Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings: shown in Figures 1 and 2, the utility model includes a vertical water well box 1 with water in it, and a device that communicates with an external pressure gas source 2 is placed in the box body 1. Variable buoyancy box 3, the variable buoyancy box 3 is connected with a floating frame 5 fixing a group of generators 4; the rotor of the generator 4 is connected with a straight gear 7 through a group of bevel gears 6, and the spur gears 7 meshes with the vertical rack 8 arranged vertically along the inner wall of the box body 1 and can move up and down; the induced electromotive force output end of the generator 4 is connected to the current electric shock automatic converter 10 on the upper part of the box body 1 through the threading pipe interface 9 , and connect the external closed load circuit. the

The upper end of the box 1 of the utility model is provided with an upper-to-point positioning device 11, and the lower end is provided with a spring shock absorber 12; . The up-to-point positioning device 11 can be a limit switch, or other existing limit electric shock devices, etc.; the spring shock absorber includes a group of springs installed side by side at the bottom of the box, And the bottom of the floating frame is corresponding to the spring at the bottom of the casing, and a group of springs can also be set accordingly to form a spring shock absorber together; Rail guides, etc. the

The box body 1 shown in the figure is a long cube shape, and four rotors are installed in the circular floating frame 5, respectively facing the motors 4 of the respective side walls of the box body 1, and each side wall is respectively equipped with vertical rotors. Rack 8, four guide shoe devices 13 that are evenly distributed and play a vertical guiding role are installed on the peripheral wall of the floating frame 5. the

The floating frame 5 is placed on the bottom of the variable buoyancy box 3, and the top of the variable buoyancy box 3 is connected to the external pressure gas source 2 formed by a compressor through an inflation pipe 14; the variable buoyancy box 3 is also connected with an air switching valve 15 that can discharge the air in the variable buoyancy tank 3 step by step and is located at the top of the tank 1. the

The working process of the utility model is:

Due to the weight of the generator set itself, four groups of guide shoe devices 13 are used to perform vertical downward movement in the vertical water well box 1, and the power of rotation is transmitted to the bevel gear pair through four vertical racks 8 and spur gears 7, so that The rotor of the generator 4 is driven by the power of the bevel gear 6, and according to the principle of electromagnetic induction, the generator 4 will output an induced electromotive force through the string tube interface 9, and the closed load circuit can generate current. When the generator set drops to II When in position, the variable buoyancy tank 5 is increased in volume by the air tube 14, so that it can float the motor unit (according to the size of the generator unit, determine the volume of the buoyancy tank space), the generator unit starts to rise, and the rotor of the generator works Reverse rotation also generates induced electromotive force to generate electricity; when it rises to position I (gradually exhausts during the rising process), the generator 4 continues to move downward due to the blocking of the up-to-point positioning device 11, and reciprocates to generate electricity.

During the up and down movement of the generator 4, in order to overcome the change of the current direction due to the change of the rotor direction of the generator 4, four sets of current electric shock automatic converters 10 are installed above the box body 1. When the generator 4 reaches up to Point or down to the point, so that it automatically changes the contact position, so that the output current of each phase remains unchanged according to the original direction. the

During the sinking process of the generating set, according to the effect of the free fall under the acceleration, the sinking speed continues to increase. Although the water will have a buoyancy effect on the bottom surface of the generator 4, it still cannot slow down the sinking speed, so it must be inflated The variable-space buoyancy box 3 is constantly inflated by an air compressor to increase its buoyancy to reach a slow sinking speed. When the generator 4 sinks down to point II, the variable buoyancy tank 3 just expands to the position where buoyancy is generated, forcing the sinking potential energy to drop to zero, and at the same time, the current electric shock automatic converter 10 works, and the current electric shock automatic converter 10. Switch the contact to the floating power transmission position, and the generating set starts floating to generate electricity. the

When the generator 4 rises to a certain position, due to the pressure of the water on the upper surface of the variable buoyancy tank 3 (when approaching point I), the air switching valve 15 on the upper part of the tank 1 is opened to make the variable buoyancy tank 3 The air in the buoyancy box 3 is discharged gradually, and the kinetic energy of the air in the inflatable variable buoyancy box 3 will be reduced to zero, so that the generating set returns to the sinking position. At the power transmission position, the generating set began to sink to generate electricity. the

The power generation system can be widely used in civil electricity consumption in factories, enterprises, and residential quarters, and is an ideal green and environment-friendly power supply system outside the power grid. the
