Description

TECHNICAL FIELD

[0001] The utility model relates to the field of battery, more specifically, it relates to a 1E grade battery protection plate. BACKGROUND

[0002] The grade is divided according to whether the structure, system and component of nuclear power plant execute safety function and its importance. The item that executes safety function belongs to nuclear safety grade, and the one that does not execute safety function belongs to non-nuclear safety grade. For mechanical equipment, safety grade is divided into four grades, wherein 1st grade is the most important, and 2nd, 3rd and 4th grades decrease in turn. For electrical and instrument equipment, safety grade is called 1E grade.

[0003] The failure form of battery includes plate corrosion, the continuous growth of the top of grid, the short circuit caused by the contact of polar column and grid upper frame, which leads to the shortening of battery life. At present, the main way in the industry is to increase the distance between the plate frame and the bottom of the busbar as much as possible at the beginning of design. Secondly, a positive plate protection sleeve is added to the positive plate upper frame. The former reduces the energy density of the battery, and in the latter scheme, the number of plates is large, which increases the cost.

[0004] The present application aims to improve and meet the safety needs of nuclear power. SUMMARY

[0005] The utility model overcomes the insufficient of the prior art battery plate that in order to avoid the growth of the plate, the plate frame and the busbar contact lead to short circuit, and provides a 1E grade battery protection plate, which avoids the direct contact between the plate frame and the busbar under the premise of not sacrificing the battery density and increasing the cost.

[0008] The protection plate is placed on the top of the plate, the tooth comb of the protection plate is inserted between the plate lugs, the plate frame and the busbar are separated by the insulation performance of the protection plate, so that short circuit is avoided.

[0009] Among them, the tooth comb plays a role in positioning the protection plate, the tooth comb is formed by the groove, the groove is inserted between the plate lugs, and the buckle connection is realized by the hook, so that the positioning of the protection plate is realized.

[0010] As preferred, the front end of the clamping hook is provided with a guide structure, which comprises an introduction bevel arranged on the clamping hook. The introduction bevel plays a role that, in the introduction process, the first contacted part is shorter in width and easier to insert, and through the guidance of the introduction bevel, the tooth comb is forced to deform and achieve the buckling connection with the polar plate.

[0011] As preferred, the plate body is provided with a plurality of acid passing holes. The acid passing holes pass through the acid liquid in the acid filling stage, and no acid accumulation occurs, and damage to the protection plate caused by liquid impact is also avoided.

[0012] As preferred, the acid passing holes are circular.

[0013] As preferred, the width of the groove is 0.2mm to 0.3mm larger than the width of the polar plate tab.

[0014] As preferred, the material of the protection plate is plastic.

[0029] Refer Figure 1 As shown, a protection board for a 1E-level storage battery includes a board body 1 and a comb 2 provided on one side of the board body 1. Among them, the comb 2 is located on the long side of the semi-body. The protection board is an electrical insulator. In some embodiments, the material of the protection board is plastic.

[0030] The comb 2 is formed by a plurality of parallel and equidistant grooves 5. The direction of the grooves 5 is perpendicular to the long side. The width, depth and the spacing between adjacent grooves 5 are adapted to the plate lug 7 of the 1E-level storage battery. In some embodiments, the width of the grooves 5 is 0.2 mm to 0.3 mm larger than the width of the plate lug 7.

[0031] The end of the comb 2 is provided with a hook 3. The front end of the hook 3 is provided with a guiding structure, and the guiding structure includes an inlet bevel 4 provided on the hook 3. The function of the inlet bevel 4 is that in the process of insertion, the width of the first contacted part is shorter and it is easier to insert. Through the guiding of the inlet bevel, the comb 2 is forced to deform and a snap connection with the plate 8 is achieved through the hook 3.

[0032] A plurality of pickling holes 6 are provided on the board body 1. The pickling holes 6 allow the acid solution to pass through during the acid filling stage, preventing acid accumulation and avoiding damage to the protection board caused by the impact of the liquid. Specifically, the pickling holes 6 are circular. The plastic material of the protection board can prevent the protection board from being corroded and rendered ineffective by the acid solution. In some embodiments, the pickling holes 6 are arranged in an array to evenly distribute stress.

[0033] The electrode plates 8 are arranged at equal intervals, and the edges of each electrode plate 8 are aligned, forming a plane for placing the protection board. The electrode plate tabs 7 extend from between the electrode plates 8 and are electrically connected to the bus bar 9. The bus bar 9 is suspended above the electrode plates 8 and is only electrically connected to the electrode plates 8 through the electrode plate tabs 7.

[0034] See Figure 2 、 Figure 3 As shown, during use, the protection board body 1 is placed on the electrode plates 8 and then extended under the bus bar plate, so that the groove 5 matches the substrate tab to perform a snap connection, thereby positioning the protection board through the substrate tab.

[0035] The protection board is placed on the top of the electrode plates 8, and the comb teeth 2 of the protection board are inserted between the electrode plate tabs 7. Through the insulation performance of the protection board itself, the frame of the electrode plates 8 and the bus bar 9 are separated, thus avoiding a short circuit.

[0036] Among them, the comb teeth 2 play a role in positioning the protection board. The comb teeth 2 are formed by the groove 5. The groove 5 is inserted between the electrode plate tabs 7, and a snap connection is achieved through the hook 3 to realize the positioning of the protection board.

[0037] The above-described embodiments are only preferred solutions of the present utility model and do not impose any form of limitation on the present utility model. There are other variations and modifications without exceeding the technical solutions described in the claims.
