[0032] The left and right sides of the generator shell 100 are fixedly connected with two second guide cylinders 108 that are symmetrical in front and back, and each of the second guide cylinders 108 is occasionally provided with a guide cavity 133. The lower end surface of the generator shell 100 is fixedly connected with four solenoid valves 116, and the solenoid valves 116 are fixedly connected with a water pipe 130 extending into the guide cavity 133.

[0035] The fixing frame 117 is provided with a plurality of limiting holes 138 equidistant from top to bottom, and the hydraulic rod 137 can be coaxially aligned with each limiting hole 138, so that the bidirectional hydraulic pump 136 can drive the hydraulic rod 137 to be inserted into the limiting hole 138 to limit the generator housing 100;

[0036] The bottom plate 110 is fixedly connected with four connecting plates 111, which are fixed by ground nails 112 passing through the connecting plates 111 and nailed into the seabed, and the upper end surface of each connecting plate 111 is fixedly connected with a limiting cylinder 113, and a fixing rod 139 is slidably connected in the limiting cylinder 113, and the upper end surface of the fixing rod 139 is fixedly connected with the lower end surface of the generator housing 100, so as to ensure the stability of the generator housing 100;

[0037] A buoyancy block 115 fixedly connected to the lower end surface of the generator housing 100 is disposed in the middle of the connecting plate 111. The generator housing 100 is provided with four water outlets 128 connecting the water storage chamber 114 and each of the solenoid valves 116.

Each of the second guide tubes 108 is provided with a drainage hole 140 connecting the guide chamber 133 and the outside.

[0038] A fixing plate 107 is fixedly connected to the lower side of each second guide tube 108, and two connecting rods 129 are fixedly connected between the fixing plate 107 and the lower end surface of the generator shell 100. The connecting rods 129 are located at the front and rear sides of the water pipe 130, so as to ensure the stability of the second guide tube 108;

[0039] The second guide tube 108 is fixedly connected to a second waterproof shell 109 that seals and wraps the second generator 131, the upper end surface of the sealing plate 103 is fixedly connected to a first waterproof shell 104 that seals and wraps the first generator 120, and a transmission module 105 fixedly connected to the generator shell 100 is provided in the groove 102, thereby preventing water from entering the motor, and collecting and storing electric energy through the transmission module 105 and then transporting it to the shore for use.

[0040] See also Figure 1-Figure 11, this implementation includes the following steps:

[0041] S1: After the device passes through the connecting plate 111 through the ground nail 112, it is fixed on the seabed near the coast. The water level detector 106 monitors the change of the water level. Before the tide rises, the water level is the lowest. When the tide rises, the buoyancy block 115 drives the generator housing 100 to move up with the rise of the water level. After the water level rises a short distance, when the hydraulic rod 137 is aligned with the appropriate limit hole 138, the two-way hydraulic pump 136 is automatically started. The two-way hydraulic pump 136 drives the hydraulic rod 137 to be inserted into the limit hole 138 to limit the generator housing 100 and prevent the generator housing 100 from continuing to move up;

[0042] S2: As the water level continues to rise, when the water level exceeds the upper end of the generator housing 100, the water flows into the groove 102. When the water level rises to a point where the water pressure is greater than the magnetic force between the magnetic plate 126 and the sealing plate 103, the magnetic plate 126 moves downward, and the water flows from the water inlet 124 to the first guide tube 119, and then passes into the water storage chamber 114. When flowing through the first guide tube 119, the water flow drives the first spiral plate 122 to rotate, and the first spiral plate 122 drives the first motor shaft 121 to rotate. When the first motor shaft 121 rotates, the first generator 120 generates electricity, and the generated electrical energy is stored in the transmission module 105. After the water storage chamber 114 is filled with water, the spring 127 drives the magnetic plate 126 to re-engage with the sealing plate 103, so that electricity can be generated during the rising tide.

[0043] S3: When the tide is low, since the generator housing 100 is fixed only after the water level rises a short distance during high tide, the water level can be lower than the lower end surface of the generator housing 100 after the tide is low. When the water level detector 106 detects that the water level is lower than the lower end surface of the generator housing 100, the solenoid valve 116 is automatically opened, and the water in the water storage chamber 114 flows from the water outlet 128 through the solenoid valve 116, flows from the water pipe 130 into the diversion chamber 133, and flows out from the drainage hole 140. When flowing through the diversion chamber 133, the water flow drives the second spiral plate 134 to rotate, and the second spiral plate 134 drives the second motor shaft 132 to rotate. The rotation of the second motor shaft 132 causes the second generator 131 to generate electricity, and the generated electrical energy is stored in the transmission module 105, so that electricity can be generated when the tide is low;

[0044] S4: After the water flows out of the water storage chamber 114, the two-way hydraulic pump 136 drives the hydraulic rod 137 to retract from the limiting hole 138, and the movable frame 118 moves downward. The generator shell 100 floats on the water surface through the buoyancy block 115. The fixed rod 139 and the limiting cylinder 113 improve the stability of the generator shell 100 when floating, so that the two-way hydraulic pump 136 can be driven to be inserted into the appropriate limiting hole 138 according to the lowest water level at low tide in all seasons, so as to avoid being affected by different lowest water levels in different seasons.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
