5results about How to "Meet drainage needs" patented technology

The invention discloses a three-dimensional visual design system for a farmland drainage system based on digital twinning, and relates to the field of hydraulic engineering. A point location generation module; the sequence generation module is used for screening to obtain a preparatory sampling point sequence of the farmland range; the water channel generation module forms a main drainage channel and an auxiliary drainage channel; the width setting module is used for setting the cross sectional areas of the main drainage channel and the auxiliary drainage channel; and the scheme determination module is used for calculating the construction workload of the total drainage scheme and taking the main drainage channel and the at least one auxiliary drainage channel generated by the total drainage scheme with the minimum construction workload as a final design result. By arranging the point location generation module, the sequence generation module, the canal generation module, the width setting module and the scheme determination module, the scheme capable of meeting the drainage requirement is obtained, and meanwhile the construction cost can be saved as much as possible through the scheme.

The utility model discloses a structure drift plate and curtain wall outward drainage structure, including the corrugated steel sheet, sand lime brick and sealant, the corrugated steel sheet front end is bent down and is sealedly connected with curtain wall outside through sealant, the corrugated steel sheet middle part is outwardly inclined and forms the drainage gradient, the corrugated steel sheet tail part is horizontally bent and is fixed on the structure drift plate through sand lime brick. The thickness of the corrugated steel sheet is not less than 1mm. The length of the corrugated steel sheet front end bent down part is not less than 50mm. The sticking place of the corrugated steel sheet and curtain wall outside realizes continuous and uninterrupted sealing through sealant. The utility model can adjust the outward inclination angle according to the height difference between the single layer curtain wall top and the drift plate top surface, thereby the adaptability is stronger, not only convenient construction, and the cost is low, can satisfy the need of display floor drainage, has good application and popularization value in the need of temporary upper structure drainage construction in the curtain wall installation process.

The application relates to the technical field of underwater vehicles, and discloses an internal phase change drainage system and an underwater vehicle. The internal phase change drainage system comprises a drainage device, a ballast water tank and a control unit. The drainage device comprises a first power unit and a pressure reduction unit. The first power unit is internally provided with a first storage chamber for storing liquid carbon dioxide. The pressure reduction unit is internally provided with a pressure reduction chamber. The ballast water tank has a containing chamber for containing water. The containing chamber is selectively communicated with the pressure reduction chamber. The control unit is in communication connection with the first power unit. The first power unit is suitable for converting liquid carbon dioxide into high-pressure supercritical carbon dioxide under the control of the control unit. After being pressure-reduced via the pressure reduction chamber, the carbon dioxide enters the containing chamber to drain water in the containing chamber. The drainage system disclosed by the application is safe, efficient and has high drainage capacity.

The application discloses a deformable roof structure, relates to the technical field of house building, and comprises two roof panels, the two roof panels are rotationally arranged on the top of a building, one of the roof panels is provided with a plurality of extension plates one, the other roof panel is provided with a plurality of extension plates two, a gap one for accommodating the extension plates two is arranged between two adjacent extension plates one, a gap two for accommodating the extension plates one is arranged between two adjacent extension plates two, the structure further comprises a driving source, the driving source is used for driving the roof panel to rotate, a sealing device is arranged in the roof panel, and the sealing device is used for sealing the corresponding gap one or the gap two. The application has the effect that the roof can be switched between a horizontal state and an inclined state.

The utility model relates to an anti-blocking device for a garden ditch. The sewage collecting well is arranged for the ditch, water on the ground can conveniently flow into the ditch to be discharged, the upper sewage collecting cage arranged in the sewage collecting well can collect sundries flowing into the ditch from the well lid, the lower sewage collecting cage can filter water flowing in the ditch again, heavy sundries such as silt in the ditch can be collected into the deposition bottom box, and therefore the sewer can be cleaned conveniently. According to the requirements of the length of the ditch and the drainage position, the sewage collecting wells are arranged on the ditch, the drainage requirement can be met, water in the ditch can be filtered and purified for multiple times, and accumulation and blockage of sundries are avoided. And the upper sewage collection cage and the lower sewage collection cage are both buckled in the sewage collection well and are convenient to take out for cleaning. The whole device is simple in structure, convenient to arrange, good in impurity removing and anti-blocking effect, convenient to maintain and manage and low in application cost.
