Description

TECHNICAL FIELD

[0001] The utility model relates to a stay wire rod technical field especially relates to a stay wire rod anticorrosion structure. BACKGROUND

[0002] The tower or pole is the support for supporting the power transmission line in the overhead transmission line, and is mostly supported by steel or reinforced concrete. Because the height of the tower is high, corresponding stay wires need to be assembled on the outer periphery of the tower. On the one hand, the stay wires improve the strength of the tower and bear the external load on the tower to reduce the material consumption of the tower and the cost of the line. On the other hand, the stay wires and ground anchors fix the tower on the ground to prevent the tower from tilting and collapsing.

[0003] In actual assembly, a stay wire rod needs to be configured between the stay wire and the ground anchor. The stay wire rod connects the stay wire on the ground to the ground anchor under the ground. However, many towers are located in paddy fields or wetlands, which leads to the corrosion of the underground part of the stay wire rod. According to investigations, the area of the stay wire rod that is 20-40 cm below the ground is most likely to be corroded because it can simultaneously contact abundant oxygen and moisture. This seriously affects the service life of the stay wire rod and leads to an unguaranteed grounding resistance, an increased lightning trip-out rate, and a serious threat to the safe operation of the line. UTILITY MODEL CONTENT

[0004] In view of the technical problems of the prior art, the utility model provides a stay wire rod anticorrosion structure.

[0005] To solve the above technical problems, the utility model provides the following technical scheme:

[0006] The stay wire rod anticorrosion structure comprises a protective shell, an adsorption structure, a water-blocking structure, and a sealing structure. The protective shell can be buckled on the corrosion-prone area of the stay wire rod. The sealing structures are respectively arranged at the two ends of the protective shell. The sealing structures can fill the gap between the protective shell and the stay wire rod. The water-blocking structure covers the stay wire rod. The adsorption structure is filled with a water-absorbing material. The adsorption structure is connected to the protective shell. The adsorption structure covers the water-blocking structure.

[0007] In actual use, the water-blocking structure is first covered on the stay wire rod. Then, the protective shell with the adsorption structure is connected to the stay wire rod. At this time, the protective shell is located at the outermost layer, and the adsorption structure and the water-blocking structure are located inward layer by layer. In this way, the corrosion-prone area of the stay wire rod is separated from water, preventing the stay wire rod from simultaneously contacting oxygen and water, thereby greatly reducing the corrosion probability of the stay wire rod. In this way, the service life of the stay wire rod is effectively prolonged, and the safety of the power transmission line is improved.

[0008] Further, the number of protective shells is two; the protective shells are provided with cavities for accommodating the adsorption structure, the water-proof structure and the stay rod; and the protective shells can be buckled to each other.

[0009] Further, the protective shells are provided with bolt grooves; the number of bolt grooves is multiple; and the bolt grooves are uniformly arranged from one end of the protective shell to the other end.

[0010] Further, the adsorption structure comprises a partition plate and an assembly plate; the assembly plate is connected to the protective shell; the assembly plate and the inner wall of the protective shell are arranged at intervals; and the partition plate is arranged between the assembly plate and the protective shell to enclose a cavity for accommodating water-absorbing material together with the assembly plate and the protective shell.

[0011] Further, the number of partition plates is multiple; and the partition plates are uniformly arranged from one end of the protective shell to the other end.

[0012] Further, the assembly plate is provided with a through groove; the through groove corresponds to the water-proof structure; and the through groove surrounds the water-proof structure.

[0013] Further, the sealing structure is made of rubber material; the sealing structure comprises sealing plugs and a sealing strip; the sealing plugs are arranged at two ends of the protective shell respectively; the sealing strip extends from one end of the protective shell to the other end; and the end of the sealing strip is connected to the sealing plug.

[0017] The following is a specific embodiment of the present application and further describes the technical solution of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0018] A stay rod anti-corrosion structure comprises protective shells 1, an adsorption structure 2, a water-proof structure 3 and a sealing structure 4. The number of protective shells 1 is two. The protective shells 1 are provided with cavities for accommodating the adsorption structure 2, the water-proof structure 3 and the stay rod. The protective shells 1 can be buckled to each other to be assembled on the stay rod. The protective shells 1 are provided with bolt grooves 11. The number of bolt grooves 11 is multiple. The bolt grooves 11 are uniformly arranged from one end of the protective shell 1 to the other end. Thus, the two protective shells 1 can be fixed together by bolts.

[0019] The adsorption structure 2 comprises a partition plate 21 and an assembly plate 22. The assembly plate 22 is connected with the protective shell 1. The assembly plate 22 is arranged between the inner wall of the protective shell 1. The assembly plate 22 is provided with a through slot 221. The through slot 221 corresponds to the waterproof structure 3. The through slot 221 surrounds the waterproof structure 3. The number of the partition plates 21 is multiple. The partition plates 21 are evenly arranged from one end of the protective shell 1 to the other end. The partition plates 21 are arranged between the assembly plate 22 and the protective shell 1 to form a cavity for accommodating the water-absorbing material together with the assembly plate 22 and the protective shell 1.

[0020] The waterproof structure 3 is made of plastic material. The waterproof structure 3 can wrap the stay-in-place rod.

[0021] The sealing structure 4 is made of rubber material. The sealing structure 4 comprises a sealing plug 41 and a sealing strip 42. The sealing plug 41 is arranged at two ends of the protective shell 1 respectively. The sealing strip 42 extends from one end of the protective shell 1 to the other end. The end of the sealing strip 42 is connected with the sealing plug 41. The sealing plug 41 and the sealing strip 42 are in interference fit with the protective shell 1.

[0022] In actual application, the waterproof structure 3 is wrapped on the easy-corrosion area of the stay-in-place rod. The waterproof structure 3 is a layer of water-impermeable plastic film. Then, the protective shell 1 is buckled on the waterproof structure 3. Thus, the adsorption structure 2 wraps the waterproof structure 3. Then, the two protective shells 1 are fixed together by bolts. During the fixing of the protective shell 1, the sealing plug 41 and the sealing strip 42 are extruded between the protective shells 1 and between the protective shell 1 and the stay-in-place rod, so that the sealing plug 41 and the sealing strip 42 are deformed correspondingly. In this way, the sealing plug 41 fills the gap between the protective shell 1 and the stay-in-place rod. The sealing strip 42 fills the gap between the two protective shells 1. Thus, the assembly is completed.

[0023] When the structure is buried in the ground with the stay-in-place rod, the protective shell 1 blocks the water from directly contacting the stay-in-place rod. At the same time, the sealing plug 41 and the sealing strip 42 prevent the water from entering through the gap between the protective shell 1 and the stay-in-place rod and the gap between the two protective shells 1. At the same time, even if a small amount of water penetrates, the water-absorbing material (as preferred, the water-absorbing material is water-absorbing resin) in the adsorption structure 2 can also absorb the water on the surface of the waterproof structure 3 through the through slot 221. Thus, the easy-corrosion area of the stay-in-place rod can be effectively prevented from directly contacting the water and oxygen by the utility model, so as to maximize the prevention of corrosion problems in the easy-corrosion area of the stay-in-place rod. On the one hand, the service life of the stay-in-place rod is effectively prolonged. On the other hand, the safety of the power transmission line is effectively improved.

[0024] At the same time, the water-absorbing material is separated into different blocks by the separating plate 21. On the one hand, the water-absorbing material can uniformly cover the water-proof structure 3. On the other hand, in actual application, the pull rod is usually arranged in an inclined manner. The separating plate 21 can effectively prevent the water-absorbing material from excessively accumulating in the same area under the influence of gravity, thereby avoiding the problem of water-absorbing function failure in some areas of the protective shell 1.

[0025] It is worth noting that the adsorbing structure 2 and the sealing structure 4 are also divided into two parts matched with the protective shell 1, so that when the two protective shells 1 are buckled, the corresponding structures can be jointly formed.

[0026] It is worth noting that only part of the structure of the pull rod is shown in the drawings, which does not represent the actual state of the pull rod.

[0027] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
