Description

Technical Field

[0001] The present invention relates to the technical field of energy storage power stations, and in particular to a combined energy storage power station. Background Art

[0002] An energy storage power station is a power station that converts electrical energy into other forms of energy. It stores energy when electricity demand is low and releases it when demand is high to meet the operating needs of the power grid. The energy storage station uses electrochemical batteries to store, convert and release cyclical electrical energy. Its main function is to regulate peak and valley electricity consumption. The interior of the energy storage station is composed of a large number of stacked battery modules. In some areas with distinct winter and summer conditions, the batteries inside the energy storage station are at a low temperature in winter. At this time, no heat dissipation is required and even protective heating is required to ensure the operating temperature range of the battery. In summer, the battery modules with a higher density of arrangement inside the energy storage station have lower heat dissipation efficiency. Traditional energy storage stations have poor flexibility and cannot reduce their volume occupancy in winter. Summary of the Invention

[0015] The energy storage power station of the present invention is structurally configured to control battery clusters to move closer together in low-temperature winter environments to reduce heat loss and minimize the volume occupied by the energy storage power station. In high-temperature summer environments, the battery clusters are controlled to separate and increase spacing to facilitate air flow and cooling.

[0016] The system automatically enters a protective state when abnormal heating of the battery cluster is detected by the coordinated arrangement of the release gas pipe, compressed gas cylinder, and pre-closing gate. In the winter, when the battery clusters are close together, gas from the compressed gas cylinder is released through the release gas pipe, driving the pre-closing gate to move and close. The gas pressure then pushes the combined inner cover relative to the combined outer cover, thereby separating the battery clusters and increasing their spacing, reducing the impact between adjacent battery clusters in the event of thermal runaway. Simultaneously, the combined outer and inner covers are filled with inert, flame-retardant gas, which acts as work to cool them, significantly reducing their temperatures and entering a protective state. At this point, the system eliminates the need for actuating motors to drive the combined outer and inner covers, thus avoiding power outages caused by abnormal battery cluster heating. In the summer, when the battery clusters are already separated, the pre-closing gate is prevented from moving and closing. The release of gas from the compressed gas cylinder expels the air in the combined outer and inner covers through the breathing bottom holes, replacing it with inert, flame-retardant gas and rapidly reducing the temperature for protection. This allows for adaptive protection according to different winter and summer conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The limiting rail structure includes a cylindrical shaft 301, an upper inner rail 302, an upper outer rail 303, a lower inner clamping rail 304 and a lower outer clamping rail 305.

At this time, the cylindrical shaft 301 and the C-type battery rack 3 are in Figure 9 The horizontal direction shown in FIG is limited.

[0036] like Figure 10As shown in , the lower inner clamping rail 304 is fixedly mounted on the inner wall surface of the combined inner bin cover 2, the lower outer clamping rail 305 is arranged on the outside of the lower inner clamping rail 304, and one end of the lower outer clamping rail 305 is fixedly mounted on the combined outer bin cover 1, the lower inner clamping rail 304 is provided with a first clamping groove 306, and the lower outer clamping rail 305 is provided with a second clamping groove 307.

At this time, the cylindrical shaft 301 and the C-type battery holder 3 are in Figure 10 As shown in the figure, it is limited in the upper and lower directions, combined with the above-mentioned horizontal limit, so as to position and install the C-type battery rack 3, and the limiting track structure can adapt to the telescopic movement between the combined outer compartment cover 1 and the combined inner compartment cover 2, and the C-type battery rack 3 can slide along the limiting track structure through the cylindrical rotating shaft 301.

[0037] like Figure 14 As shown in the figure, an actuating motor 101 is fixedly provided inside the combined outer compartment cover 1, and an actuating screw 102 is transmission-connected to the actuating motor 101; a frame door fixing piece 103 is fixedly provided inside the combined inner compartment cover 2, and a split screw sleeve 104 is provided in the frame door fixing piece 103; the actuating screw sleeve 102 passes through the split screw sleeve 104 and is spirally matched with the split screw sleeve 104.

[0038] A release air pipe 105 is fixedly provided on one side of the frame door fixing piece 103, and the release air pipe 105 opens at one end away from the frame door fixing piece 103. An execution baffle 106 is provided in the release air pipe 105, a frame door lock hole 107 is provided in the frame door fixing piece 103, and a screw sleeve lock hole 108 is provided in the split screw sleeve 104. A locking pin 109 is fixedly provided on the execution baffle 106, and one end of the locking pin 109 is sealed and inserted through the end of the release air pipe 105, extending to the outside of the release air pipe 105, and then inserted through the frame door lock hole 107 and the screw sleeve lock hole 108 at the same time, so that the frame door fixing piece 103 and the split screw sleeve 104 are limited and fixed.

[0039] A limiting inner ring 110 is fixedly provided on the inner wall surface of the release air pipe 105, and the limiting inner ring 110 blocks and limits the execution baffle 106. An extension connecting rod 111 is fixedly provided on the open end of the release air pipe 105, and a connecting rod end plate 112 is fixedly provided on the end of the extension connecting rod 111.

[0040] A gate clamping edge 113 is fixedly provided on the inner lower surface of the combined outer warehouse cover 1, and a pre-closing gate 114 is provided in the sliding limit in the gate clamping edge 113. A right-angle push piece 115 is fixedly provided on the pre-closing gate 114. When the combined outer warehouse cover 1 and the combined inner warehouse cover 2 are retracted and brought into place, the right-angle push piece 115 will move to the end position of the release air pipe 105, so that the execution baffle 106 can push the right-angle push piece 115 to move when it moves axially, and the combined outer warehouse cover 1 A breathing bottom hole 116 is provided through the lower surface of the interior, and a dust-proof filter membrane 117 is provided in the breathing bottom hole 116. The dust-proof filter membrane 117 is used to filter and separate external dust when the breathing bottom hole 116 breathes. When the right-angle push piece 115 is pushed by the execution baffle 106, the pre-closing gate 114 will block the upper part of the breathing bottom hole 116. The breathing bottom hole 116 is often open during daily use, so that the air pressure can be balanced when the combined outer bin cover 1 moves relative to the combined inner bin cover 2.

[0041] A compressed gas cylinder 118 is fixedly installed in the combined inner chamber cover 2, and compressed flame-retardant gas is stored in the compressed gas cylinder 118. A gas relief duct 119 is provided to the outside of the compressed gas cylinder 118, and the other end of the gas relief duct 119 is connected to the release gas pipe 105. The gas relief duct 119 is provided with an electrically controlled gas valve 120 for controlling the on and off of the gas relief duct 119.

[0042] An independent protection battery 121 is fixedly installed in the combined inner compartment cover 2. The independent protection battery 121 has a charging function and is independent of the battery cluster 4. A temperature sensor is provided in the battery cluster 4. The independent protection battery 121 is used to power the temperature sensor and the electronically controlled air valve 120. When the temperature sensor detects a temperature higher than the set value, the electronically controlled air valve 120 is controlled to open.

[0043] The lower surface of the combined outer warehouse cover 1 is fixedly provided with a side strip support leg 122, and the lower surface of the combined inner warehouse cover 2 is fixedly provided with a roller support leg 201. The combined inner warehouse cover 2 is provided with an air-conditioning system 202, and the air-conditioning system 202 is used to regulate the temperature inside the combined outer warehouse cover 1 and the combined inner warehouse cover 2.

[0044] When the energy storage power station of the present invention is in use, the state is adjusted according to the ambient temperature; Figure 14 As shown in the figure, initially the split screw sleeve 104 and the frame door fixing member 103 are limited and fixed. When the action motor 101 drives the action screw 102 to rotate, the split screw sleeve 104 will move relative to the action screw 102, thereby driving the combined inner compartment cover 2 to move relative to the combined outer compartment cover 1.

[0045] In a low temperature environment, such as winter, the combined inner compartment cover 2 is retracted into the combined outer compartment cover 1, and the battery clusters 4 are squeezed together, as shown in FIG. Figure 4As shown in , the spacing between the battery clusters 4 is reduced, heat loss is reduced, and excessive cooling of the battery cluster 4 is avoided. More importantly, the volume of the energy storage power station can be reduced, so that the volume of an energy storage power station unit is smaller. It is well known that the heating power of the air conditioner is higher than that of the cooling power. When the power consumption of the air conditioner increases significantly in winter, by reducing the volume of the energy storage power station, more energy storage power station units can be accommodated to meet the needs of the power grid.

[0046] In a high temperature environment, such as in summer, the combined inner bin cover 2 is gradually moved out of the combined outer bin cover 1. Figure 4 and Figure 5 As shown in the figure, the associated vertical leaf 6 is pulled by fixing the wall nails 9 so that the combined inner compartment cover 2 and the combined outer compartment cover 1 are separated into place, and the battery clusters 4 are also pulled apart from each other, increasing the spacing to facilitate air flow and cooling.

[0047] In a low temperature environment, when the combined inner compartment cover 2 and the combined outer compartment cover 1 are in a state of being close to each other, Figure 14 As shown in the figure, the right-angle push piece 115 moves to the end position of the release gas pipe 105; when the temperature sensor set in the battery cluster 4 detects that a certain battery cluster 4 has abnormally heated up and exceeds the preset temperature, the feedback signal causes the independent protection battery 121 to power the electronically controlled gas valve 120. At this time, the electronically controlled gas valve 120 opens, and the compressed flame-retardant gas in the compressed gas cylinder 118 is input into the release gas pipe 105 through the gas release conduit 119.

[0048] like Figure 14As shown in , the gas first drives the execution baffle 106 to move axially, and the execution baffle 106 drives the locking pin 109 to move, so that the locking pin 109 is pulled out from the frame door lock hole 107 and the screw sleeve lock hole 108, and the split screw sleeve 104 is unlocked relative to the frame door fixing part 103. The two can move relatively, and the execution baffle 106 is pressed on the right-angle push piece 115, pushing the right-angle push piece 115 and the pre-closing gate 114 to move, so that the pre-closing gate 114 closes the breathing bottom hole 116. After the breathing bottom hole 116 is sealed, the enclosed space formed by the combined inner and outer chamber covers 2 and 1 is in a sealed state. When the flame-retardant gas is ejected through the release pipe 105, it fills the combined outer and inner chamber covers 1 and 2, increasing the air pressure in the combined outer and inner chamber covers 1 and 2. This air pressure pushes the combined inner chamber cover 2 to move relative to the combined outer chamber cover 1, separating the battery clusters 4 from each other. This increased spacing reduces the impact between adjacent battery clusters 4 in the event of thermal runaway. Furthermore, by filling the combined inner and outer chamber covers 2 and 1 with flame-retardant gas, the proportion of combustion-supporting gas in the combined inner and outer chamber covers 2 and 1 can be reduced, improving safety. Furthermore, according to the first law of thermodynamics, after the compressed gas is released, it expands and performs external work, reducing its internal energy and temperature. This rapidly cools the space within the combined inner and outer chamber covers 2 and 1, suppressing abnormal heating of the battery clusters 4. The above-mentioned movement of the combined inner chamber cover 2 is driven by air pressure, and no longer needs to be driven by the action motor 101, which can avoid the impact of power failure of the battery cluster 4. The action motor 101 is a high-power consumption device and needs to be connected to a power supply. When a failure occurs in the battery cluster 4, it is difficult to ensure stable power supply to the action motor 101.

[0049] If in a hot summer environment, the inner compartment cover 2 and the outer compartment cover 1 are already separated, and the distance between the battery clusters 4 has moved to the maximum, when an abnormal temperature rise of a battery cluster 4 is detected, the compressed gas cylinder 118 is also controlled to release gas, such as Figure 11 As shown in , at this time, the right-angle push piece 115 is separated from the release air pipe 105, and the execution baffle 106 no longer pushes the right-angle push piece 115 to move, so that the breathing bottom hole 116 will remain open, and the released flame-retardant gas enters the combined inner warehouse cover 2 and the combined outer warehouse cover 1, and the air originally in the combined inner warehouse cover 2 and the combined outer warehouse cover 1 will be squeezed out through the breathing bottom hole 116, while quickly cooling down for protection.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
