Description

Technical Field

[0001] The present invention relates to the field of inverter energy storage, and in particular to a new energy grid-connected inverter energy storage device. Background Art

[0002] A grid-tied inverter is a special inverter that can convert DC power to AC power. In addition to converting DC power to AC power, its output AC power can be synchronized with the frequency and phase of the mains power, so the output AC power can be returned to the mains power. Grid-tied inverters are often used in applications where a DC voltage source is connected to the grid. The inverter converts DC power to AC power so that it can be sent back to the grid. The frequency of the output voltage of the grid-tied inverter must be the same as the grid frequency, which is generally achieved using an oscillator in the machine, and the output voltage is also limited to not exceed the grid voltage. Modern high-quality grid-tied inverters can have an output power factor of 1, indicating that the phase of the output voltage and current are the same, and the phase difference between them and the grid voltage is within 1 degree. The inverter contains a microprocessor that can sense the AC waveform of the grid and generate voltage based on this waveform to send back to the grid.

[0003] For example, the invention with application number CN119297516A discloses a new energy storage device, which includes an isolation box, a battery box and a control box arranged in sequence, a partition is arranged in the battery box, a plurality of first straps are arranged on both sides of the partition, a plurality of second straps are arranged on both sides of the battery box, the second straps correspond to the positions of the first straps, battery modules are placed on the first straps and the second straps, a first connecting plate is arranged adjacent to the battery box and the control box shown, a plurality of conductive seats are arranged on the first connecting plate, and the conductive seats are correspondingly connected to the conductive heads of the battery modules; however, this application still has many shortcomings, such as: 1) When using cooling and fire extinguishing components to cool down and extinguish overheated battery modules, there are two major problems: on the one hand, when the blocking plate is not completely sealed, the flames and carbon dioxide It may leak along the edge of the sealing plate, causing baking of adjacent normal battery modules, thereby affecting their normal operation and increasing the probability of fire; on the other hand, when the sealing plate is completely sealed, as carbon dioxide is continuously injected, the air pressure in the isolation box will gradually increase, forming a pressure difference with the outside world, which not only increases the difficulty of subsequent processing by the staff, but also because there is still a large amount of air in the isolation box, the burning battery needs to consume all the oxygen before it can be extinguished, resulting in low fire extinguishing efficiency; 2) Batteries will produce toxic gases such as HF, CO and other harmful chemicals when they burn under extreme conditions. Once these substances are released into the environment, they will not only pose a direct threat to the health of surrounding people, but long-term exposure may also cause serious respiratory damage or other health problems.

[0037] Through the above technical features: after the abnormal battery 4 is placed in the isolation box 28, the carbon dioxide cylinder continuously introduces carbon dioxide into the ventilation cavity 49 through the installation head 48, and then sprays it into the isolation box 28 through the nozzle. At this time, under the action of air pressure, the air in the isolation box 28 and the harmful gases generated by the abnormal battery 4 are discharged through the constant pressure window 52. The harmful smoke generated by the combustion of the battery 4 is treated with activated carbon, acid and alkali solution, and the harmful gas treatment is completed, and then the harmless gas is discharged to avoid affecting the health of surrounding personnel. At the same time, the air in the isolation box 28 is discharged and filled with carbon dioxide, thereby achieving the purpose of fire extinguishing. Moreover, during the fire extinguishing process, the air pressure in the isolation box 28 is the same as the external air pressure, and there will be no pressure difference, which is convenient for subsequent processing by the staff and improves the fire extinguishing efficiency.

[0038] In order to move the isolation box 28 to the position of the abnormal battery 4, a lifting mechanism is set up. The lifting mechanism includes two adjustment slots 51 arranged on the side wall of the frame group 1.

The two lifting blocks 27 are respectively slidably connected to the inner walls of the two adjustment slots 51, and the two lifting blocks 27 are fixedly connected to the isolation box 28.

[0039] Through the above technical features: when the temperature sensor detects that the current battery 4 is abnormal, the traction rope 3 is driven to wind through the second motor 26, and the traction rope 3 drives the isolation box 28 to rise and fall through the lifting block 27 until the isolation box 28 moves to the abnormal battery 4. The position of the abnormal battery 4 can be accurately identified and isolated according to the temperature sensor corresponding to the abnormal battery 4, and the abnormal battery 4 can be accurately positioned.

[0040] In order to move the abnormal battery 4 into the isolation box 28, a pushing mechanism is provided. The pushing mechanism includes a base plate 8 mounted on the frame group 1, a driving slot 9 is provided on the base plate 8, a driving shaft 38 is rotatably connected in the driving slot 9, and a second transmission shaft 39 is provided through the frame group 1. One end of the second transmission shaft 39 is fixedly connected to a mortise 40. The driving shaft 38 and the second transmission shaft 39 are connected through a transmission gear set 41. It should be noted that the transmission gear set 41 includes a third bevel gear 42 and a fourth bevel gear 43 that mesh with each other.

The isolation box 28 is provided with a vertical groove 47 that matches the mortise 40 and the tenon 17.

[0041] According to the above technical features: when the isolation box 28 moves to the position of the abnormal battery 4, the tenon 17 is engaged with the corresponding mortise 40, the first motor 14 is started and drives the driving shaft 10 to rotate, the driving shaft 10 drives the outer ring 18 to rotate through the inner ring 19, and the outer ring 18 drives the conveyor belt 12 to rotate. At the same time, the driving shaft 10 drives the first transmission shaft 13 to rotate, the first transmission shaft 13 drives the second transmission shaft 39 to rotate through the tenon 17 and the mortise 40, the second transmission shaft 39 drives the push shaft 38 to rotate, the push shaft 38 drives the pull rope 45 to reel through the winding wheel 44, the pull rope 45 pulls the push plate 5 to move through the L-shaped rod 46, and the push plate 5 The battery 4 can be pushed to the appropriate position in the isolation box 28. At this time, the battery 4 is located on the conveyor belt 12, and then the first motor 14 rotates in the opposite direction, driving the inner ring 19 to rotate in the opposite direction.

The pull rope 45 is loosened, and the L-shaped rod 46 is reset under the action of the reset spring until it reaches the appropriate position. Then the first motor 14 is rotated forward. At this time, the conveyor belt 12 transports the battery 4 until the battery 4 is located in the appropriate position in the isolation box 28. The abnormal battery 4 can be automatically positioned and removed from the frame group 1 for isolation to prevent the abnormal battery 4 from affecting the normal battery 4.

[0042] In order to isolate the overheated or catching fire battery 4, an isolation mechanism is provided. The isolation mechanism includes a groove 50 provided at the bottom of the isolation box 28. Two driving shafts 10 are rotatably connected in the groove 50. A first motor 14 is installed outside the isolation box 28. The drive shaft of the first motor 14 rotates through the isolation box 28 and is coaxially connected to the driving shaft 10.

[0044] Through the above technical features: when the abnormal battery 4 is placed in the isolation box 28, the two lifting shafts 32 are driven to rotate by the third motor 37, the lifting shafts 32 drive the lifting gears 33 to rotate, and the lifting gears 33 drive the isolation door 29 to rise and fall, and the isolation door 29 closes the isolation box 28. At this time, the battery 4 can be isolated and extinguished by carbon dioxide, and the fire extinguishing effect on the abnormal battery 4 is better.

[0045] Working principle:

[0046] Monitor abnormal battery 4 and isolate it: When the temperature sensor detects that the current battery 4 is abnormal, the traction rope 3 is driven to wind through the second motor 26, and the traction rope 3 drives the isolation box 28 to rise and fall through the lifting block 27 until the isolation box 28 moves to the abnormal battery 4. At this time, the tenon 17 is engaged with the corresponding mortise 40, and the first motor 14 is started and drives the driving shaft 10 to rotate. The driving shaft 10 drives the outer ring 18 to rotate through the inner ring 19, and the outer ring 18 drives the conveyor belt 12 to rotate. At the same time, the driving shaft 10 drives the first transmission shaft 13 to rotate, and the first transmission shaft 13 rotates through the tenon 17 and the mortise 40, and the mortise 40 drives the second transmission shaft 39 to rotate, and the second transmission shaft 39 The push shaft 38 is driven to rotate, and the push shaft 38 drives the pull rope 45 to be wound through the winding wheel 44. The pull rope 45 pulls the push plate 5 to move through the L-shaped rod 46, and the push plate 5 can push the battery 4 to the appropriate position in the isolation box 28. At this time, the battery 4 is located on the conveyor belt 12, and then the first motor 14 rotates in the opposite direction, driving the inner ring 19 to rotate in the opposite direction. At this time, the ratchet 21 will rotate along the surface of multiple teeth 20, and will not drive the teeth 20 to rotate, and the pull rope 45 is loosened. The L-shaped rod 46 is reset under the action of the reset spring until it reaches the appropriate position, and then the first motor 14 is rotated forward. At this time, the conveyor belt 12 transports the battery 4 until the battery 4 is located in the appropriate position in the isolation box 28.

[0047] Extinguishing fire of abnormal battery 4: When the abnormal battery 4 is placed in the isolation box 28, the two lifting shafts 32 are driven to rotate by the third motor 37, the lifting shaft 32 drives the lifting gear 33 to rotate, and the lifting gear 33 drives the isolation door 29 to rise and fall, and the isolation door 29 closes the isolation box 28. At this time, the carbon dioxide cylinder continuously introduces carbon dioxide into the ventilation cavity 49 through the mounting head 48, and the carbon dioxide is then sprayed into the isolation box 28 through the nozzle. At this time, under the action of air pressure, the air in the isolation box 28 and the harmful gases generated by the abnormal battery 4 are discharged through the constant pressure window 52. The harmful flue gas generated by the combustion of the battery 4 is treated with activated carbon, acid and alkali solution, and the harmful gas treatment is completed. The treated gas is then discharged through the outlet pipe 54, so that the air in the isolation box 28 is discharged and filled with carbon dioxide, thereby achieving the purpose of fire extinguishing.
