Description
Technical Field
[0001] The utility model relates to the technical field of nickel-hydrogen battery control, in particular to a control device for preventing nickel-hydrogen batteries from over-discharging. Background Art
[0002] Nickel-hydrogen batteries are divided into rechargeable and non-rechargeable types. Generally speaking, rechargeable nickel-hydrogen batteries do not need to be fully discharged before being recharged, and over-discharge should be avoided. When the battery is discharged to below 1V-0.9V, it may cause permanent damage to the battery, reduce the capacity, or even be unable to be recharged. In order to prevent the problem of over-discharge of nickel-hydrogen batteries, application number: 201920681392.0 discloses a control device for preventing over-discharge of nickel-hydrogen batteries, including nickel-hydrogen batteries, control devices and loads, the control signal output by the control unit is connected to the receiving end of the alarm, the output end of the alarm is electrically connected to a speaker integrated thereon through a wire, and a temperature sensor is also installed on the outer surface of the nickel-hydrogen battery; the scheme provides an alarm, a temperature sensor and a display screen, so that the user can directly and quickly judge whether the operating temperature of the nickel-hydrogen battery is normal according to the content observed on the display screen, and can effectively and timely prevent the nickel-hydrogen battery from exploding or burning due to short circuit. In the case of over-discharge of the nickel-hydrogen battery, the control unit cuts off the nickel-hydrogen battery. After the battery and the load are connected, the alarm is started, and the alarm signal is sent out through the speaker integrated in the alarm, so that the staff around the nickel-hydrogen battery can turn off the nickel-hydrogen battery itself, thereby avoiding a long-term short circuit. The outer steel shell, protective outer box, elastic band, inner tank box, elastic heat conductive plate and elastic fixing plate arranged inside can effectively block the fragments generated by the explosion of the nickel-hydrogen battery. The elastic fixing plate, elastic band and outer steel shell can intercept the fragments generated by the explosion of the nickel-hydrogen battery to prevent the explosion of the nickel-hydrogen battery from harming the surrounding people and environment. In addition, an inner tank box filled with dry powder is used. Once the nickel-hydrogen battery burns due to a short circuit, the elastic fixing plate melts due to high-temperature combustion, thereby opening the opening of the inner tank box blocked by the elastic fixing plate, so that the dry powder inside the inner tank box enters the nickel-hydrogen battery placement slot through the opening, thereby extinguishing the burning nickel-hydrogen battery, thereby achieving the purpose of preventing the spread of combustion, and once the dry powder cannot be extinguished, the water filled inside the protective outer box can also block the spread of the fire again;
[0003] The control device for preventing over-discharge of nickel-hydrogen batteries disclosed in the above patent can monitor the discharge of nickel-hydrogen batteries, and when over-discharge is detected, the control unit cuts off the connection between the nickel-hydrogen battery and the load, stops the discharge, and reminds personnel to turn off the nickel-hydrogen battery itself through an alarm. In addition, it can block the nickel-hydrogen battery in time when it explodes, thereby reducing the spread of fire. However, the control device for preventing over-discharge of nickel-hydrogen batteries disclosed in the above patent still has some shortcomings during use: 1. Although it can achieve an effective blocking effect by setting up multiple boxes, it will affect the normal heat dissipation of the nickel-hydrogen battery, and there is a situation where the forward use of the nickel-hydrogen battery is affected by untimely heat dissipation; 2. The nickel-hydrogen battery is directly placed in the box, lacks a separate fixed structure, and the nickel-hydrogen battery will collide with the box during carrying, thereby causing damage to the nickel-hydrogen battery; it cannot meet the use requirements. Based on the above situation, improvements are made on the basis of the above patent, so we propose a control device for preventing over-discharge of nickel-hydrogen batteries. Utility Model Content

[0028] Working principle: when in use, the cover plate 105 is opened before use to place the nickel-hydrogen battery 106 in the plastic shell 103, and at this time, the bottom of the nickel-hydrogen battery 106 is in active contact with the top of the two anti-skid support blocks 4, and the nickel-hydrogen battery 106 is supported by the support plate 1 and the two anti-skid support blocks 4. After placement, the cover plate 105 is fixed to the top of the outer steel shell 100, and then the T-shaped screw 8 is rotated forward. The T-shaped screw 8 moves downward while rotating, and the T-shaped screw 8 drives the pressing plate 7 to move downward, and the pressing plate 7 drives the two heat-conducting blocks 6 to move downward.

[0029] When the nickel-hydrogen battery 106 is in normal use, the control unit 107 monitors the discharge of the nickel-hydrogen battery 106 and performs a power-off operation in time when over-discharge is detected. At the same time, the control unit 107 controls the sound and light alarm 110 to send out a sound and light alarm to remind personnel to turn off the nickel-hydrogen battery 106. The specific detection and power-off principle is mentioned in the patent document of application number: 201920681392.0, which will not be elaborated here;
[0030] During normal use of the nickel-hydrogen battery 106, the temperature sensor 108 detects its temperature and transmits a signal to the control unit 107. When it is detected that the temperature of the nickel-hydrogen battery 106 reaches the temperature that needs heat dissipation, the control unit 107 controls the air cooler 3 to turn on. The air cooler 3 extracts external gas and discharges cold air into the connecting pipe 2. The cold air inside the connecting pipe 2 is discharged through the support plate 1 and multiple air blowing pipe heads 5 to blow the nickel-hydrogen battery 106. Under the blowing of the cold air, the heat inside the plastic shell 103 is discharged to the outside through multiple vents 10, thereby achieving the purpose of automatically and timely assisting heat dissipation when the temperature of the nickel-hydrogen battery 106 is high, without affecting the positive use of the nickel-hydrogen battery 106, and can effectively avoid the situation where the nickel-hydrogen battery 106 is affected by the excessively high temperature.
[0031] When the temperature sensor 108 detects that its temperature is too high and reaches the explosion temperature value, the control unit 107 controls the electric telescopic rod 12 to start in the reverse direction, and controls the cooling fan 3 to be turned off. The output shaft of the electric telescopic rod 12 drives the sealing plate 11 and the sealing pad 13 to move downward. The sealing pad 13 moves downward until it is in close contact with the top of the cover plate 105. At this time, the sealing pad 13 and the sealing plate 11 block the multiple vents 10. The method of automatically blocking the vents 10 when an explosion is detected can effectively prevent debris from bursting out, thereby improving the safety of use.
[0032] When the temperature is too high, the plastic shell 103 melts, exposing the dry powder 104 for fire extinguishing. At the same time, the multi-layer barrier of the inner tank box 102, the protective box 101 and the outer steel shell 100 can effectively prevent the spread of fire. The multi-layer barrier method has also been mentioned in the patent document with application number 201920681392.0, so it will not be elaborated here.
