[0002] my country is a major aquaculture country in the world, and real-time water quality monitoring plays an important role in the development of the aquaculture industry. There are two main existing water quality monitoring modes: manual sampling and testing mode and the establishment of a fixed-point water quality monitoring system mode. In the manual sampling mode, staff collect water samples from various parts of the water area and bring them back to the laboratory for testing and analysis to achieve monitoring. The real-time performance is poor, and due to the irresistible factors of environmental changes and the influence of time during transportation, the properties of the water samples are likely to change, which ultimately leads to false detection of water quality and low monitoring accuracy. The establishment of a fixed-point water quality monitoring system mode generally divides the water area into multiple monitoring areas, and sets water quality sensors in each monitoring area. The water quality sensors collect water quality data of the corresponding monitoring area in real time and transmit it to the host computer to achieve real-time water quality monitoring.

However, since sewage or harsh environments contain various corrosive substances, such as acids, alkalis, oils, and corrosive and flammable gases, if they are in water for a long time, it is easy to cause serious corrosion to the shell of the electronic equipment. During the period from entering the water to the working position, they are subject to long-term corrosion and are difficult to use. Summary of the Invention

[0017] The present invention provides a combined corrosion-resistant protective device for underwater electronic equipment, which has the following beneficial effects:

[0018] 1. The combined corrosion-resistant protection device for underwater electronic equipment is driven by a first motor to rotate. The rotation of the first transmission shaft drives the first driving gear to rotate. The rotation of the first driving gear drives the outer ring gear to rotate. The rotation of the outer ring gear drives the turntable to rotate. When the turntable rotates, the turntable drives the turntable to rotate. The turntable drives the helical ring gear to rotate. When the helical ring gear rotates, it drives the two helical gears to rotate. When the helical gear rotates, it drives the support ring to rotate. When the support ring rotates, it drives the sealing baffle to rotate. When the two sealing baffles rotate, the two support shafts limit the support ring. When the two sealing baffles are deflected in the opposite direction, the two fixed blocks are pushed, so that the two fixed blocks push the arc push rod to move. When the arc push rod moves, it drives the piston plate to move and drives the sealing ring to move inside the piston cylinder. When the fixed block moves, it squeezes the buffer spring to form a buffer and improve stability. At the same time, when the piston plate slides inside the piston cylinder, the buffer flows from the multiple through holes to form a damping effect, enhance the buffering capacity, and improve stability and safety.

[0019] 2. The combined corrosion-resistant protective device for underwater electronic equipment drives the fixed sleeve to rotate at the same time when the rotating plate rotates, and the fixed sleeve drives the threaded sleeve to rotate. The threaded sleeve rotates to limit the threaded rod, so that the threaded rod descends. When the threaded rod descends, it drives the fixed plate and the mounting plate to descend, thereby driving the protective cover to descend. When the sealing baffle is opened, the protective cover is lowered for easy work. At the same time, the second motor is started to drive the second transmission shaft to rotate. The second transmission shaft drives the second driving gear to rotate, so that the second driving gear drives the driven gear to rotate, thereby causing the driven gear to drive the vertical shaft to rotate. The vertical shaft drives the rotating sleeve to rotate, so that the rotating sleeve drives the limiting plate to rotate when it rotates. The limiting plate drives the threaded rod to rotate. When the threaded rod rotates, the threaded sleeve limits the threaded rod, so that the threaded rod descends when it rotates, driving the support plate to rotate inside the fixed plate and driving the fixed plate to descend. When the fixed plate descends, it drives the mounting plate and the protective cover to descend, which is beneficial for the protective cover to extend out of the protective shell, making it convenient to work and protecting the equipment when it is not in working state to reduce corrosion.

[0020] 3. The combined corrosion-resistant protective device for underwater electronic equipment needs to fix the electronic equipment inside the protective cover before the device is put into water, and fix the protective cover to the mounting plate. The plug-in block is driven to be plugged into the mounting plate through the protective cover, and the threaded outer ring is rotated to make the threaded outer ring descend. When descending, the threaded outer ring pushes the positioning rod to move, so that the positioning rod moves toward the inside of the positioning block, thereby limiting the positioning block and thus limiting the plug-in block. Then the screw is rotated to make the screw drive the threaded ring to move. When the threaded ring moves, it drives the two arc plates to move. When the arc plate moves, it drives the cross bar and the locking rod to move, so that the locking rod limits the two positioning rods, thereby improving stability, which is beneficial to fix the protective cover and prevent the equipment from falling off.
