Description

Technical Field

[0001] This invention belongs to the field of infrastructure technology, and specifically relates to an energy storage container yard and its construction method. Background Technology

[0002] With China's goals of achieving carbon peaking and carbon neutrality, the country is accelerating the construction of an energy supply system based on clean and low-carbon energy. The configuration of battery energy storage in large-scale new energy base projects such as wind power, photovoltaics, and solar thermal power has become an inevitable trend, and the application of large-scale energy storage containers in engineering projects is increasing.

[0003] However, for large-scale energy storage projects, the sheer number of battery containers necessitates careful design, layout, and construction, which significantly impacts project costs. Current technologies typically involve independently arranging containers at intervals in large-scale energy storage projects, with lifting and installation processes relying on mobile cranes and other lifting equipment. This approach fails to consider lifting and installation equipment during the design phase, neglecting the need for travel and operating space for these devices. Consequently, site utilization is inefficient, and the complex civil engineering design hinders land conservation, on-site constructability, and the application of more efficient construction and installation equipment. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this invention is to provide an energy storage container yard and construction method. By using a gantry crane and a parallel track-changing device, the hoisting of multiple rows of parallel energy storage containers can be completed, which helps to facilitate construction and installation, save construction time, and thus reduce construction costs.

[0005] The technical solution of the present invention is as follows: an energy storage container yard, comprising multiple energy storage container areas arranged in rows or columns, with a permanent road surface between adjacent energy storage container areas, and a gantry crane parallel track in the middle of the transverse permanent road surface, with a gantry crane mounted on the gantry crane parallel track, a limiting block at one end of the gantry crane parallel track, and a rotatable gantry crane impact frame at the other end, with a track-changing device on the outside of the rotatable gantry crane impact frame, the track-changing device comprising two parallel vertical guide rails, with two vertical guide trolleys between the vertical guide rails, one end of the vertical guide trolley contacting the gantry crane parallel track on one side of the rotatable gantry crane impact frame, and the other end having an extension track impact frame on its outside.

[0006] The energy storage container area is equipped with multiple energy storage container units, each including an energy storage container. A pile top platform frame is provided below the energy storage container, and multiple energy storage container piles are connected below the pile top platform frame. The energy storage container piles are fixedly buried underground.

[0007] The energy storage container includes a PCS lift-up transformer container and battery containers located on both sides of the PCS lift-up transformer container. The battery containers are electrically connected to the PCS lift-up transformer container, and the energy storage container weighs 20t~60t.

[0008] The energy storage container pile body is a precast pipe pile or a cast-in-place concrete pile.

[0009] The vertical guide rails are equipped with vertical track impact frames at both ends, and vertical traction hand chain hoists are installed on the inner sides of the two parallel vertical guide rails. The bottom of the vertical traction hand chain hoist is equipped with a traction anchor. The vertical traction hand chain hoist is fixed by the traction anchor to achieve traction of the vertical guide trolley.

[0010] A connecting rod is provided between the two vertical guide trolleys.

[0011] The rotatable gantry crane frame includes a steel support, with bases connected to both sides of the bottom of the steel support. A rotating shaft is provided between the steel support and the bases. The bases are provided with multiple anchor bolts, which are fixedly connected to the reinforced concrete foundation at the bottom of the gantry crane's parallel track. A track hole is formed between the steel support and the bases, and the gantry crane's parallel track passes through the track hole.

[0012] The vertical guide trolley includes a steel structure support, with multiple sets of wheels below the steel structure support. The wheels are rotatably connected to the vertical guide rail. Anchor bolts are provided on the outer side of the steel structure support, and anchor nuts are connected to the top of the anchor bolts. The anchor nuts fix the steel structure support to the anchor bolts. Pull lugs are provided on the inner side of the steel structure support, and the pull lugs are connected to the vertical traction hand chain hoist.

[0013] A construction method for an energy storage container yard, using an energy storage container yard as described above, includes the following steps:

[0014] S1: Site leveling, followed by the division of the energy storage container area and permanent road construction;

[0015] S2: Construct energy storage container piles within the energy storage container area and erect a pile top platform frame;

[0016] S3: Construct parallel rails for the gantry crane on a permanent road surface and install the gantry crane; install a rail-changing device on the outside of the parallel rails for the gantry crane.

[0017] S4: Use a gantry crane to lift energy storage containers sequentially within the energy storage container area. First, lift the energy storage containers between the parallel tracks of the gantry crane. After completion, rotate the rotatable gantry crane frame to move the gantry crane to the track changing device to change tracks to the next set of parallel tracks. Then lift all the energy storage containers in the next set of parallel tracks. Repeat the above steps until all energy storage containers in the energy storage container area are installed. After all energy storage containers in the energy storage container area are installed, remove the gantry crane or use it as a permanent maintenance device to complete the overall construction.

[0018] The technical advantages of this invention are as follows: 1. This invention uses a gantry crane and a parallel track-changing device to complete the hoisting of battery container yard equipment in multiple parallel rows of energy storage projects. It achieves track-changing between multiple sets of parallel tracks without disassembling the gantry crane, which facilitates construction and installation, saves construction time, and reduces construction costs. 2. This invention uses vertical guide rails and guide trolleys to move the mobile crane vertically, allowing for the use of only one mobile hoist with a normal span. By changing the position between parallel tracks, it achieves large-scale lifting and hoisting. 3. This invention uses a gantry crane and track-changing device, avoiding the drawbacks of high hoisting costs associated with existing truck cranes and other lifting machinery when the number of loads is too large or the construction period is long. It reduces the requirements for on-site transportation routes for lifting equipment, which helps reduce the spacing between engineering entities and the land area required for the energy storage area. The gantry crane and track-changing device can also be used as permanent installations, which is beneficial for the subsequent operation and maintenance of the project.
