The invention discloses a combined-floating-block-type sea wave power generation system. The combined-floating-block-type sea wave power generation system comprises at least two floating blocks. The floating blocks are connected with a sliding rail on a cabin through a power rod in a sliding mode. The power rod is supported by a platform. The inner lateral side of the power rod is provided with teeth, and the inner lateral side is provided with a rack structure. An output gear of a speed-changing gear box is connected with a generator through a transmission shaft. When sea waves rise or drop, single-direction rotating of the transmission shaft is achieved through transmission accelerating of the rack structure and the speed-changing gear box, and therefore power is generated by the generator. The floating blocks are evenly distributed on the peripheral surface of the cabin, the cabin is fixedly supported on the platform, the upper portion of the cabin is covered and closed by a cover top, and the platform is provided with a foundation pile. The combined-floating-block-type sea wave power generation system improves sea wave use ratios, reduces energy consumption from the kinetic energy to the electric energy of the sea waves, and improves the efficiency of the generator.

The invention relates to a distraction device and a distraction device system, the distraction device is used for implementing distraction osteogenesis, and the distraction device comprises a shell comprising an accommodating cavity; a rotating shaft extending along the axial direction of the shell and rotatably accommodated in the accommodating cavity; a moving part comprising a first end and a second end which are opposite to each other, wherein the first end is contained in the containing cavity and arranged on the rotating shaft in a sleeving mode, and the second end is located outside theshell and used for being connected with human bones or tissue; and a magnetic rotor arranged on the rotating shaft and used for driving the rotating shaft to rotate around the central axis of the rotating shaft under the action of a first external magnetic field, so that the moving part moves relative to the shell along the axial direction of the shell. The distraction device can be integrally implanted into the body of a patient, the influence on the daily life of the patient is reduced, and the possibility of infection and falling is reduced.

The invention relates to a construction technique for a composite pile formed through broken stone consolidation by slurry. According to the construction technique, a pile hole is dug in a pile position firstly, and a broken stone cushion layer is laid at the bottom of the pile hole; then a prefabricated pipe pile with a slurry injecting pipe is implanted into the pile hole; broken stone is fed into the pile hole, and broken stone which continues to be fed into the pile hole is vibrated to be dense; a close cover is arranged on the upper portion of the pile hole, and valves are arranged on pipe bodies, stretching out to the upper portion of the close cover, of the slurry injecting pipe and a slurry outflow pipe; slurry is pumped into the pile hole through the slurry injecting pipe till the slurry in the pile hole overflows from the slurry outflow pipe, and when the slurry concentration of the slurry outflow pipe reaches the design demand, slurry injecting is stopped, and the valves are closed; and after natural curing is finished, the composite pile formed through broken stone consolidation by the slurry is obtained. The construction technique for the composite pile formed through broken stone consolidation by the slurry is simple, quick and efficient in construction, low in noise, vibration and impacting force during construction, stable in pile-forming quality and high in single pile bearing capacity. The construction technique for the composite pile formed through broken stone consolidation by the slurry is especially suitable for construction sites with a narrow field and pile foundation construction near large buildings or historic monuments and sites and has great economic and social value.

The invention discloses a construction method of an underground laminated double-pipeline common-well structure. Firstly, a waterproof cylinder is machined, then an excavation well is dug out, an upper pipe group and a lower pipe group are arranged in the excavation well, a plurality of stacked reinforcing rings are arranged on the peripheral wall of the excavation well to form a mud blocking cylinder, and the waterproof cylinder is arranged outside the mud blocking cylinder. The upper pipe group comprises a plurality of pipe joints, the upper pipe set arranged in the excavation well is calleda connection section, the pipe joints on the connection section are called connection pipes, the pipe joints on left side and the right side of the connection section are called connecting pipes, oneside of each connecting pipe is arranged in the excavation well and is connected with the connection section, and the other side of each connecting pipe is arranged outside the waterproof cylinder. The structure of the upper pipe group and the structure of the lower pipe group are the same except the connection section. According to the construction method, the upper pipe group and the lower pipegroup can be constructed in the same excavation well so that the construction time can be greatly shortened, the occupied area is small, the enclosed area of a road is small, and the influence on thelife of residents along a river is small. The method is used for conveying water back and forth in a water conservancy system.

The invention discloses a solar water heater with controllable heat collection tubes. The solar water heater comprises a support frame, a water storage tank is fixedly mounted on the upper portion of the support frame, a plurality of water outlets are formed in the water storage tank, a plurality of heat collection tubes are mounted on the water storage tank and mutually communicated, a control valve is mounted at the joint of each heat collection tube and the water storage tank and composed of a motor mounted outside and a valve plate slidingly mounted with the inside, a gear is mounted on the end portion of a spindle of each motor, an elongated slot is formed in the valve plate corresponding to each gear, and a rack is arranged on the wall of each sloth and matched with the corresponding gear. During use, if the heat collection tubes are damaged, a user can control the damaged heat collection tubes to be closed by controlling and regulating the valves, water leakage of the damaged heat collection tubes is avoided by isolating the heat collection tubes, times for maintaining and replacing the heat collection tubes are decreased, and impact on life of the user is reduced.

The invention relates to a dynamic house onsite reconstruction time and area determining method of a subsidence area, belongs to the field of mining-area house damage and onsite reconstruction, and solves the problems that a damaged village in a mining area is hard to resettle and house reconstruction needs long time. The land-surface dynamic subsidence process after exploitation of a mining areais analyzed, the subsidence deformation amount in the land surface caused by different exploitation sizes in the working face of the to-be-reconstructed area can be determined accurately, further, theresidual deformation amount of the land-surface subsidence area in the dynamic process is calculated quantitatively, compared with a house anti-deformation index, and the house onsite reconstructiontime and area in the mining process are determined. The anti-deformation house can be built as early as possible in the mining process, villagers whose houses are damaged by mining can live in new houses as early as possible, and the life quality of the villagers in the mining area is improved. The method can be used to scientifically and accurately guide house onsite reconstruction planning in the land-surface subsidence area in the dynamic mining process, and adversarial relation between workers and villagers in the mining area can be alleviated effectively.
