Description

Technical Field

[0001] The present invention relates to the technical field of distributed power generation, and in particular to an offshore power generation device integrating automatic light-seeking solar energy, wind energy and tidal energy. Background Art

[0002] With the development of society, the demand for electricity in various countries is constantly increasing. Traditional thermal power generation produces huge energy waste and environmental pollution, and consumes primary energy, which is non-renewable. Hydropower generation uses the potential energy of water to generate electricity, but it is limited by season, time and region and cannot meet the real-time needs of electricity users. Nuclear power has the characteristics of high efficiency and low resource consumption, but the biggest problem of nuclear power is safety and pollution to surrounding areas. Compared with traditional thermal power generation, hydropower generation and nuclear power, emerging clean energy has the characteristics of low energy consumption, cleanliness and pollution-free, such as solar energy, wind energy, tidal energy, etc. Since the 21st century, solar power generation technology and wind power generation technology have made great progress, but most solar power generation and wind power generation equipment are concentrated in open plateau areas. It is undeniable that open plateau areas are the gathering places of solar energy resources and wind energy resources, but the ocean is also a place where multiple resources such as solar energy, wind energy and tidal energy are gathered. The sunlight on the ocean is unobstructed and is far more abundant than that on land. In the same area, the wind on the sea is much stronger than that on land. The constantly surging sea water below the sea level has more abundant tidal energy, and the diurnal rise and fall of the sea water near the coast brings infinite tidal energy.

[0003] Solar energy, wind energy, and tidal energy are all recognized as new clean energy sources. The current solar power generation technology and wind power generation technology are far superior to tidal power generation technology. Tidal energy belongs to marine energy. In recent years, the development and research of marine energy has become a new research topic. Tidal power generation is similar to the principle of hydropower generation. There is a drop in sea water between high tide and low tide. The potential energy of sea water is used to drive the blades of the tidal generator to rotate, driving the tidal generator to rotate. Considering that solar power generation has low power generation efficiency at night and on cloudy days, and wind power generation has low power generation efficiency in seasons with low wind, these factors have led to the instability of solar power generation and wind power generation.

[0004] At present, the motion structure of the solar panel of the automatic light-seeking solar power generation technology is realized by the gear movement driven by the motor and the rotation axis movement driven by the motor. In Patent No. CN107834970A, the left and right rotation and the up and down movement are all realized by the motor-driven gear movement. The problem of the motor-driven gear movement is that it consumes a lot of electricity, the gear wears and the inspection and maintenance are difficult. In Patent No. CN109525028A, the automatic light-seeking is to control the angle of the solar panel through six telescopic rods fixed in the vertical direction. The problem is that the six telescopic rods fixed in the vertical direction can adjust the angle of the solar panel too small, and the solar panel is difficult and insensitive to move.

[0005] At present, the blades and supporting mechanism of vertical wind power generation technology are relatively fixed, which brings problems such as low wind energy utilization and serious wind damage to the blades. Patents CN109525028A and CN111197555A both adopt the method of relatively fixing the blades and supporting mechanism.

[0006] At present, the tidal power generation technology uses seawater thrust mainly by means of a fan-type blade structure to generate electricity. The tidal power generation of fan-type blades can only use the thrust of seawater in a single direction. When the tidal power generation of fan-type blades faces seawater that is not directly facing the fan-type blades, the rotation effect produced is very low, and the resulting power generation effect is not ideal.

[0047] The essential features of the present invention are:

[0048] The present invention adopts a new type of automatic light-seeking action device, using four telescopic rods as the supporting structure of the solar power generation panel, setting sliding balls in the directions of the four corners of the solar power generation panel as the connection points of the top of the telescopic rods, setting sliding balls on the upper surface of the hollow cylindrical base at the lower end of the solar power generation panel as the connection points of the bottom of the telescopic rods, and achieving the purpose of adjusting the angle of the solar power generation panel through the telescopic movement of the four telescopic rods. The advantages of this design structure are that it uses four telescopic rods as the action objects, with low investment and in line with the principles of economy and reliability; the connection point uses a sliding ball structure with low friction, low resistance and simple structure; the angle of the solar power generation panel can be flexibly and conveniently controlled through the mutual cooperation of the four telescopic rods, and the adjustable angle of the solar power generation panel is large.

[0049] The four blades of the present invention are rectangular in shape, and the four blades are 90 degrees apart from each other. The blades are connected to the support rods through the blade fixing module to ensure that the blades and the support rods can rotate relative to each other. When the blades in a certain direction are in the direction of movement of the wind, they are affected by the balancing force generated by the wind on the blades, and the blades in this direction are automatically adjusted to be perpendicular to the direction of movement of the wind, playing the main driving role of rotation. When the blades move to the direction of movement facing away from the wind, they are affected by the balancing force generated by the wind on the blades and the rotational force generated by the blades rotating around the second support column. The blades are automatically adjusted to a direction parallel to the wind direction, thereby automatically reducing the obstruction to the rotation, and will not hinder the blade module from rotating around the second support rod. When other blades rotate to the direction of movement of the wind, they will also automatically rotate according to the rotation law of the blades. This design structure in which the blades and the support rods can rotate relative to each other can maximize the effect of wind power generation. When severe weather such as typhoons occurs, the movable blades ensure that the blades can automatically adjust to the angle with the least damage from the typhoon in the wind, thereby reducing the damage to the blades from the typhoon.

[0050] Aiming at the problem that the tidal power generation of fan-type blades has a low rotation effect when facing seawater that is not directly facing the fan-type blades, the present invention adopts the vertical tidal power generation technology of double helical blades, which can produce an ideal rotation effect when facing seawater from all directions, thereby driving the tidal power generator shaft to rotate and produce a good power generation effect. The device can use seawater flowing in all directions to generate electricity, thereby improving the power generation efficiency of the device.

[0051] The present invention effectively combines automatic light-seeking solar power generation, wind power generation and tidal power generation. In different time periods, the main energy sources that can be used for power generation in the ocean vary greatly. Automatic light-seeking solar power generation is concentrated under conditions of sufficient sunlight during the day, while the amount of solar power generation is very small on cloudy days or at night; wind power generation is mainly concentrated in a certain time period of the year; tidal power generation is mainly concentrated in offshore and river areas, relying on the high tide phenomenon of seawater or river water twice a day in the morning and evening. In the device of the present invention, the automatic light-seeking solar power generation module is installed on the upper part of the vertical wind power generation module, the vertical wind power generation module is installed in the middle part, and the vertical tidal power generation module is installed in the lower part and set below the sea level. The three power generation modules cooperate with each other, and at least one power generation module plays a major role in any time period, ensuring the relative stability of the overall power generation of the device.

[0052] The beneficial effects of the invention are:

[0053] 1. The present invention effectively combines automatic light-seeking solar power generation, wind power generation and tidal power generation, greatly improving the efficiency of using marine resources for power generation and improving the stability of the overall power generation of the device. When the sunlight is sufficient during the day, the power generation of the automatic light-seeking solar power generation module is large; at night and on cloudy days, the power generation of the automatic light-seeking solar power generation module is very small. The wind power generation module generates large and concentrated power in a certain season or period. The tidal power generation module in the offshore and river areas relies on the phenomenon of high tide twice a day in the morning and evening of seawater or river water. When the tide is high, a large amount of seawater surges in, with great kinetic energy. At the same time, the water level rises, and the kinetic energy is converted into potential energy; when the tide is low, the seawater rushes back, the water level of the seawater drops, and the potential energy of the seawater is converted into kinetic energy. Therefore, the time period of tidal power generation in the offshore is concentrated. Tidal power generation in the open sea is affected by many factors, such as the tidal force of the sun, seabed currents and offshore wind, and the power generation is relatively stable. The three power generation modules cooperate with each other, and at any time period, at least one power generation module plays a major role to ensure the stability of the overall power generation of the device.

[0054] 2. The action principle of the solar panel in the automatic light-seeking solar power generation module: Take the contraction movement of a telescopic rod as an example to explain the principle of adjusting the angle of the solar panel. When the telescopic rod in a certain direction contracts or stretches, the sliding ball connected to the bottom end of the telescopic rod slides relative to the spherical groove wall on the upper surface of the hollow cylindrical base, and the sliding ball connected to the top end of the telescopic rod slides relative to the groove wall at the center of the connecting shaft of the solar panel module. At the same time, the sliding balls connected to the bottom ends of the other three telescopic rods slide relative to the spherical groove wall on the upper surface of the hollow cylindrical base, and the sliding balls connected to the top ends of the other three telescopic rods slide relative to the groove at the center of the connecting shaft of the solar panel module, thereby realizing the movement of the solar panel. In actual operation, the specific number of telescopic rods that perform telescopic movement at the same time depends on the actual sunlight conditions and the control signal output by the control module. The light signal is sensed by the photosensitive element at the top, and the signal is transmitted to the solar power generation controller. The solar power generation controller adjusts the extension degree of the four telescopic rods according to the light signal to ensure that the solar panel is vertically exposed to sunlight at any time, thereby improving the utilization rate of solar energy.

[0055] 3. The wind power generation module uses four vertical blades, and the blades and the supporting rods of the supporting body can rotate relative to each other. The wind power generation device can maintain the maximum wind energy utilization rate when facing wind energy from any direction. When the blades in a certain direction are in the direction of wind movement, they are affected by the balancing force of the wind on the blades, and the blades in this direction are automatically adjusted to be perpendicular to the direction of wind movement. When the blades are facing away from the direction of wind movement, they are affected by the rotational force and balancing force generated by the wind on the blades, and the blades are automatically adjusted to be parallel to the wind direction. When other blades rotate to the direction of wind movement, they will also automatically rotate according to the rotation law of the blades. Such a design can fully ensure the maximum utilization rate of wind energy.

[0056] 4. The wind speed sensor transmits the wind speed signal to the wind power generation control module in real time. The wind power generation control module will compare the detected wind speed with the set value. When the wind is too strong, the wind power generation control will send a signal to stop the wind turbine from generating electricity to prevent the shaft of the wind turbine from being damaged during high-speed rotation.

[0057] 5. The principle of tidal power generation is similar to that of wind power generation. Wind power generation is based on the wind force driving the movement of wind turbine blades, driving the shaft of the wind turbine to rotate. The principle of tidal power generation is to use the thrust of the flow of seawater to drive the blades to rotate, driving the first gear, and through the mutual transmission between the first gear, the second gear, the third gear and the bevel gear, it plays the role of a transmission, driving the shaft of the tidal power generator to rotate at high speed.

[0058] 6. The horizontal cross-section of the tidal power generation blade is composed of a semicircle and an arc tangent to the semicircle, and a double helix 180 degrees is formed between the top and bottom ends of the two blades. This design structure will cause the nearby seawater to form a vortex, maximizing the use of the thrust of the seawater and improving energy utilization.

[0059] 7. The protection of the tidal energy generator is to monitor the speed of the tidal energy generator in real time with the help of a speed sensor. The tidal energy power generation control module compares the monitored speed with the set maximum value. If the speed is too high, the tidal energy power generation control module sends a stop power generation signal to the tidal energy generator and automatically puts it into use according to the set stop work time to achieve automatic protection of the tidal energy generator.

[0060] 8. Install obstacle lighting on the top of the device to ensure the safety of aircraft and ship navigation at night and when visibility is low.

[0061] 9. The battery stores electricity to ensure the normal operation of the obstacle lighting, control module and solar power generation module telescopic pole equipment for a period of time. The installation of the inverter can output electrical energy to the outside. The battery, inverter and control device are all installed on a console above sea level, which is convenient for maintenance personnel to perform maintenance on time.

Specific implementation plan

[0078] The implementation of the present invention is further described below in conjunction with the accompanying drawings:

[0079] The offshore power generation device integrating automatic light-seeking solar energy, wind energy and tidal energy described in the present invention is as follows: Figure 1 As shown, it includes an automatic light-seeking solar power generation module 1, a vertical wind power generation module 2, a vertical tidal power generation module 3, a battery 4, an inverter 5, a control module 6, a console 7 and a wireless communication module 8;

[0080] like Figure 2 As shown, the automatic light-seeking solar power generation module 1 comprises an obstacle lighting lamp 1.1, a photosensitive element 1.2, a solar power generation panel module 1.4 and a telescopic rod part 1.5 which are arranged in sequence from top to bottom on the basis of a supporting mechanism 1.3;

[0081] The supporting mechanism 1.3 of the automatic light-seeking solar power generation module comprises a first supporting column 1.3.1, a stepped supporting column 1.3.2 and a hollow cylindrical base 1.3.3.

[0082] The bottom of the hollow cylindrical base 1.3.3 has an outer ring with a through hole, and the top has an upper cover with a round hole. Four small round holes are evenly distributed around the upper cover. Four spherical grooves are evenly distributed in four directions around the upper surface of the hollow cylindrical base 1.3.3. A sliding ball 1.3.3.1 is arranged in each spherical groove. The sliding ball 1.3.3.1 is limited in the spherical groove by the upper cover with a round hole of the hollow cylindrical base 1.3.3. The diameter of the circular hole in the groove is 1 / 2 to 4 / 5 of the diameter of the sliding ball, and the top of the sliding ball 1.3.3.1 is exposed to the outside through the circular hole on the upper cover of the hollow cylindrical base 1.3.3; a stepped support column 1.3.2 is fixed on the hollow cylindrical base 1.3.3, and a first support column 1.3.1 is installed on the stepped support column 1.3.2, and the three have the same axis; the stepped support column 1.3.2 is a three-level to five-level stepped cylindrical structure (five levels in this embodiment). The outer ring diameter of the through hole at the bottom of the hollow cylindrical base 1.3.3 is equal to the diameter of the console 7, and the lower surface of the hollow cylindrical base 1.3.3 is installed on the upper surface of the console 7.

[0083] The obstacle index lamp 1.1 is installed at the top of the first support column 1.3.1; the photosensitive element 1.1 is installed at the part of the first support column 1.3.1 below the obstacle lighting lamp 1.1 and above the solar power generation panel 1.4.1.

[0084] like Figure 3 As shown, the solar panel module 1.4 includes a solar panel 1.4.1, a connecting piece 1.4.2, a connecting shaft 1.4.3, a connecting shaft cap 1.4.4 and a solar connector 1.4.5; the solar connector 1.4.5 is installed on the lower end surface of the solar panel 1.4.1 and is close to the circular hole in the center of the solar panel 1.4.1; the solar panel 1.4.1 is square, and a group (two pieces) of parallel connecting pieces 1.4.2 (the four groups of connecting pieces have the same distance from the center) are installed at 2 / 3 to 3 / 4 of the position on the line connecting the center of the lower end surface to the four corners, and the connecting piece 1.4.2 is perpendicular to the lower end surface of the solar panel 1.4.1, and there is a circular hole at the bottom of the connecting piece 1.4.2, and the axis of the center of the circular hole is perpendicular to the line connecting the center of the solar panel 1.4.1 to the vertex of the corner.

[0085] The connecting shaft 1.4.3 passes horizontally through the circular holes of the two parallel connecting plates 1.4.2, and the two ends of the connecting shaft are fixed by the connecting shaft caps 1.4.4 respectively; the connecting shaft 1.4.3 consists of three parts, the upper semi-cylinder of the connecting shaft, the lower semi-cylinder of the connecting shaft (the two semi-cylinders are closed and installed as a whole), and the middle sliding ball 1.4.3.1; there is a spherical groove between the upper semi-cylinder and the lower semi-cylinder of the connecting shaft, and the center of the spherical groove is close to and higher than the lower surface of the lower semi-cylinder. The diameter of the spherical groove is smaller than the diameter of the connecting shaft, so that the central part of the lower surface of the lower semi-cylinder of the connecting shaft is hollowed out, and the diameter of the sliding ball 1.4.3.1 is 10 / 11 of the diameter of the spherical groove, and the sliding ball 1.4.3.1 is confined in the spherical groove between the upper semi-cylinder and the lower semi-cylinder of the connecting shaft, and the lower end of the sliding ball 1.4.3.1 is exposed to the outside through the hollowed-out part of the center of the lower surface of the lower semi-cylinder of the connecting shaft.

[0086] The telescopic rod 1.5 includes a first telescopic rod 1.5.1, a second telescopic rod 1.5.2, a third telescopic rod 1.5.3, and a fourth telescopic rod 1.5.4; the top of the telescopic rod is connected to the sliding ball 1.4.3.1 in the middle of the connecting shaft 1.4.3 at the bottom of the solar panel, and the bottom of the telescopic rod is connected to the sliding ball 1.3.3.1 in the spherical groove of the hollow cylindrical base 1.3.3 in the vertical direction. (The telescopic rods 1.5 are all electric hydraulic telescopic rods, and each telescopic rod has a motor device at the bottom)

[0087] The center of the sliding ball 1.4.3.1, the center of the sliding ball 1.3.3.1 and the axis of the telescopic rod 1.5 are on the same straight line; the four sliding balls 1.3.3.1 of the hollow cylindrical base 1.3.3 are evenly distributed in four directions and are in the same direction as the four corners of the solar panel 1.4.1, that is, they are in the same direction as the sliding balls 1.4.3.1 in the four corners of the solar panel 1.4.1, and the sliding balls 1.3.3.1 in the same direction are connected to the sliding balls 1.4.3.1 through a telescopic rod 1.5; when the four telescopic rods perform telescopic movement, the directions of the four sliding balls 1.3.3.1 of the hollow cylindrical base 1.3.3 are always consistent with the directions of the four corners of the solar panel 1.4.1, ensuring that the solar panel 1.4.1 does not rotate relative to each other.

[0088] Movement principle of the solar panel module: Take the contraction movement of a telescopic rod as an example to illustrate the principle of adjusting the angle of the solar panel 1.4. When the telescopic rod 1.5 in a certain direction contracts or stretches, the sliding ball 1.3.3.1 connected to the bottom end of the telescopic rod slides relative to the spherical groove wall on the upper surface of the hollow cylindrical base 1.3.3, and the sliding ball 1.4.3.1 connected to the top end of the telescopic rod 1.5 slides relative to the groove wall in the center of the connecting shaft 1.4.3 of the solar panel module. At the same time, the sliding balls 1.3.3.1 connected to the bottom ends of the other three telescopic rods 1.5 slide relative to the spherical groove wall on the upper surface of the hollow cylindrical base 1.3.3, and the sliding balls 1.4.3.1 connected to the top ends of the other three telescopic rods 1.5 slide relative to the groove in the center of the connecting shaft 1.4.3 of the solar panel module, thereby realizing the movement of the solar panel. In actual operation, the specific number of telescopic rods 1.5 that perform telescopic movement at the same time depends on the actual sunlight conditions and the control signal output by the control module 6.

[0089] The working principle of automatic light-seeking solar power generation: the photosensitive element 1.2 is a spherical resistor element, and its resistance value changes with the intensity of the incident light. When the incident light is enhanced, the resistivity increases and the resistance value decreases.

[0090] The photosensitive element 1.2 is connected to the second A / D converter 6.2.1 of the automatic light-seeking solar power generation control module 6.2, and the second A / D converter 6.2.1, the second single-chip microcomputer 6.2.2 and the second drive circuit 6.2.3 of the automatic light-seeking solar power generation control module 6.2 are connected in sequence, and the second drive circuit 6.2.3 is connected to the motor of the telescopic rod 1.5; the photosensitive element 1.2 transmits the detected light signal to the second single-chip microcomputer 6.2.2 through the second A / D converter 6.2.1, and the second single-chip microcomputer 6.2.2 transmits the action signal to the motor of the telescopic rod 1.5 through the second drive circuit 6.2.3, and the telescopic rod 1.5 adjusts the extension degree of the four telescopic rods 1.5 according to the action signal, thereby changing the angle of the solar power generation panel 1.4.1, so that the solar power generation panel 1.4.1 receives the most ideal lighting conditions.

[0091] like Figure 4 As shown, the battery 4, inverter 5, control module 6 and wireless communication module 8 are respectively mounted on the upper end surface of the console 7. The hollow cylindrical base 1.3.3 of the automatic light-seeking solar power generation module 1 is mounted on the upper end surface of the console 7, and the outer ring set at the bottom of the hollow cylindrical base 1.3.3 is fixed to the console 7 by four bolts. The hollow cylindrical base 1.3.3 of the automatic light-seeking solar power generation part 1 sets the battery 4, inverter 5, control module 6 and wireless communication module 8 in the hollow space inside the hollow cylindrical base 1.3.3.

[0092] The control console 7 is installed at the top of the second support column 2.1 in the vertical wind power generation module 2;

The first rolling bearing 2.3.1 is located on the upper part of the second rolling bearing 2.3.2 and is arranged in parallel. The inner walls of the first rolling bearing 2.3.1 and the second rolling bearing 2.3.2 are respectively connected to the second support column 2.1, and the outer walls of the two are respectively installed in the inner circular hole in the center of the installation body 2.3.4 (the installation body 2.3.4 is a square-like structure with four sides of the same arc concave curve, and the midpoint of the side curve is to the installation body 2. 3.4 The distance between the center points is 1 / 4 to 2 / 5 of the distance between the two adjacent end points.) The center of the installation body 2.3.4 has a circular hole, and the diameter of the circular hole is the same as the diameter of the outer wall of the first rolling bearing 2.3.1. The connection points of four support pillars 2.3.3 are evenly distributed on the outside of the installation body 2.3.4, and the difference between every two adjacent connection points is 90 degrees; the four support pillars 2.3.3 are respectively connected to the connection points on the outside of the installation body 2.3.4. The material of the installation body 2.3.4 and the support pillars 2.3.3 are both low alloy steel Q345. (The first support body 2.3 is connected to the second support pillar 2.1 through two rolling bearings in the middle, the purpose of which is to increase the contact area so that the second support pillar 2.1 can evenly bear the weight of the support body and the four blades. The two rolling bearings can effectively reduce the rotation resistance, which is conducive to the rotation of the rolling bearing around the center.)

[0096] like Figure 7As shown, the second support body 2.4 includes a first rolling bearing 2.4.1 and a second rolling bearing 2.4.2 at the center of the second support body 2.4, four support pillars 2.4.3, and a mounting body 2.4.4. The structure of the second support body 2.4 is exactly the same as that of the first support body 2.3. The first support body 2.3 is mounted on the upper part of the second support pillar 2.1, and the second support body 2.4 is mounted on the lower part of the second support pillar 2.1. The two together play the role of supporting the fan blade module 2.5.

[0097] The fan blade module 2.5 comprises a first fan blade 2.5.1, a second fan blade 2.5.2, a third fan blade 2.5.3 and a fourth fan blade 2.5.4. The back of each fan blade is provided with two fan blade fixing modules 2.6, which are respectively located at the upper half and the lower half of each fan blade.

[0098] like Figure 7 As shown, there are four first connecting rods 2.2, the top end of each first connecting rod 2.2 is fixed to the lower end surface of a supporting pillar 2.4.3 of the second supporting body 2.4, and the bottom end is vertically arranged on the upper end surface of the large disc 2.8.1, and is evenly distributed in four directions.

[0099] The wind speed sensor module 2.7 includes a wind speed sensor 2.7.1 and a wind speed sensor base 2.7.2; the wind speed sensor 2.7.1 is installed on the upper end surface of the wind speed sensor base 2.7.2; the wind speed sensor base 2.7.2 is a semi-cylindrical structure, the diameter of the semi-cylinder is equal to the width of the transverse support rod 2.9, and is installed on the transverse end surface of one side of the transverse support rod 2.9;

[0100] The wind turbine cover module 2.10 comprises a wind turbine cover 2.10.1, bolts 2.10.2 and nuts 2.10.3. The wind turbine cover module 2.10 is mounted on the lateral end surface of the lateral support rod 2.9 on the side where the wind turbine 2.8.4 is mounted.

[0101] like Figure 8As shown, the fan blade fixing module 2.6 includes a first fixing plate 2.6.1, a second fixing plate 2.6.2, bolts 2.6.3, nuts 2.6.4, and gaskets 2.6.5 of the fan blade; the first fixing plate 2.6.1 and the second fixing plate 2.6.2 of the fan blade fixing module 2.6 are parallel to each other and parallel to the upper end surface of the fan blade 2.5.1; each support pillar 2.3.3 includes two upper and lower rolling bearings at the end, namely a first rolling bearing 2.3.3.1 and a second rolling bearing 2.3.3.2; the fan blade fixing module The first fixing plate 2.6.1 and the second fixing plate 2.6.2 of the block 2.6 have a vertical circular hole; the bolt 2.6.3 of the fan blade fixing module 2.6 passes through the circular hole of the first fixing plate 2.6.1 of the fan blade, the gasket 2.6.5, the inner wall of the first rolling bearing 2.3.3.1 at the end of the supporting pillar 2.3.3 of the supporting body 2.3, the inner wall of the second rolling bearing 2.3.3.2 at the end of the supporting pillar 2.3.3, the gasket 2.6.5, the circular hole of the second fixing plate 2.6.2, and finally the nut 2.6.4 is screwed on to fix it.

[0102] like Fig. 9 As shown, the transmission module includes a large disc 2.8.1, a small disc 2.8.2, a crawler track 2.8.3, a wind turbine 2.8.4 and bolts 2.8.5; the transverse support rod 2.9 is horizontally installed on the second support column 2.1 at the bottom of the transmission module 2.8 and horizontally penetrates the second support column 2.1. The wind turbine 2.8.4 is installed on the transverse end surface of one side of the transverse support rod 2.9, and the wind speed sensor module 2.7 is installed on the transverse end surface of the other side; the bottom of the wind turbine 2.8.4 is fixed with four bolts 2.8.5 of the transmission module 2.8 A small disc 2.8.2 is installed on the rotating shaft at the top of the wind generator 2.8.4 on the lateral end surface of the lateral support rod 2.9; the large disc 2.8.1 and the small disc 2.8.2 rotate horizontally and synchronously through the track 2.8.3; the wind generator cover 2.10.1 is fixed to the lateral support rod 2.9 on one side of the wind generator 2.8.4 with bolts 2.10.2 and nuts 2.10.3, and the wind generator 2.8.4 is sleeved inside the wind generator cover 2.10.1 to prevent the wind generator 2.8.4 from being damaged by wind and rain.

[0103] The upper end face of the second support column 2.1 is installed at the center of the lower end face of the console 7. The second support column 2.1 is connected in sequence from top to bottom to the inner wall of the first rolling bearing 2.3.1 and the inner wall of the second rolling bearing 2.3.2 of the first support body 2.3, the inner wall of the first rolling bearing 2.4.1 and the inner wall of the second rolling bearing 2.4.2 of the second support body 2.4, the inner wall of the first rolling bearing 2.8.1.1 and the inner wall of the second rolling bearing 2.8.1.2 of the large disk 2.8.1 of the transmission module 2.8, and the transverse support rod 2.9. Finally, the lower end face of the second support column 2.1 is installed at the center of the upper end face of the third support column 3.5 of the vertical tidal energy power generation module 3.

[0104] Working principle of wind power generation: The four blades of wind power generation are rectangular, and the four blades are 90 degrees apart. The blades are fixed to the support rods 2.3.3 of the support body 2.3 through the blade fixing module 2.6 to ensure that the blades and the support rods 2.3.3 can rotate relative to each other. When the blades in a certain direction are in the direction of wind movement, affected by the balancing force generated by the wind on the blades, the blades in this direction automatically adjust to be perpendicular to the direction of wind movement, playing a major role in driving the rotation. When the blades move to the direction of movement facing away from the wind, affected by the balancing force generated by the wind on the blades and the rotational force generated by the blades rotating around the second support column, the blades automatically adjust to a direction parallel to the wind direction, thereby automatically reducing the obstruction to rotation, and will not hinder the blade module from rotating around the second support rod. When other blades rotate to the direction of wind movement, they will also automatically rotate according to the rotation law of the blades. This design structure in which the blades and the support rods can rotate relative to each other can maximize the effect of wind power generation. When the blades of the wind power generation device face wind from any direction, at least one of the four blades can play a major role in driving the wind, and the other blades will not hinder the wind, so that the four blades rotate around the second support column 2.1, thereby ensuring the maximum utilization of wind energy. The blades drive the large disc 2.8.1 connected to the first connecting rod 2.2 to rotate, and the large disc 2.8.1 drives the small disc 2.8.2 to rotate through the crawler 2.8.3. The connection between the large disc 2.8.1 and the small disc 2.8.2 through the crawler 2.8.3 plays the role of a transmission, accelerating the rotation of the shaft of the wind turbine 2.8.4 connected to the small disc 2.8.2.

[0105] like Fig.10 As shown, the vertical tidal power generation module 3 includes a first blade 3.1, a second blade 3.2, a first fixed disk module 3.3, a second fixed disk module 3.4, a third support column 3.5, a connecting cylinder 3.6, a gear transmission module 3.7, a tidal power generator module 3.8, and a cabin module 3.9 at the bottom of the device.

The diameter of the semicircle is 1 / 4 to 1 / 8 of the diameter of the arc tangent to it. The thickness of the blade is 10 to 30 cm, and the outer edge of the blade is smoothed to ensure that the blade can maximize the use of the tidal energy of seawater. A 180-degree spiral is present between the bottom and the top of the blade; the top of the first blade 3.1 and the second blade 3.2 are installed on the lower end surface of the fixed disk 3.3.1 of the first fixed disk module 3.3, and the bottom is installed on the upper end surface of the fixed disk 3.4.1 of the second fixed disk module 3.4. The first blade 3.1 and the second blade 3.2 are made of a rigid metal material with a certain hardness; the first blade 3.1 and the second blade 3.2 in the present invention are made of aluminum alloy, which will not deform during the rotation process, ensuring that the first fixed disk module 3.3 and the second fixed disk module 3.4 rotate coaxially and synchronously, and the aluminum alloy has the characteristics of resisting seawater corrosion. The first blade 3.1 and the second blade 3.2 are both double helical blade structures. The helical structure is the same as the blade shape in patent number CN 208010513 U.

[0107] like Fig.12As shown, the first fixed disk module 3.3 includes a fixed disk 3.3.1, a fixed arc rod 3.3.2, a bolt 3.3.3, a rolling bearing 3.3.4 and a connecting block 3.3.5. The second fixed disk module 3.4 includes a fixed disk 3.4.1, a fixed arc rod 3.4.2, a bolt 3.4.3, a rolling bearing 3.4.4 and a connecting block 3.4.5. (3.3 and 3.4 have the same structure and are mirror-imaged) The fixed arc rod 3.3.2 of the first fixed disk module 3.3 is installed on the upper end surface of the fixed disk 3.3.1 of the first fixed disk module 3.3, and the upper end surfaces of the first blade 3.1 and the second blade 3.2 are installed on the lower end surface of the fixed disk 3.3.1 of the first fixed disk module 3.3.

[0116] The basic principle of the tidal power generation part: the first blade 3.1 and the second blade 3.2 are double helical blades with a helicity of 180 degrees.

[0126] The software or protocols involved in the present invention are all well-known technologies, which are provided by the relevant devices, or are programmed by those skilled in the art according to the existing technologies.

[0127] The overall size of the present invention and the size of the components are determined according to the conditions of the actual use site. In this embodiment, the total height of the device is about 24 meters, the part above the sea level is about 15 meters, and the part below the sea level is about 9 meters. The height ratio of the three parts of the automatic light-seeking solar power generation module 1, the vertical wind power generation module 2, and the vertical tidal power generation module 3 is about 1:5:4, and the mass ratio of the three parts is 1:2:3; the solar power generation panel 1.4.1 is a square structure, and its side length is about 1 / 3 of the overall height of the device, so the area of ​​the solar power generation panel is about 35 square meters, the daily power generation is about 70 degrees, and the weight of the solar power generation module is about 400 kilograms; the vertical wind turbine uses 30 kilowatts, the height is about 10 meters, the weight is about 1000 kilograms, and the daily power generation is about 550 degrees; the vertical tidal power generator uses 30 kilowatts, the height is about 8 meters, the weight is about 1200 kilograms, and the daily power generation is about 400 degrees. In summary, the overall daily power generation of the present invention is about 1020 degrees.

[0128] In the automatic light-seeking solar power generation module 1, the first support column 1.3.1, the stepped support column 1.3.2, the hollow cylindrical base 1.3.3 and the control console 7 in the support mechanism 1.3 are all made of low-alloy steel Q345; the load-bearing pillars of the device are the second support column 2.1 and the third support column 3.5, both of which are made of solid cylindrical low-alloy steel Q345, and their diameters are 80 to 120 cm.

[0129] The purpose of the present invention is to maximize the use of marine resources to generate electricity based on the current power generation technology, and to improve the power generation structure of the three parts respectively, rather than simply piling up the three power generation methods. In the automatic light-seeking solar power generation module, the automatic light-seeking action device is improved, and four telescopic rods are used to support the solar power generation panel, and the connection points at the top and bottom of the telescopic rods adopt a sliding ball structure, which ensures that the solar power generation panel can flexibly adjust the angle of the solar power generation panel. In the vertical wind power generation module, the fixed structure of the fan blades is improved, and a fan blade fixing module is adopted in which the fan blades and the support rods can rotate relative to each other. During the wind power generation process, the fan blades automatically adjust the angle between the fan blades and the support rods according to the wind force, wind direction and the rotation force generated by the rotation of the whole device around the middle, avoiding the fan blades from hindering the rotation of the whole device around the middle, and when the fan blades are damaged by wind in bad weather, they can automatically adjust the angle between the fan blades and the support rods, so that the damage to the fan blades by the wind is greatly reduced. In the vertical tidal power generation module, the present invention improves the unidirectional seawater power generation device and adopts a multi-directional vertical blade structure. The blade structure is composed of a semicircle and an arc tangent to the semicircle, and the top and bottom of the two blades present a double helix of 180 degrees. This design structure can maximize the use of the thrust of seawater and produce the most ideal power generation. The three power generation technologies cooperate with each other and complement each other. The three power generation technologies have different power generation effects in different time periods. The present invention effectively combines the automatic light-seeking solar power generation module, the wind power generation module and the tidal power generation module. In different time periods, the main energy sources that can be used for power generation in the ocean vary greatly. The automatic light-seeking solar power generation is concentrated under the condition of sufficient light during the day, while the solar power generation is very small on cloudy days or at night; wind power generation is mainly concentrated in a certain time period of the year; tidal power generation is mainly concentrated in offshore and river areas, relying on the tide phenomenon of seawater or river water twice a day in the morning and evening. In the device of the present invention, the automatic light-seeking solar power generation module is installed on the upper part of the vertical wind power generation module, the vertical wind power generation module is installed in the middle part, and the vertical tidal power generation module is installed in the lower part and arranged below the sea level. At different times, the three power generation modules cooperate with each other to ensure that at least one power generation module plays a major role in any time period, thereby ensuring the relative stability of the overall power generation of the device.
