The invention provides a rapid-slow flow smooth transition flow diversion system for a riverway intersection area. The structure of the rapid-slow flow smooth transition flow diversion system for the riverway intersection area is as follows: a hydraulic jump energy dissipation section is arranged on a rapid flow channel in front of intersection of two channels, and a streamline channel wall is arranged between the hydraulic jump energy dissipation section on the rapid flow channel and a slow flow channel; a jet flow control structure is composed of a fish mouth and a flow diversion wall, wherein the flow diversion wall is arranged at the top end of the fish mouth and is parallel with the slow flow channel; the fish mouth is arranged at an intersection point of the connection of the streamline channel wall and the slow flow channel and extends toward a slow flow channel center and extends to a stable flow diversion channel. The rapid-slow flow smooth transition flow diversion system for the riverway intersection area has the advantages that the phenomenon that large standing waves are formed when rapid flow directly enters the slow flow channel can be avoided, and channel flood discharge is benefited; the direction of the flow of the rapid flow channel can be changed stably, and the form of a flow line is changed smoothly; flow separation and vortexes are weakened and even eliminated, and the actual flow discharge area is increased; the jet flow control structure effectively lowers the water level of an affluxion mouth; the channel design flood discharge flow quantity is guaranteed, and the water level of the affluxion mouth is effectively controlled; and the rapid-slow flow smooth transition flow diversion system for the riverway intersection area is beneficial to popularization in a large area in areas with limited land and in city flood-prevention projects, and the expropriation of the land is greatly reduced.

The invention relates to an outdoor 500kV HGIS power distribution device structure and solves a disadvantage that practical demands can not be satisfied by an HGIS equipment arrangement structure in the prior art. The outdoor 500kV HGIS power distribution device structure comprises the HGIS equipment and a framework assembly, wherein the HGIS equipment comprises an incoming wire breaker, a middle breaker and an outgoing wire breaker which are sequentially and linearly arranged, a first end of the incoming wire breaker is equipped with an incoming wire casing, a tail end of the incoming wire breaker is equipped with a first bus casing, a first end of the middle breaker is connected in parallel with the first end of the incoming wire breaker through a branch bus, a tail end of the middle breaker is equipped with an outgoing wire casing, a first end of the outgoing wire breaker is connected in parallel with the tail end of the middle breaker, and a tail end of the outgoing wire breaker is equipped with a second bus casing. According to the outdoor 500kV HGIS power distribution device structure, not only can a vertical dimension of a 500kV HGIS power distribution device be effectively compressed, incoming / outgoing wire leading modes are optimized, and the framework and crossbeam arrangement structures are simplified.

The embodiment of the present invention relates to a sewage treatment device and a sewage lifting system. The sewage treatment device includes: a water inlet pipe, a solid-liquid separation tank, a one-way filter, a cut-off float, a water collection tank, a sewage pump and a water outlet pipe; solid-liquid separation The tank has a water inlet, a filtered water outlet and a sewage outlet; the sewage pump includes a pump body, a first connecting pipe and a second connecting pipe; the first connecting pipe is respectively connected to the one-way filter and the pump body; the second connecting pipe is connected to the pump When collecting water, the sewage flows into the solid-liquid separation tank from the water inlet pipe, and after being filtered by the one-way filter, the liquid part passes through the sewage outlet, the first connecting pipe, the pump body and the second connecting pipe into the water collection tank; the solid residue in the sewage is filtered by the one-way filter in the solid-liquid separation tank; when draining, the sewage pump starts to work, and the sewage in the water collection tank is pumped out by the second connecting pipe, pump body, The first connecting pipe and the one-way filter enter the water collection tank, and then are discharged from the outlet pipe through the sewage outlet.

The invention provides a fracturing pump truck driven by a turbine engine, which comprises an engine, a fracturing pump, pipelines and the like. A traditional large and heavy diesel engine is replaced by the turbine engine which is small in size, light in weight and high in power, the total output power of a single fracturing pump truck can be more than 4000hp under the requirements of limited integral vehicle weight. The fracturing pump truck driven by one turbine engine is equivalent to the fracturing pump truck driven by two traditional diesel engines, so that output power of unit operating area is improved, more labor and materials can be saved in transport and specific constriction operations of fracturing equipment, land requisition and operating area are reduced, and construction efficiency is improved. Further, the turbine engine can also use various gaseous and liquid fuels and is especially suitable for shale gas exploitation.

The invention discloses a data mining-based prediction method for electromagnetic environment parameters of a power transmission line. The method comprises the following steps of (1) collecting data;(2) partitioning the data; (3) analyzing a relationship among the electromagnetic environment parameters; (4) analyzing a relationship between a spatial electric field and an ion current parameter; (5) analyzing main factors influencing an electromagnetic environment; and (6) predicting the electromagnetic environment parameters and spatial electric field parameters. By applying the method, line parameters such as a wire type, a wire splitting interval, an inter-polar distance and the like can be further optimized in a line design stage; a more environment-friendly power network development mode is realized; power transmission corridors are reduced as far as possible; land acquisition and construction costs of the line are reduced; and the method has major engineering practical values.
