Description

Technical Field

[0001] This utility model relates to the technical field of energy storage, and in particular to a mobile mechanism and a grid-integrated energy storage device. Background Technology

[0002] In modern power grid systems, grid-integrated energy storage devices play a crucial role in regulating power supply and demand and improving power quality. To meet the needs of flexible deployment and installation, existing technologies have greatly improved the ease of transportation by setting a moving mechanism at the bottom of the energy storage device, which includes rollers. However, in actual use, this design has revealed obvious shortcomings.

[0003] Rollers are typically installed inside a box at the bottom of the energy storage device. To allow the rollers to move in and out normally, a through hole needs to be made at the bottom of the box. However, this through hole is open, allowing external dust, debris, and other impurities to enter the box without obstruction. The accumulation of impurities not only affects the mechanical performance of the rollers, increases wear and jamming during operation, and reduces their stability and safety, but in severe cases, it can even lead to equipment failure and affect the normal operation of the power grid. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a mobile mechanism and a grid-integrated energy storage device. It has a simple structure, can block the opening, prevent dust from entering the box and affecting the rollers, and improve the operational stability of the internal structure of the box.

[0005] The present invention provides a mobile mechanism, including a box, a lifting plate and rollers; the rollers are arranged side by side at the bottom of the lifting plate, and through holes for the rollers to enter and exit are opened at corresponding positions at the bottom of the box. Two baffles are slidably arranged at each through hole, and the baffles on the same side are connected by a connector.

[0006] Also includes:

[0007] A lifting mechanism located inside the box to drive the lifting platform up and down;

[0008] The pivot rotates at the bottom of the box and is located between two connecting parts; the pivot is fixed to the middle of the drive arm, and the two ends of the drive arm are slidably connected to the two connecting parts respectively.

[0009] As a preferred embodiment of this utility model, two adjacent rotating shafts are connected by a transmission connection;

[0010] A power mechanism is fixed at the bottom of the box, and the output shaft of the power mechanism is connected to one of the rotating shafts.

[0011] As a preferred embodiment of this utility model, a notch is provided on the baffle, and the roller is installed on the lifting plate through an extension;

[0012] In this configuration, after the roller extends out of the box, the extension passes through the notch.

[0013] As a preferred embodiment of this utility model, an elastic element is provided at the notch.

[0014] As a preferred embodiment of this utility model, the lifting mechanism includes:

[0015] At least two symmetrically arranged fixing members are connected to the lifting plate. The fixing members are provided with horizontal hole one and horizontal hole two with a height difference. Horizontal hole one and horizontal hole two are connected by an oblique hole.

[0016] Rotate the double-threaded screw installed inside the box. The double-threaded screw is threaded with a moving block. The moving block is fixedly connected to a drive shaft that moves along horizontal hole one, horizontal hole two and oblique hole.

[0017] The lead screw has a power mechanism two fixed at its end.

[0018] As a preferred embodiment of the present invention, it further includes two controllers for controlling the action of a power mechanism.

[0019] When one of the drive shafts is at the end of the horizontal hole one that is far from the end of the inclined hole, and when the drive shaft is at the end of the horizontal hole two that is far from the end of the inclined hole, the two controllers are triggered respectively.

[0020] As a preferred embodiment of this utility model, the bottom of the box is equipped with supporting feet.

[0021] A grid-integrated energy storage device includes any one of the aforementioned moving mechanisms.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: When the energy storage device needs to be moved using rollers, the lifting mechanism is activated to push the lifting plate downward. At this time, the rollers move downward with the lifting plate, gradually approaching the through hole at the bottom of the box. Simultaneously, the rotating shaft is controlled to rotate, which drives the drive arm to rotate. Since the two ends of the drive arm are slidably connected to the connecting parts, the rotation of the drive arm will drive the connecting parts to move, thereby causing the two baffles at the same through hole to slide in opposite directions, opening the through hole and allowing the rollers to smoothly extend out of the bottom of the box, realizing the movement of the energy storage device. When the rollers are not needed, the lifting mechanism drives the lifting plate to rise, and the rollers retract into the box. At the same time, the rotating shaft rotates in the opposite direction, causing the baffles to close the through hole. By controlling the lifting and lowering of the rollers through the lifting mechanism and controlling the opening and closing of the baffles through the rotating shaft and drive arm, the through hole is opened when the rollers are in use and closed when not in use. This effectively prevents external dust, debris and other impurities from entering the box, protects the mechanical properties of the rollers, reduces roller wear and jamming, improves the stability and safety of the moving mechanism, extends the service life of the equipment, and ensures the normal operation of the power grid.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example

[0033] Reference Figure 1 , Figure 4 and Figure 5This embodiment provides a moving mechanism, including a box 1, a lifting plate 2, and rollers 3. The lifting plate 2 slides longitudinally inside the box 1 and can slide by means of a telescopic rod or a track. The rollers 3 are arranged side by side at the bottom of the lifting plate 2. In this embodiment, there are two rows of rollers 3, with two rollers in each row. The rollers 3 are made of wear-resistant rubber material to adapt to different ground environments.

[0034] A through hole 4 is made at the corresponding position on the bottom of the box 1 for the roller 3 to enter and exit. In this embodiment, the roller 3 is a universal wheel, and the through hole 4 is circular in shape and coaxial with the axis of the universal wheel so that the universal wheel can enter and exit the box 1 at any angle.

[0035] Two baffles 5 are slidably installed at each through hole 4. More specifically, a guide rail for sliding the baffles 5 is fixed at the bottom of the box 1. The baffles 5 on the same side are connected by connectors 6. The connection method can be bolts or welding.

[0036] Also includes:

[0037] The lifting mechanism 7, located inside the box 1, is used to drive the lifting plate 2 to rise and fall.

[0038] The rotating shaft 8 rotates at the bottom of the box 1 and is located between the two connecting parts 6. More specifically, the rotating shaft 8 is rotatably mounted at the bottom of the box 1 via bearings to ensure its rotational flexibility.

[0039] The middle part of the drive arm 9 is fixed to the rotating shaft 8. The drive arm 9 is made of metal plate, and its middle part is fixed to the rotating shaft 8 by welding or key connection. The two ends of the drive arm 9 are slidably connected to two connecting parts 6 respectively. More specifically, the connecting parts 6 have elongated holes along the length direction of the connecting parts 6, and fixed shafts extending into the elongated holes are fixed at both ends of the drive arm 9.

[0040] The specific process of this device is as follows: When the roller 3 needs to be used to move the energy storage device, the lifting mechanism 7 is activated, which pushes the lifting plate 2 down. At this time, the roller 3 moves downward with the lifting plate 2, gradually approaching the through hole 4 at the bottom of the box 1; at the same time, the rotating shaft 8 is controlled to rotate, and the rotating shaft 8 drives the drive arm 9 to rotate. Since the two ends of the drive arm 9 are slidably connected to the connecting parts 6, the rotation of the drive arm 9 will drive the connecting parts 6 to move, thereby causing the two baffles 5 at the same through hole 4 to slide in opposite directions, opening the through hole 4, allowing the roller 3 to smoothly extend out of the bottom of the box 1, realizing the movement of the energy storage device. When it is not needed, the roller 3 can be moved. When roller 3 is in use, lifting mechanism 7 drives lifting plate 2 to rise, and roller 3 retracts into box 1. At the same time, rotating shaft 8 rotates in the opposite direction, causing baffle 5 to close through hole 4. The lifting mechanism 7 controls the raising and lowering of roller 3, and the rotating shaft 8 and drive arm 9 control the opening and closing of baffle 5. When roller 3 is in use, through hole 4 is open, and when not in use, through hole 4 is closed. This effectively prevents external dust, debris and other impurities from entering the box 1, protects the mechanical properties of roller 3, reduces wear and jamming of roller 3, improves the stability and safety of the moving mechanism, extends the service life of the equipment, and ensures the normal operation of the power grid.

[0041] As a preferred embodiment of this utility model, refer to Figure 3 and Figure 5 The two adjacent rotating shafts are connected by a transmission, and more specifically, the two can be driven by a chain or a synchronous belt.

[0042] A power mechanism 10 is fixed at the bottom of box 1. The output shaft of the power mechanism 10 is connected to one of the rotating shafts 8. More specifically, the power mechanism 10 is a flat motor. This type of motor has the characteristics of small thickness, which can effectively reduce the height occupied. The flat motor is fixed to the bottom of box 1 with bolts. It drives the rotating shaft 8 to rotate through chain drive or synchronous belt drive.

[0043] By connecting adjacent rotating shafts 8 through transmission and using a flat motor as the power mechanism, multiple rotating shafts 8 can be rotated synchronously by controlling only one motor, thereby controlling the synchronous opening and closing of multiple baffles 5. This design simplifies the control structure, reduces the number of power devices used, and lowers costs. At the same time, the flat motor reduces the height occupied, making the structure of the entire moving mechanism more compact and suitable for application scenarios with high space requirements. The collaborative work of multiple components improves the overall performance and practicality of the moving mechanism.

[0044] As a preferred embodiment of this utility model, refer to Figure 4 and Figure 5 The baffle 5 has a notch 11. The roller 3 is installed on the lifting plate 2 through an extension. The extension is columnar and its cross-sectional shape can be circular or other shapes. The function of the extension is to increase the distance between the roller 3 and the lifting plate 2 so that the baffle 5 can work normally.

[0045] Among them, after the roller 3 extends out of the box 1, the extension passes through the notch 11. The shape of the notch 11 should be the same as half of the shape of the outer wall of the extension to reduce the gap between the baffle 5 and the extension.

[0046] When the roller 3 extends out of the bottom of the box 1 under the drive of the lifting mechanism 7, the extension moves downward along with the roller 3. When the roller 3 is fully extended out of the box 1, the extension passes through the notch 11 on the baffle 5. At this time, the rotating shaft 8 reverses, causing the baffle 5 to close. Since the extension passes through the notch 11, the baffle 5 will not interfere with the extension during the movement. Furthermore, the notch 11 reduces the space between the box 1 and the outside world, further preventing dust, debris and other impurities from entering the box 1. At the same time, the sealing of the moving mechanism is improved without affecting the normal use of the roller 3.

[0047] As a preferred embodiment of this utility model, refer to Figure 5 An elastic element 12 is provided at the notch 11. More specifically, the elastic element 12 can be made of a material that can undergo elastic deformation, such as sponge.

[0048] When the roller 3 is inside the box 1, the two baffles 5 close under the action of the rotating shaft 8 and the drive arm 9. At this time, the elastic element 12 naturally extends and tightly seals the notch 11, so that the entire through hole 4 is completely closed, effectively preventing external dust, debris and other impurities from entering the box 1. When the roller 3 needs to be used, the roller 3 extends out of the box 1 under the drive of the lifting mechanism 7. The extension passes through the notch 11 and then the baffle 5 is reset. During this process, the extension will squeeze the elastic element 12, causing the elastic element 12 to deform and tightly seal the gap between the baffle 5 and the extension.

[0049] As a preferred embodiment of this utility model, refer to Figure 2 and Figure 3 The lifting mechanism 7 includes:

[0050] At least two fixing members 71 are symmetrically arranged and connected to the lifting plate 2. In this embodiment, there are two fixing members 71 on one side to improve the stability during lifting.

[0051] The fastener 71 has a horizontal hole 72 and a horizontal hole 73 with a height difference. The horizontal hole 72 and the horizontal hole 73 are connected by an oblique hole 74. The positions of the horizontal hole 72 and the horizontal hole 73 should be set according to the moving direction of the drive shaft 77.

[0052] A bidirectional threaded screw 75 is rotatably mounted in the housing 1 via a bearing. The bidirectional threads of the screw 75 are threadedly connected to a moving block 76. The moving block 76 is fixedly connected to a drive shaft 77 that moves along horizontal hole 1 72, horizontal hole 2 73 and inclined hole 74. In order to prevent the moving block 76 from rotating with the screw 75, a track that is slidably connected to the moving block 76 is fixed in the housing 1.

[0053] Among them, a second power mechanism 78 is fixed to the end of the lead screw 75. The second power mechanism 78 is a motor, and the output shaft of the motor is fixedly connected to the end of the lead screw 75 through a coupling, gear, chain, or synchronous belt, so as to provide power for the rotation of the lead screw 75.

[0054] The specific working process of the lifting mechanism 7 is as follows: When it is necessary to lift the roller 3, the second power mechanism 78 is started, and the motor drives the bidirectional threaded screw 75 to rotate. Since the bidirectional thread of the screw 75 is connected to the moving block 76, the rotation of the screw 75 will cause the two moving blocks 76 to move in opposite directions, and drive the shaft 77 to move together with the moving block 76. When the drive shaft 77 moves in the first horizontal hole 72, the lifting plate 2 remains horizontal. When the drive shaft 77 moves to the inclined hole 74, since the inclined hole 74 has a certain tilt angle, the movement of the drive shaft 77 in the inclined hole 74 will cause the fixing part 71 to move up and down, thereby driving the lifting plate 2 to rise or fall, realizing the extension or retraction of the roller 3. When the drive shaft 77 moves to the second horizontal hole 73, the lifting plate 2 remains horizontal again.

[0055] As a preferred embodiment of this utility model, refer to Figure 2 and Figure 3 It also includes two controllers 13 for controlling the action of the power mechanism 10. The controllers 13 are sensitive and reliable sensor controllers 13, which are respectively installed at the end of the horizontal hole 1 72 away from the inclined hole 74 and the end of the horizontal hole 2 73 away from the inclined hole 74, to ensure that the controllers 13 can accurately detect the position of the drive shaft 77.

[0056] When one of the drive shafts 77 is at the end of the horizontal hole 72 that is away from the inclined hole 74, and when the drive shaft 77 is at the end of the horizontal hole 73 that is away from the inclined hole 74, the two controllers 13 are triggered respectively.

[0057] When roller 3 is inside box 1, drive shaft 77 is located at the end of horizontal hole 72 away from inclined hole 74, triggering one of the controllers 13. At this time, if it is necessary to move roller 3 out of box 1, power mechanism 2 78 is activated, and drive shaft 77 begins to move along horizontal hole 72. When drive shaft 77 disengages from controller 13, controller 13 sends a signal to cause power mechanism 10 to operate once. Power mechanism 10 drives shaft 8 to rotate, which opens baffle 5 through drive arm 9, exposing through hole 4. Then, drive shaft 77 passes through inclined hole 74, lifting plate 2 and roller 3 descend, and drive shaft 77 moves along horizontal hole 73. When the wheel moves to the end away from the inclined hole 74, it triggers another controller 13, which sends a signal to cause the power mechanism 10 to reverse and drive the baffle 5 to close. Similarly, when the roller 3 moves inside the box 1, the drive shaft 77 first disengages from the controller 13, which controls the power mechanism 10 to open the baffle 5. Then the drive shaft 77 passes through the horizontal hole 73, the inclined hole 74 and the horizontal hole 72, and triggers another controller 13 to close the baffle 5 and shut off the through hole 4. By setting two controllers 13 and combining them with the position change of the drive shaft 77, automatic control of the opening and closing of the baffle 5 is achieved.

[0058] As a preferred embodiment of this utility model, refer to Figure 1 The bottom of the box 1 is equipped with support feet. When the energy storage device is not moving, the rollers 3 retract into the box 1. At this time, the support feet are in contact with the ground and bear the weight of the entire energy storage device. Due to the presence of the support feet, the bottom of the box 1 is kept at a certain distance from the ground to avoid the box 1 being directly in contact with the ground and being affected by moisture, corrosion and other factors.

[0059] A grid-integrated energy storage device, with reference to Figure 1 Including any of the aforementioned moving mechanisms, more specifically, box 1 is installed at the bottom of the energy storage device, integrating the moving mechanism into the grid-integrated energy storage device, which enables the energy storage device to move flexibly. This not only solves the problem of inconvenient movement of traditional energy storage devices, but also ensures that the internal equipment is not affected by external impurities through the protective design of the moving mechanism, thereby improving the overall reliability and practicality of the energy storage device and promoting the smooth progress of power supply and demand regulation and power quality improvement in the power grid system.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
