Description

Technical Field

[0001] The utility model relates to a wind speed and direction measuring system, in particular to a wind measuring system. Background Art

[0002] With the continuous adjustment of the national energy strategy and the continuous increase in the intensity of environmental remediation, wind energy, as a typical representative of clean energy, has received more and more attention and development. At the same time, because wind energy has great uncertainty, wind speed and wind direction are constantly changing, so it is necessary to collect wind speed and wind direction parameters in time, and timely control the wind turbine group to change pitch and yaw, so as to improve the efficiency of the wind turbine. At present, some wind measurements use wind towers. Wind towers are a kind of towering tower structure used to measure wind energy parameters, that is, a tower-shaped structure used to observe and record the movement of near-ground airflow. In the past, they were mostly built by wind power companies, meteorological and environmental protection departments for meteorological observation and atmospheric environment monitoring. In recent years, with the development of wind power, wind towers have become a new type of tower for data collection of wind resources. However, there are the following problems with multiple groups of wind measuring devices installed at different heights on the wind tower: first, the location of some wind towers is relatively remote, and the power supply is unstable; second, the internal layout of the wind measuring device is chaotic, which makes it difficult to locate the problem point when sorting out the wind measuring device with problems; third, when there is a problem with the wind measuring device, it is difficult to replace it.

[0019] The tower body 1 is conical, with a rectangular cross section, a lightning rod 2 is arranged on the top, and a ladder is arranged inside for the convenience of workers to go up and down. In the embodiment of the utility model, four groups of wind measuring devices are arranged at heights of 10m, 20m, 30m and 40m, respectively. One end of the crossbar is located on the platform of the tower body, and the other end extends out of the tower body. The length of the crossbar is 3 to 6m.

[0020] The tower body 1 is provided with a first platform 3, a second platform 4, a third platform 5 and a fourth platform 6, each of which is provided with a crossbar. The first platform 3 is provided with a first crossbar 7, and a first wind measuring device 11 is fixedly installed at the other end of the first crossbar 7; the second platform 4 is provided with a second crossbar 8, and a second wind measuring device 12 is fixedly installed at the other end of the second crossbar 8; the third platform 5 is provided with a third crossbar 9, and a third wind measuring device 13 is fixedly installed at the other end of the third crossbar 9; the fourth platform 6 is provided with a fourth crossbar 10, and a fourth wind measuring device 14 is fixedly installed at the other end of the fourth crossbar 10.

[0021] like Figure 2 As shown, the photovoltaic device includes a photovoltaic panel, a photovoltaic controller, and a photovoltaic cell. The photovoltaic panel uses a photovoltaic panel with a power of 100W, which is used to convert light into electrical energy. The photovoltaic controller is used to convert the electricity generated by the photovoltaic panel into 12V, charge the photovoltaic cell, and power the control box and the wind measuring device. Furthermore, the wind measuring system is also connected to the mains, and the mains is connected to a lightning arrester, and then connected to a switching power supply. The switching power supply is used to convert AC220V into 12V direct current, and charge the photovoltaic cell through the photovoltaic controller and power the control box and the wind measuring device.

[0022] In the control box, the signal line connection of the wind measuring device is modularized, and the wind direction and wind speed sensor of the wind measuring device is connected to the collector through multiple sets of aviation plug connectors. The aviation plug connectors are located at the bottom of the control box for easy installation. The photovoltaic controller, lightning arrester, and collector can all be installed on the back panel in the control box, and the cables in the control box can be placed behind the back panel to make the wiring beautiful. Furthermore, the collector is provided with a display screen to display the device status in real time.

[0023] In an embodiment, the collector can collect data from five groups of wind measuring devices, each group corresponding to a crossbar, and send the data of the wind speed sensor and the wind direction sensor to the server. Furthermore, the collector is provided with a temperature and humidity sensor to send the temperature and humidity data to the server.

[0024] like Figure 3 As shown, in order to facilitate the replacement and maintenance of the wind measuring device, a slide rail structure is provided on each platform. Taking the fifth crossbar 20 for testing as an example, two slide rails are provided at the lower end of the fifth crossbar 20, namely, a first slide rail 21 and a second slide rail 22. The lower end of the fifth crossbar 20 is in a shape close to a circle, which matches the defined shape of the upper end of the slide rail. The two slide rails are mounted on the platform, and a fixing screw hole 23 is provided at the lower end of the slide rail. A first screw hole 24 is provided on the side of the first slide rail 21, and a second screw hole 25 is provided on the side of the second slide rail 22. Correspondingly, two through holes are provided on the right side of the fifth crossbar 20, and the two through holes on the right side are respectively a first through hole 26 and a second through hole 27. The positions of the two through holes correspond to the positions of the screw holes on the sides of the two slide rails, and are used to screw in nuts, thereby fixing the crossbar on the platform.

[0025] Similarly, two through holes are also provided on the left side of the fifth cross bar 20, which are used to correspond to the screw holes on the sides of the two slide rails. When the wind measuring device needs to be replaced and maintained, the nut on the right side of the fifth cross bar 20 is loosened, and then the fifth cross bar 20 is pulled and its left side is pulled to the platform. This makes it convenient to replace and maintain the wind measuring device fixedly installed on the left side of the fifth cross bar 20.

[0026] The wind speed and wind direction sensor of the wind measuring device includes a wind speed sensor and a wind direction sensor. The wind speed sensor is used to measure the wind speed, and the wind direction sensor is used to measure the wind direction. The data of multiple groups of wind measuring devices are connected to the aviation plug connector at the bottom of the control box through signal lines. The aviation plug connector design through modular design has the advantages of simple structure, convenient operation, labor saving and time saving, high reliability, low cost, and convenient after-sales processing, and has great practical value.

[0027] The wind measuring system uses solar energy for power supply, thus achieving stable power supply. Through the setting of the control box and the aviation plug connector, the lines of multiple wind measuring devices can be clearly sorted out. Through the design of the slide rail structure, the wind measuring devices with problems can be easily replaced. The utility model has a simple structure, convenient operation and stable structure.
