Description

Technical Field

[0001] This invention relates to the field of energy storage technology, and in particular to an elevator energy storage device and the elevator thereof. Background Technology

[0002] Modern elevators mainly consist of a traction machine (winch), guide rails, counterweight, safety devices (such as speed governors, safety brakes, and buffers), signal control system, car, and landing doors. These components are installed in the building's hoistway and machine room, respectively. They typically use friction drive with steel wire ropes. The steel wire ropes pass around the traction sheave, with each end connected to the car and the counterweight, respectively. A motor drives the traction sheave to raise and lower the car. Elevators are required to be safe and reliable, have high transport efficiency, accurate leveling, and comfortable rides. The basic parameters of an elevator mainly include rated load capacity, passenger capacity, rated speed, car dimensions, and hoistway type. Power is supplied to the elevator through an energy storage device.

[0003] In existing technologies, elevator energy storage devices are equipped with ventilation holes for heat dissipation during operation. At the same time, in order to reduce the humidity of the elevator energy storage device during operation, desiccant packs are placed at the ventilation points for drying and dehumidification to ensure the working effect of the elevator energy storage device. However, the desiccant packs need to be replaced after a period of use. Currently, the desiccant packs need to be replaced manually by staff periodically, which increases the workload of staff and has certain limitations. Therefore, it is necessary to design an elevator energy storage device and its elevator to solve the above problems.

[0029] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] See Figure 1 , Figure 2 and Figure 3 The present invention provides an elevator energy storage device, comprising:

[0031] Elevator energy storage cabinet 1 and drying components, wherein:

[0032] An energy storage module 2 is installed inside the elevator energy storage cabinet 1. Ventilation holes 3 are opened on both sides of the elevator energy storage cabinet 1. Dustproof nets 4 are fixedly installed inside the ventilation holes 3. It should be noted that the energy storage module 2 is connected to the State Grid for power supply. The energy storage module 2 can power the elevator frequency converter, which provides electrical energy to the traction machine. It is suitable for low-rise villa elevators. Its specific structure is existing technology and will not be described in detail here. The energy storage module 2 can be a lithium battery pack Vbat.

[0033] The drying assembly is installed inside the elevator energy storage cabinet 1. The drying assembly includes a placement frame 5, a top-out block 7, a bottom plate 8, a side plate 9, a sealing plate 10, a frame 13, a dual-axis motor 14, a screw 15, and a storage mesh frame 17. The placement frame 5 is fixedly installed on the top inner wall of the elevator energy storage cabinet 1. Multiple drying packs 6 are stacked inside the placement frame 5. It should be noted that the drying packs 6 are used to dry the inside of the elevator energy storage cabinet 1.

[0034] The ejector block 7 is fixedly connected to the side of the base plate 8, the top of the base plate 8 is fixedly connected to the side plate 9, the side of the side plate 9 is fixedly connected to the sealing plate 10, and the side of the placement frame 5 is provided with a sealing hole 11. The sealing plate 10 is in sealing contact with the sealing hole 11. It should be noted that this can be used to seal and preserve the desiccant 6 stored in the placement frame 5.

[0035] The side of the ejector block 7 contacts the drying package 6. The frame 13 is fixedly installed on the placement frame 5. The dual-axis motor 14 is fixedly installed at the bottom of the frame 13. The output end of the dual-axis motor 14 is fixedly connected to the screw 15. The side of the ejector block 7 is provided with a screw hole, and the screw 15 is threadedly connected to the screw hole.

[0036] With the above structure, after the drying pack 6 in the storage frame 17 has been used for a specified time, the dual-axis motor 14 is started. The dual-axis motor 14 drives the screw 15 to rotate, which in turn causes the ejector block 7 to move. The ejector block 7, the bottom plate 8, the side plate 9 and the sealing plate 10 move synchronously, which can eject the bottom drying pack 6 and let it fall into the storage frame 17 through the discharge hole 12 on the bottom plate 8. New drying packs 6 are added to the storage frame 17, and the drying process continues. Then the ejector block 7, the bottom plate 8, the side plate 9 and the sealing plate 10 are returned to their original positions.

[0037] Specifically, the drying assembly also includes a support plate 16, a mesh plate 18, a clamping plate 19, and a positioning screw 20. The support plate 16 is fixedly installed on the side wall of the elevator energy storage cabinet 1, and the mesh plate 18 is fixedly installed inside the storage mesh frame 17. It should be noted that the storage mesh frame 17 and the mesh plate 18 have a large number of holes on their surfaces, which will not affect the air circulation. Therefore, the setting of the storage mesh frame 17 and the mesh plate 18 will not affect the normal ventilation of the elevator energy storage cabinet 1.

[0038] The card plate 19 is fixedly installed at the bottom of the storage frame 17. The top of the support plate 16 has a card slot, and the card plate 19 is engaged with the card slot. The positioning screw 20 is threadedly installed on the support plate 16. The bottom of the card plate 19 has a positioning screw groove, and the positioning screw 20 is threadedly connected to the positioning screw groove.

[0039] With the above structure, the drying pack 6 is stored on the mesh plate 18 inside the storage mesh frame 17. After a large number of used drying packs 6 are stored in the storage mesh frame 17, the storage mesh frame 17 can be removed to clean the used drying packs 6 inside.

[0040] Working principle:

[0041] S1: After the drying pack 6 in the storage frame 17 has been used for a specified time, the controller 21 starts the dual-axis motor 14. The dual-axis motor 14 drives the screw 15 to rotate. Through the connection between the screw 15 and the screw hole, the ejector block 7, the bottom plate 8, the side plate 9 and the sealing plate 10 can move synchronously, which can eject the bottom drying pack 6. The ejected drying pack 6 falls into the storage frame 17 through the discharge hole 12 on the bottom plate 8. New drying packs 6 are added to the storage frame 17 in this way, and the drying process continues. Then the ejector block 7, the bottom plate 8, the side plate 9 and the sealing plate 10 are returned to their original positions. The drying packs 6 do not need to be replaced by the staff frequently, which effectively reduces the workload of the staff.

[0042] S2: After storing a large number of used desiccant packs 6 in the storage frame 17, rotate the positioning screw 20 so that the positioning screw 20 is unscrewed from the positioning screw groove. Then, remove the storage frame 17 and clean the used desiccant packs 6 inside.

[0043] Specifically, the bottom plate 8 has a feeding hole 12 at the top and the placement frame 5 has an adding hole on the side. A sealing plug 22 is installed in the adding hole. It should be noted that the feeding hole 12 is designed to allow a desiccant 6 to be added into the storage frame 17, and the adding hole is designed to allow new desiccant 6 to be added into the placement frame 5.

[0044] Specifically, a controller 21 is fixedly installed on the inner wall of the top of the elevator energy storage cabinet 1. The controller 21 is electrically connected to the dual-axis motor 14. It should be noted that the controller 21 automatically controls the dual-axis motor 14.

[0045] Specifically, a horizontal hole is provided on the side of the placement frame 5, and the ejector block 7 is slidably installed in the horizontal hole. It should be noted that this facilitates the horizontal movement of the ejector block 7.

[0046] Specifically, the top of the support plate 16 is in contact with the storage frame 17. It should be noted that the storage frame 17 can be supported.

[0047] This application also provides the following technical solutions:
