The invention relates to an SDN switch, an operation method thereof and an SDN controller, belongs to the field of communication technology, and aims at enabling the SDN switch to continue forwarding data packets and ensuring uninterrupted services after that the SDC switch is disconnected from the SDN controller. The method applied to each of at least one SDN switch disconnected from the SDN controller comprises that the SDN switch receives a message to be processed; and according to a corresponding forwarding rule received when the SDN switch is disconnected, the SDC switch processes the message to be processed. Thus, the SDN switch can continue forwarding the data packet after being disconnected from the SDN controller, and it is ensured that the service is uninterrupted.

The invention uses multi firewalls to construct a highly efficient and stable route link. The invention also provide an apparatus thereof used for providing a virtual gateway address for each firewall; each client is pointed to different virtual gateway so as to balance the traffic on each firewall; when one firewall fails, other firewalls can take over the address of the failure firewall to keepthe network traffic in normal state.

The invention discloses an arc type overflow dam capable of automatically washing away sand and reducing siltation and a running method of the arc type overflow dam. The arc type overflow dam capable of automatically washing away sand and reducing siltation comprises a dam body, a flow releasing and sand discharging hole, gate slots, gates, a guide wall and a protection bank. The arc type overflow dam capable of automatically washing away sand and reducing siltation is characterized in that the dam body is of an arc reinforced concrete structure; the flow releasing and sand discharging hole is formed in the right side of the dam body; the gate slots are formed in the inner walls of the two sides of the flow releasing and sand discharging hole; the gates are manual steel gates and are installed on the gate slots; the guide wall is of an anti-scouring reinforced concrete structure and is arranged on the upstream right bank; and the protection bank is of an anti-scouring reinforced concrete structure and is arranged on the downstream left bank. In the water season, the steel gates are opened, bend transverse ring flow formed by the arc dam body is utilized for automatically conducting flow releasing and sand washing; and in the dry season, the steel gates are closed, the water level is elevated, and water is stored. Compared with traditional mountainous area overflow dams, the arc type overflow dam has the beneficial effects that the form is decent and attractive, little mud and little sand are deposited in front of the dam, the siltation reducing cost is low, and the comprehensive benefits of the project are more obvious.

The slug flow catcher provided by the invention is used for oil gas treatment of oil gas field surface engineering.

The invention relates to an outdoor hydroelectric generating set generating electricity through hydropower station ecological flow. The outdoor hydroelectric generating set generating electricity through the hydropower station ecological flow is characterized by comprising a water turbine, a horizontal type asynchronous generator, a water inlet valve, a diffusion pipe and a hammer type butterfly valve; the diffusion pipe is arranged at the tail end of a branched pipeline which is perpendicularly connected with a main pipeline of an ecological flow drainage pipe; the convergence end of the diffusion pipe is connected with the tail end of the branched pipeline; the diffusion end of the diffusion pipe is connected with a water inlet of the water turbine; the water turbine is connected with an asynchronous motor to drive the asynchronous motor to generate electricity; the water inlet valve is arranged on the branched pipeline which is connected with the diffusion pipe; the hammer type butterfly valve is arranged at a water outlet of the ecological flow drainage pipe; the water inlet valve is opened and the hammer type butterfly valve is closed when the water turbine drives the asynchronous generator to generate electricity, the ecological flow sequentially passes the main pipeline, the water inlet valve and the diffusion pipe to flow into the water turbine, the water turbine drives the asynchronous generator to generate electricity, and the ecological flow after work is discharged through the water turbine; when the asynchronous motor does not generate electricity, the hammer type butterfly valve is opened and the ecological flow is discharged through the hammer type butterfly valve.

The invention discloses a preparation method and equipment of a magnetic nano-composite material, and relates to the technical field of preparation of magnetic nano-materials. The preparation method and equipment of the magnetic nanocomposite material include a stirring tank, the outer wall of the upper part of the stirring tank is provided with a heating cavity, the upper end surface of the upper cover is provided with a feeding pipe, and the middle part of the upper end surface of the upper cover passes through The mounting frame is fixedly connected with a stirring motor, the output shaft end of the stirring motor is fixedly connected with a stirring shaft, the lower part of the stirring shaft is fixedly connected with a long stirring blade and a short stirring blade, and the inner cavity of the heating chamber is respectively provided with The first cooling cavity and the second cooling cavity, the inner cavity of the heating cavity is symmetrically arranged with irradiation heating devices, which solves the problems of low mixing efficiency of liquid raw materials and powder, and poor heating and cooling effects in the existing magnetic nanocomposite material preparation equipment. This leads to the problem of low production efficiency of the entire magnetic nanomaterials.

The invention discloses a dust-removing and heat-dissipating monitor, which comprises a housing, and the inner wall of the housing is symmetrically provided with a launching slot and a receiving slot, and the inner walls of the launching slot and the receiving slot are respectively fixed with a light source and a photoresistor. The side wall is provided with a movable cavity, the bottom of the movable cavity is fixed with a heating box, the inside of the heating box is fixed with a heating plate, the top of the movable cavity is fixed with a cooling box, and the inner wall of the cooling box is fixed with a heat insulation board , the outer walls on both sides of the cooling box and the heating box are jointly fixed with a plurality of partitions arranged at equal intervals. The advantage is that when dust appears on the surface of the monitor lens to hinder shooting, the light emitted by the light source will not be able to irradiate the photoresistor well, so that the resistance of the photoresistor will change, and then wind will be generated to clean the dust, so that the dust can be removed in time. Cleaning, so that the dust will not accumulate for a long time and make the shooting completely impossible, thus ensuring the normal use of the monitor.
