In this embodiment, the electric transport trolley 2031 moves up and down on the steel rope 3, and the steel rope 3 has an upper berthing point and a lower berthing point, and the upper berthing point contains an upper rubber expansion joint 101 that is sleeved on the upper end of the steel rope 3, and the upper end of the upper rubber expansion joint 101 is fixedly connected to the steel rope 3, and the lower end of the upper rubber expansion joint 101 cooperates with the steel rope 3 in a longitudinally movable manner along the steel rope 3.

The electric transport trolley 2031 is located on the section of the steel rope 3 between the upper anchor point and the lower anchor point, and a magnetic induction switch 2033 is provided at the bottom of the electric transport trolley 2031. The electric transport trolley 2031 is equipped with a temperature and salinity sensor and travels up and down on the steel rope 3 to observe the vertical profile of the water temperature and salinity. The observation depth is adjusted according to the water depth of the station. When the electric transport vehicle 2031 approaches the lower parking point, that is, when the magnetic induction switch 2033 senses the NiFeB magnetic ring 205, the power system of the electric transport vehicle 2031 realizes deceleration, braking, and the magnetic induction switch 2033 and the NiFeB magnetic ring 205 offset each other to achieve precise parking.

[0021] like Figure 1~Figure 3As shown, a support tower 102 extending outward is fixed on the upper surface of the buoy end 1. A power supply module, an energy storage battery and an information sending control module are arranged in the buoy end 1. The power supply module is connected to the energy storage battery, and the energy storage battery is connected to the information sending control module. The power supply module is used to convert external energy into electrical energy and charge the energy storage battery. The energy storage battery is used to provide driving power for the information sending control module. The information sending control module is used to receive the data transmitted by the temperature and salinity detection module 203 and send it to the host computer, and the information sending control module is used to control the charging module to charge the temperature and salinity detection module 203 through the energy storage battery, so that the temperature and salinity detection module 203 has enough energy to move up and down and perform temperature and salinity data detection.

[0022] like Figure 1~Figure 3 As shown specifically, the information sending control module contains an intelligent gateway, which is used to receive the temperature-salinity data sent by the temperature-salinity detection module 203, and the intelligent gateway is also used to control the charging module to start or stop operation. The electric transport vehicle 2031 contains a controller and a lithium battery, and the lithium battery is connected to the power system and controller of the electric transport vehicle 2031 to provide power for the power system and controller of the electric transport vehicle 2031. The temperature-salinity sensor is connected to the controller, and the temperature-salinity sensor transmits the temperature-salinity data to the controller. The controller sends the temperature-salinity data to the intelligent gateway by wireless communication. The controller and the intelligent gateway can realize wireless communication through Bluetooth and LORA. The specific method belongs to the prior art and will not be repeated here.

[0023] like Figure 1~Figure 3 As shown, the intelligent gateway is connected to a network unit and a positioning unit. The network unit is used to send the temperature and salinity data received by the intelligent gateway to the host computer through the network, and the positioning unit is used to send the current position information to the host computer. In this embodiment, the network unit is 4G and the positioning unit is Beidou. The network unit and the positioning unit are both fixed on the top of the support tower 102. The power supply module contains 4 solar panels, which are arranged around the middle of the support tower 102. The power supply module is connected to the energy storage battery, and the power supply module converts solar energy into electrical energy and stores it in the energy storage battery.

[0024] like Figures 1 to 4As shown, the charging module contains a driving circuit and a wireless charging transmitting coil 103 for driving the wireless charging transmitting coil 103 to form a continuous sinusoidal current oscillation state. The wireless charging transmitting coil 103 is fixed to the lower end of the upper rubber expansion joint 101, and the wireless charging transmitting coil 103 is connected to the energy storage battery through the driving circuit. A wireless charging receiving coil 2032 is fixed on the top of the electric carrier 2031, and the wireless charging receiving coil 2032 is electrically connected to the lithium battery for charging the lithium battery. The wireless charging transmitting coil 103, the controller, the lithium battery and the wireless charging receiving coil 2032 are all provided with a waterproof isolation membrane, and the waterproof isolation membrane is made of a material such as plastic that does not interfere with the magnetic field. In addition, in this embodiment, the electrical connections located underwater are all waterproofed, and the specific structure belongs to the prior art and will not be repeated here.

[0025] like Figures 1 to 3 As shown, the drive circuit adopts zero voltage switching (ZVS) / zero current switching (ZCS) technology, or soft switching technology. The efficiency of low-power soft switching power supply can be increased to 80%~85%. The information sending control module is driven by enabling. At the moment of power-on, the enable is directly added to the G poles of Q1 and Q2 through the current limiting resistors R3 and R2. Due to the slight difference between the two resistors and the slight difference in the junction capacitance of the two tubes, one of the tubes is turned on first. Assuming that Q1 is turned on first, VCC charges the capacitor C1 through L2. OUT1 and OUT2 are connected to the power transmission coil. The power transmission coil inductance and C1 form a parallel resonant circuit. The current of the power transmission coil rises according to the sine law. At this time, D1 is turned on to lower the G pole voltage of Q2, and Q2 is in the off state. The power transmission coil inductance and C1 form a parallel resonant circuit. The sine wave current follows the positive half-cycle curve. As time moves backward, when the sine wave resonates to the negative half-cycle. D1 is turned off. Q2 is turned on, D2 is turned on, Q1 is turned off, and the current of VCC flows through the inductor L1, C1, and the power transmission coil through the D and S of Q2 to form a loop to complete the negative half cycle of the sine wave current. As time goes on, the parallel resonant loop formed by the power transmission coil inductor and C1 will resonate along the positive half cycle curve and repeat the starting operation state, thus forming a continuous sine wave current oscillation state. A high-voltage and high-frequency sine wave voltage will be induced on the secondary of the transformer.

[0026] The ZVS high-frequency induction generator applies a high-frequency induction magnetic field to the power transmission coil, and the power receiving coil generates a 36V AC power supply. The 36V AC power supply is converted into 36V pulsating DC power through a bridge rectifier. The 36V pulsating DC power is output as 24V smooth DC power through the DC-DC power conversion module to charge the lithium battery.

[0027] In this embodiment, the electric energy generated by the solar panel is used to charge the lithium battery of the electric transport vehicle 2031 through the underwater wireless charging device. The minimum spacing between the power transmitting coil and the power receiving coil is 30mm and the maximum spacing is 70mm to achieve stable power transmission. Voltage 36V, current 20A, power 720W. The outer diameter of the power transmitting coil and the power receiving coil is 20cm, and the inner diameter is 9cm. The wire diameter is 1.5mm2. The double-layer induction coil is wrapped with polytetrafluoroethylene insulation layer, and the high-temperature vulcanized chloroprene rubber is die-cast and waterproof and pressure-resistant to 15Mpa.

[0028] When the temperature-salinity detection module 203 is located at the lower mooring point, the temperature-salinity detection module 203 is in a non-working state. When the temperature-salinity detection module 203 is located between the upper mooring point and the lower mooring point, the temperature-salinity detection module 203 is used to detect and store temperature-salinity data in the ocean water body. When the temperature-salinity detection module 203 is located at the upper mooring point, the temperature-salinity detection module 203 transmits data to the information sending control module, and at the same time, the temperature-salinity detection module 203 receives the electric energy transmitted by the energy storage battery. Specifically, the electric transport vehicle 2031 autonomously travels up and down along the limited track at a fixed time. During the driving process, the temperature-salinity sensor works to observe the vertical profile of the water body temperature and salinity. When floating to the upper mooring point, the collected data is transmitted to the intelligent gateway of the surface buoy through the wireless communication module. The intelligent gateway system turns on wireless charging at this time to charge the lithium battery on the underwater electric rail car. After charging is completed, the electric rail car descends to the lower mooring point to avoid wind and waves. Wait for the next collection time.

[0029] In this embodiment, the temperature and salt detection module 203 sends data to the information transmission control module by wireless transmission. Specifically, the peak power of wireless communication is 2W, and a flexible PFC antenna is used, which is easy to install and has its own heat dissipation patch, and can communicate continuously for a long time. The communication adopts a one-to-many, that is, one master and multiple slaves form to avoid interference in data transmission between modules. The communication frequency band adopts a communication method lower than 433Mhz, and the transmission is more reliable. The measured distance of underwater communication is greater than 15cm. The wireless data protocol frame includes the frame header and frame tail check bits, supports packet loss retransmission, and ensures the reliability of communication. The number of bytes in a single packet is controlled within 128 bytes to reduce the number of wireless air packet transmissions.

[0030] The observation depth of the ocean fixed-point observation buoy system of the present invention is adjusted according to the water depth of the station. The minimum speed on the cable track is 8m / s without derailment, jamming and other faults. The internal control needs to develop an automatic sensing system. When the electric rail vehicle approaches the upper and lower berthing points, it can achieve deceleration, braking, and precise parking. The underwater pressure resistance is 15Mpa and it can run without any faults for 180 hours. Underwater wireless charging. The electric energy generated by the solar panel charges the batteries of the electric rail carrier and the temperature and salinity sensor through the underwater wireless charging device. The minimum spacing between the power transmitting coil and the power receiving coil is 30mm and the maximum spacing is 70mm to achieve stable power transmission. Underwater wireless data transmission. When the electric rail carrier arrives at the upper berthing point, the data observed by the temperature and salinity sensor is quickly transmitted to the intelligent gateway at the buoy end 1, and then sent to the shore station server by the intelligent gateway to realize the timed and fixed-point temperature and salinity data detection.
