Description

Technical Field

[0001] This utility model belongs to the field of energy storage technology, specifically a battery energy storage cabinet that facilitates quick replacement of battery packs. Background Technology

[0002] A battery energy storage cabinet is a device used to store and release electrical energy. Its core function is to convert electrical energy into chemical energy through batteries for storage and to convert it back into electrical energy for output when needed.

[0003] The core component of a battery storage cabinet is the battery pack installed inside. Multiple battery packs can be connected to form a battery pack according to usage requirements. The battery pack is mainly responsible for storing and releasing energy. Since the battery pack is heavy, when it needs to be replaced, a forklift or other equipment is usually used to remove the battery pack. However, because the internal space of the storage cabinet is relatively compact and there are many parts, the load-bearing mechanism of the forklift or other equipment is prone to conflict with other components when sending the battery pack into the storage cabinet.

[0004] Therefore, this utility model provides a battery energy storage cabinet that facilitates quick replacement of battery packs. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A battery storage cabinet for quick battery pack replacement, comprising a cabinet; a movable frame slidably connected to the middle of the cabinet; a pair of pulleys rotatably connected to the top of the movable frame; a cable sleeved in the middle of the pair of pulleys; a winding mechanism installed inside the cabinet; the end of the cable connected to the winding mechanism; a bearing plate rotatably connected to the middle of the movable frame; support rods rotatably connected to both sides of the bearing plate; a connecting bolt threaded to the middle of the support rod; a first insertion hole opened at the bottom of the side wall of the movable frame; an adjustment mechanism installed on the top of the bearing plate; the adjustment mechanism includes multiple rollers. With the above structure, the battery pack can be quickly and conveniently replaced without the use of forklifts or other devices, reducing the possibility of structural damage caused by collisions between the forks of forklifts and other devices when the battery pack is inserted into the cabinet.

[0007] Preferably, the adjustment mechanism includes a lead screw, an adjustment knob, a moving frame, and a circular roller; the lead screw is rotatably connected to the middle of the support plate; the adjustment knob is fixedly connected to the end of the lead screw; the moving frame is threadedly connected to the middle of the adjustment knob; the moving frame is slidably connected to the middle of the support plate; and the circular roller is rotatably connected to the middle of the moving frame. With this structure, the position of the battery pack can be easily adjusted when there is a positional deviation when the battery pack is placed on the support plate. This reduces the likelihood of the battery pack being obstructed by conflict with other components when pushing it towards the installation position inside the cabinet, further improving the ease of battery pack installation.

[0008] Preferably, a limiting rod is rotatably connected to the top of the support plate; a movable rod is slidably connected to the middle of the limiting rod; and a slot is provided in the middle of the support plate. With the above structure, when the battery pack is moved up and down by the support plate, the occurrence of the battery pack slipping due to the rotation of the roller can be reduced, thereby improving the safety of the device.

[0009] Preferably, the side wall of the movable frame is provided with a second insertion hole; the side wall of the support plate is provided with a third insertion hole; with the above structure, after the battery pack is replaced, the support plate and support rod can be folded and their positions restricted, and then the support plate and support rod can be moved to a height with less obstruction, reducing the space occupation of the energy storage cabinet and reducing the obstruction to the daily use of the energy storage cabinet, thus improving the ease of use of the device.

[0010] Preferably, the adjustment knob has multiple through holes arranged in a circular array in its center; an operating rod is detachably installed in the center of each through hole; a mounting groove is provided on the side wall of the support plate; and a buckle is fixedly connected to the inner side wall of the mounting groove. With the above structure, the resistance to rotation can be reduced when the adjustment knob is turned, and the operating tool can be directly stored in the mounting groove, so that there is no need to find the appropriate tool in subsequent use, thus improving the ease of use of the device.

[0011] Preferably, elastic sleeves are fixed to both sides of the movable frame; the other end of the elastic sleeve is fixed to the inner side wall of the bearing plate; the elastic sleeve surrounds the lead screw; through the above structure, it is difficult for external impurities to fall on the lead screw, thereby reducing the occurrence of impurities adhering to the lead screw and increasing the moving resistance of the movable frame when adjusting the position of the movable frame.

[0012] Preferably, the operating lever is made of high-strength metal; the support rod is also made of high-strength metal. With the above structure, the operating lever and the support rod are less likely to bend under force, reducing the inconvenience of adjusting the knob after the operating lever bends, and also reducing the inability to fold and store the support rod after it bends under force.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The battery storage cabinet of this utility model, which facilitates quick replacement of battery packs, allows for quick and convenient replacement of battery packs without the use of forklifts or other devices, by setting up a cabinet, a moving frame, pulleys, cables, a bearing plate, support rods, connecting bolts, and a first insertion hole. This reduces the possibility of structural damage caused by collisions between the forks of forklifts and other devices when the battery packs are being inserted into the cabinet.

[0015] 2. The battery storage cabinet of this utility model, which facilitates quick replacement of battery packs, uses a lead screw, adjusting knob, moving frame, and roller to easily adjust the position of the battery pack when there is a positional deviation when the battery pack is placed on the support plate. This reduces the occurrence of installation obstruction caused by the battery pack conflicting with other components when pushing the battery pack towards the installation position inside the cabinet, further improving the ease of battery pack installation.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 3 As shown in the figure, a battery energy storage cabinet for quick battery pack replacement according to an embodiment of the present invention includes a cabinet 1; a movable frame 12 is slidably connected to the middle of the cabinet 1; a pair of pulleys 13 are rotatably connected to the top of the movable frame 12; a cable 14 is sleeved in the middle of the pair of pulleys 13; a winding mechanism is installed inside the cabinet 1; the end of the cable 14 is connected to the winding mechanism; a bearing plate 15 is rotatably connected to the middle of the movable frame 12; support rods 16 are rotatably connected to both sides of the bearing plate 15; a connecting bolt 17 is threadedly connected to the middle of the support rod 16; a first insertion hole 18 is opened at the bottom of the side wall of the movable frame 12; an adjustment mechanism is installed on the top of the bearing plate 15; the adjustment mechanism includes multiple rollers 23; during operation, the support rods 16 are rotated so that the end of the connecting bolt 17 faces the first insertion hole 18, and then the connecting bolt 17 is rotated to insert the end of the connecting bolt 17 into the first insertion hole 18. The battery pack is inserted into the socket 18, thereby fixing the relative position of the support plate 15 and the moving frame 12. Then, the moving frame 12 is moved to the location of the battery pack to be replaced by the winding mechanism. The battery pack to be replaced is moved from inside the cabinet 1 to the support plate 15. Then, the winding mechanism is restarted to move the battery pack on the support plate 15 to the lowest position and remove it for transfer. Then, the new battery pack is placed on the support plate 15, and the support plate 15 is moved to raise the battery pack to the corresponding height. Then, the battery pack is pushed to move the battery pack to the installation position inside the cabinet 1 by the rolling of multiple rollers 23, thereby completing the replacement of the battery pack. With the above structure, the battery pack can be replaced quickly and conveniently without the use of forklifts or other equipment, reducing the possibility of structural damage caused by the forks of forklifts or other equipment colliding with other components when the battery pack is sent into the cabinet 1.

[0025] like Figures 1 to 4As shown, the adjustment mechanism includes a lead screw 2, an adjustment knob 21, a moving frame 22, and a roller 23. The lead screw 2 is rotatably connected to the middle of the support plate 15; the adjustment knob 21 is fixed to the end of the lead screw 2; the moving frame 22 is threadedly connected to the middle of the adjustment knob 21; the moving frame 22 is slidably connected to the middle of the support plate 15; and the roller 23 is rotatably connected to the middle of the moving frame 22. During operation, after the battery pack to be installed is moved onto the support plate 15, the winding mechanism drives the support plate 15 to move, sending the battery pack to the corresponding height. At this time, the installation height of the battery pack meets the requirements, but the horizontal position of the battery pack may have a certain deviation. At this time, the battery pack is pushed into the cabinet 1. If the battery pack is not properly positioned, the surface of the battery pack may be obstructed and damaged. When there is a deviation in the horizontal position of the battery pack, the adjustment knob 21 can be turned to drive the lead screw 2 to rotate. The rotating lead screw 2 will then move the moving frame 22 on the support plate 15, thereby adjusting the position of the battery pack on the multiple rollers 23 so that the battery pack can be aligned with the installation position. With the above structure, when there is a positional deviation of the battery pack placed on the support plate 15, the position of the battery pack can be easily adjusted. This reduces the occurrence of installation obstruction caused by the battery pack conflicting with other components when pushing the battery pack into the installation position inside the cabinet 1, further improving the ease of installation of the battery pack.

[0026] like Figures 1 to 5 As shown, a limiting rod 3 is rotatably connected to the top of the support plate 15; a movable rod 31 is slidably connected to the middle of the limiting rod 3; a slot 32 is provided in the middle of the support plate 15; during operation, after the battery pack is placed on multiple rollers 23, the limiting rod 3 is rotated so that the limiting rod 3 is perpendicular to the top of the support plate 15. At this time, the movable rod 31 will slide down under the action of gravity, and the bottom end of the movable rod 31 will insert into the slot 32, thereby keeping the limiting rod 3 upright and limiting the battery pack, so that the battery pack will not easily slip during the upward process. After sliding the movable rod 31 upward so that the bottom end of the movable rod 31 disengages from the slot 32, the limiting rod 3 can be rotated again to lay it down. Through the above structure, when the battery pack is moved up and down by the support plate 15, the occurrence of the battery pack slipping due to the rotation of the rollers 23 can be reduced, and the safety of the device can be improved.

[0027] like Figures 1 to 2As shown, the side wall of the movable frame 12 has a second insertion hole 4; the side wall of the support plate 15 has a third insertion hole 41. During operation, after the battery pack is replaced, the active connecting bolt 17 is used to move the connecting bolt 17 away from the support rod 16 and the first insertion hole 18. Then, the support plate 15 and the support rod 16 are rotated so that the second insertion hole 4, the third insertion hole 41 and the threaded hole on the support rod 16 are aligned. Then, the connecting bolt 17 is inserted from the third insertion hole 41 and rotated so that the end of the connecting bolt 17 extends into the second insertion hole 4. This allows the support plate 15 and the support rod 16 to be stored in the middle of the screw 2 to form a plate shape, reducing the space occupied by the components. With the above structure, after the battery pack is replaced, the support plate 15 and the support rod 16 can be folded and their position restricted. Then, the support plate 15 and the support rod 16 can be moved to a height with less obstruction, reducing the space occupied by the energy storage cabinet and reducing the obstruction to the daily use of the energy storage cabinet, thus improving the ease of use of the device.

[0028] like Figures 1 to 3 As shown, the adjustment knob 21 has multiple through holes 5 arranged in a circular array in its center; an operating rod 51 is detachably installed in the center of each through hole 5; a mounting groove 52 is provided on the side wall of the support plate 15; a buckle 53 is fixedly connected to the inner side wall of the mounting groove 52; during operation, when it is necessary to rotate the adjustment knob 21 to adjust the position of the moving frame 22, the operating rod 51 can be inserted into the through hole 5 and then rotated, thereby increasing the rotation torque of the adjustment knob 21, making the rotation of the adjustment knob 21 more efficient. To save effort, after use, the operating lever 51 is placed into the storage slot 52 and secured with the buckle 53, making it difficult to lose. Furthermore, when the adjustment knob 21 needs to be turned later, there is no need to search for additional tools. This structure reduces rotational resistance when turning the adjustment knob 21 and allows the operating tools to be directly stored in the storage slot 52, thus improving the ease of use of the device and eliminating the need to search for suitable tools later.

[0029] like Figures 1 to 4 As shown, elastic sleeves 6 are fixed to both sides of the movable frame 22; the other end of the elastic sleeve 6 is fixed to the inner side wall of the bearing plate 15; the elastic sleeve 6 surrounds the lead screw 2; through the above structure, it is difficult for external impurities to fall on the lead screw 2, thereby reducing the occurrence of impurities adhering to the lead screw 2 and increasing the moving resistance of the movable frame 22 when adjusting the position of the movable frame 22.

[0030] like Figure 2As shown, the operating lever 51 is made of high-strength metal; the support rod 16 is also made of high-strength metal. Through the above structure, the operating lever 51 and the support rod 16 are less likely to be bent by force, reducing the inconvenience of adjusting the knob 21 after the operating lever 51 is bent, and also reducing the situation where the support rod 16 cannot be folded and stored after being bent by force.

[0031] During operation, the support rod 16 is rotated so that the end of the connecting bolt 17 faces the first insertion hole 18. Then, the connecting bolt 17 is rotated to insert the end of the connecting bolt 17 into the first insertion hole 18, thereby fixing the relative position of the support plate 15 and the moving frame 12. Then, the moving frame 12 is moved to the location of the battery pack to be replaced by the winding mechanism. The battery pack to be replaced is moved from inside the cabinet 1 onto the support plate 15. Then, the winding mechanism is restarted to move the battery pack on the support plate 15 to the lowest position and remove it for transfer. Then, the new battery pack is placed on the support plate 15, and the support plate 15 is moved to raise the battery pack to the corresponding height. Then, the battery pack is pushed to move the battery pack into the cabinet 1 by the rolling of multiple rollers 23. The battery pack is then positioned to complete the replacement. After the battery pack to be installed is moved onto the support plate 15, the winding mechanism moves the support plate 15 to the corresponding height, ensuring the battery pack is at the required installation height. However, there may be some deviation in the horizontal position of the battery pack. Pushing the battery pack into the cabinet 1 at this time could easily cause damage to the surface of the battery pack due to obstruction. When there is a deviation in the horizontal position of the battery pack, the adjustment knob 21 can be turned to rotate the lead screw 2. The rotating lead screw 2 will then move the moving frame 22 on the support plate 15, thereby adjusting the position of the battery pack on the multiple rollers 23 so that the battery pack can be aligned with the installation position. The battery pack is then placed on the multiple rollers 23. Then, rotate the limiting rod 3 so that it is perpendicular to the top of the support plate 15. At this time, the movable rod 31 will slide down under the action of gravity, and the bottom end of the movable rod 31 will insert into the slot 32, thereby keeping the limiting rod 3 upright and limiting the battery pack, so that the battery pack will not easily slip during the upward process. After sliding the movable rod 31 upward so that the bottom end of the movable rod 31 disengages from the slot 32, the limiting rod 3 can be rotated again to lay it down. After the battery pack replacement is completed, the active connecting bolt 17 is used to move the connecting bolt 17 away from the support rod 16 and the first insertion hole 18. Then, the support plate 15 and the support rod 16 are rotated so that the second insertion hole 4, the third insertion hole 41 and the threaded hole on the support rod 16 are aligned. Then, the connecting bolt 17 is moved from the first insertion hole 16 to the second insertion hole 4 and the third insertion hole 41. Insert and rotate the three-hole 41 so that the end of the connecting bolt 17 extends into the second hole 4, thereby allowing the bearing plate 15 and the support rod 16 to be housed in the middle of the screw 2 to form a plate shape, reducing the space occupied by the components. When it is necessary to rotate the adjustment knob 21 to adjust the position of the moving frame 22, the operating rod 51 can be inserted into the through hole 5 and then rotated. The operating rod 51 increases the torque of the adjustment knob 21, making the rotation of the adjustment knob 21 easier. After use, the operating rod 51 is placed in the placement slot 52 and the operating rod 51 is clamped and fixed by the buckle 53, making the operating rod 51 difficult to lose and eliminating the need to find additional tools when the adjustment knob 21 needs to be rotated later.
