[0010] Preferably, the cams are distributed on the vertical rod at equal intervals, and the vertical rod is connected to the transmission rod through a second belt transmission structure.

[0011] Preferably, the sliding plate on one side of the cam is slidably connected to the inner top of the top plate, and the top plate is rotatably connected to the vertical rod.

[0016] Preferably, the soot blowing pipes are distributed on the inner wall of the inspection door at equal intervals, and the soot blowing pipes are arranged corresponding to the battery packs.

[0017] Compared with the prior art, the invention has the following beneficial effects: the power battery structure frame is easy to maintain.

[0018] (1) The present invention can effectively solve the problem that most of the existing power battery structure frames are fixed in structure, so that the storage and installation position of the battery pack is fixed, which makes it inconvenient to inspect and maintain them through the coordinated use of the motor, the rotating shaft and the transmission rod. The motor drives the transmission rod at the bottom to rotate. When the transmission rod rotates, the second gear plate drives the first gear plate and the transmission rod inside it to rotate. When the two sets of transmission rods rotate, they will drive the rotating shaft outside them through the first belt transmission structure to drive the moving seat at the bottom of the first rotating frame and the second rotating frame to rotate synchronously outward until the battery pack inside is exposed and is in contact with the battery pack on the inner wall of the fixed seat. On the same horizontal line, the battery packs are prevented from blocking each other and affecting the maintenance work. At the same time, the staff can rotate and open the maintenance door according to the maintenance needs, so as to facilitate the maintenance of the battery packs installed on the inner mounting plate of the mobile seat from different angles, thereby improving the maintenance efficiency of the device. Compared with the existing method of disassembling the outer battery pack to maintain the inner blocked battery pack, it is more convenient, and after the maintenance, the staff can control the motor to rotate in the reverse direction to reset the mobile seat. After the reset, the battery pack on the mobile seat and the battery pack on the fixed seat are gathered together, thereby saving storage space and facilitating the overall heat dissipation;

[0019] (2) The present invention can effectively solve the problem that the existing power battery structure frame usually needs to be manually cleaned of dust on its surface during inspection and maintenance, thereby affecting the inspection and maintenance efficiency. When the mobile seat rotates to unfold the battery pack inside it, the airbag will be squeezed. After the airbag is compressed, the gas inside it will be discharged through the one-way exhaust valve and temporarily stored in the telescopic pipe. Then the staff can open the corresponding electric valve according to the battery inspection and maintenance position, so that the gas stored in the telescopic pipe is discharged through the soot blowing pipe at the corresponding position to blow and clean the batteries that have failed and are to be inspected. Compared with the manual dust cleaning method, it is more convenient and does not require additional driving equipment, that is, it reduces the energy consumption of the device while ensuring the function. Similarly, when the mobile seat rotates away from the airbag, the airbag will automatically deform and stretch so that the external airflow enters its interior through the one-way air intake valve, that is, the automatic inflation of the airbag is realized to provide dust blowing power for the next power battery inspection and maintenance work;

[0020] (3) The present invention can effectively solve the problem of the sootblowing position of the existing power battery structure frame sootblowing mechanism being single and unable to take into account all battery packs, thus easily resulting in sootblowing dead angles, by using a reciprocating sootblowing mechanism and a second belt transmission structure in conjunction with each other. The motor drives the transmission rod to drive the first rotating frame and the second rotating frame to rotate to display the battery pack, and at the same time drives the vertical rod through the second belt transmission structure to drive the multiple groups of cams connected above it to rotate. When the convex point of the cam rotates and contacts the sliding plate, the sliding plate will squeeze the balloon, and the gas inside the balloon will enter the interior of the fixed seat through the pipeline and be discharged through the sootblowing port on the side wall of the fixed seat. At the same time, since there is a certain gap between the sootblowing port and the battery pack on the mounting plate, the gas discharged from the sootblowing port will be radially sprayed toward the battery pack, that is, the sootblowing range of the battery pack is expanded to the greatest extent, thereby improving the cleaning effect.

[0033] In a further embodiment, the reciprocating sootblowing mechanism 11 includes a vertical rod 1101, a cam 1102, a sliding plate 1103 and a balloon 1104, and the cam 1102 is connected to the vertical rod 1101, a sliding plate 1103 is arranged on one side of the cam 1102, and two groups of sliding plates 1103 are arranged, and the sliding plates 1103 are connected by the balloon 1104, and the balloon 1104 is connected to the sootblowing port 24 through a pipe, and the sootblowing port 24 is opened on the inner wall of the fixed seat 1.

[0034] In a further embodiment, the cams 1102 are distributed on the vertical rod 1101 at equal intervals, and the vertical rod 1101 is connected to the transmission rod 5 via the second belt transmission structure 9 .

[0035] In a further embodiment, the sliding plate 1103 on one side of the cam 1102 is slidably connected to the inner top of the top plate 15 , and the top plate 15 is rotatably connected to the vertical rod 1101 .

[0036] In a further embodiment, the moving directions of the first rack 12 and the second rack 13 are opposite, and the first rack 12 is arranged above the second rack 13, and the bottoms of the first rack 12, the second rack 13 and the dustproof plate 16 are all connected to the lighting lamp 14.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the first magnet block 17 is arranged on the top of the first rotating frame 3 and the second rotating frame 4, and the bottom of the first rotating frame 3 and the second rotating frame 4 are connected to a movable seat 19, the inner side walls of the movable seat 19 and the fixed seat 1 are provided with a mounting plate 20, and a battery pack is installed on the mounting plate 20, the movable seat 19 is connected to a mobile soot blowing mechanism 23, and the mobile soot blowing mechanism 23 is symmetrically arranged in two groups.

[0038] In a further embodiment, the first magnet block 17 is magnetically connected to the second magnet block 18 , and the second magnet block 18 is correspondingly distributed at the bottom of the dustproof plate 16 .

[0039] In a further embodiment, an inspection door 21 is rotatably connected to the movable seat 19 , and spheres 22 are arranged at equal intervals on the bottom of the movable seat 19 .

[0040] Specifically, in the actual working process, the battery pack is installed on the mounting plate 20 on the inner wall of the movable seat 19 and the fixed seat 1, and the external heat dissipation mechanism centrally dissipates the heat for the batteries on the movable seat 19 and the fixed seat 1. When the battery needs to be inspected and maintained, the staff can remove the parts around the device, and then start the device. The motor 10 drives the transmission rod 5 at the bottom thereof to rotate. When the transmission rod 5 rotates, the first gear plate 6 and the transmission rod 5 inside thereof are pushed to rotate through the second gear plate 7. When the two sets of transmission rods 5 rotate, they will drive the rotating shaft 2 outside thereof through the first belt transmission structure 8 to drive the movable seat 19 at the bottom of the first rotating frame 3 and the second rotating frame 4 to rotate synchronously outward until the battery pack inside thereof is exposed and is on the same horizontal line with the battery pack on the inner wall of the fixed seat 1, so as to avoid the battery packs blocking each other and affecting the maintenance work. The lighting lamp 14 provides lighting for the maintenance work. At the same time, the staff can rotate and open the maintenance door 21 according to the maintenance needs, so as to facilitate the maintenance of the battery pack installed on the mounting plate 20 inside the movable seat 19 from different angles.

[0041] On the other hand, when the first gear disc 6 and the second gear disc 7 rotate, they will push the first rack 12 and the second rack 13 on the rear side thereof to drive the lighting lamp 14 to extend to both sides to provide lighting for the staff to carry out maintenance work through the maintenance door 21. In addition, when the movable seat 19 rotates to display the battery pack, it will squeeze the airbag 2302. After the airbag 2302 is pressurized, the gas inside it will be discharged through the one-way exhaust valve 2305 and temporarily stored in the telescopic pipe 2304. Then, the staff can open the corresponding electric valve 2306 according to the needs of the battery maintenance position, so that the gas stored in the telescopic pipe 2304 can be discharged through the soot blowing pipe 2307 at the corresponding position to blow and clean the batteries that have failed and are to be repaired. Similarly, when the movable seat 19 rotates away from the airbag 2302, the airbag 2302 will automatically deform and stretch to allow the external airflow to enter its interior through the one-way air inlet valve 2303, thereby realizing the automatic inflation of the airbag 2302.

[0042] When the motor 10 drives the transmission rod 5 to drive the first rotating frame 3 and the second rotating frame 4 to rotate and display the battery pack, the vertical rod 1101 will be driven by the second belt transmission structure 9 to drive the multiple groups of cams 1102 connected above it to rotate. When the convex point of the cam 1102 rotates and contacts the sliding plate 1103, the sliding plate 1103 will squeeze the balloon 1104, and the gas inside the balloon 1104 will enter the interior of the fixed seat 1 through the pipeline, and be radially discharged through the soot blowing port 24 on the side wall of the fixed seat 1 to clean the battery pack, that is, to maximize the soot blowing range of the battery pack. After cleaning, the motor 10 is controlled to rotate in the opposite direction to reset the movable seat 19. The sphere 22 plays an auxiliary supporting role while the movable seat 19 moves and resets, thereby improving its stability during rotation. After the reset, the first magnet block 17 at the top of the movable seat 19 is magnetically connected to the second magnet block 18 at the bottom of the dustproof plate 16, that is, the purpose of limiting is achieved.

[0046] In a further embodiment, the soot blowing pipes 2307 are distributed on the inner wall of the inspection door 21 at equal intervals, and the soot blowing pipes 2307 are arranged corresponding to the battery packs.

[0047] Specifically, when the movable seat 19 rotates to display the battery pack, the airbag 2302 will be squeezed. After the airbag 2302 is pressurized, the gas inside it will be discharged through the one-way exhaust valve 2305 and temporarily stored in the telescopic pipe 2304.
