Description

Technical Field

[0001] This invention relates to the field of energy storage technology, and in particular to an energy storage device for a renewable energy generation module in a microgrid. Background Technology

[0002] Distributed energy resources (DER) include different types of equipment such as distributed power sources, controllable loads, and energy storage. DER not only offers flexible geographical deployment, effectively distributing power transmission demands across different regions, but also produces green and pollution-free energy, reducing the generation costs of traditional power distribution networks.

[0003] With the maturity of distributed energy technology, microgrid technology has begun to become widespread. A microgrid is a small-scale power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. The purpose of microgrids is to realize the flexible and efficient application of distributed power sources, solve the grid connection problem of a large number and diverse forms of distributed power sources, and develop and extend microgrids. This can fully promote the large-scale access of distributed power sources and renewable energy, realize highly reliable supply of multiple energy forms to loads, and is an effective way to realize active distribution networks, enabling the transition of traditional power grids to smart grids.

[0004] Microgrids primarily operate in two modes: grid-connected and islanded. Grid-connected microgrids are mainly used in large urban power grid systems, while islanded microgrids are mainly located on islands and in remote mountain villages. Compared to grid-connected microgrids, islanded microgrids can fully utilize local distributed energy resources (primarily renewable energy sources such as wind and solar power) and offer higher reliability.

[0005] In microgrid systems, energy storage devices are needed to store the electrical energy generated by renewable energy power generation modules in a timely manner. Taking wind power generation modules as an example, the energy storage devices used in wind power generation are generally installed on the inside of the wind power generation column. This not only saves installation space but also improves the stability of the wind power generation column to a certain extent. However, because the inner wall of the wind power generation column is curved, the installation process of the energy storage device is relatively complicated. Summary of the Invention

[0033] This invention proposes an energy storage device for renewable energy power generation modules in microgrids.

[0034] Please refer to the attached document. Figure 1 - Appendix Figure 4 In one embodiment of the energy storage device for a renewable energy generation module in a microgrid proposed in this invention, the energy storage device for the renewable energy generation module of this microgrid includes an energy storage device body (not labeled), a support assembly 120, and a connection assembly 130; the energy storage device body includes a housing 110, a battery (not shown), and a capacitor (not shown); the battery and the capacitor are disposed inside the housing 110; the number of support assemblies 120 is four; the support assembly 120 includes a connecting arm 140 and a support plate 170; the connecting arm 140 is used to connect to a wind turbine column via connecting bolts 150. The inner wall; the support plate 170 is connected to the connecting arm 140; there are 4 connecting assemblies 130; the connecting assembly 130 includes a support arm 180 and a connecting plate 190; the support arm 180 is located at the bottom of the outer shell 110; the support arm 180 is horizontally arranged; the connecting plate 190 is connected to the end of the support arm 180 away from the outer shell 110; the connecting plate 190 is used to connect to the support plate 170 by bolts; the support arms 180 of the 4 connecting assemblies 130 are centrally symmetrically distributed at the bottom of the outer shell 110, specifically, the support arms 180 of the 4 connecting assemblies 130 are in a cross shape.

[0035] The energy storage device for renewable energy generation modules in microgrids proposed in this invention can be installed on the inner wall of a wind turbine column more simply and conveniently. Specifically, when it is necessary to install this energy storage device on the inner wall of a wind turbine column, firstly, each connecting arm 140 is fixed to the inner wall of the wind turbine column by connecting bolts 150, and each connecting arm 140 is vertically set; then, the connecting plate 190 is connected to the bearing plate 170 by fastening bolts 340, and the outer shell 110 can be installed between each connecting arm 140. The installation steps are simpler and more convenient, and the connection between the outer shell 110 and the inner wall of the wind turbine column is more stable.

[0036] In addition, the support assembly 120 also includes a lifting plate 160 and fastening bolts 340; the connecting arm 140 includes a first wall 360 and a second wall 370 that are parallel to each other and vertically arranged; the first wall 360 is used to fit against the inner wall of the wind turbine column through the connecting bolts 150; the connecting arm 140 has an inner cavity 230; the inner cavity 230 is close to the second wall 370; the second wall 370 has a through groove 350 that passes through the inner cavity 230; the lifting plate 160 is vertically slidably embedded in the inner cavity 230; the bearing plate 170 is movably inserted through the through groove 350 and vertically connected to the lifting plate 160; the bearing plate 170 has a first threaded hole 530; the connecting plate 190 has a waist hole 520; the fastening bolts 340 are used to pass through the waist hole 520 and screw into the threaded hole 530 to fix the connecting plate 190 to the bearing plate 170.

[0037] Specifically, the above technical solution improves the structure and function of the support component 120, that is, the lifting plate 160 can move vertically relative to the connecting arm 140 to accommodate the slight swaying caused by the wind turbine column during normal operation.

[0038] Meanwhile, the length of the inner cavity 230 is consistent with the length of the connecting arm 140; the inner cavity 230 includes a third wall 240 and a fourth wall 250 arranged opposite to each other; the lifting plate 160 includes a first side 260 and a second side 270 that are parallel to each other; the first side 260 slides against the third wall 240; the second side 270 slides against the fourth wall 250; the support plate 170 is connected to the second side 270.

[0039] This configuration allows the lifting platform 160 to move vertically more stably, reducing horizontal swaying.

[0040] Due to the rotation of the wind turbine blades, the energy storage device may sway inside the wind turbine column, which not only affects the normal operation of the energy storage device, but may also cause the energy storage device to detach from the inner wall of the wind turbine column.

[0041] To this end, a first spring 280 is provided at the bottom of the inner cavity 230; the bottom end of the first spring 280 is connected to the bottom of the inner cavity 230; the top end of the first spring 280 is connected to the bottom of the lifting plate 160; the elastic force of the first spring 280 causes the lifting plate 160 to have an upward tendency. By providing the first spring 280, the lifting plate 160 can play a vertical buffering role, thereby reducing the swaying of the energy storage device inside the wind turbine column.

[0042] Specifically, the support assembly 120 also includes a baffle 290 and a second spring 320; the baffle 290 is vertically connected to the second wall 370; the second spring 320 is disposed between the baffle 290 and the support plate 170; the bottom end of the second spring 320 is connected to the upper surface of the baffle 290; the top end of the second spring 320 is connected to the support plate 170; the elastic force of the second spring 320 causes the support plate 170 to have an upward tendency; a first rib 310 is also disposed between the baffle 290 and the second wall 370; the first rib 310 is perpendicular to the baffle 290 and the second wall 370 respectively; the first rib 310 is located below the baffle 290.

[0043] By setting a second spring 320, the buffering and shock absorption capacity of the bearing plate 170 is further improved, thereby enhancing the shock absorption capacity of the entire energy storage device body. This counteracts the swaying of the energy storage device within the wind turbine column caused by the rotation of the wind turbine blades, ensuring the stability of the energy storage device.

[0044] In addition, as attached Figure 2 and attached Figure 4 As shown, the aforementioned support assembly 120 also includes a pressure plate 330; the pressure plate 330 is hinged to the second side 270; the pressure plate 330 is located above the support plate 170; the pressure plate 330 can rotate to be parallel to the support plate 170; the pressure plate 330 has a through hole 510; when the pressure plate 330 rotates to be parallel to the support plate 170, the distance between the pressure plate 330 and the support plate 170 is the thickness of the connecting plate 190, and the through hole 510 is directly opposite to the first threaded hole 530; the fastening bolt 340 is used to pass through the through hole 510 and the waist hole 520 in sequence, and is screwed into the first threaded hole 530 to fix the connecting plate 190 to the support plate 170. Through the above technical solution, the pressure plate 330 can press tightly against the connecting plate 190, thereby improving the connection stability between the outer shell 110 and the wind turbine column.

[0045] Meanwhile, the connecting assembly 130 also includes a rectangular sleeve 210; the support arm 180 includes a first plate 410 and a second plate 420 that are parallel to each other and opposite to each other; two support plates 430 are provided between the first plate 410 and the second plate 420, and the support plates 430 are perpendicular to the first plate 410 and the second plate 420 respectively; the first plate 410 and the second plate 420 are both horizontally arranged; the rectangular sleeve 210 is horizontally arranged at the bottom of the outer shell 110; the support arm 180 is slidably embedded in the rectangular sleeve 210; the connecting plate 190 is connected to the side of the support arm 180 that extends out of the rectangular sleeve 210; specifically, the connecting plate 190 is attached to the inner wall of the first plate 410, and the connecting plate 190 is connected to the support plate 430 near the connecting plate 190.

[0046] This configuration allows the support arm 180 to slide horizontally relative to the rectangular sleeve 210, thereby adjusting the distance between the connecting plate 190 and the outer casing 110 to accommodate wind turbine columns with different internal dimensions.

[0047] Furthermore, the rectangular sleeve 210 includes a fifth wall 380 and a sixth wall 390 that are opposite to each other and parallel to each other; both the fifth wall 380 and the sixth wall 390 are horizontally arranged; the first plate 410 is in sliding contact with the fifth wall 380; and the second plate 420 is in sliding contact with the sixth wall 390. The above technical solution improves the structure of the connecting assembly 130.

[0048] Meanwhile, the connecting assembly 130 also includes a lead screw 220 and a driving component; the rectangular sleeve 210 is provided with a first partition 450 and a second partition 460; the first partition 450 and the second partition 460 are located on the side of the rectangular sleeve 210 away from the connecting plate 190; the lead screw 220 rotatably passes through the first partition 450 and the second partition 460; the support plate 430 near the first partition 450 is provided with a second threaded hole (not shown), and the lead screw 220 is screwed into the second threaded hole; the lead screw 220 is horizontally arranged; the driving component is used to drive the lead screw 220 to rotate, so as to drive the support arm 180 to slide horizontally.

[0049] Specifically, the first partition 450 and the second partition 460 are parallel to each other, and both the first partition 450 and the second partition 460 are vertically arranged; a second rib 440 is provided at the connection between the connecting plate 190 and the support arm 180.

[0050] The above technical solution further improves the structure and function of the connecting component 130. When it is necessary to adjust the horizontal position of the support arm 180 relative to the rectangular sleeve 210, the drive component is activated to drive the lead screw 220 to rotate, thereby driving the support arm 180 to slide horizontally, thereby adjusting the distance between the connecting plate 190 and the outer shell 110 to accommodate wind turbine columns with different internal dimensions.

[0051] In addition, the aforementioned driving components include a rotating rod 490, a first bevel gear 470, and a second bevel gear 480; the rotating rod 490 rotatably passes through the lower wall of the rectangular sleeve 210; the rotating rod 490 is vertically arranged; the first bevel gear 470 is coaxially sleeved on the lead screw 220; the second bevel gear 480 is coaxially sleeved on one end of the rotating rod 490 that extends into the rectangular sleeve 210; the first bevel gear 470 and the second bevel gear 480 mesh; both the first bevel gear 470 and the second bevel gear 480 are located between the first partition plate 450 and the second partition plate 460; the bottom end of the rotating rod 490 extends out of the rectangular sleeve 210, and a cross groove (not shown) is provided at the bottom end of the rotating rod 490.

[0052] The above technical solution improves the structure and function of the drive component. When it is necessary to drive the lead screw 220 to rotate, an electric screwdriver is used to insert into the cross slot to drive the rotating rod 490 to rotate, thereby driving the lead screw 220 to rotate.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
