Description

Technical Field

[0001] This invention relates to the field of battery technology, and more specifically, to a battery capable of self-monitoring. Background Technology

[0002] A lead-acid battery is a type of rechargeable battery whose electrodes are primarily made of lead and its oxides, and whose electrolyte is a sulfuric acid solution. In the discharged state, the positive electrode is mainly composed of lead dioxide, and the negative electrode is mainly composed of lead; in the charged state, both the positive and negative electrodes are mainly composed of lead sulfate. The conversion between electrical energy and chemical energy is achieved through the chemical reaction between the active materials of the positive and negative electrodes and sulfuric acid during charging and discharging.

[0003] Lead-acid batteries electrolyze water during charging to produce hydrogen and oxygen. Valve-regulated batteries use an "oxygen cycle" technology to recombine most of the gases into water, but excess gas still needs to be released. Under normal circumstances, the safety valve rarely opens, and even when it does, the volume of gas released is very small. However, when malfunctioning, such as during overcharging, high temperature, or battery aging, the opening frequency of the safety valve increases significantly, and the amount of gas released also increases dramatically. Currently, existing battery systems rarely monitor the gas released from the safety valve during use, resulting in a lack of timely monitoring when abnormal opening frequency leads to abnormal gas release. Timely monitoring of the released gas volume would greatly improve battery safety. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a storage battery capable of self-monitoring.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a storage battery, comprising a control unit, a housing, a first partition unit, a second partition unit, a cover plate, and a plurality of valve-regulated lead-acid batteries; the first partition unit comprises a first separator and a first surrounding frame; the second partition unit comprises a second separator and a second surrounding frame; the second surrounding frame has a mounting groove and a first pressure sensor, a valve unit is mounted in the mounting groove, and the second separator has a cross-shaped through groove.

[0006] Furthermore, the first partition unit is fixedly connected to the box body, the second partition unit is fixedly connected to the first partition unit, and the cover plate is fixedly connected to the second partition unit.

[0007] Furthermore, multiple valve-regulated lead-acid batteries are installed inside the enclosure.

[0008] Furthermore, the first surrounding frame surrounds the first partition and is fixedly connected to the first partition; the second surrounding frame surrounds the second partition and is fixedly connected to the second partition.

[0009] Furthermore, multiple valve-regulated lead-acid batteries are connected in series.

[0010] In some embodiments, multiple valve-regulated lead-acid batteries are connected in a series-parallel combination.

[0011] Furthermore, a rectangular frame-shaped first sealing portion is provided between the first enclosure frame and the housing.

[0012] Furthermore, a rectangular frame-shaped second sealing portion is provided between the first enclosure frame and the second enclosure frame.

[0013] Furthermore, a rectangular frame-shaped third sealing portion is provided between the second enclosure frame and the cover plate.

[0014] Furthermore, the first sealing part, the second sealing part, and the third sealing part are all made of rubber material.

[0015] Furthermore, the top of the box has a first threaded hole, and the first enclosure frame, the second enclosure frame, and the cover plate all have bolt through holes. The first fixing bolt passes through the bolt through holes in the cover plate, the second enclosure frame, and the first enclosure frame and engages with the first threaded hole to fix the cover plate, the second enclosure frame, the first enclosure frame, and the box together.

[0016] Furthermore, the valve unit is a solenoid valve.

[0017] Furthermore, each valve-regulated lead-acid battery has a sealing cover over its safety valve. The top of the sealing cover has a connecting hole, and the tops of all the sealing covers are sealed against the first partition. The first partition has multiple vent holes communicating with the connecting hole. A strip cover is located between the first and second partitions, and a rotating shaft is fixedly connected to the strip cover. A second pressure sensor is located at the strip cover. A mounting bracket is fixed between the second partition and the cover plate. A moving unit is installed at the mounting bracket. The mounting bracket includes two first upper plates with first upper sliding grooves and two second upper sliding grooves. The unit comprises a second upper plate, two first lower plates with first lower grooves, two second lower plates with second lower grooves, and four end plates on which electric winding devices are mounted. The first lower plates have first notches that allow the rotating shaft to pass through, and the second lower plates have second notches that allow the rotating shaft to pass through. The moving unit includes a movable seat and four sliders connected to the movable seat. An electric telescopic rod is mounted on the movable seat. The electric telescopic rod is connected to a rotary drive unit that can drive the rotating shaft to rotate via a connecting plate. A pull rope is connected between the movable seat and each electric winding device.

[0018] Thus, the moving unit can be driven by an electric winding device, and the position of movement can be precisely controlled.

[0019] Furthermore, both the first and second sliding grooves have hemispherical grooves, and the bottom end of the slider has a blind hole. The end of the blind hole is connected to a movable column by a spring, and the bottom end of the movable column is hemispherical.

[0020] When the electric winding device stops driving, the bottom end of the movable column can be inserted into the hemispherical groove. When the electric winding device drives the rope, the bottom end of the movable column can disengage from the hemispherical groove. This makes the positioning of the slider more accurate at each workstation.

[0021] Furthermore, the two first upper plates are parallel to each other, the two first lower plates are parallel to each other, the two second upper plates are parallel to each other, and the two second lower plates are parallel to each other.

[0022] Furthermore, the first upper plate and the second upper plate are perpendicular.

[0023] Furthermore, the first lower plate and the second lower plate are perpendicular.

[0024] Furthermore, the rotary drive unit is a motor.

[0025] Furthermore, the number of vent holes is equal to the number of sealing covers, and the two correspond one-to-one.

[0026] Furthermore, the sealing cover and the valve-regulated lead-acid battery are fixedly connected by sealant.

[0027] Furthermore, the second partition has a second threaded hole, and the end plate has a countersunk hole. The second fixing bolt passes through the countersunk hole and the second threaded hole to fix the end plate to the second partition.

[0028] Furthermore, the width of the first notch is equal to the width of the second notch.

[0029] Furthermore, the cross-section of the slider is a square with chamfers, and the width of the slider cross-section is greater than the width of the first notch.

[0030] Thus, the slider can cross the first notch and the second notch.

[0031] Furthermore, the top end of the slider can slide within the first upper sliding groove and the second upper sliding groove, and the bottom end of the slider can slide within the first lower sliding groove and the second lower sliding groove.

[0032] Furthermore, the movable seat includes a seat body and four connecting blocks that connect the seat body and the slider, the seat body having a receiving cavity into which one end of the rotary drive unit is inserted.

[0033] The base and the rotary drive unit are not connected, so the rotary drive unit can be raised and lowered relative to the base under the drive of the electric telescopic rod, thereby allowing the strip cover to descend and seal a row or column of vents.

[0034] Furthermore, four semi-circular rings are fixed at the base, and there is a one-to-one correspondence between the four semi-circular rings and four electric winding devices. The pull ropes are connected between the corresponding semi-circular rings and the electric winding devices.

[0035] Furthermore, the electric telescopic rod has four sections, and the connecting plate has four sections.

[0036] Furthermore, the strip cover has an abutting convex edge and reinforcing ribs.

[0037] Furthermore, the abutting protrusion has a first sealing ring; the lower surface of the first partition has a plurality of second sealing rings, each of which includes a vent hole.

[0038] Furthermore, multiple valve-regulated lead-acid batteries are arranged in a rectangular array.

[0039] Furthermore, the multiple vents are distributed in a rectangular array, divided into multiple rows and multiple columns. The direction of the row is the same as the length direction of the first upper plate, and the direction of the column is the same as the length direction of the second upper plate. The distance between the two vents at both ends of a row is equal to the distance between the two vents at both ends of a column.

[0040] Furthermore, the strip cover can cover a row of vents or a column of vents.

[0041] Furthermore, one row has 5 valve-regulated lead-acid batteries, and one column has 9 valve-regulated lead-acid batteries.

[0042] Furthermore, the ventilation holes in each row are evenly spaced; the ventilation holes in each column are evenly spaced.

[0043] Furthermore, the second enclosure has two mounting grooves located on the outside of the second enclosure.

[0044] Furthermore, there are two first pressure sensors, with the first pressure sensor installed inside the second enclosure frame; and two second pressure sensors are located at the strip cover.

[0045] Two pressure sensors are installed to better detect air pressure.

[0046] Furthermore, both the first and second partitions are square.

[0047] Furthermore, the housing includes four side panels, two of which have through holes and the other two of which have strip-shaped through grooves.

[0048] Thus, the through-hole can be used to transport the housing, and the strip-shaped through-slot can be used to insert the wires connecting the electrode posts.

[0049] Beneficial effects:

[0050] 1. The battery of this application can monitor the amount of gas released in a timely manner, which is more conducive to the safe operation of the battery.

[0051] 2. The battery in this application uses a strip cover to cover each row and column of vent holes for testing. Combined with the coordinate positioning method, it can quickly locate the position of valve-regulated lead-acid batteries that are releasing abnormal gas, which greatly improves the efficiency of fault diagnosis.

[0070] Working Principle: In this application, the battery has a sealed connection between the sealing cover and the first separator. For ease of description, the space between the first and second separators is referred to as the first space, and the space between the second separator and the cover plate is referred to as the second space. The first and second spaces are connected by a cross-shaped through groove. The space inside each sealing cover is connected to the first space. During normal use, the valve unit is open, and there is a gap between the strip cover and the first separator (the strip cover is actually in an unused state). When testing is required, the valve unit is closed (testing will also stop when the measured value of the first pressure sensor is greater than the threshold, and the valve unit will be opened to actively release pressure, thereby ensuring safe use). After a period of time (e.g., 1-2 days), when the measured value of the first pressure sensor is within a reasonable range, it indicates that each valve-regulated lead-acid battery has not released excessive gas, and is working normally in the dimension of not releasing excessive gas. When the reading of the first pressure sensor exceeds the reasonable range, it indicates that a valve-regulated lead-acid battery is releasing excessive gas. Next, a row of vents is covered with a strip cover, and the gas pressure inside the strip cover is checked for a period of time. If it is normal, it means that the gas release from this row of valve-regulated lead-acid batteries is normal. If the pressure is too high, it means that a valve-regulated lead-acid battery in this row is releasing excessive gas. The same method is used to cover each row of vents for testing. Then, the strip cover is used to cover each column of vents for testing. The moving unit can move under the drive of multiple electric winding devices, and the direction of the strip cover can be adjusted by rotating 90 degrees under the drive of the rotation drive unit. By checking each row and column of vents, batteries with abnormal gas release can be identified. For example, if an abnormal battery is found, this method is equivalent to finding the horizontal and vertical coordinates of the battery, thus identifying the faulty battery and facilitating more targeted maintenance.

[0071] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
