Description

Technical Field

[0001] The present invention relates to the field of temperature measuring devices, and more specifically, to an anti-shake power UPS battery pack embedded temperature measuring device. Background Art

[0002] At present, the normal operation of the battery pack is directly related to whether the UPS uninterruptible power supply can stably and continuously supply power externally. Therefore, the service life of the battery pack is crucial. During operation, the battery packs are generally placed together in a closed dedicated battery cabinet, which is not conducive to normal inspection and monitoring by users. During normal operation, since the battery is connected to the UPS charging circuit, the charging and discharging of the battery will cause the temperature of the battery itself to rise, resulting in heat generation. When the temperature is too high, it will directly damage the battery, or cause dangerous situations such as short circuit and sparking, battery expansion, damage to supporting equipment, and even explosion, seriously affecting the safe operation of the equipment.

[0003] However, during use, the operating temperature of the battery cannot be monitored in real time, so the battery cannot be maintained and replaced in a timely manner, resulting in a shortened service life of the battery. Moreover, the voltage of the UPS battery charging circuit is relatively high, and traditional temperature measuring devices are prone to leakage during use, with low safety performance.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will be further described in detail below with reference to the drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0018] As Figure 1A kind of anti-surge power failure UPS battery two-group embedded temperature measuring device shown in the figure, including a battery box 1 and a UPS battery 2 arranged inside the battery box 1. The bottom of the UPS battery 2 is fixedly connected to the bottom of the inner cavity of the battery box 1 through a cushion block. There is a gap between the bottom of the UPS battery 2 and the bottom of the battery box 1 to facilitate heat dissipation at the bottom of the UPS battery 2;

[0019] A heat sink plate 3 movably connected to the inner wall of the battery box 1 is arranged at the top of the UPS battery 2. A heat conductive silica gel pad 4 is attached to the bottom of the heat sink plate 3. Both the battery box 1 and the cushion block are made of insulating materials. With the movably connected heat sink plate 3, when the heat sink plate 3 moves downward onto the UPS battery 2, the heat conductive silica gel pad 4 below the heat sink plate 3 will be attached to the UPS battery 2. Since both the heat conductive silica gel pad 4 and the cushion block are made of insulating materials, no electric leakage will occur during the temperature measurement process of the entire UPS battery 2;

[0020] As Figure 2 shown, a connecting rod 5, a return spring 6 and a main rod 7 are installed above the heat sink plate 3. A connecting sleeve 8 is sleeved on the upper end of the connecting rod 5. The inner cavity top of the battery box 1 is fixedly installed with a circuit board 10. The upper end of the connecting sleeve 8 is fixedly installed on the circuit board 10. During the movement of the heat sink plate 3, the connecting rod 5 moves within the connecting sleeve 8. The connecting sleeve 8 is fixed on the circuit board 10, and the circuit board 10 is fixed on the inner cavity top of the battery box 1. The connecting rod 5 and the connecting sleeve 8 can limit the movement of the heat sink plate 3 to make its movement smoother;

[0021] A plurality of temperature sensors 12 are connected to the circuit board 10 through wires. The plurality of temperature sensors 12 are attached to the top of the heat sink plate 3. A microprocessor is installed on the circuit board 10. The output end of the temperature sensor 12 is connected to the A / D conversion of the microprocessor. A display screen 14 and a control panel 15 are arranged on the top of the battery box 1. A plurality of buttons are arranged on the control panel 15. The microprocessor is also connected to the display screen 14;

[0022] After the heat conductive silica gel pad 4 at the bottom of the heat sink plate 3 is attached to the UPS battery 2, the temperature of the heat sink plate 3 will increase over time and finally level with the temperature of the UPS battery 2. At this time, the temperature information detected by the temperature sensor 12 is the temperature information of the UPS battery 2. After this information is converted into a digital signal through A / D conversion, it is displayed on the display screen 14 through the microprocessor;

[0023] A plurality of heat dissipation holes 16 are opened on the outer walls of the battery box 1 on both sides of the UPS battery 2. A heat dissipation fan 13 fixed to the inner wall of the battery box 1 is arranged at the inner end of the heat dissipation holes 16. The arranged heat dissipation holes 16 and heat dissipation fans 13 can cool the UPS battery 2 to make the operation of the entire device more stable;

[0024] The main rod 7 is arranged in the middle of the surface of the heat sink 3. The reset springs 6 and the connecting rods 5 are both provided in multiple numbers and are respectively arranged on both sides of the main rod 7. This design structure is more stable and reduces the occurrence of faults;

[0025] As Figure 1-2 shown, a magnet 9 is embedded inside the top end of the main rod 7, and an electromagnet 11 is installed at a position directly above the main rod 7 on the circuit board 10. The magnetic field directions of the electromagnet 11 and the magnet 9 are opposite. When it is necessary to detect the temperature, the electromagnet 11 will generate a magnetic field, act on the magnet 9 to push the magnet 9 to move downward, and then drive the main rod 7 and the heat sink 3 to move downward. During the downward movement, the reset spring 6 expands until the heat conduction silicone pad 4 at the bottom of the heat sink 3 fits onto the surface of the UPS battery 2. After the detection is completed, the electromagnet 11 is powered off, the magnetic field disappears, the reset spring 6 retracts, and under the action of the reset spring 6, the heat sink 3 moves upward to reset, and the heat conduction silicone pad 4 is separated from the UPS battery 2;

[0026] So that during the temperature measurement of the UPS battery 2, the temperature measurement device is completely insulated from the UPS battery 2, and the temperature transfer efficiency is high, which will not affect the temperature measurement. On the premise of ensuring the temperature measurement efficiency, the safety performance is improved and the reliability is strong.

[0027] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
