Description

Technical Field

[0001] The utility model relates to the technical field of wind measurement towers, in particular to a high-wind-resistant offshore wind power wind measurement tower adopting a variable-section truss structure. Background Art

[0002] A wind tower is a tall 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. It was previously built by wind power companies, meteorological, and environmental protection departments for meteorological observation and atmospheric environment monitoring. The components of a wind tower include a tower base, tower column, crossbar, diagonal bar, anemometer bracket, lightning rod, and guy wire (free-standing towers do not have this).

[0003] At present, most truss-type wind towers are usually connected by welding. The truss structure is a structure composed of multiple rods and nodes. The rods and nodes are connected together by welding to form a stable overall structure. The welded connection can provide good structural strength and stability and is suitable for use under various meteorological conditions. If there is a problem with the welding connection, it will make repair and replacement more difficult, and it will be inconvenient to subsequently dismantle and maintain the damaged parts of the wind tower. Therefore, a high wind-resistant offshore wind power wind tower with a variable cross-section truss structure is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a highly wind-resistant offshore wind power anemometer tower with a variable-section truss structure, which has the advantages of being easy to subsequently dismantle and maintain the tower, and solves the problem of being inconvenient to subsequently dismantle and maintain damaged parts of the wind measurement tower.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a highly wind-resistant offshore wind power anemometer tower adopting a variable-section truss structure, comprising a support base, a plurality of support columns are fixed on the top of the support base, a plurality of first threaded columns are fixed on the top of the support columns, and tower components are arranged on the support columns.

[0006] The tower member includes three inclined columns, the bottom of the inclined column is fixedly connected to a lower fixed plate, the top of the inclined column is fixedly connected to an upper fixed plate, the top of the upper fixed plate is fixedly connected to a plurality of second threaded columns, the lower fixed plate is provided with a plurality of circular holes, the second threaded columns are adapted to the circular holes, a cross bar is fixedly connected between the three inclined columns, the left side of the cross bar is hingedly connected to a stabilizing rod, and the stabilizing rod is provided with two first connecting holes.

[0007] Furthermore, a second connection hole is provided on a side of the cross bar away from the stabilizing bar, and the second connection hole has the same hole diameter as the first connection hole.

[0008] Furthermore, a plurality of mounting holes are provided inside the support base, and the support base is a circular structure.

[0009] Furthermore, the number of the support columns is three, and reinforcing rods are fixedly connected between the three support columns.

[0010] Furthermore, the exteriors of the second threaded column and the first threaded column are both threadedly connected with fastening nuts, a bolt passes through the interior of the first connecting hole, and the exteriors of the bolt are threadedly connected with a hexagonal nut.

[0011] Furthermore, one end of the stabilizing rod away from the hinge is detachably mounted on the upper and lower adjacent cross bars by means of bolts and hexagonal nuts.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The high-wind-resistant offshore wind power measurement tower adopts a variable-section truss structure. The round hole on the lower fixing plate is aligned with the first threaded column on the supporting column, the first threaded column is passed through the round hole, and then the fastening nut is tightened to fix the bottom tower component on the supporting base.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The tower member 7 includes three inclined columns 71, the bottom of the inclined column 71 is fixedly connected to a lower fixed plate 72, the top of the inclined column 71 is fixedly connected to an upper fixed plate 73, the top of the upper fixed plate 73 is fixedly connected to a plurality of second threaded columns 74, the lower fixed plate 72 is provided with a plurality of circular holes 75, the second threaded columns 74 are adapted to the circular holes 75, a cross bar 76 is fixedly connected between the three inclined columns 71, the left side of the cross bar 76 is hingedly connected to a stabilizing rod 77, two first connecting holes 78 are provided inside the stabilizing rod 77, a second connecting hole 79 is provided on the side of the cross bar 76 away from the stabilizing rod 77, and the second connecting hole 79 has the same aperture as the first connecting hole 78.

[0021] It should be noted that the upper and lower adjacent stabilizing rods 77 are cross-fixed together by bolts 8 and hexagonal nuts 6, thereby increasing the connectivity between adjacent tower members 7 and improving the structural strength.

[0022] See also Figure 1 , Figure 3 There are three support columns 2, and reinforcing rods 3 are fixedly connected between the three support columns 2.

[0023] The three support columns 2 are connected and fixed by the reinforcing rod 3, so as to improve the connection performance between the three support columns 2 and ensure stable support.

[0024] It can be understood that by aligning the circular hole 75 on the lower fixing plate 72 with the first threaded column 4 on the supporting column 2, allowing the first threaded column 4 to pass through the circular hole 75, and then tightening the fastening nut 5, the bottommost tower component 7 can be fixed on the supporting base 1, and the lower fixing plate 72 is connected and fixed with the second threaded column 74 in sequence, so that multiple tower components 7 can be stacked and installed upward, and then the stabilizing rod 77 on the cross bar 76 is fixed to the adjacent cross bars 76 on the upper and lower sides by the hexagonal nuts 6 and bolts 8, and the stabilizing rods 77 on the upper and lower sides are cross-fixed. This method is convenient for installing the tower, thereby facilitating the subsequent dismantling and maintenance of the tower.

[0026] It should be noted that, since the inclined column 71 is an inclined rod, the cross-sectional area of ​​each upwardly mounted tower member 7 is different. The structural strength of the wind measurement tower is improved by the tower with a variable cross-section truss structure, thereby achieving high wind resistance and high stability.

[0027] The working principle of the above embodiment is as follows: during installation, first fix the support base 1 at the position where the tower needs to be installed through the fasteners and the mounting holes 9, then align the circular hole 75 on the lower fixing plate 72 with the first threaded column 4 on the support column 2, so that the first threaded column 4 passes through the circular hole 75, and then tighten the fastening nut 5, so that the bottom tower component 7 can be fixed on the support base 1, and then the adjacent tower components 7 are installed upward in sequence, so that the second threaded column 74 passes through the circular hole 75 and the fastening nut 5 is tightened to fix it, and then multiple tower components 7 can be installed upward, and then the stabilizing rod 77 is fixed to the adjacent cross bars 76 on the upper and lower sides through the hexagonal nuts 6 and bolts 8, and the stabilizing rods 77 on the upper and lower sides are cross-fixed. This method is convenient for installing the tower, thereby facilitating the subsequent dismantling and maintenance of the tower.
