Description

Technical Field

[0001] The present invention belongs to the technical field of fire-fighting equipment, and particularly relates to a fire-extinguishing and protective device. Background Art

[0002] During the process of fire fighting, timely and efficiently controlling the spread of fire is one of the core objectives of fire-fighting operations. Currently, common fire-fighting equipment mostly includes portable fire extinguishers, water guns, fire hoses, etc. Although these devices have a certain fire-fighting ability, there are still many limitations in actual fire scenarios. On the one hand, traditional fire-fighting devices mostly spray water in a single-point direct jet manner, with a limited spraying range and unable to achieve uniform coverage of large-area fire sources, thus affecting the fire-fighting efficiency; on the other hand, in a fire scene, the power system often interrupts, and some devices relying on electric fans or electric-driven spray systems will thus fail and cannot work properly, seriously affecting the continuity and safety of fire-fighting operations.

[0003] In addition, some existing fire-fighting devices with auxiliary air supply functions usually require an additional motor to drive the fan blades, which increases the structural complexity and energy consumption of the equipment and is not conducive to rapid deployment and on-site use. At the same time, existing devices often lack flexible adjustment of the spray angle and spraying direction during use, making it difficult to accurately adjust the fire-fighting path according to different fire source positions, easily causing waste of water resources and the existence of fire-fighting dead angles. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a fire-extinguishing and protective device, which can achieve large-range, uniform and efficient fire-extinguishing spraying.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A fire-extinguishing and protective device, including a movable moving seat, and further including: A support mechanism, which is fixed at a position close to the left side of the moving seat; A water mist spraying mechanism and a grip. The water mist spraying mechanism is used to spray water mist outwards. The water mist spraying mechanism is installed at the upper end of the support mechanism, and the water mist spraying mechanism can be adjusted at any angle. The grip is detachably installed at the right end of the water mist spraying mechanism. The water mist spraying mechanism includes a spray cylinder. Inside the spray cylinder, a fan blade, a support sleeve and an impeller are sequentially arranged from left to right. The support sleeve is fixed inside the spray cylinder through a plurality of fixing rods. The fan blade and the impeller are fixedly connected through a transmission shaft passing through the support sleeve. A water spraying driving part is arranged on the outer circumference of the impeller. The water spraying driving part can drive the impeller to rotate when spraying water. The water spraying driving part is detachably installed inside the spray cylinder; Water tank, a submersible pump is arranged inside the water tank, and the water tank is fixed on the upper surface of the movable seat. A control switch for starting the submersible pump is fixed on the right side of the water tank. A storage battery electrically connected to the submersible pump and the control switch is also installed on the movable seat; Adjusting pipe, the adjusting pipe is fixed on the movable seat, and the adjusting pipe is connected to the submersible pump and an external water pipe. The adjusting pipe can control the on-off of the connection with the submersible pump or the external water pipe, and the water outlet end of the adjusting pipe is connected to the water spraying driving part.

[0006] Further, the water spraying driving part includes an annular water pipe. A plurality of nozzles arranged in a circular pattern are fixed on the inner side of the annular water pipe, and a water inlet pipe connected to the adjusting pipe is fixed on the outer side of the annular water pipe. The plurality of nozzles are inclined at a certain angle along the circumferential direction of the annular water pipe.

[0007] Further, two clamping blocks are also fixed on the outer side of the annular water pipe. The two clamping blocks are respectively arranged on both sides of the annular water pipe, and locking grooves are formed on the end faces of the two clamping blocks.

[0008] Further, one end of the transmission shaft is fixed with a connecting head. A clamping rib is fixed on the outer circumferential surface of the connecting head. The impeller is sleeved on the connecting head, and a fixing screw is fixed through the impeller on the connecting head.

[0009] Further, the blades on the impeller are all set to be arc-shaped, and the concave surface of the arc of the blade is arranged opposite to the water spraying direction of the nozzle.

[0010] Further, a clamping groove cooperating with the two clamping blocks is arranged on the inner side surface of the spray cylinder. A first locking screw corresponding to the position of the clamping groove is installed on the outer side of the spray cylinder in a threaded manner, and one end of the first locking screw is inserted into the inner side of the locking groove.

[0011] Further, sockets are fixed at positions near the right end on the front and rear sides of the spray cylinder. A second locking screw is installed on the outer side surface of the socket in a threaded manner. The handle is set to be U-shaped, and an anti-slip sleeve is sleeved on the middle part of the handle. The two ends of the handle are respectively inserted into the inner sides of the two sockets, and locking holes are formed at positions near the two ends of the handle.

[0012] Further, a rotatable and liftable lid is installed on the upper end of the water tank. A downward hook is fixed on one side edge of the lid. A hanging plate cooperating with the hook is fixed on the side surface of the water tank. A water filling port is fixed on the lid, and a cover is installed at the water filling port.

[0013] Further, the support mechanism includes a support column. An installation groove is formed at the upper end of the support column, and an installation plate is fixed at the lower end of the support column. A bearing is installed in the installation groove. A rotating block and a swinging block are arranged above the support column. The rotating block is inserted into the inner hole of the bearing through a rotating shaft at the lower end. The upper end of the swinging block is fixedly connected to the spray cylinder, and the lower end of the swinging block is rotatably installed on the rotating block.

[0014] Further, a pipe joint connected to an external water pipe is fixed on one side of the regulating pipe. A first valve is installed on the pipe joint. A pump water pipe connected to a submersible pump is fixed near the lower end of the regulating pipe. A second valve is installed on the pump water pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting the moving seat and the supporting mechanism, the entire fire extinguishing and protection device has the structural characteristics of being movable and supportable, facilitating flexible deployment and positioning at the fire scene, enhancing the adaptability of the device in a complex fire field environment, and effectively solving the problems of difficult layout and poor operation flexibility of existing fire extinguishing devices.

[0016] By setting the water mist spraying mechanism and using the fan blades, support sleeves, impellers, nozzles and other structures inside the spray cylinder in cooperation, a stable air flow can be generated when the water spraying driving part works, and the water droplets can be evenly blown to the fire source area, achieving large-area fire extinguishing coverage and effectively improving the fire extinguishing efficiency. At the same time, the wind power source is driven by the water flow to drive the impeller, without the assistance of a motor, overcoming the limitation that the wind delivery system fails due to power failure at the fire scene and enhancing the independent reliability of the fire extinguishing system.

[0017] By setting the adjustable grip structure, the user can conveniently manually adjust the spraying direction of the spray cylinder, making the water mist spraying range and angle more accurate, meeting the fire extinguishing requirements for fire sources in different directions, and solving the problems of fixed spraying range and inconvenient adjustment method of traditional fire extinguishing equipment.

[0018] By setting the regulating pipe and configuring the first valve and the second valve structure, the device can select to use the external water source or the water source in the water tank for water supply according to the on-site water source conditions. At the same time, by setting the cooperation of the submersible pump and the storage battery, the functions of independent water supply and hydraulic air delivery under power failure are realized, thereby enhancing the continuous combat ability and emergency response ability of the overall fire extinguishing device and solving the problems of dependence on power supply and poor water source stability of existing devices.

[0019] The device forms a uniform water flow distribution through the annular water pipe and multi-nozzle structure inside the water spraying driving part. The nozzle direction matches the angle of the impeller blade structure. The impeller is directly driven to rotate by the water flow, and then the fan blades are driven to form a strong air flow, realizing the coordinated fire extinguishing effect of water and air, significantly improving the fire extinguishing speed and spray coverage effect, and effectively solving the problem of low fire extinguishing efficiency caused by the separation of water flow and air flow in existing fire extinguishing equipment.

[0020] Through the refined design of the structure, such as the clamping blocks and locking grooves between the spray cylinder and the water spraying driving part, the limiting structure between the grip and the socket, etc., the modules of the device can be quickly assembled and firmly connected, and at the same time, it is convenient for disassembly and maintenance, improving the modular degree and use convenience of the equipment, and improving the technical defects of complex structure and difficult maintenance of traditional fire extinguishing devices.

The storage battery is a high-energy lithium battery module, with an insulating box and a fixing bracket, and the circuit is connected to each electric control component through a waterproof connector to ensure stable and reliable power supply in a high-temperature and humid environment in the fire field.

[0027] The regulating pipe 2 is fixed on the moving seat 1. The regulating pipe 2 is connected to the submersible pump and the external water pipe. The regulating pipe 2 can control the on-off of the connection with the submersible pump or the external water pipe. The water outlet end of the regulating pipe 2 is connected to the water spraying driving part 37. The regulating pipe 2 is made of metal pressure-resistant pipe material and is internally provided with a dual-channel switching structure, which respectively forms a water path switching path with the pump water pipe and the pipe joint 22. The surface of the regulating pipe 2 is provided with a flow direction mark and a sealing ring slot to ensure the sealing of the connection part without water leakage.

[0028] As Figure 3 shown, the water spraying driving part 37 includes an annular water pipe 372. A plurality of nozzles 371 arranged in a circle are fixed on the inner side of the annular water pipe 372. An inlet water pipe 375 connected to the regulating pipe 2 is fixed on the outer side of the annular water pipe 372. The plurality of nozzles 371 are inclined at a certain angle along the circumferential direction of the annular water pipe 372. The annular water pipe 372 is coaxially positioned with the inner wall of the spray cylinder 31 through a welding support arm. The inlet water pipe 375 is made of high-temperature resistant corrugated pipe material, and a quick-connector structure is installed at the interface for quick disassembly and assembly. The spraying direction of the nozzles 371 is arranged opposite to the arc concave surface of the blades on the impeller 36 to form a stable tangential water flow to drive the impeller 36 to rotate.

[0029] As Figure 3 shown, two clamping blocks 373 are also fixed on the outer side of the annular water pipe 372. The two clamping blocks 373 are respectively arranged on both sides of the annular water pipe 372, and locking grooves 374 are opened on the end faces of the two clamping blocks 373. The clamping blocks 373 are of an integrally formed structure, and a guiding inclined surface is provided on the outer edge thereof to facilitate the alignment and insertion with the clamping groove 312. The locking groove 374 is of a rectangular groove structure and can be tightly fitted with the first locking screw 311 to form a reliable mechanical connection.

[0030] As Figure 4 shown, a connecting head 351 is fixed at one end of the transmission shaft 35. A clamping rib 352 is fixed on the outer circumferential surface of the connecting head 351. The impeller 36 is sleeved on the connecting head 351, and a fixing screw 353 is fixed through the impeller 36 on the connecting head 351. The clamping rib 352 is used to prevent the relative slip of the impeller 36 during the rotation process.

[0031] The blades on the impeller 36 are all arranged in an arc shape, and the arc concave surface of the blades is arranged opposite to the water spraying direction of the nozzles 371. Each blade is arranged at equal intervals along the radial direction and is designed with a shape that matches the curvature of the spray impact angle, enhancing the hydraulic driving efficiency, reducing the water resistance at the same time, and improving the rotational response sensitivity.

[0032] As Figure 5As shown in the figure, the inner side of the spray tube 31 is provided with a clamping groove 312 that cooperates with the two clamping blocks 373. The outer side of the spray tube 31 is threadedly installed with a first locking screw 311 corresponding to the position of the clamping groove 312. One end of the first locking screw 311 is inserted into the inner side of the locking groove 374; the depth of the clamping groove 312 is slightly greater than the thickness of the clamping block 373 to form a biting positioning structure. The first locking screw 311 is an external hexagonal cap screw, which can prevent falling off and loosening after being tightened.

[0033] As Figure 5 shown in the figure, sockets 313 are fixed at both the front and rear sides of the spray tube 31 near the right end. The outer side of the socket 313 is threadedly installed with a second locking screw 314. The grip 5 is set in a U shape, and an anti-slip sleeve 52 is sleeved in the middle part of the grip 5. The two ends of the grip 5 are respectively inserted into the inner sides of the two sockets 313, and locking holes 51 are opened at the positions of the grip 5 near both ends; the socket 313 is welded to the spray tube 31 by an embedded structure. The second locking screw 314 is a hand-tightening bolt structure. The grip 5 is a hollow metal pipe. The anti-slip sleeve 52 is made of silicone material to form a frosted surface. The locking hole 51 is used to cooperate with the limiting rod of the second locking screw 314 to insert to ensure that the grip 5 does not rotate after installation.

[0034] As Figure 6 shown in the figure, the upper end of the water tank 6 is installed with a box cover 61 that can be rotated and opened. A downward hook 64 is fixed on one side edge of the box cover 61. A hanging plate 65 that cooperates with the hook 64 is fixed on the side of the water tank 6. A water filling port 62 is fixed on the box cover 61, and a cover 63 is installed at the water filling port 62; the box cover 61 is connected to the rear edge of the water tank 6 through a rotating shaft and can be opened when adding water or checking. The hook 64 forms a clamping and locking structure with the hanging plate 65 through an arc-shaped elastic sheet. The water filling port 62 is located in the middle of the box cover 61. The cover 63 is a screw-on cover sealing structure, and an inner seal ring is provided to prevent the water tank from losing its seal.

[0035] As Figure 7 shown in the figure, the support mechanism 4 includes a support column 42. An installation groove 43 is opened at the upper end of the support column 42, and an installation plate 41 is fixed at the lower end of the support column 42. A bearing 47 is installed in the installation groove 43. Above the support column 42, there are a rotating block 44 and a swinging block 45. The rotating block 44 is inserted into the inner hole of the bearing 47 through a rotating shaft 46 at the lower end. The upper end of the swinging block 45 is fixedly connected to the spray tube 31, and the lower end of the swinging block 45 is rotatably installed on the rotating block 44; the installation plate 41 is fixedly connected to the left side panel of the moving seat 1 through bolts. The bearing 47 is a deep groove ball bearing, providing 360-degree rotational support. A horizontal swinging structure is formed between the rotating block 44 and the swinging block 45 through a pin shaft connection, which is used to cooperate with the spray tube 31 to adjust the fire extinguishing angle.

[0036] As Figure 8As shown, a pipe joint 22 connected to an external water pipe is fixed on one side of the regulating pipe 2, and a first valve 21 is installed on the pipe joint 22; a pump pipe connected to a submersible pump is fixed near the lower end of the regulating pipe 2, and a second valve 23 is installed on the pump pipe; both the first valve 21 and the second valve 23 are knob-type ball valve structures, which can quickly realize flow path switching; when the external water source is supplying water, the first valve 21 is opened and the second valve 23 is closed, so that the fire can be extinguished without turning on the submersible pump; when the power is off at the fire scene, the first valve 21 is closed and the second valve 23 is opened, and the submersible pump is driven by the battery to work, thereby realizing continuous water spraying and wind delivery operations, and improving the overall fire extinguishing stability and adaptability.

[0037] Example 2: Fire extinguishing protection device that is easy to move on site and stably supported In this embodiment, the mobile seat 1 is made of high-strength aluminum alloy plate (model: 6061-T6), and four Φ100mm polyurethane universal wheels are symmetrically installed at the bottom, and each universal wheel is equipped with an independent brake mechanism; a stainless steel insert is provided on the upper surface of the mobile seat 1 for fixing the support mechanism 4, and the support mechanism 4 is composed of a steel support column 42 and a mounting plate 41, which are fixedly connected by M8 bolts to ensure that the device does not shake or deviate during use.

[0038] Comparative case: Traditional fire-fighting devices are mostly fixed structures, lacking mobility and relying on manual handling for movement, which results in time-consuming and inefficient deployment, especially in large fire scenes where it is difficult to quickly locate the fire source. In contrast, this device uses a mobile base structure with brakes to enable the device to be quickly put into place and firmly supported, greatly improving the efficiency and flexibility of fire-fighting response.

[0039] Example 3: Multi-spray fire extinguishing device with self-driving air delivery system In this embodiment, the water mist spraying mechanism 3 uses a Φ120mm stainless steel spray barrel 31 as a shell, with built-in fan blades 32 (ABS material), an impeller 36 (POM material) and a nozzle 371 made of 304 stainless steel. The fan blades 32 are linked to the impeller 36 through a Φ6mm carbon steel transmission shaft 35. The nozzle 371 is arranged at a 45° inclination along the annular water pipe 372, so that the sprayed water flow directly impacts the blades on the curved arc surface of the impeller 36 and drives it to rotate; the rotating impeller 36 then drives the front fan blades 32 to form a stable forward airflow to blow the water mist outward.

[0040] Comparative case: Some existing devices need to be equipped with a separate motor-driven fan system, which relies on an external power supply, has a complex structure and cannot adapt to power outages. However, this embodiment uses a fluid-driven impeller-linked fan structure design to form wind power without the need for a motor, thereby achieving continuous spraying and long-distance fire extinguishing in a power outage environment. It has a simple and reliable structure and lower cost.

[0041] Example 4: Precision Spraying System with Multi-angle Manual Adjustment Mechanism In this embodiment, two embedded aluminum alloy sockets 313 are fixedly provided at the right end of the spray tube 31. Each socket is internally provided with a Φ10mm limit groove. The grip 5 is designed with a U-shaped anti-slip structure and adopts a TPR-coated steel pipe structure. The two ends are inserted into the socket 313 and are positioned and fixed by a screw-type second locking screw 314. The middle part of the grip 5 is covered with a rubber anti-slip sleeve 52. The spray tube 31 forms a two-stage adjustment structure with a swing block 45 and a rotating block 44. The rotating block is matched with a bearing 47 through a rotating shaft 46 to achieve omnidirectional adjustment in the up, down, left, and right directions.

[0042] Comparison case: Traditional spraying devices mostly adopt a fixed spraying direction structure, with an unchangeable direction and a limited fire extinguishing range. The omnidirectional adjustment structure in this embodiment is not only stable in structure and flexible in adjustment, but also can accurately align the target fire source intuitively through the cooperation of the handle and the user's operation, greatly improving the efficiency and accuracy of the fire extinguishing operation.

[0043] Example 5: Multi-mode Water Supply Structure with Dual Water Source Switching In this embodiment, the adjustment pipe 2 adopts a dual-channel design. One side is connected to a Φ20mm rubber pump water pipe, and the other side is connected to an external fire hose through a PE material pipe joint 22. A first valve 21 is installed on the pipe joint 22, and a second valve 23 is installed on the pump water pipe. Both valves adopt a brass three-way ball valve structure (specification DN20), and the water source switching is completed through a knob-type operation. The submersible pump is located at the bottom of the water tank 6 (model: DC24V 60W) and is controlled to start by an upper waterproof control switch 7. The storage battery is a 12V lithium battery pack (capacity 12Ah) and is connected to the pump through a quick connector.

[0044] Comparison case: Traditional fire extinguishing equipment often relies on a single water source and cannot be used normally if there is no water source or power outage at the scene. In this embodiment, by setting a dual-channel water supply of an internal water tank and an external water pipe and combining a submersible pump powered by a storage battery, continuous water supply for fire extinguishing can be achieved even under power-off conditions, enhancing the survival ability of the equipment under emergency conditions.

[0045] Example 6: Spraying Structure with Hydraulic Drive and Atomization Linkage to Improve Fire Extinguishing Efficiency In this embodiment, an annular water pipe 372 (made of 316 stainless steel) and 12 nozzles 371 (removable ceramic spray cores with a spray hole diameter of 0.3 mm) are evenly arranged circumferentially, and the setting angle of the nozzles is 42°; the annular water pipe 372 is connected to the adjusting pipe 2 through a Φ16 mm water inlet pipe 375. The high-speed water column formed by the water spray impacts the curved blade impeller 36 made of POM plastic material. The rotation of the impeller drives the front fan blade to generate a blowing force, realizing the synchronous atomization diffusion and blowing of the water mist; the water spray driving member 37 is clamped inside the spray cylinder 31 through two clamping blocks 373, closely cooperating with the clamping groove 312, and is positioned through the first locking screw 311.

[0046] Comparative case: Traditional atomizing nozzles can only generate local water mist, and the spraying coverage area is limited; by combining a hydraulic drive and a wind-sending structure, this device realizes the uniform diffusion of water mist in a large range and can actively blow it to the fire source, greatly improving the spraying distance and the fire extinguishing coverage efficiency, and solving the problem of insufficient coverage of traditional water mist devices.

[0047] Example 7: A modular design solution with detachable structure and convenient maintenance In this embodiment, a clamping block 373 and a clamping groove 312 cooperation structure is adopted between the water mist spraying mechanism and the water spray driving member. A rectangular locking groove 374 is provided at the end of the clamping block 373 and is fixed through a first locking screw 311 of M5 grade; the handle 5 is connected through a socket 313 and positioned by a second locking screw 314. All connection parts adopt a manually detachable structure. The spray cylinder, fan blade, impeller, water pipe, and nozzle can be replaced or cleaned separately, improving the maintenance convenience and service life.

[0048] Comparative case: Most traditional devices are of an integral welded structure, and the components cannot be disassembled. During maintenance, the whole needs to be replaced or professionally disassembled, with a long maintenance cycle and high cost; through the design of structural modularization and snap-fastening methods in this embodiment, the maintenance process can be quickly completed without special tools, greatly reducing the maintenance difficulty and the user training cost.

[0049] The working principle of the present invention is as follows: When carrying out fire extinguishing protection, the fire extinguishing device is moved to the fire extinguishing location by using the moving seat 1. At this time, the submersible pump is started by using the control switch 7. The submersible pump sends the water in the water tank 6 to the adjusting pipe 2, and the adjusting pipe 2 sends the water through the water inlet pipe 375 into the annular water pipe 372 and sprays it out simultaneously through multiple nozzles 371. The water sprayed out by the nozzles 371 impacts the blades on the impeller 36 to drive the impeller 36 to rotate. The rotating impeller 36 drives the fan blade 32 to rotate through the transmission shaft 35. The rotation of the fan blade 32 causes the spray cylinder 31 to blow air outward. While the spray cylinder 31 is blowing air, the water droplets generated by the spraying of the nozzles 371 are blown out evenly in a large area outward. At this time, the angle of the spray end of the spray cylinder 31 is adjusted by using the handle 5, so as to complete a more accurate, larger-range, and farther-distance fire extinguishing operation, with a better fire extinguishing effect; When connecting to an external water pipe, the second valve 23 can be closed. At this time, the first valve 21 is opened, and the external water pipe supplies water to the regulating pipe 2 and sends it to the annular water pipe 372, so as to spray water while driving the impeller 36 to drive the fan blade 32 to rotate and blow air. There is no need to additionally set up a motor and connect electricity to drive the fan blade 32 to rotate, which can better adapt to the power failure situation in the fire field, thus completing the efficient fire extinguishing operation under the power failure condition.

[0050] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
