Description

Technical Field

[0001] The utility model relates to the technical field of energy storage systems, and in particular to an energy storage power station system in a cold and heat co-storage mode. Background Art

[0002] Domestic new energy is developing rapidly, and the proportion of new energy (photovoltaic and wind power) is gradually increasing. Due to the limitations of the forms and conditions of new energy power generation, they do not have particularly strong peak-shaving capabilities (photovoltaic power generation during the day). In some areas, daytime electricity consumption is not that high, so these photovoltaics have to be disconnected from the grid and stop generating electricity, wasting natural resources and power generation resources in vain.

[0003] However, the current mainstream energy storage method is chemical battery energy storage (mainly lithium iron phosphate). The charging and discharging efficiency of lithium iron phosphate is about 92%, and the energy storage efficiency is only 85%. Because it is a chemical battery, a large amount of heat is released during the charging and discharging process. The accumulation of this heat will cause the battery temperature to rise, posing a serious natural risk. Currently, a 35kW (taking the mainstream 5MWH 20-foot energy storage cabin as an example) chiller is configured in the energy storage cabin, using 50% ethylene glycol solution as a cold circulation carrier to absorb the heat from the battery, and then directly discharge it with the chiller, resulting in serious energy waste.

It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the present invention.

[0016] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0017] See also Figure 1 and Figure 2 The present invention provides a heat and cold co-storage energy storage power station system, the heat and cold co-storage energy storage power station system comprising:

[0018] A base plate 1 and an energy storage bin 2, grooves and openings are provided on both sides of the energy storage bin 2, and the energy storage bin 2 is installed on the base plate 1; an energy storage battery 3 is installed in the energy storage bin 2 for supplying power to the outside; an energy storage mechanism 4 is installed on the base plate 1 and arranged on both sides of the energy storage bin 2, and the energy storage mechanisms 4 on both sides are respectively used to store heat and cold, and an exhaust mechanism 5 is connected between the energy storage mechanism 4 and the energy storage bin 2; an opening and closing mechanism 6 is installed on the inner wall of the energy storage bin 2 and is arranged in conjunction with the opening, and is used to control the opening and closing of the opening opened in the energy storage bin 2, and a filter screen 7 is provided in the groove opened in the energy storage bin 2, and a clamping mechanism 8 installed on the energy storage bin 2 is provided on one side of the filter screen 7.

[0019] When using the energy storage power station system with the cold and heat co-storage mode, the energy storage liquid is first added to the energy storage mechanism 4. The energy storage liquids added to the energy storage mechanisms 4 on both sides are cold storage liquid and heat storage liquid respectively. When the temperature is high in summer, the exhaust mechanism 5 connected to the energy storage mechanism 4 filled with heat storage liquid is driven, and the heat generated by the energy storage battery 3 can be introduced into the heat storage liquid of the energy storage mechanism 4 through the exhaust mechanism 5 for storage, thereby realizing heat dissipation of the energy storage battery 3. At the same time, the cold capacity of the energy storage mechanism 4 filled with cold storage liquid can be supplied to other places for use. In winter, the temperature of the energy storage battery 3 is low, and the exhaust mechanism 5 connected to the energy storage mechanism 4 filled with cold storage liquid is turned on to extract the cold capacity on the energy storage battery 3 into the cold storage liquid for storage. At the same time, the heat of the energy storage mechanism 4 filled with heat storage liquid can be supplied to other places for use.

[0020] like Figure 1 As shown, as a preferred embodiment of the present utility model, the energy storage mechanism 4 includes: a box body 41, which is fixedly mounted on the bottom plate 1 and arranged on both sides of the energy storage bin 2, a feeding hopper 42 is installed on the upper end of the box body 41, and the energy storage liquid can be added into the box body 41 by the feeding hopper 42, and a discharge pipe 43 for discharging the energy storage liquid is fixed on the lower side of the box body 41; an air inlet pipe 44, which is fixedly mounted on the box body 41, and a filter plate 45 is installed at the air inlet end of the air inlet pipe 44, and the air outlet end of the air inlet pipe 44 extends to the lower side of the box body 41; an energy supply pipe 46, which is fixedly mounted on the upper side of the box body 41, and a drive pump 47 is installed on the energy supply pipe 46 for taking the energy of the energy storage liquid for energy supply.

[0021] Energy storage liquid can be added from the hopper 42 to the box body 41 for storage, and the energy storage liquid can be discharged from the discharge pipe 43. Cold and heat can be drawn into the box body 41 by the exhaust mechanism 5 for storage. When performing functions in other places, the driving pump 47 is turned on. The driving pump 47 drives the external air to flow into the box body 41 through the air inlet pipe 44 after being filtered by the filter plate 45. After taking away the cold or heat, it flows into other places through the energy supply pipe 46, thereby supplying cold or heat to other places.

[0023] When exhausting, the fan 53 is turned on. The power source of the fan 53 is a motor. The fan 53 drives the cold or heat on the energy storage battery 3 to flow from the air collecting hopper 54 through the connecting pipe 51 and the insertion pipe 55 to the dispersion plate 56, and finally flows out from the dispersion holes opened by the dispersion ball 57. The cold or heat can be stored in the cold storage liquid and the heat storage liquid.

[0024] like Figure 3 As shown, as a preferred embodiment of the present invention, the opening and closing mechanism 6 includes: a guide sleeve 61, which is fixedly mounted on the inner wall of the energy storage bin 2 and distributed on both sides of the opening, and a limit plate 62 is slidingly arranged in the guide sleeve 61 on both sides, and a guide rod 63 is fixedly arranged on the limit plate 62, and a push spring 64 is fixedly connected between the limit plate 62 and the inner wall of the guide sleeve 61 for pushing the guide rod 63 to slide along the guide sleeve 61; a connecting plate 65, which is fixedly connected to the guide rods 63 on both sides, and a sealing plug 66 is fixedly arranged on the connecting plate 65, and the sealing plug 66 is used to control the opening and closing of the opening.

[0025] When extracting cold or heat from the energy storage battery 3, under the action of negative pressure, the sealing plug 66 can drive the guide rod 63 and the limit plate 62 to slide along the guide sleeve 61 and compress the push spring 64. After the sealing plug 66 is separated from the opening, the air flow can flow into the energy storage bin 2 through the opening, and the filter 7 can filter the air flow. When the extraction stops, the push spring 64 can drive the sealing plug 66 to close the opening.

[0027] If the filter 7 is to be replaced, pull the handle 85, which drives the slide 83 and the pressure block 86 to move and compress the compression spring 84. After the pressure block 86 is separated from the filter 7, the filter 7 can be replaced. After the replacement is completed, release the handle 85, and the compression spring 84 can push the pressure block 86 to press the filter 7 tightly into the groove.
