[0001] This invention relates to the field of energy storage converter technology, specifically to a power module for an energy storage converter and an energy storage converter. Background Technology

[0002] The current energy storage industry is basically in line with the product demand trends of previously mature industries such as wind power and photovoltaics, both of which tend towards high power density, low cost, and easy maintenance.

[0003] As the core component of energy storage converters, power modules should meet the requirements of high stability and high reliability.

[0004] To facilitate maintenance, existing energy storage converter power modules are usually installed in a modular fashion within the energy storage converter. However, compared to integrated installation, this method has the disadvantage of poor connection strength. Therefore, improving the robustness of modularly installed power modules is a problem that needs to be solved. Summary of the Invention

[0008] Preferably, a straight piston cylinder is fixedly connected to the upper surface of the pressure plate, and one of the limiting plates is slidably connected inside the straight piston cylinder, with the limiting plate fitting against the inner wall of the straight piston cylinder.

[0009] Preferably, a curved cylinder is fixedly connected to the lower surface of the partition, a curved rod is slidably connected inside the curved cylinder, a hole is provided on the partition to cooperate with the curved rod, and a spring is fixedly connected between the curved rod and the curved cylinder.

[0010] Preferably, a curved piston cylinder is fixedly connected inside the curved rod, and an air pipe is fixedly connected between the curved piston cylinder and the straight piston cylinder. A curved piston rod is slidably connected inside the curved piston cylinder, and a magnet plate is fixedly connected to the end of the curved piston rod. A wedge block is fixedly connected to the top of the magnet plate. Two insert rods are symmetrically slidably connected to the side wall of the curved rod, and the ends of the two insert rods are slidably connected to the wedge block. The magnet plate and the insert rods are magnetically attracted to each other. An insertion hole that mates with the insert rod is opened inside the curved cylinder.

[0011] Preferably, the upper surface of the partition is provided with a storage mechanism for storing the air tube. The storage mechanism includes two upright blocks, and sliders are slidably connected to the opposite surfaces of the two upright blocks. An installation rod is rotatably connected between the two sliders. A storage roller is fixedly connected to the middle of the installation rod. The air tube is wound around the storage roller. A second torsion spring is sleeved at both ends of the installation rod. The two ends of the two second torsion springs are fixedly connected to the slider and the storage roller, respectively.

[0012] Preferably, a rectangular plate is fixedly connected to the end of the bent rod, a protrusion is fixedly connected to the side of the rectangular plate, and a groove that mates with the protrusion is provided on the side of the module box.

[0013] Preferably, positioning plates are fixedly connected to both sides of the partition, and the positioning plates and the upright blocks together limit the position of the module box.

[0014] Preferably, the upper surface of the partition plate is rotatably connected to two rotating cylinders on both sides of the module box. Both rotating cylinders are rolledly connected to the side wall of the module box. A cylindrical rod is rotatably connected inside the rotating cylinder. A circular plate is fixedly connected to the top of the cylindrical rod. A third torsion spring is fixedly connected between the circular plate and the bottom wall of the rotating cylinder. A gear is fixedly connected to the upper surface of the circular plate. An arc-shaped rack that meshes with the gear is fixedly connected to the side wall of the rectangular plate.

[0015] An energy storage converter, wherein a power module is electrically connected inside the energy storage converter and the power module is installed in a module box.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The present invention achieves this by rotating the shaft when the pressure plate is lifted. At this time, the first torsion springs at both ends of the shaft are twisted and have potential energy, thereby causing the pressure plate to swing towards the partition, thus fixing the module box placed between the pressure plate and the partition.

[0018] 2. When the positioning rod of the present invention is inserted into the module box, the tension spring is in a stretched state. At this time, the distance between the limiting plate and the pressure plate is greater than the distance when the positioning rod is not in contact with the module box. As a result, the tension spring applies a pulling force to the limiting plate, so that the limiting plate squeezes the positioning rod, and the positioning rod can be stably inserted into the insertion hole on the module box, making the positioning of the module box more stable.

[0019] 3. After the rectangular plate moves, the protrusion on its side engages with the groove on the side of the module box. At this time, the module box is squeezed by the rectangular plate and further limited by the protrusion, which makes the installation of the module box more stable and avoids the module box from loosening due to vibration.

[0020] 4. In this invention, as the rectangular plate approaches the module box, the arc-shaped rack on the side of the rectangular plate can approach and mesh with the gear. The gear rotates, thereby driving the circular plate and cylindrical rod to rotate. At this time, the rotating cylinder is in contact with the module box, and the friction between the two makes it difficult for the rotating cylinder to rotate. Then, the third torsion spring is twisted, and the third torsion spring applies torque to the rotating cylinder, making the rotating cylinder tend to rotate. This increases the static friction between the rotating cylinder and the module box, making the module box not easily move towards the cabinet door, thus improving the stability of the module box installation.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Reference Figures 1-9 The present invention provides a technical solution: a power module for an energy storage converter, including an electrical cabinet 1 and a module box 13 for holding the power module. The electrical cabinet 1 is rotatably connected to a cabinet door 11. A partition 12 for receiving the module box 13 is fixedly connected inside the electrical cabinet 1. A rotating shaft 2 is rotatably connected inside the electrical cabinet 1. Two rings 21 are fixedly connected at both ends of the rotating shaft 2 inside the electrical cabinet 1. A first torsion spring 22 is fixedly connected between the rings 21 and the rotating shaft 2. A pressure plate 23 is fixedly connected to the side wall of the rotating shaft 2. The module box 13 is installed under the pressure plate 23.

[0034] When installing module box 13, open cabinet door 11, manually lift pressure plate 23, place module box 13 on top of partition 12, and make module box 13 below pressure plate 23. When pressure plate 23 is lifted, rotating shaft 2 rotates. At this time, the first torsion spring 22 at both ends of rotating shaft 2 is twisted and has potential energy, so that pressure plate 23 has a tendency to swing towards partition 12, thereby fixing module box 13 placed between pressure plate 23 and partition 12.

[0035] A positioning rod 24 is slidably connected to the pressure plate 23. A limiting plate 25 is fixedly connected to the top of the positioning rod 24. A tension spring 26 is sleeved on the positioning rod 24. The two ends of the tension spring 26 are fixedly connected to the limiting plate 25 and the pressure plate 23 respectively. An insertion hole that mates with the positioning rod 24 is provided on the module box 13.

[0036] After the module box 13 is pushed in until it contacts the inner wall of the electrical cabinet 1, the positioning rod 24 on the pressure plate 23 is just above the socket on the module box 13. At this time, the pressure plate 23 is released, and then the pressure plate 23 swings towards the module box 13, so that the positioning rod 24 on the pressure plate 23 is inserted into the socket on the module box 13. However, the depth of the socket is not sufficient to accommodate all parts of the positioning rod 24. That is, when the positioning rod 24 is not in contact with the module box 13, the tension spring 26 is in its shortest state. When the positioning rod 24 is inserted into the module box 13, the tension spring 26 is in a stretched state. At this time, the distance between the limiting plate 25 and the pressure plate 23 is greater than the distance when the positioning rod 24 is not in contact with the module box 13. Therefore, the tension spring 26 applies a pulling force to the limiting plate 25, so that the limiting plate 25 squeezes the positioning rod 24, and the positioning rod 24 can be stably inserted into the socket on the module box 13, making the positioning of the module box 13 more stable.

[0037] A straight piston cylinder 3 is fixedly connected to the upper surface of the pressure plate 23, and a limiting plate 25 is slidably connected inside the straight piston cylinder 3, and the limiting plate 25 is in contact with the inner wall of the straight piston cylinder 3.

[0038] When the pressure plate 23 presses down the module box 13, the distance between the limiting plate 25 and the pressure plate 23 is greater than when it is in the state. That is, at this time, the limiting plate 25 slides upward relative to the straight piston cylinder 3, and the limiting plate 25 is in contact with the inner wall of the straight piston cylinder 3. As a result, the air in the straight piston cylinder 3 above the limiting plate 25 is squeezed by the limiting plate 25.

[0039] A bent cylinder 32 is fixedly connected to the lower surface of the partition 12. A bent rod 33 is slidably connected inside the bent cylinder 32. A hole is opened on the partition 12 to cooperate with the bent rod 33. A spring 34 is fixedly connected between the bent rod 33 and the bent cylinder 32.

[0040] The spring 34 inside the bend cylinder 32 can apply elastic force to the bend rod 33, making the bend rod 33 tend to slide outside the bend cylinder 32. The hole on the partition plate 12 allows the bend rod 33 to pass through.

[0041] A bent piston cylinder 35 is fixedly connected inside the bent rod 33. An air pipe 31 is fixedly connected between the bent piston cylinder 35 and the straight piston cylinder 3. A bent piston rod 36 is slidably connected inside the bent piston cylinder 35. A magnet plate 38 is fixedly connected to the end of the bent piston rod 36. A wedge block 37 is fixedly connected to the top of the magnet plate 38. Two insert rods 39 are symmetrically slidably connected on the side wall of the bent rod 33. The ends of the two insert rods 39 are slidably connected to the wedge block 37. The magnet plate 38 and the insert rods 39 are magnetically attracted. An insertion hole that mates with the insert rods 39 is opened inside the bent cylinder 32.

[0042] After the air inside the straight piston cylinder 3 is compressed, it enters the curved piston cylinder 35 through the air pipe 31. Initially, the curved piston rod 36 is inside the curved piston cylinder 35. At this time, the widest part of the wedge block 37 contacts the ends of the two insert rods 39, causing the two insert rods 39 to extend a certain length from the side wall of the curved rod 33. At the same time, the insert rods 39 are inserted into the insertion holes inside the curved cylinder 32. Therefore, the compressed spring 34 cannot push the curved rod 33 out, and the curved rod 33 will not extend to the top of the partition plate 12, thus not causing inconvenience to the placement of the module box 13. When air is injected into the curved piston cylinder 35, the curved piston rod 36 bends towards the curved piston cylinder 35. As the piston cylinder 35 slides outward, the narrower part of the wedge block 37 gradually contacts the insertion rod 39. At the same time, the magnet plate 38 at the bottom of the wedge block 37 can approach the two insertion rods 39 and attract them, causing the two insertion rods 39 to move closer to each other. The ends of the two insertion rods 39 retract into the curved rod 33. At this point, the insertion rods 39 no longer insert into the insertion holes in the curved cylinder 32, so the release of the spring 34 is no longer obstructed. The spring 34 will then pop the curved rod 33 out. Since there is a certain friction between the curved rod 33 and the partition plate 12, the curved rod 33 will not pop out of the curved cylinder 32 instantly, thus preventing the equipment from being damaged by impact.

[0043] The upper surface of the partition 12 is provided with a storage mechanism for storing the air tube 31. The storage mechanism includes two upright blocks 4. Slider blocks 41 are slidably connected to the opposite surfaces of the two upright blocks 4. An installation rod 42 is rotatably connected between the two sliders 41. A storage roller 43 is fixedly connected to the middle of the installation rod 42. The air tube 31 is wound around the storage roller 43. A second torsion spring 44 is sleeved at both ends of the installation rod 42. The two ends of the two second torsion springs 44 are fixedly connected to the slider 41 and the storage roller 43, respectively.

[0044] When the bent rod 33 extends out of the bent cylinder 32, the air pipe 31 will be pulled, thus releasing the air pipe 31 from the receiving roller 43. At this time, the air pipe 31 pulls the receiving roller 43, and the sliders 41 at both ends of the receiving roller 43 slide down the vertical block 4. At the same time, the mounting rod 42 rotates, and the second torsion spring 44 between the mounting rod 42 and the slider 41 is twisted and has potential energy, thus ensuring that the receiving roller 43 has a receiving pulling force on the air pipe 31, thereby making the air pipe 31 taut and preventing the air pipe 31 from loosening and affecting the installation of the module box 13.

[0045] A rectangular plate 5 is fixedly connected to the end of the bent rod 33, and a protrusion 51 is fixedly connected to the side of the rectangular plate 5. A groove that mates with the protrusion 51 is opened on the side of the module box 13.

[0046] Because the speed at which the bent rod 33 pops out is reduced, the rectangular plate 5 at the end of the bent rod 33 will not impact the installed module box 13. After the rectangular plate 5 moves, the protrusion 51 on its side engages in the groove on the side of the module box 13. At this time, the module box 13 is squeezed by the rectangular plate 5 and further limited by the protrusion 51, which makes the installation of the module box 13 more stable and prevents the module box 13 from loosening due to vibration.

[0047] Positioning plates 14 are fixedly connected to both sides of the partition 12. The positioning plates 14 and the upright block 4 together limit the position of the module box 13.

[0048] The positioning plate 14 and the partition plate 12 restrict the left and right position of the module box 13 relative to the electrical cabinet 1 during installation. This ensures that when the module box 13 is placed on the partition plate 12 and pushed, the left and right position of the module box 13 will not shift, thereby ensuring that the positioning rod 24 can be accurately inserted into the socket on the module box 13.

[0049] The upper surface of the partition 12 is rotatably connected to two rotating cylinders 53 on both sides of the module box 13. Both rotating cylinders 53 are rotatably connected to the side wall of the module box 13. A cylindrical rod 54 is rotatably connected inside the rotating cylinder 53. A circular plate 55 is fixedly connected to the top of the cylindrical rod 54. A third torsion spring 56 is fixedly connected between the circular plate 55 and the bottom wall of the rotating cylinder 53. A gear 57 is fixedly connected to the upper surface of the circular plate 55. An arc-shaped rack 52 that meshes with the gear 57 is fixedly connected to the side wall of the rectangular plate 5.

[0050] The two rotating cylinders 53 also position the module box 13 for placement. Initially, the rotating cylinders 53 can rotate freely. After the module box 13 is placed, as the rectangular plate 5 moves closer to the module box 13, the arc-shaped rack 52 on the side of the rectangular plate 5 can approach the gear 57 and mesh with it. At this time, the gear 57 rotates, thereby driving the circular plate 55 and the cylindrical rod 54 to rotate. Since the rotating cylinder 53 is in contact with the module box 13 at this time, the friction between the two makes it difficult for the rotating cylinder 53 to rotate. Then, the third torsion spring 56 is twisted, and the third torsion spring 56 applies torque to the rotating cylinder 53, making the rotating cylinder 53 tend to rotate. Thus, the static friction between the rotating cylinder 53 and the module box 13 increases, so that the module box 13 will not easily move towards the cabinet door 11, improving the stability of the module box 13 installation.

[0051] Example 2

[0052] An energy storage converter has an internally connected power module installed in a module box 13.

[0053] By installing the power module inside the module box 13, the position of the power module is more stable, preventing the connecting wires between the power module and the equipment from loosening due to vibrations during later equipment operation, thus improving the stability of the power module installation.

[0054] Working principle: This is a power module for an energy storage converter. When in use, the cabinet door 11 is opened, the pressure plate 23 is manually lifted, and the module box 13 is placed on the upper part of the partition 12, so that the module box 13 is under the pressure plate 23. When the pressure plate 23 is lifted, the rotating shaft 2 rotates. At this time, the first torsion springs 22 at both ends of the rotating shaft 2 are twisted and have potential energy, so that the pressure plate 23 has a tendency to swing towards the partition 12, thereby fixing the module box 13 placed between the pressure plate 23 and the partition 12.

[0055] The positioning plate 14 and the partition plate 12 restrict the left and right position of the module box 13 relative to the electrical cabinet 1 during installation. This ensures that the left and right position of the module box 13 will not shift when it is placed on the partition plate 12 and pushed, thus guaranteeing that the positioning rod 24 can be accurately inserted into the socket on the module box 13. The two rotating cylinders 53 also position the module box 13 during placement. Initially, the rotating cylinders 53 can rotate freely. After the module box 13 is placed, as the rectangular plate 5 moves closer to the module box 13, the arc-shaped toothed rack 52 on the side of the rectangular plate 5 can... The cylinder 53 is close enough to mesh with gear 57. At this time, gear 57 rotates, which drives the circular plate 55 and the cylindrical rod 54 to rotate. Since the rotating cylinder 53 is in contact with the module box 13 at this time, the friction between the two makes it difficult for the rotating cylinder 53 to rotate. Then, the third torsion spring 56 is twisted, which applies torque to the rotating cylinder 53, making the rotating cylinder 53 tend to rotate. This increases the static friction between the rotating cylinder 53 and the module box 13, making the module box 13 less likely to move towards the cabinet door 11, thus improving the stability of the module box 13 installation.

[0056] After the module box 13 is pushed in until it contacts the inner wall of the electrical cabinet 1, the positioning rod 24 on the pressure plate 23 is just above the socket on the module box 13. Then, the pressure plate 23 is released, and the pressure plate 23 swings towards the module box 13, so that the positioning rod 24 on the pressure plate 23 is inserted into the socket on the module box 13. However, the depth of the socket is not enough to accommodate all parts of the positioning rod 24. That is, when the positioning rod 24 is not in contact with the module box 13, the tension spring 26 is in its shortest state. When the positioning rod 24 is inserted into the module box 13, the tension spring 26 is in a stretched state. At this time, the distance between the limiting plate 25 and the pressure plate 23 is greater than the distance when the positioning rod 24 is not in contact with the module box 13. Therefore, the tension spring 26 applies a pulling force to the limiting plate 25, so that the limiting plate 25 squeezes the positioning rod 24. Thus, the positioning rod 24 can be stably inserted into the socket on the module box 13, making the positioning of the module box 13 more stable.

[0057] When the pressure plate 23 presses down the module box 13, the distance between the limiting plate 25 and the pressure plate 23 is greater than when it is in the state. That is, at this time, the limiting plate 25 slides upward relative to the straight piston cylinder 3, and the limiting plate 25 is in contact with the inner wall of the straight piston cylinder 3. As a result, the air in the straight piston cylinder 3 above the limiting plate 25 is squeezed by the limiting plate 25.

[0058] After the air inside the straight piston cylinder 3 is compressed, it enters the curved piston cylinder 35 through the air pipe 31. Initially, the curved piston rod 36 is inside the curved piston cylinder 35. At this time, the widest part of the wedge block 37 contacts the ends of the two insert rods 39, causing the two insert rods 39 to extend a certain length from the side wall of the curved rod 33. At the same time, the insert rods 39 are inserted into the insertion holes inside the curved cylinder 32. Therefore, the compressed spring 34 cannot push the curved rod 33 out, and the curved rod 33 will not extend to the top of the partition plate 12, thus not causing inconvenience to the placement of the module box 13. When air is injected into the curved piston cylinder 35, the curved piston rod 36 bends towards the curved piston cylinder 35. As the piston cylinder 35 slides outward, the narrower part of the wedge block 37 gradually contacts the insertion rod 39. At the same time, the magnet plate 38 at the bottom of the wedge block 37 can approach the two insertion rods 39 and attract them. As a result, the two insertion rods 39 move closer to each other, and the ends of the two insertion rods 39 retract into the bent rod 33. Then, the insertion rods 39 no longer insert into the insertion holes in the bent cylinder 32, so the release of the spring 34 is no longer blocked. At this time, the spring 34 will pop out the bent rod 33. Since there is a certain friction between the bent rod 33 and the partition plate 12, the bent rod 33 will not pop out of the bent cylinder 32 instantly, thus preventing the equipment from being damaged by impact.

[0059] When the bent rod 33 extends from the bent cylinder 32, the air pipe 31 is pulled, thus releasing it from the collecting roller 43. At this time, the air pipe 31 pulls on the collecting roller 43, causing the sliders 41 at both ends of the collecting roller 43 to slide down the vertical block 4. Simultaneously, the mounting rod 42 rotates, causing the second torsion spring 44 between the mounting rod 42 and the slider 41 to twist and acquire potential energy. This ensures that the collecting roller 43 has a pulling force to collect the air pipe 31, thereby tautling the air pipe 31 and preventing... The loose air tube 31 affects the installation of the module box 13. Since the speed of the pop-out of the bent rod 33 is reduced, the rectangular plate 5 at the end of the bent rod 33 will not impact the installed module box 13. After the rectangular plate 5 moves, the protrusion 51 on its side engages in the groove on the side of the module box 13. At this time, the module box 13 is squeezed by the rectangular plate 5 and further limited by the protrusion 51, which makes the installation of the module box 13 more stable and avoids the module box 13 from loosening due to vibration.
