They can also be used in areas with relatively low temperatures. The batteries can be used in series and in parallel to maintain consistency. They have good charging acceptance. In an unstable charging environment, they have strong charging acceptance.
[0004] The following shortcomings were found during subsequent use:
[0005] 1. The battery pack can only be simply fixed by the structure inside the shell. Long-term use will cause wear and tear of the internal structure of the shell, which will lead to the movement of the battery pack, posing a risk.
[0006] 2. The sealing between the outer shell and the end cover depends on the effect of sealant. The sealant is easy to fall off from the joint during sealing. In order to achieve the sealing effect, the battery needs to be tilted. During the process, the electrolyte may spill and cause danger.
[0007] Therefore, in view of this, the existing structure is studied and improved, and an energy storage battery is proposed. Utility Model Content

[0031] As the instruction manual Figure 1 , 2As shown in Figure 3, an energy storage battery includes a shell 1, an end cover 2, a battery assembly 3, and an electrolyte. The end cover 2 is fixedly arranged on the top of the shell 1 by a sealant. A sealing assembly 6 is fixedly arranged between the shell 1 and the end cover 2. The sealing assembly 6 includes a solid frame 6.1 and a guide frame 6.2 fixedly arranged at the top of the shell 1. The solid frame 6.1 maintains the shape of the top of the shell 1, and the inclined part of the guide frame 6.2 can guide the sealant into the contact part between the shell 1 and the end cover 2, so as to assist the sealing of the shell 1 and the end cover 2.
[0032] As the instruction manual Figure 1 , 2 As shown in , 4, and 5, the battery assembly 3 and the electrolyte are arranged in the housing 1. The battery assembly 3 includes a plurality of battery packs 3.1 arranged inside the housing 1. A connecting strip 3.2 is movably buckled between the tops of two adjacent battery packs 3.1. A pair of brackets 4 are arranged on both sides of the battery pack 3.1. A connecting assembly 5 is slidably arranged between the two sides of the pair of brackets 4. The connecting assembly 5 adjusts and fixes the position of the pair of brackets 4 in the housing 1. The two adjacent brackets 4 are connected by the same connecting assembly 5. A handle is fixedly arranged at the top of the bracket 4, and the handle is used to facilitate the movement of the bracket 4. A plurality of filter screens are fixedly arranged near the bottom of the housing 1. The bracket 4 is movably placed above the filter screen. The waste residue generated by the battery pack 3.1 will be deposited on the filter screen to prevent a large amount of waste residue from accumulating on the battery pack 3.1 and causing a battery short circuit.
[0033] As the instruction manual Figure 1 , 2 As shown, the connecting component 5 is movably arranged between a pair of brackets 4, and the connecting component 5 includes a station column 5.1 slidably arranged on one side of the bracket 4, and an adjusting shaft 5.2 is threadedly rotatably arranged between the station columns 5.1 corresponding to a pair of brackets 4 of each battery pack 3.1, and the adjusting shaft 5.2 adjusts the position between the corresponding station columns 5.1, and a first T-shaped slider is fixedly arranged on one side of the bracket 4 close to the station column 5.1, and a first T-shaped groove cooperating with the sliding of the first T-shaped slider is arranged on the station column 5.1, and the bracket 4 slides vertically on the station column 5.1, and the cooperation between the first T-shaped slider and the first T-shaped groove facilitates the bracket 4 to be removed from and put back on the station column 5.1.
[0034] As the instruction manual Figure 1 , 2As shown, the adjustment shaft 5.2 is rotatably arranged between the two sides of the housing 1, and the adjustment shaft 5.2 includes a rotating shaft 5.3 rotatably arranged between the two sides of the housing 1, and a knob 5.4 fixedly arranged in the middle of the rotating shaft 5.3. The rotating shaft 5.3 is connected to the housing 1 through a bearing, and a positive thread and a negative thread are fixedly arranged on the rotating shaft 5.3, and the positive thread and the negative thread on both sides of the knob 5.4 have opposite rotation directions. A positive thread hole for the positive thread to rotate is arranged on one of the corresponding station columns 5.1, and a negative thread hole for the negative thread to rotate is arranged on the other corresponding station column 5.1. The adjustment shaft 5.2 is located between the two corresponding station columns 5.1, and passes through the station columns 5.1 at both ends through the rotating shaft 5.3 thread rotation. A second T-shaped slider is fixedly provided at the bottom of the station column 5.1, and a second T-shaped groove cooperating with the second T-shaped slider is fixedly provided at the bottom of the shell 1. The cooperation between the second T-shaped slider and the second T-shaped groove facilitates the sliding of the station column 5.1 on the shell 1. Since the positive thread is rotatably connected with the positive thread hole, and the negative thread is rotatably connected with the negative thread hole, the positions of the station columns 5.1 on both sides can be adjusted simultaneously by turning the knob 5.4.
[0035] The working principle of the utility model is as follows: a plurality of filter screens are fixed by screws at the bottom of the inner shell 1, and the filter screens can fix the residue in the electrolyte to prevent the residue from accumulating in large quantities on the battery pack 3.1 and causing a short circuit. The battery pack 3.1 is placed between a pair of brackets 4, and the knob 5.4 located inside the shell 1 is turned, and the knob 5.4 drives the shaft 5.3 to rotate. Since the thread of the shaft 5.3 rotates through the corresponding two station posts 5.1, and the threads on the shaft 5.3 on both sides of the knob 5.4 rotate in opposite directions, the rotation of the knob 5.4 will simultaneously drive the two station posts 5.1 to move in the opposite or opposite directions, adjust the distance between the two station posts 5.1, and adjust another adjacent knob 5.4, so that each bracket 4 can be slidably connected with the two station posts 5.1 through the first T-shaped slide groove, and the position of a pair of brackets 4 is fixed by four station posts 5.1, and the position of the battery pack 3.1 between the pair of brackets 4 is fixed by fixing the position of the bracket 4. Repeat the above steps to put all the battery packs 3.1 into the shell 1, and connect the adjacent battery packs 3.1 through the connecting strip 3.2.
[0036] Since both the shell 1 and the end cover 2 are made of plastic materials, deformation may occur. The shape of the top of the shell 1 can be maintained by fixing the solid frame 6.1 at the top of the shell 1. The end cover 2 can also be sleeved on the top of the shell 1 through the solid frame 6.1. The end cover 2 is fixedly set between the solid frame 6.1 and the guide frame 6.2.
[0037] Pour the sealant into the guide frame 6.2, and the sealant will flow along the guide frame 6.2 into the joint between the housing 1 and the end cover 2. Then use a tool to smooth the sealant to complete the sealing of one side of the housing 1. Repeat the above steps to complete the sealing of the surrounding of the housing 1. Pour the electrolyte through the opening on the end cover 2, and check the height of the electrolyte through the observation hole until the battery pack 3.1 is completely immersed.
[0038] If part of the battery pack 3.1 is to be replaced, it is only necessary to cut the sealant between the housing 1 and the end cover 2 along the guide frame 6.2 to remove the end cover 2, and then it is only necessary to remove the corresponding connecting strip 3.2, and then lift the battery pack 3.1 through the handles above the pair of brackets 4 to prevent the human body from contacting the electrolyte.
[0039] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
