Description

Technical Field

[0001] This utility model relates to the field of battery retrieval and placement technology in battery energy storage stations, specifically a battery push-pull device. Background Technology

[0002] A battery energy storage station is a system that stores electrical energy through battery cells and other devices and releases it when needed. It is primarily used to balance grid supply and demand, improve stability, and promote the consumption of renewable energy. In a battery energy storage station, the battery cells (battery packs) are typically stacked, meaning they are placed in different compartments. During use, maintenance and replacement are inevitable, requiring the batteries to be pushed in or pulled out of their respective compartments. Since battery cells have a certain volume and weight, a dedicated battery pushing and pulling device needs to be designed.

[0003] To address this, Chinese utility model patent CN223342377U proposes a push-pull system for energy storage batteries, which is used in conjunction with a forklift. According to its disclosure, when pulling out the battery unit, the push-pull frame needs to be sent into the corresponding compartment in the energy storage cabinet by the rise and fall of the forklift forks, and is located below the battery unit. The forklift forks then rise, and the push-pull frame carries the battery unit. Then, the motor drives the push plate to move backward, thereby pulling the battery unit out of the energy storage cabinet.

[0004] However, in actual use, due to the limited space inside the energy storage cabinet, and the fact that there are usually other battery units above and below the battery unit to be pulled out, it is difficult to expect the aforementioned energy storage battery push-pull system to achieve the ability to quickly and effectively pull the battery unit out of the energy storage cabinet.

[0005] In addition, keeping the battery push-pull device and the corresponding compartment on the same horizontal plane is also one of the prerequisites for successfully pushing and pulling the battery cell in and out. Utility Model Content

[0006] The purpose of this invention is to overcome the defects and shortcomings of the existing technology and provide a battery push-pull device that can quickly and effectively push and pull battery cells into and out of the corresponding energy storage station compartment without entering the interior of the energy storage station, is not restricted by the limited space inside the energy storage station, and does not interfere with other battery cells. In addition, it can keep the transverse frame and the corresponding compartment on the same horizontal plane to smoothly push and pull the battery cells in and out.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A battery push-pull device includes a fixed frame and a transverse frame, characterized in that: the fixed frame can be inserted into the forks of a forklift; the transverse frame can rotate up and down around the front end of the fixed frame; a transverse slide is installed on the transverse frame, which can move laterally along its length direction for pushing and pulling battery units into and out of the corresponding energy storage station compartment; a transverse drive component is installed on the transverse frame for driving the transverse frame to move laterally; and a lifting component is installed at the rear end of the fixed frame for driving the transverse frame to rotate up and down.

[0008] Furthermore, the bottom surface of the fixed frame is fixedly connected with a fork sleeve extending along its width direction for insertion into the forklift forks.

Several heavy-duty universal balls are installed on the inner side of the corresponding guide rails on both sides of the transverse frame. The several heavy-duty universal balls are distributed at intervals along the length direction of the transverse frame to guide the battery units entering and exiting.

[0012] Furthermore, a push rod extending along the width direction of the transverse slide is fixedly connected to the front side of the transverse slide, which is used to push the battery unit into the corresponding energy storage station compartment. Both ends of the front side of the transverse slide are fixedly connected to forward-extending pull ropes. A pull ring is fixedly connected to the front end of the pull rope, and a threaded connector is rotatably connected to the front end of the pull ring, which is used to engage with the screw holes on both sides of one end of the battery unit.

The lead screw is rotatably mounted between the front and rear crossbeams of the lateral movement frame, and the motor is fixedly mounted on the rear crossbeam of the lateral movement frame and is connected to the rear end of the lead screw via a sprocket and a chain.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figure 1-5 A battery push-pull device includes a fixed frame 1 and a transverse frame 2. The fixed frame 1 can be inserted into the forks of a forklift. The transverse frame 2 can rotate up and down around the front end of the fixed frame 1. A transverse slide 3 that can move laterally along its length is installed on the transverse frame 2 for pushing and pulling battery units into and out of the corresponding energy storage station compartment. A transverse drive component 4 is installed on the transverse frame 2 for driving the transverse frame 2 to move laterally. A lifting component 5 is installed at the rear end of the fixed frame 1 for driving the transverse frame 2 to rotate up and down.

[0025] In this utility model, a fork sleeve 6 extending along its width direction is fixedly connected to the bottom surface of the fixed frame 1.

[0026] When in use, the forklift forks are directly inserted into the fork sleeve 6 to achieve cooperation with the forklift.

[0027] In this invention, the front ends of the fixed frame 1 and the transverse frame 2 are rotatably connected.

[0028] In this utility model, the lifting component 5 is a scissor jack, and the upper and lower ends of the scissor jack 5 are respectively rotatably connected to the rear ends of the fixed frame 1 and the transverse frame 2.

[0029] Therefore, by using the horizontal screw of the forward and reverse lifting component 5, and utilizing the stability principle of the isosceles triangle, the upper and lower supports are driven to perform telescopic movements, so that the horizontal moving frame 2 used to support the battery unit can rotate up and down around the front end of the fixed frame 1 at a certain angle, thereby keeping the horizontal moving frame 2 and the corresponding partition on the same horizontal plane and achieving leveling.

[0030] In this utility model, guide rails 18 extending along the length direction are fixedly connected to both sides of the transverse frame 2, and rollers 7 that can move along the corresponding guide rails 18 are installed at both ends of the transverse slide 3. Several heavy-duty universal balls 8 are installed on the inner side of the corresponding guide rails 18 on both sides of the transverse frame 2. The several heavy-duty universal balls 8 are distributed at intervals along the length direction of the transverse frame 2 to provide guidance for the battery unit to enter and exit, so as to facilitate the battery unit to enter and exit the transverse frame 2.

[0031] In this utility model, a push rod 9 extending along the width direction of the transverse slide 3 is fixedly connected to the front side of the transverse slide 3, which is used to push the battery unit into the corresponding energy storage station compartment. Both ends of the front side of the transverse slide 3 are fixedly connected to a pull rope 10 extending forward. A pull ring 11 is fixedly connected to the front end of the pull rope 10. A threaded connector 12 is rotatably connected to the front end of the pull ring 11, which is used to engage with the screw holes on both sides of one end of the battery unit, thereby realizing the detachable connection with the battery unit, and thus realizing the pulling of the battery unit out of the corresponding energy storage station compartment.

[0032] In this utility model, the transverse drive component 4 includes a lead screw 41 and a motor 42 capable of forward and reverse rotation. The lead screw 41 is rotatably mounted between the front and rear crossbeams of the transverse frame 2, and the motor 42 is fixedly mounted on the rear crossbeam of the transverse frame 2 and is connected to the rear end of the lead screw 41 through a sprocket 43 and a chain 44.

[0033] In this utility model, the bottom of the transverse slide 2 is installed on the lead screw 41 by a threaded connection.

[0034] Thus, the motor 42 rotates forward and backward, driving the lead screw 41 to rotate forward and backward, causing the transverse slide 3 to move forward and backward along the lead screw 41. At the same time, the rollers 7 move forward and backward along the guide rails 18 on both sides. The push rod 9 pushes the battery unit into the corresponding energy storage station compartment, and the pull rope 10 pulls the battery unit out of the corresponding energy storage station compartment.

[0035] In this utility model, limit switches 13 are installed on the front and rear crossbeams of the transverse frame 2, and a camera 14 with the lens facing forward is installed on the transverse slide 3; a pull-wire sensor 15 is fixedly installed on one side of the rear end of the transverse frame 2, and a fixed base 16 is fixedly installed on one side of the transverse slide 3, with the wire end of the pull-wire sensor 15 fixedly connected to the fixed base 16.

[0036] In this utility model, a control panel 17 is installed on one side of the transverse frame 2. The control panel 17 is electrically connected to the limit switch 13 and the pull wire sensor 15 on one side, electrically connected to the motor 42 on the other side, and wirelessly connected to the camera 14 on the third side.

[0037] Therefore, the limit switch 13 detects the forward and backward positioning signals of the transverse slide 3 and feeds them back to the control unit of the control panel 17, thereby controlling the motor 42 to start and stop, so that the transverse slide 3 can always operate within the safe travel range.

[0038] Of course, operators can also control the operation of motor 42 by operating the corresponding function buttons on the control panel 17, including but not limited to controlling the start, stop and speed of motor 42, thereby controlling the forward and backward movement of transverse slide 3, and thus controlling the pushing in and pulling out of battery unit.

[0039] The camera 14 captures real-time images or videos and sends them to the control screen 17 for real-time display. This allows for the real-time display and recording of the entire process of pushing the battery unit in and pulling it out, facilitating operation and improving safety.

[0040] In addition, the end of the pull cable sensor 15 moves laterally with the transverse slide 3, causing the pull cable of the pull cable sensor 15 to extend and retract. The internal encoder records the extension and retraction length of the pull cable and converts it into an electrical signal, which is sent to the control unit of the control panel 17. The control unit calculates the forward and backward displacement of the transverse slide 3, which is then displayed in real time by the control panel 17 to reflect the length of the battery unit being pushed in and pulled out.

[0041] It should be noted that the control panel 17 is detachable. When pushing or pulling the battery units on the upper floors, the operator can operate it while standing on the ground by holding the control panel 17.

[0042] In addition, the wiring between the control panel 17 and the limit switch 13 and the pull-wire sensor 15 should be of sufficient length to accommodate the height changes of the transverse frame 2 when the control panel 17 is held in the hand, and these wirings should be properly routed to avoid interfering with the normal forward and backward movement of the transverse slide 3.

[0043] The present invention will be further described below with reference to the accompanying drawings: When in use, insert the forklift forks into the fork sleeve 6, keeping the front ends of the fixed frame 1 and the transverse frame 2 facing the energy storage station (energy storage cabinet), without entering the interior of the energy storage station.

[0044] Operate the forklift to raise and lower its forks until it reaches the height of the corresponding battery cell (battery pack) compartment. Then insert a wrench into the hole at one end of the horizontal screw of the lifting component 5, and then drive the upper and lower supports to extend and retract by turning the horizontal screw forward and backward. This flips the horizontal frame 2 up and down to a certain angle, so as to keep the horizontal frame 2 and the corresponding compartment on the same horizontal plane, thereby achieving leveling.

[0045] When a battery unit needs to be pushed in, the motor 42 is started and rotates forward, driving the lead screw 41 to rotate forward, so that the transverse slide 3 moves forward along the lead screw 41 and moves forward along the guide rails 18 on both sides via the rollers 7. The push rod 9 pushes the battery unit from the transverse frame 2 into the corresponding energy storage station compartment.

[0046] When the battery unit needs to be pulled out, first screw the threaded connectors 12 on both sides into the threaded holes on both sides of one end of the battery unit, then start the motor 42. The motor 42 reverses and drives the lead screw 41 to reverse, so that the transverse slide 3 moves backward along the lead screw 41. At the same time, it moves backward along the guide rails 18 on both sides through the rollers 7. The pull rope 10 pulls the battery unit out from the corresponding energy storage station partition and moves it onto the transverse frame 2.

[0047] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0048] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
