It can be understood that, in the navigation mark terminal with the four-color full-color LED lamp device in this embodiment, the electric energy sources are the light-following solar power generation module 200, the wind power generation module 700 and the storage battery; the wind power generation module 700 is in transmission connection with a generator in the turnover device 500 through a transmission assembly 600, drives the generator to generate electricity, and provides electric energy for the navigation mark lamp; the turning device 500 may drive the wind power generation module 700 to turn, and adjust the wind power generation module 700 to be in a vertical state or a horizontal state according to the wind speed and through a control system.
Through the arrangement, the four-color LED navigation mark lamp 800 is provided with four-color LED lamps, RGBW four-color LED lamp beads are arranged in the four-color LED navigation mark lamp, the light color and the flashing frequency can be automatically adjusted and set according to practical conditions before use, and the four-color LED navigation mark lamp is used for navigation marks of different lamp types, so that the number of spare parts of the lamp is reduced, the utilization rate of the lamp is improved, and the storage pressure of equipment is relieved.
It can be appreciated that, because the offshore wind energy is intermittent and the wind speed is high and low, the horizontal axis wind power generation device has higher efficiency when the wind speed is higher; when the wind speed is small, the efficiency of the vertical axis wind power generation device is high.
In other words, when the wind speed is greater than the threshold value V Critical of When the horizontal axis wind power generation device is used, the efficiency is higher than that of the vertical axis wind power generation device; when the wind speed is less than the critical value V Critical of When the vertical axis wind power generation device is used, the efficiency is higher than that of the horizontal axis wind power generation device.
In order to enable the wind power generation module 700 to fully utilize wind power and have higher power generation efficiency, in the present embodiment, the wind power generation module 700 includes a horizontal axis wind power generation device 710, a transmission shaft 720, and a vertical axis wind power generation device 730; the horizontal axis wind turbine generator 710 and the vertical axis wind turbine generator 730 are both mounted on the transmission shaft 720; the transmission assembly 600 is arranged below the vertical axis wind power generation device 730, the transmission assembly 600 is mounted on the upper end face of the turning device 500, and the lower end of the transmission shaft 720 is in transmission connection with a generator arranged inside the turning device 500 through the transmission assembly 600.
Wherein when the wind speed is greater than the critical value V Critical of When the turning device 500 is used, the transmission shaft 720 is in a horizontal state, the blades 712 of the horizontal-axis wind power generation device 710 are opened, and the second blades 734 of the vertical-axis wind power generation device 730 are retracted; when the wind speed is less than the critical value V Critical of When the turning device 500 is turned over, the drive shaft 720 is in a vertical state, the blades 712 of the horizontal-axis wind turbine 710 are retracted, and the second blades 734 of the vertical-axis wind turbine 730 are opened.
Thereby eliminating the negative influence caused by the intermittent wind power at sea and fully utilizing the wind power. When the horizontal axis wind turbine 710 is in operation, the second blade 734 of the vertical axis wind turbine 730 is retracted, so that the second blade 734 is prevented from affecting the operation efficiency of the horizontal axis wind turbine 710; vice versa, this further improves the efficiency of wind energy utilization.
The switching between the operation of the horizontal axis wind turbine 710 and the operation of the vertical axis wind turbine 730 is also requiredThe wind power maintenance time is considered to ensure that the power generation efficiency gain after switching can cover the electric energy consumed by the switching of the working modes. In other words, if the wind speed is smaller than V Critical of Becomes greater than V Critical of (or vice versa) but for a short time it changes back to less than V Critical of It is not necessary to switch the operation mode.
It will be appreciated that V as described above Critical of May be determined from prior experiments or by simulation or expert experience. However, the applicant found the above V previously identified in a certain amount of experiments and practical practice Critical of The values will vary from practice, and in practice, the V Critical of The value may also vary with the objective conditions, such as differences between the actual operating environment and the test environment of the wind power module 700, which may result in V Critical of There may be a deviation in the values.
In order to solve the above-described problem, in the present embodiment, the operating wind speed of the horizontal axis wind turbine generator 710 is higher than V by a sufficient margin Critical of The value, i.e. the ambient wind speed exceeds the first wind speed threshold V b In this case, the horizontal axis wind turbine 710 is operated. Obviously V b >V Critical of . The operating wind speed of the vertical axis wind turbine 730 is lower than V with sufficient margin Critical of The value, i.e. the ambient wind speed is below the second wind speed threshold V s In this case, the vertical axis wind turbine 730 is operated. Obviously V s <V Critical of . The ambient wind speed V exceeds the second wind speed threshold V s But does not reach the first wind speed threshold V b When, i.e. V s ≤V<V b The operation mode of the wind power generation module 700 is temporarily not switched.
In other words, the operating wind speed of the vertical axis wind turbine 730 is V<V s The working wind speed of the horizontal axis wind power generation device 710 is V.gtoreq.V b . The initial first wind speed threshold V b A second wind speed threshold V s Determined empirically by an expert.
Further, in order to improve the accuracy of the threshold value, the present embodiment dynamically adjusts the first wind speed threshold value V b A second wind speed threshold V s Negative effects caused by the change of working conditions are eliminated. Specifically, a large range [ V s ，V b ) Average divided into several small ranges V 0 ，V 1 )、[V 1 ，V 2 )、……、[V i ，V i+1 )、……、[V n-1 ，V n ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein V is 0 =V s ，V n =V b And obviously (V) b -V s )/n=V i+1 -V i ，i=1,2,……,n。
If it isI=1, 2, … …, n, and the power generation efficiency of the vertical axis wind turbine generator 730 is higher than that of the horizontal axis wind turbine generator 710, the operating wind speed of the vertical axis wind turbine generator 730 is adjusted to V<V i+1 I.e. V b Keep unchanged, V s Is adjusted to V i+1 And, with a redetermined large range V i+1 ，V b ) Continuing the adjustment on the basis; if it isI=1, 2, … …, n, and the power generation efficiency of the vertical axis wind power generation device 730 is lower than that of the horizontal axis wind power generation device 710, the working wind speed of the horizontal axis wind power generation device 710 is adjusted to be V not less than V i I.e. V s Keep unchanged, V b Is adjusted to V i And, with a redetermined large range V s ，V i ) The above adjustment is continued on the basis.
By the above arrangement, a temporary large range V of the wind speed corresponding to the operation mode adjustment of the wind power generation module 700 is given s ，V b ) For the situation that the wind speed value is out of the large range, adopting a corresponding wind power generation mode can not only furthest improve the wind power generation efficiency, but also relatively eliminate the direct adoption of V Critical of Errors in the values. At the same time, dynamically adjust the first wind speed threshold V b A second wind speed threshold V s Has self-updating and self-adjusting functions, and is used for a first wind speed threshold V b AndSecond wind speed threshold V s Is more accurate.
