Description

TECHNICAL FIELD

[0001] The present application relates to the field of power supply devices, in particular to a tracked mobile power supply vehicle. BACKGROUND

[0002] As an important emergency power supply equipment, the mobile power supply vehicle can quickly provide emergency power supply in emergency situations such as disasters and power outages, and can also be used as a temporary power supply in power distribution line construction, maintenance and other scenes. Generally, the mobile power supply vehicle adopts a vehicle body structure with a container cargo box, which is used to accommodate various equipment such as prime movers, generators, control devices and cables, so that the mobile power supply vehicle has good integration and mobility, and can be quickly deployed to the place where power is needed.

[0003] At present, the common mobile power supply vehicle on the market usually adopts a wheeled truck chassis, and the core components such as prime movers, generators and control devices are reasonably arranged on the chassis to form a complete mobile power generation system. This design meets the emergency power supply needs in normal situations to a certain extent, and with the flexibility of the wheeled structure, it can quickly reach the general accident scene or the place where temporary power supply is needed, and provide power support for various electrical equipment.

[0004] However, when facing serious natural disasters such as earthquakes, typhoons and floods, the road conditions in the disaster area will be severely damaged. In such bad road conditions, the above-mentioned mobile power supply vehicle relying on the wheeled structure has limitations. Because the wheels cannot normally travel on the severely damaged road, they may even get stuck in the mud or be stuck by obstacles, which makes the mobile power supply vehicle unable to enter the interior of the disaster area. This makes the rescue equipment, communication facilities and medical equipment in the disaster area that urgently need power supply unable to obtain power support in time, seriously affecting the efficiency of rescue work and the life safety guarantee of the disaster-stricken people, greatly limiting the practicality and effectiveness of the mobile power supply vehicle in dealing with serious natural disasters. Although there are methods to improve the driving stability of the power supply vehicle in the prior art, the power supply vehicle is prone to rollover when parked, and the parking stability is poor. SUMMARY

[0005] The present application aims to solve one of the problems in the related art to some extent. To this end, the present application provides a tracked mobile power supply vehicle which has good stability when parked.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions: The application discloses a crawler-type mobile power supply vehicle, which comprises a vehicle body for carrying a power supply device, the vehicle body comprising a vehicle cabin, a vehicle head, a chassis and a crawler assembly arranged below the chassis, the vehicle head being provided with a cab, the chassis being fixedly connected with the vehicle cabin, the power supply device being installed in the vehicle cabin, and the crawler assembly comprising front wheels, rear wheels and an annular crawler belt sleeved on the outer peripheries of the front wheels and the rear wheels; the vehicle body is further provided with a vehicle damping device, the vehicle damping device being installed on the chassis, the vehicle damping device comprising a buffer mechanism, a first connecting mechanism, a second connecting mechanism and a damping mechanism, the first connecting mechanism being used for fastening and connecting the buffer mechanism with the bottom of the vehicle, and the second connecting mechanism being used for fastening and connecting the buffer mechanism with the ground; the buffer mechanism comprises a first buffer part, a second buffer part and at least two curved connecting rod mechanisms, the curved connecting rod mechanisms being hingedly connected with the first buffer part and the second buffer part respectively, and the curved connecting rod mechanisms being connected through a first cross beam; and a spring is further arranged between the first buffer part and the second buffer part.

[0007] In the application, the contact area of the annular crawler with the ground is larger than the contact area of the wheels with the ground in the prior art. Therefore, the pressure per unit contact area can be reduced. Therefore, the power supply vehicle in the application can run on soft surfaces such as mud and snow. Because the surface pressure is low, it is not easy to slip, and it can safely pass through even if the ground is uneven. In addition, because the front wheels and the rear wheels that bear the load are covered by the annular crawler, even if there is a hole in the ground that can accommodate a tire, it can easily pass through without worrying about sinking into the ground. The mobile power supply vehicle in the application can run even in harsh road conditions, so it can reach the destination as soon as possible to supply power when a disaster occurs. The annular crawler traversing the front and back of the vehicle is used for movement, so the contact area with the running surface is large, and even in an environment with severe power demand such as an earthquake, a storm, a flood, etc., excellent running performance can be achieved; when the ground shakes due to an earthquake, etc., the shock absorber can buffer the vertical vibration, and the curved connecting rod mechanism of the buffer mechanism can buffer the left-right direction shaking, and the shock absorber and the curved connecting rod mechanism cooperate to prevent the vehicle from shaking, thereby avoiding the vehicle rollover caused by the earthquake.

[0008] Optionally, the power supply device comprises a diesel generating set, a battery, a prime mover, a radiator, a silencer, a cable winding assembly and a control box which are respectively installed in the vehicle cabin.

[0009] Optionally, the cable winding assembly comprises a cable reel, a reel seat and a reel motor, the reel seat is fixedly connected on the top of the chassis, and the output shaft of the reel motor is fixedly connected with the cable reel.

[0010] Optionally, the application further comprises a fixing device installed on the vehicle body, the fixing device comprising: A plurality of first securing components, including securing straps for securing the vehicle body, the securing straps passing over and abutting the top of the vehicle body, and the two ends of the securing straps being detachably secured to the ground on opposite sides of the vehicle body; And several second fixing components fixed to the bottom surface of the chassis, including a telescopic cylinder, the telescopic cylinder including a piston rod for pressing against the ground, the end of the telescopic cylinder away from the ground being fixed to the vehicle body.

[0011] In this application, the fixing strap wraps around and abuts against the top of the vehicle body, with both ends connected to the ground. Tightening the fixing strap generates horizontal and vertical restraint forces on the vehicle body, preventing it from moving or overturning when subjected to external forces (such as wind or collisions). The retractable piston rod in the telescopic cylinder is used to press against the ground, and its upward reaction force increases the friction between the vehicle body and the ground, further enhancing the vehicle's stability. When the tracked mobile power vehicle is needed, quickly releasing the connection between the fixing strap and the ground and retracting the piston rod of the telescopic cylinder allows the fixing device to be quickly released from the ground, facilitating vehicle movement and improving the mobility and emergency response speed of the mobile power vehicle. Furthermore, the first and second fixing components work together to fix the vehicle body from multiple directions, resisting various external forces and ensuring the vehicle body remains stable in various environments, guaranteeing the safe operation of the tracked mobile power vehicle.

[0012] Optionally, the first fixing component includes two sets of connecting components respectively fixed to both ends of the fixing strap. The connecting component includes a hook portion, a fixing plate, and a connecting portion. The fixing plate is fixed to the ground. One end of the connecting portion is hinged to the fixing plate, and the other end is hinged to the hook portion. The end of the fixing strap is fixed to the hook portion.

[0013] The hinged structure of the connecting part simplifies the installation and disassembly process, eliminating the need for complex alignment and adjustment, thus saving time and manpower. Furthermore, the hinged structure can adapt to fixing requirements at different angles and directions. By adjusting the angle of the hook, the fixing strap can be easily tied to the vehicle body in any posture, enhancing the adaptability of the hook. The fixing strap is connected to the ground through two sets of connecting components, which can evenly transmit the external forces on the vehicle body to the ground, ensuring the stability of the vehicle body under various working conditions and preventing the vehicle body from swaying or moving.

[0014] Optionally, each end of the fixing strap has a hanging ring that is attached to the hook portion, and the hanging ring is attached to the hook portion via a connecting rod.

[0015] The lifting rings at both ends of the fixing strap make installation as simple as hooking the connecting rod into the hook, and disassembly is as simple as removing the lifting ring from the hook. The operation is simple and quick, greatly improving work efficiency.

[0016] Optionally, the hook portion has an opening that allows the connecting rod to enter and exit, and a rotatable lever that opens or closes the opening by rotation.

[0017] The lever makes the installation and removal of the fixing strap simpler and faster. During installation, simply rotate the lever to open the opening, hook the connecting rod into the hook, and then rotate the lever to close the opening. During removal, simply rotate the lever in the opposite direction to open the opening and remove the lifting ring, saving time and manpower.

[0019] The securing strap is flexible, allowing it to conform to the carriage and be easily stored, avoiding the rigid jamming problems of traditional steel cables. It remains stored even during the movement of the power vehicle, without affecting its movement. The flexible construction allows the strap to closely conform to the curved or irregular surfaces of the carriage, adapting to different carriage shapes and increasing its applicability. The flexible material allows the strap to be easily rolled or folded when not in use, facilitating storage on the carriage and preventing it from scattering or tangling with other equipment during movement.

[0020] By evenly arranging fixing components in various parts, the vehicle body can be fixed from multiple points, ensuring sufficient support in all directions to resist lateral winds and maintain stability during emergency power supply, thus guaranteeing the continuity of power supply.

[0021] Optionally, the top of the carriage is curved, and the fixing strap fits the top of the carriage.

[0022] The curved roof of the carriage can disperse wind force, reduce the eddies formed on the carriage surface, and reduce the lateral thrust of wind on the vehicle body. After the flexible fixing straps are attached to the curved roof, the overall stress on the vehicle body is more even, improving the stability of the vehicle body in strong winds.

[0023] Optionally, the second fixing component is provided at the bottom of the front of the vehicle and at the bottom of the chassis.

[0024] By simultaneously installing a second fixing component at the front and bottom of the chassis, the vehicle body can be secured from two important parts at the front and rear, increasing the connection points between the vehicle body and the ground, resisting the lateral force and lift generated by strong winds, significantly improving the stability of the mobile power vehicle under adverse weather conditions, and reducing the risk of rollover.

[0025] Optionally, the telescopic cylinder includes a cylinder barrel, one end of the piston rod extends into the cylinder barrel, and the other end abuts against the ground; the cylinder barrel is fixedly connected to the underside of the chassis.

[0026] The telescopic hydraulic cylinder can contact the ground to fix the vehicle body, effectively resisting the effects of external forces such as wind on the vehicle body, greatly improving the stability of the mobile power vehicle under adverse weather conditions, reducing the risk of vehicle movement or rollover, and ensuring the smooth operation of emergency power supply work. Optionally, the bending linkage mechanism includes a first buffer rod, a second buffer rod, a first rotating shaft, a second rotating shaft, and a third rotating shaft. The first buffer rod and the second buffer rod are hinged together by the first rotating shaft. The first buffer rod and the first buffer part are connected by the second rotating shaft. The second buffer rod and the second buffer part are connected by the third rotating shaft. The first rotating shafts of adjacent bending linkage mechanisms are connected by a first crossbeam. The first buffer part, the second buffer part, and the first crossbeam are arranged parallel to the first crossbeam. Optionally, the first buffer part, the first crossbeam, and the first buffer rods on both sides form a first parallelogram. The first crossbeam, the second buffer part, and the second buffer rods on both sides form a second parallelogram. The first buffer rod and the second buffer rod have the same length, and the first parallelogram and the second parallelogram are symmetrical with shared sides.

Detailed Implementation

[0030] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain the present invention and should not be construed as limiting the present invention.

[0031] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this patent. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0032] Example: like Figures 1 to 3As shown, this embodiment provides a tracked mobile power supply vehicle, including a vehicle body 1 for carrying a power supply device 5. The vehicle body 1 includes a cargo box 11, a cab 13, a chassis 12, and a track assembly 4 disposed below the chassis 12. The cab 13 is provided with a driver's cab, and the chassis 12 is fixedly connected to the cargo box 11. The power supply device 5 is installed inside the cargo box 11. The track assembly 4 includes a front wheel 41, a rear wheel 42, and an annular track 43 sleeved around the front wheel 41 and the rear wheel 42. Figures 6 to 8 As shown, the mobile power supply vehicle 1 is also equipped with a vehicle shock absorption device 70, which is installed on the chassis. The vehicle shock absorption device 70 includes a buffer mechanism 71, a first connecting mechanism 73, a second connecting mechanism 74, and a shock absorber 100. The first connecting mechanism 73 securely connects the buffer mechanism 71 to the bottom of the vehicle, and the second connecting mechanism 74 securely connects the buffer mechanism 71 to an anchor 90 on the ground. The buffer mechanism 71 includes a first buffer part 711, a second buffer part 712, and at least two bending linkage mechanisms 72. The bending linkage mechanisms 72 are respectively hinged to the first buffer part 711 and the second buffer part 712, and the bending linkage mechanisms 72 are connected to each other through a first crossbeam 75. A shock absorber 100 is also provided between the first buffer part 711 and the second buffer part 712.

[0033] In this application, the contact area between the annular track 43 and the ground is larger than that between the wheels and the ground in the prior art. Therefore, the pressure per unit contact area can be reduced. Consequently, the power supply vehicle of this application can travel on soft surfaces such as mud and snow. Due to the low surface pressure, slippage is less likely, allowing safe passage even on uneven ground. Furthermore, since the load-bearing front wheels 41 and rear wheels 42 are covered by the annular track 43, even if there are holes large enough to accommodate the tires, it can easily pass through without worrying about sinking into the ground. The mobile power supply vehicle of this application can travel even in harsh road conditions, thus enabling it to reach its destination and provide power as quickly as possible during disasters. The use of annular tracks 43 running the length of the vehicle results in a large contact area with the driving surface, allowing for excellent operational performance even in environments with severe power demands, such as earthquakes, storms, and floods. In practice, rollovers are less likely to occur in the length direction of the vehicle. They are more likely to occur in the width direction because the width is relatively smaller than the length, making it easier for the center of gravity to shift and cause the vehicle to roll over. Therefore, in actual use, the vehicle shock absorber 70 is installed in the width direction. To make it more stable, the vehicle shock absorber 70 can also be installed in the length direction.

[0034] When ground vibrations such as earthquakes occur, the shock absorber 100 can buffer vertical vibrations, and the bending linkage mechanism 72 can buffer lateral swaying. The shock absorber 100 and the bending linkage mechanism 72 work together to prevent vehicle vibrations, thereby avoiding vehicle rollover caused by earthquakes.

[0035] The power supply unit 5 includes a diesel generator set 57, a battery 51, a prime mover 52, a radiator 53, a muffler 54, a cable winding assembly 55, and a control box 56, all installed in the carriage 11.

[0036] In this embodiment, the diesel generator set 57 integrated within the carriage 11 and the battery 51 constitute a highly efficient and complementary power supply system. Under normal operating conditions, the diesel generator set 57 serves as the primary power source, providing stable power to various high-load equipment thanks to its powerful generating capacity. The components of the power supply unit 5 are arranged along the width of the carriage 11 on both sides to ensure that the weight on both sides is approximately equal, and the space within the carriage is effectively utilized to eliminate blind spots that may easily occur within the carriage 11. This reduces the risk of rollover and improves operational stability. Dividing the left and right sides based on the direction from the rear to the front 13, the battery 51, diesel generator set 57, prime mover 52, radiator 53, and muffler 54 are sequentially arranged on the right side of the carriage 11, while the cable winding assembly 55 and control box 56 are located on the left side. The radiator 53 is located on the right side, close to the prime mover 52 and other heat-generating components, facilitating timely dissipation of heat generated by these components. A well-designed layout ensures the effectiveness of the cooling system, preventing components from overheating and extending their lifespan. Simultaneously, this arrangement promotes airflow within the vehicle, creating a better working environment for other components. Components with related functions are grouped together on one side; for example, power generation and regulation components are concentrated on the right, while electrical control and transmission components are concentrated on the left. This categorized and centralized arrangement makes it easier for maintenance personnel to locate relevant components during inspections, reducing the time spent searching for and troubleshooting faults.

[0037] The cable winding assembly 55 includes a cable reel 551, a reel base 552, and a reel motor 553. The reel base 552 is fixedly connected to the top of the chassis 12, and the output shaft of the reel motor 553 is fixedly connected to the cable reel 551.

[0038] In this embodiment, the power cable is wound and coiled on the cable reel 551. When needed, the cable can be pulled out from the cable reel 551. The output shaft of the reel motor 553 is fixedly connected to the cable reel 551 and rotates under the drive of the motor output shaft.

[0039] This embodiment also includes a fixing device 2 installed on the vehicle body 1. The vehicle body 1 includes a chassis 12 and wheels disposed below the chassis 12. The fixing device 2 includes: a plurality of first fixing components 21, which include fixing straps 211 for securing the vehicle body 1. The fixing straps 211 pass around and abut against the top of the vehicle body 1, and the two ends of the fixing straps 211 are detachably fixed to the ground on opposite sides of the vehicle body 1; and a plurality of second fixing components 22 fixed to the bottom surface of the chassis 12, which include telescopic cylinders 221. The telescopic cylinders 221 include piston rods 2211 for abutting against the ground, and the end of the telescopic cylinders 221 away from the ground is fixed to the vehicle body 1.

[0040] In this embodiment, the vehicle body 1 is secured through the coordinated action of the first fixing component 21 and the second fixing component 22. The fixing strap 211 wraps around and abuts against the top of the vehicle body 1, with both ends connected to the ground on opposite sides of the vehicle body 1, forming constraints on the vehicle body 1 in both horizontal and vertical directions, preventing the vehicle body 1 from moving or overturning when subjected to external forces (such as wind or collisions). The piston rod 2211 of the telescopic cylinder 221 abuts against the ground, and its fixed end to the vehicle body 1 applies a downward force, increasing the friction between the vehicle body 1 and the ground, further enhancing the stability of the vehicle body 1, and also resisting vertical swaying of the vehicle body 1 to a certain extent. When the tracked mobile power vehicle is needed, by quickly releasing the connection between the fixing strap 211 and the ground and retracting the piston rod 2211 of the telescopic cylinder 221, the fixing device 2 can be quickly released from its constraint on the ground, facilitating the movement of the vehicle body 1 and improving the mobility and emergency response speed of the mobile power vehicle. Figure 4 and Figure 5 As shown, the first fixing component 21 includes two sets of connecting components 212 respectively fixed to both ends of the fixing strap 211. The connecting component 212 includes a hook portion 2121, a fixing plate 2122 and a connecting portion 2123. The fixing plate 2122 is fixed to the ground. One end of the connecting portion 2123 is hinged to the fixing plate 2122 and the other end is hinged to the hook portion 2121. The end of the fixing strap 211 is fixed to the hook portion 2121.

[0041] In this embodiment, two sets of first connecting components 212 connect both ends of the fixing strap 211 to the ground. The connection between the hook portion 2121 and the fixing strap 211 achieves the binding and constraint of the fixing strap 211 on the vehicle body 1. The two ends of the connecting portion 2123 are hinged to the fixing plate 2122 and the hook portion 2121 respectively, allowing the hook portion 2121 to rotate flexibly within a certain range, facilitating the installation and removal of the fixing strap 211. When the vehicle body 1 is subjected to external force, the fixing strap 211 transmits the force to the ground through the connecting components 212, using the ground's reaction force to balance the external force on the vehicle body 1, thereby maintaining the stability of the vehicle body 1 and preventing it from moving or overturning. Specifically, the hook portion 2121 is made of metal and is designed as a circle with a central hole, facilitating the insertion and fixing of the end of the fixing strap 211. The fixing plate 2122 is a steel plate, which can be fixed to the ground by bolts or other fasteners, providing an installation base for the connecting components 212. The connecting part 2123 is a metal part. One end is connected to the fixing plate 2122 by a hinge such as a pin, and the other end is also hinged to the hook part 2121 by a pin, allowing the hook part 2121 to rotate freely within a certain angle range for convenient operation. In other embodiments, an electromagnet that cooperates with the fixing plate 2122 can be buried in the ground. When the electromagnet is energized, it can attract the fixing plate 2122, and when the power is turned off, the fixing plate 2122 can be separated from the electromagnet, realizing the movement of the mobile power supply vehicle.

[0042] The fixing strap 211 has a hanging ring 2111 at each end, and the hanging ring 2111 is hung on the hook part 2121 through the connecting rod.

[0043] In this embodiment, each end of the fixing strap 211 has a hanging ring 2111, which is integrally formed with the fixing strap 211. In other embodiments, the hanging rings 2111 can also be firmly connected to the main body of the fixing strap 211 by weaving, sewing, or other methods. The connecting rod has a fixing ring at each end. The hanging rings 2111 at both ends of the fixing strap 211 allow for simple installation by hooking the fixing rings of the connecting rod into the hook portion 2121, and simple disassembly by removing the hanging rings 2111 from the hook portion 2121, making the operation simple and quick and improving work efficiency. Additionally, this embodiment also includes a connecting rod, which is located below the hanging rings 2111, meaning the hanging rings 2111 are fixed to the hook portion 2121 via the connecting rod.

[0044] The hook portion 2121 has an opening 2121a that allows the connecting rod to enter and exit, and a rotatable lever 2121b, which opens or closes the opening 2121a by rotation.

[0045] In this embodiment, the lifting rings 2111 at both ends of the fixing strap 211 are connected to connecting rods. The connecting rods have fixing rings at both ends, which enter through the openings 2121a of the hook portions 2121. The hook portions 2121 attach the lifting rings 2111 to secure the vehicle body 1, transmitting the external force on the vehicle body 1 to the connecting assembly 212 via the fixing strap 211 and hook portions 2121, and then to the ground. The ground reaction force maintains the stability of the vehicle body 1. The lever 2121b allows the openings 2121a of the hook portions 2121 to open or close flexibly. When installing the fixing strap 211, rotating the lever 2121b opens the opening 2121a, facilitating the entry of the lifting rings 2111. After installation, the lever 2121b closes the opening 2121a to prevent the connecting rods from accidentally coming off. Specifically, the lever 2121b is connected to a torsion spring to maintain a tendency to close the opening 2121a.

[0046] The vehicle body 1 includes a carriage 11 and a cab 13. The cab 13 is equipped with a driver's cab. The chassis 12 is fixedly connected to the carriage 11. The power supply unit 5 is installed inside the carriage 11.

[0047] In this embodiment, the carriage 11 serves as the installation space for the power supply unit 5, providing protection against damage from the external environment. The carriage 11 is typically made of robust and durable materials, such as steel, possessing excellent wind and pressure resistance. The chassis 12 is located below the carriage 11 and is fixedly connected to it, providing support and load-bearing capacity for the entire vehicle body 1. Wheels are located under the chassis 12 for easy vehicle movement. The chassis 12 usually employs a high-strength frame structure to ensure stability during driving and parking. The front 13 houses the driver's cab for operation. Additionally, the cab can be equipped with various control devices and instruments, allowing the driver to monitor vehicle status and driving information in real time. Once the mobile energy storage vehicle reaches its designated location, the vehicle body 1 is secured using the fixing device 2 to prevent movement or shaking during operation. The combination of the vehicle body 1 structure and the fixing device 2 allows the tracked mobile power supply vehicle to move flexibly to different locations and quickly and stably settle upon arrival, meeting energy storage needs in various scenarios. For example, in scenarios such as emergency rescue and temporary power supply, energy storage equipment can be quickly deployed to the site.

[0048] The fixing belt 211 is flexible in structure, and the surface of the carriage 11 is provided with a winding assembly 3 for winding the fixing belt; the winding assembly 3 includes a winding roller 31 and a handle 32. The fixing belt 211 is wound around the winding roller 31, and one end of the handle 32 has a rotating shaft that extends into the winding roller 31. The winding roller 31 rotates with the rotating shaft, and a torsion spring is sleeved on the rotating shaft to keep the rotating shaft rotating in the direction of rotation.

[0049] In this embodiment, the winding assembly 3 consists of a winding roller 31 and a handle 32. The winding roller 31 is fixed to the frame of the carriage 11 by a bracket, and its surface may also be provided with a spiral guide groove to achieve regular winding of the fixing tape. The winding roller 31 rotates itself to store the fixing tape. A torsion spring allows the winding roller 31 and the rotating shaft to stop at their current position after the external force is removed. The stopping mechanism of the torsion spring is existing technology and has many implementation methods, which will not be elaborated here.

[0050] like Figure 2 As shown, the carriage 11 has a front, middle and rear section along its length, and each of the front, middle and rear sections is equipped with three sets of first fixing components 21.

[0051] In this embodiment, to enhance the stability of the mobile power supply vehicle and prevent it from tipping over in severe weather conditions such as strong winds, fixing components are installed at different locations on the vehicle body 11. The vehicle body 11 is divided into a front, middle, and rear section along its length, and each section is equipped with three sets of first fixing components 21. Since the overall length of the vehicle body 11 is relatively long, the stress on different parts may vary under wind conditions. By evenly arranging fixing components in each section, the vehicle body 1 can be fixed from multiple points, ensuring sufficient support in all directions to resist lateral wind forces. This guarantees the stability of the mobile power supply vehicle during emergency power supply and ensures the continuity of power supply.

[0052] The top of the carriage 11 is arc-shaped, and a limiting groove is provided on the top of the carriage 11. The fixing strap 211 is attached to the bottom wall of the limiting groove.

[0053] In this embodiment, the top of the carriage 11 is arc-shaped. The arc-shaped top can change the direction and manner in which wind force acts on the surface of the carriage 11, reducing the direct impact and lift effect of wind force on the carriage 11, and reducing the risk of rollover. The flexible fixing strap 211 can fit tightly against the top of the arc-shaped carriage 11. Through the connection with the fixing points on the top and bottom of the carriage 11, the wind force is evenly distributed to various parts of the vehicle body 1. The vehicle body 1 itself and the ground support force are used to resist the wind force, thereby ensuring the stable operation of the mobile power vehicle in emergency power supply scenarios.

[0054] A second fixing component 22 is provided at the bottom of both the front end 13 and the bottom of the chassis 12.

[0055] A second fixing component 22 is installed at the bottom of the front 13 and the bottom of the chassis 12. The front 13 and the chassis 12 serve as important support parts of the vehicle body 1. The second fixing component 22 connects to the ground, transmitting the force generated by the wind to the ground. The friction and support of the ground are used to resist the wind force, thereby enhancing the overall stability of the mobile power vehicle and enabling it to stably provide power for emergency scenarios under severe weather conditions.

[0056] The telescopic cylinder 221 includes a cylinder barrel 2212, one end of the piston rod 2211 extends into the cylinder barrel 2212, and the other end abuts against the ground; the cylinder barrel 2212 is fixedly connected to the bottom of the chassis 12.

[0057] In this embodiment, the telescopic cylinder 221 includes a cylinder barrel 2212, which is fixed to the vehicle body 1. Additionally, the telescopic cylinder 221 may also include seals and a hydraulic system. The piston rod 2211 can extend and retract under the action of the hydraulic system. The seals ensure that the hydraulic oil inside the cylinder does not leak, ensuring the normal operation of the telescopic function. Furthermore, anti-slip pads made of rubber or other anti-slip materials can be installed at the end of the piston rod 2211 to increase the friction between the piston rod 2211 and the ground, preventing the cylinder from sliding on the ground. The cylinder barrel 2212 is made of high-strength, corrosion-resistant metal materials, such as alloy steel, to ensure its reliability and durability under high pressure and complex environments. One end of the cylinder barrel 2212 is closed, and the other end is open 2121a for the piston rod 2211 to move in and out. The piston rod 2211 is also made of high-strength materials, and its surface undergoes special treatment, such as chrome plating, to improve wear resistance and corrosion resistance. The movement of piston rod 2211 within cylinder 2212 is controlled by a hydraulic system, and extension and retraction are achieved by hydraulic oil.

[0058] The power supply unit 5 includes a diesel generator set and a power output box. The power output box is equipped with a coupler socket, which is connected to the diesel generator set.

[0059] In this embodiment, the mobile power vehicle needs to provide power quickly and stably to various electrical devices. The diesel generator set, as the core power generation component, converts chemical energy into mechanical energy by burning diesel fuel, which then drives the generator to produce electrical energy. The power output box plays a crucial role in power distribution and output, and its coupler socket is used to connect the cables of external electrical devices. The coupler socket connects to the diesel generator set, enabling the electrical energy generated by the generator set to be transmitted to external devices, meeting emergency power supply needs. Preferably, the first buffer 711 is a crossbar spanning the left and right first connecting mechanisms 73, and the second buffer 712 can be a crossbar spanning the left and right second connecting mechanisms 74. The first buffer 711 can also be a fixed block connected vertically to the first connecting mechanism 73 and the bending linkage mechanism 72, respectively, and the second buffer 712 can also be a fixed block connected vertically to the second connecting mechanism 74 and the bending linkage mechanism 72, respectively. Using fixed blocks can avoid interference with the vehicle. In one embodiment, as... Figure 6As shown, the bending linkage mechanism 72 includes a first buffer rod 721, a second buffer rod 722, a first rotating shaft 723, a second rotating shaft 724, and a third rotating shaft 725. The first buffer rod 721 and the second buffer rod 722 are hinged together by the first rotating shaft 723. The first buffer rod 721 is connected to the first buffer part 711 by the second rotating shaft 724. The second buffer rod 722 is connected to the second buffer part 712 by the third rotating shaft 725. The first rotating shafts 723 of adjacent bending linkage mechanisms 72 are connected by a first crossbeam 75. The first buffer part 711, the second buffer part 712, and the first crossbeam 75 are arranged parallel to each other.

[0060] In specific implementation, the first rotating shaft 723, the second rotating shaft 724, and the third rotating shaft 725 rotate in the same direction, parallel to the extension direction of the first crossbeam 75. When the vehicle rolls over, it tends to tilt to one side while the other side rises. When using the vehicle shock absorber 70 of this application, when the vehicle has a tendency to roll over and presses down on one side, the first buffer rod 721 and the second buffer rod 722 near the bending linkage mechanism 72 on the overturned side will tend to move closer to each other, while the first buffer rod 721 and the second buffer rod 722 on the side where the vehicle is raised will tend to move away from each other. When the vehicle tilts to the left, the angle between the first buffer rod 721 and the second buffer rod 722 of the left bending linkage mechanism 72 decreases, and the first crossbeam 75 tends to push to the right. At the same time, the right side of the vehicle rises, and the angle between the first buffer rod 721 and the second buffer rod 722 of the right bending linkage mechanism 72 increases, pushing the first crossbeam 75 to the left. The first crossbeam 75 has sufficient rigidity and stress to withstand the force of the bending linkage mechanisms 72 on both sides and keep the bending linkage mechanisms 72 on both sides stationary, thereby ensuring that the vehicle does not sway in the left and right directions. When the vehicle tilts to the right, the angle between the first buffer rod 721 and the second buffer rod 722 of the right-side bending linkage mechanism 72 tends to decrease, and the first crossbeam 75, acted upon by the right-side bending linkage mechanism 72, tends to move to the right. Simultaneously, the angle between the first buffer rod 721 and the second buffer rod 722 of the left-side bending linkage mechanism 72 increases, and the left-side bending linkage mechanism 72 tends to pull the first crossbeam 75 to the left. The first crossbeam 75 has sufficient stress and strength to counteract the forces exerted by the bending linkage mechanisms 72 on both sides. In one embodiment, as... Figure 6As shown, the first buffer section 711, the first crossbeam 75, and the first buffer rods 721 on both sides form a first parallelogram 771. The first crossbeam 75, the second buffer section 712, and the second buffer rods 722 on both sides form a second parallelogram 772. The first buffer rods 721 and the second buffer rods 722 have the same length, and the first parallelogram 771 and the second parallelogram 772 are symmetrical and share a common side. Specifically, by setting the first buffer section 711, the first buffer rods 721 arranged parallel on both sides, and the crossbeam, a first parallelogram is formed. By setting the second buffer section 712, the second buffer rods 722 arranged parallel on both sides, and the top crossbeam, a second parallelogram is formed. The two parallelograms share the first crossbeam 75 as one side and share the first rotation axis 723, so that the upper and lower parallelograms share a common side. When the vehicle body tilts to one side, the position of the second buffer part 712 in the second parallelogram 772 at the bottom remains fixed. Because the first buffer rod 721 and the second buffer rod 722 have the same length, and the first buffer part 711, the first crossbeam 75, and the second buffer part 712 are arranged parallel to each other, the hinge points of the first buffer part 711 and the first buffer rod 721, and the hinge points of the second buffer part 712 and the second buffer rod 722 coincide in their horizontal projections. When a force is applied from one side, because the first parallelogram 771 and the second parallelogram 772 share a common edge and are symmetrical, and given that the first buffer rod 721 and the second buffer rod 722 have the same length, the position of the second buffer part 712 in the second buffer part 712 remains fixed. The hinge points of the first and second buffer rods 721 and 722 will always remain aligned in the horizontal projection. At this time, the bending linkage mechanism 72 will be subjected to heavy pressure, causing a change in its vertical height, but its lateral position will not change. Furthermore, the shock absorber 100 provides cushioning in the vertical direction. Therefore, when the first and second buffer rods 721 and 722 of the bending linkage mechanism 72 are of the same length and are divided vertically by the first crossbeam 75 into two symmetrical parallelograms with shared sides, they can effectively buffer lateral swaying. Combined with the shock absorber 100, this can significantly reduce vehicle swaying caused by earthquakes or other vibrations, preventing rollover. It also provides good support when the vehicle is parked in a position with a height difference, creating a risk of rollover, preventing vehicle tilting. Further, as... Figure 7As shown, the bending linkage mechanism 72 is provided with a sliding limiting structure 80, which includes a first limiting rod 81, a second limiting rod 82, and a fourth rotating shaft 83. The first limiting rod 81 and the second limiting rod 82 are hinged together by the fourth rotating shaft 83. The other end of the first limiting rod 81 is hinged to the first buffer rod 721, and the other end of the second limiting rod 82 is hinged to the second buffer rod 722. The first crossbeam 75 passes through the first rotating shaft 723 and the fourth rotating shaft 83. The first crossbeam 75 is connected to the first rotating shaft 723 and the fourth rotating shaft 83. Shaft 83 is slidably connected; the first limiting rod 81 is the first side 84, the second limiting rod 82 is the second side 85, the distance from the hinge point of the first limiting rod 81 and the first buffer rod 721 to the end of the first buffer rod 721 facing the first rotating shaft 723 is the third side 86, and the distance from the hinge point of the second limiting rod 82 and the second buffer rod 722 to the end of the first buffer rod 721 facing the first rotating shaft 723 is the fourth side 87. The lengths of the first side 84, the second side 85, the third side 86, and the fourth side 87 are equal, forming a rhombus 88. In specific implementation, the first side 84, the second side 85, the third side 86, and the fourth side 87 are of the same length and are connected to form a rhombus 88 with four equal sides. At this time, the first crossbeam 75 passes through the first rotating shaft 723 and the fourth rotating shaft 83 and is connected to the diagonal of this rhombus 88. The angle between the first side 84 and the first crossbeam 75 inside the rhombus 88 is 1 angle, the angle between the second side 85 and the first crossbeam 75 inside the rhombus 88 is 2 angle, the angle between the third side 86 and the first crossbeam 75 inside the rhombus 88 is 3 angle, the angle between the fourth side 87 and the first crossbeam 75 inside the rhombus 88 is 4 angle, the angle between the first buffer rod 721 and the first buffer part 711 is 5 angle, and the angle between the second buffer rod 722 and the second buffer part 712 is 6 angle. The angles of 1, 2, 3, and 4 are the same. The 5 and 3 angles are alternate interior angles, and the 6 and 4 angles are alternate interior angles. Therefore, the angles of 1, 2, 3, 4, 5, and 6 angles are all the same. When the vehicle tends to roll to the left, the angle between the first buffer bar 721 and the second buffer bar 722 tends to decrease. At this time, angles 3 and 4 tend to decrease, as do angles 1 and 2. The first rotating shaft 723 and the fourth rotating shaft 83 slide relative to the first crossbeam 75 to the right. The first crossbeam 75 has sufficient strength and stress to prevent it from bending and remains horizontal. At this time, angles 5 and 6 also decrease. However, because the angle of the first rotating shaft 723 relative to the first crossbeam 75 decreases due to the rightward sliding, the hinge points of the first buffer part 711 and the first buffer bar 721, and the hinge points of the second buffer part 712 and the second buffer bar 722 remain unchanged in the horizontal direction, but their height in the vertical direction tends to decrease. At this time, the shock absorber 100 can buffer the vertical direction. The tendency for the vehicle to roll to the right is similar and will not be described in detail here.Preferably, a sliding limit structure 80 can be provided on only one of the bending linkage mechanisms 72, or on each bending linkage mechanism 72. The first crossbeam 75 is fixedly connected to the leftmost or rightmost first rotating shaft 723, and slidably connected to the other first rotating shafts 723 and the fourth rotating shaft 83. This ensures that when pressed down, only the relative positions of the first rotating shafts 723 and the fourth rotating shaft 83 with the first crossbeam 75 change, while the positions of the first buffer part 711 and the second buffer part 712 remain unchanged, thus buffering the horizontal swaying of the vehicle. It should be noted that it is not necessary to limit the length of the first buffer rod 721 to be the same as the length of the second buffer rod 722. It is sufficient that the angles of the first side 84, the second side 85, the third side 86, and the fourth side 87 are the same. The length of the first buffer rod 721 can be greater than the length of the second buffer rod 722, or the length of the first buffer rod 721 can be less than the length of the second buffer rod 722. Preferably, for example... Figure 8 As shown, when the first buffer part 711 and the second buffer part 712 are fixed blocks, a second crossbeam 76 can be provided. The second crossbeam 76 is arranged parallel to the first crossbeam 75 and can be connected to the first buffer rod 721 or to the second crossbeam 76, which can avoid interference between the first buffer part 711 and the bottom of the vehicle. Further, as... Figure 7As shown, springs 110 are provided between the first buffer portion 711 and the first crossbeam 75, and between the first crossbeam 75 and the second buffer portion 712. The springs 110 enhance the vertical buffering capacity. Further, a first swing mechanism 78 is provided between the first connecting mechanism 73 and the first buffer portion 711. The first swing mechanism 78 includes a first bracket 781 disposed on the first connecting mechanism 73 and a first swing member 782 fastened to the first buffer portion 711, with the first bracket 781 and the first swing member 782 hinged together. A second swing mechanism 79 is also provided between the second connecting mechanism 74 and the second buffer portion 712. The second swing mechanism 79 includes a second bracket 791 disposed on the second connecting mechanism 74 and a second swing member 792 fastened to the second buffer portion 712, with the second bracket 791 and the second swing member 792 hinged together. Preferably, the buffering direction of the first and second buffers is perpendicular to the buffering direction of the first rotating shaft 723. When the vehicle shock absorber 70 is installed in the vehicle width direction, the first swing mechanism 78 and the second swing mechanism 79 rotate back and forth along the vehicle length direction, which can buffer the front and rear vibrations. Therefore, when the vehicle shock absorber 70 is installed in the vehicle width direction, the shock absorber 100 and the spring 110 buffer the vertical vibrations, the bending linkage mechanism 72 and the first crossbeam 75 buffer the vehicle-direction vibrations, and the first swing mechanism 78 and the second swing mechanism 79 buffer the vehicle-length vibrations, which can buffer vibrations in all directions and is also suitable for potholes or terrain conditions where one side is higher than the other. Further, as Figure 9 As shown, the first connecting mechanism 73 includes a mounting base 731 and a first connecting portion 732. The mounting base 731 is securely connected to the bottom of the vehicle. The first connecting portion 732 has a through first mounting hole 733. A screw 734 is fixed to the side of the mounting base 731 near the first connecting portion 732, passing through the first mounting hole 733. A bolt 735 fixes the first connecting portion 732 to the bottom of the mounting base 731. The bottom of the first connecting portion 732 is connected to the first swing mechanism 78. The first connecting mechanism 73 ensures a stable connection between the vehicle and the vehicle shock absorber 70. Further, as... Figure 10As shown, the second connecting mechanism 74 includes a second connecting portion 741 and a screw 734 mounted on the top of the anchor 90. The second connecting portion 741 has a through second mounting hole 742, through which the screw 734 passes. A bolt 735 is used to fasten the second connecting portion 741 to the top of the anchor 90. The top of the second connecting portion 741 is connected to the second swing mechanism 79. The bending linkage mechanism 72 is fastened to the anchor 90 via the second connecting mechanism 74. Further, the diameter of the second mounting hole 742 is larger than the nominal diameter of the screw 734. Because the vehicle cannot be parked perfectly precisely at the position fixed by the anchor 90, setting the diameter of the second mounting hole 742 to be larger than the nominal diameter of the screw 734 allows for a larger parking space without requiring excessive precision, and also allows the second connecting portion 741 to be fixed to the anchor 90. Preferably, the vehicle shock absorber 70 can also be placed in a depression or on a slope to support the vehicle. When moving cable reel 551 to the side of a vehicle to perform operations such as pulling out or winding power output cables, harsh power demand environments may be encountered, such as working on slopes or in emergency situations. In these special circumstances, cable reel 551 should be positioned at a height easily accessible to the operator. Based on this requirement, Figures 11 to 16A modified cable reel 551 device is shown. This device moves the cable reel 551, along with the reel platform, to the side of the vehicle. Unlike the aforementioned cable reel 551 device, this modified cable reel 551 device has a lifting function, with improvements made only to the structure of the reel platform mover 120 used to move the reel platform to the side of the vehicle. The improved reel platform mover 120 includes the following components: a rotating chassis guide rail 130 extending laterally on a chassis 12 shared with the vehicle; a moving structure 140 consisting of a horizontal moving frame 160 and a lifting moving frame 170, wherein the horizontal moving frame 160 can move in and out of the vehicle side via the reel platform guide rail, and the lifting moving frame 170 can be raised and lowered relative to the horizontal moving frame 160, with the reel platform mounted at the lower end of the lifting moving frame 170. A shelf 150 is provided at the bottom of the horizontal moving frame 160, which meshes with a pinion gear on the equipment placement platform. By activating the motor (not shown) of the horizontal moving frame 160, which drives the pinion gear, the horizontal moving frame 160 can move laterally along the reel table floor guide rail. Although not shown, the motor used for the horizontal moving frame 160 is the same as that used for the reel table floor mover 120, and can be operated via a reel table floor horizontal movement switch (not shown) located in the switch box. The lifting moving frame 170 can move up and down along the inner side of the vertical frame of the horizontal moving frame 160. Specifically, it uses the same principle as the transmission mechanism consisting of a frame and a pinion gear located between the horizontal moving frame 160 and the equipment placement platform (this transmission mechanism is driven by a switch-controlled motor located in the switch box) to achieve the movement of the lifting moving frame 170 relative to the vertical frame of the horizontal moving frame 160. Alternatively, (not shown), a hydraulic cylinder can be installed between the lifting moving frame 170 and the vertical frame. This hydraulic cylinder can be designed such that a hydraulic pump is controlled by an electric motor, thereby enabling the lifting moving frame 170 to be raised and lowered to the vertical frame.

Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
