Description

Technical Field

[0001] This invention belongs to the field of flywheel energy storage units, and in particular relates to a sealing and locking mechanism for flywheel energy storage units. Background Technology

[0002] The flywheel energy storage unit consists of a flywheel body, shaft, upper bearing, lower bearing, upper cover, and lower housing. To prevent damage to the bearings caused by impact loads during the movement of the flywheel energy storage unit, the flywheel motor shaft system must be locked. This is usually achieved by supporting both sides of the flywheel body to support the entire shaft. However, during the installation of the flywheel energy storage unit, the flywheel body needs to be locked using a locking device before connecting the upper cover to the lower housing. After the flywheel energy storage unit is moved to the work area, the upper cover is opened, the locking assembly is removed, and the cover is fixed to the lower housing to restore the seal. This operation is cumbersome. Summary of the Invention

[0003] In view of this, the present invention aims to provide a sealing and locking mechanism for flywheel energy storage units, in order to solve the technical problem that during the installation of flywheel energy storage units, it is necessary to lock the flywheel body with a locking device before connecting the upper cover to the lower housing, and then transfer the flywheel energy storage unit to the work area before opening the upper cover, taking out the locking component, fixing the cover to the lower housing, and restoring the seal, which is a cumbersome operation.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A sealing and locking mechanism for a flywheel energy storage unit includes a lower housing and an upper cover. A shaft is rotatably disposed between the lower housing and the upper cover. The lower housing has a first chamber inside. A flywheel body is fixedly sleeved on the surface of the shaft, and the flywheel body is located in the first chamber. The mechanism also includes multiple snap-fit ​​components, multiple clamping components, and multiple locking components. The multiple snap-fit ​​components are disposed at the joint between the upper cover and the lower housing, and are used to snap the outer sides of the upper cover and the lower housing. The multiple clamping components are located inside the first chamber, and are used to clamp and support the flywheel body. The multiple locking components are all located inside the first chamber, and are used to lock the upper cover body at the port of the lower housing. During the clamping process of the clamping components clamping the flywheel body, the locking components are linked to tighten the upper cover body.

[0006] Furthermore, each of the multiple snap-fit ​​components includes a snap-fit ​​base and an elastic buckle. The multiple snap-fit ​​bases are fixedly connected to the outer surface of the lower housing. The top of the snap-fit ​​base has a snap-fit ​​opening. The multiple elastic buckles are fixedly connected to the surface of the upper cover. The multiple elastic buckles pass through the multiple snap-fit ​​openings and snap onto the snap-fit ​​base.

[0007] Furthermore, each of the multiple clamping components includes a clamping seat, a threaded sleeve, and four jaws. The multiple clamping seats are fixedly connected to the inner wall of the first chamber. Each clamping seat corresponds to one of the multiple snap-fit ​​seats. Each clamping seat has an adjustment cavity. An upper adjustment plate and a lower adjustment plate are slidably arranged on both sides of the inner wall of the adjustment cavity. Sloping grooves are formed on the surfaces of both the upper and lower adjustment plates, and these grooves are symmetrically arranged within the adjustment cavity. Guide pins are provided inside each of the four sloping grooves. A push plate is fixedly connected between the four guide pins. A threaded rod is rotatably connected to the surface of the push plate. The threaded sleeve is fixedly connected to the inner wall of the snap-fit ​​seat. The threaded rod passes sequentially through the clamping seat, the lower housing, and the snap-fit ​​seat. The threaded rod is threadedly connected to the threaded sleeve. The four jaws are respectively positioned on the upper and lower adjustment plates.

[0008] Furthermore, the gripper includes an L-shaped connecting frame, which includes a vertical section and a horizontal section. The horizontal section located at the upper adjusting plate is slidably connected to the side wall of the upper adjusting plate, and the vertical section located at the lower adjusting plate is slidably connected to the side wall of the lower adjusting plate. Support springs are fixedly connected between the vertical sections at different positions and the ends of the upper and lower adjusting plates, respectively. A release clamping assembly is provided between the bottom end of the upper adjusting plate and the top end of the lower adjusting plate and the corresponding horizontal section, respectively. A clamping roller is provided at the end of the vertical section.

[0009] Furthermore, the release clamping assembly includes a push port and a clearance slot. The push port passes through a threaded rod and a push plate in sequence. An adjusting rod is slidably inserted into the push port. One end of the adjusting rod is located in the snap-fit ​​seat, and the other end is located in the clamping seat. A moving plate is fixedly connected to the end of the adjusting rod located in the clamping seat. Two symmetrically arranged bosses are fixedly connected to both sides of the moving plate. Each boss includes two inclined surfaces and a supporting surface. The clearance slot is opened on the connecting frame and is located at the connection between the vertical section and the horizontal section. The supporting surface of the boss is in contact with the surface of the horizontal section.

[0010] Furthermore, a threaded pin is fixedly connected to the end of the clamping roller, and the threaded pin is threadedly connected to the end of the vertical section.

[0011] Furthermore, each of the locking components includes two first connecting slots, which are located at the ends of two upper adjusting plates within the adjusting cavity. A mounting plate is slidably connected to each of the two first connecting slots, and a mounting groove is provided on the mounting plate. A return spring is fixedly connected between the mounting plate and the inner wall of the first connecting slot. A mounting body is inserted into both of the two first mounting slots. The top end of the mounting body is fixedly connected to the bottom surface of the upper cover, and mounting ends are fixedly connected to both sides of the bottom end of the mounting body. A guide surface is provided at the end of each mounting end.

[0012] Furthermore, multiple guide channels are fixedly connected to the inner wall of the lower housing. The top opening edge of the guide channel is chamfered. Multiple hangers pass through the multiple guide channels respectively. Both sides of the guide channel are provided with clearance channels for the hanger end to pass through.

[0013] Furthermore, an L-shaped linkage plate is fixedly connected to the surface of each of the two mounting plates. The two linkage plates are symmetrically arranged. An inclined pushing surface is provided on the linkage plate. Two pushing pins are fixedly connected to the top of the pushing plate.

[0014] Furthermore, a knob is fixedly connected to the end of the threaded rod, the knob being located inside the locking seat, and an operating handle is fixedly connected to the end of the adjusting rod, the operating handle being located inside the locking seat.

[0015] Compared with the prior art, the sealing and locking mechanism of the flywheel energy storage unit described in this invention has the following advantages:

[0016] (1) In the process of installing the flywheel energy storage unit described in this invention, the shaft with the flywheel body installed is inserted into the lower housing and supported by the lower bearing. Then, the upper cover is placed on the port of the lower housing. The upper cover and the outer side of the lower housing are snapped together by the snap-fit ​​assembly. The locking assembly locks the upper cover at the port of the lower housing. In the process of clamping the flywheel body, the clamping assembly is linked to the locking assembly to tighten the upper cover. This realizes that the clamping assembly is set inside the lower housing, so there is no need to install and remove the clamping assembly. The flywheel body can be clamped during the process of installing the upper cover and the lower housing. After the flywheel energy storage unit is moved into place, the clamping assembly can be removed from the flywheel body to resume operation, which simplifies the operation process.

[0017] (2) Before installation, the adjustment rod is pulled to make the inclined surface of the boss press against the edge of the clearance slot, so that the horizontal section is pushed and the vertical section of the connecting frame is pulled synchronously to compress the support spring. During the clamping process of the flywheel body, the boss is always between the horizontal section and the upper or lower adjustment plate to maintain support. When it is necessary to cancel the clamping, without the need to rotate the threaded rod for adjustment, the adjustment rod is pressed directly to move the push plate. The push plate drives the boss to move. When the boss moves to the clearance slot, under the action of the support spring, the connecting frame drives the clamping roller away from the flywheel body to cancel the clamping, which makes it convenient for the staff to quickly cancel the clamping component's clamping of the flywheel body.

[0018] During the process of the upper cover being placed onto the top of the lower housing, the guide surfaces of the two hook ends will press against the top of the hook plates, spreading the two hook plates apart until the hook ends move to the hook grooves. Then, under the action of the return spring, the hook plates are pushed back to their original positions, so that the hook grooves on the hook plates align with the hook ends, thus achieving the hooking of the hook body with the two hook plates. Then, the flywheel body is clamped by the clamping assembly. During the clamping process of the flywheel body, the two upper adjusting plates will move downwards, synchronously driving the hook plates to move. When the flywheel body is clamped, the hook plates tighten the hook body, thus pressing the upper cover and the lower housing together. This not only prevents the upper cover from detaching but also facilitates a tight seal between the top of the upper cover and the top of the lower housing. Attached Figure Description

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 12 As shown, in one embodiment, the sealing and locking mechanism of the flywheel energy storage unit includes a lower housing 1 and an upper cover 2. A shaft 3 is rotatably arranged between the lower housing 1 and the upper cover 2. The lower housing 1 has a first chamber 4 inside. A flywheel body 5 is fixedly sleeved on the surface of the shaft 3. The flywheel body 5 is located in the first chamber 4. The mechanism also includes multiple snap-fit ​​components, multiple clamping components, and multiple locking components. The multiple snap-fit ​​components are located at the joint between the upper cover 2 and the lower housing 1. The snap-fit ​​components are used to snap the outer sides of the upper cover 2 and the lower housing 1. The multiple clamping components are located inside the first chamber 4. The clamping components are used to clamp and support the flywheel body 5. The multiple locking components are all located inside the first chamber 4. The locking components are used to lock the upper cover 2 at the port of the lower housing 1. During the clamping process of the clamping components clamping the flywheel body 5, the locking components are linked to tighten the upper cover 2.

[0039] The upper cover 2 also has a second chamber 6, and the lower shell 1 also has a third chamber 8 that communicates with the first chamber 4. The top end of the shaft 3 is rotatably connected to the top end of the second chamber 6 through an upper bearing 7, and the bottom end of the shaft 3 is rotatably connected to the bottom end of the third chamber 8 through a lower bearing 44. A motor rotor 9 is also provided on the shaft surface of the shaft 3 between the flywheel body 5 and the lower bearing 44. The motor rotor 9 is located in the third chamber 8. A second magnetic levitation bearing assembly 10 is provided between the motor rotor 9 and the upper bearing 7 and between the flywheel body 5 and the upper bearing 7.

[0040] The second magnetic levitation bearing assembly 10 may include a rotating ring 1002 fixed to the shaft 3 and a stationary ring 1001 fixed to the inner wall of the second chamber 6 or the third chamber 8 and disposed opposite to the shaft 3. The rotating ring 1002 can rotate with the rotation of the shaft 3. The second magnetic levitation bearing assembly 10 can be one of a permanent magnet levitation bearing, an electromagnetic levitation bearing, and a hybrid magnetic levitation bearing. The motor rotor 9 can rotate with the rotation of the shaft 3.

[0041] The motor stator 11 is also fixedly connected inside the third chamber 8, and the motor stator 11 surrounds the outside of the motor rotor 9.

[0042] It should be understood that during the installation of the flywheel body 5 energy storage unit, the shaft 3 with the flywheel body 5 installed is inserted into the lower housing 1 and supported by the lower bearing 44. Then, the upper cover 2 is placed on the port of the lower housing 1, and the upper cover 2 and the outer side of the lower housing 1 are snapped together by the snap-fit ​​assembly. The locking assembly locks the upper cover 2 at the port of the lower housing 1. During the clamping process of the clamping assembly, the locking assembly pulls the upper cover 2 together. This achieves the goal of setting the clamping assembly inside the lower housing 1 without the need to install or remove the clamping assembly. The clamping of the flywheel body 5 can be achieved during the installation of the upper cover 2 and the lower housing 1. After the flywheel body 5 energy storage unit is moved into place, the clamping assembly can be removed from the flywheel body 5 to resume operation, simplifying the operation process.

[0043] like Figure 1 and Figure 2As shown, in one embodiment, multiple snap-fit ​​components each include a snap-fit ​​base 12 and an elastic snap fastener 13. Multiple snap-fit ​​bases 12 are fixedly connected to the outer surface of the lower housing 1. A snap-fit ​​opening 14 is provided at the top of each snap-fit ​​base 12. Multiple elastic snap fasteners 13 are fixedly connected to the surface of the upper cover 2. Each elastic snap fastener 13 passes through a multiple snap-fit ​​opening 14 and snaps onto the snap-fit ​​base 12. It should be understood that during the process of the upper cover 2 closing onto the lower housing 1, the elastic snap fastener 13 is aligned with the snap-fit ​​opening 14. When the elastic snap fastener 13 is fully inserted into the snap-fit ​​opening 14, under the elastic reset action of the elastic snap fastener 13, the snap-fit ​​end of the elastic snap fastener 13 will rest on the edge of the bottom end of the snap-fit ​​opening 14, achieving snap-fit ​​without the need for bolt fixation.

[0044] like Figure 3 , Figures 4 to 6 , Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, in one embodiment, multiple clamping components each include a clamping seat 15, a threaded sleeve 43, and four jaws. Multiple clamping seats 15 are fixedly connected to the inner wall of the first chamber 4. Each clamping seat 15 corresponds one-to-one with a multiple snap-fit ​​seat 12. Each clamping seat 15 has an adjustment cavity 1501. An upper adjustment plate 16 and a lower adjustment plate 17 are slidably disposed on both sides of the inner wall of the adjustment cavity 1501. Inclined grooves 1701 are formed on the surfaces of both the upper and lower adjustment plates 16 and 17, and the inclined groove 1701 on the upper adjustment plate 16 is aligned with... The inclined grooves 1701 on the lower adjusting plate 17 are symmetrically arranged in the adjusting cavity 1501. Each of the four inclined grooves 1701 is provided with a guide pin 18. A push plate 19 is fixedly connected between the four guide pins 18. A threaded rod 20 is rotatably connected to the surface of the push plate 19. A threaded sleeve 43 is fixedly connected to the inner wall of the snap-fit ​​seat 12. The threaded rod 20 passes through the clamping seat 15, the lower housing 1 and the snap-fit ​​seat 12 in sequence. The threaded rod 20 is threadedly connected to the threaded sleeve 43. The four jaws are respectively arranged on the upper adjusting plate 16 and the lower adjusting plate 17. It should be understood that after the upper cover 2 is installed onto the lower housing 1, rotating the threaded rod 20 will cause it to move within the threaded sleeve 43. Simultaneously, the threaded rod 20 will drive the push plate 19 to move, which in turn drives the guide pin 18 to move. The guide pin 18 will push the inclined groove 1701, causing the upper adjusting plate 16 and the lower adjusting plate 17 to move closer together. The upper adjusting plate 16 and the lower adjusting plate 17 will then drive the gripper to move until it clamps the surface of the flywheel body 5. After the flywheel body 5 energy storage unit is in place... When the rotating threaded rod 20 reverses, the threaded rod 20 pulls the push plate 19 under the action of the threaded sleeve 43. The push plate 19 drives the guide pin 18 to reset. The guide pin 18 acts on the inclined groove 1701, causing the upper adjusting plate 16 and the lower adjusting plate 17 to move away from each other. The upper adjusting plate 16 and the lower adjusting plate 17 will drive the gripper to move, canceling the clamping of the flywheel body 5. This allows the clamping assembly to be installed in the lower housing 1 without removal, making it convenient for staff to position and clamp the flywheel body 5 as needed.

[0045] like Figure 3 , Figure 4 and Figure 10As shown, in one embodiment, the gripper includes an L-shaped connecting frame 21, which includes a vertical section 2101 and a horizontal section 2102. The horizontal section 2102 located at the upper adjusting plate 16 is slidably connected to the side wall of the upper adjusting plate 16, and the vertical section 2101 located on the lower adjusting plate 17 is slidably connected to the side wall of the lower adjusting plate 17. Supporting springs 22 are fixedly connected between the vertical sections 2101 at different positions and the ends of the upper adjusting plate 16 and the lower adjusting plate 17, respectively. Release clamping components are provided between the bottom end of the upper adjusting plate 16 and the top end of the lower adjusting plate 17 and the corresponding horizontal sections 2102, respectively. A clamping roller 23 is provided at the end of the vertical section 2101. It should be understood that as the upper adjusting plate 16 and the lower adjusting plate 17 approach each other, the connecting frame 21 will move synchronously, and the connecting frame 21 will drive the clamping roller 23 to move, thereby clamping both sides of the flywheel body 5.

[0046] A threaded pin 25 is fixedly connected to the end of the clamping roller 23, and the threaded pin 25 is threadedly connected to the end of the vertical section 2101. It should be understood that during the process of inserting the shaft body 3 and the flywheel body 5 into the lower housing 1, the threaded pin 25 is first rotated to cancel the threaded connection with the connecting bracket 21 on the upper adjusting plate 16, so as to make way for the flywheel body 5 and avoid obstructing the flywheel body 5 from entering the lower housing 1.

[0047] Specifically, a rubber ring 24 is fitted on the surface of the clamping roller 23. By setting the rubber ring 24, it is beneficial to reduce the clamping damage of the clamping roller 23 to the surface of the flywheel body 5.

[0048] like Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, in one embodiment, the release clamping assembly includes a push port 26 and a clearance slot 27. The push port 26 passes through the threaded rod 20 and the push plate 19 in sequence. An adjusting rod 28 is slidably inserted into the push port 26. One end of the adjusting rod 28 is located in the snap-fit ​​seat 12, and the other end is located in the clamping seat 15. The end of the adjusting rod 28 located in the clamping seat 15 is fixedly connected to a moving plate 29. Two symmetrically arranged bosses 30 are fixedly connected to both sides of the moving plate 29. The bosses 30 include two inclined surfaces 3001 and a supporting surface 3002. The clearance slot 27 is opened on the connecting frame 21. The clearance slot 27 is located at the connection between the vertical section 2101 and the horizontal section 2102. The supporting surface 3002 of the boss 30 is in contact with the surface of the horizontal section 2102.

[0049] It should be understood that before installation, pulling the adjusting rod 28 causes the inclined surface 3001 of the boss 30 to press against the edge of the clearance slot 27, pushing the horizontal section 2102 and simultaneously pulling the vertical section 2101 of the connecting frame 21, compressing the support spring 22. During the clamping process of the flywheel body 5, the boss 30 is always between the horizontal section 2102 and the upper adjusting plate 16 or the lower adjusting plate 17 to maintain support. When it is necessary to cancel the clamping, without rotating the threaded rod 20 for adjustment, simply press the adjusting rod 28 to move the pushing plate 19. The pushing plate 19 drives the boss 30 to move. When the boss 30 moves to the clearance slot 27, under the action of the support spring 22, the connecting frame 21 drives the clamping roller 23 away from the flywheel body 5, canceling the clamping. This allows the staff to quickly cancel the clamping assembly's clamping of the flywheel body 5.

[0050] like Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 11 and Figure 12 As shown, in one embodiment, each of the multiple locking components includes two first connecting slots 31. The two first connecting slots 31 are opened at the ends of the two upper adjusting plates 16 in the adjusting cavity 1501. A hanging plate 32 is slidably connected in each of the two first connecting slots 31. A hanging slot 33 is opened on the hanging plate 32. A return spring 34 is fixedly connected between the hanging plate 32 and the inner wall of the first connecting slot 31. A hanging body 35 is inserted into both of the two first hanging slots 33. The top end of the hanging body 35 is fixedly connected to the bottom surface of the upper cover 2. Hanging ends 36 are fixedly connected to both sides of the bottom end of the hanging body 35. A guide surface 3601 is opened at the end of the hanging end 36. It should be understood that during the process of the upper cover 2 being placed on the top of the lower housing 1, the guide surfaces 3601 of the two hook ends 36 will press against the top of the hook plate 32, spreading the two hook plates 32 open until the hook end 36 moves to the hook groove 33. Then, under the action of the return spring 34, the hook plate 32 is pushed back to its original position, so that the hook groove 33 on the hook plate 32 is connected with the hook end 36, realizing the hooking of the hook body 35 with the two hook plates 32. Then, the flywheel body 5 is clamped by the clamping assembly. During the clamping of the flywheel body 5, the two upper adjusting plates 16 will move downward, synchronously driving the hook plate 32 to move. When the flywheel body 5 is clamped, the hook plate 32 pulls the hook body 35 tight, realizing the tightness between the upper cover 2 and the lower housing 1. On the one hand, it realizes the prevention of the upper cover 2 from detachment, and on the other hand, it is conducive to the tight sealing between the top of the upper cover 2 and the lower housing 1.

[0051] Specifically, a sealing ring 45 is provided at the top opening edge of the lower housing 1 to achieve a seal during the process of the upper cover 2 and the lower housing 1 being pressed together.

[0052] L-shaped linkage plates 41 are fixedly connected to the surfaces of both mounting plates 32. The two linkage plates 41 are symmetrically arranged, and inclined pushing surfaces 4101 are provided on the linkage plates 41. Two pushing pins 42 are fixedly connected to the top of the pushing plate 19. It should be understood that when it is necessary to remove the upper cover 2 from the lower housing 1, the threaded rod 20 is rotated first to pull the pushing plate 19, so that the pushing plate 19 drives the guide pin 18 to move the upper adjusting plate 16 and the lower adjusting plate 17 away from each other. At the same time, the pushing plate 19 drives the two pushing pins 42 to move until the two pushing pins 42 push the inclined pushing surface 4101, so that the linkage plate 41 drives the mounting plate 32 to disengage from the mounting end 36, canceling the locking component's locking and positioning of the upper cover 2, and preparing for the upper cover 2 to be removed from the lower housing 1.

[0053] like Figure 3 , Figure 4 and Figure 7 As shown, in one embodiment, a plurality of guide channels 37 are fixedly connected to the inner wall of the lower housing 1. The top opening edge of the guide channel 37 is chamfered, and a plurality of hangers 35 pass through the plurality of guide channels 37 respectively. Both sides of the guide channel 37 are provided with clearance channels 38 for the hanger end 36 to pass through. It should be understood that by setting the guide channels 37, the hangers 35 are guided and supported. During the process of the upper cover 2 covering the lower housing 1, the hangers 35 are first inserted into the guide channels 37 to achieve alignment, which provides favorable conditions for the docking of the elastic buckle 13 and the snap-fit ​​opening 14, as well as the alignment between the hanger 35 and the hanger plate 32.

[0054] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, a knob 39 is fixedly connected to the end of the threaded rod 20, and the knob 39 is located inside the locking seat 12.
