relates to the technical field of fire fighting equipment, and in particular to a high altitude fire fighting extinguishing device and a fire fighting method. Background Art

[0002] Fire in high-rise buildings is an extremely serious problem. It not only poses a serious threat to the safety of people's lives, but also causes huge property losses. The difficulties faced in extinguishing high-rise fires are multifaceted. These difficulties not only test the emergency response capabilities of the fire department, but also put forward higher requirements for firefighting technical equipment. Through continuous reform and innovation of firefighting equipment, the firefighting effect of high-rise building fires can be effectively increased, and the dangers faced by firefighters in firefighting work can be reduced.

[0003] In the prior art, a large number of fire-fighting devices for high-rise buildings are also disclosed. Among them, a Chinese patent with publication number CN110075446A discloses a fire-fighting robot for buildings, including a casing, a rocker mechanism, a climbing mechanism, and a water spraying mechanism. The casing is provided with a rocker mechanism, the climbing mechanism is connected to the rocker mechanism, and the climbing mechanism is connected to the water spraying mechanism; the casing is composed of a bracket, a guard plate, a shaft rod, a reinforcing rib, a buffer sheet, a latch, and a lock hole. The side of the bracket is provided with a reinforcing rib, the buffer sheet is provided on the bottom surface of the bracket, and the latch is provided at one end of the bottom position of the bracket and is engaged with the lock hole provided on the other side of the bracket.

[0004] When in use, the robot's casing is opened and it is mounted on the outer wall pipe closest to the building on fire. The opening of the keyhole corresponds to the bolt inside the latch to lock the two, and the ports of the fire water pipe and the water spray pipe are connected. The track wheels are controlled to rotate to drive the angled propulsion belt upward. When the robot moves to the outer wall of the building on fire, the suction cup is used to attach the robot to the pipe. At this time, high-pressure water is delivered to the connected port, and the water spray mechanism sprays high-speed and high-pressure water to extinguish the fire.

[0005] However, in the process of extinguishing fires in high-rise buildings using the above-mentioned prior art, there are still the following shortcomings: 1. In the process of extinguishing a high-rise building fire, when there is no pipe on the outer wall of the building where the fire occurs or the pipe is not near the fire site, the robot cannot climb to the high-rise area of ​​the fire scene, and thus cannot complete the fire extinguishing work, which has strong limitations.

In terms of technical effect, it can block the large amount of smoke generated when a fire occurs in a high-rise building and at the same time can play a certain role in extinguishing the fire, thereby preventing the smoke from affecting the sight of firefighters, thereby ensuring that firefighters can perform reasonable firefighting work according to the fire situation, especially when firefighters are preparing to enter the building from the position of the present invention to perform fire-fighting work, the smoke prevention unit 5 can provide firefighters with a relatively safe entry environment, effectively ensuring the personal safety of firefighters.

[0037] Embodiment 1:

[0038] Reference Figure 1As shown, in order to realize efficient and rapid fire extinguishing in a high-rise building where a fire occurs, specifically, this embodiment provides a high-altitude fire extinguishing device, including a main body box 1, a fire interface 2 is installed on one side of the main body box 1 along its length direction, a square groove 3 is opened inside the main body box 1, a moving unit 4 is installed inside the square groove 3, a smoke prevention unit 5 is arranged outside the main body box 1, the moving unit 4 includes a power component 41 arranged on the bottom wall of the square groove 3, and a travel component 42 is installed on both side walls of the main body box 1 in the width direction.

[0039] Furthermore, in this embodiment, the fixing unit 6 includes a drilling assembly 61 and a limiting assembly 63 arranged at two corners of the square groove 3 away from the fire interface; the smoke prevention unit 5 includes a square sprinkler pipe 51 installed on the outside of the main box 1.

[0040] In actual application, firefighters first need to connect the fire hose to the fire interface, and then place the device on the outer wall of the building where the fire occurs and make the device fit with the outer wall of the building. The power component 41 and the travel component 42 cooperate with each other to control the device to move along the outer wall of the building toward the location where the fire occurs. When the device moves to the fire, the drilling component 61 and the limit component 63 cooperate with each other to fix the device on the outer wall of the building, so as to avoid the device falling during the fire extinguishing process, thereby ensuring that the device can smoothly extinguish the fire. After the device is fixed on the outer wall of the building, the smoke generated by the fire can be effectively suppressed by the smoke prevention unit 5, so as to avoid the smoke affecting the firefighters' observation of the fire scene and increase the fire extinguishing efficiency of the firefighters.

[0041] Reference Figure 2 and Figure 3 As shown, in order to provide power to the device so that the device can successfully complete the fire extinguishing work, based on this, in this embodiment, the power component 41 includes a bidirectional motor 411 arranged on the inner bottom wall of the square groove 3 through a mounting block, and transmission shafts 412 are arranged at both ends of the output shaft of the bidirectional motor 411. The transmission shaft 412 rotates through the main box 1 away from the end of the bidirectional motor 411 and extends to the outside of the main box 1. The two side walls of the square groove 3 along its width direction are rotated and penetrated with a linkage shaft 413 located on the side away from the bidirectional motor 411. The two ends of the linkage shaft 413 extend to the outside after passing through the main box 1; the power component 41 also includes a controller 414 arranged on the inner bottom wall of the square groove 3 and located between the transmission shaft 412 and the linkage shaft 413. The outer walls of the transmission shaft 412 and the linkage shaft 413 are both sleeved with power pulleys 415 located on either side of the bidirectional motor 411, and the outer walls of the two power pulleys 415 are jointly sleeved with a transmission belt 416 for providing power to the device; the bidirectional motor 411 and the controller 414 are electrically connected.

[0042] In addition, the controller 414 used in this embodiment is a PLC controller 414 in the prior art, which is mainly used to control the start and stop of the bidirectional motor 5. The working principle of the controller 414 will not be described here.

[0043] Furthermore, in this embodiment, the traveling component 42 includes a connecting pulley 421 sleeved on both ends of the transmission shaft 412 and the linkage shaft 413, the outer walls of the two connecting pulleys 421 on the same side are jointly sleeved with a moving belt 422, the outer wall of the moving belt 422 is provided with a plurality of equally distributed connecting holes 423, the outer wall of the moving belt 422 is provided with a plurality of adsorption cylinders 424 corresponding to the connecting holes 423, the inner diameter of the adsorption cylinder 424 gradually expands away from the moving belt 422, an annular groove 425 is provided at the end of the adsorption cylinder 424 away from the moving belt 422, a suction cup 426 is slidably installed on the inner wall of the adsorption cylinder 424, the inclined surface where the suction cup 426 contacts the inner wall of the adsorption cylinder 424 is provided with an annular block 427 located in the annular groove 425, the annular block 427 is in sliding contact with the annular groove 425, and an annular protrusion 428 for limiting the annular block 427 is installed at one end of the annular groove 425.

[0044] Furthermore, as in the present embodiment, a vacuum box 429 is arranged between the two connecting pulleys 421 on the same side, the lower end of the vacuum box 429 is in sliding contact with the moving belt 422, and a square hole 430 connected to the connecting hole 423 is opened at the lower end of the vacuum box 429, a vacuum tube 431 is installed on the side of the vacuum box 429 close to the main box 1, a vacuum pump 432 is arranged on the bottom wall of the square groove 3 through the base, the vacuum tube 431 is connected to the vacuum pump 432, and the vacuum pump 432 is electrically connected to the controller 414.

[0045] In actual application, first, the bidirectional motor 411 is controlled by the controller 414 to be powered on and started, the output shaft of the bidirectional motor 411 drives the transmission shaft 412 to rotate, the transmission shaft 412 drives the linkage shaft 413 to rotate synchronously through the transmission belt 416, the transmission shaft 412 and the linkage shaft 413 drive the moving belt 422 to rotate through the connecting pulley 421, and the moving belt 422 drives the adsorption cylinder 424 to rotate along the contour of the moving belt 422; then, the vacuum pump 432 is controlled by the controller 414 to be powered on and started, the vacuum pump 432 extracts the air in the vacuum tube 431 and the vacuum box 429, so that the suction cup 426 generates negative pressure, the suction cup 426 is made of high temperature resistant and flame retardant materials, and generates negative pressure through the vacuum pump 432 to achieve strong adsorption, which is suitable for a variety of exterior wall materials such as smooth glass and rough concrete. Under high temperature fire conditions, the adsorption performance remains stable, ensuring the safe movement of the device on the outer wall, so that the moving belt 422 drives the adsorption cylinder 424 to move circumferentially while cooperating with the suction cup 426 to drive the main box 1 to move to a higher place in the building. When the suction cup 426 generates suction on the outer wall of the building, the suction cup 426 can move toward the side close to the main box 1 under the suction of the vacuum pump 432, thereby achieving a close fit between the adsorption cylinder 424 and the outer wall of the building, reducing the influence of gravity on the device, avoiding the possibility of the device falling downward due to gravity during the movement and fixation process, and increasing or decreasing the climbing effect of the device.

[0046] When the moving belt 422 drives the adsorption cylinder 424 to rotate to the side close to the outer wall of the building, the connecting hole 423 connected to the adsorption cylinder 424 is gradually connected to the square hole 430, and the suction cup 426 generates suction on the outer wall of the building under the action of the vacuum pump 432, so that the device can be tightly adsorbed on the outer wall of the building, thereby achieving the purpose of moving the device on the outer wall of the building. At the same time, the adsorption cylinder 424 on the opposite side of the moving direction of the device and the connecting hole 423 connected to the adsorption cylinder 424 are gradually separated from the square hole 430, so that the adsorption cylinder 424 can be effectively separated from the outer wall of the building during the process of moving the device toward the fire. Through the above steps, the device can be effectively and quickly moved toward the fire, ensuring that the device can quickly reach the location of the fire, increasing the reliability and maneuverability of the device.

[0047] It should be noted that when the adsorption cylinder 424 is adsorbed on the outer wall of the building through the suction cup 426, the suction cup 426 shrinks into the adsorption cylinder 424 under the continuous action of negative pressure, so that the adsorption cylinder 424 forms a hard contact with the outer wall of the building through the annular block 427, thereby ensuring the stability of the device during the movement along the outer wall of the building, and avoiding the shaking or lack of stability of the device during the movement due to the easy deformation characteristics of the flexible material of the suction cup 426; in addition, the suction cup 426 used in this embodiment is made of high temperature resistant and flame retardant material, so when the device is adsorbed on the outer wall of the building through the suction cup 426, the suction cup 426 can work normally in a high temperature environment and will not burn, thereby ensuring the adsorption performance and the stability of the device during operation.

[0048] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, in order to increase the stability of the device and prevent the device from falling during the fire extinguishing process, based on this, in the present embodiment, the drilling assembly 61 includes a second motor 611 which is arranged on the inner bottom wall of the square slot 3 through a mounting frame and is located on the side of the square slot 3 away from the fire interface 2. The second motor 611 is electrically connected to the controller 414. Both ends of the output shaft of the second motor 611 are installed with matching shafts 612. The outer wall of the matching shaft 612 is away from the second motor 611. A linkage bevel gear 613 is sleeved on the side; the two corners of the inner bottom wall of the square slot 3 away from the fire interface 2 are provided with fixing holes 614, and the fixing holes 614 are provided with a plurality of fixing holes 614. A fixed drill bit 615 is slidably installed on the wall, a threaded rod 616 is provided on the upper end of the fixed drill bit 615, a nut sleeve 617 is rotatably sleeved on the outer wall of the threaded rod 616 through a connecting block 618, the connecting block 618 is installed on the side wall of the square groove 3 at one end away from the threaded rod 616, a square block 619 is provided at the lower end of the connecting block 618, a fixed block 620 parallel to the connecting block 618 is installed at the lower end of the square block 619, a limiting ring 621 is rotatably sleeved on the outer wall of the fixed drill bit 615, and the fixing block 620 is located on the side of the fixing block 620 away from the square block 619, and a matching bevel gear 622 is sleeved on the outer wall of the threaded rod 616 and located between the limiting ring 621 and the nut sleeve 617.

[0050] It should be noted that the downward pressure spring rod 627 always applies downward pressure to the circular block 626 in the direction of the outer wall of the building, thereby applying the downward pressure required for drilling to the threaded rod 616 and the fixed drill bit 615, thereby increasing the drilling effect of the device; through the mutual cooperation of the limit groove 623 and the limit block 624, the matching bevel gear 622 can be limited, so that the matching bevel gear 622 will not move up and down with the threaded rod 616 while driving the threaded rod 616 to rotate, ensuring that the device can be smoothly fixed on the outer wall of the building.

[0051] Furthermore, in this embodiment, the limiting assembly 63 includes an inclined bevel gear 631 which is sleeved on the outer wall of the matching shaft 612 and is located on the side of the linkage bevel gear 613 close to the second motor 611, a raised strip 632 which is parallel to the axis of the matching shaft 612 is installed on the inner top wall of the square groove 3, a contact plate 633 which is located on the inner top wall of the square groove 3 and is located on the side of the raised strip 632 close to the second motor 611, a spacer block 634 which is located on the inner top wall of the square groove 3 and is located on the side of the raised strip 632 away from the contact plate 633, an initial spring rod 635 is installed on the side of the contact plate 633 away from the second motor 611, a contact plate 636 is provided on the end of the initial spring rod 635 away from the contact plate 633, and the spacer block 634 is away from the contact plate A hollow spring rod 637 is provided on one side of the contact plate 633, and a limiting protrusion 638 is installed at one end of the hollow spring rod 637 away from the spacer block 634; an inclined bevel gear rack 639 located between the contact plate 633 and the spacer block 634 is provided on the side of the raised strip 632 away from the inner top wall of the square groove 3, and an elastic pull rope 640 is installed on the end of the limiting protrusion 638 close to the spacer block 634, and the end of the elastic pull rope 640 away from the limiting protrusion 638 passes through the hollow spring rod 637 and the spacer block 634 and is connected to the inclined bevel gear rack 639, and a sliding groove for being mounted on the outer wall of the raised strip 632 is provided on the end of the inclined bevel gear rack 639 close to the raised strip 632, and the raised strip 632 is in sliding contact with the inclined bevel gear 631.

[0052] It should be further explained that the initial spring rod 635 always applies a thrust to the inclined bevel rack 639 away from the second motor 611, which can provide the inclined bevel gear 631 with the initial power required for the inclined bevel gear 631 to move away from the second motor 611, ensuring that the limiting protrusion 638 can smoothly release the limit on the circular block 626; the hollow spring rod 637 always applies a resistance force to the limiting protrusion 638 away from the second motor 611, thereby ensuring that the device is released through the threaded rod during the process of fixing. When 616 drives the circular block 626 to move away from the outer wall of the building to reset, the limiting protrusion 638 can limit the circular block 626 again; in addition, the inclined bevel gear 631 and the inclined bevel rack 639 meshing therewith can drive the inclined bevel rack 639 to move through mutual cooperation. When the inclined bevel rack 639 drives the limiting protrusion 638 to move to the side away from the circular block 626, the limiting effect of the limiting protrusion 638 on the circular block 626 can be released. Conversely, the limiting protrusion 638 can be controlled to reset and move.

[0053] In actual application, when the device reaches the outer wall of the building on the floor where the fire is located, the controller 414 controls the second motor 611 to start by connecting the power, and the output shaft of the second motor 611 drives the matching shaft 612 to rotate, and the matching shaft 612 drives the linkage bevel gear 613 and the inclined bevel gear 631 to rotate synchronously, and the inclined bevel gear 631 drives the inclined bevel rack 639 meshing therewith to move toward the side of the second motor 611, and the inclined bevel rack 639 overcomes the elasticity of the hollow spring rod 637 through the elastic pull rope 640 and drives the limiting protrusion 638 to move synchronously toward the side of the second motor 611, so as to release the limiting protrusion 638 from the circular block The limit of 626 allows the circular block 626 to drive the threaded rod 616 and the fixed drill bit 615 to move toward one side of the building's outer wall under the action of the downward pressure spring rod 627; at the same time, the linkage bevel gear 613 drives the mating bevel gear 622 meshing with it to rotate, and the mating bevel gear 622 drives the threaded rod 616 to rotate synchronously, and the threaded rod 616 drives the fixed drill bit 615 to rotate, so that the fixed drill bit 615 moves and rotates and drills into the building's outer wall. By fixing the fixed drill bit 615 on the building's outer wall, the device can have sufficient bearing capacity, so that water can be supplied to the smoke prevention unit 5 through the fire interface 2 later for fire extinguishing and smoke prevention.

[0054] When the fixed drill bit 615 is drilling holes in the exterior wall of the building, the mutual cooperation between the threaded rod 616 and the nut sleeve 617 can further apply downward pressure to the threaded rod 616 and the fixed drill bit 615 in the direction of the exterior wall of the building, further increasing the drilling efficiency of the device and reducing the fixing time of the device.

[0055] After completing the fire extinguishing work, the second motor 611 rotates in the opposite direction, and the fixed drill bit 615 is pulled out from the outer wall of the building and reset through the cooperation of the threaded rod 616 and the nut sleeve 617. During this period, the upper end of the circular block 626 gradually contacts the inclined surface of the lower end of the limiting protrusion 638 and applies an extrusion force to the limiting protrusion 638. The limiting protrusion 638 adaptively gives way under the extrusion pressure of the circular block 626. When the circular block 626 moves upward to the highest point, the limiting protrusion 638 rebounds under the action of the hollow spring rod 637 and limits the circular block 626 again to facilitate the recovery of the device.

[0056] Reference Figure 2 As shown, in order to prevent the smoke from spreading outward and causing other adverse effects, based on this, in the present embodiment, the smoke prevention unit 5 also includes a plurality of mist nozzles 52 equidistantly arranged at the four corners of the square sprinkler pipe 51 away from the side of the main box 1 and the side close to the main box 1, and an auxiliary sprinkler pipe 53 is arranged on both sides of the inner bottom wall of the square groove 3 along its length, and a plurality of mist nozzles 52 equidistantly distributed and connected to the auxiliary sprinkler pipe 53 are installed on the side wall of the main box 1, and the auxiliary sprinkler pipe 53 is connected to the square sprinkler pipe 51 at one end close to the fire interface.

[0057] In actual application, when the device reaches the designated position and is fixed, firefighters provide firefighting water to the device through a firefighting water pipe connected to the firefighting interface 2. The firefighting water is sprayed out through the mist nozzle 52 during the process of passing through the square sprinkler pipe 51 and the auxiliary sprinkler pipe 53. The sprayed firefighting water forms a mist that diffuses around the device under the action of high pressure. The smoke and flame fragments generated by the fire can be intercepted by the sprayed water curtain to avoid the adverse effects caused by the spread of smoke and prevent the flame fragments from causing fire again, thereby facilitating the firefighters to enter the scene for rescue and reduce losses.

[0058] Embodiment 2:

[0059] Reference Fig.10 and Fig.11 As shown, on the basis of Example 1, in order to make the adsorption cylinder 424 fit tightly with the outer wall of the building and avoid the small gap between the adsorption cylinder 424 and the outer wall of the building affecting the adsorption performance of the device, specifically, the traveling component 42 also includes a fitting part 433 arranged at the end of the adsorption cylinder 424 away from the moving belt 422, the fitting part 433 includes two support rings 434 arranged at the end of the adsorption cylinder 424 away from the moving belt 422, an annular airbag 435 is installed between the two support rings 434, and the annular airbag 435 extends from one end of the adsorption cylinder 424 away from the moving belt 422 to both sides close to the two support rings 434.

[0060] In actual application, when the suction cup 426 is adsorbed on the outer wall of the building under the action of the vacuum pump 432 and drives the adsorption cylinder 424 to move closer to the side of the outer wall of the building, the annular air bag 435 can fill the gap between the adsorption cylinder 424 and the outer wall of the building, thereby preventing the device from falling due to the large gap between the adsorption cylinder 424 and the outer wall of the building affecting the stability after adsorption, thereby increasing the climbing effect of the device.

[0061] In addition, the present invention also provides a high-altitude fire extinguishing method, comprising the following steps: S1. Preparation before work: Connect the fire hose to the fire interface, and then fit the device to the exterior wall of the building.

[0063] When the moving belt 422 drives the adsorption cylinder 424 to rotate to the side close to the outer wall of the building, the connecting hole 423 connected to the adsorption cylinder 424 is gradually connected to the square hole 430, and the suction cup 426 generates suction on the outer wall of the building under the action of the vacuum pump 432, so that the device can be tightly adsorbed on the outer wall of the building, thereby achieving the purpose of moving the device on the outer wall of the building. At the same time, the adsorption cylinder 424 on the opposite side of the moving direction of the device and the connecting hole 423 connected to the adsorption cylinder 424 are gradually separated from the square hole 430, so that the adsorption cylinder 424 can be effectively separated from the outer wall of the building during the process of moving the device toward the fire.

[0064] S3, fixing device: When the device reaches the outer wall of the building on the floor where the fire is located, the controller 414 controls the second motor 611 to start by connecting the power, and the output shaft of the second motor 611 drives the matching shaft 612 to rotate, and the matching shaft 612 drives the linkage bevel gear 613 and the inclined bevel gear 631 to rotate synchronously, and the inclined bevel gear 631 drives the inclined bevel rack 639 meshing therewith to move toward the side of the second motor 611, and the inclined bevel rack 639 overcomes the elasticity of the hollow spring rod 637 through the elastic pull rope 640 and drives the limiting protrusion 638 to move synchronously toward the side of the second motor 611, so as to release the limiting protrusion 638 from the circular The limiting position of block 626 allows the circular block 626 to drive the threaded rod 616 and the fixed drill bit 615 to move toward one side of the building's outer wall under the action of the downward pressure spring rod 627; at the same time, the linkage bevel gear 613 drives the mating bevel gear 622 meshing therewith to rotate, and the mating bevel gear 622 drives the threaded rod 616 to rotate synchronously, and the threaded rod 616 drives the fixed drill bit 615 to rotate, so that the fixed drill bit 615 moves and rotates and drills into the building's outer wall. By fixing the fixed drill bit 615 on the building's outer wall, the device can have sufficient bearing capacity, so that water can be supplied to the smoke prevention unit 5 through the fire interface 2 later for fire extinguishing and smoke prevention.

[0065] When the fixed drill bit 615 is drilling holes in the building's exterior wall, the threaded rod 616 and the nut sleeve 617 cooperate with each other to further apply downward pressure to the threaded rod 616 and the fixed drill bit 615 in the direction of the building's exterior wall, further increasing the drilling speed of the device.

[0066] S4. Implement fire extinguishing: When the device reaches the designated position and is fixed, the firefighters provide the device with fire water through the fire hose connected to the fire interface 2. The fire water is sprayed out through the mist nozzle 52 during the process of passing through the square sprinkler pipe 51 and the auxiliary sprinkler pipe 53. The sprayed fire water forms a mist that spreads around the device under high pressure. The smoke and flame fragments generated by the fire can be intercepted by the sprayed water curtain.

During this period, the upper end of the circular block 626 gradually contacts the inclined surface of the lower end of the limiting protrusion 638 and applies an extrusion force to the limiting protrusion 638. The limiting protrusion 638 adaptively gives way under the extrusion pressure of the circular block 626. When the circular block 626 moves upward to the highest point, the limiting protrusion 638 rebounds under the action of the hollow spring rod 637 and limits the circular block 626 again to facilitate the recovery of the device.
