Abstract: Disclosed are a flow battery degassing device, a degassing method, a system, and a storage medium. The flow battery includes a liquid tank. The flow battery degassing device includes a degassing tank, a degassing pump, a liquid outlet pipe, and a liquid inlet pipe. The liquid outlet pipe is configured to enable an electrolyte in the liquid tank to flow into the degassing tank. The liquid inlet pipe is configured to enable the electrolyte in the degassing tank to flow into the liquid tank. The degassing pump is provided on the liquid inlet pipe and configured to form a vacuum environment in the degassing tank.

Abstract: Provided are a flow battery cleaning apparatus, method, and system. A flow battery includes: a positive electrode liquid tank, a negative electrode liquid tank, and a stack unit, the positive electrode liquid tank and the stack unit forming a positive electrode circulation loop, and the negative electrode liquid tank and the stack unit forming a negative electrode circulation loop. The flow battery cleaning apparatus includes a detection apparatus, a first foreign matter removal apparatus, and a second foreign matter removal apparatus, and the detection apparatus includes a first detection apparatus. The first detection apparatus is configured to detect whether foreign matter is present in the stack unit, the first foreign matter removal apparatus is configured to adjust the pressure of the positive electrode circulation loop, and the second foreign matter removal apparatus is configured to adjust the pressure of the negative electrode circulation loop.

Abstract: Embodiments of the present disclosure disclose an insulating protective mechanism, a conveying apparatus, and a flow battery energy storage system, which relate to, but are not limited to, insulating protection technology. The insulating protective mechanism comprises a frame, an insulating protective cover, a transmission assembly, a sensing assembly, and a control unit. The insulating protective cover is arranged on the frame, and can enclose with the frame an installation space for installing a conveying mechanism. The control unit controls the transmission assembly to facilitate driving the insulating protective cover to open or close the installation space, so as to facilitate maintenance and replacement of the conveying mechanism in the installation space, and reset the insulating protective cover after the maintenance and replacement of the conveying mechanism.

Abstract: Disclosed in the present utility model is a device for testing gas tightness of a bipolar plate. The device includes a fixing assembly and a liquid placing plate. The fixing assembly includes a base plate and a cover plate. The base plate and the cover plate are arranged opposite to each other, and a test space capable of accommodating a bipolar plate is formed between the base plate and the cover plate. The base plate or the cover plate is provided with a gas inlet for gas to enter the test space. The liquid placing plate is arranged in the test space and arranged to be stacked on the plate surface of the bipolar plate facing away from the gas inlet. The liquid placing plate is provided with a plurality of liquid placing recesses capable of containing liquid. The liquid placing recesses pass through opposite plate surfaces of the liquid placing plate.
