Since the signal of the Beidou III short message transmission system 6 cannot penetrate the solar panel 9 for transmission, the Beidou III short message transmission system 6 needs to be placed above the solar panel 9 and fixed at the top of the upper hemisphere 42 by a nail-free adhesive. The cable passes through the solar panel 9 and is connected with the storage battery 7 and the tide level processing system 5, realizing the electrical connection of the Beidou III short message transmission system 6 with the storage battery 7 and the tide level processing system 5, so as to supply power to the Beidou III short message transmission system 6 and transmit information. The float ball 4 is provided with a position indicating lamp 12. The position indicating lamp 12 is provided with a plurality of position indicating lamps 12, which are evenly installed in the upper hemisphere 42 along the circumference of the float ball 4. The position indicating lamp 12 is powered by the storage battery 7 and is installed in the float ball 4 to facilitate connection with the storage battery 7. The position indicating lamp 12 is selected to be a red colored lamp, which has stronger penetration and can better play a position indicating role. The position indicating lamp 12 is connected with a light-dependent resistor, so that it is only turned on in a poor light environment. In a good light environment, the position indicating lamp 12 does not need to be turned on and is not easily noticed even if it is turned on. The position indicating lamp 12 is not turned on to save energy. The position indicating lamp 12 can remind surrounding ships to pay attention to the tide measuring equipment and reduce the probability of collision of ships with the tide measuring equipment.

[0038] With reference to Figure 1 and Figure 6 , the float ball 4 is provided with an anchor chain system 11. The anchor chain system 11 includes an anchor rope 111 and a fixed anchor 112. The anchor rope 111 is installed on the float ball 4 and is located five meters below the float ball 4, thereby reducing the probability of being scratched by a ship and the probability of being pulled by a ship. The fixed anchor 112 is installed on the end of the anchor rope 111 away from the float ball 4 and is fixed to the seabed. The fixed anchor 112 is fixed to the seabed to fix the float ball 4 and reduce the probability of displacement of the float ball 4 under the impact of water flow. The anchor chain system 11 is provided with two groups, which are respectively arranged on the two sides of the base 1. The two groups of anchor chain systems 11 can further improve the fixing effect and further reduce the probability of displacement of the float ball 4 under the impact of water flow.

[0039] With reference to Figure 1 and Figure 6The fixed anchor 112 includes an anchor rod 1121, anchor grabs 1122 and a fixing ring 1123. The anchor rope 111 is fixed to one end of the anchor rod 1121 in the length direction. The anchor grabs 1122 are evenly distributed in the circumferential direction of the anchor rod 1121. The anchor grabs 1122 are hinged to the end of the anchor rod 1121 away from the anchor rope 111. The fixing ring 1123 is slidably arranged on the anchor rod 1121. The anchor grabs 1122 rotate towards the direction close to or away from the anchor rod 1121. When the anchor grabs 1122 rotate close to the anchor rod 1121 to abut against the anchor rod 1121, the fixing ring 1123 slides to abut against the anchor grabs 1122 to limit the rotation of the anchor grabs 1122, thereby facilitating the storage and transportation of the fixed anchor 112. When the fixed anchor 112 is needed, the fixing ring 1123 is driven to slide away from the anchor grabs 1122, and the anchor grabs 1122 rotate away from the anchor rod 1121. At this time, the anchor grabs 1122 are arranged on the seabed to achieve the reinforcing effect. The anchor grabs 1122 and the anchor rod 1121 use bolts and nuts as the hinge shaft. The anchor 112 can be fixed by tightening the threads. The limiting block 20 is fixed on the anchor grabs 1122. When the anchor grabs 1122 rotate away from the anchor rod 1121 to form a 60-degree angle with the anchor rod 1121, the limiting block 20 abuts against the anchor rod 1121 to limit the rotation of the anchor grabs 1122. The anchor grabs 1122 are fixed by bolts and nuts. Under a large pulling force, the nuts are easy to loosen, causing the anchor grabs 1122 to continue to rotate. The anchor grabs 1122 will eventually lose the effect of being arranged on the seabed without limitation. The limiting block 20 limits the stroke of the anchor grabs 1122, thereby reducing the probability of excessive rotation of the anchor grabs 1122 and losing the grabbing force.

[0040] Referring to Figure 1 and Figure 7 The base 1 includes a mounting pipe 101 and support pipes 102. The mounting pipe 101 is circumferentially welded with a plurality of sleeves 21. In this embodiment, three sleeves 21 are provided. The support pipes 102 are provided in plurality. In this embodiment, three support pipes 102 are provided. The three support pipes 102 are respectively inserted into the three sleeves 21 and fixed on the sleeves 21 by bolts. The support pipes 102 support the base 1 to be placed on the seabed. The water pressure type water level meter 2 is inserted and mounted in the mounting pipe 101 and fixed in position by bolts. The mounting ring 10 for binding weights is welded and fixed on the mounting pipe 101. The mounting ring 10 is used to tie weights. The weight reduces the probability of the base 1 floating due to buoyancy and the probability of the base 1 being deviated due to water flow impact.
