The invention provides a solid-liquid separation device for a centrifugal machine. The solid-liquid separation device comprises a shell, cover plates, a filter disc and a centrifugal machine body, wherein the cover plates are buckled at the upper part of the shell, the filter disc is located in the shell and is connected with the bottoms of the cover plates, and the centrifugal machine body is located at the lower end of the shell; a liquid outlet formed in the bottom of the filter disc and a liquid inlet formed in the top of the centrifugal machine body are connected through a pipeline; the centrifugal machine body is further connected with a liquid outlet pipe, and a flow guide groove is formed in the inner wall of the liquid outlet pipe. According to the solid-liquid separation device for the centrifugal machine, by forming the flow guide groove in the inner wall of the liquid outlet pipe, a phenomenon that a liquid draining passage is blocked by separated crystals of crystallized materials is avoided; large-particle impurities such as colloids are filtered by virtue of the filter disc before a mother solution is subjected to solid-liquid separation, so that the purity of separated solids is improved.

The invention discloses a building anti-seismic structure simulation device. The fixed support includes a plurality of fixed rods, and the plurality of fixed rods can be raised and lowered on the table surface of the external vibration table, and the upper end of the fixed rod is detachably connected with the external experience table. A disassembly and assembly device for a support and a table top, the disassembly and assembly device comprises a disassembly and assembly base arranged on the table surface and a rotatable rotating sleeve sleeved on the disassembly and assembly base. In the building earthquake-resistant structure simulation device of the present invention, by setting the switching device to switch the motor and link it with the disassembly and assembly device, it can effectively realize that the seismic isolation support can be completely detached when it is fixedly connected, so that it can be better conducted an experience experiment.

The invention provides a millisecond-level fast reconfiguration method and system for a power supply network after a power grid fault. Fast network reconfiguration The main station collects grid status information from substations or substations of power plants, and compares it with the built-in control strategy table that may fail; The corresponding sub-station sends a closing pre-start signal; when the fault is cleared, the sub-station identifies the clearing time according to the local information, and sends a detection synchronous closing signal to the corresponding local recovery network circuit breaker; at the same time, the main station independently monitors To clear the fault, send a backup inspection synchronous closing signal to the corresponding recovery network circuit breaker, based on the above mechanism, the disconnected power grid will be re-connected to the grid within 150ms after decommissioning. After the power grid is restored to interconnection, the circuit breakers forming the electromagnetic ring network are opened.

The invention discloses a charging base with a conductive needle, which includes a body, and a conductive needle telescopically positioned on the body through an elastic mechanism. The conductive needle forms a charging electrode, and the part protruding from the body is at least as high as The distance between the main unit and the main body when charging, after pressing, the conductive needle is supported by the elastic mechanism, and keeps in pressure contact with the charging electrode on the main unit. In this application, the conductive needle is used as the charging electrode to contact the charging electrode of the host for charging. Since the conductive needle is telescopically positioned on the body through the elastic mechanism, the elastic mechanism shrinks under pressure during charging, keeping the pressure contact between the conductive needle and the charging electrode on the host. , to ensure effective contact between the charging electrodes of the host and the charging stand during charging, and improve stability.

The invention discloses a rapid blade installation structure. The rapid blade installation structure comprises a blade fork, a blade and a clamping plate; one side of the blade fork is provided with at least three protruding positioning clamping platforms; at least three through holes which are corresponding to the positioning clamping platforms are correspondingly arranged on the blade; the heads of the positioning clamping platforms are provided with a surrounding annular grooves; the clamping plate is provided with clamping holes and a plurality of lateral clamping openings; the number of the clamping holes is identical to that of the positioning clamping platforms; heads of the positioning clamping platforms respectively penetrate and extend out of the corresponding through holes; the clamping plate and one annular groove of one positioning clamping platform are clamped through the clamping hole; the lateral clamping openings are clamped into the annular grooves of the other positioning clamping platforms from the lateral side in a rotary mode. According to the rapid blade installation structure, the blade and the blade fork are fixed through the clamping plate by locking after being clamped, the assembling is simple and rapid, real-time detachment and adjustment is convenient, the structure is firm, safe and reliable, a mode of auxiliary positioning through a positioning protruding point is adopted, the safety is further reinforced, and the rapid blade installation structure is particularly suitable for rotary blades.
