DETAILED DESCRIPTION

[0028] 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.

[0030] A water inlet assembly, which is arranged at the input end of the turbine frame 1 and is used to input water into the turbine frame 1;

[0031] The adjusting component 6 is arranged at one end of the blade 5. The adjusting component 6 includes a fixing block 603 fixedly connected to one end of the adjusting component 6. A thread groove 604 is provided at the top of the fixing block 603. The inner thread of the thread groove 604 is interlaced with an extension block 602.

[0032] The fixing component 7 is arranged at one end of the rotating shaft 2 , and is used to limit the rotation of the adjusting component 6 and fix the position of the blade 5 .

[0033] It should be noted that the turbine frame 1, shaft 2 and generator 3 are existing equipment. When in use, the shaft 2 is inserted and connected to the inner wall at the top of the turbine frame 1, so that the bottom end of the shaft 2 can penetrate into the interior of the turbine frame 1, and the top of the shaft 2 is connected to the generator 3; the blades 5 are set with reference to some technologies of the turbofan of an aircraft engine, that is, advanced blade 5 design and aerodynamic principles. On this basis, high-strength and corrosion-resistant materials are used to manufacture the turbine blades 5 to improve their strength and corrosion resistance; when water flows through the blades 5, the pressure and speed of the water flow cause the blades 5 to rotate, and drive the shaft 2 to rotate through the blades 5. The shaft 2 transmits this rotational motion from the blades 5 to the inside of the generator 3. The generator 3 receives the rotational force from the shaft 2 through the rotor inside it. The rotor rotates in the magnetic field to generate an induced current. When the rotor rotates, the change in the magnetic field causes a current to be generated in the stator coil of the generator 3. This current is rectified After the water flows and is adjusted, it is transported to the power grid or storage device; when the blade 5 is installed, the extension block 602 is rotated so that the extension block 602 moves inside the thread groove 604, thereby adjusting the thickness of the adjustment component 6, and finally the position of the adjustment component 6 is fixed by the fixing component 7, thereby adjusting the distance between the blade 5 and the water inlet; sensors such as pressure sensors, flow sensors and current sensors are installed on the magnetic power turbine generator, and various parameters of the device are monitored in real time by the sensors, and the operating state of the magnetic power turbine generator is adjusted by the obtained parameters to achieve the best operating effect; the set generator is consistent with the principle of the existing magnetic power generator, wherein the magnetic power system adopts high-performance permanent magnetic materials and special magnetic circuit design to enhance the magnetic field strength and stability and improve the power generation efficiency, and the power generation system adopts advanced winding technology and efficient rectifier inverter devices to ensure the stability and high quality of power output.

[0034] Specifically, the water inlet assembly includes a water inlet pipe 4 arranged at the input end of the turbine frame 1 .

[0035] It should be noted that the water inlet pipe 4 is fixedly connected to the input end of the turbine frame 1 , and water is input into the turbine frame 1 through the water inlet pipe 4 .

[0036] Specifically, the top of the extension block 602 is fixedly connected with a rotating block 601 for rotating the extension block 602, and the middle of the rotating block 601, the extension block 602 and the fixed block 603 are all provided with a first through hole, and the rotating shaft 2 is inserted and connected inside the first through hole.

[0037] It should be noted that the rotating block 601 is fixedly connected to the top of the extension block 602, and the extension block 602 is driven to rotate by the rotating block 601. The cross-sections of the first through holes opened on the rotating block 601, the extension block 602 and the fixed block 603 are consistent and are all compatible with the rotating shaft 2, so that the rotating block 601, the extension block 602 and the fixed block 603 can be sleeved on the bottom of the rotating shaft 2.

[0038] Specifically, the fixing assembly 7 includes a fixing ring 701 sleeved on the bottom of the rotating shaft 2, and a plurality of limiting rods 703 are fixedly connected to the bottom of the fixing ring 701 in a symmetrical manner.

The hole 704 and the third limiting hole 705 pass through the inner walls of the rotating block 601, the extension block 602 and the bottom end of the thread groove 604 in sequence, and limit the positions of the rotating block 601, the extension block 602 and the fixed block 603 with the thread groove 604 through the limiting rod 703 in a fixed position, so that the rotating block 601, the extension block 602 and the fixed block 603 cannot rotate, thereby avoiding the situation that the extension block 602 rotates inside the thread groove 604, thereby fixing the position between the extension block 602 and the fixed block 603.

[0040] Further, when installing the blade 5, the extension block 602 is first rotated according to the installation position of the blade 5, and the extension block 602 is moved inside the thread groove 604, so as to adjust the thickness of the adjustment component 6, thereby adjusting the installation position of the blade 5, and then the rotating block 601, the extension block 602 and the fixed block 603 are moved to the bottom of the rotating shaft 2, and the rotating block 601, the extension block 602 and the fixed block 603 are sleeved on the bottom of the rotating shaft 2 through the first through hole, and the limiting rod 703 passes through the rotating block 601, the extension block 602 and the fixed block 603 in sequence through the multiple limiting holes. 3, and limit the rotation of the rotating block 601, the extending block 602 and the fixed block 603 by limiting the rotation of the rod 703, move the rotating block 601 to fit with the bottom end of the fixing ring 701, and then move the receiving block 707 and the fixing nut 708 to the bottom of the rotating shaft 2, so that the receiving groove 706 on the top of the receiving block 707 can receive the bottom end of the limiting rod 703, and then make the fixing nut 708 threadedly sleeved on the bottom end of the rotating shaft 2, and clamp and fix the adjusting component 6 by squeezing the fixing nut 708 and the fixing ring 701, and fix the position of the blade 5 by fixing the adjusting component 6 in the fixed position.

[0041] Specifically, the rotating member 8 includes a connecting ring 802 fixedly connected to the bottom end of the storage block 707, a connecting groove 801 is opened at the top end of the fixing nut 708, the connecting ring 802 is inserted and connected inside the connecting groove 801, the bottom end of the connecting ring 802 is fixedly connected with a limiting ring 803, the inner wall of the bottom end of the connecting groove 801 is opened with a limiting groove 804, and the limiting ring 803 is inserted and connected inside the limiting groove 804.

[0042] It should be noted that the cross-sections of the provided connecting ring 802 and the opened connecting groove 801 are both circular rings, so that the connecting ring 802 can be inserted into the interior of the connecting groove 801 and the connecting ring 802 can be rotated inside the connecting groove 801; the opened limiting groove 804 is compatible with the provided limiting ring 803, and the cross-sections of the provided limiting groove 804 and the provided limiting ring 803 are both circular rings, so that the limiting ring 803 can be rotated inside the limiting groove 804, and the width of the provided limiting ring 803 is greater than the width of the connecting groove 801, so that the limiting ring 803 cannot pass through the connecting groove 801 and out of the limiting groove 804, thereby limiting the storage block 707 at the top of the fixing nut 708 by limiting the movement and allowing rotation of the limiting ring 803, and allowing the storage block 707 to rotate at the top of the fixing nut 708.
