Description

TECHNICAL FIELD

[0001] The utility model relates to battery energy storage technology field, concretely is a kind of battery energy storage device. BACKGROUND

[0002] Battery energy storage device is a kind of device for storing electric energy, it can be converted into chemical energy by chemical reaction and stored, when needed, the stored chemical energy is converted into electric energy again by the reverse reaction process.

[0003] Due to the large number of batteries required in the battery energy storage device, and a lot of heat will be generated when working, the existing battery energy storage device mostly adopts the cabinet structure without cabinet door, such as the text with the name of a kind of battery energy storage device of Chinese patent announcement No. CN207852769U, mainly includes cabinet, the battery storage rack arranged in the cabinet and the energy storage battery placed on the battery storage rack. The cabinet structure without cabinet door not only improves the heat dissipation effect of energy storage battery, but also reduces the interference of cabinet door design on the taking and placing of a large number of energy storage batteries. But in actual application, the structure without cabinet door is still difficult to form air convection in the self-heat dissipation state, and the heat dissipation effect is limited. In addition, due to the design structure without cabinet door, the fixing effect of the cabinet on the energy storage battery is also reduced, and there is a risk of falling of the energy storage battery when the cabinet is shaken by collision, so it is urgent to solve. UTILITY MODEL CONTENT

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a kind of battery energy storage device, on the basis of guaranteeing the heat dissipation effect of energy storage battery, the stability of the fixed energy storage battery is ensured.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A kind of battery energy storage device, including cabinet, the inside of cabinet has the storage cavity for storing energy storage battery and is through from front to back, the side of the opening at the front and back of the storage cavity is provided with fender, two fenders are connected with the rotary shaft that is formed with the rotary cooperation of cabinet, the rotary shaft is arranged in parallel with the through direction of storage cavity, and the rotary shaft has the stop state of fender in the opening of storage cavity during rotation, and the opening state of fender deviating from the opening of storage cavity. The combination structure of storage cavity and fender improves the fixed stability of energy storage battery on the basis of guaranteeing the convenience of energy storage battery installation and disassembly, and also improves the natural heat dissipation effect of energy storage battery when working.

[0007] As a further aspect of this invention: from a forward-viewing angle along the through-direction of the storage cavity, the storage cavities are arranged in a matrix of several groups. A rotating shaft is installed in the middle of the cavity wall between adjacent horizontal or vertical rows of storage cavities. The rotating shaft is fixed to the middle of a stop bar, so that during rotation, the two ends of the stop bar can respectively form the stop state with the adjacent horizontal or vertical rows of storage cavities. When there are a large number of storage cavities, it is not necessary to open each storage cavity sequentially, further improving the convenience of installing and removing the energy storage battery.

[0008] As a further improvement of this utility model: the rotating shafts are distributed in the middle of the cavity walls between adjacent longitudinal storage chambers. The cabinet is also equipped with a power assembly that drives all rotating shafts to rotate synchronously. The power assembly includes a lifting frame capable of lifting and lowering. Rotating shafts located on the same vertical line form a longitudinal group. Vertically arranged adjusting plates are fixed to the frame adjacent to each longitudinal group on the lifting frame. Gears are coaxially fixed on the rotating shafts, and racks that mesh with all gears in the corresponding longitudinal group are provided on the adjusting plates. By driving all rotating shafts to rotate synchronously through the power assembly, the convenience of installing and removing energy storage batteries is further improved.

[0009] As a further improvement of this utility model, the power assembly also includes a lifting cylinder that drives the lifting frame to perform lifting movements, which has the advantage of fast power response.

[0010] As a further improvement of this utility model, a through hole is provided between adjacent storage cavities to connect them, which further increases the convection effect between the two open ends of the storage cavity.

[0011] As a further improvement of this utility model, the cabinet is also equipped with a cooling fan, and all storage cavities located on the left and right sides of the cabinet are connected to the exhaust end of the cooling fan through air outlet pipes. By blowing air through the cooling fan, the storage cavities on both sides can be cooled. Combined with the arrangement of the aforementioned through holes, even if the cabinet has more than two sets of longitudinally arranged storage cavities, the storage cavity in the middle can still be guaranteed to have a good heat dissipation effect. Thus, on the basis of improving the natural heat dissipation effect of the energy storage battery, the cooling fan's auxiliary heat dissipation effect on the energy storage battery is further improved.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The storage chamber of this utility model adopts a through-type structure, which allows convection between the front and rear sides of the storage chamber, further improving the heat dissipation efficiency of the energy storage battery in the storage chamber under natural heat dissipation conditions. Compared with the traditional storage chamber with one open end, this greatly improves the heat dissipation efficiency of the energy storage battery. Furthermore, when there are a large number of energy storage batteries and storage chambers, workers can load or unload batteries from the front and rear sides of the cabinet respectively, greatly improving the efficiency of loading and unloading energy storage batteries. In addition, a stop bar fixed to the same rotating shaft is provided at both open ends of the storage chamber. During the installation and loading of energy storage batteries, installation can be completed at either open end of the storage chamber, and the two open ends of the storage chamber can be sealed by rotating the stop bar on that side. Similarly, during the disassembly and unloading of energy storage batteries, the stop bar can be switched to the open state by rotating it at either open end of the storage chamber, after which the energy storage battery can be disassembled and unloaded. In summary, the combination of the storage cavity and the baffle in this utility model not only ensures the ease of installation and disassembly of the energy storage battery, but also improves the stability of the energy storage battery and enhances the natural heat dissipation effect of the energy storage battery during operation.

[0014] 2. The two baffles and the rotating shaft fixed between the two baffles can realize the synchronous opening or stopping of the opening ends of two adjacent storage chambers. When there are many storage chambers, it is not necessary to open each storage chamber in sequence, which can further improve the convenience of energy storage battery installation and removal.

[0015] 3. This utility model also includes a power assembly on the cabinet that drives all rotating shafts to rotate synchronously, further improving the convenience of installing and removing the energy storage battery. Furthermore, the power assembly uses a rack and pinion mechanism on the adjustment plate to drive the lifting motion of the lifting frame, occupying almost no additional horizontal space and not affecting the horizontal space occupied by the original battery energy storage device. Moreover, the rack and pinion mechanism driving all rotating shafts to rotate synchronously also has the advantages of stable power transmission and labor-saving operation.

[0016] 4. The lifting frame is driven by a lifting cylinder, which has the advantage of fast power response.

[0017] 5. Through holes are provided between adjacent storage chambers to allow them to communicate with each other, further increasing the convection effect between the two open ends of the storage chambers.

[0018] 6. This utility model is also equipped with a cooling fan. By blowing air through the cooling fan, the storage cavities on both sides can be cooled. Combined with the arrangement of the above-mentioned through holes, even if the cabinet has more than two sets of longitudinal storage cavities, the storage cavity in the middle can still have a good heat dissipation effect. Thus, on the basis of improving the natural heat dissipation effect of the energy storage battery, the cooling fan further enhances the heat dissipation effect of the energy storage battery.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0025] The specific structure of this utility model is as follows: Figures 1-3As shown, its main structure includes a cabinet 10 and storage cavities for storing energy storage batteries 20, which are disposed on the cabinet 10. The storage cavities have a through-type structure, allowing the energy storage batteries 20 to be loaded or unloaded from both the front and rear sides of the cabinet 10. When a large number of energy storage batteries 20 and storage cavities are needed, workers can load or unload the batteries from both the front and rear sides of the cabinet 10, greatly improving the efficiency of loading and unloading the energy storage batteries 20. Furthermore, the through-type structure of the storage cavities allows for convection between the front and rear sides, further improving the heat dissipation efficiency of the energy storage batteries 20 under natural heat dissipation conditions. Compared to traditional storage cavities with one open end, this significantly improves the heat dissipation efficiency of the energy storage batteries 20. However, since both the front and rear ends of the storage cavities are open, while improving heat dissipation efficiency, it undoubtedly increases the risk of the energy storage batteries 20 falling out. Therefore, in this application, baffles 32 are provided on the sides of the openings at both the front and rear ends of the storage cavities. Specifically, a rotating shaft 31, which forms a rotational engagement with the cabinet 10, connects the two baffles 32. This rotating shaft 31 is arranged parallel to the through direction of the storage cavity, and during rotation, it has a stop state where the baffles 32 are positioned at the opening of the storage cavity, and an open state where the baffles 32 are deviated from the opening. Specifically, in the stop state, the baffles 32 are positioned at the opening of the storage cavity, preventing the energy storage battery 20 from leaving the storage cavity. In practical implementation, high-strength materials are preferred, so that the size of the baffles 32 can be as small as possible while still satisfying the function of preventing the energy storage battery 20 from leaving, thus reducing the impact on airflow at the opening of the storage cavity. Furthermore, since both baffles 32 at the two opening ends are fixed to the same rotating shaft 31, during the installation and loading of the energy storage battery 20, installation and loading can be completed at any opening end of the storage cavity, and the two opening ends of the storage cavity can be sealed by rotating the baffle 32 on that side. Similarly, during the disassembly and unloading of the energy storage battery 20, the baffle 32 can be switched to the open state by rotating it at any opening end of the storage cavity, after which the energy storage battery 20 can be disassembled and unloaded. Thus, while ensuring the convenience of installation and disassembly of the energy storage battery 20, the fixed stability of the energy storage battery 20 is improved, and the natural heat dissipation effect of the energy storage battery 20 during operation is also improved.

[0026] Based on the above, such as Figure 1 and Figure 3As shown, from a frontal view along the direction of the storage cavity, the storage cavities are arranged in several groups in a dot matrix pattern. A rotating shaft 31 is installed in the middle of the cavity wall between adjacent horizontal or vertical rows of storage cavities. The rotating shaft 31 is fixed to the middle of a baffle 32, forming an I-shaped structure between the two baffles 32 and the rotating shaft 31. This ensures that during rotation, the two ends of the baffles 32 can respectively stop the rotation of the rotating shaft 31 with the adjacent horizontal or vertical rows of storage cavities. In this embodiment, the two baffles 32 and the rotating shaft 31 fixed between them can simultaneously open or stop the openings of two adjacent storage cavities. When there are many storage cavities, it is not necessary to open each storage cavity sequentially, further improving the convenience of installing and removing the energy storage battery 20.

[0027] Based on the above, such as Figure 1 and Figure 2 As shown, to further improve the ease of installation and removal of the energy storage battery 20, in this embodiment, a power assembly 40 is also provided on the cabinet 10 to drive all rotating shafts 31 to rotate synchronously. Specifically, the rotating shafts 31 are distributed in the middle of the cavity walls between adjacent longitudinal storage chambers; the power assembly 40 includes a lifting frame 41 capable of lifting and lowering, with the rotating shafts 31 located on the same vertical line forming a longitudinal group. Vertically arranged adjustment plates 42 are fixed on the frame of the lifting frame 41 adjacent to each longitudinal group. Gears 321 are coaxially fixed on the rotating shafts 31, and racks 421 are provided on the adjustment plates 42 that mesh with all gears 321 in the corresponding longitudinal group. In this embodiment, the lifting and lowering motion of the lifting frame 41 drives the racks 421 on the adjustment plates 42 to mesh with the gears 321, which occupies almost no additional horizontal space and does not affect the horizontal space occupied by the original battery energy storage device. In addition, the use of rack 421 and gear 321 to drive all rotating shafts 31 to rotate synchronously has the advantages of stable power transmission and labor saving.

[0028] Furthermore, such as Figure 1 As shown, the power assembly 40 also includes a lifting cylinder 43 that drives the lifting frame 41 to move up and down. It has a fast power response. In actual implementation, the transmission stroke of the lifting cylinder 43 is selected according to requirements so that when the lifting cylinder 43 rises or falls to its limit position, the stop bar 32 is in the stopped or open state. Of course, in actual implementation, the lifting cylinder 43 is only one power source for driving the lifting frame 41 to move up and down. It can also be driven by a screw-slider mechanism, an electric cylinder, or a hydraulic cylinder; even, to reduce costs, the lifting cylinder 43 can be omitted, and the lifting frame 41 can be operated manually.

[0029] Based on the above, such as Figure 1As shown, through holes 11 are provided between adjacent storage cavities to allow them to communicate with each other, further increasing the convection effect between the two open ends of the storage cavities.

[0030] In addition, such as Figure 3 As shown, in actual implementation, a cooling fan 50 can also be installed on the cabinet 10. All storage cavities located on the left and right sides of the cabinet 10 are connected to the exhaust end of the cooling fan 50 through the air outlet pipe 51. By blowing air through the cooling fan 50, the storage cavities on both sides can be cooled. Combined with the arrangement of the through holes 11, even if the cabinet 10 has more than two sets of longitudinal storage cavities, the storage cavity in the middle can still have a good local cooling effect. Thus, on the basis of improving the natural cooling effect of the energy storage battery 20, the cooling fan 50 further enhances the auxiliary cooling effect of the energy storage battery 20.

[0031] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
