Description

Technical Field

[0002] High-pressure water mist machine is a fire-fighting equipment that uses water as a fire extinguishing agent. It uses a high-pressure water mist fire extinguishing system, which relies on water to be atomized into fine droplets, filling the entire protective space or wrapping and filling the gaps of the protected object, and extinguishing fires by absorbing heat and cooling, isolating oxygen, radiation attenuation, eliminating smoke and releasing toxins, etc. It is widely used in various occasions, including commercial buildings, industrial plants, and airport fire fighting, etc., because of its reliability, high efficiency, safety and environmental protection. Among them, the fine water mist nozzle is an important part of the high-pressure water mist machine. It is made of austenitic stainless steel and consists of a nozzle shell, nozzle, nozzle core, filter screen, etc. Its core component is a plurality of nozzles installed on the conical surface of the shell. Its atomization mechanism is to use the rotating liquid generated by the nozzle core in the nozzle to accelerate the ejection of the hollow diffusion cone liquid film through the nozzle channel, and use the speed difference between the liquid and the outside air to break the atomization, thereby achieving effective spraying.

[0013] Furthermore, when the upper circular plate is located at the bottom end of the fixed cavity, the height of the water outlet hole of the fixed column is higher than the height of the top surface of the upper circular plate.

[0014] The beneficial effects of the present invention are as follows: The present application provides a combination nozzle of a high-pressure fine water mist machine, which is achieved by fixing a fixed column in the vertical cavity of the nozzle shell, and the fixed column is movably connected to a movable mechanism and an auxiliary mechanism. When the combination nozzle is not in use, the movable rod moves upward under the action of a vertical spring, and pushes the auxiliary mechanism to move upward synchronously, so that the auxiliary circular plate fits with the nozzle shell, and the upper auxiliary plate closes the outlet of the nozzle, effectively preventing the nozzle in the nozzle shell from being exposed to the outside for a long time, reducing the probability of blockage caused by dust entering the nozzle, and improving the efficiency of fire fighting. When the combination nozzle is in use, the water flow will move in the vertical cavity of the nozzle shell, and part of the water flow will enter the fixed cavity of the fixed column. At this time, the water flow effectively pushes the movable rod downward, so that the auxiliary circular plate is away from the nozzle shell, and the upper auxiliary plate is away from the outlet of the nozzle, thereby achieving full spraying of water mist in the nozzle and ensuring the effect of fire fighting.

[0015] A diversion mechanism is concentrically arranged in the nozzle, and the diversion mechanism consists of a diversion pipe, a fixed part and a movable part. Since the interior of the diversion pipe is connected to the fixed cavity of the fixed column, and the fixed column is located in the nozzle shell, and the diversion pipe is located in the nozzle, the water flow flowing into the nozzle from the vertical cavity of the nozzle shell is diverted, that is, it is divided into an external water flow located between the nozzle and the diversion pipe, and an internal water flow located in the diversion pipe. The external water flow is ejected in the form of a hollow cone under the action of the fixed part and the movable part to form a water mist with a fine droplet size, thereby effectively absorbing heat and cooling the surface of the fire source, isolating oxygen, and the like. The internal water flow rotates in the diversion pipe under the action of the movable blade, and is ejected in a columnar form to form a water mist with a relatively coarse droplet size and a strong fog beam impact force, thereby effectively extinguishing the root of the fire source. In summary, the external water flow and the internal water flow are coordinated with each other to make the water mist ejected by the nozzle fully act on the fire source, which can not only reduce the water mist blind area, but also enhance the fog beam impact force, thereby improving the fire fighting effect.

[0016] By setting the shapes of the movable mechanism and the auxiliary mechanism, and enabling the movable mechanism and the auxiliary mechanism to rotate within the working mechanism and the fixed column, when the combination nozzle is not working, the auxiliary mechanism provides power for the engagement of the fixed part and the movable part. When the combination nozzle is cleaned, the staff rotates the auxiliary mechanism so that the upper auxiliary plate and the lower auxiliary plate intermittently correspond to the outlet of the nozzle, which can provide power for pushing the movable part to move back and forth on the diversion pipe. When the combination nozzle is in use, the process of water flowing from the fixed column into the diversion pipe effectively drives the movable blade to rotate, which not only makes the water flow have a rotational force in the process of diversion to enhance the impact force of the internal water flow discharge, but also can drive the auxiliary mechanism connected to the movable rod to rotate, thereby applying a driving force to the water mist sprayed by the nozzle, so that the water mist diffuses more fully.

[0017] By setting a fixed part and a movable part, the fixed part is fixedly sleeved on the diverter pipe, and the movable part is movably sleeved on the diverter pipe. When the combined nozzle is not working, the movable part is engaged with the fixed part under the action of magnetic repulsion, so that the fixed part and the movable part are superimposed, reducing the possibility of clogging of the inclined holes on the fixed part and the movable part. When the combined nozzle is cleaned, the movable part is acted upon by the auxiliary mechanism to reciprocately engage with and disengage from the fixed part, thereby cleaning the diverter mechanism and the nozzle, further preventing dust clogging and affecting the use. When the combined nozzle is working, the movable part is in a disengaged state from the fixed part. Since the fixed part and the movable part are alternately provided with inclined plates and inclined holes, they can impact and swirl the external water flow, thereby achieving sufficient atomization of the external water flow and improving the fire fighting effect.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1, a combined nozzle of a high-pressure fine water mist machine, including a nozzle housing 11, such as Figure 1-Figure 4A vertical cavity is provided at the center of the upper half of the nozzle housing 11, and an oblique cavity is provided at the lower half of the nozzle housing 11. The bottom end of the vertical cavity is connected to the top end of the oblique cavity, and the bottom end of the oblique cavity is connected to the outside, thereby providing a path for water to pass through the nozzle housing 11. The nozzle housing 11 is fixedly connected with the nozzle 12 through the oblique cavity, and the nozzle 12 is obliquely set with a high inlet and a low outlet, so that water can be discharged from the nozzle housing 11 and the nozzle 12. The nozzle 12 and the vertical cavity of the nozzle housing 11 are tangentially set, and the nozzle 12 is disposed in a tangential direction. The number of nozzles 12 is six, and the six nozzles 12 are evenly arranged around the center of the nozzle housing 11, so that when the water flows from the vertical cavity of the nozzle housing 11 into the nozzle 12, the water flow has a rotating force, which better promotes the atomization and discharge of the water flow. The top of the nozzle housing 11 is fixedly connected to the bottom end of the connecting pipe 13, and the top of the connecting pipe 13 is fixedly connected to the bottom end of the threaded pipe 14. The outer diameter of the connecting pipe 13 is larger than the outer diameter of the threaded pipe 14, and the end of the threaded pipe 14 close to the connecting pipe 13 The movable sleeve is provided with a sealing ring 15. When installing, the threaded pipe 14 is aligned with the pipeline (not shown), and the threaded pipe 14 is rotated to install the combined nozzle on the pipeline as a whole. The sealing ring 15 can enhance the sealing of the connection between the connecting pipe 13, the threaded pipe 14 and the pipeline. The filter assembly 16 is composed of a filter and a connecting rod, and the connecting rod is fixedly connected to the outer wall of the filter. The inner wall of the connecting pipe 13 is movably sleeved with the filter, and the inner wall of the connecting pipe 13 is movably connected with the connecting rod. The inner wall of the threaded pipe 14 is connected to the connecting rod. The rod is movably connected so that the filter assembly 16 is stably set between the connecting pipe 13 and the threaded pipe 14, thereby facilitating the filtering of the water flow entering the nozzle housing 11. If too many impurities adhere to the filter assembly 16, the filter assembly 16 can be directly removed from the connecting pipe 13 and the threaded pipe 14 to clean the filter assembly 16. In summary, the nozzle housing 11, nozzle 12, connecting pipe 13, threaded pipe 14, sealing ring 15 and filter assembly 16 constitute a working mechanism 1 for spraying water mist.

[0022] like Figure 2-Figure 4The nozzle housing 11 is sleeved with the fixed column 2 through the vertical cavity, and the bottom end of the fixed column 2 is fixedly connected to the bottom end of the vertical cavity of the nozzle housing 11, and the top end of the fixed column 2 can be located inside the connecting pipe 13 and contact with the bottom end of the filter assembly 16. The fixed column 2 is used to effectively support the filter assembly 16, further improve the stability of the filter assembly 16, prevent the filter assembly 16 from being damaged due to excessive impact of water flow, and extend the service life of the filter assembly 16. A fixed cavity is opened at the center position of the upper half of the fixed column 2, and the fixed cavity of the fixed column 2 is concentrically arranged with the vertical cavity of the nozzle housing 11, so that the water flow flowing into the vertical cavity of the nozzle housing 11 is diverted by the fixed column 2, a part of the water flow is located in the vertical cavity between the nozzle housing 11 and the fixed column 2, and the other part of the water flow is located in the fixed cavity of the fixed column 2, thereby providing assistance for subsequent water flow diversion and injection, and the fixed column 2 is movably connected to the upper half of the movable mechanism 3 through the fixed cavity, which is used to connect the movable mechanism 3.

[0023] like Figure 2-Figure 4 A sealed cavity is provided at the center of the lower half of the nozzle housing 11, and the nozzle housing 11 is movably connected to the lower half of the movable mechanism 3 through the sealed cavity. Since the movable mechanism 3 is connected to the working mechanism 1 and the fixed column 2, the stability of the movable mechanism 3 is ensured. Since the movable mechanism 3 is in an active state in the working mechanism 1 and the fixed column 2, the foundation is laid for the vertical movement and axial rotation of the movable mechanism 3 in the working mechanism 1 and the fixed column 2. Figure 7-Figure 9 The movable mechanism 3 includes a movable rod 31, one end of which passes through the bottom end of the fixed column 2 and is located in the fixed cavity of the fixed column 2, and the other end of the movable rod 31 passes through the bottom end of the nozzle housing 11 and is fixedly connected to the auxiliary mechanism 4, so that the movable rod 31 passes through the nozzle housing 11, the fixed column 2 and the auxiliary mechanism 4 to realize different functions of each component in different states, such as Figure 5 The outer wall of the movable rod 31 located inside the fixed cavity is fixedly sleeved with an upper circular plate 32, and the outer wall of the upper circular plate 32 is movably sleeved with the inner wall of the fixed column 2. When there is water flow in the fixed column 2, the impact force of the water flow is used to push the upper circular plate 32 downward along the inner wall of the fixed column 2 to realize the downward movement of the movable rod 31. The bottom end of the upper circular plate 32 is movably connected with a plurality of rotating balls. When the rotating balls contact the bottom end of the fixed cavity of the fixed column 2, the upper circular plate 32 has moved to the lowest position it can move. At this time, if The upper circular plate 32 rotates by itself, and the rotating ball can reduce the friction resistance between the upper circular plate 32 and the fixed column 2, so that the upper circular plate 32 can rotate more effortlessly. The outer wall of the movable rod 31 located above the upper circular plate 32 is fixedly connected with movable leaves 33, and the movable leaves 33 are arranged obliquely. The number of movable leaves 33 is three, and they are evenly arranged around the movable rod 31. When the water flow is transferred from the fixed column 2 to the diverter pipe 51, the thrust of the water flow can drive the movable leaves 33 to rotate, thereby realizing the self-rotation of the movable rod 31. Figure 6The outer wall of the movable rod 31 located inside the sealed cavity is fixedly sleeved with a lower circular plate 34, and the outer wall of the lower circular plate 34 is movably clamped with a plurality of rotating balls, and the rotating balls are in contact with the inner wall of the nozzle housing 11. When the lower circular plate 34 moves vertically or rotates axially along the sealed cavity of the nozzle housing 11, the rotating balls can reduce the friction resistance between the lower circular plate 34 and the nozzle housing 11, so that the lower circular plate 34 can rotate more labor-savingly. A lower circular plate 34 is set between the bottom end of the lower circular plate 34 and the bottom end of the sealed cavity of the nozzle housing 11. There is a vertical spring, and the vertical spring is movably sleeved on the movable rod 31. When the nozzle assembly is not working, the vertical spring stretches and its elastic force pushes the lower circular plate 34 to move upward, thereby driving the movable rod 31 and the upper circular plate 32 to move upward. When the nozzle assembly is working, the upper circular plate 32 moves downward due to the thrust of the water flow, thereby driving the movable rod 31 and the lower circular plate 34 to move downward, so that the vertical spring is compressed. In summary, the movable mechanism 3 can be vertically moved or axially rotated under the influence of the outside world, which is used to provide power for the activity of the auxiliary mechanism 4.

[0024] like Figure 1-Figure 4 The movable mechanism 3 is fixedly connected to the auxiliary mechanism 4, and the auxiliary mechanism 4 is arranged outside the nozzle housing 11 to close the outlet of the nozzle 12 to prevent dust from entering the interior of the nozzle 12 and clogging it. Figure 7-Figure 8The auxiliary mechanism 4 includes an auxiliary circular plate 41. The outer wall of the movable rod 31 located outside the nozzle housing 11 is fixedly connected with the auxiliary circular plate 41, and the auxiliary circular plate 41 is located below the nozzle housing 11. The auxiliary circular plate 41 is circular in shape, and the diameter of the auxiliary circular plate 41 is larger than the bottom diameter of the nozzle housing 11, so that the auxiliary mechanism 4 can fully fit the nozzle housing 11. The outer wall of the auxiliary circular plate 41 is fixedly connected with an upper auxiliary plate 42, and the upper auxiliary plate 42 is located above the auxiliary circular plate 41. The number of the upper auxiliary plates 42 is the same as the nozzle housing 11. 12 is equal, and the upper auxiliary plate 42 is evenly arranged around the auxiliary circular plate 41, the upper auxiliary plate 42 is inclined, and the inclination of the upper auxiliary plate 42 is the same as the inclination of the side wall of the nozzle housing 11. When the auxiliary mechanism 4 moves upward, the upper auxiliary plate 42 can fully fit with the side wall of the nozzle housing 11, and under manual operation, the upper auxiliary plate 42 can correspond to the position of the nozzle 12, so that the upper auxiliary plate 42 can close the outlet of the nozzle 12 to prevent dust from entering. The inner wall of the upper auxiliary plate 42 is magnetic. It should be noted that the upper auxiliary plate 42 can be made of either resistant The magnetic alloy material with corrosion resistance can be coated with a magnetic anti-corrosion coating, so as to provide power for pushing the movable part 7 to move. The outer wall of the auxiliary circular plate 41 between the two upper auxiliary plates 42 is fixedly connected with a lower auxiliary plate 43, and the lower auxiliary plate 43 is located below the auxiliary circular plate 41. The number of the lower auxiliary plates 43 is equal to that of the upper auxiliary plates 42, and the lower auxiliary plates 43 are evenly arranged around the auxiliary circular plate 41. The lower auxiliary plates 43 are inclined, and the direction of the lower auxiliary plates 43 is opposite to that of the upper auxiliary plates 42. In summary, the auxiliary mechanism 4 can It can open and close the outlet of the nozzle 12. Specifically, when the auxiliary mechanism 4 moves downward and rotates, it can exert a driving force on the water mist sprayed by the nozzle 12 to make the water mist diffuse more fully. Specifically, when the combined nozzle is working, the movable mechanism 3 can move downward under the push of the water flow in the fixed cavity, so that the auxiliary mechanism 4 is away from the nozzle 12 to open the outlet of the nozzle 12. When the combined nozzle is not working, the movable mechanism 3 can move upward under the action of the elastic force in the sealed cavity, so that the auxiliary mechanism 4 is close to the nozzle 12 to close the outlet of the nozzle 12.

[0025] Embodiment 2, based on embodiment 1, a combined nozzle of a high-pressure fine water mist machine further includes a diversion mechanism 5, such as Figure 1-Figure 2 , Figure 7 , Fig.10 The nozzle 12 is internally sleeved with a diverter mechanism 5 for enhancing the spraying effect of the nozzle 12. The diverter mechanism 5 includes a diverter pipe 51, a fixed part 6 and a movable part 7. Figure 11-Figure 12The diverter pipe 51 is fixedly sleeved in the nozzle 12, and the diverter pipe 51 and the nozzle 12 are arranged concentrically, so that the water flow from the vertical cavity of the nozzle housing 11 into the nozzle 12 is diverted, that is, it is divided into an external water flow located between the nozzle 12 and the diverter pipe 51, and an internal water flow located in the diverter pipe 51. The side wall of the fixed column 2 is provided with a water outlet hole, and the fixed cavity is connected to the water outlet hole. The inlet of the diverter pipe 51 is fixedly connected to the water outlet hole of the fixed column 2, and the diverter pipe 51 and the nozzle 12 are arranged tangentially. When the water flows from the fixed column 2 In the process of the column 2 being discharged into the diverter pipe 51, the water flow generates a rotational force, thereby prompting the water flow to be ejected after enhancing the impact force, so as to better carry out fire fighting, and the water flow provides power for driving the movable leaf 33 to rotate when moving, thereby prompting the movable leaf 33 to drive the movable rod 31 to rotate, so as to realize the self-rotation of the auxiliary mechanism 4. When the upper circular plate 32 is located at the bottom end of the fixed cavity, the height of the water outlet of the fixed column 2 is higher than the top surface height of the upper circular plate 32, thereby ensuring that the water flow in the fixed column 2 can be fully discharged into the diverter pipe 51, such as Figure 11-13 The upper half of the shunt pipe 51 is fixedly sleeved with a fixing member 6, and the fixing member 6 is funnel-shaped, and the wall surface of the fixing member 6 is provided with three groups of inclined holes, and the outer wall of the fixing member 6 is fixedly connected with three groups of inclined plates, and one group of inclined plates is located between two adjacent groups of inclined holes, and the lower half of the shunt pipe 51 is movably sleeved with a movable member 7, and the movable member 7 is funnel-shaped, and the wall surface of the movable member 7 is provided with three groups of inclined holes, and the inclined holes of the movable member 7 and the inclined holes of the fixing member 6 are staggered, and the inner wall of the movable member 7 is fixedly connected with three groups of inclined plates, and the inclined plates of the movable member 7 and the inclined plates of the fixing member 6 are staggered. When the water flow moves downward along the nozzle 12, the water flow is affected by The squeezing effect of the two layers of inclined holes accelerates the spraying, so that it is fully broken and atomized. Because the positions of the two layers of inclined holes are different, the water flow needs to rotate when moving to generate a rotating force, and in this process, it continuously collides with the two layers of inclined plates, further promoting the water flow to be broken and atomized, effectively improving the atomization effect of the water flow in the nozzle 12. When the nozzle 12 is not working, the inclined hole of the fixed part 6 corresponds to the inclined plate of the movable part 7, and the inclined plate of the fixed part 6 corresponds to the inclined hole of the movable part 7, so that the two can be superimposed into a whole, effectively preventing dust from adhering to the inclined holes of the fixed part 6 and the movable part 7, blocking the inclined holes and affecting the spraying of water flow, such as Figure 11-13 The movable part 7 is internally fixedly connected to the limiting block 70, and the outer wall of the shunt tube 51 is provided with a limiting groove, and the shunt tube 51 is movably connected with the limiting block 70 through the limiting groove, which effectively ensures the relativity of the positions of the inclined holes and the inclined grooves on the fixed part 6 and the movable part 7. The outer wall surface of the movable part 7 has the same magnetism as the upper auxiliary plate 42. It should be noted that the movable part 7 can be made of a corrosion-resistant magnetic alloy material, or can be coated with a magnetic anti-corrosion coating, so that the movable part 7 can cooperate with the upper auxiliary plate 42 to achieve free movement on the shunt tube 51.

[0026] The working principle of the method of the present invention is as follows: When the combined sprinkler is not working, since there is no water flow in the working mechanism 1, the movable mechanism 3 will not be subject to the downward push from the water flow. At this time, the lower circular plate 34 is located at the top of the sealed cavity under the push of the elastic force of the vertical spring, so that the movable rod 31 and the upper circular plate 32 and movable leaf 33 thereon are in an upward state, thereby causing the auxiliary circular plate 41 to move up and fit with the sprinkler housing 11, and the upper auxiliary plate 42 to close the outlet of the nozzle 12, effectively preventing the nozzle 12 in the sprinkler housing 11 from being exposed to the outside for a long time, reducing the probability of dust entering the nozzle 12 and causing blockage, and improving the efficiency of fire fighting. At the same time, since the upper auxiliary plate 42 corresponds to the outlet of the nozzle 12, the upper auxiliary plate 42 generates a magnetic repulsive force on the movable part 7 without hindrance, so that the movable part 7 moves up along the shunt pipe 51 until it is superimposed on the fixed part 6, that is, the inclined plate between the two is inserted into the inclined hole, thereby effectively reducing the possibility of blockage of the inclined holes on the fixed part 6 and the movable part 7.

[0027] When the combination nozzle needs to be cleaned, the staff rotates the auxiliary mechanism 4 so that the upper auxiliary plate 42 and the lower auxiliary plate 43 intermittently correspond to the outlet of the nozzle 12. If the upper auxiliary plate 42 corresponds to the outlet of the nozzle 12, the movable part 7 moves up along the diverter pipe 51 under the action of the magnetic repulsion force; if the lower auxiliary plate 43 corresponds to the outlet of the nozzle 12, the movable part 7 moves down along the diverter pipe 51 under the action of its own gravity. As a result, the movable part 7 can move back and forth on the diverter pipe 51, so that the movable part 7 reciprocates and engages and disengages with the fixed part 6, thereby effectively cleaning the outer wall of the diverter pipe 51 and the inner wall of the nozzle 12, further preventing dust from clogging and affecting use.

[0028] When the combined sprinkler is working, water flows into the vertical cavity of the sprinkler housing 11 through the threaded pipe 14 and the connecting pipe 13, and is filtered through the filter assembly 16. Then the water flows into the nozzle 12 through the vertical cavity of the sprinkler housing 11, and is finally ejected from the nozzle 12. During this process, the water flows in the vertical cavity of the sprinkler housing 11 and is diverted by the fixed column 2. A portion of the water flows between the sprinkler housing 11 and the fixed column 2, and then enters between the nozzle 12 and the diversion pipe 51. This portion of the water flows is called the external water flow, and another portion of the water flows in the fixed column 2, and then enters the diversion pipe 51. This portion of the water flows is called the internal water flow. When the external water flows move, they are fully swirled and broken by the action of the fixed part 6 and the movable part 7, and are ejected in the form of a hollow cone to form a water mist with a fine droplet size, thereby effectively absorbing heat and cooling the surface of the fire source, isolating oxygen, and other operations. The internal water flows first undergo the rotation of the movable blades 33 to have a rotational force, and are in the form of a columnar The water mist sprayed by the nozzle 12 can fully act on the fire source, which can not only reduce the blind area of ​​the water mist, but also enhance the impact force of the fog beam, thereby improving the fire fighting effect. At the same time, since the water flow enters the fixed cavity of the fixed column 2, the water flow thrust can push the upper circular plate 32 to move downward, thereby driving the movable rod 31 and the movable leaves 33 and the lower circular plate 34 thereon to move downward, and then the auxiliary circular plate 41 is away from the nozzle housing 11, and the upper auxiliary plate 42 is away from the outlet of the nozzle 12. After that, when the water flow is transferred from the fixed cavity of the fixed column 2 to the inside of the diverter pipe 51, it effectively promotes the rotation of the movable leaves 33, thereby driving the rotation of the movable rod 31, and then realizing the rotation of the auxiliary mechanism 4, so as to apply a driving force to the water mist sprayed by the nozzle 12, so that the water mist can diffuse more fully.
