Description

Technical Field

[0001] The invention relates to the technical field of power generation equipment, in particular to a power station for complementary photovoltaic power generation and tidal power generation on a sea surface composite buoyancy material. Background Art

[0002] With the development of society, people's demand for electricity is increasing. Due to the disadvantages of thermal power generation such as environmental pollution, wind power generation and solar power generation are increasingly being used. At present, for tidal power generation applications such as the ocean, a water storage dam is generally built on the seashore. When the tide comes and the water level is high, the dam will retain the water. When the tide ebbs, the retained water is released to impulse the impeller of the hydroelectric generator, and then the generator generates electricity. The above-mentioned method of using tidal energy to generate electricity has the disadvantages of high investment cost and will damage the ecological environment of the coast near the coast, so it has great limitations. Based on the above, it is particularly necessary to provide a power station with low investment and will not damage the coastal ecological environment. Summary of the invention

[0003] In order to overcome the disadvantages of equipment utilizing tidal power generation, which, due to technical limitations, has high costs, will damage the coastal ecological environment, and is inflexible to use, the present invention provides a device that can be conveniently deployed at any location in the ocean for use, which can not only effectively utilize the energy of the rise and fall of the ocean water level including tidal energy during operation, but can also effectively combine photovoltaic power generation to supply power to electrical loads, thereby effectively achieving a power station that is flexible to use, low in cost, will not damage the coastal ecological environment, and is environmentally friendly and energy-saving, and that complements photovoltaic power generation and tidal power generation on sea surface composite buoyancy materials.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] The power station for photovoltaic power generation and tidal power generation complementing each other on the composite buoyancy material on the sea surface includes multiple groups of solar panel assemblies, and is characterized by also having a floating box, a hydropower generation mechanism, and a gas collecting cover; the floating box is a hollow box, and a counterweight block is provided at the lower end of the floating box; the multiple groups of solar panel assemblies are respectively installed at the upper end of the floating box; the hydropower generation mechanism includes an impeller shaft, a hydropower drive device, and a generator; there are multiple hydropower drive devices, each of which includes a spring, a cylinder, a piston, and a jet pipe, and a shaped limit plate is installed at the lower end of the cylinder, and the spring is located at At the inner upper end of the cylinder, the piston is located at the inner lower end of the cylinder, the outer diameter of the piston is larger than the inner diameter of the hollow part of the limit plate, and the lower end of the jet pipe is vertically installed on the upper end of the cylinder; there are multiple fixing holes on the floating box; the multiple cylinders of the hydropower generation mechanism are respectively installed in the multiple fixing holes; there are multiple impellers at intervals on the impeller shaft, each impeller has multiple impeller blades, bearing seats are installed on both sides of the floating box, the two ends of the impeller shaft are respectively sleeved in the inner rings of the bearing seats on both sides, and the rotating shaft of the generator and one side of the impeller shaft are installed together; the gas gathering hood is installed on the upper end of the bearing seat.

[0006] Furthermore, there is an impeller on the other side of the impeller shaft, and the number of the water energy driven devices is one less than the impeller on the impeller shaft.

[0007] Furthermore, the gas collecting hood is a conical shell with an open structure at the lower end, an exhaust pipe is installed at the upper end of the conical shell, the front end of the exhaust pipe is aligned with the blades of the impeller on the other side of the impeller shaft, and the two are spaced apart.

[0008] Furthermore, the jet pipes of the plurality of water energy driving devices are respectively directed upward to the lower end of an impeller blade located at the lower part of the front end of the plurality of impellers of the impeller shaft and are spaced apart.

[0009] Furthermore, after the piston is installed in the cylinder, the piston is located at the lower dead point in the cylinder.

[0010] The beneficial effect of the present invention is that when the present invention is used, several sets of the present invention can be installed on the ocean not far from the coastline for parallel power generation, so that the purpose of flexible installation can be achieved. Since no water storage dam is built on the coast, the environment around the coast will not be affected. In the present invention, not only electricity is generated through solar panels, but also electricity can be generated through hydropower generation mechanisms. When the ocean is tidal, the sea level will have large fluctuations (there will still be ups and downs at the upper end of the sea level without tides). The fluctuation of the sea level pushes the piston upward and downward, so that the upper air in the cylinder of the hydropower drive device will be compressed and directly impact the blades to rotate, and then the impeller shaft rotates to drive the generator to generate electricity. The present invention is special in that it can also effectively utilize the airflows sprayed out by multiple nozzles to impact the impeller, thereby effectively utilizing energy and improving the power generation efficiency of the generator. Based on the above, the present invention has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

The front and rear parts of the upper end of the box 2; the hydropower generation mechanism includes an impeller shaft 3, a hydropower drive device 4, and a generator 5; there are multiple hydropower drive devices 4, each of which includes a spring 41, a hollow cylindrical cylinder 42, a piston 43, and a jet pipe 44. The upper end of the cylinder 42 is a sealed structure and the lower end is an open structure. A hollow annular limit plate 421 is threadedly installed at the lower end of the cylinder 42. The spring 41 is located at the inner upper end of the cylinder 42, and the piston 43 is located at the inner lower end of the cylinder 42. The outer diameter of the piston 43 is larger than that of the cylinder 42. The inner diameter of the hollow part of the limit plate 421, the upper end of the cylinder 42 has an opening, and the lower end of the jet pipe 44 is vertically welded to the outside of the upper end of the opening; the middle part of the floating box 2 has a plurality of fixing holes 22 that pass through from top to bottom at a certain distance from left to right, and the fixing holes 22 and the inside of the floating box 2 are in an isolated state; the multiple cylinders 42 of the hydropower generation mechanism are respectively installed in the multiple fixing holes 22 through screws and nuts; the impeller shaft 3 is welded with a plurality of impellers 31 at a certain equidistant interval, each impeller 31 has a plurality of impeller blades, and the floating box 2 is provided with a plurality of impeller blades. A bearing seat 7 is installed on the upper part of the left and right ends of the moving box 2 through a screw nut. The left and right ends of the impeller shaft 3 are respectively sleeved in the inner rings of the two bearing seats 7. The right end of the impeller shaft 3 is located on the right outer side of the right end bearing seat 7. The generator 5 is installed on the rightmost end of the upper middle part of the floating box 2 through a screw nut. The rotating shaft of the generator 5 and the right end flange of the impeller shaft 3 are connected together through a screw nut; the gas collecting hood 6 is installed on the upper end of the bearing seat 7, and the electric energy output by the solar panel 1 and the generator 5 is connected to the shore through a wire.

[0014] Figure 1As shown in the figure, the impeller shaft is located outside the left end bearing seat and there is an impeller 31. The number of the water-powered driving equipment 4 is one less than the impeller 31 of the wheel shaft. The gas collecting cover 6 includes a conical shell 61 with an open structure at the lower end. The left and right sides of the lower end of the conical shell 61 are installed on the upper ends of the two bearing seats 7 through screws and nuts. An exhaust pipe 62 connected to the shell is welded to the upper end of the conical shell 61. The middle part of the exhaust pipe 62 is welded to the left outer end of the shell 61. The front end of the exhaust pipe 62 is downwardly aligned with the rear side of a blade at the upper end of the impeller 31 outside the left end bearing seat, and the two are spaced a certain distance apart. The jet pipes 44 of multiple water-powered driving equipment are respectively located at the lower end of an impeller blade at the lower part of the front end of multiple impellers 31 of the impeller shaft 3 and are spaced a certain distance apart. After the piston 43 is installed in the cylinder 42, the piston 43 is located at the lower end dead point in the cylinder 42.

[0015] Figure 1 As shown in , in actual application, several sets of the present invention can be installed in the ocean not far from the coastline for parallel power generation, so as to achieve the purpose of flexible installation. Since no water storage dam is built on the coast, the environment around the coast will not be affected. In the present invention, the solar panel 1 is illuminated to generate electricity. During the power generation of the hydroelectric power generation mechanism, the sea level of the ocean will have large fluctuations during the tide (there will still be ups and downs at the upper end of the sea level without tide). When the water at the sea level fluctuates upward, it will push the piston 43 in the cylinder 42 of the hydroelectric drive device 4 to overcome the elastic force of the spring 41 and move upward. Then, the piston 43 compresses the air at the upper end of the cylinder 42 and ejects it from the upper part of the jet pipe 44 at high speed to act on the multiple impellers 31 of the impeller shaft 3 to rotate. Then, the rotation of the impeller shaft 3 drives the rotating shaft of the generator 5 to rotate, and the generator generates electrical energy. In the present invention, the high-velocity air ejected from the multiple cylinders 42 acts on the impeller, gathers at the inner upper end of the air hood 6, and is discharged at high speed through the exhaust pipe 62 (the airflow ejected at this moment has greater energy because it is the convergence of the airflow ejected from multiple cylinders), acts on the impeller 31 at the leftmost end of the impeller shaft to rotate, and improves the power generation capacity of the generator, which effectively utilizes energy and improves the power generation efficiency of the generator. The cylinder 42 and piston of the present invention have a larger diameter (3 meters in diameter) and can effectively utilize the energy of the fluctuation of sea level water. When the water at the sea level fluctuates downward, the spring 41 will push the piston 43 downward, preparing for the next upward fluctuation of the sea level water to drive the impeller shaft to rotate.
