Description

TECHNICAL FIELD

[0001] The present application relates to the field of fire fighting systems, in particular to a high-pressure water mist fire fighting system. BACKGROUND

[0002] When a fire occurs, the high-pressure water mist fire extinguishing device uses a small amount of water as the extinguishing medium, and uses a high-pressure pump group with a working pressure of not less than 10 MPa to make the specially designed small nozzles around the fire scene spray high-speed water mist with a particle size of less than 100 microns. After the water mist is sprayed into the fire scene, it quickly evaporates to form steam, increases in volume, and reduces the oxygen volume fraction, forming a barrier around the burning material to block the intake of fresh air, thereby causing suffocation around the fire source. At the same time, the water mist quickly absorbs heat during the vaporization process, which also achieves the effect of cooling and preventing high-temperature combustion.

[0003] In the related art, a high-pressure water mist fire fighting system with the authorization announcement number CN113616970A includes a device shell, an alarm and a fire detector are fixedly connected to the top end of the device shell, a receiving groove is formed in the front end of the device shell, a high-pressure water mist gun is arranged in the receiving groove, a clamping mechanism includes two second hinge shaft plates, two outer clamping arc plates, and inner plastic arc clamping plates, an arc-shaped fixed plate is fixedly connected to the bottom end of the square groove, slide rods are slidably connected to the inner walls of the two sides of the receiving groove, the two second hinge shaft plates are fixedly connected to one end of the slide rods, the two second hinge shaft plates are rotatably connected to the top end of the arc-shaped fixed plate through shafts, the two outer clamping arc plates are fixedly connected to the proximal ends of the two second hinge shaft plates, respectively, and the two inner plastic arc clamping plates are fixedly connected to the proximal ends of the two outer clamping arc plates, respectively. The clamping mechanism and the fire extinguisher are connected to achieve clamping and fixing of the fire extinguisher.

[0004] However, in the use process, in order to achieve the effect of water mist, the aperture of the water outlet hole for water outlet at the nozzle of the high-pressure water mist gun is generally small. When impurities exist in the water, if not cleaned in time, it is easy to cause blockage, affecting the outflow of water, thereby affecting the fire extinguishing efficiency, causing the fire to be unable to be immediately suppressed, and the efficiency of inhibiting the spread of the fire is poor, and the safety is low. Therefore, it needs to be improved. SUMMARY

[0005] In order to improve the problem that impurities in the water cannot be long-term blocked at the nozzle, affecting the outflow of water, thereby affecting the fire extinguishing efficiency and causing low safety, the present application provides a high-pressure water mist fire fighting system.

[0006] The high-pressure water mist fire fighting system provided by the present application adopts the following technical scheme:

[0007] A high-pressure water mist fire fighting system includes:

[0008] The spray pipe is fixedly installed on the ceiling, one end of the spray pipe is communicated with a water source, the other end is open downward, and a water pump is arranged on the spray pipe;

[0009] The water outlet plate is arranged at the end of the spray pipe far from the water source, the circumferential side wall of the water outlet plate is abutted with the inner wall of the spray pipe, and a plurality of water outlet holes are arranged on the water outlet plate;

[0010] The rotating gear is coaxially fixed on the water outlet plate and rotationally connected to the spray pipe,

[0011] The baffle is arranged in the spray pipe and is parallel to the water outlet plate, the circumferential side wall of the baffle is abutted with the inner wall of the spray pipe, and a plurality of blocking holes equal in size to the water outlet holes are arranged on the baffle;

[0012] The transmission gear is coaxially fixed on the baffle and rotationally connected to the spray pipe;

[0013] The incomplete gear is arranged between the rotating gear and the transmission gear and is rotationally connected to the spray pipe, and the incomplete gear can be engaged with the rotating gear or the transmission gear;

[0014] The rotating assembly is arranged on the spray pipe and is used for driving the incomplete gear to rotate.

[0015] By adopting the above technical scheme, when a fire occurs, the water pump is started, water flows in the spray pipe to the direction of the water outlet plate, the water first passes through the blocking holes to be divided into a plurality of thin water flows, and then further passes through the water outlet holes to form water mist and spray out, so that the effect of cooling and fire extinguishing is realized.

[0016] In this process, if impurities exist in the water flowing in the spray pipe and the diameter of the impurities is greater than the diameter of the blocking holes, the impurities will not pass through the blocking holes, so that the impurities will be blocked on the side of the baffle far from the water outlet plate, the rotating assembly is started in the process of water flowing in the spray pipe, the incomplete gear is driven to rotate, the teeth on the incomplete gear are first engaged with the transmission gear to drive the baffle to rotate, so that the side of the baffle far from the water outlet plate is turned to the side close to the water outlet plate, that is, the front and back sides are reversed, at this time, the teeth on the incomplete gear are separated from the transmission gear, so that the transmission gear stops rotating, that is, the baffle maintains the state, and the direction of the water flow does not change, so as to push the impurities on the baffle to the direction close to the water outlet plate, until the impurities are blocked on the side of the water outlet plate close to the baffle, so that the impurities on the baffle are cleaned.

[0017] Then the teeth on the incomplete gear rotate to engage with the rotating gear and drive the rotating gear to rotate, so that the water outlet plate originally close to the side of the baffle is turned to the side away from the baffle, at this time the water flow passes through the water outlet hole and pushes the impurities attached to the water outlet plate out of the water outlet plate, realizing the cleaning of the impurities on the water outlet plate, so that the impurities in the water will not block the blocking hole and the water outlet hole, thereby not affecting the water flow, and then not affecting the fire extinguishing efficiency, and the safety is higher.

[0018] During the rotation of the baffle, water will not be completely separated by the blocking hole, but the water outlet plate remains stationary, and water will eventually be separated by the water outlet hole. Similarly, when the water outlet plate rotates, the baffle remains stationary, and water will still be separated by the blocking hole and sprayed out, so that water is always in the form of water mist sprayed out of the spray pipe, that is, when cleaning impurities in water, it will not affect the fire extinguishing work.

[0019] Optionally, the rotating assembly comprises:

[0020] The mounting box is fixed on the outer wall of the spray pipe and communicates with the spray pipe, and the bottom of the mounting box is an open structure;

[0021] The water storage box is open at the top and is inserted into the mounting box, the outer wall of the water storage box abuts against the inner wall of the mounting box, the water storage box is movable in the mounting box, and a flow-through hole is formed through the side wall of the water storage box;

[0022] The connecting spring has one end fixed to the mounting box and the other end fixed to the water storage box, and is used for pulling the water storage box upward;

[0023] The linkage rack is vertically arranged and has a bottom end fixed to the water storage box;

[0024] The linkage gear is arranged on the spray pipe, the linkage gear is coaxially fixed with the incomplete gear, and the linkage gear engages with the linkage rack.

[0025] When a fire occurs, the water pump sprays water out through the spray pipe, and the water flows in the spray pipe and flows into the installation box and then into the water storage box. At this time, because the side wall of the water storage box abuts against the inner wall of the installation box, the installation box blocks the flow-through hole, so that the water storage box is a complete box. Then, when the water in the water storage box is stored to a certain amount, the gravity of the water storage box is greater than the elastic force of the connecting spring, so that the water storage box moves downward against the elastic force of the connecting spring. In this process, the linkage rack is driven to move downward, thereby driving the linkage gear to rotate, and then the rotation of the incomplete gear is realized. When the flow-through hole moves out of the installation box, the flow-through hole is in an open state, and the water in the water storage box flows out of the water storage box through the flow-through hole, so that the weight of the water storage box is reduced, thereby enabling the connecting spring to recover the deformation and pull the water storage box to move upward, that is, the linkage rack moves upward to drive the linkage gear to drive the incomplete gear to reverse, thereby realizing the reset of the rotating gear and the transmission gear.

[0026] Optionally, a limiting block is fixed on the side wall of the water storage box, and a limiting groove is vertically formed on the inner wall of the installation box, and the limiting block is inserted into the limiting groove and can move in the limiting groove.

[0027] By adopting the above technical scheme, when the water amount in the water storage box changes to drive the water storage box to move up and down, the limiting block moves in the limiting groove, and the inner wall of the limiting groove abuts against the side wall of the limiting block to limit and guide the limiting block, so that the water storage box does not deviate during movement, that is, the linkage rack does not separate from the linkage gear, thereby increasing the stability of the engagement of the linkage rack and the linkage gear.

[0028] Optionally, a magnet is embedded on the inner wall of the spray pipe, and an iron sheet that is attracted to the magnet is embedded on the circumferential side wall of the water outlet plate and the baffle.

[0029] By adopting the above technical scheme, when the baffle is rotated to be perpendicular to the spray pipe, that is, the circumferential side wall of the baffle abuts against the inner wall of the spray pipe, the iron sheet is attracted to the magnet, so that the side wall of the baffle is not easy to separate from the side wall of the spray pipe, and the baffle is not easy to rotate when water flows through the baffle, thereby increasing the stability of the baffle in the spray pipe. Similarly, when the water outlet plate is rotated to be perpendicular to the spray pipe, the iron sheet on the water outlet plate is attracted to the magnet, so that the water outlet plate is also not easy to rotate under the impact of the water flow,

[0030] Optionally, a plurality of connecting pipes with open ends are fixed on the side wall of the spray pipe, and the plurality of connecting pipes are uniformly arranged along the circumference of the spray pipe. A plurality of connecting holes are formed through the side wall of the spray pipe, and the connecting holes correspond to the connecting pipes one by one. The connecting pipes can communicate with the spray pipe through the connecting holes, and the spray pipe is provided with a blocking assembly for blocking or opening the connecting holes.

[0031] By adopting the above technical scheme, when the fire is small, the water sprayed from the spray pipe is enough to extinguish the fire, at this time, the blocking assembly blocks the connecting hole, so that the water in the spray pipe cannot enter the connecting pipe and flow out through the connecting pipe. When the fire is large, the blocking assembly opens the connecting hole, that is, the connecting pipe is in communication with the spray pipe, so that the water in the spray pipe flows into the connecting pipe through the connecting hole and flows out through the connecting pipe, so that the water sprayed per unit time is larger, and the connecting pipe is arranged on the circumferential side wall of the spray pipe, which also expands the spraying range, facilitating the control of the fire, and the spray pipe can control the water quantity and range of spraying according to the size of the fire, thereby reducing the waste of water resources.

[0032] Optionally, the blocking assembly comprises:

[0033] a blocking sleeve coaxially arranged in the spray pipe, the blocking sleeve being capable of blocking the connecting hole, and an outer wall of the blocking sleeve being in abutment with an inner wall of the spray pipe;

[0034] a tension spring, one end of the tension spring being fixed to the spray pipe and the other end being fixed to the blocking sleeve, the tension spring being used to move the blocking sleeve away from the baffle;

[0035] a connecting rope, one end of the connecting rope being fixed to the blocking sleeve and the other end extending out of the spray pipe, an outer side wall of the spray pipe being provided with a hook, and the end of the connecting rope away from the blocking sleeve being capable of being hooked on the hook.

[0036] By adopting the above technical scheme, when the fire is large, the fire is easy to spread to the end of the spray pipe, thereby burning the connecting rope, so that the blocking sleeve loses the pulling force for moving downward, the tension spring restores the deformation, pulls the blocking sleeve upward, until the blocking sleeve moves beyond the connecting hole, so that the connecting hole is not blocked, that is, the connecting hole is in an open state, so that the water in the spray pipe flows into the connecting pipe through the connecting hole and is sprayed out through the connecting pipe, thereby expanding the water quantity and the spraying range, and facilitating the control of the fire.

[0037] Optionally, the connecting rope comprises:

[0038] a high-temperature-resistant rope, one end of the high-temperature-resistant rope being fixed to the blocking sleeve and the other end extending out of the spray pipe;

[0039] a silk thread, one end of the silk thread being tied on the high-temperature-resistant rope and the other end being capable of being hooked on the hook.

[0040] By adopting the above technical scheme, when the fire is large, the silk line on the hook is burnt off, the high-temperature-resistant rope loses the downward pulling force of the silk line, the sealing sleeve loses the downward pulling, the extension spring restores the deformation, the sealing sleeve moves away from the water outlet plate, and the connecting hole is opened, that is, the spray pipe is connected with the connecting pipe, and when the extension spring pulls the sealing sleeve to the highest point, the high-temperature-resistant rope is still partially located outside the spray pipe, and the sealing sleeve maintains the state of blocking the connecting hole, and the operation is convenient.

[0041] Optionally, a guide block is fixed on the outer side wall of the sealing sleeve, and a guide groove is formed in the inner wall of the spray pipe along the moving direction of the sealing sleeve, the guide block is inserted into the guide groove and can move in the guide groove.

[0042] By adopting the above technical scheme, when the sealing sleeve moves in the spray pipe, the guide block moves in the guide groove, the inner wall of the guide groove abuts against the side wall of the guide block, the guide block is limited and guided, the sealing sleeve is not easy to deviate during the movement, and the stability of the movement of the sealing sleeve is improved. At the same time, the outer side wall of the sealing sleeve is always in abutment with the inner wall of the spray pipe, so that when the sealing sleeve blocks the connecting hole after moving, water cannot enter the gap between the sealing sleeve and the inner wall of the spray pipe into the connecting pipe, and the tightness of the blocked connecting hole is improved.

[0043] Optionally, two guide pipes are communicated with the connecting pipe, the end of the guide pipe away from the connecting pipe is bent towards the connecting pipe, and a driving assembly for driving the guide pipe to rotate is arranged in the connecting pipe.

[0044] By adopting the above technical scheme, when the connecting pipe is communicated with the spray pipe, water flows in the connecting pipe and is sprayed out through the guide pipe, the water amount sprayed out per unit time is further increased, the driving assembly is started during the water flowing in the connecting pipe, the guide pipe is driven to rotate, the spraying angle of the guide pipe is continuously changed, the spraying range is further increased, and large fire can also be controlled, and the adaptability is good.

[0045] Optionally, the driving assembly comprises:

[0046] two driving gears, the driving gears are symmetrically arranged about the central axis of the connecting pipe, an installation hole for placing the driving gears is formed in the inner wall of the connecting pipe, the driving gears are rotationally connected to the inner wall of the installation hole, and the two driving gears are engaged with each other.

[0047] Two driving rods, one-to-one corresponding to the driving gears, one end of the driving rod is coaxially fixed with the driving gear, the other end is coaxially fixed with the guide pipe, the driving rod is hollow inside, and the guide pipe communicates with the connecting pipe through the driving rod.

[0048] By adopting the above technical scheme, when the water in the spray pipe enters the connecting pipe through the connecting hole and flows in the connecting pipe away from the spray pipe, the water enters the driving rod from the end of the driving rod connected with the driving gear and flows into the guide pipe, and is discharged through the guide pipe, thereby expanding the spraying range of the connecting pipe. During the flow of water in the connecting pipe, the water flow passes between the two driving gears and pushes the teeth on the driving gears to move, thereby driving the two driving gears to rotate and drive the corresponding guide pipes to rotate, so that the spraying angle of the guide pipes is constantly changed, further expanding the spraying range.

[0049] In summary, the present application includes at least one of the following beneficial effects:

[0050] 1. During the flow of water in the spray pipe, the rotating assembly is started to drive the incomplete gear to rotate, the teeth on the incomplete gear first engage with the transmission gear to drive the baffle to rotate, so that the side of the baffle away from the water outlet plate, i.e. the side with impurities, is turned to the side close to the water outlet plate, i.e. the front and back sides are reversed. At this time, the teeth on the incomplete gear are separated from the transmission gear, so that the transmission gear stops rotating, i.e. the baffle maintains this state, and the water flow direction does not change, thereby pushing the impurities on the baffle in the direction close to the water outlet plate until they are blocked on the side of the water outlet plate close to the baffle, realizing the cleaning of the impurities on the baffle.

[0051] 2. The teeth on the incomplete gear rotate to engage with the rotating gear and drive the rotating gear to rotate, so that the side of the water outlet plate close to the baffle is turned to the side away from the baffle. At this time, the water flow passes through the water outlet hole and pushes the impurities attached to the water outlet plate out of the water outlet plate, realizing the cleaning of the impurities on the water outlet plate, so that the impurities in the water do not block the blocking hole and the water outlet hole, thereby not affecting the water flow, and then not affecting the fire extinguishing efficiency, and the safety is higher.

DETAILED DESCRIPTION

[0058] The following description will be made in conjunction with the accompanying drawings. Figures 1-5 The application is further described in detail.

Referring to Figure 1 The high-pressure water mist fire extinguishing system comprises a spray pipe 10 fixedly installed on a ceiling, one end of the spray pipe 10 is communicated with a water source, the other end of the spray pipe 10 extends out of the ceiling and is vertically downwardly open, a water pump is arranged on the spray pipe 10, and the water pump is electrically connected with a fire sensor; when a fire occurs, the fire sensor transmits a signal to the water pump, so that the water pump is started (this is prior art, and the water pump and the fire sensor are not shown in the figure).

[0060] Referring to Figure 1 and Figure 2 The end of the spray pipe 10 extending out of the ceiling is provided with a water outlet plate 20, the water outlet plate 20 is horizontally arranged in the spray pipe 10, the circumferential side wall of the water outlet plate 20 abuts against the inner wall of the spray pipe 10, a plurality of water outlet holes 21 are arranged through the end wall of the water outlet plate 20, and a baffle 30 is horizontally arranged in the spray pipe 10, the circumferential side wall of the baffle 30 abuts against the inner wall of the spray pipe 10, and a plurality of blocking holes 31 are arranged through the end wall of the baffle 30, the hole diameter of the blocking holes 31 is equal to that of the water outlet holes 21.

[0061] When a fire occurs, the water pump is started, water flows in the spray pipe 10 to the direction of the water outlet plate 20, the water first passes through the blocking holes and is divided into a plurality of thin water flows, and then further passes through the water outlet holes 21 to form water mist sprayed out, so that the effect of cooling and fire extinguishing is achieved.

[0062] Referring toFigure 2 And Figure 3 If there are impurities in the water flowing in the spray pipe 10, and the diameter of the impurities is larger than the diameter of the blocking hole 31, so that the impurities cannot pass through the blocking hole 31, and the impurities are blocked on the side of the baffle 30 away from the water outlet plate 20, which is easy to block the blocking hole 31. In order to make the impurities not affect the water flow through the blocking hole 31, a rotating rod 22 is fixed on the side wall of the water outlet plate 20, the rotating rod 22 is located at the center of the side wall of the water outlet plate 20, the rotating rod 22 is parallel to a horizontal center axis of the water outlet plate 20, the rotating rod 22 is embedded in the spray pipe 10 and is rotatably connected to the spray pipe 10, a rotating gear 23 is fixedly sleeved on the rotating rod 22, the rotating gear 23 is coaxial with the rotating rod 22, and the rotating gear 23 can rotate in the spray pipe 10.

[0064] During the flow of water in the spray pipe 10, the incomplete gear 40 is driven to rotate, the teeth on the incomplete gear 40 first mesh with the transmission gear 33 to drive the baffle 30 to rotate, so that the side of the baffle 30 originally away from the water outlet plate 20 is turned to the side close to the water outlet plate 20, that is, the front and back sides are reversed. At this time, the teeth on the incomplete gear 40 are separated from the transmission gear 33, so that the transmission gear 33 stops rotating, that is, the baffle 30 maintains this state, and the water flow direction does not change, thereby pushing the impurities on the baffle 30 towards the water outlet plate 20, until the impurities are blocked on the side of the water outlet plate 20 close to the baffle 30, realizing the cleaning of the impurities on the baffle 30.

[0065] Then the teeth on the incomplete gear 40 rotate to mesh with the rotating gear 23, and drive the rotating gear 23 to rotate, so that the side of the water outlet plate 20 originally close to the baffle 30 is turned to the side away from the baffle 30. At this time, the water flow passes through the water outlet hole 21 and flows out, and pushes the impurities attached to the water outlet plate 20 out of the water outlet plate 20, realizing the cleaning of the impurities on the water outlet plate 20, so that the impurities in the water cannot block the blocking hole 31 and the water outlet hole 21, thereby not affecting the water flow, and then not affecting the fire extinguishing efficiency, and the safety is higher.

[0066] And the baffle 30 in the process of rotation, water will not be blocked hole 31 for separation, but the water plate 20 is maintained, water will eventually be separated by the water outlet hole 21, the same, when the water plate 20 rotates, the baffle 30 is maintained, water will still be separated by the blocking hole 31 spray out, so that the water is always in the form of water mist from the spray pipe 10, that is, when cleaning water impurities will not affect the fire fighting work.

[0067] With reference to Figure 2 And Figure 3 , the spray pipe 10 is provided with a rotating assembly 50 for driving the incomplete gear 40 to rotate, the rotating assembly 50 comprises a mounting box 51, a water storage box 52 and a connecting spring 53, the mounting box 51 is fixedly installed on the outer side wall of the spray pipe 10, the mounting box 51 is communicated with the spray pipe 10, the bottom of the mounting box 51 in the vertical direction is of an open structure, the water storage box 52 is arranged in the mounting box 51, the outer side wall of the water storage box 52 abuts against the inner wall of the mounting box 51, the side wall of the water storage box 52 is provided with a flow-through hole 521, the side wall of the water storage box 52 is integrally formed with a limiting block 522, the inner wall of the mounting box 51 is provided with a limiting groove 511 in the vertical direction, the limiting block 522 is inserted into the limiting groove 511, when the water storage box 52 moves in the mounting box 51, the inner wall of the limiting groove 511 limits the limiting block 522, so that the water storage box 52 moves up and down without being easily deviated from the state of abutting against the inner wall of the mounting box 51, the connecting spring 53 is arranged in the limiting groove 511, one end of the connecting spring 53 is fixed to the inner top wall of the limiting groove 511, and the other end is fixed to the limiting block 522.

[0068] With reference to Figure 2 And Figure 3 , the rotating assembly 50 further comprises a linkage rack 54 and a linkage gear 55, the linkage rack 54 is vertically arranged, the top end of the linkage rack 54 is fixed to the bottom wall of the water storage box 52, the linkage gear 55 is engaged with the linkage rack 54, and the coaxial rotating shaft of the linkage gear 55 is fixedly connected with the incomplete gear 40.

[0069] When the fire occurs, the water pump sprays water through the spray pipe 10, the water flows in the spray pipe 10 at the same time, flows into the installation box 51 and enters the water storage box 52, at this time, because the side wall of the water storage box 52 abuts against the inner wall of the installation box 51, the installation box 51 blocks the flow-through hole 521, so that the water storage box 52 is a complete box, then when the water in the water storage box 52 is stored to a certain amount, the gravity of the water storage box 52 is greater than the elastic force of the connecting spring 53, so that the water storage box 52 overcomes the elastic force of the connecting spring 53 and moves downward, in the process, the linkage rack 54 is driven to move downward, thereby driving the linkage gear 55 to rotate, driving the incomplete gear 40 to rotate, so that the incomplete gear 40 is first engaged with the transmission gear 33, the incomplete gear 40 drives the transmission gear 33 to rotate a full circle, then separates from the transmission gear 33 and is engaged with the rotating gear 23, drives the rotating gear 23 to rotate, when the water storage box 52 moves to the lowest point of the stroke, the incomplete gear 40 drives the rotating gear 23 to rotate a full circle.

[0070] When the flow-through hole 521 moves out of the installation box 51, the flow-through hole 521 is in an open state, the water in the water storage box 52 flows out of the water storage box 52 through the flow-through hole 521, so that the weight of the water storage box 52 is reduced, thereby the connecting spring 53 recovers the deformation and pulls the water storage box 52 to move upward, that is, the linkage rack 54 moves upward, drives the linkage gear 55 to drive the incomplete gear 40 to reverse, thereby realizing the reset of the rotating gear 23 and the transmission gear 33.

[0071] Referring to Figure 4 and Figure 5 When the baffle 30 and the water outlet plate 20 are perpendicular to the spray pipe 10 and divide the water in the spray pipe 10 into fine water flow, in order to prevent the baffle 30 and the water outlet plate 20 from rotating under the impact of the water flow, the magnet 11 is fixedly embedded on the inner wall of the spray pipe 10, the iron sheet 60 is fixedly embedded on the circumferential side wall of the water outlet plate 20 and the baffle 30, the iron sheet 60 is attracted to the magnet 11, so that the baffle 30 and the water outlet plate 20 are not easy to rotate under the influence of the water flow.

[0072] Referring to Figure 2 and Figure 4When the fire is large, the water from the one end of the spray pipe 10 is not enough to control the fire, a plurality of connecting holes 12 are provided through the side wall of the spray pipe 10, the connecting holes 12 are located on the side of the baffle 30 away from the water outlet plate 20, the plurality of connecting holes 12 are uniformly distributed along the circumference of the spray pipe 10, a plurality of connecting pipes 70 are fixed on the outer wall of the spray pipe 10, the connecting pipes 70 are perpendicular to the spray pipe 10, the connecting pipes 70 correspond to the connecting holes 12 one by one, the connecting pipes 70 are penetrated at both ends, and one end of the connecting pipe 70 is in communication with the connecting hole 12. When the fire is large, the water in the spray pipe 10 flows into the connecting pipe 70 through the connecting hole 12, and is discharged through the connecting pipe 70, so that the water flows out from the one end of the spray pipe 10 and the end of the plurality of connecting pipes 70 at the same time, thereby increasing the amount of water sprayed per unit time, and the connecting pipes 70 are arranged on the circumferential side wall, which also expands the spraying range, thereby facilitating the control of the fire.

[0073] With reference to Figure 2 And Figure 4 However, when the fire is small, in order to close the connecting hole 12, so that the water in the spray pipe 10 does not flow out through the connecting pipe 70, causing waste of water resources, a plugging assembly 80 is arranged in the spray pipe 10, the plugging assembly 80 includes a plugging sleeve 81, a tension spring 82 and a connecting rope 83, the plugging sleeve 81 is coaxially arranged in the spray pipe 10, the plugging sleeve 81 is located on the side of the baffle 30 away from the water outlet plate 20, the outer wall of the plugging sleeve 81 abuts against the inner wall of the spray pipe 10, a guide block 811 is fixed on the outer side wall of the plugging sleeve 81, a guide groove 13 is provided on the inner wall of the spray pipe 10 in the vertical direction, the guide block 811 is inserted in the guide groove 13, when the plugging sleeve 81 moves, the inner wall of the guide groove 13 limits the guide block 811, so that the plugging sleeve 81 maintains the state of abutting against the inner wall of the spray pipe 10 and moves, and the plugging sleeve 81 can be moved to the connecting hole 12 and completely block the connecting hole 12.

[0074] With reference to Figure 2 And Figure 4 One end of the tension spring 82 is fixed to the inner wall of the spray pipe 10, the other end is fixed to the side of the plugging sleeve 81 away from the water outlet plate 20, one end of the connecting rope 83 is fixed to the plugging sleeve 81, the other end extends out of the spray pipe 10, a hook 120 is fixed on the outer side wall of the spray pipe 10, and the end of the connecting rope 83 away from the plugging sleeve 81 is hooked on the hook 120.

[0075] When the fire is large, it can easily spread to the end of the sprinkler pipe 10, thus burning the connecting rope 83. This causes the sealing sleeve 81 to lose its downward pulling force, and the tension spring 82 to return to its original deformation, pulling the sealing sleeve 81 upward until it moves past the connecting hole 12, leaving the connecting hole 12 unobstructed. In other words, the connecting hole 12 is in the open state, allowing water in the sprinkler pipe 10 to flow through the connecting hole 12 into the connecting pipe 70 and be sprayed out through the connecting pipe 70. This expands the water volume and spray range, making it easier to control the fire. The sprinkler pipe 10 can adjust the amount and range of water sprayed according to the size of the fire, reducing water waste.

[0076] Reference Figure 2 and Figure 3 When the connecting rope 83 burns out, to facilitate the reinstallation of the connecting rope 83 so that the sealing sleeve 81 can reseal the connecting hole 12, the connecting rope 83 includes a high-temperature resistant rope 831 and a thread 832. The high-temperature resistant rope 831 is made of glass fiber. One end of the high-temperature resistant rope 831 is fixed to the sealing sleeve 81, and the other end extends into the wall thickness of the spray pipe 10 and out of the spray pipe 10. When the tension spring 82 pulls the sealing sleeve 81 to its highest point, part of the high-temperature resistant rope 831 is still outside the spray pipe 10. One end of the thread 832 is tied to the high-temperature resistant rope 831, and the other end is hooked onto the hook 120.

[0077] When the fire is large, the thread 832 on the hook 120 is burned off, and the high-temperature resistant rope 831 loses the downward tension exerted on it by the thread 832. This means the sealing sleeve 81 loses its downward pull, the tension spring 82 returns to its original deformation, and pulls the sealing sleeve 81 away from the water outlet plate 20 until the sealing sleeve 81 opens the connection hole 12, connecting the sprinkler pipe 10 to the connecting pipe 70. Meanwhile, the tension spring 82 pulls the sealing sleeve 81 to its highest position. When the high-temperature resistant rope 831 is in use, part of it is still outside the spray pipe 10. When it is used again, pull the high-temperature resistant rope 831 out of the spray pipe 10 to make the sealing sleeve 81 move down, tie on the new silk thread 832, and then hook the silk thread 832 on the hook 120. At this time, the tension of the silk thread 832 on the sealing sleeve 81 and the elastic force of the telescopic spring are balanced, so that the sealing sleeve 81 is relatively stationary, thereby keeping the sealing sleeve 81 in the state of sealing the connection hole 12, which is convenient to operate.

[0078] Reference Figure 1 and Figure 2To further increase the spraying range, two guide tubes 110 are provided on the connecting pipe 70. The end of the guide tube 110 away from the connecting pipe 70 is bent towards the connecting pipe 70. A drive assembly 90 is provided on the connecting pipe 70. The drive assembly 90 includes two drive gears 91 and two drive rods 92. The drive gears 91 are symmetrically arranged about the central axis of the connecting pipe 70. Two mounting holes 71 are opened on the inner wall of the connecting pipe 70. The two mounting holes 71 are arranged opposite each other. The drive gears 91 are inserted into the mounting holes 71, and the top of the drive gears 91 is rotatably connected to the inner wall of the mounting holes 71. The two drive gears 91 mesh with each other. The drive rod 92 corresponds one-to-one with the drive gear 91. The drive rod 92 is a hollow tubular structure. The drive gear 91 is fixedly sleeved on the drive rod 92. The drive rod 92 and the drive gear 91 are coaxial. The bottom end of the drive rod 92 communicates with the mounting hole 71, and the other end is coaxially fixed with the guide tube 110. The guide tube 110 communicates with the drive rod 92.

[0079] When water from the spray pipe 10 enters the connecting pipe 70 through the connecting hole 12 and flows away from the spray pipe 10, the water enters the drive rod 92 from the end connected to the drive gear 91 and flows into the guide pipe 110, where it is discharged, thus expanding the spraying range of the connecting pipe 70. As the water flows through the connecting pipe 70, it passes between the two drive gears 91, pushing the teeth on the drive gears 91 to move, thereby driving the two drive gears 91 to rotate. This causes the corresponding guide pipe 110 to rotate, continuously changing the spraying angle of the guide pipe 110 and further expanding the spraying range.

[0080] The implementation principle of a high-pressure fine water mist fire extinguishing system in this application embodiment is as follows: When a fire occurs, the water pump is started, and the water flows in the spray pipe 10 toward the water outlet plate 20. The water first passes through the blocking hole and is divided into several fine water streams, and then passes through the water outlet hole 21 to form a water mist and spray it out, so as to achieve the effect of cooling and fire extinguishing.

[0081] During this process, if there are impurities in the water flowing in the spray pipe 10, and the diameter of the impurities is larger than the aperture of the blocking hole 31, the impurities will not pass through the blocking hole 31. As a result, the impurities will be blocked on the side of the baffle 30 away from the water outlet plate 20. During the flow of water in the spray pipe 10, the rotating component 50 is activated, driving the incomplete gear 40 to rotate. The teeth on the incomplete gear 40 first mesh with the transmission gear 33, driving the baffle 30 to rotate. This causes the side of the baffle 30 that was originally away from the water outlet plate 20 to the side that is closer to the water outlet plate 20, i.e., the front and back are reversed. At this time, the teeth on the incomplete gear 40 separate from the transmission gear 33, causing the transmission gear 33 to stop rotating. That is, the baffle 30 maintains this state, and the water flow direction remains unchanged. This pushes the impurities on the baffle 30 towards the direction closer to the water outlet plate 20 until they are blocked by the water outlet plate 20 on the side of the water outlet plate 20 close to the baffle 30, thus cleaning the impurities on the baffle 30.

[0082] Next, the teeth on the incomplete gear 40 rotate to mesh with the rotating gear 23, driving the rotating gear 23 to rotate. This causes the side of the water outlet plate 20 that was originally close to the baffle 30 to rotate to the side that is far away from the baffle 30. At this time, the water flows out through the water outlet hole 21 and pushes the impurities attached to the water outlet plate 20 out of the water outlet plate 20, thus cleaning the impurities on the water outlet plate 20. This prevents the impurities in the water from clogging the obstruction hole 31 and the water outlet hole 21, thereby not affecting the water flow and thus not affecting the fire extinguishing efficiency. The safety is relatively high.

[0083] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
