[0002] Given that energy storage container products are widely used on the power generation side, transmission side and user side, with the deepening implementation of the national "dual carbon" strategy, energy storage container products will become an indispensable part of the source, grid, load and storage of the new power system. Since there are many electronic components inside the energy storage container and it is filled with lithium batteries, external impact can easily cause failures, which limits the use of energy storage containers in places such as border mountainous areas where it is difficult to build roads for transportation. These areas generally use photovoltaic power generation. If they are equipped with energy storage containers, the power environment in the area will be greatly improved. Therefore, it is very necessary to use helicopter lifting. The vibration, shock or impact during the helicopter lifting process is also a difficulty that must be faced. At present, there is a shortage of relevant solution technologies. Our company specializes in the research and development and production of energy storage products. We have specially organized research and development forces to carry out technical research on this situation and have produced a variety of technical solutions to cope with this difficulty.

The electromagnet is arranged at the end of the cable reel away from the traction cable and is electrically connected to the controller in the cable reel. The controller can receive remote control instructions from a ground remote control terminal to turn on and off the power of the electromagnet.

[0007] Furthermore, the controller and the electromagnet are electrically connected to the energy storage container via a breakable power supply structure, the energy storage container supplies power to the controller and the electromagnet, and when the controller controls the electromagnet to cut off power so that the cable reel cannot be magnetically adsorbed on the energy storage container, the breakable power supply structure is broken into two parts, and the two parts are respectively on the energy storage container and the cable reel.

[0011] Furthermore, the height of the lower end of the one-way movable pressure plate pressed against the traction cable and the height of the part of the one-way fixed bracket pressed against the traction cable are both greater than the height of the highest part of the traction cable and the traction wheel.

DETAILED DESCRIPTION

[0023] Embodiment 1:

[0024] like Figure 1-Figure 5 As shown, the present invention provides a ground traction device for an energy storage container, comprising a corner locking block 24, a vertical cable 1, a cable connecting block 2, a branch cable 3, a lifting frame 4, a traction cable 5, a cable reel 6, a remote control electromagnetic adsorption structure, a ground traction base, a traction wheel 16 and a one-way locking structure. The lifting frame 4 is a square frame structure and is provided with corner locking blocks 24 for locking with the lifting corners of the energy storage container 9 at four corners. The portion of the corner locking block 24 located above the lifting frame 4 is provided with a handle 25 that can be manually rotated and locked. Corner connecting blocks 22 are respectively provided on the outer sides of the four corners of the lifting frame 4. A cable rotating column 21 is hinged on the corner connecting block 22. The upper end of the cable rotating column 21 extending out of the corner connecting block 22 is embedded with and locked with a branch cable 3. The upper ends of the four branch cables 3 are gathered at the center above the energy storage container 9 and are held by the cable The connecting block 2 is connected with the vertically extending vertical cable 1, and a traction connecting block 23 is provided on the outer side of the corner connecting block 22, and a traction cable 5 is embedded and locked on the traction connecting block 23, and a cable reel 6 is provided on the part of the traction cable 5 away from the suspension frame 4, and an end of the cable reel 6 away from the traction cable 5 is provided with a remote-controlled electromagnetic adsorption structure for winding up the traction cable 5 and capable of magnetically adsorbing the cable reel 6 on the outer wall of the energy storage container 9, and a ground traction base is provided on the end of the traction cable 5 away from the suspension frame 4, and a reel clamp 18 is provided on the part of the ground traction base close to the suspension frame 4, and a traction wheel 16 is hinged on the reel clamp 18, and the traction cable 5 passes around the lower side of the traction wheel 16 on the ground traction base and is unidirectionally locked by a unidirectional locking structure, so that the traction cable 5 can only be dragged in the direction away from the suspension frame 4 on the ground traction base.

[0025] Usage mechanism: before the energy storage container 9 is hoisted for transportation, the traction cable 5 is wound around the corresponding cable reel 6, and the cable reel 6 is magnetically adsorbed to the lower side of the side wall of the energy storage container 9 by the remote control electromagnetic adsorption structure; when the energy storage container 9 is hoisted by the helicopter, as the energy storage container 9 gradually approaches the ground, when the height of the energy storage container 9 from the ground is within 2m, the ground personnel control the ground remote control terminal to send a power-off command to the electromagnet 19. After the electromagnet 19 is powered off, the cable reel 6 and the remote control electromagnetic adsorption structure can rely on their own weight to detach from the side wall of the energy storage container 9, and the pulling cable is released from the corresponding cable reel 6 until the traction cable is released. The end of the rope 5 away from the energy storage container 9 falls on the ground, and four ground personnel respectively introduce the ends of the four traction cables 5 into the corresponding ground traction bases. The traction cables 5 pass through the traction wheels 16 and the one-way locking structure on the ground traction bases in sequence. The four ground personnel synchronously drag their respective corresponding traction cables 5. If a ground personnel finds that the traction cable 5 corresponding to him is not taut, he notifies the other three ground personnel to pay attention to dragging faster, so that the energy storage container 9 can be better pressed against the ground bearing platform when it lands, thereby improving the installation quality of the energy storage container 9 hoisted by the helicopter.

[0026] like Figure 2 and Figure 5 As shown, the remote control electromagnetic adsorption structure includes an electromagnet 19 and a PLC controller. The electromagnet 19 is arranged at the end of the cable reel 6 away from the traction cable 5 and is electrically connected to the PLC controller in the cable reel 6. The PLC controller can receive remote control instructions from the ground remote control terminal to turn on and off the power of the electromagnet 19. The PLC controller and the electromagnet 19 are electrically connected to the energy storage container 9 through a breakable power supply structure. The energy storage container 9 supplies power to the PLC controller and the electromagnet 19. When the PLC controller controls the electromagnet 19 to cut off the power so that the cable reel 6 cannot be magnetically adsorbed on the energy storage container 9, the breakable power supply structure is disconnected into two parts and the two parts are respectively on the energy storage container 9 and the cable reel 6.

[0027] Among them, the disconnectable power supply structure includes an upper wire, a lower wire, a socket and a plug. The upper wire and the lower wire are electrically connected to the energy storage container 9 and the controller respectively, and the opposite ends are provided with a socket and a plug respectively. The socket and the plug are plugged together one above and one below, and the force of the mutual plug-in locking is less than the gravity generated by the self-weight of the cable reel 6 and the remote control electromagnetic adsorption structure, so that the cable reel 6 and the remote control electromagnetic adsorption structure can rely on their own weight to pull the plug away from the socket.

[0028] like Figure 2 and Figure 5As shown, a locking sleeve 17 is provided at the end of the cable reel 6 near the traction cable 5. The locking sleeve 17 is nested on the traction cable 5 and a locking bolt is spirally embedded on the outer side. The end of the locking bolt embedded in the locking sleeve 17 is pressed against the traction cable 5, so that the cable reel 6 and the traction cable 5 are locked together.

[0029] like Figure 2 and Figure 5 As shown, the one-way locking structure includes a one-way movable pressure plate, a one-way fixed bracket 12, a tension spring 13 and an articulated clamp 14. Two parallel articulated clamps 14 are provided on the ground traction base away from the traction wheel 16 and the suspension frame 4. The traction cable 5 passes through the two articulated clamps 14. The part between the two articulated clamps 14 and close to the suspension frame 4 is hinged with a one-way movable pressure plate. The one-way movable pressure plate extends in the direction away from the suspension frame 4 and tilts downward. A one-way fixed bracket 12 is provided below the lower end of the one-way movable pressure plate. The lower end of the one-way movable pressure plate and the corresponding parts of the one-way fixed bracket 12 are pressed against the traction cable 5 respectively. Tension springs 13 are provided on both sides of the lower end of the one-way movable pressure plate. The tension spring 13 extends downward on both sides of the one-way fixed bracket 12 and the lower end is arranged on the ground traction base, so that the end of the traction cable 5 can only be dragged in the direction away from the suspension frame 4.

[0030] In order to ensure that the one-way locking structure can better play the role of one-way locking the traction cable 5, the height of the lower end of the one-way movable pressure plate pressed against the traction cable 5 and the height of the part of the one-way fixed bracket 12 pressed against the traction cable 5 are both greater than the height of the highest part of the traction cable 5 and the traction wheel 16. In particular, when the traction cable 5 is towed, the traction cable 5 cannot be pulled upward to lift the one-way movable pressure plate in the one-way locking structure, thereby making the one-way locking effect of the one-way movable pressure plate invalid.

[0031] like Figure 2 and Figure 5 As shown, the ground traction base includes a ground bolt 7 and a bearing plate 8 , and the bearing plate 8 is vertically penetrated by the ground bolt 7 extending vertically downward from top to bottom, so that the bearing plate 8 is locked on the ground by the ground bolt 7 .

[0032] In order to facilitate picking up and threading the traction cable 5 to the lower side of the traction wheel 16 and the one-way locking structure after it falls, a cable traction head 11 is fixedly provided at the end of the traction cable 5 away from the lifting frame 4, wherein the outer diameter of the cable traction head 11 is larger than the outer diameter of the traction cable 5 and also larger than the inner diameter of the locking sleeve 17, which also prevents the cable reel 6 from slipping off the traction cable 5 due to the loose locking of the locking sleeve 17.
