The application provides a low dam water intake automatic sand discharge system and a construction method. The low dam water intake automatic sand discharge system comprises a water retaining weir close to an upstream and a low dam close to a downstream. Three retaining walls are vertically arranged close to one side of the water retaining weir. Water inlet chambers and sand discharge chambers are formed between two adjacent retaining walls. The water inlet chambers and the sand discharge chambers are both water inlets close to one side of the water retaining weir. The side wall of the water inlet chamber is provided with a water intake. The water inlet of the water inlet chamber is provided with an inclined plate sedimentation assembly. The bottom of the sand discharge chamber is provided with a sand flushing pipe. One end of the sand flushing pipe extends through the water retaining weir to the side of the water retaining weir close to the upstream. The sand flushing pipe is connected with a sand flushing branch pipe. The water outlet of the sand flushing branch pipe extends into the sand discharge chamber to impact the sand and stones in the sand discharge chamber so that the sand and stones in the sand discharge chamber flow into the downstream along with the water flow. The application realizes automatic sand flushing by water power without external energy. The water intake of the water inlet chamber can continuously operate to avoid shutdown caused by manual cleaning.

This utility model discloses a cyclone separator for a biomass circulating fluidized bed boiler, comprising a flue gas inlet section, a gas-solid two-phase separation section connected to the flue gas inlet section, a flue gas outlet section connected to the top and bottom of the gas-solid two-phase separation section respectively, and a solid return section. The solid return section includes multiple coaxially connected and fixedly connected solid return straight sections and multiple solid return conical sections, which are arranged at intervals in the vertical direction. Flue gas flows in from the flue gas inlet section, rotates along the inner wall of the gas-solid two-phase separation section, and achieves gas-solid two-phase separation through centrifugal force. The gas phase flows out through the flue gas outlet section, and the solid phase is returned from top to bottom through the solid return section. Through segmented and optimized solid return path and gas-solid separation flow field, the intermittent blockage problem caused by alkali metal adhesion in traditional cyclone separators is solved, avoiding forced boiler load reduction or shutdown. It is especially suitable for biomass combustion scenarios with complex fuel types and variable ash composition.

The invention provides an electric auxiliary bicycle and an automatic power-off method thereof. The automatic power-off method is suitable for an electric-assisted bicycle including a battery module and includes the following steps. A charge / discharge state of the battery module is detected using a current sensing assembly of the battery module. And enabling or disabling an automatic power-off mechanism according to the charge-discharge state of the battery module. When the automatic power-off mechanism is enabled, whether to control the electric-assisted bicycle to enter a power-off state is determined according to the charge-discharge state of the battery module. Therefore, the electric auxiliary bicycle connected with the charger can be prevented from being turned on and turned off repeatedly due to idling.

The invention provides a cluster operation storage resource allocation method and device, equipment, a medium and a product, and is applied to the technical field of financial science and technology. The method comprises the following steps: performing data backup between servers based on a data intercommunication channel to obtain a database table related to operation data of each server; in response to the fact that the detection result represents that the server has a running fault, marking the server with the running fault as an isolation server, and migrating a program running by the isolation server to a backup server to run on the basis of the database table; in response to the detection result representing that all the servers in the server cluster operate normally, performing sub-table management on the database table to obtain a data sub-table corresponding to each server, and performing real-time data volume analysis on the data sub-table to obtain a data analysis result; and in response to the fact that the data analysis result represents that database storage of the server is overloaded, marking the server as an overload server, and storing overload data related to the overload server in a backup database.

This application discloses a method for lifting a multi-spoke, multi-car, traction-free elevator in a single elevator shaft, belonging to the field of engineering technology, specifically relating to a method for lifting a multi-spoke, multi-car, traction-free elevator in a single elevator shaft. This application employs dividing an elevator shaft into three spokes: an ascending spoke, a descending spoke, and a stopping spoke. When the car on the ascending or descending spoke reaches the stopping floor, it performs a 120-degree turn. o The elevator shaft rotates horizontally to the stopping bay for passenger and freight transport. Multiple cars can be installed in each bay. Each car within the three bays operates independently along its respective guide rail. If a car malfunctions, it can be lifted to the top floor or a specific floor for repair, while other cars continue to operate normally. Similarly, if a problem occurs in one bay's passageway, the other bays can continue operating normally. Each car has an independent power drive system, using a three-axis drive and three-point braking system for control. This application includes the elevator shaft walls, elevator shaft doorway, upward bay car, downward bay car, stopping bay car, intermediate guide rail, side rail, transverse rotating rail, drive gear, and drive battery.
