Description

Technical Field

[0001] The present invention relates to the technical field of temporary power supply cabinets, in particular to a temporary power supply cabinet integrated with an intelligent system for preventing power outages. Background Art

[0002] As we all know, power supply cabinets are mainly used to control, distribute, and protect electrical energy after being connected to the mains. Temporary power supply cabinets are often used outdoors or on vehicles to solve power supply problems in short-term, emergency, or mobile scenarios, including but not limited to construction sites, outdoor exhibitions, disaster relief sites, and other scenarios.

[0003] The existing technology has the following problems: Although the existing temporary power supply cabinet can provide external mains power control and distribution to electrical appliances in various mobile scenarios, it cannot provide continuous power supply to major electrical appliances in locations where mains power cables are difficult to reach or in the event of an emergency power outage, and its functionality is relatively limited.

[0004] Based on the above-mentioned situation, we found that it is difficult to avoid the above problems with the temporary power supply cabinets of the existing technology. Therefore, we proposed a temporary power supply cabinet that integrates temporary power generation and long-term power storage. It can still provide power guarantee for major electrical appliances when the mains power is cut off. At the same time, it optimizes the heat dissipation requirements of the power supply cabinet so that it can change the heat dissipation mode according to the mains power or temporary power supply. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the present invention provides a temporary power supply cabinet with an integrated intelligent system that is resistant to power outages. It has the advantages of integrated temporary power generation and long-term power storage, which can still provide power supply guarantee for major electrical appliances when the mains power is cut off, and at the same time optimize the heat dissipation requirements of the power supply cabinet, so that it can change the heat dissipation mode according to the mains power or temporary power supply.

[0007] (2) Technical solution

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: a temporary power supply cabinet with intelligent system integration and anti-power outage protection, comprising a base cabinet, a power cabinet fixedly connected to the top of the base cabinet, a power module installed on the inside of the power cabinet, a diesel generator and a power storage device installed on the bottom of the inside of the power cabinet, a side cover installed on the right side of the power cabinet by bolts and nuts, and a heat dissipation structure provided on the inside of the side cover;

[0009] The heat dissipation structure includes an active frame and a driven frame, the tops of the active frame and the driven frame are fixedly connected to the right side of the inner wall of the power cabinet through a metal frame, the top of the active frame is provided with matching teeth, the outer side of the active frame is fixedly connected to a hollow frame, the inner side of the hollow frame is rotatably connected to two groups of limiting rollers, the limiting rollers are in contact with the bottom of the active frame, the inner side of the hollow frame is rotatably connected to a gear, the gear and the matching teeth are meshed, the front side of the hollow frame is fixedly connected to a control motor, the output end of the control motor passes through the hollow frame and is fixedly connected to the gear, and the rear side of the hollow frame is fixedly connected to a cooling fan;

[0010] A heat exchange pipe is provided on the inner side of the side cover, a bracket is installed on the outer side of the power cabinet, a photovoltaic panel assembly is installed on the inner side of the bracket, and a support is provided on the bottom of the bottom cabinet.

[0011] By adopting the above technical solution, two spaces are separated by setting up a bottom cabinet and a power cabinet. The horizontal area of ​​the bottom space is larger and is used to install a diesel generator and a storage device. When emergency power supply is needed, temporary power supply can be provided by the diesel generator or the power stored in the power module can be used to ensure that the main electrical appliances will not be cut off. Among them, the municipal power supply as the external main power source and the storage device as the backup power source are connected through an intelligent switching module. When the power is cut off, it automatically switches within 0.1 second to ensure continuous power supply to the equipment. The built-in MCU controller monitors the voltage of the municipal power and the power of the storage device in real time, and optimizes the charging and discharging logic through an algorithm to avoid damage to the battery by excessive discharge. The voltage sensor installed in the power module monitors the main power supply in real time. When the voltage is lower than the set threshold, the relay automatically disconnects the municipal power as the main power source and connects the backup power source to ensure that there is no flash during the switching process. When the main power supply is normal, the municipal power as the main power source cooperates with the photovoltaic power generation of the photovoltaic panel assembly to power the electrical appliances while supplying power to the storage device. The electrical device is charged, and the heat dissipation structure arranged on the inner side of the side cover is used to dissipate heat for the components inside the base cabinet or the power cabinet through airflow. During normal operation, the air outlet direction of the cooling fan is to the left, and the power module components inside the power cabinet are cooled by the airflow. Low-temperature coolant is passed into the heat exchange tube, so that the blown airflow further reduces the temperature and improves the heat dissipation effect. When the main power supply is cut off, the diesel generator and the storage device supply power to the electrical appliances. At this time, the components inside the base cabinet are operating, so the cooling demand inside the base cabinet is higher than that inside the power cabinet after the power is cut off. Therefore, the motor drive gear is controlled to rotate. The active frame connected to it by mating teeth is arc-shaped, so when the driving gear moves along the mating teeth, it will drive the hollow frame connected to it to move. At the same time, the limit roller limits the position of the active frame relative to the hollow frame to prevent the structure from loosening. When it rotates to the bottom of the active frame, the air outlet direction of the cooling fan is the bottom side to assist in heat dissipation inside the base cabinet.

[0012] The present invention is further configured as follows: the side cover includes a front side plate, the front side plate includes an arc-shaped portion at the top and a flat plate portion on the front side, the right side of the front side plate is fixedly connected with a mesh plate portion, the inner side of the mesh plate portion is provided with mesh holes, the rear side of the front side plate is provided with an equipment plate, and the left side of the equipment plate is installed with a power cabinet by bolts and nuts.

[0013] By adopting the above technical solution, by setting the front side panel as the main body of the side cover, the top and front position of the right side of the power cabinet can be shielded and protected at the same time, and the curved top design can facilitate sliding down in rainy and snowy weather or when impurities fall. The provided mesh plate is used to allow air flow to normally enter the interior of the front side panel, and the provided equipment plate is separately connected to the power cabinet and can be used to install the mounted components. When other parts of the side cover are disassembled and assembled, it is not easy to affect the components installed thereon.

[0014] The present invention is further configured as follows: a movable groove is provided on the right side of the power supply cabinet, the movable groove is provided on the outside of the heat dissipation structure, a wire groove is provided on the top of the base cabinet, a limit frame is fixedly connected to the top of the base cabinet, a retaining frame is inserted into the inner side of the limit frame, a brush is provided on the inner side of the retaining frame, and a circulation groove is provided on the top of the base cabinet.

[0015] By adopting the above technical solution, by setting up a movable groove, the components of the heat dissipation structure can be moved, and at the same time serve as an airflow inlet. The set wire groove is used for the passage of cables when the power module and the diesel generator or the storage device are connected by cables, and the setting of the brush can allow the cables to pass freely while blocking the wire groove opening, so that the power cabinet and the base cabinet remain relatively isolated.

[0016] The present invention is further configured as follows: a tension spring is fixedly connected to the top of the limit frame, a sleeve is fixedly connected to the top of the tension spring, and the bottom of the sleeve passes through the limit frame and is plugged into the blocking frame.

[0017] By adopting the above technical solution, a baffle is set as a carrier of the brush, and it can be quickly disassembled and assembled by sliding into the limit frame. During installation, the sleeve can be pulled up along the tension spring, and after the baffle is inserted into the isolation frame, the sleeve passes through the limit groove through the rebound of the tension spring and limits the baffle to prevent it from displacement or loosening, which makes it easy to disassemble and assemble.

[0018] The present invention is further configured as follows: an inverter and a solar controller are fixedly connected to the front side of the equipment panel, and the inverter, solar controller, photovoltaic panel assembly and power storage device are electrically connected.

[0019] By adopting the above technical solution, by setting up an inverter in conjunction with a solar controller, the photovoltaic panel assembly converts light energy into DC electricity through the photovoltaic effect, which is then managed by the solar controller to charge the storage device. The controller can implement overcharge and over-discharge protection and MPPT maximum power tracking to improve efficiency.

[0020] The present invention is further configured as follows: a water tank, a liquid pump and a heat exchanger are installed on the front side of the equipment plate, the two ends of the heat exchange tube are respectively connected to the liquid pump and the water tank, and the input and output ends of the heat exchanger are respectively connected to the liquid pump and the water tank.

[0021] The above technical solution is adopted, by setting up a water tank for storing liquid used as refrigerant, and the liquid pump provides power to push the liquid to circulate in the system. When the liquid flows into the heat exchanger after being pressurized by the liquid pump, it will exchange heat with the air flow passing outside the pipe in the heat exchange tube inside the heat exchanger. The air flow transfers heat to the cold fluid through the wall of the heat exchange tube to lower its own temperature, making the air flow temperature more suitable for heat dissipation. The liquid that completes the heat exchange flows back to the water tank.

[0022] The present invention is further configured as follows: a wheel frame is provided on the outer side of the driven frame, four driven wheels are rotatably connected to the inner side of the wheel frame, and an arc-shaped concave is provided on the side of the driven wheel close to the driven frame that matches the outer contour of the driven frame. The inner side of the driven wheel is in contact with the driven frame, and the front side of the wheel frame is fixedly connected to the cooling fan.

[0023] By adopting the above technical solution, a wheel frame is set to cooperate with the driven wheel, so that the driven frame can move along the driven frame to support and limit the force on the rear side of the cooling fan. When the cooling fan is driven to move by the front structure, the wheel frame and driven wheel on the rear side will also slide along the driven frame.

[0024] The present invention is further configured as follows: a lower frame is provided on the inner side of the support, the top of the lower frame is fixedly connected to the bottom of the base cabinet, the top and bottom of the lower frame are fixedly connected to support springs, and the side of the support spring away from the lower frame is fixedly connected to the support.

[0025] The above technical solution is adopted by setting a lower frame and a support spring to connect the support and the base cabinet. There is a certain gap between the lower frame and the support for air circulation. The support spring supports the connection between the support and the base cabinet. When the force of the placement device is too large, the support spring can be deformed to achieve a buffering effect, thereby reducing damage to the structure or the occurrence of loose internal connection cables.

[0026] The present invention is further configured as follows: a limit rod is fixedly connected to the inner side of the support, the outer side of the limit rod is slidably connected to the down frame, the limit rod is arranged on the inner side of the support spring, and an airbag is installed between the down frame and the support.

[0027] By adopting the above technical solution, a limit rod is set to limit the movement between the support and the down frame, which can avoid radial displacement between the structures and cause unstable center of gravity. The set airbag can assist in supporting and cushioning the support and the down frame.

[0028] The present invention is further configured as follows: the power module includes but is not limited to a power switching device, a circuit breaker, a leakage protector, a branch terminal, a main power interface and a voltage sensor.

[0029] With the above technical solution, in the power module, after the main power interface is connected to the mains, it is first protected against overload and short circuit by the circuit breaker, and then the leakage protector is used to monitor the leakage to ensure the safety of the main circuit. Subsequently, the electric energy is distributed to each branch through the branch terminal, and the voltage sensor monitors the voltage in real time. When the main power supply is abnormal, the power switching device is triggered to automatically disconnect the main power supply and connect the storage device as a backup power supply, realizing temporary power switching and ensuring continuous power supply to electrical appliances.

[0030] (3) Beneficial effects

[0031] Compared with the prior art, the present invention provides a temporary power supply cabinet with intelligent system integration and power outage prevention, which has the following beneficial effects:

[0032] The temporary power supply cabinet integrated by the intelligent system for preventing power outages is separated into two spaces by setting up a bottom cabinet and a power cabinet. The bottom space has a larger horizontal area and is used to install a diesel generator and a storage device. When emergency power supply is needed, temporary power supply can be provided by the diesel generator or the power stored in the power module can be used to ensure that the main electrical appliances will not be cut off. Among them, the municipal power supply as the external main power source and the storage device as the backup power source are connected through an intelligent switching module. In the event of a power outage, they automatically switch within 0.1 second to ensure continuous power supply to the equipment. The built-in MCU controller monitors the voltage of the municipal power and the power of the storage device in real time, optimizes the charging and discharging logic through an algorithm to avoid damage to the battery due to excessive discharge. The voltage sensor installed in the power module monitors the main power supply in real time. When the voltage is lower than the set threshold, the relay automatically disconnects the municipal power as the main power source and connects the backup power source to ensure that there is no flash during the switching process. When the main power supply is normal, the municipal power as the main power source cooperates with the photovoltaic power generation of the photovoltaic panel assembly to power the electrical appliances. At the same time, the storage device is charged. The heat dissipation structure arranged on the inside of the side cover is used to dissipate heat for the components inside the bottom cabinet or the power cabinet through airflow. During normal operation, the air outlet direction of the cooling fan is to the left, and the power module components inside the power cabinet are cooled by the airflow. Low-temperature coolant is passed into the heat exchange tube, so that the blown airflow further reduces the temperature and improves the heat dissipation effect. When the main power supply is cut off, the diesel generator and the storage device supply power to the electrical appliances. At this time, the components inside the bottom cabinet are operating, so the cooling demand inside the bottom cabinet is higher than that inside the power cabinet after the power is cut off. Therefore, the motor drive gear is controlled to rotate. The active frame connected to it by mating teeth is arc-shaped. Therefore, when the driving gear moves along the mating teeth, it will drive the hollow frame connected to it to move. At the same time, the limit roller limits the position of the active frame relative to the hollow frame to prevent the structure from loosening. When it rotates to the bottom of the active frame, the air outlet direction of the cooling fan is the bottom side to assist in heat dissipation inside the bottom cabinet.

[0048] Example 2

[0049] refer to Figure 1-5, a temporary power supply cabinet with intelligent system integration for preventing power outages also includes a heat dissipation structure 7, wherein the heat dissipation structure 7 includes an active frame 71 and a driven frame 72, the tops of the active frame 71 and the driven frame 72 are fixedly connected to the right side of the inner wall of the power cabinet 2 through a metal frame, the top of the active frame 71 is provided with matching teeth, the outer side of the active frame 71 is fixedly connected to a hollow frame 74, the inner side of the hollow frame 74 is rotatably connected to two groups of limiting rollers 73, the limiting rollers 73 are in contact with the bottom of the active frame 71, the inner side of the hollow frame 74 is rotatably connected to a gear, the gear and the matching teeth are meshed, the front side of the hollow frame 74 is fixedly connected to a control motor, the output end of the control motor passes through the hollow frame 74 and is fixedly connected to the gear, and the rear side of the hollow frame 74 is fixedly connected to a cooling fan 75;

[0050] The heat dissipation structure 7 arranged on the inner side of the side cover 6 is used to dissipate heat from the components inside the base cabinet 1 or the power cabinet 2 through airflow. During normal operation, the air outlet direction of the cooling fan 75 is to the left, and the power module 3 components inside the power cabinet 2 are cooled by the airflow. The low-temperature coolant is passed into the heat exchange tube 8, so that the blown airflow further reduces the temperature and improves the heat dissipation effect. When the main power supply is cut off, the diesel generator 4 and the power storage device 5 supply power to the electrical appliances. At this time, the components inside the base cabinet 1 are operating, so the cooling demand inside the base cabinet 1 is higher than that inside the power cabinet 2 after the power is cut off. Therefore, the motor drive gear is controlled to rotate. The active frame connected to it by mating teeth is arc-shaped. Therefore, when the driving gear moves along the mating teeth, it will drive the hollow frame 74 connected to it to move. At the same time, the limiting roller 73 limits the position of the active frame 71 relative to the hollow frame 74 to prevent the structure from loosening. When it rotates to the bottom of the active frame 71, the air outlet direction of the cooling fan 75 is the bottom side to assist in heat dissipation inside the base cabinet 1.

[0051] Among them, a wheel frame 18 is provided on the outer side of the driven frame 72, and four driven wheels 19 are rotatably connected on the inner side of the wheel frame 18. The driven wheel 19 is provided with an arc-shaped concave on the side close to the driven frame 72 that matches the outer contour of the driven frame 72. The inner side of the driven wheel 19 contacts the driven frame 72, and the front side of the wheel frame 18 is fixedly connected to the cooling fan 75. By setting the wheel frame 18 to cooperate with the driven wheel 19, the driven frame 72 can move along the driven frame 72 to support and limit the force on the rear side of the cooling fan 75. When the cooling fan 75 is driven to move by the front structure, the wheel frame 18 and the driven wheel 19 on the rear side will also slide along the driven frame 72.

[0052] The working principle of this embodiment is as follows: the direction of the fan is adjusted by the cooperation of the active frame 71 and the driven frame 72 to adapt to the heat dissipation requirements under different power supply modes. The matching teeth on the top of the active frame 71 are engaged with the gear. When the motor drives the gear to rotate, the active frame 71 is an arc-shaped structure, which drives the hollow frame 74 to move along the track of the active frame 71. The limiting roller 73 on the inside of the hollow frame 74 is close to the bottom of the active frame 71 to prevent the structure from loosening. When the mains power is supplied normally, the fan is located on the upper part of the active frame 71 and blows air to the left to cool the inside of the power cabinet 2. The power module 3 and the low-temperature coolant in the heat exchange tube 8 exchange heat with the air flow to further cool the machine; when the mains power is cut off, the diesel generator 4 starts, and the control motor drives the gear to move along the mating teeth to the bottom of the active frame 71. The fan turns to the lower side to dissipate heat for the diesel generator 4 in the base cabinet 1. The wheel frame 18 on the outside of the driven frame 72 contacts the driven frame 72 through four driven wheels 19 with arc-shaped concave shapes. When the fan moves with the hollow frame 74, the driven wheels 19 roll along the outer contour of the driven frame 72 to provide support and limit for the rear side of the fan.
