However, due to the characteristics of energy storage power stations, such as the large amount of heat generated during their operation, the safety and stability of their operation are becoming increasingly prominent. The traditional monitoring device of energy storage power stations is simple in design and single in function, which makes it difficult to meet the complex and changing operating environment and safety requirements.

[0003] In order to improve the stability and safety of energy storage power stations, existing documents disclose a protective device for wind turbine energy storage devices, which includes a protective shell having a rectangular structure and a sealing cover arranged on the top of the protective shell, a moisture-proof bottom plate fixedly connected to the bottom of the protective shell, and a heat dissipation frame connected to the outside of the protective shell; a fixed shell having a rectangular structure and a heat dissipation bellows arranged on the outside of the fixed shell, a heat dissipation pipe connected to the side of the heat dissipation bellows close to the fixed shell; a partition device, which is used to partition the storage space in the protective shell, and the partition device includes a partition plate and a movable plate, and the storage space in the protective shell is partitioned by the partition plate and the movable plate; and a temperature control device, which dissipates heat and cools the inside of the protective shell through the temperature control device.

[0004] Although existing literature provides temperature control protection for energy storage devices, even under temperature control conditions, when an abnormality occurs in the working state of the energy storage device, the abnormality of its working state cannot be discovered in time.

[0018] Furthermore, a groove is provided on a side of the substrate away from the receiving cavity, and the heat dissipation fan is located between the grooves of the two substrates.

[0029] Figure 2 It is a front view of the protective shell in the first embodiment of the safety and stability device for energy storage power station of the utility model. DETAILED DESCRIPTION

[0030] The following is further explained in detail through specific implementation methods.

[0031] The reference numerals in the drawings of the specification include: outer shell 1, energy storage unit 2, detection board 3, groove 4, protective shell 5, substrate 31, heat dissipation hole 32, mounting hole 33, through hole 51, heat dissipation fan 6, heat dissipation slot 7.

[0032] Embodiment 1

[0033] Safety and stability devices for energy storage power stations, such as Figure 1As shown: it includes an outer shell 1, which is in a rectangular shape. A storage cavity for accommodating an energy storage unit 2 is opened in the outer shell 1. The storage cavity is in a rectangular shape. The energy storage unit 2 is a battery responsible for storing electrical energy. As for the type of battery, it can be any one of a lead-acid battery (Lead Acid), a nickel-cadmium battery (Ni-Cd), a nickel-metal hydride battery (Ni-MH) and a lithium battery (Li).

[0034] A detection board 3 for sealing the storage cavity is installed on the top of the outer shell 1 by screws. The edge of the detection board 3 extends out of the outer wall of the outer shell 1 by a preset length, and the preset length is 1.5-3cm. The detection board 3 includes at least two substrates 31 spliced ​​together. In this embodiment, two substrates 31 are taken as an example. The substrates 31 are made of glass. The substrates 31 are spliced ​​together to form a whole by bonding glue, and the material of the bonding glue can be UV glue.

[0035] A plurality of sensors for detecting the working state of the energy storage unit 2 are installed on the side of the detection board 3 facing the storage cavity. The sensors may be air pressure sensors, temperature sensors, smoke sensors, etc. A plurality of installation areas for setting different sensors are provided on the side of the substrate 31 facing the storage cavity. The installation areas are distributed in a rectangular array, such as the installation areas are arranged in four rows and two columns on each substrate 31, and the installation areas are independent of each other. The installation areas are dispersedly arranged on the substrate 31, which can ensure that the sensor units can evenly cover the key parts of the energy storage unit 2. By installing sensors at different positions, the working state and external environment of the energy storage unit 2 can be more comprehensively monitored. The shape of the installation area may be rectangular, circular or other shapes suitable for sensor installation. The specific shape depends on the shape and size of the sensor. In one embodiment, the shape of the installation area is square, with a size of 4m*4m, and the installation area includes a plurality of installation holes 33, which are arranged in a rectangular array, such as six installation holes 33 in each installation area, arranged in an array of two rows and six columns, thereby obtaining a corresponding square area.

[0036] The detection board 3 is provided with a plurality of heat dissipation holes 32 . No heat dissipation holes 32 are provided at the portion where the detection board 3 extends out of the outer shell 1 . A heat dissipation fan 6 is installed on the side of the detection board 3 away from the storage cavity. The diameter of the installation hole 33 is larger than the diameter of the heat dissipation hole 32 .

[0037] A protective shell 5 is installed on the top of the detection board 3, and the protective shell 5 is snapped on the detection board 3. The protective shell 5 is provided with several through holes 51 for ventilation, and the through holes 51 can be set to two or four. A heat dissipation groove 7 is provided on the side of the protective shell 5 facing the substrate 31, and the heat dissipation groove 7 is aligned with the groove 4 on the substrate 31. A groove 4 is provided on the side of the substrate 31 away from the storage cavity, and the heat dissipation fan 6 is located between the grooves 4 of the two substrates 31. There is an inclined section between the side wall and the bottom wall of the heat dissipation groove 7, forming a concave space. The concave design can provide a larger space for the heat dissipation fan 6 to ensure its normal operation and promote air circulation. The through hole 51 is located at the place where the inclined section contacts the bottom wall. The position of the through hole 51 can effectively guide the hot air generated by the heat dissipation fan 6 to be discharged in time, avoid the accumulation of hot air inside the protective shell 5, thereby improving the heat dissipation efficiency. The through hole 51 is not set in the center, which can prevent the hot air from forming a vortex in the shell before being discharged, affecting the heat dissipation effect.

[0038] The energy storage unit 2 is placed in the storage cavity of the outer shell 1, and the detection board 3 is installed on the top of the outer shell 1, and the storage cavity is completely sealed, which can protect the energy storage unit 2 from the influence of the external environment. The design of the detection board 3 is composed of at least two spliced ​​first substrates 31, and this structure can be easily installed, maintained and expanded as needed. The surface of the substrate 31 constituting the detection board 3 is provided with heat dissipation holes 32, which can effectively dissipate the heat generated when the detection board 3 is working, ensuring its stable operation. In addition, the surface of the substrate 31 is also divided into multiple installation areas, which are installed with sensors for monitoring and collecting various data. It is important that different sensors are installed in different positions to achieve comprehensive detection of the working state and external environment of the energy storage unit 2. The detection of the working state of the energy storage unit 2 by the outer shell 1 outside the energy storage unit 2 and the sensor prevents interference from the external environment, and ensures that the abnormality of the energy storage unit 2 is detected in time, starting from the external environment and the working state of the energy storage unit 2, to ensure the safe and stable operation of the energy storage unit 2.

[0039] Embodiment 2

[0040] The safety and stability device for energy storage power stations is different from the first embodiment in that a circuit unit for electrically connecting the sensor to transmit a signal is provided on the side of the substrate 31 facing the storage cavity. The circuit unit is prepared by existing etching, exposure, development and other processes. The circuit unit also directly adopts the existing circuit, which will not be repeated here. The signal transmitted by the circuit unit is transmitted to the subsequent processor unit for processing. After receiving these signals, the processor unit will perform real-time analysis and make corresponding judgments and processing according to the pre-stored existing algorithms. For example, if the temperature sensor detects that the temperature is too high, the processor unit may start the cooling fan 6 to lower the temperature, thereby ensuring the safe operation of the energy storage unit 2. For the specific model of the processor unit, Intel Core i3 / i5 / i7 / i9 can be selected. Through the setting of the circuit unit, data can be transmitted in time for subsequent analysis.

[0041] Embodiment 3

[0042] The safety and stability device for energy storage power stations differs from the first embodiment in that the diameter of the heat dissipation holes 32 within the circumferential setting range of the heat dissipation fan 6 is larger than the diameter of the heat dissipation holes 32 outside the setting range, the setting range is a range of 10 cm radiating outward from the end edge of the heat dissipation fan 6, and the heat dissipation holes 32 within the circumferential setting range of the heat dissipation fan 6 are tilted, and the heat dissipation holes 32 are tilted toward the side away from the heat dissipation fan 6, and the angle between the center of the tilted heat dissipation hole and the detection plate is 60°.

[0043] When the energy storage unit 2 is working abnormally, the diffusion of the generated gas or odor will take a certain period of time. The large size of the energy storage unit 2 makes the storage cavity have a certain height, and the sensor is located at the top of the storage cavity and cannot detect the corresponding signal in time. Therefore, in the third embodiment, the heat dissipation holes 32 within a certain range around the heat dissipation fan 6 are tilted to increase the flow of airflow in the storage cavity and change the direction of the airflow. This can stir the air in the storage cavity a little, so that the airflow when the energy storage unit 2 is abnormal can be quickly detected by the sensor, thereby improving the detection speed.

[0044] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
