However, there is no finished hybrid energy storage system available in the market today. Therefore, this application proposes a hybrid energy storage system to meet the market demand. Summary of the Invention

[0003] The purpose of the present invention is to provide a hybrid energy storage system to solve the problem of providing a hybrid energy storage system to meet the market demand as proposed in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A hybrid energy storage system includes an energy storage box, a bottom layer structure and a top layer structure located above the energy storage box. One side of the top of the energy storage box is an inclined surface for facilitating the inclination of a solar panel, and a storage compartment is provided on the side of the energy storage box away from the inclined surface. The above bottom layer structure includes: Four struts distributed in a rectangular array on the inclined surface of the energy storage box; First clamping plates at the tops of the four struts; The above top layer structure includes: Second clamping plates located on the top of the first clamping plates; Four shielding blocks installed on the two symmetric sides of the second clamping plates and distributed in a rectangular array.

[0005] As a preferred embodiment of the present invention, ventilation grooves for facilitating air flow are provided on both symmetric sides of the energy storage box, and four legs distributed in a rectangular array for supporting the energy storage box are fixed at the bottom.

[0006] As a preferred embodiment of the present invention, an energy storage battery matching the shape of the storage compartment is installed in the above storage compartment of the energy storage box, and a sealing plate for protecting the energy storage battery is installed at the storage compartment of the energy storage box.

[0007] As a preferred embodiment of the present invention, a first groove is formed at the center of the top of the first engaging plate, and four engaging blocks are fixed on the two opposite side walls of the first engaging plate and are distributed in a rectangular array.

[0008] As a preferred embodiment of the present invention, a first metal plate is fixedly placed in the first groove of the first engaging plate, and a magnet group in a bow shape composed of a plurality of magnets is fixedly installed on the top of the first metal plate.

[0009] As a preferred embodiment of the present invention, a heat insulation block for heat insulation is fixedly installed at each gap of the magnet group in a bow shape on the top of the first metal plate.

[0010] As a preferred embodiment of the present invention, a second groove adapted to the position and size of the first groove is formed at the bottom of the second engaging plate, and a second metal plate is clamped in the second groove at the bottom of the second engaging plate.

[0011] As a preferred embodiment of the present invention, four engaging rods are fixed on the bottom of the second engaging plate outside the second groove and are distributed in a rectangular array, and each engaging rod is respectively adapted to the position of one of the engaging blocks.

[0013] As a preferred embodiment of the present invention, inserting rods are inserted into the four circular holes of the second engaging plate, and a holding block is connected to one end of each inserting rod away from the center of the second engaging plate.

[0014] Technical effects and advantages of the hybrid energy storage system: During use, the electric energy generated by photosynthesis of the solar panel is directly transmitted to the energy storage battery for storage. During this process, the solar panel will generate heat under the direct sunlight effect, and the heat generated by the solar panel will be directly conducted to the second engaging plate and the second metal plate, making the temperature of the second engaging plate relatively high. At this time, under the action of several heat insulation blocks, the second engaging plate will not conduct heat to the first engaging plate and the first metal plate, resulting in a temperature difference between the second metal plate and the first metal plate. At this time, under the action of the magnet group, the second metal plate, the first metal plate and the magnet group form a thermoelectric generation loop, and thermoelectric generation can be carried out and stored in the energy storage battery. This process will consume the heat conducted to the second engaging plate, reduce the amount of heat conducted to the first engaging plate and the energy storage box after direct sunlight, reduce the influence degree of sunlight on the temperature of the energy storage box, prevent the temperature of the energy storage battery inside the energy storage box from being affected by sunlight, and can improve the service life of the energy storage battery.

[0015] After using for a period of time, if it is necessary to replace the second metal plate, pull out the four mating rods of the second engaging plate from the four mating blocks of the first engaging plate, and the top layer structure and the bottom layer structure can be separated. After that, if it is necessary to replace the second metal plate, remove the four insertion rods at the shielding block, and the second metal plate can be separated from the second groove of the second engaging plate, which is convenient for replacing the second metal plate. This structure can be replaced after the second metal plate is damaged, extending the service life of the hybrid energy storage system. Brief Description of the Drawings

[0022] Please refer to Figures 1 - 10 A hybrid energy storage system as shown, including an energy storage box 101, a bottom layer structure 20 located above the energy storage box 101, and a top layer structure 30. One side of the top of the energy storage box 101 is an inclined surface 102 for facilitating the inclination of the solar panel. A storage compartment 103 is provided on one side surface of the energy storage box 101 away from the inclined surface 102. Ventilation slots 104 for facilitating the flow of air are provided on both symmetric side surfaces of the energy storage box 101. Four legs 105 for supporting the energy storage box 101 are fixed at the bottom and are distributed in a rectangular array. A storage battery 111 matching the shape of the storage compartment 103 is installed in the storage compartment 103 of the energy storage box 101. A sealing plate 112 for protecting the storage battery 111 is installed at the storage compartment 103 of the energy storage box 101. The storage battery 111 is stored in the storage compartment 103 of the energy storage box 101 through the sealing plate 112. The solar panel is fixed on the top of the second engaging plate 301.

[0023] In order to dissipate heat through the method of thermoelectric power generation using the temperature difference semiconductor, as Figures 1 - 9As shown in the figure, the bottom structure 20 includes: four struts 201 distributed in a rectangular array on the inclined surface 102 of the energy storage box 101, and a first engaging plate 202 at the top of the four struts 201. The top structure 30 includes: a second engaging plate 301 at the top of the first engaging plate 202, and four shielding blocks 305 distributed in a rectangular array on the two symmetric side surfaces of the second engaging plate 301; A first groove 203 is provided at the center of the top of the first engaging plate 202. Four engaging blocks 204 distributed in a rectangular array are fixed on the two symmetric side walls of the first engaging plate 202. A first metal plate 211 is fixedly placed in the first groove 203 of the first engaging plate 202. A magnet group 212 in the shape of a bow formed by a plurality of magnets is fixedly installed on the top of the first metal plate 211. A positive metal sheet 213 is welded at one end of the magnet group 212, and a negative metal sheet 214 is welded at the other end. The top of the magnet is attached to the second metal plate 311, and the bottom is attached to the first metal plate 211. Heat insulation blocks 221 for heat insulation are fixedly installed at each gap of the magnet group 212 in the shape of a bow on the top of the first metal plate 211, which can prevent heat from being conducted to the first metal plate 211 to a certain extent. A second groove 302 adapted to the position and size of the first groove 203 is provided at the bottom of the second engaging plate 301. A second metal plate 311 is clamped in the second groove 302 at the bottom of the second engaging plate 301. Four engaging rods 303 distributed in a rectangular array are fixed outside the second groove 302 at the bottom of the second engaging plate 301. Each engaging rod 303 is respectively adapted to the position of one of the engaging blocks 204, so that the second engaging plate 301 can be clamped on the top of the first engaging plate 202.

[0024] To facilitate the replacement of the second metal plate 311, as Figures 8 - 10 shown, circular holes 304 are provided at each shielding block 305 on the second engaging plate 301. Insertion rods 321 are inserted into the four circular holes 304 of the second engaging plate 301. A holding block 322 is connected to one end of each insertion rod 321 away from the center of the second engaging plate 301. The holding block 322 is located inside the shielding block 305, which can shield the holding block 322 to prevent the insertion rod 321 from being pulled out when the second metal plate 311 does not need to be replaced.

[0025] After considering the advantages and disadvantages of existing energy storage systems, this hybrid energy storage system is selected to deal with the heat generated by solar panels under direct sunlight during the solar power generation process. After installation, the hybrid energy storage system is put into use in a photosynthetic power generation project. During use, the electric energy generated by the photosynthesis of the solar panels is directly transmitted to the energy storage battery 111 for storage. During this process, the solar panels will generate heat under direct sunlight, and the heat generated by the solar panels will be directly conducted to the second clamping plate 301 and the second metal plate 311, making the temperature of the second clamping plate 301 relatively high. At this time, under the action of several heat insulation blocks 221, the second clamping plate 301 will not conduct heat to the first clamping plate 202 and the first metal plate 211, resulting in a temperature difference between the second metal plate 311 and the first metal plate 211. At this time, under the action of the magnet group 212, the second metal plate 311, the first metal plate 211 and the magnet group 212 form a thermoelectric generation circuit, and thermoelectric generation can be carried out and stored in the energy storage battery 111. After using for a period of time, if the second metal plate 311 needs to be replaced, the four mating rods 303 of the second clamping plate 301 are pulled out from the four mating blocks 204 of the first clamping plate 202, and the top structure 30 and the bottom structure 20 can be separated. After that, if the second metal plate 311 needs to be replaced, the four insertion rods 321 at the shielding block 305 are removed, and the second metal plate 311 can be separated from the second groove 302 of the second clamping plate 301, which is convenient for replacing the second metal plate 311.
