[0002] A mobile three-phase power emergency support device is a flexible and movable power equipment that can quickly provide stable three-phase AC power to various three-phase electrical equipment to ensure their continuous operation when the mains power is interrupted or the power supply is unstable. It usually integrates a power generation unit, energy storage unit, power conversion and control components, and has a movable cabinet or trailer chassis structure.

[0003] Mobile three-phase power emergency support devices require rapid deployment and heat dissipation throughout their use. However, existing device designs lack automated deployment capabilities, and heat dissipation components (such as fans and vents) are fixed and cannot be flexibly adjusted to meet environmental requirements. When rapid heat dissipation is required, the heat dissipation device cannot be quickly deployed through mechanical linkage, resulting in poor environmental adaptability.

[0004] Mobile three-phase emergency power supply devices inevitably generate heat throughout their use. Traditional mobile three-phase emergency power supply devices lack active heat dissipation mechanisms when operating outdoors in high temperatures (such as at summer construction sites) or in semi-enclosed spaces (such as underground garages and tunnel repairs), relying solely on natural heat dissipation or simple ventilation. This can easily cause the ambient temperature around the device to exceed the rated operating range, triggering overheating protection and shutting down the device, impacting power supply stability.

[0014] In some embodiments, a temperature sensor is provided on the side wall of the three-phase power supply, and the temperature sensor is connected to the PLC control panel; when the detection value of the temperature sensor exceeds a preset threshold, the PLC control panel automatically starts the synchronous motor and the air cooling module.

[0029] To further illustrate the technical means and effects employed by the present invention to achieve its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments. In the following description, different references to "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0030] In the description of the present invention, it should be made clear that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence; the terms "vertical", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "horizontal", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention, and do not mean that the devices or elements referred to must have a specific direction or position, and therefore cannot be understood as limitations on the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0032] like Figure 1-Figure 7 As shown, an embodiment of the utility model provides a mobile three-phase power emergency guarantee device, including a three-phase power supply 1, at least one side wall of the three-phase power supply 1 is provided with a storage slot 2; a synchronous motor 21 and a first screw 22 driven and connected to the synchronous motor 21 are arranged in the storage slot 2; a drive sleeve 24 is sleeved on the first screw 22; the drive sleeve 24 is hinged to one end of a first hinged rod 25, and the other end of the first hinged rod 25 is hinged to a side plate 26; the side plate 26 is located on one side of the axial direction of the first screw 22 and is hinged to the side wall of the three-phase power supply 1; an air cooling module is fixedly installed on the side plate 26; when the synchronous motor 21 drives the first screw 22 to rotate, the drive sleeve 24 moves axially along the first screw 22 and pushes the side plate 26 to expand or retract through the first hinged rod 25.

[0033] In this embodiment, a storage groove 2 is provided on the side wall of the three-phase power supply 1, a synchronous motor 21 and a first screw 22 are built into the storage groove 2, and a drive sleeve 24 is connected to the side panel 26 (the side panel 26 is hinged to the three-phase power supply 1 and is equipped with an air cooling module) through a first hinge rod 25. When the synchronous motor 21 drives the first screw 22 to rotate, the drive sleeve 24 drives the side panel 26 to expand / contract.

[0034] This solution utilizes the mechanical linkage of a synchronous motor 21, a first screw 22, and a first hinged rod 25 to automatically deploy and retract the side panels 26 (including the air-cooling module). When heat dissipation is required, they deploy, increasing the contact area between the air-cooling module and the outside air. When heat dissipation is not required, they retract, reducing space usage and protecting the module. This solution directly addresses the existing issue of fixed heat dissipation components and their inability to quickly respond to heat dissipation needs. By enabling automated adjustment of the heat dissipation structure, the device improves its adaptability to diverse environments (such as high-temperature outdoor environments and semi-enclosed spaces), quickly meeting heat dissipation requirements, and preventing equipment shutdowns caused by overheating due to untimely heat dissipation.

[0035] In some embodiments, the side wall of the three-phase power supply 1 having the storage slot 2 is also provided with a guide groove, and a guide rod 23 parallel to the first screw 22 is arranged in the guide groove; a sliding sleeve is slidably sleeved on the guide rod 23; the sliding sleeve is hinged to one end of the second hinged rod, and the other end of the second hinged rod is hinged to the side panel 26.

[0036] In this embodiment, a guide groove and a guide rod 23 parallel to the first screw rod 22 are additionally provided on the side wall of the three-phase power supply 1 , and a sliding sleeve on the guide rod 23 is hinged to the side plate 26 via a second hinge rod.

[0037] If the side panels 26 are driven only by the first hinge rod 25 , there may be a problem of insufficient stability (eg, shaking of the side panels 26 ) during expansion / contraction.

[0038] This solution incorporates a guide rod 23, a sliding sleeve, and a second hinge rod. The second hinge rod and the first hinge rod 25 form a "double hinge support." The guide rod 23 restricts the sliding sleeve's movement, ensuring that the side panels 26 move smoothly along a predetermined trajectory. This overcomes the potential stability issues associated with a single hinge structure. This improves the structural stability of the side panels 26 during deployment and retraction, preventing shaking that could affect the cooling efficiency of the air-cooling module and extending the device's service life.

[0039] In some embodiments, the hinge point between the first hinge rod 25 and the side panel 26 is located at 2 / 3 of the height of the side panel 26 ; the hinge point between the second hinge rod and the side panel 26 is located at 1 / 2 of the height of the side panel 26 .

[0040] In this embodiment, the hinge point between the first hinge rod 25 and the side panel 26 is located at 2 / 3 of the height of the side panel 26, and the hinge point between the second hinge rod is located at 1 / 2 of the height.

[0041] If the hinge point position of the double hinge structure is not designed properly, it may cause the side panels 26 to be unevenly stressed (eg, tilted when unfolded, stuck when folded).

[0042] This solution balances the forces on the upper and lower parts of the side panels 26 by placing hinge points at 2 / 3 and 1 / 2 of their height, respectively. The upper hinge point (at 2 / 3) primarily bears the thrust during deployment, while the lower hinge point (at 1 / 2) provides additional stability, preventing deformation of the side panels 26 due to concentrated forces. This optimizes the mechanical distribution of the dual-hinge structure, ensuring uniform force distribution on the side panels 26 during deployment and retraction, reducing structural losses, improving movement smoothness, and further ensuring the operational stability of the air-cooled module.

[0043] In some embodiments, a placement groove 3 is opened on the top surface of the three-phase power supply 1; a second motor 38 and a second screw 32 connected to the second motor 38 are arranged in the placement groove 3; two first threaded sleeves 33 with reverse threads are sleeved on the second screw 32; the two first threaded sleeves 33 are hinged to one end of two first rotating rods 34, the middle parts of the two first rotating rods 34 are hinged to each other, and the other ends of the two first rotating rods 34 are jointly hinged to the bottom of the solar panel 37.

[0044] In this embodiment, a placement groove 3 is provided on the top surface of the three-phase power supply 1, and the placement groove 3 has a second motor 38 and a second screw 32 built in. The second screw 32 is provided with two first threaded sleeves 33 with opposite threads. The first threaded sleeve 33 is connected to the solar panel 37 through the first rotating rod 34. When the second motor 38 drives the second screw 32 to rotate, it can drive the solar panel 37 to unfold.

[0045] Traditional emergency support devices rely solely on built-in power supplies, have limited battery life, and have single functions.

[0046] This solution utilizes the linkage of a second motor 38, a second screw 32, two counter-threaded first threaded sleeves 33, and a first rotating rod 34 to automatically deploy and retract the solar panel 37. When used outdoors, it deploys to charge using solar energy; when not in use, it retracts into the storage slot 3, saving space. The addition of solar power expands the device's energy sources, achieving energy self-sufficiency and extending its battery life. This enhances its practicality in scenarios without an external power source (such as field repairs), providing a more comprehensive range of functions.

[0047] In some embodiments, a third screw is provided in the placement groove 3, and two second threaded sleeves with reverse threads are sleeved on the third screw; a transmission wheel 35 is fixed in the middle of the third screw and the second screw 32, and the two transmission wheels 35 are connected by a synchronous belt 36.

[0048] The top of the placement slot 3 is rotatably connected to a cover plate 16 , and a magnetic buckle is provided on the edge of the cover plate 16 for locking with the upper surface of the three-phase power supply 1 .

[0049] In this embodiment, a third screw (with two reverse-threaded second threaded sleeves) is added to the placement groove 3, and the third screw is connected to the second screw 32 through a transmission wheel 35 and a synchronous belt 36; a cover plate 16 with a magnetic buckle is provided on the top of the placement groove 3.

[0050] If the solar panel 37 is driven by only a single set of screws, there may be a problem of uneven force when it is unfolded (such as the panel tilting), and the placement slot 3 has no protective structure, which makes it easy for dust to enter.

[0051] This solution uses a synchronous belt 36 to link the twin screws (the third screw and the second screw 32) so that the forces at both ends of the solar panel 37 are balanced, making the deployment more stable; the cover 16 is locked by a magnetic snap, which can protect the components in the placement slot 3 (such as the screws and the motor) from dust and rain erosion.

[0052] This solves the stability issues of a single screw drive and the protection issues of the placement slot 3. It also improves the stability of the solar panel 37 during deployment and extends the service life of internal components. The cover 16 design enhances the equipment's dust and water resistance, making it suitable for complex outdoor environments.

[0053] Two mounting grooves 31 can be set at the bottom of the placement groove 3. The third screw and the second screw 32 are rotatably set in the two mounting grooves 31 respectively. A through groove is set between the two mounting grooves 31, and the synchronous belt 36 is located in the through groove.

[0054] Two independent mounting grooves 31 are provided at the bottom of the placement groove 3, which are used to accommodate the third screw and the second screw 32 respectively, so that the two screws are separated from each other in physical space to avoid structural interference caused by too close distance during operation (such as vibration collision when the screws rotate).

[0055] The mounting groove 31 provides an independent supporting space for the screw, reducing direct erosion of the external environment (such as dust and water vapor) on the screw threads and transmission components, thereby extending the service life.

[0056] The through groove between the two mounting grooves 31 is specifically used to accommodate the synchronous belt 36, so that the belt transmission path is confined to a closed space, avoiding entanglement or friction with the solar panel 37 or other components in the placement groove 3 (such as the first rotating rod 34), ensuring a stable and reliable transmission process.

[0057] The third screw and the second screw 32 are connected by a timing belt 36 and a drive pulley 35, enabling the two screws to rotate synchronously. Because the third and second screws 32 are respectively equipped with threaded sleeves with opposite threads (the first threaded sleeve 33 and the second threaded sleeve), the synchronous rotation ensures that the travel distance and speed of the sleeves on both sides are exactly the same.

[0058] This synchronization can drive the two sets of first rotating rods 34 connected to the bottom of the solar panel 37 to exert force evenly, avoiding tilting, jamming or structural deformation of the solar panel 37 caused by the difference in the speed of the screw on one side, ensuring a smooth and smooth expansion / contraction process of the panel.

[0059] Compared with single-screw drive, twin-screw synchronous drive can disperse the weight load of the solar panel 37, reduce the force strength of a single screw, and reduce mechanical loss.

[0060] The placement groove 3 serves as a storage space for the solar panel 37. Through the partition design of the installation groove 31 and the through groove, the transmission components such as the screw and the belt are hidden in the groove, so that the solar panel 37 can be completely embedded in the placement groove 3 when folded, without taking up additional space, and maintaining the flatness of the top surface of the equipment.

[0061] The partitioned layout facilitates later maintenance: if the synchronous belt 36 or the screw fails, the components in the through groove and the mounting groove 31 can be directly accessed by removing the cover plate 16 of the placement groove 3, without disassembling the entire structure, thereby reducing the difficulty of maintenance.

[0062] This structure ensures the stability and power balance of the twin-screw synchronous transmission through the independent accommodation of the installation groove 31 and the exclusive transmission path design of the through groove, while optimizing the space utilization of the placement groove 3, reducing component interference and environmental corrosion, and ultimately improving the reliability of the deployment / folding of the solar panel 37 and the overall durability of the equipment, adapting to the requirements for equipment stability and convenience in emergency support scenarios.

[0063] In some embodiments, the air cooling module includes a mounting base 27, a first motor 28 and a circulation fan 29; the mounting base 27 is fixed on the side panel 26, the first motor 28 is installed on the mounting base 27, and the output shaft of the first motor 28 is connected to the circulation fan 29.

[0064] In this embodiment, the air cooling module includes a mounting base 27 , a first motor 28 and a circulation fan 29 . The mounting base 27 is fixed to the side plate 26 , and the first motor 28 drives the circulation fan 29 to operate.

[0065] In this solution, the first motor 28 and the circulation fan 29 are fixed by the mounting base 27 to ensure that the air-cooling module is firmly connected to the side plate 26; the first motor 28 directly drives the circulation fan 29, reducing power loss and improving heat dissipation efficiency.

[0066] The structure of the air cooling module has been clarified and optimized to ensure reliable heat dissipation. The module's installation stability and heat dissipation efficiency have been enhanced to ensure rapid and strong airflow after the side panels 26 are deployed, reducing device temperature.

[0067] In some embodiments, the air inlet direction of the circulation fan 29 forms an angle of 30°-45° with the plane of the corresponding side panel 26 .

[0068] In this embodiment, the air inlet direction of the circulation fan 29 forms an angle of 30°-45° with the plane of the side plate 26 .

[0069] If the circulation fan 29 draws air perpendicular to the side panels 26, the airflow may be concentrated in a certain area, limiting the heat dissipation range. This solution tilts the air intake direction by 30°-45°, allowing the airflow to cover a wider area of ​​the equipment (such as the gap between the side panels 26 and the three-phase power supply 1, and the equipment surface). This solution also directs the inflow of external cool air diagonally, enhancing air convection. This optimized airflow direction improves heat dissipation uniformity and coverage. This expanded heat dissipation area ensures more uniform temperatures across the equipment, preventing localized overheating and further enhancing heat dissipation.

[0070] In some embodiments, a PLC control panel 11 is embedded in the front of the three-phase power supply 1 ; the PLC control panel 11 is electrically connected to the synchronous motor 21 , the air cooling module, and the second motor 38 .

[0071] In this embodiment, a PLC control panel 11 is provided on the front of the three-phase power supply 1 . The PLC control panel 11 is electrically connected to the synchronous motor 21 , the air cooling module, and the second motor 38 .

[0072] In the above solution, each motor and module needs to be operated separately, which is inefficient and difficult to work in coordination (such as the linkage between the side panel 26 and the solar panel 37).

[0073] This solution centrally controls various components through the PLC control panel 11, which can start the heat dissipation and fan operation with one button, or synchronously control the expansion and heat dissipation of the solar panels 37 to achieve automated collaborative operation.

[0074] It solves the inefficiency of decentralized control and realizes intelligent integrated control. It simplifies the operation process, realizes the coordinated work of various functional modules, and improves the automation level and ease of use of the equipment.

[0075] In some embodiments, a temperature sensor is provided on the side wall of the three-phase power supply 1 , and the temperature sensor is connected to the PLC control panel 11 ; when the detection value of the temperature sensor exceeds a preset threshold, the PLC control panel 11 automatically starts the synchronous motor 21 and the air cooling module.

[0076] In this embodiment, a temperature sensor is provided on the side wall of the three-phase power supply 1 , and the temperature sensor is connected to the PLC control panel 11 . When the temperature exceeds a threshold, the synchronous motor 21 and the air cooling module are automatically started.

[0077] This solution uses a temperature sensor to monitor the ambient temperature in real time. When the temperature exceeds a preset value, the heat dissipation process (the side panels 26 are unfolded and the fan is running) is automatically triggered without manual intervention.

[0078] This achieves a closed-loop cooling system from passive monitoring to active response, preventing equipment failures caused by human negligence. This improves the device's intelligence, enabling rapid and automatic heat dissipation in high-temperature environments, minimizing the risk of downtime due to overheating and ensuring power supply stability.

[0079] In some embodiments, the mobile three-phase power emergency support device also includes a bracket 12, the three-phase power supply 1 is fixed on the bracket 12, and the four corners of the bottom surface of the bracket 12 are provided with abutment grooves 14, and a universal movable wheel 15 with a brake mechanism is installed in each of the abutment grooves 14; the rear end of the bracket 12 is fixedly connected to a U-shaped push rod 13.

[0080] In this embodiment, the three-phase power supply 1 is fixed to a bracket 12 . A universal movable wheel 15 with a brake is provided on the bottom surface of the bracket 12 , and a U-shaped push rod 13 is fixedly connected to the rear end.

[0081] Traditional three-phase power emergency support equipment is difficult to move, especially difficult to deploy quickly in complex terrains (such as construction sites and tunnels).

[0082] This solution achieves flexible steering through the universal moving wheels 15, the brake mechanism ensures stable parking, and the U-shaped push rod 13 is easy to push manually, so that the equipment can be quickly transferred to the target position.

[0083] This solves the problem of poor device mobility and improves deployment efficiency. It enhances the mobility and deployment flexibility of the device, adapts to the needs of rapid transfer in emergency scenarios, and expands the scope of application of the device (such as outdoor emergency repairs and temporary power supply points).

[0084] Those skilled in the art will clearly understand that, for the convenience and brevity of description, the specific working processes of the above-described equipment, devices and units can refer to the corresponding processes in the aforementioned method embodiments and will not be repeated here.

[0085] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
