DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In this embodiment, the control system adopts a PLC controller. Specifically, the PLC controller serves as the main control system. All input and output signals connected to the PLC controller are photoelectrically isolated inside the PLC controller, so that electrical photoelectric isolation is achieved between the external circuit and the internal circuit of the PLC controller. The CPU module of the PLC controller also adopts anti-electromagnetic interference shielding measures to ensure that the PLC controller is not interfered by external noise and electromagnetic radiation; the strong anti-interference ability of the PLC controller is used to improve the anti-interference ability of the overall constant potentiostat body 2. The PLC controller has a compact structure, small size, light weight, and high working reliability.

[0022] In the specific implementation process, the output end of the constant potential instrument body 2 is connected to the underground or underwater protected body, and the initial potential of the initial state of the detection end of the protected body is collected by the intelligent potential collector 3. Under normal circumstances, the ideal protection potential value of the protected body is -0.85V. The data of the initial potential and the normal difference of the potential are stored in the storage module. The intelligent potential collector 3 collects the potential of the detection point and transmits the value of the potential to the potential calculation module. The potential calculation module transmits the calculated potential to the potential comparison module, and compares the measured potential with the standard potential range. If the potentials are both within the standard potential range, the potential meets the standard. At this time, the control system issues a control instruction to control the constant potential instrument body 2 to operate according to the original preset potential. If the potential of the detection point is outside the standard potential range, the potential does not meet the standard. The difference between the potential and the normal potential is calculated by the potential adjustment amount calculation module, and the control system controls the constant potential instrument body 2 to automatically adjust the potential up or down to ensure that the cathodic protection potential in the entire project meets the standard and the protected body achieves the best protection effect.

A baffle 20 is fixedly sleeved on the outer surface of the rotating shaft 19, and a second gear 21 is fixedly sleeved on one end of the middle rotating shaft 19 located inside the vertical groove. Second electric push rods are fixedly installed on the inner walls of the left and right sides of the box body 1, and the output ends of the second electric push rods are fixedly connected to second racks 22, and the second racks 22 and the outer surface of the second gear 21 are movable. Engagement, specifically, the rain sensor 25 and the second electric push rod are both electrically fused with the control system, and the heat is dissipated from the electrical components in the box body 1 through the heat dissipation window 17. The dustproof net in the protective frame 18 reduces the dust from entering the box body 1 through the heat dissipation window 17. When the rain sensor 25 senses rainfall, it sends a signal to the control system, and the control system receives the signal and sends a signal to the second electric push rod. The second electric push rod drives the second rack 22 to move. When the second rack 22 moves, the second gear 21 rotates. The second gear 21 drives the rotating shaft 19. When multiple rotating shafts 19 rotate at the same time, the baffle 20 rotates, reducing the space between adjacent baffles 20, thereby reducing the possibility of rain entering the box body 1 through the heat dissipation window 17 and causing damage to the electrical components in the box body 1.

[0024] In this embodiment, sprockets 23 are fixedly sleeved on the outer surfaces of several rotating shafts 19, and chains 24 are wound around the several sprockets 23. Specifically, when the rotating shaft 19 rotates, the sprockets 23 thereon are driven to rotate, and under the action of the chain 24, multiple sprockets 23 rotate, thereby causing multiple rotating shafts 19 to rotate simultaneously.

[0025] During the specific implementation process, the heat dissipation window 17 is used to dissipate the heat of the electrical components in the box body 1, and the dustproof net in the protective frame 18 is used to reduce the dust from entering the box body 1 through the heat dissipation window 17. When the rain sensor 25 senses the rainfall, it sends a signal to the control system. The control system receives the signal and sends a signal to the second electric push rod. The second electric push rod drives the second rack 22 to move. When the second rack 22 moves, the second gear 21 rotates. The second gear 21 drives the rotating shaft 19 and the sprocket 23 thereon to rotate. Under the action of the chain 24, the other sprockets 23 rotate, so that the corresponding rotating shaft 19 rotates, so that the baffle 20 rotates, and the space between adjacent baffles 20 is reduced, thereby reducing the possibility of rain entering the box body 1 through the heat dissipation window 17 and causing damage to the electrical components in the box body 1.

The rotation of the rotating rod drives the mounting plate 6 to rotate the solar panel 7, and rotates the solar panel 7 to a vertical state. When the mounting plate 6 rotates to a position in contact with the stopper, the mounting plate 6 cannot continue to rotate due to the obstruction of the stopper. At this time, the first rack 12 continues to rise, and when the first rack 12 continues to move upward, it squeezes the tooth 10, causing the spring 9 to compress, so that the first rack 12 disengages from the tooth 10, thereby avoiding the influence of the tooth 10 that causes the first rack 12 to be unable to move upward.

[0027] In this embodiment, a first electric push rod 11 is fixedly installed on the top outer surface of the box body 1, and the output end of the first electric push rod 11 is fixedly connected to the first rack 12. The outer surface of the front vertical plate 5 is rotatably connected to the support shaft, and the outer surface of the support shaft is fixedly sleeved with a first gear 13. The first rack 12 is movably engaged with the outer surface of the first gear 13. Specifically, the rain sensor 25 and the first electric push rod 11 are both electrically connected to the control system. The first electric push rod 11 drives the first rack 12 to move, and when the first rack 12 is engaged with the first gear 13, it drives the first gear 13 to rotate.

[0028] In this embodiment, two support seats are fixedly connected to the top outer surface of the box body 1, and a connecting shaft is rotatably connected between the two support seats. The outer surface of the connecting shaft is fixedly sleeved with an L-shaped protective cover 14, and the outer surface of the L-shaped protective cover 14 is fixedly connected with a pull rope 16.

When the winding wheel 15 rotates, the two pull ropes 16 are reeled in, and the pull rope 16 drives the L-shaped protective cover 14 to pull up the L-shaped protective cover 14.

[0029] In this embodiment, a coil spring is wound around the outer surface of the connecting shaft, and the other end of the coil spring is fixedly connected to the top outer surface of the box body 1. Specifically, when the L-shaped protective cover 14 is pulled up, the connecting shaft is driven to rotate, causing the coil spring to deform. When the winding wheel 15 spits out the pull rope 16, the coil spring is reset, driving the connecting shaft to reset.

[0030] In this embodiment, two support frames are fixedly connected to the top outer surface of the box body 1, and support wheels are provided on the surfaces of the two support frames.

[0031] In the specific implementation process, the solar panel 7 absorbs sunlight, converts solar energy into electrical energy and stores it in the battery, and the battery provides the required electrical energy for the electrical components in the device. When the rain sensor 25 senses the rainfall, it sends a signal to the control system, and the control system receives the signal and sends a signal to the first electric push rod 11. The first electric push rod 11 drives the first rack 12 to move. When the first rack 12 moves, when the first rack 12 is engaged with the first gear 13, the first gear 13 rotates. The rotation of the first gear 13 drives the support shaft to rotate, and drives the winding wheel 15 thereon to rotate. When the winding wheel 15 rotates, the two pull ropes 16 are wound up, and the pull ropes 16 drive the L-shaped protective cover 14 to cover the L-shaped protective cover. The cover 14 is pulled up, and when the first rack 12 moves to engage with the teeth 10, it drives the disc 8 to rotate, and the disc 8 drives the rotating rod to rotate. The rotation of the rotating rod drives the mounting plate 6 to rotate the solar panel 7, and rotates the solar panel 7 to a vertical state. When the mounting plate 6 rotates to a position in contact with the stopper, the mounting plate 6 cannot continue to rotate due to the obstruction of the stopper. At this time, the first rack 12 continues to rise, and when the first rack 12 continues to move upward, it squeezes the teeth 10, so that the spring 9 is compressed, so that the first rack 12 is disengaged from the teeth 10, thereby avoiding the influence of the teeth 10 causing the first rack 12 to be unable to move upward, until the two L-shaped protective covers 14 are merged, thereby avoiding the damage to the solar panel 7 caused by raindrops falling in heavy rain.

[0032] Working principle: the output end of the constant potential instrument body 2 is connected to the underground or underwater protected body, and the initial potential of the initial state of the detection end of the protected body is collected through the intelligent potential collector 3. Under normal circumstances, the ideal protection potential value of the protected body is -0.85V. The data of the initial potential and the normal difference of the potential are stored in the storage module. The intelligent potential collector 3 collects the potential of the detection point and transmits the value of the potential to the potential calculation module. The potential calculation module transmits the calculated potential to the potential comparison module, and compares the measured potential with the standard potential range. If the potentials are both within the standard potential range, the potential meets the standard. At this time, the control system issues a control instruction to control the constant potential instrument body 2 to operate according to the original preset potential. If the potential of the detection point is outside the standard potential range, the potential does not meet the standard. The difference between the potential and the normal potential is calculated through the potential adjustment amount calculation module, and the control system controls the constant potential instrument body 2 to automatically adjust the potential up or down to ensure that the cathodic protection potential in the entire project meets the standard and the protected body achieves the best protection effect.

When the rain sensor 25 senses the rainfall, it sends a signal to the control system, and the control system receives the signal and sends a signal to the second electric push rod. The second electric push rod drives the second rack 22 to move. When the second rack 22 moves, the second gear 21 rotates. The second gear 21 drives the rotating shaft 19 and the sprocket 23 thereon to rotate. Under the action of the chain 24, the other sprockets 23 rotate, so that the corresponding rotating shaft 19 rotates, so that the baffle 20 rotates, and the space between adjacent baffles 20 is reduced, thereby reducing the possibility of rain entering the housing 1 through the heat dissipation window 17 and causing damage to the electrical components in the housing 1.

[0034] The solar panel 7 absorbs sunlight, converts solar energy into electrical energy and stores it in the battery, and the battery provides the required electrical energy for the electrical components in the device. When the rain sensor 25 senses the rainfall, it sends a signal to the control system, and the control system receives the signal and sends a signal to the first electric push rod 11. The first electric push rod 11 drives the first rack 12 to move. When the first rack 12 moves, when the first rack 12 is engaged with the first gear 13, the first gear 13 rotates. The rotation of the first gear 13 drives the support shaft to rotate, and drives the winding wheel 15 thereon to rotate. When the winding wheel 15 rotates, the two pull ropes 16 are wound up, and the pull ropes 16 drive the L-shaped protective cover 14 to pull the L-shaped protective cover 14. When the first rack 12 moves to engage with the tooth 10, it drives the disc 8 to rotate, and the disc 8 drives the rotating rod to rotate. The rotation of the rotating rod drives the mounting plate 6 to rotate the solar panel 7 and rotate the solar panel 7 to a vertical state. When the mounting plate 6 rotates to a position in contact with the stopper, the mounting plate 6 cannot continue to rotate due to the obstruction of the stopper. At this time, the first rack 12 continues to rise, and the first rack 12 squeezes the tooth 10 when it continues to move upward, so that the spring 9 is compressed, so that the first rack 12 disengages from the tooth 10, thereby avoiding the influence of the tooth 10 causing the first rack 12 to be unable to move upward, until the two L-shaped protective covers 14 are merged, thereby avoiding the damage to the solar panel 7 caused by raindrops falling in heavy rain.
