Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, specifically to a production method and device for a single-cylinder internal combustion powered combined fire hose, which is suitable for special fire-fighting scenarios requiring instantaneous high flow rate and long range, such as petrochemical fires, forest fires, and external fires of high-rise buildings. Background Technology

[0002] In specialized firefighting applications, particularly those requiring instantaneous high-flow-rate, long-range fires such as petrochemical fires, forest fires, and fires outside high-rise buildings, traditional electric or hydraulically driven fire pumps present significant bottlenecks. These traditional devices typically have low power density, complex system structures, and slow response times, making it difficult to provide explosive, high-flow-rate water jets in a short period.

[0003] As a mature and efficient power unit, the internal combustion engine's advantages of high instantaneous power and high energy density have been fully verified in fields such as vehicles and machinery. However, the direct application of the internal combustion engine to portable fire-fighting equipment, especially the technical solution of directly converting its output form from rotational mechanical energy to water jet kinetic energy, has not been reported in the existing technology.

[0004] Existing fire hoses or water cannons mostly use a continuous water supply mode, which can maintain water flow for a relatively long time, but the instantaneous impact force is limited and it is difficult to effectively suppress deflagration fires. Therefore, there is an urgent need for a fire-fighting device and its manufacturing method that can combine the high-power characteristics of internal combustion engines with the advantages of direct hydraulic transmission to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a method and apparatus for producing a compact, powerful, and rapidly responsive single-cylinder internal combustion engine-powered combined fire hose reel. This method innovatively transplants the complete structure and working principle of a single-cylinder internal combustion engine into fire equipment production. It directly drives the water medium through the combustion of the internal combustion engine, achieving a pulsed, high-intensity water jet. Simultaneously, it is supplemented by a gunpowder-projection water cannon mechanism, forming a multi-functional combined fire extinguishing device.

[0006] To achieve the above objectives, the present invention provides the following technical solution; A method for producing a single-cylinder internal combustion powered combined fire hose nozzle includes the following steps; Mechanism forming steps: Form a single-cylinder internal combustion pulse water spray mechanism and a gunpowder projection water cannon mechanism respectively. The forming method of the single-cylinder internal combustion pulse water spray mechanism is as follows: Use a cylindrical shell as an engine cylinder, and set a piston that can slide back and forth in the shell. The piston top surface and the inner wall of the shell form a combustion chamber. The intake valve assembly, exhaust valve assembly, fuel injector and electronic igniter are set on the combustion chamber. The water outlet pipe and water injection pipe are set at the upper end of the shell, so that the space above the piston is constructed as a water cavity. Integrated assembly steps: The single-cylinder internal combustion pulse water spray mechanism and the gunpowder projection water cannon mechanism are fixedly mounted side by side on the base; Support connection steps: The base is hinged to the top of the jack via an angle adjustment seat to form a support structure with an adjustable pitch angle; Control system configuration steps: Configure the control system to electrically connect the control system to the ball valve, water injection pipe, intake valve assembly, exhaust valve assembly, fuel injector and electronic igniter of the single-cylinder internal combustion pulse water injection mechanism, and configure it to control the coordinated operation of each component according to a predetermined working cycle.

The deflagration water spraying process involves controlling the intake valve to close, sequentially controlling the fuel injector to inject fuel and the electronic igniter to ignite the mixture in the combustion chamber, causing the piston to rapidly rise and eject the water above it from the water outlet pipe at high speed. Exhaust pressure relief procedure: Control the exhaust valve to open and discharge the exhaust gas from the combustion chamber.

[0008] Furthermore, in the mechanism forming step, the intake valve assembly is formed by providing an intake valve, an intake valve spring, an intake valve guide, an intake valve retaining ring, and an intake valve solenoid valve; the exhaust valve assembly is formed by providing an exhaust valve, an exhaust valve spring, an exhaust valve guide, an exhaust valve retaining ring, and an exhaust valve solenoid valve.

[0009] Furthermore, in the mechanism forming step, the forming method of the gunpowder-projecting water cannon mechanism is as follows: forming a water tank for storing water, setting an electric heating coil and a plastic sealing film at the bottom of the water tank, forming an outer shell for accommodating the water tank, forming a gunpowder chamber containing the launching gunpowder, setting a plug with a fuse hole in the gunpowder chamber, forming a gunpowder chamber base for installing the gunpowder chamber, and forming a buffer launching assembly including a buffer spring, a buffer base, a sliding sleeve and a sliding rod.

[0010] Furthermore, in the supporting connection step, the angle adjustment seat adopts a sector gear adjustment mechanism or a hydraulic adjustment mechanism to enable the base to adjust the pitch angle within the range of -10° to +45° in the vertical plane.

[0011] The present invention also provides a single-cylinder internal combustion powered combined fire hose, comprising: A single-cylinder internal combustion pulse water injection mechanism, whose structure and working cycle principle are equivalent to a single-cylinder two-stroke engine that uses water as the working medium for transmission components. A gunpowder-projectile water cannon mechanism; A jack used for support and leveling; A base, on which the single-cylinder internal combustion pulse water jet mechanism and the gunpowder-projection water cannon mechanism are fixedly mounted side by side; and An angle adjustment seat is provided, through which the base is hinged to the top of the jack.

[0012] Furthermore, the single-cylinder internal combustion pulse water injection mechanism includes: a cylindrical housing serving as an engine cylinder block; a piston serving as an engine piston, reciprocatingly and slidably disposed within the housing, the piston being fitted with piston rings; a combustion chamber enclosed by the top surface of the piston and the inner wall of the housing; an intake valve assembly and an exhaust valve assembly disposed on the combustion chamber; a fuel injector and an electronic igniter disposed on the combustion chamber; a water outlet pipe and a water inlet pipe disposed at the upper end of the housing; and a ball valve disposed on the water outlet pipe.

[0013] Furthermore, the intake valve assembly includes an intake valve, an intake valve spring, an intake valve guide, an intake valve retainer, and an intake valve solenoid valve; the exhaust valve assembly includes an exhaust valve, an exhaust valve spring, an exhaust valve guide, an exhaust valve retainer, and an exhaust valve solenoid valve.

[0014] Furthermore, it also includes a control system, which is electrically connected to the ball valve, water injection pipe, intake valve assembly, exhaust valve assembly, fuel injector and electronic igniter, and is configured to control the various components to work together in a predetermined working cycle.

[0015] Furthermore, the gunpowder-projectile water cannon mechanism includes: a water tank for storing water; an electric heating coil and a plastic sealing film for sealing the water tank; an outer casing for accommodating the water tank; a gunpowder chamber containing the propellant; a plug disposed within the gunpowder chamber, the plug having a fuse hole; a gunpowder chamber base for mounting the gunpowder chamber; a buffer launch assembly including a buffer spring, a buffer base, a sliding sleeve, and a sliding rod; and a sealing cover disposed on the top of the sealed water tank, the sealing cover being hinged to the sealed water tank via a hinge, the hinge axis of the hinge being connected to the sealing cover and the motor respectively.

[0016] Compared with the prior art, the present invention has the following significant advantages; 1. Revolutionary improvement in power performance; by directly utilizing the high energy density characteristics of internal combustion engine detonation, it can generate instantaneous pressure far exceeding that of traditional water pumps within milliseconds, achieving ultra-high-speed water jet launch, greatly improving range, impact force and fire extinguishing efficiency.

[0017] 2. Extremely fast response speed; from the issuance of the ignition command to the formation of the high-pressure jet, the entire process is completed within tens of milliseconds, realizing a true "burst" water spray, which is particularly suitable for suppressing initial fires, deflagration fires and other scenarios that require rapid response.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of the present invention, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are only for explaining the present invention and are not intended to limit the scope of the present invention. Example

[0025] like Figure 1 and Figure 2 As shown, the single-cylinder internal combustion powered combined fire hose reel of the present invention mainly comprises two parts: a single-cylinder internal combustion pulse water spray mechanism 1, which serves as the main fire extinguishing unit, and a gunpowder projection water cannon mechanism 2, which serves as the auxiliary delivery unit. These two mechanisms are fixedly installed side by side on a common base 4, forming a compact assembly.

[0026] The rear of the base 4 is hinged to the top of the jack 3 via an angle adjustment seat 5. The angle adjustment seat 5 can employ a sector gear adjustment mechanism or a hydraulic adjustment mechanism, allowing the base 4 to be adjusted in pitch angle within the range of -10° to +45° in the vertical plane. The jack 3 can be manually operated or hydraulically operated, used to adjust the height and level of the entire device to adapt to uneven ground conditions.

[0027] I. Production and Structure of Single-Cylinder Internal Combustion Pulse Water Injection Mechanism like Figures 3 to 5 As shown, the single-cylinder internal combustion pulse water injection mechanism 1 is the core innovation of this invention. In terms of physical structure, this mechanism is equivalent to a small single-cylinder two-stroke gasoline engine without the crankcase and crankshaft connecting rod, and directly couples the piston's power output to the water medium.

[0028] The cylinder block and piston: The cylindrical housing 101 serves as the engine cylinder block, made of high-temperature and high-pressure resistant alloy steel, with its inner wall precision-machined to meet the precision requirements of engine cylinders. The piston 103 is made of aluminum alloy, and at least two piston rings 104 are installed on its outer cylindrical surface to ensure sealing during the piston's reciprocating motion within the housing 101. The piston 103's motion, clearance, and lubrication requirements are consistent with those of traditional internal combustion engine pistons.

[0029] Combustion chamber; the combustion chamber 118 is a sealed space formed by the top surface of piston 103 and the upper part of the inner wall of housing 101. The volume and shape of combustion chamber 118 are optimized to facilitate the formation of air-fuel mixture and complete combustion. Multiple functional interfaces are provided on the top of combustion chamber 118.

[0030] Valve train; The combustion chamber 118 is equipped with a complete intake valve assembly and an exhaust valve assembly, the structure of which is equivalent to the overhead valve mechanism of a small gasoline engine.

[0031] The intake valve assembly includes an intake valve 117, an intake valve spring 116, an intake valve guide 115, an intake valve retaining ring 114, and an intake valve solenoid valve 113. The intake valve guide 115 is press-fitted into a machined hole in the upper part of the housing 101, providing precise guidance for the intake valve 117. The intake valve spring 116 provides the closing force for the valve. The intake valve solenoid valve 113 receives control signals and controls the opening and closing of the intake valve 117 via a push rod or direct pull, replacing the camshaft and rocker arm mechanism of a traditional engine.

[0032] The exhaust valve assembly includes: an exhaust valve 105, an exhaust valve spring 106, an exhaust valve guide 107, an exhaust valve retaining ring 108, and an exhaust valve solenoid valve 109. Its installation and working principle are symmetrically arranged with the intake valve assembly.

[0033] The advantages of using solenoid valves to control valves are fast response speed (down to millisecond level), precise control, and easy integration with electronic control systems.

[0034] The fuel and ignition system includes a fuel injector 112 mounted on the side wall or top of the combustion chamber 118, connected to an external fuel supply system (such as a high-pressure fuel pump or fuel tank) via a fuel inlet pipe 111. The fuel injector 112 can be electromagnetic or piezoelectric, precisely injecting atomized fuel according to a control signal. An electronic igniter 110 (i.e., spark plug) is mounted on the top or side wall of the combustion chamber 118, with its electrodes extending into the combustion chamber. Ignition voltage is provided by a high-voltage coil, generating an electric spark at a precise moment to ignite the air-fuel mixture.

[0035] The hydraulic transmission output system is the fundamental difference between this mechanism and the traditional internal combustion engine, and it is also the key to achieving pulse water injection.

[0036] The inner cavity of the housing 101 above the piston 103 forms a variable sealed water chamber. Both the outlet pipe 120 and the injection pipe 121 are connected to this water chamber. The injection pipe 121 connects to an external water source (such as a fire truck pump or water tank) and is equipped with an inlet control valve. The outlet pipe 120 is the outlet for the high-pressure water jet and is typically designed as a tapered nozzle to further increase the water flow velocity. A ball valve 119 is installed on the outlet pipe 120 to seal the water chamber during non-spraying phases and ensure unidirectional high-speed water flow during spraying phases.

[0037] II. Production and Structure of Gunpowder Projection Water Cannon Mechanism like Figures 6 to 9 As shown, the gunpowder-projectile water cannon mechanism 2 provides another method for delivering fire extinguishing projectiles.

[0038] Water storage section; Water tank 201 is a pressure-resistant container used to store fire extinguishing water or additive solutions. Its bottom is sealed by a plastic sealing film 203, and an electric heating coil 202 is wrapped around the outside of the plastic sealing film 203. When the electric heating coil 202 is energized, it generates high temperature, which can heat-seal the plastic sealing film 203 to the bottom of the water tank 201.

[0039] The projectile propulsion system includes an outer casing 204 that houses the rear of the water tank 201. The propellant magazine 205 contains launching propellant, and a plug 206 seals the rear of the propellant magazine 205, with a fuse hole 212 for mounting an electric igniter. The propellant magazine base 207 secures the propellant magazine 205 and connects to the buffer launch assembly.

[0040] The buffer and guiding section includes a slide bar 211, a sliding sleeve 210, a buffer spring 208, and a buffer base 209. During launch, the gunpowder explosion generates high-pressure gas, which propels the gunpowder magazine base 207 and the entire recoil section backward along the slide bar 211. The buffer spring 208 absorbs most of the recoil energy and simultaneously ejects water from the water tank forward at high speed.

[0041] A sealing and opening mechanism includes a sealing cover 213 located on top of the sealed water tank 201. The sealing cover 213 is hinged to the sealed water tank 201 via a hinge 214. The hinge shaft of the hinge 214 is connected to both the sealing cover 213 and a motor 215. When the motor 215, which is fixedly mounted on the top of the water tank 201, is started, the motor 215 drives the hinge shaft to rotate. The hinge shaft then drives the hinge sleeve on the hinge 214, which is fixedly connected to the sealing cover 213, to rotate, thereby opening the sealing cover 213.

[0042] The working cycle is as follows: After launch, the water tank 201 and the outer casing 204 are unlocked and separated. The plastic sealing film is replaced, and the heating coil 202 is energized to heat-seal the plastic sealing film onto the bottom of the water tank 201, thus separating the water tank 201 from the propellant tank 205. At the same time, the launch propellant is placed into the propellant tank 205. After completion, the water tank 201 and the outer casing 204 are reconnected and locked. Water is then injected from the top of the water tank 201, preparing for the next launch.

[0043] III. Production and Configuration of Control Systems In this embodiment, the single-cylinder internal combustion pulse water injection mechanism 1 further includes a control system. This control system can be an independent electronic control unit or a control circuit integrated into the equipment's operation panel.

[0044] The control system is electrically connected to the actuator of ball valve 119, the water inlet valve of water injection pipe 121, the intake valve solenoid valve 113, the exhaust valve solenoid valve 109, the fuel injector 112 and the electronic igniter 110, and is configured to drive the components to work together according to a predetermined logic program to achieve the following complete working cycle. (1) Water injection and piston downward movement: The control system first issues a command to ensure that the ball valve 119 is closed, sealing the water outlet pipe. At the same time, the water inlet valve of the water injection pipe 121 is opened, and external pressurized water (usually provided by an auxiliary water pump) is injected into the water chamber above the piston 103. The water pressure overcomes the piston friction and possible residual gas pressure, pushing the piston 103 downward until it reaches the mechanical bottom dead center (which can be determined by the internal limiting structure of the housing or an external sensor).

[0045] (2) Inflation and Piston Upward Movement: After piston 103 reaches bottom dead center, the control system performs the following actions: closes exhaust valve solenoid valve 109, causing exhaust valve 105 to close under spring action, sealing the exhaust passage of combustion chamber 118; opens intake valve solenoid valve 113, causing intake valve 117 to open; a high-pressure air source (such as a compressed air cylinder or small air compressor) connected to intake valve 117 injects fresh air at a certain pressure into combustion chamber 118. The high-pressure gas enters the combustion chamber, pushing piston 103 to begin upward movement. This process, on the one hand, further squeezes out the residual exhaust gas from the previous cycle, and on the other hand, performs preliminary compression on the injected gas. At the same time, the upward movement of the piston also compresses the water above it, putting it in a pre-pressurized state.

[0046] (3) Detonation water injection; When the piston 103 moves upward to near top dead center (which can be estimated based on the stroke time or triggered by the position sensor), the control system executes the detonation sequence; the intake valve solenoid valve 113 is closed, the intake valve 117 is closed, and the combustion chamber 118 becomes a completely sealed space; the fuel injector 112 is controlled to open a very short time window to inject precisely measured atomized fuel into the combustion chamber 118; immediately afterward, the electronic igniter 110 is triggered to generate a high-energy electric spark, igniting the combustible mixture in the combustion chamber 118; the mixture rapidly detonates, and the temperature and pressure rise sharply (up to several MPa to tens of MPa), generating a huge expansion force that acts on the top surface of the piston 103; driven by this detonation pressure, the piston 103 moves rapidly upward (power stroke). Since the water chamber above it is filled with water and is basically incompressible, the piston's kinetic energy is immediately converted into the pressure energy of the water; at this time, the ball valve 119 is either automatically opened by the water pressure because it is designed as a one-way valve, or opened in advance / synchronously by the control system. High-pressure water jets are instantly ejected at high speed from the nozzle of the 120mm outlet pipe, forming a pulsed water jet with extremely strong impact. The jet velocity can reach tens to hundreds of meters per second, significantly increasing the effective range.

[0047] (4) Exhaust pressure relief: After one water injection, there is still high-temperature exhaust gas in the combustion chamber 118. The control system opens the exhaust valve solenoid valve 109, the exhaust valve 105 opens, the exhaust gas is discharged to the atmosphere, and the combustion chamber pressure drops. Then, the water injection process in step (1) can be restarted. The piston 103 returns to its original position under the action of water injection pressure or its own weight (depending on the installation angle), ready for the next working cycle.

[0048] The entire cycle can be completed in 1-3 seconds, achieving continuous or intermittent pulsed water spray.

[0049] IV. Assembly and Adjustment of the Device The pre-formed single-cylinder internal combustion pulse water spray mechanism 1 and the gunpowder-projection water cannon mechanism 2 are fixedly mounted side by side on the base 4. The base 4 is hinged to the top of the jack 3 via the angle adjustment seat 5, forming a support structure with an adjustable pitch angle. The height and level of the device are adjusted by the jack 3, and the pitch angle of the base 4 is adjusted by the angle adjustment seat 5, so as to achieve precise aiming at fire sources at different heights and distances.

[0050] V. Working Mode In practical applications, different modes can be selected according to the fire situation. 1. Single-pulse water spray mode; using only a single-cylinder internal combustion pulse water spray mechanism 1, it can accurately and intensely strike the key points of the fire source, and is suitable for scenarios that require concentrated fire extinguishing, such as oil pool fires and electrical equipment fires.

[0051] 2. Continuous pulse water spray mode: The working cycle of the pulse water spray mechanism is rapidly repeated to form a series of high-pressure water jets to suppress the fire line or large-area fire source.

[0052] 3. Water cannon projection mode; using gunpowder-projected water cannon mechanism 2, a large amount of water is projected in a parabolic trajectory to areas behind obstacles or areas that are difficult to spray directly, such as roof fires and forest crown fires.

[0053] 4. Combined attack mode; the two modes can be used alternately or simultaneously, combining long-range precision strikes and spray coverage, providing extremely high tactical flexibility.

[0054] The essence of this invention is the creation of a single-cylinder internal combustion engine that uses water as the transmission medium. It breaks away from the traditional technological paradigm that "internal combustion engines must output rotational mechanical energy," and through a unique structural design, perfectly combines the high power density and rapid response characteristics of an internal combustion engine with the fluid output requirements of a fire hose. This structural innovation enables the device to provide instantaneous fire extinguishing power far exceeding that of traditional fire-fighting equipment within the same volume and weight, offering a completely new and highly efficient solution for the field of specialized firefighting.

Any equivalent structural transformations, substitutions, or direct or indirect applications made based on the claims and description of the present invention are within the scope of patent protection of this invention.
