The invention discloses a reinforced concrete bonding segment drawing fatigue and corrosion coupling testing device and a testing method. The reinforced concrete bonding segment drawing fatigue and corrosion coupling testing device comprises a limiting plate and a corrosion box, the limiting plate is supported by stand columns and horizontally arranged, the corrosion box is fixed to the limiting plate and used for simulating a drying and watering cycle environment, reinforced concrete and a corrosion medium are contained in the corrosion box, a through hole allowing the reinforcing steel bar free end of reinforced concrete to penetrate is formed in the middle of the limiting plate, an anti-percolator is arranged in the through hole, and a fatigue tensioning and pressing device for enabling the reinforcing steel bar free end of the reinforced concrete to be tensioned downwards in the axial direction is arranged below the limiting plate or above the corrosion box. A conductive sheet is arranged in the corrosion box, and the conductive sheet and the reinforcing steel bar of the reinforced concrete are electrically connected with a direct-current instrument through corresponding wires. A durability test of a material under the action of harmful ion erosion and fatigue coupling can be simulated.

An orientation automatic regulating system for a deep-sea autonomous underwater vehicle (AUV) docking platform comprises an acoustic doppler current profilers (ADCP), a electronic compass module, a horn, a steering mechanism and a control module for steering. The steering mechanism comprises a supporting plate, a base connecting bracket, an underwater electric motor, a bearing retaining casing, an electric motor coupling shaft with a flange at the top end, an upper thrust bearing, an upper deep groove ball bearing, a lower thrust bearing, a lower deep groove ball bearing, a bearing axial race snap, a first sleeve and a second sleeve, wherein the underwater electric motor and the bearing retaining casing are in a coaxial manner. According to this arrangement, the conditions of deep-sea docking are fully considered. The automatic steering of the horn before docking according to the information of external factors, such as ocean currents and the like and the automatic locking of the horn after the direction is oriented can be achieved in the process of docking, so that the influence of the external factors, such as ocean currents and the like can be reduced. The orientation automatic regulating system has the advantages of being greatly intelligent in control, simple in structure, easy to maintain and good in reliability. Accordingly, the success rate of deep-sea AUV docking can be improved effectively.

The invention relates to a control method of a pressure-limiting glass evacuated solar water heater without a water tank. An electric heating pipe and a water temperature / level sensor are arranged in a heat collector. A water feeding valve is arranged on a water inlet pipe of the heat collector. A hot water faucet, a water flow sensor, a check valve, a relief valve, a water pressure switch, a safety valve, an expansion valve and an intake valve are sequentially arranged in the direction from the water outlet of a water outlet pipe of the heat collector to the heat collector. The water pressure switch is electrically connected with the water feeding valve and a controller. The water outlet pipe between the check valve and the water flow sensor is connected with the water inlet of the waterinlet pipe by a cold water pipe which is provided with a signal valve. The water flow sensor, the intake valve, the relief valve and the signal valve are all connected with the controller. The solar water heater adopts the method of using the water pressure switch on the water outlet pipe to detect the water pressure in the heat collector and to combine the signal valve on the cold water pipe to ensure the water heater to supply water normally, which is simple in structure, reasonable in design, safe, convenient, good in freeze-proof and shock-proof effects, high in intelligent control degreeand free from potential safety hazard.
