Description

Technical Field

[0001] The invention relates to the technical field of fire fighting equipment, and in particular to a multifunctional spray device without dead angles. Background Art

[0002] In today's complex and ever-changing firefighting scenarios, traditional firefighting equipment has exposed many problems that need to be solved. With the acceleration of urbanization, various types of buildings have sprung up like mushrooms after rain, and the environment in which fires occur has become increasingly complex and diverse. Whether it is a towering skyscraper, a winding underground building, or a crowded commercial place or a storage area with piled goods, once a fire occurs, it poses a great challenge to firefighting work.

[0003] Take a common vehicle fire as an example. The internal structure of a vehicle is complex, containing many flammable parts and electronic components, and the fire spreads rapidly. Traditional handheld fire extinguishers are limited by the spraying distance and angle, and are often difficult to penetrate into narrow and hidden fire areas such as the vehicle cab, the interior of a large truck cargo box, and local fires. It is impossible to extinguish fires in all directions, causing small fires to easily develop into large fires, bringing great difficulties to rescue work.

[0004] In large-scale building fires, smoke is a major "killer" faced by firefighters. Thick smoke not only seriously affects visibility and hinders the advancement of rescue operations, but also contains a large amount of toxic and harmful substances, posing a huge threat to the safety of firefighters' lives. However, most traditional fire sprinklers are single-function, focusing only on spraying water to extinguish fires, lacking effective smoke exhaust functions, and unable to improve the smoke conditions of the fire scene while extinguishing the fire, making it difficult to meet the needs of complex fire scenes.

[0005] Furthermore, for some special scenarios, such as fires in new energy vehicles, due to the characteristics of their batteries, fire fighting requires special cooling and isolation methods, which are difficult for traditional equipment to accurately respond to. There are also fires in small spaces. The cramped space limits the operation and deployment of equipment. Ordinary fire extinguishers cannot flexibly adjust the spray direction and it is difficult to achieve full coverage, which greatly reduces the fire extinguishing effect.

[0006] In addition, the lack of lighting and auxiliary functions during the firefighting process cannot be ignored. In a dark, smoky fire environment, firefighters are very likely to lose their way. Traditional equipment is not equipped with a special orientation indicator and cannot provide clear guidance for firefighters to avoid danger. Moreover, in communities where high-altitude operations are restricted, there is a lack of convenient and effective means of high-altitude firefighting in the face of high-altitude fire sources; in fire scenes that require alternating cover, there is no equipment that can be arranged in advance and flexibly cover, which makes the implementation of firefighting tactics subject to many obstacles.

[0007] In summary, it is urgent to develop a fire extinguishing device that can overcome the above-mentioned limitations, integrate multiple functions and has strong adaptability. The present invention comes into being based on this background. Summary of the invention

[0008] In order to solve the above problems, especially to address the deficiencies in the prior art, the present invention provides a multifunctional spray device without dead angles that can solve the above problems.

[0009] To achieve the above purpose, the present invention adopts the following technical means:

[0010] A multifunctional spray device with no dead angles comprises a spherical body, one side of the spherical body is connected to a water inlet valve, the side of the water inlet valve is connected to a position light control assembly, the side of the spherical body is connected to a plurality of groups of evenly distributed position lights and rotating nozzles, the position lights are electrically connected to the position light control assembly, the water inlet valve is connected to a frame sleeved on the outside of the spherical body, the frame is connected to the spherical body through a supporting rod, the outside of the frame is connected to a plurality of groups of evenly distributed glass breaking heads, and the end of the frame close to the water inlet valve is connected to a plurality of groups of evenly distributed hanging points.

[0011] A further solution of the present invention is that the position light control component includes a remote control frame connected to the water inlet valve, a sealing cover is hinged at the opening of the remote control frame, the remote control frame is plugged into the sealing cover through an insert block, the plug-in end of the insert block is detachably connected with a lock, a remote control switch, a mobile power supply, and a position light controller are connected in the remote control frame, the position light controller and the position light are electrically connected to the mobile power supply respectively, and the remote control switch and the position light are signal-connected to the position light controller respectively.

[0012] A further solution of the present invention is that the spherical body, the support rod and the frame are all made of stainless steel.

[0013] A further solution of the present invention is that the number of the azimuth lamps is twelve and the number of the rotating nozzles is eighteen.

[0014] A further solution of the present invention is that the azimuth lamp comprises a lampshade connected to the spherical body, and the azimuth lamp body is connected inside the lampshade.

[0015] A further solution of the present invention is that the rotary nozzle is a four-hole rotary nozzle.

[0016] A further solution of the present invention is that the frame bodies of the frame are connected by connecting rods.

[0017] A further solution of the present invention is that the hanging point is detachably connected with a fixing auxiliary accessory or a hanging buckle auxiliary accessory.

[0018] A further solution of the present invention is that the auxiliary fixing accessory comprises a fixing rod, and a fixing rod external connecting ring is connected to one side of the fixing rod.

[0019] A further solution of the present invention is that the hook auxiliary accessory includes a bundle tube body, one end of the bundle tube body is connected to a connecting ring body, the other end of the bundle tube body is plugged with a hook, and the side of the bundle tube body is connected to an external groove body.

[0020] Beneficial effects of the present invention:

[0021] 1. The present invention has no blind spots in fire extinguishing. The device is equipped with eighteen four-hole rotating nozzles, which are more numerous and have a wider spray angle than traditional nozzles, and can achieve large-flow, all-round spray coverage. Whether it is a complex internal structure of a vehicle, such as a vehicle cab, the interior and local parts of a large truck cargo box, or a special part of a new energy vehicle, the fire extinguishing agent can be accurately delivered to the fire point, ensuring that there are no blind spots for fire extinguishing, and fire extinguishing and cooling operations can be carried out efficiently.

[0022] 2. The lighting and indication of the present invention are clear. It is equipped with twelve azimuth lights, which can provide a wide range of illumination in a fire environment with thick smoke and dim light, just like a lighthouse in the dark, illuminating the surrounding environment for firefighters, enabling them to quickly identify the direction, accurately operate the equipment, and avoid getting lost. Moreover, in large, underground and other dangerous fires with fierce fires and full of smoke, it can also serve as a safety zone indicator, clearly indicating the direction of the safety zone, providing firefighters with reliable guidance for avoiding danger, and effectively protecting their personal safety.

[0023] 3. The structure of the present invention is stable and portable. The overall spherical body is combined with a stainless steel support rod and frame, which not only ensures the structural strength of the device, making it not easily damaged in a complex fire environment, but also optimizes the space occupancy due to the spherical design. Compared with traditional large-scale fire extinguishing equipment, it is smaller in size, convenient for firefighters to carry and transport, and can be quickly deployed to every corner of the fire scene.

[0024] 4. The demolition function of the present invention is practical. The glass demolition heads evenly distributed on the outside of the frame allow the device to directly use its own structure to demolish the glass of doors and windows without the need to find additional demolition tools when facing obstacles such as doors and windows, quickly open up fire-fighting channels, gain precious fire-fighting time, and effectively improve fire-fighting efficiency.

[0025] 5. The present invention performs well in special scenarios. It can play a key role in large flue fires, operations in narrow spaces, personnel decontamination at chemical accident sites, and dilution of toxic and harmful gases.

[0026] 6. The present invention has various and flexible suspension methods. There are six hanging points and matching fixing auxiliary accessories and hanging buckle auxiliary accessories. Firefighters can choose to drive the fixing rod into the wall according to the actual situation of the fire scene, such as in the scene of fire in the residential area where the aerial platform cannot enter, high-rise building, etc., and realize lifting and hanging through the external ring of the fixing rod in conjunction with the hook pulley safety rope; or use the external groove of the hanging buckle auxiliary accessory to connect the general fire equipment hook to hang at a high place, and then use the pulley hook safety rope to lift the device to the air for operation, which effectively doubles the working range and greatly expands the use scene and fire extinguishing coverage of the device.

[0027] 7. The smoke exhaust effect of the present invention is remarkable. When the working pressure exceeds 1Mpa, the water droplets sprayed by the rotating nozzle turn into water mist, which can effectively absorb smoke particles, reduce the smoke temperature at the fire scene, increase the internal pressure, and effectively prevent the occurrence of flashover and backdraft, realize precise control of the fire, and act as an isolation water wall to prevent the spread of the fire, while achieving the purpose of efficient smoke exhaust, improving the visibility at the fire scene, and creating favorable conditions for rescue operations.

[0028] 8. The present invention has strong compatibility and convenient operation. The water inlet valve adopts a universal 65 water hose interface for fire protection, which can be seamlessly connected to the fire hose, and then connected to any fire truck or indoor fire hydrant, underground fire hydrant and other external fire pipe network for water supply. It is not restricted by the type of fire water supply equipment, which greatly reduces the limitations of the use method and ensures that it can be quickly put into use under various fire infrastructure conditions. And through the remote control switch of the position light control component, firefighters can conveniently control the start of the position light and the device from a certain distance, reduce the risk of close-range operation, and improve the safety and flexibility of firefighting operations.

DETAILED DESCRIPTION

[0038] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0039] Example 1

[0040] like Figure 1 As shown, a multifunctional dead-angle-free spray device includes a spherical body 3, a water inlet valve 1 is connected to one side of the spherical body 3, a position light control assembly 2 is connected to the side of the water inlet valve 1, a plurality of groups of evenly distributed position lights 4 and a rotating nozzle 5 are connected to the side of the spherical body 3, the position lights 4 are electrically connected to the position light control assembly 2, the water inlet valve 1 is connected to a frame 7 sleeved on the outside of the spherical body 3, the frame 7 is connected to the spherical body 3 through a support rod 6, a plurality of groups of evenly distributed glass breaking heads 8 are connected to the outside of the frame 7, and a plurality of groups of evenly distributed hanging points 10 are connected to the end of the frame 7 near the water inlet valve 1.

[0041] How it works

[0042] Water supply and start-up: The water inlet valve 1 is the water supply hub of the entire device. Its connection port adopts the universal 65 fire hose interface, which can be easily connected to the fire hose, and then seamlessly connected to any fire truck, or connected to external fire pipe networks such as indoor fire hydrants and underground fire hydrants to ensure a stable water supply. When the device needs to be started, firefighters only need to place the device in a predetermined work area, such as a key fire-fighting point at the fire scene; while turning on the device, if the fire scene is dim, the firefighter can control the position light 4 to light up through the position light control component 2. The strong light emitted by the position light 4 can penetrate the thick smoke, illuminate the surrounding environment for firefighters, enable them to clearly identify the direction, and smoothly carry out firefighting operations; in dangerous large-scale, underground and other fire scenes, these position lights 4 can also be used as a sign of the safe zone to guide firefighters in the direction of avoidance.

[0043] Spray fire extinguishing and smoke exhaust: After opening the water inlet valve 1, the water flows into the spherical body 3 under pressure, and the rotating nozzle 5 on the side of the spherical body 3 starts working immediately. When the water supply pressure is within 1Mpa, the rotating nozzle 5 sprays water droplets. These larger particles of water droplets have a good fire extinguishing and cooling effect, and can quickly absorb the heat around the fire source to achieve efficient fire extinguishing. As the fire changes or the smoke exhaust demand increases, when the water supply pressure exceeds 1Mpa, the spraying pattern of the rotating nozzle 5 changes, and the water droplets become a water mist state. At this time, the fine water mist can continue to extinguish the flames on the one hand, and on the other hand, it can be fully mixed with the smoke in the fire. The water mist particles absorb the smoke particles, reduce the concentration and temperature of the smoke, increase the internal pressure of the fire, effectively prevent flashover and backfire, and play a role in isolating the fire and efficiently exhausting smoke. At the same time, it improves the visibility of the fire and helps firefighters advance rescue work. At the same time, fine water mist can play a key role in cleaning personnel and diluting toxic and harmful gases in large flue fires, operations in confined spaces, and chemical accident sites.

[0044] Auxiliary function realization: During the fire-fighting process, if there are obstacles such as doors and windows blocking the fire-fighting route, firefighters can use the glass breaking head 8 on the outside of the frame 7 to perform breaking operations without additional tools, directly using the device to break the obstacles and quickly open up a fire-fighting channel. In addition, when facing complex scenes such as fires in residential areas and high places of buildings that cannot be entered by aerial platforms, the hanging point 10 of the device can be equipped with auxiliary accessories to play a fixing role, greatly expanding the working range of the device to meet the fire-fighting needs of different heights and different positions.

[0045] In summary, the multifunctional no-dead-angle spray device of the present invention integrates multiple functions such as fire extinguishing, lighting, smoke exhaust, disinfection, dilution, demolition, and high-altitude operations through the coordinated operation of various components, providing a comprehensive and efficient solution for fire fighting work.

[0046] Example 2

[0047] like Figure 1 As shown, a multifunctional dead-angle-free spray device includes a spherical body 3, a water inlet valve 1 is connected to one side of the spherical body 3, a position light control assembly 2 is connected to the side of the water inlet valve 1, a plurality of groups of evenly distributed position lights 4 and a rotating nozzle 5 are connected to the side of the spherical body 3, the position lights 4 are electrically connected to the position light control assembly 2, the water inlet valve 1 is connected to a frame 7 sleeved on the outside of the spherical body 3, the frame 7 is connected to the spherical body 3 through a support rod 6, a plurality of groups of evenly distributed glass breaking heads 8 are connected to the outside of the frame 7, and a plurality of groups of evenly distributed hanging points 10 are connected to the end of the frame 7 near the water inlet valve 1.

[0048] like Figure 2-3 As shown, the position light control assembly 2 includes a remote control frame 201 connected to the water inlet valve 1, a sealing cover 202 is hinged at the opening of the remote control frame 201, the remote control frame 201 is plugged with the sealing cover 202 through an insert block 207, the plug-in end of the insert block 207 is detachably connected with a lock 203, a remote control switch 204, a mobile power supply 205, and a position light controller 206 are connected in the remote control frame 201, the position light controller 206 and the position light 4 are electrically connected to the mobile power supply 205, respectively, and the remote control switch 204 and the position light 4 are signal-connected to the position light controller 206, respectively.

[0049] The advantages of the above settings are:

[0050] Protection and convenience are taken into account: the sealing cover 202 hinged at the opening of the remote control frame 201, and the design of plugging the sealing cover 202 with the plug block 207 and cooperating with the detachable lock 203, provide excellent protection for the internal precision electronic components. At the fire scene, the environment is extremely harsh, with a lot of dust, high temperature heat waves, water vapor and even corrosive substances. The sealing cover 202 can effectively prevent these external impurities from invading the interior of the remote control frame 201, avoiding damage to key components such as the remote control switch 204, mobile power supply 205, and position light controller 206, and ensuring stable operation of the device. At the same time, when operation or maintenance is required, the sealing cover 202 can be easily opened by simply opening the lock 203 and pulling out the plug block 207. After the operation is completed, the sealing state can be quickly restored without affecting subsequent use.

[0051] Remote control is highly safe: The setting of the remote control switch 204 allows firefighters to control the position light 4 and the activation of the entire device from a certain safe distance. In a fire scene where the fire is fierce, the smoke is pervasive, and danger is imminent, firefighters do not need to approach the device for manual operation, which greatly reduces the probability of being exposed to high temperature, thick smoke, and collapse risks, and ensures the personal safety of firefighters. For example, when the fire suddenly changes at the fire scene, firefighters need to quickly light up the position light 4 to identify the direction or urgently activate the device to spray water to extinguish the fire. This can be achieved immediately through remote control, without the need to risk approaching the device to find a switch.

[0052] Stable power supply to ensure operation: The mobile power supply 205 provides independent power support for the position light 4 and the position light controller 206, ensuring that when the external fire power supply system fails or the power supply is unstable due to complex conditions at the fire scene, the position light 4 can still light up normally and continue to provide lighting and instructions for firefighters. This is particularly critical in scenes where the power supply infrastructure is weak or easily damaged, such as underground building fires and old residential fires, to avoid the position light 4 from failing due to power outages, leaving firefighters in the dark and lost.

[0053] Precise control improves efficiency: The position light controller 206 serves as an intermediate hub. On the one hand, it receives the signal from the remote control switch 204, and on the other hand, it accurately controls the working state of the position light 4, such as brightness adjustment, flashing mode switching, etc. In different fire environments, firefighters can send instructions to the position light controller 206 through the remote control switch 204 according to actual needs, so that the position light 4 can work in the most appropriate mode. For example, in areas with thin smoke, the brightness can be reduced to save power; in dangerous areas that require emergency warnings, switch to high-frequency flashing mode to more prominently indicate safe routes, thereby improving the efficiency of the entire position light system.

[0054] The spherical body 3, the support rod 6 and the frame 7 are all made of stainless steel.

[0055] The advantages of the above settings are:

[0056] Excellent high temperature resistance: At the fire scene, especially in the area where the fire is fierce, the temperature rises sharply. Ordinary materials are very likely to deform, soften or even melt under high temperature, causing damage to the device and unable to work normally. Stainless steel has excellent high temperature resistance and can withstand the high temperature environment in the fire scene to ensure the overall structural stability of the device. For example, in scenes such as large building fires and industrial fires, the temperature near the fire source often exceeds hundreds of degrees. The spherical body 3, support rod 6 and frame 7 made of stainless steel can still maintain the original shape and strength, providing solid support for the continued firefighting operation.

[0057] Strong corrosion resistance: In addition to high temperature, there are also various corrosive substances at the fire scene. On the one hand, the smoke produced by combustion contains a large amount of acidic and alkaline gases, such as sulfur dioxide and nitrogen oxides; on the other hand, in some special fires, such as chemical fires, leaked chemicals may cause corrosion to the device. Stainless steel products, due to their good corrosion resistance, can effectively resist the erosion of these corrosive substances, prevent parts from rusting and damage, extend the service life of the device, and reduce the cost and time consumption caused by frequent replacement of parts.

[0058] Excellent mechanical strength: During the firefighting operation, the device may be subjected to various external impacts, such as being hit by falling building components, colliding with surrounding obstacles, etc. Stainless steel has high mechanical strength and hardness. The spherical body 3, support rod 6 and frame 7 can withstand these unexpected impacts and are not prone to bending, breaking and other damages, ensuring the integrity of the device, so that it can operate reliably in a complex and changeable fire environment, and providing firefighters with a stable firefighting tool.

[0059] Hygiene and easy cleaning: After repeated use, the surface of the device will inevitably be contaminated with dust, dirt and fire-fighting residues. The surface of stainless steel is smooth and not easy to adhere to impurities, so it is relatively easy to clean. Firefighters only need to use conventional cleaning tools and detergents to easily remove stains, keep the device clean, and facilitate subsequent rapid use. In addition, its hygienic characteristics also meet the maintenance requirements of firefighting equipment and reduce potential problems such as bacterial growth.

[0060] There are twelve position lamps 4 and eighteen rotating nozzles 5 .

[0061] The advantages of the above settings are:

[0062] All-round lighting coverage: Twelve position lights 4 are evenly distributed on the side of the spherical body 3, which can achieve nearly all-round lighting coverage. At the fire scene, especially in complex environments with dim light and smoke such as large building fires and underground space fires, a sufficient number of position lights 4 ensure that light is emitted in all directions without blind spots. No matter where the firefighters are around the device, they can clearly identify the direction, quickly find the evacuation route or accurately operate the fire-fighting equipment, which greatly improves the safety of the operation and avoids falling into dangerous situations due to insufficient light. For example, in an underground parking lot fire, the billowing smoke makes the visible range extremely small, and the position lights 4 that light up in multiple directions are like bright lights in the dark, guiding the firefighters in the direction of advance and helping the rescue operation proceed smoothly.

[0063] Highly efficient fire extinguishing without blind spots: The configuration of eighteen rotating nozzles 5 greatly improves the spray coverage and density compared to the small number of nozzles in traditional fire extinguishing devices. Each rotating nozzle 5 can independently spray fire extinguishing agent in different directions, and together they can achieve an all-round attack on the fire source. Whether it is the complex internal structure of a vehicle on fire, such as the engine compartment and the corner of the cab, or the hidden fire point between the piled goods in a large warehouse fire, the numerous rotating nozzles 5 can ensure the precise delivery of the fire extinguishing agent by means of multi-angle and large-area spraying, leaving no room for the fire to escape or reignite, and efficiently achieve fire extinguishing and cooling operations.

[0064] Adapting to complex fire scene requirements: Different fire scenes have various requirements for light intensity and fire extinguishing range. In large industrial fires with rapid fire and heavy smoke, a large number of position lights 4 can be turned on to provide high-intensity lighting, penetrate the thick smoke to illuminate key areas, and assist firefighters in quickly assessing the fire and formulating fire extinguishing strategies; at the same time, eighteen rotating nozzles 5 work at full capacity, using large-flow, wide-coverage spray to deal with large areas of fire and suppress the spread of fire. In the relatively small but complex structure of new energy vehicle fire fighting, multiple rotating nozzles 5 flexibly adjust the angle to go deep into the narrow space inside the vehicle to extinguish the fire, and the position lights 4 provide sufficient light for firefighters to operate at close range. The two work together to meet the needs of special scenarios.

[0065] Redundant backup ensures stability: A large number of position lights 4 and rotating sprinklers 5 provide a certain amount of redundant backup. If individual position lights 4 are damaged due to collision, high temperature or other unexpected factors, the remaining position lights 4 can still maintain basic lighting; similarly, if some rotating sprinklers 5 are blocked or fail, other sprinklers can continue to work, ensuring that the overall function is not greatly affected, maintaining the continuous and stable operation of the device in a complex fire environment, and providing reliable support for firefighting tasks.

[0066] The azimuth lamp 4 includes a lampshade 401 connected to the spherical body 3 , and an azimuth lamp body 402 is connected inside the lampshade 401 .

[0067] The advantages of the above settings are:

[0068] Protection and focusing function: The lampshade 401, as the outer protective structure of the azimuth lamp body 402, can effectively resist various dangerous factors at the fire scene. In a fire scene, there is a large amount of dust, high-temperature airflow, and debris that may fly. The lampshade 401 can block these impurities from directly contacting the azimuth lamp body 402, preventing the lamp body from being scratched or damaged, and ensuring its stable light emission. At the same time, the lampshade 401 is usually specially designed to have a certain focusing effect, which can concentrate the light emitted by the azimuth lamp body 402 in a specific direction, enhance the lighting intensity, and make the light more capable of penetrating thick smoke. For example, at a smoky fire scene, the focused light can illuminate the surrounding environment from a farther distance, allowing firefighters to see key information such as roads and equipment at a farther distance, thereby improving rescue efficiency.

[0069] Easy installation and maintenance: The method of placing the azimuth lamp body 402 in the lampshade 401 and connecting them provides convenience for installation and subsequent maintenance. During the assembly of the device, workers only need to fix the azimuth lamp with the lampshade 401 as a whole on the spherical body 3 according to the designed position. The operation is simple and quick, which improves the production and assembly efficiency. When the azimuth lamp fails, such as when the lamp body is damaged and needs to be replaced, maintenance personnel can also relatively easily open the fixing devices of the lampshade 401, such as buckles, screws, etc., which can be designed as needed to remove the damaged azimuth lamp body 402 for replacement without complicated disassembly procedures, reducing maintenance time and costs, and ensuring that the device can be restored to normal use in a timely manner.

[0070] Optimize heat dissipation performance: The temperature at the fire scene is high, and the position lamp will generate heat when working for a long time. If the heat cannot be dissipated in time, it is easy to shorten the life of the lamp or even cause failure. The connection structure between the lampshade 401 and the position lamp body 402 usually reserves a certain heat dissipation space, and air can circulate in this gap to take away the heat generated by the lamp body. Some lampshades 401 can also be made of materials with good heat dissipation performance to further accelerate heat dissipation, ensure that the position lamp body 402 continues to work stably in a high temperature environment, maintain the lighting function, and provide reliable light source support for firefighters.

[0071] The rotary nozzle 5 is a four-hole rotary nozzle.

[0072] The advantages of the above settings are:

[0073] Increase the spray coverage: Each four-hole rotating nozzle 5 has four spray holes. Compared with single-hole or double-hole nozzles, it can spray fire extinguishing agent to a wider area during the rotation process. When the device is put into fire extinguishing operation, eighteen four-hole rotating nozzles 5 work at the same time, and many spray holes spray at multiple angles and in all directions, which greatly expands the overall spray coverage area, ensuring that whether it is a large-scale fire scene, such as a large warehouse or factory fire, or a scene with a complex internal structure, such as a vehicle cab, the interior of a large truck cargo box, etc., the fire extinguishing agent can be evenly covered in every corner, leaving no opportunity for the fire to take advantage, and effectively suppressing the spread of flames.

[0074] Improve fire extinguishing efficiency: The multi-spray hole design makes the spray of fire extinguishing agent more dispersed and uniform, and can more quickly contact with the flame and surrounding high-temperature areas. In the early stage of a fire, it is very important to quickly and effectively reduce the temperature of the fire source. The four-hole rotating nozzle 5 can deliver a large amount of fire extinguishing agent to the fire point in a short time, absorb heat, isolate oxygen, and quickly curb the development of the fire, so as to buy precious time for subsequent fire extinguishing operations, greatly improve the timeliness of fire extinguishing, and reduce the losses caused by fire.

[0075] Adapt to different fire needs: When facing fires of different intensities and types, the four-hole rotating nozzle 5 shows good adaptability. In the case of fierce fires and large flame areas, the water supply pressure can be adjusted to make the nozzle rotate at high speed, and the four nozzles spray at full power to form a large-area, high-intensity spray curtain to strongly suppress the fire; in the scene where the fire is relatively small and precise fire extinguishing is required, such as the local high-temperature point of the battery fire of new energy vehicles, the pressure is appropriately reduced, the nozzle rotates slowly, and a relatively soft and precise spray is aimed at the fire site to avoid excessive impact on the surrounding undamaged parts, so as to achieve refined fire extinguishing.

[0076] Reduce the risk of nozzle blockage: At the fire scene, the environment is complex and harsh. The water may be mixed with dust, debris, and even impurities such as ashes produced by combustion, which can easily cause nozzle blockage. Compared with the single-hole nozzle, the four-hole rotating nozzle 5 has a relatively large total nozzle area. Even if some nozzles are partially blocked, the other nozzles can still work normally and maintain a certain spray effect, so as not to make the entire nozzle fail, ensuring the continuity of the fire extinguishing operation and reducing the risk of fire extinguishing caused by nozzle failure.

[0077] Example 3

[0078] like Figure 1 As shown, a multifunctional dead-angle-free spray device includes a spherical body 3, a water inlet valve 1 is connected to one side of the spherical body 3, a position light control assembly 2 is connected to the side of the water inlet valve 1, a plurality of groups of evenly distributed position lights 4 and a rotating nozzle 5 are connected to the side of the spherical body 3, the position lights 4 are electrically connected to the position light control assembly 2, the water inlet valve 1 is connected to a frame 7 sleeved on the outside of the spherical body 3, the frame 7 is connected to the spherical body 3 through a support rod 6, a plurality of groups of evenly distributed glass breaking heads 8 are connected to the outside of the frame 7, and a plurality of groups of evenly distributed hanging points 10 are connected to the end of the frame 7 near the water inlet valve 1.

[0079] The frames of the frame 7 are connected by connecting rods 9 .

[0080] The advantages of the above settings are:

[0081] Enhanced structural stability: During firefighting operations, especially when dealing with complex fire scenes, the device may face various external force impacts, such as being hit by falling building components, colliding with obstacles during transportation, etc. The connecting rod 9 tightly connects the various frames of the frame 7 into a whole, forming a stable frame structure, effectively dispersing external forces, and avoiding deformation and damage of the frame due to excessive local force. For example, at the scene of a large building fire, the surrounding environment is chaotic. This stable structure can ensure that the device remains intact even if it suffers an accidental impact, providing reliable support for subsequent firefighting operations and ensuring that firefighting work continues.

[0082] Optimize spatial layout: The existence of the connecting rod 9 helps to rationally plan the internal space of the frame 7, so that the spherical body 3, the water inlet valve 1, the position light control assembly 2 and other components can be installed in a more orderly manner. On the one hand, it provides a stable attachment point for each component, which is convenient for accurate installation and positioning; on the other hand, it avoids the problem of mutual interference between components caused by the looseness of the frame, improves the assembly efficiency of the device, and also facilitates the maintenance personnel to inspect and replace the internal components in the later stage, saving time and labor costs.

[0083] Improved load-bearing capacity: When the device needs to bear additional loads, such as high-altitude suspension operations by connecting the fixing auxiliary accessories 11 or the hook auxiliary accessories 12 through the hanging point 10, the frame 7 strengthened by the connecting rod 9 can better bear the load weight. It evenly distributes gravity to the entire frame, preventing the risk of partial frame breakage due to excessive force, ensuring the safety and reliability of the device in high-altitude operation scenarios, expanding the scope of use of the device, and enabling it to adapt to more complex and changing firefighting needs.

[0084] like Figure 4-7 As shown, the hanging point 10 is detachably connected with a fixing auxiliary accessory 11 or a hanging auxiliary accessory 12.

[0085] The advantages of the above settings are:

[0086] Flexible adaptation to various scenarios: In firefighting practice, the fire scene environment varies greatly. For example, in old residential areas where aerial platforms cannot enter, the roads around the buildings are narrow and the space is limited. At this time, the fixing auxiliary accessories 11 are used to drive the fixing rod 1101 into the wall. With the help of the fixing rod external ring 1102 and the hook pulley safety rope, the device can be easily hung to a high place to carry out fire extinguishing and cooling operations on the outer wall of the stairs or the fire source on the higher floors. In some places with the conditions for hanging fire-fighting general equipment hooks, such as large shopping malls, factory buildings, etc., the external slot body 1204 of the hook auxiliary accessory 12 can be quickly connected to the hook, combined with the pulley hook safety rope to achieve rapid high-altitude suspension, meet the needs of high-altitude firefighting under different building structures and different terrains, and greatly broaden the application scenarios of the device.

[0087] Easy to install and disassemble quickly: The detachable connection method allows firefighters to respond quickly according to the actual situation at the emergency fire scene. When facing a fire that requires high-altitude operations, the selected auxiliary accessories can be quickly installed on the hanging point 10 without complicated tools, and the firefighting operation can be carried out in a hurry. After the firefighting task is completed, the accessories can also be easily disassembled, which is convenient for the storage, arrangement and subsequent maintenance of the device, improving the overall operation efficiency and ensuring that the device is ready to be put into battle again at any time.

[0088] Optimize load distribution and stability: Both the fixing auxiliary accessories 11 and the hook auxiliary accessories 12 can provide stable support for the device to be suspended in the air after being connected to the hanging point 10. They are carefully designed to evenly and reasonably distribute the weight of the device itself and the additional load generated after water supply to each hanging point 10, avoiding excessive force on a single point, preventing the device from shaking, tilting or even falling off in the air, and ensuring the safety and stability of high-altitude firefighting operations.

[0089] Meeting personalized tactical needs: In complex fire scene tactical arrangements, firefighters can flexibly select different auxiliary accessories based on factors such as the direction of the fire and key rescue areas. For example, when a specific high-altitude fire point needs to be attacked for a long time and accurately, the relatively stable connection provided by the fixed auxiliary accessory 11 can ensure that the device is fixed in position and achieve continuous and effective fire extinguishing and cooling; and when the device needs to be quickly transferred to different heights and directions for multi-point firefighting, the hanging auxiliary accessory 12, with its convenient connection and disassembly characteristics, cooperates with on-site firefighting facilities to meet the flexible and changeable tactical needs of firefighters and improve the coordination and effectiveness of firefighting and rescue.

[0090] The fixing auxiliary accessory 11 includes a fixing rod 1101 , and a fixing rod outer ring 1102 is connected to one side of the fixing rod 1101 .

[0091] The advantages of the above settings are:

[0092] Stable wall anchoring: In complex environments such as old residential areas and narrow streets that are inaccessible to aerial platforms, when a fire occurs, there is a lack of conditions for deploying conventional high-altitude fire-fighting equipment around the building. As a core component, the fixing rod 1101 can be powerfully driven into the wall by virtue of its own strength and appropriate length, forming a tight connection with the wall. This anchoring method uses the physical structure of the wall as a support, providing an extremely stable foundation for the suspension of subsequent devices, ensuring that when performing high-altitude fire-fighting operations, the device will not affect the fire-fighting effect due to shaking or displacement, and even in the face of adverse factors such as strong winds and building vibrations, it can still stably extinguish high-altitude fire sources.

[0093] Efficient load transfer: The design of the external ring 1102 of the fixed rod cleverly realizes the load transfer function. When the device is connected to the external ring 1102 through the hook pulley safety rope, the weight of the device itself, the water supply pressure and the dynamic force during the operation can be evenly dispersed to the wall along the fixed rod 1101. As a connecting hub, the structural strength and reasonable size design of the external ring 1102 ensure the smooth transition of force, avoid stress concentration, and effectively prevent the loosening, pulling out or wall damage of the fixed rod 1101 due to excessive local force, thereby ensuring the safety and reliability of the entire high-altitude fire extinguishing system.

[0094] Convenient operation and adaptation: From the perspective of operational convenience, firefighters can quickly drive the fixing rod 1101 into the wall using simple striking tools such as fire axe handles, without the need for complex and precise installation tools. The position and shape design of the fixing rod external ring 1102 naturally adapt to the common hook pulley safety rope. Firefighters can quickly complete the connection between the device and the external ring 1102 and start high-altitude firefighting operations in a race against time, which greatly improves the emergency response speed and meets the characteristics of fire fighting where every second counts.

[0095] The hook auxiliary accessory 12 includes a tube body 1202 , one end of which is connected to a connecting ring body 1201 , the other end of which is plugged with a hook 1203 , and the side of the tube body 1202 is connected to an external slot body 1204 .

[0096] The advantages of the above settings are:

[0097] Fast and convenient high-altitude suspension: When a fire occurs in many large public places, such as shopping malls, exhibition halls, and factory buildings, the scene is often equipped with high-altitude suspension facilities such as general fire-fighting equipment hooks. At this time, the external slot body 1204 on the side of the bundle tube body 1202 can be used. Firefighters can quickly and accurately connect it with the hook, and use the connecting ring body 1201 to cooperate with the pulley hook safety rope to hang the device firmly at a high place in a short time. The entire operation process is simple and efficient, and there is no need for complicated construction and fixing like traditional methods, which greatly saves precious time at the emergency fire scene, allowing the device to quickly be put into high-altitude firefighting operations and put out the high-altitude fire source as soon as possible.

[0098] Flexible and changeable operation adjustment: The bundle tube body 1202 has a certain flexibility. During the hanging process, it can appropriately adjust the hanging angle and orientation of the device according to the actual situation on site, such as the structural characteristics of the building, the change of the fire source location, and the wind force and direction. Firefighters only need to gently pull the safety rope or fine-tune the position of the hook 1203 to accurately aim the device at the fire point and achieve dynamic optimization of the fire-fighting operation. This flexibility ensures that in complex and changeable fire scenes, the device can always perform its fire-fighting efficiency in the best posture and effectively respond to fire threats at different locations and heights.

[0099] Reliable load bearing and dispersion: The connection ring 1201 is the main stress connection point. Its design fully considers the mechanical principles and has high strength and stability. It can bear the weight of the device and the additional load generated during water supply operation. At the same time, the bundle tube body 1202 evenly disperses the force on the connection ring 1201 to the entire accessory structure, and then transmits it to the suspension support point through the external groove body 1204, effectively avoiding stress concentration, preventing damage or falling of accessories due to excessive force on a single point, and ensuring the safety and sustainability of high-altitude firefighting operations.

[0100] Multifunctional accessories integration: The setting of hook 1203 adds more practical functions to the device. On the one hand, in special scenarios where it is inconvenient to use the external slot 1204 for hook hanging, hook 1203 can be used as a backup hanging point and connected to other suitable support structures on site to ensure that the device can still achieve high-altitude operations; on the other hand, hook 1203 can also be used to temporarily mount some small fire-fighting auxiliary tools, such as lighting fixtures, simple demolition tools, etc., so that firefighters can use them at any time during high-altitude firefighting, improving operational convenience and coordination.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here, and the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
