Technical Field

[0001] This invention belongs to the field of propellant tank transfer technology, specifically, it relates to a transport device for a vertical propellant tank. Background Technology

[0002] Liquid propellants (such as hydrazine and nitro oxidizers) are flammable, explosive, highly toxic, and highly corrosive. Currently, the transportation of propellants relies heavily on hazardous materials transport vehicles and propellant storage tanks, moving between filling, storage, and use sites. Safety during transportation is the core and critical factor in the entire process.

[0003] Existing vertical propellant tank transport devices have limited functionality and are typically equipped only with traditional strapping-type fixing structures, which are not only inconvenient to operate but also have poor stability during transportation.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

A multi-dimensional constraint system for the propellant storage tank is installed in the propellant storage tank storage area to limit and fix the propellant storage tank after it has been positioned in the propellant storage tank storage area.

[0007] In some embodiments, the heavy-duty lifting and positioning system includes: The slide is fixedly connected to the top of the housing; The suspension assembly is slidably connected to the slide rail and configured to lift the propellant tank.

[0008] In some embodiments, the suspension assembly includes an explosion-proof hand-operated hoist trolley and an explosion-proof manual rail hoist.

[0009] In some embodiments, the tank multidimensional constraint system includes: A bottom fixing component is fixedly connected to the bottom of the housing and configured to fix the bottom of the propellant storage tank; A circumferential fixing assembly is fixedly connected to the bottom and sides of the housing and configured to fix the circumferential position of the propellant tank.

[0010] In some embodiments, the bottom of the propellant storage tank area is provided with a plurality of C-shaped guide rails, which are arranged in a crisscross pattern. The openings of the C-shaped guide rails face the top of the tank, and the intersection of two C-shaped guide rails is configured as the center position of the propellant storage tank. The bottom fixing assembly includes multiple bottom fixing structures, each configured to fix the base of the propellant tank to the C-shaped guide rail: The bottom fixing structure includes: T-bolt, wherein the T-head of the T-bolt is configured to extend into the opening of the C-shaped guide rail in a first direction and be limited by the opening of the C-shaped guide rail in a second direction, wherein the first direction and the second direction intersect. The pressure plate is fixedly connected to the T-bolt. One side of the pressure plate is pressed onto the base of the propellant storage tank, and the other side is sandwiched between the pressure plate and the C-shaped guide rail, so that the pressure plate is in a horizontal state.

[0011] In some embodiments, the pads are configured with various structures of different heights to accommodate the bases of propellant tanks of different heights when stacked. Some of the pads have protrusions, and some have recesses. Multiple pads are stacked by the cooperation of the protrusions and the recesses.

[0012] In some embodiments, the circumferential fixing assembly includes a plurality of U-shaped fixing rings and a plurality of explosion-proof tensioning devices that are connected one-to-one with the plurality of U-shaped fixing rings; The plurality of U-shaped fixing rings are distributed at the bottom and sides of the box.

[0013] In some embodiments, the container also includes an equipment placement area, which is isolated from the propellant storage tank area. The equipment placement area is configured to house power equipment and temperature and humidity control equipment.

[0014] In some embodiments, the propellant storage tank area is also equipped with an emergency response and disposal system; The emergency response system includes a portable propellant gas concentration monitor, a handheld decontamination device, and a fire extinguisher.

[0015] In some embodiments, the bottom of the housing is provided with a forklift hole adapted to the operating requirements of a forklift for hoisting the transport device onto the transport vehicle skeleton.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0017] 1. The vertical propellant tank transportation device provided by the present invention, by setting up a heavy-duty lifting and positioning system and a multi-dimensional constraint system for the tank in the propellant tank storage area of ​​the transportation device, respectively realizes the lifting and positioning operation and precise limiting and fixing of the propellant tank, thereby significantly improving the stability and safety of the propellant tank transportation process, while simplifying the operation process of loading and unloading the tank, improving the operation efficiency, reducing the safety hazards in the high-risk propellant transfer process, and ensuring the safety of personnel and the environment.

[0018] 2. The vertical propellant tank transport device provided by this invention, through the coordinated operation of an explosion-proof hand-operated hoist trolley and an explosion-proof manual guide rail hoist, enables the propellant tank to be raised and lowered in the storage area and moved horizontally for positioning. This allows for precise lifting and positioning of the tank. Moreover, the explosion-proof components are adapted to the flammable, explosive, and highly toxic characteristics of propellants, thus avoiding the risk of ignition during operation and ensuring operational safety. It eliminates the need for external large-scale hoisting equipment, simplifies the loading and unloading process, and reduces site adaptability requirements. Furthermore, the precise and controllable lifting and horizontal movement reduces the risk of collisions and tilting during tank positioning, protecting the tank body and sealing structure. The manual operation mode is stable and reliable, unaffected by power interruptions, and improves the operational fault tolerance rate under extreme conditions.

[0019] 3. The vertical propellant tank transportation device provided by this invention constructs a multi-dimensional constraint system by coordinating the bottom and circumference of the propellant tank. This effectively limits the sliding, tilting, and shaking of the vertical tank throughout the transportation process and under special conditions such as emergency braking and road bumps, fundamentally avoiding risks such as tank collisions, overturning, and seal failures. Moreover, the multi-dimensional constraint structure covers the key stress-bearing parts of the tank, significantly improving the stability compared to traditional single-binding methods, and adapting to transportation needs under complex road conditions. The coordinated force of the bottom and circumference constraints can evenly disperse the inertial impact force during transportation, reducing stress damage to the tank body and interfaces, and extending the service life of the equipment. In addition, considering the flammable, explosive, and highly toxic characteristics of propellants, the multi-dimensional constraint can effectively prevent catastrophic accidents such as leakage and diffusion caused by tank displacement, comprehensively ensuring the safety of personnel, equipment, and the surrounding environment.

[0020] 4. The vertical propellant storage tank transportation device provided by the present invention uses a combination structure of C-shaped guide rails, T-bolts, pressure plates and pads to fix the bottom of the propellant storage tank frame. The longitudinal and transverse arrangement of the C-shaped guide rails provides positioning for the fixing points. The matching structure of the T-bolts and C-shaped guide rails can quickly complete positioning and limiting. The combination of pressure plates and pads achieves stable pressing. The fixing and disassembly of the overall structure is convenient and efficient, which can significantly shorten the preparation and finishing time of the transfer operation.

[0021] 5. The vertical propellant storage tank transportation device provided by this invention, by isolating a storage area within the tank for the power equipment and temperature and humidity control equipment, not only ensures the constant temperature and humidity environment of the propellant storage tank storage area, protecting the chemical stability of highly sensitive propellants (such as hydrazine), and preventing changes in propellant performance or safety hazards due to temperature and humidity fluctuations; it also achieves physical isolation between the power equipment and the propellant storage tank storage area, preventing dangerous factors such as sparks and high temperatures generated during the operation of the power equipment from directly contacting the propellant, further improving the safety protection level during transportation; at the same time, the independent equipment storage area facilitates centralized management, inspection, and maintenance of the power equipment and temperature and humidity control equipment, avoiding interference with the propellant storage tank during equipment operation and maintenance, and also improving the overall ease of operation and maintenance of the device.

[0025] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] As mentioned above, existing vertical propellant tank transport devices suffer from limited functionality, inconvenient operation, and poor stability during transport. Therefore, this invention provides a transport device for vertical propellant tanks, including a housing with a propellant tank storage area. The storage area is equipped with a heavy-duty lifting and positioning system and a multi-dimensional tank restraint system. The heavy-duty lifting and positioning system is used for lifting and positioning the propellant tank within the storage area, while the multi-dimensional tank restraint system is used to limit and fix the propellant tank after it has been positioned within the storage area. This solution significantly improves the stability and safety of propellant tank transport, simplifies loading and unloading procedures, increases operational efficiency, reduces safety hazards during high-risk propellant transfers, and ensures personnel and environmental safety.

[0030] Figures 1 to 10 A partial structural schematic diagram of a transport device 100 for a vertical propellant storage tank 200 provided according to an exemplary embodiment of the present invention is shown.

[0031] like Figures 1 to 10 As shown, the transport device 100 of the vertical propellant storage tank 200 uses an approximately 20-foot insulated container 10 as a carrier and adopts a partitioned isolation design, dividing it into a front-end equipment placement area 17 and a rear-end propellant storage tank storage area 18, to achieve physical isolation between the equipment and the storage tank, effectively avoid interference from equipment operation to the storage tank, and improve transportation safety.

[0032] like Figure 1 As shown, the box 10 is composed of a carrier frame and six panels (front, rear, left, right, bottom, and top) assembled together. Each panel is tightly fitted to the frame, ensuring the overall structural strength of the box 10. For example, Figure 3As shown, the base plate 11 has pre-set forklift holes 111, precisely matching forklift operation specifications, enabling rapid forklift transfer of the transport device 100 and improving loading and unloading efficiency. The outer corners of the box body 10 are equipped with eight standard container corner fittings to adapt to lifting operation requirements, achieving both forklift and lifting loading / unloading modes and enhancing the flexibility of transportation and handling. This device is compatible with various transportation scenarios such as road, rail, and sea transport, and can be directly secured using standard reinforcement and binding equipment without the need for additional custom-made fasteners, significantly reducing the operational difficulty and cost of cross-modal transport transfers.

[0033] The tank 10 integrates five core systems: a multi-dimensional constraint system 20 for the storage tank, an emergency response and disposal system 30, an environmental parameter centralized control system 40, a silent diesel generator system 50, and a heavy-duty lifting and positioning system 60. Through system collaboration, the vertical propellant storage tank 200 achieves integrated functions of safe transportation and temporary storage without the need for additional auxiliary equipment, greatly improving the integration level and applicability of the device.

[0034] It should be noted that the propellant storage tank 200 of the present invention includes a storage tank body 201 and a storage tank frame 202 fixed on the outside. The storage tank frame 202 is a rigid frame structure composed of multiple horizontal beams and vertical beams. The storage tank body 201 is firmly fixed inside the storage tank frame 202. Based on this, the operation objects of the heavy-duty lifting and positioning system 60 and the storage tank multi-dimensional constraint system 20 are both the storage tank frame 202, and there is no need to directly contact the storage tank body 201. Mechanical damage to the storage tank body 201 can be avoided from the operation level.

[0035] The technical solutions for each core system are described in detail below. The silent diesel generator system 50 includes a diesel generator 51 and supporting wiring. Its core function is to provide stable power for the operation of the environmental parameter centralized control system 40, ensuring the continuity and reliability of environmental control. The diesel generator 51 is fixed to the lower part of the equipment placement area 17 by a vibration damping bracket. The vibration damping bracket can effectively absorb the vibration generated by the generator operation, reduce the impact of vibration on the structure of the housing 10 and other equipment, and reduce vibration noise to meet the silent design requirements of the device.

[0036] The environmental parameter centralized control system 40 includes a temperature and humidity control device 41, an air distribution duct 42, a temperature and humidity display 43, and supporting wiring. The temperature and humidity control device 41 is connected to a diesel generator 51, which provides power.

[0037] The temperature and humidity control equipment 41 includes an explosion-proof constant temperature and humidity machine 411 and an explosion-proof electrical control cabinet 412. Both are fixed to the upper part of the equipment placement area 17 (above the diesel generator 51) via shock-absorbing brackets. The upper and lower layer layout design makes efficient use of the space in the equipment placement area 17, improving space utilization. The explosion-proof electrical control cabinet 412 is responsible for the operation and control of the explosion-proof constant temperature and humidity machine 411. It can precisely control the temperature in the propellant storage tank area 18 within the range of 10℃ to 25℃ and the humidity within the range of 45% to 65%. This temperature and humidity range completely covers the environmental requirements for propellant storage, effectively ensuring the stability of the propellant and preventing changes in propellant performance due to excessive environmental parameters.

[0038] A ventilation duct 42 is installed in the propellant storage tank area 18. Evenly distributed exhaust vents are provided on the side walls of the duct. Circulating airflow meeting temperature and humidity requirements is evenly distributed to every corner of the storage area through the ventilation duct, achieving overall temperature and humidity balance and preventing localized temperature and humidity differences from affecting the storage tank. A temperature and humidity display 43 is installed in a prominent position in the propellant storage tank area 18, providing real-time and intuitive display of internal temperature and humidity data for easy monitoring by operators.

[0039] Optionally, multiple temperature and humidity displays 43 can be added to the propellant storage tank area 18 to achieve multi-point monitoring, further improving the accuracy of temperature and humidity monitoring and avoiding the problem of missing temperature and humidity differences in different areas. In addition, the explosion-proof electrical control cabinet 412 is equipped with an external mains power interface, which can quickly switch to mains power supply mode in special working conditions such as insufficient diesel fuel, ensuring uninterrupted operation of the environmental parameter centralized control system 40 and improving system reliability and redundancy.

[0040] It should be noted that the silent diesel generator system 50 and the environmental parameter centralized control system 40 are both equipped with sufficient maintenance space, which facilitates the disassembly and maintenance of components such as generator batteries by operators, reducing maintenance difficulty and labor costs. At the same time, the exhaust port of the diesel generator 51 is precisely oriented towards an open area to avoid damage to operators from the high-temperature gas or exhaust gas emitted from the exhaust port, thereby improving the safety of equipment operation.

[0041] The heavy-duty lifting and positioning system 60 can be configured with two sets, such as Figure 4 As shown, a single unit has a maximum load capacity of 5 tons, which can stably support the weight of the propellant storage tank 200 and ensure the safety of the lifting and positioning process. The system is mainly used for lifting and accurately positioning the propellant storage tank 200 in the storage area. After positioning, it is fixed by the tank multi-dimensional constraint system 20, forming a complete "lifting-positioning-fixing" operation process, improving the standardization and efficiency of operation.

[0042] In some embodiments, the heavy-duty lifting and positioning system 60 includes a slide rail 61 and a suspension assembly 62. The slide rail 61 is fixedly connected to the top of the housing 10; the suspension assembly 62 is slidably connected to the slide rail 61 and is configured to lift the propellant tank 200, thereby achieving flexible adjustment of the suspension direction and precisely adapting to the lifting requirements of the tank.

[0043] As an example, the suspension assembly 62 includes an explosion-proof hand-operated hoist trolley 621 and an explosion-proof manual rail hoist 622. The explosion-proof design is suitable for the transportation scenarios where propellants are flammable and explosive, avoiding the safety risks caused by electrical sparks from the equipment selection; the manual operation mode does not require an additional power source, reducing the probability of equipment failure and improving operational controllability.

[0044] The multi-dimensional restraint system 20 is used for bottom and circumferential double-limiting fixation of the propellant storage tank 200 after it is in place. Through bidirectional restraint, it can effectively limit the sliding and shaking of the storage tank during transportation (such as emergency braking and bumpy road sections), and prevent the storage tank from colliding with the container 10 or tipping over, thus ensuring transportation safety from a structural perspective.

[0045] In some implementations, such as Figures 8 to 10 As shown, the multidimensional restraint system 20 of the storage tank includes a bottom fixing component and a circumferential fixing component 22. The bottom fixing component is fixedly connected to the bottom of the tank body 10 and is configured to fix the bottom of the propellant storage tank 200. The circumferential fixing component 22 is fixedly connected to the bottom and sides of the tank body 10 and is configured to fix the circumferential position of the propellant storage tank 200. The two work together to form an all-round restraint system.

[0046] As an example, the bottom of the propellant storage tank storage area 18 is provided with several C-shaped guide rails 23, which are arranged in a crisscross pattern. The openings of the C-shaped guide rails 23 face the top of the housing 10, and the intersection of two C-shaped guide rails 23 is configured as the fixed position of the propellant storage tank 200. The bottom fixing assembly includes multiple bottom fixing structures 21, each of which is configured to fix the tank frame 202 of the propellant storage tank 200 to the C-shaped guide rails 23.

[0047] It should be noted that the number and arrangement of the C-shaped guide rails 23 can be flexibly adapted to the specifications of the propellant storage tank 200. For example, four C-shaped guide rails 23 can be set on the base plate 11 in a "one horizontal and three vertical" configuration, that is, one horizontal C-shaped guide rail 23 and three vertical C-shaped guide rails 23 are set on the base plate 11, which intersect to form three independent tank fixing points at the front, middle, and rear. Figures 5 to 7As shown, this layout scheme can adapt to the storage needs of various sizes of storage tanks: when transporting propellant storage tanks 200 with specifications of 1700mm×1700mm or 1500mm×1500mm, two storage tanks can be fixed side by side using two fixed points at the front and rear; when transporting propellant storage tanks 200 with specifications of 850mm×850mm, three storage tanks can be fixed in an orderly manner using three fixed points at the front, middle and rear.

[0048] Optionally, the bottom fixing structure 21 includes a T-bolt 211 and a pressure plate 212. The T-head 2111 of the T-bolt 211 is configured to extend into the opening of the C-shaped guide rail 23 in a first direction and is limited by the opening of the C-shaped guide rail 23 in a second direction (intersecting with the first direction), thereby realizing the rapid positioning and anti-loosening of the T-bolt 211. The pressure plate 212 is fixedly connected to the T-bolt 211. One side of the pressure plate 212 is pressed onto the tank frame 202 of the propellant storage tank 200, and a pad 214 is sandwiched between the other side and the C-shaped guide rail 23, so that the pressure plate 212 is in a horizontal state.

[0049] The pad 214 can be configured with various structures of different heights, and can be stacked and assembled to fit propellant tanks 200 and tank frames 202 of different heights, thereby improving the versatility of the device. Some pads 214 are provided with bosses and some are provided with concave holes. When stacked, the bosses and concave holes cooperate to achieve precise positioning, prevent the pads 214 from sliding during transportation, and ensure the stability of the pressure plate 212.

[0050] In the above scheme, the longitudinal and transverse layout of the C-shaped guide rail 23 allows for flexible adjustment of the fixing points. Combined with pads 214 of different heights, it can accommodate propellant tanks 200 of different diameters and tank frames 202 of different heights, significantly improving the device's adaptability to various tank sizes without requiring custom-designed fixing structures for different tanks. The limiting structure of the T-bolt 211 and the horizontal clamping method of the pressure plate 212 evenly distribute the weight of the tank and the inertial force during transportation to the bottom of the housing 10, preventing tank displacement or structural damage caused by excessive local stress. The mating structure of the boss and concave hole of the pad 214 prevents the stacked pads 214 from sliding during transportation, ensuring that the pressure plate 212 remains horizontally clamped. The entire fixing structure has no complex power components, allowing for manual installation and disassembly, lowering the technical threshold for operation and reducing the probability of malfunctions and maintenance. Furthermore, each component can be replaced individually, eliminating the need for complete replacement in case of wear or damage, thus reducing operating costs. This purely mechanical, fixed structure does not generate electrical sparks and is perfectly suited for transporting propellants that are flammable, explosive, and highly toxic, thus structurally avoiding additional safety risks.

[0051] The circumferential fixing component 22 includes several U-shaped fixing rings 221 and corresponding explosion-proof tensioning devices (not shown). The U-shaped fixing rings 221 are distributed on the top and sides of the tank 10 to form multi-point circumferential constraints. The explosion-proof tensioning devices (such as explosion-proof ropes) connect the U-shaped fixing rings 221 to the angle fixing rings 203 on the tank frame 202. The tensioning action achieves stable circumferential constraints on the tank, and the explosion-proof design further ensures the safety of the constraint process.

[0052] It should be noted that multiple angle-shaped fixing rings 203 are provided on the tank frame 202 outside the tank body 201 for connection with the explosion-proof tensioning device. For example, as shown... Figure 8 As mentioned above, an angled fixing ring 203 is set at the connection position between the crossbeam and the longitudinal beam to improve the load-bearing capacity of the connection structure.

[0053] The emergency response system 30 includes a portable propellant gas concentration monitor (not shown), a handheld decontamination device 31, and a fire extinguisher 32, forming a complete emergency system of "monitoring-response-protection" to improve the ability to handle emergencies. Both the portable propellant gas concentration monitor and the handheld decontamination device 31 are equipped with both hydrazine-based and nitro oxidizer-based models, allowing for precise selection based on the type of propellant being transported, thus improving the targeted nature of emergency response. The portable propellant gas concentration monitor casing is placed in the vehicle's cab for easy access and monitoring by operators.

[0054] Four portable decontamination devices 31 are installed and fixed to the lower part of the front side panel 13 and the rear side panel 14 by quick-opening fixed brackets. Fire extinguishers 32 are fixed to the bottom of the door on the right side panel 16 by brackets. All emergency equipment is arranged in a convenient location and can be quickly retrieved in an emergency, shortening the emergency response time.

[0055] The specific emergency procedure of the system is as follows: the internal propellant concentration is monitored in real time by a portable propellant gas concentration monitor to accurately determine whether a leak has occurred; if a leak occurs, the portable decontamination device 31 can be taken immediately, the nozzle can be aimed at the leak point, and the liquid outlet valve can be opened slowly to complete the emergency treatment; after the treatment is completed, the inside of the device can be cleaned with clean water, and the cleaning waste liquid can be directly discharged through the pre-set drain ports at the four corners of the bottom plate 11 to avoid waste liquid residue causing secondary pollution.

[0056] The following details the installation positions of the 10 panels in the enclosure and the aforementioned equipment, clarifying the functional layout of each area and improving the ease of operation and maintenance of the device: 1. Base plate 11: as shown Figure 8As shown, the base plate 11 structure includes a bottom frame 113, a bottom crossbeam 114, a corrugated base plate 115, and an inner base plate 116. Each of the left and right sides of the base plate 11 is equipped with 4-8 U-shaped fixing rings 221, which connect to the angled fixing rings 203 on the tank frame 202, serving as fixing points for circumferential constraints. Several C-shaped guide rails 23 are fixed to the base plate 11 with their openings facing upwards, forming a bottom fixing foundation. After the propellant tank 200 is pushed in and precisely positioned, the tank frame 202 is fixed to the C-shaped guide rails 23 via the bottom fixing structure 21, restricting the horizontal movement of the tank on the base plate 11 and ensuring bottom stability. In addition, the base plate 11 is equipped with 8 tank container base plate fixing devices 24 to restrict the movement of the propellant tank 200, which, together with the U-shaped fixing rings 221 and explosion-proof tensioning devices, constitute a multi-dimensional constraint operation system for the tank. Optionally, a buffer rubber pad 112 is laid on top of the base plate 11. Through the elastic buffering effect of the rubber, the impact damage caused by hard contact between the propellant storage tank 200 and the base plate 11 during transportation is avoided. At the same time, it can absorb the vibration caused by transportation bumps, further ensuring the safety of the storage tank and the internal propellant.

[0057] 2. Top plate 12: as Figure 1 As shown, an H-shaped slide rail 61 is provided on each of the left and right sides of the top plate 12. The slide rail 61 extends in the front-to-back direction. Each slide rail 61 is equipped with an explosion-proof hand-operated hoist trolley 621 and an explosion-proof manual guide rail hoist 622. Combined with the special lifting strap for the storage tank, the storage tank can be lifted and moved back and forth, ensuring accurate positioning. A ventilation channel 42 is arranged in the middle of the top plate 12. The ventilation channel 42 extends in the front-to-back direction and has exhaust vents on both sides, which can evenly deliver the circulating air with the required temperature and humidity to the entire storage area, ensuring the internal temperature and humidity are balanced.

[0058] 3. Right side panel 16: Two side-opening doors 161 are arranged to serve as passages for the propellant storage tank 200 to enter and exit the storage area. The large opening design facilitates the rapid entry and exit of the storage tank. Each side-opening door 161 is equipped with two quick-opening fire extinguisher 32 brackets for fixing the fire extinguisher 32. The quick-opening design allows for rapid access to the fire extinguisher 32 in an emergency. The upper end of the right side panel 16 is equipped with 4 to 8 U-shaped fixing rings 221, which are connected to the angle fixing rings 203 on the tank frame 202 as circumferential fixing points to improve the stability of circumferential constraints.

[0060] 5. Front panel 13: An air inlet 131 and an air outlet 132 are opened at the bottom and top of the roughly central position. The air inlet 131 can be equipped with a filter to filter impurities in the circulating airflow. The air outlet 132 is connected to the air distribution channel 42 to form a complete airflow circulation channel to ensure the temperature and humidity control effect. Two portable decontamination devices 31 are equipped near the door 161 of the right side panel 16 on the front panel 13. They are fixed by quick-opening brackets for easy access in emergency situations and to improve emergency response efficiency.

[0061] 6. Rear panel 14: Equipped with two portable decontamination devices 31, which together with the decontamination device on the front panel 13 form a full coverage, ensuring that any leaks in any location in the storage area can be dealt with quickly; a toolbox 33 is set on the upper part of the decontamination device, which stores commonly used tools of the bottom fixing device. The height of the toolbox 33 is ergonomically designed, making it easy for operators to open the box to take out and put in tools, thus improving the convenience of maintenance operations.

[0062] The following provides a detailed description of the process for securing the propellant storage tank 200 within the transport device 100, clarifying the operating steps and key precautions to ensure the standardization and safety of the securing operation: Step 1: Device Positioning and Environmental Pretreatment. Using a forklift, the transport device 100 is lifted onto the transport vehicle frame through the forklift holes 111 on the base plate 11. It is then secured using the corner brackets 10 of the box body (or directly positioned by crane lifting), ensuring the stability of the transport device 100 on the transport vehicle. The diesel generator 51 is started to supply power to the explosion-proof temperature and humidity control unit 411. The target temperature and humidity are set through the explosion-proof electrical control cabinet 412, and the data on the temperature and humidity display 43 is monitored in real time. Once the temperature and humidity in the storage area reach the preset standards, the device proceeds to the propellant storage tank 200 for transfer.

[0063] Step 2: Tank Lifting and Precise Positioning. Using specialized slings, connect both sides of the tank frame 202 to the hooks of the explosion-proof manual guide rail hoist 622. Pull the hoist chain to lift the propellant tank 200, and pull the chain of the manual hoist trolley to move the propellant tank 200 back and forth. Through the coordinated operation of lifting and translating, the propellant tank 200 is precisely adjusted to the preset fixed position (i.e., the intersection of the two C-shaped guide rails 23), completing the positioning.

[0064] Step 3: Double fixation and locking. (For example...) Figure 9 and Figure 10 As shown, after the propellant storage tank 200 is in place, the bottom is fixed first in four directions: front, back, left, and right. Rotate the T-head 2111 of the T-bolt 211 to the narrow end, pass it through the opening of the C-shaped guide rail 23, and then rotate the T-head 2111 to limit it by the guide rail opening. Stack the pad 214 on the C-shaped guide rail 23 until it is flush with the bottom of the storage tank frame 202. Place the inverted L-shaped pressure plate 212 so that one end of the pressure plate 212 covers the storage tank frame 202 and the other end covers the pad 214. The middle hole of the pressure plate 212 passes through the screw 2112 of the T-bolt 211. Tighten the nut 213 for pre-tightening. At this time, the folded edge of the L-shaped pressure plate 212 covers the outside of the pad 214 to ensure connection stability. After the bottom fixing structures 21 in all four directions have been pre-tightened, tighten all nuts 213 to achieve a stable fixation of the bottom of the storage tank. After the bottom is fixed, circumferential fixing is performed: the angled fixing ring 203 on the tank frame 202 is tightened and fixed to the U-shaped fixing ring 221 on the bottom plate 11, the left side plate 15 and the right side plate 16 by an explosion-proof tensioning device, forming a double constraint at the bottom and around the circumference, which fully ensures the safety of tank transportation.

[0065] It should be noted that the connection positions of the angled fixing rings 203 on the tank frame 202 and the U-shaped fixing rings 221 on the bottom plate 11, left side plate 15, and right side plate 16 should be adjusted according to the specifications of the propellant tank 200. For example, when transporting a large-sized vertical propellant tank 200, the angled fixing rings 203 below the middle crossbeam of the tank frame 202 can be tightened and fixed to the U-shaped fixing rings 221 on the left side plate 15 and right side plate 16. When the propellant tank 200 to be transported is of a small size, the angled fixing rings 203 below the upper crossbeam of the tank frame 202 can be tightened and fixed to the U-shaped fixing rings 221 on the left side plate 15 and right side plate 16. The angled fixing ring 203 above the middle crossbeam of the tank frame 202 is generally tightened and fixed with the U-shaped fixing ring 221 on the bottom plate 11. The angled fixing ring 203 above the lower crossbeam of the tank frame 202 is not used under normal transportation conditions because of its low position. However, in special cases such as roads with many slopes, the angled fixing ring 203 above the lower crossbeam of the tank frame 202 can also be tightened and fixed with the U-shaped fixing ring 221 on the bottom plate 11 to further improve the constraint stability.

[0066] In addition, during transportation, the propellant concentration inside the transport device 100 can be monitored using a portable propellant gas concentration monitor. In the event of an accident causing propellant leakage, an emergency response can be carried out using a portable decontamination device 31. Simply open the decontamination device bracket, take out the portable decontamination device, aim the decontamination device nozzle 311 at the leaking propellant, and slowly open the decontamination device outlet valve to complete the emergency response.
