The invention discloses a track cleaning maintenance truck which comprises a dual chassis for roads and tracks, a track wheel system, a track cleaning execution mechanism, a drying mechanism and a protective oil coating system. The track wheel system is provided with anti-rollover mechanism. The track wheel system is connected with the chassis through a hydraulic lifting mechanism, the anti-rollover mechanism is fixed between two track wheels, and the track cleaning execution mechanism is fixed under the chassis through pins. The track cleaning maintenance truck is modified on the basis of the dual-use chassis for roads and tracks, difficult problems of high requirements of track maintenance quality and small surrounding space of tracks are solved, and functions of on-track running, synchronous descaling to five work faces of two tracks, track work face oil stain cleaning and automatic oiling to the track work faces can be realized. By the track cleaning maintenance truck, requirements for automatically maintaining tracks are met, workload in manual maintenance is lowered, maintenance quality can be improved, and reliable guarantee is provided for service of the tracks.

The invention discloses a method and a system for addressing short-message gateways and short-message gateways. In the method, all the short-message gateways in a short-message system respectively exchange attributive number routing information to obtain identity marks and attributive address information of the short-message gateways of all terminals of all networks; a corresponding short-messagenumber routing list is generated; when the short-message gateway of a transmitting terminal receives a short message transmitted by the transmitting terminal, the identity mark of a receiving terminal which corresponds to the short message is obtained; and the address information of the short-message gateway of the receiving terminal is obtained from the short-message number routing list. All embodiments can effectively overcome the defects of high maintenance cost, large maintenance workload, poor expansibility, low operating efficiency and the like in the prior art for reducing the maintenance cost and the maintenance workload and enhancing the expansibility and the operating efficiency.

The invention belongs to the technical field of analysis and computation of transmission losses of the power grid in the electric system and particularly relates to a method for counting equipment of the power grid and computing transmission losses on the basis of on-line theoretical transmission loss computation. The method includes: building gate circuits or gate transformers at the boundary of a domination area of a power grid company, automatically counting and updating circuits and transformers involved in the on-line theoretical transmission loss computation on the basis of the topological structure of the power grid, and accordingly, computing distribution of theoretical transmission losses and computing policy for reducing losses. By the method, all equipment involved in transmission loss computation can be automatically determined by manually maintaining the gate circuits and the transformers at the boundary of the domination area of the power grid company only. Besides, when the method is compared with the conventional manner of manual maintenance, work load is greatly reduced, the method can adapt to change of the power grid structure automatically, and availability and accuracy of on-line theoretical transmission loss computation and loss reduction policies for the power grid are improved.

The invention relates to a low-temperature environment sunlight heat extraction power generation device, relates to a power supply technology of an electric power online monitoring device, and aims tosolve the problem that an existing heat extraction power generation device is limited in application range and low in heat absorption efficiency. A heat collecting pipe of the device is a double-layer transparent tube, the double-layer transparent tube is vacuumized, the top of the heat collecting pipe is open, and the bottom is closed; power generation pieces are thermoelectric power generationpieces; the power generation pieces are arranged in a middle part of the heat collecting pipe; the power generation pieces are clamped between a hot end radiator and a cold end radiator; the bottom ofa cold end thermal isolation piece is fixed to the cold end radiator, the top of the cold end thermal isolation piece extends to the open end of the heat collecting pipe, and two side walls of the cold end thermal isolation piece are in full contact with an inner wall of the heat collecting pipe; and the top of a hot end thermal isolation piece is fixed to the hot end radiator, the bottom of thehot end thermal isolation piece extends towards the bottom of the heat collecting pipe and keeps a certain distance from the bottom of the heat collecting pipe, and two side walls of the hot end thermal isolation piece are in full contact with the inner wall of the heat collecting pipe. The beneficial effects are that the range of application is wide, and the heat absorption efficiency is high.

The invention discloses a device for wiping a track. The device mainly consists of an upper base (1) provided with baffles respectively at the two sides, an upper spring (2), a reversed L-shaped guide rod (3), a bearing (4), two side bases (5), a cotter (6), a side spring (7) and wiping materials (8), wherein the wiping materials (8) are respectively fixed on the surfaces where the upper base (1) and the two side bases (5) are contacted with the track; and the two side bases (5) are respectively arranged at the two sides of the upper base (1) by the reversed L-shaped guide rod.
