The application discloses a ship lift bearing ship chamber on-line monitoring method and monitoring system, including the following contents: data monitoring, data acquisition, state evaluation and fault analysis; the health state of the equipment of the ship lift is evaluated according to the collected data; if the evaluation result is abnormal, a prewarning or alarm signal is sent according to the abnormal degree; when the alarm is monitored, the collected data is compared with the data in the data storage module, the alarm information is diagnosed and analyzed to generate the equipment fault maintenance decision; the application monitors the structure capacity and operation posture of the bearing ship chamber, and realizes real-time control of the structure performance index and equipment operation state of the bearing ship chamber, so that the bearing ship chamber is monitored; when the health state of the bearing ship chamber is in an abnormal state, the bearing ship chamber is adjusted and maintained in time; when the alarm signal is received, the monitoring data is compared with the data in the data storage module, the fault diagnosis is quickly obtained, and the maintenance decision is given.

The utility model relates to ship lift locking beam mounting equipment technical field, specifically disclose a locking beam positioning device for ship lift, right silk screw rod left end rotatably connected to the left side wall of box, and the right end is connected to the left end of reverse silk screw rod through the shaft coupling, the reverse silk screw rod right end passes through the right side wall of box and is connected to the output shaft of motor, the mounting block is screwed on the right silk screw rod, and the piston rod of lifting oil cylinder is connected to the locking plate vertically downward, a plurality of locking holes are equipped on the locking plate for connecting to the bearing plate of ship lift locking beam, the utility model sets up the right silk screw rod and reverse silk screw rod in the box, and the right silk screw rod and reverse silk screw rod are driven to rotate using motor, drive the locking plate transverse movement, adjust the horizontal position, start lifting oil cylinder and drive the locking plate to lift, adjust vertical height, adjust the position alignment of locking plate and bearing plate and carry out the butt joint, do not need to hoist equipment to move the bearing plate and carry out the butt joint, reduce the resource waste, improve the precision of butt joint.

The application discloses a ship lift anti-out-of-control operation device and a use method thereof. The ship lift anti-out-of-control operation device comprises a first shaft body rotatably arranged on a ship cabin, a second shaft body fixedly arranged on the ship cabin and a poking assembly arranged on the ship cabin. The first shaft body is in transmission connection with a transmission shaft of a driving system. A forward ratchet wheel and a reverse ratchet wheel are coaxially arranged on the first shaft body. A forward pawl and a reverse pawl are coaxially rotatably connected to the second shaft body. During operation of the poking assembly to a first state, the forward pawl is inserted into the forward ratchet wheel after rotation, the poking assembly pokes the reverse pawl and makes the reverse pawl exit the reverse ratchet wheel. During operation of the poking assembly to a second state, the reverse pawl is inserted into the reverse ratchet wheel after rotation, the poking assembly pokes the forward pawl and makes the forward pawl exit the forward ratchet wheel. The application can prevent the ship cabin from out-of-control up-and-down movement when the ship cabin loses driving force and the braking system fails, so as to avoid serious safety accidents such as ship cabin collision with the top or falling.

The application discloses a water level early warning method and system for a ship lift of a hydropower station, and the method comprises the following steps: collecting measured data of initial water levels, flow amplitude, flow speed, water level amplitude measured values within 20 minutes and water level overrun duration measured values under historical working conditions, verified working conditions and newly added working conditions; pre-processing variables; inputting the pre-processed variables into a multivariate nonlinear regression model in the following form, fitting and respectively; outputting the fitted and, and triggering early warning to guide gate control when the and exceeds 0.5 meters or exceeds a preset threshold. Through variable pre-processing, optimization and differential model structure design, the model can adapt to different generator tripping, load shedding working conditions and newly added working conditions, and the generalization ability is significantly better than that of an existing linear model with a fixed structure.

This utility model relates to the field of water conservancy engineering technology, specifically to a water conservancy hub structure, including an upstream reservoir and a downstream river channel. The upstream reservoir and the downstream river channel are connected by an intermediate channel, which includes a first tributary channel and a second tributary channel. The upstream of the first tributary channel and the upstream of the second tributary channel are connected to form a diversion point. The downstream of the first tributary channel flows into the downstream river channel. A ship lift is located at the confluence between the first tributary channel and the downstream river channel. A water-retaining overflow dam is located downstream of the second tributary channel. This utility model designs the intermediate channel as two tributary channels to divert water flow, with the upstream of the two tributary channels connected to form a diversion point. Water can flow into the two tributary channels separately. When passing through the diversion point, the flow velocity and impact force are reduced by the second tributary channel and the water-retaining overflow dam, greatly reducing the impact of the water flow on the ship lift and ensuring the normal operation of the ship lift and the normal navigation of the waterway.
