The invention relates to the technical field of electric power calandria construction, and discloses a soft soil foundation electric power calandria connecting and fixing structure and a construction method.The soft soil foundation electric power calandria connecting and fixing structure comprises a bottom plate, supporting mechanisms are arranged on the two sides of the upper portion of the bottom plate correspondingly, mounting plates are fixedly connected to the two sides of the exterior of the bottom plate correspondingly, and reinforcing mechanisms are arranged on the two sides of the interiors of the two mounting plates correspondingly; the supporting mechanism comprises first arc-shaped blocks, the first arc-shaped blocks are arranged on the two sides of the upper portion of the bottom plate, and the rear sides of the exteriors of the first arc-shaped blocks are rotationally connected with connecting plates. The bottom plate is placed on a soft soil foundation, supporting is provided, foundation pressure is dispersed, the first arc-shaped block is adjusted according to the length of the electric power calandria, the H-shaped insertion block is inserted into the H-shaped insertion groove of the bottom plate, stable connection is formed, shearing stress of reinforcing steel bars is reduced, then the second arc-shaped block is opened, the electric power calandria is clamped by the second arc-shaped block and the first arc-shaped block, and gravity and shearing force are evenly dispersed. Shear force concentration is avoided, steel bar deformation is reduced, and the service life is prolonged.

The utility model discloses a battery box fire extinguishing device and vehicle battery system and fork truck, including fire extinguishing host computer, first control valve and second control valve, and fire extinguishing host computer is equipped with fire extinguishing agent output port, first control valve is equipped with first import, always with first import intercommunication's first export, the second export of switchable on-off, second control valve is equipped with second import, the third export of switchable on-off, first control valve is equipped as one time, and fire extinguishing agent output port intercommunication first control valve's first import, and first control valve's first export intercommunication second control valve's first import, when first control valve is equipped as multiple, and multiple first control valve series connection forms multistage flow path, wherein, first import intercommunication fire extinguishing agent output port of first stage, and first export intercommunication second import of last stage, and through first export of former stage intercommunication first import of latter stage between adjacent stage. When the number of battery box changes, only need to adjust the number of first control valve accordingly, namely can complete system expansion or simplification quickly.

The utility model belongs to the technical field of flow batteries, and particularly relates to a gas circulation system of a flow battery. The flow battery gas circulation system comprises a positive electrode liquid storage tank, a negative electrode liquid storage tank, a gas inlet pipeline, a gas exhaust pipeline, a gas pressure balance pipeline and a gas transfer device, the upstream end of the air inlet pipeline is positioned above the liquid level of the positive electrode liquid storage tank; the downstream end of the gas inlet pipeline is communicated with the inlet of the gas transfer device; the outlet of the gas transfer device is communicated with the upstream end of the exhaust pipeline; the downstream end of the exhaust pipeline is located below the liquid level of the negative electrode liquid storage tank. And two ends of the air pressure balance pipeline are respectively communicated to positions above the liquid levels of the positive electrode liquid storage tank and the negative electrode liquid storage tank. The gas transfer and reactive gas absorption process is realized, volatile gas and toxic waste gas can be quickly and effectively absorbed, the pressure balance of the positive and negative electrode liquid storage tanks is maintained, the change of active components of the electrolyte during operation is avoided, and the safety and high efficiency of long-time operation of the flow battery are maintained.

The invention relates to a 3D printing material based on a decoration waste recycled material, a preparation method of the 3D printing material and application of the 3D printing material to a 3D printing sound barrier. The 3D printing material comprises the following components in parts by weight: 50 parts of decoration waste lightweight aggregate; 90 to 120 parts of cement; 30 to 45 parts of water; 1-2 parts of a thickening agent; 5 to 7 parts of nano clay; 0.5 to 1.0 part of a retarder; 0.5 to 1.0 part of a water reducing agent; the decoration garbage lightweight aggregate is selected from at least one of waste aerated blocks, waste wood, waste rubber or waste plastic. The 3D printing material is used for constructing a sound barrier with more excellent sound absorption and insulation functions through a 3D printing technology. Compared with the prior art, high-quality utilization of the construction waste is achieved, meanwhile, the technical advantages of 3D printing are fully utilized, and the sound barrier which is provided with sound absorption cavities and stripe structures and can be continuously printed on site or prefabricated in batches in a factory is designed and built.
