Description

Technical Field

[0001] This utility model relates to a cast-in-place high-speed magnetic levitation flywheel equipment installation well, and particularly to a concrete pouring formwork positioning mechanism for a high-speed magnetic levitation flywheel equipment installation well. Background Technology

[0002] The 30MW / 6MWh energy storage project consists of twelve flywheel energy storage frequency regulation units (2.5MW / 0.5MWh). Each flywheel energy storage frequency regulation unit includes ten high-speed magnetic levitation flywheels (250kW / 50kWh), a flywheel auxiliary system, a flywheel drive and control system, and a prefabricated boost converter integrated unit. Every six flywheel energy storage frequency regulation units are connected to the 35kV power distribution device of the energy storage power station via cables, with two aggregation units. After aggregation, the power is supplied through a 40MVA 110kV / 35kV power distribution line. After the transformer steps up the voltage, the signal is sent to the substation, which is equipped with a 110kV step-up substation, an electrical control building, a cooling tower, and other facilities. In this system, the high-speed magnetic levitation flywheel is installed in a flywheel well, which is constructed using cast-in-place concrete. The foundation bottom elevation of the flywheel well is -5.3 meters, the excavation depth of the pit is 4.1 meters, and the bearing layer of the flywheel well foundation is the third layer of silty clay. This layer has a bearing capacity characteristic value of 180 kPa and is not collapsible, making it suitable as a bearing layer. After the flywheel well is excavated, in... First, the reinforcing steel frame of the well wall is tied on the foundation pad, and then the steel formwork on the outside of the well wall is erected. Since the flywheel well contains the vacuum pump box and the high-speed magnetic levitation flywheel equipment installation foundation, a sealed steel vacuum pump box needs to be fixed and installed at the bottom of the well, and a concrete reinforcing steel frame for the high-speed magnetic levitation flywheel equipment base needs to be erected. Then, Ω-shaped special-shaped steel formwork is spliced ​​on the outside of the reinforcing steel frame, and finally, concrete is poured in one go, thus forming the flywheel well wall and the Ω-shaped concrete base of the high-speed levitation flywheel equipment. The vacuum pump box is then embedded in the poured concrete foundation. In the above process, since the formwork of the high-speed magnetic levitation flywheel foundation is suspended in the space above the bottom of the well, how to fix the formwork system becomes a problem in the concrete pouring construction. In addition, the steel vacuum pump box set at the bottom of the well is prone to floating during concrete pouring, which is the second problem that needs to be solved. Furthermore, since the high-speed magnetic levitation flywheel equipment is installed on the base by pre-embedded bolts, how to position and connect the pre-embedded bolts of the high-speed magnetic levitation flywheel equipment is the third problem that needs to be solved. Summary of the Invention

[0003] This utility model provides a concrete pouring template positioning mechanism for the installation well of a high-speed magnetic levitation flywheel device, which solves the technical problems of how to fix the concrete pouring template system of the flywheel device and how to overcome the floating of the steel vacuum pump box at the bottom of the well during concrete pouring.

A barrel-shaped embedded steel vacuum pump box is installed at the left end of the cushion layer inside the steel reinforcement skeleton. A steel reinforcement skeleton inside the concrete base for installing the flywheel equipment is tied to the cushion layer to the right of the embedded steel vacuum pump box. An Ω-shaped irregular steel template is installed at the top of the steel reinforcement skeleton inside the concrete base. An X-shaped horizontal support frame is connected to the top of the Ω-shaped irregular steel template. The four outer ends of the X-shaped horizontal support frame are all abutted against the inner vertical surface of the outer formwork for the concrete pouring of the well body sidewall. A top H-shaped steel beam is installed at the top of the outer formwork for the concrete pouring of the well body sidewall, and a vertical top rod is installed between the top H-shaped steel beam and the bottom plate inside the embedded steel vacuum pump box.

[0005] A positioning arc plate with pre-embedded bolts is set at the top of the Ω-shaped irregular steel template. The positioning arc plate with pre-embedded bolts is fixedly connected to the X-shaped horizontal support frame.

[0006] An arc-shaped block is installed at the outer end of the X-shaped horizontal support frame. The X-shaped horizontal support frame is supported on the inner side of the concrete pouring formwork of the well body sidewall through the arc-shaped block. An upper support block is installed at the top of the vertical support rod, and a lower support block is installed at the bottom of the vertical support rod. The vertical support rod is supported on the top H-shaped steel beam through the upper support block, and the vertical support rod is supported on the bottom plate of the pre-embedded steel vacuum pump box through the lower support block.

[0007] Inside the Ω-shaped special-shaped steel template, below the Ω-shaped special-shaped steel template, and outside the pre-embedded steel vacuum pump box, the lower part of the flywheel installation well concrete is poured in one go, pre-embedded the pre-embedded steel vacuum pump box, and form a concrete base with an Ω-shaped concrete step for installing the flywheel equipment.

[0008] This utility model uses an X-shaped horizontal strut frame to suspend and fix the suspended Ω-shaped irregular steel template, and uses a vertical support rod to overcome the problem of the pre-embedded steel vacuum pump box floating. It realizes the one-time casting of the pre-embedded steel vacuum pump box and the flywheel equipment foundation in the flywheel installation well.
