[0002] A new energy wind power station is a power plant that uses wind energy to drive wind turbines to drive generators to produce electricity. Wind energy is a renewable energy source. Using wind power to generate electricity is very environmentally friendly and pollution-free, and the wind energy reserves are huge. Therefore, the construction and commissioning of new energy wind power stations are gradually increasing. In the process of using wind power to generate electricity, due to the influence of external environmental factors such as different wind directions, uneven wind force, and ambient temperature, there is an imbalance in the supply and use of electricity in wind power generation. Therefore, in new energy wind power stations, the wind power generation system is usually equipped with a hybrid energy storage control device for the storage of electricity and balanced supply and use of electricity.

[0003] When some new energy hybrid energy storage device protection systems are in use, they usually do not have a good anti-collision protection function, which makes the hybrid energy storage control device easy to be damaged when it is hit by external force. In addition, when some hybrid energy storage control devices with anti-collision protection mechanisms are in use, the structure is relatively complex and the safety factor is low. It is not convenient to quickly disassemble and install the anti-collision protection mechanism, which brings inconvenience to the inspection and maintenance of the hybrid energy storage control device.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] See also Figure 1 and Figure 2 , the new energy hybrid energy storage device protection system provided by the utility model is now described. The new energy hybrid energy storage device protection system includes: a support platform 1, two protection piles 6, two protection covers 2, a cover plate 3 and a buffer sleeve 5. The support platform 1 is used to place the energy storage device. The two protection piles 6 are fixed on the support platform 1 and are located on both sides of the energy storage device. The two protection covers 2 are arranged opposite to each other and are respectively hinged on the two protection piles 6; the two protection covers 2 are swung upward to shield the energy storage device.

The buffer sleeve 5 is engaged with the inner side of the two protection covers 2; the buffer sleeve 5 is used to improve the ability of the protection cover 2 to resist external impact.

[0028] The beneficial effect of the new energy hybrid energy storage device protection system provided by the utility model is that: compared with the prior art, in the new energy hybrid energy storage device protection system of the utility model, an energy storage device is placed on the support platform 1, and protection piles 6 are fixed on both sides of the support platform 1, and two protection covers 2 are arranged oppositely and respectively hinged on the two protection piles 6. A buffer sleeve 5 is clamped on the inner side of the two protection covers 2, and a cover plate 3 is provided above the two protection covers 2, and the cover plate 3 is plugged and matched with the two protection covers 2.

[0029] In actual application, the two protective covers 2 are swung upward to shield the energy storage device, and by providing the buffer sleeve 5, on the one hand, the two protective covers 2 can be positioned in cooperation with the cover plate 3, and on the other hand, since the buffer sleeve 5 is an annular structure, the ability of the protective cover 2 to resist external impact can be improved to a certain extent. The overall structure of the present application is relatively simple, and at the same time, the safety factor is high, and the energy storage device can be well protected.

[0030] As the penetration rate of renewable energy power generation increases, the randomness and strong volatility of renewable energy power generation have brought great challenges to the stable operation of the power grid, and the power system has increasingly increased its requirements for the flexibility of regulating resources. The fluctuation of renewable energy requires traditional power sources to increase their output to provide power compensation, which will inevitably increase the number of start-stop and ramp-up times of the units and increase the overall operating costs of the system. At the same time, in the process of power market and power system dispatch, it is required that the power resources available for dispatch in the power grid can continuously and stably output and operate for a period of time. The large fluctuations in the output of renewable energy in a short period of time make the system dispatch operation face great difficulties.

[0031] With the rapid development and in-depth application of energy storage technology, a series of difficulties and challenges brought to the power grid by the high proportion of new energy grid connection have gradually found effective ways to alleviate them. As a high-quality and efficient regulation resource, energy storage has the characteristics of rapid absorption or release of electric energy. It can complete the time migration of power and energy through energy conversion, and realize two-way flexible regulation of the active power imbalance of the system. Most of the existing energy storage configurations for smoothing the fluctuations of new energy use single energy storage, which has certain limitations in power output and energy supply. The use of a hybrid energy storage system can make various types of single energy storage complement each other, while meeting the power and energy requirements of the system and extending the cycle life of the energy storage system.

[0032] In some embodiments of the new energy hybrid energy storage device protection system provided in this application, please refer to Figure 1 The top of the protection pile 6 is provided with a limit bar 7, which abuts against the inner side of the protection cover 2. The protection cover 2 is hinged on the protection pile 6, and the protection cover 2 itself has a certain structural size. Therefore, if the protection cover 2 is hinged on the top of the protection pile 6, if there is no other limit measure, the entire protection cover 2 cannot remain stable. When the protection cover 2 is subjected to external impact, it is also impossible to provide good protection for the internal energy storage device.

[0033] Based on the above reasons, a limit strip 7 is provided on the top of the protective pile 6. The limit strip 7 is located on the inner side of the protective cover 2. The position of the protective cover 2 can be limited by the limit strip 7, which improves the ability of the protective cover 2 to resist external impact to a certain extent.

[0034] In some embodiments of the new energy hybrid energy storage device protection system provided in this application, please refer to Figure 1The limit strip 7 is formed integrally with the protection pile 6. The protection pile 6 and the limit strip 7 are integrated concrete parts, and the support platform 1 can also be a concrete plane. In order to ensure the stability of the position of the protection pile 6 itself, a clearance hole can be opened on the support platform 1, and the protection pile 6 passes through the clearance hole and a positioning rod 10 is installed and fixed at the bottom to ensure its own structure and the ability to resist external impact.

[0035] The outer side surface of the limiting strip 7 is a plane, and a buffer pad is provided on the outer side surface of the limiting strip 7. The buffer pad is mainly used to buffer the impact of the protective cover 2 on the limiting strip 7 and ensure the effective transmission of force.

[0036] In some embodiments of the new energy hybrid energy storage device protection system provided in this application, please refer to Figure 1 , a plurality of plug rods are fixed on the cover plate 3, and the plug rods are plugged into the protective cover 2. The bottom edge of the protective cover 2 is hinged on the protective pile 6. At this time, the two protective covers 2 are arranged opposite to each other. If there is no limit of the external component, the protective cover 2 will swing downward. Based on the above reasons, the cover plate 3 is connected to the top edge of the two protective covers 2, and the two protective covers 2 are plugged into the cover plate 3, that is, with the help of the limit effect of the cover plate 3, the relative position of the two protective covers 2 can be guaranteed to be stable.

[0037] In an embodiment, a plurality of plug rods are fixed on the bottom surface of the cover plate 3 , and the plug rods can be plugged into and matched with corresponding positions on the top edge of the protective cover 2 . Only by the above arrangement can the reliable connection between the cover plate 3 and the protective cover 2 be ensured.

[0038] In some embodiments of the new energy hybrid energy storage device protection system provided in this application, please refer to Figure 1 The cover plate 3 is provided with a plurality of weight-reducing holes 4. In order to reduce the weight of the entire cover plate 3, a plurality of weight-reducing holes 4 are provided on the cover plate 3. By providing the weight-reducing holes 4, the pressure of the cover plate 3 on the protective cover 2 can be greatly reduced, and the cost is correspondingly reduced.

[0039] The cover plate 3 is the key to ensure the relative stability of the two protective covers 2. Based on the above reasons, the cover plate 3 itself needs to have a certain structural strength. In order to prevent the cover plate 3 from slipping off the protective cover 2, after the insertion rod is plugged into the protective cover 2, a nut can be threadedly connected at the bottom end of the insertion rod, and the nut can be pressed against the protective cover 2, thereby ensuring the reliable connection between the cover plate 3 and the protective cover 2.

[0040] In some embodiments of the new energy hybrid energy storage device protection system provided in this application, please refer to Figure 1 and Figure 2The bottom ends of the inspection door 8 are respectively hinged on the two protection piles 6. In the process of daily use, the inspection door 8 needs to be opened or closed frequently. It is for the above reasons that corresponding clearance holes need to be opened on the two protection covers 2. The inspection door 8 is hinged on the protection piles 6 and can block the clearance holes.

[0041] For further explanation, the top edge of the inspection door 8 is detachably connected to the two protective covers 2 by bolts. Because the two protective covers 2 are arranged opposite to each other and separated by a certain distance, the stability of the position between the two protective covers 2 is improved to a certain extent by installing and connecting the inspection door 8.

[0042] In some embodiments of the new energy hybrid energy storage device protection system provided in this application, please refer to Figure 1 and Figure 2 The inspection door 8 is plugged into the protective cover 2 and is made of transparent material. In order to facilitate effective observation of the energy storage device, the inspection door 8 in this application is made of transparent material and has a certain structural strength, so that the positions of the two protective covers 2 can be strengthened.

[0043] In some embodiments of the new energy hybrid energy storage device protection system provided in this application, please refer to Figure 1 and Figure 2 , a support ring 9 is fixed on the guard pile 6, and the guard cover 2 is hinged on the support ring 9. For further explanation, multiple support rings 9 are fixed along the length direction of the guard pile 6, and the guard cover 2 is hinged on multiple support rings 9. The support ring 9 itself is fixed on the guard pile 6, and finally the guard cover 2 is supported by multiple support rings 9, and the relative swing of the guard cover 2 is satisfied.

[0044] In some embodiments of the new energy hybrid energy storage device protection system provided in this application, please refer to Figure 1 , there are multiple support rings 9 on the protection pile 6, and a connecting shaft is passed through the inner side of the multiple support rings 9, and the protective cover 2 is hinged on the connecting shaft. For more detailed description, the multiple support rings 9 are coaxially arranged, and the connecting shaft is passed through the multiple support rings 9 on the same side, and the bottom side of the protective cover 2 is also provided with multiple through holes. In actual application, the through hole on the bottom side of the protective cover 2 is coaxially arranged with the support ring 9, and then the connecting shaft is inserted to achieve the installation of the protective cover 2.

[0045] In some embodiments of the new energy hybrid energy storage device protection system provided in this application, please refer to Figure 1 A positioning rod 10 is fixed in the protection pile 6, and the support ring 9 is fixed on the positioning rod 10. The positioning rod 10 can be pre-buried in the protection pile 6, and the support ring 9 can be directly welded to the top of the positioning rod 10.
