Description

Technical Field

[0001] This utility model relates to the field of energy storage grid-connected equipment technology, and specifically to a control device for energy storage grid-connected equipment. Background Technology

[0002] Energy storage grid-connected equipment is an intelligent power device that integrates a bidirectional inverter, grid-connected controller and energy management system. It is mainly used to realize bidirectional energy flow between the energy storage system and the power grid.

[0003] In the existing technology, with the rapid development of renewable energy, the importance of energy storage technology in the energy system is becoming increasingly prominent. As a key link connecting the energy storage system and the power grid, the performance of the control equipment of the energy storage grid-connected equipment directly affects the stable operation of the energy storage system and the safe access of the power grid. The energy storage grid-connected equipment is generally controlled by an electrical cabinet.

[0004] However, when electrical cabinets are used for a long time, the internal temperature of the cabinets rises due to the prolonged power supply to the internal equipment. Excessive temperature can easily damage and age the internal equipment, thus affecting energy storage and potentially posing safety hazards in severe cases.

[0005] Based on this, the present invention designs a control device for an energy storage grid-connected device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a control device for energy storage grid-connected equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A control device for an energy storage grid-connected device includes an electrical cabinet body and a heat exchanger body, and also includes a heat exchanger replacement component, a heat exchanger ejection component and a heat exchanger limiting component;

[0009] The heat exchanger body is slidably disposed on the inner wall surface of the mounting groove opened inside the electrical cabinet body;

[0010] The side surface of the electrical cabinet body is equipped with a heat exchanger replacement assembly that facilitates the replacement of the heat exchanger body from inside the electrical cabinet body.

[0011] The inner wall side surface of the mounting groove inside the electrical cabinet body is equipped with a heat exchanger ejection component that can push the heat exchanger body.

[0012] The lower surface of the heat exchanger body is equipped with a heat exchanger limiting component that can fix the heat exchanger body inside the electrical cabinet body for limiting its position.

[0013] The heat exchanger replacement assembly and the heat exchanger ejection assembly are located on both sides of the heat exchanger body, and the heat exchanger limiting assembly is located between the heat exchanger replacement assembly and the heat exchanger ejection assembly. The heat exchanger replacement assembly, the heat exchanger ejection assembly, and the heat exchanger limiting assembly are all connected to the heat exchanger body.

[0014] Furthermore, the heat exchanger ejection assembly includes a storage rod, a first spring, and a push plate. The storage rod is fixedly disposed on the inner wall side surface of the mounting groove opened inside the electrical cabinet body. The first spring is fixedly sleeved on the outer surface of the storage rod. The guide rod fixed on the back of the push plate is slidably engaged inside the storage rod. The end of the first spring is fixedly connected to the back surface of the push plate.

[0015] Furthermore, positioning blocks are fixed on the upper and lower surfaces of the mounting groove inside the electrical cabinet body, and positioning grooves are provided at both the upper and lower ends of the heat exchanger body. The positioning blocks are slidably engaged with the positioning grooves. A groove is provided in the middle of the upper and lower ends of the heat exchanger body, and a first storage groove is provided on the bottom surface of the inner wall of the groove.

[0016] Furthermore, the heat exchanger replacement assembly includes a door and a second spring. The door is rotatably disposed on the side surface of the electrical cabinet body and communicates with its interior. One end of the second spring is fixed to the back surface of the door, and the other end of the second spring is fixed to the inner surface of the electrical cabinet body.

[0017] Furthermore, the heat exchanger limiting assembly includes a third spring, a first telescopic block, a second telescopic block, a fourth spring, a support plate, a first fixing block, and a second fixing block. The third spring is fixedly disposed on the inner wall of the first storage groove, the first telescopic block is slidably disposed on the inner wall of the first storage groove, the second telescopic block is slidably disposed inside the first telescopic block, the fourth spring is fixedly disposed on the back surface of the second telescopic block, and the support plate, the first fixing block, and the second fixing block are fixedly disposed on the bottom surface of the mounting groove opened inside the electrical cabinet body. The first fixing block and the second fixing block are located between two sets of support plates.

[0018] Furthermore, a second storage groove is provided on the side surface of the first telescopic block, and the second telescopic block is slidably disposed on the inner wall of the second storage groove. The second telescopic block has two sets symmetrically distributed on both sides of the first telescopic block, and the fourth spring is fixed between the two sets of second telescopic blocks.

[0019] Furthermore, the first fixing block is closer to the push plate than the second fixing block, and the height of the first fixing block is greater than the height of the second fixing block.

[0020] Furthermore, the side surfaces of the first and second fixing blocks facing the door are curved, and the side surface of the first telescopic block facing the push plate is also curved.

[0021] Compared with the prior art, the advantages of this utility model are as follows:

[0022] 1. The heat exchanger body can cool down the temperature inside the electrical cabinet body caused by prolonged power supply, thus preventing the internal equipment from aging and being damaged due to excessively high temperature.

[0023] 2. When the heat exchanger body is installed in the electrical cabinet body, the first telescopic block is located between the first fixed block and the second fixed block. When the heat exchanger body needs cleaning after long-term use, the fan door is opened to expose the side surface of the heat exchanger body. Then, the heat exchanger body is pushed inward, causing the push plate to move inward. The inward movement of the push plate will compress the first spring. Because the height of the first fixed block is relatively large, the first telescopic block retracts a greater length when moving on the arc surface of the first fixed block, causing the lowest point of the second telescopic block to be above the support plate. At this time, the second telescopic block loses the obstruction and limitation of the support plate. Due to the elasticity of the fourth spring... The fourth spring will push the second telescopic block out of the second storage slot, so that the lower end of the second telescopic block is in contact with the upper end of the support plate. At this time, the support plate will limit the vertical movement of the first telescopic block through the second telescopic block. The first telescopic block is restricted from moving downward, so that the first telescopic block is kept above the second fixed block. The first telescopic block is no longer blocked by the second fixed block. Due to the elasticity of the first spring, the first spring reset will push the heat exchanger body outward through the push plate, so that part of the heat exchanger body moves to the outside of the electrical cabinet body, making it convenient for workers to pull out the heat exchanger body, thereby realizing the convenient replacement of the heat exchanger body.

[0024] 3. When it is necessary to install a heat exchanger inside the electrical cabinet, first manually press the second telescopic blocks on both sides of the first telescopic block to retract them into the second storage slot. At this time, the heat exchanger can be pushed into the electrical cabinet through the open door. At the same time, the upper end of the support plate will limit the second telescopic block, preventing it from moving out of the second storage slot. When the first telescopic block moves between the first fixed block and the second fixed block, the heat exchanger is installed inside the electrical cabinet. Because the second fixed block is relatively small, the first telescopic block can only retract upwards due to the pressure of the second fixed block. At this height, the second telescopic block is still limited by the upper end of the support plate. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] Example 1, please refer to the accompanying drawings in the specification. Figures 1-9 A control device for an energy storage grid-connected device includes an electrical cabinet body 1 and a heat exchanger body 3, and also includes a heat exchanger replacement component 2, a heat exchanger ejection component 4 and a heat exchanger limiting component 5. The heat exchanger body 3 is slidably disposed on the inner wall surface of the mounting groove opened inside the electrical cabinet body 1.

[0039] A heat exchanger replacement assembly 2 is installed on the side surface of the electrical cabinet body 1 to facilitate the replacement of the heat exchanger body 3 from inside the electrical cabinet body 1. A heat exchanger push-out assembly 4 is installed on the inner wall side surface of the mounting groove opened inside the electrical cabinet body 1 to push the heat exchanger body 3. A heat exchanger limiting assembly 5 is installed on the lower surface of the heat exchanger body 3 to fix the heat exchanger body 3 inside the electrical cabinet body 1 for limiting its position.

[0040] The heat exchanger replacement assembly 2 and the heat exchanger ejection assembly 4 are located on both sides of the heat exchanger body 3, respectively. The heat exchanger limiting assembly 5 is located between the heat exchanger replacement assembly 2 and the heat exchanger ejection assembly 4. The heat exchanger replacement assembly 2, the heat exchanger ejection assembly 4 and the heat exchanger limiting assembly 5 are all connected to the heat exchanger body 3.

[0041] Based on Embodiment 1, the heat exchanger ejection assembly 4 includes a storage rod 9, a first spring 10, and a push plate 11. The storage rod 9 is fixedly disposed on the inner wall side surface of the mounting groove opened inside the electrical cabinet body 1. The first spring 10 is fixedly sleeved on the outer surface of the storage rod 9. The guide rod fixed on the back of the push plate 11 is slidably locked inside the storage rod 9. The end of the first spring 10 is fixedly connected to the back surface of the push plate 11.

[0042] The upper and lower surfaces of the inner wall of the mounting groove inside the electrical cabinet body 1 are fixed with positioning blocks 6. The upper and lower ends of the heat exchanger body 3 are provided with positioning grooves 7. The positioning blocks 6 are attached to the positioning grooves 7 and are slidably engaged. The middle position of the upper and lower ends of the heat exchanger body 3 is provided with a groove 8. The bottom surface of the inner wall of the groove 8 is provided with a first storage groove 16.

[0043] The heat exchanger replacement assembly 2 includes a door 12 and a second spring 13. The door 12 is rotatably disposed on the side surface of the electrical cabinet body 1 and communicates with its interior opening. One end of the second spring 13 is fixed to the back surface of the door 12, and the other end of the second spring 13 is fixed to the inner surface of the electrical cabinet body 1.

[0044] The heat exchanger limiting assembly 5 includes a third spring 14, a first telescopic block 15, a second telescopic block 18, a fourth spring 19, a support plate 20, a first fixing block 21, and a second fixing block 22. The third spring 14 is fixedly disposed on the inner wall of the first storage groove 16. The first telescopic block 15 is slidably disposed on the inner wall of the first storage groove 16. The second telescopic block 18 is slidably disposed inside the first telescopic block 15. The fourth spring 19 is fixedly disposed on the back surface of the second telescopic block 18. The support plate 20, the first fixing block 21, and the second fixing block 22 are fixedly disposed on the bottom surface of the mounting groove opened inside the electrical cabinet body 1. The first fixing block 21 and the second fixing block 22 are located between the two sets of support plates 20.

[0045] The first telescopic block 15 has a second storage groove 17 on its side surface. The second telescopic block 18 is slidably disposed on the inner wall of the second storage groove 17. The second telescopic block 18 has two sets symmetrically distributed on both sides of the first telescopic block 15. The fourth spring 19 is fixed between the two sets of the second telescopic blocks 18.

[0046] The first fixing block 21 is closer to the push plate 11 than the second fixing block 22, and the height of the first fixing block 21 is greater than the height of the second fixing block 22.

[0047] The side surfaces of the first fixing block 21 and the second fixing block 22 facing the door 12 are curved, and the side surface of the first telescopic block 15 facing the push plate 11 is also curved.

[0048] In actual use, the heat exchanger body 3 can cool down the temperature inside the electrical cabinet body 1 caused by the equipment being powered on for a long time, thus preventing the internal equipment from aging and being damaged due to excessive temperature.

[0049] When the heat exchanger body 3 is installed in the electrical cabinet body 1, the first telescopic block 15 is located between the first fixed block 21 and the second fixed block 22. When the heat exchanger body 3 needs to be cleaned after long-term use, the fan door 12 is opened to expose the side surface of the heat exchanger body 3. Then, the heat exchanger body 3 is pushed inward, causing the push plate 11 to move inward. The inward movement of the push plate 11 will compress the first spring 10. Because the height of the first fixed block 21 is relatively large, the first telescopic block 15 retracts a greater length when moving on the arc surface of the first fixed block 21, causing the lowest end of the second telescopic block 18 to be above the support plate 20. At this time, the second telescopic block 18 loses the obstruction and limitation of the support plate 20. Due to the elasticity of the fourth spring 19, the first... The four springs 19 will push the second telescopic block 18 out of the second storage slot 17, so that the lower end of the second telescopic block 18 is in contact with the upper end of the support plate 20. At this time, the support plate 20 will limit the vertical movement of the first telescopic block 15 through the second telescopic block 18. The first telescopic block 15 is restricted from moving downward, so that the first telescopic block 15 is kept above the second fixed block 22. The first telescopic block 15 is no longer blocked by the second fixed block 22. Due to the elasticity of the first spring 10, the first spring 10 will push the heat exchanger body 3 outward through the push plate 11, so that a part of the heat exchanger body 3 moves to the outside of the electrical cabinet body 1, making it convenient for workers to pull out the heat exchanger body 3, thereby realizing the convenient replacement of the heat exchanger body 3.

[0050] When it is necessary to install the heat exchanger 3 into the electrical cabinet body 1, first manually press the second telescopic blocks 18 on both sides of the first telescopic block 15 to retract it into the second storage slot 17. At this time, the heat exchanger 3 can be pushed into the electrical cabinet body 1 through the open fan door 12. At the same time, the upper end of the support plate 20 will limit the second telescopic block 18, so that the second telescopic block 18 cannot move out of the second storage slot 17. When the first telescopic block 15 moves between the first fixed block 21 and the second fixed block 22, the heat exchanger 3 is just installed inside the electrical cabinet body 1. Since the second fixed block 22 is relatively small, the first telescopic block 15 is limited in its upward retraction height due to the compression of the second fixed block 22. At this height, the second telescopic block 18 is still limited by the upper end of the support plate 20.

[0051] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
