The invention discloses a mining self-pressurization intelligent wireless anchor cable dynamometer and a use method thereof, and aims to solve the problems existing in the use of an existing anchor cable dynamometer. The wireless anchor cable dynamometer comprises an oil cylinder outer body, a telescopic body, a first sealing ring, a three-way joint, a gauge outfit, an intelligent tray and a high-pressure oil pipe. The pressure release valve is arranged on the oil cylinder outer body, and the pressure release function can be achieved under the action of blasting impact; the manual pump pressurizes the interior of the oil storage cavity of the oil cylinder outer body through the three-way joint, and when the designed pre-tightening force is reached, the oil tightening valve can be rotated to seal oil into the oil storage cavity; a plurality of modules are arranged in the meter head, so that data acquisition, conversion and recording can be realized, and wireless transmission can be realized. The wireless anchor cable dynamometer is suitable for long-term monitoring and early warning of the axial force of the anchor cable in the coal mine tunnel, has the advantages of impact resistance, the stable test result, convenient data recording and transmission and convenient pressurization, and can analyze the stress conditions of the tray in different directions so as to better guide supporting construction and evaluate and check the supporting effect.

The invention discloses a method for smoothing output power of a direct-drive type ocean wave electric generator. On the premise of conducting direct electric generation through ocean wave energy, the purpose is realized that the power output by the electric generator is enabled to be smooth and steady through the method of adjusting the current iq of a shaft q of the electric generator, instead of additionally arranging electrical energy storage devices required by a regular ocean wave electric generation system. The prediction method of ocean wave heights based on an ARMA model is introduced to the calculation process of the ocean wave energy, the magnitude of the current iq of the shaft q of the electric generator is properly adjusted according to the work efficiency of the ocean wave electric generator, so that the process of converting the ocean wave energy into electric energy is enabled to be smooth and steady, and thus it is guaranteed that the output power of the ocean wave electric generator is enabled to be smooth and steady. According to the method for smoothing the output power of the direct-drive type ocean wave electric generator, on the one hand, the electrical energy storage devices required by the regular ocean wave electric generation system are omitted, and thus input cost is greatly reduced, on the other hand, the electrical energy quality output by the ocean wave electric generation system is improved, and the operation performance of parallel grid power transmission of a direct-drive type ocean wave electric generation system is improved.

The invention is suitable for the field of satellite broadband networks and provides a satellite broadband network service device, an operation platform and an authentication method. The satellite broadband network service device comprises a satellite route exchange module provided with different gateways and responsible for satellite broadband network access business; and an authentication service module connected with the satellite route exchange module and providing local authentication service for different gateways. The satellite broadband network service device, the operation platform and the authentication method solve the problems of an existing satellite broadband network route exchange device that the access mode is single, the power consumption is high, data can be lost easily, and there is no good for stable data transmission. The satellite broadband network service device, the operation platform and the authentication method have the advantages of the following two aspects that different gateways are available, the access mode is no longer single, and the different networks can be accessed easily; in addition, the authentication server is stripped to be the single authentication service module, the separation of data management and networking service is realized, and the stable data transmission is facilitated.

The invention discloses an assembly line for assembling a water control valve. The assembly line for assembling the water control valve structurally comprises water control valve assembling equipment,the water control valve, a roller assembly line body, supporting frames, universal wheels and a bottom supporting plate, wherein the two sides of the bottom of the roller assembly line body are perpendicularly connected with the supporting frames. Compared with prior art, the assembly line has the effective effects that the water control valve can be centrally placed on a conveying belt to be conveyed, and the water control valve can be conveyed to the position under the water control valve assembling equipment so that the accurate assembling rate of the water control valve can be increased;a chain wheel is of an assembled structure and can adapt to loose chains, the chains can be supported, and chain links of the chains do not need to be increased or decreased; and by means of the arrangement of supporting rollers, a triangular area formed between two rollers can be made up, the conveying belt in the triangular area can be supported, the situation that the water control valve fallsinto the triangular area in the conveying process is avoided, the conveying belt is prevented from being damaged due to large gravity, and the service life of the conveying belt is prolonged.
