Recovery device for urea solution for vehicles

The utility model discloses a recovery device for adblue solution, including the bracing frame, be equipped with the processing subassembly on the bracing frame, the processing subassembly includes fixed seat, processing cylinder, motor, stirring rod and connecting plate, fixed seat is equipped on the bracing frame, processing cylinder is equipped on the fixed seat, the motor is equipped on the stirring rod, and the connecting plate is equipped on the motor. The motor is fixedly installed on the treatment barrel, the stirring rod is connected to the output end of the motor, the connecting plate is arranged on the stirring rod, a filtering assembly is arranged at the bottom of the treatment barrel and comprises a discharging pipe, a filtering box and a feeding hopper, the discharging pipe is installed at the bottom of the treatment barrel, a valve is arranged on the discharging pipe, and the filtering box is connected with the discharging pipe. And the filter box is arranged at the bottom of the discharge pipe, so that the technical problems that urea and other components in a solution cannot be uniformly mixed and the use effect of the solution and the efficiency of a catalytic reduction reaction are influenced due to the fact that an effective stirring mechanism is generally lacked in an existing recovery device mentioned in the background technology are solved.

A system and method for water replenishment and replacement through multi-gate control

ActiveCN116732949BSolve the loop problemBarrages/weirsRiver routingWater quality
This invention discloses a system and method for water replenishment and exchange through multi-gate coordinated control, comprising: a river channel; and a first control gate assembly and a second control gate assembly respectively disposed in the upstream and downstream sections of the river channel, and further comprising multiple channels disposed in the river channel and positioned between the first and second control gate assemblies. This invention utilizes natural tidal energy to replenish and exchange water in the inland river channel through multiple gates, while simultaneously and rationally coordinating the opening and closing of the upstream and downstream first and second control gate assemblies, thereby ensuring a long-term unidirectional flow state in the inland river channel, increasing water circulation, and ultimately improving the water quality of the inland river channel.

A satellite network routing update method, system, electronic device and storage medium

PendingCN122512986ASolving rule propagationSolving Consistency IssuesPathPingTelecommunications
The application discloses a satellite network routing update method and system, electronic equipment and storage medium, and mainly solves the problem that non-landing satellite configuration data is lost in the transmission process due to link failure, leading to routing sending failure or loop. The routing update method provided by the application quickly and reliably converges the routing. The method comprises the following steps: (1) refreshing topology data after receiving satellite failure, calculating the shortest path from the gateway station to the satellite based on the minimum hop strategy; determining the home gateway station of the satellite and recording the corresponding shortest path length; (2) dividing the satellites into different batches according to the shortest path length, and completing the satellite routing update in batches from near to far; (3) sending routing update instructions to a plurality of satellites in the same batch in a concurrent manner, and forwarding only through the updated node or gateway station direct path.

Top drive type tail pipe cementing head, tail pipe cementing system and cementing process

PendingCN122280500ASolve the loop problemEasy to installTop driveWell cementing
This invention discloses a top-drive type tailpipe cementing head, a tailpipe cementing system, and a cementing process. The cement head body comprises a cement head body, a rubber plug pre-installation mechanism, and a drill pipe tandem connector. The cement head body is used to connect to the top drive system at its upper end. At least one union joint is milled on the cement head body. The cement head body has an internal cavity. The rubber plug pre-installation mechanism is installed within the cavity. The rubber plug pre-installation mechanism includes a rubber plug sleeve and a drill pipe rubber plug. A fluid channel is provided on the side wall of the rubber plug sleeve. The drill pipe rubber plug is installed inside the rubber plug sleeve. The drill pipe rubber plug is used to scrape the drill pipe under the action of displacement fluid. The drill pipe tandem connector is connected to the lower end of the cement head body. The drill pipe tandem connector is used to connect the drill pipe string. This invention solves the problem of the need for multiple connection and disassembly of conventional cement heads in tailpipe cementing; solves the circulation problem of the top drive system under drill pipe rubber plug pre-installation; and solves the problem of continuity of tailpipe cementing construction throughout the entire process.
