The invention relates to a test specimen fixture for ultrasonic vibration assisted grinding/polishing, and belongs to the field of precision machining and ultra-precision machining. The test specimen fixture comprises an ultrasonic generator, a piezoelectric ceramic transducer, a conical amplitude-change pole, a workpiece clamping system and a trimming ring. Alternating current is converted into ultrasonic-frequency electric oscillation signals by the ultrasonic generator, and the ultrasonic-frequency electric oscillation signals are transmitted to the piezoelectric ceramic transducer by a collector ring. The ultrasonic-frequency electric oscillation signals are converted into ultrasonic-frequency mechanical vibration by the piezoelectric ceramic transducer. The small amplitude of the vibration outputted by the transducer is magnified by the conical amplitude-change pole, and the vibration with the magnified amplitude is transmitted to the workpiece clamping system, so that workpieces can ultrasonically vibrate in ultra-precision grinding/polishing procedures. The test specimen fixture has the advantages that the test specimen fixture is compact in structure, simple in operation and high in efficiency and applicability; the machining precision and the surface quality of each workpiece can be obviously improved; grinding/polishing conditions further can be improved, for example, cutting force and cutting heat can be reduced, and vibration can be eliminated or suppressed; the durability of a grinding disc and the durability of polishing cloth can be improved, and the like.

The invention discloses a method for reducing water on urban streets which builds rainwater accumulation devices in residential quarters or other public areas such as squares, parks and grassy areas without affecting the traffic, wherein the rainwater accumulation devices are communicated with urban sewerage backbone network through drainage branch pipes with drainage flow regulating devices. When it rains, the rainwater on areas except the urban streets firstly flows in the rainwater accumulation devices, then water in the rainwater accumulation devices is drained to the urban sewerage backbone network designedly and organically according to the flow set by the drainage flow regulating devices to outflow. The constant flow organically drainage is carried out according to different zones and different time intervals along the rainwater accumulation devices, the rainwater branch pipes and the backbone pipes so as to solve the conflict that the drainage capacities of the drainage backbone pipes and river channels are not enough as rainwater is drained intensively in short time, and reduce the influence of standing water to the work and life of people.

In the invention, for the power needing energy storage, by utilizing various equipment and facilities of a hydraulic power station and building various pumping equipment and facilities, part of water behind the dam of the hydraulic power station is pumped to flow back to the region ahead the dam of the original reservoir, thereby achieving the purpose of energy storage. Energy resources such as kinetic energy, potential energy, pressure energy and the like generated by the newly mixed water ahead the dam are converted into the mechanical energy of generating equipment and then converted into stable electric energy to be sent out through the network. By establishing a great electric energy storage platform for combining a plurality of reservoirs and stations with other hydraulic power stations, the invention can effectively solve the problem of energy storage of power and especially green power, thereby promoting the healthy development of the green power in larger scale, higher speed and wider range. Moreover, an extra-high voltage power transmission technology, a smart grid technology and other related technologies are used for realizing a good situation of adjustable, controllable and sustainable power generation, power storage, power utilization and power transmission and transformation, thereby providing services for economic and social development.

The invention relates to a float-type sludge scraping and suction system and a sludge scraping and suction operation method. The system is composed of a secondary sedimentation pond body, a float boat bridge crane and a sludge suction and scraping device. The secondary sedimentation pond body is used for separating sediment sludge in a pond, and for removing pond bottom sludge. The float boat bridge crane drives the sludge suction and scraping device to perform reciprocation movements in the secondary sedimentation pond. The suction and scraping device sucks and scraps sediment sludge at the bottom of the secondary sedimentation pond. The overall body of the secondary sedimentation pond is a rectangular box body. Reflux canals are arranged on the two sides of the secondary sedimentation pond body, and are arranged along the two sides of the secondary sedimentation pond body. The reflux canals recovers the sediment sludge at the bottom of the secondary sedimentation pond, and discharges the sludge out of the secondary sedimentation pond. The system provided by the invention has the advantages of scientific design, simple structure, easy operation, small volume, smooth continuous travelling, low noise, convenient maintenance, low maintenance cost, automatic travelling correction, simple structure, reasonably layout, low investment, fast effect, low operation cost, convenient management, and wide application range.
