Description

Technical Field

[0001] The utility model relates to the technical field of sacrificial anodes for conveying pipelines, and specifically relates to a sacrificial anode for conveying pipelines. Background Technique

[0002] A conveying pipeline is a pipeline system used to convey various fluid media and plays a crucial role in modern industry and life. The types of conveying pipelines are classified by material: metal pipelines, such as steel pipes and cast iron pipes, have high strength and pressure resistance and are suitable for conveying high-pressure and high-temperature fluids; non-metal pipelines, such as plastic pipes and fiberglass pipes, have characteristics such as corrosion resistance and light weight and are suitable for conveying corrosive media or occasions with requirements for weight. They are classified by use: oil and gas pipelines are used to convey energy media such as oil and natural gas; water supply and drainage pipelines are used to convey domestic water, industrial water, sewage, etc.; chemical pipelines are used to convey various chemical raw materials and products.

[0003] For some existing sacrificial anodes for conveying pipelines, when anti-corrosive treatment is carried out on the conveying pipeline, a sacrificial anode ring is installed on the outside of the conveying pipeline through bolts and nuts.

[0004] The following problems exist in some traditional sacrificial anodes for conveying pipelines. When anti-corrosive treatment is carried out on the conveying pipeline, when installing the sacrificial anode ring, it is rather cumbersome, not convenient for disassembly and subsequent maintenance and replacement. Therefore, we propose a sacrificial anode for conveying pipelines. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a sacrificial anode for conveying pipelines. When anti-corrosive treatment is carried out on the conveying pipeline, when installing the sacrificial anode ring, it is relatively simple, convenient for disassembly and subsequent maintenance and replacement, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a sacrificial anode for conveying pipelines, including an arc-shaped hoop one and a fixed installation mechanism;

[0007] Arc-shaped hoop one: Its lower end is rotatably connected to an arc-shaped hoop two through a rotating shaft. The inner walls of the arc-shaped hoop one and the arc-shaped hoop two together are provided with sacrificial anodes that are symmetric left and right. Iron cores are respectively arranged inside the sacrificial anodes, and wire meshes are respectively arranged on the front and rear sides of the sacrificial anodes.

[0008] Fixed installation mechanism: It includes a jack and a U-shaped insert. The lower ends of the arc-shaped hoop one and the arc-shaped hoop two are respectively provided with vertical blocks. Jacks are respectively opened on the front sides of the vertical blocks. The left and right ends at the rear side of the U-shaped insert are respectively installed in cooperation with the interiors of the adjacent jacks. When anti-corrosive treatment is carried out on the conveying pipeline, when installing the sacrificial anode ring, it is relatively simple, convenient for disassembly and subsequent maintenance and replacement.

[0009] Further, the fixed installation mechanism further includes a rectangular groove, a push plate, and an insertion block. Rectangular grooves are respectively formed at the left and right ends of the rear side of the U-shaped insertion strip. A push plate is slidably connected inside the rectangular groove, and insertion blocks are respectively fixedly connected to the outer ends of the push plate, facilitating insertion.

[0010] Further, the fixed installation mechanism further includes avoidance holes. Avoidance holes are respectively formed on the outer side surfaces of the rear ends of the vertical blocks, and the avoidance holes are respectively installed in cooperation with the adjacent insertion blocks, facilitating insertion.

[0011] Further, the fixed installation mechanism further includes a telescopic rod and a spring. Telescopic rods are fixedly connected between the inner side walls of the rectangular groove and the inner side surfaces of the adjacent push plates, and springs are respectively sleeved outside the telescopic rods, facilitating resilience.

[0012] Further, anti-slip convex blocks are respectively provided at the upper ends of the outer side surfaces of the first arc-shaped hoop and the second arc-shaped hoop, facilitating anti-slip.

[0013] Further, both the first arc-shaped hoop and the second arc-shaped hoop are elastic steel belt hoops, facilitating fixation.

[0014] Further, evenly distributed sacrificial anode connecting rods are respectively provided between the wire mesh and the iron core, facilitating conduction of electricity.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The sacrificial anode for the conveying pipeline has the following advantages:

[0016] By rotating the shaft, the vertical blocks at the lower ends of the two first arc-shaped hoops and the second arc-shaped hoops are aligned. Then, the U-shaped insertion strip is inserted into the insertion hole. Also, under the resilience of the telescopic rod and the spring, the insertion block is inserted into the avoidance hole. When replacement is needed, press the insertion blocks at both ends respectively, and the U-shaped insertion strip can be pulled. When anti-corrosion treatment is carried out on the conveying pipeline and the sacrificial anode ring is installed, it is relatively simple, facilitating disassembly and subsequent maintenance and replacement.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Arc-shaped hoop one 1: Its lower end is rotationally connected to arc-shaped hoop two 2 through rotating shaft 3. The inner walls of arc-shaped hoop one 1 and arc-shaped hoop two 2 together are provided with symmetric sacrificial anodes 4 on the left and right. Iron cores 5 are respectively arranged inside the sacrificial anodes 4. Wire meshes 6 are respectively arranged on the front and rear side surfaces of the sacrificial anodes 4. Anti-slip convex blocks 9 are respectively arranged at the upper ends of the outer side surfaces of arc-shaped hoop one 1 and arc-shaped hoop two 2. Both arc-shaped hoop one 1 and arc-shaped hoop two 2 are elastic steel belt hoops. Sacrificial anode connecting rods are evenly distributed between the wire meshes 6 and the iron cores 5;

[0024] Fixed installation mechanism 8: It includes a jack 81 and a U-shaped insert 82. Vertical blocks 7 are respectively provided at the lower ends of the first arc-shaped hoop 1 and the second arc-shaped hoop 2. Jacks 81 are respectively opened on the front sides of the vertical blocks 7.

The outer ends of the push plate 86 are respectively fixedly connected with insert blocks 87. The fixed installation mechanism 8 further includes an avoidance hole 88. Avoidance holes 88 are respectively opened on the outer side surfaces of the rear ends of the vertical blocks 7. The avoidance holes 88 are respectively installed in cooperation with the adjacent insert blocks 87. The fixed installation mechanism 8 further includes a telescopic rod 84 and a spring 85. Telescopic rods 84 which are evenly distributed are fixedly connected between the inner side walls of the rectangular groove 83 and the inner side surfaces of the adjacent push plates 86. Springs 85 are respectively sleeved on the outer parts of the telescopic rods 84. When anti-corrosion treatment is carried out on the conveying pipeline, first, the two arc-shaped sacrificial anodes 4 are respectively placed inside the first arc-shaped hoop 1 and the second arc-shaped hoop 2.

Then, the left and right ends at the rear side of the U-shaped insert 82 are respectively inserted into the interiors of the adjacent jacks 81. When the U-shaped insert 82 is inserted into the jack 81, the insert block 87 will contract inside the rectangular groove 83 under the extrusion of the inner wall of the jack 81.
