This invention relates to the field of construction elevator foundation construction technology, aiming to solve the problems of material waste caused by existing technologies that separately set the construction elevator foundation on the basement roof slab or set it on the basement floor slab through the roof slab. This invention provides a construction elevator foundation construction method based on the settlement of the basement foundation slab, including the following steps: Step 1: Determine the installation point of the construction elevator; Step 2: Settle the basement foundation slab at the selected installation point, construct a cushion layer on the base layer, and then construct a waterproof structural layer on the surface of the cushion layer; Step 3: Tie the reinforcement of the basement foundation slab; Step 4: Pre-embed drainage pipes; Step 5: Pour concrete for the basement foundation slab, using the basement foundation slab in the settlement space as the construction elevator foundation; Step 6: Install and inspect the construction elevator; Step 7: Dismantle the construction elevator; Step 8: Backfill the settlement pit formed between the construction elevator foundation and the basement foundation slab outside the settlement space.

This invention discloses a system and method for measuring and predicting electrical variables based on big data analysis, belonging to the field of data analysis technology. The method includes: retrieving power generation records from a photovoltaic power station; identifying and extracting target records; obtaining attribute and status indicators of the photovoltaic panels; calculating the attribute and status indicator values ​​of the photovoltaic panels during the power generation time to obtain the unit power generation of the photovoltaic panels; extracting target indicators from the attribute and status indicators; filtering from the complete set of photovoltaic panels to obtain a photovoltaic panel sample set; establishing a first set of the complete photovoltaic panel set and a second set of the photovoltaic panel sample set; calculating the warning coefficient of the photovoltaic panel sample set; and determining whether to issue a warning for the photovoltaic panel sample set. This invention analyzes historical power generation records in conjunction with multiple indicators of photovoltaic panels to issue warnings for the photovoltaic panel sample set, which helps to make the selected sample data more reasonable and reliable, and improves the accuracy of electrical variable measurement and prediction.

The invention provides an automatic edge wire discharging device, and belongs to the technical field of gabion box production equipment. The problems of high labor cost, high labor intensity, low production efficiency and poor safety due to the fact that the gabion box overlock forming machine depends on manual wire feeding are solved. The device comprises a V-shaped base plate, a pair of end plates, a baffle, a plurality of material stirring wheels, a main transmission shaft, a first driving mechanism, a push plate and a second driving mechanism. The V-shaped base plate comprises a flat plate and an inclined plate, the two ends of the baffle are connected with the end plates and are parallel to the inclined plate, and a cuboid space with a feeding port in the top end and a discharging port in the bottom end is formed and used for containing edge wires. The material stirring wheel is located below the cuboid space and tangent to the inclined plate, the material stirring wheel is installed on the main transmission shaft, a plurality of U-shaped notches are formed in the circumferential direction of the material stirring wheel, and the first driving mechanism drives the main transmission shaft to rotate and drives the U-shaped notches in the material stirring wheel to sequentially pass through the discharging port. The edge wire blanking device is mainly used for realizing automatic edge wire blanking and improving the production efficiency.

This utility model belongs to the field of knitting machine technology, specifically an adjustable weft knitting machine. It includes a weft knitting machine body, an adjusting seat fixedly connected to the body, and multiple bottom shells fixedly connected to the adjusting seat. A toothed ring is rotatably connected to the outer edge of the annular ring formed by the bottom shells. Each bottom shell contains a transmission component that is driven by the toothed ring. A top shell is fixedly connected to the upper end of each bottom shell, and an adjusting component that is driven by the transmission component is located within each top shell. This patent allows for the adjustment of all adjusting components using the toothed ring, thus solving the problem of individually adjusting the sinker triangles in weft knitting machines, requiring specialized tools, which is cumbersome, time-consuming, and labor-intensive. It greatly improves adjustment efficiency and reduces labor intensity. Furthermore, the toothed ring synchronously adjusts all adjusting components, resulting in good consistency and high accuracy.
