Weather forecast-based maximal current carrying capacity prediction method of overhead transmission line

The invention relates to a weather forecast-based maximal current carrying capacity prediction method of an overhead transmission line, and the method comprises following steps of S1 collecting a position where the transmission line is located and weather data of past years in the local district; S2 regression analyzing a relation between ambient temperature, wind speed, wind direction and solar radiation quantity of the position on which the transmission line is located and weather data of the local district; S3 predicting a weather condition on the position where the transmission line is located through a formula according to the weather forecast of the local district of the transmission line; and S4 substituting the predicted weather condition in step S3 in a calculation formula provided in the international standard IEE738-2006 to calculate the maximal current carrying capacity prediction value of the transmission line. Against for the problem for predicting the maximal current carrying capacity of the traditional transmission line, by establishing the associated link between the on-site weather condition and the weather forecast data, the maximal current carrying capacity of the transmission line is predicted by utilizing the weather forecast data.

Method for automatically adding additional number when sending short message to personal handy phone and mobile terminal

The invention discloses a method for automatically filling an additional number by sending a short message to a personal handphone system and a mobile terminal. The method comprises the following steps that: after the short message editing is finished, the telephone number information of a short message receiver is extracted from a client module; a number information judgment module 1 of a service processing module judges whether the extracted telephone number is a mobile phone number or a personal handphone system number added with a personal handphone system additional number; if yes, the short message is directly sent out; otherwise, a number information judgment module 2 of the service processing module judges whether the extracted telephone number contains a district number; if the district number is contained, the personal handphone system additional number extracted from the storage module is automatically added in front of the district number; if the district number is not contained, a local district number extracted from a storage module is automatically added to the extracted telephone number; the personal handphone system additional number extracted from the storage module is automatically added in front of the district number by a calling number forming module of the service processing module; and the short message is sent out by a short message service processing module of the service processing module. The method simplifies the operation and brings great convenient for a user.

Supporting method for superhigh sections of two ends of fully-mechanized mining face

InactiveCN105221173ASafe and efficient passageEasy to passMine roof supportsElectrical controlEngineering
The invention relates to a coal mine supporting technology and provides a supporting method for superhigh sections of two ends of a fully-mechanized mining face, aiming at solving the supporting problem of the superhigh sections of local district roadways of intake and return airways. When driving to the superhigh sections, workers lower each hydraulic support to a lowest position, mount a hydraulic telescopic supporting device to the top of the hydraulic support and connect the hydraulic telescopic supporting device to a control device nearby a supporting frame handle through a hydraulic pipeline, and a hydraulic source is a pump station using a matched working face, so that safe and rapid operation is achieved, a fully-mechanized method for passing the superhigh sections flexibly, safely, efficiently, conveniently and rapidly is achieved, operation is facilitated, cost is saved, a high-strength high-altitude operation method that personnel nog above 2.5-meter shed beams during shed erecting construction is avoided, and nogging and shed erecting timbers and shed erecting cost are decreased. A power source and electrical control equipment do not need to be added; on the premise of not upgrading into ultrahigh supports, tasks which cannot be completed by original supports can be completed by additional mounting of a set of equipment.

Welding device for socket pipe with plastic-wound structural wall and connecting technology thereof

ActiveCN105269806AFirmly connectedConsistent pressure intensityEngineeringMechanical engineering
The invention discloses a welding device for a socket pipe with a plastic-wound structural wall and a connecting technology thereof. An inner cavity extruder is arranged on a right-side rail of a spindle box. The inner cavity extruder head of the inner cavity extruder penetrates through a spindle hole of the spindle box. An inner scraper which can move freely is arranged at the end of the inner cavity extruder head. Two upper-side outer clamping jaws are fixedly provided with upper semicircular dies, and two lower-side outer clamping jaws are fixedly provided with lower semicircular dies. The inner scraper extrudes, scrapes and forms the inner cavity of a socket head formed through rotational moulding when the socket head formed through rotational moulding is welded with the pipe with the plastic-wound structural wall, and cooling and setting are conducted through air. Compared with the prior art, the pipe with the plastic-wound structural wall and the socket head formed through rotational moulding are connected firmly, the pressure intensity of a whole pipe system is maintained the same, cracking or water seepage of local districts of the pipe system is avoided, secondary pollution of underground water is prevented effectively, industrialized production of the pipe with the plastic-wound structural wall and the socket head is achieved, line production is achieved, and the work efficiency is improved by 50%.
