Description

Technical Field

[0001] The utility model relates to the technical field of energy storage batteries, in particular to a horizontal tube type energy storage battery. Background Art

[0002] At present, energy storage power stations that generally use batteries as energy storage media generally install several single battery units on a battery rack. In order to save site space, energy storage power stations of a certain scale also need to stack the entire battery rack and the batteries on it as an energy storage unit. The product characteristics of tubular lead-acid batteries are that they can withstand large current impacts and are suitable for high current discharge occasions. They have long charge and discharge cycle life, low self-discharge, high discharge depth, and long service life. However, they are large in size and weight, inconvenient to carry, have a high natural discharge rate, and are easily damaged if not charged for a long time. However, they are very suitable for the application scenarios of battery energy storage power stations.

[0003] However, the battery shell of the existing tubular lead-acid battery is generally in the shape of a long rectangular column. After being installed on the battery rack and stacked in multiple layers, the entire energy storage battery assembly will be high. Maintenance aisles need to be reserved on both sides of the battery assembly, wasting space that could have accommodated more batteries. When installing and maintaining the upper battery, personnel need to reach the top of the uppermost battery to access the upper battery pole, which is extremely inconvenient and unsafe for wiring or other operations. At the same time, the existing long box-type battery has a small size of a single pole plate, resulting in a low energy density. Therefore, the best way should be to lay the long columnar large pole plate tubular battery horizontally, which can effectively save space, is convenient for personnel to operate and wire, and has a high space utilization rate.

[0004] However, when the tubular lead-acid battery is charged and discharged, heat is generated inside the battery, and the electrolyte in the battery expands due to the heat during the charging and discharging process, and exhaust is required. The exhaust safety valve of the existing tubular lead-acid battery is generally arranged on the acid injection hole at the center of the upper cover on the top of the battery. After the battery is filled with acid, the exhaust safety valve cover is used to complete the sealing. If the battery is placed horizontally after acid injection, the battery liquid flowing in the battery will block the exhaust safety valve, causing safety problems. Summary of the invention

[0005] The utility model provides a tubular energy storage battery suitable for horizontal placement, which can effectively improve the space utilization rate of the energy storage power station, increase the energy storage capacity of the energy storage power station, and is convenient for maintenance and installation personnel to operate, avoiding safety problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A horizontal tubular energy storage battery, characterized in that it comprises a battery shell, a battery cover, and an exhaust safety valve; the battery shell is in the shape of a long column with a square cross section, one end of which is provided with the battery cover, and the battery cover is provided with pole holes symmetrical to the midline of the upper surface of the battery cover for the positive and negative poles to pass through;

[0008] Its characteristic is that one side of the two pole holes of the battery cover is also provided with an acid injection hole A. When the battery is placed horizontally, the lowest point of the lower edge of the acid injection hole is higher than the highest point of the liquid level in the battery when the battery is placed horizontally, and the exhaust safety valve is arranged in the acid injection hole.

[0009] A further solution is that an acid injection hole B symmetrical to the acid injection hole A is also provided on the other side of the two pole holes of the battery cover to increase the acid injection speed. When placed horizontally, only the exhaust safety valve of any one of the two acid injection holes can be opened to meet the exhaust requirements.

[0010] The beneficial effect of the utility model is that the acid injection hole set in the center of the battery cover in the prior art is set on one side of the two pole holes, so that the requirement of placing the tubular lead-acid battery horizontally can be met in the energy storage battery assembly, and the exhaust safety valve on the acid injection hole will not be blocked, which can effectively improve the space utilization rate of the energy storage power station, increase the energy storage capacity of the energy storage power station, facilitate maintenance and installation personnel to operate, avoid safety problems at the same time, and is simple to transform and has low transformation cost, and has popularization and application value.
