Description

Technical Field

[0001] This application belongs to the field of environmentally friendly storage battery technology, specifically relating to a solar energy storage battery with an acid filter. Background Technology

[0002] In existing technology, lead-acid batteries are a traditional type of rechargeable battery. Their electrodes are primarily made of lead and its oxides, and the electrolyte is a sulfuric acid solution. The working principle of lead-acid batteries is based on the chemical reaction between lead and sulfuric acid, achieving the conversion between electrical energy and chemical energy through the redox reaction of the electrodes. Lead-acid batteries have advantages such as low cost, recyclability, mature technology, and good safety performance, and therefore have been widely used in many fields.

[0003] In existing technologies, during the use of lead-acid batteries, the acid inside the battery body will be discharged from the battery body along with the gases produced by the reaction of the battery fluid as the service life increases. On the one hand, the discharge of lead-containing acid from the battery body will damage the environment. On the other hand, the process of acid evaporation will cause the loss of acid inside the battery body, increase the frequency of acid replenishment, increase acid consumption, increase the maintenance cost of lead-acid batteries, and reduce the service life of lead-acid batteries. Therefore, in order to improve the environmental protection and service life of lead-acid batteries, it is urgent to make improvements to existing lead-acid batteries. Utility Model Content

The flow guiding component 5 is used to discharge the gas generated during the discharge of the battery body 4 into the chamber 3, and the trapping component 6 is used to trap the acid entrained in the gas generated during the discharge of the battery body 4.

[0025] This application provides a solar energy storage battery with an acid filter, comprising a main shell, a cover fitted onto the main shell, a cavity formed by the main shell and the cover, a battery body disposed within the cavity, a flow guiding component disposed on the main shell and communicating with the cavity, and a trapping component disposed on the flow guiding component. By setting the trapping component on the flow guiding component, the gas generated by the battery body during discharge can be guided to the outside of the main shell, and the acid entrained in the gas generated by the battery body during discharge can be trapped. The trapped acid can be returned to the cavity through the flow guiding component, thereby preventing acid leakage to the outside of the main shell, reducing acid loss, reducing the frequency of replenishing acid to the battery body, reducing the maintenance cost of lead-acid batteries, and extending the service life of lead-acid batteries. It has the advantages of simple structure, convenient use, energy saving and environmental protection, and easy promotion and implementation.

[0026] In this embodiment, the flow guiding component 5 includes several flow guiding plates 50 extending from the cavity 3 to the side wall of the outer shell body 1, an exhaust port 51 formed by the several flow guiding plates 50, and a sealing plug matched on the exhaust port 51.

The average pore diameter of the pores is 1μm so that the gas generated during the discharge of the battery body 4 can be discharged from the chamber 3.

[0028] In actual implementation, the gas containing acid generated during the discharge of the battery body 4 passes through the interception component, which traps the acid. After passing through the interception component, the gas is discharged to the outside through the vent, thus preventing acid leakage from the battery body.

[0029] In this embodiment, the interception component 6 includes a mounting groove 60 on the side of the guide plate 50 near the outer shell body 1, and an interception mesh 61 embedded in the mounting groove 60. The interception mesh 61 has a multi-layer structure and is used to intercept the acid liquid trapped in the gas generated during the discharge process of the battery body 4.

[0030] In actual implementation, the deflector is made of polytetrafluoroethylene.

[0031] In this embodiment, the guide plate 50 is inclined relative to the chamber 3, and the angle between the guide plate 50 and the chamber 3 is defined as X. X satisfies the following relationship: 45°≤X≤60°.

[0032] In actual implementation, X = 45°.

[0033] In this embodiment, the interception mesh 61 includes a coarse filter layer 610, an adsorption layer 611, and an interception layer 612 stacked sequentially from the inside to the outside. The coarse filter layer 610 and the interception layer 612 are made of the same material. The pore size of the coarse filter layer 610 is larger than that of the adsorption layer 611, and the pore size of the adsorption layer 611 is larger than that of the interception layer 612.

[0034] In this embodiment, both the coarse filter layer 610 and the retention layer 612 are made of PTFE film.

[0035] The adsorption layer 611 is made of activated carbon.

[0036] In this embodiment, the pore size of the coarse filter layer 610 ranges from 5μm to 10μm.

[0037] In actual implementation, the porosity of the PTFE film is 0.25.

[0038] In practice, PTFE films exhibit selective permeability; detailed information can be found at the following website:

[0039] http: / / www.wxxj.com / cn241.html

[0040] This technology is familiar to those skilled in the art and will not be described in detail here.

[0041] In actual implementation, by designing the pore size and porosity of the PTFE film, the gas generated during the discharge of the battery body 4 can pass through the interception component, while the acid encased in the gas cannot pass through the interception component, thereby achieving acid interception and preventing acid leakage to the outside world, making the battery meet environmental protection requirements.

[0042] In this embodiment, a power supply device 7 electrically connected to the battery body 4 is also included, which is used to charge the battery body 4.

[0043] In this embodiment, the power supply device 7 includes an angle adjustment component 70 movably mounted on the outer shell body 1, and a solar panel 71 detachably mounted on the angle adjustment component 70. The angle adjustment component 70 is used to adjust the angle between the solar panel 71 and the outer shell body 1.

[0044] In this embodiment, the angle adjustment component 70 includes a rotating shaft 700 located at the bottom of the outer shell body 1, and a connecting ear 701 rotatably mounted on the rotating shaft 700. The solar panel 71 is detachably mounted on the connecting ear 701. The connecting ear 701 can drive the solar panel 71 to rotate relative to the outer shell body 1 around the rotating shaft 700, so as to adjust the included angle between the solar panel 71 and the outer shell body 1.

[0045] In practice, by setting up solar panels, the battery body can be charged, thus expanding the applicability of lead-acid batteries.

[0046] This application provides a solar energy storage battery with an acid filter, comprising a main shell, a cover fitted onto the main shell, a cavity formed by the main shell and the cover, a battery body disposed within the cavity, a flow guiding component disposed on the main shell and communicating with the cavity, and a trapping component disposed on the flow guiding component. By setting the trapping component on the flow guiding component, the gas generated by the battery body during discharge can be guided to the outside of the main shell, and the acid entrained in the gas generated by the battery body during discharge can be trapped. The trapped acid can be returned to the cavity through the flow guiding component, thereby preventing acid leakage to the outside of the main shell, reducing acid loss, reducing the frequency of replenishing acid to the battery body, reducing the maintenance cost of lead-acid batteries, and extending the service life of lead-acid batteries.
