The utility model discloses a blood preservation device, which relates to the technical field of medical equipment and comprises a storage box, an inner cavity is arranged at the bottom end inside the storage box, a cooling fin is fixedly connected inside the inner cavity, a plurality of groups of placing holes are arranged at the top end of the storage box, caps are arranged at the tops of the placing holes, and the cooling fin is fixedly connected with the inner cavity. A set of communicating holes are formed in the bottom end of each containing hole in the circumferential direction, a control panel is fixedly connected to the front side of the storage box, springs are fixedly connected to the bottom ends of the containing holes, pressure sensors are fixedly connected to the top ends of the springs, and display lamps are fixedly connected to the top ends of caps. According to the technical scheme, whether the sample tubes can be placed in the placing holes or not can be judged by arranging the sample tubes in the placing holes, and the placing holes are separated, so that the temperature in other placing holes cannot be influenced when the sample tubes are taken or stored, the conditions of temperature loss and blood degeneration are avoided, and the accuracy of a detection result is ensured.

The invention provides a coffee machine milk conveying device, and relates to the technical field of beverage machine milk conveying devices.The coffee machine milk conveying device comprises a mounting base, a mounting groove is formed in the upper surface of the mounting base, the inner wall surface of the mounting groove is rotationally connected with a lead screw body through a bearing, and the outer surface of the lead screw body is in threaded connection with a lead screw sleeve; the upper surface of the lead screw sleeve is fixedly connected with a push plate. The screw rod sleeve drives the push plate to get close to the backup plate and extrude the milk box under the action of the threads, the volume in the milk box is reduced, the pressure is increased, milk is added into the coffee machine through the insertion pipe and the milk conveying pipe, and no air enters the milk box, a milk pipeline and a milk pump in the milk conveying process; the milk can be kept at normal temperature without refrigeration, the fusion of the milk and coffee and the temperature of the coffee are not influenced, the good taste is ensured, refrigeration equipment is omitted, the product cost and the operation and maintenance cost are reduced, and the milk maker is green and energy-saving and does not occupy the counter area.

The present application relates to the technical field of flexible direct current transmission, and particularly relates to a discharge method of a flexible direct current converter valve operation test system, when a stop command is issued, all power modules of the flexible direct current converter valve continue to operate discharge according to the stop command in a specific current modulation mode, until all the power modules are at the lowest set voltage, and then static discharge is performed until the voltage of all the power modules drops to a safe voltage, that is, the discharge is completed; wherein the specific current is a current less than 50% of the rated current. The stop and lock discharge strategy adopted in the present application does not require an additional discharge device, improves the discharge rate of the flexible direct current converter valve test, reduces the flexible direct current converter valve discharge waiting time, improves the production and test efficiency of the flexible direct current converter valve equipment, improves the design and type test verification speed, and improves the production routine test capacity.
