[0036] like Figure 1 As shown, the present invention provides a fan device. Specifically, the fan device includes a foundation 1, a frame 2, a connecting part 6, and multiple fan heads 3.

[0037] Understandably, the foundation 1 has sufficient strength and rigidity to support the frame 2 and multiple fan heads 3, and is welded from stainless steel and other materials.

[0038] The frame 2 is installed on the foundation 1. Specifically, the connection method between the frame 2 and the foundation 1 is not limited; it can be welding or a rotatable connection, etc.

[0039] There are multiple mounting frames 201 provided on the frame 2, and the number of the mounting frames 201 is equal to the number of the fan heads 3, and they are arranged in one-to-one correspondence. Specifically, the sizes of the multiple mounting frames 201 are equal. Of course, it can be understood that the sizes of the mounting frames 201 can also be different, and can be specifically set according to needs.

[0040] The mounting frame 201 needs to have enough space to hold the fan head 3. The mounting frame 201 can be a rectangular frame, a circular frame, or the like.

[0041] Such as Figure 2 As shown, cross ribs 4 are arranged in the mounting frame 201. The cross ribs 4 are formed by at least 2 connecting ribs crossing each other. A guide rail 201a is arranged along the length direction of any connecting rib in the mounting frame 201. One end of the fan head is rotatably connected to the connecting part 6. It should be noted that the fan head 3 and the connecting part 6 are detachable, which is convenient for replacing the fan head 3 with the same or different sizes.

[0042] The connecting part 6 is slidably connected to the guide rail 201a, and the connecting part 6 can be locked at any position of the guide rail 201a. It should be noted that the connecting part 6 can be locked at any position of the guide rail 201a through fasteners such as bolts.

[0043] Furthermore, the present invention discloses that the cross-section of the guide rail 201a is in the shape of a swallowtail, and the cross-section of the connecting part 6 fits the cross-section of the guide rail 201a.

[0044] For the fan device provided by the present invention, since the frame 2 is arranged on the base 1, and multiple mounting frames 201 are arranged on the frame 2, and multiple fan heads 3 are respectively and correspondingly installed into the mounting frames 201, multiple fan heads 3 are installed on the same base 1, reducing the number of bases 1, saving materials, and reducing costs.

[0045] In addition, in the present invention, by arranging the guide rail 201a along the length direction of the connecting rib, the fan head 3 slides along the guide rail 201a through the connecting part 6, realizing the position adjustment of the fan head 3 in the mounting frame 201, and further realizing the adjustment of the distance between the fan heads 3 in adjacent mounting frames 201 to adapt to different environments.

[0046] In some embodiments, the present invention discloses that the cross ribs 4 are arranged in a cross shape, and the endpoints are respectively arranged at the positions of the two diagonals of the mounting frame 201.

[0047] It should be noted that the cross ribs 4 are not limited to cross-shaped ribs, and can also be ribs in the shape of a "rice" character, etc.

It is understood that the shape of the mounting frame 201 described above is only a preferred embodiment of the present invention; in practical applications, the mounting frame 201 can also be set to other regular or irregular shapes, etc.

[0050] To facilitate the rotation of the fan head 3 by the mounting frame 201 when the wind direction changes, this invention discloses that the mounting frame 201 is arranged in an arc along the direction from one side to the other. It should be noted that, alternatively, one side of the mounting frame 201 may have an arc-shaped protrusion, and the other side may have an arc-shaped groove, with both the arc-shaped protrusion and the arc-shaped groove arranged along the direction perpendicular to the rotation line of the mounting frame 201.

[0051] In some embodiments, the foundation 1 is a floating foundation, and an anchor chain 5 fixed to the seabed is installed on the floating foundation 1. It should be noted that the foundation 1 can also be installed on land.

[0052] Specifically, the foundation 1 includes four columns 101 and multiple connecting trusses 102. The four columns 101 form a rectangle, and the connecting trusses 102 fix the four columns 101 respectively to form the overall foundation 1.

[0053] Furthermore, the present invention discloses that the frame 2 is welded onto the base 1.
