TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic, in particular to a photovoltaic storage battery mounting seat convenient to hang. BACKGROUND

[0002] In order to save energy and utilize the energy in the natural environment, more and more people use photovoltaic power generation. Photovoltaic power generation is a power generation system that converts solar radiation into electric energy. The electric energy converted from solar energy is usually stored in a storage battery pack. The storage battery pack usually contains a plurality of storage batteries. In use, the storage batteries are usually installed on corresponding mounting seats to maintain the stability of the storage batteries during use.

[0003] However, the mounting seats on the market are usually directly placed on the ground for use, which occupies a large space on the ground and brings inconvenience to the user. SUMMARY

[0004] In order to improve the problem that the mounting seat is directly placed on the ground for use and occupies a large space, the present application provides a photovoltaic storage battery mounting seat convenient to hang.

[0005] The photovoltaic storage battery mounting seat convenient to hang provided by the present application adopts the following technical solution:

[0006] The photovoltaic storage battery mounting seat convenient to hang comprises a mounting rack for mounting storage batteries, a hanging plate, and a lifting device for controlling the lifting of the mounting rack. The hanging plate comprises a fixed plate and a movable plate hinged to the bottom of the fixed plate. The mounting rack is in sliding cooperation with the fixed plate. The output end of the lifting device is connected to the mounting rack. The angle between the movable plate and the fixed plate is an acute angle. The end of the movable plate away from the hinge is detachably connected to the mounting rack.

[0007] By adopting the above technical solution, the storage batteries in the storage battery pack are placed on the mounting rack. The lifting device is started. The lifting device drives the mounting rack to move away from the ground. The mounting rack and the storage batteries on the mounting rack are moved to a high place. Then the movable plate is rotated. The end of the movable plate away from the hinge is connected to the bottom of the mounting rack. A triangle is formed between the bottom of the mounting rack, the movable plate, and the fixed plate. Thus, the mounting rack is supported, and the stability of the mounting rack is improved. Compared with directly placing the mounting rack on the ground for use, space is saved. The problem that the mounting seat is directly placed on the ground for use and occupies a large space, which brings inconvenience to the user, is improved.

[0008] Optionally, the mounting rack comprises a frame and a rack plate for placing the storage battery, the frame is in sliding fit with the fixing plate, the lifting device is connected with the frame, the rack plate is in sliding connection in the frame, the adjacent rack plates are arranged at intervals, and a baffle for shielding the storage battery and preventing the storage battery from falling off is detachably connected on the frame, and the baffle is provided with heat dissipation holes.

[0009] By adopting the above technical scheme, when the storage battery is installed, the rack plate is pulled out from the frame, the storage battery can be placed on the rack plate from the outside of the frame, and the installation of the storage battery is facilitated. After the storage battery is installed on the rack plate, the rack plate is pushed, and the rack plate and the storage battery are pushed into the frame. The baffle can protect the storage battery and prevent the storage battery from falling off. The heat generated during the operation of the storage battery can be discharged through the heat dissipation holes, so that the heat accumulation around the storage battery is avoided, and the service life of the storage battery is affected.

[0010] Optionally, the baffle is arranged in a U shape, the baffle shields the frame around in cooperation with the fixing plate, the baffle is connected with a first motor, a heat dissipation mechanism and an axle group, the heat dissipation mechanism comprises a chain wheel, a chain and a fan, the axle group comprises two transmission shafts, the transmission shafts are rotatably connected at two ends in the vertical direction of the baffle, the first motor is arranged on the baffle and is linked with the transmission shafts, the chain wheel is arranged on the transmission shaft, the chain is sleeved on the chain wheel, and the fan is connected with the chain.

[0011] By adopting the above technical scheme, the first motor and the fan are started, the first motor drives the chain wheel to rotate through the transmission shaft, so as to drive the chain to move. The chain drives the fan to move in the moving process. The fan can achieve the purpose of heat dissipation faster. The fan is in a moving state. By controlling the forward and reverse rotation of the first motor, the fan can reciprocate. Compared with the heat dissipation of the fan fixed at a position, the heat dissipation is more uniform, and the heat dissipation effect is better.

[0012] Optionally, one axle group and at least one heat dissipation mechanism are arranged on each side wall of the baffle, the axle groups share one first motor, and the first motor is connected with one transmission shaft; the transmission shafts on the adjacent side walls of the baffle are perpendicular to each other, and a steering structure is connected between the transmission shafts on the adjacent side walls of the baffle, the steering structure comprises steering plates and L-shaped steering rods, the steering plates are arranged in two, the steering plates are connected on the transmission shafts on the adjacent side walls of the baffle, the center lines of the two steering plates are perpendicular to each other, and the steering plates are provided with transmission holes; one branch of the L-shaped steering rod passes through one steering plate through the transmission hole and is parallel to the transmission shaft of the steering plate; the other branch of the L-shaped steering rod passes through the other steering plate through the transmission hole and is parallel to the transmission shaft of the steering plate.

[0013] By adopting the above technical solution, firstly, a shaft group and at least one heat dissipation mechanism are provided on each side wall of the baffle, so that there is at least one fan on each side wall of the baffle, which further improves the heat dissipation effect. Secondly, the shaft groups share a first motor, which can achieve the purpose of energy saving. Thirdly, since the drive shafts on adjacent side walls of the baffle are connected by a steering structure, during the rotation of one drive shaft, the drive shaft drives the steering plate connected to it to rotate. During the rotation of the steering plate, the steering plate drives another steering plate in the steering structure to rotate through the L-shaped steering rod, thereby achieving the purpose of driving the drive shafts on adjacent side walls of the baffle to rotate. Compared with traditional steering structures (such as bevel gear sets), the steering structure is simple in structure and low in cost. Moreover, the steering structure will not wear during the steering process and has a long service life. Unlike bevel gear sets, the bevel gears will not wear after long-term use.

[0014] Optionally, the fan is connected to a connecting ear, and a guide post is connected to the baffle. The connecting ear is penetrated by the guide post, and the connecting ear and the guide post are slidably engaged.

[0015] By adopting the above technical solution, the connecting ear moves along the guide post during the fan's movement, thereby guiding the fan's movement direction and improving the fan's stability during movement.

[0016] Optionally, the frame plate is provided with a plurality of mounting holes, and a limiting post is slidably connected in the mounting holes. A first spring is connected between the limiting post and the bottom of the mounting hole. When the first spring is in its natural state, one end of the limiting post is located inside the mounting hole and the other end is located outside the mounting hole.

[0017] By adopting the above technical solution, on the one hand, when installing the battery, placing the battery on the rack will cause the weight of the battery to press down the limiting post located below the battery, while the limiting posts around the battery will remain in their original state. The limiting posts around the battery can limit the battery and prevent it from shifting significantly under external force. On the other hand, each limiting post on the rack can be pressed down under external force. Therefore, the limiting posts on the rack can limit batteries of different sizes, making it widely applicable.

[0018] Optionally, one end of the mounting bracket is provided with a dovetail groove, and the other end is provided with a dovetail strip that matches the dovetail groove. Between adjacent mounting brackets, the dovetail strip on the lower mounting bracket is inserted into the dovetail groove on the higher mounting bracket, and the mounting bracket is provided with a locking device to prevent the dovetail strip from dislodging from the dovetail groove. The movable plate is detachably connected to the lower mounting bracket in the mounting bracket.

[0019] By adopting the above technical solution, the dovetail strip and dovetail groove can be set to enable splicing between two adjacent mounting brackets, so that more mounting brackets can be assembled together, making it convenient to install more batteries. The locking part can limit the dovetail strip and prevent it from detaching from the dovetail groove. The movable plate is connected to the mounting bracket below and can support the spliced ​​mounting brackets to improve the stability of the spliced ​​mounting brackets.

[0020] Optionally, the locking component includes a center block, a locking rod, a lever, a connecting rod, an arc-shaped strip, a clamping rod, and a second spring. The center block is hinged to the mounting bracket. The locking rod, lever, and connecting rod are all connected to the center block. The connecting rod is located between the locking rod and the lever. One end of the arc-shaped strip is connected to the locking rod, and the other end is connected to the connecting rod. The end of the connecting rod away from the center block protrudes from the end of the arc-shaped strip away from the center block. The arc-shaped strip has a locking groove. The clamping rod is hinged to the mounting bracket and bent towards the end of the locking rod. One end of the second spring is connected to the lever plate, and the other end is connected to the mounting base. The second spring is located on the side of the connecting rod away from the locking rod. When the bent part of the clamping rod is inserted into the locking groove, the second spring is stretched. At this time, the locking rod is located on one side of the dovetail groove, and the locking component is in the unlocked state. When the locking rod blocks the dovetail strip, the bent part of the clamping rod disengages from the locking groove and abuts against the connecting rod, and the second spring returns from the stretched state to the initial state.

[0021] By adopting the above technical solution, when it is necessary to lock the dovetail strip, the locking rod is rotated to disengage the bent part of the locking rod from the locking groove. At this time, the positioning of the locking rod, the arc strip, the connecting rod, and the lever is released, and the second spring changes from a stretched state to a free state. During this process, the lever rotates, thereby causing the center block, the locking rod, the arc strip, and the connecting rod to rotate. The locking rod rotates to the opening of the dovetail groove and blocks the dovetail strip. The bent part of the locking rod moves relative to the arc strip. When the bent part of the locking rod... When the connecting rod protrudes from the arc-shaped strip, the locking rod stops rotating, thus locking the dovetail strip. When it is necessary to unlock the dovetail strip, the lever is moved, and the locking rod, arc-shaped strip, and connecting rod rotate. The locking rod rotates to one side of the dovetail groove. During this process, the second spring is gradually stretched, and the bent part of the locking rod slides along the arc-shaped strip until the bent part of the locking rod is inserted into the locking groove. At this time, the locking rod is positioned on one side of the dovetail groove to prevent the locking rod from rotating again, thus unlocking the dovetail strip.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Place the batteries from the battery pack on the mounting bracket, start the lifting device, and the lifting device will move the mounting bracket away from the ground, moving the mounting bracket and the batteries on the mounting bracket to a higher position. Then rotate the movable plate so that the end of the movable plate away from the hinge is connected to the bottom of the mounting bracket. The bottom of the mounting bracket, the movable plate and the fixed plate form a triangle, which supports the mounting bracket and improves the stability of the mounting bracket. At this time, the mounting bracket is off the ground. Compared with the mounting bracket being placed directly on the ground, it saves space and improves the problem of the mounting bracket occupying a lot of space and causing inconvenience to users.

[0024] 2. Firstly, each side wall of the baffle is equipped with a shaft assembly and at least one heat dissipation mechanism, thereby ensuring that each side wall of the baffle has at least one fan, further improving the heat dissipation effect. Secondly, the shaft assemblies share a common first motor, achieving energy saving. Thirdly, since the drive shafts on adjacent side walls of the baffle are connected by a steering structure, during the rotation of one drive shaft, the drive shaft drives the steering plate connected to it to rotate. During the rotation of the steering plate, the steering plate drives another steering plate in the steering structure to rotate through the L-shaped steering rod, thereby achieving the purpose of driving the drive shafts on adjacent side walls of the baffle to rotate. Compared with traditional steering structures (such as bevel gear sets), the steering structure is simple in structure, low in cost, and does not wear during the steering process, resulting in a long service life. Unlike bevel gear sets, the bevel gears do not wear after long-term use.

[0025] 3. On the one hand, when installing the battery, placing it on the rack will cause the weight of the battery to press down on the limiting post located below the battery, while the limiting posts around the battery will remain in their original state. The limiting posts around the battery can limit the battery and prevent it from shifting significantly under external force. On the other hand, each limiting post on the rack can be pressed down under external force. Therefore, the limiting posts on the rack can limit batteries of different sizes, making it widely applicable. Attached Figure Description

[0037] This application discloses a mounting bracket for photovoltaic battery packs that is easy to mount.

[0038] Reference Figure 1 A photovoltaic battery pack mounting base that is easy to mount includes a mounting frame, a mounting plate, and a lifting device for controlling the raising and lowering of the mounting frame.

[0039] Reference Figure 1 The mounting plate includes a fixed plate 2 and a movable plate 3. The fixed plate 2 is fixedly connected to the wall 45, and the movable plate 3 is hinged to the bottom of the fixed plate 2. The mounting bracket is slidably engaged with the fixed plate 2.

[0040] Reference Figure 1 and Figure 2 The mounting bracket is used to install the storage battery 1. The mounting bracket includes a frame 46 and two bracket plates 47 for placing the storage battery 1. The frame 46 is slidably engaged with the fixed plate 2. The fixed plate 2 is provided with a sliding groove 4. The sliding groove 4 is set along the length direction of the fixed plate 2 and passes through the fixed plate 2. A sliding strip 5 is connected to the frame 46. The sliding strip 5 is slidably inserted into the sliding groove 4 and slidably engaged with the sliding groove 4. The cross-section of the sliding strip 5 and the sliding groove 4 are both dovetail shaped.

[0041] Reference Figure 1 , Figure 2 and Figure 3 One end of the frame 46 is provided with a dovetail groove 6, and the other end is provided with a dovetail strip 7 that matches the dovetail groove 6. Between adjacent mounting frames, the dovetail strip 7 on the lower mounting frame is inserted into the dovetail groove 6 on the higher mounting frame. The end of the dovetail groove 6 near the fixing plate 2 is connected to a sealing block 8, and the side of the mounting frame away from the sealing block 8 is connected to a locking member to prevent the dovetail strip 7 from disengaging from the dovetail groove 6. In this embodiment, two mounting frames are provided.

[0042] Reference Figure 4 The locking components include a center block 9, a locking rod 10, a lever 11, a connecting rod 12, an arc-shaped strip 13, a clamping rod 14, and a second spring 15.

[0043] Reference Figure 1 and Figure 4The center block 9 is hinged to the frame 46 by a pin. The locking rod 10, the lever 11, and the connecting rod 12 are all connected to the center block 9. The end of the lever 11 away from the center block 9 is connected to a second wrench 16. The locking rod 10, the lever 11, and the connecting rod 12 are all integrally formed with the center block 9. The connecting rod 12 is located between the locking rod 10 and the lever 11. One end of the arc-shaped strip 13 is connected to the locking rod 10, and the other end is connected to the connecting rod 12. The arc-shaped strip 13 is integrally formed with the locking rod 10. The connecting rod 12 and the locking rod 13 are integrally formed. The end of the connecting rod 12 away from the center block 9 protrudes from the side of the arc-shaped strip 13 away from the center block 9. The end of the locking rod 10 away from the center block 9 protrudes from the side of the arc-shaped strip 13 away from the center block 9. The arc-shaped strip 13 is provided with a locking groove 17 at the end near the locking rod 10. In this embodiment, in a complete locking groove 17, a part of the locking groove 17 is opened on the arc-shaped strip 13, and the other part of the locking groove 17 is opened on the side of the locking rod 10 near the arc-shaped strip 13. The locking rod 14 is hinged to the frame 46. One end of the locking rod 14 is bent toward the locking rod 10, and the other end is connected to the first wrench 18. A connecting bolt 19 is connected to the frame 46. One end of the second spring 15 is connected to the lever plate, and the other end is connected to the connecting bolt 19. The second spring 15 is located on the side of the connecting rod 12 away from the locking rod 10. When the bent part of the locking rod 14 is inserted into the locking groove 17, the second spring 15 is stretched. At this time, the locking rod 10 is located on one side of the dovetail groove 6, the locking element is in the unlocked state, and the locking rod 10 no longer covers the dovetail strip 7. When the locking rod 10 covers the dovetail strip 7, the bent part of the locking rod 14 disengages from the locking groove 17 and abuts against the connecting rod 12. The second spring 15 returns from the stretched state to the initial state.

[0044] When connecting two mounting brackets, first turn the second wrench 16. The center block 9, locking rod 10, connecting rod 12, arc-shaped strip 13, and lever 11 all rotate. The locking rod 10 rotates to one side of the dovetail groove 6, clearing the opening of the dovetail groove 6. At this time, the second spring 15 is stretched. During the movement of the arc-shaped strip 13, the relative position between the arc-shaped strip 13 and the bent part on the clamping rod 14 changes continuously until the bent part of the clamping rod 14 is inserted into the locking groove 17, thereby locking the locking rod 10 and preventing the locking rod 10 from obstructing the dovetail groove 6 again. Then, insert the dovetail strip 7 from one mounting bracket into the dovetail groove 6 of the other mounting bracket, so that the dovetail strip 7 abuts against the sealing block 8 in the dovetail groove 6. Rotating the first wrench 18 causes the clamping rod 14 to rotate, disengaging the bent portion of the clamping rod 14 from the locking groove 17. At this time, the second spring 15 changes from a stretched state to its initial state. The lever 11 rotates under the elastic force of the second spring 15, causing the center block 9, the locking rod 10, the connecting rod 12, and the arc-shaped strip 13 to rotate. The locking rod 10 rotates to the opening of the dovetail groove 6. During the rotation of the arc-shaped strip 13, the relative position between the arc-shaped strip 13 and the bent portion of the clamping rod 14 changes continuously until the bent portion of the clamping rod 14 abuts against the connecting rod 12, thereby positioning the locking rod 10 and preventing the locking rod 10 from rotating excessively, thus achieving the connection between the two mounting brackets.

[0045] Reference Figure 1 , Figure 2 and Figure 5 The shelf 47 is horizontally slidably connected to the frame 46. Adjacent shelf 47s are spaced apart. Slide rails 20 are connected to two opposite side walls inside the frame 46. Slide strips 21 are connected to the shelf 47. Slide strips 21 are slidably inserted into the slide rails 20. A limit block 48 is connected to the side of the slide rail 20 facing the fixed plate 2 to limit the slide strips 21 and prevent the slide strips 21 from popping out from the other end of the slide rail 20 during the insertion process.

[0046] Reference Figure 2 and Figure 6 The frame plate 47 has several mounting holes 22 arranged in a rectangular array. Limiting posts 24 are slidably connected within each mounting hole 22. A first spring 23 connects the limiting post 24 to the bottom of the mounting hole 22. When the first spring 23 is in its natural state, one end of the limiting post 24 is inside the mounting hole 22, and the other end is outside. When the battery 1 is placed on the frame plate 47, the limiting posts 24 below the frame plate 47 are pressed down into the mounting holes 22, and the limiting posts 24 around the battery 1 can limit its movement.

[0047] Reference Figure 1 and Figure 2A baffle 25 is detachably connected to the frame 46 by screws. The baffle 25 can cover the battery 1 to prevent the battery 1 from falling. The baffle 25 is U-shaped and covers the three sides of the frame 46 except the side facing the fixed plate 2. The baffle 25 cooperates with the fixed plate 2 to cover the frame 46 from all sides. The baffle 25 is provided with heat dissipation holes 26 so that the battery 1 can dissipate heat.

[0048] Reference Figure 1 The baffle 25 is connected to a first motor 27, a heat dissipation mechanism, and a shaft assembly. Each side wall of the baffle 25 is provided with a shaft assembly and at least one heat dissipation mechanism. In this embodiment, two heat dissipation mechanisms are provided on the side wall of the baffle 25 opposite to the fixed plate 2, and one heat dissipation mechanism is provided on each of the other two side walls of the baffle 25. The first motor 27 is set to one, and the shaft assemblies share one first motor 27.

[0049] Reference Figure 1 , Figure 7 and Figure 8 The shaft assembly includes two drive shafts 28, which are rotatably connected to the two ends of the baffle 25 in the vertical direction. The first motor 27 is connected to one of the drive shafts 28. The drive shafts 28 on adjacent side walls of the baffle 25 are perpendicular to each other. A steering structure is connected between the drive shafts 28 on adjacent side walls of the baffle 25. The steering structure includes a steering plate 29 and an L-shaped steering rod 30. There are two steering plates 29, which are connected to the drive shafts 28 on adjacent side walls of the baffle 25. The center lines of the two steering plates 29 are perpendicular to each other, and the center line of the steering plate 29 coincides with the center line of the drive shaft 28 on which the steering plate 29 is located. The steering plate 29 is provided with a transmission hole. One branch of the L-shaped steering rod 30 passes through the transmission hole through one steering plate 29 and is parallel to the drive shaft 28 on which the steering plate 29 is located. The other branch of the L-shaped steering rod 30 passes through the transmission hole through the other steering plate 29 and is parallel to the drive shaft 28 on which the steering plate 29 is located.

[0050] Reference Figure 7 The heat dissipation mechanism includes a sprocket 31, a chain 32, and a fan 33. The sprocket 31 is mounted on two drive shafts 28. One end of the chain 32 is connected to the top of the fan 33, and the other end is connected to the bottom of the fan 33. The chain 32 and the fan 33 form a closed state. The chain 32 is sleeved on the sprocket 31. A connecting ear 34 is connected to the fan 33. A guide post 35 is connected to the baffle 25. The connecting ear 34 is penetrated by the guide post 35. The connecting ear 34 and the guide post 35 slide together to guide the movement direction of the fan 33.

[0051] The first motor 27 is started, which drives the transmission shaft 28 to rotate. Since the transmission shaft 28 on the adjacent side walls of the baffle 25 is connected by a steering structure, during the rotation of the transmission shaft 28 connected to the first motor 27, the transmission shaft 28 drives the steering plate 29 connected to it to rotate. During the rotation of the steering plate 29, the steering plate 29 drives another steering plate 29 in the steering structure to rotate through the L-shaped steering rod 30. The relative position between the L-shaped steering rod 30 and the steering plate 29 changes continuously, thereby achieving the purpose of driving the transmission shaft 28 on the adjacent side walls of the baffle 25 to rotate. Therefore, the shaft groups on the three side walls of the baffle 25 achieve synchronous rotation through the steering structure, and only one first motor 27 drives them, achieving the purpose of energy saving. The steering structure replaces the traditional steering structure (bevel gear set), which is simple in structure, low in manufacturing cost, and long in service life.

[0052] During the rotation of the drive shaft 28, the drive shaft 28 drives the sprocket 31 to rotate, thereby driving the chain 32 and the fan 33 to move. By controlling the forward and reverse rotation of the first motor 27, the fan 33 can move back and forth. During the movement of the fan 33, the fan 33 can accelerate heat dissipation and quickly dissipate the heat generated by the battery 1.

[0053] Reference Figure 1 and Figure 9 The lifting device is embedded in the wall 45 and located above the fixed plate 2. The output end of the lifting device is connected to the frame 46. The lifting device includes a mounting box 36, a second motor 37, a winding shaft 38, a winding reel 39, a winding rope 40, a hook 41, a lifting ring 42, and a connecting rope 43.

[0054] Reference Figure 1 and Figure 9 The mounting box 36 is embedded in the wall 45. The second motor 37 is installed in the mounting box 36. The winding shaft 38 is rotatably connected in the mounting box 36. The second motor 37 is connected to the winding shaft 38. The winding reel 39 is connected to the winding shaft 38. One end of the winding rope 40 is connected to the winding reel 39, and the other end is connected to the hook 41. In the two mounting frames, the top of the upper frame 46 is fixedly connected with connecting ropes 43. All four connecting ropes 43 are connected to the lifting rings 42 in the direction of the center line of the frame 46. The hooks 41 are hooked on the lifting rings 42.

[0055] Reference Figure 1 and Figure 3The bottom of the frame 46 is provided with a snap-fit ​​groove 44, which is connected to the dovetail groove 6. The movable plate 3 is detachably connected to the mounting frame located at the bottom of the mounting frame. Specifically, the end of the movable plate 3 away from the hinge is inserted into the snap-fit ​​groove 44 on the mounting frame located at the bottom of the mounting frame. The angle between the movable plate 3 and the fixed plate 2 is an acute angle. The movable plate 3, the fixed plate 2 and the mounting frame below form a stable triangular structure, which supports the mounting frame in the vertical direction, thereby improving the stability of the mounting frame.

[0056] The implementation principle of the photovoltaic battery pack mounting base of this application embodiment is as follows: In use, the two mounting frames are first spliced ​​together by the cooperation of the dovetail strip 7 and the dovetail groove 6, and then the dovetail strip 7 is locked and limited by the locking component, thereby completing the splicing of the two mounting frames and achieving the purpose of connecting the two mounting frames together.

[0057] After the mounting brackets are connected together, the battery 1 is placed on the bracket plate 47. The limiting post 24 at the bottom of the battery 1 is pressed back into the mounting hole 22. The limiting post 24 around the battery 1 is still in the initial position. The limiting post 24 around the battery 1 limits the battery 1 in order to limit the battery 1.

[0058] After the battery 1 is installed on the bracket 47, the baffle 25 is connected to the frame 46 by screws. The baffle 25 and the limiting post 24 provide double protection for the battery 1.

[0059] After the baffle 25 is installed, the two assembled mounting frames are lifted by a crane. The crane can hook the hook onto the lifting ring 42 and lift the mounting frame to a position higher than the fixed plate 2 in the vertical direction, so that the sliding strip 5 on the frame 46 is above the sliding groove 4 on the fixed plate 2. Then, the sliding strip 5 is lowered so that it is inserted into the sliding groove 4. The mounting frame is lowered to the appropriate position, the movable plate 3 is rotated, and the mounting frame is lowered again so that the movable plate 3 is inserted into the snap-fit ​​groove 44 on the lower mounting frame. Then, the hook 41 on the lifting device is hooked onto the lifting ring 42, and the second motor 37 is started. The second motor 37 drives the winding reel 39 to rotate through the winding shaft 38, winding the connecting rope 43 until the connecting rope 43 is tightened. Then, the hook on the crane is removed. At this time, the installation of the mounting frame is completed. The mounting frame is off the ground. Compared with the mounting frame being placed directly on the ground, it saves space and improves the problem that the mounting base is placed directly on the ground, which occupies a lot of space and causes inconvenience to users.

[0060] During the use of battery 1, the heat generated by battery 1 is discharged through heat dissipation hole 26. At the same time, the first motor 27 and fan 33 are started to realize the reciprocating movement of fan 33. During the movement of fan 33, fan 33 can extract the heat generated by battery 1 more quickly, which is conducive to the rapid heat dissipation of battery 1.
