The invention relates to a vehicle fore cabin structure and a vehicle. The fore cabin structure comprises two longitudinal beams arranged at an interval along the left-right direction, two wheel covers arranged at an interval along the left-right direction, two wheel cover reinforcing plates respectively arranged on the two wheel covers, and a gutter channel, wherein the two longitudinal beams arelocated between the two wheel covers, and the longitudinal beams are uniform-section longitudinal beams; the gutter channel extends between the two wheel covers, the upper end of each wheel cover reinforcing plate is connected with the gutter channel, the lower end of each wheel cover reinforcing plate is connected with the corresponding longitudinal beam, the section shape of the lower end of each wheel cover reinforcing plate is matched with the section shape of the corresponding longitudinal beam, and a lower end of each wheel cover reinforcing plate is used for installing a vehicle auxiliary frame. According to the structure, a lower end of the wheel cover reinforcing plate can be connected to any position in the length direction of the longitudinal beam, for vehicle types with different axle distances, the vehicle auxiliary frame can be installed at different positions without replacing the wheel cover reinforcing plate, the multi-vehicle-type platformization sharing rate of thevehicle forecabin structure is increased, and production and development cost is reduced.

The invention discloses a flower nursery stock cultivation substrate composed of components of, by weight: 14 to 16 parts of stalk, 11 to 13 parts of corncob, 7 to 9 parts of sorghum shell, 7 to 9 parts of serrago, 6 to 8 parts of tenebrio molitor manure, 4 to 6 parts of perlite, and 4 to 6 parts of maifanite. The components are first prepared into a dry substrate, and the dry substrate is fermented with cultivated a probiotic flora liquid, such that the cultivation substrate is obtained. According to the invention wastes produced in agricultural and forestry productions are prepared into the cultivation substrate used for cultivating flower nursery stocks. As a result of experiments, the cultivation substrate has a similar or even better cultivation effect than a peat substrate. The result proves that the flower nursery stock cultivation substrate provided by the invention can completely replace peat. The cultivation substrate and the preparation method provided by the invention adapts to local conditions. With the substrate and the method, a large amount of agricultural and forestry waste resources are utilized. The development and production costs are low. The cultivation substrate is a clean and environment-friendly substrate which can be circularly utilized. With the cultivation substrate, a conflict between rapidly increased requirement of current flower nursery stocks on cultivation substrates and gradually exhausted peat resources can be solved.

The invention discloses a method for preparing bacterium-algae cells through a two-wheel coculturing and flocculation method. The method comprises the steps of 1, conducting the first cycle of coculturing on rice endogenous pantoea which is added for the first time and chlorella under illumination, so that after culturing is ended, a bacterium-algae coculturing solution of the first cycle is obtained; 2, supplementing rice endogenous pantoea which is added for the second time into the bacterium-algae coculturing solution of the first cycle, conducting the second cycle of bacterium-algae coculturing under illumination, so that after culturing is ended, a bacterium-algae coculturing solution of the second cycle is obtained; 3, conducting flocculation collection treatment on the bacterium-algae coculturing solution of the second cycle, so that the bacterium-algae cells are obtained. According to the method, bacterium-algae coculturing is conducted through the rice endogenous pantoea and the chlorella, the growth rate of the algae cells is raised, biomass of the algae cells is increased, meanwhile, flocculation performance of the algae cells is improved, application of chemical flocculating agents and toxic harm to the algae cells are reduced, algae cell collection efficiency is improved, algae cell collection cost is lowered, and thereby industrial production and development and application cost of chlorella are remarkably lowered.

The invention provides a high-precision real-time online multiphase flowmeter for oil fields. The multiphase flowmeter includes a safety valve, a gas-liquid separator, a float oil-gas three-way regulating valve, a liquid flowmeter, a pressure gauge, a water content measuring instrument, a gas flowmeter, valves and pipelines. The gas-liquid separator separates the medium from gas to liquid; the float oil-gas three-way regulating valve ensures the measurement accuracy of the liquid flowmeter and gas flowmeter; the moisture content measuring instrument uses a differential pressure transmitter to measure the moisture content in the liquid. The multiphase flowmeter of the present invention can measure the moisture content of liquids in real time, accurately, quickly and effectively, and the measurement error of the moisture content is less than ±2%. Then, according to the measurement results of the liquid flowmeter and the gas flowmeter, through computer processing, the oil and water can be obtained. , Gas production value. The multiphase flowmeter of the invention can implement production optimization, improve oilfield work efficiency, save oilfield production and development costs, and is beneficial to oilfield management and process control.

Currently, movable parts in a coil nail device of a coil nail machine can not be installed in a protecting cover, and the phenomenon that operators are hurt frequently occurs. According to the safe coil nail device of the coil nail machine, non-universal elements such as a duplex slide cylinder support, a bearing support, a speed reduction motor support, the protecting cover, a coupler and a coil nail shaft are manufactured through universal elements such as a duplex slide cylinder, a direct-current speed reduction motor, a constant-current drive circuit of the direct-current speed reduction motor and a bearing, then the safe coil nail device which is simple in structure, stable in running, small in size, capable of producing high-quality coil nails and free of hurting the operators can be assembled, and the safe coil nail device is used for replacing conventional coil nail devices which are widely used at present.

The invention discloses a SDN-based load balancing device and a method thereof. The load balancing device comprises a load balancing controller and a plurality of load balancing switches. The plurality of load balancing switches are connected to the load balancing controller through a base plane to establish an openflow channel, the load balancing controller is used for shunting decision and load monitoring. The load balancing switch parses and transmits or discards data traffic according to instructions issued by the load balancing controller. The SDN-based load balancing device shunts a control plane and a forwarding plane of the load balancing device so as to reduce the complexity of a load balancing system, improve the system maintainability, realize multi-device interconnection cascade, and reduce the development and production cost.
