Description

Technical Field

[0001] The present invention relates to the technical field of wind power monitoring devices, and in particular to a device for secure data transmission in the wind power field. Background Art

[0002] Wind power generation refers to the conversion of wind's kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source that has been used by people since ancient times, mainly through windmills to pump water. People are interested in how to use wind to generate electricity. Wind is one of the pollution-free energy sources, and it is inexhaustible. For coastal islands, grassland pastoral areas, mountainous areas and plateaus that lack water, fuel and transportation, it is very suitable to use wind power generation in accordance with local conditions, and there is great potential for it.

[0003] Wind power is an important area for the development of renewable energy, an important force in promoting wind power technology progress and industrial upgrading, and an important measure to promote energy structure adjustment. my country is rich in wind energy resources. Accelerating the construction of wind power projects is of great significance for promoting the control of atmospheric haze, adjusting the energy structure and transforming the economic development model.

[0004] ZigBee is a low-power LAN protocol based on the IEEE802.15.4 standard. According to international standards, ZigBee technology is a short-range, low-power wireless communication technology. Its characteristics are short distance, low complexity, self-organization, low power consumption, and low data rate. It is mainly suitable for the fields of automatic control and remote control and can be embedded in various devices. In short, ZigBee is a cheap, low-power, short-range, stable wireless networking communication technology.

[0005] Existing wind monitoring devices can only monitor wind in one direction. For example, a device for secure data transmission in the wind power field disclosed in the prior art (CN 212535939U) includes a wind vane and a spiral fixing block. A top cover is provided below the wind vane, and threaded fixing members are installed on the left and right sides above the top cover. A screw is installed inside the threaded fixing member. A strip groove is provided below the spring. A first rotating shaft is installed on the left side of the clamping strip. A fan blade is installed on the right side of the monitoring component. A first motor is provided below the bearing. The spiral fixing block is located inside the second outer shell. A spiral rod is installed inside the first outer shell. The first gear is meshed and connected below the second gear. A second motor is installed on the right side of the second rotating shaft. The wind monitoring device can adjust the height of the wind vane and rotate the wind vane.

[0006] Although the above-mentioned method of monitoring wind force by using a wind vane can adjust the height and rotation of the wind vane, and can conveniently monitor the wind direction in different environments, in actual application, due to the installation location of the wind turbine at a high altitude, the traditional wind vane has a simple structure and cannot accurately monitor the wind force according to the wind direction; more importantly, the traditional wind monitoring device cannot stably and safely transmit the monitoring data from the high altitude to the handheld device of the relevant operator on the ground, and has the disadvantage of poor data transmission effect.

[0048] Specifically, a connecting gear space 214 is provided on the main surface of the mobile mainboard 203 at a position corresponding to the connecting gear 206, and the tooth body of the connecting gear 206 can be transmission-connected with the outer mobile gear 210 through the connecting gear space 214;

[0049] The wind fan shaft seat 302 in the wind monitoring assembly 3 is fixedly installed on the inner cavity bottom surface of the protective cover 213 and the position corresponding to the wind fan shaft 303. The wind fan shaft 303 is sealed and screwed into the inner cavity of the protective cover 213 from the wind fan shaft position 301 and then rotatably connected to the wind fan shaft seat 302. A tachometer seat 306 is fixedly installed at the upper end of the wind fan shaft seat 302 and the position corresponding to the tachometer 307. The main body of the tachometer 307 is fixedly installed on the bottom surface of the tachometer seat 306. A sensor position 308 is opened at the position of the wind fan shaft 303 at the axis corresponding to the rotation sensor 305. The rotation sensor 305 is installed and connected in the sensor position 308.

[0050] Specifically, the bottom end of the transfer base 501 in the information transfer assembly 5 is evenly fixed with an array support pin 502, and the information transfer assembly 5 is fixedly connected to the operating ground through the array support pin 502. The ZigBee data receiving module 503 and the outgoing communication module 504 are both installed on the top surface of the transfer base 501. The top surface of the transfer base 501 is also sealed with a round cover 505;

[0051] The present invention is connected to the column at the lower end of the wind turbine blade by fixing the array connecting piece 103 in the fixed base component 1;

[0052] The external handheld smart device establishes a connection with the outgoing communication module 504, the outgoing communication module 504 establishes a connection with the ZigBee data receiving module 503, the ZigBee data receiving module 503 establishes a connection with the ZigBee data forwarding module 212, and the ZigBee data forwarding module 212 is electrically connected to the control mainboard 211. At this time, the external handheld smart device can send a wind monitoring instruction to the control mainboard 211;

[0053] According to different wind directions, the control mainboard 211 starts the moving motor 209, and the moving motor 209 drives the moving gear 210 to rotate. The moving gear 210 cooperates with the connecting gear 206 for transmission, and the connecting gear 206 can form a cooperative transmission with the main fixed gear 101;

[0054] Since the moving gear 210 and the connecting gear 206 are both fixedly connected to the moving main board 203, the moving main board 203 and the components connected and fixed to the moving main board 203 can be driven to move in a circular manner along the main fixed gear 101, and the moving main board 203 can be moved to the direction to be monitored according to different wind directions;

[0055] While the connecting gear 206 cooperates with the main fixed gear 101 to drive the moving mainboard 203 to move, since the upper and lower ends of the moving mainboard 203 are both rotatably provided with inner guide wheels 208, the inner guide wheels 208 at the upper and lower ends are both rollingly connected in the reversing slide rails 201 at the upper and lower ends of the main fixed gear 101; at this time, the inner guide wheels 208 at the upper and lower ends and the connecting gear 206 jointly form a triangular structure support for the main fixed gear 101, which can ensure the stable movement of the moving mainboard 203;

[0056] After the mobile mainboard 203 moves to the direction to be monitored, the wind blades 304 in the wind monitoring assembly 3 begin to rotate freely after being aligned with the wind direction. Since the wind blades 304 are plugged and fixed in the freely rotating wind fan shaft 303, the tachometer 307 can monitor the rotation speed of the rotation sensor 305 installed in the middle of the wind fan shaft 303 and calculate the rotation speed of the wind fan shaft 303. At this time, the rotation speed of the wind fan shaft 303 monitored is the wind force value generated by the rotation of the corresponding wind blades 304.

[0057] The tachometer 307 feeds back the monitored wind force value to the control mainboard 211, and the control mainboard 211 transmits the data of the wind force value to the ZigBee data forwarding module 212. The ZigBee data forwarding module 212 transmits the data in real time to the ZigBee data receiving module 503 installed on the ground. The ZigBee data receiving module 503 transmits the data to the outbound communication module 504. By connecting the external handheld smart device with the outbound communication module 504, the real-time data of wind monitoring can be obtained. Compared with the transmission method of directly connecting the handheld device to the wind monitoring device, it is less affected by the external environment and the data transmission process is more stable and reliable.

[0058] Embodiment 2:

[0059] On the basis of the first embodiment, the present invention realizes the example of linked heat dissipation. Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the cooling fan 404 in the linkage cooling assembly 4 is vertically rotated in the inner cavity of the protective cover 213, and the cooling fan 404 is drivingly connected to the inner shaft end of the wind fan shaft 303, and waterproof cooling holes 407 are provided on the left and right sides of the cavity of the protective cover 213 corresponding to the cooling fan 404;

[0060] Specifically, the rotating bevel gear 401 in the linkage heat dissipation assembly 4 is plugged and fixed on the inner shaft end of the wind fan shaft 303, and a heat dissipation shaft seat 403 is fixedly connected to the outer main surface of the movable mainboard 203 at a position corresponding to the rotating bevel gear 401, and a heat dissipation shaft 409 is rotatably connected in the heat dissipation shaft seat 403, and a conversion bevel gear 402 is plugged and fixed on the bottom shaft end of the heat dissipation shaft 409 at a position corresponding to the rotating bevel gear 401, and the conversion bevel gear 402 is meshedly connected with the rotating bevel gear 401, and the heat dissipation fan 404 is plugged and fixed at the middle position of the shaft of the heat dissipation shaft 409;

[0061] Specifically, heat dissipation cavities 405 are provided at positions corresponding to the left and right cavity walls of the protective cover 213 and the heat dissipation fan 404, and a heat dissipation cavity 406 is installed and connected in each group of heat dissipation cavities 405, and an array of waterproof heat dissipation holes 407 is evenly provided on the outer main surface of the corresponding heat dissipation cavity 406, and a dust removal core 408 is installed and connected in each group of heat dissipation cavity 406 to absorb dust;

[0062] Specifically, the outer air outlet of the waterproof heat dissipation hole 407 is located at the lower side of the waterproof heat dissipation hole 407, and the inner air inlet is located at the inner side of the waterproof heat dissipation hole 407. Through the L-shaped ventilation design, it can play a role in rainproof and waterproof;

[0063] When the wind drives the wind blades 304 to rotate, the wind blades 304 coaxially drive the rotation of the rotating bevel gear 401 in the linkage heat dissipation assembly 4 through the wind fan shaft 303, and the rotating bevel gear 401 and the conversion bevel gear 402 form a matching transmission to drive the rotation of the conversion bevel gear 402, and the conversion bevel gear 402 coaxially drives the rotation of the heat dissipation fan 404 through the heat dissipation shaft 409. The wind force generated by the rotation of the heat dissipation fan 404 can discharge the heat generated during the operation of the components in the protective cover 213 to the external environment through the waterproof heat dissipation holes 407 opened on the outer main surfaces of the heat dissipation cavity 406 on both sides of the protective cover 213.

[0064] Since a dust removal core 408 is installed in each heat dissipation cavity 406, dust in the external environment can be isolated from the inner cavity environment of the protective cover 213, thereby protecting the operation of the inner cavity components of the protective cover 213;

[0065] That is, by monitoring the wind force, the power generated by the rotation of the wind fan blades 304 can drive the cooling fan 404 to rotate and dissipate heat. Compared with the heat dissipation method of external energy transmission, it is more energy-saving and environmentally friendly, and can better ensure the safety and stability of wind power data monitoring.

[0066] Finally, it should be noted that the embodiments listed above are only used to illustrate the technical solutions of wind monitoring, data transmission and linked heat dissipation process of a device for secure data transmission in the wind power field provided by the present invention, rather than limiting the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features therein may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
