Description
Technical Field
The utility model relates to a door type suspension cable guyed tower for direct current transmission line belongs to transmission line technical field.
Background
Fig. 1 shows a self-standing door-type tower for a dc transmission line, which is mainly composed of two tower bodies and a cross arm connected between the two tower bodies, and compared with a conventional T-shaped or claw-shaped suspension tower, the self-standing door-type tower can reduce the pole pitch, reduce the torque, fully save the line corridor and protect the environment. However, the cross arm is stressed more, and the problem of cross arm deformation is often caused. In addition, the transverse bending moment of the iron tower is increased due to the cross arm, and the transverse bending moment generated by the vertical load of the wire is added besides the wind load, so that the torsion is larger.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the utility model provides a door type suspension cable guyed tower to the cross arm that solves current self-supporting door type tower existence is yielding to and the great problem of moment of torsion.
The technical scheme of the utility model is that: a door-type cable-stayed tower comprising:
a first tower body;
a second tower body spaced apart from and disposed adjacent to the first tower body;
it is characterized by also comprising:
the stay wire comprises a first end, a second end and a middle part, the first end is arranged on the outer side surface of the first tower body and is connected with a stay wire foundation arranged on the ground, the second end is arranged on the outer side surface of the second tower body and is connected with the stay wire foundation arranged on the ground, and the stay wire penetrates through the top of the first tower body and the top of the second tower body;
and the two V-shaped insulator strings are respectively hung between the first tower body and the middle position of the stay wire and between the second tower body and the middle position of the stay wire, and are used for hanging a lead.
The top of first body of the tower is provided with first ground wire cross arm.
And a second ground cross arm is arranged at the top of the second tower body.
The utility model has the advantages that: the utility model discloses the cross arm that will have self-supporting door type tower replaces formation door type suspension cable guyed tower with acting as go-between, both can avoid self-supporting door type tower's cross arm deformation problem, has the advantage that door type tower utmost point is little again, can also avoid the moment of torsion simultaneously, and the atress of two posts is mainly exactly perpendicular load, and the tower weight is also lightest.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Fig. 2 is a schematic structural diagram of a door-type cable-stayed pylon according to an embodiment. The gantry type suspension cable guyed tower in the embodiment comprises a first tower body 1, a first ground wire cross arm 3, a second tower body 2, a second ground wire cross arm 4, a guy wire 5 and two V-shaped insulator strings 6.
The first tower body 1 plays a supporting role and is mainly used for supporting the first ground wire cross arm 3, the pull wire 5, the V-shaped insulator string 6 and other parts.
And the first ground wire cross arm 3 is arranged at the top end of the first tower body 1. The first ground cross arm 3 is mainly used for suspending the ground.
The second tower body 2 is separated from the first tower body 1 and arranged adjacently, plays a supporting role, and is mainly used for supporting parts such as the second ground cross arm 4, the pull wire 5, the V-shaped insulator string 6 and the like.
And the second ground cross arm 4 is arranged on the top end of the second tower body 2. The second ground cross arm 4 is mainly used for suspending a ground wire. Preferably, the second ground cross arm 4 is opposite the first ground cross arm 3.
