Technical Field
[0001] This invention belongs to the field of portable fire protection technology, and specifically relates to a fire extinguishing device for fire protection engineering. Background Technology
[0002] In fire protection engineering systems, fire extinguishing equipment is a core infrastructure for preventing and handling fire accidents, directly related to the safety of people's lives and the control of property losses. As a portable fire extinguishing device that can be directly operated by personnel, fire extinguishers are widely used in various scenarios such as buildings, industrial plants, transportation hubs, and commercial venues due to their compact structure, rapid start-up, and ease of operation. They are key equipment for initial fire suppression.
[0003] While existing fire extinguishers have played a vital role in extinguishing simple initial fires, they still have significant shortcomings in practical applications, making it difficult to meet the firefighting needs in complex scenarios. The physical exertion required for personnel to carry and move existing fire extinguishers is particularly pronounced in scenarios requiring long-distance movement, such as high-rise buildings and large factories, where poor portability is even more significant. Furthermore, operating a fire extinguisher requires continuous hand-holding and pressure control. For fires lasting for extended periods, prolonged holding can lead to arm pain and decreased strength, reducing firefighting efficiency and potentially causing safety hazards due to operational errors.

[0013] The fire extinguishing agent injection module is centered on an injection pipe, which is welded to the tank body. A sealing cap is installed on the top. Inside the pipe, from top to bottom, there is an open ring and a fixed cross. The sliding rod of the cross is connected to the top block coupling ring. The rod is fitted with a return spring, which provides strong sealing and leak prevention. The top block spring structure allows for unidirectional flow, which facilitates the injection of fire extinguishing agent and avoids backflow, thus improving the reliability of the injection operation.
[0014] In the above technical solution, the pressurization module further includes a support base, which is fixedly connected to one side of the fire extinguisher tank.

An outlet pipe is fixedly connected to the other end of the gas pressure tank. An electromagnetic switch valve is installed inside the outlet pipe. The control end of the electromagnetic switch valve is fixedly connected to the outer wall of the fire extinguisher tank.
[0015] The pressurization module uses a support base as its carrier, which is fixed to one side of the fire extinguisher tank. Inside, two metal blocks fix the gas pressure tank inside the tank. One end of the pressure tank is connected to the pressurization pipe of the external interface, and the other end is connected to the gas outlet pipe with an internal electromagnetic switch valve. The valve control end is located outside the tank. The pressure tank is fixed and stable, and the pressurization operation is convenient. The external electromagnetic switch valve can accurately control the pressure, effectively avoid accidental triggering, and improve the safety of pressurization operations.
[0016] In the above technical solution, the discharge module further includes a sealing pipe, the outside of which is fixedly connected to the inside of the fire extinguisher tank, an internal feed pipe is fixedly connected to the inside of the sealing pipe near the fire extinguisher tank, and a transport pipe is fixedly connected to one end of the sealing pipe near the outside, with a safety valve installed on the transport pipe.
[0017] The discharge module uses a sealing tube as its core component.

[0019] The fire extinguishing agent output module is centered on a pressurization pipe with a fixed support base at the bottom. It has a sealing flange a on the side, which can be detachably connected to flange b. The output hose is connected to flange b and is equipped with a fastening knob. The flange connection is convenient to install and disassemble, and has excellent sealing performance. The fastening knob enhances the connection stability and ensures smooth and leak-free output of the fire extinguishing agent.
[0020] In the above technical solution, a pressure nozzle is further fixedly connected to the top side of the fastening knob, and an adjustment ring is provided on the outside of the pressure nozzle. The adjustment ring is controlled to change the opening amplitude of the pressure nozzle, thereby changing the spray pattern.
[0021] The structure has a pressurized nozzle fixed to one side of the top of the fastening knob. An adjustment ring is installed on the outside of the nozzle. By operating the adjustment ring, the nozzle opening width can be changed, thereby realizing flexible switching of the spray pattern. It can adapt to the spraying needs of different fire extinguishing scenarios. The adjustment operation is simple and can accurately control the spray range and pattern of the extinguishing agent, improving the targeting and efficiency of fire extinguishing operations.
[0022] In the above technical solution, the auxiliary module further includes a metal hollow rod, a protective shell is fixedly connected to the top of the metal hollow rod, a small motor is installed inside the protective shell, the output end of the small motor passes through the protective shell and is fixedly connected to a destructive drill bit, an operation button is fixedly connected to the bottom of the small motor by a wire, the wire is deployed inside the metal hollow rod, and two retaining rings engage between the metal hollow rod and the output hose.
[0023] This auxiliary module is based on a hollow metal rod, with a small motor built into its top protective shell. The motor output is connected to a breaking drill bit, and the motor is connected to the operation button via a wire inside the rod. The rod and the output hose are fixed together by double snap rings, integrating obstacle breaking function. The wire has built-in anti-wear protection, and the snap rings secure the hose, which can quickly break through fire-fighting obstacles and improve the continuity and practicality of the operation.
[0024] Compared with the prior art, the present invention has the following beneficial effects: This invention offers several advantages: First, the addition of a fire extinguishing agent replenishment module allows for convenient refilling of the fire extinguishing agent without replacing the entire tank, enhancing the equipment's endurance and adapting it to long-term continuous firefighting scenarios. Second, the inclusion of an auxiliary breaching module addresses obstacles in the fire scene and enables coordinated breaching and firefighting operations via a locking ring, expanding the equipment's applicability in complex fire scenes (such as those with collapsed structures or enclosed doors and windows). Third, each module's robust fixing structure (such as a support base for fixing the gas pressure tank and multiple fixing straps for securing the tank) ensures operational stability, while a sealing design (such as an injection port sealing cap and a connecting flange seal) prevents fire extinguishing agent / pressurized gas leakage, further enhancing operational safety.
[0025] This invention provides a dual-mode mobility system: a push-rod propulsion system and a backpack carrying system. In the push-rod mode, the load-bearing frame with casters is moved by a push rod, eliminating the need for personnel to carry the load and making it suitable for long-distance transportation on flat terrain. In the backpack mode, adjustable shoulder straps and waist belts secure the device, while ergonomically designed protective foam reduces discomfort and is suitable for complex terrains where pushing is difficult (such as narrow passages and rugged roads). This significantly reduces physical exertion during movement and improves the device's accessibility in various scenarios.
[0026] This invention achieves multi-stage automation and labor-saving design: In the pressurization stage, gas is pre-injected into the gas pressure tank through a pressurization module. During fire extinguishing, only the electromagnetic switch valve needs to be controlled to pressurize the gas and drive the extinguishing agent, eliminating the need for manual pressurization. The fire extinguishing operation is controlled by the linkage of components such as the safety valve and the electromagnetic switch valve to deliver the extinguishing agent. With the help of the adjustable output hose and pressurization nozzle, personnel only need to hold the hose, aim it at the fire source, and adjust the spray parameters. There is no need to continuously apply pressure, reducing the intensity of operation, minimizing operational errors caused by arm pain and strength loss, and improving fire extinguishing efficiency and operational safety.

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] like Figures 1-11 The fire extinguishing equipment shown includes a fire extinguisher tank 1, which is integrally stamped from high-strength alloy steel and has excellent pressure resistance and explosion-proof performance. Inside, there is a storage chamber 5 for storing liquid or gaseous extinguishing agents. The inner wall of the storage chamber 5 is treated with an anti-corrosion and anti-rust coating to effectively prevent chemical reaction between the extinguishing agent and the tank wall and ensure the stability of the extinguishing agent storage. A transport module 2 is adapted to be installed at the bottom of the fire extinguisher tank 1, and a carrying module 4 is fitted and fixed on the side. A fixing module 3 for fixing the tank is assembled on the outward side of the carrying module 4.
[0031] The transport module 2 includes a bottom load-bearing frame 21, which is a rectangular steel structure frame welded from square steel, serving as the core load-bearing foundation of the transport module 2. Two push rods 22 are symmetrically fixed to one side of the bottom load-bearing frame 21. The push rods 22 are made of stainless steel round bars, with an ergonomically designed length for easy pushing and pulling by operators. Reinforcing beams 23 are welded and fixed to the adjacent sides of the two push rods 22, as well as between the push rods 22 and the bottom load-bearing frame 21. The reinforcing beams 23 are made of angle steel, significantly enhancing the connection rigidity between the push rods 22 and the bottom load-bearing frame 21, preventing structural deformation during pushing and pulling. A fixing frame 24 is welded and fixed to one side of the bottom load-bearing frame 21. The fixing frame 24 consists of two parallel circular steel bars. The ring structure has an inner diameter that matches the outer diameter of the auxiliary module 10, used for positioning and placing the auxiliary module 10. Two arc-shaped bearing blocks 25 are symmetrically fixed to the top of the bottom load-bearing frame 21. These arc-shaped bearing blocks 25 are made of rubber-coated metal cores, and their curvature perfectly matches the bottom outer diameter of the fire extinguisher tank 1. This ensures stable load-bearing of the tank and provides anti-slip and shock absorption, preventing wear between the tank and the frame during transportation. Four casters 26 are bolted to the bottom corners of the bottom load-bearing frame 21. These casters 26 are polyurethane wheels with brakes, offering flexible steering and strong load-bearing capacity, enabling rapid movement and fixed-point parking of the equipment. The four casters 26 are arranged in a rectangular pattern to ensure balanced force distribution during equipment transportation.
[0032] The carrying module 4 includes a back protection sponge 41, which is made of high-density flame-retardant sponge material and covered with fire-resistant and wear-resistant fabric. Its back side is fixed to the outside of the rectangular frame b34 by multiple rivets. The sponge conforms to the curve of the human back, effectively distributing the weight pressure of the fire extinguisher canister 1 and reducing discomfort when carrying it. Two fixed shoulder straps 42 are symmetrically sewn and fixed to both sides of the back protection sponge 41. The fixed shoulder straps 42 are made of double-layered wear-resistant nylon webbing, with a length adjustment buckle in the middle of the strap to accommodate operators of different heights. Side waist protection sponges 4 are also symmetrically fixed to both sides of the bottom of the back protection sponge 41. 3. The side waist protection sponge 43 and the back protection sponge 41 are made of the same material and fit the sides of the waist to further improve the comfort and stability of carrying. The front ends of the two fixed shoulder straps 42 are respectively fixedly connected to the male and female buckles of the chest buckle 44. By fastening the chest buckle 44, the shoulders can be quickly fixed to prevent the shoulder straps from slipping during carrying. The outer side of the side waist protection sponge 43 is respectively fixedly connected to the male and female buckles of the waist buckle 45. The two waist buckles 45 can be locked together, and the locking length is adjustable. By locking the waist buckle 45, the fire extinguisher canister 1 can be further fixed to prevent the canister from shaking significantly when carrying.
[0033] The fixing module 3 includes three fixing straps 31, which are made of flame-retardant nylon. The inner side of each strap has anti-slip textures, and they are evenly distributed in a ring around the outside of the fire extinguisher tank 1, allowing for multi-point fixing of the tank. A rectangular frame a32 is fixedly connected to the same end of each of the three fixing straps 31. The rectangular frame a32 is a rectangular structure welded from aluminum alloy and serves as the connecting carrier for the fixing module 3. Connecting buckles 33 are connected between the other side of the rectangular frame a32 and the other end of each fixing strap 31. The connecting buckles 33 are stainless steel snap-fit structures, featuring detachability and adjustability. The locking and unlocking of the fixing strap 31 can be quickly achieved by operating the connecting buckle 33, which facilitates the disassembly and maintenance of the fire extinguisher tank 1; a rectangular frame b34 is fixedly connected to one side of the rectangular frame a32 by bolts. The rectangular frame b34 and the rectangular frame a32 are made of the same material. Its outer side is used to connect and fix the back protective sponge 41 of the back-wearing module 4, so as to achieve a reliable connection between the fixing module 3 and the back-wearing module 4. The main body of the auxiliary module 10 is placed inside the two rings of the fixing frame 24, forming a detachable connection structure with the transport module 2, which is convenient for operators to carry with the equipment and can be quickly taken out when needed. A fire extinguishing agent input module 6 is fixedly installed on the bottom side of the fire extinguisher tank 1. The fire extinguishing agent input module 6 includes an injection pipe 61, which is integrally formed from stainless steel. Its outer wall is sealed and welded to the inner side wall of the fire extinguisher tank 1 by argon arc welding. The top end of the injection pipe 61 penetrates the wall of the fire extinguisher tank 1 and extends to the outside of the tank, while the bottom end is connected to the fire extinguishing agent storage chamber 5. A sealing cap 62 is threaded to the top end of the injection pipe 61. The inner wall of the sealing cap 62 is embedded with a fluororubber sealing gasket, which can achieve high-pressure sealing of the injection pipe 61 port to prevent the fire extinguishing agent from leaking from the fire extinguishing agent storage chamber 5. An open ring 63 is welded and fixed to the middle section of the injection pipe 61. The center of the open ring 63 has a circular through hole, and the inner wall of the through hole is polished. A fixing cross 64 is welded and fixed to the inside of the injection pipe 61 and below the open ring 63. The fixing cross 64 is a four-arm steel structure with a guide through hole in its center for sliding. The moving parts are limited and guided; a sliding rod 65 is slidably connected in the guide through hole of the fixed cross 64 to ensure smooth sliding without obvious shaking; a circular top block 66 is welded and fixed to the top of the sliding rod 65. The outer diameter of the circular top block 66 is adapted to the inner diameter of the center through hole of the open ring 63. The two adopt a conical coupling structure to achieve high-precision sealing fit; a return spring 67 is sleeved on the outside of the sliding rod 65. The upper end of the return spring 67 is welded and fixed to the bottom end face of the circular top block 66, and the lower end is welded and fixed to the top end face of the fixed cross 64. Under normal conditions, the return spring 67 is in a compressed state, pushing the circular top block 66 to fit tightly with the open ring 63, blocking the passage of the injection pipe 61. When the extinguishing agent is injected into the injection pipe 61, the pressure of the extinguishing agent overcomes the elastic force of the return spring 67, pushing the circular top block 66 to move down, opening the passage to realize the injection of the extinguishing agent. After the injection stops, the return spring 67 drives the circular top block 66 to reset, resealing the passage and preventing the extinguishing agent from flowing back. A pressurization module 7 is fixedly mounted on the side of the fire extinguisher tank 1, above the same side as the extinguishing agent input module 6. The pressurization module 7 includes a support base 71, which is a block structure made of aluminum alloy. One end face of the support base 71 is fastened to the outer wall of the fire extinguisher tank 1 by bolts, providing stable support for the components of the pressurization module 7. A gas pressure tank 72 is clamped and fixed in the internal groove of the support base 71 by two arc-shaped metal blocks. The gas pressure tank 72 is made of high-strength aluminum alloy and is placed inside the fire extinguisher tank 1 to store high-pressure nitrogen or carbon dioxide and other inert pressurized gases. A pressurization pipe 73 is welded and fixed to one end of the gas pressure tank 72. The other end penetrates the wall of the fire extinguisher tank 1, and its connection port is fixedly connected to the outside of the fire extinguisher tank 1 through a flange for connecting to an external gas source to realize the inflation and pressurization of the gas pressure tank 72; the other end of the gas pressure tank 72 is welded and fixed with an outlet pipe 74, and an electromagnetic switch valve 75 is embedded and fixed inside the outlet pipe 74. The electromagnetic switch valve 75 is a normally closed electromagnetic valve, and its valve body is placed inside the outlet pipe 74. The control end is fixedly connected to the outer wall of the fire extinguisher tank 1 by bolts, which facilitates the operator to perform electrical control operation. After the electromagnetic switch valve 75 is energized, the valve core opens, and the high-pressure gas enters the fire extinguishing agent storage chamber 5 through the outlet pipe 74 to pressurize the fire extinguishing agent in the chamber and provide power for the output of the fire extinguishing agent; A discharge module 8 is fixedly installed inside the fire extinguisher tank 1, between the extinguishing agent input module 6 and the pressurization module 7. The discharge module 8 includes a sealing pipe 81, which is a stainless steel high-pressure pipe. Its outer wall is welded and fixed to the inner side wall of the fire extinguisher tank 1, and both ends of the sealing pipe 81 are connected to the extinguishing agent storage chamber 5 and the external output passage, respectively. An internal feed pipe 82 is welded and fixed to the end of the sealing pipe 81 near the inside of the fire extinguisher tank 1. The port of the internal feed pipe 82 faces the bottom of the extinguishing agent storage chamber 5, which can ensure that the extinguishing agent in the extinguishing agent storage chamber 5 can be fully discharged. A transport pipe 83 is welded and fixed to the end of the sealing pipe 81 near the outside. The transport pipe 83 penetrates the fire extinguisher tank. The wall of the body 1 extends to the outside of the tank; a safety valve 84 is installed on the transport pipe 83. The safety valve 84 is a burst-type safety valve, and its rated burst pressure matches the design pressure resistance value of the fire extinguisher tank 1. When the pressure in the fire extinguishing agent storage chamber 5 is abnormally high, the safety valve 84 automatically opens to release pressure, preventing the tank from exploding and ensuring the safety of equipment use. A fire extinguishing agent output module 9 is fixedly installed between one side of the discharge module 8 and one side of the pressurization module 7. The fire extinguishing agent output module 9 includes a pressurization pipe 91, which is a stainless steel corrugated pipe. Its bottom is fastened to the top end face of the support base 71 through a flange, which can realize the mixing and pressurization of high-pressure gas and fire extinguishing agent; a sealing gas is welded and fixed to one end face of the pressurization pipe 91. The mating flange a92 has a graphite gasket embedded on its mating surface. A sealing flange b93 is detachably connected to one side of the sealing flange a92 via bolts. The sealing flange b93 has the same structural dimensions as the sealing flange a92, and the two can achieve a high-pressure seal after mating. The detachable connection facilitates future maintenance and replacement. An output hose 94 is clamped at one end of the sealing flange b93. The output hose 94 is made of wear-resistant and flame-retardant polyurethane material, possessing good flexibility and pressure resistance, allowing operators to flexibly adjust the spray direction during firefighting operations. A fastening knob 95 is fitted onto the outside of the output hose 94 near the sealing flange b93. The fastening knob 95 is a stainless steel locking structure. Rotating the fastening knob 95 can further clamp the output hose 94 to prevent it from falling off during high-pressure spraying. A pressurizing nozzle 96 is welded and fixed to the top side of the fastening knob 95. The pressurizing nozzle 96 has a flow guiding channel inside, which can accelerate and pressurize the extinguishing agent. An adjusting ring 97 is sleeved on the outside of the pressurizing nozzle 96. The adjusting ring 97 is threadedly connected to the pressurizing nozzle 96. Rotating the adjusting ring 97 can change the opening width of the pressurizing nozzle 96, thereby realizing the switching of the extinguishing agent spray form. When the opening width is small, the spray form is a columnar jet, which is suitable for long-distance fire extinguishing. When the opening width is large, the spray form is a mist jet, which is suitable for large-area coverage fire extinguishing. An auxiliary module 10 is fixedly installed on one side of the transport module 2. The auxiliary module 10 includes a hollow metal rod 101, which is a hollow structure made of stainless steel. Its bottom end is fixedly connected to the fixing frame 24 of the transport module 2 by bolts. A protective shell 102 is welded and fixed to the top of the hollow metal rod 101. The protective shell 102 is a shell structure made of flame-retardant ABS material, which has good impact resistance and protective performance. A small motor 103 is fixedly installed inside the protective shell 102 by bolts. The small motor 103 is a DC high-speed motor, which has the characteristics of small size and high torque. The output end of the small motor 103 passes through the bottom wall of the protective shell 102 and is fixedly connected to a destructive drill bit 104 through a coupling. The destructive drill bit 104 is made of cemented carbide. The end of the small motor 103 is equipped with a spiral cutting edge, which can be used to break through glass doors and windows, wooden obstacles, etc., so that operators can quickly open up fire extinguishing channels. The bottom of the small motor 103 is electrically connected to the operation button 105 through a wire. The wire is deployed in the internal cavity of the metal hollow rod 101 throughout, which can effectively prevent the wire from being worn or torn during operation. The operation button 105 is fixed on the bottom side wall of the metal hollow rod 101, so that the operator can control the start and stop of the small motor 103 with one hand. The metal hollow rod 101 and the output hose 94 are locked together by two semi-circular retaining rings 98. The retaining rings 98 are made of stainless steel and are locked with bolts to fix the output hose 94 to the metal hollow rod 101, preventing the output hose 94 from shaking at will and improving the convenience of operation.
[0034] Working principle: Pushing the push rod 22 of the transport module 2 moves the bottom load-bearing frame 21, causing the casters 26 at the four corners of the bottom of the bottom load-bearing frame 21 to rotate, thereby moving the fire extinguisher tank 1 placed on the arc-shaped support block 25 at the top of the bottom load-bearing frame 21. During the movement, the stability between the push rod 22 and the bottom load-bearing frame 21 can be enhanced by the reinforcement beam 23. At the same time, the auxiliary module 10 moves synchronously with the movement of the fixed frame 24 until the equipment is pushed to a suitable position at the fire scene. If the terrain makes it inconvenient to move the device, the back-wearing module 4 can be adjusted. First, pull the fixed shoulder strap 42 to adjust it to a suitable length, then fit the back protective sponge 41 against the back. Next, fasten the chest buckle 44 between the two fixed shoulder straps 42, and then pull the waist buckle 45 on one side of the side waist protective sponge 43 so that the two waist buckles 45 are locked together. The fire extinguisher tank 1 is then firmly fixed to the back by the three fixed straps 31 of the fixed module 3, thus realizing the back-wearing movement of the device.
[0035] Upon arrival at the scene, if the extinguishing agent in the fire extinguisher tank 1 is insufficient, it needs to be replenished. In this case, first rotate the sealing cover 62 of the extinguishing agent input module 6 to separate the sealing cover 62 from the injection pipe 61. Then, use an external injection tool to push the circular top block 66, so that the circular top block 66 drives the sliding rod 65 to slide inside the fixed cross 64. At the same time, the circular top block 66 compresses the return spring 67 at its bottom, and the circular top block 66 separates from the hole of the perforated ring 63. The extinguishing agent is injected into the storage cavity 5 of the fire extinguisher tank 1 through the injection pipe 61. After the injection is completed, remove the external injection tool, and the return spring 67 restores its elastic deformation, causing the circular top block 66 to slide upward and recouple with the hole of the perforated ring 63. Finally, rotate the sealing cover 62 to make it threadedly connected and sealed with the injection pipe 61.
[0036] After the extinguishing agent is replenished, pressurization preparation is carried out. Pressurized gas is injected into the gas pressure tank 72 through the pressurization pipe 73 of the pressurization module 7. The gas pressure tank 72 remains stable under the fixing action of the two metal blocks of the support base 71. After pressurization to the specified pressure, the gas injection is stopped.
[0037] When initiating the fire extinguishing operation, first open the safety valve 84 of the discharge module 8 to release the blockage of the transport pipe 83. Then, control the solenoid switch valve 75 of the pressurization module 7 to open the gas outlet pipe 74. The pressurized gas in the gas pressure tank 72 enters the storage chamber 5 of the fire extinguisher tank 1 through the gas outlet pipe 74, applying pressure to the extinguishing agent in the storage chamber 5. The pressure pushes the extinguishing agent into the internal feed pipe 82 of the discharge module 8, thereby causing the extinguishing agent to flow in the sealed pipe 81. Subsequently, the extinguishing agent enters the fire extinguishing tank through the transport pipe 83. The extinguishing agent enters the pressurization pipe 91 of the agent output module 9 and flows through the joint between the sealing flange a92 and the sealing flange b93 to the output hose 94. The fastening knob 95 on the outside of the output hose 94 is rotated to adjust the conduction state of the output hose 94. Then, the output hose 94 is held and aimed at the fire source. The adjusting ring 97 on the outside of the pressurization nozzle 96 is rotated to control the opening width of the pressurization nozzle 96, thereby changing the spray pattern of the extinguishing agent and realizing fire extinguishing operations in different fire scenarios.
[0038] If obstacles obstruct firefighting operations, the auxiliary module 10 placed inside the two rings of the fixed frame 24 can be removed. Holding the hollow metal rod 101, the breaking drill bit 104 on one side of the protective shell 102 is aligned with the obstacle. The operation button 105 on the hollow metal rod 101 is pressed, and a signal is transmitted through the wire to start the small motor 103 inside the protective shell 102. The output end of the small motor 103 drives the breaking drill bit 104 to rotate at high speed. The rotating breaking drill bit 104 is used to break down the obstacle. During the breaking process, the output hose 94 can be fixed to the hollow metal rod 101 by the two retaining rings 98 between the hollow metal rod 101 and the output hose 94, realizing the coordinated operation of breaking down and extinguishing the fire. If the firefighting position needs to be adjusted during the firefighting process, the push rod 22 can be pushed again to rotate the universal wheel 26 to move the equipment, or the body position can be adjusted while maintaining the back-wearing position to ensure that the firefighting operation is carried out continuously and efficiently.
