Description

Technical Field

[0001] The present invention relates to the field of energy storage power stations, and in particular to an energy storage power generation device used in energy storage power stations. Background Art

[0002] New energy sources include solar energy, wind energy, biomass energy, hydropower and other biofuels derived from renewable energy. Compared with traditional energy sources, new energy sources have the advantages of less pollution and large reserves. Therefore, the development and utilization of new energy sources are bound to play a huge role in electric vehicles, smart grids, microgrids, distributed energy systems and future energy security. With the extensive application of new energy sources, its energy storage power stations have come into being.

[0003] The existing energy storage power station is divided into a power station body and a control box, which are arranged on both sides of the partition wall and do not interfere with each other during operation. The Chinese patent with the announcement number CN115863853A discloses an energy storage power station, wherein the power station body forms a battery compartment and a system equipment compartment, the wall of the battery compartment is provided with a first air inlet connected to the outside, the partition wall is provided with a first air outlet connected to the battery compartment and the system equipment compartment, and the wall of the system equipment compartment is provided with a second air outlet connected to the outside;

[0004] During actual use of the above structure, the battery packs in the energy storage power station are mostly stacked up and placed on the frame. When the heat is dissipated through the cooperation of the vents and the fan blades, a large amount of heat will accumulate on the contact surface between each battery pack. This heat is not easy to be discharged with the flow of air, resulting in poor overall heat dissipation effect. At the same time, in order to ensure the stability of the battery pack during operation, it is usually necessary to limit and fix the battery pack. When the staff perform subsequent maintenance, they need to be disassembled one by one, which increases the maintenance burden of the staff and reduces the overall maintenance efficiency. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an energy storage power generation device used in an energy storage power station to solve the technical problem that a large amount of heat will accumulate on the contact surface between each group of battery groups, resulting in poor overall heat dissipation effect. When subsequent staff perform maintenance, they need to disassemble them one by one, which increases the maintenance burden of the staff and reduces the overall maintenance efficiency.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an energy storage power generation device used in an energy storage power station, comprising a box body, wherein a control chamber and a battery pack chamber are respectively arranged in the box body, and an array of slide plates are slidably arranged in the battery pack chamber, and an array of support rods are hinged on the top of the slide plate, and a placement plate is hinged at the other end of the support rod, and a clamping plate cooperating with the support rod is symmetrically arranged on the placement plate;

[0007] A circulation component is arranged on the top of the box body, and a U-shaped tube is connected to the slide plate located at the output end of the circulation component, and a water storage chamber is formed between the slide plate at the bottom layer and the box body. A liquid discharge port is arranged in the water storage chamber, and a liquid inlet is arranged on the other side thereof. A liquid inlet pipe is connected to the liquid inlet, and the other end of the liquid inlet pipe is connected to the circulation component.

[0008] By adopting the above technical solution, the battery packs are placed one by one on the top of the placement plate, which improves the heat dissipation effect of the battery pack during subsequent work. Then, the placement plate is driven downward by the weight of the battery pack itself. At this time, the clamping plate will limit the two sides of the battery pack. In this process, the battery pack is automatically clamped, which effectively reduces the disassembly burden of subsequent staff. The coolant is drawn through the liquid inlet pipe and discharged into the U-shaped tube in the skateboard. In this process, the bottom of each battery pack is evenly dissipated, which further improves the overall heat dissipation effect.

[0009] The present invention is further configured such that the circulation component is a circulation pump, and the circulation pump is used to discharge the coolant drawn from the liquid inlet pipe into the U-shaped tube.

[0010] Preferably, under the action of a circulating pump, the cooling liquid in the water storage chamber can be discharged into the U-shaped tube, and in this process, the cooling liquid is ensured to circulate in the mechanism.

[0011] The present invention is further configured as follows: a floating plate is provided in the water storage chamber for sliding up and down, a plug rod is provided on the top of the floating plate, a limiting column is connected to the top of the plug rod, and the outer diameter of the limiting column is smaller than the outer diameter of the plug rod, sliding blocks are symmetrically provided on both sides of the slide plate, and a wedge-shaped groove for the plug rod to pass through is provided on the sliding block.

[0012] Preferably, the water source in the water storage chamber will drive the float plate to slide upwards. During this process, the insertion rod will drive the limiting column to be stuck in the wedge-shaped groove of the slider. At this time, the limiting of the slider is completed to prevent the subsequent slider from shaking in the box. When the water source in the subsequent water storage chamber is discharged, the float plate will slide downward. At this time, the insertion rod will drive the limiting column to move downward, thereby releasing the limiting of the wedge-shaped groove, making it convenient for the staff to directly slide the slider out, thereby further improving the maintenance efficiency of the battery pack on the slider.

[0013] The present invention is further configured such that a slot is provided on the top of the placement plate, and a clamping block is symmetrically slidably provided in the slot, and the bottom end of the clamping block is hinged to the support rod, wherein the clamping block can slide in the slot through the support rod.

[0014] Preferably, when the placement plate moves downward under the action of the battery pack, one end of the support rod will contract inward, causing the block in the slot to slide inward. During this process, the block will drive the clamping plate to slide inward to complete the clamping of the battery pack.

[0015] The present invention is further configured such that a limiting mechanism is provided on the outer wall of the block at the slot, and a rough surface is provided between the two.

[0016] Preferably, the limiting mechanism ensures the stability of the card block sliding in the slot, preventing the card block from falling off the slot, and the rough surface between the two further increases the sliding friction between the card block and the slot, preventing the card block from shifting in position under a slight impact.

[0017] The present invention is further configured such that the height of the liquid discharge port in the water storage chamber is lower than the height of the liquid inlet in the water storage chamber.

[0018] Preferably, during this process, when the liquid inlet draws the internal coolant, the float plate is always kept at a certain height, and at the same time, there is always water in the water storage chamber.

[0019] The present invention is further configured such that an array of through holes is provided on the outer wall of the box body at the slide plate, and heat dissipation components are rotatably arranged in the through holes.

[0020] Preferably, the heat in the battery pack cavity can be discharged outwardly through the action of the heat dissipation component, which effectively prevents the heat from accumulating in the battery pack cavity when the battery pack is working, and further improves the overall working environment of the battery pack.

[0021] The present invention is further configured such that the inner diameter of the opening at one end of the wedge-shaped groove is larger than the outer diameter of the insertion rod, and is smaller than the outer diameter of the limiting column.

[0022] Preferably, when the wedge groove of the slider moves to the insertion rod, the slider can slide out of the battery pack chamber directly through the slider. When the wedge groove moves to the limiting column, the slider can be limited, thereby preventing the subsequent slider from shaking in the box.

[0023] The present invention is further configured such that the inner walls of the splints are all provided with protective covers.

[0024] Preferably, the protective cover can prevent the inner wall of the clamping plate from directly contacting the battery pack, which further improves the protection effect of the battery pack and effectively prevents the battery pack from being worn during the clamping process.

[0025] The present invention is further configured such that the top of the placement plate is configured to be rough.

[0026] Preferably, the rough setting will result in a certain sliding friction between the battery pack and the placement plate, thereby preventing the battery pack from shifting on the top of the placement plate.

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] 1. The present invention provides an array of slide plates for sliding in the battery pack chamber, and places the battery packs one by one on the top of the placement plate. In this process, the battery packs are placed separately, which improves the heat dissipation effect of the battery pack in the subsequent working process. Then, the placement plate is driven downward by the action of the battery pack's own gravity. At this time, the clamping plate will limit the two sides of the battery pack. In this process, the battery pack is automatically clamped, which effectively reduces the disassembly burden of subsequent staff. The coolant is drawn into the U-shaped tube in the slide plate through the liquid inlet pipe and discharged. In this process, the bottom of each battery pack is evenly dissipated, which further improves the overall heat dissipation effect.

[0029] 2. The present invention has a floating plate slidingly arranged in the water storage chamber, and a plug rod is connected to the top of the floating plate. During the circulation of the coolant, the water source in the water storage chamber will drive the floating plate to slide upward. During this process, the plug rod will drive the limiting column to be stuck in the wedge-shaped groove of the slider. At this time, the limiting of the slide plate is completed to prevent the subsequent sliding plate from shaking in the box, further improving the overall working stability of the battery pack. When the water source in the water storage chamber is subsequently discharged, the floating plate will slide downward. At this time, the plug rod drives the limiting column to move downward, thereby releasing the limiting of the wedge-shaped groove, making it convenient for the staff to directly slide the slide plate out, thereby further improving the maintenance efficiency of the battery pack on the slide plate.

[0041] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] The following describes an embodiment of the present invention based on its overall structure.

[0043] First embodiment:

[0044] See also Figure 1-Figure 9 The energy storage power generation device used in the energy storage power station shown includes a box body 1, a control chamber 2, a battery pack chamber 3, a cooling mechanism, a circulation mechanism and a limiting mechanism. The power generation of the battery pack in the battery pack chamber 3 can be converted under the action of the control chamber 2. In addition, electricity is stored during the valley period of the power grid and fed back to the power grid during the peak period, which effectively reduces the peak and fills the valley, improves the stability of the power supply network, and reduces the overall electricity cost. An array slide plate 12 is slidably arranged in the battery pack chamber 3, wherein the top of the slide plate 12 is hinged with an array support rod 9, and the other end of the support rod 9 is hinged with a placement plate 7. Since the top of the placement plate 7 is arranged in a rough shape, there will be a certain sliding friction between the battery pack and the placement plate 7 to prevent the battery pack from being displaced on the top of the placement plate 7. When the staff places the battery pack on the top of the placement plate 7, the battery pack is placed separately in this process, which improves the heat dissipation effect of the battery pack in the subsequent working process.

[0045] At the same time, a clamping plate 8 cooperating with the support rod 9 is symmetrically arranged on the placement plate 7, a slot 14 is opened at the top of the placement plate 7, and a clamping block 15 is symmetrically slidably arranged in the slot 14, and the bottom end of the clamping block 15 is hinged to the support rod 9, wherein the clamping block 15 can slide in the slot 14 through the support rod 9. When the placement plate 7 moves downward under the gravity of the battery pack, one end of the support rod 9 will shrink inward, at this time causing the clamping block 15 in the slot 14 to slide inward, and in this process the clamping block 15 will drive the clamping plate 8 to slide inward together to complete the clamping of the battery pack, effectively reducing the disassembly burden of subsequent staff, and the inner wall of the clamping plate 8 is provided with a protective cover, which can prevent the inner wall of the clamping plate from directly contacting the battery pack, further improving the protection effect of the battery pack in this process, and effectively preventing the battery pack from being worn during the clamping process;

[0046] A circulation pump 4 is provided on the top of the housing 1, and a U-shaped tube 19 is connected to the skateboard 12 between the output end of the circulation pump 4 and the slide board 12. The coolant is pumped into the U-shaped tube 19 in the skateboard 12 by the action of the circulation pump 4. In this process, the U-shaped tube 19 realizes uniform heat dissipation of the bottom of each battery pack, further improving the overall heat dissipation effect, and a water storage chamber 11 is formed between the skateboard 12 at the bottom and the housing 1, a drain port 20 is provided in the water storage chamber 11, and a liquid inlet 13 is provided on the other side thereof, a liquid inlet pipe 5 is connected to the liquid inlet 13, and the other end of the liquid inlet pipe 5 is connected to the circulation pump 4, and the excess coolant will be discharged into the water storage chamber 11 through the drain port 20, and then the coolant will circulate through the cooperation of the liquid inlet pipe 5 and the liquid inlet 13, thereby reducing the overall cooling cost and improving the cooling efficiency of the battery pack.

[0047] In the above embodiments, please refer to Figure 5 A limiting mechanism is arranged on the outer wall of the block 15 at the slot 14, and a rough surface is arranged between the two. Under the action of the limiting mechanism, the stability of the block 15 sliding in the slot 14 is ensured to prevent the block 15 from falling off in the slot 14, and the rough surface between the two further improves the sliding friction between the block 15 and the slot 14 to prevent the block 15 from shifting in position under a slight impact.

[0048] In the above embodiments, please refer to Figure 2 and Figure 4 An array of through holes is provided on the outer wall of the box body 1 at the slide plate 12, and a heat dissipation component 6 is rotatably arranged in the through holes. The heat dissipation component 6 can discharge the heat in the battery pack chamber 3 to the outside, effectively preventing the heat from accumulating in the battery pack chamber 3 when the battery pack is working, and further improving the overall working environment of the battery pack.

[0049] Second embodiment:

[0050] See also Figure 2 , Figure 6 and Figure 8 The energy storage power generation device shown in the figure is used in an energy storage power station. The overall structure is similar to that of the first embodiment, wherein a floating plate 10 is provided in a water storage chamber 11 so as to slide up and down, a plug rod 21 is provided on the top of the floating plate 10, and a limiting column 17 is connected to the top of the plug rod 21, and the outer diameter of the limiting column 17 is smaller than the outer diameter of the plug rod 21, and sliders 16 are symmetrically provided on both sides of the slide plate 12, and a wedge-shaped groove 18 for the plug rod 21 to penetrate is provided on the slider 16, and the water source in the water storage chamber 11 will drive the floating plate 10 to slide upward, and in this process, the plug rod 21 will drive the limiting column 17 to be stuck. The wedge-shaped groove 18 is inserted into the wedge-shaped groove 18 of the slider. Since the inner diameter of the opening at one end of the wedge-shaped groove 18 is larger than the outer diameter of the insertion rod 21 and smaller than the outer diameter of the limiting column 17, when the wedge-shaped groove 18 of the slider 16 moves to the insertion rod 21, the slider 12 can slide directly out of the battery pack chamber 3 through the slider 16, which is convenient for subsequent staff to directly slide the slider out, thereby further improving the maintenance efficiency of the battery pack on the slider. When the wedge-shaped groove 18 is displaced to the limiting column 17, the slider 16 can be limited at this time, thereby preventing the subsequent slider 12 from shaking in the box body 1.

[0051] In the above embodiments, please refer to Figure 2 , and the height of the drain port 20 in the water storage chamber 11 is lower than the height of the liquid inlet 13 in the water storage chamber 11. In this process, when the liquid inlet 13 extracts the internal coolant, only the coolant at the liquid inlet 13 is extracted, and the coolant at the bottom of the liquid inlet 13 will not be extracted through the liquid inlet pipe 5. In this process, it is ensured that the floating plate 10 will always remain at the same height in the water storage chamber 11, and at the same time, there will always be part of the coolant in the water storage chamber 11, thereby completing the secondary utilization of the coolant itself, further reducing the overall cooling cost.

[0052] The present invention is used in specific operation: when in use, the battery packs are placed one by one on the top of the placement plate 7, so that each battery pack is placed separately. When the heat dissipation component 6 is used to dissipate heat from the battery pack, it is effectively prevented that the heat between the battery packs is difficult to discharge. At the same time, the placement plate 7 is driven downward by the gravity of the battery pack itself. At this time, the clamping plate 8 on the placement plate 7 slides inward, thereby completing the limited clamping work of the battery pack. In this process, the staff does not need to manually limit and fix it by the bolt assembly, which further improves the subsequent maintenance efficiency of the battery pack by the staff;

[0053] And during the working process, the circulation pump 4 on the top of the box body 1 is started, and the coolant is discharged into the U-shaped tube 19 in the slide plate 12 under the action of the circulation pump 4. At this time, the coolant flows in the U-shaped tube 19, which can take away part of the heat at the bottom of the battery pack, thereby further improving the overall heat dissipation effect, and the excess coolant will be discharged into the water storage chamber 11 through the drain port 20, and then the coolant is circulated through the cooperation of the liquid inlet pipe 5 and the liquid inlet port 13, thereby reducing the overall cooling cost and improving the cooling efficiency of the battery pack.

[0054] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
