Since the integrated machine needs to be inspected and repaired during use, and the PCS module and the junction box are fixedly connected and not convenient to disassemble for maintenance, it is necessary to reserve a certain amount of space between the two modules to facilitate maintenance. However, this will make the overall width of the energy storage and boosting integrated machine larger, and it cannot be installed in a standard container for transportation, which increases the production cost and transportation cost of the energy storage and boosting integrated machine.

[0030] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples.

In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0031] In the current modular design of energy storage, several PCS modules (power conversion systems, hereinafter referred to as PCS modules) and a junction box are usually processed and welded into a whole (hereinafter referred to as a module), and then the two modules are installed with a transformer mechanism to form an energy storage and boosting integrated machine. Since the integrated machine needs to be inspected and repaired during use, and the PCS modules and the junction box are fixedly connected and not convenient to disassemble for maintenance, it is necessary to reserve a certain amount of space between the two modules to facilitate maintenance by the staff. Therefore, the overall width of the energy storage and boosting integrated machine is large and cannot be installed in a standard container for transportation, which increases the production cost and transportation cost of the energy storage and boosting integrated machine. The utility model provides an energy storage and boosting integrated machine, which aims to reduce the space occupied by the PCS modules in the width direction of the energy storage and boosting integrated machine, so that the energy storage and boosting integrated machine can be installed in a standard container for transportation, reducing the production cost and transportation cost of the energy storage and boosting integrated machine.

[0032] See also Figures 1 to 3, an embodiment of the present invention provides an energy storage and boosting integrated machine, including a base 100, a box body 200, a PCS module, and a junction cabinet 400, the transformer mechanism 500 is arranged on the base 100, the box body 200 is arranged on the base 100, the box body 200 has a first mounting layer 210 and a second mounting layer 220 distributed up and down, in the length direction of the base 100, the first mounting layer 210 is provided with a plurality of mounting parts, in the width direction of the base 100, at least two groups of PCS modules are installed on the first mounting layer 210, and the length of the PCS module is arranged toward the length direction of the base 100, a PCS module includes a plurality of PCS modules 300, a PCS module 300 is correspondingly detachably connected to a mounting part, the junction cabinet 400 is detachably mounted on the second mounting layer 220, and the junction cabinet 400 is electrically connected to the plurality of PCS modules 300 and the transformer mechanism 500 respectively.

[0033] In this way, since the junction cabinet 400 can be removably installed on the second installation layer 220, and the PCS module 300 can be removably installed on the first installation layer 210, the PCS module 300 and the junction cabinet 400 are separated and independently installed on the upper and lower installation layers of the box body 200, which facilitates the separate disassembly and maintenance of the PCS module 300, and eliminates the need to reserve space between the two PCS modules for subsequent maintenance. This reduces the space occupied by the PCS module in the width direction of the base 100, reduces the width dimension of the energy storage and boosting integrated machine, and enables the energy storage and boosting integrated machine to be placed in a standard container 700 for transportation, thereby reducing the production cost and transportation cost of the energy storage and boosting integrated machine.

[0034] Optionally, in one embodiment, the mounting portion includes a plurality of mounting rails 211 and a plurality of base plates 212 provided on the first mounting layer 210. In the length direction of the base 100, the plurality of mounting rails 211 are provided on opposite sides of the top of the first mounting layer 210, and the plurality of base plates 212 are provided on opposite sides of the bottom of the first mounting layer 210. Two adjacent mounting rails 211 are provided corresponding to a base plate 212. The top of a PCS module 300 slides into and is installed on two adjacent mounting rails 211, and the bottom is correspondingly detachably connected to a base plate 212.

[0035] In this way, multiple mounting rails 211 are set at the top of the mounting part and multiple base plates 212 are set at the bottom. The top of the pcs module 300 is slid into and installed on the mounting rails 211, and the bottom is detachably installed on the base plate 212 to complete the installation of the pcs module 300 on the first mounting layer 210. The provision of the mounting rails 211 reduces the friction between the top of the pcs module 300 and the first mounting layer 210, making it difficult for the pcs module 300 to be damaged by friction with the first mounting layer 210, and improving the installation efficiency of the pcs module 300.

[0036] Optionally, in another embodiment, a plurality of mounting rails 211 may also be provided at the bottom of the first mounting layer 210 to further reduce the friction between the PCS module 300 and the first mounting layer 210 during installation, thereby improving the installation efficiency of the PCS module 300.

[0037] Optionally, in one embodiment, in the length direction of the base 100, the mounting portion further includes a plurality of first limiting members 213 and a plurality of second limiting members 214 arranged on opposite sides of the first mounting layer 210, a first limiting member 213 being arranged between two adjacent mounting rails 211 and abutting against the top of a corresponding pcs module 300, and a second limiting member 214 being arranged between two adjacent bottom plates 212 and abutting against the bottom of a corresponding pcs module 300.

[0038] In this way, multiple first limiting members 213 and second limiting members 214 are set on opposite sides of the first mounting layer 210 in the length direction. The first limiting members 213 abut against the top of the pcs module 300 to limit the displacement of the top of the pcs module 300 in the width direction of the first mounting layer 210, so that the top of the pcs module 300 is not easily moved in the width direction of the first mounting layer 210, which may cause the pcs module 300 to be skewed or tilted, thereby improving the installation stability of the pcs module 300. The second limiting members 214 abut against the bottom of the pcs module 300 to limit the displacement of the bottom of the pcs module 300 in the width direction of the first mounting layer 210, so that the bottom of the pcs module 300 is not easily moved in the width direction of the first mounting layer 210, which may cause the pcs module 300 to be unstable in installation, thereby improving the stability of the pcs module 300 in the first mounting layer 210.

[0039] Optionally, in another embodiment, there may be multiple ways to limit the displacement of the PCS module 300 in the width direction of the first mounting layer 210. A plurality of baffles may be provided on opposite sides of the first mounting layer 210 so that each PCS module 300 abuts against the baffle to limit the displacement of the PCS module 300 in the width direction of the first mounting layer 210.

[0040] Optionally, in one embodiment, the first mounting layer 210 is arranged above the second mounting layer 220, and the box body 200 also includes a plurality of vents 215 arranged on the periphery of the first mounting layer 210 for allowing gas to flow into the first mounting layer 210, and the box body 200 also includes a cover plate 230 arranged above the mounting rail 211, and the cover plate 230 has a plurality of vent holes 231 for allowing gas to flow out of the first mounting layer 210.

[0041] In this way, multiple ventilation parts 215 are set around the first mounting layer 210 to allow gas to enter the first mounting layer 210, so that the gas absorbs the heat of the PCS module 300 in the first mounting layer 210, and multiple ventilation holes 231 are set on the cover plate 230 to allow the gas that has absorbed the heat of the PCS module 300 to flow out of the first mounting layer 210, so as to bring the heat of the PCS module 300 out of the first mounting layer 210, ensure normal heat dissipation of the PCS module 300, and reduce the possibility of damage to the PCS module 300 due to poor heat dissipation.

[0042] Optionally, in another embodiment, there may be many ways to dissipate heat for the pcs module 300 , and a cooling fan may be installed in the first installation layer 210 to dissipate heat in the first installation layer 210 out of the first installation layer 210 .

[0043] Optionally, in one embodiment, a gap is provided between the cover plate 230 and the top of the pcs module 300 .

[0044] In this way, a gap is set between the cover plate 230 and the top of the pcs module 300 to reduce the possibility of debris blocking the top air outlet of the pcs module 300, thereby causing poor exhaust and reducing the heat dissipation of the pcs module 300. It can also reduce turbulence and resistance to ensure that the gas in the first mounting layer 210 can be discharged stably, thereby improving ventilation efficiency and the heat dissipation effect of the pcs module 300.

[0045] Optionally, in one embodiment, multiple vents 215 are arranged between the first mounting layer 210 and the second mounting layer 220, the vents 215 are connected to the first mounting layer 210 and the second mounting layer 220, and a gap is provided between the top of the junction cabinet 400 and the bottom of the pcs module 300.

[0046] In this way, the vent 215 connects the first mounting layer 210 and the second mounting layer 220, allowing gas to enter the first mounting layer 210 and the second mounting layer 220, increasing the air flow in the first mounting layer 210 and the second mounting layer 220, and improving the heat dissipation efficiency of the PCS module 300 and the junction cabinet 400. A gap is set between the top of the junction cabinet 400 and the bottom of the PCS module 300 to reduce the possibility that the junction cabinet 400 and the PCS module 300 are close to each other, resulting in poor gas circulation in the first mounting layer 210 and the second mounting layer 220, thereby reducing the heat dissipation effect of the junction cabinet 400 and the PCS module 300.

[0047] Optionally, in one embodiment, a gap is provided between the combiner cabinet 400 and the bottom of the second installation layer 220 , the base 100 is provided at the bottom of the second installation layer 220 , and the base 100 is provided with a plurality of through holes 110 .

[0048] In this way, a gap is provided between the combiner cabinet 400 and the bottom of the second mounting layer 220, and a plurality of through holes 110 are opened at the bottom of the second mounting layer 220 to increase the air flow entering the second mounting layer 220, thereby improving the heat dissipation effect in the combiner cabinet 400, and reducing the weight of the base 100, thereby reducing the production cost of the energy storage and boosting integrated machine.

[0049] Optionally, in another embodiment, the through hole 110 is not limited to being provided on the base 100 , but may also be provided on the side of the second mounting layer 220 , as long as normal heat dissipation of the combiner cabinet 400 is ensured.

[0050] Optionally, in one embodiment, openings 240 are formed on two opposite sides of the box body 200 in the length direction of the base 100 to expose the PCS module and the combiner cabinet 400 .

[0051] In this way, openings 240 are opened on opposite sides of the box body 200 to expose the PCS module and the junction cabinet 400, increase the air flow entering the first installation layer 210 and the second installation layer 220, so as to improve the heat dissipation effect of the junction cabinet 400 and the PCS module, and reduce the weight of the box body 200, thereby reducing the production cost of the energy storage and boosting integrated machine.

[0052] Optionally, in one embodiment, the box body 200 and the transformer mechanism 500 are both provided with a hoisting portion 600 for connection with a hoisting device 800 for hoisting the energy storage and boosting integrated machine.

[0053] In this way, a hoisting part 600 is provided on the box body 200 and the transformer mechanism 500, so as to facilitate hoisting the box body 200 and the transformer mechanism 500 on the base 100 to complete the assembly of the energy storage and boosting integrated machine.
