The recoverable underwater steel structure monitoring equipment has the beneficial effects that: can replace divers to observe under water. After the operation is completed, the monitoring equipment can be recycled to realize recycling. The application of the monitoring equipment can reduce the operation risk and the operation cost.
When the jacket centering device is used, two monitoring devices are arranged on the outer surface of the cylinder below the guide insertion tip and the secondary sealing ring on the upper portion of each insertion withdrawing of the jacket along the mutually vertical direction and are used for monitoring the centering installation process of the jacket. Two or three monitoring devices are uniformly arranged on the cylindrical surface near the grout overflow port of the jacket and used for monitoring whether grout overflow occurs in the grouting process so as to judge whether the grouting process is finished.
The monitoring equipment is adsorbed at the working position through the electric permanent magnetic chuck, the electric permanent magnetic chuck is electrified and magnetized on the land, and the monitoring equipment is adsorbed on the jacket to be inserted and withdrawn. After magnetizing and adsorbing, the power supply is cut off, and the electric permanent magnetic chuck can keep the magnetic attraction. And after the jacket and the steel pipe pile foundation are aligned, electrifying and demagnetizing the electric permanent magnetic chuck of the monitoring and aligning process equipment, and then recovering.

In the invention, the electric permanent magnet sucker can realize magnetization within 1-2 seconds after being electrified, can realize the magnetism keeping function after being powered off, and can realize demagnetization within 1-2 seconds after being powered on for a demagnetization signal of the electric permanent magnet sucker. Thus, the monitoring equipment can be installed at the designated position of the jacket by electrifying and magnetizing the electro-permanent magnetic chuck on land. After the monitoring equipment is installed, the electric permanent magnetic chuck can be powered off, and the monitoring equipment is still reliably adsorbed on the jacket after power failure. The monitoring equipment enters the sea surface along with the jacket, and after the monitoring work of centering installation is finished, the monitoring equipment which is observed to be centered and installed is recovered; and after the grouting monitoring work is finished, recovering the monitoring equipment for observing overflowed slurry. The electric permanent magnetic chuck can be designed according to the weight of the monitoring equipment, the ocean operation depth and the borne ocean disturbed flow, so that the adsorption force of the electric permanent magnetic chuck is determined. The electric permanent magnetic chuck needs to be designed in a sealing mode in the design process, and the situation that high-pressure seawater permeates into the electric permanent magnetic chuck to damage the performance of the electric permanent magnetic chuck is avoided.

The interior of the organic glass cover 10 can be dry air or dry inert gas, and the observation of the camera cannot be adversely affected by the dry enclosed gas. The organic glass cover 10 has good light transmittance and does not obstruct the camera 8 from monitoring the operation process. The organic glass cover 10 has a low density and a high strength, can play a role of protecting monitoring equipment, and can provide buoyancy required by floating upward by using a closed space. The buoyancy of the monitoring device when floating is determined by the volume of water drained by the monitoring device. The volume of the organic glass cover 10 can be designed, so that when the device is recovered, the buoyancy of the monitoring device is larger than the gravity of the monitoring device, equal to the gravity of the monitoring device or smaller than the gravity of the monitoring device, namely, the buoyancy of the monitoring device when the monitoring device floats upwards is designed by designing the volume of the organic glass cover 10.
The mounting bracket and the camera tightly hoop a reliable fixed camera.
The mounting rack 4 and the camera hoop 7 are made of materials which are not easy to corrode, and the included angle between the mounting rack 4 and the camera hoop 7 can be adjusted before the installation of the monitoring equipment according to the actual requirements of monitoring during engineering operation so as to determine the optimal observation angle. After the angle is adjusted, the protection and sealing are carried out by the organic glass cover 10. In addition, a motor can be arranged at the connecting position between the mounting frame 4 and the camera head clamping ring 7, a cable of the motor is led out through the cable sealing cover 5, and the angle between the mounting frame 4 and the camera head clamping ring 7 is automatically controlled, so that the organic glass cover 10 is not required to be detached, mounted and sealed when the angle is adjusted every time. After the camera 8 is installed in the camera tightening ring 7, the set screw 9 is reliably fixed.
The system can reliably recover the monitoring equipment and monitor the operation process.
The overwater control console and the monitoring console are connected through the electric permanent magnetic chuck cable 2 and the camera cable 6, underwater monitoring equipment is operated, and demagnetizing recovery and picture monitoring of the monitoring equipment are achieved. The lifting ring 3 is used for connecting a lifting rope, and when the designed buoyancy is smaller than the gravity, a certain lifting tension can be provided through the lifting rope; when the monitoring equipment floats to the water surface, the equipment is recovered through the lifting rope.
Function extension of the monitoring device
In order to better realize engineering operation, more functions can be integrated on the monitoring equipment:

integrating a temperature sensor on the monitoring equipment, and monitoring the temperature of the seawater while operating;
a pressure sensor is integrated on the monitoring equipment, so that the seawater pressure can be more reliably monitored during operation;
an acceleration sensor is integrated on the monitoring equipment, and the floating acceleration of the monitoring equipment is monitored when the monitoring equipment is recovered.
The invention monitors the centering installation process and the grouting process of the jacket, can operate in deep sea, can realize recycling and has the following characteristics:

The monitoring equipment is protected through the organic glass cover, and buoyancy is provided when the monitoring equipment floats upwards. And the organic glass cover has good light transmittance, and does not influence the monitoring of the camera on the operation process.
More sensors can be integrated by expanding functions, so that the monitoring process is more intelligent, and more physical parameters can be obtained.
The invention relates to a novel magnetic sucker for switching on and off magnetic force by electric pulse for an electric permanent magnetic sucker. The sucker is very safe and reliable in the process of sucking a workpiece to be processed. After the workpiece is magnetically held, the suction cup maintains the magnetic attraction force indefinitely. The time required for switching on and off is less than 1 second, the electric pulse energy consumption is very little, the sucker can not generate thermal deformation, the electric permanent magnetic sucker has no sliding parts similar to the magnetic group of the common permanent magnetic sucker, and the electric permanent magnetic sucker has stable and firm structure and high precision. The magnetic force is turned on and off by electric pulse, and the automatic control can be conveniently carried out. The electric control permanent magnetic chuck can be widely used for various surface grinding machines and electric processing machines to hold workpieces. The electric permanent magnetic chuck does not need electric energy in the working process, only depends on permanent magnetic suction to hold the workpiece, and avoids the danger that the workpiece falls off due to the loss of magnetic force caused by sudden power failure and offline damage of an electromagnetic system. Because the electric permanent magnetic chuck only uses electric energy within 1-2 seconds of the magnetizing and demagnetizing processes, no energy is used in the work to generate safe, strong and efficient force, thereby being economical and environment-friendly.
