[0012] Furthermore, an auxiliary mechanism is arranged on the side wall of the protective box body, and the auxiliary mechanism includes a plurality of limit grooves 2 opened on the side wall of the protective box body. Both sides of the protective upper cover are rotatably connected with telescopic rods 2, and one end of the telescopic rods 2 away from the protective upper cover is sleeved with a tension spring 2.

[0014] The protection method of the protection device for the wind turbine energy storage device comprises the following steps:

[0015] S1: Preliminary positioning, first put the battery along the telescopic plate into the protective box, then the bottom of the battery is squeezed with the telescopic plate, the telescopic plate is squeezed and drives the rotating rod to rotate along the rotating rod, the rotating rod rotates and drives the telescopic rod to rotate, the rotation of the telescopic rod contracts and squeezes the stretching spring, the telescopic rod drives the sliding blocks at both ends of the rotating shaft to slide along the limiting groove, when the bottom of the battery contacts the bottom plate, the side wall of the battery will be squeezed with the fixed sponge sleeve on the rotating shaft, so that the fixed sponge sleeve on the rotating shaft can produce preliminary positioning for both sides of the battery;

[0016] S2: Preliminary fixation. By setting a fixing mechanism, when the bottom of the battery contacts the placement bottom plate, under the action of the gravity of several batteries, the placement bottom plate presses the buffer spring downward, and the placement bottom plate moves downward to drive the rack to move downward. The rack moves downward to drive the rotating shaft on the gear to rotate. The rotation of the rotating shaft drives several push blocks 1 on the rotating shaft to move toward the side close to the clamping plate. The movement of push block 1 drives the clamping bottom plate to move toward the side close to the clamping plate. At this time, push block 1 pushes the clamping plate on push block 2 at one end of the compression spring to move toward the side wall of the battery.

[0017] S3: Stable clamping. By setting up an auxiliary mechanism, when several batteries are installed, the hydraulic rod is started, and the hydraulic rod pushes the protective cover to slide toward the central axis of the protective box. At this time, the protective cover drives the sliding block 2 at one end of the telescopic rod 2 to slide downward along the limiting groove 2. The sliding block 2 slides downward and drives the two clamping plates corresponding to the linkage rod 2 to move closer to each other. At this time, the fixed roller on the clamping plate is further squeezed with the side wall of the battery. The fixed roller is squeezed and drives the sliding ring at one end of the linkage rod to slide along the fixed column. When the sliding ring slides to both ends of the fixed column, the side wall of the clamping plate and the fixed roller are squeezed with the side wall of the battery at the same time.

[0018] The present invention has the following beneficial effects:

[0019] (1) In the present invention, when the protective device is used, the battery is first placed inside the protective box along the telescopic plate. At this time, the bottom of the battery is squeezed with the telescopic plate. The telescopic plate is squeezed and drives the rotating rod to rotate along the rotating rod. The rotation of the rotating rod drives the telescopic rod to rotate. The rotation of the telescopic rod contracts and squeezes the tension spring. The telescopic rod drives the sliding blocks at both ends of the rotating shaft to slide along the limiting groove. When the bottom of the battery contacts the placement bottom plate, the side walls of the battery will be squeezed with the fixed sponge sleeve on the rotating shaft. This arrangement is conducive to the fixed sponge sleeve on the rotating shaft to produce preliminary positioning of the two sides of the battery, and at the same time ensure that the two ends of the multiple batteries in the protective box are on the same straight line, which is conducive to the neat placement of the multiple batteries in the protective box, and is convenient for the later electrical connection of the multiple batteries in the protective box; this arrangement is also conducive to ensuring that the multiple batteries in the protective box will not move relative to each other during use of the device, thereby ensuring that the electrical connection of the multiple batteries remains stable.

[0020] (2) The present invention, by setting a fixing mechanism, when the bottom of the battery contacts the placement base plate, under the action of the gravity of a plurality of batteries, the placement base plate presses the buffer spring downward, the placement base plate moves downward to drive the rack to move downward, the rack moves downward to drive the rotating shaft on the gear to rotate, the rotating shaft rotates to drive a plurality of push blocks on the rotating shaft to move toward the side close to the clamping plate, the movement of push block 1 drives the clamping base plate to move toward the side close to the clamping plate, at this time, push block 1 pushes the clamping plate on push block 2 at one end of the compression spring to move toward the side wall of the battery, at this time, the fixed roller on the clamping plate is squeezed with the side wall of the battery, such a setting is conducive to initially fixing the battery on the placement base plate, and preventing the battery from shaking in the device during transportation and colliding with each other, thereby causing damage to the battery.

[0021] (3) The present invention sets an auxiliary mechanism. When several batteries are installed, the hydraulic rod is started, and the hydraulic rod pushes the protective cover to slide toward the central axis of the protective box. At this time, the protective cover drives the sliding block 2 at one end of the telescopic rod 2 to slide downward along the limit groove 2. The sliding block 2 slides downward and drives the two clamping plates corresponding to the linkage rod 2 to move closer to each other. At this time, the fixed roller on the clamping plate is further squeezed with the side wall of the battery. The fixed roller is squeezed and drives the sliding ring at one end of the linkage rod 1 to slide along the fixed column. When the sliding ring slides to the two ends of the fixed column, the side wall of the clamping plate and the fixed roller are squeezed with the side wall of the battery at the same time. This arrangement is conducive to increasing the squeezing area of ​​the battery side wall and further protecting the battery inside the box.

[0022] (4) In the present invention, when it is necessary to take out the battery inside the protective box, the hydraulic rod first drives the protective cover to slide toward the two ends of the protective box. At this time, the telescopic rod 2 drives the sliding block 2 to move upward, and the sliding block 2 drives the clamping plate at one end of the linkage rod 2 to move toward the end away from the battery side wall. The clamping plate is separated from the battery side wall and only the fixed roller is pressed against the battery side wall. This arrangement is conducive to reducing the resistance to the battery and facilitates personnel to smoothly take out the battery.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
