[0027] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model provides a wind power prediction device. By arranging a retractable rod body, the rod body can be shortened during transportation for easy carrying. During maintenance, the rod body can be retracted to place a meteorological instrument and a control device for predicting wind power in a lower position for easy maintenance.

[0029] Please refer to Figures 1 to 4 The utility model provides a wind power prediction device including a rod body 10, a rod body 20, a connector 30 and a collection component 40. The rod body 10 is fixedly connected to the connector 30, the connector 30 is connected to the rod body 20, the rod body 20 is movably arranged on the rod body 10 through the connector 30, and the rod body 20 can be at least partially accommodated in the rod body 10, thereby shortening the overall length of the wind power prediction device; the collection component 40 is installed on the rod body 20, and the collection component 40 is used to collect data such as wind speed and wind direction for subsequent power prediction.

[0030] Please refer to Figures 1 to 4The rod body 10 is a hollow tubular structure. A base 11 is provided at one end of the rod body 10 away from the connector 30. The rod body 10 is fixedly connected to the base 11. A fixing hole 111 is provided on the base 11. The fixing hole 111 is used to fix the base 11 to the anchor bolts pre-buried in the concrete foundation. There are multiple fixing holes 111, and the multiple fixing holes 111 are distributed in a circular array on the fixing seat. Specifically, in this embodiment, the rod body 10 and the base 11 are fixed by welding.

[0031] Please refer to Figures 1 to 4 The rod body 10 is fixedly connected to the connector 30 through the flange 12. The connector 30 is generally a hollow tubular structure. A bushing 31 is provided inside the connector 30. The bushing 31 is threadedly connected to the connector 30. A plurality of blocks 311 are fixedly connected to the bushing 31. The blocks 311 are provided on the inner wall of the bushing 31. The plurality of blocks 311 are distributed in a circular array. In this embodiment, the number of blocks 311 is four. In other embodiments, the number of blocks 311 may be two, three, five or more, which is not specifically limited.

[0032] Please refer to Figures 1 to 4 The rod body 20 is a hollow tubular structure. A plurality of connecting blocks 21 are arranged at the bottom end of the rod body 20. The plurality of connecting blocks 21 are distributed in a circular array. The connecting blocks 21 correspond one to one with the clamping blocks 311. A clamping groove 211 is provided on the connecting block 21. The clamping groove 211 corresponds one to one with the clamping block 311. The clamping groove 211 is clamped with the clamping block 311. The connecting block 21 at least partially protrudes out of the rod body 20.

[0033] Please refer to Figures 1 to 4 The collection component 40 includes a meteorological instrument 41 and a collection terminal 42, which are fixedly mounted on the pole body 20, and are located at one end of the pole body 20 away from the pole body 10. The meteorological instrument 41 can collect data such as wind speed and wind direction, and the meteorological instrument 41 sends the collected data to the collection terminal 42, which then sends the data to the corresponding server, and the server performs wind power prediction.

[0034] In some of these embodiments, please refer to Figures 1 to 4 The end of the connector 30 away from the rod body 10 is fixedly connected with a retaining ring 32, wherein the inner diameter of the retaining ring 32 is slightly larger than the outer diameter of the rod body 20, and the rod body 20 can pass through the retaining ring 32 and be slidably connected with the retaining ring 32. Since the connecting block 21 at least partially protrudes from the rod body 20, the connecting block 21 will be blocked by the retaining ring 32 during the movement of the rod body 20, thereby playing a limiting role and preventing the rod body 20 from moving upward.

[0035] In some of these embodiments, please refer to Figures 1 to 4The connector 30 is provided with a plurality of limit bolts 33, which are threadedly connected to the connector 30, one end of which passes through the outer wall of the connector 30 and enters the inner cavity of the connector 30, and one end of which enters the connector 30 and is located above the connector block 21, and the limit bolts 33 correspond to the connector block 21 one by one. It can be understood that the distance between the limit bolts 33 and the connector block 21 is small, so as to prevent the rod body 20 from moving upwards a lot after installation.

[0036] In some embodiments, one end of the card block 311 close to the card slot 211 is rounded, and one side of the card slot 211 close to the card block 311 is also rounded. This arrangement facilitates the card block 311 to be inserted into the card slot 211.

[0037] In some of the embodiments, a plurality of ribs 112 are provided between the base 11 and the rod body 10. The ribs 112 are fixedly connected between the base 11 and the rod body 10 by welding. By providing the ribs 112, the connection strength between the base 11 and the rod body 10 can be improved, thereby improving the structural stability.

[0038] In some of the embodiments, identification lines (not shown) are provided on the connecting head 30 and the rod body 20. By providing identification lines on the connecting head 30 and the rod body 20, it is easy to observe whether the rod body 20 moves to the specified position during rising, falling or rotation during use.

[0039] The use process of a wind power prediction device provided by the utility model is as follows: when the wind power prediction device is in a retracted state, the rod body 20 is at least partially accommodated in the internal cavity of the rod body 10; when installing, the rod body 20 is first lifted upward, and the rod body 20 slides along the rod body 10 until the connecting block 21 on the rod body 20 passes the clamping block 311, and then the rod body 20 is rotated at a certain angle so that the connecting block 21 corresponds to the clamping block 311 one by one, and then the clamping block 311 is accommodated in the connecting block 21 one by one. The locking block 311 is inserted into the locking groove 211, and the limiting bolt 33 is threadedly connected to the connecting head 30. One end of the limiting bolt 33 entering the connecting head 30 is located above the connecting block 21, so as to prevent the rod body 20 from moving upward after installation, thereby playing a limiting role. When inspecting, the limiting bolt 33 on the connecting head 30 must be removed first to lift the rod body 20 upward, and then after rotating it to a certain angle, the rod body 20 can be at least partially accommodated in the rod body 1 10.

[0040] It should be noted that in this embodiment, the wind power prediction device includes two pole sections, namely pole section 10 and pole section 20. In other embodiments, the wind power prediction device may be provided with multiple pole sections, such as three, four or more sections.

[0041] In the wind power prediction device provided by the utility model, the pole body 20 can be at least partially accommodated in the pole body 10, thereby reducing the overall height of the wind power prediction device and placing the meteorological instrument 41 and the data collection terminal 42 on the top of the pole body 20 at a lower position, which is convenient for maintenance and use.

[0042] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0043] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
