Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery charging technology, specifically to a simple lead-acid battery charging and energy storage box. Background Technology

[0002] In today's energy storage and utilization field, lead-acid batteries are widely used in energy storage systems due to their advantages such as low cost, mature technology, and strong adaptability to high and low temperatures. They are commonly used in emergency power supplies and grid peak shaving and valley filling scenarios. However, during charging, lead-acid batteries undergo complex electrochemical reactions. For example, lead dioxide on the positive electrode and spongy lead on the negative electrode react with the electrolyte to form lead sulfate and water, a process accompanied by the release of a large amount of heat. Traditional heat dissipation methods such as natural heat dissipation and simple air cooling are severely insufficient when facing high-current fast charging or long-term charging conditions. When the internal temperature continues to rise and exceeds the temperature threshold for safe battery operation, thermal runaway can easily occur, leading to battery spontaneous combustion, which seriously threatens equipment safety and the safety of personnel and property.

[0003] Patent publication number CN219697319U discloses a charging protection box for an energy storage battery, including: an outer shell; and a water bladder disposed inside the outer shell. The water bladder includes an inner wall and an outer wall surrounding the inner wall. The inner wall of the water bladder can form a receiving space for accommodating the energy storage battery, so that the water bladder wraps around the circumferential outer side of the energy storage battery.

[0004] To address the safety concerns associated with in-home battery charging, existing technologies employ a water bladder with an inner wall that encloses the battery. This water bladder surrounds the battery's periphery, and when the temperature or pressure within the enclosure reaches a preset level, the inner wall of the water bladder ruptures. However, this approach still results in a situation where traditional heat dissipation methods cannot meet the significant heat generated during charging, leading to excessively high internal temperatures and potentially causing battery spontaneous combustion.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] 1. This utility model provides a simple lead-acid battery charging and energy storage box, which uses an air inlet, air inlet filter, heat-conducting plate, exhaust filter, fan blade, motor, vent, rain cover, temperature measuring instrument, and measuring probe. When the battery is charging, the heat generated during charging is transferred to the heat-conducting plate through a clamping device. Then, the motor drives the fan blade to rotate, expelling the heated gas inside the outer shell and reducing the internal pressure of the base. External air enters the base through the air inlet. As the air flows over the heat-conducting plate, the increased surface area allows more air to flow over the surface. The heated air absorbs heat and rises, drawing in new, cooler air. The system creates convection currents, dissipating heat into the surrounding environment, lowering the heat source temperature, and ensuring normal equipment operation. The fan blades accelerate airflow, thus increasing heat dissipation efficiency. The air inside the casing is filtered through the inlet and outlet filters to prevent dust accumulation from affecting heat dissipation. The internal temperature can be monitored using a temperature measuring instrument. When the temperature is not high, the motor is reversed, causing air to be blown into the device from the top, increasing the internal pressure and forcing the gas inside to be expelled through the inlet. The airflow blowing through the inlet filter cleans the filter, preventing dust accumulation on its surface from affecting heat dissipation. The blown-out dust is then discharged through the inlet.

[0019] 2. This utility model provides a simple lead-acid battery charging and storage box, which uses a charging compartment, charging port, clamping plate, telescopic plate, spring, limiting groove, outer shell, cabinet door, fixing buckle, and sealing plate. By aligning the battery with the opening of the charging compartment and inserting it into the charging compartment, the battery squeezes the telescopic plate, causing the telescopic plate to tilt, thereby moving the clamping plate to both sides and compressing the spring, thus clamping batteries of different sizes. Then, the battery is charged using the charging port. After charging is complete, the battery is removed, and the spring rebounds due to its elasticity. The telescopic plate can seal the opening of the charging compartment, thereby preventing dust from entering the charging compartment and affecting the charging efficiency. After inserting the battery, the cabinet door is closed, and then the fixing buckle is rotated to fix the cabinet door, thus sealing the device.

[0020] 3.

When the ground is wet, the connecting plate can also be fixed to the wall. Then, the device is fixed to the wall through the snap-fit ​​between the buckle and the slot, thereby keeping the device away from the ground and preventing the device from getting wet.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to embodiments:

[0028] Example 1

[0029] like Figure 1-5As shown, this utility model provides a simple lead-acid battery charging and energy storage box, including a base 11. A shell 21 is fixedly connected to the top of the base 11. An air inlet 31 is fixedly connected to the bottom of the inner wall of the shell 21. The bottom of the air inlet 31 slopes downwards from back to front. A clamping device 4 is fixedly connected inside the shell 21. A heat-conducting plate 33 is provided on the side of the clamping device 4. A vent 37 is fixedly connected to the top of the shell 21. Ventilation holes are distributed in a circumferential array on the surface of the vent 37. A rain shield 38 is fixedly connected to the top of the vent 37. The rain shield 38 is frustoconical in shape. A motor 36 is fixedly connected to the bottom of the rain shield 38. The output end is fixedly connected to a fan blade 35, which is located inside the vent 37. A temperature measuring instrument 61 is fixedly connected to the side of the housing 21, and a measuring probe 62 is fixedly connected to the side of the temperature measuring instrument 61. The measuring probe 62 penetrates the outer wall of the housing 21 and extends into the interior of the housing 21. The device also includes a protection device 2, a clamping device 4, and a fixing device 5. The protection device 2 is used to protect the internal structure of the device; the clamping device 4 is used to clamp and charge the battery to be charged; the fixing device 5 is used to fix the position of the device; and an air inlet filter 32 is fixedly connected to the top of the air inlet 31. The circular through-hole at the top of the housing 21... A fixed exhaust port filter 34 is connected. In this embodiment, when the battery is charging, the heat generated during charging is transferred to the heat-conducting plate 33 through the clamping device 4. Then, the motor 36 is started to drive the fan blade 35 to rotate. By expelling the heated gas inside the outer casing 21, the internal pressure of the base 11 is reduced, and external air enters the base 11 through the air inlet 31. When the air flows over the heat-conducting plate 33, the heat-conducting plate 33 can increase the heat dissipation surface area, allowing more air to flow over the surface. After absorbing heat, the air becomes hot and rises, bringing in new cool air and forming convection, thereby dissipating heat into the surrounding environment, reducing the temperature of the heat source, and maintaining... For the equipment to operate normally, the fan blades 35 can accelerate air circulation, thereby improving heat dissipation efficiency. The air inside the housing 21 can be filtered through the inlet filter 32 and the exhaust filter 34 to prevent dust accumulation inside the device from affecting heat dissipation. The internal temperature of the device can be viewed through the temperature measuring instrument 61. When the temperature is not high, the motor 36 is reversed, and air is blown into the device from the top, increasing the internal pressure and causing the gas inside the device to be discharged from the inlet 31. The air blowing through the inlet filter 32 can clean the inlet filter 32, preventing dust accumulation on the filter surface from affecting heat dissipation. The blown-out dust is discharged through the inlet 31.

[0031] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the protective device 2 further includes a cabinet door 22, which is hinged to both sides of the outer shell 21. A fixing buckle 23 is rotatably connected to the surface of the left cabinet door 22. A sealing plate 24 is fixedly connected inside the outer shell 21. A through hole is opened on the surface of the sealing plate 24. The clamping device 4 is inserted into the through hole on the surface of the sealing plate 24.

A clamping plate 43 is slidably connected inside the limiting groove 46. There are two clamping plates 43. One end of the springs 45 away from the side of the charging chamber 41 is fixedly connected to the surface of the corresponding clamping plate 43. A telescopic plate 44 is hinged to the front of the two clamping plates 43. The end of the telescopic plate 44 is hinged to the surface of the charging chamber 41.

[0032] In this embodiment, the device can be lifted by a forklift using the forklift slot 13 and moved to a suitable position. The device can then be fixed to the ground using the bolt holes on the surface of the fixing plate 12. When the ground is wet, the connecting plate 52 can be fixed to the wall, and the device can be fixed to the wall using the snap-fit ​​between the buckle 51 and the slot 53, thus keeping the device away from the ground and preventing it from getting damp. After installation, the battery is inserted into the charging compartment 41 by aligning it with the opening. The battery presses against the telescopic plate 44, causing the telescopic plate 44 to tilt, which in turn moves the clamping plate 43 to both sides, compressing the spring 45. This allows for clamping of batteries of different sizes. The battery is then charged using the charging port 42. After charging, the battery is removed, and the spring 45 rebounds due to its elasticity. The telescopic plate 44 can then seal the opening of the charging compartment 41. The charging chamber 41 is sealed to prevent dust from entering and affecting charging efficiency. After inserting the battery, the cabinet door 22 is closed, and the fixing buckle 23 is rotated to fix the cabinet door 22, thus sealing the device. By aligning the battery with the opening of the charging chamber 41 and inserting it into the charging chamber 41, the battery presses the telescopic plate 44, causing the telescopic plate 44 to tilt, thereby moving the clamping plate 43 to both sides and compressing the spring 45, thus clamping batteries of different sizes. Then, the battery is charged using the charging port 42. After charging is complete, the battery is removed, and the spring 45 rebounds due to its elasticity. The telescopic plate 44 can seal the opening of the charging chamber 41, thus preventing dust from entering and affecting charging efficiency. After inserting the battery, the cabinet door 22 is closed, and the fixing buckle 23 is rotated to fix the cabinet door 22, thus sealing the device.

[0033] Example 3

[0034] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a fixing plate 12 is fixedly connected to the left and right sides of the base 11, and bolt holes are opened on the surface of the fixing plate 12. Forklift slots 13 are opened on the left and right sides of the bottom of the base 11. The fixing device 5 includes a buckle 51, which is fixedly connected to the back of the outer shell 21.

The buckle 51 is inserted into the inside of the slot 53, and a fixing hole 54 is opened on the surface of the buckle 51.

[0035] In this embodiment, the device can be lifted by a forklift through the forklift slot 13 and moved to a suitable position. The device can then be fixed to the ground through the bolt holes on the surface of the fixing plate 12. When the ground is wet, the connecting plate 52 can also be fixed to the wall. The device can then be fixed to the wall through the snap-fit ​​between the buckle 51 and the slot 53, thereby keeping the device away from the ground and preventing it from getting damp.

[0036] The working principle of this simple lead-acid battery charging and energy storage box will be explained in detail below.

[0037] like Figure 1-5 As shown, during battery charging, the heat generated is transferred to the heat-conducting plate 33 via the clamping device 4. Then, the motor 36 is activated, driving the fan blades 35 to rotate. This reduces the internal pressure of the base 11 by expelling the heated gas from the outer casing 21. External air enters the base 11 through the air inlet 31. As the air flows over the heat-conducting plate 33, the increased surface area allows for greater airflow. The heated air absorbs heat and rises, drawing in cooler air and creating convection. This dissipates heat into the surrounding environment, lowering the heat source temperature and ensuring normal equipment operation. The fan blades 35 can accelerate air circulation, thereby improving heat dissipation efficiency. The air inside the housing 21 can be filtered through the inlet filter 32 and the exhaust filter 34 to prevent dust accumulation inside the device from affecting heat dissipation. The internal temperature of the device can be viewed through the temperature measuring instrument 61. When the temperature is not high, the motor 36 is reversed, and air is blown into the device from the top, increasing the internal pressure and causing the gas inside the device to be discharged from the inlet 31. The air blowing through the inlet filter 32 can clean the inlet filter 32, preventing dust accumulation on the filter surface from affecting heat dissipation. The blown dust is discharged through the inlet 31.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
