Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery storage, and particularly relates to a storage device for lithium batteries. Background Technique

[0002] A lithium battery is a type of battery with a lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been applied for a long time. With the development of science and technology, lithium batteries have now become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries.

[0003] When lithium batteries are used intensively, a bracket-like structure is generally set for centralized storage of lithium batteries. However, the existing devices cannot fix the storage device during storage. Once a collision occurs, the lithium batteries will collide with the storage device, which is very likely to cause danger. Moreover, lithium batteries have high requirements for temperature and humidity during storage, but the existing device has a poor storage environment and cannot meet the better protection of lithium batteries. If lithium batteries are not reasonably protected, it will cause the energy efficiency of lithium batteries to decrease and the service life to become shorter. For this reason, we provide a storage device for lithium batteries to solve the above problems. Summary of the Invention

[0004] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0005] The utility model provides a storage device for lithium batteries, which includes a plurality of combined and assembled lithium battery storage racks; the lithium battery storage rack includes columns, a lower cross beam connected between the lower parts of the columns, support beams equidistantly fixed on the upper side of the lower cross beam, ear seats fixed on the outer side of the outermost support beam, a limit beam connected to the ear seats through screws, and an upper cross beam connected between the upper parts of the columns;

[0006] A baffle is fixed on the outer side of the upper cross beam, and a temperature control component is arranged inside the baffle. The temperature control component includes a box body fixed on the inner side of the baffle, a heating grid attached to the inner side wall of the box body, a shaft rod movably arranged in the middle position of the box body, wind plates fixed on the side of the shaft rod, and a motor fixed to the shaft rod.

[0007] The utility model is further arranged such that a lithium battery body is arranged on the upper side of the support beam, and connection terminals are arranged at the corners of the upper side of the lithium battery body.

[0008] The utility model is further arranged such that a protective pad is fixed on the lower side of the limit beam, and the protective pad is clamped between the lower side of the limit beam and the upper side of the lithium battery body.

[0009] The present utility model is further configured such that a nut is connected to the end of the screw rod, and the structure of the nut abuts against the limiting beam and the ear seat.

[0010] The present utility model is further configured such that the upper and lower sides of the box body are both grid-shaped, and the box body is located between the vertically stratified lithium battery storage racks.

[0011] The present utility model is further configured such that the heating net is internally provided with a heating rod structure, and the heating rod is connected in parallel with the motor to an external control terminal.

[0012] The present utility model is further configured such that the heating net is a hollowed-out structure, and the heating net is matched with the grid surface of the box body.

[0013] The present utility model is further configured such that a bearing seat is embedded and installed at the middle position of the side surface of the box body, the bearing seat is matched with the end of the shaft rod, and the motor connected to one end of the shaft rod is fixed at the middle of one end of the box body.

[0014] The present utility model has the following beneficial effects:

[0015] 1. The present utility model centrally stores and uses a number of lithium battery bodies through the setting of the lithium battery storage racks. In the lithium battery storage racks, the support beam and the limiting beam are connected by the screw rod to realize the assembly and limitation of the lithium battery bodies. The number of combinations and the combination direction of a number of lithium battery storage racks are determined according to the actual storage requirements of the lithium battery bodies.

[0016] 2. The present utility model is provided with a temperature control component to assist in the heating or cooling of the lithium battery body to ensure the stable operation of the lithium battery body in different environments. The airflow generated by the rotation of the air plate driven by the motor and the shaft rod passes through the heating net and the grid surface of the side surface of the box body to increase the surface flow rate of the lithium battery body to realize the cooling of the lithium battery body. When heating is used, the rotation speed of the air plate is slower to ensure a relatively high degree of air heating.

[0017] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. Description of the Drawings

Specific embodiments

[0026] Please refer to Figure 1 and Figure 2 , the present utility model is a storage device for lithium batteries, including a plurality of assembled lithium battery storage racks; the lithium battery storage rack includes a support pillar 1, a lower cross beam 2 connected between the lower parts of the support pillars 1, support beams 5 equidistantly fixed on the upper side of the lower cross beam 2, ear seats 6 fixed on the outer side of the outermost support beam 5, a limit beam 8 connected to the ear seats 6 through a screw 7, and an upper cross beam 9 connected between the upper parts of the support pillars 1.

[0027] Specifically, in the storage device for lithium batteries involved in the present application, through the setting of the lithium battery storage rack for centralized storage and use of a plurality of the lithium battery bodies 4, in the lithium battery storage rack, the support beam 5 and the limit beam 8 are connected by the screw 7 to realize the assembly and limitation of the lithium battery body 4. The number of combinations and the combination direction of a plurality of the lithium battery storage racks are determined according to the actual storage requirements of the lithium battery body 4.

[0028] Furthermore, the lithium battery body 4 is arranged on the upper side of the support beam 5, and terminals 10 are arranged at the corners on the upper side of the lithium battery body 4; a protective pad is fixed on the lower side of the limit beam 8, and the protective pad is clamped between the lower side of the limit beam 8 and the upper side of the lithium battery body 4; a nut is connected to the end of the screw 7, and the structure of the nut abuts against the limit beam 8 and the ear seat 6. Specific Embodiment

[0029] Please refer to Figure 3 and Figure 4 Based on Specific Embodiment 1, a baffle 3 is fixed to the outer side of the upper crossbeam 9, and a temperature control component is arranged inside the baffle 3. The temperature control component includes a box body 11 fixed to the inner side of the baffle 3, a heating mesh 14 attached to the inner side wall of the box body 11, a shaft rod 12 movably arranged at the middle position of the box body 11, a wind plate 13 fixed to the side of the shaft rod 12, and a motor 15 fixed to the shaft rod 12.

[0030] Specifically, the temperature control component involved in the present application is used to assist in the heating or heat dissipation of the lithium battery body 4 to ensure the stable operation of the lithium battery body 4 in different environments. The airflow generated by the rotation of the wind plate 13 driven by the motor 15 and the shaft rod 12 passes through the heating mesh 14 and the grille surface on the side of the box body 11, increasing the surface flow rate of the lithium battery body 4 to achieve the cooling of the lithium battery body 4. When used for heating, the rotation speed of the wind plate 13 is slower to ensure a relatively high degree of air heating.

[0031] Furthermore, the upper and lower sides of the box body 11 are both grille-shaped, and the box body 11 is located between the vertically stratified lithium battery storage racks; the heating mesh 14 is internally provided with a heating rod structure, and the heating rod is connected in parallel with the motor 15 to an external control terminal; the heating mesh 14 is a hollow structure, and the heating mesh 14 cooperates with the grille surface of the box body 11; a bearing seat is embedded and installed at the middle position on the side of the box body 11, and the bearing seat cooperates with the end of the shaft rod 12, and the motor 15 connected to one end of the shaft rod 12 is fixed to the middle of one end of the box body 11.

[0032] Specifically, the upper and lower grilles of the box body 11 are used to ensure the air circulation inside and outside the box body 11. When the motor 15 is started, the output shaft of the motor 15 drives the shaft rod 12 to rotate, and the wind plate 13 relatively fixed to the shaft rod 12 rotates synchronously. During the rotation of the wind plate 13, the internal gas flow of the box body 11 is accelerated to form an air current, which is blown out from the grille surface to assist in the heat dissipation of several lithium battery bodies 4;

[0033] In a cold environment, to ensure the normal operation of the lithium battery body 4, it is necessary to perform a heating treatment on it. The heating rod built into the heating mesh 14 is powered on to heat the passing air. After the heated hot air contacts the surface of the lithium battery body 4, the heating treatment of the lithium battery body 4 is realized, ensuring that the lithium battery body 4 can operate normally in a cold environment.
