Description

Technical Field

[0001] The present invention relates to the technical field of cement poles, in particular to an environmentally friendly cement pole with an anti-freeze cracking function. Background Art

[0002] As an essential supporting structure for power transmission and communication lines, cement poles play a vital role in the construction of power and communication infrastructure. Due to their significant advantages, such as high strength, good stability, strong durability, and relatively low cost, they are widely used in various line installation projects in cities, rural areas, and remote areas. Traditional cement poles are typically made of cement, sand, and gravel, using specific mold forming and curing processes. Their specifications and performance are designed and adjusted according to different usage scenarios and requirements, providing a solid foundation for the stable operation of power and communication networks.

[0003] As cement pole technology continues to evolve, CN202210047281.0 discloses a green and environmentally friendly composite cement pole and its production process. The cement pole covered by this patent features innovative optimizations in design and material selection, effectively saving material usage, reducing construction costs, and improving efficiency.

[0004] However, while some existing environmentally friendly cement poles have made some progress in environmental performance, they still face significant shortcomings when it comes to coping with harsh natural environments, especially low-temperature environments. Poor resistance to freezing and cracking is a particularly prominent issue. In cold regions, where winter temperatures are low, moisture inside cement poles easily freezes and expands, causing cracks on the pole surface and potentially even serious safety incidents such as pole breakage. This not only impacts the normal operation of power and communication lines, but also increases maintenance costs and safety risks. Therefore, improving the frost crack resistance of environmentally friendly cement poles has become a critical issue that needs to be addressed in the current field of cement pole technology. Summary of the Invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide an environmentally friendly cement pole with anti-freeze cracking function to improve the anti-freeze cracking ability.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0012] Preferably, the upper end surface of the combined section is provided with a plurality of annular ridges, and the plurality of annular ridges are distributed in concentric circles, and the lower end surface of the combined section is provided with an annular groove adapted to the annular ridges.

[0013] Preferably, the annular connecting frame at the top of the cable segment is detachably connected to a water shield by bolts, the water shield is configured to be umbrella-shaped, and a second limiting groove adapted to the limiting column is provided at the bottom of the water shield.

[0015] Preferably, the first elastic sealing pad and the second elastic sealing pad are both made of rubber material, and the thickness of the first elastic sealing pad and the second elastic sealing pad are both 2-5 mm.

[0016] Preferably, the material of the water adsorption coating is calcium oxide or silica gel.

[0017] Preferably, the waterproof coating is set to be one of an acrylic waterproof coating, a polyurethane waterproof coating and a silicone waterproof coating.

[0018] Preferably, the phase change energy storage material is one of paraffin, fatty acid or inorganic hydrated salt.

[0019] Preferably, the diameter of the weight-reducing cavity is 30% - 60% of the diameter of the concrete matrix.

[0020] The present invention has the following beneficial effects:

[0021] 1. Temperature control with phase-change energy storage materials: A ring-shaped temperature-control cavity is opened in the concrete matrix and filled with phase-change energy storage materials. In a low-temperature environment, the phase-change energy storage material can absorb the surrounding heat, slow down the temperature drop inside the cement pole, and reduce the risk of cracks or even fractures on the pole surface caused by internal moisture freezing and expansion, effectively improving the pole's anti-freeze cracking ability.

[0022] 2. Waterproof coating: Applying waterproof coating on the outer wall of the base and the inner wall of the temperature control cavity can prevent external moisture from entering the interior of the pole, reduce the internal moisture content, thereby reducing the possibility of freezing cracking caused by water freezing and expansion, and enhance the anti-freeze cracking performance of the pole.

[0023] 3. Water absorption coating: The inner wall of the weight-reducing cavity is coated with a water absorption coating made of calcium oxide or silica gel, which can absorb the moisture that may exist inside the pole, further reducing the damage to the pole caused by the freezing and expansion of internal moisture, and improving the anti-freeze cracking effect.

[0024] 4. Coordination of limiting posts and limiting grooves: In the connection sealing assembly, a plurality of annular evenly distributed limiting posts are fixedly set on the edge of the upper end face of the combination segment, and a first limiting groove adapted to the limiting posts is set on the lower end face, which can play a role in positioning and preliminary fixing during connection, ensuring accurate docking of adjacent combination segments and improving the stability and sealing of the connection.

[0025] 5. Elastic sealing gasket sealing: The first elastic sealing gasket is bonded to the inner wall of the first limiting groove, and the second elastic sealing gasket is bonded to the lower end surface of the combination section. When adjacent combination sections are connected, the elastic sealing gasket is deformed by extrusion and fills the gap in the connection part, effectively preventing moisture, air, etc. from entering the interior of the pole and enhancing the sealing effect.

[0026] 6. Coordination of annular ridges and annular grooves: The upper end face of the combined section is provided with multiple annular ridges distributed in a concentric circle, and the lower end face is provided with annular grooves adapted to the annular ridges. This structure increases the contact area and complexity of the connection part, further improves the tightness and sealing of the connection, and prevents external factors from affecting the interior of the pole.

[0027] 7. Detachable Connection Design: Each segment is detachably connected via a connecting seal assembly. The lowest segment is designated as the embedded segment, while the highest segment is designated as the line-laying segment. This design allows the pole to be installed and disassembled in sections according to actual needs, facilitating transportation and on-site construction, reducing installation difficulty and costs. Furthermore, if the pole is damaged or requires maintenance, specific segments can be easily replaced or repaired, improving maintenance efficiency.

[0028] 8. Thermal Conductive Ring and Engagement Groove Design: The top of the temperature-control chamber is connected to the first thermal conductive ring, and the bottom is connected to the second thermal conductive ring. An engagement groove that matches the first thermal conductive ring is provided in the concrete base below the second thermal conductive ring. When the first thermal conductive ring is fully inserted into the engagement groove, the first and second thermal conductive rings engage end-to-end. This design not only facilitates heat transfer between adjacent assembly sections, ensuring consistent temperature control, but also assists in positioning and securing the components during installation, making the installation process more accurate and convenient.

[0029] 9. Weight reduction cavity reduces weight: A cylindrical weight reduction cavity is opened in the center of the concrete matrix. The diameter of the weight reduction cavity is 30% - 60% of the diameter of the concrete matrix. Under the premise of ensuring a certain strength of the pole, it effectively reduces the weight of the pole, reduces material consumption and cost, and facilitates transportation and installation.

[0030] 10. Waterproofing: The annular connecting frame at the top of the line segment is detachably connected to an umbrella-shaped water shield via bolts. A second retaining groove, compatible with the retaining column, is located at the bottom of the shield. Multiple support frames are evenly arranged around the bottom ring, each with a second connecting hole bolted to the first. The water shield blocks rainwater from directly falling on the top of the pole, preventing it from flowing along the surface into the interior. This reduces the possibility of internal moisture and water accumulation, protects the internal structure and components of the pole, and extends the pole's service life.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] First embodiment

[0038] like Figures 1 to 2 As shown, an environmentally friendly cement pole with anti-freeze cracking function includes multiple combined sections 1; each combined section 1 is detachably connected by a connecting sealing assembly; the combined section 1 includes a cylindrical concrete base 101, the concrete base 101 is filled with a steel frame, a cylindrical weight-reducing cavity 102 is opened at the center of the concrete base 101, an annular temperature-control cavity is opened outside the weight-reducing cavity 102 in the concrete base 101, the temperature-control cavity is filled with phase change energy storage material 103, and the outer wall of the base and the inner wall of the temperature-control cavity are coated with a waterproof coating. 402, the inner wall of the weight reduction cavity 102 is coated with a water adsorption coating 401; the top of the temperature control cavity is connected to the first heat-conducting ring 141, and the bottom of the temperature control cavity is connected to the second heat-conducting ring 142, and the concrete base 101 is provided with a snap-fitting groove 143 adapted to the first heat-conducting ring 141 below the second heat-conducting ring 142; when the first heat-conducting ring 141 completely enters the snap-fitting groove 143, the first heat-conducting ring 141 and the second heat-conducting ring 142 are end-face fitted; the combination section 1 preset at the bottom is set as the embedded section, and the combination section 1 preset at the top is set as the wiring section.

[0039] like Figures 1 to 2As shown, the phase-change energy storage material 103 (such as paraffin, fatty acids, or inorganic hydrated salts) filled within the temperature-control cavity plays a key role in temperature control during ambient temperature fluctuations. When the external temperature drops, the phase-change energy storage material 103 undergoes a phase change, gradually transforming from liquid to solid. During this process, it absorbs heat from the surrounding environment, thereby slowing the temperature drop within the cement pole. This effectively prevents moisture from rapidly freezing inside the pole due to a sudden drop in temperature, reduces the stress caused by the freezing and expansion of moisture on the pole's internal structure, and reduces the risk of cracks or even fractures on the pole's surface. The waterproof coating 402 (such as an acrylic waterproof coating 402, a polyurethane waterproof coating 402, or a silicone waterproof coating 402) applied to the outer wall of the base and the inner wall of the temperature-control cavity forms an effective waterproof barrier. This prevents external moisture from penetrating the pole interior, reducing the moisture content within the pole. Even in relatively humid environments, the pole interior remains relatively dry, further reducing the possibility of cracking caused by freezing and expansion of moisture. The water-absorbing coating 401 (made of calcium oxide or silica gel) coated on the inner wall of the weight-reducing cavity 102 is water-absorbent. It absorbs any trace moisture that may be present inside the pole, maintaining a dry environment. Even if a small amount of moisture enters the pole, it is absorbed by the water-absorbing coating 401, preventing damage to the pole caused by moisture accumulation and ice expansion.

[0040] like Figures 1 to 2 As shown, the cylindrical weight-reducing cavity 102 opened at the center of the concrete matrix 101 effectively reduces the weight of the pole while ensuring the overall strength and stability of the pole. By reducing the amount of concrete used, the material cost is reduced, and the transportation and installation of the pole are also facilitated. Moreover, the provision of the weight-reducing cavity 102 will not have a significant impact on the carrying capacity of the pole, because the steel frame plays a role in enhancing the structural strength in the concrete matrix 101. The steel frame filled in the concrete matrix 101 provides a strong structural support for the pole. The steel bar has high strength and toughness and can withstand various tensile forces, pressures, bending moments and other forces to which the pole is subjected during use. Cooperating with the concrete, the steel frame can effectively prevent the pole from breaking or deforming when subjected to stress, thereby ensuring the long-term and stable use of the pole.

[0041] The first heat-conducting ring 141 connected to the top of the temperature-control chamber and the second heat-conducting ring 142 connected to the bottom, as well as the engaging groove 143 provided below the second heat-conducting ring 142 on the concrete base 101 and adapted to the first heat-conducting ring 141, play an important role in the connection and heat conduction of the pole. When adjacent assembly segments 1 are connected, the first heat-conducting ring 141 will completely enter the engaging groove 143 and engage the end face of the second heat-conducting ring 142. This design not only facilitates the conduction of heat between adjacent assembly segments 1, ensuring that the phase change energy storage material 103 in the temperature-control chamber can exert a uniform temperature control effect along the entire length of the pole, but also assists in positioning and fixing the assembly during connection, making the connection of adjacent assembly segments 1 more accurate and stable. Each assembly segment 1 is detachably connected via a connecting sealing assembly, including the coordination of the limiting column 201 with the first limiting groove 202, the annular ridge 271 with the annular groove 272, and the provision of an elastic sealing gasket. The coordination between the retaining post 201 and the first retaining groove 202, and the annular ridge 271 and annular groove 272, ensures accurate docking of adjacent assembled segments 1 during connection, preventing misalignment or loosening of the joints. The elastic sealing gasket (made of rubber) deforms under pressure, filling the gaps in the connection and effectively preventing moisture and air from entering the pole. This improves the seal of the connection and protects the pole's internal structures and components. Furthermore, this detachable connection facilitates pole installation, disassembly, and maintenance.

[0042] like Figures 1 to 2As shown, multiple annular, evenly distributed limiting posts 201 fixedly disposed on the edge of the upper end face of the assembly segment 1 cooperate with the first limiting groove 202 corresponding thereto on the lower end face of the assembly segment 1. When connecting adjacent assembly segments 1, the limiting posts 201 can be accurately inserted into the first limiting groove 202. This design provides precise positioning for the docking of the assembly segments 1, ensuring that adjacent assembly segments 1 will not be misaligned in the horizontal direction, making the connection process more accurate and efficient, and laying the foundation for subsequent stable connection and good sealing. Multiple concentrically distributed annular ridges 271 disposed on the upper end face of the assembly segment 1 match the corresponding annular grooves 272 on the lower end face of the assembly segment 1. When the assembly segments 1 are connected to each other, the annular ridges 271 embed into the annular grooves 272, further enhancing the positioning accuracy during the connection. This multi-level positioning structure can constrain the assembly segment 1 from different directions and angles, effectively preventing offset or shaking during the connection process, and ensuring the accuracy and stability of the connection. The annular connecting brackets 204, located on the outer walls of the upper and lower ends of the assembly segments 1, and the first connecting holes 205 uniformly arranged in a circular pattern on the annular connecting brackets 204 provide a stable connection between adjacent assembly segments 1. By bolting the first connecting holes 205 in adjacent annular connecting brackets 204, adjacent assembly segments 1 can be securely fastened together. This bolted connection offers high strength and reliability, capable of withstanding various external forces experienced by the pole during use, such as wind and its own weight. This prevents the assembly segments 1 from loosening or separating, ensuring the overall stability of the pole structure.

[0043] The first elastic sealing gasket 203 bonded to the inner wall of the first limiting groove 202 will be squeezed and deformed when the limiting column 201 is inserted into the first limiting groove 202. The deformation of the elastic sealing gasket can fill the tiny gap between the limiting column 201 and the first limiting groove 202, forming an effective sealing barrier to prevent external moisture, air and other substances from entering the interior of the pole. This can protect the internal structure and components of the pole from erosion by the external environment and extend the service life of the pole. The second elastic sealing gasket 206 bonded to the lower end face of the combination segment 1 will fit tightly with the lower end face of the upper combination segment 1 when the adjacent combination segments 1 are connected. Similarly, the second elastic sealing gasket 206 will deform after being compressed, filling the gap between the end faces of the two combination segments 1, further enhancing the sealing of the connection. The design of the double-layer elastic sealing gasket can provide a more reliable sealing effect, effectively prevent moisture penetration, and ensure a dry environment inside the pole.

[0044] like Figures 1 to 2As shown, both the first elastic sealing pad 203 and the second elastic sealing pad 206 are made of rubber. Rubber has excellent elasticity and flexibility, capable of deforming when subjected to external forces and returning to its original shape after the force is removed. This property allows the rubber sealing pad to adapt well to contact surfaces of varying shapes and sizes, filling gaps and achieving a sealing effect. Furthermore, the rubber material is also resistant to wear, corrosion, and aging, maintaining its sealing performance over time under varying environmental conditions, thereby extending the service life of the pole. The thickness of the first elastic sealing pad 203 and the second elastic sealing pad 206 is designed to be 2-5 mm, a carefully considered range. If the thickness is too thin, it may not deform sufficiently to fill the gap when subjected to compression, resulting in poor sealing. If the thickness is too thick, not only will the material cost increase, but it may also be damaged by excessive compression during installation, compromising sealing performance. A thickness of 2-5 mm ensures sufficient elasticity and deformability while balancing ease of installation and cost-effectiveness.

[0045] The water-absorbing coating 401 is made of either calcium oxide or silica gel, both of which have excellent water absorption properties. Calcium oxide can react chemically with water to produce calcium hydroxide, thereby fixing the water in the reaction product; silica gel has a large number of microporous structures and, through physical adsorption, absorbs water molecules from the surrounding environment into the micropores. Even if a small amount of water seeps into the cement pole, the water-absorbing coating 401 can absorb it promptly. This effectively reduces the moisture content inside the pole and prevents the water from freezing and expanding in low-temperature environments. Because water expands in volume when it freezes, if there is too much water inside the pole, the expansion force generated by the freezing may cause cracks or even fractures on the pole surface. The water-absorbing coating 401 reduces this risk and ensures the structural integrity of the pole.

[0046] Waterproof coating. 402 uses acrylic waterproof coating. 402, polyurethane waterproof coating. 402 or silicone waterproof coating. One of 402. Acrylic waterproof coating. 402 prevents moisture penetration by forming a continuous waterproof film; polyurethane waterproof coating. 402 has good elasticity and adhesion, can fit tightly to the surface of the substrate, fill tiny gaps, and prevent moisture from invading; silicone waterproof coating. 402 has excellent hydrophobicity, causing water to form water droplets and roll down on its surface, making it difficult to penetrate. These waterproof coatings. 402 is coated on the outer wall of the substrate and the inner wall of the temperature control cavity, forming a reliable waterproof barrier. It can effectively block moisture in the external environment, such as rainwater, humidity, etc., and prevent it from entering the interior of the pole. Avoid the degradation of the internal material performance of the pole due to the entry of moisture, while reducing the internal moisture content, further reducing the possibility of freezing and cracking, and extending the service life of the pole.

[0047] The phase change energy storage material 103 is selected from paraffin, fatty acid or inorganic hydrated salt. These materials have a specific phase change temperature range and can undergo phase change when the ambient temperature changes. When the outside temperature drops, the phase change energy storage material 103 gradually changes from liquid to solid, absorbing heat from the surrounding environment in the process; when the outside temperature rises, the material changes from solid to liquid, releasing the stored heat. In winter, the outside temperature is low, and the phase change energy storage material 103 absorbs heat during phase change, which slows down the rate of temperature drop inside the pole and makes the temperature inside the pole relatively stable. This avoids the rapid freezing of moisture inside the pole due to a sharp drop in temperature, reduces the stress on the internal structure of the pole caused by the expansion of moisture freezing, reduces the risk of cracks or even fractures on the surface of the pole, and plays a role in preventing frost cracking.

[0048] like Figures 1 to 2 As shown, the diameter of the weight-reducing cavity 102 is designed to be 30% - 60% of the diameter of the concrete matrix 101. Within this size range, the weight-reducing cavity 102 can effectively reduce the weight of the pole while ensuring the overall strength and stability of the pole. By reducing the amount of concrete used, the material cost is reduced, and the transportation and installation of the pole are also facilitated. Although the weight-reducing cavity 102 is provided, the steel frame plays a role in enhancing the structural strength within the concrete matrix 101, and the size of the weight-reducing cavity 102 is reasonably designed, it will not have a significant impact on the carrying capacity of the pole. The pole can still withstand various forces such as tension, pressure and bending moment it is subjected to during use, ensuring the long-term and stable use of the pole.

[0049] Second embodiment

[0050] like Figure 3 As shown, the annular connecting frame 204 at the top of the cable segment is detachably connected to the water shield 301 by bolts. The water shield 301 is arranged in an umbrella shape. A second limiting groove adapted to the limiting column 201 is provided at the bottom of the water shield 301. A plurality of support frames 302 are evenly arranged in an annular shape at the bottom of the water shield 301. A second connecting hole is provided on the support frame 302. The first connecting hole 205 is connected to the second connecting hole by bolts.

[0051] like Figure 3As shown, the water shield 301 is designed in an umbrella shape, which provides a large coverage area and excellent water conduction performance. When rainy, the umbrella-shaped water shield 301 acts like an umbrella, trapping most rainwater above the pole, preventing it from directly falling on the connection points of the combined section 1 and other key structures of the pole. At the same time, rainwater slides down the umbrella-shaped surface and away from the main body of the pole, reducing erosion and penetration of rainwater into the pole, effectively protecting the internal structures and components, and extending the pole's service life. The annular connecting frame 204 at the top of the cable section is removably connected to the water shield 301 via bolts. Bolted connection is a common and reliable connection method that provides sufficient connection strength to ensure that the water shield 301 is securely mounted on the top of the pole. During installation, tightening the bolts ensures that the water shield 301 fits tightly against the annular connecting frame 204, supporting the weight of the water shield 301 as well as any external forces such as wind, preventing the water shield 301 from loosening or falling off during use. There are multiple support frames 302 evenly arranged in a ring at the bottom of the water shield 301, and a second connection hole is provided on the support frame 302, which is connected to the first connection hole 205 on the ring connection frame 204 by bolts. This double connection structure further enhances the stability of the water shield 301. The support frame 302 can disperse the force exerted on the water shield 301, transfer part of the force to other parts of the pole, and reduce the concentration of force on a single connection point. At the same time, the multiple support frames 302 are evenly distributed, ensuring the balance of force on the water shield 301 in all directions, so that the water shield 301 can be more stably fixed on the top of the pole, and can maintain a good connection state even under harsh environmental conditions.

[0052] A second retaining groove at the bottom of the water shield 301, which mates with the retaining post 201, provides precise positioning during installation. When the water shield 301 is mounted on the top of the pole, the retaining post 201 precisely inserts into the second retaining groove, preventing the water shield 301 from shifting or misaligning horizontally. This positioning design ensures that the water shield 301 is correctly installed in the intended position, perfectly coordinating with the other structures of the pole. It also facilitates the installer's operation and improves installation efficiency and accuracy.

[0053] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all within the scope of protection of the present invention.
