Description

Technical Field

[0001] This invention belongs to the field of fire protection technology, specifically relating to a long-range diversion fire monitor, a fire protection method, and a method of using a long-range diversion fire monitor. Background Technology

[0002] The media used in the petrochemical industry are often flammable and explosive, leading to frequent fire accidents.

[0003] The petrochemical industry produces media with high calorific value and fast combustion speed, resulting in high heat release rate and surrounding heat radiation. Therefore, rescue devices need to extinguish fires from a safe distance, which requires fire monitors to have a long spray range.

[0004] Currently, the fire protection industry commonly uses flow-guided fire monitors, which have two working modes: direct jet and spray cooling. However, due to the obstruction and redirection of water flow by the structure of the flow guide plate, the direct jet suffers from significant resistance loss, resulting in a greatly shortened range. To increase the direct jet range, the diameter of the flow guide plate is usually reduced, but this leads to a poorer spray cooling effect.

[0005] Therefore, it is necessary to comprehensively consider the structure of the flow-guided fire monitor and develop a fire monitor that can simultaneously possess both direct current and spray functions, while also having good direct current range and spray effect. Summary of the Invention

[0006] In view of the technical problems mentioned above, the present invention aims to provide a long-range flow-guided fire monitor that can solve at least one of the above technical problems.

[0007] The present invention also proposes a firefighting method that uses a long-range deflector fire monitor provided according to the present invention, which can increase the range.

[0008] This invention also proposes a method for using a long-range diversion fire monitor, applying the long-range diversion fire monitor to petrochemical fires.

[0009] According to the present invention, a long-range flow-guided fire monitor is provided, comprising: an outer cylinder; and a flow-guided disk coaxially disposed within the outer cylinder, wherein an annular channel is formed between the outer wall of the flow-guided disk and the inner wall of the outer cylinder, allowing the medium to pass through; a conveying chamber is disposed inside the flow-guided disk, and an opening and closing member is disposed on the flow-guided disk; in a burst mode, the opening and closing member closes the conveying chamber, thereby allowing the medium to be ejected through the annular channel; in a direct flow mode, the opening and closing member opens the conveying chamber, thereby allowing the medium to be ejected through the conveying chamber.

[0010] In one specific embodiment, multiple opening and closing components are evenly arranged circumferentially at the rear end of the guide plate by means of hinges.

[0011] In one specific embodiment, the radially outer portion of the rear end of the guide plate is configured as an edge redirection section, and the central portion of the rear end of the guide plate is configured as a central redirection section. The first side of the opening and closing member is hinged to the edge redirection section. In the opening mode, the second side of the opening and closing member is close to the central redirection section, thereby closing the conveying cavity. In the direct current mode, the second side of the opening and closing member is moved away from the central redirection section, thereby opening the conveying cavity.

[0012] In one specific embodiment, in the opening mode, the rear side of the second side of the opening member abuts against the front side of the central redirection section.

[0013] In one specific embodiment, the opening and closing component is made of magnetic material, and the opening and closing component is controlled by magnetic force to perform the action, thereby enabling the long-range guide fire monitor to switch between bloom mode and DC mode.

[0014] In one specific embodiment, a switch controller capable of generating magnetic force is provided on the outer wall of the outer cylinder, and the magnetic force generated by the switch controller can control the opening and closing components to perform actions.

[0015] In one specific embodiment, the switch controller includes a fixture disposed on the outer cylinder and a coil wound around the outside of the fixture.

[0016] In one specific embodiment, the outer cylinder includes a support section and an expansion section coaxially and movably disposed on the support section. The expansion section and the guide plate are configured to form an annular channel. By moving the expansion section relative to the guide plate, the opening and closing of the annular channel can be controlled.

[0017] In one specific embodiment, the support segment is connected to the expansion segment via a telescopic mechanism, the telescopic mechanism comprising: a driver disposed on the support segment; and a telescopic rod, the driver being connected to the expansion segment via the telescopic rod, thereby driving the expansion segment to move coaxially relative to the support segment.

[0018] In one specific embodiment, the outer cylinder further includes a contraction section coaxially disposed at the rear end of the support section and a water inlet section coaxially disposed at the rear end of the contraction section.

[0019] In one specific embodiment, a rectifier is coaxially arranged in the water inlet section, and the rectifier is coaxially connected to the guide plate through a guide core.

[0020] In one specific embodiment, a connecting pipe is coaxially disposed at the front end of the guide plate, and the connecting pipe is in communication with the conveying cavity.

[0021] In one specific embodiment, the connecting pipe includes a contraction cylinder coaxially disposed at the front end of the guide plate and a nozzle coaxially disposed at the front end of the contraction cylinder.

[0022] According to the present invention, a fire-fighting method is also provided, which uses a long-range diverting fire monitor proposed according to the present invention. In the blooming mode, the conveying chamber is closed by an opening and closing member, thereby allowing the medium to be sprayed out through the annular channel; in the direct flow mode, the conveying chamber is opened by an opening and closing member, thereby allowing the medium to be sprayed out through the conveying chamber.

[0023] Compared with the prior art, the advantages of this application are as follows.

[0024] The present invention provides an opening and closing component on the guide plate and a conveying cavity inside the guide plate. The opening and closing component can control the opening and closing of the conveying cavity. When the conveying cavity is closed, the fire monitor is in the blooming mode. When the conveying cavity is open, the fire monitor is in the direct current mode, which can reduce the resistance of the medium and thus increase the range.

[0025] The present invention sets up a switch controller to control the current in the current coil to achieve magnetic control of the electromagnet, thereby controlling the opening and closing of the opening and closing mechanism to realize the opening and closing of the conveying cavity.

[0026] This invention improves the spray range of a DC jet by using a shrinking cylinder and a nozzle.

[0027] The invention is designed to control the axial movement of the expansion section relative to the support section through a telescopic mechanism. In DC mode, the expansion section moves until the inner wall contacts the outer wall of the guide plate, thereby closing the annular channel and allowing the fluid to be ejected through the delivery chamber.

[0044] The invention will now be described with reference to the accompanying drawings.

[0045] It should be noted that in this application, the direction of the medium sprayed by the long-range guided fire monitor according to the present invention is described as "rear end," "rear," or similar terms, i.e. Figure 1 The left side. The destination of the medium sprayed by the long-range guided fire monitor is described as "front end," "forward," or similar terms, i.e. Figure 1 On the right side.

[0046] Figure 1 The structure of a long-range, flow-guided fire monitor 100 according to the present invention is shown. For example... Figure 1 As shown, the long-range deflector fire monitor 100 mainly includes an outer cylinder 1 and a deflector plate 21.

[0047] In this embodiment, the outer cylinder 1 is constructed in a generally cylindrical shape. The guide plate 21 is coaxially fixed inside the outer cylinder 1, and there is a gap between the outer wall of the guide plate 21 and the inner wall of the outer cylinder 1, thereby forming an annular channel 3 between the outer wall of the guide plate 21 and the inner wall of the outer cylinder 1 to allow the first medium to pass through.

[0048] A conveying chamber 24 is provided inside the guide plate 21, and an opening / closing element 212 is provided on the guide plate 21, which can open or close the conveying chamber 24. When the opening / closing element 212 closes the conveying chamber 24, the fluid behind the guide plate 21 cannot enter the conveying chamber 24, but can only be ejected through the annular channel 3 under the redirection effect of the guide plate 21. When the opening / closing element 212 opens the conveying chamber 24, the fluid behind the guide plate 21 can enter the conveying chamber 24 and finally eject from the front of the conveying chamber 24, forming a direct current jet. In the blooming mode, the opening / closing element 212 closes the conveying chamber 24, thereby allowing the medium to be ejected through the annular channel 3; in the direct current mode, the opening / closing element 212 opens the conveying chamber 24, thereby allowing the medium to be ejected through the conveying chamber 24.

[0049] In a specific embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the opening / closing element 212 is roughly fan-shaped, and multiple opening / closing elements 212 are evenly arranged circumferentially at the rear end of the guide plate 21 by hinges. In the opening / closing mode, as... Figure 1 and Figure 4 As shown, the opening / closing element 212 closes the conveying chamber 24. In DC mode, as... Figure 5 As shown, the opening / closing member 212 rotates relative to its hinge axis with the guide plate 21, opening the conveying chamber 24.

[0050] In one specific embodiment, the radially outer portion of the rear end of the guide plate 21 is configured as an edge redirection section 213, and the central portion of the rear end of the guide plate 21 is configured as a central redirection section 211. The first side 2121 of the opening / closing member 212 is hinged to the edge redirection section 213. In the opening mode, the rear side of the second side 2122 of the opening / closing member 212 approaches the front side of the central redirection section 211, thereby closing the conveying cavity 24. In the direct current mode, the second side 2122 of the opening / closing member 212 moves away from the central redirection section 211 and toward the direction of the medium, thereby opening the conveying cavity 24.

[0051] In a preferred embodiment, during the flowering mode, such as Figure 3 As shown, the second side 2122 of the opening / closing member 212 is located on the front side of the edge of the middle redirecting section 211, and at this time, the rear side of the second side 2122 axially abuts against the front side of the middle redirecting section 211. In this configuration, in the opening mode, the medium in the outer cylinder 1 is redirected along the rear end face of the guide plate 21, and the opening / closing member 212 will not affect the flow of the medium.

[0052] According to a specific embodiment of the present invention, the opening and closing member 212 is made of magnetic material, and the opening and closing member 212 is controlled by magnetic force to perform the action, thereby switching the long-range guide flow fire monitor between the bloom mode and the DC mode.

[0053] Magnetic materials are those that can interact with magnets, including but not limited to iron, cobalt, nickel, or alloys.

[0054] like Figure 1 As shown, a switch controller 7 capable of generating magnetic force is provided on the outer wall of the outer cylinder 1. The switch controller 7 includes a fixing member 71 disposed on the outer cylinder 1 and a coil 72 wound around the fixing member 71. When the coil 72 is energized, the magnetic force generated by the switch controller 7 can control the attraction force on the opening and closing member 212, thereby causing the second side 2122 of the opening and closing member 212 to axially seal against the middle redirection section 211, closing the conveying chamber 24. When the coil 72 is de-energized, the switch controller 7 no longer generates magnetic force, and when the medium flows, the fluid can push the opening and closing member 212 into the conveying chamber 24.

[0055] In a specific embodiment, such as Figure 1 As shown, the outer cylinder 1 includes an expansion section 11 and a support section 14. The expansion section 11 is constructed as a cone shape with its inner diameter gradually increasing from back to front. A guide plate 21 is disposed within the axial length of the expansion section 11, and the outer wall of the guide plate 21 is adapted to the inner wall of the expansion section 11 to form an annular channel 3. A switch controller 7 is disposed on the outer wall of the expansion section 11.

[0056] The expansion section 11 is coaxially movable on the support section 14, and the diameter of the support section 14 is adapted to the diameter of the rear end of the expansion section 11.

[0057] In this configuration, on the one hand, the spray angle in the flowering mode can be adjusted by adjusting the axial position of the expansion section 11 relative to the support section 14. Specifically, when the expansion section 11 is positioned relative to the support section 14... Figure 1 After the left side (rear end) moves, the liquid phase, through the annular channel 3, will scatter along the inner wall of the expansion section 11, causing the liquid phase to spray out in a flower-like pattern, which can increase the spray angle in the flower-like pattern. When the straight expansion section 11 moves relative to the support section 14 towards... Figure 1 After the right side (front end) moves, the liquid phase is scattered along the inner wall of the expansion section 11 through the annular channel 3, causing the liquid phase to be ejected in a flower-like pattern, which can reduce the spray angle in the flower-like mode. On the other hand, in the DC mode, by moving the expansion section 11 closer to the guide plate 21 and closing the annular channel 3, all the medium can enter the delivery chamber 24 through the opening and closing member 212, thereby increasing the range.

[0058] According to a specific embodiment of the present invention, the expansion section 11 is connected to the support section 14 via a telescopic mechanism 6, the telescopic mechanism 6 being configured to allow the expansion section 11 to move axially relative to the support section 14.

[0059] In this embodiment, the telescopic mechanism 6 includes a driver 62 and a telescopic rod 63. The driver 62 is fixedly mounted on the outer wall of the support section 14. The driver 62 is connected to the expansion section 11 through the telescopic rod 63. After the driver 62 is activated, it can drive the telescopic rod 63 to move axially, thereby causing the expansion section to move coaxially relative to the support section 14.

[0060] The guide plate 21 is part of the guide component 2, which also includes a guide core 22 coaxially fixed at the rear end of the guide plate 21. The guide core 22 is cylindrical in shape, and its outer diameter is smaller than that of the guide plate 21. The delivery cavity 24 inside the guide plate 21 is circular and coaxially disposed within the guide plate 21. In a specific embodiment, the guide plate 21 is a shell, and its internal cavity is the delivery cavity 24. A rectifier cone 8 is coaxially disposed within the delivery cavity 24. The rectifier cone 8 is disposed on the rear side wall of the delivery cavity 24, which can reduce the eddies in this part and prevent the medium entering the delivery cavity 24 from being affected by the eddies, thereby increasing the range.

[0061] In one specific embodiment, the rectifier cone 8 is configured to gradually decrease in size from back to front.

[0062] like Figure 1 As shown, the outer cylinder 1 also includes a contraction section 15 coaxially disposed at the rear end of the support section 14. The contraction section 15 is constructed with an inner diameter that gradually decreases from back to front. A water inlet section 16 is coaxially disposed at the rear end of the contraction section 15. In this configuration, the liquid phase flows sequentially from back to front along the water inlet section 16, the contraction section 15, the support section 14, and the expansion section 11, and is finally ejected from the long-range guide-type fire monitor 100. When the liquid phase passes through the contraction section 15, the size of the contraction section 15 gradually decreases, thereby increasing the flow velocity of the liquid phase. After passing through the support section 14, the liquid phase is ejected through the annular channel 3 between the expansion section 11 and the guide plate 21.

[0063] In one specific embodiment, the inlet section 16, the contraction section 15, the support section 14, and the expansion section 11 can be connected by welding or casting.

[0064] A rectifier 5 is coaxially fixedly installed in the water inlet section 16 of the outer cylinder 1. The rectifier 5 is located behind the guide member 2 and is coaxially fixedly connected to the guide core 22.

[0065] The rectifier 5 is installed in the inlet section 16 by welding or other means, and the guide core 22 is connected to the rectifier 5 by welding or other means. The rectifier 5 is well known to those skilled in the art and will not be described in detail here.

[0066] According to the present invention, such as Figure 1As shown, a connecting pipe 25 is coaxially arranged at the front end of the guide plate 21. The connecting pipe 25 is connected to the delivery chamber 24, allowing the medium in the delivery chamber 24 to enter the connecting pipe 25 and finally be ejected from the front end of the connecting pipe 25. The connecting pipe 25 can rectify and concentrate the medium, thereby increasing the jet range.

[0067] In one specific embodiment, the connecting pipe 25 includes a contraction cylinder 251 coaxially disposed at the front end of the guide plate 21 and a nozzle 252 coaxially disposed at the front end of the contraction cylinder 251. The contraction cylinder 251 is configured with a shape that decreases in size from back to front; in this embodiment, the inner wall of the contraction cylinder 251 is a tapered surface. The nozzle 252 is configured as a circular tube of uniform diameter; in this embodiment, the inner diameter of the nozzle 252 is equal to the inner diameter of the left port of the contraction cylinder 251.

[0068] In one embodiment, the diameter of the support section 14 is 0.6-0.9 times the diameter of the inlet section 16, preferably 0.8 times.

[0069] In one embodiment, the diameter of the guide core 22 is 0.1-0.4 times the diameter of the support section 14, preferably 0.2 times.

[0070] In one embodiment, the maximum diameter of the guide disk 21 is 6-8 times the diameter of the guide core 22, preferably 7 times.

[0071] In one embodiment, the axial length of the rectifier cone 8 is 1-4 times the diameter of the guide core 22, preferably 2.5 times. For example... Figure 1 As shown, the outer wall of the rectifier cone 8 is cone-shaped, with a corresponding central angle of 30°-90°, preferably 45°-60°, and more preferably 55°.

[0072] In one embodiment, the angle between the outer wall of the shrink cylinder 251 and the central axis is 10°-20°, more preferably 15°.

[0073] In one embodiment, the diameter of the nozzle 252 is 1-2 times the diameter of the guide core 22, preferably 1.5 times. The length of the nozzle 252 is 1-3 times its diameter, preferably 1.8 times.

[0074] In one embodiment, multiple opening and closing components 212 are evenly arranged in the circumferential direction, and the multiple opening and closing components 212 form a circle, preferably 4-90, and more preferably 60.

[0075] According to the present invention, a fire-fighting method is provided, which uses the long-range flow-guiding fire monitor 100 provided according to the present invention. In the bloom mode, the opening and closing member 212 is used to close the delivery chamber 24, thereby allowing the medium to be sprayed out through the annular channel 3; in the direct flow mode, the opening and closing member 212 is used to open the delivery chamber 24 and block the annular channel 3, thereby allowing the medium to be sprayed out through the delivery chamber 24.

[0076] Specifically, in the blooming mode, the switch controller 7 is turned on, generating a magnetic attraction force. The second side 2122 of the opening / closing member 212 deflects towards the direction of the medium and seals against the central redirection section 211, thereby closing the delivery chamber 24. The expansion section 11 contracts rearward through the telescopic mechanism 6. The medium enters from the inlet section 16 after being rectified by the rectifier 5, and then is ejected through the annular channel 3 between the contraction section 15, the support section 14, the guide plate 21, and the expansion section 11, forming the blooming mode.

[0077] In DC mode, switch controller 7 is turned off. The expansion section 11 is moved forward via telescopic mechanism 6 until it contacts the guide plate 21, closing the annular channel 3. The medium enters from the inlet section 16, passes through the rectifier 5, contraction section 15, and support section 14, then bursts through the opening / closing member 212, enters the conveying chamber 24, is guided by the rectifier cone 8, and is then ejected through the connecting pipe 25, forming a DC jet.
