This invention provides a test tube storage device, belonging to the field of test tube storage technology. It includes a storage box, with a storage cover rotatably connected to one side of the upper surface of the storage box. A storage base plate, test tube rack, fixing components, a cooling plate, and a cooling fan are inserted into the lower surface of the storage box. This invention utilizes a design where a desiccant packet is placed inside the heat dissipation base after the heat dissipation cover is opened. The desiccant packet absorbs water, reducing condensation from the cooling element flowing into the heat dissipation base and outwards. The heat dissipation element dissipates heat from the cooling element, and the cooling fan draws heat from the cooling element into the heat dissipation base and expels it outside. The cooling element cools one end, and the cooling fan draws air from the storage box into the top of the cooling element for further cooling. The cold air is then expelled from the outlet into the storage box, further cooling it. This method preserves samples stored in test tubes within the storage box, slowing down sample metabolism and degradation, effectively inhibiting microbial growth and reproduction, and extending sample preservation time.

This application relates to a foundation pit support structure, specifically within the technical field of foundation pit support. It includes a plurality of adjacent and connected Larssen sheet piles, which abut against the inner wall of the foundation pit. A support mechanism is provided within the foundation pit. The support mechanism includes a support plate abutting against the inner wall of the Larssen sheet piles, and a top plate abutting at the connection points of adjacent Larssen sheet piles. The support mechanism also includes a support seat disposed within the foundation pit, with a top support assembly on the support seat. The support plate pushes the top plate against the Larssen sheet piles via the top support assembly. This application improves the support capacity of the sheet piles and reduces the potential for damage to the sheet piles.

The utility model discloses an engine degassing device and engineering machinery, including engine, the engine is equipped with EGR, EGR is equipped with degassing port, and the degassing port is connected with one end of degassing pipe, and the other end of degassing pipe is connected with the first port of three -way valve, and the second port of three -way valve is connected with one end of first backwater pipe, and the other end of first backwater pipe is connected with radiator, and the engine is equipped with engine inlet pipe, and the radiator is connected with engine inlet pipe, and the third port of three -way valve is connected with one end of second backwater pipe, and the other end of second backwater pipe is connected with engine inlet pipe. The utility model discloses reasonable in structure design, the utility model increases a three -way valve, and three -way valve passes through the effect of shunting and three -way valve passes through the change of the second port's through -diameter or reduces the through -diameter of first backwater pipe, reduces the amount of coolant inflow radiator, reduces temperature loss.

This utility model provides a low-voltage intelligent reactive power compensation control cabinet, comprising: a cabinet body, a main partition plate fixedly connected to the upper end of the cabinet body, a secondary partition plate fixedly connected to the lower end of the cabinet body, and a mounting plate fixedly connected to the middle of the cabinet body cavity by bolts. A temperature sensor is fixedly connected to the lower surface of the mounting plate. A guide plate and an air guide tube are fixedly connected to the upper surface of the main partition plate, and air outlets are opened on both sides of the cabinet body corresponding to the positions of the air guide tubes. A flow divider box is fixedly connected to the upper surface of the secondary partition plate, and air jet plates are symmetrically connected to both sides of the flow divider box. An air pump is fixedly connected to the lower surface of the secondary partition plate. This utility model, through the cooperation of the flow deflector plate, filter plate, air pump, flow divider box, and air jet plates, can enhance the airflow speed inside the control cabinet cavity, improve the heat dissipation effect inside the control cabinet, and also assist in filtering and drying the incoming external airflow, reducing the probability of accidental damage to the electrical components inside the control cabinet.
