Description

Technical Field

[0001] The invention relates to a slope type weathering steel transmission iron tower conductor cross arm node anti-corrosion device, belonging to the technical field of weathering steel transmission iron towers. Background Art

[0002] Weathering steel transmission towers are a new type of material used in transmission tower structures. Due to their weather-resistant properties, the original galvanizing process for transmission towers is eliminated, thereby achieving a more environmentally friendly purpose. However, in actual applications, the applicant has found that the nodes of existing weathering steel transmission towers are prone to corrosion, which will reduce the service life of weathering steel transmission towers. Summary of the invention

[0003] Based on the above, the present invention provides a slope-type weathering steel transmission tower conductor cross-arm node anti-corrosion device to solve the technical problem that the existing weathering steel transmission tower is prone to corrosion at the nodes, thereby reducing the service life of the weathering steel transmission tower.

[0004] The technical solution of the present invention is: a slope-type weathering steel transmission tower conductor cross-arm node anti-corrosion device, wherein the device comprises:

[0005] horizontal gusset plate;

[0006] A vertical gusset plate, welded to the upper end surface of the horizontal gusset plate;

[0007] A horizontal main material, fixed to the lower bottom surface of the horizontal gusset plate;

[0008] A vertical main material is fixed on the side of the vertical node plate;

[0009] The upper end surface of the horizontal node plate is a slope structure with a high middle portion and low sides, and the upper portion of the horizontal node plate is located directly below the bottom of the vertical main material.

[0010] In one example, the longitudinal slope of the slope is greater than 1%. Also, the longitudinal slope of the slope is less than 5%.

[0011] In one example, the vertical main member has a predetermined distance from the welds of the horizontal node plate and the vertical node plate, so that the bottom end of the vertical main member does not contact the welds when shaking.

[0012] In one example, the apparatus further comprises:

[0013] A vertical diagonal material is fixed on the side surface of the vertical node plate;

[0014] There is a predetermined distance between the vertical diagonal member and the welds of the horizontal node plate and the vertical node plate, so that the bottom end of the vertical diagonal member does not contact the weld when shaking.

[0015] In one example, the predetermined distance is 1-3 cm.

[0016] In one example, the lower bottom surface of the horizontal gusset plate is a horizontal surface.

[0017] In one example, the apparatus further comprises:

[0018] The horizontal oblique material is fixedly arranged on the lower bottom surface of the horizontal node plate, and the limbs of the horizontal oblique material are arranged downward.

[0019] After a lot of in-depth investigations, the applicant found that due to the differences in the tower base material and the weld connection material, there is a potential difference between the two. When water accumulates in the welding node, water is used as an electrolyte, forming a loop inside and outside, causing electron migration, thereby accelerating the electrochemical corrosion effect of the weathering steel welding node. The generation of this electrochemical corrosion effect will have an adverse effect on the node's bearing capacity and production capacity. However, due to the large number of stiffening plates at the cross-arm welding nodes of the weathering steel tower conductors, the node connection structure is complex and the drainage is not smooth. Water is easily accumulated at the nodes during the rainy season, which is not conducive to the full life cycle use of the weathering steel tower.

[0020] The beneficial effect of the present invention is that after adopting the device, since the horizontal node plate corresponding to the bottom of the vertical node plate is a slope structure with a high middle part and low sides, when it rains, the rainwater will flow around along the slope of the horizontal node plate, and thus water will not accumulate on the horizontal node plate, especially at the corresponding positions of the vertical node plate and the horizontal node plate, thereby solving the problem of electrochemical corrosion caused by the formation of an electrical circuit between the vertical main material and the weld due to water accumulation on the horizontal node plate.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] See also Figure 1 and Figure 2 An embodiment of the present invention provides a slope-type weathering steel transmission tower conductor cross-arm node anti-corrosion device, which includes a horizontal node plate 1, a vertical node plate 2, a horizontal main material 6 and a vertical main material 4.

[0028] The horizontal gusset plate 1 is a plate-like structure. The vertical gusset plate 2 is welded to the upper end surface of the horizontal gusset plate 1. The horizontal main material 6 is fixed to the lower bottom surface of the horizontal gusset plate 1. The vertical main material 4 is fixed to the side surface of the vertical gusset plate 2. The upper end surface of the horizontal gusset plate 1 is a slope structure with a high middle and low sides, and the high part of the horizontal gusset plate 1 is located directly below the bottom of the vertical main material 4.

[0029] Specifically, the vertical node plate 2 is welded on the horizontal node plate 1 to form a weld 3, and the vertical main material 4 is fixed on the vertical node plate 2. Since the horizontal node plate 1 corresponding to the bottom of the vertical node plate 2 is a slope structure with a high middle part and low sides, when it rains, the rainwater will flow around along the slope of the horizontal node plate 1, and then water will not accumulate on the horizontal node plate 1, especially at the corresponding positions of the vertical node plate 2 and the horizontal node plate 1. This solves the problem of electrochemical corrosion caused by the formation of an electrical circuit between the vertical main material 4 and the weld 3 due to water accumulation on the horizontal node plate 1.

[0030] Furthermore, the longitudinal slope of the slope is greater than 1%, which can improve the drainage effect of the horizontal node plate 1. In addition, the longitudinal slope of the slope is less than 5%, which takes into account the drainage effect and the operability of welding.

[0031] Furthermore, the vertical main material 4 has a predetermined distance from the weld 3 of the horizontal node plate 1 and the vertical node plate 2, so that the bottom end of the vertical main material 4 does not contact the weld 3 when shaking. Specifically, by increasing the negative end of the vertical main material 4, that is, the distance between the vertical main material 4 and the horizontal node plate 1, it is ensured that the vertical main material 4 and the weld 3 do not collide, thereby avoiding the problem of electrochemical corrosion caused by the contact between the vertical main material 4 and the weld 3 to form an electrical circuit. In this embodiment, the predetermined distance is 1-3 cm.

[0032] Furthermore, the device further comprises a vertical oblique material 5, which is fixed on the side of the vertical node plate 2, wherein the vertical oblique material 5 has a predetermined distance from the weld 3 of the horizontal node plate 1 and the vertical node plate 2, so that the bottom end of the vertical oblique material 5 does not contact the weld 3 when shaking. As mentioned above, the negative end of the vertical oblique material 5, that is, the distance between the vertical oblique material 5 and the horizontal node plate 1, is increased to ensure that the vertical oblique material 5 does not collide with the weld 3, thereby avoiding the problem of electrochemical corrosion caused by the contact between the vertical oblique material 5 and the weld 3 to form an electrical circuit.

[0033] Furthermore, the lower bottom surface of the horizontal gusset plate 1 is a horizontal surface. This structure enables the horizontal main material 6 and the horizontal diagonal material 7 to be conveniently and stably fixed on the horizontal gusset plate 1 .

[0034] Furthermore, the device further comprises a horizontal diagonal member 7, which is fixed to the lower bottom surface of the horizontal gusset plate 1, and the limbs of the horizontal diagonal member 7 are arranged downward.

[0035] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
