6results about How to "Reduce scour force" patented technology

This invention relates to an anti-scour device for a wind turbine monopile, comprising a first anti-scour component, tire components, and a reinforcing component. The first anti-scour component is mounted on a base and includes a bracket and a first anti-scour net. The bracket is arranged around the periphery of the wind turbine monopile's pole, and the first anti-scour net is disposed on the side wall of the bracket, spaced apart from the pole to form a receiving space. Multiple tire components are disposed within the receiving space and are connected and fixed to the bracket via cables. The reinforcing component includes a sleeve and multiple tie rods. The sleeve is fitted around the periphery of the pole, and the multiple tie rods are spaced apart along the circumference of the pole, with both ends of the tie rods connected and fixed to the sleeve and the bracket, respectively. Under the anti-scour action of the first anti-scour component and the tire components, the sand and gravel layer surrounding the wind turbine monopile can be protected, preventing or reducing seawater erosion of the sand and gravel layer and the formation of scour pits, ensuring that the sand and gravel layer can provide sufficient load to the base and guaranteeing the stability of the wind turbine monopile.

This invention discloses a riverbank protection device and method, specifically relating to the field of riverbank protection technology. It includes a riverbank protection body, a planting area, and an ecological flow guiding component. The ecological flow guiding component comprises multiple alternately arranged flow guiding elements and ecological frames. Each flow guiding element has a water storage tank inside, which provides moisture to the soil within the ecological frames and planting area on both sides of the flow guiding element. The flow guiding element also includes a flow guiding channel located at the upper end of the water storage tank. The flow guiding element can guide the water flowing into it according to the water volume stored in the water storage tank. By incorporating a water storage tank and a flow guiding channel within the flow guiding component, this invention can collect and store rainfall runoff during non-flood seasons. During flood seasons, when water levels are too high, it can automatically guide excess water to downstream areas or the river channel, preventing excessive accumulation in the water storage tank and thus avoiding additional pressure on the riverbank. The water stored in the water storage tank can provide a continuous water supply to the slope protection plants during drought periods.

This utility model discloses a prefabricated structure for the aluminum outlet of a tilting furnace, relating to the technical field of tilting furnace accessories. The utility model includes a mounting plate, with a jointed flow port fixedly connected to one side of the mounting plate. A furnace-turning flow channel is provided on the surface of one side of the jointed flow port. A flow guiding mechanism is provided on one side of the mounting plate. This utility model, by adopting a straight-lined square channel, significantly increases the aluminum flow rate compared to traditional circular rotary joints, meeting the needs of large-capacity tilting furnaces and improving production efficiency. The straight flow channel design reduces turbulence formation during aluminum flow, reducing the scouring force on the jointed flow port and the furnace-turning flow channel, thereby reducing refractory wear and extending the service life of the equipment. Through the cooperation of a clamping plate, arc-shaped groove, arc-shaped positioning block, and positioning baffle, rapid positioning and installation of the furnace-turning flow channel are achieved, simplifying the installation process and improving operational convenience.

The utility model relates to the technical field of filtering equipment, and discloses a coal-fired power plant boiler make-up water raw water filtering device which comprises a filtering bin, a first filtering net is arranged in the filtering bin, one side of the first filtering net is fixedly connected with a collecting box, and a protection assembly and a recycling assembly are arranged on the outer wall of the first filtering net. The protection assembly comprises a plurality of second springs, the second springs are located on the outer wall of the first filter screen, a plurality of first connecting blocks and second connecting blocks are fixedly connected to one side of the first filter screen, a fixing block is slidably connected to the outer wall of each second connecting block, and a second filter screen is fixedly connected to one side of each fixing block. One end of the second spring is fixedly connected to the outer wall of the second connecting block, and the other end of the second spring is fixedly connected to the inner wall of the fixing block. According to the device disclosed by the utility model, the scouring force of water flow to the surface of the filter screen I is relieved through the stretching of the spring I and the compression of the spring II, so that the effect of protecting the filter screen I is achieved, and the protection property of the device to the filter screen I is enhanced.

The utility model relates to the technical field of land engineering, concretely is a kind of side slope protection structure. Including side slope component, walkway component, water guide component, the side slope component includes side slope main part, the walkway component includes walkway side wall one, the water guide component includes water guide fender, the top of side slope main part is fixedly connected with side slope top layer by embedded reinforced concrete, the front end of side slope main part is fixedly connected with side slope bottom layer by cast-in-place concrete inlay, the top of walkway side wall one is fixedly connected with installation base plate by embedded bolt, the inside of stable protection layer is opened along its length direction and is penetrated with drainage top groove. Slow-flowing tank distributes water body to each longitudinal water guide groove, avoids local water guide groove water flow overload, further reduces the impact force of water flow to water guide fender and side slope main part, shunt to the top end face of water guide fender, by shunt design, avoid single water flow concentrated impact water guide fender, reduce local stress load.
