Description
Technical Field
The utility model belongs to the technical field of the battery, concretely relates to valve-regulated lead acid battery case.
Background
The valve-controlled sealed lead-acid accumulator is a chemical energy accumulator and may be used widely in automobile, locomotive, tank, power station, ship, underwater vehicle, etc. owing to its long service life, stable performance, high safety and reliability, low cost and other advantages.
However, the problem of acid leakage of the cover of the storage battery frequently occurs in the large-scale use process of the valve-controlled sealed lead-acid storage battery, if one storage battery in the storage battery has acid leakage, the insulation resistance of the whole group of storage batteries to the ground is sharply reduced, the leakage current is obviously increased, and the safety of equipment and personnel is harmed.
The existing epoxy glue sealing between the tank covers of the valve-controlled sealed lead-acid storage battery adopts a single-layer sealing mode, and the shell of the storage battery is designed into a single-layer sealing structure. The storage battery with a single-layer sealing structure is easy to have the hidden troubles of manufacturing defects such as air bubbles, glue shortage and the like and sealing quality in the sealing of the storage battery tank cover.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a valve regulated lead acid battery shell of double-deck seal structure of capping according to prior art's not enough.
The utility model provides a technical scheme that its technical problem adopted is: a valve-regulated lead-acid storage battery shell comprises a plastic storage battery groove, a storage battery cover and other accessories, wherein the storage battery cover is arranged at the opening of the top of the storage battery groove, a convex edge extending downwards is arranged at the bottom of the storage battery cover, a groove is correspondingly formed in the top end face of the side wall of the storage battery groove, the convex edge is inserted into the groove, a gap of 0.5-1.5 mm is formed between the convex edge and the groove, a lower sealing adhesive layer is filled in the gap, and an upper sealing adhesive layer is arranged in an area surrounded by cured materials between the outer wall of the storage battery cover and the inner wall of the storage battery groove and above the lower sealing adhesive layer.
The top of the accumulator groove of the valve-regulated lead-acid battery shell is flush with the top surface of the accumulator cover.
The upper sealing adhesive layer and the lower sealing adhesive layer of the valve-regulated lead-acid storage battery shell are both made of epoxy resin.
Four side walls of the battery cover of the valve-regulated lead-acid battery shell are provided with inclined planes, and the valve-regulated lead-acid battery shell is provided with an inverted trapezoidal section.
The utility model has the advantages that: the storage battery with the double-layer sealing structure is formed on the basis of the upper sealing adhesive layer and the lower sealing adhesive layer, so that the problem of traditional sealing failure is solved, and defects existing in the encapsulating process of the sealant can be eliminated; compared with a single-layer sealing structure of the slot cover, the sealing path of the double-layer sealing structure of the slot cover is multiplied, and the sealing reliability between the slot covers is obviously improved.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic view of the structure of the battery cover of the present invention.
The figures are numbered: 1-accumulator tank, 2-lower sealant layer, 3-upper sealant layer, and 4-accumulator cover.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to fig. 1 and fig. 2, the utility model discloses a valve-regulated lead acid battery shell, including plastics battery jar 1 and battery cover 4 and other accessories of setting at battery jar 1 open-top portion, this patent battery shell has upper and lower double-deck seal structure, and upper strata and lower floor all adopt sealed glue filling sealed.
In order to realize double-layer sealing, the bottom of the storage battery cover 4 is provided with a convex edge extending downwards, the top end face of the side wall of the storage battery groove 1 is correspondingly provided with a groove, the convex edge is inserted into the groove, a gap of 0.5-1.5 mm exists between the convex edge and the groove, the gap is filled with a lower sealing adhesive layer 2, and an upper sealing adhesive layer 3 is arranged in a region surrounded by a condensate between the outer wall 4 of the storage battery cover and the inner wall of the groove of the storage battery groove 1 and above the lower sealing adhesive layer 2. Wherein the top opening of the storage battery groove 1 is flush with the top large plane of the storage battery cover 4. The upper sealant layer 3 and the lower sealant layer 2 are both epoxy resin.
This patent battery jar 1's the glue recess outer wall of gluing is higher than the inner wall, glues more than the height of glue recess outer wall of traditional battery jar 1 and highly long more than 10mm, and the biggest overall dimension of 4 cross sections of battery cover is less than the biggest overall dimension of 1 cross section of battery jar simultaneously, and four lateral walls of battery cover 4 design into the inclined plane, have the trapezoidal section of falling. Compared with a common single-layer sealing structure, the double-layer sealing structure of the storage battery shell can improve the sealing reliability between the storage battery groove 1 and the cover by 2 orders of magnitude, and the storage battery cover 4 is sunk into the storage battery groove 1, so that the phenomenon that the storage battery cover 4 is directly impacted by external force to cause the reduction or failure of the sealing performance between the storage battery groove 1 and the cover is avoided.
Before the cover of the storage battery groove 1 is assembled, a certain amount of epoxy sealant is firstly injected into the sealant groove of the storage battery groove 1, then the lower edge of the storage battery cover 4 is assembled into the groove of the storage battery groove 1, so that the convex edge of the storage battery cover 4 is inserted into the sealant groove of the storage battery groove 1 to form a lower sealant layer 2, namely, the first sealing. After the lower sealant layer 2 is cured, a region surrounded by the inner wall of the groove of the battery container 1, the outer side wall of the battery cover 4 and the upper surface of the cured material of the lower sealant layer 2 is formed at the top of the lower sealant layer, and a second seal is formed after the upper sealant layer 3 is filled.
The above embodiments are merely illustrative of the principles and effects of the present invention, and some embodiments may be applied, and it will be apparent to those skilled in the art that a plurality of modifications and improvements may be made without departing from the inventive concept of the present invention, and all of these modifications and improvements fall within the protection scope of the present invention.
