Description

Technical Field

[0001] This utility model relates to the field of corrosion-resistant concrete utility pole technology, specifically a corrosion-resistant concrete utility pole. Background Technology

[0002] Utility poles serve to support overhead power lines. Common types of utility poles include wooden poles, cement poles, and power transmission towers. Concrete poles are made of concrete and steel bars or wires, and they come in two types: prestressed and non-prestressed. Concrete utility poles are the most common.

[0003] Concrete utility poles are required during construction. However, when concrete utility poles are exposed to the air for extended periods, carbon dioxide in the air interacts with the concrete to form crystals. This crystallization process often involves an increase in volume, which can lead to cracking of the concrete material and, in severe cases, cause the concrete utility pole to topple over.

[0004] Therefore, we propose a corrosion-resistant concrete utility pole to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant concrete utility pole to solve the problem mentioned in the background art: when concrete utility poles are exposed to air for a long time, carbon dioxide in the air interacts with the concrete to form crystals, and the crystallization process is often accompanied by an increase in volume, which leads to cracking of the concrete material, and in severe cases, may even cause the concrete utility pole to collapse.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a utility pole body, the outer side of which is provided with a corrosion-resistant coating assembly. The coating assembly includes several pre-reserved reinforcing bar heads fixedly installed on the axial sidewall of the utility pole body. An inner layer of steel wire mesh is welded to each of the pre-reserved reinforcing bar heads, and an outer layer of steel wire mesh is welded to each of the pre-reserved reinforcing bar heads. An acrylic coating is bonded between the utility pole body and the inner layer of steel wire mesh. An epoxy resin coating is bonded between the inner layer of steel wire mesh and the outer layer of steel wire mesh, and a polyurethane coating is bonded to the outer layer of steel wire mesh.

[0007] Preferably, an anti-tipping assembly is provided on the axial sidewall of the utility pole body to prevent the utility pole body from tipping over. The anti-tipping assembly includes a fixing plate 1 disposed on one side of the utility pole body, a diagonal brace 1 fixedly installed on the fixing plate 1, and two support legs 1 fixedly installed on both sides of the diagonal brace 1. Both support legs 1 are fixedly connected to the fixing plate 1. A semi-circular clamp 1 is fixedly installed on the diagonal brace 1. Two limiting plates are fixedly installed on the fixing plate 1. The limiting plates and the fixing plate 2 are connected by screw threads. A nut is threaded onto the axial sidewall of the screw. A diagonal brace 2 is fixedly installed on the fixing plate 2. Two support legs 2 are fixedly installed on both sides of the diagonal brace 2. A semi-circular clamp 2 is fixedly installed on the diagonal brace 2.

[0008] Preferably, the lower end of the first fixed plate is provided with a reinforcing component for a stabilizing anti-tipping assembly. The reinforcing component includes a hole formed in the first fixed plate. A pointed cone is fixedly installed at the lower end of the first fixed plate. A displacement groove is formed on the pointed cone. A first chamber is formed on the pointed cone. A second chamber is formed on the pointed cone. A circular groove is formed at the end of the pointed cone. An operating rod is slidably installed on the displacement groove. An installation groove is formed on the operating rod. A round nail is slidably installed on the installation groove. A spring is provided between the round nail and the installation groove. A push rod is fixedly installed at the upper end of the operating rod.

[0009] Preferably, the arc-shaped surface of the second chamber is located at the lower end of the second chamber.

[0010] Preferably, the distance from the round nail to the second chamber is less than the distance from the end of the pointed cone to the operating rod.

[0011] Preferably, the dimensions of the first and second semi-circular clamps are matched with those of the utility pole body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. With the combination of inner wire mesh, reserved rebar ends, acrylic coating, outer wire mesh, epoxy resin coating, and polyurethane coating, the inner and outer wire mesh can prevent the coating from cracking and peeling. The acrylic coating has good adhesion and flexibility, the epoxy resin coating has good corrosion resistance, and the polyurethane coating has good water resistance, wear resistance, and UV resistance. This can effectively prevent the concrete pole body from being corroded by the external environment. With the cooperation of fixing plate one, nut, fixing plate two, semi-circular clamp one, and semi-circular clamp two, the pole body is prevented from being corroded and tilting. Moreover, this component can be recycled and is easy to disassemble and install.

[0014] 2. When the pointed cone is driven into the soil, the soil will compress the operating rod through the circular groove. With the cooperation of the operating rod, the mounting groove, the second chamber, the round nail and the spring, the round nail is driven into the soil, which increases the friction between the pointed cone and the soil, and further increases the stability of the fixing plate.

Two support legs 38 are fixedly installed on both sides of the diagonal brace 37. A semi-circular clamp 39 is fixedly installed on the diagonal brace 37.

[0023] The dimensions of the semi-circular clamp 1 34 and the semi-circular clamp 2 39 are matched with those of the utility pole body 1. The semi-circular clamp 1 34 and the semi-circular clamp 2 39 can clamp the utility pole body 1 to prevent the utility pole body 1 from tilting.

[0024] In this embodiment: First, the inner wire mesh 22 is welded to several pre-reserved rebar ends 21. Then, an acrylic coating 24 is applied. After the coating is applied and left to stand for a period of time, the outer wire mesh 23 is welded to several pre-reserved rebar ends 21. At this time, an epoxy resin coating 25 is applied. After leaving to stand for a period of time, a polyurethane coating 26 is finally applied.

[0025] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 3 and Figure 4 The lower end of the fixed plate 31 is provided with a reinforcing component 4 of the stabilizing anti-tipping component 3. The reinforcing component 4 includes a hole 41 opened on the fixed plate 31. A pointed cone 42 is fixedly installed at the lower end of the fixed plate 31. A displacement groove 43 is opened on the pointed cone 42. A first chamber 44 is opened on the pointed cone 42. A second chamber 45 is opened on the pointed cone 42. A circular groove 46 is opened at the end of the pointed cone 42. An operating rod 47 is slidably installed on the displacement groove 43. An installation groove 48 is opened on the operating rod 47.

[0026] The arc-shaped surface of the second chamber 45 is located at the lower end of the second chamber 45. Pressing the push rod 402 can return the round nail 49 back into the mounting slot 48.

[0027] The distance from the round nail 49 to the second chamber 45 is less than the distance from the end of the pointed cone 42 to the operating rod 47, to prevent soil from entering the first chamber 44 from the circular groove 46.

[0028] In this embodiment: when the pointed cone 42 is driven into the soil, the soil will squeeze the operating rod 47 through the circular groove 46, causing the operating rod 47 to slide upward. When the mounting groove 48 moves to the second chamber 45, the round nail 49 will exit from the second chamber 45 through the spring 401 and drive into the soil, increasing the friction between the pointed cone 42 and the soil, further increasing the stability of the fixing plate 31. When the component is removed, pressing the push rod 402 can push the soil out and restore the component to its original state.
