The invention discloses an aquaculture tail water treatment device and belongs to the technical field of tail water treatment, the bottom of a culture pond is conical and provided with an adjusting hole penetrating through the bottom, an in-pond sewage suction pipe is close to the bottom and extends upwards, and the side face of the in-pond sewage suction pipe is connected with a sewage discharge pipe. A conical adjusting block and a lifting device are arranged between the adjusting hole and the sewage suction pipe, the distance between the adjusting hole and the sewage suction pipe can be adjusted, the suction force of the sewage suction pipe is changed according to the Bernoulli principle, layered cleaning is achieved, a water outlet of the sewage discharge pipe is communicated with the primary sedimentation tank through a flow guide pipe inclining downwards, a water disturbing impeller is arranged at the water outlet, water flow rotates in one direction, and sewage accumulation is avoided. A biological filter dam is arranged in the middle of the primary sedimentation tank, and a filter cavity is formed in the dam, so that dirt can be isolated, water is purified, water quality is improved, and the water is more suitable for survival or cyclic utilization of cultured organisms. The device is reasonable in overall structure and capable of effectively treating aquaculture tail water and maintaining a good aquaculture environment.

The utility model discloses a building noise reduction enclosure device which comprises two enclosure frames, the two enclosure frames are attached to each other, and mounting notches are formed in the surfaces of the sides, away from each other, of the enclosure frames. Flame-retardant fiber sound-absorbing plates and aluminum honeycomb sound-absorbing plates are fixedly embedded in the outer sides and the inner sides of the mounting notches correspondingly, a plurality of sponge sound-absorbing balls adhere to the surfaces of the sides, away from each other, of the two flame-retardant fiber sound-absorbing plates correspondingly, and stand columns are arranged on the left side and the right side of the fence frame correspondingly; the left surface and the right surface of the fence frame located on the rear side are fixedly connected with the surfaces of the corresponding sides of stand columns correspondingly, and sliding grooves are formed in the surfaces of the corresponding sides of the stand columns. The noise insulation device is simple in structure and convenient to disassemble and assemble, the height can be adjusted according to the use requirements of workers, noise of a construction site can be effectively insulated and adsorbed, and the situation that normal life of nearby residents is affected due to too large noise is avoided.

This utility model discloses a decorative wall panel with good noise reduction effect, belonging to the technical field of decorative wall panels. It includes a wall panel body, with outer shells fixedly connected to both sides of the wall panel body. A locking block is slidably engaged within the outer shell. When installing this decorative wall panel, the operator places the wall panel body in a suitable position and pushes the locking block to slide within the outer shell. The locking block pushes the connecting plate to move, causing a first spring to retract and simultaneously pushing the column upwards, causing a second spring to retract. After the locking block is fully engaged with the steel frame, the second spring returns to its original position and pushes the column downwards until the column is fully engaged with the slot on the locking block. This facilitates quick installation of the wall panel body, preventing the need for complex and tedious installation processes that waste manpower and resources, reduce installation efficiency, and improve the ease of use of the decorative wall panel.

The present invention belongs to the field of electric power technology, and particularly relates to a peak-shaving and frequency-regulating method for a clean energy system based on demand-side management and multi-energy complementarity; the present invention describes the uncertainty of wind, light output and load forecasting based on the opportunity constraint method, and converts the constraint conditions containing uncertain factors into deterministic equivalent classes; establishes a load demand response model according to the price elasticity coefficient to achieve the first peak-shaving; performs the second peak-shaving through energy storage; determines the primary frequency regulation safety constraint index of the hydropower unit, reserves the frequency regulation standby, establishes the frequency regulation constraint index by using the primary frequency regulation capacity of the hydropower unit, and accurately calculates the primary frequency regulation standby capacity; based on demand-side management and multi-energy complementarity, uses the above-mentioned peak-shaving method and frequency regulation method, and arranges the output of each energy source with the goal of minimizing net load fluctuation and minimizing abandoned energy; the present invention motivates users through demand-side management, reduces the load peak-to-valley difference and the difficulty of peak-shaving from the power supply side, and also avoids affecting the normal life of consumers during peak-shaving and frequency regulation.
