Description

Technical Field

[0001] The invention relates to the technical field of storage batteries, and in particular to a self-protection high-performance storage battery pack. Background Art

[0002] After discharge, the internal active substances can be regenerated by charging - electrical energy is stored as chemical energy; when discharge is required, chemical energy is converted into electrical energy again. This type of battery is called a storage battery; when a storage battery is used for a long time, sediments are easy to appear in its electrolyte. In order to avoid the accumulation of sediments, it is often necessary to regularly clean the sediments in the electrolyte to ensure the performance of the storage battery. The main reasons for the sediments include impure electrolyte, dust or other impurities falling into the battery, and serious shedding of active substances. Impure electrolyte: If there are impurities in the electrolyte, these impurities may precipitate and form sediments; Dust or other impurities fall into the battery: Some external dust or other impurities may enter the battery, and these impurities will also precipitate to form sediments; Active substance shedding: If the active substances inside the battery fall off, sediments will also form in the electrolyte.

[0003] For example, the Chinese utility model patent with application number "202221866617.8" and name "A lead-acid battery pack" discloses a lead-acid battery pack, including a placement box and battery individuals, wherein the placement box has battery individuals arranged inside, and a box cover is arranged on the upper side of the placement box, a sealing gasket is connected to the lower side of the box cover, and connecting blocks are fixed on both sides of the box cover, and bolts are movably penetrated inside the connecting block.

[0004] Most of the existing lead-acid battery packs do not have the function of circulating, filtering and cleaning the sediment in the electrolyte. It is often necessary to manually remove the injection plug on the battery and then pour the electrolyte out of the injection port before filtering the sediment in the electrolyte. After treatment, the electrolyte is re-injected into the battery. This operation method is not only cumbersome and time-consuming, but also because the sediment is usually located at the bottom of the battery cavity and the injection port is mostly located at the top of the battery, when the battery is inverted to pour the electrolyte, the sediment needs to pass through multiple positive and negative plates. The sediment is easily adsorbed on the plates, making it difficult to efficiently clean the sediment. There are certain limitations and it needs to be improved. Summary of the invention

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0056] Working principle: When working, start the water pump 31, and the water pump 31 works to suck the electrolyte in the battery tank 13 into the T-shaped collecting pipe 35 through multiple liquid extraction branch pipes 36, and finally enters the liquid extraction main pipe 32. When the electrolyte flows in the liquid extraction main pipe 32, it will enter the long cylinder 45 in the filter tank 34, and the flowing electrolyte can be filtered through the filter frame 47 set at the bottom of the long cylinder 45. When the filter frame 47 at the bottom of the long cylinder 45 is blocked, the liquid between the long cylinder 45 and the liquid extraction main pipe 32 will increase, thereby pushing the piston plate 51 above the long cylinder 45 to move, and the piston plate 51 drives The connecting plate moves up, and through the cooperation of the cross plate 66, the L-shaped rod 65 and the fixing seat 64, the driving cylinder 61 is driven to move up. When the driving cylinder 61 moves up, the sliding rod 63 on the rotating rod 46 will move in the spiral groove 62 inside it, and drive the connecting rod 52 to move synchronously. The movement of the connecting rod 52 drives the filter frame 47 to move so as to replace the unblocked mesh for filtering. When the filter frame 47 is not blocked, but the impurities accumulated on the filter frame 47 block the passage of the liquid, the height of the piston plate 51 will continue to increase at this time. Through the connecting rod 52, the cross plate 66, the L-shaped rod 65 and the fixing seat 64, driving the rotation angle of the rotating rod 46 to continue to increase, so that the rectangular filter hole frame 48 on the filter screen frame 47 moves to the bottom of the long cylinder 45, at this time, the impurities blocked in the long cylinder 45 will be squeezed into the rectangular filter hole frame 48, so that the liquid pressure in the long cylinder 45 is released, and the restoring force of the abutment spring 53 squeezed by the piston plate 51 pushes the piston plate 51 to reset, and the piston plate 51 drives the driving cylinder 61 to move downward synchronously through the cross plate 66, the L-shaped rod 65 and the fixing seat 64, so that the connecting rod 52 rotates in the opposite direction, and the rectangular filter hole frame 48 containing impurities moves on the bottom plate 49, Until the rectangular filter hole frame 48 moves to the through hole 410 on the bottom plate 49, the impurities in the rectangular filter hole frame 48 fall into the waste space 43 for separation, and the filtered electrolyte will fall into the filter space 42, and be introduced into the T-type shunt pipe 37 by the reflux main pipe 33, and finally flow into the battery slot 13 through the multiple reflux branch pipes 38 provided on the T-type shunt pipe 37. After the electrolyte enters the battery slot 13 again, the stirring impeller 2 provided therein will be driven to rotate by the flow of water, so that the sediment attached to the bottom wall of the battery slot 13 can be moved, thereby performing circulation filtration;

[0057] When the electrolyte flows in the reflux main pipe 33, it will drive the stirring impeller 2 in the fixed cylinder 71 to rotate, and the rotation of the stirring impeller 2 drives the rotating shaft 93 to rotate. The rotating shaft 93 is connected to the reciprocating screw 94 and drives it to rotate synchronously. At this time, the threaded block sleeve 95 set on the reciprocating screw 94 will move back and forth under the guidance of the guide rod 92, and the threaded block sleeve 95 moves through the cross frame 96 to drive the cleaning brush 97 and the driving frame 102 on the fixed frame 101 to move synchronously. When moving, the driving frame 102 first contacts the cross bar 85 on the fixed block 83, and Pull the cross bar 85 upward, and the upward movement of the cross bar 85 can drive the unblocking ejector pin 82 in the lead-acid battery 11 to move upward synchronously through the fixed block 83 and the square rod 81, so as to unblock the vent hole 16 on the filling plug 15. At this time, the cleaning brush 97 will move to the blocked vent hole 16, and after sweeping away the blockage just pushed out by the unblocking ejector pin 82, the driving frame 102 will be separated from the cross bar 85 again, and the fixed block 83 connected to the cross bar 85 will drive the unblocking ejector pin 82 to reset under the action of the supporting spring 84, so that the vent hole 16 is exposed for ventilation.
