Description

Technical Field

[0001] This utility model belongs to the field of power energy storage technology, specifically relating to a lithium battery energy storage device for power distribution areas. Background Technology

[0002] The distribution network lithium battery energy storage device is an energy storage device specifically designed for distribution network scenarios. It uses lithium battery packs as the core energy storage carrier and integrates key components such as battery management system, energy storage converter, and energy management system. Through the storage and release of electrical energy, it can dynamically adjust and optimize the operating status of the distribution network.

[0003] However, when lithium battery energy storage devices are in use, they are usually placed inside a cabinet and rely on ventilation devices for ventilation and heat dissipation. However, if the ambient air humidity is high during ventilation, the humid air entering the cabinet can accelerate the aging process of the internal batteries, leading to an increase in equipment failure rate. Since the existing devices lack the function of dehumidifying the circulating air, they cannot improve the humid environment inside the cabinet, thus significantly shortening the overall service life of the equipment.

[0004] To address the aforementioned issues, this application proposes a lithium battery energy storage device for power distribution areas. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a lithium battery energy storage device for power distribution areas, which has the characteristic of reducing battery aging and failure caused by moisture, thereby extending the service life of the lithium battery energy storage device for power distribution areas.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery energy storage device for a transformer substation, comprising a housing, an air inlet frame fixedly connected to the front of the housing, a placement shell fixedly connected to the front of the air inlet frame, a baffle slidably connected to the inner wall of the air inlet frame, an electric push rod provided on the front of the air inlet frame, a drying cotton block provided inside the placement shell, a filter air inlet pipe fixedly connected to the upper surface of the placement shell, an energy storage device fixedly connected to the inner bottom wall of the housing, a humidity sensor provided inside the housing, a controller provided on the front of the housing, an air duct fixedly connected to the right side of the housing, and a fan provided inside the air duct.

[0007] As a preferred embodiment of this utility model, the left side of the box is movably hinged with two opening and closing doors, and each opening and closing door is fixedly connected to an assist plate on its left side.

[0008] As a preferred embodiment of this utility model, a mounting plate is fixedly connected to the back of the controller, and the back of the mounting plate is fixedly connected to the front of the housing.

[0009] As a preferred embodiment of this utility model, a fixing ring is fixedly connected to the bottom end of the humidity sensor, and the fixing ring is fixedly connected to the inner bottom wall of the box.

[0010] As a preferred embodiment of this utility model, the front of the housing is hinged to a connecting door, and the front of the connecting door is fixedly connected to a handle.

[0011] As a preferred embodiment of this utility model, a fixing block is fixedly connected to the left end of the electric push rod, and the back of the fixing block is fixedly connected to the front of the air inlet frame.

[0012] As a preferred embodiment of this utility model, the telescopic end of the electric push rod is fixedly connected to a connecting frame, and the back of the connecting frame is fixedly connected to the front of the baffle.

[0013] As a preferred embodiment of this utility model, a fixing seat is fixedly connected to the back of the fan, and the back of the fixing seat is fixedly connected to the inner wall of the air guide pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a linkage structure between the drying cotton block and the humidity sensor, when the humidity inside the chamber exceeds the threshold, the controller can adjust the electric push rod to open the baffle, allowing air to enter the chamber after being filtered and dehumidified by the drying cotton block. This effectively reduces the humidity of the circulating air, reducing the aging speed and failure rate of the battery caused by the humid environment. The fan and the electric push rod work together to form an adjustable ventilation path, maintaining natural ventilation when the humidity is normal and automatically switching to dehumidification ventilation mode when the humidity is high. Compared with the traditional fixed ventilation design, this significantly improves the adaptability to humid environments, thereby extending the overall service life of the equipment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please see Figure 1-7 The present invention provides the following technical solution: a lithium battery energy storage device for a transformer substation, comprising a housing 1, an air inlet frame 2 fixedly connected to the front of the housing 1, a placement shell 9 fixedly connected to the front of the air inlet frame 2, a baffle 18 slidably connected to the inner wall of the air inlet frame 2, an electric push rod 17 provided on the front of the air inlet frame 2, a drying cotton block 14 provided inside the placement shell 9, a filter air inlet pipe 15 fixedly connected to the upper surface of the placement shell 9, an energy storage device 6 fixedly connected to the inner bottom wall of the housing 1, a humidity sensor 10 provided inside the housing 1, a controller 8 provided on the front of the housing 1, an air duct 5 fixedly connected to the right side of the housing 1, and a fan 21 provided inside the air duct 5.

[0026] In this embodiment, the drying cotton block 14 is filled with a highly efficient desiccant. This design can fully absorb the moisture in the humid air entering the box 1, greatly reduce the humidity of the circulating air, provide a dry environment for the energy storage device 6 inside the box, reduce equipment failures caused by moisture, and help extend the service life of the device.

[0027] Specifically, the left side of the housing 1 has two hinged doors 3, and each door 3 has a fixed auxiliary plate 4 on its left side. In this embodiment, the hinged doors 3 design allows the housing 1 to be opened easily, facilitating the inspection and maintenance of the internal energy storage device 6. The auxiliary plate 4 provides a force point for opening and closing the doors 3, effectively reducing the difficulty of operation and improving the efficiency of maintenance work.

[0028] Specifically, a mounting plate 7 is fixedly connected to the back of the controller 8. The back of the mounting plate 7 is fixedly connected to the front of the housing 1. In this embodiment, the controller 8 can be fixed by the mounting plate 7. At the same time, the controller 8 adopts a programmable logic controller (PLC), which is a digital computing and operating electronic system designed for industrial environments. It stores instructions through a programmable memory to realize the automated control of machinery or production processes.

[0029] Specifically, a fixing ring 11 is fixedly connected to the bottom of the humidity sensor 10. The fixing ring 11 is fixedly connected to the inner bottom wall of the housing 1. In this embodiment, the humidity sensor 10 can be fixed by the fixing ring 11. At the same time, the humidity sensor 10 is a device used to measure the water vapor content in the environment. It converts the humidity in the air into a measurable electrical signal through physical or chemical principles, thereby realizing the accurate detection and monitoring of the ambient humidity.

[0030] Specifically, the front of the housing 9 is hinged to a connecting door 12, and the front of the connecting door 12 is fixedly connected to a handle 13. In this embodiment, the housing 9 can be quickly opened through the hinged connecting door 12, which facilitates the replacement or maintenance of the internal drying cotton block 14. The handle 13 makes it easy for the operator to grip and exert force, making the opening and closing of the connecting door 12 more effortless and convenient, and ensuring the timely maintenance of the dehumidification component.

[0031] Specifically, a fixing block 16 is fixedly connected to the left end of the electric push rod 17. The back of the fixing block 16 is fixedly connected to the front of the air inlet frame 2. In this embodiment, the electric push rod 17 is stably installed on the air inlet frame 2 by the fixing block 16, which can effectively disperse the force generated by the electric push rod 17 when it is working, avoid its position shift due to vibration or uneven force, and ensure that the electric push rod 17 can stably drive the baffle 18 to perform opening and closing actions.

[0032] Specifically, the telescopic end of the electric push rod 17 is fixedly connected to a connecting frame 19, and the back of the connecting frame 19 is fixedly connected to the front of the baffle 18. In this embodiment, the telescopic end of the electric push rod 17 is connected to the baffle 18 through the connecting frame 19, which increases the contact area between the two, so that the driving force of the electric push rod 17 can be transmitted to the baffle 18 more evenly, ensuring that the baffle 18 runs smoothly during the opening and closing process and accurately controls the opening and closing degree of the air intake channel.

[0033] Specifically, a fixing seat 20 is fixedly connected to the back of the fan 21. The back of the fixing seat 20 is fixedly connected to the inner wall of the air duct 5. In this embodiment, the fan 21 is firmly fixed in the air duct 5 by the fixing seat 20, which can effectively buffer the vibration generated by the fan 21 when it is working, reduce the loosening of parts or noise caused by vibration, and at the same time ensure that the installation position of the fan 21 in the air duct 5 is stable, thus ensuring ventilation efficiency and equipment operation stability.

[0034] The working principle and usage process of this utility model are as follows: First, check whether the connections of each component of the device are secure, ensuring that the drying cotton block 14 is in an effective state. Close the connecting door 12 of the housing 9 using the handle 13, and then close the opening and closing door 3 of the box 1 with the help of the assist plate 4. This completes the initial state check and preparation of the equipment. After starting the equipment, the humidity sensor 10 monitors the humidity inside the box 1 in real time and transmits the data to the controller 8. The controller 8 determines whether dehumidification is needed based on a preset threshold. When the humidity exceeds the standard, the electric push rod 17 controls the baffle 18 to slide within the air inlet frame 2 via the connecting frame 19, opening the air inlet channel. Simultaneously, the fan 21 in the air duct 5 is started, and external air enters through the filtered air inlet duct 1. 5. After entering the placement shell 9 and being moistened by the drying cotton block 14, the air enters the box 1 through the air inlet frame 2, achieving dehumidification and ventilation, and preventing humid air from affecting the energy storage device 6. When the humidity drops to the normal range, the controller 8 drives the electric push rod 17 to reset, causing the baffle 18 to close the air inlet channel, the fan 21 to stop working, and switch to natural ventilation mode to reduce energy consumption. During routine maintenance, if it is necessary to inspect the energy storage device 6, it can be operated by opening the opening and closing door 3 through the auxiliary plate 4. When the drying cotton block 14 is saturated with moisture, it can be replaced by opening the connecting door 12 through the handle 13 to ensure that the dehumidification function is continuously effective. The whole process realizes dynamic control of the operating environment through intelligent linkage, ensuring stable operation of the equipment and extending its service life.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
